Malignant lentigo melanoma in patient with agressive thyroid folicular carcinoma

Leite Luciana Pedral S D , Pithon Ricardo B , Oliveira Nathalie S , Roriz Renata B , Silva Bruna L

Lentigo malign melanoma corresponds to the main histological type of melanomas ‘in situ’, particularly affecting Caucasian elderly exposed chronically to the ultraviolet rays. The therapeutic course should be surgical, with careful resection of the tumor, allowing free and wide margins. Follicular thyroid carcinoma corresponds to the second most common histological type characterized as a well differentiated neoplasm. It presents markedly vascular dissemination, bein...

Neuroendocrine neoplasia and obesity

Nunes Adriana , Medeiros Gertrudes M , Velloso Renata N , Gurjao Edmar C , Nunes Adriana B , Barbosa Paulo E S

Neuroendocrine neoplasia (NENs) are rare tumours that show features of neuroendocrine differentiation. Generally, NENs can be subdivides into high-grade neuroendocrine carcinomas (NECs) and low-to-intermediate grade neuroendocrine tumours (NETs). The most common Endodermal NETs’ localisations are the lungs, ileum, appendix, and rectum. Neuroectodermal NETs include medullary thyroid cancer (MTC), pheochromocytoma (PHEO), and paraganglioma (PGL). Nets are estimated to occur...

The impact of clomiphene citrate as add-on therapy in male acromegalic patients non-responsive to combined medical therapy

Vilar Lucio , Vilar Clarice , Albuquerque Luciano , Trovao Erik , The Ana Carolina , Gadelha Patricia , Campos Renata , Cardoso Izabela , Borges Thaise , Lyra Ruy

Introduction: Clomiphene citrate (CC), a selective estrogen receptor modulator that increases LH and FSH secretion, improves hypogonadism and fertility outcomes. Moreover, there is limited evidence that it may also be helpful as add-on therapy to normalize IGF-1 levels in male acromegalic patients.Objective: To assess the effect impact of CC on serum IGF-1 and testosterone levels in male acromegalic patients not controlled by the combination of lanreotid...

Molecular variability determines subtle adrenal biosynthetic defect in non-classical congenital adrenal hyperplasia due to 21-hydroxylase deficiency

Mermejo Livia , Coeli-Lacchini Fernanda , Turatti Wendy , Elamid Marcia , Parente Renata , Martinelli Carlos , Antonini Sonir , Castro Margaret , Moreira Ayrton

There is a clinical spectrum of non-classical congenital adrenal hyperplasia due to 21-hydroxylase deficiency (NC-CAH). In addition, CYP21A2 gene mutations analysis present in homozygosis or as compound heterozygosis.Objectives: To evaluate the relationship between the genotype and biochemical profiles and also compare with clinical severity in NC-CAH.Patients and methods: Clinical, hormonal and molecular data of 57 patien...

Improved xanthomas after leptin replacement short therapy in congenital lipodystrophy patient

Oliveira-Filho Antonio F , Dantas Irla A , Velloso Renata N , de Oliveira Sofia N P , Candido Diego F F , Nunes Adriana

Berardinelli-Seip syndrome is an autosomal recessive disorder characterized by generalized lipoatrophy, extreme insulin resistance with dyslipidaemia in childhood and development of diabetes and hepatic steatosis in adolescence. The metabolic derangements can be severe and lead to substantial comorbidities, including acute pancreatitis, hepatic cirrhosis, and premature cardiovascular disease. Other manifestations can include polycystic ovarian syndrome, acanthosis nigricans, a...

Pituitary insufficiency following traumatic thoracic injury in adolescent male patient-case study

Gilis-Januszewska Aleksandra , Wilusz Malgorzata , Turek-Jabrocka Renata , Pantoflinski Jacek , Trofimiuk-Muldner Malgorzata , Kluczynski Lukasz , Hubalewska-Dydejczyk Alicja , Pach Dorota

Traumatic thoracic injuries in children and adolescents are rare, but could be connected with others traumas, often with traumatic brain injury (TBI). Based on data in the current literature, approximately 15–20% of TBI patients develop chronic hypopituitarism. Growth hormone (GH) and ACTH deficiency are the most common, followed by gonadotropins and thyroid-stimulating hormone. The greatest challenge associated with endocrine complications in individuals with polytrauma ...

Temozolomide treatment in pituitary tumor causing Cushing’s Disease resistant to conventional therapy – case report

Gilis-Januszewska Aleksandra , Pantoflinski Jacek , Turek-Jabrocka Renata , Sokolowski Grzegorz , Wilusz Malgorzata , Pach Dorota , Hubalewska-Dydejczyk Alicja

Objective: The management of pituitary tumors causing Cushing’s Disease are a multidisciplinary challenge to clinicians with neurosurgery as a first line treatment followed by the radiotherapy and pharmacotherapy including chemiotherapy.Such tumors are difficult to treat with high rate of recurrence. To date only 25 patients with Cushing Disease treated with the new alkylating agent temozolamide (TMZ) have been reported.Materials and methods: Sixty-...

Combined therapy PRRT with long acting somatostatin analogue: results of 7 years’ experience

Sowa-Staszczak Anna , Stefanska Agnieszka , Buziak-Bereza Monika , Trofimiuk-Muldner Malgorzata , Mikolajczak Renata , Tomaszuk Monika , Hubalewska-Dydejczyk Alicja

Introduction: The aim of this study was to assess the survival rate of patients with disseminated or inoperable neuroendocrine tumors (NETs) after PRRT with the use of 90Y-DOTATATE combined with long acting somatostatin analogue.Materials and methods: 72 patients were treated with PRRT in our Department. The 90Y-DOTATATE therapeutic activity was calculated per total body surface area up to a total of 7.4 GBq/m2 administra...

Impact of different methods on the detection frequency of BRAF mutation in papillary thyroid carcinoma

Kowalik Artur , Kowalska Aldona , Kopczynski Janusz , Walczyk Agnieszka , Nowak Ewelina , Wypiorkiewicz Elzbieta , Chodurska Renata , Pieciak Liliana , Gozdz Stanislaw

Introduction: Still there is a discussion about the importance of diagnostic and prognostic relevance BRAFV600E mutation. The wide range of BRAFV600E mutation frequency (40–80%) doesn’t facilitate this task. Population diversity and genotyping methodology are suspected sources of differences seen in the mutation frequencies detected by different studies. The aim of this study was to assess the prevalence BRAF V600...

Occurrence other than V600E mutation in the BRAF gene in papillary thyroid carcinoma

Kowalik Artur , Kowalska Aldona , Kopczynski Janusz , Walczyk Agnieszka , Nowak Ewelina , Wypiorkiewicz Elzbieta , Chodurska Renata , Pieciak Liliana , Gozdz Stanislaw

Introduction: BRAFV600E mutation constitutes 98–99% of all detected mutation in thyroid carcinoma. The remaining 2% are BRAF mutations detected in the vicinity of codon V600. Due to the low incidence not much is known about their importance for the development of papillary thyroid carcinoma (PTC). In addition, some of these mutations co-occur with the mutation BRAFV600E.Methods/design: The study prese...
