Effects of long-term averaging of quantitative blood pressure traits on the detection of genetic associations.

Blood pressure (BP) is a heritable, quantitative trait with intraindividual variability and susceptibility to measurement error. Genetic studies of BP generally use single-visit measurements and thus cannot remove variability occurring over months or years. We leveraged the idea that averaging BP measured across time would improve phenotypic accuracy and thereby increase statistical power to detect genetic associations. We studied systolic BP (SBP), diastolic BP (DBP), mean arterial pressure (MAP), and pulse pressure (PP) averaged over multiple years in 46,629 individuals of European ancestry. We identified 39 trait-variant associations across 19 independent loci (p < 5 × 10(-8)); five associations (in four loci) uniquely identified by our LTA analyses included those of SBP and MAP at 2p23 (rs1275988, near KCNK3), DBP at 2q11.2 (rs7599598, in FER1L5), and PP at 6p21 (rs10948071, near CRIP3) and 7p13 (rs2949837, near IGFBP3). Replication analyses conducted in cohorts with single-visit BP data showed positive replication of associations and a nominal association (p < 0.05). We estimated a 20% gain in statistical power with long-term average (LTA) as compared to single-visit BP association studies. Using LTA analysis, we identified genetic loci influencing BP. LTA might be one way of increasing the power of genetic associations for continuous traits in extant samples for other phenotypes that are measured serially over time.

Incidence and risk factors for Contegra graft infection following right ventricular outflow tract reconstruction: long-term results.

OBJECTIVES: The aim of this study was to evaluate the risk factors associated with Contegra graft (Medtronic Minneapolis, MN, USA) infection after reconstruction of the right ventricular outflow tract. METHODS: One hundred and six Contegra grafts were implanted between April 1999 and April 2010 for the Ross procedure (n = 46), isolated pulmonary valve replacement (n = 32), tetralogy of Fallot (n = 24), double-outlet right ventricle (n = 7), troncus arteriosus (n = 4), switch operation (n = 1) and redo of pulmonary valve replacement (n = 2). The median age of the patients was 13 years (range 0-54 years). A follow-up was completed in all cases with a median duration of 7.6 years (range 1.7-12.7 years). RESULTS: There were 3 cases of in-hospital mortality. The survival rate during 7 years was 95.7%. Despite the lifelong endocarditis prophylaxis, Contegra graft infection was diagnosed in 12 (11.3%) patients at a median time of 4.4 years (ranging from 0.4 to 8.7 years). Univariate analysis of preoperative, perioperative and postoperative variables was performed and the following risk factors for time to infection were identified: female gender with a hazard ratio (HR) of 0.19 (P = 0.042), systemic-to-pulmonary shunt (HR 6.46, P < 0.01), hypothermia (HR 0.79, P = 0.014), postoperative renal insufficiency (HR 11.97, P = 0.015) and implantation of permanent pacemaker during hospitalization (HR 5.29, P = 0.075). In 2 cases, conservative therapy was successful and, in 10 patients, replacement of the infected valve was performed. The Contegra graft was replaced by a homograft in 2 cases and by a new Contegra graft in 8 cases. Cox's proportional hazard model indicated that time to graft infection was significantly associated with tetralogy of Fallot (HR 0.06, P = 0.01), systemic-to-pulmonary shunt (HR 64.71, P < 0.01) and hypothermia (HR 0.77, P < 0.01). CONCLUSION: Contegra graft infection affected 11.3% of cases in our cohort, and thus may be considered as a frequent entity that can be predicted by both intraoperative and early postoperative factors. After the diagnosis of infection associated with the Contegra graft was confirmed, surgical treatment was the therapy of choice.

Long-term outcomes of pandemic 2009 influenza A(H1N1)-associated severe ARDS.

BACKGROUND: No data on long-term outcomes of survivors of 2009 influenza A(H1N1) (A[H1N1])-associated ARDS are available. The objective of this study was to compare the 1-year outcomes of survivors of A(H1N1)-associated ARDS, according to use or no use of extracorporeal lung assist (ECLA), using its need as an ARDS severity surrogate. METHODS: Survivors of ARDS (12 with ECLA use vs 25 without, corresponding to 75% and 54% of the eligible patients for each group, respectively) selected from the Réseau Européen de Ventilation Artificielle (REVA) registry had previously been healthy, with only pregnancy and/or moderate obesity (BMI ≤ 35 kg/m²) as known risk factors for A(H1N1) infection. Lung function and morphology, health-related quality of life (HRQoL), and psychologic impairment were evaluated. RESULTS: At 1 year post-ICU discharge for the ECLA and no-ECLA groups, respectively, 50% and 40% reported significant exertion dyspnea, 83% and 64% had returned to work, and 75% and 64% had decreased diffusion capacity across the blood-gas barrier, despite their near-normal and similar lung function test results. For both groups, exercise test results showed diminished but comparable exercise capacities, with similar alveolar-arterial oxygen gradients at peak exercise, and CT scans showed minor abnormal findings. HRQoL assessed by the 36-Item Short-Form Health Survey was poorer for both groups than for a sex- and age-matched general population group, but without between-group differences. ECLA and no-ECLA group patients, respectively, had symptoms of anxiety (50% and 56%) and depression (28% and 28%) and were at risk for posttraumatic stress disorder (41% and 44%). CONCLUSIONS: One year post-ICU discharge, a majority of survivors of A(H1N1)-associated ARDS had minor lung disabilities with diminished diffusion capacities across the blood-gas barrier, and most had psychologic impairment and poorer HRQoL than a sex- and age-matched general population group. ECLA and no-ECLA group patients had comparable outcomes. TRIAL REGISTRY: ClinicalTrials.gov; No.: NCT01271842; URL: www.clinicaltrials.gov

The GraftConnector experience. Long-term patency and histological work up in an animal model.

BACKGROUND: A device to perform sutureless end-to-side coronary artery anastomosis has been developed by means of stent technology (GraftConnector). The present study assesses the long-term quality of the GraftConnector anastomosis in a sheep model. METHODS: In 8 adult sheep, 40-55 kg in weight, through left anterior thoracotomy, the right internal mammary artery (RIMA) was prepared and connected to the left anterior descending artery (LAD) by means of GraftConnector, on beating heart, without using any stabilizer. Ticlopidine 250 mg/day for anticoagulation for 4 weeks and Aspirin 100 mg/day for 6 months were given. The animals were sacrificed after 6 months and histological examination of anastomoses was carried out after slicing with the connector in situ for morphological analysis. RESULTS: All animals survived at 6 months. All anastomoses were patent and mean luminal width at histology was 1.8 +/- 0.2 mm; mean myotomia hyperplasia thickness was 0.21 +/- 0.1 mm. CONCLUSIONS: Long-term results demonstrate that OPCABGs performed with GraftConnector had 100% patency rate. The mean anastomotic luminal width corresponds to mean LAD's adult sheep diameter. We may speculate that myotomia hyperplasia occurred as a result of local device oversizing.

Ranibizumab in the management of advanced Coats disease Stages 3B and 4: long-term outcomes.

BACKGROUND: Laser photocoagulation and cryotherapy to completely destroy telangiectatic vessels and ischemic retina in Coats disease is barely applicable in advanced cases with total retinal detachment, and globe survival is notoriously poor in Stages 3B and 4. Anti-vascular endothelial growth factor intravitreal injections may offer new prospects for these patients. METHODS: This study is a retrospective review of all consecutive patients with Coats disease treated with neoadjuvant or adjuvant intravitreal ranibizumab plus conventional and amblyopia treatment as appropriate. RESULTS: Nine patients (median age, 13 months) presenting Coats Stages 3B and 4 (5 and 4 eyes, respectively) were included. Iris neovascularization resolved within 2 weeks and retinal reapplication within 4 months in all patients. At last follow-up, globe survival was 100% with anatomical success in 8 of the 9 eyes. With a median follow-up of 50 months, fibrotic vitreoretinopathy was developed in 5 of the 9 cases, one leading to tractional retinal detachment and ultimately phthisis bulbi. The remaining 4 of the 9 eyes achieved some vision (range, 0.02-0.063). CONCLUSION: To the best of the authors' knowledge, this is the largest reported series of late-stage Coats undergoing anti-vascular endothelial growth factor therapy, a homogenous cohort of patients treated with a single agent and with the longest follow-up. This study supports the role of ranibizumab in advanced disease by transient restoration of the hemato-retinal barrier and suppression of neovascularization to facilitate classic treatment. At the last follow-up, the authors report unprecedented anatomical success and functional outcome.

A non-randomized direct comparison of cognitive-behavioral short- and long-term treatment for binge eating disorder

Background: To compare treatment outcomes of a cognitive-behavioral long-term (CBT-L) and short-term (CBT-S) treatment for binge eating disorder (BED) in a non-randomized comparison and to identify moderators of treatment outcome. Methods: 76 female patients with BED participated in the study: 40 in CBT-L and 36 in CBT-S. Outcome values were compared at the end of the active treatment phase (16 sessions for CBT-L, 8 sessions for CBT-S) and at 12-month follow-up. Results: Both treatments produced significant reductions in binge eating. At the end of active treatment, but not at the end of follow-up, effects of primary outcomes (e.g. remission from binge eating, EDE shape concern) were better for CBT-L than for CBT-S. Dropout rates were significantly higher in CBT-L (35%) than in CBT-S (14%). Moderator analyses revealed that treatment efficacy for rapid responders and individuals exhibiting high scores on the mixed dietary negative affect subtype differed between the CBT-L and CBT-S with respect to objective binges, restraint eating and eating concern. Conclusion: Findings suggest that CBT in general represents an effective treatment for BED, but that subgroups of patients might profit more from a prolonged treatment. Short, lessintensive CBT treatments could nevertheless be a viable option in the treatment of BED.

Severe postoperative complications adversely affect long-term survival after r1 resection for pancreatic head adenocarcinoma.

BACKGROUND: Survival after pancreatic head adenocarcinoma surgery is determined by tumor characteristics, resection margins, and adjuvant chemotherapy. Few studies have analyzed the long-term impact of postoperative morbidity. The aim of the present study was to assess the impact of postoperative complications on long-term survival after pancreaticoduodenectomy for cancer. METHODS: Of 294 consecutive pancreatectomies performed between January 2000 and July 2011, a total of 101 pancreatic head resections for pancreatic ductal adenocarcinoma were retrospectively analyzed. Postoperative complications were classified on a five-grade validated scale and were correlated with long-term survival. Grade IIIb to IVb complications were defined as severe. RESULTS: Postoperative mortality and morbidity were 5 and 57 %, respectively. Severe postoperative complications occurred in 16 patients (16 %). Median overall survival was 1.4 years. Significant prognostic factors of survival were the N-stage of the tumor (median survival 3.4 years for N0 vs. 1.3 years for N1, p = 0.018) and R status of the resection (median survival 1.6 years for R0 vs. 1.2 years for R1, p = 0.038). Median survival after severe postoperative complications was decreased from 1.9 to 1.2 years (p = 0.06). Median survival for N0 or N1 tumor or after R0 resection was not influenced by the occurrence and severity of complications, but patients with a R1 resection and severe complications showed a worsened median survival of 0.6 vs. 2.0 years without severe complications (p = 0.0005). CONCLUSIONS: Postoperative severe morbidity per se had no impact on long-term survival except in patients with R1 tumor resection. These results suggest that severe complications after R1 resection predict poor outcome.

Long-term expansion of transplantable human fetal liver hematopoietic stem cells

Hematopoietic stem cells (HSCs), with their dual ability for self-renewal and multilineage differentiation, constitute an essential component of hematopoietic transplantations. Human fetal liver (FL) represents a promising alternative HSC source, and we previously reported simple culture conditions allowing long-term expansion of FL hematopoietic progenitors. In the present study, we used the nonobese diabetic/severe combined immunodeficiency (NOD/SCID) mouse xenotransplantation assay to confirm that human FL is rich in NOD/SCID-repopulating cells (SRCs) and to show that these culture conditions repeatedly maintained short- and long-term SRCs from various FL samples for at least 28 days. Quantitative limited dilution analysis in NOD/SCID mice demonstrated for the first time that a 10- to over a 100-fold net expansion of FL SRCs could be achieved after 28 days of culture. The efficiency of this culture system may lead to an increase in the use of FL as a source of HSCs for transplantation in adult patients, as previously demonstrated with umbilical cord blood under different culture conditions.

Esotropie précoce: résultats à long terme d'une série de 82 cas opérés par myopexie rétro-équatoriale et recul simultané des deux muscles droits médiaux avant l'âge de 24 mois [Early-onset esotropia operated before the age of 24 months: long-term results of Cüpper's retropexy combined with simultaneous recession of both medial recti]

BACKGROUND: When and how to operate an early-onset esotropia (onset before 6 months of age) is still controversial. We conducted a retrospective study of such patients operated before the age of 24 months. PATIENTS AND METHODS: 82 patients were operated by one surgeon (GK) and followed by the same team. At 5 years post-operation, evaluation criteria included the residual angle of deviation, visual acuity (Birkhäuser Nr 505, 5 m) and binocularity (Lang stereotest I, Bagolini glasses). RESULTS: At 5 years, the residual angle was excellent (0 degrees to + 5 degrees ) in 67 % good, (>+5 degrees to +10 degrees or 0 to -5 degrees ) in 23 %, and poor (>+10 degrees or <-5 degrees ) in 10 %. During the 5 years of follow-up the rate of reoperation was 9.7 %. Isoacuity was obtained in 62 %, slight amblyopia (2 lines of interocular difference) was present in 32 %, and average amblyopia (> 3 lines of interocular difference) was noted in 6 %. Simultaneous perception was present in 53 %, whereas one eye was suppressed or results were undetermined in 47 %. No patient demonstrated stereoscopy using the Lang's stereotest I. CONCLUSION: The results from our study demonstrate that early surgery of early-onset esotropia has a favourable outcome on both visual acuity and the residual angle of strabismus. Simultaneous perception was achieved in 53 %. These figures are comparable to the results of the ELISSS multicentric study.

Long-term treatment of eosinophilic esophagitis esophagitis with budesonide

BACKGROUND: Eosinophilic esophagitis (EoE) is a chronic-inflammatory disease of the esophagus, characterized by esophagus-related symptoms and a dense tissue eosinophilia, both refractory to proton pump inhibitors. Topical corticosteroids have proven effective in inducing clinical and histologic remission. However, a long-term strategy for the management of this chronic disease is not yet defined. METHODS: In a randomized, double-blind, placebocontrolled, long-term trial, we evaluated the efficacy of twice-daily 0.25 mg swallowed budesonide in maintaining a remission in adult EoE with prior response to induction therapy. Pre- and post-treatment disease activity was assessed clinically, endoscopically, histologically, by immunofluorescence and by high-resolution endosonography. The primary end point was the ability to maintain histologic remission (<5 eos/hpf) of EoE in. Secondary end points were the efficacy on symptom control and on tissue remodeling as well as the determination of the safety of long-term esophageal administration of topical corticosteroids. RESULTS: During a 50-week therapy of quiescent EoE with low-dose budesonide the esophageal eosinophil load (ECP staining) increased from 1.1 to 29.9 eos/hpf, but under placebo the increase was significantly larger (0.5 to 51.1 eos/hpf; p=0.01). At the end of the studyperiod, 35.7% (5/14) of the budesonide patients were in complete and 14.3% (2/14) in partial histologic remission; with placebo no patient was in complete and 28.6% (4/14) were in partial remission (p=0.0647). The increase of the symptom score was markedly lower in budesonide- (0.79 to 2.29 points) than in placebo-patients (0.71 to 4.00 points; p=0.0875). The median time to relapse of symptoms was >125 days in the budesonide and 95 days in the placebo group (p = 0.14). Measured by high-resolution endosonography, all EoE patients had pre-treatment a highly thickened esophageal wall compared with healthy controls (3.05±1.08 mm vs. 2.18±0.35 mm; p<0.0001). Long-term topical budesonide reduced mainly the thickness of the superficial wall layers (mucosa, 0.75 mm to 0.45 mm; p=0.025) whereas the response of the deeper layers was less pronounced (submucosa 1.31 to 1.08 mm; p=0.19 and muscularis 0.82 to 0.76 mm; p=0.72). Budesonide did not evoke any mucosal atrophy. CONCLUSIONS: This study clearly demonstrates that 1) Untreated eosinophil inflammation results in an impressive remodeling of the esophagus; 2) A therapy is therefore needed; 3) The high relapse rate after short-term therapy requires a long-term management and 4) Maintenance treatment with budesonide is well tolerated and keeps half of the patients in remission.

Achievement of at least very good partial response is a simple and robust prognostic factor in patients with multiple myeloma treated with high-dose therapy: long-term analysis of the IFM 99-02 and 99-04 Trials.

PURPOSE: The prognostic impact of complete response (CR) achievement in multiple myeloma (MM) has been shown mostly in the context of autologous stem-cell transplantation. Other levels of response have been defined because, even with high-dose therapy, CR is a relatively rare event. The purpose of this study was to analyze the prognostic impact of very good partial response (VGPR) in patients treated with high-dose therapy. PATIENTS AND METHODS: All patients were included in the Intergroupe Francophone du Myelome 99-02 and 99-04 trials and treated with vincristine, doxorubicin, and dexamethasone (VAD) induction therapy followed by double autologous stem-cell transplantation (ASCT). Best post-ASCT response assessment was available for 802 patients. RESULTS: With a median follow-up of 67 months, median event-free survival (EFS) and 5-year EFS were 42 months and 34%, respectively, for 405 patients who achieved at least VGPR after ASCT versus 32 months and 26% in 288 patients who achieved only partial remission (P = .005). Five-year overall survival (OS) was significantly superior in patients achieving at least VGPR (74% v 61% P = .0017). In multivariate analysis, achievement of less than VGPR was an independent factor predicting shorter EFS and OS. Response to VAD had no impact on EFS and OS. The impact of VGPR achievement on EFS and OS was significant in patients with International Staging System stages 2 to 3 and for patients with poor-risk cytogenetics t(4;14) or del(17p). CONCLUSION: In the context of ASCT, achievement of at least VGPR is a simple prognostic factor that has importance in intermediate and high-risk MM and can be informative in more patients than CR.

Long-term outcome of primary endoresection of choroidal melanoma.

BACKGROUND: Endoresection of choroidal melanoma may offer the best hope of conserving vision in some patients but is controversial because of concerns regarding iatrogenic tumour dissemination. METHODS: Retrospective, non-randomised study of consecutive patients who underwent endoresection for choroidal melanoma at the Liverpool Ocular Oncology Centre between 1996 and 2010. RESULTS: The study included 71 patients with a mean age of 58.7 years. The tumour extended within 2 disc diameters of the optic disc in 46 (65%) eyes, involving the disc in 24 (34%) eyes. The mean largest basal tumour diameter and tumour thickness were 9.5 mm and 4.4 mm, respectively. The median follow-up was 4.1 years. The visual acuity at the latest follow-up was better than 6/30 in 31% eyes. The main causes of visual loss were foveal excision, rhegmatogenous retinal detachment (RD) and proliferative vitreo-retinopathy (PVR). Local recurrence developed in two patients (3%), who were treated by enucleation and proton beam radiotherapy, respectively. RD occurred in 16 cases (22%). Three (4%) eyes were enucleated, two because of PVR and one because of local tumour recurrence. Five patients died of metastatic disease. CONCLUSIONS: Endoresection achieved high rates of local tumour control. This operation would seem to be a useful alternative to radiotherapy as a means of conserving vision in eyes with juxtapapillary melanoma.

Higher CNS penetration-effectiveness of long-term combination antiretroviral therapy is associated with better HIV-1 viral suppression in cerebrospinal fluid.

OBJECTIVES: To determine HIV-1 RNA in cerebrospinal fluid (CSF) of successfully treated patients and to evaluate if combination antiretroviral treatments with higher central nervous system penetration-effectiveness (CPE) achieve better CSF viral suppression. METHODS: Viral loads (VLs) and drug concentrations of lopinavir, atazanavir, and efavirenz were measured in plasma and CSF. The CPE was calculated using 2 different methods. RESULTS: The authors analyzed 87 CSF samples of 60 patients. In 4 CSF samples, HIV-1 RNA was detectable with 43-82 copies per milliliter. Median CPE in patients with detectable CSF VL was significantly lower compared with individuals with undetectable VL: CPE of 1.0 (range, 1.0-1.5) versus 2.3 (range, 1.0-3.5) using the method of 2008 (P = 0.011) and CPE of 6 (range, 6-8) versus 8 (range, 5-12) using the method of 2010 (P = 0.022). The extrapolated CSF trough levels for atazanavir (n = 12) were clearly above the 50% inhibitory concentration (IC50) in only 25% of samples; both patients on atazanavir/ritonavir with detectable CSF HIV-1 RNA had trough levels in the range of the presumed IC50. The extrapolated CSF trough level for lopinavir (n = 42) and efavirenz (n = 18) were above the IC50 in 98% and 78%, respectively, of samples, including the patients with detectable CSF HIV-1 RNA. CONCLUSIONS: This study suggests that treatment regimens with high intracerebral efficacy reflected by a high CPE score are essential to achieve CSF HIV-1 RNA suppression. The CPE score including all drug components was a better predictor for treatment failure in the CSF than the sole concentrations of protease inhibitor or nonnucleoside reverse transcriptase inhibitor in plasma or CSF.

Long-term safety and effectiveness of ritonavir, nelfinavir, and lopinavir/ritonavir in antiretroviral-experienced HIV-infected children.

AIM: To evaluate the long-term safety and effectiveness of ritonavir, nelfinavir, and lopinavir/ritonavir in antiretroviral-experienced, initially protease inhibitor (PI)-naive, human immunodeficiency virus (HIV)-1-infected children. METHODS: HIV-1-infected children enrolled in the Swiss Mother and Child HIV Cohort Study were eligible for this observational cohort study if they received at least 1 PI of interest between March 1996 and October 2003: ritonavir, nelfinavir, or lopinavir/ritonavir. Data regarding demographics, clinical disease and antiretroviral treatment history, HIV-1 RNA copies/mL, CD4 T-cell counts [absolute (cells/microL) and percentages (%)], adverse events, clinical laboratory values, reasons for discontinuation of PIs, and concomitant medications were extracted from the database for PI-naive (first-line) and PI-experienced (second- or higher-line) PI use. RESULTS: The total duration of ritonavir, nelfinavir, and lopinavir/ritonavir use for 133 HIV-1-infected children was 163.8, 235.0, and 46.1 patient-years, respectively. In an on-treatment analysis, first-line therapy with any of the PIs significantly reduced HIV-1 concentrations and increased CD4 T-cell counts and percentages from baseline throughout the 288-week study (P <or= 0.05) for ritonavir and nelfinavir and throughout 84 weeks of use for lopinavir/ritonavir, which was introduced into treatment more recently. All PIs investigated were most effective in PI-naive children. Thirteen PI-associated toxicities occurred requiring treatment changes or interruptions (neurologic symptoms, n = 2; pancreatitis, n = 1; allergic reactions, n = 4; visual symptoms, n = 3; and hyperlipidemia, n = 3). CONCLUSIONS: Long-term PI-based therapy seems to be safe and to result in durable virologic and immunologic effectiveness in HIV-1-infected antiretroviral-experienced children.

Long-term voice outcome following partial cricotracheal resection in children for severe subglottic stenosis.

OBJECTIVE: To correlate the postoperative voice outcome to preoperative glottic involvement, following partial cricotracheal resection (PCTR) in children. The glottic involvement was analysed based on the extent of subglottic stenosis (SGS) in the endoscopic image and functional dynamic assessment using flexible endoscopy. METHODS: We conducted an interobserver study in which two ENT surgeons, blinded to one another's interpretation, independently rated the extent of SGS based on the endoscopic image along with the dynamic functional airway assessment, of 108 children who underwent PCTR for grade III or IV stenosis. Based on the observation, the glottic involvement was rated into 4 categories: Evaluation of the voice was based on a parent/patient proxy questionnaire sent in 2008 to assess the current functional status of the patient's voice. RESULTS: Among the 77 patients available for long-term outcome with a minimum 1-year follow-up, 31 patients had isolated SGS free from vocal cords (group A) and 30 had SGS reaching the under surface of vocal cords with partial or no impairment of abduction of vocal cords (group B). Twelve patients belonged to group C with posterior glottic stenosis and/or vocal cord fusion (without cricoarytenoid ankylosis) and 4 patients had transglottic stenosis and or/bilateral cricoarytenoid ankylosis (group D). The long-term voice outcome following PCTR as perceived by the parent or patient was normal in 18% (14 of 77 patients) and the remaining 63 patients demonstrated mild to severe dysphonia. Patients belonging to group A and B exhibited either normal voice or mild dysphonia. Patients in group C demonstrated dysphonia, which was moderate in severity in the majority (83%). All patients in group D with transglottic stenosis and/or CAA showed severe dysphonia. CONCLUSION: Children with associated glottic involvement are at high risk for poor voice outcome following PCTR. The severity of dysphonia was found to be proportional to the preoperative glottic involvement. Preoperative rating of the extent of glottic involvement based on endoscopic image and dynamic assessment was found to be useful in prognosticating the voice outcome.
