ABSTRACT Introducción: Los antipsicóticos atípicos (AA) quetiapina, olanzapina y ziprasidona se utilizan para el tratamiento de trastornos conductuales asociados a demencia. Esta indicación no fi gura en su fi cha técnica. El objetivo de este estudio es analizar la relación de estos tratamientos con la mortalidad y otros factores. Método: Estudio retrospectivo desde marzo de 2005 hasta julio de 2007 de los tratamientos de AA solicitados como uso compasivo. Se registraron datos de mortalidad, edad, antecedentes de cardiopatía o de enfermedad cerebrovascular (ECV), duración y tratamiento por paciente. Resultados: Los pacientes estudiados fueron 289. La mortalidad fue del 31,1 %. Se constató mayor mortalidad en los pacientes con antecedentes de enfermedad cardiovascular y en los que usaron olanzapina. La quetiapina fue el antipsicótico más prescrito. Conclusiones: La utilización de AA en ancianos puede tener riesgos que superen los benefi cios. Cuando se prescriben en pacientes de riesgo deben considerarse las alertas sobre su seguridad y la individualidad de cada paciente. De acuerdo con nuestros datos, la olanzapina parece entrañar un mayor riesgo que la quetiapina y la ziprasidona.

    ABSTRACT: INTRODUCTION: Some treatments are inappropriate for patients with cognitive decline. We analyse their use in 500 patients and present a literature review. DEVELOPMENT: Benzodiazepines produce dependence, and reduce attention, memory, and motor ability. They can cause disinhibition or aggressive behaviour, facilitate the appearance of delirium, and increase accident and mortality rates in people older than 60. In subjects over 65, low systolic blood pressure is associated with cognitive decline. Maintaining this figure between 130 and 140mm Hg (145 in patients older than 80) is recommended. Hypocholesterolaemia<160mg/dl is associated with increased morbidity and mortality, aggressiveness, and suicide; HDL-cholesterol<40mg/dl is associated with memory loss and increased vascular and mortality risks. Old age is a predisposing factor for developing cognitive disorders or delirium when taking opioids. The risks of prescribing anticholinesterases and memantine to patients with non-Alzheimer dementia that is not associated with Parkinson disease, mild cognitive impairment, or psychiatric disorders probably outweigh the benefits. Anticholinergic drugs acting preferentially on the peripheral system can also induce cognitive side effects. Practitioners should be aware of steroid-induced dementia and steroid-induced psychosis, and know that risk of delirium increases with polypharmacy. Of 500 patients with cognitive impairment, 70.4% were on multiple medications and 42% were taking benzodiazepines. Both conditions were present in 74.3% of all suspected iatrogenic cases. CONCLUSIONS: Polypharmacy should be avoided, if it is not essential, especially in elderly patients and those with cognitive impairment. Benzodiazepines, opioids and anticholinergics often elicit cognitive and behavioural disorders. Moreover, systolic blood pressure must be kept above 130mm Hg, total cholesterol levels over 160mg/dl, and HDL-cholesterol over 40mg/dl in this population.

    ABSTRACT: The benefits of the collaboration between orthopaedics and geriatrics in the management and care of elderly patients admitted with hip fracture have been widely demonstrated. A questionnaire was sent to all hospital geriatricians of Castilla y León in order to determine the characteristics this collaboration between orthopaedics and geriatrics in the public hospitals of Castilla y León. They were asked about the type of collaboration with orthopaedics in the care of the elderly patient admitted with hip fracture and details of the treatment of the complications. Most of the hospitals maintain a high level of orthogeriatric collaboration with geriatricians, and the geriatrician attends to most of the medical complications of these patients. The average hospital stay is 10 days, with a surgical delay of 3 days. Management of the most frequent clinical problems in hospitals of Castilla y León are detailed in this article, comparing them with the latest articles and current recommendations from clinical practice guides.
