Visual and brainstem auditory evoked potentials in infants with severe vitamin B12 deficiency.

Background/aim: Vitamin B12 plays an important role in the development of mental, motor, cognitive, and social functions via its role in DNA synthesis and nerve myelination. Its deficiency in infants might cause neuromotor retardation as well as megaloblastic anemia. The objective of this study was to investigate the effects of infantile vitamin B12 deficiency on evoked brain potentials and determine whether improvement could be obtained with vitamin B12 replacement at appropriate dosages.

Interictal serum S-100B protein levels in intractable epilepsy: a case-control study.

Epilepsy is the most common neurologic disorder of childhood. In approximately 6-14% of all patients with epilepsy, complete seizure control is difficult to achieve with current antiepileptic treatments. Several current studies have shown in both animals and people that the lengthening of epileptic seizures and frequent recurrence increases the likelihood of neuronal damage.

Oxidative imbalance in child and adolescent patients with obsessive compulsive disorder.

Various psychological, social, genetic and biochemical factors are thought to be involved in etiology of obsessive-compulsive disorder (OCD). To the best of our knowledge there are no studies investigating the effects of free radicals in children and adolescents with OCD. This study evaluated total oxidant and antioxidant status, oxidative stress index, and arylesterase and paraoxonase activity in children and adolescents with OCD.

The preoperative and postoperative oxidative status of children with chronic adenotonsillar hypertrophy.

Aim: This study aimed to evaluate the preoperative and postoperative oxidative status of children with chronic adenotonsillar hypertrophy.

Materials And Methods: The study comprised 25 patients with indications for tonsillectomy and/or adenoidectomy following a diagnosis of chronic adenotonsillar hypertrophy and 25 age-gender matched control patients were included to the study. Blood samples were taken from the patients preoperatively and at four weeks postoperatively.

An evaluation of neuropeptide Y status in subacute sclerosing panencephalitis patients.

Aim: This study aimed to evaluate the neuropeptide Y values of patients with subacute sclerosing panencephalitis.

Materials And Methods: The study comprised 38 patients diagnosed with subacute sclerosing panencephalitis at our clinic, who were being routinely followed-up, together with a control group of 36. Using the Risk and Haddad classification for clinical staging, 16 patients were determined as Stage II and 22 patients as Stage III.

Antibiotic sensitivity and resistance in children with urinary tract infection in Sanliurfa.

Objective: This study aimed to evaluate antibiotic resistance in the province of Şanliurfa and to observe any difference between antibiotic resistance rates.

Material And Methods: The study comprised 107 children who presented at the pediatric polyclinic with complaints of urinary tract infection with the diagnosis of urinary tract infection and whose urine cultures exhibited bacterial growth. The patients were analyzed with respect to the frequency of proliferating pathogens, sensitivity to the antibiotics used and the rates of developed resistance to the antibiotics.

Association of interleukin 18, interleukin 2, and tumor necrosis factor polymorphisms with subacute sclerosing panencephalitis.

Subacute sclerosing panencephalitis (SSPE) is a progressive inflammatory and degenerative disorder of the central nervous system. The measles virus (MV) and host and environmental factors are involved in the development of SSPE, but the precise mechanism by which the MV causes SSPE is still unknown. Studies have indicated that in SSPE patients, specific polymorphisms of certain genes are most likely involved in impairing the host's ability to eradicate the MV.

Heart rate variability in patients with atrial septal defect and healthy children.

Objective: Heart rate variability (HRV) measures are altered in various cardiac and non-cardiac situations in children. The autonomic nervous system is assumed to have a role in the pathophysiology of atrial septal defect (ASD). In this study, we evaluated the autonomic system by measuring HRV in children with ASD.
