INTRODUCTION: Hepatoblastoma with tumour thrombi extending into inferior-vena-cava and right atrium are often unresectable with an extremely poor prognosis. The surgical approach is technically challenging and might require major liver resection with vascular reconstruction and extracorporeal circulation. However, which is the best surgical technique is yet unclear. PRESENTATION OF CASE: A 11-months-old boy was referred for a right hepatic lobe mass(90×78mm) suspicious of hepatoblastoma with tumoral thrombi extending into the inferior-vena-cava and the right atrium, bilateral lung lesions and serum alpha-fetoprotein level of 50...

OBJECTIVES: Significant muscle wasting develops in critically ill adults, with subsequent worse outcomes. In the pediatric setting, occurrence and effects of muscle wasting are undescribed; this is in part due to a lack of validated, objective methods for assessing muscle wasting. A single measurement of quadriceps femoris thickness has failed to show consistent reproducibility. We hypothesized that averaging repeated measurements could afford good reproducibility to allow for quadriceps femoris thickness decline detection and monitoring...

Typical sources for graft material utilized in minimally invasive transforaminal lumbar interbody fusion include both autograft and allograft. Autograft is frequently utilized due to its theorized benefits in promoting fusion. During minimally invasive transforaminal lumbar interbody fusion, autograft is often obtained locally during the laminectomy and facetectomy. However, this locally obtained bone graft has exhibited questionable osteoconductive properties, often necessitating the addition of biologics to improve fusion rates...

BACKGROUND: Mammaplasty surgery has been modified in the past few years, as plastic surgeons worked to improve and maintain the breast shape and especially the "bottoming out" of the gland. The classic Pitanguy's technique has been shown to be an anatomically safe technique in the management of the breast. However, as first described, cannot be applied in gigantomastia or in severe breast ptosis cases or in cases of dense breast parenchyma or for a long-lasting breast lift result. Using 2 different modifications, the Pitanguy technique can be applied for breasts of all sizes and for all cases of breast ptosis...

OBJECTIVE: National examination of open proctectomy (OP), laparoscopic proctectomy (LP), and robotic proctectomy (RP) in pathological outcomes and overall survival (OS). BACKGROUND: Surgical management for rectal adenocarcinoma is evolving towards utilization of LP and RP. However, the oncological impacts of a minimally invasive approach to rectal cancer have yet to be defined. METHODS: Retrospective review of the National Cancer Database identified patients with nonmetastatic locally advanced rectal adenocarcinoma from 2010 to 2014, who underwent neoadjuvant chemoradiation, surgical resection, and adjuvant therapy...

For more efficient photoelectrochemical water splitting, there is a dilemma that a photoelectrode needs both light absorption and electrocatalytic faradaic reaction. One of the promising strategies is to deposit a pattern of electrocatalysts onto a semiconductor surface; leaving sufficient bare surface for light absorption, while minimizing concentration overpotential as well as resistive loss at the ultramicroelectrodes for faradaic reaction. This scheme can be successfully realized by "maskless" direct photoelectrochemical patterning of electrocatalyst onto an SiOx/amorphous Si (a-Si) surface by light-guided electrodeposition technique...

Surface plasmon resonance (SPR) sensors operate mainly on prism and grating coupling techniques, with spectral and angular scans being the two major interrogation schemes. Among them, the angular scan technique has several advantages including higher measurement precision owing to its higher signal-to-noise ratio. The currently available SPR sensor arrangements provide a maximum angular sensitivity of 500°-600° per RIU. Here, we report the study of grating coupled-hyperbolic metamaterial (GC-HMM) sensors with high angular sensitivity...

AIM: The aim of our study was to describe and assess a new method of mesh fixation using clips in Laparoscopic Ventral Mesh Rectopexy (VMR). This technique avoids knots while suturing in pelvis and saves time. METHOD: A systematic search of the literature (PUBMED, EMBASE) was done to find out alternate ways to fix the mesh over the anterior surface of rectum. This technique has not been used before. We performed five operations using this technique. Indication for surgery was full thickness rectal prolapse in all of them...

There is an immediate need to validate the authenticity of digital images due to the availability of powerful image processing tools that can easily manipulate the digital image information without leaving any traces. The digital image forensics most often employs the tampering detectors based on JPEG compression. Therefore, to evaluate the competency of the JPEG forensic detectors, an anti-forensic technique is required. In this paper, two improved JPEG anti-forensic techniques are proposed to remove the blocking artifacts left by the JPEG compression in both spatial and DCT domain...

BACKGROUND: Intraoperative femur fracture (IFF) is a well-known complication in primary uncemented total hip arthroplasty (THA). Variations in implant instrumentation design and operative technique may influence the risk of IFF. This study investigates IFF between a standard uncemented tapered-wedge femoral stem and its second-generation successor with the following design changes: size-specific medial curvature, proportional incremental stem growth, modest reduction in stem length, and distal lateral relief...

BACKGROUND: Coronary anomalies are frequently present in children with transposition of the great arteries (TGA). Such anomalies significantly increase the complexity of arterial switch operations and may have an effect on postoperative outcomes. In this study, we aimed to assess the frequency of coronary anomalies in children with TGA and describe their effect on postoperative outcomes. METHODS: All patients with TGA who underwent an arterial switch operation between 1991 and 2015 were consecutively enrolled in this study...

BACKGROUND: Less-than-optimal long-term patency of the saphenous vein is one of the main obstacles for the success of coronary artery bypass grafting (CABG). Results from the IMPROVE-CABG trial has shown that harvesting the saphenous vein with a pedicle of perivascular tissue less than 5 mm while using manual distention provides comparable occlusion rates but significantly less intimal hyperplasia at early follow-up. The impact of pedicled veins on duration of operations, leg wound infections, and postoperative bleeding is unknown...

Post-operative pain is a problem for many patients and affects recovery, risk of post-operative complications and quality of life. A thorough preoperative evaluation, careful perioperative planning, identification, and individualized treatment of high-risk patients can reduce post-operative pain. Multimodal treatment combines different analgesic techniques in order to utilize synergistic and additive effects of different treatments and has the potential to optimize effects and reduce side effects. Identification and treatment of patients with chronic post-operative pain should be prioritized...

BACKGROUND: Percutaneous dilatational tracheostomy (PDT) has become a standard technique for critically ill patients who require long-term ventilation. The most common early post-operative complication is bleeding related to anatomical variation in vasculature. The procedure is performed at the patient's bedside unless this is deemed unsafe and then the accepted alternative is open tracheostomy in the operating room. OBJECTIVES: To evaluate the use of pre-procedural ultrasound to aid in the decision of whether PDT in critical care patients should be performed at the patient's bedside or by open surgical tracheostomy...
