Migraine is a common headache disorder characterized by often-severe headaches that may be preceded or accompanied by a variety of visual symptoms. Although a typical migraine aura is not difficult to diagnose, patients with migraine may report several other visual symptoms, such as prolonged or otherwise atypical auras, "visual blurring", "retinal migraine", "ophthalmoplegic migraine", photophobia, palinopsia, and "visual snow". Here, we provide a short overview of these symptoms and what is known about the relationship with migraine pathophysiology. For some symptoms, the association with migraine is still debated; for other symptoms, recent studies indicate that migraine mechanisms play a role.

Randomized Controlled Trial Pragmatic Clinical Trial
Protocol for the electroencephalography guidance of anesthesia to alleviate geriatric syndromes (ENGAGES-Canada) study: A pragmatic, randomized clinical trial.
Background: There is some evidence that electroencephalography guidance of general anesthesia can decrease postoperative delirium after non-cardiac surgery. There is limited evidence in this regard for cardiac surgery. A suppressed electroencephalogram pattern, occurring with deep anesthesia, is associated with increased incidence of postoperative delirium (POD) and death. However, it is not yet clear whether this electroencephalographic pattern reflects an underlying vulnerability associated with increased incidence of delirium and mortality, or whether it is a modifiable risk factor for these adverse outcomes. Methods: The Electroe ncephalography Guidance of Anesthesia to Alleviate Geriatric Syndromes ( ENGAGES-Canada) is an ongoing pragmatic 1200 patient trial at four Canadian sites. The study compares the effect of two anesthetic management approaches on the incidence of POD after cardiac surgery. One approach is based on current standard anesthetic practice and the other on electroencephalography guidance to reduce POD. ⋯ Discussion: The ENGAGES-Canada trial will help to clarify whether or not using the electroencephalogram to guide anesthetic administration during cardiac surgery decreases the incidence, severity, and duration of POD. Registration: ClinicalTrials.gov ( NCT02692300) 26/02/2016.

Nontuberculous mycobacteria (NTM) are members of the Mycobacterium genus other than Mycobacterium tuberculosis complex and Mycobacterium leprae. NTM are widely distributed in the environment and are increasingly recognized as causes of chronic lung disease that can be challenging to treat. In this brief review, we consider recent developments in the ecology, epidemiology, natural history, and treatment of NTM lung disease with a focus on Mycobacterium avium complex (MAC) and Mycobacterium abscessus complex .

Background: The practice of continuous EEG monitoring (CEEG) in the intensive care unit (ICU) has spread over the past decade. Building an effective ICU CEEG program demands adequate EEG equipment and human resources. This may not be available in developing healthcare systems. ⋯ ICU CEEG was found to be effective in detecting potentially harmful subclinical patterns, supporting the need to develop ICU CEEG programs. However, the incurred excesses in morbidity and mortality associated with CEEG patterns were relatively modest. Further studies are needed to delineate how the practice of CEEG may be developed in similar healthcare systems to provide meaningful data to clinicians with regards to patient outcomes.

Background: Infectious diseases are common problems in mass gatherings, especially when there is a lack of health system preparedness. Since Iran is one of the most important countries on the walking path of Arbaeen and has a vital role in providing health services to pilgrims, the experiences of health challenges by participants is of key importance. The aim of this study is to explore stakeholders' experiences on the health system's preparedness and challenges, and to provide suggestions for preventing infectious diseases during the Arbaeen mass gathering. ⋯ Results: Data analysis resulted in the extraction of four main themes and 11 sub-themes. Health infrastructure defects in Iraq has three sub-themes (health abandonment in Iraq, the weaknesses in health culture and problems related to the health system); poor control of the causative factors of infectious diseases has three sub-themes (the underlying factors of the prevalence of contagious diseases, health system response to communicable diseases and ignoring the risks of the Arbaeen ceremony); the low perception of risk in pilgrims has three sub-themes (lack of awareness in pilgrims, fatalism in pilgrims and unhygienic belief in pilgrims); and the ineffectiveness of health education has two sub-themes (training shortage in the targeted group and educational content problems) that shows participant's experiences of the health system's challenges for coping with infectious diseases during the Arbaeen ceremony. Conclusion: Pilgrim-based training, planning and controlling other challenges may change these threats to opportunities and improve the health of participants of the mass gathering of Arbaeen in the region.
