Ichthyosis Essay Example for Free
 Ichthyosis EssayWhile the ichthyoses constitute a  or else large spectrum of about 20 cornification disorders that fit the definition and about 10 with more localized symptoms, they  every last(predicate) are  dissimilar permutations of a hyperkeratotic skin disorder that are characterized by an overgrowth and thickening of the corneal layer of the epidermis with localized erythema, and are classified from their  genetic or acquired origin, inheritance patterns, gene defects, etiologically as enzyme deficiencies, structural protein defects, regulatory protein defects, or   other(a)wise, and clinically as a syndromic ichthyosis, non-syndromic ichthyosis, or as a  link condition.    The term ichthyosis is derived from the Greek word ichthys meaning fish. And aptly named as it is, a patient with ichthyosis  impart present with scaly dry fish-like skin. The severity of scaling in ichthyotic patients runs a very broad spectrum, from  frightening to mild, where it blends into the realm of    dry skin, or xerosis. The most minor of the ichthyoses, ichthyosis vulgaris, in its more mild forms, presents with  at large(p) flaking and irritated apperence can be confused with simple xerosis.While the skin of patients with lamellar ichthyosis, is characterized by heavily pigmented,  headquarters (armor)  like armor scales that are both obvious and ofttimes debilitating. And while all forms of ichthyosis present with a flaky or scaly appearance, several other characteristic clinical features are used as hallmarks of a particular types of ichthyosis so as to distinguish them from one another.In general  internal forms  such as lamellar ichthyosis, congenital ichthyosiform erythroderma, epidermolytic hyperkeratosis, and ichthosis bullosa will present at birth with a yellow, tight and shiny, collodion-like membrane which sheds in 2-3 weeks to reveal a flaky dry skin and in cases of ichthyosis bullosa, redness and blistering, especially over flexures.The traits of congenital ichthy   osis, from obvious scaly appearance, to inflexibility and pain, are all permanent and life-long conditions that even after stabilization and  natural selection are strongly inhibitory to normal psychological and sociological development. With such a dramatic  exit in appearance and physical performance, ichthyosis sufferers are very nearly always ostracized as  nestlingren, often with  cast out effects and stunted development. The two  underlying types of ichthyosis are defined by their method of origin as either genetic or acquired.In inherited ichthyosis specified as autosomal dominant, autosomal recessive, and X-linked, a mutation in a gene causes an abnormality in the normal life cycle of skin,  take to a build-up of excess skin either because of the overproduction of the replacement skin cells or because when the time comes when  grey cells  tolerate to be drop off they do not separate very well from the surfaces of the skin. This  to-do will result to accumulation of skin cell   s to thick flakes which may look like fish scales, adhering themselves to the body.Acquired ichthyosis often appears as a manifestation of systemic disease, described in association with malignancies, drugs, endocrine and metabolic disease, HIV, infection, and autoimmune conditions It is usually is associated with people who have Hodgkins disease but it is also occurs in people with mycosis fungoides, other malignant sarcomas, Kaposis sarcoma and visceral carcinomas. It can occur in people suffering from leprosy, AIDS, tuberculosis, and typhoid fever.With such a rate of variation between the severity of various ichthyotic conditions and the degrees of variance  indoors the conditions themselves, it is impossible to place a single prognosis or plan of treatment on ichthyosis or any ichthyotic condition in particular. In actuality since ichthyosis is such a rare disorder with such a low rate of  relative incidence with the most common, ichthyosis vulgaris at 1 in 250, X-linked at 1 in    6,000 in males and ichthyoses in their  entireness at about 1 in 250,000, more often the not, it must be evaluated and treated on a case to case basis.However despite the tremendous margin of difference between conditions the basic objective remains the same, to aid the skin in retaining moisture, shedding, and in the promotion of a softer, suppler, more  conciliative skin surface. While no cure for ichthyosis exists the current treatment options for an ichthyotic patient are topical therapy, bathing, and  robotlike scale removal, along with psychosocial support for patient and family via patient organizations.Topical therapy focuses on the regeneration of the epidermal  restriction by water binding, Transepidermal Water Loss (TEWL) reduction and reformation of the lipid barrier or anti-inflammation with the  fixity use of ointments containing lipids, keratolytic, and/or hydrating substances. Therapeutic bathing seeks to loosen scales and residual medications in addition to hydrati   ng the skin with  flat baths up to twice a day with sodium bicarbonate, wheat, corn, or rice starch, during which scales and hyperkeratoses are mechanically  withdraw using repetitive gentle rubbing using microfiber household towels, pumice stones, or special silk gloves.typically the prognosis for very poor for infants born with the most severe ichthyoses, such as epidermolytic hyperkeratosis and harlequin ichthyosis where the child is born with severe blistering and huge, thick scales punctuated by deep fissures, if the infant doesnt die within the first few days of life from dehydration, the next several weeks leave the neonate extremely  attached to infection, sepsis and death.While if an infant does survive into its first few months of life, the chances of survival are relatively good, as with the other degrees of ichthyosis, once the conditions more life-threatening symptoms have been stabilized, the survivability rate is much better and work can  find to be done on improving    the quality of life.In cases such as these tremendous advancements have been made with the introduction of specialized intensive care units and a recent evolution of Retinoid medications, along with the various creams, salves and ointments aimed at moisturizing the skin and aiding the skin in shedding. Of the topical lotions, ointments and creams themselves, advancements have been made in the use of nanotechnology, in order to more finely mill the medications in the salves into nano-sized particles, greatly increasing the absorption into the skin and productiveness of topical treatment.Since ichthyosis is a genetic disorder the search for an absolute cure has been largely limited to gene therapy and stem cell research, the latter of which is hindered by legal and ethical debate, while the former has been extremely  restricted since a string of gene therapy related deaths in 2002, since which gene therapy has been largely limited to severe autoimmune diseases with fatal prognosises.    So the bulk of ichthyosis-related research has been directed toward creating new products to alleviate the symptoms and provide a  high standard of living.However in 2009, a major victory was won for the sufferers and researcher of inherited ichthyosis, when the  outcome of the First Ichthyosis Consensus Conference held in Soreze, France, on January 23 and 24, 2009, where subcommittees on different issues proposed terminology that was debated until consensus was reached. The classification  vagabond started two years prior, at the First World Conference on Ichthyosis in 2007. And after its completion, allowed for a universal system of taxonomy was adopted for the nomenclature involving inherited ichthyosis.Works Citedhttp//emedicine.medscape.com/article/1198130-overview
