Acute Liver Failure as an Index Presentation of Hematolymphoid Malignancy: A Rare Case Report.

Acute liver failure (ALF) is usually due to viral hepatitis and toxins. We have recently seen a patient with diffuse large B-cell lymphoma (DLBCL) presenting with ALF. High clinical suspicion is necessary for making a diagnosis of this rare etiology presenting as ALF. The outcome is better if an early diagnosis is made in such cases and appropriate treatment is initiated.

Adequacy of sigmoidoscopy as compared to colonoscopy for assessment of disease activity in patients of ulcerative colitis: a prospective study.

BACKGROUND/AIMS: Patients of ulcerative colitis (UC) on follow-up are routinely evaluated by sigmoidoscopy. There is no prospective literature to support this practice. We assessed agreement between sigmoidoscopy and colonoscopy prospectively in patients with disease extent beyond the sigmoid colon. METHODS: We conducted a prospective observational study at a tertiary care institute for agreement between sigmoidoscopy and colonoscopy. We assessed endoscopic activity using the Mayo Endoscopic Score (MES) and Ulcerative Colitis Endoscopic Index of Severity (UCEIS) and histological activity using the Nancy Index (NI), Robarts Histopathology Index (RHI), and Simplified Geboes Score (SGS). RESULTS: Sigmoidoscopy showed a strong agreement with colonoscopy for MES and UCEIS with a kappa (κ) of 0.96 and 0.94 respectively. The misclassification rate for MES and UCEIS was 3% and 5% respectively. Sigmoidoscopy showed perfect agreement (κ = 1.00) with colonoscopy for assessment of the presence of endoscopic activity in the colon using MES ≥ 1 as activity criteria and strong agreement (κ = 0.93) using MES > 1 as activity criteria. Sigmoidoscopy showed strong agreement with colonoscopy for assessment of the presence of endoscopic activity using UCEIS (κ = 0.92). Strong agreement was observed between sigmoidoscopy and colonoscopy using NI (κ = 0.86), RHI (κ = 1.00), and SGS (κ = 0.92) for the detection of histological activity. The misclassification rate for the detection of histological activity was 2%, 0%, and 1% for NI, RHI, and SGS respectively. CONCLUSIONS: Sigmoidoscopy showed strong agreement with colonoscopy for endoscopic and histologic disease activity. Sigmoidoscopy is adequate for assessment of disease activity in patients with UC during follow-up evaluation.

A case of giant colonic lipoma removed endoscopically using a modified hybrid technique.

Colonic lipomas are benign adipose tumors and are mostly asymptomatic. They may cause symptoms when their size becomes more than 2 cm. Giant colonic lipoma (GCL) is a rare finding in endoscopy which presents with or without macroscopic ulceration and may lead to iron deficiency anaemia (IDA). The choice of treatment of symptomatic large colonic lipomas has been controversial. Here we are presenting a case of GCL presenting with occult bleeding causing iron deficiency anaemia (IDA). It was removed endoscopically using a combination of noradrenaline, endoloop ligation, and snare cautery technique (modified hybrid technique). Successful removal of the GCL lead to the resolution of IDA. This case report highlights that even GCL can be removed endoscopically, thus surgery can be prevented. Clinical Significance: GCL is an unusual cause of anemia. Modified hybrid endoscopic removal technique improves safety.

Placement of a flow diverter-like stent together with coil embolisation for treatment of pancreatic pseudoaneurysm involving the origin of the gastroduodenal artery.

A pancreatic pseudoaneurysm can occur following an attack of pancreatitis. This occurs due to erosion of the pancreatic or peripancreatic artery by the pancreatic enzyme-rich pancreatic secretion pseudocyst. If left untreated, it may cause massive and even fatal haemorrhage. Interventional radiology with coil embolisation of the pseudoaneurysm is the standard of care in such cases. We describe a patient who developed a pseudoaneurysm involving the origin of the gastroduodenal artery (GDA). This was successfully managed by coil embolisation of the pseudoaneurysm along with placement of a flow diverter-like stent in the common hepatic artery across the origin of the GDA leading to exclusion of the diseased segment.

Disfunção hepática em pacientes de unidade de terapia intensiva médica prevê desfecho desfavorável / Hepatic dysfunction in medical intensive careunit patients predicts poor outcome

ABSTRACT Background: A large number of patients admitted to the medical intensive care unit (MICU) have abnormal liver function tests (LFT). This includes patients with critical illness with or without preexisting liver disease and patients with acute primary liver injury. There are very few studies which have investigated the spectrum of liver disease, clinical profile and outcome in patients admitted to the MICU. Objective To evaluate the occurrence, etiology, clinical profile, laboratory profile and outcome of hepatic dysfunction in patients admitted to the MICU. To evaluate the utility of model for end-stage liver disease (MELD) score on admission as a predictor of adverse short term outcome in patients with hepatic dysfunction admitted in MICU. Methods: It was a prospective observational study, conducted from December 2017 to December 2018 in a tertiary care hospital. Two hundred and two patients admitted to the MICU with LFTs as per the inclusion criteria were analyzed and their short-term outcome at 7 days was studied in relation to various parameters. Results: LFT abnormalities were present in 202/1126 (17.9%) of the patients admitted to MICU. Critical illness associated liver dysfunction was found in 172 (85.2%) patients, chronic liver disease in 11 (5.4%) patients and acute viral hepatitis in 19 (9.4%) patients. Most common symptom was fever (68.3%) followed by vomiting (48.0%). Among LFT abnormalities, elevated transaminases, raised international normalized ratio and high MELD score on admission correlated with poor short-term outcome. Requirement for inotropes and mechanical ventilation correlated with poor short-term outcome. Mortality did not differ significantly between patients with chronic liver disease, patients with acute viral hepatitis and patients with critical illness associated hepatic dysfunction. Hepatic dysfunction in MICU was associated with poor outcome and a high short-term mortality of 56.4% (114/202). Conclusion: Liver function abnormality is common in patients who are admitted to the MICU and its presence is an indicator of poor short-term outcome.

RESUMO Contexto: Um grande número de pacientes internados na unidade de terapia intensiva (UTI) tem testes de função hepática anormais (TFH). Isso inclui pacientes com doença crítica com ou sem doença hepática pré-existente e pacientes com lesão hepática primária aguda. Há poucos estudos que têm investigado o espectro da doença hepática, perfil clínico e desfecho em pacientes admitidos em UTI. Objetivo Avaliar a ocorrência, etiologia, perfil clínico, perfil laboratorial e desfecho de disfunção hepática em pacientes internados na UTI médica. Avaliar a utilidade do modelo para doença hepática em estágio terminal (MELD). Escore na admissão como preditor de desfecho adverso a curto prazo em pacientes com disfunção hepática admitida em UTI. Métodos: Foi realizado um estudo observacional prospectivo, de dezembro de 2017 a dezembro de 2018 em um hospital de atenção terciária. Foram analisados 202 pacientes internados na UTI com TFH conforme os critérios de inclusão e seu desfecho a curto prazo de 7 dias foi estudado em relação a diversos parâmetros. Resultados: Anormalidades dos testes estiveram presentes em 202/1126 (17,9%) dos pacientes internados na UTI. Doença crítica associada à disfunção hepática foi encontrada em 172 (85,2%) pacientes, doença hepática crônica em 11 (5,4%) pacientes e hepatite viral aguda em 19 (9,4%) pacientes. O sintoma mais comum foi a febre (68,3%), seguido de vômito (48,0%) casos. Entre as anormalidades do TFH, transaminases elevadas, INR e escore MELD elevados na admissão correlacionaram-se com desfecho ruim de curto prazo. Exigência de inotrópicos e ventilação mecânica correlacionaram-se com desfecho de curto prazo ruim. A mortalidade não diferiu significativamente entre pacientes com doença hepática crônica, pacientes com hepatite viral aguda e pacientes com doença crítica associada à disfunção hepática. A disfunção hepática em UTI esteve associada a um desfecho ruim e à uma alta mortalidade a curto prazo de 114/202 (56,4%). Conclusão: A anormalidade da função hepática é comum em pacientes que são admitidos nas unidades de tratamento intensivo e sua presença é um indicador de desfecho de curto prazo ruim.
