Inpatient extracorporeal shockwave lithotripsy for treatment of gallbladder stones has not previously been compared with open cholecystectomy in terms of cost-effectiveness. In a randomised controlled trial, 163 patients, stratified by gallstone bulk (over 4 cm3 or not), were randomised to lithotripsy or cholecystectomy (38 large-bulk and 27 small-bulk cholecystectomy; 37 large-bulk and 61 small-bulk lithotripsy) and followed up for 1 year. Both treatments gave significant health gains in terms of a reduction in episodes of biliary pain, improved perceived health status, and symptom relief, but few differences between treatments were found. There was some evidence that biliary-pain episodes were less severe after cholecystectomy. Cholecystectomy patients also had greater improvements in mean health gain for three related symptoms: vomiting, feeling sick, and fatty-food upset. However, there were no differences between groups in perceived health status. Among lithotripsy patients, health gain was not related to stone clearance. Lithotripsy was more expensive than cholecystectomy, principally because of the costs of the inpatient stay and adjuvant bile-salt therapy. Conventional lithotripsy appears at least as cost-effective as cholecystectomy for patients with small-bulk stones but less cost-effective for those with large-bulk stones. To some extent treatment choice can be guided by patient preference.

The study, supported by program MZ-XVII, was carried on 4567 inhabitants of the area of Szczecin (2350 females and 2217 males). The population was chosen randomly, according to a simple drawing scheme. All subjects were clinically examined using standardised questionnaires. In 3468 persons (including 1807 girls and women, 1661 boys and men) apart form clinical examination, the assessment of thyrotropin, thyroxine and triiodothyronine in serum and frequency of antithyroglobulin antibodies and antithyroid membrane antibodies were evaluated. The data indicate that 94% of children in Szczecin's region received the prophylactic dose of iodine, mostly between the 1st and the 5th of May 1986. Only 17% of the adults received iodine. The most common preparation was Lugol solution given in a single dose. Among all persons who received iodine, only in 5% of subjects the side effects were noted (mostly in children), including symptoms of gastrointestinal tract (vomiting, abdomen pain) and occasionally intrathyroid side effects (thyroid pains). In examined population the high frequency of thyroid enlargement, mainly in women (up to 43-44% at the age group 30-50 years) was found. The frequency of clinical diagnosis of thyroid disease was higher in women than in man (most often the diffuse goiter, rarely the nodular goiter). The frequency of thyroid enlargement and clinical diagnosis of thyroid disease was not dependent on prophylactic iodine intake. The iodine prophylaxis did not influence on thyroid hormones and TSH serum levels and on frequency of antithyroid antibodies.

The palliation of bone pain is a common clinical problem once metastatic prostate cancer has escaped from hormonal control. This retrospective study compares the results of treatment using hemibody irradiation (HBI) at the Royal Marsden Hospital (27 cases) with isotope therapy using the bone-seeking isotope strontium-89 (89Sr) at Southampton General Hospital (51 cases). Prior to analysis patients were matched for potential prognostic factors (performance status, bone scan extent of disease, age, histology and duration of hormone response) to minimize the effect of treatment selection bias. Pain control assessed at 3 months was similar for HBI and matched 89Sr cases, with 63% and 52% respectively showing some benefit. Median survival was similar for these groups at 20 and 21 weeks respectively. The unmatched 89Sr group, which had more favourable prognostic factors, had a better outcome with 96% showing improvement in pain and with a median survival of 59 weeks. Subsequent univariate analysis demonstrated that performance status and extent of disease on bone scan were of overriding importance in determining outcome. Transfusion requirements were higher for the HBI group than for the matched 89Sr group (50% and 25% respectively) but other bone marrow toxicity was similar. Despite routine anti-emetic therapy 37% of patients treated with HBI had some nausea or vomiting. Although expensive, 89Sr appears as effective a treatment option as HBI. Response is most likely with either approach when patients have a good performance status and a limited extent of disease.

Prophylactic administration of analgesics before surgery can decrease the intraoperative anaesthetic requirement and decrease pain during the early postoperative period. In a double-blind, placebo-controlled study involving 90 healthy ASA physical status I or II children undergoing bilateral myringotomy, we compared the postoperative analgesic effects of oral acetaminophen and ketorolac, when administered 30 min before induction of anaesthesia. Patients were randomized to receive saline (0.1 ml.kg-1), acetaminophen (10 mg.kg-1) or ketorolac (1 mg.kg-1) diluted in cherry syrup to a total volume of 5 ml. Anaesthesia was induced and maintained with halothane and nitrous oxide via a face mask. Postoperative pain was assessed by a blinded observer using an objective pain scale. The three study groups were similar with respect to demographic data, duration of anaesthesia and surgery, induction behaviour, oxygen saturation, incidence of postoperative emesis and, recovery times. The ketorolac group had lower postoperative pain scores and required less frequent analgesic therapy in the early postoperative period compared with the acetaminophen and placebo groups. In contrast, there were no differences in pain scores or analgesic requirements between the acetaminophen and the placebo groups. We conclude that the preoperative administration of oral ketorolac, but not acetaminophen, provided better postoperative pain control than placebo in children undergoing bilateral myringotomy.

Amongst 876 cases suffering from ascariasis 662 cases were managed conservatively and 214 cases were treated by surgery. Surgical complications were found to be more common in males in the age group of 6-10 years. Principal clinical features included pain abdomen (99.54%), constipation (80.25%), vomiting (67.46%), abdominal distension (47.03%), palpable worm masses in abdomen (35.50%), visible peristalsis (27.63%), worms in vomitus (24.20%) and palpable worm clumps on rectal examination (20.09%). Principal clinical diagnosis were worm colics (48.74%), sub-acute intestinal obstruction (27.74%), acute intestinal obstruction (11.42%) and acute intestinal obstruction with strangulation (5.71%); rest of the cases included worm cholecystitis (2.63%), obstructive jaundice (1.71%), bile peritonitis (0.91%), intestinal perforation (0.68%) and acute appendicitis (0.46%). Surgical procedures performed were milking of worms (34.12%), resection anastomosis of small intestine (23.36%), enterotomy with removal of worms (16.36%), cholecystectomy with T-tube drainage (12.15%), cholecystectomy (8.41%), appendectomy (1.87%), resection anastomosis with excision of Meckel's diverticulum (1.40%), repair of intestinal perforation with peritoneal toilet (1.40%) and cholecystectomy with choledochoduodenostomy (0.93%).

This article discusses the findings of a study of pre-adolescent children to determine if the mode of presentation of appendicitis had changed over the past 10 years, if the incidence of perforations decreased with age, and if diagnosis related groups (DRGs) impacted the length of hospital stay. The charts of 42 children under the age of 12 years who were discharged from two inner-city hospitals with a diagnosis of acute appendicitis from 1980 to 1989 were reviewed. There were 20 blacks and 22 whites, 26 males and 16 females with an average age of 7.31 years (range: 2 to 11 years). Over 95% of patients presented with right lower quadrant pain, 78% with guarding, 80% with a positive psoas sign, 93% with a positive Rovsing's sign, and 65% with rectal tenderness. Over 85% of patients had a history of nausea, vomiting, and anorexia. The mean duration of pain was 52.8 hours and the mean temperature was 99.6 degrees F. The mean white blood cell count was 18,176 +/- 4682 for whites versus 14,615 +/- 5459 for blacks. At surgery 15/42 (36%) of patients had a perforation, 11 of whom had positive wound cultures. Escherichia coli was recovered in all 11 of these patients. The average duration of pain in the perforated group was 50.9 hours, and the average age was 7 years. Eleven of these patients had normal bowel sounds on admission. Only 31% of the total cohort had a fecalith identified by pathology. The average postoperative length of stay was 6.5 +/- 2.5 days before the initiation of DRGs and 7.5 +/- 3 days afterward.

This study compared naloxone and nalbuphine when administered for treatment of side effects after epidural morphine, 5 mg, given for postcesarean analgesia. Patients requesting treatment for pruritus or nausea randomly received, in a double-blind fashion, up to three intravenous doses of either naloxone 0.2 mg (group 1; n = 20) or nalbuphine 5 mg (group 2; n = 20). The incidence of vomiting, the severity of nausea and pruritus, and the degree of sedation and pain were assessed before and 30 min after each dose. The first dose of nalbuphine decreased the incidence of vomiting (P < 0.005) and the severity of nausea and pruritus (P < 0.01), whereas naloxone caused no significant changes. Sedation scores increased after nalbuphine (P < 0.05) and remained unchanged after naloxone, whereas pain scores increased after naloxone (P < 0.01) and were unchanged after nalbuphine. Eighteen patients in group 1 and 12 in group 2 received a second dose, and 8 and 4 patients, respectively, a third dose. Other than decreased pruritus after the second dose with both drugs, no further changes occurred. We conclude that nalbuphine is superior to naloxone for the treatment of side effects after epidural morphine. However, persistent symptoms may require supplemental therapy, as repeated doses proved less effective than the initial dose.

Although epidural opioids frequently are used to provide postoperative analgesia, several articles have suggested that the analgesia after epidural fentanyl is similar to that after an equal dose of fentanyl given intravenously. To address this issue further, 29 postthoracotomy patients were studied in a randomized, double-blinded trial comparing a lumbar epidural fentanyl infusion with an intravenous fentanyl infusion for analgesia, plasma fentanyl pharmacokinetics, and respiratory effects for 20 h postoperatively. In all patients in both groups, good analgesia was achieved (pain score less than 3, maximum 10) over a similar time course, although the patients receiving epidural infusion required a significantly larger fentanyl infusion dose than did the patients receiving intravenous infusion (group receiving epidural fentanyl infusion: 1.95 +/- 0.45 micrograms.kg-1.h-1; group receiving intravenous fentanyl infusion: 1.56 +/- 0.36 micrograms.kg-1.h-1; P = 0.0002). The time course for the plasma fentanyl concentrations was similar in the two groups, and plasma fentanyl concentrations were not significantly different at any sampling period (T7-T20; group receiving epidural fentanyl infusion: 1.8 +/- 0.5 ng/ml; group receiving intravenous fentanyl infusion: 1.6 +/- 0.6 ng/ml; P = 0.06). Similarly, calculated clearance values for the two groups were not significantly different (group receiving epidural fentanyl infusion: 0.95 +/- 0.26 l.kg-1.h-1; group receiving intravenous fentanyl infusion: 0.87 +/- 0.25 l.kg-1.h-1; P = 0.3). Both groups demonstrated a similar degree of mild to moderate respiratory depression postoperatively, which was assessed with continuous respiratory inductance plethysmography and sequential arterial blood gas analysis. Side effects (nausea, vomiting, pruritus) were mild and did not differ between groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Ondansetron is a highly potent and selective antagonist at 5-HT3 receptors. Its anti-emetic actions were first revealed by its ability to antagonize retching and vomiting induced by chemotherapy and radiotherapy in animals and man. Subsequently, the availability of labelled 5-HT3 receptor ligands allowed identification of 5-HT3 receptors, located at highest densities in the area postrema, nucleus tractus solitarius (NTS), in other areas of the brain, and on afferent terminals of the vagus nerve. Postoperative nausea and vomiting may be caused by various factors: the anaesthetic, associated drugs, the surgical procedure, movement of the patient, sex, weight and pain. These factors mediate their effects via the higher brain circuits, the vestibular nuclei, the chemoreceptor trigger zone in the area postrema, or the upper gastrointestinal tract via the vagus nerve, influencing motor and visceral emetic outputs in the hind-brain. It is hypothesized that ondansetron blocks nausea and vomiting by 5-HT3 receptor antagonism at two specific sites: (i) centrally, in the area postrema/NTS; and (ii) peripherally on vagus nerve terminals. The absence of other pharmacological effects of ondansetron ensures an absence of side-effects.

Of 138 endoscopically or surgically confirmed cases of gastric ulcer, 102 (74%) were males and 36 (26%) females. Both sexes were affected most commonly in the 6th decade of life. Pain, vomiting and gastrointestinal bleeding were the major presenting symptoms, with a median duration of 6 months. Cigarette smoking was the most common (44%) addiction and 10% were on analgesics or nonsteroidal anti-inflammatory drugs (NSAID). Family history of ulcer was uncommon (2%) and no predilection for any blood group was noted. Among males 53% were skilled workers while 94% of females were housewives. Forty five percent patients were migrants from India and the rest belonged to different provinces of Pakistan. Presentation and behaviour of different sites of gastric ulcers though varied but the results were not significant. Healing rates with H2 receptor antagonists were 33% at 4 weeks and 78% at 8 weeks.
