Pediatricians should acquire multiple skills during their professional training, including procedural skills. Skill acquisition requires knowledge on theoretical bases, direct observation and, lastly, supervised repetitive practice. Training using simulators allows to learn procedures in a controlled setting, ensuring patients' safety, integrating this as a learning stage prior to the actual co...

background: although a variety of methods have been suggested to reduce stress, anxiety and pain intensity due to spinal needle skin puncture, their adverse effects restrict theirs widespread administration. in this study we evaluated the effects of oral tizanidine on the reduction of pain caused by spinal needle puncture and hemodynamic responses. methods : in this double blind randomized clin...

BACKGROUND Left atrial catheterization through transseptal puncture is frequently performed in cardiac catheterization procedures. Appropriate transseptal puncture is critical to achieve procedural success. AIMS The aim of the study is to evaluate the feasibility of selective transseptal punctures, using a modified radiofrequency (RF) transseptal needle and transesophageal echocardiography (T...

We report a premature neonate who developed bizarre multiple skin lesions after being cured from hyaline membrane disease. These lesions were thought initially as multiple abscesses at the puncture sites, which did not respond to the conventional antibiotics. Biopsy of the skin lesion was of great importance in reaching the diagnosis of congenital tuberculosis as cutaneous disease.

Three cases of multiple spinal canal meningiomas are presented, bringing the total number of documented cases in the American literature to nine. While the exact incidence of multiple spinal meningiomas is difficult to determine, their possible occurrence warrants careful myelographic examination of the whole spinal canal, particularly if multiple clinical levels are present. When a complete bl...
