Background: Many intracranial lesions can induce psychotic symptoms. Arachonoid cyst is one of the suspicious etiologies. A possible link between arachnoid cyst and psychosis gives an interest to the pathogenesis of psychotic symptoms. Here, we present a case of schizophrenia with a large cerebellar arachnoid cyst. Case Presentation: Ms. Lu is a 31-year-old woman with schizophrenia for 7 years...

scid mice naturally infected with Pneumocystis carinii and inoculated with a normally apathogenic pneumovirus had significantly higher P. carinii cyst counts and developed significantly more severe P. carinii-related disease than did sham-inoculated, P. carinii-infected scid mice. P. carinii-free, virus-infected scid mice survived for 2 months despite high pulmonary virus titers. These results ...

Hydatid cyst is a common disease in our country. The revelation by peritoneal hydatidosis is rare in children. We report the case of a 15 years old adolescent. History of the disease began a year by the occurrence of acute abdominal pain starting at the right hypochondrium; resolved with symptomatic treatment; no assessment was initially performed. The evolution was characterized by the recurre...

To find the most suitable indicator of viral and parasitic contamination of drinking water, large-volume samples were collected and analyzed for the presence of pathogens (cultivable human enteric viruses, Giardia lamblia cysts, and Cryptosporidium oocysts) and potential indicators (somatic and male-specific coliphages, Clostridium perfringens). The samples were obtained from three water treatm...

BACKGROUND Periapical lesions occur in response to chronic irritation in periapical tissue, generally resulting from an infected root canal. Specific etiological agents of induction, participating cell population and growth factors associated with maintenance and resolution of periapical lesions are incompletely understood. Among the cells found in periapical lesions, mast cells have been impli...

Toxoplasma gondii is an obligate intracellular protozoan parasite presenting as a zoonotic infection distributed worldwide. In HIV-positive individuals, it causes severe opportunistic infections, which is of major public health concern as it results in physical and psychological disabilities. In healthy immunocompetent individuals, it causes asymptomatic chronic persistent infections, but in im...

BACKGROUND Giardia lamblia is one of the most common protozoal infections in human especially children. Metronidazol (MTZ) is the drug of choice for treatment of giardiasis; its chemical composition possesses major threats and is becoming less sensitive. This study aimed to search for natural extracts alternative to MTZ. METHODS In-vivo effects of dichloromethane extracts of ginger and cinnam...
