Technical and surgical aspects of the sphenopalatine ganglion (SPG) microstimulator insertion procedure

2015

Cluster headache (CH) is a debilitating, severe form of headache. A novel non-systemic therapy has been developed that produces therapeutic electrical stimulation to the sphenopalatine ganglion (SPG). A transoral surgical technique for inserting the Pulsante SPG Microstimulator into the pterygopalatine fossa (PPF) is presented herein. Technical aspects include detailed descriptions of the preoperative planning using computed tomography or cone beam computed tomography scans for presurgical digital microstimulator insertion into the patient specific anatomy and intraoperative verification of microstimulator placement. Surgical aspects include techniques to insert the microstimulator into the…

Reply to Drs. Kiaei and Molinaro Regarding the Publication “Comparison of a Bridge Immunoassay with Two Bioassays for Thyrotropin Receptor Antibody D…

2020

Dear Editor,Drs. Kiaei and Molinaro 1 put forth two criticisms of the manuscript published by us 2. They state that the experimental design of this study is flawed and that the authors falsely claim that negative Thyretain™ TSI Reporter BioAssay results for two Graves’ diseases patients undergoing drug treatments means the absence of stimulating antibodies. To substantiate this claim Drs. Kiaei and Molinaro point out that the manufacturer of the Thyretain TSI Reporter BioAssay clearly states in the package insert that “[t]he effects of various drug therapies on the performance of this Kit have not been established” 1. Second, the package insert explicitly states that “[a] negative result do…

Needle Insertion Difficulty Algorithm (NIDA): A novel pilot study to predict Huber needle insertion difficulty in totally implanted devices.

2021

Safeguarding of venous assets in cancer patients provides for positioning vascular devices. In totally implanted central venous access devices, hereinafter referred as TIVADs, it’s necessary introducing Huber needle, into subcutaneous port, to use it. This procedure is not easy for all implanted devices. The procedural difficulty is to be attributed both to the type of the implanted port and to the skill of the clinician. The degree of patient satisfaction is variable and related with the clinician performing the maneuver. It follows a professional dissatisfaction of the clinician and a hesitation of the patient. Moreover, the incorrect positioning of the Huber needle into the port, could …

The Orogastric Tube Guide® as a novel strategy for gastric tube insertion: a prospective, randomized controlled clinical trial

2020

BACKGROUND Gastric tube insertion, either orally or nasally, is daily practice in anesthesia and intensive care. "Blind" insertion represents the common conventional method and is associated with low first-pass success and frequent complications. This trial aimed to evaluate the novel gastric tube guide as a rigid conduit in regard to insertion success rate, time required and associated complications versus the conventional "blind" insertion method. We hypothesized that the insertion success rate is higher using the Orogastric tube guide. METHODS This trial was approved by ethics committee prior to patient recruitment. In a randomized order, anesthetists performed oral insertion of a gastri…

Vibrio vulnificus: from water to host

2017

Vibrio vulnificus is an aquatic pathogen autochthonous from temperate, tropical and subtropical ecosystems where it lives either as a sessile cell, forming biofilms or as a free-swimming cell. From these locations, the pathogen can occasionally infect humans and fish causing a disease named vibriosis. The most severe form of human and fish vibriosis is associated with the pathogen’s ability to spread from the infection site to the bloodstream and multiply, process known as invasion. Before invasion, the pathogen has to colonize the mucosal host surface, process that involves not only bacterial attachment/adhesion but also resistance to mucosal immunity, commensal microbiota (competitors) an…

Single-mode Bragg gratings in tapered few-modes and multimode fibers

2019

We propose the implementation of fiber Bragg gratings in tapered few-mode and multimode fibers to accomplish single-mode operation by reducing the core diameter, while preserving the core-cladding structure. The gratings present a single reflection band, and the device shows low insertion losses after the taper fabrication and the fiber Bragg gratings inscription. The excitation of high-order odd modes in the core of the fiber has been identified as the main loss mechanism; it can be prevented by means of symmetric illumination of the fibers. We also demonstrate the excitation of high-order cladding modes (cladding-air modes) along the taper transitions; these modes can be removed without a…

Bloodstream Infection Incidence of Different Central Venous Catheters in Neonates: A Descriptive Cohort Study

2017

Central venous catheters (CVCs) in neonates are associated with a risk of central line-associated bloodstream infections (CLABSI). Most reports on the incidence of CLABSI in neonates focus on umbilical venous catheters (UVCs) and peripherally inserted central catheters (PICCs). We evaluated the incidence and risk factors for CLABSI in a cohort of neonates with femoral venous catheters (FVCs), UVCs, and PICCs, with a gestational age ≥34 weeks born between January 1, 2006 and June 30, 2013. We included 2,986 neonates with a total of 656 catheters. The CLABSI incidence rate varied from 12.3 per 1,000 catheter-days in FVCs to 10.6 per 1,000 catheter-days in UVCs and 5.3 per 1,000 catheter-days …

Controversies in ameloblastoma management: Evaluation of decision making, based on a retrospective analysis

2020

Background The ameloblastoma management is still challenging to the high recurrence rates and significant morbidity associated with radical treatment. The purpose of this 10-year retrospective study was to analyze the influence of ameloblastoma type and treatment strategy on the long-term outcomes and recurrence rates. Material and Methods The retrospective analyses of 64 histologically-confirmed ameloblastoma cases was performed. The possible risk factors for recurrence and the development of complications were estimated statistically. Results The treatment strategy applied for this group of patients was the following: thirty-four patients (53.1%) were treated conservatively with enucleati…

Genome degeneration and adaptation in a nascent stage of symbiosis

2014

Symbiotic associations between animals and microbes are ubiquitous in nature, with an estimated 15% of all insect species harboring intracellular bacterial symbionts. Most bacterial symbionts share many genomic features including small genomes, nucleotide composition bias, high coding density, and a paucity of mobile DNA, consistent with long-term host association. In this study, we focus on the early stages of genome degeneration in a recently derived insect-bacterial mutualistic intracellular association. We present the complete genome sequence and annotation of Sitophilus oryzae primary endosymbiont (SOPE). We also present the finished genome sequence and annotation of strain HS, a close…
