[Short antibiotic therapy in hospitalized pneumonia: A cohort study]. / Antibiothérapie courte au cours de la pneumonie : PNEUMOSHORT.

INTRODUCTION: Pneumonia is one of the most common indications for antibiotic. Shortening the duration of antibiotic therapy should help reduce bacterial resistance. To date, three randomized control trials have shown non-inferiority of short courses of antibiotic therapy (3 days) compared with 7 days in non-severe pneumonia. The aim of this study was to assess this strategy in real life. METHOD: This retrospective observational cohort study included all patients with pneumonia hospitalized in an internal medical ward from 11/01/2022 to 05/31/2023. We implemented the strategy based on early discontinuation of antibiotic therapy in patients with pneumonia who were clinically stable after 3 days of ß-lactam treatment. RESULTS: Among 49 patients included, median age was 72, median antibiotic duration was 4 days (IQR 3-6), and cure rate at D30 was 88 %. At day 30, we observed one death (2 %), four new antibiotic therapy (9 %), and two new hospitalisation (5 %), among five immunosuppressed patients. Among immunosuppressed patients (n=17; 35 %), failure rate was three times higher in case of short antibiotic courses (3/8; 38 %) than long antibiotic courses (1/7; 14 %). CONCLUSION: Strategy based on early discontinuation of antibiotic therapy in immunocompetent patients with pneumonia who were clinically stable after 3 days of ß-lactam treatment is safe, and easy to implement in a medical ward.

[Pulmonary fibrosis associated with hereditary fibrosing poikiloderma caused by FAM111B mutation: A case report]. / Fibrose pulmonaire au cours de la poïkilodermie héréditaire sclérosante associée à la mutation du gène FAM111B : à propos d'un cas.

INTRODUCTION: Hereditary fibrosing poikiloderma with tendon contractures, myopathy and pulmonary fibrosis (POIKTMP) is a recently described, extremely rare, entity belonging to the spectrum of inherited poikilodermas. It is provoked by a mutation of the FAM111B gene. Respiratory involvement has never been fully described but usually involves a restrictive respiratory pattern. We present here a case of pulmonary fibrosis associated with POIKTMP and describe the clinical, functional, radiological and evolutionary characteristics. OBSERVATION: A 38 year-old patient with poikiloderma diagnosed in childhood was referred on account of dyspnoea. Initial evaluation showed a diffuse, fibrosing, interstitial pneumonitis with upper lobe predominance, associated with severe muscular involvement on imaging that remained sub-clinical during the evolution of the disease. Lung function impairment was severe and a rapid worsening of the pulmonary fibrosis and an acute exacerbation led to death after a follow-up of 21 months. CONCLUSION: This case illustrates the fibrosing pulmonary involvement associated with POIKTMP and confirms its extreme severity. It is found only in adults and is universally fatal after a variable time. It highlights the necessity for a systematic screening as soon as the diagnosis of POIKTMP is confirmed in order to establish specialised respiratory management.

Predicting the risk of cancer after unprovoked venous thromboembolism: external validation of the RIETE score.

Essentials Patients at high-risk of occult cancer may benefit from extensive screening. We validated the RIETE cancer score in the MVTEP study. One in three patients were classified as high-risk, 10% of whom had cancer diagnosed. The RIETE score identifies a subgroup at high risk for cancer. SUMMARY: Background Most recent trials evaluating extensive screening strategies for occult cancer in patients with unprovoked venous thromboembolism have failed, because, among other reasons, of an overall low rate of occult cancer. The RIETE investigators recently proposed a score aimed at identifying a subgroup at higher risk. Methods We retrospectively computed the RIETE score for all patients included in the MVTEP study, which evaluated the accuracy of [¹8F]fluorodeoxyglucose-positron emission tomography in the screening of occult cancer in patients with unprovoked venous thromboembolism. Performance of the RIETE score was assessed according to the proportion of patients classified in each risk group, and the corresponding rates of cancer diagnosis. Results Among the 386 patients included in the analysis, 136 patients (35.3%) were classified as high risk by the RIETE score. Cancer was diagnosed in 16 (11.8%) of them, whereas it was diagnosed in nine (3.6%) of the 250 patients with a low RIETE cancer score: odds ratio of 3.6 (95% confidence interval [CI] 1.53-8.32). The area under the receiver operating characteristic curve was 0.63 (95% CI 0.51-0.74). Conclusion The RIETE score seems to be able to identify a subgroup at high risk for cancer (10%) in our specific dataset of patients with unprovoked venous thromboembolism.

[Pleural effusion: diagnosis and management]. / Orientation diagnostique et conduite à tenir devant un épanchement pleural.

Pleural effusion management is a common clinical situation associated with numerous pulmonary, pleural or extra-pulmonary diseases. A systematic approach is needed to enable a rapid diagnosis and an appropriate treatment. Pleural fluid analysis is the first step to perform which allows a presumptive diagnosis in most cases. Otherwise, further analysis of the pleural fluid or thoracic imaging or pleural biopsy may be necessary. This review aims at highlighting the important elements of the work-up required by a pleural effusion.
