Results from a cross-sectional, observational study to assess inadequate pain relief in patients with knee and/or hip osteoarthritis in Mexico.

INTRODUCTION AND OBJECTIVES: There is limited data that characterizes osteoarthritis (OA) patients who experience moderate to severe pain despite analgesic treatment in Mexico. In this study, we estimate the real-world prevalence of inadequate pain relief (IPR) among individuals with knee and/or hip OA who have been prescribed analgesic therapy and characterize this patient population for each country separately. MATERIALS AND METHODS: This is a multinational, multi-site, cross-sectional, observational study. Participating physicians enrolled patients over 50 years of age with diagnosed knee and/or hip OA who had been prescribed topical and/or oral pain medication for at least 30 days prior to study visit, extracted data from their medical charts, and collected patient data using established questionnaires. RESULTS: 301 patients treated by 35 physicians in Mexico were enrolled in the study. More than half of the patients (53%) met the definition of IPR. Patients with IPR were significantly older (66.8 vs. 63.5 years, p=0.002) and were more likely to be obese (24.2% vs. 11.9%, p=0.006). Patients in the IPR group were more likely to report moderate/severe problems across all 5 dimensions of the EQ-5D and reported higher scores, indicating worse outcomes, on all three WOMAC subscales. Patients in the IPR group also reported reduced work productivity and greater treatment dissatisfaction compared to patients without IPR. DISCUSSION AND CONCLUSIONS: IPR is highly prevalent among individuals with knee and/or hip OA in Mexico. Patients with IPR experience decreased health-related quality of life HRQoL and work productivity, impaired function, and poor treatment satisfaction. Health care professionals need to be aware of the high prevalence of IPR, work toward improving OA patient management, and facilitate early intervention or changes in drug and other treatment modalities.

Tratamiento conservador de la artrosis de cadera / Conservative treatment of hip osteoarthritis

Ante un escenario clínico de coxalgia por artrosis de cadera se planteó la necesidad de conocer los tratamientos con-servadores más seguros y efectivos para el manejo del dolor. El tratamiento de la artrosis requiere un enfoque integral e individualizado en función de las preferencias del paciente para lograr el máximo beneficio clínico. Existen numerosas estrategias útiles para el manejo del dolor en pacientes con artrosis de cadera siendo fuertemente recomendados de inicio la actividad física, los antiinflamatorios no esteroideos (AINE) orales y en ciertos casos los corticoides intraarticulares, tramadol o duloxetina, siempre asociado con la actividad física. Los ejercicios más recomendados son los aeróbicos y el Tai Chi o yoga. (AU)

Faced with a clinical scenario of coxalgia due to hip osteoarthritis, the need to know the safest and most effective conservative treatments for pain management arose. The treatment of osteoarthritis requires a comprehensive and individualised approach based on the patient's preferences to achieve maximum clinical benefit. There are numerous useful strategies for pain management in patients with hip osteoarthritis being strongly recommended from the beginning such as physical activity, oral non-steroidal anti-inflammatory drugs (NSAID) and in certain cases intra-articular corticosteroids, tramadol or duloxetine, always associated with physical activity. The most recommended exercises are aerobics and Tai Chi or yoga. (AU)

Osteoarthritis of the hip conservative treatment with type A botulinum toxin.

INTRODUCTION: Osteoarthritis (OA) of the hip is a low-grade inflammatory disease of multiple etiology that has a limited conservative management and insufficiently explored. The application of botulinum toxin type A (BoNT-A) produces in the applied muscle a temporary, delimitable and reversible flaccid paralysis, which applied in a strategic way achieves to reduce mechanical stress and pain. OBJECTIVE: To evaluate the effect on pain perception, functionality and rigidity and changes in flexibility, internal and external rotation, before and 90 days after the application of BoNT-A. METHODS: Clinical, experimental, longitudinal, open study, with a total of 35 patients and 45 hips treated. BoNT-A of 500 U was applied in iliac, adductor brevis and longus muscles. RESULTS: The Wilcoxon test was used to compare the evaluation scores on days 0-90, observing the decrease in referred pain (p < 0.0001), rigidity (p < 0.002), improved perceived function (p < 0.001) and mobility arcs: flexion, internal and external rotation (p < 0.0001). CONCLUSIONS: The treatment with BoNT-A provides a conservative and safe option for the management of symptoms and physical restraint caused by hip OA.

Mielosupresión inducida por linezolid: un caso pediátrico / Myelosupression induced by linezolid: a pediatric case

El linezolid es un antibiótico de la familia de las oxazolidinonas, que actúa inhibiendo la síntesis proteica. Se emplea en infecciones graves por cocos Gram-positivos multirresistentes. Sus principales efectos secundarios son los gastrointestinales y, con menor frecuencia, la neuropatía periférica, la acidosis láctica y la mielosupresión. Se presenta el caso clínico de un niño de 12 años con diagnóstico de osteoartritis séptica de cadera derecha con osteomielitis femoral en tratamiento con linezolid, que presentó un cuadro de intolerancia digestiva, asociado a astenia y pérdida de peso. Presentaba, además, anemia normocítica, junto con leucopenia y trombopenia leves, con datos sugestivos de alteración de la hematopoyesis en el frotis sanguíneo, sugerente de toxicidad por fármacos. El cuadro se resolvió con la interrupción de la administración del fármaco. La mielosupresión reversible asociada a linezolid se relaciona con tratamientos prolongados (> 28 días), por lo que son necesarios los controles hematológicos periódicos durante ellos.

Linezolid is an antibiotic of oxazolidinones family that inhibits proteical synthesis. It is used in several Gram-positive multirresistent infections. Its more frequent side effects are gastrointestinal, followed by peripheral neuropathy and myelosuppression. We report the case of a 12-year-old boy diagnosed with septic osteoarthritis of the hip and femoral osteomyelitis, following treatment with linezolid, who complained about digestive intolerance and weight loss. He showed severe normocytic anemia and mild leukopenia and thrombocytopenia with data of hematopoiesis disorder in the blood smear that suggested drug toxicity. These findings reverted when the treatment was discontinued. Reversible myelosuppression associated with linezolid is related to long treatments (more than 28 days). So it is necessary to check the blood count during long treatments.

The effectiveness of tipi in the treatment of hip and knee osteoarthritis: a preliminary report

Osteoarthritis (OA) is a common painful inflammatory condition occurring mainly in the later half of life. Hipe and knee are the joints mostly affected. Petiveria alliacea (tipi) popularly known as an anti-rheumatic medicine, has been used by OA patients to relief pain. This one-week cross-over double-blind trial has preliminary evaluated the analgesic effect of tipi tea in 14 patients with hip and knee OA. Imperata exaltata (sape) was used as the Placebo tea. The pain assessments that were made at baseline and before the start of the second treatment period by treatment groups were comparable. While taking tipi or placebo tea patients experienced a statistically significant improvement in pain on motion and pain at night. The comparison between the improvements reported while on tipi and placebo tea, however, did not disclose any statistically significant difference. At the conclusion of the study 7 patients preferred tipi tea and 6 preferred placebo tea (NS). Two patients reported insomnia, one durign placebo treatment and the other during tipi treatment. In this preliminary report both teas succeeded in the aim of relieving pain
