Hydatidosis is a common infestation caused by Echinococcus spp. Solitary hydatid cyst of the lung is not uncommon but coexistence of two or more pulmonary cysts are less common. These cysts may drain into the bronchial tree or very rarely into the pleural cavity which causes a poor outcome. Certain people such as slaughters, tanners, stockbreeders,...

... of the fluid showed numer- ous scolices. The patient underwent left thoracotomy; pleural decortication and complete enucleation of the peripherally situated cyst were performed. During the hospital course, follow-up CXR showed an air-fluid level in the unruptured cyst. Re- peated CT revealed detachment of the cyst membrane in the larger cyst (Fig. 2). The second complicated cyst was controlled by pharmacotherapy with albendazole (15 mg/kg divided in two doses/day taken with meal for four weeks followed by a 14- day albendazole-free period to be repeated for three cycles). After 10 days of hospital- ization, he was discharged in good health with medication. After 10 weeks of follow- ...

... Los factores de riesgo para adquirirla son la dedicación a la agricultura, habitar o ir a zonas rurales, tener contacto con perros sin cuidados veterinarios (los perros son la principal fuente de infección para los seres humanos) o alimentados con vísceras contaminadas (en el entorno rural el ciclo biológico se da entre ovejas y perros pastores), asistencia a cacerías, consumo de alimentos al aire libre cerca de excrementos de perro (perros que deambulan libremente y tienen acceso a los despojos) o de otro hospedero definitivo, consumo de agua no hervida o procesada, y consumo de frutas sin lavar y desinfectar 8 . También se mencionan ciertas profesiones como factor de riesgo: matarifes, curtidores, ganaderos, pastores, carniceros y veterinarios 9 . En nuestro caso, la paciente no tenía ningún factor de riesgo importante en la primera ocasión, y en la recurrencia su único antecedente importante era la cirugía 19 años antes por un quiste hidatídico. ...
El quiste hidatídico (hidatidosis o equinococosis) es una zoonosis endémica causada por la ingesta de huevos de Echinococcus. Esta enfermedad se localiza en el hígado, pero también puede encontrarse en otros sitios. Puede ser asintomática o presentarse con molestias por compresión o choque anafiláctico por rotura del quiste. Puede tener recurrencias. El diagnóstico se realiza por los síntomas y los hallazgos en imagenología. En ocasiones se realizan pruebas serológicas. El diagnóstico se confirma con la observación directa del parásito. El tratamiento es una combinación de antihelmíntico con drenaje mínimamente invasivo o quirúrgico. Se reporta el caso de una paciente con quistes hidatídicos recurrentes en el abdomen.

Description Strongyloides stercoralis is a soil-transmitted helminth that causes strongyloidiasis, a chronic parasitic infection in humans. S. stercoralis is one of several worm species that cause soil-transmitted helminthiasis, a neglected tropical disease. Herein, we discuss a 78-year-old female residing in a nursing home presenting with abdominal pain and shortness of breath. During a thoracentesis, physicians found multiple rhabditoid larvae consistent with S. stercoralis. However, before the procedure, a serial assessment of stool sample was performed and failed to demonstrate a parasitic infestation. Many of those infected with S. stercoralis are asymptomatic. Lack of symptoms and low sensitivity in traditional parasitological testing hampers and delays the diagnosis of strongyloidiasis. This case serves as a reminder to consider helminthic disease in the differential diagnosis.
... Human echinococcosis (Hydatid disease) is a parasitic disease which is most commonly caused by Echinococcus granulosus. The hydatid disease is commonly seen in slaughterers, tanners, stockbreeders, shepherds, butchers, and veterinarians or any job which makes a person to work closely with animals [6]. ...
The coexisting presence of hydatid disease with aspergillus colonization is a rare finding. The 20-year-old presented with symptoms of hemoptysis with past history of tuberculosis. On further evaluation, the patient was diagnosed as a case of aspergilloma and managed conservatively. After one year of presenting with similar complaints, the patient was turned out to be hydatid disease with aspergillus colonization on the basis of clinic-radiological and bronchoscopic evaluation. Till now only a few case reports have been reported. We report a unique case report of a similar presentation.
... Its ranges is throughout Asia, Australia, southern Europe, Africa and the Middle East [6], [7]. Some occupations which work closely with animals have the highest risk of the infection, such as tanners, slaughterhouse workers, shepherds, butchers, stockbreeders and veterinarians [8]. CE is endemic in regions all over the world; e.g., some parts of Europe are endemic regions for hydatid cyst infection. ...
Background: Hydatid cyst is a zoonotic infection caused by Echinococcosis granulosus. Primary single-intramuscular hydatid disease is rare, even in endemic regions of the world. Here we report the case of exceptional thigh mass due to a hydatid cyst in an Iranian man.
Case presentation: An 86-year-old man, initially presented to Velayat teaching hospital surgery clinic in May 2017 with a single right-thigh mass, but physical examinations of other organs were unremarkable. Based on sonographic findings, the differential diagnosis was hydatid cyst. He underwent surgical resection of the cyst. Histopathological results confirmed the diagnosis. There was no evidence of recurrence of the lesion during the 23-month follow-up.
Conclusion: Increase thigh mass due to a hydatid cyst is a rare event. In endemic regions with the presence of hydatid cysts, especially physicians of surgical clinics have to consider differential diagnosis of hydatid cysts in unusual locations in case of such a lesion.
... In addition to the time and cost, the biohazard risk also cannot be ignored. Oral feeding with parasitic eggs can cause high infection risk for researchers and requires a high-level biohazard lab to perform the studies [4][5][6][7] . Thus, the development of a highly accurate animal model with low contamination risk to interpret short-term research results would be beneficial. ...
... Different parasitic stages have been employed, such as parenterally with eggs, hatched eggs, or activated oncospheres. In addition to the low infection rate, the generation of experimental animals orally with eggs might pose potential contamination risks to the laboratory personnel who are exposed to feces of the infected mouse and the liver with hydatid cysts [3,[5][6][7] . In this study, an effective animal model was established to mimic the natural infection route and course of echinococcosis in humans. ...
AIM
To investigate a safer way to set up the disease model of cystic echinococcosis without contamination risk and develop a novel experimental murine model of hepatic cystic echinococcosis.
METHODS
C57B/6 mice were injected with human protoscolices of three different concentrations via the portal vein. The mice were followed for 10 mo by ultrasound, gross anatomy, and pathological and immunological examinations. The protoscolex migration in the portal vein, hydatid cyst growth, host immune reaction, and hepatic histopathology were examined periodically.
RESULTS
The infection rates in the mice in the high, medium, and low concentration groups were 90%, 100%, and 63.6%, respectively. The protoscolices migrated in the portal vein with blood flow, settled in the liver, and developed into orthotopic hepatic hydatid cysts, resembling the natural infection route and course.
CONCLUSION
We have established an improved experimental model of hepatic cystic echinococcosis with low biohazard risk but stable growing dynamics and immune reaction. It is especially useful for new anti-parasite medication trials against hydatid disease.

... Besides, certain people including shepherds, slaughters, stockbreeders, farmers, butchers, veterinarians, tanners and all whose career makes them to work closely with animals are at higher risk of the disease (Farahmand and Yadollahi 2010). Among occupations vegetable sellers are important group who are at high risk of acquiring the infection because of their close contact with raw vegetables which can transmit E. granulosus eggs. ...
Cystic echinococcosis (CE) is considered as an occupational infection and among different careers greengroceries have a close contact with raw vegetables which can transmit eggs of Echinococcus granulosus. Therefore, the objective of this survey was to determine the seroprevalence of CE among greengroceries using ELISA test in Mazandaran and Gilan Provinces, northern Iran. Overall, 160 serum samples (60 male and 100 female) were collected from greengroceries in Mazandaran and Gilan Provinces, 2012. Sera were surveyed employing ELISA assay for diagnosis of CE. In addition, before sampling, a questionnaire was filled out for each subject. Seropositivity was 2.4 % (four cases) and females 1.8 % (three cases) were more positive compared to males 0.8 % (one case). Age group of 40–60 years encompassed the highest rate of positivity (1.8 %) and the least rate was in 20–40 years old age group (0 %). Besides, 1.8 % of seropositive subjects were dog owner, unaware of the disease and lives in rural areas. In conclusion, seroprevalence of cystic hydatid disease among greengroceries is relatively high in Mazandaran and Gilan Provinces. More continuous serological researches and preventive measures should be taken into consideration owing to the significance of the disease.
... The disease causes severe public health problems in some endemic foci (2). Certain people such as slaughterers, tanners, stockbreeders, shepherds, butchers, veterinarians and all whose job makes them to work closely with animals are at higher risk of the infection (3). ...
Background: Cystic echinococcosis (CE) is a parasitic disease characterized by cystic lesions mainly in the liver. The diagnosis relies on clinical, laboratory, and radiological examination.
Aim: To explore the clinical, radiological, and biological features of patients with CE in the middle region of the Nile Delta, Egypt.
Patients and methods: From March 2012 to February 2014, this study was conducted on 45 patients, aged 20–65 years. Patients were subjected to clinical, laboratory, and radiological assessment using conventional X-ray chest, ultrasound and multi-detector CT of the abdomen and chest.
Results: This study identified the epidemiological, clinical, laboratory, and radiological characteristics of patients with CE in the middle Delta region, Egypt. The CT may display the same findings as US in diagnosing and staging of most cases; however, CT is more superior to US in the evaluation of heavily calcified cysts, small inaccessible cysts, and pulmonary hydatid cysts.
Conclusion: Biological markers seem neither sensitive nor specific, whereas the serological tests, preferably two different techniques, are useful. Ultrasound showed high accuracy rate, but CT, whenever possible, should be employed as it provides additional diagnostic value.
