She had graduated from Boston College with a degree in psychology, married at twenty-five, and had two children, a son and a daughter. She and her family settled in a town on Massachusetts’ southern shore. She worked for thirteen years in health care, becoming the director of a residence program for men who’d suffered severe head injuries. But she and her husband began fighting. There were betrayals. By the time she was thirty-two, her marriage had disintegrated. In the divorce, she lost possession of their home, and, amid her financial and psychological struggles, she saw that she was losing her children, too. Within a few years, she was drinking. She began dating someone, and they drank together. After a while, he brought some drugs home, and she tried them. The drugs got harder. Eventually, they were doing heroin, which turned out to be readily available from a street dealer a block away from her apartment. One day, she went to see a doctor because she wasn’t feeling well, and learned that she had contracted H.I.V. from a contaminated needle. She had to leave her job. She lost visiting rights with her children. And she developed complications from the H.I.V., including shingles, which caused painful, blistering sores across her scalp and forehead. -

Pruritus: Scratching the Surface
Pruritus: Scratching the surface Iris Ale, MD Director Allergy Unit, University Hospital Professor of Dermatology Republic University, Uruguay Member of the ICDRG ITCH • defined as an “unpleasant sensation of the skin leading to the desire to scratch” -- Samuel Hafenreffer (1660) • The definition offered by the German physician Samuel Hafenreffer in 1660 has yet to be improved upon. • However, it turns out that itch is, indeed, inseparable from the desire to scratch. Savin JA. How should we define itching? J Am Acad Dermatol. 1998;39(2 Pt 1):268-9. Pruritus • “Scratching is one of nature’s sweetest gratifications, and the one nearest to hand….” -- Michel de Montaigne (1553) “…..But repentance follows too annoyingly close at its heels.” The Essays of Montaigne Itch has been ranked, by scientific and artistic observers alike, among the most distressing physical sensations one can experience: In Dante’s Inferno, falsifiers were punished by “the burning rage / of fierce itching that nothing could relieve” Pruritus and body defence • Pruritus fulfils an essential part of the innate defence mechanism of the body. • Next to pain, itch may serve as an alarm system to remove possibly damaging or harming substances from the skin. • Itch, and the accompanying scratch reflex, evolved in order to protect us from such dangers as malaria, yellow fever, and dengue, transmitted by mosquitoes, typhus-bearing lice, plague-bearing fleas • However, chronic itch lost this function. Chronic Pruritus • Chronic pruritus is a common and distressing symptom, that is associated with a variety of skin conditions and systemic diseases • It usually has a dramatic impact on the quality of life of the affected individuals Chronic Pruritus • Despite being the major symptom associated with skin disease, our understanding of the pathogenesis of most types of itch is limited, and current therapies are often inadequate. -

Urticaria and Angioedema
Skin tests may be performed to determine the substance that you are allergic to. Routine blood tests are done to determine if a systemic illness is present. Urticaria and Treatment for Urticaria and Angioedema Angioedema • The best treatment for hives and angioedema is to identify and remove the trigger, but this is often a hard task. • Antihistamines block the effect of histamine, and can reduce itching and rash in most cases. Antihistamines may be needed for as long as the urticaria persists. Reports of serious side effects of antihistamines are very rare. Allergy Centre • A low histamine diet can help to reduce exogenous histamine derived from foods, which helps in some cases. To find out more about a low histamine diet, please contact our dietitian. 過敏病科中心 • Oral corticosteroids may be prescribed. • For a severe hives or angioedema outbreak, an injection of adrenaline or a steroid medication may be needed. • Other immunosuppressant such as cyclosporin may be beneficial in severe cases for long term control.

Urticaria and Angioedema
Urticaria and Angioedema This guideline, developed by Robbie Pesek, MD and Allison Burbank, MD, in collaboration with the ANGELS team, on July 23, 2013, is a significantly revised version of the guideline originally developed by Jeremy Bufford, MD. Last reviewed by Robbie Pesek, MD September 14, 2016. Key Points Urticaria and angioedema are common problems and can be caused by both allergic and non- allergic mechanisms. Prompt diagnosis of hereditary angioedema (HAE) is important to prevent morbidity and mortality. Several new therapeutic options are now available. Patients with urticaria and/or angioedema should be referred to an allergist/immunologist for symptoms that are difficult to control, suspicion of HAE, or to rule out suspected allergic triggers. Definition, Assessment, and Diagnosis Definitions Urticaria is a superficial skin reaction consisting of erythematous, raised, blanching, well- circumscribed or confluent pruritic, edematous wheals, often with reflex erythema.1-3 Urticarial lesions are typically pruritic, and wax/wane with resolution of individual lesions within 24 hours. Angioedema is localized swelling of deep dermal, subcutaneous, or submucosal tissue resulting from similar vascular changes that contribute to urticaria.1,2 Angioedema may be pruritic and/or painful and can last for 2-3 days depending on etiology.3 1 Urticaria alone occurs in 50% of patients and is associated with angioedema in 40% of patients. Isolated angioedema occurs in 10% of patients.1,2 Hereditary angioedema (HAE) is a disorder involving defects in complement, coagulation, kinin, and fibrinolytic pathways that results in recurrent episodes of angioedema without urticaria, usually affecting the skin, upper airway, and gastrointestinal tract.4 In children, acute urticaria is more common than chronic forms. -
Pathophysiology and Treatment of Pruritus in Elderly
International Journal of Molecular Sciences Review Pathophysiology and Treatment of Pruritus in Elderly Bo Young Chung † , Ji Young Um †, Jin Cheol Kim , Seok Young Kang , Chun Wook Park and Hye One Kim * Department of Dermatology, Kangnam Sacred Heart Hospital, Hallym University, Seoul KS013, Korea; [email protected] (B.Y.C.); [email protected] (J.Y.U.); [email protected] (J.C.K.); [email protected] (S.Y.K.); [email protected] (C.W.P.) * Correspondence: [email protected] † These authors contributed equally to this work. Abstract: Pruritus is a relatively common symptom that anyone can experience at any point in their life and is more common in the elderly. Pruritus in elderly can be defined as chronic pruritus in a person over 65 years old. The pathophysiology of pruritus in elderly is still unclear, and the quality of life is reduced. Generally, itch can be clinically classified into six types: Itch caused by systemic diseases, itch caused by skin diseases, neuropathic pruritus, psychogenic pruritus, pruritus with multiple factors, and from unknown causes. Senile pruritus can be defined as a chronic pruritus of unknown origin in elderly people. Various neuronal mediators, signaling mechanisms at neuronal terminals, central and peripheral neurotransmission pathways, and neuronal sensitizations are included in the processes causing itch. A variety of therapies are used and several novel drugs are being developed to relieve itch, including systemic and topical treatments.
