Crusted Scabies in Remote Aboriginal Communities2014 EDITIONChronic disease case management of crusted scabies to break the cycle of recurrences and transmission Document prepared by: Program design and people empowerment CRUSTED SCABIES AND ITS SIGNIFICANCE A severe form of scabies, caused when an individual's immune system is not able to control mite Hyper-infection develops, often with up to a million or more scabies mites. This is compared with 5-10 mites in simple scabies.
Abnormally thick layers of keratinised cells in the stratum corneum, mixed with thousands of scabies mites, eggs, mite faeces and shed skin. Hyperkeratosis can be localised or widespread. In scabies endemic areas, crusted scabies must be treated as a chronic condition.
What is its significance? Individuals with crusted scabies experience lower life expectancy, frequent hospitalisations and develop secondary bacterial complications.
Household contacts of unmanaged crusted scabies have high risk of recurrent scabies, Strep A skin sores, poor sleep, disruption of school and work. Strep A skin sores are associated with chronic heart and renal disease.
Crusted scabies is highly infectious and causes outbreaks of scabies. Effective management is essential to the control of scabies in communities.

Misdiagnosis results in unnecessary and expensive treatment and puts the patient on an unnecessary chronic condition management plan. Time spent properly confirming diagnoses will save time and resources in the future.

A Identify / confirm clinical appearance Characteristic crusted skin patches; Thickened, scaly skin patches. Often not itchy.
Often, but not always on buttocks, hands, feet, elbows, armpits Scale may have distinctive creamy colour Do not confuse with tinea, psoriasis, eczema or dermatitis as it may look similar.
Specialist diagnosis recommended; The diagnosis can be difficult. Always consult Infectious Disease Team via switch at Royal Darwin Hospital 08 8922 8888 or Alice Springs Hospital 08 8951 7777.
As underlying immune deficiency can be cause of the disease further testing is warranted. Discuss with infectious disease specialist.
Staff and carers should practice infection control procedures including wearing disposable gloves.
Take care not to come in contact with scabies-containing fomites such as bedding or seating.
If you think you have been exposed to scabies during the course of your work you may wish to apply a scabicide cream preventatively (e.g. benzyl benzoate) to exposed areas.

1. DIAGNOSIS MANAGING CRUSTED SCABIES IN REMOTE ABORIGINAL COMMUNITIES 2014 EDITION 6 1. Identify an area of suspected crusting (thickened, scaly skin).
2. Gently use the sharp side of a sterile scalpel held at a 90º angle to scrape loose flakes of skin into a sterile urine collection jar. If true crusting is present skin should be easily collected.
Collect loose flakes of skin from areas of Collection technique suspected crusting 3. Don't rush the process. The more skin collected the greater the chance of confirming the diagnosis. A few pieces of skin may be sufficient, but collect as much skin as possible.
4. If skin is not readily falling into the jar crusted scabies is less likely.
5. Do not cut or injure the skin. Infection and sepsis is a real risk in these patients.
6. Send collected sample to lab for testing. Make sure to request testing of scabies mites.
7. Absence of mites from skin scrapings does not rule out the possibility of crusted scabies. If results are positive this greatly increases the likelihood of crusted scabies.

While it can be frustrating, do not label the patient or family non- compliant. The family has to be part of the treatment team.
2. PATIENT TREATMENT MANAGING CRUSTED SCABIES IN REMOTE ABORIGINAL COMMUNITIES 2014 EDITION 12 Ideally all patients should be admitted to hospital for treatment (esp. grades 2-3). This is due to risk of sepsis, re-infection from fomites and contacts and infection control. For first diagnosis hospitalisation is especially important as possible underlying immune deficiency needs to be investigated. For community based treatment of crusted scabies at home it is very important that the topical therapy is supervised by the health staff-preferably all doses but especially the first.
Community based treatment: 1. Give ivermectin single dose on days 0, 1, 7. Give with food or milk for better absorption. (N.B. Longer treatment needed for Grade 2-3. Contact Infectious Disease Team at Royal Darwin Hospital 08 8922 8888 or Alice Springs Hospital 08 8951 7777).
2. Give topical agents (critical part of treatment): Lactic acid and urea cream (e.g. Calmurid), every second day to soften skin. Don't use on same day as scabies cream. Applying lactic acid/urea and the next day a warm soaking bath/shower and scrubbing with a sponge is critical for removal of crusts. Benzyl benzoate 5% with/without tea tree oil OR permethrin every second day for first week. Dilute benzyl benzoate for children under 12. THEN twice a week until well. Put on after soaking bath/shower.

3. HOUSEHOLD TREATMENT MANAGING CRUSTED SCABIES IN REMOTE ABORIGINAL COMMUNITIES 2014 EDITION 15 Making sure everyone joins in The application of creams is inconvenient but ensuring all household members use the treatment is critical to the success. Make it a fun occasion and consider the following tips to get everyone involved.
Strategies for success Take time to get the support and interest of a senior household member. Explain benefits in terms of reduced sores and improved sleep. It is important to be flexible on the timing. Select a day and time when most of household will be present (e.g. after school in the afternoon).
Involve senior members of household in helping others apply creams.
Start the application of creams during the home visit. Start by involving mothers to apply creams on children.
Often young children will be frightened. Start with an older person, apply on arms of mothers, staff to get things started. After initial reluctance a tipping point is reached where everyone joins in. The trick is to stay positive and keep going until you reach this point.
Encourage older teens and adults to help each other with application. Highlight wearing creams as a sign of their support for household health and wellbeing.
Ensure privacy and appropriate consent before applying creams. Parents should apply creams on children and be present at all times.
Be discrete. The family may not want the whole community to know they are being treated for scabies.
Screen children and record names of children with scabies. Refer other conditions to health centre If the family agrees, organise a clean-up for the house. If possible supply cleaning products and equipment.
Encourage household to put bedding, clothes and mattresses in sun.
If it is requested by the family, set insecticide bombs in the house (available over-the-counter in stores). Ensure families read and understand instructions.
Avoid other health promotion or clinical activities while doing a mini skin day.
3. HOUSEHOLD TREATMENT MANAGING CRUSTED SCABIES IN REMOTE ABORIGINAL COMMUNITIES 2014 EDITION 16 Maintenance plan to prevent recurrences once patient and family are treated and free of scabies.
4. CHRONIC CARE PLAN MANAGING CRUSTED SCABIES IN REMOTE ABORIGINAL COMMUNITIES 2014 EDITION 17 Ensure a regular supply of creams to patient (e.g. 2 benzyl benzoate, 4 lactic acid/urea (Calmurid) and 4 moisturisers per month) to patient. Breakdown in supply of these creams to patient are a common cause of recurrence.
Only benzyl benzoate should be used for regular preventative treatment (regular use of permethrin or ivermectin can lead to development of resistance).
Patients should not share a bed and should have a hospital grade mattress which can be easily cleaned Patients at high risk of re-exposure to scabies are those living in a house with many occupants especially An intensive phase of clinic involvement is important to show the patient and household the benefit of adherence to the chronic care plan (e.g sleep).
The patient's seniority in the house is critical. More support is needed for patients without seniority.
* The ultimate goal should be self-care and management with clinics supplying creams and skin checks.
4. CHRONIC CARE PLAN MANAGING CRUSTED SCABIES IN REMOTE ABORIGINAL COMMUNITIES 2014 EDITION 18 Ongoing management Ongoing management is required after a full treatment of the crusted scabies as per guidelines and where an excellent response has occured with no evidence of residual active scabies.

4. CHRONIC CARE PLAN MANAGING CRUSTED SCABIES IN REMOTE ABORIGINAL COMMUNITIES 2014 EDITION 19 Recurrences are to be expected Detect, treat early and don't get disillusioned.
Problem-solve with the family as they are part of the treatment team.
Common causes of recurrence include: - Not treating all contacts. - Failure to apply creams to hard to reach areas, especially buttocks. - Running out of supplies of preventative creams. - Visitors with scabies re-introduce disease to household.
Offer more scabies cream and promote their use with all household contacts.
Consider repeating household treatment and expanding it to include closely related households that could be source of re-infection.
If scabies persists speak to the One Disease team for program guidance. At this stage it is more important than ever not to blame the family. In these cases there is normally something else going on and if that can be resolved the scabies will often be fixed by the family themselves. This may just take time and patience.
If many household have scabies consider a Healthy Skin Day. See CDC Healthy Skin Program Guidelines and/or call One Disease for advice.

LA NULIDAD COMO MEDIO DE CONTROL EN LA LEY 1.437 DE 2011 ¿UNA NUEVA INCONSTITUCIONALIDAD? DR. NESTOR RAUL SANCHEZ BAPTISTA Fecha de recepción: 27 de Abril de 2011 – Fecha de aceptación: 1 de junio de 2011 El artículo 137 de la Ley 1.437 de 2011 establece que la nulidad, como medio de control judicial contra los actos administrativos, procede contra los de carácter general y, excepcionalmente, contra ciertos y determinados actos de naturaleza particular y concreta, plasmando así en la ley lo que venía sosteniéndose en la jurisprudencia del Consejo de Estado colombiano, y modificando el postulado general establecido en el artículo 84 del CCA, según el cual la nulidad procede contra todos los actos administrativos definitivos, generales o particulares. Tal concepción jurisprudencial fue considerada contraria a la Constitución Política por la Corte Constitucional con la sentencia C-426 de 2002, en la medida en que era restrictiva del derecho de acceso a la justicia al contener limitaciones no establecidas en la ley. Ahora que fue incorporada a la ley surge el interrogante de si tal inconstitucionalidad fue superada, dado que en los considerandos de aquella se enfatizó en la estrecha relación existente entre la acción de nulidad y el principio de legalidad, para la salvaguarda de la integridad del ordenamiento jurídico sin limitaciones que se consideran constitucionalmente ilegítimas, desproporcionadas e irrazonables. Palabras Claves: Nulidad de actos administrativos, medios de control, guarda de la integridad del ordenamiento, derecho de acceso a la justicia, restricciones legales, inconstitucionalidad. Abstract
