BACKGROUND: Point-of-care ultrasonography (POCUS) is a widely used tool in emergency and critical care settings, useful in the decision-making process as well as in interventional guidance. While having an impressive diagnostic accuracy in the hands of highly skilled operators, inexperienced practitioners must be aware of some common misinterpretations that may lead to wrong decisions at the bedside. OBJECTIVES: This article provides a revision list of common POCUS misdiagnoses usually found in practice and offers useful tips to recognize and avoid them...

Objectives Diarrheal disease is a significant cause of morbidity among children in Peru. Oral rehydration therapy (ORT) is a cost-effective evidence-based approach to treat diarrhea in young children, yet many Peruvian children in poorer households do not receive this life-saving treatment. This study investigates the social determinants of care-seeking behavior and utilization of appropriate home treatment for diarrheal episodes. Methods We used the nationally-representative 2008 Peru Demographic and Health Survey to: (1) describe the burden of non-bloody diarrheal disease among children <5 years old; and (2) identify socioeconomic correlates of care-seeking behavior and utilization/appropriateness of treatment among mothers of children with recent non-bloody diarrheal episodes (N = 1365)...

UNLABELLED: Pathologic inclusions define α-synucleinopathies that include Parkinson's disease (PD). The most common genetic cause of PD is the G2019S LRRK2 mutation that upregulates LRRK2 kinase activity. However, the interaction between α-synuclein, LRRK2, and the formation of α-synuclein inclusions remains unclear. Here, we show that G2019S-LRRK2 expression, in both cultured neurons and dopaminergic neurons in the rat substantia nigra pars compact, increases the recruitment of endogenous α-synuclein into inclusions in response to α-synuclein fibril exposure...

CONTEXT: Lung transplantation is limited by donor lung availability with ∼20% of deceased donor lungs transplanted. Diagnostic testing identifying pulmonary derangements guide donor management strategies to maximize lung transplantation. Lung ultrasound (LUS) identifies pathology in critically ill patients equivalent or superior to chest radiograph (CXR) or computed tomography (CT) scans. No published studies have reported on LUS in neurologically deceased donors (DNDDs). OBJECTIVE: We evaluated LUS in identifying abnormal lung pathology in DNDDs and related these findings to the standard approach...

BACKGROUND: The analysis of lung artefacts has gained increasing importance as markers of lung pathology. B-line artefact (BLA), caused by a reverberation phenomenon, is the most important lung artefact. In this review, we discuss the current role of BLA in pneumology and explore open questions of the published consensus. METHODS: We summarized current literature about BLA. Also, we presented observations on healthy subjects and patients with interstitial syndrome (pulmonary fibrosis and edema), to investigate technical factors influencing BLA visualization...

Selective splenic artery embolization (SSAE) is a nonsurgical intervention characterized by the transcatheter occlusion of the splenic artery and/or its branch vessels using metallic coils or other embolic devices. It has been applied for the management of splenic trauma, hypersplenism with portal hypertension, hereditary spherocytosis, thalassemia and splenic hemangioma. We hereby describe a case of a patient affected by idiopathic thrombocytopenic purpura (ITP) and warm auto-immune hemolytic anemia (AIHA) both resistant to immunosuppressive and biological therapies, not eligible for a surgical intervention because of her critical conditions...

Animal models of Parkinson's disease (PD) are important for understanding the mechanisms of the disease and can contribute to developing and validating novel therapeutics. Ideally, these models should replicate the cardinal features of PD, such as progressive neurodegeneration of catecholaminergic neurons and motor defects. Many current PD models emphasize pathological forms of α-synuclein, based on findings that autosomal dominant mutations in α-synuclein and duplications/triplications of the SNCA gene cause PD...

PURPOSE: On a regular basis, the intensivist encounters the patient who is difficult to wean from mechanical ventilatory support. The causes for failure to wean from mechanical ventilatory support are often multifactorial and involve a complex interplay between cardiac and pulmonary dysfunction. A potential application of point of care ultrasonography relates to its utility in the process of weaning the patient from mechanical ventilatory support. METHODS: This article reviews some applications of ultrasonography that may be relevant to the process of weaning from mechanical ventilatory support...

Increasing evidence points to inflammation as a chief mediator of Parkinson's disease (PD), a progressive neurodegenerative disorder characterized by loss of dopamine neurons in the substantia nigra pars compacta (SNpc) and widespread aggregates of the protein α-synuclein (α-syn). Recently, microRNAs, small, noncoding RNAs involved in regulating gene expression at the posttranscriptional level, have been recognized as important regulators of the inflammatory environment. Using an array approach, we found significant upregulation of microRNA-155 (miR-155) in an in vivo model of PD produced by adeno-associated-virus-mediated expression of α-syn...

BACKGROUND: Chest tube positioning is an invasive procedure associated with potentially serious injuries. In the last few years, we have been running a project directed at developing a practical simulator of a surgical procedure taught on our medical training program. The phantom model reconstructs the pleural anatomy, visible by lung ultrasound, used for the assessed performance of the Seldinger technique. The aim of the present study was to investigate the validity of this simulation technology for assessing residents in anesthesia and intensive care medicine; specifically, their skill in positioning a US-guided chest tube drain was tested using the simulator device...

Trophic factors show great promise in laboratory studies as potential therapies for PD. However, multiple double-blind, clinical trials have failed to show benefits in comparison to a placebo control. This article will review the scientific rationale for testing trophic factors in PD, the results of the different clinical trials that have been performed to date, and the possible explanations for these failed outcomes. We will also consider future directions and the likelihood that trophic factors will become a viable therapy for patients with PD...

Both Dasision and ENESTnd trials had many exclusion criteria, with a possible selection bias compared with the real-life. To address the impact of this bias on the first-line treatment in the current clinical practice, we revised 207 unselected newly diagnosed chronic phase chronic myeloid leukaemia (CML) patients [M/F 108/99, median age 58.8 years, interquartile range 42.3-70.2] treated with front-line imatinib from June 2002 to June 2013 at our Institution, and evaluated how many of them would have been excluded from enrolment in the two trials...

BACKGROUND: We evaluated the use of TachoSil(®) for anchoring middle lobe to lower lobe after upper right lobectomy. METHODS: The fixation of middle lobe to lower lobe was required in 39/213 consecutive upper lobectomies. In 19/39 (49%) cases, it was performed with suturing and/or stapler (standard group) and in 20 cases (TachoSil group) with Tachosil(®) alone. RESULTS: The operative time, complications, length of chest drain and hospital stay were similar between two groups...

Respiratory complications are common causes of morbidity and the need of repeated X-ray examinations after cardiac surgery. Ultrasound of the chest, including the lung parenchyma, has been recently introduced as a new tool to detect many pulmonary abnormalities. Despite this, the use of lung ultrasound (LUS) in adult and congenital cardiac surgery remains limited. In particular, lung ultrasound has been mainly used in the evaluation of pleural effusion (PLE), but no consensus exists on methods to quantify the volume of the effusion...

We recently identified Smads1, 5 and 8 as muscle biomarkers in human ALS. In the ALS mouse, these markers are elevated and track disease progression. Smads are signal transducers and become activated upon receptor engagement of ligands from the TGF-β superfamily. Here, we sought to characterize ligands linked to activation of Smads in ALS muscle and their role as biomarkers of disease progression. RNA sequencing data of ALS muscle samples were mined for TGF-β superfamily ligands. Candidate targets were validated by qRT-PCR in a large cohort of human ALS muscle biopsy samples and in the G93A SOD1 mouse...
