RESUMO

Follicular unit hair extraction (FUE) is effective for hair restoration but is less successful on scarred tissue due to reduced vascularity and altered tissue architecture. Stem cell therapy can enhance tissue regeneration, possibly improving FUE outcomes on scarred tissue. This study investigated the impact of stem cell therapy prior to FUE on scarred tissue. Sixty patients with scalp scars from trauma or previous surgeries were divided into two groups. Group A (n = 30) received autologous stem cell therapy followed by FUE, while Group B (n = 30) underwent FUE without prior stem cell treatment. Autologous stem cells were harvested from patients' adipose tissue and injected into the scarred area four weeks before FUE. Outcomes were assessed at 3-, 6-, and 12-months post-transplantation, focusing on hair density, graft survival rate, and patient satisfaction. Histological examinations evaluated tissue regeneration. Group A showed significantly higher hair density (mean increase of 45%) and graft survival rates (87%) compared to Group B (mean increase of 25%, graft survival rate of 60%) at all follow-up points (P < 0.05). Histological analysis revealed enhanced neovascularization and reduced fibrosis in the stem cell-treated group, with 70% more new blood vessels and 50% less fibrotic tissue compared to the control group. Patient satisfaction scores were higher in Group A (average score of 8.5 out of 10) versus Group B (6.0), indicating better aesthetic outcomes and reduced scar visibility. Pre-treatment with autologous stem cell therapy significantly improved FUE effectiveness on scarred tissue, enhancing graft survival, hair density, and patient satisfaction. Further research is recommended to optimize this therapeutic strategy.

RESUMO

Post-combustion alopecia presents a complex medical challenge with implications spanning dermatological and psychiatric disorders. The use of hair transplantation has proven to be a significant improvement for this condition. However, the current management involves various techniques, each with advantages and disadvantages. Progressive skin expansions, surgical scar reduction, and skin grafts containing hair follicles yield unsatisfactory aesthetic outcomes and have limited applicability as a first-line treatment for fire victims. So far, follicular unit extraction (FUE) has proven to be one of the most versatile procedures in such cases, having the potential to restore a natural anatomical profile closely resembling the pre-traumatic appearance that led to the traumatic alopecia. Additionally, it contributes to the improvement of associated psychiatric comorbidities, facilitating proper social reintegration and enhancing overall quality of life. This report focuses on a case of post-combustion alopecia and severe facial distortion due to third-degree burns resulting in severe psychiatric comorbidities, which benefited from a proper social reintegration and improvement of the quality of life after three consecutive sessions of FUE for scalp and eyebrow hair.

RESUMO

The human papilloma virus (HPV) infection, caused by a ubiquitous virus typically transmitted through the direct contact of infected organs, either through the skin or mucosa, is the most common sexually transmitted infection, placing young women at a high risk of contracting it. Although the vast majority of cases spontaneously clear within 1-2 years, persistent HPV infection remains a serious concern, as it has repeatedly been linked to the development of multiple malignancies, including cervical, anogenital, and oropharyngeal cancers. Additionally, more recent data suggest a harmful effect of HPV infection on pregnancy. As the maternal hormonal environment and immune system undergo significant changes during pregnancy, the persistence of HPV is arguably favored. Various studies have reported an increased risk of adverse pregnancy outcomes among HPV-positive women, with the clinical impact encompassing a range of conditions, including preterm birth, miscarriage, pregnancy-induced hypertensive disorders (PIHD), intrauterine growth restriction (IUGR), low birth weight, the premature rupture of membranes (PROM), and fetal death. Therefore, understanding the mechanisms employed by HPV that negatively impact pregnancy and assessing potential approaches to counteract them would be of interest in the quest to optimize pregnancy outcomes and improve child survival and health.

RESUMO

Endometriosis represents a frequently diagnosed gynecological affliction in the reproductive timespan of women, defined by symptoms ranging from pelvic pain to infertility. A complex interplay between the genetic profile, hormonal activity, menstrual cyclicity, inflammation status, and immunological factors define the phenotypic presentation of endometriosis. To date, imaging techniques represent the gold standard in diagnosing endometriosis, of which transvaginal ultrasonography and magnetic resonance imaging bring the most value to the diagnostic step. Current medical treatment options for endometriosis-associated infertility focus on either stimulating the follicular development and ovulation or on inhibiting the growth and development of endometriotic lesions. Techniques of assisted reproduction consisting of superovulation with in vitro fertilization or intrauterine insemination represent effective treatment alternatives that improve fertility in patients suffering from endometriosis. Emerging therapies such as the usage of antioxidant molecules and stem cells still need future research to prove the therapeutic efficacy in this pathology.
