Meningiomas are common, usually benign tumors of the central nervous system that have a high rate of post-surgical recurrence or regrowth. We determined expression of the proteins merlin, NDRG2, ERBB2, and c-MYC in meningiomas using immunohistochemistry and assessed relationships between protein expression and gender, age, tumor grade, and recurrence or regrowth. The study sample comprised 60 patients, (44 women and 16 men) with a mean age of 53.2±12.7 years. Tumors were classified as grade I (n=48) or grades II and III (n=12). Expression of merlin, NDRG2, ERBB2, and c-MYC was not significantly different statistically with relation to gender, age, or meningioma recurrence or regrowth. Merlin was expressed in 100% of the cases. No statistically significant difference between tumor grade and recurrence or regrowth was identified. Statistically significant differences were identified between the mean age of patients with grade I (54.83±11.60) and grades II and III (46.58±15.08) meningiomas (P=0.043), between strong c-MYC expression and grades II and III (P<0.001), and between partial surgical resection and tumor recurrence or regrowth (P<0.001). These findings reveal the lower mean age among grades II and III meningioma patients than grade I patients, the influence of the protein merlin on tumorigenesis, the association of c-MYC with aggressive meningiomas, and that partial surgical resection is associated with tumor recurrence or regrowth.

Prolactin (PRL) secreting adenomas are associated with high incidence of headache. The role of hyperprolactinemia in the headache context is not clear, nor is the effect of its treatment on headache. Methods: The present longitudinal study evaluated hyperprolactinemic patients (69), in terms of presence and characteristics of headache before and after hyperprolactinemia treatment. Results: Headache was reported by 45 (65.2%) patients, independent of the etiology of hyperprolactinemia. The migraine phenotype was the most prevalent (66.6%). Medications used in the treatment of headache not changed during the study. The first line of treatment of hyperprolactinemia was dopaminergic agonists. In the last reevaluation, PRL level under treatment was within the reference range in 54.7% of the cases, and it was observed complete or partial resolution of the headache in 75% of the cases. The median PRL at this time in patients with complete headache resolution was 17 ng/mL, in those who reported partial recovery was 21 ng/mL, and in those in whom the headache did not change was 66 ng/mL, with a significant difference between the group with complete headache resolution vs. the group with unchanged headache (p=0.022). In the cases with complete headache resolution, the median fall on PRL levels was 89% and in those cases with partial headache resolution 86%, both significantly different (p<0.001) from the fall in the cases with an unchanged headache. Conclusion: Data allow us to conclude that, in this series, in the majority of cases the reduction in the level of PRL was followe3d by cessation or relief of the pain.

Introduction: Acromegaly is associated with high morbidity, but still controversial impact on the overall quality of life (QoL). Material and Methods: We evaluated QoL using a generic (SF-36) and a disease-specific questionnaire (AcroQoL) in an acromegalic cohort. Results: Sixty-nine patients answered the questionnaires and had their records reviewed. In the SF-36 questionnaire, except for the Social Aspects domain, all others revealed a reduction in scores from 9.7 to 38.9%, when compared to the non-acromegalics. The cure was positively correlated with mental health ( P = 0.023) and drug control was correlated with mental health ( P = 0.023) and functional capacity ( P = 0.013). In the AcroQoL questionnaire, the mean scores ranged from 54.7% to 72.8%. The use of antidepressants correlated with lower scores on the total AcroQoL ( P = 0.039) and physical complaints ( P = 0.003). The growth hormone value at diagnosis showed an inverse correlation with the total AcroQoL score ( P = 0.014), Appearance Issues subscale ( P = 0.081), and Personal Relations ( P = 0.002). IGF-1 values at diagnosis and at the last visit showed no statistical correlation with any of the questionnaires. Conclusion: The finding of a reduction in QoL scores with both SF-36 and AcroQoL allows us to suggest this evaluation as part of the initial assessment and follow-up in acromegaly, to act globally on the individual's health condition.
