The Complex Role of Gut Microbiota in Systemic Lupus Erythematosus and Lupus Nephritis: From Pathogenetic Factor to Therapeutic Target.

The role of gut microbiota (GM) and intestinal dysbiosis in triggering the onset and/or modulating the severity and progression of lupus nephritis (LN) has been the object of intense research over the last few years. Some alterations at the phyla level, such as the abundance of Proteobacteria and reduction in Firmicutes/Bacteroidetes (F/B) ratio and in α-diversity have been consistently reported in systemic lupus erythematosus (SLE), whereas a more specific role has been ascribed to some species ( and ) in LN. Underlying mechanisms include microbial translocation through a "leaky gut" and subsequent molecular mimicry, immune dysregulation (alteration of IFNγ levels and of balance between Treg and Th17 subsets), and epigenetic interactions.

Different patterns of neurogenic quadrilateral space syndrome: a case series of undefined posterior shoulder pain.

Background: Quadrilateral space syndrome is a painful disorder of the shoulder caused by static or dynamic entrapment of the axillary nerve and the posterior humeral circumflex artery. It was first described in 1983; however, it is an uncommon syndrome that initially presents with nonspecific shoulder pain or selective deltoid atrophy, and diagnosis is often delayed owing to its rarity. Young athletes of overhead sports are more commonly affected by this syndrome.

Analysis of shoulder motion with inertial sensors in Poland syndrome patients.

Purpose: Poland syndrome is a congenital malformation characterized by agenesis or hypoplasia of pectoralis muscles. There is a limited literature on how the anatomic anomalies of PS may impact the movement of the shoulder. This study analyzes the effects of absence of the pectoralis muscles on the shoulder kinematic.

Delayed diagnosis in Hirschsprung disease.

Introduction: Diagnostic delay in Hirschsprung disease is uncommon. Different definitions have been proposed but that of a diagnosis achieved after 12 months of age seems to be the most reliable and resorted to. Some authors reported a worse outcome in case of delay.

Instability Severity Index Score Does Not Predict the Risk of Shoulder Dislocation after a First Episode Treated Conservatively.

The first purpose of this study was to verify the association between Instability Severity Index Score (ISIS) and Recurrent Shoulder Dislocation (RSD) after a first episode treated conservatively. The second aim is to identify the risk factors associated with RSD after a primary acute shoulder anterior dislocation treated conservatively. A total of 111 patients with first traumatic anterior shoulder dislocation treated at a single trauma centre between January 2014 and March 2016 were enrolled.
