A Prospective Study

Aim A prospective study was undertaken to assess the diagnostic value and therapeutic usefulness of fibreoptic bronchoscopy in the critically ill. Method Fifty-six bronchoscopies were performed in fifty patients. Biochemical, radiological, microbiological and clinical assessments were made before and after each procedure. Results Eighteen fibreoptic bronchoscopies were performed for therapeutic indications (32.1%) of which ten (55.6%) yielded a useful outcome. Thirty-eight bronchoscopies were for diagnostic purposes (67.8%) of which 22 (5 7.9%) were clinically useful. Broncho-alveolar lavage was performed in twenty-eight cases (50%) and it led to a clinically useful diagnosis in 17 (60.7%). There was no major complication. A subgroup of patients was defined (persistent left lower lobe collapse or consolidation following thoracic or abdominal surgery) in whom fibreoptic bronchoscopy usually did not yield a useful outcome. Conclusion The use of fibreoptic bronchoscopy in the Intensive Care Unit, in combination with the technique of broncho-alveolar lavage, results in a clinically useful outcome in the majority of cases. Fibreoptic bronchoscopy is an effective and safe diagnostic and therapeutic tool in critically ill patients.

A Prospective Study

Background The determination of primary or secondary dengueinfection using hemagglutination inhibition (HI) test is time-con-suming. The IgG to IgM ratio which can be obtained earlier wasused by several studies to differentiate secondary from primaryinfection, but they still reported various cut-off points.Objective To find the diagnostic value and best cut off point ofIgG to IgM ratio for predicting secondary dengue infection.Methods This was a prospective study carried out between July2003 and June 2004. Children with suspected dengue hemor-rhagic fever (DHF) were tested for HI during acute and convales-cent phase. The IgG and IgM titer were examined during the acutephase using ELISA method.Results Sixty-two children were recruited, 48 with secondary in-fection and 14 with primary infection. The prevalence of second-ary infection was 77%. The best cut off point of the IgG to IgM ratioto predict secondary infection was >1.1 with sensitivity of 87.5%,specificity 92.9%, likelihood ratio 12.3, and post test probability97.7%.Conclusion The IgG to IgM ratio of >1.1 is a good predictor forsecondary infection

Established Technique

Abstract Background: Cryobiopsy is an established technique that yields larger and higher-quality samples than does a forceps biopsy. However, it remains underutilised in the diagnosis of peripheral pulmonary lesions (PPLs), mainly because of difficulties in handling conventional cryoprobes. A recently introduced single-use cryoprobe with a smaller diameter and more flexibility than conventional ones may improve its diagnostic ability for PPLs. We conducted this prospective study to evaluate the feasibility of transbronchial cryobiopsy in the diagnoses of PPLs, using a new 1.7-mm cryoprobe. Methods: The study included patients with PPLs less than 30 mm in diameter scheduled to undergo bronchoscopy. All the procedures were performed using a combination of virtual bronchoscopic navigation, radial endobronchial ultrasound (R-EBUS) and X-ray fluoroscopy, and all the samples were collected using the cryoprobe alone. Thereafter, we assessed the diagnostic outcomes and safety profiles.Results: A total of 50 patients were enrolled and underwent cryobiopsy. The median lesion size was 20.8 mm (range, 8.2–29.6 mm), and the negative bronchus sign was seen in 34% of lesions. The diagnostic yield was 94% (95% confidence interval, 83.5–98.8%). A positive bronchus sign had a significantly higher diagnostic yield than did a negative bronchus sign (100% vs. 82.4%; P=0.035). The yield was achieved regardless of other variables, including lesion size, location, and R-EBUS findings. The major complications were mild and moderate bleeding in 28% and 62% of patients, respectively. Pneumothorax was identified in one patient.Conclusion: Transbronchial cryobiopsy using the new 1.7-mm cryoprobe is a feasible procedure that has the potential to increase the diagnostic accuracy for PPLs.Trial Registration: Japan Registry of Clinical Trials, jRCT1032200065.
