Cardiopulmonary performances in young children and adolescents born with large abdominal wall defects.

BACKGROUND/PURPOSE: As long as the survival rate of patients with abdominal wall defects (AWD) increases, information about long-term follow-up is becoming necessary. Even though quality of life in these patients, in absence of associated anomalies, appears to be unaffected, respiratory impairment soon after birth has been documented; therefore, participation in sports rarely is addressed. METHODS: Eighteen patients, ranging in age from 7 to 18 years, operated on at birth for large abdominal wall defects (> 4 cm for gastroschisis; >6 cm for omphalocele) were asked to come for a stress test on a treadmill, with measurements of time of exercise (TE), maximal oxygen consumption (VO2 max) and continuous recording of vital parameters. Respiratory function also was assessed by Forced Vital Capacity (FVC). RESULTS: Ergometric data were compared with those of a normal pediatric population. All patients were able to perform the stress test with no cardiovascular abnormalities detected at rest or on exertion. Maximum heart rate was reached after a significantly shorter TE, and VO2 max was significantly reduced when comparing normal subjects with AWD subjects and AWD subjects in sports with those sedentary. FVC was only slightly reduced in AWD patients without reaching statistical significance. CONCLUSIONS: These findings indicate that patients operated on for AWD at birth exhibit a normal cardiorespiratory function; decreased TE and VO2 max are likely to reflect a lack of physical activity with a lower degree of fitness. Therefore, no limitations to motor performances should exist for these patients. Well-being may be greatly improved by regular exercise.

[Does B-mode ultrasound still have a role in the diagnosis of spermatic cord torsion? Findings in a pediatric series].

INTRODUCTION: Acute scrotum in the pediatric age is mainly related to surgical causes. Spermatic cord torsion and inguinoscrotal hernia must be ruled out first, because of the possible ischemic damage to gonadal tissue and therefore surgery is sometimes performed directly, thus representing also a diagnostic tool. Spermatic cord torsion is found in two age ranges, namely: the neonatal period, where it usually represents the evolution of an intrauterine process, and the peripubertal period, which is more frequent. An unquestionable and prompt diagnosis is particularly needed because of the extreme sensitivity of gonadal tissue to ischemia. In this particular field, color and power Doppler US, depicting gonadal flow, have greatly increased diagnostic imaging capabilities, which were previously limited to B-mode US. MATERIAL AND METHODS: We examined 19 peripubertal patients with the diagnosis of spermatic cord torsion made on the basis of B-mode US and then confirmed with color Doppler. RESULTS: We found two signs which can be considered highly suggestive of spermatic cord torsion: the spiral twist of spermatic vessels and the peculiar extent of reactive hydrocele, caused by the bell clapper anomaly of the vaginal sac. CONCLUSIONS: The above US patterns are very helpful to diagnose spermatic cord torsion.

Cranial ultrasonography in maple syrup urine disease.

We performed serial cranial ultrasonography in four newborns affected by maple syrup urine disease. Symmetric increase of echogenicity of periventricular white matter, basal ganglia (mainly pallidi), and thalami was detected in the acute stage. The degree of ultrasonography abnormalities paralleled the clinical course of the disease.

The incidence of occult spinal dysraphism and the onset of neurovesical dysfunction in children with anorectal anomalies.

The urological malformations associated with anorectal anomalies (ARA) are not only anatomical, but also functional, the latter being related to congenital neurovesical dysfunction (NVD). The true incidence of spinal dysraphism (SD) in these children is still unclear and is probably underestimated. The concept of caudal regression could explain its association with the anorectal anomalies. Because of awareness of the late onset of neurovesical dysfunction and/or orthopaedic symptoms in some of our patients, in 1991 we started to screen with magnetic resonance imaging (MRI) the spinal cord of all patients with ARA. Eighteen (44%) out of 41 patients without neurological or orthopaedic symptoms and 7 (78%) of 9 children with neurological or orthopaedics symptoms screened by MRI showed pathological findings. The overall incidence of spinal dysraphism in ARA was 50%, without any great difference with respect to the type of the anomaly (high, low, cloacal). The pathological MRI findings encountered were: fibrolipoma (with or without a thickened filum terminale), tethering of the cord and syringomyelia, and sac anomalies. In order to check the onset of NVD in these children, we performed urodynamic studies with external sphincter electromyography in 24. Grouped by age: 14 were between 5 and 18 months and ten were 4 to 13 years old. Ten patients (71%) out of the first group and 3 (30%) out of the second had a normal urodynamic pattern. A total of 11 children had pathological findings; of these, 4 infants had a hyperreflexic bladder (one with detrusor-sphincter dyssynergia) suggesting upper motor neuron (UMN) lesion. Of the 7 older patients, two had UMN and 3 lower motor neuron (LMN) lesion.(ABSTRACT TRUNCATED AT 250 WORDS)

Renal vein thrombosis and adrenal hemorrhage in the newborn: ultrasound evaluation of 4 cases.

Renal vein thrombosis and adrenal hemorrhage can both be encountered in the neonatal period and they may occur at the same time. Inferior vena cava thrombosis can complicate some cases. These diseases can be easily diagnosed by means of ultrasound. The authors present 4 cases in which newborns were affected by renal vein thrombosis associated with adrenal hemorrhage and caval thrombosis, evaluated by means of ultrasound. The echographic aspect of renal, adrenal and caval involvement is described.
