Tratamiento de diente evaginado mediante técnica de apexificación: reporte de caso / Treatment of dens evaginatus by apexification technique: a case report

El diente evaginado (DE) es una anomalía del desa-rrollo que se define como un tubérculo o protube-rancia que se extiende desde la superficie oclusal del diente afectado. La fractura o desgaste de esta pro-longación, internamente compuesta por tejido pul-par, puede causar diversas enfermedades pulpares, como pulpitis, necrosis pulpar e incluso dar lugar a una periodontitis apical. En el presente caso clíni-co se muestra el tratamiento de DE en un segundo premolar superior izquierdo que presentaba como diagnóstico necrosis pulpar y absceso alveolar cró-nico. El tratamiento consistió en realizar la terapia endodóntica con técnica de apexificación empleando BiodentineTM (AU)

Dens evaginatus (DE) is a dental developmental defect defined as a tubercle or protuberance that extends from the occlusal surface of the affected tooth. Fracture or wear of this extension, internally composed of pulp tissue, can cause diverse pulp diseases, such as pulpitis, pulpal necrosis and it can even induce apical periodontitis.The following clinical case shows the treatment of DE in a maxillary left second premolar diagnosed with pulp necrosis and chronic alveolar abscess. The treatment of choice was endodontic therapy using BiodentineTM (AU)

The diagnostic value of tuberculin skin test, tubercle bacillus-antibody, interferon-γ release assay, tubercle bacillus-DNA and bacterial collection centrifugal smear method in pneumoconiosis combined with tuberculosis / 中国医师进修杂志

Objective:To investigate five kinds of tuberculin skin test (TST), tubercle bacillus-antibody(TB-Ab), interferon-γ release assay(IGRA), tubercle bacillus-DNA (TB-DNA) and collection of bacterial centrifugal smears methods, the application value of combined detection in improving the diagnostic efficiency of pneumoconiosis complicated with tuberculosis.Methods:A total of 150 eligible patients with pneumoconiosis from January 2018 to January 2019 in Zhangjiakou Pulmonary Hospital were selected as the research subjects, and all of them underwent TST, TB-Ab, IGRA, TB-DNA and bacterial centrifugal smear detection. Compared the positive rates of five detection methods in pneumoconiosis and its different stages, and compare the proportion of tuberculosis infection and tuberculosis in different stages of pneumoconiosis.Results:Among the 150 patients with pneumoconiosis, 41 cases (27.33%) were with pneumoconiosis complicated with tuberculosis infection, 24 cases (16.00%) with pneumoconiosis complicated with clinically diagnosed pulmonary tuberculosis, 21 cases (14.00%) with pneumoconiosis complicated with confirmed pulmonary tuberculosis, and 45 cases (30.00%) with pneumoconiosis complicated with pulmonary tuberculosis; with the improvement of pneumoconiosis stage, the proportion of pneumoconiosis combined with tuberculosis infection and pulmonary tuberculosis increased significantly ( P<0.05). Compared with TB-Ab, TB-loop-mediated isothermal amplification(LAMP), and interlayered cup collection centrifuge smear method, the overall positive rate of IGRA detection and pneumoconiosis stage Ⅲ were higher ( P<0.05), but there was no significant difference compared with TST detection ( P>0.05). The positive rate of combined detection was higher, but there was no significant difference compared with IGRA detection ( P>0.05). With the increase of pneumoconiosis stage, the positive reaction intensity of TST decreased, and the positive value of TB-Ab and IGRA increased. Conclusions:The combined detection of TST, TB-Ab, IGRA, TB-DNA and bacterial centrifugal smear method can significantly improve the diagnostic efficiency of pneumoconiosis combined with tuberculosis.

Corrección de la altura patelar en inestabilidad rotuliana / Correction of patellar height in patellofemoral instability

El manejo de la inestabilidad patelofemoral se basa en una adecuada evaluación de alteraciones anatómicas predisponentes. Patela alta es una de las causas más importantes de inestabilidad objetiva. La alteración biomecánica que ésta produce puede conducir a luxación patelar recurrente, dolor y cambios degenerativos focales. El examen físico es fundamental en la toma de decisiones. La evaluación imagenológica ha evolucionado desde métodos basados en radiografía hacia mediciones en resonancia magnética, que permiten una orientación más acabada de la relación existente entre la rótula y la tróclea femoral. El tratamiento se fundamenta en la corrección selectiva de los factores causales, donde la osteotomía de descenso de la tuberosidad anterior de la tibia y la reconstrucción del ligamento patelofemoral medial son herramientas que deben considerarse racionalmente. Este artículo realiza una revisión de la literatura, otorgando los fundamentos quirúrgicos que explican la importancia del tratamiento específico de patela alta en inestabilidad rotuliana.

Patellofemoral instability management is based on a thorough evaluation of predisposing anatomical factors. Patella alta is one of the utmost causes of objective instability. As a result, biomechanical disturbance can lead to recurrent patellar instability, pain, and focal degenerative changes. Physical examination is paramount in decision making. Imaging evaluation has evolved from X-rays based methods to magnetic resonance measurements, which allows a more accurate assessment of the patellotrochlear relationship. Treatment is based on a selective risk factors correction, where tibial tubercle distalization osteotomy and medial patellofemoral ligament reconstruction must be considered altogether. This article reviews the surgical rationale of patella alta treatment in patellofemoral instability.

Classification of peroneal muscle trochlear and its correlation with calcaneus / 解剖学报

Objective To measure and classify the trochlear size of fibular muscle, and to analyze its correlation with calcaneus. Methods In 824 calcaneal specimens, the length, width and height of the peroneal muscle trochlear were measured and classified according to the four types of flat, convex, concave and tunnel. Results The prevalence of the peroneal tubercle was 62. 5%. The average length, width, and height of the tubercle were ( 11.5±3.32) (2.56-23.14) mm, (6.27±2.20) (1.34-14.99)mm, and (2.69±1.30) (0.41-8.18)mm respectively. The four types of peroneal tubercle were classified as flat in 191 (37.09%), prominent in 189 (36.7%), concave in 131 (25.44%), and tunnel in 4 (0.77%). Conclusion This data may help understand pathology of peroneus tendon and its relationship with peroneal tubercle, and it may help make standard to define the abnormal peroneal tubercle.

Clinical implications in orbital and pterional flap surgeries as well as radioimaging studies to determine topographical prevalence and characterization of meningo-orbital foramen in orbits of the Indian population / Implicaciones clínicas en cirugías de colgajo orbitario y pterional, así como estudios de radioimagen para determinar la prevalencia topográfica y la caracterización del foramen meningoorbitario en órbitas de la población india

SUMMARY: The pear-shaped bony orbit connects with intracranial cavity via foramina's and fissures. The Meningo-orbital Foramen (MOF) is usually present in greater wing of sphenoid close to lateral edge of Superior orbital fissure. It provides a route for an anastomosis between the orbital branch of the middle meningeal artery (MMA) and recurrent meningeal branch of Ophthalmic Artery (OA) and hence, risk of damage during surgeries can occur. To verify occurrence and location, with morphology of MOF in dry orbits and the impending clinical hazards in surgeries pertaining to the orbit, document and analysis it to determine a standardized guideline. The presence for MOF was studied in 446 dry orbits with its location from the supra orbital margin (SOM), front zygomatic suture (FZS), the lateral tubercle of Whitnall (WT)and the lateral end of superior orbital fissure (SOF) along with its patency, laterality and number of foramina's present. Nylon probes, long divider/pins, compass and Vernier callipers was used to check the patency and various parameters. The study noted the percentage prevalence of MOF as 69 % with communication with middle cranial fossa (MCF) being 76 % of 69 % and the average distance from SOM, FZS, WT and lateral end of SOF being 35.58 mm, 24.9 mm, 26.6 mm and 0.92 mm. On comparison with various population studies, certain similarities and differences with regards to different parameters were noted. Prevalence of MOF was mostly unilateral and showed multiple foramina, that can act as channels for arteries, a variant of MMA or OA, that supply orbital structures or tumour growths. Thus, awareness of this variation is of prime importance to ophthalmologists and neurosurgeons as well as interventional radiologists, in preventing haemorrhagic condition which could further raise the difficulties in operative procedures and surgical outcomes.

RESUMEN: La órbita ósea en forma de pera se conecta con la cavidad intracraneal a través de forámenes y fisuras. El foramen meningoorbitario (MOF) suele estar presente en el ala mayor del esfenoides cerca del margen lateral de la fisura orbitaria superior. Proporciona una ruta para una anastomosis entre la rama orbitaria de la arteria meníngea media (MMA) y la rama meníngea recurrente de la arteria oftálmica (OA) y, por lo tanto, puede ocurrir riesgo de daño durante las cirugías. Para verificar la ocurrencia y ubicación, con la morfología de MOF en órbitas secas y los peligros clínicos inminentes en cirugías de la órbita, documentarlo y analizarlo para determinar una pauta estandarizada. Se estudió la presencia de MOF en 446 órbitas secas desde el margen supraorbitario (MOS), sutura cigomática frontal (FZS), el tubér- culo lateral de Whitnall (WT) y el extremo lateral de la fisura orbitaria superior (SOF) junto con su permeabilidad, lateralidad y número de forámenes presentes. Se utilizaron sondas de nailon, divisores / pasadores largos, brújula y calibradores Vernier para comprobar la permeabilidad. En el estudio se pudo observar que la prevalencia porcentual de MOF era del 69 %, siendo la comunica- ción con la fosa craneal media (MCF) del 76 % del 69 % y la distancia promedio desde SOM, FZS, WT y el extremo lateral de SOF era de 35,58 mm, 24,9 mm, 26,6 mm y 0,92 mm. En comparación con varios estudios de población, se observaron ciertas similitudes y diferencias con respecto a diferentes parámetros. La prevalencia de MOF fue mayoritariamente unilateral y mostró múltiples forámenes, que pueden actuar como canales para las arterias, una variante de MMA u OA, que irrigan estructuras orbitarias o crecimientos tumorales. Por lo tanto, la conciencia de esta variación es de primordial importancia para los oftalmólogos y neurocirujanos, así como para los radiólogos intervencionistas, en la prevención de una enfermedad hemorrágica que podría aumentar aún más las dificultades en los procedimientos y los resultados quirúrgicos.

Anatomía quirúrgica de la vena tiroidea media: prevalencia en 100 tiroidectomías totales consecutivas / Surgical anatomy of the median thyroid vein: prevalence in 100 consecutive total thyroidectomies

El estudio de las venas tiroideas no ha recibido una investigación tan exhaustiva como lo tuvieron las arterias tiroideas y los nervios laríngeos en relación a la cirugía tiroidea.De los tres pedículos venosos de la glándula tiroides, el medio, de lejos es el menos estudiado. La vena tiroidea media es inconstante y es el primer elemento vascular de la glándula tiroides que debe ser seccionado antes de luxar el lóbulo hacia medial para evaluar sus relaciones posteriores. Su lesión puede provocar sangrado intraoperatorio dificultando secundariamente la identificación del nervio laríngeo inferior y las glándulas paratiroides, próximas a la misma. Se realizó un estudio descriptivo de corte transversal evaluando la pesencia, número, simetría y asociación de la vena tiroidea media con variables tales como edad y sexo del paciente, así como la hiperfuncionalidad de la glándula tiroides y la presencia del tubérculo de Zuckerkandl en 100 tiroidectomías totales llevadas a cabo en el Instituto Nacional del Cáncer y en el Servicio de Otorrinolaringología del Hospital Central del Instituto de Previsión Social del Paraguay. La prevalencia global de vena tiroidea media fue del 74 %. En el lóbulo derecho, la vena se presentó en el 60 %, mientras que en el lóbulo izquierdo en el 53 %. En el 38 % se encontró la vena en ambos lóbulos. En 4 pacientes se localizaron venas tiroideas medias dobles, en una de ellas fue bilateral. El mayor porcentaje de las venas tiroideas medias se originó en el tercio medio del lóbulo, el 72 % en el lado derecho y el 70% en el izquierdo. No se encontró asociación entre la presencia de la vena tiroidea media y la edad, sexo, estado de hiperfunción glandular, así como tampoco con la presencia del tubérculo de Zuckerkandl.

The study of the thyroid veins has not received an investigation as extensive as the thyroid arteries and laryngeal nerves did in relation to thyroid surgery. Of the three veins pedicles of the gland the middle is far the least studied. This vein is inconstant and is the first vascular element of the gland that must be sectioned before the medial lobe is dislocated to evaluate ist posterior relationships. His injury can cause intraoperative bleeding, making it difficult to identify the inferior laryngeal nerve and the parathyroid glands, proximal to it. A descriptive crossseccional study was carried aot evaluating the presence, number, symmetricity and association of the middle thyroid vein with variables such as age and sex of the patient, as well as the hyperfunctionality of the gland and the presence of the Zuckerkandl tubercle in 100 total thyroidectomies undergoing at the National Cancer Institute and the ENT Service of the Social Security Institute´s Central Hospital. The overall prevalence of the middle thyroid vein was 74%. In the right lobe the vein appeared in 60% while in the left lobe in 53 %. Double middle thyroid vein was found in 4 patients, in one of them it was bilateral. The highest percentage of the middle thyroid veins originated in the middle third of the lobe, 72 % on the right and 70% on the left side. No association was found between the presence of the vain and age and sex, the state of glandular hyperfunstion, as well as the presence of Zuckerkandl tubercle.

Femoral Nerve in Femoral Triangle: A Morphometric Study with Clinical Relevance

Background: Femoral nerve is a nerve of choice forfemoral nerve blockade. It enters the femoral triangle atthe midinguinal point. However, this point of entry neednot be the same always. Aim and Objectives: This studyis aimed at measuring the morphometry of the femoralnerve with the help of bony landmarks. Material andmethods: Forty adult lower limbs were dissected andthe morphometry of the femoral nerve was studied.Results: The mean distance from the Anterior SuperiorIliac Spine (ASIS) to the pubic tubercle was 12.66 ±1.48 cm. We found the FN from the ASIS at a meandistance of 6.38 ± 1.45 cm. Also, the FN was at a meandistance of 6.76 ± 1.12 cm from the pubic tubercle. Themean length of the FN trunk below the inguinalligament, i.e., in the femoral triangle before the divisionwas 2.19 ± 0.34 cm. However, in 8 lower limbs, the FNtrunk was divided before entering the femoral triangle.Conclusion: The findings of our study serve as anenabling guide to the surgeons, neurologists andanesthetist's in detecting the FN for various clinical andsurgical procedures.

Role of low-lying pubic tubercle in the development of inguinal hernia

Background: Hernia is defined as abnormal protrusion of whole or a part of a viscus through the wall that contains it. Among all external abdominal hernias, inguinal hernia is one most commonly encountered. Many factors are responsible for the formation of the inguinal hernia but, what makes a few people more susceptible to this situation is still clearly not proved. The lowness of pubic tubercle is associated with narrow origin of internal oblique muscle from lateral inguinal ligament which fails to protect the deep inguinal ring consequently lead to inguinal hernia.Methods: The study was conducted in Sardar Patel Medical College and attached hospital, Bikaner for duration of 12 months from March 2018 to February 2019. It is a case-control study with 50 cases and 50 control meeting inclusion criteria. In all patients, following parameters SS line, ST line, height, weight was recorded and evaluated.Results: The mean value of ST line in our study group is 7.37±0.182 cm which is significantly greater (p=0.0001) than the controls the mean value being 7.01±0.262 cm. In our study, 98% of cases were having ST line >7.01 cm whereas 66% of controls were ST line under 7.01 cm.Conclusions: Group of people with low lying pubic tubercle are at high risk of developing inguinal hernia.

Tubérculo marginal del hueso cigomático / Marginal tubercle of zygomatic bone

El hueso cigomático, ubicado en la parte superior y lateral de la cara, es un hueso par e irregular con forma cuadrilátera o romboidal. Se describen 2 caras, 4 aristas y 4 ángulos, forma cavidades, permite la inserción muscular y aponeurótica, es parte de la arquitectura facial, distribuye las fuerzas masticatorias y permite el paso del nervio cigomático. Su margen postero-superior presenta una prominencia ósea conocida como tubérculo marginal, en el que se observa la inserción de la fascia temporal. El objetivo de este trabajo fue describir las características particulares de esta prominencia. La muestra correspondió a 30 cráneos de adultos chilenos de ambos sexos. A través de una serie de puntos óseos, se describió la presencia, ubicación, tamaño, forma, cortical y trabeculado del tejido óseo del tubérculo marginal. Para realizar las mediciones se utilizaron cámara digital, compas de precisión y cáliper digital. El análisis radiográfico requirió tomografía computarizada de alta resolución. Los resultados mostraron que el tubérculo marginal del hueso cigomático es una prominencia constante, ubicada en el tercio medio del proceso frontal del hueso y que la mayoría de los individuos mostraron una forma semilunar. Su altura fluctúa entre 3 y 4 mm, siendo más pronunciada en hombres que en mujeres. El grosor de la corteza ósea es directamente proporcional a la prominencia del tubérculo, mientras que el trabeculado esponjoso está inversamente relacionado con este último. El análisis de estos resultados parece indicar que las fuerzas biomecánicas ejercidas por la musculatura masticatoria y transmitidas por la fascia temporal, determinan la morfología externa e interna de esta prominencia y del propio hueso cigomático. Concluimos, declarando la necesidad de revisar el conocimiento anatómico a la luz de las nuevas técnicas de imagen e integración disciplinar.

The zygomatic bone, located in the upper and lateral area of the face, is an even and irregular quadrilateral or rhomboid shaped bone. It presents 2 faces, 4 margins and 4 angles. It forms cavities, allows muscular and aponeurotic insertion, is part of the facial architecture, distributes masticatory forces and allows the passage of the zygomatic nerve. Its postero-superior margin presents a bony prominence known as a marginal tubercle, in which the insertion of the temporal fascia is observed. The objective of this work was to describe the particular characteristics of this prominence. The sample corresponded to 30 skulls of Chilean adults of both sexes. Through a series of bone points, the presence, location, size, shape, cortical and trabeculate of the bone tissue of the marginal tubercle was described. A digital camera, precision compass and digital caliper were used to perform the measurements. The radiographic analysis required high-resolution computed tomography. The results showed that the marginal tubercle of the zygomatic bone is a constant prominence, located in the middle third of the frontal process of the bone and that most individuals showed a semilunar shape. Its height fluctuated between 3 and 4 mm, being more pronounced in men than in women. The thickness of the bone cortex was directly proportional to the prominence of the tuber, while the spongy trabeculate was inversely related to the latter. The analysis of these results seems to indicate that the biomechanical forces exerted by the masticatory musculature and transmitted by the temporal fascia, determine the external and internal morphology of this prominence, and of the zygomatic bone itself. In conclusion, it is recommended to review anatomical knowledge in the light of new imaging techniques and disciplinary integration.

Separate thyrothymic thyroid remnant; clinically crucial anatomic variation

PURPOSE: The anatomical variations of the thyroid gland including separate thyroidal remnant at the thyrothymic area are of significance during thyroid surgery for “total” thyroidectomy, and for recurrent goitre. In the present study, we aimed to detect the separate rests of thyroidal tissue in the thyrothymic region.METHODS: The thyrothymic region was explored for identification, dissection, and excision of separate thyroidal remnants in 134 patients who underwent primary thyroid surgery. In this series, we studied the incidence and anatomical features of the thyrothymic remnant and its relation with other embryologic remnants.RESULTS: Overall, 222 sides of the thyroid were explored in this study. An entirely separate thyrothymic remnant of the thyroid was identified and excised in 8 of 134 patients (6%). Mean size of removed remnants was 36.4 mm (range, 29–45 mm) in diameter. The incidences of pyramidal lobe (PL) and Zuckerkandl's tubercle (ZT) were 71.6% and 59.7%, respectively. The thyrothymic remnant coexisted with PLs in 4 patients. Four patients had all 3 embryologic remnants: thyrothymic remnant, PLs, and ZTs.CONCLUSION: An entirely separate thyroidal remnant at the thyrothymic area is not a rare variation. The considerably large size of a remnant may threaten the completeness of thyroidectomy and may result in recurrence if it is left behind after thyroid surgery. Awareness, identification, and excision of the separate remnant at the thyrothymic area and the other embryologic remnants are critical for ensuring completeness of thyroidectomy and preventing recurrences.

Fractura del tubérculo medial de la apófisis posterior del astrágalo / Medial tubercle's fracture of posterior process of talus

OBJETIVO Mostrar una fractura infrecuente del tubérculo posteromedial del astrágalo diagnosticado y tratado de manera aguda mediante osteosíntesis con tornillo Acutrak® (2014 Acumed® LLC). MATERIAL Y MÉTODOS Varón de 28 años, que acude a Urgencias tras torcedura de tobillo con dolor al mover tobillo y hallux y tumefacción en cara interna. En Urgencias pasó desapercibida. En consulta a la semana refería sensación de que se le engancha el primer dedo con la flexoextensión. Se observa fractura del tubérculo medial de la apófisis posterior del astrágalo con desplazamiento >3mm y clínica de posible interposición del flexor hallucis longus. Se decidió tratamiento quirúrgico con tornillo Acutrak®. Se inmovilizó con férula 3 semanas y descarga 6 semanas. RESULTADOS A los 8 meses balance articular completo, sin dolor ni limitación para las ABVD y sin clínica de atrapamiento del flexor del hallux. Como complicación aguda, se verificó infección de herida quirúrgica que se trató con antibióticos. DISCUSIÓN Ese tipo de fracturas son infrecuentes. El mecanismo lesional suele ser dorsiflexión-pronación. Es importante un diagnóstico temprano y para ello es necesario una alta sospecha diagnóstica. Para su diagnóstico, son necesarias radiografías anteroposterior y lateral y si no se visualiza la lesión, proyección oblicua con 30°- 40° de rotación externa. En casos agudos resulta de utilidad la TAC y en casos crónicos la RM. CONCLUSIÓN Aunque generalmente el tratamiento es conservador, en ocasiones puede ser necesario la cirugía mediante osteosíntesis o exéresis del fragmento cuando la fractura provoca impingement.

OBJECTIVE Show an infrequent fracture of the posteromedial tubercle of the talus diagnosed and treated acutely by Acutrak® screw (2014 Acumed® LLC) osteosynthesis. MATERIAL AND METHODS A 28-year-old man attended the Emergency Department after spraining his ankle with pain when moving his ankle and hallux and swelling on the internal face. In the ER it went unnoticed. A week later in the clinic, he refered to the sensation that the first finger is hooked with the flexion extension. A fracture of the medial tubercle of the posterior process of the talus is observed with a displacement of > 3 mm and clinical signs of possible interposition of the hallucis longus . Surgical treatment with Acutrak® screw was made. He was immobilized with a splint for 3 weeks and discharge for 6 weeks. RESULTS At 8 months complete joint balance, without pain or limitations for BADL and without hallux flexor entrapment symptoms. As an acute complication, surgical wound infection that was treated with antibiotics. DISCUSSION These types of fractures are rare. The injury mechanism is usually dorsiflexion-pronation. Early diagnosis is important and a high diagnostic suspicion is required. Anteroposterior and lateral radiographs are necessary for its diagnosis and if the lesion is not visualized, oblique projection with 30°- 40° external rotation. CT is useful in acute cases and MRI in chronic cases. CONCLUSION Although the treatment is conservative, surgery may sometimes be necessary by means of osteosynthesis or excision of the fragment when the fracture causes impingement.

Clasificación del tubérculo suprameatal y análisis morfométrico con enfoque quirúrgico del hueso temporal / Classification of the suprameatal tubercle and morphometric analysis with a surgical approach to the temporal bone

Introducción: El hueso temporal es una estructura valiosa en el abordaje de patologías intracraneales a la fosa media y posterior, requiriendo en ocasiones la realización de petrosectomías anteriores, posteriores o abordajes combinados para la resección de tumores en dichas regiones. El propósito del presente estudio es realizar análisis morfométrico con enfoque quirúrgico del hueso temporal, en cráneos adultos, con énfasis en el tubérculo suprameatal (TSM) teniendo en consideración sus relaciones anatómicas. Material y métodos: El presente estudio se realizó en las instalaciones de la Facultad de Medicina de la Universidad Nacional Autónoma de México (UNAM). Se analizaron 200 huesos temporales de 100 cráneos humanos adultos. Se dio énfasis al TSM de acuerdo a su ubicación y tamaño, clasificándolo en: anterior medio o posterior y en tipo I (0-1 mm), tipo II (2-3 mm) y tipo III (>3 mm). Además, se realizaron mediciones con enfoque quirúrgico de la porción petrosa del hueso temporal y de la cresta supramastoidea. Resultados: El TSM se observó en 171 especímenes estudiados (85.5%). Entre ellos, la posición posterior fue la más frecuente 85 de 171 (49.70%), seguida de la posición media 43 (25.14%) y por último la posición anterior 43 (25.14%). En cuanto al tamaño, se encontró con mayor frecuencia el tipo II en 99 de los especímenes (49.5%), el tipo I en 82 especímenes (41%) y tipo III en 19 (9.5%). El asterion se reflejó dentro de la impresión de los senos en la mayoría 48.5%, la unión de la cresta supramastoidea con sutura escamosa se reflejaba en 98.5% de los casos a la fosa media. Discusión: En nuestra búsqueda de información no se cuenta con datos para realizar comparación con la obtenida en este estudio del tubérculo suprameatal, el hallazgo encontrado parece indicar que se encuentra una relación directa con la presencia de la impresión del surco del seno petroso superior. La distribución de acuerdo a su posición reviste importancia cuando se encuentra en grado III puesto que plantea una dificultad técnica, en abordajes como en petrosectomías, o bien, al cavum de Meckel desde un abordaje retrosigmoideo. Conclusión: La observación anatómica y clasificación que realizamos del tubérculo suprameatal, una estructura muy poco evaluada, nos da una consideración preoperatoria y transoperatoria cuando realizamos abordaje que involucra la cara posterior de la porción petrosa del hueso temporal

Introduction: The temporal bone is a valuable structure in the approach of intracranial pathologies to the middle and posterior fossa. Sometimes requiring the performance of petrosectomies or combined approaches for the resection of tumors in these regions. The purpose of this study is to perform morphometric analysis in adult skulls with a surgical approach to the temporal bone, with emphasis on the suprameatal tubercle (SMT) taking into account their anatomical relationships. Material and methods: The present study was carried out in the facilities of the Faculty of Medicine of the National Autonomous University of Mexico (UNAM). 200 temporal bones from 100 adult human skulls were analyzed. The SMT was emphasized according to its location and size, classifying it as: anterior, middle, or posterior and type I (0-1 mm), type II (2-3 mm) and type III (> 3mm). In addition, measurements were made with a surgical approach of the petrosal portion of the temporal bone and the supramastoid crest. Results: The SMT was observed in 171 specimens studied (85.5%). Among them, the posterior position was the most frequent 85 of 171 (49.70%), followed by the middle position in 43 (25.14%) and finally the anterior position in 43 (25.14%). In terms of size, type II was more frequently found in 99 of the specimens (49.5%), type I in 82 specimens (41%) and type III were found in 19 (9.5%). The asterion was reflected within the impression of the sinuses in the majority 48.5%, the union of the supramastoid crest with squamous suture was reflected in 98.5% of the cases to the middle fossa.Discussion: In our search for information, there is no data to make a comparison with that obtained in this study of the suprameatal tubercle. The findings seems to indicate that there is a direct relationship with the presence of the impression of the groove of the upper petrosal sinus. The distribution according to its position is important when it is in grade III since it poses a technical difficulty, in approaches such as petrosectomies, or approach to Meckel's cave from a retrosigmoid approach. Conclusion: The anatomical observation and classification that we perform of the suprameatal tubercle, a very poorly evaluated structure, gives us a preoperative and transoperative consideration when we perform an approach that involves the posterior aspect of the petrosal portion of the temporal bone

Tubérculo de Gerdy: una estructura olvidada en la terminología anatómica internacional / Gerdy's tubercle: a forgotten structure in the international anatomical terminology

En la enseñanza de la anatomía, el uso de los epónimos es cada vez más escaso, sin embargo su uso aún es evidente incluso en la literatura actualizada, en este caso el uso del epónimo se acompaña generalmente del término correcto según la Terminología Anatómica Internacional (TAI). El denominado "Tubérculo de Gerdy" (TG) es un epónimo ampliamente usado en la literatura y la comunidad científica para denominar un reparo óseo ubicado en el cóndilo lateral de la tibia, corresponde a un referente anatómico y clínico importante para inserción de músculos, ligamentos y procedimientos medicoquirúrgicos de la rodilla. A pesar de esta amplia denominación, y en comparación con otros epónimos, la TAI no la incluye y no relaciona algún término oficial con esta estructura anatómica. El objetivo del trabajo fue revisar libros usados en la enseñanza de la anatomía y artículos científicos actualizados para ver la presencia y descripción de esta estructura a fin de proponer un término que se ajuste a los principios básicos de la Terminología Anatómica Internacional en concordancia con la tarea del Programa Federativo Internacional de Terminología Anatómica (FIPAT), organismo de la Federación Internacional de Asociaciones de Anatomistas (IFAA). El TG se describe como una estructura ubicada entre la tuberosidad de la tibia y la cabeza de la fíbula, refiriéndose a él con sinónimos como tubérculo del músculo tibial anterior, tubérculo del músculo tensor de la fascia lata, tubérculo del tracto iliotibial y tubérculo anterolateral de la tibia. En revistas morfológicas aparece en artículos actuales relacionados al ligamento anterolateral. Según la descripción de la literatura proponemos como término anatómico para esta estructura "Tuberculum anterolateralis tibiae", cuya traducción es usada como sinónimo por otros autores, ajustándose así a los principios básicos de la TAI. Pretendemos que estos antecedentes sean discutidos por los expertos que conforman el FIPAT.

In teaching anatomy, the use of eponyms is increasingly scarce. Nonetheless, eponyms remain evident in updated literature, in this case the use of the eponym is accompanied by the correct term according to the International Anatomical terminology (TAI) Gerdy´s tubercle (GT) is an eponym widely used in the literature and scientific community to name a lateral tubercle of the tibia. It is an insertion site of muscles and ligaments and an important anatomical reference in knee surgical procedures. Despite its importance, it is not included in the International Anatomical Terminology (IAT) and an official name for this structure is lacking. The aim of this work was to review classic books used in the anatomy teaching and recent scientific papers, and further, to propose an anatomical term for the Gerdy tubercle that fit IAT basic principles, in agreement with the International Federal Program of Anatomical Terminology (IFPAT), and organism that is part of the International Federation of Anatomist Associations (IFAA). The TG is described as a structure located between the tuberosity of the tibia and the head of the fibula, referring to it with synonyms such as tubercle of the anterior tibia, tubercle of the tensor fascia lata, tubercle of iliotibial tract and anterolateral tibial tubercle. In morphological journals it appears in current articles related to the anterolateral ligament. We propose as an anatomical term for the Gerdy´s tubercle the name of "Tuberculum anterolteralis tibiae" its translation is used as a synonym by other authors and fits the basic principles of TAI. We hope that this information be considered by the experts that make up the FIPAT.

Combined operation involving tibial tubercle distalization for recurrent patellar dislocation with patella alta / 中国修复重建外科杂志

Objective: To explore the clinical effects of combined operation involving tibial tubercle distalization for the recurrent patellar dislocation with patella alta. Methods: Between April 2010 and May 2016, 14 cases of recurrent patellar dislocation with patella alta were treated with combined operation involving tibial tubercle distalization. There were 5 males and 9 females with an average age of 18.5 years (range, 13-26 years). The left knee was involved in 9 cases and the right knee in 5 cases. The patella had dislocated 3.3 times on average (range, 2-5 times). The interval between the first dislocation and admission was 19.7 months on average (range, 4-60 months), and the main symptoms were knee pain and limited knee movement. Preoperative X-ray films, CT, and MRI examinations of knee joint showed that the epiphyseal plate closed in all patients. Of all patients, 3 patients had avulsion fracture of the inner edge of patella, and 2 patients had free body in articular cavity. The tibial tuberosity-trochlear groove (TT-TG) distance, patellar-trochlear-groove distance, Caton-Deschamps index, knee range of motion (ROM), Lysholm score, International Knee Documentation Committee (IKDC) score, Kujala score, and Tegner score were compared pre- and post-operation. Results: All patients had primary wound healing. All patients were followed up 24-72 months with an average of 34.6 months. X-ray film and CT examination showed that the patellar dislocation was corrected and the osteotomy of the tibial tubercle healed with an average healing time of 3.8 months (range, 3-5 month). At 1 day and 1 year after operation, the TT-TG distance, patellar-trochlear-groove distance, and Caton-Deschamps index showed significant differences when compared with preoperative values ( P0.05). At the 1 year and 2 years after operation, the knee ROM, Lysholm score, IKDC score, Kujala score, and Tegner score showed significant differences when compared with preoperative values ( P0.05). Conclusion: Combined operation involving tibial tubercle distalization is a safe and reliable method, which has satisfactory short-term effectiveness for the recurrent patellar dislocation with patella alta.

Assessment of tubercle bacilli in various organs by staining and polymerase chain reaction technique

Background: Early diagnosis of tuberculosis (TB) by different clinical methods plays a major role in control of TB in early stages. The present study was done with the aim to assess and compare the efficiency of staining techniques and polymerase chain reaction (PCR) for detection of tubercle bacilli in various organs.Methods: The study included data 14,472 patients of both prospective (during March 2008 to 2009) and retrospective cases (past one year of the study period). For prospective cases the cytological material for the study was collected by fine needle aspiration cytology (FNAC). For retrospective cases of past one year were retrieved from the records. TB suspected cases were evaluated by Ziel-Nelson (ZN), Auramine-Rhodamine (A-R) staining techniques and by PCR.Results: Total 284 cases were diagnosed with TB in various organs. In them, epithelioid granuloma was seen 227 cases (79.92%) and Langhans giant cells were seen in 18 cases (6.34%). AFB positivity on ZN staining was observed in 161 cases (56.69%) and 9 cases (3.16%) showed positivity for tubercle bacilli on A-R staining. PCR was done in 20 prospective cases and total percentage of positivity by PCR was seen in 18 cases (90%).Conclusions: The total percentage positivity for detection of tubercule bacilli by PCR assay was found to be more (90%) with high sensitivity and specificity compared to ZN (56.6%) and AR staining techniques (3.16%).

Tibial tubercle fracture associated with distal rupture of the patellar tendon: case report / Fratura da tuberosidade anterior da tíbia associada à ruptura distal do tendão patelar: relato de caso

ABSTRACT Avulsion of the tibial tubercle is an uncommon injury that occurs in the young athlete, resulting from an eccentric contraction of the extensor mechanism with the leg fixed to the ground. Concomitant injuries to the patellar tendon are very rare, with few cases reported in the literature. The authors present a case of a 15-year-old basketball player who suffered an avulsion of the tibial tubercle associated with complete distal rupture of the patellar tendon while training. It was treated with open reduction of the tibial fragment and reconstruction of the patellar tendon with mini-anchors and cannulated screws, as well as hamstring autograft tendon reinforcement. The patient showed excellent results and returned to sports after 12 months of follow-up.

RESUMO A fratura-avulsão da tuberosidade anterior da tíbia é uma lesão incomum que ocorre no jovem atleta, resultado de uma contração excêntrica do mecanismo extensor do joelho com o membro inferior fixo ao solo. Lesões concomitantes ao tendão patelar são muito raras, com poucos casos relatados na literatura. Os autores apresentam o caso de um atleta de basquete de 15 anos que sofreu uma fratura-avulsão da tuberosidade anterior da tíbia associada à ruptura completa distal do tendão patelar durante movimento de arremesso no treino esportivo. O paciente foi tratado com redução aberta da fratura e reparo do tendão patelar com miniâncoras e parafuso poste com reforço tendinoso com enxerto autólogo de semitendíneo. O paciente apresentou ótimos resultados e retornou ao esporte após 12 meses de acompanhamento.

Anatomy and clinical importance of the extracranial clivus and surrounding structures / Anatomía e importancia clínica del clivus extracraneal y las estructuras circundantes

The aim of this study was to reveal the clinical importance of measurements taken from the pharyngeal tubercle (PT) to various anatomical structures around the extracranial clivus. Twenty-six adult dry Anatolian skulls were examined. The extracranial clivus and PT were used as landmarks from which various distances were measured using a digital caliper accurate to 0.01 mm. The following mean distances from the PT were observed; foramen lacerum (FL) (L: 17.15 mm, R: 17.4 mm) ; medial external margin of the carotid canal (CC) (L: 26.7 mm, R: 27.5 mm); anterior tip of occipital condyle (OC) (L: 16.4 mm, R: 16.3 mm); anterior margin of foramen magnum (FM) (10.8 mm); foramen ovale (FO) (L: 25.9 mm, R: 29.1); medial margin of the jugular fossa (JF) (L: 25.4 mm, R: 25.7 mm); medial external margin of the hypoglossal canal (HC) (L: 20.0 mm, R: 19.9 mm). Mean bilateral distances were: LFO-RFO: 45.34 mm; LFL-RFL: 20.1 mm; LCC-RCC: 52.1 mm; LOC-ROC: 17.6 mm; LJF-RJF: 45.2 mm; LHC-RHC: 33.5 mm. The following mean distances were observed from the FM: FM-OC (L: 8.3 mm, R: 9.3 mm); FM-HC (L: 17.8 mm, R: 17.4 mm). Also the mean distance of OC-HC were observed (L: 11.7 mm, R: 11.4 mm). Present measurements suggest that the PT can be used as an anatomical landmark during surgery involving clival pathology. However, the anatomy and variations of the extracranial clivus and surrounding structures must be taken into consideration.

El objetivo de este estudio fue revelar la importancia clínica de las mediciones tomadas desde el tubérculo faríngeo (TF) a diversas estructuras anatómicas alrededor del clivus extracraneal. Veintiséis cráneos, secos adultos, de Anatolia, fueron examinados. El clivus extracraneal y TF se utilizaron como puntos de referencia a partir de los cuales se midieron varias distancias con un calibrador digital con una precisión de 0,01 mm. Se observaron las siguientes distancias medias del TF: foramen lacerum (FL) (L: 17.15 mm, R: 17,4 mm); margen externo medial del canal carotídeo (CC) (L: 26,7 mm, R: 27,5 mm); parte anterior del cóndilo occipital (OC) (L: 16,4 mm, R: 16,3 mm); margen anterior del foramen magnum (FM) (10,8 mm); foramen oval (FO) (L: 25,9 mm, R: 29,1); margen medial de la fosa yugular (FY) (L: 25,4 mm, R: 25,7 mm); margen medial del canal hipogloso (CH) (L: 20,0 mm, R: 19,9 mm). Las distancias bilaterales medias fueron: LFO-RFO: 45,34 mm; LFLRFL: 20,1 mm; LCC-RCC: 52,1 mm; LOC-ROC: 17,6 mm; LJFRJF: 45,2 mm; LHC-RHC: 33,5 mm. Se observaron las siguientes distancias medias de la FM: FM-OC (L: 8,3 mm, R: 9,3 mm); FMCH (L: 17,8 mm, R: 17,4 mm). También se observó la distancia media de OC-CH (L: 11,7 mm, R: 11,4 mm). Las mediciones actuales sugieren que el TF puede ser utilizado como un hito anatómico durante la cirugía que involucra la patología clival. Sin embargo, se deben tener en cuenta la anatomía y las variaciones del clivus extracraneal y las estructuras circundantes.

A hypertrophied peroneal tubercle can present as a bony prominence at the lateral aspect of the foot and a peroneal tenosynovitis or tear. We report a case of a 52-year-old man complaining of lateral foot tingling pain and numbness. The sural nerve entrapment and peroneus longus tenosynovitis by hypertrophied peroneal tubercle were confirmed. Good results were obtained after excision of the hypertrophied peroneal tubercle and sural nerve release.

A Case of Eyelid Desmoplastic Trichilemmoma

PURPOSE: Desmoplastic trichilemmoma is a rare variant of trichilemmoma first described in 1990. Desmoplastic trichilemmoma on the eyelid has not been previously reported in Korea. We report our experience with a case of desmoplastic trichilemmoma of the eyelid. CASE SUMMARY: A 72-year-old male patient presented with a round mass on the upper eyelid, which was noticed 1 year prior and caused irritation and itching. Excisional biopsy of the mass was performed. Histopathological examination revealed findings suggestive of a desmoplastic trichilemmoma. There was no local recurrence during the 2-year follow-up. CONCLUSIONS: Desmoplastic trichilemmoma should be considered when determining the type of eyelid mass.
