The influence of stereotypes on decisions to shoot

EUROPEAN JOURNAL OF SOCIAL PSYCHOLOGY, Issue 6 2007
Joshua Correll
Using a videogame to simulate encounters with potentially hostile targets, three studies tested a model in which racial bias in shoot/don't-shoot decisions reflects accessibility of the stereotype linking Blacks to danger. Study 1 experimentally manipulated the race-danger association by asking participants to read newspaper stories about Black (vs. White) criminals. As predicted, exposure to stories concerning Black criminals increased bias in the decision to shoot. Studies 2 and 3 manipulated the number of White and Black targets with and without guns in the context of the videogame itself. As predicted, frequent presentation of stereotypic (vs. counterstereotypic) targets exacerbated bias (Study 2) and,consistent with our process account,rendered stereotypes more accessible (Study 3).

Metastatic Crohn's disease: a review

JOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 9 2008
I Palamaras
Abstract Metastatic Crohn's disease (MCD) indicates the presence of non-caseating granuloma of the skin at sites separated from the gastrointestinal tract by normal tissue and is the least common dermatologic manifestation of CD. In adults, MCD usually appears after the initial diagnosis of CD in 70% of cases, whereas in children, it appears at the same time as CD in almost half of the cases. The most frequent skin lesions in adults are nodules, plaques with or without ulceration on the extremities and ulcers on the genitals. In children, genital swelling with or without erythema is the most frequent presentation of MCD. Simultaneous presence of perianal CD affects more females (60%) and particularly children. Associated gastrointestinal symptoms are present in one third of the cases in adults and in half of the cases in children. Treatment is often unsatisfactory. Randomised controlled trials are lacking. Various chemotherapeutic agents have been used such as oral metronidazole, topical and/or oral steroids, azathioprine, cyclosporine, sulfasalazine, tetracyclines, topical or systemic tacrolimus, infliximab alone or with methotrexate, and surgical treatment with oral zinc sulphate. MCD represents another ,great imitator'. This reviews the most relevant characteristics of this disease, in order to increase awareness and to avoid delay in diagnosis and improve management of the whole CD complex. [source]

Fijian seasonal scourge of mango tree falls

ANZ JOURNAL OF SURGERY, Issue 12 2009

Abstract Background:, Mango tree falls are a frequent presentation at any health facility in the South Pacific. This study aims to identify (i) the number of admissions because of falls from mango trees; (ii) epidemiology; (iii) seasonal trend; (iv) injury profile; and (v) hospital care provided. Methods:, Retrospective case review on all mango tree falls related injuries resulting in admissions at the Lautoka Hospital, Fiji during a 1-year period (2007). Patient records were analysed to identify specific injury patterns such as upper/lower limb fractures, spinal cord injury and head injury, caused by mango tree falls. Results:, Thirty-nine cases were identified. Eighty-two percent (n= 32) of the falls occurred in the mango season (June,November). Seventy-two percent (n= 28) of the patients were males and 28% (n= 11) were females. Seventy-six percent were aged 5,13 and only 21% were adults. Also, 77% (n= 30) of the patients were ethnic Fijians and 23% (n= 9) were Fijian-Indians. Sixty-four percent (n= 25) had closed fractures and 17% (n= 7) had open fractures. Fifty-six percent (n= 22) of the fractures were of the fore arm. There were two cases of spinal cord injury, four cases of head injury, one ICU admission and one death. Average hospital stay was 7.56 days. Conclusion:, All these injuries were recreational and the majority in the urban setting. They were all avoidable. [source]

Cataract, loss of visual acuity, infection after trabeculectomy

ACTA OPHTHALMOLOGICA, Issue 2009
AM BRON
Purpose Trabeculectomy is the most popular surgery for glaucoma, however some complications may impair the success of the procedure. Moreover without impacting the overall efficacy of trabeculectomy, the quality of life of the patients could be affected in a certain number of cases. Methods In this session we will give some tips to prevent and to treat these complications. Results Cataract is frequent after trabeculectomy and is mainly related to postoperative hypotony. In most recent clinical studies cataract has been shown to occur in half of the eyes 3 years after trabeculectomy. This has led H Jampel to write a provocative editorial; Trabeculectomy: more effective at causing cataract surgery than lowering intraocular pressure (Ophthalmology 2009;116:173-174). In advanced cases, severe sight-threatening complications such as the wipe-out syndrome, even uncommon may definitely lead the patient to blindness. The two more frequent presentations of infection after trabeculectomy are blebitis and endophthalmitis. Both can occur several years after trabeculectomy and Streptococci which are frequently found are devastating strains. Antimetabolites greatly increase the prevalence of endophthalmitis after trabeculectomy. Other less severe complications such as bleb dysesthesia may alter the quality of life of the patients. Conclusion The information of the patients and the quality of the follow-up are of paramount importance when a trabeculectomy is considered. [source]
