- Neonatal Appendicitis – an Uncommon Diagnosis, not to be ForgottenPublication . Gil, AT; Morais, S; Faria, DAcute appendicitis is a common disease in older children, but extremely rare in the neonate. Nevertheless, the true incidence might be underestimated, given the difficulty of the diagnosis. Subtle clinical signs and symptoms usually result in high morbidity and mortality due to delayed diagnosis and surgical intervention. The presentation of neonatal appendicitis can be identical to necrotizing enterocolitis, leading to misdiagnosis. Appendicitis should therefore be considered in the differential diagnosis for necrotizing enterocolitis and needs strong clinical suspicion. We report a case of a premature newborn who presented with vomiting, abdominal distension and free intra-peritoneal air on plain x-ray. He was initially diagnosed and treated as necrotizing enterocolitis, but the absence of clinical improvement with standard treatment led to exploratory laparotomy. Surgical exploration revealed an acutely inflamed appendix with normal small and large intestines and appendectomy was performed. The post-operatory period was uneventful and the infant was discharged home. Follow-up confirmed a normal growth and neurodevelopment. We herein report this case in order to raise awareness to this unusual pathology, so that an early diagnosis and treatment can lead to a better outcome, improving survival rate and reducing long term morbidity. We believe uncommon pathologies, like neonatal appendicitis, should be reported to facilitate proper epidemiologic studies.

- Brain activation of the defensive and appetitive survival systems in obsessive compulsive disorderPublication . Gonçalves, OF; Soares, JM; Carvalho, S; Leite, J; Ganho, A; Fernandes-Gonçalves, A; Frank, B; Pocinho, F; Relvas, J; Carracedo, A; Sampaio, ASeveral studies have shown that basic emotions are responsible for a significant enhancement of early visual processes and increased activation in visual processing brain regions. It may be possible that the cognitive uncertainty and repeated behavioral checking evident in Obsessive Compulsive Disorder (OCD) is due to the existence of abnormalities in basic survival circuits, particularly those associated with the visual processing of the physical characteristics of emotional-laden stimuli. The objective of the present study was to test if patients with OCD show evidence of altered basic survival circuits, particularly those associated with the visual processing of the physical characteristics of emotional stimuli. Fifteen patients with OCD and 12 healthy controls underwent functional magnetic resonance imaging acquisition while being exposed to emotional pictures, with different levels of arousal, intended to trigger the defensive and appetitive basic survival circuits. Overall, the present results seem to indicate dissociation in the activity of the defense and appetitive survival systems in OCD. Results suggest that the clinical group reacts to basic threat with a strong activation of the defensive system mobilizing widespread brain networks (i.e., frontal, temporal, occipital-parietal, and subcortical nucleus) and blocking the activation of the appetitive system when facing positive emotional triggers from the initial stages of visual processing (i.e., superior occipital gyrus).

- Cardiovascular magnetic resonance imaging assessment of diastolic dysfunction in a population without heart disease: a gender-based studyPublication . Graça, B; Ferreira, MJ; Donato, P; Castelo-Branco, M; Caseiro-Alves, FOBJECTIVES: Asymptomatic left ventricular (LV) diastolic dysfunction is increasingly recognised as an important diagnosis. Our goal was to study the prevalence and gender differences in subclinical LV diastolic dysfunction, using cardiovascular magnetic resonance imaging (CMR) at 3 T. METHODS: We prospectively studied 48 volunteers (19 male and 29 female, mean age 49 ± 7 years) with no evidence of cardiovascular disease. We used CMR to measure left atrium (LA) and LV volumes, LV peak filling rate and transmitral flow. RESULTS: The overall prevalence of LV diastolic dysfunction in our cohort varied between 20 % (based on evaluation of LV filing profiles) and 24 % (based on the evaluation of the transmitral flow). The prevalence of diastolic dysfunction was higher in men than in women, independently of the criteria used (P between 0.004 and 0.022). Indexed LV end-diastolic volume, indexed LV stroke volume, indexed LV mass, indexed LA minimum volume and indexed LA maximum volume were significantly greater in men than in women (P < 0.05). All the subjects had LV ejection fractions within the normal range. CONCLUSIONS: It is clinically feasible to study diastolic flow and LV filling with CMR. CMR detected diastolic dysfunction in asymptomatic men and women. KEY POINTS: • CMR imaging offers new possibilities in assessing left ventricular diastolic function. • The prevalence of diastolic dysfunction is higher in men than in women. • The prevalence of some diastolic dysfunction in a normal population is 24 %.
- Infecção periprotética da anca e joelho: algumas recomendaçõesPublication . Bahute, A; Gaspar, R; Judas, FA infecção periprotética representa uma das complicações mais graves da cirurgia reconstrutiva ortopédica. Estima-se que a incidência da infecção periprotética seja de 1% em artroplastias primárias da anca, de 2% em artroplastias primárias do joelho e de 5% nas artroplastias de revisão da anca e joelho. O objectivo central deste trabalho foi apresentar algumas das recomendações mais importantes no âmbito da prevenção, diagnóstico e tratamento da infecção periprotética de acordo com uma revisão bibliográfica actual da literatura ortopédica internacional. Na falta de evidência científica inequívoca as recomendações aqui descritas não são, por isso, vinculativas. Todavia, são de importância capital na condição de linha orientadora para a abordagem da infecção periprotética, sendo certo que são necessários mais estudos com um maior tempo de recuo para se chegar a conclusões mais consistentes.
