Funcionalidad del miembro inferior con exposición ósea con el uso de terapia con presión negativa VAC® vs. colgajo de gemelo medial

Objetivo: Comparar dos técnicas de cirugía reconstructiva para lesión en miembro inferior con exposición ósea y, a través de ella, diferenciar que la técnica de VAC® (Vacuum Assisted Closure, cierre asistido con presión negativa) es una alternativa con beneficio de recuperación potencial sin alteraciones significativas que pudieran llevar a un compromiso funcional. Materiales y métodos: Estudio de tipo analítico con corte prospectivo, cuantitativo y longitudinal, en el que se desarrolló la terapia con el uso del sistema de VAC® y de colgajo gemelar medial en todos los pacientes de la Clínica Stella Maris que presentaron heridas traumáticas de miembro inferior con exposición ósea de tercio medio tibial durante el periodo 2019. Resultados: Se evidenció que la medición con la escala funcional de la marcha (FAC, por sus siglas en inglés) fue mejor en los pacientes con la técnica de VAC® (dado que el 50 % tiene grado V) respecto a la técnica de colgajo (50 % en grado IV); las diferencias fueron estadísticamente significativas (p < 0,05). Se apreció que el tiempo de cierre fue mayor en la técnica de VAC® debido al proceso de regeneración progresiva hasta llenar o cubrir la zona completa de la lesión; por otro lado, se evidenció la diferencia de la intensidad del dolor posoperatorio entre las dos técnicas: de moderado a intenso con la técnica de colgajo y leve, en su mayoría, con la técnica de VAC®. Conclusiones: El sistema de aspiración VAC® es eficiente para la cobertura ósea en defectos traumáticos del tercio medio tibial anterior, por lo que constituye una alternativa con potencial beneficio de recuperación sin alteración de estructuras anatómicas, ya que brinda mejores resultados funcionales y menores complicaciones. Es una opción útil que actúa de forma segura porque estimula el cierre de la herida y minimiza las necesidades de un tratamiento quirúrgico.

Objective: To compare two reconstructive surgery techniques for lower limb injury with exposed bone and demonstrate that the VAC® (vacuum-assisted closure) negative pressure wound therapy is an alternative for potential recovery showing no significant changes that could lead to functional compromise. Materials and methods: An analytical, prospective, quantitative and longitudinal study conducted with all the patients of Clínica Stella Maris with traumatic injuries of the lower limb and exposure of the middle third of the tibia treated with the VAC® system and the medial calf flap in 2019. Results: The measurement obtained with the functional ambulation categories (FAC) scale showed better results among the patients treated with the VAC® technique (since 50 % got grade V) than those who underwent the flap technique (50 % got grade IV), being the differences statistically significant (p < 0.05). It was observed that the time to closure was longer with the VAC® technique due to the progressive regeneration process consisting of the complete filling or coverage of the lesion area. On the other hand, the difference in the postoperative pain intensity between the two techniques was evident, being moderate to intense with the flap technique and mild, for the most part, with the VAC® technique. Conclusions: The VAC® suction system is effective for bone coverage in traumatic defects of the anterior middle third of the tibia. It is an alternative for potential recovery that does not change the anatomical structures because it provides better functional results and fewer complications. It is a useful and safe option that stimulates wound closure and minimizes the need for surgical treatment.

A Study of Clinico-social Profile of Animal Bite Patients Attending the Antirabies Clinic of BRD Medical College, Gorakhpur

Background: Rabies is one of zoonotic viral disease, estimated to cause 59000 human deaths annually in over 150 countries, of which 20,000 are from India alone; about 40% of which are in children under the age of 15. Rabies though 100% fatal is preventable with post-exposure prophylaxis which includes wound washing, anti-rabies vaccination and rabies immunoglobulin. Objective: To describe the clinico-social profile of animal bite patients attending the anti-rabies clinic of BRD Medical College, Gorakhpur. Methodology: A cross-sectional study was conducted in the anti-rabies clinic of Nehru hospital, BRD Medical College, Gorakhpur from January 2022 to May 2022. Study participants were interviewed by using a pre-phrased, pre-designed and pre-tested questionnaire. Data regarding socio-demographic and clinical profile of the study participants following animal bite exposure was collected. Results: The total number of animal bite victims were 250, in which majority of them were males (76.77%) and highest percentage was of adult population (20-59 years). Maximum number of victims were from rural area (78.70%). 19.35% were working and 39.35% were students. 77.43% were category III bites and in 50.96% cases lower limb was the site of bite and dogs were responsible for 89.67% of the bites. 60.64% victims did not wash the wound properly before reaching the anti-rabies clinic. Conclusion: This study concludes that as majority of the animal bite victims were students and majority of victims were unaware about the importance of wound care, therefore a step can be taken to create awareness in various schools.

OBJECTIVE@#To investigate the clinical effect of aconite-isolated moxibustion at Yongquan (KI 1) combined with rivaroxaban for lower extremity venous thrombosis after total knee arthroplasty and the influence on hypercoagulation.@*METHODS@#Seventy-three patients of knee osteoarthritis with lower extremity venous thrombosis after total knee arthroplasty (KOA) were randomly divided into an observation group (37 cases, 2 cases dropped off) and a control group (36 cases, 1 case dropped off). The patients in the control group took orally rivaroxaban tablets, 10 mg a time, once a day. On the basis of the treatment as the control group, the aconite-isolated moxibustion was applied to Yongquan (KI 1) for the patients of the observation group, once daily and 3 moxa cones were used in each treatment. The duration of treatment was 14 days in both groups. Before treatment and 14 days into treatment, the ultrasonic B test was adopted to determine the conditions of lower extremity venous thrombosis in the two groups. Before treatment, 7 and 14 days into treatment, the coagulation indexes (platelet [PLT], prothrombin time [PT], activated partial prothrombin time [APTT], fibrinogen [Fib] and D-dimer[D-D]), the blood flow velocity of the deep femoral vein and the circumference of the affected side were compared between the two groups separately, and the clinical effect was evaluated.@*RESULTS@#Fourteen days into treatment, the venous thrombosis of the lower extremity was relieved in both groups (P<0.05), and that of the observation group was better than the control group (P<0.05). Seven days into treatment, the blood flow velocity of the deep femoral vein was increased compared with that before treatment in the observation group (P<0.05), and the blood flow rate in the observation group was higher than that in the control group (P<0.05). Fourteen days into treatment, PT, APTT and the blood flow velocity of the deep femoral vein were increased in the two groups compared with those before treatment (P<0.05); and PLT, Fib, D-D and the circumference of the limb (knee joint, 10 cm above the patella and 10 cm below the patella) were all reduced in the two groups (P<0.05). Compared with the control group 14 days into treatment, the blood flow velocity of the deep femoral vein was higher (P<0.05), PLT, Fib, D-D and the circumference of the limb (knee joint, 10 cm above the patella and 10 cm below the patella) were all lower in the observation group (P<0.05). The total effective rate was 97.1% (34/35) in the observation group, higher than 85.7% (30/35) in the control group (P<0.05).@*CONCLUSION@#Aconite-isolated moxibustion at Yongquan (KI 1) combined with rivaroxaban can effectively treat lower extremity venous thrombosis after total knee arthroplasty, relieve hypercoagulation, accelerate the blood flow velocity and alleviate swelling of the lower extremity in the patients with knee osteoarthritis.

Lower limb balance characteristics during tai chi chuan / Características de equilíbrio dos membros inferiores durante o tai chi chuan / Características del equilibrio de los miembros inferiores durante el tai chi chuan

ABSTRACT Introduction: Tai chi chuan training claims to not only promote the circulation of internal energy in the body to achieve a preventive and healing effect of diseases, but also to improve static and dynamic body balance. While the former claims are not validable, the question about the effectiveness of improving balance remains valid. Objective: Verify the characteristics of lower limb balance during tai chi chuan practice. Methods: Selected volunteers underwent a bioelectricity testing system via noninvasive surface electromyography to evaluate muscle activity during the exercises. The results were collected, cataloged and statistically work on corresponding graphs according to different content of literature research for objective analysis. Results: The variation of the displacement of the center of gravity was controlled within 0.1M, the most unstable time of the center of gravity was about 0.65s before the start of balance. In temporal terms, it is found that the order of discharge of each muscle tested in the vertical balance and unilateral support was as follows: the tibialis anterior muscle discharges first, the rectus femoris and biceps femoris second, finally gastrocnemius, gluteus medius and gluteus maximus joint discharge almost at the same time. Conclusion: Some benefit is perceived in the validity of improving lateral balance velocity, shortening the action completion time, and improving balance stability, improving the quality of action in practitioners of this exercise modality. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

RESUMO Introdução: O treinamento do tai chi chuan alega não só promover a circulação de energia interna no corpo para alcançar um efeito preventivo e curador de doenças, mas também aprimorar o equilíbrio estático e dinâmico corporal. Enquanto as primeiras afirmações não são validáveis, o questionamento sobre a eficácia no aprimoramento do equilíbrio permanece válido. Objetivo: Verificar as características do equilíbrio nos membros inferiores durante a prática do tai chi chuan. Métodos: Voluntários selecionados passaram por um sistema de testes com bioeletricidade via eletromiografia superficial não invasiva para avaliar a atividade muscular durante os exercícios. Os resultados foram coletados, catalogados e estatisticamente trabalhos sobre gráficos correspondentes, de acordo com diferentes conteúdos de pesquisa literária, para análise objetiva. Resultados: A variação do deslocamento do centro gravitacional foi controlada dentro de 0,1M, o tempo mais instável do centro de gravidade foi cerca de 0,65s antes do início do equilíbrio. Em termos temporais, constata-se que a ordem de descarga de cada músculo testado no equilíbrio vertical e apoio unilateral foi a seguinte: o músculo tibial anterior descarrega primeiro, o reto femoral e bíceps femoral em segundo lugar, finalmente conjunto gastrocnêmico, glúteos médios e glúteo máximo descarregam quase ao mesmo tempo. Conclusão: Percebe-se algum benefício na validade de aprimorar a velocidade de balanço lateral, encurtar o tempo de conclusão da ação e melhorar a estabilidade do equilíbrio, melhorando a qualidade da ação em praticantes dessa modalidade de exercício.
