CaseMale, 44 y.o., with rigth maxillary tumor of progressive growth for 1 year with local and low back pain. Imaging exams: CT/MRI skull and face: right axial expansive lesion (62×52×46 mm), heterogeneous, multiloculated with bulging of the right orbit inferomedial wall, with a neoplastic aspect. CT pelvis: bone lesions with soft tissue densities in pelvis, heterogeneous L4, with height reduction. Biopsy of the lesion suggesting a brown tumor. ...

Introduction: Melnick Needles Syndrome corresponds to a rare skeletal dysplasia of genetic etiology, with dominant inheritance pattern attached to the X chromosome. Mutations related to the gene of filamina A, which is responsible for the synthesis of collagen, are responsible for the clinical and phenotypic manifestations of the disease, with predominantly female involvement. Rickets are caused by inadequate mineralization of the bone, which precedes the closure of the epiphy...

GH secreting adenomas could be associated with clinical acromegaly with or without hyperprolactinemia, being rare cases of non functioning adenomas. They correspond a 25–30%of pituitary adenomas, generaly presented as macroadenoma.Frequently, they have another hormones production, often prolactin and TSH. Almost 75% of cases are macroadenomas. A 48-year-old Caucasian patient admitted complaining of facial craniofacial alterations, polyarthralgia, holocranial headache and ...

Thyroid hypophyseal adenomas correspond to about 0.5 to 1% of pituitary adenomas. Tumor hypersecretion of TSH may also be present in plurihormonal adenomas that simultaneously secrete growth hormone and/or prolactin or FSH and LH glycoprotein hormones. A 37-year-old patient complaining of ears, hands, feet and face growth for 1 year. He reported amenorrhea for 04 years, sweating and joint pains. Associated comorbidities: Systemic arterial hypertension for 4 years in the use of...

Mice with isolated GH deficiency (IGHD) due to GHRH receptor mutations live longer than their normal siblings with an extended healthspan, i.e., the period of life free from disabilities. Human IGHD individuals due to a mutation in the GHRH receptor gene from Itabaianinha, Brazil, has a normal lifespan with an extended healthspan (1). Our hypothesis is that their aging is accompanied by a delayed cognitive decline. Accordingly, we used the Literacy Independent Cognitive Assess...

Population aging has become a universal worldwide phenomenon. Developing countries (such as Portuguese-speaking countries, with a high rate of illiteracy) will see the greatest increase in the absolute number of elderly people, and dementia disorders will pose enormous challenges to public health in these countries. Although the decline in GH secretion with age has been associated with deleterious conditions of aging, our understanding is the opposite, that the decline in GH s...
