Overexpression of GLUT-1 is associated with resistance to radiotherapy and adverse prognosis in squamous cell carcinoma of the oral cavity
2006
This study tested the hypothesis that GLUT-1 is a marker of radioresistance in oral squamous cell carcinomas (OSCC). A GLUT-1 labeling index (LI) was determined by immunohistochemistry in 40 pretreatment OSCC biopsies. Radiation responses were categorized by histopathology of the resection specimens. Associations between the LI and radiation response, Kaplan-Meier survival estimates and Cox regression analysis for the variables GLUT-1, T-stage, N-stage and chemotherapy were examined. The median LI was 64.2% (range 14-100%). Tumors with65% of GLUT-1+cells were more resistant to radiation (p=0.023). Overall survival was higher (p=0.044) for subjects with low LI (median value) than those with …
Cachexia induces head and neck changes in locally advanced oropharyngeal carcinoma during definitive cisplatin and image-guided volumetric-modulated …
2015
Cancer cachexia is a syndrome characterized by weight loss (WL) and sarcopenia. Aim of the study was to assess the impact of cachexia on head and neck changes during definitive cisplatin and image-guided volumetric-modulated arc radiation therapy in a series of locally advanced oropharyngeal cancer.Volume variations of sternocleidomastoid muscle (SCM) were considered as surrogate of muscle changes related to sarcopenia. Two head and neck diameters, encompassing the cranial limits of II and III nodal levels (defined as 'head diameter' and 'neck diameter', respectively), were measured. All parameters were defined retrospectively by means of on-board cone beam computed tomography images at 1-8…
DNA measurements for monitoring chemotherapy in advanced head and neck carcinomas
1994
Background. Quantitative DNA measurements have demonstrated prognostic relevance in various malignancies, including head and neck cancer. The application of DNA measurements in monitoring and predicting the outcome of chemotherapy in treating patients with head and neck cancer was investigated. Methods. Twenty-five patients with advanced squamous cell carcinomas of the head and neck who underwent primary chemotherapy with three courses of cisplatin and 5-fluorouracil (5-FU) were examined in this study. Cytologic smears from the tumor site, as well as from normal mucosa, were taken before and 1 week after each course of chemotherapy. Quantitative DNA measurements were performed using an auto…
Methotrexate, Vinblastine, Epidoxorubicin, and Bleomycin as Second-Line Chemotherapy for Recurrent and/or Metastatic Squamous Cell Carcinoma of the H…
1994
Thirty evaluable patients with recurrent and/or metastatic squamous cell carcinoma of the head and neck region previously treated with cisplatin-based chemotherapy were treated with a combination of methotrexate, vinblastine, epidoxorubicin, and bleomycin as second-line chemotherapy. Besides surgery and/or radiotherapy all patients had previously received chemotherapy as induction therapy or as palliation for recurrent disease. Only 20% of patients achieved a partial objective response with a mean duration of 5.6 months (range 3.2-6.2), and 30% of patients had a stabilization of disease with a mean duration of 4.2+ months (range 3.8-6.0). Patients who responded had rhinopharyngeal carcinoma…
Short-term effects of kinesio taping in the treatment of latent and active upper trapezius trigger points : two prospective, randomized, sham-control…
2019
Este es el artículo que se ha publicado de forma definitiva en: https://www.nature.com/articles/s41598-019-51146-4 The presence of myofascial trigger points (MTrPs) is one of the most common causes of musculoskeletal problems and may lead to limited professional activity. Among the various treatment methods proposed for MTrPs, Kinesio Taping (KT) is a non-invasive, painless, and less time-consuming method with fewer side efects that has become widely used as a therapeutic tool in a variety of prevention and rehabilitation protocols. The aim of the study was to evaluate the immediate and short-term efcacy of the space correction KT technique in patients with latent or active MTrPs in the upp…
Efficacy of a proprioceptive exercise program in patients with nonspecific neck pain: a randomized controlled trial.
2020
BACKGROUND Nonspecific neck pain is associated with chronic pain, disability, reduced cervical mobility, postural control disorders and impaired proprioceptive control. AIM The aim of this study was to compare the effectiveness of two therapeutic exercise programs (i.e. cervical proprioception and cervical mobility) in reducing pain and disability in individuals with nonspecific neck pain. We further aimed to compare the effectiveness of the two treatments in improving pressure pain threshold, cervical range of motion and head repositioning accuracy. DESIGN This study was designed as a randomized controlled trial. SETTING This study took place in a private rehabilitation clinic. POPULATION …
Effects of botulinum toxin type A on vibration induced facilitation of motor evoked potentials in spasmodic torticollis.
2004
It has not been clarified if botulinum toxin (BTX) injection leads to muscle spindle dysfunction in man. This study aimed to test the hypothesis that BTX application reduces the facilitation of a magnetic evoked response (MEP).We used the vibration induced facilitation of an MEP of the sternocleidomastoid muscle (SCM) as a surrogate marker for muscle spindle function in 20 healthy subjects and 10 patients with idiopathic rotational torticollis in whom BTX was injected unilaterally.The increase in the amplitude and area of the MEPs in the clinically not affected and untreated SCM of the patients did not differ significantly from the controls. At baseline, the vibration induced increase in th…
Management of head and neck paragangliomas: review of 120 patients.
2008
Head and neck paragangliomas (PGL) are rare, mostly benign tumors. About 10% to 15% of PGL are caused by mutations in the succinate dehydrogenase genes B, C, or D and may appear multifocally.A retrospective review of 120 patients with 146 head and neck PGL, including 46 carotid body tumors (CBT), 13 vagal tumors, 55 jugulotympanic tumors (JTT), 25 tympanic tumors (TT) and 7 tumors in other locations are included. The internal carotid artery was preserved in 97.5% of CBT resections. Preservation of hearing was achieved in 92% of JTT and 88% of TT resections.According to our experience, the treatment of PGL must be individualized, taking into account the patient's age, medical condition, tumo…
Cytotoxic and genotoxic effects of electronic cigarette liquids on human mucosal tissue cultures of the oropharynx
2016
The popularity of electronic cigarettes (ECs) is rapidly growing and ECs are claimed to be an uncritically regarded alternative to conventional cigarettes. The mucosal tissue of the upper aerodigestive tract (UADT) is the first contact organ for xenobiotics such as liquids of ECs. The aim of this study is to investigate the bimolecular effects of e-liquids on human pharyngeal tissue cultures to evaluate whether e-liquids and their components present a risk factor for head and neck squamous cell carcinoma. Fresh tissue samples of healthy oropharyngeal mucosa were assembled into mucosal tissue cultures. Two fruit-flavored liquids (FLs), one tobacco-flavored liquid (TL) (all containing nicotin…
Bovine pericardium based non-cross linked collagen matrix for successful root coverage, a clinical study in human
2012
Abstract Introduction The aim of this study was to clinically assess the capacity of a novel bovine pericardium based, non-cross linked collagen matrix in root coverage. Methods 62 gingival recessions of Miller class I or II were treated. The matrix was adapted underneath a coronal repositioned split thickness flap. Clinical values were assessed at baseline and after six months. Results The mean recession in each patient was 2.2 mm at baseline. 6 Months after surgery 86.7% of the exposed root surfaces were covered. On average 0,3 mm of recession remained. The clinical attachment level changed from 3.5 ± 1.3 mm to 1,8 ( ± 0,7) mm during the observational time period. No statistically signifi…
