PURPOSE: DNA mismatch repair gene is responsible for hereditary nonpolyposis colorectal cancer. But it is not well known its role in sporadic colorectal cancer patients. We analysed normal hMSH2, hMLH1 protein expression in colorectal adenocarcinoma tissues and corresponding normal tissues to find out the role of mismatch repair gene in sporadic colorectal cancer by Western blotting. METHODS: Normal hMSH2 and hMLH1 protein expression was studied on 25 colorectal cancer and corresponding normal tissue by Western blot with hMSH2 and hMLH1 monoclonal antibody. Normal protein band was expressed on 100 kD in hMSH2 and 87 kD in hMLH1. SW480 and LoVo cell line was used as positive and negative control for hMSH2 and LoVo and SW480 as positive and negative for hMLH1. And we analysed the relation between the hMSH2, hMLH1 protein expression and clinicopathological parameters. RESULTS: It was 2 cases (8%) that both hMSH2 and hMLH1 protein expression was not observed. Three cases (12%) were negative for hMSH2 and 2 cases (8%) for hMLH1. One or both hMSH2, hMLH1 protein expression was not observed in 7 cases (28%) in total. There was no correlation for proximal occurrence (25% vs 35%), young age (37.5% vs 23.5%) and lymph node metastasis (50% vs 47%). But poorly and mucinous differentiation was regarded as having relation with negative expression of hMSH2 and hMLH1 (50% vs 17.6%) but not significant statistically. CONCLUSION: Sporadic colorectal cancer with negative expression of normal hMSH2 and hMLH1 protein showed no relation to younger age, proximal site preference and lymph node metastasis. But it was suggested that mismatch repair gene protein was involved in cancer cell differentiation in sporadic colorectal cancer.

The use of subcutaneously tunneled, cuffed central venous catheters like Broviac's or Hickman's has increased and complications related to catheter removal has also increased. However, there are only few reports of complications that occur at the time of removal. The authors report an unusual case of catheter fracture during removal of Broviac catheter.

Apocrine sweat gland carcinoma is a very unusual malignant skin adnexal tumor and mostly occurs in areas where apocrine elands are abundant namely. axilla. upper arm. scalp. eyelid. vulva and external auditory meatus. The scrotal location is not yet reported. We report a case of apocrine sweat gland carcinoma of scrotum in a man aged 85, which was managed by local excision. The histologic finding is that of poorly differentiated adenocarcinoma. Evidence of decapitation secretion typical or apocrine glands. is present in some areas.

PURPOSE: We performed this study to define the characteristic mammographic and ultrasonographic findings in lower risk lesions of fibrocystic change and also tried to evaluate the role of both modalities in planning the treatment of these lesions. MATERIALS AND METHODS: We retrospectively reviewed 38 cases of mammography and 46 cases of ultrasonography in biopsy proven 55 cases of fibrocystic change, histologically showing the nonproliferative pattern or proliferative pattern without atypia. We analyzed the mammographic and ultrasonographic findings, final assessments, and compared the effectiveness of each modality. RESULTS: On mammography, there were no abnormalities in 20 cases(53%), nodules or masses in 9 cases(24%), microcalcifications in 6 cases(16%) and asymmetric density in 5 cases(14%). On ultrasonography, there were 40 cases(87%) of focalsonographic abnormality and no abnormality in 6 cases(13%). Most focal sonographic abnormalities were smooth(40cases, 93%), well-defined(21 cases, 49%) or ill-defined(22 cases, 51%) round or oval(36 cases, 84%) shaped, homogeneous(31 cases, 67%), hypoechoic(30 cases, 65%) lesions. Final assessment revealed that only 7 cases(18%) of mammography and 8 cases(18%) of ultrasound examinations were included into the category of indeterminate and malignancy groups which were recomended biopsy. Mammography was excellent to demonstrate the microcalcifications and ultrasonography was effective in depiction of the focal lesions. CONCLUSION: The mammography and ultrasonography findings were not specific in diagnosing lower risk group of fibrocystic change. But complementary study of both modalities in conjunction with clinical findings will be helpful in making decinion amary biopsy, fine needle aspiration, and simple close follow up of the lesions.

To determine the perinatal mortality and morbidity of fetuses with absent end-diastolic velocities (AEDV) of the umbilical artery in severe pre-eclampsia and eclampsia, the outcome of 5 fetuses with AEDV was compared with that of 35 fetuses with positive end-diastolic velocities (PEDV). The study population comprised 38 cases of severe pre-eclampsia and 2 cases of eclampsia with structurally normal singletons, who had had umbilical artery Doppler velocimetry weekly from admission to delivery. The Doppler velocimetry result was not used for the clinical management. Perinatal death and neonatal morbidity from both groups were further examined in gestational age category to control the influence of preterm births. The incidence of AEDV of the umbilical artery Doppler velocimetry in severe pre-eclampsia and eclampsia was 12.5% (5/40). The AEDV group had a significantly higher incidence than the PEDV group in terms of ceasarean section due to fetal distress (60% : 17%), Apgar score < 7 at 5 minutes (60% : 14%), perinatal death (25% : 0%) and assisted mechanical ventilation (67% : 9%) both at 32-36 weeks. Time intervals from the detection of AEDV to delivery of live neonates varied from the day to 15 days. In conclusion, AEDV in the umbilical artery might be of clinical value in routine surveillance of pregnancies complicated by severe pre-eclampsia and eclampsia, and predict hypoxic fetal condition which needs operative interventions before or during labor and mechanical ventilation after birth.

PURPOSE: This study was performed to identify the characteristic findings of miliary pulmonary tuberculosis on HRCT and to evaluate the usefulness of HRCT by compareson with chest radiographs. MATERIAL AND METHODS: High resolution CT, chest radiographs and medical records were retrospectively reviewed in 10 patients with miliary pulmonary tuberculosis. We analysed the size, distribution and margin of nodules, reticular or ground-glass density, parenchymal lesion, mediastinal lymphadenopathy and pleural effusion on HRCT which were compared with chest radiographic findings. RESULTS: On HRCT, characteristic 1--2mm sized sharp or ill-defined nodular densities were randomly distributed throughout both lungs in all cases. In seven cases, the nodules were evenly scattered, but slightly more in upper lung zone in two cases, and in lower in one case. Only three cases revealed somewhat large and abundant nodules in posterior lung zone. There were findings of ill-defined margin of nodules in three cases, reticular densities in three cases and ground-glass opacity in two cases, all of which were observed within 4 weeks after onset of symptom. In one case, HRCT scan revealed a micronodular pattern in the lung parenchyma, even though chest radiographs of 2 days before were not obviously abnormal. HRCT was better to evaluate the margin of nodule and distribution than chest radiographs in four cases. Focal parenchymal lesion (n=5), pleural effusion(n=4), mediastinal lymphadenopathy(n=6) and ARDS(n=I) were also associated. CONCLUSION: HRCT could suggest a more specific diagnosis of miliary pulmonary tuberculosis with the above characteristic findings in appropriate clinical setting and normal or interstitial pattern of chest radiographs.

OBJECTIVES: Recently, it was suggested that apoptosis may be a basic mechanism of follicular atretic process. If the POF(premature ovarian failure) results from an acceleration of the process of atresia of the oocytes causing premature deletion of stored oocytes, POF may be a good model for the apoptosis. Our objective is to determine the relation between the POF and apoptosis. METHODS: We performed laparoscopic ovarian biopsy in 17 patients with POF. We evaluated the ovaries from a patient with POF by conventional H-E stining and immunohistochemical staining for apoptosis related protein(bcl-2, bax, fas and fas-L). RESULTS: Atretic cystic follicles were seen 4 out of 17 patients, and corpora albicans indicating past ovulation were seen 9 out of 17 patients. Primordial follicles were seen in 3 out of 17 patients, however developing follicles were not seen in all patients. Immunohistochemical analysis revealed that Bax was expressed in the lining cells of the atretic cystic follicle and primordial follicle and mesothelial cells lining the surface of the ovary. Fas and Fas-L were expressed on the lining pregranulosa cells and primary oocyte of the primordial follicle in the ovary of the patient with premature ovarian failure. Bax were also expressed on the lining pregranulosa cell and oocyte of the premature ovarian failure. Bcl-2 was expressed in the lining cells of primordial follicles of the patients with POF. CONCLUSION: Apoptosis may be a basic mechanism of POF. Bax, fas and fas-L may play a role causing premature follicular depletion.

Parricide, the crime of murdering a parent, accounts for about 5% of all homicides. Filicide is the crime of murdering one's own child. This study aimed to review demographic features and criminal characteristics of individuals who committed parricide and filicide in Republic of Korea (ROK). This study is based on data from the Korea Police Crime Analysis System, from 2006~2013. We assessed the diverse characteristics of both victims and perpetrators. Over the selected period, 381 parents were killed by their children and 230 children were killed by parents in the ROK. Parricides caused by schizophrenic murders accounted for 39.6% of all cases. Moreover, approximately 44.4% of the perpetrators attempted suicide following the maternal filicide. In our findings, psychiatric illness was a very important predictor in parricide, and these further suggest that young mothers with severe mental illness require careful monitoring by mental health support service.

PURPOSE: To compare quantitative polarimetric measurements in eyes with NTG and HTG using GDx-VCC. Both groups were matched by age and glaucoma stage based on the Humphrey visual field test. METHODS: We retrospectively reviewed the records of 146 patients who underwent Humphrey field analysis (HFA) and GDx-VCC. We compared outcomes of retinal nerve fiber layer (RNFL) parameters among the three groups by ANOVA and between each pair of groups using the Tukey-Kramer Post-Hoc test. We also evaluated the sensitivity and specificity of GDx-VCC in detecting glaucoma in each group. RESULTS: The mean age and HFA mean deviation (MD) were 55.6+/-9.5 years and -0.8+/-1.5 dB in 47 control patients, 59.4+/-9.0 years and -5.77+/-4.38 dB in 49 NTG patients, and 59.4+/-11.7 years and -8.09+/-6.77 dB in 51 HTG patients, respectively. All thickness parameters were lower in HTG patients compared to NTG patients, but there were no significant differences in ratio parameters between age-matched early HTG and NTG patients. The sensitivity of GDx-VCC was significantly higher in both early and total HTG patients compared to the respective groups of NTG patients. CONCLUSIONS: Compared to eyes with NTG, eyes with HTG showed reduced RNFL thickness and ratio parameters when patients were age and visual field matched. GDx-VCC appeared to be more sensitive in detecting RNFL damage in HTG patients.
