Evaluation of oral health behavior of female dental hygiene students and interns of Saudi Arabia by using Hiroshima University Dental Behavioural Inventory (HU-DBI).

Aim: To evaluate and compare oral health behavior of female dental hygiene students/interns (stu/int) studying in private and government universities of Saudi Arabia.

Methods: An English version of Hiroshima University Dental Behavioral Inventory (HU-DBI) was self-administered by 85 dental hygiene stu/int of government and private university colleges and responses were collected. Descriptive statistics, Chi-square test, logistic regression models and independent t tests were performed.

Evaluation of commonly used tribal and traditional remedies in Saudi Arabia.

There are several compounds used in traditional prescriptions and as cosmetics, among several tribes in the Kingdom of Saudi Arabia. Nothing pertinent in the literature exists regarding the components and health hazards of these compounds. There are no health education programs to warn the community especially high-risk populations (such as sickle cell anemia and diabetes mellitus patients) of the hazards involved in the use of the traditional preparations.

Thalassemia syndromes in Saudi Arabia. Meta-analysis of local studies.

The geographical distribution of Alpha and Beta-Thalassemias differ markedly. Alpha-Thalassemia being particularly prevalent in Southeast Asia and Beta-Thalassemia in the Mediterranean basin. Thalassemia syndromes are common in Saudi Arabia: the Beta-Thalassemia genes occur with variable frequency in different regions of Saudi Arabia and both B+ and Bo thalassemia have been reported.

Familial thrombocytosis as a recessive, possibly X-linked trait in an Arab family.

Familial thrombocytosis (FT) has previously been described as an autosomal-dominant disorder with manifestations similar to those of sporadic essential thrombocythaemia. We studied an Arab family consisting of four brothers, aged 4-8 years, who had either sustained markedly elevated (> 1000 x 109/l) or moderately elevated (> 500 x 109/l) platelet counts, two healthy sisters and their parents who had normal platelet counts. The four brothers with FT had normal plasma thrombopoietin levels and are currently not presenting with any thrombotic or haemorrhagic complications.

Splenectomy for hematological disorders in the Eastern Province of Saudi Arabia.

Splenomegaly is a common clinical disorder in the Kingdom of Saudi Arabia. Its aetiology is variable and includes portal hypertension due to schistosomal periportal hepatic fibrosis, haemoglobinopathies and lymphoproliferative disorders. At King Fahd Hospital of the University, Al-Khobar in the Eastern Province of the Kingdom, splenectomy is performed frequently for various reasons on patients drawn from all the Provinces.

Clinical features of sickle cell disease in eastern Saudi Arab children.

The clinical features of sickle cell disease (SCD) in Saudi Arab children of eastern origin are presented. One hundred and seventy-three children were diagnosed at birth and followed prospectively from 3 months to up to 4 years of age. There were 87 boys and 86 girls.

Variability of sickle cell disease in the Eastern Province of Saudi Arabia.

The clinical and hematologic features of sickle cell disease in two groups of patients of different ancestral origin, but living in the Eastern Province of Saudi Arabia, are presented. Twenty-eight patients of southwestern origin were matched for gender, age, and diagnosis with an equal number of patients of eastern origin. The disease was diagnosed in all patients at birth, and follow-up study was done on a regular basis.

Infections and sickle cell disease in Eastern Saudi Arabian children.

The rate and pattern of infections in 144 Saudi Arabian children with sickle cell disease (SCD) and matched normal control subjects are reported. All diagnoses of SCD were made at birth by means of screening blood from the umbilical cord. The children were prospectively followed up from birth to 4 years of age.

Pneumococcal infections in eastern Saudi Arabia: serotypes and antibiotic sensitivity patterns.

The serotypes and antibiotic sensitivity patterns of Streptococcus pneumoniae infections were studied in 208 patients. Male to female ratio was 3 to 1. The main underlying diseases were cardiopulmonary disease (53%), sickle cell disease (13%), diabetes mellitus (11%) and malignancies (11%).

Serum immunoglobulin and complement levels in patients with sickle cell anaemia from eastern province of Saudi Arabia.

Serum immunoglobulin (IgG, IgA, IgM) and complement (C3, C4) levels were determined in 61 sickle cell anaemia patients of various age groups and both sexes in their steady state by nephelometry. Serum IgG was found to be consistently elevated in 46% cases of all age groups. Increase in the levels of IgA, IgM and in the complement values (C3, C4) was also observed.

Clinical presentation of systemic lupus erythematosus in Saudi patients.

A study conducted to assess the incidence and clinical expression of systemic lupus erythematosus in the Eastern Province of Saudi Arabia revealed that the disease is uncommon in this region, only 32 cases being recorded in five years. However, the clinical manifestations of the disease are similar to those observed elsewhere.

Pathological fracture of vertebral column in association with sickle cell anemia in Saudi Arabia.

We describe two cases of sickle cell anemia who were admitted in the hospital with the complaint of backache. X-ray examination and bone scan revealed pathological fracture of vertebral column. These cases are of interest since sickle cell anemia in the Eastern part of Saudi Arabia is reported to run a relatively 'benign' course.

Relationship of haemoglobin F and alpha thalassaemia to severity of sickle-cell anaemia in the Eastern Province of Saudi Arabia.

To define the natural history of sickle cell anaemia a cord blood screening programme was initiated and during the first 3 years a total of 129 newborns with FS phenotype were detected, of whom 83 infants were followed up regularly. Forty-three of them had attained the ages of between 1 and 3 years and the analysis of their data revealed that in 21 of 43 cohort children (14 FS and 7 FS + Barts) who had almost identically raised levels of haemoglobin F, the clinical manifestations of the disease appeared to be influenced by the size of the RBC, with the microcytic group having a relatively milder clinical course as compared with the normocytics. Similar observations were made in about 50% (47/93) of non-cohort older children and adults with sickle-cell anaemia, suggesting that alpha thalassaemia in combination with increased levels of fetal haemoglobin was probably an important predictor of the clinical severity in patients with sickle-cell anaemia in the Eastern Province of Saudi Arabia.

Geographical survey of beta S-globin gene haplotypes: evidence for an independent Asian origin of the sickle-cell mutation.

The haplotypes of 152 beta S-chromosomes were characterized in six different population groups. The chromosomes of individuals from Nigeria and from the southwest of the Arabian peninsula have the haplotype - - - - + + - + previously found in west African, Jamaican, and U.S.

Sensorineural hearing loss in sickle cell disease patients in Saudi Arabia.

Among the complications of sickle cell disease, sensorineural deafness is well documented in the Western literature; little is known about it in Saudi Arabian patients, in whom the general pattern of the disease has been reported to be "mild," attributed partly to high levels of HbF. The auditory function of 42 patients with sickle cell anemia was evaluated clinically and audiometrically and compared with 27 normal controls. Sensorineural deafness was observed in 10 (23.

Stage IV non-Hodgkin's lymphoma in children.

Twenty-five children with previously untreated stage IV non-Hodgkin's lymphoma (NHL) were studied. At the time of evaluation 16 patients were disease-free (64%), with a median observation time of 23 months. Intensive chemotherapy for childhood NHL provides a better outlook for these patients, including those who would be considered high-risk acute lymphoblastic leukemia (ALL).

A genetic marker for elevated levels of haemoglobin F in homozygous sickle cell disease?

Ten patients with sickle cell (SS) disease from a Jamaican family were found to have unusually high levels of haemoglobin F for this population. Each of them has inherited one sickle cell gene on a chromosome characterized by an arrangement of restriction fragment length polymorphisms (haplotype) which is very rare in the Jamaican population. Genetic analysis of the family suggests that there is a determinant linked to the beta-globin gene cluster, characterized by this haplotype, which is responsible for increased haemoglobin F production in response to anaemia.
