Human cytochrome P4502E1 (CYP2E1) is a well-conserved xenobiotic-metabolizing enzyme expressed in liver, kidney, nasal mucosa, brain, lung, and other tissues. CYP2E1 is inducible by ethanol, acetone, and other low-molecular weight substrates and may mediate development of chemically-mediated cancers. CYP2E1 polymorphisms alter the transcriptional activity of the gene. This study was conducted in order to investigate the allele frequency variation in different populations of Andhra Pradesh. Two hundred and twelve subjects belonging to six populations were studied. Genotype and allele frequency were assessed through TaqMan allelic discrimination (rs6413419) and polymerase chain reaction-sequencing (-1295G>C and -1055C>T) after DNA isolation from peripheral leukocytes. The data were compared with other available world populations. The SNP rs6413419 is monomorphic in the present study, -1295G>C and -1055C>T are less polymorphic and followed Hardy-Weinberg equilibrium in all the populations studied. The -1295G>C and -1055C>T frequencies were similar and acted as surrogates in all the populations. Analysis of HapMap populations data revealed no significant LD between these markers in all the populations. Low frequency of $CYP2E1^*c2$ could be useful in the understanding of south Indian population gene composition, alcohol metabolism, and alcoholic liver disease development. However, screening of additional populations and further association studies are necessary. The heterogeneity of Indian population as evidenced by the different distribution of $CYP2E1^*c2$ may help in understanding the population genetic and evolutionary aspects of this gene.

Background: The management of the behavior of handicapped children when providing required dental care is often a problem, whether in the dental office or in a hospital setting. Because of the high incidence of poor cooperation, many of these patients are scheduled for dental care under general anesthesia with preoperative medical assessment. The purpose of this study was to carry out a clinico-statistical survey on dental treatment for handicapped children under general anesthesia. Methods: After approval from the institutional review board, the medical records of 64 handicapped children between 1997 and 2002 were reviewed to determine the patient profiles, anesthesia management, and complications. The charts of these patients, who underwent dental examination, scaling and prophylaxis, and restoration and extraction of teeth under general anesthesia, were reviewed. Results: The mean age was 12.8 years old, and males (53%) predominated females (47%). Twenty-four patients had mental retardation, twelve had autism, six had cerebral palsy, 4 had behavior disorder, others had heart disease, convulsive disorder, etc. Sixty-two had intravenous thiopental with neuromuscular blocker, 2 had intravenous ketamine induction. Nasotracheal intubation was uneventful in 55 patients, nine had orotracheal intubation because of difficult visualization of the larynx. Twenty-one patients experienced postoperative complications in the recovery room, including epistaxis, nasal obstruction, vomiting, airway obstruction, respiratory depression. Conclusions: General anesthesia is a very effective way of completing the dental treatments for disabled children. We emphasize the need to train anesthesiologists in the care of disabled patients.

점막형 악성흑색종 10례에 대한 임상분석 결과 비강에서 가장 호발하였고 증상은 비폐색이 가장 많았다. 치료 성적은 수술을 우선적으로 선택한 후 방사선요법을 시행한 경우군에서 평균생존기간이 20.8개월이었고 방사선치료를 우선적으로 선택한 경우군에서는 14.7개월로, 접막형 악성흑색종의 경우 광범위 절제술 후 방사선요법을 시행하는 것이 도움이 될 것으로 생각되나 윈격전이 6례를 포함한 8례의 환자에서 재발이 있어 예후가 극히 불량한 암종으로 생각된다.

Chondrosarcoma of the head and neck is very rare tumor and this incidence was reported to be about 10% of all chondrosarcomas. Maxilla is the most common site of involvement and mandible, paransal sinus, nasal cavity and base of skull in that order. In general, chondrosarcoma has been known to be radioresistant, however since the Princess Margaret Hospital reported that it was radioresponsive tumor in 1980, the role of radiotherapy has been emphasized in terms of local control, especially in head and neck regions where complete excion is often difficult to achieve. The authors experienced 4 cases of chondrosarcoma of head and neck among all 29 chondrosarcoma patients from 1971 to 1985. The clinical and pathologic feature of this disease, it's treatment and prognosis were reviewed along with the literatures.

Objective: The purpose of this study was to evaluate differences in three-dimensional (3D) morphology of the hard palate between Korean adults with and without mild-to-moderate obstructive sleep apnea (OSA) using cone-beam computed tomographic (CBCT) data. Methods: The protocol for the two-dimensional (2D) and 3D mathematical modeling was established by analyzing CBCT images of 30 adults with OSA and 30 matched controls without OSA, using MIMICS software. The linear and angular measurements were also determined using this software. The measurements were repeated for 30 palates, by the same operator, to assess reliability. Results: The palates of OSA patients were higher in the posterior part and narrower in the anterior-superior part than those of the control group (p < 0.05). The nasal cavities of patients with OSA were narrower (p < 0.05) than those of controls. The increasing angle of the first molar palatal root is a compensation of the upper dental arch to improve occlusion. However, for most palatal measurements, there were no significant differences between the OSA and control groups (p > 0.05). The results of 2D and 3D mathematical models were consistent for linear and angular measurements, indicating that 2D and 3D mathematical modeling of the palate is a reliable methodology. Conclusions: OSA is a multifactorial disease; the palates of adults with mild-to-moderate OSA do not have specific morphological features distinct from those of healthy controls.
