Abstract
We present 3 cases of ocular syphilis in patients who had been newly diagnosed as having HIV. All the patients had only complained of ophthalmologic symptoms at the time of their initial visit. Treatment with penicillin was successful, resulting in no significant sequelae. Ocular syphilis may lead to reduced visual acuity or even blindness if left untreated. However, the diagnosis may be challenging, since patients may lack symptoms that are commonly observed in cases with primary and secondary syphilis. Considering the recent increase in the number of syphilis patients, clinicians should be aware of ocular syphilis and should have a high index of suspicion for syphilis in any patient at risk so as to ensure a prompt diagnosis.

Abstract
A 64-year-old man with advanced gastric cancer presented with chief complaints of chest pain. His preoperative blood examination revealed positive results for serum HIV-antibody. His HIV-RNA level was 1.0×10 / 5 copies/mL, and his CD4lymphocyte count was 491 cell/mL; the patient was diagnosed with advanced gastric cancer and HIV infection. Distal gastrectomy with D2 lymphadenectomy and Roux-en-Y reconstruction were performed for treatment of the gastric cancer. Pathological examination revealed T3(SS)N3aM0, Stage III C cancer. After surgery, the patient was administered S-1 monotherapy as adjuvant treatment with antiretroviral therapy including tenofovir/emtricitabine and raltegravir. He completed 8 courses of S- 1 chemotherapy with no adverse events, such as a decrease in the CD4lymphocyte count or an increase in the HIV-RNA level. This patient with gastric cancer and HIV infection was safely treated using both antiretroviral therapy and chemotherapy owing to treatment intervention by chemotherapy and infectious diseases specialists.

Abstract
We herein report the case of a 25-year-old man who was referred to our hospital due to acute cytomegalovirus (CMV) colitis. The initial blood tests showed that the patient had concurrent primary human immunodeficiency virus (HIV) infection and severe thrombocytopenia. Raltegravir-based antiretroviral therapy (ART) was initiated without the use of ganciclovir or corticosteroids and resulted in a rapid clinical improvement. Platelet transfusions were only necessary for a short period, and subsequent colonoscopy revealed a completely healed ulcer. This case implies that ART alone could be effective for treating severe thrombocytopenia during primary HIV and CMV coinfection.

Abstract
We herein report a case of laryngeal Kaposi's sarcoma (KS) complicated by immune reconstitution inflammatory syndrome in a human immunodeficiency virus (HIV)-infected patient. The patient initially presented with KS involving the larynx, which was successfully treated with pegylated liposomal doxorubicin (PLD) and antiretroviral therapy (ART). PLD was discontinued after 2 courses because of a marked clinical improvement; however, the patient experienced progressive odynophagia and dyspnea 2 months after the initiation of ART. Laryngoscopy revealed a severely swollen, inflamed epiglottis. The readministration of PLD was successful, and the patient was thereafter discharged without any subsequent complications.

Abstract
We herein report a 52-year-old man infected with human immunodeficiency virus (HIV) who was referred to our hospital due to the development of severe neurocognitive disorders and bilateral leukoencephalopathy. He has been treated with antiretroviral agents for 17 years, but low-level viremia has been detected consistently prior to admission. Drug resistant testing of the serum and the cerebrospinal fluid (CSF) both demonstrated a M184V mutation. A brain biopsy revealed perivascular CD8(+) T-lymphocyte infiltration, leading to the diagnosis of CD8 encephalitis. The clinical symptoms improved drastically after changing to a nucleoside reverse transcriptase inhibitor sparing regimen, which subsequently decreased the HIV viral load to an undetectable level in both the serum and CSF.

Abstract
OBJECTIVE Assessing the degree of problems related to drug abuse is important in each treatment setting. The Drug Abuse Screening Test-20 (DAST-20) is a brief, simple 20-item instrument to measure the degree of problems related to drug use. The objective of the present study is to examine the reliability and validity of the Japanese version of the DAST-20. METHODS We translated the DAST-20 into Japanese using back translation. The anonymous self-administered questionnaire was completed by 310 drug users at the Drug Addiction Rehabilitation Centers (DARC group, n = 113) and at HIV/AIDS regional hospitals (HIV group, n = 197) in Japan. RESULTS The average DAST-20 score was 7.6 (DARC group = 14.7, HIV group = 2.8). Each item score was highly correlated with the total score (r = 0.45-0.88). A high internal consistency (Cronbach's α = 0.95) was observed (men = 0.95, women = 0.84). Overall test-retest reliability was 0.86 (men = 0.85, women = 0.90). The total DAST-20 score was strongly positively correlated with the Severity of Dependence Scale-J score (r = 0.85), but moderately positively correlated with the Alcohol Use Disorders Identification Test score (r = 0.41). In addition, confirmatory factor analysis indicated an acceptable fit to the data (goodness-of-fit index [GFI] = 0.893, adjusted goodness-of-fit index [AGFI] = 0.854, comparative fit index [CFI] = 0.948, root mean square residual [RMR] = 0.008, root mean square error of approximation [RMSEA] = 0.073). CONCLUSION Our results clearly suggest that the Japanese version of the DAST-20 has sufficient internal consistency and acceptable levels of concurrent validity and construct validity.

Abstract
Atazanavir is commonly used as one of the key drugs in combination antiretroviral therapy for human immunodeficiency virus (HIV). However, atazanavir has the potential to yield its crystalline precipitation in urine and renal interstitial tissues, leading to crystalluria, urolithiasis, acute kidney injury (AKI) or chronic kidney disease (CKD). In epidemiological studies, atazanavir/ritonavir alone or in combination with tenofovir has been associated with increased risk of progression to CKD. However, renal biopsies were not provided in these studies. Case reports showing an association between atazanavir use and tubulointerstitial nephritis among HIV-infected individuals provide clues as to the potential causes of atazanavir nephrotoxicity. We now review atazanavir-related kidney disease including urolithiasis, renal dysfunction and interstitial nephritis and illustrate the review with a further case of atazanavir-associated kidney injury with sequential renal biopsies. There are two forms of atazanavir-associated tubulointerstitial nephritis: acute tubulointerstitial nephritis that may develop AKI rapidly (in weeks) after initiation of atazanavir, and chronic tubulointerstitial nephritis that may develop progressive CKD slowly (in years) with granuloma and intrarenal precipitation of atazanavir crystals as well as crystalluria. Caution should be exercised when prescribing atazanavir to patients at high risk of CKD, and therapy should be reevaluated if renal function deteriorates, especially associated with crystalluria and hematuria.

Abstract
With the advent of antiretroviral therapy, lung cancer has become a crucial health problem among individuals living with human immunodeficiency virus (HIV). In East Asian populations, the frequency of lung cancer patients harboring epidermal growth factor receptor (EGFR) mutations is greater than in other populations. Herein, we present two cases of advanced non-small cell lung cancer with EGFR mutations in patients treated with EGFR-tyrosine kinase inhibitors. Both patients were male, 67 and 59 years of age, with known HIV infection and immunologically stable disease with antiretroviral therapy. Case 1 was treated with erlotinib for recurrent adenocarcinoma metastasizing to the liver and brain harboring EGFR mutation in exon 21 L858R. The duration of treatment efficacy was 9.7 months. Case 2 had an EGFR mutation exon 19 in-frame deletion with bone metastasis and was treated with gefitinib for 22.1 months in combination with antiretroviral therapy. These advanced lung cancer patients living with HIV with EGFR mutations demonstrate the promising effectiveness and safety of EGFR-tyrosine kinase inhibitors concomitant with antiretroviral therapy for an extended period.

Abstract
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.

Abstract
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 patient's 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.

Abstract
We report a case of a 60-year-old man infected with human immunodeficiency virus (HIV) who was transferred to our hospital for management of multiple non-healing, painful ulcers on the lower extremities. The histological findings of the biopsy specimen were compatible with the diagnosis of pyoderma gangrenosum (PG). An association between HIV infection and the development of PG was considered after a thorough investigation. Antiretroviral therapy without the use of adjunctive immunosuppressive agents resulted in clinical improvement. Our case implies that antiretroviral therapy alone could heal PG in untreated HIV-infected patients.

Abstract
A 19-year-old Filipino man was admitted to our hospital because of persisting fever and back pain. He had recognized his symptoms 6 months previously, but a definite diagnosis was not made. Image testing demonstrated a compressed fracture of the thoracic vertebrae accompanied with a perivertebral abscess. A biopsy specimen revealed granuloma compatible with tuberculosis (TB). Anti-TB drugs were initiated, and his clinical symptoms steadily improved. However, he developed neuropathic symptoms due to exacerbation of the abscess two months after starting the anti-TB drugs. An immediate laminectomy was performed resulting in symptom relief; however severe kyphosis remained. Polymerase chain reaction testing of the abscess collected during the operation was positive for Mycobacterium tuberculosis, confirming the diagnosis of spinal TB. The diagnosis of spinal TB has been a challenge world-wide. Clinicians should be aware of the demographic background as well as the clinical and laboratory features of spinal tuberculosis, facilitating earlier diagnosis.

Abstract
BACKGROUND In 2012, the number of rubella cases sharply increased in Japan. It continued to rise in 2013. Between October 2012 and May 2013, 10 cases of congenital rubella syndrome (CRS) were reported nationwide. This current rubella outbreak comprised mainly males who were between 20 to 39 years of age, and had not received the rubella vaccine. Data have been lacking on the clinical characteristics of adults infected with the rubella virus. METHODS Using medical charts, we collected data from 27 patients who were diagnosed with clinically or laboratory-confirmed rubella infection at Tokyo Metropolitan Komagome Hospital from January 2012 to April 2013. RESULTS Of the 27 patients studied, their median age was 34.5 years and 70.4% were male between 21-56 years of age. For the 11 cases with known vaccination status, 9 (81.8%) occurred in persons who had not received a rubella vaccine. A total of 33.3% of the patients were hospitalized, due to persistent fever, poor oral intake, or dehydration. Major clinical symptoms were fever (96.3% of cases), lymphadenopathy (92.6%), rash (85.2%), conjunctivitis (77.8%), and headache (63.0%). The mean duration of fever was 5 days (range, 3-9). The exanthema consisted of punctate, pink maculopapules; however, the rash became confluent in 37.0%, and pigmented in 18.5% of the patients. Initial laboratory data were as follows:white cells, 3,800/microL (range: 2,000-8,300); platelets, 129,000/microL (range, 63,000 - 230,000); aspartate aminotransferase, 27IU/L (range, 16 - 49); lactase dehydrogenase, 279IU/L (range, 168-440) [all described in medians]. Rubella-specific immunoglobulin M antibodies from the serum sample obtained at the initial visit were detected in 17 cases (65.4%). Likewise, measles-specific immunoglobulin M antibodies were detected in 7 cases (26.9%), all of which were false-positive. CONCLUSIONS The clinical characteristics of rubella in adults resembled measles in some part, which may cause difficulty for physicians to differentiate between the two diseases. Vaccinating rubella-susceptible individuals now is critical to interrupt rubella virus transmission, and to prevent further CRS cases.

Abstract
BACKGROUND The improved survival of subjects with human immunodeficiency virus (HIV) has been accompanied by an increased prevalence of chronic kidney disease (CKD). Epidemic of CKD among those with HIV has not yet been evaluated in multiple tertiary hospitals in Japan. METHODS A cross-sectional study was conducted in 2011 at Tokyo Metropolitan Komagome Hospital (TMKH) and Tokyo Medical University Hospital (TMUH). A total of 1482 HIV-infected subjects (1384 men, 98 female, mean age: 44.2 +/- 11.4 years old) were consecutively enrolled in the study. Random urine and blood samples were collected to study prevalence of CKD. CKD was diagnosed as a decrease in glomerular function and/or proteinuria and classified into 5 stages based on National Kidney Foundation guidelines. The estimated glomerular filtration rate based on serum creatinine was calculated using the 3-variable equation, constructed by the Japanese Society of Nephrology. Proteinuria was defined as > or = 1+ on urine dipstick examination. All electronic medical charts were reviewed to determine comorbidities, including hypertension and diabetes mellitus (DM). The proportion of subjects receiving tenofovir disoproxil fumarate (TDF) was investigated. Risk factors for CKD were determined using multivariate logistic regression analysis. RESULTS The mean CD4 cell count was 487 +/- 216/microL and 80.5% had undetectable HIV-RNA level in the combined cohort. Of the 90.2% of subjects taking antiretroviral agents, 61.5% was using TDF. The prevalence of overall CKD and CKD > or = stage 3 was 12.9% and 6.7%, respectively, both of which were nearly 3-fold higher in the TMKH cohort (p < .0001). Mean age and proportional prevalent hypertension and DM were significantly higher in the TKMH cohort than in the TMUH cohort. Multivariate analysis showed significant CKD to be associated with age > or =50 years (odds ratio [OR], 2.81), hypertension (OR, 3.04), and DM (OR, 2.05). CONCLUSIONS CKD prevalence was 12.9% among combined cohorts, but differed significantly between them. Differences in age distribution and the proportion of comorbidities, including hypertension and DM, are likely involved.

Abstract
BACKGROUND Human immunodeficiency virus (HIV)-infected patients are surviving longer since the advent of antiretroviral therapy. Therefore, more patients are developing non-AIDS-defining cancers which increasingly determine mortality. CASE REPORTS Here we present 2 cases of locally advanced non-small cell lung cancer treated initially with concomitant chemoradiotherapy and antiretroviral therapy. Both patients were male, ages 69 and 66, with known HIV infection and immunologically stable on antiretroviral therapy. Presenting symptoms included superior sulcus tumor with left arm immobility and sensory disturbance in case 1 and right lower bronchus constriction in case 2. Symptoms were controlled by chemoradiotherapy. CONCLUSION These cases illustrate that intensive anticancer therapy administered to the HIV-infected population can be tolerated even though these patients seem to be too fragile for both chemotherapy and radiotherapy, especially since the potential benefit remains uncertain. Recent improvements in chemoradiotherapy and supportive care have enhanced tolerance for such therapy.

Abstract
We report on a previously healthy 56-year-old woman who was referred to our hospital with fever and progressive left foot pain. She had been bitten by a cat 7 days previously, and cephalosporins had been prescribed for treatment. However, her clinical symptoms deteriorated, and physical examination on admission was compatible with necrotizing fasciitis. Treatment with ampicillin-sulbactam and clindamycin was initiated. In addition, immediate surgical debridement was performed, resulting in therapeutic success. Culture of the necrotizing tissue grew multiple organisms, including Pasteurella multocida and Bacteroides caccae. Administration of appropriate antibiotics after a cat bite is essential for the prevention of potentially fatal complications.

Abstract
BACKGROUND Living donor liver transplantation is widely performed in adult patients. One of the problems in this setting is a small-for-size graft, which results in dysfunction and poor prognosis of a transplantation. A right liver graft was devised to overcome this problem; furthermore, inclusion of the middle hepatic vein (MHV) has been suggested to greatly improve recipient outcomes. However, extended right hepatectomy involves a surgical risk for the living donor in terms of congestion of the left paramedian sector. The volume of the venoocclusive region of a living donor liver possibly varies depending on the collateral patterns of veins draining the cranial part of segment 4 (S4). PATIENTS AND METHODS We were analyzed the normal livers of 50 patients who underwent triphasic contrast-enhanced multidetector row computed tomography during preoperative and postoperative examinations. The patient pathologies consisted of gastric cancer (n = 25), colon cancer (n = 1), or renal cancer (n = 24). We calculated the volume of the entire liver as well as those of the right graft and left remnant lobes for comparison with the drainage volume of each hepatic vein and its branches. RESULTS On the basis of the anatomic venous drainage of the cranial part of S4 (V4sup), we classified hepatic veins as group A (n = 31), the V4sup joined the left hepatic vein or the MHV distal to the vein draining S8 area (MV8), or group B (n = 19), V4sup joined the MHV proximal to MV8. The mean volume of the congested area was 6.9% in group A and 15.9% in group B. The venoocclusive areas in the remnant livers were estimated to be larger in group B (P < .001). CONCLUSION The collateral pattern of V4sup and MV8 as well as preoperative volumetric analysis are important for graft selection to decide the line of transection.

Abstract
The case of a 66-year-old woman with untreated diabetes mellitus who was admitted to our hospital with a fever, hypotension and an altered mental status is herein reported. Computed tomography revealed bilateral emphysematous pyelonephritis along with a splenic abscess. Blood and urine cultures grew Escherichia coli. Treatment with systemic antibiotics combined with the insertion of percutaneous and renoureteral catheters was successful. The patient was discharged and completed treatment without developing any subsequent complications.

Abstract
We report on a 26-year-old Japanese man who was referred to our hospital because of anal pain and hematochezia. On admission, in addition to his gastrointestinal symptoms, a generalized maculopapular rash was observed, involving the palms of his hands and soles of his feet. His history and physical examination were compatible with syphilis, confirmed by a high syphilis titer on blood examination. Further tests revealed the presence of HIV infection, with a CD4 cell count of 227/microL. Colonoscopy demonstrated a deep ulcer in the lower rectum, although biopsy specimens did not reveal any syphilis spirochetes, or any other specific microorganisms. Intravenous penicillin G was initiated, resulting in a dramatic improvement of the ulcers along with the skin lesions confirming the diagnosis of syphilis proctitis. A rapid plasma reagin titer test performed 3 months after treatment demonstrated significant decrease, indicating successful treatment.
