Double cancer of the stomach, one AFP-producing tumor.

In recent years, many cases of alpha-fetoprotein-producing gastric cancer (AFPGC) characterized by increased serum levels of alpha-fetoprotein (AFP) and AFP positivity of the gastric cancer have been reported. Here we present a case of AFPGC coexistent with a different histological type of gastric cancer: The AFPGC was Borrmann type 1 advanced gastric cancer with multiple liver metastasis and appeared to produce both AFP and des-gamma-carboxy prothrombin (PIVKA-II). The second cancer was IIc type early gastric cancer and did not produce AFP. Despite receiving palliative chemotherapy, the patient died, due to hepatic failure, 45 days after admission.

[Risk factors related to the wall thickness of the common carotid artery in elderly patients].

We used ultrasonography to evaluate atherosclerotic lesions in the common carotid arteries of 147 inpatients (82 men, 65 women; mean age, 72.2 years). We sought to determine the relation between these lesions and various risk factors for atherosclerosis, as well as the utility of ultrasonography in quantitative evaluation of atherosclerotic disease. A 7.5 MHz transducer was used and atherosclerotic lesions were evaluated on the basis of the thickness of their intimal-medial complex, which we term wall thickness. The relations between these measurements and age, sex, blood pressure, smoking history, lipid metabolism, diabetes mellitus, and atherosclerotic disease were studied. Wall thickness of the common carotid arteries correlated with age (men: r = 0.45; women: r = 0.38). Brinkman Index (r = 0.25), systolic blood pressure (r = 0.44), diastolic pressure (r = 0.18), and high-density lipoprotein cholesterol (HDL-C, r = -0.23). Multiple regression analysis with these risk factors as explanatory variables showed that age, Brinkman Index, systolic blood pressure, HDL-C, and diabetes mellitus contributed significantly to increased wall thickness. Wall thickness was significantly greater in patients with atherosclerotic disease such as cerebral infarction and ischemic heart diseases. These findings indicate that appropriate treatment for multiple atherosclerotic risk factors may be necessarily in the elderly.

[Health problems of elderly patients in a rural area].

The purpose of this study was to identify diseases frequently found in elderly populations in rural areas as well as to discuss the role of geriatric physicians in medical care for elderly patients. The study was conducted using ICHPPC-2-Defined (Japan version) which had been compiled by WONCA for the classification of diseases. The acute health problems treated by the clinic consisted of 183 types (2070 items) in 1916 patients seen during 19 months compared to 66 types of chronic problems consisting of 505 items in 179 patients. The most frequent acute complaints and health problems were acute infections of the upper respiratory tract, followed by diseases of the stomach and duodenum, then osteoarthritis and allied conditions. The most common chronic health problems were uncomplicated hypertension, osteoarthritis and allied conditions, osteoporosis, lipid metabolism disorders, complicated hypertension, cataract, and various other illnesses extending over all specialties of medicine. Geriatric physicians are required to have broad and multidisciplinary knowledge and skill to provide comprehensive and continual medical care for elderly patients in rural areas.

[Estimated production of coal-tar dyes (including dye aluminum lakes) based on official inspections in 1991].

The total number of official inspection of coal-tar dyes and their lakes from April in 1991 to March 1992 was 835. The quantity which passed inspection amounted to 240 tons in Japan. The official production of color dyes each month in summarised in Table 1 and that by various manufacturers in Table 2. The food coal-tar dye produced in the largest quantity was Food Yellow No. 4, occupying 44.6% of the total during this period.

[Estimated production by the official inspection of coal-tar dyes (including dye aluminum lakes) in 1990 based on official inspection figures].

The number of official inspections of coal-tar dyes and their lakes from april in 1990 till march in 1991 was 836 in total. The quantity passed amounted to 238 ton in Japan. The production of color for each month was summarised in Table 1, and by each producing company in Table 2. The food coal-tar dye produced in the largest quantity was Food Yellow No. 4, occupying 46.2% in this period.

[A case of bronchial asthma complicated with mediastinal, subcutaneous, peritoneal and epidural emphysema].

A case of a 16-year-old female with bronchial asthma complicated with mediastinal, subcutaneous, peritoneal and epidural emphysema was reported. The patient was admitted to our hospital because of dyspnea. Chest and abdominal X-ray films revealed mediastinal emphysema with peribronchial air sheath, subcutaneous emphysema in the neck and chest, and peritoneal emphysema. CT-scan revealed severe mediastinal, subcutaneous and epidural emphysema. These findings disappeared about 10 days after recovery from the attack. Diagnostic methods and the pathogenesis of air leak were also discussed.
