BACKGROUND AND OBJECTIVES: Percutaneous peripheral nerve stimulation (PNS) is an analgesic modality involving the insertion of a lead through an introducing needle followed by the delivery of electric current. This modality has been reported to treat chronic pain as well as postoperative pain following knee and foot surgery. However, it remains unknown if this analgesic technique may be used in ambulatory patients following upper extremity surgery. The purpose of this proof-of-concept study was to investigate various lead implantation locations and evaluate the feasibility of using percutaneous brachial plexus PNS to treat surgical pain following ambulatory rotator cuff repair in the immediate postoperative period...

The finding of gallbladder polyps on imaging studies prompts further workup. Imaging results are often discordant with final pathology. The goal of this study is to compare polypoid lesions of the gallbladder found on preoperative ultrasound (US) with final pathologic diagnosis after cholecystectomy to help guide clinical decision-making. A retrospective study was conducted identifying adult patients who were diagnosed with polyps via US and who underwent cholecystectomy from 2008 through 2015. Imaging data, final pathology, and demographics were manually reviewed...

Accurate preoperative clinical staging is essential to optimize the treatment of rectal cancer. Primary surgical resection is typically indicated for stage I disease, whereas neoadjuvant therapy is recommended for stages II and III. The objective of this study is to examine the accuracy of clinical staging using current imaging modalities in predicting pathologic stage and, thus, selecting appropriate treatment. Adult patients with nonmetastatic rectal cancer who underwent primary surgical resection were identified from the National Cancer Database between 2006 and 2014...

The treatment of non-small cell lung cancer (NSCLC) includes surgical resection with curative intent in early-stage disease and chemoradiation in the advanced stage disease. Therefore, an accurate preoperative mediastinal lymph node staging is required not only to offer the appropriate treatment but also to avoid unnecessary invasive procedures including thoracotomy. The mediastinal lymph nodes can be sampled using several techniques including mediastinoscopy, surgery (open or video-assisted thoracoscopic surgery), endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration (TBNA), or endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA)...

BACKGROUND: Drug-induced melanoma is a topic, concept or "reality" becoming more and more popular as the list of drugs considered as potential inducers of cutaneous melanoma is constantly growing. Interesting and current at the moment is the question/dilemma of "Irbesartan induced melanomas" and "Valsartan induced melanomas"! The following questions are without answers: 1) the general risk which angiotensin receptor blockers contain for potentiating the carcinogenesis and cancer development (as a whole); 2) available officialized data for withdrawal from the market of products with valsartan and irbesartan due to detected potential carcinogens-NDMA/NDEA, and 3) the missing official information on the most likely forms of cancer potentiated by these drugs...

BACKGROUND: Necrotizing pancreatitis (NP) is a severe systemic inflammatory process. We have observed a high incidence of venous thromboembolism (VTE) in NP patients. However, remarkably few data exist to document the true incidence of VTE-including splanchnic vein thrombosis (SVT), extremity deep venous thrombosis (eDVT), and pulmonary embolism (PE)-in NP. Therefore, we sought to determine the incidence and risk factors for VTE in NP patients. METHODS: Retrospective review of all NP patients treated at a single academic center between 2005 and 2015...

Pancreatic granular cell tumors (GCTs) are rare and making an imaging diagnosis of pancreatic GCT is difficult because it has no definite characteristics on contrast-enhanced computed tomography (CE-CT) or magnetic resonance imaging (MRI) owing to varying findings. We report about a 32-year-old woman who presented with an incidental finding of a pancreatic tumor with a past history of excision of a right forearm GCT nodule 12 years ago. CE-CT revealed a 23-mm-sized homogeneous low enhancement tumor in the arterial phase in the pancreatic body...
