Efficacy of the motile sperm organelle morphology examination (MSOME) in predicting pregnancy after intrauterine insemination

Background: Although the motile sperm organelle morphology examination (MSOME) was developed merely as a selection criterion, its application as a method for classifying sperm morphology may represent an improvement in the evaluation of semen quality. The aim of this study was to determine the prognostic value of normal sperm morphology using MSOME with regard to clinical pregnancy (CP) after intrauterine insemination (IUI).Methods: A total of 156 IUI cycles that were performed in 111 couples were prospectively analysed. Each subject received 75 IU of recombinant FSH every second day from the third day of the cycle. Beginning on the 10th day of the cycle, follicular development was monitored by vaginal ultrasound. When one or two follicles measuring at least 17 mm were observed, recombinant hCG was administered, and IUI was performed 12-14 h and 36-40 h after hCG treatment. Prior to the IUI procedure, sperm samples were analysed by MSOME at 8400x magnification using an inverted microscope that was equipped with DIC/Nomarski differential interference contrast optics. A minimum of 200 motile spermatozoa per semen sample were evaluated, and the percentage of normal spermatozoa in each sample was determined.Results: Pregnancy occurred in 34 IUI cycles (CP rate per cycle: 21.8%, per patient: 30.6%). Based on the MSOME criteria, a significantly higher percentage of normal spermatozoa was found in the group of men in which the IUI cycles resulted in pregnancy (2.6+/-3.1%) compared to the group that did not achieve pregnancy (1.2+/-1.7%; P = 0.019). Logistic regression showed that the percentage of normal cells in the MSOME was a determining factor for the likelihood of clinical pregnancy (OR: 1.28; 95% CI: 1.08 to 1.51; P = 0.003). The ROC curve revealed an area under the curve of 0.63 and an optimum cut-off point of 2% of normal sperm morphology. At this cut-off threshold, using the percentage of normal sperm morphology by MSOME to predict pregnancy was 50% sensitive with a 40% positive predictive value and 79% specificity with an 85% negative predictive value. The efficacy of using the percentage of normal sperm morphology by MSOME in predicting pregnancy was 65%.Conclusions: The present findings support the use of high-magnification microscopy both for selecting spermatozoa and as a routine method for analysing semen before performing IUI.

Malformação arteriovenosa uterina após doença trofoblástica gestacional

OBJETIVO: investigar a presença e resultados de malformações vasculares uterinas (MAVU) após doença trofoblástica gestacional (DTG). MÉTODOS: estudo retrospectivo com inclusão de casos diagnosticados entre 1987 e 2004; 2764 pacientes após DTG foram acompanhadas anualmente com ultra-sonografia transvaginal e Doppler colorido no Centro de Neoplasia Trofoblástica Gestacional da Santa Casa da Misericórdia (Rio de Janeiro, RJ, Brasil). Sete pacientes tiveram diagnóstico final de MAVU baseado em análise ultra-sonográfica - índice de pulsatilidade (IP), índice de resistência (IR) e velocidade sistólica máxima (VSM) - e achados de imagens de ressonância nuclear magnética (RNM). Dosagens negativas de beta-hCG foram decisivas para estabelecer o diagnóstico diferencial com DTG recidivante. RESULTADOS: a incidência de MAVU após DTG foi 0,2% (7/2764). Achados ultra-sonográficos de MAVU: IP médio de 0,44±0,058 (extremos: 0,38-0,52); IR médio de 0,36±0,072 (extremos: 0,29-0,50); VSM média de 64,6±23,99 cm/s (extremos: 37-96). A imagem de RNM revelou útero aumentado, miométrio heterogêneo, espaços vasculares tortuosos e vasos parametriais com ectasia. A apresentação clínica mais comum foi hemorragia transvaginal, presente em 52,7% (4/7) dos casos. Tratamento farmacológico com 150 mg de acetato de medroxiprogesterona foi empregado para controlar a hemorragia, após a estabilização hemodinâmica. Permanecem as pacientes em seguimento, assintomáticas até hoje. Duas pacientes engravidaram com MAVU, com gestações e partos exitosos. CONCLUSÃO: presente sangramento transvaginal em pacientes com beta-hCG negativo e história de DTG, deve-se considerar a possibilidade de MAVU e solicitar avaliação ultra-sonográfica com dopplervelocimetria. O tratamento conservador é a melhor opção na maioria dos casos de MAVU pós-DTG.

Effect of indomethacin on the pregnant rat

O objetivo deste trabalho foi avaliar a performance reprodutiva, estudo morfológico do fígado e característicapost mortem de ratas Wistar prenhes tratadas com indometacina, um inibidor geral de COX. Indometacina foi administrada oralmente, nas doses de 0 (controle), 0,32, 1,68 e 8,40 mg/kg/dia (n=10/grupo), nos dias 3 e 4 de prenhez (dia 0 = primeiro dia de prenhez = esperma positivo). Os animais foram eutanasiados sob anestesia no 11º dia de prenhez, e foram realizadas necropsia e cultura de microorganismos. Os resultados mostraram que as doses de 0,32 e 1,68 mg/kg de peso corpóreo (dose terapêutica para humanos) de indometacina não causaram efeitos embriotóxicos ou letais. A maior dose (8,40 mg/kg) de indometacina prejudicou o processo de implantação e, portanto, interferiu no desenvolvimento fetal. A peritonite foi detectada na necropsia e nos estudos bacteriológicos dos animais tratados com 8,4 mg/kg e considerada a causa-morte destes animais. Portanto, este estudo analisou um agente farmacológico na prenhez de roedores e evidenciou que a indometacina apresentou efeitos embriotóxicos e letais na maior dose empregada, mas foi segura na dose terapêutica usada pelo homem.

Efeitos da isoflavona sobre os sintomas climatéricos e o perfil lipídico na mulher em menopausa

OBJETIVO: avaliar os efeitos da isoflavona, do gérmen da soja, sobre os sintomas climatéricos e o perfil lipídico na mulher em menopausa. MÉTODOS: foi conduzido estudo prospectivo, com 50 mulheres em menopausa, divididas em: G1, usuárias de isoflavona (60 mg/dia) (n=25), e G2, placebo (n=25). Os critérios de inclusão foram FSH >40 mUI/mL e presença de fogachos. Foram excluídas as vegetarianas, fumantes, asiáticas, portadoras de doenças gastrointestinais e usuárias de terapia de reposição hormonal. No seguimento, de seis meses, foram obtidos o índice menopausal de Kupperman (IMK), o perfil hormonal e o lipídico. Na análise estatística, empregaram-se ANOVA, o teste t pareado e as provas não paramétricas de Wilcoxon e Mann-Whitney. RESULTADOS: os valores medianos do IMK, inicialmente iguais entre os grupos (IMK = 20), reduziram-se nas usuárias de isoflavona aos 2 e 4 meses (IMK = 14 e 9, respectivamente) e no grupo controle, apenas aos 2 meses (IMK = 15) (p<0,01). Ao final do estudo, a isoflavona foi superior ao placebo na redução dos fogachos (44% versus 12%, respectivamente). Aos seis meses, verificou-se que os valores médios de estradiol foram superiores no G1 quando comparados ao G2 (18,0 ± 6,7 versus 12,3 ± 3,8 ng/dL) (p<0,05), sem alterações no FSH e LH. Entre as usuárias de isoflavona, houve redução de 11,8% no LDL (de 151,5 ± 39,2 para 133,6 ± 26,4 mg/dL) e elevação de 27,3% no HDL (de 44,0 ± 11,3 para 56,0 ± 11,9 mg/dL) (p<0,05). CONCLUSÕES: a isoflavona, do gérmen da soja, induziu efeitos favoráveis sobre os sintomas climatéricos e o perfil lipídico, revelando-se opção interessante como terapêutica alternativa para mulheres em menopausa.

Correlation of Atopobium vaginae Amount With Bacterial Vaginosis Markers

Objective. The purpose of this study was to test the correlation of the amount of Atopobium vaginae with the most commonly used markers for bacterial vaginosis (BV).Materials and Methods. We enrolled 103 nonpregnant and premenopausal women that were positive for BV by Amsel criteria and with a Nugent score higher than 3. All women were negative for yeast, Chlamydia trachomatis, Trichomonas vaginalis, and Neisseria gonorrhoeae. A. vaginae concentration was determined by quantitative polymerase chain reaction from samples of vaginal rinsings with 2 mL of sterile saline.Results. There was no difference in the median values of A. vaginae concentration when comparing samples with presence or absence of each individual Amsel criterion. In the case of a higher pH cutoff value of 4.9, greater amounts of this microorganism (p = .02) were found. In addition, correlation tests showed that A. vaginae concentration is positively correlated with pH (p < .001) and with Nugent scores (p = .003).Conclusions. The quantification of A. vaginae is useful for identification of the most severe cases of BV.

Análise das condições de saúde e de vida da população urbana de Botucatu, SP (Brasil): III - Conhecimentos e opiniões dos profissionais de saúde a respeito de sintomas de doenças, 1984

Foram estudados os conhecimentos e opiniões dos profissionais de saúde do Município de Botucatu, SP (Brasil), acerca da freqüência e gravidade de treze sintomas e sinais de doenças, visando à comparação com as opiniões emitidas pela população urbana do Município. Foram entrevistados 435 profissionais de saúde ativos (médicos, enfermeiros, auxiliares e atendentes de enfermagem e outros), a maioria do sexo feminino, com idade de 25 a 44 anos. A categoria de atendentes foi a mais numerosa. de modo geral, os cinco últimos sintomas da relação constante do formulário - sangue no escarro, sangramento vaginal, caroço no seio, acessos e sangue na urina, foram considerados menos freqüentes e mais graves, comparativamente aos oito primeiros: falta de ar, febre, fraqueza, dor nas costas, dor no peito, dor de cabeça, tosse e diarréia. Dentre as categorias, os médicos diferenciaram-se atribuindo, com menor freqüência, escores altos para a freqüência e gravidade. Os clínicos valorizaram mais do que os cirurgiões, esses dois fatores, para quase todos os sintomas. O cotejo com a opinião dos leigos entrevistados revelou semelhanças nas tendências, embora tenha havido, por parte destes, maior valorização da freqüência e gravidade.

Effect of intravaginal electrical stimulation on pelvic floor muscle strength

The aim of this study was to evaluate the effect of intravaginal electrical stimulation (IES) on pelvic floor muscle (PFM) strength in patients with mixed urinary incontinence (MUI). Between January 2001 and February 2002, 40 MUI women (mean age: 48 years) were studied. Urge incontinence was the predominant symptom; 92.5% also presented mild stress urinary incontinence (SUI). Selection criteria were clinical history and urodynamics. Pre-treatment urodynamic study showed no statistical differences between the groups. Ten percent of the women in each group had involuntary detrusor contractions. Patients were randomly distributed, in a double-blind study, into two groups. Group G 1 (n=20), effective IES, and group G2 (n=20), sham IES, with follow-up at 1 month. The following parameters were studied: (1) clinical questionnaire, (2) examiner's evaluation of perineal muscle strength, (3) objective evaluation of perineal muscle by perineometry, (4) vaginal weight test, and (5) urodynamic study. The IES protocol consisted of three 20-min sessions per week over a 7-week period using a Dualpex Uro 996 at 4 Hz. There was no statistically significant difference in the demographic data of both groups. The number of micturitions per 24 h after treatment was reduced significantly in both groups. Urge incontinence, present in all patients before treatment, was reduced to 15% in G1 and 31.5% in G2 post-treatment. The subjective evaluation of PFM strength demonstrated a significant improvement in G1. Objective evaluation of PFM force by perineometer showed a significant improvement in maximum peak contraction post-treatment in both groups. In the vaginal weight test, there was a significant increase in average number of cone retentions post-treatment in both groups. With regard to satisfaction level, after treatment, 80% of the patients in G1 and 65% of the patients in G2 were satisfied. There was no statistically significant difference between the groups. There was a significant improvement in PFM strength from both effective and sham electrostimulation, questioning the effectiveness of electrostimulation as a monotherapy in treating MUI.

Pelvic floor muscle evaluation in incontinent patients

The aim of this study was to assess pelvic floor muscle (PFM) strength and perception and its correlation with stress urinary incontinence (SUI). One hundred and one women were divided into two groups according to the presence (G1=51 patients) or absence (G2=50 patients) of SUI. Subjective [urine stream interruption test (UST), visual survey of perineal contraction and transvaginal digital palpation to assess pelvic muscle contraction] and objective evaluations of pelvic floor muscles in all patients were performed (vaginal manometry). During the UST, 25.5% of G1 patients and 80% of G2 patients were able to interrupt the urine stream (p<0.05). Digital evaluation of pelvic muscular contraction showed higher strength in G2 than in G1 patients (p<0.0001). Perineometer evaluation of PFM strength was significantly higher in the continent group (p<0.001). Pelvic floor muscle weakness in incontinent patients demonstrates the importance of functional and objective evaluation of this group of muscles.

A comparative analisys of pelvic floor muscle strength in women with stress and urge urinary incontinence

Aims: To assess pelvic floor muscle (PFM) strength in women with stress urinary incontinence (SUI) and urge urinary incontinence (UUI).Materials and Methods: 51 women were prospectively divided into two groups, according to the symptoms as SUI (G1 = 22) or UUI (G2 = 29). Demographic data, such as number of pads/ 24 hours, number of micturations/ 24 hours and nocturia, delay time of urgent void (i.e., the time period for which an urgent void could be voluntarily postponed), number of parity and vaginal deliveries were obtained using a clinical questionnaire. Objective urine loss was evaluated by 60-min. Pad Test, subjective urine stream interruption test (UST) and visual survey of perineal contraction. Objective evaluations of PFM were performed in all patients (vaginal manometry).Results: Median of age, mean number of pads/ 24 hours, nocturia and warning time were significantly higher in UUI comparing to SUI group. During UST, 45.45% in G1 and 3.44%, in G2, were able to interrupt the urine stream (p < 0.001). The 60-min. Pad Test was significantly higher in G2 compared to G1 women (2.7 +/- 2.4 vs 1.5 +/- 1.9 respectively, p = 0.049). Objective evaluation of PFM strength was significantly higher in the SUI than in the UUI patients. No statistical difference was observed regarding other studied parameters.Conclusion: Pelvic floor muscle weakness was significantly higher in women with UUI when compared to SUI.

Comparison of pelvic floor muscle strength evaluations in nulliparous and primiparous women: a prospective study

OBJECTIVE: This study aimed to compare the pelvic floor muscle strength of nulliparous and primiparous women.METHODS: A total of 100 women were prospectively distributed into two groups: Group 1 (G1) (n = 50) included healthy nulliparous women, and Group 2 (G2) (n = 50) included healthy primiparous women. Pelvic floor muscle strength was subjectively evaluated using transvaginal digital palpation. Pelvic floor muscle strength was objectively assessed using a portable perineometer. All of the parameters were evaluated simultaneously in G1 and were evaluated in G2 during the 20(th) and 36(th) weeks of pregnancy and 45 days after delivery.RESULTS: In G2, 14 women were excluded because they left the study before the follow-up evaluation. The median age was 23 years in G1 and 22 years in G2; there was no significant difference between the groups. The average body mass index was 21.7 kg/m(2) in G1 and 25.0 kg/m(2) in G2; there was a significant difference between the groups (p = 0.0004). In G2, transvaginal digital palpation evaluation showed significant impairments of pelvic floor muscle strength at the 36(th) week of pregnancy (p = 0.0006) and 45 days after vaginal delivery (p = 0.0001) compared to G1. Objective evaluations of pelvic floor muscle strength in G2 revealed a significant decrease 45 days after vaginal delivery compared to nulliparous patients.CONCLUSION: Pregnancy and vaginal delivery may cause weakness of the pelvic floor muscles.

Laparoscopic management of iatrogenic lesions

Purpose: To present our series of patients who underwent laparoscopic correction of iatrogenic lesions and a review of the literature.Patients and Methods: We evaluated 23 patients who underwent laparoscopic correction of iatrogenic lesions. Thirteen patients had open surgery, 6 had an endoscopic procedure, and 4 had a laparoscopic approach as the first surgical procedure. Vesicovaginal fistulas (VVF) developed in seven patients after open abdominal hysterectomies, and 1 patient presented with a VVF after ureterolithotripsy. A urethral cutaneous fistula developed in one patient after a laparoscopic resection of endometriosis nodules, and 1 patient presented with a ureterovaginal fistula after a perineoplasty. Three patients presented with encrusted ureteral stents after ureterolithotripsy. Ureteral stenosis developed in seven patients: three after open abdominal surgery, three after ureteroscopy, and one after pyeloplasty. One patient had a ureteral injury during laparoscopic partial nephrectomy, and two patients had bowel injuries after a tension-free vaginal tape procedure and a laparoscopic radical prostatectomy.Results: All patients underwent laparoscopic correction of the iatrogenic injuries. One patient had an early recurrence of a VVF, and one patient had a recurrence of a ureteral stenosis. There was one conversion to open surgery because of technical difficulties and one major bleeding event that necessitated blood transfusion. A lower limb compartmental syndrome developed in one patient.Conclusion: Despite the small number of patients and different types of surgeries performed, laparoscopic management of iatrogenic lesions seems to be feasible and safe in experienced hands. Its precise role in the management of this stressful condition still needs to be determined.
