RESUMEN
RESUMEN Introducción: se sabe que las concentraciones plasmáticas de hormona antidiurética o vasopresina son más altas en las mujeres con dismenorrea primaria (DiPr) y podría ser causa de retención de agua con signos y síntomas concomitantes que agravan su cuadro clínico. La monoterapia con AINEs en ocasiones alcanza solo un alivio parcial porque no incide sobre la vasopresina. Objetivo: evaluar la eficacia y tolerabilidad del dexketoprofeno + pamabrom en la DiPr tomando como referencia el acetaminofén. Materiales y métodos: estudio doble ciego, controlado, randomizado, en pacientes con DiPr asignados al azar. Fueron aleatorizadas 172 pacientes, 86 en cada grupo 1) Grupo casos (DP): dexketoprofeno + pamabrom o 2) Grupo control (AC): acetaminofén. Se evaluó la evolución de la intensidad del dolor, el alivio del dolor, la gravedad de otros síntomas presentes y la satisfacción global del médico y paciente. Se registró las reacciones adversas. Resultados: la disminución de la intensidad del dolor, de los síntomas acompañantes y el alivio del dolor evaluados por la EVA, la PID, la SPID, el PAR y el TOTPAR respectivamente es mayor y más rápida de modo significativo en todos los tiempos para la combinación DP. Las reacciones adversas fueron mínimas. La satisfacción global de pacientes y médicos respecto al tratamiento es significativa a favor de la combinación DP. Conclusiones: dexketoprofeno + pamabrom es significativamente más eficaz y rápido en el control del dolor y otros síntomas presentes en la dismenorrea primaria que acetaminofén demostrando la validez de añadir un diurético suave a un AINE para incrementar su eficacia. El tratamiento DP es bien tolerado (AU).
ABSTRACT Background: It is known that plasma concentrations of antidiuretic hormone or vasopressin are higher in women with primary dysmenorrhea (DiPr) and could cause water retention with concomitant signs and symptoms that aggravate the illness. Monotherapy with NSAIDs sometimes achieves only partial relief because it does not affect vasopressin. Objective: The aim was to evaluate the efficacy and tolerability of dexketoprofen + pamabrom in DiPr taking as reference acetaminophen. Materials and methods: Double-blind, controlled, randomized study in patients with DiPr random to 1) Case group (PD): dexketoprofen + pamabrom or 2) Control group (CA): acetaminophen. The evolution of pain intensity, pain relief, severity of other present symptoms and overall satisfaction of the doctor and patient were evaluated. Adverse reactions were recorded. Results: 172 patients were randomized, 86 in each group. The decrease in pain intensity, accompanying symptoms and pain relief evaluated by VAS, PID, SPID, PAR and TOTPAR respectively is significantly greater and faster at all times for the combination DP. Adverse reactions were minimal. The overall satisfaction of patients and doctors regarding treatment is significant in favor of the DP combination. Conclusions: Dexketoprofen + pamabrom is significantly more effective and faster in the control of pain and other symptoms present in primary dysmenorrhea than acetaminophen demonstrating the validity of adding a mild diuretic to an NSAID to increase its effectiveness. DP treatment is well tolerated (AU).

To develop a machine learning model to investigate the discriminative power of whole-brain gray-matter (GM) images derived from primary dysmenorrhea (PDM) women and healthy controls (HCs) during the pain-free phase and further evaluate the predictive ability of contributing features in predicting the variance in menstrual pain intensity. Sixty patients with PDM and 54 matched female HCs were recruited from the local university. All participants underwent the head and pelvic magnetic resonance imaging scans to calculate GM volume and myometrium-apparent diffusion coefficient (ADC) during their periovulatory phase. Questionnaire assessment was also conducted. A support vector machine algorithm was used to develop the classification model. The significance of model performance was determined by the permutation test. Multiple regression analysis was implemented to explore the relationship between discriminative features and intensity of menstrual pain. Demographics and myometrium ADC-based classifications failed to pass the permutation tests. Brain-based classification results demonstrated that 75.44% of subjects were correctly classified, with 83.33% identification of the patients with PDM (P < 0.001). In the regression analysis, demographical indicators and myometrium ADC accounted for a total of 29.37% of the variance in pain intensity. After regressing out these factors, GM features explained 60.33% of the remaining variance. Our results suggested that GM volume can be used to discriminate patients with PDM and HCs during the pain-free phase, and neuroimaging features can further predict the variance in the intensity of menstrual pain, which may provide a potential imaging marker for the assessment of menstrual pain intervention.

Endometriosis (EM) occurring in adolescents presents distinct clinical and histologic characteristics compared to the disease in women. Because the symptoms of EM are nonspecific, often overlapping with those experienced in a range of gynecological and gastrointestinal conditions, the process of reaching a diagnosis of EM is often delayed. The diagnosis of EM is suspected depending on the history and the symptoms and signs, is corroborated by physical examination and imaging techniques, and is finally proved by histological examination of specimens collected during laparoscopy. Currently, there is insufficient evidence to make strong recommendations for management in adolescents who may have EM. This short report reviews some peculiarities of EM in adolescents and provides an update of recent knowledge of the diagnosis and treatment of EM. We hope that the present contribution may help to bring more attention to the clinical diagnosis of EM and consequently aid in decreasing diagnostic delay.

OBJECTIVE: To investigate the relationship between primary dysmenorrhea (PD) and orthodontic pain in female patients, and to test the hypothesis that the intensity and duration of orthodontic pain could be roughly predicted by severity of PD. MATERIALS AND METHODS: One hundred twenty college females were enrolled and put into one of three groups-mild (Mi), moderate (Mo), or severe (S)-according to level of menstrual pain. Intensity of the orthodontic pain was measured by visual analog scale (VAS) on days 1, 2, 4, 7, 14, and 28 after archwire placement. RESULTS: As the intensity of orthodontic pain declined with time, the three groups demonstrated different changes during the initial week. Mi had the lowest VAS scores, whereas S possessed the highest scores. In contrast, Mo stayed in between. Significantly positive correlations were found between the severity of PD and the intensity of orthodontic pain at each time point within the first 2 weeks. In addition, though the majority of subjects reported disappearance of pain by the end of the second week in both Mi and Mo, a large proportion of females still perceived pain in S. CONCLUSION: Females with higher levels of menstrual pain tended to perceive orthodontic pain with higher intensity and more prolonged duration. Thus, PD could potentially serve as a reference to predict orthodontic pain in clinical settings.

PURPOSE: to present a series of cases of membranous dysmenorrhea. METHODS: all the patients selected were under diagnostic suspicion, after being clinically attended in a private medical office due to the report of painful dysmenorrhea associated with spontaneous elimination of elastic material with uterine shape. Only relevant facts about the pain condition have been described, together with the present and previous medical history and life habits. The material eliminated was forwarded to the pathology laboratory, where the macro and microscopic analyses were done. Cases with no confirmation of membranous material elimination were not selected. After the diagnostic confirmation, literature up to 2008 was carried out using the MeSH method, with the words 'membranous dysmenorrheal'. RESULTS: three cases of dysmenorrhea were transcribed. Besides the characteristic picture of pain and vaginal elimination of elastic material, all the cases were associated with the use of hormonal contraceptive methods. CONCLUSIONS: despite the fact that there are only sporadic reports of cases of membranous dysmenorrhea in the scientific literature, this etiology must be considered in cases of pain associated with vaginal bleeding plus elimination of elastic or solid material. The final diagnosis depends on anatomopathological exam, which should not be dismissed. We highlight the need for more discussion about this pathology, to keep the professionals updated with the aim of exerting adequate diagnosis and therapeutics.

OBJETIVO: apresentar uma série de casos de dismenorreia membranosa. MÉTODOS: todas as pacientes foram selecionadas a partir da suspeição diagnóstica, após atendimento clínico em consultório privado por relato de dismenorreia dolorosa associada à eliminação espontânea de material elástico com formato semelhante a útero. Apenas fatos relevantes foram descritos do quadro álgico, história médica atual e pregressa e hábitos de vida. O material eliminado foi encaminhado para laboratório de patologia no qual ocorreu a análise macro e microscópica. Os casos em que não se pode provar a eliminação de material com característica membranácea não foram selecionados. Após a confirmação diagnóstica, realizou-se uma revisão da literatura até o ano de 2008 utilizando o método MeSH com o termo "membranous dysmenorrhea". RESULTADOS: três casos clínicos de dismenorreia foram transcritos. Todos os casos, além do quadro característico de dor e eliminação vaginal de material elástico, foram associados ao uso de métodos anticoncepcionais hormonais. CONCLUSÕES: embora haja apenas escassos relatos de caso de dismenorreia membranosa na literatura científica, sua etiologia deve ser suspeita em casos de dor associada a sangramento vaginal com eliminação de material elástico ou firme. O diagnóstico final é dependente do exame anatomopatológico que nunca deve ser dispensado. Observamos necessidade de mais discussões sobre esta patologia com o objetivo de manter o profissional atualizado para exercer diagnóstico e terapêutica adequados.

OBJECTIVE: To explore the extent to which traditional Chinese medicine (TCM) diagnostic categories for primary dysmenorrhoea are useful in describing the clinical presentation of this condition in Australian women in comparison with Chinese women, and therefore the potential usefulness of these categories in guiding TCM treatment of Australian women. DESIGN AND SETTING: A comparative study of 120 Australian and 122 Chinese women aged from 18 to 45 years with primary dysmenorrhoea. MAIN OUTCOME MEASURES: Modified valid TCM diagnostic protocol. RESULTS: Difference in menstruation and menstrual pain profiles between the two groups of women found in the same study did not translate into differences in the underlying syndrome according to TCM diagnostic categories. The study found that Australian and Chinese women were represented in broadly similar proportions across the defined five diagnostic categories. CONCLUSION: Some evidence suggests that although the clinical presentation of symptoms in Australian and Chinese women is different, the distribution of women across the diagnostic categories in TCM is similar. Therefore, the TCM protocol used to diagnose primary dysmenorrhoea and guide treatment is unlikely to require adaptation for use with Australian women.

BACKGROUND: Dysmenorrhea is the leading cause of short-term school absenteeism. It is associated with a negative impact on social, academic, and sports activities of many female adolescents. Dysmenorrhea has not previously been described among Hispanic adolescents, the fastest growing minority group in the United States. OBJECTIVE: To determine the prevalence of dysmenorrhea among Hispanic female adolescents; its impact on academic performance, school attendance, and sports and social activities; and its management. PARTICIPANTS AND METHODS: A total of 706 Hispanic female adolescents, in grades 9 through 12, completed a 31-item questionnaire about the presence, duration, severity, treatment, and limitations of dysmenorrhea at a local urban high school. RESULTS: Among participants who had had a period in the previous 3 months, 85% reported dysmenorrhea. Of these, 38% reported missing school due to dysmenorrhea during the 3 months prior to the survey and 33% reported missing individual classes. Activities affected by dysmenorrhea included class concentration (59%), sports (51%), class participation (50%), socialization (46%), homework (35%), test-taking skills (36%), and grades (29%). Treatments taken for dysmenorrhea included rest (58%), medications (52%), heating pad (26%), tea (20%), exercise (15%), and herbs (7%). Fourteen percent consulted a physician and 49% saw a school nurse for help with their symptoms. Menstrual pain was significantly associated with school absenteeism and decreased academic performance, sports participation, and socialization with peers (P<.01). CONCLUSIONS: Dysmenorrhea is highly prevalent among Hispanic adolescents and is related to school absenteeism and limitations on social, academic, and sports activities. Given that most adolescents do not seek medical advice for dysmenorrhea, health care providers should screen routinely for dysmenorrhea and offer treatment. As dysmenorrhea reportedly affects school performance and attendance, school administrators may have a vested interest in providing health education on this topic to their students.

La dismenorrea es la menstruación dolorosa de variable intensidad que puede asociarse a malestar general, cefalea, náuseas y vómitos. Afecta en algún período de la vida al 50 por ciento de la población femenina(especialmente adolescentes y adultos jóvenes). Disminuye su frecuencia con el uso de anticonceptivos orales y luego de partos vaginales. La dismenorrea puede ser primaria en la que no existe patología ginecológica orgánica y secundaria sea a afecciones ginecológicas (malformaciones, adenomiosis, endometriosis, etc.) o no ginecológicas(pélvicas, musculoesquelético, etc). Clínicamente la dismenorrea se clasifica en grado de 1 a 4 según la intensidad y su respuesta a los antinflamatorios

OBJECTIVE: Increased intra-uterine pressure due to exaggerated myometrial contractions is an important factor in the pathogenesis of dysmenorrhea, its treatment being associated with uterine muscle relaxation. Diminished synthesis of endogenous nitric oxide has been shown to induce myometrial contractions and, conversely, the administration of exogenous nitric oxide has successfully resulted in uterine relaxation in a variety of obstetrical/gynecological disorders. The objective of this study was to determine the role of transdermal glyceryl trinitrate, as a source of exogenous nitric oxide, in the management of primary dysmenorrhea. METHOD: This was a multi-national, double-blind, randomized and cross-over study in patients with primary dysmenorrhea. Eighty-eight patients from six countries were evaluated during three menstrual cycles while receiving glyceryl trinitrate patches, 0.1 mg/h (x) or matching placebo patches. Pain intensity scores assessed on a visual analog scale and the time-weighted sum of the pain intensity differences (SPID) were evaluated during days 1, 2 and 3 of each cycle using an analysis of variance (ANOVA) model. Overall assessment of efficacy and the incidence of adverse events were analyzed by the Stuart-Maxwell or the McNemar tests as appropriate. RESULTS: Efficacy was determined for the first day of each cycle, all days/all cycles and for patients who completed at least one cycle in each treatment modality. In all three analyses, SPIDs were statistically superior (P<0.01) for the glyceryl trinitrate patches. Pain intensity differences from hours 1 to 6 also showed statistically significant differences in favor of the active treatment. In the overall assessment of efficacy, glyceryl trinitrate patches were statistically superior as well. The incidence of headache was 26% for the active drug and 6.1% for placebo (P<0.01). CONCLUSIONS: The data indicate that transdermal glyceryl trinitrate, as a source of exogenous nitric oxide, is useful as a modulator of uterine contractility representing, therefore, a new and mechanistically different therapeutic alternative for the management of primary dysmenorrhea.

Dysmenorrhea affects over 50% of menstruating women and causes extensive personal and public health problems, a high degree of absenteeism and severe economic loss. In primary dysmenorrhea there is no macroscopically identifiable pelvic pathology, while in secondary dysmenorrhea gross pathology is present in the pelvic structures. With primary dysmenorrhea the pain is suprapubic and spasmodic, and associated symptoms may be present. Characteristically dysmenorrhea starts at or shortly after menarche. The pain lasts for 48-72 hours during the menstrual flow and is most severe during the first or second day of menstruation. It is now clear that in many women with primary dysmenorrhea the pathophysiology is due to increased and/or abnormal uterine activity because of the excessive production and release of uterine prostaglandins. Treatment with many of the prostaglandin synthetase inhibitors (nonsteroidal antiinflammatory drugs) will produce significant relief from dysmenorrhea and a concomitant decrease in menstrual fluid prostaglandins. For dysmenorrheic women who desire oral contraception, this agent will relieve the dysmenorrhea by suppressing endometrial growth, thus resulting in a decrease in the menstrual flow as well as in menstrual fluid prostaglandins. For those not requiring oral contraception the drug of choice for primary dysmenorrhea remains a prostaglandin inhibitor. Laparoscopy need be resorted to only if a pelvic abnormality is detected on examination or if treatment with prostaglandin inhibitors for up to six months is not significantly effective. In secondary dysmenorrhea, relief is obtained when the pelvic pathology--such as ovarian cysts, uterine fibroids, adhesions, cervical stenosis, congenital malformation of the uterus and endometriosis--is treated. In women using IUDs the dysmenorrhea is readily controlled with prostaglandin inhibitors since the underlying pathophysiology is excessive prostaglandin production and release.
