Purified C. perfringens type A enterotoxin fed orally in an amount of 5 mg caused both vomiting and diarrhea in the monkey only when the gastric juice had been neutralized. Exposure of enterotoxin to pH 4.0 or below rapidly destroyed the activity. All three monkeys receiving sodium bicarbonate and 2.4 X 10(10) viable cells grown in DS medium developed diarrhea, and only one of them vomited once. The diarrhea lasted for 13, 18 and 19 hr. The symptoms were similar to those reported in human cases of C. perfringens food poisoning. These results have verified the general notion that C. perfringens food poisoning should be categorized as a true "intravital intoxication". The reversed passive hemagglutination test detected enterotoxin directly in most fecal samples. This method may be applicable for diagnosis of human cases of C. perfringens food poisoning. Neither enterotoxin nor anti-enterotoxin was detected in serum samples taken from any monkey up to 21 days after the challenge. We are tempted to conclude, therefore, that no significant amount of C. perfringens enterotoxin is absorbed from the intestine.

A research has been carried out on a total of 121 persons with survival post-drug shock (DS), which registered 192 DS. Mention should be made of their predominance in the feminine sex (85 per cent) and their maximum frequency between the ages of 21-50 (average age 34). DS was the first adverse reaction to drugs in 71 per cent of the cases. Therefore DS unpredictability is very frequent. A retrospective study suggested the role of risk factors which should help the doctor to prevent DS (personal allergic antecedents, antecedents of adverse reactions to drugs, neuroses, disorders of endocrine glands, feminine sex, etc.). In 1970, the clinical concept of shock imminence (SI) was formulated and it is applied to various etiologies (drugs, insect stings, food). The existence of SI was identified in the case history of 14 per cent of the persons with DS. SI is a syndrome which includes all clinical manifestations with imminent potential of transformation into shock condition, and represents the stage precursory to the setting up of shock. The utility of SI diagnosis is maximum if it also includes the causal factor (e.g. SI by penicillin or aspirin). The clinical image of SI may vary from the monosymptomatic aspect (urticaria, vomiting, diarrhoea, headaches, etc.) to the one with complex symptomatology (mixed form). Usually the symptoms are dramatic and depend on the administration of a certain drug (often in SI of allergic origin) or of various drugs (mainly on non-immunologic form). The absence of vascular collapse differentiates SI from shock. Differential diagnosis is more difficult in border cases with a slight diminution of blood pressure. SI can be diagnosed especially in several circumstances: when the first adverse drug reaction is dramatic; when the first allergic-type reaction to a drug occurs; when the repetition of drug reactions is amplified in intensity or frequency; when it occurs in persons with risk factors. The differential diagnosis of SI is made with a crude or minimum shock and with pre-shock condition. The advantages of SI diagnosis are the institution of efficient treatment with rapid recoverability and the prevention of subsequent shock to the respective drug.

Midtrimester abortion was induced in 94 of 100 patients at 16 to 24 weeks' gestation by the extra-amniotic administration of 1170 microng of prostaglandin F2alpha (PGF2alpha) every 10 minutes. The number of prostaglandin doses varied from 16 to 24 depending on the patient's response to the prostaglandin. The median abortion time was 10.0 hours, and 82.0% of the patients aborted within 24 hours. Overall, 68.0% of the patients failed to expel the placenta within one hour of abortion of the fetus. Vomiting and diarrhea occurred among 42.0 and 17.0% of the patients, respectively. Compared with the intra-amniotic administration of a single 50 mg dose of PGF2alpha, the extra-amniotic procedure was associated with similar side effect rates, a higher rate of incomplete abortion, and a significantly shorter abortion time.

Cases of otitis media in infants under 12 weeks of age were reviewed to delineate the frequency, clinical features, and etiologic agents involved. Tympanocentesis was performed in 42 infants, 0 to 5 weeks of age, and in 17, from 6 to 11 weeks of age. The most common symptoms were irritability/lethargy (69%), fever (52%), cough (36%), vomiting (21%), diarrhea (20%), tachypnea (20%), and anorexia (18%). Associated illnesses were present in 33 (54%) of the patients, the most common being pneumonia (9), bronchiolitis (7), meningitis (6), conjunctivitis (4), and omphalitis (4). No peripartum infections or severe perinatal problems were found. Common respiratory pathogens were the predominant etiologic organisms, but coliform organisms were identified in 18% of the infants under 6 weeks of age. Cultures were sterile or grew organisms of questionable pathogenicity ("nonpathogens") in 39% of specimens. Since the signs and symptoms of otitis media in children less than 12 weeks of age are nonspecific and frequently associated with other major illnesses, the physician caring for these infants needs to be more aware of this disease and the therapeutic problems it presents.

The effect of prostaglandin E2 (PGE2) release rate from an intravaginal suppository on induced abortion was investigated in a randomized, double-blind study of 71 women who were 7-22 weeks pregnant. 2 dosage forms were compared. Base A was selected to provide a more hydrophilic character than base B. 6 vaginal suppositories, inserted at 4-8 hour intervals as deemed necessary for the clinical progress of abortion, were available for each patient. If abortion did not occur within 48 hours, the trial was discontinued. When time for 50% dissolution of PGE2 (t50%) was plotted as a function of pH for the 2 suppository formulations, the curve for base A was sigmoidal in shape, showing a more rapid release of PGE2 and pH increase. In contrast, base B demonstrated a t50% value of 30 hours which was independent of pH. This independence suggested the hypothesis that the clinical performance of base B would be more uniform than a base A formulation and would exhibit a longer duration of biologic action. Use of base A was found to produce a slight increase in the frequency of successful abortions (79% with base A versus 70.3% with base B). There were no significant differences in the mean times from treatment initiation to complete abortion, the number of incomplete abortions, or failure to abort between the 2 study groups. There was a nonsignificant trend toward reduced total drug use in the base A group. Examination of side effects indicated that women receiving PGE2 in base B had a greater but nonsignificant tendency to experience nausea (62.2% in group B, 58.8% in group A) and vomiting (83.8% group B, 76.5% group A); however, there was a significantly greater amount of diarrhea in the base B group (70.3%) than in the base A group (41.2%). It was concluded that there are no major differences in abortifacient efficiency or the general incidence of side effects when PGE2 therapy in 2 dosage forms is compared. However, a more hydrophilic base, which exhibits a more rapid release of PGE2, appears to slightly reduce side effects and efficacy.

A new viral disease (Maridi haemorrhagic fever) occurred in the South Sudan in 1976. It was obviously identical with an epidemic which occurred at the same time in Zaire. The virus is morpologically closely similar to the Marburg virus. During the Maridi epemic 124 of 238 patients died (52%). Characteristic symptoms were fever and headache (100%), diarrhoea (83%), retrosternal pain (82%), vomiting (68%), haemorrhages (62%), morbilliform or vesicular rash (52%). At post-mortem there were changes in liver, kidney, myocardium and lungs, similar to those in the Marburg virus disease, as were those observed in bone marrow and peripheral blood. Despite these analagous findings, the clinical course and results of immunofluorescence indicate that it is a new disease. The epidemic ended after suitable isolation measures had been taken. There was no specific treatment but in some cases convalescent plasma and interferon were tried. The disease is transmitted among humans by direct contact or by contact with blood or excreta of patients. No animal reservoir has been found. It is possible for this disease to be imported also into countries with a modorate climate.

A clinical trial comparing 2 vaginal dose schedules of 15(S)15-methyl prostaglandin F2alpha (PGF2alpha) methyl ester (4 or 6 mg) for preoperative dilatation is described. The trial included 28 patients at 8-12 weeks gestation. Vaginal pessaries containing either 1.0 mg (15 patients) or 1.5 mg (13 patients) of the prostaglandin analogue were administered every 3 hours (maximum, 4 doses). The success rates for the 2 groups were 93% and 10% respectively. A 96.4% overall success rate is comparable to that achieved in other studies. 60% of the patients aborted before the planned vacuum aspiration. Minor side effects, primarily vomiting and diarrhea, occurred in approximately 80% of the cases and were more prominent with the higher dose pessary. Since this higher dosage produced an unacceptably high occurrence of gastrointestinal side effects, the lower dosage of 4 mg is preferable. It is concluded that vaginal administration of 15(S)15-methyl PGF2alpha methyl ester is highly effective for preoperative dilatation of the cervix before suction curettage abortion.

25 patients--19 to 73 years old--who underwent maxillofacial operations, received Spontavix for 10 to 12 days via a nasogastric tube. In 20% of the patients nausea, vomiting, diarrhea and/or abdominal pain occurred and disappeared after finishing nutrition with Spontavix. Mean frequency of defecation was 0.5/patient/24 hours. Body weight, serum electrolytes, blood gases, pH and base excess in the arterial blood, urea-nitrogen, hemoglobin and albumin content of the blood did not change significantly. Lipids in the serum increased insignificantly without leaving normal limits. During nutrition with Spontavix serum transaminases (SGOT, SGPT) showed a statistically significant increase which is believed to be caused by general anesthesia.

Much clinical experience has been gained in the use of the glucose/electrolyte oral solutions in the treatment of acute diarrhea. Those patients who are in shock or too weak to drink need intravenous fluids to correct their total deficit. With isotonic polyelectrolyte fluids rehydration may be achieved in 2-4 hours. Subsequently, most of these patients can be given oral fluids to replace continuing stool loss. Patients who are not in shock and who are sufficiently strong to drink at the outset nearly always can be rehydrated with oral fluids alone. Vomiting is most likely caused by acidosis and volume depletion, and these can be corrected in severely dehydrated patients by intravenous therapy and by oral therapy in those not in shock and able to drink by oral therapy. Proponents of oral glucose/electrolyte therapy for diarrhea, like other proponents of new treatments, have great visions of its benefits to the world, yet these visions require validation. The biggest problem will be getting glucose and electrolytes to where they are most needed -- at the level of home and village.

The successful termination of 19 consecutive late 1st and 2nd trimester pregnancies using a combination of intravenous prostaglandin E2 (PGE2) and oxytocin (Syntocinon) is reported. PGE2 (5 mg in 500 ml of 5% glucose) was initially infused at the rate of 2.5 mcg/minute and then increased to 5 mcg/minute after half an hour. The infusion was increased to a maximum of 10 mcg/minute. Oxytocin was infused 2 hours after the PGE2 at a constant rate of 128 mU/minute. Mean total dose of PGE2 used was 5.9 mg at an overall rate of 6.1 mcg/minute. Average induction/delivery interval was 16 hours, with only 1 patient taking more than 24 hours. Abortion was complete in 13 cases (68%). Vomiting occurred in 13 women; pain was minor and was controlled by pethidine. Mild and transient thrombophlebitis was also reported. There were no reported cases of diarrhea and or cervical damage. Compared to the use of intravenous PG alone, PG given intraamniotically alone or with intravenous oxytocin, and PG given extraamniotically alone or with intravenous oxytocin, this study shows that a combination of intravenous PGE2 and oxytocin at the dose level described is closer to meeting all the desired criteria for the acceptability of any abortion method (ease and safety of administration, side effects, lengths of induction delivery interval, and effectiveness in terms of success rate and uterine evacuation).
