Long-term outcome of anorectal malformations: the patient perspective.

To assess the long-term outcome of surgery for anorectal malformations (ARM) from the patient's perspective. One hundred and sixty seven children were operated for ARM between 1982 and 2000. Disease impact questionnaires to assess both clinical and psychological outcomes were sent to 137 eligible families. Statistical analysis was performed using SPSS version 11.5. The response rate was 61% (n=84). Sixty six percent had soiling. There was no significant difference in the incidence of soiling between genders or between the younger child and adolescent. Soiling was significantly increased in high (86%) and intermediate (79%) compared to low (43%) malformation (P=0.001). Constipation was seen in 62% and abdominal pain in 49%, with no significant difference between malformation levels. Overall, 71% had associated anomalies. Although 44% had a documented urological abnormality, clinical significant problems were seen in only 30%. Eighty percent of the children had one or more behavioural problems and 15% expressed suicidal thoughts. ARM had a negative impact on the social life of the child in 52% and on family functioning in 50%. Soiling (P=0.000), presence of associated anomalies (P=0.001), constipation (P=0.005), level of ARM (P=0.015) and abdominal pain (P=0.039) correlated significantly with psychosocial morbidity. Despite these findings, 62% of adolescents and 71% of children below 12 years with their parents reported above average global hopefulness score, remaining hopeful for the future. Children with ARM have ongoing physical and social morbidity, indicating the need for continuing multidisciplinary review and support to optimise their quality of life.

Laser Doppler imaging of paediatric burns: burn wound outcome can be predicted independent of clinical examination.

This study sought to assess the validity of independent, blinded reporting of Laser Doppler Imaging (LDI) prediction of burn wound outcome in children. Two experienced paediatric burn consultants were invited to report on LDI scans performed routinely within 3 days of burn. They were provided with the LDI flux image, a low-resolution colour digital photograph of the burnt area and a basic history. Report predictions were correlated with outcome. Reports were compiled on 50 scans performed on 31 patients at a mean of 54h post burn. Of the 100 reports generated, mean correlation with outcome was 97%. If the LDI predicted a deep burn, it was always correct. Non-correlations were due to a number of factors including inadequate scanning of the affected area, excessive movement and residual wound debris. Accurate prediction of burn wound outcome could be made via the standard information generated by LDI and appeared more reliable than clinical prediction. The correlation improved with increasing experience with LDI.

Language barriers and paediatric burns: does education make a difference?

A focused first aid education campaign was conducted in Sydney in 1996 for parents of children from Non-English speaking backgrounds (NESB) to improve their knowledge of correct burns first aid treatment (BFAT). This study sought to determine the correlation, if any, between the reported beneficial results of this education campaign and the subsequent severity of burns in children. A retrospective review of all patients admitted to the state Burns Unit at The Children's Hospital at Westmead (CHW) over a 7-year period from January 1995 to December 2001 was performed. Number of patients, language spoken at home (English, Chinese, Arabic, Vietnamese or Other) and the rate of burns requiring skin grafting was assessed. A total of 1,283 patients were admitted over 7 years. Skin grafting was required in 544 (42%). NESB children required grafting in up to 88% of cases prior to the first aid education campaign, reducing to a minimum of 37% at 1 year and 65% at 5 years following the campaign. This compared to 40 and 36%, respectively, for English speaking children. While the initial decrease in grafting requirements may reflect an effective education campaign, the subsequent rise suggests the need for reinforcement.

Double bubble, double trouble.

Duodenal atresia (DA) is not uncommon, either as an isolated anomaly or associated with trisomy 21, malrotation, or cardiac anomalies. It may be diagnosed on antenatal ultrasound by a "double-bubble" sign, which typically persists after birth on a plain abdominal radiograph. DA as a familial association is rare but has been reported with or without other associated anomalies. We report DA in two siblings of nonconsanguineous parents, one case occurring with an annular pancreas in association with gestational diabetes. These two cases suggest possible genetic and environmental components in the aetiology of this anomaly.

Blunt traumatic diaphragmatic injuries in children.

Diaphragmatic injuries following blunt trauma are rare. From January 1988 to February 2002 eight children were treated at the Children's Hospital at Westmead for diaphragmatic injury. Male to female ration was 5:3. Motor vehicle crashes were the most common cause. The injury was left-sided in four, right sided in three and central in one. Initial plain radiograph and computerised tomography detected the injury in 50% of cases. Laparotomy, contrast study and autopsy identified the rupture in one each. Associated injuries were present in all cases. Seven children had laparotomy and repair of the diaphragmatic rupture. The commonest site of rupture was posterolateral (37.5%). Diagnosis was delayed in two cases. There were two deaths (25% mortality) in the series, both due to associated injuries. Although rare, diaphragmatic rupture must be considered in any child with thoracoabdominal injury. Diagnosis may be difficult and require extensive investigation. Mortality usually results from associated injuries.

Diagnostic accuracy of surgeon-performed focused abdominal sonography (FAST) in blunt paediatric trauma.

AIM: To study the diagnostic accuracy and clinical efficacy of surgeon-performed focused abdominal sonography (FAST) in paediatric blunt abdominal trauma (BAT). MATERIALS AND METHOD: This was a prospective, single blinded study conducted at The Children's Hospital at Westmead Sydney (CHW). All patients with BAT that justified a trauma call activated on presentation to the Emergency Department (ED) had a FAST performed by the Trauma Fellow. The attending surgical team was blinded to the result of the FAST. An independent radiologist reviewed the FAST pictures, and the findings were compared with computerised tomography (CT), ultrasound (US), laparotomy and the clinical outcome of the patient. Sensitivity, specificity and predictive values were calculated. RESULTS: A total of 85 patients (39 M; 26 F) were enrolled in the study between February 2002 and January 2003. The age ranged between 4 months and 16 years. The mean Injury Severity Score (ISS) was 6 (range 1-38). FAST was performed in a mean time of 3 min. Inter-rater agreement was 96%. FAST was positive in nine as confirmed by a CT scan of the abdomen. Three patients underwent laparotomy, two for bowel injuries and one for a Grade III liver laceration. Of the remaining 76, 19 had a CT, which showed evidence of intra-abdominal injury in seven patients. There were two false negative studies resulting in a sensitivity of 81%, specificity of 100%, negative predictive value of 97%, positive predictive value of 100% and an accuracy of 97%. CONCLUSIONS: Surgeon-performed FAST for BAT was safe and accurate with a high specificity. It would seem a potentially valuable tool in the evaluation of paediatric blunt trauma victims for free fluid within the peritoneal cavity.

Perforating small bowel injuries in children: influence of time to operation on outcome.

The purpose of this study was to determine whether delay in the diagnosis of small bowel injury (SBI) affected the outcome of paediatric patients who required surgical interventions in the treatment of small bowel injuries. A retrospective chart review was performed on children with traumatic SBI requiring surgical management between January 2000 and December 2002. Diagnostic interval was defined as the time from presentation to operative treatment and delay was an interval of greater than 8 h. Thirteen patients were admitted for operative treatment of SBI. Nine cases were the result of motor vehicle trauma. The mean diagnostic interval for all patients was 9.1 h+/-7.4 h (range 0.6 h-22.5 h). Six patients had a diagnostic delay with a mean diagnostic interval of 15.5 h+/-5.5 h. There was no statistically significant difference found between the prompt and delayed diagnosis groups in terms of complications or length of hospital stay. Our finding of no difference between the prompt and delayed diagnosis groups and a diagnostic delay no longer than 22.5 h may suggest that our local methods of diagnosis and treatment assist in the prevention of unnecessary complications and death.

Sports-related pneumothorax in children.

Pneumothorax after blunt chest trauma in the absence of rib fractures is uncommon and has only rarely been reported as a result of sporting activity. Presentation may vary from an apparently normal physical examination in the presence of a small pneumothorax to hemodynamic compromise in the presence of a tension pneumothorax. High fitness levels in athletes may result in failure to recognize symptoms and delay diagnosis, potentially increasing morbidity. It is imperative for the emergency physician to exclude pneumothorax in children who present with chest pain after blunt chest trauma from sports injury. We report our experience with and the management of 3 patients with pneumothoraces.

Paediatric trauma.

Trauma remains the most common cause of death in childhood after the first year of life. It accounts for considerable morbidity that may extend into adult life at great cost to the community. Despite the scale of the disease, paediatric trauma and injury prevention research attract little funding. International data indicate that children in Australia and New Zealand would benefit from improved injury prevention strategies and the introduction of a more formalized paediatric trauma system. Such a system would need to take account of Australasian geographical and population distribution characteristics, which mandate local provision of expert and immediate care in rural areas. There would appear to be economic and clinical arguments for the introduction of an ambulance trauma bypass system for stable but severely injured children in metropolitan areas with a paediatric trauma centre.

Biliary dyskinesia: is the problem with Oddi?

We report our experience of cholecystectomy for treating symptoms suggestive of biliary disease in association with a decreased gallbladder ejection fraction (GBEF) but without evidence of cholelithiasis. Five children with normal biliary ultrasounds were evaluated between January 1990 and December 2000 for recurrent upper abdominal pain. Based on a cholecystokinin (CCK)-provoked GBEF of less than 50% and the absence of any other gastrointestinal pathology, patients underwent cholecystectomy with operative cholangiography for presumed biliary dyskinesia. Pathological examination demonstrated chronic inflammation in all cases. Two patients had complete resolution of their symptoms, but three had persistent pain following surgery. Biliary dyskinesia seems an uncommon cause of persistent abdominal pain in childhood. Cholecystectomy was not always effective in relieving symptoms. Biliary scintigraphy with CCK provocation should not be used as the sole criterion for cholecystectomy. Sphincteric manometry may be valuable in the assessment of this small group of patients to avoid inappropriate intervention. The future perhaps lies in better understanding of the physiological action and pharmacological control of the sphincter of Oddi.

Pancreatic trauma in children.

BACKGROUND/PURPOSE: The aim of this study was to determine the etiology, associated injuries, and outcome of children with pancreatic injuries. METHODS: A retrospective review was conducted of children under 16 years with pancreatic trauma admitted to the Children's Hospital at Westmead (CHW) from January 1983 to September 2002. Deaths were reported to the New South Wales Paediatric Trauma Death Registry (State Registry) from January 1988 to September 2002. RESULTS: Sixty-five cases were identified: 46 patients were admitted to CHW, and 22 deaths were reported to the State Registry (including 3 deaths at CHW). The median age was 6 years (range, 1 to 14 years). Boys accounted for 60% (n = 40) of cases, decreasing to 50% (n = 11) of those that died. Motor vehicle injuries (MVI) were the most common mechanism, accounting for 40% of survivors and 77% of those who died. Children were restrained incorrectly in 48% of all cases and in 67% of those who died. Significantly more children who died had head, chest, and abdominal visceral injuries, compared with those who survived. Death occurred as a result of head injuries in 68%, with only 3 deaths directly attributed to pancreatico-duodenal injuries. CONCLUSIONS: Pancreatic injuries remain uncommon in children. The most frequent mechanism was MVI, with incorrect use of passenger restraints an important contributing factor. Whereas mortality was mainly caused by other injuries, 3 deaths were directly attributable to pancreato-duodenal trauma.

Small bowel perforation in the premature neonate: congenital or acquired?

To determine the potential aetiological factors of small bowel perforation in the premature neonate, we performed a retrospective chart review of those neonates with spontaneous intestinal perforation (SIP) of the small bowel seen in our tertiary paediatric hospital between January 1980 and December 2000. Data were collected on gestational feto-maternal health, medical interventions prior to perforation and the subsequent operative and laboratory findings. There were 23 patients with SIP of the small bowel over the 21-year review; 65% were male. There were 7 twin pregnancies but no cases linked to maternal drug abuse. The median gestational age was 27 weeks, the median birth weight 973 g, 19 neonates required ventilation, 15 steroids and 13 indomethacin. The median age at diagnosis was 7 days, heralded by rapid development of abdominal distension in 22 patients. Surgical intervention in addition to insertion of a peritoneal drain was required in 19 patients. Positive microbiological cultures of blood or peritoneal fluid at operation were documented in 8 patients; 5 grew Staphylococcus epidermidis and 4 Candida species. Perforations were located in the ileum in 20 and the jejunum in 1. Deficiency of the muscularis propria was found in 6 patients. Of the 6 deaths, 2 neonates had significant co-morbidity in addition to extreme prematurity. Small bowel SIP occurs in the premature neonate after the first week of life and usually presents with abdominal distension. Putative risk factors identified included twin gestation, neonatal ventilation, use of steroids and indomethacin, infection with Staphylococcus epidermidis and Candida species and deficiency of enteric smooth muscle.

Tracheomalacia, timing of symptoms, and thymic enlargement: cause or coincidence?

The authors report a case of severe primary tracheomalacia in a 3-month-old boy. The left lobe of the enlarged thymus was resected at operation to facilitate aortopexy. The authors suggest a possible role for the enlarging thymus contributing to the delayed onset of the symptoms of tracheomalacia, despite the presence of the tracheal lesion from birth.

Isolated and multisystem hepatic trauma in children: the true role of non-operative management.

We retrospectively reviewed children with hepatic injuries (HI) admitted to our institutions from January 1982 to December 1999. Specific comparison was made of isolated (IHT) and multisystem hepatic trauma (MHT). Over the 18-year period 127 patients were identified with HI, 91 (71%) with MHT and 36 with IHT. The median age was 8 years (range 13 months to 14 years). Motor vehicle injury was the most common mechanism in both groups, but bicycle injuries were more common in IHT ( P<0.001). Shock ( P=0.02), the requirement for blood transfusion ( P<0.001), and operative intervention for the HI ( P=0.001) were all significantly more common in MHT. The distribution of liver injury grades was similar between the two groups. Twenty-two (17.3%) children died and in 18 the HI was the main cause or contributed significantly. There were 19 and 3 deaths in the MHT and IHT groups, respectively, a difference that was not significant. After excluding children with minor HI, 27 (39%) required operative intervention within 24 h of their injury. This suggests that the high success rate for non-operative management of HIs in the literature may have been biased by the inclusion of a significant proportion of subclinical injuries.

Laser Doppler imaging prediction of burn wound outcome in children.

The ability of laser Doppler imaging (LDI) to evaluate burn depth in children was investigated. Fifty-seven patients were prospectively studied over a 10-month period. Each patient was clinically assessed, photographed and independently scanned between 36 and 72 h of the burn. Patients were reviewed until wound healing had occurred within 12 days or skin grafting had been performed. The median age was 1 year and 10 months (range 5 months to 15 years and 8 months). The median body surface area burnt was 7.0% (range 0.5-30%). In 30 patients, the burn did not heal within 12 days, 17 of which were grafted. Clinical examination correctly determined 66% of deep partial or full thickness burns between 36 and 72 h of injury compared to 90% using LDI. The LDI was also more specific; correctly diagnosing 96% of superficial partial thickness burns as opposed to 71% on clinical examination. Moderate degrees of movement did not appear to limit the accuracy of the scan.

Penetrating injuries in children: is there a message?

OBJECTIVES: To determine the frequency, management and outcome of penetrating trauma in children. METHODS: A retrospective review of penetrating injuries in children under 16 years of age admitted to the Children's Hospital at Westmead (CHW), and deaths reported to the New South Wales Paediatric Trauma Death (NPTD) Registry, from January 1988 to December 2000. Patient details, circumstances of trauma, injuries identified, management and outcome were recorded. RESULTS: Thirty-four children were admitted to the CHW with penetrating injuries during the 13-year period. This represented 0.2% of all trauma admissions, but 3% of those children with major trauma. The injury typically involved a male, school-age child that fell onto a sharp object or was assaulted with a knife or firearm by a parent or person known to them. Twenty-five children (75%) required operative intervention for their injuries and 14 survivors (42%) suffered long-term morbidity. Thirty children were reported to the NPTD Registry over the same interval, accounting for 2.3% of all trauma deaths in New South Wales. Of these, a significant minority was injured by falls from a mower or a tractor towing a machine with blades. CONCLUSIONS: Penetrating injuries are uncommon, but cause serious injury in children. There are two clear groups: (i) those dead at the scene or moribund on arrival, in whom prevention must be the main aim; and (ii) those with stable vital signs. Penetrating wounds should be explored in the operating theatre to exclude major injury. Young children should not ride on mowers or tractors.

Congenital lobar emphysema: Like father, like son.

Congenital lobar emphysema (CLE) is an uncommon cause of progressive respiratory distress that typically presents in the first few days of life. There has been a previous report of CLE in a mother and daughter. The authors describe 2 cases involving the right upper and middle lobes in a father and son secondary to relative deficiency of the bronchial cartilage. This provides additional evidence for inherited factors in the etiology of CLE.
