Quality of Life and Psychological Wellbeing of Breast Cancer Survivors in the Kingdom of Saudi Arabia.

Introduction: Breast cancer is the most common cancer among Saudi population. Breast cancer patients suffer from several negative consequences after treatment and these include pain, fatigue, sexual problems, appearance and body image concerns, with psychological dysfunction. This could affect the patient quality of life and psychological well-being.

Features and incidence of thromboembolic disease: A comparative study between high and low altitude dwellers in Saudi Arabia.

To estimate and compare the incidence of thromboembolic disease among patients who are clinically suspected for VTE among high and low altitude dwellers in Saudi Arabia. A prospective study conducted over two years (2011-2013) conducted in two different geographical areas in Saudi Arabia; Abha City and Riyadh City. Patients clinically suspected with deep vein thrombosis and pulmonary embolism was recruited to the study.

Stroke and renal artery stenosis from Takayasu's arteritis diagnosed in a 57-year-old male patient.

Takayasu arteritis (TA) is a rare chronic granulomatous inflammatory arterial disease of unknown etiology that affects the aorta, its main branches and pulmonary artery. The clinical presentation is nonspecific, with signs and symptoms that vary according to the affected arterial segment. The most commonly affected vessel is the subclavian artery, while renal artery stenosis is relatively uncommon.

Assessment of cylindrospermopsin toxin in an arid Saudi lake containing dense cyanobacterial bloom.

This study reports the presence of the cyanobacterial toxin cylindrospermopisn (CYN) and its producer Cylindrospermopsis raciborskii for the first time in Saudi freshwater sources. C. raciborskii was found in Gazan Dam Lake water with two morphotypes (coiled and straight).

Bonding quality of contemporary dental cements to sandblasted esthetic crown copings.

Aim: To evaluate the shear bond strength of current luting cements to sandblasted crown-coping substrates.

Methods: Specimens of nickel-chromium, pressable glass ceramic, and zirconia crown-coping substrates were sandblasted in three groups (n = 30 each) with 50 (group 1), 110 (group 2), and 250 μm (group 3) alumina particles at a pressure of 250 kPa. Cylinders of glass ionomer, universal resin, and self-adhesive resin cements were then built up on the sandblasted substrate surfaces of each group (n = 10).

Microcystin production in epiphytic cyanobacteria on submerged macrophytes.

Cyanotoxins have been largely studied in planktonic and benthic cyanobacteria, but microcystin (MCYST) production in epiphytic cyanobacteria has not been reported yet. The present study reports for the first time the MCYST production in epiphytic cyanobacteria on submerged macrophytes. During this study, four common submerged macrophytes in eutrophic pond in Saudi Arabia were surveyed for the presence of toxic epiphytic cyanobacteria.

Microcystins in groundwater wells and their accumulation in vegetable plants irrigated with contaminated waters in Saudi Arabia.

The present study describes the presence of toxic cyanobacteria and microcystin (MCYST) concentrations in groundwater wells and tissues of vegetable plants irrigated with well waters in Asir region, southwest of Saudi Arabia. The results revealed the presence of cyanobacteria in all groundwater wells with a dominance of Oscillatoria limentica. This species was found to produce MCYSTs at a concentration of 336 microg g(-1) as determined by enzyme-linked immunosorbent assay (ELISA).

Microcystin-producing blooms of Anabaenopsis arnoldi in a potable mountain lake in Saudi Arabia.

This study reports for the first time the presence of Anabaenopsis arnoldi blooms in Saudi freshwaters. This species has been investigated with high cell densities (3.8 x 10(3)-264 x 10(3) cells mL(-1)) during June-November 2007 in Tendaha Lake, one of the major freshwater sources in Saudi Arabia.

Cyanobacteria and their toxins in treated-water storage reservoirs in Abha city, Saudi Arabia.

Occurrence of toxic cyanobacteria in drinking and recreational waters poses human health at risk as they can release potent toxins into the water. In the present study, open and covered treated-water storage reservoirs as well as their relevant tap waters in Abha city, Saudi Arabia, were surveyed for the presence of cyanobacteria and their toxins. The results revealed the contamination of most open reservoir and tap waters by algae and cyanobacteria, with an abundance of toxigenic species of cyanobacteria.
