Purpose The management of cervical facet dislocation injuries remains controversial. The main purpose of this investigation was to identify whether a surgeon's geographic location or years in practice influences their preferred management of traumatic cervical facet dislocation injuries. Methods A survey was sent to 272 AO Spine members across all geographic regions and with a variety of practice experience. The survey included clinical case scenarios of cervical facet dislocation injuries and asked responders to select preferences among various diagnostic and management options. Results A total of 189 complete responses were received. Over 50% of responding surgeons in each region elected to initiate management of cervical facet dislocation injuries with an MRI, with 6 case exceptions. Overall, there was considerable agreement between American and European responders regarding management of these injuries, with only 3 cases exhibiting a significant difference. Additionally, results also exhibited considerable management agreement between those with ≤ 10 and > 10 years of practice experience, with only 2 case exceptions noted. Conclusion More than half of responders, regardless of geographical location or practice experience, identified MRI as a screening imaging modality when managing cervical facet dislocation injuries, regardless of the status of the spinal cord and prior to any additional intervention. Additionally, a majority of surgeons would elect an anterior approach for the surgical management of these injuries. The study found overall agreement in management preferences of cervical facet dislocation injuries around the globe.

Abstract. We conducted a prospective cohort study in four hospitals in Lima, Peru in infants with a birth weight 1,500 g followed from birth hospital discharge up to 1 year of age to determine the incidence of respiratory syncytial virus (RSV) hospitalizations. We enrolled 222 infants from March of 2009 to March of 2010: 48 infants with a birth weight 1,000 g and 174 infants with a birth weight of 1,000-1,500 g (birth weight = 1,197 ± 224 g; gestational age = 30.1 ± 2.6 weeks). There were 936 episodes of respiratory infections; the incidence of respiratory infections during the first 1 year of life was 5.7 episodes/child-years. The incidence of RSV respiratory infections that required emergency room management was 103.9 per 1,000 child-years, and the incidence of RSV hospitalizations was 116.2 per 1,000 child-years (244.9 in infants with a birth weight 1,000 g and 88.9 in infants 1,000-1,500 g; P 0.05). The incidence of RSV respiratory infections that required emergency management or hospitalization is high among pre-mature infants in Lima.

ResumenObjetivo: Conocer los patrones de compromiso cardíaco en pacientes infectados por el virus de inmunodeficiencia humana en estadio SIDA. Material y Métodos: Estudio prospectivo de pacientes ambulatorios del Hospital Nacional Guillermo Almenara Irigoyen (HNGAI), que incluyó una evaluación de los parámetros clínico-epidemiológicos, así como una evaluación ecocardiográfica realizada entre marzo de 2002 y marzo de 2003. Resultados: Ciento treinta y dos pacientes fueron evaluados. Tuvieron 40,4 años en promedio (DE 8,7). La mediana del tiempo de diagnóstico fue 48 meses (RIQ 50) y recibieron terapia antiretroviral 63,6%. Los patrones de compromiso cardíaco fueron agrupados en disfunción diastólica (DD) en 28,8%, disfunción sistólica en 3,0%, y derrame pericárdico en 9,1%. La DD se asoció a una historia de internamientos anteriores así como a una mayor edad. Conclusiones: Encontramos un alto porcentaje de anormalidades cardíacas en pacientes ambulatorios con SIDA. La DD fue el hallazgo más frecuente. Palabras clave: Síndrome de inmunodeficiencia adquirida; enfermedades cardiovasculares; ecocardiografía. Cardiac compromise in AIDS. First peruvian report AbstractObjective: To determine the patterns of cardiac compromise in patients infected by human immunodeficiency virus in AIDS-stage. Material and Methods: Prospective study of ambulatory patients at Guillermo Almenara Irigoyen National Hospital between March 2002 and March 200, included assessment of clinical and epidemiological parameters and echocardiographic study. Results: One hundred and thirty-two patients were studied. They had a mean age of 40,4 years (SD 8,7). The median time for AIDS diagnosis was 48 months (IQR 50) and received antiretroviral therapy 63,6%. Cardiac compromise patterns were diastolic dysfunction (DD) in 28,8%, systolic dysfunction in 3,0%, pericardial effusion in 9,1%. DD was associated with a history of previous hospitalization and older age. Conclusions: We found a high percentage of cardiac abnormalities in patients with HIV infection in AIDS stage. DD was the most frequent finding.
