    AbstractRisk factors associated with 72-h mortality in patients with extremely high serum aspartate aminotransferase levels (AST; ≥ 3000 U/L) are unknown. This single-centre, retrospective, case-controlled, cross-sectional study obtained data from medical records of adult patients treated at Saitama Medical Center, Japan, from 2005 to 2019. We conducted a multivariate logistic after adjusting for age, sex, height, weight, body mass index, Brinkman Index, vital signs, biochemical values, updated Charlson Comorbidity Index (CCI) score, CCI components, and underlying causes. A logistic regression model with selected validity risks and higher C-statistic for predicting 72-h mortality was established. During the 15-year period, 428 patients (133 non-survivors and 295 survivors [cases and controls by survival < 72 and ≥ 72 h, respectively]) with AST levels ≥ 3000 U/L were identified. The 72-h mortality rate was 133/428 (31.1%). The model used for predicting 72-h mortality through the assessment of alkaline phosphatase, creatine kinase, serum sodium, potassium, and phosphorus levels had a C-statistic value of 0.852 (sensitivity and specificity, 76.6%). The main independent risk factors associated with 72-h mortality among patients with AST levels ≥ 3000 U/L included higher serum values of alkaline phosphatase, creatine kinase, serum sodium, potassium, and phosphorus.

    Background Coronavirus disease (COVID-19) is associated with a high mortality rate in older adults; therefore, it is important for medical institutions to take measures to prevent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission. This study aimed to assess the risk of SARS-CoV-2 infection among healthcare workers (HCWs) and the effectiveness of infection control measures. Methods This study had a cross-sectional component and a prospective cohort component. The cross-sectional component comprised an anti-SARS-CoV-2 antibody survey among HCWs at a medical center in Saitama City, Japan. In the prospective cohort component, HCWs at the same medical center were tested for anti-SARS-CoV-2 antibodies monthly over a 3-month period (May to July 2020) to assess the effectiveness of infection prevention measures, including personal protective equipment use. All participants in the cohort study also participated in the antibody survey. The primary outcome was anti-SARS-CoV-2 antibody (measured using Elecsys® Anti-SARS-CoV-2) positivity based on whether participants were engaged in COVID-19-related medical care. Other risk factors considered included occupational category, age, and sex. Results In total, 607 HCWs participated in the antibody survey and 116 doctors and nurses participated in the cohort study. Only one of the 607 participants in the survey tested positive for anti-SARS-CoV-2 antibodies. All participants in the cohort study were anti-SARS-CoV-2 antibody negative at baseline and remained antibody negative. Engaging in the care of COVID-19 patients did not increase the risk of antibody positivity. During the study period, a total of 30 COVID-19 in-patients were treated in the hospital. Conclusions The infection control measures in the hospital protected HCWs from nosocomially acquired SARS-CoV-2 infection; thus, HCWs should engage in COVID-19-related medical care with confidence provided that they adhere to infectious disease precautions.

    The risk factors associated with mortality in patients with extremely high serum C-reactive protein (CRP) levels are controversial. In this retrospective single-center cross-sectional study, the clinical and laboratory data of patients with CRP levels ≥40 mg/dL treated in Saitama Medical Center, Japan from 2004 to 2017 were retrieved from medical records. The primary outcome was defined as 72-hour mortality after the final CRP test. Forty-four mortal cases were identified from the 275 enrolled cases. Multivariate logistic regression analysis (MLRA) was performed to explore the parameters relevant for predicting mortality. As an alternative method of prediction, we devised a novel risk predictor, “weighted average of risk scores” (WARS). WARS features the following: (1) selection of candidate risk variables for 72-hour mortality by univariate analyses, (2) determination of C-statistics and cutoff value for each variable in predicting mortality, (3) 0–1 scoring of each risk variable at the cutoff value, and (4) calculation of WARS by weighted addition of the scores with weights assigned according to the C-statistic of each variable. MLRA revealed four risk variables associated with 72-hour mortality—age, albumin, inorganic phosphate, and cardiovascular disease—with a predictability of 0.829 in C-statistics. However, validation by repeated resampling of the 275 records showed that a set of predictive variables selected by MLRA fluctuated occasionally because of the presence of closely associated risk variables and missing data regarding some variables. WARS attained a comparable level of predictability (0.837) by combining the scores for 10 risk variables, including age, albumin, electrolytes, urea, lactate dehydrogenase, and fibrinogen. Several mutually related risk variables are relevant in predicting 72-hour mortality in patients with extremely high CRP levels. Compared to conventional MLRA, WARS exhibited a favorable performance with flexible coverage of many risk variables while allowing for missing data.

    The prevalence of atrial fibrillation (AF) increases with age, as does the proportion of patients with frailty. AF patients with frailty have a higher risk of stroke than those without frailty, and progressive frailty caused by stroke is also associated with a worse prognosis. Despite this, anticoagulant therapy tends to not be used in frail patients because of the risk of falls and bleeding complications. However, some studies have shown that anticoagulant therapy improves the prognosis in patients with frailty. An accurate assessment of the “netclinical-benefits” is needed in patients with frailty, with the aim of improving the prognoses of patients with frailty by selecting those who will benefit from anticoagulant therapy and actively reducing the risk of bleeding. A comprehensive intervention that includes a team of doctors and social resources is required. We herein review the effectiveness and bleeding risk associated with anticoagulant therapy in frail patients investigated in clinical studies.

    The risk factors associated with 72-hours mortality in patients with extremely high levels of random plasma glucose (RPG) remain unclear. To explore the risk factors predictive of 72-hours mortality in patients with extremely high RPG under heterogenos pathophysiological conditions. Retrospective, single-center, case-controlled cross-sectional study. University teaching hospital. Adults over age 18 were selected from the medical records of patients at the Saitama Medical Center, Japan, from 2004 to 2013. Extremely high RPG (≥500 mg/dl). Mortality at 72 hours following the RPG test, regardless of hospitalization or in an outpatient setting. Multivariate logistic regression analysis was performed with adjustment for age, sex, body mass index (BMI), and RPG level. The final prediction model was built using the logistic regression model with a higher C-statistic, specificity, and sensitivity. A total of 351 patients with RPG ≥500 mg/dl were identified within the 10-year period. The 72-hours mortality rate was 16/351 (4.6%). The C-statistics of the 72-hours mortality prediction model with serum albumin (ALB) and creatine kinase (CK) was 0.856. The probability of 72-hours mortality was calculated as follows: 1/[1 + exp (−5.142 + 0.901log (CK) −1.087 (ALB) + 0.293 (presence (1) or absence (0) of metastatic solid tumor)]. The sensitivity and specificity of this model was 75.5%. The independent risk factors associated with 72-hours mortality in patients with RPG ≥500 mg/dl are hypoalbuminemia, elevated CK, and presence of a metastatic solid tumour. Further research is needed to understand the mechanisms and possible interventions to prevent mortality associated with extremely high RPG.

    A 71-year-old woman with dermatomyositis (DM) received glucocorticoid steroid (GCS) and tacrolimus treatment. Relapse of skin symptoms was observed after tapering the GCS dose, and the patient tested positive for anti-transcriptional intermediary factor-1 gamma (TIF1-γ) antibody. Examinations for malignancy were repeatedly performed. However, no obvious findings indicative of a tumour were observed. Two years after, a retroperitoneal tumour was detected and pathologically diagnosed as poorly differentiated adenocarcinoma. The patient developed intestinal and biliary obstruction and eventually died of sepsis. Herein, we report the presence of anti-TIF1-γ antibodies in a DM patient with cancer of unknown primary site.

    Aggregatibacter actinomycetemcomitans, an etiological agent associated with periodontitis, endocarditis, and other infections, has rarely been implicated in spondylitis. A 70-year-old man with aortic valve replacement presented with a 4-month history of lower back pain and was diagnosed with spondylitis. Prolonged incubation of blood cultures and a biopsy yielded A. actinomycetemcomitans. Concurrent infective endocarditis (IE) was probable considering the infectious organism and the patients' prosthetic valve. The patient was treated with ceftriaxone and recovered well. Pyogenic spondylitis with possible concurrent IE may be caused by A. actinomycetemcomitans. Extended incubation and repeated cultures should be considered if HACEK infection is suspected.

    An 82‐year‐old man with untreated diabetes mellitus (DM) had anterior chest wall swelling and ulcers 2 years following blunt chest trauma. Contrast‐enhanced computed tomography revealed sternal fracture with osteolytic change and subcutaneous abscess. Blood and sternal cultures were positive for methicillin‐susceptible Staphylococcus aureus (MSSA). Transesophageal echocardiogram showed vegetation on the right coronary cusp and moderate aortic regurgitation. The patient received a diagnosis of infective endocarditis associated with chronic sternal osteomyelitis complicated by subcutaneous abscess because of MSSA. This case report showed that trivial trauma in patients with uncontrolled DM can cause chronic sternal osteomyelitis resulting in infective endocarditis.

    Peritonsillar abscess should be considered as a differential in patients presenting with fever, sore throat, and other cold‐like symptoms. Point‐of‐care transcutaneous cervical ultrasound is effective for diagnosing peritonsillar abscess in place of computed tomography (CT) imaging. Tongue movement during ultrasound examination will help confirm the presence of anatomical lesions on tonsils, and comparing the affected and unaffected sides will improve proper diagnosis.

    A 49‐year‐old‐Japanese woman visited us with a 1‐year history of verrucous lesions on the oral mucosa and fingers. Her past medical history was unremarkable except for chilblain in winter. She had no family history of collagen disease. Physical examination showed a well‐defined, hyperkeratotic erythematous plaque with ulceration on the palate and verrucous nodules on the fingers (Fig. 1a,b). She had no butterfly rash or discoid lesions on any other sites. Histology from both oral mucosa and finger revealed similar features; marked hyperkeratosis and acanthosis with perivascular lymphocytic infiltrates in the dermis. Liquefaction degeneration with a few necrotic keratinocytes was also found (Fig. 1c,d). We regarded the patient as verrucous lupus erythematosus (LE). Then, leukopenia (2,820/μl) and thrombocytopenia (67,000/μl) were observed as well as positive antinuclear antibody (ANA). However, the diagnosis of systemic lupus erythematosus (SLE) was not confirmed by the negative finding of anti‐DNA antibody, and the lack of requirements in 1997 updated ACR criteria for SLE validated back at that time. She developed skin ulcers on the left lower leg in the next two months (Fig. 2a). Four months later, laboratory examination revealed leukopenia (2,850/μl), thrombocytopenia (89,000/μl), low C3/C4 level (27 mg/dl, 3 mg/dl, respectively), positivity for ANA (1 : 640, speckled type), and anti‐Sm antibody (1 : 2). Histology of the leg ulcer exhibited no vasculitis but the occlusion of the vessels (Fig. 2b). Direct immunofluorescence revealed IgM, C1q, and C3 depositions on vessel walls as well as linear IgM deposition at basement membrane zone (Fig. 2c). Seven months later, she had seizure attacks. Then, SLE was diagnosed based upon ACR (1997) and SLICC criteria. Even under 2019 EULAR/ACR classification criteria,1 she was classified as SLE from total 24 points scored by the findings of fever (38.9 °C), leukopenia, thrombocytopenia, seizure, low C3/C4, and anti‐Sm antibody. Then, the patient was transported to us for dyspnea and high fever. Methylprednisolone pulse therapy was performed. Chest roentgenogram revealed extensive lung infiltrates. Aspergillus fumigatus was isolated from the sputum. Invasive aspergillosis was diagnosed. She died of multiple organ failure 8 months after the first visit.

    A 77-year-old man visited the hospital with a chronic cough persisting for 2.5 months accompanied with night sweats, weight loss (3.5 kg) and elevated C-reactive protein level. Chest CT of the lung field was normal, but aortic wall thickening accompanied by a contrast effect was noted. Positron emission tomography–CT (PET–CT) showed that the aorta and subclavian artery were inflamed, suggesting large-vessel vasculitis. Ultrasonography showed thickening of the superficial temporal artery wall (macaroni sign). Biopsy revealed lymphocytic infiltration in the tunica media and foreign-body giant cell reaction with the elastic lamina, resulting in a diagnosis of giant cell arteritis (GCA). The cough was considered a symptom of GCA as it resolved following prednisolone administration. Cough may rarely be an initial GCA symptom. However, for chronic cough accompanied with elevated inflammatory findings but with a normal lung field, imaging studies such as PET–CT are useful for the differential diagnosis.

    Background: Brucellosis, an important zoonotic disease, is endemic in various parts of the world. Patients diagnosed with brucellosis in developed countries are often travelers and immigrants from endemic areas. This pathogen is listed as biosafety level 3, which means that it is highly contagious and therefore a risk to clinical laboratory technicians. Case presentation: A 43-year-old Chinese man, who could not understand Japanese, visited our hospital because of an intermittent fever that had persisted for 5 months. Associated symptoms included muscle pain whenever he had a fever. He reported currently working as a welder in Japan. However, his previous employment working in animal husbandry in Heilongjiang, mainland China was not determined at the initial visit owing to language barriers. Two sets of blood culture showed nonfermenting gram-negative bacilli, initially misidentified as Ochrobactrum anthropi and subsequently identified as Brucella abortus. Six-week doxycycline and rifampicin were administered, with intravenous gentamicin for the initial 1 week. The patient recovered without relapse, confirmed by the negative result of a Brucella agglutination test. The patient’s wife and three laboratory technicians were required to undergo blood examinations, which revealed no evidence of infection; however, they received prophylaxis with 3 weeks’ doxycycline and rifampicin. Conclusion: In nonendemic countries, immigrants with imported brucellosis can be treated, to prevent secondary brucellosis infection, an occupational hazard among laboratory technicians. Greater attention is needed for positive findings of blood cultures, which may initially be misidentified as O. anthropi. When providing medical care for immigrants with fever of unknown origin, it is especially important for primary care physicians to overcome language barriers so as to assess pertinent information regarding their home country, such as previous employment, to prevent the spread the imported zoonoses in the era of a dramatically increasing number of immigrants and foreign travelers.

    Essential thrombocythaemia (ET) is characterised by elevated platelet count by a clonal stem cell disorder of megakaryocytes. Although thrombosis is a common complication of ET, splenic infarction (SI) is extremely rare. Here, we present the case of a 31-year-old Japanese man who presented with sudden-onset severe pain at the left hypochondrium on the day before admission. Enhanced abdominal CT revealed SI. The laboratory test results revealed a normal platelet count (439×109/L). Subsequently, the patient was diagnosed with ET because the platelet count gradually increased to 50.0×104/μL, and JAK2 V617F mutation was identified. Accordingly, low-dose aspirin was initiated, and no thrombotic episode occurred. Nevertheless, 6 months postdischarge, the platelet count gradually increased to >650 × 109/L, and anagrelide was initiated. This case demonstrates an unusual complication of acute SI due to ET under the rare situation of the normal platelet count.

    BACKGROUND: Systemic vasculitides constitute heterogenous conditions affecting many organs and systems through blood vessel inflammation. Although there are some classifications for vasculitis, several vasculitides are “unclassified” because they cannot be clearly assigned to one of the known entities. CASE REPORT: We report an autopsy case of a 67-year-old Japanese man who presented with fever, ocular pain, erythema, chest pain, and headache. The disease caused episcleritis, thrombophlebitis, extensive deep vein thrombosis, multiple pulmonary nodules and masses, hypertrophic pachymeningitis, and hyper-intensity areas in brain parenchyma on magnetic resonance images. Histopathology of the pulmonary nodule confirmed vasculitis affecting medium-to-small veins and arteries without necrotizing vasculitis or granulomatous inflammation. We diagnosed the patient with unclassified vasculitis based on the clinicopathological characteristics. Steroids in combination with immunosuppressants were used, but the disease was refractory and relapsing. The disease activity was eventually controlled with rituximab, but the patient died of bronchopneumonia. On autopsy, lung and brain findings indicated healed vascular inflammation. CONCLUSIONS: This is the first case report of unclassified vasculitis, which is characterized as medium-to-small-sized arteritis and phlebitis, causing episcleritis, thrombophlebitis, deep vein thrombosis, pulmonary vasculitis, and intracranial vasculitis. The clinical conditions share some similarities with granulomatosis with polyangiitis and Behçet’s disease; however, they meet no classification criteria of any specific vasculitis. More cases need to be analyzed to confirm our findings.

    Our case patient was a 38-year-old pregnant Japanese woman who underwent emergency Caesarean section because of massive vaginal bleeding due to a low-lying placenta. Immediately after delivery, she presented with rapidly progressive dyspnea. Contrast-enhanced computed tomography revealed bilateral pleural effusion, lung nodules, multiple liver tumors, and multiple osteolytic lesions. Accordingly, epidermal growth factor receptor-mutant advanced lung adenocarcinoma was diagnosed. This report highlights the occurrence of rapid progression of lung cancer following delivery that led to postpartum acute respiratory failure, rather than due to pulmonary thromboembolism associated with the existing deep venous thrombosis of the inferior vena cava.

    The" Stop! Syphilis Project" was started in Japan in 2018.A 29-year-old woman was admitted with fever, acute onset of posterior cervical pain, urodynia, and positive signs of meningeal irritation. Three months before admission, her heterosexual partner had been diagnosed with primary symptomatic syphilis with induration, but her initial serological screening tests for syphilis [rapid plasma reagin (RPR) test and Treponema pallidum hemagglutination (TPHA) test] were negative. She presented with a painless genital lesion at 2 months before the current hospitalization andwith skin rashes at 1 month before hospitalization; however, these were not recognized as symptomatic for syphilis. Additionally, urodynia appeared at 2 weeks before admission; the patient underwent serological rescreening for syphilis, which tested positive (RPR: 128-fold, TPHA: 640.0 titer unit), and posterior cervical pain appeared at 10 days before hospitalization. After emergent hospitalization, she was diagnosed with syphilitic meningitis without human immunodeficiency virus infection. Antimicrobial treatment with penicillin G was continued for 2 weeks, after which the fever, posterior cervical pain, urodynia, and rash subsided, and the patient was discharged on hospital day 16. On day 187 after starting treatment, RPR was 8-fold and TPHA was 262.4 titer unit. This case report highlights the fact that for the timely detection and appropriate treatment of syphilis, primary care physicians should recommend a repeated RPR test with incubation period taken into account, even in the absence of symptoms and even if initial screening results are negative.

    We herein report a case of a 31-year-old Japanese man who simultaneously had a positive influenza A virus antigen test result and Vogt-Koyanagi-Harada disease (VKHD), demonstrated by both diffuse multiple early hyperfluorescent points on fluorescein fundus photography and serous retinal detachments on optical coherence tomography. He had meningitis. It was difficult to determine whether the main cause of meningitis was influenza A or VKHD. After initial treatment with peramivir for influenza A and then methylprednisolone pulse with subsequent corticosteroid therapy for VKHD, his symptoms improved gradually. These findings suggest that influenza A virus infection contributes to the onset or exacerbation of VKHD.

    Common adverse effects of serotonin-norepinephrine reuptake inhibitors are nausea, dry mouth, dizziness and headache. We describe the case of a patient with dysosmia and subsequent dysgeusia associated with duloxetine. A 68-year-old Japanese woman with a history of type 1 diabetes mellitus, hypertension, insomnia and reflux esophagitis presented to a local hospital with bilateral leg pain; she was treated with duloxetine. However, after 4 weeks, she sensed rotten egg smell, experienced nausea and vomiting and was admitted to our hospital. We diagnosed dysosmia using the T&T olfactometer threshold test and dysgeusia using filter paper disk method. Taste was assessed using electrogustometry. We suspected that dysosmia and dysgeusia were adverse effects of duloxetine. After stopping duloxetine, her symptoms gradually subsided and the above test results improved, despite continuing the other ongoing medication. To the best of our knowledge, this is the first case report of dysosmia and dysgeusia associated with duloxetine.

    Objectives: Symptomatic cerebral infarction (CI) can occur in patients without main cerebral artery stenosis or occlusion. This study investigated the unique features of carotid artery plaque and white matter disease (WMD) in patients with symptomatic CI and transient ischemic attack (TIA) but without stenosis or occlusion of a main cerebral artery. Patients and methods: We studied 647 patients who underwent both carotid ultrasound examination and brain magnetic resonance images. Plaque score (PS), plaque number, maximal plaque intima-media thickness and grades of WMD were examined. Subjects were divided into four groups, the CI group, TIA group, myocardial infarction (MI) group and risk factor (RF) group. Plaque and WMD were analyzed in cerebral ischemia group (CI and TIA), compared to non-cerebral ischemia groups and to a high PS group and a high WMD grade group from the RF group. Results: Both of each value of plaque and grades of WMD in the cerebral ischemia group were significantly higher than those in other groups. Grades of WMD in the cerebral ischemia group were significantly higher than those in the high PS group, although there was no significant difference of the each value of plaque between the two groups. The each value of plaque in the cerebral ischemia group was also significantly higher than those in the high WMD grade group, although there was no significant difference of grade of WMD between the two groups. Conclusion: Simultaneous increases in carotid artery plaque and WMD are associated with symptomatic CI, which is not caused by stenosis or occlusion of a main cerebral artery.

    A 54-year-old Japanese man noticed painful swelling and redness of his left leg. He was admitted for treatment of cellulitis, which was accompanied with increased anti-streptolysin O and anti-streptokinase titers in his clinical course. After Piperacillin/Tazobactam administration, the skin lesion resolved. However, the patient then developed arthritis, palpable purpura, and intermittent abdominal pain, later found to be secondary to a severe duodenal ulcer. He was diagnosed with cellulitis-associated anaphylactoid purpura and was given prednisolone, which dramatically improved his symptoms. The anaphylactoid purpura was likely caused by Streptococcus-induced cellulitis, which was successfully treated with prednisolone. Association between these diseases is rare.

    The causes of chronic unilateral leg swelling include common manifestations such as venous insufficiency, varicosis, deep vein thrombosis, and persistent cellulitis, less commonly are secondary lymphedema (tumor, radiation, and surgery), pelvic tumors or lymphoma causing pressure on the veins, and reflex sympathetic dystrophy, and rarely congenital venous malformation, pregnancy, and iliac vein compression syndrome. Here, we describe a 78‐year‐old nonsmoking man with history of type 2 diabetes mellitus, dyslipidemia, and hypertension presented with left leg swelling that had been getting worse over several months.

    Background: When an internal carotid artery (ICA) occludes, a patient may develop cerebral infarction (CI). We investigated whether CI caused by ICA occlusion (ICAO) is associated with collateral flow through the anterior and posterior communicating arteries (ACoA and PCoA). Methods: In 100 patients with ICAO, we investigated CI and white matter disease by performing an MRI and the anatomy of the ACoA and PCoA were investigated by performing magnetic resonance angiography. All patients were divided into the symptomatic CI group or the no-CI group. The collateral flow pathway was estimated by the anterior cerebral artery (ACA)-PCoA score and the collateral flow volume after ICAO was estimated by the middle cerebral artery (MCA) flow score, based on how well the MCA was visualized. Results: Of 100 patients with ICAO, the symptomatic CI group included 36 patients. ACA-PCoA score and white matter disease grades were significantly higher in the CI group (indicating poor collateral flow). More than 80% of patients with an ACA-PCoA score of 4 (poor collateral) experienced symptomatic CI. Thirty-one symptomatic CI patients (86%) had an MCA flow score of 1 or 2 (decreased MCA flow). Conclusion: The ACA-PCoA score and white matter disease grade may suggest an increased risk of CI following ICAO.

    In pancreatic β-cells, glucose-induced closure of the ATP-sensitive K+ (KATP) channel is an initial process triggering glucose-stimulated insulin secretion (GSIS). This KATP-channel dependent pathway has been believed to be a central mechanism for GSIS. However, since the resting membrane potential of cells is determined by the balance of the net result of current amplitudes in outward and inward directions, it must be taken into consideration that not only KATP channel inhibition but also inward current via the basal opening of non-selective cation channels (NSCCs) plays a crucial role in membrane potential regulation. The basal activity of NSCCs is essential to effectively evoke depolarization in concert with KATP channel closure that is dependent on glucose metabolism. The present study summarizes recent findings regarding the roles of NSCCs in GSIS and GTP-binding protein coupled receptor-(GPCR) operated potentiation of GSIS.

    We report the case of a 71-year-old Japanese woman with adult-onset Still’s disease (AOSD) in whom macrophage activation syndrome (MAS) developed despite therapy with oral high-dose prednisolone and intravenous methylprednisolone pulse therapy twice. She was successfully treated with tocilizumab (TCZ). Soon afterward, her fever ceased and high levels of both ferritin and C-reactive protein levels decreased. Her course was complicated by disseminated intravascular coagulation, cytomegalovirus infection, andPneumocystis jiroveciipneumonia. After these were resolved, AOSD-associated MAS was well controlled. She was discharged on hospital day 87. Although biologics such as TCZ are becoming established for the treatment of AOSD, there is no recommended therapy for AOSD-associated MAS. Several biologics have been tried for this complication, but their efficacy and safety remain controversial. We reviewed reported cases of AOSD-associated MAS successfully treated with various biologics. TCZ initiation after adequate nonselective immunosuppressive therapy, such as methylprednisolone pulse therapy or a prednisolone-based combination of immunosuppressants, can be an effective treatment for AOSD-associated MAS. On the other hand, biologics given after insufficient immunosuppressive therapy may cause MAS. A strategy combining adequate immunosuppression and a biologic could be safe if special attention is given to adverse events such as opportunistic infections or biologic-associated MAS.

    An autopsy of a 70-year-old man with multiple bone metastases from a malignancy of unknown origin (MUO) and renovascular hypertension revealed an aortic intimal sarcoma (AIS) in the right renal artery accompanied by atherosclerotic changes. AIS appeared as aggregated mutton fat-like translucent particles arising from the intima of the branching portion of the right renal artery and was composed of undifferentiated, fine spindle cells with thicket-like proliferation. AIS was confirmed by immunohistopathology, showing the loss of the lumen lined by CD31-positive endothelium and the expression of CD31, keratin, and vimentin in the viable part of the tumor. In patients with MUO presenting with both bone metastases and an acute or sub-acute onset of renovascular hypertension, AIS in the renal artery may be responsible.

    Aortic graft infection is rare and carries a poor prognosis. Conventional management for prosthetic graft infection includes surgical debridement, removal of the infected graft, and reconstruction with a new graft prosthesis. However, these approaches are not feasible for some patients with anatomical difficulty for excision or severe comorbid medical illnesses. Here, we report a case of aortic prosthetic graft infection successfully treated with long-term appropriate antibiotics without surgical intervention. A 47-year-old man presented with high fever and back pain. He had undergone descending thoracic aortic reconstruction with a woven Dacron graft for post-ductal coarctation of the descending aorta at 15 years old. Contrasted-enhanced computed tomography (CT) of the chest demonstrated a low-density area around the graft. He was referred to our hospital for further treatment. The previous doctor reported that the blood cultures were positive for Staphylococcus aureus. Use of 67Ga scintigraphy detected a region of abnormal uptake around the graft. We initiated antibiotics with vancomycin, gentamicin, and piperacillin-tazobactam due to the possibility of both methicillin-resistant S. aureus and concomitant infections with anaerobic bacteria. After antimicrobial susceptibility testing revealed methicillin-susceptible S. aureus (MSSA), the antibiotics were switched to cefazolin. Cardiovascular surgeons did not recommend surgical intervention for the patient, so antibiotics were continued for a total of 8 weeks. Results from both a C-reactive protein test and CT showed improvement. The patient was discharged on hospital day 57, then continued oral cefaclor for 6 months thereafter and remained asymptomatic for over 6 months after the end of antibiotic therapy. The patient is now off antibiotics and free from re-infection without the use of any other antibiotics. Prosthetic aortic graft infections due to MSSA may circumvent surgical interventions with appropriate long-term antimicrobial therapies.

    A 51-year-old Japanese woman developed candidemia as an outpatient secondary to a Candida albicans upper urinary tract infection complicated by previously undiagnosed type 2 diabetes mellitus with poor glycemic control and ureterolithiasis. The patient did not have any risk factors typically associated with candidemia, such as an indwelling vascular catheter, parenteral nutrition or broad-spectrum antibiotic use. During the clinical course, her condition was complicated by unilateral candida endophthalmitis, which progressed despite the administration of systemic antifungal agents and ultimately required vitreous surgery. The etiology of candidemia in this patient and the reason she developed progressive ocular symptoms after starting antifungal treatment are reviewed.

    A 54-year-old Japanese man with diabetes mellitus (DM) since 41 years of age, was hospitalized due to warmth, swelling, and pain in both the lower left thigh and right wrist, and immobility. Although he had been on insulin therapy for 4 years, glycemic control was poor and he had developed diabetic retinopathy. For the preceding month, he had also been treated for diabetic foot gangrene involving the fifth toe of the right foot. Following hospitalization, microbiologic cultures of blood and pus from the posterior left thigh were positive for group A β -hemolytic Streptococcus. Empirical administration of penicillin G, clindamycin, vancomycin and γ-globulin proved ineffective and he developed necrotizing fasciitis, psoas abscess, and infectious spondylitis in the clinical course of streptococcal toxic shock-like syndrome (STSS). To treat STSS in this diabetic patient, general physicians of the Division of General Medicine worked in close coordination with specialists from emergency medicine, endocrinology, dermatology, orthopedics, and intensive care. We consider the following three factors to have been important in the successful management of this patient. The first factor was the inter- professional work among general physicians, specialists and other healthcare professionals. The second factor was the switch in antibacterial treatment to appropriate antibiotics. The third factor was the targeting of blood glucose levels to approximately 150 mg/dL. Thus, despite this very serious life-threatening illness, our patient was able to regain his ability to walk independently and was discharged on hospital day 106.

    The patient was a right-handed, 73-year-old female. She had mild memory dysfunction, but she could live independently. She had a past history of artificial aortic valve replacement and atrial fibrillation. However, she chose to discontinue warfarin. She was admitted to our hospital complaining of dizziness and visual dysfunction that had lasted for eight hours. A bedside neurological examination disclosed upper-field hemianopsia, central achromatopsia, and truncal ataxia. A cranial MRI showed acute infarcts in the posterior circulation, including the bilateral lower posterior lobes and the cerebellar vermis. Conservative treatment and bedside rehabilitation ameliorated her central achromatopsia and truncal ataxia. When she started gait training in the rehabilitation room on the 8th day of hospitalization, she could not return from the rehabilitation room to her hospital room by herself. Further examination suggested that she had developed landmark agnosia without prosopagnosia, so her family was advised to accompany her when she went out until there was improvement in her landmark agnosia. Six months later, she could walk around near her house by herself. Discovering landmark agnosia in a bedside check is so difficult that it might be missed, especially in people with cognitive decline. However, caregivers can be advised to support such patients so that they can go about their daily lives safely. When a patient has a large posterior lobe lesion, it is important to actively check for landmark agnosia and to advise the patient and family properly.

    In pancreatic beta-cells, closure of the ATP-sensitive K+ (K-ATP) channel is an initial process triggering glucose-stimulated insulin secretion. In addition, constitutive opening of background nonselective cation channels (NSCCs) is essentially required to effectively evoke depolarization as a consequence of K-ATP channel closure. Thus, it is hypothesized that further opening of NSCC facilitates membrane excitability. We identified a class of NSCC that was activated by exendin (ex)-4, GLP-1, and its analog liraglutide at picomolar levels. This NSCC was also activated by increasing the glucose concentration. NSCC activation by glucose and GLP-1 was a consequence of the activated cAMP/EPAC-mediated pathway and was attenuated in TRPM2-deficient mice. The NSCC was not activated by protein kinase A (PKA) activators and was activated by ex-4 in the presence of PKA inhibitors. These results suggest that glucose- and incretin-activated NSCC (TRPM2) works in concert with closure of the K-ATP channel to effectively induce membrane depolarization to initiate insulin secretion. The current study reveals a new mechanism for regulating electrical excitability in beta-cells and for mediating the action of glucose and incretin to evoke insulin secretion, thereby providing an innovative target for the treatment of type 2 diabetes.

    Parsonage-Turner syndrome (PTS), also known as neuralgic amyotrophy or brachial neuritis, consists of a complex set of symptoms including sudden onset shoulder pain, usually unilaterally, followed by progressive neurologic deficits such as motor weakness, dysesthesia and numbness. We report a case of a 45-year-old Japanese man with PTS, who was initially suspected of having orthopedic diseases, such as cervical spondylosis and suprascapular nerve entrapment syndrome. The patient presented with acute-onset severe pain in his right arm and neck, followed by muscle weakness. We diagnosed PTS by taking a detailed medical history, ruling out other differential diagnoses, and by considering the characteristic clinical symptoms and the denervation pattern identified by needle electromyography. High-dose corticosteroid therapy prednisolone (PSL) relieved the initial sharp pain and oral amitriptyline successfully relieved the residual nighttime pain. Doses of PSL and amitriptyline were tapered, pain was alleviated, and the patient returned to full-time work after discharge in one-and-a-half years. For prompt diagnosis, physicians should consider the possibility of PTS in patients with acute onset of severe arm pain or subsequent muscle weakness and muscle atrophy in the arm or shoulder girdle.

    Although proteinuria is highly prevalent in obese individuals, the association between proteinuria and low body weight is equivocal. In this study we determine whether low body weight is more strongly associated with proteinuria compared with normal weight. The association between body mass index (BMI) and proteinuria was examined in a cross-sectional study of 62,582 asymptomatic individuals aged 20-70 years without known kidney diseases recruited, based on the results of medical checkups in 1999. We also examined the incidence of recurrent or nonrecurrent proteinuria in an 8-year longitudinal analysis of 12,493 individuals without proteinuria at baseline. The prevalence of proteinuria showed a J-shaped relationship with BMI. Multivariate regression analysis showed that BMI of 27.0 kg/m(2) and above or 18.9 kg/m(2) and less was significantly associated with proteinuria relative to BMI 21.0-22.9 kg/m(2), even after adjusting for relevant cardiometabolic risk factors. In the longitudinal study, similar J-shaped relationships between the incident rates of proteinuria and baseline BMI groups were observed at post-baseline checkups. Baseline BMI 27.0 kg/m(2) and above was associated with significantly greater risk for recurrent and nonrecurrent proteinuria, whereas BMI 18.9 kg/m(2) and less was only associated with nonrecurrent proteinuria. Thus, obesity and low body weight may be associated with different types of proteinuria independent of cardiometabolic risk factors.

    We report the case of a 68-year-old Japanese man with rheumatoid arthritis who had progressive fatigue associated with hypercalcemia complicated by peripheral T-cell lymphoma (PTCL)-type methotrexate-associated lymphoproliferative disorder (MTX-LPD). Epstein-Barr virus (EBV) studies indicated presence of the virus in peripheral blood; however, axillary lymph-node biopsy specimen was negative. After the discontinuation of MTX, the Disease Activity Score 28-C-Reactive Protein (DAS28-CRP) improved from 2.9 to 2.2 and both hypercalcemia and lymphadenopathy remitted. We presume that both EBV reactivation under immunosuppressive state and PTCL-type MTX-LPD developing coincidentally may have contributed to hypercalcemia and consequent fatigue.

    When evaluating pleural effusion of undetermined etiology, malignant disease cannot be ruled out even if the effusion is transudative. Measurement of tumor markers in transudative pleural effusion (TPE) may aid in diagnosis, but the exact utility of these markers is unclear. We report the case of a 78-year-old man with paramalignant pleural effusion (PMPE) due to prostate cancer diagnosed by measuring prostate-specific antigen (PSA) in TPE. Androgen blockade therapy was effective in treating the PMPE. We discuss the value of PSA elevated in TPE for diagnosis of prostate cancer induced-PMPE.

    Spontaneous spinal epidural hematoma (SSEH) is an uncommon but clinically important disease, and delayed diagnosis of this condition can have severe consequences. General physicians should consider the possibility of SSEH when they encounter a patient with a sudden onset of unexplained cervical or back pain or subsequent radicular symptoms during anticoagulant therapy. Immediate magnetic resonance imaging is essential for early diagnosis. In this article, we present a rare case of an 80-year-old man who developed cervical SSEH during warfarin therapy.

    Acute pharyngitis is commonly encountered, but a definite etiological diagnosis is difficult. Although co-infection with Group A Streptococci (GAS) and Epstein-Barr virus (EBV) is uncommon, general physicians should consider the possibility of EBV co-infection in patients with GAS pharyngitis who fail to show prompt remission of symptoms following appropriate antibiotic treatment. In this article, we present a rare case of a 16-year-old girl who had co-infection with GAS and EBV. She developed acute glomerulonephritis and left ventricular dysfunction in an overlapping manner. We were able to follow her until she healed, and herein describe the pathogenesis of her systemic and pulmonary edema.

    Background: Low serum amylase is likely to be associated with obesity and metabolic abnormalities, which are often accompanied by impaired insulin action. However, it is unclear whether low serum amylase is associated with impaired insulin action in clinical settings. Therefore, we investigated the associations of low serum amylase with plasma insulin levels, and obesity-related parameters, including leptin. Research design and methods: We measured serum amylase, plasma insulin, obesity-related parameters such as leptin, cardiometabolic risk factors, and anthropometric parameters in a cross-sectional study of 54 asymptomatic subjects (mean age 48.6 ± 7.6 years) who were not being treated for diabetes. Results: Body mass index (BMI) and plasma glucose at 120 min after a 75-g oral glucose tolerance test (OGTT) were significantly higher in subjects with low serum amylase (< 60 IU/l, n = 21) than in those with normal-to-high serum amylase (n = 33) (P = 0.04 and P = 0.004, respectively). In univariate correlation analysis, serum amylase was significantly correlated with BMI alone (r = -0.39, P = 0.004). By contrast, multivariate logistic analysis showed that each 1-SD increase in quantitative insulin sensitivity check index, and each 1-SD decrease in plasma insulin OGTT at 0 and 60 min, homeostasis model assessment of insulin resistance (HOMA)-R, and HOMA-β were significantly associated with low serum amylase, particularly after adjusting for BMI. When subjects were divided into three groups according to HOMA-R, serum amylase levels were significantly lower in subjects with HOMA-R > 2.5 (n = 23) compared with subjects with HOMA-R 1.6-2.5 (n = 10) (61.1 ± 13.6 U/ml versus 76.9 ± 20.5 U/ml, Bonferroni test, P = 0.02), but not compared with subjects with HOMA-R<1.6 (n = 21; 62.7 ± 17.6 U/ml). Similar trends were observed when subjects were divided according to plasma leptin and fasting plasma insulin levels. Conclusions: These results suggest that after adjusting for BMI, low serum amylase is associated with decreased basal insulin levels and insulin secretion, as well as high insulin resistance. The nature of these associations remains to be elucidated in further studies.

    A 78-year-old woman with a 3-month history of right nasal obstruction and an oppressive feeling in her right cheek was referred to an otolaryngologist at our center. Computed tomography (CT) scan showed a mass in the right nasal canal and maxillary sinus. Biopsy was performed through the right nasal canal; however, a diagnosis could not be made. On the admission day, she experienced a sudden loss of appetite and back discomfort. Subsequently, she was referred to the Division of General Internal Medicine. Review of systems (ROS) after the consultation indicated a weight loss of 10 kg within 2 months and a small subcutaneous nodule in the left lower abdomen. Tenderness of the thoracic vertebrae and right hypochondralgia were noted on examination. Enhanced CT scan showed multiple metastases to the liver and sacral bone. Immunohistochemical staining of the completely resected subcutaneous nodule was positive for S100, HMB45 and vimentin, but was negative for epithelial membrane antigen, cytokeratin, and CD30. The pathological diagnosis was that of an amelanotic melanoma. The performance status of the patient declined, and she died the 19th hospital day. At autopsy, the right nasal sinus was inundated with a white pultaceous mass, the histological findings of which were the same as those obtained from the previous biopsy of amelanotic melanoma, and extensive multiple metastases to the liver, lung, heart, thyroid, peritoneum, retroperitoneum, ribs, thoracic vertebrae, and iliac bone were observed. The TNM staging for malignant melanoma was pT4N0M1c. ROS is an important tool not only for diagnosis, but also for determining the patient’s general condition. Obtaining the ROS is an overarching approach for organ specialists who care for patients with malignancy; it enables them to evaluate metastasis to organs other than the target organ.

    We aimed to examine whether circulating levels of osteocalcin, bone formation marker secreted from osteoblast, are changed in glucose-intolerant subjects without taking glucose lowering agent, because bone metabolism is reportedly related to glucose metabolism in animal and human studies. According to 75 g oral glucose tolerance test (75 g-OGTT), all subjects (47.6 ± 10.2 years of age; 45 men and 10 women) were divided into three categories: normal glucose tolerance (NGT, n = 39), prediabetes (PDM, n = 11) that included impaired fasting glucose (IFG) and impaired glucose tolerance (IGT), and diabetes (T2DM, n = 5). Serum osteocalcin levels were increased in T2DM as compared to NGT. In all the participants, simple regression analysis model revealed positive correlation of osteocalcin with plasma glucose at 120 min, G(120), on 75 g-OGTT, negative with both creatinine and Ln(CRP), but not significantly with fasting plasma glucose. Osteocalcin and leptin were independent variables for G(120) ( P = 0.026 and 0.035, respectively). In multinomial logistic analysis leptin (PDM vs. NGT: P = 0.02 Odds ratio (OR) of 1.05, 95% confidence intervals, 1.007–1.084) and osteocalcin (T2DM vs. NGT: P = 0.038, OR 10.8, 1.13–102.4) were independently associated. We conclude that circulating osteocalcin and leptin are related to glucose intolerant state.

    The patient was a 31-year-old man with bipolar disorder who developed acute lithium toxicosis induced by the new onset of diabetes mellitus. He was being treated with lithium carbonate and presented with loss of consciousness. He had been drinking a large quantity of soft drinks because of increasing thirst over the previous 2 months. At a regular hospital visit, his HbA1c was found to be 13%. He was treated with oral hypoglycemic medication despite the presence of ketosis. Nine days later, he was transported to our hospital unconscious. His plasma lithium level was 4.0 mEq/L. When he finally regained consciousness, he had severe residual cerebellar ataxia. Hypovolemia induced by high blood glucose causes prerenal acute renal failure. Once renal dysfunction has occurred, the serum lithium level quickly reaches toxic levels. Lithium toxicosis related to diabetes mellitus has rarely been reported. The mechanism of cerebellar ataxia due to lithium poisoning is not yet clear. This instructive case is presented along with a review of the relevant literature.

    The case of a 42-year-old man with amoebic colitis associated with acquired immunodeficiency syndrome (AIDS) treated with tinidazole following an allergic reaction to metronidazole is presented. The patient had a 3-month history of persistent diarrhea. At another hospital, amoebic colitis was diagnosed by colonoscopy, and metronidazole was prescribed. A rash appeared on his limbs and chest 3 days after metronidazole was initiated, so it was discontinued. When the patient subsequently developed appetite loss, weight loss, exertional dyspnea, and palpitations, he was referred to our hospital. We found that he had Pneumocystis jiroveci pneumonitis associated with AIDS. The patient denied sexual intercourse with men. His HIV-RNA viral load was 2.0×106 copies/ml, and his CD4 cell count was 63 /μl. His symptoms improved with sulfamethoxazole-trimethoprim and prednisolone. On the 11th day after admission, his temperature rose to 38°C, and he had frequent, watery diarrhea. On the 15th day, colonoscopy showed erosive lesions along the entire colonic mucosa and amoebiasis in the specimen biopsy. On the 17th day, the patient began to take metronidazole. On the 22th day, his temperature rose to 38°C again, but no skin rash appeared. Because of the increased temperature, the medication was switched from metronidazole to tinidazole. As a result, his temperature returned to normal the next day, the frequent diarrhea decreased, and the results of the fecal occult blood tests became negative. The patient was discharged on the 43rd day, with a plan to receive highly active anti-retroviral therapy on an outpatient basis. Because both metronidazole and tinidazole are used to successfully treat amoebic colitis in Japan, we hope that the healthcare payment system will begin to cover the use of these drugs as soon as possible.

    Background: Since Japan's new compulsory clinical resident training system started in 2004, many medical students have visited the Division of General Medicine (G/M) at the Saitama Medical Center of Jichi Medical University. It is unclear which background factors influenced visiting medical students' (visitors) and residents' decisions to apply to the clinical training program for residents or continue into the subsequent clinical fellowship program. Purpose: The present study aimed to identify important background factors that influenced visitors' decisions to apply to both the clinical training program for residents and the subsequent clinical fellowship program, regardless of whether visitors participated in the G/M shadowing program. Participants and Methods: Logistic regression analyses were conducted to identify significant background factors among 581 visitors, 397 candidates for the clinical training program for residents, and 81 residents who had completed the clinical training program for residents from 2003 to 2009. Results: Older visitors were more likely to apply to the clinical training program for residents. Visitors or residents whose hometowns were outside of the Kanto metropolitan area were the least likely to apply to the clinical training program. Both the frequency of visits and the total number of days spent visiting increased the possibility of applying to the clinical training program and participating in the subsequent clinical fellowship program. These decisions were not influenced by participation in the G/M shadowing program. Conclusion: "Shared territorial bonding" between visitors and residents from hometowns nearby and the location of the teaching hospital were important factors affecting the decision to apply to the residency program or the subsequent clinical fellowship program.

    Stiff-person syndrome (SPS) is characterized by generalized stiffness of the muscles. Although the substratum responsible for producing stiffness is mainly concentrated in the spinal cord, a recent study using electromagnetic stimulation has revealed hyperexcitability of the cerebral motor cortex is related to SPS. ln this report,, we present a SPS patient with increased excitability of the cerebral motor cortex suggested by sensory evoked potentials (SEPs). The patient was a 70-year-old woman who first noticed stiffness of the legs 10 years ago. A local physician diagnosed the condition as “dystonia” and prescribed diazepam, which ameliorated the symptoms. She was admitted to our hospital at the age of 70 because of right hemiparesis and dysarthria. Cranial MRI showed infarct i n the left pre\Rolandic area. We diagnosed cerebral embolism and therapy with tissue plasminogen activator (tPA) dramatically ameliorated the patient’s neurological deficit. However, on the fourth day of admission, both the patient’s legs and trunk became markedly stiff, 1ike a board, probably due to the cessation of diazepam. Neurological exanimation showed rnarked stiffness of the lower limbs and trunk, and intermittent muscle spasms i n the femoral muscles. Stiffness was exacerbated by passive movement, but was not induced by touch stimuli or tapping the tendon. Deep tendon reflexes were normal and the sensory system was intact. Laboratory tests showed a high titer of anti-glutamate decarboxylase (GAD) antibody (69,000 U/ml) and a diagnosis of SPS was made. Surface electromyograms showed continuous and spontaneous discharges Iacking reciprocity between agonist and antagonist muscles. Giant SEPs were evoked by electrical stimulation of both tibial nerves (right 125, left 17.8 ptV). However, stimulation of the median nerves of both arms, where stiffness was absent, did not elicit giant SEPs (right 5.3, left 6.0 ptV). The waveforms of giant SEPs of this case were similar ’to those previously reported for cortical reflex myoclonus, suggesting hyperexcitability of the cerebral cortexes. Re-administration of diazepam ameliorated the stiffness and the amplitudes of the SEPs were reduced significantly to right 6,0 pt V, left 6,8 pt V. Our case results suggest that hyperexcitability in the primary motor cortex contributes to the pathophysiological mechanism underlying the “stiffness” in SPS.

    Voltage-gated potassium channels (Kv channels) play a crucial role in formation of action potentials in response to glucose stimulation in pancreatic beta-ells. We previously reported that the Kv channel is regulated by glucose metabolism, particularly by MgATP. We examined whether the regulation of Kv channels is voltage-dependent and mechanistically related with phosphorylation of the channels. In rat pancreatic beta-cells, suppression of glucose metabolism with low glucose concentrations of 2.8 mM or less or by metabolic inhibitors decreased the Kv2.1-channel activity at positive membrane potentials, while increased it at potentials negative to -10 mV, suggesting that modulation of Kv channels by glucose metabolism is voltage-dependent. Similarly, in HEK293 cells expressing the recombinant Kv2.1 channels, 0 mM but not 10 mM MgATP modulated the channel activity in a manner similar to that in beta-cells. Both steady-state activation and inactivation kinetics of the channel were shifted toward the negative potential in association with the voltage-dependent modulation of the channels by cytosolic dialysis of alkaline phosphatase in beta-cells. The modulation of Kv-channel current-voltage relations were also observed during and after glucose-stimulated electrical excitation. These results suggest that the cellular metabolism including MgATP production and/or channel phosphorylation/dephosphorylation underlie the physiological modulation of Kv2.1 channels during glucose-induced insulin secretion.

    Regulation of delayed rectifier-type K+ channels (Kv-channels) by glucose was studied in rat pancreatic β-cells. The Kv-channel current was increased in amplitudes by increasing glucose concentration from 2.8 to 16.6 mM, while it was decreased by 2.8 mM glucose in a reversible manner (down-regulation) in both perforated and conventional whole-cell modes. The current was decreased by FCCP, intrapipette 0 mM ATP or AMPPNP. Glyceraldehyde, pyruvic acid, 2-ketoisocaproic acid, and 10 mM MgATP prevented the down-regulation induced by 2.8 mM or less glucose. The residual current after treatment with Kv2.1-specific blocker, guangxitoxin-1E, was unchanged by lowering or increasing glucose concentration. We conclude that glucose metabolism regulates Kv2.1 channels in rats β-cells via altering MgATP levels.

    Acetaminophen is a widely used antipyretic drug. We describe a 64-year-old Japanese woman who developed typical Churg-Strauss syndrome after frequent use of acetaminophen. Following the ingestion of acetaminophen, she exhibited various allergic reactions such as asthmatic attacks, pyrexia and petechiae on legs. In the lymphocyte transformation test, a positive reaction to acetaminophen was detected. A muscle biopsy revealed massive extravascular eosinophil infiltration and a necrotizing vasculitis. Hypersensitivity to acetaminophen may be implicated in the development of Churg-Strauss syndrome in this case.

    A 60-year-old woman with acute type adult T-cell leukemia (ATL) complicated with malignancy-associated hypercalcemia (MAH) was well controlled by peroral administration of sobuzoxane and etoposide supplemented in addition to weekly intravenous bisphosphonate injection after failing to get remission by a conventional protocol of intensive chemotherapy with granulocytic colony-stimulating factor (G-CSF). By this treatment at outpatient clinic, she could stay at home with psychological well being her life as long as six weeks until the very end stage of this fatal diseases. The combination of the two peroral drugs, sobuzoxane and etoposide may be one of considerable choice in ATL patients, when the conventional intensive chemotherapy with G-CSF is not effective enough.

    To explore the mechanism(s) by which phospholipase C (PLC)-gamma 2 participates in B cell Ag receptor (BCR) signaling, we have studied the function of PLC-gamma 2 mutants in B cells deficient in PLC-gamma 2. Mutation of the N-terminal Src homology 2 domain [SH2(N)] resulted in the complete loss of inositol 1,4,5-trisphosphate generation upon BCR engagement. A possible explanation for the SH2(N) requirement was provided by findings that this mutation abrogates the association of PLC-gamma 2 with an adaptor protein BLNK. Moreover, expression of a membrane-associated form (CD16/PLC-gamma 2) with SH2(N) mutation required coligation of BCR and CD16 for inositol 1,4,5-trisphosphate generation. Together, our results suggest a central role for the SH2(N) domain in directing PLC-gamma 2 into the close proximity of BCR signaling complex by its association with BLNK, whereby PLC-gamma 2 becomes tyrosine phosphorylated and thereby activated.

    Stimulation of B-cell antigen receptor (BCR) induces a rapid increase in cytoplasmic free calcium due to its release from intracellular stores and influx from the extracellular environment. Inositol 1,4,5-trisphosphate receptors (IP(3)Rs) are ligand-gated channels that release intracellular calcium stores in response to the second messenger, inositol 1,4,5-trisphosphate. Most hematopoietic cells, including B cells, express at least two of the three different types of IP3R. We demonstrate here that B cells in which a single type of IP3R has been deleted still mobilize calcium in response to BCR stimulation, whereas this calcium mobilization is abrogated hi B cells lacking all three types of IP3R. Calcium mobilization by a transfected G protein-coupled receptor (muscarinic M1 receptor) was also abolished in only triple-deficient cells, Capacitative Ca2+ entry, stimulated by thapsigargin, remains unaffected by loss of all three types of IP3R. These data establish that IP(3)Rs are essential and functionally redundant mediators for both BCR- and muscarinic receptor-induced calcium mobilization, but not for thapsigargin-induced Ca2+ influx. We further show that the BCR-induced apoptosis is significantly inhibited by loss of all three types of IP3R, suggesting an important role for Ca2+ in the process of apoptosis.

    CD45 is a tyrosine phosphatase that is required for normal B cell receptor (BCR)-mediated signaling. It has been shown that Src-family tyrosine kinases such as Lyn could be a potential substrate for CD45. In vitro studies indicate that activities of Src family tyrosine kinases are regulated by tyrosine phosphorylation; C-terminal phosphorylation is inhibitory, and autophosphorylation is stimulatory. We report here that both autophosphorylation and C-terminal negative regulatory tyrosines of Lyn were hyperphosphorylated in CD45-deficient DT40 B cells, In this mutant cell, BCR-induced protein-tyrosine phosphorylation and calcium mobilization were severely compromised, as seen in Lyn-deficient cells. Consistent with this observation, Lyn activation upon receptor ligation was profoundly decreased in CD45-deficient cells. Taken together, our results suggest that dephosphorylation of tyrosine residues at both autophosphorylation and negative regulatory sites is mediated by CD45 in vivo, and that dephosphorylation of C-terminal tyrosine is a prerequisite for participation of Lyn in BCR signaling.

    We studied the antioxidant effects of nine calcium antagonists (nisoldipine, benidipine, nilvadipine, felodipine, nicardipine, nitrendipine, nifedipine, verapamil, and diltiazem) by means of rat myocardial membrane lipid peroxidation with a nonenzymatic active oxygen-generating system (DHF/FeCl3-ADP). The order of antioxidant potency of these agents was nilvadipine > nisoldipine > felodipine > nicardipine > verapamil > benidipine. Their IC50 values (microM) were 25.1, 28.2, 42.0, 150.0, 266.1, and 420.0, respectively. In contrast, nitrendipine, nifedipine, and diltiazem had little inhibitory effect on lipid peroxidation. These six calcium antagonists could be divided into four types on the basis of their antioxidant mechanisms. Nilvadipine, nisoldipine, and verapamil, which showed antioxidant effects both before and after the addition of active oxygen, and reduced the dihydroxyfumarate (DHF) auto-oxidation rate, were chain-breaking and preventive antioxidants. Felodipine, which showed antioxidant effects both before and after exposure to active oxygen and increased the DHF auto-oxidation rate, was only a chain-breaking antioxidant. Nicardipine, which showed an antioxidant effect only before exposure to active oxygen and reduced the DHF auto-oxidation rate, was mainly a preventive antioxidant. Benidipine, which showed an antioxidant effect only before exposure to active oxygen and had no appreciable effect on the DHF auto-oxidation rate, could interrupt the chain reaction of lipid peroxidation at the initial step alone. Although these results suggest that the antioxidant properties of some calcium antagonists may be beneficial clinically in protecting against cellular damage caused by lipid peroxidation, further studies are required to establish the antioxidant effects of these agents in vivo.

    Both the production of active oxygen species and cellular damage due to concurrent lipid peroxidation are believed to be important factors in the pathogenesis of cardiovascular diseases and the ageing process. Since cardiovascular drugs are often administered over a long term, it might be advantageous if they reduced lipid peroxidation. There have been conflicting reports concerning the antiperoxidant effect of nifedipine. Therefore, we investigated whether nifedipine could inhibit lipid peroxidation in a nonenzymatic active oxygen-generating system, utilizing rat crude myocardial membranes, and compared its effect with those of propranolol, nisoldipine, and diltiazem. Nifedipine and diltiazem had no inhibitory effects on the lipid peroxidation of myocardial membranes. In contrast, nisoldipine and propranolol had a concentration-dependent antiperoxidant effect, with IC50 values of 28.2 and 50.1 mu M, respectively. In addition, nisoldipine appeared to possess dual antiperoxidant mechanisms, involving both preventive and chain-breaking properties.

    A 65 year-old female case of paratracheal cavernous hemangioma in the mediastinum was reported. She had suffered from hoarseness repeatedly for 3 years. Bronchofiberscopy disclosed a lusterless and erosive mucosa, loss of folds with bleeding tendency from below the vocal cord to the left main bronchus. A gray coarse nodule was located in the upper trachea below the vocal cord. These findings raised the very strong suspicion of primary malignant tracheal tumor or malignant invasion from the mediastinum. CT scan demonstrated a paratracheal mass with a calcification nodule. Bronchioarteriography showed increased vascularity and pooling of the contrast media along the trachea. No malignant cells were found in several cytological examinations of sputum. A biopsy of the tracheal mucosa displayed metaplastic changes. Mediastinoscopy and open biopsy were performed. Fat-like shrunk tissue with a strong bleeding tendency surrounded the trachea, and the tissue could be removed easily from the trachea. Microscopically the tissue consisted of wide cavernous spaces with a monomorph endthelial lining. This case was diagnosed as mediastinal cavernous hemangioma. Cavernous hemangioma is rare with a low incidence of approximately 1-1.5% of all mediastinal tumors.

    目的 壊死性筋膜炎を早期に診断し、進展を防ぐ可能性を模索するために、当科で経験した壊死性軟部組織感染症について臨床的に検討した。対象 2001年から当科で経験した壊死性皮膚軟部組織感染症18例(壊死性筋膜炎13例、壊死性蜂窩織炎5例)で男14例、女4例である。年齢は41〜91歳で、平均61.3歳であった。結果 部位 深頸部感染症および上腕、臀部の各1例を除き、15例が下肢病変であった。基礎疾患 糖尿病11例のほか、肝硬変2例、腎不全と咽頭癌放射線治療中の発症1例、下肢の慢性リンパ浮腫、骨折の既往、直腸癌穿孔も各1例にみられた。誘因 打撲に続発したもの2例、足背のBowen病術後にsurgical site infectionとして発症した例もみられた。検出菌 溶蓮菌11例(A群6例)、黄色ブドウ球菌5例(MRSA3例)、緑膿菌1例、大腸菌1例、クロストリジウム1例、陰性2例であった。混合感染は4例のみであった。手術 壊死性筋膜炎13例のうち、7例は全身麻酔でデブリードマンを施行したが、4例は局所麻酔でデブリードマンを行い、抗生物質の全身投与により感染症を治癒ないしコントロールさせることができた。合併症 DICを起こした例は4例、肝不全3例、腎不全1例であった。腸腰筋膿瘍、縦隔膿瘍を合併した例が各1例にみられた。予後 死亡例は2例(11%)で、急速な進行と全身状態からデブリードマンができなかった。大腿部切断は1例、足切断は1例、再発例は2例で1例は下腿の切断を行い救命し得た。考察 壊死性筋膜炎において、皮膚の水疱、血疱、壊死を呈し、急速に進行して多臓器不全に陥る劇症例の診断は皮膚外科医にとって困難ではない。しかし、急性ないし亜急性に経過する非劇症例では、実際上、蜂窩織炎との鑑別がしばしば困難である。したがって、壊死性軟部組織感染症を疑ったら、試験切開、生検をためらわないことが重要である。切開時の出血の有無、滲出液や脂肪織の状態を観察し、フィンガーテストを行う必要がある。壊死性筋膜炎の可能性があれば、広範囲のデブリードマンを行わなくてはならない。また、非劇症例で範囲の狭い場合は宿主の免疫状態にもよるが、早期に診断をすれば局所麻酔下での生検、試験切開と抗生物質で炎症を鎮静化できる例もあると思われた。(著者抄録)
