Abstract
OBJECTIVE The goal was to characterize short-term kidney status and describe variation in early care utilization in a multicenter cohort of patients with childhood-onset systemic lupus erythematosus (cSLE) and nephritis. METHODS We analyzed previously collected prospective data from North American patients with cSLE with kidney biopsy-proven nephritis enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry from March 2017 through December 2019. We determined the proportion of patients with abnormal kidney status at the most recent registry visit and applied generalized linear mixed models to identify associated factors. We also calculated frequency of medication use, both during induction and ever recorded. RESULTS We identified 222 patients with kidney biopsy-proven nephritis, with 64% class III/IV nephritis on initial biopsy. At the most recent registry visit at median (interquartile range) of 17 (8-29) months from initial kidney biopsy, 58 of 106 patients (55%) with available data had abnormal kidney status. This finding was associated with male sex (odds ratio [OR] 3.88, 95% confidence interval [95% CI] 1.21-12.46) and age at cSLE diagnosis (OR 1.23, 95% CI 1.01-1.49). Patients with class IV nephritis were more likely than class III to receive cyclophosphamide and rituximab during induction. There was substantial variation in mycophenolate, cyclophosphamide, and rituximab ever use patterns across rheumatology centers. CONCLUSION In this cohort with predominately class III/IV nephritis, male sex and older age at cSLE diagnosis were associated with abnormal short-term kidney status. We also observed substantial variation in contemporary medication use for pediatric lupus nephritis between pediatric rheumatology centers. Additional studies are needed to better understand the impact of this variation on long-term kidney outcomes.

Intraarticular steroids as DMARD-sparing agents for juvenile idiopathic arthritis flares: Analysis of the Childhood Arthritis and Rheumatology Research Alliance Registry.

Abstract
BACKGROUND Children with juvenile idiopathic arthritis (JIA) who achieve a drug free remission often experience a flare of their disease requiring either intraarticular steroids (IAS) or systemic treatment with disease modifying anti-rheumatic drugs (DMARDs). IAS offer an opportunity to recapture disease control and avoid exposure to side effects from systemic immunosuppression. We examined a cohort of patients treated with IAS after drug free remission and report the probability of restarting systemic treatment within 12 months. METHODS We analyzed a cohort of patients from the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry who received IAS for a flare after a period of drug free remission. Historical factors and clinical characteristics and of the patients including data obtained at the time of treatment were analyzed. RESULTS We identified 46 patients who met the inclusion criteria. Of those with follow up data available 49% had restarted systemic treatment 6 months after IAS injection and 70% had restarted systemic treatment at 12 months. The proportion of patients with prior use of a biologic DMARD was the only factor that differed between patients who restarted systemic treatment those who did not, both at 6 months (79% vs 35%, p < 0.01) and 12 months (81% vs 33%, p < 0.05). CONCLUSION While IAS are an option for all patients who flare after drug free remission, it may not prevent the need to restart systemic treatment. Prior use of a biologic DMARD may predict lack of success for IAS. Those who previously received methotrexate only, on the other hand, are excellent candidates for IAS.

Abstract
BACKGROUND Social determinants of health (SDH) greatly influence outcomes during the first year of treatment in rheumatoid arthritis, a disease similar to polyarticular juvenile idiopathic arthritis (pJIA). We investigated the correlation of community poverty level and other SDH with the persistence of moderate to severe disease activity and functional disability over the first year of treatment in pJIA patients enrolled in the Childhood Arthritis and Rheumatology Research Alliance Registry. METHODS In this cohort study, unadjusted and adjusted generalized linear mixed effects models analyzed the effect of community poverty and other SDH on disease activity, using the clinical Juvenile Arthritis Disease Activity Score-10, and disability, using the Child Health Assessment Questionnaire, measured at baseline, 6, and 12 months. RESULTS One thousand six hundred eighty-four patients were identified. High community poverty (≥20% living below the federal poverty level) was associated with increased odds of functional disability (OR 1.82, 95% CI 1.28-2.60) but was not statistically significant after adjustment (aOR 1.23, 95% CI 0.81-1.86) and was not associated with increased disease activity. Non-white race/ethnicity was associated with higher disease activity (aOR 2.48, 95% CI: 1.41-4.36). Lower self-reported household income was associated with higher disease activity and persistent functional disability. Public insurance (aOR 1.56, 95% CI 1.06-2.29) and low family education (aOR 1.89, 95% CI 1.14-3.12) was associated with persistent functional disability. CONCLUSION High community poverty level was associated with persistent functional disability in unadjusted analysis but not with persistent moderate to high disease activity. Race/ethnicity and other SDH were associated with persistent disease activity and functional disability.

Abstract
Introduction Fetal Alcohol Spectrum Disorder (FASD) is a neurodevelopmental disorder caused by prenatal alcohol exposure (PAE). FASD research is a rapidly growing field that crosses multiple disciplines. To ensure research is relevant and meaningful for people living with FASD, their families, and the broader public there is a need to engage community members in setting priorities for research. Objectives Our primary objective was to formally identify the views of people living with FASD, their parents/caregivers, service providers, and the general community on the research priorities for FASD and alcohol use in pregnancy in Australia. Our secondary objective was to provide an overview of current research in the highest priority areas identified. Methods The approach for this study involved two community surveys and a consensus workshop, followed by a rapid literature review. Survey responses (n = 146) were collected and grouped using qualitative thematic analysis. The themes identified were then ranked in a second survey (n = 45). The 22 highest ranked themes were considered in a workshop with 21 community members, and consensus on the top ten priority areas was sought. The priority areas were grouped into conceptually similar topics and rapid literature reviews were undertaken on each. Results A diverse range of priorities was identified within key areas of prevention, diagnosis, and therapy. On request from participants, separate priority lists were developed by Aboriginal and non-Aboriginal participants. Conclusion There is need for a national network of researchers to take forward the research commenced by the Centre of Research Excellence, FASD Research Australia, in addressing community priorities. Key Words Community, priorities, FASD, rapid review, Australia.

Abstract
Recreational drug use (RDU) has been reported to be disproportionately higher in men who have sex with men (MSM) when compared to their heterosexual counterparts. To identify RDU, links to risky sexual practices and infections for MSM attending three sexual health clinics across Manchester, United Kingdom, a retrospective case note review was conducted using a random powered sample of service users attending three sites during 2014. Three hundred and fifty-seven case notes were reviewed across three sites. Eighteen per cent of service users reported any type of RDU. Use of at least one of the three drugs associated with chemsex (crystal methamphetamine, mephedrone, gamma hydroxybutyrate/gamma butyrolactone) was reported by 3.6%. A statistically significant difference was identified between non-drug users and any-drug users reporting: group sex (odds ratio [OR] 5.88, p = 0.013), condomless receptive anal intercourse (CRAI) (OR 2.77, p = 0.003) and condomless oral intercourse (OR 2.52, p = 0.016). A statistically significant difference was identified between chemsex-related drug user and non-drug user groups reporting: group sex (OR 13.05, p = 0.023), CRAI (OR 3.69, p = 0.029) and condomless insertive anal intercourse (OR 1.27, p = 0.039). There was also a statistically higher incidence of gonorrhoea infection in chemsex-related drug use compared with those not using drugs (p = 0.002, OR 6.88). This study identifies that substance use is common in MSM attending sexual health clinics in Manchester. High-risk sexual practices and certain sexually transmitted infections are more common in MSM reporting RDU.

Abstract
BACKGROUND Reverse camber shoes are a popular choice for immobilization following scarf osteotomy. There are no reports in the literature giving guidance on the duration of shoe use. METHODS Seventy-eight patients were reviewed. All had been advised to remain in reverse camber shoes until point of radiographic follow up. Data regarding time spent in shoes, associated adverse symptoms of shoes, and complications were recorded. RESULTS Three groups emerged. Group 1 (65 patients) wore the shoes for the instructed period of time. Group 2 (six patients) were those who removed the shoes early. Group 3 (seven patients) were those who wore the shoes following review. There were no differences in complication rates between the groups. CONCLUSION The use of post-op shoes is for symptom control. Our practice now is to advise patients to wear their shoes for as long as they feel necessary rather than giving them a prescriptive time limit.

Abstract
This is a case of an 11(1/2)-year-old diagnosed with Kawasaki disease at 6 months of age. Distal left main coronary aneurysm involving the proximal anterior descending and circumflex had progressed into a chronic total occlusion. We report the first application of a novel percutaneous technique using the CROSSER catheter system in a child. The CROSSER is a high-frequency mechanical vibration catheter-based technology developed to safely penetrate through calcific and noncalcific coronary artery occlusions. This is also the first Kawasaki disease patient to benefit from this technology; in this disease, coronary artery stenosis is typically associated with heavy calcification.

Abstract
BACKGROUND The StarClose Vascular Closure System is a femoral access site closure technology that uses a flexible nitinol clip to complete a circumferential, extravascular arteriotomy close. The Clip CLosure In Percutaneous Procedures study was initiated to study the safety and efficacy of the StarClose device in subjects undergoing diagnostic and interventional catheterization procedures. METHODS A total of 17 U.S. sites enrolled 596 subjects, with 483 subjects randomized at a 2:1 ratio to receive StarClose or standard compression of the arteriotomy after the percutaneous procedure. The study included roll-in (n = 113), diagnostic (n = 208), and interventional (n = 275) arms with a primary safety endpoint of major vascular complications through 30 days and a primary efficacy endpoint of postprocedure time to hemostasis. RESULTS The results of the diagnostic StarClose cohort have been reported separately. Results for the interventional arm revealed major vascular complications occurring in 1.1% of StarClose subjects (2/184) and 1.1% in manual compression subjects (1/91; P = 1.00). No infections were seen in either cohort. Minor complications in the StarClose interventional group occurred at a rate of 4.3% (8/184) and with compression at 9.9% (9/91; P = 0.107). Pseudoaneurysm or arteriovenous fistula was not seen with StarClose. With StarClose, procedural success was 100% (136/136) for the diagnostic group and 98.9% (181/183) in the interventional group. Device success for the treatment group was 86.8%. In the interventional cohort, 87.3% (158/181) of StarClose subjects reported a pain scale of 0-3 compared with 93.3% (84/90) in the compression group, which was not statistically different. CONCLUSIONS The clinical results of this study demonstrate that the StarClose Vascular Closure System is noninferior to manual compression with respect to the primary safety endpoint of major vascular events in subjects who undergo percutaneous interventional procedures. StarClose significantly reduced time to hemostasis, ambulation, and dischargeability when compared with compression.

Abstract
BACKGROUND The StarClose Vascular Closure System (Abbott Vascular, Redwood City, CA) features a nitinol clip that is designed to achieve closure of the femoral arteriotomy access site. The CLIP Study was performed to assess the safety and efficacy of StarClose when compared with standard manual compression following 5-6 French diagnostic or interventional percutaneous procedures. A substudy of this trial was designed to assess the utility of duplex ultrasonography to assess patency of the femoral artery and to determine access site complications (pseudoaneurysm, arteriovenous fistula, hematoma, deep vein thrombosis) in a multicenter prospective trial. This is the report of the duplex ultrasound (DUS) substudy of the CLIP trial. METHODS A total of 17 U.S. sites enrolled 596 subjects with 483 subjects randomized at a 2:1 ratio to receive StarClose or manual compression of the arteriotomy after a percutaneous procedure. The study included roll-in (n = 113), diagnostic (n = 208), and interventional (n = 275) arms with a primary safety endpoint of major vascular complications through 30 days and a primary efficacy endpoint of postprocedure time to hemostasis. A substudy of the CLIP interventional arm evaluated DUS images of the closure site at five study sites, targeting 100 subjects at day 30 following hemostasis. The DUS protocol was devised and implemented by an independent vascular ultrasound core laboratory with extensive experience in vascular device trials. DUS inguinal region from 6 cm proximal to 6 cm distal to the arteriotomy puncture was performed. A qualitative examination was performed to determine the presence of iatrogenic vascular injuries: hematoma, pseudoaneurysm (PSA), arteriovenous fistula (AVF), and arterial/venous thrombosis or stenosis using 2-dimensional gray scale, color, and focused Doppler images. RESULTS DUS of 96 subjects randomized to StarClose (n = 71) and compression (n = 25) were performed and evaluated. There was no evidence of hematoma, PSA, or AVF observed in the StarClose group. No StarClose subjects in the substudy had a PSA or AVF. All patients in the substudy demonstrated patency of the access site artery and vein without thrombosis or stenosis. Finally, in the entire study cohort, no clinically-driven DUS studies demonstrated iatrogenic vascular injury or vessel thrombosis in the StarClose treated patients. CONCLUSION DUS, a safe and reliable method for determining the safety and efficacy of access site closure devices, is a reliable, safe, inexpensive and accurate method of assessing vascular access site complications in multicenter trials. In this substudy of the CLIP study, DUS found no statistical difference in access site complications between the StarClose and manual compression groups. Both groups maintained vessel patency without stenosis, thrombosis, hematoma, pseudoaneurysm, or AV fistula.

Abstract
Behind Armour Blunt Trauma (BABT) is the non-penetrating injury resulting from the rapid deformation of armours covering the body. The deformation of the surface of an armour in contact with the body wall arises from the impact of a bullet or other projectile on its front face. The deformation is part of the retardation and energy absorbing process that captures the projectile. In extreme circumstances, the BABT may result in death, even though the projectile has not perforated the armour. An escalation of the available energy of bullets and the desire of armour designers to minimise the weight and bulk of personal armour systems will increase the risk of BABT in military and security forces personnel. In order to develop materials that can be interposed between the armour and the body wall to attenuate the transfer of energy into the body, it is essential that the mechanism of BABT is known. There is a great deal of activity within UK and NATO to unravel the interactions; the mechanism is likely to be a combination of stress (pressure) waves generated by the rapid initial motion of the rear of the armour, and shear deformation to viscera produced by gross deflection of the body wall. Physical and computer model systems are under development to characterise the biophysical processes and provide performance targets for materials to be placed between armours and the body wall in order to attenuate the injuries (trauma attenuating backings-TABs). The patho-physiological consequences of BABT are being clarified by research, but the injuries will have some of the features of blunt chest trauma observed in road traffic accidents and other forms of civilian blunt impact injury. The injuries also have characteristics of primary blast injury. An overview diagnosis and treatment is described.

Abstract
Revascularization options for intermediate sized vessels (2.5-2.9 mm) have historically been limited. IVAT is a pilot study to assess the efficacy and safety of debulking intermediate sized vessels using directional coronary atherectomy (DCA). Between March 1996 and June 1997, 50 patients were enrolled at seven hospitals in the United States. Of those patients, 70% presented with unstable angina and 52% had single vessel disease. Of the lesions treated, 96% were de novo. Adjunctive PTCA after DCA was performed in 90% of cases at the discretion of the investigator to maximize luminal diameter. The GTO DCA device was used in 90% of cases. Procedural success (residual stenosis <50% without major complications) was 94%. Stents were placed in 12% of patients. The only complications were three non-Q wave MIs. Mean reference vessel diameter increased from 2.49 mm pre-procedure to 2.57 mm after DCA and 2.61 post-procedure; mean MLD increased from 0.76 mm to 2.03 mm to 2.31 mm; and mean stenosis decreased from 70% to 21% post DCA and to 11% post procedure. At six months follow-up, 18.0% of target lesions required revascularization. Total revascularization, including non-target vessels, was 32%. These results suggest that DCA has a high procedural success rate and a low target lesion revascularization rate in intermediate sized vessels.

Abstract
OBJECTIVES The purpose of this study was to determine the incidence of bleeding, vascular, and ischemic complications using three different heparin regimens after successful intervention. BACKGROUND The ideal dose and duration of heparin infusion after successful coronary intervention is unknown. METHODS Patients were randomized to one of three heparin strategies after coronary intervention: Group 1 (n = 157 patients) received prolonged (12 to 24 h) heparin infusion followed by sheath removal; Group 2 (n = 120 patients) underwent early removal of sheaths, followed by reinstitution of heparin infusion for 12 to 18 h; Group 3 (n = 137 patients) did not receive any further heparin after intervention with early sheath removal. The primary end point of the study was the combined incidence of in-hospital bleeding and vascular events. Secondary end points included in-hospital ischemic events, length of stay, cost and one-month outcome. RESULTS After successful coronary intervention, 414 patients were randomized. Unstable angina or postinfarction angina was present in 83% of patients before intervention. The combined incidence of bleeding and vascular events was 21% in Group 1, 14% in Group 2 and 8% in Group 3 (p = 0.01). The overall incidence of in-hospital ischemic complications was 2.2%; there were no differences between groups. Length of hospital stay was shorter (p = 0.033) and adjusted hospital cost was lower (p < 0.001) for Group 3. At 30 days, the incidence of delayed cardiac and vascular events was similar for all three groups. CONCLUSIONS Heparin infusion after successful coronary intervention is associated with more minor bleeding and vascular injury, prolonged length of stay and increased cost. In-hospital and one-month ischemic events rarely occur after successful intervention, irrespective of heparin use. Routine postprocedure heparin is not recommended, even in patients who present with unstable ischemic syndromes.

Abstract
A total of 670 adults living or working with leprosy patients, were examined for a BCG vaccination scar, and skin-tested with four new tuberculins. Based on the results 513 were vaccinated, 65 with Bacille de Calmette et Guérin (BCG) alone, 66 with BCG plus killed Mycobacterium vaccae and 382 with killed M. vaccae alone. Skin-testing was repeated 2-3 years later on 344 subjects, when all three vaccines were found to have been highly successful in increasing responses to Tuberculin and Leprosin A (p < 0.0005) with increased immune recognition of common and species-specific antigens. Mean diameters of induration to each skin-test were greatest in recipients of BCG alone (p < 0.05), which suggests that better immuno-regulation occurs after receiving vaccines that incorporate M. vaccae. The results suggest 10(8) M. vaccae alone might prove a valuable future vaccine, which would not require selective pre-vaccination procedures.

Abstract
Light microscopic, histochemical, immunohistochemical, and ultrastructural methods were used to examine myocardial epithelial masses in the hearts of ten cattle. The tissues consisted of paraffin-embedded or formalin-fixed samples from eight hearts that were being inspected in slaughter houses and from two hearts from calves that died of septicemia. The ages of the cattle ranged from 4 days to 12 years; the breeds were unspecified for all but one Hereford female and the two Holstein calves; and there were three males, four females, and three steers. The masses in these cases were compared with similar appearing lesions found in other animal species. The lesions in the bovine hearts were single to multiple, well circumscribed, found in the left ventricle wall, and composed of squamous to cuboidal epithelial cells that formed tubular, ductular, and acinar structures with lumens that were void or filled with amorphous protein globules. Electron microscopic examination revealed epithelial cells that had sparse apical microvilli, tight apical intercellular junctions, perinuclear bundles of filaments, and rare cilia. Almost half of the bovine epithelial masses (4/9) had occasional diastase-resistant periodic acid-Schiff-positive granules in their cytoplasm, and few had hyaluronidase-resistant alcian blue-positive granules (2/9) or colloidal iron-positive granules (1/9). All myocardial masses had abundant collagen surrounding the tubular and acinar structures, and 2/9 had elastin fibers as well. None of the myocardial masses had Churukian-Schenk or Fontana Masson's silver staining granules in epithelial cells. Immunohistochemically, all bovine myocardial tumors stained positively for cytokeratin (8/8), and occasional masses stained positively for vimentin (3/8) or carcinoembryonic antigen (3/8). None of the masses stained positively for desmin. The myocardial epithelial tumors most likely represent endodermal rests of tissue misplaced during organogenesis.

Abstract
Reports on a survey of 1990 and 1991 graduates entering the speech and language therapy profession in the UK and on the experiences of six new therapists in one "good practice" area, Ayrshire and Arran Health Board. Results show that new therapists were given a great deal of help and support from professional managers, and valued it highly. They chose posts which offered a mixed client load and good induction packages. Pre-service training reflected work carried out in service, but all client groups had not been accessed during training. Issues relating to throughput and case-load management required most support. They made successful personal adaptations to the work environment, and managers found them effective overall. Calculates the costs of supporting new therapists. Highlights the need to maintain professional support and discusses the potential difficulties involved in doing so in relation to NHS reforms.

Abstract
This article has examined the role of the nurse in clinical trials, particularly the clinical, administrative, and research roles. Components of each role and characteristics essential for the implementation of each role have been examined. The nursing role in clinical trials research is undergoing major transformation from the perception of the nurse as a data collector for medical research to the recognition of the nurse as an essential member of the research team with a multifaceted role. Miaskowski identifies two factors influencing the development of oncology nursing practice; scientific and technological advances and societal factors relating to the perception of cancer as a disease and changes in the nursing profession. Certainly it is recognized that progress in basic science research will lead to an increase in the complexity and number of clinical trials. Nurses have clearly implemented the roles necessary to be vital participants and have contributed to answering questions leading to improved treatments for the patients with cancer.

Abstract
Seroconversion for HIV antibody occurred in two homosexual men who reported no anal intercourse for greater than or equal to 5 years and multiple episodes of receptive oral intercourse with ejaculation. Neither man reported intravenous drug use or receipt of blood products. The last antibody-negative specimen was also negative by the polymerase chain reaction and p24 antigen assays. All sexually active persons should be clearly counselled that receptive oral intercourse with ejaculation carries a potential risk of HIV transmission.

Abstract
OBJECTIVE--To characterise the natural history of sexually transmitted HIV-I infection in homosexual and bisexual men. DESIGN--Cohort study. SETTING--San Francisco municipal sexually transmitted disease clinic. PATIENTS--Cohort included 6705 homosexual and bisexual men originally recruited from 1978 to 1980 for studies of sexually transmitted hepatitis B. This analysis is of 489 cohort members who were either HIV-I seropositive on entry into the cohort (n = 312) or seroconverted during the study period and had less than or equal to 24 months between the dates of their last seronegative and first seropositive specimens (n = 177). A subset of 442 of these men was examined in 1988 or 1989 or had been reported to have developed AIDS. MAIN OUTCOME MEASURES--Development of clinical signs and symptoms of HIV-I infection, including AIDS, AIDS related complex, asymptomatic generalised lymphadenopathy, and no signs or symptoms of infection. MEASUREMENTS AND MAIN RESULTS--Of the 422 men examined in 1988 or 1989 or reported as having AIDS, 341 had been infected from 1977 to 1980; 49% (167) of these men had died of AIDS, 10% (34) were alive with AIDS, 19% (65) had AIDS related complex, 3% (10) had asymptomatic generalised lymphadenopathy, and 19% (34) had no clinical signs or symptoms of HIV-I infection. Cumulative risk of AIDS by duration of HIV-I infection was analysed for all 489 men by the Kaplan-Meier method. Of these 489 men, 226 (46%) had been diagnosed as having AIDS. We estimated that 13% of cohort members will have developed AIDS within five years of seroconversion, 51% within 10 years, and 54% within 11.1 years. CONCLUSION--Our analysis confirming the importance of duration of infection to clinical state and the high risk of AIDS after infection underscores the importance of continuing efforts both to prevent transmission of HIV-I and to develop further treatments to slow or stall the progression of HIV-I infection to AIDS.

Abstract
Carcasses from 18 Holstein cows from Nevada, California, and Oregon were condemned because of grossly visible sarcocysts of Sarcocystis hirsuta. Sarcocysts were white to dull white, 2 to 7 mm long, and approximately 1 mm wide. Sarcocysts were most numerous in muscles of diaphragm, flank, and limbs and were able to infect laboratory-raised cats.

Abstract
To determine whether neurological and neuropsychological abnormalities are associated with clinical manifestations of human immunodeficiency virus type 1 (HIV-1) infection in men who do not have acquired immunodeficiency syndrome (AIDS), we performed a historical prospective and cross-sectional study. One hundred HIV-1 seropositive homosexual or bisexual men, of whom 26 had AIDS-related complex, 31 had generalized lymphadenopathy, and 43 had no signs or symptoms of HIV-1 infection, and 157 HIV-1 seronegative men were enrolled from a cohort of 6,701 men who were originally recruited between 1978 and 1980 for studies of hepatitis B virus infection. Evaluation included medical history, physical examination, and neuropsychological tests. Of 26 HIV-1 seropositive subjects with AIDS-related complex, 11 (42%) reported neurological, cognitive, or affective symptoms compared with 30 (19%) of 157 HIV-1 seronegative subjects (relative risk = 2.2, p = 0.02). On neuropsychological testing, subjects with AIDS-related complex performed at a significantly lower level than the HIV-1 seronegative group (p = 0.001). A significantly higher percentage of subjects with AIDS-related complex (8[31%]of 26) than HIV-1 seronegative subjects (19 [12%] of 157) had abnormal results on two or more neuropsychological tests (rate ratio = 2.5, p = 0.03). Symptoms and impairment on neuropsychological tests were correlated only within the group who had AIDS-related complex. Subjects with generalized lymphadenopathy and subjects who had no signs or symptoms of HIV-1 infection were not different from HIV-1 seronegative subjects with respect to symptoms or performance on neuropsychological tests.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
WR-2721 is an aminothiol compound; in the animal model it protects against the nephrotoxicity, neurotoxicity, and hematologic toxicity of cis-platinum. We initiated Phase I trials of WR-2721 and cis-platinum to determine toxicity when WR-2721 was given prior to escalating doses of cis-platinum. With mannitol diuresis and WR-2721, transient nephrotoxicity occurred in 9 of 30 (27%) patients treated with cis-platinum 150 mg/m2 and 7% of patients given with cis-platinum 120 mg/m2. Bone marrow suppression was mild and infrequent. Mild to moderate peripheral neuropathies occurred in 26% of patients courses following a mean cumulative cis-platinum dose of 725 mg/m2. Objective partial responses were observed in 53 of 118 (45%) patients with measurable disease. Antitumor responses were observed in 25 of 53 patients with metastatic melanoma, 12 of 22 patients with locally recurrent or metastatic head and neck cancer, and 7 of 13 patients with metastatic breast cancer refractory to conventional chemotherapy. Controlled studies of WR-2721 and cis-platinum will be performed in the Eastern Cooperative Oncology Group in these disease sites to better define the activity of this regimen and its toxicity.

Abstract
Continuous measurement of arterial oxygen saturation (SaO2) using pulse oximetry has become a common monitoring and management technique in critically ill hospitalized patients. To determine the impact of SaO2 monitoring on emergency patient management, we conducted a prospective uncontrolled clinical trial on 40 adult patients presenting to the emergency department with acute respiratory illness, such as emphysema, asthma, or pulmonary edema. Recorded data included hemograms, arterial blood gases, subsequent therapy, and response to treatment. Additionally, the "early warning" capability of SaO2 monitoring was analyzed by recording the severity and outcome of hypoxemic events during treatment. Mean duration of usage for the 40 oximeters in the ED was 1.8 hours; all probes functioned reliably over a wide range of systolic pressures (80 to 206 mm Hg), heart rates (40 to 180 beats per minute), and hematocrits (20% to 58%). There was good correlation between simultaneous pulse oximeter values and both directly measured SaO2 (r = 0.95) and saturations derived from measured arterial PaO2 (r = 0.94). The device detected several otherwise unrecognized drops in arterial saturation that were confirmed by laboratory analysis. Other clinical situations in which the pulse oximeter was found useful in the ED are reviewed. We conclude that continuous measurement of SaO2 can improve the monitoring of ED patients, increase the precision of therapy, detect hypoxemia during intubation, suctioning, and other treatments, and detect clinically unsuspected changes in arterial oxygenation.

Abstract
Five X-chromosome DNA markers were typed on 261 members of three large kindreds with Alport syndrome (hereditary glomerulonephritis). Lod scores greater than 3.0 for linkage between the disease locus and two of the markers confirmed X-linked inheritance of the disease. A decreasing gradient in the estimated recombination fractions observed when the markers were ordered on the basis of their map locations suggested that the disease locus is on the long arm distal to all the markers typed in this study. Using three-locus analysis we rejected all but three map orders for the six loci (the disease locus and five markers). In all three the Alport syndrome locus was on the long arm of the X chromosome distal to all the markers. Two types of Alport syndrome were represented in the three kindreds. Affected males in one kindred developed deafness in addition to nephritis; deafness did not occur in members of the other two kindreds. Although larger recombination-fraction estimates were obtained for all five markers in the kindreds without deafness, the difference was significant for only one marker. Evidence of heterogeneity was not found in tests using two markers. Markers distal to the disease locus are needed to determine whether two loci are responsible for the two types of Alport syndrome.

Abstract
Our initial attempt to map NF was directed towards chromosomes 4 and 19, both of which had provided positive evidence for linkage in previous reports. This analysis showed no evidence in support of either hypothesis. Our second attempt at mapping NF was a general search of the genome, analysing a set of markers selected according to their degree of polymorphism, chromosomal location, ease of use, and availability. Data for linkage analysis were obtained from 17 multiplex families which are segregating a gene for NF. Linkage analyses were performed using PAP. Of note is the lod score of +1.17 at a recombination fraction of 0.1 between NF and the centromere of chromosome 17.

Abstract
In two patients, persistent hiccups were an unusual presenting manifestation of hyponatremia. Persistent hiccups occur in a variety of serious diseases, including metabolic and electrolyte disorders. They may cause the victim significant distress and may be refractory to most treatments. Hiccups lasting more than 24 hours require investigation for an underlying organic etiology, with hyponatremia included in the differential diagnosis.

Abstract
Activated charcoal has found a renewed role in the management of overdosed patients. Routinely administered to reduce the gastrointestinal (GI) absorption of many drugs, growing evidence indicates that repeated doses of charcoal also may enhance drug elimination. Some drugs are excreted into the bile or gastric fluids (phencyclidine, digoxin) and are reabsorbed. Other drugs (theophylline, phenobarbital) can diffuse from the plasma into the lumen of the GI tract. Activated charcoal is administered at regular intervals to sequester these toxins in the GI tract, eventually causing their excretion in feces. This article reviews the evidence for the safety and efficacy of repetitive charcoal therapy. While supportive management remains the mainstay of therapy in poisoned patients, activated charcoal is inexpensive, effective, simple to administer, and may obviate the need for more invasive methods of toxin removal.

Abstract
Linkage analysis of 15 Utah kindreds demonstrated that a gene responsible for von Recklinghausen neurofibromatosis (NF) is located near the centromere on chromosome 17. The families also gave no evidence for heterogeneity, indicating that a significant proportion of NF cases are due to mutations at a single locus. Further genetic analysis can now refine this localization and may lead to the eventual identification and cloning of the defective gene responsible for this disorder.

Abstract
Research in emergency medicine is a necessary component for the growth and development of the academic discipline. Although the need exists for competent physician investigators, most graduates of emergency medicine residencies have had little structured education in research design or methodology. This is particularly true in community hospital programs with little funding allocated to research, limited facilities, and few staff members actively involved in research. Our purpose is to describe a research curriculum designed to operate within a community-based residency program. This curriculum identifies a detailed set of educational objectives in research techniques with the expectation that on completion of the residency program, the resident will be able to critically evaluate medical literature and independently design a research project. We have developed a specific plan for meeting these objectives with coordinated seminars, readings, journal clubs, research projects or exhibits, and professional conferences. We suggest some practical methods of motivating residents and attending staff to pursue clinical investigation.

Abstract
Odorization of inert gas can serve to warn workers in an enclosed space about gas leaking into the space. This psychophysical investigation, performed under conditions of directed attention, examined two candidates for possible odorization of argon:pyridine and cis-3-hexen-1-ol. Detection thresholds for pyridine and cis-3-hexen-1-ol in argon were 106 ppb and 19 ppb, respectively. Practice over four days yielded modest improvement in the detection of both odorants. For cis-3-hexen-1-ol, smokers had marginally lower thresholds than nonsmokers and older participants had slightly higher thresholds than younger participants. Gender, smoking status and age had no reliable influence on threshold for pyridine. This outcome indicated desirable perceptual stability for pyridine. Additional experiments dealt with the perceived intensity of pyridine and cis-3-hexen-1-ol over time in the realistic setting of an environmental chamber. Visitors to the chamber and occupants in the chamber assessed perceived magnitude at 5-min intervals for up to 60 min during injections of odorized argon into the chamber. Participants could gauge and track the concentration of pyridine much better than that of cis-3-hexen-1-ol. This held true for occupants almost to the same degree as visitors, though occupants inevitably exhibited some olfactory adaptation. Hence, the suprathreshold measurements also gave strong relative endorsement to pyridine. Calculations based on the experimental results indicated that odorization of the inert gas stream with 3 to 10 ppm (v/v) pyridine should suffice to warn occupants or visitors of an argon buildup of any severity. Field studies should permit a definitive judgment of the best concentration to use in practice.

Abstract
The growing number of elderly in the United States will continue to increase the demand for emergency services. Although the emergency medicine core curriculum, as defined by the American College of Emergency Physicians, requires mandatory training in pediatrics, there is no mention of geriatric care. A special body of knowledge regarding normal aging as well as the special presentation of disease in the elderly is required to provide optimum care for the aged patient. We present an integrated geriatric curriculum designed to operate within a three-year emergency medicine residency program. This curriculum identifies specific educational objectives for training in geriatric emergencies that can be summarized as follows: identify those impairments and functional disorders that often complicate diagnosis and therapy; acquire an understanding of how physiologic changes in aging affect normal laboratory and radiologic values; develop knowledge of drug side effects and interactions in this population; understand and treat the group of disease peculiar to the elderly; recognize diseases and injuries that present a different clinical picture in old age; and differentiate and treat common psychosocial emergencies in the elderly. These educational objectives are further defined using a specific interlinked framework of didactic presentations, journal clubs, case conferences, therapeutic audits, formal rotations, and consultants. This format will provide valuable educational experiences for the emergency medicine resident and may strengthen positive attitudes toward geriatric medicine.

Abstract
Fiberoptic pulmonary artery catheters provide a practical method for continuously measuring the amount of oxygen in mixed venous blood. To characterize the usefulness of mixed venous oxygen saturation in managing patients with sepsis, we performed serial hemodynamic measurements on 20 patients with documented septic shock. There was a highly significant positive correlation between increases or decreases of 5% or more in mixed venous oxygen saturation and corresponding changes in oxygen delivery (r = 0.95) and oxygen consumption (r = 0.96). Mixed venous oxygen saturation less than 65% was clinically unacceptable in patients with sepsis and was associated with a poor prognosis. In this study, measurement of mixed venous oxygen saturation was a valuable predictor of survival in patients with septic shock and provided a means of continuously monitoring the status of tissue oxygenation.

Abstract
A 24-year-old man presented to the emergency department with acute anticholinergic symptoms, hallucinations, and bizarre behavior following a large ingestion of diphenhydramine (Benadryl). Because of the large number of nonprescription preparations containing this antihistamine, similar ingestions are becoming increasingly frequent. Minor anticholinergic side effects associated with diphenhydramine are general medical knowledge. The effects of overdosage are less well known. The clinical presentation of toxic psychosis, its differential diagnosis, and its subsequent treatment are discussed.
