Combined Factor VII and X Deficiency

Factor VII deficiency and factor X deficiency and very rare disorders individually. Combined Factor VII and X is a rare congenital blood disorder with very few cases reported in the literature. We report a case of 7 years old male child who presented to us as a diagnosed case of factor 7 deficiency with recurrent epistaxis

Respiratory Infection in Institutions during Early Stages of Pandemic (H1N1) 2009, Canada

Outbreaks of respiratory infection in institutions in Ontario, Canada were studied from April 20 to June 12, 2009, during the early stages of the emergence of influenza A pandemic (H1N1) 2009. Despite widespread presence of influenza in the general population, only 2 of 83 outbreaks evaluated by molecular methods were associated with pandemic (H1N1) 2009

Juvenile Nasopharyngeal Angiofibroma: Case report with review on role of imaging in diagnosis

Juvenile nasopharyngeal angiofibroma is a locally aggressive benign vascular neoplasm, composed of vasogenic and myofibroblastic elements, accounts for 0.05-0.5% of all the head and neck neoplasms. There are very few case reports of nasopharyngeal angiofibroma involving the oral cavity; we report a case involving both the maxilla and mandible in a 17-year-old patient who reported with a large firm swelling on right side of face with recurrent epistaxis and headache. Magnetic resonance angiography revealed a large lobulated enhancing soft tissue mass, which was hypointense on T1-weighted image and heterogeneously hyperintense on T2-weighted image causing expansion of pterygopalatine fossa and sphenopalatine foramen with extension into the sphenoid sinus, ethmoid air cells, right nasal cavity, right infratemporal fossa and right maxillary sinus with remodeling of right zygomatic arch and part of body and ramus of mandible. It was supplied by the right external carotid artery. Patient was referred to the department of neurosurgery for further management. The diagnosis at an early stage is important because it is associated with high risk of morbidity, but advances in imaging, and surgical methods of treatment have changed the sites associated with high risk of morbidity

Evaluation of <i>Salmonella</i> Typhimurium biofilm against some antibiotics

562-567Salmonella is an important bacterium causing diseases that affect humans and animals. Biofilm is an organized bacterial community dwelling in any ecosystem. Microorganisms which grow as biofilm phenotypes are cause of chronic, recurrent and highly antibiotic resistant infections which are difficult to eradicate. In the present study, Salmonella Typhimurium was incubated in various media (BHI, RV, NB, TSB and LB) along with various substrates (chitin, glass wool and plastic chips) to observe its ability to form biofilm. From the study, it was observed that S.Typhimurium successfully produced biofilm in all the media tested and was produced maximally when added with 1% chitin. The biofilm developed was exposed to the enzyme cellulase and it indicated that cellulase was having inhibitory effect on the biofilm. Biofilm and the normal phenotype were exposed to various antibiotics viz., amikacin, gentamicin, tetracycline and streptomycin and it was observed that increased concentration of antibiotics were required to completely inhibit biofilm when compared with the bacterium. However, antibiotics such as enrofloxacin and chloramphenicol inhibited biofilm phenotype and the bacteria at similar concentrations

The genome trilogy of Anopheles stephensi, an urban malaria vector, reveals structure of a locus associated with adaptation to environmental heterogeneity.

Anopheles stephensi is the most menacing malaria vector to watch for in newly urbanising parts of the world. Its fitness is reported to be a direct consequence of the vector adapting to laying eggs in over-head water tanks with street-side water puddles polluted by oil and sewage. Large frequent inversions in the genome of malaria vectors are implicated in adaptation. We report the genome assembly of a strain of An. stephensi of the type-form, collected from a construction site from Chennai (IndCh) in 2016. The genome reported here with a L50 of 4, completes the trilogy of high-resolution genomes of strains with respect to a 16.5 Mbp 2Rb genotype in An. stephensi known to be associated with adaptation to environmental heterogeneity. Unlike the reported genomes of two other strains, STE2 (2R+b/2Rb) and UCI (2Rb/2Rb), IndCh is found to be homozygous for the standard form (2R+b/2R+b). Comparative genome analysis revealed base-level details of the breakpoints and allowed extraction of 22,650 segregating SNPs for typing this inversion in populations. Whole genome sequencing of 82 individual mosquitoes from diverse geographical locations reveal that one third of both wild and laboratory populations maintain the heterozygous genotype of 2Rb. The large number of SNPs can be tailored to 1740 exonic SNPs enabling genotyping directly from transcriptome sequencing. The genome trilogy approach accelerated the study of fine structure and typing of an important inversion in An. stephensi, putting the genome resources for this understudied species on par with the extensively studied malaria vector, Anopheles gambiae. We argue that the IndCh genome is relevant for field translation work compared to those reported earlier by showing that individuals from diverse geographical locations cluster with IndCh, pointing to significant convergence resulting from travel and commerce between cities, perhaps, contributing to the survival of the fittest strain
