ABSTRACT

La decanulación es el proceso de retirar la cánula de traqueotomía de forma definitiva, una vez que la patología original que motivó la traqueotomía se haya resuelto o mejorado significativamente.La predicción del éxito de decanulación es difícil debido a la influencia de varios factores. No existe un protocolo universalmente aceptado. Existen diversos protocolos y la elección depende, en gran medida, de cada institución y de la situación individual de cada paciente. Sin embargo, para lograr la decanulación exitosa deben tenerse en cuenta varios criterios esenciales que deben cumplirse independientemente del protocolo elegido.Se señalan las características que debe reunir el paciente apto para la decanulación y se presentan recomendaciones sobre los pasos necesarios para lograr el retiro de la cánula de traqueotomía en el niño de manera segura y minimizando el riesgo de fracaso.


Decannulation is the process of removing the tracheotomy cannula permanently, once the original pathology that led to the tracheotomy has been resolved or significantly improved. The prediction of decannulation success is difficult due to the influence of several factors. There is no universally accepted decannulation protocol. There are several protocols and the choice depends, largely, on each institution and the individual situation of each patient. However, in order to achieve successful decannulation, several essential criteria must be taken into account, which must be fulfilled regardless of the chosen protocol.We indicate the characteristics that the patient must meet for decannulation, and we present recommendations on the necessary steps to achieve the removal of the tracheotomy cannula in a child safely and minimizing the risk of failure.

ABSTRACT

ABSTRACT Purpose: To describe our experience in the management of retained encrusted ureteral stents using a single session combined endourological approach. Materials and Methods: Patients with retained encrusted ureteral stents who had been submitted to a single session combined endourological approach from June 2010 to June 2018 were prospectively evaluated. Patients were divided according to the Forgotten-Encrusted-Calcified (FECal) classification. The stone burden, surgical intervention, number of interventions until stone free status, operation time, hospital stay, complications, stone analysis, and stone-free rate were compared between groups. ANOVA was used to compare numerical variables, and the Mann-Whitney or Chi-square test to compare categorical variables between groups. Results: We evaluated 50 patients with a mean follow-up of 2.9±1.4 years (mean±SD). The groups were comparable in terms of age, sex, laterality, BMI, comorbidities, ASA, reason for stent passage, and indwelling time. The stone burden was higher for grades IV and V (p=0.027). Percutaneous nephrolithotomy was the most common procedure (p=0.004) for grades IV and V. The number of procedures until the patients were stone-free was 1.92±1.40, and the hospital stay (4.2±2.5 days), complications (22%), and stone analysis (66% calcium oxalate) were similar between groups. The stone-free rate was lower in grades III to V (60%, 54.5%, and 50%). Conclusions: The endoscopic combined approach in the supine position is a safe and feasible technique that allows removal of retained and encrusted stents in a single procedure. The FECal classification seems to be useful for surgical planning.

ABSTRACT

Abstract Objective The present study aims to identify the energy required for synthetic proximal femoral fracture after removal of three implant types: cannulated screws, dynamic hip screws (DHS), and proximal femoral nail (PFN). Methods Twenty-five synthetic proximal femur bones were used: 10 were kept intact as the control group (CG), 5 were submitted to the placement and removal of 3 cannulated screws in an inverted triangle configuration (CSG), 5 were submitted to the placement and removal of a dynamic compression screw (DHSG), and 5 were submitted to the placement and removal of a proximal femur nail (PFNG). All samples were biomechanically analyzed simulating a fall on the greater trochanter using a servo-hydraulic machine to determine the energy (in Joules [J]) required for fracture. Results All samples presented basicervical fractures. The energy required for fracture was 7.1 J, 6.6 J, 6 J, and 6.7 J for the CG, CSG, DHSG and PFNG, respectively. There was no statistically significant difference (considering a 95% confidence interval) in energy among the study groups (p = 0.34). Conclusion There was no statistically significant difference in the energy required to cause a synthetic proximal femoral fracture after removing all three implant types and simulating a fall over the greater trochanter.


Resumo Objetivo Identificar a energia necessária para ocorrência de fratura do fêmur proximal em osso sintético após retirada de três modelos de implantes: parafusos canulados, parafuso dinâmico do quadril (dynamic hip screw-DHS) e haste femoral proximal (proximal femoral nail-PFN). Métodos Foram utilizados 25 modelos de ossos sintéticos da extremidade proximal do fêmur: 10 unidades de grupo controle (GC), 5 unidades após colocação e retirada de 3 parafusos canulados colocados em configuração de triângulo invertido (GPC), 5 unidades após colocação e retirada do parafuso de compressão dinâmico (GDHS), e 5 unidades após colocação e retirada da haste de fêmur proximal (GPFN). Uma análise biomecânica foi realizada em todas as amostras simulando uma queda sobre o grande trocânter utilizando uma máquina servo-hidráulica com o objetivo de verificar a energia (em Joules [J]) necessária até a ocorrência de fratura nos diferentes grupos. Resultados Todos os grupos apresentaram fratura basocervical. Os grupos GC, GPC, GDHS e GPFN apresentaram, respectivamente, valores de 7.1J, 6.6J, 6J e 6.7J de energia até ocorrência da fratura. Não houve diferença estatisticamente significativa (intervalo de confiança de 95%) na energia entre os grupos de estudo (p = 0,34). Conclusão Não houve diferença estatisticamente significativa nos valores de energia necessária para ocorrência de fratura da extremidade proximal do fêmur após a retirada de três tipos de implantes utilizando modelos sintéticos simulando queda sobre o grande trocânter.

ABSTRACT

El soporte ventilatorio no invasivo es una herramienta que ha demostrado mejorar la sobrevida de pacientes con falla muscular de la bomba respiratoria y el manejo de enfermedades pulmonares crónicas, incluso la ventilación no invasiva nocturna ha servido de puente hacia el trasplante pulmonar. Se presenta el caso de una adolescente de 14 años con enfermedad pulmonar crónica hipoxémica severa y falla ventilatoria secundaria, que requirió ventilación prolongada y traqueostomía en espera de trasplante pulmonar. Luego de reevaluar indemnidad de la vía aérea fue decanulada a soporte ventilatorio no invasivo, con uso alternado de mascarilla nasal nocturna y pieza bucal diurna, permitiendo descanso muscular respiratorio eficiente, y mejoría de flujo de tos con técnicas de apilamiento de aire. Este plan permitió una decanulación segura y realizar soporte continuo ventilatorio no invasivo con un programa de rehabilitación cardiorrespiratorio. Generalmente, el soporte ventilatorio no invasivo se utiliza en trastornos primarios de la bomba respiratoria. En este caso, se indicó para enfermedad pulmonar crónica hipoxémica, mostrando claros beneficios con oxigenación adecuada, buen rendimiento cardiovascular con mejor tolerancia al ejercicio y entrenamiento en el escenario de preparación al trasplante pulmonar.


Noninvasive Ventilatory Support has demonstrated to improve survival of patients with ventilatory pump muscle failure and nocturnal noninvasive ventilation is useful in chronic lung disease, even bridging to lung transplant. We present a 14 years old girl with severe hypoxemic chronic lung disease and secondary ventilatory failure, who required continuous long-term ventilation and underwent a tracheostomy waiting for lung transplant. After reevaluated the airway patency the patient was decannulated to Noninvasive Ventilation Support, alternating nocturnal nasal mask with diurnal mouth piece in order to provide efficient respiratory muscle rest, made air stacking and improved cough flow. This plan allows safe decannulation to continuous Noninvasive Ventilatory Support tailoring a rehabilitation cardiorespiratory program. Usually, Noninvasive Ventilation Support is prescribed for primary respiratory pump muscles failure, but in this case, it was applied for a hypoxemic chronic lung disease. Clear benefits were observed leading to appropriate oxygenation, good cardiovascular performance with better tolerance to exercise for training in the preparatory scenario of a lung transplant.

ABSTRACT

Resumen Introducción: El cuerpo extraño rectal (CER) es un problema de difícil manejo para el cirujano general. La vía anal es la puerta de entrada más habitual seguido de la oral. La sospecha clínica es fundamental para el diagnóstico, pudiendo apoyarse de imágenes. El tratamiento es su extracción por vía transanal o por vía anterior. Objetivos: Caracterizar, describir y presentar el tratamiento de los pacientes con CER que consultaron en urgencia del Hospital el Pino (HEP) entre los años 2011 y 2016. Material y Método: Estudio serie de casos. Se realiza revisión de fichas clínicas de pacientes con CER en un periodo de 5 años en el Servicio de Urgencia del HEP. Se identificó a los pacientes tratados en box y a aquellos tratados en pabellón. Se caracterizó según variables demográficas, tratamiento, complicaciones y días de hospitalización. Resultados: Se identificaron 18 pacientes, 13 hombres y 5 mujeres de 45 años (± 36-51) y 34 años (± 23-64) respectivamente. En 1 de ellos fue posible extracción manual transanal en box sin anestesia y en 17 se requirió tratamiento en pabellón, donde 12 fue por vía transanal y 5 por abordaje abdominal. En ningún caso se identificó lesión intestinal. Evolución postoperatoria adecuada. Días de hospitalización promedio 1,8 días. Conclusión: Este es un problema infrecuente y de difícil manejo. Existe mayor frecuencia en hombres de edades media siendo la puerta de entrada la vía anal en todos los casos. En la mayoría se requirió extracción en pabellón bajo anestesia siendo el abordaje transanal el más utilizado y con buenos resultados.


Introduction: The rectal forcing body (RFB) is a problem which involves a difficult management for surgeons. Anal via is the most frequent entrance area, followed by the oral via. Clinical suspicion is fundamental for diagnosis and it is possible to support it using imaging. Treatment considers extraction through transanal or frontal via. Aim: To describe and present the treatment of patients with rectal foreing body in the Urgency Service of El Pino Hospital during years 2011 to 2016. Materials and Method: Case studies. Clinical records revision of patients with rectal foreing body in the Urgency Service of El Pino Hospital considering a 5-year period. Patients are identified as those treated in the box and in a surgical pavilion. Patients were classified according to demographic variables, received treatment, associated complications and hospitalization time. Results: 18 patients are identified, 13 men and 5 women, 45 (± 36-51) and 34 (± 23-64) years respectively. It was possible to manually extract via trans-anal at box, in one of these cases; 17 of them required treatment at surgical pavilion, where 12 were via trans-anal and 5 via abdominal. None of these cases had intestinal injury. Post-surgery evolution was adequate. Average hospitalization was 1.8 days. Conclusion: RFB is a non-frequent problem which requires high diagnose suspicious to be able to carry out proper treatments. It is more frequent in middle age men, with transanal input. In most cases, the extraction was done in surgical pavilion and required anesthesia and were done via trans anal with good results.

ABSTRACT

Tracheostomy in children is an extremely delicate procedure, which consists in the creation of a stoma between the trachea and the skin. Among the most frequent indications are neurological disorders, obstruction of the upper airway or prolonged mechanical ventilation. Pediatric versus adult airway differences should be considered during surgery. In the postoperative period, hemorrhage, pneumothorax, pneumomediatin can occur. In the late postoperative period, accidental decannulation, false pathway, infection of the tracheostomy, and later formation of periostomal or endotracheal granulomas may occur. The care of the tracheostomy in the clinical unit must be with trained personnel and the family environment must be prepared for home care. As long as the tracheostomy persists, control of the airway superior and inferior to the tracheostomy must be maintained by fiber optic. Patients with neurological compromise or cardiopulmonary damage have a lower decannulation rate and a longer hospital stay.


La traqueostomía en niños es un procedimiento extremadamente delicado, que consiste en la creación de un ostoma entre la tráquea y la piel. Entre las indicaciones más frecuentes se encuentran trastornos neurológicos, obstrucción de la vía aérea superior o ventilación mecánica prolongada. Consideraciones a las diferencias de la vía aérea pediátrica versus del adulto deben tenerse en cuenta durante la cirugía. En el postoperatorio se puede presentar hemorragia, neumotórax y neumomediastino. En el postoperatorio tardío puede ocurrir decanulación accidental, falsa vía, infección de la traqueostomía, y más tardíamente formación de granulomas periostomales o endotraqueales. El cuidado de la traqueostomía en la unidad clínica debe ser con personal capacitado y se debe preparar el entorno familiar para el cuidado en el domicilio. Mientras persista la traqueostomía se debe mantener control por fibra óptica de la vía aérea superior e inferior a la traqueostomía. Los pacientes con compromiso neurológico o daño cardiopulmonar tienen menor tasa de decanulación y mayor tiempo en el hospital.

ABSTRACT

Tracheostomy (TQT) in pediatrics is a procedure that allows maintaining permeable airways and establishes prolonged mechanical ventilation. Continuous noninvasive ventilatory support (CNVS) can always be used for patients capable of cooperating with it and mechanical insufflation-exsufflation (MIE). Despite this, TQT continues to be indicated frequently, limiting home transfer and care, conditioning additional burden of morbidity and risks. In those with upper airway obstruction (OVAS), except in <2 years, the decanulation follows similar guidelines as in adults. Small children who require even only sleep ventilation cannot be decannulated to NVS if they cannot be relied on to use it via noninvasive interfaces. So, children under age 12 should not be decannulated unless they are ventilator weaned. For adolescents and adults, the principle criterion for safe decannulation is an MIE-peak exsufflation flows (MIE-EF) over 150 L/m whereas need for tracheotomy occurs when MIE-EF decrease below 120 L/m, irrespective of extent of ventilator dependence. The following article is a critical narrative review of different decannulation alternatives to ensure that this process can be safely carried out with effectiveness and efficiency. Patients with different ages and diseases have been considered, knowing that younger children and adult in transition tracheostomized patients significantly increases the challenges.


La traqueotomía (TQT) permite mantener la vía aérea permeable y la ventilación mecánica prolongada. El soporte ventilatorio no invasivo continuo (SVNI) junto con la insuflación-exuflación mecánica (MIE), son una alternativa en la mayoría de los casos. Pese a esto, la TQT sigue indicándose frecuentemente, limitando la transferencia al hogar, condicionando carga adicional de morbilidad. En los niños con obstrucción de la vía aérea superior (OVAS), salvo en los <2 años, la decanulación sigue lineamientos similares que en adultos. Los <12 años dependientes de ventilador, aun cuando sólo sea nocturna, son decanulados o extubados a SVNI más difícilmente que adultos con dependencia continua. La mejor estrategia es evitar la TQT e indicar SVNI en los pacientes colaboradores que cumplan criterios. Excepto pacientes con estridor por OVAS grave o enfermedad de la primera motoneurona y severo compromiso miopático. Para adolescentes y adultos, el criterio para la decanulación segura es un pico flujo exuflado máximo en MIE (PFE-MIE), con o sin tos, >150 L/m, mientras que la necesidad de traqueostomía ocurre cuando el MIE (PFE-MIE) esta bajo 120 ml/min, independiente del grado de dependencia del ventilador. En menores de 12 años, el éxito del SVNI reside en obtener interfaces confiables para su entrega, de lo contrario no podrían ser decanulados. Siendo escasos los protocolos de decanulación pediátrica. Nuestro objetivo es el de ponderar alternativas seguras y eficientes para la decanulación de la TQT. Siendo considerados pacientes con edades y enfermedades distintas, sabiendo que los más pequeños, no colaboradores y dependientes de ventilación aumentan el desafío.

ABSTRACT

Abstract Introduction: Indications for cardiac devices have been increasing as well as the need for lead extractions as a result of infections, failed leads and device recalls. Powered laser sheaths, with a global trend towards the in-creasingly technological tools, meant to improve the procedure's outcome but have economic implications. Objective: The aim of this study is to demonstrate the experience of a Bra-zilian center that uses simple manual traction in most lead removals per-formed annually, questioning the real need for expensive and technically challenging new devices. Methods: This retrospective observational study included 35 patients who had a transvenous lead extraction in the period of a year between January 1998 and October 2014 at Hospital de Messejana Dr. Carlos Alberto Studart Gomes, in Fortaleza, CE, Brazil. Data were collected through a records review. They were evaluated based on age, type of device, dwelling time, indication for removal, technique used and immediate outcomes. Results: The median dwelling time of the devices was 46.22 months. Infec-tion, lead fracture and device malfunction were the most common indica-tions. Simple traction was the method of choice, used in 88.9% of the pro-cedures. Manual traction presented high success rates, resulting in com-plete removal without complications in 90% of the cases. Conclusion: This article suggests that lead extraction by simple manual traction can still be performed effectively in countries with economic diffi-culties as a first attempt, leaving auxiliary tools for a second attempt in case of failure or contraindications to the simple manual traction technique.

ABSTRACT

INTRODUCCIÓN: El uso prolongado de traqueostomía (TQT) conlleva a complicaciones que pueden minimizarse con una decanulación segura y temprana. La presión inspiratoria mantenida (PiMant) evalúa el comportamiento dinámico de la vía aérea en inspiración, la que puede relacionarse con la tolerancia a la oclusión de la TQT en pacientes en vía de decanulación. El OBJETIVO es el de describir la medición de PiMant y relacionar su valor con la tolerancia al uso de cánula tapada. METODOLOGÍA: Se evaluó la PiMant a 16 pacientes traqueostomizados, con vacuómetro anaeroide, registrando la moda de las presiones obtenidas, saturación de oxígeno, frecuencias respiratoria y cardíaca, uso de musculatura accesoria y estridor, a los minutos 1, 5, 10 y 15 de la oclusión de la TQT. RESULTADOS: mediana edad 60 meses, rango de presiones −2 a −40 cmH2O. Valores de PiMant > −7 cmH2O se asocian a mejor tolerancia al uso de cánula tapada. El estridor severo, asociado a aumento en frecuencia respiratoria, frecuencia cardiaca y uso de musculatura accesoria fueron los principales indicadores de fin de la prueba. CONCLUSIONES: PiMant es una prueba segura. PiMant> −7cmH2O, presentan mejor tolerancia a uso de cánula tapada.


INTRODUCTION: The prolonged use of tracheostomy leads to several complications, being necessary a prompt and safe decannulation. Maintained Inspiratory Airway Pressure (PiMant) is a functional evaluation of the dynamic changes of upper airway in inspiration which could indicate the tolerance to capped tracheostomy and adapting to this new airflow resistance, prior to decannulate. METHODS: Sixteen tracheostomized patients were evaluated with PiMant using a vacuum gauge, recording pressure value, oxygen saturation, respiratory rate, heart rate, accesory muscles use and presence of stridor during 15 minutes. RESULTS: Median age 60 months-old, pressure range −2 to −40 cmH2O. PiMant values > −7 cmH2O were associated with better tolerance to capped tracheostomy. Stridor was associated to increase of respiratory effort being the best criteria to bring to a halt the test. CONCLUSIONS: PiMant is a safe assessment, and indicates tolerance to capped tracheostomy when values > −7 cmH2O are found.

ABSTRACT

Abstract Introduction: The surgery during which the cochlear implant internal device is implanted is not entirely free of risks and may produce problems that will require revision surgeries. Objective: To verify the indications for cochlear implantation revision surgery for the cochlear implant internal device, its effectiveness and its correlation with certain variables related to language and hearing. Methods: A retrospective study of patients under 18 years submitted to cochlear implant surgery from 2004 to 2015 in a public hospital in Brazil. Data collected were: age at the time of implantation, gender, etiology of the hearing loss, audiological and oral language characteristics of each patient before and after cochlear implant surgery and any need for surgical revision and the reason for it. Results: Two hundred and sixty-five surgeries were performed in 236 patients. Eight patients received a bilateral cochlear implant and 10 patients required revision surgery. Thirty-two surgeries were necessary for these 10 children (1 bilateral cochlear implant), of which 21 were revision surgeries. In 2 children, cochlear implant removal was necessary, without reimplantation, one with cochlear malformation due to incomplete partition type I and another due to trauma. With respect to the cause for revision surgery, of the 8 children who were successfully reimplanted, four had cochlear calcification following meningitis, one followed trauma, one exhibited a facial nerve malformation, one experienced a failure of the cochlear implant internal device and one revision surgery was necessary because the electrode was twisted. Conclusion: The incidence of the cochlear implant revision surgery was 4.23%. The period following the revision surgeries revealed an improvement in the subject's hearing and language performance, indicating that these surgeries are valid in most cases.


Resumo Introdução: A cirurgia para a implantação do dispositivo interno do implante coclear não é inteiramente livre de riscos e pode apresentar problemas que exigem cirurgias revisionais. Objetivo: Verificar a incidência das indicações de cirurgias revisionais para a implantação do dispositivo interno do implante coclear, sua efetividade e correlacionar às variáveis relacionadas às categorias de linguagem e audição. Método: Estudo retrospectivo de pacientes menores de 18 anos submetidos à cirurgia de implante coclear de 2004 a 2015 em um hospital público no Brasil. Os dados coletados foram: idade no momento da implantação, sexo, etiologia da surdez, características audiológicas e da linguagem oral de cada paciente no pré e pós-operatório, necessidade de revisão cirúrgica e razão para ela. Resultados: Foram feitas 265 cirurgias em 236 pacientes. Oito pacientes foram submetidos ao implante coclear bilateral e 10 necessitaram de cirurgia de revisão. Foram necessárias 32 cirurgias para essas 10 crianças (um implante coclear bilateral), das quais 21 foram cirurgias de revisão. Em duas crianças, a remoção do implante coclear foi necessária, sem realização de reimplante; uma delas apresentava malformação coclear, por partição incompleta tipo I; e a outra, devido a trauma. Quanto à causa da necessidade da cirurgia revisional, das oito crianças que permaneceram com implante coclear, quatro apresentaram calcificação coclear após meningite, seguida de trauma (1), malformação do nervo facial (1), falha do dispositivo interno da IC (1) e torção do feixe de eletrodos (1). Conclusão: A incidência de cirurgias revisionais foi de 4,23%. O pós-operatório das cirurgias revisionais permite uma melhoria no desempenho de audição e na linguagem dos pacientes, indicando que essas cirurgias são válidas na maioria dos casos.

ABSTRACT

ABSTRACT A healthy 37 - year - old woman referred to our clinic with one - year history of recurrent urinary tract infection, dysuria and frequency. Her past medical history informed us that an IUD (Copper TCu380A) had been inserted 11 years ago. Eleven months after the IUD insertion she had become pregnant, unexpectedly. At that time, she had undergone gynecological examination and abdominal ultrasound study. However, the IUD had not been found, and the gynecologist had made the diagnosis of spontaneous fall out of the IUD. She had experienced normal pregnancy and caesarian section with no complications. On physical examination, pelvic examination was normal and no other abnormalities were noted. Urinalysis revealed microhematuria and pyuria. Urine culture was positive for Escherichia coli. Ultrasound study revealed a calculus of about 10 mm in the bladder with a hyperdense lesion. A plain abdominal radiograph was requested which showed a metallic foreign body in the pelvis. We failed to remove the IUD by cystoscopic forceps because it had strongly invaded into the uterine and bladder wall. Despite previous papers suggesting open or laparoscopic surgeries in this situation (1, 2), we performed a modified cystoscopic extraction technique. We made a superficial cut in the bladder mucosa and muscle with J - hook monopolar electrocautery and extracted it completely with gentle traction. This technique can decrease the indication of open or laparoscopic surgery for extraction of intravesical IUDs. In the other side of the coin, this technique may increase the risk of uterovesical fistula. Therefore, the depth of incision is important and the surgeon should cut the bladder wall superficially with caution. Although present study is a case report which is normally classified as with low level of evidence, it seems that our modified cystoscopic extraction technique is a safe and useful method for extraction of partially intravesical IUDs.

ABSTRACT

ABSTRACT Purpose: Retained or forgotten ureteral stents (FUS) have a potential to cause significant morbidity as well as medico-legal issues and increased cost. We aimed to evaluate the efficacy and usefulness of smartphone-based Ureteral Stent Tracker (UST) application and compare the results with basic appointment card system to prevent FUS, prospectively. Materials and Methods: A total of 90 patients who underwent ureteroscopic stone treatment procedure with indwelling DJ stents were equally distributed into two groups. In group-1, patients were followed using UST application. In group-2, only appointment cards were given to the patients. Two groups were compared in terms of stent overdue times and complete lost to follow up rates. Results: Forty-four patients in group-1 and 43 patients in group-2 completed the study. Among patients, 22.7% in group-1 and 27.9% in group-2 did not return for the stent removal on the scheduled day. In group-1, these patients were identified using the UST and called for the stent removal on the same day. After 6 weeks of maximal waiting period, mean overdue times in group-1 and group-2 were 3.5 days and 20 days, respectively (p = 0.001). In group-2, 3 patients (6.9%) were lost to follow up, while in group-1, it was none (p = 0.001). Conclusions: We found that the patients who were followed by the smartphone-based UST application has less overdue times and lost to follow up cases compared to the basic appointment card system. The UST application easily follows patients with indwelling ureteral stents and can identify patients when overdue.

ABSTRACT

BACKGROUND: The purpose of this study was to determine whether restoration of range of motion (ROM) could be achieved by implant removal after natural bone healing and consolidation of fractured vertebrae and examine whether early removal of the implant could maximize restoration of ROM. METHODS: This study included 30 cases of thoracolumbar fractures without neurological deficit requiring surgery (nine cases of flexion-distraction injuries and 21 cases of burst fractures). Percutaneous pedicle screw fixation (PPSF) was performed at the fractured vertebrae and one level above and one level below the fracture level. Pedicle screws were removed at an average of 12 months after surgery upon healing of fractured vertebrae. The following radiological and clinical findings were evaluated: restoration of anterior vertebral height ratio (AVHR), Cobb angle (CA), ROM, and complications. Sixteen patients who were checked for ROM were divided into two groups based on the time of implant removal: nine patients within 12 months and seven patients after 12 months. Restoration of vertebral height loss and ROM were compared between the two groups. RESULTS: At the final follow-up, significant pain relief and restoration of AVHR and CA were achieved in patients who underwent PPSF. Patients who had implant removed within 12 months after surgery had better ROM recovery than those who had implant removed after 12 months postoperatively. There were no significant differences in AVHR and CA between the two groups. CONCLUSIONS: PPSF followed by implant removal after healing of fractured body appears to be effective in achieving restoration of ROM. In our study, early removal of implant within 12 months after surgery was associated with better achievement of ROM than removal after 12 months. In addition, there were no significant differences in restoration of vertebral height between the two groups.

ABSTRACT

OBJECTIVE: The aim of this study was to present experiences in localization and removal of non-palpable subdermal contraceptive implants with ultrasonography. METHODS: Medical records from January 1, 2016, to April 30, 2018, were retrospectively reviewed for 21 patients who were referred to a single institution and had an impalpable implant despite following the removal instruction. In all the cases, more than one attempt was made to remove the implant before referral. The rod was detected using radiography and ultrasonography. In all the cases, localization of the single implant was achieved with ultrasonography. The distal depth of the rod was measured, and skin marking was made following the echogenicity. The implants were subsequently removed under anesthesia. RESULTS: In 18 cases, the rods were localized using ultrasonography and successfully removed under local anesthesia. In the other three cases, removal with local anesthesia failed. Although the rod was detected successful with ultrasonography, the implants were removed under general anesthesia in the operating room. The depth from skin to rod, measured with ultrasonography, was >12.0 mm in all the cases and located deep in the muscular layer in the failure cases. The depth of the implants positively correlated with the time spent for removal (r=0.525; P=0.015). CONCLUSION: High frequency ultrasonography is a highly accurate tool for localization and measurement of the skin-to-rod depth. It is also useful for removing non-palpable implants. If the depth of the implant is >12.0 mm, removal of the implant in the operating room under general anesthesia is recommended.

ABSTRACT

BACKGROUND: It is uncommon for patients who have received a permanent implant to remove the spinal cord stimulator (SCS) after discontinuation of medication in complex regional pain syndrome (CRPS) due to their completely painless state. This study evaluated CRPS patients who successfully removed their SCSs. METHODS: This 10-year retrospective study was performed on patients who had received the permanent implantation of an SCS and had removed it 6 months after discontinuation of stimulation, while halting all medications for neuropathic pain. Age, sex, duration of implantation, site and type of CRPS, and their return to work were compared between the removal and non-removal groups. RESULTS: Five (12.5%, M/F = 4/1) of 40 patients (M/F = 33/7) successfully removed the permanent implant. The mean age was younger in the removal group (27.2 ± 6.4 vs. 43.5 ± 10.7 years, P < 0.01). The mean duration of implantation in the removal group was 34.4 ± 18.2 months. Two of 15 patients (13.3%) and 3 of 25 patients (12%) who had upper and lower extremity pain, respectively, had removed the implant. The implants could be removed in 5 of 27 patients (18.5%) with CRPS type 1 (P < 0.01). All 5 patients (100%) who removed their SCS returned to work, while only 5 of 35 (14.3%) in the non-removal group did (P < 0.01). CONCLUSIONS: Even though this study had limited data, younger patients with CRPS type 1 could remove their SCSs within a 5-year period and return to work with complete pain relief.

ABSTRACT

ABSTRACT Background: The impact of central venous catheter (CVC) removal on the outcome of patients with candidemia is controversial, with studies reporting discrepant results depending on the time of CVC removal (early or any time during the course of candidemia). Objective: Evaluate the effect of time to CVC removal, early (within 48 h from the diagnosis of candidemia) vs. removal at any time during the course of candidemia, on the 30-day mortality. Methods: Retrospective cohort study of 285 patients with candidemia analyzing CVC removal within 48 h (first analysis) or at any time (second analysis). Results: A CVC was in place in 212 patients and was removed in 148 (69.8%), either early (88 patients, 41.5%) or late (60 patients, 28.3%). Overall, the median time to CVC removal was one day (range 1-28) but was six days (range 3-28) for those removed later. In the first analysis, APACHE II score (odds ratio [OR] 1.111, 95% confidence interval [95% CI] 1.066-1.158), removal at any time (OR 0.079, 95% CI 0.021-0.298) and Candida parapsilosis infection (OR 0.291, 95% CI 0.133-0.638) were predictors of 30-day mortality. Early removal was not significant. In the second analysis APACHE II score (OR 1.122, 95% CI 1.071-1.175) and C. parapsilosis infection (OR 0.247, 95% CI 0.103-0.590) retained significance. Conclusions: The impact of CVC removal is dependent on whether the optimal analysis strategy is deployed and should be taken into consideration in future analyses.
