Acute Respiratory Distress Syndrome (ARDS) is defined by bilateral diffuse infiltrates on chest radiography, a PO2/FiO2 ratio < 200, and noncardiogenic pulmonary edema. Pathophysiologically it is characterized by disruption of the alveolar lining and capillary endothelium, alveolar edema, protein exudation coupled with a marked inflammatory response and subsequent fibrosis and a resultant ventilation-perfusion mismatch. Effective treatment strategies include low tidal volume ventilation with positive end expiratory pressure, careful fluid management and good supportive care.

Empirical and clinical studies clearly demonstrate significant adverse effects of cannabis smoking on physical and mental health as well as its interference with social and occupational functioning. These negative data far outweigh a few documented benefits for a limited set of medical indications, for which safe and effective alternative treatments are readily available. If there is any medical role for cannabinoid drugs, it lies with chemically defined compounds, not with unprocessed cannabis plant. Legalization or medical use of smoked cannabis is likely to impose significant public health risks, including an increased risk of schizophrenia, psychosis, and other forms of substance use disorders.

Although uncommon, "brain cancer" is one of the most feared diseases that afflict human beings. While still regarded as one of the most deadly forms of primary malignant brain neoplasm, recent advances in the treatment of Glioblastoma Multiforme (GBM) have offered new hope for patients, families and clinicians. In the first part of this two-part evidence-based review, we focused on the multidisciplinary advances that have established the current standard of care practice in the management of GBM. The second part discusses ongoing research efforts, both ongoing clinical trial efforts as well as some of the newer technologies that are forming the promise of the future.

Non-traumatic subarachnoid hemorrhage (SAH) represents approximately 5-6% of all strokes. Morbidity and mortality rates remain high, but accurate diagnosis using clinical assessment and neuroimaging, critical care management, and early treatment using either surgical or interventional techniques have improved overall outcomes. This, the fifth in a Missouri Medicine series on stroke, summarizes the clinical and imaging aspects of making the diagnosis of SAH, critical care management of the patient, treatment options, and factors important in prognosis.
