Necrotizing fasciitis: delay in diagnosis results in loss of limb

INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 10 2006
Rajat Varma MD
A 58-year-old man presented to the Emergency Room with a 1-day history of severe pain in the left lower extremity preceded by several days of redness and swelling. He denied any history of trauma. He also denied any systemic symptoms including fever and chills. His past medical history was significant for diabetes, hypertension, deep vein thrombosis, and Evans' syndrome, an autoimmune hemolytic anemia and thrombocytopenia, for which he was taking oral prednisone. Physical examination revealed a warm, tender, weeping, edematous, discolored left lower extremity. From the medial aspect of the ankle up to the calf, there was an indurated, dusky, violaceous plaque with focal areas of ulceration (Fig. 1). Figure 1. Grossly edematous lower extremity with well-demarcated, dusky, violaceous plaque with focal ulceration Laboratory data revealed a white blood cell count of 6.7 × 103/mm3[normal range, (4.5,10.8) × 103/mm3], hemoglobin of 11.5 g/dL (13.5,17.5 g/dL), and platelets of 119 × 103/mm3[(140,440) × 103/mm3]. Serum electrolytes were within normal limits. An ultrasound was negative for a deep vein thrombosis. After the initial evaluation, the Emergency Room physician consulted the orthopedic and dermatology services. Orthopedics did not detect compartment syndrome and did not pursue surgical intervention. Dermatology recommended a biopsy and urgent vascular surgery consultation to rule out embolic or thrombotic phenomena. Despite these recommendations, the patient was diagnosed with "cellulitis" and admitted to the medicine ward for intravenous nafcillin. Over the next 36 h, the "cellulitis" had advanced proximally to his inguinal region. His mental status also declined, and he showed signs of septic shock, including hypotension, tachycardia, and tachypnea. Vascular surgery was immediately consulted, and the patient underwent emergency surgical debridement. The diagnosis of necrotizing fasciitis was then made. Tissue pathology revealed full-thickness necrosis through the epidermis with subepidermal splitting. Dermal edema was also present with a diffuse neutrophilic infiltrate (Fig. 2). This infiltrate extended through the fat into the subcutaneous tissue and fascia. Tissue cultures sent at the time of surgery grew Escherichia coli. Initial blood cultures also came back positive for E. coli. Anaerobic cultures remained negative. Figure 2. Necrotic epidermis with subepidermal splitting.

Corticosteroid phobia and other confounders in the treatment of childhood atopic dermatitis explored using parent focus groups

AUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 3 2010
Saxon D Smith
ABSTRACT Background/Objectives:, Anxieties associated with corticosteroid treatment and preference for ,safer natural therapy' are common in parents of children with atopic dermatitis. We used focus groups to explore the source of these attitudes. Methods:, The study involved 16 parents. Parents expressed difficulties with living with and treating atopic dermatitis which were categorized into themes using qualitative data analysis software. Results:, Themes identified include: emotional impact of atopic dermatitis; difficulty in accepting ,control' verses ,cure'; topical corticosteroid negative perceptions; anxiety and confusion with treatment; preference for ,natural' therapy; and attitude-changing positive experiences. Conclusions:, Our findings illustrate the emotional impact of atopic dermatitis and the frustration with the lack of potential cure. ,Corticosteroid phobia' was universal among parents in our cohort and is a fear generated by doctors, pharmacists, close acquaintances and information from the internet. Participants expressed high levels of parental guilt linked to a desire for an eradicable ,cause' for atopic dermatitis, despite intellectually understanding this is a genetically determined condition. Parents were willing to change attitudes with accurate information from perceived reliable sources, positive hospitalization experiences and a relationship with a trusted dermatologist. Parents' suggestions to improve confidence included the provision of readily available information and better access to doctor- and nurse-led paediatric dermatology services. [source]

Teledermatology in the U.K.: lessons in service innovation

BRITISH JOURNAL OF DERMATOLOGY, Issue 3 2007
T.L. Finch
Summary Background, Teledermatology has the potential to revolutionize the delivery of dermatology services by facilitating access to specialist services at a distance. In the U.K. over the previous decade there have been numerous attempts at introducing and using teledermatology; however, the development of teledermatology as routine service provision remains limited. Objectives, To identify factors that promote successful use of teledermatology as a part of routine service provision. Methods, A longitudinal qualitative study of teledermatology, drawing on data from in-depth semistructured interviews; observations of systems in practice; and public meetings. Data were analysed collectively by the research team using established qualitative analytical techniques to identify key thematic categories. The sample consisted of teledermatology services within the U.K. (n = 12) studied over 8 years (1997,2005). Individual participants (n = 68 interviews) were consultant dermatologists, researchers, teledermatology nurses, administrators, patient advocates, general practitioners and technologists. Results, The analysis compared services that did or did not become part of routine healthcare practice to identify features that supported the normalization of teledermatology. Requirements for using and integrating teledermatology into practice included: political support; perceived benefit and relative commitment that outweighs effort; pragmatic approaches to proving efficacy and safety; perception of risk as being ,manageable' on the basis of professional judgement; high levels of flexibility in practice (in terms of individuals, technology and organization); and reconceptualizing professional roles. Conclusions, Successful implementation of teledermatology as a routine service requires greater understanding of and attention to the interplay between social and technical aspects of teledermatology, and how this is accommodated both by healthcare professionals and the organizations in which they work.

Preferences for aspects of a dermatology consultation

BRITISH JOURNAL OF DERMATOLOGY, Issue 2 2006
J. Coast
Summary Background, General practitioners with special interests (GPSIs) are increasingly being used to provide dermatology services in the U.K. Little is known about U.K. dermatology patient attitudes to proposed variations in secondary care service delivery or the values they attach to aspects of the care they receive. Objectives, To quantify preferences for different attributes of care within dermatology secondary care services. Methods, Attributes of care that are important to dermatology patients were derived using in-depth qualitative interviews with 19 patients at different points in the care pathway. A discrete choice experiment using ,best,worst scaling' was sent by post to 119 patients referred to secondary care dermatology services and suitable for GPSI care who had agreed to participate in research. Results, Four attributes were derived from the qualitative work: waiting, expertise, thorough care and convenience. For the discrete choice experiment, 99 patients returned questionnaires, 93 of which contained sufficient data for analysis. All attributes were found to be quantitatively important. The attribute of greatest importance was expertise of the doctor, while waiting time was of least importance. Respondents were willing to wait longer than the current 3 months maximum to receive care that was thorough, 2·1 months to see a team led by an expert and 1·3 months to attend a consultation that is easy to get to. Conclusions, Although the need to reduce outpatient waiting times is a key policy driver behind the expansion of GPSI services, this does not appear to be the most important issue for patients. The thoroughness with which the consultation is provided and the expertise of the clinician seen are higher priorities. [source]
