Bowens disease is generally regarded as a premalignant dermatosis. If untreated, 3% to 5% of patients may develop squamous cell carcinoma. However, sebaciou carcinoma arising from Bowens disease is very rare. We presented a case of quarnous cell carcinoma and sebaceous circ s disease in a 68 year-old male. He had multiple bowenoid skin lesi nsties. A bean-sized nodule as developed on the bowenoid lesion of the he had a large yellow crust.ed exudative tumor on the Rt. thigh. We took a biopsy specimen of these three discrete lesions. The nu lipid stain of frozen section revealed Bowens disease, squarnous concllnoma arising from Bowen on the trunk and extremi Rt. lower abdomen. Almost of routine histology and carcinoma, and sebaceous carcinoma, respectively.

PURPOSE: Long-term administration of anticonvulsants for pediatric epileptic patients may cause changes of bone metabolism. This study was performed to evaluate the influence of antiepileptics on the bone metabolism and growth in pediatric patients who received antiepileptics. Methods for early detection of adverse bone metabolism were also evaluated. METHODS: Forty-eight epileptic patients were enrolled in this study. All subjects had taken antiepileptics for at least 6 months. Subjects were grouped according to the antiepileptics : Group I(n= 31) was treated with carbamazepine(CBZ), Group II(n=9) used valproic acids(VPA), Group III(n=8) received multi-drugs including CBZ, VPA. We determined serum osteocalcin and total alkaline phosphatase levels as markers of bone formation, and urinary deoxypyridinoline as marker of bone resorption. Blood and urine samples were collected before the initial medication and follow up at least 6 months later. Serum osteocalcin and urinary deoxypyridinoline were measured by an ELISA method, respectively. Data from subjects were analyzed statistically by SPSS(ver. 10). RESULTS: Concentrations of serum osteocalcin and urinary deoxypyridinoline were significantly increased in the carbamazepine treated group. The increment of deoxypyridinoline positively correlated with the duration of treatment, especially in children who received carbamazepine therapy for more than 12 months(P<0.05). The serum concentration of calcium, phosphorus were within normal ranges, but the levels of alkaline phosphatase were significantly increased in all group(P<0.05). CONCLUSION: Our data suggests that serum osteocalcin and alkaline phosphatase, urinary deoxypyridinoline could be useful markers for the early detection of harmful bone metabolism during antiepileptic treatment.

OBJECTIVE: The purpose of this study was to evaluate the efficacy and effect of various cryopreservation method on the survival and the cytoskeletal stability of metaphase II mouse oocyte. METHODS: Mouse ovulated oocytes were collected and cryopreserved by a modified slow-freezing method with 1.5 M 1,2-propanediol (PrOH)+0.1 M sucrose or by vitrification using cryo loop and EM grid with 40% ethylene glycol+0.6 M sucrose. Four hours after thawing, intact oocytes were fixed and stained with fluorescein isothiocyanate (FITC)-conjugated monoclonal anti-beta-tubulin antibody to visualize spindle and propidium iodide (PI) to visualize chromosome. Spindle morphology was classified as follows: normal (barrel-shaped), slightly and absolute abnormal (multipolar or absent). RESULTS: Survival rate of the frozen-thawed oocytes in vitrification group was significantly higher than that of slow-freezing group (62.7% vs. 24.4%, p<0.01). Vitrification with cryo loop showed significantly higher survival rate than that with EM grid (67.7% vs. 53.5%, p<0.05). On the other hand, proportion of normal spindle and chromosome configurations of the frozen-thawed oocytes between two vitrification group was not significantly different. CONCLUSION: For mouse ovulated oocytes, vitrification with cryo loop may be a preferable procedure compared to slow-freezing method. Further study should be needed to investigate developmental competency of frozen-thawed mouse oocytes.

Miller-Dieter syndrome consists of severe type I lissencephaly, abnormal facial appearance, and sometimes other birth defects. Lissencephaly is a brain malformation manifested by a smooth cerebral surface, thickened cortical mantle, and microscopic evidence of incomplete neuronal migration. It comprises the agyria-pachygyria spectrum of malformation, thus excluding polymicrogyria and other cortical dysplasia. Type I lissencephaly results from abnormal migration between about 10 and 14 weeks gestaion. The brain is often small, and the ventricle is enlarged posteriorly The corpus callosum may be small or absent. The structural pattern of the cerebral hemispheres and ventricles is distintly immature, reminiscent of fetal brain. The superficial cellular layer resembles an immature cortex, with some separation into zones similar to layers III, V, and VI of normal cortex, although the cell population is decreased. In 1963 Miller described a malformation syndrome in a brother and sister with postnatal growth deficiency, craniofacial defects, and serious abnormalities of neurologic function. Autopsy at 3 and 4month of age, respectively, revealed lissencephaly. Subsequently, Dieker reported four additional patients with this disorder and referred to it as the 'lissencephaly syndrome'. We have experienced a case with this syndrome. Then we report this rare case with brief review of literature.

7.Cervical Myelopathy Induced by Posterior Vertebral Body Osteolysis after Cervical Disc Arthroplasty
Journal of Korean Neurosurgical Society 2023;66(5):591-597
Cervical disc arthroplasty (CDA) has become more widespread and diverges from the conventional technique used in anterior cervical fusion for cervical degenerative disc disease. As arthroplasty has become a popular treatment option, few complications have been reported in the literature. These include subsidence, expulsion, posterior avulsion fractures, heterotopic ossification, and osteolysis. One of the critical complications is osteolysis, but current studies on this subject are limited in terms of not elucidating the incidence, etiology, and consequences. The authors present two cases, who presented with clinical signs of gradually worsening myelopathy induced by posterior vertebral body osteolysis, 2 years after CDA. Subsequently, the patient underwent posterior decompression and fusion without prosthesis removal. Postoperatively, the clinical symptoms gradually resolved, with no severe deficits. The present rare cases highlight the osteolysis that occurs after CDA, which can cause cervical myelopathy, and suggest spine surgeons to be alert to this fatal complication.

Primary germ cell tumor of the testis is rare, which occupies 1 to 2% of all reported malignant male neoplasms. Combined primary germ cell tumor of the testis composed of embryonal carcinoma and seminoma is more rare tumor. The authors experienced a case of 50-year old male who presented with painless enlargement of right testicle. He has had radical orchiectomy and diagnosed by pathologically as combined germ cell tumor of testis. The testicle is measuring 180 gm in weight and 9×6×5 cm in dimension, and almostly replaced by tumor mass. Grossly the tumor is rubbery solid smooth tumor mass, with variegated cut surface with geographically outlined diffuse necrotic area. Histologically the tumor is composed of two components of tumor, which are solid growth pattern of large round to polyhedral cells with clear or granular cytoplasm and distinct cell border, and anastomosing glandular and papillary arrangement of anaplastic epithelial cells. The former corresponds to seminoma, and the latter to embryonal carcinoma. Each tumor lobule is separated by abundant fibrous stroma.

PURPOSE: The purpose of this review article is to introduce how the Korean Society of Genetic Nursing (KSGN) has evolved and tried to translate genomic knowledge to nursing practice, and then to suggest the future role of genetic nurses in Korea. METHODS: A literature review was performed and the current status of genetic counselling in Korea was explored. Then the educational and clinical experiences of the authors were incorporated. Finally, the main activities of Korean nursing for genetics were identified. RESULTS: Two types of genetic counsellor certification have been issued in Korea: one is issued by the Korean Society of Genetic Medicine, another by the Korean Society of Breast Cancer since June 2011. A few Korean nursing researchers have continuously performed research related to genetic nursing and undertook several research projects funded by the government since 2003. In February 2011, KSGN was established and is now trying to establish further international networks. CONCLUSION: Nursing genetic experts should be trained to integrate all specialties for genetic counselling, so they can provide holistic genetic services including ethical, legal, and social issues (ELSI).
