Histamine H1 Antagonists, Non-Sedating
A class of non-sedating drugs that bind to but do not activate histamine receptors (DRUG INVERSE AGONISM), thereby blocking the actions of histamine or histamine agonists. These antihistamines represent a heterogenous group of compounds with differing chemical structures, adverse effects, distribution, and metabolism. Compared to the early (first generation) antihistamines, these non-sedating antihistamines have greater receptor specificity, lower penetration of BLOOD-BRAIN BARRIER, and are less likely to cause drowsiness or psychomotor impairment.
Skin Tests
Histamine H1 Antagonists
Drugs that selectively bind to but do not activate histamine H1 receptors, thereby blocking the actions of endogenous histamine. Included here are the classical antihistaminics that antagonize or prevent the action of histamine mainly in immediate hypersensitivity. They act in the bronchi, capillaries, and some other smooth muscles, and are used to prevent or allay motion sickness, seasonal rhinitis, and allergic dermatitis and to induce somnolence. The effects of blocking central nervous system H1 receptors are not as well understood.
Drug Hypersensitivity
Chronic Disease
Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care.

Angioedemas, Hereditary
Hereditary Angioedema Types I and II
Forms of hereditary angioedema that occur due to mutations in the gene for COMPLEMENT C1 INHIBITOR PROTEIN. Type I hereditary angioedema is associated with reduced serum levels of complement C1 inhibitor protein. Type II hereditary angioedema is associated with the production of a non-functional complement C1 inhibitor protein.
Complement C1 Inhibitor Protein
An endogenous 105-kDa plasma glycoprotein produced primarily by the LIVER and MONOCYTES. It inhibits a broad spectrum of proteases, including the COMPLEMENT C1R and the COMPLEMENT C1S proteases of the CLASSICAL COMPLEMENT PATHWAY, and the MANNOSE-BINDING PROTEIN-ASSOCIATED SERINE PROTEASES. C1-INH-deficient individuals suffer from HEREDITARY ANGIOEDEMA TYPES I AND II.

Keratoderma, Palmoplantar
Carcinoma, Merkel Cell
A carcinoma arising from MERKEL CELLS located in the basal layer of the epidermis and occurring most commonly as a primary neuroendocrine carcinoma of the skin. Merkel cells are tactile cells of neuroectodermal origin and histologically show neurosecretory granules. The skin of the head and neck are a common site of Merkel cell carcinoma, occurring generally in elderly patients. (Holland et al., Cancer Medicine, 3d ed, p1245)
Repeated hand urticaria due to contact with fishfood. (1/402)
BACKGROUND: The etiology of urticaria is often difficult to determine. However, in case of repeated circumstance-connected urticaria, the reason may be easily clarifyable. CASE: A 51-year-old healthy woman repeatedly experienced occupational hand urticaria when handling fish food. An unexpected reason for the urticaria was found in that the fishfood contained histamine as a "contaminant". CONCLUSIONS: In fishfood batches, biological degradation can produce histamine and possibly other toxic substances that can lead to occupational health problems. (+info)Genetic linkage of the Muckle-Wells syndrome to chromosome 1q44. (2/402)
The Muckle-Wells syndrome (MWS) is a hereditary inflammatory disorder characterized by acute febrile inflammatory episodes comprising abdominal pain, arthritis, and urticaria. Progressive nerve deafness develops subsequently, and, after several years, the disease is complicated by multiorgan AA-type amyloidosis (i.e., amyloidosis derived from the inflammatory serum amyloid-associated protein) (MIM 191900) with renal involvement and end-stage renal failure. The mode of inheritance is autosomal dominant, but some sporadic cases have also been described. No specific laboratory findings have been reported. The genetic basis of MWS is unknown. Using a genomewide search strategy in three families, we identified the locus responsible for MWS, at chromosome 1q44. Our results indicate that the gene is located within a 13.9-cM region between markers D1S2811 and D1S2882, with a maximum two-point LOD score of 4. 66 (recombination fraction.00) at D1S2836 when full penetrance is assumed. Further identification of the specific gene that is responsible for MWS will therefore provide the first biological element for characterizing MWS, other than doing so on the basis of its variable clinical expression. (+info)Acquired lipoprotein lipase deficiency associated with chronic urticaria. A new etiology for type I hyperlipoproteinemia. (3/402)
Type I hyperlipoproteinemia (type I HLP) is a rare disorder of lipid metabolism characterized by fasting chylomicronemia and reduced postheparin plasma lipoprotein lipase (LPL) activity. Most cases of type I HLP are due to genetic defects in the LPL gene or in its activator, the apolipoprotein CII gene. Several cases of acquired type I HLP have also been described in the course of autoimmune diseases due to the presence of circulating inhibitors of LPL. Here we report a case of type I HLP due to a transient defect of LPL activity during puberty associated with chronic idiopathic urticaria (CIU). The absence of any circulating LPL inhibitor in plasma during the disease was demonstrated. The LPL genotype showed that the patient was heterozygous for the D9N variant. This mutation, previously described, can explain only minor defects in the LPL activity. The presence of HLP just after the onset of CIU, and the elevation of the LPL activity with remission of the HLP when the patient recovered from CIU, indicate that type I HLP was caused by CIU. In summary, we report a new etiology for type I HLP - a transient decrease in LPL activity associated with CIU and with absence of circulating inhibitors. This is the first description of this association, which suggests a new mechanism for type I HLP. (+info)Inhibition of aminopeptidase P potentiates wheal response to bradykinin in angiotensin-converting enzyme inhibitor-treated humans. (4/402)
Bradykinin is a nonapeptide that contributes to the cardioprotective effects of angiotensin-converting enzyme (ACE) inhibitors. During ACE inhibition, an increased proportion of bradykinin is degraded through non-ACE pathways. Studies in animals suggest that aminopeptidase P (EC 3.4.11.9) may contribute to the metabolism of bradykinin. The purpose of the present study was to determine the contribution of aminopeptidase P to the degradation of bradykinin in humans in the presence and absence of ACE inhibition. To do this, we measured the wheal response to intradermal injection of bradykinin (0, 1, or 10 nicrog) in the presence or absence of intradermal administration of the specific aminopeptidase P inhibitor apstatin (5 or 10 microg) and oral administration of the ACE inhibitor quinapril (10 mg) in six healthy subjects. Both bradykinin (ANOVA; F = 101.18, P <.001) and apstatin alone (F = 7.01, P =.049) caused a wheal of dose-dependent size. There was no significant interaction between apstatin and bradykinin (F = 4.94, P =.175). Pretreatment with 10 mg of quinapril significantly shifted the dose-response curve for bradykinin to the left (effect of quinapril; F = 77.96, P <.001) and there was significant interaction between quinapril and bradykinin (F = 7.82, P =.041). The effect of quinapril was significantly potentiated by coinjection of 10 microg of apstatin (effect of apstatin; F = 21.60, P =.006), such that there was significant interactive effect of quinapril and apstatin (F = 20.83, P =.006) on the wheal response to bradykinin. Collectively, these data suggest that aminopeptidase P plays a minor role in the degradation of bradykinin in human skin in the absence of ACE inhibition but contributes significantly to the degradation of bradykinin in the presence of ACE inhibition. (+info)Pharmacodynamic interaction of eltanolone and alfentanil during lower abdominal surgery in female patients. (5/402)
We have studied the influence of eltanolone on intraoperative alfentanil requirements in 18 female patients undergoing lower abdominal surgery receiving target-controlled infusions of eltanolone and alfentanil. While target concentrations of eltanolone were maintained constant, target concentrations of alfentanil changed in response to the presence or absence of responses. With serum eltanolone concentrations increasing from 500 to 2000 ng ml-1, the EC50 of alfentanil for suppression of responses to surgical stimulation decreased from 233 to 9 ng ml-1. The findings suggest that the interaction between eltanolone and alfentanil is synergistic. (+info)Additive-induced urticaria: experience with monosodium glutamate (MSG). (6/402)
In patients with chronic urticaria, the incidence of reactions to any additives, including monosodium glutamate (MSG), is unknown. Although many studies have investigated the association of additives and urticaria, most have been poorly designed. This study sought to determine the prevalence of reactions to additives, including MSG, in patients with chronic urticaria using a rigorous protocol. We studied 65 subjects (44 women, 21 men; ages 14-67). All had urticaria for >6 wk without discernible etiology. Subjects with active urticaria were studied while they were taking the lowest effective dose of antihistamine. Screening challenges to the 11 additives most commonly associated with exacerbations of chronic idiopathic urticaria were performed in a single-blind fashion. The dose of MSG given was 2500 mg. Skin scores were obtained to determine a positive reaction in an objective manner. Subjects with a positive screening challenge were rechallenged (at least 2 wk later) with a double-blind, placebo-controlled protocol as in-patients in our General Clinical Research Center. Two subjects had positive single-blind, placebo-controlled challenges, but neither had a positive double-blind, placebo-controlled challenge. We conclude, with 95% confidence, that MSG is an unusual (<3% at most) exacerbant of chronic idiopathic urticaria. (+info)Identification of a locus on chromosome 1q44 for familial cold urticaria. (7/402)
Familial cold urticaria (FCU) is a rare autosomal dominant inflammatory disorder characterized by intermittent episodes of rash with fever, arthralgias, conjunctivitis, and leukocytosis. These symptoms develop after generalized exposure to cold. Some individuals with FCU also develop late-onset reactive renal amyloidosis, which is consistent with Muckle-Wells syndrome. By analyzing individuals with FCU from five families, we identified linkage to chromosome 1q44. Two-point linkage analysis revealed a maximum LOD score (Zmax) of 8.13 (recombination fraction 0) for marker D1S2836; multipoint linkage analysis identified a Zmax of 10. 92 in the same region; and haplotype analysis defined a 10.5-cM region between markers D1S423 and D1S2682. Muckle-Wells syndrome was recently linked to chromosome 1q44, which suggests that the two disorders may be linked to the same locus. (+info)Medical surveillance of allergy in laboratory animal handlers. (8/402)
Allergic disease is a serious occupational health concern for individuals who have contact with laboratory animals. The principal respiratory symptoms include allergic rhinitis, conjunctivitis, and asthma. Urticaria (" hives") is the most common skin manifestation. The overall prevalence of allergic disease among laboratory animal handlers is about 23%, and respiratory allergy is much more common than skin allergy. Various studies have found annual incidence rates ranging from 2% to 12%. Prevention of animal allergy depends on control of allergenic material in the work environment. Personal protective equipment such as air filtering respirators should be used in addition to the other exposure control technologies where conditions require. Pre-placement evaluation and periodic medical surveillance of workers are important pieces of the overall occupational health program. The emphasis of these medical evaluations should be on counseling and early disease detection. The article gives recommendations for the content of the medical evaluations. (+info)

Acne
In women, the use of combined birth control pills can improve acne.[100] These medications contain an estrogen and a progestin.[101] They work by decreasing the production of androgen hormones by the ovaries and by decreasing the free and hence biologically active fractions of androgens, resulting in lowered skin production of sebum and consequently reduce acne severity.[10][102] First-generation progestins such as norethindrone and norgestrel have androgenic properties and can worsen acne.[15] Although oral estrogens decrease IGF-1 levels in some situations, which could theoretically improve acne symptoms,[103][104] combined birth control pills do not appear to affect IGF-1 levels in fertile women.[101][105] Cyproterone acetate-containing birth control pills seem to decrease total and free IGF-1 levels.[106] Combinations containing third- or fourth-generation progestins, including desogestrel, dienogest, drospirenone, or norgestimate, as well as birth control pills containing cyproterone ...

Abscess
Most people who have an uncomplicated skin abscess should not use antibiotics.[4] Antibiotics in addition to standard incision and drainage is recommended in persons with severe abscesses, many sites of infection, rapid disease progression, the presence of cellulitis, symptoms indicating bacterial illness throughout the body, or a health condition causing immunosuppression.[1] People who are very young or very old may also need antibiotics.[1] If the abscess does not heal only with incision and drainage, or if the abscess is in a place that is difficult to drain such as the face, hands, or genitals, then antibiotics may be indicated.[1] In those cases of abscess which do require antibiotic treatment, Staphylococcus aureus bacteria is a common cause and an anti-staphylococcus antibiotic such as flucloxacillin or dicloxacillin is used. The Infectious Diseases Society of America advises that the draining of an abscess is not enough to address community-acquired methicillin-resistant Staphylococcus ...
Dermatofibroma
... s[4] are hard solitary slow-growing papules (rounded bumps) that may appear in a variety of colours, usually brownish to tan; they are often elevated or pedunculated. A dermatofibroma is associated with the dimple sign; by applying lateral pressure, there is a central depression of the dermatofibroma. Although typical dermatofibromas cause little or no discomfort, itching and tenderness can occur. Dermatofibromas can be found anywhere on the body, but most often they are found on the legs and arms.[5] They occur most often in women; the male to female ratio is about 1:4.[6] The age group in which they most commonly occur is 20 to 45 years. Some physicians and researchers believe dermatofibromas form as a reaction to previous injuries such as insect bites or thorn pricks.[6] They are composed of disordered collagen laid down by fibroblasts. Dermatofibromas are classed as benign skin lesions, meaning they are completely harmless, though they may be confused with a variety of ...
Lichen planus
Cutaneous LP is a self-limiting condition. It usually resolves within 6 to 12 months. Oral LP is a non infectious, chronic inflammatory condition that involves the oral mucosa and may be accompanied by skin lesions. The etiology of oral LP are unknown. It is not clear whether the mechanisms causing isolated oral LP are different from those causing oral LP with cutaneous LP. An immune-mediated mechanism where basal keratinocytes are being targeted as foreign antigens by activated T cells, especially CD8+ T cells, has been proposed.[43] Upregulation of intercellular adhesion molecule-1 (ICAM-1) and cytokines associated with T-helper 1 immune response, may also pay an important role in the pathogenesis of lichen planus. Stress is thought to play a role in the pathogenesis of oral LP. Patients with anxiety and depression are reported more commonly with oral LP if compared to normal healthy individuals.[44][45] Some studies have indicated that stressful events can induce LP lesions in otherwise ...
Molluscum contagiosum
... (MC), sometimes called water warts, is a viral infection of the skin that results in small, raised, pink lesions with a dimple in the center.[1] They may occasionally be itchy or sore.[1] They may occur singularly or in groups.[1] Any area of the skin may be affected, with abdomen, legs, arms, neck, genital area, and face being most common.[1] Onset of the lesions is around 7 weeks after infection.[3] It usually goes away within a year without scarring.[1] MC is caused by a poxvirus called the molluscum contagiosum virus (MCV).[1] The virus is spread either by direct contact including sexual activity or via contaminated objects such as towels.[4] The condition can also be spread to other areas of the body by the person themselves.[4] Risk factors include a weak immune system, atopic dermatitis, and crowded living conditions.[2] Following one infection, it is possible to get reinfected.[9] Diagnosis is typically based on the appearance.[3] Prevention includes hand washing ...
Aphthous stomatitis
Aphthous affectations" and "aphthous ulcerations" of the mouth are mentioned several times in the treatise "Of the Epidemics" (part of the Hippocratic corpus, in the 4th century BC),[22] although it seems likely that this was oral ulceration as a manifestation of some infectious disease, since they are described as occurring in epidemic-like patterns, with concurrent symptoms such as fever. Aphthous stomatitis was once thought to be a form of recurrent herpes simplex virus infection, and some clinicians still refer to the condition as "herpes" despite this cause having been disproven.[23] The informal term "canker sore" is sometimes used, mainly in North America,[24] either to describe this condition generally, or to refer to the individual ulcers of this condition,[25] or mouth ulcers of any cause unrelated to this condition. The origin of the word "canker" is thought to have been influenced by Latin, Old English, Middle English and Old North French.[26] In Latin, cancer translates to ...
Chickenpox
... , also known as varicella, is a highly contagious disease caused by the initial infection with varicella zoster virus (VZV).[3] The disease results in a characteristic skin rash that forms small, itchy blisters, which eventually scab over.[1] It usually starts on the chest, back, and face then spreads to the rest of the body.[1] Other symptoms may include fever, tiredness, and headaches.[1] Symptoms usually last five to seven days.[1] Complications may occasionally include pneumonia, inflammation of the brain, and bacterial skin infections.[6] The disease is often more severe in adults than in children.[7] Symptoms begin 10 to 21 days after exposure to the virus.[2] Chickenpox is an airborne disease which spreads easily through the coughs and sneezes of an infected person.[2] It may be spread from one to two days before the rash appears until all lesions have crusted over.[2] It may also spread through contact with the blisters.[2] Those with shingles may spread chickenpox to those who ...

Dermatitis herpetiformis
In terms of pathology, the first signs of the condition may be observed within the dermis. The changes that may take place at this level may include edema, vascular dilatation, and cellular infiltration. It is common for lymphocytes and eosinophils to be seen. The bullae found in the skin affected by dermatitis herpetiformis are subepidermal and have rounded lateral borders. When looked at under the microscope, the skin affected by dermatitis herpetiformis presents a collection of neutrophils. They have an increased prevalence in the areas where the dermis is closest to the epidermis. Direct IMF studies of uninvolved skin show IgA in the dermal papillae and patchy granular IgA along the basement membrane. The jejunal mucosa may show partial villous atrophy, but the changes tend to be milder than in coeliac disease.[18] Immunological studies revealed findings that are similar to those of coeliac disease in terms of autoantigens. The main autoantigen of dermatitis herpetiformis is epidermal ...
Skin condition
A skin condition, also known as cutaneous condition, is any medical condition that affects the integumentary system-the organ system that encloses the body and includes skin, hair, nails, and related muscle and glands.[1] The major function of this system is as a barrier against the external environment.[2] Conditions of the human integumentary system constitute a broad spectrum of diseases, also known as dermatoses, as well as many nonpathologic states (like, in certain circumstances, melanonychia and racquet nails).[3][4] While only a small number of skin diseases account for most visits to the physician, thousands of skin conditions have been described.[5] Classification of these conditions often presents many nosological challenges, since underlying causes and pathogenetics are often not known.[6][7] Therefore, most current textbooks present a classification based on location (for example, conditions of the mucous membrane), morphology (chronic blistering conditions), cause (skin conditions ...

Callus
Normally, a callus will form on any part of the skin exposed to excess friction over a long period of time. For example, people often develop calluses on the middle finger or ring finger of their dominant hand due to writing with a pen or pencil. Another cause is from playing string instruments like the guitar or the violin; calluses will develop on the four fingers of the hand used in holding the strings down to the fingerboard, and sometimes on the fingers of the hand used for pizzicato or strumming. Weightlifters commonly experience callus on the upper-palm area due to repeated friction. Calluses are also very common on the fingers of rock climbers on almost all of their fingers. There are many activities that can result in the formation of a callus, which may even be viewed as a badge of experience and commitment to the activity. Activities that are notorious for causing calluses include (but are not limited to) construction work, many sports, wood carving, playing musical instruments, use ...
Vitiligo
Phototherapy is considered a second-line treatment for vitiligo.[1] Exposing the skin to light from UVB lamps is the most common treatment for vitiligo. The treatments can be done at home with an UVB lamp or in a clinic. The exposure time is managed so that the skin does not suffer overexposure. Treatment can take a few weeks if the spots are on the neck and face and if they existed not more than 3 years. If the spots are on the hands and legs and have been there more than 3 years, it can take a few months. Phototherapy sessions are done 2-3 times a week. Spots on a large area of the body may require full body treatment in a clinic or hospital. UVB broadband and narrowband lamps can be used,[28][29] but narrowband ultraviolet picked around 311 nm is the choice. It has been constitutively reported that a combination of UVB phototherapy with other topical treatments improves re-pigmentation. However, some vitiligo patients may not see any changes to skin or re-pigmentation occurring. A serious ...
Melasma
Evidence-based reviews found that the most effective therapy for melasma includes a combination of topical agents.[6][5] Triple combination creams formulated with hydroquinone, tretinoin and a steroid component have shown to be more effective than dual combination therapy or hydroquinone alone.[12] More recently, a systematic review found that oral medications also have a role in melasma treatment, and have been shown to be efficacious with a minimal number and severity of adverse events. Oral medications and dietary supplements employed in the treatment of melasma include tranexamic acid, Polypodium leucotomos extract, beta‐carotenoid, melatonin, and procyanidin.[13] Oral medication procyanidin plus vitamins A, C, and E shows promise as safe and effective for epidermal melasma. In an 8-week randomized, double-blind, placebo-controlled trial in 56 Filipino women, treatment was associated with significant improvements in the left and right malar regions, and was safe and well tolerated.[14] ...

Syphilis
The origin of syphilis is disputed.[2] Syphilis was present in the Americas before European contact,[73] and it may have been carried from the Americas to Europe by the returning crewmen from Christopher Columbus's voyage to the Americas, or it may have existed in Europe previously but gone unrecognized until shortly after Columbus's return.[37][74] These are the Columbian and pre-Columbian hypotheses, respectively, with the Columbian hypothesis better supported by the evidence.[37][75][76] However, findings from phylogenetic science suggest that is, in fact, a New World disease.[77] The first written records of an outbreak of syphilis in Europe occurred in 1494 or 1495 in Naples, Italy, during a French invasion (Italian War of 1494-98).[10][37] Since it was claimed to have been spread by French troops, it was initially called the "French disease" by the people of Naples.[78] In 1530, the pastoral name "syphilis" (the name of a character) was first used by the Italian physician and poet Girolamo ...
Marie Antoinette syndrome
The earliest surviving recorded claim of sudden whitening of the hair is represented in the Talmud, by a story of a Jewish scholar who, at the age of 17 years, developed white hair locks due to overwork.[citation needed] Now and again, contemporary cases of accelerated (though not sudden) hair-whitening have been documented, as with bombing victims in the Second World War,[citation needed] and in a case covered in the medical journal Archives of Dermatology in 2009.[4] ...
Herpes simplex
Following active infection, herpes viruses establish a latent infection in sensory and autonomic ganglia of the nervous system. The double-stranded DNA of the virus is incorporated into the cell physiology by infection of the nucleus of a nerve's cell body. HSV latency is static; no virus is produced; and is controlled by a number of viral genes, including latency-associated transcript.[70] Many HSV-infected people experience recurrence within the first year of infection.[14] Prodrome precedes development of lesions. Prodromal symptoms include tingling (paresthesia), itching, and pain where lumbosacral nerves innervate the skin. Prodrome may occur as long as several days or as short as a few hours before lesions develop. Beginning antiviral treatment when prodrome is experienced can reduce the appearance and duration of lesions in some individuals. During recurrence, fewer lesions are likely to develop and are less painful and heal faster (within 5-10 days without antiviral treatment) than those ...
Porphyria cutanea tarda
... is primarily caused by uroporphyrinogen decarboxylase deficiency (UROD). Uroporphyrinogen decarboxylase occurs in nature as a homodimer of two subunits. It participates in the fifth step in heme synthesis pathway, and is active in the cytosol. This enzymatic conversion results in coproporphyrinogen III as the primary product. This is accomplished by the clockwise removal of the four carboxyl groups present in the cyclic uroporphyrinogen III molecule. Therefore, a deficiency in this enzyme causes the aforementioned buildup of uroporphyrinogen and hepta-carboxylic porphyrinogen, and to a lesser extent hexa-carboxylic porphyrinogen, and penta-carboxylic porphyrinogen in the urine, which can be helpful in the diagnosis of this disorder.[16][17] The dermatological symptoms of PCT that include blistering and lesions on sun-exposed areas of the skin are caused by a buildup of porphyrin compounds (specifically uroporphyrinogen) close to the surface of the skin that have been ...
Seborrhoeic dermatitis
The cause of seborrhoeic dermatitis has not been fully clarified.[1][14] The condition is thought to be due to a local inflammatory response to colonization by Malassezia fungi species in sebum-producing skin areas including the scalp, face, chest, back, underarms, and groin.[3][14] This is based on observations of high counts of Malassezia species in skin affected by seborrhoeic dermatitis and on the effectiveness of antifungals in treating the condition.[14] Such species of Malassezia include M. furfur (formerly P. ovale), M. globosa, M. restricta, M. sympodialis, and M. slooffiae.[3] Although Malassezia appears to be the central predisposing factor in seborrhoeic dermatitis, it is thought that other factors are necessary for the presence of Malassezia to result in the pathology characteristic of the condition.[14] This is based on the fact that high counts of Malassezia in the skin alone do not result in seborrhoeic dermatitis.[14] Besides antifungals, the effectiveness of anti-inflammatory ...
Disseminated intravascular coagulation
Under homeostatic conditions, the body is maintained in a finely tuned balance of coagulation and fibrinolysis. The activation of the coagulation cascade yields thrombin that converts fibrinogen to fibrin; the stable fibrin clot being the final product of hemostasis. The fibrinolytic system then functions to break down fibrinogen and fibrin. Activation of the fibrinolytic system generates plasmin (in the presence of thrombin), which is responsible for the lysis of fibrin clots. The breakdown of fibrinogen and fibrin results in polypeptides called fibrin degradation products (FDPs) or fibrin split products (FSPs). In a state of homeostasis, the presence of plasmin is critical, as it is the central proteolytic enzyme of coagulation and is also necessary for the breakdown of clots, or fibrinolysis.[citation needed] In DIC, the processes of coagulation and fibrinolysis are dysregulated, and the result is widespread clotting with resultant bleeding. Regardless of the triggering event of DIC, once ...
Candidiasis
Candida yeasts are generally present in healthy humans, frequently part of the human body's normal oral and intestinal flora, and particularly on the skin; however, their growth is normally limited by the human immune system and by competition of other microorganisms, such as bacteria occupying the same locations in the human body.[41] Candida requires moisture for growth, notably on the skin.[42] For example, wearing wet swimwear for long periods of time is believed to be a risk factor.[43] Candida can also cause diaper rashes in babies.[35] In extreme cases, superficial infections of the skin or mucous membranes may enter the bloodstream and cause systemic Candida infections. Factors that increase the risk of candidiasis include HIV/AIDS, mononucleosis, cancer treatments, steroids, stress, antibiotic usage, diabetes, and nutrient deficiency. Hormone replacement therapy and infertility treatments may also be predisposing factors.[44] Use of inhaled corticosteroids increases risk of candidiasis ...
