Trichotillomania is the cllinical syndrome of alopecia resulting from the repetative pulling, plueking and breaking of ones own hair. We report four cases of trichotillomania in 10 year old children. The lesions were limited to the scalp. All of them had psychiatric problems in the school or home according to a psychiatric consultation. The histopathologic examinatiorii revealed a normal number of hair follices, empty hair follicles and no inflammatory reaction. The treatment led to hair growth in three cases but one case did not respond to the treatment.

Backgroud : The number of proliferating cell populations in the hair is follicles is closely related to the regulation of hair growth. Destruction of hair germ cells and the loss of proliferating cells have been suggested to be of major pathogenetic significance in alopecia areata OBJECTIVE: The purpose of this study is to compare the growth frrections in proliferating cells of normal hair follicles with those in alopecia. METHODS: An immunohiatochemical study was done to detect the proliferating cells in hair follicles using a monoclonal antibody against proliferating cell nuclear antigen(PCNA) in the scalp biopsy of an alopecia patient on the peraffin embedded sections. RESULTS: A significant decrease of the labelling indeces of PCNA were observed in the hair follicles of alopecia compared with normal condition. But we could not find significant differences of labelling index in the clinical types of alopecia, responses to treatment, anc systemic immunologic state. CONCLUSIONS : Whole the above results confirmed that significant decreases of proliferating cells in the hair follicle could explain the part of the pathogenetic mechanism in alopecia, its direct cause which inhibit the proliferation of cells is not clear.

A 7-year-old girl had a 7 × 6cm sized dark red colored tumor on the left elbow and several erythematous macules on the face, right upper arm, and both thighs. Her general health was good and all laboratory findings were within normal limit. Histopathologic examination revealed an infiltration of atypical mononuclear cells in the dermis and subcutis. L26 and leukocyte common antigen were positively stained in an immunohistochemical study. According to clinical, histological and immunohistochemical findings, we diagnosed the disease as primary cutaneous B cell lymphoma. The patient's skin lesions markedly improved after a surgical excision and chemotherapy.

It has been emphasized that the treatment of choice for the trochantric fracture of the femur is open reduction and rigid internal fixation to reduce complications by early ambulation. The incidence of trochanteric fracture of the femur in the young age group has been considerably increased in recent years because of increased traffic and industrial accidents. The author treated 38 cases of trochanteric fracture of the femur in the year 1974 through 1979, at the Department of Orthopaedic Surgery, School of Medicine, Soon Chun Hyang College. The results were as follows: 1. In sex distribution, 24 out of 38 were males and 14 were females. 16 cases out of 24 male patients were in the age group 20-40 and 9 cases out of 14 female were over 60 years of age. Over all mortality was 7.9%. 2. The numbers of patients of type I and III were 11 cases in each type out of 38 trochanteric fracture. 3. 26 cases out of 38 cases were treated by open reduction and internal fixation and the others were by traction and cast. 4. The applied metal devices were 3 types: Smith-Peterson nail and Thornton or McLaughlin plate, compression hip screw, and multiple pinning. 5. Mean duration of bony union is shorter in the group of open reduction and internal fixation (13 weeks) than the group of traction and cast (15 weeks). The cause of difference is that the 6 out of 9 cases of type IV and V were included in conservative group. 6. The incidece of the complications such as coxa vara, slipping screw, long nail and traction palsy occurred higher in the group fixed with Smith-Peterson nail and plate than the group fixed with compression hip screw.

We report a spontaneous embryonal rhabdomyosarcoma in the abdominal cavity of an aged (88-week-old) Sprague-Dawley rat. The animal had a firm lobulated 5 x 5 x 4.5 cm mass in the abdominal cavity that was whitish to tan with necrotic and hemorrhagic plaques. Microscopically, the mass contained nodules with spindle or globoid shaped neoplastic cells with abundant eosinophilic cytoplasm and round or elongated nuclei mixed with other spindle cells with a filamentous appearance and scanty cytoplasm. Multinucleated cells and cross-striations were also observed. The neoplastic cells were positive for vimentin, desmin, and alpha-smooth muscle actin, especially the small spindle cells.

A fixed drug eruption is a cutaneous reaction caused by various drugs, which include phenazone derivatives, barbiturates, sulfonamides, tetracyclines and phenolphthaleins. An eruption caused by piroxicam is very rare and there have been no previous reports in Korea. A 49-year-old woman was seen with mutiple erythematous patches and some bullae that appeared after oral administration of piroxicam. The patient had had two similar episodes after oral administration of piroxicam. We performed patch test with piroxicam and could confirm a fixed drug eruption caused by this durg.

Ten cases infected with Taenia saginata were treated with Bithionol, 2, 2' thiobis (4,6-dichlorophenol) which is well known as an excellent anthelminthhic against paragonimiasis and their follow-up studies were carried on within 3 to 12 months after treatment. Bithionol, 50 mg dose per kg of body weight was divided into two equal dose and administered orally in 30 minutes intervals. Three hours later, this was followed with a sodium sulfate or magnesium sulfate purge. The strobilas without scolices were found in the stools after the medication and the follow-up studies have shown the complete deworming in all cases. It is well tolerated, toxic effects being uncommon and when present, limited to mild gastro-intestinal disturbances.

Liver has a dual blood supply from portal vein and hepatic artery. Hepatocellular carcinoma receive their blood supply almost exclusively from hepatic artery. Thus, the concept of treating hepatocellular carcinoma by chemoembolization through these arteries is very effective. However, there may be several collateral or parasitic vessels feeding them in case of huge tumor or previous chemoembolization. We experierced a case of huge tumor involving right upper posterior portion of liver fed by 9th, 10th, 11th right posterior intercostal arteries and an anomalous hepatic artery. We tried chemoembolization with Adriamycin-Lipiodol suspension and Gelfoam material through the right posterior intercostal arteries to treat the lesion. After the procedure, the patient(55 years old female) became paraplegic with voiding and defecation difficulty which could be due to spinal cord infarction .by anterior spinal arteri. al occlusion caused by embolic material through the artery of Adamkiewicz from a posterior intercostal artery. She recovered completely after 20 days of treatment.
