Necrotizing fasciitis within a 5-week-old infant: A silly demonstration.
Pulmonary fibrosis is a pathological entity still too little understood today, burdened with significant morbidity and mortality. Idiopathic pulmonary fibrosis is a complex diagnostic disease requiring a multidisciplinary approach and in some cases the performance of a lung biopsy. In addition, the early identification of the pathology remains the key in order to preserve lung function as much as possible. In this context and in view of the diagnostic difficulty, it seems essential to identify new biomarkers to help with the differential diagnosis, the evaluation of the prognosis and the response to treatment. In addition, the evolution of the pathology remaining inexorable despite anti-fibrotic treatments, it appears critical to be able to identify new potential therapeutic routes.Diffuse bilateral uveal melanocytic proliferation is a rare paraneoplastic ophthalmologic syndrome. The increase in life expectancy in oncology partly explains the gradual increase in its incidence. In almost half of the cases, the syndrome manifests itself before the diagnosis of primary neoplasia. It should be suspected in cases of bilateral uveal pigmented lesions that do not meet the clinical criteria for other known eye pathologies. Legal blindness occurs for the majority of patients during the first year after the initial clinical presentation. Death, due to the severity of the underlying pathology, occurs statistically within three years. Here we display the case of such a diffuse bilateral uveal melanocytic proliferation in a patient with relapsed colonic adenocarcinoma, initially treated for age-related macular degeneration.POEMS syndrome is a rare and invalidating entity characterized by polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy and dermatoses. The diagnosis of this condition is often late and challenging due to the heterogeneity of clinical forms. The light chains secreted by the clonal plasmocytes cause overproduction of VEGF (Vascular Endothelial Growth Factor) responsible for the appearance of the clinical manifestations of POEMS. The diagnostic approach is based on different clinical and biological criteria. Patients with a solitary plasmacytoma are candidates for radiotherapy treatment. Patients with diffuse bone involvement or bone marrow infiltration are best treated by systemic drugs. The response to treatment may take several months before clinical and biological improvement. Early diagnosis and dedicated management limit the clinico-functional impact of POEMS.Both obesity and type 2 diabetes (T2D) are recognized risk factors for developing a more severe form of COVID-19, with a higher death rate. Metformin is considered as the first-line medication for the treatment of T2D, especially in obese patients. Beyond its glucose-lowering activity, metformin exerts pleiotropic effects, among which an anti-inflammatory effect that could be beneficial. However, metformin is contraindicated in case of severe renal insufficiency, liver failure and/or unstable heart failure, because of a risk of lactic acidosis. Yet, COVID-19, besides the well-known pneumonia that can be responsible for severe hypoxemia, may be associated with multisystemic organ failure, among which kidneys, liver and heart. Thus, the question arises whether metformin, which represents the background therapy in above 80 % of patients with T2D, should be continued in patients exposed to SARS-CoV-2 or instead be stopped. selleckchem This article summarizes the most important results of observational studies, which all argue for a beneficial effect of metformin therapy that is associated with a significant reduction in mortality among hospitalized patients with T2D due to COVID-19. Finally, some practical advices will be given.Tracheomalacia (TM) is characterized by tracheal collapse due to an intrinsic anomaly resulting in a lack of rigidity of the cartilaginous rings and/or the posterior membrane during expiration, coughing or crying. It may also be secondary to external compression or acquired during endobronchial diseases. TM is commonly associated with other syndromes or airway abnormalities. Tracheomalacia can be localized or diffused and if the main bronchi are involved, the term of tracheobronchomalacia (TBM) is used. The most common symptoms include expiratory stridor, barking cough and recurrent respiratory tract infections. If tracheal weakness is severe, Acute Life Threating Events (ALTE) or Brief Resolved Unexplained Event (BRUE) can occur. While mild forms usually do not require any treatment, severe TBM may require medical and/or surgical management. Amongst several possible treatments, including tracheostomy, noninvasive ventilation and airway stenting, the pexy surgical approach (posterior, anterior tracheopexy or aortopexy) is currently the favoured option.Presence of air in the spinal canal, called pneumorrhachis (PR) is a rare and likely unrecognized condition often due to traumatic or iatrogenic causes. Most of PR occur after repeated epidural ponction or penetrating trauma or brutal intra-alveolar increase especially in asthma attack. Non traumatic and non iatrogenic causes are uncommon but can appear in a neoplastic context.
To evaluate the effect of withdrawing ixekizumab in patients with psoriatic arthritis (PsA) who had achieved minimal disease activity (MDA) after open-label ixekizumab treatment.

SPIRIT-P3 was a multicenter, randomized, double-blind withdrawal study that enrolled biologic-naive adult patients with PsA to open-label ixekizumab (160 mg at week 0, 80 mg every two weeks [IXE Q2W]) for 36 weeks. Patients sustaining MDA for >3 consecutive months were randomized (between weeks 36-64) 11 to blinded IXE Q2W withdrawal (placebo) or continued IXE Q2W treatment up to week 104. The primary efficacy endpoint was time to relapse (loss of MDA) for randomized patients. Patients who relapsed were retreated with IXE Q2W until week 104.

A total of 394 patients were enrolled and received open-label IXE Q2W. Of those, 158 (40%) patients achieved sustained MDA and were randomized to IXE Q2W withdrawal (placebo; N=79) or continued IXE Q2W treatment (N=79). Patients relapsed more rapidly with treatment withdrawal (median 22.
