The author states that aside from two major digestive psychosomatic conditions, peptic ulcer and ulcero-hemorragic colitis, one only encounters in the adult a widespread psychosomatic pathology, that is to say: 1 degree phenomena of hysterical conversion (gravidic vomiting for example); 2 degrees digestive phenomena concomitant with emotional reactions (diarrhea and anxiety, hypersecretion and anger, constipation and depression etc.); 3 degrees digestive manifestations accompanying anxiety neurosis; 4 degrees authentic functional diseases, such as the irritable colon corresponding to a well defined personality structure. The author concludes this article by some considerations of psychosomatic symptoms observed by the psychoanalyst; he specifically relates the role of the body barrier, the implication of reality and finally the very particular fantasies found in these psychosomatic patients.

Idiopathic hypoparathyroidism in a 3-year-old dog was manifested clinically as periodic episodes of depression, vomiting, and tetanic convulsions. Hypocalcemia and hyperphosphatemia were detected late in the course of the illness, but the dog died before corrective measures could be instituted. The pathologic features were similar to those reported in dogs in which hypoparathyroidism was induced by injection of homologous parathyroid tissue, thus suggesting an auto-immune pathogenesis.

A 5-week-old mixed-breed dog was examined because of emaciation and depression associated with chronic anorexia, diarrhea, and vomiting. Its rectal temperature was subnormal and it died on the day of admission. At necropsy, small focal lesions were distributed through the liver. Enteric alterations included catarrhal enteritis with fluid contents, excess production of mucus, and mucosal hyperemia. Microscopically, the hepatic lesions were disseminated foci of coagulative necrosis, with little or no associated inflammatory cell response. Numerous organisms morphologically consistent with Bacillus piliformis were demonstrated within viable hepatocytes at the periphery of the necrotic foci and in the intestinal mucosa. Numerous coccidial forms were found within the epithelial cells of the intestinal mucosa, which was focally necrotic.

In the last twenty years maternal mortality attributed to anaesthesia has decreased. Inhalation of gastric contents is the commonest cause in patients undergoing cesarean section; in fact pregnant women are considered "high risk" because of gravidic modifications. In this retrospective study of 10017 caesarean sections performed under general anaesthesia in our institution between January 1980 and December 1990, we evaluated the frequency of this syndrome (7 cases = 1:1431). We had no case of maternal and neonatal mortality. All these seven patients were admitted at our recovery room for less than 5 days; aspiration pneumonitis occurred in only three patients. Our results suggested that induction of anaesthesia with high doses of thiopental reduces complications related to light anaesthesia, including vomiting. At a dose of 5-6 mg/kg thiopental didn't produce any significant neonatal depression as documented by Apgar scores.

The radiolabelled opioid receptor binding affinities of morphine and its active metabolite morphine 6-glucuronide at the total mu, mu 1, mu 2 and delta receptors were determined. Morphine 6-glucuronide was found to have a 4-fold lower affinity for the mu 2 receptor (IC50 17 nM and 82 nM for morphine and morphine 6-glucuronide respectively, P = 0.01), the receptor postulated to be responsible for mediating the respiratory depression and gastrointestinal effects after morphine. This provides a possible explanation for the reduced respiratory depression and vomiting seen following morphine 6-glucuronide in man. A similar reduction in affinity of morphine 6-glucuronide was seen at the total mu receptor whilst there was no significant difference seen at the mu 1 or delta receptor. Hence the increased analgesic potency of morphine 6-glucuronide over morphine remains unexplained.

The safety and efficacy of patient-controlled analgesia used for postoperative pain relief were evaluated. Cumulative 24-hour requirements were analyzed for possible correlation with patient characteristics. All patients who used a patient-controlled analgesia device for postoperative pain relief were reviewed from June to October 1991. The device Baxter's basal/bolus infusor with patient control module, was used to deliver fentanyl in 379 patients. The fentanyl requirement, verbal analog pain score, first passage of flatus, side effects, sedative score, and degree of satisfaction were examined. The fentanyl requirement during the first 24 hours after operation was analyzed with regard to age, body weight, and sex. The daily fentanyl consumption in the first three postoperative days was 928 +/- 352 micrograms (n = 338), 553 +/- 259 micrograms (n = 220), and 490 +/- 222 micrograms (n = 71), respectively. The requirement for fentanyl during the first 24 hours after surgery was significantly higher than for the next two days (p-value < 0.001). Fentanyl consumption correlated well with body weight, and inversely with age. No difference was found between fentanyl consumption and sex (p-value = 0.4687). The mean time to the first passage of flatus in patients with abdominal surgery was 54.6 +/- 26.4 hours. The incidence of nausea, vomiting, and dizziness was similar, about 20% of patients. Itching was noted in 7% of patients. Oversedation (class 4) was found in three patients during the first operative day, the sedative score for other patients were around class 1-3. No patient exhibited signs of respiratory depression or withdrawal syndrome.(ABSTRACT TRUNCATED AT 250 WORDS)

The clinical features and management of nine cases of mushroom poisoning due to Amanita pantherina (eight cases) and Amanita muscaria (one case) admitted to a children's hospital are described. Most ingestions were in the toddler age group with males being more frequently involved. Symptoms occurred between 30-180 min with the onset of central nervous system depression, ataxia, waxing and waning obtundation, hallucinations, intermittent hysteria or hyperkinetic behavior. Vomiting was rare. Seizures or myoclonic twitching occurred in 4/9 patients, but was controlled with standard anticonvulsant therapy. No other anticholinergic or cholinergic signs were prominent. Recovery was rapid and complete in all patients.

A review of the safety and tolerability of fluvoxamine in worldwide marketing studies involving 24,624 patients, predominantly receiving fluvoxamine treatment in uncontrolled studies in depression, has been conducted. There was a marked preponderance of female patients and patients aged between 30 and 50 years. The majority of patients were treated for 6 weeks, with the most frequent modal total daily dose being 100mg. The greatest proportion of adverse experiences occurring, by COSTART body system, affected the digestive system (24.1%), the nervous system (23.7%), and the body as a whole (15.3%). The only adverse experience with an incidence greater than 10% was nausea (15.7%), with somnolence (6.9%) and asthenia (6.2%) as the next most frequent experiences. Notably, the rates of agitation and anxiety were only 1.4 and 1.3%, respectively. The incidences of adverse experiences increased with age, and were slightly higher in females than males. 15.1% of patients discontinued treatment prematurely as a result of adverse experiences, principally nausea, dizziness, vomiting, somnolence, abdominal pain, and headache. The overall incidence of serious adverse events associated with fluvoxamine treatment was 2.5%, and the incidence of overall suicidality, including suicidal ideation, overdose, and intentional overdose as well as attempted and completed acts of suicide, was remarkably low at 0.8%.

Ondansetron (GR 38032) has potent and highly selective antagonist properties at the 5-hydroxytryptamine (5-HT, serotonin) 5-HT3 receptor. The selectivity ratio for ondansetron on 5-HT3 receptors compared with actions on other neurotransmitter receptor types is greater than 1,000. The antiemetic properties of ondansetron have been determined in ferrets against the nausea and vomiting induced by cisplatin, cyclophosphamide, and whole-body radiation. Ondansetron (intravenous 0.01 to 0.1 mg/kg or subcutaneous 0.1 to 0.5 mg/kg) or metoclopramide (1.0 to 4.0 mg/kg) cause dose-dependent inhibitions of the vomiting induced by each of these procedures. Unlike ondansetron, the effects of metoclopramide are accompanied by moderate to marked behavioral depression. Since metoclopramide is 50 times more potent on dopamine D2 receptors than on 5-HT3 receptors, the behavioral depression is likely due to profound blockade of dopamine receptors. The 5-HT3 receptors have been shown to be present peripherally on vagal afferent fibers and are densely located in the vomiting center of the hindbrain. The current hypothesis is that there may be both a peripheral and a central site of action for ondansetron and other 5-HT3 antagonists. The lack of antagonist activity on dopamine and other non-5-HT3 receptors indicates that, unlike metoclopramide, ondansetron will not cause extrapyramidal or other dose-limiting side effects.

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)
