What Italian PICU Healthcare Providers Think About Donation After Cardiocirculatory Determination of Death: A National Survey.

BACKGROUND: Italy presently does not have a pediatric organ donation program after cardiocirculatory determination of death (pDCDD). Before implementing a pDCDD program, many centers globally have conducted studies on the attitudes of pediatric intensive care unit (PICU) staff. This research aims to minimize potential adverse reactions and evaluate the acceptance of the novel donation practice. METHODS: We conducted an electronic and anonymous survey on attitudes toward pDCDD among healthcare professionals (HCPs) working at eight Italian PICUs. The survey had three parts: (I) questions about general demographic data; (II) 18 statements about personal wishes to donate, experience of discussing donation, and knowledge about donation; (III) attitudinal statements regarding two pediatric Maastricht III scenarios of organ donation. RESULTS: The response rate was 54.4%, and the majority of respondents were nurses. Of those who responded, 45.3% worked in the Center, 40.8% in the North, and 12.8% in the South of Italy. In total, 93.9% supported pediatric organ and tissue donation, 90.3% supported donation after neurological determination of death (DNDD), 78.2% supported pDCDD, and 69.7% felt comfortable about the idea of participating in pDCDD on Type III patients, with a higher percentage of supportive responses in the Center (77.2%) than in the North (65.1%) and South (54.5%) of Italy (p-value < 0.004). Concerning scenarios, 79.3% of participants believed that organ retrieval took place in a patient who was already deceased. Overall, 27.3% considered their knowledge about DCDD to be adequate. CONCLUSIONS: Our study provides insight into the attitudes and knowledge of PICU staff members regarding pDCDD in Italy. Despite a general lack of knowledge on the subject, respondents showed positive attitudes toward pDCDD and a strong consensus that the Italian legislation protocol for determining death based on cardiocirculatory criteria respects the "dead donor rule." There were several distinctions among the northern, central, and southern regions of Italy, and in our view, these disparities can be attributed to the varying practices of commemorating the deceased. In order to assess how practice and training influence the attitude of PICU staff members, it would be interesting to repeat the survey after the implementation of a program.

Inferior vena cava surgical cannulation for infants needing veno-venous extracorporeal membrane oxygenation.

INTRODUCTION: Femoral cannulation for veno-venous extracorporeal membrane oxygenation is challenging in infants because of the diameter of the vein. CASE REPORT: Prolonged ECMO support (67 days) was necessary for an 8-month-old (8 kg) girl with acute respiratory distress syndrome that was caused by H1N1 influenza. After 30 days on ECMO support and using a single 16 Fr double-lumen cannula (internal jugular vein), a second cannula was necessary to ensure adequate flow. This second 12 Fr single-lumen cannula was surgically placed through the right common iliac vein. An excellent flow profile was then achieved and ECMO continued successfully for 37 more days. DISCUSSION: As a lifesaving option, this double caval configuration successfully optimized the flow profile and oxygenation, outweighing the related risks. CONCLUSION: In small children, a surgical approach to the inferior vena cava can be considered safe, especially in those cases where there is a shortage of adequate cannulas, or when central venous access is difficult.

Real-time ultrasound-guided placement of a pigtail catheter in supine position for draining pleural effusion in pediatric patients who have undergone liver transplantation.

PURPOSE: Ultrasound (US) guidance is currently used for placement of wire-guided thoracic drains, and its use is associated with a decreased risk of complications. However, most studies conducted to date in this field have been performed on adult patients. The aim of this study was to report the technical success and complication rates observed during real-time US-guided placement of a thoracic pigtail catheter in pediatric liver-transplant recipients with symptomatic pleural effusion. METHODS: This was a single-center retrospective review of the clinical records and images from pediatric liver-transplant patients with symptomatic pleural effusion who had undergone real-time US-guided pleural-space puncture followed by placement (via the Seldinger technique) of a pigtail catheter for drainage, between May 2006 and June 2014. RESULTS: We identified 25 patients who had undergone 41 pigtail catheter-placement procedures during the study period. The patients' mean age (± SD) was 4.2 ± 3.9 years (range, 2 months to 16 years), and their mean weight was 14.2 ± 7.2 kg (range, 4.5-33 kg). Seventeen procedures had been performed in the intensive care unit, and 8, in patients undergoing mechanical ventilation. Twelve of the 41 procedures had been performed in patients with altered hemostasis (ie, platelet count < 50 × 10(3) /µl and/or international normalized ratio > 1.5). The size of the pigtail catheters ranged from 5 F to 8.5 F. The technical success rate was 100%, with no major complications such as pneumothorax or hemothorax. Accidental dislocation of the catheter occurred in four patients (9%) over 3-10 days after the first procedure. CONCLUSIONS: In our experience, real-time US-guided pleural-space puncture, performed at bedside, with the patient in the supine position, followed by placement of a pigtail catheter for drainage of effusion, is safe to use and has a high rate of technical success in pediatric patients. © 2015 Wiley Periodicals, Inc.

Comparison between radiation exposure levels using an image intensifier and a flat-panel detector-based system in image-guided central venous catheter placement in children weighing less than 10 kg.

BACKGROUND: Ultrasound-guided central venous puncture and fluoroscopic guidance during central venous catheter (CVC) positioning optimizes technical success and lowers the complication rates in children, and is therefore considered standard practice. OBJECTIVE: The purpose of this study was to compare the radiation exposure levels recorded during CVC placement in children weighing less than 10 kg in procedures performed using an image intensifier-based angiographic system (IIDS) to those performed in a flat-panel detector-based interventional suite (FPDS). MATERIALS AND METHODS: A retrospective review of 96 image-guided CVC placements, between January 2008 and October 2013, in 49 children weighing less than 10 kg was performed. Mean age was 8.2 ± 4.4 months (range: 1-22 months). Mean weight was 7.1 ± 2.7 kg (range: 2.5-9.8 kg). The procedures were classified into two categories: non-tunneled and tunneled CVC placement. RESULTS: Thirty-five procedures were performed with the IIDS (21 non-tunneled CVC, 14 tunneled CVC); 61 procedures were performed with the FPDS (47 non-tunneled CVC, 14 tunneled CVC). For non-tunneled CVC, mean DAP was 113.5 ± 126.7 cGy cm(2) with the IIDS and 15.9 ± 44.6 cGy · cm(2) with the FPDS (P < 0.001). For tunneled CVC, mean DAP was 84.6 ± 81.2 cGy · cm(2) with the IIDS and 37.1 ± 33.5 cGy cm(2) with the FPDS (P = 0.02). CONCLUSION: The use of flat-panel angiographic equipment reduces radiation exposure in small children undergoing image-guided CVC placement.

Post-crisis debriefing: A tool for improving quality in the medical emergency team system.

OBJECTIVES: To examine clinicians' perception of quality of technical and non-technical response to emergencies and application of post crisis debriefing. DESIGN: Descriptive, anonymous, self-reporting survey on the needs and perception of a post-crisis debriefing implementation. SETTING: Multi-specialist medical institute in Italy focused on solid organ transplantation and organ failure support. MAIN OUTCOMES: Perception of application of guidelines and evaluation of debriefing implementation during in-hospital emergencies. RESULTS: Response rate to the survey was 25% (148 health care workers). Of all respondents, 86% were employed >10 years, 75% were involved in ≤5 emergencies over the previous year. Resuscitation guidelines were considered fully applied by 55%; 64% of respondents considered the teaching programme as sufficient. Of all participants, 97% were aware of the importance of teamwork dynamics, 79% were aware of the importance of the personal performance, and 52% considered emergencies as valid opportunities for professional growth. Leadership was considered important by 45% of respondents; debriefing implemented by 41%, and considered a potentially useful tool by 85%. CONCLUSION: Post-crisis debriefing is a way to diffuse self-reflective and life-long learning culture; it is perceived as a powerful tool for improving quality of the rapid response system by the vast majority of those surveyed.

A simple noninvasive score predicts gastroesophageal varices in patients with chronic viral hepatitis.

BACKGROUND: Guidelines recommend upper endoscopic screening of cirrhotic patients for gastroesophageal varices. Cirrhosis is not always distinguishable from chronic hepatitis. GOALS: To identify low-risk patients who can be spared upper endoscopy irrespective of a diagnosis of cirrhosis. STUDY: We evaluated 13 nonendoscopic variables as predictors of esophagogastric varices in 254 patients with hepatitis B or hepatitis C-related chronic liver disease who underwent upper endoscopy. RESULTS: Any size varices occurred in 30.3% (77/254), and large varices in 12.2% of patients (31/254). Age >50 years [odds ratio (OR): 11.29; 95% confidence interval (CI): 2.33-54.67], platelet count <150,000/mmc (OR: 4.40; 95% CI: 1.85-10.45), albumin <3.6 g/dL (OR: 2.99; 95% CI: 1.31-6.79), and aspartate aminotransferase/alanine aminotransferase ratio >1 (OR: 2.83; 95% CI: 1.26-6.34) independently predicted varices by logistic regression. Using a score based on age >50 years, platelets <150,000/mmc, and aspartate aminotransferase/alanine aminotransferase ratio >1 (1 point/predictor), only 3.2% of patients with a score <2 had varices, all small. CONCLUSIONS: Patients with chronic viral hepatitis and a score <2 need not undergo upper endoscopy, as they are unlikely to have large varices. Because about 50% of our patients had this score, 50% of upper endoscopies may be safely avoided.

Iron depletion before HCV antiviral therapy: a pilot, randomized, controlled trial.

It is not known whether iron depletion before pegylated IFN or combination treatment improves sustained virological response (SVR) rate in patients with chronic hepatitis C, despite its use in clinical practice in this setting. We aimed to investigate whether blood letting improves the efficacy (SVR) and tolerability of PEG-IFNalpha2b + Ribavirin in chronic hepatitis C patients. Patients with chronic hepatitis C and ferritin >100 ng/mL were randomized to: (1) repeated phlebotomies to obtain a ferritin level <50 ng/mL followed by pegylated-Interferon alpha2b + ribavirin (active arm); or (2) pegylated-Interferon alpha2b + ribavirin (control arm). Primary endpoint was SVR rate, secondary endpoint was frequency of clinical and laboratory grade 3-4 adverse events. Thirty-three patients were enrolled in the study (19 in active arm, 14 in control arm). The 19 patients in the active arm underwent a median of 5 phlebotomies (range: 1-9) to achieve the targeted ferritin (<50 ng/mL). Phlebotomies significantly reduced ferritin, iron, transferrin saturation, aspartate aminotransferase, alanine aminotransferase, and hemoglobin levels. Platelet count significantly increased, whereas HCV-RNA levels remained unchanged. After antiviral therapy overall SVR was 31.6% in active arm and 21.4% in control arm (P = 0.698). Considering only the 18 patients who were naive to antiviral therapy, SVR was 60% in active arm versus 25% in control arm (P = 0.188). Tolerability, drug dose reduction or withdrawal were similar in the two arms. In conclusion phlebotomies do not increase the overall efficacy of antiviral therapy. However, the strong trend to higher SVR in naive patients undergoing phlebotomies warrants further investigation.

Button battery removed from the stomach resulting in a missed aortoesophageal fistula - a multidisciplinary approach to rescuing a very young patient: a case report.

BACKGROUND: While coins are still the most common foreign bodies swallowed by children, ingestion of batteries has become more frequent among children due to the increasing access to electronic toys and devices. Coin battery ingestion is potentially life threatening for children. Aortoesophageal fistula is the most common cause of death in children who have swallowed coin batteries, and there have not been any reported survivors. CASE PRESENTATION: A 3-year-old Caucasian girl presented to the emergency room of a community hospital complaining of abdominal pain. An abdominal X-ray showed a coin lithium battery located in the fundus of her stomach, and she was transferred to a referral pediatric hospital. In the following hours she developed massive hematemesis and severe hypovolemic shock. An emergency laparotomy was attempted, and the coin battery was removed. The initial surgery and multiple blood transfusions did not, however, improve the clinical situation. She was then referred to our tertiary referral center, where a multidisciplinary team decided to attempt a combined angiographic and endoscopic approach to resolve a life-threatening aortoesophageal fistula. A 3-year follow-up was uneventful. CONCLUSIONS: Coin batteries are designed for a wide variety of small appliances, such as hearing aids, watches, remote controls, and toys. Although a change in the clinical approach to battery ingestion is needed to avoid misdiagnosis or delayed treatment, primary prevention of battery ingestion would be even more effective than an improved treatment.

Retrospective analysis of a new antibiotic chemoprophylaxis regimen in 170 patients undergoing endoscopic endonasal transsphenoidal surgery.

BACKGROUND: The aim of this study is to evaluate the rate of infectious complications post endoscopic transspheinodal neurosurgery in patients receiving a new antibiotic chemoprophylaxis regimen. METHODS: Clinical records of 170 patients who received prophylaxis with a third-generation cephalosporin plus aminoglycoside (160 cases) or alone (10 cases) were retrospectively analyzed. Twenty-eight patients (16.4%) had CSF leakage. The postsurgical follow-up ranged from 3 months to 4 years. RESULTS: Of 170 patients, 2 (1.17%) developed infectious complications: 1 case of meningitis by Staphylococcus epidermidis and 1 case of sphenoid sinusitis (without microbiological diagnosis). In addition, asymptomatic sphenoid sinusitis was diagnosed in 2 other patients. The cost ranged from 22.50 to 33.34 euros/d. CONCLUSIONS: The rate of infectious complications was very low in patients receiving prophylaxis with a third-generation cephalosporin plus aminoglycoside or alone; because of the broad-spectrum of antibiotics and their high cost, this regimen could be used in at-risk patients (eg, smokers, patients with cerebrospinal leak, or patients with Cushing diseases).

Ante situm liver resection with inferior vena cava replacement under hypothermic cardiopolmunary bypass for hepatoblastoma: Report of a case and review of the literature.

INTRODUCTION: Hepatoblastoma with tumour thrombi extending into inferior-vena-cava and right atrium are often unresectable with an extremely poor prognosis. The surgical approach is technically challenging and might require major liver resection with vascular reconstruction and extracorporeal circulation. However, which is the best surgical technique is yet unclear. PRESENTATION OF CASE: A 11-months-old boy was referred for a right hepatic lobe mass(90×78mm) suspicious of hepatoblastoma with tumoral thrombi extending into the inferior-vena-cava and the right atrium, bilateral lung lesions and serum alpha-fetoprotein level of 50.795IU/mL. After 8 months of chemotherapy (SIOPEL 2004-high-risk-Protocol), the lung lesions were no longer clearly visible and the hepatoblastoma size decreased to 61×64mm. Thus, ante situm liver resection was planned: after hepatic parenchymal transection, hypothermic cardiopulmonary bypass was started and en bloc resection of the extended-right hepatic lobe, the retro/suprahepatic cava and the tumoral trombi was performed with concomitant cold perfusion of the remnant liver. The inferior-vena-cava was replaced with an aortic graft from a blood-group compatible cadaveric donor. The post-operative course was uneventful and after 8 months of follow-up the child has normal liver function and an alpha-fetoprotein level and is free of disease recurrence with patent vascular graft. CONCLUSIONS: We report for the first time a case of ante situ liver resection and inferior-vena-cava replacement associated with hypothermic cardiopulmonary bypass in a child with hepatoblastoma. Herein, we extensively review the literature for hepatoblastoma with thumoral thrombi and we describe the technical aspects of ante situm approach, which is a realistic option in otherwise unresectable hepatoblastoma.

Hemolytic anemia during pegylated IFN-alpha2b plus ribavirin treatment for chronic hepatitis C: ribavirin is not always the culprit.

A 53-year-old woman admitted to our department for histologically proven chronic hepatitis C had previously been treated with pegylated interferon-alpha2b (PEG-IFN) plus ribavirin. Combination therapy had been withdrawn after 5 weeks because of severe anemia (hemoglobin 8.2 g/dl) despite a reduction in ribavirin dose. A second liver biopsy showed moderate chronic hepatitis with portoportal and portocentral bridges (Ishak score: grading 14/18, staging 4-5/6). Consequently, the patient was retreated with 1.5 microg/kg body weight weekly PEG-IFN and 1000 mg/day ribavirin. Ribavirin was withdrawn about 3 months later because of anemia. After 1 month of PEG-IFN alone, hemoglobin had decreased further to reach 7.9 g/dl; consequently IFN was stopped. An elevated reticulocyte count, indirect bilirubin concentration, and lactic dehydrogenase (LDH) concentration, and a positive direct Coombs test (IgG3, C3d also for panagglutinant irregular antibodies on eluate) led us to diagnose autoimmune hemolytic anemia (AHA). The patient received 1 mg/kg body weight/day prednisone, and all parameters normalized within 20 days. This is the first case of IFN-related AHA during PEG-IFN plus ribavirin therapy. Physicians should be aware that PEG-IFN can be the cause of AHA during a ribavirin-containing regimen for chronic hepatitis C.

Severe Acute Respiratory Failure due to Inhalation of Baby Powder and Successfully Treated with Venous-Venous Extracorporeal Membrane Oxygenation.

Accidental inhalation of powder is a potential problem for infants. The clinical effects of inhaling powder depend on the powder contents, degree of aspiration, and the child's underlying systemic response. We present a case of accidental inhalation of rice starch powder in a 17-month-old girl, which led to severe acute respiratory distress syndrome responsive to conventional treatment, ultimately requiring venous-venous extracorporeal membrane oxygenation.

Pernicious anemia during IFN-alpha treatment for chronic hepatitis C.

Some latent diseases, such as immune disorders, can appear during interferon-alpha (IFN-alpha) therapy. These disorders are difficult to predict because of their low prevalence in the general population. We describe a case of pernicious anemia (PA) in a patient affected by chronic hepatitis C and macrocytosis during IFN-alpha therapy. Hemoglobin (Hb) concentration reached 7.3 g/dl. Anti-intrinsic factor (IF) antibodies were present, but not antiparietal cell antibodies (APCA). Suspension of IFN-alpha and administration of vitamin B(12) resulted in normal Hb concentrations. This case is the first instance of early PA (at the second month of IFN therapy) in a patient affected by chronic hepatitis C. The only other case of PA in a patient affected by hepatitis C virus (HCV) infection occurred during the second year of maintenance IFN therapy. We recommend that particular attention be paid to such clinical and laboratory conditions as macrocytosis in administering IFN-alpha therapy for chronic hepatitis C.

Differences between semen and plasma of nucleoside reverse transcriptase resistance mutations in HIV-infected patients, using a rapid assay.

The emergence of HIV-resistant strains generally occurs during treatment failure. A high rate of viral replication, low patient adherence to therapy, poor drug absorption or increased drug metabolism may be related to treatment failure and favour the onset of resistance. Recently, despite the absence of detectable HIV viral load in plasma, the importance of the persistence of HIV replication in other reservoirs has been underlined. Paired semen and plasma specimens stored from HIV male patients were tested using the LiPA assay, detecting genotype mutations related to Nucleoside Reverse Transciptase Inhibitors (NRTI) resistance. Overall, 32 paired semen and plasma samples were analyzed. The presence of HIVsequences was determined in 13 paired specimens (40.6%). Sixteen semen and 10 plasma specimens failed to amplify. At least one mutation was identified in the plasma of 77.8% of treated and 50.0% of naive patients. Similarly, mutations were identified in the semen of 66.7% of treated and 50.0% of untreated patients. Different mutation patterns between the two compartments were found in 46.2% of patients. The use of rapid assessment of HIV resistance in plasma and semen may be useful in some situations, such as HIV infection transmitted by sexual contact. Our data reinforce the evidence that, regarding HIV replication, the male genital tract must be considered as a separate compartment from the plasma.

Protein Fv produced during viral hepatitis is an endogenous immunoglobulin superantigen activating human heart mast cells.

Protein Fv, an endogenous protein produced in the liver, is released in biological fluids during viral hepatitis. Acute and chronic viral hepatitis can be associated with cardiovascular derangements. Protein Fv induced the release of histamine, tryptase and the de novo synthesis of prostaglandin D(2) and cysteinyl leukotriene C(4) from mast cells isolated from human heart tissue (HHMC). Protein Fv absorbed with protein A-Sepharose coated with polyclonal IgG did not induce histamine secretion. The maximal percent histamine secretion induced by protein Fv correlated (r(s) = 0.60; p < 0.05) with that induced by anti-IgE, whereas there was no correlation between the release caused by proteins Fv and C5a. Preincubation of HHMC with protein Fv or anti-IgE caused complete cross-desensitization to subsequent challenge with heterologous stimulus. HHMC from which IgE had been dissociated no longer released histamine in response to anti-IgE and protein Fv. A human monoclonal IgE blocked both anti-IgE- and protein Fv-induced release. Three human monoclonal IgM V(H)3(+) inhibited protein-Fv-induced secretion of histamine from HHMC, whereas monoclonal IgM V(H)6(+) did not inhibit the release induced by protein Fv. Protein Fv acts as an endogenous immunoglobulin superantigen by interacting with the V(H)3 domain of IgE to induce the release of mediators from HHMC.
