Abstract
OBJECTIVE The objective of this study was to investigate possible immune cytokine trends throughout a week-long surgical simulation mass-casualty training session in order to determine the effects of stress inoculation on the immune system. METHODS Thirty-seven military medical students participated in a hyper-realistic surgical simulation training event conducted at Strategic Operations site in San Diego, California. Salivary samples were collected every morning of the stress training exercise for 4 consecutive days. Cortisol, along with a panel of 42 immune cytokines, was measured using multiplex enzyme-linked immunosorbent assays from Eve Technologies. The determined concentrations were averaged and plotted on a scatter plot, and then points were fit to a second-order polynomial trendline of best fit to measure. RESULTS The cytokines epidermal growth factor, growth-related oncogene-α, interleukin (IL)-1α, and platelet-derived growth factor-AA followed a noted pattern of cortisol decrease throughout the week. In addition, cytokines IL-27, granulocyte colony stimulating factor, IL-10, and IL-13 demonstrated a late peak, followed by a return to baseline at the conclusion of training. Finally, the cytokine monocyte chemoattractant protein-1 displayed a decline throughout the week followed by an increase on the last day of stress training. CONCLUSIONS Altogether, these results help to identify important biomarkers that may help to improve long-term stress adaptation and prevent post-traumatic stress disorder following exposure to repeated stress.

Exploring the relationship of supernumerary recurrent renal calculi formation and tick-borne infections: a case report. Front Cell Infect Microbiol 2024; 14:1194307. [PMID: 38343886 PMCID: PMC10853403 DOI: 10.3389/fcimb.2024.1194307] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2023] [Accepted: 01/10/2024] [Indexed: 02/15/2024] Open
Abstract
A 51-year-old male with a history of Cacchi-Ricci disease and long-standing infection with various species of Borrelia, Babesia, and Bartonella presented with recurrent symptoms of right-sided flank pain. Numerous renal calculi were identified on imaging. The etiology of the calculi had not been previously elucidated. Symptoms intermittently date back to 2002 when uric acid stones were identified. Subsequent calculi analysis revealed calcium oxalate stones. Despite the commonality of nephrolithiasis in patients with Cacchi-Ricci disease, the extreme number of calculi and recurrent presentation of symptoms persisted despite a plethora of medical evaluations, dietary changes, and hereditary testing. This case raises questions of etiology including possible immune deficiency and whether his uncommon microbial history contributes to recurrent stone formation.

Start-of-day oculomotor screening demonstrates the effects of fatigue and rest during a total immersion training program. Surgery 2023; 174:1193-1200. [PMID: 37640665 DOI: 10.1016/j.surg.2023.07.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Revised: 06/23/2023] [Accepted: 07/18/2023] [Indexed: 08/31/2023]
Abstract
BACKGROUND Investigating changes in sleep and fatigue metrics during intensive surgical and trauma skills training, this study explored the dynamic association between oculomotor metrics and fatigue. Specifically, alterations in these relations over extended stress exposure, the influence of time of day, and the impact of fatigue exposure on sleep metrics were examined. METHODS Thirty-nine military medical students participated in 6 days of immersion, hyper-realistic, and high-stress experiential casualty training. Participants completed surveys assessing the state of sleepiness with oculomotor tests performed each morning and evening, analyzing eye movement and pupillary change to characterize fatigue. Participants wore Fitbit TM devices to measure overall time asleep and time in each sleep stage during the training. RESULTS Fitbit data showed increased average minutes in rapid eye movement, deep sleep, and less time in light sleep from day 1 to day 4. The microsaccade peak velocity-to-displacement ratio exhibited a morning decrease but not in afternoon sessions, indicating repeated but temporary effects of accumulated fatigue. There were no findings regarding pupil reactivity to illumination changes. CONCLUSION This study describes characteristics of fatigue measured by rapid and individually calibrated oculomotor tests. It demonstrates oculomotor relationships to fatigue in start-of-day testing, providing a direction for timing for optimal fatigue testing. These data suggest that improved sleep could signal resilience to fatigue during afternoon testing. Further investigation with more participants and longer duration is warranted. A deeper understanding of the interrelationships between training, sleep, and fatigue could improve surgical and military fitness.

Cytokine fluctuation during acute stress is correlated to life trauma. J Trauma Acute Care Surg 2023; 95:535-541. [PMID: 37165473 PMCID: PMC10545070 DOI: 10.1097/ta.0000000000004006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2023] [Revised: 03/30/2023] [Accepted: 03/31/2023] [Indexed: 05/12/2023]
Abstract
BACKGROUND Multiple studies have demonstrated that human neurobiology and behavior are inextricably linked to the activity of our immune systems. Trauma is associated with a multitude of immune system changes; reflecting this, posttraumatic stress disorder (PTSD) is often comorbid with immune-related conditions such as autoimmune disorders. To further investigate this phenomenon, we tested our hypothesis that cytokine fluctuations during and after an acute stress response correlates with experienced life trauma. METHODS Using a prospective observational approach, this cohort study measured biomarker profiles in firefighter participants (n = 63), with 9 participants having prior PTSD diagnoses and 54 without prior PTSD diagnoses. In addition, life trauma scores were determined from all participants using the Life Events Checklist 5 (LEC-5) survey. Baseline salivary biomarker concentrations were determined, along with levels immediately before, immediately after, and 1 hour following a standardized stressful training event. Biomarkers measured using these salivary samples included 42 cytokines and 6 steroid and thyroid hormones. The concentrations of these markers were then correlated, using Pearson correlation coefficients, with the participants' LEC-5 scores. t Tests were also performed to compare cytokine values between the populations with and without prior PTSD diagnosis. RESULTS Included in the cytokine panel were interleukin (IL)-8, IL-10, IL-1B, GCSF, IL1-Ra, Groα, IFNa2, PDGFAA, and VEGF, all of which demonstrated positive correlation at various time points in individuals with increased severity of LEC-5 scores (and thus increased experienced life trauma). Concentrations of Groα, PDGFAA, IL1-Ra, IL-1a, Mip1a, IL-1a, IL-6, Mip1b, TNFα, and TGFα were also found to be significantly altered at various time points in participants with prior PTSD diagnoses, demonstrating some overlap with the LEC-5 Pearson correlations. CONCLUSION The results support our hypothesis and demonstrate that LEC-5 scores are indeed significantly correlated to cytokine concentrations and fluctuations surrounding a stress test. LEVEL OF EVIDENCE Diagnostic Tests or Criteria; Level IV.

Abstract
INTRODUCTION The Military Match is the residency matching system for medical students attending the Uniformed Services University of Health Sciences, and the students were funded by the Health Professions Scholarship Program through the U.S. Army, Air Force, and Navy. To evaluate and compare military residency programs, students use residency program websites. Often, the residency program's website serves as a key source, or the only point of reference, when considering residency options, especially during times when face-to-face interactions are limited.This report aims to provide a systematic evaluation of military residency programs and their websites. MATERIALS AND METHODS Utilizing a previously published website usability scoring system, military residency programs were categorized to objectively and quantitatively analyze their websites. Usability was divided into four categories for quantifiable analysis: accessibility, marketing, content quality, and technology. The methodology for this analysis was replicated from published reports that have examined healthcare website usability. Each website was analyzed and scored in four categories: accessibility, content quality, marketing, and technology. A "General Usability" score was calculated for each website using a composite of the key factors within the four categories. An overall score was generated utilizing the weighted percentage across all four categories. To address deficiencies of the original methodology, a secondary analysis was performed on the listed websites utilizing an automated methodology for website usability. RESULTS A comprehensive list of 125 Accreditation Council for Graduate Medical Education U.S. Military residency program websites was compiled. Of these, 96 programs and 106 websites were evaluated. The primary analysis employing usability methodology identified technology as the highest ranked category with a score of 0.749 (SD ± 0.039) (SE 0.005) (P < .05). Marketing and content quality were the lowest scoring categories with mean scores of 0.414 (SD ± 0.054) (SE 0.006) and 0.428 (SD ± 0.229) (SE 0.027), respectively (P < .05). There was no significant difference in overall usability rankings or scores among the 96 residency program websites across the three branches (P < .05).Secondary analysis with the new usability methodology demonstrated military residency websites to exhibit more external backlinking compared to internal backlinking (P < 0.05) and no social media backlinking to any of the 106 analyzed websites. When comparing the three services, the Army had significantly lower external backlinking ranking 43.4 (P < .05) and overall backlinking ranking 56.4 (P < 0.05) when compared to the Navy (mean 48.8 and 71.7, and 43.4). There were no other differences in backlinking rankings across the three branches. CONCLUSIONS Residency websites have become a primary way to communicate information to applicants. By assessing the overall usability of the various military residency websites, we determined the effectiveness of these websites to relay information to prospective students interested in applying for military residency. We predict that by improving website accessibility, residency programs increase their effectiveness at communicating information to potential applicants and increase interest in military residency programs.

A Geospatial Analysis of Severe Firearm Injuries Compared to Other Injury Mechanisms: Event Characteristics, Location, Timing, and Outcomes. Acad Emerg Med 2016; 23:554-65. [PMID: 26836571 DOI: 10.1111/acem.12930] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2015] [Revised: 12/04/2015] [Accepted: 12/06/2015] [Indexed: 11/30/2022]
Abstract
OBJECTIVES Relatively little is known about the context and location of firearm injury events. Using a prospective cohort of trauma patients, we describe and compare severe firearm injury events to other violent and nonviolent injury mechanisms regarding incident location, proximity to home, time of day, spatial clustering, and outcomes. METHODS This was a secondary analysis of a prospective cohort of injured children and adults with hypotension or Glasgow Coma Scale score ≤ 8, injured by one of four primary injury mechanisms (firearm, stabbing, assault, and motor vehicle collision [MVC]) who were transported by emergency medical services to a Level I or II trauma center in 10 regions of the United States and Canada from January 1, 2010, through June 30, 2011. We used descriptive statistics and geospatial analyses to compare the injury groups, distance from home, outcomes, and spatial clustering. RESULTS There were 2,079 persons available for analysis, including 506 (24.3%) firearm injuries, 297 (14.3%) stabbings, 339 (16.3%) assaults, and 950 (45.7%) MVCs. Firearm injuries resulted in the highest proportion of serious injuries (66.3%), early critical resources (75.3%), and in-hospital mortality (53.5%). Injury events occurring within 1 mile of a patient's home included 53.9% of stabbings, 49.2% of firearm events, 41.3% of assaults, and 20.0% of MVCs; the non-MVC events frequently occurred at home. While there was geospatial clustering, 94.4% of firearm events occurred outside of geographic clusters. CONCLUSIONS Severe firearm events tend to occur within a patient's own neighborhood, often at home, and generally outside of geospatial clusters. Public health efforts should focus on the home in all types of neighborhoods to reduce firearm violence.

Abstract
BACKGROUND The American College of Surgeons Committee on Trauma (ACSCOT) has developed and updated field trauma triage protocols for decades, yet the ability to identify major trauma patients remains unclear. We estimate the diagnostic value of the Field Triage Decision Scheme for identifying major trauma patients (Injury Severity Score [ISS] ≥ 16) in a large and diverse multisite cohort. STUDY DESIGN This was a retrospective cohort study of injured children and adults transported by 94 emergency medical services (EMS) agencies to 122 hospitals in 7 regions of the Western US from 2006 through 2008. Patients who met any of the field trauma triage criteria (per EMS personnel) were considered triage positive. Hospital outcomes measures were probabilistically linked to EMS records through trauma registries, state discharge data, and emergency department data. The primary outcome defining a "major trauma patient" was ISS ≥ 16. RESULTS There were 122,345 injured patients evaluated and transported by EMS over the 3-year period, 34.5% of whom met at least 1 triage criterion and 5.8% had ISS ≥ 16. The overall sensitivity and specificity of the criteria for identifying major trauma patients were 85.8% (95% CI 85.0% to 86.6%) and 68.7% (95% CI 68.4% to 68.9%), respectively. Triage sensitivity and specificity, respectively, differed by age: 84.1% and 66.4% (0 to 17 years); 89.5% and 64.3% (18 to 54 years); and 79.9% and 75.4% (≥55 years). Evaluating the diagnostic value of triage by hospital destination (transport to Level I/II trauma centers) did not substantially improve these findings. CONCLUSIONS The sensitivity of the Field Triage Decision Scheme for identifying major trauma patients is lower and specificity higher than previously described, particularly among elders.

Abstract
Multiple Sclerosis (MS) is an inflammatory disease that demyelinates the central nervous system causing progressive disability. The urodynamics of MS patients is an important consideration because these patients are susceptible to acute urinary bladder retention associated with a high fever. Treatment should include irrigation using a Foley catheter and an irrigation syringe to remove residual urine and sediment from the neurogenic bladder, intravenous fluid resuscitation, bacteriological analysis of the residual urine, and admission to an Intensive Care Unit for further evaluation by a urologist. After discharge, suprapubic cystostomy should be a consideration for patients who have chronic urinary tract infections associated with acute urinary bladder retention, as well as limited mobility to perform self catheterization, or limited personal care assistants trained to perform a urethral clean intermittent catheterization.

Abstract
Psoriasis is a papulosquamous skin disease that is recognized as one of the most common immune-mediated disorders. At least nine chromosomal psoriasis susceptibility loci have been identified. It is important to emphasize that management of psoriasis begins with identification of the extent of the cutaneous disease. There are three clinical forms of psoriasis, to include psoriasis vulgaris, pustular psoriasis, and erythrodermic psoriasis. Treatments currently available are topical agents used predominantly for mild disease and for recalcitrant lesions in more severe disease, phototherapy for moderate disease, and systemic agents, including photochemotherapy, oral agents, and newer injectable biological agents, which have revolutionized the management of severe psoriasis.

Abstract
STUDY OBJECTIVE The first hour after the onset of out-of-hospital traumatic injury is referred to as the "golden hour," yet the relationship between time and outcome remains unclear. We evaluate the association between emergency medical services (EMS) intervals and mortality among trauma patients with field-based physiologic abnormality. METHODS This was a secondary analysis of an out-of-hospital, prospective cohort registry of adult (aged > or =15 years) trauma patients transported by 146 EMS agencies to 51 Level I and II trauma hospitals in 10 sites across North America from December 1, 2005, through March 31, 2007. Inclusion criteria were systolic blood pressure less than or equal to 90 mm Hg, respiratory rate less than 10 or greater than 29 breaths/min, Glasgow Coma Scale score less than or equal to 12, or advanced airway intervention. The outcome was in-hospital mortality. We evaluated EMS intervals (activation, response, on-scene, transport, and total time) with logistic regression and 2-step instrumental variable models, adjusted for field-based confounders. RESULTS There were 3,656 trauma patients available for analysis, of whom 806 (22.0%) died. In multivariable analyses, there was no significant association between time and mortality for any EMS interval: activation (odds ratio [OR] 1.00; 95% confidence interval [CI] 0.95 to 1.05), response (OR 1.00; 95% CI 9.97 to 1.04), on-scene (OR 1.00; 95% CI 0.99 to 1.01), transport (OR 1.00; 95% CI 0.98 to 1.01), or total EMS time (OR 1.00; 95% CI 0.99 to 1.01). Subgroup and instrumental variable analyses did not qualitatively change these findings. CONCLUSION In this North American sample, there was no association between EMS intervals and mortality among injured patients with physiologic abnormality in the field.

Abstract
BACKGROUND During the last 25 years, scientific experimental and clinical studies have documented the dangers of cornstarch powder on examination and surgical gloves because the cornstarch promotes wound infection, causes serious peritoneal adhesions and granulomatous peritonitis, and is a well-documented vector of the latex allergy epidemic in the world. Realizing the dangers of cornstarch on examination and surgical gloves, Germany's regulations of personal protective equipment banned the use of surgical glove powder cornstarch in 1997. In 2000, the Purchasing and Supply agency for the United Kingdom ceased to purchase any gloves lubricated with cornstarch. DISCUSSION Realizing the dangers of cornstarch-powdered gloves, many hospitals and clinics in the United States have banned the use of cornstarch-powdered examination and surgical gloves. Hospitals that have banned cornstarch in their examination and surgical gloves have noted a marked reduction in the latex allergy epidemic in their facilities. Realizing the dangers of cornstarch-powdered examination and surgical gloves, Dr Sheila A. Murphey, branch chief, Infection Control Devices Branch, Division of Anesthesiology, General Hospital, Infection Control, and Dental Devices Office of Device Evaluation, Center for Devices and Radiological Health of the Food and Drug Administration (FDA), recommended that a Citizen's Petition be filed to the FDA to ban cornstarch on surgical and examination gloves. CONCLUSION The 12 authors of this report have attached the enclosed petition to the FDA to ban the use of cornstarch on all synthetic and latex examination and surgical gloves used in the United States.

Abstract
BACKGROUND Peanut allergies affect 1.5% of children. The majority of reactions to peanuts are mild, but peanut allergy is also the most common cause of fatal anaphylactic reactions to food. CASE REPORT The purpose of this case report was to describe a 1-year old boy who developed difficulty breathing after eating a peanut food product. The boy was taken immediately by his mother to an Emergency Department, exhibiting severe respiratory distress. After speaking to the child's mother, the emergency physician (EP) realized that the wheezing was due to a peanut food allergy. The child's respiratory symptoms responded within 10 min to bronchodilatator inhalation. The EP gave the mother educational information regarding the management of asthma and the proper use of metered dose inhalers with spacer devices. The EP referred the child to a clinical allergist who specializes in the management of food allergies. The diagnosis was made by skin prick testing as well as in vitro measurement of peanut-specific immunoglobulin E. CONCLUSION The allergist explained that the mainstay of management of peanut allergy is avoidance of the allergenic food. Patient education involved teaching the mother to avoid high-risk situations such as dinner with family members who are not informed about the child's allergy to peanuts, encouraging the child to wear a Medic Alert Bracelet, and teaching the family and child to recognize early symptoms of allergic reactions and to manage an anaphylactic reaction, including the use of self-injectable epinephrine, as well as activating emergency services.

Need for informed consent for dentists who use mercury amalgam restorative material as well as technical considerations in removal of dental amalgam restorations. J Environ Pathol Toxicol Oncol 2008; 26:305-22.

Abstract
Amalgam restorative material generally contains 50% mercury (Hg) in a complex mixture of copper, tin, silver, and zinc. It has been well documented that this mixture continually emits mercury vapor, which is dramatically increased by chewing, eating, brushing, and drinking hot liquids. Mercury has been demonstrated to have damaging effects on the kidney, central nervous system, and cardiovascular system, and has been implicated in gingival tattoos. While mercury amalgams may result in detrimental exposure to the patient, they can also be a danger in dental practices. In Europe, the federal governments of Norway, Finland, Denmark, and Sweden have enacted legislation requiring that dental patients receive informed consent information about the dental restorative material that will be used. In the United States, a few state governments have enacted informed consent legislation for dental patients receiving dental restorations. These state legislations were enacted by Maine, California, Connecticut, and Vermont. It is a sad tragedy that mercury is causing such health damage to many people. The American Dental Association has said for the past 150 years that the mercury in amalgam is safe and does not leak; however, no clinical studies were ever done and the Food and Drug Administration approved amalgam under a grandfather clause. Subsequent studies have shown this claim of safety not to be true. Over ten years ago, the Federation of American Societies for Experimental Biology Journal published a comprehensive article calling mercury restorative material a major source of mercury exposure to the U.S. population. The authors of this paper recommend that federal and state legislation be passed throughout our country to ensure that consent forms are given to patients receiving silver-mercury amalgam restorative material.

Abstract
'Organic' is a labelling term that denotes products produced under the authority of the Organic Foods Production Act. Before a product can be labelled 'organic', a government-approved certifier inspects the farm where the food is grown to make sure the farmer is following all the rules necessary to meet the US Department of Agriculture (USDA) organic standards. Companies that handle or process organic food before it gets to your local supermarket or restaurant must be certified, too. Along with the national organic standards, the USDA developed strict labelling rules to help consumers know the exact content of the food they buy. It is important to emphasise that the USDA has not made any health claims for organic foods. It is indeed fortunate that the US Department of Health and Human Services, Centers for Disease Control and Prevention, USDA and the Environmental Protection Agency are now expanding their research to explore the scientific basis for the health benefits of organic foods.

Abstract
The National Childhood Vaccine Injury Act of 1986, as amended, established the Vaccine Injury Compensation Program (VICP). The VICP went into effect on October 1, 1988 and is a Federal "no-fault" system designed to compensate individuals, or families of individuals, who have been injured by covered vaccines. From 1988 until July 2006, a total of 2531 non-autism/thimerosal and 5030 autism/thimerosal claims were made to the VICP. The compensation paid for the non-autism/thimerosal claims from 1988 until 2006 was $902,519,103.37 for 2542 awards. There was no compensation for any of the autism/thimerosal claims. On the basis of the deaths and extensive suffering to patients and families from the adverse reactions to vaccines, all physicians must provide detailed information in the Vaccine Information Statement to the patient or the parent or legal guardian of the child about the potential dangers of vaccines as well as the VICP.

Abstract
Because many physicians do not use the Vaccine Information Statement (VIS), we created a revised statement that would alert the physician to the need to use the VIS. Even though the Centers for Disease Control (CDC) coordinated this evaluation, both the CDC and most of the State Board of Medical Examiners did not support this revision of the VIS. Despite the disinterest of the vast majority of the State Board of Medical Examiners, we would recommend that this updated VIS be implemented immediately to educate our society on the information in the VIS.

Abstract
The occurrence of pressure ulcers in patients is very high in certain high-risk groups. These special high-risk groups include elderly patients, patients with spinal cord injuries, or any individual with an impaired ability to reposition. Prevention of pressure ulcers is by far the best treatment of this condition, warranting certain interventions and preventive measures. One major risk factor to be minimized is the exposure of skin to moisture. Underpads are often used to protect the skin of patients who are incontinent. These products effectively absorb moisture and present a quick-drying surface to the skin. The construction of an underpad should accomplish three goals. First, its backing should have a low coefficient of friction to prevent frictional skin injuries. Second, an inner absorbent core should rapidly contain moisture and disseminate it throughout the entire pad. Third, the core and coverstock should successfully work together to retain moisture and prevent wet-back or fluid return. The purpose of this study was to determine the performance of three commercially available underpads in reducing the development of pressure sores in patients at high risk. In this study we selected three underpads that could be securely attached to either the underlying bed or the chair. The three performance parameters examined were absorbent capacity, wetback prevention, and holding security of the underpads. Measurements of these performance parameters can be easily replicated in other laboratories. The results of these studies provide a scientific basis for selecting and purchasing an underpad to prevent pressure ulcers in patients. In this comprehensive evaluation, we assess an absorbent underpad with polyethylene flaps and two absorbent underpads with adhesive. The absorbent capacity results showed Tranquility SlimLine Peach Sheet to be the most absorbent. The wet-back results showed Tranquility SlimLine Peach Sheet to be the only underpad with no wet-back, with no fluid returning through the coverstock. The Tranquility SlimLine Peach Sheet Underpad has four adhesive strips attached to each of the four ends of the underpad surface. These 5 cm long strips secure well to the seat of a wheelchair or chair. In contrast, they do not maintain secure attachment to a bed sheet, making the bed sheet vulnerable to urine or stool penetration. When the clinical staff used the Tuckable on the bed surface, they were all impressed by the secure fit of the plastic wings, which easily tucked around the mattress. The wings remained in place throughout the night. Realizing the stability of the Tuckable underpads, the clinical staff suggested that the Tuckable underpad be placed first on the bed, then the Tranquility SlimLine Peach Sheet can be placed on top of the Tuckable underpad, using the four adhesive strips to attach it to the surface of the Tuckable underpad. All of the staff were impressed that the adhesive strips remained securely attached to the Tuckable. This clinical decision was found to be very cost efficient, because the Tuckable could remain in place more than a week without changing. Even though we have developed a unique scientific basis for the selection of underpads for use on either chairs or beds, it can be a financial challenge to the patient or healthcare setting to use these products, because Medicare provides no reimbursement for underpads, an invitation to pressure ulcer formation. In the absence of responsible federal government policy, we are making recommendations for the selection of a cost-conscious and responsible company that sells incontinence products--Home Deliver Incontinent Supplies Co., Inc., (HDIS), Olivette, Missouri.

Abstract
Syneture (division of U.S. Surgical, division of Tyco Healthcare, Norwalk, Connecticut, USA) STEEL sutures are monofilament stainless steel sutures composed of 316L stainless steel conforming to ASTM Standard F138 grade 2 (" Stainless steel bar and wire for surgical implant"). STEEL sutures meet all requirements established by the United States Pharmacopeia (USP) for nonabsorbable surgical sutures. Steel sutures are for use in abdominal wound closure, intestinal anastomosis, hernia repair, sternal closure, and skin closure. They are attached to the following types of surgical needles: Roto-Grip Needles and SCC Needle. The sutures and needles are packaged in a Mylar/Tyvek outer envelope. The purposes of this clinical review are two fold. First, we will report the performance of the Syneture STEEL suture product in the largest studies of suture performance ever reported in the literature. In addition, we will provide comprehensive information from the surgical literature that highlights the unique benefits of stainless steel sutures for the following wound closure techniques: sternal fixation, abdominal wound repair, inguinal hernia repair, and skin wound closure. Consorta Inc. (Rolling Meadows, Illinois), a leading healthcare resource management group purchasing organization, and Syneture, jointly with a clinician task force, designed a reproducible surgical evaluation program for needles and sutures in a large cooperative of healthcare systems. Because of the subjective nature of the more commonly used suture selection techniques, a nonexperimental observational study approach was designed to replace perception of performance characteristics with actual clinical experience. In a report involving 19 Consorta shareholder hospitals, they discussed the preliminary part (Phase I) of a large nonexperimental observational study of the clinical performance of surgical needles and sutures. Performance characteristics of the sutures and needles produced by Syneture that were evaluated in 3407 surgical procedures included packaging/ease of opening, needle strength and sharpness, tissue drag, knot security, tensile strength, clinically acceptable determinations, and clinically unacceptable determinations. In this preliminary study, the surgeons concluded that the needles and sutures were clinically acceptable in 98.1% of the evaluations. Armed with this favorable experience, we wanted to expand this observational study to an entirely new group of shareholder hospitals that had a larger number of participating hospitals (Phase I, 19 hospitals; Phase II, 42 hospitals). This more than doubling of hospital observational base dramatically increased the number of patients and performance evaluations. In the Phase II expanded program involving 42 hospitals, the number of patients (8939) and the number of evaluations (25,545) were more than twofold the preliminary study. In the phase I multicentric evaluation of Syneture surgical sutures, the performance of 9266 sutures was evaluated. Of these performance evaluations, 130 evaluations focused on Syneture STEEL sutures. The surgeons were especially pleased by the performance of this suture product, with 129 Syneture STEEL products being judged as clinically acceptable in their performance. Only one Syneture STEEL suture was judged to be unacceptable in its performance, resulting in a 99.2% acceptability rating. In the expanded phase II evaluation of Syneture suture products, the performance evaluation involved 25,545 surgical suture evaluations. The performance of Syneture STEEL sutures was judged in 215 cases. Of these product performance evaluations, 207 were judged to be clinically acceptable in their performance (96.3%). It is important to emphasize that the phase I and phase II observational studies evaluated the performance of other sutures besides monofilament steel sutures. These comprehensive suture and needle performance evaluations included the following additional sutures: Plain Gut, Mild Chromic Gut, Chromic Gut, DEXON II, DEXON S, MAXON, BIOSYN, SOFSILK, SURGILON, BRALON, MONOSOF, DERMALON, SURGIDAC, POLY-SORB, TI.CRON, SURGIPRO, SURGIPRO II, NOVAFIL, VASCUFIL, and FLEXON. Finally, we provide a collective review of the literature that shows the reliable performance of monofilament stainless steel sutures in the following wound closure techniques: sternal fixation, abdominal wound closure, inguinal hernia repair, and skin wound closure.

Abstract
Rubella, also known as German measles, is usually a very mild infection that can have devastating effects in certain instances. It is a pleomorphic RNA virus in the Togaviridae family of the genus Rubivirus. It typically causes a scarletiniform rash, cervical lymphadenopathy, and mild constitutional symptoms, but in older children and adults, especially women, it may be more severe, with joint involvement and purpuric rash. Infection during the first 12 weeks of pregnancy results in congenital infection and/or miscarriage in 80-90% of cases. The congenital rubella syndrome (CRS) involves multiple organ systems and has a long period of active infection and virus shedding in the postnatal period. For these reasons, the rubella vaccine program was instituted in 1969, and the incidence of rubella infection in the United States has since declined by 99%. Rubella has been recognized as a disease for approximately 200 years, and it has since been found that humans are the only natural reservoir for the rubella virus. Virus is present in nasopharyngeal secretions, blood, feces, and urine during the clinical illness, although patients with subclinical disease are also infectious. The virus is spread via oral droplets and is shed in the nasopharynx for approximately 7 days before and after the rash is visible. CRS includes a configuration of anomalies, including nerve deafness, cataracts, cardiac anomalies (usually pulmonary artery and valvular stenosis, and patent ductus arteriosis), and mental retardation, with late complications including diabetes, thyroid disease, growth hormone deficiency, and progressive panencephalitis. In 1969, the first rubella vaccine was licensed for use, and the Centers for Disease Control and Prevention (CDC) began its National Congenital Rubella Syndrome Registry. As required under the National Childhood Injury Act, all healthcare providers in the United States who administer any vaccine shall, prior to administration of the vaccine, provide a copy of the Vaccine Information Statements (VIS) produced by the CDC to the parent or legal representative of any child to whom the provider intends to administer such vaccine, or to any adult to whom the provider intends to administer such vaccine. Despite efforts to vaccinate children, CRS continues to occur in the United States. Hispanic infants have an increased risk of CRS. HIV-1infected children with a preserved immune system and MMR immunization had a good response to rubella vaccine. In contrast, those in more advanced categories for HIV infection responded poorly. Issues of risk, choice, and chance are central to the controversy over the MMR vaccine that erupted in the UK in 1998, and has continued into the new millennium. An important contribution to the MMR controversy has come from the parents of autistic children, some of whom reject the notion that this disorder is a random genetic misfortune and insist that it is, at least in part, the result of some environmental insult, such as MMR vaccinations.

Abstract
The purpose of this collective review is to describe revolutionary advances in the treatment of Gardner's syndrome (GS), pseudofolliculitis barbae, nasal septal perforation, factitious wounds, and hidradenitis suppurativa (HS). Gardner's syndrome or familial polyposis has various manifestations that appear to be controlled by a single genetic locus. Apart from the large bowel adenomas, which are always present, a common extracolonic symptom of Gardner's syndrome is the occurrence of epidermal cysts. These cysts can be seen before the intestinal polyps are evident. Because epidermal cysts in patients with Gardner's syndrome are always benign, we excise these cysts using incisions that are commonly used for rhytidectomy. Pseudofolliculitis barbae, a pseudofolliculitis caused by ingrown hairs, effects 85% of blacks who shave their beards. When this disease is allowed to progress to keloid formation, we use a surgical approach that includes excision of the keloidal scar, meticulous debridement of all residual ingrown hairs in the underlying wound, and coverage of the defect with a split-thickness skin graft. More recently, laser therapy has revolutionized the treatment of pseudofolliculitis barbae and has enabled a cure for the first time for those plagued with this disorder and for whom a beardless face is acceptable. Nasal septal perforation is a well recognized complication of septal surgery. Other iatrogenic causes of perforation include cryosurgery, electrocoagulation for epitaxis, nasotracheal intubation, or nose packing. In recent years drugs such as cocaine account for an increasing number of perforations. It has only been with the use of an external approach for the repair of the nasal septal defect that surgical closure has become easier and more reliable. The external approach allows for greater surgical closure and enables the surgeon to use both hands with the aid of binocular vision to mobilize and suture local mucosal advancement flaps and the intraseptal connective tissue grafts. More recently, surgeons have repaired large septal perforations with a radial forearm free flap. Because of its availability and deep emotional significance, the skin is a common site for self-destructive behavior with the development of factitious skin wounds. When suspected, psychiatric care must proceed immediately. Second, the ulcer can then be healed by appropriate techniques and wound repair. It is important to emphasize that the treating physician must first confront the patient, and then a psychiatrist should provide appropriate psychotherapy. Hidradenitis suppurativa is an inflammatory disease of the skin and subcutaneous tissue that occurs in apocrine-gland-bearing areas distributed in the axilla, mammary nipple areola, mons pubis, groin, scrotum, perineum, perianal region, and umbilicus. The condition has an insidious onset. The susceptibility of women's axillary skin to hidradenitis suppurativa may be related, in part, to the practice of axillary removal of hair with a safety razor. Consequently, the use of safety razors must be avoided and replaced with the use of an electric razor. The method of treatment will vary with the stage of the disease. Treatment of the chronic stage of axillary hidradenitis suppurativa is primarily surgical. More recently, carbon dioxide laser treatment, with healing by secondary intention, is proving to be a rapid, efficient, and economic treatment of this difficult wound.

Abstract
On February 12, 2002, the US Environmental Protection Agency (EPA) announced a voluntary decision by industry to move consumer use of treated lumber products away from a variety of pressure-treated wood that contains Arsenate (As) by December 31, 2003, in favor of new alternative wood preservatives. It is the purpose of this report to outline legislative efforts to ban the use of chromated copper arsenate (CCA)-treated wood for residential roofing in the State of Oregon. At the time that the legislation was introduced, it was coincidental that the National Roofing Contractors Association (NRCA) recommended that CCA-treated wood should not be used in residential roofing. A summary of the report is included in this review. Finally, we discuss some of the potentially harmful environmental hazards of wood preservatives on the environment. In addition to the toxicity of pressure-treated wood on our environment, we point out that wood as well as pressure-treated wood assemblies are highly flammable. Consequently, we recommend the use of residential roofing systems that have Class A fire protection for the homeowner. Because residential roof fires remain a life-threatening danger to residential homeowners in the United States, we describe a national fire prevention program for reducing residential roof fires by use of an Underwriters Laboratories Inc. (UL) and National Fire Protection Association Class A fire-rated roof system.

Abstract
Chemical injuries are commonly encountered following exposure to acids and alkali, including hydrofluoric acid, formic acid, anhydrous ammonia, cement, and phenol. Other specific agents that cause chemical burns include white phosphorus, elemental metals, nitrates, hydrocarbons, and tar. Even though there are more than 65,000 chemicals available on the market, and an estimated 60,000 new chemicals produced each year, the potential deleterious effects of these chemicals on humans are still unknown. The Superfund Amendments and Reauthorization Act contains extensive provisions for emergency planning and the rights of communities to know about toxic chemical releases. Since 1990, the Agency for Toxic Substances and Disease Registry (ATSDR) has maintained an active, state-based Hazardous Substances Emergency Events Surveillance (HSEES) system to describe the public health consequences risked by access to hazardous chemicals. Most chemical agents damage the skin by producing a chemical reaction rather than hyperthermic injury. Although some chemicals produce considerable heat as a result of an exothermic reaction when they come in contact with water, their ability to produce direct chemical changes on the skin accounts for the most skin injury. Specific chemical changes depend on the agent, including acids, alkalis, corrosives, oxidizing and reducing agents, desiccants, vesicants, and protoplasmic poisons. The concentration of toxic agent and duration of its contact primarily determine degree of skin destruction. Hazardous materials (hazmats) are substances that may injure life and damage the environment if improperly handled. HAZMAT accidents are particularly dangerous for responding personnel, who are in danger from the moment of arrival on the scene until containment of the accident. Consequently, the Superfund Amendment and Reauthorization Act mandates community preparedness for dealing with hazmat accidents. Paramedics and members of the hazmat response team (usually firefighters) must work together to identify toxic chemicals and assess hazardous environments. The contingency plan for hazmat management can be divided into two parts: initiation of the site plan and evacuation. In coping with hazmat incidents, two distinct goals must be achieved concomitantly. First, hazmats must be contained, fire and explosions must be extinguished, and the site eventually must be cleaned. Second, those exposed to hazmats must be treated at the scene of contamination as well as in the hospital and rehabilitation setting.

Devastating Injuries in Healthcare Workers: Description of the Crisis and Legislative Solution to the Epidemic of Back Injury from Patient Lifting. J Long Term Eff Med Implants 2005; 15:225-41.

Abstract
The purpose of this report is to describe a crisis in healthcare, disabling back injuries in US healthcare workers. In addition, outlined is the proven solution of safe, mechanized, patient lifting, which has been shown to prevent these injuries. A "Safe Patient Handling--No Manual Lift" policy must be immediately instituted throughout this country. Such a policy is essential to halt hazardous manual patient lifting, which promotes needless disability and loss of healthcare workers, pain and risk of severe injury to patients, and tremendous waste of financial resources to employers and workers' compensation insurance carriers. Healthcare workers consistently rank among top occupations with disabling back injuries, primarily from manually lifting patients. Back injury may be the single largest contributor to the nursing shortage. Reported injuries to certified nursing assistants are three to four times that of registered nurses. A national healthcare policy for "Safe Patient Handling--No Manual Lift" is urgently needed to address this crisis. Body mechanics training is ineffective in prevention of back injury with patient lifting. Mandated use of mechanical patient lift equipment has proven to prevent most back injury to nursing personnel and reduce pain and injury to patients associated with manual lifting. With the national epidemic of morbid obesity in our country, innovative devices are available for use in emergency medical systems and hospitals for patient lifting and transfer without injury to hospital personnel. The US healthcare industry has not voluntarily taken measures necessary to reduce patient handling injury by use of mechanical lift devices. US healthcare workers who suffer disabling work-related back injuries are limited to the fixed, and often inadequate, relief which they may obtain from workers' compensation. Under workers' compensation law, healthcare workers injured lifting patients may not sue their employer for not providing mechanical lift equipment. Discarding healthcare workers disabled by preventable back injuries is an abuse which legislators must remedy. In addition, Medicare reimbursement policies must also be updated to allow the disabled community to purchase electrically operated overhead ceiling lifts. The US lags far behind countries with legislated manual handling regulations and "No Lifting" nursing policies. England and Australia have had "No Lifting" nursing policies in place since 1996 and 1998, respectively. The National Occupational Research Agenda (NORA) recognized a model in 2003 for reduction of back injuries to nursing staff in US healthcare facilities. Also in 2003, the American Nurses Association called for elimination of manual patient handling because it is unsafe and causes musculoskeletal injuries to nurses. The first state legislation for safe patient handling passed both houses in California but was vetoed by the Governor in September 2004. California and other states are preparing to (re)introduce legislation in January 2005. A national, industry-specific policy is essential to quell the outflow of nursing personnel to disability from manual patient lifting.

Abstract
The use of powder-free natural rubber or latex-free emergency medical examination gloves is especially important to emergency medical technicians, paramedics, firefighters, and emergency department personnel to avoid eliciting an allergic reaction in the latex sensitized patient. The majority of our emergency medical technicians, paramedics, and firefighters are now wearing powder-free emergency medical examination gloves that comply with the stringent codes and standards established by the National Fire Protection Association (NFPA), while very few hospital emergency department personnel have been provided with NFPA-approved gloves. There are four well-defined goals of this report that will assist emergency medical services, fire departments, and hospitals in the selection and purchase of emergency medical examination gloves. First, we will review again the stringent regulations for emergency medical examination gloves that are outlined by the NFPA. This design and performance standard was devised by the NFPA to address protective clothing for emergency medical operations. The design and performance requirement of the emergency medical examination gloves were described in the NFPA 1999, Standard on Protective Clothing for Emergency Medical Operations, 1997 Edition. As of September 2003, the emergency medical examination glove must meet the new design and performance requirements of emergency medical examination gloves discussed in NFPA 1999, Standard on Protective Clothing for Emergency Medical Operations, 2003 Edition.

Abstract
The purpose of this report is to provide further information about vaccine information statements (VISs) that are revolutionary but neglected educational advances in the United States. Because the use of VISs is mandated by the Federal Government in every individual being immunized, it is the goal of this report to further awaken health professionals and society to the mandatory use of these superb educational statements. With the passage of the National Childhood Vaccine Injury Act of 1986, the Federal Government required that VISs would be given to all vaccine recipients. As of September 2001, the VISs that must be used are diphtheria, tetanus, pertussis, (DTaP); diphtheria, tetanus (Td); measles, mumps, rubella (MMR); polio (IPV); hepatitis B; Haemophilus influenzae type b (Hib); varicella; and pneumococcal conjugate. Copies of the VISs are available at www.cdc.gov/nip/publications/VIS. The National Childhood Vaccine Injury Act of 1986 mandated that all health care providers report certain adverse events that occur following vaccination. As a result, the Vaccine Adverse Events Reporting System (VAERS) was established by the FDA and the Centers for Disease Control and Prevention (CDC) in 1990. In order to reduce the liability of manufacturers and healthcare providers, the National Childhood Vaccine Injury Act of 1986 established the National Vaccine Injury Compensation Program (NVICP). This program is intended to compensate those individuals who have been injured by vaccines on a no-fault basis. While the use of VISs has been mandated since 1996, a national survey of private practice office settings has revealed that many immunized patients do not receive the VISs. When these forms were used, physicians rarely initiated discussions regarding contraindications to immunizations or the National Vaccine Injury Compensation Program. Fortunately, the state boards of medical examiners, like the one in Oregon, are taking a strong stand for the use of VISs, with the warning that failure to use a VIS may result in disciplinary action. Our nation and practicing physicians must be awakened to the importance of the use of VISs to ensure that every vaccinated individual receives this statement at the time of vaccination.

Abstract
Errors resulting in adverse events in the medical care system are ubiquitous and underreported. Critical incident techniques that have been used to reduce errors in aviation have recently been applied to evaluate adverse events in the critical care arena. We report an evaluation of interrater agreement on responses to questions concerning adverse event reporting using a computer-based medical incident reporting system (MIRS). Thirty-four intensive care unit staff volunteers reviewed five fabricated test cases containing iatrogenic factors, then completed an incident report for each case using the MIRS. Interrater agreement was significant for all five cases (p < 0.01). The time required to complete a report decreased significantly from the first case to the last (p < 0.01). Overall, the MIRS was perceived as a relatively quick (< 6 minutes) and comprehensive reporting tool. The results indicate that health care providers report adverse events similarly, suggesting that the MIRS would be a useful tool in the reduction of errors (as a process improvement program) and to facilitate the continuing process of health care improvement.

Abstract
OBJECTIVE To determine whether the administration of recombinant human erythropoietin (rHuEPO) to critically ill patients in the intensive care unit (ICU) would reduce the number of red blood cell (RBC) transfusions required. DESIGN A prospective, randomized, double-blind, placebo-controlled, multicenter trial. SETTING ICUs at three academic tertiary care medical centers. PATIENTS A total of 160 patients who were admitted to the ICU and met the eligibility criteria were enrolled in the study (80 into the rHuEPO group; 80 into the placebo group). INTERVENTIONS Patients were randomized to receive either rHuEPO or placebo. The study drug (300 units/kg of rHuEPO or placebo) was administered by subcutaneous injection beginning ICU day 3 and continuing daily for a total of 5 days (until ICU day 7). The subsequent dosing schedule was every other day to achieve a hematocrit (Hct) concentration of >38%. The study drug was given for a minimum of 2 wks or until ICU discharge (for subjects with ICU lengths of stay >2 wks) up to a total of 6 wks (42 days) postrandomization. MEASUREMENTS AND MAIN RESULTS The cumulative number of units of RBCs transfused was significantly less in the rHuEPO group than in the placebo group (p<.002, Kolmogorov-Smirnov test). The rHuEPO group was transfused with a total of 166 units of RBCs vs. 305 units of RBCs transfused in the placebo group. The final Hct concentration of the rHuEPO patients was significantly greater than the final Hct concentration of placebo patients (35.1+/-5.6 vs. 31.6+/-4.1; p<.01, respectively). A total of 45% of patients in the rHuEPO group received a blood transfusion between days 8 and 42 or died before study day 42 compared with 55% of patients in the placebo group (relative risk, 0.8; 95% confidence interval, 0.6, 1.1). There were no significant differences between the two groups either in mortality or in the frequency of adverse events. CONCLUSIONS The administration of rHuEPO to critically ill patients is effective in raising their Hct concentrations and in reducing the total number of units of RBCs they require.

Abstract
OBJECTIVE To determine whether admission source is a potential risk factor for appendiceal rupture. METHODS Administrative data were obtained from the California Office of Statewide Health Planning and Development for all patients in San Diego County with the primary diagnosis of appendicitis during 1993. The appendiceal rupture ratio was defined as those coded as ruptured (ICD-9-CM codes 540.0 and 540.1) divided by both ruptured and non-ruptured cases (540.9). The odds ratio of appendiceal rupture from routine outpatient office or clinic venues vs those admitted through the ED were calculated using multivariate logistic regression analysis to adjust for age, sex, race, comorbidity, insurance status, and home address to hospital proximity. RESULTS There were a total of 1,906 patients, of whom 663 (34.8%) had appendiceal ruptures. Of the 1,360 (71.4%) admitted from the ED, 422 (31.0%) had ruptures, compared with 211 (43.3%) of the 487 admitted from outpatient sources (p < 0.0001). Patients with appendicitis directly admitted from outpatient sources were more likely to be complicated by appendiceal rupture than were those admitted through the hospital ED (adjusted odds ratio 1.62, 95% CI = 1.28 to 2.05, p < 0.0001). CONCLUSION Patients with appendicitis admitted from outpatient sources are more likely to have appendiceal rupture than are those admitted from the ED.

Abstract
OBJECTIVE To evaluate the long-term survival and factors that influence survival among a cohort of elderly trauma patients compared with an uninjured cohort. DESIGN A retrospective cohort analysis. DATA SOURCES Health Care Finance Administration, Baltimore, Md, Medicare data. SUBJECTS A cohort of elderly patients (n = 9424) hospitalized for injury in 1987 was identified using Medicare hospital discharge abstract data. An uninjured comparison group (n = 37,787) was identified from Medicare eligibility files. For injured patients, an Injury Severity Score was generated from the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9CM) codes. For both cohorts, preexisting illness was assessed by ICD-9CM codes from Health Care Finance Administration outpatient and inpatient data files for 1986 and 1987. MAIN OUTCOME MEASURES Relative risk for mortality within 5 years subsequent to injury, adjusted for age, sex, and preexisting illness, using Cox proportional hazard regression. RESULTS The injured cohort had a significantly reduced 5-year survival when compared with the uninjured group (relative risk [RR] = 1.71; 95% confidence interval, 1.66-1.77). The lower survival persisted even among patients who survived at least 3 years after injury. Coexisting disease, age, and Injury Severity Score were strong predictors of survival. CONCLUSIONS The adverse effect of trauma on survival in elderly patients is not isolated to the immediate postinjury period, but lasts years after the trauma episode. Further study is required to identify the reasons for this persistent effect of trauma on subsequent survival.

Abstract
BACKGROUND The incidence of recurrent trauma in the elderly is unknown. This study evaluated the risk of readmission for injury among elderly trauma patients compared with an uninjured geriatric cohort. The effects of age, sex, race, preexisting illness, and ISS on trauma recidivism were determined. METHODS Population based retrospective cohort analysis of the elderly using administrative data from the Health Care Financing Administration was performed. The measured outcome was trauma admission within 5 years. The injured were identified using hospital discharge data and the Injury Severity Score generated by ICD-Map. The uninjured were identified from Medicare eligibility files. Comorbid illness was assessed using ICD-9CM codes from outpatient and inpatient data files. RESULTS The injured members of the cohort had increased risk of subsequent new trauma admission (p < 0.001). Increasing Injury Severity Score, age, and comorbid illness are associated with trauma recidivism. CONCLUSION Trauma in the elderly is recurrent. Further study is required to develop age and injury specific interventions to prevent recurrent injury.

Abstract
BACKGROUND The use of needle-localization breast biopsy (NLBB) for the early diagnosis of breast cancer is common. The therapeutic adequacy of tumor-free margins following NLBB is unknown. We hypothesized that the presence of residual tumor after reexcision (mastectomy, tylectomy, or quadrantectomy) does not depend on the margin status following NLBB. PATIENTS AND METHODS Retrospective cohort analysis was performed on 890 consecutive NLBBs executed between January 1990 and June 1994. Patients with invasive breast neoplasia were divided into two groups based on the tumor margins after NLBB. Group 1 were the women with positive margins, and group 2 had negative margins. Breast specimens after reexcision were reviewed for evidence of residual invasive carcinoma. RESULTS Invasive neoplasia was present in 107 patients (12%). Surgical margins and definitive records of care were available for 96 of them (90%). All 45 patients in group 1 and 38 (75%) of 51 patients in group 2 underwent reexcision of the initial biopsy site (P = 0.36). Residual invasive carcinoma was present in 10 patients (22%) in group 1 and 3 (8%) in group 2 (P = 0.13). CONCLUSION Invasive breast neoplasia diagnosed by NLBB requires reexcision regardless of tumor margins to achieve complete local surgical eradication of tumor.

Abstract
OBJECTIVE Recent evidence suggests that patients with a normal cranial CT scan after head injury can be safely discharged home from the emergency department. However, supporting data from previous studies has relied on incomplete patient follow-up. We utilized a statewide comprehensive hospital abstract reporting system (CHARS) to assess whether children with normal CT scans after head injury subsequently developed intracranial sequelae in the month following their initial injury. DESIGN Retrospective case-series study, with comprehensive statewide follow-up for 1 month. SETTING The emergency department of a Level 1 Trauma Center in Seattle, Washington. PARTICIPANTS All children (n = 400) with head injury, Glasgow Coma Score of 13 to 15, and initial normal CT scan seen over a 4.5-year time period. All were matched against CHARS to evaluate admissions within 30 days after emergency department disposition. For readmissions, International Classification of Diseases (9th revision) discharge and procedure information was collected. All children were also matched against the state death files. RESULTS Four children were readmitted for neurologic reasons within 1 month following injury. One child on coumadin for heart disease developed a symptomatic subdural hematoma 5 days after head injury, requiring neurosurgical drainage. One child developed a symptomatic hemorrhagic contusion 3 days after injury, requiring observation only. Two children were readmitted 1 day after injury for concussive symptoms; both were discharged home after observation only. There were no deaths among the study population. CONCLUSIONS Among children with a normal cranial CT scan after mild head injury, delayed intracranial sequelae requiring intervention are extremely uncommon. In otherwise stable patients, a normal cranial CT scan can identify patients to be safely discharged from the emergency department, and would be more cost-effective than 1 to 2 days of hospital observation.

Abstract
UNLABELLED The control of hemorrhage in hypothermic patients with platelet and clotting factor depletion is often impossible. Determining the cause of coagulopathic bleeding (CB) will enable physicians to appropriately focus on rewarming, clotting factor repletion, or both. OBJECTIVE To determine the contribution of hypothermia in producing CB and ascertain if simultaneous hypothermia and dilutional coagulopathy (DC) interact synergistically. METHOD Prothrombin time, partial thromboplastin time, and platelet function were determined at assay temperatures of 29 degrees to 37 degrees C on normal and critically ill, noncoagulopathic (NC) individuals. Dilutional coagulopathy was created using buffered saline and the assays repeated. RESULTS Hypothermic assay at < or = 35 degrees C significantly prolonged coagulation times. The effect of hypothermia on NC and DC samples was not different. CONCLUSION Assays performed at 37 degrees C underestimate coagulopathy in hypothermic patients. The effect of hypothermia on NC and DC is not different, indicating the lack of a synergistic effect. Normalization of clotting requires both rewarming and clotting factor repletion.

Abstract
OBJECTIVE To determine the accuracy of diagnostic peritoneal lavage (DPL) for the evaluation of intraabdominal injury in patients with a pelvic fracture as a result of blunt trauma. DESIGN Retrospective cohort analysis. SETTING Level I trauma center in metropolitan Seattle, Wash. PATIENTS Four hundred ninety-seven consecutive patients admitted with pelvic fractures following blunt trauma during a 60-month period. OUTCOME MEASURES Positive results of DPL, defined by one of the following: an immediate aspiration of more than 10 mL of gross blood; a red blood cell count of more than 0.0001 x 10(12)/L; a white blood cell count greater than 0.0005 x 10(9)/L; an elevated amylase, bilirubin, or creatinine level; or organic particles or bacteria in the effluent returned after installation of 1 L of crystalloid fluid lavaged in the peritoneal cavity. RESULTS Two hundred eighty-six patients underwent DPL. For 80 patients (28.0%), results of DPL were positive and for 194 patients (67.8%) the results of DPL were negative. For two patients (0.7%), results of DPL were false positive for a sensitivity of 94%. For another two patients (0.7%), the results of DPL were false negative for a specificity of 99%. As a diagnostic modality, DPL has a positive predictive value of 98% and a negative predictive value of 97%. CONCLUSIONS Diagnostic peritoneal lavage is a reliable method for the evaluation of intra-abdominal injury and should remain a standard component in the evaluation of patients following blunt injury with or without pelvic fractures.

The intravascular oxygenator (IVOX): preliminary results of a new means of performing extrapulmonary gas exchange. THE JOURNAL OF TRAUMA 1993; 35:399-404.

Abstract
Conventional management of adult respiratory distress syndrome (ARDS) with high minute ventilation, positive end-expiratory pressure (PEEP), and increased fractional inspired oxygen (FIO2) concentrations may worsen pulmonary injury. The intravascular oxygenator (IVOX) is a device made up of several hundred gas permeable hollow fibers that are inserted into the vena cava by femoral venous cutdown. Flow of gas through each fiber adds O2 and removes CO2 from the bloodstream. The purpose of this study was to determine if the IVOX significantly reduces the level of mechanical ventilatory support in ARDS patients. The IVOX was inserted in nine patients, and aborted in one because of technical complications. The IVOX increased PaO2 and reduced PaCO2, but the quantity of gas transfer was not sufficient to allow a reduction in PEEP, FIO2, or minute ventilation. Insertion of the IVOX decreased cardiac index and systemic oxygen delivery despite maximum fluid and inotropic support. Mortality was 80%. Although some gas exchange occurs, the current device does not allow a significant reduction in the level of mechanical ventilatory support and adversely affects systemic oxygen transport.
