Abstract Purpose We aimed to evaluate the feasibility and utility of intraoral ultrasound as a real-time guidance technique in trans-oral robotic surgery (TORS). Methods We report our early experiences of radiologist-operated intraoral ultrasound during TORS, providing information on tumour margin and important adjacent structures. Resection specimens...
Abstract Background Dental implants are commonly used for replacement of missing teeth. Despite the published data highlighting the high success rate of dental implants, failures do occur. Some of these failures are believed to be a result of bacterial contamination at the site of implant insertion. Various antibiotic regimens have already been suggested to prevent failure due to infection. ...

The aim of this study was to describe the steps of a minimally invasive surgical technique used to perform a proportional intraoral condylectomy with a three-dimensionally (3D) printed cutting guide. The technique consists of two steps: virtual surgical planning and intraoral condylectomy. During virtual surgical planning, the mandibular ramus was measured bilaterally, the height of the proportional condylectomy was planned virtually, and a cutting guide was 3D printed. In the intraoral condylectomy,...

Researchers have revealed the evolutionary history of the crown-of-thorns starfish -- a predator of coral that can devastate coral reefs. Their findings shed light on how the populations of these starfish have changed over time and could potentially help reduce their ecological destruction.
Large blocks of 'plug and play' genes play a super-sized role in adaption-and may help fill lingering gaps in Darwin's theories.

Several species of fish have adapted to harsh environments using the same mechanism, which brings to question evolutionary chance, according to a new study.
Some animals fake their body size by sounding 'bigger' than they actually are. Researchers studied 164 different mammals and found that animals who lower their voice to sound bigger are often skilled vocalists. Both strategies -- sounding bigger and learning sounds -- are likely driven by sexual selection, and may play a role in explaining the origins of human speech evolution.

Abstract Purpose Cognitive functioning is increasingly investigated for its prognostic value in glioblastoma (GBM) patients, but the association of cognitive status during early adjuvant treatment with survival time is unclear. The aim of this study was to determine whether cognitive performance three months after surgical resection predicted survival time, while using a clinically intuitive time ratio (TR) statistic. ...
Abstract Purpose Understanding the topographic-anatomical patterns of brain tumors has the potential to improve our pathophysiological understanding and may allow for anatomical tailoring of surgery and radiotherapy. This study analyzed topographic-anatomical patterns underlying neuroepithelial tumors, primary CNS lymphoma and metastases. Methods Any...

Abstract Dermal filler injections are common cosmetic procedures and are growing in popularity. While frequently performed, dermal filler injections carry a risk of adverse events including vascular compromise and foreign body granulomas. Here, we discuss an unusual case of a patient with a history of dermal filler injections presenting with a parotid mass and an eyebrow mass requiring surgical resection. This case demonstrates the risk of delayed granuloma formation many years...
Abstract The first detailed description of calcifying epithelial odontogenic tumor (CEOT) are ascribed to Jens Pindborg, but this tumor was described some years previously. Subsequently, CEOT was included in the 1971 WHO classification of odontogenic tumors and a since then number of variants have been described, which have added confusion to the diagnostic criteria. We aimed to survey the literature on the variants of CEOT, in parallel with a review of our single institution experience...

Abstract This article is the second of a two-part series on intracranial calcification in childhood. In Part 1, the authors discussed the main differences between physiological and pathological intracranial calcification. They also outlined histological intracranial calcification characteristics and how these can be detected across different neuroimaging modalities. Part 1 emphasized the importance of age at presentation and intracranial calcification location and proposed a comprehensive...

Acute asthma exacerbations account for 750,000 pediatric emergency department (ED) visits, 200,000 hospitalizations and 5.2 billion in excess healthcare costs in the US annually.1 Current ED treatment of acute exacerbations is based on severity at initial presentation as determined by clinical scoring tools, which are limited by subjectivity and poor association with actual airway function.2 Traditional methods to objectively assess lung function, including spirometry and peak flow, are not feasible...

Η έναρξη θεραπείας με μια αγωγή βασισμένη στη μετφορμίνη αποδεικνύεται η ιδανική επιλογή για ασθενείς με διαβήτη τύπου 2, οι οποίοι δεν έχουν λάβει προηγούμενη αντιδιαβητική αγωγή και διατρέχουν χαμηλό κίνδυνο εμφάνισης καρδιαγγειακών νόσων. Δεν υπάρχουν ωστόσο επαρκή στοιχεία που να καθιστούν τη συγκεκριμένη θεραπεία κατάλληλη για διαβητικούς με υψηλά ποσοστά καρδιαγγειακού κινδύνου. Τα ευρήματα της μελέτης δημοσιεύτηκαν στο Annals of Internal Medicine. Επιστημονικά δεδομένα έχουν αποδείξει πως...

Μια καινοτόμος θεραπεία για ασθενείς με λοίμωξη από Clostridium difficile που βασίζεται στη μεταμόσχευση βακτηρίων του εντέρου, αποτελεί, καθώς έδειξε μια νέα μελέτη του Ηνωμένου Βασιλείου, μια πιο αποτελεσματική και οικονομική εναλλακτική σε σχέση με τη χρήση αντιβιοτικών. Η λοίμωξη από Clostridium difficile αποτελεί λοίμωξη του εντέρου, η οποία συνήθως προσβάλλει άτομα που έχουν νοσηλευτεί πρόσφατα σε νοσοκομείο, ασθενείς με υποκείμενα νοσήματα ή ηλικίας άνω των 65 ετών. Σχεδόν το 30% των ασθενών...

Εδώ και 66 εβδομάδες, ο ασθενής δεν φαίνεται να έχει πια στο αίμα του ίχνη λοίμωξης: Ούτε τον ίδιο τον ιό, ούτε αντισώματα εναντίον του. Όμως, τα αποτελέσματα θεωρούνται προκαταρκτικά και θα πρέπει να επιβεβαιωθούν. ...

Το ξενύχτι βλάπτει σοβαρά την υγεία των εφήβων και συγκεκριμένα την αναπνευστική υγεία, προειδοποιεί νέα έρευνα που δημοσιεύτηκε στο ERJ Open Research. Πρόκειται για την πρώτη μελέτη που διερεύνησε ειδικώς τη σχέση των ωραρίων του ύπνου με την αναπνευστική υγεία σε εφήβους, και η οποία έδειξε πως όσοι συνηθίζουν να ξενυχτούν και να ξυπνούν πιο αργά στη διάρκεια της ημέρας κινδυνεύουν περισσότερο από αλλεργίες και άσθμα. Σύμφωνα με τον Δρ. Subhabrata Moitra από το Τμήμα Πνευμονικής Ιατρικής στο...

Έχει περάσει μεγάλο χρονικό διάστημα από την ημέρα που η χρήση μάσκας κατέστη υποχρεωτικό μέτρο προστασίας και αποφυγής διασποράς του νέου κορωνοϊού. Και ενώ η χρήση της είναι μείζονος σημασίας για την υγεία μας, ο ερεθισμός του δέρματος έπειτα από αρκετό χρόνο με τη μάσκα στο πρόσωπο παραμένει απειλή. Η αντίδραση του δέρματος μπορεί να παρουσιαστεί με εξανθήματα ή με τον ερεθισμό από την τριβή με το ύφασμα. Όπως επισημαίνουν οι ειδικοί, η μη χρήση της μάσκας δεν αποτελεί λύση.

AbstractThis case describes a 9-year-old male who presented to general surgical clinic with a 3-year history of persistent natal cleft swelling, previously unsuccessfully treated as a pilonidal abscess in the community with multiple courses of antibiotics. In clinic, a 50 × 30-mm soft tissue swelling was found in the natal cleft and a clinical diagnosis of a pilonidal cyst was made. A cream-coloured solid mass measuring 50 × 35 × 30 mm was subsequently excised under general anaesthetic, with specialist...
AbstractAcute pancreatitis may present with a myriad of clinical and radiological manifestations. Assessment of the severity and prognosis of the disease is often based on clinical features, laboratory analysis and computer tomography (CT) scans; however, the predictive value of CT is not 100% accurate. We report herein a case with an especially rare sequence of clinical events, manifesting as a septic fluid collection within the inguinal canal that was misdiagnosed as an inguinal hernia on CT imaging....
AbstractTreatment of stage II–IV nonseminomatous testicular germ cell tumors (NSTGCTs) consists of cisplatin-based combination chemotherapy and, when present, resection of residual retroperitoneal tumor mass (RRTM) by conventional laparotomy or laparoscopy. In case of a retroperitoneal recurrence, a second conventional or laparoscopic procedure may be challenging. A case of late relapse after prior conventional resection of a RRTM and tailor-made surgical management with a posterior retroperitoneoscopic...
