Sickle cell trait occurred as a natural mutation of the haemoglobin gene. Sickling decreases the cells' flexibility and results in a risk of various complications. (2) The sickling occurs because of a mutation in the haemoglobin gene. The cause is inherited. Sickle-cell anaemia is a form of sickle-cell disease in which there is homozygosity for the mutation that causes HbS.
Depending on how serious the symptoms are, is how long the person will live. They may live as long as a normal person. In LOTS, the body makes small amounts of hex A. People with LOTS inherit the late-onset hex A, gene from both parents or inherit one late-onset gene and one inactive gene. Tay-Sachs disease results from defects in a gene on chromosome 15 that codes for production of the enzyme Hex-A.
Acute Renal Failure Diagnosis: Acute Renal Failure (ARF) Defined: “Acute Renal failure represents a rapid decline in kidney function sufficient to increase blood levels of nitrogenous wastes and impair fluid and electrolyte balance” (Carol Mattson Porth, Glenn Matfin, 2009, pg.855) Pathophysiology: “Acute renal failure is abrupt in onset and often is reversible if recognized early and treated appropriately. It’s caused by Conditions that produce an acute shut down in renal function. ARF can result from decresed blood flow to the kidney (prerenal failure), disorders that disrupt the structures in the kidney (intrinsic or intrarenal failure), or disorders that interfere with the elimination of urine from the kidney (post renal failure).”(Carol Mattson Porth, Glenn Matfin, 2009, pg 855). ARF consequences include HTN, Hyperkalemia, Acidosis, Oliguria (a decrease in urine output less than 400ml/day). These consequences affect all the organ systems in the body.
The predisposing factors for endocarditis include, aging for older people who have aortic stenosis; intravenous drug abuse, presence of prosthetic heart valve, use of intravascular devices which may result in nosocomial like, methicillin resistant staphylococcus aureus (MRSA); and renal dialysis (Lewis et al, 2011, 841-842). Signs and symptoms include fever, chills, weakness, malaise, fatigue and anorexia due to bacterial infection. Joint pain, muscle, pain, back pain, abdominal discomfort, headache, weight loss and clubbing of fingers resulting from heart failure. Black longitudinal streaks in nails bed Petechiae which result from fragments and microorganism embolization of vegetative lesion as evidenced by conjunctiva, lips, buccal mucosa and palate , and ankles, feet and anticubital and popliteal areas. Painful, tender, red or purple, pea-sized lesions may show on fingertips or toes.
Macrovascular disease is the primary cause of death in people with type 2 diabetes mellitus (Gardner and Shoback, 2007). Microvascular disease is part of the link between diabetes mellitus and cardiovascular disease. It is the disease of the small blood vessels such as capillaries and arterioles (Gardner and Shoback, 2007). This disease causes thinking of the basement membrane of the capillaries. When involving the retina it causes diabetic retinopathy, and when affecting the kidney causes diabetic nephropathy (Gardner and Shoback, 2007).
In Tay-Sachs disease, the child inherits mutations in both alleles of a gene (HEXA) on chromosome 15. HEXA is a gene that codes for the alpha subunit of the enzyme β-hexosaminidase A, normally it helps to degrade a lipid called GM2 ganglioside. In Tay-Sachs individuals, excessive accumulation of the GM2 ganglioside accumulates in neurons because of the absent or reduced amount of the enzyme β-hexosaminidase A. The varied and
A baby born with an Omphalocele has a higher risk for complications than a baby with Gastroschisis for many reasons. Gastroschisis is usually the only birth defect the baby has, but it is possible for them to have others. With a Gastroschisis baby, since the intestines are exposed, they could begin too dry out, and the baby may have problems regulating their body heat. There is also a possibility of some of the intestines dying, and they will have to be removed. They also need special care to prevent infection.
Similar disorders include Nager Sydrome and Miller Syndrome. Mutations in the TFOC1 gene are most commonly the cause for Treacher Collins. Mutations in this gene have been proven to affect the production of rRNA. Decreased production of rRNA causes the death of cells affecting the development of facial structure, causing the abnormalities of the face seen in Treacher Collins. Treacher Collins causes downward sloping eyes (these can lead to vision issues), ears may be undersized or completely absent, no ear canal, middle ear bones can be missing affecting hearing, missing cheek bones, underdeveloped jaw, cleft pallet can occur, these facial issues can lead to problems with speech, swallowing, and sometimes breathing.
The Awareness of Sickle Cell and Beta Thalassemia Sickle Cell is an inherited blood disorder that affects hemoglobin in red blood cells. The hemoglobin in people with sickle cell is abnormal (Borgna-Pignatti 101). In order to have sickle cell disease, a person must inherit the disease from both parents. When the red blood cells sickle, they block blood flow throughout blood vessels. Blocked blood flow can cause damage to organs, pain attacks, or death.
The age-dependent reduction in the capacity of degradation of oxidized proteins may be responsible for the build-up of damaged, dysfunctional molecules in the cell (Shringarpure and Davies 2002). It has been suggested that oxidative damage may be an important source of somatic mutations at the basis of the so-called “somatic mutation theory of aging”. This theory hypothesizes that the accumulation of genetic mutations in somatic cells represents the specific cause of senescence (Beckman and Ames
