Severe hemorrhagic corpus luteum complicating anticoagulation in antiphospholipid syndrome

Antiphospholipid syndrome (APS) is a disorder of coagulation that causes thrombosis as well as pregnancy-related complications, occurring due to the autoimmune production of antibodies against phospholipid. Full anticoagulation is the cornerstone therapy in patients with thrombosis history, and this can lead to major bleeding. During a 3-year period, 300 primary and secondary APS patients were followed up at the Rheumatology Division of the authors` University Hospital. Of them, 255 (85%) were women and 180 (60%) were of reproductive age. Three of them (1%) had severe hemorrhagic corpus luteum while receiving long-term anticoagulation treatment and are described in this report. All of them were taking warfarin, had elevated international normalized ratio (> 4.0) and required prompt blood transfusion and emergency surgery. Therefore, we strongly recommend that all women with APS under anticoagulation should have ovulation suppressed with either intramuscular depot-medroxyprogesterone acetate or oral desogestrel.

Hormonal Contraceptives and the Length of Their Use Are Not Independent Risk Factors for High-Risk HPV Infections or High-Grade CIN

Aims: To evaluate the role of hormonal contraceptives as a risk factor of high-risk human papillomavirus (HR-HPV), cervical intraepithelial lesions (CIN) and cervical cancer in our multi-center population-based LAMS (Latin American Screening) study. Methods: A cohort study with >12,000 women from Brazil and Argentina using logistic regression to analyze the covariates of hormonal contraception (HOC - oral, injections, patches, implants, vaginal ring and progesterone intrauterine system) use followed by multivariate modeling for predictors of HR-HPV and CIN2+. Results: HR-HPV infection was a consistent risk factor of high-grade CIN in all three groups of women. The length of HOC use was not significantly related to high-grade squamous intraepithelial lesions (HSIL)+ Pap (p = 0.069), LSIL+ Pap (p = 0.781) or ASCUS+ (p = 0.231). The same was true with the length of HOC use and histology CIN3+ (p = 0.115) and CIN2+ (p = 0.515). Frequently, HOC users have previously shown more HPV-related lesions, as well as lower HPV prevalence if they were current smokers. But HOC use and time of usage were not independent risk factors of either HR-HPV infection or high-grade CIN using multiple logistic regressions. Conclusions: No evidence was found for an association between the use of HOC with an increased risk for HR-HPV infection or high-grade CIN in this cohort. Copyright (C) 2010 S. Karger AG, Basel

Effect of low-dose combined oral contraceptive on aerobic capacity and anaerobic threshold level in active and sedentary young women

Background: The purpose of this study was to evaluate the effect of long-term use of oral contraceptives (DC) containing 0.20 mg of ethinylestradiol (EE) combined with 0.15 mg of gestodene (GEST) on the peak aerobic capacity and at the anaerobic threshold (AT) level in active and sedentary young women. Study Design: Eighty-eight women (23 +/- 2.1 years old) were divided into four groups active-OC (G1), active-NOC (G2), sedentary-OC (G3) and sedentary-NOC (G4) and were submitted to a continuous ergospirometric incremental test on a cycloergometer with 20 to 25 W min(-1) increments. Data were analyzed by two-way ANOVA with Tukey post hoc test. Level of significance was set at 5%. Results: The OC use effect for the variables relative and absolute oxygen uptake VO(2) mL kg(-1) min(-1); VO(2), L min(-1), respectively), carbon dioxide output (VCO(2), L min(-1)), ventilation (VE, L min(-1)), heart rate (HR, bpm), respiratory exchange ratio (RER) and power output (W) data, as well as the interaction between OC use and exercise effect on the peak of test and at the AT level did not differ significantly between the active groups (G1 and G2) and the sedentary groups (G3 and G4). As to the exercise effect, for all variables studied, it was noted that the active groups presented higher values for the variables VO(2), VCO(2), VE and power output (p<.05) than the sedentary groups. The RER and HR were similar (p>.05) at the peak and at the AT level between G1 vs. G3 and G2 vs. G4. Conclusions: Long-term use of OC containing EE 0.20 mg plus GEST 0.15 mg does not affect aerobic capacity at the peak and at the AT level of exercise tests. (C) 2010 Elsevier Inc.

Influence of third-generation oral contraceptives on the complexity analysis and symbolic dynamics of heart rate variability

Objective To evaluate the influence of oral contraceptives (OCs) containing 20 mu mu g ethinylestradiol (EE) and 150 mu mu g gestodene (GEST) on the autonomic modulation of heart rate (HR) in women. Methods One-hundred and fifty-five women aged 24 +/-+/- 2 years were divided into four groups according to their physical activity and the use or not of an OC: active-OC, active-non-OC (NOC), sedentary-OC, and sedentary-NOC. The heart rate was registered in real time based on the electrocardiogram signal for 15 minutes, in the supine-position. The heart rate variability (HRV) was analysed using Shannon`s entropy (SE), conditional entropy (complexity index [CInd] and normalised CInd [NCI]), and symbolic analysis (0V%, 1V%, 2LV%, and 2ULV%). For statistical analysis the Kruskal-Wallis test with Dunn post hoc and the Wilcoxon test (p < 0.05 was considered significant) were applied. Results Treatment with this COC caused no significant changes in SE, CInd, NCI, or symbolic analysis in either active or sedentary groups. Active groups presented higher values for SE and 2ULV%, and lower values for 0V% when compared to sedentary groups (p < 0.05). Conclusion HRV patterns differed depending on life style; the non-linear method applied was highly reliable for identifying these changes. The use of OCs containing 20 mu mu g EE and 150 mu mu g GEST does not influence HR autonomic modulation.

Effects of the levonorgestrel-releasing intrauterine system on cardiovascular risk markers in patients with endometriosis: a comparative study with the GnRH analogue

Background: The study was conducted to evaluate the cardiovascular risk markers associated with endometriosis and the influence of the levonorgestrel intrauterine system (LNG-TUS) compared with the GnRH analogue (GnRHa) leuprolide acetate on these risk markers after 6 months of treatment. Study Design: This was a randomized, prospective, open clinical Study, with 44 patients with laparoscopically and histologically confirmed endometriosis. Patients were randomized into two groups: the LNG-IUS group, composed of 22 patients who underwent LNG-IUS insertion., and the GnRHa group, composed of 22 patients who received a monthly GnRHa injection for 6 months. Body mass index systolic and diastolic arterial blood pressure; heart rate; and laboratory cardiovascular risk markers such as interlelikin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), C-reactive protein (CRP), homocysteine (HMC), lipid profile, total leukocytes and vascular cell adhesion molecule (VCAM) were measured before and 6 months after treatment. Results: After 6 months of treatment, a significant reduction in pain score occurred in both groups with no significant difference in improvement between the two medications evaluated. In the LNG-IUS group, from pretreatment to posttreatment period, there was a significant reduction in the levels (mean +/- SD) of VCAM (92.8 +/- 4.2 to 91.2 +/- 2.7 ng/mL, p=.04), CRP (0.38 +/- 0.30 to 0.28 +/- 0.21 mg/dL, p=.03), total cholesterol (247.0 +/- 85.0 to 180.0 +/- 31.0 mg/dL, p=.0002), triglycerides (118.0 +/- 76.0 to 86.5 +/- 41.5 mg/dL, p=.003), low-density lipoprotein cholesterol (160.5 +/- 66.0 to 114.5 +/- 25.5 mg/dL, p=.0005) and high-density lipoprotein cholesterol (63.0 +/- 20.5 to 48.5 +/- 10.5 mg/dL, p=.002). The GnRHa group showed an increase in HMC levels (11.5 +/- 2.9 to 13.0 +/- 2.7 mu mol/L, p=.04) and a reduction in IL-6 levels (4.3 +/- 3.9 to 2.3 +/- 0.8 pg/mL, p=.005), VCAM (94.0 +/- 3.8 to 92.0 +/- 1.6 ng/mL, p=.03) and total leukocytes (7330 +/- 2554 to 6350 +/- 1778, p=.01). In the GnRH group, the remaining variables, including lipid profile, did not show any statistical difference. Conclusions: This study shows that some cardiovascular risk markers are influenced by both GnRHa and the LNG-TUS, but the latter had a greater positive impact on the lipid profile, which could lead to a favorable effect during long-term treatment.

Safety of the etonogestrel-releasing implant during the immediate postpartum period: a pilot study

Background: The effects of etonogestrel (ETG)-releasing contraceptive implant during the immediate postpartum period on maternal safety are unknown. Study design: Forty healthy women exclusively breastfeeding were randomized to receive either ETG-releasing implant 24-48 h after delivery (n=20) or depot medroxyprogesterone acetate (DMPA group; n=20) at the sixth week postpartum. We measured blood pressure, maternal and neonatal weight, body mass index (BMI; kg/m(2)), waist circumference (WC), complete blood count, C-reactive protein, interleukin-6, tumor necrosis factor (TNF-alpha), lipid profile, fasting serum glucose and maintenance of exclusive lactation up to the 12th week postpartum. Results: Decreases in mean maternal weight, BMI (kg/m(2)) and WC were significantly greater in the ETG-releasing implant group than in the MPA group during the first 6 weeks postpartum (-4.64 +/- 2.71 kg vs. -2.6 +/- 2.45 kg mean +/- SD, p=.017; -1.77 +/- 1.06 kg/m(2) vs. -0.97 +/- 0.95 kg/m(2), p=.026; -15.3 +/- 6.72 cm vs. -9.05 +/- 5.84 cm, p=.003, respectively). In addition, total cholesterol and HDL, were lower in DMPA users, and TNF-alpha and leukocytes were higher in DMPA users compared to in the implant group, between 6 and 12 weeks after delivery. The newborns of implant users showed a trend towards gaining more weight, as compared with the infants of the DMPA mothers during the first 6 weeks of life (implant group: +1460.50 +/- 621.34 g vs. DMPA group: +1035.0 +/- 562.43 g, p=.05). The remaining variables, including the duration of exclusive breastfeeding, were similar between the groups. Conclusion: The insertion of ETG-releasing contraceptive implant during the immediate postpartum period was not associated with deleterious maternal clinical effects or with significant maternal metabolic alterations or decreased infant weight gain.

Both a combined oral contraceptive and depot medroxyprogesterone acetate impair endothelial function in young women

Background: The study was conducted to determine whether the use of a combined oral contraceptive (COC) or depot medroxyprogesterone acetate (DMPA) interferes with endothelial function. Study Design: The study was conducted on 100 women between the ages of 18 and 30 years. Fifty women had not used hormonal contraception (control group) for at least 12 months, 25 were current users of a COC (ethinylestradiol 30 mcg+levonorgestrel 150 mcg) and 25 were current users of DMPA (150 mg) for at least a 6-month period. All women were evaluated for brachial flow-mediated dilation (FMD), intima-media thickness, carotid distensibility and stiffness index, arterial pressure, body mass index, waist circumference, heart rate and lipid profile. Results: A significant difference in FMD was observed between the COC and control groups (6.4 +/- 2.2% vs. 8,7 +/- 3.4%, p<.01) and between the DMPA and control groups (6.2 +/- 2.1% vs. 8.7 +/- 3.4%, p<.01). The DMPA group had lower values of total cholesterol (TC) and low-density lipoprotein (LDL-C) than COC users and the control group (TC: DMPA=139.9 +/- 21.5 mg/dL vs. controls=167.1 +/- 29.2 mg/dL vs. COC=168.2 +/- 37.5. p=.001; LDL-C: DMPA-85.3 +/- 20.1 mg/dL vs. controls=102 +/- 24.5 mg/dL vs. COC=106.7 +/- 33.3 mg/dL, p=.01). The control group had higher levels of high-density lipoprotein (HDL-C) than the DMPA and COC groups (controls=52.4 +/- 14.1 mg/dL vs. DMPA=42.2 +/- 7.2 mg/dL vs. COC=45.4 +/- 9.1 mg/dL, p=.001). No significant differences were observed regarding the other variables. Conclusions: FMD was lower among COC and DMPA users, Suggesting that these hormonal contraceptives may promote endothelial dysfunction. (C) 2009 Elsevier Inc. All rights reserved.

Braquiterapia prostática: morbilidade urinária e sexual

RESUMO: Objectivos 1. Avaliar a morbilidade urinária e sexual secundária à braquiterapia prostática com implante de I125. 2. Avaliar a influência da hormonoterapia neoadjuvante e adjuvante na morbilidade urinária e sexual secundária à braquiterapia(I125). 3. Avaliar a influência da associação da radioterapia externa na morbilidade urinária e sexual secundária à braquiterapia(I125). 4. Avaliar a morbilidade urinária dos doentes com contra-indicação relativa (próstatas volumosas, IPSS elevado).Material e métodos De Setembro de 2000 a Dezembro de 2004 foram recrutados 204 doentes com o diagnóstico de carcinoma da próstata localizado (T1 e T2) ou localmente avançado (T3) e expectativa de vida superior a 10 anos. Foram submetidos a braquiterapia, com implante transperineal de Iodo 125 (I125) em monoterapia ou combinada com hormonoterapia e/ou radioterapia externa (tratamento trimodal). Definiram-se diversos sub-grupos de pacientes, consoante algumas características habitualmente referidas como factores de risco para a morbilidade do tratamento de braquiterapia prostática, com o objectivo de analisar a sua influência sobre a morbilidade urinária e sexual: Grupo 1: Braquiterapia em monoterapia (MONO) versus braquiterapia associada a radioterapia externa (BCOMB) Grupo 2: Próstatas volumosas (>50ml) versus próstatas não volumosas (<50ml)Grupo 3: Braquiterapia associada a hormonoterapia (HORM) versus braquiterapia sem hormonoterapia (NHORM)Grupo 4: IPSS elevado versus IPSS baixo Avaliou-se a evolução do IPSS, QoL, taxa de RTU-P e retenção urinária pós implante, e evolução do BSFI durante todo o período de seguimento. Resultados Grupo 1: Para o grupo MONO o IPSS iniciou-se com 7.1, sofreu agravamento para 16.1 e 15.9 ao primeiro e terceiro meses. Aos 12 meses, o IPSS desceu para 10.1 enquanto que, aos 18 e 24 meses, o IPSS foi de 7.3 e 5.8. O grupo BCOMB iniciou com IPSS de 9.4. Sofreu agravamento ligeiro e pouco acentuado até aos 6 meses (IPSS de 14). A evolução do IPSS foi, então, flutuante com IPSS de 5.9 aos 12 meses e 9.5 aos 18 meses. Aos 24 meses apresentava IPSS de 6.7. A taxa de retenção urinária (6.4% e 0%) e de RTU-P (2.0% e 0%) foram semelhantes nos grupos MONO e BCOMB, respectivamente (p=0.375 e p=1). A evolução da qualidade das erecções foi semelhante nos dois grupos excepto aos 6 meses em que MONO apresentou o valor 6 e BCOMB 3.7 (p=0.029). A percentagem de doentes potentes foi significativamente inferior nos primeiros 6 meses após a braquiterapia para o grupo BCOMB relativamente ao grupo MONO: 36%–74%; 33%–73%; 33%–75%. Após os 6 meses os grupos foram homogéneos. Grupo 2: O IPSS evoluiu nas próstatas <50ml e >50ml de 7–9 para 15-19 ao primeiro mês e 15-18 ao 3.º mês. Apenas ao primeiro mês é que as diferenças no IPSS foram significativas (p=0.061). Após o 3.º mês os dois grupos foram semelhantes: IPSS de 8 e 12 ao 12.º mês e 5.7 e 6 ao 24.º mês. As taxas de retenção urinária e de RTU-P foram semelhantes (p=0.054 e p=0.286) Grupo 3: A evolução do IPSS, taxas de retenção urinária e de RTU-P foram sobreponíveis em ambos os grupos. A evolução da líbido, erecções, percentagem de doentes potentes, ejaculação, incómodo e satisfação foi significativamente inferior no grupo HORM relativamente ao grupo N HORM apenas ao primeiro mês (valores de p<0.0001; <0.0001; < 0.0001; 0.009 e 0.002 respectivamente) Grupo 4: A evolução do IPSS nos doentes com IPSS elevado foi a seguinte: 22.17(0M); 19.5(1M); 20.5(3M); 15.3(6M); 15.7(12M); 11(18M); 8(24M) A evolução do IPSS nos doentes com IPSS baixo foi a seguinte: 5.9(0M); 15.3(1M); 14.9(3M); 12.2(6M); 8.9(12M); 7.2(18M), 5.5(24M) As taxas de RTU-P (2.8% e 0%) e retenção urinária (5.1% e 5.9%) foram semelhantes em ambos os grupos de doentes (p=1). Conclusões 1. A radioterapia intersticial da próstata com implante transperineal e ecoguiado de Iodo 125 é frequentemente acompanhada de morbilidade urinária transitória e de intensidade moderada. A Morbilidade consiste em sintomatologia do aparelho urinário baixo (“LUTS – lower urinary tract symptoms”) que, na maioria dos doentes, sofre um agravamento máximo do primeiro ao 3.º mês. Segue-se uma melhoria ligeira até ao 6.º mês que é mais acentuada daí em diante. Por volta do 12.º e 18.º mês, a maior parte dos doentes apresenta sintomatologia urinária muito semelhante à que apresentava antes do tratamento. Após o 18.º mês, os doentes mantêm uma melhoria da sintomatologia urinária para além da que apresentavam previamente ao implante. As taxas de retenção urinária e de ressecção transuretral prostática após o implante de braquiterapia são muito baixas, inferiores a 10%. 2. A associação da braquiterapia prostática com radioterapia externa adjuvante influencia a evolução da sintomatologia urinária: o aparecimento da sintomatologia urinária é mais lento, demorando 6 meses a atingir o seu valor máximo que, por sua vez, é de intensidade menos acentuada do que quando a braquiterapia é utilizada em monoterapia. 3. O volume prostático superior a 50 ml não influencia a morbilidade urinária. 4. A terapêutica hormonal, neoadjuvante e adjuvante, não influencia a sintomatologia urinária. 5. Os doentes com sintomatologia urinária prévia muito acentuada não sofrem agravamento da referida sintomatologia. Pelo contrário, apresentam uma melhoria de sintomas urinários desde o primeiro mês, e que se mantém ao longo dos 24 meses de seguimento, apresentando, no final deste período, sintomatologia urinária ligeira e muito inferior à que apresentavam antes do implante. As taxas de retenção urinária e RTU-P após a braquiterapia são semelhantes às que ocorrem nos doentes assintomáticos previamente ao implante. 6. A vida sexual está preservada, em mais de 70% dos casos, ao fim dos 24 meses de seguimento. No entanto, imediatamente após o primeiro mês de seguimento, ocorre uma diminuição ligeira da qualidade das erecções que se mantém, sem melhoria ou agravamento, durante todo o período de seguimento. A hormonoterapia afecta todos os parâmetros da vida sexual, embora de forma apenas temporária. Após a suspensão da terapêutica hormonal este grupo de doentes recupera a actividade sexual e apresenta-se idêntico ao grupo de doentes que não foram sujeitos a essa terapêutica.----------------ABSTRACT: Objectives 1. To assess urinary and sexual morbility after prostatic brachytherapy with the implant of I125 seeds. 2. To assess the influence of neoadjuvant and adjuvant hormone therapy in urinary and sexual morbility after prostatic brachytherapy with the implant of I125 seeds. 3. To assess the effects, on urinary and sexual morbility, of associating external radiotherapy after prostatic brachytherapy with the implant of I125 seeds. 4. To assess the urinary morbility in patients with relative contraindications (voluminous prostates, high IPSS). Material and Methods From September, 2000 to December, 2004 a total of 204 patients were recruited with a diagnosis of localized (T1 and T2) or locally advanced (T3) carcinoma of the prostate and a life expectancy in excess of 10 years. The patients underwent brachytherapy with transperineal seed implant of iodine (I125) as a monotherapy or in combination with hormone therapy and/or external radiotherapy (trimodal treatment). With the aim of evaluating the treatment’s influence on urinary and sexual morbility, a number of patient sub-groups were defined in accordance with certain characteristics normally mentioned as morbility risk factors for prostatic brachytherapy treatment: Group 1: Brachytherapy as monotherapy (MONO) versus brachytherapy in combination with external radiotherapy (BCOMB) Group 2: Voluminous prostates (>50ml) versus non- voluminous prostates (<50ml) Group 3: Brachytherapy in combination with hormone therapy (HORM) versus brachytherapy without hormone therapy (NHORM)Group 4: High IPSS versus a low IPSS. The evolution of the IPSS, QoL, TURP rate and post-implant urinary retention as well as the BSFI were assessed throughout the entire follow-up period. Results Group 1: For the MONO group the IPSS began at 7.1, and then rose to 16.1 and 15.9 in the first and third months, respectively. At month 12, the IPSS had dropped to 10.1 and at month 18 and 24 the IPSS was registered at 7.3 and 5.8, respectively. The BCOMB group started out with an IPSS of 9.4. It underwent a slight and little-significant rise until month 6 (IPSS at 14). The evolution of the IPSS then began to fluctuate from an IPSS of 5.9 at month 12 and 9.5 at month 18. At month 24 we registered an IPSS of 6.7. The urinary retention rate (6.4% and 0%) and TURP rate (2.0% e 0%) were similar to those of the MONO and BCOMB groups, respectively (p=0.375 and p=1). The evolution regarding the quality of erections was similar for the two groups except at 6 months when the MONO group displayed a value of 6 and the BCOMB group 3.7 (p=0.029). The percentage of sexually potent patients was significantly lower in the first six months after brachytherapy for the BCOMB group when compared with the MONO group: 36%–74%; 33%–73%; 33%–75%. After six months, the results became more consistent. Group 2: IPSS results evolved in <50ml and >50ml prostates from 7–9 to 15-19 in the first month and from 15-18 after the third month. It was only in the first month that the differences in the IPSS were significant (p=0.061). After the third month, the two groups displayed similar outcomes: IPSS 8 and 12 at month 12 and 5.7 and 6 at month 24. Urinary retention and TURP rates were similar (p=0.054 e p=0.286). Group 3: IPSS evolution and rates of urinary retention and TURP were identical in both groups. Figures regarding libido, erections, percentage of sexually potent patients, ejaculation, discomfort and sexual satisfaction were always significantly lower for the HORM group, when compared to the NHORM group in the first month only (values of p<0.0001; <0.0001; <0.0001; 0.009 e 0.002, respectively). Group 4: IPSS evolution in patients with a high IPSS was as follows: 22.17(0M); 19.5(1M); 20.5(3M); 15.3(6M); 15.7(12M); 11(18M); 8(24M) IPSS evolution in patients with a low IPSS was as follows: 5.9(0M); 15.3(1M); 14.9(3M); 12.2(6M); 8.9(12M); 7.2(18M), 5.5(24M)TURP rates (2.8% e 0%) and those for urinary retention (5.1% e 5.9%) were similar in both patient groups (p=1). Conclusions 1. Interstitial radiotherapy of the prostate with transperineal, ultrasound-guided implant of Iodine-125 seeds is often followed by transitory urinary morbility of moderate intensity. The morbility involves symptoms of the lower urinary tract which, in most cases are at their worst from the first to the third months. There is a slight improvement up to the sixth month, at which point improvement becomes more accentuated. Around months 12 or 18, most patients display urinary symptoms that are very similar to those noted before treatment. After month 18, patients’ urinary symptoms continue to improve past the point they displayed prior to the implant. Urinary retention rates and those for transurethral resection of the prostate are very low (below 10%), after brachytherapy seed implant. 2. The combination of prostatic brachytherapy and adjuvant external radiotherapy affects the evolution of urinary symptoms: the appearance of urinary symptoms is much slower, taking six months to peak, and is less intense than when brachytherapy is employed as the only means of treatment. 3. The fact that the prostate displays a volume greater than 50 ml does not influence urinary morbility. 4. Neoadjuvant and adjuvant hormone therapy do not influence urinary symptomology. 5. Patients with severe, preexisting symptoms of the urinary tract do not experience a worsening of those symptoms. On the contrary, they exhibit an improvement in urinary symptoms as of the first month. This improvement continues for the 24 months, after which patients display symptoms of the urinary tract that are slight and a noticeable improvement over the urinary complaints registered before the implant. Urinary retention and TURP rates subsequent to brachytherapy are similar to those registered for asymptomatic patients. 6. The patient’s sexual performance is maintained in more than 70% of the cases, as noted after 24 months of follow-up. However, immediately after the first follow-up month there is a lessening in the quality of erections that continues, without improving or worsening, for the whole follow-up period. Hormone therapy affects all the parameters of sexual performance, albeit temporarily. After suspending hormone therapy, this group recovered with regard to sexual performance, and showed itself to be identical to the group of patients that had not undergone hormone therapy.-------------------RESUMÉ:Objectives 1. Évaluer la morbilité urinaire et sexuelle après la realisation la curiethérapie de la prostate avec implant de I125. 2. Évaluer l’ influence de la thérapie hormonale néoadjuvante et adjuvante en ce qui concerne la morbilité urinaire et sexuelle après la réalisation de la curiethérapie (I125). 3. Évaluer l’influence de l’association de la radiothérapie externe dans la morbilité urinaire et sexuelle après la réalisation de la curiethérapie (I125). 4. Évaluer la morbilité urinaire des malades avec des contre indications relatives (prostates volumineuses, IPSS élevé). Matériel et méthodologie De Septembre 2000 à Décembre 2004, on a recruté 204 patients ayant pour diagnostique un carcinome de la prostate localisé (T1 et T2) ou localement avancé (T3) et dont l’expectative de vie était de plus de 10 ans. Ils ont été soumis au traitement de la curiethérapie avec l’implantation transpérinéal de l’iode 125 (I125) en monothérapie ou en traitement combiné avec une thérapie hormonale et/ou radiothérapie externe (traitement trimodale). Il y a eu plusieurs sous-catégories de patients, et cela dépend de quelques caractéristiques normalement considérées comme des facteurs à risque en ce qui concerne la morbilité du traitement de la curiethérapie de la prostate, et l’objective étant d’analyser son influence sur la morbilité urinaire et sexuelle. Groupe 1: Curiethérapie en traitement unique (MONO) par rapport à la curiethérapie associée au traitement externe (BCOMB). Groupe 2: Prostates volumineuses (>50ml) par rapport au prostates qui ne sont pas volumineuses (<50ml). Groupe 3: Curiethérapie associée au traitement hormonale (HORM) par rapport à la curiethérapie sans traitement hormonale (NHORM). Groupe 4: IPSS élevé par rapport au IPSS diminué. Nous avons évalué l’evolution du IPSS, Qualité de vie, le taux de RTU-P et la retention de l’urine après l’implant, BSFI pendant toute la période du traitement. Résultats Groupe 1: Pour le groupe MONO l’IPSS a commençé avec un taux de 7.1, et les patients ont souffert d’un empirement allant jusqu’à 16.1 et 15.9 pendant le premier et le troisième mois. 12 mois après l’IPSS diminua jusqu’à 10.1 À 18 mois le taux fût de 7.3 et à 24 mois il diminua encore jusqu’à atteindre 5.8. Le groupe BCOMB commença avec un taux d’IPSS de 9.4. Ils souffrirent un empirement légér et peu accentué jusqu’aux 6 premiers mois (IPSS de 14). L’évolution de l’IPSS était fluctuante allant de 5.9 à 12 mois et 9.5 à 18 mois. À 24 mois, l’IPSS était de 6.7. Le taux de retention de l’urine (6.4% et 0%) et de la RTU-P (2.0% et 0%) étaient simmilaires dans les groupes MONO et BCOMB respectivement (p=0.375 et p=1). L’ évolution de la qualité des érections fût semblable dans les 2 groupes excepté le groupe MONO qui présenta une valeure de 6 à 6 mois et le groupe BCOMB qui présenta une valeure de 3.7 (p=0.029). Le pourcentage des malades sexuellement puissants a été significativement inférieur pendant les 6 premiers mois depuis la curiethérapie pour le groupe BCOMB si on le compare au groupe MONO: 36%–74%; 33%–73%; 33%–75%. Après cette période, les groupes eûrent des résultats homogénes. Groupe 2: L’ IPSS a évolué dans les prostates <50ml et >50ml de 7–9 jusqu’à 15-19 pendant le premier mois et jusqu’à 15-18 au 3ème mois. C’est seulement pendant le premier mois que les différences de l’IPSS ont été significatives (p=0.061). Après le 3ème mois les deux groupes ont eu des résultats semblables: IPSS 8 et 12 à 12.º mois et 5.7 et 6 à 24.º mois. Le taux de retention de l’urine et de la RTU-P ont été simmilaires (p=0.054 e p=0.286). Groupe 3: L’evolution de l’ IPSS, les taux de retention de l’urine et de la RTU-P pourraient se surposer pour les deux groupes. L’évolution de la libido, des érections, le pourcentage des malades sexuellements puissants, l’incommodité et la satisfaction ont été toujours significativement infériures dans le groupe HORM par rapport au groupe NHORM dès le premier mois (valeurs de p <0.0001; <0.0001; < 0.0001; 0.009 et 0.002 respectivement) Groupe 4: L’évolution de l’ IPSS pour les malades ayant un IPSS élevé fût ainsi: 22.17(0M); 19.5(1M); 20.5(3M); 15.3(6M); 15.7(12M); 11(18M); 8(24M)L’évolution de l’ IPSS pour les malades ayant un IPSS diminué fût ainsi:5.9(0M); 15.3(1M); 14.9(3M); 12.2(6M); 8.9(12M); 7.2(18M), 5.5(24M) Le taux de RTU-P (2.8% e 0%) et de retention de l’urine (5.1% et 5.9%) ont été semblables dans les 2 groupes de malades (p=1). Conclusions 1. La radiothérapie interstitielle de la prostate avec implant transpérinéal de l’iode 125 est fréquamment acompagnée d’une morbilité urinaire transitoire et d’intensité modérée. La morbilité consiste d’une symptomatologie de l’apparéil urinaire inférieure qui, dans la plupart des malades, empire gravement du premier au troisième mois. La situation s’améliore légèrement jusqu’au 6ème mois, l’amélioration étant plus accentuée à partir de là. Autour du 12ème jusqu’au 18ème mois, la majorité des malades présente une symptomatologie urinaire qui se ressemble beaucoup à celle qu’ils avaient avant le traitement. Après le 18ème mois l’amélioration de la symptomatologie urinaire est constante par rapport à celle qu’ils présentaient avant l’implant. Le taux de retention de l’urine et de RTU-P après l’implant de la curiethérapie sont très basses, au dessus de 10%. 2. L’association de la curiethérapie de la prostate avec la radiothérapie externe adjuvante a une influence sur l’évolution de la symptomatologie urinaire: l’apparition des symptômes est plus lente, prenant jusqu’à 6 mois pour atteindre son niveau maximum, qui à son tour, a une intensité moins accentuée que lorsque la curiethérapie est utilisée en monothérapie. 3. Le volume de la prostate supérieure à 50 ml n’a pas d’influence sur la morbilité urinaire. 4. La thérapie hormonale, néoadjuvante et adjuvante, n’a pas d’influence sur la symptomatologie urinaire. 5. Les malades ayant une symptomatologie urinaire préalable et très accentuée ne souffrent pas d’empirement de leur situation. Au contraire, ils présentent une amélioration des symptômes urinaires à partir du premier mois et ceci se maintient tout au long des 24 mois que dure le traitement, ayant à la fin de cette période une symptomatologie urinaire légère et beaucoup plus basse que celle qu’ils présentaient avant l’implant. Le taux de retention de l’urine et de la RTU-P après la curiethérapie est simmilaire à celui que les malades qui n’ont pas de symptômes présentent avant l’implant. 6. La vie sexuelle est préservée dans plus du 70% des cas à la fin de la période de traitement (24 mois). Entretemps, immédiatement après le premier mois d’étude, on note une légère diminution de la qualité des érections qui se maintient sans amélioration ou empirement tout au long du traitement. Le traitement à base d’hormones affecte tous les paramètres de la vie sexuelle, mais de façon temporaire. Après la suspension de la thérapie hormonale ce groupe de malades récupère l’activité sexuelle et se présente de façon égale au groupe de malades qui n’ont pas été soumis à ce traitement.

Influência do ciclo menstrual na fracção exalada de óxido nítrico

RESUMO:A determinação da fracção exalada de óxido nítrico (FENO) é amplamente utilizada como um biomarcador da inflamação eosinofílica das vias aéreas. Alguns estudos sugerem que a produção de óxido nítrico (NO) é influenciada pelas variações cíclicas hormonais na mulher,porém os dados não são consensuais. Deste modo, o objectivo do nosso estudo foi avaliar como varia a FENO ao longo do ciclo menstrual. Com esta finalidade, avaliamos um grupo de 20 voluntárias, em idade fértil, com ciclo menstrual regular, não fumadoras, que não utilizavam contraceptivos hormonais, nem suplementos alimentares e/ou medicamentosos e que não se encontravam grávidas, nem a amamentar. Todas referiram não ter conhecimento de qualquer patologia que afecte a FENO. A existência de atopia foi controlada através de testes cutâneos por prick, tendo-se excluído as participantes que apresentaram testes positivos. Realizamos quatro visitas de estudo, com base na periodicidade do ciclo de cada participante, nas quais, efectuamos a determinação da FENO, a quantificação dos níveis plasmáticos de óxido nítrico e nitratos (NO/NO3 -) e o doseamento hormonal de 17 -estradiol e progesterona. As avaliações realizaram-se no período da manhã, em jejum absoluto, tendo respeitado uma dieta pobre em nitratos no dia anterior e abstido da prática de exercício vigoroso uma hora antes da avaliação. Com este trabalho, verificamos um aumento significativo da FENO na fase secretora (17.97 ppb ± 5.8) comparativamente com a fase menstrual e proliferativa (16.48 ppb ± 3.6 e 15.95 ppb ±2.8, respectivamente). Não observamos variações significativas dos níveis plasmáticos de NO/NO3 - ao longo do ciclo. Constatamos uma correlação positiva entre a FENO e os níveis plasmáticos de NO/NO3 - durante a ovulação e verificamos que, para a nossa amostra, os níveis hormonais de estradiol e progesterona não são preditores do valor da FENO, nem dos níveis plasmáticos de NO/NO3-. Os resultados deste trabalho mostram uma variação da FENO ao longo do ciclo, ainda assim, mantendo-se os seus valores dentro do intervalo de referência, reforçando a fiabilidade deste biomarcador.--ABSTRACT:The determination of fractional exhaled nitric oxide (FENO) is widely used as a biomarker of eosinophilic airway inflammation. Some studies suggest that nitric oxide (NO) is influenced by cyclical hormonal changes in women, but those are not consensual. The aim of our study was to assess how FENO varies throughout the menstrual cycle. With this purpose, we studied a group of 20 volunteers within childbearing age, with regular menstrual cycle, non-smokers, who were not taking any medications including hormonal contraception and food supplements and who were not pregnant or breast-feeding. All participants reported not being aware of any condition that could affect the FENO. The presence of atopy was controlled by a skin prick test, having been excluded participants with positive test. We conducted four study visits, based on the periodicity of the cycle of each participant. In each visit, we made the determination of the FENO, the quantification of plasmatic levels of nitric oxide and nitrates (NO/NO3 -) and the blood levels of hormone estradiol-17 and progesterone. The evaluations occurred at morning, after overnight fasting. The participants were request to follow a low-nitrate diet in the previous day and refrained from vigorous exercise, for at least one hour before the visit We found a significant increase of FENO on secretory phase (17.97 ppb ± 5.8) compared with the menstrual and proliferative phase (16.48 ppb ± 3.6 and 15.95 ppb ± 2.8, espectively). No significant variations were found throughout the menstrual cycle in plasmatic levels of NO/NO3 -. We found a positive correlation between FENO and plasmatic levels of NO/NO3 - during ovulation. Finally, in our sample, the levels of oestradiol and progesterone are not predictors of FENO value nor of plasmatic levels of NO/NO3-. This study shows a variation of FENO over the menstrual cycle, nevertheless, the values remain within the reference range, reinforcing the reliability of this biomarker.

Magnetic Resonance Imaging and Gynecological Devices

Background: Performing magnetic resonance imaging (MRI) on women with gynecological devices is a completely accepted practice. The goal of our review is to assess how safe it is to perform MRI on women using contraceptive implants or devices. Study Design: Literature review, searching in PubMed-Medline/Ovid for the following keywords: magnetic resonance imaging, intrauterine devices, Implanon® and Essure®. Results: Though plastic devices do not represent a contraindication to the use of the technique, those including metallic components have been submitted to several tests, after which they were classified as MR Conditional (devices presenting no risks in MR-specific environments) by the Food and Drug Administration. Thus, the use of MRI can be safely advised to women with this type of device as long as the magnetic resonance equipment is ≤3.0 T. Conclusions: Presently, there is no scientific evidence that contraindicates performing MRI on women with any kind of gynecological device. Therefore, this procedure is safe as long as it is performed under previously tested conditions.

Trombofilias e Contracepção

Thrombophilias, whether inherited or acquired, are a topic of increased interest in women’s health. Factors that enhance thrombus formation in the presence of thrombophilia include oral contraception, hormone replacement therapy, pregnancy and the puerperium. The risk of venous thomboembolism with hormonal contraceptive use is greater in women with underlying thrombophilias, and thrombosis usually occurs earlier than in women without defined thrombophilias. The degree of increased risk varies according to the underlying thrombophilic defect, the largest bulk of evidence referring to women with Factor V Leiden or prothrombin gene mutation. However, most instances of thrombosis occur due to a combination of inherited, acquired and environmental factors. Before starting oral contraception it is important to screen patients to identify those at increased risk of thrombosis.

In Situ Breakage of Implanon® - Two Cases of a Rare Occurrence

BACKGROUND: In situ breakage of Implanon® is a rare occurrence with unknown clinical significance. Authors report two different cases of broken Implanon® of women attended at our Family Planning Clinic. DISCUSSION: In situ implants may spontaneously and asymptomatically break, although some uncertainty relies on whether that situation has a real impact on the contraceptive effectiveness or on bleeding patterns. Even more, it can be argued if, as a result of an occurrence of that nature, the implant shall or shall not be removed before the envisaged 3-year period of effectiveness. CONCLUSION: Currently, the clinical significance of implant breakage remains unknown. The decision to remove a broken or bent implant should be based on clinical judgements considering patients' wishes.

Saúde Sexual e Reprodutiva das Adolescentes - a Nossa Realidade

Overview and Aims: Several behavioral and biological factors can make adolescents particularly vulnerable to unwanted pregnancies and sexually transmitted diseases. The aim of this study was to evaluate sexual behavior and contraceptive use patterns of a population of adolescents. Study Design: Retrospective study. Population: 163 female adolescents attending an Adolescence Unit for the first time, during 2010. Methods: Analysis of clinical charts and assessment of demographic data, smoking and drinking habits, drug use, gynecologic and obstetric history, sexual behavior and contraceptive use. Results: The mean age was 16.04 years (±1.32). 71.7% were students (of these, 70% had failed one or more years and were behind in their studies), 2.5% were working and 23.9% were neither studying or working. 95.1% had already had sexual intercourse and the mean age of first coitus was 14.53 years (±1.24). There was a history of at least one previous pregnancy in 77.3% of the cases. Before the first appointment at the AU, the contraceptive methods used were: the pill (33.2%, but 41.3% of these reported inconsistent use), and the condom (23.9%, with inconsistent use in 28.3% of these cases). 19.6% did not use any contraceptive method.. After counseling at the AU, 54% of the teenagers chose the contraceptive implant and 35% preferred the pill. Adolescents who had already been pregnant preferred a long acting method (namely, the contraceptive implant)in 61.9% of cases; those who had never been pregnant decided to use an oral contraceptive in 67.6% of cases (p<0.001). Conclusions: After counseling the number of teenagers using contraception increased. In this population there were a high number of adolescents with a previous pregnancy. This factor seems to have influenced the choice of the contraceptive method, with most of these adolescents choosing a long-acting method.

Contraceptive Choices Pre and Post Pregnancy in Adolescence

STUDY OBJECTIVE: The main aim of this study is to evaluate the impact of adolescent pregnancy in the future contraceptive choices. A secondary aim is to verify whether these choices differ from those made after an abortion. DESIGN: Retrospective study. SETTING:Adolescent Unit of a tertiary care center. PARTICIPANTS:212 pregnant teenagers. INTERVENTIONS: Medical records review. MAIN OUTCOME MEASURES:Intended pregnancy rate and contraceptive methods used before and after pregnancy. For contraceptive choices after pregnancy we considered: Group 1 - teenagers who continued their pregnancy to delivery (n = 106) and Group 2 - the same number of adolescents who chose to terminate their pregnancy. RESULTS: The intended pregnancy rate was 14.2%. Prior to a pregnancy continued to delivery, the most widely used contraceptive method was the male condom (50.9%), followed by oral combined contraceptives (28.3%); 18.9% of adolescents were not using any contraceptive method. After pregnancy, contraceptive implant was chosen by 70.8% of subjects (P < .001) and the oral combined contraceptives remained the second most frequent option (17.9%, P = .058). Comparing these results with Group 2, we found that the outcome of the pregnancy was the main factor in the choices that were made. Thus, after a pregnancy continued to delivery, adolescents prefer the use of LARC [78.4% vs 40.5%, OR: 5,958 - 95% (2.914-12.181), P < .001)], especially contraceptive implants [70.8% vs 38.7%, OR: 4.371 - 95% (2.224-8.591), P < .001], to oral combined contraceptives [17.9% vs 57.5%, OR: 0.118 - 95% CI (0.054-0.258), P < .001]. CONCLUSION:Adolescent pregnancy and its outcome constitute a factor of change in future contraceptive choice.
