INTRODUCTION Urachal cysts are rare congenital anomalies that often prompt referral to the paediatric general surgeon because of their associated complications such as infection, abdominal pain and the young age at presentation. In this report we describe a rare case of fever of unknown origin caused by an urachal cyst which was successfully treated with incision and drainage only. Since the fi...

diagnosis of infected and affected dentine is an important factor in clininal restorative treatment of dentine. in this study, the ir and raman spectra of the sound dentine, infected dentine and affected dentine are reported. the structure of infected dentine and affected dentine has been compared with the sound dentine and hydroxyapatite. it is shown while the infected dentine has lost its str...

This study was conducted to evaluate the efficacy of oral administration of fenbendazole (20 mg/kg body weight) prior to and after experimental infection of immunosuppressed rabbits with Encephalitozoon cuniculi. A total of thirty rabbits were divided into five groups: NN (non-immunosuppressed; non-infected), IN (immunosuppressed; non-infected), IPI (immunosuppressed; protected-infected), ITI (...

objective: hepatitis c virus (hcv) is one of the most relevant persistent infections afflicting the human population. control of viral replication in hcv infection has been associated with the cellular component of the host immune response. several mechanisms have been proposed to explain this abnormal immune response, among them an altered activity of regulatory t cells (tregs) being the most ...

Eukaryotic high-mobility-group-box (HMGB) proteins are nuclear factors involved in chromatin remodeling and transcription regulation. When released into the extracellular milieu, HMGB1 acts as a proinflammatory cytokine that plays a central role in the pathogenesis of several immune-mediated inflammatory diseases. We found that the Plasmodium genome encodes two genuine HMGB factors, Plasmodium ...

We conducted monthly snail captures in Bananal, State of São Paulo, Brazil, between March 1998 and February 2001, to identify Schistosoma mansoni vectors, estimate seasonal population changes, and delimit foci. We also evaluated the impact of improvements in city water supply and basic sanitation facilities. We identified 28,651 vector specimens, 28,438 as Biomphalaria tenagophila, 49 of them (...

Retroperitoneal fibrosis, either idiopathic or associated with aortic inflammatory aneurysm, is a chronic fibrotic disease that causes progressive obstruction of ureters and vessels around the lower abdominal aorta. Treatment is often difficult (surgery) or hazardous (steroids). We report a case of a woman with retroperitoneal fibrosis associated with aortic inflammatory aneurysm, who was succe...

We present the first clinical report of the successful treatment of an infected thoracic aortic arch aneurysm with the use of endovascular repair as a bridge to second-stage open operation. A 70-year-old patient underwent urgent endovascular repair through the right femoral approach because of a diagnosis of sepsis and impending rupture of an infected thoracic aortic arch aneurysm. After 2 week...

Dog bites account for approximately one of 200 emergency room visits. The majority of bites are from dogs known to the victim. Due to the numerous small compartments and the thin covering of soft tissue over the bones and joints, bite wounds to the hand are more likely to become infected that are bites to the arm, leg, or face. Improper management can result in significant morbidity and prolong...
