Postoperative protein metabolism: effect of nursing elderly patients for 24 h after abdominal surgery in a thermoneutral environment.

We have studied the effect of intraoperative body heat conservation and 24-h thermoneutrality on postoperative whole body protein turnover using stable isotope methodology in a group of elderly patients undergoing colorectal surgery for rectosigmoid adenocarcinoma. Two groups of eight patients were studied. One group (control, or cold) received routine intraoperative and postoperative care. All patients in the second group (warmed) were maintained at normothermia during anaesthesia and surgery; these patients were nursed after surgery in a warm room (ambient temperature 28-30 degrees C) for a period of 24 h. General anaesthesia, surgical care and nutritional support were similar in both groups. A constant nutritional intake, based on nitrogen 0.1 g kg-1 day-1 and energy 20 kcal kg-1 day-1, was provided orally for 7 days before surgery and i.v. after operation for 4 consecutive days. Whole body protein breakdown and synthesis, as assessed by stable isotope methodology, increased significantly 2 and 4 days after surgery in both groups (P less than 0.01), but the increase in protein breakdown in the warmed group on day 2 was significantly less than that in the cold group (P less than 0.05). The increase in leucine oxidation in the warmed group on the 2nd day after surgery was not significant, and was less than the increase observed in the cold group (P less than 0.05). However, by the 4th day, leucine oxidation was enhanced significantly in both groups (P less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)

Congenital limb deficiency: maternal factors in pregnancy.

Maternal factors in pregnancy were examined in a case-control study of 155 children with limb deficiencies (longitudinal and transverse) born 1970-1981 inclusive and 274 matched normal controls. Vomiting of pregnancy was associated with an increased risk of longitudinal limb reduction defects. Gestational bleeding has long been known for its association with perinatal mortality, low birth-weight and prematurity; limb deficiencies have also been noted. In the present study the pattern of bleeding differed between women in the transverse and longitudinal groups, with the possibility of a causal role for bleeding in the aetiology of longitudinal but not transverse defects. There was a significant statistical risk associated with respiratory infections comparable with the reported association of congenital limb deficiency and influenza from Finland.

Outpatient stabilization programme--an innovative approach in the management of diabetes.

An outpatient stabilization programme for diabetic patients was established to overcome the disadvantages of inpatient treatment. The day to day management of patients was carried out by experienced nurse/educators under the supervision of physicians. The telephone was used extensively for communication between the patients and staff of the Diabetes Centre. In a 12 month period, 73 patients were commenced on insulin and 83 patients (62 on insulin) had their diabetic control re-stabilized. In both groups of patients there was a significant fall in glycosylated haemoglobin levels indicating improved metabolic control. Results were similar to those for patients admitted to hospital for stabilization. There are important social and economic benefits from the avoidance of repeated hospitalization.

The innocent bystander. Doxylamine/dicyclomine/pyridoxine and congenital limb defects.

The antinausea drug combination, doxylamine/dicyclomine/pyridoxine (Debendox or Bendectin [US] ), has been withdrawn from the market because of litigation based upon charges that it causes congenital limb defects. To investigate this allegation, the pregnancy histories of mothers of 155 limb-deficient children, born between 1970 and 1981, have been compared with those of mothers of 273 matched normal controls. There was no significant difference between the pregnancy histories of mothers of case children and those of mothers of control children in respect of reported frequency of morning sickness, the use of doxylamine/dicyclomine/pyridoxine, the date of commencement of its intake, the duration of intake, or its dose. The relative risk of limb deficiency in children of mothers exposed to this drug is estimated to be 1.1 with confidence limits of 0.8-1.5. No risk of congenital limb defects was found to be associated with the use of this drug.

Pelvic endometriosis and tubal inflammatory disease.

The incidence of tubal inflammatory disease in women with endometriosis who had undergone surgery was compared with that in women who had undergone similar operative procedures but who did not have endometriosis and with that in a group of clinically healthy women undergoing tubal sterilisation. The incidence of tubal inflammatory lesions was much higher in all women who had undergone surgery than in those undergoing sterilisation, but there was no difference in the incidence of tubal lesions between those women with endometriosis and those not suffering from this disease. Women with endometriosis and tubal inflammatory disease did not have a significantly lower mean gravidity than did those with healthy tubes. It is concluded that there is no specific association between endometriosis and tubal inflammation and that tubal inflammatory disease is unlikely to be a significant factor contributing to infertility in endometriosis.

Repair of massive inguinal hernia: with pneumoperitoneum and without using prosthetic mesh.

There was an unusual need for preoperative induction of an artificial pneumoperitoneum in two cases of inguinal hernia. Both hernias were very large and associated with extensive intertrigo. Daily insufflations of air were performed for 13 and 11 days, with the patients compensating for this increased intraabdominal pressure over this time. Operation with removal of the ipsilateral testicle, cord, and scrotum was then straightforward and convalescence uneventful. The pneumoperitoneum allowed a repair to be effected without using a prosthetic mesh.

Cyclic AMP regulation of active chloride transport in the rectal gland of marine elasmobranchs.

Active transport of chloride in the salt secreting rectal gland of the dogfish Squalus acanthias is markedly stimulated by the addition of theophylline (0.01 to 5 mM) or dibutyryl cyclic AMP (0.05 mM) during in vitro perfusion. The effect occurs promptly and may persist for two hours. Specific hormonal effectors have not yet been identified. The isolated perfused rectal gland thus offers a unique opportunity to examine the cellular mechanisms of active chloride secretion.
