The management of orbital roof fractures.

The nature and aetiology of orbital roof fractures is discussed and a strategy for their successful management outlined with reference to five clinical cases. Early recognition and treatment of these fractures reduces the high incidence of intra-cranial and ocular complications and the importance of a combined approach involving maxillofacial surgeons, neurosurgeons and ophthalmologists is emphasised. A coronal flap together with frontal craniotomy is recommended for surgical access to the orbital roof and overlying dura. When reconstruction is indicated, autogenous bone harvested from the inner table of the calvarium provides an ideal graft material.

The zygomatico-temporal approach to the skull base: a critical review of 11 patients.

The zygomatico-temporal approach to the base of the skull is a relatively new but established surgical technique. The approach involves the removal of the zygomatic bone to provide access to the skull base, middle cranial fossa, parasellar region and interpeduncular cistern with minimal brain retraction. An excellent view of the bifurcation of the basilar artery and suprasellar region is provided. The outcome of 11 patients undergoing this procedure is reported with particular reference to the post-operative morbidity and the cosmetic result.

Breastfeeding multiples.

Although breastfeeding two or more infants requires greater organization and presents a challenge to the family, it may in the long run save time. Fatigue, the greatest deterrent to breastfeeding multiples, is common among all new mothers. It is essential for the nurse to demonstrate all of the potential positions for feeding, to stress adequate nutrition, and to encourage getting help from others so that the mother has time to rest each day. Nurses are in an optimal position for influencing successful breastfeeding for multiple birth parents. The dearth of knowledge about breastfeeding twins or other multiples indicates the need for research in this area.

Effects of proprietary oral rinses containing chlorhexidine, hexetidine and benzydamine on the proliferation of human buccal epithelial cells in culture.

Cell cultures were established from small samples of buccal tissue, using a 3T3 fibroblast feeder-layer technique. After exposure to increasing dilutions of three proprietary oral rinses for 22 h or 2 h, the effects upon cell proliferation were studied by measurement of [3H]-thymidine incorporation into cellular DNA. Cell membrane damage was assessed by measurement of lactate dehydrogenase content. Cultures exposed to hexetidine-containing or chlorhexidine-containing rinses for 22 h at dilutions of 250-fold or lower showed almost complete inhibition of [3H]-thymidine incorporation. Cultures treated with benzydamine-containing rinse at the same dilutions showed no significant inhibition of incorporation. Exposure to the same dilutions of hexetidine- and chlorhexidine-containing rinses for 2 h resulted in 65% and 20% inhibition of incorporation, respectively. Lactate dehydrogenase content decreased to negligible levels after exposure to the rinse containing hexetidine at a 250-fold dilution, but was unaffected by the other two rinses. Thus dividing buccal epithelial cells in vitro may be adversely affected by exposure to certain commercial oral rinses.
