Corrección de arrugas perioculares con plasma rico en plaquetas / Correction of periocular wrinkles with platelet-rich plasma

Las arrugas son surcos o pliegues en la piel, que aparecen principalmente por efecto del envejecimiento. Este artículo describe el caso de un paciente masculino de 47 años de edad, piel blanca, que acudió a consulta de cirugía plástica ocular por inconformidad con el aspecto envejecido de su rostro a causa de las arrugas perioculares. Se le aplicó plasma rico en plaquetas intradérmico en el trayecto de las arrugas a razón de 3 dosis con intervalo promedio de 30 días entre cada una. Se logró la corrección total de las arrugas, con buenos resultados estéticos. No se encontró reacción adversa. Se reafirma el criterio planteado por estudios de que el plasma rico en plaquetas es una opción terapéutica de primera línea para rejuvenecer la región periocular(AU)

Wrinkles are a creases or folds which appear in the skin mainly as a result of aging. A case is described of a male 47-year-old patient of white skin color who attended ocular plastic surgery consultation for dissatisfaction with the periocular wrinkles on his face, which gave it an aged appearance. Intradermal platelet-rich plasma was applied along the course of the wrinkles at three doses with an average separation of 30 days between them. Total wrinkle correction was achieved, with good esthetic results. There was not any adverse reaction. The case confirms the criterion contained in previous studies that platelet-rich plasma is a first-line therapeutic option to rejuvenate the periocular region(AU)

Case for diagnosis. Noninfectious suppurative panniculitis induced by mesotherapy with deoxycholate

Abstract A 28-year-old white female patient presented with multiple erythematous-to-violaceous, painful, suppurative nodules on the buttocks and thighs that appeared after two weeks of mesotherapy with deoxycholate, caffeine, sunflower liposomes, and sinetrol for localized fat. She was treated for atypical mycobacteriosis, but with no satisfactory response after antibiotic therapy. Bacterial, mycobacterial, and fungal culture were all negative. Histopathologic examination of the biopsy showed noninfectious suppurative panniculitis. It resolved after treatment with methotrexate, prednisone, and hydroxychloroquine. This report highlights the rarity of this complication, the importance of its early recognition, and differentiation with atypical fast growing mycobacterioses.

Histologic Evidence of New Collagen Formulation Using Platelet Rich Plasma in Skin Rejuvenation: A Prospective Controlled Clinical Study

BACKGROUND: Platelet-rich plasma (PRP) is an autologous concentration of human platelets contained in a small volume of plasma and has recently been shown to accelerate rejuvenate aging skin by various growth factors and cell adhesion molecules. OBJECTIVE: This study was conducted to evaluate the efficacy and safety of intradermal injection of PRP in the human facial rejuvenation. METHODS: This study was a prospective, single-center, single-dose, open-label, non-randomized controlled clinical study. PRP injected to the upper site of this right infra-auricular area and all face. Saline was injected to the left infra-auricular area. Histopathological examinations were performed before PRP treatment, 28 days after the PRP, and saline (control) treatments. RESULTS: Twenty women ranging in age from 40 to 49 years (mean age, 43.65±2.43 years) were enrolled in the study. The mean optical densities (MODs) of collagen in the pre-treatment, control, and PRP-treated area were measured. They were 539±93.2, 787±134.15, 1,019±178, respectively. In the MOD of PRP, 89.05 percent improvement was found when MOD of PRP was compared with MOD of pre-treatment. The mean MOD of collagen fibers was clearly highest on the PRP side (p<0.001). The PRP-to-saline improvement ratio (89.05% to 46.01%) was 1.93:1. No serious side effects were detected. CONCLUSION: PRP increases dermal collagen levels not only by growth factors, but also by skin needling (the mesotherapy technique 'point by point'). PRP application could be considered as an effective (even a single application) and safety procedure for facial skin rejuvenation.

Intradermal Therapy (Mesotherapy) for the Treatment of Acute Pain in Carpal Tunnel Syndrome: A Preliminary Study

BACKGROUND: The carpal tunnel syndrome (CTS) is the most common cause of severe hand pain. In this study we treated acute pain in CTS patients by means of local intradermal injections of anti-inflammatory drugs (mesotherapy). METHODS: In twenty-five patients (forty-five hands), CTS diagnosis was confirmed by clinical and neurophysiological examination prior to mesotherapy. A mixture containing lidocaine 10 mg, ketoprophen lysine-acetylsalycilate 80 mg, xantinol nicotinate 100 mg, cyanocobalamine 1,000 mcg plus injectable water was used. Sites of injection were three parallel lines above the transverse carpal ligament and two v-shaped lines, one at the base of the thenar eminence, and the other at the base of the hypothenar eminence. RESULTS: The day after the treatment, all but four patients reported a significant reduction in pain and paresthesias. After 12 months, 17 patients had a complete pain relief, eight patients reported recurrence of pain and sensory symptoms and four out of them underwent surgical treatment. CONCLUSIONS: With the obvious limits of a small-size open-label study, our results suggest that mesotherapy can temporary relieve pain and paresthesias in most CTS patients and in some cases its effect seems to be long-lasting. Further controlled studies are needed to confirm our preliminary findings and to compare mesotherapy to conventional approaches for the treatment of CTS.

Safety Evaluation of Stamp Type Digital Microneedle Devices in Hairless Mice

BACKGROUND: Microneedles provide a minimally invasive means to transport molecules into the skin. A number of specific strategies have been employed to use microneedles for transdermal delivery. OBJECTIVE: The purpose of this study was to investigate the safety of two new digital microneedle devices (Digital Hand(R) and Digital Pro(R); Bomtech Electronics Co., Ltd., Seoul, Korea) for the perforation of skin in skin-hairless-1 mice. This device replaces conventional needles and is designed specifically for intradermal delivery. METHODS: We used two newly developed digital microneedle devices to perforate the skin of skin-hairless-1 mice. We conducted a comparative study of the two digital microneedle devices and DTS(R) (Disk type-microneedle Therapy System; DTS lab., Seoul, Korea). To evaluate skin stability, we performed visual and dermatoscopic inspections, measurements of transepidermal water loss, and biopsies. RESULTS: The two novel digital microneedle devices did not induce significant abnormalities of the skin on visual or dermatoscopic inspection, regardless of needle size (0.25~2.0 mm). No significant histopathological changes, such as inflammatory cell infiltration, desquamation of the stratum corneum, or disruption of the basal layer, were observed. The digital microneedle devices and microneedle therapy system produced similar results on measures of skin stability. CONCLUSION: These two novel digital microneedle devices are safe transdermal drug delivery systems.

Only smaller adverse effects were observed. Conclusion: This study suggests that mesotherapy can be efficient in the treatment of rotator cuff tendinopathy, for the improvement of pain, ROM, or global functioning of the upper limb. The clinical impact of this study is that mesotherapy can be associated with the standard physical therapy treatment to improve ROM and pain in rotator cuff tendinopathy.

Tratamento dos sulcos palpebromalar e nasojugal com ácido hialurônico / Treatment of tear trough deformity with hyaluronic acid gel filler

OBJETIVO: Verificar a eficácia do preenchimento dos sulcos nasojugal e palpebromalar deprimidos através da injeção de ácido hialurônico e analisar as complicações observadas. MÉTODOS: Foi realizado um estudo piloto, prospectivo, aprovado pelo Comitê de Ética em Pesquisa da Universidade Federal de São Paulo, com pacientes recrutados no Serviço de Plástica Ocular do Departamento de Oftalmologia da UNIFESP/EPM. Foram selecionados pacientes de ambos os sexos, com idade entre 25 e 60 anos, que apresentavam os sulcos nasojugal e/ou palpebromalar deprimidos, que não haviam sido submetidos à cirurgia na pálpebra inferior nem apresentavam histórico de trauma nesse local. O ácido hialurônico foi aplicado via transcutânea e depositado na região supraperiosteal em pequenos volumes. Todo paciente foi tratado pelo mesmo cirurgião (GAPV), tendo sido examinado no pós-operatório em intervalos regulares e fotografado no pré-operatório, no pós-operatório imediato, na 4ª semana, no 6º e no 12º mês após o procedimento. Ao final deste período todas as fotos foram analisadas por profissional não ligado a esta pesquisa, visando verificar a eficiência da técnica em atingir seus objetivos. RESULTADOS: Entre junho e agosto de 2008, 10 pacientes foram incluídos neste estudo piloto. Oito pacientes foram tratadas uma única vez, enquanto duas precisaram de retoque na 4ª semana após a aplicação inicial. O volume injetado foi em média de 0,61 ml (DP=0,25) no lado direito e de 0,65 ml (DP=0,26) no lado esquerdo. As complicações observadas foram equimose em 6 casos, edema local maior que 48 horas em um paciente e lesão cutânea semelhante à acne em um participante. CONCLUSÕES: O estudo piloto demonstrou que o tratamento dos sulcos nasojugal e pálpebro-malar com uso de ácido hialurônico se mostrou eficaz e previsível, com alto nível de satisfação dos pacientes e com resultado duradouro.

BACKGROUND: Volume loss and muscular hyperactivity are two major components of the aging process that contribute to the formation of the folds and wrinkles. Tear trough deformity is one of the most difficult depressions to correct surgically. PURPOSE: The aim of this study was to evaluate the results of ten patients submitted to periorbital filling with hyaluronic acid gel filler. METHODS: Between June and August, 2008, 10 patients have had their tears troughs treated with hyaluronic acid gel filler. The filler was introduced by a serial puncture technique and approximately 0.1 ml was injected at each pass. The filler was placed in the pre-periosteal tissue. Patients photographs before and after the procedure were reviewed to assess the outcomes. RESULTS: The mean volume per side needed to achieve correction was on the right side 0.61 ml (SD=0.25) and on the left side 0.65 ml (SD=0.26). The most common complications were bruising, erythema, local swelling, and pain at the injection site. The effect of treatment lasted up to 12 months. CONCLUSIONS: This pilot study showed that the treatment of tear trough deformity with hyaluronic acid gel filler was feasible, predictable and effective. All patients were very satisfied with their results.

Mesoterapia: uma revisão bibliográfica / Mesotherapy: a bibliographical review

A intradermoterapia é um procedimento médico introduzido por Pistor, em 1958, e consiste na aplicação, diretamente na região a ser tratada, de injeções intradérmicas de substâncias farmacológicas muito diluídas. Esse método é capaz de estimular o tecido que recebe os medicamentos tanto pela ação da punctura quanto pela ação dos fármacos, e apregoa-se que sua vantagem é evitar o uso de medicação sistêmica. Há relatos da utilização da intradermoterapia para tratamento de doenças dolorosas, dermatoses e condições consideradas inestéticas. Atualmente, clínicas médicas oferecem esse tratamento, utilizando, porém, o nome mais popular para essa prática, mesoterapia. Há escassa informação científica sobre o tema publicada em periódicos indexados no MedLine e poucos estudos com metodologia mais rigorosa sobre a eficácia e o mecanismo de ação da via intradérmica. A maioria das publicações indexadas sobre esse tema versa sobre as complicações dessa técnica. As dermatoses inestéticas têm se tornado queixas frequentes nos consultórios dermatológicos, sendo necessário um embasamento científico para lidar com tais pacientes, os quais, muitas vezes, estão em busca das novidades mostradas através da mídia. Assim, há necessidade de estudos cientificamente bem conduzidos sobre essa técnica. Estes estudos deverão oferecer aos médicos elementos para esclarecer os pacientes sobre quais benefícios esperar e quais os riscos de tal abordagem. Desse modo, realizou-se uma revisão bibliográfica sobre o assunto e constatou-se a necessidade de novos estudos com metodologia adequada para a confirmação dos benefícios da intradermoterapia como ferramenta útil no tratamento dermatológico.

Intradermotherapy is a medical procedure introduced by Pistor in 1958 that consists in the application of intradermal injections of diluted pharmacological substances that are given directly into the region to be treated. There are reports of the use of intradermotherapy to treat painful diseases, skin diseases and unaesthetic conditions. Medical clinics have been recently offering the treatment of intradermotherapy, using the more popular name for this practice - mesotherapy. There is only scant scientific information about this subject published in periodicals indexed on MedLine. Only a few states rigorously pursue this method. Most indexed publications about this subject deal with the complications of this technique. Unaesthetic dermatoses have been a common complaint in dermatologic clinics, and it has become necessary to have scientific evidence to give to patients. Therefore, well-researched scientific studies about this technique are necessary to offer data to medical professionals that will clearly explain to patients both the benefits and the risks of these procedures. A bibliographical review was conducted and we verified the need for new studies with adequate methods to confirm the benefits of intradermotherapy as used in dermatologic treatment.

Can Platelet-rich Plasma Be Used for Skin Rejuvenation? Evaluation of Effects of Platelet-rich Plasma on Human Dermal Fibroblast

BACKGROUND: Autologous platelet-rich plasma has attracted attention in various medical fields recently, including orthopedic, plastic, and dental surgeries and dermatology for its wound healing ability. Further, it has been used clinically in mesotherapy for skin rejuvenation. OBJECTIVE: In this study, the effects of activated platelet-rich plasma (aPRP) and activated platelet-poor plasma (aPPP) have been investigated on the remodelling of the extracellular matrix, a process that requires activation of dermal fibroblasts, which is essential for rejuvenation of aged skin. METHODS: Platelet-rich plasma (PRP) and platelet-poor plasma (PPP) were prepared using a double-spin method and then activated with thrombin and calcium chloride. The proliferative effects of aPRP and aPPP were measured by [3H]thymidine incorporation assay, and their effects on matrix protein synthesis were assessed by quantifying levels of procollagen type I carboxy-terminal peptide (PIP) by enzyme-linked immunosorbent assay (ELISA). The production of collagen and matrix metalloproteinases (MMP) was studied by Western blotting and reverse transcriptase-polymerase chain reaction. RESULTS: Platelet numbers in PRP increased to 9.4-fold over baseline values. aPRP and aPPP both stimulated cell proliferation, with peak proliferation occurring in cells grown in 5% aPRP. Levels of PIP were highest in cells grown in the presence of 5% aPRP. Additionally, aPRP and aPPP increased the expression of type I collagen, MMP-1 protein, and mRNA in human dermal fibroblasts. CONCLUSION: aPRP and aPPP promote tissue remodelling in aged skin and may be used as adjuvant treatment to lasers for skin rejuvenation in cosmetic dermatology.

Infected Skin Necrosis after Mesotherapy

Recently, mesotherapy is frequently used for body contouring. But, there is a many controversy on the effect of mesotherapy for fat reduction, as well as it's complication tends to look over. So, we let you know the complicated case of the mesotherapy which we experienced. A 28-year-old woman after mesotherapy on her right lateral thigh was admitted to the hospital because of cellulitis and skin necrosis. The patient had a local injection on the both her lateral thigh for body contouring at local hospital. 2 days before hospitalization, we could see infection on her right lateral thigh. The infection finding was swelling, reddish to purple color change and bullae formation. As time goes by, skin necrosis and eschar formation took a place. The size of eschar was estimated about 12 x 10 cm. MRI was accomplished, and the cellulitis on the right hip ant thigh was found on the MRI. The eschar was surgically removed and wound bed was exposed to subcutaneous fatty layer. And then, split thickness skin graft taken from left lateral thigh was done successfully. The grafted skin was well taken without complication, as well as donor site was well healed. The mesotherapy for body contouring is tried by various method, but, the definite mechanism is not established and safe way of drug combination is not clear. For more safer procedure, more study about the way of drug combination and mechanism is needed.

A Case of Localized Urticaria Induced by Mesotherapy / 대한피부과학회지

Mesotherapy is a widely used technique of intradermal or subcutaneous microinjection of a drug or cocktail of drugs, at sites of the body with medical or aesthetic problems. Rare cutaneous side effects have been previously reported, including allergic reactions to the administered drugs or skin infections. We herein report a case of an immediate adverse reaction following mesotherapy. A 40-year-old woman was referred to our department with pruritic erythematous urticarial plaques at the sites of application of mesotherapy. She had been treated for abdominal liposis with one session of multiple subcutaneous injections of a drug mixture including aminophylline at a local clinic. After clinical recovery, a skin test using the same drugs was performed. A positive intradermal test was found with aminophylline and ethylenediamine that is an ingredient of aminophylline. These results support that the ethylenediamine component of aminophylline is identified as the etiologic agent.

Tratamiento combinado de cicatrices de larga evolución: Resultado estético y reparador en una adolescente / Combined treatment of old scars: Aesthetic and reparative results in an adolescent

Las cicatrices extensas son lesiones que condicionan la vida de los pacientes que las padecen, produciendo retracción social o como en este caso condicionando la vestimenta de una joven adolescente de 15 años. Se realiza el tratamiento de cicatrices postquemadura que padece desde los 2 meses de edad, combinando diversos métodos como peeling, mesoterapia, dermoabrasión y ultrasonido, obteniendo como resultado la mejoría clínica, estética y psicológica, brindándole una calidad de vida superior.

Extensive scars modify the patient's life. Significant scarring causes functional and cosmetic deformities, discomfort and psychological stress. We report a teenager, who suffered from burning when she was two months old. She has been under scar treatment combining several methods such as peeling, mesotherapy, manual dermoabrasion and ultrasound. Up to now, we improved the patient's life quality, obtaining a clinical improvement, such as aesthetic and psychological one.

The Effect of Medications Used in Mesotherapy on Hair Organ Culture and Culture of Dermal Papilla Cells / 대한피부과학회지

BACKGROUND: Hair loss including androgenetic alopecia and chronic telogen effluvium is recognized increasingly as a physically and psychologically harmful medical condition. Mesotherapy is considered as a new therapeutic modality for hair loss. OBJECTIVE: We studied to determine the effect of medications used in mesotherapy on hair organ culture and culture of dermal papilla cells. METHODS: First, occipital hair follicles were collected from patients with androgentic alopecia and separated into single hair follicles. The single hair follicles were cultured in William E media mixed with mesotherapy medications such as lidocaine, placental extract, Pondil(R), CRP-1000(R), and mixture of all these medications at different concentrations (1, 10, 50 microliter). On the 8th day, the cultured single hairs were stained with H&E and the length of those was measured under a microscope to compare with control group. Immunofluorescent study was performed to check expression of Ki-67, Bcl-2 and Bax on the hairs. Second, dermal papilla cells were isolated from occipital anagen hairs of patients with androgenetic alopecia and cultured in Dulbeco's modified Eagle's medium (DMEM). The mesotherapy medicines were added to the medium with one and two thousand dermal papilla cells, respectively. At the 3rd day, survival of the cells was evaluated with ELISA method comparing with control group. RESULTS: There were no statistical differences of the length of the hairs and the survival of the dermal papilla cells between experimental and control groups. With Bcl-2, we couldn't see any differences between experimental and control groups. With Ki-67, experimental groups showed less expression than control group. On the contrary, experimental groups showed more expression than control group in case of Bax. CONCLUSION: We can conclude from the results that the four medications used in mesotherapy are not effective for growth of cultured hair follicles and survival of cultured dermal papilla cells. However, more study would be needed for the establishment of objective and scientific evidences supporting mesotherapy and we should be in search for new medications for mesotherapy.

Clinical Tips and Recent Advances in Cosmetic Uses of Botulinum Toxin Including Mesobotox

In this article, general clinical tips when handling the botox are reviewed including its reconstitution, storage, comparison of commercial products, safety, immunogenicity when repeatedly injected, etc. In addition, recent advances in the clinical use of botox in the cosmetic field including mesobotox, an intradermal injection of botox are comprehensively discussed. Mesobotox is a hybrid word from mesotherapy and botox, and is a new technique combined with conventional intramuscular injection and intradermal injection of botox. When injected intradermally, botox seems to bring about dermal edema due to transient and mild lymphatic insufficiency from underlying muscular paralysis. Botox can also relax smooth muscle of dermal vasculature. Dermal edema can make the skin look tight in turn. Therefore, fine static wrinkles are improved and dilated pores are also improved with mesobotox in addition to the original effect of botox on expression lines. Another important point of mesobotox is the improvement of aged appearance including elevation of the lateral part of eyebrow and contouring the masseteric hypertrophy. The major advantage of mesobotox is that it gives a natural-look because it does not paralyze the deeper part of facial expression muscles even if we inject botox on the mid to lower part of the face.

A Case of Panniculitis Following Mesotherapy / 대한피부과학회지

Mesotherapy was first introduced in France by Pistor in 1952. This is a widely used technique of intradermal or subcutaneous microinjections of a highly diluted drug, or cocktail of drugs. The use of mesotherapy is commonplace in medicine, especially in painful disorders of the locomotory apparatus. The technique has also been employed in cutaneous affections and esthetical conditions such as keloids and hypertrophic scars, acne, psoriasis, vitiligo, wrinkles, alopecia areata and hair loss, cellulitis, lipodystrophy, obesity, telangiectasias, lymphedemas, peripheral vascular diseases, and leg ulcers. A 24-year-old woman presented with painful eczematous subcutaneous nodules located at the points where mesotherapy had been applied. Histologically, it showed panniculitis with acute inflammation, aggregation of neutrophils, and fat necrosis. We report an unusual case of panniculitis after mesotherapy.
