Why search for congenital defects?

The causation of congenital malformation is receiving increased study. In Canada, epidemiologic surveys are being planned, based upon the institution of Provincial Registries to which physicians and other agencies will voluntarily report cases coming to their attention. The literature in regard to prevalence studies of congenital cardiac defects in school children is reviewed. Over the past 25 years, studies employing the proposed technique demonstrated a rising trend, from 1.4 per 1000 to 2.6 per 1000. By contrast, specific surveys for congenital cardiac defect carried out by expert personnel using radiographs and electrocardiographs, resulted in essentially uniform rates, approximating 5 to 6 per 1000. It is concluded that the latter is a superior technique of epidemiologic survey over the "Central Registry" method, and should command a due proportion of health resources directed towards congenital malformation research.

Determining when to refer periodontal patients--clinical guidelines.

As part of the examination and evaluation of the patient, it is the dentist's responsibility to evaluate the periodontal tissues for the presence or absence of periodontal disease. If the practitioner finds that periodontal disease is present and is unwilling or unable to accurately diagnose and/or treat the type or extent of the disease, the dentist must offer the patient the opportunity to be evaluated by a practitioner who can complete the examination and diagnostic process.

Lithium treatment of depressed and nondepressed alcoholics.

We assessed the efficacy of lithium carbonate in the treatment of 457 male alcoholics in a double-blind, placebo-controlled Department of Veterans Affairs Cooperative Study. Alcoholics either without depression or with a history of major depression, current major depression, or dysthymic disorder were studied. Two hundred eighty-six alcoholics without depression and 171 alcoholics with depression began the 52-week outpatient study; 172 alcoholics (60.1%) without depression and 108 alcoholics (63.2%) with depression completed the study. Among both all alcoholics who began the study and a subgroup who completed the study, no significant differences between alcoholics who took lithium and those who took placebo were found for the following outcome measures:number of alcoholics abstinent, number of days of drinking, number of alcohol-related hospitalizations, changes in rating of severity of alcoholism, and change in severity of depression. Similarly, no significant differences were found when only the 82 alcoholics compliant in taking lithium and the 89 alcoholics compliant in taking placebo were considered. In our study, lithium treatment did not affect the course of alcoholism in either depressed or nondepressed alcoholics.
