1/15. medical futility and the critically ill patient.Today, the world of critical care medicine has given us the capabilities to accomplish things that were only dreamed of a few decades ago. When combined with the increasing importance of patient autonomy and economics in healthcare, these new capabilities have caused conflicts about what is too little, and what is too much. medical futility becomes an issue whenever these conflicts arise. Understanding how to deal with issues surrounding futility begins with defining it. A firm definition is not possible or desirable, but revolves around the probability of being able to achieve a patient's goal with modern medicine. Establishing this understanding between the patient and their family (team), and the healthcare team, is dependent on trust between the two. It must be recognized that there are many reasons for families to not trust healthcare professionals and that these reasons need to be explored and dealt with. Sometimes conflicts regarding predictions and economics need to be addressed. Once trust is established a goal for a course of medical treatment should be discussed from the patient's perspective. This discussion should involve the physician's best judgement as to the chances of achieving this goal, and what type of discomfort or indignity, if any, the patient may experience. Only after these have been clearly discussed can decisions regarding medical futility be made. To date, the U. S. Courts have refused to grant physicians and hospitals the power to override the opinions of family members on matters of futility. However, with time, a consensus of public opinion should influence decisions regarding medical futility.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
2/15. Lethal late onset cblB methylmalonic aciduria.OBJECTIVE: To alert the physicians to the possibility of a late-onset inborn error of metabolism in an apparently previously healthy patient with acute clinical presentation. DESIGN: Case report. SETTING: Pediatric unit and general intensive care unit. PATIENT: An apparently previously healthy 12-yr-old female presented acutely with vomiting, fever, bronchopneumonia, and progressive loss of consciousness associated with ketoacidosis, hyperglycemia, and hyperammonemia. She died 3 days later with a diagnosis of insulin-dependent diabetes mellitus. INTERVENTIONS: Intravenous hydration, glucose and insulin, mechanical ventilation. MEASUREMENTS AND MAIN RESULTS: Organic acid analysis on a postmortem sample of aqueous humor revealed high levels of methylmalonic acid. Enzymatic studies on cultured fibroblasts were consistent with the diagnosis of cblB methylmalonic aciduria. CONCLUSIONS: The diagnosis of cblB methylmalonic aciduria was made in a postmortem patient who died with a misdiagnosis of insulin-dependent diabetes mellitus. Unclear biochemical findings and positive family history should strongly lead to suspicion of an inborn error of metabolism in an apparently previously healthy critically ill patient.- - - - - - - - - - ranking = 0.5keywords = physician (Clic here for more details about this article) |
3/15. peripheral arterial disease is only the tip of the atherosclerotic "iceberg".The peripheral vascular system makes up the largest single "organ system" and holds many biological secrets that, when unlocked, can open doors for new treatments for all vascular beds, including those of the coronary and cerebral arteries. The coronary and noncoronary circulations are inseparable and interdependent. Cardiologists as well as primary care physicians should have a global view in the management of patients with PAD. The treatment of atherosclerosis in any of the arterial beds is a multifactorial problem. PAD is underrecognized. Antiplatelet and lipid-lowering therapy is underutilized in patients with PAD. Clopidogrel, an antiplatelet drug, has proven to prevent adverse cardiovascular events in patients with PAD. Therapeutic angiogenesis has been reported to improve severe claudication.- - - - - - - - - - ranking = 0.5keywords = physician (Clic here for more details about this article) |

7/15. extracorporeal membrane oxygenation after stem cell transplant: clinical decision-making in the absence of evidence.OBJECTIVE: To discuss the ethical dilemmas that arise in considering innovative therapies for critically ill children when there is little data to support their use. DESIGN: Case report of a 13-yr-old patient after autologous peripheral blood stem cell transplant for stage III neuroblastoma with sepsis and hemodynamic instability who survived to discharge after a 6-day course of extracorporeal membrane oxygenation (ECMO) support. The case serves as a source of discussion of the following: the use of available data in deciding to proceed with an unproved therapy, the approach to conversations to obtain informed consent, and the need for institutional oversight and hypothesis-driven data collection to advance pediatric critical care. SETTING: Pediatric intensive care unit at a university hospital. Patient: One adolescent with stage III neuroblastoma. RESULTS: Despite a lack of data to support the use of ECMO in a neutropenic oncology patient after autologous peripheral blood stem cell transplant, our patient had clinical features that suggested he was a reasonable ECMO candidate. His family gave informed consent to use ECMO and he survived. It is ethical to consider and use innovative therapies when patient characteristics are suggestive that the therapy may be successful even in the absence of evidence. This requires physicians' attention to the best interest of the patient and should occur in the setting of informed consent and rigorous data collection. CONCLUSIONS: The boundaries among standard therapy, innovative therapy, and research can be quite fluid. This case illustrates the ethical imperative to consider therapies that may be appropriate for a critically ill child even without evidence predictive of success, to have entry criteria and treatment protocols for such therapies, and to collect data from such experiences to advance the standard of care.- - - - - - - - - - ranking = 0.5keywords = physician (Clic here for more details about this article) |
8/15. Hyperosmolar hyperglycemic crisis: an acute life-threatening event in children and adolescents with type 2 diabetes mellitus.OBJECTIVE: To discuss the initial clinical manifestations and management of 8 obese African American children and adolescents who presented with a severe hyper-osmolar hyperglycemic state (HHS) and were newly diagnosed with type 2 diabetes mellitus (DM), except for one who most likely had type 1 DM. methods: We summarize the clinical presentation, pertinent laboratory values, management, complications, outcome, and follow-up of 8 obese pediatric patients who had HHS and alteration of mental function. RESULTS: Seven male and one female African American patients from 11 to 17 years of age with a body mass index that exceeded the 97th percentile were treated for HHS. All patients had alteration of mental status, ranging from confusion to coma. Five patients had venous CO(2) levels <14 mEq/L. Corrected sodium in all patients was in the hypernatremic range in conjunction with high effective serum osmolality. After fluid replacement (the most important aspect of treatment), intravenous insulin therapy was initiated. Metabolic control was achieved in all patients within 36 hours after admission. Complete recovery ensued in all patients except one, who died on the sixth day of hospitalization, possibly attributable to massive pulmonary embolism. CONCLUSION: The incidence of obesity and type 2 DM in children and adolescents is increasing at an alarming rate. Many patients previously undiagnosed with type 2 DM may indeed present with HHS. Because experience and published literature regarding HHS in pediatric patients are meager, this is a new challenge for physicians. mortality and morbidity are high in this group of patients, and a high index of suspicion and awareness of this condition by physicians are warranted.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
9/15. medical futility in the neonatal intensive care unit: hope for a resolution.Contemporary medical practice in the NICU sometimes leads to conflicts between providers and parents in which the parent demands continuation of life-sustaining treatment that the medical team deems medically inappropriate or futile. Such conflicts can be difficult to resolve and trying for all parties. Here we describe a conflict involving a 25-week-gestation, 825-g newborn with multiple intractable medical problems and resolution of the conflict through ethics consultation under provisions of the texas advance directives Act. The process established under texas law sets conceptual and temporal boundaries around the problem of medical futility and provides a legal safe harbor for physicians who seek to withdraw life-sustaining treatments in the setting of medical futility, allowing resolution of such conflicts in a timely and effective manner. As such, it may provide a model for physicians in other states to follow.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
10/15. decision making in critically ill patients with hematologic malignancy.hematologic neoplasms that were previously considered fatal are now potentially curable with techniques such as bone marrow transplantation. Such therapies also carry significant morbidity and mortality. With the increasing application of these therapies, a growing number of physicians are using medical decision making regarding critical care for these patients. The process by which ethical decisions are reached for these critically ill patients may be baffling because of several factors: rapidly evolving treatments, uncertain probabilities of the cure of the malignant disorder, the relatively young age of many of these patients, and the poor prognosis with critical illness. I discuss a process to reach acceptable decisions, providing a case example of the application of the process. This process is derived from the ethical principles that drive decision making in general medicine and attempts to maximize patients' autonomy. It involves a consideration of accurate information regarding the disease process and the prognosis, a clear delineation of the goals of the medical care, and communication with patients. Appropriate, ethical, and consistent decisions regarding the critical care of patients with hematologic malignancy can be reached when these considerations are addressed.- - - - - - - - - - ranking = 0.5keywords = physician (Clic here for more details about this article) |
