The favourable clinical results of cardiac transplantation merit wider application of this therapeutic measure in the management of non-obstructive primary cardiomyopathies and diffuse myocardial fibrosis secondary to coronary artery disease and in its terminal phase, in the absence of any absolute contraindication (pulmonary resistance too high, diabetes, gastrointestinal disorder, infection, patient too old.). Close cooperation between departments of cardiology and surgical transplantation centres, with systematic study of the patients pre-operatively and the setting up of a waiting list of recipients, will make possible in the future the improvement of the already encouraging results of cardiac transplantation.

Glucose absorption rates in 14 Arabs in Saudi Arabia were determined by a jejunal perfusion technique and compared with those in 18 Africans in Zambia. None of the subjects had clinical evidence of systemic infection, gastrointestinal disease, malnutrition, or diabetes mellitus. The mean absorption rate was significantly higher in the Arabs. This was associated with a higher incidence of subclinical chronic systemic infection in the Africans. Other factors possibly responsible for the difference, including genetic difference, have, however, not been excluded.

Two studies examine the prevalence of tardive dyskinesia (TD) in neuroleptic-treated diabetic patients. Study 1 compared 38 diabetic patients with 38 nondiabetic patients treated for psychotic disorders with low to moderate doses of neuroleptics (mean chlorpromazine equivalents = 300 mg/day) for an average of 18 years. Study 2 compared 24 diabetic and 27 nondiabetic patients treated for an average of 2.6 years with a mean 31 mg/day of metoclopramide for gastrointestinal disease. Patients were examined for TD using standardized scales by raters blind to all treatment and illness variables. In both studies, there were no differences between the diabetic and nondiabetic groups in age, sex, type of psychiatric illness, and dose and duration of neuroleptic treatment or severity of parkinsonism. In both studies, the diabetic patients had significantly greater prevalence and severity of TD. No measures of diabetes severity were associated with TD in either study. Possible pathophysiologic mechanisms for the increased prevalence of TD in neuroleptic-treated patients with diabetes will be discussed.

The extent to which hemodialysis patients rely on nephrologists for primary medical care is unknown. The authors surveyed 74 in-center hemodialysis patients to obtain demographic data and information about primary medical care and subspecialty referrals and follow-up. Health care maintenance was also assessed. All patients were dialyzed in a free-standing university affiliated dialysis unit. The mean age of the patients was 55 +/- 17 years; most were women (43/74) and on hemodialysis more than 3 years (48/74). Most of the patients did not have a family physician and relied on the nephrologist for health maintenance care (80%) and the treatment of minor acute illnesses (91%). The most common non-renal chronic illnesses were gastrointestinal disease (32%), heart disease (26%), and diabetes (26%). Although referrals to subspecialists occurred in 55% of patients during the preceding year, nephrologists usually provided ongoing management care (gastrointestinal disease 21/24, heart disease 10/19, diabetes 12/19). Over half the women had a Papanicolaou's test within 3 years and 72% had a routine mammogram that, in most cases, had been ordered by the nurse practitioner or nephrologist. Because nephrologists provide primary medical care to the majority of dialysis patients, preventive health care protocols, such as mammography and cancer screening, should be incorporated into the nephrology practice in chronic dialysis units.

We report the results of indirect immunofluorescent (IFI) detection of IgA and IgG antireticulin antibodies (IgA-ARA and IgG-ARA, respectively) in 283 serum samples from pediatric patients with coeliac disease (with and without gluten containing diets), patients with non-coeliac gastrointestinal disease, patients without gastrointestinal disease (control group) and patients with an increased risk for coeliac disease (diabetes mellitus, dermatitis herpetiformis or first grade relatives of coeliac patients). Our results indicate that IgA-ARA is a reproducible marker, with high positive (99-100%) and negative (100%) prediction values, when it is applied to children who have been on gluten containing diets for a long time (more than six months). The IgA-ARA measurement is not applicable in cases of selective IgA deficiency. Although IgG-ARA has a high predictive positive value, its low predictive negative value makes it a poor diagnostic tool. In the risk groups, our results suggest that these antibodies are useful in patient selection for intestinal biopsy.

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.

With electrolyte reference fluid (ERF)00, results from Kodak Ektachem slides for the direct potentiometric assay of sodium in plasma were significantly correlated with results from flame photometry, but also appeared to be systematically higher, especially in hypernatremic patients. Indirect potentiometry with the Technicon RA-1000 yielded intermediate values. In 23 hypernatremic patients with greater than or equal to 6 mmol/L difference in sodium between Ektachem ERF00 and flame photometry, a clinical survey disclosed the frequent association of large between-method differences with renal failure, diabetes mellitus, and gastrointestinal disease. However, there was no correlation between differences in sodium on the one hand and anion gaps or (lipo)protein concentrations on the other, nor did in vitro addition studies implicate metabolites that often accumulate in the above-mentioned disorders. Unlike indirect methods, sodium measurements by direct potentiometry on Ektachem and Corning were influenced by in vitro changes of pH between 7.0 and 7.9. However, in a group of patients that included many acidotic individuals, between-method differences in sodium appeared not significantly correlated with in vivo blood pH. Use of the equitransferant ERF04 on Ektachem strongly diminishes the systematic differences with flame photometry, reduces the pH-dependency of the results to that of the direct Corning method, and brings the mean analytical recovery of sodium to below 95% (instead of 115% previously) without affecting the ability of Ektachem slides to avoid spuriously low results in the presence of increased (monoclonal) protein concentrations.

Between 1959 and Oct. 1990, 307 cases of primary hyperparathyroidism (PHPT) were operated on in our hospital. Among them, 23 cases (7.5%) were asymptomatic chemical type of PHPT, and the incidence of this type has been increasing these days. Various symptoms or signs including urolithiasis, bone disease, cardiovascular disease, gastrointestinal disease, diabetes mellitus and others were associated with PHPT. Especially, as a lethal factor, malignant tumors developed in 14 cases (4.6%); 9 cases of non-medullary thyroid cancer and tumors of other organs. In consideration of these associated disorders, the chemical type of PHPT should be operated prophylactically. In order to reduce operative complications, unilateral exploration is available for the cases of single normally localized adenoma; 85.7% of our 307 cases. Moreover, the positive rate of preoperative localized test by CT and ultrasonography for such adenomas is 78% in the recent 5 years. The predictive values of successful operation by unilateral exploration are 89% in the cases of normally localized single adenoma and 76% in all PHPT.

Rheumatoid arthritis (RA), once considered a benign and nonprogressive disease, is a debilitating condition with serious physical, emotional, and economic consequences. It afflicts approximately 1% of the adult population worldwide; prevalence increases with age, with twice as many women as men affected. In the United States, age, lack of formal education, and lower socioeconomic class correlate with both the incidence and poor prognosis of RA. The patient with RA faces increasing functional disability, the likelihood of work disability within 10 years after the onset of the disease, and a drastic reduction in earnings. Compared with individuals without the disease, patients with RA incur higher medical care costs, increased hospitalization, and a greater number of physician visits. As in the general population, the leading cause of death among patients with RA is cardiovascular disease, and deaths due to malignancy occur at a comparable incidence; however, patients with RA are at greater risk of mortality due to infection, renal disease, respiratory conditions, and gastrointestinal disease. Life expectancy is shorter among patients with RA than in the general population, and survival rates are comparable to those for Hodgkin's disease, diabetes mellitus, stroke, and three-vessel coronary artery disease. Efforts must be made to develop improved therapeutic strategies and rehabilitative programs to improve the quality of life of patients with RA.

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.
