[Echography in the follow-up of neonatal adrenal hemorrhage. The presentation of 14 cases].

Fourteen cases are reported of monolateral adrenal hemorrhage in newborns who were submitted to US exam at 1 week, 2 weeks, 3 weeks, and 3 months of age. The variability is emphasized of US and pathologic findings according to the patients' age. A concise terminology is suggested allowing the description of morphological and echo-structural patterns in adrenal hemorrhage. Being familiar with US spectrum of neonatal adrenal hemorrhage appearances can provide useful data in the cases with atypical clinical features. Moreover, the differential diagnosis becomes easier of neonatal adrenal hemorrhage and other diseases such as neonatal neuroblastoma, adrenal abscess, cystic neuroblastoma, cortical renal cyst, and obstructed upper cortical renal cyst, and obstructed upper excretory tract in duplicated kidney. The most effective criterion for US differential diagnosis is probably the chronological variability of US findings. Sonography is stressed as an useful and effective imaging modality in the diagnosis and follow-up of adrenal hemorrhage which helps avoid X-ray investigations and unnecessary laparotomies.

[Congenital valves of the ureter. Comments on 7 cases studied in childhood].

Ureteral valves are a rare cause of congenital obstructive uropathy in pediatric age. Symptoms onset is variable and depends directly on the degree of valvular obstruction. Seven cases of ureteral valves were studied in the Radiology Department of "Bambino Gesù" Pediatric Hospital in Rome; every type of technique available in the hospital was employed. For each case, the authors carefully describe the clinico-radiological approach which led to the diagnosis of obstruction due to the presence of one or more valvular structures (hydronephrosis). Intravenous urography proved to be the most sensitive examination to confirm the diagnosis of suspected obstruction made on the basis of US findings, and to assess its precise location. Segmental ascending pyelography was also employed, which consists in cystoscopically inserting a ureteral catheter into the renal pelvis, and then administering a contrast medium which allows the fluoroscopic visualization, both above and below the stricture, of the ureteral segments. The technique also allows the detection of other valves of the same ureter not otherwise recognizable. All 7 patients underwent surgery; follow-up at 12 months demonstrated clinical symptoms regression and a good functional and morphological recovery of the involved ureter.

Is perlaparoscopic bacteriological analysis sufficient for establishing the etiology of P.I.D.?

The Authors have studied the usefulness and the limits of laparoscopy in the etiologic diagnosis of P.I.D.; for this purpose 21 patients affected with P.I.D. underwent microbiological sampling from cervix and/or vagina and from Fallopian tube during laparoscopy. The findings have shown a discrepancy between the microbiological isolation from vagina/endocervix and from salpinx and remarkably the loss of evidence of S.T.D. agents from tuba with, conversely, frequent isolation of these agents (34.7%) from cervical swabs. Therefore, the Authors believe that the percelioscopic microbiologic study of endosalpinx is essential for the correct etiologic diagnosis of P.I.D., especially in anaerobic germ infections; yet the technical problems of percelioscopic samples and the biological features of S.T.D. agents require the simultaneous bacteriological sampling from the cervix and/or vagina.

[Impingement syndrome of the shoulder. Clinical data and radiologic findings].

Subcoracoid impingement syndrome pain is elicited by some positions of the upper limbs, i.e., adduction and inward rotation, whenever coracohumeral space reduces. Although acquired or congenital malformations of the humeral head and/or coracoid apophysis are the most common causes of painful syndromes, repeated flections and inward rotations of the upper limbs, typical of some sports, such as swimming and tennis, and of some sports, such as swimming and tennis, and of some kinds of work, are predisposing factors. The subcoracoid impingement syndrome exhibits on pathogenomonic signs at clinics and the specificity of diagnostic methods is low, which calls for reliable radiologic assessment of this condition. Fifteen patients with subcoracoid impingement syndrome underwent X-ray, US, CT and MR studies. Plain radiography detected no specific signs of this syndrome, but yielded useful information regarding other painful syndromes of the shoulder, such as anatomical variants of the acromion and degenerative changes. US yield was poor because of the acoustic window of the coracoid apophysis, but supraspinatus tendon changes were demonstrated in 2 cases. CT and MRI proved to be the most reliable and accurate diagnostic methods, the former thanks to its sensitivity to even slight bone changes and to its capabilities in measuring coracohumeral distance and acquiring dynamic scans and the latter because it detects tendon, bursa and rotator cuff changes. To conclude, in our opinion, when the subcoracoid impingement syndrome is clinically suspected, plain X-ray films should be performed first and followed by MR scans.

[Diagnosis of gastroesophageal reflux in childhood. Comparison of ultrasonography and barium swallow].

Gastroesophageal reflux (GER) is a very common event in the pediatric patient. An accurate and atraumatic imaging technique must be used to differentiate normal from abnormal conditions. Sonography (US) appears to answer this purpose, as recently shown in the international literature. One hundred and seventy-eight patients with suspected GER were enrolled in this study; their age ranged 10 days to 15 years. They were examined with both US and barium swallow, in a double-blind trial. The patients were divided into three groups, according to GER severity, i.e., absent or physiologic GER, moderate GER and severe GER. We considered not only the number of reflux episodes, as related to patients' age, but also reflux volume, esophagus clearing time and possibly coexisting hiatal hernia or esophagitis. US and barium swallow results were in agreement in 93% of the cases. In the other cases US demonstrated more severe GER than barium meal. No statistically significant differences were observed in the various age groups. Since US is a relatively cost-effective, noninvasive and physiologic method which is widely available and uses no ionizing radiations, it can be recommended as the screening test of choice in symptomatic children and in the follow-up.
