Review Case ReportsBilateral osteomyelitis due to intraosseous infusion: case report and review of the English-language literature.
Intraosseous infusion, a mode of peripheral access largely abandoned in the 1940s and 1950s, is becoming increasingly popular in the setting of pediatric crisis. While complications are rare when the procedure is properly performed, the risk of osteomyelitis increases with prolonged infusions. We present a case of bilateral osteomyelitis secondary to intraosseous infusion.

Evaluation of prenatally diagnosed hydronephrosis by morphometric measurements of the kidney.
A large number of hydronephrotic kidneys (108) were diagnosed prenatally in 69 infants between 1987 and 1991 and subsequently confirmed postnatally. Prenatal morphometric measurements were done in order to find reliable parameters for the detection of a group at risk for surgical treatment. A second aim of the study was to describe the natural history and management of hydronephrosis detected prenatally. ⋯ Accordingly, we classified the patients as having mild, moderate or severe hydronephrosis. A renal pelvic antero-posterior diameter (APD) of 9 mm or more, and a pelvic-to-renal APD ratio of 0.45 before 32 weeks of gestation and 0.52 thereafter, were found to be useful for the detection of severe outcome. Our new parameter, a pelvic-to-renal volume ratio of greater than 0.08, can also be used for this purpose.

Plain abdominal radiography in suspected intussusception: a reassessment.
The objectives of the study were (1) to determine the interobserver variation in interpretation of abdominal radiographs in children with clinically suspected intussusception, and (2) to determine the diagnostic value of abdominal radiographs in these patients. One hundred and eighty-two plain abdominal radiographic examinations (AXR) performed in children with clinically suspected intussusception were reviewed blind to the clinical history and findings of air enema. The presence or absence of nine AXR signs relevant to intussusception was documented. ⋯ Cecal feces predicted against intussusception, likelihood ratio 0.11. AXR was equivocal in 53%, positive in 21% and negative in 26%. Where a firm radiographic diagnosis was made, the diagnostic accuracy of AXR was 84%.(ABSTRACT TRUNCATED AT 250 WORDS)

Diaphragmatic paralysis in children: diagnosis by TM-mode ultrasound.
Diaphragmatic paralysis, a difficult diagnosis in the pediatric age group, has classically been made by fluoroscopy or B-mode ultrasound. We report our experience with TM-mode exploration. Twenty-seven patients suspected to have diaphragmatic paralysis were examined by means of inspiratory and expiratory chest radiography, fluoroscopy and B-mode ultrasound. ⋯ It can identify direction of the movement even if they are fast and of weak amplitude and in the case of bilateral paralysis. TM can differentiate paralysis from dysfunction. Moreover, this low-cost, non-irradiating made of imaging can be performed at the bedside and is available on all basic devices.

Case ReportsCavitary pulmonary lesions in type IV Ehlers-Danlos syndrome.
Type IV Ehlers-Danlos syndrome (EDS) is characterized by large vessel bleeding, visceral rupture and early death. Pulmonary complications are uncommon. We report an 18-year-old patient with EDS type IV who developed recurrent large, thick-walled lung cavitary lesions, probably a manifestation of focal lung rupture. Such hemorrhagic cavities are probably the basis of the bullous disease and recurrent pneumothoraces occasionally observed in type IV EDS.
