Three cases of orbital rhabomyosarcoma are reported here. Histological studies comfirmed the lesion 1:0 be the alveolar type in all cases. This tumor is a rare disease entity in Orient than Europe and America and accordingly, rarely encountered in our ophthalmologic practice, although it is the commonest primary malignant orbital tumor in children. Of the three cases reported here one occurred in adu1t and the other two in children. Case I. This 15 month old male showed a swelling of the left upper lid toward the medial side for 2 months and visited to our hospital on March 10, '69 with complaints of progressive swelling on the region with ptosis. The eye ball was slightly displaced toward the lower temporal side and ocular movement is limitted to upward. On palpation, the childthumb sized tumor was palpable in the upper nasal portion of the orbit. On excision of the tumor, the mass was found to be originated from the superior oblique muscle. The mass round measuring 2.5 X 2.5 X 1.5 cm in size. Histological diagnosis was alveolar rhabdomyosarcoma without cross-striation. No follow-up could be done. Case II. This patient of 15 month old male showed a swelling on the right lower lid existed 6 months and visited to our hospital on September 8, '69. The physical examination revealed that the left eye and the other routine examinations were within normal limits. The right eye showed the swelling of the lower lid, congestion of the palpebral conjunctiva, limitted movement of the eye ball toward the lower side and a palpable bean-sized mass on the region. The excision of tumor was performed under the general anesthesia. This mass was attached with the inferior oblique muscle with no other recognizable adhesion seemingly originating from that muscle. The mass was round and oval in shape, measuring 2 X 2 X 1 cm in size, diagnosis was alveolar rhabdomyosarcoma. The post-operative follow-up studies were unavailable. Case III. This case in one of adult alveolar rhabdomyosarcoma. At the age of 25 years, this man showed a proptosis of the right eye associated with migrain like headache, ocular pain and visual disturbance. This symptoms existed 6 months and gradually increased in intensity. On the physical examination, the left eye was found to be normal. The skull and orbit x-ray and c.b.c. were with in normal limits. The right eye revealed about 5mm proptosis compared with left eye and the adult thumb sized tumor was palpated on the inner side of the lower orbital rim. The visual acuity was in zero. The right optic disc was edematous and elevated about 4.0 D. The pupil showed marked dilatation and the light reflex was abscent and ocular movement was markedly limitted and eye ball is deviated toward the upper side. Under the general anesthesia, the exenteration of the orbit associated with the removal of tumor was carried out with no untoward complications. Origin of the mass was the inferior oblique muscle penetrating to the deeper part of the optic foraman and optic nerve was surrounded by the tumor completely Histology confirmed alveolar rhabdomyosarcoma. Follow-up study was impossible.

The increased incidence of the trochanteric fracture of the femur was accompanied by the development of the vehicle and the prolongation of the average life-span. Recently it has been also increased in an active person from thirties to forties. 87 cases of the trochanteric fracture of the femur in 86 patients who have been admitted and treated at the Department of Orthopedic Surgery of Hanyang University Hospital during 8 years and 10 months, from May, 1972 to February, 1981, were reviewed. The results of this study were as follows: 1. The trochanteric fracture of the femur was more common in male and was frequent in a person who was from thirties to forties and who had vigorous social activity. 2. An injury from traffic accident was the most common cause of the fracture from thirties to forties and an injury from slip down was most common in seventies. 3. The unstable fracture which was classified by Evans' classification, Boyd and Griffin Type II Fx. and Tronzo Type III Fx. were most common in the intertrochanteric fracture and the Fielding Type II Fx. was most common in the subtrochanteric fracture of the femur. 4. Other injuries were accompanied by the trochanteric fracture of the femur in 38 patients (44.2%) and the pelvic bone fracture was the most common associated injury in these patients. 5. The weight bearing was allowed earlier in the patient who had been given the surgical Tx. than in the patient who had been given the conservative Tx. 6. In adults, there was no significant differences in the duration to achieve the bony union between the conservative treatment and surgical treatment performed. 7. We considered that the diminution of the probable complications by early weight bearing after accurate open reduction in accordance with the Type of the Fx. followed by secure internal fixation with devices is an ideal method of the Tx.

Pilomattiaoma, aften called calcifying epithelioma of Malherbe, is a benign tumor originating from the outer root sheath cell of the hair follicle and extending into the hair matrix, Pilomatricoma usually occurs as a single, asymptomatic dermal or subcutaneous nodule. Multiple lesions are quite unueuel, comprising only 2-3.5% of cases. We report two patients with multiple pilomatricoma.

The developement of squamous cell carcinoma from the draining sinus of chronic osteomyelitis has long been recognized as a rare and late complication. The mode of developement of carcinoma at the site of chronic osteomyelitis is not well understood. This, however, is chiefly a disease of middle aged men, and tibia is the most common site. There are two types in this carcinoma; superficial and deep types. In the superficial type obvious presence of fungaiing growth makes diagnosis simple and easily confirmed by biopsy. In the deep type the diagnosis is difficult clinically, but the features most frequently described are an increase in pain and discharge with swelling and hemorrhage. Amputation at the adequate level is the treatment of choice. Three cases of the disease involving one left femur, and two left tibiae are reported with review of literature.

A finite element analysis has been utilized to analyze stress and strain fields and design a new configuration in orthopedics and implant dentistry. Load transfer and stress analysis at implant bone interface are important factors from treatment planning to long term success. Bone configuration and quality are different according to anatomy of expecting implantation site. The purpose of this study was to compare the stress distribution in maxilla and mandible according to implant length and bone engagement types. A three dimensional axi-symmetric implant model(Nobel Biocare, Gothenburg, Sweden) with surrounding cortical and cancellous bone were designed to analyzed the effects of bone engagement and implant length on stress distribution ANSYS 5.5 finite element program was utilized as an interpreting tool. Three cases of unicortical anchorage model with 7, 10, 13mm length and four cases of bicortical anchorage model with 5, 7, 10 and 13mm lenght were compared both maxillary and mandibular single implant situatiion. Within the limits of study, following conclusions were drawn. 1. There is difference in stress distribution according to cortical and cancellous bone thickness and shape. 2. Maximum stress was shown at the top of cortical bone area regardless of bone engagement types. 3. Bicortical engagement showed less stress accumulation when compared to unicortical case overall. 4. Longer the implant fixture length, less the stress on cortical bone area, however there is no difference in mandibular bicortical engagement case.

It has been widely accepted that complete surgical resection of hepatoblastoma is essential for long-term survival. But unfortunately less that 50% of hepatic tumors in children can be totally removed at the time of diagnosis. This report is to present the experience of successful resection of hepatoblastoma after concurrent radiotherapy with transarterial chemoinfusion in a child. We believe this modality of treatment enables complete resection of unresectable hepatoblastoma, which is resistant to the systemic chemotherapy.

PURPOSE: The goal of intermittent androgen deprivation (IAD) therapy in prostate cancer patients is to delay the disease progression and improve the survival rate. Therefore, the duration of off-treatment is very important for the effective treatment outcome of IAD. We analyzed factors that influence the duration of off-treatment in IAD. MATERIALS AND METHODS: We reviewed the medical records of 45 patients with prostate cancer who had completed at least 1 cycle of IAD. Uni- and multi-variate tests were used to determine the factors, which are predictive to the duration of off-treatment. These factors included: the patient's age, biopsy Gleasons score, initial PSA, presence of bone metastasis, PSA levels at 3 months following on-treatment and at 3 months following off-treatment, and the duration of on-treatment. RESULTS: The average follow up duration was 34 months (15-71 months). The average off-treatment duration of each cycle was 11.1 (4-40), 7.5 (4-14), and 5.6 (3-10) months for the 1st, 2nd and 3rd cycles, respectively. Independent factors associated with the extension of duration of off-treatment, by univariate tests, included: initial PSA value, PSA values at 3 months following on-treatment, PSA at 3 months following off- treatment, and duration of on-treatment. The duration of off-treatment was inversely related to the serum PSA level at the start, 3 months following on-treatment, and 3 months following off-treatment, while it was directly related to the duration of on- treatment by multivariate tests. CONCLUSIONS: The pretreatment serum PSA level and the serum PSA level at 3 months following on-treatment and off-treatment were valuable predictors for the duration of off-treatment in IAD.

Melanosis coli is the brownish pigmentation of the colon associted with the ingestion of anthraquinone compounds as iaxatives. The brownish discoloration of the colon mucosa is due to accumulation of macrophage containing lipofuscin pigment in the lamina propria. This is the one of the complications of laxative abuse, but the pigments disappear by withdrawing the anthraquinone. We report a case of malanosis coli histologically confirmed by fibersigmoidoscopic biopsy in a 70-year-old female patient consuming anthraquinone compound for twelve months with a review of the literature.

Although acquired ichthyosis has been associated with a number of systemic illnesses, an association with sarcoidosis has rarely been reported. We report a patient with aquired ichthyosis of the lower and upper extrimities whose diagnosis of cutaneous sarcoidosis was confirmed by histologic examination. Systemic involvement in the patient revealed occular, pulmonary and nerve disease. A diagnosis of sarcoidosis must be considered when a patient presents with acquired ichthyosis.

PURPOSE: This study compared the accuracy of an abutment-framework (A-F) taken with open tray impression technique combining cementon crown abutments, a metal framework and resin cement to closed tray and resin-splinted open tray impression techniques for the 3-implant definitive casts. The effect of angulation on the accuracy of these 3 techniques was also evaluated. MATERIAL AND METHODS: Three definitive casts, each with 3 linearly positioned implant analogs at relative angulations 0, 30, and 40 degrees, were fabricated with passively fitted corresponding reference frameworks. Ten impressions were made and poured, using each of the 3 techniques on each of the 3 definitive casts. To record the vertical gap between reference frameworks and analogs in duplicate casts, a light microscope with image processing was used. Data were analyzed by two-way analysis of variance and the Tukey test. RESULTS: The open tray techniques showed significantly smaller vertical gaps compare to closed tray technique (P < .05). The closed tray and the resin-splinted open tray technique showed significantly different vertical gaps according to the angulation of implant (P < .05), but the A-F impression technique did not (P > .05). CONCLUSION: The accuracy of the A-F impression technique was superior to that of conventional techniques, and was not affected by the angulation of the implants.
