Between 1989 and 1993, 31 patients who had undergone ACL reconstruction using autogenous patellar bone-tendon-bone were studied to evaluate the effects on knee joint function. After having harvested the central one third of the patellar tendon, it was positioned isometrically through tunnels of tibia and femur and also central defect of the patellar ligament was sutured loosely. Clinically Hospital for special surgery(HSS) knee socre by Marshall 1997, manual knee test, knee extention and flexion angles, Cybex test, KT-2000 measurments and radiological study were performed for subjective and objective symptoms at the average follow-up 33 months (range 18-72 months). Quadriceps weakness of strength less than 80% of the normal side was present in 61% of patients, patellofemoral joint pain in 15%, AP translation more than 3mm in 23%, flexion contracture of 5 degree or more in 29%. Hospital for special surgery(HSS) knee score was improved from 35 to 46 in average during follow-up period. The height of the patella was increased in 2 cases and decreased in 6 cases within normal variation which was not significant statistically. The above results indicate that importance of postoperative rehabilitation program and extension position of knee joint after surgery place a major emphasis on the avoidance of flexion contracture and on the improvement of joint function.

3.Anastomotic stricture after liver transplantation: It is not Achilles' heel anymore!
Gastrointestinal Intervention 2018;7(2):57-66
Biliary-tract complications, such as biliary strictures, anastomotic leaks, choledocholithiasis, and biliary casts, can occur after liver transplantation (LT). Of these complications, biliary strictures are regarded as an Achilles' heel. Recently, treatment of anastomotic biliary stricture (ABS) has transitioned from conventional surgical revision to a nonsurgical treatment modality. Endoscopic serial balloon dilatation and/or multiple plastic stent replacements are highly effective and are now regarded as the first-line treatments. However, if the patient has undergone anastomosis by means of a hepaticojejunostomy, percutaneous treatment is performed. With recent technological advances and the rendezvous method, the clinical success rates of endoscopic and percutaneous ABS treatments have increased, but these methods fail in some patients who have total obstruction of anastomotic stricture. For these patients, magnetic compression anastomosis (MCA) has been suggested as an alternative method. Animal and human studies have demonstrated the safety and efficacy of MCA, and advancements in these nonsurgical methods have increased the clinical success rate of ABS. This review focuses on ABSs that develop after LT and discusses the clinical results of various nonsurgical methods and future directions.

4.Drug-eluting Biliary Stent
Korean Journal of Pancreas and Biliary Tract 2020;25(1):11-17
Biliary drainage is necessary to improve the survival or quality of life of patients with malignant biliary obstruction. In the past, surgery was the primary treatment for biliary drainage, but recently, endoscopic or percutaneous stent implantation has been recognized as the main treatment. Various materials and structures have been devised and developed to increase the patency of the biliary stent. In the development of these stents, drug-eluting biliary stents with an anti-tumoral agent (DES) have emerged to increase the stent patency period by chemically inhibiting tumor growth in the stent through the change of the coating material. The DESs have been proved to be stable through several animal and clinical trials, but their effectiveness has not been demonstrated. We will discuss the development process, problems, and future directions of DES that has been clinically applied.

The papillary cystadenoma in the scrotum is a rare benign tumor. But papillary cystadenoma needs a observation about stigma of malignant combination. We experienced a case of this, which didn't show the evidence of malignancy. We report this rare tumor.

BACKGROUND: Exposure to organic solvents becomes a common problem to workers of heavy industries in Korea. A number of volatile organic solvents which are frequently used in painting can cause various derangements of the nervous system, especially cognitive impairments and peripheral neuropathy. METHODS: This study was carried out on 190 workers as a control group who had never been exposed to organic solvents and on 674 spray painters with long-term exposure to organic solvent mixtures. The major components of organic solvent mixtures were determined. All subjects underwent neurological examination as well as routine physical check-up after completing questionnaires on general, musculoskeletal, neuropsychiatric and neurological systems. Subjects with abnormal findings on neurological examination related with the exposure of organic solvent mixtures took further neuropsychological and neurophysiological tests. RESULTS: The prevalence rates of cognitive impairments and of peripheral neuropathy in the exposed group were significantly higher than the control group (9.5% vs 2.1% and 2.1% vs 0%, respectively). High exposure group (more than 2.64 of cumulative exposure index, CEI) showed also higher prevalence of cognitive impairments and of peripheral neuropathy than low exposure group (cognitive impairments; 12.3% vs 6.4%, peripheral neuropathy; 2.3% vs 1.8%). Most common cognitive impairments were attentional deficit, and abnormal sense on the extremities or face was most common symptom of the peripheral nervous system. CONCLUSION: This study is the first large-scale, case-control study extensively evaluating cognitive impairments and peripheral neuropathy related with volatile organic solvent mixtures in spray painters working in a shipbuilding industry in Korea. The results show that the prevalence rates of cognitive impairments and of peripheral neuropathy are relatively low, but clearly related with the exposure extent of organic solvents.

Coronary stent dislodgement is a rare complication of percutaneous coronary intervention. We report a case of stent dislodgement in the ascending thoracic aorta. The stent was mechanically distorted in the left circumflex artery (LCX) while being delivered to the proximal LCX lesion. The balloon catheter was withdrawn, but the stent with the guide wire was remained in the ascending thoracic aorta. The stent was unable to be retrieved into the guide catheter, as it was distorted. A goose neck snare was used successfully to catch the stent in the ascending thoracic aorta and retrieved the stent externally via the arterial sheath.

Poisoning may result from self-injection. Previous reports have described acute cholinergic crisis, intermediate syndrome, and delayed toxicity resulting from parenteral organophosphate administration. These complications have been managed with antidotal and conservative treatment. Acute kidney injury was not listed among the complications. We report a case of acute kidney injury after intravenous injection with an unknown liquid. After chemical composition analysis, organophosphate dichlorvos has been identified as the injected liquid substance. A 50-year-old man injected this into his left arm. He visited the emergency department with a mental change accompanied by seizure. During admission, there were no typical cholinergic symptoms or intermediate syndrome; however, there was a development of acute oliguric kidney injury. The patient was treated successfully with a combination of hemodialysis, hemoperfusion, and conservative management. The manifested seizure, altered mental state, and acute kidney injury could have been caused by several types of poisoning. Based on patient history, which was obtained during the early treatment period, there was no information of what the injected material may have been, and there were no signs of a typical organophosphate toxidrome. However, the patient was successfully treated with rapid initiation of renal replacement treatment, without the use of antidotes. Poisoning by unknown causative substances poses a diagnostic challenge to emergency physicians. In many cases, treatment may be delayed while the physician tries to identify the toxin. However, the basic toxicology principle of focusing on the patient treatment rather than the poisonous substance should not be forgotten.
