AbstractAbstract PDFPubReader   

The leading cause of morbidity and mortality in patients with acromegaly is cardiovascular complications. Myocardial exposure to excessive growth hormone can cause ventricular hypertrophy, hypertension, arrhythmia, and diastolic dysfunction. However, congestive heart failure as a result of systolic dysfunction is observed only rarely in patients with acromegaly. Most cases of acromegaly exhibit high levels of serum insulin-like growth factor-1 (IGF-1). Acromegaly with normal IGF-1 levels is rare and difficult to diagnose. Here, we report a rare case of an acromegalic patient whose first clinical manifestation was severe congestive heart failure, despite normal IGF-1 levels. We diagnosed acromegaly using a glucose-loading growth hormone suppression test. Cardiac function and myocardial hypertrophy improved 6 months after transsphenoidal resection of a pituitary adenoma.

AbstractAbstract PDF
The clinical characteristics of fulminant type 1 diabetes are abrupt onset of disease, very short (<1 week) duration of diabetic symptoms, ketoacidosis at diagnosis, negativity for islet-related autoantibodies, virtually no C-peptide secretion (fasting plasma C-peptide <0.3 ng/mL), a near normal hemoglobin A1c (HbA1c) level and an elevated serum pancreatic enzyme level. The pathogenesis has not yet been clarified, however the involvement of both genetic background and viral infections has been suggested. We reported a case of fulminant type 1 diabetes. A 37-year-old woman was admitted with stuporous consciousness to our hospital. Four days prior to the admission, she was hospitalized with the diagnosis of acute pancreatitis in another hospital, and at that time her glucose level was 79 mg/dL. Three days after the hospitalization, her state of consciousness became stuporous and she was transferred to our hospital. The laboratory results were as follows: pH 6.94, glucose 1,602 mg/dL, and HbA1c 5.5%. She was negative for islet-related autoantibodies and viral antibodies. HLA haplotypes were DRB1*04:05/*04:06, DQB1*03:02/*04:01 which might be a considerable risk allele for fulminant type 1 diabetes. She was diagnosed with fulminant type 1 diabetes, and has been treated with multiple component insulin regimens.

AbstractAbstract PDF
Papillary thyroid microcarcinoma (PTMC) is defined as being 1 cm or less in diameter. Although the prognosis of PTMC is known to be more favorable than that of papillary thyroid carcinoma greater than 1 cm in diameter, pathologic factors suggesting aggressiveness, such as multifocality and lymph node invasion, have been reported to be highly prevalent in PTMC. However, the rate of distant metastasis in patients with PTMC is very low. Many investigators have reported that initial distant metastasis was detected only in patients with PTMC greater than 0.4 cm in diameter, however these cases have involved only one organ, usually the lung. We report here on an extremely unusual case of solitary PTMC (0.3 cm in diameter) presenting multiple distant metastases at the time of diagnosis.
