A newborn male infant presented with the “renal nonfunction syndrome” and subsequently was found at autopsy to have congenital stenosis of the posterior urethra. Additional urinary tract malformations included a prostatic diverticulum, bladder hypertrophy, bilateral hydroureter, and bilateral renal hypoplasia with dysplasia. Autopsy evidence suggested that the urethral stenosis had manifested itself very early during embryologic development and accounted for the associated urinary anomalies. The infant had the physical stigmata, clinical course, and pulmonary hypoplasia commonly observed in “Potter’s” or the “renal nonfunction syndrome.” 相似文献
Mesenteric blood vessels were examined in postmortem specimens of 30 selected infants. The infants had had necrotizing enterocolitis (16 cases) or other lesions (14 cases). Mesenteric thromboemboli were observed in 12 of the infants with necrotizing enterocolitis (P less than 0.001). Umbilical vessel catheters were apparently responsible for the emboli. Multiple instances of thrombosis and thromboembolism were detected in other organs. Ninety-four percent of infants with necrotizing enterocolitis were orally fed (P less than 0.001). Mesenteric thromboemboli were more frequent in infants who were fed via the digestive route while an umbilical arterial catheter was in place. Mesenteric thromboembolism in these infants was postulated to have been attributable to increased postprandial blood flow in the mesenteric vessels. 相似文献

Mixed-gender threesomes (MGTs) are a type of consensually nonmonogamous sexual encounter involving three people of more than one gender. Little research has been conducted on MGTs, and what little work does exist is limited to college students, who may actually be less experienced with MGTs than older adults. The present study investigated attitudes toward, interest in, experiences with, and outcomes of MGTs in two samples (college N?=?231; online N?=?1342), comprised of 907 heterosexual and 666 sexual minority participants in total. Results indicated that participants reported neutral-to-positive attitudes toward and moderate-to-high levels of interest in MGTs (81% indicated some degree of interest). MGTs involving familiar others were preferred to those involving strangers. Men, sexual minority individuals, and participants from the online sample reported more favorable attitudes toward and greater interest in MGTs as compared to women, heterosexual individuals, and participants from the student sample. In addition, 30% of participants indicated having experience with a MGT. Sexual minority individuals reported more experience with MGTs and more positive outcomes than did heterosexual individuals. In addition, on average, participants reported that their MGT experiences “met expectations.” Overall, these results indicate that MGTs are a common sexual behavior that often results in positive outcomes, especially among sexual minority individuals. Additional research on this understudied topic is needed, particularly as it relates to outcomes and the role of MGTs in consensually nonmonogamous relationships.
Cuckolding (also known as troilism) is a sexual interest in which one obtains sexual arousal from the experience of a romantic partner engaging in sexual activity with someone else. The present study investigated fantasies about and experiences with cuckolding in a large and diverse sample of predominately gay-identified men (N = 580). Compared to previous research focusing on heterosexual men’s cuckolding fantasies, our results indicate that gay men’s cuckolding fantasies share many common elements; however, they differ in some important ways. Most notably, interracial and BDSM themes do not appear to be as common in gay men’s cuckolding fantasies as they are among heterosexual men. Our findings also indicate that frequent fantasies about cuckolding are linked to several overlapping sexual interests (e.g., voyeurism, group sex) and, further, the content of these fantasies is associated with a number of individual differences (e.g., agreeableness, sensation seeking, sociosexuality). Finally, this study also suggests that gay men who act on their cuckolding fantasies tend to report positive experiences; however, the likelihood of reporting positive outcomes appears to depend upon one’s personality and attachment style. 相似文献
