Adult Normative Data for the OMNI-Vocal Effort Scale (VES).

PURPOSE: To establish normative values for the OMNI-Vocal Effort Scale (VES) in healthy adults without voice complaints. Secondary objective is to determine if there are differences in perceived vocal effort across age groups and between sexes. STUDY DESIGN: Prospective data collection across groups. METHOD: A nine-item survey was administered by speech-language pathologists with specialization in voice to consenting adults 18 years or older. Participants underwent an auditory perceptual evaluation of voice and answered questions regarding age, history of voice problems, history of voice surgery, smoking history and hearing loss. Participants were instructed to rate their perceived vocal effort in conversational speech using the OMNI-VES. Multivariant analysis was conducted. RESULTS: Two hundred and fifty-one participants were recruited. The majority of adults without voice complaints reported that producing conversational voice was within the "extremely easy" to "easy" range, 0-3 (92.4%). CONCLUSIONS: This study provides preliminary data for perceived vocal effort. The OMNI-VES may be a useful tool in understanding changes in perceived vocal effort as a result of treatment for voice disorders. Further normative data are needed between sexes, across the gender spectrum, and older adult populations. Future directions include examining the magnitude of difference between numeric values on the scale and use of the scale with other dysphonic populations. LEVEL OF EVIDENCE: 3 Laryngoscope, 2024.

Ethanol ablation of papillary thyroid carcinoma nodal metastases: Long-term outcomes.

BACKGROUND: Percutaneous ethanol ablation has emerged as a treatment for recurrent papillary thyroid carcinoma in the lateral neck after compartment-oriented therapeutic lymphadenectomy. However, the safety and utility of percutaneous ethanol ablation as a primary treatment modality for lateral neck metastases remains undefined. We aimed to investigate long-term outcomes of percutaneous ethanol ablation of lateral neck papillary thyroid carcinoma recurrence both with and without prior lymphadenectomy. METHODS: We conducted a retrospective study of patients with lateral neck papillary thyroid carcinoma treated with percutaneous ethanol ablation from 2013 to 2018. Patient characteristics, disease volume, morbidity, and recurrence (development of new lymphadenopathy within a percutaneous ethanol ablation-treated nodal compartment) were assessed. RESULTS: We identified 117 patients who underwent percutaneous ethanol ablation for papillary thyroid carcinoma lateral neck metastases-67 (57%) had a prior lateral neck dissection. Median follow-up after percutaneous ethanol ablation was 5.5 years (interquartile range 3.1-7.5). On average, 1.4 lymph nodes (range: 1-6) were treated. Three patients (3%) developed transient nerve-related complications after percutaneous ethanol ablation. Of 15 patients who underwent lateral neck dissection after percutaneous ethanol ablation (including patients undergoing repeat lateral neck dissection), dissection was "difficult" in 8 (53%) (7 of whom had previously undergone lateral neck dissection), and 4 (27%) developed complications (transient nerve dysfunction = 3, lymphatic leak = 1). Thirty-three patients (28%) developed recurrent papillary thyroid carcinoma. No difference in recurrence was seen between patients who did or did not undergo pre-percutaneous ethanol ablation lateral neck dissection (no pre-percutaneous ethanol ablation lateral neck dissection: 24%, pre-percutaneous ethanol ablation lateral neck dissection, 31%; hazard ratio = 1.27, 95% confidence interval 0.62-2.58; P = .514). CONCLUSION: Percutaneous ethanol ablation may be a safe primary treatment modality for papillary thyroid carcinoma lateral neck nodal recurrence in selected patients with low-volume nodal disease.

[Translated article] Study of femoral component malrotation as a cause of pain after total knee arthroplasty.

INTRODUCTION: The total knee arthroplasty (TKA) has been shown to be a successful and cost-benefit procedure in terms of pain improvement in patient with symptomatic knee osteoarthritis. However, almost a 20% of the patients are not satisfied with the result of the surgery. MATERIAL AND METHOD: We have carried out a transversal unicentric cases controls study with clinical cases of the own hospital, obtained by a clinical records revision. A total of 160 patients with a TKA with at least 1 year of follow-up were selected. Demographic variables, functional scales (WOMAC and VAS) and rotation of the femoral component through the analysis of the images obtained by CT scan were collected. RESULTS: The total was 133 patients that was divided in two groups. A control group and pain group. The Control group was made up of 70 patients with a mean age of 69.59 years (23 men and 47 women) and the pain group was made up of 63 patients with a mean age of 69.48 years (13 men and 50 women). We didn't find difference regarding the analysis of the rotation of the femoral component. In addition, we were not found significant differences when applying a stratification by sex. And, the analysis of the malrotation of the femoral component, previously defining limits of value rotation considered as extreme, in any of the case did not show significant differences. CONCLUSION: The results of the study confirm that malrotation of the femoral component had no influence on the presence of pain at a minimum of one year of follow-up after TKA implantation.

Clinician feedback using a shared decision-making tool for the evaluation of patients with thyroid nodules-an observational study.

BACKGROUND: We pilot-tested an encounter conversation aid to support shared decision making (SDM) between patients with thyroid nodules and their clinicians. OBJECTIVE: Characterize the clinician feedback after providing care to patients with thyroid nodules using a tool to promote SDM conversations during the clinical encounter, and evaluate how clinicians used the tool during the visit. METHODS: Mixed method study in two academic centers in the U.S., including adult patients presenting for evaluation of thyroid nodules and their clinicians. We thematically analyzed interviews with clinicians after they used the SDM tool in at least three visits to characterize their feedback. Additionally, investigators evaluated visits recordings to determine the extent to which clinicians engaged patients in the decision-making process (OPTION score, scale 0 to 100, higher levels indicating higher involvement), the tool's components used (fidelity), and encounter duration. Using a post-visit survey, we evaluated the extent to which clinicians felt the tool was easy to use, helpful, and supportive of the patient-clinician collaboration. RESULTS: Thirteen clinicians participated in the study and used the SDM tool in the care of 53 patients. Clinicians thought the tool was well-organized and beneficial to patients and clinicians. Clinicians noticed a change in their routine with the use of the conversation aid and suggested it needed to be more flexible to better support varying conversations. The median OPTION score was 34, the fidelity of use 75%, and the median visit duration 17 min. In most encounters, clinicians agreed or strongly agreed the tool was easy to use (86%), helpful (65%), and supported collaboration (62%). CONCLUSION: Clinicians were able to use a SDM tool in the care of patients with thyroid nodules. Although they wished it were more flexible, they found on the whole that its use in the clinical encounter was beneficial to patients and clinicians.

Primary aldosteronism: Practical recommendations for treatment and follow-up.

Primary aldosteronism (PA) is the most common cause of secondary arterial hypertension. For unilateral cases, surgery offers the possibility of cure, with unilateral adrenalectomy being the treatment of choice, whereas bilateral forms of PA are treated mainly with mineralocorticoid receptor antagonists (MRA). The goals of treatment for PA due to either unilateral or bilateral adrenal disease include reversal of the adverse cardiovascular effects of hyperaldosteronism, normalization of serum potassium in patients with hypokalemia, and normalization of blood pressure. The Primary Aldosteronism Surgery Outcome group (PASO) published a study defining clinical and biochemical outcomes based on blood pressure and correction of hypokalemia and aldosterone to renin ratio (ARR) levels for patients undergoing total unilateral adrenalectomy for unilateral PA. In this review, we provide several practical recommendations for the medical and surgical management and follow-up of patients with PA.

Expression of enzymes involved in the urea cycle and muscle and mammary gland development of Holstein × Gyr heifers in a rotational grazing system supplemented with increasing protein levels.

Studies evaluating the crude protein (CP) supplementation strategies across the year for grazing cattle and its association with the enzymes involved in the urea cycle and muscle and mammary gland developments are scarce. Thus, we aimed to evaluate the effect of supplementation with different levels of CP on the expression of genes involved in the urea cycle and muscle and mammary gland development of Holstein × Gyr crossbreed heifers grazing intensively managed Brachiaria decumbens throughout the year. Thirty-eight heifers with average initial BW of 172.5 ± 11.15 kg (mean ± SE) and 8.2 ± 0.54 mo of age were randomly assigned to 1 of 4 treatments: 3 protein supplements (SUP) fed at 5g/kg of body weight, plus a control group (CON, non-supplemented animals). The supplement CP levels evaluated were: 12, 24, and 36%. The study was divided into 4 seasons: rainy, dry, rainy-dry transition (RDT), and dry-rainy transition (DRT). On the penultimate day of each season, ultrasound images of the carcass and mammary gland were taken. Five animals from each treatment were randomly chosen on the last day of each season, and liver and muscle tissue biopsies were performed. The target genes were the mammalian target of rapamycin (mTOR) and adenosine monophosphate-activated protein kinase (AMPK) in the muscle samples. Carbamoyl phosphate synthetase (CPS), ornithine transcarbamylase (OTC), argininosuccinate synthetase (ASS), arginosuccinate lyase (ASL), and arginase (ARG) were evaluated in the liver samples. Data were analyzed using PROC GLIMMIX of the SAS with repeated measures. We observed a greater rib eye area (cm2) and fat thickness (mm) in SUP animals than in non-supplemented animals. However, we did not observe differences among SUP levels for both variables. No effects of supplementation were detected on mammary gland development. Nevertheless, seasonal effects were observed, where the RDT and dry season had the most and least accumulated fat in the mammary gland. In muscle, we observed greater expression of AMPK in non-supplemented animals than SUP animals. On the other hand, no differences were observed in gene expression between SUP and non-supplemented animals and among SUP animals for mTOR. Season affected both AMPK and mTOR; heifers had a greater AMPK gene expression on rainy than RDT. For mTOR, we observed greater gene expression in RDT and DRT than in rainy. No differences were observed among RDT, dry, and DRT, and between dry and rainy seasons for mTOR. We observed greater CPS, ASL, and ARG gene expression in SUP animals than in non-supplemented animals. Among SUP animals, supplement CP linearly affected CPS. In conclusion, the supplementation strategy did not affect mammary gland development and mTOR expression in muscle tissue. However, we observed a seasonal effect on mammary gland development and AMPK and mTOR expression. The CP supplementation increased the rib eye area and fat thickness, directly affecting AMPK expression in the muscle. Moreover, the CP supplementation increased urea cycle enzyme expression, indicating greater urea production in the liver.

Association between Hashimoto's thyroiditis and melanoma: a retrospective matched cohort study.

An inflammatory microenvironment has been shown to increase risk for malignant melanoma, suggesting that melanoma may be related to a pro-inflammatory state. Though Hashimoto's thyroiditis is one of the most common autoimmune diseases, there are no investigations of its relationship with melanoma. We aim to determine if Hashimoto's increases risk of developing melanoma. A retrospective, validated cohort of patients with a diagnosis of Hashimoto's between 2005 and 2020 were identified using the Olmsted County database. Patients were age and sex matched to controls without a Hashimoto's diagnosis. The primary outcomes were development of melanoma and time to first melanoma diagnosis. 4805 patients were included in the study, with 1726 (36%) having a diagnosis of Hashimoto's. Hashimoto's patients had no significant difference in risk of melanoma (relative risk 0.96, 95% CI 0.78-1.17) or nonmelanoma skin cancer (relative risk 0.95, 95% CI 0.86-1.06) compared with matched controls. This suggests that the local proinflammatory environment present in Hashimoto's does not contribute significantly to melanoma risk. Larger studies may be needed to further characterize the relationship between these diseases.

Tobacco use in first-episode psychosis, a multinational EU-GEI study.

BACKGROUND: Tobacco is a highly prevalent substance of abuse in patients with psychosis. Previous studies have reported an association between tobacco use and schizophrenia. The aim of this study was to analyze the relationship between tobacco use and first-episode psychosis (FEP), age at onset of psychosis, and specific diagnosis of psychosis. METHODS: The sample consisted of 1105 FEP patients and 1355 controls from the European Network of National Schizophrenia Networks Studying Gene-Environment Interactions (EU-GEI) study. We assessed substance use with the Tobacco and Alcohol Questionnaire and performed a series of regression analyses using case-control status, age of onset of psychosis, and diagnosis as outcomes and tobacco use and frequency of tobacco use as predictors. Analyses were adjusted for sociodemographic characteristics, alcohol, and cannabis use. RESULTS: After controlling for cannabis use, FEP patients were 2.6 times more likely to use tobacco [p ⩽ 0.001; adjusted odds ratio (AOR) 2.6; 95% confidence interval (CI) [2.1-3.2]] and 1.7 times more likely to smoke 20 or more cigarettes a day (p = 0.003; AOR 1.7; 95% CI [1.2-2.4]) than controls. Tobacco use was associated with an earlier age at psychosis onset (ß = -2.3; p ⩽ 0.001; 95% CI [-3.7 to -0.9]) and was 1.3 times more frequent in FEP patients with a diagnosis of schizophrenia than in other diagnoses of psychosis (AOR 1.3; 95% CI [1.0-1.8]); however, these results were no longer significant after controlling for cannabis use. CONCLUSIONS: Tobacco and heavy-tobacco use are associated with increased odds of FEP. These findings further support the relevance of tobacco prevention in young populations.

Surgical and postsurgical management of abdominal paragangliomas and pheochromocytomas.

PURPOSE: To describe our current protocol for surgical and postsurgical management of abdominal paragangliomas (PGLs) and pheochromocytomas, with a special focus on multidisciplinary management in centres with experience. METHODS: The physicians involved in the management of patients with abdominal PGLs and pheochromocytomas of our hospital reviewed systematically current knowledge on the surgical management of abdominal PGLs and pheochromocytomas. RESULTS: Currently, surgery is considered the treatment of choice for abdominal PGLs and pheochromocytomas. The choice of surgical approach is determined based on the location of the lesion, size, patient́s body habitus and the likelihood of malignancy. Laparoscopic surgery is usually considered the gold standard approach for pheochromocytomas, but open access should be considered in invasive and/or potentially malignant tumours >8-10 cm and for abdominal PGLs. Postsurgical management of pheochromocytomas and PGLs includes close hemodynamic monitoring and treatment of postsurgical complications, the pathological study of the surgical specimen, reassessment of hormonal and/or radiological status and planning of follow-up based on the risk of recurrence and malignancy. CONCLUSION: Surgery represents the treatment of choice of most abdominal PGLs and pheochromocytomas. Optimal postsurgical evaluation, including hemodynamic, pathological, hormonal, and radiological evaluation, should be performed by a multidisciplinary team specializing in PGL/pheochromocytoma management.

Prevalence, risk factors and evolution of diabetes mellitus after treatment in primary aldosteronism. Results from the SPAIN-ALDO registry.

PURPOSE: To evaluate the prevalence, risk factors and evolution of diabetes mellitus (DM) after targeted treatment in patients with primary aldosteronism (PA). METHODS: A retrospective multicenter study of PA patients in follow-up at 27 Spanish tertiary hospitals (SPAIN-ALDO Register). RESULTS: Overall, 646 patients with PA were included. At diagnosis, 21.2% (n = 137) had DM and 67% of them had HbA1c levels < 7%. In multivariate analysis, family history of DM (OR 4.00 [1.68-9.53]), the coexistence of dyslipidemia (OR 3.57 [1.51-8.43]) and advanced age (OR 1.04 per year of increase [1.00-1.09]) were identified as independent predictive factors of DM. Diabetic patients were on beta blockers (46.7% (n = 64) vs. 27.5% (n = 140), P < 0.001) and diuretics (51.1% (n = 70) vs. 33.2% (n = 169), p < 0.001) more frequently than non-diabetics. After a median follow-up of 22 months [IQR 7.5-63.0], 6.9% of patients developed DM, with no difference between those undergoing adrenalectomy and those treated medically (HR 1.07 [0.49-2.36], p = 0.866). There was also no significant difference in the evolution of glycemic control between DM patients who underwent surgery and those medically treated (p > 0.05). CONCLUSION: DM affects about one quarter of patients with PA and the risk factors for its development are common to those of the general population. Medical and surgical treatment provides similar benefit in glycemic control in patients with PA and DM.

[Translated article] Current situation of robotics in knee prosthetic surgery: A technology that has come to stay?

Robotic surgery is a surgical technique that is on the rise. The goal of robotic-assisted total knee arthroplasty (RA-TKA) is to provide the surgeon with a tool to accurately execute bone cuts according to previous surgical planning to restore knee kinematics and balance of soft tissue, being able to precisely apply the type of alignment that we choose. In addition, RA-TKA is a very useful tool for training. Within the limitations, there is the learning curve, the need for specific equipment, the high cost of the devices, the increase in radiation in some systems and that each robot is linked to a specific type of implant. Current studies show, with RA-TKA, variations in the alignment of the mechanical axis are reduced, postoperative pain is improved and earlier discharge is facilitated. On the other hand, there are no differences in terms of range of motion, alignment, gap balance, complications, surgical time or functional results.

Una inusual causa de estrechez de la vía aérea laringotraqueal / An unusual cause of laryngotracheal airway narrowing

La enfermedad relacionada con inmunoglobulina (Ig) G4 es una enfermedad de reciente conocimiento que puede comprometer cualquier órgano teniendo preferencias por ciertas regiones del cuerpo, donde la región de cabeza y cuello es uno de sus principales puntos afectados, pudiendo comprometer tanto la órbita, glándulas salivales, glándulas lagrimales, glándula tiroides, cavidades paranasales, hueso temporal, faringe y laringe. Este último órgano es infrecuentemente comprometido, solo existiendo 12 casos registrados en la literatura antes de la publicación de este escrito. Presentamos un caso de una mujer de 49 años con historia de disnea frente a esfuerzo, diagnosticándose una estenosis subglótica la cual fue manejada quirúrgicamente con una reconstrucción laringotraqueal. En el estudio histopatológico se evidenció histología compatible con enfermedad relacionada con IgG4, por lo que se inició tratamiento médico con corticotera- pia oral por un lapso de 2 meses en conjunto con inmunología. Paciente luego de 4 años de seguimiento, no ha presentado recaídas, manteniendo un lumen subglótico adecuado.

Immunoglobulin (Ig) G4-related disease is a medical condition of recent knowledge that can compromise any organ, having preferences for certain regions of the body, where the head and neck region is one of the main affected points, being able to affect orbit, salivary glands, lacrimal glands, thyroid gland, paranasal cavities, temporal bone, pharynx and larynx. The latter is infrequently compromised, with only 12 cases registered in the literature before the publication of this writing. We present a case of a 49-year-old woman with a history of exertional dyspnea, diagnosed with a sub- glottic stenosis which was managed surgically with laryngotracheal reconstruction. The histopathological study revealed histology compatible with IgG4-related disease, so medical treatment with oral corticosteroid therapy was started for a period of 2 months in conjunction with immunology. After 4 years of follow-up, the patient has not presented relapses, maintaining an adequate subglottic lumen.

Use of internal-external diversion stent in open pyeloplasty in patients under one year of age. / Uso de catéter de derivación interno-externo en la pieloplastia abierta en menores de un año.

INTRODUCTION: There are various alternatives available for renal pelvis drainage following pyeloplasty. One of them is the use of an internal-external diversion stent, which according to our protocol, is knotted 48 hours following surgery, prior to discharge, and removed 7 days later on an outpatient consultation basis, with no sedation or analgesia required. OBJECTIVE: To analyze the results of patients under one year of age who underwent open pyeloplasty associated with an outpatient internal-external diversion stent. MATERIALS AND METHODS: A retrospective, descriptive analysis of 28 patients (31 renal units) undergoing surgery from 2011 to 2021 was carried out. Diagnostic methods, indications, surgical approach, and postoperative progression were assessed. RESULTS: 28 patients (23 male) prenatally diagnosed with hydronephrosis confirmed by ultrasonography and/or renogram underwent pyeloplasty at a median age of 3 months (15 days-11 months). Pyeloplasty was conducted according to the Anderson-Hynes technique or dismembered pyeloplasty in 28 renal units, and according to the Culp-DeWeerd technique or spiral flap in 3. In all cases, an internal-external diversion stent was used according to our protocol. Mean hospital stay was 3.5 days (2-7 days), with a good postoperative progression. 2 patients had complications (urinary infection requiring intravenous antibiotics, and pyonephrosis requiring re-pyeloplasty). CONCLUSIONS: Using an internal-external diversion stent following pyeloplasty in patients under 1 year of age with ureteropelvic junction obstruction is a simple and safe option that allows for early discharge with outpatient management. It also avoids a second general anesthesia for drainage catheter removal purposes.

INTRODUCCION: Existen diversas alternativas para el drenaje de la pelvis renal tras una pieloplastia. Una de ellas es la utilización de un catéter de derivación interno-externo que, según nuestro protocolo, se anuda a las 48 horas posoperatorias previas al alta y se retira a los siete días de forma ambulatoria en consulta, sin necesidad de sedoanalgesia. OBJETIVO: Analizar los resultados de los pacientes menores de un año intervenidos mediante pieloplastia abierta, asociando un catéter de derivación interno-externo de manejo ambulatorio. MATERIAL Y METODOS: Análisis descriptivo retrospectivo de 28 pacientes (31 unidades renales) intervenidos entre los años 2011 y 2021. Se evaluaron métodos diagnósticos, indicaciones, abordaje quirúrgico y evolución posoperatoria. RESULTADOS: Veintiocho pacientes (23 varones) con diagnóstico prenatal de hidronefrosis confirmado con ecografía y/o renograma, fueron intervenidos mediante pieloplastia a una mediana de edad de tres meses (15 días-11 meses). Se realizó pieloplastia según técnica de Anderson-Hynes o pieloplastia desmembrada en 28 unidades renales y según técnica de Culp-DeWeerd o colgajo en espiral en 3. En todos los casos se utilizó un catéter de derivación interno-externo según protocolo. El tiempo medio de ingreso fue 3,5 días (2-7 días) con buena evolución posoperatoria. Dos pacientes presentaron complicaciones (infección urinaria que requirió antibioterapia intravenosa y pionefrosis que requirió repieloplastia). CONCLUSIONES: Asociar un catéter de derivación interno-externo a la pieloplastia en pacientes menores de un año con estenosis de la unión pieloureteral es una opción sencilla y segura que permite un alta precoz con manejo ambulatorio y evita una segunda anestesia general para la retirada del catéter de drenaje.

Patient feedback receiving care using a shared decision making tool for thyroid nodule evaluation-an observational study.

PURPOSE: To characterize the feedback of patients with thyroid nodules receiving care using a shared decision making (SDM) tool designed to improve conversations with their clinicians related to diagnostic options (e.g. thyroid biopsy, ultrasound surveillance). METHODS: Investigators qualitatively analyzed post-encounter interviews with patients to characterize their feedback of a SDM tool used during their clinical visits. Additionally, investigators counted instances of diagnostic choice awareness and of patients' expression of a diagnostic management preference in recordings of clinical encounters of adult patients presenting for evaluation of thyroid nodules in which the SDM tool was used. RESULTS: In total, 53 patients (42 (79%) women); median age 62 years were enrolled and had consultations supported by the SDM tool. Patients were favorable about the design of the SDM tool and its ability to convey information about options and support patient-clinician interactions. Patients identified opportunities to improve the tool through adding more content and improve its use in practice through training of clinicians in its use. There was evidence of diagnostic choice awareness in 52 (98%) of these visits and patients expressed a diagnostic management preference in 40 (76%). CONCLUSION: User centered design including feedback from patients and real life observation supports the use of the SDM tool to facilitate collaboration between patients and clinicians.

Differences in intraoperative and surgical outcomes between normotensive pheochromocytomas and sympathetic paragangliomas (PPGLs) and hypertensive PPGLs: results from the PHEO-RISK STUDY.

PURPOSE: To compare the intraoperative and surgical outcomes of normotensive pheochromocytomas and sympathetic paragangliomas (PPGLs), hypertensive PPGLs and non-PPGL adrenal lesions. METHODS: This a retrospective multicenter cohort study of patients with PPGLs from 18 tertiary hospitals. A control group of histologically confirmed adrenocortical adenomas (non-PPGL group) was selected to compare intraoperative and surgical outcomes with of the normotensive PPGLs. RESULTS: Two hundred and ninety-six surgeries performed in 289 patients with PPGLs were included. Before surgery, 209 patients were classified as hypertensive PPGLs (70.6%) and 87 as normotensive PPGLs. A higher proportion of normotensive PPGLs than hypertensive PPGLs did not receive alpha presurgical blockade (P = 0.009). When we only considered those patients who received presurgical alpha blockers (200 hypertensive PPGLs and 76 normotensive PPGLs), hypertensive PPGLs had a threefold higher risk of intraoperative hypertensive crisis (OR 3.0 [95% 1.3-7.0]) and of hypotensive episodes (OR 2.9 [95% CI 1.2-6.7]) than normotensive PPGLs. When we compared normotensive PPGLs (n = 76) and non-PPGLs (n = 58), normotensive PPGLs had a fivefold higher risk of intraoperative complications (OR 5.3 [95% CI 1.9-14.9]) and a six times higher risk of postoperative complications (OR 6.1 [95% CI 1.7-21.6]) than non-PPGLs. CONCLUSION: Although the risk of intraoperative hypertensive and hypotensive episodes in normotensive PPGLs is significantly lower than in hypertensive PPGLs, normotensive PPGLs have a greater risk of intraoperative and postoperative complications than non-PPGL adrenal lesions. Therefore, it is recommended to follow the standard of care for presurgical and anesthetic management of PPGLs also in normotensive PPGLs.

Factores de riesgo, etapificación y pronóstico en carcinoma escamoso de cavidad oral

El carcinoma escamoso de cavidad oral corresponde a una de las neoplasias malignas más frecuentes en cabeza y cuello, teniendo una incidencia mundial según GLOBOCAN para el año 2020 de 377.713 casos nuevos. Este cáncer tiene la ventaja potencial de su diagnóstico precoz por su accesibilidad al examen físico, por lo que es importante tener un alto índice de sospecha en pacientes con los factores de riesgo como tabaquismo crónico, consumo de alcohol, consumo de nuez de betel, inmunodeficiencias, entre otros, teniendo una conducta activa con el fin de lograr un diagnóstico precoz. Por otro lado, la etapificación actual incorpora nuevos factores pronósticos, como la profundidad de invasión, con el fin de asignar de mejor forma una clasificación adecuada y con ello, guiar el tratamiento de estos pacientes. Finalmente, se debe procurar un diagnóstico y tratamiento precoz con el fin de lograr los mejores resultados oncológicos.

Squamous cell carcinoma of the oral cavity represents one of the most frequent malignant neoplasms in the head and neck, having an incidence according to GLOBOCAN for the year 2020 of 377,713 new cases. This cancer has the potential advantage of early diagnosis due to its accessibility to physical examination, so it is important to have a high index of suspicion in patients with risk factors such as chronic smoking, alcohol consumption, betel nut consumption, immunodeficiencies, among others, having an active behavior in order to achieve an early diagnosis. On the other hand, the current staging incorporates new prognostic factors, such as depth of invasion, in order to better assign an adequate classification and thus guide the treatment of these patients. Finally, early diagnosis and treatment should be sought in order to achieve the best oncological outcomes.
