In various parts of the world the prevalence of antibodies to CMV ranges from 40-100%. The prevalence of primary infection with CMV in pregnant Iranian women and risk of congenital CMV infection in their neonates are unknown. To Determine the prevalence of CMV infection in primiparous pregnant (youner) women and incidence rate of cangenital CMV infection among preterm and full-term infants borned from these women, in serum of 164 primigravid women before delivery, CMV IgG and IgM antibodies were measured by ELISA method and CMV-DNA detection by PCR in ~10% of their infants. 100% of women were immune to CMV infection (CMV-IgG positive) were detected in mothers and newborns. Therefore, we can not compare gestational age and weight of infants in seropositive and serongegative mothers. Probably, in Iranian pregnant women, CMV screening test is not recommended. https://acta.tums.ac.ir/index.php/acta/article/view/2597 https://acta.tums.ac.ir/index.php/acta/article/download/2597/2579

This technique avoids a cutaneous scar and causes less surgical trauma and bleeding than that seen in conventional lacrimal surgery. A total of 20 endoscopic laser-assisted dacryocystorhinostomy in 16 patients were performed between 1998 and 1999. the procedure was successful in 90% of cases, with no major complications. This success rate is comparable with external dacryocystorhinostomy. Silicone tubing was applied in 11 cases. The difference of success rates between the two groups (with and without silicone tubing) was not significant. It seems that creading a patent rhinostomy plays a more important role to achieve desirable results. Endonasal endoscopic laser-assisted dacryocystor-hinostomy provides a simple, bloodless, and incisionless alternative to external dacryocytorhinostomy in the majority of the patients suffering from symptoms of lacrimal obstruction. https://acta.tums.ac.ir/index.php/acta/article/view/2598 https://acta.tums.ac.ir/index.php/acta/article/download/2598/2580

Not only differentiation of these two spectra but also the problems to achieve early diagnosis and treatment, have been a matter of concern, research, and controversy. Two hundred patients were assessed at the Cancer institute of Imam Khomeini Hospital as a retrospective research, considering the aim of evaluating and comparing the results of ultrasound and fine needle aspiration cytology with the postoperative histopathologic report. The ultrosound findings included location, number, size, feature, echogenicity, and presence of calcification; and those of the fine needle aspiration cytology consisted of benign, malignant, and suspicious samples. The cases mentioned as recurrent cancer or metastases of previous thyroid cancer were omitted from the study. In this research we found a sensitivity, specificity, accuracy of 92.3% , 76.4% and 88.1%, respectively , for fine needle aspiration cytology and also showed that the sensitivity and accuracy of fine needle aspiration cytology in diagnosis of malignant lesions of solid nodules was more than in cystic or mixed nodules of thyroid. Moreover, the incidence of false negatives in malignant cases of the studied sample was 7.7% (11/43). This rate was very higher in mixed and cystic lesions compared to benign ones (20% versus 5.7%). According to ultrasound findings, we showed that micro-calcificantion had a significant higher frequency in malignant nodules in comparision with the benign ones (4% in benign lesions versus 35% in malignant ones).

Thirty saline-treated (normal group) and thirty doxorubicin treated rabbits (1 mg/kg administered intravenously twice weekly for 8 weeks) were studied after 16 weeks of treatment. Chronic heart failure was confirmed by histopathology. Arteries and veins were cut as rings and so bathed in Krebs maintained at 37°C and gassed with 95% O2 and 5% CO2. Then all tissues were placed under different resting tensions and allowed to equilibrate for 1 hour. Then all the tissues were contracted with U-46619 (0.1 µM) nearly ten minutes before initial applications of isoprenaline. When the U-46619 (0.1 µM). induced contraction reached a plateau, concentration-response curves to isoprenaline were obtained. Isoprenaline was chosen as vasodilator resulting from stimulating beta-receptors in blood vessels. Maximum effect (Ema) and median effective concentration (EC50) were determined from each concentration-response curve and pD2 was calculatd as-log (EC50). Isoprenaline induced relaxations in all vessels. Aorta and renal artery were the most sensitive ones and had the maximum relaxations (15-20%). In relaxation due to β-adrencoeptor agonist isoproterenaol, the aorta and renal artery were the most sensitive vessels. Compared with control, in doxorubicin treated rabbits, Emax of isoprenalin was not modified in all the studied vessles. Relaxation responses were negligible and maximum responses in vena cava, and renal vein were only-5-10 percent. Of all vessels there was no significant difference between control and doxorubicin induced of heart failure in response to isoprenaline. https://acta.tums.ac.ir/index.php/acta/article/view/2601 https://acta.tums.ac.ir/index.php/acta/article/download/2601/2583

Patients’ medical records reviewed anda retrospective diagnosis was reached according to DSM-IV for Alzheimer’s disease (AD) and NINDS-AINS for vascular dementia (VaD). Mann-Whitney, fisher’s exact test, bivariat regression were used for analysis.Clinical features of majority of patients were complicated with mental symptoms. Subcortical lesions were observed in both dementias but it was significantly more frequent in the VaD (P=0.000). No significant differences in the number of patients with cortical atrophy between two groups was observed. Significant agreement between SPECT and retrospective clinical diagnosis was observed (kappa=0.18, P=0.02), but no significant pattern of hypoperfusion which could predict the clinical diagnosis was observed.This study emphasis on clinical diagnosis and the clarity of the referral process for doing neuroimaging evaluation. More sophisticated studies, either structural of functional such as volumetric measurement of medial temporal lobe, could be helpful to confirm clinicians in their diagnosis of patients with dementia. https://acta.tums.ac.ir/index.php/acta/article/view/2602 https://acta.tums.ac.ir/index.php/acta/article/download/2602/2584

To determine the frequency of primary immunodeficiencies (PID) in Iran, the Iranian primary Immunodeficiencies Registry (IPIDR) was organized in 1999. the diagnosis of immunodeficiency in our patients was based on standard criteria. The patient’s data were extracted, by using a uniform questionnaire from their hospital records. Three hundred and twenty eight patients with PID have been registered in our registry till 2000. Among these patients, the following frequencies were found: predominantly antibody deficiency in 48.48% of patients (n=159), T-cell disorders in 25.91% (n=85), phagocytic disorders in 24.7% (n=81), and complement deficiencies in 0.91% (n=3). Common variable immunodeficiency was the most frequent disorder (n=73), followe by chronic granulomatous disease (n=55), ataxia telangiectasia (n=39), x-linked agammaglobulinemia (n=35), selective IgA deficiency (n=34).

With immuno-histochemical methods using monoclonal and polyclonal antibodies we showed that B1 integrins were expressed in rat joint cartilage. Joint cartilage lesions were detected in ofloxacin-treated and magnesium-deficient rats. Lesions were more pronounced in the quinolone-treated group. Expression of several integrins was reduced in the vicinity of lesions after oral treatment with 2×600 mg ofloxacin/kg body wt for one day. Gross-structural lesions (e.g. cleft formation, unmasked collagen fibres) in magnesium deficient rats were very similar but changes in intergrin expression were less pronounced. Alterations observed on the ultrastructural level showed striking similarities in magnesium-deficient rats and in rats treated with single doses of 600 mg ofloxacin per kg body wt.Typical observation were: bundle shaped, electron-dense aggregates on the surface and in the cytoplasm of chondrocytes, detachement of the cell membrance from the matrix and necrotic chondrocytes, reduced synthesis and/or reduced of extracellular matrix and swelling of cell organelles such as mitochondria.The results of this study confirm our previously reported finding that quinolone-induced arthropathy probably is caued by a reduction of functionally available magnesium (ionized Mg2+) in cartilage. Furthermore, they provide a basis for aimed studies with human cartilage samples from quinolone-treated patients which might be available postmortal or after hip replacement surgery https://acta.tums.ac.ir/index.php/acta/article/view/2604 https://acta.tums.ac.ir/index.php/acta/article/download/2604/2586

Each infant received a 2.5% povidone iodine solution, or 0.5% erythromycin ointment or no prophylaxis as a control group. There were 17.5% , 10% and 5.8% of infectious conjunctivitis in control, erthromycin and povidone iodine groups respectively. In spite of reduction of clinical and infectious conjunctivitis in erythromycin compared to control group and in povidone iodine compared to erythromycin group, the only and most significant difference was between povidone iodine and control groups (P=0.0036 for clinical conjunctivitis and P=0.0089 for infectious ones). The most common organisms were gram-negative bacilli and staphylococcus aureus in all groups and chlamydia trachomatis was responsible for 9.5% of infectious conjunctivitis (4 th common agent) with an incidence of 1.7% in control group. As well, birth in unhygienic environment (mother defecation) and meconium staining of amniotic fluid were significantly associated with higher conjunctivitis rate but vaginal infection of mother had no such effect.
