Tardive dyskinesia(TD) is a serious side effect of long-term treatment with neuroleptic medications. To investigate if glutamatergic hyperfunction is associated with TD, effect of MK-801 on the prevention and treatment of TD was studied using a rat model, i.e., vacuous chewing movements(VCM). When comparing VCM scores of Group I(haldol decanoate+MK-801) with that of Group II(hadol decanoate+phosphate buffer saline), late measured VCM scores of former were significantly lower than that of latter, meaning that MK-801 is effective in the prevention of VCM. Furthermore, when MK-801 is also effective in the treatment of VCM. From the above results, it is suggested that glutamatergic hyperfunction might be involved in the development of TD and MK801 could be effective in the prevention and treatment of it.

A 19 month old girl with trisomy 18 is described. She showed loose folds of skin about the neck, a prominent occiput, a simian crease on both palms, epicanthal folds, acrocephaly, micrognathia, and unusual dermatologic features including total alopecia and no finger prints on either hands. Because of the simian crease on both palms, dermatoglyphics of both hands and total alopecia, a skin biopsy from the scalp and a chromosomal study were established at age 19-months, and an absence of hair follicles was observed, while peripheral blood lymphocytes demonstrated 47, XX, 4-18. To our knowledge, this would be the first recorded report on the dermatoglyphic pattern of Edwards syndrome in a Korean journal of dermatology.

PURPOSE: In order to study the frequency and the site of pain with shoulder impingement syndrome accompanied by myofascial pain syndrome (MPS), and to see how the treatment of impingement syndrome effects the improvement in myofascial pain. MATERIALS AND METHODS: Among patients diagnosed with shoulder impingement syndrome with MPS and who complained around of shoulder muscle pain 53 subjects were selected as subjects for this study. Patients were divided into three groups according to method of treatment; the first group was the cases who received impingement injection test, the second group were only carried out isometric strengthening exercise of the periscapular muscles and the rotator cuff, and the third group was the cases who failed conservative treatment and had a surgical operation. All subjects had a physical examination before treatment to see if the MPS was present in the muscles around the shoulder, the range of motion of shoulder, and the American Shoulder and Elbow Society (ASES) shoulder score were measured. RESULTS: There was no relation to between age, gender, impingement signs, tenderness around the joints, the range of motion and ASES shoulder score. The VAS was reduced from 6.2+/-2.3 to 1.2+/-1.5 (p<0.01), and ASES shoulder score increased from 32.1+/-15.3 to 87.5+/-17.7 (p<0.05). The differences among treatments of the three groups were not significant in pain and treatment outcome (p>0.05). CONCLUSION: Treatment of shoulder impingement syndrome reduced the symptoms of MPS, thus shoulder impingement syndrome can be the one of the causes of MPS.

Hydatidiform moles are generally separated into two clasifications. Complete hydatidiform moles are characterized by cystic swlling of all villi, often pronounced trophoblastic hyperplasia, lack of fetal parts, all 46 chromosomes of paternal origin(androgenesis), and a major risk for persistent trophoblastic tumor. Partial hydatidiform moles appear to be a milder version of complete moles with both normal and cystic villi, focal trophoblastic hyperplasia, a fetus or indications of previous fetal existence, 69 chromosomes with a maternal contribution, and a malignant potential less than described for complete moles. Hydatidiform mole with coexistent fetus is a very rare phenomenon, with an estimated incidence of 0.005 to 0.01 percent of all pregnancies. The rarity of live-born, surviving children may in part be due to termination of pregnancies, when molar parts are observed and without access to current advanced diagnostic procedures. Progress in techniques for first trimester prenatal diagnosis and improved surveillance of first trimester pregnancies through prenatal chromosomal analysis, ultrasound scan, maternal serum-hCG and serum- AFP screening has created complex situation, allowing confirmation of hydatidiform mole with coexisitng fetus. We recently experienced one case of unusual pregnancy with complete hydatidiform mole and coexisiting live fetus.

The stress distribution generated in the surrounding bone was calculated and compared for various geometry of the dental implants by means of the finite element methods. The models were designed to represent the screw type endosseous implants (varing the size, shape, direction of the screw thread and the angle of the body) with supporting bone and the cylinder type endosseous implants (varing the lower portion-Round type, tapered type) with supporting bone. Static mean bite forces were applied 100N vertically and 25N horizontally on the center of the implant and three dimensional finite analysis was undertaken using software ANSYS 5.1 Version. The result demonstrated that different implant shape leads to significant variations in stress distribution in the bone. In the case of variation of the screw size, direction and shape the implant model with normally directional and triangular screw implied lower stress than with upper directional or lower directional and quadrangular screw but among models a different screw size, within a variation of 0.2mm there was no meaningful difference in maximum stress. In the case of variation of angle of body the straight implied lower stress than the tapered. As a result of analysis of cylinder type, the implants with larger radius of curvature of the round form and larger diameter of the tapered form implied lower stress.

BACKGROUND: Histological differentiation between malignant melanoria and benign melanocytic skin lesions is at times, a difficult task for the dermatopathologist. The AgNOR staining has been regarded as a useful tool in differentiating malignant melanoma from benign rael;inocytic nevi. OBJECTIVE: We have carried out the AgNOR staining in a range of nelanocytic lesion and try to assess the value of AgNOR stairting in the identification of malignancy in melanocytic lesions. METHOD: Fifty seven melainocytic skin specimens were studied. These comprised 11 acquired melanocytic nevi, 11 congenital melanocytic nevi, 31 malignant melano nas and 4 atypical melanocytic hyperplasias. RESULT: The majority of benign nevus cells posessed one or two unifrm AgNORs, whereas marked AgNOR pleomorphism was found in some rnelanoma cells. The number of AgNORs per nucleus. averaged 1.24+0.12 in the 18 specimens of benign nevi and 2.10+0.6 in the 25 specimens of malignant melanoma. In the cases of atypical melanocytic hyperplasia it was not possible to count on an adequate number of cells to give a meaningful result because of melanin pigment. CONCLUSION: Although this study demonstrated a separation of average AgNOR counts between begnign melanocytic nevi and maligmant melanomas, there was an ovei lap in counts among individual lesions. For clinical use, there should be a standard method by which AgNORs are counted in AgNOR staining. Melanin pigment masiking the AgNORs can also be a problem.
