Identifying anxiety and depressive disorders among primary care patients: A pilot study

ABSTRACT— One stage case‐identification method, using the Arabic Version of the Hospital Anxiety and Depression Scale (HAD) was applied in a pilot study for estimating the prevalence of depressive and anxiety disorders among a group of Saudi primary care attenders. The validity of the Arabic Version of the HAD scale was previously tested and found valid with high sensivity and specificity. The total prevalence rate of depression was 17% and that of anxiety was 16%. Seven percent of the sample suffered both depression and anxiety i.e. the total percentage of patients with depression, anxiety or both was 26%. Higher morbidity of depression was recorded among females and a higher morbidity of anxiety among male patients.

Leukemia in the eastern region of Saudi Arabia: A population-based study (1987-1988).

This is the first population-based data in Saudi Arabia on the incidence of leukemias in the Eastern Region, as conducted by its regional tumor registry. Data on cancer were captured from all health facilities in the region in 1987-1988. Population census was derived from a survey. Data on cancer deaths were obtained from all death registries. Crude, age-specific, age-standardized, and relative age-standardized incidence rates were used as indicators for the incidence of leukemia. There were 124 cases of leukemias registered. The yearly average crude incidence rate was 5.2 and 3.6 per 100,000 for Saudi males and females, respectively. The age-standardized incidence rate was 7.3 and 6.1 per 100,000 per year in Saudi males and females respectively. The relative age-standardized incidence of leukemias in Saudi males and females ranked, respectively, third and second highest on the international scale. Death from leukemia among Saudis was responsible for 8.9% of the total deaths from cancer. Statistical indicators point to a high incidence rate of leukemias in the Eastern Region of Saudi Arabia among Saudis. Leukemia was the third leading cause of death from cancer. The relative age-standardized rate of leukemias among Saudis of either gender rank very high on the international scale.

Pulmonary effects of occupational exposure to Portland cement: a study from eastern Saudi Arabia.

Abstract A cross-sectional study was conducted in a randomly selected factory producing Portland cement in eastern Saudi Arabia to determine the prevalence of respiratory symptoms and diseases and chest x-ray changes consistent with pneumoconiosis in the employees. A sample of 150 exposed and 355 unexposed employees was selected. A questionnaire about respiratory symptoms was completed during an interview. Chest x-rays were read according to the ILO criteria for pneumoconiosis. Dust level was determined by the gravimetric method. Concentrations of personal respirable dust ranged from 2.13 mg/m3 in the kilns to 59.52 mg/m3 in the quarry area. Cough and phlegm were found to be related to cigarette smoking, while wheezing, shortness of breath, and bronchial asthma were related to dust levels. It is recommended that engineering measures be adopted to reduce the dust level in this company, together with health monitoring of exposed employees.

Pulmonary Function of Workers Exposed to Ammonia: A Study in the Eastern Province of Saudi Arabia

Abstract To determine the effect of chronic exposure to ammonia on pulmonary function among ammonia workers, 77 workers were randomly selected from an ammonia factory in the Eastern Province of Saudi Arabia and 355 were selected as controls from the administrative staffs of four industrial groups in Eastern Province. Spirometry was carried out and FEV1 FVC, and FEV1/FVC% were calculated. The ammonia level in the working environment was determined spectrophotometrically. 30% of the air samples had ammonia concentrations that exceeded the threshold limit value. Significant reductions in FEV1% predicted and FVC % predicted were observed in ammonia workers exposed to higher cumulative ammonia levels (above 50 mg/m3-years). FEV1% predicted and FEV1/FVC% were significantly lower in symptomatic than in asymptomatic workers in the exposed group. These findings may raise the possibility that exposure to a high cumulative ammonia level produces a combined restrictive/obstructive ventilatory defect.

Increased Rate of Cholecystectomy after Introduction of Laparoscopic Cholecystectomy in Saudi Arabia

Abstract. A rapid increase in the rate of cholecystectomy was reported in eastern Saudi Arabia between 1977 and 1986. The aim of this study was to determine whether the rate of cholecystectomy in the same region was still rising after the introduction of laparoscopic cholecystectomy. From 1987 to 1995 a total of 24 hospitals in eastern Saudi Arabia were surveyed using a questionnaire. During the 9-year study period, the rate of total cholecystectomy (open and laparoscopic) increased by 91%. Whereas the cholecystectomy rate decreased by 4% per annum from 1987 to 1990, it increased by 63.7% from 1991 to 1995 after the introduction of laparoscopic cholecystectomy. The increase in the rates of cholecystectomy was observed in all age groups and both sexes. Cholecystectomy was, however, most frequent among the age group 45–64 years followed by the age group 25–44 years. Young and female patients were more likely to undergo laparoscopic cholecystectomy than the open procedure. The rise in cholecystectomy rate deserves further evaluation with regard to the following: reasons for the increased rate of cholecystectomy, cholecystectomy-related morbidity and mortality, and the total costs of cholecystectomy.

Risk factors of mental retardation in children attending an educationally subnormal/mental school in Dammam, Saudi Arabia.

The objective of this case control study was no identify the possible associated risk factors of mild mental retardation in children. Sixty-nine parents of mildly mentally retarded (MR group) male children and a similar number of matched parents of normal male children (control) were interviewed using a questionnaire. The MR group was found to belong to the middle and the lower socioeconomic classes. Histories of maternal smoking, skin rash, fever, and less attendance to antenatal clinics during pregnancy were reported significantly more by mothers of the MR group (P = 0.027, 0.008, 0.027 and 0.0018, respectively). Furthermore, these mothers reported more collective occurrence of newborn jaundice, fever, convulsions, incubator need, and head trauma (P = 0.004). More consanguineous marriages were found in the control group (73.9%) as compared to the MR group (59.4%) (P = 0.056). A family history of mental retardation was, however, more in the latter group compared to the former group (P=0.027). The risk of having another mentally retarded member in the family was found to be a higher if the familial degree of another closeness to the mentally retarded member was more. Well planned health education programs, genetic counseling units, and sufficient antenatal and neonatal services are of prime importance.
