Epidermolysis bullosa dystrophica with renal failure

Inherited epidermolysis bullosa (EB) is a family of diseases with blistering of skin and mucous membrane even with mild trauma. It has different subtypes based on the affected protein. Epidermolysis bullosa dystrophica (EBD) is associated with mutations in the COL7A1 gene encoding type VII collagen leading to the fragility of skin and mucosal membranes. EBD may be dominant or recessive. They should be distinguished because increased prevalence of SCC is associated with the recessive form. Here we are reporting a case at our hospital presented with various clinical features, history, clinical spectrum, renal biopsy and gene analysis giving appropriate diagnosis for the disorder. Treatment remains challenge. A multidisciplinary approach is needed for the effective management of EBD.

Dynamics of the occurrence of influenza in relation to seasonal variation in Chennai, Tamil Nadu: A 7 -year cumulative study

Background: Influenza viruses have emerged as virulent pathogens causing considerable burden across the world. A thorough understanding of the pattern in occurrence of influenza globally is the need of hour. The present study deals with analysis of the dynamics of Influenza virus, especially the influence of seasonal change on viral circulation and causation of epidemics/pandemics in the context of subtropical region. Methods: During the 7 year (2009–2015) study, 36670 specimens were subjected to influenza analysis. Nasopharyngeal swabs collected from suspected patients from Chennai, Tamil Nadu, were tested and typed by real-time polymerase chain reaction assay. Results: During 2009 pandemic, among influenza A positives 95.16% were Apdm09, indicating that there was a predominant circulation of Apdm09. During postpandemic period, there were waves in the occurrence of Apdm09 which indicates fall in immunity with buildup in the susceptible population. Conclusion: In Chennai, Tamil Nadu, influenza positivity started with the onset of monsoon and peaks during the postmonsoon months throughout the study period. The assessment of meteorological factors compounding influenza activity can help in raising alerts to the public health officials of impending disaster which suggests that Influenza vaccination can be initiated before monsoon months in South India.
