Article Synopsis
  • The study aimed to assess how different toothpastes with specific fluoride combinations affect the enamel's resistance to erosion caused by acidic substances like orange juice.
  • Bovine enamel-dentin discs were treated with various dentifrices after undergoing cycles of acid exposure and rehydration, with their surface hardness and roughness measured to evaluate the results.
  • The findings revealed that the toothpaste containing stannous fluoride (SnF) showed significantly better preservation of enamel hardness and smoothness compared to other formulations after five days of exposure, suggesting its potential benefits for people at risk of dental erosion.

Background: Migraine may be accompanied by several cervical musculoskeletal dysfunctions, for example an altered performance on the Craniocervical Flexion Test (CCFT). However, CCFT measurement properties are still unclear in patients with migraine.

Objectives: To determine intra- and inter-examiner reliability, construct validity, standard measurement error (SEM), and minimal detectable change (MDC) of the CCFT in patients with migraine.

Article Synopsis
  • Offset analgesia (OA) reflects how the body modulates pain but its mechanisms are still unclear, involving both central and peripheral factors, particularly A-delta fibers.
  • This study tested the effects of blocking A-fiber conduction using a compression method on healthy participants to see how it influenced OA responses to heat stimuli.
  • Results showed that while OA was present before, during, and after the blockade, no significant effect of A-fiber blockade was detected, suggesting that central mechanisms might play a more critical role in OA than peripheral A-fibers.

Article Synopsis
  • Myofascial trigger point therapy (MTrP) is used for pain relief, but its mechanisms, including central pain modulation (CPM), are not fully understood; this study explores their potential correlation in healthy individuals.
  • The study involved 94 participants subjected to heat and pressure stimuli to assess pain responses before and after MTrP and CPM interventions, systematically measuring mild and intense pressure on specific areas.
  • Results indicated a significant correlation between the pain relief from MTrP and CPM, suggesting overlapping mechanisms; the relationship was stronger with more intense stimulation.

The species is a multidrug-resistant yeast capable of causing systemic and lethal infections. Its virulence and increase in outbreaks are a global concern, especially in hospitals where outbreaks are more recurrent. In many cases, monotherapy is not effective, and drug combinations are opted for.

Importance: It is usually assumed that an individual's classification as a patient or a healthy person is determined by the presence or absence of disease, but little is known about whether the mere awareness of being a patient or a healthy control can play an important role for reporting outcomes.

Objective: To investigate whether assignment to the role of a patient or a healthy control has an effect on patient-reported outcomes.

Design, Setting, And Participants: This single center, double-blind, 3-group randomized clinical trial included consecutive patients from a tertiary headache clinic based at a single center in Germany who were invited to participate between October 2019 and June 2023.

Research suggests that pain negatively affects body image, and body image may also influence reported pain levels. This review aims to summarize the literature on differences in body image distortion between individuals with pain compared to pain-free individuals. The review was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses 2020 statement and an a priori preregistered protocol.

Background: Complications following arthroscopic anterior cruciate ligament reconstruction (ACLR) are rare, but injuries to the popliteal artery can occur. Popliteal pseudoaneurysms are a potential complication and can cause significant morbidity if not diagnosed and treated promptly.

Cases Description: We describe the cases of two patients who developed nerve injuries following arthroscopic ACLR, with subsequent diagnosis of a popliteal pseudoaneurysm.

Background: Cutaneous allodynia is highly prevalent among migraineurs and is associated with a poor prognosis. The Allodynia Symptom Checklist (ASC-12) is a comprehensive questionnaire to identify the presence and severity of allodynia. Our aim was to translate and adapt the ASC-12 to German and evaluate its measurement properties.

Offset analgesia (OA) is observed when pain relief is disproportional to the reduction of noxious input and is based on temporal contrast enhancement (TCE). This phenomenon is believed to reflect the function of the inhibitory pain modulatory system. However, the mechanisms contributing to this phenomenon remain poorly understood, with previous research focusing primarily on painful stimuli and not generalizing to nonpainful stimuli.

is an emerging yeast of worldwide interest due to its antifungal resistance and mortality rates. The aim of this study was to analyse the in vitro and in vivo antifungal activity of a nanoemulsion loaded with amphotericin B (NEA) against planktonic cells and biofilm of clinical isolates belonging to four different clades. In vivo assays were performed using the model to analyse antifungal activity and histopathological changes.

Obesity is an inflammatory disease associated with secondary diseases such as kidney disease, which can cause lipotoxicity, inflammation and loss of organ function. Polyunsaturated fatty acids act in the production of lipid mediators and have anti-inflammatory characteristics. In this work, the objective was to evaluate renal histopathology in obese mice and the effects of treatment with capybara oil (CO) (5000 mg/kg/day for 4 weeks).

Background: Migraine has been associated with balance dysfunction, more pronounced in patients with aura and chronic migraine. Also, it has been suggested that balance deficits are progressive through the migraineurs lifetime.

Objective: To analyze the one-year progression of balance parameters and clinical parameters associated with balance in female patients with and without migraine.

Background: Migraine patients may present with both cervical and balance dysfunctions. The neck plays an important role in balance by providing substantial proprioceptive input, which is integrated in the central nervous system and influences the balance control systems. Whether balance and neck dysfunctions are associated in patients with migraine is still to be explored.
