The Limitations of Cytomegalovirus DNA Detection in Cerebrospinal Fluid of Newborn Infants With Congenital CMV Infection: A Tertiary Care Neonatal Center Experience.

Background: Congenital cytomegalovirus (cCMV) infection of the central nervous system (CNS) can cause ventriculomegaly, gliosis, calcifications and cortical defects. Detection of CMV DNA in cerebrospinal fluid by PCR (CSF-CMV-PCR) is a marker of CNS involvement.

Objective: To evaluate a diagnostic value of the positive CSF-CMV-PCR in cCMV.

Recessive Mutations in POLR3B Encoding RNA Polymerase III Subunit Causing Diffuse Hypomyelination in Patients with 4H Leukodystrophy with Polymicrogyria and Cataracts.

The diagnosis of 4H leukodystrophy (hypomyelination, hypogonadotropic hypogonadism, and hypodontia) is based on clinical findings and magnetic resonance imaging (MRI). Recently, mutations of the genes encoding Pol III (RNA polymerase III) subunit A (POLR3A) and subunit B (POL3B) have been identified as the genetic causes of hypomyelination. We describe two Polish female siblings aged 5 and 10 years with compound heterozygous mutations in POLR3B.

Recommended management of Toxoplasma gondii infection in pregnant women and their children.

Aforesaid recommendations for the management of T.gondii infection, elaborated by the group of experts, are intended for physicians of various specialties in order to standardize and facilitate diagnostic and therapeutic management. Early diagnosis of congenital toxoplasmosis, both symptomatic and asymptomatic, in neonatal period, initiation of adequate treatment and long-term, multispecialist monitoring, including multi-organ rehabilitation of children may prevent or reduce the complications of congenital toxoplasmosis.

Treatment of pediatric epilepsy in Poland.

Background: The many types of childhood epilepsies make the diagnosis and treatment difficult and the outcomes frequently poor. Furthermore, there are few clinical trials in pediatric epilepsy that provide useful results to guide daily practice. Therefore for pediatric neurologists expert opinion may be useful.

EEG abnormalities preceding the epilepsy onset in tuberous sclerosis complex patients - a prospective study of 5 patients.

Tuberous sclerosis complex (TSC) is a multisystem, autosomal dominant disorder characterized by multiple hamartomas development. Epilepsy is the most common symptom appearing in 80-90% of the patients mainly in the first year of life. A prompt and early seizure control is crucial and can prevent development of an epileptic encephalopathy and secondary mental retardation.

Lipoid pneumonia--a case of refractory pneumonia in a child treated with ketogenic diet.

Lipoid pneumonia (LP) is a chronic inflammation of the lung parenchyma with interstitial involvement due to the accumulation of endogenous or exogenous lipids. Exogenous LP (ELP) is associated with the aspiration or inhalation of oil present in food, oil-based medications or radiographic contrast media. The clinical manifestations of LP range from asymptomatic cases to severe pulmonary involvement, with respiratory failure and death, according to the quantity and duration of the aspiration.

Long-term effect of everolimus on epilepsy and growth in children under 3 years of age treated for subependymal giant cell astrocytoma associated with tuberous sclerosis complex.

Background: Tuberous sclerosis complex (TSC) is a genetic disorder characterized by increased mammalian target of rapamycin (mTOR) activation and growth of benign tumors in several organs throughout the body. In young children with TSC, drug-resistant epilepsy and subependymal giant cell astrocytomas (SEGAs) present the most common causes of mortality and morbidity. There are also some reports on the antiepileptic and antiepileptogenic potential of mTOR inhibitors in TSC.

Antiepileptic treatment before the onset of seizures reduces epilepsy severity and risk of mental retardation in infants with tuberous sclerosis complex.

Background: Epilepsy appears in 70-80% of patients with tuberous sclerosis complex, most commonly in the first year of age. Early manifestation of epilepsy is associated with drug-resistant epilepsy and mental retardation in more than 80% of patients. Clinical epileptic seizures are preceded by deterioration of EEG recording thus infants with high risk of epilepsy can be identified.

Cerebral tuber count and its impact on mental outcome of patients with tuberous sclerosis complex.

Purpose: The aim of the study was to reveal the relationships between the tuber count of the brain found in patients with tuberous sclerosis complex (TSC) and their cognitive outcome.

Methods: A single-center, retrospective analysis was performed of patients with documented TSC seen from 1988 to 2010 at the Children's Memorial Health Institute, Warsaw, Poland.

Key Findings: Sixty-two patients were analyzed, and there was a significant correlation between younger age at the first seizure and developmental delay.

Successful antiepileptic drug withdrawal in infants with epilepsy and cytomegalovirus neuroinfection: longitudinal study.

Purpose: A prospective study estimating antiepileptic and antiviral regimens administered to infants with symptomatic epilepsy and human cytomegalovirus (HCMV) neuroinfection followed for at least 4 years.

Methods: Thirty-two infants (19 female, 13 male) with epileptic seizures and HCMV neuroinfection diagnosed during the first year of life. Detection of HCMV DNA by qualitative polymerase chain reaction (PCR) method in cerebrospinal fluid (CSF), blood leukocytes, and urine confirmed the diagnosis.

Infantile spasms and cytomegalovirus infection: antiviral and antiepileptic treatment.

From 1 January 1995 to 31 December 2004, 22 patients (13 males, nine females; age range 2-12mo) with infantile spasms and cytomegalovirus (CMV) infection were treated with intravenous ganciclovir (GCV) and antiepileptic drugs. GCV was given for 3 to 12 weeks with a 1-month interval (one, two, or three courses). Epileptic spasms occurred before (group A: eight patients), simultaneously (group B: eight patients), and after (group C: six patients) a diagnosis of human CMV (HCMV) infection and antiviral treatment.

[Congenital taxoplasmosis in twins in own material].

Little is known about congenital toxoplasmosis in twins. As in singletons fetal infection occurs usually in mothers seroconverted during second or third trimester of pregnancy. Infection affects usually both siblings, but there is posible that one child is not infected, especially in dizygotic pregnancies.

[Longitudinal study of children with bronchopulmonary dysplasia treated with disodium cromoglycate].

In order to improve the quality of life of children born prematurely, who developed chronic lung disease, clinical trials of drugs of different origin are undertaken. The aim of the work was the evaluation of the efficacy of disodium cromoglycate in the treatment of bronchopulmonary dysplasia in children. We retrospectively studied 15 infants with bronchopulmonary dysplasia (BPD) hospitalised in the Infant Care Department of Children's Health Memorial Institute from 01.

[Visual and auditory impairment in children with congenital cytomegalovirus and Toxoplasma gondii infection].

Intrauterine infections are an important cause of hearing and visual impairment in children. The aim of this paper was to evaluate the character and frequency of hearing and visual disturbances in children with congenital toxoplasmosis and cytomegalovirus infection. 38 out of 54 children with congenital toxoplasmosis as well as 34 out of 403 children with congenital human cytomegalovirus disease, with visual/auditory impairment, hospitalized in Infant Department in Children's Memorial Health Institute between 1995-2001 were enrolled in this study.

Detection of cytomegalovirus in infant cerebrospinal fluid by conventional PCR, nested PCR and PCR-Digene.

The possibility of amplification of human cytomegalovirus (HCMV) DNA in cerebrospinal fluid (CSF) for the diagnosis of HCMV central nervous system (CNS) infection in infants was studied. Single-step PCR, nested PCR and PCR-Digene were used to assay CSF specimens from 37 patients. Criteria for patient inclusion in the study were: 1.

Risk factors for cerebral palsy in very low-birthweight infants in the 1980s and 1990s.

One-hundred twenty-nine very low-birthweight infants were treated in Newborn and Infant Care Department of Children's Memorial Health Institute between 1985 and 1994; 89 were taken to prospective neurodevelopmental care. The newborns were divided into two groups. Group I had 38 preterm infants born from 1985 to 1989 and followed up at 7 to 11 years of age.

[Estimate of clinical dynamic in periventricular leukomalacia].

Clinical observations of 68 preterm and term newborns with ultrasonographically diagnosed PVL treated in the Infant Department of the Child Health Center in Warsaw from January 1985 to December 1990 are presented. The most frequent clinical sign in newborns was hypotonia of the lower extremities. Tremors were significantly more frequent in preterms.

[Diagnosis of Edwards syndrome in newborns].

Congenital malformations most useful for the diagnosis of trisomy 18 in the first days of life were defined based on observations of newborns with Edwards syndrome treated at the Child Health Center in 1992-1994. Intrauterine growth retardation, facial skeleton dysmorphy, congenital heart malformation, mainly VSD, extremity malformations, especially of the palms and feet found in the newborn suggest a diagnosis of Edwards syndrome. The need to differentially diagnose trisomy 18 with autosomal recessive syndrome TAR, Roberts and Smith-Lemli-Opitz is stressed.
