Patients in Martinique, and specifically those of African descent, show very high levels of EGFR mutation as opposed to what can be found in mainland France or in African Americans. These findings may be ascribed to low tobacco consumption as well as to genetic factors. Systematic screening in patients of African Caribbean origin should be prescribed.

Aim: To analyze the impact of obesity on cardiopulmonary response to exercise in people with chronic post-coronavirus disease 2019 (COVID-19) syndrome. Patients & methods: Consecutive subjects with chronic post-COVID syndrome 6 months after nonsevere acute infection were included. All patients received a complete clinical evaluation, lung function tests and cardiopulmonary exercise testing. A total of 51 consecutive patients diagnosed with chronic post-COVID-19 were enrolled in this study. Results: More than half of patients with chronic post-COVID-19 had a significant alteration in aerobic exercise capacity (VO2peak) 6 months after hospital discharge. Obese long-COVID-19 patients also displayed a marked reduction of oxygen pulse (O2pulse). Conclusion: Obese patients were more prone to have pathological pulmonary limitation and pulmonary gas exchange impairment to exercise compared with nonobese COVID-19 patients.

Despite a higher frequency of EGFR mutations in African-Caribbean patients, ethnicity was not an independent factor of OS in lung adenocarcinoma. Lower initial PS in this mainly non-smoking African-Caribbean population may explain the absence of a difference in OS.

Obesity-hypoventilation syndrome (OHS) is associated with many comorbidities. The aim of this study was to evaluate the association between previous continuous positive airway pressure (CPAP) and the prevalence of comorbidities in OHS associated with obstructive sleep apnea (OSA). We performed a retrospective, single-center study at the University Hospital of Martinique, the referral hospital for the island of Martinique. A total of 97 patients with OHS associated with severe OSA on non-invasive ventilation (NIV) were included; 54 patients (56%) had previous treatment of OSA with a positive airway pressure (PAP) device before shifting to NIV (PAP group) and 43 (44%) had no previous treatment of OSA with a PAP device before initiating NIV PAP (no PAP group). Sociodemographic characteristics were similar between groups; there were 40 women (74%) in the PAP group versus 34 (79%) in the no PAP group, mean age at OHS diagnosis was 66 ± 15 versus 67 ± 16 years, respectively, and the mean age at inclusion 72 ± 14 versus 71 ± 15 years, respectively. The average number of comorbidities was 4 ± 1 in the PAP group versus 4 ± 2 in the no PAP group; the mean Charlson index was 5 ± 2 in both groups. The mean BMI was 42 ± 8 kg/m2 in both groups. The mean follow-up duration was 5.8 ± 4.4 years in the PAP group versus 4.7 ± 3.5 years in the no PAP group. Chronic heart failure was less common in patients who had a previous PAP 30% versus 53% (p = 0.02). It is also noted that these patients were diagnosed less often in the context of acute respiratory failure in patients with previous PAP: 56% versus 93% (p < 0.0001). In contrast, asthma patients were more frequent in patients with previous treatment of OSA with a PAP device at the time of OHS diagnosis but not significantly: 37% versus 19% (p = 0.07). Early treatment of severe OSA with a PAP device prior to diagnosis of OHS seems to be associated with a reduced prevalence of cardiac diseases, notably chronic heart failure, in patients diagnosed with OHS associated with severe OSA.

Mammomonogamosis is a parasitosis caused by a nematode of the genus Mammomonogamus. This parasitosis persists in certain tropical areas, particularly the Caribbean, despite the improvement in the living conditions of the populations. The main symptomatology is cough, which may be accompanied by some general signs and hypereosinophilia. The worms are found in the course of bronchial endoscopy. Patients receive antiparasitic treatment after the extraction.This parasitosis can infect tourists who are frequent in the region.It is important not to ignore such a diagnostic hypothesis when faced with an unexplained cough in a person who has stayed in an endemic area.

Tracheal tumour is rare but can lead to upper airway obstruction and acute respiratory distress. Its management includes surgical resection, radiotherapy or interventional bronchoscopy. Ventilation or difficulties with tracheal intubation can occur during the peri-operative course resulting in serious adverse consequences. We report the case of an 83-year-old man with an obstructive tracheal chondrosarcoma resected by rigid bronchoscopy undergoing veno-venous extracorporeal membrane oxygenation. Such support should be considered when the patient's airway patency cannot be ensured by conventional methods.

Introduction Histoplasmosis is a fungal disease caused by Histoplasma capsulatum. Histoplasma capsulatum var capsulatum is found in Martinique. Cluster cases following working in deserted house, have been described in Martinique. Cases of acute pulmonary histoplasmosis have been described in immunosuppressed individuals, or in case of substantial exposure to reservoirs of Histoplasma capsulatum; however, cases of acute histoplasmosis are rare in immunocompetent individuals. Cases series We report a series of 4 cases of sporadic acute pulmonary histoplasmosis in immunocompetent subjects. Investigation revealed definite exposure in one patient and 3 cases with potential exposure. The diagnosis was microbiological and histological in 3 patients and histological in one patient. All subjects had positive serology to histoplasmosis. Pulmonary involvement was in the form of nodules and micronodules in 3 cases and ground glass lesions in one case. Patients were treated with itraconazole for 3 months and all had a favourable outcome. Conclusion We report a series of 4 cases of acute pulmonary histoplasmosis in immunocompetent individuals, occurring in a context where exposure was uncertain. This raises the problem of occult exposure in the Caribbean. Interventions to raise awareness and encourage caution are warranted targeting the population of the French West Indies and French Guiana.
