Evaluación de la experiencia de telemedicina en consulta de Cirugía de cabeza y cuello en un centro de referencia en Manizales / Evaluation of telemedicine experience in head and neck surgery consultation in a referral center in Manizales

Introducción. La infección por COVID-19 afectó drásticamente la atención en salud a nivel mundial, generando retos para la atención primaria. En orden de mitigar y manejar el contagio, la telemedicina se convirtió en una modalidad emergente y efectiva en varias especialidades médicas, incluida la cirugía de cabeza y cuello. Métodos. Estudio de corte transversal con análisis retrospectivo de pacientes atendidos en la consulta virtual durante 18 meses. Se estimaron frecuencias absolutas y relativas, y bivariado con regresión logística binaria. Se incluyeron las variables de diagnóstico primario, poder resolutivo de la consulta, necesidad de cita presencial, plataforma y dificultades de la misma. Resultados. Se incluyeron 2485 pacientes provenientes de 11 departamentos. La patología tiroidea fue la más frecuente (62,9 %), seguida de la aerodigestiva (10,9 %). La consulta fue eficiente en el 99 % de los casos, con una capacidad resolutiva del 96,4 %. El 1,4 % tuvo dificultades en la plataforma y el 8,3 % de los pacientes requirió cita presencial. Cuando hubo dificultad para la revisión de exámenes o una inadecuada inspección funcional, fue 30 veces más probable no poder resolver eficientemente la consulta. Conclusión. La telemedicina provee una alternativa eficiente de atención en cirugía de cabeza y cuello, especialmente en los controles de patología tiroidea, evitando desplazamientos innecesarios. En el tracto aerodigestivo, donde el examen físico es primordial, su utilidad está limitada a la posibilidad de realizar un examen endoscópico posterior que permita una adecuada estadificación y facilite la valoración presencial.

Introduction. The COVID-19 infection drastically affected health care worldwide, creating challenges for primary care. In order to mitigate and manage infection, telemedicine has become an emerging and effective modality in several medical specialties, including head and neck surgery. Methods. Retrospective cross-sectional analysis of patients seen in virtual consultation over 18 months. Absolute and relative frequencies were estimated, univariate analysis was done with chi-square, and bivariate analysis with binary logistic regression. Variables such as primary diagnosis, the resolution power of the consultation, the need for an in-person appointment, the platform, and its difficulties were included. Results. 2485 patients from 11 departments were included. Thyroid pathology was the most frequent (62.9%), followed by aerodigestive tract pathology (10.8%). The consultation was efficient in 99% of cases, with a resolution capacity of 96.4%. 1.4% had difficulties on the platform and 8.3% of patients required an in-person. When there was difficulty in reviewing exams or an inadequate functional inspection, it was 30 times more likely to not be able to efficiently be resolved. Conclusion. Telemedicine provides an efficient alternative for care in head and neck surgery, especially in thyroid pathology controls, avoiding unnecessary travel. In the aerodigestive tract, where the physical examination is essential, its usefulness is limited to the possibility of performing a subsequent endoscopic examination that allows adequate staging and facilitates in-person assessment.

Anatomical Diversity in Femur bones: Understanding the Morphological Variability for Surgical and Prosthetic Applications / Diversidad Anatómica en Huesos Fémur: Comprensión de la Variabilidad Morfológica para Aplicaciones Quirúrgicas y Protésicas

SUMMARY: The femur, the body's longest bone, plays a critical role in orthopaedics and radiology. Understanding its anatomy, particularly the neck-shaft angle (NSA), is vital for diagnosing bone issues and designing hip implants. While some Asian populations' femur measurements have been studied, there is a research gap concerning Sri Lankans. This study aimed to fill this gap by examining the proximal femur's anatomy in the Sri Lankan population. We analysed 45 adult human femurs (26 right, 19 left) of unknown sex, ethically sourced from the University of Sri Jayewardenepura. Femurs with fractures or pathologies were excluded. Precise measurements were recorded using digital vernier callipers, with millimetre accuracy. Parameters included mean femoral length, vertical and transverse femoral head diameters, neck axis and neck length. Each measurement was taken three times to minimize subjectivity. Right femurs had a mean length of 42.8 mm (SD±2.64), while left femurs measured 43.53 mm (SD±3.27). Mean NSA was 125.78º (SD±4.45) for left femurs and 127.59º (SD±2.06) for right. Mean femoral head diameters were 4.09mm (SD±0.30) (right) and 4.12mm (SD±0.31) (left). Mean anterior neck lengths of the right and left were 2.61 (SD±0.54) and 2.71(SD±0.50) respectively. Comparing our findings with other Asian populations highlighted significant variations in femur measurements. These discrepancies emphasize the need for population-specific data for orthopaedic interventions and raise questions about the suitability of imported prosthetics. Differences in femur length, neck length, and NSA between sides suggest potential challenges in using implants designed for one side on the other. This study underscores the necessity of population-specific data in orthopaedics, as femur measurements differ even among Asian populations. Further research and statistical analysis are essential for tailoring orthopaedic solutions to individual populations. The findings also suggest a potential need for locally manufactured prosthetics to better suit the Sri Lankan population.

El fémur, el hueso más largo del cuerpo, desempeña un papel fundamental en ortopedia y radiología. Comprender su anatomía, en particular el ángulo cuello-diáfisis (NSA), es vital para diagnosticar problemas óseos y diseñar implantes de cadera. Si bien se han estudiado las medidas del fémur de algunas poblaciones asiáticas, existe un vacío en la investigación sobre los habitantes de Sri Lanka. Este estudio tuvo como objetivo examinar la anatomía del fémur proximal en la población de Sri Lanka. Analizamos 45 fémures humanos adultos (26 derechos, 19 izquierdos) de sexo desconocido, obtenidos éticamente de la Universidad de Sri Jayewardenepura. Se excluyeron fémures con fracturas o patologías. Se registraron mediciones precisas utilizando calibradores vernier digitales, con precisión milimétrica. Los parámetros incluyeron la longitud femoral media, los diámetros vertical y transversal de la cabeza femoral, el eje del cuello y la longitud del cuello. Cada medición se tomó tres veces para minimizar la subjetividad. Los fémures derechos tuvieron una longitud media de 42,8 mm (DE ± 2,64), mientras que los fémures izquierdos midieron 43,53 mm (DE ± 3,27). La NSA media fue de 125,78º (DE±4,45) para el fémur izquierdo y de 127,59º (DE±2,06) para el derecho. Los diámetros medios de la cabeza femoral fueron 4,09 mm (DE ± 0,30) (derecha) y 4,12 mm (DE ± 0,31) (izquierda). Las longitudes medias del cuello anterior de la derecha y la izquierda fueron 2,61 (DE ± 0,54) y 2,71 (DE ± 0,50) respectivamente. La comparación de nuestros hallazgos con otras poblaciones asiáticas destacó variaciones significativas en las medidas del fémur. Estas discrepancias enfatizan la necesidad de datos específicos de la población para las intervenciones ortopédicas y plantean dudas sobre la idoneidad de las prótesis importadas. Las diferencias en la longitud del fémur, la longitud del cuello y la NSA entre lados sugieren posibles desafíos al utilizar implantes diseñados para un lado en el otro. Este estudio subraya la necesidad de datos específicos de la población en ortopedia, ya que las mediciones del fémur difieren incluso entre las poblaciones asiáticas. Es esencial realizar más investigaciones y análisis estadísticos para adaptar las soluciones ortopédicas a poblaciones individuales. Los hallazgos también sugieren una posible necesidad de prótesis fabricadas localmente para adaptarse mejor a la población de Sri Lanka.

A Cocktail of Natural Compounds Holds Promise for New Immunotherapeutic Potential in Head and Neck Cancer / 中国结合医学杂志

OBJECTIVE@#To obtain detailed understanding on the gene regulation of natural compounds in altering prognosis of head and neck squamous cell carcinomas (HNSC).@*METHODS@#Gene expression data of HNSC samples and peripheral blood mononuclear cells (PBMCs) of HNSC patients were collected from Gene Expression Omnibus (GEO). Differential gene expression analysis of GEO datasets were achieved by the GEO2R tool. Common differentially expressed gerres (DEGs) were screened by comparing DEGs of HNSC with those of PBMCs. The combination was further analyzed for regulating pathways and biological processes that were affected.@*RESULTS@#Totally 110 DEGs were retrieved and identified to be involved in biological processes related to tumor regulation. Then 102 natural compounds were screened for a combination such that the expression of all 110 commonly DEGs was altered. A combination of salidroside, ginsenoside Rd, oridonin, britanin, and scutellarein was chosen. A multifaceted, multi-dimensional tumor regression was showed by altering autophagy, apoptosis, inhibiting cell proliferation, angiogenesis, metastasis and inflammatory cytokines production.@*CONCLUSIONS@#This study has helped develop a unique combination of natural compounds that will markedly reduce the propensity of development of drug resistance in tumors and immune evasion by tumors. The result is crucial to developing a combinatorial natural therapeutic cocktail with accentuated immunotherapeutic potential.

Advances in Head-and-Neck Interventional Radiotherapy (Brachytherapy)

@#Interventional radiotherapy, also known as brachytherapy, is the use of sealed radioactive sources that directly deliver radiation to the tumor or tumor bed. Its unique dose distribution profile allows for high conformality, making it a very useful modality in the treatment of cancers in the head and neck, where different organs and substructures that serve various but related functions are situated close to each other. In recent years, we have seen several important technological breakthroughs in the field, especially regarding its application in head and neck cancers. These include advances in treatment delivery, dosimetry planning , image guidance , and catheter positioning techniques . These innovations, which often require interdisciplinary interventions, have resulted in enhanced treatment accuracy, and therefore, major clinical advantages in terms of increased local control and decreased toxicity, as well as economic benefits. In order to highlight the differences from old brachytherapy techniques, a more appropriate terminology should perhaps be adopted, to signify these advancements that resulted in new opportunities, approaches and better outcomes – interventional radiotherapy (IRT). Such a change in terminology will not only allow recognition of these advances, but also a meaningful distinction from obsolete techniques and suboptimal outcomes that are associated with traditional brachytherapy. This is very important in increasing awareness among professionals outside the field of radiation oncology. We briefly review these recent advances, the current indications, and future directions for IRT in head-and-neck cancers.

Effect of suspension combined with acupuncture on chronic non-specific neck pain / 中国康复理论与实践

ObjectiveTo explore the effect of suspension combined with acupuncture on chronic non-specific neck pain (CNNP). MethodsA total of 81 patients with unilateral CNNP from the rehabilitation outpatient clinic of Wangjing Hospital from March, 2022 to March, 2023 were divided into suspension group (n = 27), acupuncture group ((n = 27) and combined group (n = 27) randomely. The suspension group underwent conventional suspension, the acupuncture group received conventional acupuncture treatment, and the combined group underwent suspension and acupuncture, for six weeks. The Visual Analogue Scale (VAS), Neck Disability Index (NDI), and cross-sectional area (CSA) of longus colli and multifidus in the neck using ultrasound imaging were compared before and after treatment. ResultsAfter treatment, the VAS and NDI score, and CSA of longus colli and multifidus improved in three groups (|t| > 4.473, P < 0.001), and the combined group was better than the other two groups (P < 0.05). ConclusionSuspension and acupuncture can relief the pain, improve function, and increase CSA of longus colli and multifidus in patients with unilateral CNNP, while the combination of the two methods is better.

Prevalence and Factors Associated with Shoulder Complex Function (SCF) Among the Elderly in Private Physiotherapy Clinic in Klang Valley, Malaysia

@#Introduction: Shoulder problems have been a challenge among the aging population. Although reports surfaced on factors affecting shoulder dysfunction, however, such studies in relation to other factors like neck pain (NP) factor are limited especially among the elderly in the urban population. This study investigated the prevalence and factors associated with shoulder complex dysfunction among the outpatient elderly attending private physiotherapy clinics. Methods: A total of 75 elderly aged ≥ 60 years old from four private physiotherapy clinics were recruited by simple random sampling method. The elderly were evaluated using the QuickDASH questionnaire to assess shoulder complex dysfunctions and NP scale. Results: A total of 92% of participants have shoulder complex dysfunction. A positive correlation of NP to shoulder complex dysfunction ( r (75) = 0.83, p<.001) with significant associations of sex ( z= -2.549, p=0.011), smoking ( z= -2.388, p=0.017), lifestyle ( z= -5.780, p=0.000), hypertension ( z= -2.808, p=0.005), osteoarthritis ( z= -2.966, p=0.003), and NP scale ( z= -2.173, p=0.031). The predicting factor of shoulder complex dysfunction is sex (β = 0.156, t (74) = 2.240, p= 0.028) and NP scale (β = 0.704, t (74) = 7.853, p= 0.000). Conclusion: There is a high prevalence of shoulder complex dysfunction among the outpatient elderly attending private physiotherapy clinics with a predicting associating factor of sex and NP.

Elective parotidectomy and neck dissection are not beneficial in cutaneous squamous cell carcinoma of the head

Abstract Objective Cutaneous Squamous Cell Carcinoma (cSCC), a tumor with a significantly increasing incidence, is mostly diagnosed in the head region, where tumors have a worse prognosis and a higher risk of metastases. The presence of metastases reduces specific five-year survival from 99% to 50%. As the risk of occult metastases does not exceed 10%, elective dissection of the tributary parotid and neck lymph nodes is not recommended. Methods We retrospectively analyzed a group of 12 patients with cSCC of the head after elective dissections of regional (parotid and cervical) nodes by means of superficial parotidectomy and selective neck dissection. Results We diagnosed occult metastases neither in the cervical nor parotid nodes in any patient. None were diagnosed as a regional recurrence during the follow-up period. Conclucion Our negative opinion on elective parotidectomy and neck dissection in cSCC of the head is in agreement with the majority of published studies. These elective procedures are not indicated even for tumors showing the presence of known (clinical and histological) risk factors for lymphogenic spread, as their positive predictive value is too low. Elective parotidectomy is individually considered as safe deep surgical margin. If elective parotidectomy is planned it should include only the superficial lobe. Completion parotidectomy and elective neck dissection are done in rare cases of histologically confirmed parotid metastasis in the parotid specimen. Preoperatively diagnosed parotid metastases without neck involvement are sent for total parotidectomy and elective selective neck dissection. Cases of clinically evident neck metastasis with no parotid involvement, are referred for comprehensive neck dissection and elective superficial parotidectomy. The treatment of concurrent parotid and cervical metastases includes total conservative parotidectomy and comprehensive neck dissection. Level of evidence How common is the problem?

Effectiveness and tolerance of electrochemotherapy as palliative therapy for patients with head and neck cancer and malignant melanoma and its relation to early skin reaction

Abstract Objectives To evaluate the efficacy and tolerance after the electrochemotherapy treatment for local therapy of cutaneous and subcutaneous metastases of head-and-neck tumors and malignant melanoma refractory to standard therapies, mainly in neck metastasis of squamous cell carcinoma. And, to evaluate the relation of this response according to the skin reaction (healing with ulcer or dry crust). Methods prospective pase II, observational clinical study of 56 patients with metastases of head-and-neck squamous cell carcinoma (n = 13), papillary thyroid carcinoma (n = 4), adenoid cystic carcinoma of parotid gland (n = 1) or malignant melanoma (n = 37, 5 in head). Patients were treated by electrochemotherapy (application of electrical pulses into the tumor) after the administration of a single intravenous dose of bleomycin. Kaplan-Meier curves were performed. The statistical significance was evaluated using log-rank test; p-value of less than 0.05 was considered as significant. Results Overall clinical response was observed in 47 patients (84%). Local side effects were mild in all the patients. Ten patients (76.9%) with neck metastasis of squamous cell carcinoma had some degree of response, but only in one was complete. Patients even with only partial response had a higher overall survival than patients without response (p = 0.02). Most of the patients with squamous cell carcinoma had diminution of pain and anxiety. Response rate and overall survival was higher in MM patients (86.5%) than in squamous cell cancer patients (76.9%) (p = 0.043). The healing process (dry crust/ulcer) was not associated with the overall survival (p = 0.86). Conclusions Electrochemotherapy is associated a higher overall survival and diminution of pain and anxiety. Therefore, it is an option as palliative treatment for patients with neck metastasis of squamous cell carcinoma refractory to other therapies or even as a concomitant treatment with newer immunotherapies. The type of healing of the surgical wound could not be associated with a higher rate of response or survival. Level of evidence III.

Multimodal analgesia versus patient-controlled analgesia in the management of acute postoperative spinal pain: systematic review and meta-analysis / Analgesia multimodal versus analgesia controlada pelo paciente no tratamento da dor aguda pós-operatória da coluna: revisão sistemática e meta-análise

ABSTRACT BACKGROUND AND OBJECTIVES: Spine diseases have a high annual prevalence and are the main causes of years lived with disability and chronic pain. Among the postoperative analgesic control options, patient-controlled analgesia (PCA) and multimodal analgesia (MMA) have shown good clinical results. This meta-analysis seeks new evidence to help in the treatment of acute postoperative pain in patients undergoing spinal surgery. CONTENTS: The following databases were used: Cochrane Central Register of Controlled Trials, Medline and Embase. Studies that compared two post-surgical analgesic interventions were included; MMA and PCA. The parameters evaluated were: analgesic effect; opioid consumption; length of hospital stay; and adverse effects. Registration of the systematic review protocol: (PROSPERO CRD42023446627). There was no statistical difference when assessing analgesic improvement comparing MMA to PCA (MD -0.12 [-0.41, 0.17] 95%CI with p=0.69). There was a statistical difference, with lower opioid consumption in MMA compared to PCA (MD -3.04 [-3.69, -2.39] 95%CI with p=0.0002). Statistically significant difference regarding length of hospital stay in favor of MMA (MD -13.17 [-16.98, -9.36] 95%CI with p=0.00001), and significantly lower incidence of nausea and vomiting in patients undergoing MMA in compared to PCA (OR 0.26 [0.11, -0.64] 95%CI with p=0.003). CONCLUSION: MMA was equivalent to PCA in the treatment of acute postoperative spinal pain, with the significant clinical advantage and safety of lower amounts of infused opioids, shorter hospital stay and lower incidence of adverse effects.

RESUMO JUSTIFICATIVA E OBJETIVOS: As doenças da coluna apresentam alta prevalência anual e são as principais causas de anos vividos com incapacidade e de cronificação da dor. Dentre as opções de controle analgésico pós-operatória, a analgesia controlada pelo paciente (ACP) e a analgesia multimodal (AMM) apresentam bons resultados clínicos. O objetivo deste estudo foi buscar novas evidências que auxiliem no tratamento da dor aguda no pós-operatório do paciente submetido à cirurgia da coluna. CONTEÚDO: As bases de dados utilizadas: Cochrane Central Register of Controlled Trials, Medline e Embase. Foram incluídos estudos que compararam duas intervenções analgésicas pós-cirúrgicas; AMM e ACP. Os parâmetros avaliados foram: efeito analgésico; consumo de opioide; tempo de internação hospitalar e efeitos adversos. Registro do protocolo de revisão sistemática: (PROSPERO CRD42023446627). Não houve diferença estatística quando avaliadas a melhora analgésica comparando a AMM à ACP (MD -0,12 [-0,41, 0,17] 95%CI com p=0,69). Houve diferença estatística, com menor consumo de opioide na AMM em comparação à ACP (MD -3,04 [-3,69, -2,39] 95%IC com p=0,0002). Diferença estatística significativa com relação ao tempo de permanência hospitalar a favor da AMM (MD -13,17 [-16,98, -9,36] 95%IC com p=0,00001), e incidência significativamente menor de náuseas e vômitos nos pacientes submetidos a AMM em comparação a ACP (OR 0,26 [0,11, -0,64] 95%IC com p=0,003). CONCLUSÃO: A AMM foi equivalente à ACP no tratamento da dor aguda pós-operatória da coluna, com a significativa vantagem clínica e a segurança de menores quantidades de opioides infundidos, menor tempo de internação hospitalar e menor incidência de efeitos adversos.

Malignant tumors affecting the head and neck region in ancient times: Comprehensive study of the CRAB Database

Abstract In the modern world, cancer is a growing cause of mortality, but archeological studies have shown that it is not exclusive to modern populations. The aim of this study is to examine the epidemiologic, social, and clinicopathologic features of head and neck cancers in ancient populations. To do this, we extracted all records that described malignant lesions in the head and neck region available in the Cancer Research in Ancient Bodies Database (CRAB). The estimated age, sex, physical condition of the remains (skeletonized, mummified), anatomic location of tumors, geographic location, chronology, tumor type, and methods of tumor diagnosis were collected. One hundred and sixty-seven cases were found, mostly originating from Europe (51.5%). Most records were of adults between 35 and 49 years of age (37.7%). The most involved site was the skullcap (60.4%), and the most common malignancies were metastases to the bone (65.3%) and multiple myeloma (17.4%). No primary soft tissue malignancies were registered. The results of our study indicate that head and neck cancers were present in ancient civilizations, at least since 500,000 BCE. The available data can help to improve the current understanding of the global distribution of head and neck cancer and its multidimensional impacts on populations in the contemporary world.

Cut-off points of neck and waist circumference as predictors of obstructive sleep apnea in the Colombian population: a comparison with polysomnography

ABSTRACT BACKGROUND: Neck circumference (NC) is a useful anthropometric measure for predicting obstructive sleep apnea (OSA). Ethnicity and sex also influence obesity phenotypes. NC cut-offs for defining OSA have not been established for the Latin American population. OBJECTIVES: To evaluate NC, waist circumference (WC), and body mass index (BMI) as predictors of OSA in the Colombian population and to determine optimal cut-off points. DESIGN AND SETTING: Diagnostic tests were conducted at the Javeriana University, Bogota. METHODS: Adults from three cities in Colombia were included. NC, WC, and BMI were measured, and a polysomnogram provided the reference standard. The discrimination capacity and best cut-off points for diagnosing OSA were calculated. RESULTS: 964 patients were included (57.7% men; median age, 58 years) and 43.4% had OSA. The discrimination capacity of NC was similar for men and women (area under curve, AUC 0.63 versus 0.66, P = 0.39) but better for women under 60 years old (AUC 0.69 versus 0.57, P < 0.05). WC had better discrimination capacity for women (AUC 0.69 versus 0.57, P < 0.001). There were no significant differences in BMI. Optimal NC cut-off points were 36.5 cm for women (sensitivity [S]: 71.7%, specificity [E]: 55.3%) and 41 cm for men (S: 56%, E: 62%); and for WC, 97 cm for women (S: 65%, E: 69%) and 99 cm for men (S: 53%, E: 58%). CONCLUSIONS: NC and WC have moderate discrimination capacities for diagnosing OSA. The cut-off values suggest differences between Latin- and North American as well as Asian populations.

Methods: A cross-sectional descriptive study was carried out in the María Curie Oncological Teaching Provincial Hospital of Camagüey province in a universe of 218 patients, who attended the Head and Neck Surgery Service from 2018 to 2022 and had oral cancer as diagnosis. The sample was limited to 113 patients who met the inclusion and exclusion criteria. Results: Oral cancer predominated in the male sex with 89 (78.76 percent) in the years 2019 and 2021. There was a higher incidence in patients with white skin with 97 (85.84 percent) and the year 2021 showed a higher number of these patients. The tongue was the most affected with 43 (30.05 percent) patients, followed by the floor of the mouth in 18 (15.92 percent) and the gums in 17 (15.04 percent) patients. According to stage there was a predominance of stage IV in 61 (53.98 percent) patients, followed by stage III with 18.58 percent of patients diagnosed. Conclusions: Male sex prevailed in the 60 to 79 years age group and white skin patients were the most affected. The location of the lesions manifested with greater incidence on the tongue and stages IV and III of the disease are the most representative at the time of diagnosis(AU)

Programa de acompañamiento a personas diagnosticadas con cáncer de cabeza y cuello, liderado por la enfermera de práctica avanzada con mención en oncología / Support program for people with head and neck cancer, led by an oncology advanced practice nurse

Se presenta una propuesta de intervención de enfermería de práctica avanzada (EPA) en oncología. OBJETIVO: Implementar un programa de acompañamiento para pacientes con cáncer de cabeza y cuello. PROPUESTA: Realizar un levantamiento del proceso y descripción del flujo que debe transitar el paciente oncológico desde la sospecha, diagnóstico, tratamiento, seguimiento y derivación a cuidados paliativos. En segunda instancia, crear e implementar una consulta de enfermería que pueda responder a las necesidades de atención de salud en forma holística de la persona con diagnóstico oncológico de cáncer de cabeza y cuello, tanto en las personas que se encuentran en fase sospecha y confirmación diagnóstica (consulta de ingreso) y en el proceso de seguimiento del sobreviviente (después de finalizado el tratamiento oncológico), a través de una puesta en marcha escalonada, con períodos de evaluación en cada uno de ellos. CONCLUSIONES: La heterogeneidad de la persona diagnosticada con cáncer de cabeza y cuello representa un desafío y se considera a la EPA un profesional para manejar casos complejos. El camino hacia este nuevo rol será paulatino, y requiere una transición tanto por el equipo de salud, los pacientes y las propias enfermeras dentro del marco legal vigente.

This paper presents a proposal for an advanced practice nursing intervention (APN) in oncology. OBJECTIVE: To implement a support program for patients with head and neck cancer. PROPOSAL: To carry out a survey of the process and description of the flow that the oncology patient must go through from suspicion, diagnosis, treatment, follow-up and referral to palliative care. Secondly, to create and implement a nursing consultation that can respond to the health care needs in a holistic manner of the person with an oncological diagnosis of head and neck cancer, both in people who are in the suspicion and diagnostic confirmation phase (admission consultation) and in the follow-up process of the survivor (after the end of oncological treatment), through a staggered implementation, with evaluation periods in each of them. CONCLUSIONS: The heterogeneity of the person diagnosed with head and neck cancer represents a challenge and the APN is considered a professional to manage complex cases. The journey towards this new role will be gradual, and requires a transition both by the health team, the patients and the nurses themselves within the current legal framework.

Caracterización de marcadores de células madre tumorales en cáncer escamocelular de cavidad oral

Introducción: El cáncer escamocelular de cavidad oral es una patología con bajas tasas de sobrevivencia. Cuando no es tratado adecuadamente es un tumor de alta recurrencia y resistente al tratamiento. Nuevas hipótesis plantean que las células tumorales progenitoras por sus propiedades de auto renovación, iniciación tumoral, migración y metástasis pueden ser responsables de la manutención y renovación de este tumor. Sin embargo, aún no existe un consenso sobre la verdadera participación de ellas, debido a que su identificación y caracterización es aún un reto experimental. Objetivo: En este trabajo se busca detectar células con expresión de marcadores de células tumorales Progenitoras en muestras cáncer escamocelular de cavidad oral y relacionarlo con los estadios de diferenciación del tumor. Metodología: En esta investigación se tomaron 32 muestras de pacientes con carcinoma escamocelular de cavidad oral. Se logró detectar in situ, mediante la técnica de inmunofluorescencia, cuatro reconocidos marcadores de células tumorales progenitoras. Resultados: Se identificaron los marcadores OCT4, SSEA4, NANOG y TRA-1-60 en los diferentes estadios de diferenciación tumoral, lo que sugiere la participación de las células progenitoras tumorales en la evolución de esta patología. Conclusiones: El establecimiento y correcta identificación de las células tumorales progenitoras abre nuevas vías terapéuticas para el abordaje de este tumor, en busca de mejorar el pronóstico, tasa de sobrevivencia y calidad de vida del paciente.

Introduction: Squamous cell carcinoma of the oral cavity is a pathology with poor survival rates. When it is not adequately treated, it is a tumor with high recurrence and resistance to treatment. According to new hypotheses, progenitor tumor cells, due to their properties of self-renewal, tumor initiation, migration, and metastasis, could be responsible for the maintenance and renewal of this tumor. However, there is still no consensus on their true participation, subsequent to difficult in their identification and characterization. Materials and methods: In this research, 32 samples provided from patients diagnosis with squamous cell carcinoma of the oral cavity were used. To detect specific markers progenitor tumor cells were used immunofluorescence microscopy. Results: The cells markers OCT4, SSEA4, NANOG and TRA-1-60 were identified in the different stages of the tumor samples, all these findings suggest the role of tumor progenitor cells in the evolution of this pathology. Conclusions: The establishment and correct identification of the progenitor tumor cells provide new therapeutic options for the approach of this tumor seeking to improve the prognosis, survival rate and quality of life of the patient.

Retalho supraclavicular para reconstrução oncológica em cabeça e pescoço: Uma série de 62 casos / Supraclavicular flap for head and neck oncological reconstruction: A series of 62 cases

Introdução: A reconstrução oncológica de defeitos extensos em cabeça e pescoço impõe ao cirurgião plástico a difícil decisão entre o uso de retalhos livres e retalhos pediculados. O retalho supraclavicular é um dos principais exemplos de retalho pediculado, sendo versátil, com espessura delgada e cor semelhante à região a ser reconstruída. Método: Um estudo retrospectivo foi realizado através da coleta de dados de prontuário de pacientes internados no Instituto do Câncer do Estado de São Paulo, entre dezembro de 2010 e março de 2020. Resultados: Dentre os 62 pacientes reconstruídos com retalho supraclavicular, 37 eram do sexo masculino e 25 do sexo feminino. Cinquenta e oito pacientes (93,5%) possuíam alguma comorbidade associada. Ao todo, 27 complicações relacionadas ao retalho (43,5%) foram registradas, sendo 5 necroses totais (8%). Conclusão: O retalho supraclavicular possui importante papel nas reconstruções oncológicas de cabeça e pescoço e deve ser considerado como opção em pacientes maus candidatos a retalhos microcirúrgicos.

Introduction: The oncological reconstruction of extensive defects in the head and neck requires the plastic surgeon to make a difficult decision between the use of free flaps and pedicled flaps. The supraclavicular flap is one of the main examples of a pedicled flap, being versatile, with a thin thickness and similar color to the region to be reconstructed. Method: A retrospective study was carried out by collecting data from medical records of patients admitted to the Cancer Institute of the State of São Paulo between December 2010 and March 2020. Results: Among the 62 patients reconstructed with a supraclavicular flap, 37 were male and 25 female. Fifty-eight patients (93.5%) had some associated comorbidity. In total, 27 complications related to the flap (43.5%) were recorded, 5 of which were total necrosis (8%). Conclusion: The supraclavicular flap plays an important role in head and neck oncological reconstructions and should be considered as an option in patients who are poor candidates for microsurgical flaps.

Uso de dispositivos móviles y alteraciones cervicales en estudiantes universitarios / Use of mobile devices and cervical disorders in university students / Uso de dispositivos móveis e distúrbios cervicais em estudantes universitários

Las alteraciones cervicales son un problema multifactorial que afecta a la sociedad moderna. Posturas viciosas, traumatismos y defectos congénitos relacionados con la columna cervical pueden desarrollar inestabilidad, pinzamiento radicular, cervicoartrosis y cervicalgias. Objetivo. Relacionar el uso de dispositivos móviles con las alteraciones cervicales en estudiantes universitarios. Materiales y métodos. Estudio descriptivo, observacional, que se realizó entre los meses de mayo y julio del 2023, cuya muestra fue de 172 estudiantes universitarios que se obtuvo aplicando la fórmula para el cálculo muestral de poblaciones conocidas, mediante un muestreo no probabilístico. Se utilizó el test goniométrico para medir el rango articular, el test postural para identificar las alteraciones posturales, la técnica de palpación para identificar dolor inespecífico, prueba de resistencia para los músculos flexores (NFMET) y extensores (NEET), por último, se realizó la prueba de Spurling para identificar casos de radiculopatías. Resultados. Aunque las relaciones estadísticas no fueron consistentes, se observó que quienes utilizaron más tiempo los teléfonos celulares (87,0%) mostraron más limitaciones cervicales que los usuarios menos frecuentes (73,5%). La movilidad articular fue limitada en el 84,3% de la población, especialmente en varones (93,5%); la resistencia muscular normal en extensión fue más prevalente en el caso de los hombres (84,9%), mientras que la resistencia alterada en flexión fue más prevalente en mujeres (94,9%). Conclusiones. Según los resultados obtenidos en esta investigación, no se encontró suficiente evidencia para determinar una relación estadísticamente significativa (P˃0,05) entre las alteraciones cervicales y el uso de teléfonos celulares, aunque se observó una mayor limitación en el caso de quienes más tiempo utilizaban el dispositivo móvil.

Cervical disorders are a multifactorial problem affecting modern society. Vicious postures, trauma and congenital defects related to the cervical spine can develop instability, radicular impingement, cervicoarthrosis and cervicalgia. Objective. To relate the use of mobile devices with cervical disorders in university students. Materials and methods. Descriptive, observational study carried out between May and July 2023, with a sample of 172 university students obtained by applying the formula for the sample calculation of known populations, by means of non-probabilistic sampling. The goniometric test was used to measure joint range, the postural test to identify postural alterations, the palpation technique to identify non-specific pain, resistance test for flexor (NFMET) and extensor (NEET) muscles, and finally, the Spurling test was performed to identify cases of radiculopathy. Results. Although the statistical relationships were not consistent, it was observed that those who used cell phones longer (87.0%) showed more cervical limitations than less frequent users (73.5%). Joint mobility was limited in 84.3% of the population, especially in men (93.5%); normal muscular endurance in extension was more prevalent in men (84.9%), while impaired endurance in flexion was more prevalent in women (94.9%). Conclusions. According to the results obtained in this investigation, there was not enough evidence to determine a statistically significant relationship (P˃0.05) between cervical alterations and cell phone use, although a greater limitation was observed in the case of those who used the mobile device the longest.
