Clinical characteristics of acute acquired concomitant esotropia among different age groups / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To analyze the clinical characteristics of acute acquired concomitant esotropia(AACE)in patients among different age groups.METHODS: Retrospective analysis of clinical data. A total of 112 non-Swan type AACE patients who underwent surgery at Peking University People's Hospital from January 2015 to December 2022 were retrospectively analyzed. Clinical data were collected and the characteristics were compared, including gender, age, diopter, duration of disease, daily time spent on near work, angles of deviation before and after surgery, stereopsis, etc. According to age, patients were divided into three groups: <18 years old group(22 cases), 18-45 years old group(67 cases), and >45 years old group(23 cases). The clinical characteristics of patients were compared in each group.RESULTS: A total of 112 patients were included in the study, comprising 56 males and 56 females, with a median age of 29.50(19.25, 41.75)years old. Among them, 97 patients had myopia(86.6%). There were 93 patients(83.0%)who spent more than 8 h on near work. The age group <18 years old had the shortest duration before surgery, with a median time of 1.00(0.50, 1.00)a, the minimum negative diopter, with a median diopter of -0.75(-3.19, -0.56)D in the right eye and the diopter of -1.25(-2.81, -0.75)D in the left eye, and the maximum preoperative near angle of deviation, with a median angle of 30.00(18.50, 80.00)PD, and the maximum preoperative distant angle of deviation, with a median angle of 35.00(23.75, 80.00)PD. All these differences were statistically significant compared with other two groups(both P<0.05). For the age group from 18 to 45 years old, the median near angle of deviation was 20.00(14.00, 30.00)PD, and the median distant angle of deviation was 25.00(20.00, 35.00)PD, both of which were higher than those in the age group >45 years old(both P<0.05). For the age group >45 years old, the median near angle of deviation after surgery was -4.50(-7.50, 0)PD, and the median distant angle of deviation after surgery was 4.50(0, 9.50)PD, which were smaller than those in other two groups(all P<0.05). The age group >45 years old had the hiughest surgical success rate(100%). The preoperative stereopsis was better in age group >45 years old than the group <18 years old(P<0.05). The postoperative stereopsis of the age group of 18 to 45 years old and the age group >45 years old was better than age group <18 years old(both P<0.05).CONCLUSION: Surgical patients with AACE are mainly in the age group from 18 to 45 years old. The characteristic of angle of deviation is that distant angle of deviation is greater than near angle of deviation. The patients <18 years old have larger preoperative angles of deviation than adults, while their stereoacuity is worse than adults in the early postoperative period. It is recommended that augmented-dose surgery should be performed in AACE patients who are in the age group of 18 to 45 years old(5-10 PD). A conservative surgery should be designed for hyperopia young children without established binocular vision.

A comparison between Different Surgical Approaches of Nasopharyngeal Angiofibroma: A Cross-Sectional Observational Study in BSMMU, Bangladesh

Background: The Otolaryngologist is currently dealing with a dramatic problem the nasopharyngeal angiofibroma. The posterolateral wall of the nasal cavity, close to the superior margin of the sphenopalatine foramen, is where the tumor commonly first appeared.Material & Methods:The Otolaryngology & Head Neck Surgery department at Bangabandhu Shiekh Mujib Medical University, Dhaka Medical College Hospital, and Shaheed Suhrawardy Medical College Hospital in Dhaka undertook this retrospective cross-sectional study. The research was done from February 2012 to November 2012. The study’s overall sample size was 30.Results:The majority of individuals (54%) who have nasopharyngeal angiofibroma are between the ages of 16 and 20. the majority of patients have similar symptoms such epistaxis, nasal blockage, nasal discharge, anemia, and masses in the nasal cavity. At presentation, anaemia is present to various degrees in 90% of cases. The lateral rhinotomy method is employed (40%) more often than other approaches. Three blood units were to be transfused into a maximum of 36.66% of the patients throughout the surgery.Conclusion:Nasopharyngeal angiofibroma is currently a difficult issue for otolaryngologists. When endoscopy was used instead of open techniques, we discovered that the mean length of the procedure was shorter, which may be related to endoscopy’s decreased morbidity.

Objective:To investigate the clinicopathological characteristics and prognostic factors of Siewert Ⅱ and Ⅲ adenocarcinoma of esophagogastric junction (AEG).Methods:The retrospetcive cohort study was conducted. The clinicopathological data of 399 patients with AEG who were admitted to Peking University People′s Hospital from January 1998 to December 2015 were collected. There were 318 males and 81 females, aged 66(range, 19-87)years. Observation indicators: (1) clinicopathological characteristics of Siewert Ⅱ and Ⅲ AEG; (2) follow-up and survival; (3) prognostic factors analysis. Patients were followed up by telephone interview and outpatient examination to detect postoperative survival up to December 2018. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Kaplan-Meier method was used to draw survival curves and calculate survival rates. Log-rank test was used for survival analysis. Univariate and multivariate analyses were done using the COX proportional hazard model. Results:(1) Clinicopathological characteristics of Siewert Ⅱ and Ⅲ AEG. Of 399 patients, 198 cases were Siewert Ⅱ AEG and 201 cases were Siewert Ⅲ AEG. There were 130 cases undergoing transthoracic radical AEG surgery, 172 cases undergoing trans-abdominal proximal gastrectomy and 97 cases undergoing transabdominal total gastrectomy. The age, tumor diameter, cases with surgical method as transthoracic radical AEG surgery, transabdo-minal proximal gastrectomy and transabdominal total gastrectomy, the number of positive lymph nodes, cases in tumor TNM stage Ⅰ, Ⅱ, Ⅲ, Ⅳ were (65±10)years, (5.1±2.4)cm, 102, 68, 28, 17(range, 12?22), 20, 57, 117, 4 for patients with Siewert Ⅱ AEG, versus (62±12)years, (6.3±3.2)cm, 28, 104, 69,18(range, 14?27), 16, 41, 134, 10 for patients with Siewert Ⅲ AEG, showing significant differ-ences betweeen them ( t=2.83, ?3.82, χ2=66.97, U=17 407.05, 17 532.00, P<0.05). (2) Follow-up and survival. All 399 patients were followed up for 34(range, 2?160)months. The 5-year overall survival rate was 29.3% for patients with Siewert Ⅱ AEG, versus 37.0% for patients with Siewert Ⅲ AEG, showing no significant difference betweeen them ( χ2=1.46, P>0.05). The median survival time and 5-year overall survival rate were 29.0 months [95% confidence interval ( CI) as 23.4?34.6 months] and 22.9% for patients undergoing transthoracic radical AEG surgery, 43.0 months(95% CI as 33.9?52.1 months) and 34.7% for patients undergoing transabdominal proximal gastrectomy, 54.0 months (95% CI as 37.6?70.4 months)and 44.3% for patients undergoing transabdominal total gastrectomy, showing a significant difference in the survival among the 3 groups ( χ2=13.81, P<0.05). Of the 198 Siewert Ⅱ AEG patients, the 5-year overall survival rate was 24.6% for the 96 patients undergoing transabdominal surgery, versus 35.4% for the 102 patients undergoing transthoracic surgery, showing no significant difference in the survival between them ( χ2=3.10, P>0.05). Of the 201 Siewert Ⅲ AEG patients, the 5-year overall survival rate was 40.0% for the 173 patients undergoing transabdominal surgery, versus 16.1% for the 28 patients undergoing transthoracic surgery, showing a significant difference between them ( χ2=11.32, P<0.05). (3) Prognostic factors analysis. Results of univariate analysis showed that surgical method, pathological N staging, patholgical M staging were related factors for prognosis of Siewert Ⅱ and Ⅲ AEG ( hazard ratio=0.68, 1.25, 2.18, 95% CI as 0.54?0.86, 1.15?1.36, 1.28?3.73, P<0.05). Results of multivariate analysis showed that transthoracic approach, pathological stage N2?N3 and pathological stage M1 were independent risk factors for prognosis of Siewert Ⅱ and Ⅲ AEG ( hazard ratio=0.64, 1.25, 2.18, 95% CI as 0.51?0.80, 1.16?1.35, 1.28?3.70, P<0.05). Conclusions:Compared with Siewert Ⅲ AEG, Siewert Ⅱ AEG has a smaller tumor diameter, less positive lymph nodes, poorer prognosis. Transthoracic approach is preffered for the Siewert Ⅱ AEG. Transthoracic approach, pathological stage N2?N3 and pathological stage M1 are independent risk factors for prognosis of Siewert Ⅱ and Ⅲ AEG.

Abordaje anterior de la cadera: historia y beneficios / Anterior Approach to the Hip: History and Benefits

Es propósito de este artículo revisar la historia del abordaje anterior de la articulación de la cadera, su vía intermuscular de acceso y los principales beneficios que posee. Popularizado por Smith-Petersen en 1917, el abordaje anterior de la cadera debe su primera referencia escrita a Carl Hueter. Todos los abordajes de la cadera han demostrado ser seguros y eficaces, con ventajas y desventajas. Se requieren estudios a largo plazo de un mayor número de pacientes para demostrar un beneficio de costo y una mayor calidad en la atención médica(AU)

Hip replacement is one of the most successful surgical treatments in orthopedic surgery. There is currently greater interest in the anterior approach to hip arthroplasties determined by the belief that being intramuscular it can lead to less pain, faster recovery, better hip stability and comparatively less risk of dislocation after surgery. The purpose of this article is to review the history of the anterior approach to the hip joint, its intramuscular access route and its main benefits. Popularized by Smith-Petersen in 1917, the anterior approach to the hip owes its first written reference to Carl Hueter. All hip approaches have been shown to be safe and effective, with advantages and disadvantages. Long-term studies of larger numbers of patients are required to demonstrate cost benefit and higher quality of medical care(AU)

Treatment strategies for posterior column injury in acetabular both-column fracture / 中华创伤骨科杂志

Acetabular both-column fractures, the most complex type in acetabular fractures, are usually caused by high-energy violence, accounting for 20% of all the acetabular fractures. Most of them need surgical treatment. Because fracture fragments in the posterior column are various, controversy exists in the treatment of the posterior column. This article summarizes the modes of exposure and internal fixation, like anterior approach, posterior approach, screwing and plating, for the posterior column injury in the acetabular both-column fractures, hoping to help proper clinical choice of the modes.

Analysis on clinical effects of two surgical approaches in percutaneous spinal endoscopy for LS disc herniation / 中国骨伤

OBJECTIVE@#To analyze the clinical effects, complications and operational key points of the percutaneous endoscopic transforaminal discectomy (PETD) and percutaneous endoscopic interlaminar discectomy (PEID) in treating LS disc herniation.@*METHODS@#The clinical data of 158 patients with L5S1 disc herniation treated from July 2015 to March 2018 were restospectively analyzed. According to different surgical approaches, the patients were divided into PETD group or PEID group, 79 cases in each group. In PETD group, there were 41 males and 38 females, with an average age of (41.38±6.25) years and course of disease of (10.06±3.14) months. In PEID group, there were 43 males and 36 females, with an average age of (41.18±5.78) years and course of disease of (9.99±2.83) months. The operation length, intraoperative blood loss, intraoperative fluoroscopy times, days of hospital stay, and complications were recorded between two groups. Visual analogue score (VAS), Japanese Orthopedic Association(JOA) score, Oswestry Disability Index(ODI), modified Macnab criteria were used to assessed clinical effects after operation.@*RESULTS@#All patients completed surgery and were followed up for more than 1 year. (1) There were no significant differences in the intraoperative blood loss or hospitalization length between two groups(>0.05). The operation length and intraoperative fluoroscopy times in PETD group were significantly higher than in PEID group (0.05). (3)The excellence rate was 89.87% (71 / 79) in PETD group and 87.34% (69 / 79) in PEID group at the latest follow-up, with no statistical significance(>0.05). (4)Complications occurred in 2 cases in PETD group and in 3 cases in PEID group, with no significant differences between two groups.@*CONCLUSION@#The short term efficacy of the PETD is equal to that of the PEID for the LS disc herniation, but PEID is superior in the operation length, the access of stereotaxic puncture and intraoperative fluoroscopy times. The complications can be effectively reduced by following the indications, mastering the endoscopic technique, operating carefully and being familiar with the key points of common complications.

Abordaje supraclavicular para el traumatismo vascular subclavio / Supraclavicular approach for subclavian vascular injuries

Introducción: la lesión traumática de los vasos subclavios no es frecuente. La causa fundamental está centrada en las heridas por armas de fuego y por objetos perforo-cortantes. La hemorragia o un hematoma en la zona de la base del cuello o tórax superior nos hacen pensar en esta lesión. El tratamiento depende principalmente de la estabilidad hemodinámica del paciente y los recursos disponibles. Este puede ser quirúrgico convencional o reparación endovascular. Objetivos: exponer los beneficios del abordaje supraclavicular para el tratamiento quirúrgico urgente de la lesión de vasos subclavios. Métodos: se realizó un estudio observacional, retro y prospectivo para recolectar la información de los pacientes atendidos por lesión traumática de vasos subclavios en nuestro centro, desde noviembre de 2011 hasta octubre de 2015. Resultados: de los pacientes intervenidos, 10 fueron hombres y una mujer. Todas las lesiones fueron por objetos perforo-cortantes. El tipo de lesión más frecuente fue la laceración de vena subclavia (63,6 por ciento). La vía de abordaje más utilizada fue la cervicotomía en tercio inferior con prolongación supraclavicular con clavicectomía y osteosíntesis ulterior. Hubo 3 fallecidos (27,3 por ciento). Conclusiones: la herida de vasos subclavios sucede más frecuente por objetos perforo-cortantes y tiene una alta mortalidad, la vía supraclavicular resultó la de mejor exposición para repararla. La prontitud del tratamiento fue la variable que más influyó en la morbilidad y mortalidad de esta afección(AU)

Introduction: traumatic injury of the subclavian vessels is rare. The main cause is focused on ballistic trauma and pierced-sharp objects. Bleeding or hematoma in the areas of the neck base or the upper chest lead us to think of this injury. Treatment depends mainly on the patient's hemodynamic stability and available resources. This may be conventional surgical or endovascular repair. Objectives: expose the benefits of supraclavicular approach to the urgent surgical treatment of the subclavian vessel lesions. Methods: a prospective and retro observational study was performed to gather information from patients treated for traumatic lesion of subclavian vessels in our hospital from November 2011 to October 2015. Results: out of the operated patients, 10 were men and one was woman. All lesions were drilled-sharp objects. The most common type of injury was the subclavian vein laceration (63.6 percent). The most commonly used approach was the cervicotomy in the lower third with supraclavicular clavicotomy clavicectomía and further extension with osteosynthesis. There were 3 deaths (27.3 percent). Conclusions: subclavian vessel wounds most frequently occur due to perforating-cutting objects and has a high mortality. The supraclavicular approach was the best access for repair. The promptness of treatment was the variable that most influenced the morbidity and mortality of this condition(AU)

Morphometric evaluation of the uncinate process and its importance in surgical approaches to the cervical spine: a cadaveric study

<p><b>INTRODUCTION</b>The uncinate process (UP) has an important role because of its relationship with the vertebral artery and spinal roots. Degenerative diseases cause osteophyte formation on the UP, leading to radiculopathy, myelopathy and vertebral vascular insufficiency, which may require surgical management. This study aimed to evaluate the morphometry of this region to shed light on the anatomy of the UP.</p><p><b>METHODS</b>Morphometric data was obtained from 13 male formaldehyde-fixed cadavers. Direct measurements were obtained using a metal caliper. Computed tomography (CT) morphometry was performed with the cadavers in the supine position.</p><p><b>RESULTS</b>Direct cadaveric measurements showed that the height of the UP increased from C3 (5.8 ± 1.0 mm) to C7 (6.6 ± 0.5 mm). On CT, the corresponding measurements were 5.9 ± 1.2 mm at C3 and 6.9 ± 0.6 mm at C7. The distance between the left and right apex of the UP from C3 to C7 also increased on both direct cadaveric and CT measurements (C3: 20.8 ± 1.0 mm and C7: 28.1 ± 2.4 mm vs. C3: 23.7 ± 3.4 mm and C7: 29.0 ± 3.0 mm, respectively). On CT, the distance between the UP and superior articular process at the C3 to C7 levels were 9.8 ± 1.7 mm, 7.9 ± 1.8 mm, 7.9 ± 1.6 mm, 7.8 ± 1.3 mm and 8.2 ± 1.7 mm, respectively.</p><p><b>CONCLUSION</b>Direct cadaveric and CT measurements of the UP are useful for preoperative evaluation of the cervical spine and may lead to better surgical outcomes.</p>

Treatment options and efficacy analysis of teardrop fracture of the axis / 中华创伤杂志

Objective To determine the treatment options for teardrop fracture of the axis and discuss the treatment efficacy.Methods Nineteen patients with teardrop fracture of the axis treated from March 2003 to June 2013 were retrospectively reviewed.Teardrop fracture of the axis accounted for 3.9％ of the cervical injuries and 11.4％ of the axis fractures over the same period.There were 15 males and 4 females,at age range of 21-56 years (mean,37.8 years).Injury was caused by traffic accidents in 12 patients,falls in 6,and hit from heavy objects in 1.Cervical imaging examinations (X-ray,CT and MRI) were performed on admission.Thirteen patients were immobilized for 3 to 6 months with the Halovest device,and six patients underwent anterior cervical surgery.No patients had neurologic deficit [American Spinal Injury Association (ASIA) grade E].Visual analogue scale (VAS),implant failure and bone fusion were recorded after operation.Results All patients were followed up for 12-18 months (mean,15.6 months).At the final follow-up,no implant loosening or breakage happened and 18 patients achieved bone union.Neck mobility returned to normal,which showed VAS improved from (7.5 ± 1.2) points to (3.1 ± 1.5) points.ASIA grade E remained in 18 patients,and one patient were progressed to grade D.Conclusions Teardrop fracture of the axis is rare cervical injury,and can be treated conservatively in most cases.However,surgery is often necessary when imaging findings suggest the existence of instability.

Cavernomas de tronco encefálico: presentación de 8 casos operados, análisis y revisión del estado del arte / Brainstem cavernous malformations: a series of 8 surgicalcases, analysis and state of the art review

Introducción: Las lesiones del tronco cerebral son uno de los mayores desafíos neuroquirúrgicos. Los angiomas cavernosos de esta localización son lesiones de comportamiento agresivo, con alta morbi-mortalidad asociada, donde el neurocirujano tiene la posibilidad de curar al paciente pero con un nivel de riesgo que hacen que la oportunidad de la cirugía se mantenga en debate. Material y Método: Análisis retrospectivo de 8 casos de cavernomas de tronco operados entre los años 2009-2013 con sus características clínicas, quirúrgicas y de seguimiento. Se realiza además una revisión reflexiva sobre la evolución del manejo de estas lesiones y del estado del arte a nivel en el concierto internacional. Resultados: Los 8 casos presentaron evoluciones inmediatas y mediatas favorables tras la cirugía. No hubo mortalidad ni empeoramiento del status neurológico en relación al estado preoperatorio en ninguno de los 8 casos. Tres de los pacientes de la serie fueron operados tras caer en una condición clínica crítica y son los que registran los mayores déficits durante el seguimiento. El análisis de la evolución del manejo de este tipo de lesiones a nivel mundial revela una tendencia hacia el manejo quirúrgico precoz en lesiones sintomáticas. Conclusiones: Los resultados de esta serie así como la evolución del estado del arte permiten concluir que en pacientes sintomáticos una cirugía precoz ofrece en general mejores expectativas que intervenciones tardías para lesiones relativamente superficiales.

Introduction: Brainstem lesions are a major neurosurgical challenge. Cavernous angiomas of this location are lesions of aggressive behavior, with high morbidity and mortality associated, where the neurosurgeon has the possibility to cure the patient but with a level of risk that makes that the surgery timing remains under debate. Material and Methods: A retrospective analysis of 8 brainstem cavernomas cases operated in the period 2009-2013 is presented whit its clinical, surgical and follow-up characteristics. A thoughtful review of the evolution of the management of these lesions and the state of art in the international level is also carried out. Results: All 8 patients presented immediate and mediate favorable changes after surgery. There was no mortality or worsening of the neurological condition in relation to the preoperative status in any of the 8 cases. 3 patients in this series underwent surgery after falling in a critical condition and are those who have the highest deficit in the follow-up. The analysis of the evolution of the worldwide management of these injuries reveals a trend towards early surgical management in symptomatic lesions. Conclusions: The results of this series as well as the evolution of the state of the art let us conclude that in symptomatic patients an early surgery offers overall better expectations than later interventions in relatively superficial lesions.

Paraspinal approach versus conventional approach in pedicle screw fixation of thoracolumbar fractures / 中华创伤杂志

Objective To estimate the effect of pedicle screw fixation of thoracolumbar fractures via paraspinal approach and compare it with the conventional posterior midline approach.Methods Forty-two cases of thoracolumbar monosegmental fractures subjected to single posterior pedicle screw fixation and reduction from December 2008 to May 2010 were included in the study.Among the patients,19 cases were operated through paraspinal muscular-sparing approach (paraspinal approach group) and 23 cases through posterior midline surgical approach (conventional approach group).Surgical incision length,operation time,intraoperative blood loss,postoperative drainage volume,postoperative hospital stay,pre-and post-operative VAS and other perioperative indices as well as fracture reduction outcome were compared between the two groups.Oswestry disability index (ODI) was assessed after operation.Results There were no statistical differences between the two groups in aspects of surgical incision length,operation time,postoperative hospital stay,height restoration of fractured vertebra (P ＞ 0.05),but intraoperative blood loss (148.5 ± 26.5) ml,postoperative draining loss (72.9 ± 17.3) ml,postoperative VAS (1.1 ± 0.3) points and ODI (13.4 ± 2.7) points in paraspinal approach group showed statistical differences from those in conventional approach group (P ＜ 0.05).Conclusion Paraspinal muscle-sparing approach is characterized by minor trauma,less bleeding,slight pain and quick recovery as compared with conventional posterior midline approach and hence may be the preferred choice for the treatment of thoracolumbar fracture without spinal canal decompression.

Meningioma ventricular presentación infrecuente y revisión de la literatura / Infrequent intraventricular meningioma and review of the literature

Fundamento: Los meningiomas son tumores originados de las cubiertas aracnoideas. La localización intraventricular es rara especialmente los originados en el trígono ventricular derecho. Objetivo: Reportar un caso de localización atípica de un meningioma intracraneal. Presentación de caso: Paciente femenina de 68 años con historia de crisis convulsivas focales y cefalea de un mes de evolución. Las imágenes de Resonancia Nuclear Magnética convencionales, con secuencias en T1 y T2 axial y sagital, muestran una lesión localizada en el trígono ventricular derecho. Se realizó abordaje quirúrgico directo y excéresis total. El estudio anatomopatológico demostró un Meningioma fibroblástico. Discusión: Los meningiomas intraventriculares a nivel de trígono son infrecuentes y sólo se reportan series de pocos pacientes en la literatura. El abordaje y excéresis quirúrgica es el método de tratamiento de elección. Conclusiones: El abordaje y excéresis de meningiomas intraventriculares puede ser llevado a cabo exitosamente y en ausencia de complicaciones importantes.

Fundaments: Intraventricular meningiomas are rare often histologically benign tumors, especially those arisingfrom the right ventricular trigonal region. Objective: Report an unusual growth of intracranial meningioma. Case report: Authors present a clinical case of a 68 years old female with focal crisis and cephalea. Magnetic Resonance Imaging showed globular small hypo intense mass located in the right trigone. Surgical approach consisted in parietal craniotomy followed by dural opening and resection of the Intraventricular tumor. Post operatory evolution was adequate. Histological diagnosis was fibroblastic meningioma. Discussion: Meningiomas of the right lateral ventricule are rare and not widely reported. Surgical treatment is often successfully performed. Conclusion: Meningiomas of the lateral ventricles can be successfully diagnosed and surgically treated.
