Biomimetics and the restoration of the endodontically treated tooth / Biomimética e a restauração do dente tratado endodonticamente

Although much progress has been obtained in terms of the Endodontic treatment, the literature shows that true success can be only achieved with adequate coronal seal to avoid bacterial contamination, and protect the tooth structure from fracture. There are many options available to the clinician to restore the endodontically treated tooth; however, there is not much evidence available on what alternative is better than another. This review will critically present the current knowledge on restorative choices, including posts and endocrowns, showing advantages and disadvantages of different treatment forms. With this knowledge, we will also introduce the concept of biomimetics to endodontically treated teeth, and how the nature of their remaining tooth structure can benefit from this approach. This concept entails the use of mechanisms and biologically produced materials to restore a tooth in a way that would mimic its natural structure, with the purpose of achieving better long-term prognosis (AU)

Embora tenha se obtido progresso em relação ao tratamento endodôntico, a literatura mostra que o sucesso real só pode ser atingido com o selamento coronal adequado, para evitar-se a contaminação bacteriana e proteger-se a estrutura dental de fraturas. Há muitas opções disponíveis para o clínico para a restauração do dente tratado endodonticamente; entretanto, não há muita evidência disponível sobre qual alternativa é melhor que a outra. Esta revisão apresentará criticamente o conhecimento atual sobre opções restauradoras, incluindo retentores intraradiculares e endocrowns, mostrando vantagens e desvantagens das diferentes formas de tratamento. Com esse conhecimento, também introduziremos o conceito de biomimética, uma vez que dentes tratados endodonticamente, devido a natureza de sua estrutura dental remanescente, podem se beneficiar desta abordagem. Esse conceito envolve o uso de mecanismos e materiais produzidos biologicamente para restaurar um dente de forma a imitar a estrutura natural, com o objetivo de alcançar melhor prognóstico de longo-prazo.(AU)

Optimizing Internet Use during Adolescence: eHealth Solutions

Internet offers an immense opportunity as a resource for education, training, and health promotion. This narrative review summarizes the opportunities for health promotion among adolescents through use of the Internet and technology (defined as eHealth). The details of technology and use of Internet for adolescent-health related topics such as nutrition, fitness, sexual health, adventure, and violence were searched through PubMed. The review reports few digital solutions to address key challenges during adolescence like promotion of nutrition and sexual reproductive health, prevention of noncommunicable diseases, substance abuse, and mental health issues. eHealth was concluded as a potential solution for preventive and promotional health practices during adolescence. However, concerns of Internet addiction, safety, privacy, mental health disorders, and misinformation need to be addressed and monitored during adolescence.

Role of Immunohistochemistry and serology in subclassifying the Inflammatory Bowel Disease cases diagnosed as Inflammatory Bowel Diseases-unclassified on colonic biopsies

Background: Inflammatory bowel diseases (IBDs) mainly consist of Crohn's Disease (CD) and Ulcerative Colitis (UC). These two categories have overlapping histopathological features and sometimes it is difficult to diagnose them into distinct category and such biopsies are categorised as Inflammatory Bowel Disease (IBD-U). Recently, there has been an increase in interest to discover new biomarkers of IBD to differentiate UC and CD and predict their prognosis. Method: In the present study, 273 non-neoplastic colonic biopsies with clinicoendoscopic features of IBD were studied and categorized into UC (88; 32.3%) and CD (03; 1.1%) but a major chunk remained in category of IBD-U (182; 66.6%). 161 (58.9%) of these biopsies were then subjected to IHC for RB protein and ?-catenin and Serology for pANCA and ASCA was done in only 85 (31.13%) of these selected cases for identification of UC and CD on colonic biopsies. Result: 161 biopsies that were subjected to IHC analysis included 57 cases of UC, 03 cases of CD, and rest 101 cases of IBD-U. Out of 101 cases of IBD-U, 87 (86.13%) cases were reclassified as UC (61; 60.3%) and CD (14; 13.86%) on the basis of results of IHC and Serology. Conclusion: The two major tools IHC for ?-catenin and RB protein and the assay of serum ASCA and p-ANCA along with proper history and clinical presentation can act as a good adjunct to conventional H and E in subclassifying cases of IBD-U into UC and CD.

Prevalence of precursor lesions (P53 signature, SCOUT, STIL, STIC) in fallopian tubes resected for non-neoplastic causes

Background: High-grade pelvic serous carcinoma is a common cause of death in women worldwide and India. Recent evidence has clearly implicated the changes in the mucosa of the fimbrial end of the fallopian tube in its pathogenesis. Objective: 1) To study histopathology features of surgically resected specimens of fallopian tubes received with non-neoplastic lesions of the uterus and ovary for the presence of any precursor lesions [secretory cell outgrowth (SCOUT), serous tubal intraepithelial lesion (STIL), p53 signatures, and serous tubal intraepithelial carcinoma (STIC)]. 2) To confirm the findings with immunohistochemistry. 3) To correlate the prevalence of precursor lesions with clinical parameters and benign lesions of the uterus and ovaries. Materials and Methods: Assessment of histopathological changes in 100 specimens of distal fallopian tubes was done using the sectioning and extensive examination of the fimbrial end (SEE-FIM) protocol. H and E stain followed by immunohistochemistry for Bcl-2, p53, and Ki-67. The statistical significance of the difference in the mean values of precursor areas was evaluated by an unpaired t-test. Results: Among 100 specimens taken on H and E, precursor lesions were suspected in 49% of the cases. SCOUT, suspicious for STIC, suspicious for STIC with areas of SCOUT, and unequivocal for STIC with areas of SCOUT were seen in 8%, 4%, 33%, and 4% of the cases, respectively. However, on IHC, SCOUTS were confirmed in 45% of the cases, p53 signature in 2%, STIL in 9%, and STIC in 4% of the cases. Conclusion: Sectioning and extensive examination of the fimbrial end (SEE-FIM) should be routinely done as it provides the opportunity to detect the early malignant changes. It may help in evolving the strategies for early detection, management, and reducing mortality.

Assessment of Knowledge Regarding Antibiotic Use, its Resistance, and Future Consequences among Higher Secondary Students in Private Schools of Kathmandu Valley

Antimicrobial resistance poses a growing threat to public health, as infections from resistant strains of microbial become increasingly difficult and expensive to treat, resulting in prolonged illness and greater risk of death. A cross-sectional descriptive study was done among 471 higher secondary level students of private schools in Kathmandu Valley. Data were collected from Grade 11 and 12 non-science faculty students through self-administered questionnaires. Half (50.5%) of the students gave correct response by saying that antibiotic kills bacteria and 49.1% said that it is for fever. Majority (93.0%) of them said that it should be taken with water. Regarding the response on when to stop taking antibiotic, 46.9% said correctly by saying when all prescribed medicines are taken whereas and 40.8% said that after feeling better. More than half (58.8%) of the students had not heard about antibiotic resistance, whereas those who have heard among them 24% of students said that they had heard from doctor and nurses and 21.8% from family member and friends. Nearly one-third (32.7%) of students knew that antibiotic resistance occurs using antibiotic when they are not necessary. Regarding the response on consequences of antibiotic resistance, more than one-third (38.2%) of students gave correct answer. Nearly half of the students have lack of knowledge about antibiotic. Thus, it is imperative to create awareness among students by introducing a specific course on antibiotic in the 9th and 10th grade core curriculum to prevent antibiotic resistance and its consequences.

Factors associated with increased blood loss during delivery

Background: The present study was done to assess the blood loss during delivery even after active management of third stage of labor with oxytocin and the maternal outcomes of PPH.Methods: We studied 100 pregnant women were either in spontaneous labor or admitted for induction of labor, underwent vaginal delivery or caesarean section in our institute. Active management of third stage of labor in all 100 cases included 10 IU intramuscular oxytocin or 10 to 20 IU intravenous in 500 ml of Ringer’s Lactate. Blood loss in all cases was noted.Results: Of the included cases, 27 had to be given extra-uterotonics for atonic uterus, of which 12 parturient still had PPH. Atonic uterus was the cause of PPH in 11 of the 12 cases, while one case was of atonic uterus plus trauma. Half of all PPH cases responded to medical management alone, five cases had to undergo tamponade/stepwise devascularization and one case had to undergo obstetric hysterectomy. Blood loss was significantly higher in women aged more than 35 years, primigravida, not in labor, oligohydramnios or post-datism, elective LSCS, scarred uterus in and had more than 1 high risk factor. Among various high-risk conditions, significantly higher blood loss was observed in patients with chronic hypertension, gestational hypertension, pre-gestational diabetes mellitus, multipara with prior PPH, placenta previa, preeclampsia and sickle cell trait.Conclusions: Fifteen women avoided PPH by using a reliable method of blood loss measurement and initiating interventions early. Organized PPH management protocol morbidity and mortality of the mother and neonate can be prevented.

A study of prevalence of migraine in stroke patients and its association with ischemic versus hemorrhagic stroke: a cross sectional study

Background: Migraine is characterized by recurrent attacks of disabling headache and autonomic nervous system dysfunction. Up to one third of patients also have neurological aura symptoms. It has been suggested that migraine can be a risk factor for stroke. Migraine affects three times the number of women than men. The incidence of stroke in men is two times that of women. It is shown in several studies that women aged 35 to 45 years old are at increased risk of ischemic stroke who had migraine with or without aura.Methods: The present cross sectional study was conducted in 350 consecutive patients of stroke who were attended OPD and admitted in wards of the Department of Medicine, M.G.M. Medical College and MY Hospital, Indore, MP, India, during period from December 2017 to December 2018.Results: The highest percentage of respondents i.e. 68% belonged to male group followed by 32% of respondents who were females. The highest percentage of respondents i.e. 66.6% had ischemic stroke while, 33.4% had hemorrhagic stroke. The highest percentage of respondents i.e. 90.9% had no Migraine while, 9.1% had Migraine. The highest percentage of respondents i.e. 31.2% had weekly reoccurrence, followed by forth nightly (25%) and lowest was 3.1% of daily recurrence. The association of type of stroke with sex group of patient’s history of headache which found to be significant (p ?0.05). The association of type of stroke with sex group of patient’s history of various cerebro-vascular risk factors which found to be significant (p<0.05). Patients having hemorrhagic and ischemic stroke also had HTN in 47% and 12.4% patients respectively.Conclusions: In this study it is concluded that migraine can be established as a risk factor for ischemic stroke. Early diagnosis and treatment with available medication can be helpful in prevention or decreasing risk for developing stroke.

An Invitro Study Of Determination Of Anti-Bacterial, Antioxidant, Anti- Inflammatory Potential Of Piper Betel Essential Oil.

Abstract: Background: Piper betel Linn is considered to possess important medicinal values. Leaves are considered more valuable part and was used in past for preventing halitosis. Essential oil obtained from leaves have been tried for antibacterial potential against various oral bacteria such as Streptococcous mutans, Actinomyces species and has demonstrated effective role in suppressing plaque formation. In addition essential oil obtained from leaves also exhibits anticancer properties because of antioxidant and anti-inflammatory potential. However available literature falls short in evaluating antibacterial potential of Piper betel essential oil against common periodontal pathogens- Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Prevotella intermedia. Present invitro study was conducted to evaluate antibacterial potential of Piper betel essential oil against previously mentioned periodontal pathogens by determination of minimum inhibitory concentrations (M.I.C).Antioxidant and Anti-inflammatory potential was also determined for the same. Methodology: Antibacterial potential was determined using Disc diffusion test and Broth Microdilution method. Antioxidant and anti-inflammatory potential was determined by measurement of superoxide dismutase (SOD) activity using riboflavin-NBT assay and detection of MMP-2 and MMP-9 by gelatin zymography method respectively. Results: Piper betel essential oil is an effective antibacterial activity against the tested periodontal pathogens along with antioxidant and anti-inflammatory potential. Conclusion: Piper betel essential oil possesses effective antibacterial, antioxidant and anti-inflammatory potential and could be used effectively in formulation of oral health care product.

A study on factors influencing farmer’s satisfaction level towards Agricultural produce marketing committee (Rajnandgaon district).

Agriculture is an important element of Indian economy. The vast majority of this country’s population depends on agriculture for its livelihood. So it becomes very important to offer farmers a fair market for his produce at fair price .Governments agricultural policies and Agri-marketing schemes should be huge,effective, organized and systematic. For fulfilling this purpose the Agricultural produce marketing committees were established. They work under district regulated market set up by the different state governments to sell the agricultural produce directly from farmer(as seller) to purchasers . There is no middleman in between the market transactions. The present study is focused on the factors influencing farmers satisfaction level towards Agricultural produce marketing committee of Rajnandgaon district .
