ABSTRACT

Resumen El sarcoma de Ewing es una neoplasia rara y altamente agresiva que afecta con cierta predilección adolescentes varones. La incorporación de terapia neoadyuvante y nuevas técnicas quirúrgicas ha mejorado la supervivencia. Presentamos el caso de un varón de 41 años con sarcoma de Ewing de pared torácica, quien recibió tratamiento multimodal consistente en quimio-radioterapia concurrente y tratamiento qui rúrgico, y alcanzó respuesta patológica completa. El sarcoma de Ewing rara vez se presenta en la edad adulta y, cuando lo hace, suele tener mal pronóstico. El tratamiento multimodal de pacientes mayores de 40 años ha probado mejorar los resultados oncológicos.


Abstract Ewing sarcoma is a rare and highly aggressive neoplasm that occurs most frequently in male adolescents. The incorporation of neoadjuvant therapy and new surgical techniques has improved survival. We present the case of a 41-year-old man diagnosed with Ewing sarcoma of the chest wall, whose tumor showed a pathological complete response to a multimodal treatment consisting of concurrent chemotherapy, radiotherapy, and surgical resection. Ewing sarcoma rarely occurs in adults, who generally have a worse prognosis. A multimodal approach for the treatment of patients older than 40 years has proven to improve oncological results.

ABSTRACT

RESUMO Objetivo: Avaliar os resultados da facotrabeculectomia em seguimento igual ou superior a 5 anos. Métodos: Estudo retrospectivo, de intervenção e analítico realizado no centro cirúrgico da clínica de olhos de Juazeiro do Norte com pacientes operados no período de 2006 a 2013. Foram envolvidos na investigação 34 olhos de 29 pacientes com catarata senil e glaucoma primário de ângulo aberto submetidos à facotrabeculectomia. Foi criado um escore de risco de dano glaucomatoso variando de 0 a 5 ao avaliar pressão intraocular, escavação do disco óptico, número de drogas hipotensoras utilizadas para o tratamento do glaucoma e a idade do paciente em anos. A amostra foi de conveniência e pareada. Foi utilizado o teste de Wilcoxon pareado para a verificação de diferenças entre médias. Foi aceito p< 0,05 para a rejeição da hipótese de nulidade. O estudo foi aprovado pelo comitê de ética da plataforma Brasil e segue a resolução 466 do Conselho Nacional de Saúde. Resultados: A média da acuidade visual foi significantemente maior após o seguimento de 5 anos (média pré-operatória 0,42 +/- 0,23 ver-sus média pós-operatória 0,62 +/- 0,29 - p=0,0031). A média dos escores de risco para dano glaucomatoso após 5 anos de seguimento foi significativamente menor quando comparado ao pré-operatório (media pré-operatória: 9,47 +/- 1,61 versus média pós-operatória 6,55 +/- 2,21) p < 0,0001, considerado extremamente significante. Conclusão: A facotrabeculectomia foi significantemente efetiva na melhora da acuidade visual e na redução do risco de dano glau-comatoso após seguimento pós-operatório igual ou superior a 5 anos.


ABSTRACT Objective: To evaluate the results of phacotrabeculectomy in a follow-up of five years or more. Methods: Retrospective, interventional and analytical study that was carried out in the surgical center of clínica de olhos do juazeiro with patients operated on from 2006 to 2013. 34 eyes of 29 patients with senile cataract and primary open-angle glaucoma, who underwent phacotrabeculectomy were involved in the investigation. A risk score for glaucomatous dam-age ranging from 0 to 5 when evaluating intraocular pressure, excavation of the optic disc, number of hypotensive drugs used to treat glaucoma and the patient's age in years. The sample was of convenience and paired. The paired Wilcoxon test was used to verify differences be-tween means. P <0.05 was accepted for the rejection of the null hypothesis. The study was approved by the ethics committee of the Brazil platform and follows the principles of resolu-tion 466 of the National Health Council. Results: The mean visual acuity was significantly higher after a five-year follow-up (preoperative average 0.42 +/- 0.23 versus postoperative average 0.62 +/- 0.29 - p = 0.0031). The average risk score for glaucomatous damage after five years of follow-up was significantly lower when compared to the preoperative (preoperative mean: 9.47 +/- 1.61 versus postoperative mean 6.55 +/- 2, 21) p <0.0001, considered extremely significant. Conclusion: Phacotrabeculectomy was significantly effective in improving visual acuity and reducing the risk of glaucomatous damage after a five-year postoperative follow-up.

ABSTRACT

ABSTRACT Hypothesis: Endoclip can be used as fiducial marker in urology. Objective: To assess the feasibility, cost effectiveness and reliability of endoclips as novel fiducial markers in precision radiotherapy, as part of a trimodality bladder-preserving treatment (TBPT) of muscle-invasive bladder carcinoma. Materials and Methods: This retrospective study was performed at Weifang People's Hospital (Weifang, China) from January 2015 to June 2018. A total of 15 patients underwent TBPT. Endoclips were applied to healthy edges of the resected bladder wall as novel fiducial markers. Radio-sensitizing chemotherapy and routine precision radiotherapy were given. The number and position of the endoclips during radiotherapy sessions were monitored. Complications and tumor recurrence were analyzed. Results: The mean age (±standard deviation) of the patients was 67±10 years (range 46-79). There were 3 females and 12 males. Forty-nine endoclips were applied in all patients (3.3±0.8). The tumor was completely visibly resected in all patients. The number of endoclips remained the same through the planned last radiotherapy session (3.3±0.8), i.e., none were lost. All endoclips were removed after the last radiotherapy session. The average number of follow-up months was 38.9±13.2 (range 11-52). There were no procedure-related complications at discharge or follow-up. At one-year, overall recurrence-free survival was 93.3%. Two patients had recurrences at 18 months and 10 months after TBPT, respectively, and salvage radical cystectomy was performed with no further recurrences. Another patient died due to metastasis 9 months after the completion of therapy. Conclusions: Endoclips are reliable, safe and cost-effective as novel fiducial markers in precision-radiotherapy post-TBPT.

ABSTRACT

El cáncer papilar de tiroides es el tumor tiroideo más común en la infancia. En estadios avanzados, puede presentarse con cuadro de insuficiencia respiratoria. El tratamiento de elección es la tiroidectomía total y iodo radiactivo. En tumores irresecables, se debería considerar terapia con inhibidores multicinasa.Niña de 10 años de edad derivada por insuficiencia respiratoria progresiva. Se realizó el diagnóstico de cáncer papilar de tiroides con metástasis pulmonares. Por presentar un tumor irresecable no pasible de cirugía, se indicó el uso compasivo de lenvatinib, que mostró una rápida y favorable respuesta clínica con resolución de la insuficiencia respiratoria al noveno día del tratamiento.El diagnóstico temprano de cáncer papilar de tiroides previene la grave morbilidad respiratoria ocasionada por diagnósticos tardíos. Podría considerarse el uso de lenvatinib como alternativa previa a las terapias de primera línea (cirugía e iodo radiactivo) en casos de enfermedad con gran compromiso local y a distancia.


Papillary thyroid cancer is the most common thyroid tumor in childhood. In advanced stages, it can present with respiratory failure. The treatment of choice is total thyroidectomy and radioactive iodine. In cases of unresectable tumors, therapy with multikinase inhibitors should be considered. A 10-year-old girl was referred for progressive respiratory failure. A diagnosis of papillary thyroid cancer with pulmonary metastases was made. Due to the presence of an unresectable tumor not subject to surgery, the compassionate use of lenvatinib was indicated, showing a rapid and favorable clinical response with resolution of respiratory failure on the ninth day.Early diagnosis of papillary thyroid cancer prevents severe respiratory morbidity caused by late diagnoses. The use of lenvatinib should be considered as a previous step towards first-line therapies (surgery and radioactive iodine) in cases with great local and distant involvement.

ABSTRACT

RESUMO O Lasik é a técnica de cirurgia refrativa mais utilizada no mundo. Apesar de segura e efetiva, ela pode levar a algumas complicações. O crescimento epitelial pós-Lasik é uma complicação pós-operatória incomum, com prevalência maior em casos de retratamento. Geralmente, é um achado não progressivo e assintomático, que não requer tratamento, mas, em uma minoria de pacientes, os sintomas podem ser clinicamente significantes e variados. O tratamento é feito com debridamento mecânico do crescimento epitelial, mas alguns recursos adjuvantes também podem ser utilizados. O presente estudo consiste em um relato de caso de paciente com crescimento epitelial pós-Lasik que apresentou quatro recidivas após intervenções de debridamento epitelial, sutura de lamela corneana e ablação a laser. No quinto procedimento, o paciente foi finalmente tratado com combinação de debridamento epitelial, uso de álcool a 20% e cola de fibrina. Entretanto, a regressão do crescimento epitelial e a melhora da acuidade visual só ocorreram ao longo dos meses após a intervenção, o que mostra a importância de esperar um tempo para que ocorra a melhora da visão no pós-operatório, evitando-se reintervenções.


ABSTRACT Lasik is the most often performed laser refractive surgery worldwide. Despite its efficacy and safety, some complications may occur. Epithelial ingrowth is a rare postoperative complication of Lasik, with an increased prevalence in cases of retreatment. Epithelial ingrowth is usually a nonprogressive and asymptomatic finding, which requires no treatment; however, in a minority of cases, symptoms may be clinically significant and diverse. Treatment is done with mechanical debridement of the affected interface, and additional interventions may be required. This study reported a case of recalcitrant epithelial ingrowth after Lasik, whichrelapsed four times after mechanical debridement, flap lift and laser ablation. In the fifth intervention, the patient was finally treated with a combined scraping/use of 20% alcohol and fibrin glue. However, regression of epithelial ingrowth and better visual acuity were only observed some months after the intervention, which shows the importance of waiting for better vision in the postoperative period, thus avoiding new reinterventions.

ABSTRACT

ABSTRACT No reports about treatments applied by orofacial motricity experts, in craniofacial trauma, were found in the specialized literature. However, their knowledge, added to that of the aesthetic area, would be useful in the rehabilitation of scars. The aim of this work is to describe the mixed use of orofacial motor skills, muscle balance massage and scar management in a patient with soft tissues facial trauma. During the initial evaluation, a decrease in the vertical and horizontal oral opening and in the mimic movements, facial asymmetry and marked scars that affected the oral phase of swallowing, chewing (bolus formation), lip mobility, compromising speech intelligibility and, significantly, aesthetics, were observed. Myofunctional therapy lasted 12 months, during which the patient underwent three surgeries. The process was divided into an intensive phase (six months, two weekly sessions) and a follow-up phase (six months, one weekly session), which ended when the indicators evaluated at the beginning were stable, showing improvements in scars condition and appearance, as well as in orofacial functions, including pre-post therapy self-perception and greater muscular mobility, reflecting a management with an integrative approach.


RESUMEN En la literatura especializada no se encontraron reportes sobre tratamientos aplicados por expertos en motricidad orofacial en traumas craneofaciales, sin embargo, sus conocimientos, sumados a los del área estética serían útiles en la rehabilitación de cicatrices. El objetivo del trabajo es describir el uso mixto de técnicas de motricidad orofacial, masaje de equilibrio muscular y manejo de cicatrices en un paciente con trauma facial en tejidos blandos. En la evaluación inicial se observó: disminución en la apertura oral vertical y horizontal y de los movimientos de la mímica, asimetría facial y marcadas cicatrices que afectaban la fase oral de la deglución, la masticación (formación del bolo), la movilidad labial, comprometiendo la inteligibilidad del habla y de modo significativo la estética. La terapia miofuncional duró 12 meses, en medio de la cual el paciente tuvo tres intervenciones quirúrgicas. El proceso se dividió en una fase intensiva (seis meses con dos sesiones semanales) y otra de seguimiento (seis meses con una sesión semanal), que concluyó al estabilizarse los indicadores evaluados al inicio, evidenciándose mejoras en el estado y apariencia de las cicatrices, en las funciones orofaciales, incluida la autopercepción pre -post terapia, y mayor movilidad de la musculatura, asumiendo un manejo con enfoque integrador.

ABSTRACT

Extraskeletal Ewing sarcoma is a rare event, and extraskeletal Ewing sarcoma of the thyroid gland is even rarer. It has non-specific clinical manifestation and difficulty in early diagnosis. The diagnosis mainly depends on histology and immunohistochemistry. It possesses the features of high malignancy, high rate of local recurrence, and distant metastasis. Currently, the aggressive multimodal treatment contains surgery, chemotherapy, and radiotherapy. This study presented a case of extraskeletal Ewing sarcoma arising in the thyroid gland of a 30-year-old woman, who presented with supraclavicular mass and sense of dysphagia obstruction in Department of Otolaryngology, Head and Neck Surgery, Second Xiangya Hospital, Central South University in 2018. Imaging studies demonstrated a cystic-solid mass in inferior of the left leaf of thyroid gland and in the posterior of the trachea and esophagus. The patient underwent localized tumor resection. The pathological diagnosis revealed that it was a small round cell tumor, and the immunohistochemistry results were considered to be extraskeletal Ewing sarcoma. Subsequently, the patient was given chemotherapy and local radiation therapy. There was no evidence of tumor recurrence or metastasis.

ABSTRACT

Intra-abdominal infections(IAIs) are common surgical emergencies and complications, which usually need multidisciplinary management including surgeons, intensivists, infectious disease experts, microbiologists, and clinical pharmacists. Based on international and domestic guidelines and recent advances, a number of experts' statements of consensus, with a problem-oriented approach, were made on the cornerstones of effective treatment of IAIs such as early recognition, etiology identification, adequate source control, and appropriate antimicrobial therapy. Main recommendations include concepts of intra-abdominal infection, pathoqen diagnosis precautions; surgical intervention principles and strategies of specific causes including acute appendicitis, upper gastrointestinal perforation, lower gastrointestinal perforation, acute biliary infection, liver abscess, severe acute pancreatitis, pancreatic fistula, biliary fistula, anastomotic leakage, gastrointestinal perforation, as well as perforation due to endoscopic procedure etc.; principles of antimicrobial therapy, dosage of antibiotics in specific population and pathophysiological state; and systematic support of severe infection such as early resuscitation and nutrition support.

ABSTRACT

Immunotherapy has opened a new era in cancer treatment. Drugs represented by immune checkpoint inhibitors have led to important breakthroughs in the treatment of various solid tumors, greatly improving the survival rate of cancer patients. Many types of immunotherapeutic drugs have become widely available; however, their efficacy is variable, and relatively few patients with advanced cancer experience life-altering durable survival, reflecting the complex and highly regulated nature of the immune system. The research field of cancer immunotherapy (CIT) still faces many challenges in pursuing the broader social goal of "curing cancer." Increasing attention has been paid to strengthening the understanding of the molecular or cellular drivers of resistance to immunotherapy, actively exploring more effective therapeutic targets, and developing combination therapy strategies. Here, we review the key challenges that have emerged in the era of CIT and the possible solutions or development directions to overcome these difficulties, providing relevant references for basic research and the development of modified clinical treatment regimens.

ABSTRACT

Surgical resection (SR) is recommended as a radical procedure in the treatment of hepatocellular carcinoma (HCC). However, postoperative recurrence negatively affects the long-term efficacy of SR, and preoperative adjuvant therapy has therefore become a research hotspot. Some clinicians adopt transcatheter arterial chemoembolization (TACE) as a preoperative adjuvant therapy in patients undergoing SR to increase the resection rate, reduce tumor recurrence, and improve the prognosis. However, the findings of the most relevant studies remain controversial. Some studies have confirmed that preoperative TACE cannot improve the long-term survival rate of patients with HCC and might even negatively affect the resection rate. Which factors influence the efficacy of preoperative TACE combined with SR is a topic worthy of investigation. In this review, existing clinical studies were analyzed with a particular focus on several topics: screening of the subgroups of patients most likely to benefit from preoperative TACE, exploration of the optimal treatment regimen of preoperative TACE, and determination of the extent of tumor necrosis as the deciding prognostic factor.

ABSTRACT

Abstract Objective The aim of the present study was to determine the effect of combined zoledronic acid and alendronate therapy on bone edema and knee pain in cases of spontaneous osteonecrosis of the knee. We report our experience with this treatment. Methods A retrospective case series of 11 patients with spontaneous osteonecrosis of the knee confirmed by magnetic resonance image (MRI). The patients were treated with a single dose of 5 mg of intravenous zoledronic acid combined with 35 mg twice a week of oral alendronate, for 16 weeks. The visual analogue scale scores were noted before the beginning of the therapy, at 8 weeks, and at 16 weeks of follow-up. The size of the bone marrow edema adjacent to the lesion was measured on T2-weighted MRI coronal images at the beginning of the therapy and at 16 weeks. Results The average visual analogue scale score at 0 weeks was of 7.72, and of 0.81 at 16 weeks of therapy; the difference was statistically significant (p= 0.03). The mean bone marrow involvement at 0 weeks was of 80%, which reduced to 11.81% at 16 weeks of therapy. This change was statistically significant (p= 0.03). Conclusion Our data shows that the combination therapy causes early pain relief and reduction of the bone edema, and it is safe, effective and well-tolerated for a painful disease entity like spontaneous osteonecrosis of the knee.
