Restoring Severely Atrophic Edentulous Ridge of Mandible Using Self-Expanding Tissue Expander-A Case Report.

This report describes the use of Self Inflating Tissue Expanders (SITEs) to rehabilitate severely atrophic edentulous mandibular ridges, enabling successful bone grafting and implant placement. The treatment resulted in stable and complication-free implants over a seven-year follow-up, demonstrating SITEs' effectiveness in providing sufficient bone volume and soft tissue coverage for dental implants.

Artificial Urinary Sphincter Cuff Downsizing Improves Continence and Patient Satisfaction in Cases of Sub-cuff Atrophy.

PURPOSE: The management of artificial urinary sphincter sub-cuff atrophy remains controversial, and clinical outcomes are underreported. We intend to examine the impact of cuff downsizing in cases of isolated sub-cuff atrophy. MATERIALS AND METHODS: We reviewed our prospectively collected, institutionally approved quality improvement database for this study from 2011 to 2022. Institutional Review Board approval was obtained for the analysis. Sub-cuff atrophy in patients with post-prostatectomy incontinence was diagnosed with a clinical presentation of recurrent urinary leakage, serial pelvic films, cystoscopy, and patient evaluation. Outcomes were assessed with pad use, subjective measures, and American Urological Association Symptom Score scores. RESULTS: During the study interval, 871 encounters for artificial urinary sphincter placement were identified, 229 for revision or replacement, of which cuff downsizing for isolated cases of sub-cuff atrophy occurred in 34. Downsizing took place after a median of 6.5 years after initial artificial urinary sphincter placement. Of the patients, 97% reported subjective improvement and 93% experienced a decrease in daily incontinence pad use, with a mean±SD decrease of 2.2±1.45 pads (P < .01). American Urological Association Symptom Score bother scores decreased from pre-downsizing values by a mean±SD of 1.5±1.4 (P = .01). After a median follow-up of 1.8 years after downsizing, 24 (70.6%) of downsized cuffs remained in place, 2 (5.9%) were further downsized, 2 (5.9%) required replacement for mechanical failure, 4 (11.8%) underwent removal for erosion, and 2 (5.9%) underwent replacement for a herniated pressure regulating balloon. CONCLUSIONS: When diagnosed using objective criteria, cuff downsizing improves continence and patient satisfaction in cases of sub-cuff atrophy.

Reconstruction of Moderately and Severely Atrophic Scalp-A Multicentric Experience in Surgical Treatment of Patients Irradiated for Tinea Capitis in Childhood and Surgical Algorithm.

Background and Objectives: Before the introduction of griseofluvin, the use of X-ray radiation was the treatment of choice for tinea capitis. More than half a century later various types of tumors have been found to be associated with childhood irradiation due to tinea capitis, most commonly cancers of the head and neck, as well as brain tumors. The often unusually aggressive and recurrent nature of these tumors necessitates the need for repeated surgeries, while the atrophic skin with an impaired vascular supply due to radiation often poses an additional challenge for defect reconstruction. We present our experience in the surgical treatment of such patients. Materials and Methods: This is a retrospective cohort study. In this study, 37 patients treated for acquired defects of the scalp with a history of irradiation therapy due to tinea capitis in childhood were included in this study, 24 male and 13 female patients. The mean age at the first appointment was 60.6 ± 7.8, with the youngest included patient being 46 and the oldest being 75 years old. Patients' characteristics, surgical treatment, and complications were analyzed and a reconstructive algorithm was developed. Results: Local flaps were used for reconstruction in 34 patients, direct sutures were used in 10 patients and 20 patients received split-thickness skin grafts for coverage of both primary and secondary defects for reconstruction of flap donor sites. One regional flap and one dermal substitute covered by an autologous skin graft were also used for reconstruction. Complications occurred in 43.2% of patients and were significantly associated with the presence of comorbidities (p = 0.001), aseptic bone necrosis (p = 0.001), as well as skin atrophy in frontal, occipital, and parietal region (p = 0.001, p = 0.042 and p = 0.001, respectively). A significant correlation between major complications and moderate skin atrophy was found only in the parietal region (p = 0.026). Conclusions: Unfortunately, many protocols developed for scalp reconstruction are not applicable in the setting of severe or diffuse scalp skin atrophy associated with high tumor recurrence rate and radiation-induced vascular impairment, such as in tinea capitis patients in Serbia. An algorithm has been developed based on the authors' experience in managing these patients.

Buccally or Lingually Tilted Implants in the Lateral Atrophic Mandible: A Three-Year Follow-Up Study Focused on Neurosensory Impairment, Soft-Tissue-Related Impaction and Quality of Life Improvement.

Background and Objectives: In the severely resorbed posterior mandible, implant placement requires either bone regenerative procedures, subperiosteal implants or short implant placement with drawbacks including morbidity and increased treatment costs and duration. To overcome these inconveniences, some unconventional alternatives have been suggested, such as buccally or lingually tilted implants in the lateral mandible, bypassing the inferior alveolar nerve. The aim of the present retrospective study was to evaluate the three-year survival rate of implants inserted in the posterior atrophic mandible, bypassing the inferior alveolar nerve. The assessment was focused on the occurrence of postoperative complications related to neurosensory impairment and soft tissue impaction, as well as overall improvement in quality of life. Materials and Methods: Patients with severe bone atrophy in the lateral area of the mandible were included in the present study. Only the implants tilted either buccally or lingually to bypass the inferior alveolar nerve were analysed. The relation between peri-implant soft tissue and the healing abutment was assessed and a secondary revision surgery was performed when indicated. The Semmes-Weinstein pressure neurological test was used for qualitative assessment of inferior alveolar nerve function and the Geriatric Oral Health Assessment Index (GOHAI) was used for evaluating Oral-Health-Related Quality of Life (OHRQoL). Results: Fourteen implants were placed in nine patients during the evaluation period. Survival rate was 100%, temporary paraesthesia occurred in one patient and a limited definitive paraesthesia was seen in another patient. Mild or significant discomfort related to soft tissue impaction with healing abutment was observed in six out of nine patients. A statistically significant OHRQoL improvement was observed in all patients. Conclusions: Despite the limited number of patients and observation time, insertion of implants buccally or lingually bypassing the inferior alveolar nerve is a predictive treatment option for patients with severe bone atrophy in the posterior mandible.

Immediate Rehabilitation of the Severely Atrophic Maxilla Using Trans-Sinus Nasal Protocol and Extended Length Subcrestal Angulated Implants. Case Series With 1-Year Follow-Up.

Immediate fixed full-arch rehabilitation of the severely atrophic maxilla eliminates use of a tissue-supported prosthesis during the healing phase and maximizes patient comfort and quality of life. The surgical treatment options available for immediate rehabilitation of the severely atrophic maxilla are dependent on the location and availability of the residual alveolar ridge. When bone is only available in the intercanine region, a graftless approach using tilted distal implants may not provide adequate distance between implants for favorable biomechanics. Subsequently, zygomatic implants are the alternative to provide adequate posterior occlusal support. Use of extended length subcrestal angulated implants offers an additional implant option for the clinician to restore the severely atrophic maxilla immediately. The treatment protocol involves anchorage of the implant fixture to the lateral wall of the nasal bone. The distally tilted implant transverses an augmented sinus cavity and extends to the site of the first permanent molar. The novel implant subcrestal angulation and use of a multi-unit abutment promotes passivity of fit of a full-arch fixed immediate prosthesis. Five clinical case reports from private practice are presented that outline the clinical value of the novel implant design in the rehabilitation of the severely atrophic maxilla. In each case, the use of zygomatic implants would be the only alternative to provide an immediate fixed prosthesis due to the absence of residual alveolar bone in the maxilla premolar and molar regions. The use of extended-length subcrestal angulated (ELSA) implants with straight or angulated multiunit abutments have successfully restored the maxillary arch immediately.

Comparison of Fractional Picosecond 1064-nm Laser and Fractional Carbon Dioxide Laser for Treating Atrophic Acne Scars: A Randomized Split-Face Trial.

BACKGROUND: To date, no studies have compared the fractional picosecond 1064-nm laser (FxPico) and fractional carbon dioxide laser (FxCO2) for the treatment of acne scars. OBJECTIVE: To compare the efficacy and safety between FxPico and FxCO2 for treating facial atrophic acne scars. MATERIALS AND METHODS: Twenty-five Asian patients with mild to moderate atrophic acne scars underwent single sessions of randomized split-face treatment with FxPico and FxCO2. Clinical efficacy was assessed by photographs, skin imaging analysis, and patient satisfaction. The adverse events were recorded on every visit. Skin biopsies were performed immediately and 3 months after treatment. RESULTS: The physician improvement scores for skin texture and atrophy significantly increased on the FxPico sides, but no significant difference was observed between FxPico and FxCO2. Skin imaging also showed significant improvement on both sides for scar volume. Postinflammatory hyperpigmentation (PIH) was not reported on FxPico sides, whereas 6 patients (24%) experienced mild PIH on FxCO2 sides. Immediate post-FxPico skin biopsy revealed laser-induced optical breakdown with photoacoustic columns. Collagen and elastic fibers increased at 3 months after both treatments. CONCLUSION: FxPico was as effective as FxCO2 in treating atrophic acne scars, correlating with evidence of tissue remodeling with more safety profiles.

Lasers in the era of evidence-based medicine.

Transvaginal laser therapies are being increasingly used for a variety of indications, particularly genitourinary syndrome of the menopause and stress urinary incontinence. This article reviews the current data pertaining to the place of these devices in current clinical practice. Whilst there has been a rapid increase in the number of publications over the last few years, many of the studies are of small numbers, short duration, and poor quality and are device-sponsored. The evidence suggests that vaginal laser therapy with either the erbium-doped yttrium aluminum garnet laser (FotonaSmooth®) or the CO2 laser (MonaLisa Touch®) is an effective intervention for the relief of symptoms of vulvovaginal atrophy in symptomatic women. The benefits of three laser treatments appear to last for at least 12 months and the procedure is generally well tolerated, with transient minor discomfort being the most common adverse event. Whilst the vaginal laser certainly has the potential to be an alternative treatment to vaginal estrogens for those groups of women, such as breast cancer patients, who cannot take them, there are still many unanswered questions about the role of vaginal laser therapy in clinical practice, particularly in relation to standard conservative management. The place of vaginal laser therapy in other conditions such as stress urinary incontinence is less clear. The outcomes from several ongoing randomized trials should help to answer some of these questions. In the meantime, the use of vaginal laser devices should be confined to clinical trials.

Extensive Thrombectomy as a Legitimate Strategy in Living Donor Liver Transplantation With Advanced Portal Vein Thrombosis.

Management of portal vein thrombosis (PVT), especially advanced PVT involving the superior mesenteric vein (SMV), in living donor liver transplantation (LDLT) is challenging. There were 514 adults who underwent LDLT between 2005 and 2018 included in this retrospective study, and PVT was observed in 67 (13.0%) patients. The LDLT recipients with PVT were characterized by increased portal pressure at laparotomy (26.1 ± 6.0 versus 24.3 ± 5.9 mm Hg; P = 0.03) and at closure (16.8 ± 3.9 versus 15.6 ± 3.6 mm Hg; P = 0.02), increased operative blood loss (14.6 ± 29.7 versus 5.7 ± 6.3 L; P < 0.01), and decreased 1-year graft survival (83.5% versus 92.8%; P = 0.04). Among the 18 patients with atrophic or vanished portal vein on pre-LDLT computed tomography, significant portal atrophy was actually observed only in 1 (5.6%) patient during LDLT surgery. For advanced PVT (n = 7) involving SMV in era 1, we performed nonanatomical inflow reconstruction using interposition grafts, resulting in significant inflow problems in 4 (57.1%) patients. Thus, for the patients with advanced PVT (n = 4) in era 2, we abandoned nonanatomical reconstruction and applied extensive thrombectomy under ultrasound guidance with secure shunt ligation, resulting in no inflow problems and no graft loss. In conclusion, even for advanced PVT involving SMV, extensive thrombectomy under sonogram guidance followed by anatomical inflow reconstruction and shunt ligation is a legitimate strategy in adult LDLT with PVT.

IUGA committee opinion: laser-based vaginal devices for treatment of stress urinary incontinence, genitourinary syndrome of menopause, and vaginal laxity.

This committee opinion reviews the laser-based vaginal devices for treatment of genitourinary syndrome of menopause, vaginal laxity, and stress urinary incontinence. The United States Food and Drug Administration has issued a warning for unsubstantiated advertising and use of energy-based devices. Well-designed case-control studies are required to further investigate the potential benefits, harm, and efficacy of laser therapy in the treatment of genitourinary syndrome of menopause, vaginal laxity, and stress urinary incontinence. The therapeutic advantages of nonsurgical laser-based devices in urogynecology can only be recommended after robust clinical trials have demonstrated their long-term complication profile, safety, and efficacy.

Treatment to External Labia and Vaginal Canal With CO2 Laser for Symptoms of Vulvovaginal Atrophy in Postmenopausal Women.

Background: Increasingly, women have sought alternatives to traditional options (lubricants, estrogen products, and hormone replacement therapy) for unwelcome vaginal changes of menopause. Objectives: This study evaluated whether a series of three monthly fractional CO2 laser treatments significantly improves and maintains vaginal health indices of elasticity, fluid volume, pH level, epithelial integrity, and moisture. Self-reported symptoms of vaginal atrophy were also measured. Biopsy samples after a series of three treatments were evaluated for histological changes to vaginal canal tissue. Methods: Forty postmenopausal women were treated extravaginally and internally with a fractional CO2 laser. Objective measurements of vaginal health index, as well as subjective measurements of symptoms of vulvovaginal atrophy (VVA), urinary incontinence, and sexual function were reported at baseline. Follow-up evaluations were at one, three, six, and 12 months after the third treatment. Results: Vaginal health index improved significantly after the first treatment and was maintained with mean improvement of 9.6 ± 3.3 (P < 0.001) and 9.5 ± 3.3 (P < 0.001) at the 6- and 12-month follow ups, respectively. Vaginal symptoms of dryness, itching, and dyspareunia improved significantly (P < 0.05) at all evaluations. Histological findings showed increased collagen and elastin staining, as well as a thicker epithelium with an increased number of cell layers and a better degree of surface maturation. Conclusions: Fractional CO2 laser treatments were well tolerated and were associated with improvement in vaginal health and amelioration of symptoms of VVA. Histological changes in the epithelium and lamina propria, caused by fractional CO2 laser treatments, correlated with clinical restoration of vaginal hydration and pH to premenopausal levels.

Liver atrophy and regeneration in noncirrhotic portal vein thrombosis: Effect of surgical shunts.

The goal of the study is to characterize the relationship between portal vein thrombosis (PVT) and hepatic atrophy in patients without cirrhosis and the effect of various types of surgical shunts on liver regeneration and splenomegaly. Patients without cirrhosis with PVT suffer from presinusoidal portal hypertension, and often hepatic atrophy is a topic that has received little attention. We hypothesized that patients with PVT have decreased liver volumes, and shunts that preserve intrahepatic portal flow enhance liver regeneration. Sixty-four adult and pediatric patients with PVT who underwent surgical shunt placement between 1998 and 2011 were included in a retrospective study. Baseline liver volumes from adult patients were compared with standard liver volume (SLV) as well as a group of healthy controls undergoing evaluation for liver donation. Clinical assessment, liver function tests, and liver and spleen volumes from cross-sectional imaging were compared before and after surgery. A total of 40 patients received portal flow-preserving shunts (32 mesoportal and 8 selective splenorenal), whereas 24 received portal flow-diverting shunts (16 nonselective splenorenal and 8 mesocaval). Baseline adult liver volumes were 26% smaller than SLV (1248 versus 1624 cm3 ; P = 0.02) and 20% smaller than the control volumes (1248 versus 1552 cm3 ; P = 0.02). Baseline adult spleen volumes were larger compared with controls (1258 versus 229 cm3 ; P < 0.001). Preserving shunts were associated with significant increase in liver volumes (886 versus 1131 cm3 ; P = 0.01), whereas diverting shunts were not. Diverting shunts significantly improved splenomegaly. In conclusion, we have demonstrated that patients without cirrhosis with PVT have significant liver atrophy and splenomegaly. Significant liver regeneration was achieved after portal flow-preserving shunts. Liver Transplantation 24 881-887 2018 AASLD.

Marked accumulation of oligodendroglia-like cells in temporal lobe epilepsy with amygdala enlargement and hippocampal sclerosis.

Although an increasing number of cases of temporal lobe epilepsy (TLE) with ipsilateral amygdala enlargement (AE) have been reported, there are few pathological reports, and no clear consensus has been established. Oligodendroglia or oligodendroglia-like cells (OLCs) have recently attracted attention in epilepsy studies. Here, we report the clinical and pathological findings of a 40-year-old male TLE patient with AE and hippocampal sclerosis, in whom histopathological study demonstrated remarkable clustering of OLCs around the uncus. The patient began to have refractory seizures at the age of 14, and preoperative MRI revealed left amygdala enlargement and left hippocampal atrophy. Other examinations were consistent with left mesial temporal epileptogenicity. He underwent surgical resection and achieved seizure freedom. Histopathological study of the amygdala showed swollen neurons with relatively large bodies and thick neurites, accompanied by vacuolar degeneration in the background. Additionally, there were marked clusters of OLCs with round nuclei and densely stained chromatin around the uncus. The OLCs were Olig2-positive. In the hippocampus, severe cell loss in CA1 and granule cell dispersion in the dentate gyrus were found. These findings may provide some insights for further pathological investigations of TLE with non-neoplastic AE.

Device-based treatment for vaginal wellness.

Genitourinary syndrome of menopause (GSM), encompassing the disorders of atrophic vaginitis, urinary incontinence, and pelvic prolapse, affects the majority of postmenopausal women, as well as patients who are undergoing breast cancer treatement, post-ovarectomy, post-radiation, and breast-feeding. There is a need for better treatment options for these common conditions that adversely affect physical function and quality of life and that are often underserved by existing options. Lasers have been used to treat genitourinary tissue for over 40 years, and over the past decade, several lasers and radiofrequency devices have been developed and clinically tested for the treatment of GSM, with an accumulating body of evidence demonstrating their safety and efficacy. Fractional lasers, including carbon dioxide, erbium: YAG and hybrid technologies, as well as monopolar radiofrequency devices, work by resurfacing and/or stimulating via heat the vaginal lining resulting in a re-epithelialization, neovascularization, and remodeling of the vaginal tissue from an atrophic postmenopausal state to a thickened, glycogen-rich and well-vascularized state similar to premenopausal vaginal lining. These changes are correlated clinically with improved function on a variety of validated vaginal health scales and urinary incontinence tests. Currently cleared for general application to genitourinary tissue, clinical trials are underway for FDA clearance or approval for specific GSM indications.

Labia Majora Augmentation Combined With Minimal Labia Minora Resection: A Safe and Global Approach to the External Female Genitalia.

BACKGROUND: All the labia minora reduction techniques fail to treat the other component of the abnormally increased labia minora to majora ratio: the labia majora atrophy. The purpose of this study is to describe a technique of female genitalia beautification, which combines labia majora augmentation and conservative labia minora reduction. METHODS: The hypertrophied labia minora were first treated by a conservative inferior wedge excision with a superior flap. The conservative excision was done to obtain labia minora that would still protrude beyond the labia majora because it will be masked by the augmentation of the labia majora. Labia majora augmentation was done by autologous fat transplantation. The newly augmented labia majora completely masked the conservatively reduced labia minora. RESULTS: Twenty-one patients underwent surgery for labia majora augmentation and labia minora reduction. One patient (4.7%) had a small separation of the labial edge postoperatively that resolved with no additional interventions. There was no flap necrosis or infections. No patient reported pain or sexual dysfunction. Seventeen patients (81%) were satisfied or very satisfied with their results. CONCLUSIONS: Labia majora augmentation combined with a conservative labia minora reduction is an appealing procedure because it enhances the global aspect of the female genitalia while reducing the labioplasty complications.

Soft Tissue Atrophy Related to Corticosteroid Injection: Review of the Literature and Implications for Hand Surgeons.

Corticosteroid injections (CIs) are frequently used by hand surgeons to treat a wide range of pathology including de Quervain tenosynovitis and lateral epicondylitis. Although generally viewed as a benign modality, and a way to potentially avoid or postpone surgical intervention, common complications from CI should be considered and discussed with patients before the procedure. One such complication is local soft tissue atrophy and hypopigmentation after injection. We discuss the incidence of soft tissue-related adverse effects from CI, the pathophysiology and influence of different steroid preparations on soft tissues, and potential treatment options once atrophy has occurred.

Use of Recombinant Human Bone Morphogenetic Protein-2 Associated With Lyophilized Bovine Bone in Reconstruction of Atrophic Maxilla.

Cases of severely atrophic edentulous maxilla require reconstruction techniques employing bone grafts to promote adequate bone dimension for the successful placement of dental implants for prosthetic rehabilitation that reestablishes the patient's function and aesthetics. This study aims to present a severely atrophic edentulous maxilla reconstruction with the off-label use of recombinant human bone morphogenetic protein type 2 (rhBMP-2) associated with lyophilized particulate bovine bone xenograft for the prosthetic rehabilitation with osseointegrable dental implants. The paper describes a case of severely atrophic edentulous maxilla in a 42-year-old woman referred to the dental school with complaint of failure in adaptating to the dentures. The patient reported 27 years of maxilla edentulism and consecutive treatment failures, so the proposed therapy was the reconstruction of the maxilla with an association of rhBMP-2 and lyophilized bovine bone xenograft for increasing bone volume and further prosthetic rehabilitation with osseointegrated dental implants. The present report illustrates a case of atrophic edentulous maxilla in which the off-label use of rhBMP-2 was successful and the patient's prosthetic rehabilitation could be concluded. The 8 dental implants received prosthetic functional load during 1 year of follow-up with no complications. Based on the case presented, the association between rhBMP-2 and a bovine bone xenograft could be considered a viable option for the reconstruction of atrophic edentulous maxilla. After a year of functional prosthetic load follow-up, the patient is asymptomatic and satisfactorily adaptated to the prosthesis, which restored her functional and aesthetic demands.

Atrophic Maxilla Reconstruction With Autogenous Iliac Graft and Guided Dental Implants.

Oral rehabilitation with osseointegrated implants is frequently the best alternative for replacement of lost teeth. Several techniques and materials allow achievement of excellent function and esthetics. In the case of maxillary or mandibular atrophy, extensive grafting may be necessary before implants can be properly placed. This is a case of maxillary reconstruction with autogenous iliac crest bone grafts, followed by placement of guided implants. After integration of the grafts, planning and insertion of implants allowed installation of an implant-supported prosthesis, recovering the morphology, function, and esthetics.

Outcome of Conventional Adipose Tissue Grafting for Contour Deformities of Face and Role of Ex Vivo Expanded Adipose Tissue-Derived Stem Cells in Treatment of Such Deformities.

OBJECTIVES: To evaluate the outcomes of conventional fat grafting for facial contour deformities and to describe clinical outcome of a patient with contour deformity of face treated with ex vivo expanded adipose tissue-derived mesenchymal stem cells (ASCs) enriched fat graft. PLACE AND DURATION OF STUDY: The Department of Plastic Surgery and Tissue Engineering and Regenerative Medicine Laboratory, King Edward Medical University/Mayo Hospital, Lahore, from September 2015 to September 2017. METHODS: Patients with contour deformities of face requiring soft tissue augmentation were included. Fat was harvested, processed, and injected following a standard protocol. Both subjective and objective assessments were performed and complications were also noted. RESULTS: Twenty-five patients underwent 51 fat-grafting sessions over a period of 24 months. Eighteen (72%) patients underwent multiple fat-grafting sessions. Mean (standard deviation) soft tissue thickness after 72 hours and 6 months of first fat graft session was 18.62 (7.2) and 12.88 (6.21) mm, respectively, which corresponds to 30.77 (13)% reduction of transplanted fat. Physician and patient assessment scores were 3.42 (0.92) and 4 (1.04), respectively. Few minor complications were observed. In the patient undergoing ex vivo expanded ASCs enriched fat graft, there was minimal decrease in soft tissue thickness of treated area (44 mm vs 42 mm) 6 months postoperatively and patient was highly satisfied with the outcome after the single session. CONCLUSION: Conventional fat grafting is safe for correction of facial contour deformities. However, procedure needs to be repeated multiple times to produce satisfactory results. Beneficial effects of ex vivo expanded ASCs enriched fat grafting have a potential to alter the current treatment paradigm of fat grafting for soft tissue reconstruction.

Fractional CO2 laser therapy: a new challenge for vulvovaginal atrophy in postmenopausal women.

OBJECTIVE: To evaluate the effects of CO2 laser in the treatment of vulvovaginal atrophy (VVA) in postmenopausal women. METHODS: VVA was assessed in 87 postmenopausal women (mean age 58.6 ± 6.9 years) before and after the treatment. The protocol consisted of three monthly treatments and included the treatment of vulva. Subjective measures included VAS (Visual Analog Scale) both for vaginal dryness and dyspareunia; DIVA (Day-by-day Impact of Vaginal Aging); a questionnaire on treatment satisfaction and one about the degree of pain during the procedure. Objective measures included VHI (Vaginal Health Index) and VVHI (Vulvo-Vaginal Health Index). Time points of the study were at the screening visit (T0), at baseline (T1), at week 4 (T2), at week 8 (T3), after 3 months since the last laser application (T4), after 6 months (T5), after 9 months (T6), after 12 months (T7) and after 15 months (T8). RESULTS: Treatment induced significant improvement in the VAS score. After treatment, VHI and VVHI indicated no VVA and this improvement was long lasting. Multivariate analysis showed that the time of follow-up was correlated with better VHI and VVHI (p < 0.001). DIVA improved over time (p < 0.001). CONCLUSIONS: This study shows that CO2 laser treatment induces a significant and long-lasting improvement of symptoms.

Blunt Blade Subcision: An Evolution in the Treatment of Atrophic Acne Scars.

BACKGROUND: Subcision is the mainstay of atrophic acne scar treatment but the efficacy and safety of the procedure is controversial. OBJECTIVE: To improve the efficacy of the subcision procedure, a blunt subcision blade was designed and evaluated. METHODS: Eighteen patients with bilateral atrophic acne scars considered eligible for subcision were enrolled. Before subcision, a tumescent solution was injected subdermally to anesthetize the treatment area and aid the dissection of the dermal-subcutaneous tissue. Patients underwent treatment using the blunt subcision blade, a long metal blade with gradually narrowing edges, and a rounded blunt tip. Early postoperative complications, overall aesthetic improvement and persistent discoloration, or lumpiness were assessed 7 days after subcision and at a 6-month follow-up visit. RESULTS: Moderate to marked improvement of atrophic scars was observed in 15 cases (83.3%). Mild to moderate tenderness, periorbital ecchymoses, and swelling were reported by some patients, but resolved completely within 1 week after the procedure. No cases of persistent discoloration or lumpiness were observed at the final visit. CONCLUSION: The blunt blade subcision procedure is suggested as an effective method for the treatment of atrophic acne scars.
