Factors That Affect the False-Negative Outcomes of Fine-Needle Aspiration Biopsy in Thyroid Nodules

Background. The purpose of this study was to assess the factors that affect the false-negative outcomes of fine-needle aspiration biopsies (FNABs) in thyroid nodules. Methods. Thyroid nodules that underwent FNAB and surgery between August 2005 and January 2012 were analyzed. FNABs were taken from the suspicious nodules regardless of nodule size. Results. Nodules were analyzed in 2 different groups: Group 1 was the false-negatives (n=81) and Group 2 was the remaining true-positives, true-negatives, and false-positives (n=649). A cytopathologist attended in 559 (77%) of FNAB procedures. There was a positive correlation between the nodule size and false-negative rates, and the absence of an interpreting cytopathologist for the examination of the FNAB procedure was the most significant parameter with a 76-fold increased risk of false-negative results. Conclusion. The contribution of cytopathologists extends the time of the procedure, and this could be a difficult practice in centres with high patient turnovers. We currently request the contribution of a cytopathologist for selected patients whom should be followed up without surgery

The role of multislice computerized tomography angiography in assessing postoperative vascular complications in liver transplant patients

Background/aim: Vascular complications can be detected in liver transplant patients. Digital subtraction angiography has served as the gold standard to make this diagnosis; however, due to its invasive nature, ultrasonography is used for the preliminary evaluation. The purpose of this study was to evaluate the role of multislice computerized tomography angiography (MSCTA) in the detection of vascular complications of symptomatic and asymptomatic liver transplant patients and to compare the results with Doppler ultrasound (Doppler US) findings

An unusual cause of diffuse ascites in an infant: colonic duplication associated with bladder duplication

Colonic duplication is usually asymptomatic; however, when it is symptomatic, patients with this anomaly may present with bleeding, constipation, or manifestations of obstruction, perforation, or malignancy. We report the case of a sixteen-month-old boy who presented with diffuse ascites, and had complete colonic duplication and bladder duplication. Duplication of the colon associated with bladder duplication is a rare entity with only a few cases reported in the medical literature. In addition, it is an extremely rare cause of ascites

The reliability of site determination methods in ventrogluteal area injection: A cross-sectional study

Background: While administering medication through intramuscular injection, the ventrogluteal site must be used instead of the dorsogluteal site, and it is of great significance to locate the ventrogluteal site correctly
