Objective: To detect and compare serum lipid abnormalities in patients diagnosed with different grades of non-alcoholic fatty liver on ultrasonography. Methods: A total of 70 cases which included 30 males and 40 females, diagnosed as non-alcoholic fatty liver disease (NAFLD) on ultrasound were investigated with serum lipid profile. Then a comparison of lipid abnormalities between different grades of fatty liver diagnosed on ultrasound was done. P value was calculated by using analysis of variance test (ANOVA) and P value <0.05 was considered as statistically significant. Results: Out of 70 cases which were diagnosed as NAFLD on ultrasonography, grade I NAFLD cases were 47.15%, grade II were 42.85% and grade III were 10%. The mean age of the patients was 49.14 years. Male to female ratio was 3:4. Serum triglycerides, total cholesterol, LDL and VLDL levels were raised in 67.14%, 45.71% 34.28%, 25.71% of cases respectively. Low serum HDL levels were seen in 62.85% of patients. On statistical analysis we found increasing grades of NAFLD were significantly associated with increasing values of total cholesterol (P value-0.001), LDL (P value-0.000) and VLDL (P value-0.003) and decreasing HDL (P value-0.000). Conclusion: Most of the patients of NAFLD in India is asymptomatic, non-diabetic and non-hypertensive. Though liver biopsy is the gold standard method for diagnosis of NAFLD, Ultrasonography which is non-invasive, simple tool, can be used for the early detection of NAFLD in asymptomatic patients. © 2013 Asian Pacific Tropical Biomedical Magazine.

The aerobic microflora of the oral cavity consists of viridians group of streptococci (VGS). The present study was carried out with an objective to evaluate the prevalence of VGS in patients undergoing tooth extraction and to study their antibiotic susceptibility pattern. Samples of subgingival dental plaques for microbiological studies were collected from 80 patients undergoing tooth extraction. The isolated streptococci were identified along with their antibacterial susceptibilities by automated Vitek 2 (bioMérieux) system in accordance with CLSI standards. A total of 260 VGS strains belonging to 05 phenotypic groups, namely mutans, salivarius, anginosus, sanguinus and mitis groups; along with few strains of Granulicatella like G. adiacens and G. elegans. Altogether a total of 15 species were isolated from the subgingival plaque of 80 patients undergoing tooth extraction. Among the 15 antibiotics tested, highest resistance was observed to lincosamides (36.2%) followed by macrolides (29.7%), tetracyclines (17.7%), cephems (15.1%), fluoroquinolones (14.4%), oxazolidinones (13.5%), streptogramins (12.7 %) and penicillins (7.9%). However, all the 260 VGS strains were found susceptible to vancomycin and linezolid. In the subgingival plaque of patients undergoing tooth extraction, approximately 70% of streptococci belonged to three VGS groups, i.e. mitis, sanguinis and mutans groups. Streptococci of salivarus and anginosus groups were isolated sporadically (5%). Highest resistance was observed to lincosamides and macrolides (29.7%). Multiple antibiotic resistance was observed in mitis and salivarius group. © 2015, TIP ARASTIRMALARI DERNEGI. All rights reserved.

Context: The genus Streptococcus consists of more than 65 species. The taxonomic classification of these members is not well-defined. Among the viridans group streptococci (VGS), there are major taxonomic changes by the addition of many new species; whereas, most of the new strains are of animal origin and only a few have been reported to be isolated from humans. Rare and unusual species of VGS such as Streptococcus thoraltensis, S. pluranimalium and S. hyointestinalis are normally associated with different animals. Their isolation from human being is not yet reported. Aim: To find out the rare and unusual species of viridans group streptococci from human oral cavity. Settings and Design: A case-controlled study carried out at hospital-based dental services in a tertiary care hospital. Materials and Methods: Subgingival plaque samples of the tooth were collected from 80 patients (34 with periodontitis and 46 without periodontitis) undergoing tooth extraction. Cultures were subcultured onto special media such as Tryptone Soya blood Agar supplemented with strepto supplement and Mutans-Sanguis Agar. Identification of strains and antimicrobial susceptibilities were measured as minimum inhibitory concentration using Vitek 2 (BioMérieux, Paris, France) automated system. Results: We have identified three strains of VGS - S. thoraltensis, S. pluranimalium and S. hyointestinalis from subgingival plaque samples from patients with periodontitis. S. thoraltensis and S. pluranimalium were found to be resistant to most of the antibiotics. Conclusions: To the best of our knowledge, this is the first report of isolation of these rare and unusual strains from the human oral cavity. © 2016 Indian Journal of Pathology and Microbiology.

Bone-marrow derived stem cells are multi potential or totipotent and are able to differentiate into numerous cell types. Their application is indicated in various reconstructive and restorative surgeries for rapid healing. A technique for creating cells that have the embryonic ability to turn into almost any cell type in the mammalian body has been reported. Recently, an unexpected phenomenon of somatic cell reprogramming into pluripotent cells by exposing to sublethal stimuli such as citrate based acidic medium has been reported. With the concept of creating acidic environment in chronic infected wounds to make a condition unsuitable for growth and multiplication of bacteria using 3% citric acid has been reported. It would be interesting to study whether the phenomenon of pluripotency takes place in chronic infected wounds in human beings following the application of 3% citric acid and plays an important role in formation of healthy granulation tissue. © Journal of Krishna Institute of Medical Sciences University.

Streptococcus tigurinus is a new member of the Streptococcus viridians group and is closely related to Streptococcus mitis, Streptococcus pneumoniae, Streptococcus pseudopneumoniae, Streptococcus oralis, and Streptococcus infantis. The type strain AZ_3aT of S. tigurinus was originally isolated from a patient with infective endocarditis. Accurate identification of S. tigurinus is facilitated only by newer molecular methods like 16S rRNA gene analysis. During the course of study on bacteraemia and infective endocarditis with reference to periodontitis and viridians group of streptococci, a strain of S. tigurinus isolated from subgingival plaque of a patient with periodontitis identified by 16S rRNA gene analysis, which was originally identified as Streptococcus pluranimalium by Vitek 2. Confirmation by 16S rRNA gene analysis showed 99.39% similarity (1476/1485 bp) with S. tigurinus AZ_3aT(AORU01000002). To the best of our knowledge, this is the first report of isolation of S. tigurinus from the oral cavity of a periodontitis patient. © 2014 Federation of European Microbiological Societies.
