Nasal polyps are the most common tumors of the nasal cavity. Nasal polyposis can impair a person’s quality of life more than perennial allergic rhinitis. Nasal polyps are soft, jelly-like overgrowths of the lining of the sinuses. They look like grapes on the end of a stalk. Large polyps can bloc the nose and increase the risk of sinusitis. They may be yellowish, grey or pink in colour. They are common and are not cancerous. Nasal polyposis results from chronic inflammation of the nasal and sinus mucous membranes. Chronic inflammation causes a reactive hyperplasia of the intranasal mucosal membrane, which results in the formation of polyps.

Nasal polyps can vary significantly in size. There may be only one but sometimes several develop like a ’small bunch of grapes’ on a stem. Polyps usually affect both nostrils. Nasal polyps can vary greatly in size. There may be only one but sometimes several grow like a ’small bunch of grapes’ on a stem. The cause of the inflammation is certain conditions make nose inflammation and polyps more likely. These include: asthma, allergy to aspirin, cystic fibrosis, and some rare conditions of the nose. Nasal polyps can occur along with many other respiratory diseases, such as allergic rhinitis, chronic sinusitis, asthma, and aspirin allergy.

Nasal polyps also occur in a majority of people with Churg-Strauss syndrome, a rare disease that inflames the blood vessels (vasculitis). Nasal polyps occur in around 1 in 200 people. It appears that nasal polyps are more common in people with non-allergic rhinitis and non-allergic asthma, rather than allergic types of these conditions. Nasal polyps can affect anyone. However, most cases occur in people over the age of 40 years. They are four times more common in men than in women. In general, women are more likely to have nasal polyps than are men. Nasal polyps are uncommon in children.

Medications are the most common treatment for nasal polyps. Surgery may be needed to eliminate larger growths. Topical nasal steroid sprays, such as Flonase and Nasonex, can help decrease the size of nasal polyps and prevent polyps from growing back after surgery. Use allergy shots in an attempt to treat or stop nasal polyps from growing back after surgery. Intranasal corticosteroid sprays reduce the growth of small intranasal polyps are most effective in the postoperative period. Prevention is better than cure. Avoid over-the-counter saline sprays that contain additives, such as benzalkonium, which can actually inflame the mucous lining of your nose.

Marfan syndrome is an inherited disorder that affects connective tissue the fibers that provide the framework and support for your body. Connective tissue is not a single entity, but a catch-all term for everything in your body that keeps you from falling apart. The familiar tendons and ligaments keep bones and muscles together, but other connective tissue is more obscure, like the elastic fibers in the aorta that keep it soft and rubbery. Marfan syndrome is caused by mutations in the FBN1 gene on chromosome 15. People have a pair of FBN1 genes. Because it is dominant, people who have inherited one affected FBN1 gene from either parent will have Marfan’s.

Marfan syndrome affects all of these structures. It only happens to about 1 in every 5,000 people. People with Marfan syndrome have loose tendons and ligaments, less elasticity in the aorta, and longer arms and legs. In the Marfan syndrome, the walls of the major arteries are weakened. The aorta, the main artery that leaves the heart, often is affected. When this occurs, it gets bigger, which can weaken the inner aortic wall. Under strenuous exertion, the aorta wall can tear. Blood can leak through these tears into the aortic wall, separating its layers a process called aortic dissection.

Another problem that may occur if the aortic wall weakens is that an aneurysm may form. Marfan syndrome can be mild to harsh, and the symptoms can vary. People with Marfan syndrome are frequently very tall, thin and loose jointed. Most people with Marfan syndrome have heart and blood vessel problems, such as a weakness in the aorta or heart valves that leak. They may also have problems with their bones, eyes, skin, nervous system and lungs. Different people may need different types of treatment. Some people may not require treatment, but others may need drugs that lower heart rate, blood pressure or both.

If dural ectasia (swelling of the covering of the spinal cord) develops, medication may help minimize any associated pain. Anticoagulant medications such as warfarin are needed after artificial heart-valve placement. Genetic counseling and specialized clinics are available at many academic medical centers for affected persons and family members. Annual evaluations are important to detect any changes in the spine or sternum. This is particularly important in times of rapid growth, such as adolescence. A serious deformity can not only be disfiguring but can also prevent the heart and lungs from functioning properly.

Nocardiosis is an infection caused by bacteria (Nocardia) which live in the soil. It occurs primarily in individuals with weakened immune systems. Nocardiosis is found throughout the world among people of all ages, although it is most common in older people and males. Nocardia infection is a chronic bacterial infection that usually originates in the lungs and tends to spread to other organ systems most commonly the brain and the skin. It may also involve the kidneys, the joints, the heart, the eyes, and the bones. While individuals with normal immune systems can acquire this infection.

The major risk factors for nocardiosis are a weakened immune system or chronic lung disease. Nocardiosis is rare in AIDS patients. It is not transmitted by person-to-person contact. Nocardiosis is typically regarded as an opportunistic infection, but approximately one-third of infected patients are immunocompetent. Nocardiosis occurs in males more frequently than in females, in a ratio of 3:1. This is thought to be related to an exposure frequency difference rather than a sex difference in susceptibility to infection. Nocardiosis usually begins as a subacute pulmonary infection that resembles actinomycosis.

In about one-third of patients, the infection spreads from the blood into the brain, causing brain abscesses. Nocardia is more likely to disseminate locally or hematogenously. The most common symptoms of pulmonary involvement cough, fever, chills, chest ache, weakness, anorexia, and weight loss. Skin or subcutaneous abscesses occur frequently, sometimes as a primary local inoculation. They may appear as firm cellulites, a lymphocutaneous syndrome, or an actinomycetoma. The lymphocutaneous syndrome consists of a primary pyoderma lesion and lymphatic nodules resembling sporotrichosis.

An actinomycetoma starts as a nodule, suppurates, spreads along fascial planes, and drains through chronic fistulas. Treatment of nocardiosis involves bed rest and high doses of medications. Sulfamethoxazole-trimethoprim (Bactrim) is used most frequently. Additional concurrent therapy with an aminoglycoside plus ceftriaxone benefits patients with fulminant disease. With proper antibiotic treatment, full recovery from nocardiosis is likely. Skin lesions may need to be surgically drained or removed. Surgical therapy to drain abscesses is usually helpful; however, brain abscesses may respond to antimicrobial treatment without surgery.

Neurosarcoidosis refers to the neurological manifestations of sarcoidosis. Sarcoidosis is a progressive multisystem disease that commonly influences young adults. Sarcoidosis is a chronic disorder that affects many body systems. Sarcoidosis affects many body systems. Over 90% of cases involve the lungs and may also involve any other area of the body. Sarcoidosis is characterized by an abnormal immune system response that produces deposits of white blood cells and abnormal tissue cells in the affected organ. A small percentage of cases will involve some portion of the nervous system (neurosarcoidosis).

Neurosarcoidosis may simulate any part of the nervous system. Sudden, transient facial palsy (facial weakness) is common with involvement of cranial nerve VII. The condition can also affect a part of the brain called the hypothalamus, which is involved in regulating several body functions such as temperature, sleep, and stress responses. Sarcoidosis occurs in highly variable groups. Neurosarcoidosis is more common in Africans, including those living in the West Indies, than any other people. It is very uncommon in Chinese, Southeast Asians, Inuits, Canadian Indians, and New Zealand Maoris. Slightly more common in women than men.

In the U.S. it is more common in blacks, while in Europe it is more common in whites. The disorder is faintly more common in people aged 25-50, particularly women, but can arise at any age and to either gender. It is very rare in children. When it does affect children, sarcoidosis usually involves the lungs. Weakness of the facial muscles on one side of the face (Bell’s palsy) is a common symptom of neurosarcoidosis. Visual problems may also be the result of papilledema (swelling of the optic disc) due to obstruction by granulomas of the normal cerebrospinal fluid (CSF) circulation.

It can effect headache, seizures, memory loss, hallucinations, irritability, agitation, and changes in mood and behavior. Peripheral neuropathy has been reported. Neurosarcoidosis can show in an acute, explosive fashion or start as a sluggish chronic illness. Treatment is indicated if symptoms are severe or progressive. Corticosteroids or immunosuppressive drugs may relieve symptoms in selected patients. Immunosuppressive drugs such as methotrexate, azathioprine, cyclosporin, and cyclophosphamide, have benefited some individuals. Risperidone and other antipsychotic drugs have been used for the treatment of neurosarcoidosis.

Neurosyphilis is a gradually progressive and destructive infection of the brain or spinal cord. It is considered a life-threatening complication of syphilis. It occurs in untreated syphilis many years after the primary infection. This can lead to destruction in many areas of the nervous system, causing loss of function of a person’s arms or legs, loss of vision, and altered mental abilities. Neurosyphilis can affect many different body systems and may develop over an extended period of time. Neurosyphilis occurs about 10 to 20 years after first being infected with syphilis. It is considered a life-threatening complication of syphilis.

Symptoms of neurosyphilis usually include confusion and irritability, hearing loss, vision problems, decreased ability to concentrate, memory loss, difficulty speaking or understanding speech, tremor of the fingers and lips, mild headaches and disorderly appearance. Other symptoms may involve a wide gait, numbness or tingling of the hands or feet, muscle pain, joint destruction because of lack of sensation and inability to control urine or stool. Neurosyphilis is divided into two major categories. Meningovascular neurosyphilis affects small blood vessels of the outer membrane covering of the brain (meninges), brain, and spinal cord leading to tissue death.

Parenchymatous neurosyphilis refers to the ruination of nerve cells in the brain and spinal cord leading to partial paralysis and pain, urinary incontinence, difficulty walking, balance problems, and vision problems. Parenchymatous neurosyphilis usually develops in 15 to 25 years. People who are also infected with human immunodeficiency virus (HIV) tend to develop signs of neurosyphilis sooner. Antibiotic treatment cures the syphilis infection and stops the progress of neurosyphilis. Penicillin is used to treat neurosyphilis. Penicillin-allergic individuals should be desensitized and then treated with penicillin.

Nephrocalcinosis is a kidney disorder in which there is an increased amount of calcium in the kidneys. Nephrocalcinosis is caused by surplus excretion of calcium by the kidney, renal tubular acidosis, medullary sponge kidney, hypercalcemia (high calcium levels in the blood), renal cortical necrosis, and tuberculosis. Nephrocalcinosis is relatively common in premature infants, partly from intrinsic kidney calcium losses and partly from enhanced calcium excretion when they are given diuretics. Nephrocalcinosis may eventually result in acute obstructive uropathy or chronic obstructive uropathy, leading to eventual kidney failure.

Other causes of Nephrocalcinosis includes rejected renal transplants can give rise to Nephrocalcinosis. Sickle cell disease is a rare cause of nephrocalcinosis. Sickle cell disease is connected to infection. Vitamin B6 deficiency can be related with xanthurenic aciduria that is linked to deficiency of the phosphate dependent enzyme kynureninase. It is a rare cause of ephrocalcinosis. Nephrocalcinosis can be divided into three categories. Chemical nephrocalcinosis: increased concentration of calcium in renal cells, especially the tubular epithelium, causing adverse effects on renal structure and function.

Microscopic nephrocalcinosis: calcium precipitates in crystalline form as oxalate and/or phosphate, but it is only seen with the aid of a microscope. Macroscopic nephrocalcinosis: large areas of calcification can be seen. There are generally no early symptoms. The symptoms associated to nephrocalcinosis may includes urinary hesitancy, dribbling of urinary incontinence, decrease in the force of the urinary stream, stream small and weak, increased urinary frequency or urgency, painful urination (burning or stinging with urination), feeling of incomplete emptying of the bladder and blood in the urine.

Other symptoms of nephrocalcinosis involves nausea, vomiting, swelling, fluid retention, seizures, blood in the vomit or stools and easy bruising or bleeding. The goal of treatment is to reduce symptoms. Aluminum Hydroxide is used in patients with Struvite or infection. Sodium or potassium citrate can be used. Maintain adequate fluid intake to prevent further calcium deposition, development of renal failure and development of renal stones. Calcium supplements and use of medium chain fats may also help with this condition. Prevention is better than cure. Renal tubular acidosis may help prevent nephrocalcinosis.

Nelson’s syndrome is a rare condition. Nelson syndrome is a disorder characterized by abnormal hormone secretion, extension of the pituitary gland (hypophysis), and the development of big and invasive growths known as adenomas. It occurs in an evaluated 15 to 25 percent of people who undergo surgical removal of the adrenal glands for Cushing disease. In Cushing’s disease, blood cortisol is elevated due to excessive secretion of the hormone ACTH by a pituitary adenoma. ACTH signals the adrenal gland to produce cortisol. The hormone ACTH, in excessive amounts, can stimulate pigment production in the skin.

Symptoms related with Nelson syndrome include intense skin discoloration (hyperpigmentation), headaches, vision impairment, and the cessation of menstrual periods in women. Nelson syndrome is more common in women than men. There is no medical treatment that will help to shrink the microadenoma, but drug therapy may assist in alleviating the symptoms caused by a high ACTH. Bromocriptine, cyproheptadine, and caloric acid can reduce ACTH secretion but do not return it to normal. Radiotherapy is important in the treatment of patients with Nelson syndrome.

Radiotherapy, preferably with stereotactic radiation, controls tumor growth in the majority of patients with residual tumor growth after surgery. Fractionated external beam radiotherapy or stereotactic radio surgery can be used depending on tumor size and location. Modern techniques with high power linear accelerators cause less radiation scatter and so less collateral damage. Radiotherapy is associated with serious long-term problems, including learning and memory difficulties, visual damage and risk of secondary tumours. It is the best treatment for large tumors that produce acute compression of the optic apparatus and other vital structures.

Trans-sphenoidal surgery gives the lowest risk of injury of the hypothalamus. If removal is incomplete or where there is invasion, adjunctive irradiation decreases the rate of recurrence and helps the prognosis. Treatment using protons rather than photons has improved effectiveness and has affected a cure in some patients in whom surgery has been unsuccessful. Use of a gamma knife to focus the radiotherapy beam offers a further refinement. Long term assessment of pituitary function is required with hormone replacement therapy as required. Blood pressure should also be monitored.

Maffucci syndrome is a really rare disorder. Maffucci syndrome is a disorder which affects the skin and skeleton, causing benign cartilage tumors, bone deformities, and dark hemangiomas to grow. Maffucci syndrome is characterized by benign overgrowths of cartilage skeletal deformities, and dark red, irregular shaped patches of skin, resulting from benign growths on the skin consisting of a accumulation of blood vessels (hemangiomas). Maffucci syndrome affects both males and females. Patients are normal at birth and the syndrome manifests during childhood and puberty.

The enchondromas involve the extremities and their distribution is asymmetrical. Disfigurations of the extremities are a consequence. Pathological fractures can occur in affected metaphyses and diaphses of the long bones and are common (26%). The risk for sarcomatous degeneration of enchondromas, hemangiomas, or lymphangiomas is 15-30%.Superficial and deep venous malformations frequently protrude as soft nodules or tumors usually on the distal extremities, but they can appear anywhere. Maffucci syndrome appears to be sporadically inherited. Maffucci syndrome has three main types of symptoms. Venous malformation may be superficial or deep.

If in the skin they frequently protrude as soft bluish bumps. Benign cartilage tumor may show anywhere in the body, but are most often found on the hands or feet, or long bones of the arms or legs. The enchondroma may reason the bone to weaken and break. Bone deformities may comprise shortened length of the long bones, resulting in imbalanced arm or leg lengths. Bones may also break because they are weak, and when they heal, they may not support well. Treatment is not indicated in asymptomatic patients if there is no evidence of any malignant transformations. Surgical interventions can right or minimize deformities.

Malakoplakia is a chronic granulomatous inflammatory disorder. Malakoplakia is inflammatory condition which makes its presence known as a papule, plaque or ulceration that generally affects the genitourinary tract. However, it may also be related with other bodily organs. The inflammation is characterized by enlarged, granular macrophages, scattered PMNs, and characteristic concentrically lamellate, calcified structures called Michaelis-Gutman bodies. Microscopically it is characterized by the presence of foamy histiocytes with basophilic inclusions called Michaelis-Gutmann bodies.

Malakoplakia is thought to effect from the inadequate killing of bacteria by macrophages. Therefore, the moderately digested bacteria accumulate in macrophages and leads to a deposition of iron and calcium. The impairment of bactericidal activity manifests itself as the formation of an ulcer, plaque or papule. It most frequently occurs in the genitourinary tract; however, remote cases have been reported in many other organs, including colon, stomach, lung, liver, bone, uterus, and skin. Malakoplakia is related with patients with a history of immunosuppression due to lymphoma, diabetes mellitus and renal transplantation.

Antibiotics are accustomed for treatment of malakoplakia. Antimicrobials directed against gram-negative bacteria, especially E coli, are used to treat patients with malakoplakia. Quinolone antibiotics (e.g., ciprofloxacin) and sulfonamides (e.g., trimethoprim-sulfamethoxazole) are signifying. Bethanechol and ascorbic acid have also been used in the treatment of patients with malakoplakia. Malakoplakia has been reported in patients receiving chemotherapy or immunosuppressive therapy for organ transplantation, as well as various immune deficient states. Therapy with antibiotics that concentrate in macrophages is associated with a high cure rate.

Antibiotic therapy regulate against E coli in combination with surgery provides the best option of cure. Ascorbic acid has been used to increase the cGMP and cyclic adenosine monophosphate levels in monocytes, which may represent an effective strategy for therapy. Surgery combined with antibiotic therapy should be directed against E coli. Vitamins with the ability to induce collagen fibril synthesis are used. Immunosuppressive drug therapy is usually needed to effectively treat malakoplakia. Prevention is better than cure. Immunosuppressive agents should be used with caution in patients with a prior history of malakoplakia.

Malaria is a mosquito-borne disease caused by a parasite, Plasmodium, which infects red blood cells. Infected mosquitoes spread it. People with malaria frequently experience fever, chills, and flu-like disease. Malaria is a main cause of death worldwide. Approximately 300 million people worldwide are affected by malaria and between 1 and 1.5 million people die from it every year, but it is almost wiped out in the United States. The disease is frequently a problem in developing countries with warm climates. If you travel to these countries, you are at risk. People get malaria by being bitten by an infective female Anopheles mosquito.

Only Anopheles mosquitoes can spread malaria and they must have been contaminated through an earlier blood meal taken on a contaminated being. When a mosquito bites an infected person, a little amount of blood is taken in which contains microscopic malaria parasites. About 1 week later, when the mosquito takes its next blood meal, these parasites mix with the mosquito’s saliva and are injected into the person being bitten. Because the malaria parasite is found in red blood cells of an infected person, malaria can also be transmitted through blood transfusion, organ transplant, or the shared employ of needles or syringes contaminated with blood.

Symptoms of malaria comprise fever, headache, and vomiting. Malaria may reason anemia and jaundice (fair coloring of the skin and eyes) because of the loss of red blood cells. Malaria is not extending from person to person like a cold or the flu, and it cannot be sexually transmitted. You cannot get malaria from casual contact with malaria-infected people, such as sitting next to someone who has malaria. Treatment of malaria involves supportive measures as well as exact anti malarial drugs. Anti-malarial drugs can be prescribed to people traveling to areas where malaria is prevalent.

The types of anti-malarial medications prescribed will rely on the drug-resistance patterns in the areas to be visited. Chloroquine is an often used anti-malarial medication, but quinidine or quinine, or the amalgamation of pyrimethamine and sulfadoxine, are given for chloroquine-resistant infections. People on anti-malarial medications may still become infected. Prevention is better than cure. Avoid mosquito bites by wearing protective clothing over the arms and legs and using screens on windows. Use of mosquito nets and insect repellents can decrease the chance of getting infected.
