    Background:HIV-associated neurocognitive disorders (HAND) have emerged as a problem among HIV-infected individuals in the era of antiretroviral therapy. However, there are insufficient data on HAND regarding its prevalence and clinical features in Japan. Methods:A test battery composed of eight neuropsycological tests proposed by the Ministry of Health,Labour and Welfare (MHLW test battery) was applied to assess 30 subjects at Tokyo Metropolitan Komagome Hospital. Among them, 5 subjects were excluded due to central nervous system complications. The background of each patient along with the results of head magnetic resonance imaging (MRI), cerebrospinal fluid (CSF) analysis and neuropsychological tests were compared to each HAND category. In addition, the clinical utility of a combination of neuropsychological tests as an abbreviated test battery of HAND was evaluated. Results:A total of 19 (76%) subjects were diagnosed as having a HAND. Among them, HIV-associated dementia, mild neurocognitive disorders and asymptomatic neurocognitive disorders were diagnosed in 7, 8,and 4 subjects, respectively. Neither the patientʼs background nor the results of the head MRI and CSF analysis showed relevance to disease severity. The conventional International HIV Dementia Scale with the Digit Symbol Substitute Test was capable of detecting 94.7%cases of HAND. Conclusions:Most HIV-infected subjects clinically suspected as having neurocognitive disorders were diagnosed as having a HAND. Neuropsychological tests of the MHLW test battery were in some part useful to diagnose HAND. However, more precise neuropsychological tests are warranted to screen and diagnose HAND, based on the current criteria.

    This is a report of an outbreak of Pneumococcal pneumonia among nursing home residents in Tokyo, 2009. A total of 15 cases were identified, and their sputum culture grew Streptococcus pneumoniae, all of which were confirmed as serotype 11A and ST116. This outbreak ended through the implementation of strict contact precautions, education regarding the standard precautions among the staff, administration of prophylactic antibiotics to other asymptomatic residents, and vaccination. The fact that many cases were unvaccinated in this outbreak implies the importance of vaccination against S. pneumoniae among nursing home residents.

    A 31-year-old Japanese female had stayed in Australia from January to May 2013. She presented with a sudden onset of left ankle and right knee arthralgia in March but neither fever nor rash was present. As her arthralgia persisted, she visited our hospital upon her return to Japan in May. When she came to our hospital, she complained of left ankle and right knee pain, but no arthritis findings. Laboratory findings were also within normal ranges. Ross River virus (RRV) antibody levels were examined as she was suspected of having contracted the disease in Australia. RRV IgG antibody and IgM antibody were positive, and the patient was confirmed as a case of acute RRV disease. RRV disease is endemic in Australia, but there are no prior reports of the disease in Japan. This is the first case of RRV disease confirmed in Japan. Typical symptoms of RRV disease include arthralgia, fever, and rash. Our patient had only arthralgia. With the increase in the number of travelers and length of stay in RRV endemic regions, health care providers need to consider the disease in their differential diagnosis, among returning travelers with arthralgia, fever, rash and a travel history to RRV-endemic regions.

    Mycoplasma pneumoniae is one of the common pathogens of the community-acquired pneumonia in adults and children. Macrolide antibiotics are considered to be the first-choicedrugforM. pneumoniae infections. However, macrolide-resistant M. pneumoniae was first detected from Japanese pediatric patients in 2000, and it has been increasing over the past decade. On the other hand, the Immunocard Mycoplasma IgM test is widely used as a rapid and easy diagnostic method for M. pneumoniae pneumonia, but false-positive or false-negative cases have been reported in adults. Therefore new methods have been developed recently. Using the LAMP assay, the results are available rapidly and accurately. We report herein on two cases of M. pneumoniae bronchopneumonia in which the LAMP assay was useful in the diagnosis and treatment.

    We report herein on a 20-year-old Japanese man who was referred to our hospital for fever and diarrhea after returning from Indonesia. On admission, his blood test was essentially normal, besides a slight elevation in inflammatory markers. After excluding malaria and dengue fever, empiric use of ceftriaxone was initiated for suspected enteric fever, which was unsuccessful. However, drastic clinical improvement was observed after initiation of minocycline. The polymerase chain reaction test for Rickettsia typhi was positive from serum samples on admission, confirming the diagnosis of murine typhus. Although rarely seen in Japan, clinicians should be aware of this disease when examining patients with fever coming back from murine typhus endemic areas.

    We report herein on a case of the primary intestinal tuberculosis in which small intestine perforation developed. A 60-year-old man with congestive heart failure developed fever and sudden onset of abdominal pain while he was in the hospital. Computed tomography of the abdomen showed a large amount of free-air and the thickening of a part of the ileum. Perforation of the gastrointestinal tract was diagnosed. The patient underwent emergency exploratory laparotomy and a partial resection of the ileum was performed. The presence of nodules in the ileum suggested possible tuberculosis of the intestine. Pathologically caseating epithelioid granulomas were noted and the diagnosis of tuberculosis of the ileum was made although microbiologically tuberculous bacilli were not documented. The patient was successfully treated with antituberculosis chemotherapy. Although intestinal tuberculosis is a rare cause of intestinal perforation, it is important to include intestinal tuberculosis as one of the cases.
