Objectives: Nightmares can be defined as "an unpleasant dream with anxiety and oppression". They represent a symptom possibly leading to serious psychiatric and physical consequences. It occurs to 2% to 8% of the general population. Lucid dreaming therapy (LDT) is an interesting upcoming psychotherapy for the treatment of nightmares. The aim of this study was to evaluate the efficacy of LDT in the treatment of nightmares in adults and children., Methods: We performed a systematic review of the literature, based on the Cochrane organisation's methodology. We explored the PubMed, Cochrane library, PsycINFO via Ovid and Embase databases and clinical trial registries (CTR), namely clinicaltrials.gov, EU clinical trials and the WHO clinical trials registry platform., Results: Four randomized controlled trials (RCT), 2 case series and 5 case reports were included. Most of the included studies found LDT effective in reducing nightmare frequency among adults with chronic and recurring nightmares. We did not identify any reports in children., Conclusions: Despite a limited internal validity for the included studies, these first results are encouraging. Nonetheless, larger and more rigorous studies would allow to better assess the utility of LDT for nightmares., (Copyright © 2023 L'Encéphale, Paris. Published by Elsevier Masson SAS.

Objective and Methods: epidural localization is a rare presenting sign of non Hodgkin's lymphoma. In this study, we describe the clinical, histological and immunohistochemical data in 13 cases (9 men and 4 women) of non-Hodgkin's lymphoma with epidural involvement., Results: the median age was 63 years (range 36-76 years). Clinically, most patients complained of back pain (median duration, 3.4 months) followed by acute neurological deterioration. In 10 out of 13 tumors, a thoracic localization was observed and a decompressive laminectomy was performed in all cases. Histology and immunohistochemistry showed all tumors to be B-cell lymphomas which were classified as: lymphocytic lymphoma (3 cases), prolymphocytic lymphoma (1 case), follicular lymphoma (2 cases), diffuse large cell lymphoma (6 cases) and AIDS associated Burkitt lymphoma (1 case). Post-operative staging revealed bone and/or paravertebral involvement in 11 cases and disseminated disease in 5 cases. Median survival following complementary therapy, radiotherapy and chemotherapy in most cases, was 20 months., Conclusion: histological features of epidural lymphomas are similar to other extranodal lymphomas and their prognosis is better than other epidural neoplasms, especially when the tumor is localized.

Arterial endofibrosis is a rare disease usually affecting the external iliac artery in highly trained athletes. We report a case of bilateral external iliac endofibrosis in a 44-year-old cyclist. Microscopic examination of the resection specimen showed an isolated thickening of the arterial intima, and confirmed the diagnosis of this entity of unknown etiology.

Pancreatic neuroendocrine tumors are rare in von Hippel-Lindau disease, most often asymptomatic, nonfunctioning, non secreting, and benign. We report a case of low grade malignant pancreatic, secreting and asymptomatic neuroendocrine tumors, occurring in a 27 year old woman in the setting von Hippel-Lindau disease with recurrent pheochromocytoma, retinal and medullary hemangioblastomas, paraganglioma of the carotid body and ovarian cystadenoma. Neuroendocrine pancreatic tumors of von Hippel-Lindau disease are often constituted by clear cells, in the contrary of other neuroendocrine tumors of the pancreas. Occurrence of a pancreatic neuroendocrine tumor, especially in association with pheochromocytoma, may be misdiagnosed with a type 2 multiple endocrine neoplasia syndrom instead of von Hippel-Lindau disease.
