Open-label placebo treatment in chronic low back pain: A randomized controlled trial

This randomized controlled trial was performed to investigate whether placebo effects in chronic low back pain could be harnessed ethically by adding open-label placebo (OLP) treatment to treatment as usual (TAU) for 3 weeks. Pain severity was assessed on three 0- to 10-point Numeric Rating Scales, scoring maximum pain, minimum pain, and usual pain, and a composite, primary outcome, total pain score. Our other primary outcome was back-related dysfunction, assessed on the Roland-Morris Disability Questionnaire. In an exploratory follow-up, participants on TAU received placebo pills for 3 additional weeks. We randomized 97 adults reporting persistent low back pain for more than 3 months' duration and diagnosed by a board-certified pain specialist. Eighty-three adults completed the trial. Compared to TAU, OLP elicited greater pain reduction on each of the three 0- to 10-point Numeric Rating Scales and on the 0- to 10-point composite pain scale (P < 0.001), with moderate to large effect sizes. Pain reduction on the composite Numeric Rating Scales was 1.5 (95% confidence interval: 1.0-2.0) in the OLP group and 0.2 (-0.3 to 0.8) in the TAU group. Open-label placebo treatment also reduced disability compared to TAU (P < 0.001), with a large effect size. Improvement in disability scores was 2.9 (1.7-4.0) in the OLP group and 0.0 (-1.1 to 1.2) in the TAU group. After being switched to OLP, the TAU group showed significant reductions in both pain (1.5, 0.8-2.3) and disability (3.4, 2.2-4.5). Our findings suggest that OLP pills presented in a positive context may be helpful in chronic low back pain.

La rieducazione posturale globale (RPG) e efficace in soggetti con low back pain cronico aspecifico? Una revisione sistematica della letteratura

Background: La lombalgia (o Low Back Pain -LBP) è una condizione multifattoriale e complessa che rappresenta una delle principali cause di disabilità al mondo. Si definisce “cronica” quando persiste per più di 12 settimane e “aspecifica” quando non risultano identificabili i meccanismi eziologici alla base della patologia. La Rieducazione Posturale Globale (RPG) è una metodica fisioterapica il cui scopo è quello di allungare i muscoli accorciati, migliorare la contrazione dei muscoli antagonisti e controllare la respirazione, migliorando la morfologia corporea. Obiettivo: Valutare, nei soggetti con LBP cronico aspecifico, l’efficacia della RPG rispetto a dolore, disabilità, articolarità, forza muscolare, qualità della vita, prevenzione delle recidive. Metodi: Sono state consultate le seguenti banche dati biomediche: PubMed, Cochrane Library, Scopus, SportDiscus e PEDro, nel periodo tra il 1° maggio e il 30 settembre 2022. Sono stati inclusi studi randomizzati controllati (RCTs) e studi sperimentali non randomizzati (NRSI) in lingua italiana, inglese o francese, senza restrizione inerente all’anno di pubblicazione. Un solo autore indipendente ha estratto i dati. Per valutare il rischio di bias degli studi inclusi sono stati impiegati il Cochrane Rob2 tool per gli RCT e il ROBINS-I per i NRSI. Risultati: 7 studi (5 RCT e 2 NRSI) hanno soddisfatto i criteri di eleggibilità e sono stati inclusi. Si è riscontrata una bassa qualità metodologica: cinque studi con alto rischio di bias e due studi con moderato rischio di bias. In tutti i trials la metodica RPG si è mostrata efficace nel ridurre dolore e disabilità, soprattutto a breve termine; tuttavia non ci sono sufficienti prove per affermarne la superiorità rispetto ad altre terapie. Conclusioni: La RPG è in grado di ridurre il dolore e la disabilità in soggetti con LBP cronico aspecifico nel breve termine. Studi futuri con maggiore validità interna sono necessari per conferire maggior certezza alle evidenze.

Contraction of the pelvic floor muscles during abdominal maneuvers

Objective: To determine whether voluntary abdominal muscle contraction is associated with pelvic floor muscle activity. Design: Pelvic floor muscle activity was recorded during contractions of the abdominal muscles at 3 different intensities in supine and standing positions. Setting: Research laboratory. Participants: Six women and 1 man with no histories of lower back pain. Interventions: Not applicable. Main Outcome Measures: Electromyographic activity of the pelvic floor muscles was recorded with surface electrodes inserted into the anus and vagina. These recordings were corroborated by measurements of anal and vaginal pressures. Gastric pressure was recorded in 2 subjects. Results: Pelvic floor muscle electromyography increased with contraction of the abdominal muscles. With strong abdominal contraction, pelvic floor muscle activity did not differ from that recorded during a maximal pelvic floor muscle effort. The pressure recordings confirmed these data. The increase in pressure recorded in the anus and vagina preceded the pressure in the abdomen. Conclusions: In healthy subjects, voluntary activity in the abdominal muscles results in increased pelvic floor muscle activity. The increase in pelvic floor pressure before the increase in the abdomen pressure indicates that this response is preprogrammed. Dysfunction of the pelvic floor muscles can result in urinary and fecal incontinence. Abdominal muscle training to rehabilitate those muscles may be useful in treating these conditions.

Behcet`s disease associated with celiac disease: a very rare association

There are common findings between Beh double dagger et`s disease (BD) and celiac disease (CD); however, association in the same patient is a rarity. We relate the third case in the literature of this overlap in a 40-year-old woman with history of obstipation since her childhood. She also presented asymmetric polyarthralgia, loss of weight, anemia, oral recurrent aphthas (> 3/year) and genital ulcerations, inflammatory lower back pain, bowel bleeding and abdominal colic. Afterwards, she presented episodes of erythema nodosum, superficial thrombophlebitis, pseudofolliculitis and aseptic meningitis, thus fulfilling criteria for BD. Due to persistence of the digestive complaints, a gastrointestinal endoscopy was performed. The biopsy showed chronic duodenitis with intraepithelial lymphocytosis, crypt hyperplasia, and villous atrophy. Endomysial antibody was positive. She fulfilled the diagnosis criteria for CD; a gluten-free diet was applied with clinical improvement. Ascertaining whether pathogenic mechanisms are common in these two conditions requires further investigation.
