[Evolution of the USP and IPSS score after continuous positive airway pressure sleep apnea therapy at night]

INTRODUCTION

To assess the impact of nocturnal continuous positive airway pressure (CPAP) treatment of obstructive sleep apnea (OSA) on lower urinary tract (LUTS) symptoms.

MATERIALS AND METHODS

A prospective, monocentric study was conducted between June 2018 and August 2019. Patients with moderate to severe OSA with an indication for treatment with nocturnal CPAP in combination with SBAU were included. SBAUs and their impact were evaluated by completing two self-administered questionnaires (Urinary Symptom Profile (USP) and International Prostate Score Symptom (IPSS)) filled out during the night-time ventilatory polygraph or diagnostic polysomnography for OSA and after 4 months of CPAP treatment.

RESULTS

In 79 patients, after four months of CPAP treatment, USP scores for stress urinary incontinence and overactive bladder were significantly improved, respectively 0.65±1.38 vs 1.13±2.10 ; p<0.0001 and 3.24±2.58 vs 5.43±3.66 ; p<0.0001, IPSS and IPSS-Qdv were significantly improved, respectively 5.20±3.78 vs. 7.44±5.05 ; p<0.0001 and 1.93±1.26 vs. 2.27±1.56 ; p=0.002 as well as IPSS score items on pollakiuria, urgency and nocturia.

CONCLUSION

Treatment with CPAP significantly improved SBAU in four months. Testing urology patients for symptoms of OSA in urology patients seeking SBAU would allow referral of patients suspected of OSA to a specialist for diagnosis and management if necessary.

Time intervals to diagnosis and chemotherapy do not influence survival outcome in patients with advanced pancreatic adenocarcinoma

BACKGROUND

The effect of treatment delay on survival in pancreatic ductal adenocarcinoma (PDAC) remains unclear.

AIMS

This study aimed to assess the prognostic impact of time to diagnosis and chemotherapy in advanced PDAC and factors influencing the time intervals.

METHODS

advanced PDAC patients receiving chemotherapy in five centers in the decade 2007-2016 were included. Key time points during care pathway from clinical presentation to beginning of chemotherapy were retrospectively collected. Multivariate Cox proportional hazard model was performed.

RESULTS

A total of 409 patients were included (mean age 66.1 ± 10.3 years; 250 metastatic (61%); 139 received FOLFIRINOX chemotherapy (34%). The median overall survival (OS) was 7.2 months. The median times from first symptoms and from first specialist visit to the beginning of chemotherapy were respectively 100 days and 47 days. None of time intervals was significantly associated with OS. Significant prognostic factors were FOLFIRINOX chemotherapy (HR 0.6 [0.5-0.8]; P < 0.001), metastasis (HR 1.6 [1.3-2.0]; P = 0.001), WHO PS ≥ 2 (HR 1.6 [1.2-2.1]; P < 0.001) and acute pancreatitis as first symptom (HR 2.9 [1.7-4.9]; P < 0.001). Jaundice shortened time to diagnosis (P < 0.001). Acute pancreatitis (P < 0.001) and diabetes (P = 0.01) increased time to treatment.

CONCLUSION

Wait times from clinical presentation to beginning of chemotherapy do not influence survival in advanced PDAC.

Aneurysm Characteristics, Study Population, and Endovascular Techniques for the Treatment of Intracranial Aneurysms in a Large, Prospective, Multicenter Cohort: Results of the Analysis of Recanalization after Endovascular Treatment of Intracranial Aneurysm Study

BACKGROUND AND PURPOSE

The Analysis of Recanalization after Endovascular Treatment of Intracranial Aneurysm (ARETA) prospective study aims to determine factors predicting recurrence after endovascular treatment for intracranial aneurysms. In this publication, we review endovascular techniques and present the study population. Characteristics of treated and untreated unruptured aneurysms were analyzed.

MATERIALS AND METHODS

Sixteen neurointerventional departments prospectively enrolled patients treated for ruptured and unruptured intracranial aneurysms between December 2013 and May 2015. Patient demographics, aneurysm characteristics, and endovascular techniques were recorded.

RESULTS

A total of 1289 patients with 1761 intracranial aneurysms, 835 (47.4%) ruptured, were enrolled. Of these, 1359 intracranial aneurysms were treated by endovascular means. Ruptured intracranial aneurysms were treated by coiling and balloon-assisted coiling in 97.8% of cases. In unruptured intracranial aneurysms, the rates of flow diversion, flow disruption, and stent-assisted coiling were 11.6%, 6.9%, and 7.8%, respectively. Rupture status and aneurysm location, neck diameter, and sac size significantly influenced the chosen technique. Treated unruptured intracranial aneurysms, compared with untreated counterparts, had larger aneurysm sacs (7.6 ± 4.0 versus 3.4 ± 2.0 mm; P < 0.001) and neck dimensions (4.1 ± 2.2 versus 2.4 ± 1.3 mm; P < 0.001) and more frequently an irregular form (84.6% versus 44.4%; P < 0.001). Also, its location influenced whether an unruptured intracranial aneurysm was treated.

CONCLUSIONS

Our study provides an overview of current neurointerventional practice in the ARETA cohort. The technique choice was influenced by aneurysm morphology, location, and rupture status. Flow diversion, flow disruption, and stent-assisted coiling were commonly used in unruptured intracranial aneurysms, while most ruptured intracranial aneurysms were treated with coiling and balloon-assisted coiling.

Transcultural validation of the Oxford Shoulder Score for the French-speaking population

PURPOSE

Patient-reported outcome measures (PROMs) have been gaining in popularity over the last decade. The Oxford Shoulder Score (OSS) is a well-established self-administered questionnaire for shoulder evaluation adapted for the English-speaking population. The aim of the present study was to develop a translation and a transcultural adaptation of the OSS and to assess its validity in native French-speaker patients with shoulder pain.

METHODS

The translation process was carried out following a translation/back-translation methodology by two translators. All patients completed the French OSS, the Subjective Shoulder Value (SSV), and the Constant score. Internal consistency was tested using Cronbach's α coefficient. Validity was assessed by calculating the Pearson correlation coefficient between the OSS and the Constant score and the SSV.

RESULTS

One hundred forty-four patients suffering from degenerative or inflammatory diseases of the shoulder were included in this study. The average time required to complete the French OSS was 2min and 45s. Seventy patients were asked to complete the questionnaire twice (test/retest reliability). Internal consistency was high with Cronbach's α coefficient=0.93. The intraclass correlation coefficient was 0.91 (95% CI: 0.88-0.94) for test/retest reliability. The French OSS score was significantly correlated with the Constant-Murley score (r=0.73 and P<0.0001) and with the SSV (r=0.68 and P<0.0001).

CONCLUSIONS

The present study shows that the French version of the OSS is reliable, valid, and reproducible. The sensitivity to change now needs to be evaluated. This score was adapted to the French-speaking population for the self-assessment of patients with degenerative or inflammatory disorders of the shoulder.

LEVEL OF EVIDENCE

Level 1, Test of previously developed criteria, diagnostic test study.

[Impact of neurological diseases on the prognosis of bullous pemphigoid: A retrospective study of 178 patients]

BACKGROUND

Bullous pemphigoid (BP) mainly affects elderly patients. It is often associated with neurological disorders, which constitute a major risk factor of the disease. The aim of our study was to determine whether neurological disorders, particularly dementia, influence outcome and mortality in BP patients.

PATIENTS AND METHODS

We conducted a retrospective study of all patients with BP seen in our dermatology department consecutively between 1997 and 2011. Clinical, immunological and therapeutic data, number of relapses and survival status were compared according to the presence at diagnosis of neurological disorders, particularly dementia.

RESULTS

Among the 178 patients included, an associated neurological disease was present in 84 (47.2%) and dementia in 43 (24.2%) at the time of diagnosis of BP. Patients with associated dementia were older and had a lower Karnofsky index. Sixty-four patients (37.8%) had had at least one clinical relapse of BP, chiefly within the first 18 months after starting therapy. Coexistent neurological disease was not associated with BP relapse (P=0.55) contrary to an extensive BP phenotype at diagnosis (P=0.008). Coexistent neurological disease and/or dementia were associated with higher mortality (P=0.03 and P<0.001, respectively), but did not modify the type or the total duration of BP treatment.

CONCLUSION

A coexistent neurological disease or dementia at the time of diagnosis of BP significantly increase the risk of mortality and shortens the duration of clinical follow-up of patients with BP, thus limiting the analysis of their influence on the outcome of BP itself.

Work-related respiratory symptoms in Champagne vineyard workers

BACKGROUND

Vineyard workers (VW) are exposed to various respiratory allergens. The aims of the study were to determine the prevalence of work related respiratory symptoms (WRS) in Champagne VW in France and to analyze the relationships between symptoms, occupational exposure and sensitization profile.

METHODS

VW of Reims area were prospectively recruited between 2007 and 2010. Demographic and occupational characteristics were recorded. Respiratory symptoms were scored for each month of the past year. Results of respiratory functional tests and skin prick tests for common respiratory allergens, grape moulds and vine pollen were recorded.

RESULTS

307 subjects were included. The prevalence of WRS was 11%. Compared to subjects with symptoms unrelated to work, subjects with WRS were more frequently sensitized to gramineae (34% vs 18%, p = 0.05), described ocular itching (74% vs 37%, p < 0.001) and seasonal symptoms (88% vs 69%, p = 0.03) mainly during lifting and trellising (57% vs 17%, p < 0.001).

CONCLUSION

WRS are frequent in Champagne WV and are associated with a sensitization to gramineae and with activities performed close to vine in late spring.

Efficacy of a general practitioner training campaign for early detection of melanoma in France

BACKGROUND

To date, no strategy for improving early diagnosis of melanoma has been evaluated on a population basis in France.

OBJECTIVE

To evaluate the efficacy of a general practitioner (GP) awareness and training campaign in a pilot French geographical region (Champagne-Ardenne), including 1.34 million inhabitants, 1241 GPs, 56 dermatologists and a population-based melanoma registry.

METHODS

All GPs received repeated awareness postal mailings in 2008 and 398 (32.1%) attended training sessions organized by 27 dermatologists. The pre- (2005-7) and post-campaign (2009-11) periods were compared for the following: primary endpoint - the world-standardized incidence of very thick melanomas (VTM) (Breslow thickness ≥ 3 mm); secondary endpoints--the mean Breslow thickness; the proportions of VTM and of thin (< 1 mm) melanomas among invasive cases; and the ratio of in situ/all melanoma cases. Similar measures were performed in the control area of Doubs/Belfort territory (655,000 ha), where no similar campaign was carried out.

RESULTS

The incidence of VTM decreased from 1.07 to 0.71 per 100 000 habitants per year (P = 0.01), the mean Breslow thickness from 1.95 to 1.68 mm (P = 0.06) and the proportion of VTM from 19.2% to 12.8% (P = 0.01). The proportion of thin and in situ melanomas increased from 50.9% to 57.4% (P = 0.05) and from 20.1% to 28.2% (P = 0.001), respectively. No significant variation was observed in Doubs/Belfort territory.

CONCLUSION

These results strongly support the efficacy of such a campaign targeting GPs and provide a rationale for a larger public health campaign in France, including training of GPs by dermatologists and encouraging patients to ask their GP for a systematic skin examination.

[Tonometric response to acetazolamide in patients with retinal detachment]

INTRODUCTION

Acetazolamide reduces intraocular pressure and stimulates absorption of subretinal fluid by the retinal pigment epithelium. Recording the intraocular pressure response to systemic acetazolamide might enable an indirect evaluation of retinal pigment epithelial carbonic anhydrase.

METHODS

The intraocular pressure response to a standardized dose of intravenous acetazolamide (5mg/kg) was evaluated in a "case" group of 15 patients undergoing retinal detachment (RD) surgery and in a control group of 15 patients undergoing epiretinal membrane peeling. Intraocular pressure was measured with a handheld Perkins tonometer in a supine position before (t-2 min) and after the intravenous administration of acetazolamide (t+2 min, t+6 min, t+10 min and t+30 min). The mean variation of the intraocular pressure was compared between the two groups in the non-operated eye at each time point.

RESULTS

A significant reduction of the intraocular pressure was observed in both groups at 2, 6 and 10 minutes (P<0.01) after the injection of acetazolamide (5mg/kg). The reduction was significantly lower in the group of patients who underwent retinal detachment surgery when compared with the group of patients in whom epiretinal membrane peeling had been performed. This difference remained significant up to 10 minutes (P<0.01 at t=2, 6 and 10 min). At t=30 min, the intraocular pressure reduction was comparable in both groups.

DISCUSSION

The vitreous plays a fundamental role in the pathogenesis of retinal detachment via peripheral traction. However, since not all tears lead inevitably to retinal detachment, there must also be adherence factors which can prevent the latter. The response to acetazolamide differs significantly in patients undergoing retinal detachment surgery compared with patients treated with epiretinal membrane peeling. In the occurrence of retinal detachment, deficient photoreceptor adherence to the retinal pigment epithelium has been hypothesized. Further research should aim to correlate the tonometric response to acetazolamide with photoreceptor adherence.

Abdominal aortic aneurysm imaging with 3-D ultrasound: 3-D-based maximum diameter measurement and volume quantification

The clinical reliability of 3-D ultrasound imaging (3-DUS) in quantification of abdominal aortic aneurysm (AAA) was evaluated. B-mode and 3-DUS images of AAAs were acquired for 42 patients. AAAs were segmented. A 3-D-based maximum diameter (Max3-D) and partial volume (Vol30) were defined and quantified. Comparisons between 2-D (Max2-D) and 3-D diameters and between orthogonal acquisitions were performed. Intra- and inter-observer reproducibility was evaluated. Intra- and inter-observer coefficients of repeatability (CRs) were less than 5.18 mm for Max3-D. Intra-observer and inter-observer CRs were respectively less than 6.16 and 8.71 mL for Vol30. The mean of normalized errors of Vol30 was around 7%. Correlation between Max2-D and Max3-D was 0.988 (p < 0.0001). Max3-D and Vol30 were not influenced by a probe rotation of 90°. Use of 3-DUS to quantify AAA is a new approach in clinical practice. The present study proposed and evaluated dedicated parameters. Their reproducibility makes the technique clinically reliable.

[Survey of post-graduate training for Dermatology and Venereology residents in France (2005-2010)]

BACKGROUND

Training procedures for dermatology residents have never been evaluated in French university hospitals. The present study describes the methods used over the last 5 years.

METHODS

This was a retrospective survey using a questionnaire sent to French dermatology-residents completing their residency between 2005 and 2010. The data collated included information on theoretical aspects (courses, local, regional or national seminars, meetings) and on practical training (consultations, surgery, laser and cosmetic dermatology), research, post-residency assistantship and additional university diplomas, as well as overall opinions on dermatology training. Statistical analysis was descriptive and comparative according to the number of dermatology teachers (professors, senior lecturers) in the region in which training was given.

RESULTS

One hundred and twenty-two questionnaires were analyzed: 72 from regions with two or less than two university hospital dermatology teachers (group 1) and 50 with more than two such teachers (group 2). Fewer residents had completed a research year in group 1 (19% vs 40%; P=0.01), but the two groups were comparable concerning post-graduate training (DESC) (16%) or post-residency (87%) placement. There were no differences concerning local theoretical training or participation in seminars or meetings, apart from inter-regional seminars, which were more frequent in group 2 (24% vs 3%; P<0.001). There were no differences between the two groups in terms of personal consultations (91%), surgery (62%), laser treatment (13%) or cosmetic dermatology (3%). Satisfaction rates regarding theoretical and practical training were similar in both groups (69% vs 70% and 72% vs 78%, respectively).

DISCUSSION

This is the first survey carried out with the aim of evaluating suitability of training for dermatology residents in France with regard to the "reference" dermatological practice recently submitted to the French health ministry. The present results, obtained from 47% of residents receiving training during this period, show only very few differences concerning dermatology residency training with respect to the number of university hospital dermatology teachers, apart from research training.

CONCLUSION

Despite an overall good opinion on their residency, the dermatology residents involved underlined the need for greater focus on teaching of technical skills (surgery, laser, cosmetic dermatology).

[Time course of digital pressure during dialysis sessions in chronic hemodialysis patients. Prospective observational study of 49 patients]

OBJECTIVES

To describe and compare the evolution of digital pressure on both hands during a dialysis session in patients without digital ischemia, and to identify the parameters influencing the digital pressure.

MATERIALS

Patients with an upper limb vascular access were prospectively included. Digital systolic pressure on the third finger of both hands measured by photoplethysmography and brachial systolic pressure were recorded before dialysis (H0) and every hour (from H1 to H4).

RESULTS

Among 53 patients, 49 were included (exclusions: one surgery for ischemia, one hand tremor, two no consent). None of them had digital ischemia. Digital pressure homolateral to the vascular access was significantly lower compared with controlateral side before and during dialysis. Digital pressure significantly decreased on both sides during dialysis. Brachial pressure decreased significantly compared to H0. Only the brachial pressure decrease was correlated with the decrease of digital pressure. The digital pressure was less than 30 mmHg in six patients. No evidence of digital ischemia was reported after a 6-month follow-up.

CONCLUSION

To our knowledge, this is the first study showing a significant decrease of digital pressure in both hands during hemodialysis in patients without digital ischemia. Further studies are necessary to investigate which parameters can affect digital pressure and to look for clinical consequence of this measurement.

[Cost-effectiveness of lung volume reduction coil treatment in emphysema. STIC REVOLENS]

BACKGROUND

Medical therapeutic options for the treatment of emphysema remain limited. Lung volume reduction surgery is infrequently used because of its high morbi-mortality. Endobronchial lung volume reduction coil (LVRC(®), PneumRx, Mountain View, CA) treatment has been recently developed and has been shown to be feasible and associated with an acceptable safety profile, while resulting in improvements in dyspnea, exercise capacity and lung function. The objective of this study is to analyze the cost effectiveness of LVRC treatment in severe emphysema.

METHODS

This prospective, multicenter study, randomized with a 1:1 ratio (LVRC vs conventional treatment) will include 100 patients who will be followed up for 1year. The primary outcome measure is the 6-month improvement of the 6-minute walk test: the percentage of patients showing an improvement of at least 54m will be compared between groups. A cost-effectiveness study will estimate the cost of LVRC treatment, the global cost of this therapeutic option and will compare the cost between patients treated by LVRC and by medical treatment alone.

EXPECTED RESULTS

This study should allow validating the clinical efficacy of LVRC in severe emphysema. The cost-effectiveness study will assess the medical-economic impact of the LVRC therapeutic option.
