BACKGROUND AND AIM: It has been speculated that impaired salivary flow contributes to abnormal acid clearance in patients with erosive esophagitis (EE). For easy and objective assessment of salivary function, we developed a salivary gland blood flow measurement technique using continuous-wave Doppler sonography. In the present study, we evaluated the salivary secretory function in patients with EE and those with nonerosive reflux disease (NERD) using this method. METHODS: Doppler waveform analysis was performed on the facial artery to assess blood inflow to the submandibular gland of 30 healthy subjects (HS)...

BACKGROUND: Ultrasound Tissue Doppler imaging (US-TDI) has been used to diagnose regional wall motion (WM) abnormalities in coronary artery disease, but has not been applied to oropharyngeal diseases. This study aimed first to validate an US-TDI method to assess cervical esophageal (CE) WM, and secondly to use the method to evaluate CE WM in patients with oropharyngeal dysphagia (OD). METHODS: First, we enrolled 22 healthy men (mean age: 59.7 years) who all underwent both US-TDI and videofluoroscopy (VF) and then esophageal high-resolution manometry (HRM) in the same week...

BACKGROUND AND AIMS: Gastric varices (GV) have higher rates of morbidity and mortality from hemorrhage than esophageal varices. Several studies have shown the safety and efficacy of cyanoacrylate (CA) injection for acute gastric variceal hemorrhage. We report data from our experience with CA injection for GV before and after routine use of post-injection audible Doppler assessment (ADA) for GV obturation and describe long-term outcomes after this therapy. METHODS: We retrospectively identified patients who had documented GV, underwent CA injection, and had at least 2 weeks of follow-up...

BACKGROUND: Thoracic epidural analgesia (TEA) combined with general anesthesia decreases anesthetic requirements by half when hemodynamic criteria are used for the titration of analgesia. We therefore determined the impact of TEA on anesthetic requirements, when a closed-loop controller was used allowing the automated coadministration of propofol-remifentanil guided solely by the Bispectral index. METHODS: This single-center double-blind study enrolled patients scheduled for elective posterolateral thoracotomy using TEA...

Transjugular intrahepatic portosystemic shunt (TIPS) placement is a standard procedure for the treatment of portal hypertension complications. When this conventional approach is not feasible, alternative procedures for systemic diversion of portal blood have been proposed. A one-step interventional approach, combining minilaparotomy-assisted transmesenteric (MAT) antegrade portal recanalization and TIPS, is described in an adolescent with recurrent esophageal varice bleeding and portal cavernoma (PC). A 16-year-old girl was admitted to our Unit because of repeated bleeding episodes over a short period of time due to esophageal varices in the context of a PC...

BACKGROUND/AIMS: The standard of care for older patients with oropharyngeal dysphagia (OD) is poor. Stimulation of transient receptor potential vanilloid 1 might become a pharmacological strategy for these patients. This study aimed to compare the therapeutic effect of film food containing 0.75 µg of capsaicin in these patients. METHODS: In a crossover, randomized trial, 49 patients with OD were provided capsaicin or identical placebo at least 7 days apart. Patients' reported symptoms during repeated swallowing, the volume, pH and substance P (SP) concentrations in saliva, and cervical esophageal wall motion evaluated by ultrasonographic tissue Doppler imaging were obtained before and after capsaicin or placebo administration...

During heat stress, blunted increases in skin sympathetic nervous system activity (SSNA) and reductions in end-organ vascular responsiveness contribute to the age-related reduction in reflex cutaneous vasodilation. In older adults, folic acid supplementation improves the cutaneous vascular conductance (CVC) response to passive heating; however, the influence of folic acid supplementation on SSNA:CVC transduction is unknown. Fourteen older adults (66 ± 1 yr, 8 male/6 female) ingested folic acid (5 mg/day) or placebo for 6 wk in a randomized, double-blind, crossover design...

Continuous cardiac afterload evaluation could represent a useful tool during general anesthesia (GA) to titrate vasopressor effect. Using beat to beat descending aortic pressure(P)/flow velocity(U) loop obtained from esophageal Doppler and femoral pressure signals might allow to track afterload changes. Methods We defined three angles characterizing the PU loop (alpha, beta and Global After-Load Angle (GALA)). Augmentation index (AIx) and total arterial compliance (Ctot) were measured via radial tonometry. Peripheral Vascular Resistances (PVR) were also calculated...

BACKGROUND: The anterolateral thigh flap is a workforce flap in reconstructive surgery, however, variations in it is vascular anatomy are not uncommon. These variations may affect flap design and survival, especially when large flaps are required. In some anatomical variants the anterolateral thigh flap is supplied by two separate dominant pedicles, and in these cases a bi-pedicle modification may be necessary to ensure complete flap viability. The aim of this report is to evaluate the outcomes, and present our approach in using bi-pedicle anterolateral thigh flaps as a method to reduce the risk of partial flap necrosis when reconstructing sizeable soft tissue defects...

Reflex cutaneous vasodilation in response to passive heating is attenuated in human aging. This diminished response is mediated, in part, by age-associated reductions in endothelial function; however, the contribution of altered skin sympathetic nervous system activity (SSNA) is unknown. We hypothesized that 1) healthy older adults would demonstrate blunted SSNA responses to increased core temperature compared with young adults and 2) the decreased SSNA response would be associated with attenuated cutaneous vasodilation...
