Comparative Study
Comparison of block and pulsed radiofrequency of the ganglion impar in coccygodynia
Ganglion impar blockis used for the treatment of chronic coccygodynia. Pulsed radiofrequency (PRF) of the ganglion impar is a promising novel technique. The aim of this study was to determine and compare the efficacy of the blockade and PRF of the ganglion impar. ⋯ PRF neuromodulation provides significantly longer pain relief and reduces the risk of recurrence of pain in chronic coccygodynia as compared with blockade of the impar ganglion.

Surgical treatment of distal intraarticular radius fractures remains controversial. Our aim was to compare the clinical and radiological outcomes between volar plating (VP) and external fixation (EF) for distal intraarticular radius fractures two years postoperatively. ⋯ VP and EF result in similar clinical and radiological outcomes after 2 years. Function is not restored to the functionality of the contralateral and noninjured hand.

Cardiac surgery, especially in the presence of cardiopulmonary bypass (CPB), is associated with an inflammatory reaction that may promote microcirculatory alterations, in addition to the general impact on hemodynamics. Anemia and transfusion make patients more susceptible to the deleterious effects of CPB. In this study, it was aimed to evaluate the effect of dilutional anemia, which is caused by CPB and can be treated with 1–2 units of red blood cell (RBC) transfusion, on global tissue oxygenation parameters in cardiac surgery patients. ⋯ Dilutional anemia as a result of CPB mostly occurs in patients with borderline preoperative hemoglobin concentrations and its correction with RBC transfusion does not normalize the degree of microcirculatory and oxygenation problems, which the patients are already prone to because of the nature of CPB. Preventing dilutional anemia and transfusion, especially in patients with preoperative borderline hemoglobin levels, may therefore reduce the burden of impaired microcirculation-associated organ failure in on-pump cardiac surgery.

Hepatitis B virus (HBV) infection is the leading cause of liver fibrosis (LF). The prognosis and management of patients with chronic hepatitis B virus depend on the amount and progression of liver fibrosis. Angiopoietin-like protein 2 (Angptl2) is not only a chronic inflammatory mediator, but also a tissue-remodeling factor. The aim of this study is to explore the predictive value of Angptl2 in different fibrosis stages in patients chronically infected with HBV. ⋯ In patients with chronic HBV infection, Angptl2 level represents a potential biomarker independently associated with fibrosis stages. The combination of Angptl2 with FIB-4 or Angptl2 with APRI performed better than the existing models for diagnosing significant fibrosis.

To compare the inferior vena cava (IVC) indices, identify their variation rates at positive pressure values and accurate predictive values for the volume status in patients with spontaneous respiration receiving different positive pressure support. ⋯ The dIVC had a more accurate predictive role in predicting the volume status when compared with the CI-IVC and ΔIVC, and may be used reliably with positive pressure supports.
