A 52-year-old man with multiple myeloma developed cutaneous nodules while being treated with melphalan and prednisolone. A biopsy specimen showed dermal infiltration by well differentiated plasma cells similar to those found on bone marrow biopsy. The use of peroxidase anti-peroxidase to demonstrate the monoclonality or polyclonality of the cytomplasmic immunoglohulins in the tumor cells revealed a positivity for IgG and 1 chain (ie, monotypic staining). Ultrastructurally, each plasmacytoma cell contained varyting amounts of rough endoplasmic reticulum and Golgi-apparatus. The cutnneous nodules completely disappeared after radiotherapy

Osteoporosis has recently been recognized as a major health problem in the elderly population. The disorder is manifested as a loss of bone mass accompanied by structural alteration of bone and increased incidence of fracture. Mandible also may be affected. So, I evaluated panoramic views of 66 postmenopausal women for finding the possibility of useful diagnostic mandibular parmeters of osteoporosis. To know the correlationship between skeleton and mandible, the average of the bone mineral density of lumbar from 2nd to 4th by the dual energy X-ray absorptiometry(DEXA, LUNAR DPZ. USA), and age and mandibular parameters, that is, the number of residual teeth, alveolar ridge resorption ratio, panoramic mandibular index (PMI), mandibular cortical width (MCW), angular cortical thickness (ACT), ramus cortical thickness (RCT), morphology of mandibular inferior cortical (MIC) were compared. And I divided the all tested women to the osteoporotic group and non-osteoporotic group by the use of T-score-2.0, which was derived from skeletal bone mineral density (BMD). To find the correlationship of the each group with mandibular parameters, t-test and discriminant analysis were done. The results of the t-test were that all parameters were highly related with 2 groups (p<0.05). Especially ACT, MIC, age have had even higher correlationship than others (p<0.001). The results of the discriminant analysis by the use of these ACT, MIC and age were that the discriminant function was Z =-2.973+(-1.447)x(ACT)+1.131x(MIC score)+(0.052)x(age), the cutting score was 0.257 and the classification accuracy was 84.8%. Therefore I suggest that the consideration of the angular cortical thickness (ACT), the age of patient and the morphology of mandibular inferior cortical(MIC) may help find the osteoporosis.

Bone graft is an important procedure in craniomaxillofacial reconstruction and the success of reconstruction depends on the survival of the grafted bone. In this study, the survival of the membranous inlay bone graft on the mandibles of dogs was investigated with bone scan and histologic examination. The inlay bone graft, 1x2cm critical-sized bone, was completely separated from the lower border of the mandible of dogs and then refixed to the original site. Bone scan and histologic examination were done at 1,2,3 and 4 weeks postoperatively. The bone scan after 1 week showed radioisotope uptake on the margin of the grafted bone and the isotope count was 21% compared to the uptake of the normal bone. After 2 weeks, the radioisotope uptake in the grafted bone increased to 52% of normal bone uptake. After 3 and 4 weeks, the degree of isotope uptake was 111% and 124% respectively. Histological findings after 1 week showed the absence of osteoblastic activity and 6 viable blood vessels in one 200X magnified field, which was 25% compared to the vessels of the normal bone. After 2 weeks, osteoblastic activities were noted and the number of viable blood vessels totalled 15, which was 63% of the vessels of the normal bone. After 3 weeks, osteoblastic activities increased and the number of viable blood vessels totalled 21, which was 88% of the vessels of the normal bone. After 4 weeks, there were markedly increased osteoblastic activities with a total number of 23 vessels, which was 96% of the normal bone. In summary, the revascularization of the membranous inlay bone graft began from the first week after bone graft, and then it gradually increased. After 3 weeks, the revascularization had returned to a nearly normal value compared with the value of the near-by normal mandibular bone.

Patau syndrome, or Trisomy 13 is one of the most common autosomal aberration associtated with multiple congenital abnormalities. We report a case with trisomy 13 mosacism which was found during an amniocentesis performed due to the age of the mother and abnormal nuchal translucency. The clinical features of fetus included cleft lip and palate, low set ears, polydactily, small ""micro"" penis, and Rocker-bottom feet. After termination of the pregnancy, the fetus was sent for an autopsy. The autopsy report was compatible with the gross findings and pulmonary hypoplasia, microophthalmia, hypoplasia of left ventricle of heart were found.

Plasma col1 leukemia with motility-related morphological behavior is rarely studied. The plasma cells have variable degrees of cytoplasmic morphologies as dairy Projections, long extensions and pseudopods. These morphological evidences show the papa bility of wide spread and dissemination of disease itself. We present a case of a 38 year old woman who had back pain for 4 months and was diagnosed as a solitary plasmacytoma of the third lumbar vertebra. In spite of resection of the tumor and chemotherapy, the plasmacytoma was disseminated into both breasts and ovaries within less than a year. On her blood examination, we counted 34% of plasma cells in peripheral blood and 91.6% of plasma cells in bone marrow aspiration. Most of them resealed hairy projections and pseudopods of the cytoplasm.

Study of dentofacial structure relationships relative to TMJ internal derangement is required to increase the predictability of TMJ internal derangement. But few studies have been reported. The purpose of this study is to reveal any correlation of dentofacial characteristics with TMJ internal derangement by lateral cephalometric analysis. Patients were devided into two groups. (1) Symptomatic patients with TMJ internal derangement (2) Asymptomatic volunteers with no TMJ internal derangement. Twenty symptomatic patients with TMJ internal derangement(7male, 13female) were selected from our clinic and had undergone a standarized clinical examination, panorama, transcranical view, TMJ tomography. Twenty asymptomatic volunteers(9male, 11female) were selected from our clinic with no pain, no limitation of motion. All subjects had undergone lateral cephalometric analysis. The results were obtained as follows. 1. No significant difference between ID and normal group is detected in cranial base. 2. Maxilla position of ID group is located more posterioly than normal group. 3. Mandible position of ID group is located more posteriorly than normal group and facial profile is hyperdivergent. 4. Posterior facial height of ID group is less than normal group thus facial profile is hyperdivergent. The patients, as mentioned, have a high prevalance of ID thus it should be careful in TMJ ID diagnosis and treatment.

The present study has been performed to evaluate 20 cardiopathy children and 20 healthy children's oral micorbes at the point of antimicrobial susceptibilities for antimicrobial prophylaxis to prevent bacterial endocarditis. The results were as follows: 1. Both groups had similar oral microbes. 2. The antimicrobial susceptibility of S. viridans were: Penicillin< Oxacillin< Ampicillin< Cephalothin< Erythromycin< Clindamycin< Gentamicin< Ciprofloxacin< Vancomycin=Imipenem. The cardiopathy group was slightly lower antimicrobial susceptibility rates than healthy group. 3. The antimicrobial susceptibility of Neisseriaceae were: Clindamycin< Erythromycin< Vancomycin< Penicillin< Gentamicin< Cephalothin< Ciprofloxacin< Imipenem. The antibiotics of bacterial endocarditis antibiotic prophylaxis regimens for dental procedures according to the American Heart Association were generally lower antimicrobial susceptibilities, so they were considered inadequate for the first selective antibiotics and Imipemem was best suitable antimicrobials. Conclusively, when choose antimicrobials for treatment or antimicrobial prophylaxsis for bacterial endocarditis, surveillant culture must be performed to evaluated personal antimicrobial susceptibilities of intraoral microbes for proper antimicrobial choice for dental procedures.
