Intrahepatic cholangiocarcinoma with increased serum CYFRA 21-1 level.

CYFRA 21-1 is a fragment of cytokeratin 19 (CK 19). Four patients with large intrahepatic (or peripheral) cholangiocarcinoma (CC) and high serum levels of CYFRA 21-1 (normal, < or = 2 ng/ml) are reported. CYFRA 21-1 levels exceeded 9 ng/ml in all 4 patients.

Phenotypical heterogeneity of CD4+CD8+ double-positive chronic T lymphoid leukemia.

Chronic T lymphoid leukemias are defined as leukemias of post-thymic T cells. The CD4+CD8+ double-positive (DP) phenotype is seen in a few cases. Since DP generally occurs in thymic T cells, whether the DP T leukemia cells represent thymic or peripheral T cells has been a matter of controversy.

Anerythremic form of acute erythremic myelosis (Di Guglielmo's syndrome) causing hepatosplenomegaly due to the infiltration of hemoglobin-bearing blast cells: an autopsy case.

An autopsy case of a 42 year old man with the anerythremic form of acute erythremic myelosis (Di Guglielmo's syndrome) is reported. The patient was admitted because of a 1 month history of fatigue and fever. Physical examination showed hepatosplenomegaly.

IGF-II producing hepatic fibrosarcoma associated with hypoglycemia.

A 67-year-old male was admitted with the complaint of weakness at hunger early in the morning, when blood glucose was less than 40 mg/dl. The abdominal ultrasonogram and computerized tomogram demonstrated a huge tumor in the right liver lobe. Hypoglycemia disappeared after transcatheter arterial embolization.

A case of adult T-cell leukemia/lymphoma, histologically presenting CD30-positive large cell lymphoma.

A 48-year-old Japanese woman with adult T-cell leukemia/lymphoma (ATLL), histologically presenting CD30-positive large cell lymphoma is reported. The patient, who was from an ATLL endemic area in Japan, had cutaneous nodules in the head, trunk, and extremities, and cervical lymph node swelling; these had been found three months before her admission to our hospital. A biopsy specimen of a skin lesion showed diffuse large cell lymphoma; the lymphoma cells were positively stained with CD30 (Ki-1/Ber H-2), CD4 (helper-T), and CD25 (interleukin-2 receptor) antibodies.

Protein-losing enteropathy and pancreatic involvement in a case of connective tissue disease.

A patient with connective tissue disease presenting with both protein-losing enteropathy and pancreatic involvement is reported. A 52-year-old female was admitted because of mild epigastralgia, anasarca and ascites. Serum albumin, transferrin and zinc, showed low levels.

Prevalence of vascular complications in untreated diabetics with obesity during an 18 year period.

Prevalence of vascular complications in newly diagnosed untreated diabetic patients with obesity was studied over a period of 18 years. A total of 742 patients including 241 subjects with obesity (BMI greater than 25) were analyzed. Obese patients showed higher serum cholesterol and triglyceride and lower HDL-cholesterol levels than non-obese patients.

Glucose tolerance, blood lipid, insulin and glucagon concentration after single or continuous administration of aspartame in diabetics.

A nutritive sweetener, aspartame (L-aspartyl-L-phenylalanine methylester) was administered orally to normal controls and diabetic patients in order to evaluate effects on blood glucose, lipids and pancreatic hormone secretion. An oral glucose tolerance test was also performed in the same subjects as a control study of aspartame administration. In 7 normal controls and 22 untreated diabetics, a single dose of 500 mg aspartame, equivalent to 100 g glucose in sweetness, induced no increase in blood glucose concentration.

[Clinical evaluation of effectiveness of cefmetazole in bone and joint infections in the orthopedic field].

1. Cefmetazole (CMZ) was administered to a total number of 12 patients, 10 having acute or chronic osteomyelitis and 2 pyarthrosis in the orthopedic field. The efficacy rate was 91.
