    Ganglion cysts are common pseudocystic masses, whereas those arising from the temporomandibular joint (TMJ) are rare entities. We report a case of ganglion cyst of the right TMJ with symptomatic bilateral TMJ internal derangement in a 24-year-old man. Disk repositioning using bone anchors and excision of the ganglion cyst were performed. A unique characteristic of inflammatory infiltrates was revealed in the specimen, and the relationship between these 2 distinct entities and probable pathogenesis of infectious involvement are discussed.

    The purpose of this pilot project was to develop, administer and assess a brief male-focused and behavioural-driven condom promotion programme for young adult African American males in an urban setting. To achieve the aims of this study, linkages with local community centres were initially fostered and both quantitative and qualitative research methods were employed. Based on relevant tenets of the social cognitive theory and the stages of change model, a series of focus groups were conducted among the target population, recruited from non-traditional urban settings, to identify and further explore their perceived condom use barriers and facilitators in order to support programme development. Specifically, the topical items addressed those young men’s perceptions of sexuality and condom use within three broad contexts: general sexual behaviours, condom use behaviours, and the relationship between condoms and substance use. The focus group discussions were audiotaped and the transcribed data summarized and analysed based on those thematic topics. The findings revealed that significant myths, misconceptions and knowledge gaps exist regarding HIV/STD-related prevention, condom promotion and substance use. The findings imply that there is a critical need to develop target group suitable condom promotion programmes in order to successfully promote, foster and sustain condom use among high-risk populations.

    The purpose of this study was to investigate whether the functional movement screen (FMS) could predict running injuries in competitive runners. Eighty-four competitive male runners (average age = 20.0 ± 1.1 years) participated. Each subject performed the FMS, which consisted of 7 movement tests (each score range: 0-3, total score range: 0-21), during the preseason. The incidence of running injuries (time lost because of injury ≤ 4 weeks) was investigated through a follow-up survey during the 6-month season. Mann-Whitney U-tests were used to investigate which movement tests were significantly associated with running injuries. The receiver-operator characteristic (ROC) analysis was used to determine the cutoff. The mean FMS composite score was 14.1 ± 2.3. The ROC analysis determined the cutoff at 14/15 (sensitivity = 0.73, specificity = 0.54), suggesting that the composite score had a low predictability for running injuries. However, the total scores (0-6) from the deep squat (DS) and active straight leg raise (ASLR) tests (DS and ASLR), which were significant with the U-test, had relatively high predictability at the cutoff of 3/4 (sensitivity = 0.73, specificity = 0.74). Furthermore, the multivariate logistic regression analysis revealed that the DS and ASLR scores of ≤3 significantly influenced the incidence of running injuries after adjusting for subjects' characteristics (odds ratio = 9.7, 95% confidence interval = 2.1-44.4). Thus, the current study identified the DS and ASLR score as a more effective method than the composite score to screen the risk of running injuries in competitive male runners.

    We aimed to estimate the incidence of a first episode of problem gambling among Swedish 16-24 year-olds by demographic and socio-economic characteristics, and to compare the incidence between 16-24 and 25-44 year-olds, and between young women and men. Other aims were to estimate the proportions of recovery and incidence in recurrent problem gambling, and prevalence of problem gambling among 16-44 year-olds in Sweden. We selected 4,358 participants aged 16-44 from the nationally representative Swedish Longitudinal Gambling Study in 2008/2009 and 2009/2010. The primary outcome measure was a first episode of problem gambling during 12 months before the follow-up as measured by the Problem Gambling Severity Index among participants without a history of problem gambling at baseline. The incidence proportion of a first episode of problem gambling among 16-24 year-olds was 2.26% (95% confidence interval 1.52-3.36); three times lower among females (1.14; 0.42-3.07%) than males (3.32; 2.19-5.01%). Young age and household financial problems were associated with first episode problem gambling among young women. Among 25-44 year-olds, the incidence proportion of a first episode of problem gambling was 0.81% (0.41-1.56). Recovery from problem gambling was high, in particular among females. Individual transitions from problem gambling to recovery and to recurrent problem gambling, between baseline and follow-up, were common regardless of age. This study adds further evidence to research suggesting that there is a high mobility in and out of problem gambling over time on an individual level. The high incidence of first episode problem gambling among youth in Sweden stresses the importance of prevention of problem gambling at an early age.

    to study the most frequent death causes between young people during 1991 to 2000. We worked at the Epidemiological Research Center of the Buenos Aires Academy of Medicine, with all the country's death dates certified by the Ministry of Health. Argentine young population (10 to 24 years old) was of about 10,000,000 people, after the increase of 15% during the studied period. The population studied were all violent causes of death of people between 10 to 24 years old, of Argentina, since 1991 to 2000. The violent causes of death studied were: Accident (other than traffic), traffic accidents, suicide, homicide, between 10-14 year old, 15-19 year old and 20-24 year old, male and female youngsters. Mortality rates were calculated on yearly basis per province and per country. Of 100% of death causes among 10-24 years old adolescents: 15% were accidents (non traffic), 14,6 traffic accidents, 10,1% homicides and 9,1% were suicides. Mortality rates were higher for males, in all ages and during all the period. We observed an increase in external causes of death during 1991 to 2000. Mortality rates of homicide and suicide increased for males between 1991 and 2000. Adolescents (15-19 year old) and male gender are risk factors for external causes of death (accidents, aggression and suicide). The results of this study showed that mortality by violent causes should be a priority problem for the Public Health and for all the community.

    To describe the sexual behaviors and practices of Spanish adolescents and young adults according to gender. Information was gathered by means of a questionnaire administered in participants' homes in the presence of an interviewer. A random sample was used, consisting of 2,171 adolescents and young adults of both sexes, ranging in age from 14 to 24 years old. The participants were from three distinct regions of Spain: Galicia, Madrid, and Andalusia. A total of 1,439 participants (66.3%) reported having been sexually active in the previous 6 months, with no statistically significant differences between male (66.4%) and female (66.2%) respondents. However, significant differences were found between males and females in the following variables: anal intercourse was reported by a higher proportion of males than females, the number of sexual partners reported by females was lower than that reported by males and the frequency of vaginal intercourse reported by females was higher than that reported by males. Condom use in anal intercourse and oral sex was more frequently reported by males than by females. The results of this study indicate that sexual behavior differs between genders, with females having a lower number of sexual partners and more frequently using a condom in vaginal intercourse but less frequently in oral sex and anal intercourse. In view of these data, we believe that gender should be taken into account when designing and implementing preventive interventions.

    Background While risk factors for HPV infections in young women are well-defined, the risk associated with meeting male sex partners via the internet is unclear. Methods We analyzed cross-sectional data from 282 18-24-year old women who reported using Internet dating websites in the past year. Women were mailed vaginal self-sampling kits for PCR-based HPV genotyping (including 19 oncogenic types) and sexual behavior and health history questionnaires. Generalized linear models were used to evaluate risk factors for prevalent oncogenic HPV infections. Results 35% of women reported having met a male sex partner via the Internet in the past 6 months, and 42% reported a history of HPV vaccination. The prevalence of oncogenic HPV infection was 37%, and 9% of women tested positive for HPV-16 or HPV-18. Having met a male sex partner via the Internet in the past 6 months was not significantly associated with oncogenic HPV infection. In multivariate analyses, variables associated with an increased likelihood of oncogenic HPV infection included male partners in the past 6 months who were reported to have ≥1 concurrent partnership (adjusted prevalence ratio [aPR]=1.51,95%CI:1.11-2.06) and not always using condoms with male partners in the past 6 months (aPR=1.86,95%CI:1.05-3.30). Self-reporting a history of receiving ≥1 dose of HPV vaccine was inversely associated with testing positive for HPV-16 or HPV-18 (aPR=0.39,95%CI:0.16–0.97). Conclusions While measures of recent sexual behavior were associated with prevalent oncogenic HPV infection, male partners met online were not associated with an increased likelihood of infection in this cohort of young women.

This was the patient's seventh priapism, with his most recent attendance 1 week previously for which he underwent a distal cavernosal shunt. He admitted to taking several recreational drugs, including marijuana and cocaine, during the preceding few days, in addition to the long-term use of the oral anabolic steroid oxandrolone. He had no family history of sickle cell disease or trait. On examination, a tensely erect penis was noted. A diagnosis of stuttering priapism was made and 750 mL of blood subsequently drained via a distal corporoglandular shunt resulting in successful detumescence. 2016 BMJ Publishing Group Ltd.

    Introduction. Simultaneous bilateral quadriceps tendon ruptures (SBQTR) are uncommon knee injuries and most frequently occur in male patients, over 50 years of age. It can be associated with one or more predisposing risk factors like obesity, steroids use, and hyperparathyroidism. The main focus of this paper is to review SBQTR in obese patients. Case Report. We are reporting the youngest patient in the literature to date, a 24-year-old obese male patient, who presented to the emergency department complaining of bilateral knee pain and inability to walk after a fall during a basketball game. His clinical examination revealed the presence of a palpable suprapatellar gap and loss of knee extension bilaterally. Magnetic resonance imaging (MRI) confirmed that both of his quadriceps tendons were ruptured. A day after his diagnosis, the patient underwent successful operative repair followed by rehabilitation. At the two-year follow-up, the patient had full strength of both quadriceps muscles with no extension lag. Conclusion. The diagnosis of SBQTR can be challenging. Early diagnosis and treatment are associated with better functional outcome compared to delayed treatment. Physicians should have a high index of clinical suspicion in order not to miss such an injury and achieve favourable outcomes. PMID:27840757

    An extra tooth to the normal formula of teeth sequence in any region of dental arch is regarded as Supernumerary teeth (ST). The reasons are still not clearly known, one of them being dichotomy of tooth bud, but the more accepted reason is the hyperactivity theory. Supernumerary teeth are present more in permanent dentition than in primary dentition and can present as a single entity or multiple, unilaterally or bilaterally, impacted or erupted, in either or both the dental arches. This article discusses the supernumerary teeth in detail with a case discussion of a non-syndromic 24-year-old girl, with six ST (bicuspids) present in all the four quadrants. In the mandible, ST’s showed a classical clustered flower like presentation. The interesting feature in the presented case was the sequential orthopantomographs taken at various ages of the patient that showed continuous development of STs in all four quadrants, thus pointing to the theory of hyperactive dental lamina or atavism. An electronic search was conceded in PubMed, Cochrane Library and google scholar databases, and articles dated between December 1932 and December 2012 were selected to review the occurrence patterns of supernumerary teeth in non-syndromic cases.

  14. The invasive annual cheatgrass increases nitrogen availability in 24-year-old replicated field plots.

    Previous studies comparing invaded and non-invaded sites suggest that cheatgrass (Bromus tectorum L.) causes soil N cycling to increase. Unfortunately, these correlative studies fail to distinguish whether cheatgrass caused the differences in N cycling, or if cheatgrass simply invaded sites where N availability was greater. We measured soil C and N concentrations and net and gross N-cycling rates on 24-year-old replicated field plots in a sagebrush-steppe ecosystem that had been plowed, fumigated, and seeded to different plant communities in 1984. Laboratory assays of soil collected throughout the soil profiles (0-60 cm) showed that soil NO3 (-), organic C and N, and net N mineralization, net nitrification, and soil respiration rates were all greater beneath cheatgrass than in sagebrush-perennial grass plots. In surface soils (0-10 cm), field and lab assays on five sampling dates during 2 years showed gross N mineralization, net N mineralization, and net nitrification rates were all faster beneath cheatgrass than in sagebrush-perennial grass plots. Modeling analyses based on soil respiration and gross N-cycling rates suggest that cheatgrass provides soil microbes with lower C:N substrates and that this could explain the faster N-cycling rates beneath cheatgrass. This is the first long-term replicated field study to conclusively show that cheatgrass created greater soil organic N pool sizes and stimulated N-cycling rates compared to similar-aged stands of sagebrush and native perennial grasses. Increased N-cycling rates may represent a positive plant-soil feedback that promotes continued dominance by cheatgrass, even in the absence of soil disturbance or fire.

    Background Adolescent reproductive health has not continued to receive the attention it deserves since the start of the HIV epidemic. In South Africa, high numbers of adolescent women report pregnancies that are unwanted and yet few have accessed available termination of pregnancy services. Enabling contraception use is vital for meeting the goals of HIV prevention. Methods A nationally representative survey of South African 15–24 year olds was undertaken. Participants completed a questionnaire on sexual behaviour and provided an oral fluid sample for HIV testing. Analysis of the data was restricted to women (n = 6217), particularly those who reported being sexual active in the last 12 months (n = 3618) and was conducted using svy methods in the program STATA 8.0 to take account of sampling methods. Univariate and multivariate analyses were conducted to explore factors associated with contraceptive use. Results Two thirds of all women reported having ever been sexually active and among these 87% were sexually active in the past 12 months. Among women who reported currently being sexually active, 52.2% reported using contraceptives. There was evidence of association between contraceptive use and being employed or a student (vs unemployed); fewer sex partners; type of last sex partner; having talked to last partner about condom use and having ever been pregnant. Conclusion Specific emphasis must be placed on encouraging young women to use contraceptive methods that offer protection against pregnancy and STIs/HIV. Our consistent finding of a relationship between discussing condom use with partners and condom use indicates the importance of involvement of male partners in women's contraceptive decisions.

    Billions of dollars are spent annually in the United States in the largely unregulated market of dietary supplements. Many of these supplements are marketed as weight-loss and athletic-performance-enhancement products. The association of various ephedra-containing products with adverse cardiovascular events has led to a ban on the sale of these products by the U.S. Food and Drug Administration. The result has been the emergence of new formulations marketed for weight loss and athletic-performance enhancement that are “ephedra-free” but contain other sympathomimetic substances, the safety of which has not been established. We present the case of a previously healthy 24-year-old man who presented with an ST-segment-elevation myocardial infarction (STEMI) within hours of taking the ephedra-free product Nutrex Lipo-6x®. Emergent coronary angiography revealed the presence of extensive, diffuse thrombus in the left anterior descending coronary artery. The patient had no risk factors for coronary artery disease or myocardial infarction; this includes the absence of a hypercoagulable state and the absence of a history of illicit drug use. This case of STEMI—associated as it is with the use of a synephrine-containing product by a person without risk factors for coronary artery disease—is to our knowledge the 1st reported in the literature. We discuss the patient's evaluation and clinical course, and we review the literature with respect to synephrine-containing dietary supplements. On the basis of synephrine's chemical composition and mechanism of action, we propose a direct association between this patient's use of Nutrex Lipo-6x® and his STEMI. PMID:20069086

    This study investigated the developmental stages of third molars in relation to chronological age and compared third molar development according to location and gender. A retrospective analysis of panoramic radiographs of 2490 patients aged between 6 and 24 years was conducted, and the developmental stages of the third molars were evaluated using the modified Demirjian's classification. The mean age, standard deviation, minimal and maximal age, and percentile distributions were recorded for each stage of development. A Mann-Whitney U test was performed to test the developmental differences in the third molars between the maxillary and mandibular arches and between genders. A linear regression analysis was used for assessing the correlation between the third molar development and chronological age. The developmental stages of the third molars were more advanced in the maxillary arch than the mandibular arch. Males reached the developmental stages earlier than females. The average age of the initial mineralization of the third molars was 8.57 years, and the average age at apex closure was 21.96 years. The mean age of crown completion was 14.52 and 15.04 years for the maxillary and the mandibular third molars, respectively. The developmental stages of the third molars clearly showed a strong correlation with age. The third molars developed earlier in the upper arch than the lower arch; further, they developed earlier in males than in females.

    There is increasing incidence and prevalence of chronic kidney disease worldwide. The developing countries including Nigeria are facing greater challenges because of the prevailing poverty and high burden of infectious diseases. There are various prevalent co-morbid conditions that influence and are influenced by the status of the kidney function of the patient. These conditions pose some peculiar challenges and management of the challenges will determine the outcome. The aim of this report is to highlight the chalIenges of pregnancy in women with chronic kidney disease and possible outcome. We report a 24 years Nigerian woman diagnosed with chronic kidney disease who presented with 10 weeks gestation and deteriorating kidney function. Her management was associated with various challenges including non adherance to medications and not regular to follow up visits. She later developed ecclampsia and had intra uterine fetal death. She had various interventional measures including haemodialysis. She recovered kidney function appreciably but has defaulted follow up since discharge.

    Despite advances in HIV medicine, adherence presents as a barrier to effective treatment for youth. We designed this study to assess medication knowledge, adherence, and factors affecting adherence in youth with HIV. Participants were 72 youth ages 13 to 24 years with perinatally or behaviorally acquired HIV. Demographic data were collected and a self-report adherence interview was administered. Interviews were audio-recorded to allow for qualitative data analysis. Self-reported adherence varied depending on the framing of questions, with participants reporting greater adherence when asked how many doses they had missed within the past 7 days compared to results from a 7-day recall interview. At least 74% of the sample said they sometimes forgot to take their medication. A taxonomic approach to the qualitative analysis revealed internal and external facilitators and barriers to adherence. Findings suggest a need for education and provider support to include strategies to improve adherence. Copyright © 2016 Association of Nurses in AIDS Care. Published by Elsevier Inc.

    We describe a profoundly intellectually disabled 24-year-old man with Wolf-Hirschhorn syndrome, left hemiplegia, epilepsy, atrophy of the right cerebral hemisphere, and dilatation of the right ventricle. The patient had a small ventricular septal defect, was wheelchair bound, and totally dependent. He had no speech, but vocalized to show his feelings. In this patient, the del(4)(p15) was subtle and arose due to the inheritance of a recombinant chromosome (4) from a maternal pericentric inversion - 46,XX,inv(4)(p15.32q35).

    Most women begin sexual activity as teenagers but nearly 20% of women in France younger than 25 years rely on less effective contraceptive methods (condoms or methods such as withdrawal or periodic abstinence). We sought to analyze the association with less effective contraception among women aged 15-24 years in France and communication about sex and contraception with their parents. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS AND MAIN OUTCOME MEASURES: The analyses focused on 713 sexually active women who did not currently want a child, were using contraception, and were interviewed in 2010 in a national cross-sectional probability survey (FECOND) when they were 15-24 years old. Associations between the use of less effective contraception, social and demographic characteristics, sexual activity, health characteristics, and communication with parents and friends about sexuality and contraception were tested with logistic regression models by age group. Less effective contraception (condoms, and barrier or natural methods) is used more often by younger women: 27.5% of 15-19 year olds and 14.7% of 20-24 year olds (p<.001). After adjustment for demographic characteristics and aspects of their sex lives (regularity and frequency of intercourse), women who reported difficulty discussing contraception and sex with their mothers at age 15 were more likely than those with easier communication to use less effective contraception (for those 15-19, odds ratio=1.97, 95% confidence interval (CI) [0.94, 4.10] and for those 20-24, 2.36 [1.31, 4.26]). Difficulty in communicating with their parents, especially their mothers, about sex, is associated with young women's choice of less effective contraception. Copyright © 2017.

    The purpose of this case report is to relate an episode of movement impairment at the cuboid calcaneal articulation leading to symptoms of iliotibial band (ITB) syndrome. An explanation of the etiology and clinical diagnosis in relation to the differential diagnosis, treatment techniques, and patient outcomes are described. The 24-year-old female tri-athlete reported pain at Gerdy’s tubercle and lateral femoral condyle areas occurring within 2 miles of a run. VAS score was 6/10 for the running activity and the lower extremity functional scale (LEFS) score was 93% (74/80). Over the previous 2 years, the ITB symptoms had failed to resolve with extensive conservative treatment at the knee. On weight bearing, the patient demonstrated pain free limitation of active midtarsal pronation more than supination, which correlated with a decrease in passive internal rotation of the cuboid. Symptoms resolved after one cuboid whip manipulation and the patient was able to run pain free. Post-manipulation treatment consisted of two more sessions, which included motor retraining for weight bearing active midtarsal pronation and supination. LEFS was 100% (80/80) and VAS 0/10 with running greater than 10 miles. While causality cannot be inferred from a single case, this report may foster further investigation regarding the differential diagnosis and treatment of a hypomobile cuboid. PMID:24421625

    Online dietary assessment tools offer a convenient, low cost alternative to traditional dietary assessment methods such as weighed records and face-to-face interviewer-led 24-h recalls. INTAKE24 is an online multiple pass 24-h recall tool developed for use with 11–24 year-old. The aim of the study was to undertake a comparison of INTAKE24 (the test method) with interviewer-led multiple pass 24-h recalls (the comparison method) in 180 people aged 11–24 years. Each participant completed both an INTAKE24 24-h recall and an interviewer-led 24-h recall on the same day on four occasions over a one-month period. The daily energy and nutrient intakes reported in INTAKE24 were compared to those reported in the interviewer-led recall. Mean intakes reported using INTAKE24 were similar to the intakes reported in the interviewer-led recall for energy and macronutrients. INTAKE24 was found to underestimate energy intake by 1% on average compared to the interviewer-led recall with the limits of agreement ranging from minus 49% to plus 93%. Mean intakes of all macronutrients and micronutrients (except non-milk extrinsic sugars) were within 4% of the interviewer-led recall. Dietary assessment that utilises technology may offer a viable alternative and be more engaging than paper based methods, particularly for children and young adults. PMID:27294952

    Body size is postulated to modulate type 1 diabetes as either a trigger of islet autoimmunity or an accelerator to clinical onset after seroconversion. As overweight and obesity continue to rise among children, the aim of this study was to determine whether human leukocyte antigen DQ (HLA-DQ) genotypes may be related to body size among children genetically at risk for type 1 diabetes. Repeated measures of weight and height were collected from 5969 children 2-4 years of age enrolled in The Environmental Determinants of Diabetes in the Young prospective study. Overweight and obesity was determined by the International Obesity Task Force cutoff values that correspond to body mass index (BMI) of 25 and 30 kg m(-)(2) at age 18. The average BMI was comparable across specific HLA genotypes at every age point. The proportion of overweight was not different by HL A, but percent obesity varied by age with a decreasing trend among DQ2/8 carriers (P for trend=0.0315). A multivariable regression model suggested DQ2/2 was associated with higher obesity risk at age 4 (odds ratio, 2.41; 95% confidence interval, 1.21-4.80) after adjusting for the development of islet autoantibody and/or type 1 diabetes. The HLA-DQ2/2 genotype may predispose to obesity among 2-4-year-old children with genetic risk for type 1 diabetes.

    There is a paucity of work documenting the influence of patterns of care on survival for teenagers and young adults with primary central nervous system tumours. Therefore, the aim of this study was to undertake a detailed assessment examining any changes in the patterns of care over time and how these related to survival outcomes for 16-24 year olds diagnosed with a primary central nervous system tumour between 1990 and 2009. We used high-quality data from one population-based cancer registry in Yorkshire, UK to describe primary central nervous system tumours in teenagers and young adults (16-24 years) diagnosed between 1990 and 2009. The Birch classification scheme was used to identify differences by tumour subgroup. Incidence, patterns of care and survival trends were described using Poisson and Cox regression. There were 163 cases comprising 98 astrocytomas, 17 'other gliomas', 14 ependymomas, 11 medulloblastomas and 23 'other intracranial and intraspinal neoplasms' yielding an overall incidence of 18.1 million person-years. Care varied significantly over time and by principal treatment centre (Leeds 77%, Hull 23%), co-ordinating specialty (neurosurgery 53%, clinical oncology 22%, paediatrics 17%, other adult services 8%) and treatment received. Cox regression showed no significant difference in survival by age, gender, treatment centre, level of deprivation, year of diagnosis or co-ordinating specialty, but a significant difference by tumour grade and diagnostic group. Survival improved for all diagnostic groups except astrocytoma, although only the medulloblastoma group showed a significant change over time. The lack of any significant improvement in survival over time in most diagnostic groups warrants further investigation and provides justification for a more collaborative regional approach to the care of central nervous system tumours, perhaps through the development of regional guidelines for this unique population.

    Escalating wildfire in subalpine forests with stand-replacing fire regimes is increasing the extent of early-seral forests throughout the western USA. Post-fire succession generates the fuel for future fires, but little is known about fuel loads and their variability in young post-fire stands. We sampled fuel profiles in 24-year-old post-fire lodgepole pine (Pinus contorta var. latifolia) stands (n = 82) that regenerated from the 1988 Yellowstone Fires to answer three questions. (1) How do canopy and surface fuel loads vary within and among young lodgepole pine stands? (2) How do canopy and surface fuels vary with pre- and post-fire lodgepole pine stand structure and environmental conditions? (3) How have surface fuels changed between eight and 24 years post-fire? Fuel complexes varied tremendously across the landscape despite having regenerated from the same fires. Available canopy fuel loads and canopy bulk density averaged 8.5 Mg/ha (range 0.0-46.6) and 0.24 kg/m(3) (range: 0.0-2.3), respectively, meeting or exceeding levels in mature lodgepole pine forests. Total surface-fuel loads averaged 123 Mg/ha (range: 43-207), and 88% was in the 1,000-h fuel class. Litter, 1-h, and 10-h surface fuel loads were lower than reported for mature lodgepole pine forests, and 1,000-h fuel loads were similar or greater. Among-plot variation was greater in canopy fuels than surface fuels, and within-plot variation was greater than among-plot variation for nearly all fuels. Post-fire lodgepole pine density was the strongest positive predictor of canopy and fine surface fuel loads. Pre-fire successional stage was the best predictor of 100-h and 1,000-h fuel loads in the post-fire stands and strongly influenced the size and proportion of sound logs (greater when late successional stands had burned) and rotten logs (greater when early successional stands had burned). Our data suggest that 76% of the young post-fire lodgepole pine forests have 1,000-h fuel loads that exceed

    Despite male breast cancer is rare in occurrence, it is a serious problem. In 2012, 130 men in Ukraine got breast cancer that constituted 0.74% from all patients with mentioned pathology detected in the course of year. Every year in Ukraine approximately 100 men die from breast cancer. Still many aspects of male breast cancer remain unstudied. It occurs since information about mentioned disease is mainly based on retrospective analysis of small groups. Treatment of men, who got breast cancer, is based on knowledge, which has been obtained in treatment of women with this pathology. This article is based on the results of analysis of 168 cases of breast cancer in men, who have been examined and treated in the period from 1956 to 2012. In paper the peculiarities of clinical manifestations of male breast cancer have been determined, the optimal volume of diagnostic procedures in men with suspicion of breast cancer has been established, the mammographic signs have been detected and the possible histological variants of disease have been determined, clinical course peculiarities of male breast cancer have been defined, the most essential factors of prognosis of the disease have been fixed. Furthermore, in article optimal volume of surgical treatment of male breast cancer has been substantiated, the role and place of radiotherapy in treatment of this pathology has been determined. It has been proved that adjuvant polychemotherapy should be applied to the patients with male breast cancer independently from stage of process. Also optimal schemes of this kind of treatment have been determined. The efficacy of hormonal therapy with antiestrogen in patients with positive receptors of steroid hormones and at presence of unfavorable prognostic factors of disease has been demonstrated. The inefficiency of orchiectomy as one of the widespread kinds of hormonal therapy of male breast cancer has been defined.

    Hemiplegic migraine is a rare and complex disease, characterized by migraine with a reversible motor aura. Hemiplegic migraine can be easily misdiagnosed at its first presentation with an atypical severe form of migraine, a stroke, multiple sclerosis, metabolic disorders, conversion disorder or an epilepsy. We present the case of a young 24-year-old male patient, who since the age of 4 years had been having multiple episodes of migraine associated with hemiparesis, paraesthesia, prolonged somnolence, aphasia and confusion. We review the literature and discuss important diagnostic findings in hemiplegic migraine to help establishing a prompt diagnosis. PMID:27790126

This unusual subtype has a generally favorable prognosis, although several cases have been described in adults with increased aggressiveness and a risk of metastases even death. So far, merely ten cases of secretory breast carcinoma with metastatic axillary lymph node in male were reported. Here, we describe the eleventh case, a 24-years-old male who presented with a painless mass in the right breast was diagnosed to be “secretary breast carcinoma”, and subsequently underwent modified radical mastectomy and adjuvant chemotherapy.

    2012-01-01

    Aim: To evaluate the clinical profile and management of 46 XX Congenital Adrenal Hyperplasia (CAH) patients presenting with severe virilization and assigned a male gender. Materials and Methods: Of 173 children diagnosed with CAH at the Pediatric Intersex Clinic since 1980, seven children with CAH presented late with severe virilization and were reared as males. All of them were assigned the male sex with removal of the female adnexa. Six were treated with male genitoplasty. Appropriate hormonal supplementation was offered after puberty. Results: The mean age at presentation was 14.2 years (7 – 21). Six patients had presented after puberty, only one at seven years of age. Staged male genitoplasty comprising of chordee correction, male urethroplasty, and bilateral testicular prosthesis was performed. The female adnexa (uterus, ovaries, most of the upper vagina, and the fallopian tubes) were removed. The mental makeup was masculine in six and bigender in one. Bilateral mastectomy was performed at puberty in all. Hormonal treatment comprised of glucocorticoids and testosterone. Six patients were comfortable with the outcome of the masculinizing genitoplasty. One had a short-sized phallus. One had repeated attacks of urinary tract infection arising from the retained lower vaginal pouch. Social adjustments were good in all, except in one who had a bigender mental makeup. Conclusion: CAH patients with severe virilization presenting late and reared as males are extremely rare. However, the assigned gender can be retained adequately as males, meeting the socioeconomic compulsions of the society. The results are satisfactory following appropriate surgical procedures and hormonal supplementation. PMID:23226638

    2008-06-01

    Apathetic hyperthyroidism is an uncommon presentation of thyrotoxicosis that is most commonly observed in elderly individuals. A small number of cases, however, have been observed in young adults-all of whom were female. We describe a case of apathetic hyperthyroidism due to painless thyroiditis in a 23-year-old active duty male, who presented with a 1-month history of change in behavior characterized by poverty of speech and disinterest in his surrounding environment. Initial evaluation for neuropsychological disorders was negative. Thyroid function tests showed a thyrotoxic state. Results of thyroid antibody testing and a thyroid uptake and scan supported the diagnosis of painless thyroiditis. The patient's presenting symptoms were attributed to apathetic thyrotoxicosis and he was treated supportively. His speech and social involvement slowly improved. Although uncommon in young adults, we recommend that apathetic hyperthyroidism be considered in the differential diagnosis of withdrawn social behavior and subsequently investigated with thyroid function tests.

    In this study, we describe nine patients with 47,XYY presenting with male infertility. All patients were subjected to history taking, clinical examination, duplex ultrasonographic examination of the scrotum, endocrinological investigations and cytogenetic analysis of peripheral lymphocytes. Two patients tried intracytoplasmic sperm injection (ICSI). Our results showed that seven patients were oligospermic and two patients were azoospermic. Bilateral varicocele was detected in seven patients. The hormonal levels in the majority of the patients were within normal range. Two patients showed improvement after varicocelectomy. The wife of one of the oligospermic patients became successfully pregnant after the first trial of ICSI. In conclusion, this report suggests that patients with XYY may present with primary infertility and may show oligospermia and nonobstructive azoospermia. Careful clinical, ultrasonographic, endocrinological and cytogenetic examinations should be a part of their diagnostic work-up for the proper management of these patients. In addition, ICSI may be a hope for some of these patients.

    Ischemic stroke is a rare event in young adults. We report on a 24-yr-old pilot with cerebral infarction of undetermined etiology, temporally associated with chain smoking. The patient exhibited dysphasia, stupor (confused consciousness), and right facial-nerve palsy. Computed-tomography revealed a low-density area in the left insular cortex. Cerebroangiography showed severe stenosis in a branch of the left middle cerebral artery. After admission, the patient made a rapid and uneventful recovery within 72 h. MRI showed an area of hyperintensity on T2-weighted images 2 mo after the attack. Based on the hyperintense area on FLAIR (fluid attenuated inversion recovery sequence) images obtained in MRI performed 10 mo after the attack, we diagnosed a cerebral infarction. In the Japan Air Self-Defense Force, cerebral infarction is an aeromedically disqualifying condition. However, in the evaluation 2 mo after the attack, differentiation from reversible ischemic neurological deficit was difficult. We discuss the criteria used for diagnosis and the risk factors for cerebral infarction in young adults, as well as the aeromedical disposition of young pilots.

    Podoconiosis is a non-infectious tropical disease caused by exposure of bare feet to irritant alkalic clay soils. This causes an asymmetrical swelling of the feet and lower limbs due to lymphoedema. This swelling is called “elephantiasis” and may lead to severe disability of the patient. It is found in areas of tropical Africa, Central and South America and north-west India, where such soils coexist with high altitude, high seasonal rainfall and low income. Social stigmatization of people with the disease is widespread and economic losses are enormous. Podoconiosis is unique in being an entirely preventable non-communicable tropical disease. However, so far it has received little attention from health care policy makers. PMID:23042845

    Burkitt's lymphoma is a very aggressive type of B-cell NHL with replication approaching 100%. Primary gastrointestinal lymphoma is rare. In our case, a 24-year-old male initially presented with symptomatic anemia. He was initially evaluated with colonoscopy and EGD, both of which were unremarkable. A capsule endoscopy was then performed to further evaluate his significant anemia which revealed friable inflamed ulcerated mass in the jejunum. A push enteroscopy was then performed to obtain tissue from the jejunal mass. Biopsy results and immunohistochemical stains were consistent with Burkitt's lymphoma. PET/CT scan revealed only jejunal involvement. Treatment consisted of bowel resection prior to chemotherapy due to concern for perforation with chemotherapy. Patient achieved complete remission after the treatment. PMID:27672459

Even as DCIS has been reported in conjunction with gynecomastia in the same breast, we report an unusual case of a 62-year-old Caucasian male, with no family history of breast cancer, who presented with symptomatic side gynecomastia, and was incidentally found to have DCIS in a completely asymptomatic left breast. To the best of our knowledge, this case is the first report in literature of asymptomatic, incidentally discovered DCIS in a male patient. PMID:22530182

    Granular Cell Tumour (GCT), also known as Abrikossoff’s tumour is a rare neural tumour, mostly benign and solitary but rare malignant and multifocal occurrence are also reported. Location of tumour varies widely within body with tongue, skin and subcutaneous tissue being the most common sites. We report a case of malignant GCT in a 17-year-old male presented with a paravertebral swelling. Radiological and histopathological findings along with immunohistochemistry were of malignant GCT. We emphasize this case for its uncommon age and site of presentation in addition to invasive nature.

    Axillary Web Syndrome (AWS), also known as lymphatic cording, refers to a condition in which a rope-like soft-tissue density develops in the axilla. It usually appears in the 5 to 8 week period following breast cancer surgery and can lead to shoulder pain and restricted motion. We present a case of AWS in a male squash player with no history of breast cancer or surgery following a period of intense exercise. This case highlights the rare presentation of AWS in a male patient and raises awareness for the health care practitioner who may not suspect this condition in this population. PMID:28065989

    Young males with eating disorders are a neglected study population in eating disorders. The aim of this study was to provide knowledge about the clinical presentation of eating disorders in young males. The data source was the Helping to Outline Paediatric Eating Disorders (HOPE) Project (N ~ 1000), a prospective, ongoing registry comprising consecutive paediatric (<18 years) tertiary eating disorder referrals. Young males with DSM-5 eating disorders (n = 53) were compared with young females with eating disorders (n = 704). There was no significant difference in the prevalence of diagnosis of bulimia nervosa (2 % vs 11 %, p = 0.26) among sexes. Males had comparable duration of illness (9 months; p = 0.28) and a significantly earlier age of onset (M = 12 years; p <0.001). Shape concern (2.39 vs 3.57, p <0.001) and weight concern (1.97 vs 3.09, p <0.001) were lower in males, and body mass index z score (-1.61 vs -1.42, p = 0.29) and medical compromise (odds ratio [OR] = 0.64, 95 % CI: 0.36, 1.12) were comparable. Males had a two-folder higher odds of being diagnosed with unspecified feeding or eating disorders (40 % vs 22 % for females, p = 0.004). Driven exercise to control weight and shape was common and comparable in prevalence among males and females (51 % vs 47 %, p = 0.79) and males were less likely to present with self-induced vomiting (OR = 0.23, 95 % CI: 0.09, 0.59). Boys with eating disorders are an understudied group with similarities and differences in clinical presentation from girls with eating disorders. Parents and physicians are encouraged to consider changes in weight, disturbed vital signs, and driven, frequent exercise for the purposes of controlling weight or shape, as possible signs of eating disorders among male children. Diagnostic classification, assessment instruments, conceptualisation, and treatment methods need to be refined to improve application to young males.

    A 24 year-old male was presented for the diagnosis of an asymptomatic bony expansion in relation to the right maxillary canine and first premolar. The unilocular radiolucent lesion with central foci of calcification had caused divergence of canine and first premolar roots without any resorption. This case report details a diagnosis of two distinct disease processes of different cellular origin namely, focal cemento-ossifying dysplasia and adenomatoid odontogenic tumor in a previously unreported concomitant and contiguous relationship. The diagnosis was determined by a combination of clinical, radiographic, histopathological and surgical evidence. This case highlights two points, first the need to examine all mixed radiolucent-radiopaque lesions with advanced imaging techniques to assess the number and extent of the lesions prior to treatment planning. Second a likely role of periodontal ligament as the tissue source for odontogenic epithelial cells and mesenchymal stem cells required for the development of odontogenic tumors and cemento-osseous dysplasias.

    In males, precocious puberty (PP) is defined as the development of secondary sexual characteristics before age 9 years. PP is usually idiopathic; though, organic abnormalities including tumors are more frequently found in male patients with PP. However, advanced puberty in male also can be an important clinical manifestation in tumors. We report 2 cases of rapidly progressive puberty in males, each associated with a germ-cell tumor. First, an 11-year-old boy presented with mild fever and weight loss for 1 month. Physical examination revealed a pubertal stage of G3P3 with 10-mL testes. Investigations revealed advanced bone age (16 years) with elevated basal luteinizing hormone and testosterone levels. An anterior mediastinal tumor was identified by chest radiography and computed tomography, and elevated α-fetoprotein (AFP) and β-human chorionic gonadotropin (β-hCG) levels were noted. Histopathologic analysis confirmed a yolk-sac tumor. Second, a 12-year-old boy presented with diplopia, polydipsia, and polyuria for 4 months. Physical examination revealed a pubertal stage of G3P3 with 8-mL testes. Bone age was advanced (16 years) and laboratory tests indicated panhypopituitarism with elevated testosterone level. A mixed germ-cell tumor was diagnosed with elevated AFP and β-hCG levels. Of course, these patients also have other symptoms of suspecting tumors, however, rapidly progressive puberty can be the more earlier screening sign of tumors. Therefore, in male patients with accelerated or advanced puberty, malignancy should be considered, with evaluation of tumor markers. In addition, advanced puberty in male should be recognized more widely as a unique sign of neoplasm. PMID:27104181

    Fitz-Hugh-Curtis syndrome is a type of perihepatitis that causes liver capsular infection without infecting the hepatic parenchyma or pelvis. Fitz-Hugh-Curtis syndrome is known to occur commonly in women of childbearing age who do not use oral contraceptives and have sexual partners older than 25 years of age. However, the syndrome has been reported to occur rarely in males. The clinical symptoms are right upper quadrant pain and tenderness, and pleuritic right sided chest pain. The clinical presentation is similar in male and female. We experienced a case of Fitz-Hugh-Curtis syndrome in a 60-year-old man with the chief complaint of right upper quadrant abdominal pain. Despite a previous history of gonorrhea, we have also described our experiences of improved symptoms and recovery with allopathic medicines and have thereby reported the present case with a literature review.

    The emotional victim effect (EVE, i.e., that the emotionality of a victim's demeanor affects perceived credibility) is a robust research finding for female victims of rape but much less explored for other types of victims and crimes. In this article, we investigate the EVE with a male assault complainant. In addition, we vary the presentation mode via which the complainant is shown to the assessors. A sample of law students (N = 81) participated in an experiment where they viewed and assessed credibility of a male complainant who appeared either live or on video. The complainant behaved either in an emotional or a neutral manner. Result showed that the presentation mode but not the EVE affected the assessors' credibility assessments: The complainant was perceived as more truthful when communicating live, as opposed to via video. Practical implications, as well as the generality of the EVE, are discussed.

    Goldberg, Ethan M.; Reynoso, Francis Jeshira; Pradhan, Madhura

    2016-01-01

    Background. Oral-facial-digital syndrome type 1 (OFD1) is a rare condition with X-linked dominant inheritance caused by mutations in the Cxorf5 (OFD1) gene. This gene encodes the OFD1 protein located within centrosomes and basal bodies of primary cilia. Approximately 15–50% of patients with OFD1 progress to end-stage kidney disease following development of polycystic changes within the kidneys. This condition almost always causes intrauterine lethality in males. Description of Case Diagnosis and Treatment. A Caucasian male aged 9 years and 9 months presented with increased urinary frequency, increased thirst, and decreased appetite. Physical examination demonstrated short stature, hearing loss, photophobia, murmur, and hypogonadism. He had no other dysmorphic features. Laboratory results revealed anemia, renal insufficiency, and dilute urine with microscopic hematuria but no proteinuria. Ultrasound showed small kidneys with increased echogenicity but no evidence of cystic changes. A Ciliopathy Panel showed a novel and likely pathogenic deletion, approximately 7.9 kb, in the OFD1 gene encompassing exons 16, 17, and 19 (c.1654+833_2599+423del). Brain MRI did not demonstrate typical OFD1 findings. He is currently on chronic hemodialysis awaiting transplant from a living donor. Conclusions. We present a male patient with OFD1 mutation who lacks the classic OFD1 phenotype who presented with end-stage renal disease without evidence of polycystic changes within the kidneys. PMID:27651963

    Abstract Lesions of anogenital mammary-like glands are rare, and only 44 female cases have been reported. Herein, we describe a particularly rare case of phyllodes tumor of anogenital mammary-like glands in a 41-year-old male presenting anal bleeding. Papillectomy was performed. The excised tumor was circumscribed in shape, and after it was sliced into sections, it was noted that there were leaf-like slits on the surface of cut side. Under the microscope, the tumor was found to be biphasic, with a bland glandular epithelium and low-to-intermediate cellular stroma, which together created the leaf-like slits. Gynecomastoid hyperplasia was evident at the periphery. The epithelium showed immuno-activity for ER, PR(focal), AR, and GCDFP-15. The stromal cells showed positive staining for CD34 and vimentin. The morphology and immunophenotype were similar to benign phyllodes tumors of breast. To the best of our knowledge, this case report represents the first case of phyllodes tumor of anogenital mammary-like glands with gynecomastoid hyperplasia at the periphery in a male patient. To make a diagnosis, we had to differentiate this lesion from hidradenoma papilliferum of skin appendage, phyllodes tumor of ectopic prostatic tissue, and other tumors of anogenital mammary-like glands analogous to the breast tumor (e.g., fibroadenoma phyllodes, periductal stromal sarcoma, and spindle cell carcinoma). While gynecomastia of male breast is usually a result of hormone imbalance, our patient’s tumor did not seem to be related to peripheral hormone status in the anogenital mammary-like glands. Nevertheless, because hormone imbalance has been strongly related to male breast cancer, hormone levels may need to be followed in male patients who have this rare malady.

    Purpura annularis telangiectodes (PAT), also known as Majocchi purpura, is a rare form of pigmented purpuric dermatosis characterized by non-palpable red-brown, occasionally pruritic patches which progress to hyperpigmented halos. Purpura annularis telangiectodes usually presents in female adolescents as benign symmetric lesions with a predilection for the lower extremities. We present an atypical case of unilateral PAT in an elderly male. To our knowledge, our patient at 85-years-old is the oldest PAT and first unilateral purpura annularis telangiectodes case described in the literature.

    Objectives: To describe the pattern of developmental dysplasia of the hip (DDH) in late presenting Jordanian male patients and identify the risk factors and associated findings. Methods: This is a retrospective study of 1145 male patients who attended the Pediatric Orthopedic Clinic for a DDH check up. This study was carried out in the Orthopedic Section, Special Surgery Department, Faculty of Medicine, The University of Jordan, Amman, Jordan between March 2011 and October 2014. Data was collected from medical records, and x-ray measurements were evaluated. Results: Of the 1145 male patients, 43 (3.75%) with 70 involved hips were diagnosed with late- presenting DDH. Being a first-born baby resulted in 41.9% increased risk for DDH. Cesarian delivery was significantly associated with an increased risk of hip dislocation (p=0.004) while normal delivery was significantly associated with acetabular dysplasia (p=0.004). No predictable risk factors were found in 44.2% patients with DDH. Bilateral cases were more common than unilateral cases: (26 [60.5%] versus 17 [39.5%]). Limited abduction was a constant finding in all dislocated hips (p<0.001). Associated conditions, such as club foot and congenital muscular torticollis were not observed. Conclusion: Cesarian section is a significant risk for dislocated hips while normal delivery is significantly associated with acetabular dysplasia. Bilateral DDH is more common than the unilateral. Club foot and torticollis were not observed in this series. PMID:26837397

    Pelizaeus-Merzbacher Disease is an X-linked hypomyelinatiing leukodystrophy. We report mutations in the thyroid hormone transporter gene MCT8 in 11% of 53 families affected by hypomyelinating leukodystrophies of unknown aetiology. The 12 MCT8 mutated patients express initially a Pelizaeus-Merzbacher-Like disease phenotype with a latter unusual improvement of magnetic resonance imaging white matter signal despite absence of clinical progression. This observation underlines the interest of determining both free T3 and free T4 serum concentrations to screen for MCT8 mutations in young patients (<3 y) with a severe Pelizaeus-Merzbacher-Like disease presentation or older severe mentally retarded male patients with "hypomyelinated" regions.

    Communication in nature often occurs within a broad social network, as signals can be perceived by other individuals beyond the primary intended receiver. Because signals often contain information about the signaller's quality, receivers other than the primary intended receiver may use this information in future interactions with the signaller. As a result, individuals who adjust their behavior depending on who is present may experience a selective advantage. The social environment can therefore have an important influence on the evolution of communication signals. We examined how the presence of a female audience influenced male aggressive behavior and post-contest victory displays in the Jamaican field cricket, Gryllus assimilis. We found a significant effect of female audience on aggressive interactions. When there was a female audience present, males were more likely to initiate and escalate fights, but they spent less time producing victory displays, compared to when there was no audience present. Our experiment suggests that the social environment is important in shaping the behavior of individuals during aggressive interactions.

    Rapid progress in fertility preservation strategies has led to the investigation of ways in which fertile gametes could be generated from cryopreserved immature testicular tissue. Childhood cancer patients remain the major group that can benefit from these techniques. Other potential candidates include patients undergoing gonadectomy and patients with Klinefelter's syndrome and cryptorchid testes. This review aims to present an overview of the current state of knowledge in experimental germ cell transplantation, testicular tissue transplantation, and germ cell culture as fertility preservation methods for males. We included English articles published in PubMed as well as personal files with the focus on studies including human or nonhuman material. Germ cell and testicular tissue transplantation demonstrate clinical options to mature germ cells from immature primate testicular tissue. The most promising approach involves autologous grafting of immature testicular tissue, whereas germ cell maturation in vitro provides the best strategies to overcome problems of cancer contamination in cryopreserved testicular tissue. Three-dimensional and organ culture systems offer the possibility to differentiate immature male germ cells up to the stage of elongated spermatids. Further characterization of early germ cell development in humans is needed to modify these systems for clinical use.

    A 17-year-old adolescent boy presented with atypical major depressive episode (MDE) without specific focal neurological signs for 6 months. He had a diagnosis of intra-cranial germinoma, and the atypical MDE symptoms subsided after the operation. However, he had a relapse of atypical MDE 7 months after the first surgery. His mood and binge eating symptoms subsided, but intractable body weight gain only partially improved after treatment. When encountering manifestations of depression with atypical features, especially with binge eating symptoms in male children and adolescents, with early onset age, no family history, and prolonged depressive episodes, clinicians should consider not only mood disorders including bipolar spectrum disorders but also organic brain lesions such as intracranial germinoma.

    Small non-coding RNAs (sncRNAs) are indispensable for proper germ cell development, emphasizing the need for greater elucidation of the mechanisms of germline development and regulation of this process by sncRNAs. We used deep sequencing to characterize three families of small non-coding RNAs (piRNAs, miRNAs, and tRFs) present in Sus scrofa gonads and focused on the small RNA fraction present in both male and female gonads. Although similar numbers of reads were obtained from both types of gonads, the number of unique RNA sequences in the ovaries was several times lower. Of the sequences detected in the testes, 2.6% of piRNAs, 9% of miRNAs, and 10% of tRFs were also present in the ovaries. Notably, the majority of the shared piRNAs mapped to ribosomal RNAs and were derived from clustered loci. In addition, the most abundant miRNAs present in the ovaries and testes are conserved and are involved in many biological processes such as the regulation of homeobox genes, the control of cell proliferation, and carcinogenesis. Unexpectedly, we detected a novel sncRNA type, the tRFs, which are 30-36-nt RNA fragments derived from tRNA molecules, in gonads. Analysis of S. scrofa piRNAs show that testes specific piRNAs are biased for 5' uracil but both testes and ovaries specific piRNAs are not biased for adenine at the 10th nucleotide position. These observations indicate that adult porcine piRNAs are predominantly produced by a primary processing pathway or other mechanisms and secondary piRNAs generated by ping-pong mechanism are absent.

    Cigarette smoking has become an important influence of morbidity and mortality for HIV-positive individuals in the era of highly active antiretroviral therapy. Although smoking is common among military personnel and veterans, the lasting impact of military service on smoking at a later stage of life has not been examined. The current study investigated present and past influences on current smoking among HIV-positive male veterans. Participants were 200 HIV-positive men served by the Veterans Affairs Medical Center. A survey was administered via audio-enhanced computer-assisted self-interview, and additional information was extracted from the computerized patient record system. Logistic regression was performed to test hypotheses concerning the participants' current situations as well as characteristics of their past military service. Having smokers in one's environment, being more depressed, and having used alcohol or drugs were associated with having smoked in the previous 30 days, whereas stronger endorsement of attitudes stating adverse effects of smoking was linked to lower likelihood of smoking. Neither having been in a military conflict nor the length of the military service was significantly related to current smoking. Remote experiences in the military did not have a sustained effect on smoking behavior years later. Implications of this study for the development of smoking cessation programs targeting HIV-positive veterans include the importance of altering attitudes about tobacco, treating underlying depression, addressing social influence, decreasing substance use, and increasing awareness of the heightened vulnerability to a variety of negative consequences of smoking among infected individuals.

Methods: Participants were 200 HIV-positive men served by the Veterans Affairs Medical Center. A survey was administered via audio-enhanced computer-assisted self-interview, and additional information was extracted from the computerized patient record system. Results: Logistic regression was performed to test hypotheses concerning the participants’ current situations as well as characteristics of their past military service. Having smokers in one's environment, being more depressed, and having used alcohol or drugs were associated with having smoked in the previous 30 days, whereas stronger endorsement of attitudes stating adverse effects of smoking was linked to lower likelihood of smoking. Neither having been in a military conflict nor the length of the military service was significantly related to current smoking. Conclusions: Remote experiences in the military did not have a sustained effect on smoking behavior years later. Implications of this study for the development of smoking cessation programs targeting HIV-positive veterans include the importance of altering attitudes about tobacco, treating underlying depression, addressing social influence, decreasing substance use, and increasing awareness of the heightened vulnerability to a variety of negative consequences of smoking among infected individuals.

    Circumcision, a surgical removal of male prepuce has existed throughout human history, and it appears it shall exist until humanity ends. During its entire existence, there have been changing reasons or indications from cultural, traditional, religious and currently medical, and it has vehemently been criticized by some individuals for different reasons and in different countries. Emergency of new diseases particularly Human Immunodeficient virus (HIV) has brought the ancient procedure back on spot light, this has come as a result of recent studies which have demonstrated that it does not only reduces significantly the rate of HIV infection, as well as penile cancer and cervical cancer. This has lead to massive male circumcision campaigns in areas with low prevalence of circumcision. On the other hand the socio-cultural and sexual aspects of male circumcision have been studied but often ignored. This article will therefore increase awareness of male circumcision and the increasing roles with time, recommend up scaling of medical male circumcision and possible safe circumcision training to tradition circumcisers.

    Infertility is a common yet complex problem affecting approximately 10-15% of couples attempting to conceive a baby. Especially, 40-50% of these factors are known as male-related disorders. Unlike female infertility, the cause of which is often easily identified, diagnosing male factors can be difficult. Male infertility is due to low sperm production, abnormal sperm function or blockages of sperm transport. Classical semen analysis in laboratory, which include sperm concentration, motility and morphology gives an approximate evaluation of the functional competence of spermatozoa, but does not always reflect the quality of sperm DNA. The fertilizing potential of sperm depends not only on the functional competence of spermatozoa but also on sperm DNA integrity. The most commonly used techniques to assess sperm DNA integrity are the TUNEL assay, Comet assay, SCSA assay and hallo sperm assay. Recent studies have highlighted the significance of sperm DNA integrity as an important factor which affects functional competence of the sperm. Sperm DNA damage has been closely associated with numerous indicators of reproductive health including fertilization, embryo quality, implantation, spontaneous abortion, congenital malformations. To overcome male infertility, there are variety of surgical and non-surgical urological procedures and medical-pharmacological interventions, and advanced assisted reproductive technologies (ART). Among the surgically retrieved methods, there are TESE, TFNA, PESA and MESA that is used with ICSI. The ART, augmented with ICSI in moderate to serve cases, efficiently treat a variety of male infertility disorders by constituting validated and successfully treatment methods. Also, this technique is employed because the limited numbers and functional capacity of motile sperm that can be obtained. Especially, there are technologies such as IMSI and PICSI that are used to select healthy sperms.

  2. The present and future state of hormonal treatment for male infertility.

    PubMed

    2003-01-01

    Although male factors contribute to over half of all cases of infertility, most infertile men are described as 'idiopathic oligo/asthenozoospermic' rather than diagnosed precisely; hence, specific medical treatment is not possible. One uncommon but treatable cause of male infertility is gonadotrophin deficiency in which gonadotrophin replacement therapy is highly effective at inducing spermatogenesis and fertility. Hormonal therapy is a logical approach for empirical drug therapy given the fundamental role of hormonal regulation in spermatogenesis. However, treatment with GnRH analogues, gonadotrophins, androgens, anti-estrogens, aromatase inhibitors, growth hormone- and prolactin-suppressing drugs is ineffective in unselected infertile men. Prolonged high-dose glucocorticoid therapy for sperm autoimmunity may improve pregnancy rates modestly, but the risks are generally unacceptable compared with IVF or ICSI. For these reasons, modern reproductive technologies, notably ICSI/IVF, have become the de-facto standard empirical treatment of male infertility, despite involving significant though infrequent risks to the fetus and mother. There remains a potential for hormonal methods to improve sperm quality or ultrastructure in subgroups of infertile men more responsive to hormonal manipulation or using novel protein or gene-targeted therapies or biochemical approaches based on post-hormonal receptor mechanisms that stimulate spermatogenesis. How such novel hormonal methods will develop in conjunction with improved ICSI/IVF or cloning technologies, and the potential role of adjunctive hormonal therapy remains to be clarified.

    Girls with congenital adrenal hyperplasia (CAH) diagnosed at birth have some masculine behaviors but rarely convert to male gender. In developing countries, however, diagnosis and treatment (with secondary androgen suppression) are delayed. We aimed to assess effect of delayed treatment of CAH on gender identity. As part of a cross-sectional, case-control study of children with disorders of sex development (DSD), there were 11 patients with CAH. Patients and caregivers answered a questionnaire about gender identity, and behavior was assessed by observing toy play. Patients were examined for Prader score and gender identity. Of 11 CAH patients initially raised as girls, 3 (27%) had converted to male gender at presentation (5, 9, 9years) (Prader 3, 4, 4). Of the remaining 8 patients, one 4-year-old (Prader 2) had a male gender identity score. The remaining girls (2-13years, mean 8.1) (Prader 1-3) had gender identity scores in the female range. One third (4/11) of CAH patients presenting in mid-childhood had male gender identity scores, and ¾ had assumed male gender role. Although social and cultural factors are important in developing countries, this result suggests that delayed treatment may trigger male gender identity, and delayed female genital surgery may be unwise.

    Hashimoto's encephalopathy is an anti-thyroid antibody-positive autoimmune encephalopathy. We herein report the case of a 13-year-old male patient with subacute vertigo, muscle weakness in the extremities and gait disturbance who was diagnosed with Hashimoto's encephalopathy. He showed no severe impairment of consciousness and no seizures, and there were no abnormalities on the brain MRI. However, epileptic spike and wave complexes were observed on an electroencephalogram, and a decline in blood flow was diffusely observed on brain SPECT (single photon emission computed tomography). His thyroid function was normal, but he was positive for anti-thyroid antibodies, such as anti-TPO (thyroid peroxidase) antibodies. He was also positive for serum anti-NAE (NH2-terminal alpha-enolase) antibodies. Systemic corticosteroid therapy and high-dose intravenous immunoglobulin therapy were effective, greatly improving his quality of life.

    Sacroiliac joint (SIJ) can cause low back pain when its joint capsule and ligamentous tissue are damaged. We report our experience in treating three SIJ dysfunction patients presenting with acute low back pain (a 38 year-old male, a 24 year-old male, and a 32 year-old female). SIJ dysfunction was diagnosed using the one-finger test, the modified Newton test, and SIJ injection. In all three patients, lumbar MRI demonstrated slightly degenerated lumbar lesions (lumbar canal stenosis, lumbar disc hernia). Two patients had paresthesia or pain in the leg and all three patients showed iliac muscle tenderness in the groin, which was thought to be a referred symptom because of improvement after SIJ injection. The two male patients returned to work and the problems have not recurred. Although our female patient resumed daily life as a housewife, her condition recurred at intervals of 2-3 months and she required regular SIJ injections. The prevalence of SIJ dysfunction of low back pain is about 10%, so it should be considered as a differential diagnosis when treating low back pain and designing treatment for lumbar spinal disorders.

    Cutaneous angiosarcoma of the head and neck is a rare, highly malignant neoplasm; prognosis is heavily influenced by tumor size, resectability, and stage at initial diagnosis. Most patients present with one to several erythematous to violaceous patches, plaques, or nodules. However, the clinical presentation is highly variable and leads to delayed diagnosis. We report cutaneous angiosarcoma in a 43-year-old man who presented with an 11-month history of progressive solid (non-pitting) edema involving his entire face, scalp, eyelids, and neck without characteristic clinical features of cutaneous angiosarcoma. A skin biopsy had shown non-specific findings consistent with solid facial edema or rosacea. Various etiologies were considered but there was no significant improvement after directed medical therapy. Repeat skin biopsies revealed angiosarcoma involving the dermis and sub-cutis. Computed tomography (CT) of the chest showed multiple lung nodules bilaterally and a lytic lesion in the T6 vertebra consistent with metastases. He was treated with single agent chemotherapy (paclitaxel), and had a partial response that restored his ability to open both eyes spontaneously; However, his edema has recently progressed 7 months after diagnosis. This is a rare example of cutaneous angiosarcoma presenting as progressive solid facial edema, which underscores the diverse range of clinical manifestations associated with this neoplasm.

    Celiac disease is commonly associated with elevated liver enzymes that normalize on a gluten-free diet. Celiac disease is rarely described in patients with primary biliary cholangitis. Dermatitis herpetiformis is the skin manifestation of the celiac disease that is very rarely associated with primary biliary cirrhosis. We present the case of a 62-year-old man who presented with severe chronic pruritus, in whom a diagnosis of primary biliary cholangitis was made initially. However, in the presence of atypical skin lesions, not confirming to chronic cholestasis, an in-depth evaluation including histopathological examination led to the diagnosis of dermatitis herpetiformis associated with gluten sensitivity. Gluten-free diet and medical treatment with dapsone led to beneficial clinical outcomes.

  9. Timing of presentation of an audience: aggressive priming and audience effects in male displays of Siamese fighting fish (Betta splendens).

    Studies of animal communication often underestimate the presence of individuals other than the signaller-receiver dyad. Signalling interactions often occur in the presence of non-participating individuals (audiences); the effect of these individuals upon the dynamics of interactions has been called the audience effect. Recent studies of fighting fish Betta splendens have shown that the presence of a male audience can increase aggression during interactions. However, in many of these studies males were allowed to see the audience prior to the interaction, thus such pre-exposure may have facilitated aggressive behaviour (aggressive priming). Here we present results of two experiments designed to examine the relative importance of priming and audience effects on the dynamics of aggressive interactions. Males that were pre-exposed showed higher levels of aggression during subsequent interactions regardless of the presence or absence of an audience. When only one of the interactants had been pre-exposed to the audience, the non-exposed male showed similar increases in aggressive behaviour, i.e. matching the level of aggression showed by his opponent. Taken together these results suggest that aggressive priming may have resulted in an over-estimation of the audience effect in previous studies. The results still highlight the importance of social environment in determining the dynamics and outcomes of aggressive contests.

    The current research examined contested meanings of nudity by comparing images of nude men and women that appeared in Viva, a 1970s women's magazine founded with the intention of foregrounding male nudity, to corresponding issues of Playboy. A major difference was obtained between male models and Playboy Playmates regarding direction of gaze and nudity. Although gaze aversion is often interpreted as a sign of submission and direct gaze is seen as a dominance cue, men in Viva displayed a high level of gaze aversion and women in Playboy often gazed directly at the camera, especially when their pubic area was exposed. Additional content analysis examined the personality characteristics attributed to male models in Viva and Playmates in Playboy in their biographical sketches. In Viva, men were presented as possessing "bad boy" traits that may have been intended to compensate for the loss of power associated with male nudity. Playmates could be viewed as being naughty (by virtue of posing nude) and nice in the characterization of their personalities.

    Adamantinomas are rare, low-grade malignant intra-osseous tumors composed of epithelial and mesenchymal elements, which show a marked predilection for the tibia and fibula of young adult male patients. Although cases of adamantinoma located to the axial skeleton have been reported either as recurrent or metastatic disease, only two cases of primary adamantinoma located to the thoracic wall have been previously described. In this study we present the clinical, radiological and histopathological features of a 24-year-old male with a slow growing, solid-cystic, painful mass, located to the right 11th rib, which was morphological and immunohistochemically diagnosed as a primary classic adamantinoma. Radiological studies showed a multiloculated lesion with a solid component. The patient underwent a whole surgical resection of the lesion. Histologically, multiple foci of epithelial cells with basaloid and squamous components were found intermixed within a fibrous stromal tissue. Immunohistochemical analysis demonstrated expression of cytokeratins, EMA, vimentin and other epithelial markers. Primary affection of the rib is an unusual feature of classic adamantinomas.

    Pulmonary alveolar microlithiasis (PAM) is a rare chronic disease with paucity of symptoms in contrast to the imaging findings. We present a case of a 24-year-old Malay man having an incidental abnormal pre-employment chest radiograph of dense micronodular opacities giving the classical "sandstorm" appearance. High-resolution computed tomography of the lungs showed microcalcifications with subpleural cystic changes. Open lung biopsy showed calcospherites within the alveolar spaces. The radiological and histopathological findings were characteristic of PAM.

    This report describes a new fatal syndrome observed in adolescent males at the initial presentation of diabetes mellitus. The features include hyperglycemic hyperosmolar coma complicated by a malignant hyperthermia-like picture with fever, rhabdomyolysis, and severe cardiovascular instability. Case series. Pediatric intensive care units of 3 tertiary care facilities in the United States. Six adolescent males, 5/6 obese with acanthosis nigricans, 4/6 black. Four of 6 patients died. Four of 6 patients did not have significant ketosis. Six of 6 patients had increased temperature after the administration of insulin. The underlying etiology of this syndrome remains unclear. Possibilities include an underlying metabolic disorder such as a fatty acid oxidation defect, an unrecognized infection, exposure to an unknown toxin, or a genetic predisposition to malignant hyperthermia. Evaluation for all these possibilities and empiric treatment with dantrolene should be considered for this type of patient until this syndrome is better characterized.

  15. Tactics for male reproductive success in plants: contrasting insights of sex allocation theory and pollen presentation theory.

    PubMed

    Thomson, James D

    2006-08-01

    The basic tenet of sex allocation theory is that an organism's reproductive success, through either male or female function, can be represented as a sex-specific, monotonic, increasing function of the organism's investment of resources in that function. The shapes of these curves determine what patterns of resource allocation can be evolutionarily stable. Although SA theory has stimulated creative thinking about plant sexual tactics, quantifying the shapes of male and female gain curves has proven so difficult that other approaches must be considered. I contrast sex allocation theory to a different, emerging viewpoint, pollen presentation theory (PPT), which attempts to address variation in reproductive success by measuring and modeling the quantitative fates of pollen grains. Models suggest that RS through male function depends heavily on the packaging and gradual dispensing of pollen to pollinators, even with the amount of investment held constant. Many plants do deploy pollen gradually, through morphological and "behavioral" mechanisms that range from obvious to subtle. They may thereby influence many aspects of the evolution of sexual modes in plants, including transitions between dioecy and cosexuality. After reviewing the main implications of the models, I discuss recent work aimed at testing some key assumptions and predictions by functional and comparative studies in the genus Penstemon. Species of Penstemon conform to PPT predictions that bee-adapted flowers will restrict per-visit pollen availability more than hummingbird-adapted flowers.

    Background The understanding of vertical ground reaction force (VGRF) during walking and half-squatting is necessary and commonly utilised during the rehabilitation period. The purpose of this study was to establish measurement reproducibility of VGRF that reports the minimal detectable changes (MDC) during walking and half-squatting activity among healthy male adults. Methods 14 male adults of average age, 24.88 (5.24) years old, were enlisted in this study. The VGRF was assessed using the force plates which were embedded into a customised walking platform. Participants were required to carry out three trials of gait and half-squat. Each participant completed the two measurements within a day, approximately four hours apart. Results Measurements of VGRF between sessions presented an excellent VGRF data for walking (ICC Left = 0.88, ICC Right = 0.89). High reliability of VGRF was also noted during the half-squat activity (ICC Left = 0.95, ICC Right = 0.90). The standard errors of measurement (SEM) of VGRF during the walking and half-squat activity are less than 8.35 Nm/kg and 4.67 Nm/kg for the gait and half-squat task respectively. Conclusion The equipment set-up and measurement procedure used to quantify VGRF during walking and half-squatting among healthy males displayed excellent reliability. Researcher should consider using this method to measure the VGRF during functional performance assessment. PMID:27547111

    Introduction: Sexual dysfunction can occur due to biological problems, relationship problems, lack of proper sexual knowledge or a combination of these. India is often known as the land of Kamasutra. But as far as sexuality research is concerned, there is a paucity of relevant data from India. In view of this, we conducted a study to assess the psychosocial profile of males presenting with sexual dysfunction to psychiatry out-patient department of a tertiary medical hospital. Materials and Methods: Hundred consecutive male patients presenting with sexual dysfunction were screened using Arizona Sexual Experiences Scale for clinical sexual dysfunction and after obtaining their informed consent were included in this study. They were assessed using a semi-structured proforma, Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision criteria, Mini-International Neuropsychiatric Interview, and Dyadic Adjustment Scale. Results: Majority of our respondents were in the 18–30 years age group and were married. The main source of sex knowledge for 69% of them was peer group. Age of onset of masturbation was 11–13 years for 43% of them. Premature ejaculation was the most common sexual dysfunction seen in the respondents. Marital discord was seen in significantly lesser number of respondents (32.35%) as also major depressive disorder that was seen in only 16%. Discussion: Premature ejaculation was the most common sexual dysfunction in our sample. Despite the sexual dysfunction, marital discord and depression were seen less commonly in our respondents.

    This male patient presented with a scrotal abscess and urinary obstruction. The patient's history included a perineal abscess and the development of urethrocutaneous fistulae (watering-can perineum). He underwent multiple debridement procedures without resolution. During the fifth debridement for Fournier's gangrene, a biopsy revealed invasive squamous cell carcinoma. The patient was bedridden because of the large mass, a wide en bloc resection with lymphadenectomy and reconstruction was performed revealing a large (22 cm) squamous cell carcinoma originating from the urethra. He also received palliative chemoradiotherapy and hip hemiarthroplasty. Unfortunately, he succumbed to the disease. Given the recognized relationship between inflammation and the development of cancer, it is important to entertain a differential diagnosis of cancer, especially with erosive infections. This case report highlights the all too common late presentation of urethral cancer. Interestingly, despite correction of the bedridden state with palliative surgery, the patient did not perceive an improvement in quality of life based on the FACT-G questionnaire.

    A zinc (Zn)-binding protein that is present specifically in the livers of male adult rats was detected by HPLC with in-line detection by mass spectrometry (ICP MS). The Zn-binding protein was purified on Sephadex G-75 and G3000SW HPLC columns. and was identified as carbonic anhydrase III (CAIII) based on the amino acid sequence of a peptide obtained on lysyl endopeptidase digestion. CAIII is expressed as one of the major Zn-binding proteins in the livers of male rats in an age-dependent manner, a comparable amount of Zn to that of copper, Zn-superoxide dismutase (Cu,Zn-SOD) being bound to CAIII at 8 weeks of age. Castration at 4 or 8 weeks of age was shown to reduce Zn bound to CAIII to 47.5% of the sham-operated control level, suggesting that the sex-dependent expression of CAIII is partly regulated by a sex hormone, androgen. The concentration of CAIII in the livers of Long-Evans rats with a cinnamon-like coat color (LEC rats), an animal model of Wilson disease, was also estimated as Zn bound to CAIII and shown to be lower than that in Wistar rats before the onset of hepatitis. The concentration of CAIII was decreased specifically by repeated injections of cupric ions without the Cu,Zn-SOD concentration being affected.

    Background: Vertical jump is an index representing leg/kick power. The explosive movement of the kick is the key to scoring in martial arts competitions. It is important to determine factors that influence the vertical jump to help athletes improve their leg power. The objective of the present study is to identify anthropometric factors that influence vertical jump height for male and female martial arts athletes. Methods: Twenty-nine male and 25 female athletes participated in this study. Participants were Malaysian undergraduate students whose ages ranged from 18 to 24 years old. Their heights were measured using a stadiometer. The subjects were weighted using digital scale. Body mass index was calculated by kg/m2. Waist–hip ratio was measured from the ratio of waist to hip circumferences. Body fat % was obtained from the sum of four skinfold thickness using Harpenden callipers. The highest vertical jump from a stationary standing position was recorded. The maximum grip was recorded using a dynamometer. For standing back strength, the maximum pull upwards using a handle bar was recorded. Multiple linear regression was used to obtain the relationship between vertical jump height and explanatory variables with gender effect. Results: Body fat % has a significant negative relationship with vertical jump height (P < 0.001). The effect of gender is significant (P < 0.001): on average, males jumped 26% higher than females did. Conclusion: Vertical jump height of martial arts athletes can be predicted by body fat %. The vertical jump for male is higher than for their female counterparts. Reducing body fat by proper dietary planning will help to improve leg power. PMID:23785254

Body fat % has a significant negative relationship with vertical jump height (P < 0.001). The effect of gender is significant (P < 0.001): on average, males jumped 26% higher than females did. Vertical jump height of martial arts athletes can be predicted by body fat %. The vertical jump for male is higher than for their female counterparts. Reducing body fat by proper dietary planning will help to improve leg power.

    Pituitary apoplexy is an acute clinical event usually caused by hemorrhage or infarction in a pituitary adenoma. We report the unusual case of hemorrhagic pituitary apoplexy in an 18 year-old male with previously undiagnosed type 2 diabetes mellitus who presented with unexplained hyperglycemia (glucose 49.2 mmol/l [887 mg/dl]) and obtundation and in whom an initial diagnosis of non-ketotic hyperglycemic coma (NKHC) was made. MRI revealed a heterogeneous mass arising from an expanded sella turcica into the suprasellar cistern. Despite well-controlled glucose levels on continuous insulin infusion, dexamethasone, and initiation of bromoergocriptine (parlodel) therapy, the patient's vision and pupillary responses deteriorated acutely. Following emergency transphenoidal surgery, the patient's vision and mental status improved. Data confirmed preoperative panhypopituitarism; serum prolactin was 396 ng/ml (microg/l). Immunostudies demonstrated tumoral labeling for prolactin, but not for ACTH, GH, TSH, LH, FSH, or P53.

    Introduction To describe the role of laparoscopy for removal of entrapped vaginal metallic dilator (20 cm in length and 3.5 cm in diameter) in a case of male-to-female transsexual. Presentation of the case The patient was a 24-year old male-to-female transsexual, presented with entrapment and upward migration of the vaginal metallic dilator 1 week before admission. She underwent gender reassignment surgery with sigmoid vaginoplasty 8 month before admission. After 3-port transperitoneal laparoscopic abdominopelvic exploration, through an incision over the sigmoid vagina the dilator was extracted. The sigmoid vagina was repaired with free-hand intracorporeal laparoscopic suturing and knot-tying techniques in two layers and the dilator was removed by extending the site of umbilical port. The operative time was 70 min. Discussion Up to 60% of rectosigmoidal or vaginal foreign bodies can be extracted transanally or transvaginally with adequate sedation. When surgical exploration is indicated, a longitudinal laparatomy is performed to extract the foreign body. To reduce the associated morbidity of an open procedure in our patient, we performed a laparoscopic approach for complete abdominal exploration for possible presence of intestinal or sigmoidal injuries together with removal of this large metalic dilator. Conclusion Laparoscopic approaches in cases of neovaginal foreign body are useful when the endovaginal approaches have failed, especially in transsexual patients, to prevent another major open surgery.

    Firearm violence is a leading cause of death among youth. The objectives of this study were (1) determine firearm possession rates and associated correlates among youth seeking care for assault in an emergency department (ED); (2) understand differences in risk factors for youth with firearm possession; and (3) identify firearm possession characteristics in this population: type, reason for possession, and source of firearms. Youth (14 to 24 years old) presenting to a Level 1 ED with assault were administered a computerized screening survey. Validated instruments were administered, measuring demographics, firearm rates and characteristics, attitudes toward aggression, substance use, and previous violence history. Among 689 assault-injured youth, 23% reported firearm possession in the past 6 months. Only 17% of those reporting firearm possession obtained the gun from a legal source; 22% reported ownership of highly lethal automatic/semiautomatic weapons and 37.1% reported having a firearm for protection. Logistic regression analysis identified significant correlates of firearm possession, including male gender, higher socioeconomic status, illicit drug use, recent serious fight, and retaliatory attitudes. ED assault-injured youth had high rates of firearm possession (23.1%), most of which were not obtained from legal sources. Youth with firearm possession were more likely to have been in a recent serious fight, and to endorse aggressive attitudes that increase their risk for retaliatory violence. Future prevention efforts should focus on minimizing illegal firearm access among high-risk youth, nonviolent alternatives to retaliatory violence, and substance use prevention.

    We report two cases of eruptive tumors of the follicular infundibulum (TFI) with an unusual clinical presentation which has not been described previously in literature. In both cases, the appearance was strikingly similar, consisting of multiple asymptomatic hypopigmented macules on the buttocks of two Black African males, aged 38 and 55 years old. In both cases, the eruption had evolved over several months. The individual lesions were of similar size, approximately 1 cm, with irregular and ill-defined borders. Histopathological examination revealed a superficial and horizontal plate-like proliferation of keratinocytes emanating from the epidermis with multiple slender attachments. Pale keratinocytes were present within the epithelial plates. A Fontana stain showed a loss of melanin pigment from the epithelial plates. Orcein (elastic) stain highlighted an increase of the number of the elastic fibers surrounding the tumor. On the basis of these findings, a diagnosis of eruptive TFI was established for both cases. Among the various presentations of TFI, only the eruptive variant appears to be clinically distinctive, with asymptomatic hypopigmented macules usually located on the face, neck and upper trunk. Eruptive TFI should also be added to the clinical differential diagnosis of multiple hypopigmented macules on the buttocks of Black patients. Copyright © 2012 John Wiley & Sons A/S.

    A 24 year old woman presented with a sudden excruciating headache mimicking an acute vascular event. She had undergone a lung transplantation because of cystic fibrosis and was receiving maintenance treatment with tacrolimus and prednisone. Ancillary investigation excluded vascular causes. Magnetic resonance imaging demonstrated hyperintense lesions in the infratentorial and parieto-occipital regions consistent with posterior leucencephalopathy syndrome. Both her clinical condition improved and the lesions disappeared completely after withdrawal of tacrolimus, suggesting that her condition could be explained by a tacrolimus encephalopathy.

    Dioecy distributed in 157 flowering plant families and 959 flowering plant genera. Morphological and physiological differences between male and female plants have been studied extensively, but studies of sex-specific genetic diversity are relatively scarce in dioecious plants. In this study, 20 SSR loci were employed to examine the genetic variance of male subpopulations and female subpopulations in Salix viminalis. The results showed that all of the markers were polymorphic (Na = 14.15, He = 0.7566) and workable to reveal the genetic diversity of S. viminalis. No statistically significant difference was detected between male and female subpopulations, but the average genetic diversity of male subpopulations (Na = 7.12, He = 0.7071) and female subpopulations (Na = 7.31, He = 0.7226) were high. Under unfavorable environments (West Liao basin), the genetic diversity between male and female subpopulations was still not significantly different, but the genetic diversity of sexual subpopulations were lower. The differentiation of the ten subpopulations in S. viminalis was moderate (FST = 0.0858), which was conformed by AMOVA that most of genetic variance (94%) existed within subpopulations. Pairwise FST indicated no differentiation between sexual subpopulations, which was accompanied by high long-term migrate between them (M = 0.73~1.26). However, little recent migration was found between sexual subpopulations. Therefore, artificial crossing or/and transplantation by cutting propagation should be carried out so as to increase the migration during the process of ex situ conservation. PMID:27047511

    Secular trends in the facial skull over three Central European samples spanning more than 13 centuries were examined. Data were 43 conventional cephalometric landmark points for samples dating from 680 to 830 AD (29 male Avars), from the mid-19th century (49 adult Hapsburg Monarchy males), and from the 20th century (54 living Austrian young adult males). Analyses by standard methods of geometric morphometrics demonstrated shape differences by data and by size, with a strong interaction of these with sample, in that group mean differences were different for small and large individuals (allometry is different from period to period). The oldest sample, from the Migration Period, exhibited allometric features that may possibly be Turkic. There are implications for the orthodontist interested in growth trends or growth predictions in ethnically mixed patient samples.

    Meiotic studies were undertaken in a 24-year-old male patient with short stature, chondrodysplasia punctata, ichthyosis, steroid sulfatase deficiency, and mild mental retardation with an inherited cytologically visible deletion of distal Xp. Molecular investigations showed that the pseudoautosomal region as well as the steroid sulfatase gene were deleted, but telomeric sequences were present at the pter on the deleted X chromosome. A complete failure of sex-chromosome pairing was observed in the primary spermatocytes of the patient. Telomeric approaches between the sex chromosomes were made at zygotene in some cells, but XY synaptonemal complex was formed. The sex chromosomes were present as univalents at metaphase I, and germ-cell development was arrested between metaphase I and metaphase II in the vast majority of cells, consistent with the azoospermia observed in the patient. The failure of XY pairing in this individual indicates that the pseudoautosomal sequences play an important role in initiating XY pairing and formation of synaptonemal complex at meiosis. 36 refs., 6 figs.

    Dental caries in infants and young children is prevalent worldwide; its magnitude and associated factors vary between communities because of cultural and social economic differences. No such information was available for pre-school children in Mbeya city. To determine dental caries status and associated factors in 2 to 4-year-old children in Mbeya city. A cross sectional study was conducted among 525 children aged 2-4 years and their parents/caregivers. Caries was assessed using caries assessment spectrum and treatment index, oral hygiene by visual inspection for visible plaque on index teeth, and dietary and oral hygiene habits by a questionnaire. Kappa statistics was used to test reliability of study instruments, χ(2)-test and logistic regression was employed for studying associations. Caries free children for dmft1, dmft2 and dmft3 were 79.8%, 83.8% and 94.7% and caries experience was 0.49 (1.23), 0.4 (1.14) and 0.10 (0.53) respectively. Older age [(OR =2.722 (1.617-4.582) p=< 0.001)]; and frequent consumption of factory made sugary foods/snacks at age 1-2 years [(OR=3.061 (1.188-7.887) p=0.021] were associated with caries. Prolonged breastfeeding for more than 1 year and breastfeeding at night had no association with dental caries. The prevalence of dental caries was very low. Older age and frequent consumption of factory made sugary foods at age 1-2 years were associated with higher odds of developing dental caries. Prolonged breasfeeding and breastfeeding at night had no association with dental caries. Prevention of dental caries should be instituted as soon as primary teeth start erupting, especially through discouraging consumption of factory made sugary foods/snacks.

    Once mated, the optimal strategy for females of the monandrous butterfly, Pararge aegeria, is to avoid male contact and devote as much time as possible to ovipositing, as there is little advantage for females to engage in multiple matings. In other butterfly species the presence of males during egg laying has been shown to affect aspects of oviposition behavior and it has been suggested that repeated interference from males has the potential to reduce reproductive output. The aim of this study was to assess the effects of male presence during oviposition on reproductive output and behavior of a population of P. aegeria obtained from Madeira Island, Portugal, and maintained in the laboratory. Two experiments were performed where females were housed individually in small cages. Experiment 1 examined how social factors influenced the egg laying behavior of females. To do this the presence or absence of males was manipulated and egg size and number was measured over the first 14 days of oviposition. It was observed that when males were present during oviposition females made a trade-off between egg size and number. Experiment 2 examined how social factors affected oviposition site choice. Again, male presence/absence was manipulated, but in this experiment where the female laid her egg in relation to host quality was scored, and the size of the egg laid was measured. In the absence of males females selectively positioned their larger eggs on good quality host plants. However, selective oviposition was no longer observed when females were in the presence of males. We suggest that P. aegeria females from the Madeira Island population are adapted for a flexible oviposition strategy, governed by external cues, allowing a trade-off between egg size and number when the time available for egg laying is limiting.

    Lyme disease is the most common vector-borne infection in the United States with 300,000 estimated cases per year. The purpose of this study was to compare the presenting clinical features and long-term outcome of males versus females with culture-confirmed early Lyme disease. 174 males and 109 females with culture-confirmed erythema migrans were entered into a prospective study with follow-up visits scheduled at six months, 12 months and annually thereafter for up to 20 years. Males and females with early Lyme disease had a similar likelihood of having multiple erythema migrans skin lesions and had a similar number of additional subjective symptoms, such as fatigue, at study entry. Among the 71 males and 57 females able to be followed up for 11-20 years, there were no significant differences in baseline symptoms, rate of seroreactivity to Borrelia burgdorferi, or in frequency of post-treatment symptoms. Females, however, were significantly more likely than males to return for follow-up visits (P = 0.0003). Males and females with culture-confirmed early Lyme disease had similar clinical features, rates of seropositivity, and long-term outcomes. Copyright © 2016 Elsevier Inc. All rights reserved.

    Introduction: Leishmaniasis is a neglected tropical disease caused by vector-borne protozoa of the genus Leishmania. Cutaneous and mucocutaneous forms result in disfiguration or mutilation, whilst visceral leishmaniasis (VL) affects multiple organs and is fatal if untreated. Notably, Leishmania are capable of establishing a chronic infection, which may reactivate years after initial infection when the host becomes immune-suppressed. Case Presentation: A 24-year-old human immunodeficiency virus (HIV)-positive male presented for excision of anal condylomas. At the time of his current condyloma excision, the patient had no additional symptoms or cutaneous findings, but was noted to have been only intermittently compliant with his antiretroviral therapy. Microscopic examination of the haematoxylin and eosin-stained anal condyloma tissue revealed koilocytic change, ulceration and brisk histiocytic inflammation containing numerous small intracellular bodies suggestive of Leishmania amastigotes. A bone marrow biopsy was performed and demonstrated similar intracellular forms. Anal condyloma tissue and bone marrow aspirate were sent to the Centers for Disease Control and Prevention's Parasitic Diseases Branch for confirmation of Leishmania and speciation. Specific immunohistochemical staining for Leishmania in the tissue section was positive and the species was confirmed as Leishmania donovani by PCR. Subsequently, the patient resumed highly active antiretroviral therapy and received anti-Leishmania therapy. Conclusion: Whilst the presentation of VL in HIV-positive patients is often similar to those without HIV, here we describe an unusual initial presentation of leishmaniasis in an HIV-positive patient where the parasite was found in an anal condyloma. VL is a critical diagnosis that should be considered and pursued when leishmaniasis is encountered in seemingly illogical clinical settings. PMID:28348746

    Kikuchi-Fujimoto disease is so named because Kikuchi and Fujimoto were the first scientists to describe it in Japan in 1972. Although the disease has been reported from all over the world and more so from Asia, it is rare. To date only eight cases have been reported from Nepal. Cervical lymphadenopathy, fever and raised Erythrocyte Sedimentation Rate are usual presenting features of this disease. We describe a case which presented with thrombocytopenia and axillary lymphadenopathy in addition to the usual features. Out of the total eight cases that have been reported from Nepal so far, no patients had thrombocytopenia and only one patient had axillary lymphadenopathy. A 24-year-old Nepali female presented with a 3-week history of low-grade fever, headache, and painful, discrete, unilateral left-sided cervical and axillary lymphadenopathy. Among the multitude of tests that were carried out, Erythrocyte Sedimentation Rate was raised and there was thrombocytopenia while other tests were normal. Painful lymphadenopathy pointed to bacterial lymphadenitis while chronic low-grade fever suggested tuberculosis. A cervical lymph node was excised for histopathological examination to reach an accurate diagnosis. On the basis of pathognomonic features viz., paracortical foci composed of various types of histiocytes including crescentic type in the background of abundant apoptotic karyorrhectic debris, a diagnosis of Kikuchi-Fujimoto disease was made. On follow-up evaluation after 6 weeks, the patient had no systemic symptoms, enlarged lymph nodes had regressed in size significantly, and Erythrocyte Sedimentation Rate and platelet count had become normal. Kikuchi-Fujimoto disease should be kept in the differential diagnosis of lymphadenopathy in young patients, female or male even in tuberculosis-endemic countries and even in patients who have unusual features; for example thrombocytopenia and involvement of axillary lymph nodes in addition to cervical lymph nodes as in this

    Despite men being less prone to develop autoimmune diseases, male sex has been associated with a more severe disease course in several systemic autoimmune diseases. In the present study, we aimed to investigate differences in the clinical presentation of primary Sjögren's syndrome (pSS) between the sexes and establish whether male sex is associated with a more severe form of long-term pSS. Our study population included 967 patients with pSS (899 females and 68 males) from Scandinavian clinical centers. The mean follow-up time (years) was 8.8 ± 7.6 for women and 8.5 ± 6.2 for men (ns). Clinical data including serological and hematological parameters and glandular and extraglandular manifestations were compared between men and women. Male patient serology was characterized by more frequent positivity for anti-Ro/SSA and anti-La/SSB (p = 0.02), and ANA (p = 0.02). Further, men with pSS were more frequently diagnosed with interstitial lung disease (p = 0.008), lymphadenopathy (p = 0.04) and lymphoma (p = 0.007). Conversely, concomitant hypothyroidism was more common among female patients (p = 0.009). We observe enhanced serological responses and higher frequencies of lymphoma-related extraglandular manifestations in men with pSS. Notably, lymphoma itself was also significantly more common in men. These observations may reflect an aggravated immune activation and a more severe pathophysiological state in male patients with pSS and indicate a personalized managing of the disease due to the influence of the sex of patients with pSS.

    The first case of man who presented to psychiatry emergency room for evaluation of abnormal behavior because of urinary stones was reported. Careful evaluation of patient led to a diagnosis of 37 urinary bladder stones in an Egyptian man with obstructive uropathy and metabolic defects in the form of hyperoxaluria and hypocitraturia. Knowledge of the differential diagnosis of metabolic defects can lead to successful outcome in preventing reformation of urinary tract stones after surgery. A 61-year-old Egyptian man presented to psychiatry emergency room because he was found lying on floor in bathroom to urinate by his wife who thought her husband needed psychiatric evaluation. Patient gave history of frequent urination and dysuria on and off for 3 years. In the last 3 months before his presentation to emergency room, he got into a habit of lying down on his left side when he went to bathroom to urinate because it was easier for him to pass urine. Renal consultation requested because of presence of red blood cells in urinalysis. Computed tomography of the abdomen and pelvis showed bilateral hydronephrosis and multiple bladder stones. Twenty-four-hour urine collection showed low urinary citrate and high oxalate. Patient underwent open vesicolithotomy and removal of 36 stones. Stone analysis showed 75% uric acid and 25% calcium oxalate. Patient did very well after surgery, and 1 month later, he underwent transuretheral resection of prostate without any complications. Now patient has no difficulty passing urine and he has no recent attack of urinary tract infection. Knowledge of the differential diagnosis of metabolic defects in men with urinary bladder stones would hopefully provide clinicians with the proper diagnostic tools to more specifically treat such patients with improved success in preventing reformation of urinary tract stones after surgery.

    This research extends prior epidemiological estimates for the United States and re-examines a previously described male excess in alcohol drinking. Its aim was to estimate fine-grained age-specific incidence of becoming a drinker among 12- to 24-year-old U.S. males and females, and to compare incidence estimates with prevalence proportions. The study population is 12- to 24-year-old noninstitutionalized U.S. civilian residents. Estimates are from 12 successive U.S. National Surveys on Drug Use and Health (NSDUH), with nationally representative samples drawn each year from 2002 to 2013 and assessed via computer-assisted self-interviews (n ~ 390,000). Analysis-weighted incidence and prevalence estimates are generated using the NSDUH Restricted Data Analysis System for 6 year-pairs. Meta-analysis-derived summary estimates are provided, treating each year-pair as a replication. In this 21st century evidence, there no longer is male excess of incidence with respect to underage drinking. Indeed, in mid-adolescence, there is a clear female excess for the risk of becoming an underage drinker. Meta-analytic summaries disclosed no other male-female differences in incidence. Nevertheless, a male excess in the prevalence of recently active drinking can be seen after the age of 19 years. This new evidence from the United States shows that the so-called "gender gap" in risk of becoming a drinker has narrowed to the point of there being no gap at all. Indeed, in mid-adolescence, risk of starting to drink is greater for females than for males. Copyright © 2016 by the Research Society on Alcoholism.

    Pulmonary Langerhans cell histiocytosis is an uncommon diffuse cystic lung disease in adults. In rare cases, it can involve extrapulmonary organs and lead to endocrine abnormalities such as central diabetes insipidus. A 42-year-old man presented with polyphagia and polydipsia, as well as a dry cough and dyspnea on exertion. Magnetic resonance imaging of the hypothalamic-pituitary system failed to show the posterior pituitary, which is a typical finding in patients with central diabetes insipidus. This condition was confirmed by a water deprivation test, and the patient was also found to have type 2 diabetes mellitus. Computed tomographic scanning of the lungs revealed multiple, irregularly shaped cystic lesions and small nodules bilaterally, with sparing of the costophrenic angles. Lung biopsy through video-assisted thoracoscopic surgery revealed pulmonary Langerhans cell histiocytosis. On a follow-up visit, only 1 year after the patient had quit smoking, clinical and radiological improvement was significant. Here, we report an uncommon case of pulmonary Langerhans cell histiocytosis that simultaneously presented with diabetes insipidus and diabetes mellitus.

    This study evaluated the influence of the alcohol present in a formulation of the antiophidic phytotherapic tincture, Específico-Pessôa, on rat blood biochemical and hematological parameters, and on organ histology. Three groups of rats were treated orally for 10, 15, or 30 days; one group received the tincture, the other received alcohol alone, and the third was a control group. The results of this study indicated that cholesterol levels were significantly increased after 10 days in the alcohol and tincture groups, although these decreased after 30 days in the tincture group. Triglyceride levels were significantly reduced after 15 days in the tincture group and after 30 days in the alcohol and tincture groups. A higher creatinine level was observed in the alcohol and tincture groups after 15 and 30 days. The uric acid levels in these groups were reduced at 10 and 30 days, although this metabolite was elevated at 15 days in the alcohol group. Hydropic multifocal degeneration with lymphohistiocytic infiltration and some polymorphonuclear cells was observed in the livers of rats treated with either the tincture or alcohol. These data demonstrate the importance of considering the potential actions of the alcohol present in pharmaceutical formulations. PMID:26823673

    BACKGROUND AND OBJECTIVES: Firearm violence is a leading cause of death among youth. The objectives of this study were (1) determine firearm possession rates and associated correlates among youth seeking care for assault in an emergency department (ED); (2) understand differences in risk factors for youth with firearm possession; and (3) identify firearm possession characteristics in this population: type, reason for possession, and source of firearms. METHODS: Youth (14 to 24 years old) presenting to a Level 1 ED with assault were administered a computerized screening survey. Validated instruments were administered, measuring demographics, firearm rates and characteristics, attitudes toward aggression, substance use, and previous violence history. RESULTS: Among 689 assault-injured youth, 23% reported firearm possession in the past 6 months. Only 17% of those reporting firearm possession obtained the gun from a legal source; 22% reported ownership of highly lethal automatic/semiautomatic weapons and 37.1% reported having a firearm for protection. Logistic regression analysis identified significant correlates of firearm possession, including male gender, higher socioeconomic status, illicit drug use, recent serious fight, and retaliatory attitudes. CONCLUSIONS: ED assault-injured youth had high rates of firearm possession (23.1%), most of which were not obtained from legal sources. Youth with firearm possession were more likely to have been in a recent serious fight, and to endorse aggressive attitudes that increase their risk for retaliatory violence. Future prevention efforts should focus on minimizing illegal firearm access among high-risk youth, nonviolent alternatives to retaliatory violence, and substance use prevention. PMID:23837181

    Using signal detection methods, possible effects of emotion type (happy, angry), gender of the stimulus face, and gender of the participant on the detection and response bias of emotion in briefly presented faces were investigated. Fifty-seven participants (28 men, 29 women) viewed 90 briefly presented faces (30 happy, 30 angry, and 30 neutral, each with 15 male and 15 female faces) answering yes if the face was perceived as emotional and no if it was not perceived as emotional. Sensitivity [d', z(hit rate) minus z(false alarm rate)] and response bias (β, likelihood ratio of "signal plus noise" vs. "noise") were measured for each face combination for each presentation time (6.25, 12.50, 18.75, 25.00, 31.25 ms). The d' values were higher for happy than for angry faces and higher for angry-male than for angry-female faces, and there were no effects of gender-of-participant. Results also suggest a greater tendency for participants to judge happy-female faces as emotional, as shown by lower β values for these faces as compared to the other emotion-gender combinations. This happy-female response bias suggests, at least, a partial explanation to happy-superiority effects in studies where performance is only measured as percent correct responses, and, in general, that women are expected to be happy. © 2011 The Author.

    Limited data exist regarding the effect of the growth process on anterior cruciate ligament (ACL) injury risk in male versus female children. The proportion of ACL injuries/sports injuries presenting to clinic will vary by age, sex, and body mass index (BMI). Cross-sectional epidemiologic study. Level 3. The study group consisted of a randomly selected 5% probability sample of all children 5 to 17 years of age presenting to a sports medicine clinic from January 1, 2000 to December 31, 2009; 2133 charts were reviewed. Data collected included demographics, height and weight, injury mechanism, diagnosis, treatment, previous injury, and organized sports. A total of 206 ACL tears were analyzed (104 girls, 102 boys). Girls were slightly older than boys (15.1 ± 1.7 vs 14.3 ± 2.1 years; P < 0.01). Male-female comparison of ACL injury/total injury by age revealed that girls had a steeper increase by age than boys. Among 5- to 12-year-olds, boys had a higher ACL injury/total injury ratio than girls (all P < 0.01). Children 13 to 17 years of age showed no significant difference for sex in ACL injury/total injury ratio. As age advanced, the proportion of ACL injuries/total injuries increased for both girls (P < 0.01) and boys (P = 0.04). BMI was independently associated with an ACL injury (P < 0.01). The proportion of ACL injuries/total injuries was similar for boys and girls aged 13 to 17 years. Girls showed a significantly steeper increase in ACL injury proportion versus boys through puberty. This study will increase clinician awareness of ACL injury occurrence in young male and female athletes 5 to 12 years of age. Injury prevention efforts should target young girls before the onset of puberty and before injury occurs.

    Differentiating asthma from chronic obstructive pulmonary disease (COPD) is difficult. Steroid trial may be of help but has several pitfalls. The present study aims to assess the value of past clinical profile of asthma and its differential diagnosis from COPD in male smokers and thereby to formulate clinical parameters to diagnose bronchial asthma in such patients. Male smokers who reported at the Respiratory Medicine Department of the National Institute of Medical Sciences (NIMS) Hospital, Jaipur, (India), with shortness of breath (SOB) and showing less than 12% postbronchodilator bronchial reversibility (BR) on spirometry were recruited. These patients were given oral prednisolone 1 mg/kg for two weeks. Post steroid (PS) spirometry was performed to ascertain BR. The past clinical history was recorded and analyzed to determine if it is of any use in differentiating asthma from COPD. Out of 104 patients, four were lost to follow up, 52 were diagnosed as bronchial asthma, and the remaining 48 as COPD. It was revealed that past history of (H/O) seasonal variation, wheezing, eye allergy, nasal allergy, dust allergy, skin allergy, and family H/O asthma/allergy were positive in 50, 40, 34, 30, 18, 14, and 12 asthma patients as compared to 10, 8, 2, 4, 6, 0, and 0 in 48 COPD patients (P < 0.001). The odds ratio (OR) for diagnosing asthma was highest for the presence of any other two symptoms/variables, besides SOB, in the past (OR = 275, P < 0.0001). Past clinical history is of immense value in differentiating asthma from COPD in male smokers presenting with SOB and fixed airway obstruction.

  15. Runx1 Regulates Myeloid Precursor Differentiation Into Osteoclasts Without Affecting Differentiation Into Antigen Presenting or Phagocytic Cells in Both Males and Females

    Runt-related transcription factor 1 (Runx1), a master regulator of hematopoiesis, is expressed in preosteoclasts. Previously we evaluated the bone phenotype of CD11b-Cre Runx1fl/fl mice and demonstrated enhanced osteoclasts and decreased bone mass in males. However, an assessment of the effects of Runx1 deletion in female osteoclast precursors was impossible with this model. Moreover, the role of Runx1 in myeloid cell differentiation into other lineages is unknown. Therefore, we generated LysM-Cre Runx1fl/fl mice, which delete Runx1 equally (∼80% deletion) in myeloid precursor cells from both sexes and examined the capacity of these cells to differentiate into osteoclasts and phagocytic and antigen-presenting cells. Both female and male LysM-Cre Runx1fl/fl mice had decreased trabecular bone mass (72% decrease in bone volume fraction) and increased osteoclast number (2–3 times) (P < .05) without alteration of osteoblast histomorphometric indices. We also demonstrated that loss of Runx1 in pluripotential myeloid precursors with LysM-Cre did not alter the number of myeloid precursor cells in bone marrow or their ability to differentiate into phagocytizing or antigen-presenting cells. This study demonstrates that abrogation of Runx1 in multipotential myeloid precursor cells significantly and specifically enhanced the ability of receptor activator of nuclear factor-κB ligand to stimulate osteoclast formation and fusion in female and male mice without affecting other myeloid cell fates. In turn, increased osteoclast activity in LysM-Cre Runx1fl/fl mice likely contributed to a decrease in bone mass. These dramatic effects were not due to increased osteoclast precursors in the deleted mutants and argue that inhibition of Runx1 in multipotential myeloid precursor cells is important for osteoclast formation and function.

    This study examined the social environment effects during a post-match video presentation on the hormonal responses and match performance in professional male rugby union players. The study participants (n=12) watched a 1-hour video of mixed content (player mistakes and successes) from a match played 1 day earlier in the presence of; (1) strangers who were bigger (SB), (2) strangers who were smaller (SS), (3) friends who were bigger (FB) and (4) friends who were smaller (FS). The salivary testosterone (T) and cortisol (C) responses to a physical stress test were assessed 3 days later, along with pre-match T levels and match-ranked performance 6-7 days later. All treatments were associated with elevated T responses (% change from baseline) to the stress test with SS>SB and FB>FS. The C stress responses after the SS and SB interventions were both greater than FS and FB. On match-day, the FB approach was linked to higher T concentrations than SB and better ranked performance than FS and SS. The subsequent testing of a population sub-group (n=8) across a video (V) and a non-video (NV) presentation in a neutral social environment produced similar stress-test and performance outcomes, but pre-match T concentrations differed (V>NV). In conclusion, the presence of other males during a post-match video assessment had some influence on the hormonal responses of male athletes and match performance in the week that followed. Thus, the social environment during a post-match assessment could moderate performance and recovery in elite sport and, in a broader context, could be a possible modulator of human stress responses.

  17. Non-Classic Congenital Lipoid Adrenal Hyperplasia: A New Disorder of the Steroidogenic Acute Regulatory Protein With Very Late Presentation and Normal Male Genitalia

    PubMed Central

    2007-01-01

    Context Congenital lipoid adrenal hyperplasia (lipoid CAH) is a severe disorder of adrenal and gonadal steroidogenesis caused by mutations in the steroidogenic acute regulatory protein (StAR). Affected children typically present with life-threatening adrenal insufficiency in early infancy due to a failure of glucocorticoid (cortisol) and mineralocorticoid (aldosterone) biosynthesis, and 46,XY genetic males have complete lack of androgenization and appear phenotypically female due to impaired testicular androgen secretion in utero. Objective The objective of this study was to investigate whether non-classic forms of this condition exist. Patients & Methods Sequence analysis of the gene encoding StAR was undertaken in three children from two families who presented with primary adrenal insufficiency at 2-4 years of age; the males had normal genital development. Identified mutants were tested in a series of biochemical assays. Results DNA sequencing identified homozygous StAR mutations Val187Met and Arg188Cys in these two families. Functional studies of StAR activity in cells and in vitro, and cholesterol-binding assays showed these mutants retained ∼20% of wild type activity. Conclusions These patients define a new disorder, “non-classic lipoid CAH”, and represent a new cause of non-autoimmune Addison disease (primary adrenal failure). PMID:16968793

    The objectives of the current national study were to determine the rates of self-reported circumcision among South African men and, more importantly, evaluate the acceptability of male circumcision in South Africa by uncircumcised adult men and all adult women. The study based on a population-based survey included a nationally representative subgroup of 6654 men aged 15 years and older who where included in the analysis on male circumcision prevalence, and a subgroup of 6796 women aged 15 to 49 years who were included in the analysis on male circumcision acceptance. An overall prevalence of self-reported male circumcision of 42.8% was found. Among the Black African population group the prevalence of male circumcision was 48.2%, 32.1% were traditionally and 13.4% were medically circumcised. Among males not circumcised 45.7% of 15-24 years olds indicated that they would consider being circumcised compared to 28.3% among 25-49 years olds. In multivariate analysis among non-circumcised men Black African and Coloured population groups and having heard of the HIV protective effect of male circumcision were significant predictors for male circumcision acceptability, and among women with a non-circumcised sexual partner, Black African and Coloured population groups and higher education were predictors for male circumcision acceptability. The study found high rates and high acceptability of male circumcision. Findings associated with the acceptability of male circumcision can be used to increase awareness of the benefits of male circumcision for HIV prevention.

    Background In co-cultures of pachytene spermatocytes with Sertoli cells, β-NGF regulates the second meiotic division by blocking secondary spermatocytes in metaphase (metaphase II), and thereby lowers round spermatid formation. In vertebrates, mature oocytes are arrested at metaphase II until fertilization, because of the presence of cytostatic factor (CSF) in their cytoplasm. By analogy, we hypothesized the presence of CSF in male germ cells. Methodology/Principal Findings We show here, that Mos, Emi2, cyclin E and Cdk2, the four proteins of CSF, and their respective mRNAs, are present in male rat meiotic cells; this was assessed by using Western blotting, immunocytochemistry and reverse transcriptase PCR. We measured the relative cellular levels of Mos, Emi2, Cyclin E and Cdk2 in the meiotic cells by flow cytometry and found that the four proteins increased throughout the first meiotic prophase, reaching their highest levels in middle to late pachytene spermatocytes, then decreased following the meiotic divisions. In co-cultures of pachytene spermatocytes with Sertoli cells, β-NGF increased the number of metaphases II, while enhancing Mos and Emi2 levels in middle to late pachytene spermatocytes, pachytene spermatocytes in division and secondary spermatocytes. Conclusion/Significance Our results suggest that CSF is not restricted to the oocyte. In addition, they reinforce the view that NGF, by enhancing Mos in late spermatocytes, is one of the intra-testicular factors which adjusts the number of round spermatids that can be supported by Sertoli cells.

    Ovotesticular disorder of sexual differentiation (OTDSD) is a rare cause of disorder of sexual differentiation predominantly having 46,XX karyotype, female phenotype and ambiguous genitalia. We report a 15-year-old having male body habitus, axillary and pubic hair, well-developed penis and right-descended testis with history of penoscrotal hypospadias correction, presenting with three episodes of cyclical haematuria, who biochemically had normal serum testosterone (338 ng dl(-1) ) which increased following hCG stimulation (614 ng dl(-1) ), elevated estradiol (17.35 pg ml(-1) ) along with elevated luteinising hormone (11.3 mIU l(-1) ) and follicle-stimulating hormone (31 mIU l(-1) ). Ultrasonography followed by micturating cystourethrogram and cystoscopy confirmed the presence of prostate, uterus, cervix and vagina draining into the urogenital sinus continuing till the penile urethra and left intra-abdominal gonad. Patient underwent hysterectomy and left gonadectomy. Histopathologic study of resected gonad confirmed presence of ovotestis. Low estradiol (1.2 pg ml(-1) ) following gonadectomy confirmed the ovotestis origin of estradiol. Chromosomal analysis revealed complex karyotype predominant being 47,XYY (50%) followed by 46,XY (26%) and 45,X (24%). This is perhaps the first report of 47,XYY/46,XY/45,X causing OTDSD in a phenotypic male.

    Pancreatitis is a known cause of pseudoaneurysms of the peripancreatic arteries, which can rarely rupture into various adjacent structures and become a source of life-threatening bleeding. The management is challenging and requires an individualised approach and multidisciplinary care. Herein, we present the case of a 24-year-old man in whom a splenic pseudoaneurysm ruptured into the adjacent infected pseudocyst, communicating with the colon by a fistulous tract, causing massive lower gastrointestinal bleeding. This was successfully managed by transcatheter arterial embolisation (TAE). PMID:23208811

    We report a case of atypical pityriasis rosea in a 24-year-old Malay man. He presented with an 11-month history of three recurrent and persistent episodes of pityriasis rosea associated with oral ulcers. The first episode lasted for one month and recurred within 14 days. The second episode lasted for three months and recurred within nine days. The third episode lasted for seven months. Although all three episodes were not preceded by any prodromal symptoms, a herald patch was noted on three different sites (the left iliac fossa, abdomen and chest) on each successive episode. Recurrent pityriasis rosea and its association with oral ulcers, although quite uncommon, have been reported in the literature. However, reports of multiple recurrences, with prolonged duration of each episode and very short remissions in between, have not been made. To the best of our knowledge, this is the first report of such unique presentation.

    The clinical and histopathologic findings of a rare simultaneous occurrence of papulonecrotic tuberculid and nodular tuberclid in a patient with active but asymptomatic pulmonary tuberculosis are presented. Papulonecrotic tuberculid was observed at a very early stage, presenting as molluscum-like lesions. This has been described once in the literature. This was observed in conjunction with lesions compatible with the rare clinicopathologic variant of nodular tuberculid. Critical to the diagnosis of active pulmonary tuberculosis was the use of induced sputum testing, which confirmed the diagnosis despite the lack of a cough and a chest x-ray negative for active tuberculosis. A 40-year-old male presented with a 2-week history of fever and a skin eruption consisting of molluscum-like papules on the ears, arms, and abdomen and nodules on his legs. Biopsies from both lesions were consistent with papulonecrotic and nodular tuberculid, respectively. Despite the lack of any respiratory symptoms, induced sputum grew Mycobacterium tuberculosis, and the lesions resolved on antituberculous therapy. Tuberculids are rare in Western countries but must be considered in the differential diagnosis of eruptions in patients from endemic countries. An active tuberculous focus must be sought out. © 2014 Canadian Dermatology Association.

    This male patient presented with a scrotal abscess and urinary obstruction. The patient’s history included a perineal abscess and the development of urethrocutaneous fistulae (watering-can perineum). He underwent multiple debridement procedures without resolution. During the fifth debridement for Fournier’s gangrene, a biopsy revealed invasive squamous cell carcinoma. The patient was bedridden because of the large mass, a wide en bloc resection with lymphadenectomy and reconstruction was performed revealing a large (22 cm) squamous cell carcinoma originating from the urethra. He also received palliative chemoradiotherapy and hip hemiarthroplasty. Unfortunately, he succumbed to the disease. Given the recognized relationship between inflammation and the development of cancer, it is important to entertain a differential diagnosis of cancer, especially with erosive infections. This case report highlights the all too common late presentation of urethral cancer. Interestingly, despite correction of the bedridden state with palliative surgery, the patient did not perceive an improvement in quality of life based on the FACT-G questionnaire. PMID:27721660

    We present a case of a 27 year-old Malian male referred to our hospital for two large, painless retroauricolar masses that had appeared two years earlier. Bilateral cervical painless lymphadenopathy was present at physical examination, without any other systemic symptoms. His history was relevant for bilateral Kimura’s disease lesions resected 5 years earlier in the same locations. Lymphocytosis and a mild hypereosinophilia were found in routine blood tests, together with increased total IgE levels. After surgery, histology showed lymphoid infiltrates with reactive prominent germinal centres containing eosinophils, suggesting relapse of Kimura’s disease, in the context of nonencapsulated fibrous proliferation with discontinuous collagen fibers, consistent with keloid. Three months after removal of retroauricular masses, abnormal laboratory findings reverted to normal. To the best our knowledge, this is the first case in literature of bilateral keloid lesions developed after surgery for Kimura Disease and harbouring its histopathologic features. Clinicians should be aware of these unusual reactive phenomena and their possible simulators.

    A 24-year-old womanpresented with ameloblastic fibrosarcoma arising from ameloblastic fibroma. The delayed presentation accounted for the extensive destruction of the mandible and complete occlusion of her oral cavity. This resulted in an inability to eat and maintain oral hygiene. A multidisciplinary team management approach involved nutritional optimisation, segmental mandibulectomy, reconstruction with a reconstructive plate and a free anterolateral thigh flap to line the the floor of mouth. Functional and aesthetic outcome was acceptable, and the patient is planned for secondary free fibular flap bony reconstruction. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    Becker nevus syndrome (BNS) is a rare epidermal nevus syndrome characterized with Becker nevus and ipsilateral breast gland hypoplasia or other skin, skeletal and/or muscle tissue disorders. A 24-year-old woman presented with brown, irregular bordered patch with a diameter of approximately 10 cm which consisted of several small macules on the left breast skin. The ultrasonography and magnetic resonance imaging revealed left breast hypoplasia. Histopathological examination demonstrated minimal acanthosis, papillomatosis, increase in basal layer melanin and hypertrophy of the erector pili muscle. Immunohistochemical staining was positive for androgen in the epidermis, dermal stromal cells and skin appendages. Depending on the clinical and histopathological findings, the patient was diagnosed as BNS. Diagnosis of BNS needs careful examination of pigmented macules and patches since non-hairy BN may be easily overlooked. Patients with BN should be evaluated for associated abnormalities of BNS, in which the severity and extend of ectodermal involvement may differ from patient to other. PMID:25484431

    Introduction Sildenafil (Viagra®) is one of the drugs used in the first line therapy of male erectile dysfunction (MED). We have recorded outcomes, adverse events and acceptability of Sildenafil (Viagra) therapy in an unselected group of men presenting with ED to a British district general hospital. Methods In this prospective observational study, 147 men with ED were seen since Oct 1999. Study patients were reviewed at 4, 12 and 52 weeks. All the patients filled the International Index of Erectile Function (IIEF) questionnaire and were asked about their willingness to pay (WTP) for treatment. Results All suitable men accepted Viagra as first line therapy. 91% of our patients found sildenafil treatment successful. 80% of these patients were willing to continue with sildenafil therapy. Side effect profile of sildenafil was different in this study with much higher incidence of headache, dyspepsia, flushing and abnormal vision. 92% of men with ED expect to be treated by the NHS. Of those men eligible for treatment in the NHS, 30% qualify under the clinical categories and 18% under the 'distress' category. Only 55% of those with cardiovascular risk factors qualify for NHS treatment. Conclusions Sildenafil is widely accepted as first line therapy among British men with ED and has a success rate of 91%. Nearly half of men with ED qualify for NHS treatment. Nearly half of those with vascular risk factors do not qualify for NHS treatment. Most men with ED could possibly be managed in primary care.

    Introduction Androgens have been implicated in both male pattern baldness (MPB) and prostate cancer (PCa). We set out to prospectively determine if men with independently assessed MPB are at higher risk for PCa at biopsy and determine if any grade associations exist. Methods We prospectively enrolled 394 eligible patients presenting for prostate biopsy and independently determined their MPB pattern using the validated modified Norwood classification system (0: no balding; 1: frontal balding; 2: mild vertex balding; 3: moderate vertex balding; 4: sever vertex balding). Univariate and multivariable models, including Norwood score, age, prostate-specific antigen, and digital rectal examination abnormalities, were calculated for the outcomes of cancer and high-grade disease (Gleason >6). C-statistics analyses of our models were then compared with and without MPB pattern for marginal utility. Results Norwood patterns were increasingly associated with cancer and high-grade disease with a dose-effect (p for trend <0.001 on univariate and multivariable analyses for cancer and p=0.001 and p=0.0036 for high-grade disease on univariate and multivariable analyses, respectively). On multivariable analyses, trends still held, with all patients exhibiting Norwood scale 3 and 4 at increased risk for cancer. In predicting risk of high-grade disease, only patients with Norwood pattern 4 exhibited an increased risk. Conclusions MPB appears to be a strong and independent risk factor for both cancer and high-grade disease for men presenting for prostate biopsy. Ours could be superior to marketed costly genetic tests. Further research is needed to understand the biology behind this observation and to incorporate these findings into clinical decision-making.

  11. Properties of a Novel pH-dependent Ca2+ Permeation Pathway Present in Male Germ Cells with Possible Roles in Spermatogenesis and Mature Sperm Function

    Rises of intracellular Ca2+ ([Ca2+]i) are key signals for cell division, differentiation, and maturation. Similarly, they are likely to be important for the unique processes of meiosis and spermatogenesis, carried out exclusively by male germ cells. In addition, elevations of [Ca2+]i and intracellular pH (pHi) in mature sperm trigger at least two events obligatory for fertilization: capacitation and acrosome reaction. Evidence implicates the activity of Ca2+ channels modulated by pHi in the origin of these Ca2+ elevations, but their nature remains unexplored, in part because work in individual spermatozoa are hampered by formidable experimental difficulties. Recently, late spermatogenic cells have emerged as a model system for studying aspects relevant for sperm physiology, such as plasmalemmal ion fluxes. Here we describe the first study on the influence of controlled intracellular alkalinization on [Ca2+]i on identified spermatogenic cells from mouse adult testes. In BCECF [(2′,7′)-bis(carboxymethyl)- (5,6)-carboxyfluorescein]-AM-loaded spermatogenic cells, a brief (30–60 s) application of 25 mM NH4Cl increased pHi by ∼1.3 U from a resting pHi ∼6.65. A steady pHi plateau was maintained during NH4Cl application, with little or no rebound acidification. In fura-2-AM-loaded cells, alkalinization induced a biphasic response composed of an initial [Ca2+]i drop followed by a two- to threefold rise. Maneuvers that inhibit either Ca2+ influx or intracellular Ca2+ release demonstrated that the majority of the Ca2+ rise results from plasma membrane Ca2+ influx, although a small component likely to result from intracellular Ca2+ release was occasionally observed. Ca2+ transients potentiated with repeated NH4Cl applications, gradually obliterating the initial [Ca2+]i drop. The pH-sensitive Ca2+ permeation pathway allows the passage of other divalents (Sr2+, Ba2+, and Mn2+) and is blocked by inorganic Ca2+ channel blockers (Ni2+ and Cd2+), but not by the organic

    Currently approved male-directed contraceptive methods include condoms and vas occlusion. Vas occlusion is very effective but is intended to be non-reversible. Condoms have a relatively high failure rate, at least partially due to compliance problems and are not accepted by many couples. The only other male-oriented methods in clinical trials utilize the administration of testosterone alone or its combination with another gonadotropin-suppressing agent such as a progestin or a gonadotropin-releasing hormone antagonist. Studies published in the 1990s demonstrated that a testosterone-containing hormonal contraceptive method suppressed spermatogenesis to azoospermia in most men and severe oligozoospermia in the remaining. The contraceptive efficacy after treatment with testosterone alone was comparable to that of female hormonal methods. Having proven that reversible male contraception is a reality, present trials are attempting to identify the best androgen delivery system and the most effective androgen plus progestin preparation. It is likely that the first marketed male hormonal contraceptive method will be a long-acting (injectable or implant) combination of an androgen plus a progestin. Research is continuing to identify other target areas for male contraceptive development, including agents with post-testicular and epididymal sites of action.

    Each year in India, road traffic crashes lead to more than 200,000 deaths and the country has seen an unprecedented rate of roadway fatalities in recent years. At the same time, alcohol consumption per capita among Indians is rising. Despite these increasing trends of road traffic injuries (RTIs) and alcohol use, alcohol is not routinely assessed as a risk factor for RTIs. This study aims to examine the involvement of alcohol among emergency department patients presenting with RTIs in the Indian city of Hyderabad. As part of a prospective study, data were collected from 3366 patients (88.0% male) presenting with RTIs at an emergency department in Hyderabad, India, from September 2013 to February 2014. Logistic regression models were used to assess individual-level and road traffic crash characteristics associated with suspected or reported alcohol consumption six hours prior to the RTI. Alcohol was suspected or reported among 17.9% of the patients with RTIs. Adjusting for confounders, males experienced 9.8 times greater odds of alcohol-related RTIs than females. Compared to 15-24 year-olds, the odds of alcohol consumption was 1.4 times greater among 25-34 year-olds and 1.7 times greater among 35-44 year-olds, adjusting for confounding factors. Patients who were passengers in vehicles other than motorized two-wheelers had 90% reduced odds of an alcohol-related RTI than motorized two-wheeler drivers. Drivers of non-two-wheelers, passengers on two-wheelers, and pedestrians did not have significantly different odds of an alcohol-related RTI compared to two-wheeler drivers. Nighttime crashes were associated with nearly a threefold increase in the odds of alcohol consumption. Given that alcohol was suspected or reported in more than one in six injured ED patients with RTIs, it is clear that alcohol is a serious risk factor for RTIs; this evidence can guide prevention efforts. These findings suggest that evidence-based interventions to reduce drink-driving, such as random

    Anomalous origination of coronary artery from the opposite sinus (ACAOS) is a rare coronary artery anomaly. Right ACAOS with interarterial course is a type of ACAOS, which conveys a high risk for myocardial ischemia or sudden death. We reported a case of right ACAOS with interarterial course in otherwise healthy young male. He was asymptomatic, until an obligatory medical check-up with treadmill test showed a sign of positive ischemic response. Further work-up revealed that he had right ACAOS with interarterial course. Watchful observation was applied to him, while strenuous physical activity and competitive sport were absolutely prohibited. PMID:26885410

    Male germ-cell apoptosis occurs naturally and can be increased by exposure to drugs and toxic chemicals. Individuals may have different rates of apoptosis and are likely to also exhibit differential sensitivity to outside influences. Previously, we reported that p-chloroamphetamine (pCA), a substance that inhibits serotonin synthesis, induced germ-cell apoptosis in prepubertal male rats. Here, we identified prepubertal rats with naturally high or low rates of germ-cell apoptosis and evaluated gene expression in both groups. Bax and Shbg mRNA levels were higher in rats with high rates of germ-cell apoptosis. Rats were then treated with pCA and the neuro-hormonal response and gene expression were evaluated. Treatment with pCA induced a reduction in serotonin concentrations but levels of sex hormones and gonadotrophins were not changed. Rats with initially high rates of germ-cell apoptosis had even higher rates of germ-cell apoptosis after treatment with pCA. In rats with high rates of germ-cell apoptosis Bax mRNA expression remained high after treatment with pCA. On the basis of category, an inverse relationship between mRNA expression of Bax and Bcl2, Bax and AR and Bax and Hsd3b2 was found. Here we provide evidence that innate levels of germ-cell apoptosis could be explained by the level of mRNA expression of genes involved with apoptosis and spermatogenesis.

    Few children consume the recommended portions of fruit or vegetables. This study examined the effects of parental physical prompting and parental modelling in children's acceptance of a novel fruit (NF) and examined the role of children's food-approach and food-avoidance traits on NF engagement and consumption. A total of 120 caregiver-child dyads (fifty-four girls, sixty-six boys) participated in this study. Dyads were allocated to one of the following three conditions: physical prompting but no modelling, physical prompting and modelling or a modelling only control condition. Dyads ate a standardised meal containing a portion of a fruit new to the child. Parents completed measures of children's food approach and avoidance. Willingness to try the NF was observed, and the amount of the NF consumed was measured. Physical prompting but no modelling resulted in greater physical refusal of the NF. There were main effects of enjoyment of food and food fussiness on acceptance. Food responsiveness interacted with condition such that children who were more food responsive had greater NF acceptance in the prompting and modelling conditions in comparison with the modelling only condition. In contrast, children with low food responsiveness had greater acceptance in the modelling control condition than in the prompting but no modelling condition. Physical prompting in the absence of modelling is likely to be detrimental to NF acceptance. Parental use of physical prompting strategies, in combination with modelling of NF intake, may facilitate acceptance of NF, but only in food-responsive children. Modelling consumption best promotes acceptance in children with low food responsiveness.

    The integrity of the urogenital tract against potentially invasive pathogens is important for the health of the individual, fertilization, and continuance of species. Antibiotic peptides with broad antimicrobial activity, among them chemokines, are part of the innate immune system. We investigated the presence of the antibacterial interferon (IFN)-dependent CXC chemokines, MIG/CXCL9, IP-10/CXCL10, and I-TAC/CXCL11, in the human male reproductive system. MIG/CXCL9 was detected at 25.0 nM (range 8.1-40.6 nM; n = 14), whereas IP-10/CXCL10 and I-TAC/CXCL11 were detected at lower levels (mean 1.8 nM, range 0.3-5.8 nM and mean 0.6, 0.2-1.6 nM, respectively) in seminal plasma of fertile donors. The levels of MIG/CXCL9 are more than 300-fold higher than those previously reported in blood plasma. In vasectomized donors, significantly lower levels of MIG/CXCL9 (mean 14.7 nM, range 6.6-21.8) were found, suggesting that the testis and epididymis, in addition to the prostate, significantly contribute to the MIG/CXCL9 content of seminal plasma. Strong expression of MIG/CXCL9 was found in the epithelium of testis, epididymis, and prostate, as detected by immunohistochemistry. MIG/CXCL9 at concentrations in the order of those found in seminal plasma possessed antibacterial activity against the urogenital pathogen Neisseria gonorrhoeae. The relatively high levels of MIG/CXCL9 in seminal plasma point to roles for this chemokine in both host defense of the male urogenital tract and during fertilization.

    A literature review and case presentation are used to discuss the diagnostic value of spectral domain optical coherence tomography (SD-OCT) in the assessment and management of congenital achromatopsia. A 24-year-old Hispanic man presented to the clinic with a longstanding history of decreased vision and associated possible recent progression. A comprehensive eye examination and a battery of tests including SD-OCT, fundus photography, electroretinogram (ERG) and Farnsworth D-15 were completed. SD-OCT and photopic ERG confirmed the clinical diagnosis of congenital achromatopsia. There was the classic subfoveal flattened hyporeflective 'punched out' zone, resulting from an absence of inner segment/outer segment junction. SD-OCT findings associated with congenital achromatopsia have been documented recently, helping in the diagnosis of the condition. The SD-OCT findings have further expanded our knowledge of congenital achromatopsia, while also aiding in the management of the disease.

    Kawasaki Disease (KD) is an acute systemic vasculitis of unknown etiology. In many developed countries, KD has replaced rheumatic heart disease as the leading cause of acquired heart disease in children. Among the classical criteria for a diagnosis of KD are oral manifestations such as strawberry tongue, erythematous cracked lip, and oropharyngeal mucositis. We report the case of a 24-year-old Saudi female with a history of Kawasaki disease who presented to our oral medicine clinic with recurrent painless swelling of the upper lip. As lip swelling has not previously been reported as an oral manifestation of KD, this case represents a novel presentation of recurrent Kawasaki disease in an adult female.

    2017-01-03

    Canadian media discourses on gay men's sexuality and political inclusion serve as a rich site for understanding current tensions in debates on sexual citizenship under biopolitical regimes. This paper addresses how public health reporting in one health news media source, Canada's leading newspaper The Globe and Mail, discursively produced contiguous understandings of the moral, social and biological dimensions of gay male subjectivity and sexuality within the context of HIV risk discourses. Specifically, we critically examine the newspaper's coverage of what constitutes the public good when national blood supplies are at stake. Our analysis reveals a profound dichotomy in which gay men - as sexual subjects and subjects of rights - are recalibrated following the political and economic investments of bourgeoisie communities of interest. However encompassing the securing of legal social rights might be, gay men's sexuality is resistant to a reformatting under a heteronormative regulatory regime, as the social traumas caused by HIV continue to cast a shadow on sexual behaviours that purportedly risk leakage of contamination into the body politic.

    Homozygous deficiencies of early components for complement activation are among the strongest genetic risk factors for human systemic lupus erythematosus (SLE). Eleven cases of C1r deficiency are documented but this is the first report on the molecular basis of C1r deficiency. The proband is an African-American male who developed SLE at 3 months of age. He had a discoid lupus rash and diffuse proliferative glomerulonephritis. Serum complement analysis of the patient showed zero CH50 activity, undetectable C1r, and reduced levels of C1s, but highly elevated levels of complement C4, C2, and C1-inhibitor. The coding regions of the mutant C1R gene with 11 exons located at chromosome 12p13 were polymerase chain reaction (PCR)-amplified and sequenced to completion. DNA sequencing revealed a homozygous C→T mutation at nucleotide-6392 in exon 10 of the C1R gene, resulting in a nonsense mutation from Arg-380 (R380X). The patient's clinically normal mother was heterozygous for this mutation. A sequence-specific primer (SSP) PCR coupled with StuI-restriction fragment length polymorphism (RFLP) was developed to detect the novel mutation. Screening of 209 African-American SLE patients suggested that the R380X mutation is a rare causal variant. Mutations leading to early complement component deficiencies in SLE are mostly private variants with large effects.

  9. Acute behavioural effects of bupropion and naltrexone, alone and in combination, in non-deprived male rats presented with palatable mash.

    2013-07-01

    In appetite research, drugs frequently progress to clinical trials on the basis of outcome (reduced food intake/body weight gain) with insufficient attention to process (behavioural analysis). Although bupropion and naltrexone (alone and in combination) reduce food consumption in rodents and humans, their effects on behaviour during feeding tests have not been thoroughly investigated. This study aimed to assess the behavioural specificity of anorectic responses to bupropion, naltrexone and their combination. Video analysis was employed to characterise the behavioural effects of acute systemic treatment with bupropion (10.0-40.0 mg/kg), naltrexone (0.1-3.0 mg/kg) and combined bupropion (20 mg/kg) plus naltrexone (0.1-1.0 mg/kg) in non-deprived male rats exposed for 1 h to palatable mash. Particular attention was paid to the behavioural satiety sequence (BSS). In experiment 1, the anorectic response to 40 mg/kg bupropion was associated with significant psychomotor stimulation and a complete disruption of the BSS. In experiment 2, the anorectic response to 3 mg/kg naltrexone was associated with an accelerated but otherwise normal BSS. In experiment 3, the co-administration of 20 mg/kg bupropion and naltrexone (0.1 and 1.0 mg/kg) not only produced an additive anorectic profile (including a reduced rate of eating), but the addition of the opioid receptor antagonist also concurrently attenuated the psychomotor stimulant response to the atypical antidepressant. Low-dose co-treatment with naltrexone and bupropion produces a stronger suppression of appetite than that seen with either agent alone and has the additional advantage of reducing some of the unwanted effects of bupropion.

    Delayed hemothorax after blunt torso injury is rare, but might be associated with significant morbidity and mortality. We present a case of delayed hemothorax bleeding from phrenic artery injury in a 24-year-old woman. The patient suffered from multiple rib fractures on the right side, a right hemopneumothorax, thoracic vertebral injury and a pelvic bone fracture after a fall from a fourth floor window. Delayed hemothorax associated with phrenic artery bleeding, caused by a stab injury from a fractured rib segment, was treated successfully by a minimally invasive thoracoscopic surgery. Here, we have shown that fracture of a lower rib or ribs might be accompanied by delayed massive hemothorax that can be rapidly identified and promptly managed by thoracoscopic means. PMID:27051252

    Complex forms of spastic paraplegia (SPG) are rare and genetically heterogeneous. In apparently sporadic cases, analysis of known SPG genes often fails to reveal a mutation. We report a 24-year-old patient with a syndrome of spastic paraplegia, ataxia, frontotemporal dementia, and lower motor neuron involvement. Screening of the patient's genome for copy number variation identified a novel 276 kb deletion spanning the first exon of the GRID2 gene. MRI scan showed atrophy of the cerebellum, and electromyography revealed a chronic disorder of motor neurons or their axons. A deletion in GRID2, coding for the glutamate receptor delta-2 subunit precursor protein, was excluded in either parent, suggesting that the deletion in the index patient occurred de novo. We hypothesize that the deletion identified here is the cause of our patient's clinical presentation, due to the resemblance to the GRID2 mutation phenotype in mouse models.

    Patients with inadequately controlled or uncontrolled asthma are at a greater risk of attacks for asthma requiring emergency room visits or hospital admissions. There is a significant correlation between the severity of the disease and the severity of exacerbations. Patients with poorly controlled asthma are at a higher risk for complications. We present a 24-year-old aspirin-intolerant, uncontrolled asthma patient with the complication of pneumomediastinum. Severe symptoms persisted after the resolution of the pneumomediastinum despite intense anti-inflammatory and anti-obstructive therapy. A bronchoscopy revealed an endobronchial lesion and she was diagnosed with a carcinoid tumor. This case is an example of the importance of re-evaluating asthma patients who do not respond to standard medical treatment. Clinicians should be aware of the complications associated with asthma attacks such as pneumomediastinum and the possibility of a differential diagnosis that worsen asthma symptoms such as a carcinoid tumor.

  13. EBUS-FNA of a station seven lymph node: an unusual presentation of a young nonsmoker male with hemoptysis and subcarinal lymphadenopathy.

    Endobronchial ultrasound-guided fine needle aspiration (EBUS-FNA) is a safe and minimally invasive bronchoscopic technique that allows both visualization and cytologic sampling with a high diagnostic yield in a patient with mediastinal lymphadenopathy. Besides the most common indication of staging for a patient with a primary lung carcinoma, EBUS-FNA can be used to identify benign infectious and noninfectious processes as well as lymphoma and malignancy of unknown primary. Triaging of procured specimen for diagnostic, prognostic, and therapeutic ancillary studies requires appropriate clinical information at the time of rapid on site evaluation (ROSE) of smears. This case report demonstrates a young, previously healthy nonsmoker presenting clinically with cough, hemoptysis, and a 1.7 cm enlarged subcarinal lymph node by imaging. EBUS-FNA obtained smears from the lymph node revealed a pleomorphic population of smaller cells with a low nuclear to cytoplasmic ratio and prominent nucleoli, and larger cells had nuclei with bizarre shapes, mitoses, multinucleation, enlarged nucleoli, and pigmentation in a background of lymphocytes. The cytomorphologic and immunohistochemical workup of this case confirmed the unexpected diagnosis of metastatic melanoma. This result was a complete surprise to the clinical team managing the patient and prompted a thorough clinical workup. Subcarinal lymphadenopathy with metastatic malignant melanoma as the cause is rare. This case report highlights how ROSE and appropriate triaging of specimen were crucial in appropriately working up this case. We also survey the literature to review the reported unusual presentations of metastatic melanoma.

    A two-year-old African American boy presented with cutaneous xanthomata and extreme hypercholesterolemia. Subsequent studies revealed that the LDL-cholesterol was 1,001 mg/dl and apoB 507 mg/dl. LDL-receptor activity was almost undetectable, which is compatible with the finding of two newly described defective alleles on exon 4 of the LDL-receptor gene coding for part of the ligand-binding domain. One allele contained a 21 base-pair insertion from codon 200 to 207 whereas the other had a point mutation at codon 207. The rarity of genes for FH reported in individuals of African ancestry is discussed. 16 refs., 2 figs., 2 tabs.

    Several findings suggest that there may be an overlap of anti-N-methyl-d-aspartate receptor (NMDAR) antibody encephalitis with neuromyelitis optica spectrum disorders or acute demyelinating encephalomyelitis (ADEM)-like demyelination. We present a case of a patient with anti-NMDAR antibody encephalitis, who on MRI featured a single prominent T2-hyperintensive white matter lesion in the periventricular region, adjacent to the anterior horn of the left lateral ventricle. In view of the lesion location and the cerebrospinal fluid (CSF) findings (incomplete MRZ (measles, rubella and varicella zoster) reaction, lymphocytic pleocytosis, intrathecal IgG and IgM synthesis; absence of aquaporin-4 (AQP4) and myelin oligodendrocyte glycoprotein (MOG) antibodies), the presence of a multiple sclerosis-like immune response was discussed. This case appears to add evidence to the hypothesis of an overlap between anti-NMDAR antibody encephalitis and other inflammatory central nervous system diseases. 2015 BMJ Publishing Group Ltd.

    HIV incidence is increasing among 13-24-year-old U.S. men who have sex with men, yet limited research is available to guide HIV prevention efforts for this population. National Survey of Family Growth data collected in 2002, in 2006-2010 and in 2011-2013 from 8,068 males aged 15-24 were analyzed to describe the population of U.S. young sexual minority males (i.e., males reporting same-sex attraction, identity or behavior). Correlates of sexual minority classification were assessed in logistic regression models. An estimated 10% of young males, representing a population of 2.1 million, were sexual minorities. Males had an elevated likelihood of being sexual minorities if they were aged 18-19 or 20-24, rather than 15-17 (prevalence ratio, 1.7 for each); belonged to nonblack, non-Hispanic racial or ethnic minority groups (1.6); had no religious affiliation, rather than considering religion very important (1.9); or lived below the federal poverty level (1.3). They had a reduced likelihood of being sexual minorities if they lived in metropolitan areas outside of central cities (0.7). Among young sexual minority males, 44% were 15-19 years old, 29% were poor and 59% resided outside central cities. Forty-seven percent had engaged in same-sex behavior. Of those with data on all measured dimensions of sexuality, 24% reported same-sex attraction, identity and behavior; 22% considered themselves heterosexual, yet had had a male sex partner. Future investigations can further explore subpopulations of young sexual minority males and assess sexual trajectories, resilience and HIV risk. Copyright © 2016 by the Guttmacher Institute.

  17. Gender differences in the human cerebral cortex: more neurons in males; more processes in females.

    This study's objective was to investigate morphometric gender differences of the cerebral cortex in six males and five females, 12 to 24 years old. Though human brains lack sexual dimorphism on routine neuropathologic examinations, gender-specific brain weight, functional, and morphologic differences exist, suggesting that cortical differences may be found. Yet the cerebral cortex may be exempt from gender differences, as demonstrated by the fact that normal males and females perform comparably on intelligence tests. Stereologic morphometry on standardized histologic sections from 30 bilateral cortical loci determined cortical thickness, neuronal density, and derived neuronal number estimates. The mean +/- SD cortical thickness of the 60 loci examined was similar in males and females with right and left hemispheric gender ratios being balanced. In contrast, the average neuronal density of the same 60 loci was significantly higher in the male group than in the female group, and the corresponding mean male-to-female ratios were 1.18 in the right and 1.13 in the left hemisphere, which differ significantly from each other and from the balanced cortical thickness ratios. Estimates of neuronal numbers -- the product of neuronal thickness times density -- were 13% higher in males than in females, with mean male-to-female ratios of 1.13 in both hemispheres. The data provide morphologic evidence of considerable cerebral cortical dimorphism with the demonstration of significantly higher neuronal densities and neuronal number estimates in males, though with similar mean cortical thickness, implying a reciprocal increase in neuropil/neuronal processes in the female cortex.

    Patient: Female, 24 Final Diagnosis: Pinworms infection Symptoms: Abdominal pain • bloating Medication: — Clinical Procedure: Colonoscopy and biopsy Specialty: Gastroenterology and Hepatology Objective: Rare disease Background: Inflammatory bowel disease (IBD) is well recognized in developed countries and is generally among the differential diagnoses of young patients presenting with refractory diarrhea once other more common etiologies have been excluded. Pinworm infections, on the other hand, are not as common among adults in the United States. Case Report: Based on computed tomography features, a 24-year-old female patient with a history of multiple autoimmune disorders presented with abdominal pain and was diagnosed recently with Crohn’s disease. Colonoscopy was significant for pinworms seen throughout the colon. Colonic biopsy was negative for inflammatory bowel disease (IBD)-related changes. Conclusions: The diagnosis of IBD is a serious label that requires biopsy confirmation before committing to possibly lifelong treatment and possible adverse effects. Even in the most typical patient and when the presentation and imaging are classical, uncommon conditions (like Enterobius infection in this case) may preclude appropriate diagnosis and management.

    Gonorrhea is one of the most common sexually transmitted diseases in the US with 700,000 annual cases. Although most cases of gonorrhea are localized, approximately 0.5–3% become disseminated. Here we discuss a rare case of a patient with systemic lupus erythematosus (SLE) who developed septic shock from disseminated gonorrhea infection (DGI). Our patient is a 24-year-old woman with SLE, mixed connective tissue disease with cutaneous vasculitis, and lupus nephritis who presented with several weeks of malaise and generalized body aches associated with a diffuse rash along her fingers, palms, and trunk. Infectious workup was unrevealing with the exception of a positive gonorrhea test obtained from a cervical swab. Given her symptoms of tenosynovitis, the appearance of her skin lesions, and her positive gonorrhea test, she was diagnosed with septic shock secondary to DGI. With antibiotic treatment, the patient reported a dramatic improvement of the pain in her swollen joints and her rash receded. Patients diagnosed with SLE carry an increased risk of gonorrhea regardless of whether or not they are being treated for their SLE. Although it is well-documented that SLE is associated with severe DGI, few describe it resulting in overt septic shock. PMID:25024709

    It should be recognized that sexuality in the aging male is of such import that a complete sexual history must be performed. By taking a complete sexual history, facts can be obtained that will allow for appropriate focus relating to a holistic evaluation and will enable us to dispel antiquated sexual myths pertaining to the aging male. If initiated by the history taker, questions concerning sexuality may be discussed more comfortably by the patient. Erectile dysfunction, male sexual response cycle, testosterone, sexually transmitted diseases, human immunodeficiency virus, long-term illness, along with religion and culture are explored in this article with the aim of improving one's knowledge base, self reflection, and awareness of the importance of male sexuality. A complete understanding and appreciation of the aging male's medical history, surgical history, social history, and emotional history as well as his sexual, cultural, and religious concepts will allow the health care provider to better analyze information, and to recommend and provide appropriate advice and treatment to the aging male patient.

    1992-01-01

    This paper deals with male impotence in relation to love. A detailed clinical presentation attempts to show how the symptom was embedded in faulty processes of separation-individuation, whereby regression in the service of intercourse, passion and love is hindered by the fears and fantasies underlying merging experiences. These problems are examined as they appear interwoven in transference and counter-transference phenomena. The clinical case presentation is followed by a discussion of different forms of male impotence from a more general viewpoint; its relation not only to castration and phallic anxiety, but also to earlier developmental aspects. Finally, some reflections about male and female gender differences in relation to symbiotic experience.

    Male baldness is very common. Its effect on individuals is extremely variable, and in some people it will have a significant adverse effect on their quality of life. The objectives of this article are to help general practitioners (GPs) be aware of potential health problems related to male baldness, to have an approach to assessing hair loss and to be aware of treatment options. Male baldness is, most often, a normal occurrence, but it may have significant effects on a man's health. It may also be a pointer to other potential health issues. The GP is in the ideal position to conduct an initial evaluation, consider other health issues and advise on treatment options.

    Li, Yongle; Wu, Chengcheng; Liu, Wennan

    2017-01-01

    Abstract Rationale: Coronary artery ectasia (CAE) is characterized by an abnormal dilatation of the coronary arteries. CAE is often associated with the presence of slow coronary flow and may lead to acute myocardial infarction (AMI), even without total occlusion. Patient concerns and diagnosis: We report a case of a 24-year-old male patient with CAE suffering from AMI. Interventions: Percutaneous coronary intervention with aspiration thrombectomy failed to restore adequate blood flow. Heparin and antiplatelet treatment were provided for pharmacological management, but follow-up angiography 15 days later still revealed a poor result. This patient was ultimately treated with antiplatelet therapy in combination with warfarin treatment. Outcomes: Follow-up coronary angiography 15 months later showed a restored normal Thrombolysis In Myocardial Infarction grade (TIMI) 3 flow. Lessons: CAE-related infarct is often associated with high-burden thrombus formation. Long-term warfarin in combination with antiplatelet therapy may be a good alternative intervention to decrease thrombus burden and enhance blood flow. PMID:28121950

  10. Male circumcision.

    PubMed

    2012-09-01

    Male circumcision consists of the surgical removal of some, or all, of the foreskin (or prepuce) from the penis. It is one of the most common procedures in the world. In the United States, the procedure is commonly performed during the newborn period. In 2007, the American Academy of Pediatrics (AAP) convened a multidisciplinary workgroup of AAP members and other stakeholders to evaluate the evidence regarding male circumcision and update the AAP's 1999 recommendations in this area. The Task Force included AAP representatives from specialty areas as well as members of the AAP Board of Directors and liaisons representing the American Academy of Family Physicians, the American College of Obstetricians and Gynecologists, and the Centers for Disease Control and Prevention. The Task Force members identified selected topics relevant to male circumcision and conducted a critical review of peer-reviewed literature by using the American Heart Association's template for evidence evaluation. Evaluation of current evidence indicates that the health benefits of newborn male circumcision outweigh the risks; furthermore, the benefits of newborn male circumcision justify access to this procedure for families who choose it. Specific benefits from male circumcision were identified for the prevention of urinary tract infections, acquisition of HIV, transmission of some sexually transmitted infections, and penile cancer. Male circumcision does not appear to adversely affect penile sexual function/sensitivity or sexual satisfaction. It is imperative that those providing circumcision are adequately trained and that both sterile techniques and effective pain management are used. Significant acute complications are rare. In general, untrained providers who perform circumcisions have more complications than well-trained providers who perform the procedure, regardless of whether the former are physicians, nurses, or traditional religious providers.

    This study aimed to examine the role of psychological distress in the relationships between sociocultural influences (social pressure to be thin and weight teasing) and disordered eating. Data were collected from 584 university students (59.4% females and 40.6% males), aged 18-24 years old (M=20.6, SD=1.4), selected from four universities in the Klang Valley, Malaysia. Participants completed four standardized questionnaires which measured social pressure to be thin, weight-related teasing, psychological distress and disordered eating. A good fit structural equation modeling (SEM) model was developed for both sexes. For males, the SEM model revealed that sociocultural influences showed an indirect effect on disordered eating through psychological distress. For females, the model showed an indirect effect of sociocultural influences on disordered eating through psychological distress, as well as a direct effect of sociocultural influences on disordered eating. In conclusion, psychological distress mediated the relationships between sociocultural influences and disordered eating in both males and females. Our results suggest that disordered eating intervention programs on reducing psychological distress in university students may be beneficial.

    As a result of population ageing worldwide, osteoporotic fractures are becoming a serious problem in the western world. Osteoporotic fractures are associated with a significant burden in terms of morbidity, mortality, and economic costs. Although less frequent than in women, male osteoporosis is also a relatively common problem. Since bone loss and fragility fractures in men have been recognized as a serious medical condition, over the last two decades several studies have investigated a number of aspects related to the pathogenesis, diagnosis and assessment, prevention and treatment of male osteoporosis. A better understanding of factors underlying increased bone fragility in men has led to the definition of appropriate screening and diagnostic strategies, and the development of treatments that have shown to improve bone mineral density and, in some cases, reduce fracture risk in men as well as in women. This review will summarize recent findings on male osteoporosis with a particular focus on risk factors and causes of bone loss, and available therapeutic options.

    The association between microchimerism acquired primarily through pregnancy and later disease is of increasing scientific interest. Because this line of research is new and little is known about the nature of microchimerism, studies of microchimerism are potentially vulnerable to error from confounding and reverse causation. To address the issue of confounding, we conducted an analysis of predictors of male microchimerism in 272 female participants of the Danish Diet, Cancer and Health cohort. Buffy coat DNA was tested for Y chromosome presence as a marker of male microchimerism. First, we used logistic regression and thereafter random forest modeling to evaluate the ability of a range of reproductive, lifestyle, hospital or clinic visit history, and other variables to predict whether women tested positive for male microchimerism. We found some indication that current use of contraceptive pills and hormone replacement therapy reduced the odds of testing positive for male microchimerism. However, prediction of male microchimerism presence was poor based on the available variables. Studies of the possible role of male microchimerism in maternal health and disease are therefore unlikely to be heavily confounded by the variables examined in the present investigation. More research focused on acquisition, retention and clearing of male cells in the maternal circulation is needed. PMID:22926759

    Methamphethamine (TIK) is a highly addictive drug that acts as a stimulant for the central nervous system. It increases wakefulness and physical activity and can cause cardiac dysrhythmias, hypertension, hallucinations and violent behavior. Dental patients abusing methamphetamine often present with poor oral hygiene, xerostomia, rampant caries ("meth mouth") and excessive tooth wear. Management of these conditions is often challenging. A 24-year-old Caucasian man presented with severe dental pain, halitosis and self-reported poor dental appearance. A comprehensive examination including his medical history, panoramic radiographs and extra- and intraoral examination revealed 19 carious and erosive lesions. He reported using methamphetamine for eleven years and had not experienced much caries prior to using the drug. The patient's medical and dental histories along with radiographic and clinical findings led to a diagnosis of "meth mouth." Although various dental treatment options were offered to the patient, he opted for extraction of the most painful teeth in the left lower madibular quadrant and has yet to return for further treatment. This literature review and clinical case description of the oral manifestations of "meth mouth" is intended to alert dental practitioners to recognize and manage patients who are abusing methamphetamines. They should also be aware that these patients are often unreliable at following prevention advice as well as keeping follow-up appointments.

    Except for condoms, male contraception is very slightly utilized in France. Several male experimental methods are under study. A synthetic luteinizing hormone-releasing hormone (LHRH) analog has been used successfully in women and offers promise in men of blocking LHRH and thus blocking spermatogenesis. Several nonsteroid substances such an hypertensives and adrenaline would suppress follicle stimulating hormone and luteinizing hormone release, but are too toxic for use. The combination of 40 mcg ethinyl estradiol and 20 mg of methyltestosterone inhibits gonadotropin release and produces azoospermia in men, but at the risk of loss of libido, constant gynecomastia, and testicular atrophy. Several combinations of androgens and progestins have been evaluated. Percutaneous testosterone and medroxyprogesterone acetate appears to be the most effective, with good metabolic tolerance and maintenance of libido and sexual performance. Injections of inhibine, a testicular factor that controls secretion of follicle stimulating hormone by feedback, offer promise of suppressing spermatogenesis without affecting other systems. Numerous substances are known to inhibit spermatogenesis but are to toxic for use or entail an unacceptable loss of libido. Gossypol has been employed as a contraceptive by the Chinese for its action in inhibiting protein synthesis, but it is known to have serious secondary effects. Among male methods currently in use, the condom had a Pearl index of .4-1.6 in the most recent British studies. Coitus interruptus can seriously interfere with sexual pleasure and has a failure rate of 25-30%. Vasectomy is safe, effective, and easy to perform, but is not a reversible method. The combination of 20 mg of medroxyprogesterone acetate in 2 daily doses and 100 mg of testosterone applied in an abdominal spray has given very promising results in 2 small studies in France and merits further development and diffusion.

    Paratesticular aggressive angiomyxoma is a very rare tumour in males. Most of documented cases of aggressive angiomyxomas have been seen in genital, perineal and pelvic regions in women of child bearing age. We report two cases of aggressive angiomyxomas in males who presented with inguinal swellings. A globular mass with greyish white, glistening cut surface was received after excision of the mass. Microscopic examination revealed a paucicellular tumour comprising of spindle shaped cells along with vessels of varying calibre. The accompanying stroma was myxocollagenous. In addition there was evidence of fat infiltration in one of the cases. Immunohistochemical staining showed CD34, desmin, vimetin positivity and negative staining for S100, actin, Estrogen Receptors (ER) and Progesterone Receptors (PR). The microscopic and immunohistochemical features favoured the diagnosis of aggressive angiomyxoma. This report of angiomyxoma in two cases of males assumes great significance in view of the extreme rarity of the tumour in males and its locally infiltrative nature.

    The insertion of catheters into male emergency patients is fairly common practice and is associated with a worryingly high rate of infection. Everyday pressures within the department, along with the added stress of resuscitation can result in inappropriately trained or skilled staff undertaking this procedure. The issue of gender and whether female nurses should catheterize male patients may also affect this vulnerable group of patients. Acquiring the psychomotor skills of inserting a urethral catheter is only one part of preparation for practice. Emergency nurses must know when and when not to resort to catheterization. Choosing the type and size of catheter requires careful judgment. What will you do if insertion proves difficult? Prevention of infection is of paramount importance and there are an increasing number of evidence-based sources of information, which are crucial to formulating procedures and informing every day practice. In the pressured surroundings of A&E departments, it is easy to ignore the vulnerability of men requiring catheterization, both from a physical and psychological point of view. Making the effort to explain the procedure, listen to questions and concerns and record relevant details in the notes, will take only a few extra moments. There is no doubt that urinary catheterization is not without complications. It is associated with significant morbidity and occasionally, mortality.

    Background The voluntary medical male circumcision (VMMC) program in Zimbabwe aims to circumcise 80% of males aged 13–29 by 2017. We assessed the impact of actual VMMC scale-up to date and evaluated the impact of potential alterations to the program to enhance program efficiency, through prioritization of subpopulations. Methods and Findings We implemented a recently developed analytical approach: the age-structured mathematical (ASM) model and accompanying three-level conceptual framework to assess the impact of VMMC as an intervention. By September 2014, 364,185 males were circumcised, an initiative that is estimated to avert 40,301 HIV infections by 2025. Through age-group prioritization, the number of VMMCs needed to avert one infection (effectiveness) ranged between ten (20–24 age-group) and 53 (45–49 age-group). The cost per infection averted ranged between $811 (20–24 age-group) and $5,518 (45–49 age-group). By 2025, the largest reductions in HIV incidence rate (up to 27%) were achieved by prioritizing 10–14, 15–19, or 20–24 year old. The greatest program efficiency was achieved by prioritizing 15–24, 15–29, or 15–34 year old. Prioritizing males 13–29 year old was programmatically efficient, but slightly inferior to the 15–24, 15–29, or 15–34 age groups. Through geographic prioritization, effectiveness varied from 9–12 VMMCs per infection averted across provinces. Through risk-group prioritization, effectiveness ranged from one (highest sexual risk-group) to 60 (lowest sexual risk-group) VMMCs per infection averted. Conclusion The current VMMC program plan in Zimbabwe is targeting an efficient and impactful age bracket (13–29 year old), but program efficiency can be improved by prioritizing a subset of males for demand creation and service availability. The greatest program efficiency can be attained by prioritizing young sexually active males and males whose sexual behavior puts them at higher risk for acquiring HIV. PMID

    Male circumcision is a controversial subject in surgical practice. There are, however, clear surgical indications of this procedure. The American Academy of Pediatrics (AAP) recommends newborn male circumcision for its preventive and public health benefits that has been shown to outweigh the risks of newborn male circumcision. Many surgical techniques have been reported. The present review discusses some of these techniques with their merits and drawbacks. This is an attempt to inform the reader on surgical aspects of male circumcision aiding in making appropriate choice of a technique to offer patients. Pubmed search was done with the keywords: Circumcision, technique, complications, and history. Relevant articles on techniques of circumcision were selected for the review. Various methods of circumcision including several devices are in use for male circumcision. These methods can be grouped into three: Shield and clamp, dorsal slit, and excision. The device methods appear favored in the pediatric circumcision while the risk of complications increases with increasing age of the patient at surgery.

  1. [Male contraception].

    1984-04-01

    Among the reasons why male hormonal contraception has lagged behind female methods are the necessity of preserving virility, the fact that spermatogenesis is a continuous process, the need to control secondary effects and toxicity, and the requirement that modes of administration be acceptable to both partners. Among currently available reversible mehtods, withdrawal is undoubtedly the most ancient. It is still widespread but cannot be recommended because of its limited effectiveness. The condom is used by about 10% of couples worldwide as a principal or temporary method, but its inter-ference with sensation has limited its acceptance. Condoms are nevertheless highly effective when used with a spermicide. Various androgens are currently under investigation. High doses of testosterone can induce azoospermia without affecting libido but their side effects may be serious. The use of combinations of steroids permits doses to be reduced and offers promise for the future. The combination of oral medroxyprogesterone acetate and percutaneous testosterone is one of the better approaches; the combination is effective and nontoxic but has the disadvantage of percutaneous administration. Gossypol, a pigment extracted from the cotton plant, has been used as a contraceptive in China with a reported efficacy of 99.89%, recovery of fertility within 3 months, and no effect on future fertility. However, its toxicity appears to be significant in the animal and its reversibility is uncertain. A search is on for analogs which would preserve the contraceptive effects while eliminating toxic effects. Several gonadotropin releasing hormone (GnRH) analogs under investigation for their interference with spermatogenesis have given promising results. Several chemicals tested for contraceptive effects have had unacceptably high toxicity. Chinese investigators have reported good results with various physical methods of interfering with sperm production, but their reversibility and innocuity

    Klippel-Trenaunay syndrome is a rare congenital mesodermal abnormality characterized by bone and soft tissue hypertrophy, extensive hemangioma and venous abnormalities. We report the case of a patient with two additional rare clinical manifestations in the background of Klippel-Trenaunay syndrome, namely, acanthocytosis and splenic and retroperitoneal lymphangioma. A 24-year-old Sri Lankan man from North Central Province in Sri Lanka presented to our general medical unit with symptomatic anaemia. He had been diagnosed with Klippel-Trenaunay syndrome at the age of six years, with hemihypertrophy of his right lower limb and strawberry naevi over both lower limbs. His blood film results were positive for acanthocytes, which accounted for more than 20% of the red blood cell population. He was also found to have extensive splenic lymphangiomas and a large retroperitoneal lymphangioma encasing the mesentric vessels in the right para-aortic region. An extensive battery of tests to identify a secondary cause for the acanthocytosis failed to show any positive results. Retroperitoneal lymphangioma has been reported in association with Klippel-Trenaunay syndrome once before, but an association with acanthocytosis has never been reported. Given the rarity of all three conditions this is not surprising. The cause of acanthocytosis in this setting is currently unresolved. It is plausible that this may be a primary association with Klippel-Trenaunay syndrome, as an alternative aetiology was not found.

    Subareolar abscess of the male breast is a rare condition, which can be complicated by a fistula from the areolar skin into a lactiferous duct. In 1951, Zuska et al first characterised this entity in women. Literature on mammillary fistulas in men is scarce and therefore standardisation of treatment does not exist. We present two cases of recurrent subareolar abscesses with draining fistulas. Both patients were successfully treated by complete excision of the lactiferous duct fistula, and continue to do well with no evidence of disease recurrence. When male patients present with a draining subareolar abscess, one should have a high index of suspicion for a mammillary fistula. Failure to identify and surgically excise the fistula may lead to recurrence of the abscess and prolonged morbidity. The most effective management of this uncommon entity includes complete excision of the lactiferous duct fistula.

    Genetic models of sexual selection are concerned with a dynamic process in which female preference and male trait values coevolve. We present a rigorous method for characterizing evolutionary endpoints of this process in phenotypic terms. In our phenotypic characterization the mate-choice strategy of female population members determines how attractive females should find each male, and a population is evolutionarily stable if population members are actually behaving in this way. This provides a justification of phenotypic explanations of sexual selection and the insights into sexual selection that they provide. Furthermore, the phenotypic approach also has enormous advantages over a genetic approach when computing evolutionarily stable mate-choice strategies, especially when strategies are allowed to be complex time-dependent preference rules. For simplicity and clarity our analysis deals with haploid mate-choice genetics and a male trait that is inherited phenotypically, for example by vertical cultural transmission. The method is, however, easily extendible to other cases. An example illustrates that the sexy son phenomenon can occur when there is phenotypic inheritance of the male trait. PMID:14561306

  8. Male and female mania.

    1986-02-01

    A total of 74 manic or hypomanic episodes were scrutinized in 31 probands (18 women and 13 men), followed over the years by the author on an outpatient basis. These turned out to herald bipolar affective illness in some 70 percent of males and almost 40% of females. Unipolar mania occurred twice as often in men, as it did in women (38.4% vs. 22.2%). Men tended to be younger (only 30% aged 45 or older), than women (almost a half in the menopausal age bracket). One third of all female probands (and over 46% of those under age 45) manifested their manic episodes in connection with childbirth (gestational mania). As a paradoxical, acute grief reaction ("funeral mania"), the syndrome under scrutiny, occurred in about 1/7 of the men, and more than 1/4 of the women. Significant medico-surgical problems were found to accompany or precede female mania twice as often, compared to male cases (61.1% vs. 30.7%); and clinical confusion or other indices of "organicity" were present in 2/3 of the women, and less than a half (46.1%) of the men. Over half the male probands demonstrated either an inverted sexual attraction, or hypogonadism; and four out of 13 males were aged 45 or older. The above findings are tentatively related to gender differential in cerebral hemispheric specialization.

    Male breast cancer (MBC) is a rare disease. However, as global populace ages, there is a trend to MBC increasing. Although aetiology is still unclear, constitutional, environmental, hormonal (abnormalities in estrogen/androgen balance) and genetic (positive family history, Klinefelter syndrome, mutations in BRCA1 and specially BRCA2) risk factors are already known. Clinic manifestation is painless hard and fixed nodule in the subareolar region in 75% of cases, with nipple commitment earlier than in women. Breast cancer has similar prognostic factors in males and females, among which axillary adenopathy (present in 40-55% cases) is the most important one. Although mammography, ultrasonography and scintigraphy can be useful tools in diagnosis; clinical assessment, along with a confirmatory biopsy, remains the main step in the evaluation of men with breast lesions. Infiltrating ductal carcinoma is the most frequent histological type. The established standard of care is modified radical mastectomy followed by tamoxifen for endocrine-responsive positive disease, although other options are being explored. While similarities between breast cancer in males and females exist, it is not appropriate to extrapolate data from female disease to the treatment of male. There is a need for specific multi-institutional trials to better understanding of clinicopathologic features and establishment of optimal therapy for this disease.

    The treatment of paraphilias, especially of pedophilia, centers upon cognitive-behavioral psychotherapy and pharmacologic interventions. Two open, uncontrolled clinical studies using the synthetic LHRH-agonist triptorelin suggested that, combined with psychotherapy, antiandrogen treatment reduced deviant sexual fantasies, urges, and behaviors in paraphilic patients. There is a need for further research using controlled, randomized trials to examine the effectiveness of sexual offender treatment including psychotherapeutic and pharmacologic interventions. The aim of this pilot study is to evaluate the efficacy and tolerability of cognitive-behavioral psychotherapy together with intramuscular (IM) 3-monthly injections of triptorelin in adult men with severe pedophilia. In this multicenter, forensic psychiatric hospital-based, double-blind, controlled, parallel group phase IV trial conducted in Germany, convicted male sexual offenders aged ≥ 18 years with pedophilia, as defined by DSM-IV-TR criteria, will be randomized to receive study-specific psychotherapy together either with triptorelin or placebo for 12 months (total of 4 injections). This is a pilot study, therefore exploratory data analyses will be carried out of three different target parameters: 1. Changes in psychosexual characteristics using the Multiphasic Sex Inventory (scale: sexual abuse of children) 2. Changes in the risk of violent sexual behavior using the Sexual Violence Risk-20 total score 3. Changes in serum testosterone concentration Treatment effects will be assessed by comparing baseline values with those at the final examination (month 12). The absence of real-life stimulants to test for actual recidivism limits possible findings. The study will be conducted in agreement with the European GCP-guideline, all relevant legal requirements, and the legal framework for voluntary treatment of convicted sexual offenders in Germany.

    Osteoporosis in men is a heterogeneous disease that has received little attention. However, one third of worldwide hip fractures occur in the male population. This problem is more prevalent in people over 70 years of age. The etiology can be idiopathic or secondary to hypogonadism, vitamin D deficiency and inadequate calcium intake, hormonal treatments for prostate cancer, use of toxic and every disease or drug use that alters bone metabolism. Risk factors such as a previous history of fragility fracture should be assessed for the diagnosis. However, risk factors in men are very heterogeneous. There are significant differences in the pharmacological treatment of osteoporosis between men and women fundamentally due to the level of evidence in published trials supporting each treatment. New treatments will offer new therapeutic prospects. The goal of this work is a revision of the present status knowledge about male osteoporosis. PMID:23362466

    2014-01-01

    Male Xenopus laevis frogs have been observed to clasp other males in a sustained, amplectant position, the purpose of which is unknown. We examined three possible hypotheses for this counter-intuitive behavior: 1) clasping males fail to discriminate the sex of the frogs they clasp; 2) male-male clasping is an aggressive or dominant behavior; or 3) that males clasp other males to gain proximity to breeding events and possibly engage in sperm competition. Our data, gathered through a series of behavioral experiments in the laboratory, refute the first two hypotheses. We found that males did not clasp indiscriminately, but showed a sex preference, with most males preferentially clasping a female, but a proportion preferentially clasping another male. Males that clasped another male when there was no female present were less likely to "win" reproductive access in a male-male-female triad, indicating that they did not establish dominance through clasping. However, those males did gain proximity to oviposition by continued male-male clasping in the presence of the female. Thus, our findings are consistent with, but cannot confirm, the third hypothesis of male-male clasping as an alternative reproductive tactic.

    Background Countries in sub-Saharan Africa are scaling-up voluntary male medical circumcision (VMMC) as an HIV intervention. Emerging challenges in these programs call for increased focus on program efficiency (optimizing program impact while minimizing cost). A novel analytic approach was developed to determine how subpopulation prioritization can increase program efficiency using an illustrative application for Zambia. Methods and Findings A population-level mathematical model was constructed describing the heterosexual HIV epidemic and impact of VMMC programs (age-structured mathematical (ASM) model). The model stratified the population according to sex, circumcision status, age group, sexual-risk behavior, HIV status, and stage of infection. A three-level conceptual framework was also developed to determine maximum epidemic impact and program efficiency through subpopulation prioritization, based on age, geography, and risk profile. In the baseline scenario, achieving 80% VMMC coverage by 2017 among males 15–49 year old, 12 VMMCs were needed per HIV infection averted (effectiveness). The cost per infection averted (cost-effectiveness) was USD $1,089 and 306,000 infections were averted. Through age-group prioritization, effectiveness ranged from 11 (20–24 age-group) to 36 (45–49 age-group); cost-effectiveness ranged from $888 (20–24 age-group) to $3,300 (45–49 age-group). Circumcising 10–14, 15–19, or 20–24 year old achieved the largest incidence rate reduction; prioritizing 15–24, 15–29, or 15–34 year old achieved the greatest program efficiency. Through geographic prioritization, effectiveness ranged from 9–12. Prioritizing Lusaka achieved the highest effectiveness. Through risk-group prioritization, prioritizing the highest risk group achieved the highest effectiveness, with only one VMMC needed per infection averted; the lowest risk group required 80 times more VMMCs. Conclusion Epidemic impact and efficiency of VMMC programs can be

    Although adolescent males have as many health issues and concerns as adolescent females, they are much less likely to be seen in a clinical setting. This is related to both individual factors and the health care system itself, which is not always encouraging and set up to provide comprehensive male health care. Working with adolescent boys involves gaining the knowledge and skills to address concerns such as puberty and sexuality, substance use, violence, risk-taking behaviours and mental health issues. The ability to engage the young male patient is critical, and the professional must be comfortable in initiating conversation about a wide array of topics with the teen boy, who may be reluctant to discuss his concerns. It is important to take every opportunity with adolescent boys to talk about issues beyond the presenting complain, and let them know about confidential care. The physician can educate teens about the importance of regular checkups, and that they are welcome to contact the physician if they are experiencing any concerns about their health or well-being. Parents of preadolescent and adolescent boys should be educated on the value of regular health maintenance visits for their sons beginning in their early teen years. PMID:19119350

    2003-02-01

    Although endocrinopathies are not often seen in infertile men, these disorders are clinically significant; they often have potentially serious medical significance, regardless of fertility issues. Correction of these disorders represents a possible way to restore normal fertility for the male partner. Male fertility is critically dependent upon a normal hormonal milieu. The hypothalamic-pituitary-gonadal axis is quite sensitive to disruption by endocrine disorders and other generalized medical disorders. Thus, male infertility is occasionally the presenting sign for significant underlying medical disease; it is important to properly evaluate these patients.

    The hypothesis that the preferential rape pattern belongs among the courtship disorders like voyeurism, exhibitionism, and toucheurism was tested. The study consisted of two experiments. The first compared 11 rape-prone males, who were most likely afflicted with the preferential rape pattern, with 11 sexually normal controls on penile response to narratives that depicted scenes in which the individual engaged in behavior typical of voyeurs, exhibitionists, or toucheurs. Narratives depicting normal tactile interaction (short of intercourse) with a genuinely participating woman, normal intercourse, and sexually neutral scenes were also presented. The rape-prone males responded more to the voyeuristic situations than did the controls. The standing of the normal intercourse situations on the scale of erotic value, relative to the other above-mentioned situations, was lower for the rape-prone males than for the normal controls. A second experiment compared 12 rape-prone males, who most likely demonstrated the preferential rape pattern, with 12 males with (other) courtship disorders and 12 sexually normal controls. Penile response to narratives depicting the individual involved in pretactile erotic activity, in tactile sexual activity short of intercourse, or in having intercourse was compared. Each situation was presented in two modalities depicting either a genuinely participating woman or a woman fearful of the individual. The penile responses of the rape-prone males, as well as those of males with other courtship disorders, differentiated less between sexual interaction with a fearful woman and such interaction with a participating woman than did the penile responses of normal controls. There was no significant difference in this respect between the rape-prone males and males with other courtship disorders.

    The present study examined the popular stereotype that gay men lisp by evaluating to what extent listeners associated dental or frontal articulation/lisping with gayness. Fifteen heterosexual males and 15 heterosexual females listened to 275 samples of read speech and judged the sexual orientation of the speakers. A total of 175 of the samples were of homosexual men, 74 (42.3 %) of which had been identified with lisping in a previous study; 100 were of heterosexual men, 18 (18 %) of which had been identified with lisping previously. Based on the ratings of the listeners of the present study, lisping speakers were significantly more often judged to be homosexual. This was true for the group as a whole as well as for the subgroup of homosexual and heterosexual men separately. Furthermore, there was no significant gender difference with respect to associating lisping with gayness. Male and female judges associated lisping with gayness to a similar degree. Additional analysis showed that overall 56.2 % of the time the judges were correct in their judgment of the speakers' sexual orientation. The results of this study confirmed previous preliminary findings that suggested that frontal or dental articulation/lisping is a feature that listeners associate with gayness. The reason for this association remains to be clarified.

    Hypogonadotropic hypogonadism (HH) is common in pituitary stalk interruption (PSI) patients. However, the optimal timing and effective regimen in the management of the pituitary-gonadal axis deficiency is still controversial. This study involved a retrospective review of 38 male patients with HH resulting from PSI. The HH patients were subdivided according to their ages into 2 experiment groups: Group I (adolescents, 14-18 years old, 25 cases) and Group II (young adults, 18-24 years old, 13 cases). To compare the therapeutic response to exogenous gonadotropin, a control analysis was carried out in the experimental groups with age-matched control groups. Before gonadotropin therapy, no significant increases in gonadal hormones were noted in either of the 2 experimental groups. After treatment with human chorionic gonadotropin (hCG) for less than 6 months, the hormone levels of pituitary-gonadal axis significantly increased in group I than in group II. After adding the human menopause gonadotropin (hMG) for 6 months, the gonadal hormone levels of group II were significantly increased. In addition, the Tanner stage and penis lengths in group I were significantly improved. There was no significant adverse impact on BMI and height velocity (HV) after less than one year therapy. A prolonged hypogonadotropic period without treatment may be responsible for testicular dysfunction in HH males caused by PSI. Early supplementary therapy with hCG and hMG is beneficial for the recovery of gonadal hormone and development of secondary sexual characteristics. © Georg Thieme Verlag KG Stuttgart · New York.

  14. Visual perception of male body attractiveness.

    Fan, J; Dai, W; Liu, F; Wu, J

    2005-02-07

    Based on 69 scanned Chinese male subjects and 25 Caucasian male subjects, the present study showed that the volume height index (VHI) is the most important visual cue to male body attractiveness of young Chinese viewers among the many body parameters examined in the study. VHI alone can explain ca. 73% of the variance of male body attractiveness ratings. The effect of VHI can be fitted with two half bell-shaped exponential curves with an optimal VHI at 17.6 l m(-2) and 18.0 l m(-2) for female raters and male raters, respectively. In addition to VHI, other body parameters or ratios can have small, but significant effects on male body attractiveness. Body proportions associated with fitness will enhance male body attractiveness. It was also found that there is an optimal waist-to-hip ratio (WHR) at 0.8 and deviations from this optimal WHR reduce male body attractiveness.

    Objective To review the epidemiology, presentation, diagnosis, molecular genetics, treatment and prognosis of male breast cancer. Data sources Articles, written in English or French, selected from the Medline database (1966 to January 2001), corresponding to the key words “male breast cancer,” according to the following criteria: covering institutional experience or comparing diagnostic and treatment modalities, and epidemiologic or general reviews. Study selection Of 198 articles found 50 fulfilled the review criteria. Data synthesis Risk factors included advanced age, a positive family history, Jewish origin, black race, excess exposure to female hormones (Klinefelter’s syndrome), environmental exposure (irradiation), alcohol, obesity, higher socioeconomic or higher educational status and childlessness. Gynecomastia remains a controversial factor, this term being used for both a histologic reality and a physical finding. Advanced disease is characterized by pain, bloody discharge and skin ulceration. There is no definitive diagnostic algorithm. Experience with male breast mammography is limited, and imaging is less informative for patients under 50 years of age. Fine-needle aspiration tends to overestimate the rate of malignancy. The commonest histologic finding is infiltrating ductal adenocarcinoma. Treatment includes modified radical mastectomy, followed by cyclophosphamide–methotrexate–5-fluo-rouracil or 5-fluorouracil–Adriamycin–cyclophosphamide chemotherapy for disease of stage II or greater. Radiotherapy does not seem to add any benefit. The disease is highly receptor-positive; however, many patients discontinue tamoxifen due to side effects. The most important prognostic factors are tumour size, lymphatic invasion and axillary node status. Conclusions Because of the low incidence of male breast cancer, advances will be obtained mainly with the rapid transfer of newly gained knowledge in female mammary neoplasia. The increased use of adjuvant

    The incidence and mode of presentation of trichomonal urethritis in Nigerian males have benn investigated. Nineteen (10.6%) out of 179 patients presenting with non-gonococcal urethritis were found to harbour the parasite. The commonest symptoms were urethral discharge and/or urethral irritation. The usefulness of examining wet preparations of the urethral exudate in diagnosis is stressed. No significant difference has been found between the incidence of the condition in Nigerians as compared with other ethnic groups. Attention is drawn to the possibility of T. vaginalis playing a role in male infertility, its superinfection in longstanding urethritis is stressed, and the therapeutic efficacy of metronidazole is appraised.

  19. Males adjust their signalling behaviour according to experience of male signals and male-female signal duets.

    PubMed

    Rebar, D; Rodríguez, R L

    2016-04-01

    Sexual signals are conspicuous sources of information about neighbouring competitors, and species in which males and females signal during pair formation provide various sources of public information to which individuals can adjust their behaviour. We performed two experiments with a duetting vibrational insect, Enchenopa binotata treehoppers (Hemiptera: Membracidae), to ask whether males adjust their signalling behaviour according to (1a) their own experience of competitors' signals, (1b) how females adjust their mate preferences on the basis of their experience of male signals (described in prior work), and/or (2) their own experience of female response signals to competitors' signals. We presented males with synthetic male signals of different frequencies and combinations thereof for 2 weeks. We recorded males a day after their last signal exposure, finding that (1a) male signal rate increased in response to experience of attractive competitors, but that (1b) male signal frequency did not shift in a manner consistent with how females adjust their mate preferences in those experience treatments. Second, we presented males with different male-female duets for 2 weeks, finding that (2) male signal length increased from experience of female duets with attractive competitors. Males thus make two types of adjustment according to two sources of public information: one provided by experience of male signals and another by experience of female responses to male signals. Signalling plasticity can generate feedback loops between the adjustments that males and females make, and we discuss the potential consequences of such feedback loops for the evolution of communication systems. © 2016 European Society For Evolutionary Biology.

    Wooldridge, Tom; Lytle, Pauline Polly

    2012-01-01

    This article presents an integrative overview of existing research on anorexia nervosa (AN) in adolescent males. AN is commonly thought of as a female disorder. Even though as much as 25% of the clinical population is male, research on AN in males is limited. Additionally, most conceptualizations of male AN emphasize a single etiological factor and, therefore, produce treatments that fail to address it as a global phenomenon. In contrast, an integrative understanding that incorporates research on the familial, biological, cultural, and psychodynamic elements involved in male AN encourages treatment that comprehensively addresses the disorder.

  2. Why Do Cuckolded Males Provide Paternal Care?

    PubMed Central

    Griffin, Ashleigh S.; Alonzo, Suzanne H.; Cornwallis, Charlie K.

    2013-01-01

    In most species, males do not abandon offspring or reduce paternal care when they are cuckolded by other males. This apparent lack of adjustment of paternal investment with the likelihood of paternity presents a potential challenge to our understanding of what drives selection for paternal care. In a comparative analysis across birds, fish, mammals, and insects we identify key factors that explain why cuckolded males in many species do not reduce paternal care. Specifically, we show that cuckolded males only reduce paternal investment if both the costs of caring are relatively high and there is a high risk of cuckoldry. Under these circumstances, selection is expected to favour males that reduce paternal effort in response to cuckoldry. In many species, however, these conditions are not satisfied and tolerant males have outcompeted males that abandon young. PMID:23555193

    The authors present their experience with the pectoral muscle implant for male chest enhancement in 21 patients. The markings and technique are thoroughly described. The implants used were manufactured and custom made. The candidates for implants comprised three groups: group 1 (18 patients seeking chest enhancement), group 2 (1 patient with muscular atrophy), and group 3 (2 patients with muscular injuries). Because of the satisfying results obtained, including significant enhancement of the chest contour and no major complications, this technique is used for an increasing number of male cosmetic surgeries.

    2013-04-01

    Male genital trauma is a rare but potentially serious sports injury. Although such an injury can occur by many different mechanisms, including falls, collisions, straddle injuries, kicks, and equipment malfunction, the clinical presentation is typically homogeneous, characterized by pain and swelling. Almost all sports-related male genital injury comes from blunt force trauma, with involvement of scrotal structures far more common than penile structures. Most injuries can be treated conservatively, but catastrophic testicular injury must first be ruled out. Despite being relatively uncommon compared with other sports injuries, more than half of all testicular injuries are sustained during sports.

    Two cases of XYY male with refractory anemia with excess of blasts are reported, and previous reported XYY males with hematologic malignancy are reviewed. Altogether 26 cases were collected for analysis: acute myeloid leukemia (10), acute lymphocytic leukemia (seven), acute leukemia (two), chronic myelocytic leukemia (three), myelodysplastic syndrome (three), and essential thrombocythemia (one). The age at the time of diagnosis ranged in age from 7.5 to 81 years. In three of six XYY/XY mosaicism cases, XYY clone was associated with malignancy. However, in two cases XYY clone was not involved. The evidence presented here suggests that the event of an XYY male with hematologic malignancy is incidental rather than a genetic etiology.

    2008-04-01

    Male accessory gland infection (MAGI) is a consequence of canalicular spreading of agents via urethra, prostate gland, seminal vesicles, deferent duct, epididymis and testis. Haematogenous infections are rare. The main infectious agents are Neisseria gonorrhoeae and Chlamydia trachomatis, and also enterobacteriae at a lesser frequency. Characteristic symptoms of MAGI are leukocytospermia, enhanced concentration of cytokines and reactive oxygen species. As complications, obstruction of the ductus epididymidis and/or another duct section, impairment of spermatogenesis in orchitis, impairment of sperm function, and dysfunctions of the male accessory glands may occur. Reduction of male fertility is a rare consequence. The treatment has to consider specific antibiotics.

    The male factor is considered a major contributory factor to infertility. Apart from the conventional causes for male infertility such as varicocoele, cryptorchidism, infections, obstructive lesions, cystic fibrosis, trauma, and tumours, a new and important cause has been identified: oxidative stress. Oxidative stress is a result of the imbalance between reactive oxygen species (ROS) and antioxidants in the body. It is a powerful mechanism that can lead to sperm damage, deformity and eventually, male infertility. This review discusses the physiological need for ROS and their role in normal sperm function. It also highlights the mechanism of production and the pathophysiology of ROS in relation to the male reproductive system and enumerate the benefits of incorporating antioxidants in clinical and experimental settings.

    2009-04-23

    In a recent paper, we demonstrated that male-female genetic relatedness determines male probability of paternity in experimental sperm competition in the Peron's tree frog (Litoria peronii), with a more closely related male outcompeting his rival. Here, we test the hypothesis that a male-male difference in siring success with one female significantly predicts the corresponding difference in siring success with another female. With male sperm concentration held constant, and the proportion of viable sperm controlled statistically, the male-male difference in siring success with one female strongly predicted the corresponding difference in siring success with another female, and alone explained more than 62 per cent of the variance in male-male siring differences. This study demonstrates that male siring success is primarily dictated by among-male differences in innate siring success with less influence of male-female relatedness.

    Male reproduction is governed by the classical hypothalamo-hypophyseal testicular axis: Hypothalamic gonadotropin releasing hormone (GnRH), pituitary luteinizing hormone (LH) and follicle stimulating hormone (FSH) and the gonadal steroid, principally, testosterone. Thyroid hormones have been shown to exert a modulatory influence on this axis and consequently the sexual and spermatogenic function of man. This review will examine the modulatory influence of thyroid hormones on male reproduction. PMID:24701426

  1. Coaching the alpha male.

    PubMed

    Ludeman, Kate; Erlandson, Eddie

    2004-05-01

    Highly intelligent, confident, and successful, alpha males represent about 70% of all senior executives. Natural leaders, they willingly take on levels of responsibility most rational people would find overwhelming. But many of their quintessential strengths can also make alphas difficult to work with. Their self-confidence can appear domineering. Their high expectations can make them excessively critical. Their unemotional style can keep them from inspiring their teams. That's why alphas need coaching to broaden their interpersonal tool kits while preserving their strengths. Drawing from their experience coaching more than 1,000 senior executives, the authors outline an approach tailored specifically for the alpha. Coaches get the alpha's attention by inundating him with data from 360-degree feedback presented in ways he will find compelling--both hard-boiled metrics and vivid verbatim comments from colleagues about his strengths and weaknesses. A 360-degree assessment is a wake-up call for most alphas, providing undeniable proof that their behavior doesn't work nearly as well as they think it does. That paves the way for a genuine commitment to change. In order to change, the alpha must venture into unfamiliar--and often uncomfortable--psychological territory. He must admit vulnerability, accept accountability not just for his own work for others', connect with his underlying emotions, learn to motivate through a balance of criticism and validation, and become aware of unproductive behavior patterns. The goal of executive coaching is not simply to treat the alpha as an individual problem but to improve the entire team dynamic. Initial success creates an incentive to persevere, and the virtuous cycle reverberates throughout the entire organization.

    Study Design. Repeated measures design. Objective. To describe male spine movement and posture characteristics during coitus and compare these characteristics across 5 common coital positions. Summary of Background Data. Exacerbation of pain during coitus due to coital movements and positions is a prevalent issue reported by low back pain patients. A biomechanical analysis of spine movements and postures during coitus has never been conducted. Methods. Ten healthy males and females engaged in coitus in the following preselected positions and variations: QUADRUPED, MISSIONARY, and SIDELYING. An optoelectronic motion capture system was used to measure 3-dimensional lumbar spine angles that were normalized to upright standing. To determine whether each coital position had distinct spine kinematic profiles, separate univariate general linear models, followed by Tukey's honestly significant difference post hoc analysis were used. The presentation of coital positions was randomized. Results. Both variations of QUADRUPED, mQUAD1 and mQUAD2, were found to have a significantly higher cycle speed than mSIDE (P = 0.043 and P = 0.034, respectively), mMISS1 (P = 0.003 and P = 0.002, respectively), and mMISS2 (P = 0.001 and P < 0.001, respectively). Male lumbar spine movement varied depending on the coital position; however, across all positions, the majority of the range of motion used was in flexion. Based on range of motion, the least-to-most recommended positions for a male flexion-intolerant patient are mSIDE, mMISS2, mQUAD2, mMISS1, and mQUAD1. Conclusion. Initial recommendations—which include specific coital positions to avoid, movement strategies, and role of the partner—were developed for male patients whose low back pain is exacerbated by specific motions and postures.

  3. Male-male homosexology: seven short discourses.

    PubMed

    Money, John

    2004-09-01

    Homosexology is that branch of the science of sexology that deals with same sex relationships. It is subdivided into ideation, imagery, and praxis. Praxeology is the science of praxis. There are two doctrines by which homosexuality is defined: elective and developmental. Elective is like joining a political party and is more likely bisexual than exclusively homosexual. Complete developmental homosexuality is a state of being and is characteristically immutable. Both types of homosexuality are determined multivariately and sequentially, not univariately. Male and female mammals are phylogenically programmed to be reciprocal, not identical, in the praxeology of their courtship and mating. In primate, notably human, evolution, the eyes have taken over from the nose as organs of erotic arousal, but the molecular biology of how this happens in individual development, gay, straight or ambivalent, remains to be ascertained. The different personal histories of homosexual development also remain to be ascertained and cataloged.

    2014-12-01

    In sexually reproducing animals, male and female reproductive strategies often conflict. In some species, males use aggression to overcome female choice, but debate persists over the extent to which this strategy is successful. Previous studies of male aggression toward females among wild chimpanzees have yielded contradictory results about the relationship between aggression and mating behavior. Critically, however, copulation frequency in primates is not always predictive of reproductive success. We analyzed a 17-year sample of behavioral and genetic data from the Kasekela chimpanzee (Pan troglodytes schweinfurthii) community in Gombe National Park, Tanzania, to test the hypothesis that male aggression toward females increases male reproductive success. We examined the effect of male aggression toward females during ovarian cycling, including periods when the females were sexually receptive (swollen) and periods when they were not. We found that, after controlling for confounding factors, male aggression during a female's swollen periods was positively correlated with copulation frequency. However, aggression toward swollen females was not predictive of paternity. Instead, aggression by high-ranking males toward females during their nonswollen periods was positively associated with likelihood of paternity. This indicates that long-term patterns of intimidation allow high-ranking males to increase their reproductive success, supporting the sexual coercion hypothesis. To our knowledge, this is the first study to present genetic evidence of sexual coercion as an adaptive strategy in a social mammal.

We manipulated both the activity and sex of a subset of neurons and found significant changes in male social behavior. Results from aggression assays indicate that the neuromodulator octopamine (OCT) is necessary for Drosophila males to coordinate sensory cue information presented by a second male and respond with the appropriate behavior: aggression rather than courtship. In competitive male courtship assays, males with no OCT or with low OCT levels do not adapt to changing sensory cues and court both males and females. We identified a small subset of neurons in the suboesophageal ganglion region of the adult male brain that coexpress OCT and male forms of the neural sex determination factor, Fruitless (FruM). A single FruM-positive OCT neuron sends extensive bilateral arborizations to the suboesophageal ganglion, the lateral accessory lobe, and possibly the posterior antennal lobe, suggesting a mechanism for integrating multiple sensory modalities. Furthermore, eliminating the expression of FruM by transformer expression in OCT/tyramine neurons changes the aggression versus courtship response behavior. These results provide insight into how complex social behaviors are coordinated in the nervous system and suggest a role for neuromodulators in the functioning of male-specific circuitry relating to behavioral choice.

    The present study demonstrates the incidence of high lethality of F1 (Dh/+) male mice, the offspring of DDD females and inbred DH (Dh/+) males. Among the newborn pups, the numbers of F1 (Dh/+) males are comparable to those of mice having other genotypes (+/+ male, Dh/+ female and +/+ female), but many F1 (Dh/+) males died before weaning. On the other hand, among the F1 mice from the cross between DH (Dh/+) females and DDD males, there are no biased numbers of Dh genotype pups. These results suggest the existence of defects in the interaction between the male derived Dh gene and the genetic traits of the DDD female.

    We recently investigated two patients with diabetes and elevated serum prolactin levels in whom no cause of hyperprolactinaemia could be found. For this reason we measured fasting serum prolactin levels in 72 diabetic males and compared the results with those of 63 healthy males and 90 nondiabetic males attending an Impotence Clinic. The diabetic group had significantly higher serum prolactin levels (13.1 +/- 0.9 ng/ml) than the two control groups (9.9 +/- 0.6 ng/ml for normal males and 7.7 +/- 0.3 ng/ml for the non-diabetic impotent group). Eighteen percent of the diabetics studied had serum prolactin levels above the normal range for males (greater than 20 ng/ml). There was no correlation between serum prolactin levels and duration of diabetes, glycosylated haemoglobin level or presence of clinically apparent retinopathy. The correlation between serum prolactin level and fasting plasma glucose was weak though statistically significant (r = 0.26, P less than 0.05). PMID:3991396

  8. Male breast cancer: a review

    Male breast cancer (MBC) is rare, with the peak age of onset at 71 years. BRCA2 mutations are more frequent than BRCA1 with 20% of cases giving a family history. Risk factors for MBC are poorly understood and include working in high-ambient temperatures and exhaust fume exposure. MBC is associated with hyperoestrogenic states found in liver disease, Klinefelter’s syndrome, gonadal dysfunction or obesity. Most information on treatment of MBC is derived from large randomized trials carried out in female patients. The small numbers of MBC seen in any unit annually has precluded significant trials being carried out. Diagnosis and treatment of MBC is similar to that of female patients, but men tend to be treated with mastectomy rather than breast-conserving surgery. The mainstay of adjuvant therapy or palliative treatment for advanced disease is endocrine, mostly tamoxifen. Prognosis of male patients is equal to that of stage-matched women, but men tend to fare worse because of delay in presentation, leading to a large proportion of patients presenting with stage III or IV disease. Increased input is needed for psychological support for male breast cancer patients. Specific therapeutic questions about MBC need international trials to obtain meaningful answers. PMID:22276005

    2008-01-01

    Eating disorders may affect some athletes at rates much greater than the general population. Among male athletes, eating disorders are on the rise. Studies show that males participating in sports in which leanness confers a competitive advantage may be at greater risk of eating disorders. No studies have shown that it is possible to prevent eating disorders in at-risk populations. Once present, eating disorders can be challenging to treat. Psychotherapy and medications have been shown to be helpful. A team approach to the treatment of eating disorders should be used, including regular interaction with a dietician, a mental health professional, a team physician, and other professionals as needed. To maintain participation, athletes must partner with the health care team in their treatment, maintain a healthy weight, and be clear in the understanding that their health is a greater priority than their sport.

    While 7 % of the men are infertile, currently, a genetic etiology is identified in less than 25 % of those men, and 30 % of the infertile men lack a definitive diagnosis, falling in the "idiopathic infertility" category. Advances in genetics and epigenetics have led to several proposed mechanisms for male infertility. These advances may result in new diagnostic tools, treatment approaches, and better counseling with regard to treatment options and prognosis. In this review, we focus on clinical aspects of male infertility and the role of genetics in elucidating etiologies and the potential of treatments.

  15. Male homosexuality reconsidered.

    PubMed

    Leavy, S A

    Prevailing psychoanalytic attitudes toward male homosexuality are predisposed to the treatment of it as a psychopathological disorder. This study proposes that the appearance of disorder follows from the distortions imposed on the personality during development. Superego conflicts ensue that are relieved rather than resolved in the analysis, if the analyst shares the patient's conviction that it is sexuality that is disordered. The study's second point is the suggestion that the unifying characteristic of male homosexuals is to be found in the particular form of body narcissism that leads to same-sex choice. Third, it is proposed that analysts reconsider the likelihood that biogenetic elements enter into the homosexual outcome.

    Male breast cancer (MBC) is a rare disease, accounting for less than 1% of all breast cancer diagnoses worldwide. Although breast carcinomas share certain characteristics in both genders, there are notable differences. Most studies on men with breast cancer are very small. Thus, most data on male breast cancer are derived from studies on females. However, when a number of these small studies are grouped together, we can learn more from them. This review emphasizes the incidence, etiology, clinical features, diagnosis, treatment, pathology, survival, and prognostic factors related to MBC.

  19. Male rat sexual behavior.

    PubMed

    Agmo, A

    1997-05-01

    The male rat's sexual behavior constitutes a highly ordered sequence of motor acts involving both striate and smooth muscles. It is spontaneously displayed by most adult made rats in the presence of a sexually receptive female. Although the behavior is important for the survival of the species it is not necessary for survival of the individual. In that way it is different from other spontaneous behaviors such as eating, drinking, avoidance of pain, respiration or thermoregulation. Among other things, this means that it is difficult to talk about sexual deprivation or need. Nevertheless, studies of male sex behavior distinguish sexual motivation (the ease by which behavior is activated, "libido") from the execution of copulatory acts (performance, "potency") (Meisel, R.L. and Sachs, B.D., The physiology of male sexual behavior. In: E. Knobil and J.D. Neill (Eds.), The Physiology of Reproduction, 2nd Edn., Vol. 2, Raven Press, New York, 1994, pp. 3-105 [13]). The hormonal control of male sexual behavior has been extensively studied. It is clear that steroid hormones, androgens and estrogens, act within the central nervous system, modifying neuronal excitability. The exact mechanism by which these hormones activate sex behavior remains largely unknown. However, there exists a considerable amount of knowledge concerning the brain structures important for sexual motivation and for the execution of sex behavior. The modulatory role of some non-steroid hormones is partly known, as well as the consequences of manipulations of several neurotransmitter systems.

  1. Lycopene and male infertility

    PubMed Central

    Durairajanayagam, Damayanthi; Agarwal, Ashok; Ong, Chloe; Prashast, Pallavi

    2014-01-01

    Excessive amounts of reactive oxygen species (ROS) cause a state of oxidative stress, which result in sperm membrane lipid peroxidation, DNA damage and apoptosis, leading to decreased sperm viability and motility. Elevated levels of ROS are a major cause of idiopathic male factor infertility, which is an increasingly common problem today. Lycopene, the most potent singlet oxygen quencher of all carotenoids, is a possible treatment option for male infertility because of its antioxidant properties. By reacting with and neutralizing free radicals, lycopene could reduce the incidence of oxidative stress and thus, lessen the damage that would otherwise be inflicted on spermatozoa. It is postulated that lycopene may have other beneficial effects via nonoxidative mechanisms in the testis, such as gap junction communication, modulation of gene expression, regulation of the cell cycle and immunoenhancement. Various lycopene supplementation studies conducted on both humans and animals have shown promising results in alleviating male infertility—lipid peroxidation and DNA damage were decreased, while sperm count and viability, and general immunity were increased. Improvement of these parameters indicates a reduction in oxidative stress, and thus the spermatozoa is less vulnerable to oxidative damage, which increases the chances of a normal sperm fertilizing the egg. Human trials have reported improvement in sperm parameters and pregnancy rates with supplementation of 4–8 mg of lycopene daily for 3–12 months. However, further detailed and extensive research is still required to determine the dosage and the usefulness of lycopene as a treatment for male infertility. PMID:24675655

    2014-02-01

    Male breast carcinoma is an uncommon neoplasm, accounting for 0.6% of all breast carcinomas. Invasive ductal carcinoma of no special type is the most common type of male breast carcinoma, and mucinous carcinoma occurring in the male breast is extremely rare. In the present study, we report a case of mucinous carcinoma of the male breast and discuss the clinicopathological features of this type of tumor. A 63-year-old Japanese male presented with a gradually enlarged nodule in the right breast. The resected breast specimen revealed pure mucinous carcinoma and immunohistochemical analyses demonstrated that tumor cells were positive for estrogen receptor (ER), but negative for progesterone receptor (PgR). In addition, HER2 expression was not amplified. Pure mucinous carcinoma is generally associated with a low incidence of lymph node or distant metastases, and excellent disease-free survival in females. However, certain cases of this type of tumor with axillary lymph node metastasis in the male breast have been reported. In addition, the immunoprofiles of mucinous carcinoma in males are fundamentally the same as those in females. More than 90% of cases show positive immunoreactivity for ER and/or PgR, and HER2 expression is not amplified. However, it has been reported that breast cancer in males is more frequently positive for ER than in females, and has less HER2 overexpression. The high rate of hormone receptor-positive breast cancer in males is considered to be due to similar conditions as those in breast cancer in postmenopausal women. The pathogenesis of male breast carcinoma, including mucinous carcinoma, remains unclear; therefore, additional clinicopathological studies are required.

  8. Epigenetics, spermatogenesis and male infertility.

    2011-01-01

    Epigenetic modifications characterized by DNA methylation, histone modifications, and chromatin remodeling are important regulators in a number of biological processes, including spermatogenesis. Several genes in the testes are regulated through epigenetic mechanisms, indicating a direct influence of epigenetic mechanisms on the process of spermatogenesis. In the present article, we have provided a comprehensive review of the epigenetic processes in the testes, correlation of epigenetic aberrations with male infertility, impact of environmental factors on the epigenome and male fertility, and significance of epigenetic changes/aberrations in assisted reproduction. The literature review suggested a significant impact of epigenetic aberrations (epimutations) on spermatogenesis, and this could lead to male infertility. Epimutations (often hypermethylation) in several genes, namely MTHFR, PAX8, NTF3, SFN, HRAS, JHM2DA, IGF2, H19, RASGRF1, GTL2, PLAG1, D1RAS3, MEST, KCNQ1, LIT1, and SNRPN, have been reported in association with poor semen parameters or male infertility. Environmental toxins/drugs may affect fertility via epigenetic modifications. For example, 5-aza-2'-deoxycytidine, an anticancer agent, causes a decrease in global DNA methylation that leads to altered sperm morphology, decreased sperm motility, decreased fertilization capacity, and decreased embryo survival. Similarly, Endocrine disruptors, such as methoxychlor (an estrogenic pesticide) and vinclozolin (an anti-androgenic fungicide) have been found by experiments on animals to affect epigenetic modifications that may cause spermatogenic defects in subsequent generations. Assisted reproduction procedures that have been considered rather safe, are now being implicated in inducing epigenetic changes that could affect fertility in subsequent generations. Techniques such as intracytoplasmic sperm injection (ICSI) and round spermatid injection (ROSI) may increase the incidence of imprinting disorders and

  10. Is male rhesus macaque red color ornamentation attractive to females?

    PubMed Central

    Dubuc, Constance; Allen, William L.; Maestripieri, Dario; Higham, James P.

    2014-01-01

    Male sexually-selected traits can evolve through different mechanisms: conspicuous and colorful ornaments usually evolve through inter-sexual selection, while weapons usually evolve through intra-sexual selection. Male ornaments are rare among mammals in comparison to birds, leading to the notion that female mate choice generally plays little role in trait evolution in this taxon. Supporting this view, when ornaments are present in mammals they typically indicate social status and are products of male-male competition. This general mammalian pattern, however, may not apply to rhesus macaques (Macaca mulatta). Males of this species display conspicuous skin coloration, but this expression is not correlated to dominance rank, and is therefore unlikely to have evolved due to male-male competition. Here, we investigate whether male color expression influences female proceptivity towards males in the Cayo Santiago free-ranging rhesus macaque population. We collected face images of 24 adult males varying in dominance rank and age at the peak of the mating season, and modeled these to rhesus macaque visual perception. We also recorded female socio-sexual behaviors towards these males. Results show that dark red males received more sexual solicitations, by more females, than pale pink ones. Together with previous results, our study suggests that male color ornaments are more likely to be a product of inter- rather than intra-sexual selection. This may especially be the case in rhesus macaques due to the particular characteristics of male-male competition in this species. PMID:25246728

    Polychlorinated biphenyls (PCBs) are a class of persistent organic pollutants with estrogen-like effects that exist widely in the environment, and its male reproductive toxicity is arousing more and more attention. Studies indicate that different types of cells in the testis respond differently to PCBs exposure. This article presents an overview on the toxicity of PCBs to testicular germ cells, Leydig cells, Sertoli cells and male offspring. We suggest that deeper studies focus on the mechanism of PCBs according to the results of investigations on male reproductive epidemiology. An insight into the intercellular junctions of Sertoli cells might produce a breakthrough in the studies of the testicular toxicity of PCBs.

    There has been a significant surge in aesthetic chest surgery for men in the last several years. Male chest enhancement is performed with surgical placement of a solid silicone pectoral implant. In the past, male chest correction and implantation were limited to the treatment of men who had congenital absence or atrophy of the pectoralis muscle and pectus excavatum deformity. But today, the popularization of increased chest and pectoral size fostered by body builders has more men desiring chest correction with implantation for non-medical reasons. We present a case of a 44-year-old, male with a displaced left pectoral implant with near extrusion and with an associated peri-implant soft tissue mass and fluid collection. While the imaging of these patients is uncommon, our case study presents the radiographic findings of male chest enhancement with associated complications. PMID:27200162

    Male genital lichen sclerosus (MGLSc) is a chronic inflammatory skin disease responsible for male sexual dyspareunia and urological morbidity. An afeared complication is squamous cell carcinoma (SCC) of the penis. The precise etiopathogenesis of MGLSc remains controversial although genetic, autoimmune and infective (such as human papillomavirus (HPV) hepatitis C (HCV), Epstein-Barr virus (EBV) and Borrelia) factors have been implicated: Consideration of all the evidence suggests that chronic exposure of susceptible epithelium to urinary occlusion by the foreskin seems the most likely pathomechanism. The mainstay of treatment is topical ultrapotent corticosteroid therapy. Surgery is indicated for cases unresponsive to topical corticosteroid therapy, phimosis, meatal stenosis, urethral stricture, carcinoma in situ (CIS) and squamous cell carcinoma. PMID:25814697

    Despite significant advances in contraceptive options for women over the last 50 yr, world population continues to grow rapidly. Scientists and activists alike point to the devastating environmental impacts that population pressures have caused, including global warming from the developed world and hunger and disease in less developed areas. Moreover, almost half of all pregnancies are still unwanted or unplanned. Clearly, there is a need for expanded, reversible, contraceptive options. Multicultural surveys demonstrate the willingness of men to participate in contraception and their female partners to trust them to do so. Notwithstanding their paucity of options, male methods including vasectomy and condoms account for almost one third of contraceptive use in the United States and other countries. Recent international clinical research efforts have demonstrated high efficacy rates (90–95%) for hormonally based male contraceptives. Current barriers to expanded use include limited delivery methods and perceived regulatory obstacles, which stymie introduction to the marketplace. However, advances in oral and injectable androgen delivery are cause for optimism that these hurdles may be overcome. Nonhormonal methods, such as compounds that target sperm motility, are attractive in their theoretical promise of specificity for the reproductive tract. Gene and protein array technologies continue to identify potential targets for this approach. Such nonhormonal agents will likely reach clinical trials in the near future. Great strides have been made in understanding male reproductive physiology; the combined efforts of scientists, clinicians, industry and governmental funding agencies could make an effective, reversible, male contraceptive an option for family planning over the next decade.

  20. Melatonin and male reproduction.

    PubMed

    Li, Chunjin; Zhou, Xu

    2015-06-15

    Melatonin is a neurohormone secreted by the pineal gland whose concentrations in the body are regulated by both the dark-light and seasonal cycles. The reproductive function of seasonal breeding animals is clearly influenced by the circadian variation in melatonin levels. Moreover, a growing body of evidence indicates that melatonin has important effects in the reproduction of some non-seasonal breeding animals. In males, melatonin affects reproductive regulation in three main ways. First, it regulates the secretion of two key neurohormones, GnRH and LH. Second, it regulates testosterone synthesis and testicular maturation. Third, as a potent free radical scavenger that is both lipophilic and hydrophilic, it prevents testicular damage caused by environmental toxins or inflammation. This review summarizes the existing data on the possible biological roles of melatonin in male reproduction. Overall, the literature data indicate that melatonin affects the secretion of both gonadotropins and testosterone while also improving sperm quality. This implies that it has important effects on the regulation of testicular development and male reproduction.

    Systemic lupus erythematosus (SLE) is more common among women than men with a ratio of about 10 to 1. We undertook this study to describe familial male SLE within a large cohort of familial SLE. SLE families (two or more patients) were obtained from the Lupus Multiplex Registry and Repository. Genomic DNA and blood samples were obtained using standard methods. Autoantibodies were determined by multiple methods. Medical records were abstracted for SLE clinical data. Fluorescent in situ hybridization (FISH) was performed with X and Y centromere specific probes, and a probe specific for the toll-like receptor 7 gene on the X chromosome. Among 523 SLE families, we found five families in which all the SLE patients were male. FISH found no yaa gene equivalent in these families. SLE-unaffected primary female relatives from the five families with only-male SLE patients had a statistically increased rate of positive ANA compared to SLE-unaffected female relatives in other families. White men with SLE were 5 times more likely to have an offspring with SLE than were White women with SLE but there was no difference in this likelihood among Black men. These data suggest genetic susceptibility factors that act only in men. PMID:20472921

Understanding factors that influence detection probabilities will allow managers to more accurately estimate the number of males present on leks.

    Although the use of formant frequencies in nonhuman animal vocal communication systems has received considerable recent interest, only a few studies have examined the importance of these acoustic cues to body size during intra-sexual competition between males. Here we used playback experiments to present free-ranging male koalas with re-synthesised bellow vocalisations in which the formants were shifted to simulate either a large or a small adult male. We found that male looking responses did not differ according to the size variant condition played back. In contrast, male koalas produced longer bellows and spent more time bellowing when they were presented with playbacks simulating larger rivals. In addition, males were significantly slower to respond to this class of playback stimuli than they were to bellows simulating small males. Our results indicate that male koalas invest more effort into their vocal responses when they are presented with bellows that have lower formants indicative of larger rivals, but also show that males are slower to engage in vocal exchanges with larger males that represent more dangerous rivals. By demonstrating that male koalas use formants to assess rivals during the breeding season we have provided evidence that male-male competition constitutes an important selection pressure for broadcasting and attending to size-related formant information in this species. Further empirical studies should investigate the extent to which the use of formants during intra-sexual competition is widespread throughout mammals. PMID:23922967

    Varicoceles are the most common cause of male infertility. They afflict 15–20% of the general male population and 40% of males with primary infertility. Although multiple treatment modalities exist, including radiographic embolization and laparoscopy, open subinguinal microsurgical varicocelectomy is currently the gold standard of treatment for this condition. In this article, we discuss the role of varicocelectomy in the treatment of the modern infertile male and present a practical, safe, and reproducible technique for the microsurgical approach.

    Several lines of evidence indicate the existence of genetic factors influencing male homosexuality and bisexuality. In spite of its relatively low frequency, the stable permanence in all human populations of this apparently detrimental trait constitutes a puzzling ‘Darwinian paradox’. Furthermore, several studies have pointed out relevant asymmetries in the distribution of both male homosexuality and of female fecundity in the parental lines of homosexual vs. heterosexual males. A number of hypotheses have attempted to give an evolutionary explanation for the long-standing persistence of this trait, and for its asymmetric distribution in family lines; however a satisfactory understanding of the population genetics of male homosexuality is lacking at present. We perform a systematic mathematical analysis of the propagation and equilibrium of the putative genetic factors for male homosexuality in the population, based on the selection equation for one or two diallelic loci and Bayesian statistics for pedigree investigation. We show that only the two-locus genetic model with at least one locus on the X chromosome, and in which gene expression is sexually antagonistic (increasing female fitness but decreasing male fitness), accounts for all known empirical data. Our results help clarify the basic evolutionary dynamics of male homosexuality, establishing this as a clearly ascertained sexually antagonistic human trait. PMID:18560521

    Technological change, particularly the growth of the Internet and smart phones, has increased the visibility of male escorts, expanded their client base and diversified the range of venues in which male sex work can take place. Specifically, the Internet has relocated some forms of male sex work away from the street and thereby increased market reach, visibility and access and the scope of sex work advertising. Using the online profiles of 257 male sex workers drawn from six of the largest websites advertising male sexual services in Australia, the role of the Internet in facilitating the normalisation of male sex work is discussed. Specifically we examine how engagement with the sex industry has been reconstituted in term of better informed consumer-seller decisions for both clients and sex workers. Rather than being seen as a 'deviant' activity, understood in terms of pathology or criminal activity, male sex work is increasingly presented as an everyday commodity in the market place. In this context, the management of risks associated with sex work has shifted from formalised social control to more informal practices conducted among online communities of clients and sex workers. We discuss the implications for health, legal and welfare responses within an empowerment paradigm.

    1980-01-01

    Although hair dyes have been shown to be highly mutagenic the literature on possible human cancer risk is confused. A variety of studies using different methods in different countries have provided a range of positive and negative findings. In the present study the observed and expected mortality among a sample of hairdressers identified in the 1961 census was examined and followed until 1978; attention was focused on five malignancies reported to have increased in male hairdressers in the other studies. The overall mortality and number of deaths from all neoplasms were lower than the 'expected' figures. No appreciable or significant excess was found for cancer of the oesophagus, larynx, lung, and bladder, or for leukaemia. The present report, based on the follow-up of nearly 2000 hairdressers for more than 15 years, provides no support for other work which has suggested that male hairdressers or barbers are at risk of certain cancers. These results provide only a limited probe into the influence of hair dyes; another part of the study involves follow-up of women hairdressers from the 1971 census, though it will be a number of years before enough deaths have accumulated to warrant analysis.

  10. Genetic aspects of communication during male-male competition in the Madagascar hissing cockroach: honest signalling of size.

    PubMed

    1995-08-01

    Male Madagascar hissing cockroaches, Gromphadorhina portentosa, engage in agonistic contests with other males and produce audible sounds or 'hisses' during these interactions. Hisses are used to maintain, rather than to establish, social relationships among males. The agonistic hisses of males are variable and could be used as signals to communicate size or competitive ability of an individual. In this study we examined how size influences male-male competition, as well as the genetic variation and covariation of male body size and components of the agonistic hiss. We found that male size affected the outcome of agonistic interactions between pairs of males: a male that dominated in a pair was significantly larger than the male that was subordinate. However, we found no differences in the hisses produced by dominant and subordinate males after controlling for male weight. We estimated heritabilities, evolvability and genetic correlations for male size and characteristics of the hiss from a full-sib analysis of brothers. The patterns of heritabilities and evolvabilities were very similar. The heritabilities of both male weight and duration of the hiss were significantly greater than zero. There was a significant positive genetic correlation between duration of the agonistic hiss and male weight, and a significant negative genetic correlation between hiss duration and the beginning dominant frequency. There was also a positive phenotypic correlation and a negative environmental correlation between male weight and hiss duration. Thus, hiss duration can signal the present influence of the environment on male size, whereas information from hiss duration and beginning dominant frequency can signal the male's ability to transmit genetic influence for size.(ABSTRACT TRUNCATED AT 250 WORDS)

We present his clinical course and outcome and briefly discuss the mechanism of injury and otologic barotrauma. Roller coasters have been reported as the cause of many different types of injuries, but this is the first reported case of otologic barotrauma. As the engineering for roller coasters continues to advance in terms of increasing speed, otolaryngologists need to be aware of a new etiology of otologic barotrauma.

    Concerning one case of male urethral diverticulum, the characteristics of this rare affection are reviewed. Carriage for long time of urethral catheter and urethroplasty are the more frequent etiologies of this affection. The diagnosis is clinic, based on the discovery of tumefaction on the urethral track which pression makes spring up urine through urethral meatus. The urethrography confirms the diagnosis. Surgical approach consists on the resection of the diverticulum and urethrorrhaphy in one or two stages, based on diverticular neck size and sheet quality.

    Out pouching of the urethral wall could be congenital or acquired. Male urethral diverticulum (UD) is a rare entity. We present 2 cases of acquired and 1 case of congenital male UD. Case 1A: 40 year male presented with SPC and dribbling urine. Clinically he had hard perineal swelling. RGU revealed large diverticulum in proximal bulbar, irregular narrow distal urethra and stricture just beyond diverticulum. Managed with perineal exploration, stone removal, diverticulum repair and urethroplasty using excess diverticular wall. Case 2A: 30 year male with obstructive lower urinary tract symptoms (LUTS). Retrograde urethrogram (RGU) revealed bulbar urethral diverticulum akin to anterior urethral valve, managed endoscopically. 1 year follow up urine stream satisfactory. Case 3A: 27 year male previously operated large proximal bulbar urethral stone with incontinence. RGU large proximal bulbar UD with wide open sphincter. Treated with excision of excess diverticular wall and penile clamp with pelvic exercises for incontinence. Congenital UD develops due to imperfect closure of urethral fold, Acquired UDs occurs secondary to stricture, infection, trauma, long standing impacted urethral stones or scrotal / skin flap urethroplasties. RGU and MCU are the best diagnostic technique to confirm and characterize the UD. Urethral diverticulectomy with urethral reconstruction is the recommended treatment for UD. UD is a rare entity. Especially in males, congenital are even more rare. Management should be individualized. Surgery can involve innovation and/or surgical modifications. We used excess diverticular flap for stricture urethroplasty in one case. PMID:28057997

    Infertility is a significant problem for human reproduction, with males and females equally affected. However, the molecular mechanisms underlying male infertility remain unclear. Spermatogenesis is a highly complex process involving mitotic cell division, meiosis cell division and spermiogenesis; during this period, unique and extensive chromatin and epigenetic modifications occur to bring about specific epigenetic profiles in spermatozoa. It has recently been suggested that the dysregulation of epigenetic modifications, in particular the methylation of sperm genomic DNA, may serve an important role in the development of numerous diseases. The present study is a comprehensive review on the topic of male infertility, aiming to elucidate the association between sperm genomic DNA methylation and poor semen quality in male infertility. In addition, the current status of the genetic and epigenetic determinants of spermatogenesis in humans is discussed. PMID:27698683

    On 68 selected patients with disturbances of the potentia generandi et/sive coeundi (25 males with healthy metabolism and 43 males with diabetes) as well as 14 control persons PRL, LH, FSH, testosterone and oestradiol were determined radioimmunologically and the results were ascribed to sexological, clinical, spermatological and testo-histological findings. A statistically secure correlation was found between PRL values and disturbance of the libido as well as the presence of a gynaecomasty. PRL did not correlate with the spermatological variables volume of ejaculate, relative and absolute number of spermatozoa and motility. PRL did also not correlate with the testohistological findings. A relation between PRL and the peptide hormones LH and FSH as well as the steroid hormones testosterone and oestradiol could not be ascertained. Therefore the diagnostic values of a PRL determination is much limited; the pertinency of a hyperprolactinaemia may be increased by the proof of the symptoms reduction of libido and gynaecomasty with simultaneous disturbance of fertility. In our opinion the definition of hyperprolactinaemia needs revision, since at only determination of the basal value of more than 800 mU/l no more frequently pathologically andrological findings are to be observed than below 200 mU/l.

    Infections and inflammations of the genital tract are considered the most frequent causes of reduced male fertility, but conclusive epidemiological data are not available. In view of the exposure of germ cells to pathogenic components as well as the cells and mediators involved in the inflammatory processes, irreversible damage to spermatogenesis and corresponding decline of ejaculate quality are to be expected, particularly in cases of chronic orchitis. While the consequences of orchitis and epididymo-orchitis that exhibit clinical symptoms due to systemic or local infections are well known, including testicular atrophy and complete loss of fertility, those cases of inflammatory reactions of the testicles that manifest an asymptomatic or subclinical course, or are not even due to an infection, have received little attention until now. However, systematic histopathological analyses have shown a high prevalence of asymptomatic inflammatory reactions in testicular biopsies from infertile men. The mostly focal lymphocytic infiltrates correlate with the degree of damage to spermatogenesis and corresponding clinical and endocrinological parameters of testicular function. Noninvasive diagnostic techniques are not yet available so that chronic asymptomatic inflammations of the testicles as the primary cause or cofactor of male fertility disorders are underestimated. Except for administration of pathogen-specific antibiotics, treatment recommendations are to a large extent still lacking.

  18. Male hormonal contraceptives.

    PubMed

    Amory, J K

    2006-06-01

    Efforts are underway to develop additional forms of contraception for men. The most promising approach to male contraceptive development involves the administration of exogenous testosterone (T). When administered to a man, T functions as a contraceptive by suppressing the secretion of luteinizing hormone and follicle-stimulating hormone from the pituitary, thereby depriving the testes of the signals required for spermatogenesis. After 2-3 months of treatment, low levels of these gonadotropins lead to markedly decreased sperm counts and effective contraception in a majority of men. Hormonal contraception with exogenous T has proven to be free from serious adverse effects and is well tolerated by men. In addition, sperm counts uniformly normalize when the exogenous T is discontinued. Thus, male hormonal is safe, effective and reversible; however, spermatogenesis is not suppressed to zero in all men, meaning that some diminished potential for fertility persists. Because of this recent studies have combined T with progestogens and/or gonadotropin-releasing antagonists to further suppress pituitary gonadotropins and optimize contraceptive efficacy. Current combinations of T and progestogens completely suppress spermatogenesis without severe side effects in 80-90% of men, with significant suppression in the remainder of individuals. Recent trials with newer, long-acting forms of injectable T, which can be administered every 8 weeks, combined with progestogens, administered either orally or by long-acting implant, have yielded promising results and may soon result in the marketing of a safe, reversible and effective hormonal contraceptive for men.

    This study examined victim and assault characteristics and the nature and extent of coercion, violence, and physical injuries among adult male victims of sexual assaults. Client records of three groups presenting to a sexual assault care center were included: males assaulted by a stranger (n = 64), males assaulted by an acquaintance (n = 81), and females assaulted by an acquaintance (n = 106). Study results revealed that male victims of sexual assault tended to be young, single men who reported high rates of vulnerabilities such as homelessness and physical, psychiatric, and cognitive disabilities. Male stranger assailant victims were more likely to experience assaults involving weapons and physical violence. Injuries sustained by victims and services delivered at the sexual assault care center were similar for both male and female clients. The results of this study reveal new information about violence in male sexual assaults and the vulnerability of the male victims.

    Forty-two male patients with an anorexic syndrome were assessed personally (n = 29) or by reviewing the case-notes. Twenty-nine male patients were classified as primary anorexia nervosa and they were compared to our series of atypical male patients and a series of 23 female anorexia nervosa patients. There was no difference between male and female patients in the age at onset. Male and female anorexia nervosa cases were very similar in their personality profile and symptomatology; however, male cases were more preoccupied in their thoughts with food, weight etc., and showed more hyperactivity, more achievement orientation and more sexual anxiety than female cases. The mothers' age at the male patients' birth was significantly younger than in the female group. Male anorexia nervosa patients were more extraverted and scored "superfeminine" on the masculinity vs feminity scale (FPI). A continuum from "true" anorexia nervosa to atypical cases and to secondary loss of appetite was observed.

    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.

    The present study compared effects of erotic and non-erotic depictions of male-male intimacy on the experience of anger in heterosexual men. Data came from three independent laboratory studies designed to elicit anger in response to erotic or non-erotic depictions of male-male and male-female intimacy. All participants completed a measure of sexual prejudice and anger was assessed before and after viewing the erotic or non-erotic video. Among high-prejudiced men, viewing erotic and non-erotic intimate behavior between two men elicited significant increases in anger relative to viewing comparable behavior between a male-female dyad. In contrast, among low-prejudiced men, viewing erotic, but not non-erotic, intimate behavior between two men elicited significant increases in anger relative to viewing comparable behavior between a male-female dyad. Implications for understanding heterosexual men's anger, and aggression, toward gay men were discussed. PMID:20818528

    In recent years, the public has become more aware that exposure of males to certain agents can adversely affect their offspring and cause infertility and cancer. The hazards associated with exposure to ionising radiation have been recognised for nearly a century, but interest was aroused when a cluster of leukaemia cases was identified in young children living in Seascale, close to the nuclear processing plant at Sellafield in West Cumbria. There was a civil court case on behalf of two of the alleged victims of paternal irradiation at Seascale against British Nuclear Fuels. The case foundered on 'the balance of probabilities'. Nevertheless, there was support for paternal exposure from Japanese experimental X-ray studies in mice. The tumours were clearly heritable as shown by F2 transmission. Also, effects of a relatively non-toxic dose of radiation (1Gy) on cell proliferation transmitted to the embryo were manifested in the germ line of adult male mice even after two generations. In addition in humans, smoking fathers appear to give rise to tumours in the F{sub 1} generation. Using rodent models, developmental abnormalities/congenital malformations and tumours can be studied after exposure of males in an extended dominant lethal assay and congenital malformations can be determined which have similar manifestations in humans. The foetuses can also be investigated for skeletal malformations and litters can be allowed to develop to adulthood when tumours, if present, can be observed. Karyotype analysis can be performed on foetuses and adult offspring to determine if induced genetic damage can be transmitted. Using this study design, cyclophosphamide, 1,3-butadiene and urethane have been examined and each compound produced positive responses: cyclophosphamide in all endpoints examined, 1,3-butadiene in some and urethane only produced liver tumours in F{sub 1} male offspring. This suggests the endpoints are determined by independent genetic events. The results from

    The symmetry and masculinity of the face are often considered important elements of male facial attractiveness. However, facial preferences are rarely studied on natural faces. We studied the effect of these traits and facial metric parameters on facial attractiveness in Spanish and Colombian raters. In total, 13 metric and 11 asymmetry parameters from natural, unmanipulated frontal face photographs of 50 Spanish men were measured with the USIA semiautomatic anthropometric software. All raters (women and men) were asked to rank these images as potential long-term partners for females. In both sexes, facial attractiveness was negatively associated with facial masculinity, and preference was not associated with facial symmetry. In Spanish raters, both sexes preferred male traits that were larger in the right side of the face, which may reflect a human tendency to prefer a certain degree of facial asymmetry. We did not find such preference in Colombian raters, but they did show stronger preference for facial femininity than Spanish raters. Present results suggest that facial relative femininity, which is expected to signal, eg good parenting and cooperation skills, may be an important signal of mate quality when females seek long-term partners. Facial symmetry appears unimportant in such long-term mating preferences.

    Survey of androgens and estrogens in serum, liver and testes of male yellow-bellied slider turtles, Trachemys (= Pseudemys) scripta, a species exhibiting dissociated gametogenesis age-dependent melanism, revealed the presence of numerous androgen precursors, androgens, androgen metabolites, and estrogens in quantities varying with season, tissue, and male coloration.The most commonly found and abundant androgens in all males were dehydroepiandrosterone (DHEA) and androstenedione, which were present at significantly higher levels in testes than in serum or liver.Epitestosterone was found in the serum and liver of only melanistic males; testosterone was only rarely recovered.Behavioral testing of castrated male turtles implanted with various androgens, as well as intact and sham-operated controls, revealed that melanistic males courted more frequently than nonmelanistic males, and that exogenous testosterone was most effective in inducing courtship behavior in castrated males.

  7. Meiosis in male Drosophila

    2012-01-01

    Meiosis entails sorting and separating both homologous and sister chromatids. The mechanisms for connecting sister chromatids and homologs during meiosis are highly conserved and include specialized forms of the cohesin complex and a tightly regulated homolog synapsis/recombination pathway designed to yield regular crossovers between homologous chromatids. Drosophila male meiosis is of special interest because it dispenses with large segments of the standard meiotic script, particularly recombination, synapsis and the associated structures. Instead, Drosophila relies on a unique protein complex composed of at least two novel proteins, SNM and MNM, to provide stable connections between homologs during meiosis I. Sister chromatid cohesion in Drosophila is mediated by cohesins, ring-shaped complexes that entrap sister chromatids. However, unlike other eukaryotes Drosophila does not rely on the highly conserved Rec8 cohesin in meiosis, but instead utilizes two novel cohesion proteins, ORD and SOLO, which interact with the SMC1/3 cohesin components in providing meiotic cohesion.

  8. Sport and male sexuality.

    2017-03-22

    The relationships between sport and sexuality in males are of great social and clinical interest, because of sports and motor activities that highly promote social and sexual relationships. Even if few literature exist, two main questions should be taken into account: whether and how physical exercise and sport positively or negatively influence sexual health and behavior and/or whether and how sexual behavior may affect a sub-sequent sport performance. Physical exercise and sport per se can influence, positively or negatively, the hypothalamic-pituitary-testicular axis function and, consequently, the individual's reproductive and/or sexual health. This depends on individual factors such as genetic and epigenetic ones and on different variables involved in the practice of sport activities (type of sport, intensity and duration of training, doping and drug use and abuse, nutrition, supplements, psychological stress, allostatic load, etc.). If well conducted, motor and sport activities could have beneficial effects on sexual health in males. Among different lifestyle changes, influencing sexual health, regular physical activity is fundamental to antagonize the onset of erectile dysfunction (ED). However, competitive sport can lead both reproductive and/or sexual tract damages and dysfunctions, transient (genital pain, hypoesthesia of the genitalia, hypogonadism, DE, altered sexual drive, etc.) or permanent (hypogonadism, DE, etc.), by acting directly (traumas of the external genitalia, saddle-related disorders in cyclists, etc.) or indirectly (exercise-related hypogonadism, drug abuse, doping, stress, etc.). Sexual activities shortly performed before a sport competition could differently influence sport performance. Due to the few existing data, it is advisable to avoid an absolute pre-competition sexual abstinence.

  9. [Obesity and male fertility].

    Obesity and male infertility have increased in the last decades; therefore, a possible association between these pathologies has been explored. Studies inform that obesity may affect fertility through different mechanisms, which alltogether could exert erectile dysfunction and/or sperm quality impairment. These include: 1) hypothalamic-pituitary-testicular (HPG) axis malfunction: obese hormonal profile is characterized by reduction of testosterone, gonadotrophins, SHBG and/or inhibin B concentrations (marker of Sertoli cells function) and hyperestrogenemy (consequence of aromatase overactivity ascribed to adipose tissue increase); 2) increased release of adipose-derived hormones: leptin increase could be responsible for some of the alterations on the HPG axis and could also exert direct deleterious effects on Leydig cells physiology, spermatogenesis and sperm function; 3) proinflammatory adipokines augmentation, higher scrotal temperature (due to fat accumulation in areas surrounding testes) and endocrine disruptors accumulation in adiposites, all of these responsible for the increase in testes oxidative stress and 4) sleep apnea, frequent in obese patients, suppresses the nocturnal testosterone rise needed for normal spermatogenesis. Finally, although controversial, all the above mentioned factors could comprise gametes quality; i.e. decrease sperm density and motility and increase DNA fragmentation, probably disturbing spermatogenesis and/or epididymal function. In summary, although obesity may impair male fertility by some/all of the described mechanisms, the fact is that only a small proportion of obese men are infertile, probably those genetically predisposed or morbidly obese. Nevertheless, it is likely that because the incidence of obesity is growing, the number of men with reduced fertility will increase as well.

  10. Success breeds success in mating male reed frogs (Hyperolius marmoratus).

    Studies of the distribution of mating success among males in frog choruses typically seek to identify specific phenotypic attributes that confer a higher mating success on certain individual males. These attributes invariably relate to competition among males: either direct competition in the form of aggression, or competition to attract and be chosen by females. In this paper, we present evidence that an additional factor may operate in frog choruses. We show that individual males who mate on a given night enjoy a higher probability of being successful on the next night, and we suggest that this is because successful mating enables males to conserve energy.

    Now-a-days reproductive health problems along with infertility in male is very often observed. Various Assisted Reproductive Technologies have been introduced to solve the problem, but common people cannot afford the cost of such procedures. Various ayurvedic and other alternative medicines, along with regular yoga practice are proven to be not only effective to enhance the reproductive health in men to produce a successful pregnancy, but also to regulate sexual desire in men who practice celibacy. Yoga is reported to reduce stress and anxiety, improve autonomic functions by triggering neurohormonal mechanisms by the suppression of sympathetic activity, and even, today, several reports suggested regular yoga practice from childhood is beneficial for reproductive health. In this regard the present review is aimed to provide all the necessary information regarding the effectiveness of yoga practice to have a better reproductive health and to prevent infertility.

    Coalitions influence the establishment and maintenance of social relationships among males in primate species. In this study, we compare the social behavior of males between two groups of Alouatta palliata: a group that was recently taken over by a coalition of two males (Mt), and a group that had a stable composition for at least 9 months (Rh). We predicted that coalition partners would be more cooperative and less competitive than dyads formed by immigrant and long-term resident males, and dyads formed by long-term resident males. Additionally, we predicted that these dyadic trends should be reflected in more competition and less cooperation in the group that was taken over. As predicted, the coalition partners of Mt showed the highest levels of cooperation among all dyads and the second lowest rate of agonism. Cooperation was higher in the group that had a stable composition. Results from this study suggest that the social relationships of male mantled howlers vary as a function of familiarity between males and that in the context of coalitionary takeovers, coalitionary males are highly cooperative. Cooperation is lower in groups recently taken over and competition is more intense, perhaps as a consequence of the process of establishment and reorganization of power relationships within some dyads. In the future, we must determine the frequency of coalitionary takeovers in this population and assess its ultimate consequences for male-male social relationships.

  15. Population density influences male-male competition in guppies.

    1999-12-01

    This study tested the general prediction that population density affects male-male competition, female mate choice and the opportunity for sexual selection. By manipulating the density of guppies, Poecilia reticulata, while keeping the sex ratio constant, I found that male mating tactics were phenotypically plastic with respect to density. As density increased, males decreased their courtship displays. Male-male competition and mate searching were highest at intermediate densities. Population density had no significant effect on the total number of copulations, copulatory tactics or the percentage of postcopulatory guarding. Female preference for males with a higher percentage of orange coloration was similar at all density levels. The 'opportunity for sexual selection', which estimates the upper limit to which a selected trait can shift if directional selection is operating and was calculated as the variance in number of copulations per male divided by the square of the mean number of copulations, was negatively associated with population density. This may be due to the decrease in male-male competition at high density rather than female preference which was similar across density treatments.

    Infertility is defined as a failure to conceive in a couple trying to reproduce for a period of two years without conception. Approximately 15 percent of couples are infertile, and among these couples, male factor infertility accounts for approximately 50 percent of causes. Male infertility is a multifactorial syndrome encompassing a wide variety of disorders. In more than half of infertile men, the cause of their infertility is unknown (idiopathic) and could be congenital or acquired. Infertility in men can be diagnosed initially by semen analysis. Seminograms of infertile men may reveal many abnormal conditions, which include azoospermia, oligozoospermia, teratozoospermia, asthenozoospermia, necrospermia and pyospermia. The current estimate is that about 30 percent of men seeking help at the infertility clinic are found to have oligozoospermia or azoospermia of unknown aetiology. Therefore, there is a need to find the cause of infertility. The causes are known in less than half of these cases, out of which genetic or inherited disease and specific abnormalities in the Y chromosome are major factors. About 10-20 percent of males presenting without sperm in the ejaculate carry a deletion of the Y chromosome. This deleted region includes the Azoospermia Factor (AZF) locus, located in the Yq11, which is divided into four recurrently deleted non-overlapping subregions designated as AZFa, AZFb, AZFc and AZFd. Each of these regions may be associated with a particular testicular histology, and several candidate genes have been found within these regions. The Deleted in Azoospermia (DAZ) gene family is reported to be the most frequently deleted AZF candidate gene and is located in the AZFc region. Recently, a partial, novel Y chromosome 1.6-Mb deletion, designated "gr/gr" deletion, has been described specifically in infertile men with varying degrees of spermatogenic failure. The DAZ gene has an autosomal homologue, DAZL (DAZ-Like), on the short arm of the chromosome 3 (3

    Achondroplasia is an autosomal dominant congenital disorder of enchondral ossification. It is clinically characterized by low stature, craniofacial deformity, and vertebral malformation. Associated ophthalmic features include telecanthus, exotropia, angle anomalies, and cone-rod dystrophy. A 24-year-old male presented with decreased vision bilaterally and typical achondroplasia. The best corrected visual acuity was 20/70 in both eyes. Anterior segment examination was normal. Fundus examination revealed a well-demarcated circular paramacular lesion in both eyes. As macular coloboma and achondroplasia are developmental disorders, the funduscopic examination is required in patients with achondroplasia.

    Double-orifice mitral valve (DOMV) is a relatively rare cardiac anomaly. Although usually associated with various cardiac anomalies, co-presence of DOMV and noncompaction of left ventricular myocardium (NCLVM) is extremely rare. Here, we present a 24-year-old male who underwent mitral valve repair using artificial chordae and annuloplasty at the posterior commissure for severe mitral regurgitation (MR), resulting from flail anterior leaflet of the larger postero-medial orifice and dilatation of left ventricle with NCLVM. One year later, he underwent second mitral valve repair for recurrence of MR. Further endoscopic evaluation of the left ventricle, and reinforcement via artificial ring, enabled us to achieve repair.

    Inflammatory Pseudotumour (IPT) of the spleen is an extremely rare benign lesion of the spleen. It presents as a well-circumscribed mass which is usually solitary and composed of foci of inflammatory cells, mainly plasma cells and lymphocytes in a fibroblastic stroma. We report the case of a 24 year old male who complained of pain in the abdomen, with one episode of vomiting. An ultrasound scan of the abdomen and a contrast enhanced abdominal CT scan showed the presence of a cystic lesion in the spleen. Following a splenectomy, however, it was histologically found to be an IPT of the spleen. PMID:23998094

    Differences in longevity between sexes is a mysterious yet general phenomenon across great evolutionary distances. To test the roles of responses to environmental cues and sexual behaviors in longevity regulation, we examined Caenorhabditis male lifespan under solitary, grouped, and mated conditions. We find that neurons and the germline are required for male pheromone-dependent male death. Hermaphrodites with a masculinized nervous system secrete male pheromone and are susceptible to male pheromone killing. Male pheromone-mediated killing is unique to androdioecious Caenorhabditis, and may reduce the number of males in hermaphroditic populations; neither males nor females of gonochoristic species are susceptible to male pheromone killing. By contrast, mating-induced death, which is characterized by germline-dependent shrinking, glycogen loss, and ectopic vitellogenin expression, utilizes distinct molecular pathways and is shared between the sexes and across species. The study of sex- and species-specific regulation of aging reveals deeply conserved mechanisms of longevity and population structure regulation.

    Thyrotoxic crisis is a medical emergency requiring early diagnosis and urgent management, which can be challenging due to its diverse clinical presentations. While common presentations include fever, sweating, palpitations, tremors and confusion, presence of jaundice is rare. We report a 35-year-old male who presented with jaundice due to cholestasis along with other features of thyrotoxic crisis due to Graves' disease. He had a good clinical recovery with resolution of cholestasis following treatment for thyrotoxic crisis. Jaundice can be a rare manifestation of thyrotoxic crisis, and should be considered in the differential diagnosis when other clinical features of thyrotoxic crisis are present. However secondary causes of jaundice should be looked into and excluded.

  1. Males do not see only red: UV wavelengths and male territorial aggression in the three-spined stickleback ( Gasterosteus aculeatus)

    Animal colour signals serve important functions in intraspecific interactions, including species recognition, mate choice and agonistic behaviour. An increasing interest concerns ultraviolet (UV) wavelengths, for instance studies on the effect of UV in mating decisions. More recently, some studies also established that UV signals affect intrasexual interactions. We studied the role of UV during aggressive encounters between male three-spined sticklebacks ( Gasterosteus aculeatus), a species in which UV has an effect on female and male mate choice and shoaling behaviour. To that aim, we compared the aggressive response of a territorial male to male intruders, either seen in UV-including (UV+) or UV-lacking (UV-) conditions. Our prediction was that, if UV wavelengths are used in male-male competition, a territorial male should show less competitive behaviour towards an intruder representing a lower threat, i.e. the one presented without UV light. Male sticklebacks showed significantly lower levels of aggression towards male opponents lacking an UV component to their coloration than male opponents possessing this colour component. Discrimination was not influenced by a difference in brightness between the UV+ and UV- stimuli. Finally, we present some reflectance-spectrophotometrical data of two skin regions (cheek and abdomen) of the experimental males and analysed relationships between colorimetric variables, body variables and behaviour. Our study emphasises that UV visual cues are of importance in different communicational tasks in the three-spined stickleback.

    Gynecomastia is a benign enlargement of the male breast caused by the proliferation of glandular breast tissue. Determining the various causes of gynecomastia such as physiological causes, drugs, systemic diseases, and endocrine disorders is important. Androgen insensitivity syndrome (AIS) is a rare endocrine disorder presenting with gynecomastia and is a disorder of male sexual differentiation caused by mutations within the androgen receptor gene. All individuals with AIS have the 46 XY karyotype, although AIS phenotypes can be classified as mild, partial or complete and can differ among both males and females including ambiguous genitalia or infertility in males. We experienced a case of partial AIS presenting with gynecomastia and identified the androgen receptor gene mutation.

    The abuse of flunitrazepam (FZ) compounds is worldwide, and several studies have reflected on the consequences with regard to violence, aggression and criminal lifestyle of FZ users. Criminals take high doses of FZ or some other benzodiazepines to "calm down" before the planned crime. There is support from earlier studies that most likely, all benzodiazepines may increase aggression in vulnerable males. Chronic intake of high doses of FZ increases aggression in male rats. Because psychopathy involves aggression, we have examined whether psychopathy as well as any of the four facets of the Psychopathy Checklist-Revised (PCL-R) (Interpersonal, Affective, Lifestyle and Antisocial) are related to different substance use disorders, with the focus on FZ. We have also examined the relationship between each PCL-R item and FZ use. Participants were 114 male offenders aged 14-35 years, all of whom were convicted for severe, predominantly violent, offences. Substance use, including FZ, was not more common in those who scored high in psychopathy. Use of FZ was more common in offenders who scored high in Facet 4 (Antisocial) of the PCL-R (odds ratio = 4.30, 95% CI 1.86-9.94). Only one of the PCL-R items, "Criminal versatility", was significantly associated with FZ use (odds ratio = 3.7). It may be concluded that intake of FZ has a specific relationship to only one of the facets and not to psychopathy per se. The findings have also important theoretical implications because Facet 4 is not a key factor of the construct of psychopathy. Clinical implications of the article: We have used the new two-factor and four-facet theoretical model of psychopathy in the young offender population, many of them with one or more substance use disorders. The present results suggest that antisocial behavior defined by Facet 4 (poor behavioral control, early behavior problems, juvenile delinquency, revocation of conditional release and criminal versatility) in the studied subjects is more typical

  4. Giant Intraperitoneal Multiloculated Pseudocyst in a Male

    PubMed Central

    2016-01-01

    Intraperitoneal pseudocysts are rare and may be difficult to differentiate from other malignant neoplasms. Reports of occurrences are mainly associated with long-term intraperitoneal catheter use, intraperitoneal catheter infections, or major pelvic surgery in females, although there are few reported incidences without prior trauma. We present a case of a male patient found to have a 19 × 15 × 9 cm intraperitoneal pseudocyst with other multiloculated areas and a history of a right inguinal hernia repair. After a thorough review of the literature, this is the first multiloculated nonpancreatic pseudocyst reported in a male patient. PMID:27022497

    Many male reproductive system problems could be perceived as being embarrassing, which may be one of the reasons that they are often not identified in general practice. This article provides an overview of some common problems affecting the male reproductive system, and outlines current treatment options. Erectile dysfunction, premature ejaculation, loss of libido, testicular cancer and prostate disease may cause embarrassment to the patient and, occasionally, the general practitioner. We describe how patients affected by these conditions may present to general practice, and discuss the reasons why they may not present. We also discuss how GPs can overcome difficulties in identifying and dealing with their male patients suffering from male reproductive system issues.

    Dermatoglyphics in infertile male patients were studied and compared with that of age matched controls to see whether any specific dermatoglyphic pattern exists in infertile male patients. Infertile male patients with abnormal semen profile were referred to Cytogenetic Laboratory for karyotyping. We selected twenty-four infertile male patients with abnormal semen profile. Out of twenty-four infertile male patients, nineteen were with normal Karyotype and five patients were with abnormal Karyotype. Loop was the commonest pattern observed in the infertile male patients. All these fingertip and palmar dermatoglyphic findings were compared with that of result on finger and palmar dermatoglyphics of equal number of age matched controls. Statistical evaluation was done with software "EPI- info, version-6.04 d". Infertile males had reduced number of loops as compared to that of controls which was statistically significant. Total whorls were increased in infertile male patients as compared to that of controls which was statistically insignificant. Percentage of true palmar pattern in I 3 and I 4 areas was reduced in infertile male patients as compared to that of controls which was statistically insignificant.

    Perceived peer alcohol use is a predictor of consumption in college males; frequent references to alcohol on Facebook may encourage alcohol consumption. Content analysis of college males' Facebook profiles identified references to alcohol. The average age of 225 identified profiles was 19.9 years. Alcohol references were present on 85.3% of the profiles; the prevalence of alcohol was similar across each undergraduate grade. The average number of alcohol references per profile was 8.5 but increased with undergraduate year (p = .003; confidence interval = 1.5, 7.5). Students who were of legal drinking age referenced alcohol 4.5 times more than underage students, and an increase in number of Facebook friends was associated with an increase in displayed alcohol references (p < .001; confidence interval = 0.009, 0.02). Facebook is widely used in the college population; widespread alcohol displays on Facebook may influence social norms and cause increases in male college students' alcohol use.

    2015-05-16

    Obesity is now common and this may have altered visual perceptions of what constitutes a 'normal' and therefore healthy weight. The present study examined cross-cultural differences in male and female participants' ability to visually identify the weight status of photographed Caucasian males. Five hundred and fifty three male and female young adults from the US (high obesity prevalence), UK and Sweden (lower obesity prevalence) participated in an online study. Participants judged the weight status of a series of photographed healthy weight, overweight and obese (class I) Caucasian males and rated the extent to which they believed each male should consider losing weight. There was a strong tendency for both male and female participants to underestimate the weight status of the photographed overweight and obese males. Photographed males were frequently perceived as being of healthier weight than they actually were. Some modest cross-cultural differences were also observed; US participants were worse at recognising obesity than UK participants (p < 0.05) and were also significantly more likely to believe that the photographed obese males did not need to consider losing weight, in comparison to both the UK and Swedish participants (ps < 0.05). No cross-cultural differences were observed for perceptions or attitudes towards the photographed healthy weight or overweight males. The weight status of overweight and obese (class I) Caucasian males is underestimated when judged by males and females using visual information alone. This study provides initial evidence of modest cross-cultural differences in attitudes toward, and the ability to recognise, obesity in Caucasian males.

    2002-03-01

    Hemophilia is a rare disorder affecting 1 in 5,000 males. Because hemophilia-associated hemorrhage may occur at anytime, affected males frequently seek care in the ED. We studied the epidemiology of ED visits by males with hemophilia. The medical records of all identified Coloradan males with hemophilia who sought care in Colorado EDs in 1998 were reviewed. Fifty-one males with hemophilia had a total of 125 ED visits; hemorrhage accounted for 64.8% of visits (95% CI=55.6, 73.1). On 13.0% (95% CI=6.4, 22.6) of visits for hemorrhage, treatment was warranted, but not given. On 12.3% (95% CI=5.5, 22.8) of visits when treatment was given, there were errors in product choice or dose. Documentation of factor concentrate brand and lot number was present for just 13.9% (95% CI=6.5, 24.7) and 24.6% (95% CI=14.8, 36.9) of visits, respectively. There is substantial room for improvement in the prescribing practices and documentation related to hemophilia care in the ED. Available resources should be utilized by ED physicians.

  11. Mitochondria, maternal inheritance, and male aging.

    PubMed

    Camus, M Florencia; Clancy, David J; Dowling, Damian K

    2012-09-25

    The maternal transmission of mitochondrial genomes invokes a sex-specific selective sieve, whereby mutations in mitochondrial DNA can only respond to selection acting directly on females. In theory, this enables male-harming mutations to accumulate in mitochondrial genomes when these same mutations are neutral, beneficial, or only slightly deleterious in their effects on females. Ultimately, this evolutionary process could result in the evolution of male-specific mitochondrial mutation loads; an idea previously termed Mother's Curse. Here, we present evidence that the effects of this process are broader than hitherto realized, and that it has resulted in mutation loads affecting patterns of aging in male, but not female Drosophila melanogaster. Furthermore, our results indicate that the mitochondrial mutation loads affecting male aging generally comprise numerous mutations over multiple sites. Our findings thus suggest that males are subject to dramatic consequences that result from the maternal transmission of mitochondrial genomes. They implicate the diminutive mitochondrial genome as a hotspot for mutations that affect sex-specific patterns of aging, thus promoting the idea that a sex-specific selective sieve in mitochondrial genome evolution is a contributing factor to sexual dimorphism in aging, commonly observed across species.

    Reports of mammary-gland tumors in male dogs are lacking. To describe the clinical characteristics of mammary-gland tumors in male dogs. Eight male dogs diagnosed with mammary-gland tumors. Retrospective study. Medical databases from 3 institutions were searched. Medical records were abstracted, and owners and referring veterinarians contacted for follow-up information. Tissues were reviewed for histologic type, and immunohistochemical staining for estrogen and progesterone receptors (ER, PR) was performed. Eight dogs with histologically confirmed mammary-gland tumors were included in this retrospective study. Median age at diagnosis was 11.5 years. Four dogs were sexually intact; 4 were neutered. All were purebred. Mammary-gland tumors were incidental findings in 7 of 8 dogs. All dogs were treated with only surgical excision. All but 1 dog had benign epithelial tumors. The dog with the malignant tumor was the only dog to develop possible local recurrence but de novo tumor development cannot be excluded. No dog had evidence of metastatic disease at diagnosis. Based on institutional population data, it was determined that female dogs are 62 times more likely to develop mammary-gland tumors than male dogs (P < .001). Estrogen-receptor expression was strong in the majority of tumors; progesterone-receptor expression, although present in all tumors, was less intense. CONCLUSIONS/CLINICAL IMPORTANCE: This study suggests that mammary-gland tumors in male dogs are rare, usually benign, and surgery alone can provide long-term control in most dogs.

  13. Mammography Findings of Male Breast Diseases

    Over the past 2 decades, the percentage of men presenting with breast complaints has increased from 0.8% to 2.4%, and men now account for 1% of all breast cancer cases. The most common male breast mass is gynecomastia, followed by lipoma and epidermal inclusion cysts. Because there is a paucity of parenchyma as compared with the female breast, the malignancy rapidly progresses to the next stage, with the appearance of secondary signs like nipple retraction, fixation to deeper tissues, skin ulceration or adenopathy. Diagnostic evaluation is needed only when the palpable mass is unilateral, hard, fixed, peripheral to the nipple, or associated with nipple discharge, skin changes, or lymphadenopathy. Male breast cancer usually occurs in a subareolar location or is positioned eccentric to the nipple; occasionally, it occurs in a peripheral position. Secondary signs like skin thickening, nipple retraction, and axillary lymphadenopathy may be seen. Microcalcifications can occur. Mammography can accurately distinguish between malignant and benign male breast disease. Radiologists are generally less familiar with breast disease in males compared with females. In this article, we discuss the clinical, and mammographic features of a variety of benign and malignant diseases that can occur in the male breast.

  14. Progesterone impairs social recognition in male rats.

    PubMed

    Bychowski, Meaghan E; Auger, Catherine J

    2012-04-01

    The influence of progesterone in the brain and on the behavior of females is fairly well understood. However, less is known about the effect of progesterone in the male system. In male rats, receptors for progesterone are present in virtually all vasopressin (AVP) immunoreactive cells in the bed nucleus of the stria terminalis (BST) and the medial amygdala (MeA). This colocalization functions to regulate AVP expression, as progesterone and/or progestin receptors (PR)s suppress AVP expression in these same extrahypothalamic regions in the brain. These data suggest that progesterone may influence AVP-dependent behavior. While AVP is implicated in numerous behavioral and physiological functions in rodents, AVP appears essential for social recognition of conspecifics. Therefore, we examined the effects of progesterone on social recognition. We report that progesterone plays an important role in modulating social recognition in the male brain, as progesterone treatment leads to a significant impairment of social recognition in male rats. Moreover, progesterone appears to act on PRs to impair social recognition, as progesterone impairment of social recognition is blocked by a PR antagonist, RU-486. Social recognition is also impaired by a specific progestin agonist, R5020. Interestingly, we show that progesterone does not interfere with either general memory or olfactory processes, suggesting that progesterone seems critically important to social recognition memory. These data provide strong evidence that physiological levels of progesterone can have an important impact on social behavior in male rats. Copyright © 2012 Elsevier Inc. All rights reserved.

    Male microchimerism, the presence of a small number of male cells, in women has been attributed to prior pregnancies. However, male microchimerism has also been reported in women with only daughters, in nulliparous women and prepubertal girls suggesting that other sources of male microchimerism must exist. The aim of the present study was to examine the presence of male microchimerism in a cohort of healthy nulliparous Danish girls aged 10-15 y using DNA extracted from cells from whole blood (buffy coats) and report the association with potential sources of male cells. A total of 154 girls were studied of which 21 (13.6%) tested positive for male microchimerism. There was a tendency that girls were more likely to test positive for male microchimerism if their mothers previously had received transfusion, had given birth to a son or had had a spontaneous abortion. Furthermore, the oldest girls were more likely to test positive for male microchimerism. However, less than half of microchimerism positivity was attributable to these factors. In conclusion, data suggest that male microchimerism in young girls may originate from an older brother either full born or from a discontinued pregnancy or from transfusion during pregnancy. We speculate that sexual intercourse may be important but other sources of male cells likely exist in young girls.

  16. Developmental aspects of the male reproductive system

    PubMed Central

    Davies, Jack

    1978-01-01

    The development of the mammalian reproductive system involves: (1) an indifferent or ambisexual stage, in which both the male (Wolffian) and female (Mullerian) duct systems are present; (2) sexual differentiation, in which the phenotypic sex is expressed by the enhancement of Mullerian structures in the female and Wolffian structures in the male and reciprocal suppression of the opposite duct system; (3) cytodifferentiation, in which the epithelial, stromal and muscular features are regionally established; and (4) actual response to endogenous hormones, especially in mammals, such as the human and guinea pig, in which the differentiated tissues respond according to their capability. Specifically in the male, the onset of sexual differentiation is signaled by the elaboration of an androgenlike material (possibly testosterone) and a Mullerian-inhibiting factor from the testis. In the absence of these two influences, or one of them, the reproductive tract remains essentially female in configuration, a normal situation in the female and in abnormal males in which the urogenital sinus and Wolffian structures are incapable of hormonal responses due to the lack of specific enzymes or receptors. Male differentiation in particular involves enlargement of the penis and its canalization by the urethra, scrotal development and descent of the testis, and the formation of accessory glandular structures from the urogenital sinus or Wolffian ducts (bulbourethral gland, seminal vesicles, ampulla, prostate). Remnants of the Mullerian system may persist at the upper pole of the testis and are normally present (uterus masculinus) in relation to the prostatic part of the urethra. The emergence of the characteristic parts of the male reproductive system in higher mammals in relation to phylogeny and the detailed origin of these in individual ontogeny are described.

    Early-life social isolation has profound effects on adult social competence. This is often expressed as increased aggression or inappropriate displays of courtship-related behaviors. The social incompetence exhibited by isolated animals could be in part due to an altered ability to participate in communicatory exchanges. House mice (Mus musculus) present an excellent model for exploring this idea, because social isolation has a well-established influence on their social behavior, and mice engage in communication via multiple sensory modalities. Here, we tested the prediction that social isolation during early life would influence ultrasonic vocalizations (USVs) emitted by adult male mice during same-sex social encounters. Starting at three weeks of age, male mice were housed individually or in social groups of four males for five weeks, after which they were placed in one of three types of paired social encounters. Pair types consisted of: two individually housed males, two socially housed males, or an individually housed and a socially housed male (“mixed” pairs). Vocal behavior (USVs) and non-vocal behaviors were recorded from these 15-minute social interactions. Pairs of mice consisting of at least one individually housed male emitted more and longer USVs, with a greater proportional use of USVs containing frequency jumps and 50-kHz components. Individually housed males in the mixed social pairs exhibited increased levels of mounting behavior towards the socially housed males. Mounting in these pairs was positively correlated with increased number and duration of USVs as well as increased proportional use of spectrally more complex USVs. These findings demonstrate that USVs are part of the suite of social behaviors influenced by early-life social isolation, and suggest that altered vocal communication following isolation reflects reduced social competence.

    DRESS syndrome (Drug Rash with Eosinophilia and Systemic Symptoms) is a potentially life-threatening syndrome, which reflects a serious hypersensitivity reaction to drugs, presenting by generalized skin rash, fever, eosinophilia, atypical lymphocytosis, and internal organ involvement. Herein a 21-month old male infant with DRESS and Encephalopathy syndrome is presented who complicated after phenobarbital usage that persisted due to phenytoin cream usage. The case received phenobarbital after a seizure disorder presented as "status epilepticus". He developed drug eruption, fever, hepatosplenomegaly, increased liver enzymes, encephalopathy and progressive loss of consciousness with extensive hyperintense white matter lesions in brain MRI. After discontinuation of phenobarbital and phenytoin, all symptoms were resolved, while brain MRI became normal after two months. To our best knowledge, this is the first reported case that developed leukoencephalopathy along with DRESS syndrome.

    Hemophilia A is a X-linked hereditary condition that lead to decreased factor VIII activity, occurs mainly in males. Decreased factor VIII activity leads to increased risk of bleeding events. During neonatal period, diagnosis is made after post-partum bleeding complication or unexpected bleeding after medical procedures. Subgaleal hemorrhage during neonatal period is a rare, severe extracranial bleeding with high mortality and usually related to traumatic labor or coagulation disorders. Subgaleal hemorrhage complications result from massive bleeding. We present a neonate with unremarkable family history and uneventful pregnancy with a vaginal delivery with no instrumentation, presenting with severe subgaleal bleeding at 52 hours of life. Aggressive support measures were implemented and bleeding managed. The unexpected bleeding lead to a coagulation study and the diagnosis of severe hemophilia A. There were no known sequelae. This case shows a rare hemophilia presentation reflecting the importance of coagulation studies when faced with unexplained severe bleeding. PMID:26734126

    An obese diabetic male presented with self limiting diarrhoea of 1 day duration, which had started after he ate sausages. Examination was unrevealing except for persistent low blood pressure. Computed tomographic (CT) scan, done to rule out retroperitoneal bleed, incidentally showed air in the gall bladder. He underwent emergent cholecystectomy, and a gangrenous gall bladder that grew Clostridium perfringens was removed. Emphysematous cholecystitis is not so infrequent, although only rarely does it present as diarrhoea alone. A high index of clinical suspicion is necessary as even advanced presentation can be subtle and appropriate radio imaging essential. Although abdominal radiograph and ultrasound could be useful, a CT scan is diagnostic. The CT scan and its classical finding confirmed the diagnosis, and it reiterates the importance of timely identification and urgent action, as emphysematous cholecystitis is associated with high mortality.

    What possesses someone to volunteer and go through hoops and red tape to make a presentation at a conference? For that matter, why does anyone ever present anything to anyone? Actually, presentations are a fact of life and there are many reasons for doing a presentation and doing it well. New and existing staff need training and orientation to the way things are done here. Handing all of them a manual and hoping they read it is pretty much a waste of paper. On the other hand, an effective, entertaining and upbeat presentation on the relevant topics is more likely to stick with those people. They will even have a name and face to remember and seek out when they have an issue on or with that topic. This can be a very effective beginning for networking with new peers. The presenter is seen as knowledgeable, as a source of information on company topics and possibly evaluated as a potential mentor or future manager. Project staff and/or peers benefit from clear, concise, presentations of topical knowledge. This is one way that a group working on various aspects of the same project or program can stay in touch and in step with each other. Most importantly, presentations may be the best or only door into the minds (and budgets) of management and customers. These presentations are a wonderful opportunity to address legal and compliance issues, budget, staffing, and services. Here is a chance, maybe the only one, to demonstrate and explain the wonderfulness of a program and the benefit they get by using the services offered most effectively. An interactive presentation on legal and compliance issues can be an effective tool in helping customers and/or management make good risk management decisions.

  2. Male tolerance and male-male bonds in a multilevel primate society.

    2014-10-14

    Male relationships in most species of mammals generally are characterized by intense intrasexual competition, with little bonding among unrelated individuals. In contrast, human societies are characterized by high levels of cooperation and strong bonds among both related and unrelated males. The emergence of cooperative male-male relationships has been linked to the multilevel structure of traditional human societies. Based on an analysis of the patterns of spatial and social interaction in combination with genetic relatedness data of wild Guinea baboons (Papio papio), we show that this species exhibits a multilevel social organization in which males maintain strong bonds and are highly tolerant of each other. Several "units" of males with their associated females form "parties," which team up as "gangs." Several gangs of the same "community" use the same home range. Males formed strong bonds predominantly within parties; however, these bonds were not correlated with genetic relatedness. Agonistic interactions were relatively rare and were restricted to a few dyads. Although the social organization of Guinea baboons resembles that of hamadryas baboons, we found stronger male-male affiliation and more elaborate greeting rituals among male Guinea baboons and less aggression toward females. Thus, the social relationships of male Guinea baboons differ markedly from those of other members of the genus, adding valuable comparative data to test hypotheses regarding social evolution. We suggest that this species constitutes an intriguing model to study the predictors and fitness benefits of male bonds, thus contributing to a better understanding of the evolution of this important facet of human social behavior.

  13. Sexual bipotentiality of behavior in male and female goldfish.

    2013-01-15

    It is known that in goldfish Carassius auratus, a non-sex changing fish, prostaglandin (PG) treatment can induce female-typical sex behavior in males, and androgen treatment can induce male-typical sex behavior in females. These facts suggest that goldfish have a sexually bipotential brain even after attaining sexual maturity unlike mammals which have sexually differentiated brain. In the present study, in order to further characterize the brain function of goldfish, whether hormonal treatments which induce heterotypical sexual behavior suppress the occurrence of sex-typical behavior and whether sex-typical and heterotypical behavior can be induced in a relatively short time were examined. In the first series of experiments, male goldfish were shown to retain their ability to perform male-typical sex behavior within a week after being induced to perform female-typical behavior. Likewise, female goldfish were also shown to retain their female-typical sex behavior a week after being induced to perform male-typical behavior. In the second series of experiments, when PG-injected experimental males were placed with both PG-injected females and sexually mature males, the experimental males performed male- and female-typical behavior alternately with the females and the males, respectively during 90 min test period. When methyltestosterone-treated experimental females were injected with PG and placed with both PG-injected females and mature males, the experimental females performed male- and female-typical behavior alternately during 90 min test period. The results of the present study are consistent with the current knowledge that goldfish possess a sexually bipotential brain that can regulate both male and female-typical sex behaviors.

    Spermatogenesis is a highly orchestrated developmental process by which spermatogonia develop into mature spermatozoa. This process involves many testis- or male germ cell-specific gene products whose expressions are strictly regulated. In the past decade the advent of high-throughput gene expression analytical techniques has made functional genomic studies of this process, particularly in model animals such as mice and rats, feasible and practical. These studies have just begun to reveal the complexity of the genomic landscape of the developing male germ cells. Over 50% of the mouse and rat genome are expressed during testicular development. Among transcripts present in germ cells, 40% – 60% are uncharacterized. A number of genes, and consequently their associated biological pathways, are differentially expressed at different stages of spermatogenesis. Developing male germ cells present a rich repertoire of genetic processes. Tissue-specific as well as spermatogenesis stage-specific alternative splicing of genes exemplifies the complexity of genome expression. In addition to this layer of control, discoveries of abundant presence of antisense transcripts, expressed psuedogenes, non-coding RNAs (ncRNA) including long ncRNAs, microRNAs (miRNAs) and Piwi-interacting RNAs (piRNAs), and retrogenes all point to the presence of multiple layers of expression and functional regulation in male germ cells. It is anticipated that application of systems biology approaches will further our understanding of the regulatory mechanism of spermatogenesis.† PMID:19306351

  15. Systems Toxicology of Male Reproductive Development ...

    EPA Pesticide Factsheets

    Adverse trends in male reproductive health have been reported for increased rates of testicular germ cell tumor, low semen quality, cryptorchidism, and hypospadias. An association with prenatal environmental exposure has been inferred from human and animal studies underlying male reproductive developmental defects. The present study established the links between environmental chemicals, molecular targets, and adverse outcomes using U.S. EPA animal study (ToxRefDB) and high-throughput screening (ToxCast) databases. This systems-based approach revealed a phenotypic hierarchy across 63 chemicals and a pleiotropic in vitro bioactivity profile. Although estrogenic and anti-androgenic activities have been extensively studied in male reproductive developmental toxicity, the present study showed these receptor targets to be only a subset of the potential landscape of molecular targets. A variety of chemical (e.g. phthalates, conazoles, carbamates, and phenol compounds) and bioactivity (e.g. nuclear receptors, vascular remodeling proteins, and cytochrome-P450 reductases) clusters further suggested multiple pathways leading to the adverse outcomes. This points to the need for multi-scale systems models to predict whether the occurrence of one adverse outcome may predict the risk of another. Imbalances in androgen and estrogen signaling have been a general focus in male reproductive toxicology research. While a number of recent studies have demonstrated that both hormonal

    For several decades, testosterone and its synthetic derivatives have been used with anabolic and androgenic purposes. These substances were first restricted to professional bodybuilders, but become more and more popular among recreational athletes. Up to date, 3,000,000 anabolic-androgenic steroids (AAS) users have been reported in the United States with an increasing prevalence, making AAS consumption a major public health growing concern. Infertility is defined by the WHO as the failure to achieve a clinical pregnancy after 12 months or more of regular unprotected sexual intercourse and a male factor is present in up to 50 % of all infertile couples. Several conditions may be related to male infertility. Substance abuse, including AAS, is commonly associated to transient or persistent impairment on male reproductive function, through different pathways. Herein, a brief overview on AAS is offered. Steroids biochemistry, patterns of use, physiological and clinical issues are enlightened. A further review about fertility outcomes among male AAS abusers is also presented, including the classic reports on transient anabolic steroid-induced hypogonadism (ASIH), and the more recent experimental reports on structural and genetic sperm damage.

    Elite male artistic gymnasts (AG) are exposed to high levels of physical and psychological stress during adolescence and experience a significant late maturation in both linear growth and pubertal development. The aim of the present study was to determine the impact of intensive physical training on the adult final height in elite male AG. This study is unique in character, as all variables were measured on the field of competition. The study was prospective and longitudinal; however, the current analysis of data is cross-sectional. Data from 86 elite male AG were obtained during the gymnastics competitions of European and World Championships. Clinical evaluation included height and weight measurements, as well as assessment of pubic hair and genital development according to Tanner's stages of pubertal development. The laboratory investigation included determination of skeletal maturation. All athletes completed a questionnaire that included questions on personal (onset and intensity of training, number of competitions per year) and family data (paternal and maternal heights). Male AG were below the 50th percentile for both final height and weight. Elite male AG had final height standard deviation score (SDS) lower than their genetic predisposition. Final height SDS was correlated positively with target height SDS (r = 0.430, p < 0.001) and weight SDS (r = 0.477, p < 0.001) and negatively to the intensity of training (r = -0.252, p = 0.022). The main factors influencing final height, by multiple regression analysis were weight SDS (p < 0.001) and target height SDS (p = 0.003). In elite maleAG, final height falls short of genetic predisposition, still well within normal limits. Considering medical and psychological risks in general, and based on the results of this research project, the International Federation of Gymnastics has increased the age limit for participants in international gymnastics competitions by 1 year.

    In this study, we examine the evolution of tradition concerning infant male circumcision, utilizing evidence from classical medical texts as well as information from literature, legal sources and art. We examined the differences in the representation of male circumcision between ancient times and the modern era. Through the ages, male circumcision has been differently represented, and at present an interesting representation is born following the natural evolution of society. Based on the fact that the foreskin is not a defect, the impact of male circumcision is on the child's rights and its role during first years of life still remains controversial.

    Background Cancers of the male urethra constitute less than 1% of all malignant urological tumours, and the occurrence of sarcomas in the urethra is even less frequent. To our knowledge, only one case has been previously described in the English literature. Case presentation We report the clinical features, histology, imaging and treatment of urethral leiomyosarcoma in a male patient. Conclusion The occurrence of sarcoma in the urethra is most unusual, and its appearance as a primary growth in the male urethra is not recorded in the English literature. In conclusion, this case highlights a rare type of primary male urethral malignancy that features a poor prognosis. PMID:19946451

    2004-12-01

    We investigate the evolution of male morphology in the fig wasps belonging to the genus Philotrypesis (Chalcidoidea, Sycorectinae). We first reconstruct the phylogenetic relationships of Philotrypesis associated with African figs using nuclear and mitochondrial DNA. We then determine male morphotypes in the species included in our phylogeny and show that intraspecific polymorphism is common. Most species present two types of males and some species have up to three types. These morphotypes are believed to represent alternative mating tactics: some males show morphological adaptations to fighting, others are winged dispersers and others are small sneakers. Mapping out these variations onto our phylogeny reveals that the combination of morphs changes randomly along the branches of the tree. Both parsimony and likelihood approaches indicate that there has been at least one transition from dimorphism to trimorphism, several gains and losses of the small morph and two independent acquisitions of the winged morph. Using maximum likelihood analyses of character evolution, we estimate transition rates for each morph and show that the evolution of each type of morph are not correlated and that forward and backward transition rates are not significantly different. Our results altogether suggest that male morphology is evolutionary labile, it responds quickly to selection imposed by the mating environment. This study, also suggests that seemingly complex phenotypes, such as winged males, can evolve several times and can even be recreated after having been lost.

    Previous research established that male androphilia (i.e., sexual arousal and attraction to adult males) clusters in families. Some studies find that male androphilia clusters in both the paternal and maternal lines, while others find that it clusters only in the latter. Most of the research investigating the familial nature of male androphilia has taken place in Western cultural contexts that are problematic for such research because they are characterized by low fertility. To address this, our previous work has examined familial patterning of male androphilia in Samoa, a high-fertility population in which androphilic males are readily identified due to their public status as fa'afafine (a third gender category). Building on this work, the present study replicated the familial nature of male androphilia in Samoa using a sample size that was ~122% larger than the one we previously employed (N = 382, M ±SD age: 29.72 years ±10.16). Samoan fa'afafine had significantly more fa'afafine relatives in their maternal and paternal lines compared to Samoan gynephilic males (p < .001). The prevalence of male androphilia was equivalent across both the paternal and maternal lines (all p > .15). The revised prevalence estimate of male androphilia in Samoa falls between 0.61% and 3.51%.

    Chondroid syringoma (CS) is a rare benign tumor of the sweat gland. It generally presents as a painless, slowly growing, subcutaneous swelling, typically located on the head and neck region. The majority of the cases develop in middle aged and elderly males. We present a case of CS located over the right thumb of a 25-year-old male. The diagnosis was made initially by cytological evaluation and later confirmed by histopathological examination. There was no recurrence on two year follow up after the complete surgical excision of the tumor.

  10. Hybrid male sterility between Drosophila willistoni species is caused by male failure to transfer sperm during copulation.

    PubMed

    Civetta, Alberto; Gaudreau, Chelsea

    2015-05-01

    The biological concept of species stresses the importance of understanding what mechanisms maintain species reproductively isolated from each other. Often such mechanisms are divided into premating and postmating, with the latest being the result of either prezygotic or postzygotic isolation barriers. Drosophila willistoni quechua and Drosophila willistoni willistoni are two subspecies that experience reproductive isolation. When a D. w. quechua female is crossed with a D. w. willistoni male, the hybrid males (F1QW) are unable to father progeny; however, the reciprocal cross produces fertile hybrids. Thus, the mechanism of isolation is unidirectional hybrid male sterility. However, the sterile F1QW males contain large amounts of motile sperm. Here we explore whether pre-copulatory or post-copulatory pre-zygotic mechanisms serve as major deterrents in the ability of F1QW males to father progeny. Comparisons of parental and hybrid males copulation durations showed no significant reduction in copulation duration of F1QW males. Interrupted copulations of the parental species confirmed that sperm transfer occurs before the minimum copulation duration registered for F1QW males. However, we found that when females mate with F1QW males, sperm is not present inside the female storage organs and that the lack of sperm in storage is due to failure to transfer sperm rather than spillage or active sperm dumping by females. Sterility of F1QW hybrid males is primarily driven by their inability to transfer sperm during copulation.

  11. Male genital trauma

    Jordan, G.H.; Gilbert, D.A.

    1988-07-01

    We have attempted to discuss genital trauma in relatively broad terms. In most cases, patients present with relatively minimal trauma. However, because of the complexity of the structures involved, minimal trauma can lead to significant disability later on. The process of erection requires correct functioning of the arterial, neurologic, and venous systems coupled with intact erectile bodies. The penis is composed of structures that are compliant and distensible to the limits of their compliance. These structures therefore tumesce in equal proportion to each other, allowing for straight erection. Relatively minimal trauma can upset this balance of elasticity, leading to disabling chordee. Likewise, relatively minimal injuries to the vascular erectile structures can lead to significantly disabling spongiofibrosis. The urethra is a conduit of paramount importance. Whereas the development of stricture is generally related to the nature of the trauma, the extent of stricture and of attendant complications is clearly a function of the immediate management. Overzealous debridement can greatly complicate subsequent reconstruction. A delicate balance between aggressive initial management and maximal preservation of viable structures must be achieved. 38 references.

  12. Immunology and male infertility.

    PubMed

    Mumford, D M

    1978-10-01

    This article has attempted to review evidence that suggests that immune factors may be operative in a small but significant number of infertile men. Although our current understanding of the possible processes by which autosensitization to previously sequestered reproductive antigens occurs is incomplete, there are laboratory assays presently available that give an indication, but do not prove, that immune factors may be contributing to the infertile state. Continued research is needed to develop new assays and more purified sperm antigens, which might enhance our knowledge of the underlying immunoreproductive changes. Until these are available, the following procedures should be considered when investigating a patient with infertility of suspected immune origin. The patient's history should be taken, and a physical examination should be performed. A complete blood count, urinalysis, and complete semen analysis and culture should be taken. Next, in vivo cervical tests (Sims-Huhner) are performed, followed by sperm antibody assessment (serum, semen) and perhaps in vitro cervical mucus sperm assays (especially the crossed hostility test). After the tests have been completed, the following possibe treatments exist: 1. Treatment of underlying infections 2. Correction of obstructions 3. Corticosteroid (or testosterone?) therapy 4. Washed sperm insemination 5. First portion of fresh ejaculate insemination 6. Artificial insemination with homologous donor 7. Adoption.

    Rett syndrome (RS; MIM 312750) is a severe neurological disorder affecting exclusively females. Its prevalence is about 1 in 10 000 female births, and it is a prominent cause of profound mental handicap in women. RS is caused by mutations in the X‐linked methyl CpG‐binding protein 2 (MECP2) gene. These mutations were initially thought to be lethal in males. However, MECP2 mutations are now frequently identified in mentally retarded male patients. The frequency of disease‐causing MECP2 mutations in this population is between 1.3% and 1.7%. Surprisingly, MECP2 mutations in males are responsible for a wide spectrum of neurological disorders, ranging from mild mental retardation to severe neonatal encephalopathy. The aim of this review is to describe the nature of the MECP2 mutations identified in male patients to date and their associated phenotypes. PMID:17351020

    Male reproductive health has deteriorated in many countries during the last few decades. In the 1990s, declining semen quality has been reported from Belgium, Denmark, France, and Great Britain. The incidence of testicular cancer has increased during the same time incidences of hypospadias and cryptorchidism also appear to be increasing. Similar reproductive problems occur in many wildlife species. There are marked geographic differences in the prevalence of male reproductive disorders. While the reasons for these differences are currently unknown, both clinical and laboratory research suggest that the adverse changes may be inter-related and have a common origin in fetal life or childhood. Exposure of the male fetus to supranormal levels of estrogens, such as diethlylstilbestrol, can result in the above-mentioned reproductive defects. The growing number of reports demonstrating that common environmental contaminants and natural factors possess estrogenic activity presents the working hypothesis that the adverse trends in male reproductive health may be, at least in part, associated with exposure to estrogenic or other hormonally active (e.g., antiandrogenic) environmental chemicals during fetal and childhood development. An extensive research program is needed to understand the extent of the problem, its underlying etiology, and the development of a strategy for prevention and intervention. Images Figure 3.

    Blanchard's (J Nerv Ment Dis 177:616-623, 1989) theory of autogynephilia suggests that male-to-female transsexuals can be categorized into different types based on their sexuality. Little previous research has compared the sexuality of male-to-female transsexuals to biological females. The present study examined 15 aspects of sexuality among a non-clinical sample of 234 transsexuals and 127 biological females, using either an online or a paper questionnaire. The results showed that, overall, transsexuals tended to place more importance on partner's physical attractiveness and reported higher scores on Blanchard's Core Autogynephilia Scale than biological females. In addition, transsexuals classified as autogynephilic scored significantly higher on Attraction to Feminine Males, Core Autogynephilia, Autogynephilic Interpersonal Fantasy, Fetishism, Preference for Younger Partners, Interest in Uncommitted Sex, Importance of Partner Physical Attractiveness, and Attraction to Transgender Fiction than other transsexuals and biological females. In accordance with Blanchard's theory, autogynephilia measures were positively correlated to Sexual Attraction to Females among transsexuals. In contrast to Blanchard's theory, however, those transsexuals classified as autogynephilic scored higher on average on Sexual Attraction to Males than those classified as non-autogynephilic, and no transsexuals classified as autogynephilic reported asexuality.

    Male boreal toads (Bufo boreas) are thought to return to the breeding site every year but, if absent in a particular year, will be more likely to return the following year. Using Pollock's robust design we estimated temporary emigration (the probability a male toad is absent from a breeding site in a given year) at three locations in Colorado, USA: two in Rocky Mountain National Park and one in Chaffee County. We present data that suggest that not all male toads return to the breeding site every year. Our analyses indicate that temporary emigration varies by site and time (for example, from 1992 to 1998, the probability of temporary emigration ranged from 10% to 29% and from 3% to 95% at Lost Lake and Kettle Tarn, respectively). Although the results provide weak evidence that males are more likely to return after a year's hiatus, a general pattern of state-dependent temporary emigration was not supported. We also hypothesized relationships between temporary emigration and a number of weather variables. While some competitive models included weather covariates, imprecise and variable estimates of the effects of these covariates precluded fully defining their impact on temporary emigration. ?? 2006 by the Ecological Society of America.

    Chused, J F

    1999-12-01

    One consequence of a heightened interest in intersubjectivity in the current psychoanalytic literature has been a relative neglect of the examination of unconscious fantasies. Presenting material from the analysis of three males, each of whom, in childhood and/or adolescence, hid his penis between his legs and looked at himself in a mirror naked, the author demonstrates the importance of attending to both unconscious fantasies and their manifestations within the interactive field of analysis. The first patient is a young child with a gender identity disorder, whose wish to be like his mother was a response to the emotional loss of her during early childhood. The second patient is an adolescent, whose behaviour in front of a mirror was a manifestation of his desire to possess his mother and be her, to humiliate and sadistically control her, and at the same time, to experience the masochistic sexual gratification of being a seemingly helpless victim. The third patient, a 48-year-old male, came to analysis filled with suicidal impulses and self-hatred related to homosexual impulses. His repeated examination of himself in a mirror, with penis hidden, reflected severe castration anxiety, related to an ambivalent relationship with an angry mother and a longing for attention from an unavailable father. The article closes with a description of the similarities and differences in the dynamics of these three males as well as a discussion of the meaning of similar behaviour in other males seen in consultation.

    Male breast cancer (MBC) is an uncommon disease whose molecular profile is not well known. X chromosome gain has been described as a marker of aggressive behavior in female breast cancer. The aim of this study is to investigate the role of the X chromosome in male breast cancer. Twenty cases of male breast invasive ductal carcinoma were retrieved and compared with 10 cases of gynecomastia. Cases were tested by fluorescence in situ hybridization to assess a cytogenetic profile for the X chromosome. The X chromosome status was compared with histopathologic features and stage at presentation. All MBC cases harbored an X chromosome gain (100%) in a variable percentage of neoplastic cells, ranging from 31% to 85% (mean, 59%). On the contrary, all cases of gynecomastia showed wild X chromosome asset. The patients' age at surgery and tumor grading showed a statistically significant correlation (P = .0188-.04), with the percentages of neoplastic cells showing an X chromosome gain. These data suggest that this X chromosome gain plays a role in the neoplastic transformation of male breast epithelial cells.

    The pressure to establish the Dunedin (New Zealand) Male Advice Clinic came from members of the Psychology Department of the University of Otago as a result of a study of attitudes towards the use and purchase of contraceptives among the local young people. The study findings and the suggestions made for the establishment of a male advice center are summarized. 3 samples were studied: a university sample (N=80); a sample of high school students (N=243); and a general population sample (N=70). The males in all samples were questioned regarding the process of purchasing contraceptives. The study findings indicated that embarrassment functioned as an impediment to obtaining contraceptive supplies. 76% of the university sample, 36% of the school sample, and 57% of the general population thought that males needed advice in choosing condoms. The male advice center would be open to anyone but designed specifically to cater to young men who anticipate or are already engaged in sexual intercourse. Services available would include contraceptive advice, contraceptive supplies, and sexual advice and counseling. Initial interest in the Dunedin Male Advice Clinic was considerable, but the question remained as to whether the group for whom the clinic was intended was really reached.

    Pharmacokinetics of leptin in mammals has not been studied in detail and only one study has examined more than one time point in non-mutant mice and this was in a female mice. This is the first study to describe leptin distribution over a detailed time course in normal male mice. A physiologic dose (12 ng) of radiolabelled leptin was injected into adult male mice via the lateral tail vein and tissues were dissected out and measured for radioactivity over a time course of up to two hours. Major targets were the digestive tract, kidneys, skin and lungs. The brain was not a major target, and 0.15% of the total dose was recovered from the brain 5 min after administration. Major differences appear to exist in the distribution of leptin between the male and female mice, indicating a high degree of sexual dimorphism. Although the half-lives were similar between male and female mice, almost twice the proportion of leptin was recovered from the digestive tract of male mice in comparison to that reported previously for females. This would seem to indicate a major difference in leptin distribution and possibly function between males and females. PMID:27998953

    A review of Texas death certificates for 1975-84 identified 779 civilian males whose deaths were homicides that occurred in the workplace. Injuries from firearms caused 81 per cent of the deaths. The overall rate of workplace homicide was 2.1/100,000 male workers/year. Males employed in taxicab service had the highest rate of workplace homicide. 78.2/100,000 male workers/year. Males employed in certain retail trade industries, law enforcement, and the private-security industry also had high rates of workplace homicide. Male workers greater than or equal to 65 years old were at especially high risk, with a workplace-homicide rate 3.5 times that of younger workers. A review of medical examiners' records in five urban counties indicated that 32 per cent of victims who had worked in eating-and-drinking places and 5 per cent of other workers had blood or cerebrospinal-fluid alcohol levels greater than or equal to 0.10 g/dl. These results provide a base for designing effective strategies to prevent workplace homicides.

    The atypical antipsychotics have been touted by many as having minimal extrapyramidal symptoms. This case series from the Tripler Army Medical Center Psychiatry Graduate Medical Education Program presents the extrapyramidal symptoms observed with four different atypical antipsychotic medications. Also reviewed are the mechanisms of action that atypical antipsychotics and first-generation antipsychotics use to treat the symptoms of schizophrenia. Cases reviewed include a schizophrenic male patient whose dose of risperidone was doubled from 6mg to 12mg overnight and developed an acute dystonic reaction; a young male patient with a substance-induced psychosis who unintentionally doubled his ziprasidone dose in 24 hours, resulting in an acute dystonic reaction; a young female patient on paroxetine who also recently started olanzapine and had complaints consistent with akathisia that resolved with treatment; and an adolescent female patient on escitalopram for obsessive-compulsive disorder who after starting aripiprazole developed Parkinsonism. All four cases illustrate that even though atypical antipsychotics are less likely to cause extrapyramidal symptoms than their first generation cousins, the physician should be aware that these symptoms may still occur and need to be treated.

    We report an extremely rare case of the oropharyngeal form of tularaemia, causing a parapharyngeal abscess. A 48-year-old woman presented with fever, sore throat, breathing difficulty and a right-sided neck swelling. This mass had previously been treated with penicillin without response, and had already been surgically drained once in another hospital. On physical examination, the tonsils were exudative and hypertrophic and the pharynx was hyperaemic. A fluctuant, 4 × 4 cm mass was seen on endoscopic examination, originating from the left parapharyngeal area and protruding towards the pyriform sinus, and partly obstructing the airway. Microagglutination test antibody titres for Francisella tularensis were positive (1/1280). The patient healed completely after definitive drainage of the abscess and antimicrobial therapy for 14 days (streptomycin, 2 × 1 g intramuscularly). Tularaemia should be considered in the differential diagnosis of patients presenting with tonsillopharyngitis, cervical lymphadenitis and parapharyngeal abscess who do not respond to treatment with penicillin, even if they do not live in an endemic region.

  9. Does large body size in males evolve to facilitate forcible insemination? A study on garter snakes.

    PubMed

    Shine, Richard; Mason, Robert T

    2005-11-01

    A trend for larger males to obtain a disproportionately high number of matings, as occurs in many animal populations, typically is attributed either to female choice or success in male-male rivalry; an alternative mechanism, that larger males are better able to coercively inseminate females, has received much less attention. For example, previous studies on garter snakes (Thamnophis sirtalis parietalis) at communal dens in Manitoba have shown that the mating benefit to larger body size in males is due to size-dependent advantages in male-male rivalry. However, this previous work ignored the possibility that larger males may obtain more matings because of male-female interactions. In staged trials within outdoor arenas, larger body size enhanced male mating success regardless of whether a rival male was present. The mechanism involved was coercion rather than female choice, because mating occurred most often (and soonest) in females that were least able to resist courtship-induced hypoxic stress. Males do physically displace rivals from optimal positions in the mating ball, and larger males are better able to resist such displacement. Nonetheless, larger body size enhances male mating success even in the absence of such male-male interactions. Thus, even in mating systems where males compete physically and where larger body size confers a significant advantage in male-male competition, the actual selective force for larger body size in males may relate to forcible insemination of unreceptive females. Experimental studies are needed to determine whether the same situation occurs in other organisms in which body-size advantages have been attributed to male-male rather than male-female interactions.

  10. [Male to female transsexualism].

    The transsexual is a person who suffers from a deep identity disturbance caused by physical characteristics which do not correspond to mental traits and tendencies. The persistent sense of contradiction between his or her deceptive sexual appearance and his or her inner perception, causes a strong desire to achieve harmonization of the two. This aspiration, even if modification of chromosomal sex is impossible, can be fulfilled by undergoing SRS (Sex Reassignment Surgery). SRS represents the last major step of a clinical, therapeutic and diagnostic program involving skilled professionals in the physical and psychological sciences. Their assistance and counseling helps the patient to calmly and consciously decide to undergo SRS. A surgeon has the obligation not only to validate the operation outcome, but to also to maintain a long-term follow-up. A transsexual is not just like any other person; he or she should therefore be treated with sympathy and understanding. The surgeon should try his best to establish a relationship of mutual trust, taking into account the causes of anxiety and stress felt by the patient, and keeping in mind the ultimate objective, which is an improvement in the quality of life. At present, the most widely used surgical techniques are the Simple Penile Skin Inversion, the Penile-scrotal flap Inversion and the enterovaginoplasty. Each surgical technique has its own advantages and disadvantages, and it is up to the surgeon, in discussion with the patient, to make the appropriate choice. The surgical technique performing the Simple Penile Skin Inversion seems to ensure a better cosmetic appearance and an adequate lubrication, but a lower rate of satisfaction, in relation to the neocavity depth. On the contrary, the Penile-Scrotal Flap Inversion guarantees an adequate vaginal depth and lubrication, even though the cosmetic appearance is not always completely satisfactory. In our experience, a significant number of patients were satisfied with the

  1. Caring for female patients: The experiences of male nurses.

    PubMed

    Keogh, Brian; Gleeson, Madeline

    This article presents the results of two small qualitative studies, which examined the experiences of six male registered psychiatric nurses (RPN) and five male registered general nurses (RGN) when caring for patients of the opposite sex. Semi-structured interviews were used to collect the data. The focus of the interviews was an attempt to describe the male nurses' experiences of caring for women with a particular emphasis on interventions that involved physical touch. Themes were generated from both studies and the common themes are presented here. Male nurses in this study were often apprehensive about using physical touch and they used coping strategies in response to their fears of being accused of using touch inappropriately. Several factors also influenced the male nurses when using physical touch as an intervention. These findings suggest that learning about caring for female patients needs to be included in the undergraduate curriculum and that further research on the experience of men as nurses is required.

    In the advent of mass voluntary medical male circumcision (VMMC) for the partial prevention of HIV, previously rare adverse events associated with adult male circumcision are likely to be encountered with higher frequency. Fournier's gangrene, defined as a polymicrobial necrotizing fasciitis of the perineal, perianal or genital areas, is one such rare and life-threatening adverse event. In this report, we present two cases that were identified in the context of a VMMC programme over a 3-year period during which approximately 100,000 adult circumcisions were performed. Case 1: A 19-year-old male who had VMMC performed using the dorsal slit technique developed pain and blisters on the scrotal skin on the sixth postoperative day. He had no co-morbidities, and serology for HIV was negative. On examination, locally he had scrotal skin necrosis with an offensive odour and was dehydrated but afebrile. Repeated aggressive debridement was done while he stayed in a hospital for 3 weeks; at which point, he had healthy granulation tissue and was free of infection. The wound had closed spontaneously and completely by the fifth month. Case 2: A 52-year-old male who had VMMC performed with the sleeve resection method developed pain and swelling of the penis and scrotum on the fourth postoperative day. He had a low-grade fever of 37.6°C. He was not diabetic or immunosuppressed and had a negative HIV serology. He was admitted and was given IV antibiotics, and repeated aggressive debridement was performed. On the third week of hospitalization, he had healthy granulation tissue and received a split skin graft on the penile shaft. At 4 months, the scrotal defect had completely closed. Fournier's gangrene is a rare occurrence after adult male circumcision with associated high morbidity. These are the first descriptions in the VMMC era.

  5. The visual system of male scale insects.

    Animal eyes generally fall into two categories: (1) their photoreceptive array is convex, as is typical for camera eyes, including the human eye, or (2) their photoreceptive array is concave, as is typical for the compound eye of insects. There are a few rare examples of the latter eye type having secondarily evolved into the former one. When viewed in a phylogenetic framework, the head morphology of a variety of male scale insects suggests that this group could be one such example. In the Margarodidae (Hemiptera, Coccoidea), males have been described as having compound eyes, while males of some more derived groups only have two single-chamber eyes on each side of the head. Those eyes are situated in the place occupied by the compound eye of other insects. Since male scale insects tend to be rare, little is known about how their visual systems are organized, and what anatomical traits are associated with this evolutionary transition. In adult male Margarodidae, one single-chamber eye (stemmateran ocellus) is present in addition to a compound eye-like region. Our histological investigation reveals that the stemmateran ocellus has an extended retina which is formed by concrete clusters of receptor cells that connect to its own first-order neuropil. In addition, we find that the ommatidia of the compound eyes also share several anatomical characteristics with simple camera eyes. These include shallow units with extended retinas, each of which is connected by its own small nerve to the lamina. These anatomical changes suggest that the margarodid compound eye represents a transitional form to the giant unicornal eyes that have been described in more derived species.

  7. Development of male-fertility-regulating agents.

    1991-09-01

    Steroidal, nonsteroidal, plant-derived, gonadotropin-related and immunological agents investigated for control of male fertility are reviewed with brief descriptions of their effects, and illustrations of their structures. The physiology of the male reproductive system is presented as an introduction: an ideal male antifertility agent would inhibit spermatogenesis at the level of the Sertoli cells, without affecting endogenous androgen production by Leydig cells, needed for libido and potency. Androgens down-regulate their own production at physiological levels, but few long-acting orally active derivatives are available. Anti-androgens with mixed androgen and progestin activity, combined with a pure androgen are potentially useful. Androgen-progestin combinations are being tested by WHO as implants. Dozens of miscellaneous nonsteroidal compounds have been discovered serendipitously to have antifertility activity in men or male animals, including alkylating agents antimetabolites, antibiotics, sulfa derivatives, fungicides, trichomonocides, amebicides, alpha blockers, antimalarials, coumarins, and carbohydrate derivatives. Various plant alkaloids have been screened. Those of Hibiscus, Vitex and Plumbago species, as well as Tripterygium wilfordii glycosides, which are being evaluated in combination with gossypol, are mentioned here. Gossypol has been thoroughly tested in China, but rejected because of its side effects, particularly hypokalemic paralysis, its low therapeutic index, and uncertain recovery of fertility. Gonadotropin-releasing hormone (GnRH) agonists and antagonists are being researched in combination with androgens with some success. The GnRH antagonists to date have low activity , or cause histamine-related side effects at higher doses; the androgens require a new route such as a long-acting implant to overcome the need for daily injections. Immunological contraception for males has not progressed beyond the research stage.

    Background and Objectives The emerging science demonstrates various health benefits associated with infant male circumcision and adult male circumcision; yet rates are declining in the United States. The American Academy of Pediatrics and the Centers for Disease Control and Prevention recommend that healthcare providers present evidence-based risk and benefit information for infant male circumcision to parent(s) and guardian(s). The purpose of this study was to assess providers’ level of infant male circumcision knowledge and to identify the associated characteristics. Methods An online survey was administered to healthcare providers in the family medicine, obstetrics, and pediatrics medical specialties at an urban academic health center. To assess infant male circumcision knowledge, a 17 point summary score was constructed to identify level of provider knowledge within the survey. Results Ninety-two providers completed the survey. Providers scored high for the following knowledge items: adverse event rates, protects against phimosis and urinary tract infections, and does not prevent hypospadias. Providers scored lower for items related to more recent research: protection against cervical cancer, genital ulcer disease, bacterial vaginosis, and reduction in HIV acquisition. Two models were constructed looking at (1) overall knowledge about male circumcision, and (2) knowledge about male circumcision reduction in HIV acquisition. Pediatricians demonstrated greater overall infant male circumcision knowledge, while obstetricians exhibited significantly greater knowledge for the HIV acquisition item. Conclusion Providers’ knowledge levels regarding the risks and benefits of infant male circumcision are highly variable, indicating the need for system-based educational interventions. PMID:25635664

    Faeces provide relevant biological information which includes, with the application of genetic techniques, the sex and identity of individuals that defecated, thus providing potentially useful data on the behaviour and ecology of individuals, as well as the dynamics and structure of populations. This paper presents estimates of the sex ratio of different felid species (jaguar, Panthera onca; puma, Puma concolor; and ocelot/margay, Leopardus pardalis/Leopardus wiedi) as observed in field collected faeces, and proposes several hypotheses that could explain the strikingly high proportion of faeces from male jaguars. The proportion of male and female faeces was estimated using a non-invasive faecal sampling method in 14 study areas in Mexico and Brazil. Faecal samples were genetically analysed to identify the species, the sex and the individual (the latter only for samples identified as belonging to jaguars). Considering the three species, 72.6% of faeces (n = 493) were from males; however, there were significant differences among them, with the proportion from males being higher for jaguars than for pumas and ocelots/margays. A male-bias was consistently observed in all study areas for jaguar faeces, but not for the other species. For jaguars the trend was the same when considering the number of individuals identified (n = 68), with an average of 4.2±0.56 faeces per male and 2.0±0.36 per female. The observed faecal marking patterns might be related to the behaviour of female jaguars directed toward protecting litters from males, and in both male and female pumas, to prevent interspecific aggressions from male jaguars. The hypothesis that there are effectively more males than females in jaguar populations cannot be discarded, which could be due to the fact that females are territorial and males are not, or a tendency for males to disperse into suboptimal areas for the species.

Faecal samples were genetically analysed to identify the species, the sex and the individual (the latter only for samples identified as belonging to jaguars). Considering the three species, 72.6% of faeces (n = 493) were from males; however, there were significant differences among them, with the proportion from males being higher for jaguars than for pumas and ocelots/margays. A male-bias was consistently observed in all study areas for jaguar faeces, but not for the other species. For jaguars the trend was the same when considering the number of individuals identified (n = 68), with an average of 4.2±0.56 faeces per male and 2.0±0.36 per female. The observed faecal marking patterns might be related to the behaviour of female jaguars directed toward protecting litters from males, and in both male and female pumas, to prevent interspecific aggressions from male jaguars. The hypothesis that there are effectively more males than females in jaguar populations cannot be discarded, which could be due to the fact that females are territorial and males are not, or a tendency for males to disperse into suboptimal areas for the species.

    The degree to which females are consistent in their mate preferences has implications for studies of sexual selection. Because choice of females for particular males may be affected by temporal changes in male characteristics, consistency of mate preferences of individual females of Poecilia reticulata was studied by presenting them with the same male pairs in consecutive trials under three experimental procedures: live males behind clear glass, live males behind one-way glass and images of males on videotape. Although females did not habituate to males in any of the experiments, they spent significantly more time in proximity to males behind clear glass than in the video and one-way glass presentations. Females preferred the bright male over the pale one in the video and the clear glass presentations, but not in the one-way glass experiment. Repeatability of preferences by individual females for a male was high in the video and one-way glass presentations but low in the clear-glass experiment. Behavioural interactions with the male in the clear-glass experiment affected both the time that females spent viewing males as well as female visual preferences. Results indicate that the video playback is not only useful for detecting differences between female preferences for morphological traits of male guppies, but is also much more effective in detecting preferences than the other two techniques, because it eliminates temporal variation in male behaviour.

    Two samples, male college students and convicted male child sex offenders, are compared on their abilities to accurately estimate the age group of a series of photographs of a sole female ranging in age from 11 to 29. Both samples tend to overestimate the age group of the subject photos, and no significant difference was found between college students and convicted child sex offenders in their ability to estimate the age of females. Both groups are compared demographically, and only limited differences were found. The implications are discussed in regard to theory and prevention of child sexual abuse.

    Two castrated male dogs presented for evaluation of tenesmus. Presurgical evaluations included complete physical examinations, serum biochemistry, abdominal ultrasonography, and MRI (case 2 only). Paraprostatic cysts were diagnosed in both cases based on the results of abdominal ultrasonography, MRI, and histopathology of tissue samples obtained during exploratory laparotomy. To the authors' knowledge, the two cases presented herein are the first documented cases of paraprostatic cysts that developed after castration in male dogs. Paraprostatic cysts should be considered in the differential diagnoses for castrated male dogs with prostatic disease.

    Inbreeding can cause reductions in fitness, driving the evolution of pre- and postcopulatory inbreeding avoidance mechanisms. There is now considerable evidence for such processes in females, but few studies have focused on males, particularly in the context of postcopulatory inbreeding avoidance. Here, we address this topic by exposing male guppies (Poecilia reticulata) to either full-sibling or unrelated females and determining whether they adjust investment in courtship and ejaculates. Our results revealed that males reduce their courtship but concomitantly exhibit short-term increases in ejaculate quality when paired with siblings. In conjunction with prior work reporting cryptic female preferences for unrelated sperm, our present findings reveal possible sexually antagonistic counter-adaptations that may offset postcopulatory inbreeding avoidance by females.

    We present a case of inferior conjunction in a rare type of conjoined twins, dicephalus in a male fetus. The male fetus was born to a 24-year-old, gravida 2, and para 0, who had medical abortion at 15 weeks of gestation due to anencephaly with meningoencephalocele revealed by ultrasound examination. The fetus was born with 2 anencephalic heads with a bifurcation of the vertebral column and presence of 2 spinal cords. The other viscera and limbs were normal in number and location as for a male singleton. This case illustrates the relationship between conjoined twining, and neural tube defect more particularly anencephaly with a male zygote, which is an unusual presentation for this type of zygote gender.

    Preliminary data are presented on 53 urban Mexican males interviewed during 1970-1971 in a study of homosexual encounters in a large Mexican city. These data are compared with data from recent studies in the United States and England of male homosexual behavior. Although preliminary and limited, the Mexican data indicate that cultural factors are important determinants of life styles and sex practices of homosexual males. Forty-eight of the 53 (90%) preferred and usually practiced anal intercourse, four preferred oral contacts, and one preferred mutual masturbation. Interviewees were also grouped according to major type of sex activity during the first sustained year of homosexual activity after puberty. One intragroup comparison indicates significant differences between anal active and anal passive interviewees. For example, as children anal passive subjects had significantly more homosexual contacts with adults; they also considered themselves more effeminate and as children were more involved with female sex-typed activities. Comparison of data from the English and United States studies with the present data suggests that preference for a particular sexual technique is not as developed in the former two countries; when there is a preference, it is not usually for anal intercourse.

  1. Acute alcohol exposure markedly influences male fertility and fetal outcome in the male rat.

    Although it is recognized that drugs ingested by pregnant females produce marked cognitive and physiological deficits in their offspring, the possibility that paternal exposure to drugs prior to mating may have adverse effects on fertility and fetal outcome has not received much attention. The purpose of the present studies was to examine whether a single, acute exposure to alcohol influences the subsequent ability of adult male rats to mate and produce healthy and viable litters. Our results showed that a relatively large dose of alcohol 24 hours prior to breeding had little effect on the mating behavior of male rats, but there were markedly fewer pregnancies in females mated with alcohol-exposed male rats than in controls. Of equal importance, we found that, even when conception occurred and live births were produced, there were striking differences in fetal outcome. Alcohol-treated males sired many fewer pups than control males and there was a markedly enhanced mortality rate in their offspring. Collectively, these data suggest that acute paternal alcohol administration 24 hours prior to breeding does not affect mating behavior, but results in a greatly diminished fertility rate and fewer and less viable offspring. These studies suggest that paternal alcohol use may be as important as maternal alcohol abuse as a negative variable in pregnancy and fetal outcome.

    The present study examined 25 male prisoners with a history of heroin dependency (M = 35.3 yr., SD = 8.5, range = 21-48) and 25 male prisoners with no history of substance abuse (M = 31.5 yr., SD = 9.8, range = 19-47) who were selected to complete the Emotion Regulation Questionnaire. Results showed that the group with a history of heroin dependency used a cognitive reappraisal strategy less frequently than controls and that there was no difference in the use of expression suppression strategies between the two groups. It was concluded that the negative impact of heroin abuse on an individual's emotion regulation is primarily reflected in the cognitive reappraisal dimension.

    The present study investigated the relative age effect, a biased distribution of elite athletes' birthdates, in Japanese male athletes. Japan applies a unique annual-age grouping for sport and education, which is from April 1 to March 31 of the following year. A total of 4,318 male athletes was evaluated from 12 sports: baseball, soccer, basketball, volleyball, handball, golf, horse racing, rugby, American football, sumo, Ekiden (track and field in long distance), and badminton. They played in the top level of Japanese leagues for each sport in 2010. The distribution of the birth dates was examined in each sport and showed significant relative age effect in baseball, soccer, volleyball, Ekiden, basketball, sumo, and horse racing, but not in all sports. The findings suggest that although the school year in Japan starts on April 1, significant relative age effects are observed in some sporting events.

  4. A probability sample of gay males.

    1990-01-01

    Data are presented from a national probability sample of males interviewed by telephone and asked their sexual orientation. Of these males 3.7 percent reported that they were homosexual or bisexual. Homosexual/bisexual men were compared with heterosexual ones on the demographic variables. This sample produced larger numbers in those groups which appear to be underrepresented in the usual samples drawn from the gay world. These groups include those with little education, married men, older men, minorities, and those living in small towns. It is suggested that probability samples which do not draw directly or heavily from the gay world for homosexual respondents obtain a broader sampling of those having homosexual feelings or behaviors.

    Exposure to drinking water containing as much as 500 ppm aluminum chloride for periods of 30, 60, and 90 days had no apparent effect on male reproductive processes. In an attempt to correlate enzyme activity with particular spermatogenic cell types, postnatal development of testicular enzymes was studied. Eight enzymes were selected: hyaluronidase (H), lactate dehydrogenase isoenzyme-X (LDH-X), dehydrogenases of sorbitol (SDH), α-glycerophosphate (GPDH), glucose-6-phosphate (G6PDH), malate (MDH), glyceraldehyde-3-phosphate (G3PDH), and isocitrate (ICDH). Enzyme specific activities in testicular homogenates were determined. Two types of enzyme developmental patterns were observed. One was represented by H, LDH-X, SDH, and GPDH; and the other by G6PDH, MDH, G3PDH, and ICDH. The former was characterized by a change in enzyme activities from low in newborn to high in adult while in the latter this pattern was reversed. The two complementary enzyme systems crossed each other at puberty. Prior to puberty, only spermatogonial cells are present; sperm differentiation initiated at puberty adds spermatocytes and spermatids to the testicular cell population. Male rats were exposed to borax in their diet for periods of 30 and 60 days. Concentrations of boron were 0, 500, 1000, and 2000 ppm. At the end of each experimental period, the specific activities of the selected enzymes were determined in the testis and prostate. Correlations of enzyme activity with testicular histology and androgen activities of the male accessory organs were sought. In addition, plasma FSH, LH, and testosterone levels were measured to assess pituitary-testicular interaction. Plasma and testicular boron concentrations were determined and a minimum boron concentration which induced germinal aplasia and male infertility was estimated. In both 30 and 60 day feeding studies, male rats receiving 500 ppm failed to demonstrate any significant adverse effects. In contrast, male rats receiving 100 and 2000 ppm

    2014-05-01

    Male infertility, affecting around half of the couples with a problem to get pregnant, is a very heterogeneous condition. Part of patients are having a defect in spermatogenesis of which the underlying causes (including genetic ones) remain largely unknown. The only genetic tests routinely used in the diagnosis of male infertility are the analyses for the presence of Yq microdeletions and/or chromosomal abnormalities. Various other single gene or polygenic defects have been proposed to be involved in male fertility. Yet, their causative effect often remains to be proven. The recent evolution in the development of whole genome-based techniques may help in clarifying the role of genes and other genetic factors involved in spermatogenesis and spermatogenesis defects.

  7. Hormonal contraception in the male.

    PubMed

    Anderson, R A

    2000-01-01

    The hormonal approach to male contraception is based on the suppression of gonadotrophin secretion with secondary suppression of spermatogenesis. This can be achieved by administration of testosterone or other androgen alone, but combined administration with a progestogen or GnRH analogue allows the dose of testosterone to be reduced to physiological replacement doses. This approach has been investigated for many years but without identification of a regimen which results in sufficient suppression of spermatogenesis to provide ensured contraception in all men, safely and conveniently. The reasons for this are discussed, and recent developments towards a regimen that fulfills all these criteria are described. Crucial to development of any new product is that it will be used: surveys of both men and women indicate firmly positive attitudes towards a 'male pill'. There are, therefore, grounds for cautious optimism that the next decade may see the introduction of the first novel male contraceptive for several hundred years.

    Introduction. This is a case report on male anorgasmia that was successfully treated with oxytocin. Oxytocin is increased during arousal and peaks during orgasm. More recently, a study on humans published in Nature has shown its value in social bonding, increasing trust, and enhancing the sense of well-being. Aim. To test the effectiveness of administering oxytocin in a case of treatment-resistant anorgasmia. Methods. The patient underwent a biopsychosocial evaluation by a psychiatrist trained in sexual medicine and sex therapy for male orgasmic disorder, acquired type. Medical conditions, effect of substances, and psychological issues were ruled out. The patient was properly consented to using oxytocin as an off-label trial. Oxytocin was administered using a nasal spray intracoitally because of its ultra-short half-life. Results. Oxytocin was effective in restoring ejaculation. Conclusions. A case of treatment-resistant male anorgasmia was successfully treated with intracoital administration of intranasal oxytocin.

    The purpose of the research was to determine (1) the difference in the rate of penile circumference increase per unit time between a group of young and a group of old normal males when exposed to the same erotic movie and (2) the correlation coefficient between penile shaft temperature increase and penile circumference increase. Ten males aged 19-30 years and ten males aged 48-65 years served as subjects. Each subject placed a thermistor and strain gauge on his penis and both outputs were recorded simultaneously on a two-channel recorder. The younger group responded at an erection rate 5.8 times faster than that of the older group. The correlation coefficient, based on the percent approach to oral temperature (98.6 degrees F) and the percent increase in penile circumference, was 0.75.

    Research has generally supported the existence of familial-genetic factors for male sexual orientation, but has not shed much light on the specific nature of those influences. Gay men with gay brothers provide the opportunity to examine several hypotheses. Sixty-six men, representing 37 gay male sibling pairs, completed questionnaires assessing behavior on various measures including childhood and adult gender nonconformity, timing of awareness of homosexual feelings, self-acceptance, and the quality of family relationships. Consistent with prior findings using twins, gay brothers were similar in their degree of childhood gender non-conformity, suggesting that this variable may distinguish etiologically (e.g., genetically) heterogeneous subtypes. The large majority of gay men with brothers knew about their own homosexual feelings before they learned about their brothers' homosexual feelings, suggesting that discovery of brothers' homosexuality is not an important cause of male homosexuality.

    Understanding the factors that account for male mating competitiveness is critical to the development of the sterile insect technique (SIT). Here, the effects of partial sterilization with 90 Gy of radiation on sexual competitiveness of Anopheles coluzzii allowed to mate in different ratios of sterile to untreated males have been assessed. Moreover, competitiveness was compared between males allowed one versus two days of contact with females. Sterile and untreated males four to six days of age were released in large cages (~1.75 sq m) with females of similar age at the following ratios of sterile males: untreated males: untreated virgin females: 100:100:100, 300:100:100, 500:100:100 (three replicates of each) and left for two days. Competitiveness was determined by assessing the egg hatch rate and the insemination rate, determined by dissecting recaptured females. An additional experiment was conducted with a ratio of 500:100:100 and a mating period of either one or two days. Two controls of 0:100:100 (untreated control) and 100:0:100 (sterile control) were used in each experiment. When males and females consort for two days with different ratios, a significant difference in insemination rate was observed between ratio treatments. The competitiveness index (C) of sterile males compared to controls was 0.53. The number of days of exposure to mates significantly increased the insemination rate, as did the increased number of males present in the untreated: sterile male ratio treatments, but the number of days of exposure did not have any effect on the hatch rate. The comparability of the hatch rates between experiments suggest that An. coluzzii mating competitiveness experiments in large cages could be run for one instead of two days, shortening the required length of the experiment. Sterilized males were half as competitive as untreated males, but an effective release ratio of at least five sterile for one untreated male has the potential to impact the fertility of

    A 24 year old combat medic was admitted to the field hospital at Tomislavgrad in Bosnia, with a suspected forearm, fracture. Radiographs did not show any bony injury. Clinical examination showed marked swelling and tenderness over the extensor compartment. The pain became more severe over the following 12 hours with the pain becoming most intensely felt in the extensors on passive extension. Fasciotomy for suspected acute compartment syndrome was carried out. Acute compartment syndrome is a common complication of extremity injury, and is a clinical diagnosis which should be suspected in all injuries with marked swelling and severe pain.
