[Menkes disease. Report of a case with pronounced involvement of connective tissues and changes in epidermal desmosomes].

The authors describe a patient who presented from birth on a severe involvement of connective tissues with pathological fractures, lack of auricular cartilage, hyperlaxity of fingers and cutis laxa with deep folds, all suggestive of derangements of collagen and elastin. Hypothermia at 24 hours of age should have already indicated the possibility of Menkes' syndrome. From the 3rd month on, the patient presents a neurological deterioration and a myoclonic epilepsy which is resistant to treatment. Craniocerebral tomodensitometry revealed, with time, a cerebral atrophy and subdural hematomas. Angiodysplasia of a coronary artery was seen at cardiac echocardiography. Undetectable levels of serum copper and ceruloplasmin, and an increased uptake of copper by fibroblasts in vitro confirmed the diagnosis of Menkes' syndrome. Electron microscopy of a skin biopsy disclosed a desmosomal anomaly in the epidermis. Desmosomes stay apart suggesting an alteration of the interdesmosomal cement.

[Computerized retrospective study of 141 children operated on for vesico-ureteral reflux].

Follow-up study of 141 cases of vesico-ureteric reflux (less than 10 years old) treated by Cohen's method. Computerized study, 5 years after treatment, with analysis of the influence of different parameters (type of VUR, age, sex, urinary infection or not, space of time between diagnosis and treatment) on the renal parenchymal radiographic measurements ( Hodson 's method). The youngest is the child when he is treated, the best is the functional result.

[Urinary infections following bladder catheterization].

The incidence and the prophylaxis of urinary tract infection following bladder catheterization have been studied in 142 patients admitted for voiding cystourethrography (VCU). 71 children received a prophylactic treatment of 2 mg/kg nitrofurantoin daily for 4 days, while 71 received no treatment following bladder catheterization. Bacteriologic examination of the urine 4-9 days after catheterization showed significant bacteriuria in 5 untreated children. The germs responsible were E. coli, Proteus, and Klebsiella. None of the treated patients presented with significant bacteriuria. It is concluded that the incidence of significant bacteriuria after a VCU is not inconsiderable, that this urinary tract infection is often asymptomatic, and that the prophylactic administration of a disinfectant is justified.

Appendiceal abscess. A challenge in abdominal masses in children.

In children, more frequently than in adults, appendicitis is complicated by abscess formation. Facing an abdominal mass, especially if it is in the lower abdomen, the radiologist should consider tumor formation, teratoma, malformation or abscess. If there is air within the mass, the diagnosis of abscess is likely; if there is a stercolith, the diagnosis of perforated appendicitis has to be made.
