Purpose : The purpose of this study was to research whether measurement of cow's milk specific IgE on the newborn would be helpful in the diagnosis of cow's milk allergy. We tried to find out the relation between cow's milk specific IgE and other allergy diseases by following up cases. Methods : We reviewed clinical features of 87 episodes in infants less than 4 weeks old who were positive in cow's milk specific IgE test. For the study group, history taking, physical examinations, elimination and cow's milk specific IgE tests were carried out. We investigated the connection among cow' milk specific IgE, allergic disease and family history in 40 of 87 patients we could follow up on. Results : The mean age of the study group was $17.2{\pm}5.4days$. The subjects were classified in four groups according into allergens : 87 milk allergy positive patients, 24 casein positive, 38 ${\alpha}$-lactoalbumin positive, and 75 ${\beta}$-lactoglobulin positive. The number of patients who had follow-ups for more than 6 months to was 40(45.9 percent). The patients whose parents had allergic disease numberred 10(25 percent). Fiften patients had allergic diseases, 4 had asthma and 11 atopic dermatitis. According to the follow-up study, there is a significant relation between casein positive patients and allergic disease. But there is no statistical and significant relation between cow's milk specific IgE and a family history of allergic disease. Conclusion : For the newborn babies, elimination tests and cow's milk specific IgE tests can be useful in the diagnosis of IgE-mediated or mixed milk allergies.

Radiotherapy, as a major 3 standard treatment for cancer, traditionally it has been useful treatment that aim of curative or palliative setting. In addition to some proliferative or inflammatory benign disease are also included in field of radiotherapy. Unlike cancer, in the case of benign disease, it shows good treatment result from usage of some medication, conservative management or surgery. But if fail of these treatment or impossible, low dose radiotherapy is use adjuvant or replacement treatment so that there are no harmful side effect result in safety and easy management for reduce pain or recurrence. Recently, the technical advances in radiotherapy that have been achieved make preservation of normal tissue and the clinical application of high precision radiotherapy focus to selective lesions is possible, and it makes useful treatment in senile patients especially.

Pleural masses may be caused by various conditions, including benign and malignant neoplasms and non-neoplastic tumorlike conditions. Primary pleural neoplasms include solitary fibrous tumor, malignant mesothelioma, and primary pleural non-Hodgkin's lymphoma. Metastatic disease is the most common neoplasm of the pleura and may uncommonly occur in patients with hematologic malignancy, including lymphoma, leukemia, and multiple myeloma. Pleural effusion is usually associated with pleural malignancy. Rarely, pleural malignancy may arise from chronic empyema, and the most common cell type is non-Hodgkin's lymphoma (pyothorax-associated lymphoma). Non-neoplastic pleural masses may be observed in several benign conditions, including tuberculosis, pleural plaques caused by asbestos exposure, and pleural loose body. Herein, we present a review of benign and malignant pleural neoplasms and tumorlike conditions with illustrations of their computed tomographic images.

Purpose: Previous studies have not showed consistent results for the level of expression of sodium/iodide symporter (NIS) in thyroid diseases, especially malignant tumor. We undertook this study to evaluate the distribution of NIS expression in malignant thyroid diseases and compare with that in benign thyroid disease. Materials and Methods: Total patients were 119 cases (Men 15, $48{\pm}13$ yrs). Total number of samples were 205 pieces. In malignant thyroid disease, there were 153 samples: 90 in papillary carcinoma, 4 in follicular carcinoma, 2 in medullary carcinoma and 57 in metastatic lymph node. In benign thyroid disease, there were 52 samples: 36 in goiter/cyst, 11 in thyroiditis and 5 in follicular adenoma. Using immunohistochemical methods, we probed 205 samples with monoclonal anti-NIS Ab. Grading of staining was stored as 0 (negative or absent), 1 (weakly positive), 2 (moderately positive) or 3 (strongly positive). Expression rate (ER) of NIS positivity in individual disease entity was expressed as percentage of total number divided by number in 2 plus 3 grade. Results: ERs of malignant thyroid diseases were 63% in papillary carcinoma, 81% in metastatic lymph node, 71% in follicular carcinoma and 100% in medullary carcinoma. ERs of benign thyroid disease were 53% in goiter/cyst, 64% in thyroiditis and 40% in follicular adenoma. ER of malignant thyroid diseases was higher than benign thyroid diseases (71% vs 54%). Grading of NIS expression in papillary carcinoma or goiter/cyst was heterogeneously distributed in considerable cases. Normal tissue also showed heterogeneous distribution of NIS expression, which was not correlated with that of primary lesion. Conclusion: In papillary thyroid carcinoma, distribution of NIS expression was heterogeneous and increased, and not different compared with that of benign thyroid disease.

Purpose: The test had been applied for outpatient by end of 2006, however, it has been included in the medical examination since January 2007, as demand and interests have been gradually increasing in the thyroid gland disease and cancer. thus, we would necessarily evaluate usefulness of the test by comparing the number of patients who are diagnosed as "benignancy" by the medical test with the number of outpatient who attend and are diagnosed as autoimmune thyroid disease among the benign patient, in samsung medical center for a certain period. Materials and Methods: Based on the result for Anti-TPO Antibody test by RIA for the 12,937 patients in samsung medical center from October 2007 to March 2008, for six months, benignancy rate classified by sex and age is measured statistically and number of the patients who are diagnosed as autoimmune thyroid disease are kept tracked on. Results: According to the analysis of the Anti-TPO antibody test 1,135 of 12,937, which is 8.77% are benign and 218 treated patient of them, which is 19.2%, were diagnosed as autoimmune thyroid disease. Conclusions: Based on the statistics, usefulness of the test seem to have co relationship with derivation of autoimmune thyroid disease. this is 19.2% of probability relatively high. this figure, however, does not have strong relationship with specialty of the disease. Thus screening test seems to have somewhat effectiveness, considering other experiments and their margin.

성대결절, 폴립, 부종 등은 성대의 남용이나 과용등의 성대손상이 그 공통된 주된 원인으로 거론되고 있다. 하지만 음성치료를 비롯한 보존적 치료에 대한 반응이 서로 상이하며, H＆E 염색을 이용한 병리조직학적인 감별이 곤란하여 진단에 혼돈이 있으며, 치료의 방침을 결정하거나 예후를 예측함에 있어서도 어려움이 있다. 양성성대질환은 기저막부 위와 세포외 간질에 주된 변화가 발생함이 알려져 있고, collagen type IV의 발현양상이 성대결절과 폴립에서 서로 다름에 대하여는 보고된 바 있으나 기타 점막하층의 골격유지를 주기능으로 하는 대표적 세포외간질인 collagen subtype에 대하여는 아직 보고된 바가 없는 실정이다. Collagen 발현의 차이를 연구하는 것은 상기질환의 병인을 이해하고 질환분류의 guideline을 제시하며 나아가 적절한 치료방범을 제시하는 데에 큰 의미가 있을 것으로 기대된다. Paraffin에 고정되어 있는 5례 이상씩의 성대결절과 성대폴립, 육아 종 및 라인케씨 부종 조직을 collagen type I부터 VII에 대하여 peroxidase kit를 사용하여 염색한 후 각 군간에 collagen 분포양상과 발현정도에 차이가 있는가 비교하였다.

Sensitivity of anti-Texoplasma antibody (IgG) test by enzyme·linked immunosorbent assay (ELISA) was evaluated in comparison with indirect laten agglutination (ILA) using 2,016 paired human samples of serum and cerebrospinal quid (CSF) . The samples were collected from neurologic patients in Korea with mass lesions in central nervous system(CNS) as revealed by imaging diagnosis(CTIMRI). When the sera were screened for anti-Toxoplasma antibody by ILA, 76 cases (3.8%) were positive (1:32 or higher titers). In the pairs samples of CSF, no positive reactions were observed. When ELISA was performed using PBS extract of Percoll purified tachysoites as antigen, cut-off absorbance was determined as 0.40 for serum and 0.27 for CSF tests. The antibody positive rates by ELISA were 7.0% in serum and 5.6% in CSF Of them, 40 cases(2.0%) showed positive reactions in both serum and CSF, The antibody positive rates were higher in groups older than 40 years, The rates were higher in male(4.7% by ILA, 8.3% by ELISA) than in female(2.2% by ILA, 5.0% by ELISA). The rates in CSF showed no such sex difference. ELISA showed twice higher positive rates when serum was tested, and was sensitive enough to detect specific antibodies in CSF. Etiologic relations between positive antibody tests and CNS lesions remained unknown.

Posterior canal benign paroxysmal positional vertigo (PCBPPV) is the most common disease among patients who visited the st. Carollo hospital dizziness center with the head suddenly feeling rolling or rotational dizziness caused by head and body movements. Most patients showed improvements in symptoms after a single treatment. On the other hand, there are more causes requiring multiple treatments. This study examined the factors affecting the canalithiasis repositioning maneuver for symptom recovery of dizziness, which is posterior BPPV. Dizziness patients who visited the dizziness center of PCBPPV were classified. From March 2008 to November 2010, the cure rate of 165 posterior BPPVs patients was investigated. The success rate after the first, second, third, and further treatments was 57.6%, 17.6%, 10.3%, and 14.5%, respectively. The factors affecting treatment of PCBPPVs included traumatic, medical disease, cerebral infarction, small vessel disease, vestbro basilar artery insufficiency (VBI), cerebrovascular disease, brain disease, and vestibuloplasty (P<0.05). Vomiting, nausea, and syncope can be treated easily by considering the factors affecting these treatments. If the related diseases are combined with the treatment of the canalithiasis repositioning maneuver for symptom recovery of dizziness, the results will show an improvement in daily life that is free from painful dizziness.
