  • Fine needle aspiration biopsy cytology (FNA) is an important diagnostic tool in the management of thyroid nodule. Especially, papillary carcinoma of the thyroid has distinct morphologic features that allow a definite cytologic diagnosis with high degree of accuracy. We examined the characteristic cytologic features of 57 cases of papillary carcinoma of the thyroid, and their frequency and diagnostic significance were evaluated. The results obtained are summerized as follows; 1. In pattern of cellular arrangement, papillary structure with or without stroma is predominant feature (96%). 2. In individual cell morphology, grooved nuclei (95%), intranuclear cytoplasmic invagination (89%) and nuclear lobulation (74%) are most frequent and important cytologic findings. 3. Chromatin pattern is usually fine. Coarse chromatin is infrequent finding (37%). Nucleoli are inconspicuous. Cytoplasm us plump and distinctly eosinophilic. 4. Psammoma bodies are identified only in 4 cases (7%), but they are considered as helpful diagnostic features. 5. There are other associated findings including multinucleated giant cells (51%), macrophages (37%) and cystic degeneration (16%).

  • 최근 5년간의 소아의 복부종괴 23예를 발생빈도, 부위 및 방사선학적 소견을 중심으로 비교분석하여 다음과 같은 결론을 얻었다. 1. 전체 23예중 신경아세포종이 6예로 가장 많았고 그 다음이 Wilms 종양 5예, 담도낭종, 난소종양, 수신종 등의 순위였다. 2. 발생연령별로 분석해 본 결과 6세 이하가 78%(14예)를 차지했고 특히 후복강 종양은 6세 이하에 집중되어 있었다. 3. 부위별로는 후복강 종양이 60%(14예)로 가장 많았다. 4. 방사선학적 소견을 분석하여 본 결과 1) 단순 복부촬영상 신경아세포종의 50%에서 특징적인 석회와 음영을 볼 수 있었고 후복강 종양의 대부분에서 비특이적인 석회화 음영을 볼 수 있었다. 2) 초음파 소견상 저에코, 고에코 또는 혼합에코 등의 종괴 내부성상을 알 수 있었으나 종괴의 정확한 해부학적 위치를 파악할 수 없는 경우가 많았다. 3) 경정맥 신우 조영촬영상 신우신배의 비정상적인 소견과 신장의 전위 소견으로부터 신장내 종양과 신장의 다른 부위의 종양을 구분할 수 있었다. 4) 전산화 단층촬영상 종괴 내부의 성상뿐만 아니라 종괴의 해부학적인 위치, 주위 구조와의 관계, 임파절이나 다른 부위로의 전이유무를 알 수 있었다.

  • Background: The objective of this study was to determine a diagnostic classification scheme using a decision tree based model. Materials and Methods: The study was conducted as a retrospective case-control study in Imam Khomeini hospital in Tehran during 2001 to 2009. Data, including demographic and clinical-pathological characteristics, were uniformly collected from 624 females, 312 of them were referred with positive diagnosis of breast cancer (cases) and 312 healthy women (controls). The decision tree was implemented to develop a diagnostic classification scheme using CART 6.0 Software. The AUC (area under curve), was measured as the overall performance of diagnostic classification of the decision tree. Results: Five variables as main risk factors of breast cancer and six subgroups as high risk were identified. The results indicated that increasing age, low age at menarche, single and divorced statues, irregular menarche pattern and family history of breast cancer are the important diagnostic factors in Iranian breast cancer patients. The sensitivity and specificity of the analysis were 66% and 86.9% respectively. The high AUC (0.82) also showed an excellent classification and diagnostic performance of the model. Conclusions: Decision tree based model appears to be suitable for identifying risk factors and high or low risk subgroups. It can also assists clinicians in making a decision, since it can identify underlying prognostic relationships and understanding the model is very explicit.

  • Mahalanobis Taguchi System (MTS) is a pattern information technology, which has been used in different diagnostic applications to make quantitative decisions by constructing a multivariative measurement scale using data analytic methods. In MTS approach, Mahalanobis distance (MD) is used to measure the degree of abnormality of patterns and principles of Taguchi methods are used to evaluate accuracy of predictions based on the scale constructed. The advantage of MD is that it takes into consideration the correlations between the variables and this consideration is very important in pattern analysis. The purpose of this study is constructing admission diagnosis system and define the effect of admission requirements for student's academic accomplishment.

  • The introduction of high-resolution CT (HRCT) in recent years has improved the ability of radiologists to detect and characterize the diffuse infiltrative lung disease (DILD). The detection and diagnosis of diffuse lung disease using HRCT are based on the recognition of specific abnormal findings. In this article, pattern recognition of HRCT findings is reviewed in the differential diagnosis of diffuse infiltrative lung disease. In general, HRCT findings of lung disease can be classified into four categories based on their appearances. These categories consist of (1) nodules and nodular opacities, (2) linear and reticular opacities, (3) increased lung opacity, and (4) decreased lung opacity, including cystic lesions.

  • Objective : The purpose of the present study was to report the improvement of functional abdominal pain in a patient treated with a herb medication based on a disease pattern identification diagnostic system under the provision of Shanghanlun (DPIDS). Methods : According to DPIDS, the patient was diagnosed with Taeyang-byung, no. 25 provision, and was administered with Gyejiyimahwangyil-tang herb medication for 60 days. The severity of the abdominal pain was assessed with the five-point Likert scale. Results : The abdominal pain in the patient disappeared following treatment with Gyejiyimahwangyil-tang, which is described in the 25th provision of Shanghanlun. Conclusions : The present case report suggests that '瘧', a word in the 25th provision of Shanghanlun may indicate severe abdominal pain at nighttime and not just malaria.

  • The morphology, taxonomy, and distribution of species belonging to the diatom family Rhizosoleniaceae were studied from the marine coastal waters of Korea. Rhizosolenid diatom taxa were collected at 30 sites from September 2008 to February 2010 and were analyzed by light and scanning electron microscopy. We identified 6 rhizosolenid genera, including Rhizosolenia, Proboscia, Pseudosolenia, Neocalyptrella, Guinardia, and Dactyliosolen. We describe 5 genera in this study, except Rhizosolenia. Five genera were compared in detail with congeneric species. Six genera within the family Rhizosoleniaceae were divided into two groups based on morphological diagnostic characters including valve shape, areolae pattern, the shape of external process, and girdle segments in the column. The first group had a conoidal valve and loculate areolae, which comprised Rhizosolenia, Proboscia, Pseudosolenia, and Neocalyptrella, and the second group of Guinardia and Dactyliosolen showed a flat or rounded valve and poroid areolae. Important key diagnostic characters were based on valve shape, areolae pattern on the segment, external process, position of the tube, and the valve margin. D. phuketensis was new to Korean coastal waters.
