Résumé

Hepatitis C virus (HCV) is a major cause of chronic hepatitis, liver cirrhosis and hepatocellular carcinoma. HCV core protein has been shown to modulate various cellular signaling pathways including the nuclear factor κB (NF-κB) pathway which is associated with inflammation, cell proliferation and apoptosis. However, there have been conflicting reports about the effect of HCV core protein on NF-κB pathway, and the mechanism by which the core protein affects NF-κB activity remains nuclear. In this study, the functional interaction of HCV core protein and IκB kinase γ (IKKγ) was investigated using the expression plasmids of core and the components of IKK complex. The data revealed that HCV core protein activates NF-κB. Also, HCV core protein up-regulated the phosphorylation and degradation of IκBα. The activating effect of HCV core protein on NF-κB was synergistically elevated by IKKγ. It was noticed that the N-terminal IKKβ binding site, C-terminal leucine zipper, and zinc finger domains of IKKγ are not necessary for its synergistic effect. HCV core protein and IKKγ appeared to activate NF-κB by up-regulating the IKKβ activity resulting in the degradation of IκBα. As expected, HCV core protein induced the expression of NF-κB-targeted pro-inflammatory genes such as iNOS, IL-1β and IL-6 in the transcription level. These results suggest that HCV core protein induces NF-κB through the interaction with IKKγ and may play a critical role in the development of inflammation and related liver diseases.

Résumé

PURPOSE: The purpose of this study was to investigate the changes on alpine skiers' body composition, anaerobic power, isokinetic knee strength and muscle balance ratio (hamstring to quadriceps [HQ] ratio) before and after winter season. METHODS: The subjects of this study was 22 elite alpine skier, aged 16–20 years. Participants were divided into two groups (male, 12; female, 10). The study conducts a periodization training program in the winter season for 4 months. The data processing of this study was analyzed by paired t-test, using SPSS 21.0 statistics program. RESULTS: There was significance on fat free mass in male group (p < 0.05); there was significance on anaerobic power and average power in female group (p < 0.01), and fatigue index significantly increased in male group (p < 0.05). There was significance on extension power of male group and flexion power of female group in 30°/sec. There was significance on extension power of both groups in 180°/sec (p < 0.05). There was significant increase on flexion power of male group in 240°/sec (p < 0.01). There was significant increase on H/Q% of female right side in 30°/sec (p < 0.01). There was significance on right side of both groups in 180°/sec (p < 0.05). There were significances on right and left side of both groups in 240°/sec (male, p < 0.01; female, p < 0.05). CONCLUSION: Therefore, this study suggests that the periodization training should be important to maintain and to develop seasonal condition of alpine skiers.

Résumé

PURPOSE: This study evaluated the benefits of adjuvant chemotherapy on elderly patients with advanced gastric cancer (AGC) using meta-analysis of well-designed randomized controlled clinical studies. MATERIALS AND METHODS: PubMed, Embase, and Cochrane were searched to retrieve clinical studies evaluating the benefits of adjuvant chemotherapy in the elderly with AGC. Hazards ratios (HRs) with 95% confidence intervals (CIs) were pooled across studies using a fixed-effects model. RESULTS: Two studies were included in this meta-analysis to estimate HR for the overall survival (OS), and relapse-free survival (RFS) between adjuvant chemotherapy and surgery in elderly and non-elderly patients. HR for OS in the elderly and non-elderly was 0.745 (95% CI, 0.552 to 1.006, p=0.055) and 0.636 (95% CI, 0.522 to 0.776; p < 0.001), respectively, which showed no heterogeneity regarding HR between the two groups (p(interaction)=0.389). HR for RFS in the elderly and non-elderly was 0.613 (95% CI, 0.466 to 0.806; p < 0.001) and 0.633 (95% CI, 0.533 to 0.753; p < 0.001), respectively (p(interaction)=0.846). CONCLUSION: Meta-analysis suggests that the benefit of adjuvant chemotherapy to the elderly is not big enough to reach statistical significance while the HR for OS is less than 1 (0.745) and no heterogeneity are observed regarding the HR between the elderly and non-elderly patients.

Résumé

PURPOSE: The purpose of this study is to investigate differences in organ-specific cancer incidence according to the region and population size in Korea. MATERIALS AND METHODS: We reviewed the data of the cancer registration program of Gyeongnam Regional Cancer Center between 2008 and 2011. Age-standardized rates of cancer incidence were analyzed according to population size of the region and administrative zone. RESULTS: Incidence of thyroid cancer has been increasing rapidly in both urban and rural areas. However, the thyroid cancer incidence was much lower in rural areas than in urban areas and megalopolis such as Seoul. Gastric cancer was relatively more common in rural areas, in megalopolis near the sea (Ulsan, Busan, and Incheon), and other southern provinces (Chungcheongnam-do, Gyeongsangbuk-do, and Gyeongsangnam-do). A detailed analysis in Gyeongsangnam-do revealed that rural areas have relatively low incidence of thyroid and colorectal cancer, and relatively high incidence of gastric and lung cancer compared to urban areas. CONCLUSION: This study suggests that there are some differences in cancer incidence by population size. Thyroid and colorectal cancer incidence was increasing, and gastric and lung cancer was slightly decreasing in urban areas, whereas gastric and lung cancer incidence still remains high in rural areas.

Résumé

PURPOSE: Advanced cancer may accompany cold sweat as paraneoplastic symptom. Few studies have been performed on the efficacy of non-steroid anti-inflammatory drug (NSAID) in advanced cancer patients who sweated without fever. METHODS: To select study participants, medical records were retrospectively reviewed for patients who satisfied the following criteria: 1) incurable, advanced solid cancer; 2) Cold sweating of 4 or higher on the numeric rating scale (NRS) 4; 3) No evidence of infection or hypoglycemia; 4) No newly started opioid or anti-hormonal agents within one month; 5) NSAID prescription for the management of cold sweating and 6) Documented NRS information before and after NSAID administration. RESULTS: A total of 13 patients were selected after excluding four patients due to lack of NRS information or fever. The mean age was 59 years old (range: 50~71), and nine patients (69%) were male. Bile duct cancer was the most common primary tumor followed by pancreatic cancer, gastric cancer and prostate cancer. The mean NRS of cold sweating dropped from baseline 6.5 (min-max: 4~10) to 1.9 at the follow-up assessment (min-max: 0~5). The mean follow-up period was 9.1 days (range: 2~30 days) from NSAID treatment to assessment. CONCLUSION: NSAID was effective medication for management of sweating without fever in patients with advanced cancer.

Résumé

Spinal cord injury (SCI) may lead to urinary system disturbances. Patients with SCI usually have neurogenic bladder, and treatment optionss for this condition include clean intermittent catheterization and a permanent indwelling urethral or suprapubic catheter. Complications of catheterization include urinary tract infection, calculi, urinary tract injury, bladder contraction, bladder spasm, renal dysfunction, bladder cancer, and so forth. To the best of our knowledge, ureteral rupture is an unusual complication of catheterization, and ureteral rupture has been rarely reported in SCI patients. Therefore, here we report a case of ureteral rupture caused by a suprapubic catheter used for the treatment of neurogenic bladder with vesicoureteral reflux in a male patient with SCI. Due to SCI with neurogenic bladder, ureteral size can be reduced and the suprapubic catheter tip can easily migrate to the distal ureteral orifice. Thus, careful attention is required when a catheter is inserted into the bladder in patients with SCI.

Résumé

BACKGROUNDS: Patient counseling has been forced since June. 19, 2014. Prior to this, there was no study to try to standardize medication counseling to improve quality. PURPOSE: This study was to investigate satisfaction level and comprehension level between the pharmacist group and the patient group about standardized medication counseling sheet. METHODS: Questionnaires to assess standardized patient counseling sheet were posted at online survey software (Qualtrics) to pharmacists who worked at community pharmacy and patients who had visited community pharmacy before. RESULTS: Three hundred thirty five patients and three hundred nineteen pharmacists were responded to the questionnaire (Response rate: 72.9%). More than half of each group were satisfied with standardized medication counseling sheets 'for the general public', 'for the pregnant women and nursing mothers', 'for the chronic patient', and 'for the aged' and patient group were more satisfied than pharmacist group. Similarly, more than half of each group comprehended with the medication counseling sheets 'for the general public', 'for the pregnant women and nursing mothers', 'for the chronic patient', and 'for the aged'. Patient group tended to expect longer patient counseling time per one drug than pharmacist group. Also, the majority of both groups wanted to provide standardized medication counseling sheets constantly and extend for all drugs. CONCLUSION: Both groups were satisfied and comprehended standardized medication counseling sheets, and agreed to expand standardized medication counseling sheets to all drugs. So, it is necessary to build the standardized medication counseling of all drugs.

Résumé

BACKGROUND/AIMS: The diagnostic yield of fecal leukocyte and stool cultures is unsatisfactory in patients with acute diarrhea. This study was performed to evaluate the clinical significance of the fecal lactoferrin test and fecal multiplex polymerase chain reaction (PCR) in patients with acute diarrhea. METHODS: Clinical parameters and laboratory findings, including fecal leukocytes, fecal lactoferrin, stool cultures and stool multiplex PCR for bacteria and viruses, were evaluated prospectively for patients who were hospitalized due to acute diarrhea. RESULTS: A total of 54 patients were included (male, 23; median age, 42.5 years). Fecal leukocytes and fecal lactoferrin were positive in 33 (61.1%) and 14 (25.4%) patients, respectively. Among the 31 patients who were available for fecal pathogen evaluation, fecal multiplex PCR detected bacterial pathogens in 21 patients, whereas conventional stool cultures were positive in only one patient (67.7% vs 3.2%, p=0.000). Positive fecal lactoferrin was associated with presence of moderate to severe dehydration and detection of bacterial pathogens by multiplex PCR (21.4% vs 2.5%, p=0.049; 100% vs 56.5%, p=0.032, respectively). CONCLUSIONS: Fecal lactoferrin is a useful marker for more severe dehydration and bacterial etiology in patients with acute diarrhea. Fecal multiplex PCR can detect more causative organisms than conventional stool cultures in patients with acute diarrhea.

Résumé

Terson syndrome is a vitreous hemorrhage associated with subarachnoid hemorrhage. This can be caused by spontaneous, aneurysmal rupture or traumatic subarachnoid hemorrhage, but never has been reported as a consequence of hemorrhage due to thrombolysis and thrombectomy treatments of acute ischemic stroke patient. A 48-year-old man presented with left sided weakness was diagnosed as cerebral infarction on right middle cerebral artery territory due to complete occlusion of right distal internal carotid, middle cerebral, and anterior cerebral artery. He underwent thrombolysis and mechanical thrombectomy, and subarachnoid hemorrhage developed. Later, visual disturbance on right eye occurred so he was consulted to ophthalmology. Vitreous hemorrhage was found and surgery was recommended after two weeks of observation. After pars planar vitrectomy, visual acuity improved, along with functional ability. Therefore, possibilities of Terson syndrome in patients with subarachnoid hemorrhage have to be kept in mind to improve not only visual acuity but also rehabilitation outcome.

Résumé

Hypereosinophilic syndrome (HES) is defined as peripheral eosinophilia, organ involvement of eosinophils and exclusion of other disorders or dysfunction. HES is subclassified as myeloproliferative variant, T-lymphocytic, overlap, idiopathic, familial and associated type according to the new classification using molecular and immunologic markers. HES presenting with gastrointestinal symptoms is very rare but characterized by peripheral eosinophilia, eosinophilic infiltration of the gastrointestinal tract with other organs such as liver and bone marrow. We report a rare case of idiopathic HES in 18-year-old adolescent who presented with gastrointestinal symptoms including abdominal pain, diarrhea and ascites which resolved rapidly with corticosteroid therapy. HES should be included in the differential diagnosis of abdominal pain and ascites in children and adolescents.

Résumé

BACKGROUND/AIMS: Depth of invasion is one of the most important factors for establishing treatment strategy for colorectal tumors. METHODS: Three blinded experts reviewed electronic photos and video clips of 33 early colorectal cancer-like lesions. They estimated the depth of invasion based on conventional white light endoscopy (CWE), magnifying chromoendoscopy (MCE), and magnifying narrow band imaging endoscopy (MNE). RESULTS: The lesions included nine mucosal low-grade neoplasias, 16 mucosal high grade neoplasias, and eight carcinomas with invasion to the submucosal layer or beyond. The diagnostic accuracy for submucosal invasion by CWE ranged from 67% to 82%, while those by MCE and MNE ranged from 85% to 88% and 85% to 88%, respectively. The diagnostic accuracy significantly differed between CWE and MCE (p=0.034) and between CWE and MNE (p=0.039). The kappa values for CWE, MCE, and MNE among the endoscopists were 0.564, 0.673, and 0.673, respectively. CONCLUSIONS: The estimation of submucosal invasion for early colorectal cancer-like lesions based on MCE or MNE is more accurate than CWE. MCE and MNE were demonstrated to have substantial agreement for predicting submucosal invasion.

Résumé

Gastrointestinal leakage is one of the most serious post surgical complications and is a major source of mortality and morbidity. The insertion of a covered self-expandable metal stent could be a treatment option in selected cases. However, it is unclear how long the stent should be retained to achieve complete sealing, and membrane-covered stents have the problem of a high migration rate. We observed four cases of postsurgical leakage following the primary closure of a duodenal perforation, esophagojejunostomy, and esophagogastrostomy, each of which was successfully managed by the temporary placement of covered stents. In all cases, the optimal time of stent removal could be estimated by the markedly decreased amount of drainage, the lack of leakage observed on radiocontrast images, and the endoscopic findings. In this case series, all of the stents could be removed within 7 weeks. For those cases with a high risk of migration, stents with temporary fixations to earlobes and/or partially uncovered proximal flanges were used. These results suggest that the application of a covered stent could be a treatment option for various gastrointestinal leaks after surgery, particularly when the defect cannot be sealed by conservative care and the leakage has good external drainage.

Résumé

BACKGROUND/AIMS: Endoscopic management of upper gastrointestinal obstruction is safe and feasible. However, its technical and clinical success rate is about 90%, which is primarily due to inability to pass a guide-wire through the stricture. The aim of this study was to evaluate the usefulness of an ultrathin endoscope for correct placement of guide wire to avoid technical failure in upper gastrointestinal obstruction. METHODS: Retrospective assessment of ultrathin endoscope to traverse the stenosis of the upper gastrointestinal tract in technically difficult cases was performed. Technical and clinical success rates and immediate complications were analyzed. RESULTS: Nine cases were included in this study (eight cases of stent insertion and one case of balloon dilatation). Technical success was achieved in all of the patients (100%) and oral feeding was feasible in all of the cases (100%). Immediate complications, such as migration, perforation, and hemorrhage, did not develop in any of the cases. CONCLUSIONS: Ultrathin endoscope-assisted method for upper gastrointestinal obstruction is potentially safe and useful to avoid technical failure.

Résumé

Mucoceles are common benign cystic lesions of the oral cavity that develop following extravasation or retention of mucous material from the major or minor salivary glands. Mucoceles are usually located in the lower lip (60 to 70% of cases), and the floor of the mouth is only involved in 6 to 15% of cases. Submandibular gland mucocele is extremely rare but should be considered in the differential diagnosis of swelling at the submandibular triangle in young children. We present the rare case of a 16-month-old child who was diagnosed with bilateral submandibular gland mucocele, presenting as serial swellings in both submandibular regions. We removed the cystic mass with the submandibular and sublingual glands to prevent recurrence.

Résumé

PURPOSE: The study assessed the effect of exogenous surfactant on oxygen and ventilator requirements and long-term prognosis of neonates with respiratory deterioration due to pulmonary hemorrhage. METHODS: From March 2007 to March 2011, neonates with respiratory deterioration due to pulmonary hemorrhage in Saint Mary's Hospital were identified from the database. Among 20 patients with pulmonary hemorrhage, 10 patients received surfactant therapy and the other 10 did not. We compared outcomes of these two groups. The primary outcome was changes in respiratory status following surfactant therapy, as reflected by oxygen index (OI), fractional inspired oxygen (FiO2) and mean airway pressure (MAP). Secondary outcomes were the duration of ventilation, nasal continuous positive airway pressure (NCPAP), oxygen inhalation days, progression to severe bronchopulmonary dysplasia or death, and retinopathy of prematurity, which required laser therapy. RESULTS: Surfactant treatment group had higher FiO2, MAP, and OI than the non-treatment group during pulmonary hemorrhage. But, there were no differences in FiO2, MAP, and OI after 2 hours of pulmonary hemorrhage between the two groups. There were no significant side effects during surfactant treatment in the surfactant treatment group. Surfactant treatment group had fewer ventilator days, NCPAP days (P<0.05) and a tendency towards shorter oxygen days than the non-treatment group (P=0.09). Also, the surfactant treatment group had less severe bronchopulmonary dysplasia (BPD) or death than the non-treatment group (10% vs. 70%, P<0.05). CONCLUSION: Exogenous surfactant appears to be a useful adjunctive therapy with neonates of severe respiratory deterioration due to pulmonary hemorrhage. Also, exogenous surfactant treatment dose not seen to be associated with any significant side effects during the therapy.

Résumé

PURPOSE: The current study was aimed to investigate the transformational experience of a female student nurse living with type 1 diabetes. METHODS: A case study of a 24-year-old diabetes patient was conducted, with interviews concerning the evolving process she had lived through during the period from her later high school years to her graduation from nursing college. RESULTS: Followings were identified as 5-transformation process: With her diabetes-related limitation, the participant experienced 'conflict involving choosing a college and major'. The participant tried to be in charge of managing her diabetes and stepped forward to 'adaptation to college life as a new environment', and she learned more about the process of 'evolving awareness of caring' and developed herself further through the process of 'integration of the nurse identity into self-identity', and finally through the process of 'progression and preparation for getting a job' she achieved her goals, being positive about the future. CONCLUSIONS: The results of the study can provide individuals with diabetes a way of self-management and help the patients and their families in diabetes education. Further research will be needed to refine the results of this study and to learn more about the experiences of patients with type I diabetes in college years.

Résumé

PURPOSE: Cyanate, known as one of the uremic toxins and derived spontaneously from urea, has several effects on the biologic substances including erythropoietin, antioxidant and ceruloplasmin. To find out the protective materials from the hazardous effect of cyanate in osteoblast, we added twenty amino acids, albumin globulin and hemoglobin in the culture media containing osteoblastic cells with cyanate. METHODS: Osteoblastic ROS 17/2.8 cells, exposed to various concentrations of sodium cyanate, were used to analyze for the cytotoxicity. The cyanate-induced cytotoxicity was assessed by the methylthiazolyldiphenyl-tetrazolium bromide (MTT) assay by measuring the absorbance of the reaction solution at 570 nm. Viability of the treated cells was expressed as A570 of sample/A570 of control. The degree of the carbamylation was measured using trinitrobenzenesulphonic acid. The degree of the carbamylation in amino acid was about 50% in average. RESULTS: The degree of the carbamylation in albumin was increased depending on the incubation time with cyanate and the concentration of the cyanate. The degree of the carbamylation in globulin and hemoglobin was nearly zero. Asp, Glu, Leu, Trp and Tyr among the twenty amino acids revealed the protective effect against the damage induced by cyanate. And only albumin among the three proteins revealed the protective effect. CONCLUSION: On the basis of these results, Asp, Glu, Leu, Trp, Tyr and albumin are useful tools for the protection against damages by cyanate carbamylation.

Résumé

An 82-year-old man presented at our clinic with a 3-year history of an of erythematous, verrucous plaque on his right inguinal area. Histopathologically, severe acanthosis, dysregulated hyperplasia of the epidermis, atypical hyperchromatic cells, and many clear cells were observed. In addition, invasion of tumor cells into the dermis were noted. On the suspicion of metastasis to the right inguinal lymph nodes based on the radiologic findings, lymph node dissection was performed. The dissected lymph node showed the same pathologic findings as the skin lesion. Immunohistochemical staining showed a positive reaction to cytokeratin 116 and epithelial membrane antigen (EMA). Based on these findings, clear cell squamous cell carcinoma with metastasis was diagnosed. We report a case of clear cell squamous cell carcinoma, which probably developed from underlying Bowen's disease.
