Associação da catastrofização da dor com a incidência e a intensidade da dor perineal aguda e persistente após parto normal: estudo longitudinal tipo coorte

BACKGROUND AND OBJECTIVES: Vaginal birth delivery may result in acute and persistent perineal pain postpartum. This study evaluated the association between catastrophizing, a phenomenon of poor psychological adjustment to pain leading the individual to magnify the painful experience making it more intense, and the incidence and severity of perineal pain and its relationship to perineal trauma. METHOD: Cohort study conducted with pregnant women in labor. We used the pain catastrophizing scale during hospitalization and assessed the degree of perineal lesion and pain severity in the first 24 hours and after 8 weeks of delivery using a numerical pain scale. RESULTS: We evaluated 55 women, with acute pain reported by 69.1%, moderate/severe pain by 36.3%, and persistent pain by 14.5%. Catastrophizing mean score was 2.15 ± 1.24. Catastrophizing patients showed a 2.90 relative risk (RR) for perineal pain (95% CI: 1.08-7.75) and RR: 1.31 for developing persistent perineal pain (95% CI: 1.05-1.64). They also showed a RR: 2.2 for developing acute and severe perineal pain (95% CI: 1.11-4.33). CONCLUSIONS: The incidence of acute and persistent perineal pain after vaginal delivery is high. Catastrophizing pregnant women are at increased risk for developing acute and persistent perineal pain, as well as severe pain. Perineal trauma increased the risk of persistent perineal pain.

Prevalence of and risk factors for bacterial vaginosis among women of reproductive age attending cervical screening in southeastern Brazil

To determine the prevalence of and risk factors for bacterial vaginosis. A cross-sectional study of women aged 14-54 years attending 18 primary healthcare units in Botucatu, Brazil, for cervical screening was undertaken between September 1, 2012, and January 31, 2013. Data on sociodemographics, sexual behavior, and medical history were obtained by interview. Vaginal swabs were taken to classify the vaginal flora according to the Nugent scoring system. Candida sp. hyphae and infection by Trichomonas vaginalis were also evaluated by microscopy and culture, respectively. Stepwise logistic regression analysis was performed to identify risk factors independently associated with bacterial vaginosis. Among 1519 women included in analyses, 457 (30.1%) had bacterial vaginosis. Variables independently associated with bacterial vaginosis were a single marital status (OR 1.4; 95%CI 1.1-1.8), partner infidelity (OR 1.5; 95%CI 1.2-1.9), abnormal discharge in the previous year (OR 1.5; 95%CI 1.2-2.0), and concurrent trichomoniasis (OR 4.1; 95%CI 1.5-11.5). Current use of hormonal contraception (OR 0.7; 95%CI 0.5-0.9), luteal phase of menstrual cycle (OR 0.8; 95%CI 0.6-0.9), higher income (OR 0.8; 95%CI 0.6-0.9), and vaginal candidiasis (OR 0.5; 95%CI 0.3-0.9) all had protective effects. The prevalence of bacterial vaginosis in the study population is high. The epidemiological data provide evidence of the sexual transmissibility of bacterial vaginosis.

Leishmania sp. amastigotes identification in canine transmissible venereal tumor

Leishmaniasis is a vector-borne disease with Leishmania chagasi being the etiological agent of canine visceral leishmaniasis in South America. Canine venereal tumor is a transplantable round cell tumor of histiocytic origin which is mostly observed in sexually active male and female intact dogs. It has been shown that Leishmania amastigotes have higher tropism for the canine male genital tract tissues and venereal leishmaniasis transmission has been documented in dogs but, to date, a canine venereal tumor-dependent transmission route has not been fully demonstrated. In this report, a 10-year-old, mixed breed, intact female dog presented a vaginal venereal transmissible tumor but no other clinical abnormalities otherwise. Unexpectedly, tumor tissue imprint smears examination revealed Leishmania sp. amastigotes within infiltrating macrophages. In addition to the cytological direct identification, the protozoan was confirmed within the neoplastic tissue by means of immunohistochemistry and polymerase chain reaction. This report illustrates an asymptomatic Leishmania sp. infection that may have started on or from the canine venereal tumor tissue, the latter option further supporting previous evidence of such an alternative vector-independent route of transmission for canine visceral leishmaniasis in areas where these diseases coexist.

Reproductive physiology, and physical and sexual development of female offspring born to diabetic dams

Objectives: The objective of this study was to evaluate physical and sexual development and reproductive physiology in female rat offspring that developed in hyperglycemia conditions in utero and during lactation. Materials and methods: Maternal diabetes was induced in female rats by a single IV injection of streptozotocin before mating. Female offspring development was evaluated by means of the following parameters: physical development; age of vaginal opening and first estrus; weight and histological evaluation of uterus and ovaries; duration of the estrous cycle, sexual behavior, and fertility after natural mating. Results: In the female offspring, maternal diabetes caused delays in initial physical development; diminution in ovary weight and number of follicles; and inferior reproductive performance compared with the control group. Conclusions: The exposure to hyperglycemia in uterus and during lactation caused delays in physical and sexual development, and affected the reproductive physiology of female rats negatively.

Biopsias luteais em vacas Nelore

The present study describes a technique to obtain consecutive luteal samples by colpotomy. The animals received an epidural anesthesia and local anesthesia (vaginal vault) and after ten minutes the vaginal vault was incised with a scalpel blade and tissue was dissected to provide access to the pelvic cavity and to retract the ovary into the vagina. Then, a luteal biopsy was performed with a Yomann biopsy nipper. Signs indicative of pain and stress during the vaginal vault incision, traction of ovary or luteal biopsy were observed only in two collections. However, these signs were observed in ten collections during dissection of the vaginal wall and peritoneum. The occurrence of ataxia was observed in 26 collections and it was usually related to a longer duration of the procedure. Ataxia could be divided in light (15/26), moderate (6/26) and severe (5/26). The occurrence of ovarian adhesions ipsilateral to the incision was evaluated only in the initial four collections. Adhesions were present in 16 collections. The protocol described above provided a safe and efficient method to acquire luteal samples. The low incidence of adhesions allows the consecutive use of females without any interference in subsequent ovulations and collections.

CHALLENGES TO THE ORGANIZATION OF A CERVICAL CANCER SCREENING PROGRAM IN MANAUS-AM

The purpose was to investigate sociodemographic characteristics of women who underwent a Pap smear test in Manaus, Amazonas, Brazil, and identify the reasons why the women had the test. This exploratory study was performed with 281 women who had taken the Pap smear test within the last five years in Manaus. Most participants were between 18 to 34 years old (54%), had 5 to 11 years of education (54.4%), had a monthly income of less than three minimum wage salaries (84.3%) and were in a stable relationship (72.2%), with an onset of sexual activity between the ages of 15 to 19 years (69.4%). The reasons for their taking the Pap test were personal choice (66.2%), recommendation by a physician (23.5%) and gynecological symptoms (10.3%). Women who received information about the Pap test from health professionals had a greater chance of being tested within the last three years (p=0.008). Women choosing to have the exam (personal choice) are prevalent, and the opportunistic service is provided to younger women, thus not reaching the group at greater risk for cancer. It is necessary to implement active recruitment strategies to reach women in situations of socioeconomic disadvantage.

A clinical and hemogasometric survey of neonatal lambs

In order to provide adequate medical assistance to neonates, the extent of vitality impairment has to be investigated through complementary exams, as well as clinical assessment. This investigation aimed to identify the physiological changes that occur during neonatal adaptation and to develop a clinical approach that can be performed during the first hour of life in neonatal lambs born through vaginal eutocic labor. The neonatal vitality of 14 Santa Ines lambs was verified using the Apgar system and rectal temperature at birth and after 5 and 60 min after birth. From the total number of neonates, 7 lambs were randomly selected for blood gas analysis and glucose immediately at birth and 1 h after birth. The lambs had hypoglycemia immediately after birth, as well as acidosis due to metabolic and respiratory causes. Given their hypoxemia at birth, lambs immediately exhibit tachycardia and tachypnea. However, neonatal lambs reached Apgar score superior than 7 after 5 min of birth. Ovine neonates are relatively mature at birth, with adequate thermoregulation and active mechanisms to compensate for physiological acid-base imbalances. In conclusion, a systematic clinical examination of newborn sheep should include the implementation of the Apgar score coupled with the confirmation of any acid-base imbalances. Further research should evaluate neonatal adaptation to this critical period over a longer period of time. (C) 2012 Elsevier B.V. All rights reserved.
