Food-dependent exercise-induced anaphylaxis due to wheat in a young woman

Food Dependent Exercise-Induced Allergy is a rare condition. However, the occurrence of anaphylaxis is increasing especially in young people. The diagnosis of anaphylaxis is based on clinical criteria and can be supported by laboratory tests such as serum tryptase and positive skin test results for specific IgE to potential triggering allergens. Anaphylaxis prevention needs strict avoidance of confirmed relevant allergen. Food-exercise challenge test may be an acceptable method for diagnosis of Food Dependent Exercise-Induced Allergy and dietary elimination of food is recommended to manage it. In this study, a 32 year-old woman visited the allergy clinic with a history of several episodes of hives since 11 years ago and 3 life-threatening attacks of anaphylaxis during the previous 6 months. The onsets of majority of these attacks were due to physical activity after breakfast. On Blood RAST test, the panel of common food Allergens was used and she had positive test only to wheat flour. On skin prick tests for common food allergens she showed a 6 millimeter wheal with 14 mm flare to Wheat Extract. The rest of allergens were negative. The patient was diagnosed as wheat-dependent exercise-induced, and all foods containing wheat were omitted from her diet. In this report we emphasized on the importance of careful history taking in anaphylaxis diagnosis

Microbiology of Upper Respiratory Tract Pathogens in Cystic Fibrosis Patients

Cystic fibrosis (CF) is an inherited genetic disorder with chronic respiratory manifestations. The respiratory symptoms may start very early in life. The aim of this study was to evaluate the prevalence and antimicrobial susceptibility of respiratory pathogens in children with CF. In this clinical laboratory study, 100 CF patients were prospectively collected from February 2016 to March 2017. Microbiological cultures and antimicrobial susceptibility tests of the most frequently isolated upper respiratory tract bacteria were performed. According to the results of this study, Staphylococcus aureus was the most frequent microorganism 24 (24%) in CF patients followed by Pseudomonas aeruginosa 21 (21%). In children younger than one-year-old, Enterococci and Klebsiella pneumonia were the most frequently isolated pathogens. In other age groups, Staphylococcus aureus and Pseudomonas aeroginosa were most frequent. All pathogens showed more sensitivity to Ceftriaxone, Amikacin, and Ceftazidime. However, Staphylococcus aureus was most sensitive to Cefoxitin, Clindamycin, and Linezolid and Pseudomonas aeroginosa were most sensitive to Amikacin, Ceftazidime, and Ceftriaxone respectively. In conclusion, Staphylococcus aureus and Pseudomonas aeroginosa were the most frequent microorganisms in CF patients in our population. In patients younger than one-year-old, the most frequent pathogens were Enterococci and Klebsiella. All pathogens and Pseudomonas aeroginosa were sensitive to Ceftriaxone, Amikacin, and Ceftazidime but Staphylococcus aureus was most sensitive to Cefoxitin, Clindamycin, and Linezolid respectively. It seems that Ceftriaxone, Amikacin, and Ceftazidime are the most suitable antibiotics for the treatment of pulmonary infections in CF patients in our population

The Impact of Silymarin on the Symptom Severity in Pediatric Patients with Inflammatory Bowel Disease: A Randomized Clinical Trial

Background: Inflammatory Bowel Disease (IBD) is a multifactorial disease, posing significant challenges to public health. The aim of this study is to determine the effect of silymarin on the symptom severity in pediatric patients with IBD.Methods & Materials: This randomized clinical trial was conducted on children aged 5-18 diagnosed with IBD referred to the GI clinic at Akbar Children's Hospital in Mashhad. Those who met the inclusion criteria were randomly allocated into either the intervention or placebo group, each group consisting of 20 participants. In the intervention group, silymarin was administered three times daily in divided doses for three months. The control group received a placebo. To assess the efficacy of silymarin, PUCAI and PCDAI were evaluated for all patients at three different time points: before the intervention, during the first visit, and after the intervention. Data were analyzed utilizing the SPSS version 25, with a significance level set at p 0.05). However, a statistically significant difference was observed in the disease activity index score between the two groups during the second, and third evaluations (p<0.05)

Relationship between platelet count and platelet width distribution and serum uric acid 1 concentrations in patients with untreated essential hypertension

Hematological parameters have emerged as independent determinants of high serum concentrations of uric-acid and predictive-factors in the evaluation of the total cardiovascular-risk in patients with essential-hypertensive. Here we have investigated the possible relationships between hematological-factors and serum uric-acid levels in hypertensive-patients recruited as part of Mashhad-Stroke and Heart-Atherosclerotic-Disorders cohort study. Two-thousand three-hundred and thirty four hypertensive individuals were recruited from this cohort and these were divided into two groups; those with either high or low serum uric acid concentrations. Demographic, biochemical and hematological characteristics of population were evaluated in all the subjects. Logistic-regression-analysis was performed to determine the association of hematological-parameters with hypertension. Of the 2334 hypertensive-subjects, 290 cases had low uric-acid, and 2044 had high serum uric acid concentrations. Compared with the low uric acid group, the patients with high serum uric acid, had higher values for several hematological parameters, whilst platelet counts (PLT) were lower. Multiple linear regression analysis showed that PLT and serum hs-CRP were correlated with serum uric acid level. Stepwise multiple logistic regression model confirmed that PDW and gender were independent determinant of a high serum uric acid. PDW and PLT appear to be independently associated with serum uric acid level in patients with hypertension

Application of Permutation Genetic Algorithm for Sequential Model Building–Model Validation Design of Experiments

YesThe work presented in this paper is motivated by a complex multivariate engineering problem associated with engine mapping experiments, which require efficient Design of Experiment (DoE) strategies to minimise expensive testing. The paper describes the development and evaluation of a Permutation Genetic Algorithm (PermGA) to support an exploration-based sequential DoE strategy for complex real-life engineering problems. A known PermGA was implemented to generate uniform OLH DoEs, and substantially extended to support generation of Model Building–Model Validation (MB-MV) sequences, by generating optimal infill sets of test points as OLH DoEs, that preserve good space filling and projection properties for the merged MB + MV test plan. The algorithm was further extended to address issues with non-orthogonal design spaces, which is a common problem in engineering applications. The effectiveness of the PermGA algorithm for the MB-MV OLH DoE sequence was evaluated through a theoretical benchmark problem based on the Six-Hump-Camel-Back (SHCB) function, as well as the Gasoline Direct Injection (GDI) engine steady state engine mapping problem that motivated this research. The case studies show that the algorithm is effective at delivering quasi-orthogonal space-filling DoEs with good properties even after several MB-MV iterations, while the improvement in model adequacy and accuracy can be monitored by the engineering analyst. The practical importance of this work, demonstrated through the engine case study, also is that significant reduction in the effort and cost of testing can be achieved.The research work presented in this paper was funded by the UK Technology Strategy Board (TSB) through the Carbon Reduction through Engine Optimization (CREO) project

A New Era of the Fresh Start

The Journal of Reviews in Clinical Medicine (RCM) is the leading journal of its type at Mashhad University of Medical Sciences covering all aspects of the natural and clinical sciences, which may be a matter of concern for the related specialists. The scope of the journal defines the RCM Publishing Group's ambition to take a considerable step forward in constructing a valuable medical resource for both authors and readers. It offers the practical and the professional support for clinicians to spread the critical and constructive analysis in a specific field through extended explanations on the topic. In other words, it pragmatically provides the readers with recent advances and discoveries by means of previously published literature or data. Furthermore, the journal expects to generate the ideas of where the researches might go in the future. The RCM Publishing Group hopes to be a gateway to the positive outlook of research in any medical discipline. In this issue, we present the wide range of researches in different fields of medicine, which describe briefly below. Acute lymphoblastic leukemia (ALL) is one of the most common pediatric disorders that affected the large number of patients. Along with the high rate of treatment success, a modified and individualized diagnostic test can significantly increase the survival rate. Therefore, cytogenetic and molecular tests might play an important role in the prognosis of ALL by detecting the special genetic polymorphism affecting drug metabolism and its subsequent effective level and toxicity. Differential diagnosis between benign and malignant brain tumors has been a dilemma for appropriate management and treatment for years. Magnetic resonance spectroscopy is now addressing the need for noninvasive methods of measuring human brain function. Chronic kidney diseases such as renal failure are considered as the devastating medical problems in different age group. The long-term appropriate medical care especially nutritional support can exert a positive effect on patients` health. Furthermore, the use of tranexamic acid in cardiac surgery and its complications such as bleeding, the use of herbal medicine in the treatment of refractive seizure in children, the different causes of coma in pediatric medicine and also peripheral nervous system destruction occurred in systemic vasculitis has been discussed. Finally, we focus on cyclooxygenase 2 (COX2) as a major overexpressing enzyme in cancers. Thus, clinicians may consider COX 2 inhibitors as one of the therapeutic agents.  The previous studies evaluated this role are reviewed in Wilms` tumor. Above all, we want to express our appreciation to all those who have submitted their manuscripts to RCM journal, all the Editorial board members and all the dedicated staffs for their loyal and precious cooperation. We look forward to attracting more specialists, residents and medical students to make RCM a really international and multicultural journal. Frankly, this has promised to be a far more difficult task than we anticipated. However, we will continue our efforts to take the first steps in this evolution more effectively

Lessons learnt from basin management in Iran and the world (case study Helmand, Danube and Colorado basins)

In recent years, river flow into Sistan dam changed because of construction of dams and expansion of irrigation areas in the upper Helmand basin. Planning for construction of more dams and heightening of Kajaki dam in Helmand basin shall intensify the severity of water shortage of Sistan dam and Hamun Lake. Sistan dam located at downstream of Helmand river on Sistan branch of the Helmand river, power shifts in Afghanistan and expansion of irrigation areas in upstream basins and absence of an integrated authority/management in the basin are the major problems. Political nature of international protocols for management of the basin is another problem for water resource management in the region. Above mentioned issues forced the local water authorities to solve the problems using natural and man-made reservoirs and interlink canals, called Chah-Nimeh dams. This study focused on comparison of Helmand, Danube and Colorado river basins to find possible acts in Helmand basin
