[Detection of adverse events in thyroid and parathyroid surgery using trigger tool and Minimum Basic Data Set (MBDS)]. / Detección de eventos adversos en la cirugía tiroidea y paratiroidea utilizando la herramienta trigger y el Conjunto Mínimo de Datos Básicos (CMBD).

OBJECTIVES: To compare the ability of the trigger tool) and the Minimum Basic Data Set (MBDS) in detecting adverse events (AE) in hospitalized surgical patients with thyroid and parathyroid disease. METHODS: A descriptive, cross-sectional observational study, retrospective and cross-sectional study was conducted from May 2014 to April 2015 analysing retrospectively data on of patients submitted to thyroidectomy and parathyroidectomy in order to detect AE through the identification of triggers (an event often associated to an AE) and the MBDS. triggers and AE were located by systematic review of clinical documentation. The MBDS was got from the data base. Once an AE was detected, it was characterized. RESULTS: 203 AE were identified in 251 patients, being the 90.04% detected by trigger tool and 10.34% by MBDS. 126 patients had at least one AE (50.2%). Without the cases in which uncontrolled pain was the only AE, the percentage of patients that suffering AE was 38.65%. 187 AE were considered preventable and 16 AE were considered unpreventable. The trigger tool and the MBDS demonstrated a sensitivity of 91.27 and 13.49%, a specificity of 4.8 and 100%, a positive predictive value of 49,15 and 100%, and a negative predictive value of 35.29 and 53.42%, respectively. The triggers with more predictive power in AE detection were «antiemetic administration¼ and «calcium administration¼. CONCLUSIONS: Trigger tool shows higher sensitivity for detecting AE than the MBDS. All the detected AE were considered low severity and most of them were preventable.

Does a 6-point scale approach to post-treatment 18F-FDG PET-CT allow to improve response assessment in head and neck squamous cell carcinoma? A multicenter study.

PURPOSE: Response assessment to definitive non-surgical treatment for head and neck squamous cell carcinoma (HNSCC) is centered on the role of 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET-CT) 12 weeks after treatment. The 5-point Hopkins score is the only qualitative system available for standardized reporting, albeit limited by suboptimal positive predictive value (PPV). The aim of our study was to explore the feasibility and assess the diagnostic accuracy of an experimental 6-point scale ("Cuneo score"). METHODS: We performed a retrospective, multicenter study on HNSCC patients who received a curatively-intended, radiation-based treatment. A centralized, independent qualitative evaluation of post-treatment FDG-PET/CT scans was undertaken by 3 experienced nuclear medicine physicians who were blinded to patients' information, clinical data, and all other imaging examinations. Response to treatment was evaluated according to Hopkins, Cuneo, and Deauville criteria. The primary endpoint of the study was to evaluate the PPV of Cuneo score in assessing locoregional control (LRC). We also correlated semi-quantitative metabolic factors as included in PERCIST and EORTC criteria with disease outcome. RESULTS: Out of a total sample of 350 patients from 11 centers, 119 subjects (oropharynx, 57.1%; HPV negative, 73.1%) had baseline and post-treatment FDG-PET/CT scans fully compliant with EANM 1.0 guidelines and were therefore included in our analysis. At a median follow-up of 42 months (range 5-98), the median locoregional control was 35 months (95% CI, 32-43), with a 74.5% 3-year rate. Cuneo score had the highest diagnostic accuracy (76.5%), with a positive predictive value for primary tumor (Tref), nodal disease (Nref), and composite TNref of 42.9%, 100%, and 50%, respectively. A Cuneo score of 5-6 (indicative of residual disease) was associated with poor overall survival at multivariate analysis (HR 6.0; 95% CI, 1.88-19.18; p = 0.002). In addition, nodal progressive disease according to PERCIST criteria was associated with worse LRC (OR for LR failure, 5.65; 95% CI, 1.26-25.46; p = 0.024) and overall survival (OR for death, 4.81; 1.07-21.53; p = 0.04). CONCLUSIONS: In the frame of a strictly blinded methodology for response assessment, the feasibility of Cuneo score was preliminarily validated. Prospective investigations are warranted to further evaluate its reproducibility and diagnostic accuracy.

Organs at risk's tolerance and dose limits for head and neck cancer re-irradiation: A literature review.

Re-irradiation is becoming an established treatment option for recurrent or second primary head and neck cancer(HNC). However, acute and long-term RT-related toxicities could dramatically impact patients' quality of life. Due to the sparse literature regarding HNC re-irradiation, data on tolerance doses for various organs at risk (OARs) are scarce. Our aim was to systematically review the clinical literature regarding HNC re-irradiation, focusing on treatment toxicity, OARs tolerance, and dose limit recommendations. Thirty-nine studies (three randomized, five prospective, 31 retrospective) including 3766 patients were selected. The median interval time between the first course and re-irradiation was 28  months (range, 6-90). In 1043 (27.6%) patients, postoperative re-irradiation was performed. Re-irradiation doses ranged from 30 Gy in 3 fractions using stereotactic technique to 72 Gy in conventional fractionation using intensity-modulated radiotherapy. Pooled acute and late toxicityrates ≥G3 were 32% and 29.3%, respectively. The most common grade 3-4 toxic effects were radionecrosis, dysphagia requiring feeding tube placement and trismus. In 156 (4.1%) patients, carotid blowout was reported. Recommendations for limiting toxicity included the time interval between radiation treatments, the fractionation schedules, and the re-irradiation treatment volumes. Cumulative dose limit suggestions were found and discussed for the carotid arteries, temporal lobes, and mandible.

Escisión Mesorrectal Total Transanal (Tatme): Aspectos Prácticos De La Técnica Quirúrgica / Transanal Total Mesorectal Excision: Practical Aspects Of Surgical Technique

INTRODUCCIÓN: El cáncer de recto es la séptima neoplasia más frecuente en España con una incidencia de 12570 casos/100.000 hab/año. La supervivencia a 5 años en Europa es del 55-62 % y tiende a aumentar gracias a la introducción de cambios en el tratamiento y nuevas técnicas quirúrgicas. La TaTME permite visualizar directamente el margen distal del tumor, evita las dificultades técnicas que aparecen al introducir las endograpadoras lineales en pelvis estrechas para seccionar el recto y ofrece una visualización directa de las estructuras pélvicas durante la EMT. El objetivo de este estudio es describir la técnica quirúrgica de la TaTME minuciosamente destacando los aspectos más prácticos del procedimiento. MATERIAL Y MÉTODOS: Se ha realizado una búsqueda bibliográfica sistemática en la base de datos Cochrane, MEDLINE y EMBASE mediante los términos "transanal total mesorectal excision". RESULTADOS: Durante la fase transanal se coloca el dispositivo gel-point monopuerto y multicanal transanal para la creación del neumorrecto. La luz del recto se cierra mediante una sutura en bolsa de tabaco. Tras completar la rectotomía se procede a la escisión mesorrectal total. Para la fase abdominal se crea un neumoperitoneo. Los vasos mesentéricos inferiores se seccionan en origen. Una vez que ambos equipos han avanzado en la escisión mesorrectal los campos se comunican abriendo el por el plano anterior. Se pueden construir varios tipos de anastomosis colorrectales. CONCLUSIÓN: La TaTME es un tratamiento quirúrgico del cáncer de recto medio y bajo seguro y factible

INTRODUCTION: Rectal cancer is the seventh most common cancer in Spain with an incidence of 12570 cases/100000 h/year. The 5-year overall survival of rectal cancer in Europe was 55-62% and this rate tends to improve due to new challenges and the development of new surgical techniques. TaTME offers a direct vision of the distal end of tumour, it avoids technical difficulties for in-troducing staplers down a narrow pelvis and it improves a direct visualization of pelvic structures during total mesorectal excision. The aim of this study is to describe the surgical technique for TaTME selecting the most practical aspects of this procedure. MATERIAL AND METHODS: The relevant studies were identified by a search of MEDLINE, EMBASE and Cochrane Oral Health Group Specialized Register using terms transanal total mesorectal excision. RESULTS: During transanal phase pneumorectum is created using Gel Point Path Transanal Access platform. The rectal lumen is closed with a purse.string suture. After a complete rectotomy the total mesorectal excision is performed circumferentially. Pneu-moperitoenum is created for abdominal phase. When transanal and abdominal teams have achieved a complete total mesorectal excision both planes are connected at the anterior plane. Several types of colorectal anastomosis can be performed. CONCLUSIÓN: TaTME is a secure and feasible surgical treatment for low-mid rectal cancer

Bariatric Surgery Waiting Lists in Spain.

Bariatric surgery is one of the most common general surgery procedures in countries that, like Spain, have public healthcare systems, but is also one of the procedures for which patients have to wait the longest. The Spanish Society of Obesity Surgery (SECO) conducted a survey to estimate the situation of bariatric surgery waiting lists in Spain's public hospitals and to gather information on a number of related aspects. METHODS: An online survey was sent to the members of the SECO. The survey received 137 visits, all via the click-through link provided, from 52 health centers (47 public and 5 private). The data collected were included in a database and later analyzed using the SPSS18.0 statistical software package. RESULTS: A total of 4724 patients were on bariatric surgery waiting lists (BWLs), at an average of 100 per public hospital. Sixty-eight percent had been waiting for more than 6 months. The mean delay per patient was 397 days, and the longest wait was 1661 days. A further 46.2% of respondents were able to recall cases of patients who in the past 5 years had suffered cardiovascular events with sequelae while awaiting surgery, and 21.2% recalled at least one fatal cardiovascular event in that time. CONCLUSION: Our data revealed an unacceptably long wait for obesity surgery. Notwithstanding the limitations and potential biases of our research, the long wait for surgery in our context inevitably has serious consequences for a potentially significant number of patients.

Impact on patient outcome of emergency department length of stay prior to ICU admission / Impacto pronóstico de la duración de la estancia en el Servicio de Urgencias antes del ingreso en la UCI

OBJECTIVE: The favorable evolution of critically ill patients is often dependent on time-sensitive care intervention. The timing of transfer to the intensive care unit (ICU) therefore may be an important determinant of outcomes in critically ill patients. The aim of this study was to analyze the impact upon patient outcome of the length of stay in the Emergency Care Department. DESIGN: A single-center ambispective cohort study was carried out. SETTING: A general ICU and Emergency Care Department (ED) of a single University Hospital. PATIENTS: We included 269 patients consecutively transferred to the ICU from the ED over an 18-month period. INTERVENTIONS: Patients were first grouped into different cohorts based on ED length of stay (LOS), and were then divided into two groups: (a) ED LOS ≤5h and (b) ED LOS >5h. VARIABLES: Demographic, diagnostic, length of stay and mortality data were compared among the groups. RESULTS: Median ED LOS was 277min (IQR 129-622). Patients who developed ICU complications had a longer ED LOS compared to those who did not (349min vs. 209min, p < 0.01). A total of 129 patients (48%) had ED LOS >5h. The odds ratio of dying for patients with ED LOS >5h was 2.5 (95% CI 1.3-4.7). Age and sepsis diagnosis were the risk factors associated to prolongation of ED length of stay. CONCLUSIONS: A prolonged ED stay prior to ICU admission is related to the development of time-dependent complications and increased mortality. These findings suggest possible benefit from earlier ICU transfer and the prompt initiation of organ support

OBJETIVO: La evolución de los pacientes críticos se relaciona con intervenciones que dependen del tiempo. Por tanto, el momento de traslado de los pacientes graves a la UCI puede relacionarse con el pronóstico. El objetivo de este estudio fue analizar el impacto de la duración del ingreso en Urgencias sobre el pronóstico de los pacientes. DISEÑO: Estudio de cohortes ambispectivo de centro único. Ámbito: UCI polivalente y Servicio de Urgencias de un Hospital Universitario. PACIENTES: Un total de 269 pacientes ingresados en la UCI consecutivamente desde urgencias durante 18meses. INTERVENCIONES: Se agrupó a los pacientes en cohortes según la duración del ingreso en urgencias. Después se dividieron en 2 grupos: a)estancia en urgencias ≤5h, y b)estancia en urgencias >5h. VARIABLES: Demográficas, diagnóstico, estancia, mortalidad. RESULTADOS: Mediana de estancia en urgencias de 277min (RIC129-622). Los pacientes que desarrollaron complicaciones en la UCI tuvieron mayor estancia en Urgencias que aquellos sin complicaciones (349 vs. 209min, p < 0,01). Un total de 129 pacientes (48%) tuvieron un ingreso en urgencias >5h. La odds ratio para el fallecimiento hospitalario de los pacientes con un ingreso en urgencias >5h fue de 2,5 (IC del 95%, 1,3 a 4,7). La edad y la sepsis fueron los factores de riesgo asociados a la prolongación del ingreso en urgencias. Conclusiones Una estancia prolongada urgencias antes del ingreso en la UCI se relaciona con el desarrollo de complicaciones que dependen del tiempo y con la mortalidad. Estos hallazgos sugieren un beneficio del ingreso precoz en la UCI y del inicio de soporte orgánico sin retraso

Reservorios venosos subcutáneos tipo port-a-cath. Ventajas del acceso quirúrgico mediante venotomía cefálica / Port-A-Cath implantable venous access system. Advantages ofsurgical access by cephalic venotomy

Introducción: La colocación de dispositivos implantables permanentes ha aumentado exponencialmente debido al aumento de indicaciones. El objetivo de este artículo es demostrar las ventajas de la utilización de la disección de vena cefálica para la colocación de sistemas venosos centrales. Métodos: Estudio longitudinal, descriptivo y retrospectivo, en el cual analizamos 265 pacientes consecutivos, recogidos entre enero de 2010 y octubre de 2013, a los que se les colocó un reservorio venoso subcutáneo mediante venotomía de la vena cefálica en el surco deltopectoral como acceso primario. Se detallan complicaciones intraoperatorias y postoperatorias tempranas y tardías. Resultados: En 253 pacientes se canaliza la vena cefálica, representando una tasa de éxito del 95,5 %. No se asocian complicaciones intraoperatorias como neumotórax o hemotórax. La tasa de complicaciones tempranas es el del 4 %, y tardías del 11,5 %, con un seguimiento mínimo de ocho meses. Se asociaron a retirada del sistema en 14 pacientes. Conclusión: El acceso por vena cefálica en régimen de cirugía mayor ambulatoria es seguro, con una alta tasa de éxito en nuestro estudio, y con una tasa de complicaciones tempranas y tardías bajas igual al acceso mediante punción sin riesgo de neumo-hemotórax (AU)

Introduction: The use of totally implantable access ports has increased exponentially due to the increase of indications. The objective of this article is to demonstrate the advantages of using surgical venous cutdowns of the cefalic vein to place central venous systems. Patients and methods: Longitudinal, descriptive and retrospective study, which analyzed 265 consecutive patients, collected between January 2010 and October 2013. In these patients a subcutaneous venous reservoir was placed by opening the cephalic vein in the deltopectoral groove as primary access. Intraoperative and postoperative early and late complications were documented in detail. Results: The primary success rate was 95.5 % for the venous cutdowns. No intraoperative complications such as pneumothorax or haemothorax were associated. The early complication rate is 4 %; late complications rate is 11.5 %, with a minimum follow-up of eight months. In 14 cases the complications were associated with the removal of the system. Conclusion: The surgical venous cutdown in ambulatory surgery is safe, with a high success rate in our study, and a rate of early and late complications like puncture of the subclavian vein approach, without risk of pneumo-haemothorax (AU)

Chronic intestinal pseudo-obstruction: a diagnosis to be considered.

Chronic intestinal pseudoobstruction (CIPO) is a rare entity characterized by recurrent clinical episodes of intestinal obstruction in which no mechanical cause is identified. There are multiple causes for this syndrome but two main groups can be distinguished: a) secondary to a systemic non-gastrointestinal disease; and b) primary or idiopathic originated from alterations in the components of the intestinal wall. The latter forms are the most uncommon and their diagnosis is generally difficult. In the present article, we describe nine patients with CIPO that were diagnosed in our center over the last six years. Four of them were diagnosed with primary or idiopathic form of CIPO and another four were clearly secondary to a systemic disease. The ninth case, which was initially diagnosed as secondary, is probably also a primary form of the disease. The number of patients diagnosed in our center, even thought small, makes us to hypothesize that the prevalence of CIPO is probably greater than is generally believed and that the reasons of its rarity are the incomplete understanding of its physiopathology and the difficulties to achieve a correct diagnosis.

Roles of NCX and PMCA in basolateral calcium export associated with mineralization cycles and cold acclimation in crayfish.

Basolateral Na+/Ca2+ exchanger (NCX) and plasma membrane Ca2+ ATPase (PMCA) are the primary transmembrane proteins that export calcium (Ca2+) from cells. In our lab we use a nonmammalian animal model, the freshwater crayfish, to study cellular Ca2+ regulation. Two experimental conditions are employed to effect Ca2+ dyshomeostasis: (a) in the postmolt stage of the crustacean molting cycle increased unidirectional Ca2+ influx associated with cuticular mineralization is accompanied by elevated basolateral Ca2+ export (compared with intermolt Ca balance); and (b) exposure of the poikilothermic crayfish to cold acclimation (4 degrees C) causes influx of Ca2+ into cells, which is compensated by increased basolateral Ca2+ export (compared with exposure to 23 degrees C). This study compares expression of both NCX and PMCA mRNA (real-time PCR) and protein (Western) in both epithelial (kidney) and nonepithelial tissue (tail muscle) during elevated basolateral Ca2+ export. Both experimental treatments produced increases in NCX and PMCA expression (mRNA and protein) in both tissues. Mineralization produced greater upregulation of mRNA in kidney than in tail, whereas cold acclimation yielded comparable increases in both tissues. Protein expression patterns were generally confirmatory of real-time PCR data although expression changes were less pronounced. Both experimental treatments appear to increase basolateral Ca2+ export.

Marjolin's ulcer arising from a laparostomy scar.

Marjolin's ulcer is the malignant transformation of a scar, usually as a squamous cell carcinoma. An uncommon presentation form is from a laparostomy scar. A 49-year-old patient that had a laparostomy during the treatment of a necrohemorrhagic pancreatitis in 1987 complained 13 years later of a 20-cm ulcer on the laparostomy scar. A resection of the abdominal wall including the ulcer and a segmental transverse colectomy were performed because of infiltration by an invasive squamous cell carcinoma. Ten months later, axillary lymphadenectomy was performed because of lymph node metastasis. Currently, the patient is free of disease. Lymph node infiltration is frequent in squamous cell carcinoma on Marjolin's ulcer and survival is not good. Prophylaxis of this disease includes meticulous care of wounds, with early skin grafts when required and treatment of infections.
