Abstract
Background: In recent years, many ill cases with cytomegalovirus reactivation in non-immuno compromised persons reported. Goal of study: to determine the CMV infection in cerebrospinal fluid of aseptic meningoencephalitis children hospitalized in Rasul & Mofid hospital (2005-2007).
Methods: In a cross sectional study 132 cases selected with simple sampling. CMV-DNA in their Cerebro spinal fluids searched by qualitative PCR.
Results: The age range of the study patients was 5 month- 13 years, median age= 2±3.7 years 87(65.9%) male and 45(34.1%) was female. The presenting signs and symptoms were convulsion 77(69.4%) meningitis 25(18.8%), loss of consciousness 47(37%) neurologic defects 15.9%. DNA extrated in 11 cases. Mycoplasma- DNA in 2cases DNA-CMV detected 2(1.5%). Positive DNA HSV found in 7(15.3%) of patients. DNA- HSV type- 15.3% (7/132) cases. An infant 5 month age with developmental delay, microcephaly and recurrent convulsions. A 1 year girl with brain atrophy and progressive hydrocephaly with intracranial shunt
Conclusions: Differentiation between herpes meningoencephalitis and other encephalopathy based on clinical signs in children is too difficult. CMV (1.5%) has lower rate than herpes simplex type-1 (5.7%). In addition to CMV and HSV1 all of herpes family viruses (varicella, herpes 6, 7, Epstein barr virus) could have role in children with meningoencephalitis. In recent years a sensitive, rapid, simple diagnostic test "Single tube Multiplex PCR" in cerebro spinal fluid recommend. Rapid diagnosis and faster treatment is necessary for decreasing mortality and morbidity in all of herpes meningoencephalitis cases

Abstract
Background: Vesicoureteral reflux (VUR) is the retrograde flow of urine from the bladder into the ureter and toward the kidney. Vesicoureteral reflux is the most com-mon inherited disease in urogenital system. Primary VUR is the most common urologi-cal anomaly in children and it has been reported in 30-50% of those who present with urinary tract infection (UTI). The association of vesicoureteral reflux, urinary tract in-fection and renal damage is well known. Current methods for vesicoureteral reflux di-agnosis are unpleasant. Therefore, human leukocyte antigen system not only might help to detect causative gene but also would assists to establish better prognoses tests of this disease. In this study, the relationship between vesicoureteral reflux and HLA-DRB1 and HLA-DQB1 genes were investigated.
Methods: This study applied on forty vesicoureteral reflux confirmed children from Kerman province, Iran. These children have been admitted to the Afzalipour Hospital for UTI and primary VUR for them was proved by voiding cystourethrogram (VCUG). Also, forty children without any VUR sign as control group. DNA was extracted from the whole blood sample and was amplified using sequence-specific priming polymerase chain reaction (PCR-SSP) method. Finally PCR products were evaluated by electropho-resis in 1.5% agarose gel and frequency of alleles and haplotypes were compared by Chi-square test. Significance level was assumed at P< 0.05.
Results: Low-resolution HLA typing showed the frequency of the HLA-DR17 antigen was significantly increased in vesicoureteral reflux children compared to control group (P= 0.039). On the other hand HLA-DR16 was significantly decreased in vesicoureteral reflux group. Also, frequency of HLA-DQ2 was significantly higher in patients com-pared to control group (P= 0.002). DRB1 (11, 17) and DQ (2, 7) haplotypes were also higher in vesicoureteral reflux patients (P= 0.027, P= 0.01).
Conclusion: The HLA cluster might affect on susceptibility to vesicoureteral reflux es-pecially by locus which located close to HLA-DRB1 and HLA-DQB1 genes. This study demonstrates for the first time in Iran. However, further extensive researches with a large number of samples from different populations and ethnicities are required to val-idate the results obtained in this study.

Abstract
Background: Urinary tract infection is one of the most common infectious diseases in children, the most severe form of which is acute pyelonephritis. Vitamin D plays a very important role in regulating the immune system, this study was conducted to compare vitamin D levels in children with urinary tract infections and healthy children in Kerman, Iran in 2020.
Methods: This cross-sectional study was performed on 63 children with pyelonephritis hospitalized in Afzalipour Hospital and 68 healthy children who were referred to Samen Al-Hojaj Clinic in Kerman, Iran from January 2020 to January 2021. Inclusion criteria for patients include the following: a) the presence of clinical signs and symptoms of infection such as fever b) pyuria, neurogenic bladder, urinary stones, chronic renal failure and previous diagnosis of urinary reflux. The case group was evaluated by taking a complete history, completing a questionnaire and clinical examination, and laboratory tests. The two groups were compared in terms of variables of sex, age and vitamin D levels.
|
Results: The mean age of the case group was 34 months and that of the control group was 38 months. The mean serum levels of vitamin D in the case and control groups were 34.66 and 42.9, respectively). P=0.016( Each group was divided into three groups according to the amount of vitamin D, including groups 1, 2 and 3, respectively, with vitamin D levels below 25 nanomoles per liter of deficiency, 25 to 50 inadequate and above 50 as the appropriate amount of vitamin D was considered. There was no significant difference between girls and boys in terms of vitamin D deficiency compared to the three groups of vitamin D levels.
|
Conclusion: Inadequate vitamin D levels are associated with the prevalence of urinary tract infections, and vitamin D supplementation can be a low-risk option for preventing urinary tract infections.

Abstract
Background: Vesicoureteral reflux (urinary reflux) is one of the most common congenital anomalies in children. This study aimed to compare the ureteral opening distance from the midline in children with vesicoureteral reflux (VUR) and healthy children
Methods: This cross-sectional study was performed on the children with pyelonephritis who were referred to Afzalipour Hospital in Kerman, Iran from August 2019 to August 2020. Twenty children with vesicoureteral reflux (urinary reflux) and twenty healthy children were randomly selected. Then children with vesicoureteral reflux (urinary reflux) and healthy children were divided into two groups. The distance from the ureter to the midline in these children was then measured by a radiologist with a Philips affinity 70 ultrasound machine.
|
Results: In both groups (healthy children and ones with vesicoureteral reflux), ninety-five percent of the children were girls. The mean age of the children in the second group (the children with urinary reflux) was 5.8±2.58 years and the mean age of the children in the first group (the healthy children) was 4.75±1.54 years. The mean age difference between the children with urinary reflux and healthy children was not statistically significant (P=0.127). The mean distance of the ureter from the midline in children with vesicoureteral reflux was 11.44±2.60 mm and the mean distance of the ureter from the midline in healthy children was 9.32±2.74 mm. The mean difference distance of the ureter from the midline in children with vesicoureteral reflux (VUR) and healthy children was statistically significant (P=0.002).
Conclusion: Considering that the distance between the ureter and the midline in patients with urinary reflux is significantly longer than non-reflux ureters, it can be used as a non-invasive method for the diagnosis of vesicoureteral reflux (urinary reflux) in children.

Abstract
Background: Tic disturbances are a group of developmental neurological disorders that often occur in childhood because of abrupt and automatic constrictions of muscles. This study aimed to evaluate the serum levels of 25-hydroxyvitamin D in children with a tic disorders.
Methods: This present case-control research was performed on 63 children with tic disorders and 63 children who were healthy and were referred to Besat clinics in Kerman, Iran from October 2019 to October 2020. The clinical information of patients with tic disorders was collected using a questionnaire. Serum vitamin 25(OH) D3 levels were assessed in patients with tic disturbances after identifying tic disorder.
|
Results: In the group of children with tic disorders, the highest number of patients were girls and in the group of children who were healthy, the highest number of patients were girls. The average age of patients in the case group was 10.37±0.31 years old and the average age of patients in the control group was 10.06±0.41 years old. The average age difference between the children with tic disorders and healthy children was not statistically significant (P=0.971). The average body mass index (BMI) in the case group was 16.98±0.35 and the average BMI in the control group was 16.0±84.56. The average body mass index difference between the children with tic and healthy children was not statistically significant (P=0.838). The mean serum Vit 25(OH) D3 levels in the control group were higher than the average serum level of vitamin D in the case group. The mean serum vitamin D level difference between the children with tic disorders and healthy children was statistically considerable (P=0.036).
Conclusion: The results showed that the average serum level of vitamin D in children with tic disorders was significantly lower than in children who were healthy. To investigate and confirm this relationship, more long-term studies with a larger number of patients are needed.

Abstract
Background: Nephrolithiasis is one of the oldest known systemic diseases of kidney and urinary tract in children. This study aimed to compare the serum level of vitamin D in children with nephrolithiasis and healthy children.
Methods: The present descriptive-cross-sectional study was conducted from October 2017 to September 2019. 74 children with kidney stones and 63 healthy children referring to Afzalipour Hospital in Kerman were selected by simple sampling method. Healthy children who were considered as the control group were matched with the case group in terms of age and gender. All patients underwent kidney and urinary tract ultrasound. The diagnosis of kidney stones was based on the radiologist's opinion. Demographic characteristics of patients (age and sex) were recorded. Patients' blood tests were checked for vitamin D and calcium. Descriptive and analytical methods and SPSS software version 21 were used to analyze the data.
|
Results: The average age of children with kidney stones and healthy children was 5.41±1.8 and 10.06±0.41 years old, respectively (P=0.971). The most number of patients were boys (58.1%). 29.7% of patients and 15.9% of healthy children had a family history of kidney stones (P=0.056). 71.6% of patients had unilateral kidney stones and 28% had bilateral kidney stones. The mean serum level of vitamin D was higher in healthy children (P=0.021). The average calcium was higher in children with kidney stones (P=0.001). The average calcium was higher in children with kidney stones who had a family history of kidney stones (P=0.018). Average calcium was higher in children with bilateral kidney stones (11.4±1.1) (P=0.033). The mean calcium was higher in children with kidney stones with vitamin D deficiency (P=0.001) and sufficient vitamin D levels (P=0.037).
Conclusion: The average level of vitamin D serum in healthy children was significantly higher than that of children with kidney stones, and the average level of calcium in children with kidney stones was significantly higher than that of healthy children. Larger studies with more patients are needed to investigate these relationships.
