Bolus versus continuous feeding regimens post gastrostomy tube placement in children

Background/purposeOwing to the frequency of gastrostomy tube placement in children and the numerous regimens used to start feeds after placement we attempted to see if it matters if the initial feeds after a gastrostomy tube placement are provided in a bolus or continuous manner.MethodsUsing a prospective randomized trial, children were randomized to initial bolus or continuous chimney feeding after gastrostomy tube placement. Feeding tolerance and complications related to the gastrostomy tube were collected for 4 weeks after placement.ResultsDemographics were similar in the two groups. Times to goal feeds were similar in both groups, but in the first two weeks more feeding modifications were required in the bolus group. Other than the rate of leakage during the second week after placement which occurred more in the bolus group, all other clinical outcomes were similar in the two groups.ConclusionsOther than minor, clinically insignificant differences noted above, the method of initial feeding after a gastrostomy tube placement does not affect feeding tolerance or gastrostomy tube complication in the first month after placement.Level of evidenceTherapeutic, level II.     

Technology assessment in health care--decision makers and health care providers: what they need to know

The assessment of a new technology requires decision makers to gather information in many different fields. The questions addressed are technical, medical, ethical, legal and economic in nature. Learning from the experience of our own country and of others, we present here the sum of the information we deem necessary to decide on whether to adopt a new technology or not, and which strategy to choose for its implementation.     

Factors predicting the long-term success of maintenance cyclosporine monotherapy after kidney transplantation

BACKGROUND: The theoretical aim of maintenance cyclosporine monotherapy (mCsA) after kidney transplantation is to reduce the incidence of the metabolic complications of corticosteroids and to minimize the adverse effects of excessive long-term immunosuppression. This study was performed in low-immunological-risk cadaveric kidney transplant recipients to evaluate the risks and benefits of mCsA and the long-term graft survival, and to determine the factors predicting success of this policy. METHODS: The multicenter retrospective study was conducted in 329 Caucasian patients receiving mCsA out of 728 first cadaveric kidney transplant recipients. The inclusion criteria were: HLA antibodies < or =25%, serum creatinine <200 micromol/L, and no rejection or only one rejection episode. At the end of the study, we compared the group of patients successfully treated with mCsA (successful group) with those requiring additional immunosuppressive agents (unsuccessful mCsA group). RESULTS: Overall patient and graft survival rates for the 728 first cadaveric graft were 92% and 64%, respectively, at 8 years. Out of 329 patients enrolled in mCsA, 240 were maintained on this treatment and 89 were withdrawn (3 deaths, 18 graft losses, 68 functional grafts). The 8-year graft survival in the 329 enrolled mCsA patients was 84%, 95% in the successful mCsA group, and 70% in the unsuccessful mCsA group. Multivariate analysis showed that the factors predicting success of mCsA were: donor age <40 years (P = 0.001), serum creatinine at mCsA initiation <125 micromol/L (P = 0.02), no rejection episode before mCsA initiation (P = 0.005), and glomerulopathy as the primary renal disease (P = 0.001). CONCLUSION: Numerous kidney transplant recipients with a low immunological risk and good and stable renal function may benefit from discontinuation of prednisone and azathioprine in order to reduce the complications related to these drugs. This therapeutic approach had no adverse impact on the overall long-term graft survival for "low risk" and successful patients.     

Comparing sulindac with indomethacin for closure of ductus arteriosus in preterm infants

Objectives: A prospective study comparing the efficiacy and side-effects of oral sulindac with intravenous indomethacin in clinically stable preterm infants (<1750 g) requiring non-invasive closure of haemodynamically significant patent ductus arteriosus.
Methodology: As maturity and birthweight are the two major determinants of ductal closure, infants were matched as closely as possible for these parameters. An eligible patient was first assigned to the sulindac group and a subsequent patient with similar gestational age (± 1 week) and birthweight (±100 g) to the previously recruited infant would automatically receive indomethacin. A total of eight infants were enrolled in each group.
Results: The ductus arteriosus was successfully closed in all eight infants receiving indomethacin, and in seven of eight infants receiving sulindac. No significant differences were found with regards to the ductal size between the two groups at diagnosis or on each of the consecutive days of treatment ( P >0.25). More renal adverse effects were encountered in the indomethacin group. Significant differences in changes from baseline value for urine output, plasma sodium, urea and creatinine concentrations were noted at 24, 48 and 72 h after commencement of treatment between the two groups ( P <0.05). All the parameters returned to normal or pre-treatment levels 48 h after stopping therapy. Unexpectedly, severe gastrointestinal complications were encountered in the sulindac group.
Conclusions: Sulindac is capable of promoting ductal constriction in clinically stable preterm infants without compromising the renal function. The spectrum of gastrointestinal complications observed in sulindac treated infants were similar to those described for indomethacin. The use of sulindac for ductal closure in the preterm infant should remain experimental.     

Fatal meningoencephalitis due to Bacillus anthracis

Abstract: We report the first case of fatal anthrax meningoencephalitis in Hong Kong over the past 60 years. A 13 year-old boy presented with right lower quadrant pain, diarrhoea and progressive headache. Lumbar puncture yielded gram positive bacilli initially thought to be Bacillus cereus, a contaminant. He was treated with ampicillin and cefotaxime, but died 3 days after hospitalization. The organism isolated from blood and cerebrospinal fluid was later identified as Bacillus anthracis.     

Effect of a structured asthma education program on hospitalized asthmatic children: A randomized controlled study

BACKGROUND: The aim of this study was to compare the effectiveness of an intensive asthma education program (group B) with that of a standard asthma education program (group A). METHODS: A prospective randomized single blinded study was conducted in the pediatric department of a public hospital in Hong Kong. Children aged 2-15 years admitted to the pediatric department with an acute attack of asthma were recruited. A standard asthma education program (group A) or an intensive asthma education program (group B) for children were offered. The main outcome measures include the number of visits to the emergency department and the number of hospitalization for asthma during the 3 month follow-up period. RESULTS: A total of 45 children were in group A and 55 in group B. Group B had statistically significant reductions in the number of visits to the emergency department and the number of hospitalizations. Drug compliance was also significantly improved in group B. Parents' satisfaction rate was also higher in group B. CONCLUSION: The intensive asthma education program might be more cost effective than the standard asthma education program in the management of asthmatic children admitted to hospital in Hong Kong.     

Nutritional intervention during maxillomandibular fixation of jaw fractures prevents weight loss and improves quality of life

Maxillomandibular fixation (MMF) for the management of jaw fractures leads to compromised nutritional intake and consequent weight loss and poor quality of life (QoL). The present study aimed to evaluate the effectiveness of a home-based dietary plan to prevent weight loss, and its effect on the QoL of patients who underwent four weeks of MMF for the treatment of maxillofacial fractures. A total of 50 patients were randomised into nutritional intervention (Group1) and non-intervention groups (Group 2). Patients in Group1 were counselled by a dietitian and given a diet plan. Patients in Group 2 were advised to take a liquid diet of their own choice in the form of shakes, juices, and milk, along with protein supplements. Patients in Group1 lost significantly less weight than those in Group 2 (p=0.001) at week four of follow up. Group1 patients had significantly better oral health-related QoL in the ‘physical pain’ domain during the two weeks of MMF, and in the ‘physical discomfort’ and ‘psychological disability’ domains two weeks after the release of MMF. They had significantly better nutrition-related QoL in all the domains during the two weeks of MMF and, except for the ‘physical’ domain, also during the two weeks after its release. Individual home-based diet plans effectively helped the patients maintain their weight and improved QoL.
