Endocardite por Cândida Parapsilosis Após Correcção Total de Tetralogia de Fallot. Tratamento Médico-Cirúrgico

São apresentados três casos de endocardite por Cândida Parapsilosis que surgiram em crianças com idade entre os sete e os nove anos, após terem sido submetidas a correcção total de Tetralogia de Fallot. As três crianças foram reoperadas, tendo recebido previamente uma delas terapêutica médica com anfotericina B e duas exclusivamente com Ketoconazol oral. Após negativação das hemoculturas foi efectuada remoção cirúrgica das vegetações com substituição do patch septal de dacron. A terapêutica com Ketoconazol prosseguiu durante 24 meses, com follow-up de 30 a 42 meses, não se tendo verificado nem reinfecção nem efeitos secundários da terapêutica. A ecocardiografia bidimensional revelou-se um método eficaz no diagnóstico e seguimento a longo prazo. A terapêutica médico-cirúrgica combinada, com timing cirúrgico baseado em dados clínicos e laboratoriais foi fundamental para os bons resultados, estando as crianças actualmente curadas.

Melanoma and Satellite Blue Papule

The colors that are seen in dermoscopy depend on the anatomic level of the skin at which the chromophores are seen. Blue color can be found in a variety of melanocytic and nonmelanocytic lesions. An 89-year-old man presented with a 3-year history of a slow-growing, hyperpigmented patch located on the distal third of the right arm. Dermoscopy showed an atypical network, irregularly distributed globules, pigmented internal streaks and a milky-red area. Based on these findings a diagnosis of slow-growing malignant melanoma was made. Simultaneously, a well-defined blue papule was seen on the proximal third of the same arm. Dermoscopy disclosed a homogeneous blue pattern. After clinical and dermoscopic correlation our differential diagnosis for this blue lesion included cutaneous melanoma metastasis, blue nevus and foreign body reaction. The patient recalled its onset 75 years ago after a grenade explosion. We also discuss the blue lesion appearance under reflectance confocal microscopy and high-definition optical coherence tomography. Histopathological examination after excision of the hyperpigmented patch and blue papule revealed a melanoma in situ and a foreign body reaction, respectively. The diagnostic evaluation of a blue lesion should always rely on the integration of all data, especially clinical and dermoscopic features. Other non-invasive techniques, like reflectance confocal microscopy and high-definition optical coherence tomography can also be important aids for its differential diagnosis.

Provas Epicutâneas sob Imunossupressão Sistémica - Contra-Indicação Absoluta?

Introdução: As provas epicutâneas (PE) são o exame complementar de diagnóstico indicado para avaliação de suspeita de dermite de contacto alérgica. Idealmente, devem ser realizadas sem que o doente se encontre sob imunossupressores. Existem contudo situações clínicas em que tal não é possível, não havendo informação disponível acerca de como realizar e valorizar os resultados das PE nestes doentes. O objectivo do presente trabalho é rever a literatura no que concerne à realização de PE sob imunossupressão iatrogénica. Material e Métodos: Revisão da literatura relevante para o tema publicada até Janeiro de 2015 e indexada à Medline. Resultados: De acordo com o reportado na literatura, foram realizadas PE em 77 doentes sob corticóide sistémico, 78 doentes sob ciclosporina (CyA), 6 sob azatioprina, 10 sob metotrexato (MTX), 4 sob micofenolato de mofetil (MMF), 11 sob fármacos anti-factor de necrose tumoral e 7 sob fármaco anti-IL-12/23. Foram ainda descritos 15 casos de realização de PE sob associação de imunossupressores. Verificaram-se reacções positivas em todos os grupos. Conclusão: O tratamento concomitante com imunossupressores não deve ser uma contra-indicação para realização de PE, estando descritas reacções positivas em doentes sob prednisolona, azatioprina, CyA, MTX, MMF, infliximab, etanercept, adalimumab e ustecinumab. Os resultados negativos ou duvidosos devem, contudo, ser interpretados de forma cautelosa.

Impact of mobile app user acquisition on managerial decisions: Evidence from empirical experiment

In this research we conducted a mixed research, using qualitative and quantitative analysis to study the relationship and impact between mobile advertisement and mobile app user acquisition and the conclusions companies can derive from it. Data was gathered from management of mobile advertisement campaigns of a portfolio of three different mobile apps. We found that a number of implications can be extracted from this intersection, namely to product development, internationalisation and management of marketing budget. We propose further research on alternative app users sources, impact of revenue on apps and exploitation of product segments: wearable technology and Internet of Things.

The Environmental History of Cetaceans in Portugal: Ten Centuries of Whale and Dolphin Records

The history between cetaceans and humans is documented throughout time not only in reports, descriptions, and tales but also in legal documents, laws and regulations, and tithes. This wealth of information comes from the easy spotting and identification of individuals due to their large size, surface breathing, and conspicuous above water behaviour. This work is based on historical sources and accounts accounting for cetacean presence for the period between the 12th and 17th centuries, as well as scientific articles, newspapers, illustrations, maps, non-published scientific reports, and other grey literature from the 18th century onwards. Information on whale use in Portugal's mainland has been found since as early as the 12th century and has continued to be created throughout time. No certainty can be given for medieval and earlier events, but both scavenging of stranded whales or use of captured ones may have happened. There is an increasing number of accounts of sighted, stranded, used, or captured cetaceans throughout centuries which is clearly associated with a growing effort towards the study of these animals. Scientific Latin species denominations only started to be registered from the 18th century onwards, as a consequence of the evolution of natural sciences in Portugal and increasing interest from zoologists. After the 19th century, a larger number of observations were recorded, and from the 20th century to the present day, regular scientific records have been collected. Research on the environmental history of cetaceans in Portugal shows a several-centuries-old exploitation of whales and dolphins, as resources mainly for human consumption, followed in later centuries by descriptions of natural history documenting strandings and at sea encounters. Most cetaceans species currently thought to be present in Portuguese mainland waters were at some point historically recorded.

Do jogo de fortuna ou azar

Currently, gambling doesn’t have a strong social disapproval. However, the phenomenon of gambling raises several issues related to property protection, compulsive gambling, the youngest personality development, the State taxes and social development measures, which some authors believe to be the protected legal interest in the criminalization of illegal gambling exploitation. However, the authorization system, and because several of those interests, constitutionally protected, are also violated in the authorized gambling places, it appears that the legislator intended to define the legal interest as the order and public tranquility. The purpose of this study is to understand what is protected with the illegal gambling exploitation. This will involve defining the concept of exploitation and the concept of gambling. Still, we will try to know if there are situations without ethical and social resonance and what their consequences.

Tegumentary leishmaniasis in the State of Amazonas: what have we learned and what do we need?

This study evaluated the occurrence of American tegumentary leishmaniasis (ATL) in the State of Amazonas, Brazil, in the last 30 years with emphasis on the last 10 years (2001 to 2010). The disease was predominantly observed in males (76.2%), in the 21- to 30-year-old age group (26.6%) and in extractive workers (43.7%); 3.3% of the cases were the mucosal form. The endemic channel shows the disease seasonality, with a predominance of cases at the beginning and end of each year. The number of cases by municipality in the period of 2001-2010 shows the maintenance of the endemic in the localities where the highest numbers of cases have always been registered, namely, Manaus, Rio Preto da Eva, Itacoatiara and Presidente Figueiredo. The comparison of data from 2001 to 2005 and from 2006 to 2010 showed the emergence of this disease in municipalities that had been previously unaffected. In the last years, there has been a significant increase in the activities of control, diagnosis and treatment of leishmaniasis in the State of Amazonas. In conclusion, the historical series of ATL analyzed in this study suggests that the transmission foci remain and are even expanding, though without continuous transmission in the intra- or peridomicile settings. Moreover, the disease will persist in the Amazon while the factors associated with infection acquisition relative to forest exploitation continue to have economic appeal. There is a real expectation of wide variations in disease incidence that can be influenced by climate and economic aspects.
