Cimetidine suspension in patients with stage 0 gastro-oesophageal reflux disease.

One hundred and twenty-five patients with symptoms of heartburn and acid regurgitation but without endoscopic abnormalities were randomized to receive 200 mg cimetidine suspension four times daily or placebo for two weeks. Daily dairy cards were kept to evaluate the frequency and degree of symptoms. At two weeks cimetidine was significantly more effective than placebo. It is concluded that placebo suspension has a considerable effect on gastro-oesophageal reflux disease symptoms, but cimetidine suspension provides significantly better relief.

Reappraisal of the clinical and etiologic significance of immunoglobulin deviations in autoimmune hemolytic anemia ('warm type').

56 patients with autoimmune hemolytic anemia ('warm type') (AIHA) were investigated for immunoglobulin deviations. Of these, 43 were repeatedly analyzed (mean 4 times). The mean observation time was 20 months. The immunoglobulin values were correlated with clinical (degree of hemolysis) and serological (immunoglobulin class of autoantibodies; strength of antiglobulin reaction) parameters and statistically evaluated by variance analysis. Although no significant deviations of immunoglobulins in AIHA were found as compared to a normal control group, the immunoglobulin disturbance most frequently seen was an elevation of IgM. This is interpreted as a possible lack or functional impairment of immunoregulatory T cells in AIHA.

[The lh-rh-test in men with fertility disorders (author's transl)].

89 mal patients with fertility disorders underwent a test with 50 mug synthetic LH-RH. The basal levels of FSH and LH are elevated in patients with azoospermia, with testicular atrophy, varicocele and Klinefelters syndrome. They increase with age. After stimulation with LH-RH the highest relative peaks (maximal value divided by control value) of LH are seen younger patients, in those with varicocele, and oligozoospermia. The FSH-values do not differ significantly between these groups. Low relative peaks of LH are seen in older patients. In Klinefelter's syndrome the relative peaks of FSH and LH are significantly lowered.

Activation of intravascular coagulation by endotoxin: the significance of granulocytes and platelets.

The importance of granulocytes and/or platelets in endotoxin-induced generalized intravascular coagulation was studied as well as thrombocytopenic rabbits. Neutropenia and thrombocytopenia were induced by oral administration of busulphan. Generalized intravascular coagulation, as indicated by renal glomerular microclot formation, was initiated by two intravenous injections of endotoxin. Granulocyte counts before the second injection of endotoxin were most significantly related to activation of intravascular coagulation whereas platelet counts either before the first or second injection of endotoxin were not definitely related to the activation process. Renal glomerular microclots occurred in rabbits after two injections of endotoxin even when the platelet counts were between 500 and 5000/mul. These experiments indicated that granulocytes but not platelets are essential to the activation of endotoxin-induced intravascular coagulation.

Oxygen consumption, heart rate, respiratory rate and rectal temperature in healthy newborns during the first two hours after birth.

A report is made on the continuous registration of oxygen consumption, heart rate, respiratory rate and rectal temperature in 32 neonates during the first two hours of life. A short account of the registration technique is given. A comparative study shows, that oxygen consumption, heart rate and respiratory rate fall during the period of observation, whereas the rectal temperature rises. 26 out of the 32 neonates demonstrated a approximately linear fall of each of the oxygen consumption values during the period of observation. There is a similar relationship, which is statistically verified, between the oxygen uptake and heart rate. Oxygen consumption and heart rate can be correlated with each other after the first 60 minutes of life. This close and direct relationship between the oxygen consumption and the heart rate, an important parameter of the heart and circulatory system, stresses clearly the importance of the continuous registration of oxygen consumption for monitoring the general condition of the neonate. A change from this situation means a risk for the neonate which must be clarified by blood-gas analysis. A continuous registration of oxygen uptake for the surveillance of the neonate includes numerous vital functions and appears to be a more suitable parameter than single parameters which include only partial functions. The application of the method is simple and safe for the infant.

The effect of pindolol on exercise-induced cardiac acceleration in relation to plasma levels in man.

The correlation between the beta receptor blocking activity of pindolol and plasma level was studied in 8 subjects after a 10-mg oral dose. Exercise tachycardia was markedly reduced over a period of at least 6 hr. Significant effects were recorded 30 min after the drug. For each individual there was a close correlation between log plasma level and beta blockade. The regression lines were parallel as shown by analysis of covariance; the intercepts, however, were significantly different. It can be concluded that there is a correlation between plasma level and beta adrenergic blockade by pindolol, but the data failed to establish in different individuals the blood levels necessary to achieve effective adrenergic blockade.

[Diagnostic errors and their reasons in tumors and preblastomatoses of the skin. Results of a statistical evaluation].

Clinical and histological findings and other available data of 6 521 skin excisates were compared with regard to differential diagnosis. It appears from our findings, that "naive" experience must be replaced by secured knowledge concerning frequencies of wrong diagnoses in definite situations, possible causes of errors, age-, sex-, and local distribution of different skin tumours. This knowledge may be a contribution to the improvement of clinical diagnoses.
