Thoracic wall involvement by Hodgkin disease and non-Hodgkin lymphoma: CT evaluation

Thoracic computed tomographic (CT) scans of 250 patients with newly diagnosed or recurrent lymphoma revealed thoracic wall involvement in 24 patients (11 with Hodgkin disease, 13 with non-Hodgkin lymphoma). Thoracic wall involvement occurred without contiguous mediastinal or parenchymal involvement in 17 patients. Of these, 13 patients had masses beneath the pectoralis muscles or within the breast, and four had masses arising from the ribs. Five additional patients had mediastinal masses with thymic involvement and parasternal extension through the thoracic wall. Pulmonary parenchymal lymphoma with thoracic wall invasion was noted in the remaining two patients. In five of nine patients receiving radiation therapy, treatment plans were modified by CT demonstration of thoracic wall lymphoma.     

Renal pseudoaneurysm after blunt renal trauma in a pediatric patient: management by angiographic embolization

Renal pseudoaneurysm is a rare complication after blunt renal trauma. Only 18 cases have been reported in English-language published reports. We present a case of blunt renal trauma in an 11-year-old boy, complicated by delayed bleeding from a renal artery pseudoaneurysm. The patient was initially treated with conservative measures and was later treated with selective embolization of the pseudoaneurysm. The clinical presentation, management options, and clinical decisions are discussed.     

Laparoscopic dismembered pyeloplasty by a retroperitoneal approach in children

OBJECTIVES: To report our experience with dismembered laparoscopic pyeloplasty by a retroperitoneal approach in children with pelvi-ureteric junction (PUJ) obstruction. PATIENTS AND METHODS: Between 1999 and 2002, retroperitoneal laparoscopic dismembered pyeloplasty was attempted in 21 children (one bilateral; mean age 8 years, range 1.7-17). In a flank position with four ports (one of 5 or 10 mm and three of 3 mm), the PUJ was resected and the anastomosis made using 6/0 absorbable sutures. Any redundant renal pelvis was reduced when needed. A JJ stent was inserted in all patients. RESULTS: The procedure could not be completed by laparoscopy in four patients, the main reason being difficulty in completing the anastomosis; in the other 18 patients the procedure was successful. An aberrant crossing vessel was found in nine patients and dismembered pyeloplasty enabled ureteric transposition in all, with no conversion. The mean (range) operative duration was 228 (170-300) min and the mean hospital stay 2.5 (2-4) days. In three patients the JJ stents were not in the bladder at the time of removal by cystoscopy, and ureteroscopy was used to retrieve them. All children returned to full activities within 7 days of surgery. The mean (range) follow-up was 12.7 (2-36) months, with six children followed for> 2 years; all were asymptomatic, with imaging confirming improved hydronephrosis. CONCLUSIONS: These mid-term results confirm that retroperitoneal laparoscopic dismembered pyeloplasty is a safe and feasible approach in children. Although the technique is very demanding it has the advantage of duplicating the principles of the open approach. The long operative duration and high conversion rate might be reduced with experience. Before expanding this approach to younger children, refinements in the anastomotic technique are needed.     

The predictive value of diagnostic imaging for histological lesions of the upper poles in duplex systems with ureteroceles

OBJECTIVE: To compare the diagnostic imaging findings with the histological lesions in upper pole nephrectomy (UPN) specimens of duplex system ureteroceles, using renal ultrasonography (US) and nuclear renal scintigraphy. PATIENTS AND METHODS: Between 1992 and 2000, 86 patients with a ureterocele in a duplex system underwent surgery. The results from US were reviewed in 84 patients by a radiologist, for echogenicity, parenchymal thinning and hydronephrosis; 77 nuclear renal scans describing the differential function of the upper poles were also reviewed. Fifty-five patients underwent UPN (25 antenatal, 30 postnatal; 18 intravesical, 37 extravesical) and the specimens were available for independent review by a pathologist, describing five histological categories, i.e. chronic interstitial inflammation, fibrosis, tubular atrophy, glomerulosclerosis and dysplasia. Histological lesions were categorized as severe (> 25%) or minimal (相似文献   

The use of tolterodine in children after oxybutynin failure

OBJECTIVE: To assess the safety and efficacy of tolterodine tartrate prescribed to children who previously failed to tolerate oxybutynin chloride. PATIENTS AND METHODS: We reviewed 34 children, followed for>1 year, who were prospectively crossed-over from oxybutynin to tolterodine because of side-effects. The initial diagnosis was dysfunctional voiding in 31 patients. All patients were placed on a behavioural modification protocol. When their symptoms did not improve after 6 months, treatment with an anticholinergic agent was considered. Urodynamic studies were conducted in 20 patients, confirming uninhibited contractions in 19. The remaining 14 patients were empirically started on antimuscarinic or anticholinergic agents. The 34 patients were treated with oxybutynin for a median (range) of 6 (2-84) months. When significant side-effects were reported, they were crossed over to tolterodine. The efficacy of tolterodine was assessed as defined by the International Children's Continence Society, with tolerability assessed and side-effects documented using a questionnaire. RESULTS: The mean age at the first dose of tolterodine was 8.9 years; the dose was 1 mg twice daily for 12 patients and 2 mg twice daily for 22. The median treatment with tolterodine was 11.5 months, with 20 (59%) patients reporting no side-effects; six described the same but tolerable side-effects as with oxybutynin. Eight patients discontinued tolterodine because of side-effects after a median (range) of 5 (1-11) months. The efficacy of tolterodine was comparable with that of oxybutynin, as reported by the questionnaire and voiding diaries. The reduction in wetting episodes at 1 year was> 90% in 23 (68%), more than half in five and less than half (or failure) in six patients. CONCLUSION: Tolterodine is tolerated well in children. In this subgroup of patients who could not tolerate oxybutynin, 77% were able to continue tolterodine treatment with no significant side-effects.
