Objective: To evaluate the efficacy of neoadjuvant chemotherapy (NACT) in the treatment of locally advanced olfactory neuroblastoma (ONB), and to explore the factors related to the efficacy of NACT. Methods: A total of 25 patients with ONB who underwent NACT in Beijing TongRen Hospital from April 2017 to July 2022 were retrospectively analyzed. There were 16 males and 9 females, with an average age of 44.9 years (ranged 26-72 years). There were 22 cases of Kadish stage C and 3 cases of stage D. After multiple disciplinary team(MDT) discussion, all patients were treated sequentially with NACT-surgery-radiotherapy. Among them, 17 cases were treated with taxol, cis-platinum and etoposide (TEP), 4 cases with taxol, nedaplatin and ifosfamide (TPI), 3 cases with TP, while 1 case with EP. SPSS 25.0 software was used for statistical analysis, and survival analyses were calculated based on the Kaplan-Meier method. Results: The overall response rate of NACT was 32% (8/25). Subsequently, 21 patients underwent extended endoscopic surgery and 4 patients underwent combined cranial-nasal approach. Three patients with stage D disease underwent cervical lymph node dissection. All patients received postoperative radiotherapy. The mean follow-up time was 44.2 months (ranged 6-67 months). The 5-year overall survival rate was 100.0%, and the 5-year disease-free survival rates was 94.4%. Before NACT, Ki-67 index was 60% (50%, 90%), while Ki-67 index was 20% (3%, 30%) after chemotherapy [M (Q1, Q3)]. The change of Ki-67 before and after NACT was statistically significant (Z=-24.24, P<0.05). The effects of age, gender, history of surgery, Hyams grade, Ki-67 index and chemotherapy regimen to NACT were analyzed. Ki-67 index≥25% and high Hyams grade were related to the efficacy of NACT (all P<0.05). Conclusions: NACT could reduce Ki-67 index in ONBs. High Ki-67 index and Hyams grade are clinical indicators sensitive to the efficacy of NACT. NACT-surgery-radiotherapy is effective for patients with locally advanced ONB.

Durante los últimos años, la cirugía endoscópica transesfenoidal se ha convertido en el procedimiento quirúrgico de elección para el tratamiento de tumores hipofisarios. La técnica de abordaje actual es el resultado de una evolución histórica de vía por craneotomía a vía endonasal con ingreso a través del seno esfenoidal. Aunque la cirugía de tumores hipofisarios vía transesfenoidal endoscópica ha permitido disminuir las complicaciones graves asociadas a los abordajes externos, no estaÌ exenta de complicaciones, como la fístula de líquido cefalorraquídeo. A nivel del abordaje nasal, hay escasas descripciones de complicaciones y el compromiso del cartílago septal con deformidad en silla de montar no es una complicación documentada. Se presenta un caso de rinodeformidad en silla de montar poscirugía transesfenoidal de hipófisis en una paciente de 32 años a quien se le practicó una reconstrucción nasal con cartílago costal autólogo. En nuestra búsqueda bibliográfica es el primer caso registrado en Iberolatinoamérica
In recent years, transsphenoidal endoscopic surgery has become the surgical procedure of choice for the treatment of pituitary tumors. The current approach technique is the result of an historical evolution from craniotomy surgery to an endonasal procedure with entry through the sphenoid sinus. Although endoscopic transsphenoidal surgery has made it possible to reduce serious complications associated with external approaches, it is not without complications, such as cerebrospinal fluid fistula. At the level of the nasal approach, there are few descriptions of complications and involvement of the septal cartilage with saddle deformity is not a documented complication. We present a case of saddle rhinodeformity after transsphenoidal pituitary surgery in a 32-year-old patient who underwent nasal reconstruction with autologous costal cartilage. In our bibliographic search, it is the first case registered in IberoLatin America.

Objective: To summarize the preliminary experience in the treatment of esthesioneuroblastoma (ENB) and to explore the effect of age, chemotherapy, modified Kadish stage and pathological grade on the prognosis of ENB. Methods: The clinical data of 87 ENB patients from the First Affiliated Hospital of Sun Yat-sen University and Sun Yat-sen University Cancer Center between June 2002 and November 2017 were retrospectively analyzed. The modified Kadish stage was used to evaluate the extent of the lesions, and the Hyams grading system was used for pathological grading. The patients were followed up regularly to evaluate the recurrence and metastasis of the tumor. Cox proportional hazard model was used for univariate and multivariate analyses. Prognostic factors with P<0.05 in univariate analysis were included in multivariate analysis. After controlling the confounding factors, the model coefficients were used to calculate the hazard ratio (HR) and 95% confidence interval (CI). Results: The median follow-up time of ENB patients was 29 months, and the 5-year overall survival rate was 39.3%. In univariate analysis, age, chemotherapy, modified Kadish stage and pathology grade were independent predictors of overall survival, while gender, radiotherapy and surgery were not prognostic factors. Multivariate analysis showed that modified Kadish stage and pathology grade were independent predictors of overall survival rate after excluding confounding factors. Conclusions: Age, chemotherapy, modified Kadish stage and pathological grade are taking important role in the overall survival rate of patients with ENB. Modified Kadish stage and pathological grade are independent predictors of overall survival rate.

RESUMEN El linfoma nasal de células T/NK es una neoplasia agresiva, infrecuente, con predilección por el sexo masculino. Representa el 1,5% del total de linfomas no Hodgkin, el grupo etáreo más afectado es entre 40 a 80 años. Su etiología es desconocida, pero se ha asociado con el virus de Epstein Barr. Se presenta el caso de una paciente mujer de 40 años, con dolor e induración de fosa nasal derecha asociado a secreción fétida, seropurulenta de 3 meses de evolución. Estudio histopatológico, reporta linfoma nasal de células T/NK. La paciente recibe quimioterapia, con mejoría clínica sustancial. El linfoma T/NK es una neoplasia con sintomatologia inespecífica, predominio que afecta nasofaringe, amígdalas y base de la lengua. Entre las manifestaciones encontramos dolor de garganta, obstrucción nasal, rinorrea, epistaxis y cefalea. El diagnóstico se sospecha con imágenes, pero es necesaria la confirmación histológica con marcadores de inmunohistoquímica CD45Ro, CD43, CD3, CD2, CD45Ro entre otros. Muchos casos suelen detectarse en fase tardía, cuando ya son evidentes los signos radiológicos de destrucción ósea. El diagnóstico diferencial incluye lesiones infecciosas o inflamatorias, la bola fúngica fue el diagnóstico inicial realizado en esta paciente. El tratamiento suele realizarse con radioterapia y quimioterapia.
ABSTRACT Nasal T-cell / NK lymphoma is an uncommon aggressive neoplasm with male predilection. It represents 1.5% of the total number of non-Hodgkin's lymphomas, the most affected age group is 40-80 years. Its etiology is unknown but has been associated with the Epstein Barr virus. We present the case of a female patient of 40 years, with pain and induration of the right nostril associated with fetid secretion, seropurulent of 3 months of evolution. Histopathological study, reports T-cell / NK nasal lymphoma. The patient receives chemotherapy, with substantial clinical improvement. T / NK lymphoma is a neoplasm with predominant non-specific symptomatology, affecting the nasopharynx, tonsils and base of the tongue. Among the manifestations we find sore throat, nasal obstruction, rhinorrhea, epistaxis and headache. Diagnosis is suspected with imaging, but histological confirmation with immunohistochemical markers CD45Ro, CD43, CD3, CD2, CD45Ro, among others is required. Many cases are usually detected in the late phase, when radiological signs of bone destruction are already visible. The differential diagnosis includes infectious or inflammatory lesions, the fungal ball was the initial diagnosis made in this patient. Treatment is usually done with radiotherapy and chemotherapy.

In the early twentieth century, Argentina began legislating occupational safety. Law no.9.688 legislated accidents in the workplace (1915) and granted legal jurisdiction to work-related problems. The approval of this legislation was in dialogue with proposals being produced in other regions. The links established between local figures and colleagues elsewhere are useful for examining the circulation, reception and legitimation of knowledge on a regional scale. The objective of this article is to examine the transnational references in local discussions about occupational accidents in Peru and Chile during the first half of the twentieth century.
A partir del siglo XX, se inició en la Argentina la legislación protectora del trabajo. La ley n.9.688 legisló sobre accidentes de trabajo (1915) y otorgó jurisdicción legal a los problemas relativos al trabajo. La sanción de este corpus estuvo en diálogo con las propuestas que se producían en otras latitudes. Los vínculos que se establecieron entre los referentes locales y sus colegas son de utilidad para abordar el estudio de circulación, recepción y legitimación de los saberes dentro de una escala regional. Así pues, el objetivo de este trabajo es revisar las referencias transnacionales en las discusiones locales sobre los accidentes laborales en Perú y Chile durante la primera mitad del siglo XX.

INTRODUCTION: Extranodal NK/T-Cell lymphoma, nasal type (NKTLN) is a disease that mainly affects the nasal cavity and the paranasal sinuses. Early nasal symptoms are nonspecific, simulating sinus infection. With disease progression, necrosis of the nasal mucosa increases, hindering histological diagnosis. Thus, multiple biopsies may be necessary until definitive diagnosis. Most studies on NKTLN address the hematological and immunological aspects of the disease. OBJECTIVES: To present data from a Brazilian quaternary hospital, with emphasis on the clinical aspects of the disease, and to correlate the findings with the most recent literature data. METHODS: Case study of seven patient files. RESULTS: Patients were evaluated on their medical history, number of biopsies necessary, association with Epstein-Barr virus, treatment, and outcome. All patients had nonspecific nasal complaints and underwent at least three cycles of antibiotic therapy. The earlier a biopsy was performed, the fewer biopsies were required to diagnose the disease and start treatment. However, this fact did not translate into better prognosis. CONCLUSION: The otolaryngologist plays a fundamental role in the prognosis of NKTLN and can shorten time between symptom onset and treatment of the patient. .
INTRODUÇÃO: O linfoma extranodal de células NK/T tipo nasal (LNKTN) é uma doença que acomete preferencialmente a cavidade nasal e os seios paranasais. Os sintomas nasais iniciais são inespecíficos, mimetizando um quadro de infecção nasossinusal. Com a progressão da doença, aumenta a necrose da mucosa nasossinusal, dificultando o diagnóstico histológico e podendo ser necessárias múltiplas biópsias até o diagnóstico definitivo. A maioria dos estudos sobre o LNKTN aborda aspectos imunológicos e hematológicos da doença. OBJETIVO: Apresentar a casuística de um hospital quaternário brasileiro, destacando os aspectos clínicos dos pacientes e correlacionando aos achados mais recentes da literatura. MÉTODO: Estudo de casos de sete pacientes. RESULTADOS: Pacientes foram avaliados quanto a aspectos de sua história clínica, número de biópsias necessárias, associação ao EBV, tratamento e evolução. Todos iniciaram o quadro com queixas inespecíficas nasais e foram submetidos a pelo menos três ciclos de antibióticos. Quanto mais precocemente a biópsia foi realizada, menos biópsias foram necessárias para se obter o diagnóstico e iniciar o tratamento. Entretanto, esta situação não refletiu num melhor prognóstico dos pacientes. CONCLUSÃO: O otorrinolaringologista tem papel fundamental no prognóstico do LNKTN, podendo encurtar o tempo entre o início dos sintomas e o tratamento do paciente. .

Teratocarcinosarcoma rinosinusal es una neoplasia maligna infrecuente y rara, que combina elementos de teratoma y carcinosarcoma. Se compone de epitelio benigno o maligno (fibroblastos), mesénquima (cartílago, hueso o músculo liso) y elementos neurales. Hasta el año 2008 se han reportado un total de 63 casos de ubicación rinosinusal. Presentamos el caso de un teratocarcinosarcoma de fosa nasal, en un hombre de 67 años de edad, que consultó por obstrucción nasal rápidamente progresiva. La lesión se resecó completamente por abordaje endoscópico. El diagnóstico fue confirmado por histopatología e inmunohistoquímica. Se realizó tratamiento complementario con radioterapia, sin evidencia de recidiva al año después de la cirugía.
Rhinosinusal teratocarcinosarcoma is a rare malignant neoplasm, which combines teratoma and carcinoma elements. It is composed of benign or malignant epithelium (fibroblasts), mesenchymatic (cartilage, bone or smooth muscle) and neural elements. Until 2008, a total of 63 cases of rhinosinusal location have been reponed. We present the case of a nasal cavity teratocarcinosarcoma ín a 67 year old man that presented with rapidly progressing nasal obstruction. The lesion was completely resected by endoscopic approach. Diagnosis was confirmed by histological pathology and immunohistochemistry Additional treatment by radiotherapy was administered, with no evidence of recurrences a year after surgery.

La nariz juego un rol importante tanto estético como funcional. Ambos conceptos deben tomarse en cuenta a la hora de planear la reconstrucción nasal. Asimismo, deben evaluarse las características del defecto. En primer lugar debe definirse su localización siguiendo, para esto, los lineamientos de las subunidades estéticas propuestas por Burguet. En segundo lugar, se define su profundidad, dividiendo a estos defectos en superficiales, que son aquellos que respetan el periostiopericondrio siendo necesario en estos casos el aporte de cobertura cutánea; y profundos, cuando sobrepasan dichas estructuras, debiendo restituirse mucosa, esqueleto y cobertura cutánea. Se analizan tres casos clínicos con defectos superficiales de diversa complejidad que fueron resueltos con distintos colgajos.
