ABSTRACT
Background: This study was conducted to determine the feto maternal outcome in pregnant women with thyroid disorders. The prevalence of thyroid disorders in present study was 15.75%.Methods: This was a prospective observational study carried out in all pregnant women irrespective of their parity, who attended ANC clinic in department of obstetrics and gynaecology in a tertiary care hospital over a period of 2 years. After registering, the patients were followed up with routine antenatal visits up to delivery and records were reviewed for development of abortion, PIH, preterm delivery, GDM, anemia, placental abruption, still birth, anomalies, fetal distress, meconium stained liquor, low birth weight and neonatal outcome by neonate Apgar score and TSH value.Results: Mean age group in our study was 27.61±3.14. Family history was present in 8% of study group versus 0% in control group which was statistically significant (p=0.028). Eighteen percent of preeclampsia was diagnosed in study group as compared to 4% in control group which was statistically significant (p-value= 0.005). Fourteen percent patients had preterm labour in study group as compared to 6.7% in control group which was statistically significant (p value= 0.047). Increased neonatal TSH was found in study group (61.3%) as compared to control group (32%), this difference was statistically significant (p-value <0.001). There was increased importance of measuring TSH in first trimester as it was statistically significant in study group (p-value <0.001).Conclusions: All pregnant women should be screened for hypothyroidism as early as possible or before conception to prevent any fetomaternal complications.
ABSTRACT
The level of bone crest surrounding the implant is of utmost significance to determine osseointegrated implant success, as preservation of marginal bone height is highly important for long-term dental implant survival. Various approaches have been described in the literature to prevent the crestal bone loss, including platform switching, non-submerged approach, scalloped implants, implant design modifications, progressive loading, immediate implant placement, etc. The purpose of this paper is to review all the possible methods to preserve the crestal bone, when each method should be used and their success rates in an attempt to address this complex problem of crestal bone resorption. "PubMed" and "Google Scholar" were used to find out any studies involving platform switching concept from 1990 up to 2009. Twenty-four studies involving methods for preservation of crestal bone were evaluated, which included 26% studies on platform switching, 22% on non-submerged approach, 17% on scalloped implants, 13% on progressive loading and 22% on immediate implant placement. Crestal bone preservation should be thought of starting from the design of the implant to be placed. The technique to be followed in a given case will depend upon the density of bone, force factors by the patient, bone volume and amount of soft tissues, etc. The best possible method or the combination of the methods should be used to preserve the crestal bone for the long-term success of the implants.
