Although squamous cell carcinomas compose the majority of invasive cervical cancers, adenocarcinomas account for 10-20% of cervical cancers. Human papillomavirus (HPV) types 16 and 18 are strongly involved in the development of cervical neoplastic lesions squamous cell type. However, little is known about the association of HPV with adenocarcinoma because of its rarity, The p53 gene acts as a tumor suppressor and has been implicated in controlling cell cycle progression at the Gl-S transition, and absence or mutant of p53 gene is related to tumor progression. The present study was undertaken to identify clinical profiles, to characterize HPV infection status and p53 overexpression in the cervical adenocarcinoma and to investigate the prognostic significance of these findings. Thirty-six paraffin-embedded tumor tissues were obtained and patients clinical records were reviewed from tumor registry. Tissues were analyzed for the detection of HPV 16/1S by multiplex PCR and for the expression of p53 protein by immunohistochemical staining. Eighty-four percent of the cases were positive for HPV 16 and/or 18. HPV 16 positive rate was 36.1%, HPV 18 was 72.2%. The rate of double infection with HPV 16 and 18 was 25.0%. The p53 overexpression was detected in 11.1%. The overall 5 year-survival rate (YSR) was 72.2%. There were no significant difference in survival rate between HPV 18-positive and HPV 18-negative groups. The 5 YSR of the p53-positive group was 25.0% and that of p53-negative group was 78.1% (p=0.174). Inverse relationship between p53 overexpression and HPV DNA positivity was not found. In cervical adenocarcinoma, HPV type 18 was detected as the predo#minant type and may play a role in the carcinogenic process.

Vulva syringomas are rare in reviewing literature. In our case, a 29-year-old had multiple papular lesions involving both sides of the vulva. Microscopically the lesion showed dilated cystic sweat ducts some of which have small comma like tails resembling tadpoles. It is the purpose of this report to present a rare case of syringoma which was limited to the vulva without involvement of other sites.

PURPOSE: The healthy worker effect is an important issue in occupational epidemiology. This study was conducted to propose a new method to test the relation between exposure and mortality in the presence of the healthy worker effect. METHODS: In this study, the healthy worker hire effect was assumed to operate as a confounding variable of health status at the beginning of employment and healthy worker survival effect as a confounding and intermediate variable of employment status. In addition, the proposed method reflects the length bias sampling caused by changing of an employment status. Simulation studies were also carried out to compare the proposed method with Cox's time dependent covariates models . RESULTS: The theoretical development of the healthy worker survival effect is based on the result that an observation with change of an employment status requires that the survival time without intermediate event exceeds the waiting time for the intermediate event. According to our simulation studies, both the proposed method and Cox's time dependent covariates model which includes the change of employment status as time dependent covariates seem to be satisfactory at 5% significance level. However, Cox's time dependent covariates models without or with the change of employment status as time fixed covariate are unsatisfactory. The proposed test is superior in power to tests based on Cox's model. CONCLUSIONS: The healthy worker effect may not be controlled by classical Cox's proportional hazards models. The proposed method performed well in the presence of healthy worker effect in terms of level and power

Lidocaline if frequently administered as a component of an anesthetic : for local or regional nerve blocks, to mitigate the autonomic response to laryngoscopy and tracheal intubation, to suppress the cough reflex, and for antiarrythmic therapy. Diazepam dectease the potential central nervous system (CNS) toxicity of local anesthetic agents but -may modify the sitmulant action of lidocaine in addition to their own cardiovascular depressant. The potential cardiovascular toxicity of local anesthetics may be enhanced by the concomitant administration of diazepam. This study was designed to investigate the effects of lidocaine dose and pretreated diazepam to cardiovascular system and plasma concentration of lidocaine. Lidocaine in 100 mcg/kg/min, 200 mcg/kg/min, and 300 mcg/kg/min was given by sequential infusion to dogs anesthetized with halothane-nitrous oxide (Group I). And in group II, after diazepam pretreatment, lidocaine was infused by same way when lidocaine was administered in 100 mcg/kg/min, the low plasma levels (3.97+/-0.22-4.48+/-0.36 mcg/ml) caused a little reduction in cardiovascular hemodynamics. As administered in 200 mcg/kg/min, 300 mcg/kg/min, the higher plasma levels (7.50+/-0.66-11.83+/-0.59 mcg/ml) reduced mean arterial pressure (MAP), cardiac index (CI), stroke index (SI), left ventricular stroke work index (LVSWI), and right ventricular stroke work index (PVSWI) and incresed pulmonary artery wedge pressure (PAWP), central venous pressure (CVP), systemic vascular resistance index (SVRI), but was assciated with little changes of heart rate (HR), mean pulmonary artery pressure (MPAP), and pulmonary vascular resistance index (PVM). When lidocaine with pretreated diazepam was administered in 100 mcg/kg/min, the low plasma level, the lower level than when only lidocaine administered. reduced MAP, but was not changed other cardiovascular hemodynamics. While lidocaine was infused in 200 mcg/kg/min, 300 mcg/kg/min in dogs pretreated diazepam, the higher plasma level (7.64+/-0.79-13.79+/-0.82 mcg/ml) was maintained and was associated with reduced CI, SI, LVSWI and incresed PAWP, CVP, SVRI but was a little changes of HR, MPAP, PVRI. After CaCl2 administeration, CI, SI, SVRI, LVSWI was recovered but PAWP, UP was rather incresed than recovered. The foregoing results demonstrate that pretreated diazepam imposes no additional burden on cardiovascular system when a infusion of large dose of lidocaine is given to dogs anesthetized with halothanenitrous oxide. But caution may be advised if the addition of lidocaine is indicated in subjects who have impared autonomic nervous system and who are in hypercarbic, hypoxic, or acidotic states.

We present a case of childhood systemic lupus erythematosus(SLE) with renal disease in a 10-year-old girl with multiple, scattered, erythema multiforme-like eruptions on the face, trunk, forearms and lower legs. Serologic abnormalities included hypocomplementemia, high ANA & anti DNA titers, and LE cell test was positive. The histologic finding of the lesion showed leukocytoclastic vasculitis and direct immunofluorescent test revealed linear deposit of IgM at the dermoepiderrnal junction. Electron microscopy showed glomerular subepithelial depasition of eletron dense material in the kidney.

Extraskeletal chondromas are relatively uncommon benign cartilaginous tumors of the soft tissue and well known to pose a considerable diagnostic problem because of histological variations including the immature appearance of their tumor cells. Recently, we have experienced a case of extraskeletal chondroma mimicking benign chondroblastoma. The patient was a 47-year-old woman who complained of a painful subcutaneous swelling on the radial aspect of 4th proximal interphalangeal (PIP) joint in the left hand for 6 months. Radiologic examination of the 4th finger revealed a 1cm-sized soft tissue mass. Histologically, the tumor was characterized by a lobulated mass which was composed of dense proliferation of chondroblast-like cells admixed with a few multinucleated giant cells of osteoclastic type. However, there were focal areas of typical chondroma which showed lace-like intense calcification around the differentiated chondrocytes.
