The aim of the study was to summarize and review the evidence for the efficacy and safety of adipose-derived stem cells (ADSCs) and platelet-rich plasma (PRP) for the treatment of vulvar lichen sclerosus (LS).
The study group included eleven female patients aged 18-77 years with a diagnosis of lichen sclerosus. Basic therapy consisted in the application of clobetasol in the first month and then once a day for the following two months. Then, clobetasol was recommended once a week until full resolution of the symptoms.
Mucinous metaplasia of the vulva (MMV) is a histopathologic finding that has been reported previously in only 3 patients and needs to be distinguished from vulvar extramammary Paget disease. We report 3 additional instances of MMV associated to Zoon vulvitis and vulvar lichen sclerosus et atrophicus. Histochemical and immunohistochemical studies were performed on biopsies from erythematous and erosive vulvar lesions of 3 women aged 64, 80 and 84 years, with features of Zoon vulvitis (2 cases) and lichen scl...
Lichen sclerosus is a chronic inflammatory dermatological condition with a predilection for the anogenital area.
Balanitis xerotica obliterans (BXO), or penile lichen sclerosus, is a progressive sclerosing inflammatory dermatosis of the glans penis and foreskin. It is associated with significant morbidity and may result in impaired urinary and sexual function. It was initially described by Stuhmer in 1928, named after its pathological features, and is considered the male equivalent of vulvar lichen sclerosis (LS). The etiology of BXO is uncertain; however, autoimmune disease, local trauma, and genetic and infective ca...
Microvascular assessment has become increasingly used in gynecology to better understand the pathophysiology of various vulvar conditions and to study sexual function. Alteration in blood perfusion of the vulvar area has been observed using laser technologies in women with provoked vestibulodynia (PVD), the leading cause of vulvar pain. However, no studies have thus far investigated the reliability of an agreement between lasers for evaluating vulvar blood perfusion.
Vulvar intraepithelial neoplasia (VIN) is a precursor to vulvar squamous cell carcinoma and is defined histopathologically by the presence of atypia. VIN has been classified into two types: usual vulvar intraepithelial neoplasia (uVIN), which is also referred to as a vulvar high-grade squamous intra-epithelial lesion (HSIL), and differentiated VIN (dVIN). The former is associated with chronic infection by sub-types of the human papilloma virus (HPV), whereas dVIN is HPV-independent and frequently associated...
Lichen sclerosus (LS) is a chronic, inflammatory genital skin condition affecting men, women and children. Long-term complications include loss of normal anatomy from scarring, and malignant transformation. Uncertainties exist about the cause, diagnosis and management of LS. For example, the aetiology is contested; evidence suggests that chronic irritation by occluded urine is important in males, however, autoimmune mechanisms are proposed in females. Genetic associations are suggested in both sexes. Existi...
Insights into the pathophysiology of urethral stricture disease due to lichen sclerosus: comparison of pathologic markers in lichen sclerosus induced strictures versus non-lichen sclerosus induced strictures.
OBJECTIVE To evaluate the pathophysiology of lichen sclerosus (LS) and non-LS urethral stricture disease (USD) by comparing protein expression related to inflammation, cell cycle disruption, oxidative stress, hormone receptor status and infection. METHODS Tissue samples were collected from urethral strictures of 81 patients undergoing urethroplasty. Clinical and demographic data was obtained from chart review. After identifying areas pathognomonic for LS, a tissue microarray was created with cores from each...
Dowling-Degos disease (DDD) is a rare autosomal-dominant genodermatosis with limited treatment possibilities. Although the efficacy of ablative laser therapy has been reported, we sought to examine the efficacy of fractional versus full ablative laser therapy in a female patient with DDD in a split-side report. We treated the lesions on the right side of the patient's upper abdomen with an ablative fractional CO laser and the lesions on the left side of the upper abdomen with a full ablative Er:YAG laser (e...
To evaluate a dual-phase protocol for vaginal ablative Erbium:YAG laser treatment in pelvic floor medicine.
The flashlamp-pumped, solid-state, pulsed, mid-infrared, holmium:YAG laser (λ = 2120 nm) has been the clinical gold standard laser for lithotripsy for over the past two decades. However, while the holmium laser is the dominant laser technology in ureteroscopy because it efficiently ablates all urinary stone types, this mature laser technology has several fundamental limitations. Alternative, mid-IR laser technologies, including a thulium fiber laser (λ = 1908 and 1940 nm), a thulium:YAG laser (λ = 2010 n...
Surgically lifting and scraping, mitomycin C, fibrin glue, Nd:YAG laser, hydrogel ocular sealant, and amniotic membrane patch are the reported methods for treating epithelial ingrowth after laser in situ keratomileusis (LASIK). Here we report the management of a rare case of recalcitrant epithelial ingrowth using a combined scraping/laser ablation that occurred after LASIK.
Low-fluenced 2940-nm erbium (Er):yttrium-aluminium-garnet (YAG) resurfacing elicits ablative photothermal tissue reactions confined to the uppermost parts of the epidermis.
The purpose of this prospective analysis was to evaluate the efficacy of erbium-substituted yttrium aluminum garnet (Er:YAG) laser compared with that of conventional surgery, regarding the long-term outcome of nondysplastic oral leukoplakias (OL).
The aim of this case report was to evaluate the treatment of vulvar lymphangioma applying photodynamic therapy (PDT). Patient aged 61 years old complained of burning, local pain, which caused intense discomfort for over 5 years. She had developed vulvar edema, papules and vesicles that draining clear exudate, in which histological finding confirmed the vulvar lymphangioma. A red diode laser (Photon Lase III, DMC, Brazil) was applied locally after a 2% methylene blue aqueous solution (MB) in the vulvar targe...
A new treatment for androgenetic alopecia (AGA) is 1,550-nm erbium-glass (Er:Glass) fractional laser. The wound healing process associated with this treatment is believed to be due to the stimulation of hair regrowth. Both the Wingless-related integration site (Wnt) proteins and insulin-like growth factor 1 (IGF-1) are important molecules that promote new hair growth.
We report the demonstration of a 2824 nm passively cooled erbium-doped fluoride fiber laser delivering a record average output power of 41.6 W in continuous-wave operation. The splice-less cavity is based on intra-core fiber Bragg gratings written directly in the active erbium-doped fluoride fiber, which is bidirectionally pumped at 980 nm to reduce heat load. To the best of our knowledge, this result is the highest average output power achieved with a mid-infrared fiber laser. The long-term performance ...
To evaluate the effect of erbium: yttrium aluminium garnet laser conditioning bond strength of orthodontic brackets on porcelain surfaces.
The biosynthesis of two polyketides, atranorin and fumarprotocetraric acid, produced from a lichen-forming fungus, Cladonia rangiferina (L.) F. H. Wigg. was correlated with the expression of eight fungal genes (CrPKS1, CrPKS3, CrPKS16, Catalase (CAT), Sugar Transporter (MFsug), Dioxygenase (YQE1), CH Transcription factor (CH), Transcription Factor PacC (PacC), which are thought to be involved in polyketide biosynthesis, and one algal gene, NAD-dependent deacetylase sirtuin 2 (AsNAD)), using laser microdisse...
A tunable self-seeded multi-wavelength Brillouin-erbium fiber laser (BEFL) based on a Lyot filter is experimentally demonstrated in this paper. The Lyot filter is constructed by a polarization-dependent isolator (PDI), two polarization controllers (PCs), and a 20-cm-length polarization-maintaining fiber. In this proposed structure, the PDI is used as a polarizer. Due to the periodic filtering characteristics of the Lyot filter, the multi-wavelength output of the laser shows different Brillouin bands by adju...
A 47-year-old white woman presented to our clinic complaining of recalcitrant warts on her trunk and extremities. She had an extensive past medical history including immunodeficiency of unknown origin, pulmonary hypertension, rheumatoid arthritis, and systemic lupus erythematosus, for which she was being treated with chronic immunosuppressive therapy with methylprednisolone and belimumab. The patient had previously failed treatments at an outside facility with liquid nitrogen, trichloroacetic acid, topical ...
