Is the E133K allele of VG5Q associated with Klippel-Trenaunay and other overgrowth syndromes?

BACKGROUND: It has been reported that the activating mutation, E133K, in the angiogenic factor VG5Q (formally named AGGF1) causes Klippel-Trenaunay Syndrome (KTS), a rare vascular disease associated with asymmetric overgrowth. This proposal followed from the observation that five out of 130 KTS patients were constitutionally heterozygous for VG5Q, E133K. OBJECTIVE: To explore the possibility that VG5Q, and specifically E133K, is implicated in other mosaic overgrowth syndromes. RESULTS: 24 patients were analysed for this sequence change. One patient was constitutionally heterozygous for E133K. Analysis of both parents revealed that the patient's mother, who was healthy, also carried E133K. An analysis of 275 healthy controls showed that 3.3% (9/275) of the population were carriers of E133K. CONCLUSIONS: The findings bring into question the assertion that VG5Q, E133K is a mutation and that it causes KTS.

Osteofibrous dysplasia of the tibia. Is there a need for a radical surgical approach?

Osteofibrous dysplasia is an unusual developmental condition of childhood, which almost exclusively affects the tibia. It is thought to follow a slowly progressive course and to stabilise after skeletal maturity. The possible link with adamantinoma is controversial and some authors believe that they are part of one histological process. We retrospectively reviewed 16 patients who were diagnosed as having osteofibrous dysplasia initially or on the final histological examination. Their management was diverse, depending on the severity of symptoms and the extent of the lesion. Definitive (extraperiosteal) surgery was localised "shark-bite" excision for small lesions in five patients. Extensive lesions were treated by segmental excision and fibular autograft in six patients, external fixation and bone transport in four and proximal tibial replacement in one. One patient who had a fibular autograft required further excision and bone transport for recurrence. Six initially underwent curettage and all had recurrence. There were no recurrences after localised extraperiosteal excision or bone transport. There were three confirmed cases of adamantinoma. The relevant literature is reviewed. We recommend extraperiosteal excision in all cases of osteofibrous dysplasia, with segmental excision and reconstruction in more extensive lesions.

Walking problems in young children.

This article attempts to define normal development throughout childhood and provide straightforward advice in the physical assessment of the child in this situation. It also attempts to outline the groups of conditions that lead to walking abnormalities and highlight the salient physical features and special investigations that are required to make these diagnoses with confidence.
