Objective: To evaluate the results of treating axillary hyperhidrosis by vacuum curettage. Methods: Vacuum curettage was performed in 37 patients to treat axillary hyperidrosis, from May 1999 to December 2005. Based on the reason for patients looking for treatment (interference in their quality of life), the evaluation criterion was a validated self- applicable questionnaire called \\

Some crotalid venoms have a hemagglutinant fraction with affinity to cell receptors. This can be used as an antiviral agent that blocks adsorption of the virus in the cell membrane. One of these fractions was isolated and its innocuity compared to the effect of complete venoms. A. piscivorus, A. contortix and C. scutulatus venoms were tested, with the first exhibiting

[True posttraumatic femoral artery aneurysm: a rare clinical entity].  

PubMed

Traumatic etiology in aneurysms is very rare. After arterial trauma we usually find pseudo aneurysms. True aneurysms are due to deterioration of the arterial wall in small and long-term repetitive trauma. Pseudo aneurysms are usually described on radial and cubital artery in patients who work with vibrating tools ("hypothenar and thenar hammer syndrome") and on axilar artery in those who use axilar crutches. We present a case of a woman with a true aneurysm of the femoral artery developed due to repetitive trauma of the femoral region at the work place. The patient presented as an emergency, with ruptured aneurysm and she underwent an emergency operation. The diagnosis was established late by histopathological examination. This is the first case of posttraumatic true aneurysm with this location. True aneurysms should be considered in repetitive trauma regardless of anatomical region. PMID:20201257

The incorporation of the nuclear medicine to the surgical current practice In the treatment of the cancer of breast, by means of the application of radioactive isotopes, have supposed a great achievement not only in the surgical and predicted results but also in the surgical skills more effective and less aggressive. The systematic research of the marking and extirpation of Sentinel Lymph Node is avoiding in the early cancer the linfadenectomy axilar. The application of the ROLL and SNOLL skills is being determinant in the extirpation with trustworthy margins of the non-palpable lesions cancer, with big safety instead harpoons that we used before.

[Sporangia ontogeny and sporogenesis of the lycopodium Huperzia brevifolia (Lycopodiaceae) from the high mountains of Colombia].  

PubMed

Huperzia brevifolia is one of the dominant species of the genus Huperzia living in paramos and superparamos from the Colombian Andes. A detailed study of the sporangium's ontogeny and sporogenesis was carried out using specimens collected at 4200m above sea level, in Parque Natural Nacional El Cocuy, Colombia. Small pieces of caulinar axis bearing sporangia were fixed, dehydrated, paraffin embedded, sectioned in a rotatory microtome, and stained using the common Safranin O-Fast Green technique; handmade cross sections were also made, stained with aqueous Toluidine Blue (TBO). The sporangia develops basipetally, a condition that allows observation of all the developmental stages taking place throughout the caulinar axis of adult plants. Each sporangium originates from a group of epidermal cells, axilar to the microphylls. These cells undergo active mitosis, and produce new external and internal cellular groups. The sporangium wall and the tapetum originate from the external group of cells, while the internal cellular group leads to the sporogenous tissue. Meiosis occur in the sporocytes and produce simultaneous types tetrads, each one giving rise four trilete spores, with foveolate ornamentation. During the sporangium ripening, the outermost layer of the wall develops anticlinally, and inner periclinal thickenings and the innermost one perform as a secretory tapetum, which persists until the spores are completely mature. All other cellular layers colapse. PMID:20073340

Classical morphology of plants as an elementary instance of classical invariant theory.  

PubMed

It has long been known that structural chemistry shows an intriguing correspondence with Classical Invariant Theory (CIT). Under this view, an algebraic binary form of the degree n corresponds to a chemical atom with valence n and each physical molecule or ion has an invariant-theoretic counterpart. This theory was developed using the Aronhold symbolical approach and the symbolical processes of convolution/transvection in CIT was characterized as a potential "accurate morphological method". However, CIT has not been applied to the formal morphology of living organisms. Based on the morphological interpretation of binary form, as well as the process of convolution/transvection, the First and Second Fundamental Theorems of CIT and the Nullforms of CIT, we show how CIT can be applied to the structure of plants, especially when conceptualized as a series of plant metamers (phytomers). We also show that the weight of the covariant/invariant that describes a morphological structure is a criterion of simplicity and, therefore, we argue that this allows us to formulate a parsimonious method of formal morphology. We demonstrate that the "theory of axilar bud" is the simplest treatment of the grass seedling/embryo. Our interpretations also represent Troll's bauplan of the angiosperms, the principle of variable proportions, morphological misfits, the basic types of stem segmentation, and Goethe's principle of metamorphosis in terms of CIT. Binary forms of different degrees might describe any repeated module of plant organisms. As bacteria, invertebrates, and higher vertebrates are all generally shared a metameric morphology, wider implications of the proposed symmetry between CIT and formal morphology of plants are apparent.

Pneumatocele selar a tensi?n: Reporte de un caso y revisi?n de la literatura  

PubMed Central

Introducción: El neumoencéfalo a tensión luego de la cirugía transesfenoidal es poco común. En la literatura existen pocos casos reportados en los cuales el aire se encuentra localizado exclusivamente en las regiones selar y supraselar, constituyendo un pneumatocele selar. En este artículo se describe un caso inusual de pneumatocele selar a tensión de presentación tardía. Descripción del caso: Una mujer de 57 años consultó por hemianopsia bitemporal. Previamente, ya se le había realizado una cirugía transnasal por un adenoma hipofisario y se le había colocado una derivación lumbo-peritoneal por la presencia de una fístula de líquido cefalorraquídeo. Además, se le había realizado una resección transcraneal de un componente intracavernoso del tumor y radiocirugía debido a la agresividad del mismo. Se llevó a cabo una resonancia magnética que demostró un pneumatocele selar y supraselar. Intervención: Se realizó un abordaje transciliar. La región selar estaba encapsulada por tejido cicatrizal debido a los procedimientos previos. Se abrió la cicatriz y el aire fue evacuado. Posteriormente, el piso selar fue cerrado con grasa y cola de fibrina. Despuós del procedimiento, su campo visual retornó a la normalidad. Un año después de su última cirugía, continua asintomática. Conclusión: El pneumatocele selar y supraselar a tensión es un hallazgo extremadamente raro luego de una cirugía transesfenoidal. Su manifestaciónw clínica sería la alteración visual debida a la compresión inferior de la vía óptica. El pneumatocele selar a tensión debe ser evacuado en un corto plazo.
