Background: The purpose of this study was to compare the availability of propofol and fentanyl (P + F) with diazepam and morphine (D + M) for intravenous conscious sedation during third molar surgery. Methods: Forty patients without systemic disease were operated under IV conscious sedation administered by either of the two techniques. Monitoring consisted of continuous observation of pulse rate, blood pressure, oxygen saturation, and the respiratory rate and were recorded every 15 minutes. Cooperation score was measured 5 and 15 minutes after induction of IV sedation. Following the operation, the surgeon and patients completed questionnaires including pain visual analog scale, amnesia, and side effects. Results: The P + F group was significantly more cooperative than the D + M group. The side effects of D + M group included pain on injection, nausea/vomiting and abdominal pain. The side effects of P + F group included talkativeness, nausea/vomiting, temporary apnea, pain on injection and vertigo. Conclusions: In this study, there were following benefits in the P + F group; more cooperative status and less pain perception. But respiratory depression developed in some patients.

The bilateral cleft lip, a more severe form of clefting than unilateral cleft lip, involves separation of the lip along philtral lines, isolating the central segment (prolabium). Bilateral cleft lip may be either symmetrical or asymmetrical, in which case the cleft lip is split more on one side than on the other. The cleft affects the obvious facial form as an anatomic deformity and has functional consequences, affecting the child's ability to eat, speak, hear, and breathe. Although there would seem to be quite a variance in reported figures, ratios of cleft lip with or without cleft palate have gone as high as 1:500 and as low as 1:1000. It is known that less than 10% of cleft lips are bilateral. Although bilateral cleft lip is less common than unilateral cleft lip, the deformity is more severe, and the reconstructive technique is more complex. Surgery is the only treatment necessary for patients with bilateral cleft lip. Accompanying the evolution of surgical repair is the increasingly important role of orthodontic support with early presurgical alveolar and nasal molding. Repositioning the maxillary and alveolar segments into a more anatomic position allows the surgeon to repair the lip and associated nasal deformity under more optimal conditions. The purpose of this article is to review the related anatomy, presurgical management, and surgical management of bilateral cleft lip.

Background: The authors studied the hemodynamic effect influent by using the novel high concentration of lidocaine HCl for surgical removal impacted lower third molar. The objective of this study was to evaluate the hemodynamic change when using different concentrations of lidocaine in impacted lower third molar surgery. Methods: Split mouth single blind study comprising 31 healthy patients with a mean age of 23 years (range 19-33 years). Subjects had symmetrically impacted lower third molars as observed on panoramic radiograph. Each participant required 2 surgical interventions by the same surgeon with a 3-week washout period washout period. The participants were alternately assigned one of two types of local anesthetic (left or right) for the first surgery, then the other type of anesthetic for the second surgery. One solution was 4% lidocaine with 1:100,000 epinephrine and the other was 2% lidocaine with 1:100,000 epinephrine. A standard IANB with 1.8 ml volume was used. Any requirement for additional anesthetic and patient pain intra-operation was recorded. Post-operatively, patient was instructed to fill in the patient report form for any adverse effect and local anesthetic preference in terms of intra-operative pain. This form was collected at the seven day follow up appointment. Results: In the 4% lidocaine group, the heart rate increased during the first minute post-injection (P < 0.05). However, there was no significant change in arterial blood pressure during the operation. In the 2% lidocaine group, there was a significant increase in arterial blood pressure and heart rate in the first minute following injection for every procedure. When the hemodynamic changes in each group were compared, the 4% lidocaine group had significantly lower arterial blood pressure compared to the 2% lidocaine group following injection. Post-operatively, no adverse effects were observed by the operator and patient in either local anesthetic group. Patients reported less pain intra-operation in the 4% lidocaine group compared with the 2% lidocaine group (P < .05). Conclusions: Our results suggest that a 4% concentration of lidocaine HCl with 1:100,000 epinephrine has better clinical efficacy than 2% lidocaine HCl with 1:100,000 epinephrine when used for surgical extraction of lower third molars. Neither drug had any clinical adverse effects.

Regional cancer epidemiology is an important basis for determining the priorities for cancer control in different countries worldwide. There is no reliable information about the pattern of head and neck cancer in western Nepal and hence an attempt was here made to evaluate the situation based on hospital data, which provide the only source in the western region of Nepal. A clinicopathological analysis of head and neck cancers treated between 2003 and 2006 in Manipal Teaching Hospital affiliated to Manipal College of Medical Sciences, Pokhara, Western Development Region, Nepal was performed. A total of 105 head and neck cancer cases were identified with a male to female ratio of 1.8:1. The median ages of male and female patients were 62 and 64 years, respectively. Ninety-seven (92.4%) of the cancer patients were suffering from carcinoma, three (2.9%) had blastoma, three (2.9%) had sarcoma, and two (1.9%) had lymphoma. The majority (61.9%) of carcinoma cases were squamous cell carcinoma followed by anaplastic carcinoma (7.2%). Of the carcinoma cases, the most common site of primary lesion was larynx (19.6%), followed by the thyroid (14.4%), the tongue and hypopharynx with 10.3% cases each. Comparative analysis among males and females did not reveal any sex difference in type of head and neck cancers. The head and neck cancer pattern revealed by the present study provides valuable leads to cancer epidemiology in western Nepal and useful information for health planning and cancer control, and future research in western Nepal.
