A relationship between preceding acute paralytic poliomyelitis and the later development of motor neuron disease has only occasionally been suggested since it was first postulated by Charcot in 1875. The authors recently experienced a 20-year-old male who was considered to have postpoliomyelitis muscular atrophy. We report this case in view of its rarity and necessity of differential diagnosis from other neuromuscular disorders. Clinical presentation included slowly progressive muscle wasting of left thigh for 4 years, mild weakness of left arm and both thigh, intermittent fasciculation, and previous history of acute paralytic poliomyelitis. Electromyographic findings showed fibrillation potentials, positive sharp waves, fasciculations, giant motor unit potentials and reduced interference patterns. Muscle biopsy revealed scattered small angulated fibers, individual myofiber degeneration and mild inflammatory cell infiltration.

Congenital dislocation of the knee is very rare skeletal deformity and was firstly described by Chatelaine in 1822. Since then there have been a few number of case reports and some series discussing the etiology and treatment. The tibia is displaced anteriorly in relation to the femur. It is generally subdassified as simple hyperextention, subluxation, and dislocation depending on the degree of the joint displacement and the severity of disease. Early gentle manipulation and serial splintage or plaster cast are recommended for treatment and were successful in the majority except the case of quadriceps contrarture or late correction. The authors experienced one case of congenital dislocation of the right knee and brief review of the related literatures was made.

During the arthroscopic surgery of the shoulder, there was extravasation of fluid into the surrounding soft tissue due to the use of pressure pump irrigator. Clinically, the shoulder region became tense and intramuscular pressure of the deltoid could be elevated. To analyze the change of the intramuscular pressure of the deltoid and the efficiency of cryotherapy in the shoulder arthroscopy with pressure pump, we studied 35 consecutive patients who underwent various arthroscopic shoulder procedures at the Dankook University Hospital. We monitored intramuscular pressure using spinal needle connected to the patient monitoring system during arthroscopic procedures and postoperative period until return to preoperative pressure level. Twenty-seven patients were fitted with a cryotherapy. device in the operating room, and 8 were not according to the patient opinions. We evaluated the effect of cryotherapy with visual analog scales and amounts of analgisics for 3 days postoperatively. The results were followed; 1. Intraoperative highest intramuscular deltoid pressure was 293mmHg (average 169+/-68mmHg, 71293mmHg). 2. Immediate postoperative deltoid pressure was average 58.3+/-28.1mmHg (24-145mmHg). 3. Average time that the pressure had returned to the preoperative level was 114.3+/-38.6 minutes (p<0.05). There were no statistically significant between two groups, 113.9+/-41.1 min in the cryotherapy group and 115.7+/-32.6 min in the non-cryotherapy group. 4. Shoulder pain was less in the cryotherapy cases until second postoperative day. In conclusion, arthroscopic surgery of the shoulder can be performed with minimal complication in spite of high intramuscular deltoid pressure. More than 60 minutes may be needed for returning to normal intramuscular deltoid pressure. Cryotherapy is eftective in the pain relief but cannot minimize swelling postoperatively.

Remarkable advances have been made recently in the area of liver regeneration. Even though liver regeneration after liver resection has been widely researched, new clinical applications have provided a better understanding of the process. Hepatic damage induces a process of regeneration that rarely occurs in normal undamaged liver. Many studies have concentrated on the mechanism of hepatocyte regeneration following liver damage. High mortality is usual in patients with terminal liver failure. Patients die when the regenerative process is unable to balance loss due to liver damage. During disease progression, cellular adaptations take place and the organ microenvironment changes. Portal vein embolization and the associating liver partition and portal vein ligation for staged hepatectomy are relatively recent techniques exploiting the remarkable progress in understanding liver regeneration. Living donor liver transplantation is one of the most significant clinical outcomes of research on liver regeneration. Another major clinical field involving liver regeneration is cell therapy using adult stem cells. The aim of this article is to provide an outline of the clinical approaches being undertaken to examine regeneration in liver diseases.

Mazabraud's syndrome is rare benign disease characterized by the association of intramuscular myxoma and fibrous dysplasia of bone. We present a case of multiple intramuscular myxomas of the right forearm with polyostotic fibrous dysplasia. X-rays suggested fibrous dysplasia of adjacent bones and CT scans showed two intramuscular cystic masses on the right forearm. 99mTc bone scintigraphy also showed a markedly increased uptake in the skull, both scapulas, both clavicles and both humeri. The masses were successfully removed. Fibrous dysplasia of the radius and myxoma were confirmed by pathologic study.

Open fractures of the tibial shaft have a high incidence of complication and often result in poor outcomes. The most common method of stabilization is the external fixation by way of the Ilizarov method but the small diameter interlocking intramedullary nailing has also been introduced. The purpose of this study is to analyze the result of Ilizarov method and to compare its results with those of delayed intramedullary nailing used in the treatment of open tibial shaft fractures. We analyzed 81 patients with open tibial shaft fractures, treated using Ilizarov external fixator, or by delayed locked intramedullary nailing between January 1987 and December 1994. The follow-up period was an average 14.5 months. Out of the 81 patients, 58 patients were treated by nails and 23 patients by Ilizarov external fixators. Both groups were given the same initial management but the operation of the nailing group was delayed until proper soft tissue coverage and healing of the wound were evident. In the Ilizarov method group, 58 fractures obtained union within 26 to 53 weeks (average of 32.8 weeks) and in the nailing group, 23 fractures showed union within 14 to 51 weeks (average of 21.2 weeks). There was a significant difference between the two groups (P<0.05). Complications in the Ilizarov group included 4 nonunions, 12 delayed unions, 3 malalignments, 14 wound infections and 13 stiff ankles. There were no nonunion, 10 delayed unions, 8 malalignments, 6 wound infections and 11 stiff ankles in the nailing group. In this study, the Ilizarov group had more delayed unions and nonunions took a longer period of time to obtain the union, and had a more limited range of motion in the ankle, than the nailing group. The nailing group was easier to manage, especially in the soft tis-sue procedure, and it did not require a high level of compliance while having a relatively low risk of malunion.

The common bile duct normally enters the posteromedial aspect of the second part of the duodenum. However, anomalous drainage of the common bile duct into the stomach, pyloric channel, duodenal bulb and fourth portion of the duodenum has been reported in the literature. An anomalous pancreatic duct, with ectopic drainage of the common bile duct, is particularly rare. Herein, we report the case of a 69-year-old woman who showed pancreatic ductal variation and anomalous drainage of the common bile duct into the duodenal bulb. The patient required a cholecystectomy and choledochoenteric anastomosis to relieve the obstructive jaundice and abdominal pain.

Duodenal gastrointestinal stromal tumors (GISTs) are relatively rare tumors that commonly present with gastrointestinal bleeding. Evaluation with endoscopic ultrasonography (EUS) is a useful technique for the differential diagnosis of GISTs from other submucosal tumors. A 58-year-old man presented with melena and anemia. An esophago-gastroduodenoscopy showed the presence of a submucosal tumor in the second portion of the duodenum with central ulceration and a flat spot. EUS showed the presence of a suspicious malignant GIST that originated from the proper muscle layer, which was successfully resected. We report a case of a duodenal GIST with a bleeding ulcer. Positive reactivity for CD117 and S-100 was demonstrated by immunohistochemical staining.
