ABSTRACT

OBJECTIVE@#To observe the clinical efficacy of different treatment frequency of auricular bloodletting combined with auricular point sticking for acne vulgaris.@*METHODS@#A total of 90 patients with acne vulgaris were randomized into a treatment group 1 (30 cases, 2 cases dropped off), a treatment group 2 (30 cases, 4 cases dropped off) and a treatment group 3 (30 cases, 5 cases dropped off). Combination therapy of auricular bloodletting and auricular point sticking at Fei (CO14), Shenmen (TF4), Neifenmi (CO18) and Shenshangxian (TG2p) were given once a week, twice a week and 3 times a week in the treatment group 1, the treatment group 2 and the treatment group 3 respectively, 4 weeks were as one course and totally 3 courses were required in the 3 groups. Before treatment and after 1, 2, 3 courses of treatment, the scores of global acne grading system (GAGS), skin lesion and quality of life-acne (QoL-Acne) were observed, the clinical efficacy was evaluated after 3 courses of treatment and the recurrence rate was evaluated in follow-up of 1 month after treatment in the 3 groups.@*RESULTS@#Compared before treatment, the scores of GAGS and skin lesion were decreased at each time point in the 3 groups (P<0.05), the QoL-Acne scores were increased after 1 course of treatment in the treatment group 3 and after 2, 3 courses of treatment in the 3 groups (P<0.05). There were no statistical differences in scores of GAGS, skin lesion and QoL-Acne among the 3 groups (P>0.05). There were no statistical differences in effective rate and recurrence rate among the 3 groups (P>0.05).@*CONCLUSION@#Different frequency of auricular bloodletting combined with auricular point sticking have similar efficacy in treating acne vulgaris, all can improve the skin lesion and quality of life in patients with acne vulgaris, and have a cumulative effect and good long-term curative effect.

ABSTRACT

OBJECTIVE@#To evaluate the efficacy and safety of 585 nm Q-switched laser in the treatment of acne inflammatory lesions and postinflammatory erythema.@*METHODS@#A total of 25 patients with moderate facial acne, symmetrical distribution of inflammatory lesions and postinflammatory erythema on both sides of the face, were enrolled. Among the 25 patients, 22 patients completed all the treatment and evaluation, and 3 patients were lost to follow-up. 585 nm Q-switched laser was used on a randomly selected side of the face for three times of treatment at a 2 week interval. The evaluations were made before each treatment, 2 and 4 weeks after the last treatment, therefore the evaluation time points were before the treatment, weeks 2, 4, 6, and 8, respectively, for a total of 5 times. Acne severity was assessed using the investigator' s global assessment (IGA) score, and erythema severity was assessed using the investigator' s subjective erythema score and narrow-spectrum reflectance spectrophotometer at each follow-up.@*RESULTS@#After 3 times of treatment, there was statistically significant difference between the IGA score in week 8 and before treatment on both sides(Z=2.64, P < 0.01; Z=2.67, P < 0.01). There was no significant difference in IGA score between the treatment side and the control side before treatment and in week 8 (P=0.59, P=0.26). There was statistically significant difference between the investiga-tor' s subjective erythema score in week 8 and before treatment on the treatment side(Z=4.24, P < 0.01), while no significant difference was showed on the control side(Z=1.73, P=0.08). In week 8, the investigator's subjective erythema score of the treatment side was lower than that of the control side (Z=3.61, P < 0.01). The erythema index of the treatment side was significantly decreased at 5 time points (P < 0.01), and the index decreased significantly in week 8 compared with the index before treatment (P < 0.01), while the erythema index of the control side was not significantly different at 5 time points. The treatment related adverse events included erythema and edema after treatment and pain during treatment, the severity was mild to moderate, which resolved spontaneously within 1 to 3 days. Nine patients were very satisfied with the treatment, 7 patients were satisfied, and 6 patients considered average.@*CONCLUSION@#585 nm Q-switched laser has some effect in the treatment of postinflammatory erythema, and it ensures good tolerance and safety. There was no statistically significant difference between the treatment side and the control side on the improvement of acne inflammatory lesions.

ABSTRACT

El Acné es un motivo de consulta dermatológica frecuente en la población joven de atención primaria (APS), que sin ser una patología de urgencia, se asocia a complicaciones estéticas y/o psicológicas que tienen un gran impacto en la calidad de vida del paciente. En su fisiopatología interactúan una serie de factores tales como: la queratinización anormal de la piel, y consiguiente obstrucción de la unidad pilosebácea, con posterior formación de microcomedones. El aumento del sebo, permite la colonización del P. Acnes y la consecuente cascada inflamatoria. Aunque no existe un consenso en cuanto a la clasificación, estas se pueden dividir en lesiones inflamatorias (pápulas, pústulas, nódulos o quística) o no-inflamatoria, (comedoniano). El tratamiento está orientado al tipo de lesión y su severidad. El arsenal farmacológico en APS considera el tratamiento tópico (retinoides y/o antibióticos) indicado a través de recetas magistrales y antibióticos orales para casos más avanzados. Sin embargo, a pesar de ser una patología manejable en APS, se debe tener en consideración la necesidad de derivación en casos determinados.


Acne is a frequent reason for dermatological consultation in the young population of primary care (PHC), which without being an emergency pathology, is associated with aesthetic and/or psychological complications that have a great impact on the quality of life of the patient. A series of factors interact in its physiopathology, such as: abnormal keratinization of the skin, and consequent obstruction of the pilosebaceous unit, with subsequent formation of microcomedons. The increase of sebum allows the colonization of P. Acnes and the consequent inflammatory cascade. Although there is no consensus as to the classification, these can be divided into inflammatory (papules, pustules, nodules or cystic) or non-inflammatory (comedonian) lesions. Treatment is oriented to the type of lesion and its severity. The pharmacological arsenal in APS considers topical treatment (retinoids and/or antibiotics) indicated through master prescriptions and oral antibiotics for more advanced cases. However, despite being a manageable pathology in PHC, the need for referral in certain cases must be taken into consideration.

ABSTRACT

Abstract Background: Photodynamic therapy with topical aminolevulinic acid (ALA-PDT) has been suggested to be effective in treatment of acne vulgaris. However, adverse events occur during and after treatment. Objectives: To compare the efficacy and tolerability of optical intra-tissue fiber irradiation (OFI) ALA-PDT versus traditional ALA-PDT in treatment of acne vulgaris in rabbit models. Methods: Twenty-five rabbits of clean grade were used. Twenty rabbits were randomly selected to establish acne model and the other five were used as control. Rabbits in model group (40 ears) were further divided into four groups (10 ears/group): I, OFI-ALA-PDT with the head of optical fiber inserted into the target lesion (intra-tissue); II, traditional ALA-PDT group; III, OFI group; IV, blank control group without any treatment. Uncomfortable symptoms, adverse events, and effectiveness rates were recorded on post-treatment day 14, 30, and 45. Results: On post-treatment day 14, the effectiveness rate in OFI-ALA-PDT group was obviously higher than that of the other three groups (P<0.05). However, no improved effects were observed in OFI-ALA-PDT group on day 30 and 45. During the period of treatment, the frequencies of uncomfortable symptoms in ALA-PDT group were obviously higher than those in the other three groups (P<0.05). The adverse event rate in OFI-ALA-PDT group was obviously lower than that of the ALA-PDT group (P<0.05) Study limitations: The unblindness of the study and temporary animal models of acne induced may hamper the assessment and monitoring of the results, and future studies are still needed to clarify it further. Conclusion: The OFI-ALA-PDT group (intra-tissue irradiation) showed no improved efficacy on treating rabbit ear acne but had higher safety and better tolerability.

ABSTRACT

Abstract: Acne vulgaris is an extremely common condition affecting the pilosebaceous unit of the skin and characterized by presence of comedones, papules, pustules, nodules, cysts, which might result in permanent scars. Acne vulgaris commonly involve adolescents and young age groups. Active acne vulgaris is usually associated with several complications like hyper or hypopigmentation, scar formation and skin disfigurement. Previous studies have targeted the efficiency and safety of local and systemic agents in the treatment of active acne vulgaris. Superficial chemical peeling is a skin-wounding procedure which might cause some potentially undesirable adverse events. This study was conducted to review the efficacy and safety of superficial chemical peeling in the treatment of active acne vulgaris. It is a structured review of an earlier seven articles meeting the inclusion and exclusion criteria. The clinical assessments were based on pretreatment and post-treatment comparisons and the role of superficial chemical peeling in reduction of papules, pustules and comedones in active acne vulgaris. This study showed that almost all patients tolerated well the chemical peeling procedures despite a mild discomfort, burning, irritation and erythema have been reported; also the incidence of major adverse events was very low and easily manageable. In conclusion, chemical peeling with glycolic acid is a well-tolerated and safe treatment modality in active acne vulgaris while salicylic acid peels is a more convenient for treatment of darker skin patients and it showed significant and earlier improvement than glycolic acid

ABSTRACT

Acne é a dermatose mais comum, acometendo cerca de 80% dos adolescentes e adultos jovens. É caracterizada por lesões não-inflamatórias (comedões abertos e/ou fechados) e por lesões inflamatórias (pápulas, pústulas, cistos ou nódulos) tipicamente localizados na face, pescoço, dorso, tórax e braços. A etiologia da acne vulgar resulta da associação dos seguintes fatores: hiperqueratinização e obstrução do infundíulo folicular, devido à descamação anormal do epitélio folicular; aumento da produção de sebo estimulada pelos andrógenos; colonização do folículo pelo Propionibacterium acnes, gerando inflamação. Esta guia apresenta informação que orienta a conduta para casos de acne no contexto da Atenção Primária à Saúde, incluindo: classificação da acne vulgar, Características da acne vulgar, Erupção acneiforme, Diagnóstico da acne vulgar, Tratamento - Orientações gerais, Tratamento - Medicamentos, Terapia tópica, Antibióticos sistêmicos, Terapia antiandrogênica, Acne na Gestante, Acompanhamento, Encaminhamento para serviço especializado.

ABSTRACT

Objetivo: evaluar la composición química, la sensibilidad antibacteriana y la concentración mínima inhibitoria in vitro de tres aceites esenciales de las especies vegetales Origanum vulgare L, Origanum vulgare ssp y Lippia alba Mill cultivadas en el norte del departamento de Bolívar (Colombia), obtenidos mediante hidrodestilación e hidrodestilación asistida por la radiación con microondas. Métodos: los aceites esenciales se obtuvieron por hidrodestilación e hidrodestilación asistida por radiación con microondas, a partir de las hojas; se determinó densidad relativa a 20 °C, índice de refracción, solubilidad de los aceites esenciales en etanol (70 por ciento v/v) y rotación óptica. La composición química se evaluó mediante cromatografía de gases/espectrómetro de masa (CG/EM). La actividad se realizó sobre tres bacterias implicadas en el desarrollo del acné: Propionibacterium acnes ATCC 11827, Staphylococcus aureus ATCC 25923 y Staphylococcus epidermidis ATCC 12228. Para determinar la sensibilidad antibacteriana y la concentración mínima inhibitoria, los aceites se diluyeron hasta la concentración deseada (1 000‒50 µg/mL) empleando el método de microdilución en caldo, y se empleó el lector de microplacas para la cuantificación del crecimiento bacteriano. Resultados: los rendimientos oscilaron entre 0,04 y 0,16 por ciento, dependiendo de la especie vegetal y el método de extracción utilizado. Los resultados de la prueba de sensibilidad mostraron que las bacterias fueron más sensibles al aceite esencial de orégano borde blanco (Origanum vulgare ssp) obtenido mediante ambos métodos de extracción; además, este aceite presentó el mayor contenido de monoterpenos oxigenados con reconocida actividad antibacteriana, como son el carvacrol y el timol. Conclusiones: el aceite esencial de orégano borde blanco (Origanum vulgare ssp) es considerado como promisorio para el control del componente bacteriano del acné vulgar(AU)


Objective: to assess the chemical composition, antibacterial sensitivity and the in vitro minimum inhibitory concentration of essential oils from plant species Origanum vulgare L, Origanum vulgare ssp y Lippia alba Mill cultured in the North of the Department of Bolívar (Colombia), obtained by hydrodistillation and by microwave radiation-assisted hydrodistillation. Methods: essential oils were extracted by distillation and microwave radiation-assisted hydrodistillation from the leaves; relative density at 20 °C, refractive index; solubility of the essential oils in ethanol (70 percent v/v) and optical rotation were all determined. The chemical composition was assessed using gas chromatography/ mass spectrometer The event was perfomed over three bacteria involved in the development of acne: Propionibacterium acnes ATCC 11827, Staphylococcus aureus ATCC 25923 y Staphylococcus epidermidis ATCC 12228. For the purpose of determining the antibacterial sensitivity and the minimum inhibitory concentration, oils were diluted up to reaching the desired concentration (1000-50 µg/mL) using broth microdilution method, and microplate reader for the quantification of bacterial growth. Results: Yields ranged from 0,04 to 0,16 percent, depending on the plant species and the extraction method used. The sensitivity test results showed that the bacteria were more sensitive to the essential oil oregano white border (Origanum vulgare ssp) obtained by both methods of extraction; in addition, this oil showed the greatest content of oxygenated monoterpenes, with known antibacterial activity, such as carvacrol and thymol. Conclusions: the essential oil of oregano white border (Origanum vulgare ssp) is considered as promising for the control of the bacterial component of acne vulgaris(AU)

ABSTRACT

Objetivos: evaluar la actividad antibacteriana de 19 aceites esenciales sobre tres cepas asociadas al desarrollo del acné, (Propionibacterium acnes, Staphylococcus epidermidis y Staphylococcus aureus) y seleccionar los más promisorios con base en sus respectivas concentraciones mínimas inhibitorias (CMI) y su composición química, con el propósito de diseñar formas farmacéuticas de uso tópico para tratamiento antiacné. Métodos: las bacterias se replicaron en medios de agar y caldos específicos. Se determinó el momento de máxima densidad óptica (DO 620) para emplearlo como tiempo de incubación; luego se hicieron pruebas de evaluación de sensibilidad con la exposición de las cepas a concentraciones a 1000 ppm de cada uno de los aceites en caldo. Para solubilizarlos se empleó la mezcla 95:4:1 de caldo:etanol: polisorbato-80. A los aceites que inhibieron el crecimiento en más de un 90 por ciento, se les determinó la concentración mínima inhibitoria mediante metodologías de microdilución en caldo y su composición química por cromatografía de gases acoplada a espectroscopía de masas. Resultados: de los 19 aceites, siete fueron capaces de inhibir el crecimiento en más del 90 por ciento para las tres cepas a 1000 ppm. Las concentración mínima inhibitoria determinadas oscilaron entre 300 y 900 ppm. La composición química de todos los aceites fue consistente con la reportada en la literatura. Conclusiones: los aceites de tomillo (Thymus vulgaris L.), canela (Cinnamomum verum J. Presl) y clavo (Eugenia caryophyllata T.), en ese orden, alcanzaron las más bajas de concentración mínima inhibitoria; adicionalmente, de acuerdo con la literatura, los componentes más abundantes de los aceites promisorios, tienen reconocida actividad antiinflamatoria, y por tanto, es factible el diseño de formas farmacéuticas tópicas con base en ellos, para el tratamiento del acné(AU)


Objectives: to assess the antibacterial activity of 19 essential oils against three bacterial strains associated with acnes occurrence, (Propionibacterium acnes, Staphylococcus epidermidis and Staphylococcus aureus), and to select the most promising oils on the basis of their minimum inhibitory concentrations and chemical composition, in order to design pharmaceutical dosage forms for topical acne treatment. Methods: bacteria were replicated using specific agars and broths. Time of maximum optical density (OD620) was determined to use it as the incubation time. Then susceptibility evaluation tests were made by exposing strains to 1000 ppm concentrations of each of the oils in broth. The 95:4:1 broth:ethanol:polysorbate-80 mixture was used to make oils soluble. For those oils which inhibited growth by more than 90 percent, their minimum inhibitory concentrations were determined by broth microdilution methodology and its chemical composition through gas chromatography /mass spectroscopy. Results: out of the 19 oils, seven were able to inhibit growth by more than 90 percent at 1000 ppm for the three strains. Estimated minimum growth concentrations ranged 300 to 900 ppm. The chemical composition of all oils was consistent with that reported in the literature. Conclusions: the thyme (Thymus vulgaris L.), cinnamon (Cinnamomum verum J. Presl) and clove (Eugenia caryophyllata T.) oils, reached the lowest minimum inhibitory concentrations; additionally, according to the literature, the most abundant components of the promising oils are well known by its anti-inflammatory activity and therefore it is feasible to design topical pharmaceutical forms for the treatment of acne(AU)

ABSTRACT

Durante mucho tiempo se creyó que un paciente no podía ser tratado con Homeopatía si es que, al momento de la consulta, se encontraba siguiendo un tratamiento alopático. Los doctores Morrison y Herrick establecen las pautas generales que deben seguirse al respecto y los inconvenientes que aparecen al momento de tratar de remplazar la medicina convencional por la medicina homeópata. Una parte del trabajo rescata la opinión que tienen algunos pacientes acerca de los dos sistemas clínicos terapéuticos, así como las expectativas de la familia (y de la sociedad, por extensión) en torno al método clínico configurado por Samuel Hahnemann.


For a long time it was believed that a patient could not be treated with Homeopathy if, at the time of consultation, was following an allopathic treatment. The doctorsHerrick Morrison established the general guidelines to be followed in this regard and disadvantages that appear when trying to replace the conventional medicine homeopathic medicine. Part of the work rescues the opinion they have some patients on the two treatment clinical systems as well as the expectations of the family (and society by extension) about the clinical method set by Samuel Hahnemann.

ABSTRACT

A acne é, frequentemente, uma manifestação temporária da puberdade, correlacionando-se mais com a idade puberal do que com idade cronológica. A isotretinoína é um composto retinóide (ácido 13-cis-retinoico) derivado da vitamina A, sendo indicada para o tratamento da acne cística severa e acne conglobata resistente a outras formas de tratamento. A pesquisa teve como objetivo identificar a presença de alterações lipídicas, hepáticas nos processos de coagulação e presença de anemia em pacientes que fizeram uso de isotretinoína oral para o tratamento da acne grave. Método: Essa pesquisa caracterizou-se por um estudo exploratório, aberto prospectivo da análise de exames laboratoriais de trinta pacientes que fizeram uso de isotretinoína oral. Resultados: As concentrações de colesterol e triglicerídeos apresentaram diferenças significativas (p > 0,05 e p < 0,05, respectivamente, quando analisados os resultados dos exames realizados antes do tratamento e após três meses do início do uso da isotretinoína oral. Os resultados de AST, ALT, contagem de plaquetas, hematócrito de hemoglobina estavam dentro dos valores de referências, porém foram observadas alterações estatisticamente significativas (p < 0,05 para todos os parâmetros. Conclusão: Pode-se concluir que é relevante o acompanhamento laboratorial mensal de cada paciente e que este contribui de forma direta para a manutenção de valores laboratoriais basais durante o tratamento oral com a isotretinoína.

ABSTRACT

La isotretinoína es un retinoide empleado en el tratamiento del acné. El objetivo de este estudio fue determinar colesterol, triglicéridos, transaminasa glutámico oxalacética, transaminasa glutámico pirúvica y fosfatasa alcalina, pretratamiento, trimestralmente durante el tratamiento y postratamiento en pacientes tratados con isotretinoína oral procedentes de consultas dermatológicas del Estado Carabobo. La edad Promedio de la muestra estudiada fue (19,4 ± 4,7 años), los valores de colesterol mostraron variación estadísticamente significativa para el primer trimestre (P=0,044), Los triglicéridos se incrementaron en el segundo trimestre (P=0,036) para ambos géneros, mientras que para el tercer trimestre solo el género masculino experimentó incremento. Transaminasa glutámico oxalacético en el primer trimestre se incrementó en el género femenino, sin embargo, no fue estadísticamente significativo. En los demás trimetres los valores de las enzimas hepáticas no superaron los valores de referencia. No se evidencian diferencias estadísticamente significativas entre los niveles del pretratamiento y postratamiento. Es recomendable monitorear los lípidos séricos y transaminasas durante el primer trimestre de tratamiento aunque los cambios observados fueron discretos en la mayoría de los pacientes


Isotretinoin is a retinoid used to treat acne. The aim of this sindy was to determine cholesterol, triglyceride, seric glutami oxalacetic transaminase, seric glutami pyruvic transaminase and alkaline phosphatase pretreatment, quarterly during treatment and post-treatment in patients treated with oral isotretinoin dermatological consultations from Carabobo State. The overage age of the sample was (19.4 ± 4.7 years), cholesterol values showed statistically significant variation in the first quarter (P=0.044). Triglycerides increased in the second quarter (P=0.036) for both genders, while for the third quarter only increase in male. Seric glutami oxalacetic transaminase in the first quarter increased in females, but was not statistically significant. In other quarters the liver enzyme values did not exceed reference values. No statistically significant differences are evident between the levels of pretreatment and postreatment. It is advisable to monitor serum lipids and transaminases during the first quarter of treatment although the observed changes were discrete in most patients

ABSTRACT

A acne é uma ocorrência comum, que basicamente consiste na inflamação dos folículos cutâneos, eventualmente seguida de infeção. Os objetivos do tratamento convencional são reduzir a produção das glândulas sebáceas, acelerar a renovação celular cutânea, diminuir a infecção e evitar a disseminação da infecção. Para tanto, dispõe-se de uma ampla variedade de agentes para aplicação tópica ou uso sistêmico. No entanto, a própria existência de tal variedade de abordagens aponta para o fato de que nenhuma modalidade terapêutica é completamente efetiva. A homeopatia pode constituir um valioso tratamento para a acne, na medida em que leva em consideração os sintomas e sinais mais peculiares da condição patológica reunidos em configurações sindrômicas. O presente artigo é dedicado à análise das características da acne correspondentes aos medicamentos homeopáticos Arsenicum album e Pulsatilla nigricans.


Acne is a common occurrence that basically consists in inflammation of the skin follicles eventually followed by infection. The aims of conventional treatment are to reduce the sebaceous production, increase the skin cell turnover, reduce infection and hinder the spread of infection. For that purpose, several topical and systemic agents are available. However, that very broad range of therapies points to their relative effectiveness. Homeopathy might represent a valuable treatment of acne inasmuch as it takes intrinsically consistent and coherent configurations of the most peculiar signs and symptoms of diseases into consideration. The present article describes the typical characteristics of acne corresponding to homeopathic medicines Arsenicum album and Pulsatilla nigricans.
