A 48-year-old woman suffering from Takayasu arteritis presented with middle aortic syndrome consisting of abdominal pain, refractory hypertension with pulmonary edema and pleural effusions, and lower limb ischemia. She failed to improve with high-dose steroid therapy and underwent endovascular stenting of two severe stenoses in the supraceliac and infrarenal aorta. Her symptoms resolved and hypertension improved after the procedure.

Acute lung injury (ALI) models are characterized by neutrophil accumulation, tissue damage, alteration of the alveolar capillary membrane, and physiological dysfunction. Lipoxin A4  (LXA4 ) is an anti-inflammatory eicosanoid that was demonstrated to attenuate lipopolysaccharide-induced ALI. Experimental models of severe malaria can be associated with lung injury. However, to date, a putative effect of LXA4  on malaria (M)-induced ALI has not been addressed. In this study, we evaluated whether LXA4 exerts an effect on M-ALI...

Here, we tested the hypothesis that severe pulmonary arterial hypertension impairs retrograde perfusion. To test this hypothesis, pulmonary arterial hypertension was induced in Fischer rats using a single injection of Sugen 5416 followed by 3 weeks of exposure to 10% hypoxia and then 2 weeks of normoxia. This Sugen 5416 and hypoxia regimen caused severe pulmonary arterial hypertension, with a Fulton Index of 0.73+0.07, reductions in both the pulmonary arterial acceleration time and pulmonary arterial acceleration to pulmonary arterial ejection times ratio, and extensive medial hypertrophy and occlusive neointimal lesions...

Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) provides mechanical circulatory support for patients with advanced cardiogenic shock, facilitating myocardial recovery and limiting multi-organ failure. In patients with severely limited left ventricular ejection, peripheral VA-ECMO can further increase left ventricular and left atrial pressures (LAP). Failure to decompress the left heart under these circumstances can result in pulmonary edema and upper body hypoxemia, that is, myocardial and cerebral ischemia...

Takotsubo syndrome is rare in pediatric patients but must be considered in patients with subarachnoid hemorrhage with pulmonary edema and cardiomyopathy. A systematic, collaborative approach is needed to facilitate emergent transfer of patients where extracorporeal cardiopulmonary resuscitation (e-CPR) is used as a lifesaving measure. Extracorporeal membrane oxygenation (ECMO) use in transport requires preplanning, role delineation, resources, and research efforts to be successful. We present an unusual transport case of successful e-CPR/ECMO treatment of Takotsubo syndrome in a 12-year-old boy with an isolated traumatic intracranial injury, cardiomyopathy with pulmonary edema, and multiple cardiac arrests...

Heart failure (HF) is a common health problem worldwide, including in Japan. Unfortunately, patient outcomes remain poor, with a 5-year survival rate of approximately 50%. Therefore, we need to assess the precise conditions, including cardiac function, in patients with HF, particularly in the elderly. We performed a multifaceted assessment in an elderly patient with HF on admission and at discharge using eight different evaluations (the mean life expectancy using the Seattle Heart Failure Model (SHFM), the severity of dementia, nutrition, medication adherence, biomarker (the level of brain natriuretic peptide in blood), sociality, performance and comorbidity)...

RATIONAL: Takotsubo cardiomyopathy (TCM) is a transient systolic dysfunction of the left ventricular apex without stenosis of coronary arteries and is induced by various psychological and physical factors. TCM sometimes causes lethal complications such as arrhythmia, thrombogenesis, and even cardiac rupture, and thus it should be diagnosed appropriately and managed carefully. Intensive care unit (ICU) patients are exposed to overstress during the treatment process and therefore can are at potential risk for TCM...

BACKGROUND Mesenteric panniculitis (MP) is an idiopathic chronic inflammatory condition of the mesentery. The main symptoms include abdominal pain, abdominal distention, weight loss, fever, nausea, and vomiting. The patients also present with chylous ascites in 14% of the cases and chylous pleural effusion (CPE) in very rare occasions. Despite the previous view of excellent prognosis of MP, two recent papers reported several fatal cases. However, there are still only a few autopsy case reports that describe the macroscopic and histological details of MP cases...

It is well known that vitamin E and selenium deficiencies in domestic ruminants can lead to white muscle disease. After a clinically normal gestation period at Ouwehand Zoo in the Netherlands, a newborn giraffe ( Giraffa camelopardalis) calf showed clinical signs of white muscle disease almost immediately after birth. The calf was rejected by the mother and was euthanized 3 days later because of deterioration of clinical signs. At necropsy, pulmonary edema and pallor of skeletal and heart muscles was noted...

Measurement of dynamic lung compliance during breathing requires measurement of esophageal pressure, whereas static respiratory system compliance (Crs) method requires several airway occlusions. Despite their precision these compliance methods are cumbersome and not suitable for evaluation of pulmonary system in intensive care. The current ventilators display dynamic Crs, which, however, is seldom utilized in clinical practice. We studied the feasibility of ventilator-derived dynamic Crs measurement in pulmonary evaluation after congenital cardiac surgery in children...

BACKGROUND: Assessments of maternal near miss (MNM) are increasingly used in addition to those of maternal mortality measures. The World Health Organization (WHO) has introduced an MNM tool in 2009, but this tool was previously found to be of limited applicability in several low-resource settings. The aim of this study was to identify adaptations to enhance applicability of the WHO MNM tool in sub-Saharan Africa. METHODS: Using a Delphi consensus methodology, existing MNM tools were rated for applicability in sub-Saharan Africa over a series of three rounds...

BACKGROUND: Enterovirus (EV) infection has been a serious health issue in Asia-Pacific region. It has been indicated that the occurrence of fatal hand foot and mouth disease (HFMD) cases following EV71 infection is mainly attributed to pulmonary edema. However, the development of pulmonary disorders after EV71 infection remains largely unknown. To establish an EV71-infected animal model and further explore the underlying association of central nervous system (CNS) invasion with pulmonary edema, we isolated a clinical source EV71 strain (ZZ1350) from a severe case in Henan Province...
