Reproducible assay results with high specificity and high PPV in a multicenter setting demonstrate that use of an assay to detect serum BG derived from fungal cell walls is a useful diagnostic adjunct for IFI.

The American College of Cardiology Adult Congenital and Pediatric Cardiology (ACPC) Section had attempted to create quality metrics (QM) for ambulatory pediatric practice, but limited evidence made the process difficult. The ACPC sought to develop QMs for ambulatory pediatric cardiology practice. Five areas of interest were identified, and QMs were developed in a 2-step review process. In the first step, an expert panel, using the modified RAND-UCLA methodology, rated each QM for feasibility and validity. The second step sought input from ACPC Section members; final approval was by a vote of the ACPC Council. Work groups proposed a total of 44 QMs. Thirty-one metrics passed the RAND process and, after the open comment period, the ACPC council approved 18 metrics. The project resulted in successful development of QMs in ambulatory pediatric cardiology for a range of ambulatory domains.

We studied the thyroid gland in 18 long term survivors of Hodgkin Disease, all of whom received radiation therapy (2400-4000 cGy, mean 3434). Evaluation included clinical examination, thyroid function tests, ultrasound, as well as selective use of nuclear scintigraphy. The time interval post radiation was 1-16 years (mean 6.4 years). Clinical evaluation and thyroid function tests were insensitive in detecting abnormalities and most nodules were non palpable. Ultrasound detected abnormalities in 16 patients (89%) including diffuse atrophy (n = 6), solitary nodules (n = 4), multiple nodules (n = 5) and gland heterogeneity with calcification in one patient. Cold nodules on nuclear scintigraphy (n = 4) were subjected to biopsy. Multiple foci of papillary carcinoma were found in one patient. There was a tendency for nodules to increase in number as the post radiation interval also increased. We recommend frequent sonographic evaluation and early suppression of thyroid stimulation in an attempt to arrest the development of neoplastic changes.

The predicted incidence of liveborn monozygotic trisomy 18 twins is one per million births. The first case of liveborn monozygotic trisomy 18 twins was reported in 1989 and we report a second case in which striking phenotypic discordance existed. The probability of monozygotic trisomy 18 twinning and the mechanisms for phenotypic discordance in trisomic twins is discussed. Case report A 26 year old white woman, gravida 2, para 1-0-0-1, with a twin pregnancy, was admitted to hospital at 27 weeks' gestation because of premature rupture of membranes and preterm labour. Ultrasonographic examination at this time showed discordant fetal measurements: biparietal diameters 71 and 60 mm, and femur lengths 48 and 44 mm (values for twin A and twin B, respectively). Twin A, who had fetal measurements appropriate for gestational age, had a two vessel umbilical cord and an umbilical artery blood velocity systolic/diastolic ratio (S/D ratio)= 2 5-3@1. Twin B had a "lemon shaped appearance of the fetal head" (fig la) and a cystic spine defect at the level of the lumbar vertebrae consistent with a

The role of gallium-67 in the differentiation between active disease and fibrotic changes in patients with childhood lymphoma involving the mediastinum and neck was evaluated prospectively. Ga-67 imaging and computed tomography (CT) were correlated with clinical findings at the time of initial presentation and follow-up in 19 patients. Both modalities enabled detection of active disease on all occasions, but CT results were false-positive for residual disease in 10 patients (53%), whereas Ga-67 imaging results were false-positive in only one patient (5%). Neither modality, however, proved accurate in patients with rebound thymic hyperplasia. Ga-67 imaging is a useful tool for assessing response to therapy in children with lymphoma of the mediastinum and neck.

Objective: To enhance the understanding of cardiovascular care delivery in childhood cancer patients and survivors. Study design: A 20-question survey was created by the Pediatric Cardio-oncology Work Group of the American College of Cardiology (ACC) Cardio-oncology Section to assess the care, management, and surveillance tools utilized to manage pediatric/young adult cardio-oncology patients. The survey distribution was a collaborative effort between Cardio-oncology Section and membership of the Adult Congenital and Pediatric Cardiology Section (ACPC) of the ACC. Results: Sixty-five individuals, all self-identified as physicians, responded to the survey. Most respondents (n = 58, 89%) indicated childhood cancer patients are regularly screened prior to and during cancer therapy at their centers, predominantly by electrocardiogram (75%), standard echocardiogram (58%) and advanced echocardiogram (50%) (i.e. strain, stress echo). Evaluation by a cardiologist prior to/during therapy was reported by only 8(12%) respondents, as compared to post-therapy which was reported by 28 (43%, p < 0.01). The most common indications for referral to cardiology at pediatric centers were abnormal test results (n = 31,48%) and history of chemotherapy exposure (n = 27,42%). Of note, during post-treatment counseling, common cardiovascular riskfactors like blood pressure (31,48%), lipid control (22,34%), obesity & smoking (30,46%) and diet/exercise/weight loss (30,46%) were addressed by fewer respondents than was LV function (72%). Conclusions: The survey data demonstrates that pediatric cancer patients are being screened by EKG and/or imaging prior to/during therapy at most centers. Our data, however, highlight the potential for greater involvement of a cardiovascular specialist for pre-treatment evaluation process, and for more systematic cardiac risk factor counseling in posttreatment cancer survivors.
