The authors relate their experience of integrating screening for African human trypanosomiasis (AHT) caused by T.b. gambiense in a network of multi-purpose health centres at Nioki, Zaire. Since 1983 the health centre nurses have been trained in the laboratory techniques for AHT screening and have been given the essential equipment (microscope, slides, coverslips). The strategy used was that of passive screening of patients who came of their own accord to the health centre: systematic palpation and aspiration of lymph nodes, and examination of wet and/or thick blood films from patients with AHT-like symptoms (fever not responding to antimalarials, headache for over a week, somnolence, arthralgias, pruritus, weight loss). When a trypanosome was detected, the patient was referred to the hospital for confirmation and lumbar puncture. From 1983 to 1987 the proportion of new cases detected by the health centres rose from 0% to 31.1%, while the returns of the mobile teams diminished as the disease regressed. Nevertheless, only 22.1% of the new cases detected by the health centres had normal CSF, as opposed to 64.8% of the new cases detected actively by the mobile teams. These two approaches therefore seem to be complementary: 83% of the new cases detected by the health centres were diagnosed on lymph node aspirates and/or wet films, and it is likely that better use of thick blood films could improve the performance of the health centres.(ABSTRACT TRUNCATED AT 250 WORDS)

The effects of brompheniramine maleate (12 mg twice daily in sustained release form) and terfenadine (60 mg twice daily) on the symptoms and well-being of 16 adults with urticaria with or without dermographism were assessed by symptom questionnaire. Following an initial 2-week period without therapy, each drug was taken for 2 weeks in a randomised double-blind cross-over study. Both drugs produced significant relief of itch and rash but only brompheniramine produced significant drowsiness. Brompheniramine maleate was more effective than terfenadine in the patients with dermographism.

A double-blind study was carried out in 65 patients with seasonal rhinitis to compare the effectiveness and tolerance of terfenadine and dexchlorpheniramine. Patients were allocated at random to receive treatment for 1 week with either 60 mg terfenadine twice daily or 2 mg dexchlorpheniramine maleate 3-times daily. Before and after treatment, patients underwent RAST and skin prick tests for reactivity to pollen and those who were positive also had rhinomanometric measurements made of nasal resistance. Diary cards were used by patients to record the severity of nasal obstruction, rhinorrhoea, sneezing, watery, irritated and red eyes, itching of the nose, throat and eyes, and cough. Details were also kept of the frequency and severity of any side-effects. Pollen counts were taken daily during the treatment period. The results showed that both terfenadine and dexchlorpheniramine produced good or excellent relief of the main symptoms in 78% and 73% of the patients, respectively. There was no significant correlation between the pollen count and reduced symptom severity. Both drugs produced a reduction in total nasal resistance but this was not significantly different from initial values, neither was there a significant difference between treatment. Terfenadine was well tolerated and side-effects incidence was significantly lower (p less than 0.01) than in patients treated with dexchlorpheniramine, particularly so with reference to drowsiness.

The effects of extradural sufentanil 50 micrograms were investigated in 10 normal volunteers. Eight of these were studied at a second session when adrenaline 1:200,000 was added to the sufentanil. Well-defined segmental analgesia developed rapidly after plain sufentanil and lasted approximately 3 h. Respiration was depressed for about the same period and was greatest in the first 2 h, as shown by a 15% increase in PECO2, while the slope and VE50 of the carbon dioxide response curve were depressed by 45% and 55%, respectively. Moderate drowsiness occurred in most subjects, while other side effects of itching, nausea and urinary retention occurred less frequently and were not severe. Addition of adrenaline 1:200,000 intensified segmental analgesia and prolonged duration to 5 h, while side effects were lessened. It is concluded that extradural sufentanil shows considerable promise for clinical use, and that the risk: benefit ratio is improved by adding adrenaline 1:200,000.

The authors studied the effects of epidural sufentanil (0.75 microgram.kg-1) after urologic surgery in 15 children ranging in age from 4 to 12 yr, and in weight from 14 to 47 kg. The onset and duration of analgesia were 3.0 +/- 0.3 and 198 +/- 19 min, respectively (mean +/- SEM). Side effects included pruritus (3/15), nausea and vomiting (5/15), drowsiness (10/15), and urinary retention (1/11). No apnea was observed. Periosteal analgesia and ventilation were studied in eight of the children (mean age 8.6 +/- 0.8 yr). There was significant periosteal analgesia of the tibia (30, 60, 90, and 120 min after injection) and of the radius (60, 90, and 120 min after injection). Resting respiratory rate and tidal volume did not change during the study. Resting minute-ventilation decreased from 6.3 +/- 0.5 l.min-1 preoperatively to 5.6 +/- 0.6 l.min-1 (P less than 0.05) postoperatively, before epidural sufentanil injection; it did not decrease further after epidural sufentanil. Similarly, end-tidal CO2 tension increased significantly from 37.2 +/- 0.7 mmHg preoperatively to 39.9 +/- 1.2 mmHg (P less than 0.05) postoperatively, before epidural sufentanil; epidural sufentanil did not cause a further significant increase in end-tidal CO2 tension. The slope of the CO2 ventilatory response curve decreased significantly from 1.68 +/- 0.12 l.min-1. mmHg-1 preoperatively to 1.10 +/- 0.13 l.min-1.mmHg-1 (P less than 0.01) postoperatively. There were further significant decreases to 0.68 +/- 0.10 and 0.89 +/- 0.16 l.min-1.mmHg-1 30 and 60 min after epidural sufentanil.(ABSTRACT TRUNCATED AT 250 WORDS)

The use of the nonsedating antihistamine terfenadine (60 mg twice daily) in the treatment of chronic idiopathic urticaria and contact urticaria associated with atopic dermatitis was assessed. In patients with chronic idiopathic urticaria, terfenadine was found to be as effective as the traditional antihistamine clemastine in reducing the number of wheals and the severity of itch, without causing drowsiness. A separate study showed terfenadine to be of value in some patients with atopic dermatitis and a history of contact urticaria.

This study was a double-blind, parallel group comparison of terfenadine (TRF) 60 mg b.i.d. and mequitazine (MQZ) 5 mg b.i.d. for 7 days in the symptomatic treatment of acute pollinosis. The trial took place in the same geographic area and during the same pollen season (May-July 85), to ensure homogeneity of the study population. The fourteen investigators participating in this multicentre trial recruited 141 patients (69 TRF; 72 MQZ) suffering from well-documented pollinosis, mainly hay fever and sometimes allergy to tree pollens. Symptoms (nasal itching, sneezing, rhinorrhoea, obstruction, conjunctivitis) and possible somnolence were rated daily using a 4-point rating-scale of 0 to 3 by the patient on a diary card. Assessment of over-all efficacy and tolerability - focusing on atropinic side-effects - was made at the end of the seven-days treatment period by the physician, after reviewing the diary card and questioning the patient. The means score profile of each symptom for the study period was similar with the two treatments. Both had a fast onset of action with the regression of the total symptoms' score being already significant at day 1. Over-all assessment of efficacy at day 7 showed no significant difference between the two treatments. The daily somnolence scores however showed a clear and significant difference between the two drugs: the frequency of moderate to marked somnolence from day 2 to 7 was around 15% with MQZ and around 5% on days 2 to 5 and 0% on days 6 and 7 with TRF, the difference being significant on days 2, 5, 6 and 7.(ABSTRACT TRUNCATED AT 250 WORDS)

To determine the safety, efficacy, and the ventilatory responses to carbon dioxide (CO2) of epidurally administered butorphanol or morphine, 122 healthy women who underwent cesarean section with epidural anesthesia were studied. Patients were randomly assigned to receive one of four epidural regimens for the relief of postoperative pain: 5 mg morphine (n = 32), 4 mg butorphanol (n = 30), 2 mg butorphanol (n = 29), or 1 mg butorphanol (n = 31). Epidural morphine provided satisfactory analgesia with slow onset and long duration of approximately 21 hr. When butorphanol was administered, analgesia of rapid onset was seen with increasing duration and effectiveness observed with increasing dose; approximately 8 hr when using 4 mg. Sixty-two percent of the patients who received morphine had pruritus. Somnolence was the main side effect encountered in patients who received epidural butorphanol. The ventilatory response to CO2 was depressed after morphine and after 2 and 4 mg butorphanol, but the duration of depression was more prolonged after morphine. It is concluded that epidural butorphanol is effective in providing pain relief after cesarean section with minor side effects. However, patients must be observed closely because of possible respiratory depression.

The efficacy of terfenadine, a nonsedating H1 antihistamine, in the management of chronic idiopathic urticaria was compared with chlorpheniramine and placebo in a parallel multicenter trial. Subjects with symptoms of hives for 3 days per week for at least 6 weeks were initially screened and admitted if no identifiable cause for symptoms could be determined. Patients entered a single-blind placebo period, and if hives of moderate severity were present for at least 3 days during the week, they were randomly assigned in a double-blind fashion to take terfenadine, 60 mg twice daily, chlorpheniramine, 4 mg three times a day, or placebo for 6 weeks. Data were analyzed for 122 patients. Those patients receiving both active treatments noted significant improvement in symptoms: pruritus, redness, number of hives, and waking hours during which hives were present, at the end of the first day of therapy. Symptom control by terfenadine was statistically superior to placebo during all 6 weeks, as rated by both patients and investigators. However, statistical significance was not achieved for chlorpheniramine at all observation points. Diphenhydramine was permitted as a relief medication for refractory symptoms and was taken by 52% of subjects receiving placebo, 26% taking chlorpheniramine, and only 9% of patients who were receiving terfenadine. In addition to providing superior symptom control, terfenadine caused less drowsiness and fatigue than chlorpheniramine. Terfenadine is a useful therapeutic agent for primary management of chronic idiopathic urticaria.

The efficacy of naloxone in reducing the incidence of side effects after intrathecal injection of morphine and the effects of maternal naloxone administration on the condition of the newborn were evaluated in 40 patients. Patients in labor were given a 1-mg intrathecal injection of morphine and, 1 hr later, either a 0.4-mg bolus of naloxone, followed by a 0.4-0.6 mg/hr intravenous infusion of naloxone, or an intravenous bolus of saline, followed by an intravenous infusion of saline. Intrathecal morphine provided at least 50% pain relief in 78% of patients given naloxone, and in 82% given saline. Intravenous naloxone significantly decreased the incidence of pruritus during labor and delivery. There was no significant decrease in the incidence of nausea, vomiting, somnolence, dizziness, or urinary retention in patients given naloxone. Despite placental transfer of naloxone, neonatal outcome was not adversely affected. For both groups, maternal beta-endorphin levels decreased significantly with the onset of analgesia and returned to control levels at delivery. We conclude that intravenous infusion of naloxone reduced pruritus after intrathecal injection of 1 mg of morphine for labor pain without lessening analgesia or adversely affecting maternal or neonatal status.
