Prospective, randomized, controlled clinical trial of a novel matrix hemostatic sealant in patients with acute anterior epistaxis

OBJECTIVES: Floseal, a novel hemostatic sealant composed of collagen-derived particles and topical bovine-derived thrombin, is applied as a high-viscosity gel for hemostasis. This study is a prospective, randomized, controlled clinical trial of Floseal compared with nasal packing in patients with acute anterior epistaxis. STUDY DESIGN: Institutional review board-approved, prospective, randomized, controlled, nonblinded, crossover clinical trial. METHODS: Seventy consecutive patients presenting with acute anterior epistaxis were randomized to receive Floseal or nasal packing for control. Patients were crossed over to the other technique after two unsuccessful attempts of the first technique. Patients were seen in the clinic within 7 days for follow-up. Ten-point visual analogue scales were used to rank effectiveness (1 = ineffective, 10 = effective), physician technical ease (1 = difficult, 10 = easy), physician satisfaction (1 = unsatisfied, 10 = satisfied), patient discomfort during hemostasis (0 = none, 9 = unbearable), patient discomfort at follow-up office visit, and patient satisfaction. Additional data included need for subspecialist consultation to control bleeding, rebleeding rates within 7 days, and rebleeding at follow-up visit. RESULTS: Floseal (n = 35) was judged by physicians to be more effective than nasal packing (n = 35) at initial control of anterior epistaxis (9.9 vs. 7.7, P < .001). Physicians found Floseal to be easier to use (9.4 vs. 3.2, P < .001) and were more satisfied with Floseal (9.6 vs. 3.5, P < .001). Patients experienced less discomfort with Floseal than with nasal packing both at initial control (1.4 vs. 8.9, P < .001) and at follow-up visit (0.0 vs. 8.5, P < .001), and Floseal patients were more satisfied overall (9.1 vs. 2.9, P < .001). Fewer in-person otolaryngology consultations were requested for Floseal patients (8.6% vs. 31.0%, P < .05). Floseal patients experienced fewer rebleeding rates within 7 days (14% vs. 40%, P < .05). Rebleeding rates at follow-up visit were higher in the nasal packing than the Floseal group at time of packing removal (63% vs. 0%, P < .001). Eight (23%) patients were crossed over from the nasal packing group to the Floseal group when nasal packing was ineffective. One Floseal patient (3%, P < .05) was crossed over into the nasal packing group. There were no complications in either group. CONCLUSIONS: Floseal hemostatic sealant is a better tolerated, more effective, safe, and easy alternative to nasal packing in patients presenting with acute anterior epistaxis. Future studies may wish to evaluate Floseal's use in posterior epistaxis.     

Telehealth as an effective method of follow-up for pediatric post tonsillectomy patients

PurposeTo determine if pediatric patients can be safely and effectively managed postoperatively with nurse led telehealth communication.MethodsThis is a retrospective case series conducted at a tertiary academic medical center pediatric otolaryngology practice. Retrospective chart review was conducted on patients <18 years old who underwent tonsillectomy from January 2017 to December 2019. Patients were managed postoperatively with a telehealth communication on postoperative day (POD) 3–5 and again at 4–6 weeks. Patient demographics, satisfaction with follow-up, number of office visits, and postoperative complications were recorded.Results829 tonsillectomy patients were identified. Average patient age was 5.7 years (range 10 months-16 years). Successful contact was made with the patient's caregiver on POD 3–5 for 511 patients. 322 patients successfully completed 4–6 weeks telehealth follow-up. 292 patients (91 %) reported improvement in pre-operative symptoms at 4–6 weeks. Overall, 98 % of patients who completed telehealth follow-up were satisfied with this method and did not desire an additional office appointment. 62 patients (21 %) participated in an office follow-up in 2017, 54 patients in 2018 (19 %), and 36 patients (14 %) in 2019. Only 61 of these visits were routinely scheduled postoperative tonsillectomy office visits. 53 patients (6 %) had a postoperative tonsillectomy bleed and 31 patients (4 %) required return to the operating room for cauterization.ConclusionTelehealth is successful in reducing the number of post-tonsillectomy office visits for pediatric patients without a subsequent increase in complications. Reduction in office visits can lead to cost reduction and increased availability of pediatric otolaryngology appointments.     

Effectiveness of postoperative follow-up telephone interviews for patients who underwent adenotonsillectomy: a retrospective study

OBJECTIVE: To evaluate the effectiveness of follow-up telephone interviews and questionnaires after tonsillectomy and adenoidectomy. DESIGN: Cohort study and retrospective review of the outcomes of patients whose follow-ups were conducted by telephone interview. Patients were contacted 2 to 4 weeks after surgery; responses were recorded on a standardized postoperative questionnaire. SETTING: Tertiary pediatric hospital. PATIENTS: A total of 2554 consecutive patients who had undergone tonsillectomy, adenoidectomy, or both procedures and completed a follow-up telephone interview during the period of January 8, 2000, to September 23, 2004. MAIN OUTCOME MEASURES: Time to return to normal diet and activities, postoperative complications, pain management, postoperative visits, and caregiver's evaluation of the follow-up telephone survey. RESULTS: A total of 2554 patient outcomes were reviewed. The mean patient age was 5.9 years. Follow-up contact occurred a mean of 24.1 days after surgery. Of the surgical procedures performed, there were 1957 adenotonsillectomies, 235 adenoidectomies, and 362 tonsillectomies. At the time of follow-up, 2.7% of the patients had undergone an additional surgical procedure to treat postoperative bleeding, 96.9% had resumed eating a normal diet, and 96.2% had resumed normal activities. Bleeding from the nose or mouth was reported to have occurred at some point during the recovery period in 12.8%. On a pain scale of 1 to 10, a mean pain peak of 6.7 was reported. For most patients, pain was highest on the second day after surgery. The percentage of patients who had temporary voice change was 62.7%, and 15.4% had a follow-up clinic visit. Regarding caregivers, 99.5% reported being given instructions for postoperative care, and 98.8% reported that they felt well prepared to care for their child at home. There were no adverse events reported from surgical intervention. CONCLUSIONS: Compared with our previous experience with scheduled postsurgical clinic follow-ups, telephone interviews and standardized postoperative questionnaires pose no additional risk to patients. Considerable cost reduction and patient convenience were realized with a reduction of patient visits.     

Variables affecting treatment in benign paroxysmal positional vertigo

OBJECTIVE: To identify variables affecting outcome in patients with benign paroxysmal positional vertigo (BPPV) treated with canalith repositioning maneuvers. STUDY DESIGN: Retrospective review of patients at a tertiary vestibular rehabilitation center. METHODS: Variables identified for statistical analysis included method of diagnosis, age, sex, onset association with trauma, semicircular canal involvement, presence of bilateral disease, treatment visits, and cycles of canalith repositioning maneuvers per treatment visit. Multivariate statistical analysis using Pearson chi2, likelihood ratio, linear-by-linear association, and cross-tabulation tests were performed. RESULTS: Two hundred fifty-nine patients with BPPV who received treatment were identified from 1996 to 1998. Average follow-up time was 16.9 months. 74.8% required one treatment visit, 19.0% required a second treatment visit, and 98.4% were successfully treated after three treatment visits. The remainder required up to seven treatment visits for relief of symptoms. Variables affecting the number of treatment visits included bilateral disease or location of disease other than in the posterior semicircular canal. Patient age, sex, method of diagnosis, and onset association with trauma had no statistically significant impact. CONCLUSION: Patients with benign paroxysmal positional vertigo not located in a single posterior semicircular canal are more likely to require multiple visits for canalith repositioning.     

Intraoperative fluorouracil in endonasal laser dacryocystorhinostomy

BACKGROUND: Although endonasal laser dacryocystorhinostomy (ELDCR) offers many advantages compared with conventional techniques, postoperative scarring leading to occlusion of the rhinostomy is more common with ELDCR. OBJECTIVE: To investigate whether fluorouracil applied to the rhinostomy site intraoperatively has an effect on the outcome. PARTICIPANTS: We randomly allocated 155 consecutive patients (201 procedures) to a control group and a fluorouracil group. Patients and investigators were masked to the choice of treatment. METHODS: All patients underwent ELDCR. A pledget soaked in isotonic sodium chloride solution or 0.5-mg/mL fluorouracil, randomly allocated by the pharmacy, was applied to the rhinostomy site for 5 minutes at the time of surgery. Patients were followed up for 12 months and their symptoms were assessed at each visit. RESULTS: Among patients followed up for 12 months or longer, ELDCR procedures performed with topical application of fluorouracil to the rhinostomy site were successful in 65 (76%), compared with 52 (63%) for the control group. This was not statistically significant when patients who failed to attend follow-up at or after 12 months were not counted as successfully treated (P =.21, chi(2) test). Even if those who failed to attend for follow-up were counted as successes, the effect of fluorouracil did not reach significance at the.05 level (P =.08, chi(2) test). CONCLUSION: The topical application of fluorouracil failed to increase the patency rates in ELDCR.     

Pain treatment and recovery after endoscopic sinus surgery

OBJECTIVES/HYPOTHESIS: Early recovery and pain management after endoscopic sinus surgery (ESS) are largely unexplored regardless of the large number of ESSs performed by otorhinolaryngologists. In the present study, we evaluated whether scheduled administration of acetaminophen (paracetamol) for pain management after ESS would allow faster recovery to normal daily activities compared with acetaminophen administered on an as needed basis. STUDY DESIGN: Open, prospective, randomized, controlled clinical trial with two parallel groups. METHODS: There were 78 patients who were undergoing ESS and were randomized into two groups. The "scheduled" group (n = 38) was instructed to take two acetaminophen 665 mg modified-release tablets three times a day during the first five postoperative days, whereas the "as needed" group (n = 40) was given instructions to use acetaminophen 665 mg tablets only on an as needed basis. Patients filled in a questionnaire at the follow-up visits on the 7th and 30th postoperative days. The main outcome measures were return to normal daily activities (primary endpoint) and pain during the first week after surgery and patients' satisfaction with pain management (secondary endpoints). RESULTS: Patients returned to their normal daily activities in 8.8 (SD 4.8) days in the "scheduled" group versus in 10.3 (SD 7.0) days in the "as needed" group (mean difference 1.5; 95% CI of the difference -1.3 to 4.2; P = .29). In the "scheduled" group, the mean of worst pain was 3.4 (2.9) compared with 5.2 (3.0) in the "as needed" group on an 11-point scale (mean difference 1.7; 95% CI of the difference 0.4-5.2; P = .019). The patients in both groups were equally satisfied with pain management. CONCLUSIONS: The present study suggests that patients recover in 9 to 10 days after ESS when provided with appropriate pain management. Our data indicate that by prescribing scheduled acetaminophen, postoperative pain after ESS can be controlled effectively without the need for opioid analgesics.     

Conscious sedation: a new approach for peritonsillar abscess drainage in the pediatric population.

OBJECTIVE: To assess the safety and efficacy of conscious sedation (CS) in children undergoing emergency department incision and drainage (I&D) of peritonsillar abscesses (PTAs). DESIGN: A 33-month retrospective chart review of all children presenting to the emergency department with the diagnosis of a PTA or peritonsillar cellulitis. Children who underwent CS prior to I&D were compared with children without CS for complications and efficacy. SETTING: St Louis Children's Hospital, an academic tertiary care pediatric hospital. PATIENTS: Fifty-two children were enrolled; 30 PTAs were drained with CS in 27 children (3 underwent I&D twice), and 25 PTAs were drained in 25 children without CS. INTERVENTIONS: The CS team included an otolaryngologist, a pediatric emergency department physician, and a registered nurse. A standardized CS protocol assessing vital signs and level of consciousness was employed during each procedure. A combination of midazolam, ketamine hydrochloride, and glycopyrrolate was used in appropriately weighted calculated doses. Patients were assessed for major and minor airway complications. MAIN OUTCOME MEASURES: Airway complications related to CS were reviewed. Patients who underwent I&D with and without CS were compared with regard to purulent drainage. RESULTS: There were no major airway complications in patients undergoing I&D with CS. There was 1 minor complication in this group, oxygen desaturation to 88%, which resolved with stimulation. Of the 55 procedures, 45 (82%) yielded purulence: 29 (97%) of 30 in the CS group and 16 (64%) of 25 in the non-CS group (chi2 = 9.8; P = .002). Of those children undergoing CS, 3 (10%) of 30 were admitted to the hospital from the emergency department as compared with 6 (24%) of 25 without CS (chi2 = 1.95; P = .16). In the CS group, PTAs had a low recurrence rate of 1 (3.3%) of 30 compared with 2 (8%) of 25 in the non-CS group (chi2 = 0.57; P = .45). No one in the CS group required a secondary procedure under general anesthesia. CONCLUSIONS: This preliminary study demonstrates CS to be a potentially safe and efficacious approach to drainage of PTAs in children. Given its efficacy and its associated lower levels of anxiety and pain for the patient, CS seems to be a promising new approach to caring for children with PTAs.     

Ultrasound-guided fine needle aspiration biopsy of thyroid nodules performed in the office

INTRODUCTION: The majority of thyroid fine needle aspiration biopsies (FNAB) today are performed in the office freehand by palpation. Not infrequently, patients are sent to radiology for an ultrasound-guided FNAB (USG-FNB). Real-time ultrasound (US) allows for continuous visualization of the needle during insertion and sampling. Historically, USG-FNAB has been a procedure performed by a radiologist in a designated radiology suite. In more recent years, with the development of smaller more portable US machines, there has been a push for clinicians other than radiologists to perform the procedure. OBJECTIVE: To evaluate the accuracy and specimen adequacy of thyroid FNAB performed in the office under US guidance by one senior otolaryngologist. METHODS: Retrospective chart review of 203 patients who underwent ultrasound-guided USG-FNA of the thyroid gland between September, 2005, to February, 2007, in the office setting by one senior otolaryngologist. Specimens were reviewed onsite at the time of biopsy for cellular adequacy by a cytotechnologist. RESULTS: A total of 203 patients, 176 females and 27 males, underwent USG-FNA of the thyroid gland. The average age of the females was 52 years, and 59.4 years for the males. A total of 271 FNA biopsies were performed. Two hundred and twenty FNAB were satisfactory specimens (81.2%), 26 were unsatisfactory (9.6%), and 25 (9.2%) were limited due to blood clotting or hypocellularity. Of the FNA specimens that had enough cells to evaluate, 159 were benign, 48 were indeterminate for malignacy, and 13 were positive for malignancy. Of the nodules biopsied, 143 were greater than 1.5 cm (average 2.59 cm, unsatisfactory rate 12.6%), and 128 were less than 1.5 cm (average 1.21 cm, unsatisfactory rate 6.3%).In 44 patients, one or more nodule was biopsied at the same office visit. DISCUSSION: Thyroid US is an indispensable tool in the workup and diagnosis of thyroid disease. It may be used to help identify pathology and physical features suspicious for malignancy and guide FNAB of suspicious nodules. The availability of an office US machine allows the referring physician to perform a service that is normally done in a different department. This ultimately frees up time for both the patient and physician and reduces health care costs by eliminating extra office visits. More importantly, it allows the primary physician to be more knowledgeable and hands on with the patient's overall care. CONCLUSION: This study shows that a trained physician may perform a USG-FNA of the thyroid gland in the office with results comparable to that in the radiology literature.     

Pacific Northwest survey: posttympanostomy tube water precautions

OBJECTIVES: To determine what recommendations are given to patients or parents of patients with tympanostomy tubes regarding water exposure and to elucidate any recommendation differences between primary care and specialty care physicians. DESIGN: Clinical survey. SETTING: General community in the Pacific Northwest, including Washington, Oregon, and Idaho. PARTICIPANTS: Physician surveys (N = 1116) were mailed to otolaryngologists, pediatricians, and family practitioners in the Pacific Northwest. Questions included what, if any, water precautions are given to patients or parents of patients who underwent tympanostomy tube insertion. Data were tabulated and compared among the 3 physician groups. MAIN OUTCOME MEASURES: Recommendations regarding water exposure. RESULTS: A response rate of 23.5% (n = 263) was obtained. Most respondents were self-described otolaryngologists (n = 150) followed by family practitioners (n = 77) and pediatricians (n = 36). chi(2) Analysis of the responses from each specialty group showed an overall significant difference about swimming precautions (P < .001). Further analysis of these data shows that many otolaryngologists (47% [n = 71]) and most primary care physicians (73% [n = 83]) recommend the use of barrier devices for swimming. Another 47% of otolaryngologist respondents allow swimming without any water precautions. With regard to depth of dive, there was no statistical significance found between the physician groups. CONCLUSIONS: Recommendations for swimming precautions are not universal among the physician groups that routinely see patients with tympanostomy tubes. Most primary care physicians and many otolaryngologists continue to prescribe water precautions to patients or parents of patients with tympanostomy tubes, despite published articles that have shown no reduction in the incidence of otorrhea from the use of barrier devices or from the avoidance of swimming.     

Office-based insertion of pressure equalization tubes: the role of laser-assisted tympanic membrane fenestration

OBJECTIVE: To describe the role of the hand-held otoscope combined with a flashscanner CO2 laser, OtoLAM (ESC/Sharplan, Yokneam, Israel), for pressure equalization tube (PET) insertion in an office setting. STUDY DESIGN: Prospective, multisite, clinical cohort trial (Institutional Review Board approved; informed consent) in the setting of pediatric otolaryngology outpatient departments at four tertiary care children's hospitals. METHODS: Selected for the study were 54 patients (96 ears), ages 6 months to 23 years, who met standard indications for PET insertion using cold-knife myringotomy and tube insertion under general anesthesia. PETs were indicated for recurrent otitis media, chronic otitis media with effusion, and eustachian tube dysfunction-all unresponsive to medical therapy. Topical anesthesia was achieved with iontophoresis (n = 1) or topical anesthesia: 8% tetracaine on an Otowick (Xomed Surgical Products, Jacksonville, FL, catalogue No. 400141) against the tympanic membrane for 45 to 180 minutes (n = 53). Laser-assisted tympanic membrane fenestration was performed with the OtoLAM set at single pulse, 2.0- to 2.6-mm spot size, and between 3 and 18 W. Insertion of grommets was accomplished using the otomicroscope and an "alligator" microforceps. Restraints with papoose were used in 79% of children with a mean age of 34.4 months (SD = 60.9 mo). Clinical, parent/patient, and physician satisfaction and comparative cost impact outcomes are described. RESULTS: All ears but three (3%) underwent successful placement of a PET. Pain was described as "absent" in 39%, "present but tolerable" in 30%, and "severe" in 30% of children at the time of procedure; 5 minutes after the procedure pain was described as "absent" in 75%, "present but tolerable" in 22%, and "severe" in 3%. Tube plugging (3 of 74 available ears; 4%) or persistent otorrhea (1 of 74 ears; 1.4%) occurred infrequently at the 1-month follow-up. Before PET insertion, hearing loss was noted in 66% of cases (mild, 38%; moderate, 22%; and severe, 6%). Mild hearing loss was noted in only 8% and moderate hearing loss in 2% of 47 (50%) of the ears at the 3-month follow-up. Ninety-two percent of parents were highly satisfied with the procedure in preference to PETs in the operating room under general anesthesia, and 97% preferred OtoLAM with PET insertion, rather than further courses of antibiotics; only one parent would rather have had the PET insertion under general anesthesia. Cost savings to health care organizations, particularly payers, and to parents are substantial (32%-48%) and warrant attention. Cost to the physician is manageable only if an appropriate approach to the third party payers results in a substantial increase in reimbursements. CONCLUSIONS: The data indicate excellent clinical effectiveness, reduced risk, and high parent and physician satisfaction. Strong incentives for physicians to use this technique are in all stakeholders' best interests. These incentives need to evolve as soon as possible for the more widespread acceptance of OtoLAM with PET insertion in an office setting for appropriately selected patients.     

Cranioplasty in acoustic neuroma surgery

OBJECTIVES: To measure the incidence of postoperative headaches after retrosigmoid resections of acoustic neuromas and to evaluate the impact of cranioplasty on the prevention and management of these headaches. STUDY DESIGN: A prospective evaluation was performed on 30 consecutive patients who underwent a cranioplasty after retrosigmoid excision of their acoustic neuroma. The results were compared with 30 historical control patients who underwent the same procedure but did not have reconstruction with a cranioplasty. The patients were evaluated by review of office records and via telephone questionnaire. METHODS: One group of patients (30 patients) had no cranioplasty, and the other group of 30 patients had primary reconstruction with a titanium mesh-acrylic cranioplasty. All 60 patients were asked to report on the duration and severity of their headaches by means of a standard questionnaire, grading their symptoms on a scale of 1 to 4. The data were subjected to chi2 and Student t test statistical analyses. RESULTS: New-onset, postoperative headaches occurred in 27% of patients, 23% in the cranioplasty group compared with 30% in the group without cranioplasty (a difference that was not statistically significant [P = .158]). However, there was a statistically significant difference in the severity of the headaches (P<.03). The headaches in the cranioplasty group were less severe and were not disabling. There were no complications, infections, or extrusions related to the cranioplasty. CONCLUSIONS: Cranioplasty has not been able to eliminate postoperative headaches. However, the use of cranioplasty has significantly decreased the severity of postoperative headaches after retrosigmoid excision of acoustic neuromas.     

Association of anxiety and depression with reported disease severity in patients undergoing evaluation for chronic rhinosinusitis

OBJECTIVES: We sought to determine the impact of psychiatric comorbidity on symptom density and resource utilization in chronic rhinosinusitis (CRS). METHODS: A prospective cohort of patients who sought evaluation of CRS was studied with the Rhinosinusitis Symptom Inventory and the Hospital Anxiety and Depression Scale. Data concerning symptom scores, symptom domains, and psychiatric comorbidity were analyzed to determine the interactions among psychiatric comorbidity, symptom reporting, and resource utilization in CRS. RESULTS: We studied 143 patients (mean age, 43.4 years). Low, moderate, and high levels of anxiety were reported by 48.3%, 25.9%, and 25.9% of patients, respectively. Low, moderate, and high levels of depression were reported by 76.2%, 9.1%, and 14.7%. For the combined psychopathology group, 43.3%, 25.9%, and 30% had low, moderate, and high levels. Patients with high anxiety levels reported significant elevations of oropharyngeal symptoms (p = .013) and total symptoms (p = .030) in comparison with the low group. Patients with high depression levels reported higher oropharyngeal (p = .003), systemic (p = .001), and total symptom (p = .003) scores than did the low group. High combined psychopathology scores were associated with elevated facial, oropharyngeal, and systemic scores (p < .05). Regarding medical utilization, high anxiety levels or high combined psychopathology scores were associated with more frequent physician visits (p < .05). A high level of depression was associated with increased antibiotic use, missed workdays, and physician visits (p < .05). CONCLUSIONS: High levels of anxiety and depression are common in patients who undergo evaluation for CRS. Psychiatric comorbidity is associated with increased symptoms in CRS and increased health-care utilization. Anxiety and depression should be identified in these patients to structure appropriate treatment.     

Cellular telephone use and risk of intratemporal facial nerve tumor

OBJECTIVES/HYPOTHESIS: Microwave radiation exposure from cellular telephone use has been implicated in the development of intracranial tumors. The intratemporal facial nerve (IFN) is exposed to higher levels of cellular telephone radiation than intracranial tissues. The purpose of the study was to determine whether cellular telephone use is associated with an increased risk of IFN tumors. STUDY DESIGN: Case-control using a structured telephone survey at an academic, tertiary-care referral center. METHODS: Patients with IFN tumors (n = 18) were case-matched with patients treated for acoustic neuroma (n = 51), rhinosinusitis (n = 72), and dysphonia or gastroesophageal reflux disease (n = 69). Risk of facial nerve tumorigenesis was compared by extent of cellular telephone use and other risk factors. RESULTS: The odds ratio of developing an IFN tumor was 0.6 (95% CI, 0.2-1.9) with any handheld cellular telephone use and 0.4 (95% CI, 0.1-2.1) with regular cellular telephone use. No factors were associated with an increased risk for IFN tumor development. CONCLUSIONS: Regular cellular telephone use does not appear to be associated with a higher risk of IFN tumor development. The short duration of widespread cellular telephone use precludes definite exclusion as a risk for IFN tumor development.     

Treatment of benign positional vertigo using the semont maneuver: efficacy in patients presenting without nystagmus

OBJECTIVE: To evaluate and compare the efficacy of the Semont liberatory maneuver on "objective" benign paroxysmal positional vertigo (BPPV) defined as vertigo with geotropic nystagmus in Dix-Hallpike positioning versus "subjective" BPPV defined as vertigo without nystagmus in Dix-Hallpike positioning. STUDY DESIGN: Retrospective chart review. METHODS: One hundred sixty-two patients with positional vertigo during Dix- Hallpike positioning were identified. Patients were evaluated for the presence or absence of nystagmus. All patients underwent the Semont liberatory maneuver. The patient's condition at follow-up was documented at 3 weeks as complete, partial, or failure. Repeated procedures were performed if necessary. RESULTS: There were 127 cases of objective BPPV and 35 cases of subjective BPPV. Overall, 90% of all patients tested had significant improvement of their vertigo after 1.49 maneuvers on average. Improvement was seen in 91% of patients with objective BPPV after 1.59 maneuvers on average, compared with 86% in subjective BPPV after 1.13 maneuvers on average (chi2 test, not significant [P = .5]). Patients with a history of traumatic origin or cause had an overall success rate of 81% compared with 92% for nontraumatic causes or origins (chi2 test, not significant [P = .1]). Recurrences were seen in 29% of patients after a successful initial maneuver; however, 96% of these patients responded to further maneuvers. Four patients with persistent symptoms after conservative management underwent posterior semicircular canal occlusion with resolution of symptoms. CONCLUSION: The Semont liberatory maneuver provides relief of vertigo in patients with positional vertigo, even in patients without objective nystagmus.     

Strategies to prevent recurrence of benign paroxysmal positional vertigo

OBJECTIVE: To determine if a daily routine of Brandt-Daroff exercises increases the time to recurrence and reduces the rate of recurrence of benign paroxysmal positional vertigo (BPPV). DESIGN: Random sample of convenience and retrospective case review. SETTING: Tertiary referral center and outpatient clinic. PATIENTS: One hundred sixteen patients diagnosed with BPPV involving the posterior semicircular canal (BPPV-PC) who were successfully treated with the canalith repositioning procedure. INTERVENTIONS: Patients in the treatment group (n = 43) performed daily Brandt-Daroff exercises, while patients in the no-treatment group (n = 73) performed no exercises. MAIN OUTCOME MEASURES: Follow-up was as long as 2 years. Every 2 months patients were mailed a questionnaire. If BPPV had recurred, patients contacted the principal investigator within 24 hours. Within 1 to 2 weeks, patients were evaluated in the clinic with the Dix-Hallpike maneuver or, if unable to travel to the clinic, interviewed by telephone. RESULTS: Symptoms recurred in 50 (43%) of the 116 subjects, 34 (47%) of 73 in the no-treatment group and 16 (37%) of 43 in the treatment group. There was no significant difference in the frequency of recurrence (Pearson chi(2), P = .33) or time to recurrence (survival analysis, log-rank test, P = .92). A history of recurrent BPPV-PC did not affect frequency of recurrence (Pearson chi(2), P = .33) or time to recurrence (survival analysis, log-rank test, P = .72). CONCLUSION: Our results suggest that a daily routine of Brandt-Daroff exercises does not significantly affect the time to recurrence or the rate of recurrence of BPPV-PC.     

Oral care experiences with 181 nasopharyngeal carcinoma patients receiving radiotherapy in a Taiwanese hospital

OBJECTIVE: The aim of this study is to present our experiences of the oral care of a cohort of nasopharyngeal carcinoma (NPC) patients before receiving radiation therapy in our institution. PATIENTS AND METHODS: A total of 181 (141 males and 40 females) pre-radiation therapy NPC patients who underwent regular recall dental examination and treatment according to a standard protocol of our Dental Department were collected. RESULTS: One hundred and twelve (68.71%) did not have disease recurrence and only 12 patients (7.36%) had metastasis. The rate of expire was 14.92%. The average number of carious tooth was 2.45 (range: 0-16) whereas the mean number extracted tooth was 2.65 (range: 0-14). One hundred and sixty-four patients were recorded to have suffered from oral mucositis. About 7% patients had oral mucositis in the 1st week, but about 50% of patients developed oral mucositis from the 2nd week to the 3rd week after the beginning of radiotherapy. One hundred and thirty-three patients had records of oral infection. About 67% of the patients suffered from candidiasis during radiotherapy. Xerostomia was found in almost 80% of patients during radiation therapy. The mean number of carious tooth of the patient population during/after radiation therapy was significantly higher than the patient population before radiation therapy (7.18+/-7.10 vs. 2.45+/-2.85; chi2=46.32, p<0.0001). Eighty-four patients were regularly followed-up and the rate of lost follow-up was about 53.6%. One hundred and eighteen patients had custom-made fluoride trays fabricated. As comparing patients with fluoride trays to those without, the former had a significantly higher rate of dental follow-up compliance (chi2=48.56, p<0.0001). CONCLUSIONS: The data and protocol presented in this study would enhance the care and life quality of the NPC patients. Our study showed that a pre-radiotherapy dental care regimen should be conducted simultaneously with the patient's treatment plan to treat the disease. Fluoride tray fabrication is recommended for dentate NPC patients receiving radiation therapy, as it may enhance compliance with dental follow-up.
