Polycystic ovary syndrome

2016

Polycystic ovary syndrome (PCOS) affects 5-20% of women of reproductive age worldwide. The condition is characterized by hyperandrogenism, ovulatory dysfunction and polycystic ovarian morphology (PCOM) - with excessive androgen production by the ovaries being a key feature of PCOS. Metabolic dysfunction characterized by insulin resistance and compensatory hyperinsulinaemia is evident in the vast majority of affected individuals. PCOS increases the risk for type 2 diabetes mellitus, gestational diabetes and other pregnancy-related complications, venous thromboembolism, cerebrovascular and cardiovascular events and endometrial cancer. PCOS is a diagnosis of exclusion, based primarily on the p…

Pili Annulati Coincident with Alopecia Areata, Autoimmune Thyroid Disease, and Primary IgA Deficiency: Case Report and Considerations on the Literatu…

2012

Pili annulati is a rare autosomal dominant hair disorder clinically characterized by a pattern of alternating bright and dark bands of the hair, the bright bands appearing dark if observed by transmitted light. This pattern is due to the periodic occurrence of air-filled cavities along the hair cortex which scatter and reflect the light while precluding its transmission. A susceptibility region, including a possibly responsible Frizzled gene, has been mapped to the telomeric region of chromosome 12q, although a specific mutation has not been identified. The condition has sometimes been observed in concurrence with alopecia areata, and in this paper we report a case in whom the concomitant s…

Nanoliposomas de baicalina y berberina en el tratamiento de afecciones cutáneas

2020

Las enfermedades cutáneas afectan a un gran número de personas. Entre ellas destacan la psoriasis, una enfermedad crónica inflamatoria, y el vitíligo, caracterizada por la despigmentación gradual de la piel. Asimismo, la alopecia representa una de las patologías con mayor impacto sobre la calidad de vida de los pacientes. Las tres tienen en común la ausencia de un tratamiento eficaz. Una de las posibles estrategias terapéuticas que pueden contribuir a resolver este problema sería la administración por vía tópica, ya que presenta una serie de ventajas frente a otras vías. En la presente Tesis Doctoral se propone la administración por vía tópica de productos naturales como coadyuvantes en el …

Feature characterization of scarring and non-scarring types of alopecia by multiphoton microscopy (Conference Presentation)

2018

Treatment and management of alopecia are highly determined by an accurate diagnosis, which can be challenging due to the lack of methods to properly visualize hair follicles. Current standard diagnosis is based on dermoscopy for non-scarring alopecia and scalp biopsy for scarring types of alopecia. Dermoscopy can be inconclusive, while biopsy is a painful procedure. In this study, we used a clinical tomograph based on multiphoton microscopy (MPM) to non-invasively image the scalp of 5 healthy subjects and of 12 patients affected by non-scarring alopecia (androgenetic and areata) and scarring alopecia (frontal fibrosing). MPM is capable of non-invasive in vivo imaging of follicular structure…

5‐Alpha reductase inhibitors in androgenetic alopecia: Shifting paradigms, current concepts, comparative efficacy, and safety

2020

Androgenetic alopecia (AGA) is a multifactorial disease that carries a significant psychological burden with it. Dihydrotestosterone, the main pathogenic androgen in AGA, is produced by conversion of testosterone, which is catalyzed by the 5-alpha reductase (5-AR) isoenzyme family. Finasteride and dutasteride are inhibitors of these enzymes. Finasteride, which is a single receptor 5-alpha reductase inhibitor (5-ARI), acts by blocking dihydrotestosterone (DHT). Dutasteride, a dual receptor DHT blocker, has a higher potency than its predecessor, finasteride. This review corroborates the evidence of superiority of dutasteride over finasteride, and its comparable safety profile concerning ferti…

Allergic contact dermatitis in patients with frontal fibrosing alopecia: An international multi‐center study

2020

Frontal fibrosing alopecia (FFA) mainly affects the anterior hairline and eyebrows and its etiology and associated factors remain obscure. The aim of this study was to evaluate the allergic contact dermatitis with patch test in patients with FFA. In this prospective study, 20 patients with FFA and 24 age and sex-matched healthy individuals were evaluated with patch testing. Diagnosis was made histologically, clinically and based on dermoscopic findings. Demographic data, age of onset, disease duration and FFA severity index are evaluated in all patients. Positive patch test reaction to one or more allergen was observed in 65% of patients while it was 37.5% in control group (P = .003). There…
