BACKGROUND Familial Mediterranean fever (FMF) is an autosomal recessive disease characterized by self-limiting recurrent attacks of fever and serosal inflammation, leading to abdominal, thoracic or articular pain. OBJECTIVE To detect variable clinical presentations and genotypic distribution of different groups of FMF patients and the efficacy of(More)
BACKGROUND Viral respiratory infections are associated with nearly 80% of asthma exacerbation episodes. These can have severe adverse outcomes in patients with established asthma. AIM The aim of the study was to identify the viral causes of acute respiratory infection that precipitate acute asthma exacerbation in Egyptian asthmatic children. PATIENTS(More)
BACKGROUND Asthma is the result of a complex interaction between environmental factors and genetic variants that confer susceptibility. The glutathione S-transferases (GSTT1 and GSTM1) are phase II enzymes thought to protect the airways from oxidative stress. Few and contradictory data are available on the association between asthma development and GSTT1(More)
OBJECTIVE To study whether fetal main pulmonary artery (MPA) Doppler indices can predict the development of neonatal respiratory distress syndrome (RDS). STUDY DESIGN This prospective cross-sectional study included pregnant women between 34 and 38+6 weeks gestation. The diagnostic accuracy of MPA Doppler measurements (systolic/diastolic (S/D) ratio, peak(More)
OBJECTIVE To correlate vitamin D level in Egyptian mothers with that of their newborns, and examine risk factors related to maternal vitamin D deficiency. METHODS A cross-sectional study was carried out at the university teaching hospital in Cairo, Egypt. Serum 25(OH) D levels were measured by enzyme-linked immunosorbent assay in 135 pregnant women at ≥37(More)
BACKGROUND In Egypt, around 1 million children are on the streets. Street children's health is an issue that is not well researched. The objective of the current study was to determine the health problems of a targeted group of street children seeking medical care and to generate a hypothesis about the positive/negative role of street children care(More)
Objective This study aims to detect possible differences in fetal brain volumes between growth-restricted fetuses (FGR), small-for-gestational-age (SGA) fetuses with normal Doppler indices, and appropriate-for-gestational-age fetuses (AGA). Study Design Three-dimensional measurements of fetal brain volume and umbilical artery and middle cerebral artery(More)
