ABSTRACT
To evaluate the relation between serum thyroid-stimulating hormone [TSH] and development of differentiated thyroid cancers in nodular thyroid disease [NTD] in Egyptians. One hundred patients were included in this study at Al-Azhar University Hospitals from 2010 to 2013; all patients with NTD, who were fi t for surgery, were selected for study. The preoperative TSH level was estimated and was compared with the final histopathological diagnosis for the presence of malignant thyroid lesions. A total of 100 patients were included in the study, with an average age of 46 years. The male to female ratio was 1: 4.7. Seventy-five patients had multinodular goiter, whereas 25 patients had a solitary thyroid nodule. Eighty-six patients underwent total thyroidectomy, whereas 14 patients underwent near- total thyroidectomy. The final histopathological data showed no evidence of malignancy in 83 patients, 83% [benign group], whereas malignant lesions were present in 17 patients, 17% [malignant group]. The preoperative mean TSH level in the benign group was 1.72 +/- 1.4 mIU/L, whereas the mean TSH concentration in the malignant group was 2.61 +/- 2.2 mIU/l. There is a definite relation between serum TSH and development of differentiated thyroid cancers in NTD as the risk of thyroid malignancy increases with increased serum TSH concentrations
ABSTRACT
To evaluate the rate of visualization of normal appendix, its caliber and position among patients without history of prior surgery presenting to the Radiology Department for non-contrast renal CT scan in stone protocol. A total of 125 patients with no history of appendectomy who underwent non-contrast computed tomography scan in stone protocol for evaluation of their renal colic between March and August 2011 were included in this study and their images were reviewed. Identification of normal appendix, its contents and location along with the adequacy of intraperitoneal fat were evaluated in both axial, coronal and sagittal planes. Normal appendices were visualized in 91.2% of cases. The most common location of appendiceal tip was paracolic, and the maximum outer diameter of the normal appendix ranged between 3 and 9mm [mean 5 +/- 1.2 mm]. Intraperitoneal fat was adequate in 71% of the cases. Most of normal appendices are seen on non-enhanced Multi Detector Computed Tomography scan in stone protocol as identification of normal appendix is critical to exclude the diagnosis of acute appendicitis among patients with right sided abdominal pain
