Despite many unanswered questions regarding the pathogenesis of interstitial lung disease in systemic sclerosis (SSc-ILD) and the lack of accurate epidemiological risk factors, there have been major advances in the identification and prognostic evaluation of SSc-ILD. The evaluation of disease severity is a multidisciplinary exercise, requiring the integration of pulmonary function tests, high-resolution computed tomography data, and symptomatic severity and these factors all need to be considered in the detection of disease progression. Except in a minority of patients with reversible inflammatory disease, the primary goal of treatment is the prevention of disease progression. ⋯ There is a need to broaden therapeutic approaches with the exploration of rituximab (based on recent pilot data) and antifibrotic agents, shown to have treatment effects in other fibrotic interstitial lung diseases. However, it is also important to avoid the overtreatment of SSc-ILD patients with limited nonprogressive lung involvement. In that setting, an initial policy of nonintervention but meticulous observation ("masterful inactivity with cat-like observation") is often warranted.

ReviewPulmonary manifestations of polymyositis/dermatomyositis.
The idiopathic inflammatory myopathies are a group of connective tissue diseases marked by varying degrees of muscle inflammation and clinical involvement of multiple organs, most notably, the lung. Pulmonary manifestations consist primarily of interstitial lung disease (ILD), which is associated with significant morbidity and mortality in myositis patients. Several myositis-specific antibodies have been discovered, as well as antibodies targeting various aminoacyl-tRNA synthetase enzymes. ⋯ Steroids remain the first-line treatment for myositis-associated ILD and the antisynthetase syndrome, though other traditional immunosuppressants have demonstrated efficacy in numerous studies. While a majority of patients experience either stabilization or improvement in lung imaging and function, fatal progression is still reported in a significant number of cases. Further research is needed to develop more effective and targeted therapies.

Whether Native American ancestry (NAA) is associated with COPD or lung function in a racially admixed Hispanic population is unknown. ⋯ NAA is inversely associated with COPD but positively associated with FEV1 or FVC in Costa Ricans. Ancestral effects on smoking behavior partly explain the findings for COPD but not for FEV1 or FVC.

Observational Study
Subarachnoid Extension of Primary Intracerebral Hemorrhage is Associated with Fevers.
Extension of hemorrhage into the subarachnoid space in primary intracerebral hemorrhage (ICH) has recently been associated with poor outcomes, although the mechanisms underlying that association are uncertain. The objectives of this study are to confirm the association between fever and poor outcomes after ICH, and to determine whether subarachnoid hemorrhage extension (SAHE) is associated with fevers. ⋯ Our data confirm the deleterious effect of fever on the outcome of patients with ICH and show that SAHE is an independent predictor of fever after ICH. SAHE may provoke dysfunctional thermoregulation similar to what is observed after aneurysmal subarachnoid hemorrhage, creating mechanistic pathway between SAHE and poor functional outcomes.

Review[Anaesthesiological management of patients with dementia].
The aging society challenges anaesthesiologists with a growing number of patients with dementia. These and their relatives worry about an aggravation of an already existing dementia or even the postoperative evocation of one. Common volatile anaesthetics and propofol are suspected to increase dementia - associated protein tau and amyloid-betalevels in the brain. ⋯ In dementia, perioperative malfunction of cognition, memory, attention, information processing, communication and social interaction abilities is of profound influence on the perioperative management. This review mentions actual knowledge about dementia forms and symptoms in brief. Recommendations for the anaesthesia care are given in more detail.
