Abstract
Acute neonatal osteomyelitis is a challenging disease and its diagnostic is important to avoid comorbidities. Staphylococcus aureus is the most often involved germ. The diagnostic challenge lies in its pauci-symptomatology in the premature infant in contrast to a more obvious clinical presentation in the term infant or child. The risk factors inherent to prematurity are invasive monitoring, repeated blood sampling, prolonged central catheterization, immature immune response and length of hospital stay. We report the case of an osteomyelitis secondary to staphylococcal sepsis in a preterm infant born at 25 weeks and 3 days of gestational age. The diagnosis was made incidentally on an abdominal x-ray. The low parental compliance for the child's follow-up does not allow us to affirm a future without sequelae even if the elements at our disposal at 8 months suggest a favorable outcome. Acute neonatal osteomyelitis remains a difficult but crucial diagnosis for the future development of the child.

Abstract
Aim To investigate if the massive blood loss protocol ‘Code Red’ at a specialist cardiothoracic hospital was activated according to local and national guidelines by a closed loop audit. Methods Electronic and paper patient care systems were searched in 2015 and 2018 to access records for the ‘Code Red’ activations. Activation of the massive blood loss protocol was compared against the national standards set by The British Committee for Standards in Haematology. The percentage of cases meeting each of the ten standards in the specialist cardiac unit’s Protocol for the Management of Massive Blood Loss in Adults (adapted from the national standards) were evaluated. Results ‘Code Red’ protocol was activated on 18 occasions in 2015 and nine occasions in 2018, representing just 0.83 and 0.26% of emergency surgeries, respectively. Between 2015 and 2018, there was a 6% increase of ‘Code Red’ cases being appropriately activated, a 26% increase in the prompt notification of the haematology department upon activation, alongside a 30% increase in the timely delivery of blood products, and a 25% decrease in the average amount of blood transferred prior to ‘Code Red’ activation. Conclusion There has been an improvement in the standards of care and management of massive blood loss this specialist cardiac centre despite the target timeframe being reduced from 30 to 15min between 2015 and 2018. Preparation for and anticipation of massive blood loss has likely decreased the number of incidences requiring ‘Code Red’ activation, permitting delivery of safe patient care.

Abstract
INTRODUCTION In Eswatini in Southern Africa, rural populations experience unnecessary snakebite-inflicted injuries and deaths. Children are at the highest risk because of their small size and curious nature. This qualitative study explores the current knowledge and attitudes about snakebite, and the perceptions of a musical intervention, titled Iculo ngenyoka ('Snake song' in Zulu), as an educational tool aimed to raise awareness about snakes in the Lubombo region, Eswatini. METHODS Semi-structured interviews with community members (n=56), parents/guardians/key informant (n=11) and children aged 7-17 years (n=45) were conducted between May and June 2018. Participants were selected from four communities within the Lubombo region. Data were analyzed using a framework analysis approach. RESULTS The current sources of snake education evolved from information learned in the homesteads, schools, and through personal experiences. The majority of interviewees perceived music as a culturally appropriate, engaging and memorable method to learn about snakes. Iculo ngenyoka was perceived as an effective tool to raise awareness about snakes in the community. CONCLUSION This study is the first to explore the importance of musical interventions in educating vulnerable communities about snakes. The Iculo ngenyoka song offers a portable medium for communicating messages about snakebite prevention, affirming the value of snakebite awareness and promoting cooperative efforts to address the burden of snakebite envenoming in the region. The results emphasize the demand for education and the potential use of Iculo ngenyoka and similar musical tools to raise awareness about snakebite in Eswatini. Re-translation and other customizations of structured musical education tools for children could be applied broadly if shown to be effective.

Abstract
PURPOSE The purpose of this study was to compare ventricular vascular coupling ratio (VVCR) between patients with repaired standard tetralogy of Fallot (TOF) and those with repaired TOF-pulmonary atresia (TOF-PA) using cardiovascular magnetic resonance (CMR). MATERIALS AND METHODS Patients with repaired TOF aged>6 years were prospectively enrolled for same day CMR, echocardiography, and exercise stress test following a standardized protocol. Sanz's method was used to calculate VVCR as right ventricle (RV) end-systolic volume/pulmonary artery stroke volume. Regression analysis was used to examine associations with exercise test parameters, New York Heart Association (NYHA) class, RV size and biventricular systolic function. RESULTS A total of 248 subjects were included; of these 222 had repaired TOF (group I, 129 males; mean age, 15.9±4.7 [SD] years [range: 8-29 years]) and 26 had repaired TOF-PA (group II, 14 males; mean age, 17.0±6.3 [SD] years [range: 8-29 years]). Mean VVCR for all subjects was 1.54±0.64 [SD] (range: 0.43-3.80). Mean VVCR was significantly greater in the TOF-PA group (1.81±0.75 [SD]; range: 0.78-3.20) than in the standard TOF group (1.51±0.72 [SD]; range: 0.43-3.80) (P=0.03). VVCR was greater in the 68 NYHA class II subjects (1.79±0.66 [SD]; range: 0.75-3.26) compared to the 179 NYHA class I subjects (1.46±0.61 [SD]; range: 0.43-3.80) (P<0.001). CONCLUSION Non-invasive determination of VVCR using CMR is feasible in children and adolescents. VVCR showed association with NYHA class, and was worse in subjects with repaired TOF-PA compared to those with repaired standard TOF. VVCR shows promise as an indicator of pulmonary artery compliance and cardiovascular performance in this cohort.

Abstract
Non-specific Interstitial Pneumonia (NSIP) is an anatomo-clinical entity within the group of Diffuse Infiltrative Pulmonary Diseases (DPID). It is very rarely found in pediatrics. Main symptoms are dry cough and dyspnea. Bronchoalveolar lavage and biology are non specific. The thoracic CT scan suspects the diagnosis, but histological examination of a lung biopsy remains the reference examination and makes the diagnosis highly probable according to the ATS / ERS criteria. An autoimmune assessment should be performed because NSIPs are often associated with connective tissue disease or may even be the first sign of connectivitive tissues diseases. The treatment of the acute phase is mainly based on the administration of corticosteroids and the prognosis is generally good. In this article, we describe the management of NSIP, based on a pediatric clinical case.

Abstract
The cost-effectiveness of the standard of care for snakebite treatment, antivenom, and supportive care has been established in various settings. In this study, based on data from South Indian private health-care providers, we address an additional question: "For what cost and effectiveness values would adding adjunct-based treatment strategies to the standard of care for venomous snakebites be cost-effective?" We modeled the cost and performance of potential interventions (e.g., pharmacologic or preventive) used adjunctively with antivenom and supportive care for the treatment of snakebite. Because these potential interventions are theoretical, we used a threshold cost-effectiveness approach to explore this forward-looking concept. We examined economic parameters at which these interventions could be cost-effective or even cost saving. A threshold analysis was used to examine the addition of new interventions to the standard of care. Incremental cost-effectiveness ratios were used to compare treatment strategies. One-way, scenario, and probabilistic sensitivity analyses were conducted to analyze parameter uncertainty and define cost and effectiveness thresholds. Our results suggest that even a 3% reduction in severe cases due to an adjunct strategy is likely to reduce the cost of overall treatment and have the greatest impact on cost-effectiveness. In this model, for example, an investment of $10 of intervention that reduces the incidence of severe cases by 3%, even without changing antivenom usage patterns, creates cost savings of $75 per individual. These findings illustrate the striking degree to which an adjunct intervention could improve patient outcomes and be cost-effective or even cost saving.

Abstract
Developmental ethanol exposure is a well-known cause of lifelong cognitive deficits, behavioral hyperactivity, emotional dysregulation, and more. In healthy adults, sleep is thought to have a critical involvement in each of these processes. Our previous work has demonstrated that some aspects of cognitive impairment in adult mice exposed at postnatal day 7 (P7) to ethanol (EtOH) correlate with slow-wave sleep (SWS) fragmentation (Wilson et al., 2016). We and others have also previously demonstrated that co-treatment with LiCl on the day of EtOH exposure prevents many of the anatomical and physiological impairments observed in adults. Here we explored cognitive function, diurnal rhythms (activity, temperature), SWS, and parvalbumin (PV) and perineuronal net (PNN)-positive cell densities in adult mice that had received a single day of EtOH exposure on P7 and saline-treated littermate controls. Half of the animals also received a LiCl injection on P7. The results suggest that developmental EtOH resulted in adult behavioral hyperactivity, cognitive impairment, and reduced SWS compared to saline controls. Both of these effects were reduced by LiCl treatment on the day of EtOH exposure. Finally, developmental EtOH resulted in decreased PV/PNN-expressing cells in retrosplenial (RS) cortex and dorsal CA3 hippocampus at P90. As with sleep and behavioral activity, LiCl treatment reduced this decrease in PV expression. Together, these results further clarify the long-lasting effects of developmental EtOH on adult behavior, physiology, and anatomy. Furthermore, they demonstrate the neuroprotective effects of LiCl co-treatment on this wide range of developmental EtOH's long-lasting consequences.

Abstract
Hereditary hemorrhagic telangiectasia is a constitutional vascular dysplasia characterized by chronic epistaxis, mucocutaneous and visceral telangiectasias and arteriovenous malformations. Apart from family screenings, the disease is rarely diagnosed during the pediatric age given the late advent of typical clinical symptoms. Nevertheless, arteriovenous malformations are sometimes already present at a young age with significant morbidity risk. Therefore, it is important to establish an early diagnosis. We describe two pediatric cases of hereditary hemorrhagic telangiectasia and pulmonary arteriovenous malformations with divergent clinical presentation.

Abstract
Snakebite remains a neglected medical problem of the developing world with up to 125,000 deaths each year despite more than a century of calls to improve snakebite prevention and care. An estimated 75% of fatalities from snakebite occur outside the hospital setting. Because phospholipase A2 (PLA2) activity is an important component of venom toxicity, we sought candidate PLA2 inhibitors by directly testing drugs. Surprisingly, varespladib and its orally bioavailable prodrug, methyl-varespladib showed high-level secretory PLA2 (sPLA2) inhibition at nanomolar and picomolar concentrations against 28 medically important snake venoms from six continents. In vivo proof-of-concept studies with varespladib had striking survival benefit against lethal doses of Micrurus fulvius and Vipera berus venom, and suppressed venom-induced sPLA2 activity in rats challenged with 100% lethal doses of M. fulvius venom. Rapid development and deployment of a broad-spectrum PLA2 inhibitor alone or in combination with other small molecule inhibitors of snake toxins (e.g., metalloproteases) could fill the critical therapeutic gap spanning pre-referral and hospital setting. Lower barriers for clinical testing of safety tested, repurposed small molecule therapeutics are a potentially economical and effective path forward to fill the pre-referral gap in the setting of snakebite.

Abstract
BACKGROUND The natural evolution of C1q nephropathy (C1qNP) during immunosuppressive treatment is relatively little studied or understood. CASE PRESENTATION A 30 year-old Caucasian female was referred to us for further management of biopsy-proven C1qNP and severe nephrotic syndrome. Serologic work-up remained negative, including complement C3 and C4 levels and repeated testing for antinuclear antibodies. A renal biopsy revealed minimal change nephropathy vs. focal sclerosis on light microscopy and C1qNP on immunopathology. She has failed trials of high-dose oral prednisone, mycophenolate mofetil 1,500 mg twice a day and a subsequent regimen of monthly IV cyclophosphamide 750 mg × 9 cycles. She also received the maximum tolerated angiotensin-converting enzyme inhibitor and spironolactone therapy. Random urine protein-to-creatinine (UPC) ratio predicted proteinuria in the range between 5-35 gm/day, while serum creatinine rose progressively from 1.0 mg/dL to 1.4 mg/dL (to convert to μmol/L, multiply by 88.4). A decision was made to repeat renal biopsy to reassess the underlying histology. The biopsy revealed focal sclerosis but no C1q deposition. CONCLUSIONS Our case illustrates at least two points: first, an established pathologic diagnosis does not obviate the need for repeated renal biopsy later on, should diagnostic uncertainty persist. Second, histological diagnoses may evolve over time, especially in a patient receiving active and powerful immune-modulating treatment. In our case, the clinical nephrosis did not change with immunosuppressive therapy while C1q deposition ceased, making this latter entity likely the immunologically mediated process.

Abstract
BACKGROUND Lymphocytic gastritis (LG), characterized by marked intra-epithelial lymphocytosis in the gastric mucosa, has been frequently associated with both celiac disease (CD) and H. pylori gastritis. The aim of this study was to review and correlate the morphology of LG with the presence of CD and H. pylori. MATERIALS AND METHODS Gastric biopsies diagnosed with LG from 1/1/2006 to 8/1/2013 at our institution and corresponding small bowel biopsies, when available, were reviewed for verification of the diagnosis and to assess for the presence of H. pylori and CD. Immunohistochemical (IHC) staining for H. pylori was performed on all gastric biopsies. Demographic, clinical, and laboratory data were obtained from the medical record. RESULTS Fifty-four of the 56 cases that met inclusion criteria demonstrated significant intra-epithelial lymphocytosis as the predominant histologic abnormality; however, none were associated with H. pylori infection by IHC staining. Two cases that also showed a prominent intra-epithelial and lamina propria neutrophilic infiltrate were both positive for H. pylori and were excluded from further study. Of the 36 small bowel biopsies available, 19 (53%) showed changes in CD. CONCLUSIONS LG is not a distinct clinicopathologic entity, but a morphologic pattern of gastric injury that can be secondary to a variety of underlying etiologies. When restricted to cases with lymphocytosis alone, LG is strongly associated with CD and not with active H. pylori infection. However, cases that also show significant neutrophilic infiltrate should be regarded as "active chronic gastritis" and are often associated with H. pylori infection. A morphologic diagnosis of LG should prompt clinical and serologic workup to exclude underlying CD.

Abstract
Collagenous sprue (CS) is a pattern of small-bowel injury characterized histologically by marked villous blunting, intraepithelial lymphocytes, and thickened sub-epithelial collagen table. Clinically, patients present with diarrhea, abdominal pain, malabsorption, and weight loss. Gluten intolerance is the most common cause of villous blunting in the duodenum; however, in a recent case series by the Mayo Clinic, it has been reported that olmesartan can have a similar effect. In this case report, a 62-year-old female with a history of hypothyroidism and hypertension managed for several years with olmesartan presented with abdominal pain, weight loss, and nausea. Despite compliance to a gluten-free diet, the patient’s symptoms worsened, losing 20 pounds in 3 wk. Endoscopy showed thickening, scalloping, and mosaiform changes of the duodenal mucosa. The biopsy showed CS characterized by complete villous atrophy, lymphocytosis, and thickened sub-epithelial collagen table. After 2 mo cessation of olmesartan, the patient’s symptoms improved, and follow-up endoscopy was normal with complete villous regeneration. These findings suggest that olmesartan was a contributing factor in the etiology of this patient’s CS. Clinicians should be aware of the possibility of drug-induced CS and potential reversibility after discontinuation of medication.

Abstract
Surveillance of colorectal cancer is currently based on dosage of tumoral markers, colonoscopy and multidetector row computed tomography. However, pelvic magnetic resonance imaging (MRI) and PET-CT are two second-line useful imaging modalities to assess colorectal cancer local recurrence (LR). The anatomical information derived from MRI combined to the functional information provided by diffusion-weighted imaging currently remain of value. Pelvic MRI is accurate not only for detection of pelvic colorectal recurrence but also for the prediction of absence of tumoral invasion in pelvic structures, and it may thus provide a preoperative road map of the recurrence to allow for appropriate surgical planning. As always, correlation of imaging and clinical findings in the multidisciplinary forum is paramount. MRI can also be used to follow-up LR treated with radiofrequency ablation. The aim of this review is to discuss clinical practice and application of MRI in the assessment or pelvic recurrence from colorectal cancer.

Abstract
OBJECTIVES To calculate the incidence of nondiagnostic (ND) colorectal (CR) polyp cases in which deeper tissue sectioning rendered new diagnostic information--particularly adenomas--in 2 laboratories staffed by the same pathologists. METHODS After initial diagnosis, 100 ND CR polyps from each laboratory were reexamined with 3 deeper levels to establish rates of diagnostic conversion based on biopsy specimen location and original observation(s). RESULTS Deeper sectioning rendered new diagnostic information in 43 (21.5%) of 200 biopsy specimens and specifically adenomas in 16 (8.0%) of 200 biopsy specimens. CONCLUSIONS These results support routine ordering of deeper levels on ND CR polyps to improve adenoma detection rates, especially those cases without any histologic abnormality. If another biopsy in the same case already is adenomatous, examination of deeper levels may not be necessary, as it may not have any significant effect on the clinical management of the patient.

Abstract
Fibrosing mediastinitis is a rare condition characterized by an excessive growth of dense fibrous tissue within the mediastinum. The etiology of the disease is most often a fungal infection and may in some cases be idiopathic. We present the case of a patient with chronic obstructive pulmonary disease (COPD) suffering from fibrosing mediastinitis of undetermined origin and in whom the diagnosis was established by histopathological analysis after mediastinoscopy.

Abstract
INTRODUCTION Magnetic Resonance enterography (MRE) is an imaging modality avoiding ionizing radiation and the discomfort associated with enteroclysis. The results of MRE at diagnosis in the patients of the Belgian pediatric Crohn registry (Belcro) are compared to endoscopical and histological results. METHODS Results of MRE, endoscopy and histology were obtained from the medical charts and assigned to one of the following segments: jejunum, ileum, ascending colon, transverse colon, descending colon or rectosigmoid. MRE images were reviewed in a blinded way by 4 radiologists with specific interest in pediatric MRE. RESULTS From the Belcro registry, twenty-two patients underwent a MRE during their work-up for Crohn disease. The results of endoscopy, histology and MRE were concordant (either all negative or positive) in the ileum in 16/18 patients and in the rectosigmoid, descending colon, transverse colon and ascending colon in resp 9, 8, 8 and 8/22 patients. In the non-concordant cases (MRE colon negative but endoscopy and/or histology positive), MRE could not reflect the subtle endoscopic or histologic lesions such as erosions that were described.In 4 cases where ileocaecal valve intubation was impossible ileal MRE findings were abnormal. MRE detected ileal stenosis, jejunal lesions and fistula in resp 4/22, 3/22 en 2/22 patients. The 100% and 75% interobserver agreement was resp 50-82% and 773-100% according to the different intestinal segments. CONCLUSIONS MRE is a promising imaging modality avoiding radiation in Crohn disease. It should probably become the technique of first choice for the evaluation of extensive small bowel disease in children with Crohn disease.

Abstract
An outbreak of verotoxin-producing Escherichia coli O157 (VTEC O157) infections linked to an open farm occurred in eastern England in April and May 2007. This paper describes the investigation and highlights the importance of multidisciplinary collaboration for successful control of such outbreaks. There was a temporal cluster of 12 confirmed symptomatic cases of VTEC O157 and one asymptomatic carrier, from five families. The investigation revealed that four of these cases formed part of an outbreak involving two families who visited an open farm. The phenotypic and genotypic characteristics of the isolates from the two families and the putative farm animal contacts were indistinguishable, indicating that the animals were the source of the primary infections. No epidemiological link could be established between the remaining three families affected and the open farm or people having visited the farm. Control measures included improved hand washing facilities on the farm, information for visitors and staff, restricted access and suspended petting and feeding of animals, and thorough cleaning and disinfection of affected areas.

Abstract
Due to ongoing technological advances, the range of clinical applications for diffusion-weighted MR imaging has expanded to now include abdominal pathology. Current applications for liver pathology include two main directions. First, oncologic imaging with detection, characterization and follow-up of lesions. Second, evaluation of diffuse liver diseases, including hepatic fibrosis. The diagnostic impact and role of diffusion-weighted MR imaging remain under investigation, but appear promising. Because of its short acquisition time, sensitivity, and additional information it provides, diffusion-weighted MR imaging should be included in routine liver imaging protocols.

Abstract
Ornithomimosaurs (ostrich-mimic dinosaurs) are a common element of some Cretaceous dinosaur assemblages of Asia and North America. Here, we describe a new species of ornithomimosaur, Beishanlong grandis, from an associated, partial postcranial skeleton from the Aptian-Albian Xinminpu Group of northern Gansu, China. Beishanlong is similar to another Aptian-Albian ornithomimosaur, Harpymimus, with which it shares a phylogenetic position as more derived than the Barremian Shenzhousaurus and as sister to a Late Cretaceous clade composed of Garudimimus and the Ornithomimidae. Beishanlong is one of the largest definitive ornithomimosaurs yet described, though histological analysis shows that the holotype individual was still growing at its death. Together with the co-eval and sympatric therizinosaur Suzhousaurus and the oviraptorosaur Gigantraptor, Beishanlong provides evidence for the parallel evolution of gigantism in separate lineages of beaked and possibly herbivorous coelurosaurs within a short time span in Central Asia.

Abstract
Unilateral pulmonary anomalies are rare events of unknown etiology and large clinical variability. Neonatal history does not allow for a reliable prognosis. Interdisciplinary mangament includes prenatal diagnostics and obstetrics, genetics, neonatology, pediatric cardiology and surgery as well as pediatric orthopedics. Neonatal history and long-term follow-up in three patients are presented here including a discussion of prenatal diagnostics and the embryo-genetic basics of lung development. In three term neonates the diagnoses of unilateral pulmonary agenesis, aplasia and dysplasia, respectively, were based on angiography, MRI and bronchoscopy. Neonatal presentation and long-term consequences were studied in the context of the current literature. Neonatal complications ranged from mild repiratory distress to pulmonary failure requiring mechanical ventilation. One patient developed scoliosis on long-term follow-up. Cardiac failure or pulmonary hypertension did not occur during follow-up, in one case lung malformation was accompanied by VACTER-association. Unilateral lung malformation is frequently associated with other, singular or complex anomalies (e.g., renal and vascular). A possible relationship to disrupted regulation of embryo-genetic factors such as T-BOX genes, PITX2 and growth factors ( FGF10), which regulate ASYMMETRICAL pulmonary morphogenesis is discussed. Disruptive unilateral pulmonary malformations may serve as a model for embryological lung development and other anomalies (e.g., congenital diaphragmatic hernia, unilateral hypoplasia and CCAM). Prenatal diagnosis is characterized by unilateral hyperechogenicity of the affected lung. Neonatal presentation is determined by mediastinal shift which may be corrected by tissue-expander implantation. Associated anomalies require cytogenetic analysis and sequencing of currently known mutations. Long-term follow-up by echocardiography and pulmonary function testing is mandatory in these patients.

Abstract
We report the case of a 41-year-old man admitted for lower limb and liver trauma following a car accident. Surgical repair of a tibial fracture was performed under general anesthesia 5 days after admission while the liver injury was managed conservatively. At the time of tourniquet inflation, the patient presented a pulmonary embolism. Low-molecular-weight heparin administration had been delayed for 72 hours after admission due to the liver injury.

Abstract
OBJECTIVE Local recurrence of pelvic cancer is a therapeutic challenge. The purpose of the study was to evaluate radiofrequency ablation (RFA, intra-operative or CT-guided) for the treatment of pelvic recurrence in patients not eligible for curative surgical resection. METHOD Charts of all patients treated for pelvic recurrence by RFA between March 2004 and March 2005 were reviewed. RESULTS Eight patients (two females) had RFA for inoperable local recurrence [rectal adenocarcinoma (six) and sarcoma (two)]. Surgical resection of the primary tumour had been performed at a median age of 50.2 (36.7-61.6) years. Recurrence occurred after a median of 49.5 (11.7-63.5) months. The mean size of the recurrence was 33.4 (20-45) mm. RFA was given on a median number of two occasions (1-3). Complications occurred in six patients including minor pain [pelvic (six); sciatic nerve irritation (four)]; ureteric obstruction requiring stenting (two) and colo-vesical fistula (one), requiring ileal urinary diversion. After a median follow-up of 18.2 months (11-32), six patients were still alive. Patients, who had experienced pain prior to RFA were pain-free. Five patients showed evidence of further tumour growth but were asymptomatic. CONCLUSION Radiofrequency ablation is a feasible therapeutic option for recurrent pelvic cancer. It allows good symptom control in patients with pain but morbidity is high.

Abstract
PURPOSE The quality of magnetic resonance cholangiopancreatography (MRCP) images is frequently degraded by high signal from the gastrointestinal tract on heavily T2W images. The purpose of this study is to evaluate pineapple juice (PJ) as an oral negative contrast agent in MRCP. MATERIALS AND METHODS Results from MRCP in 50 patients with PJ and 50 patients with paramagnetic contrast (ferumoxsil-Lumirem) were compared. Reviewers were blinded to the type of contrast agent. Exam quality was recorded with regards to signal suppression in the stomach, duodenum and proximal small bowel and with regards to pancreatic duct and biliary ducts visualization. In vitro, the signal characteristics of several commercially available brands of PJ were assessed using T1W, T2W and MRCP sequences. Signal intensity was correlated with the manganese concentration measured using atomic absorption spectrometry. Finally, the reviewers compared the taste of PJ and ferumoxsil. RESULTS On MRCP sequences, results were similar with regards to signal suppression in the stomach, duodenum and proximal small bowel with PJ and ferumoxsil. Visualization of the pancreatic duct, intrahgepatic bile ducts and CBD was similar with PJ and ferumoxsil. The signal intensity of commercially available brands of PJ on T2W and MRCP sequences correlated well with the measured manganese concentration on spectroscopy. Variations in manganese concentration were observed, with values ranging from 3.65 to 27.24 mg/L. The reviewers noted that PJ tasted "good" or "very good" and that ferumoxsil tasted "bad" or "very bad". CONCLUSION Ingestion of PJ provides effective signal suppression in the GI tract on MRCP, similar to paramagnetic contrast agents. Because manganese concentration is highly variable in commercially available PJ brands, a brand with high manganese concentration should be selected.

Abstract
In recent years, autoimmune pancreatitis (AIP) has been increasingly recognized. It can be associated with diabetes mellitus and other systemic autoimmune diseases, or with bile ducts lesions, which are also responsive to steroid therapy as pancreatic lesions. We report the case of a 34-year-old man with a history of a first acute pancreatitis, attributed to an intraductal papillary-mucinous neoplasm of the pancreas (IPMN) with segmental involvement of the main pancreatic duct. A spleno-pancreatectomy was performed, and pathological examination of the specimen diagnosed autoimmune pancreatitis. A treatment with corticosteroids was carried out. To our knowledge, this is the first reported case of AIP mimicking IPMN of the main pancreatic duct.

Abstract
The BK virus is a ubiquitous member of the group of human polyoma viruses that commonly is reactivated in the setting of immunosuppression related to renal transplantation, which results in tubulointerstitial nephritis and allograft dysfunction. BK virus-associated nephropathy occurring in association with human immunodeficiency virus infection and acquired immunodeficiency syndrome (AIDS) was reported only rarely. We describe the case of a 43-year-old man with AIDS presenting with nonoliguric renal failure. The renal biopsy specimen showed tubulointerstitial nephritis and renal tubular cell changes consistent with BK viral inclusions. Results of in situ hybridization for BK viral DNA were positive and showed tubular cell intranuclear inclusions. To our knowledge, this represents the third case of AIDS-associated BK virus-associated nephropathy diagnosed by means of biopsy.

Abstract
We report a measurement of the Lambda(b)(0) lifetime using a sample corresponding to 1.3 fb(-1) of data collected by the D0 experiment in 2002-2006 during run II of the Fermilab Tevatron collider. The Lambda(b)(0) baryon is reconstructed via the decay Lambda(b)(0)-->micronuLambda(c)(+)X. Using 4437+/-329 signal candidates, we measure the Lambda(b)(0) lifetime to be tau(Lambda(b)(0))=1.290(-0.110)(+0.119)(stat)(-0.091)(+0.087)(syst) ps, which is among the most precise measurements in semileptonic Lambda(b)(0) decays. This result is in good agreement with the world average value.

Abstract
Mixed epithelial stromal tumor of the kidney (MEST)/adult cystic nephroma (CN) is a lesion characterized by epithelial lined tubular or cystic structures interspersed within a variably prominent, distinctive spindle-cell stroma. Although typically benign, cases with malignant features have been reported. Herein, we report a MEST/CN with malignant stromal features and rhabdoid differentiation arising in the left kidney of an 84-year-old woman. Histologically, the tumor displayed multiple tubules and variably sized cystic structures lined by benign epithelium with an intervening malignant-appearing spindle-cell stroma. The malignant stroma displayed condensation in the regions surrounding the epithelial component consistent with the ovarian-like stroma typically observed in MEST/CN. In addition, the stromal cells displayed extensive rhabdoid differentiation. Immunohistochemical analysis revealed strong expression of cytokeratin 7, CAM 5.2, AE1/AE3, wide-spectrum keratin, and epithelial membrane antigen by the epithelial component. The stromal component displayed strong immunohistochemical expression of WT-1, CD-99, CD-56, INI1, and estrogen receptor; focal actin positivity; and was negative for desmin, myogenin, and progesterone receptor. Analysis by reverse transcriptase polymerase chain reaction failed to identify the SYT-SSX1 or SYT-SSX2 fusion transcripts characteristic of synovial sarcoma. To our knowledge, this represents the first report in the literature of malignant MEST with rhabdoid features and suggests that this entity should be considered in the diagnosis of renal stromal malignancies with prominent rhabdoid features.

Abstract
The imaging features of infectious and non-infectious pathologies in HIV patients with AIDS (less than 200 CD4/mm3) are illustrated. Opportunistic infections, tumors and vascular pathologies have variable appearances based on the degree of immunosuppression and patient compliance with opportunistic infection prophylaxis. Because of advances in retroviral treatments and wider use of anti-infectious prophylaxis, thoracic pathologies in AIDS patients are less frequent but must nonetheless be recognized, and diagnosis should be suggested in patients with unknown serologic status.
