Abstract
Background: Helicobacter pylori (H. pylori) cause various diseases especially gastrointestinal disorders. Clinical diagnosis of H. pylori infection can be done in different ways, and new diagnostic methods are under study .This study aimed to assess the levels of interleukin (IL) 6, 17 and 23 in the middle ear effusion of patients with otitis media, and the association between these levels with H. pylori infection.
Methods: This cross-sectional study conducted in 40 patients who nominated for ventilation tube (VT) placement due to otitis media with effusion, and admitted to ear, nose, and throat (ENT) clinics of Tehran University of Medical Sciences from March 2012 to August 2013. All of patients underwent myringotomy with VT insertion, and then aspirated effusion sample was tested. H. pylori infection diagnosed by polymerase chain reaction (PCR) and bacterial culture. The concentration of IL-6, IL-17 and IL-23 measured by enzyme-linked immunosorbent assay (ELISA). The levels of each interleukins were compared between the two positive and negative PCR groups.
Results: In all of samples, PCR test result was positive in 22.5%. The mean and standard deviation of IL-6 level was 10.11±2.95, IL-17 was 5.89±0.91 and IL-23 was 4.07±1.34. The mean±standard deviation (SD) of IL-6 level in patients with a positive PCR (H. pylori) was 22.29±6.40 and in patients with a negative PCR was 6.16±3.88 that difference was significant (P=0.01). The mean±SD of IL-17 level in patients with a positive PCR was 6.16±1.29 and in patients with a negative PCR was 5.81±1.13 that difference was not significant (P=0.42). The mean±SD of IL-23 level in patients with a positive PCR was 6.15±3.77 and in patients with a negative PCR was 3.42±1.33 that difference was not significant (P=0.27).
Conclusion: According to finding, association between H. pylori infection and increased levels of IL-6 in the middle ear effusion was approved. It is recommended to conduct researches aimed to identify other cytokines as inflammatory markers.

Abstract
Background: According to the direct connection between congenital hypothyroidism and iodine deficiency in pregnant women, also relatively high incidence of congenital hypothyroidism in some areas of Kerman province, especially Raver district located in North of Kerman province, this study was performed to determine and compare the urinary iodine concentration (UIC) in pregnant women referring to health centers.
Methods: This cross-sectional study was done during March 2014 and May 2015. Inclusion and exclusion criteria to be considered and UIC were measured by spectrophotometry in 384 and 374 pregnant women in Ravar and Kerman cities, Iran. Sampling method for this study was all of pregnant women in Ravar and random stratified sampling in Kerman. data were collected using a structured questionnaire. All statistical analyses were performed using SPSS Software, version 20.0 (IBM SPSS, Armonk, NY, USA). Chi-square test, Pearson's correlation coefficient and Logistic regression were used for associations and differences.
Results: The mean UIC was 200.21 µg/L in pregnant women of Ravar and 238.79 µg/L in pregnant women of Kerman. 22.7% of pregnant women were with low concentrations of iodine, 57.8% within the normal range and 19.5 percent were with high iodine concentrations in Ravar. While 5.3 percent of pregnant women were with low concentrations of iodine, 54.5% were within the normal range and 40.1% were with high UIC in Kerman. There were no significant differences between demographic variables and UIC in the two regions (P> 05/0). Multivariate regression models showed significant connections between the residence and UIC pregnant women (P< 0.001).
Conclusion: The results of this study showed that UIC in pregnant women of Ravar was significantly lower than Kerman and the place of living can be considered as a predictor of UIC in pregnant women.

Abstract
Background: Decompressive craniectomy (DC) is a therapeutic approach for patients with raised intracranial pressure and cerebral edema. Although DC is not a complicated procedure, it is associated with significant complications and morbidities that significantly affect clinical outcomes. This study investigates the frequency of cerebrospinal fluid (CSF) circulation disorders after DC and evaluates related factors.
Methods: This cross-sectional analytical study was conducted on 79 patients who underwent DC at Shohadaye Haftome Tir Hospital, one of the main trauma centers in Tehran. The patients' files and the Picture Archiving and Communication System (PACS) were reviewed to collect demographic, clinical, and radiologic data. After identifying patients with post-operative (after DC) CSF circulation disorders, the relevant factors were determined using multivariate logistic regression.
|
Results: Overall, seventy-nine patients were studied. The mean age of patients was 40.56±12.64 years and 82.3% were male. Forty-seven patients (59.5%) underwent DC due to traumatic causes and thirty-two patients (40.5%) due to vascular pathologies. In total, 36.7% (nineteen) of patients were affected by some degree of subdural hygromas of which 13 patients (44.8%) progressed to clinical and radiologic hydrocephalus. 19% (fifteen patients) developed hydrocephalus within the first six months after surgery. Considering the clinical variables, the GCS of patients was the only one that showed a significant relationship with CSF circulation disorders. Regarding radiological variables, the presence of intraventricular hemorrhage (IVH) was the only relevant factor. In addition, from the surgical perspective, performing duraplasty (autograft or allograft) and reoperation demonstrated significant relationships with CSF circulation disorders. The results of multivariate logistic regression showed that having intraventricular hemorrhage (OR, 6.15-6.9414: CI95%, P=0.003) and reoperation (75.91: OR, 3.88-3.6, 1485/43: CI95%, P=0.004) were two independent factors associated with hydrocephalus in DC patients.
|
Conclusion: In patients who have undergone decompressive craniectomy, intraventricular hemorrhage (IVH) and reoperation can be independent risk factors for CSF circulation disorders. Although the incidence and presence of IVH cannot be controlled, careful and meticulous surgical technique and skill can significantly improve the outcome of decompressive craniectomy by reducing the need for reoperation
