INTRODUCTION: Transobturator slings can be successfully used to treat stress urinary incontinence and improve quality of life through a minimally invasive vaginal approach. Persistent postoperative pain can occur and pose diagnostic and therapeutic dilemmas. Following a sling procedure, a patient complained of pinching clitoral and perineal pain. Her symptoms of localized clitoral pinching and pain became generalized over the ensuing years, eventually encompassing the entire left vulvovaginal region...

INTRODUCTION: Femoral nerve block (FNB) is considered as a major advance in anterior cruciate ligament (ACL) reconstruction as it reduces the need for parenteral opioids. However, the incidence of transient or even permanent neurological deficits due to the FNB is estimated at 1.94% after knee surgery. The primary objective of this study was to compare local infiltration analgesia (LIA) to FNB during ACL reconstruction procedures. The study hypothesis was that LIA was not less effective than FNB on early postoperative pain...

INTRODUCTION: Cochlear implantation is an increasingly common procedure in the treatment of severe to profound sensorineural hearing loss (SNHL) in children and adults. It is often performed as a day-case procedure. The major drive towards day-case surgery has been from a logistical, economical and societal perspective, but we also speculate that the patient's quality of life (QoL) is at least equal to inpatient surgery if not increased as a result of rapid discharge and rehabilitation...

INTRODUCTION: Craniosynostoses affecting the forehead sutures can not only cause brain damage, but can also have an esthetic impact, because of the associated orbito-naso-frontal deformations. Reshaping the orbito-naso-frontal bandeau (ONFB) is difficult to appreciate perioperatively and should ideally be customized to each child. The aim of this study was to develop a template to guide the surgeon preoperatively towards an ideal customized remodelling of the ONFB. MATERIALS AND METHODS: A previous study conducted on computed tomography scans obtained from healthy children allowed us to conclude that the whole ONFB shape could be accurately described just by the distance measured between the fronto-zygomatic sutures (FZD), independently of age and gender...

Substantial improvement in the understanding of the oncogenic pathways in thyroid cancer has led to identification of specific molecular alterations, including mutations of BRAF and RET in papillary thyroid cancer, mutation of RAS and rearrangement of PPARG in follicular thyroid cancer, mutation of RET in medullary thyroid cancer, and mutations of TP53 and in the phosphatidylinositol 3'-kinase (PI3K)/AKT1 pathway in anaplastic thyroid cancer. Ultrasonography (US) and US-guided biopsy remain cornerstones in the initial workup of thyroid cancer...

INTRODUCTION: Abdominal wall hernias remain as one of the most common problems that the general surgeon has to treat. Although usually straightforward and easy to diagnose by the experienced hands, obstacles appear when contents of the hernia sac include organs. The presence of the appendix inside a femoral hernia (De Garengeot's hernia) is a rare entity which represents multiple challenges, both diagnostic and therapeutic. CASE PRESENTATION: We present a case of a 36-year-old female patient who originally presented to the ED with abdominal/groin pain and a new onset of right inguinal swelling...

CT-guided percutaneous ablation for liver cancer treatment is a relevant technique for patients not eligible for surgery and with tumors that are inconspicuous on US imaging. The lack of real-time imaging and the use of a limited amount of CT contrast agent make targeting the tumor with the needle challenging. In this study, we evaluate a registration framework that allows the integration of diagnostic pre-operative contrast enhanced CT images and intra-operative non-contrast enhanced CT images to improve image guidance in the intervention...

PURPOSE: A radio-guided surgery technique with β(-)-emitting radio-tracers was suggested to overcome the effect of the large penetration of γ radiation. The feasibility studies in the case of brain tumors and abdominal neuro-endocrine tumors were based on simulations starting from PET images with several underlying assumptions. This paper reports, as proof-of-principle of this technique, an ex vivo test on a meningioma patient. This test allowed to validate the whole chain, from the evaluation of the SUV of the tumor, to the assumptions on the bio-distribution and the signal detection...

PURPOSE: Navigation systems commonly used in neurosurgery suffer from two main drawbacks: (1) their accuracy degrades over the course of the operation and (2) they require the surgeon to mentally map images from the monitor to the patient. In this paper, we introduce the Intraoperative Brain Imaging System (IBIS), an open-source image-guided neurosurgery research platform that implements a novel workflow where navigation accuracy is improved using tracked intraoperative ultrasound (iUS) and the visualization of navigation information is facilitated through the use of augmented reality (AR)...
