Adverse Reactions Associated with Dermal Fillers in the Oral and Maxillofacial Region: A Venezuelan Experience.

Background: Dermal facial fillers are increasingly popular. Published reports on the clinical and histopathologic characteristics related to adverse reactions to dermal fillers in the facial region have been relatively well documented. This study adds to the literature on adverse reactions to injected filler in the oral and maxillofacial region in a South American population.

Congenital Melanotic Macule of the Tongue: Report of Two Cases and Literature Review.

Background: Congenital melanotic macule of the tongue (CMMT) has been described as a distinct entity, despite its unknown etiology. However, the diagnosis and management of affected newborns may challenge clinicians and pediatric dentists.

Methods: We document here the clinicopathological findings of two additional cases of CMMT.

International registry of dermatological manifestations secondary to COVID-19 infection in 347 Hispanic patients from 25 countries.

Background: The infection by coronavirus disease 2019 (COVID-19) has been associated with multiple cutaneous manifestations, although characterization of them in Hispanic patients with darker skin phototypes is lacking. The objective of this study is to characterize the clinical dermatological manifestations associated with COVID-19 infection in cases with few or without general symptoms in patients from Latin America.

Methods: Cross-sectional study using a questionnaire that was made for health professionals (physicians with a specialty in dermatology) to investigate dermatological lesions associated with COVID-19 infection in patients from 25 countries of Latin America.

Oral manifestations associated with antimalarial therapy in patients with systemic lupus erythematosus.

Introduction: Lupus erythematosus (LE) is an autoimmune disease often treated with antimalarial drugs. The prolonged use of chloroquine and hydroxychloroquine can cause hyperpigmentation in the skin, oral mucosa and retinal pigment epithelium, which in turn can trigger toxicity in this epithelium, which in some cases causes vision loss. The objective of the present work was to establish the association between the presence of oral pigmented macules by antimalarial and secondary retinal toxicity.

Odontogenic cutaneous sinus tracts due to infection with nontuberculous mycobacteria: a report of three cases.

Background: Soft tissue or skin infections due to nontuberculous mycobacteria (NTM) have been reported frequently and are mostly associated with trauma or cosmetic interventions like plastic surgery. However, infection with NTM as a result of a dental procedure have rarely been described and the lack of clinical suspicion and a clear clinical manifestation makes diagnosis challenging.

Case Presentation: We report on three patients with a facial cutaneous sinus tract of dental origin, due to an infection with respectively Mycobacterium fortuitum, M.

The CILAD, a model of an international dermatologic society, united by geographic, linguistic, and cultural nexus.

The Ibero Latin American College of Dermatology, CILAD, the largest dermatologic organization in the region, was established in 1948 during the course of the V International Congress of Leprosy held in Havana, Cuba. Constituted in its beginning with fewer than 100 dermatologists from nine countries, its growth has been exponential, reaching now around 4000 members spread throughout Latin America, the Iberian Peninsula, and other regions of the world. In recent years, academic activity has been intense, such as the development of several institutional programs, like its community health care program, designed for geographic areas lacking dermatologic care in the Latin American region.

Psoriasis in Latin America.

During the last few decades, management of psoriasis has changed worldwide, owing to a better understanding of its pathophysiology and the introduction of new treatments. As experts in the field of dermatology, specialists from Latin America collaborated to develop this review and further provide an update on the current state of psoriasis management in Latin America. With the goal of summarizing the latest information on psoriasis in most countries in Latin America, we conducted a literature search to obtain relevant articles published in the medical/scientific literature in Latin American countries over the last 10 years; in addition, we completed a questionnaire comprised of 20 questions on important issues related to psoriasis.

The diagnosis of two cases of cutaneous ulcer caused by infection with Mycobacterium haemophilum: direct identification in a clinical sample by polymerase chain reaction-restriction endonuclease analysis.

Background: Mycobacterium haemophilum was first recovered from subcutaneous lesions of a patient with Hodgkin's disease. Because of its special growth requirements (it grows at 30-32 degrees C and requires iron-supplemented medium), the organism cannot be isolated using routine culture techniques for other mycobacteria. Only a few developed countries have reported infection with this mycobacterium.

[Soft-tissue infections due to non-tuberculous mycobacteria following mesotherapy. What is the price of beauty].

Introduction: Mesotherapy is widely used In Latin America for cosmetic purposes, particularly in obese individuals. We describe the clinical and epidemiological characteristics, microbiological diagnosis, treatment and follow-up of patients from Caracas (Venezuela) with soft tissue infection caused by non-tuberculous mycobacteria following mesotherapy.

Methods: Between March 2002 and December 2003, we evaluated 49 cases of skin and soft tissue infection following mesotherapy.
