Cephaloskeletal dysplasia (Taybi-Linder syndrome: osteodysplastic primordial dwarfism type III): report of two cases and review of the literature.

We report two unrelated infants with cephaloskeletal dysplasia or Taybi-Linder syndrome, also referred to as osteodysplastic primordial dwarfism Type III. They presented with peculiar facial features, microcephaly and skeletal and cerebral abnormalities documented radiographically and with cranial MRI and/or CT. Some dissimilarities were observed in the skeletal findings between the two patients, most likely reflecting phenotypic variability within the same disorder. Some radiographic features were shown to evolve with time in both patients. Also of interest is the unusually long survival of these patients, more than 4 years in the first and of over 6 years in the second.

Spondylo-epiphyso-metaphyseal dysplasia: an atypical variant.

In a 12 years, 10 months-old-girl with severe nanism we observed bone changes of unusual spondylo-epi-metaphyseal dysplasia (S.E.M.D.). The metaphyseal and epiphyseal changes in the long bones were symmetrical and mostly rhizomelic - with the involvement of the iliac bones, tarsal bones with irregular lesions and disproportionally long fibulae; these changes confirm the heterogeneity of the disease.

[Diagnosis by imaging in renal and urinary tract malformations. Comparison of echography and traditional radiological studies].

The diagnostic sensitivity of Ultrasound (US) was studied in 142 children with suspected kidney and urinary tract malformations. According to the clinical tests performed the patients underwent excretory urography (EU) and/or voiding cystouretrography (VCU); the results were compared to US findings. In the 75 patients with malformations, US proved to be extremely sensitive in abdominal renal ectopies, in "horseshoe" kidney, and in congenital obstructions of the ureteropelvic and vesico-ureteral junctions. US showed a higher sensitivity than EU in identifying multicystic kidney and in most cases of hypodysplasia. On the other hand, VCU was more accurate in vesico-ureteral reflux studies; US should thus be used in the follow-up of the patients undergoing medical therapy. EU must however be considered as the most important tool in the evaluation of early renal injuries and their possible development.

[Experience acquired over a 4-year period with the Vichi method in the study of bronchopulmonary changes in cystic fibrosis].

The classification of chest alterations in Cystic Fibrosis (CF) and related score proposed by Chrispin and Norman has been widely adopted in Europe and is still applied (although slightly modified) in most European Centres. Brasfield classification instead has been mostly used in the USA. Lately, however, to revise both classifications, the need has been felt, for a more precise correlation to anatomo-radiological data as well as for inclusion of headings which have not been taken into account so far. In 1980 one of the Authors (Vichi) worked out a new scoring system for the chest alterations of CF. Results are reported from a follow-up of 15 patients with CF carried out at the FC Centre of Meyer Ospedale in Florence from the late 1981 to 1985. The patients underwent periodic checkings including determination of clinical scoring system-according to Shwachman and Kulczychi modified by Doershuk-respiratory function tests, chest X-rays evaluated by three radiologists separately, following both Chrispin and Norman and Vichi scoring systems. The latter system has proved to be well correlated to clinical data and to the ordinary pulmonary function tests but it mainly presents a high observer reproducibility.

[Recurrent cystitis in young girls. Clinical and radiologic aspects].

The authors emphasise the importance of radiological investigation of all children with urological infections. The key studies are complete intravenous urography and retrograde cystography. A broad sub-division of situations may be used to draw a distinction between recurrent cystitis in the young girl with an organic cause (urethral stenosis) and recurrent cystitis of functional origin. Organic urethral stenosis may be diagnosed immediately on the basis of radiological findings of an association of vesical hypertrophy and a permanent narrowing of the distal urethra with proximal dilatation, persisting during the different phases of micturition. This possibility is rare. By contrast, functional causes are much more common: spasm of the striate sphincter, absence of inhibition of the bladder, neurological dysfunction resulting in a non-neurogenic neurogenic bladder. There remains recurrent cystitis due to insufficiently frequent micturition. Analysis of the factors actually responsible for recurrent infections in any given child may be made difficult when they are present in association.
