Abstract Background and objectives: Paranasal sinuses are the common place for infection in children and adults. Early and effective antibiotic treatment is necessary to reduce the infection period and mucosal injuries, and to prevent from the Involvements of orbit or CNS. This article aims to clarify the Serum immunoglobulins accompanying by Sinusitis in Children. Material and Methods: the Subjects of this Cross-Sectional study were 400 patients with paranasal sinusitis confirmed by imaging techniques. The study was conducted in infectious and ENT Clinics of Rasoul Akram hospital in 2003-2004. We measured the Levels of serum immoglobulins including IgG, IgM, IgA and IgE by standard radio-immunodiffusion test, and Compared with normal range of each age group. The data was analyzed by SPSS software (11.5) Results: The Subjects aged 4.42±2.62 are both male (70.7%) and female (29.3%). Maxilla is the most Common Sinus involved. Thirty-eight of them (95%) have increased IgG Level. Forty-four percent of children suffered from rhinosinusitis have been diagnosed with Immune-humoral disorders: the increase of IgE (N=9), Lack of IgA (N=3), decrease of Isolated IgG (N=2), decrease of both IgG and IgA (N=1) and Hyper IgM syndrome (N=3). There is Significant Correlation between different Immunoglobulins and duration of Sinusitis (P<0.05). Conclusion: The results of this study show that an increase of IgE is one of the most Common disorders in children suffering from Sinusitis and the incidence of immunity disorders is higher than the expected rate. Thus, we recommend the Immunologic assessment for Children Contracting with Sinusitis, esp. for protracted one. Key words: Rhinosinusitis, Hypogamma Globulinemia, Resistant Rhinosinusitis, Serum Immunoglobulins

Abstract Background and objectives: cardiac surgery is often associated with acute kidney injury (AKI). Nowadays, AKI is typically diagnosed by an increase in serum creatinine, which is a delayed and unreliable biomarker. Recent studies recommended using the liver type fatty acid binding protein (L-FABP) as an early biomarker. Material and Methods: The urine samples of 18 adult patients undergoing cardiac surgery were collected in different times before (2, 4,8,24 hour) and after cardiac surgery for detection of L-FABP by Elisa. Results: The results from ELISA test show that the increasing amount of L-FABP in urine samples of 4 patients is a diagnostic indicator for AKI. The mean concentration of L-FABP has increased up to 17 times at 8 hours after cardiac surgery compared to before surgery. Conclusion: according to our findings, we speculated that the urinary L-FABP can be a reliable and rapid biomarker for diagnosis of acute kidney injury. Key words: Acute Kidney Injury, Liver type Fatty Acid Binding Protein, Cardiac surgery

Background and objectives: The hoteling quality promotion is part of the health system development plan, based on which the physical appearance of laboratories of public hospitals are improved and renovated. The present study aimed to evaluate the policy-making gap in the hoteling quality promotion of the health system development plan in providing laboratory services in public hospitals in the Golestan Province, Iran.
Methods: This descriptive-analytical and cross-sectional study was performed on 384 medical staff and physicians working in laboratories of public hospitals affiliated with the Golestan University of Medical Sciences, Golestan Province, Iran. Data were collected using a 35-item researcher-made questionnaire that was distributed and collected over a period of six months. We examined the extent of the gap between the current and expected status based on the two components: the alignment of key stakeholders with health system development policies and stakeholders' opposition to health system development policies, as well as the extent of the gap
Results: The hoteling quality promotion was about -0.05 in providing laboratory services in public hospitals of the Golestan Province, indicating a low gap between the current and favorable status in the fifth axis of the health system development plan in terms of supervision.
Conclusion: The implementation of the hoteling quality promotion plan in providing laboratory services in public hospitals of the province is not consistent with the expected goals of the fifth axis of the health system development plan. Therefore, there is a need to examine and eliminate effective factors contributing to this gap.

Background: Improving the quality of visit services in laboratories of medical-teaching centers of universities of medical sciences plays a major role in providing better services to patients. The present study aimed to evaluate the policy of improving the quality of visit services of the reform plan in laboratories of medical-teaching centers in Golestan province.
Methods: The present research was cross-sectional and had a descriptive-analytical type. A total of 384 staff in the diagnostic laboratories were selected for the study using a simple random sampling method. The data collection tool included a 35-item researcher-made questionnaire.
Results: There was a gap between the current and desired status of the fourth axis of the health system reform plan. The gap was about -0.01, indicating that there was a gap between the current and desired status and it was related to the supervision department according to the respondents in the target statistical population.
Conclusion: The implementation of this plan was effective in improving the quality of visit services in laboratories of medical-teaching centers in Golestan province but this effectiveness did not meet the goals of the fourth axis of the reform plan. Therefore, the factors, which caused a lack of supervision among the executive departments of laboratories of medical-teaching centers in Golestan province, should be removed for increasing the effectiveness of this plan.
