Pyridostigmine bromide, a reversible inhibitor of acetylcholinesterase (AChE), is effectively used as a pre-treatment to organophosphate intoxication. Previous studies have shown that an oral dose of 30 mg twice a day produces a sufficient inhibition of the enzyme activity (20-40%) without causing any significant adverse effect. During the Persian Gulf war pyridostigmine was taken for the first time under a chemical warfare threat. We searched for symptoms and complaints that may be related to the medication. Our survey included 213 soldiers who completed a questionnaire regarding possible symptoms and their severity. AChE inhibition level was compared between groups of soldiers with and without complaints. The most frequent symptoms were nonspecific and included dry mouth, general malaise, fatigue and weakness. Typical effects, such as nausea, abdominal pain, frequent urination and rhinorrhea, were infrequent. The severity of the symptoms was generally mild. The symptoms appeared around 1.6 h after taking the medication and recurred after each intake. No correlation was found between levels of cholinesterase and type or severity of complaints. Anxiety, which accompanies wartime, may have contributed to the appearance of significant symptoms. Further investigations concerning the effects of pyridostigmine ingestion under stressful conditions are warranted.

Forty-two surgical patients were given epidural tramadol for control of postoperative pain. They were randomly assigned to three groups: group 1 (n = 15), in which 25 mg of tramadol were given; group 2 (n = 13), in which 50 mg of tramadol were given; and group 3 (n = 14), in which 75 mg of tramadol were given. When the patients complained of wound pain, epidural tramadol was given. Heart rate, blood pressure, respiratory rate, oxygen saturation (SpO2), sedation scale, motor blockade, verbal rating scale, subjective grading, and visual analogue pain scale (VAPS) were measured and recorded before the tramadol administration, at 5 and 15 min, and at 1, 2, 4, and 8 h after the tramadol administration. Only 26.6% of the patients in group 1 had significant relief of pain. The rest of them needed at least one incremental dose of 25 mg of tramadol. The baseline VAPS of the patients in group 2 was 8.9 +/- 2.0. It became 5.46 +/- 3.0 (p greater than 0.05) 15 min after tramadol was given, and dropped further to 1.9 +/- 1.8 (p greater than 0.05) 2 h later. The average duration of pain relief was 12.0 +/- 5.9 h. In group 3, the initial VAPS was 8.14 +/- 1.9. It decreased to 4.28 +/- 1.8 (p greater than 0.05) 15 min, and further dropped to 1.7 +/- 0.9 (p greater than 0.05) 2 h following tramadol administration. The average duration of pain relief was 11.3 +/- 4.8 h. The common side effects of tramadol such as dizziness, nausea, and dry mouth, were most frequently found in group 3.(ABSTRACT TRUNCATED AT 250 WORDS)

Fifty-eight patients undergoing restorative dental treatment at Guy's Hospital had been previously allocated on the basis of clinical assessment, including that of their dental anxiety, to treatment under local anaesthetic alone or in combination with i.v. midazolam or inhalation nitrous oxide. They were tested before and after dental treatment to determine their memory of dental procedures and changes in mood and bodily symptoms. The patients allocated to the midazolam treatment had significantly higher pre-treatment scores on the Bond & Lader mood factors of "anxiety" and "discontent". All the groups showed significant pre- to post-treatment reductions in sweating, palpitations, restlessness, dry mouth, muscular tension, nausea, loss of appetite and upset stomach and the extent of these reductions were not different for the different treatments. Midazolam treatment resulted in significantly greater reductions in self-ratings of bodily symptoms of anxiety, shaking and trembling compared with the control (local anaesthetic) group. Nitrous oxide resulted in a significant reduction in irritability, compared with controls. Both midazolam and nitrous oxide significantly reduced the patients' memory of the dental procedures and the impairments in memory were independent of any changes in anxiety or sedation. Of the items remembered there were no differences between the groups in their ratings of how well explained, how pleasant or unpleasant, or how painful the procedures were.

The efficacy and tolerability of the selective 5-HT reuptake inhibitor fluvoxamine were compared with the tricyclic dothiepin in 52 elderly (age greater than 64 years) hospital patients in a multi-centre double-blind randomised trial. Patients met DSM-III criteria for 'major depressive episode' and scored greater than 29 on the Montgomery Asberg Depression Rating Scale (MADRS) after a one-week placebo baseline. Active treatment was for six weeks. The dosage of both drugs was 50 mg nocte for three days, 100 mg nocte for the remainder of the first week, thereafter increasing to a maximum of 200 mg/day according to response/tolerance. MADRS scores improved by 63.5% with fluvoxamine and 60.0% with dothiepin; there were no significant differences between treatments at any assessment. Nausea, dizziness, headache, somnolence and constipation in both groups, plus dry mouth and asthenia in the dothiepin group were more frequent than single reports. Two patients in each group discontinued treatment owing to unwanted effects. There were no clinically significant changes in haematological, biochemical or cardiovascular parameters.

In a six-week double-blind randomized trial, preceded by a one-week period of single-blind placebo treatment, the efficacy and the side-effects of fluvoxamine (100-300 mg/d) (n = 24) and maprotiline (50-150 mg/d) (n = 24) were compared in moderately depressed outpatients with DSM-III Major Depression (n = 22) or Dysthymic Disorder (n = 26). Efficacy was measured by means of the Hamilton Depression Rating Scale, the Zung Depression Selfrating Scale, and a Clinical Global Impression of Severity Scale. Side-effects were evaluated by an Adverse Event Inventory and a Psychosomatic Symptom Scale. A statistically significant improvement was achieved in both treatment groups but success rates were modest: in both groups, 29% of the patients achieved a clinically significant improvement after six weeks of treatment. After six weeks of treatment, no difference in efficacy was found between fluvoxamine and maprotiline. Nausea was the most common complaint in the fluvoxamine group, while in the maprotiline group, it was dry mouth and constipation. One maprotiline-treated patient developed a convulsive attack.

Physician education in cancer pain management is seriously deficient. Many problems occur with opioids simply because of therapeutic ignorance. Opioid side effects are best prevented by using morphine as the drug of first choice for severe pain. Anticipation and prevention of opioid side effects avoids most problems. Physicians need to be aware of how to transfer patients from one opioid to another or from one route of administration to another. Side effects common in clinical practice are constipation, nausea/vomiting, dry mouth, and sedation. The importance of the issues of tolerance, dependence, and respiratory depression have been exaggerated.

The safety and efficacy of nortriptyline and fluoxetine were compared in a double-blind, randomized, multicenter 5-week trial involving 205 outpatients with acute major depression of moderate severity. Seventy-two nortriptyline and 84 fluoxetine patients completed at least 2 weeks of medication and were included in the efficacy analysis; all patients were evaluated for side effects. Average total scores on the Hamilton Rating Scale for Depression (HAM-D) for both treatment groups declined from 22-23 at baseline to 11.5 at the conclusion of the 5-week period. At Week, 5, 71% of nortriptyline patients and 65% of fluoxetine patients were much or very much improved. Fluoxetine was associated more frequently with nausea (p less than .05), while nortriptyline was associated more frequently with dry mouth (p less than .05). These results are discussed in the context of selecting between nortriptyline and fluoxetine for a particular depressed patient.

In 1988-1989 two outbreaks of trichinosis were recorded. The first case was group disease developed in 3 members of the family. The source of infection was rissoles rolled in cabbage leaves [correction of goloubets] stuffed with minced pork. The second outbreak affected 13 persons who had eaten home-made pork sausage and fat. All the patients displayed fever, weakness, muscular pain, subcutaneous fat edema, predominantly of the face. The patients suffered from dry mouth, thirst, deteriorated appetite, exanthema, eosinophilia, more occasionally, nausea, vomiting, abdominal pain and diarrhea. Trichinosis was confirmed serologically. Vermox therapy (300 mg per day) was performed for 7 to 12 days. The disease was severe, moderate and mild in 5, 7 and 4 patients, respectively. A brief abstract from a case record of a patient with severe trichinosis complicated by allergic myocarditis is presented. The severity of the disease was associated with the infecting dose and the time at which etiotropic therapy was started. Vermox had a good therapeutic effect and caused no adverse events.

Emesis in chemotherapy containing Cisplatinum (DDP) is still a therapeutical dilemma. Emesis and nausea cause the cessation of a potential curative therapy in up to 10% of patients treated with DDP. We studied the antiemetic effectiveness of the selective Serotonin (5HT3)-receptor-antagonist Ondansetron (GR 38032F, Glaxo) in patients receiving high dose platinum chemotherapy. All patients suffered from severe emesis and were refractory to any standard antiemetic regimen (Metoclopramid). We studied the efficacy of the new drug against acute and delayed emesis following platinum chemotherapy. All adverse events are listed. Thirty four courses (n = 17 patients) of a platinum-containing regimen were analyzed so far. A sufficient antiemetic efficacy was observed in 56% of the courses. In 32 of 34 course (94%) the patients preferred the new drug compared with the standard antiemetic regime (Metoclopramid). In most cases only minor adverse events--which do not require any medical therapy--occurred. The most common adverse events were headache, constipation, dry mouth, abdominal discomfort and elevation of liver enzyme level without any clinical symptoms. One patient needed bowel surgery for severe constipation based on widespread intra-abdominal carcinosis.

Two hundred forty-one elderly depressed patients entered the 8-week, double-blind phase of this parallel-group, multicenter study; 161 patients were randomized to receive sertraline (50-200 mg/day) and 80 were randomized to receive amitriptyline (50-150 mg/day). Among evaluable patients, there were no statistically significant differences between treatments in any of the primary efficacy variables: change in total Hamilton Rating Scale for Depression (HAM-D) score (17 items), percentage change in HAM-D score, change in HAM-D Item 1, change in Clinical Global Impressions (CGI) Severity score, change in the Depression Factor of the 56-item Hopkins Symptom Checklist, and the CGI Improvement score at the last visit. Similar results were obtained using data from all patients (intention-to-treat analysis), except that amitriptyline was superior in HAM-D Total score (p = .044). The two drugs produced a similar degree of response: on the basis of the HAM-D criterion, 69.4% of sertraline patients and 62.5% of amitriptyline patients responded, and, on the basis of CGI criterion, 79.5% of sertraline and 73.4% of amitriptyline patients responded. Twenty-eight percent of the sertraline patients withdrew from the study because of a treatment-related side effect and 2.5% (4) because of a laboratory abnormality. In comparison, 35% of the amitriptyline patients withdrew because of treatment-related side effects. Sertraline was associated with a statistically lower frequency of somnolence, dry mouth, constipation, ataxia, and pain and a higher frequency of nausea, anorexia, diarrhea/loose stools, and insomnia; thus, anticholinergic effects were less common and gastrointestinal effects were more common with sertraline than with amitriptyline.(ABSTRACT TRUNCATED AT 250 WORDS)
