Pulmonary arteriovenous malformations (PAVMs) are structurally abnormal vascular communications that provide a continuous right-to-left shunt between pulmonary arteries and veins. Their importance stems from the risks they pose (>1 in 4 patients will have a paradoxical embolic stroke, abscess or myocardial infarction while life-threatening haemorrhage affects 1 in 100 women in pregnancy), opportunities for risk prevention, surprisingly high prevalence and under-appreciation, thus representing a challenging condition for practising healthcare professionals...

BACKGROUND: In the regular wildlife monitoring action carried out in the summer of the past few years at the Berlenga Island, wild rabbits (Oryctolagus cuniculus) have been repeatedly found dead. However, the origin of those deaths was never investigated. Our aim was to investigate the cause of death of 11 rabbits collected between April and May 2016. RESULTS: While screening samples from rabbit carcasses for the major viral rabbit pathogens, five tested positive to RHDV2 but all were negative for RHDV and myxoma virus (MYXV)...

Invasive fungal disease represents one of the severe complications in haematopoietic stem cell transplant recipients. We describe a case of a patient treated for relapse of chronic lymphoblastic leukaemia 6 years after HSCT. The patient was treated for invasive pulmonary aspergillosis but died 3 months later from multiple organ failures consisting of haemorrhagic necrotizing fungal pneumonia, refractory chronic hepatic graft versus host disease and cytomegalovirus hepatitis. Autopsy samples revealed histopathological evidence of fungal hyphae and an unusual Aspergillus nidulans-like species was isolated in pure culture...

AIM: To establish if labour and gestational age have an additive effect on the likelihood of newborn respiratory complications. METHODS: Case-control study on singleton pregnancies, delivered between 34 and 41 weeks. Cases were collected among newborns discharged with diagnoses of respiratory complications, as codified by ICD 9 1997. Subsequently, pneumonias, meconium aspiration syndromes, and pulmonary haemorrhage were excluded. Controls were all other newborns without respiratory complications...

Although thoracic ablative therapies are generally safe procedures, fatal complications can occur. Bevacizumab is a standard-of-care treatment along with chemotherapy for metastatic colorectal cancer. Although uncommon, unpredictable serious adverse events can occur secondary to bevacizumab. We report a case of fatal intrapulmonary haemorrhage as a result of arteriopulmonary fistula in a patient after microwave ablation of pulmonary colorectal cancer metastasis while on bevacizumab. Antiangiogenetic properties of bevacizumab are associated with delayed wound healing, which might have been a crucial factor in the development of arteriopulmonary fistula and haemorrhage...

Hantaviruses are a group of antigenically distinct viruses carried out in rodents and insectivores. Humans are accidental hosts and get infected by aerosols generated from contaminated urine, faeces and saliva of infected rodents. Hantaviruses are identified as aetiological agents of two human diseases, haemorrhagic fever with renal syndrome and hantavirus pulmonary syndrome. Hantavirus causing pulmonary renal disease has rarely been reported in children in India. Hantavirus infection is uncommon under the age of 12 years...

OBJECTIVES: Right ventricular (RV) failure complicating left ventricular assist device implantation is associated with increased mortality. Despite a lack of supporting evidence, venoarterial extracorporeal membrane oxygenation (ECMO) support is increasingly being used as an alternative to traditional temporary RV support. We report our institutional experience with ECMO-facilitated RV support after left ventricular assist device implantation. METHODS: We retrospectively reviewed the concept of temporary ECMO support for perioperative RV failure in 32 consecutive left ventricular assist device (mean age 52 ± 14 years; male 84...

Mutations of the COPA gene cause an immune dysregulatory disease characterised by polyarticular arthritis and progressive interstitial lung disease with pulmonary haemorrhages. We report the case of a young girl that presented at age 3 with polyarticular arthritis, chronic cough and high titer rheumatoid factor. Radiologic imaging showed interstitial lung disease with tree-in-a-bud nodules and air-filled cysts. Targeted genetic analysis of COPA gene showed the reported c.698G>A mutation. The patient was lost to follow up for 3years during which therapy was discontinued with the development of joint damage and deformities...

OBJECTIVES: Computed tomography (CT) is the modality of choice to characterise pulmonary arteriovenous malformations (PAVMs) in patients with hereditary haemorrhagic telangiectasia (HHT). Our objective was to determine if CT findings were associated with frequency of brain abscess and ischaemic stroke. METHODS: This retrospective study included patients with HHT-related PAVMs. CT results, i.e. PAVM presentation (unique, multiple, disseminated or diffuse), the number of PAVMs and the largest feeding artery size, were correlated to prevalence of ischaemic stroke and brain abscess...

BACKGROUND: Different pulmonary hypertension (PH) mechanisms are associated with hereditary haemorrhagic telangiectasia (HHT). METHODS AND RESULTS: We conducted a retrospective study of all suspected cases of PH (echocardiographically estimated systolic pulmonary artery pressure [sPAP] ≥ 40 mmHg) in patients with definite HHT recorded in the French National Reference Centre for HHT database. When right heart catheterization (RHC) was performed, PH cases were confirmed and classified among the PH groups according to the European guidelines...

Children with systemic lupus erythematosus (SLE) generally undergo a pretreatment kidney biopsy. However, some of these patients, especially those with antiphospholipid syndrome (APS), may experience serious coagulopathic complications. We report herein two cases of paediatric SLE with APS in which, despite normal blood test results, the disparate coagulopathic complications of haemorrhage and embolism developed following a kidney biopsy. Case 1 was, an 8-year-old male in whom, primary APS was initially diagnosed...

BACKGROUND: Anticoagulants are recommended for the prevention of stroke/systemic embolism for most patients with atrial fibrillation (AF) and for the treatment of patients with venous thromboembolism (VTE). Regulatory-driven randomized trials, however, typically exclude extreme patient scenarios involving, for instance, severe bleeding, ischaemic risk, frailty or renal impairment, despite their common occurrence in clinical practice. Uncertainty in the management of such cases leads to a high degree of variability in therapeutic approaches...

INTRODUCTION: PPARβ/δ agonists are known to modulate the systemic inflammatory response after sepsis. In this study, inflammation modulation effects of PPARβ/δ are investigated using the selective PPARβ/δ agonist (GW0742) in a model of haemorrhagic shock (HS)-induced sterile systemic inflammation. METHODS: Blood pressure-controlled (35±5mmHg) HS was performed in C57/BL6 mice for 90min. Low-dose GW0742 (0.03mg/kg/BW) and high-dose GW0742 (0.3mg/kg/BW) were then administered at the beginning of resuscitation...

BACKGROUND: Due to the high prevalence of EIPH in racehorses and its potential impact on the horse's health, furosemide administration is permitted up to 4-h prior to post time in most North American racing jurisdictions. Anecdotal reports suggest that administration of furosemide 24-h prior to strenuous exercise may be equally effective in decreasing the severity of EIPH. OBJECTIVES: (1) compare the efficacy of furosemide in reducing the presence and severity of EIPH when administered 4 or 24-h prior to strenuous exercise (2) characterise electrolyte and blood parameters following administration of furosemide at 4- and 24-h prior to exercise...

Leptospiroses are worldwide spread zoonoses caused by hydrophilic bacteria of the genus Leptospira. Humans can be infected by contact with an infected animal or indirectly via staying in a contaminated environment (water, wet soil), in natural foci, while working outdoors, or while doing outdoor sport and leisure activities. Leptospirosis may manifest as a mild flu-like illness or in a severe febrile form (meningitis, pulmonary haemorrhage, hepato-renal syndrome, or myocarditis). Presented are the laboratory diagnostic methods for leptospiroses with their advantages and disadvantages...
