Erectile Dysfunction (ED) or Impotence is a condition where a man is unable to develop and maintain an erection during sex. Conditions that lead to impotence are medications such as anti-depressants, kidney failure, diabetes, anxiety, depression and aging. Other causes for ED - Erectile dysfunction include high cholesterol, hypertension and obesity. Low levels of testosterone, metabolic syndrome and atherosclerosis could also lead to impotence.
Lifestyle changes that can help treat erectile dysfunction are reducing stress, quitting smoking and exercising regularly. Oral medications for impotence are Sildenafil and Tadalafil. Viagra is one such popular medication that is used to increase blood flow and relax the muscles in the penis.
Paraplegia is sensory or motor disorder in the lower extremities of the body. The impairment is due to damage caused as a result of congenital deformities or trauma and spinal injuries. The effects of paraplegia are predominantly seen in the thoracic, lumbar and sacral region. The damage caused as a result of paraplegia can lead to other issues such as monoplegia (dysfunction of one organ), paralysis and some times fecal incontinence and impotence.
Spastic paraplegia and flaccid paraplegia are two important forms of the disease which are differentiated based on the location. Flaccid paraplegia is associated with the lesion caused in the spinal cord; which in turn causes two significant forms of myelopathies compressive and non-compressive respectively. The compressive form of paraplegia occurs because of the destruction of the spinal cord due to pressure exerted on it. In most cases the pressures caused are because of underlying medical conditions such as neoplasms, degenerative spinal disease or hematoma. The compressive forms are predominantly located in extradural and subdural regions causing extra medullary and intramedullary complications such as neurofibroma and meningioma.
The lesions caused affect the spinal arteries causing ischemia eventually leading to tissue necrosis in the respective region. This leads to the development of edema in the spinal region causing compression and damage. Because of increased pressure, paraplegia can initiate complications such as pneumonia, pressure sores which are decubitus in origin. Often the pain associated with paraplegia radiates in the region of nerve damage. Vitamin B 12 deficiency also leads to the occurrence of paraplegia of non compressive origin.
Haemochromatosis is characterized by excess iron in the body. Just like lack of iron can cause anemia, excessive levels of iron in the blood are toxic. The effects are damaging since the iron mineral starts building up in the tissue. In many cases, Hemochromatosis is caused due to an inherited abnormality that causes the body to increase absorption of iron from the intestine. This condition is called primary Hemochromatosis. Secondary Hemochromatosis occurs when abnormal red blood cells in the body are destroyed and iron is released.
Causes : Hereditary Hemochromatosis is an autosomal recessive condition. This Hemochromatosis which is known as iron overload, bronze diabetes, hereditary Hemochromatosis and familial Hemochromatosis. Hemochromatosis afflicts nearly 1.5 million people in the United States and it is one of the most common genetic disorders in the US. Approximately one in 9 persons have one abnormal Hemochromatosis gene which works out to 11% of the US population. Since all of us have 2 copies of each gene, these individuals have an abnormal HFE gene and a normal gene. Thus they are called as carriers. Between 1/200 and 1/400 individuals have two abnormal genes for Hemochromatosis and no normal gene. The culprit gene is on chromosome 6, known as HFE.
As it is an autosomal recessive condition, siblings of the Hemochromatosis patients are at 25% risk to be affected as well. But the chances of the person to develop symptoms depends on which gene mutation s/he has in addition to environmental factors. The 2 most common changes in the HFE gene are C282Y and H63D. To complicate things further, the age at which symptoms show up vary widely even within the same family.
Idiopathic Pulmonary Hemosiderosis (IPH), a disorder affecting largely children and young adults, is a similar disorder owing to abnormal accumulation of hemosiderin. Hemosiderin is a protein found in most tissues, but primarily in the liver. It is produced by digestion of hematin, an iron related substance.
Although it affects both sexes in equal proportion, women suffer later in their lives because of the blood loss in menstruation and child birth in their younger ages. This iron dose overload usually affects people in the age group of 30 - 60 years. It is essential to treat this condition lest it lead to heart failure or cirrhosis of the liver. 5% of cirrhosis cases are caused by hereditary Hemochromatosis.
In Hemochromatosis, as the excess iron is deposited in the liver, pancreas, heart, endocrine glands, skin, joints and intestinal lining, it may result in toxicity of the affected organs. Persons suffering from Hemochromatosis tend to feel fatigue and lethargy. There might be joint pain or arthritis. Men might notice impotence and reduced sex drive. Other symptoms of Hemochromatosis are loss of body hair and darkening of skin. Cirrhosis of the liver might occur due to scarring of liver. This is accompanied by abdominal pain, jaundice and enlargement of the liver and spleen. Haemochromatosis can lead to heart failure or abnormal heart rhythms. The patient may show symptoms similar to heart failure, diabetes or cirrhosis of the liver. Changes in the pigment of the skin may occur, like grayness or a tanned/yellow appearance. Idiopathic pulmonary hemosiderosis appears as paleness of the skin. At times, the patient may start spitting of blood from the lungs or bronchial tubes.
Diagnosis: Hemochromatosis is diagnosed through blood tests and liver biopsy. The usual diagnostic methods are genetic blood studies, blood studies of iron, Magnetic Resonance Imaging (MRI), and liver biopsy. Blood studies of transferrin iron saturation and ferritin (a protein that transports iron and liver enzymes) concentration are used to screen for iron overload. Genetic testing is a reliable technique of diagnosis of Hemochromatosis as this method became widely available. Diagnosis of idiopathic pulmonary hemosiderosis begins with blood tests and X-ray studies of the chest area.
Hemochromatosis Treatment: The first option of treatment is therapeutic venesection or phlebotomy ( a process of regular bloodletting, similar to blood donation). Patients may need to undergo these procedures one or two times a week for a year. The frequency of phlebotomy may be reduced subsequently based on the condition of iron build up. For cases of patients who cannot tolerate phlebotomy owing to other medical conditions can be treated with Desferal (Desferrioxamine). Patients suffering from Haemochromatosis must limit the consumption of iron. Some times chelating agents may be prescribed to control the absorption of iron. Excess alcohol consumption must be avoided. Avoid iron supplements and Vitamin C, which aids absorption of iron. Reduction in the intake of supplements containing iron and foods such as uncooked sea food may help manage this condition.
Prevention: Genetic testing might be the most helpful as variable severity has been noted in patients who have 2 C282Y genes compared to patients with 2 H63D genes or one of each. The best screening method may be iron and ferritin studies which are cost effective for the susceptible group of people. At the end of the day, Hemochromatisis is a common, easily and effectively treated condition. The complications arise in diagnosis as the symptoms mimic other medical conditions.
