RESUMO

This study analysed the mechanisms of quinolone resistance among enterotoxigenic Escherichia coli (ETEC) in a periurban area of Lima, Peru. The susceptibility to nalidixic acid and ciprofloxacin, the role of Phe-Arg-b-Naphtylamyde inhibitable-(PAbN) efflux pumps, the presence of mutations in gyrA and parC as well as the presence of aac(6')Ib-cr, qepA, qnrA, qnrB, qnrC, qnrD, qnrVC and oqxAB were determined in 31 ETEC from previous case/control studies of children's diarrhoea. Discordances between disk diffusion, with all isolates showing intermediate or fully resistance to nalidixic acid, and minimal inhibitory concentration (MIC), with 7 isolates being below considered resistance breakpoint, were observed. Twenty-one isolates possessed gyrA mutations (19 S83L, 2 S83A). AAC(6') Ib-cr, QnrS, QnrB and QepA were found in 7, 6, 2 and 1 isolates respectively, with 3 isolates presenting 2 transferable mechanisms of quinolone resistance (TMQR) concomitantly. TMQR were more frequent among isolates with MIC to nalidixic acid ranging from 2 to 16 mg/L (p=0.03), while gyrA mutations were more frequent among isolates with nalidixic acid MIC >= 128 mg/L (p=0.0002). In summary, the mechanisms of quinolone resistance present in ETEC isolates in Peru have been described. Differences in the prevalence of underlying mechanisms associated with final MIC levels were observed. The results suggest two different evolutive strategies to survive in the presence of quinolones related to specific bacterial genetic background.

RESUMO

Introducción El perfil de egreso corresponde a una declaración formal de los aprendizajes terminales de una profesión, comprometiendo la formación de una identidad profesional, especificando los principales ámbitos de acción profesional y sus atributos clave asociados a la formación universitaria, los cuales deben describirse para transparentar los compromisos que hacen las instituciones con sus egresados y la sociedad. En Chile no existen actualmente directrices para la formación profesional en Fisioterapia, y es necesario avanzar hacia ese objetivo comenzando con un análisis de lo ofrecido por las universidades actualmente. Objetivo Analizar los perfiles de egreso, sus principales ámbitos de desempeño y competencias declarados en las carreras de Fisioterapia que se imparten en 2021 en Chile. Material y método Se realizó una investigación documental cualitativa de los perfiles de egreso publicados en las páginas web de 41 instituciones de Educación Superior en Chile que imparten la carrera universitaria de Fisioterapia durante el año 2021. Se realizó un análisis de contenido temático asistido por el programa NVivo 12 pro. Resultados Se obtuvieron siete categorías principales que caracterizan los ámbitos de competencias de los perfiles de egreso de Fisioterapia en Chile: intervención; razonamiento clínico; promoción y prevención en salud; investigación; gestión y administración en salud; educación, y emprendimiento e innovación. Conclusiones Los principales ámbitos de desempeño presentes en los perfiles de egreso en los planes de formación de los programas universitarios de Fisioterapia en Chile en el presente estudio permitirán promover una reflexión acerca de los significados prácticos para la formación profesional, y así responder a las demandas profesionales presentes y futuras con una identidad centrada en el movimiento humano como eje de acción profesional (AU)


Introduction The entry-level profile corresponds to a formal statement of an institution about the intended learning outcomes of a profession. This commitment includes developing a professional identity, specifying the main areas of professional activity and its key attributes. Besides, universities’ training must transparentize institutions’ commitments to their graduates and society. There is currently no standard for professional training in Physiotherapy in Chile, and it is necessary to move toward this purpose by starting with an analysis of what universities offer today. Purpose To analyze the main areas of performance and competencies declared in the competency-based exit profile of Physiotherapy entry-level programs delivered in 2021 in Chile. Material and method Qualitative documentary research was carried out of the competency-based exit profile, published on the web sites of 41 Higher Education institutions in Chile that delivered Physiotherapy entry-level University Programs during the 2021. A thematic content analysis was carried out assisted by CAQDAS NVivo 12 pro. Results Seven main categories were obtained that characterize competence areas of the current competency-based exit profile in Physiotherapy entry-level programs in Chile: physiotherapist intervention; clinical reasoning in physiotherapy; promotion and prevention in health; research; health management and administration; education; and entrepreneurship and innovation. Conclusions The main areas of performance present in the exit profiles of the university programs of Physiotherapy in Chile were identified. A reflection would be made about the practical meanings for university professional training in Physiotherapy in Chile to respond to the present and future professionals requirements with the identity centered on the human movement as the axis of professional action (AU)

RESUMO

Household water contamination at point of use depends on human, animal and environmental factors embodying all aspects of a One Health approach. This study investigated the association between household factors, the presence of thermotolerant coliform, and the presence of antibiotic resistant bacteria in drinking water among 314 households with children under 5 in Cajamarca, Peru. This study analysed data from a baseline sampling of a randomized controlled trial, including household surveys covering household water management and factors such as household animals, as well as microbiological data from samples collected from drinking water. Data were analysed using generalized linear models. Drinking water samples collected from narrow-mouthed containers were less likely to be contaminated than samples collected from the faucet (OR = 0.55, p = 0.030) or wide mouthed containers. The presence of thermotolerant coliform was associated with owning farm birds, which increased the proportion of contamination from 42.2% to 59.1% (OR = 1.98, p = 0.017) and with animal waste observed in the kitchen area, which increased the prevalence of contamination from 51.4% to 65.6% (OR = 1.80, p = 0.024). Resistance to any antibiotic was higher among pig owners at 60%, relative to non-pig owners at 36.4% (OR = 1.97, p = 0.012) as well as households with free-roaming animals in the kitchen area at 59.6% compared to households without free-roaming animals at 39.7% (OR = 2.24, p = 0.035). Recent child antibiotic use increased the prevalence of trimethoprim-sulfamethoxazole resistance among E. coli isolates to 22.3% relative to 16.7% (OR = 3.00, p = 0.037). Overall, these findings suggest that water storage in a secure container to protect from in-home contamination is likely to be important in providing safe drinking water at point of use. In addition, transmission of thermotolerant coliform and AMR between domestic animals and human drinking water supplies is likely. Further research should explore transmission pathways and methods to support safe drinking water access in multi-species households.

RESUMO

Resumen Introducción: La enfermedad de Ménière se caracteriza por crisis recurrentes de vértigo, asociado a hipoacusia y tinnitus, que pueden ser incapacitantes, y provocar estrés y ansiedad. Objetivos: Evaluar el efecto de la dexametasona transtimpánica sobre la audición y vértigo en pacientes con enfermedad de Ménière de difícil manejo. Material y Método: Se reclutó a pacientes con enfermedad de Ménière de difícil manejo médico quienes fueron tratados con tres inyecciones transt-impánicas de dexametasona (4 mg/ml). Se realizó audiometría, prueba calórica y dos encuestas de disca-pacidad (DHI y UCLA-DQ) al inicio, tres, y diez semanas posintervención, además de una entrevista a los seis meses. Resultados: Doce pacientes completaron el estudio. Se observó un aumento del promedio de umbrales auditivos hasta 11,25 dB, principalmente entre 125 y 3000 Hz a las tres semanas, y una reducción de éstos hasta 7,5 dB a las diez semanas respecto de los iniciales, principalmente entre 125 y 2000 Hz (no estadísticamente significativo). Todos los pacientes presentaron hipo-excitabilidad vestibular. Se observó una mejoría significativa en el puntaje de la encuesta UCLA-DQ posinterven-ción, manteniéndose durante todo el seguimiento. No se encontraron diferencias estadísticamente significativas en el puntaje global ni subcomponentes de la encuesta DHI. Siete de ocho pacientes reportaron que volverían a utilizar las inyecciones. Conclusión: Los corticoides transtimpánicos pueden ayudar a disminuir la discapacidad e impacto en la calidad de vida de los pacientes con enfermedad de Ménière de difícil manejo a mediano y largo plazo.


Abstract Introduction: Ménière's disease is characterized by recurrent episodes of vertigo, sensorineural hearing loss and aural fullness, which can be incapacitating and cause stress and anxiety. Aim: To assess the effect of transtympanic steroid injections on hearing and vertigo for patients suffering from intractable Ménière's disease. Material and Method: Patients with intractable Ménière's disease were recruited and treated with three transtympanic steroid injections (dexamethasone 4 mg/ml). Audiometric and vestibular assessment, and two dizziness questionnaires (DHI, UCLA-DQ) were performed upon recruitment, three weeks, and ten weeks following the transtympanic treatment. A brief auto-perception survey was applied at 6 months follow-up. Results: Twelve patients completed the study. An increase in the mean auditory threshold was observed up to 11.25 dB, mainly between 125 and 3000 Hz at three weeks, and a reduction of these up to 7.5 dB at ten weeks with respect to the initial ones, mainly between 125 and 2000 Hz (not statistically significant). All patients presented vestibular dysfunction on caloric testing. A significant impro-vement in the UCLA-DQ survey score was observed, remaining throughout the follow-up. No statistically significant differences were found in the overall score or subcomponents of the DHI. Seven out of eight patients reported that they would undergo the injections again. Conclusion: Transtympanic corticosteroids can help to reduce disability and impact on the quality of life of patients with Ménière's disease that is difficult to manage in the medium and long term.

RESUMO

An increase in body temperature accelerates biochemical reactions and behavioral and physiological responses. A mechanism to actively increase body temperature would be beneficial during motivated behaviors. The prefrontal cortex is implicated in organizing motivated behavior; the infralimbic cortex, a subregion of the medial prefrontal cortex, has the necessary connectivity to serve the role of initiating such thermogenic mechanism at the beginning of the appetitive phase of motivated behavior; further, this cortex is active during motivated behavior and its disinhibition produces a marked behavioral and vegetative arousal increase, together with increases in histamine levels. We wanted to explore if this arousal was related to histaminergic activation after pharmacological infralimbic disinhibition and during the appetitive phase of motivated behavior. We measured core temperature and motor activity in response to picrotoxin injection in the infralimbic cortex, as well as during food-related appetitive behavior, evoked by enticing hungry rats with food. Pretreatment with the H1 receptor antagonist pyrilamine decreased thermal response to picrotoxin and enticement and completely blunted motor response to enticement. Motor and temperature responses to enticement were also completely abolished by infralimbic cortex inhibition with muscimol. To assess if this histamine dependent temperature increase was produced by an active sympathetic mediated thermogenic mechanism or was just a consequence of increased locomotor activity, we injected propranolol (i.p.), a ß adrenergic receptor blocker, before picrotoxin injection into the infralimbic cortex. Propranolol reduced the temperature increase without affecting locomotor activity. Altogether, these results suggest that infralimbic activation is necessary for appetitive behavior by inducing a motor and a vegetative arousal increase mediated by central histamine.

RESUMO

OBJECTIVE: The main aim of the present study was to determine the sensitivity, specificity and accuracy of ultrasonography (US) in detecting monosodium urate and calcium pyrophosphate dihydrate crystals deposits at knee cartilage level using clinical definite diagnosis as standard reference. DESIGN: A total of 32 patients with a diagnosis of gout and 48 patients with pyrophosphate arthropathy were included in the study. Fifty-two patients with rheumatoid arthritis (RA), psoriatic arthritis or osteoarthritis (OA) were recruited as disease controls. All diagnoses were made using an international clinical criterion. US examinations were performed by an experienced sonographer, blind to clinical and laboratory data. Hyaline cartilage was assessed to detect two US findings recently indicated as indicative of crystal deposits: hyperechoic enhancement of the superficial margin of the hyaline cartilage and hyperechoic spots within the cartilage layer not generating a posterior acoustic shadow. RESULTS: Hyperechoic enhancement of the chondrosynovial margin was found in at least one knee of 14 out of 32 (43.7%) patients with gout and in a single knee of only one patient affected by pyrophosphate arthropathy (specificity=99%). Intra-cartilaginous hyperechoic spots were detected in at least one knee of 33 out of 48 (68.7%) patients with pyrophosphate arthropathy and in two disease controls one with OA and the second with RA (specificity=97.6%). CONCLUSIONS: The results of the present study indicate that US may play a relevant role in distinguishing cartilage involvement in patients with crystal-related arthropathy. The selected US findings were found to be highly specific.

RESUMO

BACKGROUND: Adequate clinical nutrition care is an integral part of the complete treatment of hospitalised patients, requiring specific knowledge from the health care team. The aim of this study is to assess, in Paraguay, the health care team ability in clinical care nutrition. MATERIALS AND METHODS: A survey was made including 174 people of Paraguay university hospitals (29% physicians, 29% medicine graduating students, 11% pharmaceutics, 24% nurses, 7% dieticians), by answering voluntarily a multiple choice questionnaire of 20 items. RESULTS: The median score of the 20 questions was 6 (0-15). Physicians obtained a median of 6 (2-15), graduating students 7 (2-14), pharmaceutics 7 (0-15), nurses 3 (0-11), and dieticians 9 (4-13). The dieticians obtained a significantly higher score than the other groups (p < 0.005). CONCLUSIONS: The knowledge about clinical nutrition in the health care members from university hospitals is not adequate. The level of education in clinical nutrition is better in the dietician.

RESUMO

El tratamiento de la enfermedad de Ménière continúa siendo controversial. Existen muchos tratamientos disponibles con diferentes efectividades. La terapia transtimpánica es una novedosa arma terapéutica que se está introduciendo gradualmente en el campo de la otología. Este estudio pretende: 1) Evaluar la utilidad de la terapia transtimpánica en el tratamiento de la enfermedad de Ménière. 2) Dar a conocer la experiencia de nuestro centro al respecto. Para ello se evaluó retrospectivamente, por medio de una encuesta telefónica, la respuesta clínica de los pacientes con enfermedad de Ménière que recibieron terapia transtimpánica (corticoides y/o gentamicina) entre los años 2002 y 2004. Se estudió a 34 pacientes, con un promedio de edad de 53 años. El 79,4 por ciento (n=27) presentó una respuesta favorable en relación a su sintomatología vestibular (p=0,02) y un 55,9 por ciento (n=19) refirió mejoría total de ella. Cuatro pacientes que no respondieron a corticoides transtimpánicos recibieron gentamicina intratimpánica, llegando a la parálisis vestibular total y mejoría de su sintomatología vestibular. Se concluye que los corticoides transtimpánicos son efectivos en el tratamiento de la sintomatología vestibular en la enfermedad de Ménière. La gentamicina intratimpanica es una alternativa eficaz para los pacientes que no responden a corticoides transtimpánicos.

RESUMO

La prueba calórica mínima (PCM) es un examen diseñado para estudiar el canal semicircular lateral (CSCL) y, especialmente, el canal semicircular posterior (CSCP), el cual no es examinado por la prueba calórica clásica (PCC). Nuestro objetivo es evaluar el aparato vestibular a través de la PCM, cuando la PCC no explica los síntomas de algunos pacientes. Se incluyeron aquellos pacientes que consultaron entre enero y julio de 2003 por un síndrome vertiginoso cuya sintomatología no era explicada por la PCC. Fueron evaluados mediante PCM. Se identificaron 12 pacientes con estas características. En todos los casos la PCM permitió establecer un diagnóstico más preciso. Como conclusión, la PCM en casos seleccionados complementa la PCC, otorgando información adicional relevante para el manejo de los pacientes con patología vestibular.

RESUMO

El vértigo postural paroxístico benigno (VPPB) es una patología de alta incidencia en el campo de la otorrinolaringología. Para su tratamiento se han descrito una variedad de terapias, destacando entre éstas la maniobra liberadora de Semont y la maniobra de reposición de partículas de Epley, debido a su simplicidad y no ser invasivas. El objetivo de este trabajo es evaluar el efecto de una nueva maniobra de reposición, la cual consiste en cuatro posiciones más que aquella descrita por Epley, en pacientes que presentan vértigo postural paroxístico benigno unilateral, con compromiso del canal semicircular posterior. Para ello se realizó un estudio prospectivo, a 142 pacientes portadores de VPPB unilateral del canal semicircular posterior, a quienes se le efectuó maniobras de reposición de partículas para el canal semicircular afectado. Se practicó un control a las 48 horas con maniobras de provocación de Dix-Hallpike, obteniéndose un 95 por ciento (135 pacientes) de remisión completa de los síntomas. En sólo siete pacientes no hubo un resultado inmediato. Estos fueron tratados con la nueva maniobra de reposición, obteniéndose una mejoría total en cuatro de ellos; en los otros tres pacientes fue necesaria una maniobra de liberación de partículas de Sermont, complementada con una tercera maniobra de reposición, lográndose un 100 por ciento de remisión de los signos y síntomas.

RESUMO

El presente trabajo revisa los hallazgos clínicos, audiométricos, funcionales de VIII par e imagenológicos de una serie consecutiva de 10 pacientes con neurinoma del acústico.En el 50 por ciento de los pacientes se presentó con síntomas atípicos como la sordera súbita o la hipoacusia fluctuante. En el 100 por ciento de los casos existía algún compromiso de la audición; sin embargo, no hubo correlación entre el tamaño del tumor y la cuantía de la pérdida auditiva. El tipo de curva en la audiometría o la alteración de las pruebas supraliminares (discriminación de la palabra, Fowler, umbral de molestia auditiva y deterioro tonal) no permitieron predecir la presencia de un neurinoma. La alteración del reflejo acústico fue la prueba no imagenológica que obtuvo la mayor sensibilidad (80 por ciento). Se observó una asimetría en la prueba calórica sólo en un 40 por ciento de los casos. Se puede concluir que la presentación clínica considerada como típica del neurinoma del acústico, los exámenes no imagenológicos tienen un rol muy limitado. La baja sensibilidad de las pruebas funcionales del VIII par reportada en la literatura y confirmada en esta serie de pacientes debe inducirnos a solicitar estudio con neuroimágenes en todos aquellos casos en los que exista una sospecha clínica. La resonancia nuclear magnética (RNM) con gadolinio fue el examen más idóneo para ello, ya que permitió hacer el diagnóstico en 2 casos en que la tomografía computada (TC) sólo fue de presunción, y en un tercer paciente reveló un tamaño tumoral significativamente mayor al observado en la TC.
