1. Qual propedêutica inicial diante de um paciente com nódulo tireoidiano?
Diante desses pacientes, a anamnese e exame físico detalhados devem ser realizados para buscar condições associadas a um maior risco de malignidade. Como propedêutica complementar, o TSH sérico deve ser solicitado na avaliação inicial do nódulo tireoidiano, principalmente para excluir a possibilidade de ele ser autônomo ou hipercaptante (Nível A

2. Peptide receptor radionuclide therapy (PRRT) in radioiodine-refractory thyroid cancer: A case report of significant response to lu177 DOTA-TATE treatment
SUMMARY A 59-year-old woman with follicular thyroid carcinoma underwent total thyroidectomy followed by radioiodine treatment. Following treatment, the whole-body scan did not show any abnormal radioiodine uptake. However, during the follow-up, the serum thyroglobulin (Tg) value increased without detectable thyroglobulin-antibodies. We performed a Ga-68 DOTA

3. Comparative study of reliability of inflammatory markers over 18-FDG−PET CT scan in monitoring skull base osteomyelitis
Resumo Introdução O endpoint do tratamento da osteomielite da base do crânio ainda é uma questão de debate. Um tratamento baseado apenas em sintomas é sujeito a altas taxas de recorrência. Por outro lado, embora sejam mais informativos, o uso dos exames de imagem tem sido cada vez mais restringido. Os marcadores inflamatórios como a proteína-C reat

4. Enhancing PSMA-uptake with androgen deprivation therapy – a new way to detect prostate cancer metastases?
ABSTRACT Purpose: 68Ga-PSMA PET/CT imaging is a promising modality for the staging of recurrent prostate cancer (PCa). Current evidence suggests limited diagnostic value of the 68Ga-PSMA PET/CT in PSA-levels ≤0.3ng/mL. Experimental data have demonstrated an increase in PSMA-expression in PCa metastases by androgen deprivation in vitro. The aim of the curr

6. Outcomes of patients with bone metastases from differentiated thyroid cancer
ABSTRACT Objective Bone metastases (BM) from differentiated thyroid cancer (DTC) are associated with poor survival rates. Due to the low frequency of this entity, we performed a multicentric retrospective study that aimed to evaluate the presentation, outcome and causes of death in this population. Subjects and methods We reviewed file records from 10 data

7. Clinical utility of 18F-FDG PET/CT in the follow-up of a large cohort of patients with high-risk differentiated thyroid carcinoma
ABSTRACT Objective To evaluate the clinical utility of 18F-FDG PET/CT in patients with high-risk DTC. Subjects and methods Single-center retrospective study with 74 patients with high-risk differentiated thyroid cancer (DTC), classified in 4 groups. Group 1: patients with positive sTg or TgAb, subdivided in Group 1A: negative RxWBS and no foci of metasta

8. Targeting personalized medicine in a non-Hodgkin lymphoma patient with 18F-FDG and 18F-choline PET/CT
Summary Early diagnosis and staging of non-Hodgkin lymphoma (NHL) is essential for therapeutic strategy decision. Positron emission tomography/computed tomography (PET/CT) with fluordeoxyglucose (FDG), a glucose analogue, labeled with fluor-18 (18F-FDG) has been used to evaluate staging, therapy response and prognosis in NHL patients. However, in some cases,

9. Is [F-18]-fluorodeoxyglucose FDG-PET/CT better than ct alone for the preoperative lymph node staging of muscle invasive bladder cancer?
ABSTRACT Objective: To evaluate whether the use of [F-18]-FDG-PET/CT can accurately predict pelvic lymph node metastasis in patients with muscle invasive TCC of the bladder undergoing radical cystectomy. Materials and Methods: Fifteen patients with muscle invasive bladder cancer had undergone FDG-PET/CT scan from the skull base to the mid-thighs after IV i

10. Robotic Salvage Lymph Node Dissection After Radical Prostatectomy
ABSTRACTIntroduction and objective:Radical prostatectomy is a first-line treatment for localized prostate cancer. However, in some cases, biochemical recurrence associated with imaging-detected nodal metastases may happen. Herein, we aim to present the surgical technique for salvage lymph node dissection after radical prostatectomy.Materials and Methods:A 70

11. Which is the best route of administration for cell therapy in experimental model of small-for size syndrome in rats?
PURPOSE: To evaluate which is the best route of administration for cell therapy in experimental rat model of small-for size syndrome. METHODS: A total of 40 rats underwent partial hepatectomy (70%) that induces the small-for-size syndrome and were divided into four groups of route administration: intravenous, intraperitoneal, enteral and tracheal. The small

12. Staging and neuroprogression in bipolar disorder: a systematic review of the literature
INTRODUCTION: The use of clinical staging models is emerging as a novel and useful paradigm for diagnosing severe mental disorders. The term "neuroprogression" has been used to define the pathological reorganization of the central nervous system along the course of severe mental disorders. In bipolar disorder (BD), neural substrate reactivity is changed by r
