Current state of knowledge on neuroendocrine small bowel tumours: non-systematic review of the literature based on one case.

More than 60% of neuroendocrine tumours, also called carcinoids, are localised within the gastrointestinal tract. Small bowel neuroendocrine tumours have been diagnosed with increasing frequency over the past 35 years, being the second most frequent tumours of the small intestine. Ileal neuroendocrine tumours diagnosis is late because patients have non-specific symptoms. We have proposed to illustrate as an example the case of a patient, and on its basis, to make a brief review of the literature on small bowel neuroendocrine tumours, resuming several recent changes in the field, concerning classification criteria of these tumours and new recommendations and current advances in diagnosis and treatment. This patient came to our emergency department with a complete bowel obstruction, along with a 2-year history of peristaltic abdominal pain, vomits and diarrhoea episodes. During emergency laparotomy, an ileal stricture was observed, that showed to be a neuroendocrine tumour of the small bowel.

Application of direct-infusion ESI-MS/MS for toxicological screening.

BACKGROUND: Direct-infusion ESI-MS/MS is a powerful approach for the identification of substances in complex mixtures. The aim of this work was to investigate its applicability to the toxicological screening of blood samples. A simple protein precipitation was used, followed by a 15 min infusion of the extract in the mass spectrometer. RESULTS: The application of the procedure to commercial quality controls and authentic post-mortem blood samples demonstrated that the direct-infusion ESI-MS/MS approach enables the simultaneous identification of substances that require different chromatographic conditions. However, poor sensitivity was observed for benzodiazepine, amphetamines and opiate compounds. CONCLUSION: Considering the facile implementation and positive performance of direct-infusion ESI-MS/MS, this approach may to be a valuable complementary technique for systematic toxicological analysis procedures.

Antagonistes de l'angiotensine II et cancer: un bilan rassurant [Angiotensin II receptor blockers (ARBs) and cancer: a reassuring balance].

The effects of drugs on new cancer and cancer-related death are a major concern. Recently, a meta-analysis raised the possibility that ARBs might have an adverse impact in this respect. This point of view was highly debated until the publication of two other meta-analyses which did not demonstrate any increased risk of new cancer occurrence as well as of cancer related-death with the use of ARBs in patients with hypertension, heart failure and/or nephropathy. This illustrates that the results of meta-analyses should be interpreted cautiously and critically in order to avoid biased conclusions. Overall the bulk of evidence today indicates that ARBs are not associated with an increased cancer risk.

Pulmonary inflammatory myofibroblastic tumour after Hodgkin's lymphoma.

Positron emission tomography (PET)/CT plays a major role in staging, assessing response to treatment and during follow-up of paediatric Hodgkin's lymphoma (HL). Owing to high sensitivity to detect viable tumoural tissue, negative PET/CT is highly predictive of survival. However, (18)F-FDG is not specific for malignant disease and may concentrate in numerous benign/inflammatory lesions that may cause 'false-positive' results and follow-up PET/CT studies should be interpreted with caution. We report a case of pulmonary inflammatory myofibroblastic tumour, which developed during follow-up in a young patient with complete remission of a stage IIB HL and was fully treated with surgical resection.
