The occurrence of pressure injuries and related risk factors in patients undergoing extracorporeal membrane oxygenation for respiratory failure: A retrospective single centre study.

INTRODUCTION: Limited data is available regarding the incidence of pressure injuries in patients who have undergone Extracorporeal Membrane Oxygenation (ECMO), a life-saving technique that provides respiratory support for hypoxemia that does not respond to conventional treatment. AIM: To assess the incidence of pressure injuries and identify the risk factors in Acute Respiratory Distress Syndrome patients receiving ECMO. METHODS: A retrospective observational study utilizing prospectively collected data was performed in an Italian intensive care unit, between 1 January 2012 and 30 April 2022 enrolling all consecutive patients with Acute Respiratory Distress Syndrome who underwent ECMO. RESULTS: One hundred patients were included in this study. 67 patients (67%) developed pressure injuries during their intensive care unit stay, with a median of 2 (1-3) sites affected. The subgroup of patients with pressure injuries was more hypoxic before ECMO implementation, received more frequent continuous renal replacement therapy and prone positioning, and showed prolonged ECMO duration, intensive care unit and hospital length of stay compared to patients without pressure injuries. The logistic model demonstrated an independent association between the pO2/FiO2 ratio prior to ECMO initiation, the utilization of the prone positioning during ECMO, and the occurrence of pressure injuries. CONCLUSIONS: The incidence of pressure injuries was elevated in patients with Adult Respiratory Distress Syndrome who received ECMO. The development of pressure injuries was found to be independently associated with hypoxemia before ECMO initiation and the utilization of prone positioning during ECMO. IMPLICATIONS FOR CLINICAL PRACTICE: Patients who require ECMO for respiratory failure are at a high risk of developing pressure injuries. To ensure optimal outcomes during ECMO implementation and treatment, it is vital to implement preventive measures and to closely monitor skin health in at-risk areas.

Long term outcome in patients treated with veno-venous extracorporeal membrane oxygenation: A prospective observational study.

INTRODUCTION: Over the last few decades, the use of veno-venous extracorporeal membrane oxygenation (VV-ECMO) support for severe respiratory failure has increased. AIM: This study aimed to assess the long-term outcomes of patients treated with VV-ECMO for respiratory failure. METHODS: We performed a single-centre prospective evaluation of patients on VV-ECMO who were successfully discharged from the intensive care unit of an Italian University Hospital between January 2018 and May 2021. The enrolled patients underwent follow-up evaluations at 6 and 12 months after ICU discharge. The follow-up team performed psychological and functional assessments using the following instruments: Hospital Anxiety and Depression Scale (HADS), Post-traumatic Stress Disorder Symptom Severity Scale (PTSS-10), Euro Quality Five Domains Five Levels (EQ-5L-5D), and 6-minute walk test. RESULTS: We enrolled 33 patients who were evaluated at a follow-up clinic. The median patient age was 51 years (range: 45-58 years). The median duration of VV-ECMO support was 12 (9-19) days and the length of ICU stay was 23 (18-42) days. A HADS score higher than 14 was reported in 8 (24 %) and 7 (21 %) patients at the six- and twelve-month visit, respectively. PTSS-10 total score ≥ 35 points was present in three (9 %) and two (6 %) patients at the six- and twelve-month examination. The median EQ-5L-5D-VAS was respectively 80 (80-90) and 87.5 (70-95). The PTSS-10 score significantly decreased from six to 12 months in COVID-19 survivors (p = 0.024). CONCLUSIONS: In this cohort of patients treated with VV-ECMO, cognitive and psychological outcomes were good and comparable to those of patients with Adult Respiratory Distress Syndrome (ARDS) managed without ECMO. IMPLICATIONS FOR CLINICAL PRACTICE: The findings of this study confirm the need for long-term follow-up and rehabilitation programs for every ICU survivor after discharge. COVID-19 survivors treated with VV-ECMO had outcomes comparable to those reported in non-COVID patients.

Determinants of increased nursing workload in the COVID-era: A retrospective analysis of prospectively collected data.

BACKGROUND: COVID-19 is associated with increased nursing workload, therefore a high nurse-to-patient ratio would be required. AIM: To analyse difference in nursing workload, as expressed with the Nursing Activities Score (NAS), between COVID-19 patients versus control patients without COVID-19 disease (NCOVID-19 group) in an Italian Extracorporeal Membrane Oxygenation (ECMO) centre. STUDY DESIGN: Retrospective analysis of prospectively collected data, enrolling consecutive patients admitted to a general Intensive Care Unit, between 1st May 2019 and 28th February 2021. A multivariate analysis was then performed to assess if COVID-19 disease was an independent predictor of higher NAS and to assess which other factors and procedures are independently associated with increased workload. RESULTS: We enrolled 574 patients, of which 135 (24%) were in the COVID-19 group and 439 (76%) in the NCOVID-19 group. The average NAS was higher in the COVID-19 group (79 ± 11 vs. 65 ± 15, T = -10.026; p < 0.001). Prone positioning, continuous renal replacement therapy (CRRT) and ECMO were used more frequently in the COVID-19 group. A higher fraction of patients in the COVID group showed colonization from multidrug resistant bacteria. COVID-19 group had a higher duration of mechanical ventilation and longer ICU stay. The COVID-19 diagnosis was independently associated with a higher NAS. Other independent predictors of higher NAS were the use of prone positioning and continuous renal replacement therapy (CRRT). Colonization from multidrug resistant bacteria and ECMO support were not independently associated with higher NAS. CONCLUSIONS: The higher nursing workload in COVID-19 patients is mainly due to specific procedures required to treat the most hypoxemic patients, such as prone positioning. Colonization with multidrug resistant bacteria and ECMO support were not independently associated with a higher NAS. RELEVANCE TO CLINICAL PRACTICE: Higher workload in COVID-19 patients was due to specific interventions, such as prone positioning and CRRT, with the related nursing activities, as continuous presence at patient's bed, mobilization, positioning and complex hygienic procedures.

Patients' recollections of helmet-CPAP treatment during COVID-19 pandemic: A qualitative study.

BACKGROUND: During the pandemic outbreak, helmet continuous positive airway pressure (CPAP) was widely used as respiratory support for COVID-19 patients, inside and outside of intensive care units. The available literature suggests specific interventions to improve the comfort of patients treated with helmet-CPAP. Few reports are available on the experiences of patients undergoing this treatment. AIM: This qualitative study aimed to explore the views and recollections of COVID-19 patients undergoing helmet-CPAP. STUDY DESIGN: We conducted semi-structured interviews with thematic analysis. Participants were recruited from the follow-up programme for COVID-19 patients discharged from an Italian general intensive care unit. Participants were interviewed by telephone. Data analysis followed the principles of thematic synthesis approach. FINDINGS: We conducted 29 phone calls in patients eligible for the study. Five participants declared that they did not remember the time spent in hospital on helmet-CPAP. Twenty-four patients were then included. Two themes and six subthemes were generated from their interview data: (1) The helmet-CPAP as a life-saving treatment (subthemes: recognition of the usefulness of treatment and resilience); (2) the negative feelings related to helmet-CPAP application (subthemes: communication problems, entrapment, mental confusion, fear of dying). Each patient's experience was unique, but some discomfort elements such as noise, gas flow turbulence, choking sensation and thirst were found to be very common. CONCLUSIONS: The application of helmet-CPAP treatment generated positive and negative memories and feelings in COVID-19 patients during the pandemic. The patients' experience has provided an overview of the main factors of discomfort. This can be a starting point for taking corrective measures to promote greater helmet tolerance and subsequent treatment success. RELEVANCE TO CLINICAL PRACTICE: This study has provided an insight into the patient's recollections about helmet-CPAP treatment during a worldwide pandemic. The findings suggested strict applications of interventions aimed to reduce some issues that participants reported, to improve their compliance to treatment. Results from this study could help nurses in understanding the needs of patients treated with helmet-CPAP and may foster a care focused on patient-centred outcomes.

IgE response to Aed al 13 and Aed al 14 recombinant allergens from Aedes albopictus saliva in humans.

Background: Mosquito bite is normally associated with mild allergic responses, but severe localized or systemic reactions are also possible. Reliable tools for the diagnosis of mosquito allergy are still unavailable. Here, we investigated the IgE response to 3 potential salivary allergens identified in the saliva of the tiger mosquito Aedes albopictus. Methods: Serum from 55 adult individuals (28 controls and 27 allergic people), were analysed using an in-house Enzyme Linked ImmunoSorbent Assay (ELISA) against the Salivary Gland Extract (SGE) and the recombinant proteins albD7l2 (Aed al 2), albAntigen5-3 (Aed al 13) and albLIPS-2 (Aed al 14). Results: Fifteen of the 27 (56%) individuals having hypersensitive reactions to mosquito bites had IgE serum levels recognizing SGE. Negative sera did not show detectable levels of IgE targeting the SGE from the most common sympatric mosquito Culex pipiens. Among the positive individuals, 2 subjects displayed IgE targeting Aed al 2 (13%), while IgE recognizing Aed al 13 and Aed al 14 were detected in ten (67%) and seven (47%) individuals, respectively. Two sera from non-hypersensitive subjects had detectable levels of IgE targeting Aed al 13, suggesting possible cross-reaction with the homologue salivary proteins of multiple mosquito species or, more generally, of hematophagous insects. Conclusions: Our results indicate that Aed al 13 and Aed al 14 hold the potential to be developed as tools for the diagnosis of allergy to Ae. albopictus bites. Such tools would facilitate epidemiological studies on tiger mosquito allergy in humans and might foster the development of further protein-based assays to investigate cross-species allergies.

The role of intensive care unit diaries in the grieving process: A monocentric qualitative study.

BACKGROUND: The growing importance of psychological recovery for patients and their families following intensive care unit (ICU) experiences in recent years cannot be overemphasized. The ICU diary is used to aid patients in reducing the prevalence of post-traumatic stress disorder, anxiety, and depression. The usefulness of maintaining a diary during the grieving process has not yet been thoroughly investigated. AIM: To investigate the role of ICU diaries in the grief process experienced by family members of a person who died in the intensive care unit. STUDY DESIGN: Nine family members of seven deceased ICU patients with an ICU diary were contacted and interviewed by phone using a semi-structured interview. A qualitative data analysis was performed using thematic synthesis. SETTING: Italian general intensive care unit. FINDINGS: Interviewed family members felt that the diary helped them during the grieving process. The return of diaries was desired by family members for support and to remember one's loved one. The diary helped them process their losses in various ways, including signs of evidence of care, emotional involvement, consideration, and coping with grief. Four main themes emerged from the analysis: writing the diary, reading the diary, talking about the diary, and the diary during the grieving process. CONCLUSIONS: The overall perception of the ICU diary was positive. The diary mostly helped relatives to "give back something of what we lost". This study also affirms the positive link between ICU diaries and bereavement in Italian ICU. Further studies are required to confirm the usefulness of this tool in the grieving process. RELEVANCE TO CLINICAL PRACTICE: The ICU diary can help patients' family members understand what happened to their loved one and play an important role in the grieving process. The diary served as a valuable source of information that aided in providing bereavement support to the family by helping them to gain a rational and emotional understanding of the patient's death.

Long-Term Physical, Cognitive, and Psychological Outcomes in Severe COVID-19 Patients Managed With Extracorporeal Membrane Oxygenation: A Prospective Study.

Extracorporeal membrane oxygenation (ECMO) has been used in highly selected COVID-19 patients with severe respiratory failure. Scarce data exist on long-term outcomes of these patients. We performed a single-center prospective evaluation of consecutive COVID-19 ECMO patients successfully discharged from the intensive care unit between February 2020 and January 2022. Physical, cognitive and psychological outcome was assessed at 3, 6, and 12 months by in-person evaluation. All the 34 discharged patients (median age 49 years old) were alive at one year, and 25 of them were evaluated at the follow-up clinic. 67% of patients had muscle weakness, with improvement over time (p = 0.032). The percentage of patients able to return to work progressively increased, up to 86% at 1 year. 23% of patients experienced fatigue. Participation restriction improved over time for both physical (p = 0.050) and emotional (p = 0.005) problems. Cognitive impairment, anxiety, and depression occurred in 29%, 29%, and 23% of patients, respectively, with no changes over time. Health-related quality of life was good. In conclusion, COVID-19 ECMO patients suffer from significant long-term sequelae. However, multidimensional outcomes continued to improve over the follow-up time.

Hospital Memories and Six-Month Psychological Outcome: A Prospective Study in Critical Ill Patients with COVID-19 Respiratory Failure.

ICU survivors suffer from various long-term physical and psychological impairments. Memories from the critical illness may influence long-term psychological outcome. In particular, the role of ICU memories in COVID-19 critically ill patients is unknown. In a prospective observational study, we aimed to investigate patients' memories from the experience of critical illness and their association with a six-month psychological outcome involving quality of life evaluation. Patients' memories were investigated with ICU Memory tool, while psychological outcome and quality of life were evaluated by means of a battery of validated questionnaires during an in-person interview at the follow-up clinic. 149 adult patients were enrolled. 60% retained memories from pre-ICU days spent on a general ward, while 70% reported memories from the in-ICU period. Delusional memories (i.e., memories of facts that never happened) were reported by 69% of patients. According to a multivariable analysis, the lack of pre-ICU memories was an independent predictor of worse psychological outcomes in terms of anxiety, depression and Post-traumatic Stress Disorder (PTDS). Factors associated with long-term outcome in ICU survivors are not still fully understood and patients' experience during the day spent before ICU admission may be associated with psychological sequelae.

One hundred ECMO retrivals before and during the Covid-19 pandemic: an observational study.

OBJECTIVES: Patients with severe acute respiratory distress syndrome may require veno-venous extracorporeal membrane oxygenation (V-V ECMO) support. For patients in peripheral hospitals, retrieval by mobile ECMO teams and transport to high-volume centers is associated with improved outcomes, including the recent COVID-19 pandemic. To enable a safe transport of patients, a specialised ECMO-retrieval program needs to be implemented. However, there is insufficient evidence on how to safely and efficiently perform ECMO retrievals. We report single-centre data from out-of-centre initiations of VV-ECMO before and during the COVID-19 pandemic. DESIGN & SETTING: Single-centre retrospective study. We include all the retrievals performed by our ECMO centre between January 1st, 2014, and April 30th, 2021. RESULTS: One hundred ECMO missions were performed in the study period, for a median retrieval volume of 13 (IQR: 9-16) missions per year. the cause of the acute respiratory distress syndrome was COVID-19 in 10 patients (10 %). 98 (98 %) patients were retrieved and transported to our ECMO centre. To allow safe transport, 91 of them were cannulated on-site and transported on V-V ECMO. The remaining seven patients were centralised without ECMO, but they were all connected to V-V ECMO in the first 24 hours. No complications occurred during patient transport. The median duration of the ECMO mission was 7 hours (IQR: 6-9, range: 2 - 17). Median duration of ECMO support was 14 days (IQR: 9-24), whereas the ICU stay was 24 days (IQR:18-44). Overall, 73 patients were alive at hospital discharge (74 %). Survival rate was similar in non-COVID-19 and COVID-19 group (73 % vs 80 %, p = 0.549). CONCLUSION: In this single-centre experience, before and during COVID-19 era, retrieval and ground transportation of ECMO patients was feasible and was not associated with complications. Key factors of an ECMO retrieval program include a careful selection of the transport ambulance, training of a dedicated ECMO mobile team and preparation of specific checklists and standard operating procedures.

Short and long-term complications due to standard and extended prone position cycles in CoViD-19 patients.

OBJECTIVE: To investigate short and long-term complications due to standard (≤24 hours) and extended (>24 hours) prone position in COVID-19 patients. METHODS: Retrospective cohort study conducted in an Italian general intensive care unit. We enrolled patients on invasive mechanical ventilation and treated with prone positioning. We recorded short term complications from the data chart and long-term complications from the scheduled follow-up visit, three months after intensive care discharge. RESULTS: A total of 96 patients were included in the study. Median time for each prone positioning cycle (302 cycles) was equal to 18 (16-32) hours. In 37 (38%) patients at least one cycle of extended pronation was implemented. Patients with at least one pressure sore due to prone position were 38 (40%). Patients with pressure sores showed a statistically significative difference in intensive care length of stay, mechanical ventilation days, numbers of prone position cycles, total time spent in prone position and the use of extended prone position, compared to patients without pressure sores. All lesions were low grade. Cheekbones (18%) and chin (10%) were the most affected sites. Follow-up visit, scheduled three months after intensive care discharge, was possible in 58 patients. All patients were able to have all 12 muscle groups examined using theMedical Research Council scale examination. No patient reported sensory loss or presence of neuropathic pain for upper limbs. CONCLUSIONS: Extended prone position is feasible and might reduce the workload on healthcare workers without significant increase of major prone position related complications.

Implementation of a Follow-Up Program for Intensive Care Unit Survivors.

In Intensive Care Unit (ICU) survivors, critical illness has an impact on an individual's long-term health status and quality of life. Adults who have recovered from intensive care management could develop muscle weakness, neurocognitive impairment, difficulties in managing activities of daily living and to returning to work, and psychological problems such as depression and anxiety. A prospective, observational study was designed. Data were collected from January to December 2018 from a structured follow-up program, at 3 time points after ICU discharge: at seven days, a visit in the general ward, a phone interview at three months and an ambulatory visit at six months. A total of 95 patients were enrolled, 36% female, with a median age of 65 (55-73) years and a median ICU length of stay of 13 (8-20) days. At the seven days follow-up, patients who had a positive Hospital Anxiety and Depression Scale showed a significantly longer time of intubation (p = 0.048) and length of ICU stay (p = 0.023). At three months, we observed a significant relationship between a positive Hospital Anxiety and Depression Scale and a median value of EuroQol-5D (p = 0.048). At six months, we observed that patients who had a positive Post-Traumatic Symptom Scale were significantly younger than the other group. Findings from the present study suggest that a longer time of intubation and length of ICU stay are associated with a higher level of anxiety and depression immediately after ICU discharge. Follow-up programs are recommended to assess and rehabilitate cognitive function at ICU discharge.

Use of Intensive Care Unit Diary as an Integrated Tool in an Italian General Intensive Care Unit: A Mixed-Methods Pilot Study.

PURPOSE: The aim of this study was to investigate the implementation of an intensive care unit (ICU) diary in an Italian general ICU. METHODS: A mixed-methods pilot study was performed, enrolling all patients who received an ICU diary in an Italian ICU during the study period. RESULTS: Study results are presented in 2 sections: (1) diary evaluation and content themes and (2) follow-up program results. Sixty-six patients were assessed for eligibility. Diary administration was possible in 31 patients (47%). The overall diary entries, in 31 analyzed diaries, were 1331, with a median of 25 entries (interquartile range, 16-57 entries) for each diary. Participants' relatives and friends wrote a median of 1.2 (0.3-1.6), and nurses wrote 1.1 (0.8-1.2). Other ICU staff wrote a total of 24 entries (2%). Follow-up results revealed low incidence of delirium detected in only 1 patient at the 7-day visit (3%). The median value of PTSS-10 (Post Traumatic Stress Symptoms) score was 12 (3.5-12) at the 7-day visit, 6 (1.5-12) at 3 months' telephone interview, and 12 (1.5-17) at 6 months' visit. CONCLUSIONS: To our knowledge, this is the first Italian report about the introduction of an ICU diary. The diaries were easily implemented in our clinical practice as a "low-cost" initiative. In our study, nurses and participants' relatives and friends wrote a similar number of entries in each analyzed diary. This project could be effective in reducing survivors' delirium and post-traumatic stress disorder and in implementing mutual understanding between clinical staff and relatives during ICU stay.

Hemophagocytic Lymphohistiocytosis: A Dangerous Intruder in Pediatric Acute Lymphoblastic Leukemia.

Hemophagocytic lymphohistiocytosis (HLH) is a condition caused by a pathologic immune activation, which is responsible for its signs and symptoms. It may also appear as a secondary process caused by malignancy. Developing HLH during treatment for acute lymphoblastic leukemia (ALL) is extremely uncommon, but underdiagnosis may be fatal. Two patients with ALL on chemotherapy maintenance treatment who developed HLH triggered by infection are presented here. We emphasize the importance of being aware of this condition when a patient with ALL in complete remission presents with unexplained hepatomegaly, cytopenia, and fever. Early diagnosis and treatment may be lifesaving.

Analysis of the Efficacy and Safety of Increasing the Energy Dose Applied Per Session by Increasing the Number of Shock Waves in Extracorporeal Lithotripsy: A Prospective and Comparative Study.

PURPOSE: To evaluate the efficacy and safety of increasing the energy dose in treating urinary lithiasis with extracorporeal lithotripsy through an expanded number of Shock Waves Per Session (SWPS). MATERIALS AND METHODS: a randomized, prospective, and comparative study was performed with patients with renal or ureteral lithiasis from 2011 to 2014. Two groups were studied: Group A (n = 136), treated with 3500 SWPS, and Group B (n = 171), subjected to an expanded treatment with 7000 SWPS. Patients were considered stone free when there was no lithiasis or it were less or equal to 4 mm after treatment. Variables related to the patient, stones, treatment, and complications were collected. RESULTS: The global SFR was 75.0% and 87.7% in Groups A and B, respectively (p = 0.004). In renal location, the SFR was higher in Group B (74.1% vs 90.7%, p = 0.003) regardless of the size. In the ureteral location, there were differences in the pelvic only (73.7% vs 95.2%). There were no differences in either the complication rate (27.2% vs 25.7%, p = 0.77), or the severity between the two groups. The variable "number of SWPS" was seen to be an independent predictor of the resolution of lithiasis, having the probability of resolving lithiasis 2.62 (CI 95% = 1.40-4.89) times greater when applying 7000 SWPS. CONCLUSION: In our study, increasing the energy dose applied through an expanded number of SWPS has been shown to be more effective than standard regimens with a similar safety profile. However, more clinical studies on different types of lithotripters are required to confirm these results.

[New strategies and protocols in SWL.] / Nuevas estrategias y protocolos en LEOC.

OBJECTIVE: An update of the new treatment strategies in extracorporeal lithotripsy as a valid therapeutic alternative in the management of urinary calculi. METHODS: We performed a search and review of the most recent literature which responded to the terms "best practices", "update", "optimization", "practice pattern" in lithotripsy. Only articles written in English or Spanish were selected. RESULTS: The use of a stepwise voltage ramping during extracorporeal lithotripsy with or without pause before the first rise of energy, a decreased delivery rates and the use of a higher number of shock waves per session are shown as alternatives to improve the effectiveness with optimum safety profile. CONCLUSIONS: Extracorporeal lithotripsy is still an effective and minimally invasive treatment, and it has an important role in the treatment of urolithiasis. New treatment strategies are being developed to increase the effectiveness with a similar safety profile.

Nuestro objetivo en este trabajo es describir dicho impacto y recoger aquellas medidas que pueden paliar los síntomas relacionados con su uso. MÉTODOS: Se ha realizado una búsqueda de artículos en las fuentes bibliográficas Cochrane library, Uptodate, Pubmed, Tripdatabase, seleccionando publicaciones entre 2000-2015 y las guías europeas EAU 2016. Se seleccionaron aquellos estudios que evaluaron la calidad de vida con catéteres doble J y las posibles soluciones. RESULTADOS: Se incluyeron 6 estudios cualitativos sobre calidad de vida, 6 ensayos clínicos sobre nuevos diseños en catéteres doble J, y 3 revisiones sistemáticas. La mayoría de los estudios utilizaron el cuestionario USSQ de calidad de vida. Se describen los principales problemas, siendo los mas frecuentes e importantes los síntomas de llenado y dolor. Entre las posibles soluciones se encuentran modificaciones en diseño y composición del catéter y sobre todo el uso de alfa-bloqueantes y anticolinérgicos para mejorar la CdV. CONCLUSIÓN: Los catéteres doble J presentan una importante repercusión sintomática y deterioro en la CdV lo cual hace necesario una indicación adecuada, limitar su duración y utilizar todas aquellas medidas tecnológicas y farmacológicas para paliar sus efectos

OBJECTIVE: Double J ureteral stents are frequently used to allow free diuresis from the kidney to the bladder, but their presence has a major impact on patient`s quality of life (QoL). Our aim is to describe such impact, and to describe possible solutions that can alleviate the symptoms associated with their use. METHODS: Systematic search in bibliographic sources including Cochrane library, UpToDate, Pubmed, Tripdatabase, selecting publications between 2000-2015, and also the EAU European guidelines (2016). Studies that assessed QoL with double J stents and possible solutions were selected. RESULTS: We included 6 qualitative studies on QoL, 6 clinical trials of double J catheters new designs, and 3 systematic reviews. Most studies used the USSQ (QoL) questionnaire and main problems are described, being storage symptoms and pain the most frequent and important. Possible solutions include modifications in design and composition of the catheter and specially, the use of alpha-blockers and anticholinergics to improve QoL. CONCLUSION: Double J stents have an important symptomatic impact that impairs QoL. They should be used under appropriate indication; their duration should be limited and we must employ all the technological and pharmacological approaches to mitigate their effects

High-dose busulfan and cyclophosphamide as a conditioning regimen for autologous peripheral blood stem cell transplantation in childhood non-Hodgkin lymphoma patients: a long-term follow-up study.

We analyzed the outcome in 22 children with refractory or relapsed non-Hodgkin lymphoma who underwent autologous peripheral blood progenitor cell transplantation between 1994 and 2009. The conditioning regimen used in all patients consisted of busulfan and cyclophosphamide. Median age was 6 years (range 2 to 16 y). The most common histologic subtype was Burkitt lymphoma. Ten patients were in complete remission and 12 in partial remission at the time of transplant. The median dose of CD34+ cells that was infused was 4.6 × 10/kg (range 2.1 to 58.7 × 10/kg). All the patients were engrafted, with a median time for neutrophils and platelets recovery of 11 (range, 8 to 15 d) and 14 (range, 9 to 60 d) days, respectively. Nonhematologic treatment-related toxicity included severe mucositis in 3 patients and hepatic sinusoidal obstruction syndrome in 1 patient. There were no transplant-related mortalities. With a median follow-up of 60 months (range, 4 to 180 d) the disease-free survival was 90 ± 6.5% for the whole group. This retrospective study shows a high long-term survival using busulfan/cyclophosphamide as conditioning regimen in children with refractory or relapsed non-Hodgkin lymphoma.

High-dose busulfan and melphalan as conditioning regimen for autologous peripheral blood progenitor cell transplantation in high-risk neuroblastoma patients.

The aim of this retrospective study was to analyze the outcome and identify risk factors associated with progression-free survival (PFS) in 36 children with high-risk neuroblastoma who underwent autologous peripheral blood progenitor cell (PBPC) transplantation between 1994 and 2010. The conditioning regimen used in all cases consisted of high-dose of busulfan and melphalan. Median age at transplantation was 3 years (range: 0.7-14 years). The median times to neutrophil and platelet engraftment were 11 days (range: 9.16 days) and 13 days (range: 9.33), respectively. Twenty-one patients developed nonhematologic toxicity: 15 patients had mucositis, 4 patients developed an engraftment syndrome, and there were 2 cases of liver toxicity. No toxic deaths were observed. There were 15 patients who relapsed. The median time to relapse was 6 months after the transplant (range: 3-13 months). With a median follow-up of 55 months (range: 4-180 months), the PFS was 57% ± 8.5% for the whole group. In multivariate analysis, age below 3 years (P < .005), complete remission (CR) pretransplantation (P < .07) and 1p germline status (P < .01) were variables associated with better outcomes. Patients who were or achieved early CR following transplantation (3 months posttransplantation) had a probability of PFS of 91% ± 6% as compared to patients who did not (PFS 9% ± 8%) (P < .0001). This retrospective study shows that high dose of busulfan and melphalan as conditioning regimen in children with high-risk neuroblastoma is associated with very low morbidity and no mortality in the authors' hands. Younger patients with no 1p deletions and in first CR at transplantation had the better outcome.

[Comparative study between analgesic efficacy and safety of meperidine compared with lidocaine periprostatic infiltration in transrectal ultrasound guided prostate biopsy]. / Estudio comparativo entre la eficacia analgésica y seguridad de la meperidina intravenosa frente a la infiltración periprostática con lidocaína en biopsias transrectales de próstata.

OBJECTIVES: To assess the efficacy of intravenous analgesia with meperidine compared to periprostatic plexus infiltration with lidocaine, and safety of periprostatic local anesthesia. MATERIALS AND METHODS: A prospective randomized study with 100 patients undergoing first or second prostate biopsy. We distribute patients in two groups, group A (50 patients) which was administered 50 mg of intravenous meperidine and group B (50 patients) receiving 5 mL of lidocaine 2% in the angle between prostate and seminal vesicles. Pain was assessed by Visual Analog Scale (VAS) and a questionnaire about the emotional impact. Procedure safety was obtained by telephone questionnaire about prostate biopsy complications. The statistical analysis used was chi square test, Student's t test and Kruskal-Wallis no parametric test. RESULTS: Median age was 66 years (47-80) and both groups were homogeneous with regard to: PSA, prostate volume, core's number and educational level without significant differences. 74 patients (74%) had their first biopsy and 26 (26%) had their second one. The average number of core biopsy was 10,9 +/- 2, and VAS mean score for group A was 3,6 +/- 1,8 versus 3,2 +/- 2 Group B without significant differences (p>0,05). We found significant differences (p<0,05) between transducer introduction (3,9 +/- 1,9 group A/B group 4,3 +/- 2,2) and core biopsy (3,6 +/- 1,8 group A/B group 3,2 +/- 2,2). There were no differences between the data obtained with emotional impact test, age and educational level comparing to pain caused by prostate biopsy. Regard to the number of cores obtained there were no differences (p>0,05). Complications appeared in 12 patients (12%), 5 in the group of meperidine compared with 7 in the lidocaine without differences between them. CONCLUSION: Periprostatic plexus blocked with lidocaine does not offer advantages respect to meperidine, despite the fact that this is a safe method that does not increase the number of complications. Placing transrectal transducer causes more pain than biopsy cores.
