BACKGROUND: Obesity is a disease that is highly prevalent in Brazil, and the associated comorbidities represent a major global public health challenge. Botulinum toxin type A (BTX-A) is a potent neurotoxin and inhibitor of gastric smooth muscle activity. In theory, BTX-A administration should promote early satiety and weight loss because it delays gastric emptying by inhibiting acetylcholine-mediated peristalsis, which is primarily responsible for gastric motility. Because results in the literature are discrepant, the efficacy of intragastric injections of BTX-A as a primary treatment for obesity remains unknown...

BACKGROUND: Performance of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for staging the radiologically normal mediastinum has been reported with inconsistent findings. We assessed the sensitivity of systematic staging using EBUS-TBNA for detection of radiologically occult mediastinal metastases in cN0/N1 lung cancer. METHODS: Studies evaluating EBUS-TBNA for systematic mediastinal staging in cN0/N1 lung cancer were identified by systematic review...

Recent advances in ultrasound Doppler imaging have facilitated the technique of functional ultrasound (fUS) which enables visualization of brain-activity due to neurovascular coupling. As of yet, this technique has been applied to rodents as well as to human subjects during awake craniotomy surgery and human newborns. Here we demonstrate the first successful fUS studies on awake pigeons subjected to auditory and visual stimulation. To allow successful fUS on pigeons we improved the temporal resolution of fUS up to 20,000 frames per second with real-time visualization and continuous recording...

PURPOSE: Advances in intraoperative imaging and neuronavigation techniques have positively affected glioma surgery. The desire to reduce brain-shift-related problems while achieving the real-time identification of lesions and residual and anatomical relationships has strongly supported the introduction of intraoperative ultrasound (ioUS) in neuro-oncological surgery. This paper presents tips based on our experience with ioUS in neurosurgery. METHODS: We retrospectively analyzed 264 patients who underwent high-grade glioma (HGG) resection at the University of Turin and 60 patients who were treated at the University of Rome...

Ultrasound-guided transversus abdominis plane (TAP) block for abdominal surgery has been widely studied in clinical settings. However, dexmedetomidine as an adjunctive analgesic combined with TAP block has been rarely reported. The present study evaluated the efficacy of TAP block combined with dexmedetomidine adjunct for gynecological laparoscopy. In brief, 90 patients were randomly divided into three groups: Group I, which received post-operative intravenous analgesia only after general anesthesia; Group II, which received a TAP block with 20 ml 0...

BACKGROUND: Hyperthermia is currently used as an alternative to surgery or in combination with chemotherapy and/or radiation therapy in the treatment of oral squamous cell carcinoma. However, little has been known about the change of chemo-sensitivity after hyperthermia and the mechanism underlie it in oral squamous cell carcinoma. METHODS: The aim of this study was to explore the influence of chemo-sensitivity of CAL-27 and SCC-4 cells by histoculture drug response assay after the animal model treated by the ultrasound hyperthermia...

BACKGROUND: Paratesticular fibrous pseudotumor (PFP) is a rare benign tumor that can mimic malignant tumors; thus, radical orchiectomy was the standard treatment in the past. OBSERVATION: A 15-year-old boy came to our attention for a hard right inguinal swelling. An ultrasound showed a highly vascularized mass. The boy underwent a gonadal-sparing excision of the mass that was diagnosed to be a PFP. The patient recovered well, without recurrences at the follow-up...

BACKGROUND: Local excision may be curative for benign and malignant rectal neoplasms. Because many early rectal cancers are discovered incidentally after local excision of clinically benign lesions, it is unclear whether preoperative imaging with transrectal ultrasound or MRI affects management. OBJECTIVE: The purpose of this study was to determine the diagnostic characteristics and effect of preoperative imaging on the incidence of malignancy in benign rectal lesions undergoing local excision...

BACKGROUND: Localization of nonpalpable breast lesions for breast-conserving surgery (BCS) remains highly variable and includes needle/wire localization (NL), radioactive seed localization, radar localization, and hematoma-directed ultrasound-guided (HUG) lumpectomy. The superiority of HUG lumpectomy over NL has been demonstrated repeatedly in terms of safety, accuracy, low positive margin rates, cosmesis, and patient satisfaction. In this study, we evaluate the cost effectiveness of HUG lumpectomy over NL for nonpalpable breast lesions...

BACKGROUND: Cutaneous nerve blockade may improve analgesia after hip surgery. Anaesthesia after the lateral femoral cutaneous (LFC) nerve block is too distal for complete coverage of most hip surgery incisions, which requires additional anaesthesia of the adjacent, proximal area. The transversalis fascia plane (TFP) block potentially anaesthetises the iliohypogastric and subcostal nerves. The primary aim of the present study was to investigate, if the TFP block provides cutaneous anaesthesia adjacent to the LFC nerve block...

BACKGROUND: Approximately 0.6% to 4% of cholecystectomies are performed because of gallbladder polyps. The decision to perform cholecystectomy is based on presence of gallbladder polyp(s) on transabdominal ultrasound (TAUS) or endoscopic ultrasound (EUS), or both. These polyps are currently considered for surgery if they grow more than 1 cm. However, non-neoplastic polyps (pseudo polyps) do not need surgery, even when they are larger than 1 cm. True polyps are neoplastic, either benign (adenomas) or (pre)malignant (dysplastic polyps/carcinomas)...

Background: Patients with uncomplicated biliary disease frequently present to the emergency department for assessment. To improve bedside clinical decision making, biliary point-of-care ultrasound (POCUS) in the emergency department has emerged as a diagnostic tool. The purpose of this study is to analyze the usefulness of POCUS in predicting the need for surgical intervention in biliary disease. Methods: A retrospective study of patients visiting the emergency department who received a biliary POCUS from December 1, 2016 to July 15, 2017 was performed...

Current popular cancer treatment options, include tumor surgery, chemotherapy, and hormonal treatment. These treatments are often associated with some inherent limitations. For instances, tumor surgery is not effective in mitigating metastases; the anticancer drugs used for chemotherapy can quickly spread throughout the body and is ineffective in killing metastatic cancer cells. Therefore, several drug delivery systems (DDS) have been developed to target tumor cells, and release active biomolecule at specific site to eliminate the side effects of anticancer drugs...

BACKGROUND: Pancreatic cystic neoplasms (PCNs) are a spectrum of neoplasms that can be benign or malignant. The accuracy of diagnosis is critical for this disease since different types of PCNs are treated differently using various modalities. The use of a multidisciplinary team (MDT) has been shown to improve the management and outcomes of various diseases. We aimed to determine the performance of MDT in the management of PCNs. METHODS: We retrospectively reviewed 167 pathologically-proven PCN patients and divided them among three groups according to their surgical data and treatment modalities: 1) historical control group (HC group); 2) concurrent control group (CC group); and 3) MDT group...

BACKGROUND: Clinical and electrophysiological assessments prevail in evaluation of traumatic nerve lesions and their regeneration following nerve surgery in humans. Recently, high-resolution neurosonography (HRNS) and magnetic resonance neurography have gained significant importance in peripheral nerve imaging. The use of the grey-scale-based "fascicular ratio" (FR) was established using both modalities allowing for quantitative assessment. OBJECTIVE: To find out whether FR using HRNS can assess nerve trauma and structural reorganization in correlation to postoperative clinical development...
