[Evaluation of 3-year ultrasound screening in congenital hip dysplasia. Comparison of clinical examination, risk factors and ultrasonography. Interpretation of Graf type IIA grading and the most suitable age for 1st ultrasonography]. / Valutazione di tre anni di screening ecografico della displasia congenita delle anche. Confronto tra clinica, fattori di rischio ed ecografia. Interpretazione dei quadri IIA di Graf ed età più idonea per l'esecuzione del primo esame ecografico.

2237 infants (1210 females, 1027 males) aged two days-six months were screened by ultrasound for congenital dysplasia of the hip (CDH). 21 infants (0.93%) were detected having CDH by ultrasound examination. We have evaluated the concordance between ultrasonography, clinical examination (Ortolani's examination) and risk factors. Of the 21 infants with CDH, 10 (47.6%) had a positivity of Ortolani's examination, 13 (61.9%) had at least one risk factor, 3 (14.2%) had a negative clinical evaluation and no risk factors. Our data indicates the superiority of ultrasonography as compared with physical examination alone, for the diagnosis of CDH. Infants presenting any risk factors for CDH and/or a positive Ortolani's examination should have an early ultrasound evaluation in order to allow initiation of treatment early on, while in infants with negative clinical findings and no risk factors, it should be postponed to avoid the frequent finding of physiological immaturity of the hip. The finding of a high rate of infants that presented a grade IIA in the Graf's grading system during their first month of life and that evolved favourably in the absence of risk factors, and which required further sonograms, indicates the period between the second and the third month as the most desirable for ultrasound screening of CDH.

[Transrectal echography in the diagnosis of non-palpable prostatic carcinoma]. / L'ecografia transrettale nella diagnosi del carcinoma prostatico non palpabile.

285 affected by BPH have been evaluated by transrectal ultrasound. All the patients had a palpably normal prostate without abnormality suggestive of cancer. 56 patients (19.6%) presented ultrasonic abnormality areas. Under ultrasound guidance, biopsy was done by the transperineal route and biopsy material showed the presence of prostatic carcinoma in 24 patients (8.3%). 6 of these had neoplasm in the non peripheral zone. The study suggests the validity of ultrasound, in particularly transrectal ultrasound, in the identification of non palpable prostatic cancer. In conclusion ultrasound appears very useful in the preoperative evaluation of the patients affected by BPH in order to identify neoplasms non detectable with other methods.
