Purpose: Edema is a frequent clinical observation after chemoradiation treatment (XRT) for oral/oropharyngeal cancer (O/OP Ca). Our aim is to quantify within-subject measures of edema from pre- and post-XRT videofluoroscopy (VF) and to explore the relationship between edema and aspiration. Method(s): Fourty patients (24 male; ages 38-76) diagnosed with O/OP Ca received radiotherapy (70 Gy, 7 weeks) and 3 weekly doses of cisplatin. VF was completed pre- and again 4 weeks post-XRT. 3 pixel-based measures captured edema from a post-swallow rest frame of a 5 ml thin liquid bolus: posterior pharyngeal wall (PPW) thickness, pharyngeal area (PA) and vallecular space (VS). Worst PAS scores categorized subjects as unsafe (>=3) or safe (<=2). Repeated measures ANOVAs were used to explore the relationship between the edema measure (pre- vs post-XRT) and swallow safety (safe vs unsafe). Result(s): The proportion of patients with unsafe swallows increased from 8/40 pre-XRT to 14/40 post-XRT, though this was not significant (p = 0.2). A significant main effect was confirmed in reduced PA post-XRT [F = 29.9, p = 0.00] and a trending increase was observed for PPW [F = 3.2, p = 0.08]. However, no significant differences between unsafe vs safe groups were found for any edema variables. Conclusions (Including Clinical Relevance): The data confirm that post-XRT edema can be quantified on VF by measuring PPW thickness and PA. A significant worsening in edema measures in individuals with unsafe compared with safe swallows was not detected. The data was limited by a low proportion of post-XRT aspirators. Future analyses will examine the relationship between edema and residue

Introduction No evidence-based guidelines exist for preventive dental care before ra-diation therapy (RT) in head and neck cancer (HNC) patients. An ongoing multi-center, prospective cohort study, Clinical Registry of Dental Outcomes in HNC patients (OraRad) (1U01DE022939-01), is addressing this knowledge gap. Objectives Evaluate dental disease and associated factors pre-RT. Methods OraRad enrolls patients at six U.S. clinical centers pre-RT; follows them every 6 months for 2 years post-RT with primary outcome of tooth loss. Calibrated examiners assess caries and periodontal disease using validated scales and standardized procedures. Results Baseline measures were reported for 356 participants with mean (SD) age 59.9 (11.0) years; 77% male. Pre-RT dental disease parameters (means) include: number of teeth 22.9; decayed, missing, filled surfaces (DMFS) 33.3 with 1.6 decayed surfaces; clinical attachment level 1.8mm; and probing depth 2.4 mm with 13.5% of tooth sites >=4mm. Participants with at least a high school diploma had more teeth and fewer tooth sites with PD >=4mm compared to those with less education. Patients who received routine dental care had more total teeth pre-RT vs. those without (24.0 vs. 19.8, respectively). We found 37.2% of patients had at least 1 decayed surface and 47.4% had a least one tooth with a probing depth >4mm. Conclusions A high proportion of patients have dental disease at the start of RT for HNC. Observing dental outcomes post-RT, OraRad has the potential to determine the risk of dental disease at the start of RT and determine the best treatment recommendations for HNC patients pre-and post-RT

Introduction Radiation Therapy (RT) for Head and Neck Cancer (HNC) can cause significant oral complications. However, modern techniques such as Intensity Modulated RT (IMRT) may reduce their incidence/severity. Objectives To assess severity of oral complications 6 months after modern RT for HNC. Methods OraRad is an ongoing 6-center prospective cohort study. Oral outcomes are evaluated before start of RT (baseline), and 6, 12, 18, 24 months after RT. For this analysis, we compared baseline vs. 6 month data using mixed linear models for continuous measures and generalized estimating equations for categorical measures. Data are presented as outcome mean (SD, number of subjects), unless otherwise stated. Results Stimulated whole salivary flow declined from 1.09 ml/min (0.67, 354) at baseline to 0.47 (0.47, 216) at 6 months (p < 0.0001). Maximal mouth opening reduced from 45.58 mm (10.40, 371) to 42.53 (9.52, 208) (p < 0.0001). 17 of 203 subjects (8.4%) had persistent oral mucositis at 6 months. Overall oral health-related quality of life score (1-4 scale) worsened from 1.48 (0.42, 371) to 1.86 (0.47, 211) (p < 0.0001). Contributing to this decline were subject-reported negative changes related to swallowing solid food, choking when swallowing, opening the mouth wide, dry mouth, sticky saliva, smell, and taste (p < 0.0001). At 6 months, there was greater frequency of using dental floss, and greater proportion using supplemental fluoride (p < 0.0001). Conclusions Despite use of IMRT, HNC patients continue to suffer significant oral complications of cancer therapy, with negative impact on oral health, function, and quality of life

The mal de debarquement syndrome (MdDS) is a movement disorder, occurring predominantly in women, is most often induced by passive transport on water or in the air (classic MdDS), or can occur spontaneously. MdDS likely originates in the vestibular system and is unfamiliar to many physicians. The first successful treatment was devised by Dai et al. (1), and over 330 MdDS patients have now been treated. Here, we report the outcomes of 141 patients (122 females and 19 males) treated 1 year or more ago. We examine the patient's rocking frequency, body drifting, and nystagmus. The patients are then treated according to these findings for 4-5 days. During treatment, patients' heads were rolled while watching a rotating full-field visual surround (1). Their symptom severity after the initial treatment and at the follow-up was assessed using a subjective 10-point scale. Objective measures, taken before and at the end of the week of treatment, included static posturography. Significant improvement was a reduction in symptom severity by more than 50%. Objective measures were not possible during the follow-up because of the wide geographic distribution of the patients. The treatment group consisted of 120 classic and 21 spontaneous MdDS patients. The initial rate of significant improvement after a week of treatment was 78% in classic and 48% in spontaneous patients. One year later, significant improvement was maintained in 52% of classic and 48% of spontaneous subjects. There was complete remission of symptoms in 27% (32) of classic and 19% (4) of spontaneous patients. Although about half of them did not achieve a 50% improvement, most reported fewer and milder symptoms than before. The success of the treatment was generally inversely correlated with the duration of the MdDS symptoms and with the patients' ages. Prolonged travel by air or car on the way home most likely contributed to the symptomatic reversion from the initial successful treatment. Our results indicate that early diagnosis and treatment can significantly improve results, and the prevention of symptomatic reversion will increase the long-term benefit in this disabling disorder.

Purpose of Review: Treating malignant tumors of the anterior skull base (ASB) is a challenging task, involving complex surgery in an intricate anatomical space. The effective treatment of ASB tumors requires careful pretreatment evaluation and preoperative surgical planning by the skull base surgical team. Recent Findings: Review of the available literature demonstrates that the gradual refinement of imaging and surgical techniques, as well as improvement in reconstructive procedures, has dramatically improved patient outcomes and reduced morbidity and mortality. Furthermore, multicenter collaborations have provided higher quality evidence regarding disease behavior and treatment efficacy and safety. Summary: Current and past review of the literature continues to demonstrate the need for future investigation. High-quality evidence-based medicine is still lacking in the field of skull base surgery, and well-planned collaborative studies are needed in order to consolidate our understanding of disease behavior and treatment strategies.

Describe age-related barriers to pain assessment and key aspects of the assessment process. 2. Identify benefits and risks associated with commonly prescribed analgesic medications for the treatment of later life pain. DISCLOSURE STATEMENT Neither the planners nor the authors have any conflicts of interest to disclose. The current article addresses pharmacological treatment issues regarding the management of persistent pain in later life, which is a worldwide problem associated with substantial disability. Recommendations from guidelines were reviewed and data are presented regarding the benefits and risks of commonly prescribed analgesic medications. The evidence base supports a stepwise approach with acetaminophen as first-line therapy for mild-to-moderate pain. Oral nonsteroidal anti-inflammatory drugs are not recommended for long-term use. In properly selected older patients, opioid drugs should be considered if pain is not adequately controlled. Careful surveillance to monitor for benefits and harms of therapy is critical, given that advancing age increases risk for adverse effects. Key aspects of the pain care process that nurses routinely engage in are covered, including conducting pain assessments prior to initiating therapy, addressing barriers to effective pain care, educating patients and family members about the importance of reducing pain, discussing treatment-related risks and benefits, and formulating strategies to monitor for treatment outcomes. Finally, a case is presented to illustrate issues that arise in the care of affected patients. [Journal of Gerontological Nursing, 42(12), 49-57.].

OBJECTIVE A randomized trial that compares clinical outcomes following microsurgery (MS) or stereotactic radiosurgery (SRS) for patients with small- and medium-sized vestibular schwannomas (VSs) is impractical, but would have important implications for clinical decision making. A matched cohort analysis was conducted to evaluate clinical outcomes in patients treated with MS or SRS. METHODS The records of 399 VS patients who were cared for by 2 neurosurgeons and 1 neurotologist between 2001 and 2014 were evaluated. From this data set, 3 retrospective matched cohorts were created to compare hearing preservation (21 matched pairs), facial nerve preservation (83 matched pairs), intervention-free survival, and complication rates (85 matched pairs) between cases managed with SRS and patients managed with MS. Cases were matched for age at surgery (+/- 10 years) and lesion size (+/- 0.1 cm). To compare hearing outcomes, cases were additionally matched for preoperative Class A hearing according to the American Academy of Otolaryngology-Head and Neck Surgery guidelines. To compare facial nerve (i.e., cranial nerve [CN] VII) outcomes, cases were additionally matched for preoperative House-Brackmann (HB) score. Investigators who were not involved with patient care reviewed the clinical and imaging records. The reported outcomes were as assessed at the time of the last follow-up, unless otherwise stated. RESULTS The preservation of preoperative Class A hearing status was achieved in 14.3% of MS cases compared with 42.9% of SRS cases (OR 4.5; p < 0.05) after an average follow-up interval of 43.7 months and 30.3 months, respectively. Serviceable hearing was preserved in 42.8% of MS cases compared with 85.7% of SRS cases (OR 8.0; p < 0.01). The rates of postoperative CN VII dysfunction were low for both groups, although significantly higher in the MS group (HB III-IV 11% vs 0% for SRS; OR 21.3; p < 0.01) at a median follow-up interval of 35.7 and 19.0 months for MS and SRS, respectively. There was no difference in the need for subsequent intervention (2 MS patients and 2 SRS patients). CONCLUSIONS At this high-volume center, VS resection or radiosurgery for tumors
