Epidermal growth factor receptor (EGFR) is an intergral membrane protein. Overexpression or mutation of EGFR may play a role in careinogenesis. Recently, many molecular biologic techniques have been used to study expression of oncogenes. One of them, in situ mRNA hybridization, using paraffin embedded blocks, offers a unique means to allow precise localization within histological preparations, and also overcomes problems relating to translation defects and abnormal translation. In order to confirm the usefulness of epidermal growth factor receptor as a tumor marker, and to compare the expression of EGFR between in situ MRNA hybridization and an immunohistochemical study, in situ MRNA hybridization was performed along with an immunohistochemical study for EGFR in paraffin sections of 84 uterine cervix carcinomas. A positive reaction for EGFR was observed mairdy in the cytoplasm of tumor cells. The vascular muscle layer and uterine muscle tissue around the cancer nest revealed a positive reaction in immunohistochemical stain for EGFR, with a negative reaction for EGFR mRNA. In the cancer nests, the immunohistochemical positive reaction for EGFR was strong in differentiated cells and keratin pearls, but a strong positive reaction for EGFR mRNA was localized in undifferentiated cells. The overall positive of immunostaing for EGFR was 77% for uterine cervix carcinoma; 71 % for carcinoma in situ, 71 % for microinvaseve carcinoma, and 89% for invasive carcinoma. The overall positivity of EGFR from in situ MRNA hybridization was 94% of the uterine cervix carcinoma; 93% for carcinoma in situ, 93% for microinvasive carcinoma, and 96% for invasive carcinoma. From these results, EGFR is a useful tumor marker for uterine cervix carcinoma, and in situ mRNA hybridization has greater sensitivity and specificity than immunohistochemistry.

An immunohistochemical and electron microscopic study of an atypical fibroxanthoma of the skin (AFX) was reported. The lesion developed on the left scapulararea in a 70-year-old man. The result using antibody to S-100 protein was negative and the tumor cells observed with electron microscope were undifferentiated, fibroblast-like, histiocyte-like and multinucleated giant cells. But Langerhans-like cells or Langerhans were not found.

Immunohistochemical staining on paraffin sections for S-100 protein improved diagnostic accuracy for melanocytic tumor. But specificity of S-100 protein in the diagnosis of melanocytic tumor is very low, because S-100 protein was also expressed in neurogenic tumor and salivary gland tumor. To investigate a specific tumor marker for the malignant melanoma, immunohistochemical staining for HMB-45 and S-100 protein was performed on the paraffin sections of 25 cases of malignant melanoma and 46 cases of nevi. Positive reaction for HMB-45 and S-100 protein was diffusely identified in the cytoplasm of tumor cells. Positive ratio for HMB-45 was 100% in malignant melanoma, 92% in junctional component of compound nevus and 0% in intradermal nevus. Positive ratio for S-100 protein was 92% in malignant melanoma, 100% in compound nevus and 100% in intradermal nevus. The sensitivity and specificity for HMB-45 in malignant melanoma were 100%, but those for S-100 protein were 92% in sensitivity and 86.7% in specificity. These results indicate that HMB-45 has a high sensitivity and specificity for malignant melanoma cells and it can be quite useful for the histopathological diagnosis of malignant melanoma.

Gastrointestinal cytomegalovirus(CMV) infection in adults is observed as a part of a generalized or localized infection in patients who are immunocompromized. We report a case of CMV infection of the small intestine. The patient is a 34 year-old woman who has complained of palpable purpura in the lower extremities and buttocks, and arthralgia of large joints. The skin biopsy showed fibrinoid necrosis and neutrophils with leukocytoclasis, which findings are compatible with hypersensitivity angiitis. The patient received steroid and cyclophosphamide. During the follow-up period, generalized edema and bloody stool were detected. Resected specimen of small bowel has multiple aphthous ulcer. Microscopically, cytomegalic cells are observed along the endothelial cells and mesenchymal cells. In situ hybridization using DNA probes against CMV revealed positive staining in the cytomegalic inclusions in vascular endothelial and mesenchymal cells.

Fibrohistiocytic tumors are a diverse group of benign and malignant soft tissue lesions, including dermatofibroma, dermatofibrosarcomaprotuberans, and malignant fibrous histiocytoma. On the clinical point of view, the distinction between benign and malignant lesions and malignancy grading is far more important. Therefore, we investigated 23 fibrohistiocytic tumors, using PCNA (PC10) which was a useful marker of proliferating activity, to differentiate the benign lesions from the malignant and correlate with other prognostic factors including tumor necrosis. cellularity, histologic grade, and mitotic counts. The results obtained were as follows 1) Positive tumor cells were clearly identified by the characteristic diffuse or granular nuclear staining. 2) The number of PCNA-positive tumor cells were 2.16+/-2.39% in dermatofibroma, 16.12+/-7.38% in dermatofibrosacoma protuberans, and 28.02+/-17.47% in the malignant fibrous histiocytoma. The numbers of PCNA-positive tumor cells in the malignant lesions higher than in the benign (p<0.001). 3) Deep seated, large size (>5 cm) and recurred or metastatic cases of MFH were more the high PCNA index (more than 20%) than the low index (less than 20%) groups. 4) PCNA index in MFHs had positive correlation with the number of mitotic counts (r=0.7582, p<0.001), cellularity (r=0.5908, p<0.05) and histologic grade (r=0.4164, p<0.05). These results suggested that reactivity on PCNA might assist in the distinction between benign and malignant lesions in fibrohistiocytic tumors, and could be a useful prognostic factor in the patients with malignant fibrous histiocytoma.

Although urinary tract infections are common in adults, pyelonephritis is rarely considered in the differential diagnosis of acute renal failure. Acute pyelonephritis without urinary tract obstruction, previous renal diseases or septic shock is a rare cause of acute renal failure. Despite appropriate antibiotic therapy, recovery of renal function could be slow and incomplete. We experienced a 45 year-old woman with diabetes who developed bilateral acute pyelonephritis followed by acute renal failure. The renal biopsy revealed diffuse edematous and focal fibrotic inters- titium with infiltration of lymphocytes compatible with interstitial nephritis. Although her renal function improved gradually with antimicrobial treatment, the process was incomplete and renal dysfunction persisted at about 10-month follow-up, suggesting permanent renal damage. Therefore, we report this case with brief review of related literature.

BACKGROUND: Discrepancies exist in the existing researches regarding the association between social capital and self-efficacy, and most of these researches have been done in developed countries. The aims of this study were to assess the independent association between individual social capital and self-efficacy and to assess the associations between individual social capital, self-efficacy and self-rated health. METHODS: Data were obtained from the Gyeongnam health survey (6,500 persons) conducted in 2008. A self-administered questionnaire was additionally administered to gather information on demographic variables, health behaviors, chronic diseases, self-efficacy, social capital, and self-rated health status. Total study population was 3,843 as those with chronic diseases were excluded. RESULTS: In males, trust was positively associated with confidence and preference to task difficulty, and participation was negatively associated with confidence and positively associated with regulation and preference to task difficulty. In females, trust was positively associated with confidence and preference to task difficulty and negatively associated with regulation. Participation was positively associated with preference to task difficulty. In males, the odds for self-rated health status was better for persons with confidence (95% confidence interval, CI 1.088-1.705), trust (95% CI 1.172-1.821) and participation (95% CI 1.268-2.117). In females, the odds for self-rated health status was better for those with confidence (95% CI 1.250-1.803), preference of task difficulty (95% CI 1.019-1.683) and participation (95% CI 1.024-1.555). CONCLUSIONS: High social capital measured at an individual level may promote self-efficacy and health status.

BACKGROUND: Hypothermia is a condition that can lead to serious complications and even to death in newborn. Although the temperature control is essential in neonatal care, it is often neglected during urgent transfer from local private hospitals. The purpose of this study is to evaluate the incidence and clinical outcomes of transfer induced neonatal hypothermia. SUBJECTS AND METHOD: In this retrospective study, subject is limited to transferred outborn babies with age less than 24 hours from June 1996 to May 1999. A total of 3,086 patients were admitted in NICU during the study period and inborn and outborn babies were 1,743(56%) and 1,343(44%) respectively. Among the 1,343 outborn babies, 212 babies were transferred from the private hospital within 24 hours of birth and were eligible for the study. Rectal temperature on arrival, transfer time, birth weight, gestational age, initial arterial gas study, and clinical outcome were compared. Statistical analysis has been done with chi-sqaure test and multiple logistic regression analysis. RESULTS: There were 84 cases(39.6%) hypothermia(<36degrees C> among the 212 babies and the rate of hypothermia in transfered babies have not decreased over the study period. There were significantly more hypothermia in lower gestational age (less than 28 weeks) and lower birth weight (less than 2,000gm) caused hypothermia significantly more than normal gestational age or normal range of birth weight. And time interval (less than 12 hour) from birth to arrival at emergency department was also significant factor in hypothermia. The mortality rate was three fold higher in hypothermia than normothermic or hyperthermic babies. CONCLUSION: This study shows that hypothermia during neonate transportation is a major cause of neonatal mortality and morbidity in prehopital care. Body temperature control during transport of neonates under 24 hours of age should be emphasized for the better outcome of treatment.

Juvenile xanthogranuloma(JXG) is a a benign histiocytic proliferative disorder most frequently seen in infants. The usual course is self-limited, but it may be a manifestation of juvenile chronic myeloid leukemia(JCML). In addition to JXG, some patient with JCML may have multiple cafe-au-lait spots and a family history of neurofibromatosis(NF). The association of JXG and cafe-au-lait spots in patients with JCML is of interest in light of description of otherwise healthy children with JXG who also had cafe-au-lait spots. We report herein a case of JXG in 18-month-old boy who also had multiple cafe-au-alit spots, which predated the JCML.
