The cancer of breast is the most common malignancy among women and after cancer of the lung is the second cause of death in females. Thus, early diagnosis and treatment can have a effect significant in prognosis and clinical course of disease. One of the numerous controversial tissues to the clinical management of breast cancers is the role of fine-needle aspiration (FNA) to assess the accuracy and determine the role of FNA in breast cancer diagnosis, we performed both FNA and excisional biopsy in 86 unselected patients with palpable breast masses and correlated the cytologic and histopathologic findings. In our study, FNA had no false-negative and no false-positive results, and the sensitivity of diagnosis of malignant tumors was 88.8%, the specificity of diagnosis of benign lesions was 96.2% and the predictive values were 100%, respectively. On the basis of above study, breast FNA may add a measure of confidence in the diagnosis of benign lesions, provides a safeguard for preventing misdiagnosis of malignant lesion, and might expedite and reduce the cost of managing breast cancer. Also, breast FNA like any diagnostic method depends to individual techniques and continual practice.

A variety of extracranial sites have been described for Meningiomas including the nose, various viscera, skin, eye and extraspinal tissue. Among them cutaneous Meningioma generally occur most frequently on the scalp, forehead or paravertebral areas. We are reporting in this article one case of cutaneous Meningioma in the forehead region with respect by reviewing the literatures is very rare tumor. Our patient is a middle age woman with right forehead mass from two years ago, in the skull X-ray and computerized tomography of our case intracranial lesion is not seen and also there is some thickening involving frontal bone. After the surgical excision of the mass and in the microscopic examination of specimens, histopathologic diagnosis is Meningioma (Meningotheliomatous type) and immunohistochemical study react for epithelial membrane antigen. In the clinical course, extracranial Meningiomas enlarge slowly and are usually cured by simple excision alone but incomplete excision may lead to recurrence, the things have been occurred in our patient.

Background&Objective: Consultation prior to blood donation and screening tests of common blood born diseases such as Hepatitis B,C and AIDS are very important issue in blood quality assurance, therefore we decided to compare frequency of such diseases in blood donors and outpatients admitted in the blood transfusion centers. Materials&Methods: For this purpose the initial tests including HBsAg, HCVAb, and HIVAb were performed on all blood donors and outpatients' blood samples in Gorgan transfusion center by ELIZA methods during 2003 and confirmatory tests including neutralization for HBsAg, RIBA for HCVAb and Western blot for HIVAb performed in condition where ELIZA report was positive. Results: The blood donor in this study had the following positive results: HbsAg 2.5%, HCVAb 3%, HIV 0.35%. The same indeces for the out patients were positive as follow: 13%, 8.3% and 2.04% respectively. The other finding from this investigation indicate that the blood donors positive cases with the ELISA technique were confirmed by Western blot 92%, 20.1% nad 0% for HBSAg, HCVAb, as HIV respectively. The confimatory results of the positive out patient's cases were as follow, 97%, 47% and 60% for HBSAg, HCVAb and HIV respectivley. Conclusion: This study reveals frequency of Hepatitis B and C and AIDS among outpatients which considered being high risk group are more than the blood donors. We conclude that the measurement of HBSAg by ELIAZ methodes in comparision to the HCV and HIV are more accurate.

Background&Objective: The presence of single or multiple nodules within the thyroid gland is a common clinical problem. It is immposible to differentiate benign and malignant follicular neoplasms in cytologic examinations.Estimation of risk of malignancy in thyroid nodules who are cytologically assumped to be follicular neoplasm has a critical importance.The aim of this research is evaluation of diagnostic value of thyroid FNA in follicular neoplasm. Materials&Methods: This survey was done on 476 patients with thyroid nodule whome were biopsied in a 7 years period (in 5th Azar hospital, Gorgan). Standard aspirations and biopsies techniques performed and nessassary smears prepared. Wet-fixed smear glass slides are placed immediately in alcohol (70%) 7-10 slides from the aspiration. The patients with cytologic report whome considered follicular neoplasm followed total thyroidectomy or lobectomy. Results: From 476 patients for thyroid nodules 412 cases(86.5%) are suitable for cytologic evaluation which 312 cases(77.9%) of them were benign and 14 cases(3.3%) were malignant.The rest(77 cases)reported to have follicular neoplsm, this patients also undergone thyroid surgery.The result of histological findings appeared in 32 cases(57.1%) follicular adenoma,15 cases(26.7%) non-neoplastic nodules,5 cases(8.9%) follicular carcinoma and 4 cases(7.1%)follicular type of papillary carcinoma. Conclusion: 9 cases (16%) found malignant among cases which cytologic reports considered as “follicular neoplasms” and subsequently undergone thyroid surgery (consist of follicular carcinoma and follicular type of papillary carcinoma), confirme the importance of histopathologic study of follicular lesions for differentiation between malignant and benign lesions.

Background & Objective: The atherosclerosis of left anterior descending (LAD) coronary artery because of subtending more than 50% of left ventricular myocardial mass, has long been the focus of concern regarding appropriate treatment. This study aimed to evaluate efficacy of Percutaneous Transluminal Coronary Angioplasty (PTCA) with stenting for treatment of proximal LAD disease. Materials & Methods: In this descriptive study, 75 patients with isolated proximal LAD atherosclerotic lesion treated with PTCA and stenting were followed up for 9 months. The stenosis of all patients was documented by coronary angiography prior to enrollment. Exercise tolerance testing (ETT) by Bruce protocol was performed before angioplasty and at the end of follow up period as well. Results: There were 44 (58.7%) males, and 31 (41.3%) females. The mean age of patients was 59.4 (range, 39 to 83 yrs). Clinical outcomes of 73 (97.3%) patients were satisfactory. Only two patients developed re-stenosis during the follow up period. The first patient developed myocardial infarction at the 3rd day of her admission, and the second one had an abnormal ETT after 9 months. Percutaneous coronary revascularization with stenting was performed, and both of them were discharged without any problem. Conclusion: This study demostrated that the nine months prognosis of patients with isolated stenosis of proximal LAD coronary artery that treated by PTCA and stenting was acceptable. This treatment improves clinical status and results in lower hospital adverse event rates and in appropriate clinical outcome.

Background and Objective: Occult hepatitis B infection is a form of hepatitis in which despite of absence of detectable HBsAg, HBV-DNA is present in peripheral blood of patients. The mechanisms which are responsible for progression of OBI yet to be clarified but some investigators believed that the genetics and immunological parameters may are different in resistant individuals and patients. Cytokine network system could be leading alteration in viral immune response. The aim of this study was to investigate the relation between polymorphisms +874 region of IFN-Gama with occult hepatitis B infection. Materials and Methods: In this study, the plasma samples of 3700 blood donors were tested for HBsAg and anti-HBs by ELISA. The HBsAg negative and anti-HBc positive samples were selected and screened for HBV-DNA by PCR. HBV-DNA positive samples assigned as occult hepatitis B infection cases and ARMS-PCR technique were performed to examine the present polymorphisms in +874 region of IFN-Gama genes of patients with occult hepatitis B infection. Results: 352 (9.51%) out of 3700 blood samples were negative for HBsAg and positive for anti-HBc antibody. HBV-DNA was detected in 57 (16.1%) of HBsAg negative and anti-HBc positive samples. Our results showed that there was not any significant difference between patients and control group in polymorphisms in +874 region of IFN-Gama genes. Conclusion: This study showed that there is not any significant difference between polymorphisms in +874 region with IFN-Gama occult hepatitis B infection.
