Question: What causes Sleep Apnea ?

Answer: When you're awake, throat muscles help keep your airway stiff and open so air can flow into your lungs. When you sleep, these muscles relax, which narrows your throat.
                
Normally, this narrowing doesnt prevent air from flowing into and out of your lungs. But if you have sleep apnea, your airway can become partially or fully blocked because:
                
Your throat muscles and tongue relax more than normal.
                
Your tongue and tonsils (tissue masses in the back of your mouth) are large compared with the opening into your windpipe.
                
You're overweight. The extra soft fat tissue can thicken the wall of the windpipe. This narrows the inside of the windpipe, which makes it harder to keep open.
                
The shape of your head and neck (bony structure) may cause a smaller airway size in the mouth and throat area.
                
The aging process limits your brain signals' ability to keep your throat muscles stiff during sleep. Thus, your airway is more likely to narrow or collapse.
                
Not enough air flows into your lungs if your airway is partially or fully blocked during sleep. As a result, loud snoring and a drop in your blood oxygen level can occur.
                
If the oxygen drops to a dangerous level, it triggers your brain to disturb your sleep. This helps tighten the upper airway muscles and open your windpipe. Normal breathing then starts again, often with a loud snort or choking sound.
                
Frequent drops in your blood oxygen level and reduced sleep quality can trigger the release of stress hormones. These hormones raise your heart rate and increase your risk for high blood pressure, heart attack, stroke, and arrhythmias (irregular heartbeats). The hormones also can raise your risk for, or worsen, heart failure.
                
Untreated sleep apnea also can lead to changes in how your body uses energy. These changes increase your risk for obesity and diabetes.
Question: What are the genetic changes related to alpha thalassemia ?

Answer: Alpha thalassemia typically results from deletions involving the HBA1 and HBA2 genes. Both of these genes provide instructions for making a protein called alpha-globin, which is a component (subunit) of hemoglobin.  People have two copies of the HBA1 gene and two copies of the HBA2 gene in each cell. Each copy is called an allele. For each gene, one allele is inherited from a person's father, and the other is inherited from a person's mother. As a result, there are four alleles that produce alpha-globin. The different types of alpha thalassemia result from the loss of some or all of these alleles.  Hb Bart syndrome, the most severe form of alpha thalassemia, results from the loss of all four alpha-globin alleles. HbH disease is caused by a loss of three of the four alpha-globin alleles. In these two conditions, a shortage of alpha-globin prevents cells from making normal hemoglobin. Instead, cells produce abnormal forms of hemoglobin called hemoglobin Bart (Hb Bart) or hemoglobin H (HbH). These abnormal hemoglobin molecules cannot effectively carry oxygen to the body's tissues. The substitution of Hb Bart or HbH for normal hemoglobin causes anemia and the other serious health problems associated with alpha thalassemia.  Two additional variants of alpha thalassemia are related to a reduced amount of alpha-globin. Because cells still produce some normal hemoglobin, these variants tend to cause few or no health problems. A loss of two of the four alpha-globin alleles results in alpha thalassemia trait. People with alpha thalassemia trait may have unusually small, pale red blood cells and mild anemia. A loss of one alpha-globin allele is found in alpha thalassemia silent carriers. These individuals typically have no thalassemia-related signs or symptoms.
Question: What are the genetic changes related to hypochromic microcytic anemia with iron overload ?

Answer: Mutations in the SLC11A2 gene cause hypochromic microcytic anemia with iron overload. The SLC11A2 gene provides instructions for making a protein called divalent metal transporter 1 (DMT1). The DMT1 protein is found in all tissues, where its primary role is to transport positively charged iron atoms (ions) within cells. In a section of the small intestine called the duodenum, the DMT1 protein is located within finger-like projections called microvilli. These projections absorb nutrients from food as it passes through the intestine and then release them into the bloodstream. In all other cells, including immature red blood cells called erythroblasts, DMT1 is located in the membrane of endosomes, which are specialized compartments that are formed at the cell surface to carry proteins and other molecules to their destinations within the cell. DMT1 transports iron from the endosomes to the cytoplasm so it can be used by the cell.  SLC11A2 gene mutations lead to reduced production of the DMT1 protein, decreased protein function, or impaired ability of the protein to get to the correct location in cells. In erythroblasts, a shortage of DMT1 protein diminishes the amount of iron transported within cells to attach to hemoglobin. As a result, the development of healthy red blood cells is impaired, leading to a shortage of these cells. In the duodenum, a shortage of DMT1 protein decreases iron absorption. To compensate, cells increase production of functional DMT1 protein, which increases iron absorption. Because the red blood cells cannot use the iron that is absorbed, it accumulates in the liver, eventually impairing liver function. The lack of involvement of other tissues in hypochromic microcytic anemia with iron overload is likely because these tissues have other ways to transport iron.
Question: What are the genetic changes related to multiminicore disease ?

Answer: Mutations in the RYR1 and SEPN1 genes cause multiminicore disease.  The severe, classic form of multiminicore disease is usually caused by mutations in the SEPN1 gene. This gene provides instructions for making a protein called selenoprotein N. Although its function is unknown, researchers suspect that this protein may play a role in the formation of muscle tissue before birth. It may also be important for normal muscle function after birth. It is unclear, however, how mutations in the SEPN1 gene lead to muscle weakness and the other features of multiminicore disease.  Atypical forms of multiminicore disease often result from mutations in the RYR1 gene. RYR1 mutations are also associated with an increased risk of malignant hyperthermia. This gene provides instructions for making a protein called ryanodine receptor 1, which plays an essential role in skeletal muscles. For the body to move normally, these muscles must tense (contract) and relax in a coordinated way. Muscle contractions are triggered by the flow of charged atoms (ions) into muscle cells. In response to certain signals, the ryanodine receptor 1 protein forms a channel that releases stored calcium ions within muscle cells. The resulting increase in calcium ion concentration inside muscle cells stimulates muscle fibers to contract.  Mutations in the RYR1 gene change the structure and function of the ryanodine receptor 1 protein. Some mutations may lead to problems with regulation of the RYR1 channel, while other mutations appear to change the shape of the channel in such a way that calcium ions cannot flow through properly. A disruption in calcium ion transport prevents muscles from contracting normally, leading to the muscle weakness characteristic of multiminicore disease.  In some affected families, the genetic cause of the disorder has not been found. Mutations in genes other than SEPN1 and RYR1 may underlie the condition in these families.
Question: What are the symptoms of Prostate Enlargement: Benign Prostatic Hyperplasia ?

Answer: Lower urinary tract symptoms suggestive of benign prostatic hyperplasia may include
                
- urinary frequencyurination eight or more times a day  - urinary urgencythe inability to delay urination  - trouble starting a urine stream  - a weak or an interrupted urine stream  - dribbling at the end of urination  - nocturiafrequent urination during periods of sleep  - urinary retention  - urinary incontinencethe accidental loss of urine  - pain after ejaculation or during urination  - urine that has an unusual color or smell
                
Symptoms of benign prostatic hyperplasia most often come from
                
- a blocked urethra  - a bladder that is overworked from trying to pass urine through the blockage
                
The size of the prostate does not always determine the severity of the blockage or symptoms. Some men with greatly enlarged prostates have little blockage and few symptoms, while other men who have minimally enlarged prostates have greater blockage and more symptoms. Less than half of all men with benign prostatic hyperplasia have lower urinary tract symptoms.3
                
Sometimes men may not know they have a blockage until they cannot urinate. This condition, called acute urinary retention, can result from taking over-the-counter cold or allergy medications that contain decongestants, such as pseudoephedrine and oxymetazoline. A potential side effect of these medications may prevent the bladder neck from relaxing and releasing urine. Medications that contain antihistamines, such as diphenhydramine, can weaken the contraction of bladder muscles and cause urinary retention, difficulty urinating, and painful urination. When men have partial urethra blockage, urinary retention also can occur as a result of alcohol consumption, cold temperatures, or a long period of inactivity.
Question: What is (are) Parathyroid Cancer ?

Answer: Key Points
                    - Parathyroid cancer is a rare disease in which malignant (cancer) cells form in the tissues of a parathyroid gland.    - Having certain inherited disorders can increase the risk of developing parathyroid cancer.     - Signs and symptoms of parathyroid cancer include weakness, feeling tired, and a lump in the neck.    - Tests that examine the neck and blood are used to detect (find) and diagnose parathyroid cancer.    - Certain factors affect prognosis (chance of recovery) and treatment options.
                
                
                    Parathyroid cancer is a rare disease in which malignant (cancer) cells form in the tissues of a parathyroid gland.
                    The parathyroid glands are four pea-sized organs found in the neck near the thyroid gland. The parathyroid glands make parathyroid hormone (PTH or parathormone). PTH helps the body use and store calcium to keep the calcium in the blood at normal levels.     A parathyroid gland may become overactive and make too much PTH, a condition called hyperparathyroidism. Hyperparathyroidism can occur when a benign tumor (noncancer), called an adenoma, forms on one of the parathyroid glands, and causes it to grow and become overactive. Sometimes hyperparathyroidism can be caused by parathyroid cancer, but this is very rare.   The extra PTH causes:          - The calcium stored in the bones to move into the blood.    - The intestines to absorb more calcium from the food we eat.        This condition is called hypercalcemia (too much calcium in the blood).   The hypercalcemia caused by hyperparathyroidism is more serious and life-threatening than parathyroid cancer itself and treating hypercalcemia is as important as treating the cancer.
