Neonatal screening for sickle cell disease, glucose-6-phosphate dehydrogenase deficiency and a-thalassemia in Qatif and Al Hasa.

Background: Screening programs to determine the frequency of sickle cell, glucose-6-phosphate dehydrogenase deficiency and alpha-thalassemia gene are available in Saudi Arabia, although not used frequently. Greater use of these programs will decrease the morbidity and mortality of Saudi children affected by these disorders.

Patients And Methods: Neonatal hemoglobin electrophoresis and glucose-6-dehydrogenase fluorescent spot tests were performed on newborn babies delivered between December 1992 and December 1993 at the Qatif Central Hospital and at the King Fahad Hospital in Al Hasa.

A severe form of Caudal Regression Syndrome.

Novel and characteristic CFTR mutations in Saudi Arab children with severe cystic fibrosis.

More than 600 different CFTR (cystic fibrosis transmembrane conductance regulator) gene mutations have been identified so far that are considered to cause the fatal genetic disorder cystic fibrosis (CF). We have investigated 15 Arab children from 12 families, who were diagnosed as having CF, for mutations in the coding region and in the flanking intron sequences of the CFTR gene. Six different CFTR mutations were identified including two novel mutations, 1548delG in exon 10 and 406-2A-->G in intron 3.

Splenectomy and acute splenic sequestration crises in sickle cell disease.

Acute splenic sequestration crises (ASSC) is one of the complications of sickle cell disease (SCD) that can be life-threatening due to loss of blood volume. Over a 5-year period, we have treated 19 patients ranging in age from 4 to 32 years with ASSC. There were 14 males and 5 females; 17 had homozygous SCD and the other 2 had sickle thalassemia.
