It has been shown that dimethpramide, a new Soviet-made antiemetic belonging to the group of substituted benzamides, effectively prevents the emetic action of L-DOPA and apomorphine in dogs (the ED50 is 0.04 and 0.12 mg/kg, respectively). When given in doses of 10-25 mg/kg dimethpramide suppresses vomiting induced by adrenaline, histamine, strophanthine, sodium salicylate, and copper sulfate. The drug exerts a selective dopamine-blocking action on the receptors of the triggering zone of the vomiting center without producing any substantial action on the dopaminergic brain systems that regulate behavioral activity.

Thirty-three patients were randomized prior to pelvic radiotherapy to receive the bile acid-sequestering resin colestipol hydrochloride, 5 grams qid, during the entire time of their therapy or diphenoxylate hydrochloride and atropine sulfate 2.5-20 mg per day (control) if they experienced diarrhea. The colestipol patients also took diphenoxylate if they had diarrhea. The patients in the colestipol group often experienced nausea, vomiting, and abdominal cramps and 8 were forced to discontinue the drug. There was no difference in the weekly stool frequency between the colestipol and the control patients but the colestipol patients who took at least 50% of the prescribed dose required fewer diphenoxylate tablets than the controls. The data suggest that colestipol hydrochloride is not of value in preventing radiation-induced diarrhea because of the side effects associated with the drug, but the theory on which the use of bile acid-sequestering agents is based may be correct.

Recently, it has been reported that paromomycin sulfate has marked anthelmintic efficacy against tapeworm infections in man. In the present study this drug was used in the treatment of 14 cases of diphyllobothriasis latum and 1 case of taeniasis saginata. Also, the actions of paromomycin sulfate on Diphyllobothrium ditremum and D. erinacei were examined pharmacologically using Magnus apparatus and biochemical methods. The results obtained were as follows. For the treatment, a total of 50 mg/kg of paromomycin sulfate divided into 2 doses was given orally at intervals of 30 minutes. Two hours after medication, 20 g of magnesium sulfate dissolved in 200--300 ml of water was given as purgative. One or 2 worms were found in the stools of 11 cases with D. latum and 1 case with T. saginata within 24 hours after medication, but scolex was found in only 2 of them. All cases were negative for the eggs or segments in stool examinations at 1 and 3 months after treatment. Except 1 case complained mild and transient vomiting no side effects were noticed. All cases showed no abnormality in blood examination, liver function test and urinalysis. Both of the proglottids of D. ditremum and D. erinacei showed muscle relaxation in Tyrode solution containing 10(-4) g/ml of paromomycin sulfate. In D. ditremum the recovery of muscle tonus was observed within 10--15 minutes after affection of this drug, while the persistence of muscle relaxation was seen in D. erinacei. The activity of phosphoglucose isomerase was slightly inhibited by 10(-3) M paromomycin sulfate while those of hexokinase, phosphofructokinase and glucose-6-phosphate dehydrogenase were not inhibited. In phosphoenolpyruvate-succinate pathway, the activity of fumarate reductase was slightly inhibited 10(-3) M paromomycin sulfate while those of phosphoenolpyruvate carboxykinase and malate dehydrogenase were not inhibited.

Dural sinus thrombosis developed in two children with acute lymphoblastic leukemia during induction treatment with vincristine sulfate, prednisone, and asparaginase. Headache, nausea, emesis, and lethargy were the presenting signs. The diagnosis was confirmed by arteriography. The cause is presumed to be secondary to hypercoagulability due to asparaginase-induced antithrombin III deficiency. The patients received anticoagulation therapy and recovered completely. Only two of the six reported patients without heparinization survived.

We observed serious adverse reactions after premedication for computed tomographic (CT) head scans and therefore determined rates and risk factors for such reactions among 106 hospitalized children monitored by an intensive drug surveillance program. Reactions occurred in 13 patients (13%), including four cases of life-threatening cardiorespiratory depression or arrest after narcotic premedication. Other reactions included CNS depression, behavior changes, voiding problems, and vomiting. The risk of reaction was elevated in subjects who received high doses of a premedication drug (relative risk, 5.2) and in those who received four or more premedication (relative risk, 3.7). All life-threatening reactions occurred among infants younger than 3 months, and two of these followed medication with only morphine sulfate, in the recommended dose. Risks of adverse reactions from premedication should be considered by physicians who order CT scans for hospitalized children.

Ten healthy males between 18 and 33 years received 10 mg morphine sulfate intravenously, or by lumbar epidural injection at two sessions 2-4 weeks apart, in random sequence. The following observations were made at intervals for 22 h. (1) Segmental hypalgesia to ice and pin scratch. (2) Cold pressor response test in hand and foot as an index of analgesia. (3) Time of onset and duration of side effects. (4) Serum concentrations of morphine. Few non-respiratory changes were seen after intravenous morphine. Cold pressor response was unchanged in hand and foot, no segmental hypalgesia or itching occurred, and only one subject complained of nausea. Marked changes occurred after epidural morphine. Cutaneous hypalgesia to ice and pin scratch appeared in the thoracolumbar region all subjects. In six subjects hypalgesia rose to the midthoracic region during the second or third hour and to the trigeminal distribution between the sixth and ninth hour in five subjects. Cold pressor response fell rapidly in the foot during the first 1.5 h after epidural morphine, and a little later cold pressor response also fell in the hand in all subjects, and remained depressed for the duration of the experimental period. Pruritus occurred at three hours in nine of the 10 subjects, nausea at about four hours in six of the subjects, and vomiting at about six hours in five of the subjects. Hypalgesia and side effects were not related to serum concentrations of morphine. These results suggest that lumbar epidural morphine travels cephalad in the cerebrospinal fluid to reach the brain stem and fourth ventricle by the sixth hour.

Ten healthy young male volunteers received in random sequence 10 mg of morphine sulfate intravenously and by lumbar epidural route during two 26-hour study sessions, in order to observe the appearance and resolution of the following side effects: (a) pruritus, (b) nausea, (c) vomiting, (d) urinary dysfunction. With the exception of one subject, who experienced transient (2 hours) nausea, none of the subjects experienced any adverse side effects after the intravenous morphine. However, all subjects experienced some degree of one or more complications, starting 3 hours after the epidural administration: generalized pruritus started at 3.0 +/- 0.3 hours (nine of 10 subjects, mean +/- SD) and lasted 5.3 +/- 4.0 hours. Nausea occurred in six subjects at 4.0 +/- 0.6 hours, and lasted 3.0 +/- 2.1 hours; vomiting occurred at 6.3 +/- 2.0 hours in five of the nauseated subjects. Urinary retention of varying intensity and duration appeared in nine subjects and required pharmacologic intervention in six subjects. Serum levels of unmodified morphine were measured at various times after administration during both sessions and did not correlate with the incidence or temporal appearance of side effects. Serial evaluation of dermatomal level of hypalgesia to ice and pin scratch demonstrated a progressive spread in the rostral direction after epidural morphine; trigeminal areas were affected by 9 hours in five of the 10 subjects. The stereotyped sequence of side effects after 10 mg of morphine by the epidural route can be interpreted to reflect widespread dispersion of morphine throughout the subarachnoid and ventricular cerebrospinal fluid.

Clinical signs and lesions of levamisole toxicosis include: nausea, vomiting, increased salivation, frequent urination and defecation, colic, dizziness, headache, muscle tremors, ataxia, anxiety, hyperesthesia with irritability, clonic convulsions, depression, rapid respiration, dyspnea, prostration, collapse, hemorrhages in the subepicardium and thalamus, enteritis, hepatic degeneration and necrosis, and splenic congestion. Most of these signs and lesions are similar to those observed in nicotine poisoning. Levamisole causes vasopressor and panting effects which are blocked by ganglionic blocking agents hexamethonium and mecamylamine but are not blocked by atropine. The vasopressor effect of levamisole is blocked by alpha-adrenergic antagonists phentolamine and dibenamine; however, the respiratory effect of levamisole is not affected by these alpha-adrenergic antagonists. Repeated IV injections of levamisole cause a tachyphylactic response. With levamisole-induced tachyphylaxis, the effects of other ganglionic stimulants dimethylpiperazinium and nicotine are also abolished. Levamisole causes an electroencephalographic arousal which is antagonized by atropine sulfate and mecamylamine. There is also a structural similarity of levamisole to nicotine. These studies suggest that levamisole is a nicotine-like compound. Possible treatment of levamisole poisoning is discussed. Drug interactions of levamisole with organophosphates and anthelmintics, eg, pyrantel, methyridine, and diethylcarbamazine, are also discussed.

Intravenous injection of crude marijuana extract led to development of an acute illness with multisystem involvement. Gastrointestinal manifestations consisted of severe vomiting, diarrhea, and crampy abdominal pain. Hypotension, tachycardia, and peripheral vasodilation constituted the main cardiovascular manifestations of the disease. Moderate azotemia and oliguria, presumed to be of prerenal origin, were present and rapidly resolved with administration of intravenous fluids. Hematologic manifestations consisted of leukocytosis with a left shift, thrombocytopenia, prolonged partial thromboplastin time, increased fibrin degradation products, and positive protamine sulfate test. The observed coagulation abnormalities may suggest intravascular coagulation. C3, C4, and total hemolytic complement were reduced, suggesting possible activation of the complement system. Hyperventilation, hypoxemia, pulmonary edema, obstructive, and restrictive pulmonary function abnormalities and bilateral pleural effusions highlighted the pulmonary manifestations of the disease. Rhadbomyolysis and mild hepatic function abnormalities were also present. All observed abnormalities reversed in a few days with no significant sequelae.

An osmotic laxative containing polyethylene glycol and sodium sulfate (Golytely Braintree Laboratories, Inc., Braintree, MA) is widely used to clean the colon for colonoscopy. However, its salty taste makes the mixture unpalatable. We therefore tested the claim that a similar solution but without sodium sulfate (Golytely-RSS Braintree Laboratories, Inc., Braintree, MA) makes preparation of the colon more acceptable to patients in a double-blinded randomized controlled trial. Colonic preparation using polyethylene glycol with or without sodium sulfate was randomized in 100 patients due to undergo colonoscopy. The overall acceptability of the regimen was measured on a linear analogue scale and an estimate of symptoms was obtained. Body weight and serum electrolytes, urea, creatinine, hemoglobin and hematocrit were determined before and after preparation in order to assess fluid absorption. The efficacy of colonic cleansing was graded by the colonoscopist. Four patients did not complete the protocol, 47 received the regimen containing sodium sulfate and 49 received the regimen without it. The two groups did not differ in age or body mass. There was no statistical difference in the overall acceptability of the two regimens to the patients (median acceptability rating 74 for regimen with sodium sulfate, range 4-100 compared with 77 for regimen without, range 3-100, p = 0.32, Mann-Whitney test). Nor was there any difference in taste, nausea, vomiting, cramping or perianal discomfort or in the endoscopists' rating of the cleanliness of the colon. The serum sodium concentration rose slightly (mean 1.6 mmol/L) when the regimen with sodium sulfate was used.(ABSTRACT TRUNCATED AT 250 WORDS)
