OBJECTIVES: As one of the possible mechanisms of viral evasion in the HPV-infected cervical cancer cells, the role of amino acid sequence change in epitope region has not been reported yet. In this study, sequence variations of HPV 16 E6, E7 gene, especially focused on epitope region, were analysed, the status of immunomodulatory factors were documented, and finally the possible correlation between the sequence variations and the loss of HLA class I expression was examined. METHODS: The entire ORF(open reading frame)s of HPV 16 E6, E7 were sequenced by the fluorescent dideoxy termination method. In addition proteins and transcripts of HLA-ABC, beta2-microglobulin(beta2-m), TAP (transporter associated with antigen processing), and LMP(large multi-functional proteasome) were evaluated by immunohistochemistry and RT-PCR, respectively in 40 clinical specimens of primary cervical cancer and 6 cervical cancer cell-lines. Medical records including pathologic reports were reviewed. RESULTS: Among the 27 cases confirmed as harboring HPV 16 DNA, only one(3.7%) found as a prototype. Among 11 kind of variants identified in total, 4 variants(5 nucleotide sites) which were never reported before has been found, registered firstly to GenBank. The most frequently found one(16 cases, 59.3%) contains D25E, N29S in E6, E7 region, respectively and the most common variation in E6, E7 ORFs found concurrently(p<0.05). Down-regulation of HLA-ABC and beta2-m was identified in 32(86.5%) and 35 cases(89.7%), respectively and transcripts of TAP, LMP were identified in over 85% of cases. However, there was no significant difference in HPV 16 infection, D25E in E6 and so on between HLA-ABC, beta2-m positive and negative groups. The well-known clinicopathologic parameters did not correlate with sequence variations and immunomodulatory factors. Five sequence variations in HPV 16 E6, E7 ORFs that were not previously reported worldwide were found, registered firstly to GenBank. CONCLUSION: It seems that multiple mechanisms are operated in down-regulation of HLA class I molecules and the phenotypic profile of immunomodulatory factors seems to be unrelated in vivo to the naturally occurring HPV 16 E6, E7 variations in epitope region.

PURPOSE: Pilomatrixoma is a benign, usually asymptomatic tumor. It presents clinically as a solitary superficial subcutaneous nodule measuring between 0.5 cm and 5 cm in diameter on the head or upper extremeties and has not been reported after skin graft. The objective of this article is to report our experience in treating pilomatrixoma which occurred after split thickness skin graft on the lower extremity. METHODS: A 56-year-old female was treated in August 2005 with a 0.5 X 0.5 cm firm subcutaneous nodule at recipient site of split thickness skin graft on the left medial thigh. The tumor was successfully removed by complete excision and histologic examination was followed. RESULTS: The diagnosis was pilomatrixoma which was characterized by a dual population of proliferating basophilic cells and diagnostic shadow cells. CONCLUSION: The tumor was successfully treated by complete resection. The authors report this very rare case of pilomatrixoma which occurred at recipient site of split thickness skin graft.

In determining the effects of strabismus surgery, it is very important to know where the reattachment site of an extraocular muscle following recession procedure is located. Undercorrections or overcorrections after muscle surgery have been thought to be due to a postoperative positional changes of reattachment site along the surface of the globe. The author performed this experimental study to evaluate the amounts of changes of reattachment site after recession procedure in rabbit with 4 different methods of scleral fixation;direct suture with 6-0 vicryl, hang-back suture, application with Tisseel and Histoacryl. Superior rectus recession was performed in all 40 rabbit eyes, 10 eyes in each group. The distance from limbus to proximal end of recessed superior rectus muscle was measured on day 1, 2, 3, 5 and 7 postoperatively. Further measurements were followed at 2, 3, 4 and 8 weeks after recession procedure. The muscles were found an average of 0.4mm posterior to the intended position in direct suture group and 0.5 mmin hang-back suture group at one week postoperatively. But in the other two groups in which tissue adhesive agents, Tisseel and Histoacryl were used, the amount of displacement of the reattachment site were minimal of within 0.1 mm. From this experimental study, it is suggested that the positional changes of the reattachment site after recession procedure may influence the surgical corrective effects for strabismus.

BACKGROUND: This is a retrospective, descriptive study, evaluating the observed agreement between 1996 & 2002 Centers for Disease Control and Prevention (CDC) definitions of nosocomial pneumonia (NP) for medical intensive care unit (MICU) and surgical intensive care unit (SICU) patients. METHODS: A total of 476 adult patients who were over 15 years of age and had been admitted to the MICU & SICU of a university hospital between August 1, 2005 and August 1, 2007 were enrolled. Data were collected from electronic medical records according to the 1996 & 2002 CDC definitions of NP. RESULTS: According to the 1996 CDC definitions of NP, there were a total of 116 NP cases and incidence rate was 11.6 per 1,000 patient-days; when analyzed with the 2002 CDC definitions of NP, 75 cases met the criteria and the incidence rate was 7.5 per 1,000 patient-days. Kappa value measuring agreement between the two definitions was 0.67 (95% confidence interval 0.601-0.706). When 1996 CDC definitions were compared with 2002 CDC definitions, sensitivity, specificity, positive predictive value, and negative predictive value were 93.3, 88.5, 60.3, and 98.6%, respectively. CONCLUSION: Even though the aforementioned NP criteria had been applied to the same study population, the number of patients that met the definitions changed depending on which criteria had been used. Therefore, it is necessary to consider the differences when making a comparison.

An unusual case of intraspinal peripheral neuroepithelioma arising from the cauda equina is reported. The patient, a 21-year old female, suffered from low back pain with radiation to the posterior aspect of both legs. Myelographic, computed tomographic scan and magnetic resonance imaging studies of lumbosacral spine showed the intradural extramedullary mass lesion on the L3-S1 level which was excised surgically, but recurred rapidly. It could be diagnosed by the histopathologic findings. The postoperative radiotherapy and chemotherapy were administered. We report this rare case with review of the literatures.
