Caspofungin associated with liposomal amphotericin B or voriconazole for treatment of refractory fungal pneumonia in children with acute leukaemia or undergoing allogeneic bone marrow transplant.

Caspofungin, in association with other antifungal drugs, was administered as rescue therapy in two cases of documented and one case of possible invasive fungal infection in children with acute leukaemia or undergoing allogeneic bone marrow transplant. The combined therapy was well-tolerated and seemed to be effective in all three patients. A combination antifungal therapy including caspofungin could represent an effective therapy for children with invasive mycoses refractory to single-agent antifungal therapy.

Vesical continence in bilateral ectopic single ureters.

PURPOSE: We explore the possibility of gaining suitable vesical capacity and continence in bilateral single ureters without having to resort to urinary diversion or bladder neck reconstruction. MATERIALS AND METHODS: In the last 10 years we treated 6 girls with bilateral ectopic ureters, and 2 with a single kidney and urethral ectopic ureter. Both ureters were ectopic in the urethra in 3 cases, and 1 ureter was inserted in the urethra and 1 in the bladder neck in the other 3. Preoperative examinations included ultrasonography, cystography, excretory urography and endoscopy in all cases, and magnetic resonance imaging in 2. Patient age at intervention ranged from 1 month to 8 years. RESULTS: Cross-trigonal reimplantation of the ectopic ureters through a correctly positioned neomeatus was performed in 7 cases. In 2 patients it was impossible to reach the ureteral insertion from inside the bladder (1 ureter in 1 and both ureters in 1), and so the distal tract of these ureters was resected extravesically as close as possible to the urethra. One patient with a single kidney also had an anorectal malformation and a rectovaginal fistula. She had pelvic renal ectopia and the ureter was inserted beneath the urogenital diaphragm causing minimal bladder capacity. Therefore, a sigmoid neobladder with appendicostomy was constructed according to the Mitrofanoff principle. A Young-Dees bladder neck plasty was done in 2 patients at the same time as ureteral reimplantation and 3 years later in 1. Followup urodynamics revealed more than acceptable continence. Bladder capacity was insufficient in only 1 polyuric patient. CONCLUSIONS: A bladder with bilateral ureteral ectopia is not necessarily useless, and the majority of patients can achieve normal bladder function and capacity along with normal transurethral voiding and satisfactory continence.

Total colectomy and straight ileo-anal soave endorectal pull-through: personal experience with 42 cases.

During the period from 1974 to June 2000 we used the straight ileo-anal Soave pull-through to treat 42 patients (24 affected by total colonic aganglionosis [TCA], 10 with ulcerative colitis and 8 with familial polyposis). The aim of this paper is to show that this operation, associated with total colectomy, is highly recommended, causing a lower number of complications when compared to the various "reservoir" techniques. The mean age of the 24 patients with TCA at the time of the pull-through was 2.8 years; in the ulcerative colitis group, it was 14.3 years and in the familial polyposis group 27.2 years. We always used an ileo-anal deferred anastomosis and never performed temporary loop-diverting ileostomy at the time of the pull-through. In the TCA patients we had no immediate or long-term serious post-operative complications: ileal adaptation, after a frequency of 10 - 12 liquid stools a day, showed a gradual, constant and in some cases amazing improvement in all children. Two years after surgery, the mean stool frequency was 3.6 per 24 hours with no significant differences between the 3 main groups; only 4 children still presented with occasional soiling. After pull-through, all children showed normal growth curves in the long term. There was no malabsorption, no serious electrolyte imbalance, no perianal excoriation, no strictures or intestinal obstruction; their quality of life was considered more than satisfactory by the children's families. We have no direct experience with the various ileal "reservoir" techniques for ulcerative colitis and ileal polyposis nor with colon-sparing operations for TCA; as reported in the literature, all these surgical procedures seem to have a higher number of complications such as pelvic sepsis, pouchitis, enterocolitis, etc. compared with our series; we therefore confirm that total colectomy with the straight ileo-anal Soave pull-through is our treatment of choice, as it is simpler to perform and has fewer short- and long-term complications.

Treatment of vesico-ureteric reflux in children with neuropathic bladder: a comparison of surgical and endoscopic correction.

BACKGROUND/PURPOSE: Vesico-ureteric reflux (VUR) is a common problem in children with neuropathic bladder. Lesser-degree VUR may be manageable by intermittent catheterization or by anticholinergics, but higher grades usually require surgical treatment. If left untreated, two thirds of such patients may experience deterioration of the upper renal tracts. The aim of this study was to compare the results of the STING (Subureteric Teflon Injection) technique with surgical ureteric reimplantation as treatment for VUR in neuropathic bladder. METHODS: From January 1981 to December 1996, 58 children with NB (81 ureters) were treated for VUR. STING and Cohen ureteroneocystotomy were performed in 40 and 41 ureters, respectively. Mean age was 4.5 years (STING) and 5.1 years (Cohen). RESULTS: Twenty-nine of 40 refluxing ureters (72.5%) were cured by STING, whereas Cohen eradicated reflux in 39 of 41 ureters (95.5%). No complications were observed in either group. All the ureters in which STING failed were treated successfully by Cohen ureteroneocystostomy. The 2 ureters still refluxing after surgical reimplantation were cured successfully by a single STING. The mean follow-up was 6.8 years in the Cohen group and 4.8 years in the STING group. During follow-up, no recurrence was observed in patients cured by open reimplantation. In the STING group, 2 previously cured ureters showed recurrence of VUR: both were treated successfully by a further STING. CONCLUSIONS: Open ureteral reimplantation is more effective than STING in correcting VUR in children with neuropathic bladder dysfunction. Nevertheless, the good success rate, the relative technical simplicity, outpatient nature, and rapid recovery point to STING as a safe and effective procedure for the initial treatment of VUR. Failure of STING does not preclude a successful open operation.

Follicular cell carcinoma of the thyroid in a child after bone marrow transplantation for acute lymphoblastic leukemia.

Follicular cell carcinoma (FCC) of the thyroid is rarely found during childhood. We report a 12 1/2-year-old girl with acute lymphoblastic leukemia, who developed rapidly growing FCC of the thyroid, 3 years after bone marrow transplantation. The role of chemotherapy in the induction of such secondary tumors after transplantation is discussed, and a proposal for the approach to these patients is suggested.

New concepts in preoperative imaging of anorectal malformation. New concepts in imaging of ARM.

In this study of 14 patients with anorectal anomalies CT and MRI were employed for preoperative assessment. The use of a pressure enhanced water soluble enema via the colostomy proved to be an extremely efficient method for showing a fistula. MRI studies were enhanced by the use of vaseline oil and in one case this technique was used prior to surgery to provide important information by injecting through a perineal fistula. CT and axial MRI proved to be more valuable than sagittal MRI which is only useful for the length of the atretic segment. The authors consider that a combined approach using pressure enhanced water soluble enema and MRI will provide the most valuable preoperative information to plan a successful operative approach and enable an accurate prognostic evaluation of continence in these difficult and complex patients.

Intraabdominal calcifications in the newborn: an unusual case with anorectal malformation and other anomalies.

Intraabdominal calcifications are an unusual radiographic finding in the newborn and can easily be misinterpreted as meconium peritonitis. The authors refer to a patient with anorectal malformation (ARM), intraluminal calcifications and other anomalies. Careful differentiation of the type of intraabdominal calcifications can suggest the possibility of other initially unsuspected anomalies.

Leiomyomatosis of oesophagus, congenital cataracts and hematuria. Report of a case with rectal involvement.

Isolated oesophageal leiomyomatosis in children is very rare. The association between leiomyomatosis of oesophagus and female genital tract and an Alport like hematuric nephritis has been recognized as a distinct entity by Garcia-Torres and Guarner. Since then few other cases of this syndrome have been observed. Congenital cataracts and neurosensory deafness have been added to the clinical spectrum. Autosomal dominant inheritance is suggested by the familial cases. We report a patient who presents, as a new finding, leiomyomatosis of the rectum.

[Blocked transcolostomy colonography in the identification of anorectal malformations].

The study of anorectal malformations has considerably improved over the last years also thanks to the use of such diagnostic techniques as CT and MR imaging, which allow a better knowledge of perineal region anatomy and the demonstration of the development of sphincteric structures. The most important diagnostic phase for the identification of anorectal malformations consists in the detection of rectal fistulas. The authors report on their experience with barred water-soluble contrast enema in the study of anorectal anomalies. Over 2 years, 23 patients with anorectal malformations (10 males and 13 females) previously submitted to colostomy, were studied with this method. Fistulas were detected in 21 cases; in the extant 2 patients (both females affected with Down syndrome), no fistulas were detected, not even at surgery, which was posterior sagittal anorectoplasty according to Peña-De Vries. In our experience, the most frequent anomalies were recto-bulbo-urethral fistula in males and low recto-vaginal fistula in females. The authors suggest the use of this method as a routine diagnostic examination, because of its proven reliability.

[Computed tomography vs. magnetic resonance in the diagnosis of anorectal anomalies].

Anorectal malformations include a variety of anatomical anomalies which are often difficult to assess. Thirty-four patients (age range: 1 month-19 years) were studied over a 4-year period, 14 of them preoperatively and 20 postoperatively. In addition to inverted lateral plain films, a barred Iopamiro enema was performed in 13 of 14 cases by a Foley's catheter via colostomy. Endocolic pressure could thus be increased, which allowed the detection of rectal fistulas in 11 of 13 cases. Preoperative CT was performed in 9 cases, and MRI in 5. Both CT and axial MR scans provided accurate images of sphincteric muscles: they were well developed in 7 patients and poorly developed in 6; in 1 case the muscles were not identified. Sagittal MR scans only demonstrated the distance between blind pouch and perineum. Sagittal MRI also provided images of the spine (1 patient exhibited tethered cord). In the postoperative management, except for severe sacral anomalies, miscentered puborectal muscle and hypoplastic musculature were observed as the most frequent causes of fecal incontinence in patients treated with abdomino-perineal pull-through of the colon. To select the cases who needed reoperation, most frequently secondary PSARP, 17 patients were studied by CT and 7 by MRI; both techniques were employed in 4 cases. In 6 patients good development of sphincteric musculature and neo-anorectum correctly positioned within were observed. In 4 cases the neo-anorectum was correctly positioned, but sphincteric muscles were too hypoplastic to allow good continence; in 10 patients with incontinence, the neo-anorectum was seen outside sphincteric musculature: in 2 cases the latter was well developed (1 patient had had severe surgical damage to levator ani), while in 8 it appeared to be poorly developed. In our experience, postoperative CT allowed a correct evaluation to be made, whereas MRI failed to yield additional information.

[Axial computed tomography in anorectal malformations: a pre- and postoperative indication?].

Ten patients with anorectal malformations were studied by preoperative CT: well developed sphincteric muscular structures (puborectal sling of levator ani, muscular striated complex and external sphincter) were present in six patients. In three patients muscular structures were poorly developed (case 2a with rectovaginal fistula, case 5a with rectocloacal fistula and case 7a with prostatic fistula). In one case with bladder fistula, the sphincteric musculature was not identified at all. Eleven patients were postoperative studied by pelvic CT: Two of 11 cases had a good sphincteric control. The other nine patients were incontinent. In three of the nine incontinent patients, the colon was appropriately place, but puborectal muscle and sphincteric complex were hypoplastic. In the other six cases CT showed a pulled through colon out of the sphincteric structures. Four of them presented major bony sacral abnormalities and/or lesion of the sphincteric muscle structures. The remaining two patients with an evident pulled-through colon out of a normally developed sphincteric region and without sacral anomalies, were selected for a secondary PSARP procedure. In one of these two patients the operation brought about a complete resolution of the fecal incontinence. The pelvic CT is a useful examination in the anorectal malformation for the preoperative prognostic evaluation of continence, while postoperative CT is essential in selecting those incontinent patients who need a secondary PSARP for the treatment of fecal incontinence.
