Project description:BackgroundDuring dacryocystorhinostomy (DCR), the lacrimal sac wall biopsy is not routinely performed in our hospital, but it is recommended if there is a suspicion of underlying disease other than preoperatively or intraoperatively chronic inflammation.ObjectiveMost of patients with epiphora have different causes of nasolacrimal duct obstruction (NLDO). This study aims to examine how important routine lacrimal sac biopsy is during endoscopic DCR surgery.Patients & methodsThe study included 50 patients with chronic unilateral epiphora. All patients underwent endoscopic DCR with NLD biopsy. Histopathologic analysis was performed for each specimen.ResultsThe findings of NLD biopsy showed chronic inflammation in 33 cases (66%), chronic dacryocystitis in 9 cases (18%), dacryolith with dacryocystitis in one case, granuloma in 4 cases (8%), rhinoscleroma in 2 cases (4%), and one case had a neoplasm. Histopathologic findings were inflammatory cellular infiltrates in 56%, 30% and 14% in mild, moderate and severe chronic inflammatory state (CIS) score, respectively. Fibrosis in 18%, 20% and 62% in mild, moderate and severe CIS score, respectively. Capillary proliferation in 64%, 32% and 4% in mild, moderate and severe CIS score, respectively. Chronic inflammatory signs in 64%, 32% and 4% in mild, moderate and severe CIS score, respectively.ConclusionAlthough neoplasm and granuloma are rare cause of lacrimal sac or duct obstruction requiring DCR, they were detected through nasolacrimal assessment and routine intraoperative lacrimal sac biopsy.

Project description:Osteitis pubis is a common form of athletic pubalgia associated with femoroacetabular impingement. Endoscopic pubic symphysectomy was developed as a less invasive option than open surgical curettage for recalcitrant osteitis pubis. This technical note demonstrates the use of the anterior and suprapubic portals in the supine lithotomy position for endoscopic burr resection of pubic symphyseal fibrocartilage and hyaline endplates. Key steps include use of the suprapubic portal for burr resection of the posteroinferior symphysis and preservation of the posterior and arcuate ligaments. Endoscopic pubic symphysectomy is a minimally invasive bone-conserving surgery that retains stability and may be useful in the treatment of recalcitrant osteitis pubis or osteoarthritis. It nicely complements arthroscopic surgery for femoroacetabular impingement and may find broader application in this group of co-affected athletes.

Project description:IntroductionObstructive sleep apnea (OSA) is a highly prevalent disorder associated with increased cardiovascular risks. We explored the predictive value of OSA screening instruments in cardiac disease patients awaiting cardiac surgery.MethodsIn this prospective cohort, 107 participants awaiting cardiac surgery from Cleveland Clinic and Johns Hopkins underwent polysomnography after completing Epworth Sleepiness Scale (ESS), Sleep Apnea/Sleep Disorder Questionnaire (SA/SDQ), STOP, STOPBAG2 and Berlin questionnaires. Score comparisons between groups based on apnea-hypopnea index (AHI) ≥15 were performed. Logistic regression with receiver operating characteristic (ROC) analysis was used to investigate optimal threshold.ResultsPrevalence of OSA (AHI ≥5) was 71.9% (77/107) and 51 (47.7%) had moderate-to-severe disease (AHI ≥15). Participants were primarily male (57%) and Caucasian (76.6%). Mean age was 67.3 ± 13.3 years and BMI was 26.5 ± 6.6. Of the five screening tools, STOPBAG2 with a cut-point of 0.381 provided 78% sensitivity and 38% specificity (AUC 0.66, 95%CI 0.55-0.77). SA/SDQ yielded a cut-point of 32 for all subjects (AUC: 0.62, 95%CI 0.51-0.73) with sensitivity and specificity of 60% and 62% respectively, while STOP score ≥2 provided sensitivity and specificity of 67% and 52% respectively (AUC: 0.61, 95%CI 0.51-0.72). Among STOP items, "observed apnea" had the strongest correlation with AHI ≥15 (OR 3.67, 95%CI 1.57-8.54, p = 0.003). The ESS and Berlin were not useful in identifying moderate-to-severe OSA.ConclusionCommon screening tools had suboptimal performance in cardiac surgery patients. STOPBAG2 was better at predicting the probability of moderate-to-severe OSA in patients undergoing cardiac surgery compared to ESS, SA/SDQ, STOP and Berlin questionnaires.

Project description:ObjectiveThis study examined biomechanical changes in pelvic floor after urogynecological surgery.MethodsThis multisite clinical study was designed to explore changes in tissue elasticity, pelvic support, and certain functions (contractive strength, muscle relaxation speed, muscle motility) after pelvic organ prolapse (POP) surgery. A biomechanical mapping of the pelvic floor was performed before and 4 to 6 months after the surgery. The biomechanical data for 52 parameters were acquired by vaginal tactile imaging for manually applied deflection pressures to vaginal walls and pelvic muscle contractions. The two-sample t-test (P < 0.05) was used to test the null hypothesis that presurgery data in group 1 (positive parameter change after surgery) and presurgery data in group 2 (negative parameter change after surgery) belonged to the same distribution.ResultsA total of 78 subjects with 255 surgical procedures were analyzed across 5 participating clinical sites. All 52 t-tests for group 1 versus group 2 had P value in the range from 4.0 × 10-10 to 4.3 × 10-2 associating all of the 52 parameter changes after surgery with the presurgical conditions. The P value of before and after surgery correlation ranged from 3.7 × 10-18 to 1.6 × 10-2 for 50 of 52 tests, with Pearson correlation coefficient ranging from -0.79 to -0.27. Thus, vaginal tactile imaging parameters strongly correlated weak pelvic floor presurgery with the positive POP surgery outcome of improved biomechanical properties.ConclusionsPelvic organ prolapse surgery, in general, improves the biomechanical conditions and integrity of the weak pelvic floor. The proposed biomechanical parameters can predict changes resulting from POP surgery.

Project description:PurposeTo explore the value of MRI-based radiomics features in predicting risk in disease progression for nasopharyngeal carcinoma (NPC).Methods199 patients confirmed with NPC were retrospectively included and then divided into training and validation set using a hold-out validation (159: 40). Discriminative radiomic features were selected with a Wilcoxon signed-rank test from tumors and normal masticatory muscles of 37 NPC patients. LASSO Cox regression and Pearson correlation analysis were applied to further confirm the differential expression of the radiomic features in the training set. Using the multiple Cox regression model, we built a radiomic feature-based classifier, Rad-Score. The prognostic and predictive performance of Rad-Score was validated in the validation cohort and illustrated in all included 199 patients.ResultsWe identified 1832 differentially expressed radiomic features between tumors and normal tissue. Rad-Score was built based on one radiomic feature: CET1-w_wavelet.LLH_GLDM_Dependence-Entropy. Rad-Score showed a satisfactory performance to predict disease progression in NPC with an area under the curve (AUC) of 0.604, 0.732, 0.626 in the training, validation, and the combined cohort (all 199 patients included) respectively. Rad-Score improved risk stratification, and disease progression-free survival was significantly different between these groups in every cohort of patients (p = 0.044 or p < 0.01). Combining radiomics and clinical features, higher AUC was achieved of the prediction of 3-year disease progression-free survival (PFS) (AUC, 0.78) and 5-year disease PFS (AUC, 0.73), although there was no statistical difference.ConclusionThe radiomics classifier, Rad-Score, was proven useful for pretreatment prognosis prediction and showed potential in risk stratification for NPC.Supplementary informationThe online version contains supplementary material available at 10.1007/s12672-021-00460-3.

Project description:BackgroundHypoxic-ischemic encephalopathy (HIE) is a severe pathology, and no unique predictive biomarker has been identified. Our aims are to identify associations of perinatal and outcome parameters with morphological anomalies and ADC values from MRI. The secondary aims are to define a predictive ADC threshold value and detect ADC value fluctuations between MRIs acquired within 7 days (MR0) and at 1 year (MR1) of birth in relation to perinatal and outcome parameters.MethodsFifty-one term children affected by moderate HIE treated with hypothermia and undergoing MRI0 and MRI1 were recruited. Brain MRIs were evaluated through the van Rooij score, while ADC maps were co-registered on a standardized cerebral surface, on which 29 ROIs were drawn. Statistical analysis was performed in Matlab, with the statistical significance value at 0.05.ResultsADC0 < ADC1 in the left and right thalami, left and right frontal white matter, right visual cortex, and the left dentate nucleus of children showing abnormal perinatal and neurodevelopmental parameters. At ROC analysis, the best prognostic ADC cut-off value was 1.535 mm2/s × 10-6 (sensitivity 80%, specificity 86%) in the right frontal white matter. ADC1 > ADC0 in the right visual cortex and left dentate nucleus, positively correlated with multiple abnormal perinatal and neurodevelopmental parameters. The van Rooij score was significantly higher in children presenting with sleep disorders.ConclusionsADC values could be used as prognostic biomarkers to predict children's neurodevelopmental outcomes. Further studies are needed to address these crucial topics and validate our results. Early and multidisciplinary perinatal evaluation and the subsequent re-assessment of children are pivotal to identify physical and neuropsychological disorders to guarantee early and tailored therapy.

Project description:We sought to evaluate preoperative and postoperative productivity losses and quality of life (QOL) impairment reported by patients with recurrent acute rhinosinusitis (RARS) as compared to patients with chronic rhinosinusitis without nasal polyposis (CRSsNP).Prospective, multi-institutional, nested case-control.Participants with RARS (n = 20) and CRSsNP (n = 20) undergoing endoscopic sinus surgery (ESS) were enrolled as part of a prospective cohort study. For comparison, participants diagnosed with RARS cases were age/gender-matched to control participants diagnosed with CRSsNP using a 1:1 ratio.RARS and CRSsNP participants were followed for ?14 months postoperatively. Productivity losses were reported as the number of days missed from normal productive activities out of the previous 90 days. RARS participants reported similar baseline productivity losses (12.6 ± 27.1 [standard deviation]) as participants with CRSsNP (11.7 ± 20.9; P = .314). Postoperatively, improvement in productivity losses was similar between RARS participants and CRSsNP controls (-6.7 ± 20.0 vs. -9.8 ± 19.1; P = .253). Preoperative and postoperative disease-specific QOL measures (Sino-Nasal Outcomes Test-22 and Rhinosinusitis Disability Index) were similar between the two groups. RARS participants reported a significant decrease in days of previous antibiotic (P = .009) and nasal decongestant (P = .004) use following ESS, whereas participants with CRSsNP reported a significant decrease in antibiotic (P = .002) and oral corticosteroid use (P = .002).RARS patients report baseline productivity losses and disease-specific QOL impairment to levels that parallel those with CRSsNP. Patients with RARS report improvement in QOL following ESS in all disease-specific QOL measures and in several medication measures. Productivity losses and postoperative improvements are similar between patients with RARS and CRSsNP.3b Laryngoscope, 126:1046-1053, 2016.

Project description:Objectives/hypothesisTo define long-term health-state utility outcomes in patients undergoing endoscopic sinus surgery (ESS) for refractory chronic rhinosinusitis (CRS).Study designProspective, longitudinal, cohort study.MethodsThe short-form (SF)-12 survey was issued to the 168 patients who were enrolled in an initial study evaluating short-term utility outcomes following ESS. SF-12 responses were converted into SF-6D utility scores using the University of Sheffield algorithm. The primary outcome was mean overall long-term utility level following ESS. Secondary outcomes evaluated annual utility level following ESS and utility outcomes for different subgroups of patients with CRS.ResultsA total of 83 patients provided long-term health-state utility outcomes. The mean overall long-term utility level was 0.80 at a mean follow-up of 5.2 years after ESS. Compared to the baseline (0.67) and short-term follow-up (0.75) utility levels in this group, there was a significant improvement at the long-term period (P = .002). A total of 54% (45/83) of patients achieved long-term postoperative utility scores higher than the United States norm of 0.81. There was a significant improvement in utility scores for all subsequent years after ESS compared to preoperative responses (all P < .028). All subgroups of CRS received significant long-term utility improvements (all P < .001), and those undergoing revision ESS demonstrated continued improvement past the short-term postoperative period.ConclusionsThis study has demonstrated that patients with refractory CRS achieve stable mean long-term utility levels following ESS and often return to a health state comparable to US population norms.

Project description:BackgroundFunctional endoscopic sinus surgery (FESS) was historically predicated on targeted widening of narrow anatomic structures that caused postobstructive persistent sinus inflammation. It is now clear that chronic rhinosinusitis (CRS) is a multifactorial disease with subsets of patients which may require a more extensive surgical approach. This study compares quality-of-life (QOL) and disease severity outcomes after FESS based on the extent of surgical intervention.MethodsParticipants with CRS were prospectively enrolled into an ongoing, multi-institutional, observational, cohort study. Surgical extent was determined by physician discretion. Participants undergoing bilateral frontal sinusotomy, ethmoidectomy, maxillary antrostomy, and sphenoidotomy were considered to have undergone "complete" surgery, whereas all other participants were categorized as receiving "targeted" surgery. Improvement was evaluated between surgical subgroups with at least 6-month follow-up using the 22-item Sino-Nasal Outcome Test (SNOT-22) and the Brief Smell Inventory Test (B-SIT).ResultsA total of 311 participants met inclusion criteria with 147 subjects undergoing complete surgery and 164 targeted surgery. A higher prevalence of asthma, acetylsalicylic acid (ASA) sensitivity, nasal polyposis, and a history of prior sinus surgery (p ≤ 0.002) was present in participants undergoing complete surgery. Mean improvement in SNOT-22 (28.1 ± 21.9 vs 21.9 ± 20.6; p = 0.011) and B-SIT (0.8 ± 3.1 vs 0.2 ± 2.4; p = 0.005) was greater in subjects undergoing complete surgery. Regression models demonstrated a 5.9 ± 2.5 greater relative mean improvement on SNOT-22 total scores with complete surgery over targeted approaches (p = 0.016).ConclusionComplete surgery was an independent predictor of greater postoperative SNOT-22 score improvement, yet did not achieve clinical significance. Further study is needed to determine the optimal surgical extent.

Project description:Objectives/hypothesisThe objective of this investigation was to evaluate endoscopic sinus surgery (ESS) outcomes for chronic rhinosinusitis (CRS) between medical centers to determine if differences in quality-of-life outcomes were detectable. In addition, we sought to identify significant, independent cofactors toward the development of an ESS-specific risk-adjustment model so that ESS outcomes may be appropriately compared between institutions and healthcare providers.Study designProspective, multicenter, observational cohort.MethodsStudy participants electing ESS for CRS were enrolled and randomly selected in equal numbers from three academic clinical practices in North America between April 2011 and May 2015. The magnitude of average 6-month postoperative improvement in patient-related outcome measures (PROMs) was compared between enrollment sites using multivariate linear regression modeling.ResultsA total of 228 participants met inclusion criteria and were included for final analyses (n = 76 per site). The prevalence of septal deviation/septoplasty and oral corticosteroid-dependent conditions was significantly different between enrollment sites (P ≤ 0.004). Each enrollment site generated significant within-subject improvement across all PROMs after ESS (P < 0.001); however, average unadjusted magnitudes of improvement were significantly different between sites for the primary outcome measure. After controlling for baseline PROMs, septal deviation, steroid-dependent conditions, and medication use variables, enrollment site was no longer associated with significant outcome differences (P = 0.535).ConclusionComparison of surgeon outcomes of ESS is feasible and must take into account a number of baseline patient characteristics. Further studies will be critical toward developing an ESS-specific risk-adjustment model and enabling a robust comparison of surgeon outcomes.Level of evidence2c. Laryngoscope, 127:14-21, 2017.
