Introduction: Androgenic alopecia is a progressive alteration of the scalp with few treatment options, which motivates the search for new local or systemic medications to control this pathology.
Objective: To evaluate patient tolerance for and identify the action mechanism of the Cellium® GC compound in the treatment of androgenic alopecia.
Methods: Male patients (n = 20) with androgenic alopecia participated in this open prospective study. The compound was used on the scalp twice a day, at home, for 12 con- secutive weeks. Biopsies were carried out before and after treatment to evaluate the alterations in the cutaneous immune response, cellular proliferation and anti-apoptosis activity. Questionnaires were administered to evaluate efficacy and patient satisfaction.
Results: Nineteen patients completed the study, with an average satisfaction of 8.3 out of 10. Immunohistochemical analyses of scalp biopsies showed a significant increase in the cutaneous immune response after treatment: 73.9% increase in CD1A+ Langerhans cells (p = 0.003, t paired test), 41.7% increase in the cellular proliferation marker Ki-67+ (p = 0.012), and an 89% increase in BCL-2+ anti apoptotic proteins (p = 001). The product was also found to be tolerable and safe.
Conclusions: Cellium® GC improved the skin''''''''s immune defense and the proliferation of keratinocytes, and produced high levels of patient satisfaction in the treatment of androgenic alopecia.

In hair transplants, the donor area can supply only a limited number of follicular units in each procedure. In the treatment of more advanced degrees of baldness, removing both a scalp strip and follicular units, one by one, is an option that allows more units to be harvested in a single session, thus providing a better density and coverage of the bald area. This article describes a technique called Untouched Strip, which, in addition to increasing the number of follicular units with the combined procedure, preserves the donor area for a possible future transplant.

Introduction: Telogen effluvium is a chronic progressive alopecia of multifactorial etiology. Nutritional deficiency-sometimes subclinical-can trigger it. Objective: To evaluate the influence of a nutritional supplementation at physiological doses in patients with telogen effluvium. Methods: The supplementation of nutrients in food doses was carried out in 60 female patients for 180 days. Results: There was a significant improvement (p <0.05) in hair loss, which was confirmed by digital phototrichogram, where there was a significant increase in anagen hairs and reduction of telogen hairs. Conclusion: The present study demonstrated that in cases of telogen effluvium without an apparent cause, the replenishment of nutrients related to the hair cycle has a significant benefit in the regression of the picture as soon as after three months of treatment.

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.

Introduction: Androgenetic alopecia is the most common type of hair loss in men and women. Nowadays, medication based treatments are the most frequently used nevertheless they yield poor results. More recently, the use of lasers has been proposed to treat this condition. At the same time, the infiltration of medications in the scalp has also been growing as a therapeutic option, although there are few scientific studies on this treatment modality.
Objective: To evaluate the results of using 1,550nm Erbium-Glass laser associated with the injection of active principles (minoxidil, finasteride, growth factors and a vitamin complex) for the treatment of male and female androgenetic alopecia.
Methods: A retrospective study was carried out with patients with androgenetic alopecia diagnosis, who underwent monthly sessions of the proposed combination therapy. The results were evaluated by means of comparative photographs taken before and after the treatment period and the assessment of the patients' opinion.
Results: Sixty-two patients were treated with 3 to 14 sessions; 48.39% of patients had mild improvement, and 46.77% had significant improvement. The vast majority (96.77%) was satisfied with the treatment. The patients who were very satisfied with the outcomes underwent a greater number of sessions (more than six, on average).
Conclusions: The association of 1,550nm Erbium-Glass laser therapy with the injection of active principles in the scalp is an effective and safe option for the treatment of androgenetic alopecia.

Alopecia areata is a chronic condition of hair follicles and nails with unknown etiology, which causes hair loss. It emerges in several clinical types, with the diffuse form, where there is acute and diffuse hair loss, being atypical. It is generally accepted that there is a T-cell mediated, organ-specific autoimmune base in alopecia areata and studies indicate that the autoantigen is associated with melanocytes. The authors of the present paper report the case of a patient who had the diffuse form of alopecia areata, with preservation of the gray hair strands

O queratoacantoma (QA), apesar de frequente na prática diária, é um tumor que gera questionamentos. O aspecto mais intrigante associa-se à sua posição no limite entre malignidade e benignidade. A abordagem do tumor, bem como sua classificação, é controversa. Na definição da conduta, é importante levar em conta o potencial de transformação para carcinoma espinocelular. Desse modo, a excisão cirúrgica é a terapia de escolha, sempre que possível. Algumas situações merecem atenção adicional, como a imunossupressão associada. Neste artigo, relatamos um caso de QA gigante em um paciente com síndrome da imunodeficiência adquirida tratado com cirurgia micrográfica de Mohs.

Frontal fibrous alopecia is a primary lymphocytic scarring alopecia that is difficult to control, with a perifollicular lichenoid infiltrate marking its histology. Since its description in 1994 by Kossard, there has been an increase in cases reported worldwide. This article reports two cases that underwent incisional biopsies with longitudinal and transverse sections in areas presenting higher disease activity and reviews some aspects of this dermatosis. It also addresses the suspicion of a possible relationship with the application of botulinum toxin – a question already raised by other authors but with no established confirmation.

This study conducted a systematic review of studies on the relationship between androgenic alopecia and metabolic syndrome. We performed a comprehensive review of databases including PubMed, Web of Knowledge, Google Scholar, Scopus, and Embase, and extracted relevant articles published from 2010 to 2018. The case reports, review articles, or studies lacking full-text articles were excluded. We examined nine studies for the meta-analysis step. The results showed a significant relationship between alopecia and metabolic syndrome (OR = 2.81; CI 95% = 2.16-3.66; I2 = 73%; P = 0.0003). There is a significant correlation between androgenic alopecia and metabolic syndrome.

Anagen effluvium (AE) is a hair growth disorder that occurs due to a disturbance in the hair follicle cycling. The most common cause of AE is alopecia areata (AA). Autoimmune diseases like AA may develop after drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome and are usually long-standing conditions. We report the case of a 17-year-old woman who developed a severe and abrupt AE after DRESS syndrome with a full and rapid recovery after two months of topical minoxidil.

A patient with dissecting folliculitis of the scalp who did not respond to antibiotic therapy received four monthly sessions of intradermal administration of 100 IU of botulinum toxin A. Four months after treatment, a complete recovery of the affected area of the patient's scalp was observed. A biopsy taken from the affected area showed the presence of Staphylococcus lugdunensis and Staphylococcus aureus resistant to erythromycin. Botulinum toxin A had no effect on the viability or biofilm production of the Staphylococcus strains, indicating that the healing effect of the toxin was associated with the host response alone.
