On the length, strength, free lateral motion, and perfect mobility of the thumb, depends the power of the human hand. The thumb is called pollex because of its strength and that strength is necessary to the power of the hand being equal to that of all the fingers."So stated Sir Chales Bell in the fourth Bridgewater Treatise, first published in 1833. Morrison and O'Brien advocated reconstruction of the thumb with a free wrap around flap from the big toe to recreate a stable, sensate and functional digit including the nail in 1980. From March, 1982 to July, 1988, Twelve thumb reconstructions were performed using the wrap around procedure at Hanyang University Hospital;12 successful thumb reconstructions were reviewed at an average of 16 months after surgery. There were several complications;these included skin necrosis(4), malunion(1), resorption of the bone graft(7). We considered that cosmesis and function were good;pinch grip averaged 68% of normal, sensibility returned in all patients as assessed by two-point discrimination(average 9.5mm). Over all the results are as follows. 1. The wrap around technic provides a good method of reconstruction. 2. The wrap around technic is one stage operation and can be used in the level of metacarpal amputation. 3. The surgeon should be familiar with microsurgical technic.

Pseudolipomatosis of the colonic mucosa has been recognized as a lesion featured with aggregations of gaseous spaces in the lamina propria, but its pathogenesis remains still unclear. This paper describes 6 cases of pseudolipomatosis occurring in the mucosa of stomach and large intestine, and the possible factors involved in gastrointestinal endoscopic procedure to produce gaseous entrapment in the lamina propria were analysed. All cases received either gastroscopy or colonoscpy before endoscopic biopsy. Mucosal tissues from both stomach and recto-sigmoid colon revealed multiple aggregations of small air-spaces resembling fatty infiltration in the lamina propria. Rarely were similar infiltrations within the muscularis mucosae and adjacent lymphoid follicles. Evidence for pneumatosis cystoides intestinalis or ulcerative colonic lesion was not associated, although one showed a small gastric ulcer nearby. Repeated inflations and deflations of the stomach or colon during the endoscopic procedure with miner mechanical trauma by instrument to the mucosa seem to contribute to its pathogenesis.

Granular cell tumor(GCT) has been identified in all organ systems, most often in the oral cavity and subcutaneous tissue. GCT of the esophagus has been considered rare. However, this neoplasm is being recognized with increased frequency since the use of fiberoptic endoscopy has become widespread. We report 5 cases of granular cell tumors involving the esophagus, all of which were incidentally found. Four additional cases of GCT which appeared in the Korean literature were reviewed.

The present study reports two cases of femoral component fracture using Whiteside Ortholoc prosthesis(Dow Corning Wright, Arlington, Tennessee) with cement. The causes of the fracture were investigated by radiological findings, prosthetic design and metallurgical study using scanning electron microscope(SEM) and energy dispersive spectrometer(EDS). Respectively, the findings from this study are summarized as follows. In X-ray study, one case had valgus 3 mechanical axis(normal: valgus 7 axis) while the other case had 10 tibial anterior slope(normal: 10 posterior slope). The medial side of femoral component fractured in both cases. The fracture site was in the junction between the posterior bevel and distal surface of the medial side of femoral component. The analysis of the prosthetic design showed that the Whiteside Ortholoc femoral stem was thinner, and shorter at the site of posterior bevel surface of the femoral stem than other TKA(Total Knee Arthroplasty) system. The metallurgical study by SEM showed that the crack was developed initially near the inner surface of fractured femoral component and was extended to the outer surface. Carbon particles were detected in the fractured femoral component by EDS. The findings imply that operating technique is very important especially during bone cutting and soft tissue balance in TKA. It is also proposed from this study that a minor design modification such as a thicker and longer Whiteside Ortholoc femoral component would be better and that the cast-iron ware of TKA system has to he produced by careful metallurgical process, that precludes the incorporation of any foreign material such as carbon particles.

Percutaneous needle aspiration biopsy (PNAB) of suspected pulmonary malignancy is a simple, safe and practicalmethod, so should be used earlier and moe frequently to shorten the diagnostic interval. In Korea Cancer CenterHospital, 64 patients underwent PNAB with a diagnotic yield of 87.5%. 7 patients and a pneumothorax and in 3patients developed transient hemoptysis. Of 58 malignant of no

Recent immunological investigations have demonstrated that the patients with psoriasis have various humoral and cellular immune abnormalities, such as increased serum IgG, IgE and secretory IgA, anti-IgC factor in psoriatic lesions, in peripheral blood lymphocytes and in serum, rhumatoid-like factors in IgA and IgG classes of immunoglobulins, antinuclear antibodies (ANA; reacting with the basal cell nuclei of uninvolved skin., anti-stratum corneum antibody and complements in psoriatic scales, immuoglobulin and complement bearing polymorphonuclear leucocytes in the Muro microabscess. These abnormal findings are enough to suggest an autoimmune mechanism in the pathogenesis of psoriasis. Several investigators have also reported the results of T cell enumeration in the peripheral blood in psoriatic patients. However, the results are not in general agreement,. Thee present study was undertaken to clarify any abnormality in the proportion of T cells in the peripheral blood in psoriatic patients. Forty-one patients with active psoriasis registered at the Department of Dermatology, Seoul National University Hospital entered this study from May, 1979 through April, 1980. Twelve healthy medical and paramedical personel the comprised the control group. Active and total T cells were enumerated by the method of E-rosetting technique, and the results were as follows. 1, in normal controls, the active and total T celIs identified as E rosetteforming cells accounted for 61.6+7.4% and 68.1+8.9% of the total lymphocyte population, respectively. 2. In patients with psoriasis, significant decrease of active T cells (54. 2,+11.0%,p<0.005) and total T cells (62.2+11.2%, p<0.05) was observed. More profound reduction of T cells was noted in patients with wide spread psoriasis than those with limited extent.

OBJECTIVES: From February 1995 to April 1998, those patients who had visited for evaluation of infertility, shown abnormal endometrial pattern on hysterosalpingography underwent resectoscopic operation. We evaluated about its therapeutic effect, recurrence rate of uterine adhesion and effectiveness of its assisted method. METHOD: We have reviewed 45 cases of intrauterine adhesion, classified as a central type, marginal type and multiple type. We used 26F resectoscope made in Storz for operation and inserted Lippes loop or pediatric foley catheter for prevention of readhesion. For promoting reepithelialization, conjugated estrogens(premarin) 5mg daily for 30 - 50 days were given and then 10mg of medroxyprogesterone acetate(provera) were added daily for the last 10 days. We evaluated the uterine cavity condition preoperatively and postoperatively by using hysterosalpingography. RESULT: In 45 cases, 41 cases were followed up postoperatively. 21 cases were markedly improved, 12 cases were improved and 8 cases were not improved or recurred on hysterosalpingography. In 41 cases, for prevention of readhesion 20 cases were used pediatric foley catheter and 5 cases(25%) were recurred. 21 cases were used Lippes loop and 3 cases(14%) were recurred. Pregnancy outcome was as follows;15 cases were pregnant and 10 cases delivered a viable infant, 3 cases aborted spontaneously, 1 case was ectopic pregnancy and laparoscopic salpingectomy was done, 1 case was ongoing pregnancy. CONCLUSION: This report suggests that resectoscopic operation is very effective in the treatment of intrauterine adhesion(therapeutic rate of 81%) and that the use of Lippes loop seems like to have the less recurrence rate than the use of pediatric foley catheter in prevention of postoperative readhesion, but more experience and further follow-up are necessary to obtain more detailed conclusions.
