Treatments for hypersensitive noncarious cervical lesions: a Practitioners Engaged in Applied Research and Learning (PEARL) Network randomized clinical effectiveness study.

ABSTRACT: BACKGROUND:The Practitioners Engaged in Applied Research and Learning (PEARL) Network conducted a three-armed randomized clinical study to determine the comparative effectiveness of three treatments for hypersensitive noncarious cervical lesions (NCCLs): use of a potassium nitrate dentifrice for treatment of hypersensitivity, placement of a resin-based composite restoration and placement of a sealant. METHODS:Seventeen trained practitioner-investigators (P-Is) in the PEARL Network enrolled participants (N = 304) with hypersensitive posterior NCCLs who met enrollment criteria. Participants were assigned to treatments randomly. Evaluations were conducted at baseline and at one, three and six months thereafter. Primary outcomes were the reduction or elimination of hypersensitivity as measured clinically and by means of patient-reported outcomes. RESULTS:Lesion depth and pretreatment sensitivity (mean, 5.3 on a 0- to 10-point scale) were balanced across treatments, as was sleep bruxism (present in 42.2 percent of participants). The six-month participant recall rate was 99 percent. Treatments significantly reduced mean sensitivity (P < .01), with the sealant and restoration groups displaying a significantly higher reduction (P < .01) than did the dentifrice group. The dentifrice group's mean (standard deviation) sensitivity at six months was 2.1 (2.1); those of the sealant and restoration groups were 1.0 (1.6) and 0.8 (1.4), respectively. Patient-reported sensitivity (to cold being most pronounced) paralleled clinical measurements at each evaluation. CONCLUSIONS:Sealing and restoration treatments were effective overall in reducing NCCL hypersensitivity. The potassium nitrate dentifrice reduced sensitivity with increasing effectiveness through six months but not to the degree offered by the other treatments. Practical Implications. Sealant or restoration placement is an effective method of immediately reducing NCCL sensitivity. Although a potassium nitrate dentifrice did reduce sensitivity slowly across six months, at no time was the reduction commensurate with that of sealants or restorations.

Project description:BackgroundSince the mid-1990 s, there have been growing efforts to prevent cervical cancer in less-developed countries through the development of innovative screening approaches such as visual inspection of the cervix associated with same day management of cervical lesions with cryotherapy or loop electrosurgical excision procedure (LEEP). In the past, promising cancer screening interventions have been widely promoted despite incomplete evidence, only to become the subject of intense controversies about ensuing net health benefit. Because the efficacy and effectiveness of the new protocols for global cervical cancer screening have not been well characterized yet, and as a contribution to the evaluation of the balance between the benefits and risks of these protocols, we reviewed the literature on the safety of cryotherapy and LEEP for cervical intraepithelial neoplasia (CIN) in low- and middle-income countries.MethodsWe searched 12 databases (Medline, Google Scholar, Scopus, Cochrane Library, Web of Science, OCLC, PAIS International Database, WHO Global Health Library, CINAHL, Science.gov, NYAM Grey Literature Report, and POPLINE) for original research published between January 1995 and April 2009. Both peer-reviewed publications and items of "grey" literature were retrieved; no language restriction was applied. We calculated the median (minimum, maximum) reported rate for each harm considered. Because of limitations and heterogeneity in the data, no formal meta-analysis was performed.ResultsThe search identified 32 articles that reported safety data from 24 cryotherapy and LEEP studies. The combined sample consisted of 6,902 women treated by cryotherapy and 4,524 women treated by LEEP. Most studies were conducted in reference or research settings in Asia and Africa. Short-term harms of cryotherapy and LEEP appeared to be similar to those described in the literature from high-income countries. Information was sparse on HIV-related harms and long-term reproductive outcomes of treatment.ConclusionsWhen performed in resource-limited settings by qualified providers, cryotherapy and LEEP are not associated with excess harm. However, available data are insufficient to propose fully evidence-based protocols for routine screening of HIV-infected women and women of reproductive age.

Project description:BackgroundCervical pain is a problem with a high prevalence of ~13% of the population, and is more common in women (16.5%). The most affected age group is 65-74 years. Our aim was to assess the effectiveness of self-applied acupressure for decreasing benign-origin cervical pain, under the supervision of a health professional and in combination with usual treatment, as well as to examine its impact on the patient's self-perceived health condition and their opinion of the technique.MethodsPragmatic, multicenter, controlled clinical trial randomized by healthcare center. A total of 160 patients with benign-origin cervical pain between 18 and 65 years of age who attended primary care were included from 12 healthcare centers in the autonomous community of Madrid by consecutive sampling, and randomly assigned to a control or intervention group. The main outcome variable was pain intensity measured on a visual analogue scale (VAS) and secondary variables were self-perceived quality of life (EuroQol-5D utility index) and functional ability (neck disability index). An explanative model of generalized estimating equations was built taking into account the lack of independence among observations. The analysis was performed over 6 months.ResultsIn total, 150 patients completed the study. Mean age was 45 years (SD: 10.7), 86.7% were women, 86.2% were currently employed, and 57.9% did not perform any physical exercise. Average days experiencing pain was 32.9 (SD: 2.8) and 80% were undergoing previous pharmacological treatment. The quality of life utility index after 3 months was 1.6 points (95% CI: 0.54-2.71) higher in the intervention group. The pain score on the VAS was 0.16 points (95% CI: 0.80-0.48) lower in the intervention group. The health professional explained 10.4% of the reduction in pain observed on the VAS throughout the medical visits.ConclusionAcupressure applied in addition to usual practice appeared to improve cervical pain in the long term. The effectiveness of this technique was partially explained by the health professional that trained the participants on technique application.Trial registration number:NCT01855893.
