ABSTRACT

Introducción: La infestación por áscaris consttuye un problema de salud pública importante en áreas endémicas, provocando en algunos casos complicacionesque requieren la intervención del cirujano. El propósito del presente estudio es analizar las complicaciones quirúrgicas de la ascaridiasis,en nuestro medio.Diseño, lugar y partcipantes: se realizó un estudio descriptvo retrospectvo de los pacientes que presentaron complicaciones quirúrgicas debido a lainfestación por A. lumbricoides de enero de 1999 a marzo de 2015 que fueron tratados en la unidad de cirugía pediátrica del hospital general San Juande Dios.Resultados: Ingresaron 47 pacientes con infestación por áscaris, comprendidos en las edades de 1 a 13 años. Hubo 39 pacientes con obstrucción intestnal,7 con ascaridiasis en el colédoco y 1 con apendicits por áscaris. El diagnóstco de los 39 pacientes con oclusión intestnal por áscaris fue clínicoy con rayos X simple de abdomen, 19 resolvieron con tratamiento médico y 20 requirieron de tratamiento quirúrgico. Los pacientes con áscaris en elcolédoco fueron diagnostcados por USG a 1 se le logró extraer el áscaris por CPRE mientras que a los 6 restantes fue necesario la exploración de la víabiliar por laparotomía. El diagnóstco de la apendicits secundario a la obstrucción por áscaris se realizó trans operatoriamente. La morbilidad observadafue del 21% (10/47) de los pacientes: 8 presentaron respuesta infamatoria sistémica y 2 dehisencias de la anastomosis intestnal. La mortalidadfue del 2% (1/47): un paciente con fallo orgánico múltple por sepsis abdominal y desnutrición.Conclusiones: en este estudio, las complicaciones de la infestación por áscaris fueron la obstrucción intestnal, obstrucción de la vía biliar y apendicits...


Introducton: In endemic areas, ascariasis is an important public health problem. In cases of severe infestaton, some cases need to be surgically treated.The aim of this study is to analyze surgical complicatons of childhood ascariasis in our insttuton.Design, Place and Partcipants: A retrospectve study of all patents with ascariasis, from 1999 to 2015, evaluated in the surgical pediatric unit at SanJuan de Dios General Hospital.Results: We analyzed 47 patents with ascariasis, age range 1 to 13 years old. There were 39 patents with intestnal obstructon due to ascariasis, 7 withcholedochal ascariasis and 1 with appendiceal ascariasis. Diagnosis of intestnal obstructon due to ascariasis was made with clinical evaluaton andplain abdominal radiography. Of the 39 patents with abdominal obstructon, 19 resolved with medical treatment and 20 required surgical interventon.Patents with choledochal ascariasis were diagnosed by ultrasonography. In one patent, extracton of the worm was possible with endoscopic retrogradecholangiopancreatography, in the remaining 6 patents, open common bile duct exploraton was required. Diagnosis of the appendiceal ascariasiswas made during appendectomy without previous clinical suspicion. Serious morbidity was 21% (10/47): 8 patents with severe infammatory responseand 2 anastomosis dehiscences. Mortality was 2% (1/47), a patent with multple organ failure, abdominal sepsis and malnourishment. Morbidity andmortality occurred only in patents with intestnal obstructon due to ascariasis. Conclusions: In this study, complicatons of ascariasis were intestnal obstructon, choledochal obstructon and acute appendicits...

ABSTRACT

Anaerobic BTEX biodegradation was tested in batch experiments using an anaerobic sediment as inoculum under Fe(III) and Mn(IV) reducing conditions. All BTEX were degraded under the conditions tested, specially under Mn(IV) reducing conditions, where benzene was degraded at a rate of 0.8 micromol l(-1) d(-1), significantly much faster than Fe(III) reducing conditions. Under Fe(III) reducing conditions, ethylbenzene was the compound that degraded at the faster rate of 0.19 micromol l(-1) d(-1). Mn(IV) reducing conditions are energetically more favourable than Fe(III), therefore, BTEX were more rapidly degraded under Mn(IV) reducing conditions. These results represent the first report of the degradation of benzene with Mn(IV) as the final electron acceptor. Amorphous manganese oxide is a natural widely distributed metal in groundwater, where it can be microbiologically reduced, leading to the degradation of monoaromatic compounds.
