Antitumor Necrosis Factor Agents to Treat Endoscopic Postoperative Recurrence of Crohn's Disease: A Nationwide Study With Propensity-Matched Score Analysis.

INTRODUCTION: Patients with Crohn's disease experiencing endoscopic postoperative recurrence (POR) may benefit from antitumor necrosis factor (TNF) agents but scarce data on this are available. Our aim was to assess the efficacy of anti-TNF in improving mucosal lesions in patients with endoscopic POR. METHODS: Multicenter, retrospective, study of patients with Crohn's disease who underwent therapy with anti-TNF agents for endoscopic POR (Rutgeerts score > i1). Treatment outcomes were assessed by the findings in the last ileocolonoscopy performed after anti-TNF therapy was initiated. Endoscopic improvement and remission were defined as any reduction in the baseline Rutgeerts score and by a Rutgeerts score < i2, respectively. RESULTS: A total of 179 patients were included, 83 were treated with infliximab and 96 with adalimumab. Median time on anti-TNF therapy at the last endoscopic assessment was 31 months (interquartile range, 13-54). Endoscopic improvement was observed in 61%, including 42% who achieved endoscopic remission. Concomitant use of thiopurines and treatment with infliximab were associated with endoscopic improvement (odds ratio [OR] 2.15, 95% confidence interval [CI] 1.04-4.46; P = 0.03, and OR 2.34, 95% CI 1.18-4.62; P < 0.01, respectively) and endoscopic remission (OR 3.16, 95% CI 1.65-6.05; P < 0.01, and OR 2.01, 95% CI 1.05-3.88; P = 0.04, respectively) in the multivariable logistic regression analysis. These results were confirmed in a propensity-matched score analysis. DISCUSSION: In patients with endoscopic POR, anti-TNF agents improve mucosal lesions in almost two-thirds of the patients. In this setting, concomitant use of thiopurines and use of infliximab seem to be more effective in improving mucosal lesions.

Chronic total occlusion percutaneous coronary intervention in Latin America.

OBJECTIVES: To report clinical, angiographic characteristics, outcomes, and predictors of unsuccessful procedures in patients who underwent chronic total occlusion (CTO) percutaneous coronary interventions (PCI) in Latin America. BACKGROUND: CTO PCI has been increasingly performed worldwide, but there is a lack of information in this region. METHODS: An international multicenter registry was developed to collect data on CTO PCI performed in centers in Latin America. Patient, angiographic, procedural and outcome data were evaluated. Predictors of unsuccessful procedures were assessed by multivariable analysis. RESULTS: We have included data related to 1,040 CTO PCIs performed in seven countries in Latin America (Argentina, Brazil, Chile, Colombia, Ecuador, Mexico, and Puerto Rico). The mean age was 64 ± 10 years, and CTO PCI was performed mainly for angina control (81%) or treatment of a large ischemic area (30%). Overall technical success rate was 82.5%, and it was achieved with antegrade wire escalation in 81%, antegrade dissection/re-entry in 8% and with retrograde techniques in 11% of the successful procedures. Multivariable analysis identified moderate/severe calcification, a blunt proximal cap and a previous attempt as independent predictors of unsuccessful procedures. In-hospital major adverse cardiovascular events (MACE) occurred in 3.1% of the cases, death in 1% and cardiac tamponade in 0.9% CONCLUSIONS: CTO PCI in Latin America has been performed mainly for ischemia relief. Procedures were associated with a success rate above 80% and low incidence of MACE. Predictors of unsuccessful procedures were similar to those previously reported in the literature.

Adalimumab or Infliximab for the Prevention of Early Postoperative Recurrence of Crohn Disease: Results From the ENEIDA Registry.

BACKGROUND: Anti-tumor necrosis factor agents (anti-TNFs) are efficacious at preventing the postoperative recurrence (POR) of Crohn disease, as demonstrated in 2 randomized controlled trials. However, real-life data for infliximab or adalimumab in this setting are scarce. Our aim was to assess both the efficiency of anti-TNFs at preventing early POR of Crohn disease in clinical practice and the associated risk factors for POR. METHODS: Patients in whom anti-TNFs were prescribed for the prevention of POR within 3 months after ileocolonic resection and who had an endoscopic assessment within 18 months were identified from the ENEIDA registry. Clinical and endoscopic features were collected within 18 months after surgery. RESULTS: In total, 152 patients were included (55 treated with infliximab, 97 with adalimumab, and 39% with concomitant immunosuppressants). Anti-TNF treatment was started after a median time of 29 days (IQR 13-44) after surgery. Eighty-two percent of patients had at least one risk factor for POR, and 82% had been exposed to anti-TNFs before the index surgery. Overall, 34% had endoscopic POR (as defined using a Rutgeerts endoscopic score > i1); 14% had advanced endoscopic POR (>i2); and 20% had clinical POR, with no differences between infliximab and adalimumab. In the multivariate analysis, only perianal disease (odds ratio 2.73, 95% confidence interval [CI] 1.26-5.91) and rectal involvement (odds ratio 2.79, 95% CI 1.09-7.14) were independent predictors of endoscopic POR. CONCLUSIONS: In clinical practice, anti-TNFs for the prevention of POR of Crohn disease are frequently used in patients experienced with anti-TNFs and with concomitant immunosuppressants. The efficacy of infliximab and adalimumab for POR prevention is similar and in accordance with the results obtained in randomized controlled trials.

Frank intrabiliary rupture in liver hydatidosis located in the hilar plate: a surgical challenge.

BACKGROUND: Frank intrabiliary rupture (FIR) is a severe complication that occurs in around 30% of patients with liver hydatidosis. When FIR is present, the contents of the cyst may pass into the common bile duct and cause a variety of complications. If the FIR is located in the hilar confluence, surgical repair is a challenge. Currently there are no data regarding its optimum treatment. MATERIAL AND METHODS: Between May 2007 and December 2012, we treated 59 patients with liver hydatidosis. Four patients, all women, with a mean age of 51.7 years, had hydatid cysts located between segments IVb and V and FIR affecting the hilar plate. In 3 cases, the initial clinical condition was obstructive jaundice. The fourth patient presented recurrence after having undergone two operations as a child. RESULTS: In each patient a major hepatectomy was performed with hilar plate reconstruction (3 left and 1 right). Morbidity included mild biliary fistula (1 patient) and abdominal collection resolved by percutaneous drainage (1 patient). There was no mortality. During follow-up (47 months), no recurrences of the disease or biliary strictures were recorded. CONCLUSIONS: FIR is a severe complication of liver hydatidosis. When it is located in the hilar confluence, liver resection may be the best surgical option for definitive resolution of the problem.

Prevalencia de controles prenatales incompletos en un servicio de maternidad y su relación con complicaciones neonatales / Prevalence of prenatal complete care in a Maternity and their relationship to neonatal complications

El control prenatal reduce la morbilidad y mortalidad materna y perinatal, partos prematuros y el número de productos con bajo peso al nacer, a la vez que permite identificar factores de riesgo, lo cual hace posible establecer acciones preventivas y terapéuticas oportunas durante el embarazo. Se considera control prenatal completo (CPC) al que cumple con las siguientes premisas: precoz, periódico, completo y de amplia cobertura. Con el objetivo de determinar la prevalencia de CPC en la población de embarazadas que consultaron al servicio de maternidad del hospital “Ángela I. de Llano” y establecer la relación entre el número de controles y complicaciones neonatales precoces, se llevó a cabo un estudio retrospectivo en el que se analizaron las historias clínicas del periodo junio a diciembre de 2010. Sobre 823 mujeres incluidas en el estudio, el 51% no presentó controles que cumplieran con los criterios de precocidad,cantidad, distribución, integralidad y calidad; las complicaciones neonatales fueron mayores en el grupo de controles incompletos. El 6,2% de los recién nacidos en el grupo sin control presentó bajo peso. El ingreso a neonatología fue del 9,7% en el grupo de controles incompletos y del 4,9% en el de controles completos. El porcentaje de óbitos fetales fue del 1,1% en el grupo de controles incompletos. Puede concluirse que los controles prenatales en la población estudiada se asocian con un mejor control y salud fetal neonatal, menor número de complicaciones y menos óbitos y fetos muertos, lo cual coincide con lo encontrado enotros lugares del país y de Latinoamérica.

Prenatal care reduces morbidity and both maternal and perinatal mortality, premature births and the number of products with low birth weight; additionally, it helps to identify risk factors making possible to establish appropriate preventive and therapeutic actions during pregnancy. Prenatal care is considered complete with the following premises: early, periodic, complete and comprehensive coverage. To determine the prevalence of complete prenatal care (CPC) among pregnant women and to establish the relationship between the number of controls and early neonatal complications, we performed a retrospective study analyzing the medical records of the Service of Maternity of the Hospital “Angela I. Llano”, in a period from June to December 2010.Among 823 studied women, the 51% had no controls that met the criteria of precocity, quantity, distribution, integrity and quality, so we can also see that neonatal complications were higher in the group of controls incomplete. We found that the 6.2% of newborns in the uncontrolled group had low birth weight. The entrance to the nursery was 9.7% in the control group and 4.9% among the incomplete control group.The percentage of stillbirths was 1.1% in the incomplete control group. In conclusion, we found that prenatal care was associated with better fetal control and neonatal health, fewer complications, deaths and stillbirths, which agree with that found elsewhere in the country and Latin America

Walled-off pancreatic necrosis.

Acute severe pancreatitits may be complicated by the development of 'walled-off pancreatic necrosis' (WOPN), which is characterised by a mixture of solid components and fluids on imaging studies as a consequence of organised pancreatic tissue necrosis. We present here an overview of the definition, clinical features, and diagnostic and therapeutic management of this clinical condition, which is mostly based on consensus as adequate clinical trials are lacking.

Results of laparoscopic cholecystectomy in a third-level university hospital after 17 years of experience.

OBJECTIVE: The aim of the study is to determine the results obtained with laparoscopic cholecystectomy at Ramón y Cajal Hospital after 17 years of experience, comparing current results with those at the beginning of the experience. MATERIAL AND METHODS: Between 1991 and December 2007, 3,933 laparoscopic cholecystectomies were performed at the "Ramón y Cajal Hospital"; 1,849 patients were operated on between 1991 and 2000, and 2,084 between 2001 and 2007. Patients studied included 69.8% of women and 30.2% of men, with a mean age of 56.95 years (range 9-94 years). In all, 54.68% of patients had a concomitant disease before surgery (hypertension, diabetes, ischemic heart disease, respiratory disease). Surgery was performed by a staff surgeon for 58.04% of cases, and by a resident in the remaining 41.96%. Surgical indications were cholelithiasis in 75.5%, pancreatitis in 13.3%, cholecystitis in 6.3%, choledocholithiasis in 3.05%, and others in 1.2% of cases. RESULTS: Mean hospital stay was 3.06 days. Conversion to open surgery was required for 8.3% of cases (331 patients). The major surgical complication rate was 2.34%, with the most frequent being hemoperitoneum (1%). Common bile duct injury occurred in thirteen cases (0.3%), 51 patients (1.3%) were soon re-operated, and 5 patients died (0.13%). When the results of both decades (1991-2000 vs. 2001-2007) were compared, we observed differences in the number of procedures performed by residents (31.7 vs. 51.1%, p = 0.00001), number of laparoscopic cholecystectomies for cholecystitis (4.9 vs. 7.53%, p = 0.001), conversion rate (5.46 vs. 11%, p = 0.000001), and mean hospital stay (2.43 vs. 3.7 days, p = 0.001). CONCLUSION: These results should be interpreted with caution as this is a retrospective study with multiple uncontrolled variables (high number of surgeons and continuous learning curve). The lower conversion rate and mean hospital stay in the first decade of the learning curve are amazing, although this could be related to better patient selection and a lower number of cholecystites operated using a laparoscopic approach in the initial series. In general, these results are acceptable and concur with the rest of the literature.

Comparative performance of a combined injectable contraceptive (50 mg norethisterone enanthate plus 5mg estradiol valerate) and a combined oral contraceptive (0.15 mg levonorgestrel plus 0.03 mg ethinyl estradiol) in adolescents.

STUDY OBJECTIVE: To compare in a regular non-clinical trial experience the efficacy, acceptability, and continuation rates of an injectable contraceptive containing 50 mg norethisterone enanthate plus 5mg estradiol valerate (IC) and an oral contraceptive containing 0.15 mg levonorgestrel plus 0.03 mg ethinyl estradiol (OC), among adolescent users. DESIGN: A total of 251 adolescents ages 14-19 were followed during 12 months. The IC group (124 subjects) was studied for 1044 cycles and the OC group (127 subjects) was studied for 1368 cycles. The users were not assigned in a random selection. Information was collected from clinical records. Groups were compared using Pearson chi-square, odds ratio (95% confidence interval), t-test, and proportion difference test. RESULTS: The IC group had significant differences in baseline social risk, confidence, psychiatric problems, consumption of alcohol, and number of sexual partners. At 12 months, the IC group showed significant decrease in weight and increase in hypermenorrhea. In the OC group, dysmenorrhea decreased, and hypomenorrhea and regular cycles were significantly more frequent. One pregnancy occurred in the OC group (Pearl Index: 0.88). Final continuation rates at 12 months were 41.9% and 37.8% for IC and OC, respectively. CONCLUSIONS: The monthly injectable is a recommended contraceptive option for adolescents, especially for those facing psychosocial risk factors.

Resultados de la colecistectomía laparoscópica en un hospital universitario de tercer nivel tras 17 años de experiencia / Results of laparoscopic cholecystectomy in a third-level university hospital after 17 years of experience

Objetivo: el objetivo del estudio es conocer los resultados obtenidos con la colecistectomía laparoscópica en el Hospital Ramón y Cajal en sus 17 años de experiencia, comparando los resultados actuales con los del inicio de la experiencia. Material y métodos: entre enero de 1991 y diciembre de 2007 se efectuaron en el Hospital Ramón y Cajal un total de 3.933 colecistectomías laparoscópicas. Fueron intervenidos 1.849 pacientes entre 1991-2000 y 2.084 entre 2001-2007. Un 69,8% eran mujeres y un 30,2% varones con una edad media de 56,95 años (rango 9-94 años). Un 54,68% de pacientes presentaban antecedentes personales de forma previa a la intervención (hipertensión, diabetes, cardiopatía isquémica, bronquitis...). La cirugía fue efectuada por un personal del staff en el 58,04% de los casos y por un residente de cirugía en el 41,96%. Las indicaciones quirúrgicas fueron colelitiasis 75,5%, pancreatitis 13,3%, colecistitis 6,3%, coledocolitiasis 3,05% y otros 1,2%. Resultados: la estancia media postoperatoria fue de 3,06 días. La tasa de conversión a cirugía abierta de 8,3% (331 pacientes) y la de complicaciones quirúrgicas mayores del 2,34%, siendo la más frecuente el hemoperitoneo (1%). Se produjeron 13 lesiones de la vía biliar durante la cirugía laparoscópica (0,3%), 51 pacientes (1,3%) fueron reintervenidos precozmente tras la cirugía (hemo-/coleperitoneo) y fallecieron un total de 5 pacientes (0,13%). Cuando comparamos los resultados entre ambas décadas (1991-2000 vs. 2001-2007), observamos que existen diferencias estadísticamente significativas en cuanto al número de intervenciones realizadas por el residente (31,7 vs. 51,1%, p = 0,00001), el número de colecistitis abordadas por vía laparoscópica (4,9 vs. 7,53%, p = 0,001), la tasa de conversión (5,46 vs. 11%, p = 0,000001) y la estancia media postoperatoria (2,43 días vs. 3,7 días p = 0,001)...(AU)
