Endoscopic retrieval of gastric trichophytobezoar: Case report of a 12-year-old girl with trichophagia.

Rationale: Trichophytobezoars, which are composed of hair and plant fibers, are usually located in the stomach. They are often associated with trichophagia and trichotillomania. The most commonly reported methods of trichophytobezoar treatment are open surgery and laparoscopic retrieval; there are few reports of endoscopic removal of trichophytobezoars.

Relationships between Th1/Th2 cytokine profiles and chest radiographic manifestations in childhood pneumonia.

Background: pneumonia (MPP) is one of the most common childhood community-acquired pneumonias, and the chest radiograph usually shows bronchial pneumonia, segmental/lobar pneumonia, or segmental/lobar pneumonia with pleural effusion. The imbalance of Th1/Th2 function after infection is an important immunological mechanism of MPP. In this study, we aimed to evaluate the correlations between Th1/Th2 cytokine profiles and chest radiographic manifestations in MPP children.
