Eleven children aged 5-9 years with maxillodental abnormalities were treated using positioners. Negative effects of positioners and activators (increase of dental caries, hygienic index, and acid resistance of the enamel) are analyzed.

Although many variations regarding lobar or segmental bronchial subdivisions have been described, abnormal bronchi originating from the trachea or main bronchi are relatively rare. These abnormalities can remain undetectable as they usually do not present with symptoms; however, they may pose major obstacles during surgery especially when accompanied by bronchial wall abnormalities.

A series of cervical myelograms performed by direct puncture resulted in almost identical incidence of side effects, more contrast within the skull, more frequent EEG abnormalities and only slightly better radiographic quality than in a comparable series of patients in whom the contrast was run up from the lumbar region.

Ground reaction forces (GRF) reflect the force history of human body contact with the ground. The purpose of this study was to explore human gait abnormalities due to planovalgus by comparing vertical GRF data between individuals with planovalgus and those with neutrally aligned feet. Second we estimated associations between various measurements and vertical GRF parameters in a pediatric popula...

Despite the potentially important roles of untranslated RNAs in cellular form or function, genes encoding such RNAs have until now received surprisingly little attention. One such gene encodes BC1 RNA, a small non-mRNA that is delivered to dendritic microdomains in neurons. We have now eliminated the BC1 RNA gene in mice. Three independent founder lines were established from separate embryonic ...

Functional magnetic resonance imaging has emerged as a powerful tool for mapping the neurologic underpinnings of sensory, motor and cognitive function. Much of this evolution carries assumptions about the subject population under study and, in particular, the neurologic status of subjects entered into studies either as healthy controls or as belonging to a specific disease group. Recent reports...

Accurate recognition and reporting of spine abnormalities on MRI requires knowledge of normal anatomy and its variants. This article deals with common normal variants, points out pitfalls which may be sources of errors in interpretation and describes imaging artifacts which are essential to be recognized and not mistaken for true pathologies.

The present study examined the relation between anxiety and depression and threat perception abnormalities. Children were exposed to stories describing social situations. Some of the stories were ambiguous (i.e., these stories contained information that could be interpreted as threatening) whereas other stories were non-threatening (i.e., these stories contained no obvious trace of threat). Fro...

The authors report the case of a five and a half year-old-boy with symptomatic MRI abnormalities of the ischiopubic synchondrosis. The concept of "ischiopubic osteochondritis" is reviewed in the light of modern imaging, and the importance of its differentiation from different pathological entities such as osteomyelitis, tumour, fracture or other pathologic entities is recalled.
