ABSTRACT

Intraperitoneal metastatic hepatocellular carcinoma (HCC) is uncommon. Although rare, it can spontaneously rupture and cause hemoperitoneum similar to primary HCC in the liver. We present a case of intraperitoneal metastatic HCC that had spontaneously ruptured and appeared as an irregularly margined hemorrhagic mass with T1 high and T2 dark signal intensities on magnetic resonance imaging. Ruptured HCC is a life-threatening emergency with high mortality rate. Spontaneously ruptured intraperitoneal metastatic HCC should be considered if a patient with a history of HCC presents with acute abdomen, although rare.

ABSTRACT

An ampulla of Vater neuroendocrine tumor (AOV-NET) is a rare subset of gastroenteropancreatic neuroendocrine tumors (GEP-NETs). Very few studies have been undertaken regarding MRI findings of an AOV-NET. We report on a case of a 59-year-old woman diagnosed with an AOV-NET with liver and lymph node metastasis, with an emphasis on the MRI findings. This case shows rare and precious typical MRI findings of an AOV-NET. The MRI visualized the AOV-NET very well and is helpful for the differentiation of an AOV-NET from other tumors in the ampullary area as well as with treatment planning.

ABSTRACT

Pancreatic lymphoepithelial cysts (LECs) are rare pancreatic cysts with squamous epithelial lining surrounded by dense lymphoid tissue. A preoperative diagnosis of LECs is difficult due to imaging diversity and inadequate documentation because of their rarity. We present a case of surgically confirmed pancreatic LEC with magnetic resonance imaging (MRI) findings as heterogeneous signal intensity on T2-weighted images with multiple septa-like structures, slightly hypo-signal intensity on T1-weighted images, and thin-wall enhancement on dynamic contrast images. LECs are benign lesions without any malignant potential. Therefore, the inclusion of LEC in the differential diagnosis of cystic pancreatic lesions may reduce unnecessary surgical procedures.

ABSTRACT

PURPOSE: The purpose of this study was to investigate the knowledge and practice of patient-controlled analgesia use and management (PCA-UM) among nurses. METHODS: Data were collected from 182 nurses employed by four general hospitals having more than 300 beds in Daejeon. The data were collected using self-report questionnaires from November 4 to November 20, 2015. Collected data were analyzed using descriptive statistics, t-test, and ANOVA. RESULTS: The average nurses' knowledge about PCA-UM was 14.8 points out of 20. PCA-UM knowledge was significantly higher for nurses with experience in PCA education (t=3.55, p < .001). Most participants (91.2%) wanted to get PCA training, 86.8% of them provided PCA education to patients after surgery. Approximately 62% of participants regularly evaluated the level of consciousness of patients with PCA. CONCLUSION: Findings indicate that the knowledge and practice of PCA-UM among nurses were insufficient to provide safe and effective pain management to postoperative patients with PCA. Therefore, it is concluded that it is necessary to develop standardized PCA education programs for nurses to provide safe and effective pain management to postoperative patients with PCA.

ABSTRACT

PURPOSE: We aimed to investigate the triage results and the degree of agreement between prehospital and hospital stages of pediatric patients who visited the emergency department (ED) via emergency medical service providers (EMSP) in comparison with adult patients. METHODS: We retrospectively reviewed 8,152 pediatric patients who visited a regional emergency medical center ED via EMSP from January 2015 to December 2015. Pediatric patients were defined as younger than 15 years according to the Korean Triage and Acuity Scale (KTAS). Given the difference of the triage tools of the prehospital (EMSP) and hospital (KTAS) stages, we performed the re-triage into “critical” and “non-critical” Comparisons of characteristics between pediatric and adult patients were made using chi-square tests. The degree of agreement between the tools was analyzed using κ analysis. RESULTS: Of 8,152 patients, 654 (8.0%) were pediatric patients. Direct medical control was more frequently performed to adult patients (P < 0.001). Critical patients were more common among adults (12.2% by KTAS, 24.8% by EMSP) than children (3.5% by KTAS, 14.1% by EMSP). The κ value of pediatric patients was lower than that of adult patients (0.09 [poor]; 95% confidence interval [CI], 0.01–0.18 vs. 0.38 [fair]; 95% CI, 0.35–0.40). CONCLUSIONS: Pediatric patients transferred by EMSP showed lower severity and degree of agreements of the triage results between prehospital and hospital stages than adult patients. It is necessary to pay particular attention to pediatric triage in a pre-hospital setting.

ABSTRACT

BACKGROUND/OBJECTIVES: Colitis is a serious health problem, and chronic obesity is associated with the progression of colitis. The aim of this study was to determine the effects of natural raw meal (NRM) on high-fat diet (HFD, 45%) and dextran sulfate sodium (DSS, 2% w/v)-induced colitis in C57BL/6J mice. MATERIALS/METHODS: Body weight, colon length, and colon weight-to-length ratio, were measured directly. Serum levels of obesity-related biomarkers, triglyceride (TG), total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL), insulin, leptin, and adiponectin were determined using commercial kits. Serum levels of pro-inflammatory cytokines including tumor necrosis factor-alpha (TNF-alpha), interleukin (IL)-1beta, and IL-6 were detected using a commercial ELISA kit. Histological study was performed using a hematoxylin and eosin (H&E) staining assay. Colonic mRNA expressions of TNF-alpha, IL-1beta, IL-6, inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2) were determined by RT-PCR assay. RESULTS: Body weight and obesity-related biomarkers (TG, TC, LDL, HDL, insulin, leptin, and adiponectin) were regulated and obesity was prevented in NRM treated mice. NRM significantly suppressed colon shortening and reduced colon weight-to-length ratio in HFD+DSS induced colitis in C57BL/6J mice (P < 0.05). Histological observations suggested that NRM reduced edema, mucosal damage, and the loss of crypts induced by HFD and DSS. In addition, NRM decreased the serum levels of pro-inflammatory cytokines, TNF-alpha, IL-1beta, and IL-6 and inhibited the mRNA expressions of these cytokines, and iNOS and COX-2 in colon mucosa (P < 0.05). CONCLUSION: The results suggest that NRM has an anti-inflammatory effect against HFD and DSS-induced colitis in mice, and that these effects are due to the amelioration of HFD and/or DSS-induced inflammatory reactions.

ABSTRACT

OBJECTIVE: 60-year old Korean population has particular life experiences such as Korean War. With this life experience, we aimed to examine the moderating role of social support on the relationship between adverse life events and depressive symptoms in later life. METHODS: The total respondents were 639 people who were 60-year old dwelling in Yangpyung, Gyeonggi Province, South Korea. One to one interviews were conducted by experienced research assistants. RESULTS: Examining depression, 14.7% of total population showed 15 or higher geriatric depression scale-shortform-Korea score. 70% did report stressful life events as many as 13. Also, 31.6% of total participants were isolated or at high risk of isolation. Using hierarchical multiple regression models, the results showed that social support moderated the influence of the exposure to stressful life events on depression (R2=0.124, beta=-0.118, p<0.01). The moderating effect was greater in male (R2=0.118, beta=-1.36, p<0.01) than that of female (R2=0.113, beta=-0.115, p<0.01), which is apposite to our hypothesis. CONCLUSION: This finding suggests that social support play critical roles in the stress-outcome relationship among 60-years old population like it was suggested. Since most stressful events are inevitable, it is important to build sufficient social support networks.

ABSTRACT

Superior vena cava syndrome (SVCS) is usually caused by extrinsic compression or invasion of the superior vena cava (SVC) by malignant tumors involving mediastinal structures. Although thymomas are well-known causes of SVCS, cases of SVCS caused by malignant thymomas protruding into adjacent vessels draining the SVC with thrombosis have been very rarely reported worldwide. We experienced a 39-year-old female patient with SVCS that developed after the direct invasion of the left brachiocephalic vein (LBCV) and SVC by an anterior mediastinal mass with a high maximum standardized uptake value on the chest computed tomography (CT) and positron emission tomography-CT. Based on these results, she underwent en bloc resection of the tumor, including removal of the involved vessels, and was eventually diagnosed as having a type B2 thymoma permeating into the LBCV and SVC. We present this case as a very rare form of SVCS caused by an invasive thymoma.

ABSTRACT

The incidence of type 2 diabetes is rising rapidly because of an increase in the incidence of being overweight and obesity. Identification of genetic determinants for complex diseases, such as type 2 diabetes, may provide insight into disease pathogenesis. The aim of the study was to investigate the shared genetic factors that predispose individuals to being overweight and developing type 2 diabetes. We conducted genome-wide linkage analyses for type 2 diabetes in 386 affected individuals (269 sibpairs) from 171 Korean families and association analyses with single-nucleotide polymorphisms of candidate genes within linkage regions to identify genetic variants that predispose individuals to being overweight and developing type 2 diabetes. Through fine-mapping analysis of chromosome 4q34-35, we detected a locus potentially linked (nonparametric linkage 2.81, logarithm of odds 2.27, P=6 x 10-4) to type 2 diabetes in overweight or obese individuals (body mass index, BMI> or =23 kg m-2). Multiple regression analysis with type 2 diabetes-related phenotypes revealed a significant association (false discovery rate (FDR) P=0.006 for rs13144140; FDR P=0.002 for rs6830266) between GPM6A (rs13144140) and BMI and waist-hip ratio, and between NEIL3 (rs6830266) and insulin level from 1314 normal individuals. Our systematic search of genome-wide linkage and association studies, demonstrate that a linkage peak for type 2 diabetes on chromosome 4q34-35 contains two type 2 diabetes-related genes, GPM6A and NEIL3.

ABSTRACT

OBJECTIVE: To investigate the effect of the dimethyl sulfoxide (DMSO) and EFS-40 during vitrification on the expression of angiogenic factors in vitrified mouse ovarian tissue. METHODS: The ovarian tissues were obtained from 5 or 6 weeks aged ICR mouse. Ovarian tissues were divided into four groups: ovarian tissue without cryopreservation (control, group I), ovarian tissue vitrified with 15% DMSO (group II), ovarian tissue vitrified with EFS-40 (group III), and ovarian tissue slowly frozen with 10% DMSO (group IV). Thawing was carried out at room temperature. Levels of messenger RNA (mRNA) and protein for vascular endothelial growth factor-A (VEGF-A) and angiopoietin-2 (Angpt-2) were checked in ovarian tissues of four groups recovered on day 7 after cryopreservation. Reverse transcription-polymerase chain reaction and Western blot analysis were used to identify the levels of angiogenic factors in mouse ovarian tissues. RESULTS: Levels of mRNA and protein for VEGF-A and Angpt-2 were significantly decreased in cryopreserved group (group II, III and IV) than control group (group I) (P< 0.05). The significant differences of levels of mRNA and protein for VEGF-A and Angpt-2 between cryopreservation methods were observed (P< 0.05). Group III showed highest expression of mRNA and protein for VEFG-A and Angpt-2 than other cryopreservation groups (P< 0.05). CONCLUSION: These findings suggest that EFS-40 is more efficient vitrification solution for preservation of angiogenic factors than 15% DMSO during vitrification of mouse ovarian tissue. Future studies should investigate to improve the vitrification solution for ovarian tissue vitrification.

ABSTRACT

PURPOSE: The purpose of this study is to assess the usefulness of Doppler parameters in transplanted kidney function. MATERIALS AND METHODS: Doppler parameters, including resistive index (RI), pulsatility index (PI), peak systolic velocity (PSV), and end diastolic velocity (EDV) were measured in the interlobar artery of 55 transplant recipients. Patients were grouped according to glomerular filtration rate (GFR): Group A (GFR or = 30 ml / min / 1.73 m2, n = 28). Doppler parameters were compared between groups and correlated with the GFR. RESULTS: GFR (40.1 +/- 26.9) showed a significant negative correlation with RI (0.69 +/- .08) (p = .002, r = -.414). RI (0.72 vs. 0.67), PI (1.42 vs. 1.23), and EDV (10.5 vs. 15.3) differed significantly between groups (p < .05), however, PSV was not (36.9 vs. 47.1). Patients in group A (n = 11) with a lower RI than the mean had significantly lower PSV (31.7 vs. 45.1; p = .027) and EDV (11.1 vs. 16.7; p = .017), compared with such patients in group B (n = 21). CONCLUSIONS: Doppler parameters are useful for evaluation of function of transplanted kidney. Even if the RI is normal, PSV and EDV may be used as hemodynamic indicators.

ABSTRACT

PURPOSE: To assess the safety and usefulness of ultrasonography-guided transthoracic cutting biopsy for lung lesions. MATERIALS AND METHODS: Eighty-eight patients (66 men, 22 women, mean age 59 years) with lung lesions underwent an ultrasonography(USG)-guided transthoracic cutting biopsy. The final diagnosis was based on the findings of surgery and clinical and radiological follow-ups. The histopathologic results and diagnostic accuracy of cutting biopsy were determined. Also, the complication rate was statistically evaluated according to the mass size, number of biopsies, and the presence or absence of pleural effusion. RESULTS: Biopsy specimens were successfully obtained in all patients. 79 of 88 lesions (89.8%) were established by histopathology. The final diagnosis was malignant in 58 and benign in 28. The remaining 2 patients were lost to follow-up. Diagnostic sensitivity for malignant lesions was 89.6% (52/58) and that for benign lesions was 96.4% (27/28). Procedure-related complications occurred in 9 patients (10.2%) including pneumothorax (n = 2) and hemoptysis (n = 7). And there was no significant difference according to mass size, number of biopsies, or presence of pleural effusion. CONCLUSION: USG-guided transthoracic cutting biopsy is a useful and safe method for technically-feasible lung lesions.

ABSTRACT

PURPOSE: The aim of this study was to observe the clinical features of a bezoar-induced small bowel obstruction and to investigate the role of abdominal computed tomography (CT) in establishing the diagnosis. METHODS: We retrospectively reviewed 20 cases of bezoar-induced small bowel obstruction in our hospital from 1996 to 2010. RESULTS: Thirteen patients (65%) had a history of abdominal surgery. Nine patients (45%) were diagnosed with a bezoar before surgery, seven patients were diagnosed by using abdominal CT, and two patients were diagnosed with a small bowel series. Abdominal CT was performed in 15 patients, and the diagnostic accuracy was 47% (7/15). Surgery revealed ten bezoars in the jejunum and 11 in the ileum. Two patients had bezoars found concurrently in the stomach. Spontaneous removal took place in two patients. An enterotomy and bezoar extraction was performed in 15 patients. Fragmentation and milking, a small bowel resection, and a Meckel's diverticulectomy were performed in one patient each. Early operative treatment was possible (P = 0.036) once the bezoar had been diagnosed by using abdominal CT. There tended to be fewer postoperative complications in patients who were diagnosed with a bezoar by using abdominal CT, but the result was not statistically significant (P = 0.712). CONCLUSION: A preoperative diagnosis of bezoar-induced small bowel obstruction by using clinical features was difficult. Increased use of abdominal CT led to a more accurate diagnosis and to earlier surgery for bezoar-induced small bowel obstructions, thereby reducing the rate of complications.

ABSTRACT

BACKGROUND/AIMS: Various strategies to expand the ablation zone have been attempted using hepatic radiofrequency ablation (RFA). The optimal strategy, however, is unknown. We compared hepatic RFA with an internally cooled wet (ICW) electrode and vascular inflow occlusion. METHODS: Eight dogs were assigned to one of three groups: only RFA using an internally cooled electrode (group A), RFA using an ICW electrode (group B), and RFA using an internally cooled electrode with the Pringle maneuver (group C). The ablation zone diameters were measured on the gross specimens, and the volume of the ablation zone was calculated. RESULTS: The ablation zone volume was greatest in group B (1.82+/-1.23 cm3), followed by group C (1.22+/-0.47 cm3), and then group A (0.48+/-0.33 cm3). The volumes for group B were significantly larger than the volumes for group A (p=0.030). There was no significant difference in the volumes between groups A and C (p=0.079) and between groups B and C (p=0.827). CONCLUSIONS: Both the usage of an ICW electrode and hepatic vascular occlusion effectively expanded the ablation zone. The use of an ICW electrode induced a larger ablation zone with easy handling compared with using hepatic vascular occlusion, although this difference was not statistically significant.

ABSTRACT

Hemoptysis in patients with lung cancer is not uncommon and sometimes have dangerous consequences. Hemoptysis has been managed with various treatment options other than surgery and medicine, such as endobronchial tamponade, transcatheter arterial embolization and radiation therapy. However, these methods can sometimes be used only temporarily or are not suitable for a patient's condition. We present a case in which uncontrollable hemoptysis caused by central lung cancer was successfully treated by inserting a covered self-expanding bronchial stent. The patient could be extubated and was able to undergo further palliative therapy. No recurrent episodes of hemoptysis occurred for the following three months. As our case, airway stenting is a considerable option for the tamponade of a bleeding lesion that cannot be successfully managed with other treatment methods and could be used to preserve airway patency in a select group of patients.

ABSTRACT

Ectopic pregnancy is a potentially life-threatening condition. Detection of ectopic pregnancy on CT images is rare. In this case, we describe the CT findings of interstitial pregnancy both before and after rupture. If CT images demonstrate the presence of a strong enhancing ring-like mass in the pelvis, ectopic pregnancy should be considered.

ABSTRACT

Acalculous hemorrhagic cholecystitis is a rare complication of acute cholecystitis and is associated with a high mortality rate. We present a case of acalculous hemorrhagic cholecystitis with hematoma in the gallbladder lumen, which was diagnosed using magnetic resonance imaging (MRI). The T1- & T2-weighted MRI revealed gallbladder distension with a hypointense intraluminal hematoma. The excellent tissue contrast provided by MRI is useful for detecting hematomas in the cases of hemorrhagic cholecystitis.

ABSTRACT

A 57-year old man who was admitted to an emergency room of a tertiary hospital with hemoptysis developed malarial fever 19 days later and then died from severe falciparum malaria 2 days later. He had not traveled outside of Korea for over 30 years. Through intensive interviews and epidemiological surveys, we found that a foreign patient with a recent history of travel to Africa was transferred to the same hospital with severe falciparum malaria. We confirmed through molecular genotyping of the MSP-1 gene that Plasmodium falciparum genotypes of the 2 patients were identical. It is suggested that a breach of standard infection control precautions resulted in this P. falciparum transmission between 2 patients in a hospital environment. This is the first report of a nosocomial transmission of falciparum malaria in Korea.

ABSTRACT

PURPOSE: To evaluate the usefulness and safety of the placement of an implantable chemoport via external jugular vein as a primary route for chemotherapy. MATERIALS AND METHODS: Between January 2006 and June 2007, a total of 108 implantable chemoports were placed on 325 patients for chemotherapy via the external jugular vein as a primary route. We placed a 9.6 F single lumen chemoport using a surgical procedure (n=89) and an interventional procedure (n=19), and evaluated the duration of catheterization days and treatment complications. RESULTS: An implantable chemoport was successfully installed in all cases. Furthermore, the duration of catheterization ranged from 2 to 461 days (mean: 187 days, total catheter days: 21,994). In addition, a total of 85 chemoports were removed due to complications (n=7) and termination of chemotherapy (n=78). A transient pulmonary air embolism occurring during a procedure was observed in one case. No pneumothorax or catheter malpositions were observed in the study subjects. Two chemoports were removed two days after implantation due to persistent tachycardia. In addition, five late complications occurred, which resulted in catheter occlusion (3 cases) (3%, 0.14/1000 catheter day) and infection in (2 cases) (2%, 0.09/1000 Catheter days). Lastly, no symptoms were attributed to a central vein thrombosis. CONCLUSION: The results of this study suggest that the implantation of chemoports via the external jugular vein is a safe procedure. Moreover, the selection of the external jugular vein as a primary route is useful in determining chemoport insertion locations.
