Introduction: Lateral cephalograms display numerous cranial, facial and oral anatomic structures along with sella turcica which is considered vital for many radiographic analyses. It is demarcated by dense thin white line and is used to measure the position of maxilla & mandible in relation to the cranial base and to themselves. Various studies have found an association between morphological variations of sella to malocclusion and also gender differences have been noted. This retrospective study was carried out to evaluate these morphological variations of sella turcica and its relation to type of malocclusion. Aim: To determine dimensions and morphological variations of sella turcica in different age groups & correlation between sella and type of malocclusion. Materials And Methods: 200 lateral cephalometric images of the patients more than age group of 8 years and less than 25 years were selected. The morphological variations, linear measurements of sella turcica and the skeletal type classification, based on ANB angle was determined. Length, depth, antero-posterior diameter (linear dimentions) were measured and correlated with the type of malocclusion. Results: Out of the total sample studied, it was found that, when linear measurements were assessed, there was statistically significant difference found between the length and antero-posterior diameter of sella turcica. When skeletal type malocclusion was assessed, there was no significant correlation found between sella morphology, linear dimensions and the different types of malocclusion. Conclusion: The study showed significant correlation between the length and the anteroposterior diameter with the advancing age which signifies that growth of the individual can be assessed based on the size of sella turcica at different age periods.

The term “Metabolic Syndrome” has become widely used since its inception in 2001 by the NCEPATPIII, the concept of “clustering” metabolic disorders and Cardiovascular Disease (CVD) risk factors has been discussed in the scientific literature for many decades. The highest recorded prevalence worldwide is in Native Americans, with nearly 60% of women ages 45–49 and 45% of men ages 45–49 meeting NCEP:ATPIII criteria. Prevalence of the metabolic syndrome ranges from about 11 to 41 per cent in different regions of India. The present study is a one year cross sectional study that aims to study the prevalence of metabolic syndrome in patients with acute myocardial infarction and to assess and analyse the prevalence of individual components of metabolic syndrome in patients with acute myocardial infarction & also its impact on the prognosis of patients with acute myocardial infarction during one week of in-hospital stay, admitted to Rajendra Institute of Medical Sciences , Ranchi. Data was collected during their hospital stay & descriptive statistical analysis ,.Test of proportion, Chi-square ( 2 ) Odds Ratio (OR) with 95% confidence limit were used for statistical analysis. The prevalence of metabolic syndrome in acute MI in our study (49.2 %). .The body mass index (BMI) of> 25 kg/m 2 was found to be present in 84.6 % of patients with metabolic syndrome. Serum Triglycerides was found to be higher in our study compared to other studies. The mean values of HDL-C and Waist Circumference (WC) were found to be lower in our study compared to other studies. .Among the components of metabolic syndrome, low HDL-C was the most prevalent component among Metabolic syndrome patients .Development of complications (heart failure, arrythmias, re-infarction and case mortality) was significantly higher in patients of metabolic syndrome compared to those without metabolic syndrome.

The clinical appearance of leg ulcers is an important factor in the clinical assessment of healing progress. Digital imaging techniques, being objective and reproducible, have advantages over human assessment of wounds. In this cross-sectional, prospective study, conducted in a teaching hospital in Western India, images of 45 chronic leg ulcers were obtained using a digital camera to objectively analyze ulcer images with the help a software system. The clinical state of ulcers was documented by a wound score by the first observer and the readings of Red-Yellow-Black-Pink components of the ulcer-images were taken using ImageJ software by the second observer. The data were analyzed using appropriate statistical tests. The leg ulcers were classified clinically into four categories: Healing, Inflamed, Slough and Necrotic, as per Applied Wound Management assessment tool. The clinical score and Red-Yellow-Black-Pink colour analysis using ImageJ were obtained. The inter-rater analysis using linear weighted kappa (K) was highly significant (K=0.833; 95% CI: 0.709 to 0.957), indicating excellent agreement. The results from this pilot study suggest that digital imaging technique has the potential to objectively process digital images of chronic ulcers.

Matrices are used whenever one or more walls of the tooth are missing. They help to establish the proper anatomic contour and proximal contacts without gingival overhangs. There are several designs of matrices available for different clinical situations. They may range from a simple metal or plastic strip to a circumferential band of metal encircling the entire crown depending on the extent of tooth destruction.

Background: Fine needle aspiration cytology (FNAC) is the first choice for evaluation of thyroid enlargement. Diagnosis is based on the identification of predominant cell pattern, cell morphology and background details. Fine needle non-aspiration cytology (FNNAC) avoids aspiration, uses capillary action of the fine needle. It is more patient friendly with less pain and better perception of lesion. Aim of the study: To evaluate the results ofFine Needle Aspiration Cytology (FNAC) and Fine Needle Non Aspiration Cytology (FNNAC) in diagnosis of thyroid lesions. Materials and Methods: One-year observational, prospective study was conducted on patients with palpable thyroid lesions in the Department of Pathology, Government Medical College, Jammu. Patients were investigated with a thyroid function test and a needle biopsy. Both FNAC and FNNAC techniques were performed simultaneously at the same site by the same investigator. Points were allocated to each specimen according to Mair et al. scoring system and categorized as follows: unsuitable for cytodiagnosis (0-2 points), diagnostically adequate (3-6 points) and diagnostically superior (7-10 points). Results: A total of 140 patients with palpable thyroid lesions were subjected to needle biopsies. Females dominated the study with female to male ratio of 5.36:1. Non-neoplastic lesions were observed in 89.29% and neoplastic in 10.71% cases. . The cumulative score was found significantly more in case of FNNAC than FNAC (946 vs 784; p<0.0001). For diagnostically superior category, results of both FNAC and FNNAC were comparable. Conclusion: FNAC smears produced adequate results in more cases. FNNAC was more diagnostically superior. It causes less damage to tissue, less artefacts and allows better perception of lesion. FNNAC is a good technique that should be used alone or in combination with FNAC for better diagnostic yield.
背景:细针穿刺细胞学检查(FNAC)是评估甲状腺肿大的首选方法。诊断是基于显性细胞模式，细胞形态和背景细节的识别。细针非抽吸细胞学(FNNAC)避免抽吸，利用细针的毛细管作用。它对病人更友好，疼痛更少，病变感觉更好。目的:探讨细针穿刺细胞学(FNAC)与细针非穿刺细胞学(FNNAC)在甲状腺病变诊断中的价值。材料与方法:对查谟政府医学院病理科可触及甲状腺病变患者进行为期一年的观察性前瞻性研究。对患者进行甲状腺功能检查和穿刺活检。FNAC和FNNAC技术由同一研究者在同一部位同时进行。根据maair等评分系统对每个标本进行评分，分为不适合细胞诊断(0-2分)、诊断适宜(3-6分)和诊断优良(7-10分)。结果:140例可触及甲状腺病变患者行针活检。以女性为主，男女比例为5.36:1。非肿瘤性病变占89.29%，肿瘤性病变占10.71%。FNNAC的累积得分明显高于FNAC (946 vs 784;p < 0.0001)。对于诊断优势类别，FNAC和FNNAC的结果具有可比性。结论:FNAC涂片在更多病例中获得了足够的结果。FNNAC在诊断上更优越。它对组织造成的损伤更小，人工制品更少，并且可以更好地感知病变。FNNAC是一种很好的技术，可单独使用或与FNAC联合使用，以提高诊断率。

Since ancient period, river sand has been used in the construction industry as a dominant material from the level of foundation to the end of a project .Today demand for sand continues to increase to meet the needs of growth in population. Excessive instream sand mining causes the degradation of rivers and creating ecological imbalance. Instream mining lowers the stream bottom, which may lead to bank erosion and may lead for river meandering. It is the need of the hour to investigate for a suitable alternative material for sand like stone crusher powder and granite fines etc. which are available abundantly from crusher units and granite industries. Use of stone crusher powder proves to be economical and eco-friendly which generally considered as unused. The investigations indicate that stone crusher powder has the similar characteristics and performances as that of river sand. In this paper an attempt has been made to investigate the replacement of sand with Stone crusher powder. Strength behavior of concrete with the use of stone crusher powder as a replacement of fine aggregates in different proportions is discussed. Test results are also discussed pertaining to strength and values are compared with conventional concrete.

Introduction: The anatomic location of the mental foramen is still a matter of debate. There are variations in the position of mental foramen in different populations. These variations indicate accurate detection of mental foramen position which result in safer dental procedures. Aim: To carry out a morphometric assessment of the mental foramen in patients with different facial types. Material and Methods:Ninety computerized cone beam tomographic scans from brachycephalic (n=30), dolicocephalic (n=30) and mesocephalic (n=30) facial types were used. Computerized cone beam tomographic scans were obtained using a Tomographic I Cat Unit and the Dolphin Imaging 11.0 Program. The mental foramen position was evaluated and compared in the three subgroups. The Bartlett and Shapiro-Wilk ́s tests were used to evaluate the homogeneity of the variances. Influence of the three facial types on cephalometric measurements was evaluated using two way ANOVA and Tukey ́s test. Correlationsbetweenage and some measurements of interest were assessed using Pearson ́s moment correlation test Results:Mental foramen height was slightly smaller in females. Facial types influenced the following measurements: distance from the apex of the second lower bicuspid to the upper border of the mental foramen and distance from the lower border of the mental foramen to thelower border of the mandible. Statistical differences were observed betweenmesocephalic and brachycephalic subjects (p<0.05) and between mesocephalic and dolicocephalic ones (p<0.05). Mental foramen height was smaller in mesocephalic subjects (p<0.05). Mental foramenwidthwas smaller only in the left side in mesocephalic subjects. Distance between the buccal cortical and lingual cortical of the mental foramen was smaller in mesocephalic than in brachycephalic and dolicephalic subjects (p<0.05). A higher number of mental foramina were positioned between bicuspids and along the long axis of the second bicuspids: 74% and 20% respectively. An oval mental foramen was found more frequently: (80.6%) in mesocephalics; (77.4%) in brachycephalics and (86%) in dolicocephalics subjects. A circular shape was observed in 19%; 22%; and 13% in mesocephalic, brachycephalic and dolicocephalic individuals, respectively. Conclusion: Some measurements of the mental foramen may be different among facial type subjects. Distribution and shape of the mental foramen are similar in the three facial types.
前言:颏孔的解剖位置仍然是一个有争议的问题。不同人群的脑孔位置存在差异。这些变化表明准确的检测精神孔的位置，导致更安全的牙科手术。目的:对不同面部类型患者的颏孔进行形态计量学评价。材料和方法:使用90个计算机锥形束断层扫描，分别来自短头型(n=30)、多头型(n=30)和中头型(n=30)面部类型。计算机锥形束断层扫描使用断层扫描I Cat单元和海豚成像11.0程序。评估并比较三个亚组的颏孔位置。采用Bartlett和Shapiro-Wilk检验来评价方差的同质性。采用双因素方差分析(two - way ANOVA)和Tukey’s检验评估三种面部类型对头颅测量的影响。使用Pearson′s矩相关检验评估年龄与某些感兴趣的测量值之间的相关性。结果:女性的心理孔高度略小。面部类型影响以下测量:从第二下二尖尖到颏孔上边界的距离和颏孔下边界到下颌骨下边界的距离。中脑组与短头组、中脑组与单头组间差异有统计学意义(p<0.05)。中脑组脑孔高度较低(p<0.05)。中脑受试者的精神孔宽度仅在左侧较小。中脑患者颏孔颊皮质与舌皮质之间的距离小于短头和头头患者(p<0.05)。较多的精神孔位于二尖瓣之间和沿第二二尖瓣的长轴，分别占74%和20%。卵圆形精神孔多见于中脑室(80.6%);(77.4%)，多头症患者(86%)。圆形的占19%;22%;中头、短头和多头分别为13%。结论:颅孔的某些测量值在面部型被试中可能存在差异。三种面部类型的颏孔分布和形状相似。

There are variations in the position of mental foramen in different populations. These variations indicate accurate detection of mental foramen position which result in safer dental procedures. Aim: To carry out a morphometric assessment of the mental foramen in patients with different facial types. Material and Methods:Ninety computerized cone beam tomographic scans from brachycephalic (n=30), dolicocephalic (n=30) and mesocephalic (n=30) facial types were used. Computerized cone beam tomographic scans were obtained using a Tomographic I Cat Unit and the Dolphin Imaging 11.0 Program. The mental foramen position was evaluated and compared in the three subgroups. The Bartlett and Shapiro-Wilk ́s tests were used to evaluate the homogeneity of the variances. Influence of the three facial types on cephalometric measurements was evaluated using two way ANOVA and Tukey ́s test. Correlationsbetweenage and some measurements of interest were assessed using Pearson ́s moment correlation test Results:Mental foramen height was slightly smaller in females. Facial types influenced the following measurements: distance from the apex of the second lower bicuspid to the upper border of the mental foramen and distance from the lower border of the mental foramen to thelower border of the mandible. Statistical differences were observed betweenmesocephalic and brachycephalic subjects (p<0.05) and between mesocephalic and dolicocephalic ones (p<0.05). Mental foramen height was smaller in mesocephalic subjects (p<0.05). Mental foramenwidthwas smaller only in the left side in mesocephalic subjects. Distance between the buccal cortical and lingual cortical of the mental foramen was smaller in mesocephalic than in brachycephalic and dolicephalic subjects (p<0.05). A higher number of mental foramina were positioned between bicuspids and along the long axis of the second bicuspids: 74% and 20% respectively. An oval mental foramen was found more frequently: (80.6%) in mesocephalics; (77.4%) in brachycephalics and (86%) in dolicocephalics subjects. A circular shape was observed in 19%; 22%; and 13% in mesocephalic, brachycephalic and dolicocephalic individuals, respectively. Conclusion: Some measurements of the mental foramen may be different among facial type subjects. Distribution and shape of the mental foramen are similar in the three facial types.","PeriodicalId":14489,"journal":{"name":"IOSR Journal of Dental and Medical Sciences","volume":"19 1","pages":"78-85"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74233400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
