    LPP (Lipoma Preferred Partner) is a zyxin-related cell adhesion protein that is involved in the regulation of cell migration. We generated mice with a targeted disruption of the Lpp gene and analysed the importance of Lpp for embryonic development and adult functions. Aberrant Mendelian inheritance in heterozygous crosses suggested partial embryonic lethality of Lpp{sup -/-} females. Fertility of Lpp{sup -/-} males was proven to be normal, however, females from Lpp{sup -/-} x Lpp{sup -/-} crosses produced a strongly reduced number of offspring, probably due to a combination of female embryonic lethality and aberrant pregnancies. Apart from these developmental and reproductive abnormalities, Lpp{sup -/-} mice that were born reached adulthood without displaying any additional macroscopic defects. On the other hand, Lpp{sup -/-} mouse embryonic fibroblasts exhibited reduced migration capacity, reduced viability, and reduced expression of some Lpp interaction partners. Finally, we discovered a short nuclear form of Lpp, expressed mainly in testis via an alternative promoter.

    Here, we identify the LIM protein lipoma-preferred partner (LPP) as a binding partner of a specific protein phosphatase 2A (PP2A) heterotrimer that is characterised by the regulatory PR130/B″α1 subunit (encoded by PPP2R3A). The PR130 subunit interacts with the LIM domains of LPP through a conserved Zn2+-finger-like motif in the differentially spliced N-terminus of PR130. Isolated LPP-associated PP2A complexes are catalytically active. PR130 colocalises with LPP at multiple locations within cells, including focal contacts, but is specifically excluded from mature focal adhesions, where LPP is still present. An LPP–PR130 fusion protein only localises to focal adhesions upon deletion of the domain of PR130 that binds to the PP2A catalytic subunit (PP2A/C), suggesting that PR130–LPP complex formation is dynamic and that permanent recruitment of PP2A activity might be unfavourable for focal adhesion maturation. Accordingly, siRNA-mediated knockdown of PR130 increases adhesion of HT1080 fibrosarcoma cells onto collagen I and decreases their migration in scratch wound and Transwell assays. Complex formation with LPP is mandatory for these PR130-PP2A functions, as neither phenotype can be rescued by re-expression of a PR130 mutant that no longer binds to LPP. Our data highlight the importance of specific, locally recruited PP2A complexes in cell adhesion and migration dynamics. PMID:26945059

    Prolonged hemodynamic load as a result of hypertension eventually leads to maladaptive cardiac adaptation and heart failure. The signaling pathways that underlie these changes are still poorly understood. The adaptive response to mechanical load is mediated by mechanosensors that convert the mechanical stimuli into a biological response. We examined the effect of cyclic mechanical stretch on myocyte adaptation using neonatal rat ventricular myocytes with 10% (adaptive) or 20% (maladaptive) maximum strain at 1 Hz for 48 h to mimic in vivo mechanical stress. Cells were also treated with and without nitro-L-arginine methyl ester (L-NAME), a general nitric oxide synthase (NOS) inhibitor to suppress NO production. Maladaptive 20% mechanical stretch led to a significant loss of intact sarcomeres that were rescued by L-NAME (P < 0.05; n ≥ 5 cultures). We hypothesized that the mechanism was through NO-induced alteration of myocyte gene expression. L-NAME upregulated the mechanosensing proteins muscle LIM protein (MLP; by 100%; P < 0.05; n = 5 cultures) and lipoma preferred partner (LPP), a novel cardiac protein (by 80%; P < 0.05; n = 4 cultures). L-NAME also significantly altered the subcellular localization of LPP and MLP in a manner that favored growth and adaptation. These findings suggest that NO participates in stretch-mediated adaptation. The use of isoform selective NOS inhibitors indicated a complex interaction between inducible NOS and neuronal NOS isoforms regulate gene expression. LPP knockdown by small intefering RNA led to formation of α-actinin aggregates and Z bodies showing that myofibrillogenesis was impaired. There was an upregulation of E3 ubiquitin ligase (MUL1) by 75% (P < 0.05; n = 5 cultures). This indicates that NO contributes to stretch-mediated adaptation via the upregulation of proteins associated with mechansensing and myofibrillogenesis, thereby presenting potential therapeutic targets during the progression of heart failure.

  4. Sexual partner preference in female Japanese macaques.

    Whether animals ever exhibit a preference for same-sex sexual partners is a subject of debate. Japanese macaques represent excellent models for examining issues related to sexual preference in animals because females, in certain populations, routinely engage in both heterosexual and homosexual behavior over the course of their life spans. Multiple lines of evidence indicate that female homosexual behavior in Japanese macaques is a sexual behavior, not a sociosexual one. Additional evidence indicates that female Japanese macaques do not engage in homosexual behavior simply because acceptable male mates are unavailable or unmotivated to copulate. Patterns of sexual partner choice by female Japanese macaques that are the focus of intersexual competition indicate that females of this species choose same-sex sexual partners even when they are simultaneously presented with a motivated, opposite-sex alternative. Thus, in some populations of Japanese macaques, females prefer certain same-sex sexual partners relative to certain male mates, and vice versa. Taken together, this evidence suggests that female Japanese macaques are best characterized as bisexual in orientation, not preferentially homosexual or preferentially heterosexual.

  5. Partner preferences among survivors of betrayal trauma.

    Betrayal trauma theory suggests that social and cognitive development may be affected by early trauma such that individuals develop survival strategies, particularly dissociation and lack of betrayal awareness, that may place them at risk for further victimization. Several experiences of victimization in the context of relationships predicated on trust and dependence may contribute to the development of relational schema whereby abuse is perceived as normal. The current exploratory study investigates interpersonal trauma as an early experience that might impact the traits that are desired in potential romantic partners. Participants in the current study were asked to rate the desirability of several characteristics in potential romantic partners. Although loyalty was desirable to most participants regardless of their trauma history, those who reported experiences of high betrayal trauma rated loyalty less desirable than those who reported experiences of traumas that were low and medium in betrayal. Participants who reported experiences of revictimization (defined as the experience of trauma perpetrated by a close other during 2 different developmental periods) differed from participants who only reported 1 experience of high betrayal trauma in their self-reported desire for a romantic partner who possessed the traits of sincerity and trustworthiness. Preference for a partner who uses the tactic of verbal aggression was also associated with revictimization status. These preliminary findings suggest that victimization perpetrated by close others may affect partner preferences.

    In two large Turkish consanguineous families, a locus for autosomal recessive nonsyndromic hearing loss (ARNSHL) was mapped to chromosome 6p21.3 by genome-wide linkage analysis in an interval overlapping with the loci DFNB53 (COL11A2), DFNB66, and DFNB67. Fine mapping excluded DFNB53 and subsequently homozygous mutations were identified in the lipoma HMGIC fusion partner-like 5 (LHFPL5) gene, also named tetraspan membrane protein of hair cell stereocilia (TMHS) gene, which was recently shown to be mutated in the "hurry scurry" mouse and in two DFNB67-linked families from Pakistan. In one family, we found a homozygous one-base pair deletion, c.649delG (p.Glu216ArgfsX26) and in the other family we identified a homozygous transition c.494C>T (p.Thr165Met). Further screening of index patients from 96 Turkish ARNSHL families and 90 Dutch ARNSHL patients identified one additional Turkish family carrying the c.649delG mutation. Haplotype analysis revealed that the c.649delG mutation was located on a common haplotype in both families. Mutation screening of the LHFPL5 homologs LHFPL3 and LHFPL4 did not reveal any disease causing mutation. Our findings indicate that LHFPL5 is essential for normal function of the human cochlea.

    Previous research has shown repeatedly that human stature influences mate preferences and mate choice in heterosexuals. In general, it has been shown that tall men and average height women are most preferred by the opposite sex, and that both sexes prefer to be in a relationship where the man is taller than the woman. However, little is known about such partner preferences in homosexual individuals. Based on an online survey of a large sample of non-heterosexual men (N = 541), we found that the majority of men prefer a partner slightly taller than themselves. However, these preferences were dependent on the participant's own height, such that taller men preferred shorter partners, whereas shorter men preferred taller partners. We also examined whether height preferences predicted the preference for dominance and the adoption of particular sexual roles within a couple. Although a large proportion of men preferred to be in an egalitarian relationship with respect to preferred dominance (although not with respect to preferred sexual role), men that preferred a more dominant and more "active" sexual role preferred shorter partners, whereas those that preferred a more submissive and more "passive" sexual role preferred taller partners. Our results indicate that preferences for relative height in homosexual men are modulated by own height, preferred dominance and sex role, and do not simply resemble those of heterosexual women or men.

    Lipomas of the heart are encapsulated tumors that are composed primarily of mature fat cells. Cardiac lipomas can originate either from subendocardium (approximately 50%), subpericardium (25%), or from the myocardium (25%) and may be located more frequently in left ventricle or right atrium. We report a 74-year-old female who presented with dyspnea on exertion and was found to have 5×5 cm mass occupying most of the right atrium on a transesophageal echocardiogram. PMID:26486106

    Neonatal handling is an experimental procedure used to understand how early-life adversity can negatively affect neurobehavioral development and place animals on a pathway to pathology. Decreased preference for the maternal odor during infancy is one of many behavioral deficits induced by neonatal handling. Here, we hypothesize that deficits in maternal odor preference may interfere with partner preference in the adult. To test this hypothesis, we assessed infant maternal odor preference and adult partner preference in different reproductive stages in both male and female rats that received neonatal handling. Our results indicate that only neonatally handled females present deficits in maternal odor preference during infancy, but both male and females present deficits in adult partner preference. However, sexual experience was effective in rescuing partner preference deficits in males. These results indicate that, considering infant and adult social interactions, females are more susceptible to the effects of neonatal handling than males.

  11. The Neurobiology of Sexual Partner Preferences in Rams

    2009-01-01

    The question of what causes a male animal to seek out and choose a female as opposed to another male mating partner is unresolved and remains an issue of considerable debate. The most developed biologic theory is the perinatal organizational hypothesis, which states that perinatal hormone exposure mediates sexual differentiation of the brain. Numerous animal experiments have assessed the contribution of perinatal testosterone and/or estradiol exposure to the development of a male-typical mate preference, but almost all have used hormonally manipulated animals. In contrast, variations in sexual partner preferences occur spontaneously in domestic rams, with as many as 8% of the population exhibiting a preference for same-sex mating partners (male-oriented rams). Thus, the domestic ram is an excellent experimental model to study possible links between fetal neuroendocrine programming of neural mechanisms and adult sexual partner preferences. In this review, we present an overview of sexual differentiation in relation to sexual partner preferences. We then summarize results that test the relevance of the organizational hypothesis to expression of same-sex sexual partner preferences in rams. Finally, we demonstrate that the sexual differentiation of brain and behavior in sheep do not depend critically on aromatization of testosterone to estradiol. PMID:19446078

    Several preference studies comparing a short-acting with a longer-acting phosphodiesterase type 5 inhibitor have been conducted in men. Most men in those studies preferred tadalafil rather than sildenafil, and recent post hoc analysis of one study described several factors associated with men's treatment preference. No prospective studies have investigated the woman partners' preferences. To investigate the treatment preference of women who were partners of men using oral medications for erectile dysfunction (ED) in a single-center open-label crossover study. One hundred heterosexual couples in stable relationships, with male partners having ED based on the erectile function subscale of the International Index of Erectile Function, were randomly assigned to receive sildenafil or tadalafil for a 12-week phase, followed by another 12-week period using the alternate drug. Male and female participants completed sexual event diaries during both study phases, and the female participants were interviewed at baseline, midpoint, and end of study. Primary outcome data were the women's final interviews during which they were asked which drug they preferred and their reasons for that preference. A total of 79.2% of the women preferred their partners' use of tadalafil, while 15.6% preferred sildenafil. Preference was not affected by age or treatment order randomization. Women preferring tadalafil reported feeling more relaxed, experiencing less pressure, and enjoying a more natural or spontaneous sexual experience as reasons for their choice. Mean number of tablets used, events recorded, events per week, and days between events were not significantly different during each study phase. Women's preferences were similar to men when using these two drugs. While the women's reasons for preferring tadalafil emphasized relaxed, satisfying, longer-lasting sexual experiences, those preferring sildenafil focused on satisfaction and drug effectiveness for their partner.

    Lipomas are common benign soft tissue tumors whose genetic and cytogenetic features are well characterized. The karyotype is usually near- or pseudodiploid with characteristic structural chromosomal aberrations. The most common rearrangements target the high mobility group AT-hook 2 (HMGA2) gene in 12q14.3, with breakpoints occurring within or outside of the gene locus leading to deregulation of HMGA2. The most common fusion partner for HMGA2 in lipoma is lipoma-preferred partner (3q27), but also other genes frequently recombine with HMGA2. Furthermore, truncated HMGA2 transcripts are recurrently observed in lipomas. The present study describes 5 lipomas carrying the translocation t(4;12)(q27~28;q14~15) as the sole chromosomal anomaly, as well as 1 lipoma in which the three-way translocation t(1;4;12)(q21;q27~28;q14~15) was identified. Molecular analyses performed on 4 of these cases detected 4 truncated forms of HMGA2. In 3 tumors, the HMGA2 truncated transcripts included sequences originating from the chromosomal sub-band 4q28.1. Notably, in 2 of these cases, the fourth exon of HMGA2 was fused to transposable elements located in 4q28.1.

    A majority of birds are socially monogamous, providing exceptional opportunities to discover neuroendocrine mechanisms underlying preferences for opposite-sex partners where the sexes form extended affiliative relationships. Zebra finches have been the focus of the most systematic program of research to date in any socially monogamous animal. In this species, sexual partner preference can be partially or largely sex reversed with hormone manipulations during early development, suggesting a role for organizational hormone actions. This same conclusion emerges from research with Japanese quail, which do not form long-term pairs. In zebra finches, social experience manipulations during juvenile development also can sex reverse partner preference, either alone or in combination with an early hormone manipulation. Although there are several candidate brain regions where neural mechanisms could underlie these effects of hormones or social experience, the necessary research has not yet been done to determine their involvement. The neuroendocrinology of avian sexual partner preference is still frontier territory. Copyright © 2011 Elsevier Inc. All rights reserved.

    Female rats show conditioned place preference following paced copulation, and we have recently demonstrated that pairing almond odor with paced copulation induces a conditioned partner preference for almond-scented males. The present study examined whether cues of two different strains of male (albino and pigmented) induce a conditioned partner preference for the strain of male associated with paced copulation. Ovariectomized, hormone-primed Wistar (W) or Long-Evans (LE) female rats received 10 conditioning trials at 4-day intervals. In the Wistar-pacing group females copulated with W males in a chamber bisected by a 4-hole partition that only the female could pass through. Four days later, they copulated with LE males without the partition. The Long-Evans-pacing group received the opposite association. In the final preference test all females chose freely between two males tethered in opposite corners of an open field, one W and one LE. Regardless the strain of male, females displayed more solicitations toward the pacing-related male, and most of the females received their first ejaculation from that male. The preference was facilitated if the pacing-related male was of the same strain as the female. These results suggest that female rats have an unconditioned preference for males of the same strain, but this preference can be switched towards males of a different strain if that male is associated with the sexual reward induced by paced copulation.

    Lipomas are the most common benign mesenchymal neoplasm in adults, and have been extensively characterized at the cytogenetic level. Chromosomal aberrations have been observed in the majority of lipomas, two-thirds of which involve chromosomal region 12q14.3. To date, structural rearrangements have been reported affecting every chromosome except chromosome Y. Here we report a case of a lipoma that shows a novel apparently balanced translocation involving chromosomes Y and 12. Fluorescence in situ hybridization using a break-apart HMGA2 in-house probe set detected a single signal on the normal chromosome 12 but not on either the derivative chromosome Y or 12, indicating a cryptic loss of 12q14.3, where HMGA2 is mapped. Immunohistochemical studies, however, revealed overexpression of HMGA2 with nuclear expression in the majority of tumor cells, whereas MDM2 and CDK4 were negative. The overexpression of HMGA2 may be caused by a cryptic chromosomal aberration affecting either the cytogenetically unaltered HMGA2 allele or HMGA2 regulators elsewhere. The current case broadens our knowledge about the translocation partners of HMGA2 in lipomas and highlights the biological complexity in regulating HMGA2 expression.

    Intracranial lipomas in an infratentorial and extra-axial location are extremely rare. The presented case of an extensive lipoma of the cerebellopontine angle (CPA) represents 0.05% of all CPA tumors operated on in our department from 1978 to 1996. The lipoma constitutes an important differential diagnosis because the clinical management differs significantly from other CPA lesions. The clinical presentation and management of the presented case are analyzed in comparison to all previously described cases of CPA lipomas. The etiology and the radiological features of CPA lipomas are reviewed and discussed. CPA lipomas are maldevelopmental lesions that may cause slowly progressive symptoms. Neuroradiology enables a reliable preoperative diagnosis. Attempts of complete lipoma resection usually result in severe neurological deficits. Therefore, we recommend a conservative approach in managing these patients. Limited surgery is indicated if the patient has an associated vascular compression syndrome or suffers from disabling vertigo. ImagesFigure 1Figure 2Figure 3Figure 4 PMID:17171031

  2. Sex differences in partner preferences in humans and animals.

    2016-02-19

    A large number of morphological, physiological and behavioural traits are differentially expressed by males and females in all vertebrates including humans. These sex differences, sometimes, reflect the different hormonal environment of the adults, but they often remain present after subjects of both sexes are placed in the same endocrine conditions following gonadectomy associated or not with hormonal replacement therapy. They are then the result of combined influences of organizational actions of sex steroids acting early during development, or genetic differences between the sexes, or epigenetic mechanisms differentially affecting males and females. Sexual partner preference is a sexually differentiated behavioural trait that is clearly controlled in animals by the same type of mechanisms. This is also probably true in humans, even if critical experiments that would be needed to obtain scientific proof of this assertion are often impossible for pragmatic or ethical reasons. Clinical, epidemiological and correlative studies provide, however, converging evidence strongly suggesting, if not demonstrating, that endocrine, genetic and epigenetic mechanisms acting during the pre- or perinatal life control human sexual orientation, i.e. homosexuality versus heterosexuality. Whether they interact with postnatal psychosexual influences remains, however, unclear at present.

    The sexual age preferences of 192 adults (equal groups of heterosexual men, heterosexual women, homosexual men, and homosexual women) were examined. Participants rated the sexual attractiveness of pictures of 15 male and 15 female faces arranged into five apparent average age categories ranging from 18 to 60 years. It was predicted that homosexual and heterosexual men would prefer younger partners of their preferred sex than would homosexual and heterosexual women and that age preference would not vary with participant age. Both predictions were supported, although homosexual women preferred older partners than expected. Results suggest that age and sex preferences develop independently.

  5. Correlated Preferences for Male Facial Masculinity and Partner Traits in Gay and Bisexual Men in China.

    Previous studies have documented the correlation between preferences for male facial masculinity and perceived masculinity: women who rate their male partner as more masculine tend to prefer more masculine faces. Men's self-rated masculinity predicts their female partner's preference for masculinity. This study examined the association between other trait preferences and preference for male facial masculinity among 556 gay and bisexual men across multiple cities in China. Participants were asked to choose the three most important traits in a romantic partner from a list of 23 traits. Each participant was then asked to choose a preferred face in each of 10 pairs of male faces presented sequentially, with each pair consisting of a masculinized and feminized version of the same base face. The results indicated that preferences for health and status-related traits were correlated with preferences for male facial masculinity in gay and bisexual men in China; individuals who were more health- or status-oriented in their preferences for a romantic partner preferred more masculine male faces than individuals with lower levels of these orientations. The findings have implications for the correlated preferences for facial masculinity and health- and status-related traits and may be related to perceived health and dominance/aggression of masculine faces based on a sample of non-Western gay and bisexual men.

    Peer influence and social networking can change female adolescent and young adult behavior. Peer influence on preferences for male human papillomavirus (HPV) vaccination has not been documented. The primary aim of this study was to determine if women had preferences about male sexual partner HPV vaccination receipt. A prospective survey of women 18-26 years of age was conducted at an urban university student health clinic. Education about the two HPV vaccines, cervical cancer and genital warts was provided. Women self-reported their demographic and medical history data, as well as their own preferences for HPV vaccine and their preferences for their male partner HPV vaccine using a 5 point Likert scale. 601 women, mean age of 21.5 years (SD 2.4), participated between 2011 and 2012. Nearly 95% of respondents were heterosexual; condoms and contraceptives were used in over half of the population. Regardless of the woman's vaccination status, women had significantly higher (strongly agree/agree) preferences for the male partner being vaccinated with HPV4 than not caring if he was vaccinated (63.6% vs. 13.1%, p<0.001). This preference was repeated for sexual risk factors and past reproductive medical history. Women who received HPV4 compared to those choosing HPV2 had a significantly lower proportion of preferences for not caring if the male partner was vaccinated (13% vs. 22%, p = 0.015). Women preferred a HPV vaccinated male partner. Peer messaging might change the male HPV vaccination uptake.

  7. When and why do ideal partner preferences affect the process of initiating and maintaining romantic relationships?

    Three studies explored how the traits that people ideally desire in a romantic partner, or ideal partner preferences, intersect with the process of romantic relationship initiation and maintenance. Two attraction experiments in the laboratory found that, when participants evaluated a potential romantic partner's written profile, they expressed more romantic interest in a partner whose traits were manipulated to match (vs. mismatch) their idiosyncratic ideals. However, after a live interaction with the partner, the match vs. mismatch manipulation was no longer associated with romantic interest. This pattern appeared to have emerged because participants reinterpreted the meaning of the traits as they applied to the partner, a context effect predicted by classic models of person perception (S. E. Asch, 1946). Finally, a longitudinal study of middle-aged adults demonstrated that participants evaluated a current romantic partner (but not a partner who was merely desired) more positively to the extent that the partner matched their overall pattern of ideals across several traits; the match in level of ideals (i.e., high vs. low ratings) was not relevant to participants' evaluations. In general, the match between ideals and a partner's traits may predict relational outcomes when participants are learning about a partner in the abstract and when they are actually in a relationship with the partner, but not when considering potential dating partners they have met in person.

  8. Trichostatin A (TSA) facilitates formation of partner preference in male prairie voles (Microtus ochrogaster).

    In the socially monogamous prairie voles (Microtus ochrogaster), the development of a social bonding is indicated by the formation of partner preference, which involves a variety of environmental and neurochemical factors and brain structures. In a most recent study in female prairie voles, we found that treatment with the histone deacetylase inhibitor trichostatin A (TSA) facilitates the formation of partner preference through up-regulation of oxytocin receptor (OTR) and vasopressin V1a receptor (V1aR) genes expression in the nucleus accumbens (NAcc). In the present study, we tested the hypothesis that TSA treatment also facilitates partner preference formation and alters OTR and V1aR genes expression in the NAcc in male prairie voles. We thus observed that central injection of TSA dose-dependently promoted the formation of partner preference in the absence of mating in male prairie voles. Interestingly, TSA treatment up-regulated OTR, but not V1aR, gene expression in the NAcc similarly as they were affected by mating - an essential process for naturally occurring partner preference. These data, together with others, not only indicate the involvement of epigenetic events but also the potential role of NAcc oxytocin in the regulation of partner preference in both male and female prairie voles.

    Sexual partner preferences can be strengthened, weakened or even drastically modified via Pavlovian conditioning. For example, conditioned same-sex partner preference develops in sexually-naïve male rats that undergo same-sex cohabitation under the effects of quinpirole (QNP, D2 agonist). Here, we assessed the effect of prior heterosexual experience on the probability to develop a conditioned same-sex preference. Naïve or Sexually-experienced males received either Saline or QNP and cohabited during 24h with a male partner that bore almond scent on the back as conditioned stimulus. This was repeated every 4days for a total of three trials and resulted in four groups (Saline-naïve, Saline-experienced, QNP-naïve, QNP-experienced). Social and sexual preference were assessed four days after the last conditioning trial in a drug-free test in which experimental males chose between the scented familiar male and a novel sexually receptive female. Results showed that Saline-naïve, Saline-experienced and QNP-experienced displayed a clear preference for the female (opposite-sex). By contrast, only QNP-naïve males displayed a same-sex preference. Accordingly, QNP-experienced males were not affected by the conditioning process and continued to prefer females. We discuss the effects of copulation and D2 agonists on the facilitation and/or disruption of conditioned partner preferences.

    A central element of interdependence theory is that people have standards against which they compare their current outcomes, and one ubiquitous standard in the mating domain is the preference for particular attributes in a partner (ideal partner preferences). This article reviews research on the predictive validity of ideal partner preferences and presents a new integrative model that highlights when and why ideals succeed or fail to predict relational outcomes. Section 1 examines predictive validity by reviewing research on sex differences in the preference for physical attractiveness and earning prospects. Men and women reliably differ in the extent to which these qualities affect their romantic evaluations of hypothetical targets. Yet a new meta-analysis spanning the attraction and relationships literatures (k = 97) revealed that physical attractiveness predicted romantic evaluations with a moderate-to-strong effect size (r = ∼.40) for both sexes, and earning prospects predicted romantic evaluations with a small effect size (r = ∼.10) for both sexes. Sex differences in the correlations were small (r difference = .03) and uniformly nonsignificant. Section 2 reviews research on individual differences in ideal partner preferences, drawing from several theoretical traditions to explain why ideals predict relational evaluations at different relationship stages. Furthermore, this literature also identifies alternative measures of ideal partner preferences that have stronger predictive validity in certain theoretically sensible contexts. Finally, a discussion highlights a new framework for conceptualizing the appeal of traits, the difference between live and hypothetical interactions, and the productive interplay between mating research and broader psychological theories.

    As more gay men are tested for antibodies to human immunodeficiency virus (HIV), serostatus may influence the formation of primary partner bonds in this community. We compared seropositive (n = 157), seronegative men (n = 205), and those who had not been tested (n = 158) from our ongoing AIDS Behavioral Research Project (total response in 1988 = 540). Subjects responded to mailed surveys regarding sexual behavior, relationship status, HIV antibody testing and serostatus preference when forming relationships for romance and friendship. Sixty-eight percent of seropositive gay male respondents reported no serostatus preference in partners for romance, while 83% of seronegative respondents and 74% of untested respondents preferred seronegative partners for romance. In addition, 15% of seronegative respondents and 12% of untested respondents preferred seronegative individuals for friendship. Seropositive individuals were much less likely to be desired for romance or friendship by seronegatives and those who have not been tested--at a time when emotional support and companionship are obviously needed.

    Studies of women's preferences for male faces have variously reported preferences for masculine faces, preferences for feminine faces and no effect of masculinity-femininity on male facial attractiveness. It has been suggested that these apparently inconsistent findings are, at least partly, due to differences in the methods used to manipulate the masculinity of face images or individual differences in attraction to facial cues associated with youth. Here, however, we show that women's preferences for masculinity manipulated in male faces using techniques similar to the three most widely used methods are positively inter-related. We also show that women's preferences for masculine male faces are positively related to ratings of the masculinity of their actual partner and their ideal partner. Correlations with partner masculinity were independent of real and ideal partner age, which were not associated with facial masculinity preference. Collectively, these findings suggest that variability among studies in their findings for women's masculinity preferences reflects individual differences in attraction to masculinity rather than differences in the methods used to manufacture stimuli, and are important for the interpretation of previous and future studies of facial masculinity.

    Female rats display a conditioned partner preference for males that bear odors paired with different types of rewarding unconditioned stimuli (UCS). Here we examined whether tickling constitutes a rewarding UCS that supports the development of partner preferences. In Experiment 1, we tested the possibility that odors associated with a tickling UCS in prepubescent rats would induce a conditioned partner preference in adulthood. Two groups were formed with 31-day-old, single-housed females, tickled for 6 min daily for 10 days, by a hand that wore a scented glove (almond or lemon). At 47 days of age, females were ovariectomized (OVX), hormone-primed (EB+P), and tested for sexual partner preference with two scented stud males (one almond and one lemon). In each group, females displayed a sexual preference toward males bearing the odor paired with tickling, as observed with longer visits, more solicitations, hops & darts, and receiving more intromissions and ejaculations from the preferred male. In Experiment 2, we used 3-month old, OVX, hormone-primed rats conditioned every 4 days for 10 trials. In contrast to juvenile females, adult females failed to prefer males that bore the odor paired with tickling but instead preferred the novel male. These results suggest that tickling has opposite age-dependent effects in the conditioning of partner preference. Tickling in juvenile females appears to act as a rewarding UCS, whereas in adult females it may act as an aversive UCS. Further research is needed to understand brain mechanisms that might account for such differences. Copyright © 2012 Elsevier Inc. All rights reserved.

    The central melanocortin (MC) system has been widely studied for its effects on food intake and sexual behavior. However, the MC system, and more specifically the MC4 receptor (MC4R), also interacts with neurochemical systems that regulate socioemotional behaviors, including oxytocin (OT) and dopamine. In monogamous prairie voles, OT and dopamine interact to promote partner preference formation, a laboratory measure of an enduring social bond between mates. Here we investigated the effects of MC receptor activation on partner preference formation in prairie voles, as well as the interaction between the MC and OT systems during this process. Peripheral administration of the brain penetrant MC3/4R receptor peptide agonist, Melanotan II (MTII), and the highly selective, small-molecule MC4R agonist, Pf-446687, enhanced partner preference formation in the prairie vole, but not in the non-monogamous meadow vole. MTII-induced partner preferences were enduring, as they were present 1 week after drug manipulation. The prosocial effects of MCR agonists may be mediated, in part, through modulation of OT, as coadministration of an OT receptor antagonist prevented MTII-induced partner preferences. MTII also selectively activated hypothalamic OT neurons and potentiated central OT release. As OT has been shown to enhance some aspects of social cognition in humans, our data suggest that the MC4R may be a viable therapeutic target for enhancing social function in psychiatric disorders, including autism spectrum disorders and schizophrenia, potentially through activation of the OT system.

    In the socially monogamous prairie vole (Microtus ochrogaster), mating induces enduring pair-bonds initiated by partner preference formation and regulated by a variety of neurotransmitters including oxytocin, vasopressin, and dopamine. Here we examined potential epigenetic mechanisms mediating pair-bond regulation. We show that the histone deacetylase inhibitors sodium butyrate and TrichoStatin A (TSA) facilitate partner preference formation in female prairie voles in the absence of mating. This was associated with a specific up-regulation of oxytocin (OTR) and vasopressin V1a receptors (V1aR) in the nucleus accumbens, through an increase in histone acetylation at their respective promoter. Furthermore, TSA-facilitated partner preference was prevented by OTR or V1aR blockade in the nucleus accumbens. Importantly, mating-induced partner preference triggered the same epigenetic regulation of OTR and V1aR gene promoters as TSA. These observations thus indicate that TSA and mating facilitate partner preference through epigenetic events, providing the first direct evidence for an epigenetic regulation of pair-bonding.

    The present study was designed to test the effects of an acute, high dose of methylphenidate (MPH; trademarked as Ritalin) on sexual behavior in female Long-Evans rats. In Experiment 1, naturally cycling subjects in estrus were tested for partner preference 20min after receiving an i.p. injection of MPH 10mg/kg (n=8) or saline (n=7). During the partner-preference test, female subjects were given the choice to interact with a sexually active male stimulus or a sexually receptive female stimulus. Physical contact was limited by placing the stimulus animals behind a wire mesh during the no-contact phase of the test, whereas physical contact was not limited during the contact phase. Female subjects that received MPH spent significantly less time with the male stimulus than the saline-treated subjects during both phases (no-contact and contact) of the partner-preference test. This acute dose of MPH did not affect visits to the female stimulus; however, MPH-treated subjects made fewer visits to the male stimulus than the saline-treated subjects during the contact phase of the partner-preference test. Consistent with previous findings, MPH increased line crossings when subjects were tested in an open field immediately after the partner-preference test. In Experiment 2, female subjects were ovariectomized (OVX), primed with estradiol benzoate and progesterone, and tested for partner preference 20min after receiving an injection of MPH 10mg/kg (n=8) or saline (n=8). Similar to the results of Experiment 1, OVX hormone-primed subjects that received MPH spent significantly less time with the male stimulus than the saline-treated subjects during both phases of the partner-preference test. Although MPH-treated subjects were sexually receptive, they displayed fewer proceptive behaviors (i.e., hops and darts) than saline-treated subjects. Two-weeks later, the subjects from Experiment 2 were tested in an open field 20min after receiving an injection of MPH 10mg/kg or saline

    Previous studies with prairie voles suggest that the hormone oxytocin is crucial for bond formation - indicated when a partner preference is formed towards the target vole. In this study, we conduct the first empirical test of whether oxytocin likewise promotes partner preferences in humans. Seventy-six undergraduate students received either oxytocin or placebo before being introduced to a male and female persona (via pre-recorded videoclips). One day later, participants were assessed for a partner preference towards the personae: across three situations, participants were asked to choose as company one of the personae they had been introduced to, or an opposite- or same-gendered person they had not been introduced to before; participants were additionally offered a choice to have no company. We found evidence suggesting oxytocin increases preference for persons introduced under the influence of oxytocin; however, this was not targeted at persons of the opposite-gender, and was found in only one aspect of social interaction (finding out more information about the person, but not in choice of company to work with or for a date). Taken together, our findings suggest that oxytocin might not promote human bond formation in ways analogous to prairie voles - that is, by inducing a partner preference effect.

  20. Reproductive ambition predicts partnered, but not unpartnered, women's preferences for masculine men.

    2012-08-01

    Changing circumstances alter the costs and benefits of choosing different mates and are thought to be reflected in women's mate preferences. Indeed, several lines of reasoning, and some prior studies, suggest that individual differences in women's preferences for cues of men's underlying health will be more apparent among partnered women than among unpartnered women. The current study shows that preferences for male faces with masculine shape cues, characteristics that are thought to signal men's underlying health, are positively correlated with partnered, but not unpartnered, women's reported reproductive ambition (i.e., their desire to become pregnant). These findings (1) present new evidence for systematic variation in women's mating strategies, (2) suggest that partnership status may be important for potentially adaptive variation in women's mate preferences, and (3) suggest that reproductive ambition may influence women's mate preferences. Alternative explanations for these findings, focusing on the possible effects of a range of variables that may be correlated with reproductive ambition in partnered women and influence their masculinity preferences, are also discussed.

    In the rat, neonatal administration of testosterone propionate to a castrated male causes masculinization of behavior. However, if an intact male is treated neonatally with testosterone (hyper-androgen condition), male sexual behavior in adulthood is disrupted. There is a possibility that the hyper-androgen treatment is suppressing male sexual behavior by altering the male’s partner preference and thereby reducing his motivation to approach the female. If so, this would suggest that exposure to supra-physiological levels of androgen during development may result in the development of male-oriented partner preference in the male. To test this idea, male rats were treated either postnatally or prenatally with testosterone, and partner preference and sexual behavior were examined in adulthood. The principal finding of this study was that increased levels of testosterone during early postnatal life, but not prenatal, decreased male sexual behavior and increased the amount of time a male spent with a stimulus male, without affecting the amount of time spent with a stimulus female during partner preference tests. Thus, the reduction in male sexual behavior produced by early exposure to high levels of testosterone is not likely due to a reduction in the male’s motivation to approach a receptive female.

    Lipomas are rare in oral and maxillofacial regions although they are the most common tumours of mesenchymal origin in human body. The etiology remains unclear. Various different theories explain the pathogenesis of this adipose tissue tumour and also different histological variants of oral lipoma have been given in literature. A case of intraoral lipoma occurring in mental region in a 77-year-old male is reported along with review of the literature. Wide surgical excision was performed and two-year followup showed excellent healing without any recurrence. Lipomas are benign soft tissue neoplasm of mature adipose tissue seen as a common entity in the head and neck region. Intraoral lipomas are a rare entity which may be noticed only during routine dental examinations. Most of them rarely cause pain, resulting in delay to seek treatment. It is mandatory for a clinician to diagnose intraoral lipomas using latest diagnostic methods and conservatively treat them without causing much discomfort. PMID:24592278

    Lipedema is an underdiagnosed syndrome of unclear etiology, characterized by symmetric painful enlargement of the buttocks and lower extremities, which spares the feet. This enlargement is caused by the deposition of adipose tissue. It was first described by Allen and Hines in 1940, who observed that it had a female predilection; patients commonly had an associated family history. We describe a patient with classic lipedema and multiple lipomas of her arms and trunk.

  5. The role of conditioning on heterosexual and homosexual partner preferences in rats

    PubMed Central

    Coria-Avila, Genaro A.

    2012-01-01

    Partner preferences are expressed by many social species, including humans. They are commonly observed as selective contacts with an individual, more time spent together, and directed courtship behavior that leads to selective copulation. This review discusses the effect of conditioning on the development of heterosexual and homosexual partner preferences in rodents. Learned preferences may develop when a conditioned stimulus (CS) is associated in contingency with an unconditioned stimulus (UCS) that functions as a reinforcer. Consequently, an individual may display preference for a partner that bears a CS. Some UCS may be more or less reinforcing, depending on when they are experienced, and may be different for males and females. For example, it could be that, only during periods of early development, that stimuli associated with nurture and juvenile play become conditioned. In adulthood, other stimuli such as sexual reward, cohabitation, mild stress, or even pharmacological manipulations may function as reinforcers to condition partner preferences. Evolutionary biologists and psychologists must take into consideration the idea that an individual’s experience with reward (i.e. sexual and pharmacological) can override presumably ‘innate’ mate choices (e.g. assortativeness and orientation) or mate strategies (e.g. monogamy or polygamy) by means of Pavlovian and operant contingencies. In fact, it is likely as innate to learn about the environment in ways that maximize reward and minimize aversive outcomes, making so-called ‘proximate’ causes (e.g. pleasure) ultimately more powerful predictors of social behavior and choice than so-called ‘ultimate’ causes (e.g. genetic or reproductive fitness).

    Body height influences human mate preferences and choice. A typical finding in Western societies is that women prefer men who are taller than themselves and, equivalently, men prefer women who are shorter than themselves. However, recent reports in non-Western societies (e.g., the Himba in Namibia) challenge the view on the universality of such preferences. Here we report on male and female height preferences in two non-Western populations--the Hadza (Tanzania) and the Tsimane' (Bolivia)--and the relationships between body height preferences and the height of actual partners. In the Hadza, most individuals preferred a sexual dimorphism in stature (SDS) with the man being much taller than the woman. Preferences for SDS and actual partner SDS were positively and significantly correlated in both men and women, suggesting that people who preferred larger height differences also had larger height differences with their partners. In the Tsimane', the majority of men preferred an SDS with the man being taller than the woman, but women did not show such a preference. Unlike in the Hadza, SDS preference was not significantly correlated to actual partner SDS. We conclude that patterns of height preferences and choices in the Hadza and Tsimane' are different than those observed in Western societies, and discuss possible causes for the observed differences between non-Western and Western societies.

  7. Kin preference and partner choice: patrilineal descent and biological kinship in Lamaleran cooperative relationships.

    PubMed

    Nolin, David A

    2011-07-01

    This paper presents a comparison of social kinship (patrilineage) and biological kinship (genetic relatedness) in predicting cooperative relationships in two different economic contexts in the fishing and whaling village of Lamalera, Indonesia. A previous analysis (Alvard, Human Nature 14:129-163, 2003) of boat crew affiliation data collected in the village in 1999 found that social kinship (patrilineage) was a better predictor of crew affiliation than was genetic kinship. A replication of this analysis using similar data collected in 2006 finds the same pattern: lineage is a better predictor than genetic kinship of crew affiliation, and the two together explain little additional variance over that explained by lineage alone. However, an analogous test on food-sharing relationships finds the opposite pattern: biological kinship is a better predictor of food-sharing relationships than is social kinship. The difference between these two cooperative contexts is interpreted in terms of kin preferences that shape partner choice, and the relative autonomy with which individuals can seek to satisfy those preferences. Drawing on stable matching theory, it is suggested that unilineal descent may serve as a stable compromise among multiple individuals' incongruent partner preferences, with patriliny favored over matriliny in the crew-formation context because it leads to higher mean degrees of relatedness among male cooperators. In the context of food-sharing, kin preferences can be pursued relatively autonomously, without the necessity of coordinating preferences with those of other households through the institution of lineage.

    Lipomas are the most common mesenchymal tumors.

    While the social interactions of Betta splendens have been studied in the contexts of dominance hierarchies, mate choice and communication networks, the social partner preferences of Betta have been largely overlooked. In this study, we presented male and female Betta with a single male, a single female, and a group of three females in dichotomous choice tests in order to better understand basic social interactions in this largely nonsocial species. The highly territorial Betta preferred associating with conspecifics in nearly every configuration we tested, with exceptions noted when single females were given the choice between a lone male and an empty chamber, and when males were presented with a single female and an empty chamber. Also, in most tests, the fish chose to spend more time with the larger group of females. The motivation for this preference certainly varied from reproductive to anti-predator. While such behavior might not suggest true shoaling behavior, it does demonstrate a subtle degree of sociality.

    Intimate partner violence (IPV) is a significant health issue faced by women veterans, but little is known about their preferences for IPV-related care. Five focus groups were conducted with 24 women Veterans Health Administration (VHA) patients with and without a lifetime history of IPV to understand their attitudes and preferences regarding IPV screening and responses within VHA. Women veterans wanted disclosure options, follow-up support, transparency in documentation, and VHA and community resources. They supported routine screening for IPV and articulated preferences for procedural aspects of screening. Women suggested that these procedures could be provided most effectively when delivered with sensitivity and connectedness. Findings can inform the development of IPV screening and response programs within VHA and other healthcare settings.

    Lipomas are rare benign tumors in the gastrointestinal system. Within the gastrointestinal system, 65% of the lipomas are located in the colon (sigmoid part of the colon or rectum) and rarely in the stomach and esophagus. The paper presents two gastrointestinal lipomas. First is the case of lipoma of the sigmoid colon and the other one is gastric lipoma. In both cases the material was sent for histopathological analysis due to suspicion of malignancy of the lesions. In both cases, the histopathologic analysis showed tumor made of mature adipocytes, localized in the submucosa both of the stomach and intestine. Hypercellularity and/or atypia of the cell was found in neither case. Lipomas are shown because of its atypical localization and clinically suspicious malignancy in the stomach and sigmoid colon. These cases show that the applied methods of preoperative diagnosis of tumors in the gastrointestinal system are not sufficient to determine the origin and biological behavior of tumors. Histopathological diagnosis provides a correct insight into the nature of tumors and determine the course of treatment. This paper presents a rare localization of lipomas in the gastrointestinal system. The preoperative diagnosis of lesions in the gastrointestinal system may not be sufficient to determine the origin and biological behavior of the lesions, hence the histopathological diagnosis gives an accurate insight into the nature of the change, preventing the possibility of further aggressive therapy.

  12. Oral contraceptive use in women changes preferences for male facial masculinity and is associated with partner facial masculinity.

    Millions of women use hormonal contraception and it has been suggested that such use may alter mate preferences. To examine the impact of oral contraceptive (pill) use on preferences, we tested for within-subject changes in preferences for masculine faces in women initiating pill use. Between two sessions, initiation of pill use significantly decreased women's preferences for male facial masculinity but did not influence preferences for same-sex faces. To test whether altered preference during pill use influences actual partner choice, we examined facial characteristics in 170 age-matched male partners of women who reported having either been using or not using the pill when the partnership was formed. Both facial measurements and perceptual judgements demonstrated that partners of women who used the pill during mate choice have less masculine faces than partners of women who did not use hormonal contraception at this time. Our data (A) provide the first experimental evidence that initiation of pill use in women causes changes in facial preferences and (B) documents downstream effects of these changes on real-life partner selection. Given that hormonal contraceptive use is widespread, effects of pill use on the processes of partner formation have important implications for relationship stability and may have other biologically relevant consequences.

    2012-01-01

    Esophageal lipomas are rare tumors, making up 0.4% of all digestive tract benign neoplasms. Most of these lesions are clinically silent as a result of their small size, however, the majority of lesions over 4 cm have been reported to cause dysphagia, regurgitation and/or epigastralgia. We report a case of a 53 year-old African American female who presented with dysphagia. Computed tomography of the chest and esophagram confirmed esophageal lipoma as the cause of the patient’s symptoms. Accurately diagnosing an esophageal lipoma is crucial in order to rule out potential malignant lesions, relieve patient symptoms and plan the appropriate treatment. PMID:23365708

    The effect of orgasm on the development and shaping of partner preferences may involve a catalysis of the neurochemical mechanisms of bonding. Therefore, understanding such process is relevant for neuroscience and psychology. A systematic review was carried out using the terms Orgasm, Sexual Reward, Partner Preference, Pair Bonding, Brain, Learning, Sex, Copulation. In humans, concentrations of arousing neurotransmitters and potential bonding neurotransmitters increase during orgasm in the cerebrospinal fluid and the bloodstream. Similarly, studies in animals indicate that those neurotransmitters (noradrenaline, oxytocin, prolactin) and others (e.g. dopamine, opioids, serotonin) modulate the appetitive and consummatory phases of sexual behavior and reward. This suggests a link between the experience of orgasm/sexual reward and the neurochemical mechanisms of pair bonding. Orgasm/reward functions as an unconditioned stimulus (UCS). Some areas in the nervous system function as UCS-detection centers, which become activated during orgasm. Partner-related cues function as conditioned stimuli (CS) and are processed in CS-detector centers. Throughout the article, we discuss how UCS- and CS-detection centers must interact to facilitate memory consolidation and produce recognition and motivation during future social encounters.

    The presence of a sexually receptive female behind perforated transparent partition induced sexual arousal and specific behavior in male mice so they spent more time near partition in an attempt to make their way to the female. Three-chambered free-choice model was used to evaluate sexual partner preference. The main pattern of sexual preference was the time spent by a male mouse at the partition dividing female (F-partition time) versus a partition dividing male (M-partition time). Pregnant mice were given ethanol (11vol.%) for 1-21 gestational days, and were exposed to restraint stress (2h daily for 15-21 day of the gestation). Control pregnant mice had free access to water and food and were not stressed. Adult male offspring of ethanol and stress exposed dams (E+S) showed decreased F-partition time and increased M-partition time. Whereas F-partition time in all control mice prevailed over M-partition time, 78% E+S mice demonstrated prevailed M-partition time. E+S mice were more active in social interaction with juvenile male. No significant differences between E+S and control mice in the open field and novelty tests were revealed. Therefore, E+S exposure during dam gestation inverted sexual partner preference in male offspring, suggesting that stress and alcohol in pregnancy produces predisposition to homosexuality.

    The dopamine D2-type receptor agonist quinpirole (QNP) facilitates the development of conditioned same-sex partner preference in males during cohabitation, but not in ovariectomized (OVX) females, primed with estradiol benzoate (EB) and progesterone (P). Herein we tested the effects of QNP on OVX, EB-only primed females. Females received a systemic injection (every four days) of either saline (Saline-conditioned) or QNP (QNP-conditioned) and then cohabited for 24h with lemon-scented stimulus females (CS+), during three trials. In test 1 (female-female) preference was QNP-free, and females chose between the CS+ female and a novel female. In test 2 (male-female) they chose between the CS+ female and a sexually experienced male. In test 1 Saline-conditioned females displayed more hops & darts towards the novel female, but QNP-conditioned females displayed more sexual solicitations towards the CS+ female. In test 2 Saline-conditioned females displayed a clear preference for the male, whereas QNP-conditioned females displayed what we considered a bisexual preference. We discuss the effect of dopamine and ovarian hormones on the development of olfactory conditioned same-sex preference in females. Copyright © 2017 Elsevier Inc. All rights reserved.

    2011-01-01

    The preference to seek out a sexual partner of the opposite sex is robust and ensures reproduction and survival of the species. Development of female-directed partner preference in the male is dependent on exposure of the developing brain to gonadal steroids synthesized during critical periods of sexual differentiation of the central nervous system. In the absence of androgen exposure, a male-directed partner preference develops. The development and expression of sexual partner preference has been extensively studied in rat, ferret, and sheep model systems. From these models it is clear that gonadal testosterone, often through estrogenic metabolites, cause both masculinization and defeminization of behavior during critical periods of brain development. Changes in the steroid environment during these critical periods result in atypical sexual partner preference. In this manuscript, we review the major findings which support the hypothesis that the organizational actions of sex steroids are responsible for sexual differentiation of sexual partner preferences in select non-human species. We also explore how this information has helped to frame our understanding of the biological influences on human sexual orientation and gender identity. PMID:22654808

  19. CRF receptors in the nucleus accumbens modulate partner preference in prairie voles

    Recent evidence suggests a role for corticotropin-releasing factor (CRF) in the regulation of pair bonding in prairie voles. We have previously shown that monogamous and non-monogamous vole species have dramatically different distributions of CRF receptor type 1 (CRF1) and CRF receptor type 2 (CRF2) in the brain, and that CRF1 and CRF2 receptor densities in the nucleus accumbens (NAcc) are correlated with social organization. Monogamous prairie and pine voles have significantly lower levels of CRF receptor type 1 (CRF1), and significantly higher levels of type 2 (CRF2) binding, in NAcc than non-monogamous meadow and montane voles. Here, we report that microinjections of CRF directly into the NAcc accelerate partner preference formation in male prairie voles. Control injections of CSF into NAcc, and CRF into caudate-putamen, did not facilitate partner preference. Likewise, CRF injections into NAcc of non-monogamous meadow voles also did not facilitate partner preference. In prairie voles, this CRF-facilitation effect was blocked by co-injection of either CRF1 or CRF2 receptor antagonists into NAcc. Immunocytochemical staining for CRF and Urocortin-1 (Ucn-1), two endogenous ligands for CRF1 or CRF2 receptors in the brain, revealed that CRF, but not Ucn-1, immunoreactive fibers were present in NAcc. This supports the hypothesis that local CRF release into NAcc could activate CRF1 or CRF2 receptors in the region. Taken together, our results reveal a novel role for accumbal CRF systems in social behavior. PMID:17320879

  20. Preferences for Social Support During Social Evaluation in Men: The Role of Worry About a Relationship Partner's Negative Evaluation.

    Most individuals seek proximity to support figures when distressed. However, individuals may not want a relationship partner present when their performance is being evaluated during difficult tasks, because they would worry about their partner's evaluation. Male participants' performance on difficult tasks was evaluated by critical judges. Then participants were asked if they wanted a close relationship partner present when they come back for similar tasks the following week. Worry about a partner's negative evaluation predicted not wanting the partner present. The direct effect of attachment-related anxiety on wanting more support was suppressed by its indirect effects in the opposite direction through distress and worry about a partner's negative evaluation. The indirect effect of attachment-related avoidance on wanting less support through distress and worry about partner's negative evaluation was also significant. Findings contribute to our understanding of preferences for support and effects on well-being.

    In most primate societies, strong and enduring social bonds form preferentially among kin, who benefit from cooperation through direct and indirect fitness gains. Chimpanzees, Pan troglodytes, differ from most species by showing consistent female-biased dispersal and strict male philopatry. In most East African populations, females tend to forage alone in small core areas and were long thought to have weak social bonds of little biological significance. Recent work in some populations is challenging this view. However, challenges remain in quantifying the influence of shared space use on association patterns, and in identifying the drivers of partner preferences and social bonds. Here, we use the largest data set on wild chimpanzee behaviour currently available to assess potential determinants of female association patterns. We quantify pairwise similarities in ranging, dyadic association and grooming for 624 unique dyads over 38 years, including 17 adult female kin dyads. To search for social preferences that could not be explained by spatial overlap alone, we controlled for expected association based on pairwise kernel volume intersections of core areas. We found that association frequencies among females with above-average overlap correlated positively with grooming rates, suggesting that associations reflected social preferences in these dyads. Furthermore, when available, females preferred kin over nonkin partners for association and grooming, and variability was high among nonkin dyads. While variability in association above and below expected values was high, on average, nonkin associated more frequently if they had immature male offspring, while having female offspring had the opposite effect. Dominance rank, an important determinant of reproductive success at Gombe, influenced associations primarily for low-ranking females, who associated preferentially with each other. Our findings support the hypothesis that female chimpanzees form well

    Female veterans are at high risk for intimate partner violence (IPV). A critical issue in the provision of health care to women who experience IPV is the delivery of effective brief counseling interventions that address women's unique needs. We aimed to identify female veterans' priorities and preferences for healthcare-based IPV counseling. A 2014 Web-based survey was administered to a national sample of US female veterans. Among 411 respondents (75% participation rate), 55% (n=226) reported IPV during their lifetime. These women identified priorities for the content focus of IPV-related counseling and preferences for the delivery of these services. Women prioritized counseling that focuses on physical safety and emotional health, with learning about community resources being a relatively lower priority. Participants preferred counseling to focus specifically on enhancing coping skills and managing mental health symptoms. In addition, women want counseling to be individualized and preferred the option to meet with a counselor immediately following disclosure. Affordable services and attention to privacy concerns were of paramount importance in the context of IPV-related counseling. These findings can inform patient-centered brief counseling interventions for women who experience IPV, which may ultimately reduce health disparities and violence among this population.

    2008-02-01

    In paradigms in which participants state their ideal romantic-partner preferences or examine vignettes and photographs, men value physical attractiveness more than women do, and women value earning prospects more than men do. Yet it remains unclear if these preferences remain sex differentiated in predicting desire for real-life potential partners (i.e., individuals whom one has actually met). In the present study, the authors explored this possibility using speed dating and longitudinal follow-up procedures. Replicating previous research, participants exhibited traditional sex differences when stating the importance of physical attractiveness and earning prospects in an ideal partner and ideal speed date. However, data revealed no sex differences in the associations between participants' romantic interest in real-life potential partners (met during and outside of speed dating) and the attractiveness and earning prospects of those partners. Furthermore, participants' ideal preferences, assessed before the speed-dating event, failed to predict what inspired their actual desire at the event. Results are discussed within the context of R. E. Nisbett and T. D. Wilson's (1977) seminal article: Even regarding such a consequential aspect of mental life as romantic-partner preferences, people may lack introspective awareness of what influences their judgments and behavior.

    Meralgia paresthetica (MP) consists of pain or dysthesia in the lateral thigh caused by entrapment of the lateral femoral cutaneous nerve (LFCN) underneath the inguinal ligament. The causes include iliac crest bone graft harvesting, seat belt injury associated with motor vehicle accident, diabetes mellitus, and trauma. The authors present the case of a 50-year-old woman who had a 1-year history of right-sided MP. The patient's history and the results of physical and radiological examinations were otherwise unremarkable except for the finding of a lipoma over the surface of the right sartorius muscle. Electrophysiological studies were interpreted as demonstrating peripheral neuropathy only. Conservative treatment, including heat or ice packing and local anesthetic and steroid injections, failed to control the patient's symptoms. Although sectioning or neurolysis of the LFCN appears to offer good-to-excellent results, the patient underwent excision of the lipoma. The symptoms resolved completely. To the best of the authors' knowledge this is the first case of MP associated with compression caused by a lipoma. The authors conclude that lipoma compression can cause MP, and in such cases, total excision of the lipoma may resolve the condition.

    Abstract Purpose: Human immunodeficiency virus (HIV) disproportionately affects men who have sex with men (MSM) in the United States. Most prior research into drivers of HIV transmission has focused on individual characteristics rather than on dyadic-level behaviors such as sex partner selection. This article explores racial/ethnic preferences in sex and relationship partner selection among MSM to further contextualize the spread of HIV within minority groups. Methods: Participants were recruited through a mobile application (app) for men to meet other men in 2015 and completed an online survey on behaviors related to HIV risk. All analyses on the sample of 530 MSM were conducted in 2015. Results: There was significant homophily in partner selection within racial/ethnic minorities, but not for white MSM. In general, mobile app-using MSM reported a general preference for white and Hispanic men and a dispreference for black and Asian men, both for sex and relationship partners. Conclusion: Racial/ethnic preferences were found to drive intentions to form partnerships within this sample. Combined with the stigma many of these racial/ethnic minorities may also feel from homophobic attitudes within their own racial/ethnic communities, these MSM may be at particular risk for social isolation. These partner preferences likely affect the structure of the sexual networks of MSM and may contribute to increased clustering within high HIV incident sexual networks. PMID:26907954

    Five studies develop and examine the predictive validity of an implicit measure of the preference for physical attractiveness in a romantic partner. Three hypotheses were generally supported. First, 2 variants of the go/no-go association task revealed that participants, on average, demonstrate an implicit preference (i.e., a positive spontaneous affective reaction) for physical attractiveness in a romantic partner. Second, these implicit measures were not redundant with a traditional explicit measure: The correlation between these constructs was .00 on average, and the implicit measures revealed no reliable sex differences, unlike the explicit measure. Third, explicit and implicit measures exhibited a double dissociation in predictive validity. Specifically, explicit preferences predicted the extent to which attractiveness was associated with participants' romantic interest in opposite-sex photographs but not their romantic interest in real-life opposite-sex speed-daters or confederates. Implicit preferences showed the opposite pattern. This research extends prior work on implicit processes in romantic relationships and offers the first demonstration that any measure of a preference for a particular characteristic in a romantic partner (an implicit measure of physical attractiveness, in this case) predicts individuals' evaluation of live potential romantic partners.

    We studied morphological changes of hydromyelia complicated with spinal lipoma of infants who were untethered. Since the MRI was introduced, early detection of spinal lipoma with lumbosacral skin abnormalities has become possible. We have experienced 44 surgical cases of spinal lipoma. Out of 36 such cases, 25 (69.4%) had hydromyelia, and hydromyelia of 9 patients was found to be of the terminal ventricle type. As many as 36% of spinal lipoma patients with hydromyelia concurrently had terminal-type hydromyelia, which was considered to fall under a specific category of congenital hydromyelia. At the stage of embryogenesis of the spinal cord, the caudal cell mass undergoes vacuolization, canalization and retrogressive differentiation, and during this process, the terminal ventricle with ependymallined cells becomes morbid. Though the morphological changes of hydromyelia after surgery as untethering were varied, hydromyelia of 9 patients became smaller after untethering, and hydromyelia of 8 expanded but attenuated afterwards, totaling 17 (68.0%). However, 5 had an expanding tendency and 3 did not show any morphological changes during the follow-up period (20.6-26.9 months) by MRI.

    The impact of erectile dysfunction is distressing to both males and their female partners, but less attention has been paid to identify female partners' preferred treatment and sexual quality of life outcomes. The present analysis explores female partners' treatment preference for erectile dysfunction in Chinese Men. This was a phase 4, randomized, open-label, multicenter, crossover study in Chinese men with erectile dysfunction who were naïve to phosphodiesterase type 5 inhibitor treatments. Eligible patients were randomized to sequential 20-mg tadalafil/100-mg sildenafil or 100-mg sildenafil/20-mg tadalafil for 8 weeks each. Of 418 patients, female partners of 64 patients agreed to enter the study; of 64 patients who entered the study with female partners, 63 were randomized, and 62 completed the study. Baseline demographics and disease characteristics were comparable between treatment groups. Significantly more couples preferred tadalafil compared with sildenafil overall (75.4% vs 24.6%; P < 0.001), and irrespective of erectile dysfunction severity at baseline (P ≤ 0.005). Significant improvements in sexual quality of life scores were reported at endpoint (Visit 8) in male patients and female partners in both tadalafil and sildenafil treatment groups (P < 0.001). Significantly higher mean changes from baseline were observed for male patients in the tadalafil group compared with the sildenafil group for the erectile function (P = 0.013) and overall satisfaction (P = 0.019) International Index for Erectile Function domains and the spontaneity domain (P < 0.001) of the Psychological and Interpersonal Relationship Scale. No major safety concerns were reported during the study. Though both treatments were effective, safe, and tolerable, more couples preferred tadalafil compared with sildenafil.

    We have shown previously that clitoral stimulation (CLS) of female rats induces significant conditioned place preference (CPP), indicating that it is rewarding. The present study asked whether CLS could induce a conditioned partner preference. In the first experiment, sexually naïve females received 10 alternating trials of CLS and No-CLS in the presence of a male rat behind a wire-mesh screen. For one group, CLS was made in the presence of the male scented with almond extract. On alternating trials, those females received sham CLS in the presence of an unscented male behind the screen. The order was reversed for the other group. After 5 trials in each condition, females were placed into an open field with two sexually vigorous males, one scented and the other unscented. Contrary to expectation, females displayed a preference for the male associated with sham CLS. The second experiment examined whether a partner preference could be conditioned by associating CLS with the almond odor alone. A new group of sexually naive females received the same CLS-odor, No-CLS-No Odor pairings as above, but with the odor presented on cotton gauze in the chamber. During the final open field test, those females selectively solicited the scented male. We conclude that CLS that induces CPP also induces conditioned partner preference. However, we propose that CLS in the presence of an inaccessible male created a sexual inhibitory state for female rats. Copyright © 2011 Elsevier Inc. All rights reserved.

    This study aimed to determine quantitatively the attributes of such screening tests that couples placed most value on. A stated preference discrete choice experiment was conducted among a sample of pregnant women and their male partners. One four-level attribute (cost) and three two-level attributes (detection rate, gestation and time to wait for results) were used to generate eight hypothetical pairs of tests. A total of 103 participants fully completed the questionnaire (63 women, 40 men). Overall, the sample was most concerned with test cost. However, latent class analysis showed three groups of participants whose concern for attributes differed, with cost, detection rate and delay in receiving results being the most important to each. Willingness to pay calculations showed that participants who were most concerned with detection rate were prepared to pay more than four times the amount than those most cost-sensitive would pay for the 'best test' option as compared with the 'worst test'. Overall, couples were sensitive to the price of the screening test, but explicit subgroups are also shown that would pay large amounts for improvements in other attributes, particularly detection rates. This could provide important information to policymakers and practitioners in antenatal care, specifically in relation to the trade-offs made when couples decide about antenatal screening tests. © 2013 John Wiley & Sons, Ltd.

    Intraoral lipomas are a rare clinical entity, comprising only 0.1% to 5% of all benign tumors in the intraoral cavity. A 56-year-old woman suffering from diabetes presented with this relatively rare intraoral lipoma and was treated by surgical excision under general anesthesia. Because the mass was located adjacent to the mental foramen, a precise dissection was necessary to ensure minimal nerve damage. No abnormalities or recurrence was noted at 1-year follow-up and the patient did not complain of numbness. We studied the occurrence of oral lipoma in this diabetic patient and reviewed the relationship between oral lipoma and diabetes in the literature. PMID:26339582

    Research suggest that Hispanics in the U.S. are disproportionately affected by the consequences of intimate partner violence. Nevertheless, few intimate partner violence prevention interventions have been developed to address the unique needs and preferences of this population. The Partnership for Domestic Violence Prevention is a community-based participatory research project that assessed the needs and preferences for prevention programs for Hispanics in Miami-Dade County. Nine focus groups with domestic violence service providers, victims and general community members were conducted (N= 76). Four major themes emerged from the focus groups. These included immigrants and teens as the highest priority groups to target in prevention efforts, culture as a double-edged sword, the system that helps and hurts the victim, and the need for wide-scale prevention programs that would reach Hispanics systematically. The results from this study have important implications for the development of intimate violence prevention interventions targeting Hispanics in the U.S. PMID:23843106

    The aim of this qualitative exploratory study was to assess the perceived needs and preferred services of male partners of women newly diagnosed with breast cancer. Twenty-seven male partners participated in semi-structured telephone interviews. Interviews were recorded and transcribed verbatim. An inductive analysis was used to identify the patterns, themes and categories from the data. A diagnosis of breast cancer and subsequent treatment significantly affect the male partners of women diagnosed with this illness, creating 'needs' that require coping responses. To help them support their wife and family, they relied on their internal resources and informal sources of support. Many participants suggested that the health care system provides information addressing their needs to facilitate their role of caring for their wife. The findings did not support the clinical assumption that men would be interested in a men's group focused on them and their needs. The diagnosis of breast cancer significantly affected the male partners, creating the need for support services including information on a variety of topics. An information binder tailored specifically to their needs was the preferred method of facilitating their husbandly role and coping. Findings did not support the clinical assumption that men would be interested in a men's group focused on them and their needs.

    An unusual case of bilateral intratentorial lipomas with extension into Meckel's caves and the cerebellopontine angle is described. Surgical and histopathologic correlation demonstrate that the lipoma encased the trigeminal nerve in Meckel's caves. The origin of the lipoma from the anteromedial margins of the tentorium is discussed and correlated with a recently proposed theory for the development of intracranial lipomas.

    Lipomas are benign tumors of mature adipocytes unusual in the oral and maxillofacial region. The average size of cheek lipomas in the literature ranges from 1.5 to 2.5 cm, with the maximum size of 5 cm. Their etiology remains unclear. Lipomas present, clinically, as well circumscribed, slow growing, painless masses, usually treated by complete excision. The aim of this paper is to present a 78-year-old Caucasian male patient with a huge cheek lipoma compromising facial esthetics and treated through an intraoral excision. Postoperative period was uneventful with no signs of recurrence. Concluding, the intraoral approach is a relatively simple technique that should be taken into account when considering the surgical removal of cheek lipomas.

    Introduction: Lipomas are among the most common tumors of the human body. However, they are uncommon in the oral cavity and are observed as slow growing, painless, and asymptomatic yellowish submucosal masses. Surgical excision is the treatment of choice and recurrence is not expected.  Case Report: The case of a 30-year-old woman with a huge lipoma on the tip of her tongue since 3 years, is presented. She had difficulty with speech and mastication because the tongue tumor was filling the oral cavity. Clinical examination revealed a yellowish lesion, measuring 8 cm in maximum diameter, protruding from the lingual surface. The tumor was surgically excised with restoration of normal tongue function and histopathological examination of the tumor confirmed that it was a lipoma. Conclusion: Tongue lipoma is rarely seen and can be a cause of macroglossia. Surgical excision for lipoma is indicated for symptomatic relief and exclusion of associated malignancy. PMID:25938089

    Introduction Lipoma arborescens is a rare condition of the synovial lining. It is particularly uncommon in the bicipitoradial bursae of the elbow. Case Report A 68-year-old woman presented with a 5-month history of anterior elbow pain and swelling causing discomfort. Radiography demonstrated reactive changes of radial tuberosity and magnetic resonance imaging confirmed lipoma arborescens of the bicipitoradial bursa with distal biceps tendinopathy. A bicipital bursa bursectomy and lipoma excision was performed. Gross pathology and histology was consistent with lipoma arborescens. Three months postoperatively, our patient had full range of motion and good strength. Conclusions To our knowledge, this is the first published case report of lipoma arborescens affecting the elbow. Recognising the differential diagnoses of anterior elbow pain and the characteristic imaging is essential for accurate diagnosis. PMID:27241604

    The present study entailed conducting a content analysis of 1,434 ads/profiles posted on one of the most popular "Men who have Sex with Men" (MSM) websites that specifically fosters unprotected sex. Ads/profiles were selected randomly based on the American ZIP code of residence (n = 1,316), with a randomly-drawn oversampling of profiles of men who self-identified as heterosexual or "curious" rather than gay or bisexual (n = 118). Data were collected between September 2006 and September 2007. The purpose of the present paper is to examine the conjoint effects of self-identified sexual orientation and preference for having/not having sex while high, on men's sought-after sexual risk. Analytical comparisons of the four groups showed that, on most measures, the combination of sexual orientation and drug use preference during sex differentiated the men. Generally speaking, gay/bisexual men who advertised online for partners with whom they could have sex while high expressed the greatest interest in risky sexual behaviors (e.g., felching, unprotected oral sex, unprotected anal sex) and various risk-related preferences (e.g., multiple partner sex, anonymous sex, eroticizing ejaculatory fluids). This is especially true when they are compared to their heterosexual/"curious" counterparts whose online profiles were not as likely to indicate a desire for having sex while high.

    During development, the exposure to testosterone, and its conversion to estradiol by an enzyme complex termed aromatase, appears to be essential in adult male rats for the expression of typical male sexual behavior and female-sex preference. Some hypothalamic areas are the supposed neural bases of sexual preference/orientation; for example, male-oriented rams have a reduced volume of the sexually dimorphic nucleus (oSDN), while in homosexual men this nucleus does not differ from that of heterosexual men. In contrast, homosexual men showed a larger number of vasopressinergic cells in the suprachiasmatic nucleus (SCN). Interestingly, male rats perinatally treated with an aromatase inhibitor, 1,4,6-androstatriene-3,17-dione (ATD), also showed bisexual preference and an increased number of vasopressinergic neurons in the SCN. However, this steroidal aromatase inhibitor has affinity for all three steroid receptors. Recently, we reported that the prenatal administration of the selective aromatase inhibitor, letrozole, produced a subpopulation of males with same-sex preference. The aim of this study was to compare the volume and number of cells of the SDN and SCN (the latter nucleus was immunohistochemically stained for vasopressin) between males treated with letrozole with same-sex preference, males treated with letrozole with female preference and control males with female preference. Results showed that all males prenatally treated with letrozole have a reduced volume and estimated cell number in the SDN and SCN, independent of their partner preference. These results indicate that the changes in these brain areas are not related to sexual preference, but rather to the effects of letrozole. The divergent results may be explained by species differences as well as by the critical windows during which the aromatase inhibitor was administered.

    A disintegrin and metalloproteinases (ADAMs) constitute a protein family essential for extracellular signaling and regulation of cell adhesion. Catalytic activity of ADAMs and their predicted potential for Src-homology 3 (SH3) domain binding show a strong correlation. Here we present a comprehensive characterization of SH3 binding capacity and preferences of the catalytically active ADAMs 8, 9, 10, 12, 15, 17, and 19. Our results revealed several novel interactions, and also confirmed many previously reported ones. Many of the identified SH3 interaction partners were shared by several ADAMs, whereas some were ADAM-specific. Most of the ADAM-interacting SH3 proteins were adapter proteins or kinases, typically associated with sorting and endocytosis. Novel SH3 interactions revealed in this study include TOCA1 and CIP4 as preferred partners of ADAM8, and RIMBP1 as a partner of ADAM19. Our results suggest that common as well as distinct mechanisms are involved in regulation and execution of ADAM signaling, and provide a useful framework for addressing the pathways that connect ADAMs to normal and aberrant cell behavior.

    Height is an important concern in human mate choices. Prior research indicates that people who live in areas with abundant resources differ from those who live in areas with scarce resources regarding height preferences. Based on a health-maximizing principle, we propose a resource availability account for such differences. Compared with women's height preferences, men's height preferences are hypothesized to be more dependent on either financial or caloric resource availability. Specifically, taller females would be more preferred by males who are poor in resources than those who are rich in resources. Results from three studies supported these hypotheses. In Study 1, men from remote areas of China who had lower family income preferred taller women more than those from eastern China who had higher family income. In Study 2, men who were financially dissatisfied preferred taller women more than those who were financially satisfied. In Study 3, men with low caloric status preferred taller women more than men with high caloric status. In addition, women's height preferences in Studies 1, 2 and 3 were less determined by resource availability. These findings suggest that height preferences are changeable, depending on financial or caloric status.

    Two cases of deep lipomas of the neck developed between the skeletal muscles were presented: one intermuscular and the other intramuscular. Taking into consideration the rarity of the case, the authors examined the clinical surgical aspect, paying special attention to the relationship between sonographic and computerized tomographic characteristics and the histological aspects in order to define whether the lipomatous tumors were benign or malignant. They also studied the localization of cervical lipomas, of lipoblastomas of hibernomas and of liposarcomas and defined an anatomo-clinical classification of both superficial and deep cervical lipomas.

    Mediastinal lipoma is a rare mesenchymatous fatty tumor in child. Usually asymptomatic, it can cause asphyxiation. The authors report the case of an 18 month-baby-girl referred to us by the pediatric department for asphyxiation. The chest X ray was evocative of a mediastinal tumor. A sudden cardiorespiratory failure leads us to perform thoracotomy. A fatty tumor was found compressing the heart and the left lung. It was easily extirpated. The postoperative recovery was uneventful. Light microscopy showed a lipoma. This compressive form shows the severity of the mediastinal lipoma when it reaches a large size. The literature on this rare pathology is reviewed.

    Lipomas are very common benign slow-growing soft tissue neoplasms composed of mature adipose tissue mostly diagnosed in the fifth decade of life. These tumors rarely present in the oral cavity, representing less than approximately 5% of all benign mouth tumors. They are usually less than 2cm in size and etiology remains unclear. We report a young male patient presenting with a giant lipoma in the buccal mucosa. Histopathology revealed a large area of mature fat cells consistent with conventional lipoma and an area of the mucosal lining of the lesion suggestive of morsicatio buccarum. In the present article, we emphasize the clinicopathological features and differential diagnosis of the disease.

    Background. Spindle cell lipoma (SCL) is a benign lipomatous tumour, typically occurring in the posterior neck, shoulder or upper back of elderly males. They compose of fat, CD34 positive spindle cells, and ropey collagen on a myxoid matrix. This case highlights a rare presentation of SCL and the need for pre-operative diagnosis. Case Report. A 63-year-old gentleman presented with a pre-existing left supraclavicular mass that had recently increased in size. FNA and CT Scans were performed and results discussed in the mutidisciplinary team meeting. Excisional biopsy was recommended. Radiology. CT neck showed a left supraclavicular mass of fatty density with fine internal septations. A low-grade liposarcoma could not be excluded. Histopathology. FNA was indeterminate. Histology of specimen showed bland spindle cells with no evidence of malignancy. Immuno-histochemistry showed SCL with CD34 positivity and negative staining on CDK4 and p16. Management. Excision biopsy of the mass was performed which was technically difficult as the mass invaginated around the brachial plexus. The patient recovered well post-operatively with no neurological deficits. Conclusion. Spindle cell lipoma is a rare benign tumour and a pre-operative diagnosis based on the clinical context, imaging and immuno-histochemistry is crucial to management.

    Although the removal of forehead and brow benign tumors using an endoscopic technique has proven to be valuable, the efficacy of an endoscopic excision for cheek masses is unclear. A retrospective review was performed on 8 patients with a lipoma (7) and a foreign body granuloma (1) located at the cheek region. There were 7 men and 1 woman with a mean age of 34.8 years (range, 22-54 years). All the excisional procedures were performed with an endoscope through 2 small incisions, one on the hair-bearing sideburns and the other behind the earlobe. The masses varied from 0.7 x 0.7 cm to 4.0 x 3.0 cm in size. There were no intraoperative or postoperative complications, and no recurrence was detected after a 5- to 61-month follow-up. An endoscopically assisted excision of cheek lipomas is an effective procedure and might be a good alternative to the more conventional procedures.

    Spindle cell lipoma located in the dermis is uncommon. The plexiform variant of this tumor is rare. In fact, only six cases of this variant have been described previously. We report herein a case of dermal plexiform spindle cell lipoma with prominent myxoid matrix. A 47-year-old male patient presented with a solitary, 2.2 cm-cutaneous mass in the right buttock region that had slowly increased in size for over one year. The dermal lesion was characterized by a mixture of mature adipocytes, spindle shaped cells and inconspicuous ropey collagen bundles in a mucinous background. This lesion showed a fascicular and plexiform pattern with adipocytes irregularly arranged, predominant in the depth of the lesion. Immunohistochemically, the spindle cells were positive for CD34, factor XIIIa, and vimentin, and negative for retinoblastoma protein, claudin-1, GLUT-1, epithelial membrane antigen, neurofilament protein, and Sox-10. S100 protein stained a thinned cytoplasmic rim of mature adipocytes and labeled about 25% of spindle cells in the most superficial areas. A review of the seven cases published, including the present report, revealed that there were five females and two males. Most cases located in the thigh-groin-buttock area. The age of the patients ranged from 32 to 58 years with a mean of 45.7 years. Clinical diagnosis suggested a lipomatous or neural tumor in six cases. The main differential diagnosis includes dermal intraneural plexiform neurofibroma and purely intradermal monophasic plexiform spindle cell nevus.

    2010-01-01

    This article investigates two kinds of information search strategies in the context of selecting romantic partners. Confirmatory searching occurs when people ask for more information about a romantic partner in order to validate or confirm their assessment. Balanced searches are characterized by a search for risk information for partners rated as attractive and for attractiveness information about partners rated as risky in order to attain a more complete evaluation. A factorial survey computer program randomly constructed 5 types of partner descriptions and college-age respondents evaluated nine descriptions in terms of both health risk and romantic attractiveness outcomes. The results show little evidence of balanced search strategies: for all vignette types the respondents searched for attractiveness information. Regression analysis of the search outcomes showed no difference between males and females in the desire for attractiveness or risk information, the amount of additional information desired, or the proportion of descriptions for which more information was desired. However, an attractive physical appearance did increase the amount of additional information desired and the proportion of vignettes for which more information was desired. The results were generally inconsistent with a balanced search hypothesis; a better characterization of the respondents' strategy might be “confirmatory bias.” PMID:18350465

    This study assessed the effects of short- and long-term mating contexts on preferences for body characteristics of potential relationship partners in lesbians and heterosexual women. Lesbians (n = 41) rated figure drawings and computer-generated images of women that varied in body fat, waist-to-hip ratio, and breast size; heterosexual women (n = 95) rated computer-generated images of men that varied in muscularity and body fat. Both lesbians and heterosexual women showed a shift in preferences toward more physically attractive partners for shortterm relationships. All body aspects were affected, except that heterosexual women did not show a preference shift for male body fat. The results were interpreted in terms of a mating trade-off strategy in which mate preferences are the consequence of cost/benefit analyses and suggest that preferences for physical attributes of sexual partners may be shared by members of the same sex regardless of sexual orientation.

    Oxytocin (OT) is a deeply conserved nonapeptide that acts both peripherally and centrally to modulate reproductive physiology and sociosexual behavior across divergent taxa, including humans. In vertebrates, the distribution of the oxytocin receptor (OTR) in the brain is variable within and across species, and OTR signaling is critical for a variety of species-typical social and reproductive behaviors, including affiliative and pair bonding behaviors in multiple socially monogamous lineages of fishes, birds, and mammals. Early work in prairie voles suggested that the endogenous OT system modulates mating-induced partner preference formation in females but not males; however, there is significant evidence that central OTRs may modulate pair bonding behavior in both sexes. In addition, it remains unclear how transient windows of central OTR signaling during sociosexual interaction modulate neural activity to produce enduring shifts in sociobehavioral phenotypes, including the formation of selective social bonds. Here we re-examine the role of the central OT system in partner preference formation in male prairie voles using a selective OTR antagonist delivered intracranially. We then use the same antagonist to examine how central OTRs modulate behavior and immediate early gene (Fos) expression, a metric of neuronal activation, in males during brief sociosexual interaction with a female. Our results suggest that, as in females, OTR signaling is critical for partner preference formation in males and enhances correlated activation across sensory and reward processing brain areas during sociosexual interaction. These results are consistent with the hypothesis that central OTR signaling facilitates social bond formation by coordinating activity across a pair bonding neural network. PMID:26643557

  17. Capturing the Interpersonal Implications of Evolved Preferences? Frequency of Sex Shapes Automatic, But Not Explicit, Partner Evaluations

    2016-01-01

    Sex is crucial to reproduction, and thus humans likely evolved a strong predisposition to engage in sexual intercourse. Given that meeting interpersonal preferences tends to promote positive relationship evaluations, sex within a relationship should be positively associated with relationship satisfaction. Nevertheless, prior research has been inconclusive in demonstrating such a link, with longitudinal and experimental studies showing no association between sexual frequency and relationship satisfaction. Crucially, though, all prior research has utilized explicit reports of satisfaction, which reflect deliberative processes that may override the more automatic implications of phylogenetically older evolved preferences. Accordingly, capturing the implications of sexual frequency for relationship evaluations may require implicit measurements that bypass deliberative reasoning. Consistent with this idea, one cross-sectional and one three-year study of newlywed couples revealed a positive association between sexual frequency and automatic partner evaluations but not explicit satisfaction. These findings highlight the importance of automatic measurements to understanding interpersonal relationships. (150 words) PMID:27084851

    Lipomas of the spinal cord are often a component of spinal dysraphic states. Nondysraphic intramedullary spinal cord lipomas are rare, and concomitant isolated cervical and lumbar intradural intramedullary lipomata are very rare. One patient with concomitant isolated nondysraphic cervical and lumbar spinal cord lipomata has been reported and management options discussed. A young girl presented with insidious-onset diffuse neck pain and early myelopathic signs. Conventional radiographs were normal. Magnetic resonance imaging of the whole neuraxis revealed concomitant cervical and lumbar intradural intramedullary lipoma. Subtotal resection of the lesion was performed at both levels, after which the patient improved symptomatically and was ambulant independently. Concomitant intradural lipomas at 2 different locations unassociated with a dysraphic state is very rare. Magnetic resonance imaging with fat suppression study is the investigation of choice. Adequate decompression with subtotal removal is the treatment of choice.

    Objective To determine the incidence, significance, and anatomy of spermatic cord and round ligament lipomas. Methods This was a retrospective review of 280 hernia repairs on 217 patients performed by a single surgeon (M.E.A.) from January 1996 to January 2000. The incidence of cord lipoma and relationship to inguinal hernia were evaluated. Further, when identified at the time of laparoscopic preperitoneal hernia repair, the anatomy of the lipomas was studied both at the time of surgery and again on review of videotapes. Results One hundred ninety-nine laparoscopic and 81 open inguinal hernia repairs were performed on 192 male patients and 25 female patients. Sixty-three lipomas of the cord were identified for an incidence of 22.5%. Overall, 18 cord lipomas were found in groins without hernias, and these were identified before surgery in 10 (2 by physical examination, 7 by groin ultrasound, and 1 by magnetic resonance imaging). The remaining nine were misidentified as a hernia before surgery. Fourteen of these patients presented with groin pain and four were asymptomatic. Forty-five lipomas were associated with hernias and were characterized as a hernia by examination in 43 instances. There were 32 (51%) cord lipomas associated with indirect hernias, 11 (17%) with direct hernias, and 1 each with pantaloon and femoral hernias. Nine lipomas were found in women, seven presenting with groin pain and six found without an associated peritoneal defect. Two patients presented with symptomatic cord lipomas after laparoscopic hernia repair. A lipoma of the cord is herniated fat that appears to originate from the retroperitoneal fat outside and posterior to the internal spermatic fascia and protrudes through the internal ring lateral to the cord. They are generally not visible by transperitoneal inspection unless manually reduced. Conclusions Lipomas of the cord and round ligament occur with a significant incidence. They can cause hernia-type symptoms in the absence of a true

    Lipomas are the most common subcutaneous soft-tissue tumors. These are benign tumors originating from the adipocytes. They may be located in any part of the body and can be confused clinically with other soft tissue masses. They infrequently occur in the head and neck region. We present a case of solitary lipoma arising in the neck region that was reported to our division of oral and maxillofacial surgery. PMID:25767361

    Lipoma arborescens, described as lipomatous infiltration and distention of synovial villi resulting in a frond-like appearance, most frequently affects the suprapatellar recess of the knee. While there have been reports of this entity involving the upper extremity joints, bursa, and tendon sheaths, we present the first reported case of lipoma arborescens isolated to the biceps tendon sheath. We describe imaging and histologic findings with clinical correlation.

    Most previous studies of individual differences in women's and men's preferences for sexually dimorphic physical characteristics have focused on the importance of mating-related factors for judgments of opposite-sex individuals. Although studies have suggested that people may show stronger preferences for feminine individuals of both sexes under conditions where social support may be at a premium (e.g., during phases of the menstrual cycle where raised progesterone prepares women's bodies for pregnancy), these studies have not demonstrated that perceptions of available social support directly influence femininity preferences. Here we found that (1) women and men randomly allocated to low social support priming conditions demonstrated stronger preferences for feminine shape cues in own- and opposite-sex faces than did individuals randomly allocated to high social support priming conditions and (2) that people perceived men and women displaying feminine characteristics as more likely to provide them with high-quality social support than those displaying relatively masculine characteristics. Together, these findings suggest that social support influences face preferences directly, potentially implicating facultative responses whereby people increase their preferences for pro-social individuals under conditions of low social support.

    Background Lanreotide Autogel® is supplied in prefilled syringes. Therefore, it is possible for patients with neuroendocrine tumors to use self-/partner-administered injections. The primary objective of this study was to assess the proportion of patients preferring self/partner injections over injections administered by health care professionals, and to describe the impact of self/partner administration on efficacy, safety, and costs. Methods Of 62 eligible patients, 26 (42%) patients with neuroendocrine tumors treated with a stable dose of lanreotide Autogel 90 mg or 120 mg every 4 weeks agreed to participate in this Phase IV, international, open-label, crossover study, conducted at hospitals in Sweden, Norway, and Denmark. Patients were randomized to two blocks, starting with administration of lanreotide Autogel by either self/partner or a health care professional. Preference for injections administered by self/partner or health care professionals was measured, as well as efficacy, safety, and health care resource utilization (both direct and indirect costs). Results Of 25 evaluable patients, 22 (88%) preferred self/partner injections, mainly because they experienced increased independence. Based on all patients asked to participate (n = 62), 35% preferred self/partner injections on a regular basis. There was no difference in efficacy or safety between the two administration blocks. Conclusion Many patients with neuroendocrine tumors prefer self/partner injection of lanreotide Autogel, and are able to self/partner inject without any impact on efficacy or safety. This administration method seems to provide a good alternative for suitable patients to increase patient independence and reduce the number of clinic visits. PMID:23118529

    The present study investigated 1) the importance of the aromatization process during the perinatal period for the development of the sexually dimorphic nucleus in the preoptic area of the hypothalamus (SDN-POA) of male rats, and 2) the relationship between SDN-POA volume and parameters of masculinization in male rats that were treated perinatally with the aromatase-inhibitor ATD. Males were treated with ATD either prenatally or pre- and neonatally, or with the vehicle. Masculine sexual behavior and partner preference were investigated in adulthood. Thereafter, animals were sacrificed and SDN-POA volume was measured. The SDN-POA volume was reduced in both the prenatally and the pre- and neonatally treated group, with a larger reduction in the latter than in the former group. Combined pre- and neonatal ATD treatment resulted in reduced frequency of mounts, intromissions, and ejaculations, as well as a reduced preference for a female over a male. The SDN-POA size was significantly and positively correlated with frequency of masculine sexual behavior, as well as preference for a female over a male.

  10. Strong contributions from vertical triads to helix-partner preferences in parallel coiled coils.

    2012-09-26

    Pairing preferences in heterodimeric coiled coils are determined by complementarities among side chains that pack against one another at the helix-helix interface. However, relationships between dimer stability and interfacial residue identity are not fully understood. In the context of the "knobs-into-holes" (KIH) packing pattern, one can identify two classes of interactions between side chains from different helices: "lateral", in which a line connecting the adjacent side chains is perpendicular to the helix axes, and "vertical", in which the connecting line is parallel to the helix axes. We have previously analyzed vertical interactions in antiparallel coiled coils and found that one type of triad constellation (a'-a-a') exerts a strong effect on pairing preferences, while the other type of triad (d'-d-d') has relatively little impact on pairing tendencies. Here, we ask whether vertical interactions (d'-a-d') influence pairing in parallel coiled-coil dimers. Our results indicate that vertical interactions can exert a substantial impact on pairing specificity, and that the influence of the d'-a-d' triad depends on the lateral a' contact within the local KIH motif. Structure-informed bioinformatic analyses of protein sequences reveal trends consistent with the thermodynamic data derived from our experimental model system in suggesting that heterotriads involving Leu and Ile are preferred over homotriads involving Leu and Ile.

    We sought to identify what abused Peruvian women want or need as intervention strategies. We conducted five focus groups with thirty women with prior or current experience with intimate partner violence. Participants noted that abused women need compassionate support, professional counseling, informational and practical (e.g., work skills training, employment, shelter, financial support) interventions. We propose a two-tiered intervention strategy that includes community support groups and individual professional counseling. This strategy is intended to offer broad coverage, meeting the needs of large groups of women who experience abuse, while providing specialized counseling for those requiring intensive support. Respect for each woman’s autonomy in the decision-making process is a priority. Interventions targeted towards women and men should address structural factors that contribute to violence against women. PMID:25741931

    Colorectal lipomas are the second most common benign tumors of the colon. These masses are typically incidental findings with over 94% being asymptomatic. Symptoms-classically abdominal pain, bleeding per rectum and alterations in bowel habits-may arise when lipomas become larger than 2 cm in size. Colonic lipomas are most often noted incidentally by colonoscopy. They may also be identified by abdominal imaging such as computed tomography or magnetic resonance imaging. We report a case of a sixty-one years old male who presented to our emergency room with a 6.7 cm × 6.3 cm soft tissue mucosal mass protruding transanally. The patient was stable with a benign abdominal examination. The mass was initially thought to be a rectal prolapse; however, a limited digital rectal exam was able to identify this as distinct from the anal canal. Since the mass was irreducible, it was elected to be resected under anesthesia. At surgery, manipulation of the mass identified that the lesion was pedunculated with a long and thickened stalk. A laparoscopic linear cutting stapler was used to resect the mass at its stalk. Pathology showed a polypoid submucosal lipoma of the colon with overlying ulceration and necrosis. We report this case to highlight this rare but possible presentation of colonic lipomas; an incarcerated, trans-anal mass with features suggesting rectal prolapse. Trans-anal resection is simple and effective treatment.

    Whether and how primates are able to maintain long-term affiliative relationships is still under debate. Emotional bookkeeping (EB), the partner-specific accumulation of emotional responses to earlier interactions, is a candidate mechanism that does not require high cognitive abilities. EB is difficult to study in real animals, due to the complexity of primate social life. Therefore, we developed an agent-based model based on macaque behavior, the EMO-model, that implements arousal and two emotional dimensions, anxiety-FEAR and satisfaction-LIKE, which regulate social behavior. To implement EB, model individuals assign dynamic LIKE attitudes towards their group members, integrating partner-specific emotional responses to earlier received grooming episodes. Two key parameters in the model were varied to explore their effects on long-term affiliative relationships: (1) the timeframe over which earlier affiliation is accumulated into the LIKE attitudes; and (2) the degree of partner selectivity. EB over short and long timeframes gave rise to low variation in LIKE attitudes, and grooming partner preferences were only maintained over one to two months. Only EB over intermediate-term timeframes resulted in enough variation in LIKE attitudes, which, in combination with high partner selectivity, enables individuals to differentiate between regular and incidental grooming partners. These specific settings resulted in a strong feedback between differentiated LIKE attitudes and the distribution of grooming, giving rise to strongly reciprocated partner preferences that could be maintained for longer periods, occasionally up to one or two years. Moreover, at these settings the individual's internal, socio-emotional memory of earlier affiliative episodes (LIKE attitudes) corresponded best to observable behavior (grooming partner preferences). In sum, our model suggests that intermediate-term LIKE dynamics and high partner selectivity seem most plausible for primates relying on

    Intrascrotal lipomas are benign diseases that originate from adipose tissue inside the scrotal sac or constituting the scrotal wall itself. Paratesticular spermatic cord lipomas are a rare type of intrascrotal lipomas. A 78 years old patient in good health comes to our attention for massive tense-elastic swelling of left hemiscrotum appeared about 3 years ago and slowly increasing. Ultrasound evaluation of the intrascrotal mass showed inhomogeneous images mainly hyperechoic, not infiltrating the ipsilateral testis and scrotal wall. The ultrasonography found a lipomatous lesion with benign characteristics and a surgical excision has been performed. The lipomatous mass removed presented a size equal to 25 cm x 14 cm x 11 cm and a weight of about 490 gr. The microscopic examination of the tissue showed only the presence of mature adipocytes in the absence of cellular atypia, of other cellular types and of vascular abnormalities.

    Injection lipolysis or lipodissolve is the practice of injecting phosphatidyl choline/ sodium deoxycholate (PDC/DC) compounds in the subcutaneous fat. Though this practice is being used extensively for nonsurgical contouring of body and dissolving localized collections of excess fat, it's use as a treatment modality for lipomas needs further evaluation. We present a case where this technique was used for treating a lipoma, with no recurrence after 9 months of follow up. Injection lipolysis as a treatment modality for lipomas needs to be evaluated for safety and efficacy in trials on larger population. This could prove to be a very valuable adjunct to the current practice of excision, if done by a trained person in a properly selected patient. Also the side effects and the controversies regarding this procedure have been discussed in detail in the present paper.

    Gastric lipomas are rare tumors, accounting for 2%-3% of all benign gastric tumors. They are of submucosal or extremely rare subserosal origin. Although most gastric lipomas are usually detected incidentally, they can cause abdominal pain, dyspeptic disorders, obstruction, invagination, and hemorrhages. Subserosal gastric lipomas are rarely symptomatic. There is no report on treatment of subserosal gastric lipomas in the English literature. We present a case of a 50-year-old male with symptomatic subserosal gastric lipoma which was successfully managed with removal, enucleation of lipoma, explorative gastrotomy and edge resection for histology check of gastric wall. The incidence of gastric lipoma, advanced diagnostic possibilities and their role in treatment modalities are discussed.

    Summary Lipoma is a benign tumour of mesenchymal origin with a very rare occurrence in the upper aero-digestive tract. To date, approximately 100 cases have been described in the literature. This lesion has a slow growth and, therefore, can present with various symptoms due to the mass effect with obstruction and compression on neighbouring structures, including dysphagia for liquid and solid food, dyspnoea and hoarseness. For a precise pre-operative diagnosis, indirect or direct laryngoscopy (flexible fibre-optic laryngoscopy) can be employed or, if necessary, also imaging techniques such as computed tomography scan and magnetic resonance imaging scan. These offer more useful information for better treatment planning. Surgery is the treatment of choice and includes endoscopic techniques and an external surgical approach (cervicotomy). It is very important to completely remove these benign neoplasms in order to avoid local recurrence. The present report refering to a case of laryngeal lipoma removed through an external surgical approach, aims to demonstrate that the choice of an external surgical approach is required for complete surgical removal of a large lipoma in order to prevent any possible recurrence. Furthermore, it is useful to keep in mind the possibility of recurrence of lipomas after long free intervals; therefore, it is mandatory to observe these patients at long-term follow-up.

    Spindle cell lipoma is a relatively rare adipocytic neoplasm, which usually occurs in the posterior neck, shoulder or upper back of male patients aged 45-65 years. We report here an unusual coexistence of ordinary and spindle cell lipoma. The patient presented with a painless mass in the area of the right scapula. Imaging was suggestive of a lipomatous mass, possibly liposarcoma. Histological examination revealed the concurrent existence of an intramuscular spindle cell lipoma and an ordinary lipoma. In the literature there are only fourteen cases of intramuscular spindle cell lipoma and only in four cases there was a coexisting mature lipoma. As exclusion of malignancy remains clinicians main concern,diagnosis and treatment of deep seated lipomatous tumors remains challenging.

    A 52-year-old female was referred because of melaena. After initital work-up, including gastroduodenoscopy, endosonography and CT scan, a duodenotomy was performed. Definite diagnosis was a duodenal lipoma based on histological findings. Lipomas of the gastrointestinal tract are rare. Only 4% occur in the duodenum. The peak incidence is around the 5th and 7th decade of life, with a slight female preponderance. Gastrointestinal lipomas are usually asymptomatic, but can present with mild to severe gastrointestinal bleeding, intussusceptions, abdominal pain, constipation and diarrhea. Clinical, endoscopical, surgical, and radiological features are described in this case of duodenal lipoma.

    Lipoma is the commonest benign tumour occurring at any anatomical site where fat is present, but occurrence in the oral cavity is rare. Tongue which is totally devoid of fat cells is a rare site for lipoma. This is one such rare case of the universal tumour, presenting at the lateral margin of the tongue, for which complete tumour excision was done. Macroscopically the mass had a hard consistency and measured 3.0×2.0 cm. From microscopic examination, diagnosis of lipoma was made. Recurrence of tongue lipoma is rare. PMID:23370950

  11. ErbB-2, the preferred heterodimerization partner of all ErbB receptors, is a mediator of lateral signaling.

    1997-01-01

    We have analyzed ErbB receptor interplay induced by the epidermal growth factor (EGF)-related peptides in cell lines naturally expressing the four ErbB receptors. Down-regulation of cell surface ErbB-1 or ErbB-2 by intracellular expression of specific antibodies has allowed us to delineate the role of these receptors during signaling elicited by: EGF and heparin binding EGF (HB-EGF), ligands of ErbB-1; betacellulin (BTC), a ligand of ErbB-1 and ErbB-4; and neu differentiation factor (NDF), a ligand of ErbB-3 and ErbB-4. Ligand-induced ErbB receptor heterodimerization follows a strict hierarchy and ErbB-2 is the preferred heterodimerization partner of all ErbB proteins. NDF-activated ErbB-3 or ErbB-4 heterodimerize with ErbB-1 only when no ErbB-2 is available. If all ErbB receptors are present, NDF receptors preferentially dimerize with ErbB-2. Furthermore, EGF- and BTC-induced activation of ErbB-3 is impaired in the absence of ErbB-2, suggesting that ErbB-2 has a role in the lateral transmission of signals between other ErbB receptors. Finally, ErbB-1 activated by all EGF-related peptides (EGF, HB-EGF, BTC and NDF) couples to SHC, whereas only ErbB-1 activated by its own ligands associates with and phosphorylates Cbl. These results provide the first biochemical evidence that a given ErbB receptor has distinct signaling properties depending on its dimerization. PMID:9130710

  13. Is the distant relationship of fathers and homosexual sons related to the sons' erotic preference for male partners, or to the sons' atypical gender identity, or to both?

    Study 1 compared the retrospectively reported father-son relationships of four groups of adult males: (a) Gynephiles (males who erotically prefer physically mature females), (b) androphiles (who prefer physically mature males), (c) a combined group of heterosexual pedophiles and pedohebephiles (the latter being attracted to pubescent as well as prepubescent females), and (d) a combined group of homosexual pedophiles and pedohebephiles (the latter attracted to pubescent as well as prepubescent males). The gynephiles were paid volunteers; the latter three groups were patients. The androphiles, the only group among those compared known to exhibit a measurably greater degree of cross gender identity in childhood, were also the only group to report significantly poorer father-son relations. The homosexual pedo/pedohebephiles, who also prefer male partners but who exhibit typical male gender identity in childhood, did not differ in father-son relations from the gynephiles or the heterosexual pedo/pedohebephiles. Study 2 showed that, within a sample of nonpatient volunteer androphiles, those individuals who reported the greatest degree of cross gender behavior in childhood also tended to report the worst relationships with their fathers. This correlation was replicated within a sample of androphilic patients in Study 3. The consistent pattern of results obtained from these three studies suggests that the emotionally distant relationships of fathers and androphilic sons relate to the sons' atypical childhood gender identity (or observable gender role behavior) rather than to the sons' erotic preference for male partners per se.

    Esophageal lipoma is an uncommon benign tumor of the esophagus and accounts for only 0.4% of all benign neoplasms of the gastrointestinal system. The majority of these are located in the cervical part; only very few are located in the lower third of the esophagus. We discuss the case of a 37-year-old female who presented with dysphagia and an esophageal lipoma located in the lower third of the esophagus. The patient underwent right mini-thoracotomy and enucleation of lipoma. Histopathologic examination revealed adipose tissue with a collection of matured adipose tissue. We present the case because of the atypical localization of an esophageal lipoma and development of a diverticulum, which was caused by the lipoma and required an additional surgical procedure.

    Pleomorphic lipoma is a rare, benign, soft tissue neoplasm that characteristically occurs as a subcutaneous mass in the posterior neck or upper back and rarely in the tonsillar fossa and oral cavity. Histologically, pleomorphic lipoma contains varying amounts of mature fat, areas of spindle and pleomorphic cells, floret giant cells and thick rope - like collagen in a myxoid stroma. Pleomorphic lipoma with scanty fatty elements is called the fat free variant of pleomorphic lipoma. The combination of meagre amount of fat and presence of pleomorphic elements gives a pseudosarcomatous picture under the microscope leading to misdiagnosis and over treatment. Here, we report a case of fat free pleomorphic lipoma, first of its kind in the oral cavity and discuss the diagnostic features and differential diagnosis.

    Intracranial lipomas are rare congenital malformations. The most common type of intracranial lipoma is the interhemispheric lipoma, which is frequently associated with callosal anomalies such as hypogenesis or agenesis of the corpus callosum. In contrast, interhemispheric lipomas are less often accompanied with malformations of cortical development (MCD). We report magnetic resonance imaging findings of three infants with an interhemispheric lipoma, associated with a callosal anomaly, and MCD: two infants with nodular interhemispheric lipoma, agenesis of the corpus callosum, and polymicrogyria, and one infant with interhemispheric curvilinear lipoma, hypoplasia of the corpus callosum, and heterotopias. An association was suggested regarding the occurrence of these malformations.

    We studied a series of spindle cell lipomas arising in atypical sites and showing unusual morphologic features (which we called atypical spindle cell lipoma) to assess if these lesions have the same chromosomal alterations as classical spindle cell lipoma but different from those found in atypical lipomatous tumor/well-differentiated liposarcoma. We investigated alterations of different genes in the 13q14 region and the amplification status of the MDM2 and CDK4 genes at 12q14-15 by multiplex ligation-dependent probe amplification (MLPA) and fluorescence in situ hybridization (FISH) analysis. In the atypical spindle cell lipomas, MLPA revealed deletions in the two nearest flanking genes of RB1 (ITM2B and RCBTB2) and in multiple important exons of RB1. In contrast, in classical spindle cell lipomas, a less complex loss of RB1 exons was found but no deletion of ITM2B and RCBTB2. Moreover, MLPA identified a deletion of the DLEU1 gene, a finding which has not been reported earlier. We propose an immunohistochemical panel for lipomatous tumors which comprises of MDM2, CDK4, p16, Rb, which we have found useful in discriminating between atypical or classical spindle cell lipomas and other adipocytic neoplasms, especially atypical lipomatous tumor/well-differentiated liposarcoma. Our findings strengthen the link between atypical spindle cell lipoma and classical spindle cell lipoma, and differentiate them from atypical lipomatous tumor/well-differentiated liposarcoma.

    This study assesses whether characteristics of one's own body image influences preferences of attractiveness in a partner. The role of gender and sexual orientation is also considered. Heterosexual women (n=67), lesbian women (n=73), heterosexual men (n=61) and gay men (n=82) participated in an internet survey assessing attitudes towards the body and preferences of attractiveness in a partner. Men in particular were found to prefer attractive partners, regardless of sexual orientation. Weight/shape dissatisfaction was found to be a negative predictor for heterosexual men and women. For gay men, preferences were better explained by internalization and weight/shape dissatisfaction. No such associations were found in the lesbian group. Levels of weight/shape dissatisfaction and internalization of socio-cultural slenderness ideals influence expectations of thinness and attractiveness in a partner with this effect being modified by gender and sexual orientation.

    Intraosseous lipomas are one of the rarest bone tumors found in the body. The incidence has been reported to be <0.1% of all primary bone tumors. The differential diagnoses of an intraosseous lipoma in the calcaneus include plantar fasciitis, retrocalcaneal bursitis, gout, stress fracture, unicameral bone cyst, aneurysmal bone cyst, osteoblastoma, enchondroma, chondromyxoid fibroma, nonossifying fibroma, giant cell tumor, chondroblastoma, fibrous dysplasia, and chondrosarcoma. It has been reported that 60% to 70% of patients with an intraosseous lipoma present with symptoms. This article describes a case of a pathologic fracture secondary to a large intraosseous lipoma, the surgical treatments, and the subsequent resolution of symptoms. The purpose of our report was 3-fold: (1) to increase awareness of intraosseous lipomas and their potential to cause pathologic fractures in the calcaneus; (2) to suggest a possible treatment protocol for intraosseous lipomas in the calcaneus; and (3) to describe a rare case of an intraosseous lipoma of the calcaneus not located exclusively in the neutral triangle.

    Mesenteric lipoma is an extremely rare disease in children. Fewer than 50 cases have been reported in the literature. Diagnosis is based on clinical examination, ultrasound, and computed tomography (CT). However, only the histological study of the specimen during laparotomy or laparoscopy can confirm the diagnosis. Thus, surgery, be it by laparotomy or laparoscopic, is both a means of exploration and treatment in mesenteric lipoma. We report on a case of giant lipoma of the mesentery in a 7-year-old girl presenting paroxysmal abdominal pain with a subocclusive syndrome lasting 1 week.

    Since mycoheterotrophic plants (MHPs) completely depend on their mycorrhizal fungi for carbon, selection of fungal partners has an important role in the speciation of MHPs. However, the causes and mechanisms of mycobiont changes during speciation are not clear. We tested fungal partner shifts and changes in mycorrhizal specificity during speciation of three closely related MHPs-Gastrodia confusa (Gc), G. pubilabiata (Gp), and G. nipponica (Gn) (Orchidaceae)-and correlations between these changes and the vegetation types where each species grows. We investigated the diversity of mycobionts of the three species by sequencing nrDNA ITS, and the sequence data were subjected to test changes in fungal specificity and fungal partner shifts among the three species. Furthermore, we conducted multivariate analysis to test for differences in mycobiont communities of vegetation types where each species grows. Two saprobic Basidiomycota, Marasmiaceae and Mycenaceae, were dominant fungal partners of the three species, and Gn was simultaneously associated with the ectomycorrhizal Russulaceae and Sebacinaceae. Although mycobiont composition differed among the three species, they also sometimes shared identical fungal species. Multivariate analysis revealed that mycobiont communities of the three species in bamboo thickets differed significantly from those in other vegetation types. Fungal partner shifts are not necessarily associated with the evolution of MHPs, and fungal specificity of Gc and Gp was significantly higher than that of Gn, implying that the specificity fluctuates during speciation. Further, Gc exclusively inhabits bamboo thickets, which suggests that adaptation to particular fungi specific to bamboo thickets triggered speciation of this species. © 2016 Botanical Society of America.

    Spindle cell lipoma is a benign lipomatous tumor, which usually arises on the back of the neck, shoulder or upper back of males in the third to seventh decade of life. We report herein an unusual infiltrating intramuscular spindle cell lipoma arising in the nose of a 53-year-old man. The patient presented with a 0.5-cm 'cyst' of the nose, just above the right alar crease, which was removed. Four years later, the lesion recurred and was re-excised. Histologically, a proliferation of mature adipocytes, ropey collagen fibers and spindle cells within a myxoid stroma was present in the subcutaneous tissue and infiltrated between skeletal muscle fibers. Nine cases of intramuscular spindle cell lipoma with histological examination have previously been reported and have involved the oral cavity and muscles of the extremities. To our knowledge, this is the first report of an infiltrating intramuscular spindle cell lipoma arising on the face.

    The present case illustrates a lipoma as an unusual cause of heel pain. A 64-year-old female ballroom dancer presented with 8 months of pain that was unresponsive to previous treatment of plantar fasciitis. Magnetic resonance imaging revealed a heel lipoma. Her pain was fully resolved after surgical excision. Soft tissue tumors should be included in the differential diagnosis of heel pain, especially when symptoms and treatment response do not follow the typical course of plantar fasciitis.

    Pseudoangiomatous pleomorphic/spindle cell lipoma is a rare subtype of pleomorphic/spindle cell lipoma. Only approximately 20 such tumors have been described. Genetic information on pseudoangiomatous pleomorphic/spindle cell lipoma is restricted to a single case in which deletion of the forkhead box O1 (FOXO1) gene was found, using fluorescence in situ hybridization (FISH). G-banding and FISH analyses were performed on a pseudoangiomatous pleomorphic/spindle cell lipoma. G-banding of tumor cells showed complex karyotypic changes including loss of chromosome 13. FISH analysis revealed that the deleted region contained the RB1 gene (13q14.2) and the part of chromosome arm 13q (q14.2-q14.3) in which spans the TRIM13 gene, the two non-coding RNA genes, DLEU1 and DLEU2, and the genetic markers RH44686 and D13S25. Several acquired genomic aberrations were found in the tumor. Among them was loss of chromosome 13 material. Results confirm the (cyto)genetic similarity between pseudoangiomatous pleomorphic/spindle cell lipoma and spindle cell lipomas.

    2014-03-14

    Despite attention to the sexual behaviors of non-gay-identified (NGI) men who have same-sex encounters, virtually no research has focused on issues of partner desirability and selection. Limited evidence suggests that a subgroup of men who have sex with men (MSM) advertise online for sexual encounters with NGI men. Exchange theory provided a framework to investigate this seeking of NGI men, based on the content of Internet personal advertisements for same-sex encounters. Researchers analyzed 282 ads posted to an online bulletin board. Ads by men who explicitly desired encounters with NGI men were compared with those by men who did not indicate this preference in potential partners. Multivariate analyses revealed that NGI-seeking men had significantly increased odds of identifying as discreet (Adjusted odds ratio [AOR] = 2.82), seeking a discreet encounter (AOR = 4.68), seeking a masculine partner (AOR = 2.18), being willing to host (AOR = 2.77), as well as seeking oral-receptive sex (AOR = 2.69), unprotected oral sex (AOR = 6.76), and anal-receptive sex (AOR = 2.18). Further, NGI-seeking ads were more likely to not mention condom use or safer sex practices (AOR = 4.13) and were less likely to indicate a desire for oral-insertive sex (AOR = 0.34) and rimming (AOR = 0.21). Findings suggest that some men may deliberately present themselves in ways that they perceive as being attractive to NGI men, and have research implications for NGI MSM, their partners, and the risk outcomes of these online ads.

    Chondroid lipoma, a rare benign adipose tissue tumor, may histologically resemble myxoid liposarcoma or extraskeletal myxoid chondrosarcoma, but is genetically distinct. In the current study, an identical reciprocal translocation, t(11;16)(q13;p13) was identified in three chondroid lipomas, a finding consistent with previous isolated reports. A fluorescence in situ hybridization (FISH)-based positional cloning strategy using a series of bacterial artificial chromosome (BAC) probe combinations designed to narrow the 16p13 breakpoint revealed MKL2 as the candidate gene. Subsequent 5′ RACE studies demonstrated C11orf95 as the MKL2 fusion gene partner. MKL/myocardin-like 2 (MKL2) encodes myocardin-related transcription factor B (MRTF-B) in a megakaryoblastic leukemia gene family, and C11orf95 (chromosome 11 open reading frame 95) is a hypothetical protein. Sequencing analysis of RT-PCR generated transcripts from all three chondroid lipomas defined the fusion as occurring between exons 5 and 9 of C11orf95 and MKL2, respectively. Dual-color breakpoint spanning probe sets custom-designed for recognition of the translocation event in interphase cells confirmed the anticipated rearrangements of the C11orf95 and MKL2 loci in all cases. The FISH and RT-PCR assays developed in this study can serve as diagnostic adjuncts for identification of this novel C11orf95-MKL2 fusion oncogene in chondroid lipoma. PMID:20607705

    The New York City Department of Health Disease Intervention Specialists (DIS) routinely contact newly HIV-diagnosed persons via telephone calls and in-person meetings to conduct partner services (PS) interviews in order to elicit the names and contact information of the HIV-exposed partners for notification and HIV-testing, and to assist clients with linkage to care. From October 2013 to December 2015, we offered PS interviews conducted via video-call alongside voice-call and in-person modes in a selected geographic area of NYC. PS interviews were conducted according to the clients' preferred mode (in-person, voice- or video-call) and location (health care facility, clients' residences, or other NYC locations). At the conclusion of the PS interviews, DIS elicited responses from persons interviewed via video-call on their perception, satisfaction and personal experiences using video-call for public health and personal purposes. Acceptance and satisfaction with PS interviews via video-call were high among clients aged <30 years, men who have sex with men, or with education above high school; while PS yields were similar across modes. These results provide evidence of the potential effectiveness of video-call interviews for specific populations.

    2009-02-01

    Females of the fighting fish Betta splendens have been shown to associate with other B. splendens females in a manner reminiscent of shoaling behavior. Since body coloration varies dramatically in this species, and since body coloration has been shown to affect shoalmate choice in other species of fish, we examined the influence of body coloration on association preferences in female B. splendens. In dichotomous choice tests, B. splendens females spent more time swimming near groups of females (regardless of coloration) than swimming near an empty chamber, and chose to swim near fish of similar coloration to their own when choosing between two distinctly colored groups of females. When examining the interplay between body coloration and group size, focal fish spent more time swimming near larger groups (N=5) of similarly colored fish than swimming near an individual female of similar coloration. However, focal fish showed no preference when presented with an individual female of similar coloration and a larger group of females of dissimilar coloration. These results suggest that association choices in B. splendens females are strongly affected by both body coloration and by group size.

    Episacral lipoma is a small, tender subcutaneous nodule primarily occurring over the posterior iliac crest. Episacral lipoma is a significant and treatable cause of acute and chronic low back pain. Episacral lipoma occurs as a result of tears in the thoracodorsal fascia and subsequent herniation of a portion of the underlying dorsal fat pad through the tear. This clinical entity is common, and recognition is simple. The presence of a painful nodule with disappearance of pain after injection with anaesthetic, is diagnostic. Medication and physical therapy may not be effective. Local injection of the nodule with a solution of anaesthetic and steroid is effective in treating the episacral lipoma. Here we describe 2 patients with painful nodules over the posterior iliac crest. One patient complained of severe lower back pain radiating to the left lower extremity and this patient subsequently underwent disc operation. The other patient had been treated for greater trochanteric pain syndrome. In both patients, symptoms appeared to be relieved by local injection of anaesthetic and steroid. Episacral lipoma should be considered during diagnostic workup and in differential diagnosis of acute and chronic low back pain.

    This study experimentally examines the effects of participant sex, perpetrator sex, and severity of violence on perceptions of intimate partner violence (IPV) seriousness, sympathy toward the victim, and punishment preferences for the perpetrator. Participants (N = 449) were randomly assigned to a condition, exposed to a composite news story, and then completed a survey. Ratings of seriousness of IPV for stories with male perpetrators were significantly higher than ratings of seriousness for stories with female perpetrators. Men had significantly higher sympathy for female victims in any condition than for male victims in the weak or strong severity of violence conditions. Men's sympathy for male victims in the fatal severity of violence condition did not differ from their sympathy for female victims. Women had the least sympathy for female victims in the weak severity condition and men in the weak or strong severity conditions. Women reported significantly higher sympathy for female victims in the strong and fatal severity of violence conditions. Women's ratings of sympathy for male victims in the fatal severity of violence condition were statistically indistinguishable from any other group. Participants reported stronger punishment preferences for male perpetrators and this effect was magnified among men. Theoretical implications are presented with attention provided to practical considerations about support for public health services.

    The presence of tattoos on the skin of people of all ages is on the rise. On occasion, the tattoo is in close proximity to an area which has to undergo a surgical operation, therefore why not using the tattoo itself to cover the cicatrix? The case we treated was that of a 39 year old female who, for a couple of years, had a large lipoma on her right shoulder which she never treated because it was beneath a large tattoo. During the surgical treatment of the lipoma, we followed the exact lines of the tattoo itself thus obtaining precise access for lipoma removal which minimized visible post operative cicatrix while maintaining the original tattoo design. No similar case was found in literature. PMID:21103075

    The authors report 4 cases of inter and intra-muscular lipoma of the shoulder and make a review of the diagnosis of this localization. All 4 cases had shoulder pain and some limitation of shoulder motion, one had hypoesthesia on the lateral side of the arm. 3 had magnetic resonance imaging (MRI) and two ultrasonography examination, three of them had a surgical resection and for one surgery was considered too aggressive and had a MRI control one year later. There was no problem for the surgical procedure and the histology confirmed the diagnosis. The last patient had a rehabilitation program and the MRI control showed lesion stability. Lipoma are rare, X-rays, ultra-sonography and CT scans are not sufficient, MRI is the best exploration to differentiate lipoma and lipo-sarcoma, but the main problem is for low grade sarcoma. Histology is the only way to make the diagnosis with the whole tumor.

  17. Successful bronchoscopic cryorecanalization in a case of endobronchial lipoma.

    2011-01-01

    Endobronchial lipomas are rare benign tumors; less than 150 cases have been reported so far. Bronchial occlusion usually leads to a misdiagnosis of asthma/COPD or malignancy. We report the case of a 67-year-old man with a history of heavy smoking (100 pack years), dyspnea on exertion, cough, and malaise who was treated for pneumonia for three weeks. Due to nonresolving atelectasis of the superior segment of the right lower lobe, a malignant endobronchial tumor was suspected. Rigid bronchoscopy with cryorecanalization led to both the definite histopathological diagnosis of endobronchial lipoma and the reopening of an endoluminal airway obstruction during one procedure.

    Colonic lipomas are benign tumors usually asymptomatic. Occasionally, they may cause symptoms such as bleeding, intussusception, obstruction, or rectal prolapse. We present a 44-year-old African-American female that presented with an 8 cm colonic lipoma protruding through the anal verge. We also reviewed all the reported cases in the English literature. The patient was treated successfully with transanal resection, which has rarely been done before for this large a tumor. Transanal resection of large benign tumors of the rectosigmoid is possible.

    A 22-year-old man was admitted with a rapidly enlarging soft mass on the left chest wall, which was diagnosed as lipoma by postoperative pathology. A chest roentgenogram revealed a defect of the fourth rib, scoliosis, dextrocardia, and diaphragmatic hernia. A computed tomographic scan showed maldevelopment of the pectoralis major and minor muscles. This is the first reported case of Poland syndrome with ipsilateral lipoma of the chest wall. Dextrocardia associated with Poland syndrome may be considered dextroposition, rather than a dextroinversion, and it may arise as a result of Poland syndrome.

  20. Differential Diagnosis of Parotid Lipoma in a Breast Ca Patient

    PubMed Central

    2017-01-01

    Lipomas are common benign tumors usually detected on the torso, neck, upper thighs, and upper arms. However, they are rarely found in the parotid gland region. Because of their rarity at this site, they are not often considered in the differential diagnosis of parotid tumors. This report describes a rare case of a lipoma in the superficial lobe of parotid gland. A 71-year-old female patient admitted to our department complaining about swelling and pain in the posterior area of the left mandibular region since one month. Her medical history included mastectomy after breast CA fifteen years ago. Clinical examination revealed a smooth-surfaced, soft, and painful mass, with well-defined margins in the left mandibular region. Differential diagnosis of metastasis, inflammatory neck swellings, and benign salivary gland tumors were considered for the patient. Advanced imaging methods such as ultrasonography and contrast tomography revealed that the lesion was a lipoma of parotid gland. A surgical intervention under general anesthesia was planned for the removal of the mass; however patient refused the surgical treatment. Patient was placed on six-month periodic recall. This article reviews the radiographic appearance and differential diagnoses of lipoma in this rare location. PMID:28255469

    Spindle cell lipomas (SCL) are circumscribed, usually s.c. tumors that typically occur on the posterior neck, shoulder, and back of middle aged men. Cytogenetically, almost all SCL are characterized by deletions of chromosome arm 13q, often in combination with loss of 16q. Deletions of 13q are seen also in approximately 15% of conventional lipomas. Through single nucleotide polymorphism (SNP) array analyses, we identified two minimal deleted regions (MDR) in 13q14 in SCL. In MDR1, four genes were located, including the tumor suppressor gene RB1. MDR1 in SCL overlapped with the MDR detected in conventional lipomas with 13q14 deletion. In MDR2 in SCL there were 34 genes and the two microRNA (miRNA) genes miR-15a and miR-16-1. Global gene expression analysis was used to study the impact of the deletions on genes mapping to the two SCL-associated MDR. Five genes (C13orf1, DHRS12, ATP7B, ALG11, and VPS36) in SCL and one gene (C13orf1) in conventional lipomas with 13q-deletions were found to be significantly underexpressed compared with control tissues. Quantitative real-time PCR showed that miR-16-1 was expressed at lower levels in SCL than in the control samples. No mutations were found at sequencing of RB1, miR-15a, and miR-16-1. Our findings further delineate the target region for the 13q deletion in SCL and conventional lipomas and show that the deletions are associated with down-regulated expression of several genes, notably C13orf1, which was the only gene to be significantly down-regulated in both tumor types.

    This case report illustrates the potential fallacy of attributing a patient's symptoms to an incidental finding. Serial imaging of small, asymptomatic cerebellopontine angle (CPA) lipomas is favored. It is imperative to accurately diagnose CPA lipoma on imaging and differentiate it from more common CPA lesions. We herein present a patient with symptoms consistent with Bell's palsy and an incidental finding of a CPA lipoma. Additionally, we performed a review of the literature for case reports of patients presenting with facial symptoms and diagnosed with a CPA lipoma.

    Lipomas are benign neoplasms arising from adipose tissue. Oral lipomas have been reported in the buccal mucosa, tongue, floor of the mouth and lips; however, the case of a lipoma occurring as an antecedent lesion to recurrent sialadenitis is hitherto unreported in the English literature. We report the case of an intraoral lipoma occurring with signs and symptoms of recurrent sialadenitis in a 15-year-old Kenyan girl of Kikuyu descent. The lipoma was antecedent leading to partial obstruction and stasis related to the right Stensen's duct culminating in recurrent sialadenitis of the ipsilateral parotid gland. Due to the slow growth, softness, diffuse nature and lack of pain, lipomas may exist below the diagnostic radar, hence, the need to have a high index of suspicion and utilize diagnostic aids as necessary. In this case magnetic resonance imaging was key in establishing the existence of the lipoma. The lipoma was excised with resolution of the recurrent sialadenitis. The purpose of this report is to present the diagnostic challenge emanating from the pressure effects of an intraoral soft tissue lipoma masquerading as recurrent sialadenitis with a view to improving on patient care through sensitization.

    Lipomas are common benign neoplasms consisting of mature fatty tissue. They are usually of roundish or ovoid shape and are situated in a single anatomical region. They most frequently occur on the back and in the extremities. Most lipomas are subcutaneous and require no imaging evaluation. When deep, large and unusual in location, MRI can identify and localise these tumours and is the best exploration to differentiate lipoma and lipo-sarcoma. We describe a case of a patient with an intramuscular lipoma of the biceps brachii.

    The painting Mona Lisa in the Louvre, Paris, by Leonardo da Vinci (1503-1506), shows skin alterations at the inner end of the left upper eyelid similar to xanthelasma, and a swelling of the dorsum of the right hand suggestive of a subcutaneous lipoma. These findings in a 25-30 year old woman, who died at the age of 37, may be indicative of essential hyperlipidemia, a strong risk factor for ischemic heart disease in middle age. As far as is known, this portrait of Mona Lisa painted in 1506 is the first evidence that xanthelasma and lipoma were prevalent in the sixteenth century, long before the first description by Addison and Gall in 1851.

    A 70-year-old woman had pain and fatigability of her left shoulder with asymmetric scapular position. The medial border of the scapula was more prominent in the left side compared to the right scapula, and scapular motion was different between sides. Magnetic resonance imaging showed a mass on the ventral surface of the scapula. Tumour resection was performed through the medial approach, and the tissue samples were found to be a lipoma with a pathological examination. Post-operatively, her pain immediately disappeared. Two years after surgery, no recurrence of the tumour had been found. Soft tissue tumours have never been reported as a cause of scapular malposition or winging. We reported a case with scapular malposition and dyskinesis caused by lipoma in the subscapularis muscle. Surgical resection successfully relieved her symptoms and improved the scapular motion. Soft tissue tumour occurring in the subscapularis muscle could possibly cause abnormal scapular position and motion. PMID:27582987

    Benign cardiac tumours are rare and cardiac lipomas account only for a small fraction among those. Most of these tumours differ in terms of clinical manifestation, diagnosis, morphology and size, and are therefore not diagnosed easily unless they become symptomatic. We report the case of a 71-year-old Caucasian woman with recurrent episodes of shortness of breath presenting with an acute exacerbation of dyspnoea and hypertensive crisis. Diagnosis of a right atrial lipoma with a coexisting patent foramen ovale was established on echocardiography and computed tomography, and the patient was evaluated for elective surgery. Comprising the entire free wall of the right atrium, the tumour was removed during open heart surgery on cardiopulmonary bypass. The right atrium and the orifices of both the superior and inferior vena cava were reconstructed with bovine pericardium. No evidence of tumour relapse was observed during successive follow-up visits. PMID:25245725

    Intravestibular lipoma (IVL) and intravestibular schwannoma (IVS) are rare tumors occupying the intravestibular space. Patients with IVL or IVS complain of hearing impairment, tinnitus or recurrent rotatory vertigo. Therefore, the clinical practitioner could misdiagnose them as sudden sensorineural hearing loss or Meniere's disease. Since delayed diagnosis and treatment could lead to more severe and refractory symptoms, clinicians should have a high index of suspicion for early diagnosis. Recent advancements in imaging diagnostic tools such as computed tomography and magnetic resonance imaging have facilitated the correct diagnosis of these intravestibular tumors without surgical removal. Presently, we report two different kinds of intravestibular tumors of lipoma and schwannoma which manifest different clinical course and treatment strategies.

    Thirteen dogs with infiltrative lipomas were treated with cobalt 60 radiation. Four of the thirteen dogs also received either whole body (n = 2) or combination local/whole body (n = 2) hyperthermia in conjunction with radiation therapy. Cytoreductive surgery was performed prior to radiation in 10 dogs, although only 3 dogs had microscopic disease at the time of radiation therapy. Dogs received a total dose of 45.6 Gy-63 Gy in 2.5-4 Gy/fraction on either a Monday/Wednesday/Friday schedule or on a daily Monday through Friday schedule. Twelve of the 13 dogs had computed tomography (CT) images acquired prior to irradiation. Survival time was determined from the time of completion of radiation therapy. Survival ranged from 6 months to 94 months, with a median (95% confidence interval) of 40 (18.5-77) months and a mean of 46.4 months. Only one dog was euthanized due to persistent signs related to the infiltrative lipoma at 6 months after the end of radiation therapy. There was no apparent difference in response based on whether or not the dogs received hyperthermia in conjunction with irradiation, although the numbers were too small to make any significant conclusions. It appears that dogs with infiltrative lipomas can benefit from external beam irradiation alone or in combination with surgery to effect long-term local tumor control.

    Gastric lipoma is a rare tumor, accounting for only 5% of gastrointestinal tract lipomas and less than 1% of all gastric tumors. Histological diagnosis is usually easy. However, the tumor may sometimes undergo significant inflammatory changes leading to a difficult differential diagnosis with well-differentiated liposarcoma. Authors report the case of a 51-year-old man, presenting with epigastralgia of recent onset. Physical exam was unremarkable. Endoscopy revealed a large, ulcerated, submucosal, and antral tumor. CT scan showed an antral mass with fat attenuation. The patient underwent a total gastrectomy. Macroscopic examination identified in the antral wall a 9-cm, well-circumscribed, nodular lesion, with a greasy cut surface. On histological examination, the tumor was composed of a mature adipocytes proliferation, showing significant variation in cell size, associated to some lipoblasts. Nuclei were sometimes large, irregular, neither with hyperchromasia nor mitosis. Diagnosis of a well-differentiated liposarcoma was suspected and molecular cytogenetic analyses showed neither MDM2 nor CDK4 gene amplification on fluorescent in situ hybridization. The diagnosis of lipoma was made. Twelve months after surgery, the patient is doing well. In conclusion, Differentiating benign from malignant fatty tumors is sometimes difficult in morphologic features. In these cases, cytogenetic procedures are the only means for an accurate diagnosis.

    The spinal extradural space is normally occupied by adipose tissue and a venous plexus, so it should be not surprising that lipomas arise and reach sufficient size to compress symptomatically the spinal cord. Nevertheless, the spinal epidural lipomas are rare and benign tumours may present as a progressive spinal cord compression syndrome. Magnetic resonance imaging is useful in demonstrating the full extent and characteristics of these lesions, the severity of cord compression and the location in the canal. Usually, the lesion is amenable to total surgical extirpation and the functional prognosis is good. Histopathologically the tumour consists of a mature adipose cells matrix intermixed with vascular endothelial channels, that is the reason why it is also named angiolipomas. A 47 year-old woman complained of dorsal and bilateral submamarian pain lasting two years and progressive loss of sensibility and weakness in her legs. Following magnetic resonance studies a posterior spinal cord compression by an extradural tumour at T3-T7 levels was observed. She was operated on and we found an extradural yellow tumour easily to dissect and it was completely removed. One year later she is asymptomatic. Spinal epidural lipoma is a benign tumour which initially presents itself with local or radicular pain accompanied by progressive spinal cord compression syndrome. The choice treatment is laminectomy and total excision. Probably, this is one of the easiest tumours to remove of the spinal canal and a source of satisfaction because a complete recovery can usually be achieved.

    2016-10-01

    Spindle cell lipoma represents a distinct clinicopathological entity and is related to cellular angiofibroma and mammary-type myofibroblastoma. Spindle cell lipomas are composed of mature lipogenic cells and a variable number of CD34-positive spindle cells that show loss of retinoblastoma protein expression. Spindle cell lipomas occasionally express S-100 protein. We studied one case of purely dermal spindle cell lipoma and four cases of classical subcutaneous spindle cell lipoma arising in one female and four male patients (age ranged from 55 to 69 years). The neoplasms arose on the nose, the chin, the neck, the forehead and retroauricular, and all lesions had been marginally or incompletely excised. The studied cases showed classical histological and immunohistochemical features of spindle cell lipoma and, in addition, strong expression of S-100 protein by spindle-shaped tumour cells. S-100-expression in spindle cell lipoma may cause problems in the differential diagnosis with neural and melanocytic neoplasms and emphasizes the plasticity of the spindle cells in spindle cell lipoma.

    Lipoma of the large intestine is rare, with a reported incidence ranging between 0.2% and 4.4%. We present a case of a giant colonic lipoma causing descending-colonic intussusception. A 54-year-old woman visited our emergency room with sudden onset of intermittent abdominal cramps. She was nauseous and had rectal blood loss for three days. Physical examination showed a tender palpable mass in the left lower abdominal quadrant. Rectal examination showed little blood on the glove. A CT scan demonstrated a clear intussusception of the descending-colonic (Fig. 1). Since the clinical presentation was that of an imminent ileus a laparotomy was performed. The intussusception was found in the descending coloni (Fig. 2), en-bloc resection with left hemicolectomy and was performed with end-to-end anastomosis. Lipomas of the gastrointestinal tract are rare conditions first described by Baurer in 1757. Lipomas in the intestinal tract are still relatively rare, however, being present in only 0.2% of a large autopsy series of 60 000 cases reported in 1955. In 90% of cases, lipoma of the colon are localized at submucous level. Submucosal lipomas are usually asymptomatic but may cause bleeding, obstruction, intussusception, or abdominal pain. Accurate preoperative diagnosis is difficult and lipoma is often mistaken for adenomatous polyp or carcinoma. Differential diagnosis includes malignancy, diverticulosis, adenomatous polyps and previous anastomosis. CT is the examination of choice. Surgical approach remains the treatment of choice for large colon lipoma.

    Mesenteric lipomas are benign tumors of mature fat cells. They are usually asymptomatic and create a clinical picture that depends on the localization and size of the lipoma. Although rare, unusually large mesenteric giant lipomas can cause partial or complete bowel obstruction. Lipomas resulting in partial bowel obstruction can present with symptoms such as intermittent abdominal pain and abdominal distention. With complete obstruction, a child can present with an acute abdomen. Treatment is the excision of the mass along with the affected portion of bowel. In this case study, a 2-year-old female presented with a bowel obstruction due to the presence of a giant mesenteric lipoma. Clinical features of 16 cases published in the English literature to date are presented. PMID:25610284

    Patient: Female, 34 Final Diagnosis: Lipoma of the large intestine Symptoms: Abdominal pain • bloating • blood in stool • constipation • lose of appetite • nausea Medication: — Clinical Procedure: — Specialty: Surgery Objective: Rare disease Background: Lipoma of the large intestine is rare, account for only 5% of all gastrointestinal tumors. Lipomas are usually asymptomatic but rarely may cause bleeding, obstruction and intussusception. We present a case of a giant colonic lipoma causing descending-colonic intussusception. Case Report: 34 yo F presented with the intermittent left lower quadrant abdominal pain for 3 weeks. The pain initially was associated with bloating and constipation and for the last several days frank blood in stool, nausea and decreased appetite. CT scan of the abdomen revealed descending colonic obstruction by a 5.3 cm colonic lipomatous mass with resultant intussusception. Patient initially underwent colonoscopy that revealed polypoid lesion at 3–40 similar to lipoma with intussusception that was reduced. Patient subsequently underwent laparoscopic segmental left colectomy for the descending colonic intussusception due to large colonic lipomatous mass. Pathology confirmed the histology of lipoma. Conclusions: Adult bowel intussusception is a rare but challenging condition to diagnose in a timely manner. Preoperative diagnosis is usually missed or delayed because of nonspecific and often subacute symptoms. Lipoma is a rare cause of the intussusception. A high index of suspicion and appropriate investigations (abdominal ultrasound, CT scan and colonoscopy) can result in prompt diagnosis. Lipoma of the large intestine is very rare. Submucosal lipomas are usually asymptomatic but may cause bleeding, obstruction, intussusception, or abdominal pain. Accurate preoperative diagnosis is difficult and lipoma is often mistaken for adenomatous polyp or carcinoma. Treatment usually requires formal resection of the involved bowel segment

    Fat necrosis of the breast is a benign non-suppurative inflammatory process of adipose tissue that most commonly occurs as the result of minor breast trauma. We present a case of a 40-years-old female with fat necrosis in a breast lipoma. She presented with an overlapping mass on the lateral quadrants. Mammography showed Well delineated radiolucent mass with peripheral “egg-shell” calcifications, that appeared an hypoechoic mass with posterior shadowing on ultrasonography. A history of accidental trauma raises the suspicion of fat necrosis. Pathology is necessary when radiological findings simulate malignancy.

    Background Lipomas are benign mesenchymal tumors composed of mature adipocytes. They are classified according to their histological pattern and their etiology remains unclear. Objectives: To present two cases and review the literature. Material and Methods A search was conducted in the Medline / PubMed and Scielo data bases of the last 10 years (2004-2014) with the keywords “ intraoral lipoma OR oral cavity lipoma”. Results 46 articles with 95 cases (56 women and 39 men) were reviewed. The average age was found to be 52.28 years (52.28 ± 18.55); and most of them occurred between the 4th and 6th decade of life. Lipomas occur mostly in the buccal mucosa (n = 36, 37.9%), followed by the tongue (n = 23, 24.2%) and other locations (n = 36, 37.9%). The most common histologic pattern was simple lipomas (n = 40, 42%), followed by fibrolipomas (n = 18, 18.9%) and other types (n = 37, 39.1%). The average tumor size was 19.77 ± 16.26mm. Conclusions Lipomas are a relatively rare finding in the oral cavity. Surgical excision is the treatment of choice and recurrence is not expected. Key words:Benign oral tumor, oral lipoma, lipoma, oral cavity. PMID:27957277

  7. Total Resection of Complex Spinal Cord Lipomas: How, Why, and When to Operate?

    2015-01-01

    This article shows the long-term advantage of total resection of complex spinal cord lipomas over partial resection and over non-surgical treatment for children with asymptomatic lipomas. The classification, embryogenesis, and technique of total resection of complex lipomas are described. The 20-year outcome of 315 patients who had total resection is measured by overall progression-free survival (PFS, Kaplan-Meier), and by subgroup Cox multivariate hazard analysis for the influence of four variables: lipoma type, symptoms, prior surgery, and post-operative cord-sac ratio. These results are compared to 116 patients who underwent partial resection, and to two published series of asymptomatic lipomas followed without surgery. The PFS after total resection for all lipomas is 88.1% over 20 years vs. 34.6% for partial resection at 10.5 years (p < 0.0001). The PFS for total resection of asymptomatic virgin lipomas rose to 98.8% vs. 60% and 67% for non-surgical treatment. Partial resection also compares poorly to non-surgical treatment for asymptomatic lipomas. Multivariate analyses show that a low cord-sac ratio is the only independent variable that predicts good outcome. Pre-operative profiling shows the ideal patient for total resection is a young child with a virgin asymptomatic lipoma, who, with a PFS of 99.2%, is essentially cured. The technique of total resection can be learned by any neurosurgeon. Its long-term protection against symptomatic recurrence is better than partial resection and conservative management. The surgery should be done at diagnosis, except for asymptomatic small infants in whom surgery should be postponed till 6 months to minimize morbidity. PMID:26345666

    Clinically, pure spermatic-cord lipoma has not been recognized as a disease entity but regarded as an incidental finding at the time of hernia repair, because it presents groin symptoms and clinical findings indistinguishable from those of inguinal hernia. We report the successful treatment of case of huge pure spermatic-cord lipoma originally misdiagnosed as inguinal hernia. The patients had tumor excision without orchiectomy. Symptoms improved without any complication. In patients with inguinal hernia symptoms, pure spermatic-cord lipoma should be recognized as a significant clinical entity, and differential diagnosis should be achieved using ultrasonography and computed tomography to avoid unnecessary hernia repair.

  9. Posterior interosseous nerve palsy caused by parosteal lipoma of proximal radius.

    1998-07-01

    Lipomas are common benign soft tissue tumors which tend to be indolent, and symptoms caused by nerve compression are unusual. However, a parosteal lipoma, occurring adjacent to the proximal radius may easily cause paralysis of the posterior interosseous nerve because of a specific anatomical relationship of these structures in that area. Two cases of parosteal lipoma of the proximal radius causing paralysis of the posterior interosseous nerve are reported. CT and MR imaging demonstrate the characteristic fatty mass around the radius and are specific in making the diagnosis. Surgical excision should be promptly performed to ensure optimal recovery from the nerve paralysis.

    Lipomas are benign neoplasms derived from adipose tissue composed of mature adipocytes. They account for almost 50% of all soft-tissue neoplasms and occur in up to 2% of the population. They usually present asymptomatically as solitary discrete mobile lumps found most commonly on the neck, upper back, proximal limbs and chest. In less than 1% of cases, they can be found in the distal extremities.We discuss the case of a 65-year-old man who presented with a 2-year history of a slowly enlarging left palm swelling, with recent-onset numbness and loss of power in the distribution of the median nerve. MRI studies showed that the 5×4×2.7 cm lipoma had a component extending into the distal aspect of the carpal tunnel, compressing the median nerve. It was successfully excised, and at follow-up the patient reported complete resolution of his symptoms. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    2011-06-01

    Benign lytic lesions of the calcaneus are rare and are usually asymptomatic. We report this case of a 55-year-old man with bilateral non-traumatic plantar heel pain, which was treated conservatively as plantar fasciitis. At three months follow-up, the patient had complete relief of symptoms in the left heel with partial relief of symptoms on the right side. However under the insistence of the patient an X-ray was taken, which revealed an expansile lytic lesion of the right calcaneus and a normal left heel. CT-scan revealed an expansile lytic lesion on the right calcaneus and an early lytic lesion in the left calcaneus. Following surgical intervention, the diagnosis was confirmed as intra-osseous lipoma and the patient was completely symptom free at two-year follow-up. Patients presenting with non-traumatic heel pain should be explained about the possible causes of heel pain, and should be offered X-ray at the first visit. In patients with X-ray showing unilateral lipoma of the calcaneus, CT scan should be offered to rule out involvement of the opposite side.

    A 78-year-old woman who had recurrent right lower abdominal pain for about 1 year underwent computed tomography (CT) because of a follow-up observation 1 year after right breast cancer surgery. CT revealed a tumor in the colon. The patient was referred to our hospital for detailed examinations. An abdominal CT showed a low-density tumor of approximately 30 mm in the ascending colon, and the CT density inside the tumor was same as that of fatty tissues. A subsequent colonoscopy showed a submucosal tumor (SMT) in the proximal ascending colon developing from the terminal ileum. A colonoscopic ultrasonography revealed that the SMT was a high-echoic mass mainly localized in the submucosal layer. Based on the findings from CT, colonoscopy, and colonoscopic ultrasonography, the SMT was diagnosed as a pedunculated lipoma originating from the terminal ileum and treated with endoscopic submucosal dissection (ESD) because of recurrent abdominal pain. The 40-mm tumor was resected en bloc without complications. ESD may be more appropriate than polypectomy and surgery for removal of small intestinal tumors, because ESD allows direct visualization of the cutting line and exactly dissects the submucosal layers without damaging the muscular layers. ESD is a potentially useful treatment to remove intestinal lipomas. PMID:27843426

    Lipoma arborescens is a benign tumor, but it may be a reactive process to other disorders, and its clinical, analytical, radiological and ultrasound presentation may be redundant to any synovial tumor. Despite the characteristic feature on magnetic resonance imaging (MRI), the correct differential diagnosis in atypical presentation, and the need for timely removal of the lesion to prevent joint damage, forces, ultimately, to invasive procedures. The clinical case reported here, fourth described in English language publications on the polyarticular form, also presented other specificities related to one of the swellings, in the knee. Because of its atypical location in the popliteal fossa, recurrent episodes of joint effusion, personal history of knee trauma, pulmonary tuberculosis, and family history of rheumatoid arthritis required particular attention. This process was hampered by the refusal of knee (and ankle) surgery by the patient. He accepted surgical removal of the swellings of the wrists, for aesthetical reasons, with pathologic confirmation of the diagnosis, and clinical success in that location. MRI of the knee showed the typical image of lipoma arborescens, but also other changes that compromise the prognosis.

    Three men aged 40 to 60 years presented with rare lumbar spinal intradural lipomas without spina bifida manifesting as worsening numbness, pain of the lower extremities, and bladder dysfunction. All 3 patients underwent decompressive laminectomy. The lipoma and cauda equina nerves were dissected from the dura mater under the operating microscope, untethering the spinal cord and returning the cauda equina nerves to the original position. Duralplasty was performed using an expanded polytetrafluoroethylene sheet. Postoperatively, all patients experienced improvement of their neurological deficits. In the surgical treatment of spinal lipomas, the primary purpose is untethering and decompression, which can be achieved by untethering the spinal cord, returning the cauda equina nerves to the normal position, laminectomy, and duralplasty, without removal of the lipoma.

    Introduction Adult intussusception is rare. Lipoma is the second most common benign tumor of the colon and most common to cause colonic intussusception in adults, but rare. Presentation of case A 35-years-old male presented with a history of intermittent abdominal pain and bright red rectal bleeding, with symptoms waxing and waning for one month. On physical examination, the abdomen was distended with tenderness over the periumbilical, suprapubic, and left lower quadrant regions with guarding. CT demonstrated colo-colonic intussusception of the sigmoid colon with a 2.3 cm × 2.6 cm intra-mural lipoma of the rectosigmoid region. The patient underwent an exploratory laparotomy with partial reduction of the intussusception, sigmoid colon resection and end colostomy. Histopathology confirmed a 2.5 cm sub-mucosal lipoma without evidence of malignancy. Discussion Sixty–sixty five percent of cases with intussusception of the large bowel in adults are related to a malignant etiology and most cases of sigmoidorectal intussusception reported in the literature are secondary to underlying malignancy. Colo-colic intussusception is the most common type of intussusception in adults. The incidence of lipomas of the large intestine is reported to range from 0.035% to 4.4%. Ninety percent of colonic lipomas are submuscosal and are mostly located in the right hemicolon. Only 25% of patients with colonic lipoma develop symptoms. Colonic lipomas of the rectosigmoid region represent a very rare occurrence and subsequent etiology for sigmoidorectal intussusceptions in adults. Conclusion Colonic lipoma should be considered in the differential diagnosis of adults with intussusception, with reduction and resection leading to excellent results. PMID:25839433

    Being rare tumors of the heart, cardiac lipomas are usually discovered incidentally during non-cardiac-related examinations of the chest. Although they are reported to be typically solitary, multiplicity has been described in tuberosclerosis patients. Here we reported the multidedector-row computer tomography (MDCT) findings of a nontuberosclerosis case with multiple cardiac lipomas along with pericardial lipomatosis, who presented with symptoms of left heart failure after a hysterectomy surgery but otherwise healthy before that operation.

    Background Lipoma is the most common benign tumour of the human body, being intraosseous involvement very rare. Just 1 to 4% of all cases of lipoma are located in the oral cavity, only 0.1% being intraosseous. The jaw is its most uncommon bone location. Etiology of intraosseous lipoma (IOL) is unknown, although several theories have been proposed. Usually asymptomatic, the symptoms, when present, will depend on its location and size. Its origin may be intraosseous or juxtacortical. A biopsy is essential for diagnosis, and definitive treatment involves resection or curettage of the lesion. The aim of this paper is to present a new case of intramedullary intraosseous lipoma of the mandible with involvement of the left mandibular ramus and condylar neck. Material and Methods A case of intramedullary intraosseous lipoma (IOL) on the left mandibular ramus and condyle is presented. No history of trauma in temporomandibular joint existed. The radiology showed a radiolucent multi-lobulated lesion with values of attenuation in the range of fat. Curettage is performed and the histopathology showed a conglomerate of adipocytes without trabeculae, calcifications or atypia. Results According to the bibliography 24 cases of mandibular IOL have been described. This is the second reported case of condylar involvement and the first with cortical expansion. Conclusions Lipoma intraosseous is a very rare benign bone neoplasm. Histology is required for the differential diagnosis from other radiolucent lesions. The IOL treatment is the curettage with a good prognosis, although malignant transformation to liposarcoma has been reported in other locations. It is a disease with a difficult differential diagnosis, therefore the publication of new cases is important. Key words:Intraosseous lipoma, lipoma, jaw tumour, condylar tumour. PMID:28298998

    Lipoma arborescens is a rare intra-articular disease that is usually monoarticular and is characterized by extensive proliferation of the synovial villi and hyperplasia of the subsynovial fat. The synovial tissue is progressively replaced by mature fat cells in the synovial membrane. The present study reports a case of a rare condition of lipoma arborescens that was simultaneously intra-articular (glenohumeral joint) and in the subacromial-subdeltoid bursa, in association with a torn supraspinatus tendon. The clinical, histological and radiographic presentations and treatment are discussed here. The description of this case includes radiographic and magnetic resonance evaluations and pathological examination. Although lipoma arborescens is a rare condition, it should be taken into consideration in cases presenting synovial hyperproliferation and synovial fat replacement. PMID:27047861

    Well-differentiated liposarcoma represents a radiographic diagnostic dilemma. To determine the accuracy, interrater reliability, and relationship of stranding, nodularity, and size in the MRI differentiation of lipoma and well-differentiated liposarcoma, MRI scans of 60 patients with large (>5 cm), deep, pathologically proven lipomas or well-differentiated liposarcomas were examined by 10 observers with subspecialty training blinded to diagnosis. Observers indicated whether the amount of stranding, nodularity, and size of each tumor suggested a benign or malignant diagnosis and rendered a diagnosis of lipoma or well-differentiated liposarcoma. The accuracy, reliability, and relationship of stranding, nodularity, and size to diagnosis were calculated for all samples. 69% of reader MRI diagnoses agreed with final pathology diagnosis (95% CI 65-73%). Readers tended to err choosing a diagnosis of liposarcoma, correctly identifying lipomas in 63% of cases (95% CI 58-69%) and liposarcomas in 75% of cases (95% CI 69-80%). Assessment of the relationship of stranding, nodularity, and size to correct diagnosis showed that the presence of each was associated with a decreased likelihood of a lipoma pathological diagnosis (P < 0.01). While the radiographic diagnosis of lipoma or well-differentiated liposarcoma cannot be made with 100% certainty, experienced observers have a 69% chance of rendering a correct diagnosis.

    Lipoma arise in almost 50% of all soft tumours. The neck lipomas are rare tumours that may present as painless masses with slow growth, in the lateral portions of the neck. Some lipomas, such as the one studied in our case, grow deep in the subcutaneous tissue, in close contact with muscles. Here, we report a case of lipoma extending from pre-tragal region up to the ascending branch of the mandible in a 62 year old man, treated with enucleation. The inferior margin of lipoma involved the pharyngeal and the superior margin was achieved by the top of the skull base. The mass of lipoma caused breathing difficulties in the patient, preventing regular sleep. No complication was recorded in the post-operative period and no further surgery was performed. The complete resolution after one year's follow-up, together with the rarity of the anatomical site, makes this case worthy of description. A correct diagnosis facilitated removal of this lesion with a surgical method.

    The impingement syndrome is defined by the compression of the rotator cuff tendons against the coracoacromial arch. Several factors contribute to this condition and they are classified as structural or functional factors. The former are changes in the coracoacromial arch, proximal humerus, bursa and rotator cuff, and the latter are related to the mechanism of the upper limb by means of synchronized activity and balanced between the rotator cuff and scapular girdle muscles. The authors report here a case of parosteal lipoma of the proximal humerus, located between the muscles deltoid, teres minor and infraspinatus causing clinical signs of impingement. It is a rare occurrence, characterized as a structural cause for the onset of this symptom. PMID:25167335

    Authors report the case of a 51-year-old man, presenting with epigastralgia of recent onset. Physical exam was unremarkable. Endoscopy revealed a large, ulcerated, submucosal, antral tumor. CT scan reveals an antral mass with fat attenuation. The patient underwent a total gastrectomy. Macroscopic examination identified in the antral wall a 9-cm, well-circumscribed, nodular lesion, with a yellow, greasy cut surface. On histological examination, the tumor was composed of a mature adipocytes proliferation, showing significant variation in cell size, associated to some lipoblasts. Nuclei were sometimes large, slightly irregular, but without hyperchromasia nor mitosis. Diagnosis of a well-differentiated liposarcoma was suspected and molecular cytogenetic analyses showed no MDM2 nor CDK4 gene amplification on fluorescent in situ hybridization. The diagnosis of lipoma was made. Twelve months following surgery, the patient is doing well. PMID:23308321

    2016-01-01

    Lipomas are the most commonly encountered benign mesenchymal tumors, but their occurrence in the head and neck is rare, even more at the level of the parotid region where they can be found nearby the parotid capsule, inside the capsule, or within the gland. In addition, lipomas involving the deep parotid lobe are extremely unusual. That is why lipomas are not often considered for differential diagnosis of parotid lumps. Concerning diagnostic tools, magnetic resonance imaging (MRI) is nowadays considered as the main imaging examination for parotid lipomas due to a characteristic signal intensity on T1- and T2-weighted images. Furthermore, even if the cost of MRI is nearly three times that of computed tomography, MRI is accurate, safe, and has few biological costs for the patient. In this reported case, MRI provided all information for either diagnosis or preoperative planning being the best diagnostic tool regarding tumor margin characteristics and surrounding tissues’ involvement. Concerning treatment, surgical excision of parotid masses is always mandatory for definitive diagnosis, but it is challenging because of the facial nerve. For this reason, a well-established surgical technique is mandatory for success. The authors present a rare case of parotid gland lipoma arising from the deep lobe and discuss diagnostic tools and surgical technique. PMID:28299278

  9. Novel method of minimally invasive removal of large lipoma after laser lipolysis with 980 nm diode laser.

    2011-01-01

    Lipomas are the most common benign tumor of the soft tissue, often presenting as soft, mobile subcutaneous masses. These lesions are often removed for cosmetic reasons, although they may be removed secondary to considerable discomfort or paresthesias. The large majority of lipomas appear as small, solitary lesions that are best removed by surgical excision. However, surgical removal of large (>10 cm) or multiple lesions may result in significant scarring. Tumescent local anesthesia and liposuction of larger lesions has been successful in a number of cases although this technique can be hindered by overly fibrous lesions. Laser lipolysis, performed alone or before liposuction, can further facilitate removal of these lesions. This technique is a minimally invasive and effective method of lipoma removal, resulting in an excellent cosmetic outcome. This report describes step-by-step removal of a large lipoma located on the back, as well as a review of currently employed techniques for minimally invasive treatment of lipomas. © 2011 Wiley Periodicals, Inc.

Chest computed tomography(CT) showed a dome-shaped and homogeneous mass with smooth surface on the left diaphragm. CT showed 50×60 mm hypodense mass and partly interrupted diaphragm. Magnetic resonance imaging( MRI) revealed fat signal intensity on both T1 and T2 weighted image and fat suppressed T1 image. Bochdalek hernia or diaphragm lipoma was suggested and surgery was done. Yellowish round tumor on the diaphragm was resected. The omentum was easily separated from the tumor. Histopathological finding revealed the lipoma cell invading into striated muscle of diaphragm, and the tumor was diagnosed as a mature lipoma originated from diaphragm.

    Although lipomas are among the most frequent tumors in the human body, their presentation in the oral cavity is not common. Oral cavity lipomas usually show a slow painless and assymptomatic growing. When these tumors reach big sizes, they can cause compressive symptons and deformities. In this paper we present the case of a patient in whom oral lipoma was the final finding in the differential diagnosis of a chronic mucosal ulcer. CT scan and MRI images and microscopical examination after fine-needle aspiration were the clue for the final diagnosis. The surgical excision of the tumor was the basis for the healing of the ulcer. We also review the most relevant and recent literature about clinic, diagnosis and treatment for these tumors.

    A 15-year-old male cynomolgus monkey (Macaca fascicularis) showed large bilateral masses in the maxillary sinus. In histopathological examination, both masses revealed benign medullary lipomas within the turbinate bones. The tumors were composed of well-developed lipocytes, trabecular bones and a few blood vessels. Although we initially diagnosed the tumor as bilateral lipomas in the nasal turbinates, it was not differentiated from lipomatous hamartoma. Findings, such as unique symmetrical proliferation, lack of border from the normal marrow and the intact surrounding tissue, indicated a lipomatous hamartoma/hamartomatous lipoma, thought to be a suitable diagnosis of the lesion. Of most interest was that such a proliferating lesion occurred in the nasal turbinate. PMID:27499062

    An extremely obese, mixed breed dog, with severe bilateral hip osteoarthritis was presented with progressive hindlimb lameness. In addition, three giant lipomas were diagnosed, one causing mechanical irritation within the left axillary region. Previous treatments of dietary weight loss and non-steroidal anti-inflammatory drugs had failed. Minimally invasive liposuction of the lipomas was performed, resulting in weight loss of 3 kg, representing 10 per cent of the dog's bodyweight. Conservative treatment was continued, and the dog improved rapidly postoperatively. Liposuction of lipomas may be considered as an alternative to traditional surgical resection in cases where seroma formation and delayed wound healing may be expected. Acute weight loss through liposuction may improve lameness associated with osteoarthritis and motivate the owner compliance for further weight loss.

    Lipomas of the colon are relatively rare benign soft tissue tumors derived from mature adipocytes of mesenchymatic origin. During colonoscopy, surgery or autopsy they are generally discovered incidentally. Most cases are asymptomatic, with a small tumor size, and do not need any special treatment. However, in the cases with larger in size of tumor some symptoms such as anemia, abdominal pain, constipation, diarrhea, bleeding, or intussusception may be presented. We reported a 47-year-old woman with colonic intussusception in the descending colon caused by colonic lipoma and diagnosed after surgical exploration for obstructive colonic mass. PMID:28224035

    Spindle cell lipomas (SCL) are typically tumors of the upper back/neck (shawl region) of men (80% to 90%). In general, there is a frequent tendency to restrict the diagnosis to this specific clinical scenario and a hesitancy to diagnose SCL in women. We hypothesized that SCL in women have a more varied presentation. A total of 395 SCL were diagnosed at our institution over the last 11 years. The diagnosis of SCL in women was confirmed by re-review. Immunohistochemical stains for CD34, desmin, estrogen receptor, and p16 were performed. In a subset, fluorescence in situ hybridization to detect Retinoblastoma1 (RB1) gene deletion was performed. Of 395 SCLs, 331 (86%) occurred in men; 53 (14%) occurred in women (11 cases excluded). Of the 64 SCL in women, 58 had available material. In total, 53 of 58 were confirmed as SCL. Women were younger at diagnosis (median, 51 y; range, 5 to 76 y) compared with men (64 y; range, 23 to 98 y), P<0.0001, t test. SCL in women typically occurred outside the shawl distribution (36/53, 68%) compared with men (95/331, 29%) (P<0.001), including extremities (16/53, 30% vs. 32/331, 10%) and face (11/53, 21% vs. 47/331, 14%). Dermal SCL in women were also relatively common (16/53, 30%). The cases demonstrated varying proportions of bland spindled cells, ropey collagen, myxoid matrix, and adipocytes. By immunohistochemistry, 46/46 were CD34, 48 of 48 were desmin negative, 33 of 42 were estrogen receptor negative, and 29 of 42 had loss of p16 expression. In total, 12 of 14 showed RB1 loss by fluorescence in situ hybridization. SCL in women frequently occurs in unconventional locations and in at a slightly younger patient age.

    We present a rare cause of intestinal obstruction in an adult, due to ileo-colic intussusception by a lipoma of the ileo-cecal valve and its ultrasonographic presentation. The case presented in emergency for spontaneously appearing and disappearing palpable elastic mass in the right iliac fossa. The ultrasonographic examination raised the suspicion of an ileo-colic intussusception due to a polypoid tumor. The contrast-enhanced computed tomography confirmed the finding and suggested that the polypoid tumor was more likely a lipoma. Right hemicolectomy and cholecystectomy were performed and the pathological examination confirmed the lipoma. The evolution of the patient was favourable and uneventful.

    The authors present the case of a 60-year-old woman with a neck lipoma that developed dumb-bell extradural extension, causing radiculopathy. To the best of the authors' knowledge, this is the first report of a lipoma originating in the neck with dumb-bell extradural extension through the intervertebral foramen and into the spinal canal. The lipoma was first excised from the foramen via a posterior approach to allow decompression of the nerve roots. The remaining lipomatous tissue was then resected via an anterior approach to avoid the region around the vertebral artery.

    Occipital neuralgia (ON) is commonly characterized by a neuralgiform headache accompanied by a paroxysmal burning sensation in the dermatome area of the greater, lesser, or third occipital nerve. The authors report a rare case of ON caused by an intramuscular lipoma originating from the lesser occipital nerve.A 52-year-old man presented with sharp pain in the left postauricular area with a 3 × 2-cm palpable mass. Computed tomography revealed a mass suspiciously resembling an intramuscular lipoma within splenius muscle. In the operation field, a protruding mass causing stretching of the lesser occipital nerve was found. After complete resection, the neuralgiform headache symptom had resolved and the intramuscular lipoma was confirmed through histopathology.Previous studies on the causes of ON have reported that variation in normal anatomic structures results in nerve compression. Occipital neuralgia, however, caused by intramuscular lipomas in splenius muscles have not been previously reported, and the dramatic resolution following surgery makes it an interesting case worth reporting.

    Intussusception is a relatively common cause of intestinal obstruction in children but a rare clinical entity in adults, representing fewer than 1% of intestinal obstructions in this patient population. Colonic lipomas are uncommon nonepithelial neoplasms that are typically sessile, asymptomatic and incidentally found during endoscopy, surgery, or autopsy. A 55-year old man visited our emergency department with severe abdominal pain, multiple episodes of vomiting, abdominal distension. Abdominal ultrasound sonography and computed tomography showed a sausage-shaped mass presenting as a target sign, suggestive of intussusception. Surgery revealed a hard elongated mass in the right colon wihch telescoped in the transverse colon and caused colo-colonic intussusception. Rhigt hémicolectomy was performed and pathology documented a mature submucosal lipoma of the colon. We describe the difficulties in diagnosis and management of this rare cause of bowel obstruction and review the literature on adult intussusceptions. A large submucosal lipoma is a very rare cause of colon intussusception that presents as intestinal obstruction in patients without malignancy. CT and magnetic resonance imaging remain the methods of choice for studying abdominal lipomas, particularly those rising into the layers of the colonic wall. Surgical resection remains the treatment of choice and produces an excellent prognosis.

    We report herein the case of a giant lipoma of the greater omentum that was treated by laparoscopic surgery. A 71-year-old male patient was admitted with a diagnosis of sigmoid colon cancer. During preoperative examination, a gallbladder stone and an intra-abdominal giant lipoma were accidentally diagnosed. Laparoscopic examination revealed a smooth-surfaced, giant yellow tumor at the lower border of the greater omentum that was unattached to the surrounding organs. After laparoscopic resection of the tumor and cholecystectomy, a 10-cm midline incision was made in the lower abdomen to remove the tumor and the gallbladder. We then performed a sigmoidectomy for sigmoid colon cancer through the same laparotomy. The resected tumor measured 29 x 19 x 3 cm and weighed 1250 g, and a histopathologic examination revealed a benign lipoma. Laparoscopic examination and resection of a giant lipoma of the omentum are particularly useful.

    Five studies tested the common assumption that women prefer nonconformist men as romantic partners, whereas men prefer conformist women. Studies 1 and 2 showed that both men and women preferred nonconformist romantic partners, but women overestimated the extent to which men prefer conformist partners. In Study 3, participants ostensibly in a small-group interaction showed preferences for nonconformist opposite-sex targets, a pattern that was particularly evident when men evaluated women. Dating success was greater the more nonconformist the sample was (Study 4), and perceptions of nonconformity in an ex-partner were associated with greater love and attraction toward that partner (Study 5). On the minority of occasions in which effects were moderated by gender, it was in the reverse direction to the traditional wisdom: Conformity was more associated with dating success among men. The studies contradict the notion that men disproportionately prefer conformist women. © 2015 by the Society for Personality and Social Psychology, Inc.

    Lipoma arborescens is a chronic, slow-growing, intra-articular lesion of benign nature, which is characterized by villous proliferation of the synovium, with replacement of the subsynovial connective tissue by mature fat cells. It usually involves the suprapatellar pouch of the knee joint. It is not a neoplasm but is rather considered a nonspecific reactive response to chronic synovial irritation, due to either mechanical or inflammatory insults. We report three cases of lipoma arborescens affecting the knee, the first in a young male without previous history of arthritis or trauma, the second in a 58-year-old male associated with osteoarthritis, and the final in a 44-year-old male diagnosed with psoriatic arthritis, which cover the entire pathologic spectrum of this unusual entity. We highlight the clinical findings and imaging features, by emphasizing especially the role of MRI, in the differential diagnosis of other, more complex intra-articular masses. PMID:28243256

    The case of a four-year-old child is described who presented to our institution with cervicothoracic deformity and a two-year history of progressive paraparesis. His past medical history was significant for meningocele which was closed at age two months. Imaging studies revealed severe congenital kyphosis with a hypoplastic t3 vertebra, as well as a tethered filum terminale with a conus lipoma. the spinal cord was found to be severely compressed at the apex of the kyphotic deformity. Discussion is focused on the diagnosis of tethered cord syndrome, and treatment options. In particular, this case required careful thought on the order of events, which followed initial tethered cord release and removal of the conus lipoma, and subsequent kyphectomy and fusion of the upper thoracic spine. A favorable clinical outcome was obtained with complete reversal of the paraparesis. PMID:17907436

    Lipomatous extra-axial lesions in the Sylvian fissure are a rare entity. Their identification, however, is usually simple if a systematic radiological approach is adopted. The best line of management for these lesions is still a matter of controversy and fraught with complications. We present a case of a Sylvian fissure lipoma referred to our neurosurgery services with symptomatic seizures and in a post-traumatic patient. The radiological differentiating features of intracranial lipomas and intracranial dermoids have been discussed. The unusual location of the lesion, in combination with the history of seizures and the nature of presentation (trauma being a red-herring) make this case an interesting find. The lesion was managed conservatively with good outcomes at follow up, on anti-epileptic medications. PMID:24967029

    Gastric lipoma is considered a rare condition that may constitute a challenging diagnosis. A 51-year-old woman presented dysphagia and abdominal pain, and an upper digestive endoscopic study disclosed a gastric tumor located in the submucosa of the pyloric antrum. Conclusive diagnosis was established after repeated endoscopic biopsies, and the patient was subjected to an atypical gastrectomy, which evolved into a pyloric stenosis. This complication was appropriately corrected and the patient remains symptomless, under outpatient surveillance.

    The spinal anomaly designated dorsal dysraphism with lipoma (lipomyeloschisis) consists of skin-covered, focal spina bifida; focal partial clefting of the dorsal half of the spinal cord; continuity of the dorsal cleft with the central canal of the cord above (and occasionally below) the cleft; deficiency of the dura underlying the spina bifida; deep extension of subcutaneous lipoma through the spina bifida and the dural deficiency to insert directly into the cleft on the dorsal half of the cord; variable cephalic extension of lipoma into the contiguous central canal of the cord; and variable ballooning of the subarachnoid space to form an associated meningocele. The variable individual expressions of the anomaly are best understood by reference to their archetypal concept. Careful analysis of radiographic and surgical findings in human lipomyeloschisis and correlation with an animal model of lipomyeloschisis indicate that plain spine radiographs and high-resolution metrizamide computed tomographic myelography successfully delineate the precise anatomic derangements associated with lipomyeloschisis and provide the proper basis for planning surgical therapy of this condition.

    Introduction. Intussusception is a rare clinical entity in adults (<1% of intestinal obstructions). Colonic intussusception is even rarer, particularly when caused by lipomas. Case Presentation. A 47-year-old woman presented to our emergency department complaining of abdominal pain with vomiting and diarrhoea. X-ray and CT showed bowel obstruction due to ileocolonic and colocolonic intussusception; a giant colonic lipoma (9 × 4 × 4 cm) was recognizable immediately distally to the splenic flexure of the colon. The patient underwent emergency laparotomy and right hemicolectomy. Assessment of the resected specimen confirmed the diagnosis of giant colonic polypoid lesion near to the ileocecal valve, causing a 12 cm long intussusception with moderate ischemic damage. Conclusion. Colonic obstruction due to intussusception caused by lipomas is a very rare condition that needs urgent treatment. CT is the radiologic modality of choice for diagnosis (sensitivity 80%, specificity near 100%); since the majority of colonic intussusceptions are caused by primary adenocarcinoma, if the etiology is uncertain, the lesion must be interpreted as malignant and extensive resection is recommended. At present, surgery is the treatment of choice and determines an excellent outcome.

    Although social animals frequently make decisions about when or with whom to cooperate, little is known about the underlying mechanisms of partner choice. Most previous studies compared different dyads’ performances, though did not allow an actual choice among partners. We tested eleven ravens, Corvus corax, in triads, giving them first the choice to cooperate with either a highly familiar or a rather unfamiliar partner and, second, with either a friend or a non-friend using a cooperative string-pulling task. In either test, the ravens had a second choice and could cooperate with the other partner, given that this one had not pulled the string in the meantime. We show that during the experiments, these partner ravens indeed learn to wait and inhibit pulling, respectively. Moreover, the results of these two experiments show that ravens’ preferences for a specific cooperation partner are not based on familiarity. In contrast, the ravens did show a preference based on relationship quality, as they did choose to cooperate significantly more with friends than with non-friends and they were also more proficient when cooperating with a friend. In order to further identify the proximate mechanism of this preference, we designed an open-choice experiment for the whole group where all birds were free to cooperate on two separate apparatuses. This set-up allowed us to distinguish between preferences for close proximity and preferences to cooperate. The results revealed that friends preferred staying close to each other, but did not necessarily cooperate with one another, suggesting that tolerance of proximity and not relationship quality as a whole may be the driving force behind partner choice in raven cooperation. Consequently, we stress the importance of experiments that allow such titrations and, suggest that these results have important implications for the interpretations of cooperation studies that did not include open partner choice.

  17. Resolution of intussusception after spontaneous expulsion of an ileal lipoma per rectum: a case report and literature review

    PubMed Central

    2014-01-01

    We herein report a case of spontaneous rectal expulsion of an ileal lipoma in a 65-year-old female patient who presented with recurrent attacks of subacute intestinal obstruction. During each episode, the patient developed severe abdominal pain and expelled a fleshy mass from her rectum. The fleshy mass was histopathologically diagnosed as a lipoma comprising fat cells, fibers, and blood vessels. Upon expulsion, the pain disappeared and the intussusception was immediately resolved. Colonoscopic examination revealed a 2.5-cm diameter ulcerated lesion near the ileocecal valve, which was confirmed to be inflammation by pathological examination. A subsequent barium series revealed a normal colonic tract, and the patient remained completely symptom-free for 4 months after the incident. According to the relevant literature and our clinical experience, the treatment method for a lipoma depends on the patient’s clinical manifestations and the size of the tumor. However, the various diagnostic and therapeutic modalities currently available continue to be debated; whether an asymptomatic lipoma requires treatment is controversial. When histopathological examination results allow for the exclusion of malignant lesions such as sarcoma, a lipoma can be resected surgically. PMID:24884620

    Adrenal lipomas are rare, small, benign, non-functioning tumors, which must be histopathologically differentiated from other tumors such as myelolipomas or liposarcomas. They are usually identified incidentally during autopsy, imaging, or laparotomy. Occasionally, they may present acutely due to complications such as abdominal pain from retroperitoneal bleeding, or systemic symptoms of infection. We report a giant adrenal lipoma (to the best of our knowledge, the second largest in the literature) clinically presenting with chronic mild postprandial pain. A 54-year-old Caucasian woman presented several times over a period of 10 years to various emergency departments complaining of long-term mild postprandial abdominal pain. Although clinical examinations were unrevealing, an abdominal computed tomography scan performed at her most recent presentation led to the identification of a large lipoma of the left adrenal gland, which occupied most of the retroperitoneal space. Myelolipoma was ruled out due to the absence of megakaryocytes, immature leukocytes, or erythrocytes. Liposarcoma was ruled out due to the absence of lipoblasts. The size of the lipoma (16 × 14 × 7 cm) is, to the best of our knowledge, the second largest reported to date. After surgical resection, our patient was relieved of her symptoms and remains healthy six years postoperatively. Physicians should be aware that differential diagnosis of mild chronic abdominal pain in patients presenting in emergency rooms may include large adrenal lipomas. When initial diagnostic investigation is not revealing, out-patient specialist evaluation should be planned to enable appropriate further investigations.

    Background Differentiating large lipomas from atypical lipomatous tumors (ALT) is challenging and preoperative management guidelines are not well-defined. The diagnostic ambiguity leads many surgeons to refer all patients with large lipomatous masses to an oncologic specialist, perhaps unneccessarily. Study Design In this retrospective cohort study of patients with nonretroperitoneal lipomatous tumors, preoperative characteristics discernible without invasive diagnostic procedures were evaluated for diagnostic predictive value. Results 319 patients (256 with lipomas, 63 with ALTs) treated between 1994 and 2012 were identified. Patients with ALTs were older (60.5 vs. 53.5 years, p<0.0001), had larger tumors (16.0 vs 8.3 cm, p<0.0001), had tumors more often located on an extremity (88.9% vs. 60.5% torso, p<0.0001), and more frequently had a history of prior operations at the same site, exclusive of excision leading to diagnosis and referral (20.6% vs. 5.9%, p=0.001). Local recurrence was observed in 2 patients with lipomas (0.8%) vs. 14 with ALTs (22.6%, p<0.0001). No patients with ALTs developed distant metastases or disease-specific mortality with a median follow-up of 27.4 months (range 0–164.6 months). On multivariate analysis age ≥55 years, tumor size ≥10 cm, extremity location, and history of prior operations were predictors for diagnosis of ALT (p<0.05). Conclusions Characteristics of lipomatous masses that are associated with a diagnosis of ALT include patient age ≥55 years, tumor size ≥10 cm, previous resection, and extremity location (vs torso). These easily identifiable traits may guide surgical management or referral to a specialist. PMID:24074812

    Lipomatous lesions rarely involve the bronchial tree, and detailed morphologic and molecular cytogenetic analysis of these tumors is lacking. The clinicopathologic features of 12 endobronchial lipomatous neoplasms were studied, with ancillary fluorescence in situ hybridization performed in subsets of cases for CPM, which is amplified in atypical lipomatous tumors/well-differentiated liposarcomas (ALT/WDL), and HMGA1 and HMGA2, which are often rearranged in lipomas. The cases occurred predominately in older men (91%) (age range 44 to 80 y, mean 65 y). Most patients (80%) had a former or current history of heavy smoking (20 to 100 pack-years). Three patients had concurrent pulmonary squamous cell carcinoma, and 1 had a history of multiple lung cancers. Most lesions were small (<2.5 cm) and discovered incidentally. A subset of tumors showed atypical morphologic features that would be suggestive of ALT/WDL in soft tissue sites, including regions of fibrosis and scattered hyperchromatic stromal cells. However, all cases with atypia were CPM negative and behaved in a clinically benign manner. Seven cases were tested for HMGA1 and HMGA2 rearrangement; 4 showed HMGA2 rearrangement, and 1 showed HMGA1 rearrangement, consistent with lipomas. Two cases were negative for HMGA1/2 rearrangements. We conclude that endobronchial lipomatous neoplasms represent lipomas, even in the presence of morphologic features suggestive of ALT/WDL. Ancillary fluorescence in situ hybridization testing may be very valuable in the analysis of these rare tumors, as true ALT/WDL seem to be very rare or nonexistent at this anatomic site.

    Spindle cell lipoma of the hypopharynx is an extremely rare entity. Here, we present the first case of this lesion originated in the cricopharyngeal region, with symptoms of chronic progressive dysphagia, which can be confused with other pathologies; endoscopic and magnetic resonance imaging (MRI) evaluation are the methods of choice for its diagnostic approach. The best therapeutic approach is endoscopic resection with rapid recovery and few complications. Long-term followup is recommended, either endoscopic or imaging, given that it can be confused with an undiagnosed liposarcoma; additionally, its long-term behavior is unknown. PMID:23326743

    We present a case with a 46-year-old woman who had experienced six days of abdominal pain and some days of anal bleeding. She had no prior medical history. At the clinical examination it was found that she had a soft abdomen, but there was tenderness in the lower part. A computed tomography showed an intussusception of the sigmoideum into the rectum. An oncological resection was performed, since it could not at the time of the operation be determined if it was a malignant proces. The histology showed a benign submucosal lipoma.

    Jejunal lipomata are an unusual cause of adult intussusception. We report a case of a 44-year-old Chinese woman who presented with a 3-day history of abdominal pain and nausea; she had a 5-year history of similar episodic symptoms after meals. Contrast-enhanced CT revealed a fat-density lead point in the jejunum resulting in intussusception. Single port laparoscopic surgery was performed with reduction of the intussusception, bowel resection and primary anastamosis. Histology confirmed a benign submucosal lipoma. We discuss the recent published literature on this rare entity and show CT images and intraoperative pictures. 2014 BMJ Publishing Group Ltd.

    Subacromial impingement syndrome is a common cause of shoulder pain in young adults and seniors at present. The etiology of this syndrome is associated with several shoulder disorders, most related to aging, overhead activities, and overuse. The subacromial space is well circumscribed and limited in size, and soft-tissue growing lesions, such as tumors, can endanger the normal function of the shoulder girdle. We present a case of shoulder impingement syndrome caused by an intramuscular lipoma of the supraspinatus muscle in the subacromial space in a 50-year-old male bank manager. Radiographs, magnetic resonance imaging, and a computed tomography scan showed a well-circumscribed soft-tissue tumor at the supraspinatus-musculotendinous junction. It was arthroscopically inspected and dissected and complete marginal excision was performed through a conventional augmented anterolateral portal, avoiding the need to open the trapezius fascia or perform an acromial osteotomy. Microscopic study showed a benign lipoma, and the shoulder function of the patient was fully recovered after a rehabilitation period of 4 months. This less invasive technique shows similar results to conventional open surgery. PMID:26759779

    A 66-year-old man was referred to our hospital with an increasing subepithelial lesion in the gastric antrum. Using esophagogastroduodenoscopy, a tumor with a steep, 20-mm-high rise protruding in the lumen was observed. The mucosal surface of the tumor was reddish, with ulcers forming at the base. Moreover, the tumor was mobile and soft. A biopsy specimen was taken from the ulcer, but tumor tissue was not collected from the submucosa. Endoscopic ultrasonography (EUS) showed a high echoic mass in the submucosa. However, because the mucosal surface of the ulceration was red, the mesenchymal tumor with internal bleeding was inferred to be lipoma. Additionally, because the tumor was small, flexible, and soft, collecting tumor tissue under EUS-guided fine-needle aspiration was inferred as difficult. We were unable to make a final diagnosis because the lesion showed a small tumor with atypical macroscopic morphology. Therefore, endoscopic submucosa dissection (ESD) was chosen for the diagnostic treatment. Sodium hyaluronate sufficient for separation from the muscular layer was injected into the submucosa. Then submucosal dissection was performed just above the muscle layer. Results demonstrate the possibility of removing the tumor reliably without perforation. Pathological evaluation of the ESD specimen indicated a diagnosis of gastric lipoma.

    Painful total hip replacement remains a challenging problem because of the large amount of possible diagnoses. We report about a 64-year-old female patient who was misdiagnosed during 4 years as psychiatric. She suffered of excruciating left retrotrochanteric pain after the implantation of a cementless total hip replacement and revision because of recurrent hip dislocations. Walking was limited to short distances using two crutches. The work-up at this time included the usual diagnoses and remained unsuccessful. No loosening, infection or malposition of the prosthesis could be found, and she had no neurologic deficits in her operated leg. An MRI was obtained to visualize the retrotrochanteric soft tissues and showed a tight scar surrounding the sciatic nerve, which was also compressed by an adjacent lipoma. Therefore, she was reoperated on to remove the lipoma and the scar tissue around the sciatic nerve. To decrease the risk of recurrent scarring around the sciatic nerve, an adhesion barrier was applied before closure. One year after the operation, the patient has no neurologic deficit, no more pain and is able to walk unlimited distances without crutches. Scar tissue around the sciatic nerve is frequently observed during revision surgery. However, we feel that sciatic nerve entrapment by scar tissue should be a part of the differential diagnosis of painful THR. MRI may be a useful tool to achieve this diagnosis.

    We herein report a case of adult ileoileal intussusception induced by an ileal lipoma. A 68-year-old woman with a history of small intestinal tumors was admitted to our hospital with severe, colicky lower abdominal pain, similar to episodes experienced in the past. A barium meal enema at the initial admission demonstrated a small intestinal tumor in the ileum 30 cm proximal to the ileocecal valve. Abdominal ultrasound sonography and computed tomography showed a sausage-shaped mass presenting as a target sign in the right lower abdomen, suggestive of intussusception. There was also a round mass of fat attenuation representing a lipoma, which was considered the lead point of the intussusception. The patient underwent emergency surgery and partial resection of the ileum, including the ileal tumor, following reduction of the intussusception. The resected specimen contained a round tumor measuring 1.5 × 1.5 × 1.4 cm, which was diagnosed histopathologically as an intestinal lipoma. The patient made a satisfactory recovery and was discharged on postoperative day 10. The clinical characteristics of previously reported lipomas with intussusception are also discussed, including the relationships between the tumor size and symptoms or location.

    The current study developed and tested a multiple-stimulus-without-replacement (MSWO) assessment for potential sexual partners for use in research on human immunodeficiency virus. College students (N = 41) first completed an MSWO assessment and then completed a hypothetical purchase task for encounters with partners identified by the MSWO as high, median, and low preference. Overall, hypothetical purchase task responding was consistent with that from the MSWO, in that the highest valuation was observed for the high-preference partner and the lowest for the low-preference partner. Potentially interesting individual differences in purchase task responding, however, were obtained; some subjects showed differentiated responding among the 3 preference levels (n = 15), whereas others similarly valued high- and median-preference partners (n = 5), and others similarly valued low- and median-preference partners (n = 18). © 2016 Society for the Experimental Analysis of Behavior.

    Intracranial lipomas are rare, but 45% of them occur along the midline cisterns between the hemispheres and are often associated with corpus callosum hypoplasia and craniofacial defects. They are difficult to detect, as they are generally asymptomatic and visible by MRI or by postmortem examination. The exact cause of these interhemispheric lipomas is not known, but they arise from a developmental defect resulting in the maldifferentiation of mesenchymal cells into mesodermal derivatives that are not normally present. We have identified a new mouse mutant called tuft, exhibiting a forebrain, intracranial lipoma with midline craniofacial defects resembling frontonasal dysplasia (FND) that arose spontaneously in our wild-type 3H1 colony. The tuft trait appears to be transmitted in recessive fashion, but approximately 80% less frequent than the expected Mendelian 25%, due to either incomplete penetrance or prenatal lethality. MRI and histological analysis revealed that the intracranial lipoma occurred between the hemispheres and often protruded through the sagittal suture. We also observed a lesion at the lamina terminalis that may indicate improper closure of the anterior neuropore. We have mapped the tuft trait to within an 18 cM region on mouse chromosome 10 by microsatellite linkage analysis and identified several candidate genes involved with craniofacial development and cellular differentiation of adipose tissue. tuft is the only known mouse model for midline craniofacial defects with an intracranial lipoma. Identifying the gene(s) and mutation(s) causing this early developmental defect will help us understand the pathogenesis of FND and related craniofacial disorders. PMID:22246904

    2017-01-01

    Spindle Cell Lipoma (SCL) is an uncommon benign tumour of adipose tissue that is usually superficially located in the neck, back and shoulder region. Although it has characteristic histological features it can pose a diagnostic dilemma on cytology. It presents with a mixture of spindle cells, adipocytes, collagen fibres and a myxoid matrix in varying proportions sometimes with mild pleomorphism. Hence, it can be mistaken for other spindle cell, adipose and myxoid tumours which can be benign or malignant. We present a case of SCL of the back in a 47-year-old male, who presented with a slow growing lesion. Fine Needle Aspiration Cytology (FNAC) showed the characteristic cytological features described above and a diagnosis could be given after clinical correlation. We report this case as the cytology of this uncommon tumour has been described in relatively few cases and a correct pre-operative diagnosis will aid in proper management of this tumour.

    Paralysis of the posterior interosseous nerve (PIN) secondary to compression is a rare clinical condition. Entrapment neuropathy may occur at fibrous bands at the proximal, middle, or distal edge of the supinator. Tumors are a relatively rare but well-known potential cause. The authors present 2 cases of PIN lesions in which compression by a benign lipoma at the level of the elbow resulted in near transection (discontinuity) of the nerve. They hypothesize a mechanism-a "sandwich effect"-by which compression was produced from below by the mass and from above by a fibrous band in the supinator muscle (i.e., the leading edge of the proximal supinator muscle [arcade of Fröhse] in one patient and the distal edge of the supinator muscle in the other). A Grade V Sunderland nerve lesion resulted from the advanced, chronic compression. The authors are unaware of a similar case with such an advanced pathoanatomical finding.

    Partner choice is an important force underpinning cooperation in humans and other animals. Nevertheless, the mechanisms individuals use to evaluate and discriminate among partners who vary across different dimensions are poorly understood. Generally, individuals are expected to prefer partners who are both able and willing to invest in cooperation but how do individuals prioritize the ability over willingness to invest when these characteristics are opposed to one another? We used a modified Dictator Game to tackle this question. Choosers evaluated partners varying in quality (proxied by wealth) and fairness, in conditions when wealth was relatively stable or liable to change. When both partners were equally fair (or unfair), choosers typically preferred the richer partner. Nevertheless, when asked to choose between a rich-stingy and a poor-fair partner, choosers prioritized fairness over wealth-with this preference being particularly pronounced when wealth was unstable. The implications of these findings for real-world partner choice are discussed.

    Intussusceptions in adults is rare. Gastrointestinal lipomas are rare benign tumors and intussusceptions due to a gastrointestinal lipoma constitutes an infrequent clinical entity. Lipoma may develop as a benign tumor in all organs and rarely in large or small intestine. The present report describes a case of jejunojejunal intussusceptions in an adult with a history of colicky upper abdominal pain. Ileo-ileal invagination was diagnosed by computed tomography scan. Exploratory laparotomy revealed jejunojejunal intussusceptions secondary to a lipoma which was successfully treated with segmental intestinal resection. A review of the literature is also performed regarding this rare association revealing the diagnostic and therapeutic debates that exist. ABSTRACT (FRENCH): L'invagination chez les adultes est rare.

    Adult intussusception is rare and usually caused by a tumor acting as the lead point. Therefore, laparotomy should be considered for the treatment. Laparoscopic procedures for use in cases of adult intussusception have been recently reported; however, there is no consensus regarding the safety and efficacy. Here, we describe a successful case of laparoscopic management of an octogenarian adult intussusception caused by an ileal lipoma, which was preoperatively suspected. An 87-year-old male presented with progressive abdominal distention and vomiting. Contrast radiography of the small intestine showed an ileal tumor, and magnetic resonance imaging indicated a target-like mass, consistent with an ileal intussusception. The patient was suspected with an intussusception due to an ileal lipoma, and laparoscopic surgery was performed. An approximately 10-cm-long ileal intussusception with a preceding tumor was present, and partial resection of the ileum, including the tumor, was performed. Macroscopic examination of the excised specimen showed a pedunculated tumor measuring 4.0 × 3.5 × 1.9 cm with an uneven surface, yielding a histological diagnosis of lipoma. The patient had an uneventful recovery and was discharged on postoperative day 8. This successful case showed that laparoscopic surgery can be a useful, safe, and efficacious procedure for adult intussusception, even in octogenarians.

    In a wide range of taxa, including baboons, close social bonds seem to help animals cope with stress and enhance long-term reproductive success and longevity. Current evidence suggests that female baboons may benefit from establishing and maintaining highly individuated relationships with a relatively small number of partners. Here, we extend previous work on the stability of female baboons' social relationships in three different ways. First, we assess the stability of females' social relationships in two distinct and geographically distant sites using the same method. Second, we conduct simulations to determine whether females' social relationships were more stable than expected by chance. Third, we examine demographic sources of variance in the stability of close social bonds. At both sites, females' relationships with their most preferred partners were significantly more stable than expected by chance. In contrast, their relationships with less preferred partners were more ephemeral, often changing from year to year. While nearly all females experienced some change in their top partners across time, many maintained relationships with top partners for several years. Females that lived in smaller groups and had more close kin available had more stable social relationships than those that lived in larger groups and had fewer close kin available.

    In the present study, heterosexual college women (N=327) and men (N=160) were asked about their body type preferences for (hypothetical) romantic partners. Participants chose a particular silhouette value as ideal for a romantic partner, and rated how important it was to them for their partner to have this ideal body type. Men placed more importance on the body silhouette they chose for a partner than women did, and men's importance ratings were positively associated with the rated sexual permissiveness of their peer group and their total media use. Consuming sports media and watching reality television were the best media predictors of men's judgments about women's bodies. Less variability was explained in women's preferences for men partners' bodies, but endorsing adversarial sexual attitudes was positively related to judging the ideals chosen for men's bodies as important. Results were interpreted within both evolutionary and sociocultural theoretical frameworks.

  8. Homosexual mating preferences from an evolutionary perspective: sexual selection theory revisited.

    Studies in evolutionary psychology and sexual selection theory show that heterosexual men prefer younger mating partners than heterosexual women in order to ensure reproductive success. However, previous research has generally not examined differences in mating preferences as a function of sexual orientation or the type of relationship sought in naturalistic settings. Given that homosexual men seek partners for reasons other than procreation, they may exhibit different mating preferences than their heterosexual counterparts. Moreover, mating preferences may show important differences depending on whether an individual is seeking a long-term versus a short-term relationship. The purpose of the present study was to examine these issues by comparing partner preferences in terms of age and relationship type between homosexual and heterosexual men placing internet personal advertisements. Participants included 439 homosexual and 365 heterosexual men who placed internet ads in the U.S. or Canada. Ads were coded for the participant's age, relationship type (longer-term or short-term sexual encounter) sought, and partner age preferences. Significantly more homosexual than heterosexual men sought sexual encounters, although men (regardless of sexual orientation) seeking sexual encounters preferred a significantly wider age range of partners than men seeking longer-term relationships. These findings suggest that partner preferences are independent of evolutionary drives to procreate, since both types of men preferred similar ages in their partners. In addition, they highlight the importance of examining relationship type in evolutionary studies of mating preferences, as men's partner preferences show important differences depending upon the type of relationship sought.

  9. The value of physical attractiveness in romantic partners: modeling biological and social variables.

    PubMed

    Jonason, Peter K

    2009-04-01

    According to research on physical attractiveness, personal attributes such as gender, height, and self-perception are important in determining how much individuals value physical attractiveness in their romantic partners. In a survey of 228 college-aged participants, the ratings of the physical attractiveness of potential romantic partners were positively correlated with how much participants valued physical attractiveness in their long-term romantic partners. Individuals' partner preferences may be sensitive to their perceptions of themselves. Perceptions of the attractiveness of those in one's local area may also play a part in the development of such partner preferences through exposure.

. Cross-sectional exploratory study.
 100 counties in North Carolina. 281 partners of men with newly diagnosed localized prostate cancer. Participants completed a phone survey. Logistic regression analyses were used. Partners' involvement in treatment decision making, partner satisfaction with treatment, activities of partner involvement, and reasons for noninvolvement. Of the 228 partners (81%) related to decision making, 205 (73%) were very satisfied with the treatment the patients received, and partner involvement was congruent with patient preference in 242 partners (86%). Partners reported several reasons for noninvolvement. Most partners engaged in multiple activities during treatment decision making for localized prostate cancer and were satisfied with the patient's treatment. Partner involvement was mostly congruent with patient preference. Partners' active involvement in treatment decision making for localized prostate cancer (e.g., being involved in patients' conversations with doctors) should be encouraged and facilitated for those who prefer this type of decision making.

    The intraneural fibro-lipoma is a benign, uncommon tumor which is characterised with infiltration of the epineurium and perineurium by fibrofatty tissue. The preoperative diagnosis is difficult. However, the Pressure-Specified Sensory Device (PSSD) may support identifying the earliest stages of intraneural fibro-lipoma when traditional electrodiagnostic testing will not be able to detect a change in peripheral nerve function. Five patients (3 male, 2 female, age 23-53; mean 41 years) with intraneural fibro-lipoma were operated on. Grip strength, pinch strength and sensorial functions were assessed in all patients before surgery and at the end of the follow-up period by PSSD. The patients were followed-up for 7 to 24 months (mean; 12 month). All patient's condition improved dramatically following the operation and all patients had total relief of pain and paresthesia. The decompression of intraneural fibro-lipoma of the nerve with limited excision and epineurotomy without sacrificing the main nerve and its branches is the ideal surgical procedure. We recommend the use of PSSD in the investigation of patients with peripheral nerve compression, and chronic unusual volar forearm and wrist swelling. PSSD is an important tool for pre-operative evaluation and diagnosis of intraneural fibro-lipoma.

  12. Partner choice creates fairness in humans.

    2015-06-07

    Many studies demonstrate that partner choice has played an important role in the evolution of human cooperation, but little work has tested its impact on the evolution of human fairness. In experiments involving divisions of money, people become either over-generous or over-selfish when they are in competition to be chosen as cooperative partners. Hence, it is difficult to see how partner choice could result in the evolution of fair, equal divisions. Here, we show that this puzzle can be solved if we consider the outside options on which partner choice operates. We conduct a behavioural experiment, run agent-based simulations and analyse a game-theoretic model to understand how outside options affect partner choice and fairness. All support the conclusion that partner choice leads to fairness only when individuals have equal outside options. We discuss how this condition has been met in our evolutionary history, and the implications of these findings for our understanding of other aspects of fairness less specific than preferences for equal divisions of resources. © 2015 The Author(s) Published by the Royal Society.

    Intimate partner homicides represent the most severe outcome of intimate partner violence, and constitute more than a quarter (26%) of all homicides in adults over 15 years of age in Southern Denmark. In our experience the victims of partner homicides are primarily women, often from socially disadvantaged families, and that these homicides usually are the result of an impulsive act, with the perpetrator often committing suicide after the act. The aim of this study was to investigate these hypotheses further, and to provide an up-to-date overview of intimate partner homicides in Southern Denmark.

    The Grynfeltt-Lesshaft hernia is a rare posterior abdominal wall defect that allows for the herniation of retro- and intraperitoneal structures through the upper lumbar triangle. While this hernia may initially present as a small asymptomatic bulge, the defect typically enlarges over time and can become symptomatic with potentially serious complications. In order to avoid that outcome, it is advisable to electively repair Grynfeltt hernias in patients without significant contraindications to surgery. Due to the limited number of lumbar hernioplasties performed, there has not been a large study that definitively identifies the best repair technique. It is generally accepted that abdominal hernias such as these should be repaired by tension-free methods. Both laparoscopic and open techniques are described in modern literature with unique advantages and complications for each. We present the case of an unexpected Grynfeltt hernia diagnosed following an attempted lipoma resection. We chose to perform an open repair involving a combination of fascial approximation and dual-layer polypropylene mesh placement. The patient's recovery was uneventful and there has been no evidence of recurrence at over six months. Our goal herein is to increase awareness of upper lumbar hernias and to discuss approaches to their surgical management. PMID:26697256

    Intussusception is a rare cause of obstruction in adults and has a variable, non-specific presentation. Adult intussusception is usually associated with an underlying organic pathology, such as a benign or malignant tumour which acts as the lead point. Prolapse of the lead-point mass through the anal canal is an extremely rare presentation with very few reported cases in the literature. We describe a case of a 67-year-old man who presented with rectal prolapse of a large soft tissue mass. CT of the abdomen and barium enema revealed partial intussusception of an upper sigmoid lipomatous polyp. Examination under anaesthesia was performed and the prolapse reduced. A laparoscopic sigmoid colectomy was planned. The patient subsequently re-presented clinically unwell with a recurrent necrotic prolapsing mass. Laparotomy and sigmoid colectomy was performed and the patient recovered fully. The resected mass was a 7×4.5×4.0 cm necrotic sigmoid lipoma. 2014 BMJ Publishing Group Ltd.

    An important factor affecting preference formation is the context in which that preference decision takes place. The current research examined whether one's preference formed for a previously presented stimulus influences the processing of a subsequent preference decision, henceforth referred to as the preference sequence effect. Using a novel sequential rating/judgment paradigm, the present study demonstrated the presence of a preference sequence effect using artistic photographs and face stimuli: A neutral stimulus was preferred more following a preferable stimulus than a less preferable stimulus. Furthermore, a similar trend was found even when the potential influence of response bias was controlled. These results suggest that an assimilative sequential effect exists even when sequential judgments are made solely based on one's subjective feeling; preference formed for a preceding stimulus modulates preference for a subsequent stimulus. This implies the need for a consideration of trial sequence as a factor creating a psychological context affecting the subsequent preference decisions.

    A 60-years-old man with a right lateral chest wall mass visited our hospital. There was a mass of 50×45 mm on the 5th rib. The mild atypical cells were detected by the percutaneous needle biopsy, and the tumor was resected with the chest wall of which detect was reconstructed with fascia lata and latissimus dorsi muscle cutaneous flap. Pathological diagnosis was lipoma in the serratus anterior muscle. The postoperative course was uneventful without paradoxical respiration and surgical site infection. Since intramuscular lipoma is very rare and is reported to have a risk of recurrence, careful observation is necessary.

The patient was seen following a 2-month history of nonspecific intermittent pain in the right and middle abdomen and weight loss. Sonography revealed ongoing intussusception involving distal ascending and transverse colon. Analysis of the distal intussusception end demonstrated a 3.0 x 2.5 cm echogenic polypoid lesion consistent with a lipoma serving as a lead point. The sonographic diagnosis was confirmed at surgery.

    A hyperlordosis deformity of the lumbar spine is relatively rare, and surgical treatment has not been comprehensively addressed. In this case report, we describe the clinical presentation, surgical treatment, and medium-term follow-up of a patient presenting with a progressive lumbar hyperlordosis deformity after resection of a spinal lipoma associated with spina bifida. The patient was a 20-year-old woman presenting with a progressive hyperlordosis deformity of the lumbar spine associated with significant back pain (visual analog pain score of 89/100 mm), but with no neurological symptoms. The lumbar lordosis (LL), measured on standing lateral view radiographs, was 114°, with a sagittal vertical axis (SVA) of -100 mm. The patient had undergone excision of a lipoma, associated with spina bifida of the lumbar spine, at 7 months of age.She was first evaluated at our hospital at 18 years of age for progressive spinal deformity and lumbago. An in situ fusion, from T5 to S1, using pedicle screws with bone graft obtained from the iliac crest, was performed. Postoperatively, the LL decreased to 93°, and the SVA decreased to -50 mm. The decision to not correct the hyperlordosis deformity fully was intentional. Seven years and 1 month postsurgery, the patient had no limitations in standing and walking and reported a pain score of 8/100 mm; there was no evidence of a loss of correction. Lumbar hyperlordosis after resection of a spinal lipoma associated with spina bifida is rare. Posterior fixation provided an effective treatment in this case. As the lumbar hyperlordosis deformity is often high, correction can be difficult. In this case, although the correction and fusion were performed in situ, there was no progression of either the deformity or the lumbago. Early detection remains an essential component of effective treatment, allowing correction when the spinal deformity is easily reversible.

  3. The value of intraoperative neurophysiological monitoring for microsurgical removal of conus medullaris lipomas: a 12-year retrospective cohort study

    PubMed Central

    2014-01-01

    Background Lipomas in the lower spinal canal can lead to progressive neurological deficits, so they may have to be surgically removed. Intraoperative neurophysiological monitoring serves to minimize the morbidity of the surgical procedure. However, so far there are no evidence-based recommendations which type of monitoring procedure or combination of procedures to choose. Methods The aim of this study was to evaluate the feasibility and value of various intraoperative monitoring techniques: motor and sensory evoked potentials (MEP, SEP), free-running and triggered electromyography (EMG). Thirty cases of spinal lipomas of the Conus medullaris (dorsal Type A: 20.0%; caudal Type B: 33.3%; transitional Type C: 46.7%) were retrospectively evaluated over a 12-year period. Results The patients were mostly pediatric and suffered from persistent pain (73.3%), pareses (56.7%), sensory deficits (43.4%), and/or urogenital dysfunctions (60.0%). SEPs were successfully evoked in 66.7% of cases, MEPs in 86.7% of cases, and EMGs in 100%. MEP alterations correlated with direct mechanical maneuvers in the operating site. SEP changes correlated mostly with physiological events, such as rinsing/cooling of the operating site. Spike-, burst- or tonic train-activity was found in the free-running EMG that occurred only with certain manipulation patterns. Irreversible MEP changes and signal loss in the triggered EMG correlated with post-operative deficits. Conclusions The results of this study showed, that intraoperative monitoring could be considered a helpful tool during lipoma tumor surgery near the Conus medullaris. Most reliable results were obtained from transcranial MEPs, free-running EMGs, and triggered EMGs. That’s why the authors favor a routine set-up consisting of at least these three techniques, as this enables mapping at the beginning of the operation, continuous functional testing during surgery, and prognosis of the post-operative symptomology.

By the analysis of clinical symptoms and of the data in the literature, the AA. are of the opinion that the third nerve deficit they observed is due to a primary malformation of the nerve itself. The importance of radiological findings is emphasized: the stratigraphy showed sphenoid bone defects; the CT allowed the right diagnosis displaying an area of low attenuations values.

    This study investigates the differential functioning of cultural and intellectual openness (the two aspects of Openness to Experience) in relation to social cognitive processes by examining how they influence people's perceptions and interpretations of social information when deciding to initiate working relationships. Using a policy-capturing design, 681 adult participants were asked to rate their similarity to and preference to work with potential work partners characterized by varying nationalities and levels of work-related competence. Multilevel moderated mediation was conducted to simultaneously evaluate whether the indirect effects of potential work partners' characteristics (i.e., nationalities and levels of work-related competence) on work partner preference through perceived similarity were moderated by cultural and intellectual openness. Perceived similarity mediated the relationships between work partner nationality and work-related competence and participants' work partner preferences. Furthermore, the negative indirect effect of work partner nationality on work partner preference via perceived similarity was attenuated by cultural openness, and the positive indirect effect of work partner work-related competence on work partner preference via perceived similarity was strengthened by intellectual openness. Cultural and intellectual openness may have distinct functions that influence how people perceive, evaluate, and appreciate social information when making social judgments. © 2016 Wiley Periodicals, Inc.

    This study examined the role of partners and children for employees' psychological detachment from work during off-job time. Building on boundary theory, we hypothesized that not only employees' own work-home segmentation preference but also their partners' work-home segmentation preference is associated with employees' psychological detachment. In addition, partners' psychological detachment should influence employees' psychological detachment. We hypothesized that the presence of children in the household moderates partners' influence on employees' psychological detachment. Further, we expected both employees' and their partners' psychological detachment to contribute to employees' well-being. Participants were 114 dual-earner couples who responded to Web-based questionnaires. The hypotheses were tested with multilevel analyses, using the actor-partner interdependence model. Results confirmed our hypotheses. Employees' and their partners' work-home segmentation preferences were associated with employees' psychological detachment. The presence of children moderated the relation between partners' work-home segmentation preference and employees' psychological detachment. The relation was weaker when there were children in the household. Moreover, employees' and their partners' psychological detachment were positively associated. Again, the relation was weaker when there were children in the household. Finally, both employees' and their partners' psychological detachment contributed to employees' well-being.

    We have investigated the morphology, cytogenetics, and the fraction of mtDNA with the tRNA(Lys) A-->G(8344) mutation in three lipomas in a carrier of this mutation. The son of the patient had myoclonus epilepsy and ragged-red fibers syndrome. The fraction of mtDNA with the tRNA(Lys) mutation varied between 62% and 80% in cultured skin fibroblasts, lymphocytes, normal adipose tissue, and muscle. In the three lipomas the mean fraction of mutated mtDNA was 90%, 94%, and 94%. Ultrastructural examination of the lipomas revealed numerous mitochondria with changes such as electron-dense inclusions in some adipocytes. When considered cytogenetically, the lipomas were characterized by a mixture of karyotypically abnormal and normal cells. An identical del(6)(q24) was found in two tumors. The fraction of mutated mtDNA in cultured lipoma cells was the same as in the lipoma in situ, indicating that the cultured cells were representative of the primary tumor. These findings indicate that the lipomas have originated with a grossly normal stem line and subsequently have developed the 6q deletion. We conclude that the lipomas represent clonal growth of adipocytes with a high content of mtDNA with the tRNA(Lys) mutation. The tRNA(Lys) mutation may be either the direct or the indirect cause of pertubation of the maturation process of the adipocytes, leading to an increased risk of lipoma formation.

    2014-11-01

    Assortative mating for adiposity, whereby levels of adiposity in romantic partners tend to be positively correlated, has implications for population health due to the combined effects of partners' levels of adiposity on fertility and/or offspring health. Although assortative preferences for cues of adiposity, whereby leaner people are inherently more attracted to leaner individuals, have been proposed as a factor in assortative mating for adiposity, there have been no direct tests of this issue. Because of this, and because of recent work suggesting that facial cues of adiposity convey information about others' health that may be particularly important for mate preferences, we tested the contribution of assortative preferences for facial cues of adiposity to assortative mating for adiposity (assessed from body mass index, BMI) in a sample of romantic couples. Romantic partners' BMIs were positively correlated and this correlation was not due to the effects of age or relationship duration. However, although men and women with leaner partners showed stronger preferences for cues of low levels of adiposity, controlling for these preferences did not weaken the correlation between partners' BMIs. Indeed, own BMI and preferences were uncorrelated. These results suggest that assortative preferences for facial cues of adiposity contribute little (if at all) to assortative mating for adiposity.

  19. Ileocolic Intussusception Caused by a Giant Ulcerating Lipoma of Bauhin's Valve: an Unusual Cause of Intestinal Obstruction in the Adult.

    PubMed

    Gys, B; Haenen, F; Gys, T

    2015-04-01

    We report a case of intestinal obstruction in a 73-year-old woman caused by ileocolic intussusception. The underlying cause was a giant submucosal ulcerating lipoma (6 × 3.3 × 3.8 cm) extending from the superior mucosal lip of Bauhin's valve. Abdominal ultrasonography showed a pathognomonic target-like mass appearing as multiple concentric rings. CT scan confirmed the diagnosis. Because of apparent obstruction, a laparotomy with right hemicolectomy and ileocolic anastomosis was performed. Lipomas most frequently occur in the cecum and ascending colon where they represent the most common submucosal mesenchymal tumor. They typically occur in elderly women with an incidence that varies from 0.15 to 0.56 %. Pain, rectal bleeding, and obstruction are typical symptoms. When faced with an intussusception in children, reduction with air per rectum can be performed. In adults, however, malignant cell spreading and seeding is of big concern. Since approximately 20-50 % of all underlying causes are malignant, explorative surgery is favored in adults.

    O’Doherty, Jim; Clauss, Ralf; Scuffham, James; Khan, Aman; Petitguillaume, Alice; Desbrée, Aurélie

    2014-05-15

    Purpose: Lipoma arborescens (LA) is a benign intra-articular lipomatous proliferation of the synovial membrane. This extremely rare condition has previously been treated by intra-articular{sup 90}Y radiosynoviorthesis but dosimetry literature on this form of radionuclide therapy is nonexistent. The authors detail methodology for successful treatment of LA and provide for the first time estimates of radiation dosimetry. The authors also analyze the biodistribution of the radiopharmaceutical over the course of the patient's treatment through sequential imaging. Methods: A patient with bilateral LA underwent intracavity injection of{sup 90}Y citrate colloid to the right and left knee joint spaces (181 and 198 MBq, respectively). SPECT/CT datasets were acquired over 9 days to quantify the biodistribution and kinetics of the radiopharmaceutical. Radiation dosimetry was performed using the MIRD schema (through OLINDA software), a custom voxel-based method, and a direct Monte Carlo calculation (OEDIPE). Results: Follow-up MRI showed marked reduction in LA size in both knees. Mean absorbed doses to the LA were 21.2 ± 0.8 and 42.9 ± 2.3 Gy using OLINDA, 8.1 ± 0.3 and 16.7 ± 0.5 Gy using voxel based methodology, and 8.2 ± 0.3 and 15.7 ± 0.5 Gy for OEDIPE in the right and left LA, respectively. Distribution of the radiopharmaceutical within the joint space alters over the imaging period, with less than 1% of the remaining activity having moved posteriorly in the knee cavity. No uptake was detected outside of the joint space after assessment with whole-body scintigraphy. Conclusions: An activity of approximately 185 MBq successfully relieved clinical symptoms of LA. There was good correlation between direct Monte Carlo and voxel based techniques, but OLINDA was shown to overestimate the absorbed dose to the tumor. Accurate dosimetry may help select an activity more tailored to the specific size and location of the LA.

    The authors studied partners of 18 transvestites who sought consultation because of their disorder. They found that all of these women were moral masochists and that all tolerated the self-centered, obsessive-compulsive behavior of their transvestic spouses. Many of these women had experienced multiple losses and poor parenting, and their transvestic partners fulfilled their dependency needs. The authors recommend supportive and insight-oriented therapy for such women who, in order to stay with a transvestic man, sacrifice their own self-esteem and desire to engage in a mutual relationship.

    In a recent study, we demonstrated that rats prefer mutual rewards in a Prosocial Choice Task. Here, employing the same task, we show that the integrity of basolateral amygdala was necessary for the expression of mutual reward preferences. Actor rats received bilateral excitotoxic (n=12) or sham lesions (n=10) targeting the basolateral amygdala and were subsequently tested in a Prosocial Choice Task where they could decide between rewarding ("Both Reward") or not rewarding a partner rat ("Own Reward"), either choice yielding identical reward to the actors themselves. To manipulate the social context and control for secondary reinforcement sources, actor rats were paired with either a partner rat (partner condition) or with an inanimate rat toy (toy condition). Sham-operated animals revealed a significant preference for the Both-Reward-option in the partner condition, but not in the toy condition. Amygdala-lesioned animals exhibited significantly lower Both-Reward preferences than the sham group in the partner but not in the toy condition, suggesting that basolateral amygdala was required for the expression of mutual reward preferences. Critically, in a reward magnitude discrimination task in the same experimental setup, both sham-operated and amygdala-lesioned animals preferred large over small rewards, suggesting that amygdala lesion effects were restricted to decision making in social contexts, leaving self-oriented behavior unaffected.

  11. Predictability of Conversation Partners

    2011-08-01

    Recent developments in sensing technologies have enabled us to examine the nature of human social behavior in greater detail. By applying an information-theoretic method to the spatiotemporal data of cell-phone locations, [C. Song , ScienceSCIEAS0036-8075 327, 1018 (2010)] found that human mobility patterns are remarkably predictable. Inspired by their work, we address a similar predictability question in a different kind of human social activity: conversation events. The predictability in the sequence of one’s conversation partners is defined as the degree to which one’s next conversation partner can be predicted given the current partner. We quantify this predictability by using the mutual information. We examine the predictability of conversation events for each individual using the longitudinal data of face-to-face interactions collected from two company offices in Japan. Each subject wears a name tag equipped with an infrared sensor node, and conversation events are marked when signals are exchanged between sensor nodes in close proximity. We find that the conversation events are predictable to a certain extent; knowing the current partner decreases the uncertainty about the next partner by 28.4% on average. Much of the predictability is explained by long-tailed distributions of interevent intervals. However, a predictability also exists in the data, apart from the contribution of their long-tailed nature. In addition, an individual’s predictability is correlated with the position of the individual in the static social network derived from the data. Individuals confined in a community—in the sense of an abundance of surrounding triangles—tend to have low predictability, and those bridging different communities tend to have high predictability.

    2016-08-01

    Drawing on the logic of the relational turbulence model, this study examined the ways in which romantic partners facilitate and interfere with individuals' weight loss goals. Participants (N = 122) described the ways in which their romantic partner had recently helped or hindered their weight loss at four times over the course of 2 months. We conducted a content analysis of responses to identify themes of partner facilitation (Research Question 1 [RQ1]) and partner interference (RQ2) in individuals' weight loss goals. Results revealed seven themes of partner facilitation: (a) partner enabling diet, (b) motivation and encouragement, (c) emotional support and positive reinforcement, (d) exercising together, (e) partner enabling exercise, (f) dieting together, and (g) relationship influence and priorities. Four themes of partner interference emerged in the data: (a) inability to plan for healthy meals, (b) inability to control the food environment, (c) preventing or discouraging exercise, and (d) emotional or relational discouragement.

    1993-10-15

    An 8-month-old neutered male Manx-type cat was evaluated because of clear fluid that had been draining from a skin mass dorsocaudal to the sacrum for 1 week. Neurologically, the cat had poor postural reactions and poor withdrawal reflexes in the hind limbs. Ultrasonography of the dorsal sacral area revealed a 3-cm-long hypoechoic tract extending from the skin mass cranioventrally to the area of the sacrum. The tract appeared to contain a circular mass. Results of myelography and computed tomography helped to confirm the diagnosis of a meningocutaneous tract containing a mass. Surgical exploration was performed and the tract was excised. Histologic changes were similar to those in human beings with tethered spinal cord syndrome and an intradural lumbosacral lipoma. Surgery was indicated in this cat to prevent progression of neurologic signs associated with tethered cord syndrome and to prevent problems associated with loss of CSF through a fistulated meningocele.

  19. Spontaneous recurrent hemarthrosis of the knee joint in elderly patients with osteoarthritis: an infrequent presentation of synovial lipoma arborescens.

    PubMed

    Ji, Jong-Hun; Lee, Yeon-Soo; Shafi, Mohamed

    2010-10-01

    Synovial lipoma arborescens (SLA) is a rare, benign, fat-containing synovial proliferative lesion that is typically known to affect the knee joint in adults, although it has also been described in other joints. SLA usually presents as a painless swelling and recurrent joint effusion, and the laboratory test results, including aspirated synovial fluid, are usually normal. We present here two cases of SLA of the knee, which presented as spontaneous recurrent hemarthroses in elderly patients with osteoarthritis (OA) with bloody aspirated synovial fluid. Magnetic resonance imaging (MRI) and arthroscopic synovectomy suggested the diagnosis of SLA; the histopathologic examination confirmed the diagnosis. One year later, both patients remain symptom-free and report no new episodes of hemarthrosis. We postulate that SLA should be included in the differential diagnosis of patients with recurrent joint effusions with hemarthrosis in elderly patients with OA. The clinical presentation, MRI findings, and treatment of SLA are described, and the entity is briefly reviewed.

  20. Preference Versus Choice in Online Dating.

    2017-03-01

    This study explores factors that influence matches of online dating participants' stated preference for particular characteristics in a potential partner and compares these with the characteristics of the online daters actually contacted. The nature of online dating facilitates exploration of the differences between stated preference and actual choice by participants, as online daters willingly provide a range of demographics on their ideal partner. Using data from the Australian dating website RSVP, we analyze 219,013 contact decisions. We conduct a multivariate analysis using the number of matched variables between the participants' stated preference and the characteristics of the individuals contacted. We find that factors such as a person's age, their education level, and a more social personality all increase the number of factors they choose in a potential partner that match their original stated preference. Males (relative to females) appear to match fewer characteristics when contacting potential love interests. Conversely, age interaction effects demonstrate that males in their late 60's are increasingly more selective (than females) regarding who they contact. An understanding of how technology (the Internet) is impacting human mating patterns and the psychology behind the participants informs the wider social science of human behavior in large-scale decision settings.

  1. Expression of HMGI-C and HMGI(Y) in ordinary lipoma and atypical lipomatous tumors: immunohistochemical reactivity correlates with karyotypic alterations.

    The high mobility group proteins (HMGs) are a class of low molecular weight, nonhistone, nuclear proteins that bind DNA and function as transcription cofactors. This class includes the HMGI family members HMGI-C and HMGI(Y). Both are not significantly expressed in differentiated adult tissues, including fat, but their expression is induced in proliferating and transformed cells. Their involvement in the development of lipomatous tumors has been recently demonstrated for HMGI-C, which is encoded by a gene located at 12q15, the chromosomal segment often rearranged in ordinary lipomas. The same chromosomal segment is consistently amplified in the ring and giant marker chromosomes of atypical lipomatous tumors (ALTs), a term used to designate tumors previously labeled as well differentiated liposarcomas or atypical lipomas. The involvement of HMGI(Y) is strongly suspected as the gene coding for HMGI(Y) is located at 6p21, a chromosomal segment rearranged in a subset of ordinary lipomas. HMGI-C or HMGI(Y) protein expression was analyzed immunohistochemically in a group of 39 well differentiated adipose neoplasms (19 lipomas and 20 ALTs) of known karyotype using polyclonal antibodies raised against a recombinant protein (HMGI-C) and against a synthetic peptide (HMGI(Y)). The results of this study demonstrate that HMGI proteins are commonly expressed in well differentiated adipose neoplasms. Seventeen of twenty ALTS (85.0%), all of which had ring or giant marker chromosomes with amplification of 12q13-15, strongly expressed HMGI-C. HMGI-C expression was detected in 7 of 11 ordinary lipomas (63.6%) with alterations at 12q14-15 and in one case with an abnormal karyotype that included double minute chromosomes. HMGI-C immunoreactivity correlates with 12q13-15 chromosomal alterations (P = 0.001). HMGI(Y) reactivity was demonstrated in only two ordinary lipomas: one with 6p21 rearrangement and one with normal karyotype. No significant HMGI(Y) expression was found in the ALT

    2009-01-01

    Revealed preferences are tastes that rationalize an economic agent’s observed actions. Normative preferences represent the agent’s actual interests. It sometimes makes sense to assume that revealed preferences are identical to normative preferences. But there are many cases where this assumption is violated. We identify five factors that increase the likelihood of a disparity between revealed preferences and normative preferences: passive choice, complexity, limited personal experience, third-party marketing, and intertemporal choice. We then discuss six approaches that jointly contribute to the identification of normative preferences: structural estimation, active decisions, asymptotic choice, aggregated revealed preferences, reported preferences, and informed preferences. Each of these approaches uses consumer behavior to infer some property of normative preferences without equating revealed and normative preferences. We illustrate these issues with evidence from savings and investment outcomes. PMID:24761048

  7. Time perspective and social preference in older and younger adults: Effects of self-regulatory fatigue.

    PubMed

    2016-09-01

    Socioemotional selectivity theory predicts that when perceived time in life is limited, people will prefer emotionally close social partners over less emotionally rewarding partners. Regulating social choices with regard to time perspective can make the best use of time with regard to well-being. However, doing so may depend on the self-regulatory capacity of the individual. Two studies, 1 with younger adults (N = 101) and 1 with younger (N = 42) and older (N = 39) adults, experimentally tested the effects of time perspective and self-regulatory fatigue on preferences for emotionally close partners and knowledgeable partners. In both studies and across younger and older adults, when self-regulatory fatigue was low, the perception of limited time resulted in a greater preference for close social partners relative to knowledgeable social partners. However, this shift was eliminated by self-regulatory fatigue. In Study 2, when fatigued, younger adults preferred close social partners to knowledgeable partners across time perspectives; older adults preferred close and knowledgeable partners more equally across time perspectives. These findings have implications for social decision-making and satisfaction among people who experience chronic self-regulatory fatigue. They also contradict previous suggestions that only younger adults are susceptible to self-regulatory fatigue. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

    Surgery and anesthesiology have always been closely connected. Within the increasing complexity of therapies and technical capabilities both subjects overlap in certain areas. This article deals with the question whether anesthesiology is acting as a partner or competitor in the cooperation with the various operative specialties. In several studies it has been shown that the outcome of surgical patients can be improved by communication and interaction with anesthesiology and that forming multidisciplinary teams will be highly beneficial for patients in intensive care units.

    2012-12-01

    To examine the role of sexual partners in adolescent mothers' use of non-coital dependent contraceptive methods in the postpartum period. 40 African American adolescent mothers completed surveys and qualitative interviews during the first postpartum year as part of a larger longitudinal study in Chicago, Illinois. Themes related to contraception and sexual partners were analyzed. Adolescent mothers' reports of partners' roles in the use of non-coital dependent contraceptive methods (i.e., oral contraceptives, intrauterine contraception, and depot medroxyprogesterone acetate). Partners largely supported the use of non-coital dependent contraceptive methods, yet mechanisms of support varied greatly, from advocating for specific methods to facilitating participants' continuation of their chosen method. Unsupportive partners either expressed concerns about the safety and side effects of specific methods or desired another child in the near future. Participants valued these preferences to different degrees when making their contraceptive decisions. Partners of adolescent mothers play varying roles in postpartum contraceptive decisions. They thus have the potential both to inhibit and to facilitate the use of non-coital dependent contraception. Quantitative research is needed to further evaluate how partner attitudes and support behaviors, among other factors, affect contraceptive initiation and continuation among adolescent mothers.

    The treatment of infantile fibrosarcoma has traditionally been wide resection. Chemotherapy has been investigated as an adjuvant and primary treatment in cases in which surgery would cause unacceptable morbidity. Recurrences normally occur within a year of completion of the chemotherapy and display the same histology. We present a child with an infantile fibrosarcoma of the elbow, successfully treated with chemotherapy alone, who developed a calcifying aponeurotic fibroma and a spindle cell/pleomorphic lipoma at the tumor site 12 years later.

  12. Evolutionary preferences for physical formidability in leaders.

    PubMed

    Murray, Gregg R

    2014-01-01

    This research uses evolutionary theory to evaluate followers' preferences for physically formidable leaders and to identify conditions that stimulate those preferences. It employs a population-based survey experiment (N ≥ 760), which offers the advantages to internal validity of experiments and external validity of a highly heterogeneous sample drawn from a nationally representative subject pool. The theoretical argument proffered here is followers tend to prefer leaders with greater physical formidability because of evolutionary adaptations derived from humans' violent ancestral environment. In this environment, individuals who allied with and ultimately followed physically powerful partners were more likely to acquire and retain important resources necessary for survival and reproduction because the presence of the physically powerful partner cued opponents to avoid a challenge for the resources or risk a costly confrontation. This argument suggests and the results indicate that threatening (war) and nonthreatening (peace, cooperation, and control) stimuli differentially motivate preferences for physically formidable leaders. In particular, the findings suggest threatening conditions lead to preferences for leaders with more powerful physical attributes, both anthropometric (i.e., weight, height, and body mass index) and perceptual (i.e., attributes of being "physically imposing or intimidating" and "physically strong"). Overall, this research offers a theoretical framework from which to understand this otherwise seemingly irrational phenomenon. Further, it advances the emerging but long-neglected investigation of biological effects on political behavior and has implications for a fundamental process in democratic society, leader selection.

  13. An unusual and spectacular case of spindle cell lipoma of the posterior neck invading the spinal cervical canal and posterior cranial fossa.

    2011-11-01

    The authors describe the first case of spindle cell lipoma of the posterior neck invading the upper cervical spinal canal and the posterior cranial fossa. Spindle cell lipoma is an extremely rare variant of benign lipoma. It usually occurs as a solitary subcutaneous well-circumscribed lesion in the posterior neck or shoulders of adult men. Local aggressiveness is unusual. This 61-year-old man presented with an increased left cerebellar syndrome and headaches. He also had a posterior neck tumefaction, which had been known about for a long time. Computed tomography and MR imaging studies revealed a voluminous mass extending to the upper cervical canal and posterior cranial fossa and eroding the neighboring bones. The lesion was well delimited, and contrast enhancement was intense and heterogeneous. The tumor, which had initially developed under the muscles of the posterior neck, was totally resected. Histological assessment revealed numerous fat cells with spindle cells secreting collagen. The large size of the tumor and the submuscular location, bone erosion, and compression of the CNS were unusual in this rare subtype of benign adipose tumor. Its presentation could simulate a sarcoma.

    2016-01-01

    The authors present a unique case of intracranial lipoma in the interpeduncular cistern associated with proximal P1 segment fenestration. This patient is a 20-year-old male with extensive psychiatric history and complaints of recent auditory hallucinations. Cranial magnetic resonance imaging (MRI) (T1, T2, and FLAIR) showed a hyperintense lesion in the left aspect of interpeduncular cistern with a prominent flow void within the hyperintense lesion suggestive of a combined vascular–lipomatous lesion. Computed tomography (CT) angiography showed a high-riding large tortuous P1 segment on the left side with proximal fenestration, the ectatic posteromedial limb harboring a fusiform dilated segment. Since there are anecdotal cases of cerebral aneurysms associated with intracranial lipomas, a conventional angiography was done, which confirmed a proximal left P1 fenestration and a fusiform-dilated segment, and no aneurysm. There are few cases of hallucinations associated with a vascular midbrain pathology reported in literature, but hallucinations associated with a combination of lipoma and arterial ectasia have never been reported. This article not only demonstrates the MRI and angiographic appearance of this rare lipomatous lesion but also highlights this unique association and significance of auditory hallucinations as a clinical presentation, akin to peduncular hallucinosis.

    2012-01-01

    Do humans prefer the self even over their favorite other person? This question has pervaded philosophy and social-behavioral sciences. Psychology’s distinction between explicit and implicit preferences calls for a two-tiered solution. Our evolutionarily-based Dissociative Self-Preference Model offers two hypotheses. Other-preferences prevail at an explicit level, because they convey caring for others, which strengthens interpersonal bonds–a major evolutionary advantage. Self-preferences, however, prevail at an implicit level, because they facilitate self-serving automatic behavior, which favors the self in life-or-die situations–also a major evolutionary advantage. We examined the data of 1,519 participants, who completed an explicit measure and one of five implicit measures of preferences for self versus favorite other. The results were consistent with the Dissociative Self-Preference Model. Explicitly, participants preferred their favorite other over the self. Implicitly, however, they preferred the self over their favorite other (be it their child, romantic partner, or best friend). Results are discussed in relation to evolutionary theorizing on self-deception. PMID:22848605

    This study examines the impact of fear of past abusive partner(s) on posttraumatic stress among 212 community-recruited women currently exposed to intimate partner violence (IPV). The path analysis model tested explained 60% of the variation in IPV-related posttraumatic stress. Findings revealed that fear of past abusive partner(s) was uniquely associated with the severity of current posttraumatic stress symptoms over and above the impact of current IPV or childhood abuse and neglect. Future research should continue examining women's subjective emotional experience of past and current victimization so as to further inform both clinical practice and intervention planning.

    The way individuals pair to produce reproductive units is a major factor determining evolution. This process is complex because it is determined not only by individual mating preferences, but also by numerous other factors such as competition between mates. Consequently, preferred and actual characteristics of mates obtained should differ, but this has rarely been addressed. We simultaneously measured mating preferences for stature, body mass, and body mass index, and recorded corresponding actual partner's characteristics for 116 human couples from France. Results show that preferred and actual partner's characteristics differ for male judges, but not for females. In addition, while the correlation between all preferred and actual partner's characteristics appeared to be weak for female judges, it was strong for males: while men prefer women slimmer than their actual partner, those who prefer the slimmest women also have partners who are slimmer than average. This study therefore suggests that the influences of preferences on pair formation can be sex-specific. It also illustrates that this process can lead to unexpected results on the real influences of mating preferences: traits considered as highly influencing attractiveness do not necessarily have a strong influence on the actual pairing, the reverse being also possible.

    The heterogeneity of domestic violent men has long been established. However, research has failed to examine this phenomenon among men committing the most severe form of domestic violence. This study aims to use a multidimensional approach to empirically construct a classification system of men who are incarcerated for the murder of their female partner based on the Holtzworth-Munroe and Stuart (1994) typology. Ninety men who had been convicted and imprisoned for the murder of their female partner or spouse in England were identified from two prison samples. A content dictionary defining offense and offender characteristics associated with two dimensions of psychopathology and criminality was developed. These variables were extracted from institutional records via content analysis and analyzed for thematic structure using multidimensional scaling procedures. The resultant framework classified 80% (n = 72) of the sample into three subgroups of men characterized by (a) low criminality/low psychopathology (15%), (b) moderate-high criminality/ high psychopathology (36%), and (c) high criminality/low-moderate psychopathology (49%). The latter two groups are akin to Holtzworth-Munroe and Stuart's (1994) generally violent/antisocial and dysphoric/borderline offender, respectively. The implications for intervention, developing consensus in research methodology across the field, and examining typologies of domestic violent men prospectively are discussed.

    Within the class of memory-one strategies for the iterated Prisoner's Dilemma, we characterize partner strategies, competitive strategies and zero-determinant strategies. If a player uses a partner strategy, both players can fairly share the social optimum; but a co-player preferring an unfair solution will be penalized by obtaining a reduced payoff. A player using a competitive strategy never obtains less than the co-player. A player using a zero-determinant strategy unilaterally enforces a linear relation between the two players' payoffs. These properties hold for every strategy used by the co-player, whether memory-one or not. PMID:26339123

    2014-07-01

    Using a sample of Deaf female undergraduate students, the current study sought to investigate the prevalence, correlates, and characteristics of intimate partner violence victimization in hearing-Deaf and Deaf-Deaf relationships. Initial results suggest that similarities in hearing status and communication preference are associated with increased levels of negotiation within these relationships. However, compatibility in these areas did not co-occur with significant decreases in physical, psychological, or sexual partner violence. Recommendations for future research as well as implications for clinical and educational practice are outlined.

  6. Men's strategic preferences for femininity in female faces.

    2014-08-01

    Several evolutionarily relevant sources of individual differences in face preference have been documented for women. Here, we examine three such sources of individual variation in men's preference for female facial femininity: term of relationship, partnership status and self-perceived attractiveness. We show that men prefer more feminine female faces when rating for a short-term relationship and when they have a partner (Study 1). These variables were found to interact in a follow-up study (Study 2). Men who thought themselves attractive also preferred more feminized female faces for short-term relationships than men who thought themselves less attractive (Study 1 and Study 2). In women, similar findings for masculine preferences in male faces have been interpreted as adaptive. In men, such preferences potentially reflect that attractive males are able to compete for high-quality female partners in short-term contexts. When a man has secured a mate, the potential cost of being discovered may increase his choosiness regarding short-term partners relative to unpartnered men, who can better increase their short-term mating success by relaxing their standards. Such potentially strategic preferences imply that men also face trade-offs when choosing relatively masculine or feminine faced partners. In line with a trade-off, women with feminine faces were seen as more likely to be unfaithful and more likely to pursue short-term relationships (Study 3), suggesting that risk of cuckoldry is one factor that may limit men's preferences for femininity in women and could additionally lead to preferences for femininity in short-term mates.

    The process of gender transition has varying effects on various aspects of sexuality. The purpose of this study was to investigate the effects of transitioning on transgender persons' sexual preferences and partnerships. Data were collected through an anonymous online survey. Questions focused on timing of gender transition in relation to change in sexual preference. Transgender individuals have a variety of sexual partners, predominantly cisgender, and may change sexual preference when they transition. Transitioning can be associated with having no primary sexual partner, despite past sexual partnerships. Length of time between identifying as transgender and starting the transition might be associated with changing sexual partner preference, particularly in transgender women. The emerging trends of sexual partnerships and changing sexual preferences related to the transition in this study warrant further investigation. These data provide more understanding of the relationship between transitioning and sexual preferences and partnerships.

    This study analyzed whether police attitudes toward policing partner violence against women corresponded with different psychosocial profiles. Two attitudes toward policing partner violence were considered-one reflecting a general preference for a conditional law enforcement (depending on the willingness of the victim to press charges against the offender) and the other reflecting a general preference for unconditional law enforcement (regardless of the victim's willingness to press charges against the offender). Results from a sample of 378 police officers showed that those police officers who expressed a general preference for unconditional law enforcement scored higher in other-oriented empathy, were less sexist, tended to perceive the same incidents of partner violence as more serious, and felt more personally responsible, as compared to the group of police officers who expressed a preference for a conditional law enforcement approach. Implications for police education are considered.

    Study Objective To examine the role of sexual partners in adolescent mothers’ use of non-coital dependent contraceptive methods in the postpartum period. Design/Setting/Participants 40 African American adolescent mothers completed surveys and qualitative interviews during the first postpartum year as part of a larger longitudinal study in Chicago, Illinois. Themes related to contraception and sexual partners were analyzed. Main Outcome Measures Adolescent mothers’ reports of partners’ roles in the use of non-coital dependent contraceptive methods (i.e., oral contraceptives, intrauterine contraception, and depot medroxyprogesterone acetate). Results Partners largely supported the use of non-coital dependent contraceptive methods, yet mechanisms of support varied greatly, from advocating for specific methods to facilitating participants’ continuation of their chosen method. Unsupportive partners either expressed concerns about the safety and side effects of specific methods or desired another child in the near future. Participants valued these preferences to different degrees when making their contraceptive decisions. Conclusions Partners of adolescent mothers play varying roles in postpartum contraceptive decisions. They thus have the potential to both inhibit and facilitate the use of non-coital dependent contraception. Quantitative research is needed to further evaluate how partner attitudes and support behaviors, among other factors, affect contraceptive initiation and continuation among adolescent mothers.

  12. Compound double ileoileal and ileocecocolic intussusception caused by lipoma of the ileum in an adult patient: A case report

    PubMed Central

    2011-01-01

    Introduction The initial diagnosis of intussusception in adults very often can be missed and cause delayed treatment and possible serious complications. We report the case of an adult patient with complicated double ileoileal and ileocecocolic intussusception. Case presentation A 46-year-old Caucasian man was transferred from the gastroenterology service to the abdominal surgery service with severe abdominal pain, nausea, and vomiting. An abdominal ultrasound, barium enema, and abdominal computed tomography scan revealed an intraluminal obstruction of his ascending colon. Plain abdominal X-rays showed diffuse air-fluid levels in his small intestine. A double ileoileal and ileocecocolic intussusception was found during an emergent laparotomy. A right hemicolectomy, including resection of a long segment of his ileum, was performed. The postoperative period was complicated by acute renal failure, shock liver, and pulmonary thromboembolism. Our patient was discharged from the hospital after 30 days. An anatomical pathology examination revealed a lipoma of his ileum. Conclusions Intussusception in adults requires early surgical resection regardless of the nature of the initial cause. Delayed treatment can cause very serious complications. PMID:21910876

    A 53-year old man presented with seven months history of progressive weakness of extension of the digits and the thumb of the left hand. The wrist extension was normal and sensations were also intact. The patient had also been noticing a progressively enlarging lump on the lower anterolateral aspect of the left antecubital fossa for the last three months. Physical examination andelectro diagnostic studies revealed motor deficit along the posterior interosseous nerve (PIN) distribution with preservation of sensations. Also a soft tissue solitary lump (measuring 6×5 cm in its greatest dimensions) was palpable in the left antecubital fossa. The magnetic resonance imaging (MRI) of the forearm revealed a well-defined, non-enhancing, homogenous, fat intensity lesion in the left antecubital fossa, attached to the proximal radius. The patient underwent surgical excision of the lump with decompression of the PIN in the radial tunnel. Histopathology confirmed the diagnosis of parosteal lipoma. Although the diagnosis was elusive at the very outset, yet prudent clinical judgment, appropriate ancillary investigations and timely surgical intervention resulted in optimal functional recovery of the hand drop. There was complete motor recovery at 4-months follow up with no recurrence of the lipomaafter one year. PMID:28289621

    Selective breeding alcohol-preferring (P) and alcohol-nonpreferring (NP) rats showed a strong preference for the sucrose solutions, whereas P rats intake greater amounts than NP rats. The aim of this study was the estimation of selectively bred ethanol-preferring (WHP - Warsaw High Preferring) and ethanol-nonpreferring (WLP - Warsaw Low Preferring) rats for their preference for various tastes. The oral drinking of the following substances was studied at a range of concentrations: sucrose (0.5-64.0 g/100 ml), NaCl (0.025-3.2 g/100 ml), citric acid (0.008-2.048 g/l), and sucrose octaacetate (0.002-0.512 g/l) solutions. Separate groups of 7-8 rats from each line were investigated of each of the four tastes. The investigated solutions were presented continuously keeping water and food always available. Concentrations of the various flavors were doubled every 48 h. Rats from WHP and WLP lines clearly revealed the preference for the sucrose solution and the highest preference was at the 4.0 and 8.0 g/100ml sucrose concentration. Similar to sucrose, both lines exposed strong preference for the NaCl solution and this preference enhanced together with the increase of the NaCl concentration. Nevertheless their preference for the NaCl solutions decreased when the concentration of NaCl reached 1.600 g/100 ml. Both lines of rats did not differ in citric acid or sucrose octaacetate intake at any of the concentrations studied. Selective breeding of rats (WHP) for high and rats (WLP) for low ethanol drinking is favorably correlated with the drinking of sweet and salty solutions and negatively correlated with the consumption of sour and bitter tastes.

    Lipomas are the most common soft tissue tumors in adults. They often carry chromosome aberrations involving 12q13~15 leading to rearrangements of the HMGA2 gene in 12q14.3, with breakpoints occurring within or outside of the gene. Here, we present eleven lipomas and one osteochondrolipoma with a novel recurrent chromosome aberration, t(12;18)(q14~15;q12~21). Molecular studies on eight of the tumors showed that full-length HMGA2 transcript was expressed in three and a chimeric HMGA2 transcript in five of them. In three lipomas and in the osteochondrolipoma, exons 1-3 of HMGA2 were fused to a sequence of SETBP1 on 18q12.3 or an intragenic sequence from 18q12.3 circa 10 kbp distal to SETBP1. In another lipoma, exons 1-4 of HMGA2 were fused to an intronic sequence of GRIP1 which maps to chromosome band 12q14.3, distal to HMGA2. The ensuing HMGA2 fusion transcripts code for putative proteins which contain amino acid residues of HMGA2 corresponding to exons 1-3 (or exons 1-4 in one case) followed by amino acid residues corresponding to the fused sequences. Thus, the pattern is similar to the rearrangements of HMGA2 found in other lipomas, i.e., disruption of the HMGA2 locus leaves intact exons 1-3 which encode the AT-hooks domains and separates them from the 3'-terminal part of the gene. The fact that the examined osteochondrolipoma had a t(12;18) and a HMGA2-SETBP1 fusion identical to the findings in the much more common ordinary lipomas, underscores the close developmental relationship between the two tumor types.

    To describe the incidence, assessment, and management of intimate partner violence (IPV) from a cultural perspective emphasizing the values, strengths, and health care needs of African-American women. Review of the published scientific literature, U.S. Bureau of Justice Statistics and the National Crime Victimization Survey (NCVS) supplemented with hypothetical cases. Violence is a social and public health emergency affecting over 10% of the population during their lives and 22% of women who are physically assaulted by an intimate. Roughly 3 million to 4.4 million women report being battered annually, although this is a low estimate. Neither gender nor age nor sexual orientation protects one from IPV. Violent crime causes 2.2 million known injuries with a huge cost in hospital days and other expenses. Women often hesitate to report violence; health care professionals detect as few as 5% of battered women. Women suffer for months and years before accurate diagnosis. Clinicians need to be vigilant in case finding, education, prevention, and treatment. Cultural differences in values and beliefs, and behavioral norms influence evaluation, treatment, and referral.

    2012-01-01

    We study the standard SIS model of epidemic spreading on networks where individuals have a fluctuating number of connections around a preferred degree . Using very simple rules for forming such preferred degree networks, we find some unusual statistical properties not found in familiar Erdös-Rényi or scale free networks. By letting depend on the fraction of infected individuals, we model the behavioral changes in response to how the extent of the epidemic is perceived. In our models, the behavioral adaptations can be either ‘blind’ or ‘selective’ – depending on whether a node adapts by cutting or adding links to randomly chosen partners or selectively, based on the state of the partner. For a frozen preferred network, we find that the infection threshold follows the heterogeneous mean field result and the phase diagram matches the predictions of the annealed adjacency matrix (AAM) approach. With ‘blind’ adaptations, although the epidemic threshold remains unchanged, the infection level is substantially affected, depending on the details of the adaptation. The ‘selective’ adaptive SIS models are most interesting. Both the threshold and the level of infection changes, controlled not only by how the adaptations are implemented but also how often the nodes cut/add links (compared to the time scales of the epidemic spreading). A simple mean field theory is presented for the selective adaptations which capture the qualitative and some of the quantitative features of the infection phase diagram. PMID:23189133

  9. Rb1 and Pten Co-Deletion in Osteoblast Precursor Cells Causes Rapid Lipoma Formation in Mice

    The Rb and Pten tumor suppressor genes are important regulators of bone development and both are frequently mutated in the bone cancer osteosarcoma (OS). To determine if Rb1 and Pten synergize as tumor suppressor genes for osteosarcoma, we co-deleted them in osteoprogenitor cells. Surprisingly, we observed rapid development of adipogenic but not osteosarcoma tumors in the ΔRb1/Pten mice. ΔPten solo deleted mice also developed lipoma tumors but at a much reduced frequency and later onset than those co-deleted for Rb1. Pten deletion also led to a marked increase in adipocytes in the bone marrow. To better understand the function of Pten in bone development in vivo, we conditionally deleted Pten in OSX+ osteoprogenitor cells using OSX-Cre mice. μCT analysis revealed a significant thickening of the calvaria and an increase in trabeculae volume and number in the femur, consistent with increased bone formation in these mice. To determine if Pten and Rb1 deletion actively promotes adipogenic differentiation, we isolated calvarial cells from Ptenfl/fl and Ptenfl/fl; Rb1fl/fl mice, infected them with CRE or GFP expressing adenovirus, treated with differentiation media. We observed slightly increased adipogenic, and osteogenic differentiation in the ΔPten cells. Both phenotypes were greatly increased upon Rb1/Pten co-deletion. This was accompanied by an increase in expression of genes required for adipogenesis. These data indicate that Pten deletion in osteoblast precursors is sufficient to promote frequent adipogenic, but only rare osteogenic tumors. Rb1 hetero- or homo-zygous co-deletion greatly increases the incidence and the rapidity of onset of adipogenic tumors, again, with only rare osteosarcoma tumors. PMID:26317218

    The experience of same-sex-attracted people who have lost a partner is neglected in the existing literature on bereavement. Previous research on lesbian, gay, bisexual, transgender, intersex, queer and questioning (LGBTIQ) populations tends to focus on the loss of a partner to HIV-related causes, and there is scant research concerning non-HIV-related bereavement. The purpose of this article is to investigate the non-HIV-related bereavement experiences of same-sex partners and to address the potential complications of disenfranchised grief. Coping with the loss of a same-sex partner and the impact of bereavement on subsequent relationships are also discussed. Implications for counseling of bereaved same-sex-attracted individuals are drawn, and recommendations for future psychological research on the experience of bereavement are made.

    Published scientific protocols are advocated as a means of controlling bias in research reporting. Indeed, many journals require a study protocol with manuscript submission. However, publishing protocols of partnered research (PPR) can be challenging in light of the research model's dynamic nature, especially as no current reporting standards exist. Nevertheless, as these protocols become more prevalent, a priori documentation of methods in partnered research studies becomes increasingly important. Using as illustration a suite of studies aimed at improving coordination and communication in the primary care setting, we sought to identify challenges in publishing PPR relative to traditional designs, present alternative solutions to PPR publication, and propose an initial checklist of content to be included in protocols of partnered research. Challenges to publishing PPR include reporting details of research components intended to be co-created with operational partners, changes to sampling and entry strategy, and alignment of scientific and operational goals. Proposed solutions include emulating reporting standards of qualitative research, participatory action research, and adaptive trial designs, as well as embracing technological tools that facilitate publishing adaptive protocols, with version histories that are able to be updated as major protocol changes occur. Finally, we present a proposed checklist of reporting elements for partnered research protocols.

    1994-01-01

    Few investigations of sexual attitudes have restricted their focus to individuals' preferences for specific behaviors within a heterosexual relationship. None have examined gender differences in a broad and multidimensional array of such behavioral particulars. As part of an effort to develop a measure of preferred scripts in heterosexual couples, 258 men and women reported how much they agreed or disagreed with 74 statements of preference. A reduced and factor analyzed questionnaire included 38 items and was administered to a second sample (N = 228). Results offer qualified support that, compared to women, men are more erotophilic and show a stronger preference for incorporating erotic materials as well as drugs and alcohol into sexual relations with their partner. These results were more robust in the second sample, in which almost half of the subjects were tested in same-sex groups. Across both samples, women showed stronger preferences for activities reflecting romanticism. No gender differences were evident in sexual conventionality or in preference regarding the general use of contraceptives. However, results suggest that both sexes respond more favorably to a partner-focused or unspecified contraceptive method than to a self-focused method.

    OBJECTIVE Tethered cord syndrome is the clinical manifestation of an abnormal stretch on the spinal cord, presumably causing mechanical injury, a compromised blood supply, and altered spinal cord metabolism. Tethered cord release is the standard treatment for tethered cord syndrome. However, direct untethering of the spinal cord carries potential risks, such as new neurological deficits from spinal cord injury, a CSF leak from opening the dura, and retethering of the spinal cord from normal scar formation after surgery. To avoid these risks, the authors applied spinal column shortening to children and transitional adults with primary and secondary tethered cord syndrome and report treatment outcomes. The authors' aim with this study was to determine the safety and efficacy of spinal column shortening for tethered cord syndrome by analyzing their experience with this surgical technique. METHODS The authors retrospectively reviewed the demographic and procedural data of children and young adults who had undergone spinal column shortening for primary or secondary tethered cord syndrome. RESULTS Seven patients with tethered cord syndrome caused by myelomeningocele, lipomyelomeningocele, and transitional spinal lipoma were treated with spinal column shortening. One patient with less than 24 months of follow-up was excluded from further analysis. There were 3 males and 4 females; the average age at the time was surgery was 16 years (range 8-30 years). Clinical presentations for our patients included pain (in 5 patients), weakness (in 4 patients), and bowel/bladder dysfunction (in 4 patients). Spinal column osteotomy was most commonly performed at the L-1 level, with fusion between T-12 and L-2 using a pedicle screw-rod construct. Pedicle subtraction osteotomy was performed in 6 patients, and vertebral column resection was performed in 1 patient. The average follow-up period was 31 months (range 26-37 months). Computed tomography-based radiographic outcomes showed solid

    Partnering is an ideal field if someone is seeking to move from a scientific to a more business-oriented discipline. Partnering's goal is to identify and acquire external innovation. These discoveries are then included in a company's pipeline and help bring novel treatments to patients. Advanced scientific training is essential in the identification and evaluation of these external assets. Here I describe how partnering works in a pharmaceutical company and offer advice on how to make a successful transition from a PhD program to a business career. © 2017 Hofmann.

    Prior mate preference research has focused on the content of mate preferences. Yet in real life, people must select mates among potentials who vary along myriad dimensions. How do people incorporate information on many different mate preferences in order to choose which partner to pursue? Here, in Study 1, we compare seven candidate algorithms for integrating multiple mate preferences in a competitive agent-based model of human mate choice evolution. This model shows that a Euclidean algorithm is the most evolvable solution to the problem of selecting fitness-beneficial mates. Next, across three studies of actual couples (Study 2: n = 214; Study 3: n = 259; Study 4: n = 294) we apply the Euclidean algorithm toward predicting mate preference fulfillment overall and preference fulfillment as a function of mate value. Consistent with the hypothesis that mate preferences are integrated according to a Euclidean algorithm, we find that actual mates lie close in multidimensional preference space to the preferences of their partners. Moreover, this Euclidean preference fulfillment is greater for people who are higher in mate value, highlighting theoretically-predictable individual differences in who gets what they want. These new Euclidean tools have important implications for understanding real-world dynamics of mate selection.

    Pulmonary fibrosis greatly impacts patients and their partners. Unmet needs of patients are increasingly acknowledged; the needs of partners often remain unnoticed. Little is known about the best way to educate patients and partners. We investigated pulmonary fibrosis patients' and partners' perspectives and preferences in care, and the differences in these between the Netherlands and Germany. Additionally, we evaluated whether interactive interviewing could be a novel education method in this population. Patients and partners were interviewed during pulmonary fibrosis patient information meetings. In the Netherlands, voting boxes were used and results were projected directly. In Germany, questionnaires were used. In the Netherlands, 278 patients and partners participated; in Germany, 51. Many participants experienced anxiety. Almost all experienced misunderstanding, because people do not know what pulmonary fibrosis is. All expressed a need for information, psychological support and care for partners. Use of the interactive voting system was found to be pleasant (70%) and informative (94%). This study improves the knowledge of care needs of patients with pulmonary fibrosis and their partners. There were no major differences between the Netherlands and Germany. Interactive interviewing could be an attractive method to acquire insights into the needs and preferences of patients and partners, while providing them with information at the same time.

    Partner violence is a serious public health problem affecting mostly women. This qualitative study assessed the perceptions of rural Igbo women of Nigeria of intimate partner violence. Information was elicited using in-depth interviews and focus group discussion. Women of childbearing age were selected from the various women age grades in Ozubulu, Anambra State, Nigeria. Findings revealed that the women generally condone and are complacent with intimate partner violence, perceiving it as cultural and religious norms. The women felt that reprimands, beating and forced sex affecting their physical, mental and reproductive wellbeing are normal in marriage. They did not support reporting such cases to the police or divorcing the man, they would rather prefer reporting to family members. They felt that exiting the marriage would not gain the support of family members. They also expressed fear for the uncertainty in re-marrying, means of livelihood after re-marriage, social stigmatisation, and concern for their children. Socio-cultural norms and structures favour partner violence in Anambra State of Nigeria. There is a need for advocacy and concerted action that will involve the educational, health, civil and religious sectors of the society to evolve sustainable structures that will empower women and provide support to enable victims to react appropriately to violence.

  9. Partner choice, relationship satisfaction, and oral contraception: the congruency hypothesis.

    Hormonal fluctuation across the menstrual cycle explains temporal variation in women's judgment of the attractiveness of members of the opposite sex. Use of hormonal contraceptives could therefore influence both initial partner choice and, if contraceptive use subsequently changes, intrapair dynamics. Associations between hormonal contraceptive use and relationship satisfaction may thus be best understood by considering whether current use is congruent with use when relationships formed, rather than by considering current use alone. In the study reported here, we tested this congruency hypothesis in a survey of 365 couples. Controlling for potential confounds (including relationship duration, age, parenthood, and income), we found that congruency in current and previous hormonal contraceptive use, but not current use alone, predicted women's sexual satisfaction with their partners. Congruency was not associated with women's nonsexual satisfaction or with the satisfaction of their male partners. Our results provide empirical support for the congruency hypothesis and suggest that women's sexual satisfaction is influenced by changes in partner preference associated with change in hormonal contraceptive use.

  10. Effects of partner beauty on opposite-sex attractiveness judgments.

    Many studies show mate choice copying effects on mate preferences in non-human species in which individuals follow or copy the mate choices of same-sex conspecifics. Recent studies suggest that social learning also influences mate preferences in humans. Studies on heterosexual humans have focused on rating the attractiveness of potential mates (targets) presented alongside individuals of the opposite sex to the target (models). Here, we examined several different types of pairing to examine how specific social learning is to mate preferences. In Study 1, we replicated a previous effect whereby target faces of the opposite sex to the subject were rated as more attractive when paired with attractive than unattractive partner models of the same sex as the subject. Using the same paired stimuli, Study 2 demonstrated no effect of a paired model if subjects were asked to rate targets who were the same sex as themselves. In Study 3, we used pairs of the same sex, stating the pair were friends, and subjects rated targets of the opposite sex to themselves. Attractive models decreased targets' attractiveness, opposite to the effect in Study 1. Finally, Study 4 examined if attractive versus unattractive non-face stimuli might influence attraction. Unlike in Study 1, pairing with attractive stimuli either had no effect or decreased the attractiveness of paired target face images. These data suggest that social transmission of preferences via pairing with attractive/unattractive images is relatively specific to learning about mate preferences but does not influence attractiveness judgments more generally.

    A representative British sample of 257 adults completed a questionnaire in which they indicated their preference for eight dentists stratified by sex, age, and training location. These data were analysed in relation to participants' own sex and age, the latter stratified by a median split. A mixed analysis of variance indicated two main effects: a preference for younger (rather than older) dentists and dentists trained in Britain (rather than in Asia). There were also a significant two-way interaction between dentist age and training location: for the British-trained there was a preference for younger dentists, whereas for the Asian-trained there was a preference for older dentists. Limitations of the study design are discussed in conclusion.

    This qualitative study investigates the different methods for selecting sex partners by Korean homosexuals considering factors related to homosexual identity and sexual behavior. We take the approach of the grounded theory to examine the issue of sexual partnering of men who have sex with men (MSM). In-depth interviews of urban MSM and bisexual men were conducted. The snowball sampled through a MSM portal web site. Three key informants from the several areas were collected through a MSM portal website, and then, participants were gradually recruited with the snowball samplings in South Korea, 2011 (n=32). The results of coding the interviews based on the grounded theory approach identified three types of partnering: 1) MSM who do not prefer anal intercourse, but pursue safe sex in long-term relationships with fixed partners; 2) those who have fixed partners and perform anal sex, a category into which both MSM and bisexuals fall; and 3) those engaged in anal sex, but enjoy a concurrent sexual relationship without having fixed partners, which was common among bisexuals. The findings from this study elucidate several MSM and bisexual partnering types practice safe sex. This diversity in MSM partnering may increase the vulnerability of some MSM to HIV infection as safe-sex practices remain a matter of individual choice. Changes in Korean societal policies are necessary to enhance capacity building and encourage the practice of safe sex at the community level. PMID:27347275

    Guns figure prominently in the homicide of women by an intimate partner. Less is known, however, about their nonfatal use against an intimate partner. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched eight electronic databases and identified 10 original research articles that reported the prevalence of the nonfatal use of firearms against an intimate partner. Results indicate that (1) there is relatively little research on the subject of intimate partners' nonfatal gun use against women. (2) The number of U.S. women alive today who have had an intimate partner use a gun against them is substantial: About 4.5 million have had an intimate partner threaten them with a gun and nearly 1 million have been shot or shot at by an intimate partner. Whether nonfatal gun use is limited to the extreme form of abuse (battering) or whether it occurs in the context of situational violence remains to be seen. Regardless, when it comes to the likely psychological impact, it may be a distinction without a difference; because guns can be lethal quickly and with relatively little effort, displaying or threatening with a gun can create a context known as coercive control, which facilitates chronic and escalating abuse. Implications for policy, practice, and research are discussed, all of which include expanding an implicit focus on homicide to include an intimate partner's nonfatal use of a gun.

  16. Accounting for Intimate Partner Violence: A Biographical Analysis of Narrative Strategies Used by Men Experiencing IPV From Their Female Partners.

    2015-10-01

    Intimate partner violence (IPV) is a serious social issue which affects the medium- and long-term health outcomes of many individuals worldwide. The cost of IPV on the physical and psychological well-being of individuals, in addition to its wider economic costs in responding to abused persons, is significant. Presently, there is a lack of understanding about the nature of female-initiated IPV and how men account for their experiences of it. This study examined male victims' life stories of their IPV experiences from their intimate partners. Using the biographical narrative interpretive method, three cases were analyzed from a social constructionist perspective to examine what narrative strategies men used to account for their experiences of being abused by their female partners. Three dominant narrative strategies were used by respondents: the fatherhood narrative, the good husband narrative, and the abuse narrative. The abuse narrative had a unique narrative form, which reflected respondents' disassociation between their identities as men and also as abused persons. Dominant conflicting discourses of masculinity and intimate partner abuse disadvantaged men in identifying IPV and secondly in responding appropriately. This study found that men prefer to use dominant discursive identities as legitimate means from which to disclose IPV experiences. The findings from this study illustrate that broad questioning by professionals regarding fatherhood may be most helpful in promoting disclosures of IPV if this is suspected.

  17. If You’ve Got It, Flaunt It: Humans Flaunt Attractive Partners to Enhance Their Status and Desirability

    2013-01-01

    Mating decisions are influenced by conspecifics’ mate choices in many species including humans. Recent research has shown that women are more attracted to men with attractive putative partners than those with less attractive partners. We integrate these findings with traditional accounts of social signaling and test five hypotheses derived from it. In our study, 64 men and 75 women were paired with attractive and unattractive opposite-sex putative partners and asked whether they would prefer to give surveys to peers or to older adults. Consistent with predictions, both men and women wanted to show off (flaunt) attractive partners by administering surveys to peers and both men and women wanted to hide (conceal) unattractive partners from peers by administering surveys to older adults. These decisions were mediated by how participants expected others to evaluate their status and desirability when they administered the surveys, consistent with partners serving a social signaling function in humans.

  18. Preference for newspaper size.

    2014-05-01

    The past few years has seen a change in the size of newspapers, with publishers moving to a smaller size format. Five 'standard' newspaper sizes are used in different countries: Broadsheet, Rhensch, Tabloid, Tall Tabloid and Berliner. These papers vary in both width and height of pages and hence there are implications for human reading comfort, which may be dependent on reading location such as on a lounge chair or on a train. Experiments were carried out to determine preferences for the different sizes and to relate these preferences to the geometric characteristics of the newspapers. For both comfortable and cramped/uncomfortable reading conditions, the rank order of preference for paper types was, from least to most-preferred, Broadsheet, Rhensch, Berliner, Tall Tabloid and Tabloid. Preferences were much stronger when determined in cramped/uncomfortable reading conditions, where most comparisons were significantly different. There was good correlation between participant ratings on several scales and preference, where most factors were related to comfort of holding and controlling the paper.

    The supersymmetric partners of periodic potential are studied. It is seen that band edge eigenfunctions taken as transformation functions do not change the spectrum. However, solutions for factorization energies in forbidden bands produce final potentials which in addition can have bound states, giving place to localized periodicity defects.

    With support from the UN Population Fund, the Rockefeller Foundation, and the World Bank, Bangladesh, Colombia, Egypt, Indonesia, Kenya, Mexico, Morocco, Thailand, Tunisia, and Zimbabwe launched the Partners in Population and Development Program at the 1994 International Conference on Population and Development. The goal was to create a more effective mechanism through which developing countries can share their experiences in family planning and reproductive health. An interim secretariat was established at the Rockefeller Foundation in New York City, paving the way for a small secretariat in Dhaka, Bangladesh. The Partners' governing board, comprised of the highest-ranking officials responsible for reproductive health in each of the 10 countries, held a meeting in Mexico City attended by representatives of donor organizations and nongovernmental organizations, and by international experts in reproductive health research and policy. During associated field visits, there was an opportunity to see how Mexico caters to the reproductive health needs of its urban and rural populations. Mexico has many programs which other Partners could adapt for their own needs. Other Partner countries are equally willing to share their successes.

  9. Coevolution of Cooperation and Partner Rewiring Range in Spatial Social Networks

    Khoo, Tommy; Fu, Feng; Pauls, Scott

    2016-11-01

    In recent years, there has been growing interest in the study of coevolutionary games on networks. Despite much progress, little attention has been paid to spatially embedded networks, where the underlying geographic distance, rather than the graph distance, is an important and relevant aspect of the partner rewiring process. It thus remains largely unclear how individual partner rewiring range preference, local vs. global, emerges and affects cooperation. Here we explicitly address this issue using a coevolutionary model of cooperation and partner rewiring range preference in spatially embedded social networks. In contrast to local rewiring, global rewiring has no distance restriction but incurs a one-time cost upon establishing any long range link. We find that under a wide range of model parameters, global partner switching preference can coevolve with cooperation. Moreover, the resulting partner network is highly degree-heterogeneous with small average shortest path length while maintaining high clustering, thereby possessing small-world properties. We also discover an optimum availability of reputation information for the emergence of global cooperators, who form distant partnerships at a cost to themselves. From the coevolutionary perspective, our work may help explain the ubiquity of small-world topologies arising alongside cooperation in the real world.

    Cooperation is essential for human society, and children engage in cooperation from early on. It is unclear, however, how children select their partners for cooperation. We know that children choose selectively whom to learn from (e.g. preferring reliable over unreliable models) on a rational basis. The present study investigated whether children (and adults) also choose their cooperative partners selectively and what model characteristics they regard as important for cooperative partners and for informants about novel words. Three- and four-year-old children (N = 64) and adults (N = 14) saw contrasting pairs of models differing either in physical strength or in accuracy (in labeling known objects). Participants then performed different tasks (cooperative problem solving and word learning) requiring the choice of a partner or informant. Both children and adults chose their cooperative partners selectively. Moreover they showed the same pattern of selective model choice, regarding a wide range of model characteristics as important for cooperation (preferring both the strong and the accurate model for a strength-requiring cooperation tasks), but only prior knowledge as important for word learning (preferring the knowledgeable but not the strong model for word learning tasks). Young children’s selective model choice thus reveals an early rational competence: They infer characteristics from past behavior and flexibly consider what characteristics are relevant for certain tasks.

    Moore, Fhionna; Cassidy, Clare; Perrett, David I

    2010-12-03

    We tested the hypothesis that magnitudes of sex differences in human mate preferences would be inversely related to control of resources. Specifically, we predicted that the ideal partner age, maximum and minimum partner ages tolerated and preferences for "physical attractiveness" over "good financial prospects" of female participants would approach parity with that of men with increasing control of resources. In a sample of 3770 participants recruited via an online survey, the magnitudes of sex differences in age preferences increased with resource control whereas the sex difference in preferences for "physical attractiveness" over "good financial prospects" disappeared when resource control was high. Results are inconsistent, and are discussed in the context of adaptive tradeoff and biosocial models of sex differences in human mate preferences.

    Numerous studies point to partners' congruence in various domains and note an increase in their compatibility over time. However, none have explored a shift in chemosensory perception related to relationship duration. Here, we examined the relationship between the time heterosexual couples have spent together and the degree to which they share their gustatory and olfactory preferences. Additionally, we investigated whether these preferences are associated with relationship satisfaction. One-hundred couples aged from 18 to 68 years being together for a period between 3 and 540 months rated the pleasantness of a wide variety of olfactory and gustatory stimuli. We showed that both taste and smell preferences are more similar the longer couples have been in a relationship. We also observed a very interesting trend in terms of smell preferences, with relationship satisfaction being negatively related to congruence in smell preferences between partners. We discuss these results from the perspective of evolutionary psychology. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Public-private partnerships are fast becoming a preferred way to develop innovative remediation technologies. Many companies are taking part in such programs, which seek to harness both private-sector and public resources to spur development of innovative remediation technologies. In recent years, Clean Sites, a non-profit organization that seeks to improve the process of cleaning hazardous waste sites, has worked under a cooperative agreement with EPA`s Technology Innovation Office to develop these partnerships. One key aim is to gather hard data on performance and costs for full-scale implementation of innovative remediation technologies - many of which have been bench and pilot tested but lack a track record of successful field applications. Partnering with the federal government also increases opportunities for funding a full-scale demonstration. DOD, DOE, and EPA each invest significant resources in the demonstrations. In one case - the McClellan Air Force Base Public-Private Partnership - on-site activities are funded almost exclusively by the US Air Force and EPA.

  15. The Relationship between Partners’ Family-Size Preferences in Southern Malawi

    2015-01-01

    Studies of the relative influence of partners’ fertility preferences on behaviors tend to treat preferences as fixed, largely independent traits despite existing theoretical arguments and empirical evidence suggesting that they are moving targets that may be jointly developed within relationships. In this study, we use couple-level panel data from married and unmarried young adults in southern Malawi to examine the relationship between partners’ family-size preferences. We find evidence of assortative mating: young Malawians are more likely to partner with individuals who have similar family-size goals. Additionally, although partners’ family-size preferences do not perfectly converge, changes among men’s and women’s preferences are significantly more likely to be “toward” than “away from” those of their partner. Our findings point to a need for studies regarding the relative influence of partners on reproductive outcomes to consider the interdependence of partners’ preferences and the varied ways in which partners can influence shared reproductive behaviors.

    2017-01-01

    Motivations of low-income substance using heterosexual Black women in New York City for having multiple sexual partners are explored in this paper. Analysis of in-depth interviews with 50 study participants demonstrates that their relationships consisted of those who had: (1) a main sex partner and a secondary sex partner; or (2) two or more “casual” partners. Individual-level motivations for extra relational sex fell into four dominant themes: sexual pleasure, partner infidelity, sex exchange and past main partners. Using a Black feminist framework, we describe how participants displayed considerable autonomy by actively forming and withdrawing from sexual relationships with men. However, women described low rates of condom use with main partners and inconsistent use of condoms with more casual sexual partners. This contradiction becomes an important area for sexual health interventions. Women who had sexual relations with only one current mate in the past two years were recruited as a monogamous comparison group. PMID:28730162

    In a study of patients' views of the type of information they would like to receive from the doctor 265 patients from four general practices were given a list of five areas of information — diagnosis, prognosis, treatment, aetiology and social effects of their illness — and asked to rank these in order of importance for that visit. In general, information on diagnosis and prognosis was the most highly valued, while the ways the illness would affect daily activities was the least preferred. Although information on treatment was rarely selected as the first preference it was often the second or third preference. Conversely, diagnosis was the first choice of the largest proportion of patients and the least valued information for 26%. PMID:3440990

  1. Dilemmas in intimate partner violence.

    PubMed

    Cook, Rebecca J; Dickens, Bernard M

    2009-07-01

    Intimate partner violence (IPV), usually men's violence against women, appears universal. It may be associated with pregnancy, but this may be because pregnant women receive more medical attention. Violence may cause bruises, abrasions, and cuts, but its extremes include hospitalization, death, and suicide. IPV is often disclosed when women are asked why they feel in poor health or depressed. A legal dilemma arises when healthcare providers consider that intervention such as law-enforcement is appropriate, but patients refuse approval. Patients may fatalistically accept violence, or fear loss of support for their children and themselves if their partners are held in custody. Legal reforms, such as punishing spousal rape, may provide some protection of women's autonomy. Ethical dilemmas concern intervention without patients' approval, and whether treating violent injuries without taking preventive action breaches the principle to Do No Harm. Professional advocacy and social action have been urged to expose and reduce IPV.

    This study compared actors', partners', and observers' perceptions of the amount of sarcasm used by participants (n = 80) in videotaped conversations. Significant differences were found among perceptions of actors, partners, and observers. Of the three perspectives, actors perceived themselves as using the greatest amount of sarcasm, followed by partners' perceptions of actors. Observers perceived actors as using the least amount of sarcasm. Correlations conducted to assess whether partners and observers recognized actors' individual attempts at sarcasm during the conversations were generally low.

  3. Metal Preferences and Metallation*

    Foster, Andrew W.; Osman, Deenah; Robinson, Nigel J.

    2014-01-01

    The metal binding preferences of most metalloproteins do not match their metal requirements. Thus, metallation of an estimated 30% of metalloenzymes is aided by metal delivery systems, with ∼25% acquiring preassembled metal cofactors. The remaining ∼70% are presumed to compete for metals from buffered metal pools. Metallation is further aided by maintaining the relative concentrations of these pools as an inverse function of the stabilities of the respective metal complexes. For example, magnesium enzymes always prefer to bind zinc, and these metals dominate the metalloenzymes without metal delivery systems. Therefore, the buffered concentration of zinc is held at least a million-fold below magnesium inside most cells. PMID:25160626

  4. Desistance From Intimate Partner Violence

    2015-01-01

    Intimate partner violence (IPV) is an international issue that social and criminal justice workers will encounter regularly. It has been identified that men can, and do stop using, or desist from, IPV although it is unclear how this process of change develops. This article introduces a conceptual model to outline how the process of desistance evolves and what it encompasses. Using thematic analysis of interview data from partner-violent men, survivors, and treatment facilitators, the resulting model demonstrates that the process of change is a dynamic one where men’s use of, and cessation from, violence needs to be understood within the context of each individual’s life. Three global themes were developed: (a) lifestyle behaviors (violent): what is happening in the men’s lives when they use violence; (b) catalysts for change: the triggers and transitions required to initiate the process of change; and (c) lifestyle behaviors (non-violent): what is different in the men’s lives when they have desisted from IPV. The purpose of this model is to offer a framework for service providers to assist them to manage the process of change in partner-violent men. PMID:25315483

  10. Height preferences in humans may not be universal: evidence from the Datoga people of Tanzania.

    PubMed

    Sorokowski, P; Butovskaya, M L

    2012-09-01

    Many studies in Western societies have shown that women prefer relatively taller men as potential partners, whereas men prefer women who are slightly shorter than themselves. Here, we discuss possible limitations of previous results within the context of the stimuli used (i.e., differences in the perceived body size of female silhouettes). Our results show that, at least in a Polish sample (N=231), modified stimuli did not essentially change the observed male-taller preferences. In contrast, we report height preferences in a traditional ethnic group, the Datoga people from Tanzania (N=107), in which men and women preferred extreme sexual dimorphism in stature (SDS) sets (i.e., men and women chose women much taller or much shorter than themselves). Thus, our data do not accord with the suggestion of a universal preference for taller men, but rather suggests that height preferences may be influenced by cultural, environmental, and ecological conditions.

  11. Pair bonding and lateral neck-resting preferences in captive Caribbean flamingos (Phoenicopterus ruber).

    When flamingos rest, they typically lay their head on their back and curve their neck to either the right or left of their body, with both individual and population-level lateral preferences for rightward neck resting when preferences are tracked over time (Anderson, Williams, & O'Brien, 2009). The present study attempted to replicate these previous neck-resting preferences, to examine how they changed over time, and to examine the possibility of a relationship between lateral neck-resting preference and pair bonding in captive Caribbean flamingos (Phoenicopterus ruber) housed at the Philadelphia Zoo (Philadelphia, PA, USA). Results successfully replicated the individual- and population-level lateral preferences for rightward neck resting, and demonstrated that these preferences were stable over time. Moreover, individual flamingos that demonstrated stronger pair bond strengths tended to differ less from their partners in terms of neck-resting preference than did those birds displaying weaker pair bond strengths, suggesting a relationship between laterality and social cohesion.

    A systematic investigation of the role of prenatal partner support in perinatal maternal depression was conducted. Separate facets of partner support were examined (i.e., received support and support adequacy) and a multidimensional model of support was applied to investigate the effects of distinct types of support (i.e., informational, physical comfort, emotional/esteem, and tangible support). Both main and stress-buffering models of partner support were tested in the context of prenatal maternal stress resulting from exposure to a natural disaster. Questionnaire data were analyzed from 145 partnered women using growth curve analytic techniques. Results indicate that received support interacts with maternal flood stress during pregnancy to weaken the association between stress and trajectories of maternal depression from pregnancy to 30 months postpartum. Support adequacy did not interact with stress, but was associated with levels of depressive symptoms controlling for maternal stress and received support. Results demonstrate the distinct roles of various facets and types of support for a more refined explanatory model of prenatal partner support and perinatal maternal depression. Results inform both main effect and stress buffering models of partner support as they apply to the etiology of perinatal maternal depression, and highlight the importance of promoting partner support during pregnancy that matches support preferences.

  17. Hormonal contraceptives suppress oxytocin-induced brain reward responses to the partner's face.

    PubMed

    2016-05-01

    The hypothalamic peptide oxytocin (OXT) has been identified as a key modulator of pair-bonding in men, but its effects in women are still elusive. Moreover, there is substantial evidence that hormonal contraception (HC) influences partner preferences and sexual satisfaction, which constitute core domains of OXT function. We thus hypothesized that OXT effects on partner-related behavioral and neural responses could be significantly altered in women using HC. In this functional magnetic resonance imaging study involving 40 pair-bonded women, 21 of whom were using HC, we investigated whether a 24-IU nasal dose of OXT would modulate brain reward responses evoked by the romantic partner's face relative to the faces of familiar and unfamiliar people. Treatment with OXT increased the perceived attractiveness of the partner relative to other men, which was paralleled by elevated responses in reward-associated regions, including the nucleus accumbens. These effects of OXT were absent in women using HC. Our results confirm and extend previous findings in men that OXT interacts with the brain reward system to reinforce partner value representations, indicating a common OXT-dependent mechanism underlying partner attraction in both sexes. This mechanism may be disturbed in women using HC, suggesting that gonadal steroids could alter partner-specific OXT effects.

  18. How online counselling can support partners of individuals with problem alcohol or other drug use.

    2017-07-01

    Problematic alcohol and other drug (AOD) use impacts partners heavily, with an increased risk of experiencing domestic violence, financial stressors, health problems and relationship challenges. However, partners often do not seek help or support due to a range of barriers (e.g., shame, stigma, practical constraints). Online counselling may facilitate help-seeking by overcoming many of these barriers, however research is needed to explore what motivates partners to contact online counselling services, their experiences and needs, and how partners can be best supported online. One hundred transcripts of partners of individuals with problem AOD use were sampled from a 24-hour national AOD synchronous online chat counselling service. Descriptive content analysis was used to investigate themes related to help-seeking. Three broad themes, with seven sub-themes, were identified: (i) the reason for accessing online counselling (seeking advice, wanting to talk), (ii) discussing help-seeking and coping processes (past/present help-seeking or coping strategies, barriers and facilitators to seeking help and change), and (iii) planning for future assistance (future planning, treatment preferences). Partners wanted to talk about their concerns with a non-judgemental professional. However, the majority of help-seekers wanted advice and assistance in problem-solving, coping and the process of seeking further help. Future studies need to examine the impact of online help-seeking by partners. Copyright © 2017 Elsevier Inc. All rights reserved.

    Research suggests that paternal re-partnering and new-partner fertility are associated with decreased nonresident father investments in children. Few studies, however, have examined the influence of maternal re-partnering and new-partner births on nonresident father investments. We use data from the National Longitudinal Survey of Youth to examine associations of maternal re-partnering (through cohabitation or marriage with a new partner) and new-partner births with nonresident father visitation and child support payments. Results suggest that maternal re-partnering is associated with a decrease in both yearly father-child contact and child support received by the mother. New-partner fertility for mothers who are co-residing with a partner is associated with an additional decrease in monthly father-child contact, but does not have an additional influence on yearly father-child contact or child support receipt.

This can help maintain underground cooperation, although it is likely that different plant species vary in the spatial precision with which they can select partners. Partner selection in the mycorrhizal symbiosis is presumably context-dependent and can be mediated by factors like (relative) resource abundance and resource fluctuations, competition among mycorrhizas, arrival order and cultivation history. Such factors complicate our current understanding of the importance of partner selection and its effectiveness in stimulating mutualistic cooperation.

    Background Posterior interosseous nerve (PIN) palsy may present with various symptoms, and may resemble cervical spondylosis. Case report We report about a 59-year-old patient with cervical spondylosis which delayed the diagnosis of posterior interosseous nerve (PIN) palsy due to an intermuscular lipoma. Initial right hand paraesthesias and clumsiness, together with MR findings of right C5–C6 and C6–C7 foraminal stenosis, misled the diagnostic investigation. The progressive loss of extension of all right hand fingers brought to detect a painless mass compressing the PIN. Electrophysiological studies confirmed a right radial motor neuropathy at the level of the forearm. Results Surgical tumor removal and nerve decompression resulted in a gradual motor deficits recovery. Conclusions A thorough clinical examination is paramount, and electrophysiology may differentiate between cervical and peripheral nerve lesions. Ultrasonography and MR offer an effective evaluation of lipomas, which represent a rare cause of PIN palsy. Surgical decompression and lipoma removal generally determine excellent prognoses, with very few recurrences. PMID:27142825

  3. Conducting Clinically Based Intimate Partner Violence Research: Safety Protocol Recommendations.

    Anderson, Jocelyn C; Glass, Nancy E; Campbell, Jacquelyn C

    Maintaining safety is of utmost importance during research involving participants who have experienced intimate partner violence (IPV). Limited guidance on safety protocols to protect participants is available, particularly information related to technology-based approaches to informed consent, data collection, and contacting participants during the course of a study. The purpose of the article is to provide details on the safety protocol developed and utilized with women receiving care at an urban HIV clinic and who were taking part in an observational study of IPV, mental health symptoms, and substance abuse and their relationship to HIV treatment adherence. The protocol presents the technological strategies to promote safety and allow autonomy in participant decision-making throughout the research process, including Voice over Internet Protocol telephone numbers, and tablet-based eligibility screening and data collection. Protocols for management of participants at risk for suicide and/or intimate partner homicide that included automated high-risk messaging to participants and research staff and facilitated disclosure of risk to clinical staff based on participant preferences are discussed. Use of technology and partnership with clinic staff helped to provide an environment where research regarding IPV could be conducted without undue burden or risk to participants. Utilizing tablet-based survey administration provided multiple practical and safety benefits for participants. Most women who screened into high-risk categories for suicide or intimate partner homicide did not choose to have their results shared with their healthcare providers, indicating the importance of allowing participants control over information sharing whenever possible.

  4. Science Partners for Teachers: Graduate Student-Teacher Partnerships

    Science Partners for Teachers is a group of scientists (mostly graduate students) in the physical and biological sciences at the University of Chicago which establishes one-on-one partnerships with Chicago-area K-12 school teachers. The goal is to have both partners benefit from the interaction. As scientists, we want to learn more about how to teach, how to develop lesson plans, and improve our ability to disseminate scientific knowledge (with an eye towards increasing our marketability for our future job searches). In exchange, we offer to be a resource for teachers looking to update their science curricula and to help incorporate and increase the use of computers, and the internet into the classroom. But most of all, we want to develop a relationship in which the scientist gains an inside look at teaching while the teacher gains an inside look at science and the way science is done. This model for scientist-teacher interaction is unique among the ones we have encountered as it involves a one-on-one partnering between adults (no K-12 students involved) and is specficially tailored to mesh well with an over-committed graduate student's schedule. This group was founded and continues to be run by several astrophysics graduate students who are looking for creative ways to help themselves and other grad students prepare for alternative careers related to education, preferably involving both research and outreach.

    Post-coma individuals emerging from a minimally conscious state with multiple disabilities may enjoy contact with relevant partners (e.g., family members and friends), but may not have easy access to them. These two single-case studies assessed whether those individuals could make contact with partners through computer-aided telephone technology and enjoy such contact. The technology involved a computer system with special software, a global system for mobile communication modem (GSM), and microswitch devices. In Study I, the computer system presented a 23-year-old man the names of the partners that he could contact, one at a time, automatically. Together with each partner's name, the system also presented the voice of the partner asking the man whether he wanted to call him or her. The man could (a) place a call to that partner by activating a camera-based microswitch through mouth movements or (b) bypass that partner and wait for the next one to be presented. In Study II, the system presented a 36-year-old man the partners' names only after he had activated his wobble microswitch with a hand movement. The man could place a call or bypass a partner as in Study I. The results showed that both men (a) were able to contact relevant partners through the technology, (b) seemed to enjoy their telephone-mediated communication contacts with the partners, and (c) showed preferences among the partners. Implications of the findings are discussed.

    Primate affiliative relationships are differentiated, individual-specific and often reciprocal. However, the required cognitive abilities are still under debate. Recently, we introduced the EMO-model, in which two emotional dimensions regulate social behaviour: anxiety-FEAR and satisfaction-LIKE. Emotional bookkeeping is modelled by providing each individual with partner-specific LIKE attitudes in which the emotional experiences of earlier affiliations with others are accumulated. Individuals also possess fixed partner-specific FEAR attitudes, reflecting the stable dominance hierarchy. In this paper, we focus on one key parameter of the model, namely the degree of partner selectivity, i.e. the extent to which individuals rely on their LIKE attitudes when choosing affiliation partners. Studying the effect of partner selectivity on the emergent affiliative relationships, we found that at high selectivity, individuals restricted their affiliative behaviours more to similar-ranking individuals and that reciprocity of affiliation was enhanced. We compared the emotional bookkeeping model with a control model, in which individuals had fixed LIKE attitudes simply based on the (fixed) rank-distance, instead of dynamic LIKE attitudes based on earlier events. Results from the control model were very similar to the emotional bookkeeping model: high selectivity resulted in preference of similar-ranking partners and enhanced reciprocity. However, only in the emotional bookkeeping model did high selectivity result in the emergence of reciprocal affiliative relationships that were highly partner-specific. Moreover, in the emotional bookkeeping model, LIKE attitude predicted affiliative behaviour better than rank-distance, especially at high selectivity. Our model suggests that emotional bookkeeping is a likely candidate mechanism to underlie partner-specific reciprocal affiliation.

    Pro-sociality, i.e., the preference for outcomes that produce benefits for other individuals, is ubiquitous in humans. Recently, cross-species comparisons of social behavior have offered important new insights into the evolution of pro-sociality. Here, we present a rodent analog of the Pro-social Choice Task that controls strategic components, de-confounds other-regarding choice motives from the animals' natural tendencies to maximize own food access and directly tests the effect of social context on choice allocation. We trained pairs of rats—an actor and a partner rat—in a double T-maze task where actors decided between two alternatives only differing in the reward delivered to the partner. The “own reward” choice yielded a reward only accessible to the actor whereas the “both reward” choice produced an additional reward for a partner (partner condition) or an inanimate toy (toy Condition), located in an adjacent compartment. We found that actors chose “both reward” at levels above chance and more often in the partner than in the toy condition. Moreover, we show that this choice pattern adapts to the current social context and that the observed behavior is stable over time. PMID:25642162

    Distinctions are commonly made regarding preferences for insertive or receptive anal intercourse within gay male communities. Three sexual self-labels are typically specified: "top," meaning a man who prefers the insertive role, "bottom," meaning a man who prefers the receptive role, and "versatile," meaning a man willing to perform either role. In this study, we examined the association between intercourse position preference and preference for male facial masculinity among 447 gay men across multiple cities in China. Each participant was shown 10 pairs of male faces sequentially, with each pair consisting of a masculinized and feminized version of the same base face. Tops preferred the feminized male face over the masculinized face, bottoms preferred the masculinized male face over the feminized face, and versatiles did not have a preference. Tops preferred more feminized male faces than did bottoms and versatiles. Preferences for male facial masculinity were also associated with sociosexual orientation and the nature of the associations differed by sex role preferences. Among tops, men who were less restricted preferred more feminine male faces compared to men who were more restricted. Among bottoms, men who were less restricted preferred more masculine male faces compared to men who were more restricted. Among versatiles, there was no association between sociosexual orientation and preferences for male facial masculinity. These findings provide new evidence that less sociosexually restricted men have stronger preferences for sexual dimorphism in the sexual partners they prefer than do more restricted men.

    U.S. women have worse HAART and HIV health outcomes compared to U.S. men. The study examined main partner factors associated with women's HAART adherence. The community sample comprised 85% African Americans; 63% had a main partner and 32% relied on their partner for emotional support. Adherence was highest (92%) among those without a main partner, and lowest (57%) among those with an HIV seropositive main partner. In adjusted analysis, adherence was 75% less likely among women with an HIV seropositive main partner, and 78% less likely among those relying on their partner for emotional support. Furthermore, HIV seropositive versus other serostatus main partners were most likely to provide medication taking assistance and to be preferred in helping participants deal with HIV, yet were no more likely to be nominated as the most helpful to them. Findings reveal women's perceived unmet support needs from HIV seropositive main partners in this population, and the need for interventions to promote their HAART adherence. Seroconcordant couples-focused intervention that enhances mutual support of HAART adherence may be an effective approach to improving women's HAART adherence and reducing US gender disparities in HIV health outcomes.

    2012-12-01

    The present study investigated the role of 24 character strengths in 87 adolescent romantic relationships focusing on their role in partner selection and their role in mates' life satisfaction. Measures included the Values in Action Inventory of Strengths for Youth, the Students' Life Satisfaction Scale, and an Ideal Partner Profiler for the composition of an ideal partner. Honesty, humor, and love were the most preferred character strengths in an ideal partner. Hope, religiousness, honesty, and fairness showed the most substantial assortment coefficients. Hierarchical regression analyses revealed targets' character strengths as explaining variance in targets' life satisfaction. Furthermore, to a lesser degree, specific character strengths of partners and couples' similarity in certain character strengths explained variance in targets' life satisfaction beyond targets' character strengths. This first research on this topic showed that character strengths play a significant role in adolescent romantic relationships.

    The study examined the coaching preferences of 80 male and 80 female athletes, as measured by the Leadership Scale for Sports (Chelladurai and Saleh, 1978, 1980). In addition, it attempted to assess the applicability to sport of the Life-cycle and Path-goal theories of leadership. Comparisons between groups were made on the basis of sex, age, and type of sport. A MANOVA indicated that athletes in independent sports preferred more democratic behaviour (p less than .001) and less autocratic behaviour (p = .028) than athletes in interdependent sports. No differences in coaching preferences were found which could be attributed to the age or sex of the athlete, or the variability of the sports task. These results partially supported the Path-goal theory, but did not support the Life-cycle theory. Athletes of all groups tended to favour coaches who displayed training behaviour and rewarding behaviour "often", democratic behaviour and social support behaviour "occasionally", and autocratic behaviour "seldom". This consistency may be a useful finding for those organizations and institutions interested in preparing coaches.

  13. Semiconductor foundry, lithography, and partners

    The semiconductor foundry took off in 1990 with an annual capacity of less than 0.1M 8-inch-equivalent wafers at the 2-mm node. In 2000, the annual capacity rose to more than 10M. Initially, the technology practiced at foundries was 1 to 2 generations behind that at integrated device manufacturers (IDMs). Presently, the progress in 0.13-mm manufacturing goes hand-in-hand with any of the IDMs. There is a two-order of magnitude rise in output and the progress of technology development outpaces IDMs. What are the reasons of the success? Is it possible to sustain the pace? This paper shows the quick rise of foundries in capacity, sales, and market share. It discusses the their uniqueness which gives rise to advantages in conjunction with challenges. It also shows the role foundries take with their customer partners and supplier partners, their mutual dependencies, as well as expectations. What role then does lithography play in the foundries? What are the lithographic challenges to sustain the pace of technology? The experience of technology development and transfer, at one of the major foundries, is used to illustrate the difficulties and progresses made. Looking into the future, as semiconductor manufacturing will become even more expensive and capital investment more prohibitive, we will make an attempt to suggest possible solutions.

    Vaccine development, supported by infusions of public and private venture capital, is re-entering a golden age as one of the fastest growing sectors in the life-sciences industry. Demand is driven by great unmet need in underdeveloped countries, increased resistance to current treatments, bioterrorism, and for prevention indications in travelers, pediatric, and adult diseases. Production systems are becoming less reliant on processes such as egg-based manufacturing, while new processes can help to optimize vaccines. Expeditious development hinges on efficient study conduct, which is greatly enhanced through research partnerships with specialized contract research organizations (CROs) that are licensed and knowledgeable in the intricacies of immunology and with the technologic and scientific foundation to support changing timelines and strategies inherent to vaccine development. The CRO often brings a more objective assessment for probability of success and may offer alternative development pathways. Vaccine developers are afforded more flexibility and are free to focus on innovation and internal core competencies. Functions readily outsourced to a competent partner include animal model development, safety and efficacy studies, immunotoxicity and immunogenicity, dose response studies, and stability and potency testing. These functions capitalize on the CRO partner's regulatory and scientific talent and expertise, and reduce infrastructure expenses for the vaccine developer. Successful partnerships result in development efficiencies, elimination or reduced redundancies, and improved time to market. Keys to success include honest communications, transparency, and flexibility.

  15. AIP and its interacting partners.

    2011-08-01

    Germline mutations in the aryl hydrocarbon receptor-interacting protein gene (AIP) predispose to young-onset pituitary tumours, most often to GH- or prolactin-secreting adenomas, and most of these patients belong to familial isolated pituitary adenoma families. The molecular pathway initiated by the loss-of-function AIP mutations leading to pituitary tumour formation is unknown. AIP, a co-chaperone of heat-shock protein 90 and various nuclear receptors, belongs to the family of tetratricopeptide repeat (TPR)-containing proteins. It has three antiparallel α-helix motifs (TPR domains) that mediate the interaction of AIP with most of its partners. In this review, we summarise the known interactions of AIP described so far. The identification of AIP partners and the understanding of how AIP interacts with these proteins might help to explain the specific phenotype of the families with heterozygous AIP mutations, to gain deeper insight into the pathological process of pituitary tumour formation and to identify novel drug targets.

    This research examined maternal and partner warmth as moderators of the relation between men's intimate partner aggression and children's externalizing problems. Participants were 157 mothers and their children (ages 7-9 years). Results indicate that maternal and partner warmth each moderated the relation between men's intimate partner aggression and children's externalizing problems. Partner-to-mother aggression was positively associated with child reports of externalizing problems at lower, but not higher, levels of maternal warmth. Similarly, partner-to-mother aggression was positively associated with mother reports of girls', but not boys', externalizing problems at lower, but not higher, levels of maternal warmth. On the other hand, the moderating effect of partner warmth was in the opposite direction and was found only with child-reported externalizing problems. Increased levels of partner-to-mother aggression related positively to child-reported externalizing problems when partners were higher, but not lower, in warmth.

  17. To Punish or to Leave: Distinct Cognitive Processes Underlie Partner Control and Partner Choice Behaviors

    2015-01-01

    When a cooperative partner defects, at least two types of response are available: Punishment, aimed at modifying behavior, and ostracism, aimed at avoiding further social interaction with the partner. These options, termed partner control and partner choice, have been distinguished at behavioral and evolutionary levels. However, little work has compared their cognitive bases. Do these disparate behaviors depend on common processes of moral evaluation? Specifically, we assess whether they show identical patterns of dependence on two key dimensions of moral evaluation: A person’s intentions, and the outcomes that they cause. We address this issue in a “trembling hand” economic game. In this game, an allocator divides a monetary stake between themselves and a responder based on a stochastic mechanism. This allows for dissociations between the allocator’s intent and the actual outcome. Responders were either given the opportunity to punish or reward the allocator (partner control) or to switch to a different partner for a subsequent round of play (partner choice). Our results suggest that partner control and partner choice behaviors are supported by distinct underlying cognitive processes: Partner control exhibits greater sensitivity to the outcomes a partner causes, while partner choice is influenced almost exclusively by a partner’s intentions. This cognitive dissociation can be understood in light of the unique adaptive functions of partner control and partner choice. PMID:25915550

    2014-01-01

    This study assessed the extent to which environmental (Census block-group alcohol outlet density, neighborhood demographic characteristics) and partner risk factors (e.g., hazardous drinking, psychosocial characteristics) contribute to the likelihood of intimate partner violence among 1,753 couples residing in 50 medium-to-large California cities. Multilevel logistic regression models were used to analyze the role of alcohol outlets (off-premise outlets, bars/pubs and restaurants), neighborhood demographic characteristics, and partner risk factors in relation to male-to-female partner violence (MFPV) and female-to-male partner violence (FMPV) risk. Approximately 12% of couples reported past-year partner violence. Results showed that none of the environmental measures were related to MFPV or FMPV. Male partner's impulsivity and each partner's adverse childhood experiences were associated with MFPV risk. Risk factors for FMPV were male partner's impulsivity and frequency of intoxication and female partner's adverse childhood experiences. Individual/couple characteristics appear to be the most salient IPV risk factors. The male partner's heavy drinking may lead to negative partner/spousal interactions that result in FMPV. The male partner's impulsivity, and each partner's adverse childhood experiences, may potentiate couple conflict and result in aggression. Interventions that target prevention of family dysfunction during childhood may help reduce interpersonal violence in adulthood. PMID:24812578

    The relationship between support from members of a mother's social network and breastfeeding continuation is receiving increased attention. The objectives of this study were to describe the infant feeding preferences of Chinese mothers' immediate social network and to examine the association between these preferences and early breastfeeding cessation. In total, 1172 mother-infant pairs were recruited from 4 public hospitals in Hong Kong and followed prospectively for 12 months or until breastfeeding stopped. Over 40% of participants' partners preferred breastfeeding and half had no infant feeding preference. Only about 20% of participants' mothers or mothers-in-law preferred breastfeeding, and less than 10% reported that all of the 3 significant family members (partner, mother, and mother-in-law) preferred breastfeeding. The partner's preference for infant formula or mixed feeding (odds ratio [OR], 2.60; 95% confidence interval [CI], 1.43-4.71) or having no preference (OR, 1.64; 95% CI, 1.16-2.30) was strongly associated with higher odds of stopping breastfeeding before 1 month. For every additional family member who preferred breastfeeding, the odds of stopping breastfeeding was reduced by almost 20% (OR, 0.81; 95% CI, 0.68-0.97). However, living with a parent-in-law (OR, 1.45; 95% CI, 1.02-2.07) was also a predictor of early breastfeeding cessation. Knowing someone who had breastfed for ≥ 1 month (OR, 0.64; 95% CI, 0.42-0.97) or having been breastfed as a child (OR, 0.67; 95% CI, 0.45-0.98) significantly lowered the odds of early breastfeeding cessation. The infant feeding preferences of mothers' immediate social network are significantly associated with breastfeeding continuation. Prenatal breastfeeding education programs should involve significant family members to promote breastfeeding. © The Author(s) 2016.

    A laboratory study of older adults with osteoarthritis and their spouses was conducted to examine the unique influence of exposure to suffering on caregivers' risk for impaired psychological and physical health. Spouses' blood pressure (BP) and heart rate (HR) were monitored during 2 tasks designed to capture their partners' suffering. First, spouses watched their partners (and a stranger) carry heavy logs across an 8-ft space for 3 min, a task that elicited pain expression. Second, spouses spoke about their partners' suffering (and also about a typical meal with their partners). Results showed that spouses' BP and HR increased when watching and talking about their partners' suffering, and exposure to a partner's suffering was more physiologically stressful than to a stranger's suffering. These findings suggest that heightened physiological stress caused by exposure to a loved one's suffering may be one pathway to caregivers' increased risk for cardiovascular disease.

    Violence against African American women, specifically intimate partner abuse, has a significant impact on their health and well being. Intimate partner femicide and near fatal intimate partner femicide are the major causes of premature death and disabling injuries for African American women. Yet, despite this, there is a paucity of research and interventions specific and culturally relevant for these women. This article focuses on issues relevant to intimate partner violence and abuse against African American women by examining existing empirical studies of prevalence and health outcomes of intimate partner violence against women in general, plus what limited research there is about African American women, specifically. It includes a discussion of specific recommendations for research, practice, education, and policy to reduce and prevent intimate partner violence against African American women.

    Compensation is a kind of pro-social behavior that can restore a social relationship jeopardized by interpersonal transgression. The effectiveness of a certain compensation strategy (e.g., repaying money, sharing loss, etc.) may vary as a function of the social norm/relationship. Previous studies have shown that two types of norms (or relationships), monetary/exchange and social/communal, differentially characterize people's appraisal of and response to social exchanges. In this study, we investigated how individual differences in preference for these norms affect individuals' perception of others' as well as the selection of their own reciprocal behaviors. In a two-phase experiment with interpersonal transgression, we asked the participant to perform a dot-estimation task with two partners who occasionally and unintentionally inflicted noise stimulation upon the participant (first phase). As compensation one partner gave money to the participant 80% of the time (the monetary partner) and the other bore the noise for the participant 80% of the time (the social partner). Results showed that the individuals' preference for compensation (repaying money versus bearing noise) affected their relationship (exchange versus communal) with the partners adopting different compensation strategies: participants tended to form communal relationships and felt closer to the partner whose compensation strategy matched their own preference. The participants could be differentiated into a social group, who tended to form communal relationship with the social partner, and a monetary group, who tended to form communal relationship with the monetary partner. In the second phase of the experiment, when the participants became transgressors and were asked to compensate for their transgression with money, the social group offered more compensation to the social partners than to the monetary partners, while the monetary group compensated less than the social group in general and showed no

Previous studies have shown that two types of norms (or relationships), monetary/exchange and social/communal, differentially characterize people’s appraisal of and response to social exchanges. In this study, we investigated how individual differences in preference for these norms affect individuals’ perception of others’ as well as the selection of their own reciprocal behaviors. In a two-phase experiment with interpersonal transgression, we asked the participant to perform a dot-estimation task with two partners who occasionally and unintentionally inflicted noise stimulation upon the participant (first phase). As compensation one partner gave money to the participant 80% of the time (the monetary partner) and the other bore the noise for the participant 80% of the time (the social partner). Results showed that the individuals’ preference for compensation (repaying money versus bearing noise) affected their relationship (exchange versus communal) with the partners adopting different compensation strategies: participants tended to form communal relationships and felt closer to the partner whose compensation strategy matched their own preference. The participants could be differentiated into a social group, who tended to form communal relationship with the social partner, and a monetary group, who tended to form communal relationship with the monetary partner. In the second phase of the experiment, when the participants became transgressors and were asked to compensate for their transgression with money, the social group offered more compensation to the social partners than to the monetary partners, while the monetary group compensated less than the social group in general and

    Many companies are beginning to focus on value in their health care purchasing decisions, and some are going beyond value-based purchasing to value-based partnering. Value-based partnering recognizes the interdependencies among stakeholder groups in the health care system and creates a strategic reason for them to exchange information and create long-term strategic alliances. This article discusses the principles of value-based partnering, impediments to practicing it and its future role in the health care system.

    Olive baboons (Papio anubis) do acquire and use intentional requesting gestures in experimental contexts. Individual's hand preference for these gestures is consistent with that observed for typical communicative gestures, but not for manipulative actions. Here, we examine whether the strength of hand preference may also be a good marker of hemispheric specialization for communicative gestures, hence differing from the strength of hand preference for manipulative actions. We compared the consistency of individuals' hand preference with regard to the variation in space of either (i) a communicative partner or (ii) a food item to grasp using a controlled set-up. We report more consistent hand preference for communicative gestures than for grasping actions. Established hand preference in the midline was stronger for gesturing than for grasping and allowed to predict the consistency of hand preference across positions. We found no significant relation between the direction of hand preference and the task. Copyright © 2013 Wiley Periodicals, Inc.

  11. Cooperators benefit through reputation-based partner choice in economic games.

    PubMed

    Sylwester, Karolina; Roberts, Gilbert

    2010-10-23

    Explaining unconditional cooperation, such as donations to charities or contributions to public goods, continues to present a problem. One possibility is that cooperation can pay through developing a reputation that makes one more likely to be chosen for a profitable cooperative partnership, a process termed competitive altruism (CA) or reputation-based partner choice. Here, we show, to our knowledge, for the first time, that investing in a cooperative reputation can bring net benefits through access to more cooperative partners. Participants played a public goods game (PGG) followed by an opportunity to select a partner for a second cooperative game. We found that those who gave more in the PGG were more often selected as desired partners and received more in the paired cooperative game. Reputational competition was even stronger when it was possible for participants to receive a higher payoff from partner choice. The benefits of being selected by a more cooperative partner outweighed the costs of cooperation in the reputation building phase. CA therefore provides an alternative to indirect reciprocity as an explanation for reputation-building behaviour. Furthermore, while indirect reciprocity depends upon individuals giving preference to those of good standing, CA can explain unconditional cooperation.

  12. The Long-Term Effects of Stress on Partner Weight Characteristics.

    2013-01-01

    Recent experimental evidence suggests that stressed males find heavier women more attractive than non-stressed males. The aim of this study is to examine whether these results also appear in actual mating patterns of adults from a national sample. Regression analysis linking partner weight measures to own measures of childhood stress, as measured by mistreatment. Cross-sectional data from the National Longitudinal Study of Adolescent Health, Romantic Partners Sample is used to measure partner weight, childhood stressful events, and socio-demographic characteristics. Childhood experiences of adult mistreatment are retrospectively collected. Men who experienced childhood mistreatment are more likely to have obese female partners during young adulthood. The results are strongest for interactions with social services, adult neglect and physical abuse. We also present novel evidence of the opposite association in similarly stressed women whose male partners are more likely to be thin. These results suggest that preferences for partner characteristics are sensitive to histories of stress and that previously hypothesized patterns occur outside the experimental setting.

    2014-01-01

    Background National population-based studies show that 40%–50% of physical partner violence victims in a 1-year time period are men. However, studies assessing the health concerns related to partner violence victimization tend to focus on women, and none have assessed the health of male physical partner violence victims who sought help for their victimization. Purpose To understand men’s mental and physical health concerns that may be related to partner violence victimization. Methods In 2012–2013, two samples of men—611 physical partner violence victims who sought help and 1,601 men from a population-based sample – completed online questionnaires on their demographics, various types of partner violence victimization, physical health, mental health, and other risks. Data were analyzed using logistic regression, log binomial models, and robust Poisson models in 2013. Results In comparison to the population-based sample of men, male partner violence victims who sought help had significantly poorer health, particularly with regard to post-traumatic stress disorder, depression, high blood pressure, sexually transmitted diseases, and asthma. These differences remained after controlling for sample differences in demographics, substance use, previous traumatic exposure, and social support. Conclusions Practitioners should assess for health problems among partner violence victims and for partner violence victimization among men presenting with health problems. PMID:25442232

    Reluctant Partners examines how the federal government can secure the cooperation it needs to effect national policy goals whtn the implementation process itself empowers potential adversaries. The current battle over how and where to permanently store the nation's high-level nuclear waste poses one of the greatest challenges to federalism since the Civil War. Authority has been legislatively diffused among the federal government, the states, the counties, and certain affected Indian tribes. The situation also epitomizes the conflict that arises when Congress delegates final decisionmaking authority to the bureaucracy. The book contributes to the body of implementation literature by moving past organizational theory to consider issues of governance and leadership. However, it will disappoint the empiricist who sees an opportunity for the application of a theory go by the boards.

  18. Screening for Intimate Partner Violence.

    2016-05-01

    Intimate partner violence (IPV) is a serious concern for women that is associated with significant adverse health effects. Routine screening for IPV is recommended, but there are many barriers to screening that have been identified by providers, including discomfort, lack of training, and not knowing how to respond to a positive screen. This article reviews IPV screening and appropriate techniques for responding to a positive screen. IPV screening best practices include using a systematic protocol, developing a screening script, using a validated screening tool, and considerations for privacy and mandatory reporting. Responding to a positive screen should include acknowledging the experience, asking if the woman desires help, offering support and referrals, encouraging safety planning, and completing additional assessments to determine level of danger and to identify any comorbidities. Using these techniques along with therapeutic communication may increase IPV identification and create an environment in which women feel empowered to get help. © 2016 by the American College of Nurse-Midwives.

    In the theories of team reasoning of Sugden and Bacharach, players are assumed to be motivated in some circumstances to maximize collective rather than individual utilities. An experiment was performed to assess whether preferences underlying such collective payoff maximization occur. An opportunistic sample of 50 undergraduate and graduate students, 7 men and 43 women ages 19 to 42 years (M= 23.0, SD=5.4), expressed preferences among the outcomes of strategic decisions presented in vignettes designed to engage social value orientations of individualism, altruism, competitiveness, equality seeking, or collective preferences. In the vignettes designed to engage collective preferences, and significantly less frequently in the other vignettes, preferences were biased toward outcomes maximizing collective payoffs, and respondents invariably gave team-reasoning explanations for their preferences. These results provide evidence for collective preferences according to theories of team reasoning and empirical support for one of the essential assumptions of these theories.

    Pro-social behaviors are defined as voluntary actions that benefit others. Comparative studies have mostly focused on investigating the presence of pro-sociality across species in an intraspecific context. Taken together, results on both primates and non-primate species indicate that reliance on cooperation may be at work in the selection and maintenance of pro-social sentiments. Dogs appear to be the ideal model when investigating a species’ propensity for pro-sociality in an interspecific context because it has been suggested that as a consequence of domestication, they evolved an underlying temperament encouraging greater propensity to cooperate with human partners. In a recent study, using a food delivery paradigm, dogs were shown to preferentially express pro-social choices toward familiar compared to unfamiliar conspecifics. Using the same set-up and methods in the current study, we investigated dogs’ pro-social preferences toward familiar and unfamiliar human partners. We found that dogs’ pro-social tendencies did not extend to humans and the identity of the human partners did not influence the rate of food delivery. Interestingly, dogs tested with their human partners spent more time gazing at humans, and did so for longer after food consumption had ended than dogs tested with conspecific partners in the initial study. To allow comparability between results from dogs tested with a conspecific and a human partner, the latter were asked not to communicate with dogs in any way. However, this lack of communication from the human may have been aversive to dogs, leading them to cease performing the task earlier compared to the dogs paired with familiar conspecifics in the prior study. This is in line with previous findings suggesting that human communication in such contexts highly affects dogs’ responses. Consequently, we encourage further studies to examine dogs’ pro-social behavior toward humans taking into consideration their potential responses

    Familiarity is attractive in many types of stimuli and exposure generally increases feelings of liking. However, men desire a greater number of sexual partners than women, suggesting a preference for novelty. We examined sex differences in preferences for familiarity. In Study 1 (N = 83 women, 63 men), we exposed individuals to faces twice and found that faces were judged as more attractive on the second rating, reflecting attraction to familiar faces, with the exception that men's ratings of female faces decreased on the second rating, demonstrating attraction to novelty. In Studies 2 (N = 42 women, 28 men) and 3 (N = 51 women, 25 men), exposure particularly decreased men's ratings of women's attractiveness for short-term relationships and their sexiness. In Study 4 (N = 64 women, 50 men), women's attraction to faces was positively related to self-rated similarity to their current partner's face, while the effect was significantly weaker for men. Potentially, men's attraction to novelty may reflect an adaptation promoting the acquisition of a high number of sexual partners.

    2017-01-01

    We present study results regarding soldiers' willingness to conduct posthumous reproduction. Two hundred twelve Israeli soldiers filled in a questionnaire designed to examine their willingness to cryopreserve sperm and evaluate in which familial circumstances they would consent to posthumous reproduction. They ranked the desirability of 46 attributes of a potential mother and a life partner. Findings indicate a relatively high predisposition in favor of posthumous-assisted reproduction; the wishes of soldiers' parents had much more influence on soldiers' willingness to pursue this technology than those of a partner. Soldiers preferred "feminine" jobs for a potential mother that would allow her to dedicate herself to child-rearing. The desired traits of such a mother were rated similarly to partner preferences; however, significant differences were found in attributes that are most related to the potential mother's devotion to maternity. Interpretations of these findings are contextualized in relation to ethical and bereavement considerations.

  11. Population heterogeneity promotes a preference for blind cooperation

    NASA Astrophysics Data System (ADS)

    Perez-Escudero, Alfonso; Friedman, Jonathan; Gore, Jeff

    Game theory--and common sense--recommend to carefully weigh costs and benefits before deciding on a course of action. Yet we often disapprove of people who do so, even when their actual decision benefits us. For example, we prefer people who directly agree to do us a favor over those who agree only after securing enough information to ensure that the favor will not be too costly. Why should we care about how people make their decisions, rather than just focus on the decisions themselves? Hoffman et al. (2015) have shown that such aversion to information gathering may be beneficial when it is strong enough to increase the level of cooperation. Here we show that the same type of aversion arises in heterogeneous populations, but for a different reason: individuals who seek additional information may reveal themselves to be undesirable partners, since they are less likely to cooperate in the future when conditions change. Aversion to information gathering thus facilitates preferential interactions with blind cooperators, who are more favorable partners. Due to this new mechanism the prevalence of such aversion rapidly increases with population diversity, because partner discrimination is more useful in populations which harbor partners of a more varied quality.

    2015-04-01

    Proteins that interact coevolve their structures. When mutation disrupts the interaction, compensation by the partner occurs to restore interaction otherwise counterselection occurs. We show in this study how a destabilizing mutation in one protein is compensated by a stabilizing mutation in its protein partner and their coevolving path. The pathway in this case and likely a general principle of coevolution is that the compensatory change must tolerate both the original and derived structures with equivalence in function and activity. Evolution of the structure of signaling elements in a network is constrained by specific protein pair interactions, by requisite conformational changes, and by catalytic activity. The heterotrimeric G protein-coupled signaling is a paragon of this protein interaction/function complexity and our deep understanding of this pathway in diverse organisms lends itself to evolutionary study. Regulators of G protein Signaling (RGS) proteins accelerate the intrinsic GTP hydrolysis rate of the Gα subunit of the heterotrimeric G protein complex. An important RGS-contact site is a hydroxyl-bearing residue on the switch I region of Gα subunits in animals and most plants, such as Arabidopsis. The exception is the grasses (e.g., rice, maize, sugarcane, millets); these plants have Gα subunits that replaced the critical hydroxyl-bearing threonine with a destabilizing asparagine shown to disrupt interaction between Arabidopsis RGS protein (AtRGS1) and the grass Gα subunit. With one known exception (Setaria italica), grasses do not encode RGS genes. One parsimonious deduction is that the RGS gene was lost in the ancestor to the grasses and then recently acquired horizontally in the lineage S. italica from a nongrass monocot. Like all investigated grasses, S. italica has the Gα subunit with the destabilizing asparagine residue in the protein interface but, unlike other known grass genomes, still encodes an expressed RGS gene, SiRGS1.

    in the 21st century, as more women are employed full-time and couples increasingly share egalitarian values, more women continue employment after their partners have voluntarily retired. However, we know very little about the experiences of this growing population of women. We asked working women with retired partners to share their advice for other women who may face this developmental transition. Open-ended responses from 97 women were analyzed to identify pertinent issues and themes. Four primary content areas were identified: time management, division of household labor, financial planning, and communication. Communication between partners was both a topic of concern as well as the solution suggested to resolve conflicts or differences that may arise when women live with a retired partner. It is expected that future changes in the workforce and improvements in the gender balance within relationships will continue to impact experiences for working women with retired partners.

    2013-09-01

    Latinas recently immigrated to the United States who work in bars or cantinas are at risk of experiencing intimate partner violence (IPV) due to the heavy drinking and sex-related expectations associated with their work and the stigmatized nature of their occupation. We explored the influence of demographic characteristics, substance abuse, and sexual risk behaviors on IPV reported by cantineras for primary and nonprimary sexual partners. Results based on interviews conducted with 669 cantineras indicate that length of residency in the United States and current sexual practices predict IPV perpetrated by both their primary and nonprimary sexual partners. There were also partner-specific predictors of violence related to the substance use and working practices of cantineras. Our findings have implications for understanding the partner violence experienced by this subgroup of stigmatized Latina immigrants and for the ability of current IPV research to capture their experience.

    Many studies in psychology have documented how the behaviour of verbally communicating pairs is affected by social factors such as the partner’s gaze. However, few studies have examined whether physically interacting pairs are influenced by social factors. Here, we asked two partners to exchange forces with one another, where the goal was to accurately replicate the force back onto the other. We first measured an individual’s accuracy in reproducing a force from a robot. We then tested pairs who knowingly exchanged forces whilst separated by a curtain. These separated pairs exchanged forces as two independent individuals would, hence the force reproduction accuracy of partners is not affected by knowingly reproducing a force onto a nonvisible partner. On the other hand, pairs who exchanged forces whilst facing one another consistently under-reproduced the partner’s force in comparison to separated partners. Thus, the force reproduction accuracy of subjects is strongly biased by facing a partner. PMID:27739492

    It was reported recently that male mice lacking brain serotonin (5-HT) lose their preference for females (Liu et al., 2011, Nature, 472, 95–100), suggesting a role for 5-HT signaling in sexual preference. Regulation of sex preference by 5-HT lies outside of the well established roles in this behavior established for the vomeronasal organ (VNO) and the main olfactory epithelium (MOE). Presently, mice with a null mutation in the gene for tryptophan hydroxylase 2 (TPH2), which are depleted of brain 5-HT, were tested for sexual preference. When presented with inanimate (urine scents from male or estrous female) or animate (male or female mouse in estrus) sexual stimuli, TPH2-/- males show a clear preference for female over male stimuli. When a TPH2-/- male is offered the simultaneous choice between an estrous female and a male mouse, no sexual preference is expressed. However, when confounding behaviors that are seen among 3 mice in the same cage are controlled, TPH2-/- mice, like their TPH2+/+ counterparts, express a clear preference for female mice. Female TPH2-/- mice are preferred by males over TPH2+/+ females but this does not lead to increased pregnancy success. In fact, if one or both partners in a mating pair are TPH2-/- in genotype, pregnancy success rates are significantly decreased. Finally, expression of the VNO-specific cation channel TRPC2 and of CNGA2 in the MOE of TPH2-/- mice is normal, consistent with behavioral findings that sexual preference of TPH2-/- males for females is intact. In conclusion, 5-HT signaling in brain does not determine sexual preference in male mice. The use of pharmacological agents that are non-selective for the 5-HT neuronal system and that have serious adverse effects may have contributed historically to the stance that 5-HT regulates sexual behavior, including sex partner preference.

    Female bonobos (Pan paniscus) are characterized as highly affiliative and cooperative, but few studies have quantified the strength and stability of female intra-sexual relationships or explored how variation in social relationships influences cooperation. We measure female social preferences, identify causes of variation in preferences, and test whether variation in social preferences predicts food sharing or coalitionary support. Data were collected over 3 years from females in the Bompusa community at LuiKotale, DRC. We measured genetic relatedness and constructed social preference indices for party association, proximity, grooming, GG-rubbing and aggression. We identified preferred social partners based on permutation tests and measured stability using Mantel tests. We used factor analysis to identify inter-relationships between preference indices and used LMMs to test whether variation in social preferences was explained by relatedness, rank differences, having dependent young or co-residency time. We used GLMMs to test whether variation in social preferences predicted food sharing or coalitionary support. All females had preferred non-kin partners for proximity, grooming or GG-rubbing, but only grooming preferences were stable across years. Association indices were higher among lactating females, and aggression was lower among females with longer co-residency times. The factor analysis identified one factor, representing proximity and GG-rubbing preferences, labeled behavioral coordination. Dyads with higher levels of behavioral coordination were more likely to share food. Female bonobos exhibit stable, differentiated grooming relationships outside of kinship and philopatry. Females also exhibit flexible proximity and GG-rubbing preferences that may facilitate cooperation with a wider range of social partners. © 2017 Wiley Periodicals, Inc.

    Intimate partner violence (IPV) is known to be prevalent among therapy-seeking populations. Yet, despite a growing understanding of the dynamics of IPV and of the acceptability of screening, universal screening practices have not been systematically adopted in family therapy settings. A rapidly growing body of research data-almost entirely conducted in medical settings-has investigated attitudes and practices regarding universal screening for IPV. This article is a systematic review of the IPV universal screening research literature. The review summarizes literature related to IPV screening rates and practices, factors associated with provider screening practice, the role of training and institutional support on screening practice, impact of screening on disclosure rates, client beliefs and preferences for screening, and key safety considerations and screening competencies. Implications for family therapy and recommendations for further inquiry and screening model development are provided. © 2011 American Association for Marriage and Family Therapy.

    As the current revolution in communication is underway, quantum teleportation can increase the level of security in quantum communication applications. In this paper, we present a quantum teleportation procedure that capable to teleport either accelerated or non-accelerated information through different quantum channels. These quantum channels are based on accelerated multi-qubit states, where each qubit of each of these channels represents a partner. Namely, these states are the W state, Greenberger-Horne-Zeilinger (GHZ) state, and the GHZ-like state. Here, we show that the fidelity of teleporting accelerated information is higher than the fidelity of teleporting non-accelerated information, both through a quantum channel that is based on accelerated state. Also, the comparison among the performance of these three channels shows that the degree of fidelity depends on type of the used channel, type of the measurement, and value of the acceleration. The result of comparison concludes that teleporting information through channel that is based on the GHZ state is more robust than teleporting information through channels that are based on the other two states. For future work, the proposed procedure can be generalized later to achieve communication through a wider quantum network.
