    Abstract Due to the increase in urbanization and industrialization, the load of toxicants in the environment is alarming. The most common toxicants, including heavy metals and metalloids such as hexavalent Chromium, have severe pathophysiological impacts on humans and other aquatic biotas. Therefore, developing a portable rapid detection device for such toxicants in the aquatic environment is necessary. This work portrays the development of a field-portable image analysis device coupled with 3,3',5,5'-tetramethylbenzidine (TMB) as a sensing probe for chromium (VI) detection in the aquatic ecosystem. Sensor parameters, such as reagent concentration, reaction time, etc., were optimized for the sensor development and validation using a commercial UV-Vis spectrophotometer. The chemoreceptor integrated with a uniform illumination imaging system (UIIS) revealed the system's applicability toward Cr(VI) detection. The calibration curve using the R-value of image parameters allows Cr(VI) detection in the linear range of 25 to 600 ppb, which covers the prescribed permissible limit by various regulatory authorities. Furthermore, the adjusted R2 = 0.992 of the linear fit and correlation coefficients of 0.99018 against the spectrophotometric method signifies the suitability of the developed system. This TMB-coupled field-portable sensing system is the first-ever reported image analysis-based technology for detecting a wide range of Cr(VI) in aquatic ecosystems to our knowledge.

    Abstract Context: Fertility rates have started declining in West Bengal, India in the last few decades. In vitro fertilization (IVF) is one of the major treatment modalities available to infertile couple. Aims: This study was aimed to evaluate and compare the growth parameters of IVF and spontaneously conceived children. The objective of this study is to relate the physical status of IVF children with that of spontaneously conceived group. Settings and Design: In a cross-sectional case-control study, growth parameters of 3-14-year-old children were assessed. Subjects and Methods: Weight and height of 3-14-year-old children were assessed. Birth weight and length of each case and control group was also recorded. The case group consisted of term, singleton babies who were outcome of IVF in the studied area in 2009. The control group consisted of term, first child, singleton, and spontaneously conceived 3-14-year-old children who were also resident of the studied area. A sample of 150 IVF and 150 spontaneously conceived children were examined. Statistical Analysis Used: Chi-square and student′s t-test were used for data analysis. Results: No statistically significant difference found in the studied (IVF children) and the control group (spontaneously conceived children). Conclusions: Growth retardation is more prevalent in babies born through IVF in the initial phase of life, but later on, IVF children are considered same as spontaneously conceived children.

    Abstract Introduction: Developmental defects of the enamel (D.D.E.) are changes in the deciduous dentition may lead to aesthetic problems, dental sensitivity and may be predictors of dental caries. The aim of this study was to estimate the prevalence and distribution of D.D.E. in the deciduous dentition of IVF children of West Bengal. Materials and Methods: A cross-sectional study was carried out with a sample of 153 IVF children aged three to five enrolled in institute of reproductive medicine Kolkata, West Bengal, India. One hundred fifty three spontaneously conceived matched controlled children also examined as control group. All of the teeth were examined and the enamel defects were assessed according to the Modified D.D.E Index. The differences were tested for statistical significance by using the Chi-Square test & z-test. Results: The prevalence of D.D.E. was 7.18% in IVF Children and 8.49% in spontaneously conceived children. Diffuse opacities was the common defect found (2.61%) in both group. The most affected teeth were the deciduous maxillary central incisors (12.82% and 13.63% found in IVF and spontaneously conceived group respectively). Defects were observed more frequently in the maxillary arch than in mandibular arch in both groups. Conclusion: There is no significant difference found in IVF & spontaneously conceived children group.

    Abstract Context: Santal is the third largest tribal community of India leading a very poor standard of education and life style. There are, however, few population-based studies evaluating the oral health status among Santal children in West Bengal. Aims: The aim of the study was to evaluate the oral health status of Santal children of West Bengal by assessing prevalence of dental caries and inflammatory condition of gingival. Settings and Design: Santal children aged between 2-14 years (N = 1205) were randomly selected from different Santal communities of West Bengal for this study. The children were divided into three different groups according to dentition. Materials and Methods: Caries for permanent dentition Decayed Missing Filled Tooth (DMFT), for deciduous dentition decayed extracted filled (def index was used. For mixed dentition DMF and def was measured respectively and then added together. Inflammatory condition of gingival was assessed by papillary marginal attachment (PMA) index. Statistical Analysis Used: the data was analyzed statistically by SPSS software version 11. Results: The study showed there was no significant difference (P > 0.05) between the average decayed extracted filled teeth (deft)/DMFT for boys and girls in deciduous and permanent dentition. But in mixed dentition this value for the boys was significantly higher (P < 0.001) than girls. ′Z′ values were found to be non significant when compared mild, moderate and severe gingivitis between boys and girls in each dentition group, but mild gingivitis significantly increases from deciduous dentition to mixed to permanent dentition (P <0.001).

    Abstract Addison′s disease is a rare endocrinal disorder, with several oral and systemic manifestations. A variety of pathological processes may cause Addison′s disease. Classically, hyperpigmentation is associated with the disease, and intraoral pigmentation is perceived as the initial sign and develops earlier than the dermatological pigmentation. The symptoms of the disease usually progress slowly and an event of illness or accident can make the condition worse and may lead to a life-threatening crisis. In this case, several oral as well as systemic manifestation of the Addison′s disease was encountered.

    Abstract Context: Dermatoglyphic is the permanent imprint found in hands. Variations of dermatoglyphic patterns among the individuals have been noted. Aims: To find out the dermatoglyphic pattern variations in dental caries between study group and the control group. Settings and Design: A cross-sectional study was done on 300 Bengalee children of Kolkata between the age group of 4-14 years. Materials and Methods: The samples were divided into two groups; study group and control group. Dental caries were detected clinically using mouth mirror and probe in daylight. Ink was applied on palm and finger by pressure pad. Bilateral palm and finger prints were taken by placing the palm and fingers over glazed paper and applying pressure over palm. Finger and palm prints obtained were inspected by magnifying glass for the study of different dermatoglyphic parameters. Statistical analysis used: Analytical statistical method with the help of student′s t-test was used to determine mean values and gender differences in the findings using SPSS version 11.0. Results: The characteristic feature which shows significant increase in caries sample group were increased total finger ridge count (TRFC) and absolute finger ridge count (AFRC) on fingers, representing pattern size and types. ab count and tr count were significantly lower in male and female caries sample group compared with the control group. Conclusions: There was a significant difference between caries and control group in different patterns and number of "tri radii on fingers" in fingers, the percentage of patterns on all palmar areas, total number of triradii on palm and main line index. Perhaps more systematic larger samples consisting of different genetic population are necessary to verify the conclusion.
