A 48-year-old man was admitted to our hospital with cough, fever and dysphagia. He had a past history of bronchial asthma and surgery for nasal polyp. ⋯ Gastrointestinal tract biopsy specimens showed submucosal infiltration of eosinophils. These findings led to a definite diagnosis of eosinophilic pneumonia associated with eosinophilic gastroenteritis, a disease which has been rarely reported.

Case Reports
Syndrome of inappropriate secretion of antidiuretic hormone associated with idiopathic normal pressure hydrocephalus.
A 79-year-old woman suffering from urinary incontinence and unsteady gait was diagnosed as having idiopathic normal pressure hydrocephalus (NPH) with hyponatremia due to the syndrome of inappropriate secretion of antidiuretic hormone (SIADH). The concentration of antidiuretic hormone was high while the plasma osmolality was low in the presence of concentrated urine during the episodes of hyponatremia. ⋯ After ventriculoperitoneal shunt surgery, the symptoms of NPH and hyponatremia improved. It may be possibly explained that mechanical pressure on the hypothalamus from the third ventricle is responsible for hyponatremia.

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.
