BACKGROUND: The Quantra Hemostasis Analyzer is a novel diagnostic device that uses an ultrasound-based technology, sonic estimation of elasticity via resonance (SEER) sonorheometry, to characterize the dynamic changes in viscoelastic properties of a blood sample during coagulation. Cardiac surgery utilizing cardiopulmonary bypass (CPB) is associated with a significant impact on the coagulation system and can result in perioperative coagulopathy. The aim of this study was to correlate SEER sonorheometry results to corresponding rotational thromboelastometry (ROTEM) and laboratory parameters obtained before, during, and after CPB...

Objective: Primary hyperparathyroidism (PHP) is a common endocrine disease, and its most effective treatment is surgery. Postoperative hypocalcemia is a morbidity of parathyroid surgeries, and it may extend hospitalization durations. The purpose of this study is to determine the predictive factors related to the development of hypocalcemia and hungry bone syndrome (HBS) in patients who underwent parathyroidectomy for PHP. Materials and methods: Laboratory data comprising parathyroid hormone (PTH), calcium, phosphate, 25-OHD, albumin, magnesium, alkaline phosphatase (ALP), blood urea nitrogen (BUN), and thyroid stimulating hormone (TSH) of the patients were recorded preoperatively, on the 1st and 4th days postoperatively, and in the 6th postoperative month, and their neck ultrasound (US) and bone densitometry data were also recorded...

OBJECTIVES: Understanding of the workflow of perioperative ultrasound (US) examination is an integral component of proficiency. Workflow consists of the practical steps prior to executing an US examination (eg, equipment operation). Whereas other proficiency components (ie, cognitive knowledge and manual dexterity) can be tested, workflow understanding is difficult to define and assess due to its contextual and institution-specific nature. The objective was to define the workflow components of specific perioperative US applications using an iterative process to reach a consensus opinion...

BACKGROUND: Pediatric low-grade gliomas (LGGs) account for approximately half of all pediatric central nervous system tumors. The low-grade gliomas' first line of treatment is gross total resection. However, when gross total resection is not possible, options for adjuvant therapy are limited. MRI-guided laser ablation (magnetic resonance-guided laser interstitial thermal therapy (MRgLITT)) offers a new option for treatment in selected cases. We present a description of the current MRgLITT technology and an exemplary case-series review of our experience in its use in LGGs...

BACKGROUND: Prostate cancer is the most commonly diagnosed cancer in men in Nigeria and most cases present when the disease is already in an advanced stage. Radical prostatectomy for early prostate cancer is therefore not a commonly performed operation by urologists in Nigeria. We have had training and significant experience in radical retropubic prostatectomy. We, therefore, report the outcome of our initial experience. MATERIALS AND METHODS: We review the record of men with early prostate cancer who had radical retropubic prostatectomy in our institution from 2007 to 2015...

BACKGROUND: Recently endoscopic combined intrarenal surgery (ECIRS) has been introduced as an innovative approach for the treatment of complex single, multiple, and staghorn urolithiasis, which reveals to be a viable alternative to standard percutaneous nephrolithotomy. Although considered to be a versatile, safe, and efficient endoscopic procedure, it is not free from complications. We would like to report two rare cases of hydroperitoneum that occurred during ECIRS and their management...

BACKGROUND: Intraabdominal fluid extravasation (IAFE) after hip arthroscopy has historically been diagnosed in catastrophic circumstances with abdominal compartment syndrome requiring diuresis or surgical decompression. A previous retrospective study found the prevalence of symptomatic IAFE requiring diuresis or decompression to be 0.16%, with risk factors including surgical procedure and high pump pressures. IAFE can be diagnosed rapidly by using point-of-care ultrasound (POCUS) via the Focused Assessment With Sonography for Trauma (FAST) examination, which is a well-established means to detect free fluid with high specificity and sensitivity...

BACKGROUND: Emergency situations and conditions with impaired gastric emptying enhance the risk of perioperative pulmonary aspiration due to increased residual gastric contents volume (GCV). Gastric ultrasonographic (US) measurement of the gastric antral cross-sectional area (CSA) has been proposed to estimate preanesthetic GCV. However, only few healthy children and fasted pediatric patients have been investigated so far, predicting GCV with considerable imprecision. This study aimed to compare GCV assessed by US in different patient positions for measuring CSA, using magnetic resonance imaging (MRI) as reference, and to evaluate its potential as diagnostic test...

Thoracic paravertebral blocks (TPVBs) have an extensive evidence base as part of a multimodal analgesic strategy for thoracic and breast surgery and have gained popularity with the advent of ultrasound guidance. However, this role is poorly defined in the context of abdominal surgery. We performed a systematic review of randomized controlled trials, to clarify the impact of TPVB on perioperative analgesic outcomes in adult abdominal surgery. We identified 20 published trials involving a total of 1044 patients that met inclusion criteria; however there was significant heterogeneity in terms of type of surgery, TPVB technique, comparator groups and study quality...
