Eastern equine encephalitis (EEE) was diagnosed in a flock of emus in southeastern Louisiana. The outbreak involved juvenile and adult breeders ranging in age from 20 to 36 months, with an attack rate of 76% and a case fatality rate of 87%. The diagnosis was confirmed by isolation and characterization of the viral agent, and by detection of EEE antibody in two recovered emus. High mortality was preceded by marked depression, hemorrhagic diarrhea, and emesis of blood-stained ingesta. On postmortem examination, hemorrhagic enteritis and multiple petechia of viscera were observed. Microscopic changes included severe necrosis of hepatocytes, intestinal mucosa, and necrotizing vasculitis of the spleen and lamina propria of the intestine. No nervous system lesions were observed. This outbreak occurred concurrently with EEE in horses and was attributed to unseasonably heavy rainfall with an abundance of arthropod vectors and proximity to free-living reservoir host species.

Ondansetron is a 5-HT3 receptor antagonist which is effective and well tolerated as an antiemetic for emesis induced by cancer chemotherapy and radiation therapy, and in the prevention and treatment of postoperative nausea and vomiting. Ondansetron is rapidly absorbed after oral administration (tmax 1.9 h) with an absolute bioavailability of around 60%. Its terminal elimination half-life is 3.5 h and it is extensively hepatically metabolized. Plasma clearance is 0.38 litre h-1 kg-1 and volume of distribution is 1.8 litre kg-1. Plasma clearance is reduced by age (31% reduction) and hepatic failure (80% reduction in severe failure). In patients undergoing general anaesthesia there is a slight prolongation of terminal half-life, which is not of clinical significance. Ondansetron is very well tolerated in volunteer studies. Headache, mild abdominal pain, and constipation occur infrequently. There is no evidence for effects of ondansetron on cardiac function (electrocardiogram, cardiac output, blood pressure and heart rate), and haemostatic function in volunteers and patients. Respiratory depression induced during general anaesthesia is not potentiated by ondansetron. No drug interactions have been noted with temazepam, atracurium, alfentanil and alcohol in man. There are also no interactions seen in animal studies using pentobarbitone, morphine, neostigmine, prednisolone and diazepam.

We studied the effect of a low-dose intrathecal morphine (0.1 or 0.2 mg) in postoperative pain relief and the incidence of side effects. Two hundred and fifteen patients scheduled for transvaginal hysterectomy were divided into 3 groups according to intrathecal morphine doses: M1 (morphine 0.1 mg N = 75), M2 (morphine 0.2 mg N = 69) and C (control N = 71). A standard mid-line lumbar puncture was performed using a 25-gauze needle in the L3/4 interspace. Preservative-free morphine hydrochloride mixed in hyperbaric tetracaine solution was administered intrathecally. Pain relief was significantly greater for the first 24 hrs in groups M1 and M2 compared with group C. Respiratory depression was not seen in any groups. The incidence of vomiting was about 40% in all groups. We conclude that intrathecal morphine 0.1-0.2 mg is useful for pain relief after transvaginal hysterectomy and accompanies no major side effects.

Drug-induced acid-base disorders may be classified into four categories with respect to the mechanism. 1. Metabolic acidosis is induced by a large acid loads incurred from exogenous sources (e.g. NH4Cl, or toxin ingestion) or endogenous acid production (e.g. generation of ketoacids or lactic acids by alcohol or phenformin) or base loss (e.g. abuse of laxatives). 2. Metabolic alkalosis results from exogenous bicarbonate loads (e.g. milk-alkali syndrome) or effective extracellular fluid contraction, potassium depletion plus hyperaldosteronism (e.g. vomiting, diuretics, or licorice). 3. Renal tubular acidosis is induced by the drugs which mainly impair proximal and/or distal tubules (e.g. vitamin D, NSAID, acetazolamide or amphotericin B). 4. Respiratory acidosis or alkalosis results from drug-induced respiratory center depression or neuromuscular impairment (e.g. anesthetic, sedative overdosage or curare) or hyperventilation (salicylates, paraldehyde, epinephrine, or nicotine).

The neuroendocrine response to L-5-hydroxytryptophan was compared in 37 prepubertal children who met the Research Diagnostic Criteria for major depressive disorder with that in 23 normal children with no lifetime history of any psychiatric disorder and very low rates of depression in both first- and second-degree relatives. Intravenous L-5-hydroxytryptophan (0.8 mg/kg) was given over a 1-hour interval after preloading with oral carbidopa, an inhibitor of peripheral but not central L-5-hydroxytryptophan metabolism. L-5-Hydroxytryptophan, a precursor of serotonin, increases serotonin turnover in the central nervous system when given after carbidopa. Seven (19%) of the 37 children with major depressive disorder and two (9%) of the 23 normal children had nausea or vomiting and therefore did not complete the full infusion. They were subsequently excluded from data analysis. After this stimulation, prolactin, cortisol, and growth hormone secretion were compared between diagnostic groups. The depressed children secreted significantly less cortisol (effect size, 0.70) and significantly more prolactin (effect size, 0.83). There was a sex-by-diagnosis interaction in prolactin response to L-5-hydroxytryptophan and, on examination, the prolactin hypersecretion was seen in depressed girls but not in depressed boys compared with same-sex controls. There was no significant stimulation of growth hormone in either group. These findings are consistent with dysregulation of central serotonergic systems in childhood major depression.

Twenty-two studies on the effects of psychological treatment on cancer patients are reviewed. Only studies that compared one or more experimental conditions with at least one control group have been considered. The studies were evaluated with respect to a) research methods, b) psychological interventions, and c) results. Tailored counseling has been shown to be effective with respect to distress, self-concept, (health) locus of control, fatigue, and sexual problems. Structured counseling showed positive effects with respect to depression and distress. Behavioral interventions and hypnosis were effective with respect to specific symptoms such as anxiety, pain, nausea, and vomiting. The research methods, interventions and results of the studies are reviewed critically. Several recommendations for future research are made.

A search of medical records at the Georgia Animal Poison Information Center over a 19-month period revealed 240 cases of dog and cat exposure to nonsteroidal anti-inflammatory drugs (NSAID). The most common NSAID consumed were ibuprofen, acetaminophen, aspirin, and indomethacin. The most common clinical signs of toxicosis were vomiting and diarrhea, CNS depression, and circulatory manifestations. Pets are at risk from NSAID toxicosis through administration by the owners or accidental consumption of improperly stored drugs.

The techniques of anesthesia for extracorporeal shock wave lithotripsy of urinary calculi and the associated complications in 600 treatments with the second generation lithotriptor Siemens Lithostar were studied. General anesthesia was used in 17 treatments (2.8%) and epidural anesthesia was applied in 73 (12%), primarily in children and patients in need of simultaneous surgical auxiliary procedures. A total of 510 treatments (85%) was performed with a combination of local infiltration anesthesia and supplementary intravenous opiates. In 65% of the cases only 2 injections of opiates were sufficient for pain relief. There were no complications in 394 treatments (77%) and minor complications, such as arrhythmia (9.2%) and nausea/vomiting (7.6%), were easily treated. Respiratory depression was observed in 10 cases (2%) and this potentially dangerous complication was associated with simultaneous administration of opiates and midazolam. Only 9 treatments (1.8%) had to be terminated due to complications. It is concluded that most treatments of urinary calculi with this second generation extracorporeal shock wave lithotriptor can be performed with local infiltration anesthesia combined with supplementary short-acting opiates intravenously for pain relief and sedation. When administering supplementary midazolam for sedation the risk of respiratory depression should be considered.

Tablet buprenorphine hydrochloride when administered to 34 primigravida women sublingually in a dose of 6 micrograms/kg body weight during the first stage of labour, the analgesic action started 30 minutes after administration of drug and the analgesic action increased gradually and reached its peak level 3 hours after administration of drug. Analgesic action continued throughout the first stage of labour when the duration after administration of drug was 9 hours. In one case maximum analgesic action did not persist after 9 hours. The average time of delivery was 5.88 hours having cervical dilatation of 3.1 (+/- 0.13) cm and the progress of labour was not delayed by the drug. There was no cardiorespiratory depression of the subjects. None complained of nausea or vomiting. There was no change in foetal heart rate and Apgar scoring of neonates revealed the average value of 9.71 at 1 minute and 9.94 at 5 minutes.

Hypnosis has proven to be extremely valuable in the treatment of cancer patients. Specific applications include: establishing rapport between the patient and members of the medical health team; control of pain with self-regulation of pain perception through the use of glove anesthesia, time distortion, amnesia, transference of pain to a different body part, or dissociation of the painful part from the rest of the body; controlling symptoms, such as, nausea, anticipatory emesis, learned food aversions, etc.; psychotherapy for anxiety, depression, guilt, anger, hostility, frustration, isolation, and a diminished sense of self-esteem; visualization for health improvement; and, dealing with death anxiety and other related issues. Hypnosis has unique advantages for patients including improvement of self-esteem, involvement in self-care, return of locus of control, lack of unpleasant side effects, and continued efficacy despite continued use.
