Lipoblastoma is a benign tumor which frequently arises in the limbs but rarely in the mediastinum, and is common in children under the age of three years. We report a case of mediastinal lipoblastoma in a 27-month-old female child complaining of dyspnea. Plain radiography demonstrated a huge well-defined mass in the me-diastinum, while CT scanning revealed a soft tissue mass with an internal hypodense portion. When radi-ographic images in children under the age of three reveal a soft tissue mass with a fat component in the mediastinum, especially where there is no calcification or a cystic component, lipoblastoma should be included in the differential diagnosis.

Purpose: This study was performed to analyze the predictors that might contribute to urinary retention following semiclosed hemorrhoidectomy under spinal anesthesia. Methods: This retrospective study enrolled 2,176 consecutive patients with symptomatic grade III to IV hemorrhoids who underwent semiclosed hemorrhoidectomy between September 2018 and September 2019. Results: Among the 2,176 patients, 1,878 (86.3%) had no postoperative urinary retention, whereas 298 (13.7%) developed urinary retention after hemorrhoidectomy. The percentage of males was significantly higher in the retention group than in the non-retention group (60.4% vs. 48.1%; P=0.001). The risk of urinary retention was 1.52-fold higher in males than in females (95% confidence interval [CI], 1.13–2.04; P=0.005), 1.62-fold higher in old age (95% CI, 1.14–2.28; P=0.006), and 1.37-fold higher with high body mass index (BMI) (95% CI, 1.04–1.81; P=0.025). Patients with ≥4 resected hemorrhoids had a higher odds ratio (OR) of 1.46 (95% CI, 1.12–1.89; P=0.005) than patients with <4 resected hemorrhoids. Among the supplementary medication, patients who used analgesics had a higher OR of 2.06 (95% CI, 1.57–2.68; P=0.001) than those who did not. Conclusion Male sex, age, high BMI, number of resected hemorrhoids, and supplementary analgesics are independent risk factors for urinary retention after semiclosed hemorrhoidectomy.

Purpose: According to recent studies, magnetic resonance imaging (MRI) assessment of complex fistulas provides a significant benefit compared to fistulography, computed tomography, and ultrasonography. The aim of this study was to describe the accuracy of MRI and the importance of identifying puborectalis muscle involvement on MRI in patients with complex fistula. Methods: All patients who were clinically diagnosed with ‘complex’ or showed multiple fistula tracts underwent fistula MRI. Eligible patients were consecutive patients who underwent fistula MRI between September 2018 and September 2019 at our hospital. Results: A total of 83 patients (74 males, 9 females; 116 tracts) were included in this study. The sensitivity and specificity of MRI in diagnosing fistula tracts were 94.8% and 98.2%, respectively. The sensitivity and specificity in identifying internal opening were 93.9% and 97.3%, respectively. Of the 35 patients with puborectalis muscle involvement in the MRI, 31 images of suprasphincteric-type patients on the Park’s classification were classified. The patients of puborectalis involvement were divided into 2 groups according to the surgical procedure that was performed. There were 12 sphincter-saving procedures and 19 sphincter division procedures performed. Recurrence was seen in 2 patients in the sphincter-saving procedure group, while no case was seen in the sphincter division procedure group. Five complications were found in the sphincter division procedure group, of which 2 reported incontinence. Conclusion Fistula MRI is a highly accurate examination for evaluating complex fistulas, and the puborectalis muscle involvement findings are very important for diagnosis and treatment.

OBJECTIVE: To investigate the frequency, type and severity of cardiac abnormalities in the patients with ankylosing spondylitis and undifferentiated spondyloarthopathy. METHODS: A history, clinical examination, standard 12 lead electrocardiography, two dimensional, M mode, and Doppler echocardiographies were performed on 19 patients with ankylosing spondylitis, 15 patients with undifferentiated spondyloarthropathy and 21 normal controls. RESULTS: 1) Cardiac abnormalities were detected in 8 patients(42.1%) with ankylosing spondylitis. 2) Cardiac abnormalities were detected in 8 patients(53.3%) with undifferentiated spondyloarthropathy including 2 patients with aortic valve abnormalities(mild aortic insufficiency, aortic valve thickening. 3) Cardiac abnormalities were detected in one (4. 8%) among normal controls (mild tricuspid regurgitation). 4) There were sinus bradycardias on electrocardiography in 2 patients among patients witn anl;ylosing spond!litis and in 1 patient among undifferentiated spondyloarthropathy. But there was no conduction disturbance in both groups. 5) The frequency of cardiac abnormality was higher in patients with ankylosing spondylitis and undifferentiated spondyloarthropathy than in normal controls. 6) The mean age, mean disease duration, presence of uveitis, peripheral arthritis, HLA-B27, enthesopathy, Schober test and chest expansion in the patients with ankylosing spondylitis and undifferentiated spondyloarthropathy with cardiac abnormalities were not different from those in the patients without cardiac abnormalities. CONCLUSION: The frequency of cardiac abnormality was higher in patients with ankylosing spondylitis and undifferentiated spondyloarthropathy than in normal controls. The frequency, type and severity of cardiac involvement in patients with ankylosing spondylitis were not different from those in patients with undifferentiated spondyloarthropathy.

Using 3D ultrasound, bilateral chylothorax was diagnosed antenatally in the second trimester. Apparently stable, bilateral pleural effusion progressed rapidly to severe hydrops with facial edema during observation, and then we decided bilateral pleural-amniotic shunt operation. Here we present a case where drainage of pleural effusion by a double reverse pig tail stent made by ourself was achieved, although placement of the thoracoamniotic shunt resulted in near complete drainage of bilateral pleural effusion with normalization of intrathoracic anatomic relationships, subsequent resolution of fetal hydrops, but the ultimate outcome was unsuccessful due to the internalization of one catheter and unknown sudden death. We think that ongoing research is required to further evaluation about complications associated with this procedure, specifically failure of function due to obstruction, migration of the catheter,

Sacrococcygeal teratoma is the most common solid tumor to occur in neonates, in whom it mostly takes the form of an obvious exophytic mass. They are, however, rarely found in adults. We report the CT and histopathologic findings of an adult cystic teratoma arising from the lower sacrococcygeal region that was discovered incidentally. Unenhanced CT scans showed an oval-shaped, cystic lesion with hyperattenuating content and no contrast enhancement. After surgery, the gross specimen was seen to be a cystic lesion filled with mucin. Microscopy revealed three germ cell layers in the cystic wall and the lesion was confirmed as cystic teratoma.

A newly developed third generation enzyme immunoassay(Lucky HCD 3.0 EIA) for hepatitis C virus(HCV) antibodies was added with the envelope(E1E2)/NS4 fusion proteins and expanded NS5 proteins as well as the core/NS3 fusion proteins. Authors evaluated the HCD 3.0 EIA with the previously available second generation EIA(HCD 2.0) in 10,435 Red Cross blood donors. Among 10,435 donors who were screened for the presence of HCV antibodies by HCD 2.0 assay, 22(0.21%) sera were repeatedly reactive. All of these sera were tested for further testing. Only 13 of all tested sera were reactive by HCD 3.0 EIA, and nine sera were not reactive. Nine of 13 HCD 3.0 positive sera were reactive by recombinant immunoblot assay(Lucky-Confirm). Also seven of these 13 sera had detectable HCV genomic RNA by reverse transcriptase-polymerase chain reaction(RT-PCR). None of nine HCD 3.0 negative samples had detectable immunoblot assay and HCV genomic RNA. It is concluded that the new HCV EIA can decrease a significant false positivity of second generation EIA in a blood donor population. This new assay correlates well with detection of HCV-RNA by RT-PCR and identifies donors who are truly infected.
