Patterns of diagnostic testing in the academic setting: the influence of medical attendings' subspecialty training.

Internists with subspecialty training (subspecialists) constitute the majority of the medical faculty members and the test-ordering behavior of these subspecialists influences how house officers and students solve clinical problems. To assess whether test-ordering patterns are influenced by the ward attendings' subspecialty status, we identified the number of gastrointestinal endoscopic procedures, bone marrow procedures and exercise stress tests that were ordered on 9608 patients admitted to a medical service during a 3 year period. The patient management was supervised by attendings, 8 of whom were generalists and 37 of whom were subspecialists. House officers supervised by generalists ordered 23% fewer gastrointestinal procedures, 47% fewer bone marrow procedures, 43% fewer exercise stress tests and 29% fewer total procedures than house staff supervised by subspecialists (P--not significant, P less than 0.001, P less than 0.05 and P less than 0.01, respectively). House officers perceive a difference between the test-ordering patterns of subspecialists and generalists. They attribute this difference to post-residency training and believe that the use of more tests indicates a greater compulsion toward an exhaustive evaluation.

Prognostic value of an abnormal P terminal force in lead V1 at onset of acute myocardial infarction.

The presence of an abnormal P terminal force of the P wave in lead V1 (PTFV1) was demonstrated on the initial electrocardiograms in 69 of the 200 patients with transmural acute myocardial infarction. 61.5% of the total cases with a lethal outcome during hospitalization belonged to this group. The mortality of the patients who presented this ECG sign of left atrial hypertension at the onset was 53.7%, thus differing significantly from that in patients without the sign (22.1%). The PTFV1 anomaly has a prognostic value in patients without complications as well as in those with heart failure at the onset of the disease. The appearance during hospitalization of major arrhythmias and disturbances of conduction and of sudden death is significantly correlated to the presence of abnormal PTFV1 on the admission electrocardiograms.

Lactose malabsorption in Thai infants and children: effect of prolonged milk feeding.

More than one-third of Thai infants were lactose malabsorbers soon after birth and the percentage of lactose malabsorption increased with age. Beyond 4 years of age, all Thai children studied were lactose malabsorbers. Continued milk supplementation over the study period did not affect the ability to digest lactose in the amount given in the load test. Since the milk-supplemented group of children tended to have better weight gain and few undesirable gastrointestinal symptoms, it seems milk feedings can be used to advantage even among populations with a record of high lactose intolerance.
