  • Acute lymphoblastic leukemia presenting as cholestatic jaundice in a 7-year-old boy. [Case Reports]
    SAGE Open Med Case Rep 2019; 7:2050313X19875318Ford J, Rainey S, … Kendhari H
  • This is a case of a 7-year-old boy with acute lymphoblastic leukemia presenting with cholestasis and elevated transaminase levels. Acute lymphoblastic leukemia is the most common malignancy in children and can have variable presenting clinical manifestations. However, cholestasis is less commonly encountered in the pediatric population and can be a diagnostic challenge. We present a case of a 7-y…
  • Optimizing neural networks for medical data sets: A case study on neonatal apnea prediction. [Journal Article]
    Artif Intell Med 2019; 98:59-76Shirwaikar RD, Acharya U D, … Lewis U LES
  • CONCLUSIONS: The study shows that an MLP model can undergo significant improvements in predictive performance, by the proposed step-wise optimization. The optimized MLP is proved to be as accurate as deep neural network models such as Deep Belief Networks and Deep Auto-encoders for noisy and nonlinear data sets, and outperform all conventional models like Support Vector Machine (SVM), Decision Tree (DT), K Nearest Neighbor and Random Forest (RF) algorithms. The generic nature of the proposed step-wise optimization provides a framework to optimize neural networks on such complex nonlinear datasets. The investigated models can help neonatologists as a diagnostic tool.
  • Bile duct involvement by hepatocellular carcinoma: A rare occurrence and poor prognostic indicator in bile duct brushing samples. [Journal Article]
    Cancer Cytopathol 2019Bhattarai S, Graham RP, … Reid MD
  • CONCLUSIONS: HCC may extend into the intrahepatic and/or extrahepatic biliary tree, causing masses and/or strictures that may be sampled on BDB. Although cytologically malignant, the classic features of HCC are uncommon, which can cause misdiagnosis. Cytopathologists should be mindful of this differential when evaluating BDBs, particularly when concomitant liver masses and/or HCC risk factors are present. Because of the associated high mortality and rapid rate of death, its presence should be conveyed clearly in pathology reports.
  • Diverticulum of common hepatic duct leading to obstructive jaundice, a case report. [Journal Article]
    BJR Case Rep 2019; 5(2):20180105Tarallo N, Curti M, … Fugazzola C
  • Choledochal cyst is a dilation of the intrahepatic and/or extrahepatic biliary tree. The pathogenesis is unknown and potentially is multifactorial. In 1977, Todani classified the cysts under five different types according to their morphology, number and distribution along the biliary tree. Presenting symptoms of Choledocal cysts which include upper abdominal pain, acute cholangitis and jaundice, …
  • Intraductal papillary mucinous neoplasm of the biliary tract: a lesion of the bile duct lumen. [Journal Article]
    Rev Esp Enferm Dig 2019; 111Sánchez Rodríguez E, Caminoa Lizarralde A, … Vázquez Sequeiros E
  • Intraductal papillary neoplasm of the bile duct (IPNB) is a rare entity characterized by papillary growth within the bile duct lumen1, currently regarded as a biliary counterpart of intraductal papillary mucinous neoplasm of the pancreas. The most common clinical findings are abdominal pain, jaundice or cholangitis, although some patients are asyntomatic. The diagnosis requires careful assessment…
  • Leptospirosis With Acute Renal Failure and Vasculitis: A Case Report. [Case Reports]
    Arch Rheumatol 2019; 34(2):229-232Yücel Koçak S, Kudu A, … Apaydin S
  • Leptospirosis is a zoonotic disease that occurs worldwide. Various clinical manifestations of leptospirosis can be seen. In this article, we present a case with acute renal failure, severe vasculitis and hyperbilirubinemia occurring simultaneously with leptospirosis. A 45-year-old male patient presented with fever, myalgia, jaundice and reddish skin lesions and anuria. Physical examination findin…
