Exploring the time course of painful post-traumatic trigeminal neuropathy: a pilot study

Patients suffering from painful post-traumatic trigeminal neuropathy (PTTN) often report circadian variations in pain. This pilot study aimed to assess the daily evolution of pain in patients fulfilling the following criteria: PTTN diagnosed based on ICHD-3 criteria; >18 years of age; no impairment in communication and signed informed consent. Primary study outcome was a self-declared quantitative assessment of pain intensity using an 11-point numerical scale (0–10) for 8 consecutive days. Impact on oral function and quality of life was also assessed, using psychometric questionnaires GOHAI and HADS. Eleven patients with PTTN were recruited (mean age: 66.1 ± 6.8 years old). Mean pain intensity was 3.6 ± 0.99. Mean pain intensity increased progressively and significantly during the day, from 1.8 ± 1.3 to 4.6 ± 2.3 (p < 0.0001). Mean HADS score was 7.8 ± 2.7. Mean GOHAI score was weak (35/60). In conclusion, PTTN seems to follow a circadian rhythm

Effect of bar designs on peri implant tissues health in implant-supported removable prostheses: a systematic review

Abstract Different characteristics of bars (cross-sectional shape, diameter, distal extension etc.) lead to different biomechanical behavior (retention and stress) with implants and peri-implant tissues. Aim: To evaluate the impact of implant-supported removable prostheses bar designs in fully edentulous arch (in the maxilla and/or mandibula), with 4 implants or more, on the peri-implant soft and hard tissues. Two reviewers searched for observational studies, RCT and in vitro studies, published on five main databases and three from the grey literature, without restrictions on November 2023. Of the 3049 selected articles, four met the inclusion criteria. Four RCT evaluated peri-implant health tissues in full edentulous arches with 4 or 6 implants rehabilitated with implant bar overdentures. One prospective study with 5 years follow-up evaluated the success/survival rate of implants and implant bar overdentures. Overall, 261 subjects were enrolled in our systematic review with 1176 implants. Overdentures’ survival rate was 100%. There was a trend that plaque indices and gingival indices were low in all of the studies, however no statistical analysis was done due to the lack of information. Due to the lack of information in the included studies, we cannot confirm if bar characteristics affect the peri-implant tissues health

French recommendations for the management of systemic sclerosis

International audienceSystemic sclerosis (SSc) is a generalized disease of the connective tissue, arterioles, and microvessels, characterized by the appearance of fibrosis and vascular obliteration. There are two main phenotypical forms of SSc: a diffuse cutaneous form that extends towards the proximal region of the limbs and/or torso, and a limited cutaneous form where the cutaneous sclerosis only affects the extremities of the limbs (without passing beyond the elbows and knees). There also exists in less than 10% of cases forms that never involve the skin. This is called SSc sine scleroderma. The prognosis depends essentially on the occurrence of visceral damage and more particularly interstitial lung disease (which is sometimes severe), pulmonary arterial hypertension, or primary cardiac damage, which represent the three commonest causes of mortality in SSc. Another type of involvement with poor prognosis, scleroderma renal crisis, is rare (less than 5% of cases). Cutaneous extension is also an important parameter, with the diffuse cutaneous forms having less favorable prognosis
