[Survival and epidemiological characteristics of women with lung cancer in Reunion]. / Survie et caractéristiques épidémiologiques des femmes atteintes de cancer pulmonaire à La Réunion.

Lung cancer is a common disease throughout the world, representing the main cause of death from cancer. Its incidence in the female population is increasing. In metropolitan France and Reunion Island, the main risk factor remains tobacco smoking. However, environmental, genetic and hormonal factors appear to play a role in bronchial oncogenesis and the survival of affected women is better than that of men. We studied retrospectively the survival and characteristics of a cohort in Reunion Island, diagnosed with lung cancer between January 2017 and December 2018. In total, 501 patients were included over the period including 166 women. The median overall survival was 23 months in women against 11 months in men (P<0.0005). Male sex has been identified as a poor prognostic factor for overall survival (HR=1.338; 95% CI=1.007-1.778) regardless of disease stage. Women smoked less often than men 85.4% of them had adenocarcinoma, with more EGFR mutations than men, and their environmental exposures were lower. The female population of Reunion Island in our study had better overall survival than the men. Smoking status, environmental exposures, histological and molecular characteristics varied by sex.

[Pulmonary embolism: the extent of computerized tomography]. / Embolie pulmonaire : faut-il tendre vers le << tout angioscanner >> ?

The use of computerised tomography in the diagnosis of pulmonary embolism has been the subject of clinical research while, at the same time, technical progress has provided the current multidetector-row spiral equipment. Computerised tomography has been assessed both with respect to reference strategies as well as in extensive pragmatic trials. The preliminary evaluation of the clinical probability and the assay of d-dimers has progressively become imperative. The value of the venous doppler ultrasound of the legs, in particular in the elderly, is limited by the variable accessibility according to the centre. In rare cases, uncertainty persists, for example with a good quality negative multidetector-row spiral computerised tomography associated with a high clinical probability, leaving room for complementary explorations. The confrontation between clinicians and radiologists is then all the more pertinent.

[Diagnosis and care of postembolic pulmonary hypertension: the role of the pneumologist]. / Diagnostic et prise en charge de l'hypertension pulmonaire postembolique : le rôle du pneumologue.

The prognosis of postembolic pulmonary hypertension, a rare and serious disease, has been transformed with the curative intervention of pulmonary endarteriectomy. The screening is based on two key non invasive examinations, the cardiac ultrasound and ventilation-perfusion scintigraphy. The confirmation of the diagnosis and the determination of the best therapeutic options then relies on the expertise of the national reference centre, based on the haemodynamics and the morphological data provided by pulmonary angiography and spiral computerised tomography. Although the technique of endarteriectomy is fully validated, a drug approach is in the assessment process, both in the inoperable forms or when confronted with persistent postsurgical pulmonary hypertension.

[A bilateral diaphragmatic paralysis due to Parsonage and Turner syndrome--its evolution over eight years]. / Paralysie diaphragmatique bilatérale imputable à un syndrome de Parsonage-Turner. Evolution à huit ans.

The diaphragmatic paralysis is a rare disease whose causes and evolving forms are numerous. We report the development to eight years of paralysis diaphragmatic bilateral attributed to a Parsonage-Turner syndrome: the lack of recovery is proved by respiratory functional follow-up. The therapeutic possibilities, limited, are discussed.

[Self medication with Annona muricata L. (corossol) as an anti-cancer agent in Reunion]. / Automédication par Annona muricata L. (corossol) à visée anticancéreuse à la Réunion.

INTRODUCTION: Annona muricata L. also called soursop, graviola, guanabana and sapoty (French creole) is a fruit tree growing in tropical countries. The fruits, seeds, leaves and roots are used in traditional medicine. Potential anticancer effects encourage patients to consume this product as self medication. The object of the study was to determine the prevalence of use of graviola as an anticancer agent by patients treated for a lung cancer. METHODS: Our survey took place in two thoracic oncology day cares units of the university hospital of Reunion. All the patients treated by chemotherapy and immunotherapy for lung cancer were asked the same questions in a face to face interview over a 6-month period. RESULTS: One hundred questionnaires were collected. Sixty seven patients consumed graviola. In 53.7%, graviola was consumed as an anticancer agent and 25 patients took it regularly. Most often graviola was ingested as an infusion of boiled leaves (69.5%). The supply was exclusively local. CONCLUSIONS: A quarter of patients treated by chemotherapy for a lung cancer in Reunion consume graviola regularly as self medication. The consequences of this intake, drug interactions and side effects are unknown and would be interesting to identify.
