INTRODUCTION: Clinical presentations of prolactinomas are quite different between genders. In comparison with women's prolactinoma, those in men showed predominance of large tumors with high prolactin (PRL) levels. This preponderance could be attributed to a greater proliferative potential of the tumors. Differences in magnetic resonance imaging (MRI) signal at diagnosis have not been yet clearly evaluated. METHODS: We conduct a retrospective study comparing MRI signal intensity (SI) on T2-weighted images (T2-WI) between 41 men and 41 women to investigate whether or not men prolactinoma present specific features. RESULTS: In addition to the size of the adenoma and PRL levels (P < 0001), prolactinomas in men also exhibit differences from those in women in signal on T2-WI on MRI (P < 0001). Women's prolactinomas are mostly of high SI on T2-WI while men's prolactinomas exhibit a more heterogeneous pattern of SI on T2-WI. Prolactinomas presenting with low SI on T2-WI are almost exclusively encountered in men. CONCLUSIONS: Presence of T2-WI hypointensities in pituitary adenoma can be predictive of a different subtype of prolactinoma almost encountered in men and possibly translate the presence of spherical amyloid deposits, in agreement with the literature.

BACKGROUND: Multiple Endocrine Neoplasia syndrome type 1 (MEN1), which is secondary to mutation of the MEN1 gene, is a rare autosomal-dominant disease that predisposes mutation carriers to endocrine tumors. Most studies demonstrated the absence of direct genotype-phenotype correlations. The existence of a higher risk of death in the GTE-cohort associated with a mutations in the JunD interacting domain, suggests heterogeneity across families in disease expressivity. This study aims to assess the existence of modifying genetic factors by estimating the intra-familial correlations and heritability of the six main tumor types in MEN1. METHODS: The study included 797 patients from 265 kindred and studied seven phenotypic criteria: parathyroid and pancreatic neuroendocrine tumors (NETs), pituitary, adrenal, bronchial and thymic tumors (ThNETs) and the presence of metastasis. Intra-familial correlations and heritability estimates were calculated from family tree data using specific validated statistical analysis software. RESULTS: Intra-familial correlations were significant and decreased along parental degrees distance for pituitary, adrenal and th-NETs. The heritability of these three tumor types was consistently strong and significant with 64% (Standard Error [SE]=0.13; p < 0.001) for pituitary tumor, 65% (SE=0,21; p < 0.001) for adrenal tumors, and 97% (SE=0.41; p=0.006) for thNETs. CONCLUSION: The present study shows the existence of modifying genetic factors for thymus, adrenal and pituitary MEN1 tumor types. The identification of at-risk subgroups of individuals within cohorts is the first step towards personalization of care. Next generation sequencing on this subset of tumors will help identify the molecular basis of MEN1 variable genetic expressivity. [less ▲]

Light pollution is defined as the abnormal and disturbing presence of light and its adverse consequences on flora, faunae, ecosystems and its suspected or proven effects on human health. Light pollution is a quite recent and increasing phenomenon within our society and it leads to a major environmental damage, obviously near wildlife, but also on human health (cancers, obesity, fatigue, depression...). The solutions to this problem are however simple, efficient and de facto inexpensive and involving a substantial energy saving. [less ▲]

Gigantism and acromegaly, usually caused by a pituitary adenoma linked innapropriate secretion of growth hormon (GH) are generally considered as very rare diseases, even if, regarding some authors, their cumulative prevalence is about 1/5000. Starting from the historical case of a giant from Liège we will describe the different types of GH pituitary adenomas and their physiopathology. We will overall discuss rare forms of inherited GH secreting pituitary adenomas like the FIPA (familial inherited isolated pituitary adenomas) and the X-LAG (X linked acrogigantism), both described in Liège, respectively in 2000 and 2014.

Despite being a classical growth disorder, pituitary gigantism has not been studied previously in a standardized way. We performed a retrospective, multicenter, international study to characterize a large series of pituitary gigantism patients. We included 208 patients (163 males; 78.4%) with growth hormone excess and current/previous abnormal growth velocity for age or final height >2SD above country normal means. The median onset of rapid growth was 13.0 years and occurred significantly earlier in females than in males; pituitary adenomas were diagnosed earlier in females than males (15.8 vs. 21.5 years, respectively). Adenomas were >/=10 mm (i.e. macroadenomas) in 84%, of which extrasellar extension occurred in 77% and invasion in 54%. GH/IGF-1 control was achieved in 39% during long-term follow-up. Final height was greater in those with younger age of onset, with larger tumors and higher GH levels. Later disease control was associated with a greater difference from mid-parental height (r=0.23, P=0.02). AIP mutations occurred in 29%; microduplication at Xq26.3 -X-linked acro-gigantism (X-LAG)- occurred in two familial isolated pituitary adenoma (FIPA) kindreds and in ten sporadic patients. Tumor size was not different in X-LAG, AIP mutated and genetically-negative patient groups. AIP-mutated and X-LAG patients had significantly younger age at onset and diagnosis, but disease control was worse in genetically-negative cases. Pituitary gigantism patients are characterized by male predominance and large tumors that are difficult to control. Treatment delay increases final height and symptom burden. AIP mutations and X-LAG explain many cases, but no genetic etiology is seen in >50% of cases. [less ▲]
