Kidney transplantation in children weighing less than 15 kg: extraperitoneal surgical access-experience with 62 cases

Small children are a challenging group in whom to perform KT. This retrospective study analyzed the results of 62 KTs in children weighing <15 kg, performed between 1998 and 2010, using extraperitoneal access and anastomosis of the renal vessels of donors to the aorta and IVC or iliac vessels of the recipients. Thirty-two (51.6%) grafts were LRDTs and 30 (48.4%) were DDRTs-28 of them pediatric. The mean age at KT was 3.7 ± 2.2 yr (1-12), and the mean weight was 12.3 ± 2.1 kg (5.6-14.9). Ten children weighed <10 kg, and five (8.1%) children presented previous thrombosis of the venous system. At one and five yr, patient survival was 93.2% and 84.2%, and graft survival was 85.2% and 72.7%. There were no differences between the rates for LRDT and DDRT. There were six vascular complications (four vascular thromboses, one laceration, and one renal artery stenosis) and two perirenal collections. Extraperitoneal access is a valid KT technique in children weighing <15 kg.

Efficacy evaluation of educational sessions for patients with asthma and COPD

INTRODUCTION

Asthma and COPD are respiratory diseases in which a better knowledge and understanding of the pathology allows the patients to be more involved, which is crucial in their treatment. Holding educational sessions is a good way of imparting information to the patients.

AIM

To determine the efficacy of educational sessions in helping patients with Asthma and COPD to acquire a better understanding of their condition.

METHODS

Following a Portuguese Lung Foundation initiative to improve knowledge about respiratory health, educational sessions for patients suffering from Asthma or COPD were organized. 25 randomized patients with the disease were invited to participate. Each session lasted 60 minutes. Patient knowledge was tested by means of a multiple choice questionnaire before and after the session.

RESULTS

Fifteen patients with asthma attended the sessions, they had an average age of 36 years, of which 60% were female. Within the group 60% were able to name their pathology correctly. Seventeen patients with COPD attended the sessions, they had an average age of 69 years, of which 70% were males and only 3 (17,6%) patients were able to correctly name their pathology. In both groups, there was a statistically positive improvement (p<0,05) of correct answers to the questionnaire the end of each educational session.

CONCLUSION

Patient knowledge increased in each educational session. Patients with COPD were less well informed about their disease than patients with asthma and they also had more difficulty in correctly naming their disease.

Hemoptysis--etiology, evaluation and treatment in a university hospital

OBJECTIVE

Evaluate patients admitted for hemoptysis, its etiology, use of diagnostic tests, treatment and outcome.

METHODS

A retrospective analysis was done, checking clinical files of patients admitted for hemoptysis, between 1st January 2004 and 31st December 2008.

RESULTS

Two hundred and thirty seven patients were included in this study, with a mean age of 57.9 years. In patients under 18 years, the most frequent diagnoses were Bronchiectasis and Congenital Cardiopathy. In adults, Pulmonary Tuberculosis Sequelae and Bronchiectasis were the dominant diagnoses (22.2 % and 15.8 %, respectively), followed by Lung Cancer. Active infection was responsible for bleeding in 51 patients, especially Pulmonary Tuberculosis, Pneumonia and Tracheobronchitis. The etiology of hemoptysis was not established in 6.3 %. All patients performed chest X-Ray. Chest CT was performed in 81.4 % of patients and Fiberoptic bronchoscopy in 52.7 %, the latter locating the source of bleeding in 38.4 % and establishing a final diagnosis in 17.6 %. In most patients, effective control of bleeding was achieved by medical treatment (90.7 %). During these 5 years, arterial embolization was performed in 11.8 % of patients. The main reason for embolization was recurrence prevention. There were 14 deaths (5.9 %), being identified as poor prognostic factors, hemodynamic instability and malignancy.

CONCLUSION

Hemoptysis is still a frequent symptom, being chronic infection sequelae and lung cancer their main causes. In this study, factors associated with a worse prognosis were hemodynamic instability and malignancy.

Results of En Bloc Renal Transplants of Pediatric Deceased Donors into Adult Recipients

Various strategies have evolved to expand the donor pool due to the extreme shortage of organs. Herein we reviewed our experience with en bloc pediatric kidney transplantation since 1998.

METHODS

From January 1998 to December 2004, nine adult patients underwent kidney transplantation using en bloc kidneys from donors <5 years old (range, 1 to 4). The mean age of the recipients was 45.1 years (range, 34 to 57).

RESULTS

In recipients of en bloc pediatric transplantation, cold ischemia time ranged from 14 to 26.2 hours (mean, 21.3 hours). Mean serum creatinine at 3, 6, and 12 months after transplantation was 1.53 +/- 0.57, 1.27 +/- 0.27, and 1.15 +/- 0.26 mg/dL compared with 1.93 +/- 1.35, 1.81 +/- 1.17, and 1.73 +/- 0.85 (P = .08) in recipients of single kidneys from ideal cadaveric donors (UNOS criteria, n = 368). Patient and graft survival at 1 year were 88.8% compared with 91.2% and 85% with ideal donors (P = NS), respectively. Three cases required additional surgery. There was one death due to a cerebral vascular accident.

CONCLUSION

The present study confirmed the excellent results achieved with transplantation using en bloc kidneys from young donors.
