Benign acquired subluxation of the knee.

PURPOSE: To describe several cases of recurrent femorotibial subluxation episodes in pediatric patients, to review the existing literature about this rare entity, and to characterize its different clinical presentations. MATERIALS AND METHODS: The study included a series of three cases seen at our center. All patients underwent a structured anamnesis and complete physical examination, as well as a basic radiological study. One underwent magnetic resonance imaging. A literature search was performed in the main databases under the terms "Snapping knee" and "Femorotibial subluxation in child" to consult previous studies. RESULTS: Clinical onset was between 6 and 14 months of age, with episodes of femorotibial subluxations associated with irritability or fever. Examination showed increased joint laxity and a discrete genu valgum. Imaging studies showed no anatomical alterations. The symptoms gradually decreased in intensity and frequency. Two of the patients were treated with extension splints with no differences between them or with respect to the patient in whom therapeutic abstention was chosen. CONCLUSIONS: There are two independent presentations of the pathology that have not been well differentiated so far. The first (patients described from our clinical practice) is in initially healthy children who begin with episodes of subluxation in relation to febrile episodes or irritability, with an anodyne physical examination, and benign evolution with progressive reduction of the episodes even without treatment. The second presents as episodes of anterior subluxation since birth in patients with associated pathologies (usually spinal), anterior cruciate ligament instability, and need for surgical treatment to reduce the number of episodes.

Mental health in the Americas: an overview of the treatment gap.

OBJECTIVE: To understand the mental health treatment gap in the Region of the Americas by examining the prevalence of mental health disorders, use of mental health services, and the global burden of disease. METHODS: Data from community-based surveys of mental disorders in Argentina, Brazil, Canada, Chile, Colombia, Guatemala, Mexico, Peru, and the United States were utilized. The World Mental Health Survey published data were used to estimate the treatment gap. For Canada, Chile, and Guatemala, the treatment gap was calculated from data files. The mean, median, and weighted treatment gap, and the 12-month prevalence by severity and category of mental disorder were estimated for the general adult, child-adolescent, and indigenous populations. Disability-adjusted Life Years and Years Lived with Disability were calculated from the Global Burden of Disease study. RESULTS: Mental and substance use disorders accounted for 10.5% of the global burden of disease in the Americas. The 12-month prevalence rate of severe mental disorders ranged from 2% - 10% across studies. The weighted mean treatment gap in the Americas for moderate to severe disorders was 65.7%; North America, 53.2%; Latin America, 74.7%; Mesoamerica, 78.7%; and South America, 73.1%. The treatment gap for severe mental disorders in children and adolescents was over 50%. One-third of the indigenous population in the United States and 80% in Latin America had not received treatment. CONCLUSION: The treatment gap for mental health remains a public health concern. A high proportion of adults, children, and indigenous individuals with serious mental illness remains untreated. The result is an elevated prevalence of mental disorders and global burden of disease.

RESUMEN Objetivo Comprender la brecha en el tratamiento de la salud mental en la Región de las Américas mediante la revisión de la prevalencia de los trastornos de salud mental, el uso de los servicios de salud mental y la carga mundial de enfermedad. Métodos Se utilizaron datos de encuestas comunitarias de trastornos mentales de Argentina, Brasil, Canadá, Chile, Colombia, Estados Unidos, Guatemala, México y Perú. Se emplearon los datos publicados de la Encuesta Mundial de Salud Mental para estimar la brecha de tratamiento. Para Canadá, Chile y Guatemala, la brecha de tratamiento se calculó a partir de los archivos de datos. Se estimaron la brecha de tratamiento media, media ponderada, y mediana, y la prevalencia de 12 meses por gravedad y categoría de trastorno mental para las poblaciones generales de adultos, niños y adolescentes, e indígenas. Se calcularon los años de vida ajustados por discapacidad y los años vividos con discapacidad a partir del estudio Carga Global de Enfermedad. Resultados Los trastornos mentales y por consumo de sustancias representaron el 10,5% de la carga mundial de enfermedad en las Américas. La tasa de prevalencia de 12 meses de los trastornos mentales severos varió del 2% al 10% en los estudios. La brecha de tratamiento media ponderada en las Américas para los trastornos moderados a graves fue del 65,7%; en América del Norte de 53,2%; en América Latina de 74,7%; en Mesoamérica de 78,7%; y en América del Sur de 73,1%. La brecha de tratamiento para los trastornos mentales graves en niños y adolescentes fue superior al 50%. Un tercio de la población indígena en los Estados Unidos y el 80% en América Latina no recibieron tratamiento. Conclusión La brecha de tratamiento para la salud mental sigue siendo un problema de salud pública. Una gran proporción de adultos, niños y personas indígenas con enfermedades mentales graves continúan sin tratamiento. El resultado implica una prevalencia elevada de trastornos mentales y de la carga mundial de enfermedad.

RESUMO Objetivo Compreender a lacuna de tratamento em saúde mental na Região das Américas examinando a prevalência de transtornos mentais, o uso de serviços de saúde mental e a carga global de doença. Métodos Foram utilizados dados de inquéritos comunitários de transtornos mentais na Argentina, Brasil, Canadá, Chile, Colômbia, Guatemala, México, Peru e Estados Unidos. Os dados publicados na Pesquisa Mundial de Saúde Mental foram utilizados para estimar a lacuna de tratamento. Para o Canadá, Chile e Guatemala, a lacuna de tratamento foi calculada a partir de arquivos de dados. A lacuna de tratamento média, média ponderada e mediana, e a prevalência de 12 meses por gravidade e categoria de transtorno mental foram estimadas para as populações adulta, infantil-adolescente e indígena em geral. Os anos de vida ajustados por incapacidade e os anos de vida com incapacidade foram calculados a partir do estudo Carga Global de Doença. Resultados Os transtornos mentais e de uso de substâncias foram responsáveis por 10,5% da carga global de doença nas Américas. A taxa de prevalência de 12 meses de transtornos mentais graves variou de 2% a 10% entre os estudos. A lacuna de tratamento média ponderada nas Américas para transtornos moderados a graves foi de 65,7%; em América do Norte de 53,2%; em América Latina de 74,7%; em Mesoamérica de 78,7%; e na América do Sul de 73,1%. A lacuna de tratamento para transtornos mentais graves em crianças e adolescentes foi superior a 50%. Um terço da população indígena nos Estados Unidos e 80% na América Latina não recebeu tratamento. Conclusão A lacuna de tratamento para a saúde mental continua sendo uma preocupação de saúde pública. Uma alta proporção de adultos, crianças e indígenas com doença mental grave permanece sem tratamento. O resultado é uma elevada prevalência de transtornos mentais e de carga global de doença.

Eventos violentos anteriores y resultados de salud mental en Guatemala

Objetivos. Analizamos una muestra probabilística de los guatemaltecos para determinar si existe una relación entre eventos violentos anteriores y el desarrollo de resultados de salud mental en diversos grupos sociodemográficos, así como durante la guerra civil guatemalteca y después ella. Métodos. Usamos el modelado de regresión, una prueba de interacciones y complejos ajustes del diseño de encuestas para hacer una estimación de la prevalencia y examinar las posibles relaciones entre los eventos violentos anteriores y la salud mental. Resultados. Muchos de los participantes (20,6%) habían presenciado o sufrido anteriormente al menos un evento violento grave. Ser testigo de cómo alguien fue herido gravemente o asesinado fue el evento más frecuente. El 4,2% de los participantes presentaron depresión; 6,5%, ansiedad; 6,4%, un trastorno relacionado con el alcohol; y 1,9% un trastorno de estrés postraumático (TEPT). Las personas que presenciaron o fueron víctimas de la violencia durante la guerra tenían una probabilidad ajustada 4,3 veces mayor de presentar trastornos relacionados con el alcohol (P <0,05) y una probabilidad ajustada 4,0 veces mayor de TEPT (P < 0,05) en comparación con el periodo de posguerra. Las mujeres, los indígenas mayas y los habitantes de zonas urbanas tenían mayor probabilidad de presentar resultados de salud mental posteriores a la violencia. Conclusiones. La violencia que empezó durante la guerra civil y que actualmente se mantiene tiene un efecto importante en la salud mental de los guatemaltecos. Sin embargo, los resultados de salud mental como resultado de eventos violentos disminuyeron en el periodo de posguerra, lo que hace pensar que la nación se está recuperando.

Objectives. We analyzed a probability sample of Guatemalans to determine if a relationship exists between previous violent events and development of mental health outcomes in various sociodemographic groups, as well as during and after the Guatemalan Civil War. Methods. We used regression modeling, an interaction test, and complex survey design adjustments to estimate prevalences and test potential relationships between previous violent events and mental health. Results. Many (20.6%) participants experienced at least 1 previous serious violent event. Witnessing someone severely injured or killed was the most common event. Depression was experienced by 4.2% of participants, with 6.5% experiencing anxiety, 6.4% an alcohol-related disorder, and 1.9% posttraumatic stress disorder (PTSD). Persons who experienced violence during the war had 4.3 times the adjusted odds of alcohol-related disorders (P < .05) and 4.0 times the adjusted odds of PTSD (P < .05) compared with the postwar period. Women, indigenous Maya, and urban dwellers had greater odds of experiencing postviolence mental health outcomes. Conclusions. Violence that began during the civil war and continues today has had a significant effect on the mental health of Guatemalans. However, mental health outcomes resulting from violent events decreased in the postwar period, suggesting a nation in recovery.
