OBJECTIVE To report the unusual occurrence of a perineal lipoblastoma presenting as a painless enlarging mass in an infant. CASE PRESENTATION AND INTERVENTION A 7-month-old boy presented with a 6-month history of an asymptomatic progressively enlarging perineal mass. Imaging studies were unable to provide a diagnosis. Complete resection of the mass was achieved and there was no recurrence at ...

We investigated the temporal relationship between abdominal temperature, physical activity, perineal swelling, and urinary progesterone and estradiol concentrations over the menstrual cycle in unrestrained captive baboons. Using a miniature temperature-sensitive data logger surgically implanted in the abdominal cavity and an activity data logger implanted subcutaneously on the trunk, we measure...

This study assessed the relation between perineal body length and the risk of perineal laceration extending into the anal sphincter during vaginal delivery in primigravid patients at an institution with a low utilization of episiotomy. This was a prospective study of primigravid patients in active labor. Primigravid women with singleton pregnancies who were in the first stage of labor at 37 wee...

PURPOSE This study compared the catheter-associated urinary tract infection (CAUTI) rates resulting from the use of four perineal care agents (soap-and-water, skin cleansing foam, 10% povidone-iodine, and normal saline) among patients in intensive care units (ICUs). METHODS This four-group experimental study was done with 97 adult patients who had urinary catheters over 2 days in three ICUs b...

The aims of this study were to compare perineal distensibility between women with twin and singleton pregnancies and to correlate these women's perineal distensibility with anthropometric data. This prospective cross-sectional case-control study was conducted among nulliparous women, of whom 20 were pregnant with twins and 23 with a single fetus. Perineal distensibility was evaluated in the thi...

Aggressiveness and reproduction differed among four geographical populations of M. arenaria on six soybean cultivars in field microplots. These differences were consistent over 3 years. The populations did not differ in virulence; i.e., population by cultivar interactions were not significant. Perineal pattern morphology, the North Carolina differential host test, chromosome counts of immature ...

OBJECTIVES To determine trends and risk factors for severe perineal trauma between 2000 and 2008. DESIGN This was a population-based data study. SETTING New South Wales, Australia. PARTICIPANTS 510 006 women giving birth to a singleton baby during the period 2000-2008. MAIN OUTCOME MEASURES Rates of severe perineal trauma between 2000 and 2008 and associated demographic, fetal, antenata...

Background. Perineal pressure due to bicycle riding has been associated with erectile dysfunction. We developed a novel method to measure the occlusive force exerted over the perineal arteries and determined perineal artery occlusion by a variety of seat designs. Methods. Doppler ultrasonography facilitated perineal artery localization and determination of the force required for perineal artery...

OBJECTIVES To report the surgical anatomy of the muscles of the urogenital diaphragm and the pattern of its vessels in the classic exstrophy bladder and incontinent epispadias. METHODS A total of 11 patients, 9 with unoperated classic exstrophy and 2 with incontinent epispadias, who were >5 years old at presentation, were selected for the present study. Magnetic resonance imaging of the pelvi...
