Klinisch-experimentelle Studie zur szintigraphischen Darstellung maligner Kopf-Hals-Neoplasien mit57Cobalt-Bleomycin
1975
Tumorscanning of malignomas and their metastatic nodules in head and neck is an enrichment of diagnostic possibilities. For the examination such substances can be used, which are tumoraffine and well to mark with a radio-isotope. Therefore we have marked the cytostatic drug Bleomycine with 57Co. Scans were performed with the Anger-Camera 4 to 6 hrs after intravenous injection of 1 mCi 57Co-Bleomycine. 60 patients with different malignomas have been examined, 46 with tumor-localization in head and neck, the others in thoraxabdomen. 34 (85%) of the head and neck malignomas could be demonstrated; 21 (81%) were squamous cell carcinomas, 13 (69%) sarcomas. The possibilities of this method are sh…
Head–Neck Cancer Delineation
2021
Head–Neck Cancer (HNC) has a relevant impact on the oncology patient population and for this reason, the present review is dedicated to this type of neoplastic disease. In particular, a collection of methods aimed at tumor delineation is presented, because this is a fundamental task to perform efficient radiotherapy. Such a segmentation task is often performed on uni-modal data (usually Positron Emission Tomography (PET)) even though multi-modal images are preferred (PET-Computerized Tomography (CT)/PET-Magnetic Resonance (MR)). Datasets can be private or freely provided by online repositories on the web. The adopted techniques can belong to the well-known image processing/computer-vision a…
Current state of dynamic surgery. A literature review.
2021
Background Recently, dental implant technology has been widely used for oral reconstruction. Dental implants are the treatment of choice for those patients with dental absences. An optimal implant placement is based on the prosthetic driven concept in order to achieve an aesthetic and functional restoration with a long-term prognosis. There are two types of guided implant surgery that are described in the literature: Static Guided Surgery (SGS) and Dynamic Guided Surgery (DGS). The aim of this study is to be aware of the current state of dynamic surgery and compare in the literature the discrepancies between planning and placement of dental implants. Material and Methods The study consists …
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…
Employment pathways and work-related issues in head and neck cancer survivors
2014
Background In this exploratory study, employment and psychological factors were investigated in head and neck cancer survivors with survivorship of ≥2 years. Methods Fifty-five head and neck cancer survivors ≤60 years old completed a survey including subscales from the Functional Assessment of Cancer Therapy (FACT) instrument, the Miller Behavioral Style Scale, the General Perceived Self-Efficacy Scale, the Patient Health Questionnaire-9 (PHQ-9), and the Hornheider–Fragebogen short version (HFB) measuring the need for psychological interventions. Exploratory analyses of associations to the employment status were performed. Results The rate of employed patients dropped from three-fourths of …
Red Ear Syndrome
2016
The Red Ear syndrome (RES) is an intriguing syndrome originally described for the first time nearly 20 years ago. RES is characterized by unilateral/bilateral episodes of pain and burning sensation of the ear, associated with ipsilateral erythema. RES episodes are indeed isolated in some patients, but they can occur in association with primary headaches, including in particular migraine in the developmental age. Although the underlying pathophysiological mechanisms are still uncertain, in the recent years the described comorbidities have aroused increasing interest because of possible clinical implications. Moreover, RES seems to be more often associated with clinical features of migraine p…
MORBILIDAD PSÍQUICA, EXISTENCIA DE DIAGNÓSTICO Y CONSUMO DE PSICOFÁRMACOS. DIFERENCIAS POR COMUNIDADES AUTÓNOMAS SEGÚN LA ENCUESTA NACIONAL DE SALUD …
2010
Background: Most of the studies on sychological distress in Spain have been conducted in small geographical areas or specific population groups. However, there are no studies that provide representative data for each Autonomous Community (AC). The objectives of this paper are to determine, both in Spain and in the AC, the prevalence of psychological distress, diagnosis, use of psychoactive medication, social support and self-perceived health, as well as to study the association between psychological distress and the rest of the variables. Methods: Cross-sectional study, using data from the 2006 National Health Survey, that was completed by 29,478 persons. Variables studied: sociodemographic…
Radiomics and radiogenomics in head and neck squamous cell carcinoma: Potential contribution to patient management and challenges
2021
Abstract The application of imaging biomarkers in oncology is still in its infancy, but with the expansion of radiomics and radiogenomics a revolution is expected in this field. This may be of special interest in head and neck cancer, since it can promote precision medicine and personalization of treatment by overcoming several intrinsic obstacles in this pathology. Our goal is to provide the medical oncologist with the basis to approach these disciplines and appreciate their main uses in clinical research and clinical practice in the medium term. Aligned with this objective we analyzed the most relevant studies in the field, also highlighting novel opportunities and current challenges.
Accuracy of computer-aided image analysis in the diagnosis of odontogenic cysts: A systematic review
2020
Background This study aimed to search for scientific evidence concerning the accuracy of computer-assisted analysis for diagnosing odontogenic cysts. Material and Methods A systematic review was conducted according to the PRISMA statements and considering eleven databases, including the grey literature. Protocol was registered in PROSPERO (CRD 42020189349). The PECO strategy was used to define the eligibility criteria and only studies involving diagnostic accuracy were included. Their risk of bias was investigated using the Joanna Briggs Institute Critical Appraisal tool. Results Out of 437 identified citations, five papers, published between 2006 and 2019, fulfilled the criteria and were i…
A case report of desmoplastic ameloblastoma
2010
Ameloblastomas are the most common benign neoplasm of odontogenic nature. Desmoplastic ameloblastoma (DA) was included in the World Health Organization Classification of Head and Neck Tumors (WHO-2005) as a variant of ameloblastoma with specific clinical, image, and histological features. This case report focuses on a DA which occurred in the mandible of a 25 year-old man. The main signals and symptoms included painless swelling with buccal expansion and tooth displacement. Panoramic and periapical radiographs and cone-bean computed to- mography demonstrated an image mimicking a benign fibro-osseous lesion. The lower border of the mandible was not involved, but tooth displacement could be o…
