RESUMEN
Background: Maternal periodontal disease is a chronic oral infection with local and systemic inflammatory responses and may be associated with adverse pregnancy outcomes. Elevated levels of Creactive protein has been linked to adverse pregnancy outcomes in maternal periodontal disease. Objectives: To assess plasma C-reactive protein levels in pregnant women with chronic periodontitis and in periodontal health and to compare the incidence of preterm delivery in pregnant women having chronic periodontitis and in periodontal health. Materials and Methods: A total of 122 pregnant women aged 18 years and above with gestational age < 26 weeks were recruited and divided into two equal groups (control group, study group) of 61 each. Blood samples were taken from both the groups to determine the serum C-reactive protein. Results: The mean value of C-reactive protein levels in subjects having chronic periodontitis was higher compared to control group i.e., 2.462±0.318 compared to 1.307±0.361 (P<0.001). The incidence of preterm delivery (< 37 weeks) was 82% in the chronic periodontitis group (study group) compared to 3.3% in the control group (P< 0.001). The incidence of low birth weight(<2500g) was 45.9% in chronic periodontitis (study group) compared to 14.8% in the control group (p< 0.001). Conclusion: The findings from the study suggest that periodontal disease in pregnant women is associated with increased C-reactive protein levels in pregnancy. Incidence of preterm delivery and low birth weight infants is higher in pregnant women with chronic periodontitis compared to healthy controls.
RESUMEN
Mammary analogue secretory carcinoma (MASC) of the salivary gland is a malignant tumor which bears morphologic, immunohistochemical and molecular features similar to those of mammary secretory carcinoma. The tumor is considered as a low-grade malignancy perhaps slightly more aggressive than acinic cell carcinoma. High-grade transformation with recurrences, regional nodal involvement, metastases, and cancer-related death has been reported in a few cases. We report an unusual case of large MASC of the parotid gland in a young patient without regional lymph node involvement. To the best of our knowledge till date such a large MASC of the salivary gland has not been reported in the English literature.
RESUMEN
Contractile mechanisms of different parts of the gut in adult and neonate may not be identical due to developmental processes. The present study was undertaken to investigate acetylcholine (ACh) and histamine induced contractile responses of colon and rectum in adult and neonatal albino rats. Contractile responses were recorded from isolated in vitro preparations. The dose-response curve for ACh (0.001-100 μM) revealed dose dependent increase in contractile responses. A significantly (P<0.05) greater contractile responses (g/g wet tissue) was observed in rectum as compared to colon. Atropine pretreatment significantly blocked ACh responses in both rectum and colon. The blockade was higher in adult preparations. The dose-response study for histamine (0.001-100 μM) did not show any significant difference between rectum and colon. Histamine (100 μM) induced contractions were significantly (P<0.05) increased after pretreatment with pheniramine (100 μM) in adult rectum. This potentiating response of pheniramine was absent in neonate rectum. Such effect was also not seen in colon of both adult and neonate. The present investigation indicates that the contractile responses induced by ACh are similar in both adult and neonate, excepting that the blocking effect of atropine in colon was more pronounced in adult as compared to neonate. Further, the results also indicated different mechanism of histamine action in adults and neonates as evidenced by the significant enhancement of contractions by pheniramine only in adult rectum. Therefore, the present results indicate the existence of a different cholinergic and histaminergic activity in adult and neonate as well as in rectal and colonic tissue.
