Objetivo: Conocer las estrategias para asumir la vacunación contra el virus del papiloma humano en América Latina a partir de una revisión temática internacional, para encontrar experiencias que contribuyan a mantener resultados satisfactorios en Colombia. Materiales y métodos: Se realizó una revisión de literatura internacional en español, inglés y portugués sobre el estado de implementación y éxito del programa de vacunación en América Latina en bases de datos: Medline, Embase y Cochrane, portales de Organización Mundial y Panamericana de la Salud, páginas web de entes rectores y sitios electrónicos especializados en control del cáncer. Resultados: Se revisaron 97 referencias. En la región, diez países incorporaron dosis de la vacuna en sus esquemas para niñas entre 9 y 13 años; realizan diversas estrategias a corto plazo para mantener sus tasas de cobertura; siendo la articulación de los sectores salud-educación, el reconocimiento del contexto y la obligatoriedad las más exitosas. Conclusión: La situación en otros países en la implementación de la vacunación contra el VPH, muestra que la alianza entre salud, educación y comunicación es clave para mantener resultados satisfactorios. Educar y sensibilizar puede mantener la articulación con la comunidad. La aceptación o rechazo de la vacunación, depende del grado de información de la población; por tanto, es útil la consulta con profesionales de la salud y la aplicación de consentimiento informado para reducir la incertidumbre

Objective: To know the strategies to take responsibility for vaccination against human papillomavirus infection in Latin America through an international thematic review to find experiences that contribute to maintain satisfactory results in Colombia. Materials and methods: A review of international literature in Spanish, English and Portuguese about the state of implementation and achievement of the vaccination programs used in Latin America was carried out using the Medline, Embase and Cochrane Library electronic databases, portals of the World Health Organization and Pan American Health Organization, governmental websites, and websites specialized in cancer control. Results: Ninety-seven references were reviewed. Ten countries in the region incorporated the vaccine doses in their program among 9 and 13 years old girls. They perform several short-term strategies to maintain their coverage rates, being the articulation between the health-education sectors, the context recognition, and their obligatory nature the most successful. Conclusion: The situation in other countries regarding the implementation of an HPV-vaccination program shows that the alliance between healthcare, education and communication is the key to the sustainability of satisfactory results. Educating and raising awareness can maintain the articulation with the community. The acceptance or rejection of the vaccine depends on the degree of information of the population. Therefore, consultation with health-professionals and the application of informed consent are useful to reduce uncertainty.

Needle gauge and tip designs for preventing post-dural puncture headache (PDPH).

BACKGROUND: Post-dural puncture headache (PDPH) is one of the most common complications of diagnostic and therapeutic lumbar punctures. PDPH is defined as any headache occurring after a lumbar puncture that worsens within 15 minutes of sitting or standing and is relieved within 15 minutes of the patient lying down. Researchers have suggested many types of interventions to help prevent PDPH. It has been suggested that aspects such as needle tip and gauge can be modified to decrease the incidence of PDPH. OBJECTIVES: To assess the effects of needle tip design (traumatic versus atraumatic) and diameter (gauge) on the prevention of PDPH in participants who have undergone dural puncture for diagnostic or therapeutic causes. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, CINAHL and LILACS, as well as trial registries via the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) search portal in September 2016. We adopted the MEDLINE strategy for searching the other databases. The search terms we used were a combination of thesaurus-based and free-text terms for both interventions (lumbar puncture in neurological, anaesthesia or myelography settings) and headache. SELECTION CRITERIA: We included randomized controlled trials (RCTs) conducted in any clinical/research setting where dural puncture had been used in participants of all ages and both genders, which compared different tip designs or diameters for prevention of PDPH DATA COLLECTION AND ANALYSIS: We used the standard methodological procedures expected by Cochrane. MAIN RESULTS: We included 70 studies in the review; 66 studies with 17,067 participants were included in the quantitative analysis. An additional 18 studies are awaiting classification and 12 are ongoing. Fifteen of the 18 studies awaiting classification mainly correspond to congress summaries published before 2010, in which the available information does not allow the complete evaluation of all their risks of bias and characteristics. Our main outcome was prevention of PDPH, but we also assessed the onset of severe PDPH, headache in general and adverse events. The quality of evidence was moderate for most of the outcomes mainly due to risk of bias issues. For the analysis, we undertook three main comparisons: 1) traumatic needles versus atraumatic needles; 2) larger gauge traumatic needles versus smaller gauge traumatic needles; and 3) larger gauge atraumatic needles versus smaller gauge atraumatic needles. For each main comparison, if data were available, we performed a subgroup analysis evaluating lumbar puncture indication, age and posture.For the first comparison, the use of traumatic needles showed a higher risk of onset of PDPH compared to atraumatic needles (36 studies, 9378 participants, risk ratio (RR) 2.14, 95% confidence interval (CI) 1.72 to 2.67, I2 = 9%).In the second comparison of traumatic needles, studies comparing various sizes of large and small gauges showed no significant difference in effects in terms of risk of PDPH, with the exception of one study comparing 26 and 27 gauge needles (one study, 658 participants, RR 6.47, 95% CI 2.55 to 16.43).In the third comparison of atraumatic needles, studies comparing various sizes of large and small gauges showed no significant difference in effects in terms of risk of PDPH.We observed no significant difference in the risk of paraesthesia, backache, severe PDPH and any headache between traumatic and atraumatic needles. Sensitivity analyses of PDPH results between traumatic and atraumatic needles omitting high risk of bias studies showed similar results regarding the benefit of atraumatic needles in the prevention of PDPH (three studies, RR 2.78, 95% CI 1.26 to 6.15; I2 = 51%). AUTHORS' CONCLUSIONS: There is moderate-quality evidence that atraumatic needles reduce the risk of post-dural puncture headache (PDPH) without increasing adverse events such as paraesthesia or backache. The studies did not report very clearly on aspects related to randomization, such as random sequence generation and allocation concealment, making it difficult to interpret the risk of bias in the included studies. The moderate quality of the evidence for traumatic versus atraumatic needles suggests that further research is likely to have an important impact on our confidence in the estimate of effect.

Predictors of Persistent Neuropathic Pain--A Systematic Review.

BACKGROUND: Characterization of the prognostic variables for persistent neuropathic pain (PNP) remains incomplete despite multiple articles addressing this topic. To provide more insight into the recovery and prognosis of neuropathic pain, high-quality data are required that provide information about the predictors that contribute to the development of PNP. OBJECTIVE: To determine the methodological quality of studies about predictors for PNP and to summarize findings of predictors found in high-quality studies. STUDY DESIGN: A systematic review. SETTING: VU University Medical Center, Amsterdam, The Netherlands. METHODS: Studies were identified by searching the electronic databases PubMed, Embase, and Cochrane Library. Methodological quality of each article was independently assessed by 2 reviewers. RESULTS: Forty-six relevant studies were identified, classified into 4 different neuropathic pain (NP)-syndromes: postherpetic neuralgia (n = 35), radicular pain and sciatica (n = 3), postsurgical pain (n = 6), and other types of NP (n = 2). Seven studies were of high quality. The 3 high-quality studies found for PHN reported male gender, older age, smoking, trauma at the site of lesion, missed antiviral prescriptions, higher acute pain severity, higher rash severity, more neuropathic characteristics, shorter rash duration, and a lower health status as predictors for PNP. For persistence of radicular pain one high-quality study reported negative outcome expectancies, pain-related fear of movement, and passive pain coping as predictors for PNP. Psychological distress, acute pain, breast cancer surgery, higher body mass index, area of secondary hyperalgesia, neuropathic characteristics, hypoesthesia, and hyperesthesia were found to be predictive for postsurgical pain in 3 high-quality studies. LIMITATIONS: Some publications may have been missed during literature search. The low-quality of the studies could be the result of an incomplete description of their methods. CONCLUSIONS: High-quality studies mainly assessed factors related to disease functions and structures. Due to shortcomings in methodological quality and limited areas of predictor selection, there is a need for high-quality studies focusing on predictor measurement, statistical analysis and the use of a standardized set of predictors.

Intravenous magnesium for chronic complex regional pain syndrome type 1 (CRPS-1).

OBJECTIVE: To assess the effects of intravenous administration of magnesium on complex regional pain syndrome type 1 (CRPS-1), a randomized double-blind placebo-controlled trial was performed. METHODS: Fifty-six patients with CRPS-1 (International Association for the Study of Pain Orlando criteria) received MgSO(4) 70 mg/kg or placebo (NaCl 0.9%) in 4 hours over 5 consecutive days. Pain (BOX-11 and McGill), the level of impairment (Impairment level Sum Score [ISS]), functional limitations (Radboud Skills Questionnaire, Walking Skills Questionnaire/questionnaire rising and sitting down), participation (Impact on Participation and Autonomy [IPA]), and quality of life (Short Form-36, EuroQol, IPA) were evaluated at baseline and at 1, 3, 6, and 12 weeks. RESULTS: No significant differences were found between MgSO(4) and placebo on the BOX-11 and ISS at different time points during the trial on intention-to-treat and per-protocol analysis. A significant improvement on the BOX-11 was found after the first week of the trial in both groups (mean 0.7; standard deviation 1.1). For the MgSO(4) group, a clinically relevant and statistically significant improvement on the ISS at 1 week (median 5, interquartile range [IQR] -1 to 8) and a significant improvement on the McGill up to 6 weeks (median 2 words, IQR 0-4.5) were found compared with baseline, which were not found in the placebo group. Significant improvement in perceived job participation was found for the MgSO(4) group at 12 weeks (median improvement 1.44-1.17; P = 0.01). ISS improved significantly more in patients with a low Hospital Anxiety and Depression Scale (HADS) score (≤10) in the MgSO(4) group (mean 4.4 vs mean -3.1; P = 0.02). CONCLUSION: Administration of the physiological competitive N-methyl-D-aspartate receptor antagonist magnesium in chronic CRPS provides insufficient benefit over placebo. Future research should focus on patients with acute CRPS and early signs and symptoms of central sensitization.

An overview of predictors for persistent neuropathic pain.

Neuropathic pain (NP) is a pain arising as a direct consequence of a lesion or disease affecting the somatosensory system. A variety of factors associated with the development of persistent NP have been suggested. The goal of the present article is to provide an overview of current knowledge about prognostic factors for persistent NP. The International Classification of Functioning, Disability and Health model is used as a framework to categorize these predictors. Most reported predictors in the literature were found in the International Classification of Functioning, Disability and Health-category of personal factors, especially age and psychological factors, functions and structure, including sensory signs and symptoms. Predictors in the category of environmental factors, activities and participation were less frequently described.

Predictors for persistent neuropathic pain--a Delphi survey.

BACKGROUND: Chronic neuropathic pain has a major effect on quality of life. In order to prevent neuropathic pain from becoming chronic and improve neuropathic pain care, it is important to identify predictors associated with the persistence of neuropathic pain. OBJECTIVE: To identify potential predictors associated with the persistence of neuropathic pain. STUDY DESIGN: A 2-round Delphi study. SETTING: University Medical Center and Pain Management Research Center. METHODS: A 2-round Delphi study was conducted among 17 experts in the field of neuropathic pain. Selection of the panel was based on the citation index ranking for neuropathic pain-related research and/or membership in the neuropathic pain special interest group of the International Association for the Study of Pain (IASP), complemented with experts with demonstrated field knowledge.Potential predictors were categorized according to the International Classification of Functioning, Disability and Health model. Participants were asked to identify important predictors, suggest new predictors, and grade the importance on a 0-10 scale. For the second round, predictors were considered important if the median score was ≥ 7 and the interquartile range (IQR) ≤ 3. RESULTS: In the first round, 20 predictors were selected and 58 were added by the experts (patient characteristics [15], environmental factors [25], functions & structure [4], participation & health related quality of life [14]). In the second round, 12 predictors were considered important (patient characteristics [4; e.g., depression, pain catastrophizing], environmental factors [surgery as treatment for neuropathic pain], functions & structure [6; e.g., allodynia, duration of the complaints], participation & trait anxiety/depression as a part of health related quality of life). Presence of depression and pain catastrophizing were considered the most important predictors for chronic neuropathic pain (median ≥ 8; IQR ≤ 2). LIMITATIONS: The study design did not include plenary discussion among the experts. The meaning of the individual topics used in this study could have been subject to interpretation bias. CONCLUSIONS: Overall, psychological factors and factors related to sensory disturbances were considered important predictors for persistence of neuropathic pain. Activity related factors and previously received paramedical and alternative treatment were considered to be less important. The list of possible predictors obtained by this study may serve as a basis for development of a clinical prediction rule for chronic neuropathic pain.
