BACKGROUND AND OBJECTIVE Excimer laser photorefractive keratectomy (PRK) is performed at the Singapore National Eye Centre (SNEC) with a minimum period of 3 months between first and second eye treatment. During this period, iatrogenic anisometropia may occur, which can lead to significant visual disability. We analyzed the reasons why some patients delayed(More)
BACKGROUND To examine the common presentations and management of acute epiglottitis in adults. METHOD Retrospective clinical study of 17 consecutive adult patients who presented to the Royal Melbourne Hospital between January 1988 and December 2000 was undertaken. RESULTS The mean patient age was 47 years (range 20-87 years) and the male-to-female ratio(More)
OBJECTIVE To evaluate the yield and cost effectiveness of transbronchial needle aspiration (TBNA) in the assessment of mediastinal and/or hilar lymphadenopathy. DESIGN Retrospective study. SETTING A university hospital. POPULATION STUDIED Ninety-six patients referred for bronchoscopy with computed tomographic evidence of significant mediastinal or(More)
To evaluate our experience with the cytodiagnosis of primary lung cancers by transthoracic fine-needle aspiration (TFNA), 106 bronchogenic carcinomas (BC) and 6 neuroendocrine tumors of the lung (NTL) with adequate needle aspirates were reviewed. The cytodiagnostic accuracy rates of BCs were 75.5%, 72%, 100%, 53%, and 50% for bronchogenic adenocarcinomas,(More)
Computer simulation creates not only the potential to improve many functions within the U.S. Army aviation's condition-based maintenance paradigm, but it also holds the capability to help enhance the CBM vision of achieving optimal operational readiness of the fleet. Therefore, instead of focusing on answering whether computer simulation modeling can be(More)
