Notch stenosis had been thought to be related with anterior cruciate ligament (ACL) injury. The purpose of this study is to evaluate the possible relationship between notch stenosis and ACL injury. We measured the notch seen on the axial section in MRI at popliteal groove. We have retrospectively analyzed 116 cases of knee MRI. All cases were divided into three groups ; Group I were fifty six normal knee. Group II were thirty knee with contact ACL injuries. Group III were thirty knee with non contact ACL injuries. The result were as follows; 1. Statistically significant difference was found in the notch width index (NWI) between group I and group III but no significant differences was found in the NWI between group I and group II. 2. Statistically significant correlation to non-contact ACL injuries was found in the NWI at both anterior and posterior outlet of the notch. 3. An unique shape of the notch was found in the majority of group III.There seemed to be an obvious relationship between notch stenosis and non-contact ACL injuries.

Although the mediastinum is the second favorite location of primary teratoma in adults, primary malignant teratoma in mediastinum is rare in incidence. Malignant teratoma includes teratocarcinoma, immature teratoma and malignant transformation in benign teratoma. The latter is rarer than others types, and undifferentiated or squamous cell carcinoma are the major incidence. We experience a case of unique adenocarcinoma composed of signet ring cells in mature teratoma of mediastinum and brief review of the literatures are included.

We studied 30 patients who participated in accelerated rehabilitation program after ACL reconstruction to evaluate the effects on knee joint function prospectively. This program emphasizes early full hyperextension, early weight bearing as tolerated, and closed-chain quadriceps functional activities with rapid return to sports. Timing of the return to occupation, activity level, manual knee test, range of motion, thigh circumference, Lysholm knee score and KT-2000 arthrometer measurement were checked at the latest follow-up which is at least more than 1 year. The result were as follows: 1. The mean time for patients to return to occupation was 7.5 weeks (2 weeks-6 months). 2. Range of motion of the knee were not limited in 25 cases (83%) at 1 year after reconstruction. 3. The mean Lysholm score was 92.7. 4. The mean manual maximum KT-2000 arthrometer score was 2.0mm. The results of this study show that patients who had an ACL reconstruction with an autogenous central 1/3 patellar tendon graft and followed an accelerated rehabilitation program obtained longterm stability, achieved full range of motion, had a low complication rate, and were able to return to full sporting activities predictably.

Cryoglobulinemia, first described by Wintrobe and Buell in 1933, is characterized by the presence of serum immunoglobulins that precipitate below 37degrees C and that dissolve on rewarming. Although the actual mechanism of cryoprecipitation and the etiology of cryoglobulinemia remains obscure, it is frequently associated with other systemic diseases, such as hepatitis C virus (HCV) infection, multiple myeloma, Sjogren's syndrome, B cell lymphoma, and systemic lupus erythematosus. No cases of cryoglobulinemia associated with B cell lymphoma have ever been published in the Korean medical literature, and few such cases have been reported in other countries. Herein, we report on a rare and interesting case of cryoglobulinemia developed in a patient with gastric diffuse large B cell lymphoma.

PURPOSE: Metabolic syndrome (MS) is a clinical condition that shares many common characteristics with diabetes. However, unlike diabetes, the usefulness of MS as a prognostic entity in peripheral arterial disease is uncertain. This study evaluated the prognostic usefulness of MS in critical lower limb ischemia (CLI) patients. MATERIALS AND METHODS: We compared the 2-year clinical outcomes in 101 consecutive CLI patients (66+/-14 years; 78% men) with 118 affected limbs treated with percutaneous transluminal angioplasty (PTA) according to the presence of MS and diabetes. RESULTS: The number of MS patients was 53 (52%), of which 45 (85%) had diabetes. During a 2-year follow-up, the incidence of clinical outcomes, including reintervention, major amputation, minor amputation, and survival, was not significantly different between MS and non-MS patients; however, the incidence of minor amputation was significantly higher in diabetic than in non-diabetic patients (42% vs. 17%; p=0.011). Cox regression analysis for the 2-year primary patency demonstrated no association between MS and 2-year primary patency [hazard ratio (HR), 1.02; 95% confidence interval (CI), 0.45-2.30; p=0.961], whereas there was a significant association between diabetes and 2-year primary patency (HR, 2.81; 95% CI, 1.02-7.72; p=0.046). Kaplan-Meier analysis revealed no significant difference in the 2-year primary patency between MS and non-MS patients; however, the 2-year primary patency was lower in diabetic than in non-diabetic patients (p=0.038). CONCLUSION: As a prognostic concept, MS might conceal the adverse impact of diabetes on the prognosis of CLI patients treated with PTA.

OBJECTIVE: To evaluate the clinical efficacy of a new air cleaning device (LG Electronics, Korea) equipped with electrostatic precipitator (EP) and photocatalytic plasma filter (PCP) in 24 respiratory allergic subjects. MATERIAL AND METHOD: Air cleaning conditioner and air cleaner were placed in living room and bedroom. Both EP and PCP (EP/PCP) filters were used for the first 4 weeks and for another 4 weeks, PCP without EP filter (PCP) was used. We measured symptom scores of asthma and rhinitis, peak expiratory flow rate (PEFR), serum eosinophil cataionic prote in? in ECP, Dermatophagoides farinae (DF) specific IgE and IgG in sera, concentrations of major allergens of DF in floor dust of living room, bedroom and in airborne dust. RESULTS: Both asthma and rhinitis symptom scores were significantly improved not only with EP/PCP filters but also with PCP filter. The morning PEFR was significantly improved with EP/PCP filters, but not with PCP filter. Frequency of salbutamol inhalation by air cleaner with EP/PCP filter tended to de crease(p=0.051), with no significant difference in serum ECP concentration. DF specific IgE significantly decreased at the 8th week with no differences in specific IgG. However, the mean Der f I levels in floor dust of bedroom (1, 128 vs. 374 ng/gm dust, p<0.01) and living room (1,516 vs 812 ng/gm dust, p<0.01) decreased, Der f1 in airborne dust measured only in 8 out of 22 subjects, and they decreased significantly with the trial of EP/PCP filter (172.2 pg/4.5m vs. 62.1 pg/4.5m, p<0.01). CONCLUSION: These results suggest that the EP/PCP air cleaner may be an effective tool for environmental control in respiratory allergic subjects.

BACKGROUND AND OBJECTIVES: Transcatheter device closure becomes the first option for treating secundum atrial septal defect (ASD), but the conventional method is sometimes unsuccessful even when the defect size indicates the closure to be feasible. To increase the success rate, modified methods have been introduced and used. This study aimed to find predictors for using the modified methods in the device closure of secundum ASDs. SUBJECTS AND METHODS: Between October 2010 and December 2012, 92 patients with ASDs underwent the transcatheter device closure. We analyzed the sizes of the defect, the surrounding rims, and the ratios of the left atrium (LA) dimensions to the device size in the patients who underwent the procedure either using the conventional or modified methods. RESULTS: Among the 88 successful cases (95.7%), 22 patients (25%) required modified methods (12 using pulmonary vein and 10 using balloon). The modified method group had the larger size of ASDs and smaller posterosuperior rim. The mean ratios of the LA anteroposterior diameter, width, and length to the device size were all significantly smaller in the modified methods group than in the conventional group (1.20 vs. 1.56, 1.32 vs. 1.71, and 1.61 vs. 2.07, respectively). We found that the risk factors for the modified methods were smaller retroaortic rim, larger ASD, and smaller LA dimension/device size. CONCLUSION: In addition to larger defects and smaller retroaortic rim, the smaller ratios of the LA dimensions to the device size influenced the need for the application of modified methods in the transcatheter device closure of ASDs.
