Clinical Trial Controlled Clinical Trial
Evaluation of a new antihelminthic for trichuriasis, hookworm, and stronglyloidiasis.
Mebendazole was tested in a double-blind trial for its efficacy in the treatment and control of enteric helminths. One hundred and twenty-two children from a community near the Gulf of Carpentaria, and from a community in Cape York Peninsula in northern Queensland were divided into two equal groups to receive a course of either mebendazole or placebo after the identification of one or more intestinal helminths in a single pretreatment specimen of faeces. Between the tenth and twentieth days after a four-day course of treatment, three specimens of faeces were collected from each child. ⋯ No cases of Ascaris lumbricoides infestation were present. No side effects or adverse reactions to the drug were noted and patient acceptance was excellent. Mebendazole appears to be a safe drug for use in the treatment of human parasitic intestinal nematode infestations, and should be especially useful in the treatment and control of trichuriasis.

A modified critical-incident analysis technique was used in a retrospective examination of the characteristics of human error and equipment failure in anesthetic practice. The objective was to uncover patterns of frequently occurring incidents that are in need of careful prospective investigation. Forty-seven interviews were conducted with staff and resident anesthesiologists at one urban teaching institution, and descriptions of 359 preventable incidents were obtained. ⋯ Overt equipment failures constituted only 14 per cent of the total number of preventable incidents, but equipment design was indictable in many categories of human error, as were inadequate experience and insufficient familiarity with equipment or with the specific surgical procedure. Other factors frequently associated with incidents were inadequate communication among personnel, haste or lack of precaution, and distraction. Results from multi-hospital studies based on the methodology developed could be used for more objective determination of priorities and planning of specific investments for decreasing the risk associated with anesthesia.

Comparative Study[Comparison between intra and para cervical anaesthesia in therapeutic abortion (author's transl)].
Therapeutic abortion during the first trimester of pregnancy was carried out as an out-patient procedure under local anaesthesia in 40 women. The intracervical injection of 1% mepivacaine resulted in satisfactory freedom from pain just as the paracervical injection. ⋯ The dilatation of the cervical canal was the determining factor for pain during the procedure. The intracervical and the paracervical local block are equally suitable for out-patient therapeutic abortion in our series.

The mortality associated with 240 483 anaesthetics administered over 10 years at Groote Schuur Hospital, Cape Town, is reported. The frequency of death to which anaesthesia contributed was 0.22 per 1000 anaesthetics (compared with 0.33 per 1000 in the previous 10 years). These deaths were responsible for 2.2% of the total mortality from surgery. Two-thirds of the "anaesthetic" deaths were attributable to (in order of frequency): (a) hypovolaemia; (b) respiratory inadequacy following myoneural blockade; (c) complications of tracheal intubation; (d) inadequate postoperative care and supervision.

World Health Organization studies of prostaglandins versus saline as abortifacients. A reappraisal.
The World Health Organization (WHO) Task Force on the Use of Prostaglandins for the Regulation of Fertility has sponsored a series of randomized clinical trials and case-series investigations to assess the effectiveness and safety of prostaglandins as abortifacients. Our reanalysis of the WHO studies found the prostaglandins to be faster and more hazardour than hypertonic saline as intraamniotic abortifacients. ⋯ For gestations of greater than or equal to 17 weeks, the occurrence of live births in prostaglandin-induced abortions has produced serious legal and ethical problems in the United States. Until the effectiveness and safety of other prostaglandins regimen approach that of D&E, we feel that D&E should be the index of comparison against which newer methods of inducing abortion are tested.
