Research Excerpts

Toxicity

Thallium (Tl) is a toxic heavy metal and its exposure to the human body causes physiological and biochemical changes. Thallium is slightly more acutely toxic to mammals than mercury, and as acutely toxic as copper to fish.

An autosomal dominant inherited disorder (with a high frequency of spontaneous mutations) that features developmental changes in the nervous system, muscles, bones, and skin, most notably in tissue derived from the embryonic NEURAL CREST. Multiple hyperpigmented skin lesions and subcutaneous tumors are the hallmark of this disease. Peripheral and central nervous system neoplasms occur frequently, especially OPTIC NERVE GLIOMA and NEUROFIBROSARCOMA. NF1 is caused by mutations which inactivate the NF1 gene (GENES, NEUROFIBROMATOSIS 1) on chromosome 17q. The incidence of learning disabilities is also elevated in this condition. (From Adams et al., Principles of Neurology, 6th ed, pp1014-18) There is overlap of clinical features with NOONAN SYNDROME in a syndrome called neurofibromatosis-Noonan syndrome.

A nutritional condition produced by a deficiency of THIAMINE in the diet, characterized by anorexia, irritability, and weight loss. Later, patients experience weakness, peripheral neuropathy, headache, and tachycardia. In addition to being caused by a poor diet, thiamine deficiency in the United States most commonly occurs as a result of alcoholism, since ethanol interferes with thiamine absorption.

Arthritis, Rheumatoid
A chronic systemic disease, primarily of the joints, marked by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. Etiology is unknown, but autoimmune mechanisms have been implicated.		01.9410
Growth Disorders
Deviations from the average values for a specific age and sex in any or all of the following: height, weight, skeletal proportions, osseous development, or maturation of features. Included here are both acceleration and retardation of growth.		01.9410
Hepatitis A
INFLAMMATION of the LIVER in humans caused by a member of the HEPATOVIRUS genus, HUMAN HEPATITIS A VIRUS. It can be transmitted through fecal contamination of food or water.		01.9410
Psoriasis
A common genetically determined, chronic, inflammatory skin disease characterized by rounded erythematous, dry, scaling patches. The lesions have a predilection for nails, scalp, genitalia, extensor surfaces, and the lumbosacral region. Accelerated epidermopoiesis is considered to be the fundamental pathologic feature in psoriasis.		01.9410
Potassium Deficiency
A condition due to decreased dietary intake of potassium, as in starvation or failure to administer in intravenous solutions, or to gastrointestinal loss in diarrhea, chronic laxative abuse, vomiting, gastric suction, or bowel diversion. Severe potassium deficiency may produce muscular weakness and lead to paralysis and respiratory failure. Muscular malfunction may result in hypoventilation, paralytic ileus, hypotension, muscle twitches, tetany, and rhabomyolysis. Nephropathy from potassium deficit impairs the concentrating mechanism, producing POLYURIA and decreased maximal urinary concentrating ability with secondary POLYDIPSIA.

Keratosis
Any horny growth such as a wart or callus.		01.9410
Parapsoriasis
The term applied to a group of relatively uncommon inflammatory, maculopapular, scaly eruptions of unknown etiology and resistant to conventional treatment. Eruptions are both psoriatic and lichenoid in appearance, but the diseases are distinct from psoriasis, lichen planus, or other recognized dermatoses. Proposed nomenclature divides parapsoriasis into two distinct subgroups, PITYRIASIS LICHENOIDES and parapsoriasis en plaques (small- and large-plaque parapsoriasis).		01.9410
Gas Poisoning
Poisoning that results from exposure to gases such as CARBON MONOXIDE; NOBLE GASES; OXYGEN; or NATURAL GAS.		01.9410
Autoimmune Disease

Autoimmune Diseases
Disorders that are characterized by the production of antibodies that react with host tissues or immune effector cells that are autoreactive to endogenous peptides.		01.9410

Blastomycosis
A fungal infection that may appear in two forms: 1, a primary lesion characterized by the formation of a small cutaneous nodule and small nodules along the lymphatics that may heal within several months; and 2, chronic granulomatous lesions characterized by thick crusts, warty growths, and unusual vascularity and infection in the middle or upper lobes of the lung.		01.9410
Candidiasis, Vulvovaginal
Infection of the VULVA and VAGINA with a fungus of the genus CANDIDA.		01.9410
Cryptococcosis
Fungal infection caused by genus CRYPTOCOCCUS.		01.9410
Mycetoma
A chronic progressive subcutaneous infection caused by species of fungi (eumycetoma), or actinomycetes (actinomycetoma). It is characterized by tumefaction, abscesses, and tumor-like granules representing microcolonies of pathogens, such as MADURELLA fungi and bacteria ACTINOMYCETES, with different grain colors.		01.9410
Sporotrichosis
The commonest and least serious of the deep mycoses, characterized by nodular lesions of the cutaneous and subcutaneous tissues. It is caused by inhalation of contaminated dust or by infection of a wound with SPOROTHRIX.		01.9410
Tinea Pedis
Dermatological pruritic lesion in the feet, caused by Trichophyton rubrum, T. mentagrophytes, or Epidermophyton floccosum.		01.9410
Renal Artery Stenosis
[description not available]		01.9410
Renal Artery Obstruction
Narrowing or occlusion of the RENAL ARTERY or arteries. It is due usually to ATHEROSCLEROSIS; FIBROMUSCULAR DYSPLASIA; THROMBOSIS; EMBOLISM, or external pressure. The reduced renal perfusion can lead to renovascular hypertension (HYPERTENSION, RENOVASCULAR).		01.9410
Asystole
[description not available]		01.9410
Heart Arrest
Cessation of heart beat or MYOCARDIAL CONTRACTION. If it is treated within a few minutes, heart arrest can be reversed in most cases to normal cardiac rhythm and effective circulation.		01.9410
Neuroretinitis
[description not available]		01.9410
Retinitis
Inflammation of the RETINA. It is rarely limited to the retina, but is commonly associated with diseases of the choroid (CHORIORETINITIS) and of the OPTIC DISK (neuroretinitis).		01.9410
Affective Psychosis, Bipolar
[description not available]		01.9410
Bipolar Disorder
A major affective disorder marked by severe mood swings (manic or major depressive episodes) and a tendency to remission and recurrence.		01.9410
