Scabies outbreaks in ten care homes for elderly people: a prospective study of clinical features, epidemiology, and treatment outcomes

Background Scabies outbreaks in residential and nursing care homes for elderly people are common, subject to diagnostic delay, and hard to control. We studied clinical features, epidemiology, and outcomes of outbreaks in the UK between 2014 and 2015. Methods We did a prospective observational study in residential care homes for elderly people in southeast England that reported scabies outbreaks to Public Health England health protection teams. An outbreak was defined as two or more cases of scabies (in either residents or staff) at a single care home. All patients who provided informed consent were included; patients with dementia were included if a personal or nominated consultee (ie, a family member or nominated staff member) endorsed participation. Dermatology-trained physicians examined residents at initial clinical visits, which were followed by two mass treatments with topical scabicide as per local health protection team guidance. Follow-up clinical visits were held 6 weeks after initial visits. Scabies was diagnosed through pre-defined case definitions as definite, probable, or possible with dermatoscopy and microscopy as appropriate. Findings 230 residents were examined in ten outbreaks between Jan 23, 2014, and April 13, 2015. Median age was 86·9 years (IQR 81·5–92·3), 174 (76%) were female, and 157 (68%) had dementia. 61 (27%) residents were diagnosed with definite, probable, or possible scabies, of whom three had crusted scabies. Physical signs differed substantially from classic presentations. 31 (51%) of the 61 people diagnosed with scabies were asymptomatic, and only 25 (41%) had burrows. Mites were visualised with dermatoscopy in seven (11%) patients, and further confirmed by microscopy in three (5%). 35 (57%) cases had signs of scabies only on areas of the body that would normally be covered. Dementia was the only risk factor for a scabies diagnosis that we identified (odds ratio 2·37 [95% CI 1·38–4·07]). At clinical follow-up, 50 people who were initially diagnosed with scabies were examined. No new cases of scabies were detected, but infestation persisted in ten people. Interpretation Clinical presentation of scabies in elderly residents of care homes differs from classic descriptions familiar to clinicians. This difference probably contributes to delayed recognition and suboptimal management in this vulnerable group. Dermatoscopy and microscopy were of little value. Health-care workers should be aware of the different presentation of scabies in elderly people, and should do thorough examinations, particularly in people with dementia.

A prospective study of scabies outbreaks in ten residential care facilities for the elderly in South-East England, 2014-15

Introduction Scabies is a significant problem in UK elderly residential care facilities (RCF); outbreaks are common and difficult to control. Clinical presentations in the elderly are poorly understood. We studied scabies outbreaks in RCFs to investigate the clinical signs and risk factors in this population. Methods We visited RCFs with suspected scabies outbreaks. We examined residents, performed dermoscopy and skin scrapings, and classified their scabies diagnosis as definite (mite visualised)/probable (compatible symptoms, mite not visualised)/possible (non-specific rash + contact with case) or non-scabies. All residents were treated twice with a topical scabicide, and a second visit conducted. Results We examined 230 residents at 10 RCFs between 03/02/2014-11/02/2015. Their median age was 87 years, 76% were female, and 68% had dementia. 61 (27%) had scabies (13% definite); 41% with burrows, 51% had not reported symptoms. Dermoscopy identified the mite in 7 cases (11.5%), skin scrapings in 3. We diagnosed a median 6 cases/RCF. Dementia was strongly associated with scabies (OR=2.4, 95% CI 1.4-4.1). No new cases were identified at the second visit (median interval 44 days), 10 cases still had scabies (2 probable, 8 possible). Discussion Scabies diagnosis is difficult in this population; half of cases were asymptomatic, and dermoscopy and skin scrapings were of limited diagnostic value. Our study is the first to confirm that dementia is a risk factor for scabies in this group. Careful examination of elderly residents of RCFs with suspected scabies outbreaks is important, particularly those with dementia, as they may have no obvious clinical signs

Der Liebescode : zur poetischen Korrespondenz Bertolt Brechts und Margarete Steffins

In the present study, the sonnets Margarete Steffin and Bertolt Brecht wrote each other will be examined both in regard to the form of the sonnet as well as the tradition with which this form is associated. A second point of consideration, which stands to a certain extent in conflict with the first, is the dialogue which these sonnets constitute. This dialogue provided Steffin and Brecht the forum and opportunity to be equal partners, contrary to their real-life situations, where equality between the two did not exist. This forum allowed them to witness and experience each other simultaneously both as subjects and objects both in terms of longing and desire, as in poetic discourse, enabling them to mutually influence each other. And as the sonnets show, this influence did in fact occur regarding their different ideas, attitudes and needs in their relationship to each other
