Drainage of pancreatic abscesses is required for effective control of sepsis. Endoscopic ultrasound (EUS)-guided endoscopic drainage is less invasive than surgery and prevents local complications related to percutaneous drainage. Endoscopic drainage with stent placement in the uncinate process of the pancreas is a technically difficult procedure. We report a case of pancreatic abscess treated by repeated EUS-guided aspiration and intravenous antibiotics without an indwelling drainage catheter or surgical intervention.

Testicular granulosa cell tumor(GCT) is a rare neoplasm. We report here on an incidentally discovered testicular granulosa cell tumor in a 36-year-old man. The serum tumor markers were within the normal limits. The ultrasonographic findings revealed a mass with a heterogenous hypoechoic echotexture, including multiple variable sized cystic components. The histology on the orchiectomy specimen demonstrated a gonadal stromal tumor with granulosa cell features. Testicular granulosa cell tumor of the adult type is a very rare tumor, and there have been several isolated case reports and small serial studies described in the literature.

PURPOSE: This study examined the effect of a varus positioned femoral stem after cementless proximal fitting total hip arthroplasty. MATERIALS AND METHODS: A total of 144 hips in 136 patients who underwent cementless total hip arthroplasty, were followed-up. Twenty-one varus positioned hips were compared with 123 neutral positioned hips. The clinical results were analyzed according to the level of thigh pain and the Harris Hip score. The radiological outcome was assessed according to osteolysis, loosening and stem failure. RESULTS: In the varus positioned hips, thigh pain was present in 1 hip, and the average Harris Hip Score was 96 points. None of the implants showed radiological evidence of loosening or impending failure. Localized osteolysis was identified in 1 hip, non-progressive radiolucencies in 2 hips, and cortical hypertrophy in 1 hip. In the neutral positioned hips, thigh pain was present in 6 hips, and the average Harris Hip Score was 97 points. Localized osteolysis was identified in 8 hips, non-progressive radiolucencies in 7 hips, cortical hypertrophy in 9 hips. CONCLUSION: Patients with varus alignment of the stem did not present poorer clinical outcomes than those with neutral alignment of the stem.

PURPOSE: Adenotonsillar hypertrophy (ATH) that causes upper airway obstruction might lead to chronic hypoxemic pulmonary vasoconstriction and right ventricular (RV) dysfunction. We aimed to evaluate whether adenotonsillectomy (T&A) in children suffering from obstructive sleep apnea (OSA) due to severe ATH could improve RV function. METHODS: Thirty-seven children (boy:girl=21:16; mean age, 9.52±2.20 years), who underwent T&A forsleep apnea due to ATH, were included. We analyzedthe mean pulmonary artery pressure (mPAP), the presence and the maximal velocity of tricuspid regurgitation (TR), the tricuspid annular plane systolic excursion (TAPSE), and the right ventricular myocardial performance index (RVMPI) with tissue Doppler echocardiography (TDE) by transthoracic echocardiography pre- and post-T&A. The follow-up period was 1.78±0.27 years. RESULTS: Only the RVMPI using TDE improved after T&A (42.18±2.03 vs. 40±1.86, P=0.001). The absolute value of TAPSE increased (21.45±0.90 mm vs. 22.30±1.10 mm, P=0.001) but there was no change in the z score of TAPSE pre- and post-T&A (1.19±0.34 vs. 1.24±0.30, P=0.194). The mPAP was within normal range in children with ATH, and there was no significant difference between pre- and post-T&A (19.6±3.40 vs. 18.7±2.68, P=0.052). There was no difference in the presence and the maximal velocity of TR (P=0.058). CONCLUSION: RVMPI using TDE could be an early parameter of RV function in children with OSA due to ATH.

PURPOSE: To compare the results of anterior segment biometry including white-to-white (WTW) between scanning-slit topography (ORBscan IIz(R), Bausch & Lomb), optical low-coherence reflectometry (OLCR) biometry (Lenstar(R), Haag-Streit), and Castroviejo calipers. METHODS: Measurements on 72 eyes of 36 patients that underwent refractive surgery were measured using ORBscan(R), Lenstar(R), and calipers and compared. Ocular biometry parameters used in this study included the WTW, central corneal thickness, anterior chamber depth (ACD), keratometry, and pupil size. RESULTS: The WTW measurements using ORBscan(R) and calipers (11.57 +/- 0.35 mm and 11.58 +/- 0.34 mm, respectively) were statistically similar. However, the measurement using Lenstar(R) (12.05 +/- 0.40 mm) was significantly greater than with the other methods (p < 0.001). Central corneal thickness and keratometry measurements using ORBscan(R) were greater than when using Lenstar(R) (p = 0.01 for both). ACD and pupil size measurement using Lenstar(R) were greater than when using ORBscan(R) (p < 0.001 for both). CONCLUSIONS: Because WTW and ACD measurements using Lenstar(R) were greater than when using ORBscan(R) and calipers, unexpected high-vaulting may be observed due to the selection of a larger-sized posterior chamber phakic intraocular lens. Therefore, the differences in measurements obtained when using these methods should be considered.

PURPOSE: Pancreatic neuroendocrine tumors (PNET) are a rare subgroup of tumors. For PNETs, the predictive factors for survival and prognosis are not well known. The purpose of our study was to evaluate the predictive factors for survival and disease progression in PNETs. MATERIALS AND METHODS: We retrospectively analyzed 37 patients who were diagnosed with PNET at Severance Hospital between November 2005 and March 2010. Prognostic factors for survival and disease progression were evaluated using the Kaplan-Meier method. RESULTS: The mean age of the patients was 50.0+/-15.0 years. Eight cases (21.6%) were described as functioning tumors and 29 cases (78.4%) as non-functioning tumors. In univariate analysis of clinical factors, patients with liver metastasis (p=0.002), without resection of primary tumors (p=0.002), or American Joint Committee on Cancer/Union for International Cancer Control (AJCC/UICC) stage III/IV (p=0.002) were more likely to demonstrate shorter overall survival (OS). Patients with bile duct or pancreatic duct invasion (p=0.031), sized-lesions larger than 20 mm (p=0.036), liver metastasis (p=0.020), distant metastasis (p=0.005), lymph node metastasis (p=0.009) or without resection of primary tumors (p=0.020) were more likely to demonstrate shorter progression-free survival (PFS). In multivariate analysis of clinical factors, bile duct or pancreatic duct invasion [p=0.010, hazard ratio (HR)=95.046] and tumor location (non-head of pancreas) (p=0.036, HR=7.381) were confirmed as independent factors for predicting shorter PFS. CONCLUSION: Patients with liver metastasis or without resection of primary tumors were more likely to demonstrate shorter OS. Patients with bile duct or pancreatic duct invasion or tumors located at body or tail of pancreas were more likely to demonstrate shorter PFS.

BACKGROUND/AIMS: Pleuropulmonary paragonimiasis produces no specific symptoms or radiologic findings, allowing for the possibility of misdiagnosis. We evaluated the specific clinical and pleural fluid features of pleuropulmonary paragonimiasis masquerading as pleural tuberculosis. METHODS: We retrospectively analyzed the clinical and radiologic characteristics of 20 patients diagnosed with pleuropulmonary paragonimiasis between 2001 and 2011. RESULTS: In total, 17 patients presented with respiratory symptoms, including dyspnea (30%), hemoptysis (20%), cough (20%), and pleuritic chest pain (15%). Chest radiographs revealed intrapulmonary parenchymal lesions, including air-space consolidation (30%), nodular opacities (20%), cystic lesions (15%), ground-glass opacities (10%), and pneumothorax (5%). A pleural f luid examination revealed eosinophilia, low glucose levels, and high lactate dehydrogenase (LDH) levels in 87%, 76%, and 88% of the patients, respectively. These traits helped to distinguish pleuropulmonary paragonimiasis from other pleural diseases such as parapneumonic effusion, malignancy, and pleural tuberculosis. CONCLUSIONS: Pleuropulmonary paragonimiasis is often initially misdiagnosed as other pleural diseases. Therefore, it is important to establish the correct diagnosis. In patients with unexplained pleural effusion living in paragonimiasis-endemic areas, pleural fluid obtained by thoracentesis should be examined to distinguish pleuropulmonary paragonimiasis. When marked eosinophilia, high LDH levels, and low glucose levels are identified in pleural fluid, physicians could consider a diagnosis of pleuropulmonary paragonimiasis.

BACKGROUND/AIMS: 18F-Fluorodeoxyglucose positron-emission tomography (18F-FDG PET) has been used to assess the biological behavior of hepatocellular carcinoma (HCC). In this study, we investigated the usefulness of 18F-FDG PET for predicting tumor progression and survival in patients with intermediate Barcelona Clinic Liver Cancer (BCLC) intermediate-stage HCC treated by transarterial chemoembolization (TACE). METHODS: From February 2006 to March 2013, 210 patients treated with TACE, including 77 patients with BCLC intermediate-stage HCC, underwent examination by 18F-FDG PET. 18F-FDG uptake was calculated based on the tumor maximum (Tmax) standardized uptake value (SUV), the liver mean (Lmean) SUV, and the ratio of the Tmax SUV to the Lmean SUV (Tmax/Lmean). RESULTS: The mean follow-up period for the 77 patients (52 males, 25 females; average age, 63.3 years) was 22.2 months. The median time to progression of HCC in patients with a low Tmax/Lmean (< 1.83) and high Tmax/Lmean (> or = 1.83) was 17 and 6 months, respectively (p < 0.001). The median overall survival time of patients with a low and high Tmax/Lmean was 44 and 14 months, respectively (p = 0.003). Multivariate analysis revealed that the Tmax/Lmean was an independent predictor of overall survival (hazard ratio [HR], 1.96; 95% confidence interval [CI], 1.210 to 3.156; p = 0.006) and tumor progression (HR, 2.05; 95% CI, 1.264 to 3.308; p = 0.004). CONCLUSIONS: 18F-FDG uptake calculated by the Tmax/Lmean using PET predicted tumor progression and survival in patients with BCLC intermediate-stage HCC treated by TACE.
