BACKGROUND: The objective was to determine if short term exposure to dry immersion (DI) results in a cephalic fluid shift similar to what has been observed with spaceflight. METHODS: Data were collected from 10 individuals at rest and during the first 2 h of dry immersion. Jugular vein (JV), portal vein (PV), and thyroid volume were measured using 3D echography. Middle cerebral vein velocity (MCVv) was determined using transcranial Doppler ultrasound. The cochlear response to audio stimulation was used to derive an estimate of intracranial pressure (dICP)...

A preterm infant with prenatal diagnosis of hydrops fetalis was spontaneously delivered at 30 weeks of gestational age in a tertiary level hospital. Prenatal echography pointed out severe bilateral pleural effusions and diffused subcutaneous edema. A neonatologist team, alerted at the expulsion stage of labor, assisted the neonate immediately after birth and bilateral hydrothorax was drained with intact placental circulation to avoid a nonrespiratory period and its possible detrimental hemodynamic effects. The newborn was well stabilized in the delivery room before cutting the umbilical cord and starting mechanical ventilation...

The diagnosis of pulmonary thromboembolism (PE) is often delayed because it is usually misdiagnosed as pneumonia or deep vein thrombosis. We report an unusual case of PE misdiagnosed as viral pleuritis on the first arrival at the emergency department (ED) in our hospital. A 14-year-old girl with no previous significant medical history was referred to the ED with pleuritic and chest pain with low-grade fever 4 days before admission.Echography showed a small amount of left pleural effusion. A 12-lead electrocardiogram was normal...

Abdominal pregnancy (AP) accounts for 1% of ectopic implantations. In sub-Saharan Africa, the high prevalence of sexually transmitted infections explains the increasing frequency of this pathology. In Cameroon it rose from 1/10000 deliveries (1995) to 3.3/10000 (2015). Authors herein report a case of a viable abdominal pregnancy discovered at term during emergency laparotomy for suspected uterine rupture. The 24-year-old G2P0 patient was HIV-positive, under antiretrovirals, though AP exceptionally occurs in HIV patients...

Different acute respiratory distress syndrome (ARDS) phenotypes may explain controversial results in clinical trials. Lung-morphology is one of the ARDS-phenotypes and physiological studies suggest different responses in terms of positive-end-expiratory-pressure (PEEP) and recruitment-manoeuvres (RM) according to loss of aeration. To evaluate whether tailored ventilator regimens may impact ARDS outcomes, our group has designed a randomised-clinical-trial of ventilator settings according to lung morphology in moderate-to-severe ARDS (LIVE study)...

BACKGROUND: In recent times, the scientific community has been showing increasing interest in the treatments aimed at slowing the progression of the autosomal dominant polycystic kidney disease (ADPKD). Therefore, in this paper, we test and evaluate the performance of several available methods for total kidney volume (TKV) computation in ADPKD patients - from echography to MRI - in order to optimize patient classification. METHODS: Two methods based on geometric assumptions (mid-slice [MS], ellipsoid [EL]) and a third one on true contour detection were tested on 40 ADPKD patients at different disease stage using MRI...

OBJECTIVES: Extracorporeal membrane oxygenation support is indicated in severe and refractory respiratory or circulatory failures. Neurological complications are typically represented by acute ischemic or hemorrhagic lesions, which induce higher morbidity and mortality. The primary goal of this study was to assess the prognostic value of cerebral tissue oxygen saturation (StcO2) on mortality in neonates and young infants treated with ECMO. A secondary objective was to evaluate the association between StcO2 and the occurrence of cerebral lesions...

BACKGROUND: Human adenovirus 7 (HAdV-7) was responsible for a significant number of fatalities during the 2011 community outbreak in Taiwan. The mechanisms underlying the pathogenesis of severe adenovirus infections in non-immunocompromised individuals remain unclear. Adenovirus pneumonia was associated with pleural effusion in a number of patients from the 2011 outbreak suggesting that similar to bacterial pneumonia, patients diagnosed with adenovirus pneumonia who have pleural effusion are more severely and systemically infected, and may have a more protracted disease course...

The anti-programmed cell-death-1 antibody, nivolumab, has been recently approved for the treatment of advanced non-small cell lung cancer. Although, today, immune-related adverse effects such as dermatologic, digestive, hepatic, and endocrine toxicities are well-known with immune checkpoint inhibitors, rheumatic diseases are less well described. Herein, we report the case of a patient without a history of arthritis who developed polymyalgia rheumatica after 13 cycles of nivolumab used for the treatment of advanced non-small cell lung cancer...

Although interventional devices such as needles, guide wires and catheters are best visualized by X-ray, real-time volumetric echography could offer an attractive alternative as it avoids ionizing radiation; it provides good soft tissue contrast and it is mobile and relatively cheap. Unfortunately, as echography is traditionally used to image soft tissue and blood flow, the appearance of interventional devices in conventional ultrasound images remains relatively poor which is a major obstacle towards ultrasound-guided interventions...
