ABSTRACT

Abstract Female androgenetic alopecia or female-pattern hair loss (FPHL) is highly prevalent and has a great impact on the quality of life. The treatment is a routine challenge in dermatological practice, as many therapeutic options have a limited level of evidence and often do not meet patients expectations. Lack of knowledge of the pathogenesis of the hair miniaturization process and the factors that regulate follicular morphogenesis restricts the prospect of innovative therapies. There is also a lack of randomized, controlled studies with longitudinal follow-up, using objective outcomes and exploring the performance of the available treatments and their combinations. Topical minoxidil, which has been used to treat female pattern hair loss since the 1990s, is the only medication that has a high level of evidence and remains the first choice. However, about 40% of patients do not show improvement with this treatment. In this article, the authors critically discuss the main clinical and surgical therapeutic alternatives for FPHL, as well as present camouflage methods that can be used in more extensive or unresponsive cases.

ABSTRACT

Abstract In this work, polystyrene-b-poly (acrylic acid) (PS-b-PAA) nanovesicles were coated by modified chitosans aiming at studying its physicochemical parameters. The chitosan (CS) was chemically modified to add hydrophilic and/or hydrophobic groups, obtaining three modified chitosans. The PS-b-PAA nanovesicles were obtained by organic (1,4-dioxane) cosolvent method in water, resulting in nanovesicles with less than 150 nm of diameter (polydispersibility index - PDI at 90° = 0.106), measured by dynamic light scattering (DLS) and transmission electron microscopy (TEM), and negative zeta potential (-37.5 ± 3.2 mV), allowing the coating of its surface with oppositely charged polysaccharides, such as the CS and the modified chitosans. The coating process was made by mixing the colloidal suspensions with the CS and the modified chitosans at specific ENT#091;CS-xENT#093;/ENT#091;PS-b-PAAENT#093; ratios (0.001 to 1.0 wt %) and measuring the change in size and surface charge by DLS and zeta potential. Upon reaching maximum adsorption, the zeta potential parameter was positively stabilized (+26.7 ± 4.1 mV) with a hydrodynamic diameter slightly longer (< 200 nm of diameter). The encapsulation efficiency (EE) of minoxidil, quantified by capillary electrophoresis, was 50.7%, confirming their potential as drug delivery carriers and the coating process showed the possibility of controlling the surface charge nature of these nanovesicles

ABSTRACT

Background: Androgenetic alopecia is the most common cause of chronic hair loss. The FDA approved treatment for male androgenetic alopecia are Finasteride and Minoxidil. But many patients do not respond to these medications. Microneedling is a recent modality that releases several growth factors and enhances penetration of minoxidil, thereby promoting hair growth.Methods: 60 patients, aged 21-40 years, with androgenetic alopecia were divided into 2 groups. In group A, patients were subjected to microneedling twice monthly, immediately followed by application of topical 5% minoxidil solution over the scalp and then 1 ml twice daily. In group B, patients were treated with application of 1ml of topical 5% minoxidil solution over the scalp twice daily. The results were evaluated based on patient’s and physician’s assessment based on the standardized 7-point evaluation scale.Results: Patients in group A showed statistically significant improvement (p value<0.05) compared to group B. Headache and erythema were the most common side effects encountered in both the groups.Conclusions: Microneedling with 5% minoxidil is a safe, simple and cost-effective modality and is a promising treatment option for patients with androgenetic alopecia. It showed much better results when compared to use of topical 5% minoxidil solution alone.

ABSTRACT

Resumen El derrame pericárdico es una acumulación excesiva de líquido en el espacio pericárdico, el cual se ha asociado al empleo crónico de minoxidil desde principios de su uso clínico; este es formulado comúnmente a pacientes con hipertensión arterial de difícil control y con enfermedad renal crónica asociada, por su efecto vasodilatador arterial y poco efecto sobre la circulación venosa. Se expone el caso de un paciente quien presentó clínica sugestiva de derrame pericárdico, el cual fue confirmado por imágenes (rayos X, tomografía y ecocardiografía) y quien además se encontraba en tratamiento de hemodiálisis crónica por enfermedad renal crónica secundaria a síndrome nefrótico. En la literatura existen algunos reportes de casos similares, pero no hay estudios con datos concluyentes que permitan establecer un porcentaje claro de asociación ni la causa de esta enfermedad. Con este reporte de caso se busca aumentar la sospecha diagnóstica de esta asociación para que otros clínicos tengan este posible diagnóstico en mente, una vez se hayan descartado otras etiologías adicionales y puedan suspender a tiempo la medicación a fin de evitar desenlaces catastróficos como el taponamiento pericárdico.


Abstract Pericardial effusion is an excessive accumulation of fluid in the pericardial space and has been associated with the long-term use of minoxidil from the beginning of its clinical use. It is commonly prescribed to patients with difficult to control arterial hypertension and associated chronic kidney disease due to it arterial vasodilator effects and little effect of the venous circulation. A case is presented on a patient who had a clinical picture suggestive of a pericardial effusion, which was confirmed by imaging tests (X-ray, tomography, and cardiac ultrasound). She was also on long-term haemodialysis treatment due to chronic kidney disease secondary to a nephrotic syndrome. There are reports of similar cases in the literature, but there are no studies with conclusive data that may help to establish a clear percentage association or the cause of the disease. This case report seeks to increase the diagnostic suspicion of this association so that other clinicians may have this possible diagnosis in mind, once they have ruled out any other. They can then stop the medication on time in order to prevent catastrophic outcomes like pericardiac tamponade.

ABSTRACT

Background: Androgenetic alopecia is the commonest type of alopecia affecting over half of men and women. Low-level light therapy is a new technique for stimulating hair growth in both genders. Aims: To overcome the shortcomings of previous epidemiological studies and a lack of controlled clinical trials on the subject, this study compared the effectiveness of adding low-level light therapy to minoxidil topical solution in the treatment of androgenetic alopecia in patients presenting to two skin clinics in Isfahan, Iran during 2014–2015. Materials and Methods: This clinical trial included 50 patients aged 17–45 presenting to Khorshid and Alzahra educational centers and skin diseases research center for androgenetic alopecia during 2014–2015. The patients were randomly divided into a control and a case group. The case group received topical minoxidil 5% solution plus low-level light therapy twice per day. The control group was given the same topical solution and a laser comb system that was turned off to act as a placebo. Changes in patients' hair density and diameter and its overall regrowth as well as their satisfaction with the treatment were assessed at months 0 (baseline), 3, 6, 9 and 12. Results: The percentage of recovery from androgenetic alopecia and the patients' satisfaction with their treatment were significantly higher in the case group compared to the control group. The patients' mean hair density and diameter were found to be higher in the case group after the intervention compared to the control group. Limitations: The study limitations included patient compliance, small sample size, patient insight due to novelty of the method and clinical judgement. Conclusion: As a new method of treatment, low-level light therapy can help improve the percentage of recovery from androgenetic alopecia and increase patients' satisfaction with their treatment.

ABSTRACT

Hypertension is a global health problem. Antihypertensives are the mainstay of treatment for hypertension. Some of them were accidentally found to be useful in alopecias and infantile hemangiomas and have now become standard treatment for these conditions as well. Antihypertensives are also being studied for other dermatological indications, where they have shown promising efficacy. This review focuses on the dermatological indications for antihypertensives, discussing the drugs that have been tried, as well as their efficacy, dosage, duration of therapy, and adverse effects.

ABSTRACT

BACKGROUND: A variety of agents have been used to treat female pattern hair loss (FPHL), including topical minoxidil, topical 17α-estradiol, oral anti-androgen agents, and mineral supplements. Compared with these single agent regimens, combination therapies could be a better therapeutic option in expectation of superior treatment outcome. OBJECTIVE: This study was designed to determine the efficacy of a combination therapy consisting of topical 0.025% 17α-estradiol and 3% minoxidil in Korean patients with FPHL. METHODS: Therapeutic efficacy was evaluated in 34 women who applied topical 0.025% 17α-estradiol and 3% minoxidil once daily for more than 6 months. Phototrichogram analysis was performed before and after therapy. The efficacy was evaluated with respect to total hair count, hair caliber (as assessed by phototrichogram analysis), and photographic assessment. RESULTS: Total hair count and hair caliber both increased from baseline to 6 months in patients treated with the combination therapy of topical 0.025% 17α-estradiol and 3% minoxidil (p<0.001). Photographic assessment also revealed significant disease improvement, thus supporting the therapeutic efficacy. CONCLUSION: A combination therapy consisting of topical 0.025% 17α-estradiol and 3% minoxidil can be tried as an effective treatment for FPHL.

ABSTRACT

Androgenetic alopecia (AGA) is a common form of hair loss that usually occurs in the third or fourth decades of life in men, with later onset in women. AGA does rarely occur, however, in the pediatric population. Adolescent AGA is pattern hair loss occurring in boys and girls between 12 and 18 years of age. We herein report the case of a 16-year-old girl with a 5-year history of diffuse hair loss on the crown. Her father had a history of AGA, and the hair pull test was negative. Sex hormone levels and thyroid function test were within the normal range. Phototrichogram analysis revealed diffuse hair thinning over the frontal and vertex areas, and the percentage of vellus hair was higher on the vertex than the occiput. We diagnosed the patient with adolescent AGA. She was prescribed 3% topical minoxidil, and improvement was visible on the clinical photograph and phototrichogram after 2 years of treatment.

ABSTRACT

Abstract Rare cases of hypertrichosis have been associated with topically applied minoxidil. We present the first reported case in the Brazilian literature of generalized hypertrichosis affecting a 5-year-old child, following use of minoxidil 5%, 20 drops a day, for hair loss. The laboratory investigation excluded hyperandrogenism and thyroid dysfunction. Topical minoxidil should be used with caution in children.

ABSTRACT

Alopecia androgenética é condição de importante impacto psicológico. Tratamentos clínicos apresentam respostas variáveis e exigem cuidados por longos períodos, fator que diminui as chances de aderência. Microagulhamento associado ou não à injeção de minoxidil é uma nova modalidade de tratamento. Relatam-se os casos de dois pacientes do sexo masculino, de 30 e 44 anos, com resposta parcial satisfatória a quatro sessões de microagulhamento com minoxidil e três sessões de microagulhamento isolado respectivamente, utilizando máquina de tatuagem e técnica de microinfusão de medicamentos pela pele (MMP®).


Androgenetic alopecia is a condition with an important psychological impact. Clinical treatments present variable responses and require care for long periods, a factor that decreases the chances of adhesion. Microneedling with or without minoxidil injection is a new treatment modality. This study reports cases of two male patients, aged 30 and 44 years, with satisfactory partial response to four sessions of microneedling with minoxidil and three sessions of microneedling alone, using a tattoo machine and microinfusion of drugs into the skin technique.

ABSTRACT

BACKGROUND: Previous published clinical studies have demonstrated the positive effects of electrical stimulation (ES) on hair growth. Minoxidil (MXD) enhances hair growth by prolonging the anagen phase of hair follicles. MXD is used to promote hair growth in androgenetic alopecia. OBJECTIVE: To investigate the combined effect of ES and MXD on cultured human dermal papilla cells (hDPCs). METHODS: To investigate the combined effect of ES and MXD on cultured human dermal papilla cells (hDPCs). Methods: hDPCs were electrically stimulated with different parameter settings of alternating current. Electrically stimulated hDPCs were incubated in an MXD medium, after which cell proliferation was measured using an MTT assay. Ki-67 and β-catenin expressions were measured by immunofluorescence assay. In addition, Wnt/β-catenin pathway-related gene expressions were measured by real time-PCR, and phosphorylated ERK and AKT protein levels were measured by western blot assay. RESULTS: The combination of 8 V-1 MHz ES and MXD treatment promoted hDPC proliferation effectively, compared with that in the control, ES alone, or MXD alone treatment groups. The immunofluorescence assay showed that the expression of Ki-67 and β-catenin significantly increased in the combined treatment group. Most of the Wnt/β-catenin pathway-related gene expressions increased more with combined treatment than with the control, ES alone, or MXD alone treatments. However, there were no significant differences in the expression levels of phosphorylated ERK and AKT among the treatment groups. CONCLUSION: ES combined with MXD treatment had a synergistic effect on the proliferation of hDPCs. This might be through the synergistic activation of the Wnt/β-catenin pathway.

ABSTRACT

BACKGROUND: Algae have traditionally been used for promotion of hair growth. Use of hair regrowth drugs, such as minoxidil, is limited due to side effects. The aim of this study was to examine a mixture of Saccharina japonica and Undaria pinnatifida (L-U mixture) on hair growth and to compare the promoting effect of hair growth by a 3% minoxidil and a L-U mixture. METHODS: To evaluate the hair growth-promoting activity, saline, 50% ethanol, 3% minoxidil, and the L-U mixture were applied 2 times a day for a total of 14 days on the dorsal skin of C57BL/6 mice after depilation. Analysis was determined by using a high-resolution hair analysis system, real-time polymerase chain reaction, and H&E staining. RESULTS: On day 14, the hair growth effect of the L-U mixture was the same as that of the 3% minoxidil treatment. The L-U mixture significantly (P<0.05) stimulated hair growth-promoting genes, as vascular endothelial growth factor (VEGF) and insulin-like growth factor -1. Increase of VEGF was observed in the L-U mixture group compared with minoxidil and the negative control. In contrast, the L-U mixture suppressed the expression of transforming growth factor-β1, which is the hair loss-related gene. In histological examination in the L-U mixture and minoxidil groups, the induction of an anagen stage of hair follicles was faster than that of control groups. CONCLUSIONS: This study provides evidence that the L-U mixture can promote hair growth in mice, similar to the effect from minoxidil, and suggests that there is potential application for hair loss treatments.
