Preoperative care of Polypoid exposed mucosal template in bladder exstrophy: the role of high-barrier plastic wraps in reducing inflammation and polyp size

ABSTRACT Objective To assess the role of high-barrier plastic wrap in reducing the number and size of polyps, as well as decreasing the inflammation and allergic reactions in exstro- phy cases, and to compare the results with the application of low-barrier wrap. Materials and Methods Eight patients with bladder exstrophy-epispadias complex (BEEC) that had used a low density polyethylene (LDPE) wrap for coverage of the exposed polypoid bladder in preoperative care management were referred. The main complaint of their parents was increase in size and number of polyps. After a period of 2 months using the same wrap and observing the increasing pattern in size of polyps, these patients were recommended to use a high-barrier wrap which is made of polyvinylidene chloride (PVdC), until closure. Patients were monitored for the number and size of polyps before and after the change of barriers. The incidence of para-exstrophy skin infection/inflammation and skin allergy were assessed. Biopsies were taken from the polyps to identify histopathological characteristics of the exposed polyps. Results The high barrier wrap was applied for a mean ± SD duration of 12±2.1 months. Polyps' size and number decreased after 12 months. No allergic reaction was detected in patients after the usage of PVdC; three patients suffered from low-grade skin allergy when LDPE was applied. Also, pre-malignant changes were observed in none of the patients in histopathological examination after the application of PVdC. Conclusion Polyps' size and number and skin allergy may significantly decrease with the use of a high-barrier wrap. Certain PVdC wraps with more integrity and less evaporative permeability may be more "exstrophy-friendly".

New bowel preparation technique for colonoscopy: clinical trial comparing aquanet and mannitol / Nova técnica de preparo intestinal para colonoscopia: estudo clínico comparativo entre aquanet e manitol

ABSTRACT Background: Fifty-five percent of Americans aged 50-65 are submitted to colonoscopy. For over 65-year, this number increases to 64%. In Brazil, it is forecast that the population submitted to colonoscopy will grow, even though inadequate preparation is still a major problem. Aim: To analyze the quality of a new intestinal preparation technique, Aquanet EC-2000®, compared to oral Mannitol solution. Methods: This prospective longitudinal study enrolled 200 patients with indication for colonoscopy. The sample was randomly allocated to two groups of 100; one group received Aquanet EC-2000® to prepare for colonoscopy and the other Mannitol solution. The Boston scale was used to analyze the results. Results: As expected both preparations produced similar results with the bowel cleansing of the different regions of the colon being classified as Boston scale 3 (excellent) in most patients (p>0.05). Conclusion: The results of bowel preparation using Aquanet EC-2000® were similar to using Mannitol solution.

RESUMO Racional: Cinquenta e cinco por cento dos norte-americanos entre 50-65 anos fazem colonoscopia. Acima de 65 anos o número foi de 64%. No Brasil, estima-se crescente aumento da população submetida à colonoscopia, apesar da preparação inadequada ainda ser um grande problema. Objetivo: Analisar e comparar a qualidade do novo método de preparo intestinal por meio do Aquanet EC-2000® frente ao uso de solução oral de Manitol. Método: Por randomização 200 pacientes foram divididos em dois grupos de 100. Um recebeu Aquanet EC-2000® e o outro Manitol. O presente estudo seguiu modelo prospectivo longitudinal por meio da seleção de 200 pacientes com indicação à colonoscopia, formando dois grupos de 100. Para analisar os resultados foi utilizada a escala de Boston. Resultados: Ambos os preparos foram estatisticamente significativos com p<0,05. A escala 3 de Boston foi a mais frequente para ambos os métodos.Além disso, na estatística aplicada às diferentes regiões do cólon para ambos os procedimentos as proporções observadas concordaram com o esperado (3-excelente). Conclusão: Os resultados do preparo intestinal utilizando Aquanet EC-2000® foram semelhantes aos do Manitol.

Effect of presurgical orthopedics on oral-health related quality of life in chilean children with cleft lip and palate. a pilot study / Efecto de la ortopedia prequirúrgica sobre la calidad de vida relacionada con salud oral en niños chilenos con fisura labio palatina. estudio piloto

Abstract: the aim of this pilot study was to evaluate the effect of Presurgical Orthopedics (PSO) on the oral health-related quality of life (OHRQoL) in Children with Cleft Lip and Palate (CLP) treated in two hospitals in Chile using the Spanish version of the Child Oral Health Impact Profile (COHIP-Sp). Method: Cross-sectional study, involving 42 children with CLP (mean age 12 +/- 2.1 years; 28 men) who attended their annual checkup at the main Hospital of Valdivia and at the Hospital Fundacion Gantz in Santiago, Chile, between March and April 2016. Those who met the selection criteria were applied the COHIP-Sp scale. Based on their medical records, patients who used PSO as treatment protocol were classified as "PSO". Those who did not receive treatment with the appliance were classified as "Non- PSO". The score of the COHIP-Sp scale and its domains between the two groups was compared (t-test, p<0.05). Results: Twenty-five patients (59.5 percent) used PSO. COHIP-Sp score was 91.7 +/- 26.2 points in the PSO group, and 81.2 +/- 30.9 points in the Non-PSO group. There was no statistically significant difference (p=0.24). Conclusion: OHRQoL of patients with CLP treated with PSO was similar to that of patients not treated with PSO.

Resumen: el objetivo de este estudio piloto fue evaluar el efecto de la Ortopedia Pré-Quirúrgica Infantil (OPQI) sobre la calidad de vida relacionada con salud oral (CVRSO) en niños con Fisura Labio Palatina (FLP) tratados en dos hospitales de Chile usando la versión española del Child Oral Health Impact Profile (COHIP-Sp). Método: Estudio de corte transversal. Participaron 42 niños y niñas con FLP (edad promedio 12 +/- 2.1 años; 28 hombres) que asistieron a su control anual del Hospital Base de Valdivia y la Fundación Gantz en Santiago entre marzo y abril del año 2016. A quienes cumplieron los criterios de selección, se les aplicó la escala COHIP-Sp. Basándose en las fichas clínicas, se clasificó como "OPQI" aquellos pacientes que usaron OPQI como protocolo de tratamiento; y como grupo "No-OPQI" aquellos que no recibieron el tratamiento con la placa. Se comparó el puntaje de la escala COHIP-Sp y sus dominios entre ambos grupos (t-test, p<0.05). Resultados: Veinticinco pacientes (59.5 por ciento) usaron OPQI. La puntuación COHIP-Sp fue 91.7 +/- 26.2 puntos en el grupo OPQI y 81.2 +/- 30.9 puntos en grupo No-OPQI, diferencia estadísticamente no significativa (p=0.24). Conclusión: La CVRSO de pacientes con FLP tratados con OPQI fue similar a pacientes no tratados con OPQI.

One or two screws in the fracture of the odontoid process? Evaluation using computed tomography / Um ou dois parafusos na fratura do processo odontoide? Avaliação pela tomografia computadorizada / Uno o dos tornillos en la fractura del proceso odontoides? Evaluación por tomografia axial computadorizada

Objective: To evaluate the bone area of the odontoid process through computed tomography and its relation with the area of one and two screws in the male and female subjects. Methods: 188 CT scans of adults were analyzed. The isthmus area was selected and the transverse diameter was measured at 1.2 mm from the base of odontoid. Results: After placement of a screw, the odontoid area remains with 82% of free bone for both men and women. With two screws, 45.6% of women, had a free bone area of the odontoid process between 50% and 75% and 54.4% were above 75%. 26.6% men had percentage from 50% to 75% of free bone area and 73.4% above 75% (p=0.07). After the placement of two screws, the bone area was, in average, 77.3% in men and 75.4% in women. Using the Student t-test, the differences between the average of percentage of free bone area in men and women are significantly lower in women (p=0.0012). Conclusion: The pre-operative planning through CT can help to choose the number of screws in the odontoid process. The choice should be particularly careful when using two screws in women.

Objetivo: Avaliar a área óssea do processo odontoide, por meio de tomografia computadorizada e sua relação com a área de um e dois parafusos em indivíduos do sexo masculino e feminino. Métodos: Foram analisadas 188 tomografias computadorizadas de adultos. A área do istmo foi selecionada e o diâmetro transverso foi medido a 1,2 mm da base do odontoide. Resultados: Após a colocação de um parafuso, a área do odontoide permanece com 82% de osso livre, tanto para homens quanto para mulheres. Com dois parafusos, 45,6% das mulheres, passaram a ter área óssea livre do processo odontoide entre 50% e 75%, e 54,4% ficaram acima de 75%. Entre os homens este percentual foi de 26,6% entre 50% a 75% de área óssea livre e 73,4% acima de 75% (valor de p = 0,07). Após a colocação de dois parafusos, a área óssea foi, em média, 77,3% nos homens e 75,4% nas mulheres. Utilizando o teste t de Student, as diferenças entre as médias de homens e mulheres dos percentuais da área óssea livre são significativamente menores nas mulheres (valor de p = 0,0012). Conclusão: O planejamento no pré-operatório, por meio de TC, pode ajudar na escolha do número de parafusos no processo odontoide. A escolha deve ser criteriosa, especialmente quando for necessária a utilização de dois parafusos no gênero feminino.

Uso del dispositivo de asistencia respiratoria Novalung® como puente a trasplante pulmonar: Caso clínico / Bridge to lung transplantation with a novel pumpless lung assist device: Report of one case

Devices such as Novalung® can be used as a bridge to lung transplantation while waiting for a suitable donor. We report a 50 year-old male with a terminal pulmonary fibrosis and candidate for lung transplantation. He was admitted to the hospital due to a severe deterioration of his respiratory condition, with the presence of severe respiratory acidosis despite conventional invasive respiratory support. Respiratory support with Novalung® was started, resulting in a progressive reduction ofpCOz that became normal ten hours after the installation of the device. Five days later a successful lung transplantation wasperformed.

Core needle biopsy of palpable breast lump: the influence of needle size

The diagnostic value of core needle biopsy is increasingly being preferred because of its better characterization of benign and malignant lesions and lower frequency of insufficient samples. The aim of this study was to determine the diagnostic accuracy and complication rates with 2 different gauges of core biopsy needle in the preoperative diagnosis of palpable breast lumps. A total of 150 consecutive core biopsies were included in this prospective non-randomised study of palpable breast lump from May 2000 to May 2001. The tissue diagnosis made from the core biopsy specimen was compared with the final histopathology reports from the excised specimen. However, if the lump is not excised, a presumptive diagnosis of benign lesion was made only after at least 6 months follow up with no change in the breast lump. The data were analysed for sensitivity, specificity, predictive values, diagnostic accuracy and complications. The results from the 2 different sizes of core needle biopsies were compared accordingly and a statistical analysis was performed using Chi-squared test. Ninety-six core specimens were acquired with 14 G needle while the other 54 with 16 G needle. There was no significant statistical difference between the accuracy of both needle sizes. However, 4 complications occurred with the larger size 14 G needle while none with the 16 G needle, but this was not statistically significant. In conclusion the size 16 G core biopsy needle provided an accurate diagnostic reliability that is comparable to the larger size 14 G needle in the preoperative diagnosis of palpable breast lump.

Criterios de selección de la anestesia en la paciente ginecoobstétrica grave / Anesthesia selection criteria for the gynecological and obstetrical patient

Se realizó un estudió retrospectivo en 30 pacientes ginecoobstétricas que ingresaron a la Unidad de Cuidados Intensivos, con el objetivo de valorar cuántas de ellas fueron quirúrgicas y por lo tanto requirieron de anestesia así como valorar los criterios de selección de la misma en la enferma de alto riesgo o grave. Se describen el número de intervenciones quirúrgicas realizadas, el tipo y el tiempo de cirugía correlacionándolas con los métodos, técnicas, tipos y tiempos anestésicos. Para analizar los criterios de selección de la anestesia se recurrió a las clasificaicones de la ASA, y Goldman, al estado de compensación o descompensación del padecimiento, al estado de conciencia de las enfermas, al estado del feto in útero antes de la cirugia y a los requerimentos anestésicos de las enfermas de acuerdo a las condiciones citadas y a las necesidades de analgesia, protección neurovegetativa, hipnosis y relajación muscular. También se analizó el monitoreo utilizado pre, trans y posoperatoriamente, además de las complicaciones trans y posanestésicas que se presentaron con los métodos elegidos. De acuerdo con los resultados encontrados, se recomiendan los métodos y técnicas de anestesia a seguir en pacientes de alto riesgo

Medida indireta da pressäo arterial em funçäo da largura do manguito, em pacientes nas fases pré-operatória imediata, recepçäo no centro cirúrgico e pós anestésica / Measure of blood pressure in function of sizes of cuffs, in patients in mediate perioperative phase, reception area of operation room and posoperative phase

Este estudo visou comparar em pacientes submetidos a cirurgias, medidas de pressäo arterial obtidas com duas larguras de manguito: a largura padräo, de 12cm, usada internacionalmente, e a largura correspondente a 0,38 da medida da circunferência do braço, recomendada pela American Heart Association, para evitar hiper ou hipoestimaçäo nos valores obtidos por ocasiäo do registro da pressäo arterial. As comparaçöes foram efetuadas nas fases pré-operatória imediata, recepçäo no centro cirúrgico e pós anestésica, tendo em vista, a importância de se detectar alteraçöes com o máximo de precisäo, num período de avaliaçäo geral das condiçöes impostas pelo ato cirúrgico. Os resultados obtidos confirmam diferenças significantes (p<0,0001) entre as duas larguras de manguitos utilizados, atingindo em alguns indivíduos 30 mmHg hipoestimaçäo nos valores sistólicos e diastólicos.
