We describe 2 cases of Mycobacterium massiliense infection after cardiac surgery. A 68-year-old man developed high-grade fever and sternal wound infection 5 weeks after aortic valve replacement. He was discharged after antibiotic treatment but readmitted with pseudoaneurysm of the aortic root. He succumbed to hemorrhage 2 weeks after reoperation. A 7-year-old boy developed endocarditis after atrial septal defect patch repair, and underwent replacement of the patch. Samples from both patients grew Mycobacterium massiliense.
Non-resolving pneumonia leading to lung abscess is always a challenge to the treating physician especially in a diabetic patient. Atypical radiological features of lung abscess should raise the suspicion of unusual organisms. This is a case report of a 42 year old diabetic male presented with features suggestive of lung abscess and multiple target organ damage. Subsequent work up revealed that the etiological agent is a rare fungus – Basidiobolus. To the best of our knowledge this is the first case of Basidiobolus lung abscess reported from India.
BackgroundCandida has been associated with cases of secondary and persistent root canal infections. The purpose of this study was to evaluate and compare the effectiveness of commonly used intracanal medicament against Candida biofilms found in root canals of human primary teeth with necrotic pulp.Materials and methodsPulp canals of 45 single-rooted primary maxillary anterior teeth with pulp necrosis in 34 children were included in the study. They were divided into three groups of 15 samples each - group I: Ca(OH)2 (calcium hydroxide); group II: 1% chlorhexidine gel (CHX); and group III: 1% metronidazole gel. Bacterial count was obtained from each tooth at two different stages: (1) after instrumentation, and (2) after placement of the medication. Statistical analysis using the Statistical Package for the Social Sciences version 10.0 software program (Inc., Chicago, IL, USA) with Wilcoxon signed rank test after grouping the samples was performed.ResultsCa(OH)2, 1% CHX gel, and 1% metronidazole gel were ineffective in completely eliminating Candida biofilms from root canal of human primary teeth with necrotic pulp.ConclusionNone of the commonly used intracanal medicaments, i.e., Ca(OH)2, 1% CHX gel, and 1% metronidazole gel, was effective in completely eliminating Candida biofilm from root canal of human primary teeth with necrotic pulp. Ineffectiveness of these medicaments against Candida has opened new door of research regarding the use of suitable intracanal medicaments against single and multispecies biofilms.How to cite this articlePaikkatt JV, Sreedharan S, Philomina B, Kannan VP, Santhakumar M, Kumar TVA.

Cholera outbreaks are prevalent in countries with a low Human Development Index (HDI) where people have limited access to safe drinking water, sanitation and hygiene (WASH). Intriguingly, the state of Kerala which records the highest HDI in India is endemic to cholera. We discuss the epidemiology of a cholera outbreak reported among migrant workers of Kerala in 2017. Virulence genes of Vibrio cholerae, toxR and ctxA, were detected in the river and ground water samples collected from the outbreaks sites which indicates need of enhanced awareness on WASH practices among migrant workers. The pathogenic Vibrio cholerae isolated from four patients in two districts had a similar DNA band pattern when analysed using repetitive extragenic palindromic-PCR (BOX), which indicates their single clonal origin. The four isolates were serotyped as O1 Ogawa. These isolates were resistant to multiple antibiotics including the carbapenem like imipenem. Nevertheless, isolates of these pathogenic bacteria were susceptible to tetracycline, identical to clinical isolates of Vibrio cholera reported earlier from this region. The current study highlights the importance of generating awareness on WASH protocols among migrant workers to prevent the outbreaks and considers community-based data as socioeconomic variable to predict the incidence of cholera.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
