Background and Aim: Fine Needle ASPIRATION Biopsy is an effective diagnostic method in the field of medical pathologies. Easiness, accuracy, validity and usefulness of this method have been verified frequently. This method is useful not only for soft tisse or even intraosseous lesions, but also recurrence of tumors (metastasis), resistence to treatment, verification of malignancy, differentiation between malignancy and benignment and determination of organisms causes infection. Unfortunately the use of this method is not common in dental pathology. So this study intendes to show the diagnostic value of FNA specially for intraosseous lesions causing jaw radiolucency.Methods and Materials: This investigation consisted of 80 patients who were referred to Taleghani General Hospital who were then referred to the pathology or surgery departments at Shahid Beheshti dental school.Cases consist of 29 females (36.25) % and 51 males (63.75%). Sampletaking was conducted using a 10 cc, gauge 19 syringe.Results: Results show 90% sensitivity and 75% specificity for jaw radiolucent lesions in FNA method. Correlation between FNA and jaw radiolucencies was significant (P<0.001) and it's power was at equal accepctable level according to cramer's V (phi - cramer's =0.623). Based on FNA cytology power, lesions with positive predictive value of 78.30 had a microscopic view compatible to the findings of other similar studies.Conclusion: FNA can be used as a reliable method for rapid, early and in expensive diagnosis, resulting in an on time, and appropriate treatment plan.

SV ASPIRATION is a potential test for the diagnosis of partial EDO. This procedure confirms the presence of intact spermatogenesis, and rules out more proximal obstruction, obviating the need for testicular biopsy. In addition, SV ASPIRATION can be performed without anesthesia or X-ray in an office setting, and use of dye or contrast medium is not necessary.  

Introduction: Thyroid nodules are important because of the risk of malignancy. Fine needle ASPIRATION (FNA), the first diagnostic method in assessment of cytology of thyroid nodules, is a simple, available and cost-effective technique. The aim of this study was to compare the quality of cytomorphology sample, number of cells, the quality of architecture of thyroid papillae and follicles in FNA and fine needle non-ASPIRATION (FNNA) techniques. Material and Methods: 200 patients of Shariati hospital, with palpable thyroid nodules, 1 to 4 cm in size, were recruited. FNA and FNNA techniques were applied to each patient. In a single-blind setting, all specimens were examined by the same cytopathologist. The specimens were scored (0, 1 or 2) on the basis of background blood or clot, number of obtained cells, preserved architecture of papillae and follicles and cellular degeneration. Nonparametric methods were used to compare scores of the two techniques. Results: 200 patients (162 female, 38 male) were entered the study. Specimens from 43 patients were inadequate. In the remaining 157 patients there was no statistically significant difference between average scores in the quality of cytomorphology sample, number of cells, quality of architecture of thyroid papillae and follicles and cellular degeneration in FNNA and FNA. Conclusion: It seems that FNNA is not superior to FNA in the cytopathologic studies of thyroid nodules and there is an agreement between two methods.

Background & Objective: Sellick's maneuver is a routinely used technique for the prevention of pulmonary ASPIRATION of gastric contents during anesthesia. The rationale for the application of cricoid pressure necessitates that it is applied at the loss of consciousness during rapid sequence induction. Cricoid pressure therefore, may be fully applied at a level of anesthesia where AWARENESS, and possibly recall, of the: maneuver occurs.Materials & Methods: This study was setup to determine the frequency of AWARENESS and recall Sellick's maneuver following 100 patients (ASA I, II) who candidates for lower extremity surgery were randomly enrolled in this prospective study. After induction of anesthesia and application of cricoids pressure, symptoms of AWARENESS and recall were recorded. Data were analyzed by SPSS software and Spearman correlation.Results: The frequency of AWARENESS and recall were 45% and 16%respectively.The frequency distribution of AWARENESS severity based on grade 1, 2 and 3 were 16%, 6% and 1% respectively. The frequency distribution of recall severity based on mild, moderate and sever were 15%, zero and 1% respectively. The correlation between AWARENESS severity and recall severity was statistically significant (P<0.05).Conclusion: Due to high frequency of AWARENESS and recall following Sellick's maneuver and its complications, it is available to revise the procedure of this maneuver and in particular the accurte time in its application.

In this study, we investigated the value of cytologic evaluation of ovarian cysts. In a prospective cross-sectional study, we compared cytologic results with pathologic findings in 55 patients with apparently benign ovarian cysts. For functional ovarian cysts, cytology had a sensitivity of 100% and specificity of 90.4%. In endometriosis, sensitivity and specificity of cytology were 66.3% and 100% respectively. In dermoid cyst, sensitivity and specificity of cytology were 100%. In mucinous cysts, we found sensitivity of 90.4% and specificity of 100%. Therefore, in patients with apparently benign ovarian cysts, especially in the centers without adequate equipment or trained personnel for laparoscopic ovarian cystectomy, we can evaluate the ovarian cysts by cytologic ASPIRATION and avoid unnecessary laparatomy especially in infertile women.
