No international treatment standard for B12 deficiency exists. Current practice predominantly relies on more than 50 years old data. Consequently, this review investigates that we still recommend five injections with 1 mg B12 over 10 days followed by maintenance therapy with 1 mg oral B12 daily or injections, of which the interval is guided by symptom relief rather than normalization of biomarkers.

Effects of Peptide Receptor Radiotherapy in Patients with Advanced Paraganglioma and Pheochromocytoma: A Nation-Wide Cohort Study.

Introduction: Pheochromocytomas and paragangliomas are rare neuroendocrine tumours that originate from chromaffin cells within the adrenal medulla or extra-adrenal sympathetic ganglia. Management of disseminated or metastatic pheochromocytomas and paragangliomas continues to pose challenges and relies on limited evidence.

Method: In this study, we report retrospective data on median overall survival (OS) and median progression-free survival (PFS) for all Danish patients treated with peptide receptor radionuclide therapy (PRRT) with Lu-Dotatate or Y-Dotatate over the past 15 years.

Case of primary low-grade neuroendocrine carcinoma of the skin.

A man presents a 4 mm skin tumour at his general practitioner. The tumour is removed on the suspicion of a dermatofibroma. Important differential diagnoses are sebaceous neoplasms, melanomas, Merkel cell carcinomas and large cell neuroendocrine carcinoma, and metastases of neuroendocrine neoplasms from the gut or lung.

Lower Incidence of Hepatobiliary Cancer in Infected Persons: A Cohort Study of 53.633 Persons.

Background And Aims: (HP) is known to be involved in intestinal carcinogenesis. As regards hepatobiliary cancers, there are few and inconsistent reports. We investigated HP infection and its association with the incidence of hepatobiliary cancers in a large cohort study.

Thyroid Disease and Hepatocellular Carcinoma Survival: A Danish Nationwide Cohort Study.

Introduction: Hepatocellular carcinoma (HCC) is the fourth leading cause of cancer mortality worldwide. Recent animal studies suggest that thyroid hormone treatment improves HCC prognosis. The aim of this study was to describe the association between thyroid disease and HCC prognosis in humans.

Cognitive impairment after liver transplantation: residual hepatic encephalopathy or posttransplant encephalopathy?

Liver transplantation (LT) represents the definitive treatment for end-stage liver disease. Cognitive impairment following LT is frequent, referred to as postliver transplant encephalopathy (PLTE). LT removes the underlying chronic liver disease, and until recently hepatic encephalopathy (HE) was assumed to be fully reversible after LT.

The tissue profile of metabolically active coenzyme forms of vitamin B12 differs in vitamin B12-depleted rats treated with hydroxo-B12 or cyano-B12.

Recent rat studies show different tissue distributions of vitamin B12 (B12), administered orally as hydroxo-B12 (HO-B12) (predominant in food) and cyano-B12 (CN-B12) (common in supplements). Here we examine male Wistar rats kept on a low-B12 diet for 4 weeks followed by a 2-week period on diets with HO-B12 (n 9) or CN-B12 (n 9), or maintained on a low-B12 diet (n 9). Plasma B12 was analysed before, during and after the study.

Update on the Therapeutic Management of Hepatic Encephalopathy.

Purpose Of Review: Hepatic encephalopathy (HE) is a common and devastating complication to chronic liver disease. In this paper, we summarize the latest research and evidence of both conventional and up-coming treatments.

Recent Findings: Meta-analyses report beneficial effects of lactulose, branched-chain amino acids, rifaximin, and to some degree L-ornithine L-aspartate on the manifestations of HE in patients with cirrhosis, and generally the numbers needed to treat are low.

Survival and Predictors of Death for Patients with Bronchopulmonary Carcinoid at a Danish Tertiary NET Centre.

Background/aim: Bronchopulmonary carcinoids comprise of typical carcioids (TC) and atypical carcinoids (AC). We present characteristics and associated mortality in patients with TC and AC followed-up at a Danish NET Centre between 2000-2014.

Patients And Methods: Data were obtained from medical records, computed tomographic scans, and pathology reports.

Tissue distribution of oral vitamin B12 is influenced by B12 status and B12 form: an experimental study in rats.

Purpose: Hydroxocobalamin (HOCbl) is the dominating Cbl form in food, whereas cyanocobalamin (CNCbl) is common in vitamin pills and oral supplements. This study compares single-dose absorption and distribution of oral HO[Co]Cbl and CN[Co]Cbl in Cbl-deficient and normal rats.

Methods: Male Wistar rats (7 weeks) were fed a 14-day diet with (n = 15) or without (n = 15) Cbl.
