: The aim of this study was to determine the relationships between free testosterone (FT) level and parameters including laboratory data and data from questionnaires and to determine symptoms leading to the detection of late onset hypogonadism (LOH). We retrospectively reviewed medical records of patients in whom serum FT was measured in our hospital. Aging Male Symptoms (AMS) score, self-rating depression scale (SDS) and frequency scale for the symptoms of gastroesophageal reflux disease (FSSG)...

: We herein report a case of central diabetes insipidus complicated with thyroid storm. A middle-aged woman who was receiving treatment for Graves' disease suddenly complained of polydipsia, polyuria and general fatigue. Laboratory tests showed hyperthyroidism, hypernatremia, hypoosmolar urine and a decreased plasma vasopressin level. The occurrence of central diabetes insipidus with hyperthyroidism was revealed on the basis of pituitary magnetic resonance imaging, a water deprivation test and a...

: A 72-year-old Japanese woman presented with a fever, diarrhea, intermittent spotting, and constant fluid discharge from the vagina. Imaging studies revealed an enterovaginal fistula. She underwent radical hysterectomy and radiotherapy 35 years previously. She also had a surgical history of nephrostomy, nephrectomy, ileoascending anastomosis, and colostomy. As bleeding from the enterovaginal fistula was uncontrollable, ileocecal resection was performed. However, a colovesical fistula with urina...

: A previously healthy 31-year-old man was referred to us with refractory septic shock accompanied by bilateral conjunctival congestion and erythema of his right lower limb. Nine days after admission, he had bilateral desquamation of the fingertips, and his presentation satisfied the criteria for Kawasaki disease. A serological examination was positive for Yersinia pseudotuberculosis, and he was diagnosed with Far East scarlet-like fever (FESLF). Interestingly, his 11-month-old baby boy had simi...

A 77-year-old female with renal dysfunction, hypercalcemia, and hypercalciuria was presented. Systemic investigations including renal biopsy showed that the patient had Fanconi syndrome secondary to renal sarcoidosis. Treatment with 25 mg per day of prednisolone was initiated and her condition improved. Complication of Fanconi syndrome in patients with sarcoidosis is extremely rare. Although the pathological mechanism is still unknown, corticosteroid therapy was effective for ameliorating protei...

: Insulinoma is a rare, usually benign, pancreatic neuroendocrine tumor. The clinical features of an insulinoma are fasting hypoglycemia with neuroglycopenic symptoms including confusion and unusual behavior, while hypertension is usually not associated with the disease. We herein report a patient with insulinoma who manifested paroxysmal hypertension and neuroglycopenic symptoms. The possible etiology of hypertension induced by an insulinoma is catecholamine release in response to hypoglycemia,...

: This study aimed to determine the prevalence of colorectal neoplasms and to investigate the rate of and time required for cecal intubation in patients with acromegaly. A database search performed at our institution identified 29 patients with acromegaly who underwent colonoscopy. Data regarding the endoscopic, biological, and pathological examinations performed were retrospectively reviewed from the clinical records. Subsequently, the rate of and time required for cecal intubation were investi...

A 61-year-old Japanese man with IgG4-related autoimmune pancreatitis was referred to our hospital because of perspiration during food intake. Abdominal computed tomography (CT) with contrast media revealed multiple mesenteric lymphadenopathies. An open surgical abdominal biopsy and subsequent histopathological analysis revealed abnormally large lymphoid cells that were negative for CD3, CD5, and c-myc and positive for CD20 and bcl-2, leading to a diagnosis of diffuse large B-cell lymphoma. Here,...

A 74-year-old man who had been administered trimethoprim-sulfamethoxazole for three weeks suffered from drug-induced hypersensitivity syndrome/drug rash with eosinophilia and systemic symptoms (DIHS/DRESS). In the early stage of the clinical course, he developed renal dysfunction. A renal biopsy showed granulomatous tubulointerstitial nephritis accompanying the proliferation of human herpes virus (HHV)-6 in tubular epithelial cells. With corticosteroid therapy, the systemic rash and renal functi...

KL-6 is a glycoprotein found predominantly on type II pneumocytes and alveolar macrophages, and often shows increased serum levels in patients with interstitial pneumonia. We report a case of mycobacterium avium complex (MAC) infection whose disease activity was correlated with KL-6 levels in serum. During treatment of rheumatoid arthritis (RA)-associated interstitial lung disease (ILD) with prednisolone, chest image findings improved in association with decreased KL-6 levels. Following tapering...
