The mammals of Angola
Scientific investigations on the mammals of Angola started over 150 years
ago, but information remains scarce and scattered, with only one recent published
account. Here we provide a synthesis of the mammals of Angola based on a thorough
survey of primary and grey literature, as well as recent unpublished records. We present
a short history of mammal research, and provide brief information on each species
known to occur in the country. Particular attention is given to endemic and near endemic
species. We also provide a zoogeographic outline and information on the conservation
of Angolan mammals. We found confirmed records for 291 native species, most of
which from the orders Rodentia (85), Chiroptera (73), Carnivora (39), and
Cetartiodactyla (33). There is a large number of endemic and near endemic species,
most of which are rodents or bats. The large diversity of species is favoured by the wide range of habitats with contrasting environmental conditions, while endemism tends to
be associated with unique physiographic settings such as the Angolan Escarpment. The
mammal fauna of Angola includes 2 Critically Endangered, 2 Endangered, 11
Vulnerable, and 14 Near-Threatened species at the global scale. There are also 12 data
deficient species, most of which are endemics or near endemics to the countryinfo:eu-repo/semantics/publishedVersio

Neurotrophilic Dermatosis of the Dorsal Hand - Report of Two Patients
O conceito de dermatoses neutrofĂlicas engloba diversas entidades que partilham aspetos clĂnicos e histolĂłgicos. Recentemente descrita, a dermatose neutrofĂlica do dorso das mĂŁos Ă© uma patologia com etiologia desconhecida que se assemelha, clinicamente, a uma variante localizada da SĂndrome de Sweet com lesĂ”es predominantemente localizadas no dorso das mĂŁos e com presença variĂĄvel de sintomas gerais acompanhantes. Do ponto de vista histolĂłgico Ă© caracterizada por um denso infiltrado inflamatĂłrio neutrofĂlico, sendo variĂĄvel a existĂȘncia de achados de vasculite.
Os autores apresentam dois doentes com dermatose neutrofĂlica do dorso das mĂŁos e discutem os aspetos clĂnicos,
laboratoriais, histopatolĂłgicos e a as opçÔes terapĂȘuticas desta entidade.
A dermatose neutrofĂlica do dorso das mĂŁos Ă© um conceito em evolução, que partilha diversos aspetos comuns com outras dermatoses neutrofĂlicas, sugerindo um espetro continuo deste grupo de doenças
