PURPOSE: Various prognostic indicators have been identified for mammary carcinomas, but the issue of their significance remains unsettled. The prognostic impact of c-erb B2, Ki-67 and topoisomerase II alpha expression was investigated in relation to prognostic factors for carcinomas of the breast and to the tumor cell growth fraction. METHODS: One hundred eighteen cases of invasive mammary carcinoma were investigated by immunohistochemical staining for c-erb B2, topoisomerase II alpha, and Ki-67. Clinicopathologic parameters were compared with the expression pattern and incidence of c-erb B2, topoisomerase II alpha and Ki- 67 in invasive mammary carcinoma. RESULTS: C-erb B2 showed significant correlation with topoisomerase II alpha (P<0.05), but others were not significant. Topoisomerase II alpha and Ki-67 index closely paralleled each other, indicating that both reflect the proliferate activity of tumor cells and were associated with high nuclear and histological grade, ER and PR expression (P<0.05). CONCLUSION: These results indicate that ki-67 and topoisomerase II alpha proteins might play a role in tumor progression of breast carcinoma. The Ki-67 and topoisomerase II alpha index may be proliferate factors of breast cancer. In addition, the increase expression of Ki-67 and topoisomerase II alpha and hormone receptor were closely correlated each other, and could be used as factors suggesting poor prognosis in breast carcinoma.

Hidroacanthoma simplex is a benign tumor believed to arise from the uppermost segment of the intradermal eccrine duct and the acrosyringium, and histologically shows intraepidermal focal growth. A malignant counterpart to this tumor is rare and named malignant hidroacanthoma simplex or porocarcinoma in situ. We report a case of atypical hidroacanthoma simplex, which is considered to be a malignant transformation of benign hidroacanthoma simplex in a 83- year-old female.

We evaluated gastric emptying time (GET) by using Tc99m-sulfur colloid gastric emptying scintigraphy in 11 patients with CAPD (6 male, 5 female) and 14 healthy volunteers. We investigated the effect of dialysate dwelling on GET by studying twice, once without dialysate in the abdomen (drained) and once with 2 L of dialysate in the abdomen (full), and the relationship between body surface area (BSA) and delayed gastric emptying. 1) The mean of gastric emptying rate in 120 minute in patients with CAPD when drained (67.8+/-13.4%) was not different from that in healthy volunteers (65.4+/-8.6%) 2) The mean of gastric emptying rate in 120 minute when full (55.6+/-14.6%) was significantly lower than that when drained (67.8+/-13.4%) (P<0.05). In four of the 11 patients (36.4%), gastric emptying was extremely delayed from normal to abnormal range when full. 3) The BSA (1.5+/-0.11m2)of patients who had extremely delayed GET from normal to abnormal range was smaller than that (1.74+/-0.22m2) of patients who had minimal delayed or unchanged GET when full. This study showed the patient with CAPD had normal gastric emptying when drained, and that gastric emptying was delayed by dialysate dwelling, especially in the patients who has less than 1.5m2 of body surface area. Therefore, we suggest that intermittent nocturnal peritoneal dialysis or a small volume of dialysate may be considered for the patient with small body surface area based on the adequacy.

Cockcroft and Gault's formula is frequently used to estimate creatinine (Ccr) in clinical practice. To determine the accuracy of such estimation in Korean patients, we measured simultaneously, serum creatinine and 24-hour urinary creatinine excretion in 696 Korean patients (male:350, female:346). Measured Ccr was significantly different from estimated Ccr in several age groups and the decrease of creatinine excretion with age is less than Cockcroft and Gault's estimation. We assumed that this difference can be due to difference of the body habitus and difference of urinary creatinine excretion per body weight between different races. So we divided the sample population into two groups and derived the new formula in one group with regression analysis between age and 24 hour urinary creatinine excretion per body weight for estimation of Ccr as Cockcroft and Gault derived their formula and applied it to another group to compare the new formula with Cockcroft and Gault's formula in Korean patients. The new formula was Ccr (mL/min)=[ (260-age)x weight (kg)]/[160 x serumCr (mg/dL)] for male and Ccr (mL/min)-[ (236-age) x weight (kg)]/[180 x serum Cr (mg/dL)] for female. Predictive accuracy of the new formula was significantly better than the Cockcroft and Gault's formula in the other sample population and also in subgroup of the patients with azotemia.

BACKGROUND: The urinary protein to creatinine ratio in a single voided random urine sample has been widely used as an estimation of 24 hour urine protein excretion because of inconvenience and frequent collection errors during timed collection of 24 hour urine. But the protein to creatinine ratio also showed frequent estimating error, overestimation or underestimation. We thought that protein to creatinine ratio adjusted by daily creatinine excretion estimated by Cockroft-Gault equation can be more accurate than protein to creatinine ratio and compared them as follows. METHODS: This study consisted of 81 patients whose 24 hour urine protein excretion and random spot urine protein to creatinine ratio were measured concomitantly. There was no significant change of body weight or serum creatinine change around the study day. The modified protein to creatinine ratio could be estimated from the measured protein to creatinine ratio in a random spot urine sample by multiplying the ratio by the expected daily creatinine excretion estimated by Cockroft-Gault equation. These results were compared with well collected 24 hour urine protein. RESULTS: The difference between protein to creatinine ratio and 24 hour urine protein was 0.87+/-1.13, on the other hand, the difference between modified protein to creatinine ratio and 24 hour urine protein was 0.52+/-0.65 (p<0.05). Correlation coefficients between protein to creatinine ratio, modified protein to creatinine ratio and 24 hour urine protein were 0.877, 0.957 respectively. CONCLUSION: The protein to creatinine ratio modified by the expected daily creatinine excreation rate calculated by Cockfort-Gault equation was more accurate than simple protein to creatinine ratio.

BACKGROUND: Human nails bear longitudinal furrows on both upper and lower surface. These furrows are formed as the nails grow and correspond to parallel dermal ridges irregularly distributed on the nail bed. Often there is fungal invasion in a longitudinal narrow band according to the furrows of the nail bed, clinically recognized streak type onychomycosis. OBJECTIVE: Our purpose was to investigate the clinical features, causative organisms, and predisposing factors and to evaluate the treatment responses of oral antifungal agent in streak type onychomycosis. METHODS: The study was conducted with 387 cases of onycomycosis (45 cases of streak type, 342 cases of non-streak type) and 50 normal controls examined at Department of Dermatology, Hanyang University Guri Hospital from June, 2001 to May, 2004. Streak type onychomycosis was devided into three clinical presentations: distal type (20 cases), lateral type (19 cases), and multiple type (6 cases). RESULTS: In the groups of distal and multiple type of streak type onychomycosis, the longitudinal nail furrows were deep compared to the groups of non-streak type onychomycosis and normal control (p< 0.05). In the group of distal type of streak type onychomycosis, the tinea pedis severities were low compared to the group of non-streak type onychomycosis (p< 0.05). There was no statistically significant difference when comparing the nail growth rate of the groups of streak type onychomycosis, non-streak type onychomycosis, and normal control (p> 0.05). In the groups of distal and lateral type of streak type onychomycosis, the treatment responses were poor compared to the group of non-streak type onychomycosis (p< 0.05). CONCLUSION: Treatment response is poor in streak type onychomycosis, therefore, extra treatments in addition to oral antifungal agents should be considered. If the patients who have deep longitudinal nail furrow are affected with tinea pedis, effective therapies in early stage should be considered to prevent to progress to streak type onychomycosis.

BACKGROUND: This study aimed to research on how adherence and blood control could make a difference when it comes to develop complications. METHODS: The study's subjects were 255,916 patients who were newly diagnosed with hypertension in 2009 using data collected by National Health Insurance Cooperation. Patients are considered as a group under adherence if visit days and prescription days are more than 300 days. Patients are considered to have successfully controled their hypertension based on actual value measured by National Health Insurance Cooperation and the study takes a look at whether they were diagnosed with complications of cerebrocardiovascular disease in 2012. Chi-square test and logistic regression was used to analyze. RESULTS: Patients who were able to control their hypertension show 0.80 times chance of developing cerebrovascular disease, and 0.89 times chance of developing cardiocerebrovascular disease. The group of adherence shows lower chance of developing complication in general than the group of non-adherence. CONCLUSION: The study revealed that hypertension's constant treatment could control the blood pressure and prevent complications. It is important that encourages patients to effort for persistent treatment for reducing complication.

Diarrea-associated hemolytic uremic syndrome (HUS) is very rare in adults. Few reports are available on clinical features and plasma exchange in adult patients with diarrhea-associated HUS in Korea. We retrospectively examined the records of five adult patients with diarrhea-associated HUS admitted to Samsung Seoul Hospital between January 1995 and December 1997. If the patient had neurologic abnormalities, or there was rapid clinical deterioration, with the hematocrit decreasing below 20%, the platelet count falling below 10,000/mm3, the creatinine concentration increasing above 5.0 mg/dl, plasma exchange was begun. There were 4 females and 1 male. Patients ranged in age from 16 to 61 years. All patients presented with diarrhea and abdominal pain, and 3 patients had bloody diarrhea. The mean time between the onset of diarrhea and thrombocytopenia was 4.4+/-1.9 days (range, 1 to 6). All patients received 7 to 24 plasma exchanges. The mean exchanged plasma volume was 1.1+/-0.2 times of patients own plasma volume. The pattern of clinical response to plasma exchange was initial normalization of platelet count (8.0+/-3.8 days), followed by normalization of LDH level (20.2+/-14.5 days) and creatinine concentration (25.8+/-13.8 days). Metabolic alkalosis developed in two patients undergoing daily plasma exchange. We successfully managed the metabolic alkalosis with continuous venovenous hemofiltration. The mean duration of hospitalization was 28.8+/-11.2days (range, 20 to 42). All patients successfully recovered without any sequale. Although this study is based on small case series, we suggested that plasma exchange may improve the outcome in adult diarrhea-associated HUS.

OBJECTIVE: To determine the prevalence of denervation potentials from the foot intrinsic and the lumbosacral paraspinal muscles in asymptomatic persons in Korea. METHOD: Nerve conduction studies were performed in 80 asymptomatic persons at sural, peroneal and tibial nerves. We excluded 15 persons with abnormal values of nerve conduction studies. In our study, 36 males and 29 females participated and the mean age of subjects was 52.9 years. We checked denervation potentials from unilateral lumbosacral paraspinal (L4-S1) and foot intrinsic muscles (abductor hallucis and extensor digitorum brevis muscle) by needle EMG. RESULTS: The prevalence of denervation potentials from foot intrinsic muscles was 3% (2 cases out of 65 asymptomatic subjects). Denervation potentials consisting of a positive sharp wave were seen from the abductor hallucis muscle. No subjects showed any denervation potentials from the lumbosacral paraspinal muscles in our study. Abnormal X-ray findings were seen in subjects who had denervation potentials from the foot intrinsic muscles. CONCLUSION: The prevalence of denervation potentials from the foot intrinsic and the lumbosacral paraspinal muscles in asymptomatic person was not as high as previously reported
