Cytologic sampling is the mainstay of diagnosing advanced lung cancer. Moreover, to select patients for personalized first-line or second-line treatment, epidermal growth factor receptor (EGFR) mutations and anaplastic lymphoma kinase (ALK) and c-ros oncogene 1 (ROS1) rearrangements are tested on cytologic preparations. Commercially available fluorescence in situ hybridization (FISH) and immunocytochemistry (ICC) assays have primarily been used for the identification of cells harboring ALK or ROS1 gene fusions on histologic rather than cytologic preparations...

Cytological observations of microsporogenesis in the allotriploid lily cultivar 'Cocossa' showed that viable pollen production could be attributed mainly to disoriented spindles, abnormal cytokinesis, and cytomixis during male meiosis. To identify the reasons why the allotriploid lily cultivar 'Cocossa' can produce aneuploid and euploid functional male gametes and can be used as the paternal parent in lily introgression breeding, we performed a detailed investigation of microsporogenesis using the conventional cytological methods...

HPV-based screening provides greater protection against cervical cancer (CC) than cytology-based strategies. Currently, several molecular diagnostic assays for the detection of human papillomavirus (HPV) are available. In this study, we analyzed 5 different HPV testing and genotyping techniques (Hybrid Capture 2 [HC2; Qiagen, Hilden, Germany], AnyplexTMII HPV28 [Anyplex; Seegene, Seoul, Korea], Linear Array [Roche, Branchburg, NJ, USA], GP5+/6+ PCR-EIA-RH [Labo Bio-medical Products, Rijswijk, The Netherlands] and CLART2 [Genomica, Madrid, Spain]) in 295 women referred to the hospital Colposcopy Clinic from 2007 to 2008 due to positive HPV test results or an abnormal Pap test...

BACKGROUND: Feedback tools for clinical audit data that compare site-specific results to average performance over all sites can be useful for quality improvement. Proposed tools should be simple and clearly benchmark the site's performance, so that a relevant action plan can be directly implemented to improve patient care services. We aimed to develop such a tool in order to feedback data to UK HIV clinics participating in the 2015 British HIV Association (BHIVA) audit assessing compliance with the 2011 guidelines for routine investigation and monitoring of adult HIV-1- infected individuals...

OBJECTIVE: Endoscopic ultrasound-guided-fine needle aspiration (EUS-FNA) is an established first-line procedure in the management of solid and cystic pancreatic masses. Lymphoma is an uncommon diagnosis in EUS-FNA of the pancreas, and it is more common for such a diagnosis to be because of secondary involvement of the pancreas by a lymphoproliferative disorder than for this to represent isolated primary pancreatic lymphoma (PPL). We present the clinical, EUS and cytological features of these lesions...

BACKGROUND: Bronchiectasis is characterized by abnormal and permanent dilation of the bronchi, caused by the perpetuation of inflammation and impairment of mucociliary clearance. Physiotherapy techniques can help to decrease the retention of respiratory secretions. The flutter valve combines high-frequency oscillation and positive expiratory pressure to facilitate the removal of secretions. We evaluated the effects of the flutter valve on sputum inflammation, microbiology, and transport of respiratory secretions in patients with bronchiectasis...
