Abstract
Rosai-Dorfman disease (RDD) is an uncommon histiocytic disorder typically involving lymph nodes and less frequently extranodal tissues. RDD involving the breast is rare and may clinically and radiologically mimic neoplastic and non-neoplastic disorders. We report seven patients with breast RDD, describe their clinicoradiologic and pathologic features, and discuss the differential diagnosis. Patients, ranging from 15 to 74 years of age, presented with unilateral and unifocal (5/7) or bilateral and multifocal (2/7) masses. RDD was either confined to the breast (6/7) or concurrently involved a lymph node (1/7). Masses ranged from 8 to 31 mm, categorized as Breast Imaging-Reporting and Data System (BI-RADS) 4 (6/7) or 5 (1/7). All cases showed similar morphology with many large histiocytes displaying emperipolesis with associated fibrosis and dense lymphoplasmacytic infiltrate. The abnormal histiocytes co-expressed CD68/CD163, S100, OCT2, and Cyclin D1 (7/7), and were negative for CK AE1/AE3 (7/7), CD1a (7/7), and BRAF V600E (6/6). Flow cytometry (n = 3), kappa/lambda in situ hybridization (n = 5), and IgG4/IgG immunohistochemistry (n = 1) did not reveal lymphoma or IgG4-related disease. No mycobacterial or fungal organisms were identified on acid-fast bacillus (AFB) and Grocott methenamine silver (GMS) stains (n = 5). Three patients underwent complete excision and none recurred or progressed to systemic disease during follow-up (88-151 months). In summary, breast RDD should be included in the differential diagnosis of a mass-forming breast lesion. Histopathology with ancillary studies and clinicoradiologic correlation is essential for accurate diagnosis and optimal clinical management. Patients with RDD of the breast have an excellent prognosis after complete excision.

Abstract
Few cases of natural sudden death presenting as an undiagnosed lymphoma have been reported in the literature, especially in adolescents. Herein we provide a report of sudden death caused by undiagnosed classic Hodgkin lymphoma (cHL). We describe an 18-year-old female who collapsed after several weeks of weight loss, decreased appetite, and dyspnea. At autopsy, a bulky mass arising in the mediastinum and neck compressed the esophagus and trachea, surrounded the great vessels, obliterated the pericardial sac, and infiltrated the myocardium. The lungs were collapsed and large pleural effusions were present. The tumor burden, which weighed at least 2710 g in aggregate, was entirely above the diaphragm. Microscopic examination of the masses showed features typical for nodular sclerosis cHL including large bands of sclerosis, numerous Hodgkin/Reed-Sternberg (HRS) cells, and an eosinophil-rich mixed inflammatory cell infiltrate. Immunohistochemical stains showed the HRS cells to be uniformly positive for CD30 and CD15 and negative for CD3, CD20, CD45, and PAX5. This case exemplifies a rare sudden natural death due to previously undiagnosed cHL in a young patient.

Abstract
Abstract
Introduction
There is a myriad of existing terms by which visual capacity is recorded. The lack of a standardised categorisation of observations commonly results in ambiguities. We report the utility of a visual function score (VFS) in patients managed by transsphenoidal surgery.
Method
A VFS (expressed as a percentage) with a maximum score of 20 was calculated for each eye using the Snellen VA (40% weighting: score 0-8) and Humphrey Allergan 30-2 automated visual field (60% weighting: score 0-12).
Results
280 patients (560 eyes) underwent transsphenoidal pituitary adenoma resections with complete pre- and post-operative visual function assessment. Mean age 56 years; 56.4% male. 26.1% were treated by endoscopic technique and 73.9% were treated by microscopic technique. Pre-operative vision was normal in 38.0% eyes. All these had full post-operative vision. In patients with pre-operative visual loss (347 eyes), the mean pre-operative VFS rose from 70.8% to 87.5% post-operatively. 43.8% eyes attained full post-operative vision, 28% improved, and 25.6% remained unchanged. 9 patients (2.6%) had worse immediate post-operative vision.
Conclusions
The VFS is a convenient single measure of visual function that may facilitate local and national audit of transsphenoidal surgery. Studies are planned to correlate this with patient reported visual quality of life measures.

Abstract
Temperature plays a critical role in defining the seismogenic zone, the area of the crust where earthquakes most commonly occur; however, thermal controls on fault ruptures are rarely observed directly. We used a rapidly deployed seismic array to monitor an unusual earthquake cascade in 2018 at Lombok, Indonesia, during which two magnitude 6.9 earthquakes with surprisingly different rupture characteristics nucleated beneath an active arc volcano. The thermal imprint of the volcano on the fault elevated the base of the seismogenic zone beneath the volcanic edifice by 8 km, while also reducing its width. This thermal "squeezing" directly controlled the location, directivity, dynamics, and magnitude of the earthquake cascade. Earthquake segmentation due to thermal structure can occur where strong temperature gradients exist on a fault.

Abstract
OBJECTIVES Given the increased complexity of molecular and cytogenetic testing (MOL-CG), the Society for Hematopathology Education Committee (SH-EC) was interested in determining what the current expectations are for MOL-CG education in hematopathology (HP) fellowship training. METHODS The SH-EC sent a questionnaire to HP fellowship program directors (HP-PDs) covering MOL-CG training curricula, test menus, faculty background, teaching, and sign-out roles. These findings were explored via a panel-based discussion at the 2018 SH-EC meeting for HP-PDs. RESULTS HP fellows are expected to understand basic principles, nomenclature, and indications for and limitations of testing. Interpretation of common assays is within that scope, but not necessarily proficiency in technical troubleshooting of testing or analysis of complex raw data. CONCLUSIONS The consensus was that HP fellows should understand the components of MOL-CG testing necessary to incorporate those results into an accurate, clinically relevant, and integrated HP report.

Abstract
BACKGROUND Liposarcoma is an extremely rare primary bone sarcoma. CASE PRESENTATION We report a case of primary pleomorphic liposarcoma that arose in an 18 year old male in the metaphysis of the left tibia. Plain radiographs showed a partly sclerotic lesion and MR imaging a heterogeneous tumour predominantly isointense on T1- and high-signal on T2-weighted sequences with focal areas of increased T1 signal that suppressed with fat saturation. PET/CT showed marked FDG uptake (SUV = 17.1) in the primary tumour as well as a metastasis in the right distal femur and multiple small pulmonary metastases. Histologically, the tumour was a pleomorphic liposarcoma containing large tumour cells with vacuolated cytoplasm and hyperchromatic pleomorphic nuclei as well as numerous lipoblasts and scattered brown fat-like cells. Tumour cells strongly expressed FABP4/aP2, a marker of adipocyte differentiation, and UCP1, a marker of brown fat, but not S100. The case was treated with neoadjuvant MAP chemotherapy, resulting in extensive (> 95%) necrosis in the primary tumour and almost complete resolution of the femoral and pulmonary metastases. CONCLUSIONS Pleomorphic liposarcoma can present as a sclerotic primary malignant bone tumour; markers of adipose differentiation are useful in histological diagnosis and neoadjuvant MAP chemotherapy results in significant tumor necrosis.

Abstract
OBJECTIVES To assess the prevalence of impinged spinous processes in asymptomatic dogs. METHODS One hundred and ninety lateral thoracic radiographs of asymptomatic dogs radiographed for reasons other than spinal pain, were retrospectively reviewed by two board-certified radiologists. Images were assessed for impinged spinous processes and graded for narrowing, sclerosis or remodelling of the spinous processes. RESULTS The prevalence of impinged spinous processes in unaffected dogs was 33·2%. Seventy-five of 79 (95%) lesions were located between T8 and T11. Impingement of the spinous processes was more common in older dogs and larger dogs displayed more frequent and more severe impingement of the spinous processes compared with smaller breeds. CLINICAL SIGNIFICANCE Spinous process impingement is common in animals with no history of spinal pain, indicating that this radiographic finding should be interpreted with caution.

Abstract
AIMS Childhood cancer survivors treated with haematopoietic stem cell transplantation (HSCT) and total body irradiation are at an increased risk of developing diabetes early in life due to insulin resistance and β-cell dysfunction, but the optimal screening method is unknown. The National Institute for Health and Care Excellence guidelines for community diabetes screening recommend using fasting glucose ≥ 7 mmol/l and/or HbA1c ≥ 48 mmol/mol (6.5%) for diagnosis and, fasting glucose 5.5-6.9 mmol/l or HbA1c 42-47 mmol/mol (6-6.5%) to indicate high risk. This study aimed to evaluate the sensitivities of fasting glucose and HbA1c in the diagnosis of diabetes and impaired glucose tolerance in childhood HSCT survivors. METHOD The patients were 35 (male = 19) HSCT survivors from a single UK centre under follow-up from 2006 to 2013. Patients had a median age (range) of 19.2 (13.1-26.2) years and had been treated for acute lymphoblastic (n = 31) or myeloid (n = 4) leukaemia when aged 7.8 (2.4-16.7) years. The outcome measures were oral glucose tolerance test (OGTT), fasting glucose and HbA1c . RESULTS OGTT identified 6 patients with diabetes (120-min glucose ≥ 11.1 mmol/l), 12 with impaired glucose tolerance (120-min glucose 7.8-11.0 mmol/l) and 2 with impaired fasting glucose (≥ 7 mmol/l). Fasting glucose ≥ 7 mmol/l or HbA1c ≥ 48 mmol/mol identified two of the six patients with diabetes diagnosed on OGTT. Fasting glucose ≥ 5.5 mmol/l and HbA1c ≥ 42 mmol/mol identified three and two patients, respectively, with diabetes. Only 1 of 12 patients with impaired glucose tolerance had a fasting glucose ≥ 5.5 mmol/l and none had HbA1c ≥ 42 mmol/mol (≥ 6%). CONCLUSIONS The fasting glucose and HbA1c cut-offs used in UK population screening only identified one-third of HSCT survivors with diabetes and do not identify those at risk. Diabetes screening in HSCT survivors requires standard OGTTs.

Abstract
Historically, American Indian/Alaska Native (AI/AN) populations have suffered excess morbidity and mortality from influenza. We investigated the risk factors for death from 2009 pandemic influenza A(H1N1) in persons residing in five states with substantial AI/AN populations. We conducted a case-control investigation using pandemic influenza fatalities from 2009 in Alaska, Arizona, New Mexico, Oklahoma and Wyoming. Controls were outpatients with influenza. We reviewed medical records and interviewed case proxies and controls. We used multiple imputation to predict missing data and multivariable conditional logistic regression to determine risk factors. We included 145 fatal cases and 236 controls; 22% of cases were AI/AN. Risk factors (P 45 years vs. <18 years], pre-existing medical conditions (mOR 7·1), smoking (mOR 3·0), delayed receipt of antivirals (mOR 6·5), and barriers to healthcare access (mOR 5·3). AI/AN race was not significantly associated with death. The increased influenza mortality in AI/AN individuals was due to factors other than racial status. Prevention of influenza deaths should focus on modifiable factors (smoking, early antiviral use, access to care) and identifying high-risk persons for immunization and prompt medical attention.

Abstract
Salivary gland myoepithelial carcinoma (MC) or malignant myoepithelioma is a rare entity. MC usually presents as a slow-growing painless mass arising in the parotid gland, but may involve other salivary glands. This tumour may be particularly locally aggressive, but its clinical and biological features are not yet fully understood. MC may arise from pre-existing benign lesions, such as pleomorphic adenomas or benign myoepitheliomas, or may arise de novo. It usually affects patients over 50 years old, with no gender preference. Because it is often asymptomatic, the presentation and diagnosis can be delayed by months, even years. The current WHO classification considers MC to be an intermediate- to high-grade malignancy. Other published data suggest it is likely to be a high-grade neoplasm, consistent with its aggressive behaviour. Its epidemiology, histopathological features, immunohistochemical profile, clinical behaviour and optimal management are not well understood. Following review of the current literature we aim to address these.

Abstract
Exposure to an immune challenge during peripuberty/adolescence, but not in adulthood, can cause enduring alterations in reproductive and non-reproductive behaviors. This suggests that the peripubertal/adolescent brain might respond differently to a stressor, like an immune challenge, than the adult brain. The goal of this study was to examine whether there are age and sex differences in the acute response to an immune challenge. To examine this research question, we investigated c-Fos expression in various brain regions. Corticosterone (CORT) concentration in the serum was quantified to examine hypothalamic-pituitary-adrenal axis (HPA-axis) responsiveness. Results showed that lipopolysaccharide (LPS; a bacterial endotoxin) treatment, induced a significant increase in the number of c-Fos immunoreactive cells in adult male and female mice compared to their saline controls. However, in peripubertal/adolescent mice, LPS treatment failed to increase the number of c-Fos immunoreactive cells in both male and female mice compared to their saline controls. LPS treatment also significantly increased serum CORT concentration in all mice regardless of sex and age. However, adult female mice treated with LPS showed significantly greater serum CORT concentration compared to adult and peripubertal/adolescent males and peripubertal/adolescent females treated with LPS. These findings support our hypothesis and suggest that there are important age and sex differences in acute immune response, which may allude to mechanisms for the enduring behavioral alterations, observed previously in mice exposed to an immune challenge during puberty but not in adulthood.

Abstract
9014 Background: MGd, a radiosensitizer that selectively accumulates in tumors, generates reactive oxygen species intracellularly. In preclinical experiments, MGd enhances RT-induced apoptosis. Methods: A multi-institutional Phase I dose escalation and pharmacokinetic (PK) study was performed in children with newly diagnosed BSG to determine the maximum tolerated dose (MTD) and dose-limiting toxicities (DLT) of MGd administered i.v. 2 to 5 hours prior to involved field radiotherapy (RT) (1.8 Gy/day, total 54 Gy). Cohort 1 received MGd, 1.7 mg/kg/dose M-F × 3 wks and cohort 2 received the same dose M, W and F × 6 wks. The 6 subsequent cohorts of 3 to 6 pts received MGd M-F × 6 weeks at doses of 1.9, 3.4, 4.4, 5.5, 7.1 and 9.2 mg/kg/dose. Serum for PK analysis, and MRI scans (MGd is detectable by MR), were obtained for analysis of drug accumulation and responses. Results: 44 pts (42 fully evaluable for toxicity) with a median age of 6 years (range 2–20) were enrolled. At the 9.2 mg/kg/dose, 2/2 pts experienced DLT. During subsequent expansion of the 7.1 and 5.5 mg/kg/dose cohorts, DLTs, including transaminitis, hypertension and urticaria, were observed in 2/5 and 2/6 pts. At the MTD of 4.4 mg/kg/dose, 1/6 pts had reversible grade 3 serum transaminase elevations. PK analysis showed biphasic elimination with a terminal t 1/2 of 6.4 h. At the MTD, serum MGd concentrations were >250 ng/ml for 24 h. Serum clearance and steady-state volume of distribution were 0.0243 L/h/kg and 0.162 L/kg. MRI for intra-tumoral MGd distribution is ongoing. One patient had a CR and 4 had a PR. The estimated median survival is 10.3 months (95% confidence interval: 8.1 months-11.5 months). Conclusions: The recommended phase II dose of MGd for children with BSG is 4.4 mg/kg/d administered M-F × 6 weeks with involved field RT. A COG phase II trial is planned. [Table: see text]

Abstract
The optimal monoclonal antibody to examine steroid hormone receptor status of primary breast carcinoma has yet to be defined. Estrogen receptor status was evaluated in 592 cases using routinely prepared paraffin-embedded tissue samples from primary breast carcinomas with the 1D5 (DAKO, Carpinteria, CA) and 6F11 (Novocastra, Newcastle upon Tyne, England) monoclonal antibodies. The stains were compared, assessing the percentage of positive cells stained and their intensity. They also were examined for nonspecific cytoplasmic staining and fixation artifact. In addition, a cost analysis for their production was performed. Overall, 1D5 and 6F11 showed a 97.5% concordance rate. 6F11 stained a significantly higher percentage of cells (P < .0001), more intensely (P < .0001), with less nonspecific cytoplasmic staining (P < .0001). There was no significant difference in fixation artifact between the 2 clones. The cost of antibody used for preparing a 1D5-stained slide was 86% more than for preparing a 6F11-stained slide (dollars 14.27 vs dollars 7.67).

Abstract
A retrospective study was undertaken to determine the prevalence of different diseases in cats referred for investigation of chronic nasal disease, to identify historical, clinical and diagnostic features which may assist in making a diagnosis, and to provide information pertaining to outcome in these cats. Diagnoses included neoplasia (30 cases), chronic rhinitis (27), foreign body (8), nasopharyngeal stenosis (5), Actinomyces infection (2), nasal polyps (2), stenotic nares (2), and rhinitis subsequent to trauma (1). The most common neoplasia was lymphosarcoma (21 cases), with a median survival of 98 days for cats treated with multiagent chemotherapy. Cats with neoplasia were older on average than the other cats, and were more likely to be dyspnoeic and have a haemorrhagic and/or unilateral nasal discharge than cats with chronic rhinitis. Cats with neoplasia were more likely to have radiographic evidence of nasal turbinate destruction, septal changes, or severe increases in soft tissue density than cats with chronic rhinitis. It was unusual for cats with diseases other than neoplasia to be euthanased as a result of their nasal disease.

Abstract
BACKGROUND Creutzfeldt-Jakob disease (CJD) in humans and chronic wasting disease (CWD) in deer and elk occur in the United States. Recent reports of 3 unusually young patients with CJD who regularly consumed deer or elk meat created concern about the possible zoonotic transmission of CWD. OBJECTIVE To examine the possible transmission of CWD to humans. PATIENTS Three unusually young patients (aged 28, 28, and 30 years) with CJD in the United States during 1997-2000. METHODS We reviewed medical records and interviewed family members and state wildlife and agriculture officials. Brain tissue samples were tested using histopathologic, immunohistochemical, immunoblot, or prion protein gene analyses. MAIN OUTCOME MEASURES Presence or absence of established CJD risk factors, deer and elk hunting in CWD-endemic areas, and comparison of the evidence for the 3 patients with that of a zoonotic link between new variant CJD and bovine spongiform encephalopathy. RESULTS None of the patients had established CJD risk factors or a history of travel to Europe. Two patients hunted game animals and 1 was a daughter of a hunter. Unlike patients with new variant CJD, the 3 patients did not have a unique neuropathologic manifestation, clinicopathologic homogeneity, uniformity in the codon 129 of the prion protein gene, or prion characteristics different from those of classic variants. CONCLUSIONS Although the occurrence of 3 unusually young patients with CJD who consumed venison suggested a possible relationship with CWD, our follow-up investigation found no strong evidence for a causal link. Ongoing CJD surveillance remains important for continuing to assess the risk, if any, of CWD transmission to humans.

Abstract
The evaluation and triage of patients with suspected myocardial ischemia in the emergency department remains challenging and costly. Previous studies of cardiac troponins have focused predominantly on patients with chest pain and have not randomized patients to different diagnostic strategies. Eight hundred fifty-six patients with suspected myocardial ischemia were prospectively randomized to receive a standard evaluation, including serial electrocardiographic and creatine phosphokinase-MB determinations (controls) or a standard evaluation with the addition of serial troponin T determinations (troponin group). The primary end points were length of stay and hospital charges. Significant reductions in length of hospital stay were seen in troponin T patients both with (3.6 vs 4.7 days; p = 0.01) and without (1.2 vs 1.6 days; p = 0.03) acute coronary syndromes compared with controls. Total hospital charges were reduced in a similar fashion in troponin patients with and without acute coronary syndromes ($15,004 vs $19,202; p = 0.01, and $4,487 vs $6,187; p = 0.17, respectively) compared with controls. Troponin patients without acute coronary syndromes had fewer hospital admissions (25% vs 31%; p = 0.04), whereas troponin patients with acute coronary syndromes had shorter telemetry and coronary care unit lengths of stay (3.5 vs 4.5 days; p = 0.03) compared with controls. Thus, utilization of troponin T in a broad spectrum of emergency department patients with suspected myocardial ischemia improves hospital resource utilization and reduces costs.

Abstract
Peripheral blood-derived monocytes spontaneously undergo apoptosis mediated by Fas-Fas ligand (FasL) interactions. Activation of monocytes by LPS or TNF-alpha prevents spontaneous monocyte apoptosis through an unknown mechanism. Here, we demonstrate that LPS and TNF-alpha up-regulate Flip and suppress spontaneous Fas-FasL mediated monocyte apoptosis and caspase 8 and 3 activation. Flip was responsible for this protection, since inhibition of Flip by antisense oligonucleotides in the presence of LPS or TNF-alpha restored monocyte sensitivity to spontaneous apoptosis. We also investigated whether the PI3K pathway contributes to the suppression of spontaneous monocyte apoptosis mediated by LPS and TNF-alpha. Monocytes treated with a reversible PI3K inhibitor (LY294002) displayed enhanced apoptosis, while LPS and TNF-alpha partially protected against apoptosis mediated by LY294002. However, direct suppression of Fas-FasL interactions by addition of neutralizing anti-FasL antibody did not further suppress LY294002-induced apoptosis in the presence of LPS or TNF-alpha. Collectively, these data demonstrate that LPS or TNF-alpha protect monocytes from death receptor-mediated apoptosis through the up-regulation of Flip, but not apoptosis initiated by inhibition of the PI3K pathway.

Abstract
Elliptic flow from nuclear collisions is a hadronic observable sensitive to the early stages of system evolution. We report first results on elliptic flow of charged particles at midrapidity in Au+Au collisions at square root(S)NN = 130 GeV using the STAR Time Projection Chamber at the Relativistic Heavy Ion Collider. The elliptic flow signal, v2, averaged over transverse momentum, reaches values of about 6% for relatively peripheral collisions and decreases for the more central collisions. This can be interpreted as the observation of a higher degree of thermalization than at lower collision energies. Pseudorapidity and transverse momentum dependence of elliptic flow are also presented.

Abstract
The purpose of this study was to assess strategies to improve telephone contact with adult patients discharged from the emergency department (ED). The basic procedure was a prospective, randomized, interventional trial of a convenience sample of patients 18 years or older being discharged from the ED. Patients were excluded if they had altered mental status or were unable to communicate with the College Research Associates (RAs). RAs asked intervention subjects a set of scripted questions confirming patients' telephone numbers and times for a follow-up call. Control subjects received routine discharge instructions from the ED staff. Subjects were called back within 4 days of ED discharge. Eighty-seven control subjects and 76 intervention subjects were enrolled. There were no significant demographic differences between the 2 groups. Forty-seven (54%) control subjects were contacted versus 58 (77%) in the intervention group (P <.003; Chi-square test). A simple patient interview conducted immediately before discharge confirming the patient's telephone number and setting a time for a follow-up call significantly improved patient follow-up contact rates.

Abstract
The thermoelectric power (TEP) of single-walled carbon nanotubes (SWNTs) is extremely sensitive to gas exposure history. Samples exposed to air or oxygen have an always positive TEP, suggestive of holelike carriers. However, at fixed temperature the TEP crosses zero and becomes progressively more negative as the SWNTs are stripped of oxygen. The time constant for oxygen adsorption/desorption is strongly temperature dependent and ranges from seconds to many days, leading to apparently "variable" TEP for a given sample at a given temperature. The saturated TEP can be accounted for within a model of strong oxygen doping of the semiconducting nanotubes.
