Developmental Morphology of a Dimorphic Grass Inflorescence: The Brazilian Bamboo Eremitis (Poaceae)

Premise of research.The highly specialized grass inflorescence varies with respect to phyllotaxis, with the reproductive meristem forming primary lateral branches that are either spirally arranged or distichous. The Brazilian bamboo Eremitis is highly unusual in that it has a dimorphic inflorescence, typically composed of an apical gynecandrous whorl of both male and female spikelets and basal whorls of male spikelets. Although not closely related to them, Eremitis shares some structural similarities with some early-divergent grasses.Methodology.We use SEM and LM to describe the development of the reproductive structures of Eremitis to clarify our understanding of the highly specialized grass inflorescence and flower.Pivotal results.Developmental studies show that the inflorescence of Eremitis is actually partially whorled and partially distichous. The apical whorl is abortive. The female spikelet is not terminal on the axis, in contrast with the majority of grasses. All the male spikelets are distichously attached to the inflorescence axis and separated into groups. There is a hollow style with two vascular bundles.Conclusions.The strong morphological similarities between Eremitis and some early-divergent grasses are here supplemented by several anatomical similarities, perhaps due to a shared pollination syndrome.

Morphology of ileal and jejunal pouches used as rectal substitutes

PURPOSE: Our aim was to determine whether the mucosa of a canine jejunal pouch used as a rectal substitute after proctocolectomy retains its morphologic features better than the mucosa of a canine ileal pouch so used. METHODS: Among ten dogs that underwent proctocolectomy, five had a jejunal pouch-distal rectal anastomosis and five an ileal pouch-distal rectal anastomosis. After six months, the animals were killed, the intestinal pouches and portions of unaltered distal ileum were removed, and a blinded, mucosal morphometric analysis was performed. RESULTS: The mucosa of the jejunal pouches had an overall thickness (mean ± standard deviation, anterior and posterior walls, 1,300 ± 140 μm), villous height (286 ± 46 μm), and crypt depth (790 ± 77 μm) greater than that of the ileal pouches (920 ± 170, 208 ± 47, and 530 ± 130 μm, respectively; P < 0.05). Moreover, the mucosal thickness of the jejunal pouches was similar to that of the distal ileum proximal to the pouch (1,200 ± 200 μm; P > 0.05), whereas the mucosal thickness of the ileal pouch was thinner (P < 0.05). CONCLUSIONS: The jejunal mucosa retains its major morphometric features when the jejunum is used as a rectal substitute after proctocolectomy. In contrast, the ileal mucosa atrophies when the ileum is so used.

Pseudoaneurysm of the internal carotid artery presenting with massive (recurrent) epistaxes: a life-threatening complication of craniofacial trauma

Vascular lesions can be serious complications resulting of blunt or penetrating trauma(1,2). Internal carotid artery lesion is one of most serious and relatively frequent in all mechanisms of craniofacial trauma. Several clinical manifestations can occur as central neurologic and cranial nerves deficits as well as several degrees of bleeding (from mild symptomatic to fatal). Recurrent and massive epistaxis can occur after trauma due to pseudaoneurysms of the external and internal carotid artery (ICA)(3,4). Considering its life-threatening course, the assisting physician has a relatively narrow time to detect and treat these lesions.We present two cases of recurrent and massive epistaxis secondary to ICA pseudoaneurysm following blunt and perforating trauma. Evolution was fatal in the first case with delayed treatment and uneventfully in the second which was treated by occlusion of the pseudoaneurysm and ICA via endovascular intervention.

Evaluation of nasal obstruction in various sagittal skeletal deformity of jaws

Nasal obstruction (NO) is a common symptom present in 25% of the general population, which significantly interferes with the quality of life. The different facial profiles and malocclusion patterns could be associated with the degree of NO. In order to evaluate the nasal function in patients with different facial morphology patterns, the authors developed a prospective study in which 88 patients from a dentofacial deformities center were included. These patients were submitted to fibrorhinoscopy (Mashida, ENT PIII) with a 3.2-mm cannula under topical anesthesia to evaluate septal deviation, inferior and medium turbinates, and pharyngeal tonsils. The 88 patients included in the study were divided into 3 groups according to the classification of the facial profile, distributed as follows: 32 class I, 28 class II, and 28 class III; the data collected was statistically analyzed by analysis of variance and the results are shown. The patients included in this study presented similar prevalence of NO with the reduction of airway function efficiency. Although it was not a statistically different, the group II presented higher mean Nasal Obstruction Syndrome Evaluation scores.
