Takayasu Arteritis as a Secondary Cause of Arterial Hypertension

Abstract Takayasu arteritis (TA) is a rare type of vasculitis that affects mainly the aorta and its major branches. It is highly similar to giant cell arteritis (GCA), and differentiation between them may not be achieved even by histological examination. Arterial hypertension is typical of TA and is caused by stenosis of the renal arteries. Here we report the case of a 59-year-old woman, with a history of dyslipidemia and anemia, seen in the Internal Medicine department for resistant hypertension. Evaluation of secondary causes led to stenosis of the renal arteries. Assessment of target organ involvement was performed by computed tomography angiograph which revealed ectasia of the aortic arch and ascending aorta, tortuous course of the brachiocephalic trunk and the proximal portion of the right common carotid artery; positron-emission tomography which showed diffuse increased uptake in the ascending aorta, compatible with large vessels vasculitis. The patient was submitted to aortic valve replacement with a biological prosthesis combined with myocardial revascularization (Bentall-De Bono procedure). Aortic biopsy specimens showed anatomical and pathological features of GCA and TA. Due to persistently uncontrolled hypertension, prednisone 60 mg was initiated,with significant improvement in patient's condition.

Pancreaticopleural fistula: An insidious cause of pleural effusion -case report.

Pancreaticopleural fistulas (PPF) are a rare etiology of pleural effusions. We describe a case of a 61-year-old man, with left chest pain with six months of progression who presented with a large volume unilateral pleural effusion. A thoracentesis was performed, which showed a dark reddish fluid(exudate) and high content of pancreatic amylase. After that an abdominal computed tomography (CT)and magnetic resonance cholangiopancreatography (MRCP) was done, revealing fistulous pathways that originated in the pancreas. The patient was admitted for conservative and endoscopic treatment by Endoscopic Retrograde Cholangiopancreatography (ERCP) and a prosthesis was placed on a fistulous path. He was discharged without complications, with the resolution of the pleural effusion and fistula.The interest of this case lies in the rarity of the event and absence of symptoms of the probable primary event (acute pancreatitis). The possible iatrogenic association with several drugs of his usual medication makes it even more complex.

Ecthyma gangrenosum: A view of blood on the skin.

Cutaneous findings should be actively sought in suspected cases of sepsis, as some of them (such as ecthyma gangrenosum) may provide clues about the infectious agent involved and the patient's immunosuppression status.

Antibiotic Clinic: Two Years' Experience in Outpatient Parenteral Antimicrobial Therapy in a Portuguese Hospital.

INTRODUCTION: Outpatient antimicrobial therapy programs have been in place for more than four decades. They provide safe and effective treatment for a selected group of patients while reducing costs. In Europe in general, and in Portugal in particular, these programs are still a relatively new phenomenon. The aim of this study is to describe our center's two years' experience with such a program (Antibiotic Clinic). MATERIAL AND METHODS: The cohort of treatments administered by the Antibiotic Clinic in its first two years of existence (September 12th 2016 to September 11th 2018) was analyzed and data pertaining to patients, infections, infectious agents, antimicrobials and outcomes (infection resolution, adverse events and death) were characterized. RESULTS: The Antibiotic Clinic treated 231 patients in 250 episodes, providing a total of 2357 days of antibiotic treatment. The urinary tract was the most common site (39.2%) and Enterobacteriaceae the most common agents (63.7% of isolates). Infections were resolved in 90.8% of treatments (95.6% of patients), adverse events were few (1.2%) and direct mortality was not found. The dropout rate was 1.6%. DISCUSSION: Infection resolution and adverse event rates were comparable to other centers. High treatment and low dropout rates point to high physician and patient acceptance. CONCLUSION: Our experience with this program suggests it is a safe and effective alternative to inpatient admission. This is in line with current literature which suggests efforts should be made to expand this treatment modality.

Introdução: Os programas de administração de antimicrobianos parentéricos em ambulatório (outpatient parenteral antimicrobial therapy) iniciaram-se há mais de quatro décadas. Para além de proporcionarem tratamento seguro e eficaz num grupo selecionado de doentes, permitem também a redução de custos. Na Europa, e em particular em Portugal, a implementação destes programas é um fenómeno recente. O objetivo deste estudo é descrever dois anos de experiência de Clínica do Antibiótico. Material e Métodos: Foram incluídos todos os doentes tratados na Clínica do Antibiótico nos dois primeiros anos de existência (12 de setembro de 2016 a 11 de setembro de 2018), sendo descritas variáveis relativas à população, infeções, agentes infeciosos, tratamentos e outcomes (resolução de infeção, eventos adversos e morte). Resultados: A Clínica do Antibiótico tratou 231 doentes em 250 episódios, garantindo 2357 dias de antibioterapia. O local de infeção mais comum foi o trato urinário (39,2%) e os agentes mais comuns foram as Enterobacteriaceae (63,7% dos isolamentos). Obteve-se resolução da infeção em 90,8% dos tratamentos (95,6% dos doentes), ocorreram poucos eventos adversos (1,2%) e a mortalidade direta foi nula. Houve uma taxa de abandono de 1,6%. Discussão: As taxas de resolução e de complicações foram comparáveis às de outros centros. Elevado número de tratamentos e baixa taxa de abandono apontam para boa aceitação por médicos e doentes. Conclusão: A nossa experiência sugere ser uma alternativa eficaz e segura ao tratamento em internamento. Estes resultados estão de acordo com a literatura, sugerindo que esforços deverão ser feitos para expandir a utilização destes programas.
