RESUMO
Castleman disease (CD) is a rare lymphoproliferative disorder with variable presentation and prognosis. Most CD cases are unicentric and correspond to the hyaline-vascular variant, a histopathological classification associated with better outcomes, which commonly presents as an enhancing hypervascular mediastinal mass. CD is often asymptomatic and surgically resectable. Nonetheless, surgical resection can be difficult when the lymphoid mass is causing compression of vital structures. We discuss a rare case of hyaline-vascular unicentric CD presenting as an incidental pericardial mass.
RESUMO
Background: There have been varying reports on the prevalence of antineutrophil cytoplasmic antibodies with bactericidal/permeability-increasing protein (BPI-ANCA) specificity in cystic fibrosis (CF) patients. These autoantibodies are believed to develop in response to infection and colonization, especially with Pseudomonas aeruginosa. The aim of this review was to estimate the overall prevalence of BPI-ANCA in CF patients. Methods: We searched PubMed, Scopus, and Embase databases for studies reporting the prevalence of BPI-ANCA in CF patients. We also searched the Journal of Cystic Fibrosis and our institution's library for relevant studies on BPI-ANCA. We calculated the proportion with a 95% confidence interval (CI) to assess the prevalence of BPI-ANCA in the individual studies and then pooled the results using a random effects model. Publication bias was assessed using graphical and statistical methods. Finally, we assessed statistical heterogeneity using the I 2 test. Results: Our search yielded 12 eligible studies published between 1996 and 2015. The prevalence of BPI-ANCA in patients with CF varied from 17.9% to 83% with a pooled prevalence of 49.45% (95% CI 35.53-63.42). No evidence of bias was found. However, there was evidence of statistically significant variation in the prevalence estimate due to heterogeneity (I 2 = 93.4%, P < 0.01). Conclusions: Given the highly varying prevalence of BPI-ANCA in patients with CF, more well-designed prospective clinical studies are needed to determine its true prevalence and clinical relevance.
RESUMO
La incidencia y prevalencia de la diabetes mellitus ha aumentado exponencialmente a nivel mundial en las últimas décadas. Los pacientes diabéticos presentan mayor probabilidad de sufrir graves complicaciones, en los procedimientos quirúrgicos en relación a la población general. El presente artículo tiene como objetivo, describir la repercusión del estado hiperglucémico perioperatorio en la etapa postoperatoria en pacientes diabéticos. Para el logro del objetivo planteado se realizó la consulta de diversas obras, que abarcan los resultados de investigación con diferentes modalidades relacionadas con la temática. Se pudo apreciar que la hiperglucemia perioperatoria se vincula con resultados adversos en pacientes a los que se les realiza cirugía general y que padecen diabetes mellitus, sin embargo, en los pacientes que se ha logrado control glicémico con terapia insulínica antes de la intervención, no presentaron mayor riesgo, que el que aparece en sujetos con buen control metabólico. La regulación de la glucosa en la etapa perioperatoria es un parámetro importante en el paciente diabético, que reduce considerablemente las complicaciones en los procedimientos quirúrgicos, las prolongadas estancias en las Unidades de Cuidados Intensivos, e incluso, la muerte.
The incidence and prevalence of diabetes mellitus has increased exponentially worldwide in recent decades. Diabetic patients are more likely to suffer serious complications in surgical procedures compared to the general population. The objective of this article is to describe the repercussion of the perioperative hyperglycemic state in the post-surgical stage in diabetic patients. In order to achieve the stated objective, various works were consulted, which include the results of research with different modalities related to the subject. It was possible to appreciate that perioperative hyperglycemia is associated with adverse results in general surgery patients with diabetes mellitus, however, in patients who have achieved glycemic control with insulin therapy before the intervention, they did not present a greater risk than that which appears in subjects with good metabolic control. Glucose regulation in the perioperative stage is an important parameter in diabetic patients, which considerably reduces complications in surgical procedures, long stays in Intensive Care Units, and even death.
