RESUMEN

PURPOSE: Approximately 45% of anaplastic thyroid cancer (ATC) patients harbor a BRAFV600E mutation and are eligible for target therapy (TT) with BRAF and MEK inhibitors (BRAFi/MEKi), nevertheless, few data advocate for this. Hence, we've conducted a systematic review and meta-analysis investigating the effectiveness and safety of BRAFi/MEKi in BRAFV600E ATC patients. METHODS: PubMed, Embase, and the Cochrane Library were systematically searched for BRAFi/MEKi TT in BRAFV600E ATC patients. Outcomes included objective response rate (ORR), disease control rate (DCR), overall survival (OS), progression-free survival (PFS), duration of response (DOR) and adverse events (AEs). RESULTS: Nine studies with 168 patients were included. Median follow-up ranged from 2.0 to 47.9 months. 75% of patients had stage IVc. In a pooled analysis, ORR was 68.15% (95% CI 55.31-80.99, I2 = 47%) and DCR was 85.39% (95% CI 78.10-92.68, I2 = 0), with a median DOR of 14.4 months (95% CI 4.6-14.4) and a median PFS of 6.7 months (95% CI 4.7-34.2). Moreover, 1-year OS rate was 64.97% (95% CI 48.76-81.17, I2 = 84%) and 2-years OS rate was 52.08% (95% CI 35.71-68.45, I2 = 79%). Subgroup analysis showed patients in the neoadjuvant setting had higher rates of 1 and 2-years OS and observational studies tended to report higher rates of ORR than clinical trials. No new or unexpected adverse events were found. CONCLUSIONS: Our study demonstrated BRAFi/MEKi have a decent activity for BRAFV600E ATC patients, especially in the neoadjuvant setting, with a tolerable safety profile. However, further clinical trials are warranted to investigate these findings.

RESUMEN

INTRODUCTION: The goiter, a neglected heterogeneous molecular disease, remains a major indication for thyroidectomies in its endemic regions. OBJECTIVES: This study analyzed differential gene expression in surgical specimens diagnosed with multi nodular and compared the data to that of thyroid tissue without multinodular goiter from patients undergoing thyroidectomy in Manaus-AM, Brazil using RNA-seq technology. METHODOLOGY: The transcriptome information of the surgical specimen fragments with and without multinodular goiter was accessed by Illumina HiSeq 2000 New Generation Sequencing (NGS) using the RNA-seq NEBNext® Ultra™ RNA Library Prep Kit for Illumina®-#E7530L protocol and differential gene expression analysis. RESULTS: Differences were found between the gene expression profiles of the diseased tissues and those of the healthy control tissues; at least 70 genes were differentially expressed. The HOTS gene was expressed only in multinodular goiter tissues (p < 0.05). CONCLUSION: These results demonstrate that the gene expression profile of multinodular goiter is pro-tumoral and that HOTS can play a central role in multinodular goiter development.

RESUMEN

O hiperaldosteronismo primário é causa de hipertensão arterialsecundária, com possibilidade de cura após cirurgia em 30a 75% dos casos. O objetivo deste estudo foi relatar um casode hipertensão arterial secundária a adenoma adrenal produtorde aldosterona. Paciente feminino, 35 anos, natural de Beruri(AM), procedente de Manaus, foi admitida com pressão arterialde 220x125mmHg associada a fraqueza muscular de membrosinferiores e câimbras. Na história patológica pregressa, havia orelato de hipertensão arterial diagnosticada há 2 anos, em tratamentocom três classes de anti-hipertensivos. Durante internaçãoem hospital geral, o quadro relatado associado à hipocalemiae alcalose metabólica sugeriram diagnóstico de hipertensão arterialsecundária a hiperaldosteronismo primário. Níveis elevadosde aldosterona plasmática, com renina suprimida e relação aldosterona-renina elevada, confirmaram o diagnóstico de hiperaldosteronismoprimário. A tomografia computadorizada deabdome evidenciou lesão tumoral com 2,3x2,0cm em glândulasuprarrenal esquerda sugestiva de adenoma adrenal. Pacientefoi submetida a adrenalectomia à esquerda com histopatologiacompatível com adenoma adrenal. Seis meses após a cirurgia,paciente evoluiu com normalização da calemia, porém mantevehipertensão arterial com necessidade de terapia anti-hipertensiva,sem novos picos hipertensivos. Se hiperaldosteronismo primáriodiagnosticado precocemente, há possibilidade de cura dahipertensão arterial secundária após adrenalectomia, reduzindo o efeito deletério da mesma sobre os sistemas cardiovascular, cerebrovasculare renal.(AU)

The primary hyperaldosteronism is a cause of secondaryhypertension, with the possibility of healing after surgery in 30to 75% of cases. The objective of this study was to report a caseof secondary hypertension to aldosterone-producing adrenaladenoma. A female patient, 35 years, from Beruri (AM), Brazil,who came to Manaus, was admitted into the emergency room withblood pressure of 220x125mmHg, associated with lower limbmuscle weakness and cramps. In the past medical history, there wasa report of hypertension diagnosed 2 years before, and she was undertreatment with three classes of antihypertensive drugs. Duringhospitalization in a general hospital, the case reported associatedto hypokalemia and metabolic alkalosis suggested a diagnosis ofhypertension secondary to primary hyperaldosteronism. Elevatedlevels of plasmatic aldosterone, suppressed renin and highaldosterone-renin relation suggested primary hyperaldosteronism.The abdominal computerized tomography scan revealed a tumor of2.3x2.0cm in the left adrenal gland, suggesting adrenal adenoma.Patient underwent left adrenalectomy and histopathology wascompatible to adrenal adenoma. After 6 months of surgery, thepatient experienced normalization of kalemia but kept arterialhypertension, requiring anti-hypertensive therapy, but had no othershypertensive peaks. Early diagnosis of primary hyperaldosteronismallowed the cure of hypertension after adrenalectomy, reducingdeleterious effects of high blood pressure levels on the cardiovascular,cerebrovascular and renal systems.(AU)

RESUMEN

A cândida sp. são fungos comensais dos seres humanos e consideradasflora normal do trato gastrointestinal e genitourinário.Entretanto alterações na imunidade do hospedeiro podem culminarem infecção por estes fungos, definida como candidíase.Uma causa importante do desequilíbrio imunológico são asdoençasendócrinas, principalmente o Diabetes tipo 2. Pacientesdiabéticos estão mais propensos a desenvolver formas infecciosasde candidíase, destacando o comprometimento esofágicoque muitas vezes, não é diagnosticado. O objetivo deste estudofoi relatar um caso de paciente diabético tipo 2 com processoinfeccioso importante à esclarecer decorrente de extensa cândidíaseesofágica. Paciente masculino, 55 anos, procedente deItacoatiara-AM, tabagista de longa data. Após história prévia deinternação hospitalar para tratamento de Diabetes tipo 2 descompensadae piomiosite de coxa esquerda, evoluiu com asteniainsidiosa, anorexia, mal-estar e febre diária (38,5 ºC), intermitente,vespertina, sendo diagnosticado e tratado para infecçãodo trato urinário, sem melhora. Após piora do quadro, acrescidode disfagia para sólidos e perda ponderal, foi re-internado paraelucidaçãodiagnóstica. Durante a investigação apurou-se sangueoculto nas fezes positivo, seguida de endoscopia digestivaalta mostrando várias placas elevadas esbranquiçadas linearese confluentes ocupando todo o trajeto do esôfago, compatívelcom candidíase esofágica grau III de KODSI. As sorologias paraHIV e Hepatites B e C, foram negativas. A biopsia revelou esofagiteaguda erosiva. Devemos estar atentos à possibilidade de infecção por cândida, em especial, o comprometimento esofágico,nos pacientes diabéticos descompensados que apresentemfatores de risco associados a sinais e sintomas da doença e/ouinfecciosos, sem foco definido.(AU)

Candida sp. are commensal fungi of humans and are considerednormal flora of the gastrointestinal and genitourinary tracts.However, changes in the host immunity may lead to infection bythese fungi, defined as candidiasis. A major cause of the imbalanceare immune endocrine diseases, especially type 2 diabetesmellitus. Diabetic patients are more likely to develop infectiousforms of candidiasis, in particular the esophageal involvementthat often goes undiagnosed. The aim of this study was to reporta case of a type 2 diabetic patient with an infectious processwhich is important to clarify the result of extensive esophagealcandidiasis. Male patient, 55 years, coming from Itacoatiara-AM,a longtime smoker. After a history of hospitalization for treatmentof decompensated diabetes mellitus type 2 and pyomyositis of theleft thigh, it progressed with insidious asthenia, anorexia, malaiseand intermittent evening daily fever (38.5 °C), he was diagnosedand treated for urinary tract infection with no improvement.After the condition worsened, followed by dysphagia for solidsand weight loss, he was re-admitted for diagnosis. During theinvestigation it was found positive fecal occult blood, upperendoscopy showed multiple elevated confluent whitish linearplaques occupying the entire course of the esophagus, esophagealcandidiasis compatible with grade III KODSI. Serology forHIV and Hepatitis B and C were negative. The biopsy revealed acute erosive esophagitis. We must be alert to the possibility ofinfection by Candida, in particular, esophageal involvement inpatients presenting decompensated diabetic risk factors associatedwith signs and symptoms of disease and/or infections, without adefined focus.(AU)
