Abstract
Introduction Our previous studies have demonstrated that tumor-infiltrating lymphocytes (TILs), including normal B cells, T cells, and natural killer (NK) cells, in diffuse large B-cell lymphoma (DLBCL) have a significantly favorable impact on the clinical outcomes of patients treated with standard chemoimmunotherapy. In this study, to gain a full overview of the tumor immune microenvironment (TIME), we assembled a flow cytometry cohort of 102 patients diagnosed with DLBCL at the Duke University Medical Center. Methods We collected diagnostic flow cytometry data, including the proportion of T cells, abnormal B cells, normal B cells, plasma cells, NK cells, monocytes, and granulocytes in fresh biopsy tissues at clinical presentation, and analyzed the correlations with patient survival and between different cell populations. Results We found that low T cell percentages in all viable cells and low ratios of T cells to abnormal B cells correlated with significantly poorer survival, whereas higher percentages of normal B cells among total B cells (or high ratios of normal B cells to abnormal B cells) and high percentages of NK cells among all viable cells correlated with significantly better survival in patients with DLBCL. After excluding a small number of patients with low T cell percentages, the normal B cell percentage among all B cells, but not T cell percentage among all cells, continued to show a remarkable prognostic effect. Data showed significant positive correlations between T cells and normal B cells, and between granulocytes and monocytes. Furthermore, we constructed a prognostic model based on clinical and flow cytometry factors, which divided the DLBCL cohort into two equal groups with remarkable differences in patient survival and treatment response. Summary TILs, including normal B cells, T cells, and NK cells, are associated with favorable clinical outcomes in DLBCL, and flow cytometry capable of quantifying the TIME may have additional clinical utility for prognostication.

Abstract
The main deterrent to long-term space travel is the risk of Radiation Exposure Induced Death (REID). The National Aeronautics and Space Administration (NASA) has adopted Permissible Exposure Levels (PELs) to limit the probability of REID to 3% for the risk of death due to radiation-induced carcinogenesis. The most significant contributor to current REID estimates for astronauts is the risk of lung cancer. Recently updated lung cancer estimates from Japan's atomic bomb survivors showed that the excess relative risk of lung cancer by age 70 is roughly four-fold higher in females compared to males. However, whether sex differences may impact the risk of lung cancer due to exposure to high charge and energy (HZE) radiation is not well studied. Thus, to evaluate the impact of sex differences on the risk of solid cancer development post-HZE radiation exposure, we irradiated Rb fl/fl ; Trp53 fl/+ male and female mice infected with Adeno-Cre with various doses of 320 kVp X-rays or 600 MeV/n 56 Fe ions and monitored them for any radiation-induced malignancies. We observed that lung adenomas/carcinomas and esthesioneuroblastomas (ENBs) were the most common primary malignancies in X-ray and 56 Fe ion-exposed mice, respectively. In addition, 1 Gy 56 Fe ion exposure compared to X-rays led to a significantly higher incidence of lung adenomas/carcinomas (p=0.02) and ENBs (p<0.0001). However, we did not find a significantly higher incidence of any solid malignancies in female mice as compared to male mice, regardless of radiation quality. Furthermore, gene expression analysis of ENBs suggested a distinct gene expression pattern with similar hallmark pathways altered, such as MYC targets and MTORC1 signaling, in X-ray and 56 Fe ion-induced ENBs. Thus, our data revealed that 56 Fe ion exposure significantly accelerated the development of lung adenomas/carcinomas and ENBs compared to X-rays, but the rate of solid malignancies was similar between male and female mice, regardless of radiation quality.

Abstract
Acute myeloid leukemia (AML) is a heterogeneous hematologic malignancy characterized by the clonal expansion of myeloid blasts in the peripheral blood, bone marrow, and/or other tissues. It is the most common form of acute leukemia among adults and accounts for the largest number of annual deaths from leukemias in the United States. Like AML, blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a myeloid malignancy. It is a rare malignancy characterized by the aggressive proliferation of precursors of plasmacytoid dendritic cells that frequently involves the bone marrow, skin, central nervous system, and other organs and tissues. This discussion section focuses on the diagnosis and management of BPDCN as outlined in the NCCN Guidelines for AML.

Abstract
A wide variety of diseases are commonly diagnosed via the visual examination of cell morphology within a peripheral blood smear. For certain diseases, such as COVID-19, morphological impact across the multitude of blood cell types is still poorly understood. In this paper, we present a multiple instance learning-based approach to aggregate high-resolution morphological information across many blood cells and cell types to automatically diagnose disease at a per-patient level. We integrated image and diagnostic information from across 236 patients to demonstrate not only that there is a significant link between blood and a patient's COVID-19 infection status, but also that novel machine learning approaches offer a powerful and scalable means to analyze peripheral blood smears. Our results both backup and enhance hematological findings relating blood cell morphology to COVID-19, and offer a high diagnostic efficacy; with a 79% accuracy and a ROC-AUC of 0.90.

Abstract
CONTEXT.— Concomitant BCR-ABL1 and JAK2V617F in myeloproliferative neoplasms (MPNs) is rare, and its pathogenesis and clinical significance are unclear. OBJECTIVE.— To investigate the clonal relationship between the 2 genomic alterations, as well as the clinicopathologic impact. DESIGN.— Retrospective analysis of MPNs with sequential development of BCR-ABL1 and JAK2V617F. RESULTS.— Of 6 cases, 5 had JAK2V617F-positive MPN diagnosed before acquiring BCR-ABL1 years later, and 1 had BCR-ABL1+ chronic myeloid leukemia before JAK2V617F-positive myelofibrosis completely replaced the BCR-ABL1+ clone 1 year after tyrosine kinase inhibitor therapy. Among the former group, treatment for the initial MPN involved hydroxyurea, ruxolitinib, and/or supportive care, and the latency to the development of JAK2V617F ranged from 4 to 13 years (median of 9 years). Four cases showed retention of JAK2V617F, whereas BCR-ABL1 emerged as the major clone, including 2 that exhibited parallel increases in JAK2V617F and BCR-ABL1 burdens, with both genomic markers exceeding 50%. Three patients received stem cell transplants and demonstrated sustained engraftment, with the genomic markers below detectable levels. CONCLUSIONS.— Most MPNs with concomitant JAK2V617F and BCR-ABL1 are actually composite MPNs with a "second hit" residing on a different clone. Rare cases demonstrate a subclone harboring a "double-hit" in a background of a JAK2V617F-positive stem line clone. The probability of a "double-hit" with a BCR-ABL1+ stem line clone is probably reduced by effective tyrosine kinase inhibitor treatment. The treatment often involves combined kinase inhibitors and/or hydroxyurea, but the outcome is unpredictable; hematopoietic stem cell transplantation may be the ultimate therapeutic option for this complicated disease.

Abstract
10586 Background: Clonal hematopoiesis (CH) is the presence of expanded somatic clones in hematopoietic cells and is associated with higher overall mortality (OM). Studies suggest atherosclerotic cardiovascular disease may drive mortality, but the detailed mechanisms remain unclear. CH mutations can be detected in solid tumor sequencing, often confounding genomic tumor analysis. We evaluated the association of CH in solid tumor next-generation sequencing (NGS) with echocardiographic findings and OM. Methods: Sequential adult patients treated at the Duke Cancer Institute with solid tumor NGS analysis by FoundationOne were captured retrospectively. CH mutations present at a variant allele fraction ≥2% across 57 genes previously associated with hematologic malignancies were included. Patients with echocardiograms between 2 years before NGS testing and up to 5 years afterward were analyzed. Association between CH mutations with cardiomyopathy (CM, left ventricular ejection fraction < 45%) and global longitudinal strain (GLS) was determined using logistic and linear regression, respectively. In a subset of patients with detailed cancer diagnosis date and clinical follow-up, Cox proportional hazard models were used to associate CH mutations with OM, with or without TP53/ KRAS (included in most CH analyses but highly prevalent in solid tumors). Analyses were adjusted for age, gender and race. Results: Of 3029 patients with NGS testing, 2212 (73.0%) carried at least one CH related mutation, the majority of which were in TP53/ KRAS. When excluding TP53/ KRAS, CH mutations were observed in 806 of 3029 (26.6%) patients. CH mutations were associated with age (est 2.1, 95% CI 1.1-3.2, p < 0.001). Excluding TP53/ KRAS strengthened the association between CH and age (est 2.8, 95% CI 1.8-3.9, p < 0.001). Echocardiogram data were available in 828 patients, of whom 48 (5.8%) had CM. CH mutations were not associated with CM (OR 1.3, 95% CI 0.6-2.6, p = 0.5), however when excluding TP53 and KRAS, CH mutations were associated with lower odds of (OR 0.4, 95% CI 0.1-0.9, p = 0.03). GLS was available in 423 patients and was not associated with CH mutations (p = 0.8 with TP53/ KRAS; p = 0.4 without TP53/ KRAS as CH). In 222 patients with clinical information, OM did not differ between the CH vs no CH cohorts (HR 0.8, 95% CI 0.6 = 1.2, p = 0.3 inclusive of TP53/KRAS). When excluding TP53/ KRAS mutations, in this population of patients with cancer, non- TP53/ KRAS CH was associated with less OM (HR 0.6, 95% CI 0.4-0.9, p = 0.01). Conclusions: In this patient population with cancer, CH mutations did not associate with higher CM. In contrast to prior studies, CH detected in solid tumor does not associate with OM in this population. CH mutations confound tumor sequencing and these findings support the value of paired tumor-blood sequencing to determine true CH. Consensus around CH variants should be undertaken in future studies.

Abstract
The NCCN Guidelines for Acute Myeloid Leukemia (AML) provide recommendations for the diagnosis and treatment of adults with AML based on clinical trials that have led to significant improvements in treatment, or have yielded new information regarding factors with prognostic importance, and are intended to aid physicians with clinical decision-making. These NCCN Guidelines Insights focus on recent select updates to the NCCN Guidelines, including familial genetic alterations in AML, postinduction or postremission treatment strategies in low-risk acute promyelocytic leukemia or favorable-risk AML, principles surrounding the use of venetoclax-based therapies, and considerations for patients who prefer not to receive blood transfusions during treatment.

Abstract
The maintenance and propagation of complex mixtures of cells in vitro in the form of native organs or engineered organoids has contributed to understanding mechanisms of cell and organ development and function which can be translated into therapeutic benefits. For example, allogeneic cultured postnatal human thymus tissue has been shown to support production of naïve recipient T cells when transplanted into patients with complete DiGeorge anomaly and other genetic defects that result in congenital lack of a thymus. Patients receiving such transplants typically exhibit reversal of their immunodeficiency and normalization of their peripheral blood T cell receptor V-beta repertoire, with long-term survival. This study was designed to assess the histopathologic changes that occur in postnatal human thymus slices when cultured according to protocols used for transplanted tissues. Results showed that as thymic organ cultures progressed from days 0 through 21, slices developed increasing amounts of necrosis, increasing condensation of thymic epithelium, and decreasing numbers of residual T cells. The architecture of the thymic epithelial network remained generally well-preserved throughout the 21 days of culture, with focal expression of cytokeratin 14, a putative biomarker of thymic epithelial cells with long-term organ-repopulating potential. All organ slices derived from the same donor thymus closely resembled one another, with minor differences in size, shape, and relative content of cortex versus medulla. Similarly, slices derived from different donors showed similar histopathologic characteristics when examined at the same culture time point. Taken together, these results demonstrate that diagnostic criteria based on structural features of the tissue identifiable via hematoxylin and eosin staining and cytokeratin immunohistochemistry can be used to evaluate the quality of slices transplanted into patients with congenital athymia.

Abstract
Hematolymphoid neoplasms, including lymphoma and myeloid neoplasms, can occur in patients with sickle cell disease (SCD) or equivalent hemoglobinopathy, but an underlying connection between the two conditions has yet to be fully determined. Herein, we report a unique case of sequential development of two separate hematolymphoid neoplasms, human herpes virus 8 (HHV8)-positive diffuse large B-cell lymphoma (DLBCL) and chronic myelomonocytic leukemia, in a 59 year-old African American female with hemoglobin SC disease. While etiology of immunodeficiency is unknown, the potential causes include hydroxyurea therapy, disease related immunomodulation, chronic inflammation, and relatively old age. The leukemia cells demonstrated profound trilineage dysplasia and harbored complex cytogenetic abnormalities with loss of chromosome 5q and 7q, which are often observed in therapy-related myeloid neoplasms. Besides the potential causes listed above, we propose that myeloid leukemia in this setting may result from genomic changes due to excessive hematopoietic replication triggered by a hemolysis-induced cytokine storm. While myeloid neoplasms in the setting of SCD seems to herald a dismal clinical outcome per the literature, the HHV8-positive DLBCL in our case was apparently indolent, opposing the current perception of its clinical outcome.

Of five patients, three were female and two were male with a median age of 75 years at diagnosis of concurrent PCN-WM/LPL. Three cases presented with serum paraprotein of IgM type and had a diagnosis of WM/LPL before identifying concurrent PCN, with an interval of 1 to 10 years. In the remaining two cases, PCN and WM/LPL were concurrently diagnosed. All patients demonstrated biclonal M-spikes with distinct heavy chain isotypes but concordant light chain isotype (kappa or lambda) by immunofixation electrophoresis. In all four cases, two neoplastic populations were highlighted with immunohistochemistry, including expression of CD56/cyclin D1 (1), cyclin D1 (2), and IgA (1) in neoplastic plasma cells and negativity of CD56/cyclin D1 in LPL. Of three patients with clinical information available, two were treated with chemotherapy, and the other was treated with autologous stem cell transplant. At follow-up, one patient died of PCN progression at 24 months, one had recurrent WM/LPL at 144 months, and the other was alive with disease 5 months after the diagnosis of concurrent neoplasms.
Conclusion
Discordant heavy chain isotype restrictions between PCN and WM/LPL suggest biclonal B-cell neoplasms, which is supported by PCN’s phenotypic distinction, such as expression of cyclin D1 and/or CD56, from coexisting WM/LPL. However, our cases had WM/LPL either preceding or concurring with PCN, and all exhibited concordant light chain restrictions, raising a possibility that PCN may be evolved from WM/LPL with class switching. This issue of clonal relationship between the two B-cell neoplasm and underlying pathogenesis remains to be investigated with sequencing analysis on sorted PCN or WM/LPL and comparison of mutation profiles between them.

Abstract
Abstract
NKG2D is expressed on cytotoxic lymphocytes and is an important immunosurveillance receptor that recognizes stress ligands such as MICA on tumor cells or virally infected cells. Unlike traditional immune activating receptors, NKG2D couples to the non-ITAM-containing transmembrane adaptor DAP10, which recruits PI3K and Grb2 to initiate target cell lysis. Current understanding predicts an ITAM-independent mechanism of NKG2D-mediated cytotoxicity. However, we show that in primary human NK cells, the ITAM-containing adaptors DAP12, FcϵR1γ, and CD3ζ selectively regulate the Grb2-Vav1 branch of NKG2D-mediated signal transduction and cytotoxicity. Furthermore, this ITAM-adaptor regulation of NKG2D is independent of ITAM activation. Thus our data reveal a more complex interplay between NKG2D and other activating receptors than was previously imagined, and we have uncovered a novel mechanism of ITAM-adaptor regulation of cell-mediated cytotoxicity. A more thorough understanding of immunoreceptor signaling networks will lead to more precise therapies when fighting diseases such as cancer, autoimmunity, and infection.

Abstract
In connection with the CDC National Conference on Pfiesteria, a multidisciplinary panel evaluated Pfiesteria-related research. The panel set out what was known and what was not known about adverse effects of the organism on estuarine ecology, fish, and human health; assessed the methods used in Pfiesteria research; and offered suggestions to address data gaps. The panel's expertise covered dinoflagellate ecology; fish pathology and toxicology; laboratory measurement of toxins, epidemiology, and neurology. The panel evaluated peer-reviewed and non-peer-reviewed literature available through June 2000 in a systematic conceptual framework that moved from the source of exposure, through exposure research and dose, to human health effects. Substantial uncertainties remain throughout the conceptual framework the panel used to guide its evaluation. Firm evidence demonstrates that Pfiesteria is toxic to fish, but the specific toxin has not been isolated or characterized. Laboratory and field evidence indicate that the organism has a complex life cycle. The consequences of human exposure to Pfiesteria toxin and the magnitude of the human health problem remain obscure. The patchwork of approaches used in clinical evaluation and surrogate measures of exposure to the toxin are major limitations of this work. To protect public health, the panel suggests that priority be given research that will provide better insight into the effects of Pfiesteria on human health. Key gaps include the identity and mechanism of action of the toxin(s), the incomplete description of effects of exposure in invertebrates, fish, and humans, and the nature and extent of exposures that place people at risk.

Abstract
OBJECTIVE Anecdotal reports have proposed the use of the 5-hydroxytriptamine(4) agonist cisapride as a treatment for female voiding dysfunction on the basis of the known prokinetic actions of the medication. The purpose of our study is to assess the effects of this agent on the normal bladder in vivo. STUDY DESIGN In this randomized, double-blind placebo-controlled trial, patients were randomized to receive either 20 mg cisapride or an identical placebo. They then underwent urodynamic evaluation that included uroflowmetry, multichannel filling cystometry, pressure-flow studies, and a urethral pressure profile. After a washout period of at least 7 days, subjects were then crossed over to the other arm and the tests were repeated. RESULTS Twenty women without significant urinary incontinence agreed to participate. There was a decrease in the maximum cystometric capacity from 556 mL for placebo to 496 mL for cisapride (P <.001). There was no difference in the detrusor pressure at maximum flow, the maximum detrusor pressure, the flow rate, or the percentage of maximum cystometric capacity voided. CONCLUSIONS In healthy women, cisapride caused a significant decrease in the maximum cystometric capacity, which could account for the higher reported rates of urinary frequency and urgency with this medicine. There was no evidence that this prokinetic agent improved voiding function.

Abstract
External feedback can enhance (or depress) the response of a noisy bistable system to monochromatic signals, significantly magnifying its natural stochastic resonance. We compare and contrast a variety of such feedback strategies, using both numerical simulations and analog electronic experiments. These noninvasive control techniques are especially valuable for noisy bistable systems that are difficult or impossible to modify internally.

Abstract
In order to assess impacts associated with disposal of contaminated mud arising from Hong Kong's dredging and reclamation projects, a methodology has been formulated to determine the level of risk posed by consumption of seafood/marine prey species to humans and to the Chinese White Dolphin (Sousa chinensis). This methodology improves on previously used techniques by incorporating risks for organic contaminants, accounting for doses from sources other than seafood, and incorporating additional local knowledge on Sousa chinensis behaviour. It thus represents an advance in risk assessment techniques and a new integration of risk assessment and monitoring in environmental management.

Abstract
The concept of controlling stochastic resonance has been recently introduced [L. Gammaitoni et al., Phys. Rev. Lett. 82, 4574 (1999)] to enhance or suppress the spectral response to threshold-crossing events triggered by a time-periodic signal in background noise. Here, we develop a general theoretical framework, based on a rate equation approach. This generic two-state theory captures the essential features observed in our experiments and numerical simulations.

Abstract
PURPOSE To prospectively study the value of adjuvant chemotherapy in pediatric patients with surgically resected nonrhabdomyosarcomatous soft tissue sarcomas (NRSTS). PATIENTS AND METHODS From June 1986 to May 1992, after complete surgical resection (+/-radiotherapy) of their NRSTS, 81 eligible patients either received adjuvant chemotherapy comprising vincristine, dactinomycin, cyclophosphamide, and doxorubicin or were observed. Only 30 patients accepted randomization, and 15 were assigned to each regimen. Of the remaining 51 patients, 19 elected adjuvant chemotherapy and 32 elected observation. RESULTS Patients were predominantly male, and 69% of all patients were white. The median age at diagnosis was 12.3 years (range, 9.2 to 20.7 years). For the 81 eligible patients, the 5-year overall survival estimate was 84.5% +/- 4.4% and event-free survival was 72.2% +/- 5.4%. Among randomized patients, the 5-year estimated overall survival rate was 93.3% +/- 7%, and the event-free survival rate was 86.7% +/- 9.5% for the observation group, compared with 69.2% +/- 13% and 40.7% +/- 14%, respectively, for those who received chemotherapy. The significantly worse outcome of patients who received adjuvant chemotherapy disappeared when survival was stratified by tumor grade. Among all patients, a grade 3 lesion conferred a significant disadvantage with respect to event-free survival (P =.0001). CONCLUSION The administration of adjuvant chemotherapy according to the schedule and dosages used in our trial did not improve the outcome of children with resected NRSTS. In this study, tumor grade was the most important predictor of clinical outcome in patients with resected NRSTS, and this factor should be incorporated into the stratification of patients in future trials.

Abstract
It was found that the axonal length was inversely related to motor conduction velocity (CV). However, it is not clear that sensory CV is inversely related to axonal length. The nerve lengths of the median sensory fascicles from the C6 and C7 intervertebral foramen to the digital branches of the thumb and middle finger were compared in ten cadavers. Sixty healthy subjects (24 men, 36 women; mean age 35, range 24-54 years) had median sensory CV testing. The median sensory nerve action potentials were obtained antidromically in the thumb and middle finger with wrist and elbow. The CVs across the forearm for the thumb and the middle finger fascicles were then calculated. It was found that the nerve length of C7 was longer than C6 with a difference of 3.6 +/- 0.6 cm. The mean forearm CV for the median sensory axons innervating the middle finger (60.0 +/- 3.9 m/s) was slower than the CV for the median sensory axons innervating the thumb (61.4 +/- 4.1 m/s,p = 0.0012). These results demonstrate that sensory CV is slowed by 3.9 m/s per 10 cm of axon length. This study confirms that the inverse relation of CV and axonal length reported in motor axons also applies to the sensory nerves.

Abstract
PURPOSE To determine if involved field radiation (IF) is equivalent to standard whole bone radiation (SF) in local tumor control; to establish patterns of failure following treatment; and to determine response, event-free survival (EFS), and overall survival rates from multidisciplinary therapy in Ewing's sarcoma. METHODS AND MATERIALS Between 1983 and 1988, 184 children with Ewing's sarcoma were enrolled onto Pediatric Oncology Group 8346 (POG 8346). A total of 178 (97%) met eligibility criteria; 6 had pathology other than Ewing's sarcoma. Induction chemotherapy of cyclophosphamide/doxorubicin (adriamycin )(C/A) x 12 weeks was followed by local treatment either surgery or radiation therapy and C/A, dactinomycin, and vincristine for 50 weeks. Resection was advised for patients with small primary tumors if accomplished without functional loss. Forty patients were randomized to receive SF, whole bone radiation to 39.6 Gy plus a 16.2 Gy boost (total 55.8 Gy) or IF to 55.8 Gy, and the remainder were assigned to IF radiation. RESULTS Of 178 eligible patients, 141 (79%) had localized disease and 37 (21%) had metastases at presentation. Their 5-year EFS was 51% (SE 5%) and 23% (SE 7%) respectively. The response rate to induction chemotherapy was 88% (28% complete, 60% partial), but after radiotherapy the response rate increased to 98%. Thirty-seven of the localized patients underwent resection, of whom 16 (43%) required postoperative radiotherapy; the 5-year EFS of these surgical patients was 80% (SE 7%). The remaining 104 localized patients were eligible for randomization or assignment to receive radiotherapy; the 5-year EFS of these patients was 41% (SE 5%), with no significant difference in EFS between those randomized to SF vs. IF. Site of primary tumor correlated with 5-year EFS: distal extremity 65% (SE 8%), central 63% (SE 10%), proximal extremity 46% (SE 8%), and pelvic-sacral 24% (SE 10%) (p=0.004). Initial tumor size did not correlate significantly with EFS. Patterns of failure among the 141 localized patients revealed 23% of patients experienced a local failure, while 40% had a systemic failure. The 5-year local control rate for the surgical patients +/- postoperative radiotherapy was 88% (SE 6%), while for the patients undergoing radiotherapy alone it was 65% (SE 7%). There was no difference in local control between those randomized to SF vs. IF. The 5-year local control rate for the patients with pelvic-sacral tumors was 44% (SE 15%), significantly worse than the local control rates for those with central tumors 82% (SE 8%), distal extremity 80% (SE 8%), or proximal extremity 69% (SE 9%) (p=0.023). However, quality of radiotherapy correlated with outcome. Patients who had appropriate radiotherapy had a 5-year local control of 80% (SE 7%), while those with minor deviations had 5-year local control of 48% (SE 14%), and those with major deviations had a local control of only 16% (SE 15%) (p=0.005). The local failure was within an irradiated volume in 62% of patients, outside the irradiated volume in 24% of cases, while the precise location could not be determined in the remaining 14%. CONCLUSIONS As most failures in Ewing's sarcoma are systemic, improved EFS requires more effective systemic chemotherapy. Adequate IF radiotherapy requires treatment to appropriate volumes as defined by MRI imaging and full radiation doses. Pretreatment review of radiologic images with a musculoskeletal radiologist to determine appropriate tumor volumes, as well as use of conformal radiotherapy techniques are important for improved outcome.

Abstract
BACKGROUND The objectives of this study were to compare vincristine/actinomycin D/cyclophosphamide/adriamycin (VACA) with VACA/plus imidazole carboxamide (DTIC) (VACAD) therapy in regards to complete/partial response and event free survival rates in children and adolescents with metastatic non-rhabdomyosarcoma soft tissue sarcomas (NRSTS) or previously chemotherapy-naive recurrent NRSTS or locally persistent gross residual tumor after surgery and radiation therapy. PROCEDURES Between 1986 and March 1994, 75 patients entered this randomized study comparing VACA and VACAD, given at 3 week intervals. Sixty-one patients were considered eligible and received chemotherapy and radiation therapy to the primary tumor and areas of metastases. Thirty-six patients had regional unresected (Group III) disease, and 25 had metastatic disease (Group IV) at time of accession. Thirty-six patients received VACA (11 were not randomized), and 25 received VACAD. RESULTS With a median follow-up of greater than 4 years, overall and event-free survival for all eligible patients are 30.6% and 18.4% respectively (S.E: 9.5% and 6.8%). There was insufficient evidence that DTIC offered any advantage to event free survival, but there was evidence for better outcome for patients in Group III disease in comparison to patients with Group IV disease, and for patients with a Grade 1 and 2 histology in comparison to Grade 3 lesions. CONCLUSIONS Combination chemotherapy with VACA and VACAD were insufficient to prevent recurrent or progressive disease in children and adolescents with high stage NRSTS. The use of vincristine/ifosfamide/doxorubicin with cytokine support is under study.

Abstract
The design of a bidirectional free-space optical interconnect system is presented. Vertical-cavity surface-emitting laser (VCSEL) arrays as a coherent light source and VCSEL beam collimation are described. Hologram array design and a way to improve the diffraction efficiency by use of a copying technique utilizing Dupont photopolymers are presented. Scattering from the hologram as a noise source is measured. An optical model for the design of system parameters such as the VCSEL beam diameter, size and apodization of the hologram, and size of the detector is given on the basis of cross-talk analysis of the system. The effect of VCSEL wavelength variation on system design is considered. Aberrations caused by the Fourier lens in the system are calculated, and ways for correction of the aberrations are discussed.

Abstract
Dupont photopolymer as a potential holographic material for an optical interconnect system was studied. The optimized conditions of recording plane-wave holograms with ∼99% effective diffraction efficiency for infrared reconstruction were obtained by testing different Dupont photopolymers and different copying parameters. The scattering ratios of the holograms recorded with Dupont photopolymers HRF600-10, HRF600-20, and HRF600-38 were measured and compared.

Abstract
A thrombotic etiology has been suggested as the cause of idiopathic avascular necrosis of the hip, although the underlying pathophysiological mechanisms are unknown. Transient osteoporosis of the hip has also been suggested to represent bone marrow edema that may be related to ischemia. We evaluated four patients with idiopathic avascular necrosis and one patient with transient osteoporosis of the hip for thrombotic potential placing a special emphasis on the fibrinolytic system. All five patients had identifiable abnormalities of fibrinolysis. Four patients had elevated levels of plasminogen activator inhibitor (PAI-1) and one patient had an inadequate increase in tissue plasminogen activator (tPA) post venous occlusion. Serum triglycerides were increased in three of the patients. These findings suggest an association between decreased fibrinolytic potential and the subsequent development of avascular necrosis and transient osteoporosis of the hip. These patients should have an evaluation of the fibrinolytic system with tPA and PAI-1 levels as well as a lipid profile.

Abstract
In idiopathic thrombocytopenic purpura, a known immune-mediated disorder, intravenous IgG is the treatment of choice. Success and the lack of side effects of intravenous IgG in the treatment of idiopathic thrombocytopenic purpura have encouraged consideration of its use in the treatment of neurologic disorders of presumed autoimmune pathogenesis. In this report, we describe two patients who developed acute renal failure following intravenous IgG treatment. The first patient had chronic inflammatory demyelinating polyneuropathy and was treated with intravenous IgG instead of prednisone because of preexisting diabetes. The second patient had idiopathic thrombocytopenic purpura and received intravenous IgG treatment as part of standard care. The patient with idiopathic thrombocytopenic purpura had unrelated bilateral high-grade renal artery stenosis. Both patients had a creatinine level of 140 mumol/L (1.6 mg/dL) prior to treatment. Renal biopsies performed during acute renal failure in each patient demonstrated marked swelling and vacuolization of the proximal tubular epithelial cytoplasm typical of high-solute-load-induced damage (similar to that associated with the use of mannitol). This report draws attention to the importance of screening for impaired renal function before intravenous IgG therapy is initiated. The patients we describe received standard doses of intravenous IgG at the recommended infusion rate yet developed oliguric renal failure. Awareness of serious side effects and recognition of predisposing factors provide means of avoiding known life-threatening complications of intravenous IgG therapy.

Abstract
Fine needle aspiration specimens from 29 patients with bone and soft tissue neoplasms were analyzed by flow cytometry for DNA index and cell cycle analysis to determine whether such studies were helpful in cytologic diagnosis. Of 15 cases initially cytologically diagnosed as benign, 14 had a DNA index of 1.0, indicating a diploid population. The remaining case diagnosed as cytologically benign had a DNA index of 1.3. Further tissue from this tumor revealed an osteogenic sarcoma. Of the 14 cases initially diagnosed as malignant, 12 were hyperdiploid. Cell cycle analysis showed that malignant tumors had a higher proportion of cells in S phase (15.2% +/- 8.7%) than benign tumors (6.9% +/- 1.6%). Furthermore, high-grade malignancies had a significantly greater number of cells in S phase (18.5% +/- 1.5%) than low-grade tumors (9.9% +/- 6.3%).

Abstract
Twenty-five patients with soft tissue sarcomas were treated with Ir192 implants following wide local excision at our institution between 1982 and 1987. External beam radiotherapy was given in addition to the implant in a majority of patients. The median follow-up in these 25 patients is 36 months (12 to 75 months). Twenty patients have had no evidence of local recurrence following their primary treatment (FFR = 80%). A multivariate analysis using stepwise logistic regression was used to predict failure in 3 years or less. Potential predictors examined included age, sex, tumor location, primary versus recurrent disease, grade, histology, surgical margins, implant only versus implant plus external beam, and a ratio of the volume of tissue which received 65 Gy (TV65) to the tumor volume (TV), that is (TV65/TV). The single variable which was significantly associated with local failure by 3 years was a TV65/TV of less than one. Once this variable was entered into the analysis, no other factor proved statistically significant. Our data suggest that when attempting local control of soft tissue sarcomas with brachytherapy, the volume of tissue receiving 65 Gy (TV65) from both implant and external beam must exceed the volume of the excised lesion (TV). Since the volume of a tumor can be readily determined prior to surgical excision either by CT or MRI scanning, pre-planning of the implant volume could potentially reduce the rate of local failure.

Abstract
The problem addressed was whether a research-based protocol on oral temperature measurement could be developed and used in the practice setting. The first phase of the study proposed to (a) identify research articles related to the subject; (b) evaluate the quality of the research; (c) assess the adequacy of the research base; and (d) select areas for future study. The results indicated that further clinically-based studies are needed before a protocol can be designed and tested in clinical practice.

Abstract
The effect of open mouth breathing, tachypnea, and hyperpnea, either alone or in combination, on sublingual and tympanic membrane temperature in healthy adults was investigated. Seventy-eight subjects maintained randomly assigned breathing patterns for 15 minutes. Temperatures were monitored immediately prior to and for 5 minutes following the breathing protocol. The only statistically significant finding (p less than .01) was a lower sublingual temperature with open mouth breathing. No significant changes in tympanic membrane temperature were seen.

Abstract
The percutaneous absorption and distribution profile of hexamethylene lauramide (hexahydro-1-lauroyl-1H-azepine) were examined using a rat skin-flap model. After a topical dose to the skin flap, the drug concentrations in the vasculature at the site of drug application and in the systemic blood were monitored simultaneously. Hexamethylene lauramide penetrated the skin and reached a steady state in stratum corneum, viable epidermis, dermis, and cutaneous blood in 3 hr. Its concentration in the skin was much higher than that in the blood. Its apparent concentration in the epidermis was 19 times that in the dermis and about 3000 times that in the cutaneous blood. The percutaneous absorption of 14C-hexamethylene lauramide resulted in ascending systemic blood concentrations throughout the experimental period, whereas the cutaneous blood levels remained steady. The topically absorbed hexamethylene lauramide was quantitatively recovered in urine (85%) and feces (13%). The half-lives of urinary and fecal excretion of 14C-hexamethylene lauramide were 17 and 30 hr, respectively. Hexamethylene lauramide, when topically coadministered in an experimental formulation, enhanced the skin penetration of hydrocortisone with increased drug contents in the stratum corneum (2-fold) and with increased hydrocortisone concentrations in the cutaneous blood (3.4-fold) and the systemic blood (3.5-fold). The results indicated that the high concentration and retention of hexamethylene lauramide in stratum corneum and viable epidermis may contribute to its penetration enhancement effect in the skin. A steady state in percutaneous tissues was observed before the drug reached distribution equilibrium systemically. The systemic blood concentration of a topically applied agent therefore may not reflect its percutaneous kinetic processes before a systemic distribution equilibrium is reached.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The ocular and systemic disposition of levobunolol (LBUN), an antiglaucoma agent, was studied in albino rabbits. After topical administration to eyes, LBUN was rapidly adsorbed, with 2.5% of the dose bioavailable to the intraocular tissues as intact drug and 46% to the systemic circulation. On passage across the cornea, approximately 4.7% of a topically applied LBUN dose was biotransformed to dihydrolevobunolol (DHB), and subsequently became bioavailable to intraocular tissues. The major sites of ocular metabolism were the cornea epithelium and the iris-ciliary body. Another 12% of the topical LBUN dose entered the systemic circulation as DHB after presystemic biotransformation. Our study indicated a rapid absorption of LBUN into the aqueous humor after topical dosing. The tpeak was 15 min after dosing and the Cmax was 4 micrograms/mL. Dihydrolevobunolol (DHB) was formed steadily and reached a maximum in the aqueous humor 45 min after dosing. After distribution equilibrium had been reached, the aqueous humor concentrations of both LBUN and DHB declined. Six hours after dosing, the concentration of DHB in the aqueous humor was approximately 10 times higher than that of its parent compound. Because DHB is equivalent to its parent compound in beta-blocking activity, its formation in the rabbit eye may contribute to the pharmacodynamic effects observed after topical doses of LBUN.

Abstract
A woman with autoimmune oophoritis was found to have luteal phase progesterone levels throughout a six-month period of amenorrhea. The common presentation of amenorrhea or metrorrhagia, despite the presence of a corpus luteum, in women with autoimmune oophoritis might result from this chronic progesterone production. A clinical picture consistent with a persistent corpus luteum may be a very early sign of autoimmune oophoritis.
