Localizacao de covas de trabalhadores indicam que monumentos foram construidos com mao-de-obra livre, e nao escrava.Tumbas dao 'pista' sobre piramides do Egito LASER E SUAS UTILIZACOESAgora entendo porque meus clientes que estao tratando a calvicie/alopecia, relatam que estao se sentindo bem e que nao tem sentido dores que antes estavam incomodando muito. Encontrei esse artigo nas minhas pesquisas.Terapia com LASER e eficaz contra dor cervical Um estudo recente publicado em uma das maiores revistas de medicina (The Lancet) confirma atraves de uma metaanalise que a terapia com LASER melhora a dor cervical, a dor na nuca. Foram analisados 16 estudos que incluiram no total 820 pacientes. Tanto dor cervical aguda quanto cronica se mostraram melhores apos o tratamento com a terapia com laser de baixa potencia. Os efeitos colaterais da terapia com LASER saosemelhantes aos niveis achados com o grupo placebo, ou seja, minimos. A terapia com LASER e eficaz para dor cervical aguda e cronica e sem efeitos colaterais significantes. Como pacientes com cefaleias, dores de cabeca, enxaqueca apresentam frequentemente dor cervical associada, e bem possivel que a terapia com LASER seja tambem eficaz para o tratamento da enxaqueca.Este artigo foi comentado pelo Dr Mario Peres, medico neurologista, pos-doutorado naThomas Jefferson University na area das cefaleias.Veja o resumo do artigo em ingles:Efficacy of low-level laser therapy in the management of neck pain: a systematic review and meta-analysis of randomised placebo or active-treatment controlled trialsRoberta T Chow MBBS, Mark I Johnson PhD, Rodrigo AB Lopes-Martins PhD, Jan M BjordalThe Lancet, Volume 374, Issue 9705, Pages 1897 1908, 5 December 2009Background. Neck pain is a common and costly condition for which pharmacological management has limited evidence of efficacy and side-effects. Low-level laser therapy (LLLT) is a relatively uncommon, non-invasive treatment for neck pain, in which non-thermal laser irradiation is applied to sites of pain. We did a systematic review and meta-analysis of randomised controlled trials to assess the efficacy of LLLT in neck pain.Methods. We searched computerised databases comparing efficacy of LLLT using any wavelength with placebo or with active control in acute or chronic neck pain. Effect size for the primary outcome, pain intensity, was defined as a pooled estimate of mean difference in change in mm on 100 mm visual analogue scale.Findings. We identified 16 randomised controlled trials including a total of 820 patients. In acute neck pain, results of two trials showed a relative risk (RR) of 169 (95% CI 122233) for pain improvement of LLLT versus placebo. Five trials of chronic neck pain reporting categorical data showed an RR for pain improvement of 405 (274598) of LLLT. Patients in 11 trials reporting changes in visual analogue scale had pain intensity reduced by 1986 mm (10042968). Seven trials provided follow-up data for 122 weeks after completion of treatment, with short-term pain relief persisting in the medium term with a reduction of 2207 mm (17422672). Side-effects from LLLT were mild and not different from those of placebo.Interpretation. We show that LLLT reduces pain immediately after treatment in acute neck pain and up to 22 weeks after completion of treatment in patients
