Clinical Otolaryngology : Official... Dec 2009There is no consensus about the value of objective measurements of nasal patency. (Review)
Review
BACKGROUND
There is no consensus about the value of objective measurements of nasal patency.
OBJECTIVE
To assess the correlation between the subjective sense of nasal patency and the outcomes found with rhinomanometry and acoustic rhinometry.
TYPE OF REVIEW
Structured literature search. SEARCH STRATEGY AND EVALUATION METHOD: Review of English-language articles in which correlations were sought between subjective nasal patency symptoms and objective scores as found with rhinomanometry [nasal airway resistance (NAR)] and acoustic rhinometry [minimal cross-sectional area (MCA)]. Correlations were related to unilateral or combined assessment of nasal passages and to symptomatic nasal obstruction or unobstructed nasal breathing.
RESULTS
Sixteen studies with a level of evidence II-a or II-b fit the inclusion criteria and were further analysed. Almost every possible combination of correlations or lack thereof in relation to the variables included was found. However, when obstructive symptoms were present, a correlation between the patency symptoms with nasal airway resistance and minimal cross-sectional area was found more often than in the absence of symptoms. In cases of bilateral assessment a correlation was found almost as often as it was not between patency symptoms and total nasal airway resistance or combined minimal cross-sectional areas, while in the limited amount of studies in which unilateral assessment was done a correlation was found each time between patency symptoms and nasal airway resistance.
CONCLUSIONS
The correlation between the outcomes found with rhinomanometry and acoustic rhinometry and an individual's subjective sensation of nasal patency remains uncertain. Based on this review, it seems that the chance of a correlation is greater when each nasal passage is assessed individually and when obstructive symptoms are present. There still seems to be only a limited argument for the use of rhinomanometry or acoustic rhinometry in routine rhinologic practice or for quantifying surgical results.

Meta-Analysis Review
BACKGROUND
Preoperative radio(chemo)therapy (pR(C)T) significantly reduces the local recurrence risk and is therefore recommended in stage II/III rectal cancer. However, this multimodal treatment approach may be associated with late adverse effects. To determine the impact of pR(C)T on long-term anorectal, sexual, and urinary function, we performed a systematic review and meta-analysis.
METHODS
PubMed, Embase, and the Cochrane Library were systematically searched for studies reporting on long-term functional outcome after rectal cancer resection with pR(C)T. Only studies that reported anorectal, sexual, and/or urinary function after rectal cancer resection in TME-technique with pR(C)T were eligible for inclusion.
RESULTS
Twenty-five studies, including 6,548 patients, were identified. Methodological quality of the eligible studies was low. The majority of studies reported higher rates of anorectal (14/18 studies) and male sexual dysfunction (9/10 studies) after pR(C)T. Few studies examined female sexual dysfunction (n = 4). Meta-analysis revealed that stool incontinence occurred more often in irradiated patients (risk ratio (RR) = 1.67; 95 % confidence interval (CI), 1.36, 2.05; p < 0.0001) and manometric results were significantly worse after pR(C)T (mean resting pressures (weighted mean difference (WMD) = 15.04; 95 % CI, 0.77, 29.31; p = 0.04) and maximum squeeze pressures (WMD = 30.39; 95 % CI, 21.48, 39.3; p < 0.0001)). Meta-analysis of erectile dysfunction revealed no statistical significance (RR = 1.41; 95 % CI, 0.74, 2.72; p = 0.3). Six of eight studies and meta-analysis demonstrated no negative effect of pR(C)T on urinary function (RR = 1.05; 95 % CI, 0.67, 1.65; p = 0.82).
CONCLUSIONS
Although quality of studies on long-term functional outcome is limited, current evidence demonstrates that pR(C)T negatively affects anorectal function after TME.

Meta-Analysis
OBJECTIVE
To describe and systematically review the current evidence on the effects of swallow therapy augmented by biofeedback in adults with dysphagia (PROSPERO 2016:CRD42016052942).
DATA SOURCES
Two independent reviewers conducted searches that included MEDLINE, EMBASE, trial registries, and gray literature up to December 2016.
STUDY SELECTION
Randomized controlled trials (RCTs) and non-RCTs were assessed, including for risk of bias and quality.
DATA EXTRACTION
Data were extracted by 1 reviewer and verified by another on biofeedback type, measures of swallow function, physiology and clinical outcome, and analysed using Cochrane Review Manager (random effects models). Results are expressed as weighted mean difference (WMD) and odds ratio (OR).
DATA SYNTHESIS
Of 675 articles, we included 23 studies (N=448 participants). Three main types of biofeedback were used: accelerometry, surface electromyography (sEMG), and tongue manometry. Exercises included saliva swallows, maneuvers, and strength exercises. Dose varied between 6 and 72 sessions for 20-60 minutes. Five controlled studies (stroke n=95; head and neck cancer n=33; mixed etiology n=10) were included in meta-analyses. Compared to control, biofeedback augmented dysphagia therapy significantly enhanced hyoid displacement (3 studies, WMD=0.22cm; 95% confidence interval [CI] [0.04, 0.40], P=.02) but there was no significant difference in functional oral intake (WMD=1.10; 95% CI [-1.69, 3.89], P=.44) or dependency on tube feeding (OR =3.19; 95% CI [0.16, 62.72], P=.45). Risk of bias was high and there was significant statistical heterogeneity between trials in measures of swallow function and number tube fed (I 70%-94%). Several nonvalidated outcome measures were used. Subgroup analyses were not possible due to a paucity of studies.
CONCLUSIONS
Dysphagia therapy augmented by biofeedback using sEMG and accelerometry enhances hyoid displacement but functional improvements in swallowing are not evident. However, data are extremely limited and further larger well-designed RCTs are warranted.

Review
BACKGROUND
Achalasia is an infrequent primary motility disorder of the esophagus. Because of uncertain etiology, treatment is only palliative and is directed at decreasing lower esophageal sphincter pressure, improving esophageal emptying and relieving the symptoms of achalasia. Current treatment options include pharmacological, endoscopic and surgical. We undertook a systematic literature review of the management strategies currently available for achalasia.
METHOD
A Medline, PubMed and Cochrane database search was conducted using reference manager 11. Original articles and reviews published in the English literature on the management of achalasia were reviewed. Emphasis was placed on articles published in the last ten years on randomized controlled trials comparing the various forms of treatment.
RESULTS
Esophageal manometry is the standard diagnostic evaluation for achalasia. Accurate diagnosis can also be made based on clinical findings and barium esophagogram. Medical treatment with nitrates or calcium channel blockers has variable results in alleviating the symptoms of achalasia but long-term results are disappointing because of tolerance and side effects. Intrasphincteric injection of botulinum toxin, pneumatic dilatation and surgical myotomy are variably effective at controlling the symptoms of achalasia but each modality has specific strength and weaknesses which make their choice suitable in a particular group of patients. While pneumatic dilatation is superior to botulinum toxin injection surgical myotomy provides the best long-term control of symptoms in patients with achalasia.
CONCLUSION
Laparoscopic myotomy should be the initial treatment for most patients with achalasia. Pneumatic dilatation is the most cost-effective alternative but its long-term efficacy is less than that of surgical myotomy. Endoscopic botulinum toxin injection can be considered when other forms of treatment are contraindicated.

Review
OBJECTIVE
Pelvic floor muscle tone, which includes active and passive components, is argued to be increased in many pelvic health conditions, including those involving pain. This study systematically reviewed evidence for increased pelvic floor muscle tone in pelvic health conditions.
DATA SOURCES
Electronic databases (PubMed, CINAHL, and Embase) were searched up to May 31, 2021. The search strategy included variants of pelvic and/or floor, muscle, and tone using keywords and Medical Subject Headings (MeSH) terms.
STUDY ELIGIBILITY CRITERIA
Studies were included if they investigated increased tone of the pelvic floor muscle and reported measures of active or mechanical properties of the pelvic floor muscle in humans with any pelvic health condition, including pain, bowel, urogenital, or sexual dysfunctions. Studies of any design were included, except systematic and narrative reviews. Reference lists of studies, reviews, and book chapters were searched for additional studies.
METHODS
Data were extracted using a standardized form, including measurement tool and outcome measure. Risk of bias was analyzed using a modified ROBINS-I (Risk of Bias In Non-randomized Studies - of Interventions) tool, and a score was allocated to determine whether the study provided "convincing" interpretation (comparison with condition-free control group, valid measure, no application issues).
RESULTS
In total, 151 studies were included, reporting 8 different tools (electromyography, dynamometry, manometry, digital palpation, defecography, ultrasound, magnetic resonance imaging, other). The most common pelvic health condition was pelvic pain (n=16 conditions), followed by bowel and urogenital conditions. Most studies (57%) were cross-sectional. A healthy control group was infrequently included for comparison (27%). Unvalidated methods or methods applied in a manner that precluded convincing interpretation were common (94%). Of the 15 measurement tools that provided convincing evidence, 10 demonstrated greater tone in a pelvic health condition (all pain) compared with controls, and 5 showed no difference.
CONCLUSION
Despite the large literature, few studies provide convincing evidence for increased tone/overactivity of pelvic floor muscles in pelvic health conditions. Interpretation is hampered by design and measurement issues. Terminology was often inaccurate. Few studies investigate male, transgender, and pediatric groups.

World Journal of Gastrointestinal... Aug 2016To evaluate the efficacy and safety of botulinum toxin type A (BTX-A) in the management of patients with anismus.
AIM
To evaluate the efficacy and safety of botulinum toxin type A (BTX-A) in the management of patients with anismus.
METHODS
An organized search of published literature was conducted using electronic databases including: PubMed/MEDLINE, and Cochrane Central Register of Controlled Trials, also an internet-based search using "Google Scholar" service was conducted. Both comparative and observational studies were included. We excluded irrelevant articles, editorials, case reports, reviews, and meta-analyses. The studies that followed the patients less than 6 mo were excluded. Variables collected were demographic data of the patients, technique of BTX-A injection and number of sessions, short-term and long-term clinical improvement, post-injection changes in electromyography (EMG), defecography, manometry, and balloon expulsion test, and complications recorded after BTX-A injection.
RESULTS
Seven studies comprising 189 patients were included in the review. The median age of the patients was 41.2 years and female-to-male ratio was 1.3:1. The median dose of BTX-A injected per procedure was 100 IU (range, 20-100 IU). Lateral injection was done in five trails and combined lateral and posterior injections in two trials. Three studies used endorectal ultrasonography-guided technique, one study used EMG-guided technique, whereas the remaining three studies used manual palpation with the index finger. The median percentage of patients who reported initial improvement of symptoms was 77.4% (range 37.5%-86.7%), this percentage declined to a median of 46% (range 25%-100%) at 4 mo after injection of BTX-A. Rates of improvement evaluated by balloon expulsion test, EMG, and defecography ranged between (37.5%-80%), (54%-86.7%), and (25%-86.6%), respectively. Fourteen (7.4%) patients developed complications after injection of BTX-A. Complication rates across the studies ranged from 0% to 22.6%.
CONCLUSION
Initial satisfactory improvement of symptoms after BTX-A injection remarkably deteriorated after 3 mo of the procedure. However, repeated injection may provide better sustained results with no additional morbidities. Further analysis of more patients is necessary to conclude the safety of BTX-A for the treatment of anismus.

Review
AIM
To assess reference values in the literature for esophageal distensibility and cross-sectional area in healthy and diseased subjects measured by the functional lumen imaging probe (FLIP).
METHODS
Systematic search and review of articles in Medline and Embase pertaining to the use of FLIP in the esophagus was conducted in accordance with the PRISMA guidelines. Cross-sectional area and distensibility at the esophagogastric junction (EGJ) were abstracted for normal subjects, achalasia, and gastroesophageal reflux disease (GERD) patients, stratified by balloon length and volume of inflation.
RESULTS
Six achalasia studies ( = 154), 3 GERD ( = 52), and 5 studies including healthy controls ( = 98) were included in the systematic review. Normative data varied widely amongst studies of healthy volunteers. In contrast, studies in achalasia patients uniformly demonstrated low point estimates in distensibility ≤ 1.6 mm/mmHg prior to treatment that increased to ≥ 3.4 mm/mmHg following treatment at 40mL bag volume. In GERD patients, distensibility fell to the range of untreated achalasia (≤ 2.85 mm/mmHg) following fundoplication.
CONCLUSION
FLIP may be a useful tool in assessment of treatment efficacy in achalasia. The drastic drop in EGJ distensibility after fundoplication suggests that FLIP measurements need to be interpreted in the context of esophageal body motility and highlights the importance of pre-operative screening for dysmotility. Future studies using standardized FLIP protocol and balloon size are needed.

OBJECTIVE
Pediatric inferior turbinate hypertrophy (PedTH) is a frequent and often overlooked cause or associated cause of nasal breathing difficulties. This clinical consensus statement (CCS) aims to provide a diagnosis and management framework covering the lack of specific guidelines for this condition and addressing the existing controversies.
METHODS
A clinical consensus statement (CCS) was developed by a panel of 20 contributors from 7 different European and North American countries using the modified Delphi method. The aim of the CCS was to offer a multidisciplinary reference framework for the management of PedTH on the basis of shared clinical experience and analysis of the strongest evidence currently available.
RESULTS
A systematic literature review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria was performed. From the initial 96 items identified, 7 articles were selected based on higher-evidence items such as randomized-controlled trials, guidelines, and systematic reviews. A 34-statement survey was developed, and after three rounds of voting, 2 items reached strong consensus, 17 reached consensus or near consensus, and 15 had no consensus.
CONCLUSIONS
Until further prospective data are available, our CCS should provide a useful reference for PedTH management. PedTH should be considered a nasal obstructive disease not necessarily related to an adult condition but frequently associated with other nasal or craniofacial disorders. Diagnosis requires clinical examination and endoscopy, whereas rhinomanometry, nasal cytology, and questionnaires have little clinical role. Treatment choice should consider the specific indications and features of the available options, with a preference for less invasive procedures.

Comparative Study Meta-Analysis Review
IMPORTANCE
Efficient diagnosis and early treatment of obstructive sleep apnea may help prevent the development of related morbidity and mortality. Compared with polysomnography (PSG), ambulatory sleep study devices offer the possibility of an accurate diagnosis with convenience and low cost.
OBJECTIVE
To assess the correlation between sleep indexes measured by a portable sleep-testing device (peripheral arterial tonometry [PAT]) and those measured by PSG.
DATA SOURCES
We searched PubMed, MEDLINE, the Cochrane Trial Registry (through May 2013), and relevant article bibliographies.
STUDY SELECTION
Systematic review and meta-analysis of studies assessing correlation of sleep indexes between PAT devices and PSG in adults (aged >18 years). Included studies provided a bivariate correlation coefficient for sleep indexes, specifically the respiratory disturbance index (RDI), apnea-hypopnea index (AHI), and oxygen desaturation index (ODI).
DATA EXTRACTION AND SYNTHESIS
Included studies were reviewed by 2 independent reviewers. Reported correlation values for the RDI, AHI, and ODI between a commercially available PAT device (WatchPAT) and PSG were systematically reviewed. A comprehensive meta-analysis software package was used for statistical analysis.
MAIN OUTCOMES AND MEASURES
Assessment of the correlation between PAT and PSG as measured by AHI, RDI, and ODI.
RESULTS
Fourteen studies met inclusion criteria and had data suitable for pooling (909 patients). Of these, 13 studies had blinded study designs, with PAT and PSG conducted simultaneously in the home or the laboratory setting. One study contained 2 trial phases for the same patient group (n = 29), one laboratory based and the other home based, which were analyzed separately. One study contained 2 different study groups based on age. Overall, correlation of the RDI and AHI was high (r = 0.889 [95% CI, 0.862-0.911]; P < .001). Studies comparing the RDI between PAT and PSG had a combined correlation of 0.879 (95% CI, 0.849-0.904; P < .001); those comparing the AHI, 0.893 (0.857-0.920; P < .001); and those comparing the ODI, 0.942 (0.894-0.969; P < .001). Analysis of publication bias revealed a nonsignificant Egger regression intercept.
CONCLUSIONS AND RELEVANCE
Respiratory indexes calculated using PAT-based portable devices positively correlated with those calculated from the scoring of PSG. Strengthened by the blinded design of most of the included studies, this technology represents a viable alternative to PSG for confirmation of clinically suspected sleep apnea.

Meta-Analysis
OBJECTIVE
To systematically review the literature on use of botulinum toxin to treat pelvic floor tension myalgia and persistent pelvic pain.
DATA SOURCES
The ClinicalTrials.gov , PubMed, EMBASE, and Scopus databases were searched from inception to November 2022 by two independent assessors (B.L.K. and F.G.L.). Identified studies were screened by title and abstract and included after full-text review. Data extraction was subsequently performed and recorded in Microsoft Excel.
METHODS
This study was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines after registration in PROSPERO (CRD42022289132). All randomized studies, prospective studies with more than five participants, and retrospective studies with more than 10 participants published in English or French and assessing the use of botulinum toxin for the treatment of pelvic floor tension myalgia and persistent pelvic pain in women were included. Meta-analyses were performed on randomized data.
TABULATION, INTEGRATION, AND RESULTS
Of 4,722 articles identified, 24 satisfied inclusion criteria. A meta-analysis of five randomized controlled trials totaling 329 participants demonstrated no differences in patient- and clinician-reported outcome measures, including pain, dyspareunia, sexual function, and vaginal manometry. Mean duration of follow-up was 6 months. A qualitative analysis of 14 prospective and four retrospective studies including 804 participants is supportive of botulinum toxin; however, the quality of data is low, and there is marked heterogeneity between studies.
CONCLUSION
Meta-analyses of randomized data do not support the use of botulinum toxin to treat pelvic floor tension myalgia and persistent pelvic pain. Failure of these data to confirm the findings of nonrandomized prospective studies that suggest a treatment benefit may be attributable to the absence of placebo control and confounding outcomes obtained from an active comparator group. Further randomized controlled trials with true placebo are strongly recommended.
