RESUMO

PURPOSE: To review demographics, effect of preoperative chemotherapy on tumour thrombus, imaging, operative strategy, and outcomes of 12 patients presenting with intracardiac extension of Wilms tumour thrombus. METHODS: A retrospective audit was undertaken on patients with intracardiac extension of Wilms tumour. Patients were identified from the oncology database and information obtained on clinical presentation, stage, preoperative treatment, surgical procedures and complications, histology, and survival status. Ethics approval was obtained from the University of Cape Town Human Research Ethics Committee. RESULTS: From 1984 to 2016, 337 children with Wilms tumour were treated. Twelve (3.6%) had intracardiac extension of tumour thrombus, nine into the right atrium, and three into the right ventricle. Ultrasound, computerized tomography, magnetic resonance imaging, and echocardiograms were used to assess thrombus level. Patients were staged as stage III(8) and IV(4). All patients received preoperative chemotherapy. Thrombus retracted from the heart in two cases. One patient died preoperatively. Eleven underwent laparotomy, median sternotomy, and cardiopulmonary bypass (CPB). Four underwent cavectomy. Five required cavoatrial patches. Thrombus extending into the hepatic veins was extracted in five patients. There was one intraoperative complication and one perioperative death. Thrombus histology showed viable tumour in 9 of 11 patients. Three patients died of progressive disease. Seven patients are currently disease free. CONCLUSION: A combination of imaging is required to determine thrombus extent, and this facilitates surgical planning. Preoperative chemotherapy may cause thrombus regression, thus avoiding CPB. CPB offers appropriate conditions for safe tumour thrombus excision. Full management in centres with appropriately experienced staff and facilities for CPB is recommended.

RESUMO

PURPOSE: This study was undertaken to investigate the types of anorectal malformations (ARM), incidence of associated abnormalities and investigative methods used in patients treated at Red Cross War Memorial Children's Hospital and to determine whether these are in keeping with recent literature. Mortality rates were also reviewed. METHODS: A retrospective review of patients with ARM between 1993 and 2016 was undertaken. Clinical notes were reviewed and correlated with radiology and cardiac databases. Abnormalities were grouped according to genitourinary, musculoskeletal, gastrointestinal and cardiovascular systems. The data were separated into three periods to ascertain whether the workup strategy had changed over the years. RESULTS: A total of 282 patients were included. There were 134 (47.5%) high and 116 (41.1%) low lesions and unspecified in 32 (11.3%) patients. There were 59 (20.9%) vestibular fistulae, 46 (16.3%) combined rectourethral fistulae (rectoprostatic, rectobulbar and unspecified rectourethral) and 42 (14.9%) perineal fistulae. Associated abnormalities were detected in 152/221 (69%). Abnormalities were: Genitourinary 88/204 (43.1%), musculoskeletal 80/188 (42.5%), cardiac 44/218 (20.1%) and gastrointestinal 12/216 (5.6%). Twenty patients demised. CONCLUSION: Vestibular fistulae were most common followed by rectourethral and perineal fistulae. Musculoskeletal and genitourinary abnormalities were the most common associated findings. The mortality rate was 7% and cardiac lesions contributed to mortality. As knowledge of ARM improved, so has awareness of associated malformations. This has led to improved, more active workup, in keeping with the latest literature.

RESUMO

INTRODUCTION: Local anesthetic wound infusion has shown promising results in adults. Its use in children is limited to some centers and there are only a few prospective trials in this group of patients. METHODS: Sub-fascial continuous local anaesthetic wound infusion (CLAWI) (0.2% Bupivacaine) plus intravenous paracetamol and rescue intravenous morphine was compared to: (a) Epidural bupivacaine (EPI) plus paracetamol and rescue intravenous morphine for patients undergoing laparotomy. (b) Intravenous morphine and paracetamol (standard post-operative analgesia-SAPA) in children undergoing Lanz incision laparotomy for complicated appendicitis. 'InfiltralLong', PANJUNK(®) catheters were placed sub-fascially after peritoneal closure for post-operative bupivacaine infusion. Pain scores were recorded regularly by the same blinded pain specialist. The primary outcomes were pain control and total morphine. The secondary outcomes were time to full feeds, mobilization requirement for urinary catheter and complications. RESULTS: Sixty patients (18 laparotomy-CLAWI, 17 laparotomy-EPI and 12 appendectomy-CLAWI, and 13 appendectomy-SAPA) were analyzed. The average pain score was 2.5 (1-4) in the CLAWI groups, 3.0 (1-5) in the EPI group and 3.5 (2-5) in the SAPA group. Morphine requirements were markedly less for CLAWI. SAPA and EPI groups required urinary catheters for longer and took longer to mobilize (average 4 days compared to 2 days for CLAWI). There were no wound or bupivacaine complications in the CLAWI group. CONCLUSION: Continuous subfascial bupivacaine infusion is reliable, safe and effective in paediatric post-operative pain control with considerably reduced opiate requirements.

RESUMO

Burn injuries in Africa are common with between 300,000 and 17.5 million children under 5 years sustaining burn injuries annually, resulting in a high estimated fatality rate. These burns are largely environmentally conditioned and therefore preventable. The Western Cape Province in South Africa can be regarded as a prototype of paediatric burns seen on the continent, with large numbers, high morbidity and mortality rates and an area inclusive of all factors contributing to this extraordinary burden of injury. Most of the mechanisms to prevent burns are not easily modified due to the restraint of low socio-economic homes, overcrowding, unsafe appliances, multiple and complex daily demands on families and multiple psycho-social stressors. Children <4 years are at highest risk of burns with an average annual rate of 6.0/10,000 child-years. Burn care in South Africa is predominantly emergency driven and variable in terms of organization, clinical management, facilities and staffing. Various treatment strategies were introduced. The management of HIV positive children poses a problem, as well as the conflict of achieving equity of burn care for all children. Without alleviating poverty, developing minimum standards for housing, burn education, safe appliances and legislation, we will not be able to reduce the "curse of poor people" and will continue to treat the consequences.

RESUMO

PURPOSE: Intussusception is a recognised but unusual presenting feature of Burkitt lymphoma. We sought to identify the clinical features associated with intussusception in this setting, and assess the outcome following protocol directed chemotherapy. METHODS: A retrospective case note review was performed on patients treated for Burkitt lymphoma at our institution between 1976 and 2010. Cases presenting with intussusception were identified from hospital records and oncology database. RESULTS: Fourteen of the 210 children seen with a diagnosis of Burkitt lymphoma during the study period (6.7%) developed intussusception. Median age was 6.1 years (range 2.5-10.9). Twelve patients presented with recurrent abdominal pain, and two patients with a jaw mass associated with endemic Burkitt lymphoma. Nine patients underwent a right hemicolectomy with ileo-colic anastomosis, and five had segmental small-bowel resections. Three patients had bone marrow involvement at diagnosis, two of whom died. All patients received chemotherapy. Median follow-up was 6.07 years (range 0.1-28.8). CONCLUSIONS: Small bowel lymphoma should be considered in children presenting with intussusception above the normal infantile peak age range. The presentation is often insidious, and complete obstruction may not be apparent. However, when surgically resected, the majority can achieve a good outcome with additional chemotherapy.

RESUMO

Congenital high airway obstruction syndrome (CHAOS) is a rare condition that can be diagnosed antenatally by ultrasound. It is usually lethal without immediate intervention at delivery. A 24-year-old woman was diagnosed with fetal CHAOS at 27 weeks' gestation. The couple declined termination of pregnancy. A multidisciplinary team including obstetricians, geneticists, paediatric surgeons, neonatologists and anaesthetists was constituted to plan an ex utero intrapartum treatment (EXIT) procedure. After several simulations, a caesarean section was performed at 38 weeks' gestation under deep inhalational anaesthesia. The fetus was fully delivered with placenta remaining in utero to maintain perfusion. A surgical airway was established via tracheostomy in approximately 5 minutes. The operation was then completed with no maternal complications. The child remains well at 3 years of age. To our knowledge, this is the first EXIT procedure performed for CHAOS in the public sector. This procedure can be lifesaving and is possible with proper planning.

RESUMO

Until recently minimally invastive surgery was not performed in neonates. This was because of their small size and distinct physiological characteristics, neonates were not operated on using minimally invasive surgery until recently. Since the introduction of fine laparoscopic instruments, improvements in the surgical techniques and anaesthetic adjustments for laparoscopy, more complex operations are now being performed in neonates. While certain operations such as laparoscopic pyloromyotomy have become routine in many centres, some others require significant infrastructure and experience. Advantages of minimally invasive surgery seen in older children and adults, such as shortened hospital stay and less pain, also apply to neonates. There is no doubt that minimally invasive surgery for neonates is still in its infancy, and for many neonatal conditions requiring surgery, the benefits of minimally invasive surgery need to be established with well-designed studies.

RESUMO

BACKGROUND: Intussusception is a common gastrointestinal emergency in children and appears to have a somewhat different clinical spectrum in developing countries. Its etiology is still unclear, but a link to infective agents and viruses has been highlighted. This study aimed to assess the clinical spectrum and prevalence of intussusception in children from the diverse South African population. METHODS: Retrospective data were obtained from 9 participating pediatric referral units on the occurrence of intussusception in South African children (<14 years old) during a 6-year period (1998-2003). Results were correlated with national population statistics. Intussusception was anatomically classified into ileoileal, ileocolic, and colocolic types. The clinical features, management, outcome, and possible causes were examined. RESULTS: We reviewed the occurrence and clinical spectrum of intussusception in 423 children (age, 0-14 years) presenting with acute intussusception to 9 pediatric surgical centers. The mean duration of symptoms was 1.5 days, but a delayed presentation was common (median delay, 2.3 days). Intussusception occurred throughout the year, with a peak in the summer months. The majority of patients (89%) were <2 years old, and 78% presented at age 3-18 months of age. Crude population estimates indicate an occurrence of 1 case per 3123 population <2 years old. Only 11% of patients presented after 2 years of age, and the age at presentation was significantly lower (P < .05) in black African patients. All ethnic groups were affected. In 84% of patients, intussusception occurred at the ileocolic region junction, in 7% it was ileoileal, and in 9% it was colocolic. Colocolic intussusception appeared more common in black African patients, and associated pathologic conditions (polyps and Burkitt's lymphoma) occurred mainly in older children. Surgical intervention was required in 81% of patients and involved resection of gangrenous bowel in 40%. CONCLUSION: Intussusception appears to be a relatively frequent occurrence in children in South Africa. Although the clinical spectrum appears to vary, there is an apparent link to intestinal infection, which requires further investigation. A collaborative approach is required to ascertain the relationship of intussusception to preventable infections and to improve its diagnosis and management.

RESUMO

The COVID-19 pandemic necessitated rapid changes in healthcare systems and at Red Cross War Memorial Children's Hospital (RCWMCH), Cape Town, South Africa. Paediatric services in particular required adjustment, not only for the paediatric patients but also for their carers and the staff looking after them. Strategies were divided into streams, including the impact of COVID-19 on the hospital and the role of RCWMCH in Western Cape Province, communication strategies, adaptation of clinical services at the hospital, specifically with a paediatric-friendly approach, and staff engagement. Interventions utilised: (i) Specific COVID-19 planning was required at a children's hospital, and lessons were learnt from other international children's hospitals. A similar number of patients and staff were infected by the virus (244 patients and 212 staff members by 21 December 2020). (ii) Measures were put in place to assist creation of capacity at metro hospitals' adult services by accepting children with emergency issues directly to RCWMCH, as well as accepting adolescents up to age 18 years. (iii) The communication strategy was improved to include daily engagement with heads of departments/supervisors by earlymorning structured information meetings. There were also changes in the methods of communication with staff using media such as Zoom, MS Teams and WhatsApp. Hospital-wide information and discussion sessions were held both on social platforms and in the form of smallgroup physical meetings with senior hospital administrators (with appropriate distancing). Labour union representatives were purposefully directly engaged to assess concerns. (iv) Clinical services at the hospital were adapted. These included paediatric-friendly services and physical changes to the hospital environment. (v) Staff engagement was particularly important to assist in allaying staff anxiety, developing a staff screening programme, and provision and training in use of personal protective equipment, as well as focusing on staff wellness. In conclusion, visible management and leadership has allowed for flexibility and adaptability to manage clinical services in various contexts. It is important to utilise staff in different roles during a crisis and to consider the different perspectives of people involved in the services. The key to success, that included very early adoption of the above measures, has been hospital staff taking initiative, searching for answers and identifying and implementing solutions, effective communication, and leadership support. These lessons are useful in dealing with second and further waves of the COVID-19 pandemic.

RESUMO

BACKGROUND: Children constitute 50% of Africa's population. Sub-Saharan Africa has the highest under-five mortality rates in the world. This study is the first to document the availability of paediatric ENT and paediatric surgery services in Africa. OBJECTIVE: To determine the availability of paediatric ENT services in Africa, as well as that of paediatric surgery that would complement paediatric ENT. METHOD: A descriptive observational study in the form of an online questionnaire was distributed by email to known ENT and paediatric surgeons based in Africa. RESULTS: Surgeons from twelve of 23 African countries responded to the survey. Seven countries had both ENT and paediatric surgery responses. In 8 of the 11 countries, the number of ENT surgeons per country was<6% of that of the UK, with 1 ENT surgeon per 414,000 people and 1 paediatric surgeon per 1,181,151 people. Ten of 11 countries reported hearing assessments in schools were poor/unavailable. Seventy-three percent responded positively for access to rigid laryngoscopes, bronchoscopes, cameras and fibre optic cables, tracheostomy, anaesthesia and nurse practitioners. Access was reported as poor/unavailable for balloon dilators 73% (8/11 countries); CPAP machines 73% (8/11) and sleep studies 82% (9/11 countries). Flexible endoscopes were available in 50% (4/8 countries), 75% (6/8 countries) had access to a camera, monitor and stack. Thirty-eight percent (3/9 countries) reported no ENT specialists with paediatric training. CONCLUSIONS: There is a great shortage of paediatric ENT and paediatric surgery services in Africa. More regional training opportunities and health infrastructure for these surgical specialties are needed. Collaborative development of paediatric ENT, surgery and anaesthesia should be considered to improve ENT-related child health in Africa.

RESUMO

BACKGROUND: Telemedicine is increasingly applied in developed settings to facilitate transfer of information to and from burn surgeons across vast geographic areas. WhatsApp is a widely available and extremely user-friendly encrypted smartphone application that does not require the expensive physical and personnel infrastructure that characterizes many of these telemedicine systems. The aim of this study was to review the use of WhatsApp to facilitate paediatric burn injury consultations to a regional burn centre in a developing country, where burn care continues to be thwarted by administrative apathy, poor resource allocation and lack of attention to medical and nursing education at all levels. METHODS: A retrospective review was undertaken of all consultations using WhatsApp over an 18-month period, received by the burn centre's two senior medical practitioners. The specific origin and nature of the telemedicine requests for advice, transfer or follow-up were collected, as were data relating to the demographics of the patients, the aetiology, mechanism and extent of the burn injury. The impact of the system of communication in terms of reductions in admissions and clinic visits was assessed, and a cost analysis was undertaken. Feedback was also obtained from those health practitioners regularly using the service. RESULTS: 838 communications occurred during the study period, which included 1562 distinct clinical queries. 486 interactions (58%) originated from within the hospital, the majority of which were initiated by surgeons in training or burn nurse practitioners. 352 (42%) consultations were from outside the hospital. Queries related to the full spectrum of burn care, including emergency management and stabilization, triage and transfer, the need for escharotomy, fluid resuscitation, wound care, the timing and nature of surgical intervention, as well as follow-up and rehabilitation. While no significant changes in the number of surgical interventions or admissions were observed when compared to the five years prior to the intervention, outpatient visits reduced significantly during the study period. It was estimated that over 150 unnecessary admissions were also avoided as a result of the triage made possible by WhatsApp, which translated into considerable cost saving for the institution. DISCUSSION: Incorporating WhatsApp technology into the daily processes of burn care has significantly improved the quality of paediatric burn care referrals to specialist burn services. Specifically, WhatsApp has contributed to reductions in unnecessary referrals and outpatient visits, facilitated opportunities for continuing medical education, improved the care of major burn injuries through more effective prehospital communication, and enabled greater allocation of scarce specialist resources at the burn centre. This study motivates for the wider application of WhatsApp for burn care referrals, especially in developing countries.

RESUMO

OBJECTIVE: To describe surgical experience with purpura fulminans related to meningococcaemia in a single institution, and to suggest a management protocol. METHODS: A retrospective review was done of patients admitted to the intensive care unit at Red Cross War Memorial Children's Hospital in Cape Town with the clinical diagnosis of purpura fulminans. RESULTS: During a 28-year period (1977-2005) 112 children (average age 3.4 years) were treated for meningococcaemia with purpura fulminans. Overall mortality was 10.7%. Local treatment consisted of measures to improve circulation, infection control and healing of necrotic tissue. Demarcation of necrotic areas was evident at 5.5 days and the average area of skin necrosis was 14% total body surface area (range 2-85%). The lower limbs were predominantly affected. Purpura fulminans resolved in 35 children (31.2%) without skin necrosis. Skin grafting was required in 77 children (68.8%). Factors associated with a poor outcome for peripheral extremity salvage were progressive irreversible skin changes, early disappearance of distal pulses, tense cold swollen extremities and intense pain on passive movement of the affected extremity. Amputations were performed proximal to the area of necrosis, on average 27 days after injury. CONCLUSIONS: Meningococcaemia is a disease with potentially devastating consequences. Early surgical consultation is essential. Skin- and soft-tissue-releasing incisions should be considered early to reduce the incidence of extremity necrosis. Small necrotic areas usually separate spontaneously with secondary healing or can be excised and sutured. Larger necrotic areas should be excised only after demarcation has been established, and can be covered with delayed skin grafting. Amputation should be conservative but may require revision.

RESUMO

BACKGROUND: Trauma is the leading cause of mortality and morbidity worldwide. Blood transfusions play an incremental role in the acute phase, yet practice varies owing to variations in transfusion thresholds and concerns about potential complications, especially in children. OBJECTIVES: To evaluate protocol adherence to blood transfusion thresholds in paediatric trauma patients and determine the degree of blood product wastage, as defined by discarded units. METHODS: A retrospective, descriptive study of trauma patients (age 0 - 13 years) who received a blood transfusion in the trauma unit at Red Cross War Memorial Children's Hospital, Cape Town, South Africa, over a 5.5-year period (1 January 2009 - 1 July 2014). Haemoglobin (Hb) transfusion thresholds were defined as 10 g/dL for neurotrauma patients and patients requiring skin grafting or a musculocutaneous flap (group 1). All other trauma patients had an Hb transfusion threshold of 7 g/dL (group 2). RESULTS: A total of 144 patients were included (mean age 5.2 years (standard deviation (SD) 3.3), 68.1% male). The mean Hb increase after transfusion was 3.5 g/dL (SD 1.7). Adherence to the transfusion Hb threshold protocol was 96.7% for group 1 v. 34.0% for group 2. No complications were reported. Average blood wastage was 3.5 units per year during the study period. CONCLUSIONS: Adherence to paediatric blood transfusion protocol was low in the Hb threshold group <7 g/dL. However, transfusion-related complications and wastage were minimal. Further prospective research is required to determine optimal blood transfusion guidelines for paediatric trauma patients.

RESUMO

BACKGROUND: Percutaneous and open liver biopsies are routine procedures for diagnosing liver pathology. However, the procedure can carry significant morbidity and even mortality, especially in the event of an uncorrectable coagulopathy or a highly vascular tumor. METHODS: A technique described for use in such circumstances involves laparoscopy for identification of the lesion to be biopsied, enables placement of a gelatin hemostatic plug in the core biopsy tract, and confirms hemostasis after percutaneous plugging of the biopsy site. RESULTS: The technique was successfully used for seven patients: six patients with hepatic coagulopathy and one with a highly vascular liver tumor. There were no complications during either the intra- or postoperative period. The patients experienced minimal postoperative discomfort and returned to baseline activity on the first postoperative day. CONCLUSION: The authors believe that the described technique of biopsy site plugging offers a safe alternative for liver biopsy among patients with an uncorrectable coagulopathy and those requiring a biopsy before correction of the bleeding disorder.

RESUMO

Umbilical hernias occur frequently in children but complications are rarely reported. This study assessed the incidence of complicated umbilical hernias in our patients, evaluated data for risk factors and reviewed our management in the light of these findings. We conducted a prospective study of all children needing umbilical hernia repair for complications over a period of 15 years. Patients with para-umbilical and other ventral wall hernias were excluded. In total, 389 children had umbilical hernias repaired during this period (average age 6 years); 28 (7%) of these had complicated hernias. Symptoms included umbilical pain (100%), vomiting (71%) and constipation (28%). The average age of the complicated group was 3 years. All cases had a painful irreducible umbilical mass. Eleven of the 19 children who had an abdominal radiograph showed radiological evidence of small-bowel obstruction and in 5 children there was radiological evidence of pica. Two patients had ischaemic omentum that required resection. Patients who present with localised abdominal pain or an irreducible umbilical mass should be operated on promptly.

RESUMO

Abdominal complications without abdominal injury are infrequently seen in children with major burns. They are divided into those that occur early during the emergency phase of treatment and those that occur late in the course of treatment. One of the most serious late onset complications is non-occlusive mesenteric ischaemia associated with the use of vasoactive drugs. We report on 2 children who late in the course of their burn injury developed ischaemic necrosis of their entire intestine. Both were on propranolol, the administration of which was continued with even during the periods of septic shock which preceded their demise. We are of the opinion that endogenous catecholamine release during hypotensive and septic episodes in conjunction with ß-adrenergic blockage from propranolol could lead to severe splanchnic vasoconstriction from unopposed α-adrenergic activity and hence critical circulation impairment to the bowel in the 2 children.

RESUMO

BACKGROUND: The liver transplant program for infants and children at the Red Cross Children's Memorial Hospital is the only established pediatric service in sub-Saharan Africa. Since 1985, 250 infants and children have been assessed and 155 accepted for transplantation. METHODS: Since 1987, 76 children (range 6 months to 14 years) have had 79 liver transplants, with biliary atresia being the most frequent diagnosis. The indications for transplantation include biliary atresia (n = 44), metabolic (n = 7), fulminant hepatic failure (n = 10), redo transplants (n = 3), and other (n = 15). Three combined liver/kidney transplants have been performed. Forty-nine were reduced-size transplants with donor: recipient weight ratios ranging from 2:1 to 11:1, and 29 children weighed < 10 kg. RESULTS: Fifty-six (74%) patients survived 3 months to 12 years posttransplant. Cumulative 1- and 5-year patient survival data are 79% and 70%, respectively. However, with the introduction of prophylactic intravenous gancyclovir and the exclusion of hepatitis B virus (HBV) IgG core Ab-positive donors, the projected 5-year pediatric survival has been >80%. Early (<1 month) post-liver-transplant mortality was low, but included: primary malfunction (n = 1); inferior vena cava thrombosis (n = 1); bleeding esophageal ulcer (n = 1); and sepsis (n = 1). Late morbidity and mortality was mainly due to infections: de novo hepatitis B (5 patients, 2 deaths); Epstein-Barr virus (EBV)-related posttransplantation lymphoproliferative disease (12 patients, 7 deaths); and cytomegalovirus disease (10 patients, 5 deaths). Tuberculosis (TB) treatment in three patients was complicated by chronic rejection (n = 1) and TB drug-induced subfulminant liver failure (n = 1). CONCLUSIONS: Despite limited resources, a successful pediatric program has been established with good patient and graft survival figures and excellent quality of life. Shortage of donors due to HBV and human immunodeficiency virus (HIV) leads to significant waiting list mortality and infrequent transplantation.

RESUMO

Drugs used for immunosuppression have been implicated in causing numerous long-term side effects including nephrotoxicity, glucose intolerance, and hyperlipidemia. In this study, we reviewed our pediatric liver transplant recipients in terms of glomerular filtration rate (GFR) as well as fasting glucose and lipid profiles. To date, 79 pediatric liver transplantations have been performed at our center: 24 transplantations of at least 5 months to a maximum of 7.3 years posttransplant are reviewed herein. The mean time posttransplantation was 2.1 years. Nine boys and 15 girls showed a distribution of 19 mixed race, 3 black, and 2 white patients. The mean age at the time of transplantation was 6.6 years (0.8-13.3 years) with 8 cases under the age of 3 years. All recipients started with Cyclosporine Neoral (CSA) as first line, but, at the time of testing, immunosuppression included 5 children on CSA and 19 on Tacrolimus. Radionuclide 51 Cr-EDTA Glomerular Filtration Rates (GFR) showed a range from 21 to 220 mL/min/1.73 m2 (mean 96.1, median 89.8). Seven cases had a GFR less than 75 mL/min/1.73 m2. Twenty-one children were on antihypertensives agents: 15 children on 1 agent and 6 children on 2 agents. On full fasting lipid profiles, the total cholesterol ranged from 2 to 7.9 mmol/L (mean 4.4). Only 1 child is currently on statin therapy. Fasting glucose ranged from 3.2 to 5.9 mmol/L (mean 4.1) No difference was observed in glucose values between CsA and Tacrolimus. Thus, immunosuppressive therapies, such as the calcineurin inhibitors, are known to cause nephrotoxicity, which is of concern in pediatric liver transplant recipients. Almost all our patients currently require antihypertensive therapy. At present, the renal function is adequate in the majority of the group, but this study needs to be extended to other pediatric liver transplant recipients with particular emphasis on those who are more than 5 years posttransplantation.
