Background and Objectives:Infection of pleural fluid is a common disease and because of antibiotic administration, the microbiology of this fluid has changed. The aim of this study was to determine the common bacteria and suitable antibiotics for treatment in pleural effusion (PE).
Materials and Methods: In this cross sectional study, 1210 samples with exudative features were cultured for possible growth of microbial pathogens and then examined for antibiotics sensitivity. Samples’ characteristics were then analyzed according to the age and sex difference.
Results: Among 1210 exudative pleural effusions, 38.2% were obtained from females and 61.8% from males. Of 142 pleural fluid samples, 11.7% had a positive culture. Aerobic gram negative organism was the most common type among the other samples with a prevalence of 52% followed by aerobic gram positive (25.3%), non- aerobic gram negative (15.7%), non- aerobic gram positive (6.2%) and fungi (0.8%). E. coli, Staphylococcus Aureus and Acinetobacter baumannii were the most common types of organism among adult population.
Conclusion:Aerobic gram positive bacteria had the highest prevalence among the pathogens, and cephalosporins, aminopenicillins and β-lactams were the most effective antibiotics for their treatment.

Salivary gland tumors accounts for less than 1% of all tumors. Minor salivary gland tumors (MSGTs) are uncommon and make up about 10% of all salivary gland neoplasms. The clinical and histopathological distribution of these tumors vary geographically. A case of a 38 yr old man with a minor salivary gland mass at chin region isreported here. The tumor invaded into the anterior surface of the mandible bone and the surrounding soft tissues. The tumor was resected completely with a safe surgical margin of soft tissue and adjacent bone. Histologically, the tumor is characterized by a biphasic pattern, composed of admixture of epithelial and stromal components, associated with cytological atypia and prominent mitoses. The stromal elements are myxoid, chondroid, and osteoid. The chondroid component is more abundant and shows more atypical changes. Overall, the findings were interpreted as malignant pleomorphic adenoma of minor salivary glands of buccal mucosa.

Background and Objective: Opportunistic infections are the leading cause of death among patients subjected to the human immunodeficiency virus (HIV) infection and acquired immune deficiency syndrome (AIDS). The aim of this study was to compare the seroprevalence of Cytomegalovirus (CMV) and toxoplasmosis infection in newly diagnosed HIV infected patients with healthy controls and it’s correlation with CD4+ cell counts (CD4+).
Materials and Methods: A case controlled study was carried out to investigate CMV and toxoplasmosis serology among newly diagnosed HIV infected patients referred to University affiliated hospital in Tehran and compared them to healthy subjects as control. A total of 100 HIV positive patients and 100 healthy controls were recruited. Clinical characteristics and CD4+ cell counts were evaluated. The statistical package SPSS 17 for windows was used for analysis.
Results: Patients with HIV infection had a significantly higher positive serology for CMV than healthy controls (100% vs. 93% P<0.05). There was no significant difference between HIV positive and HIV negative patients in terms of toxoplasmosis serology. There was no significant difference between males and females with respect to CMV or toxoplasmosis serology.
Conclusion: CMV and toxoplasmosis infection are highly prevalent among HIV infected patients and also healthy controls, with a higher seropositive rate of CMV in HIV cases.

Background & Objective: There are many common infections and inflammations among people over the world. This demands an affordable and reliable test with high sensitivity/specificity to predict or confirm the diagnosis of such cases in routinely clinical practice. In the present study, we aimed to find any potential correlation between serum levels of GGT and CRP- Q and/or hs- CRP and WBC count as the well- known markers of inflammation in human body.
Materials and Methods: Through a cross- sectional study, serum levels of CRP-Q, hs- CRP, and GGT, in addition to WBC count were measured in 1,500 healthy people, referred to Blood Transfusion Organization from across the country. Data were analyzed after the patients were checked by physical examination for ruling out the presence of any inflammation or other illness. Serum levels of GGT, CRP- Q, hs- CRP, and WBC count were analyzed by SPSS for windows version 16.
Results: Analysis showed a positive linear correlation between CRP- Q and hs- CRP with GGT also confirmed by non- parametric tests.
Conclusion: Serum GGT may be an inflammatory index and a useful marker in approaching to inflammatory diseases.
