  • Computer-aided diagnosis of breast cancer is an important medical approach. In this research paper, we focus on combining two major methodologies, namely fuzzy base systems and the evolutionary genetic algorithms and on applying them to the Saudi Arabian breast cancer diagnosis database, to aid physicians in obtaining an early-computerized diagnosis and hence prevent the development of cancer through identification and removal or treatment of premalignant abnormalities; early detection can also improve survival and decrease mortality by detecting cancer at an early stage when treatment is more effective. Our hybrid algorithm, the genetic-fuzzy algorithm, has produced optimized systems that attain high classification performance, with simple and readily interpreted rules and with a good degree of confidence.

  • Observation of elastic fiber's change of mouse TMJ due to several round factor, principally external stimulations, their influence on the TMJ structure's change and the analize of the consecutive evolution of the disease in most important. So, the author believe that the factor of TMJ feature is the elastic feature's change and it's the principal factor of the TMJ disease. For observation of the increase and disposition of elastic fiber that to regulate the elastic feature of tissue and allow it existence. For this propose, observation with histologic methods on 20mouse ICR of 3 days, 1 week, 2 weeks, 3 weeks and 4 weeks. The results were as follow : 1. In the early stage, the condyle of TMJ is originated from cartilage mass, and it's calcification is endochondral. 2. In the early stage, the disc is relatively thin and immature, but in the later stage the fiber is dense and the disposition is most functional. 3. Observation of the early stage, the elastic fiber is a thin fiber that to across antero- posterior direction, but in the later stage elastic fiber are developed, the disposition that in the early stage was perpendicular to articular surface, now in parallel. 4. The elastic fiber was observated most clearly in the retrodiscal tissue. 5. In conclusion, the elastic fiber is observed like a thin fiber 1 week from born, but the fiber to increase the weight and it dispose functionally, and 4 week from born, it can realize the normal function.

  • Objectives : The purposes of this study is to estimate the cost of cancer care after its diagnosis and to identify factors that can influence the cost of cancer care. Methods : The study subjects were patients with an initial diagnosis one of four selected tumors and had their first two-years of cancer care at a national cancer center. The data were obtained from medical records and patient surveys. We classified cancer care costs into medical and nonmedical costs, and each cost was analyzed for burden type, medical service, and cancer stage according to cancer types. Factors affecting cancer care costs for the initial phase included demographic variables, socioeconomic status and clinical variables. Results : Cancer care costs for the initial year following diagnosis were higher than the costs for the following successive year after diagnosis. Lung cancer (25,648,000 won) had higher costs than the other three cancer types. Of the total costs, patent burden was more than 50% and medical costs accounted for more than 60%. Inpatient costs accounted for more than 60% of the medical costs for stomach and liver cancer in the initial phase. Care for latestage cancer was more expensive than care for early-stage cancer. Nonmedical costs were estimated to be between 4,500,000 to 6,000,000 won with expenses for the caregiver being the highest. The factors affecting cancer care costs were treatment type and cancer stage. Conclusions : The cancer care costs after diagnosis are substantial and vary by cancer site, cancer stage and treatment type. It is useful for policy makers and researchers to identify tumor-specific medical and nonmedical costs. The effort to reduce cancer costs and early detection for cancer can reduce the burden to society and improve quality of life for the cancer patients.

  • Recently, the prevalence of bladder cancer is increasing in the Korean society. As the risk factors of bladder carcinoma are variable, the early-stage diagnosis is regarded the best preventive practice. Hematuria is a specific sign of the malignancy as well as a kind of various medication-related adverse reactions. Some anti-coagulation therapy can cause bleedings including hematuria to the patients with cardiovascular diseases such as paroxysmal atrial fibrillation (PAF). Therefore, to the clinical pharmacists working in the anti-coagulation services (ACS), a closer monitoring of patients can give an opportunity to find certain ailments unexpectedly. In this case, a patient with PAF had episodes of sporadic hematuria in the course of warfarin therapy even though with its low levels of INR. An ACS pharmacist found a discrepancy between the bleeding symptoms and INR values, and recommended properly the patient to refer urologist. Fortunately, an early-stage of bladder carcinoma was found then followed by an excision performed to the lesion. Therefore, alert-minded and precise monitoring done by ACS pharmacist could optimize the therapeutic outcomes as well as increase the quality of life of the patient.

  • Oral cavity cancer accounts for approximately 3-4% of all malignancies and is a significant worldwide health problem. The Korea Central Cancer Registry estimates that there will be approximately 1500 new cases of oral cancer in Korea. Oral cancer occurs most commonly in middle-aged and elderly individuals. The majority of oral malignancies occur as squamous cell carcinomas and despite remarkable advances in treatment modalities, the 5-year survival rate has not significantly improved over the past several decades, hovering at about 50% to 60%. The unfavorable 5-year survival rate may be attributable to several factors. First, oral cancer is often diagnosed at a late stage, with late stage 5-year survival rates as low as 22%. Additionally, the development of secondary primary tumors in patients with early stage disease has a major impact on survival. The early detection of oral cancer and premalignant lesions offers the promise to cure chance of oral cancer. The major diagnostics moddalities for oral cancer include oral cavity examination, supravital staining, oral cytology, and optical detection systems. But the clinical finding of oral mucosa is the most important key to confirm the oral cancer until now. The traditional clinical examination of oral cavity can be performed quickly, is without additional diagnostic expense to patients, and may be performed by health care professionals. Therefore, clinicians must be well-acquainted with clinical characteristics of oral cancer and practice routine screening for oral cancer in dental clinic to decrease the morbidity and mortality of disease.

  • Diabetic polyneuropathy (DPN) is the most common form of diabetic neuropathy, and causes a significant morbidity with an impact on the quality of life in the patients with diabetes. Since DPN frequently induces foot deformity and ulceration, which finally leads to foot amputation, the early detection and treatment is very important for the prevention of a permanent structural change. In the early stage of DPN, the diagnostic methods which can evaluate the function or structure of small nerve fibers should be employed because small nerve fibers are first involved in the course of DPN. However, the nerve conduction study cannot reflect the function of the small nerve fibers, and thus, has a definite limitation in the early diagnosis of DPN. For the early detection of DPN, electrodiagnostic data should be interpreted on a clinical context, along with the careful evaluation of the small nerve fiber functions using the tests such as the analysis of intraepidermal nerve fiber density.

  • To complement and develop the Orient Medical Bian Zheng treatmemt(韓方辨證施治), I have observed and analysed 68 persons who have recieved medical treatment because of the epigastric pain. Considering and analysed the Clinical Diagnosis(臨床診斷) and Clinical Bian Zheng(臨床辨證), Clinical Diagnosis(臨床診斷) and Gastroscopic Bian Zheng(微觀辨證), Clinical Bian Zheng(臨床辨證) and Gastroscopic Bian Zheng(微觀辨證), case history, age and sex, I have obtained the conclusion as follows. 1. The frequency of epigastric pain according to the classfication of Clinical Bian Zheng(臨床辨證) most occured in Gi Che Zheng(氣滯證), then in Huh Han Zheng(虛寒證). and least in Wi Youl Zheng. 2. There is no clear connection between the Clinical Bian Zheng(臨床辨證) and Clinical Diagnosis(臨床診斷). 3. The frequency of the epigastric pain according to Gastroscopic Bian Zheng(微觀辨證), mainly occurred in Wi youl Type(胃熱型), Wi Rac Jac Sang Type(胃絡灼傷滯型)and then occurred in Wi Han Type(胃寒型), and least occurred in Wi Rac A Che Type(胃絡瘀滯型) 4. Having observed the relation between the Gastroscopicin Bian Zheng(微觀辨證), and Clinical Diagnosis(臨床診斷) as pathological process, I have obtained the result that Wi Youl type(胃熱型) and Wi Rac Jac Sang Type(胃絡灼傷型) mainly occurred in Erosive Gastritis and Superficial Gastritis at the early stage, and Wi Rac A Che Type(胃絡瘀滯型) occurred in the whole stage among the Wuperficial Gastritis, Atro pic Gastritis, and Erosive Gastritis, Gastric Cancer, and the Wi Han Type(胃寒型) mainly occurred in Atropic Gastritis at the later stage. 5. The relation between Clinical Bian Zheng(臨床辨證) and Gastroscopic Bian Zheng(微觀辨證) do not coincide. 6. Observing the relation between the Clinical Bian Zheng(臨床辨證) and case history, Gi Che Zheng(氣滯證), Huh Han Zheng(虛寒證), Wi Youl Zheng(胃熱證) were commonly seen in the early stage of the case history, and Eum Huh Zheng(陰虛證) and Houl A Zheng(血瘀證) were seen in every stage. 7. Observing the relation between the Clinical Bian Zheng(臨床辨證) and age, Gi Che Type(氣滯型) was mostly seen in the thirties and other Bian Zheng(辨證) was seen after the middle 8. Observing the relation between the Clinical Bian Zheng(臨床辨證) and sex, Gi Che Type(氣滯型) was seen at high ratio in both sexes. 9. Observing the relation between the Gastroscopic Bian Zheng(微觀辨證) and case history Wi Han Type(胃寒證), Wi Youl Type(胃熱型), Wi Rac Jac Sang Type(胃絡灼傷型) were seen in the early stage of the case history Wi Rac A Che Type(胃絡瘀滯型) was mostly seen in the later stage. 10. There was no clear connection between the Gastroscopic Bian Zheng(微觀辨證) and age, sex. Although the examples were not sufficient, recipe regarding the partial variation state of stomach mucos together with Orient Medical Bian Zheng(韓方辨證) treatment seems to be useful in the effective treatment of Bi wi(脾胃) disease besides the epigastric pain.

  • Background: In the absence of routine screening program for cervical cancer in Iran and high rate of diagnosed cancer in its advanced stage, recognition of sociodemographic factors related to delayed diagnosis of cancer in Iran could be helpful in reducing the burden of disease in our community. The aim of this study was to determine the stage of cervical cancer at diagnosis and factors related to delayed diagnosis of cervical cancer in Isfahan, Iran. Materials and Methods: In this cross sectional study women diagnosed with cervical cancer for the first time by histo-pathological examination were enrolled. According to the clinical and paraclinical findings and staging of the cancer, they were classified into early and delayed diagnosis of cervical cancer. Sociodemographic factors were compared in the two groups. Results: In this study of 55 women mean age was $48.3{\pm}12.0.$ According to our classification 6/55 (10.9%) and 49/55 (89.1%) of them had early and delayed diagnosis of cervical cancer. Delayed diagnosis of the cancer was significantly higher in patients with lower degree of education, lower socioeconomic status, having smoker and addict husband and those who did not have a history of Pap smear test (p<0.05). Conclusions: The results of this study indicated risk factors related to delayed diagnosis of cervical cancer. The affected women should be targeted for implementation of specialized educational programmes for improving knowledge and screening test.

  • Tetanus is a fatal disease caused by the infection Clostridium tetani found in animal feces and soil. It is a vaccine-preventable disease and rarely occurs in developed countries. However, approximately 30 cases still occur annually in South Korea. Tetanus, commonly called lockjaw, cause contraction of the masseter muscles in the early stage, resulting in trismus as the first symptom. As it progresses, spasm extends to various muscles in the face, neck, shoulder, and back, leading to distorted facial expression, dysphagia, backward arching of the body, dyspnea, and even death. Early diagnosis of tetanus is critical because it can quickly become fatal if left untreated. We present a case of trismus caused by tetanus and emphasize the importance of early diagnosis of acute trismus.

  • An expert system for stroke diagnosis was designed in this study. The causes of stroke in the central nervous systems are very diverse, symptoms may not appear in the early stage, so diagnosis ran be difficult. Also, doctors who treats patients with stroke must have expert knowledge for the quick and correct impending diagnosis. Therefore, an expert system for assisting the impending diagnosis of stroke has needed to be developed. In addition, the diagnosis system can be used as an simulator for medical students who study neurology. In this study, and diagnosis expert system was developed. It serves a pathological data bus provided by an interface. An inference engine makes an impending diagnosis of stroke possible. We implemented the system using Windows2000 Server, IIS5.0 and ASP.
