Case Reports
Spontaneous resolution of an acute spontaneous spinal epidural hematoma without neurological deficits.
A 46-year-old woman presented with sudden severe pain in the interscapular region. Physical examination, including detailed neurological evaluation, did not disclose any abnormalities. ⋯ To our knowledge, this report documents the first case of a spontaneous spinal spidural hematoma without neurological deficits. Spinal epidural hematoma may be more common than previously thought because some cases have probably been misdiagnosed as transient back pain of unknown etiology.

Case Reports
Development of hypercalcemic crisis in a Graves' hyperthyroid patient associated with central diabetes insipidus.
A 26-year-old man with Graves' hyperthyroidism associated with central diabetes insipidus (DI), initially showed hypercalcemic crisis. Initially, very low serum levels of intact parathyroid hormone (PTH) and 1,25-dihydroxy vitamin D3 and a moderate rise of serum C-terminal PTH related protein (C-PTHrP) were observed which strongly suggested a humoral hypercalcemia of malignancy due to PTHrP. ⋯ Mild hyperprolactinemia, no responses of growth hormone (GH) to insulin-induced hypoglycemia despite a normal growth hormone releasing hormone (GRH) test and mild thickening of the pituitary stalk on magnetic resonance imaging were observed. Thus, an autoimmune nature of his central DI is considered; it is noteworthy that the serum C-PTHrP level may be elevated by renal failure in patients with hypercalcemia due to causes other than PTHrP.

A 62-year-old man with adult T cell leukemia (ATL) presented with complaints of anorexia and abdominal fullness. Evaluation revealed ascites and pleural effusion, but no lymph node swelling, hepatosplenomegaly, or skin involvement. The diagnosis of ATL was made by the detection of specific surface markers for T lymphocytes in pleural effusion and ascitic fluid, and by determination of human T cell leukemia virus type I (HTLV-I) proviral DNA integration in mononuclear cells of pleural effusion. This case was considered a rare type of ATL with infiltration of the pleura and peritoneum.

A 25-year-old man was admitted with complaints of fever and macrohematuria. Laboratory tests showed a substantial increase in serum creatine phosphokinase and creatinine in association with myoglobinuria and proteinuria. Blood culture grew Streptococcus salivarius and Streptococcus oralis. ⋯ Changes of the interstitium and tubules were not evident. The clinical course and laboratory results strongly suggested a possible link between Streptococcus salivarius/oralis infection, and rhabdomyolysis. Rhabdomyolysis is rarely seen as a complication of bacterial infection, and the present case emphasizes the importance of suspecting bacteremia due to Streptococcus salivarius/oralis in the presence of rhabdomyolysis.
