Hypercalciuria in children with urinary tract symptoms
Fallahzadeh M,Fallahzadeh M,Mowla A,Derakhshan A
Saudi Journal of Kidney Diseases and Transplantation , 2010,
Abstract: We performed this prospective study to determine the urinary calcium to creatinine ratio (Ca/Cr) in children with different urinary symptoms. We studied 523 children in our neph-rology clinic with an age range of 3 to 14 years (mean= 8) and male to female ratio of 0.61. All the children had at least one of the urinary tract symptoms (dysuria, frequency, urgency, abdo-minal and/or flank pain, diurnal incontinence or enuresis), microscopic hematuria, urinary tract infection or urolithiasis. Fasting urine was collected for measuring calcium and creatinine and the results were compared to the values for the normal Iranian children. Ca/Cr ratio of more than 0.2 (mg/mg) was considered as hypercalciuria. Of all the patients, 166 (31.3%) were hypercalciuric. Urine Ca/Cr ratio was significantly higher in all the subgroups with one or more of the urinary symptoms (P< 0.001). We conclude that urine Ca/Cr ratio is significantly increased in children with all types of urinary symptoms. We recommend measuring urinary calcium in all children with urinary tract symptoms, especially if unexplained.

Insecta, Hymenoptera, Chalcidoidea, Eurytomidae and Torymidae in Iran
Fallahzadeh, M.,Narendran, T. C.,Saghaei, N.
Check List , 2009,
Abstract: A taxonomic checklist of 43 species of Eurytomidae belonging to seven genera, and 41 species ofTorymidae belonging to 15 genera, are currently recognized as occurring in Iran. Based mostly on various faunisticsurvey reports; no eurytomid or torymid species with collection records from Iran have previously been listed.Therefore; we did not intend to confirm identifications of previous studies, except in very obvious cases. A morecomprehensive collection-based study is needed to confirm the actual Iranian occurrence of each species listed in thischecklist.
Comparison of Growth Parameters in Five Year-Old Children with and Without History of Low Birth Weight
M Karimi,R Fallah,M Fallahzadeh,A Dehghanpoor
Journal of Shahid Sadoughi University of Medical Sciences , 2012,
Abstract: Introduction: Nowadays Low birth weight(LBW or birth weight<2500g) is one of the most serious problems among children around the world. The purpose of this study was to evaluate and compare the growth parameters(weight, height, head circumference and BMI) of LBW children at the age of five years with normal birth weight (NBW: birth weight: 2500- 4000 g) children. Methods: In a cross-sectional analytic study, growth parameters of five year-old children referred to Azadshahr health care center in Yazd, Iran, from December 2008 to June 2009 were evaluated. NBW and LBW children were selected as control and case groups, respectively. Results: Means of all growth parameters were significantly lower in LBW group. Frequency of severe failure to thrive and short stature was significantly higher in LBW group. Frequency of underweight was higher in LBW group and frequency of obesity was higher in NBW one. Frequency of underweight was higher in LBW girls. Conclusion: Considering that growth in LBW children is slower than NBW children in the first five years of life, it is necessary to emphasize the importance of growth assessment of LBW children for early and timely diagnosis, work-up and management of growth retardation and prevention of subsequent problems.
Solution of two-dimensional Fredholm integral equation via RBF-triangular method
Amir Fallahzadeh
Journal of Interpolation and Approximation in Scientific Computing , 2012, DOI: 10.5899/2012/jiasc-00002
Abstract: In this paper, a new method is introduced to solve a two-dimensional Fredholm integral equation. The method is based on the approximation by Gaussian radial basis functions and triangular nodes and weights. Also, a new quadrature is introduced to approximate the two dimensional integrals which is called the triangular method. The results of the example illustrate the accuracy of the proposed method increases.

Iranian Journal of Pediatrics , 2007,
Abstract: Objective: In medicine, especially in the field of pediatrics, it is necessary to perform regular epidemiologic studies in each geographic region. We designed this study in Nemazee Hospital, Shiraz (the major referral pediatric center in Southern Iran), to determine the disease spectrum, the mortality and also the rate of matching final diagnosis with the initial impression in pediatric wards.Material & Methods: All children older than 1 month (2731) who were admitted in Nemazee Hospital (except for surgical wards), from November 2005 to October 2006, were studied through questionnaire interviewing on admission and were followed till discharge or expire time. In some instances that final diagnosis or cause of death was unclear; we followed them through their files in clinics up to 1 year.Findings: Among 3057 admissions (related to 2731 patients), 56.8% were males (male to female ratio: 1.31). Patients age was 31 days to 25 years (mean: 5.16 years, SD: 4.98 years) and the significant portion was less than 2 years (1270= 44.2%). Admission duration varied from 1 to 62 days (mean: 5 days, SD: 5.13 days). The most common diseases were seizure disorder (315=11.1%), pneumonia (235=7.7%), febrile convulsion (136=4.79%) and gastroenteritis (128=4.18%). 17.93% of admissions came out of Fars Province (18 Provinces) with digestive system (19.1%), infectious (18.5%) and nervous system diseases (15.0%) as the most frequent referred patients. In 90.6% of admissions final diagnosis was clarified in the hospital (ranged from 86.45% in infectious ward to 93.4% in cardiology ward) (P=0.01). The total mortality rate was 5.30%; this rate was 9.49% for patients younger than 1 year and 5.0% in older patients (P<0.001). Conclusion: The most common age of admission in pediatric wards was less than one year. The most common diseases were seizure disorder, pneumonia and gastroenteritis. Congenital heart disease, sepsis and pneumonia were the most common diseases leading to death.
A Compact Microstrip Bandstop Filter
Saeed Fallahzadeh;Majid Tayarani
PIER Letters , 2009, DOI: 10.2528/PIERL09082407
Abstract: In this paper, a novel microstrip bandstop filter by etching a square split ring in the center of microstrip line is proposed. Low insertion loss in the passband, high rejection level and integrated structure should be mentioned as advantages for this resonator. A transmission line model for this resonator is introduced and its resonant frequency is calculated analytically. Good agreement between the experimental results, full-wave simulation, transmission line model and analytical result has been achieved.
Single-Dose Gentamicin Treatment of Recurrent Urinary Tract Infection in Children with Normal Urinary Tract
H Habib,MH Fallahzadeh
Iranian Journal of Pediatrics , 2003,
Abstract: Urinary tract infection (UTI) in children is usually treated with orally administered antibiotics for 7–10 days. Because of the unreliability of the patient compliance with the prescribed medications and because single-dose aminoglycoside therapy has been shown to be effective in adults with lower UTI, we conducted this retrospective study to asses efficacy of a single dose of gentamicin in patients with anatomically normal urinary tract, who had recurrent UTI. In this study 79 episodes of UTI in 43 patients treated with gentamicin (41 with single-dose and 38 with conventional method of 7-10 days). All patients, except 7 (2 in conventional therapy and 5 in single-dose group), received both methods of therapy in different episodes of infection. Isolated organisms from patients in single-dose group consisted of E. coli (90.4%), Klebsiella (7.3%), and miscellaneous bacteria (2.3%). In conventional therapy group E. coli (87%), Klebsiella (5.2%), and miscellaneous bacteria (7.8%) were isolated. E. coli was the most frequently isolated microorganism in both groups and sensitive to given antibiotics with no exception. 90.26 % of urine cultures were negative in single-dose group and 94.3 % in conventional therapy group 48-72 hours after treatment, the difference was statistically not significant (p=0.36). Cumulative recurrence rate was 56 % in single-dose and 48.6% in conventional therapy group 6 weeks after treatment with no significant difference (p=64%). Relapse rate (recurrence of the same organism and the same sensitivity as for the therapy begin) 6 weeks after treatment) was 57.3 % in single-dose and 33.5 % in conventional therapy group. This difference was also statistically not significant (p=26%). No side effects could be detected in patients who had been treated with single-dose. The results of the study allow the conclusion that in the absence of urinary tract malformations a single-dose treatment of UTI in children will be effective enough.
