Purpose: This study compared clinical outcomes and complications in patients with humeral shaft fractures treated using two methods of fixation by plating. Methods: Minimally invasive plate osteosynthesis (MIPO, n= 29) was prospectively performed from around the middle of the study period, while open reduction and plate osteosynthesis (ORPO, n= 30) had been the original standard method. Locking compression plate was used in these two groups. Major characteristics of the two groups were similar in terms of fracture type, fracture location, age, associated injuries and numbers of open fractures. Results: Primary union was achieved in 28 of 29 in the MIPO and in 27 of 30 in the ORPO. Mean time to union was similar in the two groups. Mean operation time in the MIPO (110. min) was shorter than in the ORPO (169. min) (P< 0.05). Bone grafting was performed in five patients of in the ORPO, but in no patient in the MIPO (P< 0.0001). There was one case of deep infection in the ORPO. Functional outcome was satisfactory in both groups. Conclusions: Minimally invasive plate osteosynthesis may achieve comparable results with the open plate osteosynthesis method in simple as well as complex fractures of humeral shaft. Although MIPO potentially has the radiation hazard, it may reduce the perioperative complications with a shortened operation time. Level of evidence: Level III.

Purpose: To investigate the usefulness of the combined categorical reporting system of ultrasonography (US) and cytology results for thyroid nodules to suggest indications of repeat US-guided fine needle aspiration cytology (FNAC). Materials and Methods: Institutional review board approval was obtained, and the requirement for informed consent was waived for this retrospective study. From June 2001 to December 2009, 1084 patients (978 women, 106 men) who underwent repeat US-guided FNAC of thyroid nodules were included. FNAC results were reported by using the Bethesda system for reporting thyroid cytopathologic findings and five thyroid US categories (category US 1, benign; US 2, probably benign; US 3, indeterminate; US 4, probably malignant; US 5, malignant). The relative risk ratios were evaluated in each separate FNAC and combined initial category by means of Cox proportional risk model. Results: Eighty-one of 1084 (7.5%) patients had malignancy over a mean follow-up time of 20.8 months (range, 3-98 months). Initial FNAC category of atypia of undetermined significance (relative risk ratio, 9.677) and US categories of US 3 (28.76), US 4 (142.0), and US 5 (411.6) had high relative risk ratios for malignancy (P < .05). Combined categories of benign cytology findings with US 3-5, nondiagnostic cytology findings with US 3-5, and atypia of undermined significance with any US categorization had high relative risk ratios of 104.80 (95% confidence interval: 53.328, 205.966). Conclusion: The combination of the categorical reporting systems between cytology and US results could be useful to suggest indications of repeat US-guided FNAC. © RSNA, 2012.

Background: Femoral fractures in adolescents usually need operative treatment, but the optimal method is unclear. The purpose of this study is to compare intramedullary nailing (IN) and submuscular plating (SP) in adolescent femoral fractures. Materials and methods: We performed the prospective, comparison study of IN and SP in adolescent femoral shaft fractures at a mean age of 13.9 years (11-17.4). Twenty-two cases of IN and 23 cases of SP were followed for a minimum of 1 year. We compared radiological and clinical results, surgical parameters, and complications of two techniques. Results: Bony union was achieved in all cases except one case of IN. Time to union was similar in both groups. None showed mal-union over 10° or limb length discrepancy over 1 cm. None of SP group and 2 in IN group experienced re-operation; one patient had deep infection with nonunion. The other patient sustained mal-rotation. Both patients healed after revision procedure. All patients showed excellent or satisfactory results of Flynn's criteria. The time to full-weight bearing was shorter in IN (IN: 57.3 days, SP: 89.2 days, p < 0.05). In surgical parameters, operative time seemed shorter in IN (IN: 94.7 min, SP: 104 min, p = 0.095), and fluoroscopy time was shorter in IN (IN: 58 s, SP: 109 s, p < 0.05) than SP group. Conclusion: Although both IN and SP yield good results and minimal complication in adolescent femoral fractures, IN may be advantageous in less need of fluoroscopy, technical easiness in reduction and early weight bearing. © 2011 Elsevier Ltd.

A nucleosomal protein, high mobility group box 1 (HMGB1) is known to be a late mediator of sepsis. Dabrafenib is a B-Raf inhibitor and initially used for the treatment of metastatic melanoma therapy. Inhibition of HMGB1 and renewal of vascular integrity is appearing as an engaging therapeutic strategy in the administration of severe sepsis or septic shock. Here, we examined the effects of dabrafenib (DAB) on the modulation of HMGB1-mediated septic responses. DAB inhibited the release of HMGB1 and downregulated HMGB1-dependent inflammatory responses by enhancing the expressions of cell adhesion molecules (CAMs) in human endothelial cells. In addition, treatment with DAB inhibited the HMGB1 secretion by CLP and sepsis-related mortality and pulmonary injury. This study demonstrated that DAB could be alternative therapeutic options for sepsis or septic shock via the inhibition of the HMGB1 signaling pathway. [BMB Reports 2016; 49(4): 214-219].

The aim of this study was to develop and validate a new radiographic damage scoring method (DAmagE index of GoUt; DAEGU) in chronic gout using plain radiography. Two independent observers scored foot x-rays from 15 patients with chronic gout according to the DAEGU method and the modified Sharp/van der Heijde (SvdH) method. The 10 metatarsophalangeal (MTP) and 2 interphalangeal (IP) joints of the first toes of both feet were scored to assess the degrees of erosion and joint space narrowing (JSN). The intraobserver and interobserver reliabilities were analyzed by calculating the intraclass correlation coefficient (ICC) and minimal detectable change (MDC). The correlation between the DAEGU and SvdH methods was analyzed by calculating the Spearmans rho correlation coefficients and Kappa coefficients. The DAEGU method was found to be highly reproducible (0.945-0.987 for the intraobserver and 0.993-0.996 for the interobserver ICC values). The erosion, JSN, and total scores exhibited strong positive correlations between the DAEGU and SvdH methods and also within each method (r = 0.860-0.969, P < 0.001 for all parameters). The DAEGU and SvdH methods were in very good agreement as determined by Kappa coefficient analysis [0.732 (0.387-1.000) for erosion and 1.000 (1.000-1.000) for JSN]. In conclusion, this study revealed that DAEGU method was a reliable and feasible tool in the assessment of radiographic damage in chronic gout. The DAEGU method may provide a more easy assessment of structural damage in chronic gout in the real clinical practice.

Background: Among women worldwide, major depression (MDD) and heart disease rank first and second, respectively, in burden of disease. Although selective serotonin reuptake inhibitors (SSRIs) are frequently prescribed, possible inhibition of nitric oxide (NO) function has caused concerns about their effects on protective vascular mechanisms. Our study aimed to determine the effect of SSRIs on flow-mediated vascular dilatation (FMD), platelet aggregation, and platelet NO production among women. Methods: Women (n=28) without known cardiovascular disease were recruited prior to undergoing SSRI treatment for MDD, postpartum depression (PPD), or premenstrual dysphoric disorder (PMDD). Symptoms were quantified using the Hamilton Depression/Anxiety and Beck Depression scales. FMD, platelet aggregation, and platelet NO production were measured before and after 1 month of SSRI (sertraline, fluoxetine, or paroxetine) therapy. Results: Depression and anxiety symptoms decreased significantly with SSRI treatment (ps <0.01). FMD and platelet aggregation did not differ between pre-and posttreatment, although FMD rose to the normal range (≥8%) in two of three women with abnormal FMD prior to SSRI treatment. We observed a 21% decrease (p=0.024) in platelet NO production. Conclusions: SSRI treatment had little effect on FMD or platelet aggregation. The health impact of decreased NO production is unclear, particularly in this relatively young group of women without cardiovascular disease, but should be considered in future studies focusing on SSRI safety in patients with cardiovascular disease. © 2014, Mary Ann Liebert, Inc.

To verify the practical correlation between the topographical features of the femur neck base and the ideal entry point by analyzing three-dimensional (3D) models virtually implanted with an antegrade femoral nail.A total of 103 cadaveric femurs (50 males and 53 females) were enrolled. Specimens underwent continuous 1.0mm slice computed tomography (CT) scans. CT images were rendered into 3D images using image-processing software (MimicsThe entry point of 68 models (66.0%) was the trochanteric fossa, while the others were placed around the anterior border of the trochanteric fossa. The proximal end of the nail overlapped in 50 models (48.1%), and among them, the central point of 23 models (22.3%) was obscured by trochanteric overhang. There was a statistically significant risk associated with female gender (6.02 times) and type IV overhang of Grenchenigs classification (4.56 times). Despite the precise positioning of the trochanteric fossa, 11 models (10.7%) had the entry point covered by trochanteric overhang.The ideal entry point was over the trochanteric fossa in just half of the models, and could be hindered by trochanteric overhang even though the CFN was ideally positioned.

Background: Blood culture contamination leads to inappropriate or unnecessary antibiotic use. However, practical guidelines are inconsistent about the routine use of sterile gloving in collection of blood for culture. Objective: To determine whether the routine use of sterile gloving before venipuncture reduces lood culture contamination rates. Design: Cluster randomized, assessor-blinded, crossover trial (ClinicalTrials.gov registration number: NCT00973063). Setting: Single-center trial involving medical wards and the intensive care unit. Participants: 64 interns in charge of collection of blood for culture were randomly assigned to routine-to-optional or optional-toroutine sterile gloving groups for 1854 adult patients who needed blood cultures. Intervention: During routine sterile gloving, the interns wore sterile gloves every time before venipuncture, but during optional sterile gloving, sterile gloves were worn only if needed. Measurements: Isolates from single positive blood cultures were classified as likely contaminant, possible contaminant, or true pathogen. Contamination rates were compared by using generalized mixed models. Result: A total of 10 520 blood cultures were analyzed: 5265 from the routine sterile gloving period and 5255 from the optional sterile gloving period. When possible contaminants were included, the contamination rate was 0.6% in routine sterile gloving and 1.1% in optional sterile gloving (adjusted odds ratio, 0.57 [95% CI, 0.37 to 0.87]; P = 0.009). When only likely contaminants were included, the contamination rate was 0.5% in routine sterile gloving and 0.9% in optional sterile gloving (adjusted odds ratio, 0.51 [CI, 0.31 to 0.83]; P = 0.007). Limitation: Blood cultures from the emergency department, surgical wards, and pediatric wards were not assessed. Conclusion: Routine sterile gloving before venipuncture may reduce blood culture contamination. © 2011 American College of Physicians.

Mesothelioma is a rare aggressive tumor arising from the mesothelial cell and regarded as universally fatal disease with average survival around 1 year. The incidence rate is varied from one to forty per million in different countries and increasing by the year. The most common site of tumor origin is the pleura and only 20% to 33% of mesothelioma arise from the peritoneum. There are increasing reports of malignant mesothelioma with forty to fifty fatal cases per year in Korea. Histological studies with immunohistochemical stain is helpful for the diagnosis of peritoneal mesothelioma and imaging modality alone is not sufficient for diagnosis, so it is difficult to confirm diagnosis. A 64-year-old male patient was admitted to the hospital with a palpable mass on abdomen. The 6x6 cm sized huge mass was seen on the body of stomach adjacent to the peritoneum. We report a case of malignant peritoneal mesothelioma without evident exposure to asbestos, of which direct invasion to the gastric mucosa was confirmed by endoscopic biopsy and immunohistochemical stain.

17562 Background: Multiple primary malignant tumors have been documented with increased frequency over the last two decades. An analysis of other primary cancers in individuals with non-Hodgkins lymphoma (NHL) can help to elucidate this cancer epidemics and etiology.The occurrence of multiple malignancy was studied in patients with NHL from 1985 to 2005.One or more additional cancers were observed in 19 patients. Seven were diagnosed prior to, 5 concomitantly with, and 7 after the diagnosis of NHL. The diagnosis of 5 synchronous primary cancer were rectal cancer, squamous cell esophageal cancer, prostatic cancer, transitional cell bladder cancer, and non-small cell lung cancer. Each cases of colon cancer, breast cancer, hepatoma, small cell lung cancer, stomach cancer, cervical cancer, and rhabdomyosarcoma were diagnosed prior to NHL, and the second primary cancers were two squamous skin cancer and each cases of melanoma, colon cancer, thyroid cancer, adenocarcinoma of the salivary gland, and cholangiocarcinoma. The mean age of synchronous cases was 68.2 4.8 years-old, and all 5 cases were primary extranodal NHL (2 gastric, 1 nasopharynx, 1 nasal, 1 rectal) and pathologic diagnosis were diffuse large cell in 4 cases and extranasal NK/T cell type in one case. The mean age of the second primary NHL was 57.6 11.4 years-old, and 5 of 7 cases were extranodal origin (each one case of colon, tonsil, tongue, stomach, and CNS), and were diagnosed 11, 19, 24, 72, 73, 101, 168 months after the diagnosis of variable cancers. The mean age of the second primary cancer was 46.9 15.9 years-old, and 3 of 7 cases were extranodal origin (2 gastric and 1 tonsil), and were diagnosed 55, 73, 75, 99, 144, 156, 161 months after the diagnosis of NHL.The synchronous cases of NHL were more older and more frequent extranodal manifestations than metachronous cases.
