Cerebrospinal fluid drainage-related ventriculitis due to multidrug-resistant microorganisms / Ventriculitis asociadas a dispositivos de drenaje de líquido cefalorraquídeo causadas por microorganismos multirresistentes

Introduction: The aim of the study was to analyze the clinical and microbiological characteristics of adult patients with cerebrospinal fluid (CSF) drainage-related ventriculitis. Methods: Retrospective study from January 2010 to June 2019 performed in the Complexo Hospitalario Universitario de Vigo (Spain). Cases of CSF drainage-related ventriculitis in patients ≥18-year-old were gathered. Clinical characteristics of patients, type of drainage devices, management and microbiological isolates were analyzed. Results: Ninety-one episodes of CSF drainage-related ventriculitis were identified. The most frequent organisms isolated were Gram-positive cocci (65%), mainly Staphylococcus epidermidis (48%). Multidrug-resistant microorganisms were detected in 21 episodes (23%). In multivariate analysis, the independent factors related with multidrug-resistant ventriculitis were the length of hospital stay >14 days (HR 6.7; 95%CI 1.75–25.86, p=0.006) and previous antimicrobial therapy (HR 5.58; 95%CI 1.44–21.65, p=0.013). Conclusions: Our study shows a large number of drainage-related ventriculitis episodes caused by multidrug-resistant organisms and reinforce the importance of a judicious use of antibiotics.(AU)

Introducción: El objetivo del estudio fue analizar las características clínicas y microbiológicas de pacientes adultos con ventriculitis asociada a dispositivos de drenaje de líquido cefalorraquídeo (VaD-LCR). Métodos: Estudio retrospectivo entre enero de 2010 y junio de 2019 realizado en el Complexo Hospitalario Universitario de Vigo (España). Se recogieron los casos de VaD-LCR y se analizaron las características clínicas, los tipos de drenaje, el tratamiento y los aislamientos microbiológicos. Resultados: Se identificaron 99 episodios de VaD-LCR. Los microorganismos más frecuentemente aislados fueron los cocos grampositivos (65%), principalmente Staphylococcus epidermidis (48%). Se detectaron microorganismos multirresistentes en 21 episodios (23%). En el análisis multivariante, los factores asociados con VaD-LCR por cepas multirresistentes fueron la estancia hospitalaria >14días (HR: 6,7; IC95%: 1,75-25,86; p=0,006) y el uso previo de antibióticos (HR: 5,58; IC95%: 1,44-21,65; p=0,013). Conclusiones: En nuestro estudio la tasa de VaD-LCR causada por bacterias multirresistentes fue elevada. Estos datos refuerzan la importancia del uso adecuado de antibióticos.(AU)

Mucinosis y vasculitis a nivel uterino asociadas a lupus eritematoso / Uterine mucinosis and vasculitis associated with lupus erythematous

Uterine mucinosis and vasculitis associated with lupus erythematous(AU)

The association of cutaneous papulonodular mucinosis with lupus erythematosus has long been recognized. Massive cutaneous deposits of mucin and periorbital mucinosis have also been reported in patients with lupus. Recently, a report was published of two cases of mucin deposits in the myometrium of patients with lupus, denominated "myxoidosis" by the authors. A case is presented of vasculitis and diffuse, predominately myometrial, mucinosis, in the uterus of a patient with lupus erythematosus. The term "mucinosis" and not "myxoidosis" is recommended, even when referring to the uterus, in order to unify the terminology of pathological findings that have similar histological and histochemical features to the cutaneous lesions found in lupus erythematosus(AU)
