ABSTRACT
Abstract A new species of Diolcogaster (Hymenoptera: Braconidae) is described and illustrated. Additionally, its position within the recently published key to New World species of the xanthaspis species-group (to which the described Diolcogaster belongs) is provided. The gregarious larval parasitoid Diolcogaster choi sp. nov. was collected in Maringá, Paraná State, Brazil. This natural enemy was recovered from a caterpillar of Hypercompe cunigunda (Stoll, 1781) (Lepidoptera: Erebidae) that was feeding on plant of passionflower, Passiflora edulis Sims (Passifloraceae). The fauna of the xanthaspis group in the New World now includes five species, including the new species from Brazil described in this paper. Diolcogaster choi sp. nov. differs anatomically, and is morphologically diagnosed, from all other known member of the xanthaspis group of the genus Diolcogaster, to which it belongs. The species also differs in recorded host, and its DNA barcode appears to be distinctive among described Diolcogaster.
ABSTRACT
ABSTRACT This is the first report of Cotesia scotti (Valerio and Whitfield) comb. nov. in Brazil, attacking larvae of the black armyworm, Spodoptera cosmioides, and the southern armyworm, S. eridania. The moth larvae were found respectively, infesting a protected cropping of organic tomato in Hidrolândia, Goiás, Brazil, and a transgenic soybean crop in São José dos Pinhais, Paraná, Brazil. Biological, molecular and morphological characters were used to confirm the identity of the specimens. Parasitoid identification presented a challenge since the species has most diagnostic characters of the genus Cotesia Cameron, but few in the poorly defined genus Parapanteles Ashmead. Based on morphological and molecular evidence, we transfer Parapanteles scotti to the genus Cotesia. The new combination is discussed by comparison with morphologically similar species and available molecular data.
ABSTRACT
ABSTRACT A new species of Diolcogaster (Ashmead, 1900) (Hymenoptera: Braconidae) is described and illustrated. Additionally, a key to all New World species formally published of the xanthaspis species-group (to which the new species belongs) is provided. The solitary larval parasitoid Diolcogaster flammeus sp. nov. was collected in Viçosa, Minas Gerais State, Brazil. This natural enemy was reared from caterpillars of Agaraea minuta (Schaus, 1892) (Lepidoptera: Erebidae) feeding on plants of spiked spiralflag ginger, Costus spicatus (Jacq.) Sw. and ginger spiral, Costus spiralis (Jacq.) Roscoe var. spiralis (Costaceae). The fauna of the xanthaspis group in the New World included just three published species prior to this publication. Diolcogaster flammeus sp. nov. is the only yellow-orange species of the xanthaspis group recorded in the New World thus far.
ABSTRACT
Las espóndilo artropatías (spa) son un grupo de condiciones inflamatorias crónicas, frecuentes y eventualmente discapacitantes. Son una familia de desórdenes interrelacionados, pero heterogéneos con diferentes manifestaciones clínicas. La espondilitis anquilosante (EA) es el prototipo de este grupo de patologías, caracterizadas por un compromiso articular axial y/o periférico, entesitis, ciertas manifestaciones extra-articulares características y una fuerte asociación genética con el HLA - B27. La afectación de otros miembros de la familia del paciente es otra característica importante. La espondilitis o espóndilo artritis anquilosante es un reumatismo inflamatorio crónico que afecta de forma predominante al esqueleto axial, pelvis, columna vertebral y tórax, en especial a las articulaciones sacroilíacas, su localización más constante y característica. También puede afectar a las articulaciones periféricas y algunos pacientes desarrollan manifestaciones extraarticulares. Los varones se afectan con mayor frecuencia que las mujeres en una proporción de 3-4:1. Su prevalencia varía en función de la frecuencia del antígeno HLA-B27 en la población analizada. La frecuencia más alta se ha encontrado en ciertas tribus de indios americanos, en especial los Haida, donde un 50% de la población general posee el HLA-B27. En la raza blanca se estima una prevalencia de 2 a 10 casos por 1.000 habitantes; esta cifra es inferior en las razas negra y oriental. A continuación se presenta el caso de una mujer de 50 años con lumbalgia crónica y diagnosticada como E.A.
The spondyloarthropathies (spa) are a group of frequent chronic inflammatory conditions eventually disabling. They are a family of interrelated disorders, but they are heterogeneous with different clinical manifestations. Ankylosing spondylitis (AS) is the prototype of this group of diseases characterized by an axial and / or peripheral joint involvement, enthesitis, certain extra-articular manifestations and a strong genetic association with HLA - B27. The involvement of other relatives of patients is another important feature. Spondylitis or spondylo arthritis ankylosing, is a chronic inflammatory rheumatism which affects mainly the axial skeleton, pelvis, spine and thorax, especially the sacroiliac joints, its most frequent and characteristic location. It can also affect the peripheral joints and some patients develop extra-articular manifestations. Males are affected more often than females by a ratio of 3-4:1. Its prevalence varies depending on the frequency of HLA-B27 antigen in the population tested. The highest frequency has been found in certain American Indian tribes, especially the Haida Indians, where 50% of the general population has the HLA-B27. In Caucasians prevalence of 2 to 10 cases per 1,000 inhabitants is estimated; this figure is lower in black and oriental races. Here is the case of a 50 year old woman with chronic low back pain and diagnosed as AS.

La estenosis esofágica congénita es una entidad rara de causa no conocida, que requiere alto índice de sospecha para su diagnóstico y tratamiento adecuado. Se presenta caso de niña de 1,2 años de edad con estenosis esofágica congénita causada por hipertrofia fibromuscular. Manejada con dilataciones sin éxito por lo que requirió resección segmentaria. Se discuten las dificultades diagnósticas y terapéuticas.
