ABSTRACT
Background:Community-acquired pneumonia (CAP) is a leading cause of morbidity and mortality worldwide. Despite advanced diagnostic modalities and treatment options, CAP is the fourth leading cause of death in developing countries.Several severity scores have been proposed to guide initial decision making on hospitalization and to predict the outcome. Pneumonia Severity Index (PSI) and CURB 65 are the two most widely used scoring systems to prognosticate pneumonia. Aim: To compare the efficacy of PSI and CURB 65 scoring systems inprognosticating the ICU admission and outcome in cases of CAP. Methodology: This wasan observational study conducted at a tertiary care hospital in westernMaharashtra.A hundred patients of CAP fulfilling the inclusion criteria were enrolled in the study, classified as per CURB 65 and PSI system and their outcome compared. Result: The study subjects comprised of 100 patients (64 men and 36 women) of CAP. Twenty-four patients needed ICU admission.In both PSI and CURB-65 risk scoring systems, the need for intensive care unit (ICU) admission and mortality rates increased progressively with increasing scores.PSI class ≥IV and CURB 65 ≥III had 77.52% and 40.24% sensitivity and 88.46% and 69.48% specificity respectively in predicting ICU admissions. The PSI class ≥IV had more sensitivity and specificity in predicting ICU admission than CURB-65.CURB 65 class III and IV had sensitivity86.59% and 89.64% and specificity 89.64% and 97.54% respectivelyin predicting mortality, while PSI class IV and Vhadsensitivity68.92% and 72.58% and specificity 24.74% and 54.86% respectively. CURB 65 had more sensitivity and specificity than PSI in predicting mortality. Conclusion: The PSI is better in predicting the need for ICU admission and CURB 65 is a better predictor of mortality in cases of community-acquired pneumonia.
ABSTRACT
Creutzfeldt-Jakob Disease (CJD) is a rare invariably fatal neurodegenerative disease believed to be caused by an abnormal isoform of cellular infectious glycoprotein called prion protein. Though it is arare disease; yet it is the most common among prion diseases. Clinical presentation consists of rapidly progressive loss of memory, cognitive & visual disturbance, lack of coordination, myoclonus, cerebellar, pyramidal and extra pyramidal signs, akineticmutism & with progression of disease deterioration in higher mental functions become more pronounced. Periodic sharp triphasic wave complexes on EEG, high signal abnormalities in caudate nucleus and putamen on diffusion weighted (DW) or FLAIR MRI of Brain and positive 14-3-3 protein in CSF substantiate the diagnosis of CJD but definitive diagnosis is established by brain biopsy or autopsy materials. We report a case of 58-year old female patient who was admitted with complaints of rapidly progressive dementia, cognitive disturbance, blurring of vision and myoclonic jerks. Initial MRI brain and CSF findings were normal. Differential diagnoses that can present with rapidly progressive dementia and thereby mimic sporadic Creutzfeldt-Jakob disease were considered after review of literature. In EEG triphasic wave complexes were seen, repeat DWMRI after two weeks showed bilateral hyper-intensities in basal ganglia involving caudate nucleus and putamen, suggesting a diagnosis of probable CJD on the basis of center for disease control and prevention (CDC) criteria. The case is reported because of its rarity and also to emphasise that patients with rapidly progressive dementia, associated visual and cognitive disturbances and myoclonus should be investigated with DW MRI, EEG&CSF for diagnosis of CJD.
