RESUMO
PURPOSE: The primary aim was to compare the prevalence of acute and delayed intracranial haemorrhage (ICH) following mild traumatic brain injury (mTBI) in patients on antithrombotic medication referred to a clinic for oral and plastic maxillofacial surgery. The secondary aim was to evaluate the need for short-term hospitalisation based on initial radiological and clinical findings. METHODS: This was an observational retrospective single-centre study of all patients on antithrombotic medication who were admitted to our department of oral and plastic maxillofacial surgery with mTBI over a 5 year period. Demographic and anamnesis data, injury characteristics, antithrombotic medication, radiological findings, treatment, and outcome were analysed. Patients were divided into the following four groups based on their antithrombotic medication: (1) single antiplatelet users, (2) vitamin K antagonist users, (3) direct oral anticoagulant users, and (4) double antithrombotic users. All patients underwent an emergency cranial CT (CT0) at admission. Based on clinical and radiological evaluation, different treatment protocols were applied. Patients with positive CT0 findings and patients with secondary neurological deterioration received a control CT (CT1) before discharge. Acute and delayed ICH and patient's outcome during hospitalisation were evaluated using descriptive statistical analysis. RESULTS: A total of 696 patients (mean age, 71.6 years) on antithrombotic medication who presented at our department with mTBI were included in the analysis. Most injuries were caused by a ground-level fall (76.9%). Thirty-six patients (5.1%) developed an acute traumatic ICH, and 47 intracerebral lesions were detected by radiology-most of these in patients taking acetylsalicylic acid. No association was detected between ICH and antithrombotic medication (p = 0.4353). In total, 258 (37.1%) patients were admitted for 48 h in-hospital observation. The prevalence of delayed ICH was 0.1%, and the mortality rate was 0.1%. Multivariable analysis identified a Glasgow Coma Scale (GCS) of < 15, loss of consciousness, amnesia, headache, dizziness, and nausea as clinical characteristics significantly associated with an increased risk of acute ICH, whereas age, sex, and trauma mechanism were not associated with ICH prevalence. Of the 39 patients who underwent a control CT1, most had a decreasing or at least constant intracranial lesion; in three patients, intracranial bleeding increased but was not clinically relevant. CONCLUSION: According to our experience, antithrombotic therapy does not increase the rate of ICH after mTBI. A GCS of < 15, loss of consciousness, amnesia, headache, dizziness, and nausea are indicators of higher ICH risk. A second CT scan is more effective in patients with secondary neurological deterioration. Initial CT findings were not clinically relevant and should not indicate in-hospital observation.

PURPOSE: To investigate the effect of intraperitoneal infusion of ropivacaine combined with dexmedetomidine and ropivacaine alone on the quality of postoperative recovery of patients undergoing total laparoscopic hysterectomy (TLH). METHODS: Female patients scheduled to undergo a TLH under general anesthesia at Fujian Maternity and Child Health Hospital were included. Before the end of pneumoperitoneum, patients were laparoscopically administered an intraperitoneal infusion of 0.25% ropivacaine 40 ml (R group) or 0.25% ropivacaine combined with 1 µg/kg dexmedetomidine 40 ml (RD group). The primary outcome was QoR-40, which was assessed before surgery and 24 h after surgery. Secondary outcomes included postoperative NRS scores, postoperative anesthetic dosage, the time to ambulation, urinary catheter removal, and anal exhaust. The incidence of dizziness, nausea, and vomiting was also analyzed. RESULTS: A total of 109 women were recruited. The RD group had higher QoR scores than the R group at 24 h after surgery (p < 0.05). Compared with the R group, NRS scores in the RD group decreased at 2, 6, 12, and 24 h after surgery (all p < 0.05). In the RD group, the time to the first dosage of postoperative opioid was longer and the cumulative and effective times of PCA compression were less than those in the R group (all p < 0.05). Simultaneously, the time to ambulation (p = 0.033), anal exhaust (p = 0.002), and urethral catheter removal (p = 0.018) was shortened in the RD group. The RD group had a lower incidence of dizziness, nausea, and vomiting (p < 0.05). CONCLUSION: Intraperitoneal infusion of ropivacaine combined with dexmedetomidine improved the quality of recovery in patients undergoing TLH. TRIAL REGISTRATION: ChiCTR2000033209, Registration Date: May 24, 2020.

Importance: The dizziness associated with cervical spondylosis is a controversial topic given that many experts believe that cervical spondylosis is a common cause of dizziness, whereas others do not believe it exists. Objective: To compare the risk of dizziness between patients with cervical spondylosis and matched controls (ie, patients with lumbar spondylosis after propensity score matching [PSM]). Design, Setting, and Participants: This cohort study used medical claims data from the National Health Insurance Research Database of Taiwan for patients 60 years or older with cervical or lumbar spondylosis newly diagnosed in any outpatient department between January 1, 2010, and December 31, 2015. Patients diagnosed with cervical spondylosis were included as the study cohort, and those diagnosed with lumbar spondylosis who were matched to the study cohort via PSM were selected as the control cohort. Both cohorts were followed up for 1 year unless they were diagnosed with dizziness, censored by death, or withdrew from the health insurance program. Data analysis was performed from August 9 to September 20, 2022. Main Outcomes and Measures: The main outcome was the date of outpatient diagnosis of dizziness. The risks of dizziness were compared between groups. The relative risk and incidence rate difference were calculated. Results: A total of 3638 patients with cervical spondylosis (mean [SD] age, 67.9 [7.1] years; 2024 [55.6%] male) and 3638 patients with lumbar spondylosis (mean [SD] age, 68.0 [7.1] years; 2024 [55.6%] male) after PSM were selected as the study and control cohorts, respectively. The patients with cervical spondylosis had higher risk of dizziness than matched controls, with a 1-year relative risk of 1.20 (95% CI, 1.03-1.39). The 1-year incidence of dizziness was 10.2% (95% CI, 9.2%-11.2%) in patients with cervical spondylosis and 8.6% (95% CI, 7.7%-9.5%) in the matched group of lumbar spondylosis. The incidence rate difference between the groups was 1.6% (95% CI, 0.3%-3.0%). Conclusions and Relevance: These data support the association between dizziness and cervical spondylosis, but the small difference between groups reveals that dizziness associated with cervical spondylosis is uncommon. Clinicians should be wary of diagnosing a cervical cause for dizziness based on an actual history of cervical spondylosis.

PURPOSE: Meniere's disease (MD) is a disabling condition with symptoms, such as hearing loss, dizziness, and tinnitus. Surgery is the last resort option for managing MD when other treatments are not effective. Surgical labyrinthectomy (SL) is less commonly performed than vestibular neurectomy or chemical labyrinthectomy. We sought to assess the efficacy and safety of the SL procedure. METHODS: A retrospective study was carried out involving a cohort of 25 patients with disabling and drug-resistant MD, who underwent SL performed by the same surgeon at University Hospital UCL Namur between 2009 and 2019. All patients considered their hearing non-functional and requested a radical therapeutic option. We compared subjective and objective measures before and after surgery, retrieved from patient medical records. RESULTS: The difference between the Dizziness Handicap Inventory scores before and after surgery was statistically significant (p < 0.01). 81% of patients being satisfied with surgery. No post-operative complications occurred. Following SL, 14 patients evolved well, both subjectively and clinically, without any further vestibular workup required, which was offered to the other patients. All had a total deafness on the operated side, as expected, while four benefited from multidisciplinary rehabilitation because of persistent tinnitus. The scientific literature on this topic was reviewed, compared, and discussed. CONCLUSIONS: Based on our results, SL represents an efficient and safe approach to achieve vestibular deafferentation in patients with unilateral, disabling, and treatment-resistant MD, with non-functional hearing.

BACKGROUND: Serratus anterior plane block (SAPB) is a promising regional technique for analgesia in thoracic surgery. Till now, several randomized controlled trials (RCTs) have explored the effectiveness of SAPB for postoperative pain control in patients undergoing video-assisted thoracoscopic surgery (VATS), but the sample sizes were small and conclusions remained in controversy. Therefore, we conducted the present systematic review and meta-analysis. METHODS: RCTs evaluating the analgesic performance of SAPB, comparing to control methods (no block, placebo or local infiltration anesthesia), in patients undergoing VATS were searched in PubMed, EMBASE, Web of Science and Cochrane Library from inception to December 31, 2022. Mean difference (MD) and corresponding 95% confidence interval (95%CI) were calculated for postoperative pain scores at various time points, postoperative opioid consumption and length of hospital stay. Pooled relative risk (RR) with 95%CI were calculated for the risk of postoperative nausea and vomiting (PONV) and dizziness. A random-effect model was applied. RESULTS: A total of 12 RCTs (837 participants) were finally included. Compared to control group, SAPB had significant reductions of postoperative pain scores at 2 h (MD = -1.58, 95%CI: -1.86 to -1.31, P < 0.001), 6 h (MD = -2.06, 95%CI: -2.74 to -1.38, P < 0.001), 12 h (MD = -1.72, 95%CI: -2.30 to -1.14, P < 0.001) and 24 h (MD = -1.03, 95%CI: -1.55 to -0.52, P < 0.001), respectively. Moreover, SAPB conferred a fewer postoperative opioid consumption (MD = -7.3 mg of intravenous morphine equivalent, 95%CI: -10.16 to -4.44, P < 0.001) and lower incidence of PONV (RR = 0.56, 95%CI: 0.41 to 0.77, P < 0.001). There was no difference between both groups regarding length of hospital stay and risk of dizziness. CONCLUSION: SAPB shows an excellent performance in postoperative pain management in patients undergoing VATS by reducing pains scores, postoperative opioid consumption and incidence of PONV. However, due to huge heterogeneity, more well-designed, large-scale RCTs are needed to verify these findings in the future.

Myalgic encephalomyelitis or chronic fatigue syndrome (ME/CFS) is a multisystem chronic illness characterized by severe muscle fatigue, pain, dizziness, and brain fog. Many patients with ME/CFS experience orthostatic intolerance (OI), which is characterized by frequent dizziness, light-headedness, and feeling faint while maintaining an upright posture. Despite intense investigation, the molecular mechanism of this debilitating condition is still unknown. OI is often manifested by cardiovascular alterations, such as reduced cerebral blood flow, reduced blood pressure, and diminished heart rate. The bioavailability of tetrahydrobiopterin (BH4), an essential cofactor of endothelial nitric oxide synthase (eNOS) enzyme, is tightly coupled with cardiovascular health and circulation. To explore the role of BH4 in ME/CFS, serum samples of CFS patients (n = 32), CFS patients with OI only (n = 10; CFS + OI), and CFS patients with both OI and small fiber polyneuropathy (n = 12; CFS + OI + SFN) were subjected to BH4 ELISA. Interestingly, our results revealed that the BH4 expression is significantly high in CFS, CFS + OI, and CFS + OI + SFN patients compared to age-/gender-matched controls. Finally, a ROS production assay in cultured microglial cells followed by Pearson correlation statistics indicated that the elevated BH4 in serum samples of CFS + OI patients might be associated with the oxidative stress response. These findings suggest that the regulation of BH4 metabolism could be a promising target for understanding the molecular mechanism of CFS and CFS with OI.

PURPOSE: To determine if Persistent Postural-Perceptual Dizziness (PPPD) is associated with increased burden of dizziness and quality of life. Secondly, if this association is present, to determine if it can be explained by differences in anxiety and/or depression between patients with PPPD and dizzy patients without PPPD. METHODS: Cross-sectional study performed in an outpatient otolaryngology clinic, including patients 18-67 years referred from primary care for suspected vestibular disease with chronic dizziness. Patients underwent clinical examination and completed the following questionnaires: Dizziness Handicap Inventory (DHI), RAND-12 Health Status Inventory and Hospital Anxiety and Depression Scale (HADS). Scores in DHI and RAND-12 were compared between patients diagnosed with PPPD and patients without PPPD. RESULTS: 202 patients were included. 150 (74%) were women and 37 (18%) were diagnosed with PPPD. Patients in the PPPD group had increased burden of dizziness and reduced quality of life (QoL) as shown by a higher mean DHI score (49.2 vs. 30.8; p < 0.001) and reduced mean RAND-12 physical score (39.0 vs. 44.6; p = 0.004). After adjusting for age, gender and HADS, PPPD was associated with a 15.3 (p < 0.001) points increase in DHI score, and a 4.0 (p = 0.020) points decrease in RAND-12 physical score. CONCLUSION: Patients with PPPD have a higher burden of dizziness and a lower physical health-related quality of life (HRQoL) compared to other dizzy patients. The difference was evident also after adjusting for anxiety and depression, illustrating how PPPD is a different entity than these common psychiatric conditions.

OBJECTIVE: To determine the impact of comorbid migraine on quality of life (QOL) in chronic rhinosinusitis (CRS). METHODS: A total of 213 adult patients with CRS were recruited. All participants completed the 22-item Sinonasal Outcome Test (SNOT-22), from which total and validated nasal, ear/facial pain, sleep, and emotional subdomain scores were calculated, and the 5-dimension EuroQol general health questionnaire (EQ-5D), from which the visual analogue scale (VAS) and health utility value (HUV) were calculated. The presence of comorbid migraine was determined by a score of ≥4 on the 5-item Migraine Screen Questionnaire (MS-Q). RESULTS: Of the participants, 36.2% were screened positive for having comorbid migraine. The mean SNOT-22 score was 64.9 (SD: 18.7) in participants with migraine and 41.5 (SD: 21.1) in participants without migraine (p < 0.001). The mean EQ-5D VAS and HUV were 60.2 (SD: 21.9) and 0.69 (SD: 0.18), respectively, in participants with migraine and 71.4 (SD: 19.4) and 0.84 (SD: 0.13), respectively, in participants without migraine (p < 0.001 for both). Higher ear/facial pain (OR = 1.22, 95% CI: 1.10-1.36, p < 0.001) and sleep (OR = 1.11, 95% CI: 1.04-1.18, p = 0.002) SNOT-22 subdomain scores were positively associated with migraine. The SNOT-22 item scores related to dizziness, reduced concentration, and facial pain, in descending order, were most associated with migraine. The presence of nasal polyps (OR = 0.24, 95% CI: 0.07 - 0.80, p = 0.020) was negatively associated with migraine. CONCLUSION: Comorbid migraine may be relatively common amongst CRS patients, and its presence is associated with significantly worse QOL. Dizziness as a symptom in CRS patients may be particularly indicative of migraine. LEVEL OF EVIDENCE: 3 Laryngoscope, 133:3279-3284, 2023.

OBJECTIVES AND METHODS: We report a unique case of Bow Hunter's syndrome with a dominant aberrantly coursing right vertebral artery (VA), presenting with persistent dizziness and syncope despite previous decompressive surgery at vertebral levels C5-C6. RESULTS: Re-evaluation with computed tomography-scan during provocation of dizziness by neck rotation revealed compression of the right VA at level C6 from against the ipsilateral posterior border and superior cornu of the thyroid cartilage. Laryngoplasty resulted in complete resolution of symptoms. CONCLUSION: This extremely rare cause of Bow's Hunter's syndrome should be considered, especially in refractory cases after neurosurgical decompression, and surgical management is straightforward and successful.

PURPOSE: To evaluate the vestibulospinal reflex and vestibulo-ocular reflex (VOR) in patients with chronic suppurative otitis media (CSOM) using posturography and the video head impulse test (vHIT). METHODS: Sixty-five patients with CSOM and 65 healthy participants as controls were included. Patients with CSOM were instructed to complete the dizziness handicap inventory (DHI). All participants underwent otoscopy, pure-tone audiometry, posturography sensory organization test (SOT), and vHIT. RESULTS: Patients with CSOM exhibited a high prevalence of dizziness. The CSOM group had poor SOT vestibular scores compared to the control group. Patients with CSOM had worse sways in the antero-posterior and mediolateral planes. The CSOM group was divided into two subgroups according to the type of hearing loss. SOT vestibular scores were significantly poorer in the mixed hearing loss group than those in the conductive hearing loss group. We found a positive correlation between disease duration and poor SOT vestibular scores. Moreover, poor SOT vestibular scores correlated with high DHI scores. We found abnormalities in the vHIT results in the CSOM group in the form of low VOR gain and corrective saccades. CONCLUSION: Our study provides clinical evidence of dizziness, poor postural control, and VOR abnormalities in patients with CSOM. The presence of sensory elements of hearing loss in patients with CSOM appears to be positively associated with vestibular dysfunction.

PURPOSE: The present study aimed to investigate the clinical features of patients with direction-changing spontaneous nystagmus (DCSN) and gain insight into its underlying mechanisms. METHODS: Medical records and vestibular function test results collected in our dizziness clinic between February 2013 and February 2020 were retrospectively reviewed. Spontaneous nystagmus was recorded while sitting upright using videonystagmography for 2 min to confirm the spontaneous changes in nystagmus direction. Causative disease diagnoses were based on the patients' clinical history, audiometry results, vestibular function tests, and imaging studies. RESULTS: Of 4786 patients, DCSN was observed in 41 (0.86%). Causative disease diagnoses included vestibular neuritis (n = 9), lateral semicircular canal cupulopathy (n = 9), cerebellopontine angle tumor (n = 8), vestibular paroxysmia (n = 2), vestibular migraine (n = 2), vestibular nucleus infarction (n = 1), sudden sensorineural hearing loss with vertigo (n = 2), Meniere's disease (n = 2), Ramsay Hunt syndrome (n = 1), labyrinthine fistula due to middle ear cholesteatoma (n = 1), lateral semicircular canal dysplasia (n = 1), post tympanomastoidectomy dizziness (n = 1), and head trauma (n = 2). CONCLUSIONS: Although the periodicity of DCSN could not be determined because of insufficiently long observation times, it was observed in various central and peripheral vestibulopathies. Careful examination of spontaneous nystagmus over a sufficient period may ensure the detection of DCSN when evaluating dizziness.

Objective:To analyze the clinical characteristics of unilateral acoustic neuromaï¼ANï¼ with normal hearing, so as to provide evidence for early identification AN. Methods:Clinical datas from 73 patients of unilateral AN with normal hearing of Otorhinolaryngology Head and Neck Surgery of Beijing Tiantan Hospital affiliated of Capital Medical University from August 2019 to April 2022 admitted to department were retrospectively analyzed. All patients underwent pure tone audiometryï¼PTAï¼, speech discrimination scoreï¼SDSï¼, auditory brainstem responseï¼ABRï¼, distortion product otoacoustic emissionï¼DPOAEï¼ and head enhanced MRI. Results:The incidence of normal hearing among patients with AN was 10.7%. Maleâ¶female=1â¶2.2; the mean age of the patients wasï¼37.3±9.4ï¼ years; the mean tumor size wasï¼24.2±11.2ï¼ mm. Tinnitus was the most common reason for visit; the patients who had headache and dizziness had larger tumors. Surgery was the main treatment, and the patients who underwent surgery had larger tumors than those of follow-up. Heterogeneous tumors were the most common type of MRI, homogeneous tumors were smaller than heterogeneous and cystic tumors. The sensitivity of ABR in the diagnosis of AN with normal hearing was 95.9%, and that of ≥20 mm tumors was 100%; prolonged â ¤-waves were the most common, patients with â ¤-wave deletion had larger tumors than those with normal or prolonged â ¤-waves. Patients who had the longer the â ¤-wave and the longer difference between â -â ¤ wave had larger tumors. DPOAE was not elicited at full frequency in 11 patients. There was no statistically significant difference in age among patients with different symptoms, treatments, types of MRI, ABR and DPOAE. Conclusion:AN of normal hearing was most common in 30-39 years old women. Patients had different symptoms, phenotypes of MRI and ABR. Patients with normal hearing who had tinnitus, dizziness, headache, facial paraesthesia, and recovery after sudden haring loss can be further examination of ABR and DPOAE for early identification AN. The sensitivity of ABR in diagnosis of hearing normal AN was 95.9%, and the abnormal type of â ¤-wave is related to tumor size.

Pheochromocytomas (PCCs) are rare but potentially lethal tumors that arise from the adrenal medulla. The clinical suspicion and diagnosis of PCC can be challenging due to the non-specific nature of signs and symptoms. In many patients, infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) could lead to long-term symptoms including fatigue, headaches, and cognitive dysfunction. Here, we present the case of a patient incidentally diagnosed with an adrenal mass that proved to be a PCC after imaging was performed due to persisting complaints after coronavirus disease 2019 (COVID-19) infection. A 37-year-old male patient was referred to our center because of a right-sided inhomogeneous adrenal mass, incidentally found during a computed tomographic scan of the thorax performed due to cough and dyspnea that persisted after COVID-19 infection. Other complaints that were present prior to COVID-19 infection included profuse sweating, dizziness, exhaustion with chronic fatigue, and concentration difficulties. The patient had no history of hypertension, his blood pressure was normal, and the 24-h ambulatory blood pressure monitoring confirmed normotension but with the absence of nocturnal dipping. Plasma normetanephrine was 5.7-fold above the upper limit (UL) of reference intervals (738 pg/ml, UL = 129 pg/ml), whereas plasma metanephrine and methoxytyramine were normal at 30 pg/ml (UL = 84 pg/ml) and <4 pg/ml (UL = 16 pg/ml), respectively. Preoperative preparation with phenoxybenzamine was initiated, and a 4-cm tumor was surgically resected. Profuse sweating as well as dizziness was resolved after adrenalectomy pointing toward PCC and not COVID-19-associated patient concerns. Altogether, this case illustrates the difficulties in recognizing the possibility of PCC due to the non-specific nature of signs and symptoms of the tumor, which in this case did not include hypertension and coincided with some of the symptoms of long COVID-19.

OBJECTIVE: Recent evidence has shown that vestibular migraine is strongly associated with cognitive difficulties. However, limited data exist on real-world effects of that dysfunction. The objective of this study is to understand the epidemiology of cognitive dysfunction with vestibular migraine and associated sequelae using National Health Interview Survey data. STUDY DESIGN: Randomized, population-based survey study of US adults. SETTING: We generated a case definition approximating probable vestibular migraine based on Bárány Society criteria and validated that definition in a tertiary care vestibular clinic. PATIENTS: Adult respondents to the 2016 NHIS, which queries a representative sample of the civilian, noninstitutionalized US population. INTERVENTION: Diagnostic. MAIN OUTCOME MEASURES: We evaluated incidence of self-reported cognitive dysfunction with vestibular migraine and whether individuals were more likely to have impaired mobility, falls, and work absenteeism than those without either condition. RESULTS: Among individuals with vestibular migraine, 40% reported "some" and 12% reported "a lot" of difficulty thinking versus 13% and 2% of those without vestibular migraine, respectively. Vestibular migraine sufferers were more likely to have difficulty thinking or remembering compared with respondents without dizziness (odds ratio, 7.43; 95% confidence interval, 6.06-9.10; p < 0.001) when controlled for age, sex, education, stroke, smoking, heart disease, and diabetes. Individuals with both vestibular migraine and cognitive dysfunction had fivefold increased odds of falls and 10-fold increased odds of mobility issues compared with those without either condition. Furthermore, individuals with both vestibular migraine and cognitive dysfunction missed 12.8 more days of work compared to those without either condition. CONCLUSION: Our findings indicate vestibular migraine is not only associated with cognitive dysfunction, but they are together associated with mobility issues, fall risk, and work absenteeism.

Objective: This meta-analysis aims to evaluate the effectiveness and safety of transcutaneous electrical acupoint stimulation (TEAS) in treating post-operative pain. Methods: This meta-analysis was registered in PROSPERO (CRD42021286753). We searched PubMed, Embase, and the Cochrane Library for relevant randomized controlled trials (RCTs) about TEAS in treating postoperative pain that were published before November 2021. The primary outcome was visual analogue scale (VAS) within 24 h after surgery. The secondary outcomes included postoperative opioid analgesic drug consumption and the occurrence of adverse reactions within the postoperative 24-72 h. Adverse reactions included dizziness, nausea, and vomiting. Continuous variables were analyzed using mean difference (MDs) or standardized mean difference (SMDs) and 95% CIs. Relative risk (RR) and 95% CI were used for dichotomous data. The data were pooled and analyzed by RevMan 5.4 and STATA15.0 software. Results: Seventeen trials with 1375 participants were included. The current results suggested that application of TEAS showed obvious superiority in reducing VAS scores (SMD = -1.51, 95% CI = -2.20â¼-0.82, I2 = 96%). Subgroup analysis was performed according to open surgery and minimally invasive surgery. VAS scores were decreased after surgery at 24 h (SMD = -0.84, 95% CI = -1.07â¼-0.6, I2 = 96%; SMD = -0.88, 95% CI = -1.02â¼-0.75, I2 = 96%). The incidence of postoperative dizziness and nausea and vomiting was significantly lower in the TEAS group within postoperative 24-72 h (RR = 0.48, 95% CI = 0.34â¼0.68, I2 = 0%; RR = 0.66, 95% CI = 0.44â¼1.01, I2 = 69%; and RR = 0.49, 95% CI = 0.24â¼1.00, I2 = 51%). Postoperative opioid analgesics were also reduced in the TEAS group within 72 h after surgery (SMD = -2.10, 95% CI = -3.37â¼-0.82, I2 = 96%). Conclusions: TEAS can reduce postoperative pain as well as the incidence of dizziness, nausea, and vomiting and the number of analgesics used after surgery. TEAS is a reasonable modality to incorporate into a multimodal management approach for postoperative pain.

BACKGROUND: In medicine, the symptom of dizziness is one of the most common multidisciplinary causes of emergency medical presentation. Attending physicians are often faced with difficult decisions when evaluating patients with dizziness. A rapid differential diagnostic decision must be made during the initial examination. The goal of this study, was to develop a smartphone-based app that can diagnose and qualify nystagmus. The app should enable differentiation between acute emergencies such as strokes ("central vertigo") and vestibular disorders ("peripheral vertigo") using and recognizing or analyzing the accompanying symptom "nystagmus". MATERIALS AND METHODS: This prospective study was conducted at the Department of Otolaryngology, Head and Neck Surgery "Otto Körner", Rostock (Germany). The experimental study design consisted of two test runs and two control runs. In the two test runs, nystagmus was tracked and evaluated by caloric and optokinetic stimulation, respectively, through a custom-developed app. Sensitivity and correlation were calculated for the app's application performance and compared under different experimental conditions. RESULTS: The patient sample included twenty healthy participants with a mean age of 25.6 years (± 2.2 SD) who participated in the study. The overall sensitivity of detection of nystagmus averaged 82.14% in the optokinetic stimulation test trials. There is no correlation regarding specific subject data and sensitivity. CONCLUSIONS: The results of our experimental validation study show that a smartphone-based nystagmus app is a useful tool for vertigo diagnosis. The results of our analyses show that it is possible to diagnose nystagmus and determine shape or direction with the app.

Importance: Individuals with persistent unilateral vestibular deficits experience loss of quality of life and increased risk of falling, and they have few well-supported options for effective treatment. Objectives: To evaluate whether vestibular retraining using computerized dynamic posturography is associated with reduced participant-reported disability for patients with an objectively assessed unilateral peripheral vestibular deficit and to assess the feasibility of conducting a randomized clinical trial of vestibular retraining using computerized dynamic posturography. Design, Setting, and Participants: This single-group cohort study was conducted from April 29 to July 23, 2021, in a tertiary neurotology clinic among 13 individuals with a stable unilateral vestibular deficit present for more than 6 months, confirmed with videonystagmography and vestibular evoked myogenic potential testing. Statistical analysis was performed from July 7, 2021, to January 25, 2022. Interventions: Twelve twice-weekly sessions of posturography-assisted vestibular retraining with prescribed weight shifting tasks guided by an interactive display. Main Outcomes and Measures: Change in scores on the Dizziness Handicap Inventory (DHI), the Activities-Specific Balance Confidence (ABC) Scale, and the Falls Efficacy Scale-International (FES-I), which participants completed before and after retraining to measure their perception of their disability. They also completed posturography measurements. Secondary outcomes included tolerability of the intervention and rate of completion of the full protocol. Results: A total of 13 participants (8 men [62%]; median age, 51 years [range, 18-67 years]) were enrolled. All 13 participants completed the intervention and all follow-up. After treatment, the median changes in scores were -16 points (95% CI, -20 to 2) for the DHI, -9 (95% CI, -14 to 1) for the FES-I, and 11.9 (95% CI, 0-17.3) for the ABC Scale. Eight participants (62%) improved by greater than the minimum clinically important difference (MCID) for the DHI, whereas 4 (31%) exceeded the MCID for the ABC Scale, and 3 (23%) exceeded the MCID for the FES-I. Participants with moderate to severe disability at baseline (n = 7) had a larger magnitude of improvement in DHI scores than those with mild disability (n = 6) (-18 [95% CI, -78 to 2] vs -1 [95% CI, -8 to 16]). Six of the 7 patients (86%) with moderate to severe disability improved by greater than the MCID for DHI, wherease 4 of 7 patients (57%) improved by greater than the MCID for the ABC Scale, and 3 of 7 patients (43%) improved by greater than the MCID for the FES-I. Conclusions and Relevance: This cohort study suggests that computerized, dynamic posturography-assisted retraining was associated with clinically meaningful improvements in participant-reported disability among those with stable unilateral vestibular deficit and moderate to severe disability. Further studies should compare posturography-assisted vestibular retraining with conventional physical therapy rehabilitation techniques.

BACKGROUND: Perioperative opioid use is associated with postoperative bowel dysfunction, which causes longer hospital stay and higher healthcare costs. This study aimed to investigate the effect of the equivalent doses of fentanyl, oxycodone, and butorphanol on bowel function in patients undergoing laparoscopic hysterectomy. METHODS: In this randomized controlled trial, 135 patients undergoing laparoscopic hysterectomy received postoperative intravenous patient-controlled analgesia (IV-PCA) with fentanyl 8.3 µg/kg, butorphanol 0.16 mg/kg, and oxycodone 0.5 mg/kg (1: 20: 60), respectively. The primary outcome measure was the recovery of bowel function. We also evaluated and recorded the following nine indicators: pain score, sedation level, leukocyte count, percentage of neutrophils, plasma potassium levels, time to first ambulation, postoperative side effects, patients' satisfaction, and postoperative hospital length of stay. RESULTS: The mean time to flatus was significantly prolonged in Group B (45.2 ± 11.6 h) compared with Group F (33.1 ± 11.2 h, P < 0.001) and Group O (36.2 ± 10.9 h, P = 0.001). The incidence of somnolence and dizziness prove higher in Group B (P < 0.001). No statistical difference was observed in the mean time to tolerate oral diet, time to defecation, analgesic outcome, satisfaction score, time to first ambulation, and postoperative hospital length of stay. CONCLUSIONS: Compared with fentanyl and oxycodone, butorphanol prolonged the recovery of bowel function with more severe somnolence and dizziness, suggesting that butorphanol is not well suitable for IV-PCA in patients undergoing laparoscopic hysterectomy.

BACKGROUND: Postoperative orthostatic intolerance can limit mobilization after hip and knee arthroplasty. The literature is lacking on the incidence and risk factors associated with orthostatic intolerance after elective arthroplasty. METHODS: A retrospective case-control study of primary total hip, total knee, and unicompartmental knee arthroplasty patients was conducted. Patients with orthostatic events were identified, and potential demographic and perioperative risk factors were recorded. Orthostatic intolerance was defined as postoperative syncope, lightheadedness, or dizziness, limiting ambulation and/or requiring medical treatment. Statistical analysis was completed using Pearson's chi-square test for categorical data and t-tests for continuous data. Binary logistic regression was performed. RESULTS: A total of 500 consecutive patients were included. The overall incidence of orthostatic intolerance was 18%; 25% in total hip arthroplasty (THA) and 11% in total knee arthroplasty. On univariate analysis, significant risk factors for developing postoperative orthostatic intolerance include older age, female gender, THA surgery, lower American Society of Anesthesiologists class, absence of recreational drug use, lower estimated blood volume, lower preoperative diastolic blood pressure, spinal with monitored anesthesia care (MAC), posterior approach for THA, bupivacaine use in spinal, percent of blood loss, postoperative oxycodone or tramadol use, higher postoperative intravenous fluid volume, and lower postoperative hemoglobin. Multivariate analysis demonstrated persistent significance of female gender, THA surgery, spinal with MAC, bupivacaine use in spinal, and more intravenous fluid administered postoperatively. CONCLUSION: Orthostatic intolerance affects a significant number of arthroplasty patients. Awareness of risk factors and modification of perioperative variables linked to orthostatic intolerance may assist the surgeon in choosing the appropriate surgical setting, educating patients, and improving early postoperative recovery.
