Case report on Irritational Fibroma.

Traumatic or irritation fibroma is the healed end product of the inflammatory hyperplastic lesion, which can occur at any age from almost any softtissue site, tongue, gingiva, and buccal mucosa being the most common. It is usually characterized by a slow, painless growth accumulated over a period of months or years.

Effect of Hand and Ultrasonic Scaling-Root Planing Methods on Tooth Surface Topography: An In-Vitro Atomic Force Microscopy Study.

PURPOSE: Any instrumentation on the tooth surface for plaque or calculus removal will cause some amount of roughness on the tooth surface. Hence, this study was proposed to investigate the effects of hand and ultrasonic scaling and root planing on enamel and cementum, respectively. MATERIALS AND METHODS: Forty tooth samples were prepared from extracted maxillary and mandibular first pre-molars and were divided randomly into four groups of 10 samples each. Group l: received ultrasonic scaling on enamel; Group II: received hand scaling on enamel surface; Group III: root planing with an ultrasonic unit on the cementum samples; and Group IV: root planing using hand curettes on cementum surface. The amount of roughness produced on the surface of each sample of all four groups was evaluated using atomic force microscopy (AFM) and statistically analyzed using Chi-square, ANOVA, and Wilcoxon tests. RESULTS: The results suggested that the surface roughness produced on both crown and root after scaling and root planing (SRP) using a hand instrument is lower than that of an ultrasonic unit. The roughness of the crown was found to be lower than that of the root after SRP using both a hand instrument and an ultrasonic unit and was also statistically significant (P = 0.034). In contrast, there is not enough evidence to conclude a significant difference (P=0.13) between root planing using hand instruments and ultrasonic scaler groups. The combined p-value using the Chi-square test (P=0.026) suggests a statistically significant overall difference between crown and root groups. CONCLUSION: From the present study, the authors concluded that scaling as well as root planing using an ultrasonic unit cause more tooth (enamel and cementum) surface roughness as compared to hand scaling and root planing. While there is no significant difference in the surface roughness of root-cementum produced due to the root planing in both groups, crown-enamel exhibits a significant difference after scaling in both groups. Clinical significance of the study: Rough, uneven tooth surfaces negatively influence the anticipated healing of the periodontium by providing retention areas for microbial dental plaque.

Digital Storytelling and Community Engagement to Find Missing TB Cases in Rural Nuh, India.

Nuh, Haryana, is one of India's least developed districts. To improve TB case notifications, ZMQ carried out an active case-finding (ACF) intervention conducted by community health workers (MIRAs) using a digital TB storytelling platform to create TB awareness in the community. The combined storytelling and ACF intervention were conducted house-to-house or in community group settings. Steps included (A) the development of digital TB awareness-raising stories using a participatory approach called Story Labs; (B) the implementation of the intervention; and (C) process, outcome, and impact evaluation of these activities. Six digital stories were created and used during ACF in which 19,345 people were screened and 255 people were diagnosed with TB. Of 731 participants surveyed, the stories were well received and resulted in an increase in TB knowledge. ACF activities resulted in a 56% increase in bacteriologically confirmed TB and an 8% decrease in all forms of TB compared to baseline. All form notifications may have been impacted by COVID-19 lockdowns. Digital TB storytelling can improve TB awareness and knowledge, particularly for low-literacy populations. The use of these tools may benefit ACF campaigns and improve TB case finding.

Long chain polyunsaturated fatty acids in mothers and term babies.

AIM: To establish the levels of docosahexaenoic acid (DHA) and arachidonic acid (AA) in both plasma and erythrocytes of maternal and cord blood as well as in breast milk of mothers delivering babies at term. METHODS: A total of 148 mothers delivering babies at term were recruited from Bharati Medical Hospital, Pune, India. RESULTS: Levels of DHA and AA in both plasma and erythrocyte were higher in cord blood compared to levels in maternal blood (P<0.001). Maternal plasma and erythrocyte DHA levels had a positive association with the respective levels in cord blood (P<0.001). However, such an association was not seen for AA levels. Maternal plasma omega 3 and omega 6 fatty acids were positively associated with the respective milk fatty acids (P<0.01). CONCLUSIONS: Our results indicate that milk long-chain polyunsaturated fatty acids (LCPUFA) status reflects the concentrations of maternal LCPUFA in women delivering babies at term. Improving the maternal LCPUFA status throughout pregnancy and lactation may improve the milk LCPUFA status and ultimately benefit the infant.

High maternal plasma antioxidant concentrations associated with preterm delivery.

BACKGROUND/AIMS: Our earlier study has shown that increased maternal oxidative stress and reduced antioxidants like vitamin E and C play an important role in fetal growth in preeclampsia. However, the role of antioxidants and their effects on gestation and birth outcome in normotensive pregnancies are not conclusive. The present study examined plasma malondialdehyde as a marker of oxidative stress and antioxidant concentrations (vitamins E and C) in maternal as well as in cord blood samples in normotensive women who delivered both preterm and at term. METHODS: 140 normotensive pregnant women were recruited at Bharati Medical Hospital, Pune, India, during the year 2007. Maternal and cord samples were examined for oxidative stress levels and vitamin C and E concentrations in women who delivered preterm (n=40) and at term (n=100). Mean values were compared with those of women delivering at term using the t test. RESULTS: Increased (p<0.05) oxidative stress was seen in preterm mothers as well as in cord samples. Preterm mothers had higher vitamin C concentrations (p<0.05), and these were positively associated with oxidative stress (p=0.02). Vitamin E levels were comparable between groups. CONCLUSIONS: Increased maternal circulating vitamin C concentrations and increased oxidative stress are associated with preterm delivery.

Effect of thiazide drug compound on the testicular protein and cholesterol contents of albino rat.

In this study the effect of thiazide diuretic compound on the protein and cholesterol contents in the testes of albino rats as the experimental model. The drug thiazide was administered orally daily for 10,20 and 30 days at the dose of 100mg/kg body weight. Total protein decrease in the testes of rats were evidenced may be due to the side effects of thiazide drug compound which is linked with the hyponatremia and protein metabolism. An elevated level of cholesterol contents observed in thiazide treated rats also revealed that the side effect of drug compound thiazide and also may be due to the stimulation of catecholamine which is stimulated therefore, the biochemical estimation such as protein and cholesterol in the testes after the thiazide treatment determined the effectiveness of diuretic drug compound would provide clinical evidences of their side effects.

Reduced placental docosahexaenoic acid levels associated with increased levels of sFlt-1 in preeclampsia.

Our earlier studies, in preeclamptic women have shown altered levels of long chain polyunsaturated fatty acids (LCPUFA), essential constituents of the cell membrane lipids responsible for membrane stability as one of the key factors contributing to the pathophysiology of preeclampsia. We have also reported elevated levels of sFlt-1 in preeclampsia. The present study examines the levels of LCPUFA and their association with sFlt-1 levels in 69 pre-eclamptic women and 40 normotensive women. DHA and omega 3 fatty acid levels were lower (p<0.001) while arachidonic acid and omega 6 fatty acid levels were higher (p<0.05) in preeclamptic women as compared to normotensive women. Maternal plasma sFlt-1 levels were higher (p<0.05) in preeclamptic women and were negatively associated with DHA (p=0.008) and omega 3 fatty acids concentrations (p=0.031). Our results suggest that altered placental LCPUFA may result in altered membrane lipid fatty acid composition leading to increased release of sFlt-1 in circulation.

Global DNA methylation patterns in placenta and its association with maternal hypertension in pre-eclampsia.

Maternal nutrition is an important determinant of one-carbon metabolism that lies at the heart of intrauterine epigenetic programming. Exchange of nutrients and other vital molecules between the mother and fetus takes place across the placenta and hence may play direct role in fetal programming. Pre-eclampsia (PE) originates in the placenta and altered maternal nutrition may influence epigenetic patterns in the placenta, thereby affecting birth outcome. In the present study, we investigated the global DNA methylation levels in placentas of pre-eclampsia women (i.e., women delivering at term and those delivering preterm) and studied their associations with maternal blood pressure and birth outcome. Increased homocysteine and global DNA methylation levels were seen in the pre-eclampsia group (term and preterm PE) when compared with the normotensive group (p < 0.05). A positive association between global DNA methylation and systolic (p < 0.01) and diastolic (p < 0.05) blood pressure was seen in the term pre-eclampsia group, whereas there was no association with birth outcome. The study for the first time provides evidence for altered global DNA methylation patterns in pre-eclampsia placentas and its association with blood pressure. It is possible that increased homocysteine levels may be related to increased methylation in pre-eclampsia.

Circulating angiogenic factors and their association with birth outcomes in preeclampsia.

This study was designed to test the hypothesis that altered angiogenic factors together with increased oxidative stress and reduced docosahexaenoic acid (DHA) levels may be associated with altered birth outcome parameters. To test this hypothesis, levels of plasma vascular endothelial growth factor (VEGF), placental growth factor (PlGF), soluble fms-like tyrosine kinase-1 (sFlt-1), the oxidative stress marker malondialdehyde (MDA) and fatty acids were estimated in women with preeclampsia and their cord samples and compared with those in normotensive women. The association of these parameters with birth outcome was also examined. Our results show that in preeclamptic women, maternal plasma VEGF and PlGF levels were lower, whereas sFlt-1 levels were higher (P<0.05 for all) than in normotensive women. In contrast, cord plasma VEGF levels were higher (P<0.05) in preeclamptic women, whereas there was no difference in sFlt-1 levels. Plasma DHA levels in both the mother and cord were lower (P<0.05) in the preeclamptic group compared with normotensive women. Maternal plasma sFlt-1 levels were positively (n=23, r=0.415, P=0.039) associated with MDA concentrations in preeclamptic women. Maternal plasma sFlt-1 levels showed a strong negative association with baby weight (n=37, r=-0.547, P=0.001), head circumference (n=37, r=-0.472, P=0.005) and baby chest circumference (n=37, r=-0.375, P=0.032) in the preeclamptic group. Cord plasma sFlt-1 concentrations were negatively associated with cord plasma DHA concentrations (n=28, r=-0.552, P=0.004). This study suggests that dysregulation of angiogenic factors may be associated with maternal oxidative stress. Increased oxidative stress may reduce cord DHA levels and increase sFlt-1 levels, leading to poor birth outcomes in preeclampsia.

Long-chain polyunsaturated fatty acid composition of breast milk in pre-eclamptic mothers.

BACKGROUND: Maternal fatty acid nutrition during pregnancy and lactation determines the transfer of long-chain polyunsaturated fatty acids via the placenta and through human milk. Neural maturation of breast-fed infants is known to be linked to breast-milk long-chain polyunsaturated fatty acid concentrations. In spite of this, the fatty acid composition of breast milk in pre-eclamptic mothers is poorly understood. OBJECTIVES: To compare the fatty acid composition of breast milk of pre-eclamptic (n = 45) with normotensive (n = 85) mothers and examine the association of breast-milk fatty acids with plasma fatty acids. METHODS: Milk and plasma fatty acid methyl esters were prepared and analyzed by the modified method of Manku and colleagues using gas chromatography. RESULTS: Docosahexaenoic acid (DHA) concentrations were significantly increased (p < 0.01) in breast milk in spite of lower maternal plasma DHA concentrations (p < 0.05) in pre-eclamptic women. However, there was no difference in arachidonic acid levels between groups in spite of reduced maternal plasma arachidonic acid levels. CONCLUSIONS: The data suggest that in pre-eclampsia, the relation between plasma and milk DHA is altered. The resulting higher milk DHA concentrations are beneficial for infants.
