RESUMEN

INTRODUCTION: Hip fractures are considered among one of the most disabling injuries in patients older than 60 years of age. This fractures are associated with a high incidence of mortality and it is the leading cause of hospital admission that requires surgical treatment in Orthopaedic Trauma Centers. METHODS: This systematic review aimed to group, classify and report the best level of evidence of physical therapy and rehabilitation of patients that have been treated with osteostynthesis after trochanteric or subtrochanteric fracture. The outcomes of efficacy and safety were return to activities of daily living, independence and rate of complications. RESULTS: We identified 3,889 abstracts from PubMed, and 1,567 abstracts from other sources, after eliminating duplicates, and posterior to a thorough screening 378 abstracts were read. From these, 316 abstracts were excluded, and 62 articles were considered eligible. After reading for relevant outcomes 41 articles were excluded. Synthesis was based in 21 studies. CONCLUSIONS: Long term results of specialized physical therapy, appear to be crucial in the first months after surgery, and not that important after the four months after surgery. Recent literature supports that the differences of daily activities and independence of the patients that survive a hip fracture tend to be similar with no difference in the type of physical therapy.

INTRODUCCIÓN: Las fracturas de cadera se consideran entre las lesiones incapacitantes más comunes en mayores de 60 años. Se asocian a un alto índice de mortalidad y es la causa más frecuente de internamiento que requiere tratamiento quirúrgico en unidades médicas dedicadas a la traumatología. MÉTODOS: Esta revisión sistemática tiene como objetivo agrupar, clasificar y reportar el mejor nivel de evidencia en el manejo de terapia física y rehabilitación en los pacientes con fractura pertrocantérica y subtrocantérica de cadera después de la cirugía de osteosíntesis en desenlaces de actividades de la vida diaria, independencia y complicaciones. RESULTADOS: Se identificaron 3,389 resúmenes y a través de otras fuentes 1,567 resúmenes, se eliminaron duplicados en la búsqueda y posterior a un cribado se obtuvieron 378 artículos para la eliminación adicional. De los 62 ensayos restantes se incluyeron 21 y 41 fueron excluidos. CONCLUSIONES: Los resultados a largo plazo de la terapia física especializada parecen ser cruciales en los primeros meses y no tan importantes al cabo de cuatro meses. La literatura actual sostiene que las diferencias en las capacidades de la vida diaria e independencia de los pacientes que sobreviven, el tratamiento de una fractura de cadera tiende a ser similar independientemente del programa de rehabilitación que se tenga.

RESUMEN

AIM: The aim of this paper was to evaluate the hemodynamic behavior of carotid kinking, as assessed by color Doppler ultrasonography at baseline and during neck movements, and their relation to neurological symptoms. METHODS: In this cross-sectional study, 60 consecutive patients with non-atheromatous carotid kinking in whom diagnostic color Doppler ultrasonography investigation of neck vessels had been requested for clinical suspicion of atherosclerotic disease were evaluated. To evaluate if there were significant changes of blood velocities as a consequence of kinking, for each carotid artery we recorded systolic and diastolic velocities both in the segments proximal to kinking, as well as intra-kinking. The effects of postural changes and neck movements on carotid blood flow were also studied. RESULTS: Flow in carotid arteries with kinking was always normal, and no differences were found between flow velocity measured at the level of kinking compared to the normal tract of the vessel. During head rotation tests, flow remained largely unaffected, a substantial reduction in the velocities in the ophthalmic artery was found in 13.5% of the cases, while an increase was recorded in 27%; and no symptoms or events were recorded during the study. None of the patients referred symptoms, nor were neurological events or signs detected during the maneuvers. CONCLUSION: Our results show that carotid kinks are not a mechanism of acute cerebral ischemia, and therefore are unlikely to be a cause of neurological events or symptoms.

RESUMEN

Serum samples from 313 asymptomatic intravenous (IV) drug users from Bilbao (Vizcaya, Vasque Country, Spain) were tested for antibodies to HTLV-III/LAV virus, the probable etiologic agent of the acquired immune deficiency syndrome (AIDS). Viral antibodies were assayed by ELISA test. 41.9% of the sera gave positive reactions. No seropositivity was detected among 22 normal blood donors, 58 chronic alcoholics, or 20 members of the Drug Control Center personnel. Virus specific reactions were confirmed by indirect immunofluorescence using an HTLV-III/LAV producer cell line, and by Western blotting. 55% of the ELISA-positive sera were also positive in Western blot assay. No differences in seropositivity by age or sex were observed but it increased with the period of parenteral drug use. Presence of antibody statistically correlated with the frequency of syringe sharing, confirming the transmission of viral infection by blood products. Altered T4/T8 ratios and lower number of T4 positive lymphocytes were detected among HTLV-III/LAV positive drug addicts.
