Objective Examination of sudomotor function is now recommended to assess peripheral autonomic dysfunction. The aim of this study was to evaluate the clinical usefulness of Neuropad, a simple visual indicator test, for assessment of diabetic polyneuropathy (DPN). Methods This study examined 87 diabetic patients with a mean age of 61.1±8.8 years, a mean diabetes duration of 13.0±7.5 years and a mean HbA1c of 8.8±1.7%. Diagnosis of DPN was based on clinical examinations using modified Toronto Clinical Neuropathy Score (mTCNS). The patients also underwent 4-g monofilament test and heart rate variability by coefficient of variation of R-R intervals (CVR-R) was determined with the patients at rest. The Neuropad test was applied on the plantar aspect of the great toe and removed after 10 minutes to evaluate the color change as normal (blue to completely pink), patchy (patches of blue and pink) and abnormal (remained blue). Results Twenty-eight patients showed a normal, 45 patchy and 14 abnormal response to the Neuropad test. Patients with an abnormal response had significantly longer diabetes duration than those with a normal or a patchy response, but HbA1c levels were similar among the three groups. The CR-R at rest was significantly lower in patients with an abnormal response than those of normal and patchy response, respectively. Abnormal responders showed significantly higher mTCNS and lower monofilament results as well as higher prevalence of orthostatic hypotension, retinopathy or nephropathy than normal responders. Conclusion The Neuropad test is a useful screening test for detecting DPN. © 2012 The Japanese Society of Internal Medicine.

A 22-year-old man with chronic active Epstein-Barr virus infection underwent allogeneic bone marrow transplantation (allo-BMT) from an HLA two allele-mismatched unrelated donor. Ten months after allo-BMT, he developed protein-losing enteropathy following a respiratory syncytial virus infection. A diagnosis of a recurrent type of acute graft-versus-host disease (GVHD) was made based on the histopathological findings, such as the infiltration of T lymphocytes into the superficial epithelium and crypts, and apoptotic bodies in crypts. Although methylprednisolone (mPSL: 10 mg/kg) administration for two consecutive days improved gastrointestinal symptoms, acute pancreatitis and severe depression developed in association with corticosteroid treatment. Reduction of mPSL and administration of infliximab (5 mg/kg/dose, 3 times) resulted in rapid improvement of depression and pancreatitis without aggravating intestinal GVHD. Recent studies have demonstrated that tumor-necrosis-factor (TNF)-α is associated with not only GVHD but also depression and acute pancreatitis. In the present case, anti-TNF-α treatment enabled us to reduce corticosteroid dose without aggravating GVHD, which suggests that this approach might be effective for the treatment of depression and acute pancreatitis.

Hypertrophic cardiomyopathy (HCM) patients often develop left--ventricular subendocardial ischaemia, a cause of chest symptoms, despite normal epicardial coronary arteries. The aim of this study was to examine whether ultrasonic tissue characterization or late gadolinium enhancement on cardiac magnetic resonance imaging can detect subendocardial ischaemia in patients with HCM. Subendocardial ischaemia was quantified on exercise Tc-99m tetrofosmin myocardial scintigraphy in 29 non-obstructive HCM patients with asymmetric septal hypertrophy. Ultrasonic tissue characterization using cyclic variation of integrated backscatter (CV-IB) and late gadolinium enhancement on cardiac magnetic resonance imaging were analysed separately in the right halves and the left halves of the ventricular septum in relation to subendocardial ischaemia. Subendocardial ischaemia was identified in 17 (59%) patients. The ratio of CV-IB in the right-to-left halves of the ventricular septum was significantly higher in patients with subendocardial ischaemia (1.19 ± 0.10) than those without (0.84 ± 0.10, P = 0.04). The optimal cutoff for the detection of subendocardial ischaemia was the ratio of CV-IB >1.0, with a sensitivity of 80%, specificity of 71%, and accuracy of 76%. On the other hand, late gadolinium enhancement was not associated with subendocardial ischaemia in our cohort. Ultrasonic tissue characterization using CV-IB separately in the right and left halves of the ventricular septum, but not late gadolinium enhancement on magnetic resonance imaging, provided useful information in detecting subendocardial ischaemia in patients with HCM. Ultrasonic tissue characterization may be useful in selecting patients who will benefit from medications to relieve chest symptoms.

An extremely rare case of mixed adenoneuroendocrine carcinoma (MANEC) of the gallbladder is reported, in which the tumor showed diverse differentiation toward neuroendocrine tumor (grade 2), tubular adenocarcinoma, squamous cell carcinoma, and, in addition, osteosarcoma. The patient was an 80-year-old man, who underwent cholecystectomy because of a large polypoid tumor filling the gallbladder lumen. The tumor consisted of an intimate admixture of neuroendocrine tumor (grade 2) and tubular adenocarcinoma, and, in many areas, cell nests of neuroendocrine tumor appeared to bud off from tubular structures of the adenocarcinoma, in a manner resembling the 'ductulo-insular complex' seen in nesidioblastosis of the pancreas. Small areas of squamous cell carcinoma were also found. The stroma consisted of a dense proliferation of atypical spindle cells showing focal osteosarcomatous differentiation, and an apparent transition from an epithelial tissue component to atypical spindle cells was observed. Immunohistochemically, neuroendocrine cells were positive for synaptophysin, chromogranin A, and serotonin, and the sarcomatoid stroma was partly immunoreactive for cytokeratin. The present case is the first example of MANEC of the gallbladder with simultaneous squamous cell carcinomatous and osteosarcomatous differentiation. 'Neometaplasia' of carcinoma cells in diverse directions was considered the most plausible explanation for the formation of this multifaceted neoplasm. © 2013 Japanese Society of Pathology and Wiley Publishing Asia Pty Ltd.

A 73-year-old woman was admitted to our hospital because of persistent fever, headache and fatigue for several weeks. On admission, she was diagnosed as having meningitis due to Mycobacterium intracellulare (M. intracellulare) detected in her cerebrospinal fluid (CSF) by polymerase chain reaction. Even though antituberculous therapy improved her CSF findings, her condition was not restored. Brain MRI showed multifocal and asymmetrical increases in T2 signals involving white matter and cortical gray-white junction of cerebral hemispheres, cerebellum and brainstem. Based on the progression of clinical symptoms and radiological features, we diagnosed her illness as acute disseminated encephalomyelitis (ADEM) associated with meningitis due to M. intracellulare. Steroid therapy dramatically improved her condition. This is the first report of ADEM following meningitis due to M. intracellulare in a non-immunocompromized host. © 2010 The Japanese Society of Internal Medicine.
