The anti-emetic effects of ondansetron and droperidol were evaluated in 134 ASA Grade I and II female patients, scheduled for laparoscopic cholecystectomy and minor gynaecological laparoscopic surgery, who were randomly assigned to receive ondansetron 4 mg or droperidol 75 micrograms kg-1 intravenously immediately after induction of anaesthesia. The patients were assessed 1, 6, 12 and 24 h after surgery for intensity of nausea and number of vomiting episodes. In the case of the patients undergoing laparoscopy, vomiting episodes occurred in a similar proportion in patients treated with ondansetron or droperidol, with the probability of the Type I error of 0.05 and the Type error II of 0.1. Although there was no difference between the two groups in emetic episodes following all laparoscopic procedures and gynaecological laparoscopic surgery, there was a significant difference between these parameters after laparoscopic cholecystectomy. The patients treated with ondansetron experienced a lower intensity of nausea (P = 0.04) after laparoscopic cholecystectomy, less frequent severe nausea (P = 0.02) and episodes of vomiting (P = 0.04) when compared with those in the droperidol group. We conclude, that despite the result the droperidol prophylaxis appears to be an effective alternative to ondansetron in all patients undergoing laparoscopy, the ondansetron prophylaxis is superior to droperidol in patients undergoing laparoscopic cholecystectomy.

SummaryBackgroundIschiofemoral impingement syndrome is characterized by a hip pain associated with abnormalities in quadriceps femoris muscle and ipsilaterally reduced distance between the lesser trochanter and the ischium. Thus far, the congenital variant of this entity has been reported exclusively in women.Case ReportWe report a case of a 22-year old male with painful hips in whom on the basis of the imaging studies the constitutional variant of ischiofemoral impingement was diagnosed.ConclusionsIschiofemoral conflict should be taken into consideration in the differential diagnosis of hip pain, particularly among women, but also in patients with valgus hip deformity and other abnormalities leading to reduction of the space between femoral and ischial bones independent of gender.
