Endoscopic CO2 laser excision of large or recurrent laryngeal saccular cysts in adults

BACKGROUND: Most paediatric cardiac arrest studies have been conducted in the USA, where paramedics provide prehospital emergency care. We wanted to study the outcome of paediatric cardiac arrest patients in an emergency medical system which is based on physician staffed emergency care units. METHODS: We analysed retrospectively the files of 100 prehospital cardiac arrest patients from Southern Finland during a 10-year study period. The patients were less than 16 years of age. RESULTS: Fifty patients were declared dead on the scene (DOS) without attempted resuscitation, and cardiopulmonary resuscitation (CPR) was initiated in 50 patients. The sudden infant death syndrome was the most common cause of arrest in the DOS patients (68%) as well as in those receiving CPR (36%). Asystole was the initial cardiac rhythm in 70% of the patients in whom CPR was attempted. Resuscitation was successful in 13 patients, 8 of whom were ultimately discharged. Six of the patients survived with mild or no disability and 4 of them had near-drowning aetiology. In multivariate analysis, the short duration of CPR (< or = 15 min) was the only factor significantly associated with better survival. CONCLUSIONS: Although prehospital care was provided by physicians, the overall rate of survival was found to be equally poor as reported from systems with paramedics. The only major difference between physician- and paramedic-staffed emergency care units is the ability of physicians to refrain from resuscitation already on the scene when prognosis is poor.     

Cardiopulmonary resuscitation. New and controversial techniques

Primary care physicians may need to perform cardiopulmonary resuscitation (CPR) from time to time. Knowledge regarding CPR has become extensive, and it is hoped that greater success will be achieved in the future with the advent of new methods. A number of techniques and devices have received attention in the lay and professional press. If appropriate care is to be delivered, practicing physicians must be aware of what is proven technology and what is investigational.     

Localization of the mRNA for the angiotensin II receptor subtype 2 (AT2) in follicular granulosa cells of the rat ovary by nonradioactive in situ hybridization

Changes in medicine brought on by health care reform will increasingly pressure physicians and physicians-in-training to adopt business or trade strategies in the name of cost containment and of competition in the health care marketplace. These strategies run directly counter to the professional standards and are a potential threat to medicine's status as a profession. A challenge for this generation of students is not to let this emphasis on finances erode medicine's professionalism. Medical faculty must ensure that their students properly understand the nature of the relationships that permit medicine to enjoy the benefits of being a profession (rather than a trade) and that they learn the appropriate balance between financial and professional considerations. Faculty can and should place financial considerations in proper perspective. Students should learn the basic components of professionalism, how physicians in the past have not always met the full criteria for professionalism, how the current emphasis on cost containment could threaten medicine's status as a profession, appropriate goals for health care reform, the need to form new alliances to meet those goals, and criteria for forming appropriate alliances. Armed with this knowledge, the generation of physicians now in training can understand the delicate balance that must be maintained between financial exigencies and professional imperatives. They will then be prepared to participate in the reform process, embrace its positive aspects, and argue effectively against its negative ones.     

Future directions for resuscitation research. III. External cardiopulmonary resuscitation advanced life support

This discussion about advanced cardiac life support (ACLS) reflects disappointment with the over 50% of out-of-hospital cardiopulmonary resuscitation (CPR) attempts that fail to achieve restoration of spontaneous circulation (ROSC). Hospital discharge rates are equally poor for in-hospital CPR attempts outside special care units. Early bystander CPR and early defibrillation (manual, semi-automatic or automatic) are the most effective methods for achieving ROSC from ventricular fibrillation (VF). Automated external defibrillation (AED), which is effective in the hands of first responders in the out-of-hospital setting, should also be used and evaluated in hospitals, inside and outside of special care units. The first countershock is most important. Biphasic waveforms seem to have advantages over monophasic ones. Tracheal intubation has obvious efficacy when the airway is threatened. Scientific documentation of specific types, doses, and timing of drug treatments (epinephrine, bicarbonate, lidocaine, bretylium) are weak. Clinical trials have failed so far to document anything statistically but a breakthrough effect. Interactions between catecholamines and buffers need further exploration. A major cause of unsuccessful attempts at ROSC is the underlying disease, which present ACLS guidelines do not consider adequately. Early thrombolysis and early coronary revascularization procedures should also be considered for selected victims of sudden cardiac death. Emergency cardiopulmonary bypass (CPB) could be a breakthrough measure, but cannot be initiated rapidly enough in the field due to technical limitations. Open-chest CPR by ambulance physicians deserves further trials. In searches for causes of VF, neurocardiology gives clues for new directions. Fibrillation and defibrillation thresholds are influenced by the peripheral sympathetic and parasympathetic nervous systems and impulses from the frontal cerebral cortex. CPR for cardiac arrest of the mother in advanced pregnancy requires modifications and outcome data. Until more recognizable critical factors for ROSC are identified, titrated sequencing of ACLS measures, based on physiologic rationale and sound judgement, rather than rigid standards, gives the best chance for achieving survival with good cerebral function.     

Risk factors and clinical outcomes between fungal and bacterial keratitis: a comparative study

OBJECTIVE: Thirty years ago, cardiopulmonary resuscitation (CPR) was primarily developed for otherwise healthy individuals who experienced sudden cardiac arrest. Today, CPR is widely viewed as an emergency procedure that can be attempted on any person who undergoes a cessation of cardiorespiratory function. Therefore, the appropriateness of CPR has been questioned as a matter of the outcome, the patient's preferences, and the cost. The objective of this article is to analyse ethical issues in prehospital resuscitation. ARGUMENTS: CPR is bound by moral considerations that surround the use of any medical treatment. According to Beauchamp and Childress, the hierarchy of justification in biomedical ethics consists of ethical theories, principles, rules, and particular judgements and actions. The decision to start CPR is based on the medical judgement that a person is suffering from circulatory arrest. The decision is justified by the moral rule that the victim of a cardiac arrest has the right to survive and to receive CPR. Moral rules are more specific to contexts and are based on ethical principles. The principle of beneficence means the provision of benefits for the promotion of welfare. Talking about beneficence in resuscitation means once again reporting stories of success, as many victims of pre- and in-hospital sudden death have been saved in the past. Nevertheless, resuscitative efforts still remain unsuccessful in the majority of cases, involving the principle of nonmaleficence. There is potential harm in CPR. Survivors may recover cardiac function, but sustain severe hypoxic brain damage, at worst surviving without awakening for months or years. In particular, post-traumatic CPR is associated with an extremely poor outcome, leading to the issue of futility. However, futility should be defined in a strict fashion, as there might be an individual chance of survival. The principle of respect for autonomy means the right of a patient to accept or reject medical treatment, which continues in emergency conditions and after the patient has lost consciousness. The time frame in CPR requires medical decision-making within seconds, and CPR is usually initiated without the patient's involvement. If the patient's wish's can be ascertained later on, life-sustaining therapies might be withdrawn at the time. Terminally ill but still competent patients should be encouraged to write a no-CPR document, which does not deny patients relief from severe symptoms, but might facilitate withholding resuscitative efforts at the scene. The principle of justice affects priorities in the allocation of health care resources. The decision made for a particular patient might delay or prevent emergency treatment in other patients who could receive greater benefit. CONCLUSIONS: The standard of care remains the prompt initiation of CPR. However, ethical principles such as beneficence, nonmaleficence, autonomy, and justice have to be applied in the unique setting of emergency medicine. Physicians have to consider the therapeutic efficacy of CPR, the potential risks, and the patient's preferences.     

Diabetic foot ulcers: prevention, diagnosis and classification

Diabetic ulcers are the most common foot injuries leading to lower extremity amputation. Family physicians have a pivotal role in the prevention or early diagnosis of diabetic foot complications. Management of the diabetic foot requires a thorough knowledge of the major risk factors for amputation, frequent routine evaluation and meticulous preventive maintenance. The most common risk factors for ulcer formation include diabetic neuropathy, structural foot deformity and peripheral arterial occlusive disease. A careful physical examination, buttressed by monofilament testing for neuropathy and noninvasive testing for arterial insufficiency, can identify patients at risk for foot ulcers and appropriately classify patients who already have ulcers or other diabetic foot complications. Patient education regarding foot hygiene, nail care and proper footwear is crucial to reducing the risk of an injury that can lead to ulcer formation. Adherence to a systematic regimen of diagnosis and classification can improve communication between family physicians and diabetes subspecialists and facilitate appropriate treatment of complications. This team approach may ultimately lead to a reduction in lower extremity amputations related to diabetes.     

Helping victims of violence in Uganda

We report on a project to assist victims of war and violence in Uganda. The original aim of this project, set up by the Medical Foundation for the Care of Victims of Torture, was to establish a centre for the assessment and treatment of torture victims who had suffered during previous regimes in that country. We found, however, that a specialist centre was not the most appropriate response in a country like Uganda. We argue for the need to respect local initiatives and systems of support and against the notion that there is a single model of care which is universally relevant. Following much investigation and involvement with local personnel, we have developed a programme of training and discussion for health workers, and a service to reach the many women who have suffered rape, and whose suffering has continued, largely ignored.     

Rating the appropriateness of coronary angiography--do practicing physicians agree with an expert panel and with each other?

BACKGROUND: Evaluations of the appropriateness of medical care are important to monitor the quality of care and to contain costs and enhance safety by reducing inappropriate care. Experts' views are usually incorporated into evaluations of appropriateness. However, practicing physicians may not concur with these views, and physicians' clinical backgrounds may influence their beliefs. METHODS: We asked 1058 internists, family practitioners, and cardiologists in California, Florida, New York, Pennsylvania, and Texas to rate the appropriateness of coronary angiography after acute myocardial infarction for 20 common indications. Nine clinical experts also rated these indications using an established consensus method. RESULTS: For 17 of the 20 indications, median ratings of surveyed physicians and the expert panel agreed within 1 unit on a 9-unit scale. Patients' older age had a negative effect on ratings by the expert panel but not on ratings by surveyed physicians. In multivariable analyses of surveyed physicians, cardiologists rated angiography as significantly more appropriate than did primary care physicians for complicated indications, and for uncomplicated indications cardiologists who performed invasive procedures gave higher appropriateness ratings for angiography than did cardiologists who did not perform such procedures and primary care physicians. For uncomplicated indications, physicians from hospitals providing coronary angioplasty and bypass surgery rated angiography as more appropriate than physicians from other hospitals. Physicians from New York and those employed by health maintenance organizations rated angiography as less appropriate than other physicians. CONCLUSIONS: Surveyed physicians agreed with clinical experts about the appropriateness of coronary angiography after myocardial infarction for most indications, indicating that well-designed expert panels can closely reflect the views of practicing physicians. Variations in beliefs among practicing physicians suggest that evaluations of medical practice should incorporate the views of a range of relevant types of physicians.     

The computer-based patient record challenges towards timeless and spaceless medical practice

Although computerization is increasingly advocated as a means for hospitals to enhance quality of care and control costs, few studies have evaluated its impact on the day-to-day organization of medical work. This study investigated a large Computerized Patient Record (CPR) project ($50 million U.S.) aimed at allowing physicians to work in a completely electronic record environment. The present multiple-case study analyzed the implementation of this project conducted in four hospitals. Our results show the intricate complexity of introducing the CPR in medical work. Profound obstructions to the achievement of a tighter synchronization between the care and information processes were the main problems. The presence of multiple information systems in one (Communication, Decision Support, and Archival record keeping) was overlooked. It introduced several misconceptions in the meaning and codification of clinical information that were then torn apart between information richness to sustain clinical decisions and concision to sustain care coordination.     

Domestic violence. Reality for some of your toughest patients

Until recently, domestic violence was considered a criminal justice or social service problem. However, physicians see victims in emergency settings and clinics with complaints and symptoms that go beyond physical injuries. A study by a Minnesota health plan shows that, on average, a victim of domestic violence costs the health care system $1,434 more per year than a nonvictim. This article discusses the prevalence of domestic violence and the variety of presentations. Guidelines for screening, what to do with a positive response, when to call the police, and how to document and code are reviewed, as are issues unique to older victims of domestic violence.     

The development of international emergency medicine: a role for U.S. emergency physicians and organizations. SAEM International Interest Group

There is a rapidly growing interest in emergency medicine (EM) and emergency out-of-hospital care throughout the world. In most countries, the specialty of EM is either nonexistent or in an early stage of development. Many countries have recognized the need for, and value of, establishing a quality emergency health care system and are striving to create the specialty. These systems do not have to be high tech and expense but can focus on providing appropriate emergency training to physicians and other health care workers. Rather than repeatedly "reinventing the wheel" with the start of each new emergency care system, the preexisting knowledge base of EM can be shared with these countries. Since the United States has an advanced emergency health care system and the longest history of recognizing EM as a distinct medical specialty, lessons learned in the United States may benefit other countries. In order to provide appropriate advice to countries in the early phase of emergency health care development, careful assessment of national resources, governmental structure, population demographics, culture, and health care needs is necessary. This paper lists specific recommendations for EM organizations and physicians seeking to assist the development of the specialty of EM internationally.     

A collaborative program for advanced practice in trauma/critical care nursing

The students and faculty enrolled in the first TNP class have set a standard for future TNPs: a rigorous course of education with advanced practice and scholarship within an advanced practice collaborative model. Because of the increasingly number of trauma victims and the highly specialized care they require, nurses must come forward and provide quality care. The TNPs and their faculty must promote further recognition of the TNP role, become leaders in the field of acute care, and continue to develop and maintain collaborative relationship with physicians in support of advanced practice nursing in many areas of tertiary care. The first three graduates of the trauma/critical care practitioner class are now employed in advanced practice roles and are applying their education within trauma/critical care settings. Two of the students are trauma nurse practitioners in a community hospital, and one is a critical care nurse practitioner in a university hospital. Currently, there is an acute care nurse practitioner certification examination that is appropriate for nurses in the field of trauma/critical care. Co-sponsored by the AACN Certification Corporation and the American Nurses Credentialing Center, this examination is offered twice a year, in June and October. AACN is active in supporting and promoting the TNP role and, in conjunction with the American Nurses Association, has developed new standards of care and scope of practice to include this expanded role for the advanced practice nurse. The future for this exciting and demanding role looks bright for the advanced practice nurse interested in the care of the acutely ill patient. The time is right for this collaboration between nurses and physicians.     

Withholding medical care as a physical injury--homicide from the viewpoint of the physician

Limitation and termination of intensive care and in particular life support in patients who do not have a chance to recover from their illness has become a widely accepted approach in intensive care medicine. In well defined situations, life support can be withheld or withdrawn without the risk of becoming a criminal case. Frequently, the physician must base his/her decision on the presumed will of the patient which can be difficult to assess. Existing guidelines of the Society of physicians of Germany, which are partly preliminary, are helpful for the decision process of the physicians as well as of the relatives of the patients.     

A crash course in spinal cord injury

The complex management issues related to spinal cord injury traditionally have been the purview of physical medicine and rehabilitation specialists. However, changes in the healthcare system now offer primary care physicians an expanded role in helping affected patients live a healthier and more functional life. With proper understanding of the mechanisms of spinal cord injury, primary care physicians can become important members of the medical management team. Dr Yu presents a comprehensive overview of medical care issues and common complications in spinal cord injury.     

Establishing a high-school-based training room clinic

Being a team physician can be a time-consuming commitment. The team physician is responsible for all aspects of the athlete's care and has the final say in all medical matters related to athletic participation. Primary care physicians are well suited to be team physicians. The training room is an outstanding way to increase physician availability to adolescents and underserved population. Setting up a training room must be planned in advance, including funding, supplies and liability. Most legal problems can be avoided with a contract and proper documentation. The school-based training room provides the physician with an excellent opportunity for community service and can be a very rewarding experience.     

Advance directives and other medical decisions concerning the end of life in cancer patients in Japan

The purpose of our survey was to investigate the experience of physicians regarding advance directives and other medical decisions concerning the end of life. A postal questionnaire was sent to 500 Japanese physicians who were most involved in medical care of terminal patients. A total of 339 (68%) physicians responded. In dealing with terminal patients, approximately half gave priority to their patients' wishes for medical care, if known, regardless of the patient's competency. Of the respondents, 149 had been presented with advance directives by their patients and 35% followed all advance directives presented in their practice. Cardiopulmonary resuscitation (CPR) for arrested patients to enable their family to be at the bedside at the time of the death was common. More than 60% of the respondents thought that active euthanasia and assisted suicide were never ethically justified. Our study indicates that the wishes of patients are currently not always given top priority in medical decisions concerning the end of life.     

The role of the primary care physician in the care of children with serious heart disease

OBJECTIVE: To determine the roles of primary care physicians and specialists in the medical care of children with serious heart disease. SETTING: Pediatric Cardiology Division; Tertiary Care Children's Hospital. SUBJECTS: Convenience sample of parents, primary care physicians, and pediatric cardiologists of 92 children with serious heart disease. DESIGN: Questionnaire study; questionnaires based on 16 medical care needs, encompassing basic primary care services, care specific to the child's heart disease and general issues related to chronic illness. RESULTS: All children had a primary care physician (PCP), and both they and the parents (P) reported high utilization of PCP for basic primary care services. However, there was little involvement of PCP in providing care for virtually any aspect of the child's heart disease. Parents expressed a low level of confidence in the ability of PCP in general or their child's own PCP to meet many of their child's medical care needs. Both PCP and pediatric cardiologists (PC) were significantly more likely than parents to see a role for PCP in providing for care specific to the heart disease as well as more general issues related to chronic illness. PC and PCP generally agreed about the role PCP should play, although PC saw a bigger role for PCP in providing advice about the child's activity than PCP themselves did. PC were less likely to see the PCP as able to follow the child for long term complications than PCP did. PC were more likely than PCP to believe that PCP were too busy or were inadequately reimbursed to care for children with serious heart disease. Only about one-third of parents reported discussing psychosocial, family, economic, or genetic issues with any provider, and PCP were rarely involved in these aspects of chronic illness. CONCLUSIONS: Primary care physicians do not take an active role in managing either the condition-specific or the more general aspects of this serious chronic childhood illness. With appropriate information and support from their specialist colleagues primary care physicians could provide much of the care for this group of children. Generalists and specialists are both responsible for educating and influencing parents about the role primary care physicians can play in caring for children with serious chronic illness.     

Moderate head injuries in children as compared to other age groups, including the cases who had talked and deteriorated

Patients defined as having a moderate head injury on the basis of Glasgow Coma Scale scores within the ranges of 9 to 13 after acute nonsurgical procedures were selected. Almost 1600 cases were hospitalized in the Neurosurgery Department. The cases were admitted through the Emergency Unit of Gaz University Medical School, Ankara, Turkey during the period between 1979 and 1992. The group studied consisted of 231 selected patients assessed separately in paediatric, adult and elderly age groups. Possible risk factors such as: GCS score, anisocoria, unilateral or bilateral fixed pupils, impaired oculocephalic reflexes, presence of multiple systemic injuries, aetiology of head trauma, presence of linear or depressed skull fractures, space occupying mass on CT or operation was also assessed. Subarachnoid haemorrhage turned out to be the only independent significant risk factor in predicting mortality. The data about the patients who have "talked and deteriorated" were also reported so as to assisst physicians charged with the care of trauma victims.     

Domestic violence: examining nurses' and doctors' management, attitudes and knowledge in an accident and emergency setting

Despite the increasing awareness of the important role that Accident and Emergency (A&E) personnel have in the diagnosis and management of domestic violence victims, there is limited knowledge about the nurses' or doctors' knowledge of or attitudes to domestic violence in Australian health care settings. In addition nursing and medical staff still receive very little training in working with domestic violence victims. This study was conducted to examine the existing knowledge, attitudes to and management strategies for domestic violence victims among 111 nurses and doctors in two rural and two country hospitals. The findings indicate that A&E staff recognise the importance of their role in the identification and management of domestic violence victims. Despite this they do not have all the skills necessary to deal effectively with the problem or to be able to access local resources for assistance. Education programs should focus on direct questioning techniques, and recognition of risk factors and protocols to provide guidelines for police involvement.
