ReviewTransient neurologic symptoms (TNS) following spinal anaesthesia with lidocaine versus other local anaesthetics.
Spinal anaesthesia has been in use since the turn of the late 19th century. The most serious complication of this technique is damage to the spinal cord or nerve roots resulting in lasting neurologic sequelae. Such serious adverse effects seldom happen. There has been an increase in the number of reports during the last nine years implicating lidocaine as a possible cause of temporary and permanent neurologic complications after spinal anaesthesia. Follow-up of patients who received uncomplicated spinal anaesthesia revealed that some of them developed pain in the lower extremities after an initial full recovery. This painful condition that occurs in the immediate post-operative period was named "transient neurologic symptoms" (TNS). ⋯ The risk of developing TNS after spinal anaesthesia with lidocaine was significantly higher than when bupivacaine, prilocaine and procaine were used. The term "TNS", which implies a positive neurologic finding, should not be used for this painful condition, which is in fact comparable to another common adverse effect after spinal anaesthesia - lower back pain. How much the pain in the lower extremities influences patient satisfaction is not elucidated clearly in the literature.

Staphylococcus aureus causes pulmonary infection in young children with cystic fibrosis (CF). Prophylactic antibiotics are widely prescribed in the hope of preventing infection with Staphylococcus aureus and lung damage. Antibiotics also have adverse effects and long-term use might lead to chronic infection with organisms like Pseudomonas aeruginosa. ⋯ Anti-staphylococcal antibiotic prophylaxis leads to fewer children having isolates of Staphylococcus aureus, when commenced early in infancy and continued up to six years of age. The clinical importance of this finding is uncertain. Further research may establish whether the trend towards more children with CF with Pseudomonas aeruginosa, after four to six years of prophylaxis, is a chance finding. Future work should explore whether choice of prophylactic antibiotic or duration of treatment might influence infection with Pseudomonas aeruginosa.

Review Meta AnalysisCorticosteroid therapy for nephrotic syndrome in children.
In nephrotic syndrome protein leaks from the blood to the urine through the glomeruli resulting in hypoproteinaemia and generalised oedema. Children with untreated nephrotic syndrome frequently die from infections. The majority of children with nephrotic syndrome respond to corticosteroids. However about 70% of children experience a relapsing course with recurrent episodes of oedema and proteinuria. Corticosteroid usage has reduced the mortality rate in childhood nephrotic syndrome to around 3%, with infection remaining the most important cause of death. However corticosteroids have known adverse effects such as obesity, poor growth, hypertension, diabetes mellitus, osteoporosis and adrenal suppression. The original treatment schedules for childhood nephrotic syndrome were developed in an ad hoc manner. The optimal doses and durations of corticosteroid therapy that are most beneficial and least harmful have not been clarified. ⋯ Children in their first episode of SSNS should be treated for at least three months with an increase in benefit being demonstrated for up to seven months of treatment. In a population with a baseline risk for relapse following the first episode of 60% with two months of prednisone, daily prednisone for four weeks followed by alternate day therapy for six months would be expected to reduce the number of children experiencing a relapse by about 33%. In children who relapse frequently, deflazacort deserves further study.

Review Meta AnalysisIndomethacin for asymptomatic patent ductus arteriosus in preterm infants.
Patent Ductus Arteriosus (PDA remains a significant cause of mortality and morbidity in premature infants. Indomethacin is an effective treatment to close a PDA, and has been used for many years with several treatment regimes, including prophylactic use in all at risk premature infants. There are however concerns regarding adverse side effects of indomethacin. By targeting a group of infants with an asymptomatic PDA, rather than treating all VLBW infants prophylactically, indomethacin use would be restricted, limiting the possibility of significant side effects to those with greater chance of benefit. ⋯ This review demonstrates a significant decrease in the incidence of symptomatic PDA following treatment of an asymptomatic PDA with indomethacin. There is also a small but statistically significant decrease in the duration of requirement for supplemental oxygen. There are no reported long term outcomes in the included trials, and so it is not possible to comment on possible long term effects. Further studies are required to determine the long term benefits or harms of closing a PDA prior to the onset of symptoms.

Review Meta AnalysisTherapy-based rehabilitation services for stroke patients at home.
Stroke Unit care is now accepted as an effective service model for hospital care, but the effectiveness of outpatient care is less certain. This review focuses on therapy-based rehabilitation services targeted at stroke patients living at home. ⋯ Therapy-based rehabilitation services targeted towards stroke patients living at home appear to improve independence in personal activities of daily living. However, the evidence is derived from a review of heterogeneous interventions and therefore further exploration of the interventions is justifiable.
