RESUMO
Lung cancer is the third most common cancer in Belgium in 2017 and remains the leading cause of cancer death worldwide. There is no longer any doubt that the main cause of lung cancer is smoking. However, the prevalence of lung cancer in never-smokers has been increasing overtime. Moreover, it is now recognized that the lung cancer of non-smoker patients has very distinct characteristics. In this retrospective cohort study (N = 520), we describe the characteristics of non-smoker patients and their non-small cell lung carcinoma and compare them to those of smokers. The patients included in this study were whose with a new diagnostic of lung cancer made at the Liège University Hospital of Liège over 2 years round. Non small cell lung cancer occurring in never-smokers patients is more often seen in young and very old patients, more frequent in female, essentially adenocarcinoma and often associated with mutations. This work confirms that lung cancer in never-smokers shows different features than lung cancer seen in patients with a smoking history.
Le cancer pulmonaire est le troisième cancer le plus fréquent en Belgique en 2017 et reste la première cause de décès par cancer dans le monde. Il ne fait plus aucun doute que la cause principale de cancer du poumon est le tabagisme. Il est toutefois apparu, ces dernières décennies, que le pourcentage de patients non fumeurs augmente parmi les patients présentant un cancer du poumon. Par ailleurs, il est dorénavant reconnu que le cancer pulmonaire du patient non fumeur présente des caractéristiques bien distinctes. Dans ce contexte, nous présentons une étude rétrospective reprenant les caractéristiques cliniques et néoplasiques de l'ensemble des patients ayant présenté un carcinome pulmonaire non à petites cellules dans notre institution sur une période de 2 ans (N = 520). Les cancers non à petites cellules observés chez les nonfumeurs sont plus fréquents chez les sujets jeunes ou très âgés, plus fréquents dans le sexe féminin, en très grande majorité des adénocarcinomes, et souvent associés à des mutations. Nous confirmons ainsi qu'il s'agit d'un cancer aux caractéristiques différentes des cancers pulmonaires des patients fumeurs.

Empyema and subacute invasive aspergillosis are rare pathologies that should not be overlooked because of the need for early treatment and a different management of bacterial infections which are more frequent. We report the case of a 75-year-old man with subacute invasive aspergillosis and an empyema following drowning and cardiopulmonary arrest.
L'empyème à Aspergillus fumigatus et l'aspergillose invasive subaiguë sont des pathologies rares à ne pas méconnaître au vu de la nécessité d'un traitement précoce et d'une prise en charge différente des infections pleuropulmonaires bactériennes qui sont plus fréquentes. Nous rapportons le cas d'un patient de 75 ans présentant une aspergillose invasive subaiguë, associée à un empyème, dans les suites d'une noyade avec arrêt cardiopulmonaire.

AFP was assayed in serum of normal pregnant women and in patients with pathological pregnancy. Pathological levels of AFP, defined as increased or decreased concentrations compared with the normal distribution, was detected in 83.5 % of pregnant women who delivered a dysmature child and in 88 % of those whose placenta was macroscopically sclerous. A longitudinal determination of AFP appears to be useful in the follow-up of risk of abortion.

AFP can be measured by radioimmunoassay in 52 hours using an incubation at 18 degrees C for 48 hours and the double antibody solid phase method to separate the free labelled AFP from the labelled AFP bound to the antibodies. In these conditions, the sensitivity and precision of the assay are very satisfactory and the results are directly in correlation with the results obtained using the classical double antibody method. In the serum of normal people, except pregnant women, the concentration of AFP is not detectable or is less than 20 ng/ml. In the serum of pregnant women, AFP increases from the 8th. week of gestation to the 32nd., then stabilises or gradually decreases.
