Differential Diagnosis of Bruising • Accidental injury—commonly on bony surfaces roxithromycin 150 mg line, appropriate history roxithromycin 150mg discount. Investigations In the presence of excessive or reported spontaneous bruising discount roxithromycin 150mg with amex, it is rea- sonable to exclude an underlying bleeding disorder. Suggested tests include full blood count, platelet count, prothrombin time, thrombin time, partial thromboplastin time, fibrinogen level, and bleeding time (after discussion with a hematologist). Bite Marks A bite mark is a mark made by teeth alone or in combination with other mouth parts and may be considered a mirror image of the arrangement and characteristics of the dentition. Human bite marks rarely occur accidentally Nonaccidential Injury in Children 167 and are good indicators of inflicted injury. Children can be bitten in the con- text of punishment, as part of a physical assault, or in association with sexual abuse. Factors influencing the appearance of a bite mark include the following: • The status of the skin (ante- or postmortem) and the skin condition. Good Practice Tips • When defined bite marks are found, advice should be sought from a forensic odontologist. Impressions and dental casts of suspects can be made that may be able to establish the identity of the perpetrator. The swabs should be air dried and man- aged according to standard procedures for the collection of forensic evidence (see Chapter 3). These should include a scale (rigid L-shaped measuring rule) and, when appro- priate, a color standard. Serial daily photographs are useful to record the bite mark’s evolution and optimum definition. Other Soft Tissue Injuries • Subgaleal hematoma—diffuse, boggy swelling on the scalp can occur following hair pulling (often associated with broken hairs and petechial hemorrhages). Direct trauma can also lead to corneal or scleral laceration or scarring, rup- tured globe, vitreous or retinal hemorrhage, acute hyphema, dislocated lens, traumatic cataract, and detached retina. Ulceration to the inner lips or cheeks from a blow to the face causing impac- tion of the tissues against teeth, torn frenulum from a blow to the upper lip, or penetrating injury from a feeding utensil. Abrasions or lacerations to the palate, vestibule, or floor of the mouth from penetrating injuries (e. Thermal Injury Burns and scalds to children can be inflicted, occur accidentally, or fol- low neglect. The injury can be superficial or partial or full-skin thickness, depending on the temperature and duration of exposure. Characteristically, the burn is shaped like the hot object, with sharply defined edges and usually of uniform depth. Accidental contact with a cigarette tends to leave a more superficial, irregular area of erythema with a tail. Nonaccidential Injury in Children 169 • Electrical burns—small, deeply penetrating burns with an entry and exit wound with possible necrosis of underlying tissues. Differential Diagnosis of Thermal Injuries • Accidental burns—appropriate history and presentation. Skeletal Injury Historically, skeletal injury played a major role in the recognition of child abuse (25,26). In 1946, Caffey (27) described six patients presenting with 170 Thomas chronic subdural hematoma in which 23 unexplained fractures of the long bones were found. Caffey concluded that the fractures were traumatic in ori- gin and introduced the concept of inflicted injury. Fractures in infants and children resulting from falls of under 3 ft are relatively uncommon. Research evidence suggests that 1% of children falling less than 3 ft may sustain a simple linear skull fracture (29). Accidental fractures in infants and toddlers do occur, usually as a result of falls, often from a height, but they can occasionally occur in long bones of ambulant children from twisting, running, and falling. Fractures cause pain and distress and are often accompanied by nonuse of the affected body part and local swelling. Other features of skeletal injury suggestive of abuse include the following: • Absence of an appropriate history. Precise dating of fractures cannot be achieved, although ranges of frac- ture ages are available. Advice from an experienced pediatric radiologist should be sought to assist with dating injuries, to obtain further radiological or other imaging views, and to exclude other causes of skeletal abnormality. Detecting occult injury is particularly important in the younger child and infant and recommended indications for a skeletal survey include the follow- ing (17,25,28,32): • Any child younger than 2 years when there is a suspicion of physical abuse. Differential Diagnosis of Skeletal Injury • Accidental injury—appropriate, consistent history, and prompt presentation. Intracranial Injury There is a high incidence of mortality and morbidity after inflicted head injury, and it is the most common cause of traumatic death in infancy (34). It has been generally accepted from research evidence that serious or fatal injury from accidental injury, other than that sustained in road traffic accidents or falls from major heights, is rare in children under 2 years and that simple skull fractures in accidental trauma have a low risk of intracranial sequelae (26). The mechanism of brain injury is considered to be a whiplash motion of acceleration and deceleration, coupled with a rotational force, during a shak- ing episode of an infant, where the head is unsupported. Shaking alone may lead to brain injury, although in many instances there may be other forms of head trauma, including impact injuries (35,36).

Advantages in training over real operational systems include: elimination of catastrophic consequences of error; reduction of physical danger; cost containment; elimination of nonsalient attributes; “replay” possibilities; com- pression or expansion of time; and iterative manipulation of variables for evolving design and data collection . The use of simulations in medical education, in general, and in disaster medicine educa- tion, in particular, is well documented [26–30]. When considering simulations, we distin- guish two different kinds: virtual and live. In the former, real people use simulated equip- ment in a simulated world (or virtual environment); in the latter, real people use simulated (or dummy) equipment in the real world. Interactive simulation systems ¿t the requirement of allowing social in- teraction, which is the key element in those scenarios where users are expected to cooper- ate in order to solve a particular problem, such as in response to disasters. Live simulations are major enterprises that demand many resources, a full staff of evaluators and control- lers, a complement of actors (victims and other event-impacted personnel) and realistic simulations of the physical damage and other consequences of the event. Participants at all levels must literally execute their tasks under the disaster plan on the operational ¿eld in real time. Unfortunately, there is no strong evidence to support ¿rm conclusions about the effec- tiveness of speci¿c training methods. The authors conclude that different types of training exercises may have differ- ent roles to play in educating hospital staff in disaster response. Gradually, this attitude changed to an empha- sis on preparedness measures, such as stockpiling of relief goods, preparedness plans and a growing role of education and training. Disasters might no longer be considered as extreme events created entirely by natural forces but as unresolved problems of development. This disaster preparedness and planning approach is the only key to improving the ef¿ciency of relief and response actions and reducing the impact of such inevitable events.

Chemical releases arising from techno- logical incidents, natural disasters, and conÀict and terrorism are common . The In- ternational Federation of Red Cross and Red Crescent Societies has estimated that be- tween 1998 and 2007, there were nearly 3,200 technological disasters with approximately 100,000 people killed and nearly 2 million people affected. Unfortunately, the threat of ma- jor events involving chemicals is predicted to increase worldwide for three main reasons. First, the chemical industry is rapidly growing, and the number of chemicals available in the market is increasing . Second, chemical incidents may have an impact beyond their original location, in some cases crossing national borders. Third, there is concern regard- ing the deliberate use of chemicals for terrorist purposes . Thus, emergency involving exposure to chemicals could represent one of the most common di- sasters that occur in the community setting. To minimise these negative impacts, and be- cause chemical incidents often involve acute releases and health risks with a very dynamic time course (as a result of changing conditions, e. It might be taken into consideration that a single patient exposed to a hazardous material may overwhelm even a modern, high-volume facility . Preparation begins with a thorough understanding of the threat and with the develop- ment of simple and ef¿cient countermeasures. When a chemical incident occurs, rapid and effective response is dependent on detailed prevention planning, appropriate medical treatment and subsequent postevent analysis to improve the quality of future response operations. Therefore, the term chemical incident might refer to events caused by humans, such as the explosion of a factory that stores or uses chemicals, contamination of food or water supply with a chemical, an oil spill, a leak in a storage unit during transportation or an outbreak of disease that is (likely to be) associated with chemical exposure. There is increasing awareness that natural disas- ters can trigger technological disasters and that these conjoint events may pose tremendous threats to regions, particularly those unprepared for such events. In fact, natural causes, such as volcanoes, earthquakes and forest ¿res, can cause chemical incidents. Natural disasters may disrupt chemical containment systems and cause secondary anthropogenic chemical incidents (e. The term natech disasters (natural- disaster-triggered technological disasters) refer to this type of incident . Chemical disasters caused by humans are the result of signi¿cant human action, either intentional or unintentional. Incidents in- volving the use of commercial or industrial chemicals have the potential to cause a major public health disaster comparable to that of known agents used for deliberate releases, such as vesicants or nerve gases. Chemical terrorism may actually occur as an intentional toxic chemical spill or release involving industrial and/or commercial products. In some cases, industrial agents are more likely to be used as weapons of choice by terrorists due to their Table 28. In effect, the main difference between uninten- tional industrial accidents and intentional chemical sabotage or terrorism may only be the distinction of malicious intent . In principle, chemical emergencies are more likely to occur where there are situations combining both high hazard and high vulnerability.
Part 46 of the code is entitled “Protection of Human Subjects” and provides the basic federal policy for the protection of human research subjects discount roxithromycin 150mg without prescription. The policy deﬁnes the code of conduct for research that includes the conﬁdentiality of patient data and identity generic 150mg roxithromycin otc. Any similar observations in other patients treated in this study or a similar study? Speciﬁcally discount roxithromycin 150mg amex, the committee must not be comprised of individuals of all one gender or profession. It must also be comprised of at least one member with relevant scientiﬁc expertise and one lay member and one member not afﬁliated with the institution or any family member of the institution. This report is to be followed by a written report ﬁled to each group as part of the clinical trial records keeping. The committee must comprise of a botanist or plant pathogen or plant pest containment expert as well as an animal contain- ment expert. The sponsoring institution is also required to train all members of the committee and utilize ad hoc experts as necessary. Signiﬁcant efforts are being made to generate international guidelines for human gene therapy research. An example of an individual country establishing its own guidelines for gene therapy research is Australia. In May, 1999, the Australian National Health and Medical Research Council published a consultation draft document entitled “Draft Guidelines for Human Somatic Cell Gene Therapy and Related Technologies. These guidelines should in inter- preted in concert with the National Health and Medical Research Council’s “statement”, Statement on Ethical Conduct in Research Involving Humans. Research protocols are brought to the Genetic Manipulation Advisory Committee that has a mission to oversee the development and use of novel genetic manipula- tion techniques as well as assess whether these techniques pose a hazard to the com- munity or environment. Some of these procedures are patterned after the “Appendix M” documents of the United States. The reader is directed to the executive summary of “Stem Cell Research: Medical Progress with Responsibility” a report from the chief medical ofﬁcer’s expert group reviewing the potential of developments in stem cell research and cell nuclear replacement to beneﬁt human health. This document contains nine speciﬁc recom- mendations for guidelines for medical research in the areas of nuclear transfer and stem cells. It is currently before the Parliament of Great Britain for approval and can be found on the Internet at: www. Subsequently, institutional administrative approval is needed for submission for approval at the federal level. However, each country will act and regulate these technologies on an individual basis according to its ethical, religious, and legal traditions. For example, while substantial efforts are being made to outlaw human cloning in the United States, Israel has determined that Rabbinical Law will allow for the cloning of humans. The Institutional Review Board and beyond: Future challenges to the ethics of human experimentation. An ethic, as deﬁned by Webster, is a principle of right or good conduct or a body of such principles. Ethics is the study of the general nature of morals and the speciﬁc moral choices to be made by the individual in his/her rela- tionship with others. A moral is deﬁned as of or concerned with the judgment of the goodness or badness of human action and character, that is, pertaining to the dis- cernment of good and evil. In the context of human gene therapy, the methods or procedure used to provide therapy of a disease is considered a “good. In the ﬁrst part we will be exploring these issues in a clin- ical context at the level of the doctor–patient relationship. Our focus will be somatic cell gene therapy, work that is now moving quickly into clinical trials. In the second part we will be exploring issues at the level of social and professional policy. In par- ticular, we will give considerable attention to ethical issues connected with germline genetic engineering. This is not a technical capacity we have as yet, but, as many have argued, it would be morally and politically foolish to put off having these discussions until the technology has been actualized. A case that is well known in the bioethics literature is that of David, who was usually referred to in the popular press as the “Texas Bubble Boy. His older brother had died of this disorder; and consequently, physicians were prepared at birth for David, who was expected to be born with the same disorder. Birth took place in an absolutely germ- free environment to protect David from exposure to any and all pathogens. His parents were able to modify their living room and create a room-size sterile bubble in which David grew up. At one point he was able to use a space suit of sorts to wander for brief periods in the outside world. At the age of 12 both David and his parents were hoping he would have access to some medical therapy that might free him from the conﬁnement of that bubble. Bone marrow transplant techniques were well developed by then and looked pro- mising. The hope was that her bone marrow would give David the immune system that he lacked. Things went well for a few months, but then David began to have a fever whose cause was unknown. It was later learned that his sister’s bone marrow harbored the Epstein–Barr virus.
