RESUMEN
This study reports the detection and genotyping of the first clinical case of bovine anemia due to Theileria orientalis group (BATOG) in non-grazed dairy cow in upper Korea. Blood and serum tests revealed anemia and hyperbilirubinemia from animal showing clinical symptoms, and later confirmed as piroplasmosis-positive. Follow-up surveillance on the herd revealed 2 asymptomatic cows with anemia. The three animals were confirmed theileriosis-positive and genotyping revealed the clinical and one of the asymptomatic cases have Chitose, while the other has Ikeda genotype. Clinical BATOG cases were rarely reported worldwide, and asymptomatic animals left untreated could serve as parasite reservoir.
RESUMEN
BACKGROUND/AIMS: We studied the prevalence of chronic hepatitis B, C and abnormality on liver function among the population in northwest area of Chungnam. METHODS: We have reviewed 40,112 adults who had received medical examination at health promotion center in Dankook university hospital. We studied them retrospectively about HBsAg, HBsAb, anti-HCV, and liver function test (LFT). RESULTS: Among the study subjects, 22,936 men and 17,176 women were involved. The overall seroprevalence of HBsAg was 4.2%. The prevalence in men (4.5%) was higher than that of women (3.7%) (p<0.001). The seroprevalence of HBsAg in their age was 5.1% in the 5th decade, 4.2% in the 2nd decade, 4.1% in the 4th decade, and 4.1% in the 6th decade. The overall seroprevalence of HBsAb was 65.1%. The overall seroprevalence of anti-HCV was 0.7%. After we reexamined them with HCV RNA or RIBA (Recombinant Immunoblot Assay), the prevalence of chronic hepatitis C was 0.09%. The LFT abnormality in total subjects was 11.4%. The LFT abnormality of chronic hepatitis B and C subjects was 21.72% and 63.2%. CONCLUSIONS: The prevalence of chronic hepatitis B and C was lower than that of previous studies. The prevalence of chronic hepatitis B in the 2nd decade was still high.

We report a case of Bowen's disease in a 63-year-old male patient who presented with a 15x10cm-sized, large erythematous, scaly plaque on his back. Histopathologic examination revealed Bowen's disease. The skin lesion was improved after treatment with modified phenol peeling. Modified phenol peeling of Bowen's disease can be an alternative method of therapy for those lesions which are too large for excision and primary closure.

RESUMEN
Cranioplasty is a method of the correction of defects and deformities of the bony walls protecting the brain. If defects and deformities are located in the frontal region, the correction is often necessary for cosmetic reasons. Rib, iliac bone and calvarium may be used for frontal cranioplasty. Rib bone and iliac bone have the donor morbidity and may result in cosmetically unacceptable contour. Calvarium is superior to the ilium and rib for it causes less donor site morbidity, it's consistency is harder than others and postoperative bone resorption is less. But it is difficult to mold and shape at the operative table, because the contour of parietal bone is different from that of frontal bone. For the last recent two years, we have performed frontal cranioplasty in five patients with frontal defect or deformity, by using calvarial bone graft that is molded with multiple osteotomy and microplate. Follow-up period ranged from 6 to 18 months with a mean of 12 months. There were no complications. This technique was simple and we could get aesthetically good contour on the frontal area.

We observed a 25-year-old male patient who had developed juvenile rheumatoid arthritis(RA) associated with alopecia areata at 14 years of age. When he received treatment for RA, his symptoms of RA and hair loss improved at approximately the same time. One year later, as the symptoms of RA aggravated, the hair loss had progressed eventually to alopecia universalis(AU). Thus we suggest that RA and AU may be associated with a common immunologic factor in etiology of the two diseases.

OBJECTIVES: In Korea, as in most countries, there will be a sharp increase in the number of dementia patients in the near future. However basic data on dementia prevalence, which is important in defining epidemiologic characteristics and in implementing preventive strategy, are limited. This study was conducted to estimate the prevalence rate of dementia in the urban elderly aged 65 or older in Kwangmyung, Korea. METHODS: A two phase design was used for case finding and case identification. In phase I, a representative sample aged 65 or older was selected and interviewed by door-to-door survey with a Korean version of the Mini-Mental State Examination (K-MMSE). In phase II, Of the 946 subjects interviewed in phase I, 356 elderly were randomly selected disproportionately according to K-MMSE score. Of these elderly, 223 (61.5%) underwent standardized clinical evaluations, including psychiatric interview, neurological examination, and neuropsychological assessment. Dementia was diagnosed by the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) criteria. The diagnosis of Alzheimer's disease (AD) was made by National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer's Disease and Related Disorders Association(NINCDS-ADRDA) criteria and vascular dementia (VD) by DSM-IV. RESULTS: The overall weighted prevalence rate of all dementia among Kwangmyung residents aged 65 or older was 12.8%(age-adjusted rate: 13.0%, 95% Confidence Interval[CI]: 10.6-15.3%). Women had much higher prevalence rate than men even when age was controlled(15.9%[95% CI 12.6-19.2%] vs 7.5%[95% CI 4.6-10.4%]). The rates of dementia were 5.2%, 12.2%, 17.0%, and 34.3% for the age groups of 65-69, 70-74, 75-79 and 80 and over, respectively. The rate of AD appeared to be slightly higher than that of VD(5.2% vs 4.8%), though not statistically significant. Most of the cases(69%) were mild dementia according to CDR(<1) in these subjects. CONCLUSIONS: These results showed that the prevalence rate of dementia among urban elderly in Korea appears to be higher than those of other Asian countries.

Herein, we report a case of multiple myeloma with multiple plasmacytomas of thyroid, lung, lymph nodes and adrenal gland, who presented as upper airway and esophageal obstruction with vocal cord palsy. An 80-year-old women complained of dysphagia, hoarseness and anterior neck mass. Ultrasonography of the neck showed huge inhomogeneous solid mass involving left thyroid lobe and isthmus with several lymphadenopathy along the both upper deep cervical chain. Chest CT scanning revealed 4x3 cm sized, low density mass in posterobasal segment of the right lower lobe with both lower paratracheal lymphadenopathy, and abdominal CT scanning revealed 4.5x4.5 cm sized round low density mass in left adrenal gland. Serum and urine electrophoresis was normal and immunofixation of serum and urine was negative. Bone marrow smear and a bone scintigram revealed no abnormality, but iliac bone marrow biopsy revealed infiltration of abnormal plasma cells. Histologic and immunohistochemical examinations of the thyroid and lung mass revealed monoclonal proliferation of plasma cells of kappa light chain. After local irradiation of the neck with parenteral dexamethasone injection, anterior neck mass was much diminished in size, but 2 weeks later she had a pneumonia with fatal outcome.

PURPOSE: p53 gene mutations, one of the most common alterations found in human tumors, has also been detected in gastric carcinoma, and shown to have a crucial and early role in gastric carcinogenesis of intestinal type and mainly associated with tumor progression in the cancer of diffuse type. We tried to investigate the frequency of p53 mutations in 27 gastric carcinomas. MATERIALS AND METHODS: Fresh tumor tissue from a series of gastric carcinoma was screened for p53 mutations by polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) with silver staining and confirmed by direct-sequencing in 27 cases of gastric carcinoma. Immunohistochemical method for p53 protein accumulation was also performed in the same cases. RESULTS: Immunohistochemistry revealed 20 of 27 cases of gastric carcinoma, positive for p53. PCR-SSCP analysis of p53 exons 5-8 detected mobility shift in 4 out of 20 p53-positive tumors; three from exon 5 and the other from exon 7, respectively. DNA sequencing of exon 5 showed CGC to CAC point mutation in one of three cases; exon 7, ATC to AAC point mutation. It seemed that there was no correlation between genetic alterations of p53 gene detected by PCR-SSCP and expression of p53 protein by immunohistochemistry. CONCLUSIOAS: Our results suggest that mutations of the p53 gene are rare genetic events in carcinogenesis of gastric carcinomas. There was discrepancy between mutations screened by PCR-SSCP and overexpressions in immunohistochemical staining.

Hereditary anhidrotic ectodermal dysplasia is a rare hereditary condition in which certain structures derived from the ectoderm are undeveloped or underdeveloped, although, on a rarity, mesodermal or endodermal derivatives may be associated. Recently, we enperienced 3-cases of anhidrotic ectodermal dysplasia in 3 months male infant and in brothers aged 4(1/2) months and 22 months. They had abscence of sweating, hypotrichosis and defective dentition, which was characteristic features of this disorder. They seemed to be inherited a sex linked recessive fashion in their family ground. We established the diagnosis with this clinical features, their familial history, and skin biopsy. The first case of these was associated with congenital heart disease, a mesodermal derivative. But, we couldn't explain the associations of this anhidrotic ectodermal dysplasia and the occurance of C.H.D.

A case of carbuncle of the left kidney is reported with a review of literature. The patient reported herewith was 19 years old student, who complained of fever, vomiting and the tenderness in the left flank. His urine specimen showed numerous pus cells and hematological studies revealed leucocytosis. On intravenous pyelography the left kidney appeared normal. However, dye excretion by the right idney was delayed and there was a compression deformity of the lower calyx and extravasation of the dye into the renal parenchyma of the lower pole. The history and clinical findings seemed consistent with a renal carbuncle. A nephrectomy was performed as the procedure of choice. The specimen revealed, on cut surface, a large necrotic area measuring 2.1 cm in diameter, which communicated with the lower calyx. Culture of the abscess disclosed colonies of staphylococcus.
