Association of the superior semicircular canal and tegmen tympani dehiscences and its relationship with the pneumatisation of the temporal bone.

PURPOSE: To analyse the degree of pneumatisation of the temporal bone when there is an association between dehiscence of the superior semicircular canal and dehiscence of the tegmen tympani. MATERIALS AND METHODS: We analysed a retrospective CT study of 124 selected cases. A single inclusion criterion was applied: the presence of a dehiscence of the tegmen tympani. On the other hand, the degree of temporal pneumatisation was assessed by axial and coronal planes, and has been divided into the following grades O, I, II and III, according to the status and relationship of the mastoid, the bony labyrinth, the petrous segment of the carotid canal and sigmoid sinus. RESULTS: Of the 124 cases studied, 35 (28.2%) presented both dehiscences. In 26 of the 35 (47.3%), grade II pneumatisation, 4 (14,8%), grade I, and 5 (11,9%) grade III was observed, with a statistically significant relationship (p < 0.001). On the other hand, we did not find a significant relationship when relating both dehiscences in any age or sex group. However, when relating the degree of pneumatisation to sex, among those with grade III pneumatisation, the proportion of men (52.4%) was significantly higher than that of women (47.6%) (p = 0.017). CONCLUSION: We have detected a statistically significant relationship between the coexistence of grade II pneumatisation and the presence of both dehiscences in the temporal bone.

Crop year, harvest date and clone effects on fruit characteristics, chemical composition and olive oil stability from an Empeltre clonal selection grown in Aragon.

BACKGROUND: In this study, the effects of crop year, harvest date and clone on the fruit characteristics and chemical composition of Empeltre olive oils were evaluated. For this purpose, the weight and oil content of fruit and the fatty acid composition, polyphenol content and oxidative stability of the olive oil was analysed throughout ripening during three successive seasons. RESULTS: The weight and moisture in the fruit, as well as the fatty acids and polyphenol content in the olive oil, were mainly affected by crop year. In contrast, the stability was strongly influenced by the harvest date. Both factors had an influence on the fruit's oil content. The clone was not a substantial component in terms of variability, although the interaction with crop year was notable for some of the characteristics. The oil content increased significantly along with the harvest date and reached maximum values in the last period (44.9%). Conversely, stability and polyphenols decreased significantly (depending on the year, by 30-70%) from October to December, reaching the highest mean values between 1 October and 10 November (15.5 h; 500 mg caffeic acid kg-1 ). Oleic acid and monounsaturated/polyunsaturated fatty acids (MUFA/PUFA) did not show significant differences depending on the harvest date, but between years, with 2018 having the highest percentage of oleic acid (72.72%) and MUFA/PUFA (8.38). CONCLUSION: Early harvesting of Empeltre olives would provide considerably more stable olive oils, regardless of the clone selected, with higher phenolic content. It would not affect the MUFA/PUFA ratio, mainly influenced by the crop year. © 2022 The Authors.

[How to organize a Fetal Medicine Unit in the context of COVID-19 pandemic. Safe measures for obstetric scans and equipment cleaning]. / Cómo reestructurar una Sección de Medicina Fetal en tiempos de pandemia COVID-19. Medidas de seguridad y limpieza de los equipos ecográficos.

During a pandemic, the three basic principles are. to prioritize medical resources, ensure patients' lockdown in order to avoid community transmission and prevent healthcare collapse, and keep the number of visits to an absolute minimum to avoid patient exposure and safeguard healthcare workers. Antenatal care must be maintained during a health crisis, regardless of the COVID-19 state of alert. Routine and specialist obstetric ultrasound scans are essential for clinical decision-making during pregnancy, as it has a direct impact on the management of mothers and fetuses and on the perinatal outcome. In an attempt to minimize in-person visits, these will be organized according to the established ultrasound schedule. Based on scientific evidence, and on existing main national and international guidelines, this document has been prepared, in which proposals and options are provided for managing pregnant women in the context of the SARS-CoV-2 pandemic. It includes how a Fetal Medicine Unit facing this health crisis should be restructured, what safety measures should be followed in the performance of obstetric scans and invasive procedures, and how ultrasound rooms, equipment and transducers should be cleaned and disinfected. These recommendations should be adapted to different units based on their resources and infrastructure.

From laboratory to the field: biological control of Fusarium graminearum on infected maize crop residues.

AIM: To evaluate biological control agents (BCAs) against Fusarium graminearum on infected maize stalks as a means to reduce Fusarium head blight (FHB) in subsequently grown wheat. METHODS AND RESULTS: In the laboratory, BCAs were applied against F. graminearum on maize stalk pieces. Clonostachys rosea inhibited the perithecia development and ascospore discharge when applied before, simultaneously with and after the pathogen. In the field, we simulated a system with high disease pressure, that is, a maize-wheat rotation under no-tillage, by preparing maize stalks inoculated with F. graminearum. The infected stalks were treated with formulations of C. rosea selected in vitro or the commercial BCA strain Trichoderma atrobrunneum ITEM908 and exposed to field conditions over winter and spring between winter wheat rows. Monitoring with spore traps and of FHB symptoms, as well as quantification of F. graminearum incidence and DNA in harvested grain revealed significant reductions by C. rosea by up to 85, 91, 69 and 95% compared with an inoculated but untreated positive control, respectively. Deoxynivalenol (DON) and zearalenone (ZEN) contents were reduced by up to 93 and 98%, respectively. Treatments with T. atrobrunneum were inconsistent, with significant reductions of DON and ZEN under warm and wet climatic conditions only. CONCLUSIONS: The findings support the application of C. rosea against F. graminearum on residues of maize to suppress the primary inoculum of FHB. SIGNIFICANCE AND IMPACT OF THE STUDY: As sustainable agriculture requires solutions to control FHB, hence, the application of C. rosea during the mulching of maize crop residues should be evaluated in on-farm experiments.

Point-of-care lung ultrasound in three neonates with COVID-19.

Since March 2020, the world is involved in the COVID-19 pandemic, a disease caused by a novel virus called SARS-CoV-2. Some authors have described the ultrasonographic findings of COVID-19 pneumonia in adults and children, but data on neonates are lacking. Our objective was to describe the ultrasonographic lung pattern on newborns with SARS-CoV-2 infection during the COVID-19 pandemic. Newborns who tested positive for SARS-CoV-2 PCR in respiratory samples and were evaluated with point-of-care lung ultrasound (LU) from March to April 2020 were included. LU was performed bedside by a single investigator at the time of diagnosis and every 48 h during the first week following diagnosis. Six areas were studied. Three neonates were included. Infants' comorbidities included meconium aspiration syndrome, bronchopulmonary dysplasia, and Hirschsprung's disease. One required mechanical ventilation. No deaths occurred. LU showed B-lines, consolidation, and spared areas. No pneumothorax or pleural effusion was observedConclusions: LU could be of value when managing COVID-19 neonates. We describe the findings of lung ultrasound monitoring during the first week following diagnosis in three neonates with SARS-CoV-2 infection. What is known: • Lung ultrasound (LU) is a useful tool in COVID-19 management in adults. To date, no report on LU and neonates with SARS-CoV-2 infection has been published. What is new: • This study adds evidence about LU findings in neonates with SARS-CoV-2 infection.

Thrombotic Event Prevention in Patients Undergoing Posterior Lumbar Arthrodesis: our experiencie. A retrospective case series study. / Prevención de eventos trombóticos en pacientes sometidos a cirugía de artrodesis lumbar por vía posterior: experiencia en nuestro centro. Estudio retrospectivo de casos.

INTRODUCTION: There is no generalized consensus regarding perioperative prophylaxis of venous thromboembolism (VTE), either on using or timing it in patients undergoing spine surgery. VTE is a current concern because, even though being an uncommon event, it can cause serious complications. The aim of the present study is to propose guidelines for the prevention of thrombotic events in posterior spinal surgery, either as deep vein thrombosis or pulmonary thromboembolism. If the number of patients getting prophylaxis drugs is reduced a subsequent reduction of the incidence of epidural hematoma can be expected. MATERIALS AND METHODS: A number of 235 patients who had undergone posterior spinal arthrodesis in the previous five years were studied. Mechanical thromboprophylaxis measures consisting of compression stockings were applied in all of them. Anticoagulant drugs were also applied whenever risk factors for thrombosis were observed. Early weight-bearing was resumed immediately after surgery. Demographic, clinical, and surgical variables were collected, as well as complications appearing during the follow-up period, that was scheduled at one, two, four, six and twelve months after the surgery. Thrombotic events, if present, were diagnosed by clinical and imaging tests such as ultrasound and CT angiography. RESULTS: From the total 235 patients of this series, one hundred and fifty-three cases met the study inclusion criteria. A total of four thrombotic events appeared, one in the form of deep vein thrombosis and other three in the form of pulmonary thromboembolism. These last patients suffering an embolism died because of it. None of the variables studied had statistical significance for the occurrence of a thrombotic event. All four patients who suffered thrombotic events were receiving anticoagulant drugs, in addition to mechanical compression stockings, because of the presence of risk factors for thrombosis. CONCLUSIONS: By applying the fore mentioned protocol, adequate prevention of thromboembolic events was achieved in this study population of patients undergoing posterior spinal surgery.

Neurophobia among resident physicians in the emergency service. / Neurofobia entre médicos residentes en los servicios de urgencias.

INTRODUCTION: Neurophobia is defined as the fear towards clinical neurology caused by the inability to apply theoretical knowledge to practical clinical situations. This phenomenon is not restricted to medical students and has never been studied before in the Emergency Department. We aimed to study how resident doctors perceive their knowledge in neurology and urgent neurological conditions as well as possible causes for said fears. MATERIALS AND METHODS: Cross-sectional multicentric study using self-administered surveys sent to medical residents within the Aragon Health Service. They were questioned about their fear of neurology and other medical specialties, possible causes, and perception of knowledge in neurological pathologies and subareas in the emergency service. RESULTS: We obtained 134 responses. 27.6% (37) suffered from neurophobia. Despite neurology being considered the most difficult discipline, it did also arouse the third most interest among the students. The areas where they showed the most confidence were headaches and vascular pathology. The areas where they felt the most insecure were neuromuscular diseases, neuro-ophthalmology, and spinal cord injury. In none of the areas surveyed, the percentage of respondents who felt secure exceeded 50%. CONCLUSIONS: Neurophobia is prevalent among trainee doctors working in the emergency department. Their confidence correlates with the degree of exposure to patients. Neurologist must play an active role in the education of new specialist and promote the collaboration with emergency departments.

TITLE: Neurofobia entre médicos residentes en los servicios de urgencias.Introducción. La neurofobia se define como el miedo hacia la neurología que surge de la incapacidad para aplicar los conocimientos teóricos a situaciones clínicas prácticas. Este fenómeno parece no limitarse únicamente a estudiantes de medicina, pero no se dispone de estudios previos en el ámbito de urgencias. Este trabajo valora la percepción de conocimientos en las distintas patologías neurológicas urgentes por parte de médicos en formación y posibles motivos de neurofobia. Material y métodos. Se trata de un estudio transversal multicéntrico mediante encuestas autoadministradas a médicos en formación de todo el Servicio Aragonés de Salud. Se interrogó sobre su miedo a la neurología y otras especialidades médicas, posibles causas y percepción de conocimientos en patologías neurológicas en el servicio de urgencias. Resultados. Se obtuvieron 134 respuestas. El 27,6% (37) sufría neurofobia. La neurología fue la tercera disciplina que mayor interés despertó, pero se considera la de mayor dificultad. Las áreas en las que mayor seguridad mostraron fueron las cefaleas y la patología vascular. Donde mayor inseguridad existía fue en la neuromuscular, la neurooftalmología y la lesión medular aguda. En ninguna de las áreas hubo un porcentaje mayor del 50% que se sintiera seguro o muy seguro. Conclusiones. La neurofobia está presente entre los médicos en formación que desempeñan su labor en los servicios de urgencias. Su distribución depende del grado de exposición a los pacientes. Los neurólogos debemos desempeñar un papel activo en la formación de nuevos especialistas y promover la colaboración con los servicios de urgencias.

100 Years since Robert Barany's visit to the Zaragoza medical faculty.

In December 1923, a twelve-day course took place at the University of Zaragoza, specifically at the Faculty of Medicine, given by Professor Róbert Bárány, who was awarded the Nobel Prize for Medicine in 1914 for his discoveries on the vestibular apparatus.Professor Robert Bárány came to the faculty at the invitation of Professor Victor Fairén through the University Exchange programme. This course consisted of four lectures and twelve lessons a day in which he presented his knowledge of the physiopathology of the vestibule and cerebellum, as well as practical demonstrations of the physical examination of nystagmus and cerebellar pathology.Lorente de Nó, a doctorate student of medicine, was one of the most outstanding students on the course. His intellect was already outstanding in those years, which helped him to discuss the physiopathology of nystagmus with Professor Bárány. The relationship he forged with the Nobel laureate in Zaragoza would be decisive for his future as a researcher.The aim of this work is to compile and integrate the available information on the course that Professor Bárány took in the city of Zaragoza, consulting official documents from the university and the city, articles, books and the press of the time.

Neurophobia among undergraduate medical students: a European experience beyond the Anglosphere. / Neurofobia entre los estudiantes de medicina de una universidad española: experiencias más allá de la anglosfera.

INTRODUCTION: Neurophobia is defined as the fear of the neural sciences and clinical neurology that is due to the students' inability to apply their knowledge of basic sciences to clinical situations. This phenomenon, well documented in the Anglosphere, has seldom been studied in other European countries and never in our country. Our study aimed to determine whether said fear existed among Spanish medical students. MATERIAL AND METHODS: A self-administered questionnaire with 18 items was sent to medical students in the second, fourth and sixth years of medical school at a Spanish university during the academic years 2020-2021 and 2021-2022. They were questioned about their fears regarding neurology and neurosciences, causes and potential solutions. RESULTS: Out of 320 responses, 34.1% suffered from neurophobia and only 31.2% felt confident they knew what neurologists do. Despite Neurology being considered the most difficult discipline, it did also arouse the most interest among the students. Main reasons identified for neurophobia were too theoretical lectures (59.4%), neuroanatomy (47.8%), and a lack of integration between neuroscience subjects (39.5%). Solutions considered most important by the students to reverse this situation went along those lines. CONCLUSION: Neurophobia is prevalent among Spanish medical students too. Having identified the teaching methodology as one of its fundamental causes, neurologists have the opportunity and obligation to reverse this situation. We should strive for more proactive involvement of neurologists at earlier stages of medical education.

Impact of Sepsis Flow Chip, a novelty fast microbiology method, in the treatment of bacteremia caused by Gram-negative bacilli.

OBJECTIVE: The aim of this study was to assess the impact of the information provided by the new Sepsis Chip Flow system (SFC) and other fast microbiological techniques on the selection of the appropriate antimicrobial treatment by the clinical researchers of an antimicrobial stewardship team. METHODS: Two experienced clinical researchers performed the theoretical exercise of independently selecting the treatment for patients diagnosed by bacteremia due to bacilli gram negative (BGN). At first, the clinicians had only available the clinical characteristics of 74 real patients. Sequentially, information regarding the Gram stain, MALDI-TOF, and SFC from Vitro were provided. Initially, the researchers prescribed an antimicrobial therapy based on the clinical data, later these data were complementing with information from microbiological techniques, and the clinicians made their decisions again. RESULTS: The data provided by the Gram stain reduced the number of patients prescribed with combined treatments (for clinician 1, from 23 to 7, and for clinician 2, from 28 to 12), but the use of carbapenems remained constant. In line with this, the data obtained by the MALDI-TOF also decreased the combined treatment, and the use of carbapenems remained unchanged. By contrast, the data on antimicrobial resistance provided by the SFC reduced the carbapenems treatment. CONCLUSIONS: From the theoretical model the Gram stain and the MALDI-TOF results achieved a reduction in the combined treatment. However, the new system tested (SFC), due to the resistance mechanism data provided, not only reduced the combined treatment, it also decreased the prescription of the carbapenems.

Diet and prevalence of atopic eczema in 6 to 7-year-old schoolchildren in Spain: ISAAC phase III.

BACKGROUND: The prevalence of atopic dermatitis (AD), a chronic skin disease, has increased substantially in recent decades, and different factors have been implicated in its etiology. Although dietary habits are being investigated, few conclusive findings have been reported. Nevertheless, increased consumption of polyunsaturated fatty acids (PUFA) and a diet poor in antioxidants have been related to AD. OBJECTIVES: The objectives of this study were to investigate the association between AD, the intake of different foods, and the effect of a Mediterranean diet among Spanish schoolchildren aged 6 to 7. METHODS: We performed a cross-sectional study with 20 106 schoolchildren aged 6-7 years from 10 different areas of Spain. The participation rate was 76.50%. The prevalence of AD was assessed using the International Study of Asthma and Allergies in Childhood questionnaire and the criteria of the Spanish Academy of Dermatology. To calculate the Mediterranean diet score, we classified food into 2 groups: Mediterranean food, including fruit, seafood, vegetables, pulses, cereals, pasta, rice, and potatoes; and non-Mediterranean food, including meat, milk, and fast food. RESULTS: Milk was negatively associated with AD. Butter and nuts also were negatively associated, although statistical significance was only reached when these foods were consumed 3 or more times a week. CONCLUSIONS: We found no association between the Mediterranean diet score and AD and a positive association between AD and obesity.

Characterization of the olive oil from three potentially interesting varieties from Aragon (Spain).

The commercial potential of olive oils from three autochthonous olive varieties Bodocal, Racimilla and Negral from Aragón (Spain) has been examined. Physicochemical characteristics, sensory analysis, nutritional composition, color and pigments were considered. The three varieties are generally used for producing table olives or olive oil in coupages but not for the production of monovarietal virgin olive oil. The values of the physicochemical and sensory analysis for the three olive oils corresponded to extra virgin category, however important differences among the three oils were observed in relation to pigment content, color measurements and fatty acid and phenol and tocopherol composition. Several characteristics such as oil yield, fatty acid and phenol and tocopherol content and sensory profiles suggested that some of these oils are of a promising composition. The olive yield of the Bodocal variety was the lowest (17%) and its corresponding oil had the smallest oleic acid (69%), phenols (272 mg gallic acid/kg) and tocopherol (96 mg/kg) contents and not equilibrated sensory parameters. The main characteristics of the Racimilla variety were a very high oil yield (28%) with very high contents in oleic acid (79 %) and phenols (831 mg gallic acid/kg). The oil of the Negral variety had very equilibrated sensory properties and its oleic acid content (76%) was similar to that of Racimilla. Its phenol content (456 mg gallic acid/kg) was between that of the other two varieties and its tocopherol content (190 mg/kg) was the highest. Therefore, the two last varieties could be of great interest for producing monovarietal olive oils.

Etiology of bloodstream infections at a population level during 2013-2017 in the Autonomous Community of Valencia, Spain.

OBJECTIVE: Bloodstream Infections has become in one of the priorities for the antimicrobial stewardship teams due to their high mortality and morbidity rates. Usually, the first antibiotic treatment for this pathology must be empirical, without microbiology data about the microorganism involved. For this reason, the population studies about the etiology of bacteremia are a key factor to improve the selection of the empirical treatment, because they describe the main microorganisms associated to this pathology in each area, and this data could facilitate the selection of correct antibiotic therapy. METHODS: This study describes the etiology of bloodstream infections in the Southeast of Spain. The etiology of bacteremia was analysed by a retrospective review of all age-ranged patients from every public hospital in the Autonomous Community of Valencia (approximately 5,000,000 inhabitants) for five years. RESULTS: A total of 92,097 isolates were obtained, 44.5% of them were coagulase-negative staphylococci. Enterobacteriales was the most prevalent group and an increase in frequency was observed along the time. Streptococcus spp. were the second microorganisms more frequently isolated. Next, the most prevalent were Staphylococcus aureus and Enterococcus spp., both with a stable incidence along the study. Finally, Pseudomonas aeruginosa was the fifth microorganism more frequently solated. CONCLUSIONS: These data constitute a useful tool that can help in the choice of empirical treatment for bloodstream infections, since the knowledge of local epidemiology is key to prescribe a fast and appropriate antibiotic therapy, aspect capital to improve survival.

How well do questionnaires perform compared with physical examination in detecting flexural eczema? Findings from the International Study of Asthma and Allergies in Childhood (ISAAC) Phase Two.

BACKGROUND: Questionnaires are widely used in epidemiological studies to measure eczema symptom prevalence, but there are concerns regarding their accuracy if used as a diagnostic tool. OBJECTIVES: To compare the performance of a validated eczema symptom questionnaire and a standardized skin examination protocol employed in the second phase of the International Study of Asthma and Allergies in Childhood (ISAAC). METHODS: A total of 30,358 schoolchildren aged 8-12 years from 18 countries were examined for flexural eczema. Parents also completed an eczema symptom questionnaire. We compared prevalence estimates at the population level based on the questionnaire vs. physical examination. We also compared the skin examination and the ISAAC questionnaire in making a diagnosis of flexural eczema. RESULTS: The point prevalences for flexural eczema at centre level based on a single examination were lower than the questionnaire-based 12-month period prevalences (mean centre prevalence 3.9% vs. 9.4%). Correlation between prevalences of both outcome measures was high (r = 0.77, P < 0.001). At the individual level, questionnaire-derived symptoms of 'persistent flexural eczema in the past 12 months' missed < 10% of cases of flexural eczema detected on physical examination. However, between 33% and 100% of questionnaire-based symptoms of 'persistent flexural eczema in the past 12 months' were not confirmed on examination. CONCLUSIONS: ISAAC questionnaire-derived symptom prevalences are sufficiently precise for comparisons between populations. Where diagnostic precision at the individual level is important, questionnaires should be validated and potentially modified in those populations beforehand, or a standardized skin examination protocol should be used.

Mycophenolate mofetil monotherapy in patients who underwent liver transplantation for hepatitis C cirrhosis.

INTRODUCTION: Mycophenolate mofetil (MMF) monotherapy has recently been proposed for liver transplant recipients with adverse events (nephrotoxicity, hypertension) related to calcineurin inhibitors. We analyzed the influence of MMF on the clinical course of recurrent hepatitis C. METHODS: Among 1038 patients who underwent liver transplantation (OLT) from April 1986 to October 2006, we analyzed 48 adult recipients (4.6%) whose diagnosis was hepatitis C virus (HCV) cirrhosis and who were converted from calcineurin inhibitors to MMF monotherapy. RESULTS: The 36 men and 12 women, had a mean age at OLT of 52.9 +/- 7.2 years; the time elapsed from OLT to the onset of MMF monotherapy was 72.5 +/- 47.6 months (range = 11-210). The mean follow-up after monotherapy was 19 +/- 16.1 months (range = 2-67). Indications for conversion were: chronic renal dysfunction with HCV in 45 patients; HCV recurrence in two; and hypertension plus HCV recurrence in one subject. When the indication was renal dysfunction (excluding three patients who underwent hemodialysis), the mean creatinine values decreased significantly from baseline to 6 months of monotherapy from 1.63 +/- 0.61 mg/dL to 1.51 +/- 0.78 mg/dL (P < .03). The creatinine clearance only improved significantly from the baseline value of 56.6 +/- 16.8 mL/min to the value at 3 months of monotherapy-63.6 +/- 18.4 mL/min (P < .001). At the last outpatient visit, creatinine and creatinine clearances had not changed significantly. The mean diastolic blood pressure did improve significantly at the end of the study. The mean glucose levels decreased but not significantly at the last outpatient visit. Liver function tests did not change significantly after conversion to MMF monotherapy. The acute rejection rate was 8.3%, and adverse events related to MMF monotherapy were present in 9 patients (18.7%). CONCLUSIONS: Conversion from calcineurin inhibitors to MMF monotherapy in patients who underwent OLT for HCV transiently improved renal function and hypertension. The acute rejection rate was low, and adverse events were usually well tolerated.

Influence of dialysis modality on complications and patient and graft survival after pancreas-kidney transplantation.

INTRODUCTION: We investigated whether hemodialysis or peritoneal dialysis prior to pancreas-kidney transplantation was a risk factor for the development of surgical complications, recipient mortality, or graft loss. PATIENTS AND METHODS: From March 1995 to December 2006, 90 patients with type 1 diabetes underwent pancreas transplantation. Dialysis before transplantation was provides to 81 patients. We compared outcomes of recipients classified as two groups: (A) hemodialysis (n = 49, 60.5%) versus (B) peritoneal dialysis (n = 32, 39.5%) groups. RESULTS: Donor and recipient characteristics were similar in both groups. Enteric drainage was more frequently used in the hemodialysis group and bladder drainage in the peritoneal dialysis group (P < .05). The rate of intra-abdominal infections was similar in both groups: 10 patients (20.4%) in the hemodialysis group and 9 patients (28.1%) in the peritoneal dialysis group (P = NS). The incidence of enteric or bladder leakage was slightly higher in the peritoneal dialysis group (5 cases, 15.6% vs 4 cases, 8.2% in the hemodialysis group; P = NS). The rate of reoperations was also slightly higher in the peritoneal dialysis group B (15 cases, 46.9% vs 14 cases, 28.6% in the hemodialysis group; P = .07). Pancreas transplantectomy was significantly greater in the peritoneal dialysis (9 cases; 28.1%) than the hemodialysis group (5 cases; 10.2%; P < .05). The actuarial 3-year patient survival was 95.9% in the hemodialysis group and 93.4% in the peritoneal dialysis group (P = NS); actuarial 3-year pancreas graft survival was 79.3% in the hemodialysis group and 68.3% in the peritoneal dialysis group (P = NS). CONCLUSIONS: We noted an insignificantly greater rate of reoperations but significantly higher incidence of pancreas transplantectomy in the peritoneal dialysis group; however, patient and pancreas graft survivals were similar in both study groups.

[Discrepancy between clinical and radiologic manifestations of an epidural hematoma after catheterization]. / Discordancia clínico-radiológica y resolución espontánea de un hematoma postcateterización epidural.

Neuraxial techniques are considered safe if certain guidelines are followed, but they are not risk free. We report the case of an 81-year-old woman with an invasive bladder tumor who underwent radical cystectomy with a Bricker-type procedure. General anesthesia was used and epidural analgesia was also provided for surgical and postoperative pain management. Late in the postoperative recovery period a large epidural hematoma was diagnosed based on radiologic signs of spinal cord compression, in the absence of symptoms other than mild and progressive back pain that developed after extubation. The surgeon decided against emergency surgery to reduce compression. Symptoms resolved gradually, and a magnetic resonance image 45 days after discharge confirmed that the hematoma was smaller. In addition to the usual safety recommendations for epidural anesthesia with regard to drugs that alter hemostasis, it is important to bear in mind circumstances that have pharmacokinetic repercussions and that increase risk. Lower back pain can be a warning sign. Some cases may resolve spontaneously.
