ABSTRACT
Various allergens are implicated in the pathogenesis of allergic diseases in different regions. This study attempted to identify the most common allergens among patients with allergies based on the results of skin prick tests in different parts of Iran. Relevant studies conducted from 2000 to 2016 were identified from the MEDLINE database. Six common groups of allergen types, including animal, cockroach, food, fungus, house dust mite, and pollen were considered. Subgroup analysis was performed to determine the prevalence of each type of allergen. The Egger test was used to assess publication bias. We included 44 studies in this meta-analysis. The overall prevalence of positive skin test results for at least one allergen was estimated to be 59% in patients with allergies in various parts of Iran. The number of patients was 11,646 (56% male and 44% female), with a mean age of 17.46±11.12 years. The most common allergen sources were pollen (47.0%), mites (35.2%), and food (15.3%). The prevalence of sensitization to food and cockroach allergens among children was greater than among adults. Pollen is the most common allergen sensitization in cities of Iran with a warm and dry climate; however, sensitization to house dust mites is predominant in northern and southern coastal areas of Iran.

OBJECTIVE@#To evaluate the effect of doxorubicin and its pegylated liposomal formulation (Doxil, Caelyx) on in vitro susceptibility of promastigote and amastigote stages of Leishmania major.@*METHODS@#Throughout in vitro assays the IC was calculated in the promastigotes and amastigotes forms in J774 macrophage cell line. Also as cytotoxicity in J774 cell line macrophages.@*RESULTS@#Doxorubicin and Doxil showed the same activity against promastigote form with IC values of 10.49 μg/mL and 9.63 μg/mL, respectively. Similarly, the amastigote stage was susceptible at concentration of at least 1 μg/mL when compared to positive control (P < 0.0001). Also, cytotoxicity assay against macrophage revealed no toxicity on the host cells at IC concentrations.@*CONCLUSIONS@#Our findings demonstrated the efficacy of both doxorubicin and its pegylated liposomal formulation on L. major at low concentrations. Further researches are needed for evaluating the safety of drugs in animal model particularly as topical formulation.
ABSTRACT
OBJECTIVE@#To evaluate the overall prevalence of Toxoplasma gondii infection among birds and poultries in Iran.@*METHODS@#Data were systematically collected from 1983 to 2016 in Iran on the following electronic databases: PubMed, Google Scholar, Science Direct, Scopus, Web of Science, Magiran, Irandoc, IranMedex, and Scientific Information Database. Additionally, the abstracts of national scientific congresses and dissertations were included.@*RESULTS@#A total of 20 articles in the field of birds and poultries toxoplasmosis, totally examining 4563 cases with 754 positive results reporting the overall prevalence of infection from all parts of Iran could fulfill our eligibility criteria. The overall estimated prevalence included in chicken 20% (95% CI: 3%-38%) in chicken, pigeons 8% (95% CI: -17%-33%) and in sparrows 15% (95% CI: -25%-54%).@*CONCLUSION@#Although there is a lack in data about poultries and birds toxoplasmosis in Iran, our meta-analysis revealed that infection rate is high among birds and poultries in Iran. More studies are needed to manage controlling programs and prevention strategies among poultries in Iran.

ABSTRACT
To evaluate the effect of mode of delivery on postpartum sexual functioning in primiparous women. In this cross-sectional descriptive study, 150 primiparous women in postpartum period, who attended the family planning or vaccination clinics, were enrolled for the study. Eighty-one had vaginal delivery with episiotomy and 69 had experienced cesarean section. Sexual function was evaluated by the Female Sexual Function Index within 3 and 6 months postpartum. About 29% in vaginal delivery group and 37% in cesarean delivery group had resumed their sexual intercourses four weeks after delivery [p=0.280].There were no significant differences between mode of delivery and sexual functioning, including desire, arousal, lubrication, orgasm, satisfaction and pain. The present study showed that postpartum sexual functioning was not associated with the type of delivery
ABSTRACT
<p><b>OBJECTIVE</b>To determine the prevalence of intestinal parasitic infections among mentally retarded residents of rehabilitation center of Bandar Abbas, Hormozgan province, southern Iran.</p><p><b>METHODS</b>A cross-sectional study was carried out in central rehabilitation institute of Hormozgan province in summer 2010. Fecal samples of all 133 residents (72 males, 61 females) aged 3-52, were collected in triplicate. Specimens were examined by direct smear, formalin-ether concentration techniques and stained by permanent Trichrome, Ziehl-Neelsen stains. Statistical analysis was conducted by SPSS 13.5.</p><p><b>RESULTS</b>Intestinal parasitic infections were seen in 48.5% (64 out of 133 subjects: 53.4% in males and 46.6% in females). Strongyloides stercoralis with 17.3% showed the highest incidence followed by Entamoeba coli (9.8%), Blastocystis hominis (7.5%), Giardia lamblia (2.3%), Endolimax nana (2.3%), Hymenolepis nana (0.8%), Oxyuris vermicularis (0.8%), and Chilomasix mesnili (0.8%). Double infections were found to be as: Strongyloides stercoralis + Giardia lamblia (2.3%), Entamoeba coli + Giardia lamblia (1.5%), Entamoeba coli + Blastocystis hominis (1.5%), Oxyuris vermicularis + Entamoeba coli (0.8%), Strongyloides stercoralis + Entamoeba coli (0.8%), respectively.</p><p><b>CONCLUSIONS</b>Our findings reveal that strongyloidiasis is a common disease among mentally retarded population in southern Iran.</p>
