Factors of poor prognosis in newborns with a prenatal diagnosis of gastroschisis in Bogota, Colombia.

OBJECTIVES: To identify factors associated with poor prognoses in newborns with a prenatal diagnosis of gastroschisis in eight hospitals in Bogota, Colombia, from 2011 to 2022. METHODS: A multi-center retrospective case-control study was conducted on newborns with gastroschisis in eight hospitals in Bogota, Colombia. Poor prognosis was defined as the presence of sepsis, intestinal complications, or death. RESULTS: The study included 101 patients. Preterm newborns under 32 weeks had a poor neonatal prognosis (OR 6.78 95 % CI 0.75-319). Oligohydramnios (OR 4.95 95 % CI 1.15-21.32) and staged closure with silo (OR 3.48; 95 % CI 1.10-10.96) were risk factors for neonatal death, and intra-abdominal bowel dilation of 20-25 mm was a factor for the development of intestinal complications (OR 3.22 95 % CI 1.26-8.23). CONCLUSIONS: Intra-abdominal bowel dilation between 20 and 25 mm was associated with intestinal complications, while oligohydramnios was associated with the risk of perinatal death, requiring increased antenatal surveillance of fetal wellbeing. Management with primary reduction when technically feasible is recommended in these infants, considering that the use of silos was associated with higher mortality.

Effect of probiotics on glucose levels and weight gain in mice exposed to low doses of malathion.

INTRODUCTION: Owing to its ability to reduce the toxicity of environmental pollutants that are risk factors for diabetes and obesity, the use of probiotic bacteria might aid the treatment of these diseases. OBJECTIVE: To determine the effects of chronic exposure to low-dose malathion on weight and glucose levels in mice, as well as to evaluate the protective role of a probiotic supplement. METHODS: Weight and serum glucose levels of four groups of mice (control, malathion-exposed [10 ppm], probiotics and malathion + probiotics) were determined every 10 days for 180 days. RESULTS: Malathion administration induced an increase in weight and glucose levels in the malathion group mice in comparison with the other groups. CONCLUSIONS: Consumption of food contaminated with malathion residues increases glucose levels and favors weight gain, while consumption of probiotics reduces the effects generated by residues in food.

INTRODUCCIÓN: Debido a su capacidad para reducir la toxicidad de contaminantes ambientales que constituyen factores de riesgo de diabetes y obesidad, el uso de bacterias probióticas podría ayudar al tratamiento de esas enfermedades. OBJETIVO: Determinar los efectos de la exposición crónica a malatión a dosis bajas sobre el peso y los niveles de glucosa de ratones, así como evaluar el papel protector de un suplemento probiótico. MÉTODOS: Cada 10 días se determinó el peso y la glucosa sérica de cuatro grupos de ratones (de control, expuestos a malatión (10 ppm), probióticos y malatión + probióticos) durante 180 días. RESULTADOS: La administración de malatión provocó un incremento del peso y los niveles de glucosa en los ratones del grupo con malatión comparados con los demás grupos. CONCLUSIONES: El consumo de alimentos contaminados con residuos de malatión aumenta los niveles de glucosa y favorece el incremento del peso; el consumo de probióticos disminuye los efectos generados por los residuos en los alimentos.

Comparison of wire versus Nylon in Bonny-Mallet Finger treated with pull-out surgery.

INTRODUCTION: Zone I extensor tendon lesion accompanies an avulsion fracture of the bone insertion. A common complication of traditional pull-out is the necrosis of the site of the button in the finger pad. Zhang described an alternative way of anchoring the cerclage to the Kirschner Wire (K-wire) to relieve the pressure in the finger pad. He describes the use of wire cerclage, for fracture reduction. The objective of this paper is to perform a comparison between wire and nylon using Zhang pull-out technique. MATERIAL AND METHODS: We performed a cohort study comparing Nylon versus Wire in Zhang technique. Comparing cosmetic satisfaction, stiffness, residual pain, and Crawford scale. RESULTS: When comparing the outcomes between both groups, we found no statistical difference in cosmetic satisfaction (p = 0.285), stiffness (p = 0.460), and residual pain (p =1.000), overall complications (p = 1.000), or Crawford scale (p = 1.000). We only found a significant statistical difference in pain when removing the cerclage, being greater in Group B (p = 0.008). CONCLUSIONS: We found no significant outcome difference between nylon and wire cerclage. However, at the time of removing it, patients experience less pain.

INTRODUCCIÓN: Una complicación común del pull-put tradicional es la necrosis del sitio del botón en la yema del dedo. Zhang describió una forma alternativa de anclar el cerclaje al clavo de Kirschner para aliviar la presión en la yema del dedo. Describe el uso de cerclaje de alambre para la reducción de fracturas. El objetivo de este trabajo es realizar una comparación entre el alambre y el nailon utilizando la técnica de extracción de Zhang. MATERIAL Y MÉTODOS: Realizamos un estudio de cohorte comparando la técnica de nailon versus alambre en Zhang. Comparación de satisfacción cosmética, rigidez, dolor residual y escala de Crawford. RESULTADOS: Al comparar los resultados entre ambos grupos, no encontramos diferencias estadísticas en la satisfacción cosmética (p = 0.285), rigidez (p = 0.460) y dolor residual (p = 1.000), complicaciones generales (p = 1.000) o escala de Crawford (p = 1.000). Solo encontramos una diferencia estadística significativa en el dolor al retirar el cerclaje, siendo mayor en el Grupo B (p = 0.008). CONCLUSIONES: No encontramos diferencias significativas en los resultados entre el cerclaje de nailon y el cerclaje con alambre. Pero, al momento de retirarlo, los pacientes experimentan menos dolor. Tipo de estudio: terapéutico Nivel de evidencia III.

Intestinal obstruction secundary to gallstone ileus: case report.

Gallstone ileus is an intestinal obstruction that is secondary to the presence of gallstones in the small intestine. It is a rare complication of cholelithiasis, which represents 1-3% of the causes of intestinal obstruction. The diagnosis is difficult given that the symptoms are nonspecific with intermittent intestinal obstruction, Rigler's triad (pneumobilia, stone and abdominal distention) is pathognomonic. Among the diagnostic aids are abdominal radiography, ultrasound and abdominal tomography. Treatment should be individualized depending on the patient's conditions, with laparotomy with enterotomy being the treatment of choice.

El íleo biliar es una obstrucción intestinal secundaria a la presencia de cálculos biliares en el intestino delgado. Es una complicación rara de la colelitiasis y representa el 1-3% de las causas de obstrucción intestinal. El diagnóstico es difícil dado que la clínica es inespecífica, con un cuadro de oclusión intestinal intermitente; la tríada de Rigler (neumobilia, lito y distensión abdominal) es patognomónica. Dentro de los auxiliares diagnósticos se encuentran la radiografía de abdomen, el ultrasonido y la tomografía computarizada abdominal. El tratamiento debe individualizarse dependiendo de las condiciones del paciente, siendo de elección la laparotomía con enterotomía.

Plasmacytoid variant of urothelial carcinoma of the bladder manifesting as bilateral ureteral and small bowel obstruction.

Plasmacytoid urothelial carcinoma (PUC) is a rare variant of bladder cancer characterized by distinct histopathology and advanced stage at diagnosis. Multimodal treatment is usually indicated. We present a case of PUC causing bilateral ureteral obstruction with subsequent renal failure followed shortly by malignant small bowel obstruction, demonstrating the need for a high degree of clinical suspicion in diagnosis of this aggressive subtype. Moreover, the local invasiveness of the disease cannot be understated, given that it can rapidly spread with little radiologic evidence of progression until it is at an advanced stage.

Impact of the new kidney allocation system A2/A2B → B policy on access to transplantation among minority candidates.

Blood group B candidates, many of whom represent ethnic minorities, have historically had diminished access to deceased donor kidney transplantation (DDKT). The new national kidney allocation system (KAS) preferentially allocates blood group A2/A2B deceased donor kidneys to B recipients to address this ethnic and blood group disparity. No study has yet examined the impact of KAS on A2 incompatible (A2i) DDKT for blood group B recipients overall or among minorities. A case-control study of adult blood group B DDKT recipients from 2013 to 2017 was performed, as reported to the Scientific Registry of Transplant Recipients. Cases were defined as recipients of A2/A2B kidneys, whereas controls were all remaining recipients of non-A2/A2B kidneys. A2i DDKT trends were compared from the pre-KAS (1/1/2013-12/3/2014) to the post-KAS period (12/4/2014-2/28/2017) using multivariable logistic regression. Post-KAS, there was a 4.9-fold increase in the likelihood of A2i DDKT, compared to the pre-KAS period (odds ratio [OR] 4.92, 95% confidence interval [CI] 3.67-6.60). However, compared to whites, there was no difference in the likelihood of A2i DDKT among minorities post-KAS. Although KAS resulted in increasing A2/A2B→B DDKT, the likelihood of A2i DDKT among minorities, relative to whites, was not improved. Further discussion regarding A2/A2B→B policy revisions aiming to improve DDKT access for minorities is warranted.

Factores de riesgo para endometritis puerperal en pacientes que asisten para terminación del embarazo en el hospital Simón Bolivar entre enero 2007 a diciembre 2013 / Risk factors for puerperal endometritis in patients attending for termination of pregnancy at Simón Bolivar hospital between january 2007 to december 2013

La endometritis Posparto constituye la causa más frecuente de fiebre puerperal, y su incidencia aumenta con la presencia de ciertos factores de riesgo que se pueden encontrar en todos los niveles de atención de la gestante y su identificación, permitiría disminuir la morbimortalidad en los servicios de Ginecología y Obstetricia. OBJETIVO Determinar los factores de riesgo para endometritis puerperal en el servicio de Ginecología y Obstetricia del Hospital Simón Bolívar. MATERIALES Y MÉTODOS Se realizó un estudio observacional tipo analítico retrospectivo de casos y controles en el Hospital Simón Bolívar de la ciudad de Bogotá, en mujeres que asistieron durante el periodo comprendido entre Enero de 2007 a Diciembre de 2013 para terminación del embarazo durante el tercer trimestre. RESULTADOS Se analizaron un total 408 pacientes, 136 pacientes con endometritis postparto (casos) y 272 pacientes sin endometritis (controles), con una relación caso control de 1 caso por cada 2 controles. Al realizar el análisis de las variables a estudio como: paridad, ruptura de membranas, vía del parto, índice de masa corporal, revisión uterina, infección de vías urinarias y presencia de flujo vaginal, asociado a endometritis no mostraron resultados estadísticamente significativos. La asociación entre la edad de la madre, edad gestacional al momento del parto y preeclampsia evidenciaron un ligero aumento del riesgo para endometritis puerperal. CONCLUSIÓN Los principales factores de riesgo para endometritis puerperal encontrados entre las pacientes atendidas por servicio de Ginecología y Obstetricia del Hospital Simón Bolívar fueron gestantes de edad avanzada, pacientes con preeclampsia asociada y edad gestacional menor de 37 semanas al momento del parto. La vía de parto y la atención intraparto no tuvieron asociación ni aumento del riesgo de forma significativa.

Morbimortalidad materno-perinatal en pacientes con infección por VIH, Hospital Simón Bolívar, 2003-2011, Bogotá (Colombia) / Maternal and perinatal morbidity and mortality in patients with HIV infection at Hospital Simón Bolívar, 2003-2011, Bogotá (Colombia)

Objetivo: describir la morbilidad y mortalidad materna y perinatal asociadas a la infección por VIH en el Hospital Simón Bolívar entre el año 2003 y el 2011. Materiales y métodos: estudio descriptivo de cohorte histórica. Se incluyeron pacientes gestantes con diagnóstico confirmado de infección por VIH que asistieron al control prenatal y a quienes se les atendió el parto y el puerperio entre enero de 2003 y diciembre de 2011, en el Hospital Simón Bolívar, institución de tercer nivel de complejidad, centro de referencia para pacientes con VIH, ubicado en el noroccidente de Bogotá. Se realizó muestreo consecutivo y se evaluaron las características sociodemográficas y clínicas basales, y la morbilidad materna durante la gestación, al momento del parto o el puerperio, como también la morbilidad perinatal. Se realizó análisis descriptivo de la morbilidad por medio de proporciones y análisis exploratorio de la asociación entre el recuento de linfocitos CD4 y la carga viral con los resultados maternos y perinatales. Resultados: un total de 136 pacientes tenían diagnóstico de VIH confirmado en la institución, de estas se obtuvo información completa en 106 (78 %). No hubo ningún caso de muerte materna y se presentaron 2 casos de muerte fetal in utero. Las principales comorbilidades maternas encontradas fueron anemia (18 %), ETS (22,6 %), neumonía (5,7 %) y fiebre puerperal (4,7 %). Las comorbilidades perinatales más frecuentes fueron bajo peso al nacer (21,7 %) y convulsiones (2,8 %). No se encontró asociación entre la carga viral y el recuento CD4 con la morbilidad materna o perinatal. Conclusión: la paciente gestante con infección por VIH presenta en general un ligero aumento de las complicaciones maternas y perinatales. Es importante realizar nuevos estudios en los diferentes grupos poblacionales para poder valorar adecuadamente todas estas asociaciones.

Objective: To describe maternal and perinatal HIV-associated morbidity and mortality at Simón Bolívar Hospital between 2003 and 2011. Materials and methods: A descriptive historical cohort study. The study included pregnant women with a confirmed diagnosis of HIV infection attending prenatal control visits and receiving care during delivery and the postpartum period, between January 2003 and December 2011 at the Simon Bolívar Hospital, a general, level-III referral centre for HIV patients, located in northwest Bogota. Sampling was done consecutively and the assessment included baseline social, demographic and clinical characteristics; maternal mortality during pregnancy, at the time of delivery and during the postpartum period; and perinatal mortality. A descriptive morbidity analysis was conducted using proportions, together with an exploratory analysis of the association between the CD4 lymphocyte count and viral load, and maternal and perinatal outcomes. Results: Overall, 136 patients had a confirmed diagnosis of HIV at the institution, and complete information was obtained for 106 (78%) of them. There were no cases of maternal deaths and 2 foetal deaths in utero. The main maternal comorbidities found were anaemia (18%), STDs (22.6%), pneumonia (5.7%) and postpartum fever (4.7%). The most frequent perinatal comorbidities were low birth weight (21.7%), and seizures (2.8%). No association was found between viral load and CD4 count and maternal or perinatal morbidity. Conclusion: Pregnant women with HIV infection generally present a slight increase in maternal and perinatal complications. It is important to undertake additional studies in different population groups in order to arrive at an appropriate evaluation of all these associations.

No benefit when placing drains after kidney transplant: a complex statistical analysis.

OBJECTIVES: This paper sought to determine if there were an association between drain placement and the incidence of wound complications. MATERIALS AND METHODS: A single-center institutional review board-approved retrospective study between 2001 to 2008, comparing 680 kidney transplant patients who either had a drain placed or were left undrained. Linear regression modeling was used to adjust the risk factors between the groups. Patients received calcineurin inhibitors, steroids, and a mycophenolate formulation. The incidence of early major and minor wound complications were captured. Minor wound complications were defined as seroma, lymphocele, and perigraft fluid collection, and major wound complications were defined as wound dehiscence, hematomas, evisceration, infections, wound necrosis, and hernias. Patients with incomplete data or those taking sirolimus were excluded. RESULTS: Six hundred eighty kidney transplant cases were reviewed. Four hundred seventy-nine received drains; 201 did not. Demographic analyses revealed that the drain group had a higher average value in age and body mass index. The drain group had a lower albumin and a lower mean platelet count after surgery. The number of patients without diabetes in the drain group numbered nearly twice as many as did those without drains. An attempt was made to statistically account for demographic differences. Seventy-eight of 479 drained patients (16.28%) and 24 of 201 no-drain patients (11.94%) had a wound complication. Minor wound complications were observed in 9 patients (1.88%) in the drain group and 6 in no-drain group (2.99%) (P = .3702). Major wound complications were observed in 58 patients in the drain group (12.18%) and 17 in the no-drain group (8.46%) (P = .1655). Drain placement had no effect on major or minor wound complications. CONCLUSIONS: Drain placement is not associated with major or minor wound complications in kidney transplants.

Validez del parcial de orina y el Gram en el diagnóstico de infección del tracto urinario en el embarazo. Hospital Simón Bolívar, Bogotá, Colombia, 2009-2010 / Validity of urinalysis and Gram staining in the diagnosis of urinary tract infections in pregnancy. Hospital Simón Bolívar, Bogotá, Colombia, 2009-2010

Objetivo: determinar la exactitud diagnóstica del parcial de orina y la tinción de Gram en el diagnóstico de infección del tracto urinario (ITU) en el embarazo. Materiales y métodos: estudio de validez diagnóstica en pacientes embarazadas hospitalizadas, con alta sospecha de ITU, en el servicio de Ginecología y Obstetricia del Hospital Simón Bolívar, Centro de III Nivel de atención, entre el 1 de enero de 2009 y el 31 de diciembre de 2010. El parcial de orina, sus parámetros –estearasa leucocitaria, bacteriuria, leucocituria, nitritos– y la tinción de Gram se compararon con el urocultivo considerado como patrón de oro diagnóstico. Se llevó a cabo un muestreo no probabilístico por conveniencia. El cálculo de tamaño de muestra se realizó mediante Epidat 4.0 con sensibilidad mínima esperada del 80%, especificidad mínima esperada del 90% y un nivel de confianza del 90% para la prevalencia establecida en la literatura del 20%. Se calculó la sensibilidad, la especificidad, el valor predictivo positivo (VPP), valor predictivo negativo (VPN), además de la razón de probabilidades (RP + y RP -). Resultados: un total de 212 muestras de pacientes embarazadas fueron incluidas en el estudio de las cuales 115 (54%) presentaron urocultivo positivo y 97 (46%) negativo. El 78% de las pacientes presentaron pielonefritis, mientras el 22% se presentaron con ITU baja (cistouretritis). El principal germen encontrado fue la Escherichia coli en el 70% de las pacientes. El Gram tuvo una sensibilidad del 74% (IC 95%: 65-81) y una especificidad del 86% (IC 95%: 78-92), el parcial de orina mostró una sensibilidad del 21% (IC 95%: 14-29) y una especificidad de 92% (IC 95%: 84-96). Conclusión: las pruebas rápidas que se realizan en el servicio de urgencias fueron altamente específicas en el diagnóstico de ITU en pacientes embarazadas. El Gram es la prueba con mayor sensibilidad para el diagnóstico de ITU en las pacientes gestantes del Hospital Simón Bolívar.

Objective: To determine the diagnostic accuracy of urinalysis and Gram staining the diagnosis of urinary tract infection (UTI) in pregnancy. Materials and methods: Diagnostic validity study in pregnant women with a high suspicion of UTI, hospitalized in the Obstetrics and Gynecology Service of the Simon Bolivar Hospital, a Level III center, between January 1st 2009 and December 31st 2010. Gram staining and urinalysis with its parameters (leukocyte esterase, bacteriuria, leukocyturia, nitrites) were compared with urine culture, considered as the gold standard test. Specificity, sensitivity, positive predictive value (PPV) and probability ratios (LR + and PR -) were calculated. A non-probabilistic sampling was done out of convenience. The sample size was calculated using the Epidat 4.0, with a minimum expected sensitivity of 90% and a confidence level of 90% for the prevalence of 20% established in the literature. Results: Of the total of 212 samples of pregnant women included in the study, 115 (54%) had a positive urine culture and 97 (46%) had a negative culture. Seventy-eight per cent of patients presented with pyelonephritis, while 22% presented with low UTI (cystourethritis). The most frequent germ was Escherichia coli, found in 70% of patients. Gram stain had a sensitivity of 74% (95% CI: 65-81) and a specificity of 86% (95% CI: 78-92); urinalysis had a sensitivity of 21% (95% CI: 14-29) and a specificity of 92% (95% CI: 84-96). Conclusion: Rapid tests done in the emergency room showed high specificity for the diagnosis of UTI in pregnant women. Gram staining is the test with the highest sensitivity for the diagnosis of UTI in this population at Hospital Simón Bolívar.

Evaluating safety and efficacy of rabbit antithymocyte globulin induction in elderly kidney transplant recipients.

OBJECTIVES: The optimal immunosuppression regimen for elderly kidney transplant recipients is poorly defined. We sought to evaluate the short-term efficacy and safety of thymoglobulin in geriatric recipients of deceased-donor kidneys. MATERIALS AND METHODS: A single-center, retrospective analysis was undertaken between elderly (≥ 65 years) (n=137) and nonelderly (n=276) kidney transplant recipients who received rabbit antithymocyte globulin induction and calcineurin inhibitor, mycophenolic acid, and prednisone maintenance. RESULTS: The mean age was 70 versus 52 years. Fewer elderly patients had an earlier transplant or panel reactive antibodies > 20%, but had more machine perfused, older, and extended criteria donor kidneys. Elderly patients received lower rabbit antithymocyte globulin (5.4 vs 5.6 mg/kg; P = .04) and initial mycophenolic acid doses (1620 vs 1774 mg; P = .002), and experienced less delayed graft function (31.1% vs 50.0%; P < .001). Death-censored graft survival and graft function at 3 years and biopsy-proven acute rejection at 1 year were comparable; however, there was lower 3-year patient survival in elderly patients. Donor age was the only factor associated with reduced patient survival. Rates of malignancy, infection, or thrombocytopenia were similar; however, leukopenia occurred less frequently in elderly patients (11.7% vs 19.9%; P = .038). CONCLUSIONS: Elderly kidney transplant recipients receiving rabbit antithymocyte globulin did not experience different short-term graft survival, graft function or rates of infection, malignancy or hematologic adverse reactions than did nonelderly patients; they experienced fewer episodes of delayed graft function, but had lower 3-year patient survival.

Successful Treatment of Rapid Onset, Symptomatic de novo Non-alcoholic Steatohepatitis Following Liver Transplantation: A Case Report.

A 45 year old female with a body mass index (BMI) of 24 underwent successful liver transplantation (LT) for alcoholic cirrhosis using a donor liver from an obese woman with microvesicular steatosis (80%) and minimal macrovesicular steatosis (5-10%) on liver biopsy. Ascites and hepatosplenomegaly developed soon after LT with progressive increase of serum alkaline phosphatase to 1340 IU/L while aspartate aminotransferase (AST), and alanine transaminase (ALT), and total bilirubin remained normal. Imaging showed marked hepatomegaly, extensive fatty infiltration of the liver, and compression of the hepatic veins with narrowing of the intrahepatic inferior vena cava (IVC). Liver biopsy on post-operative day 39 revealed 90-100% macrovesicular steatosis, steatohepatitis, and portal fibrosis. A hepatic venogram showed a 10 cm segment of intrahepatic IVC stenosis that was stented, improving portal venous pressure measurements. However, portal hypertension requiring diuretic therapy and multiple paracenteses remained. By 3 months after LT, her liver had grown to 22 cm, transaminases increased 2-4 times the upper limit of normal with a 2:1 AST to ALT ratio. Liver biopsy at post-LT day 82 showed no change in steatosis and steatohepatitis despite corticosteroid withdrawal and interval periportal and perisinusoidal fibrosis. 12 weeks after LT, the patient was found to have low apolipoprotein B (65 mg/dL), high-density lipoprotein (HDL) (<10 mg/dL), low-density lipoproteins (LDL) (9 mg/dL), and total cholesterol (<50 mg/dL) levels. Therapy was started for NASH with high dose (800 IU daily) vitamin E and pioglitazone 15 mg daily, and she received topical vegetable oil and oral essential fatty acid supplements. Liver enzymes normalized after 3 months and her lipid profile improved markedly (HDL 27 mg/dL, total cholesterol 128 mg/dL), with progressive decrease in liver size and resolution of ascites after 5 months of therapy. At 2 years post-LT, the liver enzymes remain normal and lipids have normalized.

Operative start times and complications after kidney transplantation.

The worldwide focus on work hour regulations and patient safety has led to the re-examination of the merits of night-time surgery, including kidney transplantation. The risks of operating during nontraditional work hours with potentially fatigued surgeons and staff must be weighed against the negative effects of prolonged cold ischemic time with resultant graft compromise. The aim of this study was to evaluate the impact of performing renal transplantation procedures during evening versus day time hours. The main outcome measures assessed between the day and night cohorts included comparisons of the postoperative complication rates and survival outcomes for both the renal allograft and the patient. A retrospective review of 633 deceased donor renal transplants performed at a single institution was analyzed. Three statistically significant results were noted, namely, a decrease in vascular complications in the nighttime cohort, an increase in urologic complications on subgroup analysis in the 3 AM to 6 AM cohort, and the 12 AM to 3 AM subgroup had the greatest odds of any complication. There was no statistical difference in either patient or graft survival over a twelve month period following transplantation. We conclude that although the complication rate varied among cohorts this was clinically insignificant and there was no overall clinically relevant impact on patient or graft survival.

Uso del heberprot–P como tratamiento coadyuvante en la evolución postoperatoria de la enfermedad pilonidal / The use of heberprot–p as coadjuvant treatment in the postoperative evolution of pilonidal disease

La enfermedad pilonidal es un trastorno muy frecuente en el medio, que afecta sobre todo a varones entre la segunda y la tercera décadas de la vida. Constituye un gran problema socioeconómico y médico pues incide sobre el núcleo de población laboralmente activa, motiva períodos de ausencia laboral, así como por su cronicidad y recidiva. En la actualidad se han descrito diversas variantes de manejo terapéutico, muchas prolongan la atención médica y el uso de material sanitario para su evolución y cura definitiva, lo que ocasiona el alza de los costos económicos y sociales para el paciente y personal médico. Con el incremento en el país del uso del Heberprot–P, que se basa en el factor de crecimiento humano recombinante, y su uso por angiólogos para el manejo del pie diabético casi de forma exclusiva, se ha abierto un espectro para el manejo de otras lesiones con el objetivo de lograr la cicatrización. Se presenta un paciente con fístula pilonidal recidivante, tratada de forma quirúrgica sin cierre primario, donde se utilizó el Heberprot–P con fines cicatrizantes, el cual tuvo una evolución satisfactoria y se presenta como alternativa para el manejo de esta enfermedad.

The pilonidal disease is a very common disorder that affects men between the second and third decades of life. It is a great socio-economic and medical problem to affect the nucleus of working adult population motivating labor loss periods and also by its chronicity and recurrence. Currently they have described several variants of therapeutic management; many extend health care and the use of medical supplies for its evolution and definitive cure with the rise of the economic and social costs for the patient and healthcare providers. With the development advent in the country the use of the Heberprot - P, which is based on the factor of recombinant human growth for the management of the diabetic foot almost exclusive, it has opened a spectrum for the management of other injuries aimed at healing. A patient is presented with recurrence pilonidal fistula treated in a surgical way without primary closure where the Heberprot - P was used with healing purposes that he presented a satisfactory evolution and is presented as an alternative for this disease management.

Tumores estromales: a propósito de un caso / Stromal tumors: apropos of a case

Se presenta un caso de aparición poco frecuente atendido en el Departamento de Gastroenterología del Hospital Provincial Docente Dr Antonio Luaces Iraola de Ciego de Ávila. Se trata de una paciente femenina, 73 años de edad, que acude a consulta con vómitos frecuentes, de contenido bilioso, sobre todo después de la ingestión de alimentos, cambios en el hábito intestinal y síndrome general marcado, y al examen físico se palpa en abdomen una masa de aspecto T en región hipogástrica, grande, no dolorosa a la palpación, movible. Se realizaron estudios pertinentes y se arribó al diagnóstico de tumor de intestino delgado. Se realizó cirugía abdominal con exéresis del tumor, se realiza el estudio histológico y se obtiene el diagnóstico tumor del estroma intestinal fusocelular.

A case of rare appearance is presented in the Department of Gastroenterology of the Provincial teaching Hospital Dr. Antonio Luaces Iraola Ciego de Ávila. It's a female patient, 73 years of age, who comes to consultation with frequent vomiting of bilious content, especially after the ingestion of food, changes in bowel habit and marked general syndrome, and a mass of T aspect in hypogastric region is palpable in abdomen to the physical examination, big, not painful to palpation, movable. Relevant studies were carried out and tumor of small intestine was the diagnosis. Abdominal surgery with exeresis of the tumor was coductive, The histological study is carried out and gets the diagnostic spindle-cell intestinal stromal tumor.

Metronidazole-induced encephalopathy in a patient with end-stage liver disease.

Purpose. Metronidazole-induced encephalopathy (MIE) has been rarely reported. We report a case in a patient with end-stage liver disease (ESLD). Summary. A 63-year-old male with ESLD secondary to hepatitis C virus presented with progressively worsening fatigue, slurred speech, aphasia, vomiting, and left-sided facial droop after completing a 2-week course of metronidazole for recurrent Clostridium difficile-associated diarrhea. He completed a previous course of metronidazole 3 weeks prior to presentation. He is on the liver transplant waiting list and has known hepatic encephalopathy. MRI revealed hyperintense T2 signals involving the bilateral dentate nuclei, inferior colliculi and splenium of the corpus callosum, and increased diffusion restriction at the splenium of the corpus callosum. His neurological function improved over the next several days. He underwent liver transplantation 6 days after admission. A follow-up MRI 6 weeks after presentation revealed resolution of abnormalities; however, paresthesias persisted 6 months after MIE diagnosis. Conclusion. An ESLD patient with hepatic encephalopathy developed MIE after a relatively short course of metronidazole. Metronidazole has been shown to accumulate in patients with ESLD. Increased awareness for neurotoxicity when using metronidazole in ESLD patients is warranted, especially in those with potentially confounding hepatic encephalopathy.

Cistrome: an integrative platform for transcriptional regulation studies.

The increasing volume of ChIP-chip and ChIP-seq data being generated creates a challenge for standard, integrative and reproducible bioinformatics data analysis platforms. We developed a web-based application called Cistrome, based on the Galaxy open source framework. In addition to the standard Galaxy functions, Cistrome has 29 ChIP-chip- and ChIP-seq-specific tools in three major categories, from preliminary peak calling and correlation analyses to downstream genome feature association, gene expression analyses, and motif discovery. Cistrome is available at http://cistrome.org/ap/.
