ABSTRACT
Las fracturas con hundimiento de cráneo sin una explicación clara sobre su origen orientan al traumatismo con un objeto romo y a la sospecha de maltrato infantil. En el caso de los bebés recién nacidos, su corta edad es un factor de vulnerabilidad y obliga a una exhaustiva evaluación. Ante la sospecha de maltrato infantil, resulta importante evaluar los diagnósticos diferenciales para realizar la intervención más adecuada posible. Es necesario evitar tanto intervenciones excesivas como omitir la intervención que sea necesaria. Las fracturas craneales deprimidas congénitas, descritas como "fracturas pingpong", son raras (0,3 a 2/10 000 partos). Pueden aparecer sin antecedentes traumáticos o en partos instrumentalizados. Se describe en este artículo el caso de un recién nacido con una fractura ping-pong como ejemplo de una fractura no intencional.
Depressed skull fractures without a clear explanation as to their origin point to trauma with a blunt object and suspected child abuse. In the case of newborn infants, their young age is a vulnerability factor and requires an exhaustive assessment. When child abuse is suspected, an assessment of the differential diagnoses is required to make the most appropriate intervention possible. Both an excessive intervention and an omission of a necessary intervention should be avoided. Congenital depressed skull fractures, described as "ping-pong fractures", are rare (0.3 to 2/10 000 births). They may appear without any trauma history or in instrumentalized childbirth. Here we describe the case of a newborn infant with a ping-pong fracture as an example of an accidental fracture.

Introducción. La perforación del recto por trauma cerrado es poco frecuente y se asocia a fracturas pélvicas. En pacientes con perforaciones de recto no traumáticas se ha reportado fascitis necrosante en miembros inferiores, en la mayoría de los casos asociada a alta mortalidad. Caso clínico. Hombre de 36 años con trauma cerrado abdomino-pélvico y perforación de recto inferior, quien recibió manejo quirúrgico mediante derivación intestinal y fijación pélvica. Evolucionó con hematoma escrotal sobreinfectado, inestabilidad hemodinámica, signos de fascitis necrosante y choque séptico 4 días posterior a su ingreso. Resultados. Se tomó muestra para cultivo del hematoma escrotal que reportó E. coli. La patología del desbridamiento escrotal informó necrosis de coagulación en toda la muestra. Conclusión. El tacto rectal debe realizarse siempre ante la presencia de enfisema subcutáneo al examen físico o en la tomografía, para un diagnóstico temprano y manejo quirúrgico multidisciplinario oportuno, según el caso. La presencia de enfisema subcutáneo debe aumentar la sospecha de perforación de recto. Hay pocos reportes de fascitis secundaria a perforación de recto por trauma cerrado, por lo que no se conoce con precisión la mortalidad asociada.
Introduction. Rectal perforation due to blunt trauma is rare and associated with pelvic fractures. Signs of necrotizing fasciitis in lower limbs have been reported in non-traumatic rectal perforations, in most cases associated with high mortality. Case report. A 36-year-old man presents blunt abdomino-pelvic trauma and perforation of the lower rectum. Surgical management by intestinal diversion and pelvic fixation is performed. 4 days after admission, evolves with over-infected scrotal hematoma, hemodynamic instability, signs of necrotizing fasciitis and septic shock. Results. A sample for culture was taken from a scrotal hematoma that reported E. coli. Pathology of scrotal debridement reported coagulation necrosis in the entire specimen. Discussion. Digital rectal examination should always be performed in the presence of subcutaneous emphysema on physical examination or CT scan for early and multidisciplinary diagnosis and surgical management as appropriate. Conclusion. The presence of subcutaneous emphysema should raise the suspicion of rectal perforation. There are few reports of rectal perforation due to blunt trauma and fasciitis, so the associated mortality is not precisely known.

OBJECTIVE To provide reference for improving the level of hospital pharmaceutical management for operating room drugs. METHODS The operating room pharmacy of our hospital utilized the concept and means of the Internet of Things （IoT） to build an intelligent IoT system for operating room drugs （hereinafter referred to as the “IoT system”）， and optimized and improved it. The quality of drug management in the operating room of our hospital during the initial phase of the IoT system （Q1 2022） and after optimization and improvement （Q1 2023） were compared by setting indicators from four aspects： quality， efficiency， cost， and satisfaction. RESULTS After more than a year of optimization and improvement， our hospital has built a traceable IoT system for the entire drug process that integrated surgical anesthesia systems and hospital information systems， with the direction of drug circulation in the operating room as the axis， using intelligent drug vehicles as the hardware foundation， and anesthesia doctor’s order information system as the software medium. After the optimization and improvement of the IoT system， the standardized score of anesthesia orders in the operating room increased from （68.5±3.5） points in the initial period to （97.0± 2.7） points； the consistency rate between accounts and materials increased from （82.40±8.85）% to （96.50±4.80）%； the time of taking medicine was shortened from （40±8） min to （12±3） min； the frequency of drug withdrawal was reduced from （36.0± 6.5） times/day to （15.5±3.0） times/day； the cost of loss drugs was decreased from （1 292.61±305.90） yuan to （594.24±195.05） yuan； the satisfaction was increased from （80.5±6.5） points to （96.0±3.0） points. All indicators were significantly improved with statistically significant differences （P＜0.05）. CONCLUSIONS The intelligent IoT system constructed by our hospital effectively ensures the accessibility， timeliness， and safety of intraoperative medication， which is conducive to improving the quality of drug management in the operating room.
ABSTRACT
ABSTRACT The aim of this study was to assess the efficacy and safety of hybrid closed-loop (HCL) systems for insulin delivery in children and adolescents with type 1 diabetes (T1D). We searched Embase, PubMed, and Cochrane Library for randomized controlled trials (RCTs) published until March 2023 comparing the HCL therapy with control therapies for children and adolescents with T1D. We computed weighted mean differences (WMDs) for continuous outcomes and risk ratios (RRs) with 95% confidence intervals (CIs) for binary endpoints. Four RCTs and 501 patients were included, of whom 323 were randomized to HCL therapy. Compared with control therapies, HCL significantly improved the period during which glucose level was 70-180 mg/dL (WMD 10.89%, 95% CI 8.22-13.56%) and the number of participants with glycated hemoglobin (HbA1c) level < 7% (RR 2.61, 95% CI 1.29-5.28). Also, HCL significantly reduced the time during which glucose level was > 180 mg/dL (WMD -10.46%, 95% CI -13.99 to -6.93%) and the mean levels of glucose (WMD -16.67 mg/dL, 95% CI -22.25 to -11.09 mg/dL) and HbA1c (WMD -0.50%, 95% CI -0.68 to -0.31). There were no significant differences between therapies regarding time during which glucose level was < 70 mg/dL or <54 mg/dL or number of episodes of ketoacidosis, hyperglycemia, and hypoglycemia. In this meta-analysis, HCL compared with control therapies was associated with improved time in range and HbA1c control in children and adolescents with T1D and a similar profile of side effects. These findings support the efficacy of HCL in the treatment of T1D in this population.
ABSTRACT
BACKGROUND:Stable intertrochanteric fractures can be treated by closed reduction and internal fixation,but there is no absolute advantage for unstable intertrochanteric fractures with osteoporosis. OBJECTIVE:To investigate the efficacy of arthroplasty in the treatment of unstable intertrochanteric fractures in the elderly with osteoporosis by comparing the indexes related to closed reduction internal fixation and arthroplasty. METHODS:Clinical data of 102 elderly patients with unstable intertrochanteric fractures of the femur treated in Affiliated Hospital of Qingdao University from January 2017 to January 2020 were retrospectively analyzed.Patients were divided into two groups according to the surgical method.In the Gamma3 group,62 cases received Gamma3 internal fixation system.In the joint replacement group,40 cases received an artificial femoral head replacement or total hip replacement.Surgical information,hospitalization,hip function,and postoperative complications were compared between the two groups. RESULTS AND CONCLUSION:(1)There were statistical differences between the Gamma3 group and the joint replacement group in weight-bearing time(P＜0.001),hospital stay(P＜0.05),intraoperative bleeding(P＜0.001),and length of surgery(P＜0.001).The mean weight-bearing time and hospital stay were shorter in the joint replacement group than in the Gamma3 group.Intraoperative bleeding and duration of surgery were better in the Gamma3 group than in the joint replacement group.(2)There was no significant difference in Harris hip score,subitem centesimal hip score,and postoperative complications 12 months after surgery in both groups(P=0.526,0.788,0.228).(3)It is indicated that arthroplasty has achieved better outcomes in the treatment of elderly unstable intertrochanteric fractures combined with osteoporosis,enabling early weight bearing and functional exercise.Careful selection of the appropriate patient and prosthesis type for arthroplasty will result in greater patient benefit.

ABSTRACT
【Objective】 To analyze the detection characteristics of a novel serum marker, hepatitis B core-associated antigen (HBcrAg), in the HBsAg-/HBV DNA+ blood donors in Wuxi. 【Methods】 A total of 37 previous HBsAg-/HBV DNA+ blood donors were followed up by telephone and their serum was obtained, and the serum of 22 HBsAg-/HBV DNA+ blood donors was detected by electrochemiluminescence and real-time PCR nucleic acid screening as the OBI group for HBcrAg enzyme-linked immunosorbent assay(ELISA). The serum of 20 healthy blood donors who underwent dual ELISA and one nucleic acid testing(NAT) was selected as the healthy control group, and the serum of 20 patients with chronic hepatitis B who were clinically diagnosed by Wuxi Fifth People's Hospital was selected as the experimental CHB group, and HBcrAg ELISA was detected respectively. The correlation analysis between HBcrAg and HBeAb, HBcAb, ALT and HBV DNA in the OBI group was performed. 【Results】 Thirty-seven blood samples were detected by chemiluminescence for HBsAg and NAT, and 22 HBsAg-/HBV DNA+ samples were detected in the OBI group, with a detection rate of 59.46%. The serum HBcrAg expression content (ng/mL) between the OBI group, the healthy control group and the CHB group were (0.92±0.13), (0.47±0.09) and (1.14±0.23), respectively, and the differences were statistically significant (P0.05). 【Conclusion】 The expression of HBcrAg in the OBI group and CHB group was higher than that in the healthy control group, and the serum HBcrAg was not correlated with HBeAb, HBcAb, ALT and HBV DNA to a certain extent. HBcrAg has a good application prospect in screening HBsAg-/HBV DNA+ blood donors.

ABSTRACT
Objective To explore the clinical efficacy of azithromycin sequential therapy(AST)combined with infantile massage(IM)in children with chronic cough after mycoplasma pneumoniae infection(CCAMP)phlegm-heat closed lung syndrome(PHCLS),and provide a new scheme for the clinical diagnosis and treatment of CCAMP.Methods The study retrospectively collected children with CCAMP-PHCLS diagnosed in the Second Affiliated Hospital of Guangzhou University of Chinese Medicine from March 2022 to March 2023.According to the treatment regimes,the children were divided into AST group and AST+IM group.The differences in cough symptoms integral and inflammatory factors(IL-6,PCT and CRP)between the two groups of CCAMP-PHCLS children were observed and compared.In addition,the total time to disappearance of clinical symptoms/signs,negative conversion of serum MP antibody(MP-IgM),total treatment response rate and incidence of adverse reactions were compared between the two groups.Results A total of 98 CCAMP-PHCLS children were collected,49 in each group.There were no significant differences between the AST+IM group and AST group in daytime cough symptoms points,nighttime cough symptoms points,serum IL-6 content,serum PCT content,and serum CRP content before treatment(P>0.05).After treatment,the daytime cough symptoms,serum IL-6,serum PCT and serum CRP in both groups significantly decreased compared to before treatment,and the above indicators in the AST+IM group were lower than those in the AST group(P<0.05).In terms of clinical characteristics,CCAMP-PHCLS children lost cough,fever and lung rales in the AST+IM group were shorter than the AST group(P<0.05),and the MP-IgM conversion rate was significantly higher than the AST group(P<0.05).In addition,in terms of clinical efficacy and safety,the total response rate of CCAMP-PHCLS in the AST+IM group was significantly higher than that in the AST group(P<0.05),while the incidence of adverse reactions of CCAMP-PHCLS in the AST+IM group was significantly lower than that in the AST group(P<0.05).Conclusion IM combined with AST has significant efficacy and high safety in children with CCAMP.The potential possible mechanism is that IM mediate production of inflammatory factors,and improves airway inflammation,thus alleviating clinical symptoms and signs.
ABSTRACT
Objective:To construct a double-closed-loop management model for medical equipment and explore its application value in hemodialysis machine maintenance and fault management.Methods:Based on the closed-loop management of clinical operation of medical equipment and the closed-loop management of technical support,a dual closed-loop management model of equipment was constructed.65 hemodialysis machines in clinical use in Huashan Hospital Fudan University from January 2021 to January 2023 were selected and divided into a conventional mode and double-closed-loop mode according to different management modes.The conventional mode adopted conventional equipment management methods,and the double-closed-loop mode adopted a double-closed-loop management model.The cost-effectiveness,social benefit,failure occurrence,effective management quality matters,disinfection status,average patient waiting time and satisfaction were compared between the two groups.Results:The hemodialysis machine operating profit growth rate,diagnosis and treatment cost growth rate,service life index,scientific research service growth rate,diagnosis and treatment service growth rate,startup rate and operation rate of the double-closed-loop mode were(3.95±1.04)%,(3.80±0.58)%,(1.58±0.31)%,(4.30±0.95)%,(7.91±1.58)%,(96.58±2.76)%and(89.90±5.58)%,which were higher than those of the Conventional mode,the difference was statistically significant(t=5.418,10.070,7.490,17.570,11.820,8.849,6.840,P<0.05).The technical support expenses growth rate,bacterial colony count,bacterial endotoxin content and average patient waiting time of patients in the Double-closed-loop mode were(2.60±0.33)%,(0.370±0.008)cfu/ml,(0.0063±0.0011)EU/ml and(0.76±0.13)h,which were less than those of the conventional mode,the difference was statistically significant(t=23.040,82.985,14.482,19.530,P<0.05).The incidence rate of hemodialysis machine failure in the double-closed-loop mode was 9.23%(6/65),which was lower than that in the conventional mode,the difference was statistically significant(x2=6.392,P<0.05);among the 120 items of management data collected,quality control testing,maintenance and repair,clinical operation,information data,and scrap processing effectiveness rates were 95.83%(115/120),89.17%(107/120),96.67%(116/120),95.00%(114/120),and 97.50%(117/120),respectively,which were higher than those of the conventional mode,the difference was statistically significant(x2=15.238,16.596,9.808,15.585,16.119,P<0.05).Conclusion:The application of closed-loop management model to hemodialysis machine maintenance and fault management can effectively improve equipment cost-effectiveness,social benefits,management quality and patient satisfaction,and reduce the incidence of faults.
ABSTRACT
Objective:To explore the optimal index of rotational displacement of femoral neck fractures by modeling the axial rotational displacement of femoral neck fractures after reduction and based on X-ray projections.Methods:Six dry human femur specimens, comprising 2 males and 4 females, were utilized in the study. Design and manufacture a proximal femur ortholateral and oblique X-ray casting jigs and mounts. The femoral neck fracture was modeled on the femoral specimen, with Pauwells 30°, 50°, and 70° models (2 each) made according to Pauwells typing. The fractures were manually repositioned with residual anterior 20°, 40° and 60° axial rotational displacements. Each fracture model was projected at different angles (pedicled 40°, pedicled 20°, vertical 0°, cephalad 20°, and cephalad 40°), and the trabecular angle and Garden's alignment index of the model were measured to observe the imaging characteristics of the fracture line on the medial oblique and lateral oblique radiographs.Results:In the presence of a 20° and 40° anterior rotational displacement following reduction of a femoral neck fracture, the trabecular angle in the rotationally displaced group was not significantly different from that of the anatomically repositioned group in various projection positions. However, when a residual rotational displacement of 60° was present, the trabeculae appeared blurred at most projection angles in the Pauwells 30° and 50° models, failing to measure trabecular angles. In the Pauwells 70° fracture model, the trabecular angle in the rotational displacement group was significantly different from that in the anatomical reduction group. In anteroposterior radiographs, when the anterior rotation displacement was 60° in the Pauwells 70° group, Garden's contralateral index showed an unsatisfactory restoration (150°, 142°), whereas all rotationally displaced models in the Pauwells 30° and Pauwells 50° groups had a Garden's contralateral index of >155°, which achieved an acceptable restoration. In lateral radiographs, all rotational displacement models with Garden's alignment index>180° failed to achieve acceptable repositioning, and the larger the Pauwells angle the greater the Garden's alignment index at the same rotational displacement. In the internal oblique position with a bias towards the foot side, the image showed partial overlap between the femoral head and the shaft, making it difficult to assess the quality of the reduction. Conversely, when projected cephalad, the femoral neck appeared longer, particularly at a projection angle of 40° cephalad, allowing for clear observation of the fracture line and the anatomy of the proximal femur. The trabeculae were not well visualized in the external oblique position.Conclusion:There are limitations in applying the trabecular angle to assess the axial rotational displacement of the femoral head after reduction of femoral neck fractures. The Pauwells 70° with residual rotational anterior displacement of 60° was the only way to detect axial rotational displacement of the femoral head on anteroposterior radiographs Garden's alignment index. For the determination of axial rotational displacement of the femoral head, the Garden's alignment index on lateral radiographs provides higher reliability.
ABSTRACT
Abstract Background: This randomized and controlled prospective study tested the hypothesis that closed-loop Target-Controlled Infusion (TCI) of propofol would be associated with better system performance when compared with open-loop controlled delivery of propofol. Methods: Patients scheduled for elective breast surgery were randomly assigned to two groups: a closed-loop group, in which propofol infusion was performed by a closed-loop TCI system that used the Bispectral Index (BIS) as a feedback parameter to titrate the rate of propofol infusion, and an open-loop group, in which propofol infusion was performed manually and guided by the bispectral index. Results: A total of 156 patients were recruited for this study (closed-loop group n = 79; open-loop group n = 77). The Global Score (GS) of the closed-loop group was lower than that of the open-loop group (34.3 and 42.2) (p = 0.044). The proportions of time with a BIS value between 40 and 60 were almost identical in the closed-loop group and the open-loop group (68.7 ± 10.6% and 66.7 ± 13.3%) (p = 0.318). The individuals in the closed-loop group consumed more propofol compared with those in the open-loop group (7.20 ± 1.65 mg.kg−1.h−1 vs. 6.03 ± 1.31 mg.kg−1.h−1, p < 0.001). No intraoperative recall, somatic events or adverse events occurred. No significant difference in heart rate was observed between the two groups (p = 0.169). Conclusion: The closed-loop protocol was associated with lower BIS variability and lower out-of-range BIS values, at the cost of a greater consumption of propofol when compared to the open loop group. Register number:ChiCTR-INR-17010399.
ABSTRACT
Introducción: El Campamento Tortuguero de Cedeño ha sido el sitio menos investigado del Golfo de Fonseca, donde se protege a la tortuga golfina en Honduras desde 1975. Objetivo: Evaluar la anidación de la tortuga Golfina (Lepidochelys olivacea) durante la temporada de veda entre el 2011 y 2021 en Campamento Tortuguero Cedeño, Choluteca, Honduras. Métodos: Entre 2011 a 2021, se llevó a cabo el monitoreo diario de las actividades de anidación durante la veda del 1 al 25 de septiembre. Los patrullajes se realizaron entre las 6:00-18:00 h, y las 18:00-5:00 h. Se registró el número total de tortugas que anidaban y se recogieron sus huevos, que se transportaron al criadero, donde se tabularon los resultados de las puestas y las crías. Resultados: Se registró un total 1 065 tortugas de L. olivacea, 95 051 huevos recolectados, 1 065 nidos marcados en tres playas que fueron reubicados en viveros artificiales y una eclosión exitosa de 62 747 neonatos. La playa Las Doradas fue el sitio con el mayor número de tortugas anidadoras, seguido de Los Delgaditos y por último Cedeño. El promedio de la frecuencia de anidación fue de 96 nidos. Del 2011 al 2021 el esfuerzo de recolección de los nidos aumentó en un 91.6 %, pasando de 84 a 161 nidos. El número de personas patrullando se asoció con la cantidad de nidos detectados en las playas. Conclusión: Los esfuerzos de monitoreo y conservación para la especie han indicado que ha habido un incremento en la anidación de L. olivacea en las tres playas, con un mayor incremento en Playa Las Doradas. Este escenario comprueba la funcionalidad de la veda en esta zona.
Introduction: The Cedeño Turtle Camp has been the least researched site in the Fonseca Gulf, where Olive Ridley Turtles in Honduras have been protected since 1975. Objective: To evaluate the nesting of Olive Ridley turtles (Lepidochelys olivacea) during the closed season from 2011 to 2021 in Campamento Tortuguero Cedeño, Choluteca, Honduras. Methods: From 2011 to 2021, daily monitoring of nesting activities was conducted during the closed season from the 1st to 25th of September. Patrols were conducted between 6:00-18:00 h, and 18:00-5:00 h. The total number of nesting turtles was recorded, and their eggs were collected and transported to the hatchery, where clutch and hatchling performance were tabulated. Results: A total of 1 065 L. olivacea turtles were recorded, 95 051 eggs collected, 1 065 nests marked on three beaches that were relocated in artificial hatcheries and a successful hatching of 62 747 hatchlings. Las Doradas beach was the site with the highest number of nesting turtles, followed by Los Delgaditos and lastly Cedeño. The average nesting frequency was 96 nests. From 2011 to 2021 the nest collection effort increased by 91.6 %, from 84 to 161 nests. The number of people patrolling was associated with the number of nests detected on the beaches. Conclusion: Monitoring and conservation efforts for L. olivacea in the Campamento Tortuguero Cedeño show a positive trend in nesting with a greater increase in Playa Las Doradas. This scenario proves the functionality of the closed season in this area.

Resumen Introducción: Las lesiones de la mano son uno de los padecimientos más frecuentemente atendidos en el Servicio de Cirugía Plástica y Reconstructiva del Hospital Central Militar, dentro de la amplia variedad de estas lesiones se encuentran las lesiones del sistema flexor. Objetivo: Estimar la incidencia, funcionalidad y tiempo de reintegración laboral en pacientes con lesiones de sistema flexor de la mano tratados en el Hospital Central Militar en el periodo del 1º de marzo del 2020 al 1º de marzo del 2022. Metodología: Estudio observacional, retrospectivo, longitudinal descriptivo en pacientes adultos con lesión de sistema flexor de la mano, en los cuales la causa de la lesión no haya condicionado un trauma complejo de la mano. Se utilizó como referencia los criterios de recuperación funcional de Strickland y Goglovac. Resultados: A pesar de que las lesiones de la zona II flexora en la literatura presentan un peor pronóstico para la recuperación de la función normal de la mano, los resultados demuestran que la mayor parte de los pacientes se encuentra en una escala funcional buena. Limitaciones del estudio: El estudio fue llevado a cabo durante el periodo comprendido por la pandemia COVID, por lo que las consultas subsecuentes con tiempos más alargados y el inicio tardío de las consultas de rehabilitación pudieron haber contribuido hacia una recuperación más deficiente de la recuperación funcional de los pacientes.
Abstract Introduction: Hand injuries are one of the conditions most frequently treated in the Plastic and Reconstructive Surgery Service of the Hospital Central Militar, within the wide variety of these injuries are injuries to the flexor system. Objective: To estimate the incidence, functionality and labor reintegration time in patients with hand flexor system injuries treated at the Hospital Central Militar in the period from March 1, 2020 to March 1, 2022. Methodology: Observational, retrospective, longitudinal, descriptive study in adult patients with injury to the flexor system of the hand, in whom the cause of the injury did not result in complex trauma to the hand. The Strickland and Goglovac functional recovery criteria were used as reference. Results: Despite the fact that flexor zone II lesions in the literature present a worse prognosis for the recovery of normal hand function, the results show that most of the patients are in a good functional scale. Limitations of the study: The study was carried out during the period covered by the COVID pandemic, so that subsequent consultations with longer times and the late start of rehabilitation consultations could have contributed to a poorer recovery of functional recovery. from the patients.
ABSTRACT
Abstract Objective The present study compares the analgesic efficacy of two techniques to perform non-surgical reduction: fracture hematoma block and radial nerve supracondylar block. Methods Forty patients with fractures of the distal third of the radius, who required reduction, were selected in a quasi-randomized clinical trial to receive one of the anesthetic techniques. All patients signed the informed consent form, except for those who did not wish to participate in the study, had neurological injury, had contraindication to the procedure in the emergency room, or with contraindication to the use of lidocaine. To measure analgesia, the numerical pain rate scale was used at four different moments: preblock, postblock, during reduction, and after reduction; then three differences were calculated: the first between before and after blocking; the second between during reduction and after blockade; and the third between before blocking and after reduction. Results The fracture hematoma and supracondylar block groups showed the following mean values, respectively: 3.90 (1-10) and 3.50 (-6-10) in difference 1; 4.35 (-5-10) and 5.00 (-3-10) in difference 2; and 4.65 (1-10) and 3.80 (-3-10) in difference 3. Conclusion Both techniques proved to be efficient for analgesia, with mild superiority of hematoma block, but without statistical significance.
Resumo Objetivo O estudo compara a eficácia analgésica de duas técnicas para realizar redução incruenta: o bloqueio de hematoma da fratura e o bloqueio supracondilar de nervo radial. Métodos Quarenta pacientes com fraturas do terço distal do rádio, que necessitassem redução, foram selecionados em um ensaio clínico quasi-randomizado, para receber uma das técnicas anestésicas. Todos os pacientes assinaram o termo de consentimento ou assentimento, com exceção daqueles que não desejassem participar do estudo, tivessem lesão neurológica, com contraindicação ao procedimento na sala de emergências, ou com contraindicação ao uso da lidocaína. Para aferir a analgesia foi utilizada a escala numérica da dor em quatro momentos distintos: pré-bloqueio, pós-bloqueio, durante a redução e após a redução; em seguida, foram calculadas três diferenças: a primeira entre antes e após o bloqueio; a segunda entre durante a redução e após o bloqueio; e a terceira entre antes do bloqueio e após a redução. Resultados Os grupos do bloqueio de hematoma de fratura e bloqueio supracondilar apresentaram respectivamente os seguintes valores médios: 3.90 (1-10) e 3.50 (-6-10) na diferença 1; 4.35 (-5-10) e 5.00 (-3-10) na diferença 2; e 4.65 (1-10) e 3.80 (-3-10) na diferença 3. Conclusão As duas técnicas se provaram eficientes para analgesia, com discreta superioridade do bloqueio de hematoma, mas sem significância estatística.

Resumen Este ensayo cuestiona las verdades matemáticas como principio explicativo del conocimiento científico médico. Se analiza, en primer término, el concepto de normalidad actual basado en una distribución de valores probabilísticos, y se destacan sus limitaciones y equívocos para captar la complejidad de la condición humana. Los sistemas cerrados (juegos de azar), origen de la teoría de las probabilidades y del binomio causalidad-azar, se comparan con los sistemas abiertos propios del proceso vital y se argumentan sus diferencias extremas. Se destaca el despropósito de depositar en el binomio causalidad-azar el significado de asociaciones entre sucesos propios de la complejidad de la vida humana en salud y enfermedad. Se confrontan las características de la causalidad mecanicista (puntual, lineal, unidireccional, homogénea y fija), que equipara al organismo con una máquina y es la única explicación científica aceptada del acontecer de la vida humana, con las de la causalidad contextual (difusa, heterogénea, jerárquica, multidireccional y cambiante), que especifica diversos órdenes causales interactuantes que dan forma a la condición humana: el histórico, el social, el político, el económico, el cultural o el biológico, que representa una mirada escrutadora y penetrante de la complejidad de los seres humanos. Se concluye la superioridad de la causalidad contextual sobre la mecanicista, que abre posibilidades explicativas de sucesos vitales que suelen arrumbarse como «efectos del azar¼. Esta aproximación integradora a la complejidad humana puede enriquecer y fortalecer el método clínico, hoy degradado y en riesgo de extinción.
Abstract This essay questions mathematical truths as an explanatory principle of the medical scientific knowledge. It analyzes, in the first place, the current concept of normality based on a distribution of probabilistic values and its limitations and mistakes to capture the complexity of the human condition are highlighted. The closed systems (gambling) origin of the theory of probabilities and the binomial causality-chance are compared with open systems typical of the complexity of the vital process, and their extreme differences are argued. The nonsense of depositing in the causality-chance binomial the meaning of associations between events typical of the complexity of human life in health and disease is highlighted. The characteristics of mechanistic causality (punctual, homogeneous, linear, unidirectional and fixed), which equates the organism with a machine and is the only accepted scientific explanation of events of human life, are confronted with those of contextual causality (diffuse, heterogeneous, hierarchical, multidirectional and changing), which specifies various interacting causal orders that shape of human condition: the historical, the social, the political, the economical, the cultural or the biological that represents a scrutinizing and penetrating look at the complexity of human beings. It concludes the superiority of contextual causality over mechanistic causality that opens up explanatory possibilities of the vital events that are usually put away as "effects of chance". This integrative approach to the human complexity can enrich and strengthen the clinical method that is now degraded and at risk of extinction.
ABSTRACT
@#Impacted teeth are a kind of complex malocclusion, and their incidence differs among different races, sexes and dental positions. The causes of impacted teeth include systemic factors and local factors, such as endocrine disorders, malnutrition, and acute and chronic infectious diseases. Local factors can cause abnormal tooth development or eruption during the process from tooth development to tooth eruption, such as damaged permanent tooth embryos caused by local inflammation or trauma, insufficient eruption space caused by premature loss of deciduous teeth, and eruption disorders caused by local lesions for example hyperplasia or odontoma. The clinical manifestation of impacted teeth is the absence of a permanent tooth in a normal position. We can use cone beam CT (CBCT) to locate the impacted teeth. Comprehensive orthodontic treatment includes surgical-assisted eruption, extraction of retained deciduous teeth or supernumerary teeth, removal of lesions such as odontomas and cysts, and expansion of the orthodontic space. When the dysfunctional local soft and hard tissues are removed during a surgical operation, the tooth still cannot sprout smoothly, and it needs to be assisted by orthodontic traction-guided eruption or extracted and autotransplantation. A clear diagnosis, evaluation of the difficulty of treatment and appropriate treatment are the keys to improving the success rate of treatment. In this paper, the epidemiology, etiology, diagnosis and corresponding treatment methods of impacted teeth will be reviewed, and the orthodontic treatment of impacted teeth will be comprehensively described to provide a reference for clinicians about the treatment of impacted teeth.
ABSTRACT
Objective:To investigate the surgical method of LC-II screws for fragility fractures of the pelvis (FFP) in the elderly and evaluate its clinical efficacy.Methods:A retrospective analysis was performed on 45 patients with FFPs operated in our department from January 2011 to January 2022. The clinical information was as follows. The FFP classification of pelvic fracture was IIIA in 26 cases and IIIB in 19 cases. Among them, 22 cases were fixed with closed reduction and modified LC-II screws (experimental group), and 23 cases were fixed with open reduction and reconstruction plates (control group). In the experimental group, there were 6 males and 16 females. The age range was 62-90 years, with an average of 73.2±9.2 years. The FFP classification of pelvic fracture was IIIA in 12 cases and IIIB in 10 cases. In the control group, there were 8 males and 15 females. The age range was 60-87 years, with an average of 72.8±6.6 years. FFP classification of pelvic fracture was IIIA in 14 cases and IIIB in 9 cases. After admission, pelvic X-ray and CT scan were performed, and the surgery was prepared. In the experimental group, after closed reduction of the posterior ring, the modified LC-II screw was inserted below the anterior inferior iliac spine (AIIS) toward the sacroiliac joint and penetrated the sacroiliac joint. For combined anterior ring fractures, the INFIX was used for anterior ring fixation. In the control group, the posterior ring was fixed with a reconstruction plate and/or sacroiliac screw after open reduction through the lateral rectus approach (LRA). The clinical efficacy was evaluated between the experimental group and the control group.Results:All 45 patients were successfully operated and followed up for 6 months to 3 years. All the pelvic fractures healed. In the experimental group of 22 cases, the time from injury to operation was 3-9 days, with an average of 5.8±1.9 days; the operation time was 25-70 min, with an average of 42.0±12.9 min. The intraoperative bleeding was 20-40 ml, with an average of 29.1±6.7 ml. According to the X-ray reduction evaluation criteria of Matta, 7 cases were excellent, 11 cases were good and 4 cases were medium, with an excellent and good rate of 81.8%. According to rehabilitation criteria of Majeed, 10 cases were excellent, 6 cases were good and 6 cases were fair, with a total excellent and good rate of 72.7%. At the last follow-up, sacroiliac joint pain was evaluated by VAS score: 0 in 10 cases, <3 in 7 cases, and 4-6 in 5 cases. No internal fixation loosening occurred. In the control group, the time from injury to operation was 5-20 days, with an average of 9.9±3.8 days; the operation time was 50-150 min, with an average of 89.1±29.5 min; the intraoperative bleeding was 220-1 000 ml, with an average of 509.2±214.3 ml. According to the X-ray reduction evaluation criteria of Matta, 16 cases were excellent, 4 cases were good and 3 cases was medium, with an excellent and good rate of 87.0%. According to rehabilitation criteria of Majeed, 12 cases were excellent, 6 cases were good and 7 cases were fair, with a total excellent and good rate of 78.3%. At the last follow-up, sacroiliac joint pain was evaluated by VAS score: 0 in 14 cases, <3 in 6 cases, and 4-6 in 3 cases. In the control group, posterior ring plate loosening was found in 2 cases and anterior ring pubic ramus plate and screw loosening was found in 4 cases, but there was no reduction loss.Conclusion:The modified LC-II screw is theoretically feasible in the treatment of FFP. Preliminary clinical results show good safety and efficacy, providing a new idea for minimally invasive treatment of FFP.
ABSTRACT
Objective:To investigate the clinical efficacy of the femoral neck system (FNS) after the reduction of the Schanz screw combined with the rod stick technique in the treatment of valgus-impacted femoral neck fracture.Methods:A retrospective analysis of clinical data from 66 patients with valgus-impacted femoral neck fractures from December 2019 to November 2021 has been performed. All patients were treated with the Femoral Neck System. Auxiliary reduction group (using the Schanz screw and rod stick technique), including 32 cases, 9 males and 23 females with an average age of 52.7±12.0 years (range, 28-77 years); 14 patients on the left side and 18 patients on the right side; body mass index 23.1±2.6 kg/m 2. Manual reduction group (using the traditional Flynn closed reduction technique), including 34 cases, 18 males and 16 females with an average age of 52.1±12.7 years (range, 26-75 years); 18 patients on the left side and 16 patients on the right side; body mass index 23.4±2.3 kg/m 2. The surgery time, intraoperative blood loss, complications, and Harris hip score at the last follow-up were collected and compared between the two groups. Preoperative and postoperative abduction angle and posterior tilt angle were measured in the anterior-posterior and lateral positions of the hip, as well as the length of the femoral neck shortening at the last follow-up. Pearson analysis was used to evaluate the correlation between preoperative and postoperative abduction angle and posterior tilt angle, the length of femoral neck shortening, and Harris hip score. Results:There were no significant differences in baseline data such as gender, age, side of injury, height, weight, and body mass index, and the surgery time and intraoperative blood loss between auxiliary reduction group and manual reduction group ( P>0.05). All 66 cases with a mean follow-up of 20.4 months (ranges 12-29 mouths). The fracture healing time was 5.0±0.9 weeks in the auxiliary reduction group and 4.9±0.8 weeks in the manual reduction group ( t=-0.41, P>0.05). There were no significant statistical difference in the preoperative abduction angle and preoperative posterior tilt angle between the auxiliary reduction group and the manual reduction group ( P>0.05). The postoperative abduction angle and posterior tilt angle of the auxiliary reduction group (1.8°±3.1°, 1.2°±3.0°) were significantly lower than those of the manual reduction group (13.7°±6.5°, 6.8°±4.1°, t=-9.55, P<0.001; t=-7.42, P<0.001). Preoperatively, 61 cases (92%) were associated with a posterior tilt of the femoral head, and 30 (46%) of them had a posterior tilt angle of more than 10°. The length of femoral neck shortening at the last follow-up and the moderate and severe femoral neck shortening rate postoperatively in the auxiliary reduction group (1.4±2.1 mm, 0, and 3%) were significantly lower than those in the manual reduction group (8.1±4.8 mm, 38%, and 32%, P<0.05). Harris hip score at the last follow-up in the auxiliary reduction group 91.1±4.5 was significantly higher than those in the manual reduction group 85.5±5.4 ( t=4.54, P<0.001). The postoperative abduction angle and length of femoral neck shortening showed correlations with the Harris hip score respectively ( r=-0.551, -0.743; P<0.001). In the auxiliary reduction group, 1 case of broken temporary fixed Kirschner wire was removed by nucleus pulposus forceps, and the fracture site healed after surgery. In 2 cases, the Schanz screw loosened and pulled out during the reduction process, and the successful reduction was achieved after increasing the depth of the Schanz screw insertion, and no peri-Schanz screw fracture occurred. After surgery, 3 cases (1 case in the auxiliary reduction group and 2 cases in the manual reduction group) developed avascular necrosis of the femoral head (18 months, 18 months, and 2 years after surgery, respectively), femoral head collapse and severe shortening of the femoral neck, all of which underwent total hip arthroplasty. Conclusion:FNS after the reduction of the Schanz screw combined with the rod stick technique in the treatment of valgus-impacted femoral neck fracture has the advantages of effectively correcting preoperative abduction angle and posterior tilt angle and reducing the length of femoral neck shortening, and it can obtain satisfactory short and medium-term clinical efficacy.
