Regulatory policy and abortion clinics: implications for planning.

The practicalities of formulating regulatory policy associated with elective abortion often place public health officials at the center of political controversy. Resulting conflicts can inhibit a rational consideration of long-term objectives in implementing a national policy which assures legal accessibility to all who would select abortion as an alternative to term birth. Regulation which uses primarily structural criteria for monitoring and evaluating services tends to de-emphasize the importanc of contraceptive counseling as a component of abortion services.

Monitoring ventilation during anesthesia.

In patients under anesthesia, ventilation is often monitored less adequately than circulation. A simple method, neglected in adults, is the use of a precordial or oesophageal stethoscope. Respiratory volumes may be measured directly, or inferred from flowrates or pressure changes.

An outcome evaluation of counseling services provided by abortion clinics.

With the reduction in need for elective abortion as a long-term goal, the effectiveness of abortion clinic counseling programs provided at the time of elective pregnancy termination is evaluated using post-abortion contraceptive behavior as a measure. Using eight, free-standing abortion clinics located in Chicago, Illinois a control group design is employed in order to examine the hypothesis that patients attending clinics which provide a structured, comprehensive birth control counseling session at the time of their abortion will show a higher use rate of effective contraceptive methods than those patients attending clinics which do not provide such information. Results support this hypothesis.

Isolation of Sindbis (alphavirus) and Leanyer viruses from mosquitoes collected in the Northern Territory of Australia, 1974.

Mosquitoes collected near Darwin, Northern Territory, in 1974 yielded two virus strains. One was identified as Sindbis virus, not previously isolated from the Northern Territory. The other is antigenically distinct from viruses previously isolated from arthropods in Australia, and the name "Leanyer" is proposed for it.

A clinical comparison of tilidine hydrochloride and pentazocine, given orally for the treatment of postoperative pain.

A controlled, double-blind study involving 250 women was carried out ot assess the efficacy of oral tilidine 25, 50 and 100 mg in treating postepisiotomy pain, and to offer a comparison with oral pentazocine 50 mg. All the analgesics produced significant pain relief. At peak effect tilidine 50 mg produced very similar results to pentazocine 50 mg with tilidine 25 mg producing less, and tilidine 100 mg more pain relief.

Duration of action of analgesic supplements to anesthesia. A double-blind comparison between morphine, fentanyl and sulfentanil.

In a double-blind trial, in a total of 45 patients, sulfentanil was compared with fentanyl and morphine in equipotent doses, as a narcotic supplement to anesthesia. Initially, morphine was shown to have a significantly longer duration of effect than fentanyl and sulfentanil, which for the first 3 doses had similar durations of action to each other. Later doses of fentanyl, however, had an extended effect, presumably because of cumulation.

Familiarity and organization of category terms in semantic memory.

In order to determine production frequencies for various category terms, 219 college students were asked to generate category terms (e.g. Automobiles, Vegetables, Relatives) during a 4-rain period.

Total intravenous anesthesia with etomidate. II. Evaluation of a practical technique for children.

A practical technique for the administration of anesthesia to children is described, using only intravenous agents. Anesthesia was induced using etomidate 0.3 mg/kg, analgesia being provided by fentanyl or pentazocine, and muscle relaxation by suxamethonium or pancuronium.

Total intravenous anesthesia with etomidate. I. A trial in children.

Eighty children, aged from 2 weeks to 14 years, were anesthetized using intravenous agents only. Anesthesia was induced by etomidate 0.3 mg/kg together with atropine and fentanyl 2 to 5 microgram/kg.

Total intravenous anesthesia with etomidate. III. Some observations in adults.

An investigation was undertaken to determine the dosage of etomidate required to maintain sleep in adults undergoing surgery under regional local anesthesia. Premedication of diazepam 10 mg and atropine 0.5 mg was given, and sleep was induced and maintained by intermittent intravenous injections of etomidate 0.

Murray Valley encephalitis virus infection in mosquitoes and domestic fowls in Queensland, 1974.

Field studies during an epidemic of Murray Valley encephalitis (MVE) led to the isolation of MVE virus from a pool of mosquitoes (Culex annulirostris) and a sentinel chicken from Charleville, south-west Queensland. A high proportion of domestic fowls at Charleville had antibody to MVE virus at the beginning of February 1974, in advance of the first case recognized in Queensland and allowing early warning from health authorities. A survey of antibody in domestic fowls in mid-1974 suggested widespread activity of MVE virus in western and east-central Queensland.

A dose-response relationship for etomidate, with some observations on cumulation.

In a within-patient comparison in 30 subjects, sleep was induced before e.c.t.

A clinical assessment of the use of etomidate in children.

Etomidate 0.2 mg/kg i.v.

Some experience of the use of etomidate in children.

Etomidate 0.2 mg/kg was used as an intravenous hypnotic to induce anesthesia in 198 children. If proved to be a safe and effective agent, with no appreciable side-effects on the cardiovascular or respiratory systems.

Ketamine anaesthesia for medical procedures in children.

Ketamine hydrochloride 2 mg/kg, together with atropine 0.2 mg, has been given intravenously on 100 occasions on a general paediatric ward. No serious side effects occurred.

Isolation of arboviruses (Kemerovo group, Sakhalin group) from Ixodes uriae collected at Macquarie Island, Southern ocean.

Eighty-nine pools of ticks (Ixodes [Ceratixodes] uriae White) collected at Macquarie Island (54 degrees 30' S, 159 degrees E) in the Southern Ocean yielded 16 strains of 2 viruses, 1 a "new" member of the Kemerovo group and 1 a "new" member of the Sakhalin group. The names "Nugget" and "Taggert" are proposed for them. Antigenically-related viruses have therefore now been isolated from I.
