The treatment of donor sites with cultured epithelial grafts

In a significant number of elderly patients, the healing of split skin donor sites can be delayed. The cultured allogenic epithelial graft (CAG) has been reported to heal leg ulcers. The mechanism of action may be to improve the healing environment and thus stimulate the host skin cells. A clinical trial was undertaken to compare the healing rate of the donor sites of elderly patients using CAGs and two commercially available dressings. Compared to Jelonet, CAGs (p = 0.008) and OpSite (p = 0.013) significantly reduced the number of patients with delayed healing. There was no significant difference between CAGs and the occlusive dressing, OpSite.     

The effect of naloxone on the preoperative gastric volume and pH

The effect of 4 mg oral naloxone on preoperative gastric volume and pH of gastric aspirate was studied in a double-blind, randomized study. Twenty patients received 10 ml of naloxone (4 mg) mixed with 10 ml of orange juice, and 20 patients received 10 ml of isotonic saline mixed with 10 ml of orange juice, 2 h before surgery. Gastric content was obtained immediately after intubation of the trachea. No significant difference in gastric volume and pH of gastric aspirate was found between the two groups. It is concluded that naloxone does not affect gastric emptying and gastric acid secretion to a degree great enough to protect against aspiration of gastric contents into the lungs.     

A survey of general surgeons' attitudes towards breast reconstruction after mastectomy.

Within the last 15-20 years there have been many changes in the management of breast cancer. Along with changes in treatment, possibilities for breast reconstruction have become increasingly sophisticated and commonplace. Despite the availability of breast reconstruction, we have noted large variations in referral patterns. Because the surgical treatment of breast cancer is largely undertaken by general surgeons, we investigated general surgeons' attitudes towards reconstruction using a postal questionnaire. In 1995, a questionnaire involving hypothetical criticisms was sent to general surgical members of the Association of Surgeons of Great Britain and Ireland. A total of 136 surgeons responded, 79 (58%) of whom had a specialist interest in breast cancer. Each surgeon saw an average of 68 new cases of breast cancer per year (range 0-400). The general surgeons were concerned about three areas: (1) 32.3% felt that breast reconstruction might adversely delay the detection of local recurrence; (2) 16.6% were worried that breast reconstruction has high morbidity; and (3) 17.4% said that patients did not want breast reconstruction despite being advised of its availability. To investigate these concern's further, an extensive literature search was undertaken. There is no evidence that breast reconstruction delays the detection of local recurrence. With appropriate patient selection, the morbidity of reconstructive options appears very acceptable. Finally, immediate breast reconstruction has psychological benefits when compared with delayed reconstruction.
