Abstract
BACKGROUND IVI epoprostenol is the only therapy for pulmonary arterial hypertension (PAH) with a randomized controlled trial demonstrating improved survival, when used as first-line monotherapy. In Australia it is used as salvage therapy for those failing treatment with other targeted therapies or presenting in World Health Organization functional class (FC) IV. AIMS Report experience with IVI epoprostenol, administered as salvage therapy for the treatment of adults with PAH in a single Australian PAH centre. METHODS Retrospective case series of all patients commenced on IVI epoprostenol for PAH, between 2002 and 2010. Review of case notes with collection of data at baseline and after treatment, including FC, 6-min walk test (6MWT), right ventricular systolic pressure (RVSP) on echocardiogram, patient survival and treatment complications. Change in indices was assessed using the Wilcoxon Sign Rank Test and is expressed as median (inter-quartile range). RESULTS A total of 23 patients was included. Treatment was generally well tolerated with few major complications. At the end of the study period, nine patients were successfully bridged to transplant, five had a sustained response to IVI epoprostenol, six had an incomplete response but were clinically stabilized, two died awaiting transplant and one died who was not a candidate for transplantation. Overall, when measured at best level post initiation of IVI epoprostenol, there were significant improvements in FC -1 [0 to -1] (P < 0.0001), 6MWT (m) +117 [70-264] (P= 0.002) and RVSP (mmHg) -7.0 [4.0 to -45] (P= 0.03). CONCLUSION Findings support efficacy of epoprostenol as salvage therapy for patients with PAH.

Abstract
BACKGROUND This study compares the outcomes and survivals between two central venous access port systems. STUDY DESIGN Medical records from 298 cancer patients who had received open-end (Deltec, N = 159) or closed-end (Groshong, N = 139) port catheter insertions were retrospectively reviewed. METHODS The infection, thrombosis, and surgical complication rates (chi-square test), as well as mean catheter-indwelling-days (t-test) were compared. Kaplan Meier analysis and stratified log rank test were used to compare actuarial survival rates. Cox proportion hazard model was applied to analyze the outcomes predictors. RESULTS The total catheter-indwelling-day was 116,603 days in general for this cohort. The Groshong catheters (569 +/- 386.1 days) had longer (P < 0.001) mean catheter-indwelling-day than did Deltec catheters (239 +/- 235.6 days). But the per 1,000 catheter day infection (Deltec 0.18, Groshong 0.16), thrombosis (Deltec 0.07, Groshong 0.06), and surgical complication rates (Deltec 0.07, Groshong 0.02) were equivalent (P > 0.05) between two groups. Patients with leukemia were at higher risk (odds ratio 13.4, P = 0.009) to develop adverse events. However, two types of catheters had similar actuarial survival rates at end of follow up (P > 0.05). CONCLUSION We found infection, thrombosis occlusion, surgical complication, and actuarial device survival rates were similar between Deltec and Groshong groups. Hematogenous malignancy was a risk factor for catheter failure.

Abstract
OBJETIVO: Analisar se a presença de neoplasia hematológica acarreta maior risco de complicações para inserção de cateteres totalmente implantáveis e se há diferença de tempo cirúrgico quando o procedimento é realizado por punção ou dissecção venosa. MÉTODO: Foram avaliados 68 pacientes com neoplasia internados no Hospital Santa Rita de Porto Alegre entre fevereiro de 1998 e dezembro de 1999, os quais necessitavam de acesso venoso central para tratamento quimioterápico, sendo 48 do sexo feminino e com idade média de 55,6 anos. Desses, 31 apresentavam neoplasia hematológica. RESULTADOS: Complicações pós-operatórias ocorreram em 13 pacientes (19%), sendo elas: obstrução do sistema (7%), hematoma (6%) e infecção (6%), não havendo diferença quanto ao tipo de neoplasia (p = 0,56). Foram realizadas dissecção e punção venosa em 30 e 38 pacientes, respectivamente, sem diferença em relação ao tempo de implantação do cateter (p = 0,42). CONCLUSÃO: Neoplasias hematológicas não aumentaram o risco de complicações quando do uso de cateteres totalmente implantáveis no presente estudo, além disso, ambas as técnicas cirúrgicas - dissecção ou punção - são exeqüíveis, haja visto o tempo cirúrgico semelhante entre elas, desde que sejam respeitados o valor sérico mínimo de plaquetas (50.000/mL) e a técnica cirúrgica apropriada, com hemostasia rigorosa e curativo compressivo.

Abstract
PURPOSE Implantable venous access devices (IVADs), either centrally or peripherally implanted, have become increasingly popular in children with hemophilia to assist in the early treatment of bleeding episodes and in the prevention of arthropathy. Their use has been associated with complications including thrombosis, thrombophlebitis, and infection. We attempted to better define whether the benefits associated with IVADs in this population outweight the associated risks. PATIENTS AND METHODS We studied the medical records of 35 children from the University of Minnesota's Comprehensive Hemophilia Center who received IVADs between 1992 and 1996. RESULTS There was no bleeding or thrombophlebitis associated with IVADs in our population. One patient required removal of a central IVAD due to thrombosis. The central IVADs were associated with local infection and bacteremia rates of 3% and 33%, respectively. The rates of local infection and bacteremia associated with peripheral IVADs were both 25%. The majority of infections were cleared with antibiotics, and ports remained intact. Both types of IVADs were associated with a high patient/parent satisfaction. CONCLUSION Despite being associated with a significant incidence of infection, we believe the benefits of IVADs for children with hemophilia and their families outweigh the risks. Possible explanations for the observed infection rates are discussed.

Abstract
BACKGROUND Semipermanent tunnelled silicone rubber Hickman catheters are widely used to provide durable central venous access for patients with cancer or haematological disease. AIMS To document the frequency and severity of Hickman catheter related adverse events and to identify predisposing factors. METHODS A retrospective review was undertaken of 153 sequential Hickman catheters inserted into patients receiving treatment for cancer or haematological disease. All Hickman catheters were inserted percutaneously in a radiology department under local anaesthesia and fluoroscopic control. The exact position of the catheter tip was determined by reviewing post-insertion radiographs. RESULTS The median duration of catheter use was 55 days (range one-650). Complications led to the removal of 32% of catheters. Exit site infection complicated 22% of catheters, septicaemia 7%, migration or dislodgment 7%, and venous thrombosis 8%. Complications were more common in male patients (exit site infection and catheter loss), in patients with acute leukaemia (septicaemia) and in obese patients (catheter migration). Left sided catheters caused more venous thrombosis and were more likely to malfunction or block. Left sided catheters required removal more frequently than right sided catheters. Termination of the Hickman catheter within the high superior vena cava (SVC) resulted in loss of function earlier when compared to termination with the low SVC or right atrium (RA). CONCLUSIONS Right-sided Hickman catheters terminating in the low SVC/RA offer the best chance of durable function. The use of subcutaneously tunnelled catheters in obese patients poses unique problems with catheter migration. Vigilance in the placement and care of Hickman catheters remains essential.

Abstract
BACKGROUND Bacterial infection is a major cause of morbidity and mortality in neutropenic patients. AIMS (1) To review patterns and trends in bacterial infections in three cohorts of febrile neutropenic patients managed by a single unit over a seven year period. (2) To relate any changes to the use of central venous (Hickman's) catheters and high-dose cytosine arabinoside chemotherapy. METHODS Retrospective review of the results of initial bacteriological work-up performed on 344 episodes of febrile neutropenia. The three cohorts were 1986-87 (n = 102), 1989-90 (n = 92) and 1991-92 (n = 150). RESULTS (1) The ratio of gram-negative to gram-positive bacteraemias fell from 1.36 in the first cohort to 1.05 in the second and 0.40 in the third (p = 0.03). There was a fall in both percentage and number of gram-negative isolates coupled with a rise in the frequency of gram-positive isolates. (2) Coincidentally there was a rise in the frequency of positive cultures from Hickman catheter entry wounds and an increasing frequency of simultaneous isolation of the same organism from the catheter entry site and the blood. The types of organisms isolated from catheter entry wounds showed a trend towards fewer gram-negative and more gram-positive. (3) A relationship was observed between the use of high-dose cytosine arabinoside chemotherapy and the incidence of bacteraemia (p = 0.025) but not with the change in types of organisms. CONCLUSIONS Over seven years we have documented a major change in the types of infections, particularly bacteraemias, seen in febrile neutropenic patients. In our institution the more widespread use of intravenous catheters and high-dose cytosine arabinoside chemotherapy have been identified as two possible contributing factors.

Abstract
Long-term venous access using Hickman catheters and implantable subcutaneous ports is a well established technique. These devices have customarily been inserted via the internal jugular, subclavian or cephalic veins. On occasions, these routes may be unavailable. This article reviews the outcome of 53 prolonged venous access catheters (39 Hickmans and 14 catheters attached to implantable ports) inserted percutaneously via the external iliac vein into 37 patients over a period of 5.7 years. The indications for insertion were chemotherapy (40%), total parenteral nutrition (36%), intravenous antibiotics (13%), poor venous access (7%) and bone marrow transplantation (4%). The main reasons for use of the external iliac vein were thrombosis of the subclavian veins or superior vena cava and subclavian central line sepsis. The only complication of insertion was one inadvertent puncture of the external iliac artery. Twenty-seven catheters (51%) remained complication free and functioning for the time for which they were required. Four catheters (7%) are still functioning in situ having been present for 1-5 years. Sixteen catheters (30%) became infected, with a 17% incidence of septicaemia. Venous thrombosis was associated with three catheters (6%). Catheters remained in situ for a median period of 30 days (range 5-569 days). The authors conclude that long-term venous access using percutaneous external iliac vein insertion is a useful technique when other routes are unavailable, but there is a relatively high incidence of catheter-related sepsis.

Abstract
One hundred and forty silicone catheters were inserted in 127 patients for long-term intravenous access with a cumulative follow-up time of 21,125 catheter-days (58 patient-years). Fifty-six patients had acquired immunodeficiency syndrome (AIDS); 44 were not AIDS patients and were receiving ambulatory home parenteral nutrition, whereas the remaining 27 did not have AIDS and were receiving home antibiotic therapy. Patients had a mean of 1.1 catheters inserted, and the rate of Hickman catheter-related sepsis was 0.18 per 100 catheter days or 0.6 septic episodes per patient year of treatment. Catheter-related sepsis was higher in AIDS patients (p < .01) and in patients receiving parenteral nutrition (p < .05) compared with those receiving antibiotic therapy. Prior catheter infection and AIDS were the most significant predictors of catheter infection (p < .01). Staphylococcus aureus was the most commonly isolated pathogen (61%) in AIDS patients. Fever (p < .001) and relative leukocytosis (p < .02) were the most common signs of infection. Only 14 infected catheters (37.8%) were salvaged by antibiotic therapy after the initial infection episode, and 6 of these catheters (42.9%) had recurrent multiple infections. In addition, inflammatory bowel disease was found to be a risk factor for venous thrombosis (p = .018). We conclude that because immunocompromised patients have a high risk of infection, catheter-related sepsis in these patients should be treated by catheter removal and antibiotics.

Abstract
PURPOSE Determination of outcome and prognostic variables associated with Staphylococcus aureus bacteremia in patients with Hickman catheters. PATIENTS AND METHODS At the University of Washington Medical Center, 37 patients with Hickman catheters and S. aureus bacteremia were studied by retrospective chart review. Clinical features associated with each episode of infection were determined, and the relationships among clinical features, therapy, and outcomes were explored. RESULTS Only 18% of all Hickman catheter-associated S. aureus bacteremias and only 10% of those cases with exit site infections were cured without catheter removal. In seven of 41 episodes (17%), death or bacteremic relapse occurred. The best prognosis was found in infections with a low blood culture colony count (less than 1 colony/mL). CONCLUSION Hickman catheter-associated bacteremia due to S. aureus has a worse prognosis than other Hickman catheter-associated bacteremias. Early catheter removal should be considered except in cases with a remote, noncatheter focus of infection or in infections with no catheter-related physical signs and blood culture colony counts of less than 1/mL.

Abstract
One hundred and two patients with neutropenia (less than 1 x 10(9)/L) secondary to primary hematological disorders or chemotherapy for hematological malignancies were prospectively randomised, upon the development of fever or other signs of infection, to receive empirical antibiotic treatment with either ceftazidime (+/- flucloxacillin) (n = 52) or azlocillin plus amikacin (+/- flucloxacillin) (A&A, n = 50). The two groups were equivalent with respect to clinical and laboratory parameters prior to antibiotic therapy and flucloxacillin was added to approximately 25% of the patients in each group on the clinical suspicion of Gram positive infection. When assessed at 96 hours, the complete response rates were 59.6% for the ceftazidime treated patients and 44% for A&A treated patients. Partial response rates were 17% and 20% respectively. This difference was not statistically significant. Eight patients died whilst on the trial, three of those initially randomised to ceftazidime and five initially randomised to A&A. Moderate to severe hypokalemia was encountered significantly less often in the ceftazidime treated group (p less than 0.01), whilst other parameters of toxicity were equivalent. No primary or acquired resistance to ceftazidime was encountered. Separate analysis of those patients who did not receive flucloxacillin yielded identical results. We conclude that ceftazidime (+/- flucloxacillin) is as efficacious as azlocillin plus amikacin (+/- flucloxacillin) in the empirical antibiotic management of such patients and is associated with a lower incidence of moderate to severe hypokalemia.

Abstract
When used wisely, central venous catheters are capable of providing vital circulatory access in any patient with a remarkably low risk of infection or major complication. Tunneled silicone catheters are the route of choice for long-term or outpatient use, particularly for oncology or TPN patients; insertion of such a catheter should occur early in the hospitalization of a newly diagnosed patient on chemotherapy. The greatest experience has accrued with the cuffed silicone catheters (for example, Broviac), but the totally implantable devices (for instance, Port-a-cath) may become the device of choice in pediatric outpatients. For infants, small, percutaneously inserted noncuffed silicone catheters appear to offer the greatest safety. Among acute care patients, percutaneous plastic central venous catheters fulfill a vital role but represent an important source of infection. Scrupulous technique, the minimizing of manipulation, and a readiness to replace the catheter at any suggestion of trouble are important to achieving the best results. Within a given design, it is generally best to use the smallest diameter catheter capable of performing the desired tasks. However, on the basis of currently available data, there need be no hesitation to use a multilumen catheter if the care of the patient demands multiple access ports. The various silicone catheters can usually be left in place while infection is treated, although fungal and certain other infections are more likely to require catheter removal. Percutaneous plastic catheters should be removed or changed over a wire if infection is suspected; if tip culture of the removed catheter is positive, and the catheter was replaced over a wire, then the replacement catheter should be promptly removed.

Abstract
An immunocompromised patient with an indwelling Hickman catheter developed Mycobacterium neoaurum bacteremia. This rapidly growing mycobacterium was previously isolated from soil, dust, and water but has not been described as a human pathogen. The infection responded to therapy with cefoxitin and gentamicin. It was not necessary to remove the Hickman catheter.
