Terminalia chebula is a commonly advocated agent in Ayurveda for improving gastrointestinal motility. Charles Foster rats (150-200 gms of either sex) were divided into four groups as follows--Group 1 (n = 15) normal animals; Group II (n = 6) rats administered metoclopramide (1.35 mg/kg); Group III (n = 8) rats given atropine (0.45 mg/kg). These agents were injected intramuscularly, 30 mins before the experiment. Rats from Group IV (n = 8) were administered Terminalia chebula (100 mg/kg/day for 15 days orally). Metoclopramide and atropine have established prokinetic and antikinetic activities respectively and are therefore included for comparison. All rats were then given a test meal of methyl cellulose (1.5%) mixed with phenol red (50 mg/100 ml) orally and gastric emptying was measured 20 mins later. Gastric emptying of normal rats (Group I) was found to be 51.6 +/- 7.79%. Metoclopramide significantly increased the gastric emptying (76.33 +/- 12.37%; p < 0.01) and atropine inhibited the motility (% gastric emptying being 7.26 +/- 19.76%; p < 0.01). Terminalia chebula was found to increase the percent gastric emptying (86.57 +/- 6.65%; p < 0.01). Thus from this study it appears that Terminalia chebula can serve as an useful alternative to prokinetic drugs available today.

A new tricortical method of screw implantation for anterior cervical interbody plate fixation is described. The screws are placed obliquely such that they engage the anterior cortex of the body and traverse through the cortices adjoining the disc space. By this method the screws not only hold the plate firmly with a tricortical purchase, but by virtue of their course stabilize the two adjoining vertebral bodies by themselves. Sixteen patients were treated by this method. In three of these cases only tricortical screws without the metal plate were used for fixation. The advantages of the technique are discussed.

Intraparotid facial nerve schwannoma are uncommon. Preoperative diagnosis of parotid tumour as schwannoma is difficult when facial nerve function is normal. A rare case of solitary schwannoma involving the upper branch of the facial nerve is described and the literature on the subject is reviewed.

Twenty eight autopsy specimens of Ebstein's anomaly were studied in order to evaluate the morphologic features of the abnormal tricuspid valve. All cases showed marked dilatation of the original tricuspid annulus, a normally positioned anterior leaflet and variable downward displacement of the posterior and septal leaflets. Sixteen cases showed a very large anterior leaflet. All three leaflets showed dysplastic features and a wide range of anatomic abnormalities in the valve and valve apparatus. A thin walled atrialised right ventricle was present in nine cases. Associated cardiac anomalies were seen in 21 cases, the commonest being an atrial septal defect (17 cases).

A middle aged male patient presented with gradual distension of the abdomen. Imaging modalities showed classical features of pseudomyxoma peritoneii which was confirmed by aspiration cytology. Details of the case are described and relevant literature is reviewed.

A case of idiopathic hypereosinophilic syndrome (HES) is presented. The patient had been symptomatic and had documented peripheral blood eosinophilia for 9 years. The patients having only pulmonary involvement, seem to have a good prognosis and hence must be considered as a separate subgroup of HES.

A rare case of an irreducible post-traumatic lateral dislocation of elbow is presented. The mechanism of injury was fall on a flexed elbow with trauma on its medial aspect resulting in pronation of the forearm. At open reduction, the brachialis muscle was in the form of a tight band which prevented reduction. The ulnar nerve was entrapped in the joint.

An unusual complication following a craniotomy is reported. The free bone flap migrated over the adjacent bone four weeks following surgery and needed operative readjustment. The probable causes for such a complication are analysed and discussed.
