Objective: There are limited studies in Latin America regarding the chronic consequences of the Chikungunya virus (CHIK), such as post-CHIK chronic inflammatory rheumatism (pCHIK-CIR). We assessed the largest cohort so far of pCHIK-CIR in Latin America, at the municipality of La Virginia, Risaralda, a new endemic area of CHIK in Colombia. Methods: We conducted a cohort retrospective study in Colombia of 283 patients diagnosed with CHIK that persisted with pCHIK-CIR after a minimum of 6 weeks and up to a maximum of 26.1 weeks. pCHIK cases were identified according to validated criteria via telephone. Results: Of the total CHIK-infected subjects, 152 (53.7%) reported persistent rheumatological symptoms (pCHIK-CIR). All of these patients reported joint pains (chronic polyarthralgia, pCHIK-CPA), 49.5% morning stiffness, 40.6% joint edema, and 16.6% joint redness. Of all patients, 19.4% required and attended for care prior to the current study assessment (1.4% consulting rheumatologists). Significant differences in the frequency were observed according to age groups and gender. Patients aged >40 years old required more medical attention (39.5%) than those ≤40 years-old (12.1%) (RR=4.748, 95%CI 2.550-8.840). Conclusions: According to our results, at least half of the patients with CHIK developed chronic rheumatologic sequelae, and from those with pCHIK-CPA, nearly half presented clinical symptoms consistent with inflammatory forms of the disease. These results support previous estimates obtained from pooled data of studies in La Reunion (France) and India and are consistent with the results published previously from other Colombian cohorts in Venadillo (Tolima) and Since (Sucre).

The potential for development of tolerance and dependence and the risk of side effects of opioids make it necessary to monitor their prescribing patterns in order to decrease the morbidity and mortality associated with their continued use. The objective of this study was to determine prescription patterns of opioid medication in a group of patients through a cross-sectional study on a population database of 3.5 million people. Patients with three months of continuous opioid use were identified. Pharmacological, co-medication and cost variables were analyzed. We conducted a multivariate analysis. A total of 7,457 patients were included; 72.1% were women, the mean age was 65.1 years, and 3.8% had a diagnosis of cancer. 10.2% of the patients received opioids in combination therapy. The most prescribed opioids were codeine (57.7%), tramadol (30.9%), and hydrocodone (10.4%). The great majority of patients (91.8%) received pharmacological co-medication with antihypertensive agents (54.4%), statins (38.2%) and acetaminophen (35.4%). The use of other analgesics such as acetaminophen (OR: 1.45, 95% CI: 1.22 -1.75) or nonsteroidal anti-inflammatory drugs (OR: 1.98, 95% CI: 1.60 -2.44) was associated with increased risk of receiving opioids in combination therapy. Prescribing habits of weak agonists and short-acting opioids predominate, mainly in monotherapy and at lower than recommended doses.

Introducción: la enfermedad de Parkinson es considerada la segunda causa de enfermedad neurodegenerativa, en la que se destacan signos y síntomas motores como temblor, bradicinesia, rigidez e inestabilidad postural, acompañados de síntomas no motores como alteraciones del sueño, autonómicas, cognitivas, gastrointestinales, entre otras. El tratamiento farmacológico de la enfermedad al inicio suele ser útil, pero cuando los síntomas persisten, el tratamiento falla o no se toleran sus reacciones adversas, es necesario considerar alternativas como la estimulación cerebral profunda. Metodología: revisión narrativa con énfasis en los aspectos clínicos de la terapia con estimulación cerebral profunda en los pacientes con enfermedad de Parkinson. Discusión: la estimulación cerebral profunda es una técnica quirúrgica en la que se implantan electrodos en regiones cerebrales específicas, generalmente el núcleo subtalámico, globo pálido interno o núcleo ventral intermedio del tálamo, y se conectan a un marcapasos subcutáneo desde donde se modula eléctricamente la actividad de estas áreas. Esta terapia ha mostrado ser costo-efectiva, aporta beneficios considerables en la mejoría de los síntomas de la enfermedad de Parkinson y cuenta con evidencia clínica en los pacientes que han sido seleccionados correctamente.
