Recently, Metal Organic Frameworks (MOFs) have been widely applied due to their high energy storage capacitance, customizable pore sizes, and open metal sites; however, their application in the form of electrode materials has been restricted due to their poor electrical conductivity. The present study reports the fast synthesis of MIL-53(Fe) and Pd/MIL-53(Fe) using the solvothermal method. To assess the electrochemical potential of materials and better understand the role of palladium in the presence of MOF, the electrodes of materials were constructed and electrochemical performances of both samples were investigated based on cyclic voltammetry in 6 M KOH electrolyte. Due to the existence of Pd in redox reaction and larger surface area, the Pd/MIL-53(Fe) showed greater electrochemical efficiency  and higher specific capacitance than MIL-53(Fe). The obtained results also indicated that designing MOF via decoration of noble metal nanoparticle (MOF/noble metal) would find potential applications in the field of supercapacitors and catalysis.

Colistin resistant Acinetobacter baumannii strains have become an important treat in nosocomial infection control. The reliable detection of these strains plays a critical role in treatment procures. The aim of this study was to evaluate the three different methods in detection of colistin resistant A. baumannii strains. Eighty-three A. baumannii strains were isolated from hospitalized patients of a teaching hospital in Tehran during 1 year (2016-2017). All isolates were genetically confirmed by Polymerase Chain Reaction (PCR). The resistance to colistin was determined with disc diffusion, E-test, and micro broth dilution method. According to the results of micro broth dilution as a gold standard, 43% of the isolates were resistant to colistin, while this percentage was 23% and 44% through E-test and disc diffusion methods, respectively. The positive and negative predictive value (PPV and NPV) of this method was 43% and 57%, respectively. The sensitivity and NPV index of E-test for the detection of colistin resistant strains was 76% and 68%. Detection of colistin MIC by E-test strips has been commonly used in clinical laboratories to recognize the colistin susceptible strains. The NPV and sensitivity of E-test method demonstrated that this method has inefficacy to accurate determination of colistin susceptible strains. Thus, using standard protocol micro broth dilution with qualified materials should be stabilized and replaced instead of disc diffusion or even using E-test in clinical laboratories.

Given constipation as one of the common digestive problems in pediatric patients, the psychiatric comorbidities together with chronic constipation may result in some disorders in children’s life quality. This study aims to evaluate the life quality and psychiatric comorbidities in 2 to 18 years old children and teens with constipation.
Material & This study, as a case control study was conducted through many children and teens who were homogeneous in terms of sex and age, 55 patients with functional constipation and 55 people without it. The parents and children were provided with questionnaires of the demographic particulars, QOL and SQD, following collection of their history and physical examinations. The analysis of the collected data was done based on the statistical tests of Chi-Squared test, one sided variance analysis and T-test through SPSS 16 software.
The average scores of the life quality obtained from the children and parents were 54.67%.9 and 49.86%.2 in the case group and 63.26%.0 and 66.09%.4 in the control group, with a significant difference in the score reported by the parents (P=0.014). A difference has been observed between these two groups due to emotional performance (P=0.024 for parents and P=0.016 for children). The total estimated score of SDQ questionnaire employed for these two groups indicated abnormality of 93% in the case group and 83% in the control group which were statistically not significant (P=0.631). There was no difference through the subgroups mentioned in this questionnaire and the impact scores of these two groups (P>0.05).
The life quality based on the parents’ reports and the emotional performance in the children with constipation are too low; and screening through children is recommended to help them in the treatment and the control of the constipation and its severity by referring to the child psychiatrists.

acute upper respiratory infections (URI) are one of the most common infections in childhood. It is estimated children younger than 5, suffer from 4 to 8 episodes annually, andURI incidence is 2 million children all around the world. The aim of this review was to evaluate and summarized studies about relation between probiotic and upper respiratory tract infection in children. The articles were identified by searching the Cochrane Library, PUBMED, Scopus and MEDLINE, IranMedex, Google Scholar, Ovid, Science Direct, Margiran, Scientific Information Database up to December 2014. We selected key words regard to MeSH Database (probiotic AND respiratory infection AND children). Nine types of probiotics were used on 2261 children in these studies, included KB29, CRL-431, BB-12, TH-4, FOS, CRL431, DSM17938، Lactobacillus acidophilusand Bifidobacteriumbifidum. Only two studies reported the side effects of probiotics. these studies revealed that probiotic administration could reduce the duration of upper respiratory tract infection and decrease the loss of school days.

Neck mass is the most common complaints among patients referred to otolaryngology clinics and involve a wide range of differential diagnosis of localized disease, metastatic and systemic. In addition to the patient anxiety, it is also a diagnostic problem for medical staff. Matherials and At a Cross-sectional study in 2011 to 2013, after excluding 58 acute infective cases, 203 patients (110 males and 93 females) who have clinically neck mass or masses referred to the ENT clinic of Imam Reza Hospital, Mashhad were selected. The clinical and demographic variables in terms of location, quantity, consistency, cohesion, sensitivity and communication with other organs of the lesion, pathology and disease duration were evaluated. Some patients diagnosed during the study FNA and endoscopy and definite diagnosis of the lesion was determined based on the biopsy result. The most common pathology observed in men was: SCC (37/38 percent), sialoadenitis (11/21%) and Tyrvglvsal duct cyst (7/5%) respectively, and in women was: tuberculosis (18/89 percent), SCC (15/55%) and nodular goiter (7/8 percent) respectively. The possibility of neoplastic cervical mass in men was more than women. The neoplastic lesions rate showed an increase with age (P <0.05). After eliminating the causes of inflammatory, SCC is the most common disease in men and Tuberculosis in women that so often can be seen in the posterior triangle of the neck juglodigastric lymph chain.

Meningitis is one of the important emergencies in pediatrics. Proper and timely treatment prevents high mortality and morbidity of bacterial meningitis. Given that only5% of meningitis are bacterial، finding a sensitive method to discriminate between the two types of meningitis is of clinical importance. In this study procalcitonin levels as a criterion for the diagnosis of bacterial meningitis and aseptic was studied. This was a case control cross sectional study in which 32 children with clinically suspected meningitis admitted to the hospital were studied. According to the clinical findings and results of CSF analysis، the patients were classified into two groups: bacterial meningitis and aseptic meningitis. For all cases CSF analysis & culture were done and procalcitonin،ESR، CRP & WBC were measured. Twenty healthy children were selected as control group and their procalcitonin and WBC was measured. Data were analyzed by SPSS software. The average age was 42. 6 months. There was no significant difference between two groups in terms of age، sex، ESR، CRP and CSF culture. Serum procalcitonin levels in control group were less than 0. 5ng/ml. 80% of bacterial meningitis and only one child (8. 33%) in aseptic meningitis had serum procalcitonin more than 2ng/ml. Serum procalcitonin level could be used as a useful diagnostic test with the cut of point 0. 5ng/ml differentiating healthy subjects from patients with meningitis. and Procalcitonin more than 2 ng / ml can be identified as Cut of Point diagnosis of bacterial meningitis.

A 14 year old female complained of abdominal pain and distention with vomiting. The physical exam showed thyroid enlargement and ascites. The imaging evaluation demonstrated a large ovarian cyst. Laboratory tests depicted hypothyroidism and marked elevation of Carbohydrate antigen 125 (CA-125) levels. As the bone age was 10 years, more retarded than the chronological age, Van Wyk and Grumbach syndrome was suspected. Treatment with thyroid hormone was initiated and the condition improved dramatically with disappearance of symptoms and signs 5 weeks later.

Urinary tract infection (UTI) is a common and serious clinical problem in newborns. Previous studies have suggested that jaundice may be one of the signs of a UTI in infants. The aim of this study was to evaluate the incidence age presentation severity of jaundice signs and complications of UTI in newborns with asymptomatic unexplained indirect hyperbilirubinemia in the first month of life. This case-control study was conducted at the Neonatal intensive care unit Ghaem Hospital in Mashhad from May 2004 to April 2009. We evaluated asymptomatic jaundiced infants for the evidence of having UTI. Some laboratory tests such as a serum fractionated bilirubin level as well as urinanalysis and a urine culture were performed in all patients. Renal ultrasound was performed in almost all the cases with UTI. Detailed questionnaires which were included demographic information prenatal intrapartum postnatal events and risk factors were filled. The control group was jaundiced- infants with unknown etiology. A total of 1487 patients were enrolled in this study. From these patients 1061 infants were evaluated for UTI. There was a statistically significant difference (P
