ABSTRACT
Research on physical activity and health is actively being conducted. In the Korea National Health and Nutrition Examination Survey (KNHANES), the Global Physical Activity Questionnaire (GPAQ) was newly introduced in 2014. The purpose of this study was to investigate the levels of physical activity and related factors in Koreans who were assessed through the GPAQ by dividing the physical activity by occupation, leisure, and transport domain. This study used data from the KNHANES (2014–2016), the study population of which included 17,357 participants aged 12 to 80 years. We compared the differences in physical activity by sociodemographic factors, health-related factors, and psychological health-related factors. Moreover, we also compared the mean metabolic equivalent of task and daily sitting time according to physical activity domain by sex and age group. Finally, we investigated the sociodemographic factors, health-related factors, and psychological health-related factors that significantly affect the average physical activity per week. The various factors were found to differ in the frequency of physical activity levels. In addition, there was a difference in the amount of physical activity per occupation, leisure, and transport domain in each age group. Finally, age, sex, high-density lipoprotein cholesterol levels, arthritis, allergic rhinitis and sinusitis, sleeping time, and perceived health status significantly affected physical activity. The levels of physical activity significantly differed by sociodemographic factors, health-related factors, and psychological health-related factors. There was also a difference in the physical activity levels according to the age and sex per each domain of physical activity.

BACKGROUNDS/AIMS: Combined hepatocellular carcinoma and cholangiocarcinoma (cHCC-CC) is an uncommon subtype of primary liver cancer that has rarely been reported in detail. This study was performed in order to evaluate the clinicopathological characteristics and prognostic factors of cHCC-CC in single center. METHODS: The clinicopathological features of patients diagnosed and operated with cHCC-CC at Chonbuk National Hospital between July 1998 and July 2007 were retrospectively studied by comparing them with patients with only hepatocellular carcinoma (HCC) who had undergone a hepatic resection during the same period. RESULTS: Ten out of 152 patients who had undergone a hepatic resection were diagnosed with cHCC-CC and thus included in this study (M : F=8 : 2, median age: 52+/-11.1 years). According to the parameters of the 7th American Joint Committee on Cancer T staging, there were 76 (50.0%), 44 (28.9%), 9 (5.9%), 18 (11.8%) and 5 (3.3%) patients with T stages 1, 2, 3a, 3b and 4, respectively. The overall survival period was longer in the HCC only group (68+/-40.4 months) than in the combined cHCC-CC group (23+/-40.1 months) (p<0.0001). The 5-year survival rate was 10% in the cHCC-CC group and 60% in the HCC group (p<0.0001). The disease free survival for patients with cHCC-HCC and HCC were 16+/-37.4 and 51+/-44.3 months, respectively (p<0.0001). Univariate analysis revealed that age, gender, transarterial chemoembolization (TACE), and T stage were statistically significant in terms of patient's overall survival. However, there were no significant clinicopathological factors identified by the multivariate analysis. CONCLUSIONS: Even after the hepatic resection in the HCC, the prognosis is poorer if the patient has cholangiocellular components compared to the usual HCC.

BACKGROUNDS/AIMS: The aim of this study is to analyze surgical outcomes and prognostic factors affecting survival after surgical resection in patients with gallbladder cancer. METHODS: We retrospectively reviewed 86 patients treated surgically for gallbladder cancer from January 2000 to December 2009 at Chonbuk National University Hospital. Clinicopathologic factors, surgical treatment and outcome data were analyzed. RESULTS: Among the 86 patients (44 male, 42 female) with gallbladder cancer, the mean age was 62.9 years (range: 32-80) and the median survival was 42.4+/-3.5 month. The overall cumulative survival rates of 86 patients were for 1 year, 83.7%; 3 year, 67.4%; 5 year survival, 61.7%. Univariate analysis revealed that preoperative serum alanine aminotransferase, alkaline phosphatase, total bilirubin, carcinoembryonic antigen (CEA), T staging, N staging were statistically significantly associated with survival. CEA (p=0.004) and T staging (p=0.005) were associated with survival in multivariate analysis. Two-year survival rates were analyzed according to the methods of surgical resection, with simple cholecystectomy showing 100%, whereas extended cholecystectomy showed about 83% in T1b. We could not find out any adverse effect of the simple cholecystectomy for survival. CONCLUSIONS: CEA and T stage are independent significant prognostic factor associated with patient survival in our study. Simple cholecystectomy can be regarded as curative resection in stage T1b. Longer observation periods and more cases will be needed to confirm these conclusions.

OBJECTIVE: We have assessed the accuracy of frozen section diagnosis and the outcomes of misdiagnosis in borderline tumors of the ovary (BTO) according to frozen section. METHODS: All pathology reports with BTO in both frozen and permanent section analyses between 1994 and 2008 at Seoul St. Mary's Hospital were reviewed. Frozen section diagnosis and permanent section histology reports were compared. Logistic regression models were conducted to evaluate the correlation of patient and tumor characteristics with diagnostic accuracy. The clinical outcomes of misdiagnosis were evaluated. RESULTS: Agreement between frozen section diagnosis and permanent histology was observed in 63 of 101 patients (62.4%). Among the 76 patients with frozen section proven BTO, under-diagnosis and over-diagnosis occurred in 8 of 76 (10.5%) and 5 of 76 patients (6.6%), respectively. Mean diameter of under-diagnosed tumor was larger than matched BTO (21.0+/-11.4 vs. 13.7+/-7.1; p=0.021). Tumor size 20 cm was determined as the optimal cut-off for under-diagnosis (50% sensitivity, 87.3% specificity). Among 8 under-diagnosed patients, no patient relapsed. Among 5 over-diagnosed patients, 2 patients < 35 years of age had fertility-preserving surgery. CONCLUSION: Although frozen section diagnosis is an important and reliable tool in the clinical management of patients with ovarian tumors, over-diagnosis and under-diagnosis are relatively frequent in frozen proven BTO. Surgical decision-making for BTO based on frozen section diagnosis should be done carefully, especially in large tumors.

OBJECTIVE: We assessed the prognostic factors and the efficacy of adjuvant therapy and reviewed randomized studies carried out on patients receiving adjuvant therapy with early endometrial carcinoma. METHODS: One hundred and five patients that received primary surgical treatment for stage IB, IC and II endometrial cancer were enrolled in this study. The clinical outcomes were compared among the patients with variable prognostic factors and adjuvant treatments. RESULTS: One hundred and five patients fulfilled the eligibility criteria and 46 patients (43.8%) underwent adjuvant therapy. Disease recurrence occurred in nine patients within a median time of 24 months. Cervical involvement was an independent prognostic factor for the disease-free survival rates. Eight of 16 patients with FIGO stage II disease received adjuvant chemotherapy consisting of cisplatin and etoposide (or cyclophosphamide) or combined chemoradiation. The 5-year disease-free survival rate for these patients was 87.5%, a value significantly higher than for patients that received radiation therapy alone (30%). CONCLUSION: Adjuvant chemotherapy or combination chemo-radiotherapy might be superior to radiation therapy alone in high-risk early endometrial cancer patients.

Metastatic Cancer of Unknown Primary Site (CUP) accounts for approximately 3-5% of all malignant neoplasms. CUP represents a heterogeneous group of metastatic tumors for which no primary site can be detected following a thorough medical history, careful clinical examination, and extensive diagnostic work-up. Several authors have reported poor prognosis of this malignancy, because there is no consensus on diagnostic guidelines and optimal therapy. Historically, chemotherapy has been the cornerstone of treatment for patients with CUP. We experienced a case of inguinal lymph node squamous cell carcinoma of unknown origin, accompanied with carcinoma in situ of the cervix. We report this case with a brief review of the literatures.

PURPOSE: A single center cross sectional retrospective study was performed to compare the outcomes of different peritoneal dialysis(PD) modalities in Korean children. METHODS: Among children dialyzed with PD between the year 2004 and 2007, 35 children had reliable data on PD adequacy after 3 to 15 months of dialysis. Subjects were grouped by their modalities; 17, 13 and 5 children were on continuous ambulatory PD(CAPD), continuous cyclic PD(CCPD) and nightly intermittent PD(NIPD), respectively. Body weight and height, number of patients taking anti-hypertensives and laboratory data including biochemical and hemoglobin levels were compared. Dialysis adequacy including weekly Kt/Vurea, creatinine clearance (Ccr) and daily water removal were also compared. Patients were sub-grouped by their peritoneal permeability characteristics. RESULTS: The percentage of patients taking anti-hypertensives, monthly change in Z-scores of body weight and height and laboratory data did not differ among the groups. Patients on CAPD and CCPD showed similar dialysis adequacies. Weekly dialytic Ccr was significantly lower in the NIPD group compared to the others. But total Ccr was not different when residual renal function was added. Weekly dialytic Ccr by CAPD was significantly higher than that of CCPD in low and low-average transporters. CONCLUSION: We propose that modality can be selected flexibly according to the patients' preferences. And peritoneal permeability characteristics provide valuable information for adjusting PD prescriptions in ultrafiltration failure or in inadequate dialysis. Further study of other clinical performance measures should be performed to clarify the comparable outcomes in different PD modalities.

PURPOSE: The progressive deterioration of renal function in children can impose a serious and lifelong impact on their lives. The ultimate goal in the management of children with chronic kidney disease(CKD) is to prolong survival, to prevent complications, and to promote growth and neurodevelopment. The aim of this study is to investigate the risk factors for the decline of renal function in pediatric CKD patients. METHODS: Data from patients who met the criteria for the Kidney Disease Outcomes Quality Initiative(K/DOQI) CKD stage 2 to 4 between August 1999 and March 2007 were retrospectively analyzed. The estimated glomerular filtration rate(eGFR) was calculated by the Schwartz formula, using serum creatinine levels and height. We calculated the annual eGFR change from the difference between the baseline eGFR and the last eGFR divided by the duration(years) of the follow-up period. We analyzed the association between the annual eGFR change and factors such as age, gender, K/DOQI stage, underlying renal disease, serum calcium, and inorganic phosphorous during the follow-up period. RESULTS: Sixty one children(44 boys & 17 girls) were enrolled. The age at entry was 7.1+/-4.7 years. The annual eGFR change was -1.2+/-11.9 mL/min/1.73m2/year. Our study showed that older age(P=0.005), hypocalcemia(P=0.012), and hyperphosphatemia(P=0.002) were significantly related to more rapid decline in renal function. CONCLUSION: In pediatric CKD, older age, hypocalcemia and hyperphosphatemia are related to more rapid deterioration of renal function.

PURPOSE: Urinary lithiasis is uncommon in children, however, it may lead to chronic renal insufficiency and even end stage renal disease. The etiology of stone formation in children is largely unknown; although the most common causes are known to be associated with congenital anomalies of the genito-urinary(G-U) tract, urinary tract infections(UTI), and metabolic diseases. METHODS: A total of 73 children(male:female=42:31, mean age 6.6+/-5.3 years) presented with urinary lithiasis between Sep. 1998 and Jul. 2007 at Seoul National University Children's Hospital. The medical records were reviewed retrospectively. RESULTS: The most common presenting symptoms were gross hematuria(28/73, 38%) and flank or abdominal pain(23/73, 32%). The stones were located in the upper urinary tract in 48 patients(66%), in the bladder in 18(24%), and in both the bladder and upper urinary tract in 2 (3%). Congenital anomalies of the G-U tract with/without UTI were detected in 30 children (41%), hypercalciuria with/without hypercalcemia in 15(20%), and other metabolic diseases in 8(11%). In 17 patients(23%), no underlying cause of stone formation was detected. The majority of stones were infected stones(24/36, 67%), which were followed by calcium stones(8/36, 22%), uric acid stones(3/36, 8%), and cystine stones(1/36, 3%). Thirty-four patients(46%) underwent surgical procedures and/or extracorporeal shockwave lithotripsy for stone removal, and 13(18%) passed stones spontaneously with/without medical management. Stones recurred in 6 patients(8%): 4 with neurogenic bladder augmented by ileocystoplasty, 1 with cystinuria, and 1 with unknown etiology. CONCLUSION: The common causes of urinary lithiasis in children were congenital anomalies of the G-U tract with/without UTI and metabolic disorders including hypercalciuria/hypercalcemia. For the management of stones, minimally invasive procedures should be chosen on the basis of accompanying symptoms and the composition, locations and etiology of stones.

Malignant neoplasm of the fallopian tube is the rarest of the gynecologic cancers. Vaginal bleeding, vaginal discharge, and pelvic pain are the most common symptoms. Because of these non-specific symptoms, the diagnosis of this least common neoplasm is rarely made before laparotomy. The tumor is typically unilateral and has histologic subtypes, endometrioid and serous adenocarcinoma being the most common subtypes. Surgery, clearly the mainstay of treatment, is also the first approach to diagnosis. The procedure of choice is total abdominal hysterectomy with bilateral salpingo-oopho-rectomy. We had experienced one patient with primary tubal cancer, successfully evaluated with laparoscopy. And then we intend to report the case of the above patient and have a brief discussion about that.

OBJECTIVE: Previous studies were showed that adenoassocited virus (AAV) infection was had negative effects on human papillomavirus (HPV) infection and that the cervical cancer cell growth is inhibited by AAV infection. We detected of AAV 2 and high-risk HPV infection and researched correlation with AAV 2 and HPV in cervical cell. METHODS: Cell of normal cervix (49 persons), infected HPV cervix (45 persons), cervical intraepithelial neoplasm (CIN) I (31 persons), II (20 persons), III (35 persons), and invasive cancer (30 persons) were investigated by PCR using AAV-2 and HPV type 16 and 18 specific primers. RESULTS: AAV 2 was detected in 8 out of 49 normal cervix (16.3%), 2 out of 45 infected HPV cervix (4.4%), 3 out of 31 CIN I (9.7%), 4 out of 20 CIN II (20%), 8 out of 35 CIN III (22.8%), and 3 out of 30 invasive cervical cancer cases (30%). However, HPV 16 was detected in 5 out of 49 normal cervix (10.2%), 20 out of 45 infected HPV cervix (44.4%), 13 out of 31 CIN I (42%), 11 out of 20 CIN II (55%), 19 out of 35 CIN III (54.3%), and 21 out of 30 invasive cervical cancer cases (70%). HPV 18 was detected in 6 out of 49 normal cervix (12.2%), 18 out of 45 infected HPV cervix (40%), 16 out of 31 CIN I (51.6%), 10 out of 20 CIN II (50%), 22 out of 35 CIN III (62.8%), and 13 out of 30 invasive cervical cancer cases (43.3%). CONCLUSION: AAV 2 was detected in normal and infected HPV cervix, CIN (I, II, III) and invasive cervical cancer. As compared to normal, CIN I and CIN II, suggesting significant correlation between AAV 2 and HPV type 16. Further, researches continue to be done relationship to AAV 2 and HPV infection in cervix.

OBJECTIVE: Comparison of protein expressions by two-dimensional gel electrophoresis (2-DE) in normal cervix and squamous cell carcinoma tissues in Korean women. METHODS: Normal cervix and squamous cell carcinoma tissues were solubilized with 2-DE buffer and the first dimension of PROTEAN IEF CELL, isoelectric focusing (IEF), was performed using pH3-10 linear IPG strips of 17 cm. And then running 12% sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and sliver stain. Scanned image was analyzed using PDQuest 2-D softwareTM. Protein spot spectrum was identified by assisted laser desorption/ionization-time of fighting (MALDI-TOF) and the protein mass spectrum identifications were performed by searching protein databases of Swiss-prot/TrEMBL, Mascot and MS-FIT. RESULTS: We found 9 up-regulation proteins (Alpha enolase, Keratin 19 type I, Keratin 20 type I, Keratin 13 type I, beta-actin, Aflatoxin B1 aldehyde reductase 1, Annexin A2, Squamous cell carcinoma antigen 2, unknown), 7 down-reguation proteins (Annexin 1, Myosin regulatory light chain 2, 14-3-3 protein epsilon, Heat shock 27 kDa protein, Hypothetical protein (DKFZP434C1715), Tumor necrosis factor receptor superfamily member 13B, Smoth muscle protein 22-alpha) and 6 up and down-regulation proteins (Tropomyosin 1, Tropomyosin 2, Tropomyosin 3, Serine (or cysteine) proteinase inhibitor, Phosphatidylinositol transfer protein alpha isoform, Src homology 3 domain-containing protein HIP-55) between normal cervix and squamous cell carcinoma cell tissues. CONCLUSION: 2-DE offers total protein expressions between normal cervix and squamous cell carcinoma cell tissues, and searching of differently expressed protein for the diagnostic markers of squamous cell carcinoma tissue.

OBJECTIVE: There is need for more objective diagnostic parameters to identify cervical dysplastic or neoplastic cells. So, we examined the p16(INK4A) expression in the cervical tissues to evaluate the value of p16(INK4A) as a diagnostic parameter. METHODS: We examined the p16(INK4A) expression by immunohistochemical staining in normal cervical tissues (n=3), preneoplastic lesions (n=6), carcinoma in situ (CIS, n=5), and invasive carcinomas (n=5) of the cervix, which were selected randomly by H and E staining from the archives of formalin-fixed and paraffin-embedded tissues and we also examined the status of human papillomavirus (HPV) infection in the same tissues. RESULTS: The positive rates of p16(INK4A) expression was significantly higher in all abnormal cervical tissues including subclinical papillomavirus infection (SPI), dysplasia, CIS, and invasive carcinoma than in normal cervical epithelium (p=0.001). Despite the strong expression of p16(INK4A) in the area of CIS, no expression of p16(INK4A) was observed in the area of normal epithelium in the vicinity of CIS. 11 cases among 19 cases of examined tissue samples were tested for HPV infection. Seven of them showed positivity for HPV DNA. CONCLUSION: We herein demonstrated that p16(INK4A) would be a sensitive and specific marker for the abnormal cervical cells in tissue sections. This approach will help to reduce interobserver variations in the histopathologic interpretation of cervical biopsy specimens.

OBJECTIVE: Adeno-associated virus Rep 78 protein is known to inhibit the promoter site of several onco-genes and viral gene, including the human papillomavirus type 16 E6 transforming genes. In this study, we investigated AAV Rep 78 mediated inhibition of HPV 16 E6 promotor activity. METHODS: pcDNA3.1/V5/His-Topo vector, cloned by AAV mediated Rep 78, is transfected into cervical cancer cell line (Caski). After that, we confirmed HPV16 derived E6 expression and cell growth inhibition. RESULTS: Transfection rate of Rep78 GFP-vector, approximately from 30 to 60 per-cent, is highly expressed at first day. But E6 expression is lower at this day. The growth of CaSki and HeLa cervical cancer cell lines was inhibited by Rep78 (p<0.05). But, the other cervical cancer cells were unaffected by Rep78 transfection. CONCLUSION: In spite of the high Rep78 transfection efficiency and expression rate, we could not show the cervical cancer cell growth inhibition. In our data, long term expression of Rep78 strategy is needed for cervical carcinoma gene therapy using adeno-associated virus vector.

OBJECTIVE: To evaluate the clinical course and pregnancy outcome, according to perforation or no perforation of appendix, in the patients who went through the appendectomy for acute appendicitis during pregnancy. METHODS: We reviewed the chart of paients who went through the appendectomy for acute appendicitis during pregnancy in department of general surgery of the Catholic University of Korea Holy Family Hospital and St. mary's Hospital from January 1994 to May 2004. RESULTS: The incidence rate of acute appendicitis during pregnancy (56.1%) was highest at the 2nd trimester of pregnancy. There was not significant difference in clinical course, subjective symptoms, physical examination results, and the incidence rate of leukocytosis between non-perforated appendicitis (NPAPP) group and perforated appendicits (PAPP) group. The incidence rate of pregnancy loss that was spontaneous abortion and intrauterine fetal death, was 2.9% in NPAPP group and 7.7% in PAPP group, but, there was not significant differnence between two groups. There was not also significant difference in the incidence rate of low birth weight for gestational age. We could find nothing for fetal anomaly. Finally, the term delivery rate was 92.8% and 92.3% in each of the two groups, and patients had no obstetrical and surgical complications. CONCLUSION: In this study, we could find that perforation or no perforation of appendix wieghed with the clinical course, objective symptoms, examination results, and pregnancy outcome of patients. But, we thought that the larger population of perforation group would be needed for more accurate results.

OBJECTIVE: To investigate the infection rate and clinical importance of Mycoplasma hominis (M. hominis) in comparison with Ureaplasma urealyticum (U. urealyticum) in association with preterm labor and preterm rupture of membranes. METHODS: We included 57 women with preterm labor or preterm rupture of membranes admitted at Kangnam St. Mary Hospital, University of Catholic, from March 2002 to April 2003. Mycoscreen kit (Mycoscreen, international microbio, Paris, France) was used for culture of all specimens. Statistical analysis was done by chi-square test (SPSS). RESULTS: The study subjects included 57 women, 15 of premature rupture of membranes (PROM), 16 of preterm prematurely rupture of membranes (PPROM), and 36 of preterm labor. There were 4 women infected by both M. hominis and U. urealyticum, 21 with single infection by M. hominis, 9 with single infection by U. urealyticum, and 23 with negative results from Mycoscreen test. M. hominis infection was noted on 6 of 15 PROM, 5 of 16 PPROM and 2 of 36 preterm labor. And thus, infection by M. hominis is statistically significant in preterm rupture of membranes group in comparison with preterm group (p=0.038). Among 15 cases with leukocytosis on the Gram stain, 2 cases resulted in bacterial growth on the culture. Therefore, leukocytosis on the Gram stain does not show the infection with M. hominis and U. urealyticum. CONCLUSION: Mycoplasma screening in prenatal care provides the predictable information on preterm labor or low birth weight, and could be useful in predicting preterm rupture of membranes. It is thought that further studies are needed with a large number of samples.
