ABSTRACT
Objective: To determine the diagnostic accuracy of x-ray chest in interstitial lung disease as confirmed by high resolution computed tomography [HRCT] chest
Study Design: A cross-sectional validational study
Place and Duration of Study: Department of Diagnostic Radiology, Combined Military Hospital Rawalpindi, from Oct 2013 to Apr 2014
Material and Method: A total of 137 patients with clinical suspicion of interstitial lung disease [ILD] aged 20-50 years of both genders were included in the study. Patients with h/o previous histopathological diagnosis, already taking treatment and pregnant females were excluded. All the patients had chest x-ray and then HRCT. The x-ray and HRCT findings were recorded as presence or absence of the ILD
Results: Mean age was 40.21 +/- 4.29 years. Out of 137 patients, 79 [57.66%] were males and 58 [42.34%] were females with male to female ratio of 1.36:1. Chest x-ray detected ILD in 80 [58.39%] patients, out of which, 72 [true positive] had ILD and 8 [false positive] had no ILD on HRCT. Overall sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of chest x-ray in diagnosing ILD was 80.0%, 82.98%, 90.0%, 68.42% and 81.02% respectively
Conclusion: This study concluded that chest x-ray is simple, non-invasive, economical and readily available alternative to HRCT with an acceptable diagnostic accuracy of 81% in the diagnosis of ILD
ABSTRACT
The three most common visual complications of preeclampsia and eclampsia are hypertensive retinopathy, exudative retinal detachment and cortical blindness. Preeclampsia-eclampsia can have neurological squelae; cortical blindness is one of these. We report case of parturient with mild preeclampsia that subsequently developed transient blindness
