[Necrotizing cellulitis complicating varicella in two children given nonsteroidal anti-inflammatory drugs].

We report two cases of fasciitis with necrotizing hypodermitis of the foot and arm which complicated varicella in immunocompetent children given nonsteroidal anti-inflammatory drugs. The skin barrier and immune function are weakened by the varicella zoster virus. Exposure to nonsteroidal anti-inflammatory drugs further favors necrotizing cutaneous infections caused by group A beta hemolytic streptococci. MRI can confirm the presence of superficial aponevrosis necrosis defining necrotizing fasciitis but should not retard surgical management which is always indicated for necrotizing fasciitis and sometimes for necrotizing dermo-hypodermitis.

[Kidney trauma in children: state of the art medical imaging].

Traumatic renal lesions have some particularities in the pediatric age group, especially for anatomic reasons. Imaging is very important for diagnosis and staging. Ultrasonography with Doppler is the first line examination performed in children and frequently allows initial diagnosis. From the Doppler-ultrasonographic results and the type of trauma, renal Computed Tomography (CT) is complementary performed. The association of these imaging techniques allows comprehensive work-up of traumatic renal lesions, and also of associated or pre-existing lesions. Conservative management is the rule in most cases. Interventional imaging techniques are sometimes used for therapeutic care of renal pedicular vascular lesions or lesions of the collecting system. Far from the traumatic event, imaging allows to follow up the morphologic and functional evolution of major renal lesions, in particular lesions of excretory renal ducts.

[Reliability of the Sauvegrain and Nahum method to assess bone age in a contemporary population].

PURPOSE: The Sauvegrain and Nahum method can be used to assess bone age in addition to methods based on hand and wrist radiographs in children between 9 and 15 years of age. The aim of this study was to evaluate the reliability of this method in a contemporary population. MATERIAL AND METHODS: Elbow radiographs taken for acute trauma in 106 patients (42 girls, 64 boys) aged from 9 to 15 years old were analyzed by four radiologists. Inclusion in the study required the absence of chronic disease and previous trauma as well as parental consent. RESULTS: There was no significant difference between the four observers. The differences between bone age (BA) and chronological age (CA) were 5+/-1 months for the study group, 3.5+/-9 months for the female group, and 6+/-12 months for the male group. Bone age was overestimated compared with chronological age. There was a good correlation between CA and BA (r = 0.84). CONCLUSION: The Sauvegrain and Nahum method seems to overestimate CA in a contemporary population.

[Prenatal MRI diagnosis of esophageal atresia].

The diagnosis of esophageal atresia may be suspected on prenatal ultrasonography in fetuses with absent or small stomach, upper esophageal dilatation and unexplained polyhydramnios. However, the diagnostic value of these findings is relatively poor. Two cases are reported where MRI appeared to be accurate for establishing the diagnosis of this congenital anomaly.

[Prenatal screening of kidney pelvis ectasia, frequently caused by vesico-ureteral reflux detected after birth. Analysis of a series of 159 cases in 4 years at a maternal-child unit].

UNLABELLED: To describe the pre- and post-natal management of vesico-ureteric reflux in a prospective study of babies presenting with vesico-ureteric reflux suspected from pre-natal ultrasonography in a tertiary paediatric center. PATIENTS AND METHODS: Between 1997 and 2001, 35 children (25 boys and 10 girls) with were vesico-ureteric reflux followed for 12 to 36 months after the pre-natal detection of urinary tract anomalies. Ultrasound examination was realized at the 5th of life, retrograde cystography at the 15th if the renal pelvic dilatation measured at least 10 mm of diameter. In 11 the reflux was bilateral and 46 refluxing units were reviewed. RESULTS: According to the international classification of, 7% vesico-ureteric reflux were grade I, 20.5% were grade II, 32% were grade III, 18% were grade IV, 22.5% were grade V. Fourteen patients (17 refluxing units) underwent ureteric-reimplantation. Four total and two partial nephrectomics were carried out in patients < 2 years old; in 8 patients the VUR resolved spontaneously. Of the latter, 7 patients (ten refluxing grade III-IV units) are still being followed and awaiting a decision on treatment. CONCLUSION: This study confirms the predominance of boys in those with antenatally suspected vesico-ureteric reflux. The spontaneous resolution or improvement during the first 3 years of life was apparent in most cases, even in those with severe reflux (grade III-V).

[Appendix-ureteroplasty in a child: report of a case].

The use of vermiform appendix as a tube to replace right ureteral segment has been reported, rarely in child. Herein is reported a case of right ischemic ureteral stenosis following a reimplantation of the ureter for high grade reflux secondary to posterior urethral valves with only one functioning kidney. A long ureteral defect was bridged successfully by appendix interposition and then reimplanted in the bladder at four years of age. The interest of ureteroappendiculoplasty provides temporary solution to repair long ureteral defect, in spite of uncertain future, especially in childhood.

[Strategies diagnosis of polytraumatized adult patients with coma].

OBJECTIVE: To review the diagnostic strategy of management of multiple trauma patient during the first hours. DATA SOURCES: Extraction from Pubmed database of French and English articles on the management of multiple trauma patient published for ten years. DATA SELECTION: The collected articles were reviewed and selected according to their quality and originality. The more recent data were selected. DATA SYNTHESIS: The first hours of management of multiple trauma patients are a particular challenge. The first dilemma is to drive the patient toward an adequate structure. In case of poor haemodynamic tolerance, the patient will be drive in the nearest hospital. When haemodynamic parameters are restored, multiple trauma patient has to be receive in a high level hospital by a trained medical team with an anesthesiologist, intensivist, neurosurgeon, general surgeon and radiologist. The initial assessment may have two priorities: quality and speed. The total body CT scan is actually the answer to these priorities.

[Pre- and postnatal diagnosis of omphalo-xiphopagus conjoined twins].

We report a case with successful surgical separation of female omphalo-xiphopagus conjoined twins. Ultrasonographic examination at 20 weeks of gestation showed twins joined at the abdomen from the xiphoid process to the umbilicus. Conjoined structures included liver. Karyotype was normal. The parents refused interruption of the pregnancy. Plain films, US and MRI confirmed findings at prenatal ultrasound examination. There was no cross circulation into the livers and the gastrointestinal tract was not conjoined. In our observation, postnatal MRI did not offer additional information.

[CT imaging of pelvic injuries in polytrauma patients].

CT has become a major tool in the management of multiple trauma. Concerning pelvic trauma, visceral and bone injuries can be detected. We review here the different pelvic injuries focusing on CT diagnostic approach.

[Tracheal agenesis: CT diagnosis].

Tracheal agenesis is an exceptional congenital malformation of the airway with fatal consequences. A case of a newborn infant presenting with respiratory distress is reported. Laryngoscopy and helical CT of the airway confirmed the diagnosis of tracheal agenesis with tracheo-esophageal fistula and laryngeal agenesis.
