Abstract Background Pediatric coronavirus disease 2019 infection usually presents with respiratory and gastrointestinal symptoms. In this report we present fulminant meningitis as the main presentation of coronavirus disease 2019 without major signs and symptoms of other organs’ involvement in 3 infants. Cases The first case was a 4 months Iranian male infant with fulminant meningitis as the main presentation of coronavirus disease 2019 without other organ involvement. He was treated as suspected bacterial meningitis but CSF PCR and CSF culture were negative for common meningeal pathogens. On 3rd day, his coronavirus disease 2019 PCR test became positive, while it was negative on 1st day. The second case was a 13 months Iranian male infant with fever, irritability, and photophobia for 24 h before poorly controlled status epilepticus. CSF coronavirus disease 2019 PCR became positive while CSF PCR and CSF culture were negative for other common meningeal pathogens. Seizures were controlled with multiple anti-seizure medications. The third case was a 14 months Iranian female infant with fever and seizure1 hour before admission, leading to poorly controlled status epilepticus despite anti-epileptic therapy 10 h after admission. CSF coronavirus disease 2019 PCR became positive while CSF PCR and CSF culture were negative for other common meningeal pathogens. He was controlled with multiple anti-seizure medications. Conclusion Meningitis of coronavirus disease 2019 should be considered in severely ill pediatric cases with poorly controlled seizures and RBC in CSF smear. Also, pediatricians can consider corticosteroids, remdesivir, and IVIG therapy in these cases.

Background: Regarding risk of bacterial meningitis (BM) after Cochlear implantation (CI), it was suggested to receive polyvalent conjugate vaccine. We aimed to estimate the prevalence of BM post CI in child recipients who do not receive polyvalent vaccine. Methods: We enrolled 371 children who had received cochlear implants from 2007 to 2010. None of them received pre or post implantation polyvalent conjugate vaccine for BM. We followed all of them for BM for 2 years after implantation. Results: We detected only one female case of BM (0.3% of patients) with the age of 24 months. The mean age of noninfected children was 36.7 ± 23.2 months. The education level of parents was "college level or higher" in less than half of them, and about 65% of patients were products of consanguineous marriage. Conclusions: Our findings indicated that the incidence of BM was not higher in our cochlear implanted children who did not receive immunization than patients from countries in which routine vaccination is done. We suggest that although proper immunization is recommended before surgery, this procedure could be performed without vaccination, especially in developing countries that face financial problems for preparing vaccines.

Background: Congenital hypothyroidism (CHT) is one of the most common congenital endocrinal disorders. The prevalence of CHT is estimated about 1 in 3,000 newborns. The prevalence, etiology and associated disorders of abnormal thyroid screening tests are reported in different ranges. In this study, we assessed the pre-term newborns for CHT and associated factors that influence thyroid function. Methods: One hundred newborns with the gestational age fewer than 35 weeks were investigated. Baseline serum thyroid stimulating hormone (TSH) and free thyroxin (FT4) levels were measured during the first 5 days of life and were repeated during the first 5 weeks. We analyzed the effects of demographic factors and the presence of respiratory distress syndrome on the alteration of thyroid function tests during the first 5 weeks of life. Results: The mean gestational age (GA) at delivery was 32.35΁1.97 (range 28 to 35) weeks. CHT was observed in 13(13%) preterm infants. GA was the only factor which affect the FT4 changes over the two weeks follow-up (P < 0.001, b: -2.783, Power: 70.2%) although the differences between baseline and follow-up amount of TSH were not significantly influenced by GA (P = 0.062, power: 46%). However, the adjusted TSH and FT4 serum level changes during follow-up were significantly different between two groups (between CHT and normal, P = 0.006, 0.000, respectively). Conclusions: It seems that thyroid function tests should be repeated in preterm infants, especially for patients with lower gestational age, to confirm the diagnosis of CHT. Also, CHT should be considered among the newborns that are affected by RDS.

This study was undertaken to determine the predisposing factors for renal scarring in children with urinary tract infection. In this prospective cohort study, 176 children with documented urinary tract infection were categorized into four groups: ≤1 year old, 1-2 years old, 2-7 years and 7-14 years old. Ultrasonography and Technetium-99 m-DMSA scan were used to detect the possible abnormalities. Infants under 12 months old presented as the most common group for renal scarring (27 cases, 52.9%), and vesicoureteral reflux (VUR) was diagnosed in 29 cases (56.8%). Fifteen (41.67%) children between the ages of one and two years had renal scar, and VUR was detected in half of the patients. In the third group, 36.3%, and in fourth group, 41.6% of the patients had renal scar. Also, 38.6% in group three and 50% in the final group had VUR. A co-incidental finding that was observed in this study was the high incidence of pseudohypoaldesteronism (PHA) in our patients: in 39.2% of the children in group one, 22.2% in group two and 4% in group three. In group four however, none of the patients had PHA. Risk of scar formation with urinary tract infection (UTI) was higher in the younger age group and in those with recurrent UTIs.

Epilepsy is an important disease with a cumulative incidence of 3% all over the life and more than half of them are started from childhood. In this study we surveyed magnetic resonance imaging (MRI) findings in epileptic children and its relation with clinical and demographic findings in order to find better diagnostic and treatment modalities for these children in the future. In this cross sectional study, we investigated consecutively all 1 to 15-year-old epileptic children who referred to the pediatric neurology outpatient clinic from 2004 to 2010. Two hundred children were enrolled for investigation. There were 85 (42.5%) girls and 115 (57.7%) boys, aged 1 to 15-year-old (7.7±4). 196 (98%) of the children had abnormal electroencephalography (EEG). Abnormal MRI was seen in 57 (28.5%) patients and consisted of brain atrophy (10%), increasing white matter signal intensity in T2-weighted images (8%), benign cysts (5%), brain tumors (4%) and vascular abnormalities (1.5%). Abnormal MRI findings had significant relation with abnormal EEG, age, positive family history for epilepsy, dysmorphic appearance, and abnormal physical exam. Considering 98% EEG abnormalities in these epileptic children, benign nature of MRI findings in most of our cases, the high price of MRI and the small minority of patients who benefit from active intervention as a result of MRI, we suggest to use EEG for confirmation of epilepsy and perform MRI for patient with abnormal physical exams, focal neurologic deficits or focal EEG abnormalities.

"nLeukocyte adhesion deficiency type 1 (LAD 1) is an autosomal recessive hereditary disorder resulting from deficiency of CD18, characterized by recurrent bacterial infections. We report two consanguineous patients with Leukocyte adhesion deficiency type 1( LAD1). These two infant boy patients were referred to us, within a short period of time, with the complaints of recurrent infections at the age of 38 and 75 days -old, respectively. Parents of two patients were first cousins and their grandmothers also were first cousins. The history of delayed umbilical cord separation was shown in both patients. Patient 1 had history of omphalitis, conjunctivitis, skin lesion of groin area and abscess formation of vaccination site, and had infective wound of eye-lid at the last admission. Patient 2 had history of omphalitis and soft tissue infection of right wrist at the last admission. Laboratory findings showed marked leukocytosis and low CD18 levels (6.6% in Patient 1 and 2.4 % in Patient 2). In Patient 1 recurrent infections were treated with antibiotic regimens and received bone marrow transplantation but Patient 2 died because of septicemia, generalized edema, ascites and progression to acute renal failure at 4 months of age. Due to considerable rate of consanguineous marriages in parents of Leukocyte adhesion deficiency patients, sequence analysis especially for prenatal diagnosis in subsequent pregnancies and genetic counseling is recommended.

Sleep problems are common in childhood, but there are limited studies regarding that in Iranian children and awareness of the sleep problems and their complication in Iranian parents. We arranged this study in which parents of children attending for a sick visit or routine growth control to assess whether sleep problems are under-reported at general pediatric visits. In a cross - a sectional study from April 2010 to April 2011 in 301 children aged 2-14 years old attending to pediatric clinics were enrolled. To investigate the general orientation of parents about their child sleep problem we asked them a global question at first regarding sleep of their child. After that, the Persian version of BEARS questionnaire was completed by them. Only 30 (9.9%) parents reported sleep problems in their children in response to primary global question but by collecting the data from BEARS questionnaire it was revealed 45.18% (136/301) of children had one or more of sleep disorders at all. As mentioned 136 (45.18%) children had slept problems of which the most frequent complaint (15.28%) was related to bedtime problems. The second complaint (11.96%) was awakening during the night children. A significant association between sleep problems and child gender was not found. Co-sleeping with parents was found in 55.48% of all children in this study. Despite the high prevalence and adverse effects of sleep disorders, the present study suggests that parents underreport sleep problems at consultation. We suggest children should be assessed for sleep disorders in monitoring and health screening visits.
