Long-term functional outcomes and surgical retreatment after thulium laser enucleation of the prostate: A 10-year follow-up study

ABSTRACT Background: To evaluate the 10-year functional outcomes (primary) and frequency and predictors of BPH surgical retreatment (secondary) after ThuLEP. Materials and Methods: A single-center retrospective analysis of consecutive patients undergoing ThuLEP between 2010 and 2013 was performed. Inclusion criteria were: age ≥ 40 years, prostate volume (PV) ≥ 80 mL, International Prostate Symptom Score (IPSS)-Total score ≥ 8 points. IPSS-Total score was the primary outcome, and BPH surgical retreatment rate was the secondary outcome. Paired t-test, McNemar test, and Wilcoxon signed-rank test were used to compare variables. Logistic regression analysis was performed to evaluate predictors of surgical retreatment. Results: A total of 410 patients with a mean ±SD age of 63.9 ± 9.7 years and a PV of 115.6 ± 28.6 mL were included. Mean ±SD follow-up was 108.2 ± 29.6 months. IPSS-Total score was significantly improved at 1 year compared to baseline (23.3 ± 4.7 vs. 10.3 ± 3.8; p<0.001). It was similar after 5 years (10.5 ± 3.6 vs. 10.7 ± 5.0; p=0.161), with a significant worsening at 10 years (10.3 ±4.8 vs. 13.8 ±4.5; p=0.042) but remaining statistically and clinically better than baseline (13.8 ±4.5 vs. 22.1 ±4.3; p<0.001). After 10 years, 21 (5.9%) patients had undergone BPH reoperation. Baseline PV (adjusted OR 1.27, 95% CI 1.09-1.41; p<0.001) and time from BPH surgery (adjusted OR 1.32, 95% CI 1.15-1.43; p<0.001) were predictors of BPH surgical retreatment. Conclusions: ThuLEP is associated with optimal functional outcomes and a low frequency of BPH surgical retreatment in the long-term. Baseline PV and time from surgery were predictors of BPH reoperation.

Surgical treatment for severe pediatric tracheobronchomalacia: the 20-year experience of a single center

Abstract Objective: In children with tracheobronchomalacia, surgical management should be reserved for the most severe cases and be specific to the type and location of tracheobronchomalacia. The goal of this study is to describe the presentation and outcomes of children with severe tracheobronchomalacia undergoing surgery. Methods: Retrospective case series of 20 children operated for severe tracheobronchomalacia at a tertiary hospital from 2003 to 2023. Data were collected on symptoms age at diagnosis, associated comorbidities, previous surgery, age at surgery, operative approach, time of follow-up, and outcome. Surgical success was defined as symptom improvement. Results: The most frequent symptoms of severe tracheobronchomalacia were stridor (50 %), cyanosis (50 %), and recurrent respiratory infections (45 %). All patients had one or more underlying conditions, most commonly esophageal atresia (40 %) and prematurity (35 %). Bronchoscopy were performed in all patients. Based on etiology, patients underwent the following procedures: anterior aortopexy (n = 15/75 %), posterior tracheopexy (n = 4/20 %), and/or posterior descending aortopexy (n = 4/20 %). Three patients underwent anterior aortopexy and posterior tracheopexy procedures. After a median follow-up of 12 months, 16 patients (80 %) had improvement in respiratory symptoms. Decannulation was achieved in three (37.5 %) out of eight patients with previous tracheotomy. The presence of dying spells at diagnosis was associated with surgical failure. Conclusions: Isolated or combined surgical procedures improved respiratory symptoms in 80 % of children with severe tracheobronchomalacia. The choice of procedure should be individualized and guided by etiology: anterior aortopexy for anterior compression, posterior tracheopexy for membranous intrusion, and posterior descending aortopexy for left bronchus obstruction.

Introdução: A síntese de feridas de pele tensionadas é uma área que tem sido alvo de estudos para o desenvolvimento de técnicas de sutura que sejam capazes de realizar o fechamento primário dessas feridas com alívio de tensão, garantindo uma cicatrização adequada e evitando complicações como deiscência, edema, sangramento e infecção. Método: Esta pesquisa tratou-se de um estudo piloto, sendo a primeira apresentação da técnica de Sutura em Polia Retificada para síntese de feridas de pele tensionadas através do acompanhamento prospectivo, duplo-cego, de uma série de casos de 8 pacientes randomicamente admitidos no centro cirúrgico de um hospital de alta complexidade de uma cidade de médio porte. Resultados: A Sutura em Polia Retificada é uma técnica versátil e apta para lidar com feridas de pele tensionadas, uma vez que no intraoperatório conseguiu fechar por primeira intenção lesões de até 6,5 centímetros e de diferentes regiões tensionadas sem necessidade do uso de técnicas mais complexas, como retalhos, enxertos, zetaplastia e fechamento por segunda intenção. Além disso, no pós-operatório, houve redução dos escores da POSAS, indicando um processo de cicatrização satisfatório tanto para os observadores quanto para o paciente. É imprescindível mencionar, também, que o desfecho mais temido no seguimento dos pacientes com feridas tensionadas submetidos a fechamento primário - a deiscência - foi completamente evitado. Conclusão: A técnica é simples, confiável, segura e reprodutível, com curta curva de aprendizagem, de forma que a Sutura em Polia Retificada pode ser considerada como uma nova ferramenta a ser integrada ao arsenal cirúrgico.

Introduction: The synthesis of tensioned skin wounds is an area that has been the subject of studies for the development of suturing techniques that are capable of performing the primary closure of these wounds with tension relief, ensuring adequate healing, and avoiding complications such as dehiscence, edema, bleeding, and infection. Method: This research was a pilot study, being the first presentation of the Rectified Pulley Suture technique for the synthesis of tensioned skin wounds through prospective, double-blind monitoring of a series of cases of 8 patients randomly admitted to the surgical center of a high-complexity hospital in a mediumsized city. Results: Rectified Pulley Suture is a versatile technique suitable for dealing with tensioned skin wounds, since intraoperatively it was able to close, by first intention, lesions measuring up to 6.5 centimeters and in different tensioned regions without the need for the use of more extensive techniques. complex, such as flaps, grafts, Z-plasty, and secondary intention closure. Furthermore, post-operatively, there was a reduction in POSAS scores, indicating a satisfactory healing process for both observers and the patient. It is also essential to mention that the most feared outcome in the follow-up of patients with tension wounds undergoing primary closure - dehiscence - was completely avoided. Conclusion: The technique is simple, reliable, safe, and reproducible, with a short learning curve, so the Rectified Pulley Suture can be considered a new tool to be integrated into the surgical arsenal.

ABSTRACT Background: Non-invasive conservative treatment of splenic trauma reduces the rate of unnecessary surgical interventions and depends on the type of healthcare center involved. Objective: The aim of this study is to describe the outcomes of non-invasive conservative treatment in patients with blunt abdominal trauma and splenic injury and their correlation with the preoperative variables. Material and methods: We conducted a retrospective and observational study of patients admitted with blunt abdominal trauma and splenic injury between 2012 and 2022. The variables analyzed were kinematics of trauma, lesion severity on computed tomography images, amount of hemoperitoneum, type of unit of hospitalization and results of non-invasive conservative treatment. Results: Among 102 patients, the most common kinematics of trauma was motorcycle-to-car collisions (47.1%); the success rate of non-invasive conservative treatment was 66.6%, and was associated with lesion severity on computed tomography images (p < 0.001), amount of hemoperitoneum (p < 0.001), presence of other injuries (p < 0.001), severe trauma brain injury (p < 0.009), and type of unit of hospitalization (p < 0.002). Conclusion: Despite the absence of recommended human and technological resources, the results of non-invasive conservative treatment in this series were comparable to those obtained in high complexity centers.

Fístula enterocutánea: un enfoque desde las generalidades y el estado nutricional / Enterocutaneous fistula: An approach based on generalities and nutritional status

Introducción. Una fístula es una conexión anormal entre dos superficies epitelizadas. Cerca del 80 % de las fístulas entero-cutáneas son de origen iatrogénico secundarias a cirugía, y un menor porcentaje se relacionan con traumatismos, malignidad, enfermedad inflamatoria intestinal o isquemia. La morbilidad y las complicaciones asociadas pueden ser significativas, como la desnutrición, en la que intervienen múltiples factores. Métodos. Se realizó una búsqueda de la literatura en las bases de datos de PubMed, Google Scholar y SciELO, utilizando las palabras claves descritas y se seleccionaron los artículos más relevantes de los últimos años. Resultados. La clasificación de las fístulas se basa en su anatomía, su gasto o secreción diaria y su localización. Existe una tríada clásica de las complicaciones: sepsis, desnutrición y anomalías electrolíticas. El control del gasto de la fístula, el drenaje adecuado de las colecciones y la terapia antibiótica son claves en el manejo precoz de estos pacientes. Los estudios recientes hacen hincapié en que la sepsis asociada con la desnutrición son las principales causas de mortalidad. Conclusiones. Esta condición representa una de las complicaciones de más difícil y prolongado tratamiento en cirugía abdominal y colorrectal, y se relaciona con importantes tasas de morbilidad, mortalidad y altos costos para el sistema de salud. Es necesario un tratamiento multidisciplinario basado en la reanimación con líquidos, el control de la sepsis, el soporte nutricional y el cuidado de la herida, entre otros factores.

Introduction. A fistula is an abnormal connection between two epithelialized surfaces. About 80% of enterocutaneous fistulas are of iatrogenic origin secondary to surgery, and a smaller percentage are related to trauma, malignancy, inflammatory bowel disease or ischemia. The associated morbidity and complications can be significant, such as malnutrition, in which multiple factors intervene. Methods. A literature search was carried out in the PubMed, Google Scholar and SciELO databases using the keywords described and the most relevant articles from recent years were selected. Results. The classification of fistulas is based on their anatomy, their daily secretion output, and their location. There is a classic triad of complications: sepsis, malnutrition and electrolyte abnormalities. Control of fistula output, adequate drainage of the collections and antibiotic therapy are key to the early management of these patients. Recent studies emphasize that sepsis associated with malnutrition are the main causes of mortality. Conclusions. This condition represents one of the most difficult and prolonged complications to treat in abdominal and colorectal surgery, and is related to significant rates of morbidity, mortality and high costs for the health system. Multidisciplinary treatment based on fluid resuscitation, sepsis control, nutritional support, and wound care, among other factors, is necessary.

Recommendations from Annals of Surgical Oncology： Clinical guidelines for extrahepatic cholangiocarcinoma and gallbladder carcinoma / 临床肝胆病杂志

Biliary tract carcinoma （BTC） is a type of gastrointestinal tumor with a low incidence rate and a strong invasive ability， mainly including intrahepatic cholangiocarcinoma （ICC）， extrahepatic cholangiocarcinoma （ECC）， and gallbladder carcinoma （GC）， often accompanied by local progression or distant metastasis. Surgery is often the preferred treatment method for patients with local resectable tumor； however， there is still a high risk of recurrence after radical surgery. Therefore， multiple treatment modalities are often required for BTC patients， including surgical resection， systemic treatment （such as targeted therapy， chemotherapy， and immunotherapy）， and/or a combination of local treatment methods. With the development of the field of BTC， it is critical for surgical oncologists to understand and master the latest surgical strategies and the best patient selection and management systems. In view of the complexity of treatment and the continuous development of diagnosis and treatment techniques， Annals of Surgical Oncology， an authoritative American journal of cancer surgery， recently published the practical diagnosis and treatment guidelines for hepatobiliary tumors， including hepatocellular carcinoma （HCC）， ICC， ECC， and GC， aiming to provide more evidence-based evidence for the clinical management and decision-making of patients with hepatobiliary tumors. Due to the limitations of length and different emphases， this article mainly introduces the recommendations for the evaluation points and clinical treatment of ECC and GC in the guidelines， so as to provide a reference for clinical practice.

Impact of COVID-19 on theoretical knowledge and clinical practice in dentistry of Piracicaba Dental School students: a cross-sectional study

Aim: To assess the opinion of the students on the impact of COVID-19 pandemic on theoretical knowledge and clinical practice in dentistry at the Piracicaba Dental School ­ FOP/UNICAMP. Methods: A questionnaire was applied using the Google Forms platform, containing 20 questions related to the impacts of the pandemic on knowledge, mental health, and clinical and laboratory practice of dentistry. The satisfaction of the students with teaching was also evaluated. A total of 120 questionnaires were analyzed using R software, through tables and graphs of absolute and relative frequencies distribution. Results: COVID-19 affected the lives of 99% students who participated in the study. Due to distance learning resulting from the COVID-19 pandemic, 50% of the students considered locking or dropping out of college. Operative dentistry was the curricular component most affected by distance and lack of clinical practice. Although most students agreed that the workload of practical disciplines was or would be replaced, 95% felt some kind of deficit in clinical and laboratory practice even with the replacement of the workload. In addition, 93.3% of the students were afraid of not becoming a qualified professional due to the deficiencies on theoretical knowledge and clinical practice caused by the pandemic. Conclusions: Students showed dissatisfaction with the deficiency of clinical and laboratory practice resulting from the pandemic in operative dentistry curricular component. They reported fear and insecurity with their future professional lives. The indication of remote classes for dentistry should only be carried out in emergencies because this is an essentially practical course that suffers losses in learning

Trauma in the vertebral spine: determining factors in the time for the surgery / Traumatismo na coluna vertebral: fatores determinantes no tempo para realização da cirurgia / Lesiones en la columna vertebral: factores determinantes en el tiempo para la cirugía

ABSTRACT Objective: Quantify the time elapsed between the arrival of the patient with surgical trauma in the spine at the emergency room and the completion of the surgical procedure, analyzing the factors that may have influenced this process. Methods: Retrospective study that included individuals of both sexes aged between 18 and 100 years who arrived at a tertiary trauma center with surgical fractures in the spine. Patients treated between March 2018 and March 2022 were included in the sample. All data to compose the study sample were collected from secondary data sources (medical records). Results: Medical records of 259 patients with spinal injuries were evaluated. Approximately one-third of the patients were operated on between 13h and 24h, and the other third over 72h. Only 6.6% were operated within 12 hours. The mean time to perform the surgical process was 84.3 ± 144.6 hours. Surgical intervention for most patients (59.1%) occurred within the first 48 hours. Patients with systemic arterial hypertension and patients with at least one comorbidity had a statistically longer mean waiting time for the surgical procedure than patients who did not have these characteristics. Conclusion: Most surgical interventions occurred in the first 48 hours, which is considered early. In addition, some factors, such as the existence of comorbidities, are directly associated with the time it takes to perform the surgical procedure. Level of Evidence II; Retrospective Prognostic.

What is the applicability of tubal ligation with the vaginal natural orifice transluminal endoscopic surgery technique and its value in patient comfort?

SUMMARY OBJECTIVE: The aim of this study was to observe the feasibility of the tubal/adnexal approach using vaginal natural orifice transluminal endoscopic surgery and compare its contribution with surgeon ergonomics and postoperative patient comfort with that of conventional laparoscopy. METHODS: We completed this study retrospectively with 47 patients. Patients were followed at their postoperative first month. We analyzed the usability of the vaginal natural orifice transluminal endoscopic surgery method over conventional laparoscopy by comparing the demographics, surgical data, and postoperative findings collected between the two groups. RESULTS: Patients in the conventional laparoscopy group were older (39.1±3.3 years) than those in the vaginal natural orifice transluminal endoscopic surgery patient group (p=0.005). Pain intensity 24 h after surgery was lower in the vaginal natural orifice transluminal endoscopic surgery group (p=0.003), while sexual function and dyspareunia did not differ between the two groups in the first month. Patients in the vaginal natural orifice transluminal endoscopic surgery group were more relieved about painlessness and the comfort it brought than the conventional laparoscopy group (p=0.027, χ2=12.56). CONCLUSION: Patients subjected to the vaginal natural orifice transluminal endoscopic surgery procedure showed higher levels of satisfaction, less postoperative pain, and greater comfort than those subjected to conventional laparoscopy.

Quality of emergency oncological surgery: time for advanced oncological life support

SUMMARY In the emergency care of cancer patients, in addition to cancer-related factors, two aspects influence the outcome: (1) where the patient is treated and (2) who will perform the surgery. In Brazil, a significant proportion of patients with surgical oncological emergencies will be operated on in general hospitals by surgeons without training in oncological surgery. OBJECTIVE: The objective was to discuss quality indicators and propose the creation of an urgent oncological surgery advanced life support course. METHODS: Review of articles on the topic. RESULTS: Generally, nonelective resections are associated with higher rates of morbidity and mortality, as well as lower rates of cancer-specific survival. In comparison to elective procedures, the reduced number of harvested lymph nodes and the higher rate of positive margins suggest a compromised degree of radicality in the emergency scenario. CONCLUSION: Among modifiable factors is the training of the emergency surgeon. Enhancing the practice of oncological surgery in emergency settings constitutes a formidable undertaking that entails collaboration across various medical specialties and warrants endorsement and support from medical societies and educational institutions. It is time to establish a national registry encompassing oncological emergencies, develop quality indicators tailored to the national context, and foster the establishment of specialized training programs aimed at enhancing the proficiency of physicians serving in emergency services catering to cancer patients.

Early Outcomes of Minimally Invasive Right Anterior Thoracotomy vs. Median Full Sternotomy in Isolated Aortic Valve Replacement: A Propensity Score Analysis

ABSTRACT Introduction: This study aimed to compare the early postoperative outcomes of right anterior thoracotomy minimally invasive aortic valve replacement (RAT-MIAVR) surgery with those of median full sternotomy aortic valve replacement (MFS-AVR) approach with the goal of identifying potential benefits or drawbacks of each technique. Methods: This retrospective, observational, cohort study included 476 patients who underwent RAT-MIAVR or MFS-AVR in our hospital from January 2015 to January 2023. Of these, 107 patients (22.5%) underwent RAT-MIAVR, and 369 patients (77.5%) underwent MFS-AVR. Propensity score matching was used to minimize selection bias, resulting in 95 patients per group for analysis. Results: After propensity matching, two groups were comparable in preoperative characteristics. RAT-MIAVR group showed longer cardiopulmonary bypass time (130.24 ± 31.15 vs. 117.75 ± 36.29 minutes, P=0.012), aortic cross-clamping time (76.44 ± 18.00 vs. 68.49 ± 19.64 minutes, P=0.004), and longer operative time than MFS-AVR group (358.47 ± 67.11 minutes vs. 322.42 ± 63.84 minutes, P=0.000). RAT-MIAVR was associated with decreased hospitalization time after surgery, lower postoperative blood loss and drainage fluid, a reduced incidence of mediastinitis, increased left ventricular ejection fraction, and lower pacemaker use compared to MFS-AVR. However, there was no significant difference in the incidence of major complications and in-hospital mortality between the two groups. Conclusion: RAT-MIAVR is a feasible and safe alternative procedure to MFS-AVR, with comparable in-hospital mortality and early follow-up. This minimally invasive approach may be a suitable option for patients requiring isolated aortic valve replacement.

Resultados: Se hace referencia a cuatro de las situaciones transoperatorias más frecuentes en este tipo de fractura. Se mencionan la conminución de la pared medial, como identificar esta situación y su conducta. En relación a las lesiones asociadas, se recomienda primero estabilizar el antebrazo y luego la fractura supracondílea. Para las fracturas inestables en flexión se recomienda la técnica a emplear. Por su parte, la conversión de la reducción cerrada a abierta está justificada en ciertas circunstancias que de forma detallada se describen en el trabajo. Conclusiones: Las fracturas supracondíleas del húmero en el niño son tratadas en su mayoría mediante tratamiento quirúrgico. Durante el transoperatorio se pueden presentar situaciones para las cuales el médico tratante debe estar preparado.

Introduction: Supracondylar fractures of the humerus in children are generally treated surgically, during surgery intervention may occur specific situations in this type of patient. Objective: To update and provide information on some of the intraoperative situations in patients with supracondylar fracture of the humerus. Methods: The search and analysis of the information was carried out in a period of 61 days (September 1st to October 31st, 2022) and search words related to the investigation were used. Based on the information obtained, a bibliographic review of a total of 245 articles published in the PubMed, Hinari, SciELO and Medline databases was carried out using the EndNote search manager and reference administrator, of which 29 selected citations were used to carry out the review, 28 of the last five years. Results: Reference is made to four of the most frequent intraoperative situations in this type of fracture. Comminution of the medial wall, how to identify this situation and its behavior are mentioned. In relation to associated injuries, it is recommended to first stabilize the forearm and then the supracondylar fracture. For unstable fractures in flexion, the technique to be used is recommended. For its part, the conversion from closed to open reduction is justified in certain circumstances that are described in the article. Conclusions: Supracondylar fractures of the humerus in children are mostly treated by surgical treatment. During the trans-operative period situations may arise for which the treating physician must be prepared.

Preoperative co-application of bevacizumab and tissue plasminogen activator in vitrectomy for proliferative diabetic retinopathy

ABSTRACT Purpose: To investigate the clinical benefits of the co-application of bevacizumab and tissue plasminogen activator as adjuncts in the surgical treatment of proliferative diabetic retinopathy. Methods: Patients who underwent vitrectomy for proliferative dia-betic retinopathy complications were preoperatively given in-travitreal injection with either bevacizumab and tissue plasminogen activator (Group 1) or bevacizumab alone (Group 2). Primary outcomes were surgery time and number of intraoperative iatrogenic retinal breaks. Secondary outcomes included changes in the best-corrected visual acuity and postoperative complications at 3 months postoperatively. Results: The mean surgery time in Group 1 (52.95 ± 5.90 min) was significantly shorter than that in Group 2 (79.61 ± 12.63 min) (p<0.001). The mean number of iatrogenic retinal breaks was 0.50 ± 0.59 (0-2) in Group 1 and 2.00 ± 0.83 (0-3) in Group 2 (p<0.001). The best-corrected visual acuity significantly improved in both groups (p<0.001). One eye in each group developed retinal detachment. Conclusion: Preoperative co-application of bevacizumab and tissue plasminogen activator as adjuncts in the surgical treatment of proliferative diabetic retinopathy shortens the surgery time and reduces the number of intraoperative iatrogenic retinal breaks.

Evaluation of arthrogrypotic foot treatment: minimum 10 years follow-up / Avaliação do tratamento do pé artrogripótico: seguimento mínimo de 10 anos

ABSTRACT Objective: To evaluate patients with arthrogryposis submitted to extensive surgical treatment with a minimum of 10 years of follow-up regarding the clinical and radiological aspects and the quality of life, using the 36-Item Short Form (SF-36) and the Disease-Specific Instrument (DSI). Methods: A retrospective study selected 33 patients, totaling 64 operated feet. Results: The mean age of the patients was 17.9 years (12-39 years), and the mean follow-up time was 14.8 years (11-17). Amyoplasia represented 78.7% of syndromic diagnoses. Isolated posteromedial lateral release (PMLR) was performed in 21.8% of the feet, 27.2% of which required additional bone surgery, and about 50 feet (78.1%) were submitted to PMLR, lateral column shortening, and/or talectomy. In total, 46 talectomies were performed (71.8% of the feet), out of which 44 were the first procedure of choice. SF-36 questionnaire was evaluated and showed that 93.9% of the patients did not have restrictive and disabling pain, and the same percentage considered themselves as healthy and had good expectations for the future. Conclusion: Arthrogrypotic feet are difficult to treat, require many recurrent surgical procedures, and relapses are the rule. Stiffness is a common feature of these feet, and residual deformities were frequent. Level of Evidence IV; Case Series, Therapeutic Studies.

RESUMO Objetivo: Avaliar pacientes com artrogripose submetidos a tratamento cirúrgico convencional com um mínimo de 10 anos de seguimento quanto aos aspectos clínicos, radiológicos e qualidade de vida, utilizando o questionário de 36 itens Short Form 36 (SF-36) e o Instrumento específico de Doenças (IED). Método: No estudo retrospectivo foram avaliados 33 pacientes, totalizando 64 pés operados. Resultados: A média de idade foi de 17,9 anos (12-39 anos), e o tempo médio do seguimento foi de 14,8 anos (11-17). A amioplasia representou 78,7% dos diagnósticos sindrômicos. A liberação posteromedial lateral isolada (LP MI) foi realizada em 21,8% dos pés, 27,2%, com cirurgia óssea adicional, e cerca de 50 pés (78,1%) foram submetidos a LPM (liberação póstero medial), encurtamento da coluna lateral e/ou talectomia. Foram realizadas 46 talectomias (71,8% dos pés), sendo em 44 o procedimento de primeira escolha. O questionário SF-36 evidneciou que 93,9% dos pacientes estavam sem dor restritiva e incapacitante, consideravam-se saudáveis, com boas expectativas para o futuro. Conclusão: Os pés artrogripóticos são de difícil tratamento, requerendo muitos procedimentos cirúrgicos recorrentes. A rigidez é uma característica comum desses pés e as deformidades residuais foram frequentes. Estudos futuros poderão mostrar se haverá diferença no resultado do tratamento desses pés aplicando a abordagem inicial atual, mais conservadora.

Hook assisted reduction in cephalomedullary nailing without traction table / Redução assistida por gancho em haste cefalomedular sem mesa de tração

ABSTRACT Introduction: Proximal femoral nailing for intertrochanteric femur fracture is sometimes a challenging procedure without a traction table, especially if complicated fracture pattern. We aimed to overcome this difficulty with the hook. Materials and Methods: A retrospective study of 60 patients. 28 of the patients reduction was necessitated with a hook (group 1). The other patients did not need to use this technique (group 2, n=32). The collo-diaphyseal angle, lag screw placement, and tip-apex distance were measured using radiographs. Results: There were statistically significant differences between the two groups regarding the Garden Alignment Index, postoperative collo-diaphyseal angle measurements, and tip-apex distance. The Garden Alignment Index was found as 163.92 degrees (dg.) In the frontal plane in group 1, and 154.78 dg in group 2, respectively. In group 1, the tip-apex distance was 16.05 cm, whereas it was 25.32 cm in group 2. The collo-diaphyseal angle was 133.1º in group 1, and 128.65º in group 2. Conclusions: The hook-assisted reduction is beneficial when operating without a traction table; however, it can also be a part of the surgeons' equipment even when operating on a traction table. When difficulties in obtaining an ideal anatomical reduction in displaced intertrochanteric femoral fractures, we suggest using the hook-assisted reduction technique.

RESUMO Introdução: Frequentemente, a fixação do fêmur proximal para fratura intertrocantérica do fêmur sem uma mesa de tração é um procedimento desafiador, especialmente se o padrão da fratura for complicado. O objetivo foi superar essa dificuldade utilizando um gancho. Materiais e métodos: Trata-se de um estudo retrospectivo de 60 pacientes. Em 28 desses, a redução foi necessária com um gancho (grupo 1). Os outros pacientes não precisaram usar essa técnica (grupo 2, n=32). O ângulo colo-diafisário, a colocação do parafuso lag e a distância ponta-ápice foram medidos por meio de radiografias. Resultados: Houve diferenças estatisticamente significativas entre os dois grupos com relação ao Índice de Alinhamento de Garden, às medidas do ângulo colo-diafisário pós--operatório e à distância ponta-ápice. O índice de alinhamento de Garden foi de 163,92 graus (dg.) No plano frontal no grupo 1 e 154,78 dg no grupo 2, respectivamente. No grupo 1, a distância ponta-ápice foi de 16,05 cm, enquanto no grupo 2 foi de 25,32 cm. O ângulo colo-diafisário foi de 133,1 graus no grupo 1 e 128,65 graus no grupo 2. Conclusão: A redução assistida por gancho é benéfica quando se opera sem uma mesa de tração; no entanto, ela também pode fazer parte do equipamento do cirurgião mesmo quando se opera em uma mesa de tração. Quando houver dificuldades em obter uma redução anatômica ideal em fraturas femorais intertrocantéricas deslocadas, sugerimos o uso da técnica de redução assistida por gancho.

ABSTRACT Introduction: Severe acetabular bone defects can pose challenges in revision total hip replacement. The use of structural allografts and various sizes of grain allografts has been proposed as an alternative surgical technique for treating Paprosky type 3 acetabular defects. This study aimed to evaluate the long-term outcomes and potential complications associated with this approach. Methods: A retrospective review was performed on 102 hip reconstructions in patients with major acetabular bone loss, including 81 cases of type 3A and 21 cases of type 3B according to Paprosky's classification. Surgical procedures involved the use of structural allografts and various sizes of grain allografts in both reinforcement ring group and cementless cups group. Results: At a mean follow-up of 82.75 months, 76% of hips had no complications, while The others experienced pain changes in the cup position, post-operative dislocations, and infections. The mean pre-operative Modified Harris Hip Score improved in both groups at the last follow-up. Conclusion: The use of structural allografts and various sizes of grain allografts for treating type 3 acetabular defects in revision total hip replacement showed promising long-term outcomes and a low rate of complications.

Comparison of dynesys and hybrid system for multi-segmental ldd / Comparação entre dynesys e sistema híbrido para ldd multissegmental

ABSTRACT Objective: To compare effectiveness of Dynesys and hybrid system in treating patients with multi-segmental lumbar degenerative disease (LDD). Methods: Patients involved in this retrospective study were divided into Dynesys (n = 22) and Hybrid (n = 13) groups. Clinical outcomes were evaluated using Oswestry Disability Index (ODI), and Visual Analogue Scale (VAS). Radiologic evaluations included X-ray, MRI, and CT. Furthermore, different complications were analyzed. Results: At the last follow-up, ODI and VAS of each group were improved (p < 0.05), and the range of motion (ROM) of operating segments decreased. However, Dynesys group preserved a larger extent of ROM at the final follow-up (p < 0.05). ROM of the upper adjacent segment was increased in both groups (p < 0.05), while the disc heights were decreased at the final follow-up (p < 0.05). Besides, Dynesys group had a more obvious decrease in the disc height of dynamic segments (p < 0.05). No significant difference existed in complications between both groups (p > 0. 05). Conclusion: In our study, similar satisfactory results were obtained in both groups. Both surgical procedures can be employed as effective treatments for middle-aged and physically active patients with multi-segmental LDD. Level of Evidence III; Retrospective Comparative Study.

RESUMO Objetivo: Comparar a eficácia do Dynesys e do sistema híbrido no tratamento de pacientes com doença degenerativa lombar multissegmentar (DLD). Métodos: Os pacientes envolvidos neste estudo retrospectivo foram divididos em grupos Dynesys (n = 22) e Híbrido (n = 13). Os desfechos clínicos foram avaliados por meio do Oswestry Disability Index (ODI) e da Escala Visual Analógica (EVA). As avaliações radiológicas incluíram radiografia, ressonância nuclear magnética (RNM) e tomografia computadorizada. Ademais, diferentes complicações foram analisadas. Resultados: No acompanhamento final, o ODI e a EVA de todos os grupos melhoraram (p < 0,05), e houve diminuição da amplitude de movimento (ADM) dos segmentos operacionais. No entanto, o grupo Dynesys preservou uma maior extensão da ADM no acompanhamento final (p < 0,05). A ADM do segmento superior adjacente foi ampliada em ambos os grupos (p < 0,05), enquanto as alturas dos discos foram reduzidas no acompanhamento final (p < 0,05). No entanto, o grupo Dynesys apresentou uma redução mais evidente na altura do disco dos segmentos dinâmicos (p < 0,05). Não houve diferença significativa nas complicações entre esses dois grupos (p > 0,05). Conclusão: Neste estudo, resultados satisfatórios semelhantes foram obtidos em ambos os grupos. Ambos os procedimentos cirúrgicos podem ser empregados como tratamentos eficazes para pacientes de meia-idade e fisicamente ativos com LDD multissegmentar.

Treatment Trends in Paediatric Dentistry with Evolving Training and Education of Postgraduate Students in India: A Retrospective Study

ABSTRACT Objective: To assess and analyse the pattern of dental treatment services and their characteristics provided to children by evaluating the clinical use of materials and prevalence in material research in a major postgraduate paediatric tertiary care hospital in India over three years. Material and Methods: Institutionally approved retrospective analysis was conducted by auditing the clinical records of 2644 patients who visited and had treatment in the Outpatient and Inpatient Department of Paedodontics and Preventive Dentistry from January 2017 to December 2019. Clinical logbooks of postgraduate students were analysed by crosschecking with the department's data warehouse. Results: Out of the 2644 children who had treatment, more than two-thirds of them were in the age group of 4-7 years old. Around 5.6% of the patients were specially-abled children. Extraction (33.5%) was the most common treatment, followed by restorative treatment (29.1%). Endodontic treatment had a prevalence of 19.8%, with a reduced prevalence of preventive treatment care (0.5%). Patients who had traumatic tooth management included 2.8% of the study population. The prevalence of preventive care was found to be 2.1%. The teaching curriculum with theoretical and clinical skill practices was under the country's assigned authority. Conclusion: Despite advancements in paediatric dentistry, more children had extraction treatment with less observed utilization of preventive care. The widening of the training prospectus includes comprehensive care and an amplified focus on preventive care in the academic curriculum of paediatric postgraduates, which is the need of the hour.
