    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.

    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.

    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.

    Acute pharyngitis is commonly encountered, but a definite etiological diagnosis is difficult. Although coinfection 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.

    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.

    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, and Pneumocystis jirovecii pneumonia. 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.
