There is a high incidence of primary colonic intussusceptions in infants and children in Africa. The case histories of 37 patients are reviewed. Of the varieties described, the caecocolic intussusception (16 patients) presents as an intestinal upset, often mild, with symptoms of colic and vomiting. In many of these patients there is known to be an intestinal infestation with Ascaris lumbricoides. This often leads to a delay in establishing the correct diagnosis. Colocolic intussusception (13 patients) gives rise to more acute abdominal symptoms. On clinical assessment, signs of intestinal obstruction are found and there is usually an intra-abdominal mass which can be palpated in the left colon. Further confirmatory evidence of intussusception is the finding of occult blood in stools. There is an unusually high incidence of sigmoid intussusceptions in infants (8 patients). The diagnosis of this form of intussusception is often delayed owing to inadequate clinical assessment of prolapsed bowel at the anal orifice. The length of the prolapsed bowel, the curved nature of the prolapse and the possible demonstration of a sulcus between the prolapsed bowel and the anal canal wall, aid in diagnosis.

Piflutixol, 6-fluoro-9-[3-(4-(2-hydroxyethyl)piperidino)propylidene]-2-trifluoromethyl-thioxanthene, has been shown to have pronounced neuroleptic properties. It is a very potent inhibitor of methylphenidate-induced stereotypies in mice, amphetamine and apomorphine-induced stereotypies in rats, apomorphine-induced stereotypies and vomiting in dogs. Furthermore piflutixol causes cataleptic reaction in small doses and inhibits conditioned avoidance reaction in rats. The compound is equally potent orally and parenterally and has a prolonged effect. Piflutixol has up to the present proved to be the most potent inhibitor of dopamine-stimulated adenylate cyclase in rat striatum in vitro. Piflutixol has a stron sedative effect (inhibition of spontaneous motor activity, induction of ptosis and potentiation of barbiturate anaesthesia) and in addition inhibits reticular arousal reaction in very low doses. Thus piflutixol constitutes a unique combination of potent anti-stereotyped activity with potent sedative effects. This means that piflutixol may prove to be a low-dose basic neuroleptic with long duration of action.

Vertical and medial nephroptosis was assessed on 60 consecutive excretory urographic examinations. Ptosis, both vertical and medial, was seen more commonly in females, and vertical ptosis was more frequent than medial ptosis. In our series there was no significant evidence of predominance on the right side. Dietl crisis, nausea, vomiting, hypotension, oliguria, or orthostatic hypertension were not encountered. Nephroptosis was mostly asymptomatic. In those patients with symptoms, lumbar pain was common and could be either aggravated or relieved by change in position. A new sign, paradoxic displacement, is described. This could be of value to the surgeon and radiotherapist in evaluating enlargement of a huge abdominal mass - a difficulat task to assess clinically.

Prolapse of the gastric mucosa into the duodenum must be considered when a round soft tissue mass is seen in the right upper quadrant on scout abdominal film. Gastric prolapse may mimic tumor in the duodenum when the prolapse is large. Examination with barium meal is necessary to exclude prolapse of the gastric mucosa into the duodenum as a cause of epigastric pain and vomiting. Medical treatment is suggested for patients with mild symptoms, but patients with severe symptoms, repeated hemorrhage, anemia, severe intermittent epigastric pain and vomiting due to ball-valve syndrome should have operation.

Three cases of haematemesis associated with alcohol abuse are described. Early fibreoptic endoscopical examination in each showed a focal, well demarcated area of gastric mucosal haemorrhage, close to the oesophagogastric junction. Two patients showed prolapse of the lesion into the lower part of the oesophagus, and the third had coexistent Mallory-Weiss tears. Our observations suggest that forceful vomiting is responsible for this lesion, by causing abrupt retrograde gastrooesophageal prolapse. The prognosis of the lesion appears good.

Butaclamol hydrochloride (AY-23,028) is a member of a new chemical class for which antipsychotic activity in humans has recently been demonstrated. The compound antagonized amphetamine-induced stereotyped behavior in rats, amphetamine toxicity in aggregated mice and apomorphine-induced emesis in dogs. It depressed both discriminated avoidance and continuous lever-pressing behavior in rats and inhibited ambulation and rearing in the open field. At higher doses, AY-23,028 induced catalepsy. Adrenergic blocking activity, measured by the antagonism of epinephrine-induced mortality, was weak. These pharmacological actions are characteristic of neuroleptic drugs. In the dose range where the aforementioned effects were observed AY-23,028 did not antagonize either the tetrabenazine-induced ptosis or the tremorine syndrome and did not cause either hypothermia or ataxia. The potency and onset of action of AY-23,028 were comparable to those of fluphenazine but AY-23,028 was of longer duration. The results are discussed in relation to current concepts of neuroleptic mechanisms.

Acute oral toxicity of (-)-(S)-9-fluoro-2,3-dihydro-3-methyl-10-(4- methyl-1-piperazinyl)-7-oxo-7H-pyrido [1,2,3-de][1,4]benzoxazine-6-carboxylic acid hemihydrate (levofloxacin, DR-3355, CAS 100986-85-4), a new quinolone antibacterial agent, was studied in ddy mice, SD rats and cynomolgus monkeys. LD50 values were 1,881 mg/kg for males and 1,803 mg/kg for females in mice, 1,478 mg/kg for males and 1,507 mg/kg for females in rats and more than 250 mg/kg in females monkeys. Toxic signs included the decrease in locomotor activity, ptosis, tremor, tonic convulsion and respiratory depressed in rodents and soft feces or vomiting in monkeys. At necropsy, no treatment-related changes were observed in any species except for the enlargement of the cecum in rats.

Dysautonomia, or autonomic nervous system dysfunction, was diagnosed in a 1-year-old dog. Clinical signs of disease included diarrhea, vomiting, prolapse of nictitating membranes, and urinary incontinence. Bilateral keratoconjunctivitis sicca, xerostomia, and decreased anal sphincter tone were also observed. On the basis of response to atropine, results of intradermal histamine testing and gastric motility studies, and ocular response to parasympathomimetics and sympathomimetics (direct and indirect acting), autonomic nervous system function was determined to be abnormal. Treatment with metoclopramide hydrochloride and bethanechol chloride resulted in improved attitude, appetite, Schirmer tear test response, and decrease in frequency of vomiting within 24 hours. Bladder function and anal tone improved within 3 weeks.

The potentiation of motor activity caused by ephedrine (Eph) in mice was inhibited by prazosin but not by sulpiride. This potentiation effect caused by apomorphine (Apo) was not inhibited by prazosin. Apo produced stereotyped behavior (including sniffing, licking, and biting) in rodents, but Eph was ineffective except at the toxic dose (400 mg.kg-1 in mice, 200 mg.kg-1 in rats). Apo antagonized haloperidol-induced catalepsy in mice whereas Eph had no such effect. Severe vomiting was evoked by Apo in dogs, but not by Eph even when lethal dose (20 mg.kg-1) was used. Palpebral ptosis induced by prazosin was abolished by intracerebroventricular injection of Eph in mice, but not affected by Apo. The results suggest that the central stimulating action of Eph is mediated by alpha 1-adrenoceptors and not by dopamine receptors.

N-(2,2-Diphenylethyl)adenosine (DPEA) has been identified as a potential antipsychotic agent acting via stimulation of adenosine receptors. The projected human therapeutic dose, based on animal studies, is 2-3 mg/kg. DPEA has been tested for potential toxicity in mice, rats, dogs and monkeys. Following single oral doses, median lethal dose values were approximately 10-fold greater in rats than in mice, although similar clinical signs including reduced activity, prostration, and necrosis of the tail were seen in both species. DPEA was well tolerated at daily doses up to 40 mg/kg in rats for 2 weeks. A no observed effect level (NOEL) was not identified in the dog or monkey studies. Reduced activity, dacryorrhea, ptosis, hypothermia, necrosis of the tail, and death occurred in rats given 120 and 160 mg/kg. Pathologic changes consisted of pancreatitis, gastric erosion/ulceration, lymphocyte depletion of the thymus, and pulmonary congestion and hemorrhage at 80 mg/kg or greater. In dogs, sporadic emesis was noted at 12.5 mg/kg and greater, and significant pathologic changes consisted of coronary arteritis associated with myocardial lesions and lymphocyte depletion at 25 and 50 mg/kg, pancreatic acinar necrosis at 50 mg/kg, and renal tubular degeneration at 12.5 mg/kg and greater. Emesis and depression were noted at 25 and 50 mg/kg in monkeys. Renal tubular dilatation and degeneration at 25 and 50 mg/kg were noted in the monkeys. These studies demonstrated that DPEA produced a range of adverse effects in common laboratory animal species.
