Immunoproteomic profile of in Mexican pediatric patients. Evidence of new allergen prospects.

: Apple () is a fruit commonly associated with allergic oral symptoms in the Mexican pediatric population; however, knowledge of its allergenic proteins is limited. This information is crucial as sensitization frequencies to specific allergens can vary among different populations. The main allergic symptomatology before apple ingestion derives from primary sensitizations induced by pollen, promoting cross-reactivity with the main allergenic protein of apple.

[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.

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.
