RESUMEN
Acute respiratory failure (ARF) is a leading cause, along with sepsis, of admission to the intensive care unit (ICU) of patients with active cancer. Presenting variable clinical severity, ARF in onco-hematological patients has differing etiologies, primarily represented by possibly opportunistic acute infectious pneumonia (de novo hypoxemic ARF), and decompensation in chronic cardiac or respiratory diseases (e.g., acute pulmonary edema or exacerbated chronic obstructive pulmonary disease). In these patients, orotracheal intubation is associated with a doubled risk of in-hospital mortality. Consequently, over the last three decades, numerous researchers have attempted to demonstrate and pinpoint the precise role of non-invasive ventilation (NIV) in the specific context of ARF in onco-hematological patients. While the benefits of NIV in the management of acute pulmonary edema or alveolar hypoventilation (hypercapnic ARF) are well-demonstrated, its positioning in de novo hypoxemic ARF is debatable, and has recently been called into question. In the early 2000s, based on randomized controlled trials, NIV was recommended as first-line treatment, one reason being that it allowed significantly reduced use of orotracheal intubation. In the latest randomized studies, however, the benefits of NIV in terms of survival orotracheal intubation have not been observed; as a result, it is no longer recommended in the management of de novo hypoxemic ARF in onco-haematological patients.

BACKGROUND: Hemophagocytosis during Q fever (QF) and Mediterranean spotted fever (MSF) is rare and only a few cases have been reported. We aimed to investigate the characteristics, outcome, and treatment of QF/MSF-associated hemophagocytosis. METHODS: We retrospectively reviewed all patients with a diagnosis of QF or MSF and suspected hemophagocytic syndrome (HS), according to Henter's criteria, between 2002 and 2011, and compared the latter to patients without HS or with lymphoma-associated HS. RESULTS: Seventeen patients with HS (median age 42 years, range 5-68 years; five females (29%)) with QF (n=8) and MSF (n=9) were included in this study. When comparing patients with QF- and MSF-associated HS with patients without HS (n=11), HS-associated signs (splenomegaly, ferritinemia, hypertriglyceridemia, and cytopenia) were significantly more frequent in patients with histological HS (p<0.05), along with a greater number of Henter's criteria. Despite the presence of HS-associated signs, treatment was similar in these two subgroups, including the time to recovery and the outcome. When compared to lymphoma-associated HS (n=10), the outcome in QF/MSF-associated HS was significantly different, with mortality in 70% of lymphoma patients versus none in QF- and MSF-associated HS (p<0.05). CONCLUSION: Hemophagocytosis is a rare occurrence during the course of QF and MSF. The presence of profound cytopenia is quite unusual in QF and MSF and should bring to mind the presence of associated HS. Nevertheless, hemophagocytic syndrome is associated with a good outcome in this condition.

The principal digestive anomalies detected by radiological examination in dermatomyositis are the motor and functional consequences of the smooth and striated muscle lesions in these tissues. Vascular changes cause ulcerations, located in any part of the digestive tract, but more frequently in the esophagus, duodenum, and small intestine. These ulcerations sometimes develop into pseudodiverticulae.
