Correction to: Photobiomodulation versus light-emitting diode (LED) therapy in the treatment of temporomandibular disorder: study protocol for a randomized, controlled clinical trial.

After publication of our article [1] we became aware that several sections of text in our Methods section were copied from a previously published article [2].

Photobiomodulation therapy (PBMT) on acute pain and inflammation in patients who underwent total hip arthroplasty-a randomized, triple-blind, placebo-controlled clinical trial.

When conservative treatments fail, hip osteoarthritis (OA), a chronic degenerative disease characterized by cartilage wear, progressive joint deformity, and loss of function, can result in the need for a total hip arthroplasty (THA). Surgical procedures induced tissue trauma and incite an immune response. Photobiomodulation therapy (PBMt) using low-level laser therapy (LLLT) and/or light-emitting diode therapy (LEDT) has proven effective in tissue repair by modulating the inflammatory process and promoting pain relief.

Photobiomodulation versus light-emitting diode (LED) therapy in the treatment of temporomandibular disorder: study protocol for a randomized, controlled clinical trial.

Background: Temporomandibular disorder (TMD) is described as a subgroup of orofacial pain with a set of signs and symptoms that involve the temporomandibular joint, masticatory muscles, ears, and neck. TMD can occur unilaterally or bilaterally and approximately 70% of the population is affected with at least one sign. The disorder progresses with orofacial pain, muscle pain involving the masticatory and cervical muscles, joint noises (clicks and pops), joint block, mandibular dysfunction, and headache.

[Streptococcus pneumoniae meningitis in children. Case records 1985 - 2003].

Acute bacterial meningitis and sepsis are the most severe among invasive diseases due to Streptococcus pneumoniae, particularly in pediatric age, and present a high risk of mortality and neurologic sequelae. S. pneumoniae is a major worldwide pathogen in children.

Subclinical hypothyroidism and hyperprolactinemia.

The authors have studied 25 women aged 22 to 26 years with a diagnosis of prolactinemia moderately increased in primary sterility. Among 25 women under observation, 7 (28%) showed a hormone picture of subclinic hypothyroidism. In fact the evaluation of TSH after stimulation with TRH showed a curve typical of the subclinic hypothyroidism.
