RESUMO
How do health care consumers, private sector organizations, professionals, and government agencies work toward ensuring quality end-of-life care? This challenge is by no means uniquely Canadian; our approach may thus have applications that extend well beyond our national borders. Raising the profile of palliative care in Canada has occurred on many fronts. Local, provincial, and national efforts in end-of-life care have long been underway. The Canadian Palliative Care Association has been particularly active, recently organizing various stakeholder groups to develop a strong national advocacy partnership for quality end-of-life care. Perhaps most distinctive has been the involvement and nationwide visibility of Canada's Senate. Their report, Quality End-of-Life Care: The Right of Every Canadian has seen Canadian palliative care gain unprecedented momentum. The federal government recently took the unprecedented step of creating a new office to represent palliative care within the federal cabinet. In Canada, it would appear that palliative care is an idea whose time has come.

A U.S. Marine Corps Reconnaissance diver suffered arterial gas embolism (AGE) while using a closed-circuit oxygen rebreathing scuba apparatus; there are few, if any, reported occurrences of AGE due to gases other than air. The high oxygen fraction of the diver's inspired gas may have contributed to his rapid recovery once recompression therapy was initiated.

BACKGROUND: The contribution of ethanol ([EtOH]) to the osmol gap (OG) is commonly described by the formula [EtOH (mg/dL)]/k, where k is assumed to be 4.6 (one-tenth of its molecular weight) if ethanol behaves ideally in solution. However, several studies on convenience samples of patients suggest that ethanol does not behave ideally and that k may be significantly different from this ideal constant. OBJECTIVES: To determine prospectively the relationship between serum ethanol concentration and total serum osmolality in a group of healthy volunteers. METHODS: Experimental subjects ingested 20 mL of 100% ethanol diluted in sugar-free soda at a rate of one drink every 10 min, up to a maximum of seven drinks. Control subjects ingested 20 mL of water diluted in sugar-free soda at the same rate. Blood samples were obtained at baseline and then at every 20 min for 180 min to measure serum [EtOH] concentration, electrolytes, glucose, and osmolality (via freezing-point depression). The OG was calculated by subtracting predicted osmolality from measured osmolality. The OG was then divided by [EtOH] to determine the coefficient of ethanol's contribution to total serum osmolality. RESULTS: A total of 10 volunteers (five men and five women; mean age, 38.8 years, and range, 28-49 years) participated in and completed the study. Eight (four male and four female) were in the experimental group, and two (one male and one female) were in the control group. Mean peak [EtOH] was 229 mg/dL (median, 223.5 mg/dL; IQR, 171-273 mg/dL) and a linear relationship between [EtOH] and OG (Pearson coefficient of 0.98) was found. Using covariate correction for each subject's baseline OG, k was calculated to be 4.25 (95% CI, 4.13-4.38) averaged over all participants. CONCLUSIONS: In this volunteer study, the coefficient describing the contribution of ethanol to serum osmolality (k) was found to be 4.25. This indicates that ethanol contributes more to total serum osmolality than would be predicted for an ideal solute.

GOALS OF WORK: Radiotherapy (RT) for palliation of pain due to bone metastases (BM) is effective but underutilized likely due to the traditional practice of separate clinic visits for consultation, treatment planning, and RT delivery. However, recent evidence proves one RT treatment is as effective as multiple for analgesia, enabling investigation of an alternative model of RT delivery, the rapid access palliative radiotherapy program (RAPRP). MATERIALS AND METHODS: Prior to the start of the program, needs assessment was performed to determine the composition of the optimal team. Screening tools were implemented to streamline holistic, multidisciplinary assessment. An advertising strategy, treatment and research protocols, and mechanisms for patient feedback were established. After RAPRP implementation, patient outcomes such as symptom relief were tracked. MAIN RESULTS: Eighty-six patients with painful BM were referred over the 25-week pilot. Median age was 69.9 years; 64% had prostate cancer, and median performance status was 70. Patient-rated pain was on average 6.1/10 at baseline, improving to 2.6/10 by week 4 post-RT. On average, 6.2 symptoms were reported (baseline) compared to 5.2 (week 4). Team members assessed 10-100% of patients and were successful in stabilizing or improving all symptoms in >75% contacted at week 4. One hundred percent of patients surveyed were satisfied with their experience. CONCLUSIONS: Early needs assessment was advantageous in determining the optimal team and methods of assessment for our 'one-stop' BM clinic. This approach was successful in improving pain and other symptoms, and the convenience of seeing multiple providers on 1 day was appreciated by the patients.

This review of the radiology of sarcoidosis encompasses intrathoracic involvement, upper respiratory tract sarcoidosis, pleural disease, and involvement of bone, joint, neurological system, heart, kidney and alimentary tract. Attention is drawn to the value of CT scans, magnetic resonance imaging, gallium, and neutron activation analysis.
