Dominant inheritance of cleft of the soft palate.

A family is described with apparent dominantly inherited complete cleft of the soft palate. The complexity of the genetics of oral clefts is emphasized. The inheritance of oral clefts is complex. Different modes of inheritance have been reported for clefts both simple and in syndromes (Gorlin et al., 1971), but the majority of cases of nonsyndromal clefts appears to have a low, yet significant, genetic component (Fraser et al., 1974). This report describes a family with cleft of the soft palate which appears to follow a dominant pattern of inheritance. To our knowledge this is the first reported instance of dominantly inherited cleft palate.

Teaching with audiovisual recordings of consultations.

The experience gained from two years' teaching with audiovisual recordings of consultations of both undergraduates and postgraduates is presented. Some basic teaching rules are suggested and further applications of the technique are discussed.

Evaluation of the single radial haemolysis (SRH) technique for rubella antibody measurement.

Sera from 1258 individuals have been tested by four laboratories for rubella antibody by both the haemagglutination-inhibition and single radial haemolysis techniques. There was good agreement between the results obtained by the two methods. Although sheep red blood cells were used in the single radial haemolysis plates, no problems were encountered with sera from patients with infectious mononucleosis. The single haemolysis technique was found to be simple, convenient, and reliable, and suited to the rapid screening of large numbers of sera to assess susceptibility to rubella in the context of a vaccination campaign. However, since the technique does not detect anti-rubella IgM, it should not be used as the only test to investigate suspected recent infection.

Isosorbide dinitrate and intra-aortic balloon pumping in preinfarctional angina. Effects on central circulatory dynamics.

The dynamics of the central circulation were measured by a radionuclidic technique in 18 men with high-risk preinfarctional angina who received therapy with isosorbide dinitrate (n equals 18), intra-aortic balloon pumping (n equals 8), or both (n equals 8). Administration of 5 mg of isosorbide dinitrate sublinqually was associated with a reduction in stroke volume index (SVI), cardiac index (CI), systemic arterial blood pressure, and left ventricular end-diastolic volume (LVEDV) and with increased left ventricular ejection fraction (LVEF). Intra-aortic balloon pumping did not alter SVI or CI, but decreased systolic blood pressure and LVEDV and increased LVEF and diastolic blood pressure. The combination of therapy with isosorbide dinitrate and intraaortic balloon pumping resulted in decreased SVI, systolic blood pressure, and LVEDV and increased LVEF. Thus, therapy with isosorbide dinitrate reduced left ventricular preload, and intra-aortic balloon pumping reduced blood pressure, which resulted in a decreased LVEDV and an increase in LVEF. Therapy with isosorbide dinitrate and intra-aortic balloon pumping act to alter central circulatory dynamics in favor of reducing myocardial oxygen demand.

Intranasal betamethasone valerate in seasonal rhinitis.

A double-blind study comparing betamethasone valerate and placebo aerosols was carried out in 40 patients with a history of seasonal allergic rhinitis and positive skin tests to grass pollens. Analysis of the symptoms recorded on a daily record card for a period of one month indicated that the mean monthly symptom-score was lower for all symptoms in the group on active therapy and that this reached statistical significance for the symptom of sneezing. Significantly more antihistamine tablets were used by the placebo group as compared with the active group (p less than 0-05). The patients' assessment of their treatment was in favour of betamethasone valerate (p less than 0-05). No clinically significant side-effects were associated with the treatment, which was well tolerated.

Effects of a low-oestrogen oral contraceptive on urinary excretion of luteinizing hormone and ovarian steroids.

The urinary gonadotrophin and ovarian steroid excretion pattern was studied in five women taking an oral contraceptive formulation consisting of mestranol 50 mug and norethisterone 1 mg. Both the pretreatment and post-treatment cycles were normal. The ovulatory peak of luteinizing hormone (LH) during the treatment cycles was uniformly suppressed, but LH continued to be excreted within the normal range. In one fifth of the treatment cycles there was a pronounced and sustained rise of oestrogen output in the absence of ovulation, and in many of the other treatment cycles oestrogen levels suggested that active ovarian steroidogenesis was taking place.
