RESUMEN
BACKGROUND: Data on the prevalence and clinical impact of extrapulmonary findings at screening computed tomography (CT) on initiation of veno-venous extracorporeal membrane oxygenation (V-V ECMO) are limited. We aimed to identify the prevalence of extrapulmonary findings on screening CT following V-V ECMO initiation. We hypothesized that extrapulmonary findings would influence clinical management and outcome. METHODS: Retrospective analysis (2011-2021) of admission screening CT including head, abdomen and pelvis with contrast of consecutive patients on initiation of V-V ECMO. CT findings identified by the attending consultant radiologist were extracted. Demographics, admission physiological and laboratory data, clinical decision-making following CT and ECMO ICU mortality were recorded from the electronic medical record. We used multivariable logistic regression and Kaplan-Meier curves to evaluate associations between extrapulmonary findings and ECMO ICU mortality. RESULTS: Of the 833 patients receiving V-V ECMO, 761 underwent routine admission CT (91.4%). ECMO ICU length of stay was 19 days (IQR 12-23); ICU mortality at the ECMO centre was 18.9%. An incidental extrapulmonary finding was reported in 227 patients (29.8%), leading to an invasive procedure in 12/227 cases (5.3%) and a change in medical management (mainly in anticoagulation strategy) in 119/227 (52.4%). Extrapulmonary findings associated with mortality were intracranial haemorrhage (OR 2.34 (95% CI 1.31-4.12), cerebral infarction (OR 3.59 (95% CI 1.26-9.86) and colitis (OR 2.80 (95% CI 1.35-5.67). CONCLUSIONS: Screening CT frequently identifies extrapulmonary findings of clinical significance. Newly detected intracranial haemorrhage, cerebral infarction and colitis were associated with increased ICU mortality.
RESUMEN
INTRODUCTION: The proper use of inhalers is essential for ensuring proper control of the disease. Various studies have shown high levels of improper use and lack of knowledge of the correct technique among patients with asthma. However, less data are available on how health care workers (HCW's) use inhalers. MATERIALS AND METHODS: The study was conducted at a Tertiary Care Hospital in Mumbai. We evaluated the pMDI technique in 141 consecutive adult asthmatics and 100 HCW's. All patients and HCW's were graded out of 10 points for following 10 steps. These were derived from Melani et al.'s study on inhaler mishandling. RESULTS: Techniques of 141 patients and 100 HCW's (55 nurses and 45 doctors) were analyzed. The average technique score among patients ranged from 0 to 10 with a mean of 4.65 ± 2.00. The combined score for health workers ranged from 3 to 9 with a mean of 5.45 ± 1.47. Doctors had a higher score of 6.35 ± 1.33 as opposed to the nurses' score of 4.70 ± 1.13 (P < 0.05). There was no significant difference between scores of nurses and patients (P > 0.05). CONCLUSIONS: Our study highlights the need for better education of not only patients but also health care providers regarding the appropriate use of inhaler devices in order to achieve optimal control of obstructive airway diseases.
RESUMEN
Eosinophilic granulomatosis with polyangitis (EGPA; earlier called Churg-Strauss syndrome) is a small-vessel necrotising vasculitis typically characterised by asthma, lung infiltrates, extra-vascular necrotising granulomas and hyper-eosinophilia. Cardiac disease is a major contributor to disease-related deaths in EGPA. We describe the case of a 39-year-old woman with late onset asthma, allergic rhinosinusitis, and high extra-vascular and peripheral blood eosinophilia, presenting with peripheral neuropathy and pericardial effusion. Early therapy with intravenous corticosteroids led to resolution of the pericardial effusion and significant clinical improvement. The present case also highlights the importance of being vigilant about potentially fatal cardiac complications in patients with EGPA.
