TUS imaging of pleural/subpleural structures can detect ultrasonographic signs of initial PF prior to the onset of respiratory symptoms and function test abnormalities and, together with current criteria, could thereby enable exclusion of PF in SSc patients. Indicating some patients for selective referral to HRCT can thereby delay unwarranted procedures, provided that pulmonary function and TUS images are stable.
Two young male patients with severe progressive Behcet's disease with neurological involvement (N-BD) were treated by high-dose immunosuppressive chemotherapy (HIC) followed by autologous CD34+ selected peripheral blood stem cell transplantation (APBSCT). Neurological impairment and disability were quantified by means of Expanded Disability Status Scale (EDSS). Neuroimaging included spine and brain MRI and brain SPECT by radiolabeling technetium (Tc99m) Ethyl Cisteynate Dimer (ECD). Disease progression halted after treatment in both patients. At 48 months of follow-up they were therapy-free and one showed neurological status and disability improvement. Brain MRI findings were unchanged in both patients, but SPECT-ECD showed an increase of blood flow in the hypoperfused cerebral areas in the ameliorated patient. Immune ablation followed by APBSCT can modify the course of severe N-BD. Because of the high risk and the transplant-related mortality, these cases have to be carefully selected.
The treatment with iloprost plus bosentan is effective in determining healing of DUs in SSc patients with mild digital skin fibrosis. Conversely, the severity of skin fibrosis strongly influences the healing process of DUs. The study confirmed the efficacy of bosentan to prevent onset of new DUs.
The term pulmonary arterial hypertension (PAH) identifies a heterogeneous group of diseases characterized by a progressive increase in pulmonary arterial resistance (PVR), which causes a significant burden in terms of quality of life, right heart failure and premature death. The pathogenesis of PAH is not completely clear: the remodeling of the small pulmonary vessels is crucial, causing an increase in the resistance of the pulmonary circle. Its diagnosis is based on cardiac catheterization of the right heart. According to the present hemodynamic definition of pulmonary hypertension (PH) proposed by the Guidelines of the European Society of Cardiology/European Respiratory Society (ESC-ERS), the mean pulmonary arterial pressure (mPAP) values are ≥25 mmHg. In case of PAH, apart from an mPAP value ≥25 mmHg, patients must have a >3 Wood units increase in PVR and normal pressure values of the left heart. PH is a pathophysiological condition observed in more than 40 different diseases, while PAH is a primary disease of the pulmonary bloodstream potentially treatable with specific drugs. PAH is a severe complication of systemic sclerosis (SSc) affecting about 10% of the patients. Due to the devastating nature of SSc-PAH, there is a clear need to systematically adopt appropriate screening programs. In fact, despite awareness of the negative impact of SSc-PAH on quality of life and survival, as well as on the severity of lung function, at the moment standardized and shared guidelines and/or screening programs for the diagnosis and the subsequent early treatment of PAH in SSc are not available. The aim of the present paper is to highlight the lights and shadows of SSc-PAH, unraveling the unmet clinical needs on this topic with a proposal of clinical-diagnostic and therapeutic guidelines.
In the last years, transthoracic ultrasound (TUS) has regained a growing interest from both clinicians and radiologists as a useful and non-invasive diagnostic tool for the study of many pleuro-pulmonary conditions, including interstitial lung diseases. Intraoperative lung ultrasound (ILU) is an ultrasound technique, developed for lung surface assessment during video-assisted thoracoscopic surgery procedures. It has been developed considering ultrasound basic physics principles for images generation and interpretation. Most of the TUS findings are due to the high difference in acoustic impedance between the chest-wall structures and the air in the lungs. In this brief communication, we compared ILU and TUS images in interstitial lung diseases. Most of the TUS artifacts-based diagnostic algorithms should be reappraised.
The group of diseases classified as seronegative spondyloarthritis or enthesoarthritis is characterized by typical osteoarticular and extra-articular manifestations. Diverse patterns of disease can affect different members of the same family and may show different features in the same patient, with clinical overlaps thwarting the differential diagnosis. An anatomo-pathological hallmark in enthesoarthritis is the inflammatory process in the synovio-entheseal sites. The inflammatory microenvironment of synovio-entheseal complex, named enthesitis, is characterized, after an initial inflammatory/erosive phase, by a subsequent phase of neobone apposition, which seems to progress independently from the previous erosive phase, suggesting that the physiopathogenetic mechanisms that underlay the two phases are driven by different pivots. The structural damage is characterized by excessive neobone formation, with the syndesmophyte as a typical lesion. The process underlying their formation is not fully understood, although there are many useful information to clarify the physiopathogenetic puzzle. The primum movens of the enthesitic process is the micro-trauma to which entheses are subject, especially in the lower limbs, for biomechanical reasons. The inflammatory process is facilitated by the sequential structure of the organ enthesis, constitutionally devoid of sub-enthesitic cortical bone and closely related to the underlying trabecular bone and the medullary vascular system. The reparative attempt from the vascular system, thanks to the activating action of certain loco-regional cytokines, such as TNF α, conditions the possible deposit in the enthesis of molecules derived from other organic sites and able, especially in HLA-B27+ subjects, to activate and self-renew an immune-mediated inflammatory process following the initial mechanical process.
Psoriasis is a complex disease often needing a multidisciplinary approach. In particular, the collaboration between dermatologist and rheumatologist is crucial for the management of patients suffering from both psoriasis (PSO) and psoriatic arthritis (PsA). Here we report a series of recommendations from a group of experts, as a result of a Consensus Conference, defining the circumstances in which it is preferable or even mandatory, depending on the available settings, to rely on the opinion of the two specialists, jointly or in a deferred manner. Indications are given on how to organize a 3rd level joint Dermatology- Rheumatology care unit, in connection with 1st and 2nd level clinicians of both specialties, GPs, and other specialists involved in the management of psoriasis. A potential patient journey is suggested, that can be used as a basis for future design and validation of national and/or local diagnostic therapeutic and assistance pathways.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
