ABSTRACT

OBJECTIVES: The objectives of this study were to: (1) determine the prevalence of otitis media with effusion in patients with nonsyndromic craniosynostosis; (2) determine the prevalence of hearing loss in patients with nonsyndromic craniosynostosis; and (3) identify potential patterns and outcomes in patients with nonsyndromic craniosynostosis. METHODS: A retrospective chart review was conducted at 2 academic institutions, St Christopher's Hospital for Children and SUNY Upstate Medical University, from January 2015 through August 2018, to identify patients having nonsyndromic craniosynostosis with a concurrent diagnosis of otitis media and/or hearing loss. The demographic data and categorical variables were analyzed using descriptive statistics and chi-square testing, respectively. RESULTS: In the entire cohort of patients (N = 113, age range 0-123 months), 36% had otitis media with effusion on either history, physical examination, tympanometry, and/or imaging. Half (50%) of patients with coronal synostosis had otitis media with effusion compared to sagittal (40.7%), metopic (26.3%), multiple (25%), and lambdoid (0%). However, these differences were not statistically significant (P = .190). Most patients had normal hearing (91%), while a minority had either conductive (7%) or sensorineural (2%) hearing loss. CONCLUSION: The presence of otitis media in our cohort of patients with nonsyndromic craniosynostosis appears to be at the upper limit of normal when compared to historical rates in normocephalic children. Synostosis subtype did not appear to predict the presence of otitis media. Only 9% of patients with nonsyndromic craniosynostosis were found to have a hearing loss.

ABSTRACT

Purpose The first purpose of this study was to investigate and compare the short-term effects after a semi-occluded vocal tract (SOVT) therapy session consisting of straw phonation (SP) in air or water on vocal fold vibration and supraglottic activity of adult patients with voice disorders, visualized with strobovideolaryngoscopy (SVL). The second purpose of this study was to investigate and compare immediate changes in the patients' vocal fold vibration and supraglottic activity during SP in air or water, visualized with SVL. Methods Twelve adult patients with voice disorders (eight women and four men, mean age 52 years) were assigned randomly to one of two study groups: SP in air or SP in water. Immediately before and after a therapy session of 15 min, participants underwent a rigid SVL to determine the short-term effects of the SP session. At the posttherapy examination, flexible SVL while performing SP was added to determine the effects occurring during SP. The visual-perceptual ratings were performed blindly and in random order by three laryngologists, using the Voice-Vibratory Assessment with Laryngeal Imaging rating form for stroboscopy. ResultsShort-term effects after SP: After the SP-in-air session, the supraglottic mediolateral compression decreased significantly. The SP-in-water session led to significantly increased left vibrational amplitude. Immediate effects during SP: During SP in air, a significantly increased left amplitude and mucosal wave, and significantly decreased mediolateral supraglottic activity, were found. SP in water tended to decrease the vibrational amplitude during performance of the task. A trend toward higher anteroposterior supraglottic compression was observed during both SP in air and water, being more prominent in the latter. Conclusion SP in air led to less false vocal fold adduction and consequently less hyperfunction. The small increment in anteroposterior supraglottic activity during SP in air and water might be related to epilarynx narrowing, an economic phenomenon associated with SOVT exercises. The effects on vibrational amplitude were rather ambiguous. The small reduction in amplitude during SP in water is expected to diminish vocal fold impact stress and therefore creates an ideal basis for voice therapy. The increment in amplitude and mucosal wave during SP in air might indicate insufficient supraglottic pressure to obtain the favorable effects of semi-occlusion. Whether or not the rise in amplitude after the SP-in-water session is due to voice efficiency or voice fatigue remains unknown. Future larger-scale investigation in subgroups of voice patients is needed to explore these hypotheses.

ABSTRACT

BACKGROUND: The objective of this trial was to demonstrate the clinical efficacy and safety of topical cocaine as part of the effort to gain regulatory approval from the United States Food and Drug Administration. METHODS: This phase III, randomized, prospective, double-blind, multicenter, single-dose, placebo- and dose-controlled, parallel-group study aimed to evaluate the safety and efficacy of topical intranasal cocaine (RX0041-002). A total of 925 subjects were screened and a total of 648 subjects were randomized: 95 to placebo; 275 to 4% RX0041-002; and 278 to 8% RX0041-002. Efficacy was assessed with subjective pain intensity scores using the visual numeric rating scale and objectively using the von Frey filament test. Adverse events (AEs), vital signs, Holter monitoring, nasal irritation on visual examination, and smell assessment were recorded. The placebo and experimental groups were compared using a two-tailed Fisher's exact test. RESULTS: Topical 4% and 8% cocaine achieved significant subject analgesia, the primary efficacy endpoint. Both doses were safe and well-tolerated, with a safety profile similar to placebo. In the 4% and 8% groups, headache (1.5% and 2.5%, respectively), epistaxis (0.7% and 1.1%), and anxiety (0.7% and 0%) were the only AEs reported by >1 subject. No cardiovascular AEs, serious AEs, or deaths occurred. A higher percentage of subjects in the 4% and 8% groups compared with the placebo group had a modest increase in either systolic or diastolic blood pressure. CONCLUSION: Topical 4% and 8% cocaine is an effective anesthetic that can be safely administered for nasal procedures.

ABSTRACT

Clinicians employ various modalities in order to achieve temporal augmentation; however, no literature comprehensively describes these methods or provides perspective on available options. Understanding the available methodologies for cosmetic temporal augmentation allows for improved patient satisfaction with limited risk of complications. To synthesize the available literature on cosmetic temporal augmentation, including all available methodologies, patient satisfaction data, and complication rates, as well as to identify gaps in the available literature to encourage further research. A literature search was performed using the databases PubMed, Ovid Medline, Cochrane Library, and Web of Science. Using the key terms "temporal" or "temple" and "augmentation" or "rejuvenation," all article formats presenting primary literature data involving cosmetic temporal augmentation were included. Articles not presenting patient data or not discussing cosmetic indications were eliminated. A total of 12 articles were deemed appropriate for analysis. Of the 12 articles included, 6 (50%) evaluated filler techniques, 3 discussed fat grafting (25%), and 3 reviewed solid implant (25%) techniques. Eight (67%) of these were retrospective reviews, with the remaining being prospective trials (33%). All studies found high patient satisfaction rates and a small number of complications with their respective methodology. Several methods are employed for cosmetic temporal augmentation, including various types of injectable fillers, solid implants, and fat grafting, with all reporting successful satisfaction and complication outcomes. Further research is necessary to properly compare these modalities. Clinician discretion should guide procedural choice until future well-controlled studies are able to provide standardized outcomes.

ABSTRACT

Laboratories that study Drosophila melanogaster or other insects commonly use carbon dioxide (CO2) anaesthesia for sorting or other work. Unfortunately, the use of CO2 has potential unwanted physiological effects, including altered respiratory and muscle physiology, which impact motor function behaviours. The effects of CO2 at different levels and exposure times were examined on the subsequent recovery of motor function as assessed by climbing and flight assays. With as little as a five minute exposure to 100% CO2, D. melanogaster exhibited climbing deficits up to 24 hours after exposure. Any exposure length over five minutes produced climbing deficits that lasted for days. Flight behaviour was also impaired following CO2 exposure. Overall, there was a positive correlation between CO2 exposure length and recovery time for both behaviours. Furthermore, exposure to as little as 65% CO2 affected the motor capability of D. melanogaster. These negative effects are due to both a CO2-specific mechanism and an anoxic effect. These results indicate a heretofore unconsidered impact of CO2 anaesthesia on subsequent behavioural tests revealing the importance of monitoring and accounting for CO2 exposure when performing physiological or behavioural studies in insects.
