RESUMO
In a study of injection safety in Abha health district, Saudi Arabia, data were collected from 47 physicians and 85 nurses at 24 primary health care centres, using an observation checklist and an interview questionnaire. All centres used individually packed disposable syringes and puncture-proof containers to collect used needles. Needlestick injury in the previous year was reported by 14.9% of physicians and 16.5% of nurses (0.21 and 0.38 injuries/person/year respectively). Logistic regression analysis identified recapping the needle after use (physicians and nurses) and bending the needle before disposal (physicians) as significant risk factors for injury.

To study emergency services delivery in all 30 primary health care centres in Abha district of Asir region, Saudi Arabia, data were collected about equipment and facilities, physicians' practices and attitudes, and patients' utilization of and satisfaction with emergency services. Two centres had no devoted place for emergency services. Lack of some essential equipment and drugs was evident. The greatest continuing medical education need for doctors was the management of cardiovascular emergencies (72.3%). Many doctors (40.4%) did not consider the majority of cases as true emergencies. Many patients (43.7%) used the centres for emergency services, the most common being trauma, burns and orthopaedics (47.8%). Most patients were satisfied overall with emergency services (82.2%).

This epithelium in developing first and second molars of 1-15 days old balb/c mice was examined by light and electron microscopy. The lysosomal content of these epithelial cells was assessed using CMPase as a marker. At the early developmental stages (4-7 days), the epithelial cells at the enamel-free areas had morphological features of secretory cells. A distinct afibrillar layer was identified covering the enamel-free dentine surfaces. This layer was morphologically different from both the underlying dentine and the enamel at its periphery. At a later stage (9 days), the epithelial cells had extensive infoldings of their distal membranes. Also, the secretory organelles were markedly reduced and mostly replaced by abundant mitochondria concentrated in the distal cytoplasm. Numerous CMPase-reactive lysosomal structures were demonstrated in the 9- and 11-day-old specimens. These cytochemical and morphological features are consistent with a resorptive activity for the enamel-free cells during this developmental stage (9-11 days). Subsequently, at 15 days, these cells had regressed into a flattened squamous epithelium that remained in contact with the tooth surface until eruption.
