Abstract
As the largest organ in the body, skin can prove the most daunting to diagnose and manage due to the large number of conditions and their uncanny ability to have similar qualities visually. Skin can reflect current trauma or infections or can be a harbinger of an underlying systemic disorder. With knowledge of the most common pediatric skin conditions, it is possible for practitioners to start a child on a basic treatment regimen and then refer to an appropriate specialist for more complex or rare disorders. This article covers the most common skin conditions seen on the lower extremity in the pediatric population.

Abstract
Human infighting has been a part of our civilization since times immemorial. These incidences may go unnoticed or may attract attention of law enforcing agencies depending upon the severity of the offence. Though weapons are generally employed to inflict injuries, rare cases have been reported in literature where human teeth have been used to serve this purpose. Human bites may be self inflicted or self suffered in connivance with others to level an allegation against an adversary. We are presenting here such a case where such injuries were produced to bring a false charge against a neighbor.

Abstract
BACKGROUND Mammalian bite injuries create a public health problem because of their frequency, potential severity, and increasing number. Some researchers have performed fragmentary analyses of bite wounds caused by certain mammalian species. However, little practical information is available concerning serious mammalian bite wounds that require hospitalization and intensive wound management. Therefore, the purpose of this study was to perform a general review of serious mammalian bite wounds. METHODS We performed a retrospective review of the medical charts of 68 patients who were referred to our plastic surgery department for the treatment of bite wounds between January 2003 and October 2012. The cases were analyzed according to the species, patient demographics, environmental factors, injury characteristics, and clinical course. RESULTS Among the 68 cases of mammalian bite injury, 58 (85%) were caused by dogs, 8 by humans, and 2 by cats. Most of those bitten by a human and both of those bitten by cats were male. Only one-third of all the patients were children or adolescents. The most frequent site of injury was the face, with 40 cases, followed by the hand, with 16 cases. Of the 68 patients, 7 were treated with secondary intention healing. Sixty-one patients underwent delayed procedures, including delayed direct closure, skin graft, composite graft, and local flap. CONCLUSIONS Based on overall findings from our review of the 68 cases of mammalian bites, we suggest practical guidelines for the management of mammalian bite injuries, which could be useful in the treatment of serious mammalian bite wounds.

Abstract
Dog attacks are extremely frequent and are thought to be responsible for an average of 250,000 minor injuries and emergency unit attendances each year. Children in particular are more likely to experience dog-bite injuries with 5-9-year olds most susceptible. The majority of injuries are to the head region, with the lips, cheeks, and nose often affected. Most injuries experienced are confined to the soft tissues; nevertheless, maxillofacial fracture is a potential albeit rare complication. The incidence of facial fractures in relation to dog bites is unknown; however, some have estimated that facial fractures could occur in 5% of dog attacks. However mandibular fracture following a dog bite is extremely rare, with review of the literature only identifying three cases. We present a further case in which a five-year-old sustained numerous soft-tissue lacerations to the face and hand, together with fracture of the mandibular symphysis following a dog attack. The fracture was successfully repaired using open reduction and internal fixation with titanium plates and screws. The case emphasises that although maxillofacial fracture is rare, it may occur following a dog bite and that thorough and systematic examination of the facial skeleton is crucial to exclude the presence of such injuries.

Abstract
OBJECTIVES (1) Using clearly defined methods, provide a current assessment of the epidemiology of human bites sustained by pediatric patients evaluated at a pediatric ED; (2) Compare the frequency, demography, locations, and management of these injuries from the results of the current study to the 2 prior ED studies on pediatric human bites; and (3) Determine if the frequency of these injuries varies by year, gender, or body location. METHODS The current study involved a retrospective analysis of all visits to an urban, northeastern, United States pediatric ED from 1995 to 2001. Visits for human bites were identified by International Classification of Disease, Ninth Revision, Clinical Modification codes using 2 separate computerized billing databases. Data were extracted from 2 prior published studies for the comparative portion of the study. Frequency estimates and 95% confidence intervals were created using STATA7. RESULTS For the current study, there were 115 visits for human bites, which comprised 0.04% [0.03-0.05] of total visits to this pediatric ED. Bite visits as a percentage of pediatric ED visits remained the same during the 7 years of the current study. For all 3 pediatric EDs, human bites consisted of much less than 1% of the overall patient volume. The majority (65% [55.8-73.9]) of the patients in the current study were male. When adjusted for the frequency of all patient visits by gender, there was no statistically significant difference in percentage of visits for human bites between males and females (0.05% [0.039-0.063] vs. 0.03% [0.023-0.044]) in the current study. Prior studies did not reveal a statistically significant predominance of males presenting for human bites. As a percentage of visits by age group, human bites were more frequent among adolescents in the current study. Altercations and child play were reported approximately equally as the circumstances contributing to the bites in the current study, although altercations were reported more often in older age groups. In all 3 studies, fewer than 14% of patients were admitted and over 80% presented within 12 or 24 hours after the bite. CONCLUSIONS Pediatric ED visits for human bites are infrequent and from the current study data, the frequency of visits for these injuries appears to be currently stable. Altercations may not be the main circumstances surrounding all pediatric human bites, yet altercations and human bites might be jointly associated with adolescence. The current study results suggest that most pediatric ED human bite patients are male, although males may not necessarily sustain human bites more frequently than females. Visits for human bite injuries may increase in frequency with age, in comparison to visits for other medical conditions.

Abstract
The epidemiology of human bites and blood exposures in urban schools has not been described. The authors reviewed 734 human bite and blood exposure incidents in New York City schools from September 1999 to June 2001. School site, age, gender, body site, temporal distributions, and underlying health status of individuals were reviewed. Nine incidents involved children known or suspected to be HIV-infected. Medical interventions included EMS involvement, emergency room treatment, hospitalization, vaccine administration, laceration suturing, systemic antibiotic therapy, and serologic evaluation for transmission of blood-borne pathogens. These incidents occur with a high prevalence in NYC schools and have potential for serious outcomes.

Abstract
Bite wounds are frequently located on the face; injuries inflicted by dogs are most common, especially in children. Bacteriology of infected dog and cat bite wounds includes Pasteurella multocida, Staphylococcus aureus, viridans streptococci, Capnocytophaga canimorsus, and oral anaerobes. Infected human bites yield a similar spectrum of bacteria except for Pasteurellae and C. canimorsus; instead human bites are frequently complicated by Eikenella corrodens. Antibiotic therapy against these bacteria is indicated both for infected bite wounds and fresh wounds considered at risk for infection. Amoxicillin-clavulanate (and other combinations of extended-spectrum penicillins with beta-lactamase inhibitors) and moxifloxacin offer the best in vitro coverage of the pathogenic flora. Initial wound management consisting in irrigation and debridement is at least equally important with antibiotics for prevention of infection. The need for prophylaxis against systemic infectious complications, particularly tetanus, should also be evaluated. Primary surgical repair is the treatment of choice for most clinically uninfected facial bite wounds, whereas delayed closure should be reserved for certain high risk or already infected wounds. Avulsive injuries with significant tissue loss represent the most difficult cases for definitive management and are also those most likely to require hospitalization.

Abstract
To assess the need for antibiotics in low-risk human bite wounds, a prospective, double-blind, placebo-controlled study involving 127 patients presenting with low-risk human bite wounds over 2 years to a 40,000 visit per year major academic ED was performed. Low-risk bites penetrated only the epidermis and did not involve hands, feet, skin, overlying joints, or cartilaginous structures. Exclusion criteria included age less than 18 years, puncture wounds, immunocompromise, allergy to penicillin or related compound, or bites greater than 24 hours old. Patients were randomly assigned to receive either a cephalexin/penicillin combination or placebo. One hundred twenty-five patients completed the study. Infection developed in 1 of 62 patients receiving placebo (1.6%, 95% confidence interval CI, 0-7.3%). Infection developed in 0 of 63 patients receiving the cephalexin/penicillin combination (0%, 95% CI, 0-4.6%). Antibiotic treatment of some low-risk human bite wound could be unnecessary. Infection rates appear similar in low-risk human bite wounds whether treated with antibiotics or placebo.

Abstract
The goals of wound management are simple: avoid infection and achieve a functional and aesthetically pleasing scar. This is achieved by reducing tissue contamination, debriding devitalized tissue, and restoring perfusion in poorly perfused wounds, in conjunction with a well-approximated skin closure.

Abstract
Clenched fist injuries to the mouth ("fight bite") are notorious for being the worst human bites. These are often treated as minor injuries, without the recognition that the joint capsule, the extensor tendon, or the deep fascial spaces may have been violated and contaminated with oral bacteria. Significant morbidity can result from late presentation or inadequate initial management. The emergency physician needs to remain vigilant for complications associated with closed fist injury. This review article examines the clinical presentation, diagnostic techniques, and management options applicable to the emergency physician in the treatment of fight bite.

Abstract
The likelihood of high-risk pediatric exposure to HIV infection, other than perinatal exposure, has been shown to be low in most cases, and HIV PEP should be considered on a case-by-case basis. Generic considerations in the management of children who have become HIV infected emphasizes the principles of inclusion, maintaining confidentiality of a child's HIV status, and notifying those who need to know about the HIV status to care properly for the child or adolescent. Although appropriate infection-control precautions are applicable for all children and for many pathogens, children especially HIV-infected children, exposed to such pathogens, must be managed in a timely fashion. In many cases, recommendations that are applicable in one setting are applicable in others. Some exceptions apply, including infection-control precautions in hospitals versus other settings. A few additional considerations have been made for special settings and activities, including adoption, foster care, athletics, summer camp, and other recreational activities.

Abstract
OBJECTIVE Suturing of bite wounds remains controversial. The authors evaluated the incidence of wound infection in 145 mammalian bite wounds treated with primary closure. METHODS Consecutive patients with bite wounds receiving primary closure at a university hospital ED had structured closed-question data sheets completed at the time of wound management and suture removal. Infection was determined at the time of suture removal using a previously validated definition. Data included demographics; medical history; time from injury to evaluation; wound characteristics and location; details of wound cleansing methods, debridement, foreign body removal, and wound closure methods; use of antibiotics; and follow-up wound evaluation. Proportions and 95% confidence intervals were calculated. RESULTS One hundred forty-five mammalian bite patients were enrolled: 88 dog, 45 cat, and 12 human bites. Patients had a mean (+/-SD) age of 21 +/- 20 years; 58% were male; 86% were white; and they presented a mean (+/-SD) of 1.8 +/- 1.2 hours after injury. Bites occurred on the head and neck (57%), upper extremity (36%), and lower extremity (6%). Wounds had a mean length and width of 2.5 cm and 4.8 mm, respectively. Twelve percent involved structures deep to subcutaneous tissue. After primary wound closure, wound infections occurred in eight patients (5.5%; 95% confidence interval = 1.8% to 9.2%). CONCLUSIONS The data suggest that carefully selected mammalian bite wounds can be sutured with approximately a 6% rate of infection. This infection rate may be acceptable in lacerations where cosmesis is a primary concern.

Abstract
The risk of human immunodeficiency virus (HIV) transmission following a bite injury is important to many groups of people. The first are those who are likely to be bitten as an occupational risk, such as police officers and institutional staff. Another group are represented by the victims and perpetrators of crimes involving biting, both in attack and defense situations. The possibility of these bites transmitting a potentially fatal disease is of interest to the physicians who treat such patients and the legal system which may have to deal with the repercussions of such a transmission. Bite injuries represent 1% of all emergency department admissions in the United States, and human bites are the third most common following those of dogs and cats. The worldwide epidemic of HIV and acquired immunodeficiency syndrome (AIDS) continues, with >5 million new cases last year and affecting 1 in 100 sexually active adults. A review of the literature concerning human bites, HIV and AIDS, HIV in saliva, and case examples was performed to examine the current opinion regarding the transmission of HIV via this route. A bite from an HIV-seropositive individual that breaks the skin or is associated with a previous injury carries a risk of infection for the bitten individual.

Abstract
PURPOSE Because of the large number of bacteria in the oral cavity, animal bite wounds are generally contaminated, and their treatment is difficult because of the risk of infection, especially in extensive injuries. This report describes the management of a large series of patients and recommends treatment guidelines on the basis of the results. PATIENTS AND METHODS Ninety-four animal bite wounds on the face and head were analyzed according to the type of animal, location and extent of the soft tissue wound, duration and type of surgical treatment, occurrence of infections and their pathogen spectrum, as well as the choice of antibiotic therapy. RESULTS Dogs caused 91% of the bite wounds. Infections developed in 4 of 53 patients who underwent primary wound closure with minor edge excision and prophylactic administration of oral penicillin. Without antibiotic administration, 2 of 15 patients had infections, which were treated on an outpatient basis. Of 26 patients with initially delayed treatment, 18 showed clinical inflammatory symptoms with a wide spectrum of pathogens (Escherichia coli, Streptococcus, Enterococcus, Staphylococcus epidermidis, and Proteus) on presentation. CONCLUSION Extensive animal bite wounds on the face, even with soft tissue defects, should be treated according to the criteria of a esthetic reconstructive facial surgery. In view of the low infection rate, routine antibiotic prophylaxis is not justified.

Abstract
Wound cultures represent a general catchall category for a group of extremely diverse anatomic samples that range from superficial specimens of cutaneous structures (folliculitis, cellulitis) to specimens revealing invasive infections involving deep fascial planes and muscle (myonecrosis). Because of the complex nature of these infective processes, the terminology associated with such infections is often imprecise and confusing. Wounds are the result of trauma, either intentionally or accidentally induced. Nosocomial wound infections result primarily from surgical procedures, the development of pressure sores, or catheterization. Community-acquired wound infections are often preceded by injuries resulting from occupational exposure or recreational activities and are associated with a greater diversity of microorganisms due to the exposure of open wounds to inhabitants of the microbial biosphere. This review provides a general overview of the categories of wound infections and describes their acquisition and clinical significance. Particular emphasis is placed on selected community-acquired wound infections and the etiologic agents associated with such conditions.

Abstract
It is estimated that half of all Americans will be bitten by an animal or another human being during their lifetimes. The vast majority of the estimated 2 million annual mammalian bite wounds are minor, and the victims never seek medical attention. Nonetheless, bite wounds account for approximately 1% of all emergency department visits and more than $30 million in annual health care costs. Infection is the most common bite-associated complication; the relative risk is determined by the species of the inflicting animal, bite location, host factors, and local wound care. Most infections caused by mammalian bites are polymicrobial, with mixed aerobic and anaerobic species. The clinical presentation and appropriate treatment of infected bite wounds vary according to the causative organisms. Human bite wounds have long had a bad reputation for severe infection and frequent complication. However, recent data demonstrate that human bites occurring anywhere other than the hand present no more of a risk for infection than any other type of mammalian bite. The increased incidence of serious infections and complications associated with human bites to the hand warrants their consideration and management in three different categories: occlusional/simple, clenched fist injuries, and occlusional bites to the hand. This article reviews dogs, cat, and human bite wounds, risk factors for complications, evaluation components, bacteriology, antimicrobial susceptibility patterns, and recommended treatments. Epidemiology, clinical presentation, and treatment of infections caused by Pasteurella multocida, Capnocytophaga canimorsus, Eikenella corrodens, and rhabdovirus (rabies only) receive particular emphasis.
