BACKGROUND: To assess the incidence of venous thromboembolism (VTE) following shoulder surgery and to evaluate the role of postoperative duplex ultrasonography. METHODS: The study comprised a total of 224 patients who underwent shoulder surgery, including 180 shoulder arthroscopic surgeries, 28 shoulder arthroplasties, and 16 plate fixations for proximal humerus fracture between January 2014 and December 2014. The mean age of patients was 59.0 years, and there were 81 men and 143 women. Clinical data, including body mass index, blood tests, metabolic work-up for liver and renal function, previous, and present medical history, were evaluated. Duplex ultrasonography in the operative arm was performed on 2 to 4 days after surgery. RESULTS: The overall incidence of VTE following shoulder surgery was 0.45% (1/224). One patient with open reduction and plate fixation for proximal humerus fracture had asymptomatic deep vein thrombosis that showed complete remission after anticoagulant medication during a 2-month period. Four patients had asymptomatic superficial cephalic vein thrombosis and complete remission without any treatment. There was no case of pulmonary embolism. CONCLUSIONS: The incidence of VTE following shoulder surgery was extremely low in Asians. Duplex ultrasonography may be not considered a routine follow-up of shoulder surgery and can be selectively performed in high-risk or symptomatic patients for VTE.

The congenital long-QT syndrome (LQTS) is characterized by recurrent syncope, prolonged QT intervals, QT interval lability, polymorphic ventricular tachycardia, and sudden death. We report a case of congenital long QT syndrome in a 28-day-old male infant who presented with syncope, bradycardia with 2: 1 pseudo-atrioventricular block and a markedly prolonged QT inteval. One episode occured after crying and degenerated into ventricular fibrillation and terminated after cardioversion. A VVI type cardiac pacemaker was implanted. Subsequently, the infant's heart rate was over 110/min and 2: 1 AV block and any other arrhythmia were absent. The infant recovered from the accompanied pneumonia and sepsis and was discharged 47 days after adrnission. However, 13 days after discharge, the infant returned to our hospital ER with syncope. Ventricular fibrillation ceased after cardioversion. Despite medication with propranolol, ventricular tachycardia persisted. The infant expired the day after he was discharged against medical advice.

Forty cases of infiltrating duct carcinoma of the breast were examined immunohistochemically for expression of TGF-beta and angiogenesis in order to analyze significant correlation with prognostic parameters including tumor size, axillary lymph node metastasis, clinical stage, histologic grade, estrogen receptor and progesterone receptor status. The TGF-beta expression was observed in tumors center and advancing edges of tumors. To determine microvessel density for angiogenesis, we stained endothelial cells for Factor VIII related antigen and counted microvessel within tumor. The results were as follows: 1) The strong immunohistochemical expression of TGF-beta and higher counts of microvessels were observed in advancing edges of tumors (p<0.05). 2) The TGF-beta expression in the advancing edges of tumors was closely related to clinical stage and presence of axillary lymph node metastasis (p<0.05). 3) The mean microvessel counts were significantly higher in tumors from patients with axillary lymph node metastasis and increased with increasing clinical stage (p<0.05). 4) The TGF-beta expression was not related to histologic grade, estrogen receptor and progesterone receptor status(p>0.05). Therefore, the results suggested that the TGF-beta expression and angiogenesis in infiltrating duct carcinoma of the breast may play an important part in prognostic factors, closely related to the lymph node metastasis and clinical stage.

5.Imaging Finding of Multiple Endocrine Neoplasia Type 1: Case Report.
Journal of the Korean Society of Medical Ultrasound 2012;31(4):247-249
Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant inherited syndrome with characteristic clinical and radiological manifestations. Many reports on MEN1 have been published; however, no cases of radiologically diagnosed MEN1 have been reported. Therefore, we report on a radiologically diagnosed case of MEN1 with clinical symptoms of gastroduodenal ulcer.

6.Laser in Situ Keratomileusis Versus Laser Epithelial Keratomileusis for Low to Moderate Myopia.
Journal of the Korean Ophthalmological Society 2003;44(6):1297-1304
PURPOSE: To compare the efficacy, predictability, safety, and stability of Laser epithelial keratomileusis (LASEK) with conventional Laser in situ keratomileusis (LASIK) for correction of low to moderate myopia. METHODS: In this study, LASIK-treated 31 eyes of 17 patients and LASEK-treated 33 eyes of 17 patients were followed for 6 months. Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), manifest refraction, IOP, topography, keratometry, pachymetry and specular examination were performed. RESULTS: Postoperative mean UCVA was logMAR 0.02+/-0.09 in LASIK group and logMAR 0.01+/-0.09 in LASEK group. Postoperative mean refraction was 0.04+/-0.36D in LASIK group and 0.07+/-0.28D in LASEK group and there was no significant difference between 2 groups (P>0.05). 71.0%(22 of 31) of LASIK eyes and 81.8%(27 of 33) of LASEK eyes had an uncorrected visual acuity of 20/20 or better at 6 months after surgery. 87.1%(27 of 31) of LASIK eyes and 97.0%(32 of 33) of LASEK eyes achieved predictability within +/-0.5D at 6 months follow up. There was no decrease in best-corrected visual acuity of two Snellen lines or more in both groups. CONCLUSIONS: In this study, there was no difference in postoperative mean UCVA and mean refraction in LASIK and LASEK group. However, LASEK group had better results in UCVA of more than 20/20 and predictability but there was no significant difference between 2 groups.

7.Evaluation and Treatment of Recurrent Acute Pancreatitis.
Korean Journal of Pancreas and Biliary Tract 2016;21(1):1-10
Acute recurrent pancreatitis (ARP) refers to a clinical condition characterized by repeated episodes of acute pancreatitis, diagnosed retrospectively after at least the second episode of acute pancreatitis. It is still controversial that acute pancreatitis can progress to chronic pancreatitis, and acute, acute recurrent and chronic pancreatitis is a continuum of disease. The causes of ARP can be divided into mechanical, hereditary and metabolic factor. Despite recent advances in diagnostic technologies, the etiology of ARP still remains unknown in up to 30% of cases. Especially in recurrent episode of idiopathic pancreatitis, a clinician should be considered not only the common causes of ARP, such as gallstone disease and alcohol, but also rare causes of ARP. The common causes of 'idiopathic' recurrent pancreatitis are microlithiasis, sludge, sphincter of oddi dysfunction, pancreas divisum and hereditary pancreatitis. Various treatment options, such as cholecystectomy, endoscopic sphincterotomy, medical and surgery can be applied according to the identified etiology of ARP and treatment should be individualized. Currently, endoscopic treatment is increasingly performed and served as a curative treatment strategy. The medical treatment can be an option in microlithiasis and sludge, but it has limitation in terms of systemic side effect, efficacy and lack of long term outcome. Endoscopic treatment should be considered in selected patients with identifiable cause, and post procedural complication should be considered before endoscopic treatment.

OBJECTIVES: Anterior tunnelling technique consist of anterior cervical fractional interspace decompression without fusion. This method provides sufficient space for adequate neuroforaminal decompression but avoids the need for fusion or fixation. We report early clinical results of 32 cases that underwent anterior tunnelling operation for treatment of cervical radiculopathy. METHODS: This method is identical to conventional approach until the exposure of anterior cervical body and bilateral retraction of longus colli is made. A vertical window is then made at the vertebral bodies and disc space lateral to the insertion site of the longus colli. The window is deepened with drilling that follows a tunnelling fashion down to the compressive lesion. We analyzed clinical results from 32 patients who treated between December 1998 and August 2000. RESULTS: Satisfactory results were obtained in 87% of the patients. Two patients required revision surgery. None revealed surgical spinal instability on last follow-up. CONCLUSION: Anterior tunnelling operation is an acceptable surgical option for the treatment of cervical radiculopathy. Its advantages are short hospitalization, minimal postoperative discomfort, and technical feasibility.

The endemic status of clonorchiasis and metagonimiasis along the Geum-gang (River) in Okcheon-gun (County) in Korea was examined. From February to December 2000, stools of total 1,081 inhabitants living in 5 villages were examined. Each stool specimen was examined by both the cellophane thick smear method and the formalin-ether sedimentation technique. Egg-positive cases were further analyzed by Stoll's egg-counting technique, and praziquantel was administered to positive cases. The egg-positive rates for Clonorchis sinensis and Metagonimus species were 9.3% and 5.5%, respectively, and the double infection rate was 3.5%. The numbers of eggs per gram (EPG) of feces of C. sinensis and Metagonimus sp. were 918 +/-1.463 and 711+/-947, respectively. The egg-positive rates for C. sinensis and Metagonimus sp. in the riverside area were 14.2% and 8.4%, respectively, which were significantly higher than those of the inland area (3.2% and 1.7%, respectively). The egg-positive rates of C. sinensis and Metagonimus sp. in males (16.7% and 10.0%) were significantly higher than those of females (3.5% and 1.8%). However, there were no significant differences of EPG values between localities and sexes. The prevalence of clonorchiasis and metagonimiasis in this survey was significantly lower than that in the previous reports. However, there is still a high prevalence of infection with C. sinensis and Metagonimus sp. in this region, especially in the riverside area.
