Background Behçet's disease is an inflammatory condition, caused by vasculitis of big and small veins and arteries in which, although vascular inflammation is the basis of disease, cardiac involvement is rare. We present a rare case of a man, affected by Behçet's disease, with pulmonary embolism due to a floating thrombus in the right ventricle. Case summary We report a case of a 36-year-old man admitted to emergency department due to dyspnoea and haemoptysis. He had already been diagnosed with Behçet's disease, and he was in therapy with low doses of azathioprine and prednisone from three months. Thorax CT scan detected pulmonary embolism with pulmonary infraction. No evidence of deep vein thrombosis was found. The echocardiogram pointed out a floating mass of at least 30 mm in the right ventricle. Cardiac magnetic resonance confirmed the diagnosis of right ventricle thrombosis. On the hypothesis of an inflammatory genesis of the thrombosis, immunosuppressive drugs and anticoagulation with vitamin K antagonist were prescribed. The patient underwent echocardiograms every 3 weeks, and the mass disappeared 5 months later. Discussion Behçet's disease is a systemic inflammatory disorder that often affects vessels and rarely the heart. Thrombosis can be the only clinical feature of primary or relapsing events with also atypical origin site. Thrombosis suggests a high inflammatory status that needs to be balanced with the right immunosuppressive therapy, associated to anticoagulation. [ABSTRACT FROM AUTHOR]

Background: Low-grade incomplete post-dexamethasone cortisol suppression in patients with adrenal incidentalomas - recently defined as possible autonomous cortisol secretion (pACS) - has been associated with increased cardiovascular events and mortality. However, prospective studies documenting cardiac abnormalities in these patients are lacking. Subjects and methods: Between July 2016 and September 2017, 71 consecutive patients with adrenal lesions were prospectively screened for hypercortisolism by dexamethasone suppression test (NCT 02611258). Complete anthropometric, metabolic and hormonal parameters were recorded along with full cardiac ultrasound assessment and noninvasive measurement of arterial stiffness. All patients underwent chemical-shift magnetic resonance imaging to characterize the lesions. Cardiovascular outcomes were recorded in blind. Results: According to post-dexamethasone suppression cortisol values (post-DST), 34 patients had pACS and 37 nonfunctioning adenomas (NFA). The two groups were similar in sex, BMI, age distribution, cardiovascular risk factors and comorbidities. Left ventricular mass index (LVMIBSA) was increased in pACS compared to NFA (P = 0.006) and mildly correlated to the post-DST cortisol level (rho = 0.347; P = 0.004). The post-DST cortisol levels explained up to 13.7% of LVMIBSA variance (P = 0.002). Compared to NFA, patients with pACS had a higher prevalence of diastolic dysfunction (35.1% vs 82.6%; P = 0.001) and worse arterial stiffness assessed by pulse wave velocity (P = 0.033). Conclusions: In apparently asymptomatic patients, mild autonomous cortisol secretion can sustain early cardiac and vascular remodeling, independently of other risk factors. The morphological and functional cardiovascular changes observed in pACS underline the need for further studies to correctly define the long-term management of this relatively common condition.

Background Clostridioides difficile infection (CDI) might be complicated by the development of nosocomial bloodstream infection (n-BSI). Based on the hypothesis that alteration of the normal gut integrity is present during CDI, we evaluated markers of microbial translocation, inflammation, and intestinal damage in patients with CDI. Methods Patients with documented CDI were enrolled in the study. For each subject, plasma samples were collected at T0 and T1 (before and after CDI therapy, respectively), and the following markers were evaluated: lipopolysaccharide-binding protein (LPB), EndoCab IgM, interleukin-6, intestinal fatty acid binding protein (I-FABP). Samples from nonhospitalized healthy controls were also included. The study population was divided into BSI+/BSI- and fecal microbiota transplantation (FMT) +/FMT- groups, according to the development of n-BSI and the receipt of FMT, respectively. Results Overall, 45 subjects were included; 8 (17.7%) developed primary n-BSI. Markers of microbial translocation and intestinal damage significantly decreased between T0 and T1, however, without reaching values similar to controls (P <.0001). Compared with BSI-, a persistent high level of microbial translocation in the BSI+ group was observed. In the FMT+ group, markers of microbial translocation and inflammation at T1 tended to reach control values. Conclusions CDI is associated with high levels of microbial translocation, inflammation, and intestinal damage, which are still present at clinical resolution of CDI. The role of residual mucosal perturbation and persistence of intestinal cell damage in the development of n-BSI following CDI, as well as the possible effect of FMT in the restoration of mucosal integrity, should be further investigated.

Riassunto. Le dissecazioni delle arterie cervicali (DAC) sono una causa inusuale di ictus ma il loro tasso di prevalenza cresce fino al 20% nella fascia di età giovane-adulta. In molti casi le dissecazioni si associano a rare malattie connettivali come la sindrome di Ehlers-Danlos, di Marfan, la fibrodisplasia. I fattori di rischio esterni principali sono rappresentati da bruschi traumi cervicali come negli incidenti stradali o, meno frequentemente, da procedure meno cruente come la manipolazione e l'iperestensione prolungata del collo. Diversi casi di DAC sono presenti in letteratura dopo sedute chiropratiche, procedure odontoiatriche ed endoscopiche. Noi riportiamo un insolito caso di dissecazione della carotide interna di sinistra causata da iperestensione del collo occorsa dopo uno shampoo dal parrucchiere.

POEMS syndrome (P polyradiculoneuropathy, O organomegaly, E endocrinopathy, M clonal plasma cell disorder, and S skin changes) is a rare syndrome due to a plasma cell dyscrasia. It is characterized by polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, skin changes. Increased serum VEGF, sclerotic bone lesions, Castleman's disease, oedema, ascites, papilledema and thrombocytosis are other important clinical features. We report a case of POEMS syndrome in a 34-years old man with an unusual clinical presentation. Dyspnoea, organomegaly, and skin changes preceded the clinical manifestations of polyneuropathy. The variability of presentation of the POEMS should suggest to consider the diagnosis even in the lack of the signs of polyneuropathy.
