RESUMEN
Facial appearance is fundamental for communication and interaction with the environment. Attractiveness nowadays reported increasing interest and attention among different ethnicities and varying education level groups. Aim: To study the perception of facial profile attractiveness among Iraqi Orthodontists and Maxillofacial surgeons [as concerned dental professionals] compared to Iraqi lay-individuals. Digital facial profile images were taken for a young male and female, altered in 2 degrees of prognathism and retrognathism in 4, 8 mm for each jaw, and combinations, collecting 12 images each, which were [E-mailed] to a sample of 80 Iraqis [from the pool of Baghdad society]: 40 dental professionals [20 orthodontists, 20 maxillofacial surgeons], and 40 lay individuals, with equally distributed genders. Ratting was carried out for 24 images, scoring each on a numerical scale of 1-10 as the least to the most attractive profile. Significant difference in perception facial profile was found between genders [P<0.05] and among the groups with different dental education [P<0.001]. General agreement was established in all the sample groups on average facial profile to be the most attractive and on the most retrognathicmandibular profile to be the least attractive
RESUMEN
The association of changes in serum trace elements [zinc and lithium] with thyroid hormones [thyroxine and triiodothyronine] in patients with established renal failure studied. Thirty patients of both sexes with established renal failure of divert causes and subjected to renal dialysis were enrolled in this study. Renal dialysis increases the level of thyroid hormones but did not alter the status of serum zinc and lithium. Serum thyoid hormones were correlated positively with serum zinc and negatively with serum lithium. This pattern of correlation was not altered by renal dialysis. It could be concluded that certain trace elements are playing a role in the regulation of thyroid function particularly in diseases other than thyroid
