Amelogenesis Imperfecta: A Case Series from the Community

Amelogenesis Imperfecta is a hereditary disorder affecting the formation of enamel structure. Two female children and one male (11 years, 12 years and 6 years respectively) reported with chief complaint of yellowish discoloration of teeth since their childhood. They reported that they had similar discoloration in their deciduous teeth. Examination showed generalized deposits of plaque and calculus, yellowish discoloration of the teeth with chipping off of the incisal and cuspal enamel structures. OPG revealed thin lining of enamel with thick dentin layer and pulp chamber. PA view revealed unfused anterior fontanels and lateral cephalogram indicated vertebrae in growing phase. The patients were instructed to maintain proper oral hygiene and regular follow up till the growth cessation. Permanent skeletal, functional, esthetic needs is addressed after growth completion. Oral rehabilitation through multidisciplinary approach can certainly provide a good prognosis and patient was counseled and motivated to maintain good oral hygiene

Socioeconomic Indices as Independent Correlates of C-Reactive Protein in the National Longitudinal Study of Adolescent Health

Examine the association between SES and C-reactive protein (CRP) to understand how SES may increase the risk of CVD and thus identify targets for prevention measures

The Characterization of Twenty Sequenced Human Genomes

We present the analysis of twenty human genomes to evaluate the prospects for identifying rare functional variants that contribute to a phenotype of interest. We sequenced at high coverage ten “case” genomes from individuals with severe hemophilia A and ten “control” genomes. We summarize the number of genetic variants emerging from a study of this magnitude, and provide a proof of concept for the identification of rare and highly-penetrant functional variants by confirming that the cause of hemophilia A is easily recognizable in this data set. We also show that the number of novel single nucleotide variants (SNVs) discovered per genome seems to stabilize at about 144,000 new variants per genome, after the first 15 individuals have been sequenced. Finally, we find that, on average, each genome carries 165 homozygous protein-truncating or stop loss variants in genes representing a diverse set of pathways

Successful live birth after rescue ICSI following failed fertilization

In a conventional IVF cycle unexpected complete fertilization failure may occur in 10-25% of infertile women. To overcome this barrier of fertilization failure, some investigators have suggested intracytoplasmic sperm injection (ICSI) on day 1 of an unfertilized mature oocyte, the so called "rescue ICSI". We report a case of fertilization failure followed by rescue ICSI resulting in a live birth. Although the success of rescue ICSI is still questionable, this procedure is worth an attempt in order to give the best chance to the couple in that cycle

Effect of tobacco smoking on the periodontal health in Parsa, Nepal: A comparative cross-sectional study

Introduction: For ages, smoking tobacco has been a part of cultural practice in different parts of Nepal. For periodontal diseases, one of the important risk factors is tobacco smoking, mainly cigarette smoking. Objectives: This study was conducted to find out the relationship among tobacco smoking and periodontal disease by means of clinical attachment loss (CAL), plaque score, and gingival score in cigarette smoker patients in comparison with nonsmokers. Methodology: A comparative cross-sectional study was done among 300 patients who visited the Outpatient Department of Periodontics, M. B. Kedia Dental College, Parsa, Nepal. The patients were divided into two groups, cigarette smokers and nonsmokers. Oral cavity examination was done using plaque index, gingival index, and CAL. Mann–Whitney test was done to determine the relation between tobacco smoker and overall periodontal health. Results: The result shows that the overall median plaque score of the patients was 1.08, the gingival score of the patients was 1.22, and CAL was 2.04. Furthermore, there was statistical significance between periodontitis and cigarette smoking. Conclusion: The present study concluded that smoking has a negative effect on periodontium health. More duration of cigarette smoking habit had higher severity of symptoms when compared to nonsmokers

Predictive value of early serum beta-human chorionic gonadotrophin for the successful outcome in women undergoing in vitro fertilization

Aims: Pregnancies achieved by in vitro fertilization (IVF) are at increased risk of adverse outcome. The main objective of this study was to evaluate the predictive value of β-human chorionic gonadotrophin (β-HCG) and age of the patient for the successful outcome in IVF. Materials and Methods: A retrospective study was done in 139 pregnancies after IVF at single IVF center from June 2007 to July 2012. The age of the patient and initial serum values of β-HCG on day 14 of embryo transfer were correlated with ongoing pregnancy (>12 weeks gestation). Results: The β-HCG level on day 14 of more than 347 mIU/ml has a sensitivity of 72.2% and specificity of 73.6% in prediction of pregnancy beyond 12 weeks period of gestation. Positive likelihood ratio (LR) is 2.74 and negative LR is 0.37, (receiver operating characteristic area = 0.79). Discussion: In IVF cycles, there is a lot of stress on the couples while the cycle is going on. There was a positive correlation between the higher values of early serum β-HCG levels and ongoing pregnancy. Hence, it can be used as an independent predictor of a successful outcome of IVF cycle. Conclusion: We concluded from our study that early serum β-HCG can be used as a predictor of a successful outcome in IVF
