Immunogenicity and side-effects of the inactivated hepatitis A vaccine in periodic fever, aphthous stomatitis, pharyngitis, and adenitis patients.

The aim of this study was to compare the immunogenicity and side-effects of hepatitis A virus (HAV) vaccination between periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) patients and healthy controls who have not been previously exposed to HAV. A prospective observational study was carried out of 28 PFAPA patients and 76 controls who received two doses of the vaccine. Immunogenicity was expressed as seroconversion and seroprotection rates; mean HAV-immunoglobulin G concentration was measured at 0, 1, 7 and 18 months.

Short-course Regimens of Liposomal Amphotericin B for the Treatment of Mediterranean Visceral Leishmaniasis in Children: An 11-year Retrospective Study at a Tertiary Care Center.

Background: Visceral leishmaniasis (VL) remains an important public health problem in endemic regions. Current antileishmanial agents share several limitations including potentially serious side effects and the risk of clinical failure.

Objectives: Aim of this study was to examine the effectiveness and safety of short-course liposomal amphotericin B (L-AmB) regimens in the treatment of childhood VL in our area.

Array comparative genomic hybridization as a clinical diagnostic tool in syndromic and nonsyndromic congenital heart disease.

Background: Congenital heart diseases (CHDs) are often associated with other congenital anomalies, dysmorphic features, and developmental delay, and only a few cases of chromosomal abnormalities are detected by conventional cytogenetic techniques. The microarray comparative genomic hybridization (CGH) analysis allows the identification of submicroscopic genomic rearrangements.

Methods: During the past 3 y, 55 of 330 patients referred for array CGH had CHD of unknown etiology plus at least one additional indication of abnormal chromosomal phenotype.

Array-CGH revealed one of the smallest 16q21q22.1 microdeletions in a female patient with psychomotor retardation.

A 28-month-old girl with dysmorphic craniofacial features, microcephaly, hypotonia, psychomotor retardation, failure to thrive and gastrointestinal problems was referred for clinical evaluation. Array-CGH analysis revealed one of the smallest de novo microdeletions on chromosome 16q21q22.1, 2.

Further delineation of novel 1p36 rearrangements by array-CGH analysis: narrowing the breakpoints and clarifying the "extended" phenotype.

High resolution oligonucleotide array Comparative Genome Hybridization technology (array-CGH) has greatly assisted the recognition of the 1p36 contiguous gene deletion syndrome. The 1p36 deletion syndrome is considered to be one of the most common subtelomeric microdeletion syndromes and has an incidence of ~1 in 5000 live births, while respectively the "pure" 1p36 microduplication has not been reported so far. We present seven new patients who were referred for genetic evaluation due to Developmental Delay (DD), Mental Retardation (MR), and distinct dysmorphic features.

An unusual case of Cat-Eye syndrome phenotype and extragonadal mature teratoma: review of the literature.

BACKGROUND Cat-Eye syndrome (CES) with teratoma has not been previously reported. We present the clinical and molecular findings of a 9-month-old girl with features of CES and also a palpable midline neck mass proved to be an extragonadal mature teratoma, additionally characterized by array comparative genomic hybridization (aCGH). RESULTS High resolution oligonucleotide-based aCGH confirmed that the supernumerary marker chromosome (SMC) derived from chromosome 22, as was indicated by molecular cytogenetic analysis with fluorescence in situ hybridization (FISH).

Familial Pelizaeus-Merzbacher disease caused by a 320.6-kb Xq22.2 duplication and the pathological findings of a male fetus.

Background: Pelizaeus-Merzbacher disease (PMD) is a recessive, X-linked leukoencephalopathy attributed to impaired myelination during central nervous system development, caused by defects in the proteolipid protein 1 (PLP1) gene. PMD presents clinical variability, ranging from the severe connatal form to the classic form.

Cases: We report the clinical and molecular findings of two affected males, three carrier females, and an aborted male fetus with familial PMD.

Microdeletion and microduplication 17q21.31 plus an additional CNV, in patients with intellectual disability, identified by array-CGH.

The recognition of the 17q21.31 microdeletion and microduplication syndrome has been facilitated by high resolution oligonucleotide array comparative genome hybridization technology (aCGH). Molecular analysis of the 17q21.
