Dietas populares y su impacto en la piel. Una revisión narrativa / Popular Diets and Skin Effects: A Narrative Review

Se han popularizado diversas dietas para perder peso, incrementar la capacidad física y para el manejo de múltiples enfermedades crónicas: cardiovasculares, neurológicas o cutáneas. Destacan la dieta cetogénica y el ayuno intermitente, con resultados prometedores en la medicina tradicional y deportiva. Además, la dieta mediterránea se ha consolidado como una forma de alimentación de impacto positivo muy significativo en la salud. Otras dietas populares son la dieta «paleo», la dieta vegana y la libre de gluten. La dieta cetogénica, el ayuno intermitente y la dieta mediterránea aportan resultados favorables en dermatosis inflamatorias como la psoriasis, dermatitis atópica, hidradenitis supurativa o acné. La dieta mediterránea podría actuar también como factor protector para el desarrollo de algunas neoplasias cutáneas. En este artículo presentamos una revisión del papel de diversas dietas populares en el manejo de dermatosis. (AU)

Numerous diets for losing weight, building strength, and managing a range of cardiovascular, neurologic, and skin diseases have become popular in recent years. The ketogenic diet and intermittent fasting in particular have shown promising results in clinical and sports medicine. The Mediterranean diet, in turn, is widely recognized for its numerous health benefits. Also popular are the paleo diet and vegan and gluten-free diets. Positive effects on inflammatory conditions, such as psoriasis, atopic dermatitis, hidradenitis suppurativa, and acne, have been observed in patients who practice intermittent fasting or follow ketogenic or Mediterranean diets. This last choice may also protect against certain skin cancers. We review the role of several popular diets in the management of skin disorders. (AU)

Sun exposure, a relevant exposome factor in acne patients and how photoprotection can improve outcomes.

BACKGROUND: Acne pathophysiology includes a complex interaction among inflammatory mediators, hyperseborrhea, alteration of keratinization and follicular colonization by Propionibacterium acnes. AIMS: To describe the impact of the exposome on acne and how photoprotection can improve outcomes. METHODS: A narrative review of the literature was carried out; searches with Google Scholar and Pubmed from January 1992 to November 2022 were performed. The keywords used were "acne," "sunscreens," "photoprotection," "cosmetics," "cosmeceuticals," "pathogenesis," "etiology," "exposome," "sunlight," "stress," "lack of sleep," "diet," "postinflammatory hyperpigmentation," "pollution," "exposome," "ultraviolet radiation," and "visible light." RESULTS: Environmental factors such as solar radiation, air pollution, tobacco consumption, psychological stress, diverse microorganisms, nutrition, among others, can trigger or worsen acne. Solar radiation can temporarily improve lesions. However, it can induce proinflammatory and profibrotic responses, and produce post-inflammatory hyperpigmentation and/or post-inflammatory erythema. While photoprotection is widely recommended to acne patients, only four relevant studies were found. Sunscreens can significantly improve symptomatology or enhance treatment and can prevent post-inflammatory hyperpigmentation. Furthermore, they can provide camouflage and improve quality of life. Based on acne pathogenesis, optimal sunscreens should have emollient, antioxidant and sebum controlling properties. CONCLUSIONS: The exposome and solar radiation can trigger or worsen acne. UV light can induce post-inflammatory hyperpigmentation/erythema, and can initiate flares. The use of specifically formulated sunscreens could enhance adherence to topical or systemic therapy, camouflage lesions (tinted sunscreens), decrease inflammation, and reduce the incidence of post-inflammatory hyperpigmentation/erythema.

Tratamiento mediante suplementación oral o fármacos sistémicos del envejecimiento cutáneo. Revisión narrativa de la literatura / Oral Supplementation and Systemic Drugs for Skin Aging: A Narrative Review

El envejecimiento cutáneo está influido por factores intrínsecos y extrínsecos y múltiples mecanismos patogénicos están involucrados. Los tratamientos utilizados en la actualidad son sobre todo tópicos o son procedimientos mínimamente invasivos. La evidencia sobre la utilidad de la terapia sistémica es limitada: los estudios son en su mayoría de pequeño tamaño, de reducida duración, incluyen a mujeres de manera mayoritaria, la metodología de evaluación es heterogénea y no hay parámetros consensuados de respuesta clínica relevante. Además, los suplementos o fármacos sistémicos no están exentos de efectos adversos. El colágeno hidrolizado oral y el ácido hialurónico oral son bien tolerados y múltiples ensayos clínicos muestran que pueden mitigar algunos signos de envejecimiento cutáneo. La isotretinoína oral en dosis bajas es otra alternativa, pero con un mayor potencial de efectos adversos. Múltiples suplementos, como vitaminas, flavonoides, diversos extractos de plantas y oligoelementos, presentan escasa evidencia clínica. El futuro del manejo del envejecimiento cutáneo parece ser el tratamiento con agentes senolíticos o senomórficos dirigidos específicamente contra células cutáneas senescentes. (AU)

Skin aging is influenced by intrinsic and extrinsic factors and involves multiple pathogenic mechanisms. The most widely used treatments are topical products and minimally invasive procedures. Evidence on the benefits of systemic therapy is limited for several reasons: Reliance on mostly small and predominantly female samples, short study durations, methodologic heterogeneity, and a lack of consensus on which outcome measures are clinically relevant. Furthermore, systemic drugs and oral supplements are not without adverse effects. Oral hydrolyzed collagen and oral hyaluronic acid are well tolerated, and numerous clinical trials show they can mitigate some signs of skin aging. Low-dose oral isotretinoin is another option, but it has a higher risk of adverse effects. Evidence is lacking on the effects of the many dietary supplements on offer, such as vitamins, flavonoids, plant extracts, and trace elements. The future of skin aging management would appear to lie in the use of senolytic and senomorphic agents targeting senescent cells in the skin. (AU)

La hidroxicloroquina como fármaco fundamental en dermatología y su papel controvertido en la COVID-19 / Hydroxychloroquine: An Essential Drug in Dermatology and Its Controversial Use in COVID-19

La hidroxicloroquina es un antimalárico con acción inmunomoduladora, antiinflamatoria, antibacteriana y antiviral. Posee un buen perfil de seguridad y puede ser utilizada en niños, en mujeres embarazadas o durante la lactancia, y no produce inmunosupresión. La retinopatía es uno de sus efectos adversos más temidos y requiere controles regulares. La hidroxicloroquina es un fármaco esencial en dermatología, utilizado ampliamente con buenas tasas de respuesta clínica tanto como un tratamiento de primera línea en el lupus eritematoso, como en múltiples dermatosis autoinmunes/inflamatorias como liquen plano, erupción polimorfa lumínica, porfiria cutánea tarda, granuloma anular y sarcoidosis, entre otras. Durante el año 2020 fue prescrita a gran escala como profilaxis y tratamiento de la infección producida por el coronavirus SARS-CoV-2 (COVID-19). El aumento de la utilización de hidroxicloroquina produjo serias dificultades para su obtención e incluso desabastecimiento. En metaanálisis recientes se ha concluido que la hidroxicloroquina no es efectiva para el tratamiento de esta patología y se desaconseja su prescripción (AU)

Hydroxychloroquine is an antimalarial drug with immunomodulatory, anti-inflammatory, antibacterial, and antiviral properties. It has a good safety profile, can be used in children and in pregnant and breastfeeding women, and does not suppress the immune system. Regular screening for retinopathy, one of the drug's most feared adverse effects, is necessary. Hydroxychloroquine is a widely used, essential drug in dermatology. Clinical response rates are good in lupus erythematous, where it is a first-line therapy, as well in numerous autoimmune/inflammatory diseases, including lichen planus, polymorphic light eruption, porphyria cutanea tarda, granuloma annulare, and sarcoidosis. In 2020, it was widely prescribed both to prevent and to treat COVID-19 caused by SARS-CoV-2. Its increased use led to serious supply shortages and in some cases stocks were entirely depleted. Recent meta-analyses have concluded that hydroxychloroquine is ineffective against COVID-19 and have advised against its use (AU)

68Ga-PSMA-11 PET/CT in patients with occult biochemical recurrence of prostate carcinoma and negative 18F-Choline PET/CT. Preliminary assessment of its clinical use.

OBJECTIVE: To assess the clinical usefulness of 68Ga-PSMA PET/CT studies in patients with occult biochemical recurrence of prostate carcinoma, with negative or inconclusive radiologic and 18 F-Choline PET/CT imaging studies. MATERIAL AND METHODS: Retrospective descriptive study. The first 14 patients with a history of prostate carcinoma, treated with curative intent and presenting suspicion of biochemical recurrence with low PSA values (<3 ng/mL) were selected. Imaging studies, prostate ultrasound, pelvic CT and/or MRI were negative, and all of them had a negative or inconclusive 18F-Choline PET/CT. All patients were referred to 68 Ga-PSMA-11 PET/CT. PROTOCOL: Dose 2.2 M Bq/kg. 20 mg furosemide at start. PET/CT images from skull base to proximal third of thighs at 60 min, and late images at 3 h if needed. RESULTS: The 68 Ga-PSMA-11 PET/CT was able to localize the occult biochemical recurrence in 9 of the 14 patients (64.2%), and it affected the therapeutic attitude in all of them. Four patients (28.5%) obtained a negative or inconclusive 68 Ga-PSMA-11 PET/CT and continued under vigilant approach with PSA controls and imaging studies according to the clinical guidelines. These patients had the lowest PSA values (less than 1 ng/mL). One of the 68 Ga-PSMA-11 PET/CT studies was inconclusive, reporting the presence of a doubtful right iliac adenopathy. CONCLUSION: 68 Ga-PSMA-11 PET/CT allows an early diagnosis, with low PSA values, of occult biochemical recurrence of prostate carcinoma, even in patients with negative 18 F-Choline PET/CT.

Ga-PSMA-11 PET/TC en la recidiva bioquímica oculta del carcinoma de próstata, con 18F-Colina PET/TC negativa. Valoración preliminar de su uso clínico / Ga-PSMA-11 PET/CT in patients with occult biochemical recurrence of prostate carcinoma and negative 18F-Choline PET/CT. Preliminary assessment of its clinical use

Objetivo: Valorar la utilidad de los estudios 68Ga-PSMA PET/TC en la práctica clínica de los pacientes con recidiva bioquímica oculta de carcinoma de próstata, con estudios de imagen radiológicos y 18F-Colina PET/TC negativos o no concluyentes.Material y métodosobservacional retrospectivo y de exactitud diagnóstica. Se seleccionaron los primeros 14 pacientes con antecedentes de carcinoma de próstata, tratados con intención curativa y que presentaban sospecha de recidiva bioquímica con valores bajos de antígeno prostático específico (PSA) (< 3 ng/mL). Los estudios de imagen, ecografía prostática, tomografía computarizada (TC) y/o resonancia magnética (RM) pélvica eran negativos, y todos ellos tenían un 18F-Colina PET/TC negativo o no concluyente. Se derivó a todos los pacientes para realizarse un 68Ga-PSMA-11 PET/TC. Protocolo: Dosis 2,2 MBq/kg, 20 mg de furosemida en el minuto 0. Imágenes PET/TC desde calota craneal hasta el tercio proximal de muslos a los 60 min, e imágenes tardías a las tres horas, si precisara.ResultadosEn nueve de los 14 pacientes (64,2%) el 68Ga-PSMA-11 PET/TC consiguió localizar la recidiva bioquímica oculta, y en todos ellos hubo cambios en la actitud terapéutica. En cuatro de los 14 pacientes (28,5%) el 68Ga-PSMA-11 PET/TC resultó negativo o no concluyente, se prosiguió con la actitud vigilante con controles de PSA y estudios de imagen, según los protocolos habituales. Estos pacientes presentaban los valores más bajos de PSA (inferiores a 1 ng/mL). Uno de los estudios 68Ga-PSMA-11 PET/TC fue no concluyente, informándose la presencia de una dudosa adenopatía iliaca derecha. (AU)
