Abstract
Abstract
Background:
Exposure to trastuzumab for one year is an integral part of therapy for patients with early stage HER2-positive breast cancer. Yet, cardiac side effects, particularly in patients who also receive anthracyclines require frequent monitoring and result in dose interruptions and discontinuation of trastuzumab. Prophylactic use of angiotensin converting enzyme (ACE) nhibitors or beta blockers (BB) may prevent cardiotoxicity associated with chemotherapy and trastuzumab.
Methods
A large community-based prospective double-blind, placebo-controlled trial, evaluated the rates of pre-specified cardiotoxicity in patients with early stage breast cancer treated with one year of trastuzumab. Cardiac events were followed for two years. Patients were randomized to simultaneously receive either the ACE inhibitor, lisinopril, or the BB, carvedilol, or placebo and were further stratified by anthracycline use to determine whether ACE inhibitors or BB can prevent trastuzumab-induced decrease in left ventricular ejection fraction (LVEF) and trastuzumab interruptions.
Results:
The study included 468 eligible patients (median age:51, BMI:27 kg/m2, baseline systolic BP: 126mmHg and LVEF :63 ± 6.29%) from 127 community-based practices, 189 patients received an anthracycline. For the entire study population and the non-anthracycline group, no difference in number of trastuzumab interruptions were seen. For patients receiving an anthracycline, cardiac event rates were higher in the placebo group (47%), and reduced in both the lisinopril (37%), and the carvedilol (31%) groups. Interruptions of trastuzumab were required in 23% patients on lisinopril and 20% on carvedilol compared to 40% on placebo (p=0.007). Changes in LVEF from baseline (least square means, SE) were significantly reduced with both carvedilol (-4.5 (0.8), p=0.008, and lisinopril (-4.0 (0.8), p=0.002) than placebo, (-7.7 (0.8). Cardiotoxicity-free survival was longer on both carvedilol (hazard ratio 0.49, 95% confidence intervals 0.27, 0.89, p=0.009) or lisinopril (HR 0.53, CI 0.30, 0.94, p=0.015).
Conclusions
In patients with HER2-positive breast cancer receiving trastuzumab and an anthracycline, both lisinopril and carvedilol during treatment reduced cardiotoxicity in patients, but not in those with non-anthracyline containing regimens. The use of lisinopril or carvedilol may allow the use of an anthracycline without compromising trastuzumab treatment in those who might benefit from an anthracycline.

Abstract
OBJECTIVE There are variable reports of risk of concordance for progression to islet autoantibodies and type 1 diabetes in identical twins after one twin is diagnosed. We examined development of positive autoantibodies and type 1 diabetes and the effects of genetic factors and common environment on autoantibody positivity in identical twins, nonidentical twins, and full siblings. RESEARCH DESIGN AND METHODS Subjects from the TrialNet Pathway to Prevention Study (N = 48,026) were screened from 2004 to 2015 for islet autoantibodies (GAD antibody [GADA], insulinoma-associated antigen 2 [IA-2A], and autoantibodies against insulin [IAA]). Of these subjects, 17,226 (157 identical twins, 283 nonidentical twins, and 16,786 full siblings) were followed for autoantibody positivity or type 1 diabetes for a median of 2.1 years. RESULTS At screening, identical twins were more likely to have positive GADA, IA-2A, and IAA than nonidentical twins or full siblings (all P < 0.0001). Younger age, male sex, and genetic factors were significant factors for expression of IA-2A, IAA, one or more positive autoantibodies, and two or more positive autoantibodies (all P ≤ 0.03). Initially autoantibody-positive identical twins had a 69% risk of diabetes by 3 years compared with 1.5% for initially autoantibody-negative identical twins. In nonidentical twins, type 1 diabetes risk by 3 years was 72% for initially multiple autoantibody-positive, 13% for single autoantibody-positive, and 0% for initially autoantibody-negative nonidentical twins. Full siblings had a 3-year type 1 diabetes risk of 47% for multiple autoantibody-positive, 12% for single autoantibody-positive, and 0.5% for initially autoantibody-negative subjects. CONCLUSIONS Risk of type 1 diabetes at 3 years is high for initially multiple and single autoantibody-positive identical twins and multiple autoantibody-positive nonidentical twins. Genetic predisposition, age, and male sex are significant risk factors for development of positive autoantibodies in twins.

Abstract
OBJECTIVE A pilot study suggested that combination therapy with low-dose anti-thymocyte globulin (ATG) and pegylated granulocyte colony-stimulating factor (GCSF) preserves C-peptide in established type 1 diabetes (T1D) (duration 4 months to 2 years). We hypothesized that 1) low-dose ATG/GCSF or 2) low-dose ATG alone would slow the decline of β-cell function in patients with new-onset T1D (duration <100 days). RESEARCH DESIGN AND METHODS A three-arm, randomized, double-masked, placebo-controlled trial was performed by the Type 1 Diabetes TrialNet Study Group in 89 subjects: 29 subjects randomized to ATG (2.5 mg/kg intravenously) followed by pegylated GCSF (6 mg subcutaneously every 2 weeks for 6 doses), 29 to ATG alone (2.5 mg/kg), and 31 to placebo. The primary end point was mean area under the curve (AUC) C-peptide during a 2-h mixed-meal tolerance test 1 year after initiation of therapy. Significance was defined as one-sided P value < 0.025. RESULTS The 1-year mean AUC C-peptide was significantly higher in subjects treated with ATG (0.646 nmol/L) versus placebo (0.406 nmol/L) (P = 0.0003) but not in those treated with ATG/GCSF (0.528 nmol/L) versus placebo (P = 0.031). HbA1c was significantly reduced at 1 year in subjects treated with ATG and ATG/GCSF, P = 0.002 and 0.011, respectively. CONCLUSIONS Low-dose ATG slowed decline of C-peptide and reduced HbA1c in new-onset T1D. Addition of GCSF did not enhance C-peptide preservation afforded by low-dose ATG. Future studies should be considered to determine whether low-dose ATG alone or in combination with other agents may prevent or delay the onset of the disease.

Abstract
Essentials We evaluated antibody status, thromboembolism and survival after cardiac surgery. Positive antibody tests are common - over 50% are seropositive at 30 days. Seropositivity did not increase thromboembolism or impair survival after cardiac surgery. Results show heparin induced thrombocytopenia antibody screening after surgery is not warranted. SUMMARY Background Heparin-induced thrombocytopenia (HIT) is a prothrombotic response to heparin therapy with platelet-activating, anti-platelet factor 4 (PF4)/heparin antibodies leading to thrombocytopenia associated with thromboembolism. Objective We tested the hypothesis that anti-PF4/heparin antibodies are associated with thromboembolism after cardiac surgery. Methods This multicenter, prospective cohort study collected laboratory and clinical data up to 30 days after surgery and longer-term clinical follow-up data. The primary outcome variable combined new arterial or venous thromboembolic complications (TECs) with all-cause death until 90 days after surgery. Laboratory analyses included platelet counts and anti-PF4/heparin antibody titers (GTI ELISA), with a confirmatory excess heparin step and serotonin release assay. Chi-square testing was used to test the relationship between our outcome and HIT antibody seropositivity. Results Initially, 1021 patients were enrolled between August 2006 and May 2009, and follow-up was completed in December 2014. Seropositivity defined by OD > 0.4 was common, being almost 20% preoperatively, > 30% by discharge, and > 60% by day 30. Death (1.7% within 30 days) or TECs (69 in total) were more likely if the partient was seronegative (OD < 0.4), but positivity defined by OD > 1.0 or including an excess heparin confirmatory step resulted in equal incidence of death or TECs, whether the patient was seronegative or seropositive. Incorporating the serotonin release assay for platelet-activating antibodies did not alter these findings. Conclusions Seropositivity for anti-PF4/heparin antibodies does not increase the risk of death or thromboembolism after cardiac surgery. Screening is not indicated, and seropositivity should only be interpreted in the context of clinical evidence for HIT. TRIAL REGISTRATION Duke IRB Protocol #00010736.

Abstract
Purpose Osteogenesis imperfecta (OI) predisposes to recurrent fractures. The moderate-to-severe forms of OI present with antenatal fractures and the mode of delivery that would be safest for the fetus is not known. Methods We conducted systematic analyses on the largest cohort of individuals (n=540) with OI enrolled to-date in the OI Linked Clinical Research Centers. Self-reported at-birth fracture rates were compared in individuals with OI types I, III, and IV. Multivariate analyses utilizing backward-elimination logistic regression model building were performed to assess the effect of multiple covariates including method of delivery on fracture-related outcomes. Results When accounting for other covariates, at-birth fracture rates did not differ based on whether delivery was by vaginal route or by cesarean section (CS). Increased birth weight conferred higher risk for fractures irrespective of the delivery method. In utero fracture, maternal history of OI, and breech presentation were strong predictors for choosing CS for delivery. Conclusion Our study, the largest to analyze the effect of various factors on at-birth fracture rates in OI shows that delivery by CS is not associated with decreased fracture rate. With the limitation that the fracture data were self-reported in this cohort, these results suggest that CS should be performed only for other maternal or fetal indications, but not for the sole purpose of fracture prevention in OI.

Abstract
Nevus of Ota is a unilateral, asymptomatic cutaneous and mucosal hyperpigmentation of the face that is congenital or may appear during childhood. We present a case of symptomatic acquired nevus of Ota in an adult, associated with intense pruritus, not described in the literature so far. A 32-year-old woman presented with brownish mottled macules which appeared on her face progressively over 8 days, following the distribution of the first and second divisions of the left trigeminal nerve and partially covering the iris and sclera of the left eye. She reported an intense pruritus in this area. We performed a biopsy on the left forehead, which confirmed the diagnosis of nevus of Ota. Specific stains and immunohistochemistry revealed increased numbers of mast cells. Ophthalmological tests showed acute acquired melanocytosis of the left iris and sclera. The origin of the nevus is still unclear. Several hypotheses suggest a reactivation of melanocytes during their migration from the neural crest. The pruritus reported in our patient may be explained by the increased quantity of mast cells observed in the lesion and/or neuronal stimulation of the ophthalmic and maxillary divisions of the fifth cranial nerve.

Abstract
AIMS/HYPOTHESIS Viruses are candidate causative agents in the pathogenesis of autoimmune (type 1) diabetes. We hypothesised that children with a rapid onset of type 1 diabetes may have been exposed to such agents shortly before the initiation of islet autoimmunity, possibly at high dose, and thus study of these children could help identify viruses involved in the development of autoimmune diabetes. METHODS We used next-generation sequencing to search for viruses in plasma samples and examined the history of infection and fever in children enrolled in The Environmental Determinants of Diabetes in the Young (TEDDY) study who progressed to type 1 diabetes within 6 months from the appearance of islet autoimmunity, and in matched islet-autoantibody-negative controls. RESULTS Viruses were not detected more frequently in plasma from rapid-onset patients than in controls during the period surrounding seroconversion. In addition, infection histories were found to be similar between children with rapid-onset diabetes and control children, although episodes of fever were reported less frequently in children with rapid-onset diabetes. CONCLUSIONS/INTERPRETATION These findings do not support the presence of viraemia around the time of seroconversion in young children with rapid-onset type 1 diabetes.

Abstract
The feasibility to detect lactobacilli in mail-in infant stools collected monthly from 3-18 months old children was investigated. The aim was to determine total lactobacilli and Lactobacillus plantarum (L. plantarum) content (ng/g feces) in 50 infants each from Colorado (648 samples), Finland (624 samples) and Sweden (685 samples) who participated in the TEDDY (The Environmental Determinants of Diabetes in the Young) study. Total lactobacilli content varied markedly between 5 and 16,800 ng/g feces in the three clinical sites within and between individuals especially in infants. L.plantarum also varied markedly intra- and inter-individually from <0.5 - 736 ng/g feces. A higher variability of total lactobacilli was found before 10 months of age than after in the three different clinical sites. Sweden had the lowest total lactobacilli content compared to Colorado and Finland while the L.plantarum content was higher in Sweden. Mail-in stool samples from infants should prove useful in analyzing probiotics in childhood.

Abstract
AIMS Evaluate the reproducibility and relationship of various metabolic tests conducted as part of the Diabetes Prevention Trial-type 1 diabetes. METHODS Coefficients of variation, intraclass correlation coefficients, and Pearson correlations between the same metabolic tests performed at different times as well as the different tests were determined. RESULTS Fasting samples on the same day had a coefficient of variation of < 10 for C-peptide, 11 for insulin, and 2 for glucose. Testing on separate days approximately doubled the variance. Stimulated insulin values had less variance than fasting values and there was only a moderate correlation between fasting and stimulated values on each test. While highly correlated, C-peptide values from mixed meal tolerance tests are significantly lower than that obtained during oral glucose tolerance tests (OGTTs). Neither peak nor area under the curve C-peptide on the oral glucose tolerance test was different between those with abnormal and normal glucose tolerance. Those with abnormal as compared with normal glucose tolerance had lower 30-min C-peptide and a longer time to peak C-peptide. CONCLUSIONS A large, multi-centre trial, with tests performed over a decade-long period, can provide robust data. C-peptide data from oral glucose tolerance tests and mixed meal tolerance tests differ; therefore, the same stimulation test should be used to evaluate changes in beta cell function over time. Worsening glucose tolerance is associated with lower C-peptide at 30 min and a delay in peak secretion on the oral glucose tolerance test. This Diabetes Prevention Trial-type 1 diabetes data can be used in planning parameters for future studies, including evaluation of new algorithms to determine risk of disease.

Abstract
AIM The clinical relevance of sentinel lymph node (SLN) analysis was evaluated prospectively and compared with other known risk factors of relapse in early stage melanoma. METHODS Surgery was guided by lymphoscintigraphy, blue dye and gamma probe detection. SLN were analysed by haematoxylin eosin (HE) histochemistry and multimarker immunohistochemistry (IHC). Disease free survival (DFS) was evaluated with Kaplan-Meier plots according to different parameters and Cox analyses of variance. RESULTS From 210 patients a total of 381 SLN were excised. Lymphoscintigraphy identified all excised SLN with only 2 false positive lymphatic lakes. Fifty patients (24%) had tumour positive SLN. With a mean follow-up of 31.3 months, 29 tumour recurrences were observed, 19 (38%) in 50 SLN positive and 10 (6%) in 160 SLN negative patients. Strong predictive factors for early relapse (p < 0.0005) were SLN positivity and a high Breslow index. CONCLUSION SLN tumour positivity is an independent factor of high risk for early relapse with a higher power of discrimination than the Breslow index.

Abstract
AIMS/HYPOTHESIS Immunological and genetic markers can be used to assess risk of developing type 1 diabetes prior to the onset of clinical symptoms. Autoantibody-positive relatives of patients with type 1 diabetes are at increased risk for disease, while the presence of HLA DQA1*0102/DQB1*0602 is thought to confer protection. Using the unique population identified by the Diabetes Prevention Trial--Type Diabetes (DPT-1), our aim was to determine if these individuals were protected from type 1 diabetes. METHODS We described metabolic and immunological characteristics of islet cell cytoplasmic autoantibodies-positive relatives with DQB1*0602 identified as part of DPT-1. RESULTS We found that 32% of DQB1*0602-positive relatives identified through the DPT-1 had abnormalities of glucose tolerance despite the fact that only 19% had multiple type 1 diabetes-associated autoantibodies and only 13% had abnormal insulin secretion, markers typically associated with the disease. In addition, these markers were not associated with abnormal glucose tolerance. In contrast, the DQB1*0602-positive relatives had elevated fasting insulin (117+/-10 pmol/l) and homeostasis model assessment of insulin resistance (HOMA-R) (4.90+/-0.5) values, which are more commonly associated with type 2 diabetes. The later marker of insulin resistance was associated with glucose tolerance status. CONCLUSIONS/INTERPRETATION Our data indicate that DQA1*0102/DQB1*0602 relatives identified through DPT-1 have a high frequency of abnormal glucose tolerance and a disease phenotype with characteristics of type 1 and type 2 diabetes. Thus, multiple pathways to abnormal glucose tolerance are present within families of these type 1 patients.

Abstract
One of the main problems in the management of congenital nevi is the potential risk for malignant transformation and the resulting need for follow-up examination. Dermoscopy is a noninvasive technique that has been shown to be useful for the follow-up of benign melanocytic skin lesions as well as the early diagnosis of malignant melanoma. Therefore we thought to use the digital dermoscopy (DD) technique for the follow-up of congenital nevi. For documentation purposes we registered an overview, and the following standardized dermoscopic images of every lesion: representative architectural pattern, border of the lesion, and regions of "special interest." In all instances the examination with digital dermoscopy was well tolerated by the patients and the integration of the parents to the "live" examination on the computer screen was appreciated. The follow-up was easy to perform with these standardized documents. We showed the feasibility of follow-up of congenital nevi using digital dermoscopy. Furthermore, we identified three different patterns as well as some typical structures seen in congenital nevi by DD.

Abstract
Infections with mycobacteria are of importance in the differential diagnosis of skin lesions in immunocompromised patients. We report the case of a human immunodeficency virus (HIV)-infected patient who presented with an annular plaque as cutaneous manifestation of Mycobacterium haemophilum. Improvement of the immunologic status is important for successful treatment. Complete resolution was only observed when the antimycobacterial therapy was combined with antiretroviral therapy.

Abstract
BACKGROUND Herpes simplex virus (HSV) can produce persistent mucocutaneous disease in patients with the acquired immunodeficiency syndrome (AIDS). In this case report, we evaluate the efficacy, safety and viral resistance after topical foscarnet in severe genital ulceration due to acyclovir-resistant HSV-2. CASE REPORT A 45-year-old African woman was known for an HIV infection with severe immunosuppression (CD4 <100/mm3). She had received a long-term prophylaxis with acyclovir (400 mg b.i.d.) for a recurrent genital herpes. Few weeks after stopping this prophylaxis, she developed large genital ulcerations progressing despite valacyclovir treatment (1,000 mg t.i.d.). Cultures were positive for HSV-2, resistance to acyclovir was shown by the plaque reduction assay and topical foscarnet was tried. Treatment consisted of a 20-min application of topical foscarnet 2.4% twice a day. Dramatic improvement was observed with rapid antalgia, and cicatrization of the genital ulcerations was observed after 50 days. HSV could not be detected on the mucosal surface. Initially, HSV-2 was resistant to acyclovir but sensitive to foscarnet. After 1 month of topical treatment, HSV-2 became sensitive to acyclovir and was still sensitive to foscarnet. Finally, after 6 weeks of treatment, no virus could be detected by culture. CONCLUSION Topical foscarnet (2.4%) is a convenient treatment for chronic genital herpes. Resistance to acyclovir disappears few weeks after stopping this drug and sensitivity to foscarnet persists during the 50 days of treatment.

Abstract
PURPOSE To evaluate prospectively the effects on survival, relapse-free survival, and patterns of relapse of reduced-dose (23.4 Gy in 13 fractions) compared with standard-dose (36 Gy in 20 fractions) neuraxis irradiation in patients 3 to 21 years of age with low-stage medulloblastoma, minimal postoperative residual disease, and no evidence of neuraxis disease. PATIENTS AND METHODS The Pediatric Oncology Group and Children's Cancer Group randomized 126 patients to the study. All patients received posterior fossa irradiation to a total dose of 54 Gy in addition to the neuraxis treatment. Patients were staged postoperatively with contrast-enhanced cranial computed tomography, myelography, and CSF cytology. Of the registered patients, 38 were ineligible. RESULTS The planned interim analysis that resulted in closure of the protocol showed that patients randomized to the reduced neuraxis treatment had increased frequency of relapse. In the final analysis, eligible patients receiving standard-dose neuraxis irradiation had 67% event-free survival (EFS) at 5 years (SE = 7.4%), whereas eligible patients receiving reduced-dose neuraxis irradiation had 52% event-free survival at 5 years (SE = 7.7%) (P =.080). At 8 years, the respective EFS proportions were also 67% (SE = 8.8%) and 52% (SE = 11%) (P =.141). These data confirm the original one-sided conclusions but suggest that differences are less marked with time. CONCLUSION Reduced-dose neuraxis irradiation (23.4 Gy) is associated with increased risk of early relapse, early isolated neuraxis relapse, and lower 5-year EFS and overall survival than standard irradiation (36 Gy). The 5-year EFS for patients receiving standard-dose irradiation is suboptimal, and improved techniques and/or therapies are needed to improve ultimate outcome. Chemotherapy may contribute to this improvement.

Abstract
BACKGROUND Since devices for digital epiluminescence microscopy and for telemedicine have become affordable, a critical evaluation of this new method has been needed. OBJECTIVE Our aim was a critical evaluation of teledermatoscopy under routine conditions in private practice. METHODS Pigmented skin lesions (PSLs) scheduled for excision were documented with a digital epiluminescence microscopy (DELM) system. Images were sent to the PSL consultation at the Department of Dermatology of the University Hospital Geneva, where a diagnosis was established. The histopathologic report including the initial diagnosis was sent afterward. Both approaches were compared concerning diagnostic accuracy. RESULTS Over a period of 6 months, 55 lesions on 51 patients have been included in this study. Picture quality was good or very good in more than 90%. Diagnostic accuracy of the teledermatoscopy approach was superior to that of the conventional approach for malignant melanocytic lesions. CONCLUSION We have shown the feasibility of a teledermatoscopic consultation. The gain of diagnostic accuracy in this teledermatoscopic approach, especially for malignant melanocytic lesions, suggests that patients might benefit directly from such a consultation at distance.

Abstract
Since the 'renaissance' of epiluminescence microscopy (ELM), histological correlation of ELM structures has been the subject of many investigations. Direct correlation is difficult because of the methodological differences between ELM and histopathology. In order to further understand the features of pigmented skin lesions (PSLs), we studied whether hypoluminescence microscopy (HLM) had any advantages over ELM. Twenty pigmented skin lesions scheduled for surgical excision were chosen randomly for this study. After excision, the lesions were studied using standard ELM and an HLM technique. For the latter, illumination was performed from the dermal side. The HLM pattern was clearly different from that of ELM. In all lesions the 'deeper' (dermal) structures became more visible. Some structures already visible in ELM appeared more visible, particularly structures apparently localized in deeper layers of the PSL. For highly pigmented lesions the difference in the two approaches was striking. With the HLM technique details became visible, and structures which were hardly or not visible with the classic ELM approach could be easily distinguished and evaluated. In conclusion, HLM is a simple, easy to use, reproducible ex vivo technique that is able to provide additional information to the conventional ELM technique.

Abstract
The role of Malassezia spp in seborrheic dermatitis (SD) is controversial. To compare the cutaneous density and the cultural characteristics of Malassezia in persons with or without SD, quantitative cultures were obtained by stripping the forehead with a tape placed on Leeming and Notman medium. Plates were incubated at 37 degrees C in a plastic bag, and colonies were counted after 14 days. High yeast density was defined as > 100 colony forming units (CFU)/tape. Volunteers were divided into four groups depending on their HIV serology [HIV (+) versus HIV (-) or unknown] and their clinical status (with or without SD). 126/129 cultures were positive (97.7%). Malassezia spp density was low on clinically normal skin in all HIV (-) persons (40/40) but was high in 8/34 (24%) HIV (+) persons without SD (p < 0.001). In SD patients, high densities were found in 10/22 (45%) HIV (+) and in 17/33 (52%) HIV (-) persons. The strains could be divided into three basic groups on the basis of their cultural characteristics. Colony morphology type A predominated on normal skin (72%), and morphology type C predominated on persons with SD (78%). High yeast density can be present without skin symptoms. The pathogenicity of Malassezia seems more likely to be determined by the subtype present on the skin rather than by its density.

Abstract
We report here our prospective study of 15,224 non-diabetic, first-degree relatives of probands with immune-mediated (type 1) diabetes (IMD), of which 135 were found to eventually develop diabetes. We determined islet cell, insulin, GAD65, insulinoma-associated antigen-2 and 2beta autoantibodies (ICA, IAA, GAD65A, IA-2A and IA-2betaA), on the first available serum samples. The latter three autoantibodies were however assayed on subsets of the relatives with and without ICA, IAA and/or GAD65A, plus most of the relatives who developed diabetes. Of the relatives who progressed to diabetes, 94% had at least one of these autoantibodies on the first screening, while ICA proved to be the most sensitive single marker (sensitivity 74%). Risk of diabetes was however negligible when ICA was found in the absence of the others (5-year risk=5.3%), but increased dramatically whenever two or more autoantibodies were present (5-year risk=28.2% and 66.2%, respectively). The most predictive combination of markers was ICA plus IA-2A and/or IA-2beta A. Loss of first phase insulin release to IVGTT also occurred only in those ICA-positive relatives who had one or more of the other autoantibodies. The data suggests that significant beta-cell damage is seen only when the underlying autoimmunity has spread to multiple antigenic islet cell determinants. Combinations of the autoantibodies occurred most often in relatives with the highest risk HLA-DR/DQ phenotypes. These data document that only relatives positive for at least two or more of these five autoantibodies are at significant risk of diabetes themselves. Intervention trials for the prevention of type 1 diabetes could be designed based on testing for these autoantibodies alone, without the need for HLA typing and IVGTT testing.

Abstract
PURPOSE We evaluated the response to Temodal (Schering-Plough Research Institute, Kenilworth, NJ) of patients with newly diagnosed malignant glioma, as well as the predictive value of quantifying tumor DNA mismatch repair activity and O6-alkylguanine-DNA alkyltransferase (AGT). PATIENTS AND METHODS Thirty-three patients with newly diagnosed glioblastoma multiforme (GBM) and five patients with newly diagnosed anaplastic astrocytoma (AA) were treated with Temodal at a starting dose of 200 mg/m2 daily for 5 consecutive days with repeat dosing every 28 days after the first daily dose. Immunochemistry for the detection of the human DNA mismatch repair proteins MSH2 and MLH1 and the DNA repair protein AGT was performed with monoclonal antibodies and characterized with respect to percent positive staining. RESULTS Of the 33 patients with GBM, complete responses (CRs) occurred in three patients, partial responses (PRs) occurred in 14 patients, stable disease (SD) was seen in four patients, and 12 patients developed progressive disease (PD). Toxicity included infrequent grades 3 and 4 myelosuppression, constipation, nausea, and headache. Thirty tumors showed greater than 60% cells that stained for MSH2 and MLH1, with three CRs, 12 PRs, three SDs, and 12 PDs. Eight tumors showed 60% or less cells that stained with antibodies to MSH2 and/or MLH1, with 3 PRs, 3 SDs, and 2 PDs. Eleven tumors showed 20% or greater cells that stained with an antibody to AGT, with 1 PR, 2 SDs, and 8 PDs. Twenty-five tumors showed less than 20% cells that stained for AGT, with 3 CRs, 12 PRs, 4 SDs, and 6 PDs. CONCLUSION These results suggest that Temodal has activity against newly diagnosed GBM and AA and warrants continued evaluation of this agent. Furthermore, pretherapy analysis of tumor DNA mismatch repair and, particularly, AGT protein expression may identify patients in whom tumors are resistant to Temodal.

Abstract
BACKGROUND Early studies using HIV protease inhibitors (PI) showed regression of Kaposi's sarcoma (KS) lesions in some patients. OBJECTIVE Our purpose was to determine prospectively the influence of PI on HIV-related KS. METHODS KS lesions of nine patients with progressive cutaneous disease were prospectively evaluated clinically and by means of epiluminescence microscopy before and during PI therapy. HIV viremia and CD4 cell count were measured in parallel. RESULTS All patients experienced reduction or initial stabilization of KS lesions during the first 4 to 8 weeks of HIV-1 PI therapy. After a median follow-up of 7 months and according to AIDS Clinical Trials Groups criteria, six patients had a partial response, two showed stable disease, and in one noncompliant patient KS progressed, requiring chemotherapy. With epiluminescence microscopy, a reduction in skin surface alterations, lesional size, and color intensity was demonstrated in six of nine patients. PI induced a median decrease in viremia of 1.66 log and a median increase in the CD4 count of 49 cells/mm3. CONCLUSION In this series, HIV PI therapy reduced or stabilized KS. The efficacy of HIV-1 PI in KS may result from the improvement in cellular immunity. These results suggest the use of PI in AIDS-related KS regardless of the level of CD4 lymphocyte count and HIV viremia.

Abstract
Neutrophilic eccrine hidradenitis (NEH), first described as a rare, transient, and benign complication of various chemotherapy regimens for acute leukemia, has also been observed in other conditions, including three HIV-positive patients and even in otherwise healthy individuals (1-3). A similar histological pattern was described after intradermal bleomycin injections into normal human skin (4). We report the first case of NEH in a hemophilic HIV infected patient treated with stavudine, a new reverse transcriptase inhibitor.

Abstract
BACKGROUND In vivo epiluminescent light microscopy (ELM) of pigmented skin lesions reveals numerous elementary structures. Among them, the pigment network (PN), black dots (BD) and brown globules (BG) constitute important semiologic features. Based on histological extrapolations, it has been postulated that PN should reflect the presence of melanin in the epidermis and its honeycomb aspect should result from the dermoepidermal architecture. OBJECTIVE To demonstrate this directly by analyzing separately by ELM the epidermal and dermal sides of melanocytic lesions. METHODS We split the epidermis from the dermis of 10 pigmented lesions (6 lentigos, 4 nevocytic nevi) by incubation with dispase. ELM images were done in vivo before excision, then ex vivo on the whole specimen and separately on the split epidermis and dermis. Epidermal and dermal specimens were finally controlled by histology. RESULTS PN was observed only on the epidermal side of the split. Its organization was remarkably conserved after the procedure as compared with prior in vivo images. In contrast, pigmentation observed on dermal sides of the splits showed no organized pattern and corresponded to melanophages. BG were found on the dermal side and BD on the epidermal side of the split lesions, which confirms previous hypotheses. CONCLUSION By subtracting the dermal pigmentation and vessels from the image, the split technique has thus established the epidermal origin of the PN and given a more detailed ELM analysis of network components.

Abstract
Knowledge about the link between folic acid supplementation in pregnancy and the prevention of neural tube defects was assessed in women from two contrasting general practices using a questionnaire. The persisting lack of awareness, particularly in the more at-risk group from the inner city area, lends support to the argument in favour of the fortification of flour.

Abstract
BACKGROUND Treatment by ultraviolet radiation (UV) during human immunodeficiency virus (HIV) infection is controversial, since exposure of HIV-infected cells in vitro to UV enhances HIV replication in vitro. METHODS Four consecutive AIDS patients with psoriasis and CD4 count lower than 20/mm3 were treated with 8-methoxypsoralen and UVA (PUVA). HIV viremia expressed as long of HIV-1 RNA copies/ml of plasma was quantified 10 min before and 1 h following UVA exposure, every week during PUVA therapy and at the end of treatment. The Psoriasis Area Surface Index (PASI) score was used to quantify the severity of psoriasis. RESULTS No significant change in HIV-1 RNA level was observed in the 18 paired samples analyzed before and 1 h after PUVA (median: -0.05 log HIV-1 RNA, range: -0.50-0.21, p = 0.10). After 12-31 UVA exposure for a total dose of 15.5-196 J/cm2 over a period of 6-15 weeks, viremia changes from baseline in the 4 patients were -0.61, -0.07, 0.36 and 0.39 log HIV RNA. In 1 patient without antiviral treatment, a persistent decrease in viremia and transient increase in CD4 cell count were observed. PUVA was well tolerated and associated with significant improvement of the PASI score in 3 patients. CONCLUSION HIV viremia is not significantly modified by PUVA therapy in AIDS patients with psoriasis.

Abstract
Following failure of conventional therapy for reflux oesophagitis, 15 children were treated with omeprazole 20 mg daily for a period of up to three months initially. Treatment resulted in a marked symptomatic improvement as measured by incidence of pain, vomiting, dysphagia and haematemesis. Four children failed treatment and required fundoplication. No complications from the use of omeprazole were recorded and some children have continued long-term treatment.

Abstract
BACKGROUND The value of autologous bone marrow transplantation in the treatment of children with acute myeloid leukemia (AML) is unknown. We compared autologous bone marrow transplantation with intensive consolidation chemotherapy as treatments for children with AML in first remission. METHODS We induced remission with one course of daunorubicin, cytarabine, and thioguanine, followed by one course of high-dose cytarabine (3 g per square meter of body-surface area for six doses). Patients in remission after the second course of induction therapy were eligible for randomization. Between June 1988 and March 1993, 552 of 649 enrolled patients who could be evaluated (85 percent) entered remission. A total of 209 patients were not eligible for randomization; of the remaining 343 patients, 232 were randomly assigned to receive six courses of intensive chemotherapy (117 patients) or autologous transplantation (115 patients). Of the original 649 patients, 189, including 21 with Down's syndrome, were nonrandomly assigned to receive intensive chemotherapy. RESULTS The rates of event-free survival and overall survival for the entire group at three years were 34 +/- 2.5 percent and 42 +/- 2.6 percent, respectively. For patients who were randomly assigned to one of the two treatment groups, the mean (+/- SE) rates of event-free survival three years after randomization were not significantly different in the two groups when examined by intention-to-treat analysis: 36 +/- 5.8 percent for the intensive-chemotherapy group as compared with 38 +/- 6.4 percent for the autologous-transplantation group; and the relative risk of treatment failure for the chemotherapy group as compared with the autologous-transplantation group was 0.81 (P = 0.20 by the log rank test; 95 percent confidence interval, 0.58 to 1.12). Overall survival at three years followed a similar pattern. There was a lower relapse rate (31 percent vs. 58 percent, P < 0.001) but a higher rate of treatment-related mortality (15 percent vs. 2.7 percent, P = 0.005) in the group treated with autologous transplantation than in the intensive-chemotherapy group. The event-free survival at three years for the nonrandomized intensive-chemotherapy group was 39 +/- 5.1 percent, and for a contemporaneous group of patients each of whom received a histocompatible bone marrow transplant from a sibling, it was 52 +/- 8.0 percent. CONCLUSIONS Treatment of children with AML in first remission with either autologous bone marrow transplantation or intensive chemotherapy prolongs event-free survival equally.

Abstract
PURPOSE A randomized study compared the combination of amsacrine (100 mg/m2/d on days 1 to 5) and etoposide (200 mg/m2/d on days 1 to 3) with the same two agents plus azacitidine (250 mg/m2/d on days 4 to 50) for the therapy of induction-resistant or relapse childhood acute myeloid leukemia (AML). PATIENTS AND METHODS One hundred sixty-seven assessable children with AML who either had failed to respond to primary induction therapy (group 1, n = 41) or had relapsed (group 2, n = 126) were randomized. RESULTS Overall, there were 56 complete responses (34%; SE 4%). Among primary refractory patients (group 1), the complete response rate was higher with the three-drug regimen (18% vs 53%, P = .03). In the relapsed patients (group 2), there was no difference in complete response rates related to treatment (31% vs 35%, P = .3). There were 17 early deaths. The major toxicities for both regimens were myelosuppression and infection. CONCLUSION The overall complete response rate of 34% in this patient population is indicative of effective antileukemic activity. For patients with relapsed leukemia, the addition of azacitidine to etoposide and amsacrine did not improve response. The suggested advantage of the three-drug regimen for induction failures warrants further investigation.

Abstract
PURPOSE To determine in a prospective randomized trial the effect on survival, progression-free survival, and patterns of relapse of a decrease in the neuraxis radiation dose from 3,600 cGy in 20 fractions to 2,340 cGy in 13 fractions in patients with newly diagnosed medulloblastoma between 3 and 21 years of age with low T stage (T1, T2 and T3A), minimal postoperative residual tumor, and no evidence of dissemination (M0). METHODS AND MATERIALS Between June 1986 and November 1990, the Children's Cancer Group and the Pediatric Oncology Group randomized 126 patients in a two-arm study comparing the two different doses of neuraxis irradiation. In both arms, the posterior fossa received 5,400 cGy in 30 fractions. All patients were staged with myelography, postoperative lumbar cerebrospinal fluid cytology, and postoperative contrast-enhanced cranial computerized tomography to ensure no evidence of dissemination and no more than 1.5 cm3 residual tumor volume. Overall survival, progression-free survival, and patterns of recurrence were carefully monitored. Prospective endocrine and psychometric studies were performed to determine the benefit of decreasing the neuraxis radiation dose. RESULTS Following an interim analysis at a median time on study of 16 months, the study was closed, since a statistically significant increase was observed in the number of all relapses as well as isolated neuraxis relapses in patients randomized to the lower dose of neuraxis radiation. CONCLUSIONS In patients with newly diagnosed medulloblastoma considered to have a good prognosis on the basis of low T stage, minimal residual tumor after at least subtotal resection, and no evidence of dissemination after thorough evaluation, there is an increased risk of early relapse associated with lowering the dose of neuraxis radiation from 3,600 cGy in 20 fractions to 2,340 cGy in 13 fractions.
