    Objective Capsule endoscopy (CE) allows direct examination of the small bowel in a safe, noninvasive and well-tolerated manner. Nonetheless, experience indicates failure to reach the cecum in 20-30% of patients within the 8 hour battery life. Attempts to improve the completion rate (CR) as defined by reaching the cecum have been unsuccessful. This study was to investigate the relationship between patients' physical activity and CR.
    Methods Between January 2009 and January 2010, 76 patients (44 men, 32 women; median age 64.5 yr) underwent CE for the diagnosis of small intestinal disorders. Indications for CE were obscure gastrointestinal bleeding/anemia (62 cases), others (14 cases). Patients were divided into an outpatient group (n=23), mild bed rest group (n=35) and strict bed rest group (n=18).
    Results For all patients, the average gastric transit time was 65.5 minutes, small bowel transit time was 301.4 minutes and the CR was 86.8%. However, the CR was 100% (23/23) in the outpatient group, an 85.7% (30/35) in the mild bed rest group, and 72.2% (13/18) in the strict bed rest group. The CR increased with physical activity of patients by Cochran-Armitage Trend Test (p=0.009). In multivariate logistic regression analyses, low physical activity was a significant risk factor for failure to reach the cecum during CE examination; adjusted OR: 3.39, 95% CI: 1.01-11.42 (p=0.048).
    Conclusion Our observations suggested that increasing physical activity would increase the likelihood of a complete bowel examination by CE. Further, for CE, inconvenient bowel preparations like the use of polyethylene glycol may be avoided.

    Objective The aim of this hospital-based cohort study was to clarify the independent association between silent brain infarct (SBI) and arterial stiffness indicated by brachial-ankle pulse wave velocity (baPWV) including the cutoff value for SBI.
    Methods We studied 240 consecutive patients (mean age 69 years) with no history of stroke. We assessed the presence of SBI, white matter hyperintensities (WMHs), and risk factors. Arterial stiffness was evaluated using baPWV. We measured the intima-media thickness of the common carotid artery (CCAIMT) using carotid ultrasonography. We divided patients into two groups according to the presence or absence of SBI, and compared clinical characteristics between the two groups.
    Results In multivariable analysis, increased baPWV [by 1 m/s; odds ratio (OR) 1.13, 95% confidence interval (CI) 1.02-1.25] was independently associated with SBI. The baPWV cutoff value for SBI was 17.49 m/s. Patients with baPWV≥17.49 m/s had a higher possibility of the presence of SBI (OR 2.30, 95% CI 1.02-5.34) compared with patients with baPWV <17.49 m/s. Furthermore, the adjusted OR for the presence of SBI of the combination of baPWV≥17.49 m/s and CCAIMT≥1.1 mm (OR 2.73, 95% CI 1.24-6.11) was higher compared with that of baPWV≥17.49 m/s (OR 2.47, 95% CI 1.11-5.65).
    Conclusion Arterial stiffness is independently associated with SBI. Measurement of baPWV can indicate the presence of SBI, especially in patients with baPWV≥17.49 m/s.

    Objective Eicosapentaenoic acid (EPA) of the omega-3 polyunsaturated fatty acids (ω-3 PUFA) family plays important roles in the prevention of cardiovascular disease (CVD), while, arachidonic acid (AA) of the ω-6 PUFA family promotes inflammatory and prothrombotic influences. The complexity of coronary lesions represents the vulnerability of patients. The aim of this study was to investigate the association between the plasma EPA/AA ratio and the prevalence of complex coronary lesion morphology.
    Methods This study consisted of 206 consecutive patients with stable angina pectoris (sAP). Each coronary lesion was determined either as complex or simple based on angiographic findings. To examine the plasma fatty acid level, blood samples were obtained. Patients were divided into three groups according to the obtained plasma EPA/AA ratio: the highest tertile, n=67, the 2nd tertile, n=70, or the lowest tertile, n=69.
    Results A higher incidence of complex coronary lesion was obtained from patients with a lower plasma EPA/AA ratio [43 (62%) vs. 31 (44%) vs. 25 (37%), p=0.011]. High-sensitivity CRP levels and a low plasma EPA/AA ratio could independently predict the prevalence of complex coronary lesions on multivariate logistic regression analysis [odds ratio 1.83 (95%CI 1.03-3.25), p=0.038 and odds ratio 2.10 (95%CI 1.11-3.94), p=0.02)].
    Conclusion In patients with sAP, a low plasma EPA/AA ratio was significantly associated with a high prevalence of complex coronary lesions.

    Objective To analyze the incidence rates and risk factors for bacteremia in patients undergoing hemodialysis (HD) and peritoneal dialysis (PD).
    Methods The records of 898 consecutive patients undergoing dialysis from January 2003 to December 2008 were reviewed retrospectively. Episodes of bacteremia were recorded. China Medical University (Taichung, Taiwan).
    Results The overall incidence rate of bacteremia was 7.63 per 100 patient-years in HD patients and 3.56 per 100 patient-years in PD patients and it was higher in HD patients each year from 2003 to 2008. S. aureus (27.53%) was the most common pathogen in HD patients, whereas Coagulase-negative Staphylococcus (21.3%) was the most common pathogen in PD patients. Vascular access infection was the most common etiology in HD patients, whereas peritonitis was the most common etiology in PD patients. Older age, shorter dialysis vintage, use of HD rather than PD, current smoker, use of a venous dialysis catheter, presence of diabetes mellitus, higher comorbidity score, and lower serum albumin were significant risk factors for bacteremia. Diabetes mellitus and lower serum albumin were significant risk factors for bacteremia-associated mortality.
    Conclusion Placement of a permanent access (fistula, graft, or PD catheter) prior to initiation of dialysis, smoking cessation, and better nutritional status (i.e. higher serum albumin) were associated with a reduced risk of bacteremia in dialysis patients. Higher serum albumin was also associated with a reduced bacteremia-associated mortality.

    Symptomatic Meckel's diverticulum is an uncommon diagnosis in adults, and bleeding Meckel's diverticulum after childhood is even more infrequent. We present herein the case of a 22-year-old man with gastrointestinal hemorrhage secondary to Meckel's diverticulum containing ectopic gastric mucosa. As the source of bleeding could not be identified by upper and lower gastrointestinal endoscopy and visceral selective angiography, the new methods of capsule endoscopy and double-balloon endoscopy were used. Capsule endoscopy showed oozing hemorrhage in the ileum, and double-balloon endoscopy demonstrated a large diverticulum in the distal part of the ileum. Tc-99m pertechnetate Meckel's scan revealed an abnormal focus of uptake in the right lower abdomen. The diverticulum was resected laparoscopically. The postoperative course was uneventful, and the patient remains in complete remission as of this writing. Detecting Meckel's diverticulum endoscopically is difficult prior to surgery, but a combination of capsule endoscopy and double-balloon endoscopy facilitates examination of the entire small intestine, making precise diagnosis of Meckel's diverticulum possible.

    We report a case of primary malignant mesothelioma of the appendix. A 35-year-old man without any history of asbestos exposure was admitted to our hospital for further examination following the discovery of multiple liver tumors, an ileocecal tumor, and abdominal lymph node swelling. An ultrasound-guided liver tumor biopsy revealed malignant mesothelioma. Despite receiving systemic chemotherapy, he died 3 months after the initial diagnosis. At autopsy, a diagnosis of multiple organ metastases from a malignant biphasic mesothelioma of the appendix was made. To our knowledge, this is only the second reported case of primary malignant mesothelioma of the appendix.

    A 52-year-old Japanese woman was diagnosed with primary follicular lymphoma of the duodenum that was curatively resected by pancreatoduodenectomy. She remained in complete remission until 11 years after the surgery, when multiple enlarged intra-abdominal lymph nodes were demonstrated by computed tomography scans and positron emission tomography scans. Two years later, jejunal lesions were detected by endoscopy, and biopsy samples confirmed a recurrence of follicular lymphoma. This case indicates that primary gastrointestinal follicular lymphoma has a potential of relapse after an extended period of time, and thus patients must be followed up for over 10 years after complete remission.

    Cardiac allograft vasculopathy is the leading cause of death after the first year of heart transplantation. The optimal treatment for unprotected left main coronary artery disease in orthotopic heart transplantation (OHT) patients is unknown. Two OHT patients with left main disease following heart transplantation underwent percutaneous coronary intervention (PCI). Technical success was achieved in the patients with drug-eluting stents inserted to cover the lesions in the left main coronary artery. After 16 months follow-up, one patient died of multiorgan failure, the other was alive and free from myocardial infarction or target vessel revascularization. We conclude that the unprotected PCI for the left main coronary artery stenosis in transplanted heart is feasible.

    A 44-year-old man presented with exertional dyspnea. Transthoracic echocardiography (TTE) revealed a large tumor protruding into the right atrium and extending into the left ventricle. Cardiac magnetic resonance imaging and contrast enhanced computed tomography also confirmed the intracardiac tumor detected by TTE. An endomyocardial biopsy was performed under the intracardiac echocardiography (ICE) guidance, and he was diagnosed to have diffuse large B-cell lymphoma following the histological analysis. ICE-guided cardiac tumor biopsy is expected to be a useful diagnostic strategy that can minimize the risk of procedural complications.

    An 87-year-old man with heart failure was admitted to our hospital. A transthoracic echocardiography showed diffuse mild left ventricular (LV) hypokinesis and LV noncompaction at the apex. A three-dimensional transthoracic echocardiography confirmed a trabecular meshwork. After treatment for heart failure, LV end-systolic dimension decreased and trabeculae seemed to converge and became obscure in end-systole. This is a rare case suggesting mechanism of obscured LV noncompaction after treatment for heart failure.

    A 47-year-old man with Cushingoid appearance was admitted to our hospital showing excessive secretion of cortisol at intervals of a few days. Cyclic Cushing's disease was confirmed. Two years earlier, results of hormonal assessment had been within normal limits and macroadenoma had been incidentally detected in the pituitary. Dexamethasone suppression testing revealed various responses and a small lung tumor was detected, therefore his condition was misinterpreted as ectopic ACTH-producing tumor or pituitary cyclical Cushing's disease, leading to lung resection that confirmed cryptococcal pneumonia. The pituitary tumor was finally identified as the cause of cyclic Cushing's syndrome and fully removed, allowing remission.

    Macro-creatine kinase (CK) is a cause of falsely elevated CK. Macro-CK type 1 is immunoglobulin-associated CK; type 2 is polymeric mitochondrial-CK. An elderly asymptomatic lady had an elevated CK level after receiving statin therapy. Her CK gel electrophoresis analysis demonstrated coexisting macro-CK type 1 and type 2 patterns. Further analysis by immunofixation and mixing this patient's serum with CK control material revealed an IgG-associated macro-CK that mimicked the electrophoretic pattern of macro-CK type 2. This highly unusual discovery suggests the possibility of the misinterpretation of macro-CK type 1 as macro-CK type 2. Falsely elevated CK is still common despite modern laboratory instrumentation and should be investigated.

    A 72-year-old woman with slowly progressive type 1 diabetes (SPIDDM) was admitted to our hospital because of increasing abdominal pain and diarrhea. The patient was diagnosed with nonocclusive mesenteric ischemia (NOMI), and a subtotal colonectomy was performed successfully. The resected sample revealed transmural gangrenous necrosis of the colon and rectum. This case is interesting because the severe NOMI occurred in a SPIDDM patient without common predisposing events such as hypoperfusion. Prolonged generation of reactive oxygen species in SPIDDM, together with the decline in adaptive response to oxidative stress with aging, might be an exacerbating factor for ischemic injury in the elderly.

    A 50-year-old man was admitted to our hospital because of general malaise. Laboratory tests revealed severe hyponatremia (104 mEq/L), which was attributed to central adrenal insufficiency. To treat presumed central diabetes insipidus (CDI), we administered a small dose of hydrocortisone and gradually increased it to maintenance doses to prevent osmotic demyelination syndrome (ODS). Serum sodium levels did not increase more than 10 mEq/L/day and ODS did not occur. Thereafter, the patient was proven to have CDI. Incremental increases in glucocorticoid dose may reduce the risk of ODS for patients with hyponatremia due to central adrenal insufficiency, especially that complicated by CDI.

    Polyarteritis nodosa is a systemic vasculitis of medium and small-sized arteries associated with aneurysm formation. Aneurysms may be complicated by thrombosis, rupture and hemorrhage. Kidney involvement in polyarteritis nodosa can rarely be complicated by Wunderlich syndrome which is characterized by acute onset of spontaneous, nontraumatic subcapsular and perirenal hematomas. A 22-year-old woman with mental retardation due to childhood cytomegalovirus infection presented with flank pain, weight loss and fever, and was found to have bilateral subcapsular and perinephric hematomas. Spontaneous bilateral renal hemorrhage as the initial manifestation of polyarteritis nodosa is rare, and it can be associated with delays in diagnosis and treatment.

    Metabolic acidosis is a frequently encountered acid-base disturbance in hospitalized patients that occasionally develops in the course of treatment with medications used in everyday clinical practice, including propylene glycol-containing drugs (lorazepam, diazepam, etomidate, pentobarbital). Disruption of enterohepatic circulation with activated charcoal is a common practice for several intoxications, including mushroom poisoning. Herein, we present a patient who was hospitalized due to mushroom intoxication and developed severe metabolic acidosis as a treatment side effect rather than from the mushroom poisoning. Τo the best of our knowledge, this is the first report on propylene glycol-containing activated charcoal-induced metabolic acidosis.

    Lenalidomide is a second-generation immunomodulatory drug that has been approved to treat relapsed or refractory multiple myeloma. Here, we describe a patient who was treated with a low dose of lenalidomide (5 mg/day on days 1-21 of a 28-day cycle) because the standard dose of bortezomib was too toxic and adverse events persisted. However, he developed fever, dyspnea, hypoxia and pulmonary infiltrates. The results of an extensive workup for other causes including infections were negative and the final diagnosis was lenalidomide-induced interstitial pneumonitis. This is the first case report of lenalidomide-induced pneumonitis in a Japanese patient.

A 45-year-old Japanese man was referred to our department due to recurrent lower respiratory tract infections that had started and ameliorated nine months after thymectomy for pure red cell aplasia and myasthenia gravis. Diffuse centrilobular opacities on chest computed tomography and positivity for HLA-B54 were consistent with DPB. Additionally, hypogammaglobulinemia and a marked decrease of B-lymphocytes were observed, and therefore Good syndrome was considered. Combination therapy with azithromycin and clarithromycin alleviated the patient's respiratory symptoms and reduced the exacerbation of chronic bronchitis.

    We herein report two cases of primary ciliary dyskinesia (PCD) with different responses to macrolides. Case 1: a 17-year-old Japanese man with Pseudomonas aeruginosa infection and combined defect of both inner and outer dynein arms in the cilia was unsuccessfully treated with long-term macrolides (clarithromycin, erythromycin, and azithromycin). Case 2: a 70-year-old Japanese man with deficiency of only the inner dynein arm was successfully treated with clarithromycin. Though the reasons for the different responses to macrolides are unclear, differences of ultrastructural abnormalities of the cilia might be one of the predictive factors in PCD just as in Pseudomonas aeruginosa infection.

    A 58-year-old immunocompetent man gradually developed loss of appetite, cognitive decline, gait disturbances, and personality changes over 4 months. Brain magnetic resonance imaging (MRI) revealed bilateral diffuse leukoencephalopathy without mass formation on admission. His condition progressively deteriorated, and we treated him with intravenous high-dose steroids. His symptoms improved rapidly, but exacerbated when therapy was withdrawn. A brain biopsy was performed, and the diagnosis of primary central nervous system lymphoma (PCNSL) was confirmed. He was successfully treated with high-dose methotrexate therapy. Although it is difficult to diagnose PCNSL without mass formation in the early stages, steroid responsiveness is important and brain biopsy is essential for the correct diagnosis of PCNSL.

    We report a 76-year-old man with paradoxical cerebral air embolism. He developed consciousness disturbance and left hemiparesis after a postural change in rehabilitation. CT showed multiple air densities within the right hemisphere. An echocardiography showed a large right-to-left (RL) shunt. We considered the reason to be that a small amount of air entered, and the Valsalva-like maneuver with the postural change moved air into arterial circulation through the RL shunt and embolized a brain artery. The present case showed that even a small amount of air in the venous circulation may become a potential risk for cerebral air embolism, especially in the presence of a large RL shunt.

    We encountered a patient with brain abscess presumably caused by dental infection. The patient displayed patent foramen ovale (PFO) and a giant Eustachian valve, through which spontaneous right-to-left shunt was revealed by transesophageal echocardiography. Reviewing the literature, we find additional cases where brain abscess originated from an increased amount of flora commonly found in the oral cavity that bypassed the pulmonary vascular bed and the lymphatic system through PFO. Additionally, a Eustachian valve should be considered an adjunctive risk factor for initiating a spontaneous right-to-left shunt and predisposing cryptogenic brain abscess in patients with PFO.

    Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) syndrome is a clinically and radiologically distinct pontine-predominant perivascular neuroinflammation showing T lymphocyte infiltration. It is assumed to have an autoimmune or other inflammatory mediated pathogenesis. We report the first known case of CLIPPERS in East Asia, characterized by multiple punctate enhancement of the brainstem extending to the bilateral posterior limb of the internal capsule and caudal to the spinal cord conus. The patient had elevated IgE levels and a history of allergies, suggesting that lesions may arise from neuroinflammation in response to T lymphocyte infiltration into perivascular spaces.

Brain magnetic resonance imaging showed one lesion in the left cerebellar hemisphere which showed postcontrast enhancement and one in the midbrain without postcontrast enhancement. No cardiac pathology was found and symptoms gradually improved after a 5-day course of corticosteroid therapy. It is important to bear in mind the possibility of these rare cardiac symptoms in MS patients, because of their timely recognition and appropriate treatment.

    A 17-year-old woman was previously diagnosed with autoimmune hepatitis (AIH) by liver biopsy. Adult-onset Still's disease (AOSD) was subsequently diagnosed on the basis of high fever, arthralgia, erythema, leukocytosis (>80% granulocytes), cervical lymph node swelling, splenomegaly, and hyperferritinemia. Her symptoms and liver dysfunction improved with prednisolone of 60 mg daily and subsequently methotrexate was added. However her symptoms and liver dysfunction relapsed when prednisolone was tapered to 20 mg/day. Therefore infliximab was introduced additionally and her symptoms and liver dysfunction subsided. To our knowledge, this is the first reported case of AOSD with AIH diagnosed by liver biopsy.

    A 60-year-old man was admitted to our hospital after being found at his home in a comatose state. Cerebrospinal fluid and blood cultures were positive for Streptococcus pneumoniae. Brain magnetic resonance imaging (MRI) revealed sinusitis in the sphenoid sinus. Computed tomography demonstrated the presence of multiple air pockets in the basilar cistern, and we diagnosed pneumococcal meningitis complicated with pneumocephalus. Multiple cerebral infarctions were found on brain MRI after admission. In this case, pneumocephalus was secondary to pneumococcal meningitis due to sinusitis on admission, and multiple cerebral infarctions after admission. We demonstrated that early diagnosis is required for the successful treatment of pneumococcal meningitis.

    An 86-year-old woman who underwent placement of a prosthetic aortic valve for regurgitation 5 years previously was admitted because of spiking fever. The blood culture results were positive for gram-negative rods, which were identified as Achromobacter xylosoxidans. Approximately 4 months after being sent to the hospital, transthoracic echocardiography revealed vegetation at the prosthetic aortic valve. Ultimately, a diagnosis of A. xylosoxidans endocarditis of the prosthetic aortic valve was made. We report an extremely rare case of bacteremia associated by prosthetic valve endocarditis with A. xylosoxidans. In addition, we review 10 previously reported cases of endocarditis caused by A. xylosoxidans.
