El ozono intrarticular modula la inflamación, mejora el dolor, la rigidez, la función y tiene un efecto anabólico sobre la artrosis de rodilla: estudio cuasiexperimental prospectivo tipo antes-después, 115 pacientes / Intra-articular ozone modulates inflammation, ameliorates pain and stiffness, improves function and has anabolic effect on knee osteoarthritis: a prospective quasiexperimental before-and-after study, 115 patients

OBJETIVO: El objetivo del presente estudio es verificar por primera vez en la literatura el efecto sintomático y modificador de enfermedad del ozono (O2-O3) mediante la mejoría clínica (dolor, función y rigidez), bioquímica (proteína C-reactiva [PCR], velocidad de sedimentación globular [VSG], ácido úrico) y radiológica (mínimo espacio articular medial y lateral) en una serie de pacientes con artrosis de rodilla. MATERIAL Y MÉTODOS: Se realizó un estudio cuasiexperimental prospectivo tipo antes y después a 115 pacientes con artrosis de rodilla con Kellgren-Lawrence grado 2 o más. El protocolo de ozono consistió en 4 sesiones (una sesión/semana) de una infiltración intrarticular de 20 ml de una mezcla médica de oxígeno-ozono (95-5 %) a una concentración de 20 μg/ml. Las variables de resultado incluyeron variables clínicas (dolor, rigidez y función), bioquímicas (PCR, VSG, ácido úrico) y radiológicas (mínimo espacio articular femorotibial). RESULTADOS: La edad media de los pacientes fue de 64.81 ± 11.22 años. Los pacientes femeninos representaron el 75.6 % (n = 87), con una relación mujer/hombre de 3:1. VARIABLES BIOQUÍMICAS: la PCR disminuyó de 0.42 ± 0.54 mg/dl a 0.31 ± 0.33 mg/dl (p = 0.0142). La VSG disminuyó sus valores desde 14.52 ± 10.14 mm/h hasta 13.08 ± 8.78 mm/h (p = 0,0014). El ácido úrico en suero disminuyó su valor de 5.12 ± 1.22 mg/dl a 5.05 ± 1.24 (p = 0.1307). VARIABLES CLÍNICAS: el ozono (O2-O3) mejoró significativamente las variables clínicas dolor, rigidez y función (p = 0.0000). El dolor medido por EVA fue de 7.11 ± 1.11 puntos y disminuyó significativamente a 3.56 ± 1.56 puntos (p = 0.0000). Antes de la intervención, la subescala WOMAC-dolor fue de 14.3 ± 2.29 puntos y disminuyó a 7.13 ± 3.13 puntos (p = 0.0000), la subescala WOMAC-rigidez fue de 2.73 ± 1.39 puntos y disminuyó a 1.16 ± 1.13 puntos (p = 0.0000), la subescala WOMAC-función fue de 41.66 ± 8.1 puntos y mejoró a 25.29 ± 9.72 puntos (p = 0.0000). VARIABLES RADIOLÓGICAS: en 53 pacientes analizados radiológicamente (según protocolo estandarizado) al año de seguimiento después del tratamiento con ozono, el compartimento interno aumento significativamente de 4.12 ± 1.41 mm a 4.4 ± 1.35 mm (p = 0.0008) y el compartimento externo aumentó de 6 ± 1.37 a 6.16 ± 1.4 mm (p = 0.0753). CONCLUSIONES: El ozono intrarticular ha demostrado efecto sintomático y modificador de la enfermedad en los pacientes con artrosis de rodilla, mejorando el dolor, la función y la rigidez; disminuyendo los marcadores de inflamación (PCR, VSG y ácido úrico), y aumentando el mínimo espacio articular del componente medial y lateral evidenciado radiológicamente. En este estudio se ha evidenciado que el ozono modula la inflamación, disminuye el dolor y la rigidez, mejora la función y tiene efecto anabólico en los pacientes con artrosis de rodilla. No se ha observado ningún efecto adverso tras las infiltraciones intrarticulares de ozono

PURPUSE: The objective of the present study is to verify for the first time in the literature the symptomatic and modifying disease effect of ozone (O2-O3) through clinical (pain, function and stiffness), biochemical (C-reactive protein [CRP], erythrocyte sedimentation rate [ESR], uric acid) and radiological improvement (minimum medial and lateral joint space) in a series of patients with osteoarthritis of the knee. METHODS: A prospective quasi-experimental beforeand-after study was performed in 115 patients with knee osteoarthritis Kellgren-Lawrence grade 2 or more. The ozone protocol consisted of 4 sessions (one session / week) of an intra-articular injection of 20 ml of a medical mixture of Oxygen-Ozone (95-5ºC) at a concentration of 20 μg / ml. Outcome variables included clinical (pain, stiffness, and function), biochemical (CRP, ESR, uric acid), and radiological variables (minimal femorotibial joint space). RESULTS: Mean age of the patients was 64.81 ± 11.22 years. Female patients accounted for 75.6 % (n = 87), with a female / male ratio of 3 : 1. Biochemical-variables: CRP decreased from 0.42 ± 0.54 mg/dL to 0.31 ± 0.33 mg/dL (p = 0.0142). ESR decreased from 14.52 ± 10.14 mm/h to 13.08 ± 8.78 mm/h (p= 0.0014). Serum uric acid decreased from 5.12 ± 1.22 mg/dL to 5.05 ± 1.24 (p = 0.1307). CLINICAL VARIABLES: Ozone (O2-O3) significantly improved pain, stiffness and function clinical variables (p = 0.0000). Pain measured by VAS was 7.11 ± 1.11 points and decreased significantly to 3.56 ± 1.56 points (p = 0.0000). Before the intervention, WOMAC-pain subscale was 14.3 ± 22.29 points and decreased to 7.13 ± 33.13 points (p = 0.0000), WOMAC-stiffness subscale was 2.73 ± 1.39 points and decreased to 1.16 ± 1.13 points (p = 0.0000), WOMAC-function subscale was 41.66 ± 8, 1 points and improved to 25.29 ± 9.72 points (p = 0.0000). RADIOLOGICAL VARIABLES: In 53 patients analyzed radiologically (according to standardized protocol) at one year of follow-up after ozone treatment, the internal compartment increased significantly from 4.12 ± 1.41 mm to 4.4 ± 1.35 mm (p = 0.0008) and the external compartment increased from 6 ± 1.37 to 6.16 ± 1.4 mm (p = 0.0753). CONCLUSIONS: Intra articular ozone has demonstrated a symptomatic and disease modifying effect in patients with osteoarthritis of the knee, improving pain, function and stiffness; decreasing markers of inflammation (CRP, ESR and uric acid), and increasing the minimal joint space of the medial and lateral component evidenced radiologically. In this study it has been shown that ozone modulates inflammation, decreases pain and stiffness, improves function and has an anabolic effect in patients with osteoarthritis of the knee. No adverse effect has been observed after intra articular infiltrations of ozone

Short and mid-term outcomes and functional results in metal-on-metal hip resurfacing arthroplasty at 5 years follow-up: the Spanish experience.

BACKGROUND: Hip resurfacing arthroplasty (HRA) and in particular, Birmingham hip resurfacing (BHR), is commonly employed as an alternative to total hip arthroplasty (THA) in young patients, as it allows for preservation of femoral bone stock and resumption of physical activity. The aim of our study was to investigate 5-year survival and functional outcomes of BHR arthroplasty in young Spanish osteoarthritis (OA) patients. METHODS: This is an observational, prospective, cohort study of patients who underwent BHR between June 2005 and December 2009 at a Spanish public hospital with a minimum follow-up of 5 years. All surgeries were performed by a single surgeon (RLM). Survival was analyzed using the Kaplan-Meier method. Functional outcomes and return to work and physical activities were also assessed. RESULTS: Five-year survival rate of the prosthesis was 95.74% (95% CI: 95.77-98.07), and estimated 10-year survival was 92.92% (95% CI: 85.07-96.72). Harris hip score significantly increased from 41.13 to 97.63 (p < 0.001) at 5-year follow-up. Average time for returning to work and sporting activities was 3.89 (SD: 2.39) and 3.47 (SD: 1.18) months respectively. Failure occurred in 14 patients, 8 of whom experienced femoral neck fractures. CONCLUSIONS: Our data support the short and mid-term efficacy of BHR arthroplasty in young OA patients, indicating good implant survival, improvement in patients' functionality and a swift return to work and physical activities after surgery.

Male Urinary Incontinence: Associated Risk Factors and Electromyography Biofeedback Results in Quality of Life.

The aim of the current study was to determine the demographic characteristics and risk factors associated with male urinary incontinence (UI) and to assess the effectiveness and the effect on the quality-of-life of a pelvic floor muscle training (PFMT) protocol with electromyography-biofeedback (EMG-BFB) with surface electrodes. A prospective, quasi-experimental before-and-after study with a sample of 61 men out of 372 patients referred to the Pelvic Floor Unit from October 2005 to June 2012 was performed. The protocol consisted of 20 sessions of EMG-BFB supervised by a physiotherapist twice a week. The session durations were 30 minutes (118 work/rest cycles of pelvic muscles). Work lasted 3 seconds and rest 7 seconds. Patients were given standards of conduct and questionnaires (International Consultation on Incontinence-Short Form and Incontinence Quality-of-Life Measure) at the beginning and at the end of the treatment. The average age was 64.85 ± 14.34 years; 44.3% (n = 27) had benign prostatic hypertrophy, 41.9% (n = 25) had prostate malignant neoplasm, 86.9% (n = 53) had undergone prostatectomy, 16.4% (n = 10) had undergone abdominal surgery. Abdominal surgery and radical prostatectomy were significantly associated with UI (p < .05). Stress urinary incontinence was the most common type of UI (86.67%), followed by mixed urinary incontinence (8.33%) and urge urinary incontinence (5%). A significant improvement (p < .05) in both International Consultation on Incontinence-Short Form and Incontinence Quality-of-Life Measure questionnaires was observed when making comparisons regarding the results before and after the EMG-BFB treatment protocol. These results support that male UI is significantly associated with urological and abdominal surgery (including radical prostatectomy) and that EMG-BFB for PFMT improves incontinence and quality of life (social embarrassment, limiting behavior, and psychosocial impact) in the three types of UI on an overall basis.
