Acquired digital fibrokeratoma is an uncommon, solitary, round, firm, more or less hyperkeratotic projection, most frequently situated on fingers or toes but occasionally on the other locations. It arises out of a collarette of slightly raised skin and may have slight or great resemblance to a rudimentary supernumerary digit or may be mistaken for some other more ordinary condition such as an odd cutareous horn. We experienced a case of acquired digital fibrokeratoma on the right second finger in a 25-year-old male. We treated it with total excision.

Eccrine spiradenoma is clinically characterized by a solitary, movable, tender noduie occurring most frequently on the ventral surfase of the upper body. A striking symptom is paroxysmal pain. Histopathologically, the encapsulated lobules of the tumor are composed of masses of basophilic cells, usually arranged in whorls, cords, and pseudogland.s. Within the whorls and pseudoglands, two types of celIs are notedperipheral intensely staining cells and central pale-staining cells. We describe herein a patient with an indolent eccrine spiradenoma, which had been diagnosed histopathologically.

We performed this study to observe the effects of chronic administration of leuprolide acetate(potent synthetic LHRH analog) to the testicular histopathology of prostatic cancer patient and to the spermatogenesis in cryptochism treatment. Ten out of fifty healthy male rats whose body weight ranged 250-300gm were selected as a control group and the other forty as a study group. Two hundred micro-gram of leuprolide acetate was injected daily into the peritoneal cavity of study group, and ten rats were sacrificed at each first, second, third and sixth week, respectively. Then the changes of testicular weight and histopathological readings under light microscope of both control and study group were recorded and analyzed. The results of experimental data can be summarized as follows : 1. The average testicular weight of control group increased progressively until sixth week to 1. 1.43gm from the initial value of 1.26gm, while the weight of study group decreased to 0.96gm which was 67.1 % of age-matched control group. 2. There were almost no remarkable changes between both groups in terms of number, size and cellularity of seminiferous tubules. We observed the degenerative and regenerative changes simultaneously in spermatogonia and spermatocytes. During the first three weeks, degenerative changes took place while the regenerative changes started from the second week and have fully recovered at the sixth week. And, the number of spermatids and spermatozoa slightly decreased at the first week, but have recovered to normal value from the second week. 3. There were noticeable changes neither in the interstitium of testes except the minimal edema nor in terms of size and number of Leydig cell. The results using rats showed the discordance with those of human study of prostatic cancer patient. This conflict can be attributed to the functional differences of leuprolide action between two species, age of sacrificed rats and insufficiency of dose and time of administration. However, we can draw another conclusion that the leuprolide acetate is expected to have no significant adverse effects to the spermatogenesis in cryptorchism treatment.

Ureteroscopic removal of stone is now an established technique for the management of ureteral stones and can be done under direct vision using flexible grasping forceps or stone baskets with increased safety and efficacy. A clinical study of our 35 cases of ureteroscopic removal of ureteral calculi was performed. Only one among 4 cases of mid and upper ureteral calculi and 27 among 31 cases of lower ureteral calculi were removed successfully. Therefore the overall success rate was 80 %(28 among 35 cases). Complications occurred in 6 cases : a case of ureteral avulsion, a case of ureteral separation, 2 cases of uncomplicated urinary tract infection and 2 cases of ureteral perforations. We conclude that ureteroscopic removal of ureteral stone under direct vision can be done safely and be the first choice of management for the lower ureteral surgical calculi, but the antegrade removal of stone through percutaneous nephrostomy tract may be preferable for the upper and mid ureteral calculi.

27 Colles' fracture were treated with closed reduction and percutaneous k-wire fixation under the C-arm fields, from July 1980 to September 1984 at the Department of Orthopedic Surgery of Eul Ji Hospital. The average duration of the follow up was 4.9 Months. A prospective study was made and evaluated under the subjective and objective criteria of Gartland and Werley, and the objective criteria of Scheck. The results of this study were as follows: 1. The incidence was high in 4th and 5th decade as 66. 5%, not significant between females and males, 45% of the cause of injury was falling accident. 2. In 27 cases, showed the satisfactory result about 92.6%, but, in the eomminuted intraarticular fracture group, 2(15.4%) out of 13 cases showed unsatisfactory result. 3. Better result was obtained with more secure reduction and skillful technique, in certain case, considered that the open reduction and internal fixation with k-wires would be better than percutaneous k-wire fixation. 4. In the aspect of hand motion and the concept of improved anatomical restoration and maintenance would lead to improved function, ideal method was percutaneous k-wire fixation and casting after closed reduction under the C-arm fields.

The onset of systemic scleroderma in the first. decade of lif occurs in less than 1.5% of instances. Systemic sclerodrma in childhood have been characterized by less severe visceral involvement and a benign course We report a boy, aged 7 years, with a history of Raynaid; phenomenon and dysphagia. He had a mask-like face, flexion contracture of hands and knee joints, digital pitting scars, ichthyosiform skin change on leg and hyperpigrnented induration on all extremities and trunk. Antinuclear antibodies were positive in nucleolar type and Scl-70 antiocy was also present. On radiologie study, the pattern of reflux esophagitis and resorption of the listal ends of all phalanges were nated. Histopathological findings were compatible with sclerodma. He was treated with Penicillamine-D and oral corticosteroic with good improvernent.

BACKGROUND: Tufted angioma is an uncommon slowly progressive vascular tumor found typically in infants and young children with characteristic histologic findings, so called "cannonball" appearance. OBJECTIVE: The purpose of this study was aimed to investigate the clinical and histopathological characteristics of tufted angioma and the response to intralesional steroid. METHODS: Clinical information of 10 patients with tufted angioma diagnosed in Severance hospital and Pundang CHA hospital from 1983 to 1999 was obtained from the medical records and clinical follow-ups. We re-evaluated 10 biopsy specimens obtained from them with routine H&E staining. RESULTS: Five male and five female patients were included. In 9 patients the lesion appeared before 2 months of age. Four had a lesion at birth. The thigh was the most common site. The clinical symptoms were diverse, but characteristically tenderness was present in most cases. In all the patients the lesions had a tendency to spread progressively. Microscopically, numerous, distinct, variably sized, tightly packed capillary and endothelial cellular lobules were scattered in the dermis. There were characteristic semilunar spaces adjacent to the capillary tufts. Six patients received intralesional triamcinolone. This treatment was found to be effective in 5 patients who experienced remarkable improvement. The improved cases had similar histologic findings which were composed of cellular mass more than lumen formation. We classified our specimens into two categories, one with more cellular mass and the other with more lumen formation in relative proportion. The former was different from the latter in that it had more solid appearance and more definite margin. And we realized that it was useful to divide into these two categories since its response to treatment could be different. CONCLUSIONS: Tufted angioma is a relatively uncommon disease with characteristic histopathologic findings. It seems not to regress spontaneously. So early treatment is required to pre-vent further spreading up to the extent. We treated 6 patients with intralesional injection of triamcinolone and 5 patients experienced marked improvement which had more cellular mass more than lumen formation histopathologically.

The orbitozygomatic area occupies a key anatomic position in midface, is prone to injury, and plays a prominent role in facial aesthetics. So the facial appearance including orbital shape can be altered by complications of orbitozygomatic fractures. Most possible initial complications include blindness, hyphema, retinal detatchment, and paralysis or entrapment of extraocular muscles. Long term sequelaes include infraorbital nerve dysfunction, loss of malar projection, enophthalmos, and dystopia. Accurate anatomic reduction and rigid fixation is essential for management of orbitozygomatic fractures to minimize those late sequelaes. Conventional fixation devices to fix displaced fracture of facial bone are interosseous wire and miniplate. But interosseous wirings are unstable for primary bone healing and time consuming. Miniplates have great deal in rigid fixation but their high profile and palpability are the main complaints in many patients, especially in orbital rim area. In this article, we reviewed the 30 cases of zygomamaxilla complex fractures with orbital rim fracture fixed with microplates, and discussed the stability of microplate and superiorities in final aesthetics result. The use of microplates in these area permits enough stability of fracture segment with ease of procedures and superiorities in final results without any palpability.

BACKGROUND: Recent studies revealed that inhalational anesthetics (IA) attenuate NO production. But the hemodynamic changes produced by IA in septic syndrome patient are still sufficient to threaten patient, surgeon and anesthesiologist. So we examined which IA is proper to maintain vascular contractile force and evaluated the effects of NOS inhibitors on contractile force of septic rat aorta under IA. METHODS: Aortic ring preparation was obtained from LPS-treated (1.5 mg/kg, i.p. for 18h) rats. The development of sepsis was confirmed by iNOS activity and iNOS expression using RT-PCR. Contractile responses of aorta to phenylephrine admministation in the presence or absence of halothane, enflurane and isoflurane were evaluated. We also evaluated the effects of NOS inhibitors, one is NG-nitro-L-arginine methyl ester (L-NAME) and the other is aminoguanidine. Statistical significances (p<0.05) were analyzed according to data characteristics by unpaired t-test and paired t-test. RESULTS: The contractile responses to phenylephrine admministration were attenuated in LPS-treated rings. Isoflurane, even at the dose of 2 MAC, didn't affect the contractile response while both halothane and enflurane decreased the contractile response even at the dose of 1 MAC. The potentiation of contractile responses by NOS inhibitors were not affected during administeration of IA. CONCLUSIONS: From these results, it is suggested that isoflurane is the safest inhalational anesthetic and NOS inhibitors, especially L-NAME, may be very useful in the therapy of septic shock patients during general anesthesia.

BACKGROUND: Hepatitis B vaccination schedule commonly used in Korea is divided largely into 0, 1, 2 month scheduled vaccination group(0, 1, 2 group) and 0, 1, 6 month scheduled vaccination gorup(0, 1, 6 group). The only difference bet.ween two groups is the interval from 2nd dose to 3rd dose. This st,udy had been carried out, to find whether t.he difference of vaccination interval influence the vaccination complet,ion rate or not. METHODS: Study objects are 135 persons over 20 years old who had heptitis B vaccination more than once in injection room of Dongkuk University Kyong-ju Hospital from Jan. 1st in 1996 to Dec. 31th in 1996. Data about vaccination completion were gathered from record book of injection room and telephone interview. RESULTS: Hepatitis B vaccination completion rate is 73.8% in 0, 1, 2 group and 72.5% in 0, 1, 6 group. The reasons for incomplete vaccination are forgetting vaccinat.ion date(36.4% in 0, 1, 2 group and 50% in 0, 1, 6 group), having no time to spare for vaccination(54.5% in 0, 1, 2 group and 43% in 0, 1, 6 group) and knowing positive HBsAb before completion of scheduled vaccination(9.1% in 0, 1, 2 group and 7% in 0, 1, 6 group). CONCLUSIONS: There is no difference in Hepatitis B vaccination complet,ion rate bet.ween 0, 1, 2 group and 0, 1, 6 group.
