RESUMO
INTRODUCTION: Acetabular revision surgery is a surgical challenge, especially when complex bone defects appear. This makes primary fixation and osseointegration of the implants difficult, which conditions the appearance of complications. Trabecular titanium implants attempt to solve these problems. OBJECTIVES: To evaluate our clinical-radiological results, the survival of the implants and the appearance of mid-term complications in acetabular revision surgery in a series of 37 acetabular replacements with Paprosky type IIIA and IIIB bone defects in which a trabecular titanium Cup-Cage revision implant was used. MATERIAL AND METHOD: We conducted an observational, descriptive and retrospective study of 37 cases with complex acetabular defects (20 type IIIA and 17 type IIIB, five of them with pelvic discontinuity) in which the acetabular component was replaced by trabecular titanium cups between 2011 and 2019. We analyzed clinical results (pain and functionality) and radiological parameters (restoration of the hip rotation centre and the mobilization of the implants), as well as the appearance of complications. RESULTS: The mean follow-up was 61 months. We obtained a median improvement of 8 points on the Merlé D'Aubigné-Postel functionality scale and 6 points on the VAS scale of pain perceived by the patient. We recorded two cases of acetabular loosening, one case of dislocation and three surgical wound infections without affecting the implant. CONCLUSIONS: The use of trabecular titanium Cup-Cage implants could be a valid option in acetabular revision surgery with complex acetabular defects, presenting good clinical and radiological results and in terms of complications and survival of the implants, mainly due to their good primary fixation and subsequent osseointegration.

Resumen: Introducción: las fracturas de acetábulo constituyen entre el 0.3 y 0.6% total de fracturas observadas, siendo estás lesiones relativamente infrecuentes. Objetivo: evaluar los resultados clínico-radiológicos del tratamiento quirúrgico mediante osteosíntesis de fracturas acetabulares con un seguimiento mínimo de 11.5 años. El objetivo secundario fue determinar la tasa de fracaso de la cadera de estos pacientes e identificar los factores de riesgo implicados. Materia y métodos: analizamos retrospectivamente una muestra de 23 pacientes intervenidos de fractura acetabular mediante reducción abierta y fijación interna, con un seguimiento medio de 14 años (11.5-17.5). Clasificamos las fracturas según Judet y Letournel en simples y complejas. Analizamos la evolución clínica y radiológica de estos pacientes mediante la escala de Harris. Resultados: obtuvimos una puntuación media de 81.90/100, objetivamos mejores resultados en fracturas de trazo simple respecto a fracturas complejas (p = 0.027). Evidenciamos mejores resultados clínicos en los pacientes con una reducción anatómica de la fractura (86.9/100), respecto a los que no fue posible (74.38/100) (p = 0.033). Fue necesaria la reintervención con artroplastía por mala evolución clínica en tres pacientes (13%). Como predictores de mal pronóstico para el desarrollo de coxartrosis identificamos las fracturas complejas y la reducción no anatómica de la fractura (p < 0.05). Encontramos relación entre índice de masa corporal (IMC) > 30 con peores resultados funcionales (p = 0.151). Conclusiones: el tratamiento quirúrgico de pacientes tratados con fracturas acetabulares presenta buenos resultados clínicos y radiológicos a largo plazo. Como factores de riesgo para la progresión de coxartrosis con suficiente impronta clínica como para ser necesaria una artroplastía identificamos, las fracturas complejas, la reducción no anatómica y un IMC > 30.
Abstract: Introduction: acetabular fractures constitute between 0.3 and 0.6% of all observed fractures, being these injuries relatively infrequent. Objective: to evaluate clinical and radiological outcomes of surgical treatment of patients with acetabular fracture treated in our hospital with a minimal follow-up of 11.5 years. The secondary objective is to determine the rate of failure in the hip joint of these patients and establish risk factors that are involved. Material and methods: 23 patients with acetabular fractures that were treated by open reduction and internal fixation (ORIF) were retrospectively analysed. They were follow-up during an average of 14 years (range 11.5-17.5). Fractures were classified by Judet y Letournel as simple or complex. Clinical and radiological outcomes were analysed by Harris scale. Results: We obtained an average of 81.90/100 on the Harris scale, aiming at better outcomes on simple fractures compare to those that were complex (p = 0.027). Higher scores were also achieved on those patients with an anatomical reduction (p = 0.033). Three patients required revision and placement of a total arthoplasty (13%). However, patients with body mass index (BMI) > 30 tend to achieve poor clinical results (p = 0.151). Conclusions: ORIF may be suggested for acetabular fractures since good clinical and radiological outcomes were recorded on a long-term follow-up. Complex fractures, non-anatomical reduction and BMI > 30 were identified as risk factors to coxarthrosis progression.
RESUMO
INTRODUCTION: The impact of the SARS-CoV-2 pandemic on healthcare has already been described, since it has caused an increase in diagnostic delay and morbidity. Our objective was to assess its influence on the development of complications in children with acute appendicitis. MATERIALS AND METHODS: A retrospective cohort study was carried out. It included acute appendicitis patients under 15 years of age treated from January 1, 2019 to December 31, 2020. They were classified according to diagnosis date as before the pandemic (B) (January 2019-February 2020) and during the pandemic (D) (March 2020-December 2020). According to operative findings, they were classified as complicated appendicitis (perforated/abscess/plastron/peritonitis) and non-complicated appendicitis (catarrhal/phlegmonous/gangrenous). Demographic data, progression time, and postoperative complications were analyzed. RESULTS: A total of 309 patients were included, 193 (62.5%) in Group B, and 116 (37.5%) in Group D, with an age of 9.2 ± 0.4 and 9.4 ± 0.6 years, respectively (CI = 95%). Diagnostic time was 1.35 and 1.43 days (p>0.05) in Groups B and D, respectively, with ≥ 3 days representing 15.5% of cases in Group B, and 16.4% of cases in Group D (p = 0.84). The proportion of complicated appendicitis was 23.3% in Group B vs. 21.6% in Group D (p>0.05). Postoperative complications were observed in 11.4% of patients in Group B, and in 13.8% of patients in Group D (p>0.05), with intra-abdominal abscess being the most frequent complication in both groups (54.5% of the total complications in Group B vs. 65.5% in Group D; p>0.05). CONCLUSIONS: The management of acute appendicitis and its complications in pediatric patients has not been impacted by the SARS-CoV-2 pandemic or the safety measures enforced.
INTRODUCCION: Se ha descrito el impacto de la pandemia del SARS-CoV-2 en la atención sanitaria, al suponer un aumento del retraso diagnóstico y morbilidad. Nuestro objetivo es evaluar su influencia en el desarrollo de complicaciones en las apendicitis agudas en niños. METODOLOGIA: Estudio retrospectivo de cohortes, incluyendo los pacientes menores de 15 años tratados por apendicitis aguda desde 01/01/2019 hasta 31/12/2020. Se distribuyeron según su fecha de diagnóstico en: antes de la pandemia (A) (enero/2019-febrero/2020) y durante la pandemia (P) (marzo-diciembre/2020). Según los hallazgos quirúrgicos se clasificaron en: apendicitis complicadas (perforadas/abscesos/plastrones/peritonitis) y no complicadas (catarrales/flemonosas/gangrenosas). Se analizaron datos demográficos, tiempo de evolución y complicaciones postoperatorias. RESULTADOS: Se incluyeron un total de 309 pacientes, 193 pacientes (62,5%) en el grupo A y 116 (37,5%) en el P, con edades de 9,2 ± 0,4 y 9,4 ± 0,6 años respectivamente (IC = 95%). Los días al diagnóstico fueron 1,35 y 1,43 (p>0,05) en A y P respectivamente, siendo ≥ 3 días en 15,5% de A y 16,4% en P (p = 0,84). La proporción de apendicitis complicada fue un 23,3% en A vs. 21,6% en P; con p>0,05. Se observaron complicaciones postoperatorias en 11,4% de A y 13,8% de P (p>0,05), siendo la más frecuente el absceso intraabdominal en ambos grupos (54,5% del total de complicaciones vs 65,5%; en A y P respectivamente; p>0,05). CONCLUSIONES: La atención sanitaria de la apendicitis aguda y sus complicaciones en pacientes pediátricos no se ha visto modificada por la pandemia del SARS-CoV-2 o las medidas de seguridad adoptadas durante la misma.

INTRODUCTION: The SARS-CoV-2 pandemic brought about a reduction in surgical activity. The objective of this work was to analyze its impact on inguinal hernia morbidity. MATERIAL AND METHODS: A retrospective study of cases and controls was carried out. Patients under 18 months of age undergoing inguinal hernia surgery from January 1, 2019 to August 31, 2020 were included. They were divided into two groups: patients undergoing surgery before (group A) or after (group D) the state of alarm was declared in Spain. Primary variables: episodes of incarceration and postoperative complications. Secondary variable: urgent or scheduled surgery. Demographic variables: sex, gestational age (GA), previous pathologies, age at diagnosis (AD), and age at surgery (AS) (months). RESULTS: 64 patients were included - 43 in group A and 21 in group D. In group A, median GA was 37+3, 90.5% of patients were male, median AD was 2.33, and median AS was 3.27. In group D, median GA was 31+2, 72.1% of patients were male, median AD was 3, and median AS was 3.63. There were no statistically significant differences. However, differences in terms of previous pathologies were significant (16.3% for Group A vs. 38.1% for group D) (p = 0.05). Regarding the primary variable, 25.6% of patients in group A had incarcerations vs. 33.3% of patients in group D (p = 0.51), whereas 9.3% of patients in group A had postoperative morbidity vs. 14.3% of patients in group D (p = 0.41). Regarding the secondary variable, 88.4% of surgeries in group A were scheduled vs. 90.5% of surgeries in group D (p = 0.583). CONCLUSION: In spite of reduced surgical activity, inguinal hernia morbidity did not surge in our environment. An increase in patients with previous pathologies was noted, which means severe patients should be prioritized.
INTRODUCCION: La pandemia del SARS-CoV-2 supuso una reducción de las jornadas quirúrgicas. Analizamos el efecto en la morbilidad de la hernia inguinal. MATERIAL Y METODOS: Estudio retrospectivo de casos y controles. Incluimos menores de 18 meses intervenidos de hernia inguinal desde 01/01/2019 hasta 31/08/2020, divididos en 2 grupos: intervenidos antes (grupo A) o después (grupo D) de la declaración del estado de alarma. Variables principales: episodios de incarceraciones y complicaciones postoperatorias. Variable secundaria: intervención urgente o programada. Variables poblacionales: sexo, edad gestacional (EG), patología previa, edad al diagnóstico(ED) y a la intervención (EI) (meses). RESULTADOS: Incluimos 64 pacientes, 43 grupo A y 21 grupo D. En el grupo A la mediana de EG fue 37+3, el 90,5% fueron varones, la mediana ED fue 2,33 y EI 3,27. En el grupo B la mediana de EG fue 31+2, el 72,1% fueron varones, la mediana ED fue 3 y EI 3,63. No hubo diferencias estadísticamente significativas. Si fueron significativas las diferencias en patología previa 16,3% A y 38,1% D (p = 0,05). Sobre la variable principal: 25,6% del A sufrieron incarceraciones frente a 33,3% del D (p = 0,51) y un 9,3% tuvieron morbilidad postoperatoria en A frente a 14,3% en D (p = 0,41). Respecto a la variable secundaria un 88,4% se realizaron de forma programada en el grupo A y un 90,5% en el grupo D (p = 0,583). CONCLUSION: Pese a la reducción de jornadas quirúrgicas no ha aumentado la morbilidad de la hernia inguinal en nuestro medio. Hemos observado un aumento de pacientes con patología previa, implicando la priorización de los pacientes más graves.

INTRODUCTION: Loss of bone stock and anatomical alteration of the proximal femur make femoral revision surgery a complex procedure in which the choice of implant will be critical. Our goal is to assess the clinical and radiological results of complete coating Monoblock stems. MATERIAL AND METHODS: Retrospective study of 78 consecutive cases of femoral review surgery intervened by our unit. RESULTS: The average follow-up was 122 months. The average score on the Harris Hip Score was 81.2 ± 11.4 points. An age of less than 65 years, a minor femoral defect according to Paprosky classification (I, II and IIIA), the existence of a single previous surgery and the non-occurrence of intra or postoperative complications, was associated with better clinical and functional outcomes (p < 0.05).Cumulative survival was 96.7% at age 10 if we consider as failure the removal of the stem by aseptic loosening and 92% if we consider withdrawal for any cause to fail. CONCLUSION: Despite the current tendency to use modularity in femoral review surgery and given the results presented, we consider that complete coating monoblock stems provide a firm and stable fixation. However, the worst results in patients with major defects have led to other options being considered.
INTRODUCCIÓN: La pérdida de stock óseo y la alteración anatómica del fémur proximal hacen de la cirugía de revisión femoral un procedimiento complejo en la que la elección del implante será fundamental. Nuestro objetivo es valorar los resultados clínicos y radiológicos de los vástagos monobloque de recubrimiento completo. MATERIAL Y MÉTODOS: Estudio retrospectivo de 78 casos consecutivos de cirugía de revisión femoral intervenidos por nuestra unidad. RESULTADOS: El seguimiento medio fue de 122 meses. La puntuación media en la escala de Harris Hip Score fue de 81.2 ± 11.4 puntos. Una edad menor de 65 años, un defecto femoral menor según la clasificación de Paprosky (I, II y IIIA), la existencia de una única cirugía previa y la no aparición de complicaciones intraoperatorias o postoperatorias se asoció con mejores resultados clínicos y funcionales (p < 0.05). La supervivencia acumulada fue de 96.7% a los 10 años si consideramos como fracaso la retirada del vástago por aflojamiento aséptico y de 92% si consideramos como fracaso la retirada por cualquier causa. CONCLUSIÓN: Pese a la tendencia actual al uso de la modularidad en cirugía de revisión femoral y dados los resultados presentados, consideramos que los vástagos monobloque de recubrimiento completo proporcionan una fijación firme y estable. Sin embargo, los peores resultados obtenidos en pacientes con defectos óseos mayores han provocado que se valore otro tipo de opciones.

BACKGROUND: Trans-olecranon fracture dislocations are the least frequent complex elbow instability. Proper surgical treatment should be performed to avoid postoperative complications. METHODS: A retrospective design study was performed. Patients that suffered from this injury, treated at our center from 2010 to 2016 were included. Fifteen patients were analyzed. Functional results were measured using DASH, MEPS and VAS scores. Average time from injury to first surgical treatment was 4.87 days. Radial head fracture was present in seven cases and coronoid process in three patients. Most frequent complication was hardware disturbances in five patients. Mean follow up was 3.65 years. RESULTS: Mean range of motion (ROM) was evaluated 1 year postoperatively: 129° flexion, 6° flexion contracture, and less than 5° deficit of pronation/supination. Clinical and functional results are encouraging, DASH 36.38, MEPS 100 and VAS 0.46. CONCLUSION: Trans-olecranon fracture dislocations could obtain functional range of movement, pain relief and good functional outcomes with a standardized protocol of surgical fixation. It is important to achieve proper ulnar fixation, focusing in reestablishing dorsal angulation, and also to treat radial head and coronoid injuries properly, if present.

BACKGROUND: The present study aimed to describe the evolution of hemodynamic parameters over time of patients with invasive placentation during their third trimester who were delivered via cesarean section and subsequently underwent obstetric hysterectomy under epidural anesthesia. METHODS: A prospective, descriptive, longitudinal, 11-month cohort study of 43 patients aged between 18 and 37 years who presented with invasive placentation. Minimal invasive monitoring was placed before the administration of epidural anesthesia for hemodynamic parameter tracking during the cesarean section. After delivery, the patients underwent an obstetric hysterectomy. Blood loss, hemodynamic parameters, and coagulation were managed via goal-directed therapy. Parameters were compared via repeated measures ANOVA and effect size estimation (Cohen's d). RESULTS: The mean age of the patients was 29.2 ± 3.4 years and was moderately overweight. They had minor cardiac index variance (P=NS, no significance), vascular systemic resistance index (NS), heart rate (P=NS), and median arterial pressure (P=NS). Differences were observed in the stroke volume index (P=0.015) due to moderately higher values (d = 0.3, P=0.016) in the middle of the surgery. Patients had lower cardiac index (d = -0.36, NS) and cardiac workload requirements (d = -0.29, P=0.034) toward the completion of surgery. CONCLUSION: Patients who are in their third trimester and who subsequently underwent obstetric hysterectomy under epidural anesthesia had modest surgical hemodynamic variance and reduced cardiac workload requirements toward the end of the surgery.
RESUMO
INTRODUCTION: The objective of this study is to assess the type, frequency and severity of complications after the implantation of the modular monopolar radial head prosthesis. MATERIAL AND METHODS: Forty-seven patients with 48 radial head prostheses implanted between 2009 and 2017 were reviewed retrospectively. Patients were evaluated clinical and radiographically for a mean follow-up of 43.55 months (range: 12-89). RESULTS: The same type of prosthesis was implanted in every patient (Ascension Modular Radial Head). The average score in the Mayo Elbow Performance Score was 88.29 ± 9.9 points. During the follow-up, three patients (6.25%) suffered from continuous pain. Twelve cases (25.5%) showed radiological oversizing, though only five were symptomatic. Heterotopic ossification was detected in twenty-seven cases (57.4%). Eleven patients (23.4%) developed postoperative stiffness. Nineteen cases (40.42%) showed periprosthetic osteolysis, from which seven were symptomatic. Thirteen patients (27%) developed surgery-related complications: three cases of infection, four cases of symptomatic loosening, two neurapraxies, one instability and three cases of oversizing with associated stiffness. Nine patients (18.75%) required reintervention. DISCUSSION: Our study obtains a 27% of overall complications, mostly related to oversizing and prosthetic loosening, and 19% of reinterventions. These results are similar to those presented in previous studies, with variations depending on the time of follow-up. Further research is also required to evaluate long-term results and the potential progression of the radiographic findings. CONCLUSION: Taken together, these data stress the need for improvement in both the surgical technique and the design of the implants.
INTRODUCCIÓN: El objetivo de este estudio es evaluar el tipo, la frecuencia y la gravedad de las complicaciones después de la implantación de la prótesis monopolar modular de cabeza radial. MATERIAL Y MÉTODOS: Se revisaron retrospectivamente 47 pacientes con 48 prótesis de cabeza radial implantadas entre 2009 y 2017 durante una media de 43.55 meses (rango: 12-89). RESULTADOS: Se implantó el mismo tipo de prótesis en cada paciente (Ascension Modular Radial Head). La puntuación media obtenida en la clasificación Mayo Elbow Performance Score fue de 88.29 ± 9.9 puntos. Durante el seguimiento tres pacientes (6.25%) sufrieron dolor continuo. Doce casos (25.5%) mostraron sobredimensión radiológica, aunque sólo cinco fueron sintomáticos. Se detectó osificación heterotópica en 27 casos (57.4%), 11 pacientes (23.4%) desarrollaron rigidez postoperatoria, 19 casos (40.42%) mostraron osteólisis periprotésica, de los cuales siete fueron sintomáticos, 13 pacientes (27%) presentaron complicaciones: tres casos de infección, cuatro casos de aflojamiento sintomático, dos neuroapraxias, una inestabilidad y tres casos de sobredimensionamiento con rigidez asociada. Nueve pacientes (18.75%) fueron reintervenidos. DISCUSIÓN: Presentamos 27% de complicaciones globales, principalmente relacionadas con la sobredimensión y el aflojamiento protésico y 19% de reintervenciones. Estos resultados son similares a los descritos en estudios previos con variaciones en función del tiempo de seguimiento. Asimismo, se requieren nuevos estudios para evaluar los resultados a largo plazo y la posible progresión de los hallazgos radiográficos. CONCLUSIÓN: En conjunto, estos datos ponen de manifiesto la necesidad de mejoría tanto de la técnica quirúrgica como del diseño de los implantes.

BACKGROUND: Terrible triad of elbow is a complex lesion with a high rate of complications. Our goal is to analyse both clinical results and complications after performing protocolised surgery. MATERIAL AND METHODS: The database of our hospital was used during 2005-2015, collecting characteristics of the patient, the fracture, the surgery and the associated complications, as well as functional results and range of mobility. RESULTS: A total of 62 triads were obtained, of which 27 (43%) were women and 35 (56%) were men. All had a Kaplan lateral approach and those who needed it were complemented with a medial approach to repair the LCM. The radial head was synthesized in 14 (22%) cases, a prosthesis was placed in 45 (74%) cases and other actions in 3 (5%) cases. Osteosynthesis of the choroid process was performed by transosseous harpoon±suture in 41 (62%) patients and by synthesis in 12 (19%) cases. In 9 (14%) cases, no action was taken. In 100% of the cases the LCL was repaired and in 9 (14%) the LCM also had to be repaired. Twenty-two percent of the patients required ESA due to instability after the surgical technique. With respect to results, a range of mobility was obtained between 120°/-20° of flexoextension and 98°/85° of pronosupination. In terms of complications, we obtained a total of 17 (27%). CONCLUSIONS: Elbow triads are complex lesions where protocolised surgery is necessary, nevertheless the complication rate was 27% in our series.

PURPOSE: Breast cancer patients receiving hormonal therapies face risks of relapse, increased rates of cardiovascular events, and toxicities of therapy such as aromatase inhibitor (AI)-associated musculoskeletal symptoms (AIMSS). C-reactive protein (CRP), a marker for inflammation, is associated with breast cancer outcomes. We evaluated whether the olive-derived polyphenol hydroxytyrosol combined with omega-3 fatty acids and curcumin would reduce CRP and musculoskeletal symptoms in breast cancer patients receiving adjuvant hormonal therapies. EXPERIMENTAL DESIGN: This prospective, multicenter, open-label, single arm, clinical trial enrolled post-menopausal breast cancer patients (n = 45) with elevated C-reactive protein (CRP) taking predominantly aromatase inhibitors to receive a combination of hydroxytyrosol, omega-3 fatty acids, and curcumin for 1 month. CRP, other inflammation-associated cytokines, and pain scores on the Brief Pain Inventory were measured before therapy, at the end of therapy and 1 month after completion of therapy. RESULTS: CRP levels declined during the therapy [from 8.2 ± 6.4 mg/L at baseline to 5.3 ± 3.2 mg/L (p = 0.014) at 30 days of treatment], and remained decreased during the additional 1 month off therapy. Subjects with the highest baseline CRP levels had the greatest decrease with the therapy. Pain scores also decreased during the therapy. There were no significant adverse events. CONCLUSIONS: The combination of hydroxytyrosol, omega-3 fatty acids, and curcumin reduced inflammation as indicated by a reduction in CRP and reduced pain in patients with aromatase-induced musculoskeletal symptoms. Longer studies comparing this combination to other anti-inflammatories in larger groups of patients with clinical outcome endpoints are warranted.

PURPOSE: To evaluate the prognostic factors associated with survival in patients treated with neoadjuvant treatment [chemoradiotherapy (CRT) or chemotherapy] followed by surgery (CRTS) in patients with stage IIIA-N2 non-small cell lung cancer (NSCLC). METHODS: A retrospective study was conducted of 118 patients diagnosed with stage T1-T3N2M0 NSCLC and treated with CRTS at 14 hospitals in Spain between January 2005 and December 2014. Overall survival (OS) and progression-free survival (PFS) were estimated using the Kaplan-Meier method and compared using the log-rank test. Cox regression analysis was performed. RESULTS: Surgery consisted of lobectomy (74.5% of cases), pneumectomy (17.8%), or bilobectomy (7.6%). Neoadjuvant treatment was CRT in 62 patients (52.5%) and chemotherapy alone in 56 patients (47.5%). Median follow-up was 42.5 months (5-128 months). 5-year OS and PFS were 51.1% and 49.4%, respectively. The following variables were independently associated with worse OS and PFS: pneumonectomy (vs. lobectomy); advanced pathologic T stage (pT3 vs. pT0-pT2); and presence of persistent N2 disease (vs. ypN0-1) in the surgical specimen. CONCLUSIONS: In this sample of patients with stage IIIA-N2 NSCLC treated with CRTS, 5-year survival (both OS and PFS) was approximately 50%. After CRTS, the patients with the best prognosis were those whose primary tumour and/or mediastinal nodal metastases were downstaged after induction therapy and those who underwent lobectomy. These findings provide further support for neoadjuvant therapy followed by surgery in selected patients.

BACKGROUND: Infection and instability are the complications of prosthetic shoulder surgery of more difficult management. Instability builds up to half of the cases, while the fungal infection accounts for less than 1% of all and can cause severe damage to bone and soft tissue. METHODS: In this case clinical fungal infection by Candida parapsilosis is presented in a shoulder hemiarthroplasty indicated by a fracture of the proximal humerus. He received surgical treatment in two-stages and administration of fluconazole for eight weeks prior to the second surgical time. In revision surgery was placed a reverse prosthesis as definitive treatment; however, the patient suffered several episodes of dislocation in the postoperative period; a second revision prosthetic surgery was necessary to use more stable components. During this surgery, we extracted samples that were analyzed, obtaining negative results for infection. RESULTS: Now after three years of follow-up, the patient is well, no limitations in their daily work and has a Constant Score of 50.5. DISCUSSION: We report our experience in this exceptional situation. We know, this is one of the first cases where the fungal infection and dislocation prosthetics in the same patient meet. This situation is a challenge for the surgeon, which has to treat complications two practically at the same time; we do not have scientific evidence to establish a criterion unified for the treatment of complications after surgery for revision of arthroplasty of the shoulder, especially in reverse or mega-denture prosthesis.
ANTECEDENTES: La infección e inestabilidad se encuentran entre las complicaciones de más difícil manejo en la cirugía protésica de hombro. La inestabilidad acumula hasta la mitad de los casos, mientras que la infección por hongos representa menos de 1% del total de infecciones y pueden causar daño severo a nivel óseo y de partes blandas. MÉTODOS: En este caso clínico se presenta una infección fúngica por Candida parapsilosis en una hemiartroplastía de hombro indicada por una fractura de húmero proximal. Se dio tratamiento quirúrgico en dos tiempos y administración de fluconazol durante ocho semanas previo al segundo tiempo quirúrgico. En la revisión se colocó una prótesis reversa como tratamiento definitivo; sin embargo, el paciente sufrió varios episodios de luxación en el postoperatorio. Fue necesaria una segunda cirugía de revisión protésica para sustituir por componentes de mayor estabilidad. Durante la misma, se extrajeron muestras que fueron analizadas, obteniéndose resultados negativos para infección. RESULTADOS: Actualmente tras tres años de seguimiento, el paciente se encuentra bien, sin limitaciones en su labor diaria y tiene un Constant Score de 50.5. DISCUSIÓN: Reportamos nuestra experiencia en esta situación excepcional. A nuestro conocer, éste es uno de los primeros casos en los que la infección fúngica y la luxación protésica coinciden en un mismo paciente. Esta situación es un reto para el cirujano, el cual tiene que tratar las dos complicaciones prácticamente a la vez. No se dispone de una evidencia científica para establecer un criterio unificado para el tratamiento de las complicaciones tras cirugía de revisión de artroplastía de hombro, especialmente en la prótesis reversa o megaprótesis.

The 18p tetrasomy is a structural chromosomal abnormality with the presence of an extra isochromosome 18p, caused by a nondisjunction failure during maternal meiosis II. This additional i(18p) occurs in 1 of 180,000 live-born children worldwide, affecting males and females equally. It is characterized by craniofacial dysmorphisms; ears, nose and throat (ENT) abnormalities; musculoskeletal alterations; and global development delay. We aim to present the clinical and cytogenetic findings of a 3-year-10-month-old Latin American male with i(18p), to support the gene dosage effects, comparing his features with the ones reported in literature. This patient was product of the second pregnancy of a 39-year-old woman and the first son of a 49-year-old man. His main clinical features were microcephaly, facial dysmorphism, generalized hypotonia, and developmental delay. A blood sample of the patient was required to perform a GTG-banded karyotype and a fluorescence in situ hybridization (FISH) for chromosome 18 short arm. In addition, an SNP microarray analysis was carried out to detect genomic imbalances. Cytogenetic analysis revealed the presence of a metacentric supernumerary marker chromosome. The FISH study confirmed the origin of the marker chromosome by showing two signals for the 18p subtelomere and an intermediate signal for the 18 centromere. The microarray analysis showed a copy number gain of 18,385 Mb within the 18p.Tetrasomy tends to be a result of de novo events. The presence of the patient's isochromosome could be explained by advanced maternal age as it is known that this factor has high influence in isochromosome formation. Despite that there were no genes associated with the i(18p)'s clinical manifestations, these features are negatively correlated with dosage effects of the entire short arm. Physical and language therapy was recommended to the patient; the family received medical orientation, and awareness in family planning was raised.
La tetrasomía 18p es una anormalidad cromosómica estructural con la presencia de un isocromosoma extra 18p, causado por una no disyunción durante la meiosis materna II. Este adicional i(18p) ocurre en 1 de 180.000 niños nacidos vivos en todo el mundo, y afecta a hombres y mujeres por igual. Se caracteriza por dismorfias craneofaciales; anomalías en oídos, nariz y garganta (ENT); alteraciones musculoesqueléticas y del desarrollo global. Nuestro objetivo es presentar los hallazgos clínicos y citogenéticos de un varón latinoamericano de 3 años y 10 meses de edad con i(18p), para explicar los efectos de dosificación génica, comparando sus características con las reportadas en la literatura. Este paciente es producto del segundo embarazo de una mujer de 39 años y el primer hijo de un hombre de 49 años. Sus principales características clínicas fueron microcefalia, dismorfia facial, hipotonía generalizada y retraso global en el desarrollo. Se requirió una muestra de sangre del paciente para realizar un cariotipo con bandas GTG y una hibridación fluorescente in situ (FISH) para el análisis del brazo corto del cromosoma 18. Además, se llevó a cabo un análisis de microarreglos para detectar desequilibrios genómicos. El análisis citogenético reveló la presencia de un cromosoma supernumerario metacéntrico. Mientras que el estudio FISH confirma el origen del cromosoma marcador al mostrar dos señales para subtelómeros 18p y una señal intermedia para el centrómero 18. El análisis de microarreglos mostró una ganancia en el número de copias de 18,385 Mb dentro de la región 18p.La tetrasomía tiende a ser el resultado de eventos de novo. El isocromosoma del paciente podría explicarse por la edad materna avanzada, ya que se sabe que tiene una gran influencia en su formación. A pesar de que no hay genes asociados con las manifestaciones clínicas de i(18p), estas características están negativamente correlacionadas con los efectos de dosificación de todo el brazo corto. Se le recomendó terapia física y de lenguaje al paciente, la familia recibió orientación médica y se concientiza sobre la planificación familiar.
RESUMO
OBJECTIVE: To evaluate the results of surgical treatment of intraarticular calcaneal fractures, and also to analyze the variables that influence the final clinical and radiological outcomes as well as the complications. MATERIAL AND METHODS: We retrospectively analyzed 86 intraarticular calcaneal fractures in 78 patients, who underwent surgery with an extended lateral approach and reconstruction plate. The mean age was 48 years (16-74 years) and the mean follow-up was 4.6 years (9-99 months); 54 patients (69.2%) suffered falls from less than 3m in height or banal injuries and 24 patients (30.8%) falls from more than 3m in height or high energy-accidents. According to the Sanders classification we operated 12 (15%) typeII, 54 (62.8%) typeIII and 20 (23.2%) typeIV fractures. RESULTS: The postoperative mean AOFAS score was 73.9 points, with good or excellent results in 57% of the patients. Twelve cases (14%) suffered surgical wound complications and 11 (12.8%) required subtalar arthrodesis. Significantly better results were obtained in the patients younger than 30 years old, patients that fell from less than 3m in height and patients with Sanders fractures types II and III compared to typeIV, which were associated with higher rate of subtalar arthrodesis. CONCLUSIONS: We consider that open reduction and internal fixation of intraarticular fractures of the calcaneus with reconstruction plate is a valid treatment alternative. Given the complications described and the secondary subtalar arthrodesis rate, we recommend a meticulous technique carried out by experienced surgeons.
RESUMO
OBJECTIVES: The role of surgery in stage IIIA-N2 non-small cell lung cancer (NSCLC) is an actively debated in oncology. To evaluate the value of surgery in this patient population, we conducted a multi-institutional retrospective study comparing neoadjuvant chemoradiotherapy or chemotherapy plus surgery (CRTS) to definitive chemoradiotherapy (dCRT). MATERIAL AND METHODS: A total of 247 patients with potentially resectable stage T1-T3N2M0 NSCLC treated with either CRTS or dCRT between January 2005 and December 2014 at 15 hospitals in Spain were identified. A centralized review was performed to ensure resectability. A propensity score matched analysis was carried out to balance patient and tumor characteristics (nâ¯=â¯78 per group). RESULTS: Of the 247 patients, 118 were treated with CRTS and 129 with dCRT. In the CRTS group, 62 patients (52.5%) received neoadjuvant CRT and 56 (47.4%) neoadjuvant chemotherapy. Surgery consisted of either lobectomy (97 patients; 82.2%) or pneumonectomy (21 patients; 17.8%). In the matched samples, median overall survival (OS; 56 vs 29 months, log-rank pâ¯=â¯.002) and progression-free survival (PFS; 46 vs 15 months, log-rank pâ¯<â¯0.001) were significantly higher in the CRTS group. This survival advantage for CRTS was maintained in the subset comparison between the lobectomy subgroup versus dCRT (OS: 57 vs 29 months, pâ¯<â¯0.001; PFS: 46 vs 15 months, pâ¯<â¯0.001), but not in the comparison between the pneumonectomy subgroup and dCRT. CONCLUSION: The findings reported here indicate that neoadjuvant chemotherapy or chemoradiotherapy followed by surgery (preferably lobectomy) yields better OS and PFS than definitive chemoradiotherapy in patients with resectable stage IIIA-N2 NSCLC.

OBJECTIVE: Herbert type B1 and B2 scaphoid fractures can be treated by orthopaedic treatment or surgery. The aim of this study is to analyse results and complications of scaphoid waist fractures treated using the percutaneous volar approach. MATERIAL AND METHOD: We present a retrospective study of 92 patients, treated in our institution from 2006 to 2016 using a volar percutaneous fixation. Mean Follow-up was 16 months (range 12-48). Injuries were classified using Hebert's classification, including B1 and B2 fracture types; the other fracture types following this classification system were excluded. Politrauma patients, dorsal approach, fractures associated with distal radius injuries, patients treated using another surgical technique and patients with non follow-up were also excluded. Functional results were evaluated using the DASH questionnaire. Consolidation was established as the presence of bony bridges crossing the fracture site on x-rays, associated with absence of pain. RESULTS: The average time to fracture healing was 6.6 weeks (range 5-11). After 12 months of follow-up, the average wrist range of motion was 70° of extension (range 58-75) and 70° of flexion (range 62-80). Regarding functional evaluation, the average DASH questionnaire score was 42. The most frequent complication was non-union in 4 cases (4.44%). Average surgical time was 25min. CONCLUSIONS: Volar percutaneous fixation is a simple and quick technique for a specialist surgeon, characterised by low morbidity and complication rates compared to ORIF and orthopaedic treatment, which accelerates the patient's functional recovery.
