RESUMEN

BACKGROUND: Periorbital hyperpigmentation (POH) is a common cosmetic concern. Numerous techniques of treatment have been assessed with variable results. AIM: The purpose of this research is to assess the efficacy of non-ablative radiofrequency, Sublative fractional Radiofrequency (SFR) on POH treatment. METHODS: In this research study, nine patients with POH and the age range of 25-57 years, were enrolled. The patients were treated by non-ablative radiofrequency SRF. The outcomes were assessed by biometric assessment. The skin lightness and melanin content of the periorbital skin were assessed by colorimeter and Mexameter. Skin elasticity was assessed by Cutometer. The skin ultrasound imaging system was used to evaluate the diameter and density of the epidermis and dermis. Visioface was used to evaluate the skin color and wrinkles. Also, patient's satisfaction and physician's assessment were assessed. RESULTS: The results showed that the lightness and elasticity of the periorbital skin were significantly increased after treatment. Also, the melanin content of the skin was decreased. The denser skin layers were seen in both dermis and epidermis. The Visioface results displayed the reduction in the percent change of the skin color and wrinkle (p < 0.05). Similarly, the physician and patients' assessment confirmed the outcomes. No serious adverse effect was reported. CONCLUSION: In conclusion, the SFR technique is an effective and satisfactory therapeutic choice for treatment of POH.

RESUMEN

BACKGROUND: Burns are caused by a variety of mechanisms, including flames, hot liquids, metallurgy, chemicals, electric current, and ionizing and non-ionizing radiation. The most significant burn wound management involves complete repair and regeneration as soon as possible while minimizing infection, contraction, and scarring in the damaged tissue area. Some factors such as delivery of nutrients, growth factors, and oxygen are essential to promote and stimulate the wound healing progress in the burns area. When these factors are not provided, the burn wound undergoes a physiological crisis. The use of growth factors is a promising approach to overcoming this limitation. Umbilical cord blood platelet concentrates are a rich natural source of growth factors. METHODS: This clinical trial used growth factors released from the lysis of umbilical cord blood platelet concentrates that have a key role in promoting re-epithelization and regeneration of damaged tissues by forming a fibrin network. This study evaluated the effectiveness of allogeneic cord blood platelet gel topical dressing in a group of patients diagnosed with superficial and deep partial thickness (second-degree) burn wounds. Clinical outcomes were compared between the intervention group and a control group of patients with superficial second-degree burn wounds who received the standard routine treatment including paraffin gauze wound dressing and silver sulfadiazine ointment. RESULTS: The study's results showed that the increased rate of recovery and tissue granulation completely promoted to wound healing and burn wound closure, decreased the recovery time, and reduced inflammation and scars caused by burn injuries. However, the use of cord blood platelet gel topical dressing is not currently a routine treatment method in patients suffering from burn wounds. However, the study's results showed that allogenic cord blood platelet gel could be used to treat superficial and deep second-degree burns as a routine treatment. It was also shown that allogenic cord blood platelet gel topical dressing could be a candidate for autograft or after autograft skin transplantation surgery (in donor and recipient sites) instead of skin surgery in some patients. CONCLUSION: Allogeneic topical wound dressing provides an effective treatment that offers a faster rate of epithelialization and healing of wounds and also decreases patients' scar and inflammation level as well as the length of recovery time. This, finally, leads to better burn wound management and the improved quality of burn wound treatment.

RESUMEN

Numerous individuals suffer from the lower eye bag. Lower eye bag treatment is a challenge that might require new methods. Depending on the cause, there are different treatment approaches to reduce puffiness under the eyes. In this pilot study, 9 patients with lower eye bags received Endolift therapy (200-300-nm fiber) and were followed up for 6 months. The patients were evaluated according to biometric characteristics. Additionally, outcomes were evaluated by three blinded dermatologists, and patients' satisfaction was assessed. The obtained biometric results showed that Endolift laser treatment could increase both the dermis and epidermis of the skin and skin elasticity in this area. Furthermore, the results indicated that Endolift therapy showed good and very good improvement in about 90% of patients. Photographic data evaluation indicated a 90% improvement in the appearance of eye bags (P < 0.05). Endolift laser seems to be a safe and effective method for lower eye bag treatment. It is a noninvasive treatment with satisfactory results with minimal downtime and side effects. Endolift therapy significantly reduces the appearance of eye bags and wrinkles and increases skin elasticity under the eyes; therefore, it is an effective method for lower eye bag treatment. The method is pain-free, bloodless, and without the need for stitches. Endolift therapy allows the patient to avoid surgery.

RESUMEN

Epidermolysis bullosa (EB) is a rare genetic disorder characterized by the formation of blisters and wounds in skin and mucous membranes; it is classified into four types and has various methods of treatment. Management of previous wounds and prevention of formation of new lesions are the most important strategies in the course of therapy to improve patient's quality of life; lack of wound management can lead to further complications such as infection. The current study investigated the therapeutic effects of allogeneic platelet gel (prepared from umbilical cord blood) in a group of children diagnosed with dystrophic epidermolysis bullosa (DEB) eligible for surgical correction of pseudosyndactyly in the hand. The post-surgical clinical outcome in this group was compared with the clinical outcomes of DEB patients receiving the standard treatment (paraffin gauze wound dressing and topical antibiotics) after corrective surgery. The current study results showed an increase in the rate of recovery and promotion of tissue granulation, complete wound healing, and a decrease in pain level and treatment period. The application of cord blood platelet gel topical dressing was not a conventional method of treatment in patients with DEB wounds and blisters. However, the current study results demonstrated that this gel dressing could effectively accelerate epithelialization and healing of the wounds and decrease patients' pain and post-surgical recovery period, which altogether leads to improvements in patients' overall quality of life.

RESUMEN

Treatment of the periorbital dark circles (PDCs) is a current challenge, with most treatment methods failing to yield promising results. The effectiveness of two common methods for periorbital dark circle treatment was compared in 28 patients with PDC. The patients were randomly divided into two groups of equal numbers: the first group received carboxy therapy, and the second group fractional 10,64 nm Q-switched Nd:YAG laser. In the carboxy therapy group, the treatment was performed six times, with 1-week intervals between sessions. In the group treated by Nd:YAG laser, the treatment was conducted in four sessions, with 1-month intervals between sessions. The results were evaluated through biometric evaluation, scoring on the visual analog scale (VAS) by both physicians and patients, and patients' satisfaction. Side effects of the treatments were also evaluated. The results showed that both carboxy therapy and Nd:YAG laser are effective in the treatment of periorbital dark circles, but carboxy therapy is significantly more effective. An increase in the skin lightness and a decrease in the melanin content of the periorbital skin was observed in the group receiving carboxy therapy, and these changes were more pronounced in this group compared to the group of Nd:YAG laser. In addition, side effects, such as erythema and post-inflammatory hyperpigmentation, were less in carboxy therapy than in Nd:YAG laser. Furthermore, the procedure was less expensive and easier to perform compared to Nd:YAG laser. Carboxy therapy is significantly more effective than Nd:YAG laser in PDC treatment.Trial registration: IRCT20080901001159N24.

RESUMEN

OF TRIAL DESIGN: Treatment of depressed acne scars requires multiple modalities. Although needle subcision is a valuable method, it exhibits mild to moderate efficacy in treatment of deep acne scars owing to the high recurrence rate and other side effects. A total of 100 patients with rolling acne scars were randomly treated using the standard technique of 18 gauge cannula and 27 gauge needle subcision in two parallel groups, and the effect of cannula subcision instead of needle subcision was evaluated in the treatment of rolling acne scars. METHODS: A total of 100 patients were randomly treated using the standard technique of 18 gauge cannula and 27 gauge needle subcision. The outcomes of these procedures were assessed by three blinded dermatologists and by patients' satisfaction. RESULTS: Subcision using the cannula showed good and very good improvement in about 83% of patients (n = 50, P < .05) based on dermatologists investigation and almost no side effects were observed in compared with needle subcision. The response rate was significantly different while using cannula subcision. CONCLUSION: Cannula subcision appears to be a safe and practical technique that can enhance the efficacy of subcision without considerable complications.

RESUMEN

BACKGROUND: Fractional radiofrequency (RF) has been used for skin rejuvenation and tightening by dermatologists and cosmetic surgeons in recent years. METHODS: Twenty female patients (mean age of 51.9 years) with Fitzpatrick III to VI skin phototypes who desired to undergo skin lift/tightening received six sessions of fractional microneedle RF treatment and were assessed at baseline and then 3 months after the last session for biometric characteristics using a Colorimeter, Visioface 1000D, Tewameter, Cutometer, Mexameter, and Sebumeter and a skin ultrasound imaging system to evaluate the transepidermal water loss (TEWL), skin pores, color, melanin content, erythema, sebaceous content, and thickness and density of the epidermis and dermis. Patient satisfaction with visual analog scale (VAS) was also measured. RESULTS: The results showed that skin pores and spots decreased significantly. TEWL also decreased significantly (by 18.44%). Meanwhile, skin density increased significantly (R7, by 44.41%). The ultrasonographic assessments showed that both the density and thickness of the dermis and epidermis were increased. The changes in the other parameters were not significant. CONCLUSION: FR increases the density and thickness of the dermis and thus also increases the collagen content and decreases skin pores and TEWL.

RESUMEN

Macular amyloidosis (MA) is a common form of primary localized cutaneous amyloidosis, characterized by the eruption of brown pigments of the skin with a rippled pattern. MA can be of cosmetic concern for patients, and its treatment is challenging. In this study, we aimed to find new effective approaches for MA treatment. A total of 39 patients with the clinical diagnosis of MA were treated with two types of laser therapy, and the effectiveness of each approach was examined. Fractional Q-switched 10.64 nm neodymium-doped yttrium aluminum garnet (Nd:YAG) laser therapy was compared with a combination of fractional Q-switched 10.64 nm Nd:YAG laser and long-pulsed fractional erbium:YAG laser therapy. Melanin biometric measurements were performed using a Mexameter, objective image-based evaluation was carried out, and the itching score and patient satisfaction were examined. Mexameter-based analysis showed that both types of laser therapy were effective in the treatment of MA, causing a significant decrease in the amount of melanin in the treated areas (P < 0.05). Also, combination of two types of laser therapy was significantly more effective than one type alone (P < 0.05). The itching score significantly decreased in patients undergoing a combination of laser therapies. Also, a positive correlation was observed between the amount of melanin and degree of itching in the treated areas. Moreover, analysis of patient satisfaction showed that more than 90% of patients had excellent satisfaction with combination laser therapy. The results confirmed the significant positive effects of both fractional Nd:YAG laser alone and in combination with fractional erbium:YAG laser therapy considering the reduction in melanin content; however, combination of two types of laser therapy was more effective than one type alone. Trial registration: IRCT20080901001159N23.

RESUMEN

This is the first study aiming to determine the therapeutic effects of the Sambucus ebulus aquatic extract as an antileishmanial herbal drug and evaluate the immune responses in Leishmania major major infected BALB/c mice. The antileishmanial activity of S ebulus aquatic extract was evaluated using MTT test as well as parasite rescue and transformation assay. Footpad swelling and parasite load of infected mice were measured by several techniques. The immune responses were evaluated by measuring the levels of IFN-γ, IL-4, nitric oxide and arginase. The results indicated that S. ebulus can significantly decrease L. major promastigotes and amastigotes viability, but it was not toxic to macrophages. The lesion size, parasite burden and the level of ARG decreased in the treated infected mice, while the IFN-γ-to-IL-4 ratio and the level of NO increased significantly. Altogether, the S. ebulus extract is an effective compound for killing Leishmania parasite without excessive toxicity to the host cells and can cure the CL by switching the host immune responses towards Th1 response. Thus, it may be a perfect therapeutic option for CL treatment.

RESUMEN

Recent progress in hair follicle regeneration and alopecia treatment necessitates revisiting the concepts and approaches. In this sense, there is a need for shedding light on the clinical and surgical therapies benefitting from nanobiomedicine. From this perspective, this review attempts to recognize requirements upon which new hair therapies are grounded; to underline shortcomings and opportunities associated with recent advanced strategies for hair regeneration; and most critically to look over hair regeneration from nanomaterials and pluripotent stem cell standpoint. It is noteworthy that nanotechnology is able to illuminate a novel path for reprogramming cells and controlled differentiation to achieve the desired performance. Undoubtedly, this strategy needs further advancement and a lot of critical questions have yet to be answered. Herein, we introduce the salient features, the hurdles that must be overcome, the hopes, and practical constraints to engineer stem cell niches for hair follicle regeneration.

RESUMEN

Leishmaniasis is a parasitic disease transmitted through the bite of an infected phlebotomine sand fly and caused by protozoan parasites of the genus Leishmania. There is no available vaccine for leishmaniasis in human, and the current chemotherapy approaches are hampered by different clinical problems. Most of available drugs are confined to a limited number of toxic chemical compounds, which some parasite strains have evolved drug resistance against. Hence, drug discovery and production of a new anti leishmanial compound is essential. One promising strategy is using the nanoparticle delivery systems with the aim of accelerating the efficacy of the available treatments. In the present study, paromomycin sulfate (PM) was formulated in solid lipid nanoparticles (SLN) and the in vivo efficacy was investigated against Leishmania tropica in BALB/c mice model. To do so, the increase in footpad thickness was measured and real-time PCR was performed to quantify the parasite load after infectious challenge. The level of nitric oxide and cytokines including interleukin-4 (IL-4) and gamma interferon (IFN -γ) were assessed. Altogether, the results show that PM loaded into SLN is significantly more effective than PM alone in inhibiting the parasite propagation and switching towards Th1 response.

RESUMEN

BACKGROUND: Noninvasive laser for body fat contouring is a quickly growing field in the cosmetic dermatology. Surgical options carry disadvantages, such as the usage of anesthetics, swelling, pain and long time for recovery, so there is a growing public request for the techniques with fewer side effects and shorter recovery periods. Several new noninvasive body contouring ways have been advanced such as, cryolipolysis radiofrequency energy, suction-massage, high-frequency focused ultrasound, and laser therapy. Noninvasive laser improves the body's appearance by the elimination of excess adipose tissue, specifically in areas in which fat perseveres in spite of diet and exercise. METHODS: In this study the efficacy of Endolift laser was evaluated for reduction of excess fat in the arms and under abdomen. Ten patients with excess fat in the arms and under abdomen were enrolled in this study. The patients were treated by Endolift laser in the arms and under abdomen areas. The outcomes were evaluated by two blinded board certified dermatologists and by patients' satisfaction. The circumference of each arm and under abdomen was measured using a flexible tape measure. RESULTS: The results showed reduction in the fat and circumference of arms and under abdomen after treatment. The treatment was considered as effective methods with high patient satisfaction. Also no severe adverse effects were reported. CONCLUSION: Endolift laser can be a good alternative to surgical body fat contouring due to its efficacy, safety, minimal recovery time, low cost. Also Endolift laser does not require general anesthetics.

RESUMEN

BACKGROUND: Acne scar treatment is a problem for both the dermatologist and the dermatologic surgeon. Many therapies have been advanced to improve acne scars over the past years. Nevertheless, they were often related to adverse side effects like hyperpigmentation. These combination therapy using subcision and autologous fibroblast injection can provide a better technique for the acne scar treatment. MATERIAL AND METHODS: In this study, we describe nine patients with the age of 25 to 48 and rolling acne scars (moderate to severe) that were treated with combination therapy using subcision (cannula, 18 gauge) and autologous fibroblast injection. Finally, before and 6 months after the final injection, the patients' biometric characteristics were evaluated by Visioface 1000D and Mexameter and a skin ultrasound imaging system. RESULTS: The results show a significant improvement in the acne scars in the patients. The Visioface results showed that the size and number of skin pores and spots were reduced after combination therapy. Also, the results of skin ultrasonography exhibited denser skin layers both in the epidermis and dermis. CONCLUSION: In summary, the combination therapy of autologous fibroblast injection and subcision can be considered as a new alternative, safe, and useful method for acne scar treatment.

RESUMEN

Drooping of the upper eyelid and eyebrow (ptosis) is common among people and cause the patients dissatisfaction. Various methods have been developed to treatment of the upper eyelid and eyebrow ptosis. However, the current methods focus on surgery to improve the disorder. But patients are worried about the risks of the procedure, and seeking for a non-invasive alternative method. Therefore, non-invasive methods with consistent efficient improvement are needed, especially for middle-aged patients. This study was conducted of 9 patients who underwent the upper eyelid and eyebrow ptosis. Endolift laser method was used to treat the patients' upper eyelid and eyebrow ptosis. The biometric assessment was used to evaluate the efficiency of the technique. Also the results were evaluated by 3 board-certified dermatologists (blind). Additionally, patients' satisfaction was evaluated at the end of the treatment. The biometric results showed that Endolift laser can increase the thickness, density, and elasticity of the skin in the eyelid area. The patient's satisfaction results showed excellent improvement in the 90% of patients. The results by the dermatologist displayed improvement in about 90% of patient. Endolift laser has been proved efficient and consistent for upper eyelid and eyebrow ptosis rejuvenation and treatment.
