The simultaneous existence of intrauterine and extrauterine pregnancies is known as a heterotopic pregnancy. Spontaneous heterotopic pregnancy is a rare event although its incidence has increased since the recent development of treatment of infertile women with ovulation induction or in-vitro fertilization and embryo transfer(IVF-ET).The theoretical rate of this condition was estimated to be approximately 1 in 30,000 pregnancies. The early diagnosis of heterotopic pregnancy is very difficult . So there is a high maternal morbidity and fetal loss. We reported a IVP - ET patient resulting in the successful delivery of live infant at 35weeks of gestational age from intrauterine pregnancy following surgical removal of ruptured concurrent extrauterine pregnancy.

We report a case of doxycycline-induced phototoxicity in a 62-years-old male. The patient, had erythematous macules and patches on sun-exposed areas. A Phototest revealed a marked decreased minimal erythemai. dose (MED) to UVA (MED(UNA)=-10J/cm2). Photopatch tests with 1%, 5% Doxycycline ointment were negative. An oral provocation test was performed, which showed a positive result with a decrease of MED to UVA (MED(UVA)= 20J/cm2). After the cessation of doxycycline, his skin lesioris were improved markedly with complete loss of photosensitivity.

Herpes Simplex Encephalitis is associated with a high mortality rate and a high probability of neurological sequelae. Good results are obtained when Herpes Simplex Encephalitis is promptly diagnosed and treated with antiviral agents. We reported a case of Herpes Simplex Encephalitis in which Magnetic Resonance Imaging (MRI), Single Photon Emission Computed Tomography (SPECT) and Fluorodeoxyglucose-Positron Emission Tomography (FDG-PET) were performed sequentially. Imaging studies are valuable tools for early detection and diagnosis of Herpes Simplex Encephalitis. And particularly FDG-PET represents functional anatomy through diffuse decline of glucose metabolism better than other imaging studies.

We have done clinical analysis of 92 cases with chronic subdural hematoma, admitted to our department from August 1, 1984 to July 31, 1987. The following results were obtained; 1) The ratio of male versus female was 3.6:1, and 6 cases(71.7%) were over 50 year-old age. 2) 50 cases(75.7%) in older group(over 50) had head trauma history, and 11 cases(42.3%) in younger group(under 50). 3) The major clinical symptoms and signs in older group were mental deterioration and hemiparesis, in younger group headache and vomiting. 4) The hematoma densities in CT on admission were hyperdense 1.0%, isodense 33.7%, hypodense 39.3%, and mixed 25.9%. The shapes were biconvex 45.7%, planoconvex 35.8%, and crescenteric 18.5%. 5) The operation method was either burr hole drainage, or craniotomy with membranectomy, according to patient's physical condition and CT findings. In postoperative results there was no significant difference in both.

Bednar tumor was described by Bednar in 1957. The histologic pattern of this tumor shows similar to dermatofibrosarcoma protuberans (DFSP) but melanin pigments are scattered within the tumor, It's rare neoplasm accounting for approximately 1-5% of all case of DFSP. Clinically, this tumor is considered to be intermediated malignancy, because of slow growth and frequent local recurrence and lack of distant metastasis. The majority are located on the trunk and the upper and lower extremities, but extremely rate in the head and neck area. Microscopically, this tumor is characterized by tight storiform spindle cells and long slender cells that admixed with a small population of melanin containing dendritic cells. This dendritic cells are the primary features distinguising this lesion from conventional DFSP. Complete surgical excision and close follow-up case are necessany for this neoplasm because of probable intermediate malignancy. A patient was admitted to Our Department of Oral and Maxillofacial Surgery due to swelling on right parotid area and numbness of the right lower lip on September, 1994, By clinical examinations and C-T finding, we dignosed tentatively as myxoma or pleomorphic adenoma. Surgical excision of this tumor was performed with parotidectomy and mandibular osteotomy under the frozen biopsy. By final microscopic and electromicroscopic examination and immunohistochemical study, this tumor was diagnosed as Bednar tumor. So, we report a case of pigmented DFSP with review of literatures.

The purpose of this study was to evaluate the difference of subgingival bacterial compositions between periodontally healthy and diseased sites. Subgingival plaque samples were obtained from 100 sites in 20 untreated adult periodontitis patients(experimental group), and 100 sites in healthy individuals(control group). Before sampling, probing pocket depth(PPD) and clinical level of attachment(CAL), Plaque Index(PI), and Sulcus Bleeding Index(SBI) were recorded for each sampled sites. Microbial samples were collected from the bases of gingival sulci or periodontal pockets with sterile curettes. The samples were examined under darkfield microscope(x400). At least 150 bacteria were evaluated and categorized on the basis of bacterial morphology and motility, i.e. cocci, non-motile rods, motile rods, and spirochetes. In control group, subgingival microbial flora consisted of 73.7% of cocci, 20.0% of non-motile rods, 4.3% of motile rods, and 2.0% of spirochetes. The microbial samples from experimental group consisted of 51.5% of cocci, 19.4% of non-motile rods, 17.6% of motile rods, and 11.6% of spirochetes. The proportion of cocci was higher in control group than in experimental group. Proportions of motile rods and spirochetes were higher in experimental group than in control group. The proportion of nonmotile rods in experimental group and control group was not significantly different. Sulcus Bleeding Index and Plaque Index showed high correlation with the bacterial composition. These findings suggests that examination of subgingival bacterial proportion may serve as more sensitive mirror of the local periodontal status than clinical parameters.
