Severe Tinnitus

Many individuals with tinnitus report experiencing hyperacusis (enhanced sensitivity to sounds). However, estimates of the association between hyperacusis and tinnitus is lacking. Here, we investigate this relationship in a Swedish study. A total of 3645 participants (1984 with tinnitus and 1661 without tinnitus) were enrolled via LifeGene, a study from the general Swedish population, aged 18–90 years, and provided information on socio-demographic characteristics, as well as presence of hyperacusis and its severity. Tinnitus presence and severity were self-reported or assessed using the Tinnitus Handicap Inventory (THI). Phenotypes of tinnitus with (n = 1388) or without (n = 1044) hyperacusis were also compared. Of 1661 participants without tinnitus, 1098 (66.1%) were women and 563 were men (33.9%), and the mean (SD) age was 45.1 (12.9). Of 1984 participants with tinnitus, 1034 (52.1%) were women and 950 (47.9%) were men, and the mean (SD) age was 47.7 (14.0) years. Hyperacusis was associated with any tinnitus [Odds ratio (OR) 3.51, 95% confidence interval (CI) 2.99–4.13], self-reported severe tinnitus (OR 7.43, 95% CI 5.06–10.9), and THI ≥ 58 (OR 12.1, 95% CI 7.06–20.6). The association with THI ≥ 58 was greater with increasing severity of hyperacusis, the ORs being 8.15 (95% CI 4.68–14.2) for moderate and 77.4 (95% CI 35.0–171.3) for severe hyperacusis. No difference between sexes was observed in the association between hyperacusis and tinnitus. The occurrence of hyperacusis in severe tinnitus is as high as 80%, showing a very tight relationship. Discriminating the pathophysiological mechanisms between the two conditions in cases of severe tinnitus will be challenging, and optimized study designs are necessary to better understand the mechanisms behind the strong relationship between hyperacusis and tinnitus.

This study, carried out in 13 sheep flocks of central-western Mexico, aimed to identify the prevalence of anti-N. caninum antibodies, to develop a risk analysis of the infection and to estimate the prevalence of parasite DNA in blood. A total of 368 serum and blood samples were subjected to ELISA and PCR tests, respectively, and the association between the prevalence of antibodies and some management factors was estimated. The overall prevalence of anti-N. caninum antibodies was 13.5% [50/368; 95% confidence interval (CI) 10–17], ranging from 2.7 to 90% per flock, and 92% of the farms had seropositive animals. In ewes the prevalence was 14% (48/348, 95% CI 10–17) and in rams 10% (2/20; 95% CI 1– 33). The mean prevalence of Neospora DNA in blood was 27% (99/368, 95% CI 22–31), implying a range between 16 and 82%. In rams, the prevalence was 5% (1/20 95% CI 2–26), while in ewes it was 28% (98/348, 95% CI 23–33). The agreement between the tests was k = 0.19. The presence of other domestic animal species in the farms [odds ratio (OR) 4.4] and the consumption of placental debris, fetuses and stillborn lambs by dogs living in the farms (OR 5.8) were demonstrated to be risk factors.

Abstract Background Tibet, a region where average elevation is above 3500 m and socio-economic development is relatively lower, was not included in National Oral Health Survey over decades. The cross-sectional study aimed to investigate the status of dental caries and associated factors in Tibetan adults. Methods Participants aged 35–44, 55–64 and 65–74 years were selected. Decayed, missing, and filled tooth (DMFT), decayed and filled root (DF-Root) and root canal index (RCI) were used to evaluate dental caries. Questionnaire survey on demographic information, socioeconomic status, dietary habits, and oral health knowledge and behavior was conducted. Mann-Whitney U test, logistic regression were used for the statistical analyses. Results A total of 446 participants were enrolled in the survey. Of these: 222 (49.8%) were females, 224 (50.2%) were males; 149 (33.4%), 151 (33.9%), 146 (32.7%) were aged 35–44, 55–64 and 65–74 years respectively. The mean DMFT (SD) was 7.62 (4.84), 12.46 (8.16), and 21.38 (8.93). The filling rate was very low in all age groups (1.77%, 0.98%, 0.45%). The mean DF-Root (SD) was 0.50 (1.04), 1.04 (2.02), 1.32 (2.14), respectively. Root caries index was 42.27, 44.78 and 57.60%. Older age (65–74 age group) was positively associated with crown caries (odds ratio = 31.20, 95% confidence interval: 10.70–90.96). College degree and above and brushing teeth at least once a day were negatively associated with crown caries (odds ratio = 0.28, 95% confidence interval: 0.09–0.89; odds ratio = 0.39, 95% confidence interval: 0.21–0.72, respectively). Rural area, high income level and brushing teeth at least once a day were negatively and tooth with attachment loss was positively associated with root caries. Conclusions The status of dental caries in the adults in Tibet is severe and the treatment rate is very low. The study suggests a correlation between crown caries and the variables age, level of education and frequency of tooth brushing; correlation between root caries and residence, income level, frequency of tooth brushing and exposed root surfaces. These findings could be as reference to develop community based interventions to reduce the prevalence of caries in Tibet.

Background: Particularly with the current increased vancomycin dosing trends, the true risk of the agent’s nephrotoxicity is not well characterized and remains of concern. Objective: To determine the incidence of vancomycin nephrotoxicity in acutely ill hospitalized children and to secondarily characterize the risk factors for this complication. Methods: A single-center retrospective cohort study conducted at UCSF Benioff Children’s Hospital from June 2012 to June 2015. Inpatients 3 months to <19 years who received intravenous vancomycin for ≥48 hours were included. The primary outcome was incidence of nephrotoxicity, defined as an increase in serum creatinine by ≥50% from baseline. Univariate and multivariate analyses were conducted to identify risk factors for vancomycin nephrotoxicity. Results: A total of 291 patients (272 nonnephrotoxic and 19 nephrotoxic) were included in the analysis. Of the 19 patients, 12 (4.1%) were found to have moderate to severe toxicity. The median duration of therapy was 3 (3-5) and 4 (3-6) days for the group with “no nephrotoxicity” and “nephrotoxicity,” respectively. The mean time for the serum creatinine to return to normal in patients with nephrotoxicity was 5.1 days. In the multivariate analysis, only final trough concentration ≥15mg/dL (odds ratio = 3.49, 95% confidence interval = 1.2-10.1; P = .021) and receipt of piperacillin/tazobactam (odds ratio = 3.14, 95% confidence interval = 1.02-9.6; P = .046) were significantly associated with nephrotoxicity. Conclusion: The rate of moderate to severe vancomycin-associated nephrotoxicity in acutely ill children is relatively uncommon and reversible. Kidney injury is associated with increased vancomycin trough concentrations and concomitant receipt of nephrotoxins, particularly piperacillin/tazobactam.

The authors have earlier reported a 1-year prevalence of 13.2 ± 1.9% for migraine in Sweden. This is a subsequent extensive postal survey of the burden of disease and attitudes among migraineurs in a sample ( n = 423, 23% men and 77% women, aged 18-74 years) randomly recruited from all main regions of the country, representative of adults in the general Swedish population with self-considered migraine. Results are presented only from participants who after analysis of symptoms were found to fulfil the International Headache Society's migraine criteria. In order to assess headache duration open-mindedly, the strict time criterion 4-72 h was deliberately disregarded as an inclusion criterion. Individuals who did not consider themselves to have migraine were excluded. Less than half of the group (45%) had received a diagnosis of migraine from a physician. Accordingly, a large number of individuals that would not have come to attention in a clinic-based study have been included. The mean attack frequency was 1.3 per month, and the number of attacks per year in Swedish adults is approximately 10 million. A minority (27%) of sufferers have a majority (68%) of all attacks. The mean attack duration was 19 h. A considerable number of individuals reported attacks < 4 h (15.8%) or > 72 h (6.4%). Less than half of the individuals recovered completely between the attacks. Despite this, only every fourth (27%) participant was currently consulting a physician (6% regularly; 21% occasionally). Most of the migraineurs reported absence from school or work, a negative influence of migraine on the most important aspects of life, and an interest in testing other treatments for migraine during the last year. Of those ( n = 231) migraineurs who had consulted a physician, about 60% were satisfied with information given or treatment offered. This implies, however, that there is still room for improvement in the management of migraine in Sweden.

Abstract Objectives The aim of the study was to assess the association between blood pressure (BP) values and sodium intake from snacks. Methods The mean weekly consumption of snacks was evaluated in 1500 randomly selected undergraduate aged 16–24 years by a food frequency questionnaire. Participants were divided into quartiles of systolic blood pressure and diastolic blood pressure. The mean weekly exercise level was calculated as the product of duration and frequency of each activity (in hours/week), weighted by an estimate of the metabolic equivalent of the activity (MET) and summed for the activities performed. The whole cohort was divided into tertiles of exercise and the individuals were classified as; sedentary, moderately active and active. The cut of points in the whole cohort were respectively; ≤10, 11–29, ≥30 MET h/week. Exercise levels were therefore expressed as MET h/week. Results The mean age, metabolic equivalent of activity (METs), body mass index (BMI) and mean sodium intake from snacks per day were; 20.10 ± 1.44 years, 25.51 ± 10.03 METs h/week, 24.86 ± 4.80 kg/m2 and 1.5 g/day respectively. Systolic blood pressure (SBP) ranges between 104.43 ± 4.89 mmHg and 137.27 ± 16.71 mmHg while the diastolic blood pressure (DBP) ranges from 71.24 ± 7.83–83.11 ± 12.03 mmHg. The SBP and DBP significantly increased from the lower to the higher tertile of sodium from snacks and with increasing frequency of salty snacks consumption (P &lt; 0.001). In the multiple logistic regression model, being in the highest SBP quartile (≥115 mmHg) was significantly associated with consumption of sodium from snacks (odds ratio (OR) = 1.46; 95% confidence interval (CI) 1.13–1.82; P = 0.001), age, gender and body mass index. Also, being in the highest DBP quartile (≥70 mmHg) was significantly associated with consumption of sodium from snacks (odds ratio (OR) = 2.84; 95% confidence interval (CI) 1.41–5.69; P = 0.003), age, body mass index, but not with gender. Conclusions The study has shown that a strong association exists between sodium intake from snack, daily frequency of consumption of salty snacks and blood pressure. Public education and social marketing are needed to motivate the undergraduate to choose healthier snacks with lower sodium content. Funding Sources The study did not receive any funding from any source.

Purpose: The purpose of this study is to determine whether having an optimistic outlook on life decreases the risk of developing incident stroke. Methods: Participants who developed incident stroke in Americans’ Changing Lives study, and participants who did not develop incident stroke (dependent variable) in were compared for demographics, baseline characteristics, comorbidities, and optimistic outlook on life. Numbers and proportions of respondents in both groups were reported for all categorical variables, while mean and standard deviation were reported for age. All statistically significant variables from the above analyses were entered into a logistic regression analysis to ascertain the association between optimistic outlook on life and stroke. Results: Of the 98,577,928 participants, 73,040,055 did not have stroke at baseline. There were 599,190 who developed incident stroke and 1,104,751 who did not develop incident stroke. The mean age (standard deviation) was lower in those who developed incident stroke compared to those who did not [45.9 (13.8) vs. 46.4 (9.9) p<.0001], and participants with an optimistic outlook on life, were 0.20 times less likely to develop stroke as those who did not have an optimistic outlook on life [OR (Odds ratio) 0.20 95% CI (95% confidence interval) 0.20,0.21], after adjusting for confounders. Conclusions: People who have an optimistic outlook on life are less likely to develop incident stroke. The protective value of optimism lends credence to the value of targeting unconventional risk factors in stroke prevention.

Background Intractable nasal and oropharyngeal hemorrhage may be treated with endovascular embolization, but limited data are available. We sought to evaluate the efficacy, safety, and factors associated with rebleeding. Methods A retrospective analysis of consecutive embolizations for nasal and oropharyngeal hemorrhage over a 10-year period at a single institution was performed. Outcomes included procedural success (defined as cessation of hemorrhage in the immediate postoperative period), rebleeding requiring an additional intervention, and procedural complications. Results A total of 47 embolizations on 39 patients were included. The mean age was 60 years (standard deviation 16.1), 23.1% of patients were women, and 21 (53.8%) patients had a previously diagnosed head/neck malignancy. Bleeding sites were the nose in 20 patients and oropharynx in 21 (two patients presented with both nasal and oral bleeding). Immediate procedural success was achieved in 45 (95.7%) embolizations. Rebleeding requiring an additional intervention occurred after 11 (23.4%) embolizations at a median of one day after the procedure. In the multivariate analysis, preoperative hypotension (odds ratio 4.78, 95% confidence interval 1.04–24.61) and the use of coils (odds ratio 6.09, 95% confidence interval 1.24–46.69) were associated with rebleeding requiring repeat intervention. Complications included two watershed strokes that were anticipated due to occlusion of the internal carotid artery. Conclusions In our experience endovascular embolization was a safe and effective treatment option for stopping oral and nasal hemorrhage. However, rebleeding was present after 23.4% of treatments and was associated with preoperative hypotension and the use of coils. Further study in a large multi-institutional cohort is warranted.

Abstract The purpose of this study was to investigate the factors of clinical outcome of selective retina therapy (SRT) for central serous chorioretinopathy (CSC). This retrospective study included 77 eyes of 77 patients, who were treated with SRT for CSC and observed at least 6 months after the treatment. SRT laser (527 nm, 1.7 µs, 100 Hz) was used for treatment. The mean best-corrected visual acuity (BCVA) (logMAR), central macular thickness (CMT) and central choroidal thickness were changed from baseline to at 6-months follow-up with significant difference. The multivariate analyses found that the rate of change (reduction) in CMT was associated with focal leakage type on fluorescein angiography (FA) (p = 0.03, coefficient 15.26, 95% confidence interval 1.72 – 28.79) and larger baseline CMT (p < 0.01, coefficient -0.13, 95% confidence interval -0.13 – -0.05). Complete resolution of subretinal fluid was associated with nonsmoking history (p = 0.03, odds ratio 0.276, 95% confidence interval 0.086 – 0.887) and focal leakage type on FA (p < 0.01, odds ratio 0.136, 95% confidence interval 0.042 – 0.437). This result may be useful for predicting the therapeutic effectiveness of SRT.

Introduction Open thyroidectomy is the most common approach to thyroid surgery. However, ‘scarless’ (in the neck) endoscopic thyroidectomy, consisting of endoscopic and robotic surgery, is progressively being adopted for its perceived cosmetic benefits. This study aims to determine the patient’s preferred surgical approach and to identify the factors that influence their decision. Materials and methods A pilot study consisting of 100 patients with a surgical thyroid disorder were prospectively recruited from a single tertiary centre. An interviewer-administered survey was conducted. Demographic, socioeconomic status, scar perception and an adapted body image scale were evaluated to identify factors that shaped the patient’s perception of the surgical approach. Results The mean age of participants was 54.5 ± 13.0 years; 72% were women and 87% Chinese. Of the 100 patients, 75 patients considered scarless endoscopic thyroidectomy as their preferred surgical approach while 25 patients opted for open thyroid surgery. Improvement in scar perception score between scarless endoscopic thyroidectomy and open thyroid surgery is associated with an increased willingness to choose scarless endoscopic thyroidectomy. The mean body image scale score was 6.9 ± 2.8, indicating no statistical difference between the surgical approaches. On multivariate analysis, improvement in scar perception score (odds ratio 3.38, 95% confidence interval 1.11–10.29) and having surgeon recommendation (odds ratio 6.38, 95% confidence interval 1.80–22.63) were independently associated with interest in scarless endoscopic thyroidectomy. Conclusion Patients interest in undergoing scarless endoscopic thyroidectomy is driven by improved scar perception and surgeon’s recommendation compared with open thyroid surgery.

Objective This meta-analysis was performed to evaluate the efficacy of sexual intercourse for treatment of distal ureteral stones. Methods Randomized controlled trials (RCTs) of sexual intercourse for treatment of distal ureteral stones were searched using PubMed, EMBASE, and the Cochrane Controlled Trials Register. Results Three RCTs comprising 240 patients were included in the meta-analysis, which showed that sexual intercourse was effective in treating distal ureteral stones. The expulsion rate of distal ureteral stones at the second week (odds ratio [OR] = 6.61, 95% confidence interval [CI]: 3.66 to 11.94), expulsion rate of distal ureteral stones at the fourth week (OR = 4.00, 95% CI: 2.09 to 7.64), and number of analgesic injections (mean difference [MD] = −0.79, 95% CI: −1.51 to −0.08) indicated that sexual intercourse was more effective than placebo. However, the mean expulsion time of distal ureteral stones (MD = −3.98, 95% CI: −8.77 to 0.81) showed no difference between sexual intercourse and placebo. Conclusions Compared with placebo, sexual intercourse exhibited greater efficacy for the treatment of distal ureteral stones, whilst potentially alleviating pain.
