Randomized Controlled Trial Comparative Study
Randomized clinical trial of endovenous laser ablation compared with conventional surgery for great saphenous varicose veins.
Endovenous laser ablation (EVLA) is a popular minimally invasive treatment for varicose veins. Surgical treatment, featuring junctional ligation and inversion stripping, has shown excellent clinical and cost effectiveness. The clinical effectiveness of both treatments was compared within a randomized trial. ⋯ NCT00759434 (http://www.clinicaltrials.gov).

Despite widespread use of imaging technologies including ultrasonography and computed tomography, rates of negative appendicectomy and perforated appendicitis remain high. This trend analysis examined whether rates of negative appendicectomy and perforated appendicitis have decreased over time, and sought to evaluate clinical predictors associated with negative appendicectomy and perforated appendicitis. ⋯ The rate of negative appendicectomy decreased over time, without an accompanying increase in perforated appendicitis. The risk of having a negative appendicectomy was highest in girls aged 12-18 years without local or generalized peritonitis during the early study period, whereas perforation was associated with age over 36 years, presence of localized or generalized peritonitis, and greater co-morbidity.

A previous study demonstrated that Fourier transform infrared (FTIR) spectroscopy can distinguish thyroid cancer from benign thyroid lesions. The aim of this study was to explore the use of FTIR for identifying metastatic lymph nodes of papillary thyroid cancer in vitro, and distinguishing between metastatic and non-metastatic tissue. ⋯ FTIR spectroscopy is a novel technique for detection of metastatic lymph nodes and may prove useful in surgery for papillary thyroid cancer.
