TL;DR: A well-coordinated multidisciplinary approach is required in the assessment of suspected cases of biliary atresia, and Histology examination of biopsy specimens plays a pivotal role in the diagnostic evaluation of this disease.
Abstract: Background/aims Extrahepatic biliary atresia (EHBA) is the most important cause of neonatal cholestasis. The validity of different diagnostic methods in the diagnosis of EHBA in developed countries has been presented elsewhere, but data from developing countries with low national incomes are scarce. The aim of this study was to investigate the relative accuracy and roles of abdominal ultrasonography, duodenal tube test (DTT), and liver biopsy in the diagnosis of EHBA in Serbia. Materials and methods The study included 156 infants with cholestasis admitted at the Mother and Child Health Care Institute. Data were collected according to the medical records observation technique. Results Extrahepatic biliary atresia was diagnosed in 72 of 156 infants with cholestasis. The frequency was insignificantly higher in females than in males (1.25:1). Most patients were diagnosed prior to 60 days of life (median 58, range 30-67). In a group of 156 infants with cholestasis, 109 had ultrasound, liver biopsy, duodenal tube test, and intraoperative cholangiography done. Liver biopsy confirmed surgical disease in 71/109 patients and denied it in 38/109 patients (sensitivity- Sn 98%, specificity- Sp 100%, diagnostic efficiency of test- DgEf 99.08%). Duodenal tube test had Sn 97%, Sp 72%, and DgEf 88.99%, and the ultrasound findings showed Sn 78%, Sp 81%, and DgEf 77.92%. Five-year survival rate after Kasai operation was 76%. Conclusion A well-coordinated multidisciplinary approach is required in the assessment of suspected cases of biliary atresia. Histology examination of biopsy specimens is an integral part of the diagnostic algorithm and, therefore, plays a pivotal role in the diagnostic evaluation of this disease.

TL;DR: A case of primary biliary cirrhosis in a 12-year-old girl with characteristic histology features, strongly positive antimitochondrial antibodies, increased liver enzyme levels, increased serum quantitative immunoglobulin M levels, and cholestasis were discovered.
Abstract: Primary biliary cirrhosis (PBC) is a slowly progressive cholestatic liver disease of autoimmune etiology. The initial presentation of PBC is varies from asymptomatic, abnormal liver biochemical tests to overt cirrhosis. Unlike other autoimmune liver diseases, PBC has rarely been reported in childhood. We report a case of primary biliary cirrhosis in a 12-year-old girl. In addition to characteristic histology features, strongly positive antimitochondrial antibodies, increased liver enzyme levels, increased serum quantitative immunoglobulin M levels, and cholestasis were discovered. She had been treated with ursodeoxycholic acid. In the world literature, we found only few pediatric patients of primary biliary cirrhosis. Aetiology, pathogenesis, the long-term natural history, and prognosis remain obscure. Due to increased awareness of early-onset PBC, rather than typical older ones, further pediatric cases may be discovered.

TL;DR: Celiac disease is associated frequently with iron-deficiency anemia, dermatitis herpetiformis, selective IgA deficiency, thyroid disorders, diabetes mellitus, and various connective tissue disorders but is rarely associated with cardiomyopathy.
Abstract: Celiac disease is predominantly a disease of the small intestine characterized by chronic malabsorption in genetically susceptible individuals who ingest grains containing gluten, such as wheat, barley, and rye. Although previously believed to be uncommon, celiac disease may be present in up to 1% of the adult and children population. Celiac disease is associated frequently with iron-deficiency anemia, dermatitis herpetiformis, selective IgA deficiency, thyroid disorders, diabetes mellitus, and various connective tissue disorders but is rarely associated with cardiomyopathy.

TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality. Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

TL;DR: This guideline refers to infants, children, and adolescents ages 0 to 18 years, and indications for diagnostic and therapeutic esophagogastroduodenoscopy and ileocolonoscopy; endoscopy for foreign body ingestion; corrosive ingestion and stricture/stenosis endoscopic management; upper and lower gastrointestinal bleeding; endoscopic retrograde cholangiopancreatography; and endoscopic ultrasonography.
Abstract: This guideline refers to infants, children, and adolescents ages 0 to 18 years. The areas covered include indications for diagnostic and therapeutic esophagogastroduodenoscopy and ileocolonoscopy; endoscopy for foreign body ingestion; corrosive ingestion and stricture/stenosis endoscopic management; upper and lower gastrointestinal bleeding; endoscopic retrograde cholangiopancreatography; and endoscopic ultrasonography. Percutaneous endoscopic gastrostomy and endoscopy specific to inflammatory bowel disease has been dealt with in other guidelines and are therefore not mentioned in this guideline. Training and ongoing skill maintenance are to be dealt with in an imminent sister publication to this.

TL;DR: Among laboratory tests, d-dimer and angiopoietin-2 measurements seem the most useful in early prediction of severe AP, and several anticoagulants that proved beneficial in animal experiments are thus worth testing in patients.
Abstract: Acute pancreatitis (AP) is an inflammatory disease with varied severity, ranging from mild local inflammation to severe systemic involvement resulting in substantial mortality. Early pathologic events in AP, both local and systemic, are associated with vascular derangements, including endothelial activation and injury, dysregulation of vasomotor tone, increased vascular permeability, increased leukocyte migration to tissues, and activation of coagulation. The purpose of the review was to summarize current evidence regarding the interplay between inflammation, coagulation and endothelial dysfunction in the early phase of AP. Practical aspects were emphasized: (1) we summarized available data on diagnostic usefulness of the markers of endothelial dysfunction and activated coagulation in early prediction of severe AP; (2) we reviewed in detail the results of experimental studies and clinical trials targeting coagulation-inflammation interactions in severe AP. Among laboratory tests, d-dimer and angiopoietin-2 measurements seem the most useful in early prediction of severe AP. Although most clinical trials evaluating anticoagulants in treatment of severe AP did not show benefits, they also did not show significantly increased bleeding risk. Promising results of human trials were published for low molecular weight heparin treatment. Several anticoagulants that proved beneficial in animal experiments are thus worth testing in patients.

TL;DR: Although many standalone biochemical markers have been studied for early assessment of severity, C-reactive protein still remains the most frequently used along with Interleukin-6 in the diagnosis and severity evaluation in acute pancreatitis.
Abstract: Acute pancreatitis is a potentially life threatening disease. The spectrum of severity of the illness ranges from mild self-limiting disease to a highly fatal severe necrotizing pancreatitis. Despite intensive research and improved patient care, overall mortality still remains high, reaching up to 30-40% in cases with infected pancreatic necrosis. Although little is known about the exact pathogenesis, it has been widely accepted that premature activation of digestive enzymes within the pancreatic acinar cell is the trigger that leads to autodigestion of pancreatic tissue which is followed by infiltration and activation of leukocytes. Extensive research has been done over the past few decades regarding their role in diagnosis and prognostic evaluation of severe acute pancreatitis. Although many standalone biochemical markers have been studied for early assessment of severity, C-reactive protein still remains the most frequently used along with Interleukin-6. In this review we have discussed briefly the pathogenesis and the role of different biochemical markers in the diagnosis and severity evaluation in acute pancreatitis.
