AbstractAbstract PDF
Wolfram-like disorder is one of the WFS1-related disorders that are caused by mutation of the WFS1 genes. WFS1-related disorders are classified as Wolfram syndrome, Wolfram like disorder and nonsyndromic low-frequency sensorineural hearing loss (DFNA6/14/38). Wolfram syndrome is known to DIDMOAD (diabetes insipidus, diabetes mellitus, optic atrophy and deafness), and it is an autosomal-recessive disorder that predisposes a patient to developing type 1 diabetes in association with progressive optic atrophy, and the disease shows various phenotypes. Wolfram like disorder is an autosomal-dominant disorder that predisposes a patient to develop type 2 diabetes in association with optic atrophy and hearing impairment. We experienced a case of Wolfram like disorder with diabetes, optic atrophy and sensorineural hearing loss in a 28-year-old woman who was admitted to our hospital. Our case demonstrated the E737K missense mutation on the WFS1 gene, which has been previously reported in the medical literature. The diagnosis of WFS1-related disorder was confirmed by the clinical features and molecular genetic testing of the WFS1 gene.

AbstractAbstract PDF
BACKGROUND
Thyroid nodules are a common disease in clinical practice. The prevalence of thyroid nodules has recently been increased by according to the development of thyroid ultrasonography. Thyroid nodules are more commonly found in women, but the potential for malignant nodules is much higher in men. So, we aimed to focus on the prevalence of thyroid nodules in the adult male population. METHODS: We studied men over the age of 30 who visited our health care center for routine health check-ups from January, 2005 to December, 2005. After excluding the patients with previous thyroid disorders, 1081 men were selected to undergo thyroid ultrasonography for detecting the presence of thyroid nodules. If nodules were found, then their size and numbers were recorded. These data were then correlated with the age of the patients. If needed, ultrasound-guided fine needle aspiration was performed. RESULTS: Among the 1,081 subjects, thyroid nodules were detected in 152 (14.1%) with its prevalence increasing with the increasing age of the patients (age 30 to 49: 12.3%, over 50: 17.2%, P = 0.026). Among these study subjects, nodules larger than 5 mm in size were detected in 99 patients and fine needle aspirations were performed on 53 of these patients. Six patients were diagnosed with papillary carcinoma. CONCLUSION: The prevalence of thyroid nodules in the male population was 14.1%, with an increasing prevalence in the over 50 age group.

AbstractAbstract PDF
Acute adrenal insufficiency may result from adrenal crisis, hemorrhagic destruction, or the rapid withdrawal of steroids from patient with chronic steroid medication, congenital adrenal hyperplasia or those on other drugs. Acute hemorrhagic destruction of both adrenal glands can occur due to infection, trauma, anticoagulant therapy, antiphospholipid syndrome or a coagulation disorder. However, there have been no reports on acute hemorrhagic adrenal insufficiency due to the Ebstein-Barr virus (EBV). Herein, a case of acute adrenal insufficiency, with bilateral adrenal hemorrhagic infarction, is reported in a patient with asymptomatic chronic adrenal insufficiency. A 42-year-old man presented with general weakness, weight loss and hyperpigmentation of several months duration. He suffered from a sore throat, general myalgia and a headache on admission. The laboratory findings were lymphocytosis, positive EBV IgM antibody, low cortisol level and a high level of adrenocorticotropic hormone (ACTH). Adrenocortical autoantibody and PCR for Mycobacterium tuberculosis showed negative findings. The serologic findings for CMV and HIV were negative. Fine needle aspiration of the adrenal gland revealed a hemorrhagic infarction and positive staining for the anti-EBV antibody. Acute adrenal insufficiency was then diagnosed with a bilateral adrenal hemorrhagic infarction due to the EBV infection in the patient, also with asymptomatic chronic adrenal insufficiency. This is the first case of acute adrenal insufficiency with bilateral hemorrhagic infarction, due to an EBV infection
