ABSTRACT

OBJETIVO: Probar una metodología de enseñanza-aprendizaje, instrumentos de medición y sistema de implementación de la ECOE en relación con lactancia materna, alimentación complementaria, crecimiento y consejería. MATERIAL Y MÉTODOS: Se estudió la adquisición de competencias sobre alimentación en menores de dos años en internos de pediatría aplicando la evaluación clínica objetiva estructurada (ECOE) antes y después del desarrollo de un proceso de enseñanza aprendizaje (PEA) estructurado. Se organizaron cuatro estaciones de evaluación de los aspectos centrales de alimentación y crecimiento, en un grupo de internos seleccionados al azar. RESULTADOS: Las cuatro estaciones de la ECOE se aplicaron sin dificultades antes y después del PEA. Los resultados mostraron una mejora en el rendimiento de los internos, de manera individual y de grupo; en este último las diferencias en la media fueron para alimentación complementaria pre 2,5 (DE 0,93) y post 5 (DE 2,39); consejería pre 5,75 (DE 1,49) y post 8,13 (DE 1,25); lactancia materna pre 12,63 (DE 2,5) y post 16,38 (DE 2) y velocidad de crecimiento pre 3,13 (DE 1,36) y post 3,38 (DE 0,92). Los resultados fueron estadísticamente significativos para los tres primeros rubros. CONCLUSIONES: En base a estos resultados se sugieren mejoras en el programa de enseñanza y se verifica la aplicabilidad de la ECOE en el internado del Hospital del Niño Dr. Ovidio Aliaga Uría.


OBJECTIVE: To test a teaching-learning methodology, measurement tools and OSCE implementation system in relation to breastfeeding, complementary feeding, growth and counseling. METHODOLOGY: The acquisition of competences was studied by applying objective structured clinical examination (OSCE) before and after the development of a structured teaching-learning process. Four assessment stations were organized considering central aspects on feeding and growth of children under two years of age, in a group of randomly selected students during medical internship. RESULTS: The four OSCE stations were applied without difficulties before and after the learning and teaching process. The results showed an improvement in the performance of interns, individually and in groups; in the latter, mean differences were: for complementary feeding pre 2.5 (SD 0.93) and post 5 (SD 2.39); counseling pre 5.75 (SD 1.49) and post 8.13 (SD 1.25); breastfeeding pre 12.63 (SD 2.5) and post 16.38 (SD 2) and growth velocity pre 3.13 (SD 1.36) and post 3.38 (SD 0.92). The results were statistically significant for the first three items. CONCLUSIONS: Based on these results, the authors suggest improvements in the teaching program, and verify the applicability of the OSCE for the evaluation of rotatory internship at the Hospital del Nino Dr. Ovidio Aliaga Uria.

ABSTRACT

No escopo da investigação de sob quais condições ocorre a aprendizagem e a emergência de operantes verbais, diferentes condições de ensino têm sido planejadas. Considerando que a população com Transtorno do Espectro Autista (TEA) apresenta frequentemente um repertório de operantes verbais ausente ou fracamente estabelecido, é necessário o estudo do planejamento de intervenções sistemáticas desses repertórios com condições de favorecer não só a aquisição de vocabulário, mas também o seu potencial gerativo de novas funções verbais. O Multiple Exemplar Instruction (MEI) é uma estrutura de ensino que tem demonstrado resultados promissores pela sua capacidade de estabelecer relações entre comportamentos de ouvinte e de falante e gerar novas respostas verbais. O objetivo deste estudo foi verificar os efeitos do MEI sobre o estabelecimento e integração entre os repertórios de ouvinte e de falante (ecoico, tato e mando). Participaram duas crianças com TEA, com idades de 7 e 8 anos e cuja comunicação era muito restrita e baseada em trocas de figuras. O ensino adotou três conjuntos com três estímulos cada. O ensino com cada conjunto foi realizado separadamente. Ora o ensino consistia no treino de ouvinte baseado em seleção, ora tentativas de ouvinte, ecoico, tato e mando, eram apresentadas de forma rotativa. Sondas múltiplas intercalaram os ensinos e verificaram os efeitos destes sobre o repertório de falante com os demais conjuntos. Os resultados demonstraram um aumento na emissão de respostas de ouvir e falar após o ensino por MEI para os dois participantes, ambos com repertório verbal restrito, mas o procedimento foi mais efetivo para uma das crianças...(AU)


In the scope of research about under what conditions the learning and emergency of verbal operants occurs, different teaching conditions have been planned. Considering that the population with Autistic Spectrum Disorder (ASD) often has a repertoire of verbal operants absent or poorly established, it is necessary to study the planning of systematic interventions in these repertoires with conditions to favor not only vocabulary acquisition, but also their generative potential of new verbal functions. The Multiple Exemplar Instruction (MEI) is a teaching structure that has shown promising results for its ability to establish relationships between listening and speaker behaviors and to generate new verbal responses. The objective of this study was to verify the effects of the MEI on the establishment and integration between the listener repertoires and the speaker (echoic, tact and mand). Two children with ASD, aged between 7 and 8 years old, participated in the study, whose communication was very restricted and based on exchanges of figures. The teaching adopted three sets with three stimuli each. Teaching with each set was carried out separately. The teaching consisted of the training of listener based on selection, sometimes attempts of listener, echoic, tact and mand, were presented in a rotating way. Multiple probes intercalated the teachings and verified the effects of these on the repertoire of speaker with the other sets. The results showed an increase in the emission of listening and speaking responses after MEI teaching for the two participants, both with restricted verbal repertoire, but the procedure was more effective for one of the children...(AU)


El el ámbito de la investigación de en qué condiciones se produce el aprendizaje y la aparición de operantes verbales, se han planificado diferentes condiciones de enseñanza. Teniendo en cuenta que la población con Trastorno del Espectro Autista (TEA) con frecuencia presenta un repertorio de operantes verbales ausentes o débilmente establecidos, es necesario estudiar la planificación de intervenciones sistemáticas en estos repertorios con condiciones para favorecer no solo la adquisición de vocabulario, sino también su potencial generativo de nuevas funciones verbales. La Instrucción Ejemplar Múltiple (MEI) es una estructura de enseñanza que ha mostrado resultados prometedores por su capacidad para establecer relaciones entre los comportamientos del oyente y el hablante y generar nuevas respuestas verbales. El objetivo de este estudio fue verificar los efectos del MEI en el establecimiento e integración entre los repertorios de oyentes y hablantes (eco, tacto y comando). Participaron dos niños con TEA, de 7 y 8 años, cuya comunicación era muy restringida y basada en intercambios de figuras. La enseñanza adoptó tres conjuntos con tres estímulos cada uno. La enseñanza con cada conjunto se llevó a cabo por separado. Algunas veces la enseñanza consistía en entrenar al oyente en base a la selección, a veces los intentos de escuchar, eco, tacto y comando, se presentaban de manera rotativa. Múltiples sondas intercalan las enseñanzas y verifican sus efectos en el repertorio de los hablantes con los otros grupos. Los resultados mostraron un aumento en la emisión de respuestas para escuchar y hablar después de la enseñanza de MEI para ambos participantes, ambos con repertorio verbal restringido, pero el procedimiento fue más efectivo para uno de los niños...(AU)

ABSTRACT

O presente estudo teve como objetivo descrever e analisar uma experiência pedagógica no Ensino Médio em aulas de Educação Física a partir dos Jogos Esportivos Coletivos (JEC). As aulas de Educação Física no Ensino Médio, geralmente apresentam alguns problemas pertinentes, tais como: privilégios aos alunos mais habilidosos em detrimento dos demais; conteúdos repetitivos; predomínio de competição exacerbada e, em alguns casos, mínima intervenção pedagógica. Como procedimento metodológico, realizamos pesquisa bibliográfica e pesquisa de campo, de caráter participante, sendo este um estudo qualitativo, que teve como técnica a utilização de questionários e diário de campo. A experiência foi realizada ao longo de 8 (oito) aulas, em uma turma de 2º ano do Ensino Médio, composta por 7 (sete) meninos e 11 (onze) meninas. Como resultado, consideramos que a abordagem sistêmica dos JEC possui uma interface com a educação para o lazer e o referencial cultural, podendo auxiliar na minimização de problemas existentes nas aulas como exclusão, desânimo, individualismo e mínima aprendizagem. Pudemos observar no início da experiência pedagógica uma estrutura social que era movida em torno dos mais habilidosos, que aos poucos foi se modificando com a intervenção pedagógica que utilizou o ensino sistêmico dos JEC. Ao oportunizar esse modelo de ensino, as aulas se tornaram diferentes, divertidas e menos excludentes, demonstrando a relevância de uma mediação pedagógica no Ensino Médio que: a) considere o contexto cultural dos educandos; b) valorize atividades que exploram o componente lúdico; c) oportunize diferentes experiências na esfera da cultura corporal de movimento; d) utilize o ensino sistêmico dos JEC na aprendizagem de uma modalidade esportiva e; e) contribua na formação de praticantes e espectadores críticos...(AU)


The present study aimed to describe and analyze a pedagogical experience in High School in Physical Education classes from the Collective Sports Games (JEC). Physical Education classes in High School generally present some pertinent problems, such as privileges to the most skilled students to the detriment of others, repetitive content, predominance of exacerbated competition and, in some cases, minimal pedagogical intervention. As a methodological procedure, we carried out bibliographic research and field research, of the participant character, being a qualitative study, which had as technique the use of questionnaires and field diary. The experiment was carried out during 8 (eight) classes, in a class of 2nd year of High School, composed of 7 (seven) boys and 11 (eleven) girls. As a result, we consider that the systemic approach of JEC has an interface with leisure education and cultural reference, and can help to minimize problems in class such as exclusion, discouragement, individualism and minimal learning. We could observe at the beginning of the pedagogical experience, a social structure that was moved around the most skilled, that gradually was changing with the pedagogical intervention that used the systemic teaching of the JEC. When we worked this teaching model, the classes became different, fun and less exclusionary, demonstrating the relevance of a pedagogical mediation in High School that: a) considers the cultural context of the students; b) value activities that explore the recreational component; c) give different experiences in the sphere of body culture of movement; d) use the JEC systemic teaching in the learning of a sports modality and e) contribute in the formation of critical practitioners and spectators...(AU)

ABSTRACT

Alzheimer's disease (AD) is pathologically characterized by a long progressive phase of neuronal changes, including accumulation of extracellular amyloid-β (Aβ) and intracellular neurofibrillary tangles, before the onset of observable symptoms. Many efforts have been made to develop a blood-based diagnostic method for AD by incorporating Aβ and tau as plasma biomarkers. As blood tests have the advantages of being highly accessible and low cost, clinical implementation of AD blood tests would provide preventative screening to presymptomatic individuals, facilitating early identification of AD patients and, thus, treatment development in clinical research. However, the low concentration of AD biomarkers in the plasma has posed difficulties for accurate detection, hindering the development of a reliable blood test. In this review, we introduce three AD blood test technologies emerging in South Korea, which have distinctive methods of heightening detection sensitivity of specific plasma biomarkers. We discuss in detail the multimer detection system, the self-standard analysis of Aβ biomarkers quantified by interdigitated microelectrodes, and a biomarker ratio analysis comprising Aβ and tau.

ABSTRACT

Canine adenovirus type 1 (CAV-1) causes infectious hepatitis in members of the family Canidae, including dogs. An indirect enzyme-linked immunosorbent assay (I-ELISA) that detects CAV-1 antibodies is required for large-throughput tests of dog sera. We collected 165 serum samples from dogs of Chungbuk and Gyeongbuk provinces between February 2016 and October 2018. The Korean CAV-1 vaccine strain CAV1V was propagated in Madin-Darby canine kidney (MDCK) cells and purified via Nuvia cPrime anion-exchange chromatography; the virus served as an I-ELISA antigen. Virus-neutralizing anti-CAV-1 titers in dog sera were measured using the virus neutralization (VN) method. The I-ELISA was optimized using purified CAV-1 antigen and serum samples. This kit was used to evaluate dog sera. The VN and I-ELISA data were compared. The sensitivity, specificity, and accuracy of the I-ELISA were 97.0%, 74.2%, and 92.7% compared to the VN assay, respectively. The I-ELISA data significantly correlated with those of VN (r = 0.88). These results suggest that the I-ELISA is useful for serosurveillance of CAV-1 in dog sera.

ABSTRACT

BACKGROUND: Acinetobacter baumannii infection is a significant health problem worldwide due to increased drug resistance. The limited antimicrobial alternatives for the treatment of severe infections by multidrug-resistant A. baumannii (MDRAB) make the search for other therapeutic options more urgent. Linalool, the major oil compound in Coriandrum sativum, was recently found to have high antibacterial activity against A. baumannii. The purpose of this study was to investigate the synergistic effect of linalool and colistin combinations against MDRAB and extensively drug-resistant A. baumannii (XDRAB).METHODS: A total of 51 strains of A. baumannii clinical isolates, consisting of 10 MDRAB and 41 XDRAB were tested. We determined the minimum inhibitory concentration (MIC) of linalool for the test strains using the broth microdilution method and searched for interactions using the time-kill assay.RESULTS: The time-kill assay showed that the linalool and colistin combination displayed a high rate of synergy (92.1%) (by synergy criteria 2), low rate of indifference (7.8%), and a high rate of bactericidal activity (74.5%) in the 51 clinical isolates of A. baumannii. The synergy rates for the linalool and colistin combination against MDRAB and XDRAB were 96% and 92.1%, respectively. No antagonism was observed for the linalool and colistin combination.CONCLUSION: The combination of linalool and colistin showed a high synergy rate, which may be beneficial for controlling MDRAB infections. Therefore, this combination is a good candidate for in vivo studies to assess its efficacy in the treatment of MDRAB infections.

ABSTRACT

PURPOSE: Allergen immunotherapy (AIT) induces immunological tolerance, and there is increasing evidence of the clinical efficacy of AIT in the treatment of allergic asthma. However, the optimal parameters for asthma control in clinical trials are still unclear. We investigated the efficacy of AIT with respect to changes in the inhaled corticosteroid (ICS) dose in patients with allergic asthma. METHODS: A total of 117 adults with allergic asthma who had used ICS for more than 1 year in a single tertiary hospital in Korea were included in this retrospective study. We compared the clinical parameters and outcomes between the AIT group (ICS with AIT, n = 48) and the non-AIT group (ICS without AIT, n = 69) by applying an inverse probability of treatment weighting method. The patients in the AIT group had received subcutaneous AIT monthly as a maintenance treatment for more than 1 year. The changes in the ICS dose from baseline were evaluated in the 2 groups for 3 years. RESULTS: The proportion of responders who discontinued or decreased in the ICS dose with achieving control status of asthma was significantly higher in the AIT group than in the non-AIT group throughout the study period (at 6 months, 52.1% vs. 24.6%; at 1 year, 70.8% vs. 34.7%; at 2 years, 89.5% vs. 35.6%; at 3 years, 96.3% vs. 51.2%). Treatment responses did not differ significantly by type of allergen (single- or multi-allergens or 3 different products) used throughout the study period. CONCLUSIONS: Irrespective of the type of allergen, long-term maintenance AIT helps to spare ICS dose and achieve better control in patients with allergic asthma in real-world clinical practice.

ABSTRACT

PURPOSE: The study aimed to assess the average time to return to play following surgery for chronic lateral ankle instability in athletes.METHODS: A literature search was conducted (1976 to 2019) by two independent reviewers using the Medline, Embase, and Cochrane library databases. Articles were retrieved by an electronic search using individual keywords (“lateral ankle instability,” “surgery,” “operation,” “return to sport,” “return to play”) and their combinations. Studies that met the inclusion criteria were assessed for pertinent data.RESULTS: Six randomized controlled trials were included in this analysis. The mean follow-up period was 44.8 months (range, 31.8–58.1 months) in 219 patients (male, 126; female, 113). The mean age was 23.2 years (range, 18.2–28.2 years). Different criteria for returning to sports were used in each paper. In the papers included in this study, different methods and definitions were used for the postoperative recovery method for lateral ankle instability injury. The average time until return to play was 16.53 weeks.CONCLUSION: There are limitations to the application of different surgical techniques and data from different athletes for chronic lateral ankle instability. However, these results suggest that sports physicians evaluate the surgical outcome and may be utilized as reference data for informing the athletes about their time until return.

ABSTRACT

The replacement of missing teeth, especially in the anterior region, is an essential part of dental practice. Fiber-reinforced composite resin bridges are a conservative alternative to conventional fixed dental prostheses or implants. It is a minimally invasive, reversible technique that can be completed in a single visit. The two cases presented herein exemplify the treatment of root-fractured anterior teeth with a natural pontic immediately after extraction.

ABSTRACT

PURPOSE: The Oral-anal Transit Test (OTT) is a simple method of obtaining information about colonic transit. We aim to assess the correlation of OTT with the neuromuscular integrity of the colon determined by colonic manometry (CM).METHODS: All patients who had OTT followed by CM were evaluated. Less than 6 of 24 markers remaining on OTT was considered normal. CM was performed per previously published guidelines. A normal CM was defined as at least one High Amplitude Propagating Contraction progressing from the most proximal sensor through the sigmoid colon.RESULTS: A total of 34 patients underwent both OTT and CM (44% male, age 4–18 years, mean 11.5 years, 97% functional constipation +/− soiling, Hirschsprung's Disease). Of normal and abnormal OTT patients, 85.7% (6/7) and 18.5% (5/27) respectively had normal CM. When all markers progressed to at least the sigmoid colon, this was 100% predictive against colonic inertia. Greater than 50% of patients with manometric isolated sigmoid dysfunction had markers proximal to the recto-sigmoid.CONCLUSION: OTT and CM are both valuable studies that assess different aspects of colonic function. OTT can be used as a screening test to rule out colonic inertia. However, the most proximal extent of remaining markers does not predict the anatomical extent of the manometric abnormality, particularly in isolated sigmoid dysfunction.

ABSTRACT

PURPOSE: To investigate ocular fatigue after the use of a head-mounted display (HMD)-type virtual reality device.METHODS: Healthy adult volunteers were examined for ocular fatigue before and after watching videos for 10 min with an HMD-type virtual reality device. Subjective ocular fatigue was measured using a questionnaire. Objective fatigue was measured using the critical flicker fusion frequency (CFF), high frequency component of accommodative microfluctuation, and accommodation amplitude. The accommodation amplitude was measured using the push-up method and the dynamic measurement mode of the autorefractometer. Changes in the spherical equivalent were also measured.RESULTS: The questionnaire-based subjective ocular fatigue increased (p = 0.020) after use of the HMD device. In the dominant eye, the high frequency component of accommodative microfluctuation increased (p < 0.05). The accommodation amplitude using the push-up method was decreased in the nondominant eye (p = 0.007), and temporary myopia was observed (p < 0.05). However, there was no increase in ocular fatigue in the CFF or the accommodation amplitude using the dynamic measurement mode, which showed no significant difference before and after using the HMD device (p > 0.05).CONCLUSIONS: A subjective test and some objective tests suggested that use of the HMD-type virtual reality display increased ocular fatigue. However, no increase in ocular fatigue was measured using CFF nor in the accommodation amplitude using the dynamic measurement mode which was a limitation of the study. More studies with the aim to alleviate ocular fatigue after using HMD-type virtual reality devices are therefore needed.

ABSTRACT

PURPOSE: We developed a novel method for measurement of hyperacuity and verified the utility thereof.METHODS: We developed a three-dimensional (3D) hyperacuity test using a 3D liquid crystal flat screen, a left- and right-image polarized display, and liquid crystal shutter glasses. We tested the technique in three groups: normal (n = 48), with cataracts (n = 14), and with macular disease (n = 35). We used a chart consisting of five dots and a reference line. Of the five dots, one was variably shifted from the other dots. A chart was presented to one eye and the reference line or blank image to the other eye; a subject scored positive when the dot in the unusual position was recognized.RESULTS: Hyperacuity was measured in terms of the reference line seen by the reference eye (RR), a blank image seen by the reference eye (RB), the reference line seen by the contralateral eye (CR), and a blank image seen by the contralateral eye (CB). All test scores were significantly lower when the reference line was seen than not (RR vs. RB and CR vs. CB; p < 0.01, respectively). For the RR and CR tests, no significant difference was apparent between the normal and cataracts group (p = 0.553, p = 0.494) but such differences were evident between the normal and macular disease groups (p = 0.028, p = 0.002). Also, visualization of the reference line by the reference and contralateral eyes did not differ (p > 0.05).CONCLUSIONS: Measurement of hyperacuity using our new method was not affected by media opacity but was significantly affected by macular disease. Presentation of a reference line facilitated hyperacuity assessment.

ABSTRACT

PURPOSE: To report a patient with a pseudophakic bullous keratopathy (PBK) who underwent Descemet's membrane stripping endothelial keratoplasty (DSEK) with manual preparation of the donor corneal graft.CASE SUMMARY: A 61-year-old female presented with visual disturbance in her right eye. Five months prior, she was treated with phacoemulsification and intraocular lens exchange surgery of the right eye, and a very severe corneal edema was revealed by slit-lamp examination. We diagnosed PBK and planned DSEK with manual preparation of a donor corneal graft because of the non-availability of a microkeratome or a femtosecond laser. After making the corneal graft using an artificial anterior chamber, crescent knife and cornea dissector, the keratoplasty proceeded using the graft. Three months after surgery, her graft was well-maintained on the right eye. The patient's visual acuity was 0.3, and the corneal endothelial cell count was 1,844/mm².CONCLUSIONS: Manual preparation of the donor corneal graft for DSEK is suitable as a second choice treatment method when the availability of surgical devices is limited.

ABSTRACT

The prevalence of benign prostatic hyperplasia (BPH) is rising with Korea becoming an aging society. As patients age, their comorbidities and the risks associated with anesthesia increase. Recently, there has been an increasing concern regarding sexual function after surgery. As a result, interest in minimally invasive surgery for BPH that does not require anesthesia or affect sexual function has grown. This review article introduces newly developed minimally invasive surgeries for BPH divided into four categories based on the strategy—mechanical, anatomical, atrophic, and laparoscopic. Here, the mechanisms for each surgical method have been introduced. Furthermore, recent representative studies of these procedures with a focus on randomized controlled trials and meta-analyses have also been reviewed. Side effects related to sexual function have also been mentioned briefly along with the efficacy and indication for robotic BPH surgery, which has recently been attracting attention. However, these newer, minimally invasive procedures require additional comparative randomized controlled trials and long-term results to produce more robust evidence for their use.

ABSTRACT

PURPOSE: This study compared the clinical and radiological results between two groups of patients with percutaneous fixation or conventional fixation after hardware removal.MATERIALS AND METHODS: The study analyzed 68 patients (43 open fixation and 43 percutaneous screw fixation [PSF] 25) who had undergone fixation for unstable thoracolumbar fractures. The radiologic results were obtained using the lateral radiographs taken before and after the fixation and at the time of hardware removal. The clinical results included the time of operation, blood loss, time to ambulation, duration of the hospital stay and the visual analogue scale.RESULTS: The percutaneous pedicle screw fixation (PPSF) group showed better results than did the conventional posterior fixation (CPF) group (p<0.05) in regard to the perioperative data such as operation time, blood loss, and duration of the hospital stay. There were no significant differences in wedge angle, local kyphotic angle, and the ΔKyphotic angle on the postoperative plane radiographs between the two groups (p>0.05). There were no significant differences in the wedge angle and local kyphotic angle after implant removal (p>0.05) between the two groups as well. However, there were significant differences in the segmental montion angle (p<0.001), and the PPSF group showed a larger segmental motion angle than did the CPF group (CPF 1.7°±1.2° vs PPSF 5.9°±3.2°, respectively).CONCLUSION: For the treatment of unstable thoracolumbar fractures, the PPSF technique could achieve better clinical results and an improved segmental motion angle after implant removal within a year than that of the conventional fixation method.

ABSTRACT

PURPOSE: The purpose of this study was to compare the clinical and radiological outcomes of locking compression plate (LCP)-screw fixation and tension band wiring (TBW) fixation in isolated lateral malleolar fractures.MATERIALS AND METHODS: From May 2016 to August 2018, 52 patients with isolated lateral malleolar fracture were retrospectively reviewed. They were divided into 30 cases of the LCP fixation group (Group I) and 22 cases of the TBW fixation group (Group II). The clinical and radiological results of those groups were compared. Pearson chi-square tests and independent t-tests were used in the statistical analysis.RESULTS: The mean length of the surgical incision was 8.3 cm in Group I and 4.9 cm in Group II. Radiological union was obtained at a mean of 8.4 weeks in both groups. The mean American Orthopaedic Foot and Ankle Society score was 90 (range, 85–97) and 92 (range, 85–100) in Groups I and II, respectively, at the last follow up.CONCLUSION: Both the LCP-screw and TBW techniques revealed excellent results in isolated lateral malleolar fractures. The tension band technique may be a fine alternative method of fixation in the treatment of isolated lateral malleolar fracture.

ABSTRACT

Although the incidence of postoperative periprosthetic femoral fractures after hip arthroplasty is expected to increase, these complex fractures are still challenging complications. To obtain optimal results for these fractures, thorough clinical and radiographic evaluation, precise classification, and understanding of modern management principles are mandatory. The Vancouver classification system is a simple, effective, and reproducible method for planning proper treatments of these injuries. The fractures associated with a stable femoral stem can be effectively treated with osteosynthesis, though periprosthetic femoral fractures associated with a loose stem require revision arthroplasty. We describe here the principles of proper treatment for the patients with periprosthetic femoral fractures as well as how to avoid complications.

ABSTRACT

Recently, as the elderly population increases, the incidence of total knee arthroplasty has increased, with a concomitant increase in the frequency of periprosthetic fractures. To determine the treatment plan for fractures, the treatment method should be determined by the patient's age, osteoporosis, fixation status of the implant, and type of fracture. In recent years, operative treatment with reduction and stable fixation, rather than non-operative treatment, was used to promote early joint movement and gait. On the other hand, it is necessary to select an appropriate operative method to reduce complications of surgery, such as nonunion and infection, and expect a good prognosis. In this review, periprosthetic fractures were divided into femur, tibia, and patella fractures, and their causes, risk factors, classification, and treatment are discussed.

ABSTRACT

OBJECTIVES: Pentoxifylline (PTX) is a methylxanthine derivative that has been implicated in the pathogenesis of peripheral vessel disease and intermittent lameness. The purpose of this study was to investigate the effect of PTX and tocopherol in patients diagnosed with osteoradionecrosis (ORN), bisphosphonate-related osteonecrosis of the jaw (BRONJ), and chronic osteomyelitis using digital panoramic radiographs.MATERIALS AND METHODS: This study was performed in 25 patients who were prescribed PTX and tocopherol for treatment of ORN, BRONJ, and chronic osteomyelitis between January 2014 and May 2018 in Seoul National University Dental Hospital. Radiographic densities of the dental panorama were compared prior to starting PTX and tocopherol, at 3 months, and at 6 months after prescription. Radiographic densities were measured using Adobe Photoshop CS6 (Adobe System Inc., USA). Blood sample tests showing the degree of inflammation at the initial visit were considered the baseline and compared with results after 3 to 6 months. Statistical analysis was performed using the Mann–Whitney test and repeated measurement ANOVA using IBM SPSS 23.0 (IBM Corp., USA).RESULTS: Eight patients were diagnosed with ORN, nine patients with BRONJ, and the other 8 patients with chronic osteomyelitis. Ten of the 25 patients were men, average age was 66.32±14.39 years, and average duration of medication was 151.8±80.65 days (range, 56–315 days). Statistically significant increases were observed in the changes between 3 and 6 months after prescription (P<0.05). There was no significant difference between ORN, BRONJ, and chronic osteomyelitis. Only erythrocyte sedimentation rate (ESR) was statistically significantly lower than before treatment (P<0.05) among the white blood cell (WBC), ESR, and absolute neutrophil count (ANC).CONCLUSION: Long-term use of PTX and tocopherol can be an auxiliary method in the treatment of ORN, BRONJ, or chronic osteomyelitis in jaw.
