Just at a time, when practical education and post-graduate training is really a permanent problem, it is necessary to pay attention again and again to the rare problems, which also appear in the doctor's office. They are by far not only "rare and useless": The recognition by the physician may be vital for the patient. Four examples from daily practice illustrate the significance of rarities in the physician's office as a permanent challenge.
A few facts about the smoking problem, strategies and possibilities of nicotine withdrawal in practice and thoughts on prevention of recurrence of smoking are reviewed. This presentation is intended as support to the antismoking campaign of the Swiss Health Office and the Federation of Swiss Physicians.
Using a medical district association meeting as an example, the problem of 'alcohol and doctors' is considered. According to numerous authors, doctors belong to a special alcohol risk population, although hardly anyone else is better acquainted with the risk of alcohol. With some courage and improved knowledge of the problem, one should be able to prevent a friend or a colleague from excessive alcohol abuse. The prognosis is by no means bad.
The effect of 300 mg cimetidine q.i.d. on ulcer healing was studied in a controlled double-blind clinical trial of 71 in-patients with duodenal ulcer. Healing occurred in 48.5% of patients in the cimetidine group after two weeks, and in 20.6% in the placebo group (P less than 0.05). The healing rate was 88% in the cimetidine group at four weeks, 79.4% in the placebo group. Only during the first day was ulcer pain significantly reduced in the cimetidine-treated patients. Neither basal nor pentagastrin-stimulated acid and pepsin secretions were affected by 17-day administration of cimetidine. The drug had to be withdrawn in two patients because of elevated serum-creatinine levels. There was no other untoward effect.
In a controlled double-blind clinical trial of 39 in-patients with gastric ulcer the effect of cimetidine on ulcer healing, ulcer pain and pentagastrin-stimulated acid and pepsin secretion was measured. A faster healing rate in the cimetidine group was statistically not significant. Cimetidine had no effect on ulcer pain and pentagastrin-stimulated acid and pepsin secretion. There were no serious untoward reactions.

A new simple method of treating urinary stress incontinence is to fix a fibrin implant vaginally to the bladder neck and upper urethra. The support provided by the implant is maintained after its resorption by the fibrous tissue which replaces it. The two-year cure rate in 85 patients was 93 per cent.
According to this study human skin scrapings bind anti-human IgE and IgM immunoglobulins as demonstrated by fluorescent miscroscopy; this is not dependent on the atopy of the subject.

Anti-thymocyte globulin is strongly reactive with platelets as measured by flow cytometric analysis. This reactivity appears to be independent of human leukocyte antigen (HLA) phenotype, is dose-dependent with saturation of platelet binding sites readily achieved with concentrations of horse anti-thymocyte globulin (ATG) at 0.25 mg per ml, and cannot be blocked with human anti-PLA1 antibody nor with heat-aggregated human IgG. Results of immunoblot studies after electrophoresis of platelet membrane proteins are consistent with the proposal that horse ATG contains antibodies specific for platelet glycoproteins V and IIa.
A case of neonatal isoimmune thrombocytopenia (NIT) is described in which maternal platelet antibody levels decreased during the course of pregnancy. It is suggested that if this disorder is clinically suspected, maternal serum should be assessed for anti-platelet specificity using immunoblot analysis.
