Hopkins Jennifer, Pardo Mariana, Bischoff Karyn
INTRODUCTION: 5-Hydroxytryptophan (5-HTP) supplements are available over the counter and labeled as sleeping aids and anxiolytics for human use. 5-HTP is a serotonin precursor and overdose can lead to serotonin syndrome. CASE REPORT: A 9-month-old female Labrador retriever was evaluated after ingestion of a 5-HTP supplement. Signs of agitation developed within 1 h of ingestion, and emesis was attempted by the owner with  3% hydrogen peroxide (H2O2) orally. On presentation, the dog was obtunded, bilaterally mydriatic and salivating...

M Kaplan, R J Wong, D K Stevenson
The role of genetic factors in the modulation of serum bilirubin levels and the pathophysiology of neonatal hyperbilirubinemia is being increasingly recognized. Heme oxygenase-1 (HO-1) is the rate-limiting enzyme by which heme is catabolized to biliverdin and thence to bilirubin, with the simultaneous release of equimolar quantities of ferrous iron (Fe(3+)) and carbon monoxide. Polymorphisms of the HO-1 gene promoter may modulate transcriptional activity, thereby augmenting or attenuating HO-1 expression with resultant modulation of the production of bilirubin...

BACKGROUND: Jaundice due to biliary obstruction leads to multiple physiologic derangements and a decline in performance status that may result in unfavorable intra- and postoperative outcomes following a Whipple procedure. While preoperative biliary decompression may improve synthetic function, this strategy has been reported to increase the incidence of infectious complications following surgery. We hypothesized that hyperbilirubinemia at the time of pancreatoduodenectomy (PD) would be a risk factor for increased morbidity and mortality postoperatively...

BACKGROUND: Advanced cholangiocarcinoma carries a poor prognosis, and no standard treatment exists beyond first-line gemcitabine/platinum-based chemotherapy. A single-arm, phase 2 and biomarker study of cabozantinib, a multikinase inhibitor with potent activity against vascular endothelial growth factor receptor 2 (VEGFR2) and MET, was performed for patients with advanced refractory cholangiocarcinoma. METHODS: Previously treated patients with unresectable or metastatic cholangiocarcinoma received cabozantinib (60 mg orally and daily on a continuous schedule)...

BACKGROUND: The use of transcutaneous bilirubin (TcB) as a screening tool, based on relevant population-specific nomogram, or proxy for total serum bilirubin (TSB) levels in assessing the risk of subsequent hyperbilirubinemia is supported by several clinical guidelines on the management of neonatal hyperbilirubinemia. However, while TcB has been found to significantly over-estimate TSB in neonates of African-American ancestry, with variations across TcB devices, no nomogram has been specifically reported for this racial group...

BACKGROUND: Hyperbilirubinemia guidelines are based on total serum bilirubin (TSB), in combination with either gestational age (GA) or birth weight (BW), postnatal age and specific risk factors. However, TSB is a poor predictor of bilirubin-induced neurotoxicity (BIND). Free unconjugated bilirubin (UCBfree) and the UCBfree/TSB ratio are more directly related to BIND, but data on their postnatal courses are unknown. AIMS: To characterize the postnatal courses of UCBfree and UCBfree/TSB ratio, and assess their relationships with clinical characteristics...

Severe neonatal hyperbilirubinemia (SNH) and the onset of bilirubin encephalopathy and kernicterus result in part from delayed expression of UDP-glucuronosyltransferase 1A1 (UGT1A1) and the inability to metabolize bilirubin. Although there is a good understanding of the early events after birth that lead to the rapid increase in serum bilirubin, the events that control delayed expression of UGT1A1 during development remain a mystery. Humanized UGT1 (hUGT1) mice develop SNH spontaneously, which is linked to repression of both liver and intestinal UGT1A1...

Jaundice in adults can be an indicator of significant underlying disease. It is caused by elevated serum bilirubin levels in the unconjugated or conjugated form. The evaluation of jaundice relies on the history and physical examination. The initial laboratory evaluation should include fractionated bilirubin, a complete blood count, alanine transaminase, aspartate transaminase, alkaline phosphatase, ?-glutamyltransferase, prothrombin time and/or international normalized ratio, albumin, and protein. Imaging with ultrasonography or computed tomography can differentiate between extrahepatic obstructive and intrahepatic parenchymal disorders...

A 56-year-old man with no abnormalmedicalhistory was admitted to our hospitalfor gastric cancer surgery. The preoperative laboratory tests indicated anemia, hyperbilirubinemia, hemagglutinin reaction, and a markedly high cold agglutinin titer; thus, we diagnosed the patient with cold agglutinin disease(CAD). Although perioperative complications caused by cold stimulation were suspected, we decided that it was possible to perform the operation under robust intraoperative conditions avoiding exposure to cold temperatures, and thus performed the radical operation...

Extreme hyperbilirubinemia and kernicterus, though rare, continue to occur despite the adoption of universal screening. Unless they are known to have glucose-6-phosphate dehydrogenase deficiency, infants who currently develop kernicterus in high resource countries are often otherwise healthy newborns discharged from the well-baby nursery. In this review, we highlight risk factors that increase the risk of a newborn ≥35 weeks gestational age developing severe hyperbilirubinemia, as well as the risk factors that increase the hyperbilirubinemic infant's risk of kernicterus...
