Research progress on invasive cervical resorption / 口腔疾病防治

@#Tooth absorption can be divided into physiological absorption and pathological absorption. Root absorption of mature deciduous teeth is physiological absorption. Pathological absorption includes internal absorption and external absorption. Internal absorption, also known as intramedullary absorption, includes inflammatory absorption and alternative absorption. External tooth absorption originates from the outer surface of the root or the neck of the tooth and can be divided into inflammatory absorption, alternative absorption, pressure resorption and invasive cervical resorption. Invasive cervical resorption (ICR) is pathological damage caused by many factors, which usually begins in the cemento-enamel junction and extends peripherally or horizontally in the dentin. It hardly invades the pulp. Orthodontic devices, trauma, bleaching, systemic diseases, and the use of certain medications can all lead to invasive cervical resorption. The clinical manifestations of ICR are usually asymptomatic or not obvious, and most of which are found in imaging examinations. Because caries and internal absorption are often misdiagnosed through plain apical radiography, cone beam computed tomography (CBCT) can help to better understand the situation of invasive cervical resorption. Because the pathogenesis and etiology of invasive cervical resorption are not fully understood, clinical negligence and inadequate treatment of invasive cervical resorption can even cause unnecessary tooth loss. This article reviews the latest research progress on the histopathologic features, pathogenic mechanism, susceptibility factors, diagnosis and treatment of ICR, with special emphasis on susceptibility factors and their mechanisms.

Ligadura de la arteria lingual: estrategia para hemorragias por lesión de la arteria en la base de la lengua: informe de dos casos / Lingual Artery Ligation: Strategy for Bleeding from Artery Injury at the Base of the Tongue: Report of Two Cases

La hemorragia producida por lesión de la arteria lingual en la base de la lengua por cirugías o por tumores es infrecuente. La mayor frecuencia en la indicación de abordajes transorales para tratar diferentes patologías que afectan la orofaringe requiere que el equipo quirúrgico tenga experiencia en el manejo de esta complicación. La ligadura de la arteria lingual en el cuello es una técnica quirúrgica muy eficaz para solucionar la hemorragia, pero es importante conocer las posibles variantes anatómicas que puede tener la arteria en su trayecto cervical. Debido a su baja incidencia se propone como objetivo describir dos casos clínicos de pacientes que tuvieron hemorragias graves por lesión de la arteria lingual en la base de la lengua, producidas por daño quirúrgico y por erosión por tumor. [AU]

The bleeding caused by injury to the lingual artery at the base of the tongue due to surgery or tumors is infrequent. The increased frequency in the indication of transoral approaches to treat different pathologies affecting the oropharynx requires the surgical team to have experience in managing this complication. Ligation of the lingual artery in the neck is a very effective surgical technique to solve the bleeding; however, it is essential to be aware of the possible anatomical variants the artery may have in its cervical trajectory. Due to its low incidence, we propose to describe two clinical cases of patients who had severe bleeding due to a lesion of the lingual artery at the base of the tongue, produced by surgical damage and erosion due to a tumor.

Evaluation of the Radiological Anatomy of the Temporal Bone Air Spaces and Morphometric Analysis in Turkish Healthy Adults / Evaluación de la Anatomía Radiológica de los Espacios Aéreos del Hueso Temporal y Análisis Morfométrico en Adultos Turcos Sanos

SUMMARY: The temporal bone is a complicate structure which located on the lateral skull. The objective of the present study was to determine the temporal bone air spaces' morphometry, morphology, and pneumatization in Turkish healthy adult people. This retrospective observational study was carried out from 82 subjects (47 males, 35 females) aged 18-69 years. The external auditory canal and related structures' diameters and the volume of these areas were evaluated. The means and standard deviations of the Meatus acusticus externus length (MAEL), meatus acusticus externus pars cartilaginea length (MAEcL), meatus acusticus externus pars ossea length (MAEoL), meatus acusticus externus pars cartilaginea surface (MAEcS), meatus acusticus externus pars ossea surface (MAEoS), meatus acusticus externus volume (MAEV), meatus acusticus externus pars cartilaginea volume (MAEcV), meatus acusticus externus pars ossea volume (MAEoV), processus mastoideus air cells volume (PMACV), cavum tympani volume (CTV), and temporale pneumatic spaces volume (OTPSV) were found as 23.21±3.70 mm, 12.69±3.72 mm, 7.80±3.70 mm, 669.89±107.7 mm2, 267.50±30.51 mm2, 743.50±119.6 mm3, 971.97±156.69 mm3, 419.51±48.67 mm3, 5915.93±650.34 mm3, 673.48±91.93 mm3, 7813.34±717.49 mm3 have found in 82 subjects, respectively. In this paper, the morphometric and volume properties of the temporal bone cavities measurements were significantly higher in males than females. These results may both provide reference values of Turkish healthy population, and lead to decrease potential surgical complications about temporal and mastoid regions.

El hueso temporal es una compleja estructura ubicada en el parte lateral del cráneo. El objetivo del presente estudio fue determinar la morfometría, morfología y neumatización de los espacios aéreos del hueso temporal en individuos adultos turcos sanos. Este estudio observacional retrospectivo que se llevó a cabo en 82 sujetos (47 hombres, 35 mujeres) de entre 18 y 69 años. Se evaluaron los diámetros del meato acústico externo y las estructuras relacionadas y el volumen de estas áreas. Las medias y las desviaciones estándar de la longitud del meato acústico externo (MAEL), la longitud de la parte cartilaginosa del meato acústico externo (MAEcL), la longitud de la parte ósea del meato acústico externo (MAEoL), la superficie de la parte cartilaginosa del meato acústico externo (MAEcS), la superficie de la parte ósea del meato acústico externo (MAEoS), volumen del meato acústico externo (MAEV), volumen de la parte cartilaginosa del meato acústico externo (MAEcV), volumen de la parte ósea del meato acústico externo (MAEoV), volumen de las células aéreas del proceso mastoideo (PMACV), volumen del cavum tympani (CTV) y el volumen de los espacios neumáticos temporales (OTPSV) se encontró como 23,21 ± 3,70 mm, 12,69 ± 3,72 mm, 7,80 ± 3,70 mm, 669,89 ± 107,7 mm2, 267,50 ± 30,51 mm2, 743,50 ± 119,6 mm3, 971,97 ± 156,69 mm3, 419,5. 1±48,67 mm3, 5915,93 ± 650,34 mm3, 673,48 ± 91,93 mm3, 7813,34 ± 717,49 mm3, respectivamente. En este artículo, las propiedades morfométricas y de volumen de las mediciones de las cavidades del hueso temporal fueron significativamente mayores en hombres que en mujeres. Estos resultados pueden proporcionar valores de referencia de la población sana turca y conducir a una disminución de las posibles complicaciones quirúrgicas en las regiones temporal y mastoidea.

Reporte de caso: reabsorción cervical externa

La reabsorción cervical externa es una patología poco frecuente y difícil de detectar, lo que complica el diagnóstico y pronóstico. El proceso destructivo provoca pérdida progresiva de tejido, comenzando en la superficie radicular y avanzando hacia la pulpa. Este tipo de reabsorción ocurre principalmente en la región cervical de la raíz dental pudiendo confundirse con lesión de caries radicular. El objetivo del reporte de caso es ilustrar al equipo de salud la existencia de esta condición y destacar la importancia del diagnóstico temprano y diferencial para evitar llegar a la pérdida del diente afectado.

External cervical resorption is a rare and difficult-to-detect condition, which complicates diagnosis and prognosis. The destructive process causes progressive loss of tissue, starting at the root surface and advancing towards the pulp. This type of resorption primarily occurs in the cervical region of the dental root and can be confused with root caries. The case report aims to inform the healthcare team about the presence of this condition and emphasizes the significance of early and differential diagnosis to prevent the loss of the affected tooth.

Abordagem de incisivos centrais superiores traumatizados: relato de caso / Approach to traumati zed maxillary central incisors: case report

Introdução: O traumatismo dentário é uma ocorrência frequente durante a infância e adolescência. Geralmente, o diagnóstico acontece de forma tardia, devido à falta de conhecimento da população. Cada tipo de trauma necessita de uma conduta única e especializada. Nos casos de comprometimento pulpar, é necessário cuidado quanto à escolha da técnica a ser empregada, bem como a seleção da medicação intracanal que, por sua vez, apresenta grande interferência no sucesso do tratamento. Não obstante o avanço das técnicas de instrumentação, a troca da medicação entre as sessões nesses casos é mandatória. Relato de caso: Um paciente, sexo masculino, em idade escolar (15 anos) apresentou-se ao serviço de saúde bucal com relato de escurecimento e dores na mastigação após trauma dentário durante a infância. Os testes de vitalidade pulpar revelaram necrose pulpar, com resultado negativo no teste térmico e positivo na percussão. O exame radiológico evidenciou uma lesão apical, juntamente com reabsorção externa no elemento 21, confirmado em tomografia. O paciente foi submetido a um tratamento endodôntico. Resultado: Após o tratamento, foi solicitado novo exame tomográfico, em que se evidenciou um processo de cicatrização óssea no periápice e reabsorção por substituição na lesão cervical. Conclusão: A partir deste caso clínico, pôde-se evidenciar a importância do diagnóstico adequado, do manejo e da técnica endodôntica eficaz na resolução de problemas decorrentes de traumas dentários em pacientes jovens.

Introduction: Dental trauma is a frequent occurrence during childhood and adolescence. Generally, diagnosis happens late, due to lack of knowledge among the population. Each type of trauma requires a unique and specialized approach. In cases of pulp involvement, care must be taken when choosing the technique to be used, as well as the selection of intracanal medication, which, in turn, has a major impact on the success of the treatment. Despite advances in instrumentation techniques, changing medication between sessions in these cases is mandatory. Case report: A male patient of school age (15 years old) presented to the oral health service with reports of darkening and pain when chewing following dental trauma during childhood. Pulp vitality tests revealed pulp necrosis, with a negative result in the thermal test and positive in percussion. The radiological examination showed an apical lesion, together with external resorption in element 21, confirmed on tomography. The patient underwent endodontic treatment. Result: After treatment, a new tomographic examination was requested, which showed a process of bone healing in the periapex and resorption by replacement in the cervical lesion. Conclusion: From this clinical case, it was possible to highlight the importance of adequate diagnosis, management, and effective endodontic technique in solving problems arising from dental trauma in young patients.

Outcomes of 8 × 8 mm osteotomy in powered external dacryocystorhinostomy

Purpose: To study the endoscopic ostium characteristics and outcome of 8 × 8 mm osteotomy in external dacryocystorhinostomy (DCR) using the microdrill system. Methods: This prospective interventional pilot study was performed on 40 eyes of 40 patients with primary acquired nasolacrimal duct obstruction (NLDO) from June 2021 to September 2021 in patients undergoing external DCR. An 8 × 8 mm osteotomy was performed using round, cutting burr attached to a microdrill system. Success was defined as patent ostium on lacrimal syringing (anatomical) and a Munk score <3 (functional) at 12 months. Postoperative endoscopic ostium evaluation was done using a modified DCR ostium (DOS) scoring system at 12 months. Results: The mean age of the study participants was 42.41 ± 11.77 years and the male?to?female ratio was 1:4. The mean duration of surgery was 34.15 ± 1.66 minutes and that for osteotomy creation was 2.5 ± 0.69 minutes. The mean intraoperative blood loss was 83.37 ± 11.89 ml. Anatomical and functional success rates were 95% and 85%, respectively. The mean modified DOS score was “excellent” in 34 patients (85%), “good” in 1 patient (2.5%), “fair” in 4 patients (10%), and “poor” in 1 patient (2.5%). Complications included nasal mucosal injury in 10% (4/40) of patients, complete cicatricial closure of ostium in 2.5% (1/40), incomplete cicatricial closure in 10% (4/40), nasal synechiae in 5% (2/40), and canalicular stenosis in 2.5% (1/40). Conclusion: An 8 × 8 mm–sized osteotomy created by powered drill and covered by lacrimal sac–nasal mucosal flap anastomosis in external DCR is an effective technique that has minimal complications and shorter surgical time

A STUDY OF OUTCOMES OF DISTAL END RADIUS FRACTURES MANAGED BY EXTERNAL FIXATOR

BACKGROUND: Fractures of the distal radius continue to be the most common skeletalinjuries treated by the orthopedic surgeon. Unstable fractures of the distal part of the radiushave shown an inherent tendency towards loss of reduction after non-operative treatment.External skeletal fixation has been popular for the treatment of displaced, unstable fracturesof the distal part of the radius because it combines a minimally invasive procedure withreduction by ligamentotaxis.METHOD: A retrospective study of 70 patients of fracture of distal end radius treated withexternal fixator came to OPD at tertiary care hospital during the study period of 2 years fromJuly 2020 to June 2022, were included in the study after obtaining permission frominstitutional review board.RESULT: All 70 patients were assessed in the form of the functional and radiologicaloutcome based on Subjective evaluation by Modified Demerit Point System of Gartland andWerley (Functional) and Lidstorm and Frykman Criteria modified by Sarmiento(Anatomical). We obtained “excellent” results in 47.15%; “good” in 35.72% cases; “fair” in14.28% and “poor” in 2.85% cases with a mean G & W score of 6.35.CONCLUSION: Finding of this study shows that external fixator is an easy, cost effective,reliable and most suitable treatment in treating intraarticular and unstable extraarticular distalend radial fractures by the principle of ligamentotaxis.

Colesteatoma del conducto auditivo externo: Experiencia de 5 años Hospital del Salvador / External ear canal cholesteatoma: 5-year experience Hospital del Salvador

Introducción: El colesteatoma del conducto auditivo externo (CCAE) es una estructura quística revestida por epitelio escamoso estratificado queratinizado que tiene la capacidad de invadir y erosionar localmente al hueso temporal. Su incidencia es de 0,19 a 0,3/100.000 habitantes siendo 60 veces menos frecuente que el de oído medio. Objetivo: Describir las características epidemiológicas, clínicas, imagenológicas y tratamiento de los pacientes diagnosticados con CCAE en el Servicio de Otorrinolaringología Hospital del Salvador. Material y Método: Se presenta una serie de ocho casos clínicos recopilados durante el período 2017 y 2021. Se realizó revisión de fichas clínicas, biopsias y tomografías computadas de oídos (TC oídos). Se describen los hallazgos y tratamiento efectuado. Resultados: El promedio de edad fue de 65,6 años, correspondiente a 5 mujeres y 3 hombres con presencia de tabaquismo y diabetes en la mitad de los casos. Los síntomas y signos más frecuentes fueron otalgia e hipoacusia seguido de otorrea. 7 pacientes se presentaron con tímpano íntegro y el compromiso de la pared inferior del conducto se evidenció en 6 de 8 pacientes. La TC oídos mostró erosión ósea del conducto, con o sin compromiso de estructuras adyacentes, en todos los casos y el diagnóstico histológico fue efectuado en el 100% de los pacientes. Se privilegió el tratamiento conservador mediante curaciones óticas periódicas asociado a ácido salicílico al 3% y/o antibióticos tópicos en 6/8 pacientes. Conclusiones: El CCAE es una entidad poco frecuente sin signos ni síntomas patognomónicos por lo que el diagnóstico histológico junto con el estudio imagenológico es perentorio. El tratamiento conservador es una alternativa terapéutica válida que ofrece buenos resultados en pacientes con adecuada adherencia al tratamiento y posibilidad de seguimiento estricto.

Introduction: External ear canal cholesteatoma (EECC) is a cystic structure lined by keratinized stratified squamous epithelium that has the ability to locally invade and erode the temporal bone. Its incidence is 0.19 to 0.3 / 100,000 habitants, being 60 times less frequent than that of the middle ear. Aim: To describe the epidemiological, clinical, imaging and treatment characteristics of patients diagnosed with EECC in the Hospital del Salvador ENT department. Material and Methods: A series of eight clinical cases collected during the period 2017 and 2021 is presented. A review of clinical records, biopsies and computed tomography of the ear (ear CT) was carried out. The findings and treatment carried out are described. Results: The average age was 65.6 years corresponding to 5 women and 3 men with the presence of smoking and diabetes in half of the cases. The most frequent symptoms and signs were earache and hearing loss followed by otorrhea. 7 patients presented with an intact eardrum and compromise of the inferior wall of the canal was evidenced in 6 of 8 patients. Ears CT showed bone erosion of the canal with or without compromise of adjacent structures in all cases and the histological diagnosis was made in 100% of the patients. Conservative treatment with periodic ear dressings associated with 3% salicylic acid and / or topical antibiotics was favored in 6/8 patients. Conclusion: EECC is a rare entity without pathognomonic signs or symptoms, therefore the histological diagnosis together with the imaging study is peremptory. Conservative treatment is a valid therapeutic alternative that offers good results in patients with adequate adherence to treatment and the possibility of strict follow-up.

A rare case of migrainous left bell抯 palsy after migrainous right external ophthalmoplegia - A case report

Migraine increased the risk of Bell palsy in the total population. Among migraine patients, between ?30 and <60 years old are at an increased risk of Bell palsy. A migraine is a primary headache characterized by recurrent headache attacks triggered by various factors. As much as 10% of the global population is thought to experience migraine headaches. It was earlier considered that migraine headaches were triggered by the dilation of cerebral vessels, and the recent evidence supports that migraine attacks can also occur in the absence of vasodilation. According to the researchers, the direct neural effects from the trigeminal nerve to the facial nerve could contribute to the risk of facial palsy among patients with migraine. An alteration of the trigeminovascular function has been suggested to trigger migraines. The neurogenic inflammation of the facial nerve trunk caused by its proximity to the dilated posterior auricular/ stylomastoid/ occipital and superficial temporal arteries during a migraine attack leads to a temporary lower motor neuron type of paresis of the muscles supplied by the facial nerve. We herewith report a rare case of migrainous left Bell抯 palsy after migrainous right external ophthalmoplegia, treated with Sumatriptan.

Choroidal metastasis: Radiation and bevacizumab at presentation

Purpose: To reveal early intervention outcomes for patients describing with choroidal metastasis. Methods: A retrospective interventional case series on 27 eyes of 22 patients treated for choroidal metastasis with external beam radiation therapy (EBRT) With and without intravitreal injections. The prescribed radiation dose was a mean and median 30 Gy (range of 30–40 Gy in 180–200 cGy daily fractions). Outcome measures included change in tumor thickness, subretinal fluid, visual acuity, radiation oculopathy, and survival. Results: Decreased vision was the most common presenting symptom (n = 20/27, 74%). Pre?treatment vision for subfoveal lesions was a mean 20/400, median 20/200, and range 20/40 to hand motions (HM). Pre?treatment vision for extrafoveal tumors were a mean 20/40, median 20/25, range 20/20 to counting fingers (CF) which improved to a mean 20/32, median 20/20, range 20/12.5 to 20/200. Local control, with ultrasonographic height regression (44.5%; mean: 2.7–1.5 mm), was observed in all eyes at mean follow?up of 16 months (range: 1–72 months). Intravitreal anti?vascular endothelial growth factor (anti?VEGF) was given in nine cases (n = 9/27, 33%) to slow the growth of the metastasis and suppress their exudative detachments and to treat radiation maculopathy in 10 cases (n = 10/27, 37%). Late radiation complications included keratoconjunctivitis sicca in four cases (n = 4/27, 15%), exposure keratopathy in two cases (n = 2/27, 7%), and radiation retinopathy in 10 cases (n = 10/27, 37%). Of the 23 phakic eyes, four (n = 4, 17%) developed cataract. Conclusion: Radiation therapy with or without intravitreal anti?VEGF injections was a safe and effective treatment for choroidal metastasis. It was associated with local tumor control, reduction of secondary retinal detachments, and vision preservation.

Percutaneous Suspensory Stabilization of Chronic Distal Radioulnar Joint (DRUJ) Dislocation Using an Adjustable Loop Endobutton Construct: Case Report / Fixação suspensiva percutânea de luxação crônica da articulação radioulnar distal (ARUD) usando um dispositivo de endobutton de laço ajustável: Relato de caso

Abstract Chronic distal radioulnar joint (DRUJ) dislocation has been treated historically with complex osteotomies and reconstructive procedures, often resulting in intractable stiffness and loss of function. It is desirable to use a technique of fixation that will not only restore the wrist biomechanics but also be cosmetically appealing to the individual. We present a novel technique of reduction and fixation of a chronically dislocated DRUJ in a 26-year-old male using a minimally invasive approach, with successful restoration of DRUJ function and no postoperative complications.

Resumo Luxação crônica da articulação radioulnar distal (ARUD) foi tratada historicamente com osteotomias complexas e procedimentos reconstrutivos, geralmente resultando em rigidez intratável e perda de função. É desejável usar uma técnica de fixação que não apenas restaure a biomecânica do punho, mas também seja esteticamente atraente para o indivíduo. Apresentamos uma nova técnica de redução e fixação de uma ARUD deslocada cronicamente em um homem de 26 anos, usando uma abordagem minimamente invasiva, com restauração bem-sucedida da função da ARUD e sem complicações pós-operatórias.

Effect Of Pranayama on Reducing the Level of Fatigue During External Radiation Therapy Among the Patients in A Cancer Hospital of Guwahati, Assam India

Introduction: Cancer related fatigue, a problem often less understood and under-diagnosed. It is imperative to find non-invasive and non-pharmacological solutions for managing it. The aim of the study was to assess the effect of pranayama on reducing the level of Fatigue during External Radiation Therapy (ERT) among the patients in a selected cancer hospital of Guwahati, Assam. Materials and methods: The study adopted Quantitative evaluative approach; randomized pre-test post-test control group design. Simple random sampling technique without replacement was used and 84 cancer pa-tients were equally divided in control group (42) and experimental group (42). The pre-test level of fatigue was assessed from both the groups and pranayama as intervention was given to experimental group. Result: Pranayama was found to be effective in patients receiving ERT. It was found that following pranaya-ma, majority in experimental group 41 (97.6%) had mild level of fatigue whereas in control group 27 (64.3%) experienced severe level of fatigue. There is significant mean difference in the experimental group as com-pared to control group after the intervention of pranayama (t=17.99, df=41, p-value=<.001). Conclusion: Pranayama is found to be effective intervention in reducing fatigue among cancer patients re-ceiving ERT.

Ear shut and Dentistry: ethical and legal approach / Ear shut e Odontologia: abordagem ética e legal

Introduction: As a health science, dentistry seeks to raise self-esteem and improve patients' quality of life. However, the emergence of the aesthetic procedure "ear shut," which proposes correcting protruding ears without surgery, has raised ethical and legal doubts in the dental profession, especially concerning the limits of professional activity. Objective: To conduct a survey of the laws, norms, and resolutions on the area of performance of dental surgeons, as well as to discuss the limits and consequences of their extrapolation from the perspective of the procedure propagated as "ear shut." Method: A search was carried out for administrative norms on the Federal Council of Dentistry (CFO) websites and the Federal Council of Medicine and legal provisions on the Portal da Legislação website. Results: In the civil sphere, the disclosure of procedures such as the "ear shut" can characterize a promise of result and lead to judicial accountability. Exceeding professional boundaries constitutes an illegal exercise and a crime under the Brazilian Penal Code. In addition to not covering the area of clinical practice of dentists, at the administrative level, CFO Resolutions No. 198/2019 and No. 230/2020 emphasize that ear procedures are not part of the scope of procedures relevant to Dentistry and may lead to ethical infractions and consequent administrative proceedings. Conclusion: At present, based on the skills, prohibitions, rights, and duties of dentists, it can be stated that performing the "ear shut" by these professionals confronts civil, criminal, and administrative obligations.

Introdução: Como ciência da saúde, a Odontologia busca elevar a autoestima e melhorar a qualidade de vida dos pacientes. Entretanto, o surgimento do procedimento estético "ear shut", que propõe a correção da orelha em abano sem cirurgia, gerou dúvidas de ordem ética e legal na classe odontológica, sobretudo no que diz respeito aos limites de atuação profissional. Objetivo: Realizar o levantamento das leis, normativas e resoluções sobre a área de atuação dos cirurgiões-dentistas, bem como discutir os limites e as consequências de sua extrapolação sob a perspectiva do procedimento propagado como "ear shut". Método: Foi realizada uma busca de normas administrativas nos sites do Conselho Federal de Odontologia (CFO) e do Conselho Federal de Medicina, bem como de dispositivos legais no site Portal da Legislação. Resultados: Em âmbito cível, a divulgação de procedimentos como o "ear shut" pode caracterizar promessa de resultado e levar à responsabilização judicial. Ultrapassar os limites profissionais constitui exercício ilícito e constitui crime segundo o Código Penal Brasileiro. Além de não abranger a área de atuação clínica dos cirurgiões-dentistas, no âmbito administrativo, as Resoluções do CFO N° 198/2019 e N° 230/2020 enfatizam que procedimentos na orelha não compõem o escopo de procedimentos pertinentes à Odontologia, podendo levar a infrações éticas e consequente processo administrativo. Conclusão: No momento atual, com base nas competências, vedações, direitos e deveres dos cirurgiões-dentistas, pode-se afirmar que a realização do "ear shut" por estes profissionais confronta obrigações de ordem cível, penal e administrativa.

Resposta dos parâmentros do andar após intervenção com dicas auditivas rítmicas em idosos com doença de Parkinson / Response of gait parameters after intervention with rhythmic auditory cues in older people with parkinson's disease

Introdução: os comprometimentos do andar em idosos com doença de Parkinson (DP) estão associados à elevada ocorrência de quedas e à redução dos níveis de independência. O objetivo do estudo foi comparar a resposta dos parâmetros do andar em idosos com doença de Parkinson (DP), durante, imediatamente após e até uma hora após o término de uma sessão de treinamento do andar com e sem dicas auditivas rítmicas, utilizando três ritmos diferentes para o grupo dica (10% abaixo da cadência preferida, cadência preferida e 10% acima) e um ritmo diferente para o grupo controle (velocidade usual de cada participante). Métodos: vinte e nove idosos foram aleatoriamente distribuídos em dois grupos: "controle" e "dica". As sessões de intervenção tiveram 30 minutos de duração e a diferença entre os grupos foi a utilização de dicas auditivas rítmicas oferecidas por um metrônomo no grupo dica. O andar foi avaliado antes, durante e até uma hora após a sessão de intervenção. Resultados: os grupos apresentaram desempenhos similares ao longo das avaliações, com aumento do comprimento do passo e redução da variabilidade da duração do passo. Conclusão: a sessão de intervenção com dicas auditivas rítmicas apresentou efeitos similares aos da sessão de treino sem dica para o andar de idosos com DP.(AU)

Introduction: Gait impairments in older people with Parkinson's disease (PD) are associated with a high occurrence of falls and reduced levels of patients' independence. The objective of the study was to compare the response of gait parameters in older people with Parkinson's disease (PD), during, immediately after, and up to 1h after the end of a single locomotion training session with and without rhythmic auditory cues, using 3 different rhythms for the tip group (10% below the preferred cadence, preferred cadence and 10% above) and 1 different rhythm for the control group (usual speed of each participant). Materials and method: 29 older people were randomly assigned to two groups: Control and "Cue". The intervention sessions lasted 30 minutes and the difference between the groups was the use of rhythmic auditory cues offered by a metro-nome in the Cue group. Gait was assessed before, during, and up to 1 hour after the intervention session. Results: The groups showed similar performances throughout the assessments, with increased step length and reduced step time variability in response to the intervention (compared to the baseline assessment). Conclusion: The intervention session with rhythmic auditory cues had similar effects on gait as the session without cues in older people with PD.(AU)

External Application Characteristics of Roots and Rhizomes of Chinese Herbal Medicines in Chinese Materia Medica / 中国实验方剂学杂志

ObjectiveTo collect and analyze the properties and application characteristics of external use of roots and rhizomes of Chinese herbal medicines in the Chinese Materia Medica（《中华本草》） to provide data references for the research on clinical external use of Chinese medicine， in order to provide data reference for clinical external use of traditional Chinese medicine（TCM）. MethodThe Chinese herbal medicines included in the Chinese Materia Medica were systematically screened. The inclusion criterion was the explicit mention of terms like "root", "rhizome", "root bark", "tuber", "tuberous root", etc. under the "Source" in the Chinese Materia Medica. Information on properties, flavors, meridian tropism, medicinal parts, fresh use, toxicity, efficacies and indications, and dosage of roots and rhizomes of Chinese herbal medicines was collected. The information was then entered into an Excel spreadsheet for statistical analysis. ResultThe Chinese Materia Medica records 2 662 roots and rhizomes of Chinese herbal medicines, of which 1 653 are suitable for external use. The predominant properties and flavors are cool, cold, bitter, pungent, and sweet. These Chinese herbal medicines mainly act on the liver, lung, and spleen meridians. The primary medicinal parts used include root, rhizome, and root bark. More than half of the roots and rhizomes of Chinese herbal medicines can be used in their fresh form. The main efficacies include clearing heat, removing toxins, resolving stasis, dispersing accumulation, resolving blood stasis and stopping bleeding, reducing swelling and alleviating pain, dispelling dampness and relieving pain. The main indications are skin sores, traumatic injuries, and rheumatic diseases. Common external application methods include poultice, decoction for washing, and applying powdered form. Most of these Chinese herbal medicines lack specific dosage guidelines for external use, with an emphasis on using an appropriate amount. ConclusionThe Chinese Materia Medica contains a wide range of roots and rhizomes of Chinese herbal medicines suitable for external use, with definite therapeutic effects, providing a broad perspective for the application of Chinese medicine externally. However, there are still problems such as unclear dosages and limited research. Further studies are necessary to better utilize the advantages of the external use of Chinese medicine.

Renshen Baidusan Combined with Yurui Enema Treats Intestinal Mucosal Injury in Rat Model of Ulcerative Colitis via PI3K/Akt/NF-κB Pathway / 中国实验方剂学杂志

ObjectiveTo explore the mechanisms of internal treatment （Renshen Baidusan）， external treatment （Yurui Enema）， and combination of the two methods in treating intestinal mucosal injury in the rat model of ulcerative colitis （UC） from the changes of phosphatidylinositol-3 kinase （PI3K）/protein kinase B （Akt）/nuclear factor-κB （NF-κB） pathway. MethodFifty SPF-grade SD rats were randomized into blank， model， Renshen Baidusan （15.6 g·kg-1）， Yurui Enema （25 g·kg-1）， and combined treatment （15.6 g·kg-1 Renshen Baidusan + 25 g·kg-1 Yurui Enema） groups （n=10）. The rat model of UC was established in other groups except the blank group by 2，4， 6-trinitrosulfonic acid （TNBS）/ethanol. The rats were administered with corresponding drugs once a day for 14 consecutive days since the 8th day after modeling. The histopathological changes of colon were observed by hematoxylin-eosin （HE） staining. Enzyme-linked immunosorbent assay （ELISA） was employed to measure the levels of tumor necrosis factor （TNF）-α， interferon （IFN）-γ， interleukin （IL）-4， and IL-10 in the colon tissue. The apoptosis of colon epithelial cells was detected by terminal deoxynucleotidyl transferase-mediated nick end labeling （TUNEL）. The location and expression of B-cell lymphoma-2 （Bcl-2）， Bcl-2-associated X protein （Bax）， TNF-α， and IL-6 in the colon tissue were examined by immunohistochemistry. Real-time quantitative fluorescence polymerase chain reaction （Real-time PCR） and Western blot were employed to determine the mRNA and protein levels， respectively， of the proteins in the PI3K/Akt/NF-κB pathway in the colon tissue. ResultIn the model group， HE staining showed a large number of inflammatory cell infiltration in the mucosa and submucosa. Compared with the blank group， the model group showed elevated levels of TNF-α and IFN-γ and lowered levels of IL-4 and IL-10 in the colon tissue， increased apoptosis rate of colon epithelial cells， increased positive expression of Bax， TNF-α， and IL-6， and decreased positive expression of Bcl-2 （P<0.05）. Moreover， the model group showed up-regulated mRNA levels of PI3K， Akt， and NF-κB and protein levels of PI3K， p-PI3K， Akt， p-Akt， p65， p-p65， Bax， and cleaved Caspase-3， increased Bax/Bcl-2 and cleaved Caspase-3/Caspase-3 ratios， and down-regulated protein levels of NF-κB suppressor protein α（IκBα）， Bcl-2， and Caspase-3 in the colon tissue （P<0.05）. Compared with the model group， the internal treatment， the external treatment， and the combination （referred to as the three groups） alleviated the colonic mucosal injury， lowered the levels of TNF-α and IFN-γ and elevated the levels of IL-4 and IL-10 in the colon tissue， decreased the apoptosis rate of colon cells， inhibited the positive expression of Bax， TNF-α， and IL-6， and promoted the positive expression of Bcl-2 （P<0.05）. Furthermore， the combination group down-regulated the mRNA level of PI3K （P<0.05）. The three groups down-regulated the mRNA levels of Akt and NF-κB and the protein levels of p-PI3K， Akt， p-Akt， p65， p-p65， Bax， and cleaved Caspase-3 in the colon tissue， decreased the Bax/Bcl-2 and cleaved Caspase-3/Caspase-3 ratios， and up-regulated the protein levels of IκBα， Bcl-2， and Caspase-3 （P<0.05）. ConclusionRenshen Baidusan， Yurui Enema， and their combination may inhibit the activation of PI3K/Akt/NF-κB signaling pathway and regulate the expression of genes and proteins related to this pathway to achieve anti-inflammatory and anti-apoptotic effects， thus restoring the intestinal mucosal barrier function of UC rats.

Comparison of the efficacy between transperineal ultrasound and endoanal ultrasound in diagnosing obstetrics anal sphincter injury / 中华超声影像学杂志

Objective:To study the agreements between transperineal ultrasound (TPUS) and endoanal ultrasound in assessing obstetrics anal sphincter injury (OASI), and to analyse the diagnostic efficacy of OASI in predicting AI relationship between OASI and anal incontinence (AI).Methods:A total of 217 women were prospectively recruited from the clinic in the Second Xiangya Hospital of Central South University from January 2021 to May 2022. Symptoms of AI were determined using the St Mark′s Incontinence Score (SMIS). TPUS and EAUS were performed by the same operator with the same machine on every participant for detecting OASI: OASI grades 3a, 3b, 3c, and 4 were performed according to the extent of the injuries in the anal sphincter complex. The angle of the defect in the external anal sphincter (EAS) was measured. A "significant EAS defect" was diagnosed as a defect affecting at least 2/3 of the length of the EAS with a defect angle of ≥30° in each slice.Ultrasound findings were compared between the two methods. The diagnostic efficacy of "ultrasound OASI" in predicting AI was analysed by logistic regression.Results:Of 217 women, twenty-eight (12.9%) suffered from AI with SMIS ranging from 5~20(11.9±4.5). On TPUS, 79 (36.4%) cases were suspected of OASI, that was 50 OASI 3a, 13 OASI 3b, and 16 OASI 3c/4. On EAUS, 78 (35.9%) cases were suspected of OASI that was 23 OASI 3a, 22 OASI 3b, 15 OASI 3c, and 18 OASI 4. Twenty-four "significant EAS defects" were diagnosed by TPUS and twenty-eight by EAUS, TPUS had excellent agreement with EAUS (weighted Kappa=0.91, P<0.001). Logistic regression analysis showed that "ultrasound OASI" was associated with AI symptoms. ROC curve analysis showed that the area under the curve (AUC) was 0.92, 0.87, 0.89, 0.92 for TPUS OASI 3b+ , EAUS OASI 3b+ , TPUS "Significant EAS defect" , and EAUS "Significant EAS defect" for predicting AI, respectively. Conclusions:TPUS has good agreement with EAUS in detecting OASI. OASI 3b+ and "significant EAS defect" on TPUS and EAUS had good performance in predicting AI symptoms.
