Aesthetic reconstruction of burn alopecia by using expanded hair-bearing scalp flaps.
Tissue expansion is one of the most important armamentaria for aesthetic scalp reconstruction after burn; however, the proper way to employ this technique for the scalp reconstruction usually presents a challenge to the plastic surgeon, especially in the case of a "sideburn" scenario or a large lesion, as with, for example, hemiscalp alopecia. In this article, 11 patients, with different degrees of hair-bearing scalp loss as a result of burn, and including four patients with hemiscalp alopecia were successfully treated by using tissue expansion. The results show that tissue expansion is a simple, safe, and efficient technique for aesthetic scalp reconstruction. Versatile design of the expanded scalp flap can distribute the expanded hair-bearing scalp properly in the reconstructed recipient site.

Meta AnalysisThe association of placenta previa with history of cesarean delivery and abortion: a metaanalysis.
Our purpose was to determine the incidence of placenta previa based on the available epidemiologic evidence and to quantify the risk of placenta previa based on the presence and number of cesarean deliveries and a history of spontaneous and induced abortion. ⋯ There is a strong association between having a previous cesarean delivery, spontaneous or induced abortion, and the subsequent development of placenta previa. The risk increases with number of prior cesarean deliveries. Pregnant women with a history of cesarean delivery or abortion must be regarded as high risk for placenta previa and must be monitored carefully. This study provides yet another reason for reducing the rate of primary cesarean delivery and for advocating vaginal birth for women with prior cesarean delivery.

Management of the critically ill patient forms a significant proportion of obstetric and gynaecological (O & G) practice. There have however, been very few reports on the management of such patients in intensive care units (ICU). We review all O & G patients admitted to the surgical ICU at King Edward VIII Hospital, Durban, South Africa, and make recommendations regarding management of such patients. ⋯ O & G patients form a major workload of surgical ICUs and the majority of these patients are women with eclampsia. Management of such patients requires an understanding of the physiological changes of normal and abnormal pregnancies. Therefore, all large obstetrical units in developing countries should establish their own ICU in order that patient care, health personnel training and continuing health care education may be improved.

Preoperative assessment of the elderly patient for surgery is vital to the success of the surgical procedure. A thorough evaluation must first begin with an understanding of the physiologic and pathophysiologic changes unique to the elderly patient and the aging skin. ⋯ With the continued growth of the geriatric population, all dermatologic surgeons should be aware of the special issues related to their geriatric patients. With heightened awareness of and screening for potential pitfalls in the elderly surgical patient, adverse outcomes can be avoided.

Postoperative nausea and vomiting remains an important problem. Many risk factors have been identified; however, the importance of postoperative analgesic technique and patient expectation remain poorly defined. ⋯ Study results show that patient expectation is a potent predictor of postoperative nausea, a risk factor hitherto ignored in the anaesthetic literature, and that, in the provision of analgesia following major surgery, epidural analgesia is associated with less PONV than intravenous morphine.
