Parathyroid carcinoma: case report

O carcinoma de paratireoide (CP) constitui entidade patológica incomum e detentora de peculiaridades propedêutico-terapêuticas. Em geral, apresenta-se como hiperparatireoidismo primário sintomático, no qual corresponde a somente 1% nesse subgrupo. O diagnóstico de CP é difícil, tanto clínico quanto histológico, devido à inconstância de critérios. Laboratorialmente, é comum apresentar hipercalcemia e PTH bastante acima do valor de referência. A cirurgia é o único tratamento curativo e efetivo para o carcinoma de paratireoide. Relato de caso: Paciente M.P.R.L., 48 anos, sexo feminino, melanodérmica, natural e procedente de Felisburgo – MG. Evoluíra há 02 anos com fraqueza progressiva, anemia, disfunção renal, dores crônicas e perda ponderal (cerca de 15 kg nos últimos cinco meses), associada a hipercalcemia PTH-dependente e declínio da função renal. Estudo ultrassonográfico (USG) de região cervical demonstrou presença de dois nódulos tireoideanos e cintilografia de paratireoides sem evidências de hiperplasia ou adenoma das glândulas. Foi admitida no Hospital Santa Casa de Belo Horizonte para seguimento propedêutico e terapêutico do quadro apresentado.Parathyroid carcinoma (PC) is an uncommon pathology which has propaedeutic and therapeutic peculiarities. In general, it presents as symptomatic primary hyperparathyroidism, that corresponds to only 1% in this subgroup. Both the clinical and histological diagnosis of PC are difficult due to inconsistent criteria. Laboratorial exams commonly present hypercalcemia and PTH well-above the reference value. Surgery is the only curative and effective treatment for parathyroid carcinoma. Case report: Patient M.P.R.L., 48 years old, female, melanodermic, native and from Felisburgo - MG. The disease had been progressing for 2 years with progressive weakness, anemia, renal dysfunction, chronic pain and weight loss (about 15 kg in last five months), associated with PTH-dependent hypercalcemia and renal function decline. A cervical study showed the presence of two thyroid nodules whereas a parathyroid scintigraphy showed no evidence of glands hyperplasia or adenoma. She was admitted to the Santa Casa Hospital of Belo Horizonte for a propaedeutic and therapeutic management of the presented profile

NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions.
