  • 17 alpha hydroxylase deficiency
    17 Alpha hydroxylase deficiency syndrome is a very rare disorder of the genes (specifically on steroid biosynthesis) which causes reduced production of sex steroids and glucocorticoids while the mineralocorticoid precursors are observed to have increased synthesis. It is, therefore, an autosomal recessive condition. The absence or deficiency of 17 hydroxylase results into many sexual malformations and illnesses. [read more]

  • 22q11.2 deletion syndrome, rare (NIH)

  • 3C Syndrome
    3C syndrome is also known as cranio-cerebello cardiac (CCC dysplasia) or Ritscher-Schinzel (named after Ritscher and Schinzel who discovered the illness) and is a very rare case of disease. This syndrome is characterized by heart defects or heart malformations and other symptoms that involve the brain. As of 2006, a Kuwaiti medical journal showed that only 30 cases have been reported worldwide and these cases were discovered in Europe and North America. Due to the limited number of cases reported, this disease was classified as a rare type of illness. The molecular basis for this syndrome is still unknown. [read more]

  • 3M Syndrome
    3M syndrome is known by many names. It can also be called as Three M syndrome or dolicospondylic dysplasia; le Merrer syndrome or gloomy syndrome (because prevalent symptoms show malformities on the patients' faces). This is a very rare illness where only 32 patients have been reported to have acquired it. Its name originated from the names of the authors who first described the characteristics of the illness. The authors' names were Miller, J.D., Malvaux P. and the third is McKusick, V.A. No mental retardation has been mentioned as a result of 3M. This disorder is known as an autosomal recessive trait of the genes and can be inherited. [read more]

  • 47 XXY Syndrome
    47 XXY syndrome is popularly known as the Klinefelter's syndrome, or simply, the XXY syndrome. Chromosome aneuploidy causes the occurrence of this condition. The male patients develop an extra X chromosome. Typically, males should have one each of the X and the Y chromosomes. Patients who suffer from this condition have smaller testicles when compared to their normal male counterparts and thus, they acquire problems on infertility. There are very few symptoms to this syndrome and the cases vary among boys and men. The term for this illness was named after an endocrinologist, Harry Klinefelter. 1942 was the year when he first described the XXY syndrome. The patients who suffer with XXY syndrome are called XXY males or 47,XXY males. [read more]

  • 48,XXXX Syndrome
    48 XXXX syndrome is a very rare disorder of the chromosomes where the normal XX combination becomes a quadruple X grouping. This condition is also called tetrasomy X, 48, XXXX or quadruple X and is only seen among females as there is no Y chromosome involved. The first occurrence of this disorder was discovered in 1961 and since then, there are about 100 reported cases globally. [read more]

  • 49 XXXXX Syndrome
    The 49 XXXXX syndrome (also called as Penta X or pentasomy X) is a chromosomal condition that affects females. In a normal setup, females have only two X chromosomes and anything beyond this is abnormal. In the case of Penta X syndrome, there are an additional three X chromosomes which now totals five. The three additional X chromosomes are the ones that cause multiple problems. These extra X chromosomes are formed together with the two healthy chromosomes inside the nucleus of the human body cells. [read more]

  • Abdominal Defects
    Defects of the abdominal wall are comparatively common fetal abnormalities. It occurs in about 1 in every 2,000 births. Majority of these defects of the abdominal wall cannot be detected early on in pregnancy. When a defect is detected, it is necessary to pinpoint what type of defect it is so that proper medication and treatments can be done. There are many types of abdominal wall disorders. Some examples include: gastroschisis, omphalocele, esophageal atresia, and duodenal atresia. [read more]

  • Ablepharon macrostomia syndrome
    Ablepharon macrostomia syndrome or AMS is a very uncommon genetic disorder that can be inherited. This syndrome is characterized by various physical defects which usually affect areas of the face, fingers, skin, and the genitalia (penis symptoms and some defects on the testes). Patients of AMS could also have other malformations on their abdominal walls or on their nipples. Other traits include having underdeveloped eyelids (or Ablepharon); the absence of eyebrows and eyelashes; mouths that look like that of a fish's (also known as Macrostomia); cracked skin; ears that appear to be low-set (also known as pinnae). The eye defects could appear due to ablepharon. Some people with AMS could also have very thin or sparse hair (alopecia); their skin appears to be wrinkled, dry, coarse, or thick; their fingers could also be webbed and with inadequate extension; the genitalia could have external malformations. In very few cases of Ablepharon macrostomia syndrome, the patient could have little or no nipples at all (having small nipples is known as hypoplastic nipples). One of the worst characteristics could be the protrusion of some parts of the large intestine through a dilated portion of the abdominal wall (this condition is called ventral or abdominal hernia). Infants and children who suffer from AMS may have some delays on the development of their language skills. Some of them may manifest signs of mild retardation of the mind while others may grow up to be normal. A disorder that appears to have the same features as Ablepharon macrostomia syndrome is the Barber-say syndrome. The latter is characterized by laxity of the skin; ablepharon; hypertelorism, macrostomia, telecanthus, acute hirsutism, and helix agenesis of the pair of ears. Less common signs of AMS include undescended testes and hernia on the umbilicus. [read more]

  • Acanthocheilonemiasis
    Acanthocheilonemiasis is an uncommon tropical infectious illness which is caused by Acanthocheilonema perstans, a parasite. This parasite causes rashes of the skin, chest and abdominal pains, joint and muscle pains, lumps on the skin and also neurologic defects. This disease is often transmitted when small flies bite the victim and the bite has the parasite with it. The scientific name of the fly that transmits the ?infectious bite' is A.Coliroides. Studies manifest that the white blood cell levels at elevated when the parasite is present in the human body. Acanthocheilonemiasis belongs to the parasitic diseases group which is called nematode or filarial diseases. This disease is often found in Africa only because the parasite is found abundantly on this region. Uganda, specifically, has had a lot of reported cases. A handful of patients were found in South America. Other names for this disease are Acanthocheilonemiasis perstans, Dipetalonema perstans, Mansonella perstans, and Dipetalonemiasis. [read more]

  • Acne rosacea
    Acne rosacea or simply Rosacea is a very common condition which affects over 45 million people all over the world. Although common, it is a misunderstood condition. This often affects white-skinned individuals who are of northwestern European descent. This has been nicknamed as the ?Celtic curse' by some Irish people. This often begins as mere redness and flushing (erythema) right on the center of the face, also the cheeks, forehead and the nose. It can also affect the chest and the neck. As this disorder progresses, other signs come up such as erythema that is semi-permanent; telangiectasia (or the opening of the surface facial blood vessels); small bumps or domed pustules; reddish gritty eyes, stinging or burning sensations, and the most advanced cases manifest rhinophyma or lobulated nose. This disorder is often confused with seborrheic dermatitis or acne vulgaris. It can co-exist with these two conditions and it can affect both sexes (with females thrice more vulnerable). This peaks on the age of 30 to 60. the primary diagnosis of this disease is mainly facial and when the ears or the scalp become involved, it is a suggestion of a different illness. [read more]

  • Acoustic Neuroma
    Acoustic neuroma also known as a vestibular schwannoma is a primary intracranial tumor that is benign. This is a tumor of the cells that form myelin of the CN VIII or vestibulocochlear nerve. Neuroma is a derivation of a Greek word which means ?tumor of the nerve'. The name ?acoustic' is a misnomer because the tumor hardly occurs from the cochlear or acoustic part of the vestibulocochlear nerve. The precise medical name is vestibular schwannoma. This is because it engages the vestibular part of the eighth cranial nerve and it occurs from schwann cells (the cells that are responsible for the peripheral nervous system myelin sheath).

  • Acquired Ichthyosis
    Ichthyosis is an inherited disorder of the skin. This disorder is an extreme type of ichthyosis which can afflict both sexes all over the world. When this disease is acquired because of a causal disorder, although, it is very rare; it is still not known how this occurs. But there are studies that claim that it can result from mutations of the genes. The mutated genes can be passed from one generation onto the next. The mutation is believed to cause the abnormality in the skin's standard lifecycle. Normal people shed dead skin cells unnoticed but patients of ichthyosis produce new cells of the skin at a rate where their rate of shedding could not cope. This way, there is a dead skin cell buildup and the patient's skin would then appear to be dry or scaly. Acquired ichthyosis often occurs in adulthood. It could occur before or after a systemic condition diagnosis. [read more]

  • Acyl-CoA dehydrogenase, very short chain, deficiency of
    Short Chain Acyl-CoA Dehydrogenase Deficiency (SCADD) is a condition in which the body fails to oxidize fatty acids because an enzyme is either missing or not functioning correctly. Short-chain acyl-coenzyme A (CoA) dehydrogenase deficiency (SCAD) is a rare condition that stops the body from converting certain fats into energy, especially during periods without food (fasting). People affected with this disorder are not able to break down a certain group of fats called short-chain fatty acids efficiently. Some affected infants will display vomiting, low blood sugar (hypoglycemia), a lack of energy (lethargy), poor feeding, and failure to gain weight and grow at the expected rate (failure to thrive). Other features of this disorder may include poor muscle tone (hypotonia), developmental delays, seizures, and a small head size (microcephaly). The symptoms of short-chain acyl-CoA dehydrogenase deficiency may be activated by periods of fasting or during illnesses such as viral infections. In some cases, signs and symptoms may not exhibit themselves until adulthood, when some individuals may develop muscle weakness and wasting. Other people with gene mutations that can lead to this disorder may have such mild symptoms that they are never diagnosed. [read more]

  • Adenocarcinoma of the lung
    Adenocarcinoma of the lung (or lung cancer) is the leading cause of cancer deaths in both women and men in the United States and throughout the world. Lung cancer has beaten breast cancer as the leading cause of cancer deaths in women. In 2007, 160,390 people were projected to die from lung cancer in the United States, which is more than the number of deaths from colorectal, breast, and prostate cancer combined. Only about 2% of those diagnosed with lung cancer that has spread to other areas of the body are living five years after the diagnosis, although the survival rates for lung cancers diagnosed at a very early stage are higher, with approximately 49% surviving for five years or longer. Cancer arises when normal cells undergo a transformation that causes them to grow and multiply without the normal controls. The cells form a mass or tumor that varies from the surrounding tissues from which it arises. Tumors are dangerous because they take nutrients, oxygen, and space from healthy cells. [read more]

  • Alagille-Watson Syndrome
    Alagille-Watson syndrome (AWS) is one of the genetic disorders which affect the different systems of the body including the heart and the liver. The symptoms of the AWS are usually manifested during early childhood or infancy. It is hereditary and its prevalence rate is 1 in every 70,000. The symptoms if AWS varies per family that in some cases it is so mild that the symptoms are unnoticeable while in some cases the symptoms may be as severe as to require transplantation of the heart. When the symptom is liver damage, the patient may have Alagille syndrome which includes yellowing of the skin and whites of the eyes, xanthomas, itching and bile duct paucity. The patient may also have congenital heart problem and kidney problems. In other less common cases, the central nervous system is affected. As for the physical manifestation, those with AWS have the same facial features which includes broad forehead, small and pointed chin and deep-set eyes. The Alagille-Watson Syndrome is caused by the mutation in the JAG1 gene. This gene plays an important role in the signaling of cells during the embryonic development. The mutation of the gene then disrupts the signaling and thus it causes developmental errors of the body's system, such as the heart, liver, spinal column and facial features. In those with liver problems caused by the AWS, the bile ducts are narrowed and malformed. This then results in bile build ups and scarring which prevents the proper elimination of wastes in the blood. Usually the child inherits the altered gene from one parent although there are cases wherein the patient develops mutations of the gene. At present, there is still no known cure for the AWS and the treatment given to patients are targeted to the improvement of the affected system of the body, such as improvement of heart or liver condition. At the same time, the treatments are aimed also at reducing the effects of the affected system. For those with liver problems caused by AWS, there are several medications which are effective in improving the bile flow and in reducing the itching and this include Actigall, Atarax, Rifampicin, Cholestyramine and Phenobarbitol. Of course the effectiveness of the medication varies per patient. Doctors also recommend the high dosage of multivitamins especially vitamins A, D, E and K, since with the damage to the bile ducts the body will have difficulty absorbing these important vitamins. For those with heart defects caused by AWC, corrective surgery is sometimes necessary. [read more]

  • Amelogenesis imperfecta
    Amelogenesis imperfecta is a disorder of a person's tooth development, which causes teeth to become discolored, grooved, pitted, prone to breakage, become unusually small and develop other dental abnormalities. This condition produces varying effects and can affect both baby teeth and permanent teeth. Fourteen types of amelogenesis imperfecta exist. Each type is distinguished by specific dental abnormalities present. All types of amelogenesis imperfecta can affect any number of teeth. People with amelogenesis imperfecta develop teeth with abnormal color, such as grey, brown or yellow. Their teeth have greater risk of developing cavities and become hypersensitive to changes in the temperature. It is estimated that 1 in 14,000 people in the U.S. and 1 in 700 people in Sweden suffer from amelogenesis imperfecta. However, the exact incidence of this condition remains uncertain. [read more]

However, this condition can become severe because the inflammation can damage the spinal cord and the brain, which are both in close proximity to the areas affected by meningitis. Since severe meningitis could cause serious neurological damage or death, immediate medical attention and diagnosis is needed. The most common type of meningitis ? infectious meningitis ? can be treated with antibiotics alone, but requires continues observation. Other types of meningitis can be prevented through scheduled immunization. [read more]

  • Bejel
    Bejel, which was previously called endemic syphilis, is a nonsexually transmitted infection caused by treponemal spirochetes closely related to Treponema pallidum, the bacterium that causes the sexually transmitted disease syphilis. Bejel, yaws, and pinta are diseases closely related to syphilis. They mainly occur in the tropics and subtropics. Unlike syphilis, they are transmitted through skin contact, mostly between children living in poor hygienic conditions. Like syphilis, these diseases start with skin sores and have a latent period that is followed by more a destructive disease. Bejel occurs mainly in the warm arid countries like the eastern Mediterranean region and West Africa. Yaws occurs in equatorial countries. Pinta is most common among the Indians of Mexico, Central America, and South America. Although the bacteria that causes bejel, Treponema pallidum endemicum, is morphologically and serologically indistinguishable from Treponema pallidum pallidum, transmission of bejel is not venereal in nature, generally resulting from mouth-to-mouth contact, skin-to-skin contact, or sharing of domestic utensils, and the courses of the two diseases are vary somewhat.

  • Berdon's Syndrome
    Berdon's Syndrome, also known as Megacystis microcolon intestinal hypoperistalsis syndrome (MMIH), is a disorder of newborn babies, most prevalent in females, characterized by constipation and urinary retention, microcolon, giant bladder (or megacystis), hydronephrosis, intestinal hypoperistalis, and dilated small bowel. It results from a dysfunction of the smooth muscle in the abdomen and digestive system. This disorder prevents the intestines, stomach, kidneys, and bladder from functioning correctly. The pathological findings consist of a large quantity of ganglion cells in both dilated and narrow areas of the intestine. It is a familial disturbance of unknown origin. Experts disagree whether inheritance is autosomal dominant or recessive. In 1976, Berdon and company first described the condition in five female infants, two of whom were sisters. All had marked bladder dilatation and some had hydronephrosis and the external appearance of a prune belly. The infants also had microcolon and sverely dilated small intestines. [read more]

The only effective treatments for biliary atresia are certain surgeries, or liver transplantation. [read more]

  • Biliary Cirrhosis
    Primary biliary cirrhosis is a disease in which the bile ducts in the liver are slowly and steadily destroyed. The body has an intricate system of ducts designed specifically to transport bile, which is a fluid produced in the liver. Bile is needed for the proper digestion of fats and helps rid the body of worn-out red blood cells, cholesterol and potentially toxic metals. In primary biliary cirrhosis, the destruction of bile ducts can cause dangerous substances to build up in the liver and sometimes lead to irreversible scarring of liver tissue (or cirrhosis). Many experts consider primary biliary cirrhosis an autoimmune disease in which the body turns against its own cells, although it's possible that genetic and environmental factors also play a part. Primary biliary cirrhosis develops somewhat slowly. Medication can slow the progression of the disease, especially if treatment starts early. [read more]

  • Branchiootorenal Syndrome
    Branchiootorenal (BOR) syndrome is marked by malformations of the outer, middle, and inner ear associated with conductive, sensorineural, or mixed hearing impairment; branchial fistulae and cysts; and renal malformations, ranging from mild renal hypoplasia to bilateral renal agenesis. The presence, severity, and type of branchial arch, otologic, audiologic, and renal abnormality may be different from right side to left side in an affected individual and also among individuals in the same family. Some individuals develop to end-stage renal disease (ESRD) later in life. The name branciootorenal syndrome describes the body systems most frequently affected by this genetic disorder. The term "branchio" refers to the abnormalities of the neck found in people affected with this syndrome. Cysts (lump or swelling that can be filled with fluid) and fistulas (abnormal passage from the throat to the skin) in the neck appear frequently. The term "oto" refers to the ear disorders that are associated with the syndrome. For example, the outer ear can be abnormal in appearance. Hearing loss is also commonly associated to the syndrome. Finally, the term "renal" stands for the kidney problems commonly found in patients with this condition. [read more]

In cases where no cause is detected, the disease is called cryptogenic organizing pneumonia. The clinical characteristics and radiological imaging resemble infectious pneumonia. However, diagnosis is suspected after there is no response to multiple antibiotics, and blood and sputum cultures are found to be negative for organisms. [read more]

  • Bronchitis, Chronic
    Chronic bronchitis is the inflammation, or irritation, of the airways in the lungs. Airways are the tubes in the lungs where air passes through. They are also known as bronchial tubes. When the airways are irritated, thick mucus forms inside of them. The mucus plugs up the airways and makes it hard for the person to get air into your lungs. Symptoms of chronic bronchitis include a cough that produces mucus (sometimes called sputum), breathing difficulties, and a feeling of tightness in the chest. [read more]

  • Bronchopulmonary Dysplasia
    Bronchopulmonary dysplasia involves the abnormal development of lung tissue. It is marked by inflammation and scarring in the lungs. It occurs most often in premature babies, who are born with underdeveloped lungs. "Broncho" is the name of the airways (the bronchial tubes) through which the oxygen we breathe travels into the lungs. "Pulmonary" refers to the lungs' tiny air sacs (alveoli), where carbon dioxide and oxygen are exchanged. "Dysplasia" means abnormal changes in the organization or structure of a group of cells. The cell changes in BPD occur in the smaller airways and lung alveoli, making breathing difficult and causing problems with lung function. [read more]

  • Bruton Agammaglobulinemia
    Bruton agammaglobulinemia was the first immunodeficiency disease to be described. Colonel Ogden Bruton noted in 1952 the absence of immunoglobulins in a young male with a history of pneumonias and other bacterial sinopulmonary infections. Bruton was also the first physician to furnish specific immunotherapy for this X-linked disorder by administering intramuscular injections of immunoglobulin G (IgG). The patient improved but died of chronic pulmonary disease in his fourth decade of life. This disorder is now formally known as X-linked agammaglobulinemia (XLA), and the gene defect has been mapped to the gene that codes for Bruton tyrosine kinase (Btk) at band Xq21.3. The BTK gene is big and consists of 19 exons that encode the 659 amino acids that form the Btk cytosolic tyrosine kinase. Mutations can happen in any area of the gene. Btk is needed for the proliferation and differentiation of B lymphocytes. In the absence of working Btk, mature B cells that express surface immunoglobulin and the marker CD19 are few to absent. The lack of CD19 is readily detected with fluorocytometric assays, and this finding usually easily confirms the diagnosis of XLA in a male. As Bruton originally described, XLA shows itself as pneumonias and other bacterial sinopulmonary infections in 80% of cases. Such infections that start in male infants as maternal IgG antibodies, acquired transplacentally, are lost. Thus, XLA is most often diagnosed when unusually severe or recurrent sinopulmonary infections occur in a male infant younger than 1 year. [read more]

  • Noise Induced Deafness
    Noise Induced Deafness may be a full or partial reduction in the ability to determine and understand sounds. This condition is usually caused by a wide range of environmental factors. Sound waves have varying frequencies and amplitudes. A person who has lost his ability to detect some frequencies and some low-amplitude sounds which should normally be detected is a characteristic of this condition. Whenever humans are exposed to harmful noise and sounds that are too loud and last a long time, the sensitive structures found in the inner ear may be damaged thereby causing noise-induced hearing loss (NIHL) or Noise Induced Deafness. These sensitive structures which are also called hair cells, are small sensory cells found in the inner ear. They convert sound energy into electrical signals which travel towards the brain. Once the hair cells are damaged, they cannot grow back. [read more]

  • Non-Small Cell Lung Cancer
    The non-small cell lung cancers are taken as one group because their prognoses for recovery and treatments are basically the same. There are three main sub-types of non-small cell lung cancer namely adenocarcinoma, squamous cell lung carcinoma and large cell lung carcinoma. Squamous cell lung carcinoma accounts for 31.1% of the cases. This type of non-small cell lung carcinoma usually starts in close proximity to central bronchus. Development of cavities and necrotic tissues within the center of the cancer site is a major and common finding. Squamous cell lung cancers which are well-differentiated often develop and spread at a slower pace compared to other cancer types. Adenocarcinoma accounts for 29.4% of the cases. This type usually starts in peripheral lung tissue. Majority of the cases are related to smoking. Adenocarcinoma is the most common type of lung cancer among non-smokers. Bronchioloalveolar carcinoma is another subtype. Women who are non-smokers are more predisposed to this cancer form and responses to treatment vary. Large cell lung carcinoma accounts for 10.7% of lung cancers. This type grows rapidly and develops near the lung surface. It is poorly differentiated most of the time and has a tendency to metastasize during its early stages. [read more]
