Evaluación de la agudeza diagnóstica de la Ecografía Translaríngea Transcutánea (ETLTC) en la valoración de la movilidad de las cuerdas vocales en cirugía de tiroides y paratiroides / Evaluation of the diagnostic acuity of the Transcutaneous Translaryngeal Ultrasound (TCTLUS) in the assessment of the vocal cords mobility in thyroid and parathyroid surgery

Introducción. La evaluación de la movilidad de las cuerdas vocales en cirugía de tiroides y paratiroides hace parte de la adecuada valoración integral. Aunque la laringoscopia directa es prueba de referencia, su uso real no es rutinario por lo que se propone la ecografía translaríngea como alternativa de evaluación. Métodos. Estudio prospectivo de evaluación de una prueba diagnóstica de la movilidad de las cuerdas vocales pre y posoperatoria, comparando la ecografía translaríngea con la video laringoscopia, en pacientes con cirugía de tiroides y paratiroides, de febrero 1° a noviembre 30 de 2022. Se describieron las variables usando frecuencias absolutas y relativas. En el análisis univariado se calcularon Chi cuadrado y T de Student y en el bivariado, regresión logística binaria. La agudeza diagnóstica se determinó con sensibilidad, especificidad y valores predictivos; se consideró la significancia estadística con p < 0,05. Resultados. Se incluyeron 267 pacientes, 219 mujeres y 48 hombres; 196 pacientes (73,4%) tenían malignidad. Se encontró en el preoperatorio, sensibilidad 100 %, especificidad 99,6 %, VPP 83,3 %, VPN 100 %, odds de probabilidad positiva 83 % y Odds de probabilidad negativa 0,004 %. En el posoperatorio, sensibilidad 82,8 %, especificidad 99,2 %, VPP 92,3 % VPN 97,9 %, odds de probabilidad positiva 92 % y odds de probabilidad negativa 0,2 %. Conclusiones. La ecografía translaríngea en nuestro medio tiene alta agudeza diagnóstica. Podría ser usada en el abordaje inicial de la evaluación de la movilidad de las cuerdas vocales y reemplazar la laringoscopia directa, dejando ésta para cuando la visualización ecográfica no sea adecuada, o en casos de afectación o sospecha de invasión, para su confirmación.

Introduction. The evaluation of the mobility of the vocal cords in thyroid and parathyroid surgery is part of the adequate comprehensive assessment. Altough, direct laryngoscopy is the gold standard, its real use is not routine, so translaryngeal ultrasound approach is proposed as an alternative. Methods. A prospective diagnostic test study was carried out to evaluate the translaryngeal ultrasound compared with video laryngoscopy in visualizing vocal mobility in patients with thyroid and parathyroid surgery from February 1 to November 30, 2022. Patients were described using absolute and relative frequencies. Univariate statistical analysis with Chi-square and Student's t tests. T. Bivariate analysis using binary logistic regression. Diagnostic acuity was calculated with sensitivity, specificity, PPV, NPV. Statistical significance with p< 0.05, 95% confidence interval. Results. 267 patients undergoing thyroid or parathyroid surgery were included, 219 women and 48 men. Malignant: thyroid neoplasm 196 patients (73.4%). The findings were for the preoperative period, 100% sensitivity, 99.6% specificity, PPV 83.33%, NPV 100%, 83% positive probability odds, and 0.004% negative probability odds. For the postoperative period, 82.8% sensitivity, 99.2% specificity, 92.3% PPV, 97.9% NPV, 92% positive probability odds, and 0.2% negative probability odds were found.Conclusions. Translaryngeal ultrasound in our series has high diagnostic acuity. It could be used as the initial approach to evaluate vocal mobility and might replace direct laryngoscopy, leaving it when its visualization is not adequate or in cases of involvement or suspected invasion for confirmation.

Bocio endotorácico / Endothoracic Goiter

Introducción: Un bocio se considera intratorácico cuando más de un 50 por ciento de la glándula tiroides está en el mediastino, o sea, por debajo del nivel del estrecho torácico superior. Se trata de una enfermedad poco frecuente que padece aproximadamente el 3 por ciento de los pobladores del mundo. La incidencia del bocio nodular ha disminuido debido a la ingestión en algunos países de sal yodada y alimentos ricos en yodo. Esta enfermedad alcanza alrededor del 10 por ciento de las masas mediastínicas. Objetivo: Presentar el caso de un paciente masculino, operado de bocio endotorácico en la provincia de Cienfuegos. Presentación de caso: Se presenta un paciente masculino, de 48 años de edad, que acude a consulta y refiere aumento de volumen del cuello en la región anterior, que se acompaña de decaimiento y en ocasiones disfagia tanto a los alimentos líquidos como a los sólidos. Además, refiere ligera disnea que tolera adecuadamente cuando realiza las actividades de la vida diaria. Por tratarse de una enfermedad poco frecuente, se considera de interés científico publicar el caso para conocimiento de los profesionales dedicados al estudio y tratamiento de las afecciones tiroideas. Conclusiones: El bocio endotorácico es una entidad poco frecuente y en todos los casos requiere de intervención quirúrgica(AU)

Introduction: A goiter is considered intrathoracic when more than 50 percent of the thyroid gland is in the mediastinum; in other words, below the level of the superior thoracic outlet. It is a rare disease that affects approximately 3 percent of the world's population. The incidence of nodular goiter has decreased due to the ingestion of iodized salt and iodine-rich foods in some countries. This disease accounts for about 10 percent of mediastinal masses. Objective: To present the case of a male patient operated on for endothoracic goiter in the province of Cienfuegos. Case presentation: The case is presented of a 48-year-old male patient who comes for consultation referring a volume increase in the anterior neck region, accompanied by decay and sometimes dysphagia to both liquid and solid food. In addition, he reports slight dyspnea that he tolerates adequately when performing daily living activities. Since this is a rare disease, it is considered of scientific interest to publish the case for the knowledge of professionals dedicated to studying and treating thyroid disorders. Conclusions: Endothoracic goiter is a rare entity and, in all cases, requires surgical intervention(AU)

Lacrimal gland pleomorphic adenoma: a narrative review / Adenoma pleomórfico de glândula lacrimal: uma revisão narrativa

ABSTRACT We present a literature review of 57 publications describing this pathology, published from the year 2012. In all these studies patients were reported to depict a slow-growing, motionless mass, which is painless at most times. All cases were managed by total excision, except for one report where adjuvant radiotherapy was applied. Among the several therapeutic strategies, the total tumor resection, preserving the tumor pseudocapsule intact, appears to be a consensus in treating the disease efficiently. Furthermore, fine-needle aspiration biopsy, including the assessment of genetic alterations, has proved to be a valuable tool in the diagnosis of challenging cases. Our literature survey also suggests that an incisional biopsy before the surgery may lead to the pseudocapsule disruption, thus considerably increasing the chances of adenoma recurrence, enabling its malignization. At present, genetics studies indicate that the molecular aberrations involved in the adenoma are similar to those represented in the salivary gland tumor pathogenesis. Further, in the recurrent cases, the pathology becomes difficult to treat and multiple surgeries may be required, occasionally, leading to radical surgery treatment.

RESUMO Uma revisão narrativa da literatura de 57 publicações que descrevem esta patologia, publicada a partir de 2012. Os pacientes têm uma massa de crescimento lento e imóvel, que na maioria das vezes é indolor. Todos os casos foram tratados por excisão total, com exceção de um relatório de radioterapia adjuvante. Entre as estratégias terapêuticas encontradas, a ressecção total do tumor, preservando a pseudocápsula tumoral intacta, parece ser um consenso. Alternativamente, a biópsia por aspiração de agulha fina incluindo a avaliação de alterações genéticas pode representar uma ferramenta valiosa nos casos diagnósticos desafiadores. Uma biópsia incisional antes da cirurgia não é recomendada, pois a ruptura da pseudocápsula aumenta consideravelmente a recorrência do adenoma, permitindo até mesmo sua malignização. Com relação à genética, estudos atuais indicam que as aberrações moleculares envolvidas no adenoma são semelhantes às da patogênese do tumor da glândula salivar. Para casos de recorrência, a patologia torna-se difícil de tratar e múltiplas cirurgias podem ser necessárias, às vezes levando a um tratamento cirúrgico radical.

Primary basal cell carcinoma of the caruncle: case report and review of the literature

ABSTRACT We present a rare case of primary caruncle basal cell carcinoma (BCC), a condition with limited occurrences. Our patient, an 80-year-old woman without prior ocular pathological history, presented a 2x2mm pedunculated blackish nodular lesion on the caruncle of her left eye, without local conjunctival or cutaneous involvement. Histological analysis following complete excision confirmed the presence of basal cell carcinoma within the caruncle. Over a span of 30 months, no recurrence has been observed. While scant cases are documented in the literature, we conducted a review of these instances. Despite its infrequent manifestation, this condition should be taken into account when evaluating caruncular tumors, given its tendency to invade the orbit. Complete excision with free surgical margins is the treatment of choice, and adjuvant radiotherapy or chemotherapy might be considered.

EZH2 immunoexpression in pleomorphic adenoma and adenoid cystic carcinoma and clinicopathological features

Abstract The aim of this study was to evaluate the expression of the EZH2 protein and describe the clinical and microscopic characteristics of adenoid cystic carcinoma (ACC) and pleomorphic adenoma (PA). The study included 16 ACC cases and 12 PA. All ACC and PA cases were positive for EZH2 and the ACC samples showed significantly higher EZH2 expression. The clinical and microscopic covariates were described in relation to EZH2 staining in ACC samples. The highest mean values of EZH2 were observed in cases with local metastasis, recurrence, perineural invasion, and predominantly cribriform growth pattern without solid areas. EZH2 is a potential marker of malignancy.

Unilateral parotid gland Simultaneously primary two different pathological tumors: a case report and literature review / 口腔疾病防治

Objective@#To explore the clinical manifestations, histopathological characteristics, diagnosis, treatment, and prognosis of simultaneous unilateral primary tumors of different pathological types in the parotid gland.@*Methods@#A case of simultaneous unilateral primary parotid gland tumors, i.e., adenolymphoma and basal cell adenoma, was reviewed and analyzed in combination with the literature.@*Results@#The patient discovered a lump in the right parotid gland area one month prior to presentation, and a tumor was palpated in the shallow lobe of the right parotid gland before surgery. According to MR images, the initial diagnoses were tumors of the shallow and deep lobes of the right parotid gland. The tumors of the deep and shallow lobes were excised with part of the gland, and the facial nerves were dissected under general anesthesia. Postoperative pathology revealed an adenolymphoma in the shallow lobe of the right parotid gland and a basal cell adenoma with cystic transformation in the deep lobe. The surgical effect was good, with no complications, and there was no recurrence after 1 year of follow-up. A review of the relevant literature showed that multiple primary tumors of the parotid gland can manifest as the simultaneous presence of two or more types of tumors on both sides or on one side, and the disease is mainly treated with surgery.@*Conclusion@#Multiple unilateral primary parotid gland tumors are rare. Imaging examinations need to be combined with clinical evaluations to prevent missed diagnoses. Surgery is the first treatment option, and patients with benign tumors have a good prognosis.

Changes of binocular surface indexes after unilateral endoscopic dacryocystorhinostomy / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To investigate the effect of unilateral endoscopic dacryocystorhinostomy on binocular surface indexes.METHODS: Totally 45 cases with monocular primary acquired nasolacrimal duct obstruction(PANDO)who successfully underwent endoscopic dacryocystorhinostomy between 1 December 2022 and 31 July 2023 were enrolled in the study. Ocular surface indexes, including the non-invasive tear break-up time(NIBUT), Sj&#x0026;#xF6;gren's International Collaborative Clinical Alliance ocular staining score(SICCA OSS), Korb score of lid wiper and Schirmer test scores, were collected preoperatively and at 0.5, 1 and 3 mo post-operatively. Subsequently, various indexes were compared at each time point between the operated and healthy eyes pre- and post-operatively.RESULTS: There was no significant differences between operated and healthy eyes in NIBUT, SICCA OSS, Korb scores and Schirmer test(all P&#x003E;0.05). Furthermore, the Korb scores of operated eye at 0.5, 1 and 3 mo post-operatively were significantly lower than the preoperative value(P=0.034, 0.044, 0.027). Moreover, the Schirmer test score of the operated eye at 1 mo post-operatively was significantly lower than the preoperative value(P=0.0461).CONCLUSION:After a successful endoscopic dacryocystorhinostomy, tear drainage is restored, however, ocular surface damage worsens. These changes typically peak at 1 mo post-operatively before gradually improving.

Correlation between ocular surface status and blood lipids in patients with meibomian gland dysfunction during pregnancy / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To analyze the correlation between ocular surface status and serum lipids in patients with meibomian gland dysfunction(MGD)during pregnancy, and to provide new ideas for the management and treatment of MGD during pregnancy.METHODS: Totally 120 pregnant women(240 eyes)treated in our hospital from May 2021 to May 2022 were selected and they were divided into MGD group(60 cases, 120 eyes)and control group(60 cases, 120 eyes)according to the presence or absence of MGD. All subjects received the ocular surface disease index scores(OSDI)and underwent examinations of meibomian gland morphology and function, tear film and blood lipid.RESULTS: The scores of OSDI, the related indexes of meibomian gland, corneal fluorescein staining(FL)scores, total cholesterol(TC), triglyceride(TG)and low density lipoprotein-cholesterol(LDL-C)in the MGD group were significantly higher than those in the control group(P&#x0026;#x003C;0.05). The scores of fluorescein breakup time(FBUT), Schirmer Ⅰ test(SIt)and high-density lipoprotein cholesterol(HDL-C)in the MGD group were significantly lower than those in the control group(P&#x0026;#x003C;0.05). Correlation analysis showed that the scores of TG, TC, LDL-C were negatively correlated with the values of FBUT(rs =-0.702, -0.647, -0.710, all P&#x0026;#x003C;0.001).CONCLUSION: The level of blood lipids in pregnant patients with MGD is significantly increased, and the levels of TC, TG and LDL-C may be related to the stability of tear film.

Evaluation of asymptomatic ocular surface disorders in hospitalized patients with primary pterygium before surgery / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To investigate the preoperative ocular symptoms and the characteristics of asymptomatic ocular surface abnormalities in hospitalized patients with primary pterygium.METHODS: Cross-sectional study. Hospitalized patients diagnosed with primary pterygium and scheduled to receive pterygium excision surgery at the Xiamen Eye Center of Xiamen University from August 2022 to October 2022 were enrolled. Ocular surface disease index questionnaire(OSDI), six examinations including non-invasive tear film break-up time, Schirmer I test, tear meniscus height, lid margin abnormality, meibomian gland dropout and tear film lipid layer thickness, and anterior segment optical coherence tomography(AS-OCT)were performed and statistically analyzed.RESULTS: A total of 178 cases(178 eyes), with a mean age of 54.39±10.75 years old, were recruited, including 75 males(42.1%)and 103 females(57.9%). The average values of ocular surface parameters in these patients included OSDI: 11.47±9.69, tear film break-up time: 7.10±3.86 s; tear meniscus height: 0.16±0.07 mm, Schirmer I test values: 14.39±7.29 mm/5 min, and pterygium thickness: 504.74±175.87 μm. Totally 161 eyes(90.4%)presented with abnormal lid margin, 44 eyes(24.7%)presented with meibomian gland dropout score ≥4, 52 eyes(29.2%)presented with low lipid layer thickness. In the 6 objective examinations, abnormalities in at least 4 of these tests were found in 85.4% of eyes. Pterygium morphology was classified into four grades: 10 eyes(5.6%)of grade Ⅰ, 93 eyes(52.2%)of grade Ⅱ, 60 eyes(33.7%)of grade Ⅲ, and 15 eyes(8.4%)of grade Ⅳ. In patients with a higher grade of pterygium, the tear film break-up time was lower, and the proportion of abnormal lid margin was also significantly higher(P&#x0026;#x003C;0.05). The patients were further divided into two subgroups, including 121 eyes(68.0%)with normal OSDI &#x0026;#x003C;13 in the normal group and 57 eyes(32.0%)with OSDI ≥13 in the abnormal group. No significant difference was found in the proportion of meibomian gland dysfunction between the two groups of patients(71.9% vs. 71.9%, P=0.872). In addition, there were differences in the number of abnormal objective examinations(4.11±0.85 vs. 4.91±0.99, P&#x0026;#x003C;0.001).CONCLUSIONS: Asymptomatic ocular surface abnormalities were present preoperatively in patients hospitalized for primary pterygium. A comparable high incidence of structural or functional meibomian gland dysfunction existed in pterygium patients with or without apparent ocular discomfort. More attention should be paid to the ocular surface abnormalities in those asymptomatic patients before primary pterygium surgery.

Aspectos Morfológicos de la Mama. Una Revisión de la Literatura / Morphological Aspects of the Breast. A Literature Review

La glándula mamaria tiene su origen embriológico, posteriormente se diferencia histológica y anatómicamente; a lo largo del tiempo se han ido descubriendo nuevos hallazgos, además de nueva terminología. El objetivo de este trabajo consistió en describir la actualización en los aspectos morfológicos de la glándula mamaria. Se realizó una búsqueda de artículos en diferentes fuentes primarias y secundarias de la literatura científica como: Pubmed, Embase, WOS, Scopus, Scielo obteniendo 623 publicaciones, seleccionado 53 para su revisión y 17 incluidos. La mama se ha ido actualizando en los aspectos morfológicos; Los conductos se ubican cercanos a la areola y al pezón donde desembocan directamente, las ramificaciones de los conductos se ubican cercanos a la areola; los pezones tienen entre 15 y 20 lóbulos, de los cuales sólo 5-9 son verdaderos orificios del conducto mamario, no existen senos lactíferos por lo que la leche desemboca directamente en el pezón, en cuanto a la inervación de la mama son inervados por las ramas cutáneas anterior y lateral de los nervios intercostales. La evidencia existente demuestra la necesidad de realizar estudios permanentes en el ámbito de la morfología, como fue descrito en este artículo de revisión sobre la mama. En diferentes aspectos, tales como términos, funciones y estructuras. Está información es importante para, la formación de pregrado, post grado, y su utilización en la clínica, identificación de patologías, clínicas de lactancia, entre otros.

SUMMARY: The mammary gland has its embryological origin, later it differentiates histologically and anatomically; over time new findings have been discovered, as well as new terminology. The aim of this work was to describe the update on the morphological aspects of the mammary gland. A search for articles was carried out in different primary and secondary sources of scientific literature such as: Pubmed, Embase, WOS, Scopus, Scielo, obtaining 623 publications, 53 selected for review and 17 included. The breast has been updated in morphological aspects; the ducts are located close to the areola and the nipple where they open directly, the branches of the ducts are located close to the areola; the nipples have between 15 and 20 lobes, of which only 5- 9 are true mammary duct orifices, there are no lactiferous sinuses, so the milk flows directly into the nipple, in terms of innervation of the breast they are innervated by the anterior and lateral cutaneous branches of the intercostal nerves. The existing evidence demonstrates the need for permanent studies in the field of morphology, as described in this review article on the breast. In different aspects, such as terms, functions and structures. This information is important for undergraduate and postgraduate training, and its use in the clinic, identification of pathologies, lactation clinics, among others.

Sialendoscopy for treatment of major salivary glands diseases: a comprehensive analysis of published systematic reviews and meta-analyses

Abstract Objectives: Sialendoscopy is a minimally invasive procedure used to diagnose and treat obstructive salivary gland diseases. Previous studies in the topic have shown mixed results. The present study aimed to evaluate the efficacy and safety of sialendoscopy through previous systematic reviews for different outcomes of several diseases. We also aimed to assess studies' methodological quality and heterogeneity. Methods: We conducted a comprehensive systematic literature search of Pubmed, Embase, Lilacs and Cochrane Library. We included systematic reviews and meta-analyses that used sialendoscopy to treat both lithiasic and alithiasic salivary glands diseases. Data extraction included studies' characteristics and results. We assessed studies' methodological quality using the AMSTAR-2 (A Measurement Tool to Assess systematic Reviews 2) tool. Results: 13 studies were included in the review, being 9 in adult populations and 4 in pediatric populations. Sialendoscopy proved to be effective at the treatment of different lithiasic and other obstructive diseases, but with important heterogeneity. The technique was also considered highly safe in most studies. However, studies had a critically low quality of evidence. Conclusions: Most studies demonstrated high efficacy and safety of sialendoscopy, but with critically low quality of evidence. We still lack randomized studies in this field, and future systematic reviews on the topic should follow current guidelines to improve conduction and reporting.

Characterization of Salivary Gland Pain: A Review of the Literature / Caracterización del Dolor de Glándulas Salivales: Revisión de la Literatura

SUMMARY: The salivary glands in pathological conditions produce countless different clinical presentations, and due to their complex neuroanatomy, their pain symptoms vary widely. However, in the literature to date, few studies characterize salivary gland pain. The aim of this study was to conduct a literature review concerning the clinical characteristics of pain in various salivary gland pathologies. A literature review was done through a systematic search of scientific articles in the Web of Science (WoS), MEDLINE, Scopus, and Elton B. Stephens Company (EBSCO) databases. The free terms "salivary gland", "parotid gland", "submaxillary gland", "sublingual gland", and "pain" were used along with the Boolean operators OR and AND. The search yielded a total of 1896 articles, of which 60 fulfilled the inclusion criteria and were ultimately included in this review. It is described that pain is a nonspecific symptom of a glandular pathology and is characterized mainly by the location of the pain, which is correlated with the anatomical location of the affected salivary gland. Among the painful salivary gland pathologies, we found inflammatory disorders, including infections, obstructions, disorders secondary to hyposalivation; systemic autoimmune diseases; neoplasms, and neuropathic pain disorders. The diagnosis and management of salivary gland pain require knowledge of the causes and mechanisms of the pain, and it is to recognize the signs and symptoms of salivary gland disorders to be able to diagnose and treat them.

Las glándulas salivales en condiciones patológicas producen un sinfín de presentaciones clínicas diferentes, y debido a su compleja neuroanatomía generan variaciones en su sintomatología dolorosa. Sin embargo, en la literatura hasta ahora son escasos los estudios que caracterizan el dolor de glándulas salivales. El objetivo de este estudio fue realizar una revisión de la literatura respecto a las características clínicas del dolor en diversas patologías de glándulas salivales. Se realizó una revisión de la literatura, a través de la búsqueda sistemática de artículos científicos en las bases de datos Web of Science (WoS), MEDLINE, Scopus y Elton B. Stephens Company (EBSCO). A través de los términos libres: "salivary gland", "parotid gland", "submaxillary gland", "sublingual gland", "pain", junto con los operadores booleanos OR y AND. La búsqueda arrojó un total de 1896 artículos, de los cuales 60 cumplieron los criterios de inclusión y fueron finalmente incluidos en esta revisión. Se describe que el dolor es un síntoma poco específico para la patología glandular y está caracterizado principalmente por la localización del dolor, el cual se correlaciona con la ubicación anatómica de la glándula salival afectada. Dentro de las patologías dolorosas de glándulas salivales encontramos los trastornos inflamatorios, incluidas infecciones, obstrucciones, trastornos secundarios a hiposalivación; enfermedades sistémicas autoinmunes; neoplasias y trastornos de dolor neuropático. El diagnóstico y manejo del dolor de glándulas salivales requiere del conocimiento de las causas y mecanismos del dolor, siendo necesario reconocer los signos y síntomas de los trastornos de glándulas salivales para ser capaces de diagnosticarlos y tratarlos.

Endoscopic Orientation of Juxta-pituitary Carotid in Transsphenoidal Approaches: Critical Considerations for Clinical Applications

Abstract Introduction In sphenoid sinuses with ill-defined carotid bony landmarks, accidental injury of the internal carotid artery (ICA) remains one of the most challenging complications, which is particularly reported in the endoscopic endonasal transsphenoidal approaches (EETAs). Objectives To describe an anatomical model for the endoscopic orientation of the juxta-pituitary segment of the ICA in relation to the lateral opticocarotid recess (OCR) as a nearby bony landmark. Methods Dissection was performed progressively, simulating the EETA, in twenty fresh adult cadavers. After reducing the posterior and lateral walls of the sphenoid sinuses, various measurements were taken from both lateral OCRs to "contact points" on the juxta-pituitary segment of the ICA and lateral margins of the pituitary gland. Results The current results have enabled us to divide the region between the lateral OCRs into 3 compartments: 2 lateral parasellar compartments contain juxta-pituitary segments of the ICA with a mean width of 8 mm and a narrow range from 7 mm to 10 mm; and a central intercarotid sellar compartment represents the safe region for bone drilling, showing widely variable widths ranging from 9 mm to 20 mm. In all specimens, the variation in the width of the intercarotid compartment correlated with the distance between both lateral OCRs. Conclusion The present study improves surgeon awareness of the variations in the course of the ICA through the EETA along sphenoid sinuses with ill-defined bony landmarks. An appreciation of the measurements taken in the present study can help in operative training, and can also provide a base for future studies to confirm ICA courses associated with a higher risk of injury.

Puede ser curativo o paliativo y se desarrolla de manera efectiva en la medicina moderna. Este tratamiento busca mitigar la quinta causa de muerte a nivel mundial, el cáncer de mama. La presente investigación es una revisión bibliográfica acerca de la crioablación percutánea como un método seguro que no involucra a otros órganos cercanos a la parte a intervenir. Es un procedimiento ambulatorio, con imagen guiada, mínima invasión, anestesia local y recuperación inmediata. Los resultados demuestran que es recomendable en pacientes de edad avanzada o que por su enfermedad tengan alto riesgo en cirugías y para cualquier paciente con el padecimiento referido. El objetivo del estudio es fundamentar teóricamente los beneficios de la crioterapia, medir y probar su eficacia, así como su tolerancia a largo y mediano plazo.

Cryoablation is a cryotherapy treatment for tumors located in the lungs, mediastinum, bones, liver, kidney, prostate, and breast. It can be curative or palliative and is effectively developed in modern medicine. It seeks to mitigate the fifth cause of death worldwide, breast cancer. The present investigation is a bibliographic review about percutaneous cryoablation as a safe method that does not involve other organs close to the part to be intervened. It is an outpatient procedure, with guided image, minimal invasion, local anesthesia and immediate recovery. The results show that it is recommended in elderly patients or those who are at high risk for surgery due to their disease and for any patient with the aforementioned condition. The objective of the study is to theoretically support the benefits of cryotherapy, measure and test its efficacy, as well as its tolerance in the long and medium term.

Escisión de Glándula Submandibular por Sialoadenitis Crónica Esclerosante Asociada a Sialolito en el Conducto Submandibular / Submandibular Gland Excision Due to Chronic Sclerosing Sialadenitis Associated With Sialolith in Submandibular Duct

La sialoadenitis crónica esclerosante puede extenderse desde una sialoadenitis focal hasta una cirrosis completa de la glándula. Aparece entre los 40 y 70 años de edad y afecta principalmente a la glándula submandibular. Se asocia con sialolitos y agentes infecciosos inespecíficos. La causa más frecuente de sialolitiasis es la formación de cálculos macroscópicamente visibles en una glándula salival o en su conducto excretor, de los cuales el 80 % al 90 % provienen de la glándula submandibular. Esta predilección probablemente se deba a que su conducto excretor es más largo, más ancho y tiene un ángulo casi vertical contra la gravedad, contribuyendo así a la estasis salival. Además, la secreción semimucosa de la misma es más viscosa. El sitio principal de ubicación de los litos en el conducto submandibular es la región hiliar con un 57 %. La sintomatología típica de la sialolitiasis es el cólico con tumefacción de la glándula y los dolores posprandiales. Reportamos el caso de un paciente masculino de 55 años, quien ingresa al servicio de Cirugía Oral y Maxilofacial del Hospital General Balbuena de la Ciudad de México por presentar un aumento de volumen en la región submandibular izquierda de consistencia dura y dolorosa a la palpación de 15 días de evolución, acompañada de aumento de temperatura en la zona compatible con un absceso. Los estudios de imagen reportan un sialolito en la región hiliar del conducto submandibular de 2,0 x 1,7 x 1,0 cm. Debido a su localización y tamaño, el tratamiento ideal en estos casos es la escisión de la glándula junto con el lito previo drenaje del absceso e inicio de terapia antibiótica doble.

Chronic sclerosing sialadenitis can range from focal sialadenitis to complete cirrhosis of the gland. It appears between 40 and 70 years of age and mainly affects the submandibular gland. It is associated with sialoliths and nonspecific infectious agents. The most common cause of sialolithiasis is the formation of macroscopically visible stones in a salivary gland or its excretory duct, of which 80 % to 90 % come from the submandibular gland. This predilection isprobably due to the fact that their excretory duct is longer, wider and has an almost vertical angle against gravity, thus contributing to salivary stasis. In addition, the semimucous secretion of it is more viscous. The main location of the stones in the submandibular duct is the hilar region with 57 %. The typical symptomatology of sialolithiasis is colic with swelling of the gland and postprandial pain. We report the case of a 55-year-old male patient, who was admitted to the Oral and Maxillofacial Surgery Service of the Hospital General Balbuena in Mexico City due to an increase in volumen in the left submandibular region that was hard and painful on palpation of 15 days of evolution, accompanied by increased temperature in the area compatible with an abscess. Imaging studies report a 2.0 x 1.7 x 1.0 cm sialolith in the submandibular duct hilar region. Due to its location and size, the ideal treatment in these cases is excision of the gland together with the stone previous drainage of the abscess and initiation of dual antibiotic therapy.

Evaluación de guías prácticas y preservación de la glándula submandibular en la disección del cuello

Introducción: Las guías prácticas de atención al cáncer de cabeza y cuello abordan actualmente la preservación funcional de algunos órganos dentro del tratamiento oncoespecífico. Objetivos: Evaluar guías de práctica clínica y cómo abordan la preservación de la glándula submandibular en la disección del cuello. Métodos: Se realizó una investigación cuantitativa, descriptiva y transversal, donde se evaluaron seis guías de atención al cáncer de cabeza y cuello, en cuanto a su calidad metodológica y la preservación de la glándula submandibular en la disección del cuello. Se utilizó el instrumento Appraisal of Guidelines Research and Evaluation y se conformó un equipo compuesto por cuatro evaluadores que dieron su consentimiento y fueron capacitados en su uso. Para el análisis de la información se empleó el Statistical Package for Social Sciences versión 21 y se calculó la puntuación de calidad para cada dominio y el coeficiente de correlación intraclase. Resultados: La mayor puntuación de calidad correspondió a los dominios 1, 4 y 6. La guía con mayor puntuación de calidad fue la de la Sociedad Europea de Oncología Médica, con una media de 94,3 por ciento, mientras que la de la Sociedad China de Oncología Clínica obtuvo el menor valor para un 71,5 por ciento. Tres guías obtuvieron la máxima puntuación de calidad (7) en la evaluación global. La mayor fuerza de concordancia entre los evaluadores correspondió a la guía de la Sociedad Americana de Oncología Clínica (1) y la menor a la del Instituto Nacional de Oncología y Radiobiología (0,93). Conclusiones: Las guías de práctica clínica del cáncer de cabeza y cuello evaluadas presentaron una alta calidad metodológica y la preservación de la glándula submandibular en la disección del cuello no fue abordada en ninguna(AU)

Introduction: Practical guidelines for head and neck cancer care currently address the functional preservation of some organs within oncospecific treatment. Objectives: To evaluate clinical practice guidelines and how they address the preservation of the submandibular gland in neck dissection. Methods: A quantitative, descriptive and cross-sectional research was carried out to evaluate six guidelines for head and neck cancer care, in terms of their methodological quality and the preservation of the submandibular gland in neck dissection. The Appraisal of Guidelines Research and Evaluation instrument was used, a team was composed by four evaluators who gave their consent and were trained to use such instrument. For the analysis of the information, the Statistical Package for Social Sciences version 21 was used and the quality score for each domain and the intraclass correlation coefficient were calculated. Results: The highest quality score corresponded to domains 1, 4 and 6. The guide with the highest quality score was that of the European Society of Medical Oncology reporting an average of 94.3 percent, while that of the Chinese Society of Clinical Oncology obtained the lowest value (71.5 percent). Three guidelines had the highest quality score (7) in the global evaluation. The highest strength of agreement between the evaluators corresponded to the guideline of the American Society of Clinical Oncology (1) and the lowest to that of the National Institute of Oncology and Radiobiology (0.93). Conclusions: The head and neck cancer clinical practice guidelines evaluated presented high methodological quality and the preservation of the submandibular gland in neck dissection was not addressed in any of them(AU)

Isolated tubercular dacryoadenitis in a non-immunocompromised healthy adult

A middle-aged woman presented with a slowly enlarging mass in the right superotemporal orbit and ptosis. The patient had an elevated erythrocyte sedimentation rate, and incisional biopsy showed granulomatous inflammation with Langhan's giant cells suggestive of a tubercular etiology. Tuberculin skin test was negative. The patient responded well to anti-tuberculous therapy. Tubercular dacryoadenitis is a rare presentation of a lacrimal gland mass.

Oncocytic sialolipoma of parotid gland: Case report and literature review

Neoplastic lipomatous lesions of the salivary glands constitute ?0.5% of all the salivary gland tumors. Oncocytic sialolipoma of the parotid glands is extremely uncommon. We report a case of oncocytic sialolipoma of the parotid gland in a 59-year-old male who presented with a gradually increasing swelling of the right parotid. Excisional parotid biopsy performed in view of possible pleomorphic adenoma as suggested on ultrasonography showed histological features consistent with oncocytic sialolipoma. We also described the characteristics of 24 previously reported cases of oncocytic sialolipoma of the parotid gland. The median age of the patients including the present case was 56 years (range 7–89), and 14 were male. The largest and the least reported sizes of the tumor were 7.0 and 1.4 cm, respectively. The left-sided parotid gland was more commonly involved (14/23). Despite its rarity, oncocytic sialolipoma should be considered in lipomatous parotid lesions showing epithelial components with oncocytic changes.

Complicações pós-operatórias relacionadas a ressecção do ameloblastoma / Postoperative complications related to ameloblastoma / Complicaciones postoperatorias relacionadas con la resección de ameloblastoma

A ressecção é o tratamento de escolha para tratamento do ameloblastoma, este que é o tumor odontogênico mais comuns, excluindo os odontomas. A desregulação de diversos genes no desenvolvimento de dentes pode desempenhar papel em sua histogênese. Alguns eventos adversos podem ocorrer durante seu tratamento pós-operatório. Recidivas ocorrem porque o ameloblastoma tende a se infiltrar entre o trabeculado ósseo esponjoso intacto na periferia do tumor antes que a reabsorção óssea se torne radiograficamente evidente. Consequentemente, a margem real do tumor sempre se estende além da sua imagem radiográfica ou da margem clínica. Deiscência de sutura é uma complicação que pode ocorrer no pós-operatório imediato na qual as bordas da ferida, que estão unidas por uma sutura, acabam se abrindo, aumentando o risco de infecção e dificultando assim a cicatrização. Fratura de placa de reconstrução é um evento possível de ocorrer em tratamentos de grandes defeitos. O estresse causado pela modelagem da placa durante a conformação da placa, além da ação muscular são uns dos fatores que pode fragilizar o metal da placa. Outras complicações podem ocorrer como: assimetrias, parestesia temporária e permanente do nervo alveolar inferior e deficiência estética e funcional. As descrições destes eventos na literatura ajudam aos clínicos conhecer e tentá-lo preveni-lo e com saber tratar... (AU)

Resection is the treatment of choice for treating ameloblastoma, which is the most common odontogenic tumor, excluding odontomas. The dysregulation of several genes in the development of teeth may play a role in their histogenesis. Some adverse events may occur during your postoperative treatment. Relapses occur because ameloblastoma tends to infiltrate between intact cancellous bone trabeculae at the pe riphery of the tumor before bone resorption becomes radiographi cally evident. Consequently, the actual tumor margin always extends beyond its radiographic image or clinical margin. Suture dehiscence is a complication that can occur in the immediate postoperative period in which the edges of the wound, which are joined by a suture, end up opening, increasing the risk of infection and thus hindering healing. Reconstruction plate fracture is a possible event to occur in large de fect treatments. The stress caused by the modeling of the plate during the formation of the plate, in addition to muscle action, are one of the factors that can weaken the plate metal. Other complications may occur, such as: asymmetries, temporary and permanent paresthesia of the inferior alveolar nerve and aesthetic and functional deficiency.

Caracterización del paciente geriátrico portador de nódulos de tiroides

Fundamento: las enfermedades de la glándula tiroidea son comunes en los adultos mayores y, muchas veces, cursan inadvertidas. Objetivo: caracterizar clínica y ultrasonográficamente a los pacientes geriátricos portadores de nódulo de tiroides. Métodos: se realizó un estudio observacional descriptivo de corte transversal, en el Servicio de Geriatría del Hospital General Docente Martín Chang Puga de la provincia de Camagüey, durante los años 2019 al 2022. Se incluyeron los 48 gerontes atendidos en el servicio y diagnosticados con enfermedad nodular del tiroides. Los datos se obtuvieron de las historias clínicas de los pacientes. Se analizaron las variables edad (por grupos de edades), sexo, color de la piel, manifestaciones clínicas y diagnóstico ecográfico. Resultados: el grupo etario de mayor afectación estuvo entre 60 a 69 años con predominio del femenino y del color blanco de la piel. La astenia prevaleció dentro de las manifestaciones clínicas. En el diagnóstico ecográfico prevaleció el nivel I, según el Thyroid Imaging Reporting and Data System. Conclusiones: la alta prevalencia de las enfermedades del tiroides, en especial en el adulto mayor, hace necesario la realización de un cribado para el diagnóstico ecográfico, al ser una prueba diagnóstica beneficiosa, fiable y a un bajo costo en Atención Primaria de Salud.

Foundation: thyroid gland diseases are common in older adults and often go unnoticed. Objective: to characterize clinically and ultrasonographically geriatric patients with thyroid nodule. Methods: a cross-sectional descriptive observational study was carried out in the Martín Chang Puga Teaching General Hospital geriatrics service in Camagüey province, from 2019 to 2022. 48 elderly were the universe made up who attended in the service, and were diagnosed with nodular thyroid disease. The data was obtained from the patients' medical records, the age groups; sex, skin color, clinical manifestations, and ultrasound diagnosis were the analyzed variables. Results: the most affected age group was between 60 and 69 years old, with a predominance of females and white skin color. Asthenia prevailed within the clinical manifestations. In the ultrasound diagnosis, level I prevailed, according to the Thyroid Imaging Reporting and Data System. Conclusions: the high prevalence of thyroid diseases, especially in the elderly, makes it necessary to perform a screening for ultrasound diagnosis, as it is a beneficial, reliable and low-cost diagnostic test in Primary Health Care.
