    Anorexia nervosa (AN) is often accompanied by numerous medical complications and mental disorders. There are few specialized AN facilities in Japan, resulting in the unmet medical needs of patients with AN. A 37-year-old Japanese woman was admitted to the hospital after experiencing a disturbance of consciousness. Her body mass index was 10.2 kg/m2. She developed the following serious medical concomitants associated with extremely severe AN: hypothermia, shock liver, refractory hypoglycemia, acute gastric mucosal bleeding, gelatinous marrow transformation, catheter-related bloodstream infection and infective endocarditis due to β-lactamase-negative Staphylococcus aureus, aspiration pneumonia, intracranial hemorrhage, candidemia, and osmotic demyelination syndrome in the pons, which led to a fatal condition that quickly worsened after we started treatment. The patient was able to overcome several serious concomitants and be discharged from the hospital after multidisciplinary treatment team care. AN is associated with increased rates of all-cause mortality. It is important to take an interdisciplinary approach with emergency physicians, intensivists, hematologists, gastroenterologists, psychiatrists, clinical psychologists, a nutrition support team with a nationally registered nutritionist and hospitalists, and hospitalization as required based on appropriate medical evaluation with good patient and family rapport. Furthermore, social and educational efforts aimed at preventing the development of AN are necessary.

    BACKGROUND/AIM: In prostate cancer, robotic total prostatectomy is a popular treatment modality. However, prostate-specific antigen (PSA) recurrence after prostate cancer surgery remains a concern. Salvage radiotherapy is commonly used to treat PSA recurrence, but the recurrence rate after salvage radiotherapy is high, highlighting the need for better predictive markers. This study aimed to retrospectively evaluate the association between cribriform pattern and PSA recurrence in patients receiving radiotherapy after radical prostatectomy. PATIENTS AND METHODS: Data of 50 patients who underwent radiotherapy after total prostatectomy between January 2010 and May 2020 were retrospectively evaluated. The median age was 67 years. Among these patients, two cases involved postoperative irradiation, while 48 cases involved salvage irradiation after postoperative PSA recurrence. The median time from surgery to PSA recurrence was 38.3 months. The median radiation dose was 64 Gy in 32 fractions. Three-dimensional conformal radiation therapy was administered in 38 cases and intensity-modulated radiation therapy was used in 12 cases. Combined hormone therapy was administered in 21 cases. PSA levels were measured every 3 months after treatment. Statistical analysis between groups was performed by a t-test. RESULTS: The median follow-up period after radiotherapy was 31 months. No local recurrences were observed at the prostate bed, and no deaths related to prostate cancer were recorded during follow-up. However, 18 patients (36.0%) had PSA recurrence. The PSA recurrence rate based on the cribriform pattern was 17.6% in the none to moderate group (34 patients) and 75.0% in the severe cribriform pattern group (16 patients). The PSA recurrence rate was significantly higher in patients with a severe invasive cribriform pattern (p=0.001). No significant differences were observed in other histopathological characteristics. CONCLUSION: The cribriform pattern in surgical pathology specimens was found to be a useful predictor of PSA recurrence after postoperative radiotherapy.

    Lymphomatoid granulomatosis (LYG) is a rare B cell lymphoproliferative disorder associated with Epstein-Barr virus infection. LYG diagnosis is often difficult because of non-specific and varied radiological and pathological findings. The lung is the most common organ of LYG occurrence, but extrapulmonary lesions involving the central nervous system, skin, kidneys and liver are observed. A surgical biopsy is often inevitable for LYG diagnosis.We encountered a man in his 50s who presented with progressive dyspnoea. Extrapulmonary lesions were not observed. Although he developed respiratory failure within a short period, a low dose of corticosteroid relieved his symptoms. Video-assisted thoracoscopic lung biopsy revealed grade 1 LYG. The patient was successfully treated with chemotherapy, including rituximab. Only a few cases of LYG with progressive respiratory failure are reported, and most have been diagnosed via autopsy. Our case highlights the importance of performing a surgical lung biopsy at the appropriate time to diagnose LYG.
