With advancing paediatric healthcare, the use of central venous lines has become a fundamental part of management of neonates and children. Uses include haemodynamic monitoring and the delivery of lifesaving treatments such as intravenous fluids, blood products, antibiotics, chemotherapy, haemodialysis and total parenteral nutrition (TPN). Despite preventative measures, central venous catheter-related infections are common, with rates of 0.5-2.8/1000 catheter days in children and 0.6-2.5/1000 catheter days in neonates. Central line infections in children are associated with increased mortality, increased length of hospital and intensive care unit stay, treatment interruptions, and increased complications. Prevention is paramount, using a variety of measures including tunnelling of long-term devices, chlorhexidine antisepsis, maximum sterile barriers, aseptic non-touch technique, minimal line accessing, and evidence-based care bundles. Diagnosis of central line infections in children is challenging. Available samples are often limited to a single central line blood culture, as clinicians are reluctant to perform painful venepuncture on children with a central, pain-free, access device. With the advancing evidence basis for antibiotic lock therapy for treatment, paediatricians are pushing the boundaries of line retention if safe to do so, due to among other reasons, often limited venous access sites. This review evaluates the available paediatric studies on management of central venous line infections and refers to consensus guidelines such as those of the Infectious Diseases Society of America (IDSA).

BACKGROUND: Children remain under-represented in national antiretroviral treatment (ART) programmes in settings with limited resources and high HIV prevalence. In Malawi, an increasing number of HIV-infected children have been started on ART with split tablets of an adult fixed-dose combination drug in the past few years. In 2006, the national paediatric ART regime was changed from Triomune 40 (T40) to Triomune 30 (T30). METHODS: This was a cross-sectional study conducted at the paediatric ART clinic in Blantyre (Malawi) from September 2006 to July 2007. Children taking T30 for > 6 weeks from each dosing weight band (

In many settings, HIV infected children are looked after with limited access to CD4 cell count or viral load. The decision to initiate antiretroviral therapy (ART) is made clinically, based on the WHO paediatric staging criteria, which were revised in 2006. Results of using new and old criteria were compared. of 694 children, 626 (90.2%) fulfilled criteria to start ART when applying the new WHO staging guidelines, whereas 330 (47.6%) children were eligible for ART when using the old WHO criteria. This signifies a marked rise in the number of paediatric patients qualifying for ART on clinical grounds.

AIM: to review the presentation and management of child sexual abuse cases presenting to Queen Elizabeth Central Hospital (QECH), Blantyre, since the introduction of an HIV postexposure prophylaxis programme. METHODS: Demographic and medical data was collected from all children presenting to Queen Elizabeth Central Hospital, Blantyre, Malawi between January 2005 and February 2007 with alleged child sexual abuse (CSA). RESULTS: Between January 2005 and February 2007, 217 children presented with alleged CSA. This an average of 3 more per month since the previous year, a 57 percent increase. Physical examination showed signs of trauma 60% (130/217) of cases. 63% (137/217) of the cases presented within 72 hours of defilement. Overall in 42% (92/217) of children a one month course of HIV PEP was indicated and given. In 58% (125/217) HIV PEP was not indicated in view of normal examination, presentation too late (>72 hrs after abuse), multiple abuse episodes in the last 6 months, HIV test positive or HIV test refused. In 66% (144/217) of assessed children antibiotic treatment was given for the prevention and/ or treatment of sexually transmitted infections (STIs). CONCLUSIONS: the introduction of an HIV PEP programme for victims of CSA has lead to increased numbers presenting and being treated. In conclusion it is likely that a significant number of children have been prevented from acquiring HIV and other STIs following CSA. The key area where our service needs to be improved is in establishing documented follow up of all cases to monitor medication compliance, side effects and rates of HIV seroconversion following CSA.

AIM: Matrix metalloproteinases (MMPs) -9 and -2 degrade type-IV collagen, a major constituent of lung basement membrane, and may have a role in the pathogenesis of neonatal chronic lung disease (CLD). We determined factors influencing MMP levels in neonatal bronchoalveolar lavage (BAL) fluid to establish whether an imbalance between MMP and its inhibitor could be implicated in CLD. METHODS: We measured MMP-9 and -2 and tissue inhibitor of metalloproteinase-1 (TIMP-1) levels in 316 BAL fluid samples from 121 babies of gestational ages 23 to 42 wk over the first 14 d of life to determine effects of gestation and postnatal age. Median MMP-9, -2, TIMP-1 and MMP-9/TIMP-1 ratio in BAL were further studied in a subgroup of 85 babies

OBJECTIVE: Matrix metalloproteinase-9 (MMP-9) degrades type IV collagen, the major constituent of lung basement membrane. We studied the effects of chorioamnionitis and antenatal corticosteroids on bronchoalveolar lavage (BAL) fluid levels of MMP-9, and its inhibitor, TIMP-1 in preterm infants. STUDY DESIGN: a prospective study was performed on serial BAL samples from 79 ventilated preterm infants at less than 33 weeks' gestation, 18 of whom were from pregnancies complicated by chorioamnionitis. MMP-9 levels were measured by gelatin zymography and TIMP-1 by enzyme-linked immunosorbent assay, and the median value for each infant was calculated. The presence and severity of chorioamnionitis were defined histologically. RESULTS: BAL fluid MMP-9 levels were higher in preterm infants in the chorioamnionitis group (86 [29-518] vs 13 [3-43] ng/mL, P =.001), and levels increased stepwise with the increasing severity of chorioamnionitis. Antenatal corticosteroids had no effect on median MMP-9 levels. Infants in the chorioamnionitis group were more likely to have chronic lung disease (CLD) develop (55% vs 28%, P
