Leber Congenital Amaurosis Symptoms

Leber congenital amaurosis (LCA) is a congenital cause of severe visual loss. It is an autosomal recessive condition caused by several different mutations in a variety of genes. It is therefore important to identify the cause of the retinopathy using clinical findings and other diagnostic tests to support the diagnosis. Genetic testing has become mandatory to establish the diagnosis.

Leber Congenital Amaurosis Diagnosis

The condition called Leber Congenital Amaurosis (LCA) is an inherited one, caused by the transmission of two copies of a defective or mutated gene, one from each parent, which results in abnormal retinal development and significant or total impairment of its function. The loss of vision results in visual acuity of 20/400 or less.

Prion diseases, also known as transmissible spongiform encephalopathies (TSEs) are dreaded neurological diseases with a progressive course, and are invariably fatal.

What is a Bicuspid Aortic Valve?

A bicuspid aortic valve (BAV) is the most common form of congenital heart disease and is present in about 2% of the population, affecting twice as many males as females. It is an abnormal form of the aortic valve between the heart and the aorta, the great vessel which supplies blood to the whole body except the lungs. In the normal form this is composed of three leaflets which meet securely when they close to keep blood from flowing back into the heart when the lower left heart chamber or ventricle relaxes.

Health Effects of a Gluten Free Diet

Gluten is a family of proteins that make up about 85% to 90% of the protein composition found in wheat, barley, rye and some other grains. It is made up of almost equal proportions of two types of proteins called gliadins and glutenins, of which each has many subtypes. Thus, the genetic diversity of gluten is staggering. However, gluten makes up most of the high protein content of wheat, which is a grain that is the staple food of much of the developing world.

Immunology of Microsporidiosis

Microsporidosis represents an infection with the spore-forming, obligate intracellular protists. Patients suffering from infections with microsporidia are prone to developing enteritis, keratoconjunctivitis and disseminated diseases that involve muscles and other organs.

What are Mandibular Fractures?

Fractures may occur easily in the mandible owing to its anatomical properties and this bone may account for as many as 70% of fractures occurring in the maxillofacial region. It is fairly prominent on the face and its support is not as strong when compared to other facial bones.

Types of Psychosurgery

Psychosurgery is a field of surgery which consists of stereotactic operations on the brain aimed at altering abnormal physiology by severing certain connections between the frontal lobe and the rest of the brain, including the cortex, the nuclei or other brain pathways, which may appear to function normally or abnormally, in order to reduce mental and/or physical suffering in otherwise untreatable patients.
