    Objective To manage patients with viral hepatitis, it is important to screen for hepatitis, conduct a comprehensive examination if such screening is positive, administer antiviral treatment, and conduct surveillance for hepatocellular carcinoma (HCC). The proper execution of this strategy is expected to effectively reduce the number of deaths from viral hepatitis. Such an "optimal" follow-up for HCC surveillance is therefore important. This study aimed to determine the benefits of performing an optimal follow-up of patients with viral hepatitis.

    Methods The subjects were infected with the hepatitis virus and were initially diagnosed with or treated for HCC from 2004-2012. We retrospectively analyzed the history of a patient's current illness using the hospital discharge summary. To minimize any lead-time bias, we calculated the corrected survival for patients who received an optimal follow-up.

    Results Of 333 patients, 107 (32.1%) did not receive an optimal follow-up and thus had low cumulative survival rates in comparison to those who did. The median corrected survival was 51.5 months for patients with an optimal follow-up compared with 31.4 months for those without (p=0.011). A multivariate analysis revealed that AFP <35 [odds ratio (OR), 2.054], Child-Pugh A (OR, 2.488), and an optimal follow-up (OR, 4.539) were independent factors associated with the detection of early-stage HCC. Age (OR, 0.939), tumor stage I/II (OR, 6.918), and an optimal follow-up (OR, 3.213) were found to be independent factors associated with receiving curative treatment.

    Conclusion An optimal follow-up of patients with viral hepatitis independently increased the detection of early-stage HCC and the administration of curative treatment. Patients with an optimal follow-up survived longer than those without.

    Objective Tolvaptan, an oral selective V2-receptor antagonist, is a water diuretic that ameliorates fluid retention with a lower risk of a worsening renal function than conventional loop diuretics. Although loop diuretics predominantly decrease extracellular water (ECW) compared with intracellular water (ICW), the effect of tolvaptan on fluid distribution remains unclear. We therefore examined how tolvaptan changes ICW and ECW in accordance with the renal function.

    Methods Six advanced chronic kidney disease patients (stage 4 or 5) with fluid retention were enrolled in this study. Tolvaptan (7.5 mg/day) added to conventional diuretic treatment was administered to remove fluid retention. The fluid volume was measured using a bioimpedance analysis device before (day 0) and after (day 5 or 6) tolvaptan treatment.

    Results Body weight decreased by 2.6%±1.3% (64.4±6.5 vs. 62.8±6.3 kg, p=0.06), and urine volume increased by 54.8%±23.9% (1,215±169 vs. 1,709±137 mL/day, p=0.03) between before and after tolvaptan treatment. Tolvaptan significantly decreased ICW (6.5%±1.5%, p=0.01) and ECW (7.5%±1.4%, p=0.02), which had similar reduction rates (p=0.32). The estimated glomerular filtration rate remained unchanged during the treatment (14.6±2.8 vs. 14.9±2.7 mL/min/1.732 m, p=0.35).

    Conclusion Tolvaptan ameliorates body fluid retention, and induces an equivalent reduction rate of ICW and ECW without a worsening renal function. Tolvaptan is a novel water diuretic that has a different effect on fluid distribution compared with conventional loop diuretics.

    Objective Parkinson's disease (PD) is characterized by the progressive degeneration of the nigrostriatal dopaminergic neurons. Rotigotine is a non-ergot dopamine receptor agonist (DA). Its transdermal patch maintains the effective concentrations for 24 hours. Freezing of gait (FOG) is a common and devastating symptom in PD patients. Little is known about therapeutic effects of rotigotine on FOG in PD patients. Herein we compared how three non-ergot DAs of rotigotine, pramipexole LA and ropinirole CR influence FOG, besides classical motor deficits in PD patients.

    Methods Rotigotine (maintenance doses of 9-27 mg/day) was administered in 51 patients, 36 patients received pramipexole LA (1.5-4.5 mg/day) and 35 patients received ropinirole CR (8-16 mg/day). The Unified PD Rating Scale (UPDRS) parts I-IV, FOG questionnaire (16 items) and wearing off time were examined from baseline to 7 months after DA administration. UPDRS parts I-IV were evaluated during on time and FOG was recorded during off time if patients experienced wearing off.

    Results A total of 111 patients completed the study. UPDRS parts II-III scores and wearing off time were significantly reduced after each DA treatment compared to baseline. FOG was found in 54 patients (49%). Most patients developed FOG during off time only. FOG scores were significantly decreased at 2 months after rotigotine treatment whereas pramipexole LA and ropinirole treatment did not alter FOG scores.

    Conclusion The present study indicates that transdermal patch of rotigotine attenuated the FOG off time. The similar binding affinities to dopamine receptors between rotigotine and dopamine, and 24 hours steady hemodynamics could contribute to the therapeutic mechanism of rotigotine on FOG in PD patients with wearing off.

    Objective In patients demonstrating dementia with Lewy bodies (DLB), pneumonia is a common complication. However, the prognostic factors for the survival time in DLB with pneumonia have not been investigated by autopsy in patients with neuropathologically confirmed DLB.

    Methods We conducted a retrospective study of the medical and autopsy reports of 42 patients admitted to a Japanese hospital between 2005 and 2014. The patients were neuropathologically diagnosed as having DLB by post-mortem examinations. We analyzed the effects of various factors on the time from DLB onset to death.

    Results Thirty-nine of the 42 patients with DLB (92.9%) developed pneumonia during hospitalization. The median age at DLB onset was 78 years and the median time from DLB onset to death was 8 years. The Cox proportional hazard model demonstrated cerebral infarction [Hazard Ratio (HR), 2.36 (95% CI 1.12-4.96), p=0.023], muscle weakness [HR, 2.04 (0.95-4.39), p=0.067], male sex [HR, 2.84 (1.24-6.50), p=0.014], and age at onset (≥78 years.) [HR, 4.71 (1.82-12.18), p=0.001] to be prognostic factors for a shorter time from DLB onset to death.

    Conclusion Careful treatment of cerebral infarction and muscle weakness of the lower extremities is crucial for DLB patients with pneumonia, especially for those over 78 years of age, in order to maximize the patients' life expectancies.

    Objective Our objective was to examine the safety and effects of therapy with biologics on the prognosis of rheumatoid arthritis (RA) patients with reactive amyloid A (AA) amyloidosis on hemodialysis (HD).

    Methods Twenty-eight patients with an established diagnosis of reactive AA amyloidosis participated in the study. The survival was calculated from the date of HD initiation until the time of death, or up to end of June 2015 for the patients who were still alive. HD initiation was according to the program of HD initiation for systemic amyloidosis patients associated with RA.

    Results Ten patients had been treated with biologics before HD initiation for a mean of 28.2 months (biologic group), while 18 had not (non-biologic group). HD was initiated in patients with similar characteristics except for the tender joint count, swollen joint count, and disease activity score (DAS)28-C-reactive protein (CRP). History of biologics showed that etanercept was frequently used for 8 patients as the first biologic. There was no significant difference in the mortality rate according to a Kaplan-Meier analysis (p=0.939) and or associated risk of death in an age-adjusted Cox proportional hazards model (p=0.758) between both groups. Infections were significantly more frequent causes of death in the biologic group than in the non-biologic group (p=0.021). However, treatment with biologics improved the DAS28-CRP score (p=0.004).

    Conclusion Under the limited conditions of AA amyloidosis treated with HD, the use of biologics might affect infection and thus may not improve the prognosis. Strict infection control is necessary for the use of biologics with HD to improve the prognosis.

    Objective It has been increasingly recognized in various clinical areas that self-efficacy promotes the level of competence in patients. The validity, applicability and potential usefulness of a new, simple model for assessing self-efficacy in the elderly with special reference to frailty were investigated for improving elderly patients' accomplishments.

    Methods The subjects of the present study comprised 257 elderly people who were members of the New Elder Citizen Movement in Japan and their mean age was 82.3±3.8 years. Interview materials including self-efficacy questionnaires were sent to all participants in advance and all other physical examinations were performed at the Life Planning Center Clinic.

    Results The internal consistency and close relation among a set of items used as a measure of self-efficacy were evaluated by Cronbach's alpha index, which was 0.79. Although no age-dependent difference was identified in either sex, gender-related differences in some factors were noted. Regarding several parametric parameters, Beck's inventory alone revealed a significant relationship to self-efficacy in both sexes. Additionally, non-parametric items such as stamina, power and memory were strongly correlated with self-efficacy in both sexes. Frailty showed a significant independent relationship with self-efficacy in a multiple linear regression model analysis and using Beck's inventory, stamina, power and memory were identified to be independent factors for self-efficacy.

    Conclusion The simple assessment of self-efficacy described in this study may be a useful tool for successful aging of elderly people.

    A 52-year-old woman presented with recurrent, severe abdominal pain. Laboratory tests and imaging were insignificant, and treatment for functional dyspepsia was ineffective. The poorly localized, dull, and severe abdominal pain, associated with anorexia, nausea, and vomiting, was consistent with abdominal migraine. The symptoms were relieved by loxoprofen and lomerizine, which are used in the treatment of migraine. We herein report a case of abdominal migraine in a middle-aged woman. Abdominal migraine should be considered as a cause of abdominal pain as it might easily be relieved by appropriate treatment.

    Ulcerative colitis (UC) is known to be associated with an increased risk of colorectal cancer. However, the occurrence of non-epithelial malignancies is uncommon. An elevated lesion in the descending colon was found in a 51-year-old woman with a 30-year history of UC. Despite tumor progression, repeated biopsies showed no cancerous findings. Because the lesion was highly suspected to be a malignant tumor, a partial colectomy was performed. The pathological diagnosis was leiomyosarcoma. Leiomyosarcoma of the gastrointestinal tract is rare, and this is only the third known case reported in patients with UC.

    A 75-year-old Japanese man was referred to our hospital to undergo the examination of an enlarged peripancreatic lymph node. Computed tomography (CT) showed a lymph node 47 mm in size that was located above the pancreas head and beneath the liver. Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) of the enlarged lymph node was performed, and an immunohistological examination of the sample confirmed a histological diagnosis of neuroendocrine carcinoma (NEC). The patient refused treatment with chemotherapy and instead chose to undergo observation. However, the lymph node the previously enlarged lymph node was not visible on CT at 12 months after the examination.

    Recent case reports have shown that hepatitis E virus (HEV) infection can cause chronic hepatitis in immunosuppressed or immunocompromised patients. A 37-year-old woman suffered from prolonged elevation of aminotransferases after chemotherapy for Burkitt's lymphoma and was diagnosed with chronic hepatitis E due to a transfusion during chemotherapy. After an 8-month administration of ribavirin, complete HEV clearance was not achieved, likely due to prolonged hypogammaglobulinemia. This case indicates that HEV infection should be ruled out during liver dysfunction in immunosuppressed or immunocompromised patients and suggests that an alternative therapeutic strategy for such patients will be needed.

    Eosinophilic myocarditis may be accompanied by Churg-Strauss syndrome (CSS). We report a case of CSS that was accompanied by myocardial changes in the early stage. A 71-year-old woman complained of mild chest pain at rest, but routine echocardiography did not reveal any endocardial abnormalities. Four months later, the patient was hospitalized due to congestive heart failure with neuropathy of both upper extremities. A diagnosis of eosinophilic myocarditis was made based on the patient's laboratory results and the presence of mural thrombus. This case illustrates that, although early eosinophilic myocarditis is an important differential diagnosis in patients with chest pain, it may be difficult to identify in without an apparent mural thrombus.

    Atrioventricular (AV) block and pseudoaneurysm of the mitral-aortic intervalvular fibrosa (P-MAIVF) are rare complications of infective endocarditis (IE). A 72-year-old man with severe aortic stenosis was hospitalized due to IE. After admission, intermittent AV block and P-MAIVF were noted. Interestingly, an accelerated junctional rhythm was observed during the process of AV block resolution. Elective surgery, which included patch closure of the fistula and replacement of the aortic valve, was successfully performed. The patient has remained in good condition without the recurrence of AV block. This case report describes a rare comorbidity of AV block and P-MAIVF in a patient with aortic valve IE.

We herein report the case of a 50-year-old woman who developed NS 94 days after UBT. She fell into oliguria and required dialysis. A kidney biopsy revealed focal and segmental glomerulosclerosis. Although glucocorticoid monotherapy did not improve her condition, the addition of low-density lipoprotein (LDL) apheresis resulted in remission of NS, a drastic improvement in her renal function, and withdrawal from dialysis. To the best of our knowledge, this is the first report of UBT-associated NS treated with LDL apheresis.

    A 30-year-old woman with myelodysplastic syndrome underwent allogeneic hematopoietic stem cell transplantation (HSCT) derived from her HLA-matched sister six years previously. She received preconditioning total body irradiation with renal shielding and was subsequently administered cyclosporin A (CyA) as prophylaxis against graft-versus-host disease (GVHD). Four months after HSCT, asymptomatic proteinuria and glomerular hematuria developed during CyA tapering without obvious extrarenal involvements of GVHD, and persisted for six years. A renal biopsy revealed endothelial injury in the glomeruli, and the deposition of C4d was detected diffusely on glomerular capillaries and focally on peritubular capillaries, suggesting that nephropathy involved antibody- or complement-associated immune reactions.

    We herein report a novel mutation in a Japanese family with an X-linked Alport syndrome (AS) mutation in COL4A5. Patient 1 was a 2-year-old Japanese girl. She and her mother (patient 2) had a history of proteinuria and hematuria without renal dysfunction, deafness, or ocular abnormalities. Pathological findings were consistent with AS, and a genetic analysis revealed that both patients had a heterozygous mutation (c.2767G>C) in exon 32. In summary, the identification of mutations and characteristic pathological findings was useful in making a diagnosis of AS. For a close long-term follow-up, the early detection and treatment of women with X-linked AS are important.

    We herein report the first case of pulmonary metastasis with lepidic growth that originated from cholangiocarcinoma. A 77-year-old man was admitted to our hospital due to exertional dyspnea and liver dysfunction. Computed tomography showed widespread infiltration and a ground-glass opacity in the lung and dilation of the intrahepatic bile duct. The pulmonary lesion progressed rapidly, and the patient died of respiratory failure. Cholangiocarcinoma and lepidic pulmonary metastasis were pathologically diagnosed by an autopsy. Lepidic pulmonary growth is an atypical pattern of metastasis, and immunopathological staining is useful to distinguish pulmonary metastasis from extrapulmonary cancer and primary pulmonary adenocarcinoma.

    Thrombocytopenia, anasarca, myelofibrosis, renal dysfunction and organomegaly (TAFRO) syndrome is a variant of Castleman's disease recently identified in Japan. A 73-year-old man was diagnosed with TAFRO syndrome according to clinical findings, and his symptoms improved after corticosteroid therapy. Ten months later, lymphadenopathy worsened during tapering of corticosteroids. Histological findings of abdominal lymph nodes showed diffuse large B-cell lymphoma. After 6 cycles of R-CHOP therapy, he has remained in sustained complete remission. This is a rare case of the development of malignant lymphoma during the treatment of TAFRO syndrome, which suggests an association between diffuse large B-cell lymphoma and TAFRO syndrome.

    We herein report three ischemic stroke patients who underwent emergency carotid artery stenting after receiving intravenous tissue plasminogen activator (t-PA) treatment. All patients received antiplatelet medications immediately before stent placement for loading as well as dual antiplatelet therapy after stenting. Under high-dose and dual antiplatelet therapy, none of the three patients showed symptomatic intracranial hemorrhaging. However, one case showed reocclusion of the placed stent after acute thrombosis. As a result, new treatment strategies for the use of antiplatelet agents during emergency stent placement must be developed, particularly for patients who have received intravenous t-PA therapy.

    A 37-year-old man was hospitalized for an evaluation of acute bilateral multiple subcortical infarcts. There were no specific signal abnormalities in the temporal pole or external capsule. An abdominal skin biopsy showed granular, electron-dense, osmiophilic material (GOM) in the smooth muscle cells on electron microscopy. A direct sequencing analysis of NOTCH3 revealed a heterozygous c.986G>A substitution in exon 6, resulting in a Cys329Tyr amino acid replacement. According to these findings, the patient was diagnosed with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencehalopathy (CADASIL). Thus, early phases of CADASIL can present as acute bilateral multiple subcortical infarcts without a characteristic temporal pole or any external capsule lesions.

However, he experienced a relapse 16 months later during retreatment with infliximab, revealing an interesting clinical course contradicting retreatment. This case also represents the first case of relapsed pulmonary cryptococcosis suspected during treatment with a biologic agent. Both of these aspects generated important clinical questions about the length of pulmonary cryptococcosis treatment and the necessity of introducing a second prophylaxis for such patients.

HIV-associated cholangiopathy remains important as a differential diagnosis of bile duct disorders, although it is considered to be a rare disease in the era of cART. Magnetic resonance cholangiopancreatography could thus be a powerful tool for the diagnosis and follow-up of this disease.

    We describe a patient with hereditary angioedema type I. The patient had experienced recurrent abdominal pain around the time of her menstrual period for 13 years. A laboratory examination showed reduced functional and antigenic levels of C4 and C1 inhibitor (C1-INH). To establish a diagnosis, we carried out a DNA analysis of the patient's C1-INH gene. We determined that the patient was heterozygous for a single base pair transposition of T to C at nucleotide 4429 in exon 4, which had not been reported in the literature. As the patient had no family history of hereditary diseases, it was considered to be a de novo mutation.

Despite systemic supportive treatments, the catatonic symptoms preceding autonomic symptoms persisted. The symptoms improved after lorazepam administration, leading to a retrospective diagnosis of malignant catatonia. Catatonia is thought to be caused by a dysfunction of ganmma-aminobutyric acid type A receptors in the cortico-cortical networks of the frontal lobes, which causes hypoactivity of the dopaminergic transmission in the subcortical areas. Identifying the catatonic symptoms preceding autonomic symptoms could aid in distinguishing malignant catatonia from NMS.
