A Protocol for Diagnosis and Management of Cerebrospinal Shunt Infections and other Infectious Conditions in Neurosurgical Practice

Infections of the cerebrospinal shunts and other neurosurgical structures are not uncommon in the clinical practice. These infections are mostly clinical emergencies carrying negative prognostic impacts on the patients as well as spending healthcare resources. The low pathogenicity nature of some implicated pathogens results in minimal physical signs that may complicate the diagnosis and mislea...

بررسی رفتارهای پیشگیری کننده از عفونت ادراری بر اساس الگوی اعتقاد بهداشتی (HBM) در مادران دارای دختر کمتر از 6 سال

  Background :Urinary tract infection is the second common infection in children. In the first year of life, UTI is more common in boys than girls but thereafter the incidence rate becomes much more common in young girls. UTI complication in children is various, such as early hypertension, impaired glomerular function, proteinuria and finally, end stage renal failure.   Method: The objective of...

The Effect of Material Properties on Sensitivity of the Microelectromechanical Systems Piezoelectric Hydrophone

In this paper, we present mathematical analyses to consider the effect of material properties on the sensitivity of the Microelectromechanical systems (MEMS) piezoelectric hydrophone and improve the sensitivity by choosing the proper material. The selected structure in the present paper is a piezoelectric hydrophone able to work at low frequencies. The piezoelectric hydrophones are widely used ...

Quantitative assessment of acoustic intensity in the focused ultrasound field using hydrophone and infrared imaging.

With the popularity of ultrasound therapy in clinics, characterization of the acoustic field is important not only to the tolerability and efficiency of ablation, but also for treatment planning. A quantitative method was introduced to assess the intensity distribution of a focused ultrasound beam using a hydrophone and an infrared camera with no prior knowledge of the acoustic and thermal para...
