TheAmerican Board of Internal Medicine Foundation's Choosing WiselyÒ campaign isa multiyear effort to encourage physician leadership in reducing harmful orinappropriate resource utilization. Via the campaign, medical societies are asked toidentify five tests or procedures commonly used in their field, the routine use of which inspecific clinical scenarios should be questioned by both physicians and patients based onthe evidence that the test or procedure is ineffective or even harmful. The AmericanAcademy of Hospice and Palliative Medicine (AAHPM) was invited, and it agreed toparticipate in the campaign. The AAHPM Choosing Wisely Task Force, with input fromthe AAHPM membership, developed the following five recommendations: 1) Don'trecommend percutaneous feeding tubes in patients with advanced dementia; instead,offer oral-assisted feeding; 2) Don't delay palliative care for a patient with serious illnesswho has physical, psychological, social, or spiritual distress because they are pursuingdisease-directed treatment; 3) Don't leave an implantable cardioverter-defibrillatoractivated when it is inconsistent with the patient/family goals of care; 4) Don'trecommend more than a single fraction of palliative radiation for an uncomplicatedpainful bone metastasis; and 5) Don't use topical lorazepam (AtivanÒ),diphenhydramine (BenadrylÒ), and haloperidol (HaldolÒ) (ABH) gel for nausea.
These recommendations and their supporting rationale should be considered byphysicians, patients, and their caregivers as they collaborate in choosing those treatments Address correspondence to: Daniel Fischberg, MD, The Queen's Medical Center, 1301 Punchbowl Accepted for publication: December 24, 2012.

Don't recommend percutaneous feeding tubes in patients with advanced dementia; instead, offer oral-assisted feeding.
In advanced dementia, studies have found that feeding tubes do not result in improved survival, prevention of aspirationpneumonia, or improved healing of pressure ulcers. Feeding tube use in such patients has actually been associated with pressureulcer development, use of physical and pharmacologic restraints, and patient distress about the tube itself. Assistance with oralfeeding is an evidence-based approach to provide nutrition for patients with advanced dementia and feeding problems; in thefinal phase of this disease, assisted feeding may focus on comfort and human interaction more than the nutritional goals.
2. Don't delay palliative care for a patient with serious illness who has physical, psychological, social, or spiritual distress because they are pursuing disease-directed treatment.
Numerous studiesdincluding randomized trialsdprovide evidence that palliative care improves pain and symptom control,improves family satisfaction with care, and reduces costs. Palliative care does not accelerate death and may prolong life inselected populations.
3. Don't leave an ICD activated when it is inconsistent with the patient/family goals of care.
In about a quarter of patients with ICDs, the defibrillator fires within weeks preceding death. For patients with advancedirreversible diseases, defibrillator shocks rarely prevent death, may be painful to patients, and are distressing to caregivers/family members. Currently, there are no formal practice protocols to address deactivation; less than 10% of hospices haveofficial policies. Advance care planning discussions should include the option of deactivating the ICD when it no longersupports the patient's 4. Don't recommend more than a single fraction of palliative radiation for an uncomplicated painful bone metastasis.
As stated in the American Society for Radiation Oncology 2011 guideline, single-fraction radiation to a previously unirradiatedperipheral bone or vertebral metastasis provides comparable pain relief and morbidity compared with multiple-fractionregimens while optimizing patient and caregiver convenience. Although it results in a higher incidence of later need forretreatment (20% vs. 8% for multiple-fraction regimens), the decreased patient burden usually outweighs any considerationsof long-term effectiveness for those with a limited life expectancy.
5. Don't use topical lorazepam (Ativan), diphenhydramine (Benadryl), and haloperidol (Haldol) (ABH) gel for nausea.
Topical drugs can be safe and effective, such as topical nonsteroidal anti-inflammatory drugs for local arthritis symptoms.
Although topical gels are commonly prescribed in hospice practice, antinausea gels have not been proven effective in anylarge, well-designed, or placebo-controlled trials. The active ingredients in ABH are not absorbed to systemic levels that couldbe effective. Only diphenhydramine (Benadryl) is absorbed via the skin and then only after several hours and erratically atsubtherapeutic levels. It is, therefore, not appropriate for ‘‘as needed'' use. The use of agents given via inappropriate routesmay delay or prevent the use of more effective inter ICD ¼ implantable cardioverter-defibrillator.

Informe Final de Evento Cisticercosis Año 2009 INSTITUTONACIONAL D Avances en el conocimiento de la enfermedad CISTICERCOSIS: SITUACION DE LA PARASITOSIS Diana Marcela Walteros Acero MD Referente Nacional de Cisticercosis Grupo Zoonosis Subdirección de Vigilancia y Control INTRODUCCIÓN La cisticercosis es una parasitosis causada por el metacestodo de la Taenia Solium, larva que tiene gran capacidad de invasión de tejidos como el musculo esquelético, Tejido Celular Subcutáneo y Musculo cardiaco. i Sin embargo la localización que genera mayores complicaciones, letalidad y secuelas es en el Sistema Nervioso Central, configurando el cuadro de Neurocisticercosis cuyas manifestaciones clínicas son variadas y dependen de la ubicación y forma de las vesículas parasitarias. En 1993 el grupo internacional de trabajo declara que la Cisticercosis es erradicable, teniendo en cuenta los siguientes criterios: el huésped definitivo es el ser humano y este a su vez es la fuente de infección del cerdo, que es el principal huésped intermediario, en el momento hay tratamiento efectivo para la infección animal y por ultimo no se han encontrado reservorios en animales silvestres. El ser humano es el único huésped definitivo natural de la tenia y el cerdo es el principal huésped intermediario, por tanto la prevalencia de la enfermedad depende de esta relación e interacción. Aunque el humano también es el huésped definitivo de la T. saginata y los bovinos los huéspedes intermediarios, ninguna de las subespecies de la T. saginata produce la infección. ii En el 2002, en Irán se reportan 2 casos de Cisticercosis cerebral y cardiaca en perros, los cuales se podrían constituir en otros huéspedes intermediarios de la enfermedad aparte de los cerdos.iii Dentro de las medidas de control de la enfermedad en los animales se han considerado, entre otras: encorralamiento para evitar el contacto de los cerdos con las larvas de la tenia, alimentación balanceada y adecuada que no incluya desperdicios ni heces humanas, desparasitación de los animales por lo menos 2 meses antes de su sacrificio, control del estado de salud y revisiones frecuentes por profesionales veterinarios, sacrificio en lugares con infraestructura adecuada y con previa verificación de ausencia de quistes en la lengua, sacrificio y desecho de los animales enfermos, refrigeración, transporte y comercialización bajo medidas de higiene y especificaciones adecuadas para la conservación de la carne y vacunación de los animales para prevenir el desarrollo de la enfermedad. Las vacunas disponibles son de diferentes características, unas incluyen el extracto crudo del parasitoiv v, otras incluyen subunidades proteicasvi vii y otras son vacunas de DNAviii ix .

COGSMachine Consciousness: A Design Procedure.Abstract: Whether anyone likes it or not, there is something out there that goes under the heading of ‘machine consciousness' or ‘models of consciousness'. It leads to gatherings of people who come from different backgrounds, some from AI and some from computer modelling of the brain. I fall into the second group and will talk of possible contributions that understanding brain mechanisms through digital models might make to the question: is it possible to build a conscious machine? I shall give a brief description of the digital methodology and then suggest that five major, personally felt attributes are fundamental: perception, imagination, attention, prediction and emotion. These are due to interlocking mechanisms in the brain which might serve as design models for a conscious machine. If time permits, this will be examined against Chalmers' philosophical objections to the idea of a conscious machine.
