PURPOSE: Prealbumin is known as a biochemical marker for assessing nutritional status, and it is influenced by a systemic inflammatory condition. This study aims to find any correlation between patients' low serum prealbumin in electrical burn and unhealed burn surface area and insufficient nutritional support. METHODS: Data were collected by a review of the medical charts of patients admitted to Hanil General Hospital for electrical burn. Laboratory results such as prealbumin, albumin, total lymphocyte count (TLC), and C-reactive protein (CRP) were collected and tested every week. Residual burn surface area (residual BSA) during a specific period was calculated from the surgery record. Statistical analysis was conducted using Pearson's correlation and multiple regression analysis. RESULTS: A total of 30 subjects were selected, all male. Average total burn surface area was 20.9±14.9%, and patients were operated on about three times after admission. There was statistical significance among all variables in Pearson's correlation test, but in multiple regression analysis, albumin and CRP were significant compared with prealbumin. CONCLUSION: The results could indicate that burn causes a systemic inflammatory reaction, which could affect the serum prealbumin level. Further study concerning the biological plausibility of each variable is needed.

The squamous cell carcinoma of the uterine cervix is the most common malignant tumor among women in Korea. Since 1976, when a research result that human papillomavirus(HPV) infection played some role in the carcinogenesis of the uterine cervical carcinoma had been published, numerous reports supporting the result have been released. Among the types of the HPV, type 16 and type 18 are classified as high risk types because they are frequently found in cervical lesions with high grade dysplasia and invasive carcinomas. However, it is impossible to ascertain by host histologic or cellular changes which type of HPV is infected. The HPV genome is composed of six open reading frames (ORF' s) named as E1, E2, E4, E5, E6 and E7 in the early region. Among these oncoproteins HPV E6/E7 have been strongly suggested to be important in carcinogenesis. When HPV infects the epithelial cells, it promotes cellular proliferation. The cellular proliferation can be evaluated by immunohistochemistry with the antibodies for proliferating cell nuclear antigen(PCNA) and Ki-67. Because PCNA has long half-life, and can be detected 48 hours after completion of mitosis, an estimation of proliferating cells by PCNA could be inaccurate. The expression of Ki-67 antigen is more correct than PCNA for the evaluation of proliferation cells due to its short half-life and rapid degradation after completion of the mitosis. In this study, immunohistochemical staining was conducted to determine the rate of expression of HPV E6, E7 and Ki-67, correlation with relationship in carcinoma in situ and invasive uterine cervical cancer. Fifty cases of carcinoma of in situ(CIS) and invasive carcinoma were immunohistochemically stained, and the results obtained were as follows: 1) E6 protein of HPV type 16/18 was expressed in 5 of 14 cases(35.7%) of carcinoma in situ, in 3 of 7 cases of microinvasive carcinoma (42.8%) and in 12 of 20 cases of invasive carcinoma(60%) but there was no significant difference in expression between the carcinoma in situ and invasive cancer group (p=0.138). 2) E7 protein of HPV type 16/18 was expressed in 10 of 14 cases(71.4%) of carcinoma in situ, in 6 of 7 cases of microinvasive carcinoma (85.7%), and in 18 of 20 cases of invasive carcinoma(90%) but there was no significant difference in expression between the carcinoma in situ and invasive cancer group (p=0.138). 3) The cell fraction expressing Ki-67 was expressed in 5 of 14 cases(35.7%) of carcinoma in situ, in 5 of 7 cases of microinvasive carcinoma (71.4%), and in 18 of 20 cases of invasive carcinoma.(90%) The cell fraction expressing Ki-67 increased according to the progress of cervical cancer. 4) There was no statistical significance between HPV type 16/18 E6 protein and the cell fraction expressing Ki-67(p=0.09). 5) There was no statistical significance between HPV type 16/18 E7 protein and the cell fraction expressing Ki-67(p=0.17). The above results suggest that the cell fraction expressing Ki-67 increases according to the invasiveness of cervical cancer and E6/E7 protein seem to play a role in the progression of cervical cancer. However we were not able to reveal a relation between E6/E7 protein and the cell fraction expressing Ki-67 in progress of cervical carcinoma, and it is recommended that further studies should be undertaken.

OBJECTIVES: Nurses working in a hospital operate in a special environment where patients require a 24-hour day service. In order to meet the need for manpower, nurses in the wards, ICU, and ER work in 3 shifts per day. This study was designed to evaluate their sleeping patterns and the factors that influence them. METHODS: The subjects were 114 female nurses working at a University Hospital in Kyungi-do. To evaluate their sleeping pattern, a survey containing 11 questions was used. Their were differentiated into insomnia, sleep deprivation, daytime sleepiness, and snoring. Statistical analysis was conducted with independent t test, chi-square test and analysis of covariance. RESULTS: A statistical difference was found between shiftworkers and nonshiftworkers, in terms of sleep initiation time (p<0.05). The occurrences of insomnia, sleep deprivation, daytime sleepiness and snoring differed between the two groups, but not significantly. CONCLUSIONS: Of the numerous factors affecting sleeping patterns, shiftwork has the most deteriorative effect.

OBJECTIVE: The purpose of this study was to evaluate the relationship between uterine size and surgical outcomes in women undergoing total vaginal hysterectomy. METHODS: We reviewed the medical records of the 170 patients who underwent total vaginal hysterectomy from February 2001 to November 2003. These patients were stratified into two groups; Group I, patients with uterine weight of between 300 gm to 1000 gm; Group II, patients with uterine weight of <300 gm. The two groups were compared for ages, parity, uterine weight, previous abdominal operations, concurrent surgical procedures, postoperative discharge day, bleeding amount, perioperative hemoglobin concentration change and operative time. RESULTS: 1. There were no significant difference between the two groups with respect to postoperative discharge day, concurrent surgical procedures, bleeding amount and perioperative hemoglobin concentration change. 2. The rate of surgical complications were similar in the two groups (Group I 12.5%; Group II 13.1%) (P=.660). 3. Operative time for vaginal hysterectomy was slightly longer for women in Group I than Group II (Group I 78.4 +/- 27.1 minutes; Group II 62.9 +/- 22.7 minutes) (P=.176), but the difference between the two groups in operative time was not statistically significant. CONCLUSION: The vaginal hysterectomy is as safe and effective for the woman with enlarged uterus (300-1000 gm) as for the woman with uterine weight of <300 gm. Uterine enlargement (uterine weight > 300 gm) is not an absolute contraindication to vaginal hysterectomy.

BACKGROUND/AIMS: Periostin is an extracellular matrix protein and is known to be related to the metastatic potential and prognosis of cancer. However, few studies have investigated the expression level of periostin and its association with prognoses in hepatocellular carcinoma. Therefore, we analyzed periostin overexpression in hepatocellular carcinoma and its implication for prognoses. METHODS: We evaluated 149 patients who underwent surgical resection between 2006 and 2010. Tissue microarrays were constructed from hepatocellular carcinoma tissue and adjacent nontumor tissue, and immunohistochemistry was performed. RESULTS: A high periostin level was observed more frequently in cases of multiple tumors (odds ratio [OR], 2.826; 95% confidence interval [CI], 1.224 to 6.527; p=0.013), positive microvascular invasion (OR, 2.974; 95% CI, 1.431 to 6.181; p=0.003), and advanced stage disease (OR, 3.032; 95% CI, 1.424 to 6.452; p=0.003). Patients with high periostin expression had significantly (p=0.002) lower overall survival rates than those with low periostin expression (90.3%, 66.1%, and 56.2% vs 97.7%, 85.1%, and 77.5% at 1, 3, and 5 years). CONCLUSIONS: We found that a combination of periostin overexpression and microvascular invasion in hepatocellular carcinoma was correlated with a poor prognosis and can be a good prognostic marker for hepatocellular carcinoma.

Primary carcinoma of the fallopian tube is the rarest cancer of the female genital tract with an incidence of 1% all gynecologic tumors Moreover, adenocarcinoma in situ of fallopian tube accounts for approximately 1% of primary fallopian tube cancer. Ovarian cancer and primary carcinoma of the fallopian tube are similar in many aspects. Both carcinomas show an increase incidence among nulliparous women, are often of serous papillay histology, and they have not only a poor pronosis with stage and residual tumor size as important prognostic factors, but also respond to paclitaxel-based treatment. Nevertheless, presenting symptoms are variable and nonspecific, so pre-operative diagnosis of fallopian tube carcinoma is seldom made. We have experiened a case of primary adenocarcinoma in situ of fallopian tube and reported with brief review of literature.

BACKGROUND/AIMS: Pegylated interferon (peginterferon) and ribavirin combination therapy is less effective and associated with a higher frequency of serious complications in chronic hepatitis C patients with cirrhosis than in noncirrhotic patients. This study evaluated the efficacy and tolerability of peginterferon and ribavirin treatment in patients with hepatitis C virus (HCV)-related cirrhosis. METHODS: Eighty-six patients with clinically diagnosed liver cirrhosis were treated with either peginterferon alpha-2a (n=51) or peginterferon alpha-2b (n=35) plus ribavirin. The sustained virologic response (SVR) and adverse effects were analyzed retrospectively. RESULTS: Of the 86 patients (55 males), 48 patients (55.8%) had HCV genotype 1 infection and 38 (44.2%) had genotype non-1 infection. The overall SVR rate was 34.9% (30/86), and the rates of SVR in the genotype 1 and non-1 patients were 20.8% (10/48) and 52.6% (20/38), respectively. The multivariate analysis revealed that having HCV genotype 1 (P=0.003) and high baseline viral load (>8.0x10(5) IU/mL, P=0.012) were the independent predictive factors for SVR failure. In 20.9% (18/86) of the patients, treatment was not completed due to adverse events (27.8%), loss to follow-up (50.0%), and other reasons (22.2%). CONCLUSIONS: Peginterferon and ribavirin combination therapy was relatively effective and feasible for clinically diagnosed HCV patients, especially in those with genotype non-1 infection and low baseline viral load.
