The outcome of disk surgery in 40 consecutive patients was predicted by pre-treatment assessments of sociodemographic and psychological variables and findings in a standardised orthopaedic and neurological examination. The pre-surgery variables that proved to be associated with outcome criteria six months post surgery by means of a multiple stepwise regression procedure were selected for discriminant analyses, using three outcome criteria: functional status, patient evaluation of the outcome, and vocational rehabilitation. ⋯ No prediction was possible for postoperative pain behaviour and postoperative orthopaedic and neurological status. Significant predictors were time off work before surgery, active search for information about disease and surgery, presence of conditions that reinforce pain behaviour, and cognitive variables indicating helplessness.

Abdominopelvic actinomycosis associated with the use of an intrauterine contraceptive device (IUD) is described. The diagnosis is usually made after exploratory laparotomy for severe abdominal pain and signs of an acute abdomen, or for prolonged lower abdominal pain and findings consistent with pelvic malignancy. 3 women aged 33, 44 and 52 years, respectively, are presented.

Comparative StudyInduction of labour in nulliparas with poor cervical score: oxytocin or prostaglandin vaginal pessaries?
In a previous study nulliparas with poor cervical score (less than 5 out of 10) had a 43.5% Caesarean section (CS) rate of which 55% were for failed induction when labour was induced by artificial rupture of membranes and oxytocin infusion. In this study induction of labour by 2 doses of 3 mg prostaglandin E2 (PGE2) vaginal pessaries, 4 hours apart, and if necessary by artificial rupture of membranes and oxytocin infusion 24 hours later, resulted in a CS rate of 23.7% of which 38.9% were for failed induction. The latter regimen resulted in a significantly lower CS rate compared with labour induced by oxytocin infusion and rupture of membranes without the use of prostaglandins (p less than 0.001). ⋯ In those who did not start labour and needed rupture of membranes and oxytocin infusion 24 hours after the first pessary, 34 (47.9%) had a good cervical score (greater than or equal to 6 out of 10) and 37 (52.1%) had a poor cervical score (less than or equal to 5 out of 10) at the time of amniotomy. The CS rates in these groups were 8.8% and 48.6% respectively (p less than 0.001). In nulliparas with poor cervical score induction is better performed with vaginal prostaglandin pessaries in order to reduce the high CS rate associated with artificial rupture of membranes and oxytocin infusion.

Brazil has one of the highest rates of caesarean section in the world. Patterns of caesarean sections were studied in a cohort of 5960 mothers followed from 1982 to 1986 in southern Brazil. ⋯ Socioeconomic status and requests for sterilisation by tubal ligation were important underlying factors. 9.4% of the women were sterilised during a caesarean section (3.7% in the lowest income group and 20.2% in the highest). 31% of women who had had their first child by a caesarean section and who were having a second operative delivery were sterilised. The high rates of caesarean sections and accompanying sterilisations reflect the lack of appropriate reproductive and contraceptive policies in the country.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of various physiologic and psychomotor parameters in patients sedated with intravenous lorazepam, diazepam, or midazolam during oral surgery.
Intravenously administered lorazepam (0.05 mg/kg), diazepam (0.25 mg/kg), and midazolam (0.1 mg/kg) were compared for sedation during oral surgery under local anesthesia. Sixty patients were randomly allocated into three groups in this double-blind, parallel study. The results from this trial show that all three drugs provide satisfactory sedation. ⋯ At 1, 1.5, and 2 hours after arrival in the recovery room, an inversion of groups took place, with the lorazepam group taking significantly longer for their tests than the other two groups. Significantly more improvement in anxiety levels was found at 10 minutes postdrug for the patients who had received diazepam and this tended to remain so on arrival in the recovery room. When compared with the other two groups, significantly more patients in the lorazepam group reported giddiness/dizziness and significantly more in the diazepam group reported pain on injection.
