Tetrahydrocannabinol vs. prochlorperazine. The effects of two antiemetics on patients undergoing radiotherapy

The authors tested the effectiveness of orally administered delta-9-tetrahydrocannabinol (THC) as compared to prochlorperazine for the alleviation of symptoms, such as vomiting and nausea, experienced by patients receiving radiotherapy. The test subjects rated the severity of their illness, as well as the extent of their subsequent moods, their level of concentration, their amount of physical activity, and their desire for social interaction. They chose the drug they preferred and recorded its side effects. The use of THC was slightly more beneficial than the use of prochlorperazine.     

Greater trochanteric overgrowth: development and surgical correction

Greater trochanteric advancement (GTA) is an orthopedic procedure designed to correct the biomechanical consequences of overgrowth of the greater trochanter by moving the greater trochanter and its attached muscles laterally and distally. Thirty-one children with trochanteric overgrowth who had secondary pelvic instability (Trendelenburg sign) were studied and underwent a total of 33 GTA procedures. The clinical and radiologic prerequisites for successful surgery are presented. In addition, the radiographic methods of measuring the lateral position of the trochanter, the articulotrochanteric distance, and the amount of trochanteric overgrowth are discussed. Measurements made on preoperative and postoperative radiographs revealed that surgery achieved a mean displacement laterally of 12.1 mm and distally 21 mm. Clinically, there were few complications (two children with mild myositis, one with broken hardware, one with delayed union of trochanter). Pelvic instability had disappeared in the 25 of the 30 patients who could be evaluated.     

A Comparative Study of Laparoscopic with Conventional Open Donor Nephrectomy in Renal Transplantation

Background

Laparoscopic donor nephrectomy (LDN) has been gaining popularity among kidney donors. There have been concerns about the safety and efficacy of the procedure as compared to open donor nephrectomy (ODN). We compare our results on LDN with ODN.

Methods

We retrospectively analysed our data of LDN and ODN. Duration of surgery, blood loss, period of hospitalisation, per oral intake and analgesic requirements.

Result

22 LDNs were done, the operation time ranged from 220-300 minutes, and blood loss from 100-150ml. In the first 10 laparoscopic operations four cases required conversion to open surgical dissection. Only one case was converted to open surgery in the subsequent 12 laparoscopic cases. Oral intake was started on the first postoperative day. Analgesic requirement in laparoscopy cases was less. Patients were mobilised on the first day after surgery. Patients were discharged by seventh day. There was no significant difference in the functioning of the graft after revascularisation in the recipient.

Conclusion

Laparoscopic donor nephrectomy is a safe and effective technique of donor nephrectomy.Key Words: Laparoscopy, Laparoscopic donor nephrectomy, Living kidney donors, Kidney transplantation     

A computer-assisted three-dimensional treatment planning system

The three-dimensional treatment planning system developed at the Rhode Island Hospital visualizes the spatial interrelationships of the radiation beam, the tumor, and the adjacent organs within the patient. It is possible to rotate and vary the scale of the display to better comprehend the extent of these structures. By viewing the display as if from along the radiation beam, one can design shaped treatment fields which best suit the three-dimensional nature of the disease. With this system, it is possible to reduce the volume of normal tissue which would typically be irradiated if two-dimensional treatment planning techniques and assumptions were employed.
