Recently, the possibility of inappropriate management of undiagnosed early cancers increased with spreading laparoscopic approach of adnexal tumors. The pathologic diagnosis of frozen section biopsy(FBx) guide the surgeon to perform the appropriate surgical procedure of adnexal tumors. This study was conducted to verify preliminarily the criteria for the laparoscopic management and determine the accuracy and efficacy of conditioned FBx according to the criteria. The inclusive criteria of FBx results in this study was designed by means of the preoperative transvaginal sonography(morphologic score >or=10) or tumor marker level of serum(CA-125 level>or=35 U/ml in postmenopause and >or=65 U/ml in postmenopause) or suspected gross findings of the malignancy during operation. On the other hand, cases which were convinced as dermoid cysts, endometriomas and advanced(>or=IIIb) ovarian cancers on the basis of gross findings were excluded in this study. Two hundred seventy-six operations of adnexal tumors were performed between January 1995 and June 1996 and 74 results of FBx were picked up in this study. The overall rate of conditioned FBx was 26.8%(74/276). The applied criterion in this study had the sensitivity of 0.97, specificity of 0.78, negative predictive value of 0.99, positive predictive value of 0.36. The accuracy of frozen sectional biopsy were 87.8% in the histopathologic diagnosis and 97.3% in the clinicopathologic diagnosis. The sensitivity, specificity, negative predictive value and positive predictive value for ovarian cancers(borderline+malignant) were 1 in all. It was thought that frozen sectional biopsy was a appropriate guide for the decision of methods during operation of adnexal tumors and that the criteria in this study could be used as a guideline for frozen section biopsy in the laparoscopic surgery of adnexal tumors.

Letterer-Siwe disease, Hand-Schuller-Christian disease and eosinophilic granuloma of the bone are merely different clinical expressions of one disease. Lichtenstein grouped these three clinical syndromes and proposed that this disease be termed histiocytosis X. This grouping was based on the histologic similarities and the possibility of transformation of one syndrome into another. The cause of histiocytosis X remains unknown. Histiocytosis X is a condition that presents single or multiple lesions, distributed in the soft tissue, lymph nodes, various organ and bones, especially in the areas of marked reticuloendothelial activity. The authors reviewed the clinical findings, radiographs and the treatment of the twenty-six patients with histiocytosis X diagnosed on the base of pathologic findings at Severance Hospital, between January, 1971 and December, 1980. Among the twenty-six patients, twenty-one patients could be followed, ranging from one month to six years, with an average follow-up of 1.6 years. The results obtained were as follows: 1. There was a slight male predominance (61.6%). The age ranged from 2 months to 42 years (average 8.2 years). Sixty-five percents of patients were the child under 4 years of age. 2. Hand-Schuller-Christian disease (50%) was the most common form of this disease. Letterer-Siwe disease developed in the youngest (average 1.2 years) and eosinophilic granuloma in the eldest (average 20.4 years). 3. The common manifestations were hepatomegaly, skin rashes and anemia in Letterer-Siwe disease; palpable mass, pain and exophthalmos in Hand-Schuller-Christian disease; pain and mass in eosinophilic granuloma. 4. The common sites of the skeletal lesions were skull, spine and femur, etc. 5. The patients with single skeletal lesion improved regardless of the methods of treatment. 6. Vinblastine, methotrexate and/or prednisone were valuable agents for the multiply involved patients. 7. Prognosis was poor for the patients who were young at onest, or who had multiple systemic involvements, but in case only with skeletal involvement the prognosis was good. Eosinophilic granuloma is the most benign variant, while Letterer-Siwe disease is the most malignant type.

BACKGROUND: Seroincidence of hepatitis B virus (HBV) among Korean blood donors has not been reported. This study was conducted to calculate the seroincidence of HBV among blood donors and to estimate the risk of post-transfusion hepatitis B by donated blood in window period of infection. METHODS: HBV seroincidence was calculated among repeat-donors who had donated from Nov. 1994 through Dec. 1996. To calculate the person-years, the database of the Korean National Red Cross was used in which results for HBsAg enzyme immunoassay were filed up. The observed incidence was adjusted by interdonation interval of incident cases, who were defined as donors showing seroconversion. The risk of post-transfusion hepatitis B by donated bloods in window period of infection was estimated. RESULTS: HBV seroincidence was estimated to be 180.85/100,000 person-years. This was adjusted as 602.83/100,000 person-years by considering interdonation intervals. The risk of post-transfusion hepatitis B was estimated to be 974 units per one million of whole blood units due to be in window period of infection. CONCLUSION: The estimated seroincidence of HBV among Korean blood donors and thereby the risk of HBV transmission by donated bloods in window period of infection was about 50 to 60 times higher than those of Japan and United States of America.(Korean J Blood Transfusion 10(1): 1-4, 1999)

The polyglandular autoimmune syndrome designates the dysfunction of endocrine and nonendocrine system involving two or more organs on the basis of an autoimmune mechanism. The autoimmune nature of these diseases has been based on the presence of lymphocytic infiltration in the affected gland, organ specific autoantibodies in the serum, cellular immune defects and an association with the HLA DR/DQ genes or immune response genes. This syndrome is usually classified into three classes and their etiology or pathogenesis is still not completely understood. A 28-year-old woman developed vitiligo and insulin dependent diabetes mellitus during the treatment of Graves' disease with antithyroid drug. She had a tendency of spontaneous ketonemia and serum c-peptide levels were low(0.21, 0.16ng/mL: fasting and glucagon stimulated). Thyrotrophin binding inhibitor immunoglobulin and pancreas iIslet cell cytoplasmic antibody were positive. We report here a case of polyglandular autoimmune syndrome, type III manifesting Graves' disease, vitiligo, and insulin dependent diabetes mellitus.

OBJECTIVES: The aim of this study was to know differences of characteristics between presenile and senile patients who were consulted to the department of psychiatry during medical-surgical admission. METHODS: The demographic and clinical data obtained from the medical records of psychiatric consultation in the presenile inpatients with age 50 to 64 years(N=162) and those of the senile inpatients with age over 65 years(N=171) were reviewed and compared. RESULTS: 1) The most common chief complaints for psychiatric consultation in presenile patients were somatic symptoms, anxiety and sleep disturbance in order, while cognitive decline, clouded consciousness and depressed mood were most common in senile patients with statistical significance. 2) The most frequent psychiatric diagnoses after consultation in presenile patients were delirium, mood disorder and substance use disorder in order, while delirium, mood disorder and major neurocognitive disorder were most frequent in senile patients with statistical significance. 3) There were no significant difference in numbers of physical illnesses, while numbers of therapeutic drugs for them were more in senile patients. CONCLUSIONS: Our study found significant differences between presenile and senile patients on psychiatric symptoms and diagnoses in geropsychiatric consultation. Therefore, more subdivided age-specific approach seems to be needed for the geropsychiatric consultation activities.

Primary ovarian choriocarcinoma is an extremely rare germ cell neoplasm, and the prognosis is poor. Especially, the diagnosis of primary ovarian nongestational chori-ocarcinoma can be reliably established in a girl or innocent virgin. We report a case of primary ovarian, nongestational, pure choriocarcinoma in a 16-year-old woman. She died within 1 year after diagnosis in spite of the treatment with surgery and combin-ation chemotherapy.

A fabrication method of inner and outer crown using CAD/CAM is presented. The information of abutment teeth is transferred to a computer through a 3-dimensional scanner. A Konus inner and outer crown is designed on a computer and a real crown is machined based on this design using CAM. This method can save laboratory time and reduce inaccuracies compare to conventional casting procedure. A stone model with six prepared abutment teeth from a patient was used in this study. Three dimensional information from the model was transferred to a computer using a contact type 3dimensional scanner with a 25micrometer accuracy. All margins were identified on a computer image where there is a change in surface taper of a model. To provide a cement space, the image of a inner surface of a Konus inner crown was duplicated 25micrometer apart from the surface of a prepared abutment teeth image. The cement space was 20micrometer at the cervical margin. All Konus crowns were machined with a 10micrometer accuracy. It was concluded that this method can reduce working-time for the laboratory process and increase accuracy. A further research is required to make a simplified process for a more complex prosthesis.

OBJECTIVES: The aims of this study were to know the prevalence of cognitive disorders in patients with thyroid cancer, and identify related variables to them. METHODS: Subjects were consisted of fourty-two patients with thyroid cancer, who were admitted for radioiodine ablative therapy at 6-12 months after total thyroidectomy. The data were obtained from interviews about history and assessments of depression and cognitive function(Korean Version of the Montreal Cognitive Assessment, MoCA-K). RESULTS: 1) Among subjects, those with below 22 of total score of the MoCA-K were twenty-one(50.0%). 2) Upon age, education, Pre-radioiodine therapy thyroid stimulating hormone(TSH), there were statistically significant difference between subgroup with above 23 of the total MoCA-K score and those below 22. 3) The total scores of the MoCA-K in subjects had significant correlation with age, education, comorbidity, Pre-radioiodine therapy TSH, total score of the HDRS-17. CONCLUSIONS: Cognitive disorders were more prevalent among patients with thyroid cancer before radioiodine therapy. Therefore, further study should be needed to clarify the mechanism for the cognitive disorders in thyroid cancer. Furthermore, physicians should pay attention to the cognitive function and prepare preventative measures for cognitive disorder during management of thyroid cancer.

Fungal infection of the central nervous system tends to occur mostly in immunosuppressed patients. In the pediatric population, it is usually seen in severely immunocompromised patients, particulary in children with chronic granulomatous disease and hematopoietic malignancies. Although aspergillosis is considered one of the most frequent agents of mycotic infection of the brain, it is especially rare in the neonatal period, and overwhelming multisystem infection is usually diagnosed postmortem. Manifestations include meningitis, meningoencephalitis, granulomata formation, brain abscess, vasculitis, aneurysm formation, infarct and intracranial hemorrhage. We present a neonate who had brain abscess diagnosed by MRI, and aspergillus was found at surgical exploration. There are very few reported survivors of neonatal aspergillosis. We reported a case of primary multiple brain abscess caused by aspergillus associated with severe hypernatremic dehydration and prerenal azotemia. The patient was treated with amphotericin B combined with flucytosine and itraconazole.
