    Objective Diabetes is a negative predictor in coronary artery disease patients. Since the introduction of percutaneous coronary intervention (PCI), PCI has evolved through technological advances in devices, improvements in operators' techniques and the establishment of effective therapeutic protocols. The aim of this study is to examine the changes in the clinical outcomes following PCI in patients with diabetes.

    Methods We compared the clinical outcomes in patients with diabetes following PCI from 1984 to 2010 at Juntendo University over three eras (plain old balloon angioplasty (POBA)-, bare metal stents (BMS)- and drug-eluting stents (DES)-eras). The primary endpoint was a composite of all-cause mortality, non-fatal myocardial infarction, non-fatal stroke and repeat revascularization within 3 years after the index PCI.

    Results A total of 1,584 patients were examined. The baseline characteristics became unfavorable over time with regard to age, prevalence of hypertension, presentation with acute coronary syndrome and a reduced left ventricular ejection fraction. The administration of aspirin, statins and β-blockers increased over time. The event-free survival rate for the 3-year cardiovascular events was lower in the DES-era. The adjusted relative risk reduction for 3-year cardiovascular events was 46 % in the DES-era compared with the POBA-era.

    Conclusion The incidence of 3-year cardiovascular events decreased from 1984 to 2010 in patients with diabetes following PCI, despite the higher risk profiles in the DES-era.

    Objective The Nagasaki Kunchi Festival is one of the most famous festivals in Nagasaki. The bearers the floats that are used in this festival undergo long-term training for the performance. However, there have not been any studies on the effects of this training on the health of the float bearers.

    Methods Thirty-four men ranging in age from 20 to 49 years (mean age: 35.7±7.6 years) were included in the study. We examined the following parameters before and after the training: body weight (BW), body mass index (BMI), body fat percentage, muscle volume, systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse rate (PR), pulse pressure (PP), bearing power, arterial pressure volume index (API), and arterial velocity pulse index (AVI).

    Results For all participants, the BW, BMI, body fat percentage, and PR were significantly decreased, and the muscle volume and bearing power were significantly increased after the training; however, there were no significant changes in the SBP, DBP, PP, API, or AVI. In the participants with hypertension, in addition to decreases in BW, BMI, body fat percentage, PR, and PP, the SBP, DBP, and API were significantly decreased after the training.

    Conclusion Training for bearing a float during Nagasaki Kunchi effectively improved the body structure of all participants and reduced the BP and API in participants with hypertension.

    Objective The goal of the present study was to investigate the plasma hydrogen sulfide (H2S) levels in patients with type 2 diabetes, as the plasma H2S levels in Japanese patients with type 2 diabetes remain unclear.

    Methods The plasma H2S levels were measured in 154 outpatients with type 2 diabetes and 66 outpatients without diabetes. All blood samples were collected in the outpatient department from 09:00 to 10:00. The patients had fasted from 21:00 the previous evening and had not consumed alcohol or caffeine or smoked until sample collection. The plasma H2S levels were measured using the methylene blue assay. The plasma H2S levels were determined in triplicate, and the average concentrations were calculated against a calibration curve of sodium sulfide.

    Results The patients with type 2 diabetes showed a progressive reduction in the plasma H2S levels (45.1±15.5 μM versus 54.0±26.4 μM, p<0.05), which paralleled poor glycemic control. There was a significant correlation between a reduction in the plasma H2S levels and the HbA1c levels (β=-0.505, p<0.01), Furthermore, a reduction in the plasma H2S levels was found to be related to a history of cardiovascular diseases in patients with type 2 diabetes (39.9±13.8 μM versus 47.5±15.9 μM, p<0.01).

    Conclusion Collectively, the plasma H2S levels were reduced in patients with type 2 diabetes, which may have implications in the pathophysiology of cardiovascular disease in diabetic patients. The trial was registered with the University Hospital Medical Information Network (UMIN no. #000020549).

    Objective It is recommended that middle-aged and elderly individuals reduce their salt intake because of the high prevalence of hypertension. The consumption of miso soup is associated with salt intake, and the reduced consumption of miso soup has been recommended. Recent studies have demonstrated that the consumption of miso soup can attenuate an autonomic imbalance in animal models. However, it is unclear whether these results are applicable to humans. This study examined the cross-sectional association between the frequency of miso soup consumption and the blood pressure and heart rate of human subjects.

    Methods A total of 527 subjects of 50 to 81 years of age who participated in our hospital health examination were enrolled in the present study and divided into four groups based on the frequency of their miso soup consumption ([bowl(s) of miso soup/week] Group 1, <1; Group2, <4; Group3, <7; Group4, ≥7). The blood pressure levels and heart rates of the subjects in each group were compared. Furthermore, a multivariable analysis was performed to determine whether miso soup consumption was an independent factor affecting the incidence of hypertension or the heart rate.

    Results The frequency of miso soup consumption was not associated with blood pressure. The heart rate was, however, lower in the participants who reported a high frequency of miso soup consumption. A multivariable analysis revealed that the participants who reported a high frequency of miso soup consumption were more likely to have a lower heart rate, but that the consumption of miso soup was not associated with the incidence of hypertension.

    Conclusion These results indicate that miso soup consumption might decrease the heart rate, but not have a significant effect on the blood pressure of in middle-aged and elderly Japanese individuals.

    Objective This study was conducted to investigate whether the add-on treatment of allergic rhinitis (AR) based on the Self-assessment of Allergic Rhinitis and Asthma (SACRA) questionnaire for assessing AR control improves both AR and asthma control in asthmatic patients with AR.

    Methods This multi-center prospective study was performed in Nagano prefecture, Japan. Two hundred five asthmatic patients and 23 respiratory physicians participated in the study. We administered add-on AR treatments based on the results of the SACRA questionnaire. After the first SACRA questionnaire, 67 asthmatic patients agreed to receive an add-on AR treatment. Three months after the AR treatment, a secondary SACRA questionnaire, asthma control test (ACT), and pulmonary function tests were performed.

    Results After the add-on AR treatment, the visual analogue scales (VASs) for AR and asthma, as assessed by the SACRA questionnaire and ACT score, were significantly improved in the patients of the AR+ group. With regard to the pulmonary function tests, the percent predicted vital capacity, and percent predicted forced expiratory volume in one second were also significantly improved. Regardless of whether the patients had previously undergone leukotriene receptor antagonists (LTRA) treatment, the VASs for AR and asthma and the ACT score were significantly improved in the AR+ group. However, the vital capacity (VC), forced vital capacity (FVC) and forced expiratory volume (FEV1) were only significantly improved in the AR+ group that had previously undergone LTRA treatment.

    Conclusion SACRA questionnaire-based add-on AR treatment would be convenient for the detection of AR by respiratory physicians and would offer improved asthma control. This questionnaire can also be used to assess the therapeutic effects.

    We herein report two cases of drug-induced liver injury (DILI) due to mosapride. Case 1: A 78-year-old man was admitted with elevated transaminase levels. The cessation of mosapride led to the improvement of elevated liver enzyme levels. Case 2: A 54-year-old man was admitted with jaundice. Mosapride was discontinued immediately, and methylprednisolone was administered for acute liver failure. The patient's data showed improvement, and he was discharged on Day 32. In both cases, mosapride gave a positive response to a drug-induced lymphocyte stimulation test (DLST), and the patient's score based on the criteria for DILI was "highly probable".

    The clinical picture of IgG4-related disease (IgG4-RD) is diverse because various organs can be affected. We describe the case of a 56-year-old man with acute renal failure and tuberoinfundibular hypophysitis due to IgG4-RD. Steroid therapy lowered the serum IgG4 level and ameliorated renal dysfunction, bilateral hydronephrosis and retroperitoneal fibrosis. However, polyuria from post-obstructive diuresis and unmasked central diabetes insipidus ensued. The patient's polyuria continued despite the administration of a therapeutic dose of glucocorticoid; the patient's pituitary swelling and anterior pituitary dysfunction were partially ameliorated. The pituitary swelling recurred seven months later. In patients with IgG4-RD, the manifestation of polyuria after steroid therapy should prompt suspicion of post-obstructive diuresis and the unmasking of central diabetes insipidus.

    Antineutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis is a life-threatening disease characterized by rapidly progressive glomerulonephritis (RPGN) and diffuse alveolar hemorrhage (DAH). Glucocorticoids and immunosuppressants are commonly used to treat this disease but may induce irreversible side effects, particularly in elderly patients. We herein report the case of a 76-year-old woman with RPGN. After methylprednisolone pulse therapy, DAH occurred, and she required ventilatory support. After plasma exchange, her serum creatinine level improved, and she was discharged with home oxygen therapy. Immunosuppressive agents other than glucocorticoids were not required. In conclusion, plasma exchange with glucocorticoid therapy may be effective in treating severe ANCA-associated vasculitis in elderly patients.

    A 42-year-old man developed nephrotic syndrome and rapidly progressive renal failure. Kidney biopsy demonstrated nodular glomerulosclerosis, negative Congo red staining, and no deposition of light or heavy chains. Laser micro-dissection and liquid chromatography with tandem mass spectrometry of nodular lesions revealed the presence of a kappa chain constant region and kappa III variable region, which signified light chain deposition disease. Dexamethasone and thalidomide were effective in decreasing the serum levels of free kappa light chain from 147.0 to 38.0 mg/L, eliminating proteinuria, and halting the worsening of the kidney dysfunction, with serum creatinine levels stable around 4.0 mg/dL for 3 years.

    Pulmonary tumor thrombotic microangiopathy (PTTM) is a high-mortality disease that is difficult to diagnose clinically. Our patient was an 80-year-old woman who came to us due to symptoms of increasing dyspnea. A clinical evaluation showed that she had hypoxemia and pulmonary arterial hypertension without any abnormalities in the major pulmonary arteries, bronchi, or alveoli. A lung perfusion scan showed multiple wedge-shaped perfusion defects. Further examination revealed adenocarcinoma in her right parotid gland with metastasis to the submandibular lymph nodes. We diagnosed her to have PTTM caused by a parotid tumor. The patient survived for 11 months with chemotherapy. An early antemortem diagnosis by minimally invasive examinations will help PTTM patients to survive longer.

    Human T-cell lymphotropic virus type 1 (HTLV-1) is a retrovirus involved in the pathogenesis of adult T-cell leukemia (ATL) and HTVL-1-associated bronchioloalveolar disorder (HABA). The clinical and pathological findings of HABA have been characterized as either a diffuse panbronchiolitis (DPB) pattern or idiopathic interstitial pneumonia (IIP) pattern. Treatments for HABA include corticosteroids for the IIP pattern and erythromycin for the DPB pattern. We herein report a case of HABA-associated unclassifiable interstitial pneumonia that improved with combined therapy with pirfenidone and erythromycin. This is the first report on the effectiveness of combined therapy with pirfenidone and erythromycin for HABA.

    Although pneumothorax has been reported to be a major pulmonary adverse event in patients treated with pazopanib, a multikinase inhibitor, drug-induced interstitial lung disease (DILD) has not been reported. A 74-year-old Japanese man who received pazopanib for the treatment of femoral leiomyosarcoma and lung metastasis presented with dyspnea and fatigue. He had mild interstitial pneumonia when pazopanib treatment was initiated. Chest computed tomography revealed progressive bilateral ground-glass opacity (GGO) and traction bronchiectasis. We diagnosed DILD due to pazopanib. The patient's pazopanib treatment was interrupted and a steroid was administered. The symptoms and GGO were improved with treatment. Physicians should be aware of DILD due to pazopanib in patients with pre-existing interstitial lung disease.

    Few cases of IgA nephropathy with angioimmunoblastic T-cell lymphoma (AITL) have been reported. We herein present the case of a 79-year-old Japanese man with AITL and IgA nephropathy. The patient presented with generalized edema, fatigue, and fever. Laboratory investigations revealed polyclonal gammopathy with a high level of IgA, microscopic hematuria, proteinuria, and some other immunological abnormalities. Computed tomography revealed generalized lymphadenopathy. A diagnosis of AITL and IgA nephropathy was made based on inguinal lymph node and renal biopsies. Following chemotherapy for AITL, the patient's edema, microscopic hematuria, and proteinuria were alleviated. These findings indicate that IgA nephropathy may occur in AITL patients.

    We herein report the case of a 72-year-old-man with pulmonary cryptococcoma along with cryptococcal meningitis who underwent surgery for pulmonary lesions while receiving chemotherapy. We noted two major clinical issues. First, the presence of pulmonary cryptococcoma had a detrimental influence on the cryptococcal meningitis. Second, resolution of the pulmonary cryptococcoma through antifungal therapy had a beneficial influence on the recovery from cryptococcal meningitis. As observed in the current case with pulmonary and meningeal cryptococcosis, surgery for pulmonary cryptococcoma with continuous antifungal treatment should be considered for cases where the symptoms respond poorly to antifungal therapy and radiographic abnormalities persist.

    The clinical features of mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) are not uniform. We herein report a male patient with unusual MELAS-like encephalopathy who had been experiencing isolated recurrent stroke-like episodes since he was 33 years old without any particular family history. Despite an extensive investigation, he had no other signs suggestive of MELAS. Although the muscle pathology showed a normal appearance, a mitochondrial genome sequence analysis of the biopsied muscle revealed a heteroplasmic m.10158T>C mutation in the mitochondrial complex I subunit gene, MT-ND3. To prevented further deterioration of the higher brain function, the early diagnosis and treatment of mitochondrial stroke-like episodes is important.

    Renal cell carcinoma (RCC) patients who develop a paraneoplastic syndrome may present with neuromuscular disorders. We herein report the case of a 50-year-old man who suffered from progressive gait disturbance and muscle weakness. The results of a nerve conduction study fulfilled the criteria of chronic inflammatory demyelinating polyneuropathy. An abdominal CT scan detected RCC, the pathological diagnosis of which was clear cell type. After tumor resection and a single course of intravenous immunoglobulin therapy, the patient's symptoms drastically improved over the course of one year. The patient's neurological symptoms preceded the detection of cancer. A proper diagnosis and the initiation of suitable therapies resulted in a favorable outcome.

    A patient with chronic alcoholism presented with myelopathy and low serum folate and cobalamin levels. A 42-year-old alcoholic man had gait disturbance for 4 months. A neurological examination revealed marked spasticity with increased deep tendon reflexes and extensor plantar responses of the lower limbs. His cobalamin level was decreased and his serum folate level was particularly low. His plasma ammonia level was not increased. Abstinence and folic acid and cobalamin supplementation stopped the progression of his neurological deficits. This case indicates that nutritional deficiency should be monitored closely in patients with chronic alcoholism who present with myelopathy.

    Reactivation of hepatitis B virus (HBV) is a serious complication of immunosuppressive therapy and cytotoxic chemotherapy. The optimal duration of HBV-DNA monitoring for at-risk patients depends on the clinical features of reactivation, especially the range of potency from therapies to reactivation. We present a case of very late reactivation after chemotherapy for lymphoma and review previous reports of late reactivation cases. We also underscore the significance of developing an indicator for anti-HBV immunity which can be used to determine the optimal monitoring period.
