The provision of adequate soft tissue cover for a complex hand and forearm wound-dirty, infected and exposed bone can be a challenging problem. Conventionally, a distant flap or free flap have been used, but these have been associated with several problems such as joint stiffness, risk of microsurgical procedures, negligible donor site morbidity, prolonged operation time and economic restriction. As well, fasciocutaneous flap has been the limitation of infection control. In these situations, the ipsilateral muscle flap provides the ideal cover with its rich blood supply and single operative field. Previously described by Lendrum(1980), by Lae et al.(1981), and later by McGeorge(1991), the brachioradilis muscle is the most superficial muscle on the radial side of the forearm. Its flap is based on the radial artery and venae comitantes. From August 1996 to October 1997, we performed branchioradialis muscle flap in seven patients. Despite the sacrifice of the major hand artery, brachioradialis muscle flap has many advantages including the reliability of flap survival, easy dissection, early mobilization and absence of functional and aesthetic problems at the donor site. It is a relatively simple and rapid method for resurfacing soft tissue defect in the hand and forearm. We obtained satisfactory and reliable results.

A preliminary study was conducted to evaluate the immediate postoperative recovery and socioeconomic efficacy with the surgical release of Carpal tunnel syndrome by double incision technique. Sixty cases of carpal tunnel syndrome were operated by one surgeon between 1993 and 1995 and 44 cases in 39 patients were available for this study. Surgery was done under axillary block and patients were evaiuated preoperatively, 3 weeks and 6 weeks each postoperatively. The evaluation was focused on the immediate recovery in terms of subjective symptoms of pain and paresthesia, local tenderness, strength of grip power and pinch power and postoperative disability. 1l was noted that surgical release of carpal tunnel syndrome utilizing double incision technique was as effective as seen in the endoscopic release in terms of quicker recovery of pain, local tenderness and strength. It was also noted that this double incision technique was as safe and economically beneficial as observed in the conventional open procedure.

The t(3;21) (q26;q22) is associated with chronic myelogenous leukemia in blast crisis, leukemia evolving from therapy-related myelodysplasia, and with leukemia following other hematopoietic proliferative diseases. The t(3;21) is rare secondary aberration in blast crisis of Philadelphia(Ph)-positive chronic myeloid leukemia, which may be restricted to patients entering myeloid blast crisis. We report here in one case of chronic myeloid leukemia in blast crisis which reveals both t(9;22) (q34;q11), and t(3;21) (q26 ;q22). A 62-year-old male was diagnosed as chronic myeloid leukemia 5 years ago, received hydroxyurea therapy, and admitted because of gingival bleeding and fever. On examination, splenomegaly and leukocytosis with proliferated blasts(91%) in peripheral blood were noted. Bone marrow aspirate showed hypercellularity with severe blast proliferation(92.5%) which revealed all negative in peroxidase and PAS stain. Cytogenetic study of bone marrow cells showed the karyotype 46, XY, t(3;21) (q26;q22), t(9;22) (q34;q11), which might be suspected as myeloid blast crisis. Above finding was confirmed by the result of immunophenotyping(CD13 43.6%, CD34 68.2%, HLA-DR 91.6%). He received intensive chemotherapy, but still sustained proliferation of blasts was noted . The follow up cytogenetic study was as follows: 46, XY, 4(3;21) (q26:22), t(9;22) (q34;q11)/46, XY, t(3;21)(q26;q22), del(8) (q22), t(9:22) (q34,q11)/46, XY (16/3/1). He died soon from severe pancytopenia and sepsis.

A rare case of traumatic bilateral anterior and posterior dislocstions of the hip wss occured by autamobile accident as a passenger injury. The right hip was dislocated anteroinferior to the righ scetabulum(neer the right obturator froamen), and the left hip was dislocated posterosuperior to the left acetsbulum with a ipsilateral femur head fracture caudsd to the fovea centralis(Fig. 1).

The sclerotium of Poria cocos Wolf, which grows on the roots of pine trees, has long been used as a sedative and diuretic (Chang and But, 1987). The accumulating data revealed that certain ingredients of the sclerotium of Poria cocos showed anti-tumor activities (Kanayama, 1986). Although the mechanism of anti-tumor activity is not known, the polysaccharides may potentiate the host defense mechanism through the activation of immune system. In the present study we show that PCSC22, a polysaccharide isolated from the sclerotium of Poria cocos with one percent sodium carbonate, significantly induces nitric oxide (NO) production and inducible NO synthase (iNOS) transcription. To further investigate the mechanism responsible for the induction of iNOS gene expression, we investigated the effect of PCSC22 on the activation of NF-kappaB/Rel, whose binding site was located in the promoter of iNOS gene. Immuno-histo-chemical staining of p65 and p50 showed that PCSC22 produced strong induction of NF-kappaB/Rel nuclear translocation. Electrophoretic mobility shift assay (EMSA) further confirmed the activation of NF-kappaB/Rel by PCSC22. In conclusion, we demonstrate that PCSC22 stimulates macrophages to express iNOS gene through the activation of NF-kappa B/Rel.

We report a case of subclavian artery laceration caused by the removal of a pigtail pleural drainage catheter in a patient with a pneumothorax. The patient was successfully resuscitated through diagnostic angiography with subsequent balloon occlusion and primary repair of the injured subclavian artery. Although pigtail drainage of a pneumothorax is known to be safe and effective, proper insertion and removal techniques should be emphasized to reduce the risk of complications.

The purpose of this study was to compare surface roughness and bone formation around two types of threaded commercially pure titanium implants manufactured by two different companies. The test implants were manufactured by Sumin synthesis dental materials Co. (Avana, Busan, Korea), while the controls were manufactured by Nobel Biocare (MK II, Goteborg, Sweden). To compare bone formation adjacent to newly product with Branemark MK II implant, surface roughness was measured by Accurate 1500M and histomorphometric analysis was done. The results were as follows : 1. Measurement of surface roughness showed that Avana implant had a slightly more irregular surface compared with Branemark implant. 2. In the light microscopic studies, no infiltration of inflammatory cells nor the giant cells wee observed on both groups. 3. In th light and fluorescent microscopic studies, the amount of osseointegration and the extent and the timing of bone formation were similar. 4. There were no statistically difference between two groups in the average bone to implant contacts. Branemark implant ; 67%(SC 23%), Avana implant ; 70%(SD 16%). Comparing with Branemark implant, Avana implant made of CP grade II titanium showed similar good bone healing, formation and osseointegration.
