Manejo terapéutico de actualidad de heridas complejas del tercio distal de la pierna en el Hospital de Trauma (Prof. Manuel Giagni) y en la Unidad de Cirugía Plástica de la Facultad de Ciencias Médicas - UNA / Current therapeutic management of complex wounds of the distal third of the leg in the Trauma Hospital (Prof. Manuel Giagni) and in the Plastic Surgery Unit of the Faculty of Medical Sciences - UNA

Introducción: La herida es una pérdida de continuidad de la piel o mucosa producida por algún agente físico o químico. Una herida es "compleja" cuando por su extensión, localización, profundidad o exposición de elementos nobles, necesita para su curación una terapéutica especial. Este es el caso de heridas con compromiso tisular que afecta a estructuras como músculos, fascias, tendones, huesos, vasos sanguíneos, nervios o las lesiones de lenta evolución como úlceras o escaras. Objetivos: Determinar el método de reconstrucción más utilizado en el manejo terapéutico de las heridas complejas del tercio distal de la pierna en los pacientes atendidos en el Hospital de Trauma y en la Unidad de Cirugía Plástica de la FCM - UNA. Materiales y métodos: Estudio de diseño observacional, tipo de estudio descriptivo y retrospectivo. Fueron incluidos pacientes de ambos sexos, mayores de edad, con heridas complejas en el tercio distal de la pierna, atendidos en el Hospital de Trauma y en la Unidad de Cirugía Plástica de la FCM - UNA, durante el periodo 2010 al 2019. Resultados: Se incluyó a 112 pacientes de los cuales el 80,36 % fue hombres y el 19,64 % mujeres. Las edades estaban comprendidas entre los 18 y los 73 años y una media de 33,8 ± 14 años. La edad más frecuente fue 18 años. La mediana de edad es de 30 años, lo que implica que la mitad de la muestra tuvo por lo menos dicha edad. En cuanto a la procedencia, el 41,07 % era del interior, el 30,36 % del departamento Central y el 28,57 % restante de Asunción. En cuanto al mecanismo de la lesión, se puede observar que el mecanismo más frecuente fue el accidente de tráfico, seguido por caída de altura, en un gran porcentaje. En cuanto a la evolución y complicaciones se puede ver que 92 individuos, o sea 82 % de los pacientes no tuvo ninguna evolución negativa o complicaciones. Lo más común fue la infección con 1,9% de prevalencia, la pérdida parcial del colgajo o piel representan el 2,4%, dehiscencia de la sutura el 0,9 %, hematoma 0,6 % y pérdida total del colgajo 0,54 %. En cuanto al tratamiento aplicado, se debe tener en cuenta que los pacientes pudieron haber recibido más de un tratamiento por lo que el tamaño de la muestra se refiere a las visitas. El tratamiento más frecuente fue el colgajo sural con 28,57%, tutor externo con el 20,19%, injerto de piel 16,46%, toillete 12,73% y colgajo fascio - cutáneo en 6,21%. Conclusión: La gran mayoría de los casos tratados corresponde a algún tipo de accidente de tránsito. Se necesita de un equipo multidisciplinario: ortopedistas, cirujanos plásticos, cirujanos vasculares, fisioterapeutas, etc. en trabajo coordinado para tratar estas graves lesiones de forma a obtener resultados favorables. Para la cobertura de la pierna traumatizada, con exposición ósea, recurrimos a los colgajos musculares, en el 1/3 proximal el gemelo, en el 1/3 medio el sóleo. Para la cobertura del 1/3 distal de la pierna utilizamos el colgajo neuro-veno-fascio-cutáneo (sural) a pedículo distal.

Introduction: The wound is a loss of continuity of the skin or mucosa produced by some physical or chemical agent. A wound is "complex" when due to its extension, location, depth, exposure of noble elements, it requires special therapy to heal. This is the case of wounds with tissue involvement that affects structures such as muscles, fascia, tendons, bones, blood vessels, nerves, or slowly evolving lesions such as ulcers or bedsores. Objectives: Determine the reconstruction method most used in the therapeutic management of complex wounds of the distal third of the leg in patients treated at the Trauma Hospital and the Plastic Surgery Unit of the FCM - UNA. Materials and methods: Observational, descriptive, and temporally retrospective study. Patients of both sexes, of legal age, with complex wounds in the distal third of the leg, treated at the Trauma Hospital and in the Plastic Surgery Unit of the FCM - UNA, during the period 2010 to 2019, were included. Results: 112 patients were included, of which 80.36% are men and 19.64% are women. The ages range from 18 to 73 years and an average of 33.8 ± 14 years. The most common age was 18 years. The median age is 30 years, which implies that half of the sample is at least that age. Regarding origin, 41.07% are from the interior, 30.36% from the Central department and the remaining 28.57% from Asunción. Regarding the mechanism of injury, the most frequent mechanism was a traffic accident, followed by a fall from a height, in a large percentage. Regarding the evolution and complications, 92, that is, 82% of the patients do not have any negative evolution or complications. The most common was infection with 1.9%, partial loss of the flap or skin represented 2.4%, suture dehiscence with 0.9%, hematoma 0.6%, and total loss of the flap 0.54. %. Regarding the treatment applied, it must be considered that patients may have received more than one treatment, so the sample size refers to visits. The most frequent treatment was the sural flap with 28.57%, external tutor with 20.19%, skin graft 16.46%, toilette 12.73% and fasciocutaneous flap in 6.21%. Conclusion: Most cases treated correspond to some type of traffic accident. A multidisciplinary team is needed: orthopedists, plastic surgeons, vascular surgeons, physiotherapists, etc. in coordinated work to treat these serious injuries to obtain favorable results. To cover the traumatized leg, with bone exposure, we resort to muscle flaps. In the proximal 1/3, the gastrocnemius. In the middle 1/3, the soleus. To cover the distal 1/3 of the leg we used the neuro-veno-fascio-cutaneous (sural) flap to the distal pedicle.

Alertamientos y movimientos periódicos de las piernas durante las etapas de sueño y deterioro cognitivo leve en adultos mayores. Estudio preliminar / Arousals and periodic leg movements during sleep stages and mild cognitive impairment in older adults: a preliminary study

RESUMEN La fragmentación del sueño puede asociarse con distintas enfermedades, entre ellas, la demencia. En este sentido, la fragmentación de sueño, indicada por el índice de alertamientos y/o movimientos periódicos de las piernas (MPP), podría ser un marcador temprano de deterioro cognitivo leve (DCL), un síndrome precursor de la demencia. El objetivo del presente estudio fue medir el índice de prevalencia de los alertamientos y de los MPP durante el sueño en un grupo control y un grupo con DCL, así como determinar si hay diferencia entre los grupos en ambos índices y establecer si existe una correlación entre los dos fenómenos. En 9 participantes (3 mujeres controles y 3 mujeres con DCL; y 3 hombres con DCL) (edad: 69.1 ± 5; años de educación: 8 ± 2) se registró una noche de polisomnografía. Se obtuvieron los índices por hora de alertamientos y para cada etapa de sueño, así como los MPP globales y por hora; además se realizaron análisis entre y dentro de cada grupo. Se encontró una correlación positiva y un mayor número de MPP que de alertamientos durante toda la noche en los participantes con DCL. Conocer la prevalencia y asociación de ambos fenómenos contribuye en la formulación de una evaluación más cuidadosa y profunda de los adultos mayores en riesgo de desarrollar DCL y/o demencia.

ABSTRACT Sleep fragmentation may be associated with several diseases, including dementia. In this sense, sleep fragmentation, indicated by the rates of arousals and/or periodic leg movements (PLM), could be an early marker of Mild Cognitive Impairment (MCI), a syndromic stage prior to dementia. Therefore, the objective of this study was to compare the index of PLM with that of arousals and correlate both indexes in people with MCI and without MCI during all sleep stages. In 9 participants (3 control women and 3 women with MCI; and 3 men with MCI) (ages: 69.1 ± 5; years of education: 8 ± 2), one night of polysomnography was performed. Hourly rates of arousals and PLM were scored from each sleep stage. Analyses were performed within and between PLM and arousals for each group. Significant differences and a positive correlation were found between the arousal and the PLM rates for the group with MCI during the whole night. Knowledge of the prevalence and the association of both phenomena may contribute to a more careful and thorough evaluation of older adults at risk of developing MCI and/or dementia.

Objetivo: analizar el costo-efectividad y calcular la relación costoefectividad incremental del tratamiento multicapa compresivo con respecto al inelástico (bota de Unna y estiramiento corto) según la literatura actual. Método: estudio cuantitativo de costo-efectividad a través de un modelo con ayuda del software TreeAge® para la elaboración del árbol de decisión. Los supuestos anunciados se obtuvieron mediante el uso de datos secundarios de la literatura para estimar el costo y la efectividad de los parámetros asumidos. Para ello, se realizó una revisión sistemática de la literatura con metaanálisis. Resultados: el árbol de decisión, después del Roll Back, mostró que la terapia multicapa prevaleció sobre las alternativas en el caso base, presentó un costo intermedio por aplicación, pero obtuvo la mayor efectividad. El gráfico del análisis de costo-efectividad también demostró que había un dominio extendido de la bota de Unna sobre el vendaje de estiramiento corto. El análisis de sensibilidad reveló que el vendaje multicapa sigue siendo la alternativa con mayor costoefectividad, dentro del umbral de disposición a pagar. Conclusión: la alternativa con mayor costo-efectividad fue el vendaje multicapa, considerado estándar de oro en la literatura. La segunda alternativa con mayor costo-efectividad fue la bota de Unna, la terapia más utilizada en Brasil.

Objective: to analyze the cost-effectiveness and calculate the incremental cost-effectiveness ratio of multilayer compressive treatment in relation to inelastic (Unna boot and short stretch) therapy according to the current literature. Method: quantitative study about cost-effectiveness through modeling with the aid of TreeAge® software for construction of the decision tree. The anticipated assumptions were obtained by using secondary literature data to estimate the cost and effectiveness of the assumed parameters. A systematic literature review with meta-analysis was performed for this end. Results: the decision tree after Roll Back showed that the multilayer therapy dominated the alternatives in the base case, representing an intermediate cost per application, although with the highest effectiveness. The cost-effectiveness analysis graph also showed extended dominance of the Unna boot in relation to the short stretch bandage. The sensitivity analysis showed that multilayer bandage remains a more cost-effective alternative, within the threshold of willingness to pay. Conclusion: the most cost-effective alternative was multilayer bandage, considered the gold standard in the literature. The second most cost-effective alternative was the Unna boot, the most used therapy in Brazil.

A Review of the Analysis of Ground Reaction Force among Adults with Lower Limb Problems (Tinjauan Analisis Daya Tindak Balas Tanah di Kalangan Orang Dewasa dengan Masalah Anggota Bawah) / Jurnal Sains Kesihatan Malaysia

@#The ground reaction force (GRF) is the equal opposing load transfer from the body to the ground, also called vertical load transfer. The GRF would produce stress waves transmitted toward the lower extremities during the heel strike of a gait cycle. Too much force imposed on the lower extremities for an extended period will cause harmful effects such as injuries or alterations in gait. This article presents a review of the literature on GRF analysis among adults with lower limb problems where comparisons between healthy and unhealthy subjects were analyzed, focusing on the compensation in each lower limb. A literature search of published articles in Science Direct and PubMed databases from August 2015 to March 2021 was analyzed. The keywords used for the search were (plantar force OR vertical load transfer OR ground reaction force) AND (lower limb OR lower extremities OR leg OR foot) AND (impairment OR problem OR injury). The literature search identified 22 relevant studies which were screened independently by two reviewers. Lower limb problems such as unilateral transfemoral amputation, unilateral transtibial amputation, patellofemoral pain, anterior cruciate ligament injury, knee arthroplasty, knee osteoarthritis, diabetic foot, total hip replacement, pronated foot proved to alter the GRF significantly. Patients used to shift their weight on the opposite leg as compensation, which acts as a pain-free mechanism. This paper has provided sufficient understanding regarding GRF among adults with lower limb problems. The knowledge concerning compensation may help physical therapists implement the appropriate intervention for patients with lower limb problems.

Pseudo-orthostatic tremor as a manifestation of vitamin B12 deficiency: A case report

@#Vitamin B12 deficiency has long been known to present with various neurological manifestations, but only rarely presents as movement disorders, especially in adults. We present the case of a 30-year-old vegan male presenting with tremors on both legs when standing which was relieved by vitamin B12 supplementation. To the best of our knowledge, this is the first documented case of slow orthostatic tremor or pseudo-orthostatic tremor caused by vitamin B12 deficiency.

ObjectiveTo design a simple leg-sliding rehabilitation equipment for patients with lower limb dysfunction who need to exercise their leg muscles in bed at the early stage of rehabilitation. MethodsThe mechanism scheme was designed using the crank slider transmission system. The kinematic model was established and the structural dimensions were determined according to the human joint mobility, analysis and verification were then implemented; and the strutural strength of the machanism was verified, and based on the analysis, a protype was built to verify the feasibility of proposed scheme. ResultsThe range of joint activities of the proposed mechanism was in line with the normal human joint activities, the structural strength met the requirements, the prototype operated smoothly, and the actual running speed was basically consistent with the theoretical planning speed. ConclusionThis design could meet the needs of rehabilitation training for bedridden patients with lower limb dysfunction at the early stage of rehabilitation. It has the advantages of small size and light weight, which provides reference value for promoting the development of miniaturized and lightweight lower extremity rehabilitation equipment.

Repair of soft tissue defect of the middle and lower leg with island flap / 中华医学美学美容杂志

Objective:To investigate the methods and effect of wound repair after partial skin and soft tissue necrosis of middle and lower leg fracture surgery.Methods:Three kinds of island flaps were used to repair the wound after skin and soft tissue necrosis of middle and lower leg fracture surgery in 22 patients. Nine patients were repaired with sural neurotrophic fascial flaps, 7 patients with posterior tibial artery perforator flaps, and 6 patients with peroneal artery perforator flaps. The area of wound defect was 3.0 cm×3.8 cm to 12.0 cm×9.0 cm. The donor area was directly sutured, or free skin grafted.Results:All patients were the cases after partial skin and soft tissue necrosis of middle and lower leg fracture surgery, with bone, internal fixation plate or tendon exposed. The skin flaps in 21 patients were survived, and the wound healed by first intention. The sural neurotrophic fascial flap necrosis in one patient was due to hematoma and entrapment in vascular pedicle. After 5 to 24 months (mean 9 months) follow-up, texture of flaps was good, no ulcer occured, and outlook of the repaired wound was satisfied. The sutured wound of donor site and skin-grafting had healed by first stage intention.Conclusions:Repair with island flap is an ideal way to the defect wound after skin and soft tissue necrosis of middle and lower leg fracture surgery.

Clinical and electrophysiological study of lower limb split signs in amyotrophic lateral sclerosis / 中华神经科杂志

Objective:To investigate the association between split foot and electrophysiology in patients with amyotrophic lateral sclerosis (ALS).Methods:The clinically definite or clinically probable ALS patients hospitalized in the Department of Neurology, the First Medical Center of Chinese People′s Liberation Army General Hospital from April 2021 to December 2022 were prospectively collected. From April 2021 to December 2022, patients who visited the Chinese People′s Liberation Army General Hospital for other reasons without abnormal electrophysiological examination were collected as the control group. The incidence of split leg [the limb whose modified Medical Research Council Muscle Strength Scale (mMRC) score of ankle dorsiflexors was lower than that of ankle plantarflexors] in ALS patients was calculated, and the incidence of split foot (the limb whose mMRC score of hallux dorsiflexors was lower than that of hallux plantarflexors) in ALS patients was calculated. The amplitude of compound muscle action potential (CMAP) of common peroneal nerve and tibial nerve was detected to observe the involvement of motor neurons innervating ankle dorsiflexors and ankle plantarflexors. The characteristics of split leg and split foot in ALS patients were analyzed from the perspective of muscle strength, and the characteristics of split foot in ALS patients were analyzed from the perspective of electrophysiology. Receiver operating characteristic (ROC) curve was used to analyze the sensitivity and specificity of peroneal nerve/tibial nerve CMAP amplitude ratio in distinguishing ALS patients from controls.Results:A total of 101 ALS patients with lower limb involvement and 110 controls with normal lower limb muscle strength were collected. Among the 101 ALS patients with lower limb involvement, strength of ankle plantarflexors was greater than that of ankle dorsiflexors in 35.64% (36/101) patients, strength of ankle dorsiflexors was greater than that of ankle plantarflexors in 5.94% (6/101) patients, and strength of ankle plantarflexors and ankle dorsiflexors was equal in 58.42% (59/101) patients. Strength of hallux dorsiflexors was lower than that of hallux plantarflexors in 53.47% (54/101) patients, strength of hallux dorsiflexors was greater than that of hallux plantarflexors in 1.98% (2/101) patients, and the strength of hallux dorsiflexors and hallux plantarflexors was equal in 44.55% (45/101) patients. The incidence of split leg was negatively correlated with age ( OR=0.25, 95% CI 0.16-0.40, P<0.05), course of disease ( OR=0.52, 95% CI 0.38-0.80 P<0.05) and ALS functional revised scores ( OR=0.29, 95% CI 0.12-0.67, P<0.05). The incidence of split foot was negatively correlated with the onset time of lower limb symptoms ( OR=0.96, 95% CI 0.93-0.99, P<0.05). Compared with the control group, the differences of the decrease of CMAP amplitude in the common peroneal nerve and tibial nerve [the common peroneal nerve (6.45±2.56) mV vs (3.63±1.83) mV, tibial nerve (12.87±4.72) mV vs (9.18±6.22) mV] were statistically significant ( t=-4.65, t=-3.44, both P<0.001) and the differences of the peroneal nerve/tibial nerve CMAP amplitude ratio (0.54±0.24 vs 0.36±0.18) decrease was statistically significant ( t=-4.31, P<0.001) in patients with split foot. ROC curve analysis showed that the area under the ROC curve of CMAP amplitude ratio of common peroneal nerve/tibial nerve in ALS patients with split foot was 0.70, indicating that the accuracy of CMAP amplitude of common peroneal nerve/tibial nerve in distinguishing ALS patients from controls was low. Conclusions:In ALS patients with lower limb involvement, strength of ankle dorsiflexors is weaker than that of ankle plantarflexors, and strength of hallux dorsiflexors is weaker than that of hallux plantarflexors. At the diagnostic level, the CMAP amplitude ratio of common peroneal nerve/tibial nerve in ALS patients with split foot has a lower accuracy in the diagnosis of ALS.

Analysis of misdiagnosed cases of neck, shoulder, waist and leg pain caused by bone metastases and early warning measures / 中国基层医药

Objective:To investigate the cause of misdiagnosis of neck, shoulder, waist, and leg pain caused by bone metastases and to improve the outpatient diagnosis rate.Methods:Five misdiagnosed cases of bone metastases who were admitted to the Traditional Chinese Medicine Department of Orthopedics and Traumatology, School of Traditional Chinese Medicine, Southern Medical University from January 2019 to July 2020 were included in this study. Their clinical manifestations, diagnosis results (outside hospital diagnosis and outpatient diagnosis), and imaging manifestations were retrospectively analyzed.Results:Five cases of bone metastases were misdiagnosed to have cervical spondylosis, lumbar disc herniation, femoral head necrosis, femoral shaft fracture, and ankle sprain. Accelerated red blood cell sedimentation rate and increased C-reactive protein level were found in all five cases. Bone metastases were confirmed by X-ray, CT, and MRI examination results. All of them had warning signs for bone metastasis: age > 50 years, history of a tumor, unexplained weight loss, general malaise, neck, shoulder, waist, and leg pain without an obvious cause, sudden worsening of pain, night pain, resting pain, pain on direct palpation, no obvious improvements in these symptoms after symptomatic treatment for 1 month, disease development not conforming to the general law of cervical spondylosis, lumbar disc herniation, femoral head necrosis, femoral shaft fracture, and ankle sprain, increases in red blood cell sedimentation rate, C-reactive protein, and alkaline phosphatase levels, which are not consistent with the symptoms of cervical spondylosis, lumbar disc herniation, femoral head necrosis, femoral shaft fracture, and ankle sprain, and slight external force leading to fractures.Conclusion:Further tests and imaging examinations should be performed according to warning signs. Clinical schemes of malignant bone tumors suitable for general practitioners can easily, economically, and effectively identify malignant bone tumors.

Metal ion release according to leg length discrepancy in ceramic-on-metal hip arthroplasty / Liberação de íons metálicos segundo discrepância no comprimento da perna após artroplastia metal-cerâmica total de quadril

ABSTRACT Objective The ceramic-on-metal (CoM) bearing has the theoretical advantages over ceramic-on-ceramic (CoC) and metal-on-metal bearings. This study aimed to analyze factors affecting the metal ion release of CoM bearings and compare clinical performance with CoC bearings. Methods The 147 patients were divided into 96 patients in group 1 (CoM group) and 51 patients in group 2 (CoC group). Additionally, within group1, 48 patients and 30 patients were sub-categorized into group 1-A with leg length discrepancy (LLD) less than 1cm and group 1-B greater than 1 cm. The level of serum metal ions, functional scores and plain radiographs were obtained for the analysis. Results The level of cobalt (Co) 2-years after surgery and chromium (Cr) 1-year after surgery showed significantly higher in the group1 than the group2. LLD indicated statistically significant positive correlation between serum metal ion levels among CoM bearing THAs. In comparison of the average metal ions level changes, group 1-B showed higher level of metal ion than group 1-A. Conclusion In patients underwent THA with CoM bearings, large LLD have a higher risk of complications associated to metal ions. Therefore, it is critical to reduce the LLD to 1 cm or less in using CoM bearing. Level of Evidence III; Case Control Study.

Anthropometric profile of leg length inequality and its impact on gait / Perfil antropométrico de la desigualdad en la longitud de las piernas y su impacto en la marcha

SUMMARY: Leg length inequality (LLI) affects gait - primarily pelvic and torso movements. LLI is present in around 40-70 % of the healthy population. Due to LLI's significant impact on the body, as well as the possible occurrence of a variety of associated health problems, the aim of this research is to determine whether there is a significant difference in pelvic movement in all three planes, depending on the degree of LLI. This study was conducted on a sample of 30 healthy subjects. The functional length of lower limbs was measured. When LLI was calculated, kinematic measures were taken of pelvic and lower limb movements during gait using 3D cameras and ©Vicon Motion Systems Ltd. UK. The obtained data on kinematic pelvic movement in all three planes during gait were compared with the reference values. The results show that there is no statistically significant difference in pelvic movement about the axes x, y, and z in cases of LLI of up to 18mm (p>0,05). There is a statistically highly significant positive correlation between the difference in functional leg length (r=0,575; p=0,008) and femur length (r=0,525; p=0,015) on one hand, and the difference in pelvic movement about the axis x on the other, compared to the reference values. In a healthy population with LLI from 0 to 18 mm, gait remains unaffected and an increase in LLI predominantly affects pelvic movement about the horizontal axis (x) - pelvic tilt, which exponentially increases with an increase in femur length discrepancy.

La diferencia en la longitud de las piernas (LLI, por sus siglas en inglés) afecta la marcha, principalmente los movimientos pélvicos y del dorso. La LLI está presente en alrededor del 40-70 % de la población sana. Debido al importante impacto de LLI en el cuerpo, así como a la posible aparición de una variedad de problemas de salud asociados, el objetivo de esta investigación fue determinar si existe una diferencia significativa en el movimiento pélvico en los tres planos, dependiendo del grado de LLI. Este estudio se realizó en una muestra de 30 sujetos sanos. Se midió la longitud funcional de los miembros inferiores. Cuando se calculó el LLI, se tomaron medidas cinemáticas de los movimientos pélvicos y de los miembros inferiores durante la marcha utilizando cámaras 3D y ©Vicon Motion Systems Ltd. UK. Los datos obtenidos sobre el movimiento pélvico cinemático en los tres planos durante la marcha se compararon con los valores de referencia. Los resultados mostraron que no existe diferencia estadísticamente significativa en el movimiento pélvico sobre los ejes x, y, y z en casos de LLI de hasta 18 mm (p>0,05). Existe una correlación positiva estadísticamente muy significativa entre la diferencia en la longitud funcional de la pierna (r=0,575; p=0,008) y la longitud del fémur (r=0,525; p=0,015), y la diferencia en el movimiento pélvico sobre el eje x por otro, en comparación con los valores de referencia. En una población sana con LLI de 0 a 18 mm, la marcha no se ve afectada y un aumento en LLI afecta predominantemente el movimiento pélvico sobre el eje horizontal (x) - inclinación pélvica, que aumenta exponencialmente con un aumento en la discrepancia de longitud del fémur.

Effect of varying dietary crude protein and metabolizable energy levels on leg abnormalities and performance in broiler chickens

Background: Nutrient restriction is a common strategy to prevent metabolic disorders in fast growing broiler chickens, but limited information is available regarding the impact of diets with low protein and energy on leg abnormalities Objective: Two experiments were conducted to evaluate the effect of varying crude protein (CP) and metabolizable energy (ME) levels on gastrocnemius tendon (GTeBS) and tibia breaking strength (TiBS), gait score (GS) and valgus/varus angulation (VAng). Methods: In Experiment 1, eight-d-old Ross 308 broilers (n=90) were randomly assigned into three treatments: 13/2,900 (13% CP and 2,900 kcal ME kg-1 of diet), 17/3,000 (17% CP and 3,000 kcal ME kg-1 of diet), and 21/3,025 or control (21% CP and 3,025 kcal ME kg-1 of diet). In Experiment 2, six-d-old Ross 308 chickens (n=192) were randomly distributed into two treatments: 16/3,000; 16% CP and 3,000 kcal ME kg-1 of diet and 21/3,000 or control; 21% CP and 3,000 kcal ME kg-1 of diet. In both experiments data were analyzed as one-way ANOVA. Results: In Experiment 1, broilers in the 17/3,000 and control treatments had similar (p>0.05) GTeBS (202 and 224 N, respectively), and TiBS (338 and 332 N, respectively). Birds in the 13/2,900 treatment showed higher GS (lower walking ability; 80% of birds with score >3), and greater VAng (53% of birds with score >2) than broilers in the control treatment (0% of birds with GS score >3 and 0% of birds with VAng score >2). Experiment 2, broilers in the 16/3,000 showed similar VAng, GS and TiBS than birds in the control treatment. However, birds in the 16/3,000 treatment showed lower (-26%) GTeBS than birds in the control treatment (p<0.05). Conclusions: Feeding broilers with 16% CP and 3,000 kcal ME kg-1 of diet did not affect tibia breaking strength, gait score and valgus/varus angulation. A diet containing 16% CP or less and 2,900-3,000 kcal ME kg-1 reduces tendon and tibia breaking strength.

Antecedentes: La restricción de nutrientes es una estrategia común para prevenir trastornos metabólicos en pollos de engorde, sin embargo, se dispone de información limitada sobre el impacto de las dietas bajas en proteína y energía en las anomalías de piernas. Objetivo: Se llevaron a cabo dos experimentos para evaluar el efecto de niveles variables de proteína cruda (PC) y energía metabolizable (EM) en la fuerza de rotura del tendón del gastrocnemio (GTeBS) y tibia (TiBS), la evaluación de marcha (GS) y la angulación en valgus/varus (VAng). Métodos: En el Experimento 1, pollos de engorde Ross 308 de ocho días de edad (n = 90) se asignaron al azar en tres tratamientos: 13/2.900; 13% PC y 2.900 kcal ME kg-1 de dieta, 17/3.000; 17% PC y 3.000 kcal ME kg-1 de dieta y 21/3.025 o control; 21% PC y 3.025 kcal ME kg-1 de dieta. En el Experimento 2, pollos Ross 308 de seis días de edad (n = 192) se distribuyeron aleatoriamente en dos tratamientos: 16/3.000; 16% PC y 3.000 kcal ME kg-1 de dieta y 21/3.000 o control; 21% PC y 3.000 kcal ME kg-1 de dieta. En ambos experimentos los datos se analizaron como ANOVA de una vía. Resultados: En el Experimento 1, los pollos de los tratamientos 17/3.000 y control tuvieron GTeBS (202 y 224 N, respectivamente) y TiBS (338 y 332 N, respectivamente) similares (p>0,05). Las aves del tratamiento 13/2.900 mostraron mayor GS (menor capacidad para caminar; 80% de las aves con puntaje >3) y mayor VAng (53% de las aves con puntaje >2) que los pollos del tratamiento control (0% de aves con un puntaje GS >3 y 0% de aves con un puntaje VAng >2). En el Experimento 2, los pollos del 16/3.000 mostraron VAng, GS y TiBS similares a los de las aves del tratamiento control. Sin embargo, las aves del tratamiento 16/3.000 mostraron menor (-26%) GTeBS que las aves control (p<0,05). Conclusiones: La alimentación de pollos de engorde con 16% PC y 3.000 kcal EM kg-1 de dieta no afecta la resistencia a la ruptura de la tibia, la marcha y la angulación valgus/varus. La dieta formulada con 16% de PC o menos y 2.900-3.000 kcal de EM kg-1 reduce la resistencia a la ruptura del tendón y de la tibia.

Antecedentes: A restrição de nutrientes é uma estratégia comum para prevenir distúrbios metabólicos em frangos de corte, no entanto, há informações limitadas disponíveis sobre o impacto de dietas de baixa proteína e baixa energia nas anormalidades de pernas destas aves. Objetivo: Dois experimentos foram realizados para avaliar o efeito de diferentes níveis de proteína bruta (PB) e energia metabolizável (EM) em força de ruptura do tendão do músculo gastrocnêmio (GTeBS), forca de ruptura da tíbia (TiBS), gait score (GS) e angulação em valgus/varus (VAng). Métodos: Experimento 1, foram utilizados 308 frangos de corte machos da linhagem Ross com oito dias de idade (n = 90) distribuidos aleatoriamente em três tratamentos: dieta controle com 21% PB e 3.025 kcal EM kg-1 13/2.900; dieta con 13% PB e 2.900 kcal EM kg-1, y 17% PB e 3.000 kcal EM kg-1 . Experimento 2, foram utilizados 308 frangos de corte da linhagem Ross com seis dias de idade (n = 192) distribuídos aleatoriamente em dois tratamentos: dieta controle con 21% PB e 3.000 kcal EM kg-1 e dieta com 16% PB e 3.000 kcal EM kg-1 . Em ambos os experimentos, os dados foram submetidos a ANOVA. Resultados: Experimento 1, os frangos de corte submetidos ao dos tratamentos 17/3.000 e controle nao apresentaram diferencas significativas (p>0,05) para as variáveis GteBS (202 y 224 N, respectivamente) e TiBS (338 y 332 N, respectivamente). Os frangos submetidos ao 13/2.900 apresentaram maior frequência de GS (menor capacidade de locomocao; 80% das aves com pontuação>3) e maior VAng (53% das aves com pontuação>2) do que os frangos do tratamento controle (0% das aves com pontuação GS>3 e 0% das aves com pontuação VAng>2). Experimento 2, os frangos do 16/3.000 apresentaram VAng, GS e TiBS semelhantes aos das aves do tratamento controle. Entretanto, as aves do tratamento 16/3.000 apresentaram GTeBS mais baixo (-26%) em comparacao as aves do tratamento de controle (p<0,05). Conclusões: A dieta com 16% PB e 3.000 kcal EM kg-1 não afetou a forca de ruptura da tíbia, gaite score marcha e angulação em valgus/varus de frangos de corte. Uma dieta com níveis de 16% de PB ou menos e 2.900-3.000 kcal EM kg-1 reduziu a resistência à ruptura do tendão e a resistência de tibia de frangos de corte.

ROLE OF CROSS LEG FLAPS IN LEG AND FOOT RECONSTRUCTION: OUR EXPERIENCE

Introduction: The management of compound trauma has always been challenging. Free ?aps are the ?rst choice when soft tissue cover cannot be provided by local ?aps. When facilities for microsurgery are not available or certain factors preclude the microsurgical anastomosis or in cases of free ?ap failure, the cross leg ?aps have a big role to play in lower limb reconstruction. We are presenting our retrospective study on 30 cases of distal leg and foot defects covered successfully by cross leg ?aps. The aim of this study is to highlight the usefulness of cross leg Aims and objectives: ?aps in lower limb reconstruction. A retrospective study was done on 30 patients from January 2015 to Material and methods: December 2021 who underwent perforator based fasciocutaneous cross leg ?ap for post traumatic soft tissue defects of distal leg and foot. The mechanism of injury, size and site of defect were recorded. All ?aps were planned in reverse and limbs were immobilised with external ?xator. Post-operative complications if any were noted. The patients were followed till the ?ap became stable. The mechanism of injury was road side accident in 26 cases, machine injury in 2 cases and fall from Results: height in 2 cases. 19 patients had soft tissue defect of distal 1/3rd of leg and 11 patients had foot defects. 26(86.67%) patients underwent distally based fasciocutaneous cross leg ?ap and 4(13.33%) patients underwent conventional anteromedially based fasciocutaneous ?ap. All ?aps survived well. 2 patients had discharge and 1 had margin necrosis but were managed conservatively. The perforators based fasciocutaneous cross leg ?aps provide an easy, simple, reliable and viable Conclusion: cover for distal leg and foot reconstruction.

Introduction: Venous ulcers are lesions developed mainly on the lower limbs. They cause continuous and disabling pain, impair mobility, alter self-image, and interfere with daily life activities. Venous ulcers are serious. They are caused by chronic venous insufficiency and permanent venous hypertension. People suffering from venous ulcers should receive comprehensive nursing care that contributes to self-care. Objective: To describe the strategies nursing professionals should consider for promoting self-care in people with venous ulcers. Method: Integrative review of the literature. Databases and electronic resources were searched: Medline using PubMed, Health, Epistemonikos, and SciELO. Research and review articles related to the study problem, published in English, Portuguese, or Spanish between 2010 and 2020, were included. This is a risk-free study, and copyrights were respected. Results: A sample of 41 publications was analyzed. The main themes derived from the analysis were the nursing care process and self-care, getting familiar with venous ulcers and therapeutic options, knowledge of compression therapy, and practice of healthy lifestyles. Conclusions: Nursing care for patients with venous ulcers should begin by recognizing a person from a holistic perspective and reciprocally with their environment. This approach implies a comprehensive care process that goes beyond the ulcer and values patients as active subjects of care so that they become familiar with their wounds and detect signs of improvement or warning. They can also know about compression therapy and therapeutic options and take the practice of healthy lifestyles into their daily lives.

Obesity effects on sleep quality with anthropometric and metabolic changes

SUMMARY OBJECTIVE: Obesity is one of the etiological factors of sleep disorders (e.g., obstructive sleep apnea and restless leg syndrome). The aim of this study was to determine the effect of obesity on sleep quality by using the Pittsburgh Quality İndex and Berlin Question are and evaluate the association of sleep with anthropometric and metabolic parameters. METHODS: A total of 76 patients (41 females and 35 males) between the ages of 18 and 70 years with a body mass index >30 kg/m2 were included in this study. Homeostatic model assessment-insulin resistance, hemoglobin A1c, alanine aminotransferase, aspartate transaminase, total cholesterol, low-density lipoprotein, triglyceride, high-density lipoprotein, and thyroid-stimulating hormone levels were analyzed. Sleep quality was evaluated with the Pittsburgh Sleep Quality Index, Berlin Questionnaire, and the Restless Leg Syndrome Questionnaire. RESULTS: A significant correlation was observed between Pittsburgh sleep quality index and body mass index, neck circumference, body fat index, muscle mass, hip and waist circumference, hemoglobin A1c, and homeostatic model assessment-insulin resistance (ps<0.005). The Pittsburgh sleep quality index median (2.5-97.5 percentile) value was 8 (2-18.6) in the patient group and 3.5 (0.1-7.9) in the control group (p<0.0001). Body mass index was found to be the predictor on Pittsburgh sleep quality index (R2=0.162, F=3.726, analysis of variance p=0.008). Notably, 88% (67) and 95% (57) of the poor sleepers were found to be at high risk for obstructive sleep apnea according to Berlin Questionnaire and Pittsburgh Sleep Quality Index, respectively. Also, the frequency of restless leg syndrome was 45% in obese individuals. CONCLUSIONS: We observed a significant correlation between Pittsburgh sleep quality index and the anthropometric and metabolic parameters. Also, the frequency of obstructive sleep apnea and restless leg syndrome was 88% and 45%, respectively, in obese individuals.

Association between inflammatory molecules, nitric oxide metabolites and leg ulcers in individuals with sickle cell anemia

Abstract Introduction Leg ulcers (LUs) are relatively common in patients with sickle cell anemia (SCA). The role of inflammation and nitric oxide (NO) pathways in the pathophysiology of the LU is not understood. Objective The aim of this study was to verify the association between inflammatory molecules and nitric oxide metabolites (NOx) and the occurrence of the LU in patients with SCA. Method It was a cross-sectional study on adult participants with SCA followed at Fundação Hemominas, a public blood center in Brazil. Eligible participants were recruited and included in one of two groups: Group 1, comprised of cases with SCA (Hb SS) and at least one LU at the time of inclusion in the study and Group 2, comprised of controls with SCA without a history of LU, matched by sex and age to cases. Participants were interviewed to obtain sociodemographic data and blood samples were collected. Clinical and laboratory data were abstracted from medical records. Nitric oxide metabolites (NOx) and inflammatory molecules were quantified using an immunoassay and Multiplex xMAP® technology, respectively. Eighty-seven individuals were included, ranging in age from 17 to 61 years (mean 40 ± 10.7 years); 30 had LU and 57 were controls without LU. Results Participants with LU had significantly higher levels of interleukin 8 (IL-8), IL-10, IL-15, NOx and platelet and white blood cell (WBC) counts, when compared to those without LU. Participants with LU had a significantly higher risk of having a history of osteomyelitis and a higher use of antiseptic soap in bathing, when compared to those without LU. Conclusion In conclusion, our results showed that NOx, inflammatory molecules and hematological features were associated with LU in Brazilian adults with SCA.

Utilidade do curativo compressivo elástico no enxerto de pele total nos membros inferiores: uma série de dois casos / Usefulness of elastic compression bandage on fullthickness skin graft in lower limbs: a series of two cases

A reconstrução com enxertia para defeitos resultantes de exérese de carcinoma espinocelular nos membros inferiores é um grande desafio para o cirurgião dermatológico, tendo em vista que uma pele muito fina para a área receptora, a não homogeneidade da vascularização local e a insuficiência venosa transitória dificultam a integração da pele enxertada nessas regiões. Para o sucesso desse tipo de procedimento, podem ser usadas algumas técnicas para reparar essas dificuldades, como um curativo compressivo elástico que utilizamos nos primeiros dias de pós-operatório de enxerto de pele total no pé e na perna, com bons resultados

Reconstruction with grafting for defects resulting from the removal of squamous cell carcinoma in the lower limbs is a great challenge for the dermatological surgeon. A very thin skin for the receiving area, the inhomogeneity of the local vascularization and the transient venous insufficiency make it difficult to integration of the grafted skin in these regions. For the success of this type of procedure, some techniques can be used to repair these difficulties, such as an elastic compressive dressing that we use in the first postoperative days of a total skin graft on the foot and leg, with good results
