Comparison of Sense of Humor and Burnout in Surgeons and Internal Medicine Physicians.

OBJECTIVES: We aimed to evaluate humor styles in surgeons and internists and investigate the association between humor and burnout. METHODS: A cross-sectional survey of physicians in surgical and medicine departments was conducted, assessing sense of humor and burnout using the Humor Styles Questionnaire and the Emotional Exhaustion subscale of the Maslach Burnout Inventory-Human Services Survey for Medical Personnel. RESULTS: For 131 surgeons and 72 internists, no differences in humor styles were found. A sense of personal accomplishment was more common among surgeons (P = 0.03) and rates of burnout were lower for surgeons (P = 0.02). Physicians with a higher-than-average score in affiliative and self-enhancing humor were less likely to suffer from burnout (P < 0.0001 and P = 0.03, respectively). CONCLUSIONS: Surgeons and internists have similar styles of humor. Surgeons suffer less from burnout. Affiliative and self-enhancing humor styles are associated with reduced burnout.

Lysyl oxidase-a possible role in systemic sclerosis-associated pulmonary hypertension: a multicentre study.

OBJECTIVE: Lysyl oxidase (LOX) is an extracellular enzyme that cross-links collagen fibrils. LOX was found to be increased in serum of SSc patients and was suggested to be related to skin fibrosis, yet a vascular source of LOX has been demonstrated in idiopathic pulmonary arterial hypertension (iPAH). We aimed to validate elevated LOX serum levels in SSc and to study its correlation with clinical characteristics and investigate its main source at the tissue level. METHODS: A total of 86 established SSc patients were compared with 86 patients with very early diagnosis of systemic sclerosis (VEDOSS), 110 patients with primary RP (PRP) and 80 healthy controls. LOX serum levels were determined by ELISA. Five lung and 12 skin biopsies from SSc patients were stained for LOX and compared with controls. RESULTS: Serum levels of LOX in SSc were significantly higher than in VEDOSS, PRP and healthy controls (P < 0.001). LOX inversely correlated with the diffusing capacity of the lung for carbon monoxide diffusing capacity (DLCO) in diffuse SSc (r = -0.376, P = 0.02). Patients with moderate to severe estimated systolic PAH had higher LOX levels (P < 0.01). Lung biopsies demonstrated intense LOX staining in SSc patients with PAH that was predominantly located in the endothelium of the remodelled pulmonary vessels. CONCLUSION: Serum LOX levels are increased in established SSc and inversely correlate with the DLCO. LOX is elevated in patients with moderate to severe PAH and is located in the proliferating endothelium in lung arterioles, suggesting a possible role for LOX in SSc-associated PAH.

Radionuclide Methods in the Diagnosis of Sacroiliitis in Patients with Spondyloarthritis: An Update.

Sacroiliitis, inflammation of the sacroiliac joint (SIJ), is the hallmark of ankylosing spondylitis and spondyloarthritis (SpA) in general. The arsenal of recommended diagnostic modalities for imaging of the SIJ is scanty and, in practice, includes only conventional X-rays and magnetic resonance imaging (MRI). This review suggests that bone scintigraphy, particularly single-photon emission computed tomography (SPECT) with calculation of indices, or SPECT in combination with low-dose computed tomography (CT) can be a sensitive and specific tool for the diagnosis of sacroiliitis and can be used as part of the individualized approach to the diagnosis of axial SpA. In addition, [18F]fluoride positron emission tomography (PET)/CT imaging and immunoscintigraphy, using labeled monoclonal anti-cytokine antibodies, are promising methods of current scientific interest in this field.

Autoinflammatory associated vasculitis.

Autoinflammatory diseases are characterized by recurrent episodes of fever and localized or systemic inflammation and are caused by monogenic defects of innate immunity. The skin is commonly involved with various manifestations including erysipelas like rash and urticaria. Although vasculitis has been described in many autoinflammatory diseases, it has not been recognized as a characteristic feature of these diseases and autoinflammatory diseases are not listed as an etiology for vasculitis associated with a systemic disease in the 2012 Revised International Chapel Hill Consensus Conference Nomenclature of Vasculitides. We describe herein 3 patients with different autoinflammatory diseases in whom leukocytoclastic vasculitis was one of the major and presenting symptoms. A review of the vast evidence in the literature for vasculitis in the spectrum of autoinflammatory diseases and a suggested pathophysiology is presented. We suggest the term autoinflammatory associated vasculitis to describe vasculitis associated with autoinflammatory diseases. Autoinflammatory diseases should be considered within the differential diagnosis of vasculitis.
