[Aggressive pediatric hip fibromatosis with severe joint destruction. A case report].

Fibrous or desmoid tumors are grouped under the term fibromatosis; there are several groups; the pediatric aggressive form is rare, especially the pelvis and/or hip presentation. This causes a variable degree of destruction of the surrounding tissues. It is a diagnosis by exclusion and histopathologic testing; treatment is always surgical and conservative treatment is indicated only for special locations and/or patient conditions.

[Sensitivity and specificity of the Tc-99m ciprofloxacin scan in pediatric osteomyelitis].

Introduction: The Tc-99m-ciprofloxacin complex, introduced in 1993, has been extensively evaluated all over the world with good results for the diagnosis of active bacterial osteoarticular infections. There are only a few publications on the use of this procedure in pediatric ages. In our study we evaluated the efficacy of the Tc-99m ciprofloxacin scan for the diagnosis of osteoarticular infections in the pediatric population assessing its sensitivity, specificity, and positive and negative predictive value.

[Minimally invasive surgery efficacy in children's forefoot].

Minimally invasive surgery (MIS) in children's forefoot is a technique that permits minimum tissue trauma assisted by fluoroscopic control. We evaluated the results of this modality of surgery in problems such as: claw toes, hallux valgus, exostosis, hammer toe, and bunionectomy. We had a complication for using the procedure with more revolutions per minute (rpm), which remind us of the importance of using 2000-8000 rpm.
