Background Nasal preparation prior to flexible laryngoscopy is a common ENT practice. Co-phenylcaine is increasingly used because it is safe and has both anaesthetic and vasoconstrictive properties. Lidocaine 4% and epinephrine 1:1000 nasal packing is another method used in our department. Methods A prospective case series was performed on eighty-one patients requiring flexible laryngoscopy. Patients were enrolled into either a co-phenylcaine or a lidocaine/epinephrine packing group. Visual analogue scales (VAS) were used to record unpleasantness of nasal preparation and flexible laryngoscopy. Decongestion and ease of endoscope passage were recorded by the doctors. Results Bad taste was statistically significantly worse when using cophenylcaine for nasal preparation ( P = 0.001). However, there was no statistically significant difference in overall unpleasantness from nasal preparation or from subsequent flexible laryngoscopy between the two groups. There was no statistically significant difference in degree of decongestion or ease of endoscope passage between the two groups. Conclusion There is no statistically significant advantage of using cophenylcaine spray over non-proprietary lidocaine 4% and epinephrine 1:1000 nasal packing. However cost and bad taste is less with nasal packing.

Vertical ridge augmentation for long-term implant stability is difficult in severely resorbed areas. We examined the clinical, radiological, and histological outcomes of guided-bone regeneration using novel titanium-reinforced microporous expanded polytetrafluoroethylene (MP-ePTFE) membranes. Eighteen patients who underwent implant placement using a staged approach were enrolled (period: 2018–2019). Vertical ridge augmentation was performed in areas with vertical bone defects ≥ 4 mm. Twenty-six implant fixtures were placed in 14 patients. At implant placement six fixtures had relatively low stability. On cone-beam computed tomography, the average vertical changes were 4.2 ± 1.9 (buccal), 5.9 ± 2.7 (central), and 4.4 ± 2.8 mm (lingual) at six months after vertical ridge augmentation. Histomorphometric analyses revealed that the average proportions of new bone, residual bone substitute material, and soft tissue were 34.91 ± 11.61%, 7.16 ± 2.74%, and 57.93 ± 11.09%, respectively. Stable marginal bone levels were observed at 1-year post-loading. The residual bone graft material area was significantly lower in the exposed group (p = 0.003). There was no significant difference in the vertical height change in the buccal side between immediately after the augmentation procedure and the implant placement reentry time (p = 0.371). However, all implants functioned well regardless of the exposure during the observation period. Thus, vertical ridge augmentation around implants using titanium-reinforced MP-ePTFE membranes can be successful.

Summary Objective: To compare the effects of bandaging on immediate postoperative swelling using a modified Robert-Jones bandage after tibial plateau levelling osteotomy (TPLO) in dogs. Study design: Prospective case series. Methods: Dogs undergoing a TPLO were randomly placed into two groups. Group 1 received a modified Robert-Jones bandage postoperatively for a 24 hour period and Group 2 was not bandaged. Hindlimb circumference was measured at the level of the mid-patella, the distal aspect of the tibial crest, the midpoint of the tibial diaphysis and the hock. Measurements were recorded and compared in each group preoperatively and at 24 hours and 48 hours post-operatively. Interobserver variability was compared between the two observers. Results: There was no significant difference in postoperative swelling, as measured by the percentage change in circumference, between bandaged and unbandaged operated limbs after the TPLO at 24 and 48 hours at any site. Some significant differences in measurement at particular sites were observed between the two different observers, but there was a significant linear correlation at all sites between observers. The observer with the least experience consistently had slightly higher measurements at these sites. Clinical relevance: The use of a modified Robert-Jones bandage after TPLO did not prevent statistically significant postoperative swelling, and thus may not be indicated for this purpose. Postoperative bandages placed to control swelling after other small animal orthopaedic procedures should be evaluated individually for efficacy.

Purpose: A 6-month evaluation of the topographic and biomechanical changes induced by corneal collagen cross-linking (CXL) in keratoconic eyes using Pentacam and Corvis ST. Design: Longitudinal prospective case series. Methods: In this study, 67 eyes of 67 patients with progressive keratoconus (KCN) treated with “Epithelium-off” CXL were evaluated. Patients with stages 1 or 2 of KCN and a corneal thickness of at least 400 μm at the thinnest point were included. Standard ophthalmologic examinations were carried out for all patients. The topographic and biomechanical measurements of the cornea were obtained by Pentacam (Oculus Optikgeräte GmbH, Wetzlar, Germany) and Corvis ST (Oculus Optikgeräte GmbH, Wetzlar, Germany) preoperatively and 6-month postoperatively. Results: The mean age of the participants was 21.68 ± 4.23 years. There was significant difference in mean spherical equivalent (SE) before and 6 months after CXL. Uncorrected and best corrected visual acuity improved postoperatively, although not statistically significant. The mean and maximum keratometry showed a significant decrease 6 months after CXL (0.93 ± 0.38 D and 1.43 ± 0.62 D, respectively p < 0.001). Among Corvis ST parameters, first applanation length and velocity (AL1 and AV1) showed statistically significant changes. The radius at highest concavity changed significantly (0.13 ± 0.37 mm mean increase after CXL; p < 0.001). A significant increase was observed in stiffness parameter A1 (SP-A1; p < 0.001) and significant decreases were noted in integrated radius (IR) and deformation amplitude ratio (DAR; p < 0.001). Conclusion: Analyzing biomechanical changes after corneal cross-linking can provide basis for efficient KCN treatment. Corvis ST parameters demonstrated changes in corneal biomechanical characteristics indicative of stiffing after CXL.

Background. Demonstrating differences between euthymic bipolar subjects and healthy controls in response to positive (happy) mood induction may help elucidate how mania evolves. This pilot study evaluates the Go task in a reward paradigm as a method for inducing a happy mood state and compares the response of euthymic bipolar subjects and healthy controls.Method. The Sense of Hyperpositive Self Scale, the Tellegen positive and negative adjectives, the Global-Local task and a visual analogue scale for measuring positive affect were administered to 15 euthymic bipolar subjects and 19 age-and-sex-matched healthy control subjects before and after they had performed the Go task in a reward paradigm.Results. Significant differences were found between subjects and controls on several measures at each time-point but there were no differences across the groups across time except for the visual analogue scales, where subjects had a more sustained duration in self-reported happiness compared with controls.Conclusions. This pilot study has shown that a positive affect can be induced in bipolar subjects and controls which can be demonstrated by changes in scores on several tasks. However, only the visual analogue scales showed a significant difference between cases and controls over time. Such tests may prove valuable in furthering understanding about the evolution of manic mood states.

This study aimed to investigate the effects of varying midsole hardness on center of pressure (COP) and perceived stability during basketball-specific tasks, as well as the correlation between COP and perception measurements. A total of 20 male basketball players performed 45° cutting and layup while wearing basketball shoes with soft and hard midsoles. COP trajectories were obtained from the Pedar insole system. Stability perceptions at the forefoot and rearfoot were assessed using 150-mm visual analogue scales. Results indicated greater COP mediolateral deviations in soft midsole compared with hard midsole during layup (soft: 16.6 [4.7] mm, hard: 15.8 [4.6] mm, P = .03) but not 45° cutting (soft: 15.7 [5.9] mm, hard: 15.8 [5.6] mm, P = .60). While 16 out of 20 participants preferred soft midsole, no significant difference in visual analogue scale ratings was found between shoes for both tested movements. There was no significant correlation between COP and perceived stability during layup or 45° cutting. In conclusion, midsole hardness of basketball shoes did not consistently affect mediolateral stability of the foot during 45° cutting and layup. Subjective perception alone cannot be used to indicate mediolateral deviation of the foot when executing basketball-specific maneuvers.

Purpose: To evaluate the extent to which rebound tonometry affects corneal surface properties and preoperative corneal measurements. Setting: Four cornea specialty private practices. Design: Prospective case series. Methods: Visual acuity testing, corneal topography, keratometry, and grading of corneal staining were performed on both eyes of 60 randomly selected, previously scheduled patients. Technicians then performed rebound tonometry on one randomly selected eye only. Immediately following, intraocular pressure measurement, corneal topography, keratometry, and corneal staining were repeated on both eyes. Results: None of the 60 study eyes developed increased staining scores following intraocular pressure testing with the Icare ic100. For corneal staining, mean keratometry, and total corneal cylinder, no statistically significant difference was found from the first measurement to the second measurement between the study eyes and control eyes. Conclusion: Rebound tonometry with the Icare ic100 may be used on any patient at any time during the exam without affecting the results of other tests, allowing clinicians to test intraocular pressure prior to preoperative cataract or refractive surgery measurements on the same day. This may allow for significant improvement in patient flow in the office and save patients from the cost and time of extra visits.

Purpose: To investigate the differences in surgical maneuvers between vitreoretinal fellows and experienced vitreoretinal surgeons (attendings) when performing internal limiting membrane (ILM) peel during macular hole (MH) surgery and repair. Methods: Prospective case series. Macular hole surgeries performed by fellows and attendings at St Michael’s Hospital (Toronto, Canada) were recorded during a 12-month period. Evaluation of recordings was masked. Total peel time (TPL) in seconds, total movement attempts initiating and extending ILM flaps, intrasurgical complications, and surgical efficiency (ratio of approaches leading to case progression to total approaches) were quantified. Results: A total of 145 surgeries were evaluated; 44 met inclusion and exclusion criteria. Of the 44 cases, 25 were performed by fellows and 19 by attendings. Mean TPL was shorter for attendings (336 vs 506 seconds, P = .0032). Attendings had a lower average total movement attempts (32.2 vs 43.2, P = .045) and average flap initiation attempts (16.1 vs 23.3, P = .042). Surgical efficiency was better for attendings (45% vs 37% of approaches led to case progression, P = .038). There was no significant difference between groups in total flap extension attempts or intrasurgical complications. Conclusions: Compared to fellows, attendings peel ILM in MH surgery faster, more efficiently with a lower number of flap initiation attempts and total movements.

A multicentre, parallel group hospital study was carried out in 190 subjects with insomnia to compare the efficacy, incidence of hangover and the side-effects of loprazolam and nitrazepam. Following 2 nights single-blind phase on placebo, loprazolam (1·0 mg), nitrazepam (5·0 mg) or placebo was administered double-blind for 7 consecutive nights. Visual analogue scales and questions were used to rate efficacy. There was no statistically significant difference between loprazolam and nitrazepam for ‘ease of getting to sleep’, ‘restfulness of sleep’ and ‘depth of sleep’. Like nitrazepam, loprazolam diminished the number of periods of wakefulness and made it ‘easier to get to sleep again’. Subjective evaluation showed that hangover was not a feature of loprazolam. It did not affect morning alertness and patients thought they had improved balance and co-ordination while on this drug. These findings are in keeping with the evidence of other workers who have shown only minimal psychomotor impairment, if any, with loprazolam (1·0 mg). There was no statistically significant difference between treatments with respect to frequency or incidence of side-effects.
