Age-related changes in clinical features of 182 patients diagnosed as having pulmonary tuberculosis from positive culture results of tubercle bacilli were extensively investigated. The percentage of cases detected using mass miniature radiophotography (MMR) was highest in the patients aged 30-39 years, and then decreased with increasing age. It was only 16-19% in those aged 60 years or older. Certain conditions, such as cardiovascular diseases, hypertension, diabetes mellitus, malignancy and other lung diseases, were common in the patients aged 60 years or older. Systemic symptoms, including weight loss and anorexia, and physical abnormalities, including fever and crackles, were common in these patients. Anemia tended to be predominant in the patients aged 60 years or older. The middle/lower lobes were involved more frequently in these patients, in whom the disease distribution was more than one lobe, or disseminated. Positive smear results and negative anergy were more frequently noted in the patients aged 60 years or older. The mortality from tuberculosis in these patients was 4% (7 cases). Although gastrointestinal disorder due to antitubercular drugs was more common in the patients aged 80 years or older, eosinophilia was less frequently observed. Today, improved conditions, better sanitation and the development of new chemotherapeutic agents have contributed to the decline of tuberculosis among the general population. But more efficient procedures that allow the early detection or diagnosis of pulmonary tuberculosis in the elderly should be achieved as soon as possible.

The ideal body weight (kg) of each individual can be calculated by the following formula: ideal body mass index x the height (m)2, since body mass index is expressed by the body weight in kilogram divided by the height squared in meters. We investigated an ideal body mass index with respect to morbidity in 4565 Japanese men and women aged 30-59 years. Ten medical problems served as indices of morbidity: lung disease, heart disease, upper gastrointestinal disease, hypertension, renal disease, liver disease, hyperlipidemia, hyperuricemia, diabetes mellitus and anemia. The value of body mass index associated with the lowest morbidity was 22.2 kg/m2 in men and 21.9 kg/m2 in women, according to the quadratic regression curves relating body mass index to morbidity. From these findings, we propose that the ideal body weight is 22 x height (m)2. Our recommendations apply to the age group studied, namely 30-59 years.

Two hundred twenty dietitians participated in a workshop conference on Health Implications of Dietary Fiber. They were given lectures to increase their knowledge base, and then in group sessions answered questions and wrote concensus opinions. The results are the content of this paper. The topics covered and responses are reported in four categories, diabetes and obesity, hyperlipidemia, hypertension and coronary heart disease, gut function and gastrointestinal disease, and cancer. Specific recommendation for implementing high fiber diets are made in each category. However, the dietitians expressed caution on accepting all of the conclusions expressed in the literature on the value of fiber and believed much education and instruction is needed in order to increase dietary fiber intake.

We studied the pupillary cardiovascular and gastrointestinal effects of two parasympathetic blocker mydriatics. Thirty-four neonates were randomly assigned into 3 groups: A: Atropine sulfate 0.3%, B: Tropicamide 0.5%, C: placebo. Mydriasis was obtained in groups A and B (p less than 0.001). No hypertension was observed and only an increase in heart rate with atropine was significant (p less than 0.001). Gastrointestinal side-effects studied in 25 children revealed a disturbance in groups A and B as compared to placebo (p less than 0.01). Tropicamide is therefore a more useful drug in low birth weight infants due to the absence of cardiovascular and hypertensive side-effects. Those infants with gastrointestinal disease should be treated with caution due to the side-effects which may be encountered.

The authors retrospectively investigated 62 diabetics who had received dialytic therapy at our department and our associated hospital over the past 10 years. We studied the complications and causes of death among the 62 subjects. Of the 62 patients (male 42, female 20), 27 (male 21, female 6), had died. The causes of death in the 27 cases included 7 from general weakness, 4 from gastrointestinal bleeding, 4 from cerebrovascular hemorrhage or thrombosis, 3 suicide, 3 congestive heart failure, 2 myocardial infarction, 2 hyperkalemia, 1 infection and 1 from hepatoma. With regard to diabetic retinopathy, 19 of the 62 patients suffered from bilateral blindness and 12 from unilateral blindness. In 8 patients, visual complications developed after hemodialysis, but 16 patients were already blind at the introduction of hemodialysis. There was no evidence that retinopathy was accelerated by dialysis and the authors suggest that the treatment of retinopathy is very important at the nondialyzed stage. With regard to other complications in dialyzed diabetics, unstable hypertension, diabetic gastroenteropathy, peripheral neuropathy, ischemic heart disease and gangrene were discovered in our population. Some rehabilitation was possible in all but 3 of the subjects (1 peripheral neuropathy, 2 leg amputation).

To identify the prescribing patterns in public group practice centers (GPCs), 84,453 prescription sheets written by primary care physicians in 168 GPCs during the period from December 7-12, 1992, were collected and analyzed. The average number of drugs per script was 4.3 and the ratio of drug to total medical expense was 44%. The 5 most common diagnoses were, in a descending order, upper respiratory tract infection, skeletomuscular and joint disease, hypertension, functional gastrointestinal disorder (including peptic ulcer) and diabetes mellitus. The top 5 most commonly dispensed drug categories were antacids and anti-ulcer drugs, anti-cough and anti-cold preparations, vitamins, simple analgesics and non-steroidal anti-inflammatory drugs, accounting for 48.8% of total prescriptions. In view of the frequency of relevant diagnoses, the overuse of antacids, vitamins, intravenous nutrient and electrolyte solutions, anti-cold preparations and antibiotics was apparent, as was that of drugs of questionable pharmacological value. These data indicate that polypharmacy is a widespread phenomenon and confirms our long-term concern over irrational drug use in GPCs in Taiwan. Both administrative and educational intervention should be implemented to improve prescribing quality at the primary health care level.

Essential hypertension and gastrointestinal disease are two of the most common diagnoses made in the doctor's office. Since they may occur simultaneously, the differential therapeutic aspects of the respective therapies are of importance for every general practitioner. However, complex interactions between hypertension and gastrointestinal diseases often make the choice of the most suitable drug difficult. The present article provides an overview of the most common therapeutic regimens, identifies possible interactions, and should help the doctor to select the optimal treatment for the individual patient.

Vincristine, referred to as a vinka alkaloid, has been used as a component of the various chemotherapeutic regimens. The major side effects of the usual dosage of vincristine are bone marrow suppression, gastrointestinal disorder, and neurotoxicity. A 53-year-old cervical cancer patient received 14 mg (4 mg/m2/day for 2 days) of vincristine instead of vinblastine because of the similarity between the two names. Then life threatening toxicities including paresthesias, bone marrow depression, severe oral mucositis, paralytic ileus, bladder atony, myalgia, muscle weakness, high fever, derangements of various organs (liver, heart), hypertension, and insomnia were encountered. But hypotension and syndrome of inappropriate secretion of antidiuretic hormone (SIADH) were not observed. Other than paresthesias in the extremities, the patient recovered completely from toxic impairments with intensive symptomatic and supportive care. In order to prevent the administration of the overdosed drug, it would be advisable for chemotherapy to be administered only by an experienced physician who is able to check the dose and concentration.

Glycerol is a naturally occurring 3-carbon alcohol in the human body. It is the structural backbone of triacylglycerol molecules, and can also be converted to a glycolytic substrate for subsequent metabolism. Serum glycerol concentrations approximate 0.05 mmol/L at rest, and can increase to 0.30 mmol/L during increased lipolysis associated with prolonged exercise or caloric restriction. When glycerol is ingested or infused at doses greater than 1.0 g/kg bodyweight, serum concentrations can increase to approximately 20 mmol/L, resulting in more than a 10 mOsmol/kg increase in serum osmolality. Glycerol infusion and ingestion have been used in research settings for almost 60 years, with widespread clinical use between 1961 and 1980 in the treatment of cerebral oedema resulting from acute ischaemic stroke, intraocular hypertension (glaucoma), intracranial hypertension, postural syncope and improved rehydration during acute gastrointestinal disease. Since 1987, glycerol ingestion with added fluid has been used to increase total body water (glycerol hyperhydration) by up to 700 ml, thereby providing benefits of improved thermoregulation and endurance during exercise or exposure to hot environments. Despite the small number of studies on glycerol hyperhydration and exercise, it appears to be an effective method of improving tolerance to exercise and other heat-related stressors.

Anticoagulation is a treatment with significant and life threatening complications requiring that the balance of risk and benefit be individually assessed in each patient. The risks are greater in the elderly and those with hypertension, falls and gastrointestinal disease. The use of anticoagulants is now established in patients with symptomatic non-rheumatic atrial fibrillation, especially older patients with hypertension, cardiac failure or a large left atrium or left ventricular dysfunction. There is, however, no place for the routine use of anticoagulants in acute stroke or as part of secondary prevention in patients in sinus rhythm. There may be a place, though as yet the evidence would not support this, for the limited use of anticoagulants in special situations such as cortical venous thrombosis or carotid dissection.
