Special care dentistry: how prepared are we?

AIM: To assess and evaluate the confidence of the undergraduate dental team in Irish dental schools regarding their training in the field of special care dentistry (SCD). METHOD: A questionnaire was distributed amongst the undergraduate dental teams within Cork University Dental School and Hospital (CUDSH) and Dublin Dental University Hospital (DDUH). The data were analysed to assess for differences between the median responses of the various groups. RESULTS: A total of 139 students participated in the study; 82 from DDUH (59 dental science students, seven dental hygiene students and 16 dental nursing students) and 57 from CUDSH (43 dental science students and 14 dental hygiene students). Twenty-two per cent (n = 30) of respondents agreed that their training had been sufficient in providing treatment or assistance for patients requiring SCD. Seventy-five per cent agreed that more emphasis should be placed on clinical training in SCD (n = 76). Thirty-one per cent of students anticipated a high level of confidence in treating patients requiring SCD upon graduation (n = 43), with dental science students feeling the least prepared amongst the dental team. CONCLUSION: Confidence levels of the undergraduate dental team were low with regard to SCD. The existing hands-on clinical training in SCD was deemed insufficient by the respondents. Students believed more emphasis should be placed on SCD training in the undergraduate curriculum.

Cytochrome P450 3A4 genetic polymorphisms and post-operative fentanyl requirements.

WHAT IS KNOWN AND OBJECTIVE: Interindividual variability in drug responses may be attributable to genetically determined alteration in enzyme activity. In this study, we investigated the association between cytochrome P450 3A4 (CYP3A4) genetic polymorphisms and post-operative fentanyl requirements. METHODS: Patients (n = 94) scheduled for gynaecological laparotomy received i.v. fentanyl infusion (3 µg/kg/h) after induction of general anaesthesia. Post-operative fentanyl requirements were quantified by using a patient-controlled analgesia and the number of i.v. fentanyl rescue analgesia required were recorded. Pain control was assessed using visual analogue scores (VAS) and fentanyl's adverse effects were documented. CYP3A4*4, CYP3A4*5 and CYP3A4*18 alleles of cytochrome P450 3A4 were identified by polymerase chain reaction-restriction fragment length polymorphism. Differences in fentanyl requirements, VAS scores and adverse effects among the various genotypes were compared. RESULTS AND DISCUSSION: No CYP3A4*4 and CYP3A4*5 alleles were detected. Eighty-nine patients (94·7%) were wild-type, five (5·3%) were heterozygous and none was homozygous. No significant difference was demonstrated between the genotype groups in terms of fentanyl consumption, pain control and adverse effects. WHAT IS NEW AND CONCLUSION: CYP3A4*4 and CYP3A4*5 are rare in the Malaysian Malay population. Genetic polymorphism of CYP3A4*18 may not play an important role in influencing postoperative fentanyl requirements.

Acceptability of epidural analgesia for pain relief during labour among Kelantanese women.

Three hundred and five primigravid women were interviewed at term to assess the acceptability of epidural during labour, and reasons for the decisions. Data was collected on a prestructured proforma which consisted of background information, socio-economic status, knowledge about epidural analgesia, source of information and reasons for choice. Of the 305 patients only 17.3% were willing to receive epidural analgesia. This group consisted of 56.6% non-Malay women. Those employed in professional or skilled jobs (56.6%) also readily consented for epidural. Nearly half the women willing for epidural had received college (tertiary) education (43.3%) and more than a quarter (26.4%) were over 30 years of age. The majority of those who were unwilling had no prior knowledge about the procedure, and refused either out of fear, ignorance, resistance from husbands, on religious grounds or following poor feedback from friends. In order to advocate epidural analgesia, knowledge has to be targeted to the relatively less educated, unemployed women, mainly through the media or personally in the antenatal clinic by doctors and nurses. Services have to be improved as substandard analgesia may send out wrong messages and actually do more harm than good.

A new species of insular Rock Gecko (Genus Cnemaspis Strauch, 1887) from the Bidong Archipelago, Terengganu, Peninsular Malaysia.

A new insular species Cnemaspis bidongensis sp. nov. (Squamata: Gekkonidae), is described from Pulau Bidong, Terengganu, Peninsular Malaysia and bears a unique suite of morphological and color pattern characters that differentiate it from all other congeners. Cnemaspis bidongensis sp. nov. is the sister species to C. kendallii (Gray) and represents the fifth insular endemic species of Cnemaspis on archipelagos along the east coast of Peninsular Malaysia. This species survived massive deforestation of the small island of Bidong (260 ha) from the mid 1970s to the early 1990s when the island served as a Vietnamese refugee camp and harbored as many as 40,000 people at one time. We hypothesize that this species' generalized lifestyle contributed to its survival, allowing it to seek refuge in rocky microhabitats.
