    Rey, E; Mearin, F; Alcedo, J; Ciriza, C; Delgado-Aros, S; Freitas, T; Mascarenhas, M; Mínguez, M; Santos, J; Serra, J
    INTRODUCTION: Irritable bowel syndrome (IBS) is a functional bowel disorder characterized by chronic or recurrent abdominal pain in association with defecation or a change in bowel habits. A predominant disorder of bowel habits, IBS is classified into three main subtypes: constipation-predominant IBS (IBS-C), diarrhea-predominant IBS (IBS-D) and IBS alternating between constipation and diarrhea (IBS-M). Linaclotide is a first-in-class, oral, once-daily guanylate cyclase-C receptor agonist (GC-CA) that is licensed for the symptomatic treatment of moderate-to-severe IBS-C in adults. This review aims to facilitate and optimize clinical practices, establishing common guidelines to monitor patients with IBS-C that are treated with linaclotide. METHODS: A group of...

  2. Patterns of Default Mode Network Deactivation in Obsessive Compulsive Disorder

    Gonçalves, ÓF; Soares, JM; Carvalho, S; Leite, J; Ganho-Ávila, A; Fernandes-Gonçalves, A; Pocinho, F; Carracedo, A; Sampaio, A
    The objective of the present study was to research the patterns of Default Mode Network (DMN) deactivation in Obsessive Compulsive Disorder (OCD) in the transition between a resting and a non-rest emotional condition. Twenty-seven participants, 15 diagnosed with OCD and 12 healthy controls (HC), underwent a functional neuroimaging paradigm in which DMN brain activation in a resting condition was contrasted with activity during a non-rest condition consisting in the presentation of emotionally pleasant and unpleasant images. Results showed that HC, when compared with OCD, had a significant deactivation in two anterior nodes of the DMN (medial frontal and superior frontal)...

  4. Hemolysis, Elevated Liver Enzymes, Low Platelets Syndrome Superimposed on Hemolytic Uremic Syndrome

    Martins, I; Conceição, MG; Gomes, PP; Clode, N
    A pregnancy complicated by typical hemolytic uremic syndrome (HUS) and hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome is reported. At 20 weeks of gestation, a case of HUS was diagnosed, with Shiga toxin-producing Escherichia coli identified. Plasmapheresis allowed continuation of the pregnancy for 5 weeks. Superimposed preeclampsia and HELLP syndrome were diagnosed after the establishment of nephrotic range proteinuria, hypertension and recurrence of hemolysis. This is a singular case, as it demonstrates that HELLP syndrome can superimpose upon HUS, a fact that can impact future research on reproductive immunology. It also reminds clinicians that the overlapping of clinical and...

  5. Intermediate osteotomies in rhinoplasty: a new perspective

    Pereira Nunes, D; Tinoco, C; Oliveira E Carmo, D; Paço, J
    The nasal dorsum framework plays a major role in nasal and facial harmony. This study presents a new approach to an already known technique, intermediate osteotomies, which can be used routinely in patients with cosmetically unpleasant changes in eyebrow-tip line features, allowing the acquisition of a natural, aesthetically agreeable and harmonious dorsum contour, while preserving nasal function. The approach was evaluated retrospectively in 50 consecutive patients at a tertiary referral hospital. Patients were asked to complete a survey to rate their satisfaction with the cosmetic outcome on a 5-point visual analog scale (VAS) and to compare the impact of nasal...

  6. Rubella in Sub-Saharan Africa and sensorineural hearing loss: a case control study

    Caroça, C; Vicente, V; Campelo, P; Chasqueira, M; Caria, H; Silva, S; Paixão, P; Paço, J
    Rubella infection can affect several organs and cause birth defects that are responsible for congenital rubella syndrome (CRS). Congenital hearing loss is the most common symptom of this syndrome, occurring in approximately 60% of CRS cases. Worldwide, over 100 000 babies are born with CRS every year. There is no specific treatment for rubella, but the disease is preventable by vaccination. Since 1969, the rubella vaccine has been implemented in many countries, but in Africa, only a few countries routinely immunize against rubella. The aim of this study was to estimate the rate of infection from the wild-type rubella virus...

  7. Asthma costs and social impact

    Nunes, C; Pereira, AM; Morais-Almeida, M
    In recent decades, both asthma prevalence and incidence have been increasing worldwide, not only due to the genetic background, but mainly because of the effect of a wide number of environmental and lifestyle risk factors. In many countries noncommunicable diseases, like asthma, are not yet considered a healthcare priority. This review will analyze and discuss disparities in asthma management in several countries and regions, such as access to healthcare human resources and medications, due to limited financial capacity to develop strategies to control and prevent this chronic disease. This review tries to explore the social and economic burden of asthma...

  9. Asthma-chronic obstructive pulmonary disease overlap syndrome - Literature review and contributions towards a Portuguese consensus

    Araújo, D; Padrão, E; Morais-Almeida, M; Cardoso, J; Pavão, F; Leite, R B; Caldas, A C; Marques, A
    Phenotypic overlap between the two main chronic airway pulmonary diseases, asthma and chronic obstructive pulmonary disease (COPD), has been the subject of debate for decades, and recently the nomenclature of asthma-COPD overlap syndrome (ACOS) was adopted for this condition. The definition of this entity in the literature is, however, very heterogeneous, it is therefore important to define how it applies to Portugal.

    Linhares, D; Neves, N; Ribeiro da Silva, M; Almeida Fonseca, J
    Traumatic fractures of the thoracic and lumbar spine are common causes of spine surgery. Pedicle screw fixation is usually chosen, using monosegmentar, short or long segment instrumentations, with or without bone graft. This review aims to evaluate the effect of transpedicular fixation in traumatic fractures of the thoracic and lumbar spine. A systematic search on controlled, randomized or quasi-randomized trials comparing different methods of surgical treatment of this fractures was performed, followed by a process of article selection, data extraction and bias assessment by 3 independent authors. Eight articles were included in a total of 5 comparisons, between different transpedicular...

  15. Serotype 3 Remains the Leading Cause of Invasive Pneumococcal Disease in Adults in Portugal (2012-2014) Despite Continued Reductions in Other 13-Valent Conjugate Vaccine Serotypes

    Horácio, AN; Silva-Costa, C; Lopes, JP; Ramirez, M; Melo-Cristino, J
    Since 2010 the 13-valent pneumococcal conjugate vaccine (PCV13) replaced the 7-valent vaccine (PCV7) as the leading pneumococcal vaccine used in children through the private sector. Although, neither of the PCVs were used significantly in adults, changes in adult invasive pneumococcal disease (IPD) were expected due to herd protection. We characterized n = 1163 isolates recovered from IPD in adults in 2012-2014 with the goal of documenting possible changes in serotype prevalence and antimicrobial resistance. Among the 54 different serotypes detected, the most frequent, accounting for half of all IPD, were serotypes: 3 (14%), 8 (11%), 19A (7%), 22F (7%), 14...

  16. Roles of interleukin-17 in uveitis

    Guedes, MC; Borrego, LM; Proença, RD
    Th17 cells, a CD4+ T-cell subset, produce interleukin (IL)-17, a pro-inflammatory cytokine that has been shown to be involved in several forms of infectious and noninfectious uveitis. Here, we explore the roles of this IL in uveitic disorders as well as in experimental autoimmune uveitis, the possible pathogenic implications of several cytokines associated with IL-17 and analyze the current outcomes and goals for drugs aiming for the IL-17 pathway.
