ABSTRACT

Resumen Objetivo Comunicar la experiencia en el tratamiento de pectus excavatum en el Instituto Nacional del Tórax. Material y Método: Estudio descriptivo con seguimiento. Se recolectaron datos de las variables de interés, mediante la revisión de fichas clínicas. Se incluyeron pacientes operados entre marzo de 2007 y abril de 2018. Resultados Se incluyeron 86 pacientes operados con técnica mínimamente invasiva en el período descrito. De ellos, 74 pacientes de sexo masculino. El promedio de edad al momento de la cirugía fue de 17,8 años. El principal motivo de consulta fue por desmedro estético que correspondió al 41,8% de los pacientes. Salvo en 1 paciente, en todo el resto se ocupó una sola barra. En nuestra serie hubo 12 pacientes que presentaron alguna complicación operatoria y 1 paciente fallecido. Hasta el cierre del seguimiento se retiraron 61 barras, 2 de ellas previo al período estipulado de tratamiento, por morbilidad. Hay 20 barras in situ y 4 pacientes de los cuales no se tiene registro por abandono de controles. Discusión El pectus excavatum es la más frecuente de las deformidades de la pared torácica, es 4 a 6 veces más frecuente en hombres que en mujeres. En general los pacientes son asintomáticos, aunque algunos pueden presentar síntomas cardiopulmonares. La reparación con cirugía mínimamente invasiva con técnica de Nuss aparece hoy en día como el gold standard de manejo. Conclusión El manejo de los pacientes con pectus excavatum en nuestra Institución se asemeja a lo reportado en la literatura internacional. Nuestros esfuerzos deben apuntar a disminuir la morbimortalidad asociada.


Aim To communicate the experience in the treatment of pectus excavatum in the National Institute of Thorax. Materials and Method: Descriptive study with follow-up. Data of variables of interest were collected through the review of clinical records. Patients operated between March 2007 and April 2018 were included. Results 86 patients operated with the Nuss technique were included in the period described. Of them, 74 male patients. The average age at the time of surgery was 17.8 years. The main reason for consultation was due to cosmetic detriment that corresponded to 41.8% of the patients. Except in 1 patient, in all the rest a single bar was occupied. In our series, there were 12 patients who presented some operative complication and 1 patient died. Up to the end of the follow-up, 61 bars were removed, 2 of them in non-scheduled surgery. There are 20 bars in situ and 4 patients of which there is no registration due to abandonment of controls. Discussion Pectus excavatum is the most frequent of the deformities of the chest wall, it is 4 to 6 times more frequent in men than in women. In general, patients are asymptomatic, although some may have cardiopulmonary symptoms. The repair with minimally invasive surgery with Nuss technique appears today as the goldstandard of management. Conclusion The management of patients with pectus excavatum in our Institution is similar to that reported in the international literature. Our efforts should aim to reduce the associated morbidity and mortality.

ABSTRACT

Abstract Introduction Bone anchored hearing aids (BAHA) represent a useful surgical option for patients with single sided deafness. Objectives To compare multiple techniques for BAHA implantation regarding postoperative complications, operative time, and duration between the surgery and the first use of the BAHA. Methods A retrospective study was conducted of all patients receiving implantation of a BAHA from August of 2008 to October of 2014. Data collected included: patient age, gender, side operated, abutment length, operative time, duration until first use of the BAHA, operative technique, and postoperative complications. The statistical analysis was performed using analysis of variance (ANOVA), Tukey pairwise comparison, chi-square, and paired t-test. Statistical significance was determined using a level of p< 0.05. Results A total of 88 patients (43 female and 45 male) were included in the data analysis. A total of 80 complications were documented, and these complications were classified according to the Holgers criteria. A significant difference in the total postoperative complications existed between the six techniques used (ANOVA; p< 0.01). In addition, there was also a significant difference among the six techniques employed regarding the operative time (ANOVA; p< 0.01). The average time duration until fitting of the BAHA processor among the various techniques trended toward but did not reach statistical significance (ANOVA; p= 0.16). Conclusions Significant differences in the operative outcomes exist among the various techniques for BAHA implantation. Based on the statistical analysis of our data, the BAHA Attract system (Cochlear Ltd., Sidney, Australia) requires greater operative time, but it is associated with less postoperative complications than percutaneous techniques and its processor may be fitted significantly sooner.

ABSTRACT

Resumo Objetivo: Relatar perfil clínico epidemiológico de pacientes que apresentaram o pico hipertensivo após o IVA e apontar possíveis fatores de risco associados. Métodos: Estudo retrospectivo, observacional e descritivo (revisão de prontuário de pacientes assistidos no IBOPC) de 2014 a 2016. Resultados: Foram analisados 40 pacientes com glaucoma submetidos à implante de válvula de Ahmed. O diagnóstico pré-operatório mais comum foi glaucoma secundário, sendo a indicação pós-transplante penetrante de córnea a mais frequente. 95% das cirurgias foi de implante de tubo isolado. 56% dos pacientes tinham cirurgia anti- glaucomatosa prévia. 46% necessitaram de procedimento cirúrgico posterior para manejo de complicações pós-operatórias, sendo que a mais frequente foi atalamia (9,7%). PIO média no pré-operatório = 28,6 ± 12.20mmHg, com uso de 3,41 medicações. Com 3 semanas a PIO média aumentou para 16mmHg, com uso de 0,42 medicações. Após 3 meses de cirurgia a PIO média estava em 16.5mmHg, com uso de 1,86 de medicações. Após 6 meses de seguimento a PIO média reduziu (16,4 ± 6.74mmHg), com 2,23 ± 1.45 medicações. A média da AV (Snellen) foi de 20/100p no pré-operatório e de 20/200 após 6° mês de cirurgia. Catorze pacientes preencheram os critérios para a FH, destes 6 obtiveram resolução da FH. Dos pacientes que desenvolveram a FH, 78,4% iniciaram a elevação da PIO entre a 2ª e 4ª semana de pós-operatório. Seis (14,6%) pacientes obtiveram sucesso cirúrgico completo, parcial em 36,6% e falência 31%. Conclusão: A fase hipertensiva pode ocorrer em parte dos pacientes após as semanas iniciais do procedimento cirúrgico. O conhecimento deste fenômeno, o preparo prévio do cirurgião, o acompanhamento regular do paciente e o controle da PIO com o uso de medicações são determinantes na resolução desta complicação.


Abstract Objective: To report the clinical epidemiological profile of patients who presented the hypertensive peak after VAT and to indicate possible associated risk factors. Methods: A retrospective, observational and descriptive study (review of medical records of patients assisted in the IBOPC) from 2014 to 2016. Results: We analyzed 40 patients with glaucoma submitted to Ahmed Glaucoma Valve implant. The most common preoperative diagnosis was secondary glaucoma, with the most frequent corneal penetrating post-transplant indication. 95% of the surgeries were of isolated tube implantation. 56% of patients had previous anti-glaucomatous surgery. 46% needed a posterior surgical procedure to manage postoperative complications, and the most frequent was atalamia (9.7%). IOP preoperatively = 28.6 ± 12.20mmHg, with use of 3.41 medications. At 3 weeks the mean IOP increased to 16mmHg, with use of 0.42 medications. After 3 months of surgery the mean IOP was 16.5mmHg, with use of 1.86 of medications. After 6 months of follow-up the mean IOP decreased (16.4 ± 6.74 mmHg), with 2.23 ± 1.45 medications. The mean of the AV (Snellen) was 20 / 100p in the preoperative period and 20/200 after the 6th month of surgery. Fourteen patients fulfilled the criteria for HP, of which 6 obtained HP resolution. Of the patients who developed HP, 78.4% started to elevate IOP between the 2nd and 4th postoperative week. Six (14.6%) patients had complete surgical success, partial in 36.6% and bankruptcy in 31%. Conclusion: The hypertensive phase may occur in part of the patients after the initial weeks of the surgical procedure. The knowledge of this phenomenon, the previous preparation of the surgeon, the regular monitoring of the patient and the control of IOP with the use of medications are determinant in the resolution of this complication.

ABSTRACT

Abstract Introduction: The bone-anchored hearing aid is an effective form of auditory rehabilitation. Due to the nature of the implant, the most common complications are skin related. A number of alternative surgical implantation techniques have been used to reduce the frequency and severity of skin complications, including the U-shaped graft and the linear incision. Objective: To assess skin complications and their association with surgical technique, quality of life, and audiological benefit in patients with bone-anchored hearing aids. Methods: This was a retrospective study conducted in a tertiary referral center in Bogotá, Colombia. Patients who had been fitted with a bone-anchored hearing aid implant (unilaterally or bilaterally) for at least 6 months were included in the study. The Holgers classification was used to classify skin complications (Grade 0 = none; Grade 1 = erythema; Grade 2 = erythema and discharge; Grade 3 = granulation tissue; and Grade 4 = inflammation/infection resulting in the removal of the abutment). The Glasgow Benefit Inventory questionnaire was used to determine quality of life, and the Abbreviated Profile of Hearing Aid Benefit questionnaire was used to determine the subjective audiological benefit. Results: A total of 37 patients were included in the study (30 with unilateral implants and 7 with bilateral implant). Of the 44 implants evaluated, 31 (70.3%) were associated with skin complications (7 [15.9%] Grade 1; 4 [9.1%] Grade 2; 15 [34.1%] Grade 3, 5 [11.4%] Grade 4). The U-shaped graft was statistically associated with major complications (Grades 3 and 4) compared with the linear incision technique (p = 0.045). No statistically significant differences were found between Abbreviated Profile of Hearing Aid Benefit scores and severity of complications. Similarly, no differences were found between Glasgow Benefit Inventory physical health questions and skin complications. Conclusion: Despite the high frequency, skin complications did not seem to affect quality of life or subjective audiological benefits of patients with bone-anchored hearing aids.


Resumo Introdução: A prótese auditiva óssea (BAHA, do inglês Bone-Anchored Hearing Aid) é uma forma eficaz de reabilitação auditiva. Devido à natureza do implante, as complicações mais comuns são relacionadas à pele. Várias técnicas opcionais de implantação cirúrgica têm sido usadas para reduzir a frequência e a gravidade das complicações cutâneas, inclusive o enxerto em forma de U e a incisão linear. Objetivo: Avaliar as complicações cutâneas e sua associação com a técnica cirúrgica, qualidade de vida e benefício audiológico em pacientes com BAHAs. Método: Estudo retrospectivo feito em um centro terciário de referência em Bogotá, Colômbia. Os pacientes que receberam um implante de BAHA (unilateral ou bilateralmente) durante pelo menos seis meses foram incluídos no estudo. A classificação de Holgers foi usada para classificar as complicações cutâneas (Grau 0 = nenhuma, Grau 1 = eritema, Grau 2 = eritema e secreção, Grau 3 = tecido de granulação e Grau 4 = inflamação/infecção, resultou na remoção da estrutura de apoio). O questionário Glasgow Benefit Inventory (GBI) foi usado para determinar a qualidade de vida e o questionário Abbreviated Profile of Hearing Aid Benefit (APHAB) foi usado para determinar o benefício audiológico subjetivo. Resultados: Foram incluídos 37 pacientes (30 com implantes unilaterais e sete com implantes bilaterais). Dos 44 implantes avaliados, 31 (70,3%) foram associados às complicações cutâneas (sete [15,9%] Grau 1; quatro [9,1%] Grau 2; 15 [34,1%] Grau 3 e cinco [11,4%] Grau 4). O enxerto em forma de U foi estatisticamente associado a complicações maiores (Graus 3 e 4) em comparação com a técnica de incisão linear (p = 0,045). Não foram encontradas diferenças estatisticamente significativas entre os escores APHAB e gravidade das complicações. Do mesmo modo, não foram encontradas diferenças entre as questões de saúde física pelo questionário GBI e complicações cutâneas. Conclusão: Apesar da alta frequência, as complicações cutâneas não parecem afetar a qualidade de vida ou os benefícios audiológicos subjetivos de pacientes com BAHAs.

ABSTRACT

ABSTRACT Purpose: To evaluate the long-term outcomes of Boston type I keratoprosthesis (B-Kpro) in the management of patients with ocular burn injuries. Methods: This prospective study included all patients with ocular burns who underwent B-Kpro implantation at a tertiary eye care center between February 2008 and November 2015. Twelve patients (12 eyes) were enrolled. The procedures performed for managing ocular injury were identified, and information on ocular history, surgical procedures performed, and postoperative outcomes was collected. The main outcome measures were visual acuity, prosthesis retention, postoperative complications, and required surgical procedures. Results: Twelve eyes from 12 patients met the inclusion criteria for B-Kpro implantation, including nine eyes with alkali burns and three eyes with thermal burns. A total of 13 B-Kpro devices were implanted in the 12 eyes. The mean follow-up period was 60.8 months (range, 13-91 months). Preoperative best-corrected visual acuity ranged from counting fingers to light perception. Postoperative best-corrected visual acuity was better than 20/200 in 83.3%, 66.6%, and 57.1% of patients at 12, 48, and 60 months, respectively. The initial keratoprosthesis was retained in 10 (83.3%) eyes and was successfully replaced in one eye. The major cause of worsening of initial visual acuity was advanced glaucoma (four of 12 eyes). Conclusion: The anatomical and functional results support the use of B-Kpro for managing bilateral limbal stem cell deficiency secondary to ocular burns. However, glaucoma should be carefully evaluated, as it is a continuous threat that may result in irreversible visual loss in this population.


RESUMO Objetivo: Avaliar os resultados em longo prazo do implante da ceratoprótese de Boston tipo 1 (B-Kpro) no tratamento de pacientes vítima de queimadura ocular. Métodos: Trata-se de um estudo prospectivo envolvendo todos os casos de implante de B-Kpro 1 para queimadura ocular em um centro de oftalmologia terciário durante o período de fevereiro/2008 e novembro/2015. Doze pacientes (doze olhos) foram incluídos no estudo. Os procedimentos realizados para o manejo da queimadura ocular foram identificados, e os dados foram coletados com relação à história oftalmológica do paciente, procedimentos cirúrgicos realizados, e resultados pós-operatórios. Os principais parâmetros avaliados foram acuidade visual, retenção da prótese, complicações pós-ope ratórias e intervenções cirúrgicas necessárias. Resultados: Doze pacientes preencheram os critérios de inclusão para implante da B-Kpro, incluindo 09 olhos vítimas de queimadura por álcali e 03 olhos pós queimadura térmica. Um total de 13 B-Kpro tipo 1 foram implantadas em 12 olhos de 12 pacientes. O tempo de seguimento médio foi de 60,8 meses (variando, 13-91 meses). Melhor acuidade visual corrigida pré-operatória variou de conta dedos à percepção luminosa. Melhor acuidade visual corrigida pós-operatória foi melhor que 20/200 em 83,3%, 66,6% e 57,1% dos pacientes em 12 meses, 48 meses e 60 meses, respectivamente. A ceratoprótese inicialmente implantada permaneceu retida em 10 (83,3%) dos olhos e foi re-implantada com sucesso em um olho. A principal causa de piora da acuidade visual inicialmente atingida foi glaucoma avançado (4 de 12 olhos). Conclusão: Os resultados anatômicos e funcionais reportados neste estudo dão suporte ao uso da B-Kpro para o tratamento da deficiência límbica bilateral secundária a queimadura ocular. Glaucoma é o principal fator limitante e pode causar perda visual irreversível nesses pacientes.

ABSTRACT

ABSTRACT Objective To validate the application of the bacterial cellulose (BC) membrane as a protecting barrier to the urethra. Materials and Methods Forty female Wistar rats (four groups of 10): Group 1 (sham), the urethra was dissected as in previous groups and nothing applied around; Group 2, received a 0.7cm strip of the BC applied around the urethra just below the bladder neck; Group 3, received a silicon strip with the same dimensions as in group 2; Group 4, had a combination of 2 and 3 groups being the silicon strip applied over the cellulosic material. Half of the animals in each group were killed at 4 and 8 months. Bladder and urethra were fixed in formalin for histological analysis. Results Inflammatory infiltrates were more intense at 4 months at lymphonodes (80% Grade 2), statistically different in the group 2 compared with groups 1 (p=0.0044) and 3 (p=0.0154). At 8 months, all samples were classified as grade 1 indicating a less intense inflammatory reaction in all groups. In group 2, at 8 months, there was a reduction in epithelial thickness (30±1μm) when com-pared to groups 1 (p=0.0001) and 3 (p<0.0001). Angiogenesis was present in groups 2 and 4 and absent in group 3. In BC implant, at 4 and 8 months, it was significant when comparing groups 4 with 1 (p=0.0159). Conclusion BC membrane was well integrated to the urethral wall promoting tissue remodeling and strengthening based on morphometric and histological results and may be a future option to prevent urethral damage.

ABSTRACT

ABSTRACT This study aimed to retrospectively evaluate a cohort of patients with prostate cancer and persistent urinary incontinence after radical prostatectomy. From January 2004 to December 2015, eighty-six individuals were identified to have received an AUS implant, provided by a private nonprofit HMO operating in Belo Horizonte, Brazil. On total, there were 91 AUS implants, with a median interval between radical prostatectomy and AUS implant of 3.6 years (IQR 1.9 to 5.5). The rate of AUS cumulative survival, after a median follow-up of 4.1 years (IQR 1.7-7.2 years), was 44% (n=40). The median survival of AUS implants was 2.9 years (IQR 0.5-7.9 years). Thirty-seven AUS implants (40.7%) resulted in grade III surgical complications. There were 5 deaths at 2.1, 4.7, 5.7, 5.7 and 6.5 years of follow-up, but none due to causes directly associated to the AUS implant. Persistent severe incontinence was documented in 14 (15.3%) additional patients. From the 51 AUS implants which resulted in grade III surgical complications or persistent severe incontinence, 24 (47.1%) underwent surgical revisions. Explantation of the sphincter or its components was observed in 6 cases (25.0%). Mechanical failure, described as fluid loss and/or inability to recycle the AUS device, was observed in 4 devices (16.7%). In conclusion, although AUS implants are recommended as the gold-standard treatment of severe urinary incontinence after prostatectomy, the observed high rates of malfunction and grade III adverse events are a matter of concern warranting further assessment on the safety and efficacy of these devices.

ABSTRACT

Objective: The rupture of mammary protheses PIP (poly-implant-prothese) caused an alarm, settling in Spain a protocol for the management of patients. As hospital unit of reference for the management, monitoring and treatment of patients carrying PIP breast implants, we propose objective to make a descriptive study of the current situation in our country and compare it to the hitherto described in the literature. Method: We conducted a transversal study of all patients who came during the years 2012 and 2013, to the Unit of Mammary Pathology of the Universitary General Hospital of Elche. Results: With a total of 285 women, we observed a high rate of implant rupture (50.2 percent) asymptomatic most (84.6 percent). Fact that the year 2006 had the highest percentage of breakage and the appearance of siliconomas. Conclusions: Our series confirms rupture rate similar to that described in the literature for PIP breast implants. We observed a higher percentage of breakage from the year 2006, coinciding with the period of manufacture described poorer quality of these implants. Axillary siliconomas were evident in 35.1 percent of patients, the only locally axillary symptoms.


Objetivo: La rotura de las prótesis mamarias PIP (poly-implant-prothese) ha supuesto una alarma, estableciéndose en España un protocolo para el manejo y seguimiento de las pacientes. Como unidad hospitalaria de referencia para el manejo, seguimiento y tratamiento de las pacientes portadoras de prótesis mamarias PIP, nos proponemos como objetivo realizar un estudio descriptivo de la situación actual en nuestro medio y compararlo con lo hasta ahora descrito en la literatura. Método: Realizamos un estudio transversal de todas las pacientes que acudieron durante los años 2012 y 2013, a la Consulta de la Unidad de Patología Mamaria del Hospital General Universitario de Elche. Resultados: Con un total de 285 mujeres, observamos la elevada tasa de ruptura de los implantes (50,2 por ciento) la mayoría asintomáticos (84,6 por ciento). Siendo el año 2006 el de mayor porcentaje de rotura y la aparición de siliconomas. Conclusiones: Se confirma una tasa de ruptura similar a la descrita en la literatura para los implantes mamarios PIP. Observamos un mayor porcentaje de rotura a partir del año 2006, coincidiendo con el período de fabricación descrito de peor calidad de estos implantes. Se evidenciaron siliconomas axilares en el 35,1 por ciento de las pacientes, siendo la única sintomatología a nivel local axilar.

ABSTRACT

Objective This study aimed to compare the effectiveness and complications between the retropubic and transobturator approaches for the treatment of female stress urinary incontinence (SUI) by conducting a systematic review. Materials and Methods We selected all randomized controlled trials (RCTs) that compared retropubic and transobturator sling placements for treatment of SUI. We estimated pooled odds ratios and 95% confidence intervals for intraoperative and postoperative outcomes and complications. Results Six hundred twelve studies that compared retropubic and transobturator approaches to midurethral sling placement were identified, of which 16 were included in our research. Our study was based on results from 2646 women. We performed a subgroup analysis to compare outcomes and complications between the two approaches. The evidence to support the superior approach that leads to better objective/subjective cure rate was insufficient. The transobturator approach was associated with lower risks of bladder perforation (odds ratio (OR) 0.17, 95% confidence interval (CI) 0.09-0.32), retropubic/vaginal hematoma (OR 0.32, 95% CI 0.16-0.63), and long-term voiding dysfunction (OR 0.32, 95% CI 0.17-0.61). However, the risk of thigh/groin pain seemed higher in the transobturator group (OR 2.53, 95% CI 1.72-3.72). We found no statistically significant differences in the risks of other complications between the two approaches. Conclusions This meta-analysis shows analogical objective and subjective cure rates between the retropubic and transobturator approaches to midurethral sling placement. The transobturator approach was associated with lower risks of several complications. However, good-quality studies with long-term follow-ups are warranted for further research. .

ABSTRACT

FUNDAMENTO: Há uma paucidade de dados comparando o método percutâneo e o cirúrgico para tratamento da comunicação interatrial tipo ostium secundum. OBJETIVOS: Análise de segurança e eficácia comparando ambos os métodos tratamento em um hospital excelência com vínculo o Ministério de Saúde. MÉTODOS: Estudo observacional, prospectivo, não randomizado de duas coortes de crianças e adolescentes < 14 anos tratadas por meio do cateterismo intervencionista (grupo A) ou da cirurgia cardíaca convencional (grupo B). A coleta dos dados foi prospectiva no grupo A e retrospectiva no B. RESULTADOS: De abr/2009 a out/2011 foram alocados 75 pts no grupo A e entre jan/2006 e jan/2011foram tratados 105 pts no grupo B. A idade e o peso dos pacientes foram maiores no grupo B e o diâmetro da comunicação interatrial do tipo ostium secundum foi semelhante entre os grupos. Sucesso técnico foi observado em todos os procedimentos e não houve óbitos. Complicações (a maioria menores) foram encontradas em 68% no grupo B e em 4% do grupo A (p < 0,001). As taxas de fluxo residual não significativo ou de oclusão total do defeito foram semelhantes nos dois grupos. A mediana de internação foi de 1,2 dias após o procedimento percutâneo e 8,4 dias após a correção cirúrgica (p < 0,001). CONCLUSÃO: Ambos os tratamentos são seguros e eficazes com ótimos desfechos, porém o tratamento percutâneo apresenta menor morbidade e tempo de internação. Tais observações embasam a visão que essa forma de tratamento deve ser, hoje em dia, o método de escolha para pacientes selecionados com CIA do tipo ostium secundum.


BACKGROUND: There is a scarcity of data comparing percutaneous and surgical closure of the secundum atrial septal defect (ASD). OBJECTIVES: Assessment of safety and efficacy of both methods of treatment in a referral center affiliated with the Ministry of Health. METHODS: Observational, prospective, non-randomized study of two cohorts of children and adolescents younger than 14 years, treated by catheterization or surgery. Data was collected prospectively in the percutaneous group (A) and retrospectively in the surgical group (B). RESULTS: A total of 75 patients (pts) were enrolled in group A from April 2009 to October 2011 and 105 pts were treated in group B from January 2006 to January 2011. Age was older and weight was higher in group B and the ASD diameter was similar in both groups. Technical success was achieved in all procedures and there were no deaths. Complications (most minor) occurred in 68% of group B and 4% of A (p < 0.001). Rates of total occlusion or non-significant residual shunts were similar in both groups. Median hospitalization time was 1.2 days in group A and 8.4 days in group B (p < 0.001). CONCLUSION: Both treatment modalities are safe and effective, showing excellent outcomes. However, the percutaneous treatment has lower morbidity and shorter in-hospital stay length. These observations support the concept that percutaneous treatment of atrial septal defects should be regarded as the method of choice to manage selected patients with this condition.

ABSTRACT

O cross-linking corneano é um procedimento usado para a estabilização mecânica e aumento da rigidez corneana em pacientes com ceratocone (reduzindo a possibilidade de progressão), e também em processos inflamatórios de afinamento corneano. Os segmentos de anéis corneanos intraestromais têm como princípio o aplanamento central da córnea. Inicialmente utilizados para correção de baixa miopia, a principal indicação atual é em pacientes com ceratocone, para melhorar a acuidade visual não corrigida, a acuidade visual corrigida e permitir uma melhor tolerância ao uso de lentes de contato como também retardar a necessidade de um transplante de córnea. O objetivo deste artigo é revisar algumas publicações relacionadas ao cross-linking corneano e à inserção do segmento de anel intraestromal, apresentando suas indicações, resultados e complicações relatadas até o momento.


Corneal cross-linking is a procedure used for stabilizing the cornea in patients with progressive keratoconus by increasing corneal rigidity, and it is also used in corneal inflammatory melting process. The intrastromal corneal ring segments act by flatting the center of the cornea. Originally designed for the correction of mild myopia, the segments are now being used for reduction of keratoconus in order to improve the uncorrected visual acuity, the best spectacle corrected visual acuity, to allow good tolerance to the use of contact lenses and delay the need for corneal grafting procedures. The present text presents a review of corneal cross-linking and insertion of intrastromal corneal ring segments, emphasizing their indications, results and complications related until now.

ABSTRACT

Purpose: To evaluate the results and extrusion rates of the Ahmed glaucoma valve (AGV) implantation through a needle-generated scleral tunnel, without a tube-covering patch, in children. Materials and Methods: A retrospective review of the charts of 106 Mexican children implanted with 128 AGVs operated between 1994 and 2002, with the needle track technique, at our institution, with at least six months follow up was done. Main outcome measures were intraocular pressure (IOP) control, tube extrusions or exposure and other complications. Results: Kaplan-Meier analysis demonstrated a 96.9% survival rate at six months, 82.4% at one year, 78.7% at two years, 70% at three years and 41.6% at four years. Total success at the last follow-up (IOP between 6 and 21 mm Hg without medications) was achieved in 30 eyes (23.5%), 58 eyes (45.3%) had qualified success (only topical hypotensive drugs) and 40 eyes (31.3%) were failures. The mean pre- and post-operative IOP at the last follow up was 28.4 mmHg (SD 9.3) and 14.5 mmHg (SD 6.3), respectively. No tube extrusions or exposures were observed. Tube-related complications included five retractions, a lens touch and a transitory endothelial touch. The risk of failure increased if the eye had any complication or previous glaucoma surgeries. Conclusion: Medium-term IOP control in Mexican children with glaucoma can be achieved with AGV implantation using a needle-generated tunnel, without constructing a scleral flap or using a patch to cover the tube. There were no tube extrusions, nor any tube exposures with this technique.

ABSTRACT

Total laryngectomy is potentially a debilitative surgery resulting in compromise of some of the most basic functions of life including speech and swallowing. This may have a profound adverse effect on the patient's physical, functional, and emotional health, and may result in a decreased quality of life (QOL). Until the 1980s, total laryngectomy was regarded as a dreadful, but often, life-saving procedure for which there was little alternative, and was used as a last resort. At that time survival at any cost in terms of QOL was paramount and many laryngectomies were forced into an isolated life as a mute and dysphasic recluse. Most attempts at voice restoration produced inconsistent results and often techniques were laborious, expensive, and ineffective, particularly when carried out as a salvage procedure after failed radiotherapy. Progress in voice rehabilitation, following total laryngectomy, over the last 30 years, has made an enormous difference in the whole concept of the management of laryngeal cancers. Currently there are several options available for these patients, namely, esophageal speech, artificial larynx, and tracheoesophageal speech. The choice of speech rehabilitation varies from patient to patient, but tracheoesophageal voice has become the preferred method. This article provides a brief account of surgical voice restoration after total laryngectomy. Special emphasis has been given to the surgical technique, special considerations, complications, and the prevention / treatment of tracheoesophageal voice restoration.

ABSTRACT

FUNDAMENTO: A eficácia dos stents farmacológicos em reduzir os índices de eventos cardíacos não é uniforme a todos os subgrupos de lesões ou pacientes. OBJETIVO: Avaliar a evolução clínica tardia dos pacientes submetidos a implante de stents farmacológicos nas lesões ateroscleróticas da artéria descendente anterior e identificar, entre as características clínicas, angiográficas e do ultra-som intravascular, quais as que permitem predizer risco de eventos cardíacos. MÉTODOS: De maio de 2002 a agosto de 2005, foram tratados 205 pacientes com implante de 236 stents farmacológicos guiados pelo ultra-som intravascular. RESULTADOS: Com um acompanhamento médio de 711 dias, a taxa de trombose do stent foi de 0,48 por cento, a mesma observada para infarto agudo do miocárdio ou cirurgia de revascularização. A taxa de revascularização da lesão tratada foi de 7,31 por cento e a taxa global de eventos de 10,24 por cento. Os indicadores de eventos, conforme análise multivariada, foram o implante de mais de um stent na mesma artéria, lesões concêntricas e área mínima intra-stent medida pelo ultra-som intravascular menor que 3,88 mm². CONCLUSÃO: Baseados nos dados obtidos, concluímos que a revascularização da artéria descendente anterior com implante de stents farmacológicos escolhidos e otimizados pelo ultra-som intravascular apresenta baixo índice de eventos tardios. O implante de dois stents farmacológicos para o tratamento das lesões longas foi o principal fator independente para a ocorrência de eventos tardios. A área luminal final maior que 3,88 mm² obtidos nos segmentos de pequenos diâmetros de referência é um indicador independente de evolução livre de eventos.


BACKGROUND: The efficacy of pharmacological stents in decreasing the incidence of cardiac events is not homogeneous for all lesions or patient subgroups. OBJECTIVE: 1) To evaluate the late clinical evolution of patients submitted to pharmacological stent implantation in atherosclerotic lesions of the left anterior descending artery; 2) to identify, among the clinical, angiographic and intravascular ultrasonographic characteristics, the ones predictive of cardiac event risk. METHODS: From May 2002 to August 2005, 205 patients were treated with 236 pharmacological stent implants, guided by the intravascular US (IVUS). RESULTS: After a mean follow-up period of 711 days, the rate of stent thrombosis was 0.48 percent, the same observed for acute myocardial infarction or revascularization surgery. The revascularization rate of the treated lesion was 7.31 percent and the general event rate was 10.24 percent. The event indicators, according to the multivariate analysis were the implant of more than one stent in the same artery, concentric lesions and the minimal intra-stent area measured by IVUS < 3.88 mm². CONCLUSION: Based on the data obtained, we conclude that the revascularization of the left anterior descending artery with pharmacological stent implant, chosen and optimized by IVUS, presents a low incidence of late events. The implant of two pharmacological stents for the treatment of long lesions was the main independent factor for the occurrence of late events. The final luminal area > 3.88 mm² obtained in the small reference-diameter segments is an independent indicator of event-free evolution.

CONCLUSIÓN: Tomando como base los datos obtenidos con esta investigación, concluimos que la revascularización de la arteria descendente anterior con implante de stents farmacológicos, elegidos y optimizados por el ultrasonido intravascular, presenta un bajo índice de eventos tardíos. El implante de dos stents farmacológicos para el tratamiento de las lesiones largas fue el principal factor independiente para la ocurrencia de eventos tardíos.

ABSTRACT

Repeated implantation of pacemaker in the same patient is a common occurrence because of the increased longevity of patients. However, repeated lead fracture in the same patient and migration of the pacemaker lead into the pulmonary circulation is rare. We describe a 56-year-old gentleman who had undergone pacemaker implantations thrice due to repeated lead fractures (thrice) and also had migration of the pacemaker lead into the pulmonary circulation. He also had an azygous vein which was noticed while placing the temporary pacemaker wire.

ABSTRACT

To evaluate the potential utility of a self-expandable intratracheal nitinol stent with flared ends for the treatment of tracheal collapse in dogs, endotracheal stenting therapy was performed under fluoroscopic guidance in four dogs with severe tracheal collapse. During the 4 to 7 month followup, after stent implantation, clinical signs, including dyspnea and respiratory distress, dramatically improved in all dogs. The radiographs showed that the implanted stents improved the tracheal collapse, and there were no side effects such as collapse, shortening or migration of the stents. In conclusion, the self-expandable intratracheal nitinol stents provided adequate stability to the trachea and were effective for attenuating the clinical signs associated with severe tracheal collapse.

ABSTRACT

OBJETIVO: Avaliar os efeitos do implante de anel corneano intra-estromal sobre a curvatura da córnea em coelhos. MÉTODOS: Trinta olhos de 15 coelhos foram divididos em 2 grupos: o primeiro com 7 e o segundo com 8 animais. O olho esquerdo foi operado e o direito serviu de controle nos 2 grupos. Paquimetria ultra-sônica e ceratoscopia computadorizada foram realizadas no pré-operatório; biomicroscopia de segmento anterior e ceratoscopia computadorizada, no pós-operatório. No grupo 1, foi realizado implante de dois segmentos de anel. No grupo 2, os segmentos foram implantados separadamente. Compararam-se os achados topográficos do pré e do pós-operatório por meio de alterações quantitativas e qualitativas em 4 quadrantes. RESULTADOS: A análise quantitativa no pré-operatório não demonstrou diferença significativa entre os grupos. No grupo experimento 1, houve abaulamento corneano nos setores nasal (p=0,02) e temporal (p=0,04), na comparação com o grupo controle 1. No grupo experimento 2, observou-se o mesmo fato (p=0,02 nasal e temporal) quando comparado ao grupo controle 2. Após implante do segundo segmento, observou-se aplanamento significativo nos setores superior e inferior e abaulamento nos setores nasal e temporal (p=0,02 para todos os quadrantes). Pela análise qualitativa, observou-se astigmatismo uniforme nos grupos controle 1 e 2. No grupo experimento 1, observou-se astigmatismo simétrico contra a regra. No grupo experimento 2, observou-se astigmatismo contra a regra assimétrico, após implante do primeiro segmento, e simétrico, após o segundo implante. CONCLUSÃO: Observou-se aplanamento corneano significativo no eixo onde se localizam as extremidades do segmento de anel e abaulamento nos setores onde se localiza seu corpo. O implante de apenas um segmento induz astigmatismo assimétrico.


PURPOSE: To evaluate the effect of intrastromal corneal ring implantation on corneal curvature in rabbits. METHODS: Thirty eyes of 15 rabbits were divided into two groups: group 1 with 7 animals and group 2 with 8 animals. The left eye underwent surgery and the right eye was used as control. Ultrasound pachymetry and corneal topography were performed prior to surgery. Anterior segment biomicroscopy and corneal topography were performed after surgery. In group 1, implantation of two ring segments was performed. In group 2, ring segments were implanted separately. Topographical findings, before and after surgery, were compared through quantitative and qualitative alterations and divided into four quadrants. RESULTS: Quantitative analysis showed no significant difference between the groups in the preoperative period. Experiment group 1 showed nasal (p=0.02) and temporal (p=0.04) corneal steepening, compared to control group 1. Experiment group 2 showed nasal and temporal corneal steepening and superior and inferior corneal flattening (p=0.02 for all quadrants) compared to the control group 2. Qualitative analysis showed uniform astigmatism in both control groups. In experiment group 1, against-the-rule regular symmetrical astigmatism was observed after surgery. In experiment group 2, against-the-rule regular asymmetrical astigmatism was found after implantation of the first ring segment, and against the rule regular symmetrical astigmatism was observed after implantation of the second segment. CONCLUSION: In this study, significant corneal flattening occurred in quadrants where ring segments extremities were located and corneal steepening was observed in quadrants where its body was located. Implantation of one ring segment induces asymmetrical astigmatism.

ABSTRACT

Mechanical articulated device to replace intervertebral disc as a treatment for low back pain secondary to disc degeneration has emerged as a promising tool for selected patients. The potential advantages are prevention of adjacent segment degeneration, maintenance of mobility as well as avoidance of all the complications associated with fusion. The short-term results have been comparable to that of fusion, a few mid-term results have shown mixed outcome, but information on long-term results and performance are not available at present. The rationale for lumbar disc arthroplasty, indications, contraindications, the various artificial devices in the market and the concepts intrinsic to each of them, basic technique of insertion, complications are discussed and a brief summary of our experience with one of the devices is presented.

ABSTRACT

BACKGROUND: Subclavian vein puncture is commonly performed to insert the pacing lead for permanent pacemaker implantation. Our aim was to study the safety and feasibility of venogram-guided extrathoracic subclavian vein puncture for permanent pacemaker lead insertion. METHODS AND RESULTS: Sixty patients (32 males, and 28 females) underwent permanent pacemaker lead insertion by extrathoracic subclavian vein puncture at our institute between March 2002 and December 2002. Fifteen patients underwent dual-chamber and 45 single-chamber pacemaker implantation. All the patients underwent extrathoracic subclavian vein puncture guided by venogram, except 1 who underwent dual-chamber pacemaker implantation in whom the ventricular lead insertion was via the cephalic vein on an elective basis. The procedure was successful in all the patients. Inadvertent subclavian artery puncture occurred in 2 patients without any complication. There was no incidence of pneumothorax, hemothorax or pacemaker site infection. CONCLUSIONS: Venogram-guided extrathoracic subclavian vein puncture is safe and successful. It may be adopted as one of the preferred approaches for permanent pacemaker lead insertion.
