A narrative review of dermatologic protocols for primary care medical service trips in Latin America and the Caribbean

A qualitative narrative review of protocols for women's health on short-term medical missions in Latin America and the Caribbean

BACKGROUND

Women's health conditions are commonly encountered on short-term medical missions (STMMs) in Latin America and the Caribbean. There have been no previous attempts to describe women's health protocols used by volunteer clinicians. This qualitative study aimed to describe areas of agreement between unpublished women's health protocols from different North American STMM organizations and assess their concordance with published WHO guidelines.

METHODS

A systematic web search was used to identify North American STMM sending organizations. Clinical protocols were downloaded from their websites and organizations were contacted to request protocols that were not published online. The protocols obtained were summarized, analysed thematically and compared to existing WHO guidelines.

RESULTS

Of 225 organizations contacted, 112 (49.8%) responded and 31 of these (27.7%) had clinical protocols, of which 20 were obtained and analysed. Nine (45%) discussed sexually transmitted infections, six (30%) discussed pelvic inflammatory disease, two (10%) discussed prenatal care and two (10%) discussed menstrual disorders. None were the product of systematic literature searches and most were not referenced.

CONCLUSIONS

To avoid ineffective treatment and related harms to women, volunteer clinicians would benefit from the adaptation and distribution of guidelines for STMMs that are based on existing WHO guidance and acceptable to clinicians, patients and organizations.

Analysis on the pathogenic fungi in patients with superficial mycosis in the Northeastern China during 10 years

This study analyzed the infection of superficial mycosis and the relationship between the distribution characteristics of pathogenic fungi and age, time and sex in Northeast China in the past 10 years. We would like to provide a theoretical basis for the diagnosis and treatment of related diseases. From December 2008 to December 2018, 5,374 superficial mycoses from Northeast China were selected. The fungal species were identified by fungal microscopy, fungal culture, and species identification. Besides, the relationship between sex, age, time and the distribution of superficial mycosis and pathogenic fungi was analyzed. Among the 5,374 patients, the top three infections were tinea pedis (n=1,538, 28.62%), tinea cruris (n=1,018, 18.94%) and tinea corporis (n=938, 17.45%). The top three pathogens were Trichophyton rubrum (n=2,849, 48.65%), Trichophyton mentagrophytes (n=947, 16.14%) and Candida spp. (n=804, 13.70%). The main pathogenic fungi were dermatophytes. The age group with the highest incidence of tinea capitis was children (n=372, 6.92%). The highest incidence rate of tinea pedis was in 31-69-year adults (n=905, 16.84%); Malassezia mainly affects young people aged 15-30. Yeast and mold mostly invade the elderly patients >60 years old. The incidence of tinea cruris, tinea pedis and tinea corporis in male patients was higher than that in female patients. The incidence of onychomycosis in female patients was higher than that in male patients (P<0.05). The isolation rate of Candida, Mold, Microsporum canis, Malassezia and Sporothrix increased year by year, while that of Trichophyton rubrum, Trichophyton mentagrophyte, Trichophyton schoenleinii and Epidermophyton floccosum decreased. From December 2008 to December 2018, dermatophytes were the main pathogens of superficial mycosis in Northeast China. The distribution of disease species and pathogenic fungi varied in different gender, age and time.

Screening and Intervention for Skin Cancer in the Galapagos

OBJECTIVE

This study aimed to assess the general dermatological needs and correlation of tentative skin cancer screening diagnoses with histopathological confirmation in the highly sun-exposed locals of the Galapagos Islands.

METHODS

An institutional review board-approved prospective study was performed at Blanca's House, a nonprofit surgical volunteer organization, free clinics in the Galapagos. After consent, a 40-item modified SPOTme-inspired questionnaire was completed. Partial or total body skin examinations were conducted by board-certified dermatologists. Board-certified plastic and general surgeons performed excisional biopsies on suspicious lesions. Individuals younger than 18 years, and non-Spanish or non-English speakers were excluded.

RESULTS

A total of 273 patients were included in the study, of which 202 reported skin concerns. Benign nevi (n = 76), seborrheic keratosis (n = 42), melasma (n = 19), actinic keratosis (n = 16), acne (n = 15), eczema (n = 13), fungal infections (n = 12), seborrheic dermatitis (n = 5), and psoriasis (n = 5) were most commonly identified.Twelve patients (4.4%) had presumptive skin cancer after screening. Six of 8 biopsies confirmed cancer (group 1), 2 declined a biopsy and 2 were unresectable. Seven basal cell carcinomas and one squamous cell carcinoma were excised with clear margins. A right lower eyelid melanoma was diagnosed and subsequently treated in the United States where invasive melanoma with a Breslow thickness of 0.3 mm was found.Compared with the noncancer group (group 2: n = 265), group 1 had significantly higher likelihood of reporting having seen a dermatologist (P = 0.02), taking any medications (P = 0.0001), having blonde or red hair (P = 0.01), having blue or green eyes (P < 0.0001), and having used indoor tanning equipment (P < 0.0001). Group 1 was also more likely to report 4 or more blistering sunburns (P = 0.08), which approached significance. When evaluated by a dermatologist, group 1 was significantly more likely to be classified as "high risk" for developing cancerous lesions (P < 0.0001) compared with group 2.

CONCLUSIONS

Skin concerns in the Galapagos included benign and malignant conditions. There is a need for dermatological care in this medically underserved population. This modified SPOTme-inspired skin cancer questionnaire, confirmed by histology, is a useful tool in identifying high-risk patients and detecting skin cancer in international communities that would have otherwise experienced delays in diagnosis or treatment.
