RESUMEN
Hypertrophic pulmonary osteoarthropathy (HPOA) is a well-documented complication of pulmonary malignancy and cystic fibrosis (CF). However, HPOA associated with exacerbations of non-CF bronchiectasis has only been reported once previously in an adolescent. We describe a case of an adult patient with bronchiectasis and HPOA, whose joint symptoms flared during pulmonary exacerbations and improved with treatment of each exacerbation.
RESUMEN
No standardised, comprehensive approach to rapid on-site evaluation (ROSE) of cytology samples currently exists. Recent meta-analysis indicates variation in the effectiveness of ROSE, however, reviews commonly omit the details of how ROSE is conducted. This review demonstrates the clinical effectiveness of single slide assessment (SSA) for ROSE of cytology samples, providing a highly effective, standardised methodology, maximising cell yield and the diagnostic potential of samples obtained via endobronchial or endoscopic ultrasound. Advances in molecular testing and immunotherapy now allow patients to access sophisticated, targeted cancer treatments and, consequently, obtaining diagnostic material alone is no longer sufficient. SSA uses specific criteria, based on the morphological presentation, to ensure sufficient material is obtained through one procedure, allowing for all the molecular profiling and tumour expression testing required to provide the patient and clinicians with the optimal treatment options. In total, 450 endobronchial or endoscopic ultrasound procedures were conducted with ROSE SSA performed by a biomedical scientist between 2010 and 2017. In 97% of cases, ROSE SSA matched the final report (inadequate vs adequate-benign material vs malignancy). ROSE SSA provided sufficient material for immunocytochemistry in 200/208 cases (96%) and for additional molecular testing/tumour profiling in 92% (85/92) of cases. The median number of needle passes was three. ROSE SSA streamlines diagnostic pathways; minimising risk of complications to patients, reducing cost and delays to treatment associated with repeat or more invasive procedures. Using SSA, sufficient material for a comprehensive diagnosis can be obtained in one procedure.
