The Effectiveness of Herbal Medicines on Cyclic Mastalgia: A Systematic Review on Meta-analysis / A eficácia dos medicamentos fitoterápicos na mastalgia cíclica: Uma revisão sistemática em metanálise

Abstract Objective Different drugs are used to treat mastalgia, such as danazol and bromocriptine, and both are associated with side effects, due to which most of women and healthcare providers are interested in herbal medicines. Therefore we aim to study the effectiveness of phytoestrogens on the severity of cyclic mastalgia. Methods To carry out the present study, English electronic resources such as the Cochrane Library, ISI Web of Science, Scopus, and PubMed were used systematically and with no time limitation up to February 10, 2020. Results In total, 20 studies were included in the present meta-analysis. The results of the meta-analysis showed that herbal medicines versus the control group (standard mean difference [SMD] = - 0.585; 95% confidence interval [CI]: - 0.728-- 0.44; heterogeneity; p = 0.02; I2 = 42%), herbal medicines versus the B group (SMD = - 0.59; 95%CI: - 0.75-- 0.44; heterogeneity; p = 0.03; I2 = 42%), and its subgroups, such as phytoestrogen (SMD = - 0.691; 95%CI: - 0.82-- 0.55; heterogeneity; p = 0.669; I2 = 0%), Vitex-agnus-castus (SMD = - 0.642; 95%CI: - 0.84-- 0.44; p < 0.001; p = 203; I2 = 32%), flaxseed (SMD = - 0.63; 95%CI: - 0.901-- 0.367; p = 0.871; I2 = 0%), and evening primrose (SMD= - 0.485; 95%CI:- 0.84-- 0.12; p = 0.008; heterogeneity; p = 0.06; I2 = 56%] may have effective and helpful effects on improving cyclic breast mastalgia. Also, chamomile, isoflavone, cinnamon, and nigella sativa significantly reduced mastalgia symptoms. Conclusion Herbal medicines and their subgroups may have effective and helpful effects on improving cyclic breast mastalgia. The findings of our meta-analysis must be done cautiously because low methodological quality in some evaluated studies of this systematic review.

Mastitis granulomatosa idiopática: características demográficas, clínicas e imagenológicas en una serie de casos / Idiopathic granulomatous mastitis: demographic, clinical and imaging characteristics of a series of cases

Resumen: OBJETIVO: Realizar una caracterización demográfica, clínica e imagenológica de una serie de casos de mastitis granulomatosa idiopática. MATERIALES Y MÉTODOS: Estudio observacional, retrospectivo y transversal de una serie de casos de pacientes con diagnóstico de mastitis granulomatosa idiopática atendidas en el Hospital Universitario Dr. José Eleuterio González, Monterrey, NL, entre enero 2015 y diciembre 2019. Criterio de inclusión: pacientes mayores de 18 años con diagnóstico histológico de mastitis granulomatosa idiopática en ausencia de un agente etiológico específico. Criterios de exclusión: pacientes con cuadro de mastitis relacionado con una patología específica o con algún antecedente de traumatismo-laceración reciente en la mama. Variables de estudio: información demográfica (edad, escolaridad, estado civil, etc.), proceso-método diagnóstico, hallazgos por imagen y tratamientos indicados. RESULTADOS: Se incluyeron 20 pacientes con edad promedio de 32 años, 17 en edad fértil, y el resto en la posmenopausia. Las 20 pacientes tuvieron, al menos, 1 embarazo de término sumado a un periodo variable de lactancia. 19 tenían enfermedad unilateral, la mayoría en la mama izquierda (60%). El hallazgo principal al establecer el diagnóstico: en 20 una tumoración, 15 de 20 eritema y 11 mastalgia. El reporte radiológico mediante BIRADS fue de IVA en 12, IVB en 6 y 1 tanto para II y III. En todas las pacientes se comprobó el diagnóstico con estudio histopatológico. Doce recibieron tratamiento inicial con prednisona, 7 con antibióticos y AINES y un caso con escisión quirúrgica. CONCLUSIONES: La mastitis granulomatosa idiopática es una enfermedad rara de prevalencia aún desconocida, con un comportamiento benigno de tipo inflamatorio crónico, cuya patogenia permanece aún desconocida. Al ser una enfermedad con un diagnóstico por exclusión, obliga al estudio histopatológico para establecer el diagnóstico definitivo, idealmente mediante la toma de una biopsia con Tru-cut. Aunque se han planteado varias alternativas terapéuticas, en la actualidad no existe un protocolo universal que justifique un tratamiento en forma generalizada. La resección de la lesión con márgenes amplios asociada o no con corticoides orales, sigue siendo el tratamiento más indicado.

Abstract: OBJECTIVE: To perform a demographic, clinical and imaging characterization of a series of cases of idiopathic granulomatous mastitis. MATERIALS AND METHODS: Observational, retrospective and cross-sectional study of a series of cases of patients diagnosed with idiopathic granulomatous mastitis, at Hospital Universitario "Dr. José Eleuterio González in Monterrey, Mexico between January 2015 and December 2019. The study comprised all patients older than 18 years old who had histological diagnosis of idiopathic granulomatous mastitis in the absence of a specific agent. Patients with mastitis related to a specific pathology or with a history of recent breast trauma/laceration were excluded. Variables to determine are demographic information (age, education, marital status, etc.), diagnostic process/method, imaging findings and treatment. RESULTS: 20 patients with an average age of 32 years were included, 17 of childbearing age, and the rest at menopause. All patients had at least one full-term pregnancy and a variable lactation period. 19 presented the disease unilaterally, 60% in the left breast. Clinical presentation: 20 presented tumor, 15 erythema and 11 mastalgia. Imaging: BIRADS IVA in 12, IVB in 6 , III in 1 and II in 1. Diagnostic confirmation was performed in all patients by histopathological study. 12 received initial treatment with prednisone, 7 with antibiotics and NSAIDs, and one case with surgical excision. CONCLUSIONS: Idiopathic granulomatous mastitis is a rare benign and chronic inflammatory disease of unknown prevalence and pathogenesis. It mainly affects women of reproductive age. Imaging studies usually report nonspecific findings. It requires histopathological study to establish a definitive diagnosis, as it is a disease with diagnosis by exclusion, ideally by taking a Tru-cut biopsy. Although several therapeutic alternatives have been proposed, currently there is no universal protocol for treatment, however, resection of the lesion with wide margins associated or not with oral corticosteroids prevails as the most widely used treatment nowadays.

Mastodynia / Mastalgia

Abstract Introduction: Mastalgia is a frequent clinical symptom in general and gynecological medicine consultation. The objectives of this bibliographical review are: to define the diagnostic concept, classification and treatment of mastalgia. Methods: literature search in Pubmed, Scielo, Cochrane and Google Scholar, using the MeSH terms: mastodynia, mastalgia, breast pain, chest pain. The search limits were: full texts in English and Spanish, in humans and published during the last 10 years. Results: the physiopathology of the mastodynia is not caused by a single mechanism, but by different causes with independent pathways. The main mechanisms are hormonal, mammary density, neuropathic and extra-mammary. Conclusion: It is important to know the pathophysiology and classification of mastodynia, due to its therapeutic implications and possible association with breast cancer.

A mastalgia pré-menstrual está associada a ciclos ovulatórios / The premenstrual breast pain is associated with ovulatory cycles

Objetivo: O presente estudo teve como objetivo avaliar a associação entre o sintoma de mastalgia pré-menstrual com a existência de ciclos ovulatórios. Métodos: O estudo foi do tipo observacional, prospectivo, com corte transversal. Oitenta e cinco mulheres (85), algumas (65) com sintomas de mastalgia pré-menstrual (mastalgia cíclica), foram submetidas a um exame ultrassonográfico transvaginal com Doppler colorido, no 22º dia do ciclo menstrual (fase lútea média), para constatação da ovulação (imagem sugestiva de corpo lúteo e endométrio secretor). A seguir, foram determinados os índices de resistência arterial na periferia do corpo lúteo e no ovário contralateral. Como referência, foi usado o índice de resistência arterial de Pourcelot (RI=S-D/S). Resultados: Índices de resistência arterial significantemente mais baixos foram observados nos ovários nos quais havia ocorrido a ovulação (periferia do corpo lúteo), quando comparados com os índices de resistência das artérias ovarianas contralaterais. Todas as mulheres com sintomas de mastalgia pré-menstrual haviam ovulado, segundo os critérios da pesquisa. Conclusão: O sintoma de mastalgia pré-menstrual pode ser associado a ciclos ovulatórios.

Objective: This study aimed to evaluate the association between breast pain symptom withthe presence of ovulatory cycles. Methods: The study was observational, prospective, and crosssectional. Eight five women (85), some of them (65) with premenstrual mastalgia symptoms (cyclic mastalgia), underwent a transvaginal ultrasound with color Doppler, in the 22th day of the menstrual cycle (luteal phase), for confirmation of ovulation (suggestive image of corpus luteum and secretory endometrium). Then, it was determined the arterial resistance indexes on corpus luteum periphery and on the contralateral ovary. As a reference, we used the arterial resistance index of Pourcelot (RI=S-D/S). Results: Indices of arterial resistance significantly lower were observed in the ovaries in which ovulation had occurred (the periphery of the corpus luteum),compared with the contralateral ovarian arteries. All women with symptoms of pré-menstrual mastalgia had ovulated, according to the research criteria. Conclusion: Symptoms of premenstrual breast pain may be associated with ovulatory cycles.
