Medial dislocation of the long head of the biceps brachii is a rare condition that usually occurs in association with tears of the subscapularis, chronic impingement, capsular defects or a fracture of the lesser tuberosity. Less commonly, a biceps tendon dislocation may occur after an acute traumatic event. Following a dislocation, the biceps tendon will assume either an intra- or extra-articular position depending on whether or not the subscapularis tendon detaches from its humeral insertion. Magnetic resonance imaging has been found to provide valuable information concerning the location of the biceps tendon and the integrity of the subscapularis tendon. We present a patient with a traumatic dislocation of the biceps brachii tendon in which the diagnosis remained elusive for an extended period of time. In this case, he was evaluated using MRI and reconstruction was performed by restoring the tendon to its anatomical position.

Fractures of the scapula are relatively uncommon injuries and treatment in the vast majority of cases remains nonsurgical and the results have been quite satisfactory. But the scapular fracture itself may be neglected because of its high incidence of many kinds of associated injuries so its delayed treatment sometimes gives bad and unpredictable results. Although open reduction and internal fixation has been accepted as the treatment of choice for displaced intra-articular fractures in many anatomical regions, there has been no definite treatment principles of surgical indications and approaches in the glenohumeral joint. At our institution, II displaced intra-articular fractures of the glenohumeral joint were treated with open reduction and internal fixation from March 1993 to February 1997. This paper reports the results of treating 11 displaced intra­articular fractures of the glenoid by open reduction and internal fixation. There were 10 men and one woman and the fractures were classified according to Ideberg : Type Ⅰa(4), Type Ⅱ(3), Type Ⅲ(1), Type IV(1), Type Va(1), and Type Vc(1).

We treated 5 elbows with post-traumatic flexion contractures (mean contracture: 51 degrees) by arthroscopic anterior capsular release and post-operative alternative flexion and extension splint. Each elbow had been resistant to at least six months of conservative therapy. An incongruent ulno-humeral articulation was considered to be a contraindication to this procedure. All patients complained of the residual deformity and some functional deficit. All patients, after failure of non-operative therapy, desired a operative treatment. At follow-up(mean 21.8 months), there was a mean post-operative contracture of 19 degrees, which is within a functional range of motion. So we conclude that arthroscopic capsular release in selected patients is reasonable alternative to open release.

Anticonvulsant hypersensitivity syndrome is a rare but fatal complication. It manifests as fever, skin rash, lymphadenopathy, and hepatitis. Phenytoin, phenobarbital, and carbamazepine are the most frequently involved drugs. We here report a case of phenytoin-induced anticonvulsant hypersensitivity syndrome. A 37-year-old woman presented with fever and generalized skin rash, 3 weeks following commencement of phenytoin 400mg daily for treatment of seizure after superficial temporal artery-middle cerebral artery(STA-MCA) anastomosis for moyamoya disease. Her temperature was $39.3^{\circ}C$ and her face was edematous. Laboratory findings showed elevated hepatic enzymes and eosinophilia. Blood and urine culture were all negative. Initially, prednisolone was commenced at 30 mg daily. But fever and skin rash did not improved and hepatic function was more aggravated. After increasing dose of steroid(methylprednisolone 125mg/day), fever and skin rash disappeared and hepatic enzymes returned to normal range.

Recently various operative procedures including microsurgery or endovascular surgery have been increasing for the management of ischemic cerebrovascular diseases. Carotid endarterectomy(CEA), extracranial-intracranial(EC-IC) arterial bypass, embolectomy, decompressive craniectomy, arterial transposition, intravascular thrombolysis, and percutaneous transarterial angioplasty and stenting (PTAS) are available surgical modalities for ischemic stroke. This article focuses the complications and perioperative management of patients treated with CEA and carotid PTAS among various surgical managements for ischemic stroke.

From May 1994 to May 1995, we performed a prospective controlled double-blind clinical study of 85 patients(85 shoulders). For inclusion in the study all patients met the following criteria: 1) a diagnosis of impingement syndrome by lidocaine injection test; 2) symptoms for at least three months; 3) no previous subacromial injection; 4) no evidence of rotator cuff tear. We excluded the patients from the study who showed a instability or other clear primary cause. The patients were randomized to receive either 5/subcc/ 2% lidocaine with 4ee of 20mg/cc Depomedrol(Group 1) in 45 cases or 5/subcc/ 2% lidocaine solely(Group 2) in 40 cases. At three month follow-up, all results were better in steroid group than control group. But at one year, improvement of pain and daily activity showed no difference between two groups. So we conclude that the use of subacromial steroid injection is effective for short-term therapy in the treatment of subacromial impingement syndrome, but the long-term effectiveness is doubtful.

We present a modified method for the treatment of brain abscess. The double lumen extraventricular drainage (EVD) catheter which was developed for the intracerebral hematoma management, was applied for the treatment of brain abscess drainage. We placed the double lumen EVD catheter into the abscess cavity by free-hand technique and irrigated the abscess cavity continuously with antibiotics solution for 7 days. Simultaneous intravenous antibiotics was administered for 4 weeks. The continuous irrigation with double lumen catheter was found to be safe and effective treatment modality in the brain abscess.

Neurological symptoms may develope when the blood urea nitrogen is lowered too rapidly by hemodialysis. It is known that these symptoms, known as dialysis disequilibrium are associated with cerebral edema. However, the pathogenesis of brain swelling and neurological deterioration after rapid hemodialysis is controversial. The reverse urea hypothesis suggests that hemodialysis removes urea more slowly from the brain than from the plasma, creating an osmotic gradient that results in cerebral edema. The idiogenic osmole hypothesis proposes that an osmotic gradient between brain and plasma develops during rapid dialysis because of newly formed brain osmoles. Authors report a such case and discuss the possible mechanism and preventive methods.

Splenic rupture is a frequent surgical emergency in blunt abdominal trauma patients. There are several treatment options, including conservative treatment, a partial splenectomy, splenorrhaphy, and a splenectomy for splenic injury. Although reports on the safety and the efficacy of an elective laparoscopic splenectomy are abundant in the literature, a laparoscopic splenectomy for a ruptured spleen has only been reported in a few cases. We report a case of a laparoscopic splenectomy in the patient with Grade III traumatic splenic injury. To our knowledge, this is the first report in which a laparoscopic splenectomy was performed in Korea for the treatment of a traumatic splenic injury.

We present two cases of deep cerebral venous thrombosis(DCVT) with the totally occluded straight sinus. A 42-year-old female received with altered mentality . She has taken antihistamine for six years to treat the paranasal sinusitis. Another 34-year-old female who used the oral contraceptive for 11 months presented with acute behavior change . Both of these patients were diagnosed by computed tomography(CT), magnetic resonance(MR) imaging, and cerebral angiography. They were fully recovered with systemic urokinase thrombolysis followed by heparin therapy. We report that the intravenous thrombolysis was potentially effective management strategy in our cases of DCVT with the totally occluded straight sinus.
