RESUMO

The use of root coverage procedures to treat gingival recession defects, a common periodontal condition, is an important aspect of periodontal regenerative therapy. The synergistic relationship between vascular configuration and involved tissues is the most important factor in soft tissue graft success. The present case reports the clinical effectiveness of Gingival Unit Graft (GUG) for the management of Miller's class III gingival recession.Clinical parameters like Probing depth, recession depth, keratinized tissue width and clinical attachment level were measured at baseline and postoperative 6 months. Percentage of defect coverage was evaluated at postoperative 6 months. Healing was uneventful and 3mm root coverage was observed with 1mm residual recession and increase in keratinized gingiva after 6 months follow up. Free soft tissue autografts such as gingival unit transfers can be used along with bio-adhesives such as cyanoacrylates for predictable results in the management of recession defects.

RESUMO

Resumen: Introducción: Debido a las actividades inherentes del personal del servicio activo de la Armada de México, son constantes las lesiones ligamentarias, en particular la lesión del ligamento cruzado anterior de la rodilla (LCA). Actualmente, contamos con diversas técnicas y recursos para su reparación. Objetivo: identificar los resultados clínicos obtenidos en reconstrucción de ligamento cruzado anterior en militares en el activo. Material y métodos: estudio observacional retrospectivo donde se compararon los resultados clínicos de reparación de ligamento cruzado anterior en militares en el activo con uso de aloinjerto y autoinjerto en 46 pacientes que cumplieron criterios de inclusión para el procedimiento quirúrgico del año 2017 al 2019 en el Centro Médico Naval. Se incluyeron 23 pacientes para cada rubro de reparación de ligamento cruzado anterior con injerto autólogo (patelar contralateral) e injerto heterólogo (ligamento cruzado anterior cadavérico). A todos los pacientes se les aplicaron las escalas IKDC y Lysholm, para la evaluación de resultados subjetivos de mejoría clínica a un seguimiento de dos años. Resultados: se reclutaron 46 pacientes que fueron sometidos a reconstrucción de ligamento cruzado anterior con aloinjerto o con autoinjerto. La media de edad por grupo fue: autólogo 35.6 años, heterólogo 35 años. Índice de masa corporal (IMC) promedio: autólogo 26.5, heterólogo 26.5. Sexo masculino en su totalidad. Se observó un mejor nivel de beneficio clínico en los pacientes con injerto heterólogo, tanto en evaluación por escala de IKDC (media 95.52 ± 1.85) como en escala de Lysholm (media 94.91 ± 1.62), en comparación con los injertos autólogos, IKDC (media 89.92 ± 2.55) y Lysholm (media 86.04 ± 5.58), con diferencia significativa (p = 0.0001) al comparar ambas técnicas de reconstrucción de ligamento cruzado anterior. Conclusión: Los resultados de nuestro estudio sugieren que se obtiene una superioridad de funcionalidad referida por los pacientes en los que se utilizó heteroinjerto.


Abstract: Introduction: Due to the inherent activities of the active duty personnel of the Mexican Navy, ligament injuries are constant, particularly the anterior cruciate ligament of the knee (ACL). Currently, we have various techniques and resources for its repair. Objective: identify the clinical results obtained in anterior cruciate ligament reconstruction in active military. Material and methods: retrospective observational study comparing clinical outcomes of anterior cruciate ligament repair in active military with the use of allograft and autograft in 23 patients who met inclusion criteria for the surgical procedure from 2017 to 2019 at the Naval Medical Center. 23 patients (46 in total) were considered for each category of anterior cruciate ligament repair with autologous graft (contralateral patellar) and heterologous graft (cadaveric anterior cruciate ligament). With an average age of autologous (35.6 years), heterologous (35 years). BMI average: autologous (26.5), heterologous (26.5). Male gender in its entirety. The IKDC and Lysholm scales were applied to all patients for the evolution of subjective results of clinical improvement in a 2-year follow-up; where a significant difference (p = 0.0001) could be observed when comparing both anterior cruciate ligament reconstruction techniques. Results: we included 46 patients who underwent anterior cruciate ligament reconstruction for indication of complete injury respectively by the Joint Surgery Service of the Naval Medical Center. A better level of clinical benefit was observed in patients with heterologous graft, both in evaluation by IKDC scale (median 95.52 ± 1.85) as in Lysholm scale (median 94.91 ± 1.62) compared to autologous grafts, IKDC (median 89.92 ± 2.55) and Lysholm (median 86.04 ± 5.58), with value of p = 0.0001 for both cases. Conclusions: The results our study suggests that a superiority of functionality is obtained as reported by patients in whom heterograft was used.

RESUMO

Abstract Objective The purpose of this meta-analysis is to compare ligament healing on autograft and allograft in anterior cruciate ligament (ACL) reconstruction. Methods The selection of appropriate studies was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We made a statistical analysis using a review manager. Electronic reports were searched using the PubMed, Medline, and Cochrane Library databases. The inclusion criteria were animal studies and cellular histology of both grafts as an outcome. Results The initial search revealed 412 potential articles. After duplicates were removed, 246 articles remained. Then, 14 articles were obtained and screened for relevance and eligibility. The relevant articles were searched manually, checking for eligibility and details in order not to miss included reports. Subsequently, 5 studies were included, with a total of 232 samples, reporting the biopsied results with quantitative histology of ligament healing between allograft and autograft. The biopsy samples in those studies were examined under light or electron microscope, to analyze the cellular distribution area and ligamentization stages in each group. Meta-analyses found significant difference between autograft and allograft (Heterogeneity, I2 = 89%; Mean Difference, 95% confidence interval [CI] =-34.92, -54.90, -14.93; p = 0.0006). There is also a significant difference on both graft in cellular count at over 24 weeks (Heterogeneity, I2 = 26%; Mean Difference, 95% CI = -14.59, -16.24, -12.94; p < 0.00001). Conclusion In the current meta-analysis, autograft shows a significant difference when compared to allograft, with more cellular accumulation and faster remodeling response on the ligamentization process being noticed in the former. However, a larger clinical trial will be needed to emphasize this literature's result.

RESUMO

Ong speculum is used in glaucoma surgeries such as trabeculectomy to expose the superior part of the globe. The large inferior blade pushes the inferior conjunctival fornix, due to which the eyeball rotates downwards. It has not been used in other anterior segment surgeries before. We used this speculum in simple limbal epithelial transplantation (SLET) and pterygium surgery to expose superior bulbar conjunctiva for harvesting limbal and conjunctival grafts, respectively. As the superior conjunctiva and sclera become exposed, it facilitates the steps of harvesting limbal biopsy and conjunctival graft in SLET and pterygium surgery. This eliminated the need for a superior rectus suture or an assistant who would keep the globe rotated downwards. Its position could also be maneuvered to adjust the site of exposure when dissecting the area of pannus in SLET. Thus, it makes the superior conjunctiva more accessible.

RESUMO

Introduction: Developmental dysplasia of the hip (DDH) is the cause of 2.6-9.1% of all total hip prostheses implanted at any age and constitutes a challenge in revision surgeries. Objective: To present a case of severe acetabular dysplasia managed by the Stoppa-type approach. The Case: We report a case of a 26-year-old male patient with DDH initially treated with total hip replacement and then diagnosed with aseptic loosening (Paprosky 3A). Using a modified Stoppa approach; acetabular augmentation and bone autograft attached with endopelvic reconstruction plates were performed. Two years after the procedure our patient is asymptomatic, has no restrictions on his daily living activities, and is very satisfied with the result. Conclusions: The Stoppa approach was very useful for the endopelvic reconstruction of the acetabular roof, so it may be an option to treat severe acetabular defects. Level of evidence: IV.

RESUMO

Abstract The posterolateral corner is critical to knee stability. Neglected injuries have a direct impact on the prognosis due to residual instability, chronic pain, deformities, and failure to repair other structures. Several techniques are used to reconstruct the posterolateral corner, often with autologous ischiotibial grafts or homologous grafts. An option little used for knee ligament reconstructions is the peroneus longus tendon graft. Although reported as a good alternative for anterior cruciate ligament reconstruction, we found no case using a peroneus longus tendon graft for posterolateral corner reconstruction. Here, we describe the case of a patient who underwent a non-anatomical reconstruction of the posterolateral corner using a peroneus longus tendon graft. The patient underwent surgical procedures for ligament reconstruction and correction of the deformity caused by a failed graft, but his knee remained unstable. During the preoperative planning, it was decided to reconstruct the posterolateral corner with an ipsilateral peroneus longus tendon graft. Studies have shown that the peroneus longus tendon graft does not increase ankle morbidity, and that its length and diameter favor ligament reconstruction. Thus, the present article highlights the importance of the proper diagnosis of ligament injuries in the acute phase, and describes a new technique for posterolateral corner reconstruction that must be included in the surgeon's body of knowledge, increasing the amount of technical options.


Resumo O canto posterolateral tem grande importância na estabilidade do joelho. Sua lesão pode ser negligenciada, o que tem um impacto direto no prognóstico e resulta em instabilidade residual, dor crônica, deformidades e falha do reparo de outras estruturas. Existem diversas técnicas de reconstrução do canto posterolateral e o uso de enxertos autólogos dos isquiotibiais ou homólogos são as mais comuns. Uma opção pouco utilizada para reconstruções ligamentares no joelho é o enxerto do tendão fibular longo. Apesar de descrito como boa opção na reconstrução do ligamento cruzado anterior, não foi encontrado nenhum caso de uso do enxerto do tendão fibular longo na reconstrução do canto posterolateral. Neste artigo, descrevemos o caso de um paciente submetido a reconstrução não anatômica do canto posterolateral com uso do enxerto do tendão fibular longo. O paciente foi submetido a procedimentos cirúrgicos para reconstrução ligamentar e correção de deformidade ocasionada pela falha do enxerto, mas manteve instabilidade ligamentar. No planejamento pré-operatório, optou-se pela reconstrução do canto posterolateral com enxerto do tendão fibular longo ipsilateral. Estudos evidenciaram que o enxerto do tendão fibular longo não provoca aumento de morbidadeem relação aotornozelo abordado, bem comoseapresenta com comprimento e diâmetro favoráveis à reconstrução ligamentar. Dessa forma, este artigo aponta para a importânciadodiagnóstico correto das lesões ligamentaresnafase aguda,e para uma nova técnica na reconstrução do canto posterolateral, que deve fazer parte do arsenal de conhecimentos do cirurgião, pois aumenta as opções de técnicas.

RESUMO

AIM:To analyze the efficacy of modified pterygium resection combined with conjunctival autograft transplantation(CAT)in the treatment of pterygium.METHODS: A total of 140 patients(154 eyes)with pterygium treated in the ophthalmology department of our hospital from January 2018 to January 2021 were selected and grouped according to random number table method. In the observation group, 70 cases(76 eyes)were treated with modified pterygium excision combined with CAT, and improved iris restorer was used during the operation. In the control group, 70 patients(78 eyes)were treated with conventional pterygium excision combined with CAT, during which traditional iris restorer was used. Follow up for 1a, the postoperative vision, subjective symptoms, conjunctival signs(conjunctival congestion and chemosis), corneal epithelial healing, postoperative complications and recurrence rate were compared between the two groups.RESULTS: Compared with pre-operation, vision of the two groups decreased significantly on 1, 3 and 5d after operation(P&#x0026;#x003C;0.05), while there was no statistically significant difference between the groups(P&#x0026;#x003E;0.05). Compared with 1d after operation, the scores on subjective symptoms, conjunctival hyperemia and edema in the two groups decreased significantly on 3, 5 and 14d after operation(P&#x0026;#x003C;0.05), and those scores of the observation group on 3, 5 and 14d after operation were significantly lower than those of control group(P&#x0026;#x003C;0.05).The corneal fluorescein staining(FL)scores of the observation group on 3, 5 and 14d after operation were significantly lower than those of the control group(P&#x0026;#x003C;0.05). The proportion of repair time of corneal epithelial defect ≤5d in the observation group was significantly higher than that in the control group(P&#x0026;#x003C;0.05). The incidence rates of conjunctival granuloma, symblepharon, and the recurrence rate in the observation group were significantly lower than those in the control group(P&#x0026;#x003C;0.05).CONCLUSION: Modified pterygium resection combined with CAT is effective in the treatment of pterygium, which can alleviate postoperative irritative symptoms, conjunctival congestion and edema, and it is more conducive to postoperative corneal epithelial reconstruction, reduction of postoperative complications and recurrence rate.

RESUMO

Resumen: Introducción: las fracturas de escafoides representan 50-80% de las fracturas de los huesos del carpo. De las fracturas de escafoides 10% evolucionan a no unión con tratamiento conservador y presentan cambios degenerativos en el carpo en 75-97% a cinco años y en 100% a 10 años. El objetivo de este trabajo fue evaluar la tasa y tiempo de consolidación en pacientes con diagnóstico de no unión de fractura de escafoides, sin fragmentación del polo proximal, tras tratamiento con dos tornillos canulados sin cabeza e injerto autólogo esponjoso de radio distal. Material y métodos: serie de casos de cuatro pacientes con diagnóstico de no unión de fractura de escafoides sin fragmentación del polo proximal, tratados mediante reducción abierta y fijación interna utilizando dos tornillos canulados sin cabeza y toma más aplicación de autoinjerto esponjoso de radio distal. Todos recibieron el mismo tratamiento postoperatorio y se tomó control radiográfico para evidenciar consolidación una vez que el paciente experimentó resolución clínica. Resultados: la tasa de consolidación radiográfica fue de 100% con un tiempo de consolidación promedio de 11.25 ± 3.4 semanas. No presentaron complicaciones y no fue necesaria una cirugía de revisión. Conclusión: el resultado del uso de dos tornillos canulados sin cabeza y toma más aplicación de autoinjerto óseo esponjoso de radio distal avala la técnica como una opción efectiva y segura para el tratamiento de no unión de fracturas de escafoides sin fragmentación del polo proximal.


Abstract: Introduction: scaphoid fractures comprise 50-80% of the fractures of the carpal bones. Ten percent of the scaphoid fractures evolve to non-union and show degenerative changes in the carpus in 75-97% at five years and in 100% at 10 years. The objective of this work was to evaluate the rate and time to union in patients with diagnosis of scaphoid non-union without fragmentation of the proximal pole after treatment with two cannulated headless screws and distal radius cancellous autograft. Material and methods: case series with short-term follow-up of four patients with scaphoid non-union without fragmentation of the proximal pole treated by internal fixation using two cannulated headless screws and distal radius cancellous bone autograft. All received the same postoperative treatment and radiographic control was taken as soon as the patient experienced clinical resolution. Results: the radiographic union rate was 100% with an average time to union of 11.25 ± 3.4 weeks. There were no complications and revision surgery was not necessary. Conclusion: the results of the use of two cannulated headless screws and distal radius cancellous bone autograft endorses the technique as an effective and safe option for the treatment of scaphoid non-union without fragmentation of the proximal pole.

RESUMO

Background:Numerous surgical procedures and changes have been ineffective in preventing the recurrence of pterygium. Aprospective clinical observational analysis of 205 individuals with primary pterygium was conducted where patients were treated with various surgical procedures. The patients were observed for two to five years in order to examine the frequency of recurrences and consequences. Result: Patients were divided into four groups and treated using a variety of surgical methods. Straightforward excision of pterygium was the treatment of choice in group 1. Excision with conjunctival rotation pedicle graft was used on patients in Group 2. Excision and conjunctival autograft were used to treat Group 3 patients. Patients in Group 4 received excision and a 0.02 percent solution of mitomycin c drops as a postoperative treatment. Age varied from 22 to 58, with a median of 34. All four groups had an equal number of men and women. Hemorrhage, astigmatism, symblepheron, foreign body feeling, and a corneo-scleral ulcer were among complications that were reported. There were 12 percent complications in group 1, 16 percent complications in group 2, 6 percent complications in group 3, and 8 percent complications in group 4. Criteria for recurrence was defined as the regrowth of fibrovascular tissue or the appearance of an aesthetic flaw. It's 30 percent for group 1; 14 percent for group 2, 9 per cent for group 3, and 8 per cent for group 4. Conclusion: The least rate of recurrence was noted in patients of Group 4 who had pterygium excision with postoperative mitomycin c instillation, and complications were least common in patients in Group 3 who had pterygium resection with conjunctival autograft

RESUMO

Objective:To evaluate the short-term outcomes of aortic root repair using a pericardial autograft for acute type A aortic dissection.Methods:Between January 2020 and August 2021, 12 patients underwent aortic root repair using a pericardial autograft for type A aortic dissection. There were 8 males and 4 females, aged from 32.0 to 71.0 years, with a mean of (49.1±13.0) years, weight from 40.0 to 100.0 with a mean of (78.6±20.5) kg. Short-term outcomes were assessed by cardiopulmonary bypass time, cross-clamp time, circulatory arrest time, mechanical ventilation time, ICU time, postoperative stay time. The diameter of Valsalva sinus and aortic regurgitation were assessed before, after operation and during follow-up.Results:There were no postoperative and follow-up death. Cardiopulmonary bypass time was(256.4±60.6)min, ranging from 182.0 to 243.0 minutes; cross-clamp time was(195.0±52.5)minutes, ranging from 127.0 to 284.0 minutes; circulatory arrest time was(19.9±3.6)min, ranging from 15.0 to 25.0 min; mechanical ventilation time was (69.1±72.1)hours, ranging from 6.4 to 250.3 h; ICU time was (143.6±81.7) h, ranging from 56.9 to 288.0 h; postoperative stay time was (12.8±4.1) days, ranging from 8.0 to 20.0 days. One patient had transient paralysis (8.3%), and one patient needed hemofiltration due to acute kidney failure (8.3%), they all completely recovered before discharge. Follow-up time ranged from 10.0 to 21.0 months, with a median of 13 months. Heart function (NYHA) was I to II degrees. The mean diameter of aortic root was (36.7±5.8)mm(27.0-45.0 mm) preoperatively, (35.8±5.1)mm (25.0-44.8 mm) before discharge, and (35.7±5.9)mm (25.1-44.8 mm) during follow-up, respectively. There was no significant difference between them ( P>0.05). The preoperative aortic regurgitation was as follow: severe aortic regurgitation 2, moderate 1, mild to moderate 3, mild 1, trivial 1, none 4; postoperative aortic regurgitation: mild 2, trivial 2, none 8; follow-up aortic regurgitation: mild 3, trivial 1, none 8. Conclusion:Aortic root repair with a pericardial autograft is a safe and effective technique to treat acute type A dissection involving the sinus. Using this technique, residual dissection tissues could be significantly reduced, which subsequently decreases the risk of proximal bleeding, maintains the function of sinus, and increases long-term durability. Short-term results are satisfactory, and the long-term results need further follow-up.

AIM: To compare the analysis of conjunctival autograft(CAG)or limbal conjunctival autograft(LCAG)for treating pterygium.METHODS: Systematic search of the National Library of America Medical Literature Search System(PubMed), the Excerpta Medica Database(EMBASE), the Cochrane Library and the US Clinical Trial Registry which all literatures established of the database from September 2021. The rate of recurrence, corneal epithelial healing time, the change in Schirmer Ⅰ test(SⅠt)and the change in tear break-up time(BUT)were analyzed. Statistical analysis was performed using Review Manager 5.3, count data were expressed as relative ratio(RR),measurement data were expressed as standardized mean difference(SMD)with 95%CI.RESULTS: There were 15 studies included with a total number of 1 883 surgical eyes,among them, there were 897 eyes experienced LCAG while 986 eyes underwent CAG. For the rate of recurrence, LCAG group was lower than CAG group(RR=0.33, 95%CI: 0.15-0.71, P=0.004). For corneal epithelial healing time, LCAG group seemed to behave better than CAG group(SMD=-0.87, 95%CI: -1.64 to -0.11, P = 0.02). No statistical significance was found for SⅠt(SMD = 0.03, 95% CI, -0.33-0.40, P=0.86)and as for BUT, LACG group showed longer times against CAG group(SMD=0.40, 95%CI: 0.09-0.70, P=0.01).CONCLUSIONS: Pterygium resection combined with LCAG was with lower recurrence rate, faster corneal epithelial healing and more stable tear film rather than CAG.

RESUMO

Introducción: La fractura de un hueso se define como la solución de continuidad de cierta porción ósea. Las fracturas diafisarias representan un bajo porcentaje de todas las fracturas, y el hueso tibial es el más afectado, debido a su escasa vascularidad, poca protección y existencia de diversos factores que hacen más propensos algunos problemas como pseudoartrosis y osteomielitis, que complican el tratamiento. Objetivo: Demostrar la eficacia de los resultados clínicos funcionales con la cura quirúrgica de pseudoartrosis infectada de diáfisis tibial con aporte de injerto óseo heterólogo de cadáver, y autoinjerto cortical esponjoso de cresta iliaca. Presentación del caso: Se presenta el caso de un paciente varón de 42 años que ingresa con diagnóstico de fractura expuesta II postraumática. Se realiza fijación externa en 2 ocasiones, con un intervalo de 6 días para corrección de valgo. El paciente se ausenta de sus controles clínicos y reingresa después de 10 meses aproximadamente por diagnóstico de pseudoartrosis atrófica infectada de tibia izquierda, según clasificación anatómica de Cierny-Mader IV. Se hospitaliza para cura quirúrgica y reconstrucción con aloinjerto óseo y autoinjerto de cresta iliaca, lo que da lugar a la consolidación y controles favorables. Actualmente el paciente ha recuperado la funcionalidad de su pierna izquierda, y queda como secuela una fístula con exposición de aloinjerto. Conclusiones: La cura quirúrgica de pseudoartrosis infectada de diáfisis tibial con aporte de injerto óseo heterólogo de cadáver, y autoinjerto cortical esponjoso de cresta iliaca presenta buenos resultados clínicos y funcionales, lo que constituye un método eficaz(AU)


Introduction: The fracture of a bone is defined as the solution of continuity of a certain bone portion. Diaphyseal fractures represent a low percentage of all fractures, and the tibial bone is the most affected, due to its scarce vascularity, little protection and the existence of various factors that make them more prone to some problems such as pseudoarthrosis and osteomyelitis, which complicate treatment. Objective: To demonstrate the efficacy of functional clinical results with the surgical cure of infected pseudoarthrosis of the tibial shaft with the contribution of heterologous cadaveric bone graft, and cortical cancellous autograft of the iliac crest. Case report: The case of a 42-year-old male patient admitted with a diagnosis of post-traumatic exposed fracture II is reported here. External fixation was performed on 2 occasions, with an interval of 6 days for valgus correction. The patient was absent from his clinical check-ups and was readmitted after approximately 10 months due to a diagnosis of infected atrophic nonunion of the left tibia, according to the anatomical classification of Cierny-Mader IV. He was hospitalized for surgical cure and reconstruction with bone allograft and iliac crest autograft, resulting in consolidation and favorable controls. Currently, the patient has recovered the functionality of his left leg, and a fistula with allograft exposure remains. Conclusions: Surgical treatment of infected tibial shaft pseudoarthrosis with provision of heterologous cadaveric bone graft and cortical cancellous autograft of iliac crest presents good clinical and functional results, which constitutes an effective method(AU)

RESUMO

Resumen: Introducción: Las alteraciones de la articulación patelofemoral son una de las causas más comunes de dolor e inflamación así como de daño articular e inestabilidad de la rodilla. La inestabilidad patelofemoral es una entidad común multifactorial que requiere de una realineación mediante técnicas proximales, distales o una combinación de ellas. Entre los procedimientos proximales en tejidos blandos se encuentra la plastía del ligamento patelofemoral medial (LPFM), la cual tiene como objetivo realinear la patela hacia medial y restaurar la anatomía entre el tendón cuadricipital, patela y tubérculo de la tibia. Objetivo: Demostrar que la plastía del LPFM con autoinjerto de cuádriceps es una técnica efectiva y con bajo nivel de complicaciones. Material y métodos: Estudio observacional, longitudinal, retrospectivo, descriptivo, básico y clínico. Se presenta una serie de 15 pacientes operados con esta técnica entre Octubre de 2014 y Septiembre de 2019. Resultados: La plastía del LPFM con autoinjerto del cuadricipital es una técnica segura que no utiliza implantes, lo cual reduce el riesgo de complicaciones y restaura la anatomía del aparato extensor de la rodilla. Conclusión: Nuestra técnica con autoinjerto de cuádriceps es segura, con buenos resultados a mediano plazo y baja incidencia de complicaciones. Los pacientes han regresado a sus actividades deportivas previas sin episodios de reluxación.


Abstract: Introduction: Alterations of the patellofemoral joint are one of the most common causes of pain and inflammation as well as joint damage and instability of the knee. Patellofemoral instability is a common multifactorial entity, requiring realignment by proximal, distal, or a combination of techniques. Within the proximal procedures in soft tissues, is the medial patellofemoral ligament plasty (MPFL), which aims to realign the patella medially and restore the anatomy between the quadricipital tendon, patella and tubercle of the tibia. Objective: To demonstrate that the plasty of the LPFM with quadriceps autograft is an effective technique with a low level of complications. Material and methods: Observational, longitudinal, retrospective, descriptive, basic and clinical study. We present a series of 15 patients operated with this technique between October 2014 and September 2019. Results: LPFM plasty with autograft quadricipital is a safe technique, which does not use implants, which reduces the risk of complications and restores the anatomy of the extensor apparatus of the knee. Conclusion: Our technique of repair of the medial patellofemoral ligament, with quadriceps autograft is a safe, reproducible technique, with good results in the medium term, as well as a low incidence of complications. Patients have returned to their previous sports activities without episodes of re-dislocation.

RESUMO

@#AIM: To analyze the influence of limbal conjunctival autograft and amniotic membrane transplantation on vision, corneal astigmatism(CAD)and tear film function in patients undergo pterygium surgery.<p>METHODS: Totally 96 patients(96 eyes)who had undergone pterygium surgery in the Department of Ophthalmology at Pengzhou People's Hospital were enrolled in this retrospective study between August 2018 and March 2020. According to random number table method, the patients were divided into observation group(48 patients with 48 eyes treated with pterygium excision combined with limbal conjunctival autograft)and control group(48 patients with 48 eyes treated with pterygium excision combined with amniotic membrane transplantation). General surgical indicators, uncorrected visual acuity(UCVA), tear film function \〖break-up time(BUT), SⅠt\〗, CAD, ocular surface disease index(OSDI), recurrence rate and incidence of complications were compared between the two groups.<p>RESULTS: The surgical time of observation group was longer than that of the control group, and the corneal epithelial healing time was shorter than that of the control group(<i>P</i><0.001). There was no significant difference in hospital stay or conjunctival hyperemia and edema remission time between the two groups(<i>P</i> >0.05). The UCVA of the two groups increased at 1, 3 and 6mo after surgery(<i>P</i><0.05), without statistically significant difference between groups(<i>P</i> >0.05). Compared with pre-operation, the BUT and SⅠt of both groups also increased, while CAD and OSDI scores decreased at 1, 3 and 6mo after surgery(<i>P</i><0.05). Besides, the BUT and SⅠt of observation group at 1mo after surgery were shorter/lower than control group, which were longer/higher than control group at 3 and 6mo after surgery(<i>P</i><0.05). However, there was no significant difference in CAD between the two groups(<i>P</i> >0.05). OSDI scores of the observation group were lower than those of the control group at 1, 3 and 6mo after surgery(<i>P</i><0.05). The recurrence rate of observation group within 6mo after surgery was lower than that of control group(<i>P</i><0.05), but the difference in incidence of complications was not significant(<i>P</i>>0.05).<p>CONCLUSION: Compared with amniotic membrane transplantation, limbal conjunctival autograft combined with pterygium excision applied in treatment of patients with pterygium can significantly shorten the corneal epithelial healing time, and reduce the influence on tear film function and recurrence rate, without affecting vision and corneal astigmatism. It is also safe and reliable.

RESUMO

OBJECTIVE@#To compare the clinical outcomes of arthroscopic anterior cruciate ligament (ACL) reconstruction (ACLR) with a tibialis anterior allograft (TAA)versus hamstring tendon autograft (HTA) after 10 years follow-up.@*METHODS@#A clinical data of 107 patients who underwent arthroscopic ACLR with a single bundle tendon between March 2007 and March 2010 was retrospectively analyzed. Among the patients, 48 patients were reconstructed with a tibialis anterior allograft (TAA group), including 26 males and 22 females, ranging in age from 16 to 38 years, with a mean of 27.2±6.2 years;59 patients were reconstructed with a hamstring tendon autograft (HTA group), including 31 males and 28 females, ranging in age from 16 to 40 years, with a mean of 28.0±7.6 years. The preoperative tibial anterior displacement and knee joint function, as well as knee joint stability, tibial anterior displacement and knee joint function at 10 years after operation were observed. Lachman test was used to evaluate the forward joint stability and pivot shift test to evaluate the rotational stability of the knee;KT-2000 side-to-side difference (SSD) was used to measure tibial anterior displacement;International Knee Documentation Committee(IKDC) score and Lysholm score were used to evaluate knee function.@*RESULTS@#The incisions of both groups were healed by first intention, and no early complications occurred after operation. All patients were followed-up 10 to 13 years, the mean time was 11.7 years. There was no graft failure were found during the follow up period. The KT-2000 SSD of the TAA group and the HTA group at ten years after operation were 1.9±0.7 and 1.8±0.6 respectively, which were significantly improved than 8.8±0.9 and 8.6±1.0 preoperatively(@*CONCLUSION@#The TAA and HTA have equal long term effect in ACL reconstruction, doctors and patients can choose the graft according to the actual situation.

RESUMO

@#AIM: To compare the effects of tear film after conjunctival autograft transplant(CAT)and limbal conjunctival autograft transplant(LCAT)for primary pterygium.<p>METHODS: In a prospective study, 150 patients(150 eyes)diagnosed with primary pterygium were collected in Beijing road medical area of Xinjiang Military Region General Hospital from September 2018 to May 2019. The 150 patients enrolled in the study in turn, and divided into two groups by the odd and even number. The odd number underwent CAT and the even number underwent LCAT. Respectively before surgery and 1, 3, 6mo and 1a after surgery, tear film break-up time(TBUT), SchirmerⅠtest(SⅠt)and ocular surface disease index(OSDI)were checked. The date were compared and analyzed.<p>RESULTS:Totally 129 patients(129 eyes)completed the follow-up of 1a, including 64 patients(64 eyes)from the CAT group and 65 patients(65 eyes)from the LCAT group. Four patients(4 eyes, recurrence rate 6.2%)in the CAT group and 3 patients(3 eyes, recurrence rate 4.6%)in the LCAT group developed recurrence. However, there was no significant in recurrence rate between CAT group and LCAT group(<i>P</i>=0.718). There were significant differences between before surgery and after surgery in each group(<i>P</i><0.05), and there were significant differences between 1mo after surgery and 3, 6mo and 1a after surgery in each group(<i>P</i><0.05), while there was no significant different among 3, 6mo and 1a after surgery in each group in TBUT, SⅠt and OSDI(<i>P</i>>0.05). Also there was no significant different between CAT group and LACT group in each time in TBUT, SⅠt and OSDI(<i>P</i>>0.05).<p>CONCLUSION:Both CAT and LCAT could effectively treat primary pterygium with low and similar recurrence rate, and the degree of improvement of tear film after primary pterygium operation is similar between the two surgical methods.

RESUMO

The present study aimed to evaluate the effects of mesenchymal stem cells derived from canine adipose tissue in the healing process of full-thickness mesh skin grafts in rabbits. The stem cells were collected from young dogs; and, after characterization, remained in cryopreservation, in independent doses containing 2 x 106 cells. The mesh distal limb graft technique was performed in 60 rabbits, divided into three groups, CG (Control Group), GT1 (Intralesional Stem Cell Treated Group), and GT2 (Intravenous Stem Cell Treated Group), containing 20 animals each. After grafting, each group was randomly divided into four subgroups according to euthanasia time 3, 7, 14, and 30 days, containing five animals in each group. Animals of GT1_14, GT1_30, and GT2_14, GT2_30 subgroups received a second dose of xenogeneic cells on the seventh day. Meanwhile, animals from GT1_30 and GT2_30 received the third dose of xenogeneic cells on day 14. The groups treated with xenogeneic stem cells positively affected type III collagen re-epithelialization and deposition, and possibly GT1 had a controlled inflammatory response. However, no effect on angiogenesis. Thus, it was possible to demonstrate tolerance and therapeutic action of mesenchymal stem cells from canine adipose tissue in skin grafts in rabbits.(AU)


O presente estudo teve como principal objetivo avaliar os efeitos das células-tronco mesenquimais derivadas do tecido adiposo de cães no processo de cicatrização de autoenxertos de pele de espessura total em malha em coelhos. As células-tronco foram coletadas de cães jovens, após a caracterização estas permaneceram em criopreservação, em doses individuais contendo 2 x 106 células. A técnica de enxerto em malha na região distal do membro foi realizada em 60 coelhos, divididos em três grupos, GC (Grupo Controle), GT1 (Grupo tratado com células-tronco intralesional) e GT2 (Grupo tratado com células-tronco via endovenosa), contendo 20 animais cada. Imediatamente após a enxertia, cada grupo foi dividido aleatoriamente em quatro subgrupos, de acordo com o tempo de eutanásia 3, 7, 14 e 30 dias contendo cinco animais cada. Animais dos subgrupos GT1_14, GT1_30 e GT2_14, GT2_30 receberam uma segunda dose de células xenógenas no sétimo dia. Ademais, animais do GT1_30 e do GT2_30 receberam a terceira dose de células xenógenas no dia 14. Os grupos tratados com células-tronco xenógenas tiveram um efeito positivo na reepitelização e deposição de colágeno tipo III, e possivelmente, o GT1 teve uma resposta inflamatória controlada, entretanto o efeito na angiogênese não foi observado. Dessa forma, foi possível demonstrar que houve tolerância e ação terapêutica das células-tronco mesenquimais derivadas do tecido adiposo de cães em enxertos de pele em coelhos.(AU)

RESUMO

RESUMEN: Comparar mediante una revisión sistemática los resultados clínicos de los procedimientos de cirugía plástica periodontal/periimplantar (CP) con injerto de tejido blando autógeno (ITB) obtenido del área lateral del paladar (ALP) versus del área de la tuberosidad (AT). Se realizó una búsqueda electrónica de ensayos clínicos en la base de datos Medline/Pubmed, Cochrane y las revistas de Periodoncia e Implantes de mayor impacto según la Web of Science, para hallar artículos publicados hasta abril del 2020. Se valoró el riesgo de sesgo de los artículos añadidos según el manual Cochrane Versión 5.1.0 para ensayos clínicos aleatorizados y la escala Newcastle-Ottawa para ensayos clínicos controlados. De una muestra inicial de 930 artículos, cuatro ensayos clínicos (tres aleatorizados) fueron incluidos en el presente estudio, donde se realizaron un total de 87 CP alrededor de piezas e implantes dentales, de las cuales 42 cirugías fueron realizadas con ITB del ALP y 45 cirugías con ITB del AT, se evaluó los resultados desde las 8 semanas hasta los 12 meses. No se hallaron diferencias estadísticamente significativas en los resultados clínicos entre ambos grupos, se mejoró el fenotipo gingival en la zona receptora para el grupo que obtuvo el ITB del AT y el nivel del dolor del sitio donador del AT fue menor en las dos primeras semanas que el sitio donante del ALP. Los estudios incluidos manifestaron un bajo riesgo de sesgo en promedio. Ambas áreas donantes de injerto de tejido blando proporcionan resultados clínicos similares, el injerto del área de la tuberosidad mejora el fenotipo gingival de la zona receptora y reduce el dolor post operatorio en las primeras semanas del sitio donador.


ABSTRACT: The objective of the study was to compare, through a systematic review, the clinical results of periodontal / peri-implant plastic surgery (CP) procedures with autogenous soft tissue graft (ITB) obtained from the lateral palate area (ALP) versus the tuberosity area (AT). We conducted an electronic search of clinical trials in the Medline/Pubmed, Cochrane database and the journals of Periodontics and Implants with the greatest impact according to the Web of Science, to find articles published until April 2020. The risk of bias of the articles added was assessed according to the Cochrane Manual Version 5.1.0 for randomized clinical trials and the Newcastle-Ottawa scale for controlled clinical trials. From the initial sample of 930 articles, four clinical trials were included (three randomized) in the present study, where a total of 87 PC were performed around dental pieces and implants, of which 42 surgeries were performed with ITB of the ALP and 45 surgeries with ITB of the AT, the results were evaluated from the 8 weeks to 12 months. No statistically significant differences were found in the clinical results between the two groups, the gingival phenotype in the receiving area was improved for the group that obtained the ITB of the AT and the level of pain at the donor site was lower in the first two weeks than the ALP donor site. The studies showed a lowrisk of bias on average. Both soft tissue graft donor areas provide similar clinical results, grafting the tuberosity area improves the gingival phenotype of the recipient area and reduces post-operative pain of the donor site in the first few weeks.
