Parasitosis intestinales. La endoscopía y el estudio anatomopatológico como herramientas auxiliares diagnosticas en Strongyloidiasis Stercolaris / Intestinal parasitosis. endoscopy and anatomopathological study as auxiliary tools diagnostic in Strongyloidiasis Stercolaris

Introducción: La Strongyloidiasis es una parasitosis intestinal producida por un nematodo de distribución mundial, es endémica en zonas tropicales. Los métodos convencionales de diagnósticos suelen no ser lo suficientemente sensibles ni específicos. La endoscopia ha aumentado la sensibilidad de realizar mejores diagnósticos. Así es como la biopsia gástrica y/o duodenal juegan un rol importantísimo y se considera que los hallazgos endoscópicos son útiles como marcadores de severidad de la infección y obtención del agente etiológico. Objetivos: Realizar una revisión bibliográfica sobre la fisiopatogénesis y signo sintomatología del Strongyloides Stercoralis. Demostrar la utilidad de la endoscopía para evaluar inmenidad o daño de la mucosa duodenal como signo directo de organicidad y como método de obtención de muestras con el fin de realizar la observación directa del agente patógeno causal. Material y Método: Estudio observacional. Transversal. Retrospectivo. Se tuvieron en cuenta las endoscopías realizadas en el Servicio de Endoscopía del Hospital Español de Buenos Aires desde junio de 2016 a junio 2018. Resultados: Se realizaron 5286 estudios endoscópicos que constituyeron el 100% de la muestra. El 0,0189% (1 una endoscopía) de las endoscopías realizadas correspondieron a duodenitis inespecífica asociada a estudio anatomopatológico que confirma parasitosis intestinal por Strongiloidesis stercolaris. Discusión: Los principales síntomas clínicos de presentación de este nematodosis son náuseas, vómitos, anorexia, diarrea, pérdida de peso, y dolor abdominal, que frecuentemente confunden la etiología e imitan los síntomas de otras enfermedades, como en el caso de nuestro paciente. Tener en cuenta signosintomatologia atípica como refiere la World Gastroenterology Organization en su Practice Guidelines aumenta la sospecha diagnóstica Conclusión: La endoscopia digestiva alta es una herramienta diagnostica muy útil cuando la signo sintomatología no es muy clara. Una de las principales claves para hacer el diagnostico es tener un indicio de sospecha.

ntroduction: Strongyloidiasis is an intestinal parasitosis produced by a nematode of worldwide distribution, endemic in tropical areas., The conventional methods of diagnosis are usually not sensitive or specific enough. Endoscopy has increased the sensibility of making better diagnoses, as well as gastric and / or duodenal biopsy; plays a very important role and it is considered that the endoscopic findings are useful as markers of infection severity and in obtaining the etiological agent. Objectives: Carrying out a bibliographic review on the pathogenesis and signosyntomathology of Strongyloides Stercorali symptomatology. To demonstrate the usefulness of endoscopy to evaluate indemnity or damage of the duodenal mucosa as a direct sign of organicity and as a simple obtaining method in order to perform direct observation of the causative pathogen. Materials and Methods: Observational study. Cross. Retrospective. Endoscopies performed at the Endoscopy Service of the Hospital Español de Buenos Aires from June 2016 to June 2018 were taken into account. Results: There were 5286 endoscopic studies that constituted 100% of the sample. The 0.0189% (1 endoscopy) of the endoscopies performed corresponded to nonspecific duodenitis associated with an anatomopathological study that confirmed intestinal parasites by Strongiloidesis stercolaris. Discussion: The main clinical symptoms of this nematode are nausea, vomiting, anorexia, diarrhea, weight loss, and abdominal pain that frequently confuse the etiology and mimic the symptoms of other diseases, as in the case of our patient. Taking into account atypical signs and symptoms as the World Gastroenterology Organization refers in its Practice Guidelines increases diagnostic suspicion Conclusion: Upper digestive endoscopy is a very useful diagnostic tool when the signs and symptoms are not very clear. One of the main keys to make the diagnosis is to have an indication of diagnostic suspicion

Screening for opportunistic intestinal parasites in HIV/AIDS patients, attending the services of medical care in three different hospitals, Southern Ethiopia

Background and study aim: Diagnostic examination of stools for opportunistic intestinal parasites in HIV/AIDS patients is given less attention than it should be. The suspected opportunistic intestinal parasites such as Cryptosporidium parvum, Cyclospora cayentanensis, Toxoplasma gondii, Isospora belli and the symptom of explosive watery diarrhea they cause as well as others including Strongyloides stercoralis are the threat against the well-being of HIV/AIDS patients. The objective of this study is to demonstrate the indispensable necessity to free HIV/AIDS patients (who are under medical care in 3 different hospitals, Southern Ethiopia), from opportunistic intestinal parasites using diagnostic examination of stools followed by prompt curative treatment during every safety time interval. Patients and methods: Fresh stools samples from a total sample size of 710 HIV/AIDS patients were taken and examined in the parasitology laboratory, Dilla University, for the suspected intestinal opportunistic parasites. The methods employed to identify the intestinal parasites included observations in : wet mount, formalin-ether concentration technique, and permanent slide preparation as well as Baermann apparatus method for Strongyloides stercoralis. Result: Out of 710 HIV/AIDS patients examined 196 were found to be positive for 6 different species of the suspected intestinal parasites (infection rate of these parasites in the population of HIV/AIDS patients of the 3 different hospitals being The six species of parasites isolated from fresh stools samples were: Ascaris lumbricoides, Strongyloides stercoralis, Entameba histolytica, Giardia lamblia, Balantidium coli, and Trichuris trichiura. Conclusion: Reasonably planned successive safety time intervals must be attended continuously by HIV/AIDS patients without interruption to utilize the services of medical care in order to avoid/ neutralize the potential opportunistic infections and reinfections; otherwise, the fulminant death can turn to be true. The safety and well-being of those HIV-infected patients who attend all the medical services & advices provided by clinical experts is not different from that of HIV-noninfected individuals without any trace of exaggeration

Scanning electron microscope observations on the digenean intestinal parasite astiotrema reinferum [plagiorchiidae]

The body surface of adult digenean intestinal parasite Astiotrema reniferum has been studied using scanning electron microscopy [SEM]. The posterior region of the body forms a slender stalk terminating with two ventrolateral lobes. The lobes are armed with numerous large spine that are sharply pointed and oriented in all directions. There are regional variations in the distribution of spines all over the body. The spines are abundant on the general body surface of the head region, the rim of the oral sucker, the inner lip of the ventral sucker, and on the posterior ventrolateral lobes. No spines were observed on the genital pore and on the excretory opening. The sensory papillae found on both the oral and ventral suckers are arranged in a bilateral symmetrical patterns. They are dome shaped; some of them possess a short knob-like process and others have no process. The papillae are more abundant on the oral sucker than on the ventral sucker. The possible functions of the spines and sensory papillae are discussed relative to their position
