Background and Objectives: Complement proteins are some of the most important plasma proteins of the innate immune system. Impaired immune function is reported in subjects who are iron deficient, and there are documents that these patients are prone to infection. This study was conducted to show whether serum C3 and C4 complement change in adult nonpregnant female with iron deficient anemia or not. Methods: Forty five normal subjects and 45 iron deficient anemia (hypochrom microcytic) cases were entered in this case and control study by using patients’ clinical history and also results of CBC, Serum ferritin, iron and total iron binding capacity. Serum C3, and C4 were measured in case and control subjects with nephlometry method, finally comparison between result of patients group and control group was done with using suitable statistical test. Results: Mean serum C3 and C4 in patient group was 1.28 ± 0.81 and 0.28 ± 0.23 g/L respectively and for control group was 1.39 ± 0.87 and 0.35 ± 0.25 g/L respectively. Although serum complements were slightly lower in patient groups in compared to control group but this differences was not meaningful with t test. Conclusion: This study showed serum C3 and C4 complements levels were not changed in iron deficiency anemia.

Background & Objectives: Cancer is a serious problem for human being and is becoming a serious problem day-by-day .A prerequisite for any therapeutic modality is early diagnosis. Automated cancer diagnosis by automatic image feature extraction procedures can be used as a feature extraction in the field of fractal dimension. The aim of this survey was to introduce a quantitative and objective mathematical method for pinpointing the differences between malignant and non –malignant epithelial cells in urine cytology by the use of software analysis. Materials & Methods: Forty-one positive urine cytology and 33 negative subjects from Pathology Department of Imam Khomeini Hospital, Urmia, Iran (2003-2007) were selected at random. Digitalized images were prepared by the use of objective 100X (a digital video head) which subsequently were processed by the BeonitTM software version 1.3 (Tru Soft International inc. USA) to measure fractal dimension of nuclear boundaries. Results: Findings revealed statistically significant differences between fractal dimensions of nuclear boundaries of cancerous and non-cancerous smears (P=0.001). Study had selected a cut-off point to (1.732 ± 0.006) to discriminate malignant and non-malignant epithelial cells in urinary smears. Conclusion: Based on diagnostic accuracy measures (sensitivity and specificity), probability of disease measures (predictive value of a positive and negative test results), and likelihood ratio of positive and negative tests, it seems fractal dimension of nuclear cell boundaries for urinary smears can be used as a feature extraction in the field of automated cancer diagnosis.

Background and Objectives: Toxoplasmosis has become one of the more frequent opportunistic infections and the most common cause of focal brain lesions complicating the course of AIDS. However, there is a little information about the frequency of the toxoplasmosis in various regions of Iran. At the present study, we evaluated the prevalence of toxoplasmosis in patients with AIDS in Mashhasd (Northeast Iran). Material and Methods: Overall, 258 suspected patients with CD4+ T-cell count and clinical manifestation for HIV infection were referred from Infectious Disease Center to Imam Reza Hospital in 2009. These patients were examined by ELISA, western blot method and tested by P24 antigen. HIV positive patients (n=121) were entered in this cross-sectional study and investigated for IgG and IgM anti- Toxoplasma antibodies with ELISA. Results: The mean age of the patients was 35.83 + 6.75 yr. 83.5% of the patients were intravenous drug misuse. The IgG anti-Toxoplasma antibodies were positive in 46 (38.01%) patients, while IgM antibody was detected in 3 cases (2.5%). Conclusion: The rate of toxoplasmosis infection in HIV positive patients is high. Therefore, immediate treatment of these patients is essential in rising specific antibody cases that may cause toxoplasmic encephalitis resulting from its reactivation.

Background and Objectives: The molecular genetic of the human herpes virus 8 (HHV8) has now been characterized the pathogenesis of kaposi sarcoma (KS). This study attempted to determine the rate of HHU-8 infection in KS in an Iraniann cross sectional study. Method & material: In this cross-sectional study, we used paraffin-embedded specimens of 54 clinically well-characterized kaposi sarcoma cases. Routine streptavidin- biotin- peroxidase immunostaining with diaminobenzidine was performed on paraffin-embedded tissue of 54 KS cases using a monoclonal antibody directed against the c-terminum of the latent nuclear antigen-1 molecule of HHV-8 (colone 13B10; Novocastra) at 1:50 dilution. Result: Positive HHV8 nuclear staining was detected in the nuclei of the spindle cells and endothelial cells of the vascular channels in about 88.9%. (48/54) of all cases and in 90.56% (48/53) of cases with presence of residual tumor in specimen (1 of 54 paraffin blockes has no residual tumor). HHV8 was detected in higher percentage in plaque and nodule stage rather than patch stage with p=0.035. HHV 2 was detected in lesser percentage in lesion of hand and trunk rather than other sites with p=0.042. There was no significant difference in HHV8 positivity between the presence of HHV8 and age, gender and history of immunosuppression. Conclusion: Immunohistochemical detection of LANA HHV-8 is helpful in diagnosis of suspicious cases of KS, specially in lesion of plaque and nodule stage that are not located only in hand or trunk.

Background and Objectives: The aim of the study was to determine the role and characteristics of nosocomial and community acquired Staphylococcus sepsis in admitted children in tertiary centers in Iran. Patients and Methods: A cross sectional descriptive-analytic study was performed since March 2008 to March 2009 in which all blood cultures from various admitted patients were checked for Staphylococcu aurues in Aliasghar Children Hospital, Tehran, Iran. Upon diagnosis by appropriate microbiologic tests, antimicrobial testing was done according to CLSI methods. Results: Overall, 2647 blood culture samples from 5197 admitted children were sent from which, 25 cases of S. aurues septicemia were isolated; the rate was 4.8 in 1000 admissions;1.3 in 1000 admissions were nosocomial and 3.5 in 1000 admissions were community acquired sepsis. Ten cases were neonates and remainder was older. Eighteen cases were CA and 28% were NI septicemia with mean age of 38.8 months and 8.2 months, respectively. Mean duration of admission in NI group was 20.5 days, however it was 12.6 days in CA group; they also had higher mortality rate. Conclusion: The rate of Staphylococcus sepsis in this study was higher than developed countries for both CA and NI cases, both groups had high rate of resistance. Although most cases were CA in which significant proportion had underlying malignancy, NI group had a longer duration of admission and mortality.

Background and Objectives: Adenoid cystic carcinoma (ACC), the most common malignant tumor of submandibular and minor salivary glands, is characterized by a high rate of local recurrence and distant hematogenous metastasis and tendency to invade peripheral nerves. In spite of radiotherapy and surgical treatment, the long-term prognosis is dismal. Today, many studies are being conducted using the immunohistochemical markers to help in the evaluation of ACC prognosis. The present investigation was performed to survey immunohistochemically HER2/neu over expression in adenoid cystic carcinoma of salivary glands. Materials and Methods: The 24 existing samples of formalin-fixed paraffin embedded specimen were stained with HER2/neu markers. Tumors with moderate (2+) to strong (3+) complete membrane staining in at least 10% of the tumor cells were scored as positive for over expression. Results: The overall frequency of over expression for HER2/neu was 45.8% and 11 specimen were positive for HER2/neu expression. A significant relationship was found between HER2/neu over expression and grade of ACC. No significant relationship was detected between immunostaining of HER2/neu and histologic pattern. Conclusion: HER2/neu immunostaining might be reliable and useful for evaluation of ACC prognosis.

Human hydatid cyst is a wide spread disease. It is an endemic disease in Iran. Hydatid cyst is extremely rare in the female reproductive organs. This is a case report of ovarian hydatid cyst in a 42-year-old woman. She presented with feeling of enlargement of abdomen and abdominal pain. On physical examination, a large mass in lower abdomen palpated. Ultrasonography reported a heterogeneous multicystic mass measuring 155×97 mm in hypo gastric area. The CT-scan with IV contrast reported a huge cystic lesion, containing multiple septi that could be due to ovarian lesion. After surgery, histopathological examination showed typical laminated &germinative layers with hexagonal scolecies of hydatid cyst. Since the common sites of hydatid cyst are liver, lung, etc and the imaging studies are highly diagnostic for hydatid cysts; this illustrated case is interesting for uncommon site, not suggested by imaging studies and with clinical (surgical) impression of malignant ovarian tumor.

Primary non-Hodgkin lymphoma of liver is a very rare malignancy. Here we report a case of primary hepatic Burkitt’s lymphoma in a 34-year old man who was known case of acquired immunodeficiency syndrome (AIDS) and presented with weight loss, abdominal pain, and fever. Positive laboratory findings were mild anemia and elevated levels of lactate dehydrogenase (LDH) and alkaline phosphatase (ALP).Abdominal computed tomography (CT) showed multiple large low- density mass lesions in both lobes of liver with no evidence of regional or distant lymphadenopathy or metastasis. Liver needle biopsy was done and both histological and immunohistochemical findings were compatible with Burkitt’s lymphoma.
