Consequences of COVid-19 in Latin American dentists in the first year of the pandemic, the period prior to vaccination campaigns.

Objectives: The aim of this investigation was to assess the impact of the COVID-19 pandemic on dentists in Latin America during the initial year of the outbreak, specifically within the timeframe preceding vaccination campaigns. This study determined the various facets in which dentists were affected and exactly what proportion of them was harmed. Methods: A comprehensive 33 question survey was distributed across 19 Latin American countries after the first year of the COVID-19 pandemic's presence in the region. Results: There was an absence of statistically significant differences in responses among the surveyed countries in Latin America, with the exception of four questions out of the total 33. Some relevant findings of Latin American were: one in three dental professionals experienced discrimination based on their occupation. Concurrently, three out of four dentists reported initiating new activities to lessen discomfort. Notably, 8.63 % of respondents sought assistance from a psychologist or psychiatrist, while 17.71 % resorted to the consumption of psychoactive substances within the first year of the pandemic.Furthermore, 7.28 % of the professionals indicated that they still had not obtained all the necessary personal protective equipment for their work and 92.05 % disclosing that they personally financed these essential resources. A certain percentage of dentists stated that the quality of care decreased due to the implementation of the new safety measures (40.03 %) or due to their own feelings during patient interactions (23.11 %). Lastly, 38.85 % of dentists contemplated leaving the profession. Conclusions: The impact of the COVID-19 pandemic on dentists was decidedly adverse, manifesting both in personal and professional fields, despite the diverse measures undertaken by these professionals to mitigate its effects.

Exploring the Relationships Between Altered Body Perception, Limb Position Sense, and Limb Movement Sense in Complex Regional Pain Syndrome.

Chronic pain is often accompanied by patient-reported distorted body perception and an altered kinesthesia (referring to the senses of limb position and limb movement), but the association between these deficits is unknown. The objectives of this study were to assess body perception and the senses of limb position and limb movement in complex regional pain syndrome (CRPS) and to test whether these variables are related to each other and to pain intensity. Thirteen patients with upper limb CRPS (mean pain intensity, 4.2 ± 2.4 out of 10) and 13 controls were recruited. Body perception was self-reported with a questionnaire, and the senses of limb position (task 1) and of limb movement (task 2) were assessed with a robotic system combined with a 2D virtual reality display. The results showed altered kinesthesia in the patients with CRPS compared with controls (all P < .05). Moreover, in the CRPS group, greater pain intensity was associated with lower performance on task 2 (r = -.60; P < .05). Although alterations in participants' sense of limb position and limb movement were associated with each other (r = -.70, P < .01), they were not related to the altered body perception (all P > .26). Therefore, the results suggest that kinesthesia and body perception should be considered and evaluated separately in patients with CRPS. PERSPECTIVE: Senses of limb position and movement rely on sensorimotor integration. Both are altered in complex regional pain syndrome. However, they are not related to the subjective perception of the painful limb, and thus they should be assessed separately in rehabilitation.
