Longitudinal course of lung function in myotonic dystrophy type 1.

Introduction: Quality of life and prognosis among patients with myotonic dystrophy type 1 (DM1) depend on the degree of respiratory impairment. However, the changes over time in pulmonary function in DM1 have not been clearly described.

Methods: We retrospectively reviewed pulmonary function tests of 80 DM1 patients followed for at least 5 years.

Sleep Management Strategy and Performance in an Extreme Mountain Ultra-marathon.

We intended to assess the relationship between sleep strategies and performance during the North-Face Ultra-Trail du Mont-Blanc 2013, to test the hypothesis that sleep management can influence athletic performance. Almost all runners specifically adopted sleep management strategies before the race. Among the finishers 72% didn't sleep at all during the race and 28% took a least one break for sleep.

Lack of correlation between the ventilatory response to CO2 and lung function impairment in myotonic dystrophy patients: evidence for a dysregulation at central level.

Myotonic dystrophy Type 1 (DM1) is the most common muscular dystrophy in adults. Respiratory failure is common but clinical findings support a dysregulation of the control of breathing at central level, furthermore contributing to alveolar hypoventilation independently of the severity of respiratory weakness. We therefore intended to study the relationship between the ventilatory response to CO2 and the impairment of lung function in DM1 patients.

Contribution of DNA ploidy image cytometry to the management of ASC cervical lesions.

Background: The Bethesda system classifies smears that suggest an underlying cervical intraepithelial neoplasia (CIN) as ASC (atypical squamous cell) smears. ASC smears are subdivided into ASCUS (of undetermined significance) and ASCH (cannot exclude a high-grade lesion). Today the management of ASCUS is a triage with HR-HPV testing and colposcopy is recommended for ASCH.

Usefulness of DNA ploidy measurement on liquid-based smears showing conflicting results between cytology and high-risk human papillomavirus typing.

To improve the positive predictive value (PPV) for high-risk human papillomavirus (HR-HPV) in primary screening, DNA ploidy was measured on the same liquid-based sample by image cytometry in 984 cases showing discrepancies between cytology and HR-HPV testing. Of the conflicting results, 14.5% corresponded to a cytologic lesion (from atypical squamous cells of undetermined significance to high-grade squamous intraepithelial lesion [HSIL]) without HPV detected, and 85.
