Forty-five modified arthroscopic transglenoid suture capsulorrhaphy were performed between January 1989 and May 1995 with minimum follow-up of one year among sixty-four recurrent anterior shoulder instability in Chungnam National University Hostital. The average age at operation were 25 year and average time interval from injury to surgery were 12 month. we classify the Bankart lesion into 4 type according to the extent of capsulolabral complex detatchment, associated glenoid rim fracture, type II SLAP lesion and absence of glenoid labrum. Type Ia have a separation of labrum and inferior glenohumeral ligament from the glenoid rim and scapular neck (classic Bankart lesion) and type IIa have a capsular separation and glenoid rim fracture. Type IIIa have above mentioned type Ia or type IIa with type II SLAP lesion and type IVa have capsular separation without identifiable labral structure. We also subdivided the each type into subgroup b according to coexistence of capsular laxity. We modify the capsular suture technique according to classification. Type Ia, and type IIa were treated with in situ Bankart repair. Type Ib and type IIb were treated with capsular advancement. Type IIIa and 1IIb were treated with Bankart repair and additional fixation of SLAP lesion. Type IVa and IVb were treated with purse string type suture (capsular shift superiorly) with multiple stitches. All patients had various shape of Bankart lesion, so author s proposed classification of the Bankart lesion can be applied to each type. Arthroscopic finding were as follows. Twelve shoulders (27%) have type Ia Bankart lesion and six patient (13%) have type lIa lesion. Type lIIa were observed in eight shoulders (18%) and four patient (9%) were type IVa. The capsular laxity (subgroup b) were found in 15 patient (33%). None of the 45 patients experienced intraoperative complications or infec tion. All patients had full, painless range of motion and had no recurrence except four patient. One is type IIIa Bankart lesion in which associated type II SLAP was not repaired and the other two patients had sport injury and one patient had severe retrauma on 2 years after operation. We conclude that Bankart lesion is the essential lesion of recurrent anterior shoulder instability and were founded in all cases of recurrent anterior shoulder instability, and modified athroscopic transglenoid suture capsulorrhaphy according to arthroscopic classification is safe and effective method with acceptable recurrence rate.

A randomized, prospective study was conducted between October, 1994 and April, 1996 to compare the efficacy and safety of warfarin (group I) with dextran (group II) for the prevention of DVT after hip arthroplasty. 109 cases in 106 patients were included in the study. There were 60 cases in group I and 49 cases in group IL Risk factor for DVT were analysed before surgery and prophylactic modalities were performed. Color doppler was performed to all patients by one muskuloskeletal radiologist on 5th 8th post operative day and on 6 weeks after operation. DVT occurred in ten ( 16.6% ) of the 60 patients in group I, six ( 12.2% ) of the 49 patients in group II. but, this difference was not significant ( p= 0.582 ). Statistical analysis for the risk factors of age, sex, operation time, anesthetic method and operation method were performed and there were no statistical difference. Only statistical significance was a higher rates of DVT in cemented hip arthroplasty (p=0.028). There were seven proximal thigh DVT and nine calf DVT. We confirmed with sequential color doppler image that all cases of DVT except two complicated cases were resolved within 8 weeks after treatment: one case was expired for the reason of PE, and the other case had thigh hematoma during the treatment with warfarin. We could detect only one case of late onset DVT.

Diseases of the peripheral nervous system are the most prevalent in patients with end-stage renal disease (ESRD). Although increased blood levels of lead in ESRD have been reported, the role of lead remains to be elucidated. The purpose of this study was to determine the connection of blood lead concentration with peripheral nerve conduction velocity. One hundred ninety-eight healthy subjects (control group) and 68 patients with ESRD undergoing hemodialysis (ESRD group) were enrolled. Nerve conduction was measured within two hours after hemodialysis. Orthodromic sensory nerve action potentials and compound muscle action potentials were recorded on the median, ulnar, and radial nerves. Hemoglobin-corrected blood lead was significantly higher in ESRD patients than in controls (9.1+/-2.8 microgram/dL vs. 5.9+/-2.3 microgram/dL, p<0.001). 32.4% of 68 ESRD patients with diabetes mellitus were significantly related to poorer motor and sensory nerve conduction velocity (p<0.001). However, blood lead was not a significant predictor of the nerve conduction velocity (p>0.05). Our result suggested that even though the blood lead levels were high in ESRD, they were not associated with the decline of peripheral nerve function. Diabetes mellitus is a primary independent risk of neuropathy in ESRD patients.

BACKGROUND/AIMS: The current study was designed to determine whether the indoor air pollution in a hemodialysis room (HD) was different from that of other comparable areas in a hospital. METHODS: Five air monitor samplers were hung on the ceiling and placed on the table in both the HD and general ward nursing stations, respectively. In addition, five samplers were placed in the nurse's breathing zone of the HD and the general ward, respectively. Ten air monitor samplers were also placed on the edge of the bed in the HD, which represented the patient's breathing zone. The levels of benzene and toluene were analyzed by GC/MS. RESULTS: In the general ward, the toluene concentration was significantly higher in the nurse breathing zone than that for the ceiling or table samples (p=0.001). The benzene concentration was also significantly higher in the general ward nurse breathing zone than that in the HD (p=0.006). In addition, the benzene concentrations on the table were higher at the general ward as compared to the HD (p=0.028), but there was no significant difference between the ceiling, general ward station and HD. CONCLUSIONS: Both the benzene and toluene concentrations in the HD appear to be more affected by the outdoor atmospheric conditions than by any potential indoor internal sources.

This study was designed to examine how such factors as hemodialysis parameters, body mass index, renin and aldosterone concentrations, sympathetic nervous activity, and parathyroid hormone concentrations are associated with the control of hypertension in hemodialysis patients. Hemodialysis patients (n=114) were grouped into four categories. Group 1 had normal BP without antihypertensive medication. Group 2 needed one antihypertensive drug, Group 3 needed combination of two or three categories of antihypertensive drugs without minoxidil. Group 4 needed more than three categories of antihypertensive drugs including minoxidil. Parathyroid hormone, beta2-microglobulin, renin and aldosterone, epinephrine, norepinephrine, and hemodialysis parameters were measured. The fractional clearance of urea as Kt/V urea was significantly lower in Group 3 and Group 4 than in Group 2 (p<0.01). Concentrations of parathyroid hormone were significantly higher in Group 4 than the other groups (p<0.01). Pre-hemodialysis norepinephrine concentrations were significantly higher in Group 4 than the other groups (p<0.05). Traditional factors associated with hypertension did not seem to be relevant to the degree of hypertension in hemodialysis patients in the present study. In conclusion, poor Kt/V urea, elevated parathyroid hormone concentrations, and elevated concentrations of plasma norepinephrine seemed to be the factors that might be associated with control of hypertension in hemodialysis patients.

BACKGROUND/AIMS: Many patients with acute paraquat (PQ) intoxication die even at low PQ concentrations, whereas others with similar concentrations recover. Therefore, it is possible that individual differences in antioxidant capacity are responsible for the variable clinical outcome in patients with acute PQ intoxication. METHODS: We investigated whether there was a relationship between the genetic polymorphisms of SOD (V16A), catalase (C262T), and GPX1 (C593T) in 62 patients with acute PQ intoxication and the clinical outcomes of these patients. RESULTS: The frequency of the Mn-SOD V/V, V/A, and A/A genotypes were 56.3, 43.5, and 0% in survivors and 86.9, 13.1, and 0% in non-survivors (p > 0.05). The GPX1 C/C, C/T, and T/T genotypes were present in 100, 0, and 0% of all subjects. The catalase C/C, C/T, and T/T genotypes were present in 100, 0, and 0% of survivors, and in 82.6, 17.4, and 0% of non-survivors. Neither erythrocyte SOD activity nor catalase activity were significantly different between survivors and non-survivors. CONCLUSIONS: No association was found between clinical outcome of acute PQ intoxication and the genetic polymorphism of GPX1 (C593T) or the genetic polymorphisms or enzyme activity of superoxide dismutase (V16A) or catalase (C262T).

Primary liver cancer has traditionally been classified as either hepatocellular carcinoma (HCC) or cholangiocarcinoma (CCC). However, primary liver cancer occasionally consists of elements from both HCC and CCC. Intermediate hepatic carcinoma and primary liver cancer of the intermediate type are extremely rare subtypes of primary liver cancer that show features intermediate between HCC and CCC. First reported in 1998, the clinical, radiologic, and histopathologic characteristics of this entity remain unclear. In this case report, we describe the clinical, magnetic resonance imaging, histopathological, and immunohistochemical findings in a patient with intermediate hepatic carcinoma who was initially thought to have intrahepatic cholangiocarcinoma.

BACKGROUND AND PURPOSE: Evaluating respiratory function is important in neuromuscular diseases. This study explored the reference ranges of the maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), and sniff nasal inspiratory pressure (SNIP) in healthy adults, and applied them to amyotrophic lateral sclerosis (ALS) patients. METHODS: MIP, MEP, and SNIP were measured in 67 healthy volunteers aged from 21 to 82 years. Reference ranges were evaluated by multivariate regression analysis using the generalized additive modeling of location, scale, and shape method. Thirty-six ALS patients were reviewed retrospectively, and abnormal values of MIP, MEP, and SNIP were determined according to the reference ranges. RESULTS: MIP, MEP, and SNIP were abnormal in 57.1%, 51.4%, and 25.7% of the ALS patients, respectively. MIP and SNIP were significantly correlated with the degree of restrictive pattern and respiratory symptoms. The ALS Functional Rating Scale-Revised score was correlated with SNIP. CONCLUSIONS: This study has provided the reference range of respiratory muscle strength in healthy adults. This range is suitable for evaluating respiratory function in ALS patients.

The presence of accessory scrotum is a condition characterized by additional scrotal tissue with a normally developed scrotum. The condition is extremely rare and can be associated with a perineal lipoma. Herein, a case of accessory scrotum associated with a perineal lipoma is reported in a 4-day-old boy. He presented with a perineal mass and the diagnosis was confirmed by surgical excision and subsequent histological analysis. This is the first Korean report of an accessory scrotum associated with perineal lipoma. (Korean J Urol 2007;48:1096-1098)

BACKGROUND/AIMS: The aim of this study was to investigate the mortality, bleeding control rate, and their associated predictors in patients treated with Sengstaken-Blakemore (SB) tube for uncontrolled variceal hemorrhage associated with hemodynamic instability or failure of endoscopic treatment. METHODS: The clinical data of 66 consecutive patients with uncontrolled variceal hemorrhage treated with SB tube at Gyeongsang National University Hospital from October 2010 to October 2015 were retrospectively analyzed. RESULTS: The overall success rate of initial hemostasis with SB tube was 75.8%, and the independent factors associated with hemostasis were non-intubated state before SB tube (odds ratio, 8.50; p = 0.007) and Child-Pugh score < 11 (odds ratio, 15.65; p = 0.022). Rebleeding rate after successful initial hemostasis with SB tube was 22.0%, and esophageal rupture occurred in 6.1%. Mortality within 30 days was 42.4%, and the related independent factors with mortality were failure of initial hemostasis with SB tube (hazard ratio, 6.24; p < 0.001) and endotracheal intubation before SB tube (hazard ratio, 2.81; p = 0.018). CONCLUSIONS: Since the era of endoscopic band ligation, SB tube might be a beneficial option as a temporary salvage treatment for uncontrolled variceal hemorrhage. However, rescue therapy had a high incidence of fatal complication and rebleeding.
