Angioedema hereditario
Osorio,Hugo Ernesto; Rodríguez,Jairo Antonio;
Acta Medica Colombiana , 2012,
Abstract: a 46 year-old woman affected by familiar, recurrent episodes of skin lesions with painful, occasionally pruriginous angioedema who had been hospitalized because of laryngeal compromise is presented. laboratory results include c3: 165.5 mg/dl, c4: 1 mg/dl, ch50 < 256 units, and c1 inhibidor 38 mg/dl. hereditary angioedema type i is diagnosed, patient is currently on treatment with anti-fibrynolytic and androgen, obtaining clinical improvement. a clinical emphasis in the diagnosis of hereditary angioedema is performed since misdiagnosis of this disease may lead to death as it happened to two patients's relatives. (acta med colomb 2012; 37: 34-37).
Angioedema hereditario Hereditary angioedema
Hugo Ernesto Osorio,Jairo Antonio Rodríguez
Acta Medica Colombiana , 2012,
Abstract: Se presenta el caso de una mujer de 46 a os, quien consulta por lesiones dérmicas episódicas de 28 a os de evolución, consistentes en edema doloroso ocasionalmente pruriginoso, súbito, recurrente, familiar, que compromete varias regiones corporales incluyendo la laringe. Por la gravedad de los episodios ha requerido repetidas hospitalizaciones en las que se ha recuperado mediante tratamiento sintomático. Se encuentran valores séricos de C3 165.5 mg/dL, C4 1 mg/dL, CH50 < 256 U, e inhibidor de C1 38 mg/dL. Se realiza diagnóstico de angioedema hereditario tipo I y se inicia tratamiento con antifibrinolíticos y andrógeno con mejoría de los síntomas. Se hace énfasis en la necesidad de sospechar la enfermedad clínicamente en pacientes con episodios recurrentes de angioedema sin urticaria con el fin de instaurar el tratamiento adecuado, por falla en dicha sospecha, dos de los familiares de la paciente infortunadamente fallecieron. (Acta Med Colomb 2012; 37: 34-37).

Abstract: background. dengue is the main arthropod -transmitted viral disease in the world with a growing number of cases in neiva, colombia. clinical presentation of dengue hemorrhagic fever (dhf) is showing compromise of organs different from endothelium which could be associated to the circulating serotype and/or host immunological factors. objetive. to alert about the association of multiple organic dysfunction (mod) and dhf. results. mod associated to dhf is described in three girls with an average of 16 months of age, two 7-months-old and 1 three year old. the evolution of fever at the beginning was 4 days; they had shock resistant to usual treatment with crystalloids and colloids with tachycardia, ventricular arrhythmia, increased cpk mb, ast and alt, coagulopathy with prolonged ptt and pt but without severe thrombocytopenia, metabolic alteration with acidemia and hypoglicemia in the three girls. score for mod was applied with an average of 23 and evidence of myocardial, hepatic and hematological major compromise. dengue 3 was showed by rt-pcr. discussion. similar reports are compared with these cases and probable physiopathological mechanisms are discussed. conclusion. it has to be stressed that dhf might affect different organs, because of this definition of severity in dengue has to be reconsidered. an early thinking in different organs affected might help to introduce an opportune intervention or treatment.
Temporal Evolution of Anodization Current of Porous Silicon Samples  [PDF]
Adriana Gutiérrez, Jairo Giraldo, Mario Enrique Rodríguez-García
Materials Sciences and Applications (MSA) , 2013, DOI: 10.4236/msa.2013.48A005
Abstract:

Temporal evolution of the anodization current of porous silicon samples was studied by means of a model of resistances connected in series that represented the temporal changes of the substrate and of the interface between the substrate and the electrolyte during the porous sample formation process. The porous samples were obtained by means of photoelectrochemical etching of (100) n-type silicon wafers with different resistivity values, all in the range of 1 - 25 Wcm. The samples were formed at room temperature in an electrolytic bath composed by a mixture of hydrofluoric acid (48%) and ethanol having a composition ratio of 1:1 in volume under potentiostatic condition (10 V and 20 V) and an etching time of 2 minutes using back illumination provided by a laser beam with a wavelength of 808 nm.

Biología y hábitos de Mahanarva andigena (Hemiptera: Cercopidae) en condiciones de casa de malla
Rodríguez Ch,Jairo; Peck,Daniel C.;
Revista Colombiana de Entomología , 2007,
Abstract: mahanarva andigena was detected in colombia for the first time in 1999, in the municipality of tumaco (nari?o), on the south pacific coast, associated with the hosts sorghum halepense and saccharum officinarum. in order to complement studies aimed at an understanding of the biology of other species of spittlebugs associated with cultivated grasses in colombia, this research was designed to establish an initial base on the morphological differentiation, duration of the developmental stages, and certain aspects of the reproductive biology. the morphological studies permitted the differentiation and characterization of the egg, nymph and adult, at the same time determining the duration of the life cycle under semi-controlled conditions. for the eggs (27°c, 100% r. h.), the mean time to eclosion was 16.4 days. for the nymphs (mean temperature min/max 19.5/29.9°c, 95% r. h.) the mean development time was 48.4 days, divided in 6.4, 8.6, 8.2, 10.1 and 15.1 days for the five instars, respectively. for the adults (mean temperature min/max 19.5/29.9°c, 95% r. h.), the mean longevity was 21.4 days, 25.6 days for the females and 18.3 days for the males. under the conditions of the study, the total duration of the life cycle of m. andigena was 75.5 days. m. andigena exhibited a flexibility for oviposition substrate, with a preference for uncovered soil with 51.2% of the recovered eggs; 16.4, 32.4 and 0% were recovered from soil under litter, surface of the stem, and the litter, respectively. the information provided strengthens certain patterns established for the spittlebug complex in grasses and broadens our understanding of the biological variation. as the first study on a spittlebug species associated with sugar cane in colombia, a base line is established for biological studies of spittlebugs as emerging pests of the sugar cane industry.
