RADICAL VERSUS CONSERVATIVE METHODS IN ONE-STAGE PILONIDAL ABSCESS SURGERY: THE EXPERIENCE OF A TUNISIAN CENTER.

BACKGROUND: Surgical treatment for pilonidal abscess is the gold standard, but not yet well codified. Different techniques proposed can be conservative or radical. AIMS: The aim of our study was to compare postoperative outcomes of both methods in one-stage treatment strategy. METHODS: This is a comparative study including patients operated on for pilonidal abscess, with a satisfactory postoperative follow-up, over a period of 4 years. We looked for the occurrence of postoperative recurrence in the medical records or by interviewing reachable patients. RESULTS: We analyzed 57 patients: 33 males and 24 females. The mean age was 26.9±10 years. The type of operation was excision in 46 (81%) cases and incision in 11 (19%) cases associated with curettage in three cases and drainage in 1 case. There was no statistically significant relationship between the type of surgery and the occurrence of postoperative surgical complications (p=1) and hospital stay (p=0.4). Excision of pilonidal abscess was significantly associated with a longer time to return to activity (p=0.04). Conservative surgery was significantly associated with faster healing of the surgical wound (p<0.001). The recurrence rate was 19% in radical surgery and 54% in conservative surgery. Radical surgery was significantly associated with a lower recurrence rate than incision procedure (p=0.02). CONCLUSIONS: Excision of pilonidal abscess was the common technique in our series, with a significantly lower rate of recurrence of the disease than after incision. However, the long convalescence following excision and the longer operating time, particularly in an emergency context, may sometimes lead to choosing conservative surgery.

Improved Durability to SARS-CoV-2 Vaccine Immunity following Coimmunization with Molecular Adjuvant Adenosine Deaminase-1.

Although severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines have demonstrated strong immunogenicity and protection against severe disease, concerns about the duration and breadth of these responses remain. In this study, we show that codelivery of plasmid-encoded adenosine deaminase-1 (pADA) with SARS-CoV-2 spike glycoprotein DNA enhances immune memory and durability in vivo. Coimmunized mice displayed increased spike-specific IgG of higher affinity and neutralizing capacity as compared with plasmid-encoded spike-only-immunized animals. Importantly, pADA significantly improved the longevity of these enhanced responses in vivo. This coincided with durable increases in frequencies of plasmablasts, receptor-binding domain-specific memory B cells, and SARS-CoV-2-specific T follicular helper cells. Increased spike-specific T cell polyfunctionality was also observed. Notably, animals coimmunized with pADA had significantly reduced viral loads compared with their nonadjuvanted counterparts in a SARS-CoV-2 infection model. These data suggest that pADA enhances immune memory and durability and supports further translational studies.

RESUMO RACIONAL: O tratamento cirúrgico do abscesso pilonidal é a indicação habitual, mas ainda não está bem codificado. Diferentes técnicas propostas podem ser conservadoras ou radicais. OBJETIVOS: Comparar os resultados pós-operatórios de ambos os métodos, em uma única etapa da estratégia de tratamento. MÉTODOS: Estudo comparativo incluindo todos os pacientes operados por abscesso pilonidal, com um seguimento pós-operatório satisfatório, durante um período de 4 anos. Foi avaliada a ocorrência de recidiva pós-operatória nos prontuários médicos ou entrevistando pacientes. RESULTADOS: Foram incluídos no estudo 57 pacientes: 33 homens e 24 mulheres. A média de idade foi de 26,9±10 anos. O tipo de operação foi a excisão em 46 casos (81%) e a incisão em 11 casos (19%) associada à curetagem em três casos e a drenagem em um caso. A excisão do abscesso pilonidal foi significativamente associada a um tempo maior para retornar à atividade (p=0,04). A cirurgia conservadora foi significativamente associada a uma cicatrização mais rápida da ferida cirúrgica (p<0,001). A taxa de recidiva foi de 19% em cirurgia radical e de 54% em cirurgia conservadora. A cirurgia radical foi significativamente associada a uma taxa de recidiva menor do que o procedimento de incisão (p=0,02). CONCLUSÕES: A excisão do abscesso pilonidal foi a técnica comum nesta casuística, com taxa de recidiva da doença significativamente menor do que após a incisão. No entanto, a longa convalescença após a excisão e o maior tempo de operação, pode às vezes levar à escolha de uma cirurgia conservadora.

Mental health in the Americas: an overview of the treatment gap / La salud mental en las Américas: una visión general de la brecha de tratamiento / Saúde mental nas Américas: uma visão geral da lacuna de tratamento

ABSTRACT 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.

The role of radiation therapy in pediatric mucoepidermoid carcinomas of the salivary glands.

OBJECTIVE: To investigate the role of radiation therapy in rare salivary gland pediatric mucoepidermoid carcinoma (MEC). STUDY DESIGN: A French multicenter retrospective study (level of evidence 4) of children/adolescents treated for MEC between 1980 and 2010 was conducted. RESULTS: Median age of the 38 patients was 14 years. Parotid subsite, low-grade, and early primary stage tumors were encountered in 81%, 82%, and 68% of cases, respectively. All except 1 patient were treated by tumoral surgical excision, and 53% by neck dissection (80% of high grades). Postoperative radiation therapy and chemotherapy were performed in 29% and 11% of cases. With a median 62-month follow-up, overall survival and local control rates were 95% and 84%, respectively. There was 1 nodal relapse. Lower grade and early stage tumors had better survival. Postoperative radiation therapy and chemotherapy were associated with similar local rates. Patients with or without prior cancer had similar outcomes. CONCLUSIONS: Pediatric salivary gland MEC carries a good prognosis. Low-intermediate grade, early-stage tumors should be treated with surgery alone. Neck dissection should be performed in high-grade tumors. Radiation therapy should be proposed for high grade and/or advanced primary stage MEC. For high-grade tumors without massive neck involvement, irradiation volumes may be limited to the primary area, given the risk of long-term side effects of radiation therapy in children. Pediatric MEC as second cancers retain a similar prognosis. Long-term follow-up is needed to assess late side effects and second cancers.
