It is difficult to insert long-term dialysis catheters after severe stenosis or occlusion of the internal jugular vein and innominate vein. We used REcanalisation and balloon-oriented puncture for Re-insertion of dialysis catheter in nonpatent central veins (REBORN) in seven patients with severe central venous lesions, and all patients were inserted with long-term dialysis catheters successfully. None had severe complications such as pneumothorax, hemothorax, or pulmonary embolism during operation. All catheters functioned well after postoperative follow-up of 2 months. REBORN provides a novel approach to establish difficult dialysis pathways.

INTRODUCTIONThe present study aimed to determine the impact of an extended infection control training programme, which was conducted for all interns posted to the Department of Paediatrics, on the incidence of paediatric intensive care unit (PICU)-acquired bloodstream infections (BSIs) in University Malaya Medical Centre, Malaysia.

METHODSThe development of nosocomial BSIs during the baseline period (1 January-31 October 2008) and intervention period (1 November-31 December 2009) was monitored. During the intervention period, all paediatric interns underwent training in hand hygiene and aseptic techniques for accessing vascular catheters.

RESULTSA total of 25 patients had PICU-acquired BSIs during the baseline period, while 18 patients had PICU-acquired BSIs during the intervention period (i.e. infection rate of 88 per 1,000 and 41 per 1,000 admissions, respectively). The infections were related to central venous catheters (CVCs) in 22 of the 25 patients who had PICU-acquired BSIs during the baseline period and 11 of the 18 patients who had PICU-acquired BSIs during the intervention period. Thus, the incidence rates of catheter-related BSIs were 25.2 per 1,000 CVC-days and 9.3 per 1,000 CVC-days, respectively (p < 0.05). The Paediatric Risk of Standardised Mortality III score was an independent risk factor for PICU-acquired BSIs and the intervention significantly reduced this risk.

CONCLUSIONThe education of medical interns on infection control, a relatively low-cost intervention, resulted in a substantial reduction in the incidence of PICU-acquired BSIs.

OBJECTIVETo explore the clinical efficacy and safety of the early use of urokinase in the prevention and treatment on tunneled hemodialysis catheter related fibrin sheaths.

METHODSThirty-eight hemodialysis patients with tunneled central venous catheter and good catheter function were randomly divided into experimental group and control group. Urokinase was given after 3 days of indwelling catheter in the experimental group and after the onset of catheter dysfunction in the control group. The catheter function, mean blood flow and venous pressure of dialysis, coagulation, and side effects in the two groups were observed for 6 months.

RESULTSThe rates of catheter dysfunction on the arterial side were 0.65% and 2.71% in the experimental group and control group, respectively (P<0.05), with catheter dysfunction rates on the vein side of 0.92% and 2.41%, respectively (P<0.05). Catheter dysfunction occurred for the first time at 87.9 ± 24.1 days in the experimental group, and at 31.3 ± 11.5 days in the control group (P<0.05). The mean blood flow showed no significant difference between the two groups at 1 month after tube insertion (P>0.05), but was higher in the experimental group at 3 and 6 months after the tube insertion (P<0.05). The mean venous pressure in two groups was similar 1 and 3 months after tube insertion (P>0.05), but was significantly lower in the experimental group at 6 months (P<0.05). Compared with control group, the experimental group showed significantly prolonged prothrombin time (P<0.05) but similar rest coagulation parameters. No serious drug-related side effects occurred in these two groups.

CONCLUSIONEarly use of urokinase is safe and effective for prevention and treatment of tunneled hemodialysis catheter-related fibrin sheaths with minimal side effects.

Advanced cancer patients with refractory ascites often do not respond to conventional treatments including dietary sodium restriction, diuretics, and repeated large volume paracentesis. In these patients, continuous peritoneal drainage by an indwelling catheter may be an effective option for managing refractory ascites with a relative low complication rate. Peritoneal catheter-induced complications include hypotension, hematoma, leakage, cellulitis, peritonitis, and bowel perforation. Although bowel perforation is a very rare complication, it can become disastrous and necessitates emergency surgical treatment. Herein, we report a case of a 57-year-old male with refractory ascites due to advanced liver cancer who experienced iatrogenic colonic perforation after peritoneal drainage catheter insertion and was treated successfully with endoscopic clipping.

OBJECTIVE: The purpose of this study was to determine the incidence and risk factors of infections associated with implantable venous access ports (IVAPs). MATERIALS AND METHODS: From August 2003 through November 2011, 1747 IVAPs were placed in our interventional radiology suite. One hundred forty four IVAPs were inserted in patients with hematologic malignancy and 1603 IVAPs in patients with solid tumors. Among them, 40 ports (23 women and 17 men; mean age, 57.1 years; range, 13-83) were removed to treat port-related infections. We evaluated the incidence of port-related infection, patient characteristics, bacteriologic data, and patient progress. Univariable analyses (t test, chi-square test, and Fisher's exact test) and multiple logistic regression analyses were used to determine the risk factors for IVAP related infection. RESULTS: Overall, 40 (2.3%) of 1747 ports were removed for symptoms of infection with an incidence rate of 0.067 events/1000 catheter-days. According to the univariable study, the incidences of infection were seemingly higher in the patients who received the procedure during inpatient treatment (p = 0.016), the patients with hematologic malignancy (p = 0.041), and the patients receiving palliative chemotherapy (p = 0.022). From the multiple binary logistic regression, the adjusted odds ratios of infection in patients with hematologic malignancies and those receiving palliative chemotherapy were 7.769 (p = 0.001) and 4.863 (p = 0.003), respectively. Microorganisms were isolated from 26 (65%) blood samples, and two of the most causative organisms were found to be Staphylococcus (n = 10) and Candida species (n = 7). CONCLUSION: The underlying hematologic malignancy and the state of receiving palliative chemotherapy were the independent risk factors of IVAP-related infection.

BACKGROUND/AIMS: The high mortality attributable to persistent methicillin-resistant Staphylococcus aureus (MRSA) bacteremia in spite of glycopeptide treatment has heightened the need for early detection and intervention with alternative agents. The purpose of this study was to determine the clinical characteristics of and risk factors for persistent MRSA bacteremia. METHODS: All first episodes of significant MRSA bacteremia at a 710-bed academic medical center from November 2009 through August 2010 were recorded. Blood cultures were conducted at 3 days and every 2 to 3 days thereafter until clearance. Clinical characteristics and outcomes were compared between persistent MRSA bacteremia (> or = 7 days) and nonpersistent MRSA bacteremia (< or = 3 days). RESULTS: Of 79 patients with MRSA bacteremia during the study period, 31 (39.2%) had persistent MRSA bacteremia. The persistent MRSA bacteremia group had significantly higher 30-day mortality than the nonpersistent MRSA bacteremia group (58.1% vs. 16.7%, p < 0.001). Multivariate analysis indicated that metastatic infection at presentation (odds ratio [OR], 14.57; 95% confidence interval [CI], 3.52 to 60.34; p < 0.001) and delayed catheter removal in catheter-related infection (OR, 3.80; 95% CI, 1.04 to 13.88; p = 0.004) were independent predictors of persistent MRSA bacteremia. Patients with a time to blood culture positivity (TTP) of < 11.8 hours were at increased risk of persistent MRSA bacteremia (29.0% vs. 8.3%, p = 0.029). CONCLUSIONS: High mortality in patients with persistent MRSA bacteremia was noted. Early detection of metastatic infection and early removal of infected intravascular catheters should be considered to reduce the risk of persistent MRSA bacteremia. Further studies are needed to evaluate the role of TTP for predicting persistent MRSA bacteremia.

OBJECTIVE: To determine the safety and usefulness of a two-tiered approach to balloon-occluded retrograde transvenous obliteration (B-RTO) as a treatment for large gastric varices after portal hypertension. MATERIALS AND METHODS: 50 patients were studied who underwent B-RTO for gastric varices between October 2004 and October 2011 in our institution. The B-RTO procedure was performed from the right femoral vein and the B-RTO catheter was retained until the following morning. Distribution of sclerotic agents in the gastric varices on fluoroscopy was evaluated in all patients on days 1 and 2. When distribution of sclerotic agents in the gastric varices on day 1 had been none or very scanty even though the volume of the sclerotic agent infused was above the acceptable level, a second infusion was administered on day 2. When distribution was satisfactory, the B-RTO catheter was removed. RESULTS: In 8 (16%) patients, little or no sclerotic agent infused on day 1 was distributed in the gastric varices. However, on day 2, sclerotic agents were distributed in all gastric varices. Mean volume of ethanolamine oleate-iopamidol infused on day 1 was 24.6 mL and was 19.4 mL on day 2. Gastric varices were well obliterated with no recurrence. Complications caused by the sclerotic agent such as pulmonary edema or renal insufficiencies were not seen. CONCLUSION: When gastric varices are very large, a strategy involving thrombosis of only the drainage vein on the first day followed by infusing the sclerotic agent on the following day might be effective and feasible.

While oral agents are currently suggested for the initial treatment of erectile dysfunction, penile prosthesis implantation (malleable or inflatable) is accepted as a third-line therapy if intracorporeal injection and intraurethral treatment fail as a secondary choice. Urethral erosion of the malleable penile prosthesis is a well-known complication, mostly due to the indwelling catheter. We report a case of urethral erosion of the malleable penile prosthesis after 23 years. The patient was a 45-year-old man without any underlying risk factors. He subsequently underwent a unilateral rod extraction under regional anaesthesia. It appears that urethral erosion of penile prostheses can appear at any time post operation, without any known facilitative factors and in any age group. Furthermore, simple office manoeuvres may not be possible in some patients.
