Abstract
Rationale & Objective Understanding national attitudes about living kidney donation will enable us to identify and address existing disincentives to living kidney donation. We performed a national survey to describe living kidney donation perceptions, perceived factors that affect the willingness to donate, and analyzed differences by demographic subgroups. Study Design The survey items captured living kidney donation awareness, living kidney donation knowledge, willingness to donate, and barriers and facilitators to living kidney donation. Setting & Population We surveyed 802 US adults (aged 25-65 years) in June 2021, randomly selected from an online platform with diverse representation. Analytical Approach We developed summed, scaled indices to assess the association between the living kidney donation knowledge (9 items) and the willingness to donate (8 items) to self-reported demographic characteristics and other variables of interest using analysis of variance. All other associations for categorical questions were calculated using Pearson's χ2 and Fisher exact tests. We inductively evaluated free-text responses to identify additional barriers and facilitators to living kidney donation. Results Most (86.6%) of the respondents reported that they might or would definitely consider donating a kidney while they were still living. Barriers to living kidney donation included concerns about the risk of the surgery, paying for medical expenses, and potential health effects. Facilitators to living kidney donation included having information on the donation surgery's safety, knowing that the donor would not have to pay for medical expenses related to the donation, and hearing living kidney donation success stories. Awareness of the ability to participate in kidney-paired donation was associated with a higher willingness to donate. Limitations Potential for selection bias resulting from the use of survey panels and varied incentive amounts, and measurement error related to respondents' attention level. Conclusions Most people would consider becoming a living kidney donor. Increased rates of living kidney donation may be possible with investment in culturally competent educational interventions that address risks associated with donating, policies that reduce financial disincentives, and communication campaigns that raise awareness of kidney-paired donation and living kidney donation.

Abstract
To date, thousands of living donor kidneys have been shipped through kidney paired donation (KPD). To expand on this growing segment of living donor transplantation, we evaluated the effect of advanced age donation ("oldest kidneys") and prolonged cold ischemia time ("coldest kidneys") on graft function and survival using the National Kidney Registry database from February 2008 to May 2018. Donors were stratified by age at time of donation (<65 or ≥65 years) and kidneys were stratified by cold ischemia time (<16 or ≥16 hours). We evaluated delayed graft function and death-censored graft failure (DCGF) for up to seven posttransplant years. Of the 2363 shipped living donor kidney transplants, 4.1% of donors were ≥65 years and 6.0% of transplanted kidneys had cold ischemia times ≥16 hours. Delayed graft function and DCGF occurred in 5.2% and 4.7% of cases. There were no significant associations between delayed graft function and donor age (P = .947) or cold ischemia (P = .532). Donor age and cold ischemia time were not predictive of delayed graft function (OR = 0.86,1.20; P = .8, .6) or DCGF (HR = 1.38,0.35, P = .5, .1). These findings may alleviate concerns surrounding the utilization of kidneys from older donors or those originating from distant transplant centers.

Abstract
Concerns regarding the potential for broken chains and "reneges" within kidney paired donation (KPD) and its effect on chain length have been raised previously. Although these concerns have been tested in simulation studies, real-world data have yet to be evaluated. The purpose of this study was to evaluate the actual rate and causes of broken chains within a large KPD program. All patients undergoing renal transplantation through the National Kidney Registry from 2008 through May 2016 were included for analysis. Broken chains and loops were identified. A total of 344 chains and 78 loops were completed during the study period, yielding a total of 1748 transplants. Twenty broken chains and one broken loop were identified. The mean chain length (number of transplants) within broken chains was 4.8 compared with 4.6 of completed chains (p = 0.78). The most common causes of a broken chain were donor medical issues incurred while acting as a bridge donor (n = 8), donors electing not to proceed (n = 6), and kidneys being declined by the recipient surgeon (n = 4). All recipients involved in a broken chain subsequently received a transplant. Based on the results, broken chains are infrequent, are rarely due to lack of donor motivation, and have no significant impact on chain length.

Abstract
The continued growth of kidney paired donation (KPD) to facilitate transplantation for otherwise incompatible or suboptimal living kidney donors and recipients has depended on a balance between the logistics required for patients and the collaborating transplant centers. The formation of chains for KPD and the shipping of kidneys have permitted networks such as the National Kidney Registry (NKR) to offer KPD to patients over a transcontinental area. However, over the last 3 years, we have encountered patient requests for a more flexible experience in KPD to meet their individual needs often due to rigid time constraints. To accommodate these requests, we have developed an Advanced Donation Program (ADP) in which the donor desires to donate by a specific date, but their paired recipient has not yet been matched to a specific donor or scheduled for surgery. After obtaining careful informed consent from both the donor and paired recipient, 10 KPD chains were constructed using an ADP donor. These 10 ADP donors have facilitated 47 transplants, and thus far eight of their paired recipients have received a kidney within a mean of 178 (range 10-562) days. The ADP is a viable method to support time limited donors in a KPD network.

Abstract
Studies have shown that kidney donation to a spouse has a positive impact on marriage. This study was done to evaluate the impact on marriage when donation occurs to someone other than the spouse. Two groups of donors from our centre who donated around the same period were studied: donation to a spouse (spouse donor (SD)) or to someone other than the spouse (non-spouse donor (ND)). A survey, the Revised Dyadic Adjustment Scale, was used to evaluate the effect of donation on the marriage. This tool consists of 14 questions that measure how satisfying and stable the relationship is. The results showed equal or better marriage scores in the ND group compared with the SD group. The NDs scored higher on two questions, one regarding agreement or disagreement on career choices (P = 0.05) and the other regarding the frequency of having stimulating exchanges of ideas with one's spouse (P = 0.02). With the highest possible total score of 69, NDs scored 53.4 and SDs scored 47.7 (P = 0.16). Scores of 47 and below indicate marital distress. In one final additional question, 97% of NDs reported 'no change or good effect' on the marriage, similar to 91% for SDs (P = 0.46). This is the first study to evaluate the effect of kidney donation on the state of marriage when the spouse is not the recipient. It appears that marriage is not impacted negatively when kidney donation occurs to someone other than the spouse.

Abstract
BACKGROUND Kidney paired donation chains are initiated by nondirected donors and propagated by donors within the chain of transplants, or chain donors. OBJECTIVE To compare psychosocial and functional outcomes, and to test coercion, of chain donors in paired exchange versus traditional directed donors who have an established relationship with the recipient. METHODS Thirty chain donors from a transplant center who were part of the National Kidney Registry paired exchange program were compared with 34 traditional donors who donated around the same time. Participants completed online surveys: the postdonation section of the Living Donor Expectancies Questionnaire was used to assess psychosocial and functional outcomes 1 to 6 years after donation. A survey to assess coercion was used as well. RESULTS Chain donors and traditional donors were similar in terms of sex, race, age, and time after donation. The 2 groups had similar altruistic motives in donating their kidney, and both types of donors mentioned psychological benefits. No differences were found on questions regarding psychosocial outcomes save for the "quid pro quo scale" (P= .01), which suggested that the traditional donors felt more that the recipients are indebted to them. The 2 groups did not differ significantly in the coercion measure. Pressure to donate and stress of donation were not greater in chain donors than traditional donors (P= .60). CONCLUSION Kidney donors in kidney paired donation chains do as well as traditional donors psychosocially without any increased tendency toward experiencing coercion.

Abstract
Multi-center kidney paired donation (KPD) is an exciting new transplant option that has not yet approached its full potential. One barrier to progress is accurate virtual crossmatching for KPD waitlists with many highly sensitized patients. Virtual crossmatch results from a large multi-center consortium, the National Kidney Registry (NKR), were analyzed to determine the effectiveness of flexible center-specific criteria for virtual crossmatching. Approximately two-thirds of the patients on the NKR waitlist are highly sensitized (>80% CPRA). These patients have antibodies against HLA-A (63%), HLA-B (66%), HLA-C (41%), HLA-DRB1 (60%), HLA-DRB3/4/5 (18-22%), HLA-DQB1 (54%) and HLA-DPB1 (26%). With donors typed for these loci before activation, 91% of virtual crossmatches accurately predicted an acceptable cell-based donor crossmatch. Failed virtual crossmatches were attributed to equivocal virtual crossmatches (46%), changes in HLA antibodies (21%), antibodies against HLA-DQA (6%), transcription errors (6%), suspected non-HLA antibodies (5%), allele-specific antibodies (1%) and unknown causes (15%). Some failed crossmatches could be prevented by modifiable factors such as more frequent assessment of HLA antibodies, DQA1 typing of donors and auditing data entry. Importantly, when transplant centers have flexibility to define crossmatch criteria, it is currently feasible to use virtual crossmatching for highly sensitized patients to reliably predict acceptable cell-based crossmatches.

Abstract
Virtual reality simulation software (VRS - FocalSim Version 4.40 with VRS prototype, Computerized Medical Systems, St. Louis, MO) is a new radiation dose planning tool that allows for 3D visualization of the patient and the machine couch (treatment table) in relationship to the linear accelerator. This allows the radiation treatment planner to have a "room's-eye-view" and enhances the process of virtual simulation. The aim of this study was to compare VRS to a standard planning program (XiO - Version 4.50, Computerized Medical Systems, St. Louis, MO) in regards to the time it took to use each program, the angles chosen in each, and to determine if there was a dosimetric benefit to using VRS. Ten patients who had undergone left-sided lumpectomies were chosen to have treatment plans generated. A partial breast irradiation (PBI) treatment plan by external beam radiation therapy (EBRT) was generated for each patient using two different methods. In the first method the full plan was generated using XiO software. In the second method beam angles were chosen using the VRS software, those angles were transferred to XiO, and the remaining part of the plan was completed using XiO (since VRS does not allow dose calculations). On average, using VRS to choose angles took about 10 minutes longer than XiO. None of the five gantry angles differed significantly between the two programs, but four of the five couch angles did. Dose-volume histogram (DVH) data showed a significantly better conformality index, and trends toward decreased hot spots and increased coverage of the planed treatment volume (PTV) when using VRS. However, when angels were chosen in VRS a greater volume of the ipsilateral breast received a low dose of radiation (between 3% and 50% of the prescribed dose) (VRS = 23.06%, XiO = 19.57%, p < 0.0005). A significant advantage that VRS provided over XiO was the ability to detect potential collisions prior to actual treatment of the patient in three of the ten patients studied. The potential to save time with VRS by not having to redo plans because of a collision increases clinic efficiency.

Abstract
OBJECTIVE The aim of this study was to analyze clinical characteristics of rocuronium as premedication for nonemergent intubation in infants. STUDY DESIGN Preterm infants requiring nonemergent intubation were randomized to receive atropine and fentanyl with or without rocuronium. Outcomes, patient characteristics and intubator's experience were noted. Onset, duration and degree of clinical paralysis were recorded for rocuronium group and for older infants receiving rocuronium per unit protocol. RESULT Forty-four intubations were randomized (20 rocuronium, 24 control). Groups were similar in chronological and corrected gestational age, weight and intubator's experience. Successful intubation on first attempt was achieved in 35% of intubations under rocuronium vs 8% of controls; rocuronium was the only significant variable by logistic regression (odds ratio=0.052, P=0.029). Complete paralysis was reported in 80% of 57 rocuronium intubations; onset ranged from 14 to 178 s (65.9±43.4), and duration from 1 to 60 min (16.3±13.5). CONCLUSION Rocuronium facilitated successful intubation and provided clinical paralysis quickly in most infants.

Abstract
Abstract
INTRODUCTION:
Ductal carcinoma in situ (DCIS) is a non-invasive breast cancer, which often grows discontinuously within the breast tissue. Younger age, residual mammographic microcalcifications, positive surgical margins, tumor size, nuclear grade and architectural type are consistently related to ipsilateral breast tumor recurrence in DCIS. To re-excise or not when a lumpectomy margin is close is a controversial issue for breast pathologists, surgeons and oncologists, and often no residual disease is found when a re-excision is performed. The aim of this study is to investigate the clinico-pathological features of DCIS that might predict residual disease in the re-excision specimen in patients treated by lumpectomy with either positive or close margins. METHODS:
Consecutive patients with DCIS who required postlumpectomy re-excision either for positive or for close margins were selected in this retrospective analysis. Close margin was defined as less than 0.1 cm. The initial lumpectomy specimens were examined for tumor size, architectural type, nuclear grade and margin status, and patient age was considered. The subsequent re-excision specimens were analyzed for residual disease. The clinico-pathological features of original lumpectomy specimens were correlated with the presence or absence of residual DCIS in the re-excision specimens. Logistic regression statistical test was used to determine if any of these clinico-pathological features predicted the presence or absence of DCIS in the subsequent re-excision specimens. RESULTS:
There were 37 cases of DCIS without accompanying invasive carcinoma that had positive or close resection margins (positive margin n=8; 21.6%, close margin n=29; 78.4%). Age of the patients ranged from 30 to 93 years. DCIS present in the original lumpectomy specimen was comedo type with necrosis n=8; 21.6% and non-comedo type n-29; 78.4%. Twenty-one lumpectomy specimens (57%) exhibited more than one type of DCIS. Four tumors were nuclear grade 1 (10.8%). 17 were nuclear grade 2 (45.9%), and 16 were nuclear grade 3 (43.2%). Residual DCIS was present in 20 out of 37 (54.1%) re-excision specimens. Six out of 8 (75%) comedo DCIS had residual disease, compared to 14 out of 29 (48.3%) non-comedo DCIS. Eleven out of 20 patients (55%) with residual disease were younger than 60 years. The correlation of patient age and type of DCIS to residual disease in the re-excision specimens was short of statistical significance due to small size of study sample (p value = 0.178 and 0.175 respectively). There was no statistically significant association between nuclear grade and distance to margin with residual disease in re-excision specimens (p value = 0.757 and 0.734 respectively). CONCLUSION:
Younger age and comedo type DCIS may be important factors in predicting residual disease in the re-excision specimens. If this can be confirmed in a larger, multi-institutional data set, there could be a more tailored selection of who needs a re-excision.

Abstract
Abstract
Background: Regional Nodal Irradiation (RNI) is indicated for breast cancer patients with ≥4 positive axillary lymph nodes (ALN). The need for RNI is unclear for women who don't undergo axillary lymph node dissection (ALND) yet have 1-3 positive sentinel lymph nodes (SLN). In an effort to guide clinician decision-making and potentially spare patients combined toxicities of ALND and radiation, the purpose of this study was to create a decision tree of clinicopathologic variable interactions to predict patients with ≥4 positive ALN.Methods: We reviewed the records of 197 women with breast tumors <5cm and 1-3 positive SLN. After ALND, patients were labeled as having < 4 or ≥ 4 positive ALN. Ten clinicopathologic predictive variables were identified for analysis: patient age, size of tumor, histological type, tumor grade, number of metastatic SLN, largest SLN metastasis size, detection method, estrogen receptor, Ki67 and lymphovascular invasion (LVI). The analysis used Chi-Square Automatic Interaction Detection (CHAID SPSS), a non-parametric, stepwise “regression tree” analysis, with Bonferroni adjusted p-values to create a decision tree.Results: 141 patients had < 4 and 56 had ≥ 4 positive ALN. Three variables were selected into the CHAID tree: LVI, the number of metastatic SLNs, and largest SLN metastasis size. 100% of patients (N=42) had < 4 positive ALN if negative for LVI and had only 1 positive SLN with a metastasis size < 0.2cm (p-value < 0.0432). For patients with LVI (N=77), 13 of 14 (93%) had < 4 positive ALN if the SLN metastasis size was < 0.2cm (p < .0014). The highest prevalence of ≥ 4 positive ALN were patients with LVI and a SLN metastasis size > 0.2cm.Conclusion: The CHAID analysis more accurately predicted patients with < 4 positive ALN compared to those with ≥4. The decision tree provides a new tool for the clinician to determine the necessity for RNI without ALND.

Abstract
e11540 Background: Regional nodal irradiation (RNI) is indicated for breast cancer patients with ≥ 4 positive axillary lymph nodes (ALN). The need for RNI is unclear for women with T1–2 tumors and 1–3 positive sentinel lymph nodes (SLN) who don’t undergo axillary lymph node dissection (ALND). In an effort to guide clinician decision-making and potentially spare patients combined toxicities of ALND and radiation, the purpose of this study was to create a decision tree of clinicopathologic variables to predict patients with ≥ 4 positive ALN. Methods: We reviewed the records of 197 women with T1–2 tumors and 1–3 positive SLN. All patients underwent a complete ALND to determine the number of positive ALN. The patients were divided into 2 groups: < 4 or ≥ 4 positive ALN. Ten clinicopathologic predictive variables were identified for analysis: patient age, size of tumor, histological type, tumor grade, number of metastatic SLN, largest SLN metastasis size, detection method, estrogen receptor, Ki67 and lymphovascular invasion (LVI). The analysis used Chi-Square Automatic Interaction Detection (CHAID SPSS), a non-parametric, stepwise “regression tree” analysis, with Bonferroni adjusted p-values to create a decision tree. Results: 141 (72%) patients had < 4 and 56 (28%) had ≥ 4 positive ALN. Three variables were selected into the CHAID tree based upon maximum predictability: LVI, the number of metastatic SLNs, and largest SLN metastasis size. 100% of patients (N=42) had < 4 positive ALN if negative for LVI and had only 1 positive SLN with a metastasis size < 0.2cm (p-value < 0.0432). For patients with LVI (N=77), 13 of 14 (93%) had < 4 positive ALN if the SLN metastasis size was ≤ 0.2cm (p < .0014). The highest prevalence of ≥ 4 positive ALN were patients with LVI and a SLN metastasis size > 0.2cm. Conclusions: The CHAID analysis more accurately predicted patients with < 4 positive ALN compared to those with ≥4. The decision tree provides a new tool for the clinician to determine the necessity for RNI without ALND. No significant financial relationships to disclose.

Abstract
UNLABELLED The functional status and health-related quality of life (HRQOL) of children who survive liver transplantation (LT) have not been well documented. The purpose of this study was to determine the functional status and HRQOL in this population using a validated measure for children, the Child Health Questionnaire-Parent Form 50 (CHQ-PF50). METHODS The CHQ-PF50 instrument was completed by the parents of 55 children who agreed to participate in a mailing survey. Subscale scores for the sample were compared with those of a published normal population (n = 391). RESULTS Study sample characteristics were: 87% Caucasian, 54.5% female, mean age at survey was 9.6 years (range, 5-17 years). Responding caregivers were 95% biologic parents and 93% female. Compared with the normal population, LT recipients had lower subscale scores for general health perceptions (P < 0.0005), emotional impact on parents (<0.0005) and disruption of family activities (0.0005). The mean physical summary score of the LT recipients was lower than that of the normal population 48.1 +/- 12.1 (P = 0.005), but the mean psychosocial summary score was similar 48.8 +/- 11.9 (P = 0.156). Within the LT population, the original diagnosis (biliary atresia vs. other), type of LT (living donor vs. cadaveric), age at LT, z score for height, and hospital days did not significantly influence any of the subscale scores. CONCLUSIONS Children who have survived LT have functional outcomes in the physical domain that are lower than those of normal children. Self-esteem and mental health in this group appeared normal. The parents in this sample experienced more emotional stress and disruption of family activities than did parents in a normal population.

Abstract
We present the first measurement of pseudorapidity densities of primary charged particles near midrapidity in Au+Au collisions at sqrt[s(NN)] = 56 and 130 GeV. For the most central collisions, we find the charged-particle pseudorapidity density to be dN/deta|(|eta|<1) = 408+/-12(stat)+/-30(syst) at 56 GeV and 555+/-12(stat)+/-35(syst) at 130 GeV, values that are higher than any previously observed in nuclear collisions. Compared to proton-antiproton collisions, our data show an increase in the pseudorapidity density per participant by more than 40% at the higher energy.

Abstract
OBJECTIVE To evaluate demographic and clinical characteristics, duration of time between disease onset (date of first rash and/or weakness), and diagnosis/therapy, as well as socioeconomic status, of children with newly diagnosed juvenile dermatomyositis (JDM). METHODS Structured telephone interview of families of a cohort of 79 children with JDM: interval between onset of symptoms to diagnosis, median of 3 months (range 0.5-20.0). RESULTS At diagnosis, all the children had rash (100%) and proximal muscle weakness (100%); 58 (73%) had muscle pain; 51 (65%) fever; 35 (44%) dysphagia; 34 (43%) hoarseness; 29 (37%) abdominal pain; 28 (35%) arthritis; 18 (23%) calcinosis, and 10 (13%) melena. Muscle derived enzymes were normal in 10% of the children. Of the 43 children who had an electromyogram (EMG), 8 (19%) had normal results. Fifty-one children had a muscle biopsy; the results were normal/nondiagnostic in 10 (20%). Median time from disease onset to diagnosis was different between racial groups: Caucasians (n=59) 2.0 months: for minorities (n=20), 6.5 months, (p=0.0008). The median time from disease onset to therapy was: Caucasians. 3.0 months; minorities, 7.2 months (p=0.002). Report of calcinosis was associated with increased time to diagnosis and therapy (p=0.04). In the 33 children whose first symptom occurred in June-September, rash preceded or accompanied onset of muscle weakness in 83% (n=27). Ninety-one percent of the children were given steroid therapy and 9% received methotrexate as well. CONCLUSION The results of an undirected site for muscle biopsy or EMG may not be diagnostic. Minority children had a longer interval between first JDM symptom and diagnosis/therapy than Caucasian children. Delay in diagnosis/therapy was associated with calcinosis.

Abstract
OBJECTIVE To determine, in a case-control study, if patients with new-onset juvenile dermatomyositis (juvenile DM) have increased symptoms prior to onset, exposure to certain environmental conditions, frequency of familial autoimmune diseases, or antibody titers, compared with 2 control groups. METHODS A structured interview with the families of 80 children with juvenile DM, 40 children with juvenile rheumatoid arthritis (JRA), or 23 healthy children, from the same geographic area as the children with juvenile DM, was conducted. All children's sera were tested for antibody to Toxoplasma gondii, herpes simplex virus (HSV), or coxsackievirus B (CVB). RESULTS A high proportion of children with juvenile DM had constitutional symptoms 3 months before the disease-onset date (P = 0.013 versus control children). Children with JRA had more relatives with rheumatoid arthritis (P = 0.0001) and pernicious anemia (P = 0.003) than did children with juvenile DM or healthy children. Among children < or =7 years of age, elevated enteroviral titers were more frequent in those with juvenile DM (81%) and in healthy controls (90%) than in those with JRA (64%), suggesting a common environmental exposure. Titers to T gondii, HSV, or CVB 1-6 were normal. CONCLUSION Frequencies of familial autoimmune disease, exposure to environmental factors, or elevated antibody titers to T gondii, HSV, or CVB are not increased in juvenile DM. Children with juvenile DM do have symptoms of illness 3 months before the disease-onset date, and young patients have elevated enteroviral titers, as do young geographic controls.

Abstract
The objective was to assess whether the aging related, variable decline in growth hormone influences total knee replacement outcome. In this prospective cohort study, consecutive patients who underwent unilateral total knee replacement and who met criteria were enrolled from the practice of 1 orthopaedic surgeon at a university hospital. Participants were evaluated 1 month before and 3 months after total knee replacement. Evaluators were not involved in patient care. The primary outcome measure was the Medical Outcome Study 36-item Short Form Health Survey Physical Functioning Scale score 3 months after total knee replacement. In a multiple regression analysis performed to assess the influence of growth hormone status, controlling for social support, body mass index, gender, previous reconstruction, mental health, motivation, and baseline physical functioning, only mental health contributed significantly to outcome. Mental health accounted for 18% of outcome variance. Growth hormone levels did not predict functional status after total knee replacement. Psychological status contributes significantly to total knee replacement physical functional outcome.

Abstract
BACKGROUND The objective was to investigate whether baseline physical functioning, medical, psychosocial, or demographic variables predict functional outcome in patients undergoing total knee replacement. METHODS A prospective cohort study was performed between December 1991 and August 1993. Consecutive, unilateral tricompartmental total knee replacement patients aged > or = 55 yr with osteoarthritis, who met criteria, were enrolled and evaluated one month before and 3 months after total knee replacement. The primary outcome measure was the Medical Outcome Study 36 Item Short Form Health Survey (known as the SF36) Physical Functioning Scale score. The outcome evaluator was not involved in patient care. RESULTS A hierarchical multiple regression analysis was performed to calculate the contribution of baseline variables to TKR outcome. Of the 27% of outcome variance explained by the model, demographic variables accounted for 4%, psychosocial variables (motivation, role functioning-emotional, and social functioning) for 19% (p = .013), medical variables (previous reconstruction, comorbidity, body mass index, bodily pain) for 2%, and baseline physical function for 2%. CONCLUSIONS Psychosocial variables are significantly related to total knee replacement functional outcome. Assessment of baseline psychological and social functioning may identify a subset of patients at risk for worse outcome. Specific interventions for these patients should be developed and evaluated as components of patient management prior to and after the procedure.

Abstract
OBJECTIVE Retroviruses can cause immunoregulatory disturbances and may play a role in the pathogenesis of autoimmune disorders. Little is known about the frequency of behavioral risk factors for exogenous retroviral infections in patients with autoimmune diseases. We compare the frequency of recognized risk factors for retroviral infections among patients with systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and controls. METHODS Patients with SLE and RA from a university rheumatology clinic and control patients were enrolled in this study. The presence of retroviral risk factors (intravenous drug use, prostitution, increased number of sex partners, sexually transmitted diseases, high risk sex partners, blood transfusion) was determined by a self-administered questionnaire. RESULTS We surveyed 81 patients with SLE and 117 with RA and 100 healthy controls. Patients in all groups reported similar exposure to all risk factors surveyed for retroviral infection except sexually transmitted disease, which was reported more often in patients with SLE (25% of SLE versus 11% of RA and 11% of controls, p = 0.013). CONCLUSION Self-reported retroviral risk factors were generally not increased in patients with autoimmune disease compared to healthy controls; the role of exogenous retroviruses in the pathogenesis of SLE and RA remains unclear.

Abstract
OBJECTIVE To define the clinical spectrum and disease sequelae of herpes zoster and to determine the risk factors associated with the development of herpes zoster in patients with systemic lupus erythematosus (SLE). METHODS Retrospective matched case control study in a consecutive series of patients with SLE first evaluated between 1979 and 1989. Patients were classified as cases if their first episode of zoster occurred after lupus diagnosis. Lupus patients who never had zoster were eligible as controls and were matched 2:1 to cases for age, race, sex, and survival status. Clinical features of the cases from the time of lupus diagnosis to the time of zoster were compared to their respective controls over similar time periods. RESULTS Forty eight (15%) of 321 patients were classified as cases. Cases were more likely to have received cyclophosphamide (p = 0.03), and azathioprine (p = 0.006). More cases had lupus nephritis (p = 0.02), and a concurrent or previous malignancy (p = 0.01) than their controls. Seven cases had cutaneous dissemination. Seven patients had postherpetic neuralgia > 2 months and in only 2 patients symptoms persisted for > 12 months' duration. Only 3 of 36 patients had immunosuppressive medication discontinued at the time of diagnosis of zoster, and 10 cases received acyclovir for the zoster infection. There were no permanent neurologic deficits or death. CONCLUSION Immunosuppressive therapy, specifically cyclophosphamide and azathioprine, lupus nephritis, and a concurrent or previous malignancy may be risk factors for the development of herpes zoster infections in patients with SLE. Our study suggests that although herpes zoster occurs frequently in patients with SLE, it has a relatively benign course. Discontinuing needed immunosuppressive therapy in patients with SLE may be unnecessary in the setting of a zoster infection. With the current emphasis on reduction in medical costs, both by limiting inpatient admissions and eliminating unneeded medications, it is necessary to identify which patients require more intensive therapy with antiviral medications and/or hospitalization and which are likely to have a benign, self-limited course without intervention.

Abstract
Little attention has been paid to evaluating the use of DSM-III-R with preschool children. Children (N = 510) ages 2 to 5 years who were screened at the time of a pediatric visit were selected to participate in an evaluation which included questionnaires, a semistructured interview, developmental testing, and a play observation. Following the evaluation, two clinical child psychologists independently assigned DSM-III-R diagnoses. For each diagnostic category, kappa and Y coefficients were calculated; Y coefficients are less sensitive to base rates of disorders. For overall agreement, the weighted mean kappa (.61), and mean Y (.66) were moderately high. Overall agreement that the child had at least one of the disruptive disorders was substantial (kappa = .64; Y = .65); agreement that there was at least one of the emotional disorders was moderate for kappa (.54), but substantial for Y (.70). Kappa coefficients were higher for major categories of disorder than for specific disorders; however, Y coefficients did not show a decline for specific disorders. Interrater reliability of DSM-III-R appears to be similar for preschoolers and older children.
