The aims of this study were: (i) to determine whether differences exist in the fine motor fluency and flexibility of three groups (children with attention-deficit/hyperactivity disorder [ADHD], children in whom ADHD is comorbid with developmental coordination disorder [DCD] [denoted as ADHD+DCD], and a typically developing control group); and (ii) to clarify whether the degree of severity of core symptoms affects performance. ⋯ Children with ADHD demonstrated proper fine motor fluency and flexibility, and deficient performance occurred when ADHD was comorbid with developmental coordination disorder. Children with ADHD had more difficulty implementing closed-loop movements that required higher levels of cognitive processing than those of their typically developing peers. Also, deficits in fine motor control were more pronounced when ADHD was combined with movement coordination problems. The severity of core symptoms had a greater effect on children with ADHD's fine motor flexibility than did fluency performance. In children with pure ADHD, unsmooth movement performance was highly related to the severity of core symptoms.

Comparative Study
Expression and activity of epithelial sodium channel in hyperoxia-induced bronchopulmonary dysplasia in neonatal rats.
The aim of the present study was to investigate the expression and activity of epithelial sodium channel (ENaC) in hyperoxia-induced bronchopulmonary dysplasia (BPD) in neonatal rats. ⋯ Hyperoxia upregulates the expression of ENaC, especially β- and γ-ENaC subunits, in both neonatal rat lung tissues and ATII cells. Hyperoxia also enhanced the activity of ENaC in neonatal rat ATII cells. Dysfunctional transport of Na(+) may not be a key factor involving pulmonary edema at the early stage of BPD.

The efficacy of early intervention programs for children with autism has been emphasized in many studies. However, access for people with autism to professional services in Poland is very limited and the burden of supporting a child's development often falls on parents, especially in families with low socioeconomic status and families living far away from big cities. Using Internet resources in planning and delivering individualized intervention may be useful. This study examined the effects of a home program of intervention based on the AutismPro system with elements of consultative therapy. ⋯ The results suggest that an intervention which combines the use of the Internet support tool and professional consultations may provide benefits to the children with autism. There are, however, methodological limitations of the study to be taken into account when interpreting the results.

A tubo-ovarian abscess (TOA) is a common complication of pelvic inflammatory disease in premenopausal women; however, in virginal females, TOAs are an exceedingly rare occurrence. Within this rare subset of patients, there is almost always an underlying condition, such as vaginal voiding, or a concomitant disease process. A virginal adolescent female with no prior medical history presented with a large pelvic mass which proved to be a TOA. ⋯ With only the organism, Streptococcus viridians, isolated in her cultures, an etiology of direct ascension from the lower genitourinary tract is implicated. We believe this to be the youngest case of a TOA occurring in a virginal adolescent female without a predisposing condition. A TOA should be considered in the differential diagnosis of pelvic masses in previously healthy pediatric patients regardless of their sexual activity.

A significant proportion of cases of tracheobronchial foreign body aspiration due to life-threatening condition is observed during childhood. The aim of the present study was to describe our experience with the diagnosis and treatment of foreign body aspirations during childhood and review published literature. ⋯ Tracheobronchial foreign body aspiration is a significant cause of childhood morbidity and mortality. Early diagnosis and treatment is of utmost importance. Rigid bronchoscopy under general anesthesia should be performed in all patients suspected of foreign body aspiration, which could minimize mortality and morbidity if performed by experienced personnel with safe methods.
