Laryngeal Aerodynamic Analysis of Glottal Valving in Children With Down Syndrome
Down syndrome is one of the most common congenital genetic disorders. Generally, individuals with Down syndrome presents perceptually strained, husky, monotonous, raucous and a typically low pitched voice quality. There are very few attempts made to investigate objective voice characteristics in these individuals. Further, there is no reported data with a specific focus on laryngeal aerodynamics in these individuals. Hence the present study aimed at performing perceptual (GRBAS scale) and laryngeal...

Functional Diversity of Myeloid-Derived Suppressor Cells: The Multitasking Hydra of Cancer [BRIEF REVIEWS]
Myeloid-derived suppressor cells (MDSCs) are immature suppressive cells found in tumors and immunological niches. In this article, we highlight the ability of MDSCs to promote IL-17–producing T cells (Th17) and regulatory T cells in addition to suppressing cytotoxic T cells in different tumor models. These interactions between MDSCs and T cells support tumor growth because IL-17 is tumorigenic in many cancer types and regulatory T cells suppress antitumor T cells. Besides T cells, MDSCs promote regulatory...

18F-FDG-PET/CT-based treatment planning for definitive (chemo)radiotherapy in patients with head and neck squamous cell carcinoma improves regional control and survival
Head and neck squamous cell carcinoma (HNSCC) has a substantial risk of cervical lymph node metastases [1]. For small nodal metastases, it is not uncommon that they remain undetected (i.e. occult) because they fall below the detection threshold of diagnostic imaging [1,2]. In a clinically negative neck (cN0) the prevalence of occult metastases ranges between 10% and 35%, depending on the primary tumor site and T-stage [2]. To eradicate potential occult nodal disease, elective irradiation (typically...

Συνιστώντας μία από τις μεγαλύτερες του είδους της, η μελέτη που δημοσιεύθηκε στο American Journal of Hypertension πραγματοποίησε μία μη στοχοθετημένη μεταβολομική ανάλυση σε περισσότερους από 1.200 συμμετέχοντες στη μελέτη Bogalusa Heart προκειμένου να αναγνωρίσει μεταβολίτες που συνδέονται με τη αρτηριοσκλήρυνση. Παρόλο που η αρτηριοσκλήρυνση (ή αρτηριακή δυσκαμψία) συνιστά έναν ανεξάρτητο και αρκετά σοβαρό παράγοντα κινδύνου για καρδιαγγειακές παθήσεις, ακόμα και θάνατο, οι μηχανισμοί που συμβάλλουν...

Νεότητα: Αυτά είναι τα φάρμακα που εξοντώνουν τα γερασμένα κύτταρα
Κομβική για την κατανόηση της διαδικασίας της γήρανσης ενδέχεται να είναι μία έρευνα από τη Σχολή Μηχανικών του Πανεπιστημίου Viterbi που δημοσιεύθηκε στο Journal of Biological Chemistry. Τα ευρήματα θα μπορούσαν να ανοίξουν το δρόμο για καλύτερες θεραπείες κατά του καρκίνου και επαναστατικά νέα φάρμακα για διάφορες νόσους. «Για να αξιοποιήσει κάποιος την πηγή της νεότητας πρέπει πρώτα να την ανακαλύψει και να κατανοήσει ποια είναι η ακριβής δράση της. Κάνουμε ακριβώς το αντίθετο. Προσπαθούμε να...

Ο παράγοντας που βλάπτει τους πνεύμονες όσο ένα πακέτο τσιγάρα την ημέρα
H ατμοσφαιρική ρύπανση, συγκεκριμένα οι αυξημένες συγκεντρώσεις όζοντος που οφείλονται στην κλιματική αλλαγή, επιδεινώνει το πνευμονικό εμφύσημα σύμφωνα με μελέτη των Πανεπιστημίων Ουάσινγκτον, Κολούμπια και Μπάφαλο. Η νέα έρευνα που δημοσιεύθηκε στο JAMA παρουσιάζει μία σχέση μεταξύ της μακροχρόνιας έκθεσης τους ρύπους, ειδικά στο όζον, με την αύξηση στα περιστατικά εμφυσήματος. «Μας εκπλήσσει ότι η έντονη ατμοσφαιρική ρύπανση επιδρά στην εξέλιξη του εμφυσήματος με τον ίδιο τρόπο όπως το κάπνισμα,...

Έμφραγμα και εγκεφαλικό επεισόδιο: Η φαινομενικά αθώα πρωτεΐνη που υπερδιπλασιάζει τον κίνδυνο
Τα υψηλά επίπεδα μιας πρωτεΐνης που εκκρίνεται μετά από προπόνηση υψηλής έντασης ενδέχεται να αποτελούν δείκτη πρόβλεψης του κινδύνου εμφράγματος ή εγκεφαλικού επεισοδίου εντός των επόμενων ετών σύμφωνα με νέα έρευνα. Σε αυτό το συμπέρασμα κατέληξαν Ευρωπαίοι ερευνητές σε δημοσίευση της μελέτης τους στο Circulation. Στη μελέτη οι επιστήμονες εξέτασαν 725 ηλικιωμένους ανθρώπους που συμμετείχαν σε ένα περίπατο διάρκειας οκτώ ωρών στην Ολλανδία. Οι περιπατητές έδωσαν δείγματα αίματος πριν και αμέσως...

Bipaddle Pectoralis Major Myocutaneous Flap for Single Stage Reconstruction of Oromandibular Defects
Abstract Reconstruction of full thickness defects after resection of oral cancer is a challenge. Although microvascular free flaps are considered the first choice, their use is limited in the developing regions by availability of resources and the expertise. In this study, we have presented our experience with the use of bipaddle pectoralis major myocutaneous (PMMC) flap as a single stage reconstruction option for defects of the oral cavity. After undergoing resection of oral cancer,...

Tone burst electrocochleography disproves a diagnosis of Meniere’s disease treated aggressively
Abstract Reliable confirmation of the presence or absence of endolymphatic hydrops is essential to avoid confusing vestibular migraine with Meniere’s disease. MRI inner ear imaging is a promising new method to confirm hydrops, avoiding both unnecessary invasive or destructive inner ear treatments, but it is not universally available. Tone burst electrocochleography is an older simple, quick, safe, and sensitive test that is potentially available, with existing (or minorly upgraded)...

Infection Rates After Microlaryngeal and Open Phonosurgery: The Role of Postoperative Antibiotics
Objective Although it is known that the airway has bacterial contamination that seeds the surgical site during microlaryngeal surgery, literature on the use of postoperative antibiotics is lacking. We performed a retrospective analysis of open phonosurgical and phonomicrosurgical cases at a single institution to assess whether use of postoperative antibiotics impacts the incidence of surgical site infections (SSI). Methods In this retrospective cohort study, we reviewed 228 phonomicrosurgery...
