ABSTRACT
Objective: To evaluate the differences in the presentation, their operative implications and difficulties of single stone versus multiple gall stone disease.Methods: This is a prospective study of a minimum of 60 patients with gall stone disease (Group 1-single, Group 2-multiple) from January 2019 to December 2019 in KGH, Visakhapatnam.Results: More common in females, 40-50 years symptoms and complications, TC count difficult cholecystectomies were more in multiple gall stone pts.Conclusion: Multiple gall stones have led to more severe symptoms and complications and difficult surgery. should be motivated for early surgery even in incidental finding and should not opt for conservative management.
ABSTRACT
Background: Pneumococcal pneumonia is one of the major causes of mortality in children less than 5 years in Asia, especially in India. Available PCVs have less serotype coverage in India compared to western countries. Moreover, the baseline pneumococcal serotype and sequence type data is limited and available data doesn't represent the entire India. With this background we aimed to characterize invasive and carriage isolates of S. pneumoniae from a tertiary care hospital in South India. Materials and Methods: A total of 221 S. pneumoniae isolates, invasive (n=138) and carriage (n=83) between the time period of 2012-2018 were included. Isolates was identified and confirmed using standard laboratory protocols. Serotyping was performed by Customized sequential multiplex PCR and MLST as described in www.pubmlst.org. Results: The major serotypes were 19F, 6B, 14, 6A and 19A and the sequence types (ST) were ST63, 236 and 230. Predominant STs in invasive was ST 63 whereas in carriage were ST4894 and 1701. High level ST diversity in carriage was observed. Majority of the STs were SLVs or DLVs of previously reported STs or PMEN clones. Phylogenetic analyses of the STs revealed gradual expansion of three PMEN CCs CC320, 63 and 230. Conclusion: The vaccine serotypes were the predominant ones found to be associated with IPD, PMEN clones, new STs and antimicrobial resistance. Accordingly, PCV13 is expected to provide invasive serotype coverage of 75% in Indian children less than 5 years. This study provides baseline serotype and sequence type data prior to the introduction of PCV in South India.
ABSTRACT
Background & objectives: An increase in prevalence of atherosclerosis has been noted worldwide with reports of higher incidence of atherosclerotic vascular changes in Asian Indians. There is a need to measure vascular atherosclerotic changes and provide objective parameter to predict cardiac and cerebrovascular adverse events. Atherosclerotic changes in carotids and coronaries are generally accepted as an association. We attempted in this study to relate intimal-luminal changes in carotid arteries to luminal changes in coronary arteries. Our study presents results of high resolution ultra sonographic (HRUS) evaluation of intimal-medial-thickness (IMT) in carotid with luminal changes in coronaries on multidetector-CT (MDCT) in clinically asymptomatic and symptomatic individuals. Methods: In this prospective study, HRUS examination of the carotid bifurcation was performed in 151 individuals to measure IMT in asymptomatic and symptomatic groups. Assessments of coronary arteries of the same group of patients were evaluated by MDCT within a week interval. IMT changes were associated with age, sex, predisposing factors, calcium burden of coronaries and structural atherosclerotic changes in coronary arteries. Results: A linear association of IMT was observed with increasing age. IMT of 0.5-0.69 mm was noted in 50 per cent of patients between 51-56 yr with higher number of symptomatic patients in this group. Linear increases in coronary vascular changes were noted with increasing IMT thickness. Changes were more prevalent in diabetic, hypertensive, treadmill test (TMT) positive and clinically symptomatic patients. Interpretation & conclusions: Age-related progression of atherosclerosis was evident in internal carotid arteries. Significant association was observed in the IMT thickness of right common carotid (RCC) and coronary disease in symptomatic group; whereas IMT of left common carotid and internal carotid arteries did not show any association. RCC IMT between 0.5-0.7mm showed maximal association with significant symptomatic narrowing of coronary arteries. Patients with IMT beyond 0.7mm had no association with symptoms.
