The tracheal tumor of a 74-year-old female was detected on bronchoscopy and histologically diagnosed as mucosa-associated lymphoid tissue (MALT) lymphoma. We successfully treated the tumor with endoscopic neodyminum-yttruim-aluminium-garnet (Nd-YAG) laser photoresection followed by local ethanol injection. This is the first case in which tracheal MALT lymphoma was successfully treated with bronchoscopy. Bronchoscopic therapy seems to be one of the most valuable strategies for treatment of MALT lymphomas of the central airway.

Multicenter Study Comparative Study
Prediction of life expectancy in patients with primary pulmonary hypertension. A retrospective nationwide survey from 1980-1990.
Primary pulmonary hypertension (PPH) is a progressive disease of unknown etiology usually followed by death within 5 years after diagnosis. Although heart-lung or lung transplantation is now offered to patients with advanced PPH, adequate criteria assessing an accurate prediction of life expectancy in PPH has been difficult to establish. The aims of this study were to identify the characteristic features associated with a poor prognosis in patients with PPH, and to attempt to establish an individual prognostic index that predicts with great accuracy survival or death of PPH after one year, thereby helping to define criteria for patient selection for transplantation. ⋯ As the independent factors, PPA, PRA, SI, and PaCO2 were selected for the multiple logistic analysis. Using a 0.7 probability cut-point to separate Nonsurvivors from Survivors, 84.6% of Nonsurvivors and Survivors could be correctly predicted from this logistic regression equation. Predictive equations like the present preliminary one can be used in the future to better assess life expectancy in patients with PPH in whom transplantation will be considered.

Comparative Study
Relationship between glycosylated hemoglobin and the prevalence of proteinuria in Japanese men.
A total of 5,174 Japanese men were included in a cross-sectional study to examine the relationship between the glycated hemoglobin (HbA1C) level and the prevalence of proteinuria as determined using a reagent strip. The prevalence of proteinuria rose significantly at HbA1C levels above 5.9%, whereas no relationship was observed at HbA1C levels below 5.9%. ⋯ These findings suggest that maintaining a HbA1C level below 5.9%, non-smoking and a standard body weight may reduce the prevalence of proteinuria in Japanese men. Healthy life-style and standard body weight are especially important for subjects with a family history of diabetes.

A 48-year-old woman developed hepatic metastases from malignant pheochromocytoma resected 8 years previously. Angiography revealed multiple tumor stains in the liver. Transcatheter oily chemoembolization using styrenomaleic acid neocarzinostatin and iodized oil was performed. ⋯ Necrotizing cholecystitis developed on the 4th day post-transcatheter oily chemoembolization, hepatic infarction on the 12th day, and a biloma on the 19th day. Despite the administration of antibiotics and percutaneous transhepatic drainage, neither the volume of drainage nor the size of the biloma decreased. Biliary reconstruction was performed using a metallic stent, which decreased the size of the biloma.

Case Reports
Disturbance of consciousness associated with hypophosphatemia in a chronically alcoholic patient.
A 69-year-old man with chronic alcoholism was admitted to our hospital due to disturbance of consciousness and oliguria. Emergency laboratory examination revealed metabolic acidosis, hypoglycemia, hyponatremia, mild liver dysfunction, acute renal failure and rhabdomyolysis. ⋯ Since severe hypophosphatemia persisted, we administered adequate phosphates, and then his level of consciousness normalized. We discuss the relationships among alcohol abuse, hypophosphatemia and disturbance of consciousness, and recommend that hypophosphatemia be considered a potential cause of disturbance of consciousness in alcoholic patients.
