AIMS To determine the role of Perls' staining in bone marrow trephine biopsy sections. METHODS The haemosiderin content of 155 Perls' stained, formic acid decalcified trephine biopsy sections was assessed and compared with Perls' stained aspirate samples in 105 cases and haematoxylin and eosin (H&E) stained biopsy sections in all cases. RESULTS An evaluable aspirate film with positive iron ...
BACKGROUND The diagnosis of pulmonary tuberculosis presents challenges in children because symptoms are non-specific, specimens are difficult to obtain, and cultures and smears of Mycobacterium tuberculosis are often negative. We assessed new diagnostic approaches for tuberculosis in children in a resource-poor country. METHODS Children with symptoms suggestive of pulmonary tuberculosis (case...
Abstract This paper focuses on a phenomenon known as pre-aspiration, defined period of glottal friction found in the sequences sonorants and phonetically voiceless obstruents, hit [hɪ h t], hat [hæ hiss s], cash [kæ ʃ]. Pre-aspiration has been reported North American English ( Clayards Knowles 2015 ); however, there are no systematic studies pre-aspiration this part English-speaking world. Our ...
BACKGROUND Accurate data on childhood pneumonia aetiology are essential especially from regions where mortality is high, in order to inform case-management guidelines and the potential of prevention strategies such as bacterial conjugate vaccines. Yield from blood culture is low, but lung aspirate culture provides a higher diagnostic yield. We aimed to determine if diagnostic yield could be inc...
BACKGROUND The RightLevelpH indicator is a new device designed to measure the pH of gastric aspirate obtained via a nasogastric tube while minimizing exposure of the operator. OBJECTIVE To validate the RightLevelpH indicator in vivo and in vitro. METHODS With general anesthesia, 20 patients had placement of a nasogastric tube and a gastric pH electrode catheter after endotracheal intubation...
OBJECTIVE To evaluate the utility of endotracheal aspirate microscopy, culture and endotracheal tube tip culture for early diagnosis of ventilator-associated pneumonia in neonates. METHODS Inborn ventilated neonates were followed-up for ventilator-associated pneumonia using Center for Disease Control and Prevention (CDC) criteria. Endotracheal aspirate microscopy, culture and endotracheal tub...
INTRODUCTION Bone marrow examination is an indispensable diagnostic tool to evaluate neoplastic and non neoplastic hematological diseases. AIMS To compare bone marrow aspirate with trephine biopsy in hematological disorders. To determine the optimum trephine preprocessing length in lymphoma infiltration. METHODS Diagnostic comparison was done between simultaneous bone marrow aspirates and t...
