Skin allergy - Research Paper Example Urticaria or hives is an itchy rash, due to hypersensitive reaction by the skin (Linscott, Emedicine). The condition may be acute or chronic and there are several variants to this condition. Itching can occur without any rash and may be due to some disease related to that part of the skin. Even some medications can cause itching. As far as atopic dermatitis is concerned, the cause is actually unknown. However, several researchers have attributed genetic and environmental mechanisms to the development of atopic dermatitis. Factors which contribute to the development of atopic dermatitis are infection, poor hygiene, extremes of climate, food antigens and aeroallergens (Kraffchik, Emedicine). Several chemicals sensitize the skin and cause allergic contact dermatitis. Some of the important chemicals are poison ivy, Nickel, rubber gloves, p-phenylenediamine, dyes, formaldehyde, wash and wear chemicals and preservatives (Hogan, Emedicine). In urticaria, the cause is unknown most of the times. However, ingections, foods, stress, drugs, exposure to certain temperatures and climates and exposure to latex can trigger the development of the condition (Linscott Emedicine). In atopic dermatitis, the pathophysiology is poorly understood. However, it has been thought that sensitization of IgE and epithelial barrier disturbance secondary to some kind of immune dysfunction is the cause for the allergic rashes. Another important defect attributed to this condition is defective epithelial cells contributing to defective barrier mechanism (Kraffchik, Emedicine). The main immune disturbance is imbalance in the T-lymphocytes with TH2 cells dominating the system and causing release of cytokines like granulocyte macrophage stimulating factor and interleukins 4,5, 12 and 13. All these amount to an increase in IgE levels and fall in interferon gamma levels. In those with chronic

Casd Briefing - Essay Example President Nixon refused to comply, arguing executive privilege. At issue: Does the President’s inherent right to safeguard certain information make him entirely immune to judicial review? President Nixon (through his counsel, James St. Clair) argued that the special prosecutor, functioning as an employee of the Department of Justice, made any request for White House audiotapes an internal matter to be resolved within the Executive Branch. In sum, the Judicial Branch was overstepping its Constitutional authority by intervening in the matter. Special prosecutor Leon Jaworski argued that the audiotapes in question almost certainly contained direct evidence of a criminal conspiracy, to wit, to commit obstruction of justice. Procedural history: Special prosecutor Jaworski secured a subpoena in Federal District Court (Judge John Sirica, presiding) requiring White House compliance with demands to surrender certain audiotapes, in April 1974, requiring the White House to surrender the tapes no later than May 31. The White House refused to comply. Both Jaworski and St. Clair (the President’s counsel) concurred in requesting the Supreme Court hear the appeal from the Sirica decision—‘certiorari before judgment,’ a procedure allowing the matter to proceed directly to the Supreme Court without an intervening hearing and decision rendered by the Court of Appeals for the DC Circuit—which motion was granted. The Court heard arguments on July 8 and delivered its unanimous opinion on July 24, 1974. 3 The law: There was not specific statute at issue. However, certain language in the Constitution appears relevant. That document makes no reference to executive privilege, although it privileges Members of Congress in matters relating to debate (Art. I, sec. 6). Article II (the Presidency), provides, inter alia, that â€Å"The
