    Coexistence of a mucinous cystadenoma arising in a mature cystic teratoma is infrequently reported. Herein a case of a 25-year-old woman diagnosed with a right ovarian mucinous cystadenoma arising in a mature cystic teratoma is reported. She presented with lower right abdominal discomfort. Ultrasound showed a 14.8 × 7.9 × 12.5?cm structure on the right adnexa. She underwent a diagnostic laparoscopy, which was converted to exploratory laparotomy, during which a right salpingo-oophorectomy was performed. PMID:24891964

    IMPORTANCE The Patient Protection and Affordable Care Act (PPACA) allowed young adults to remain on their parents’ insurance until 26 years of age. Reports indicate that this has expanded health coverage. OBJECTIVE To evaluate coverage, access to care, and health care use among 19- to 25-year-olds compared with 26- to 34-year-olds following PPACA implementation. DESIGN, SETTING, AND PARTICIPANTS Data from the Behavior Risk Factor Surveillance System and the National Health Interview Survey, which provide nationally representative measures of coverage, access to care, and health care use, were used to conduct the study among participants aged 19 to 25 years (young adults) and 26 to 34 years (adults) in 2009 and 2012. EXPOSURE Self-reported health insurance coverage. MAIN OUTCOMES AND MEASURES Health status, presence of a usual source of care, and ability to afford medications, dental care, or physician visits. RESULTS Health coverage increased between 2009 and 2012 for 19- to 25-year-olds (68.3% to 71.7%). Using a difference-in-differences (DID) approach, after adjustment, the likelihood of having a usual source of care decreased in both groups but more significantly for 26- to 34-year-olds (DID, 2.8%; 95% CI, 0.45 to 5.15). There was no significant change in health status for 19- to 25-year-olds compared with 26- to 34-year-olds (DID, ?0.5%; 95% CI, ?1.87 to 0.87). There was no significant change for 19- to 25-year-olds compared with 26- to 34-year-olds in the percentage who reported receiving a routine checkup in the past year (DID, 0.3%; 95% CI, ?2.25 to 2.85) or in the ability to afford prescription medications (DID, ?0.4%; 95% CI, ?2.93 to 1.93), dental care (DID, ?2.6%; 95% CI, ?5.61 to 0.61), or physician visits (DID, ?1.7%; 95% CI, ?3.66 to 0.26). There was also no change in the percentage who reported receiving a flu shot (DID, 1.9; 95% CI, ?1.93 to 4.93). Insured individuals were more likely to report having a usual source of care and a recent routine checkup and were more likely to be able to afford health care than uninsured individuals. CONCLUSIONS AND RELEVANCE Implementation of the PPACA was associated with increased health insurance coverage for 19- to 25-year-olds without significant changes in perceived health care affordability or health status. Although the likelihood of having a usual source of care declined between 2009 and 2012 for all, this decrease was smaller among 19- to 25-year-olds, and younger adults were more likely than 26- to 34-year-olds to have a usual source of care.

    A 25-year-old black man presented with left-sided chest pain and cough for 3 days. His pain was pressure-like and nonradiating and was aggravated with movement and relieved when the patient lay at a 45° angle. The patient denied fevers, chills, night sweats, and swelling but reported gaining 4 to 6 kg (10 to 15 lbs) in the past few months. His cough had started 2 weeks prior with yellow mucus production but he denied facial swelling or tenderness. He had no chronic medical conditions and was not taking medications. He had no known exposure to chemicals, fumes, or dust and no history of tobacco or alcohol abuse. PMID:25091762

    Structural evaluations were conducted on several parachute systems to determine the effects of aging on parachute materials. Most of the parachutes were 25 years old. Five 64 ft parachutes were evaluated along with one 4 ft guide surface parachute and three 16.5 ft ribbon parachutes. The parachute systems used in the study were all fabricated from nylon materials. Results were obtained for several material properties such as tensile strength, air permeability and melting point. Military specifications were used as zero-time data base due to lack of raw material data. The results indicate that over a period of about 25 years, parachute nylon materials do not degrade to unacceptable levels. 7 refs., 2 figs., 3 tabs.

  6. Physical activity attitudes, intentions and behaviour among 18–25?year olds: A mixed method study

    2012-01-01

    Background Young people (18–25?years) during the adolescence/adulthood transition are vulnerable to weight gain and notoriously hard to reach. Despite increased levels of overweight/obesity in this age group, physical activity behaviour, a major contributor to obesity, is poorly understood. The purpose of this study was to explore physical activity (PA) behaviour among 18–25?year olds with influential factors including attitudes, motivators and barriers. Methods An explanatory mixed method study design, based on health Behaviour Change Theories was used. Those at university/college and in the community, including those Not in Education, Employment or Training (NEET) were included. An initial self reported quantitative questionnaire survey underpinned by the Theory of Planned Behaviour and Social Cognitive Theory was conducted. 1313 questionnaires were analysed. Results from this were incorporated into a qualitative phase also grounded in these theories. Seven focus groups were conducted among similar young people, varying in education and socioeconomic status. Exploratory univariate analysis was followed by multi staged modelling to analyse the quantitative data. ‘Framework Analysis’ was used to analyse the focus groups. Results Only 28% of 18–25?year olds achieved recommended levels of PA which decreased with age. Self-reported overweight/obesity prevalence was 22%, increasing with age, particularly in males. Based on the statistical modelling, positive attitudes toward PA were strong predictors of physical activity associated with being physically active and less sedentary. However, strong intentions to do exercise, was not associated with actual behaviour. Interactive discussions through focus groups unravelled attitudes and barriers influencing PA behaviour. Doing PA to feel good and to enjoy themselves was more important for young people than the common assumptions of ‘winning’ and ‘pleasing others’. Further this age group saw traditional health promotion messages as ‘empty’ and ‘fear of their future health’ was not a motivating factor to change current behaviour. Conclusion 18–25?year olds are a difficult group to reach and have low levels of PA. Factors such as, ‘enjoyment’, ‘appearance ‘and ‘feeling good’ were deemed important by this specific age group. A targeted intervention incorporating these crucial elements should be developed to improve and sustain PA levels. PMID:22892291

    As a result of modern treatments, the life of women who test positive for BRCA mutations may be plotted along the arc of preventive medicine rather than the slope of diagnostics. Despite evidence supporting the benefits of risk reduction, protocols for early detection and prevention among women from families affected by hereditary breast and ovarian cancer (HBOC) are not yet proven, and clinical trials have not been undertaken for patients aged 18 to 25. The absence of psychosocial data may leave genetic counselors without uniform guidance on how to manage the care of these patients. This project sought to investigate perspectives on counseling 18-25 year-old patients from families with hereditary cancer syndromes, with specific emphasis on HBOC, given their unique developmental, familial, and medical challenges. Certified genetic counselors were recruited through the NSGC's Cancer Genetics Special Interest Group listserv. Researchers constructed an online survey which included 41 items and elicited information about: counselor demographics, training, and practice settings; approaches to cancer risk assessment; and common challenges in work with 18- to 25-year-old patients. The survey was also informed by previous work by researchers with 18 to 25-year-olds with BRCA gene mutations. Eighty-six surveys were completed. Researchers used a combination of grounded theory and content analysis for open-ended responses, supported and triangulated with statistical analysis to maximize the interpretation of data. Genetic counselors who responded to this survey experience 18-25 year old patients presenting for cancer risk assessment differently than older patients, and some reported adapting their counseling style to address these differences. Respondents differed in the extent to which they felt well-versed in the developmental needs of patients in this age group. Respondents aged 39 and under reported feeling familiar with this stage in life, having more recently completed it; respondents aged 40 and over reported they were less familiar with, and more interested in learning about, this age group. A primary challenge in cancer risk assessment of these patients, reported primarily by counselors aged 39 and under, is navigating family dynamics in counseling sessions and addressing the developmentally labile young adult. With respect to BRCA-related cancer risk, where penetrance is incomplete, onset in early adulthood is rare. Evidence-based treatment/prevention options exist, but providers may not have clarity regarding how or when to provide directive counsel. A rich understanding of the themes inherent in how people grow and change over time might enhance the counselor's capacity to assess patients and their family members. The integration of a developmental approach to genetic counseling has the potential to reduce the imperative for non-directive counseling. PMID:25011978

    Background : Young people (18–25 years) during the adolescence/adulthood transition are vulnerable to weight gain and notoriously hard to reach. Despite increased levels of overweight/obesity in this age group, diet behaviour, a major contributor to obesity, is poorly understood. The purpose of this study was to explore diet behaviour among 18–25 year olds with influential factors including attitudes, motivators and barriers. Methods: An explanatory mixed method study design, based on health Behaviour Change Theories was used. Those at University/college and in the community, including those Not in Education, Employment or Training (NEET) were included. An initial quantitative questionnaire survey underpinned by the Theory of Planned Behaviour and Social Cognitive Theory was conducted and the results from this were incorporated into the qualitative phase. Seven focus groups were conducted among similar young people, varying in education and socioeconomic status. Exploratory univariate analysis was followed by multi-staged modelling to analyse the quantitative data. ‘Framework Analysis’ was used to analyse the focus groups. Results: 1313 questionnaires were analysed. Self-reported overweight/obesity prevalence was 22%, increasing with age, particularly in males. Based on the survey, 40% of young people reported eating an adequate amount of fruits and vegetables and 59% eating regular meals, but 32% reported unhealthy snacking. Based on the statistical modelling, positive attitudes towards diet and high intention (89%), did not translate into healthy diet behaviour. From the focus group discussions, the main motivators for diet behaviour were ‘self-appearance’ and having ‘variety of food’. There were mixed opinions on ‘cost’ of food and ‘taste’. Conclusion: Elements deemed really important to young people have been identified. This mixed method study is the largest in this vulnerable and neglected group covering a wide spectrum of the community. It provides evidence base to inform tailored interventions for a healthy diet within this age group. PMID:25750826

    Background Precursor T-cell acute lymphoblastic leukemia (pre-T-ALL) may cause ocular pathologies such as cotton-wool spots, retinal hemorrhage, and less commonly, retinal detachment or leukemic infiltration of the retina itself. However, these findings are typically accompanied by the pathognomonic hematological signs of acute leukemia. Case Presentation In this case report and review of the literature, we describe a particularly unusual case of a 25-year-old man who presented to our hospital with bilateral exudative retinal detachments associated with posterior pole thickening without any hematological or neurological findings. The patient, who had a history of previously treated pre-T-ALL in complete remission, was found to have leukemia cell infiltration on retinal biopsy. Conclusion Our case underscores the fact that the ophthalmologist may be the first provider to detect the relapse of previously treated leukemia, and that ophthalmic evaluation is critical for detecting malignant ocular infiltrates.

    We report here the application of Y chromosomal DNA analysis in a retrial request case, raised officially by Sapporo High Court, Japan, of a condemned criminal whose capital punishment has been suspended. DNA was extracted from mixed seminal/vaginal secretion stains collected 25 years ago from two raped and murdered victims, and Y chromosome STR loci (DYS19, 390, 393, YCAII) were amplified and sequenced to clarify the DNA type of the rapist. Alkaline proteinase and sodium hydroxide were used before phenol/chloroform extraction to achieve high quality DNA from very old samples. In addition, amplified fragments of DYS19, DYS390, and DYS393 were sequenced using an automated DNA sequencer. Four Y STR DNA types detected from vaginal swabs were found identical to those of the accused criminal and confirmed that the two rape and murder cases had been committed by the same person. Sapporo High Court accepted the results and rejected the retrial request in February 1998. PMID:10432624

  13. 2.5-year-olds Succeed at a Verbal Anticipatory-Looking False-Belief Task

    2012-01-01

    Recent research suggests that infants and toddlers succeed at a wide range of nonelicited-response false-belief tasks (i.e., tasks that do not require children to answer a direct question about a mistaken agent’s likely behavior). However, one exception to this generalization comes from verbal anticipatory-looking tasks, which have produced inconsistent findings with toddlers. One possible explanation for these findings is that toddlers succeed when they correctly interpret the prompt as a self-addressed utterance (making the task a nonelicited-response task), but fail when they mistakenly interpret the prompt as a direct question (making the task an elicited-response task). Here, 2.5-year-old toddlers were tested in a verbal anticipatory-looking task that was designed to help them interpret the anticipatory prompt as a self-addressed utterance: the experimenter looked at the ceiling, chin in hand, during and after the prompt. Children gave evidence of false-belief understanding in this task, but failed when the experimenter looked at the child during and after the prompt. These results reinforce claims of robust continuity in early false-belief reasoning and provide additional support for the distinction between nonelicited- and elicited-response false-belief tasks. Three accounts of the discrepant results obtained with these tasks—and of early false-belief understanding more generally—are discussed. PMID:22429030

    2011-01-01

    Recent research indicates that toddlers and infants succeed at various non-verbal spontaneous-response false-belief tasks; here we asked whether toddlers would also succeed at verbal spontaneous-response false-belief tasks that imposed significant linguistic demands. 2.5-year-olds were tested using two novel tasks: a preferential-looking task in which children listened to a false-belief story while looking at a picture book (with matching and non-matching pictures), and a violation-of-expectation task in which children watched an adult “Subject” answer (correctly or incorrectly) a standard false-belief question. Positive results were obtained with both tasks, despite their linguistic demands. These results (1) support the distinction between spontaneous-and elicited-response tasks by showing that toddlers succeed at verbal false-belief tasks that do not require them to answer direct questions about agents’ false beliefs, (2) reinforce claims of robust continuity in early false-belief understanding as assessed by spontaneous-response tasks, and (3) provide researchers with new experimental tasks for exploring early false-belief understanding in neurotypical and autistic populations.

    The aim of this study was to compare safety and efficacy of bambuterol hydrochloride (10 mg) oral solution administered once daily in the evening with terbutaline sulphate (0.075 mg/kg body weight) oral solution administered three times daily in 2-5-year-old children with asthma. There were two treatment groups: (2/3) of the patients received bambuterol and (1/3) received terbutaline. The study was double-blind, randomized, and of a parallel group design, and it lasted for 3 months after a 2-week run-in period. The primary objective was to evaluate safety (adverse events, and changes in blood pressure, pulse rate, hematology, and clinical chemistry parameters). Plasma concentrations of terbutaline and/or bambuterol were also measured. Evaluation of efficacy (diary card data) was a secondary objective. A total of 155 patients (range, 2-6 years; 3 patients were 6 years old at randomization) were treated with the study drugs; 104 patients received bambuterol and 51 patients received terbutaline. Both treatments showed a good safety profile with respect to clinical and laboratory tests, and they were generally well tolerated. Reported adverse events were mild to moderate. There were no statistically significant differences between treatment groups in any of the efficacy variables (diary variables: peak expiratory flow (PEF), asthma symptoms, restlessness, other reported symptoms, use of inhaled bronchodilators, and nighttime awakenings). For morning PEF, the mean increase from run-in to treatment was 16.9 L/min in the terbutaline group and 23.3 L/min in the bambuterol group. For evening PEF, the mean increase was 20.2 L/min in the terbutaline group and 20.6 L/min in the bambuterol group. In conclusion, once-daily bambuterol is as safe and effective as terbutaline given three times daily. The study also confirmed that bambuterol has a 24-hr duration of action, and therefore its once daily administration, makes it a preferred bronchodilator agent. Pediatr Pulmonol. 2000:29:194-201.

    The aim of this study was to analyze the distribution of clusters and drug resistance of CRF01_AE among newly diagnosed, treatment-naïve HIV-infected teenagers and young adults in 3 major HIV-affected geographic regions of Guangxi Province, including the cities of Hezhou, Liuzhou, and Nanning. Samples were sequentially collected from newly diagnosed HIV-infected 16- to 25-year olds in these 3 regions from 2009 to 2013. The viral genome was extracted, and the partial pol gene was amplified and sequenced. Phylogenetic analyses were used to determine HIV-1 subtypes and CRF01_AE clusters. Transmitted drug resistance (TDR) mutations were identified using the 2009 WHO list of TDR mutations. A total of 216 sequences were obtained from CRF01_AE strains, which accounted for 83.1% of the 260 genotyped samples, of which 36 were from Hezhou, 147 from Liuzhou, and 33 in Nanning. Most (83.3%, 180/216) were from heterosexuals, followed by injection drug users (5.6%), homosexuals (4.2%), and unknown risk group (6.9%). Based on phylogenetic analyses by the maximum likelihood method, 5 distinct clusters (cluster 1-5) were identified with 213 (98.6%) sequences, whereas 3 (1.4%) sequences were ungrouped. In Hezhou, 88.9% (32/36) of CRF01_AE infections were caused by cluster 2, and 11.1% (4/36) were caused by cluster 1. In Liuzhou, 83.0% (122/147) of the CRF01_AE strains were found in cluster 1, 11.6% (17/147) from cluster 2, 1.4% (2/147) from cluster 3, 2.7% (4/147) from cluster 4, and 0.7% (1/147) from cluster 5. The distribution of CRF01_AE clusters was more even in Nanning than it was in the other 2 regions, with 18.2% (6/33) from cluster 1, 36.3% (12/33) from cluster 2, 9.1% (3/33) from cluster 3, 18.2% (6/33) from cluster 4, and 12.1% (4/33) from cluster 5. The most frequent TDR mutations were M46I (2) in the protease region and Y181C (2) from the reverse transcriptase fragment. Clusters 1 and 2 of CRF01_AE strains were prevalent in Liuzhou and Hezhou, respectively. However, multiple CRF01_AE clusters existed in Nanning. This can be partially explained by the high mobility of laborers in Nanning, the capital city of Guangxi. The prevalence of TDR was low. PMID:26020400

    Breast cancer in very young women under 40 or 35 years attracted a widespread attention. Few studies have focused on women aged below 25 years. The aim of this study was to evaluate the situation of breast cancer in women ?25 years in the center of Tunisia. Retrospective review from 1993 to 2013. Clinical, histopathological, therapeutic and outcome data were recorded. Cases were classified into different molecular subtypes based on the immunohistochemistry-based definitions. The series included 25 patients. The mean duration of symptoms was 7.5 months. The most common presenting symptom was a palpable mass. Four patients had at least one relative diagnosed with breast cancer. Mammography combined with ultrasound was suggestive of malignancy in 60 % of cases. Curative surgical treatment could be offered in 19 cases. The mean tumor size was 39 mm. Nodal metastases were detected in 9/18 cases. Twenty cases could be classified into: luminal A (5 cases), luminal B (6 cases), Her-2 (1 case), triple negative (6 cases) and unclassified (2 cases). Two women experienced locoregional recurrence and 6 had distant recurrence. Asynchronous contralateral breast cancer occurred in one case. The overall survival at 5 and 10 years was 85 and 75 % respectively. The survival was significantly lower in grade III tumors (p?=?0.04) and triple negative tumors (p?=?0.03). Breast cancer in women ?25 years is uncommon. An adequate medical education of young women and physicians is necessary. PMID:25962349

    Self-mutilation acts are known to characterize the borderline personality disorders. However, voluntary cutting of the male genital organ remains extremely rare. The present paper reports a case of a 25-years-old young male with a borderline personality. The patient committed a genital self-mutilation (GSM) targeting suicide during incarceration stage in jail. In addition, a discussion of the epidemiological and psychopathological aspects of the self-mutilation of borderline patients was been conducted. A particular interest is attributed to the genital self-mutilation and a review of the literature is presented. PMID:23914106

    Unanticipated difficult endotracheal intubations can pose challenges for the anesthesiologist. Risks include airway injury, hypoxemia, and death. There is intubation difficulty in various conditions including Downs syndrome, achondroplasia, acromegaly, and dwarfism. We describe difficulty in intubating the trachea with an appropriate sized endotracheal tube in two young male patients with hypogonadism presenting for neurosurgical procedures under general anesthesia. We discuss the role of hypogonadism and the effects of gonadotropin hormones on pubertal laryngeal growth in male patients. PMID:16301264

    Neuromyelitis optica (NMO) is a severe, idiopathic, immuno-mediated, inflammatory demyelinating disease of the central nervous system. We examined the clinical features between male and female NMO patients, for which not much data exist. One hundred and eight Chinese Han patients with NMO were analysed retrospectively, all had been detected for the aquaporin-4 (AQP4) antibody using a cell-based assay. Of 108 NMO patients, 92 were female and 16 were male (female/male?=?5.75). Ninety-four (87%) were positive for the AQP4 antibody in their serum and/or cerebral spinal fluid. Aquaporin-4 antibody-positive NMO patients had a higher female/male ratio than the negative group (P?=?0.001). Female NMO patients had a higher positive rate of the AQP4 antibody than male NMO patients (92.4 vs 56.3%, P?=?0.001). All NMO male patients were divided according to their AQP4 antibody status. 77.8% (7/9) of patients in the seropositive group had initial optic neuritis, while only one patient (14.3%, 1/7) in the negative group had optic neuritis (P?=?0.041). Limb paraesthesia was reported in only one patient in the negative group (11.1%), but it was reported in all patients in the positive group (100%) (P?=?0.001). The mean length of vertebral segments of the spinal cord lesions was 3.6?±?1.3 in the positive group, while it was 6.6?±?2.6 in the negative group (P?patients in the positive group and 85.7% of patients in the negative members (P?=?0.041). In conclusion, male NMO is rare and has a low positive rate of AQP4 antibody. PMID:26213113

    In adults, the desire for a healthy limb amputation has been reported in both the lay press and the scientific literature. While the etiology of this condition is currently unknown, prevailing theories have tended to conceptualize the phenomenon as paraphilic in origin. In this report, we present the case of a 25-year-old, nonhomosexual male-to-female transsexual who manifested an intense desire to be afflicted with a nonmutilative neurological disability (multiple sclerosis). The patient categorically denied sexual attraction towards the thought of being an amputee or physically disabled. Hypotheses are proposed for the development of this condition with special emphasis accorded to the significance of the preferred target disability. PMID:19387814

    Sexuality is an important part of healthy life. Patients with ankylosing spondylitis (AS) may be vulnerable to sexual problems because of disease activity and comorbid emotional problems. However, sexuality is a scarcely studied subject in AS. The aim of this study is to compare patients with AS with healthy control. A total of 43 male patients, who referred to the Department of Physical Medicine and Rehabilitation Clinics of the Karadeniz Technical University Farabi Hospital between May 2010 and July 2010, and were diagnosed as AS according to modified New York criteria, were included in the study. Control group consisted of healthy 43 age- and sex-matched male individuals with normal inflammatory levels. The AS patients were compared in means of sociodemographic variables and sexual function with Glombok-Rust Sexual Satisfaction Scale (GRSSS) and clinical interview. Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI) were used to determine anxiety and depression levels, respectively. The disease activity and functional conditions were evaluated with the Bath Ankylosing Spondylitis Functional Index (BASFI), the Bath Ankylosing Spondylitis Metrology Index (BASMI) and the Bath Ankylosing Spondylitis Disease Activity Index (BASDI). A total of 43 patients with AS and 43 healthy heterosexual male were included in the study. The total GRSSS score was significantly higher in patients with AS, whereas they also had significantly higher sexual complaint than healthy control. The diagnosis of sexual dysfunction according to DSM-IV was significantly higher in the patients with AS as well as depression and anxiety. In study group, GRSSS total score was modestly correlated with disease activity. The psychological status had close relation with sexual functions in AS. Overall assessment is required for complete evaluation in patients with AS. PMID:21814226

    The aim was to describe male cancer survivors' barriers towards participation in cancer rehabilitation as a means to guiding future targeted men's cancer rehabilitation. Symbolic Interactionism along with the interpretive descriptive methodology guided the study of 35 male cancer survivors representing seven cancer types. Data were generated through a 5-month fieldwork study comprising participant observations, semi-structured individual interviews and informal conversations. The analyses revealed two overarching findings shedding light on male cancer survivors' barriers to rehabilitation: 'Fear of losing control' and 'Striving for normality'. While 'Fear of losing control' signified what the men believed rehabilitation would invoke: 'Reduced manliness', 'Sympathy and dependency' and 'Confrontation with death', 'Striving for normality' was based on what the men believed rehabilitation would hinder: 'Autonomy and purpose', 'Solidarity and fellowship' and 'Forget and move on'. This study of male cancer survivors' and cancer rehabilitation documents how masculine ideals may constitute barriers for participation in rehabilitation and provides insights about why men are underrepresented in rehabilitation. The findings can guide practice to develop research-based rehabilitation approaches focused on preserving control and normality. Further empirical evidence is needed to: (1) explore the conduct of health professionals' towards male cancer patients and (2) address gender inequalities in cancer rehabilitation. PMID:26223855

    Tumoral calcinosis is an uncommon and severe complication of hemodialysis therapy. It is generally associated with the presence of the high serum calcium-and-phosphorus product. We report here a case of a patient on hemodialysis who presented with progressively increasing, multiple, tumor-like, subcutaneous swellings. These are rare manifestations of extraosseous calcification in uremic patients that are termed as tumoral calcinosis. A 25 year-old male presented with multiple, nodular, painful, cutaneous swellings all over his body that had been progressively increasing over the last four years. He was a known case of chronic glumerulonephritis who was on regular hemodialysis. The patient was investigated and diagnosed as having tumoral calcinosis and was treated with a low calcium dialysate of pure reverse osmosis water. PMID:20142918

    45,X maleness is a very rare disorder. We report on 2 new 45,X males aged 9 10/12 and 39 years, respectively. The boy presented for developmental delay, while the man was referred to us because of infertility. Both patients showed short stature (boy -2.29 SDS, man -4.05 SDS) and an unbalanced translocation of Yp, including SRY, onto the long arm of chromosome 10 and short arm of chromosome 14, respectively. The growth pattern of the 2 patients and literature data suggest the presence of a specific growth gene in the pericentrometric region of Yq. In addition, developmental delay in some 45,X males may be related to specific deletion of telomeric autosome regions, but involvement of gene(s) on the Y chromosome may play a role as well. Albeit in the boy inhibin B levels were in the normal range for age, azoospermia was demonstrated in the adult, supporting that infertility is a feature of adult 45,X men with AZFa-c deletion.

    Psychiatric interviews were conducted with 55 male Army HIV+ patients. These soldiers were diagnosed in an early stage of HIV, and were not clinically demented. Sixty-four percent were given diagnoses of a depressive disorder by a psychiatrist, while 42% self-reported depression. Fifty-five percent had a history of suicidal thoughts since their diagnosis of HIV, but only one soldier was actively suicidal. Half said that they followed a more healthy lifestyle since their diagnoses. Factors associated with a high rate of depression included being divorced, of Hispanic origin, having other medical problems, or a history of mental illness. Not telling friends and family, or feeling a lack of support from them or the military, was also significantly correlated with depression. PMID:1528468

    Objective. Thyrotoxic periodic paralysis (TPP), a known condition in Asian men, is becoming increasingly common in men from Western countries. Since suspicion for TPP as a differential in diagnosis is of utmost importance to avoid overcorrection of hypokalemia and other complications, we are reporting a case of TPP in a 25-year-old Caucasian male. Methods. The patient presented with intermittent lower extremity weakness after consumption of a large high-carbohydrate meal. Clinical examination revealed diffusely enlarged thyroid gland, no muscle power in lower extremities, tremors, and brisk deep tendon reflexes. Results. Clinical and laboratory findings were consistent with Graves' disease and the patient had hypokalemia. The patient responded to potassium repletion and was treated with propylthiouracil and propranolol. After treatment with radioactive iodine, the patient developed postablative hypothyroidism for which he was treated with levothyroxine. Conclusion. Since this condition is overlooked by physicians in Western countries, we present a case of TPP in a Caucasian male thus showing the importance of consideration of TPP in Caucasians despite its rare occurrence and the need for prompt diagnosis to avoid the danger of hyperkalemia in management of the paralytic attack in TPP patients.

    To study the relationship between antibodies detected in patients’ and/or donors’ sera and the clinical features of acute non-haemolytic transfusion reactions (ANHTRs), and to determine any gender-related difference. ANHTRs range from urticaria to transfusion-related acute lung injury (TRALI). Antibodies to human leukocyte antigen (HLA), granulocytes, platelets, and/or plasma proteins are implicated in some of the ANHTRs. A higher antibody positivity is expected for females than for males. A comparative study of ANHTRs for antibody positivity and their clinical features between females and males for both patients and donors is helpful for characterizing ANHTRs including TRALI more clearly, but such studies are few and outdated. Two hundred and twenty-three ANHTR cases reported by 45 hospitals between October 2000 and July 2005 were analysed. The patients and 196 donors of suspect blood products were screened for antibodies to HLA Class I, HLA Class II, granulocytes, and platelets. The patients were also screened for anti-plasma protein antibodies. The types and severity of ANHTR did not differ significantly between female and male patients. The frequency of the anti-HLA antibodies, but not that of the non-HLA antibodies, was significantly higher in females. Non-HLA antibodies were significantly associated with severe reactions in females. All the TRALI cases had predisposing risk factors for acute lung injury, and 60% of the cases showed anti-leucocyte antibodies. Although the anti-HLA antibodies were detected more frequently in females than males, no significant association of ANHTRs including TRALI with gender, not only for patients, but also for donors, could be shown in this study.

    A 56-year-old male patient with papillary thyroid carcinoma was given radioiodine for the treatment of persistent disease. Post radioiodine whole body scan revealed uptake at the thyroidal region and bilateral uptake at the upper thoracic region. Single photon emission computed tomography/computed tomography (SPECT/CT) confirmed uptake at the left thyroid lobe, and additional symmetrical mammary gland uptake was observed at both breasts. The patient had obesity-related gynecomastia, but he did not have any history of breast cancer, mastitis, hyperprolactinemia, or galactorrhea. Although breast uptake of radioiodine is a common finding in postpartum or lactating women, it is uncommon in male patients. To our knowledge, this is the first case of a male patient with breast uptake of radioiodine documented with SPECT/CT. SPECT/CT is useful in male patients in the differentiation of benign breast uptake with lung metastases or axillary metastases of thyroid cancer. PMID:26430322

    Sexual dysfunction impairs the quality of life of patients undergoing hemodialysis (HD). The aim of this study was to evaluate the prevalence and the nature of sexual dysfunction in a Moroccan cohort of patients with chronic renal failure (CRF) on HD. This cross-sectional study was carried out with a questionnaire in 86 patients undergoing hemodialysis. Clinical and biological investigations were done. The mean age of our patients was 46.27 +/- 15.68 years old. 81.4% of the cases suffered from a decrease in sexual activity after the onset of HD. The decrease or the loss of libido was noted in 59.3% of the cases. Total impotence was present in 22.1% of the cases and 36% reported partial impotence. Ejaculation was present in 86% of the cases. The comparison between the group of patients who had no sexual dysfunction (group I) and the group of those who had this problem (group II) showed significant differences of age, social status and sexual life before HD. Other significant differences were found regarding frequency of intercourses and sexual satisfaction. Group II was divided into 2 subgroups: IIA included patients who had sexual dysfunction before HD and IIB: those who developed it after. The comparison of this subgroups showed that differences were significant regarding age, weight and vascular risk factors (diabetes mellitus, atherosclerosis). Sildenafil was more efficient in the patients of the subgroup IIB. This study suggested that HD was one of many factors causing sexual dysfunction in hemodialysed patients. After this clinical evaluation of sexual dysfunction, we emphasize the value of a global approach of this problem. The use of sildenafil seems to be more valuable in young patients with erectile dysfunction which appeared after long dialysis duration. PMID:18209457

    Transcripts of early sessions for 7 personality-disordered male subjects participating in an ongoing naturalistic long-term dynamic psychotherapy project were rated for therapist interventions and alliance. Early transference interpretations were followed by increased defensiveness even when there was a solid alliance. Omitting transference interpretations in the face of an early negative transference was equally problematic. However, the rapid sequence of early transference and defense interpretations, or early defense interpretations alone, enhanced therapeutic work without increasing defensiveness. Caretaking of the alliance after early interpretive work was also investigated. Two different styles of handling affect emerged from the sample. PMID:11264332

    This study determined the prevalence of Helicobacter pylori infection in patients with different gastrointestinal symptoms. Two hundred and six patients were collected from outpatient clinic of medical department from March to June 2014. The age was ranged between 15 years old up to 60 years old. 76 males with mean age (33.2 ± 13.5) and 130 females with mean age (32.8 ± 14.9). All patients were submitted to full clinical examination and stool examination was performed to detect Helicobacter pylori antigen and other intestinal parasites. After getting a full history, the patient was asked specifically for history of taking non-steroidal anti-inflammatory drugs, presence of heart burn, epigastric pain, flatulence, nausea or vomiting passing black stool hematemesis and presence of other diseases. The results showed that 69.4% of the patients were positive for Helicobacter pylori antigen (143/206). The prevalence among males and females was the same (69.7%-69.2%). The prevalence among different age groups was not significant but; some-how high among age group of 15 up to 25 years old (70%). 72 patients out of 140 were associated with Co-infection with Entamaeba histolytica mainly or Giardia lamblia (51.4%). Epigastric pain and heart burn were representing about 90% of symptoms in patients with positive Helicobacter pylori antigen. Consequently, the prevalence of H. pylori infection is high in and around Tanta City in the Nile Delta (about 70%). PMID:26012224

    Patients with gout are more likely to develop most cancers than subjects without gout. Colchicine has been used for the treatment and prevention of gouty arthritis and has been reported to have an anticancer effect in vitro. However, to date no study has evaluated the relationship between colchicine use and incident cancers in patients with gout. This study enrolled male patients with gout identified in Taiwan's National Health Insurance Database for the years 1998 to 2011. Each gout patient was matched with 4 male controls by age and by month and year of first diagnosis, and was followed up until 2011. The study excluded those who were diagnosed with diabetes or any type of cancer within the year following enrollment. We calculated hazard ratio (HR), aged-adjusted standardized incidence ratio, and incidence of 1000 person-years analyses to evaluate cancer risk. A total of 24,050 male patients with gout and 76,129 male nongout controls were included. Patients with gout had a higher rate of incident all-cause cancers than controls (6.68% vs 6.43%, P?=?0.006). A total of 13,679 patients with gout were defined as having been ever-users of colchicine and 10,371 patients with gout were defined as being never-users of colchicine. Ever-users of colchicine had a significantly lower HR of incident all-cause cancers than never-users of colchicine after adjustment for age (HR?=?0.85, 95% CI?=?0.77-0.94; P?=?0.001). In conclusion, colchicine use was associated with a decreased risk of incident all-cause cancers in male Taiwanese patients with gout. PMID:26683907

    Gynecomastia is the most common abnormality of the male breast. However, breast cancer may occur, albeit with a significantly lower incidence than in females. Imaging is often used as part of the diagnosis. The aim of this study was to assess the utilization and outcome of imaging with mammography or ultrasound of the male breast in a university hospital's department of radiology. A retrospective study assessing the imaging of the male breast in 557 patients over a 10-year period. Referral was done mainly by general surgeons and general practitioners. The most common indication was enlargement of the breast, described as gynecomastia or swelling in 74% of patients, followed by pain in 24% and "lumps" in 10%. The modalities used were mammography in 65%, ultrasound in 51% and both in 26%. Most examinations, 519, were BI-RADS 1 or 2, and 38 were BI-RADS 3 or higher. Altogether 160 patients had additional fine-needle aspiration or biopsy. Malignancies were diagnosed in five patients (0.89%). Imaging had a sensitivity of 80% and a specificity of 99%. The positive predictive value was 44% and the negative predictive value 99.8%. Malignancies are rare in the male breast. The probability of finding cancer when performing imaging of clinically benign findings in the male breast is negligible. Imaging is not warranted unless there are suspicious abnormalities. Routine imaging of gynecomastia should be discouraged. PMID:25772378

    The contemporary male look includes sharp contours of the face with strong nose, significant malar-midface structure, and a powerful chin with well-defined jawline. Neurotoxins in the upper facial lines should preserve a lower position of the brows and flatter arch in men. Excessive lifting of the eyebrows and full correction of forehead and periorbital lines are not desirable. The use of dermal fillers is fully accepted into the nasolabial. Male patients with sagginess and hollowness related or not related to acquired lipodystrophies are candidates for cheek correction with volumizers. Female attractiveness lies in the cheekbones, and for men, it lies in the chin. The use of volumizers in the chin is very much appreciated by male patients, especially when it is recessed. A strong and masculine appearance is obtained by creating a square chin. Men present slight thinner lips, especially the upper one. Lip reshape in male patients is very much rejected. It requires expertise both in communication and in technical skills to convince male patients to undergo lip treatments with fillers. The use of injectables in male patients is growing. Neurotoxins in the upper facial lines and the use of dermal fillers in the nasolabial folds are widely accepted. The use of volumizers in the chin is highly appreciated. There is clear need of volumizers in the cheek to correct sagginess and hollowness in men. However, proper communication and technique are required. The same applies for the lips. Cheek and lip reshape is still considered a taboo for most patients and injectors. PMID:26441109

    Objective The nutritional status of chronic obstructive pulmonary disease (COPD) patients is associated with their exercise capacity. In the present study, we have explored the relationship between nutritional risk and exercise capacity in severe male COPD patients. Methods A total of 58 severe COPD male patients were enrolled in this study. The patients were assigned to no nutritional risk group (n=33) and nutritional risk group (n=25) according to the Nutritional Risk Screening (NRS, 2002) criteria. Blood gas analysis, conventional pulmonary function testing, and cardiopulmonary exercise testing were performed on all the patients. Results Results showed that the weight and BMI of the patients in the nutritional risk group were significantly lower than in the no nutritional risk group (P<0.05). The pulmonary diffusing capacity for carbon monoxide of the no nutritional risk group was significantly higher than that of the nutritional risk group (P<0.05). Besides, the peak VO2 (peak oxygen uptake), peak O2 pulse (peak oxygen pulse), and peak load of the nutritional risk group were significantly lower than those of the no nutritional risk group (P<0.05) and there were significantly negative correlations between the NRS score and peak VO2, peak O2 pulse, or peak load (r<0, P<0.05). Conclusion The association between exercise capacity and nutritional risk based on NRS 2002 in severe COPD male patients is supported by these results of this study. PMID:26150712

    In the literature, 51 cases of primary retroperitoneal mucinous cystadenocarcinoma have been published. We report the fourth case occurring in a male patient. The 42-year-old patient presented with multiple retroperitoneal cystic masses causing abdominal discomfort without alteration of the global clinical state. The masses were totally removed by a two-stage surgery. No other treatment has been introduced. After a follow-up of 6 months, the patient is disease-free. This rare tumor most likely arises from the mucinous metaplasia of peritoneal inclusion cysts rather than from ectopic ovarian tissue or ovarian teratomas. The occurrence of such a tumor in a male patient supports this theory. Preoperative diagnosis is mostly difficult. Clinical behavior and treatment are still controversial. PMID:19918513

    Schizophrenia is characterized by deficits in cognition as well as visual perception. There have, however, been few magnetic resonance imaging (MRI) studies of the occipital lobe as an anatomically defined region of interest in schizophrenia. To examine whether or not patients with chronic schizophrenia show occipital lobe volume abnormalities, we measured gray matter volumes for both the primary visual area (PVA) and the visual association areas (VAA) using MRI based neuroanatomical landmarks and three-dimensional information. PVA and VAA gray matter volumes were measured using high-spatial resolution MRI in 25 male patients diagnosed with chronic schizophrenia and in 28 male normal controls. Chronic schizophrenia patients showed reduced bilateral VAA gray matter volume (11%), compared with normal controls, whereas patients showed no group difference in PVA gray matter volume. These results suggest that reduced bilateral VAA may be a neurobiological substrate of some of the deficits observed in early visual processing in schizophrenia. PMID:17350226

    Background. Priapism is a pathological condition of penile erection that persists beyond, or is unrelated to, sexual stimulation. Impotence and infertility are major problems in male sickle cell disease patients, and priapism has been implicated as a cause of impotence and infertility. The aim of this study is to determine priapism prevalence and assess the knowledge of male homozygous male patients about it in Lagos, Nigeria. Methods. A cross-sectional study was conducted amongst male homozygous sickle cell disease patients of Lagos State University Teaching Hospital. Pretested questionnaires were distributed to determine the prevalence and assess their knowledge on priapism. Data were analyzed using SPSS version 16.0. Results. A total of 114 consenting subjects filled the questionnaires, 85 of 114 (74.6%) had not heard about priapism before this study. A total of 77 of 114 (67.5%) did not know that they are at risk of priapism. Whilst 84 of 114 (73.7%) were not aware that priapism is a complication of SCD. The majority, 94 of 114 (82.5%), were not aware that priapism could cause impotence. Conclusion. There is a need to create more awareness about this complication amongst sickle cell disease patients in order to stem the incidence of impotence and infertility amongst them. PMID:23956741

    Sarcopenia reportedly predicts poor outcomes in elderly patients with diffuse large B-cell lymphoma (DLBCL). However, because previous studies only involved elderly patients, it is difficult to generalize these results to all patients with DLBCL. We retrospectively analyzed 207 patients with DLBCL who received the R-CHOP or R-THP-COP regimen between June 2004 and May 2014. Sarcopenia was measured by the analysis of CT images at the L3 level before treatment. The surface of muscular tissues was selected according to the CT Hounsfield unit. This value was normalized for stature in order to calculate the L3 skeletal muscle index (L3 SMI, cm(2)/m(2)). Median age at diagnosis in the 121 males and 86 females was 67 years (range, 19-86 years). The sex-specific cutoffs for the L3 SMI were determined by receiver operator curve (ROC) analysis. Sarcopenic patients were older than non-sarcopenic patients, with a median age of 70 and 65 years, respectively (p?patients. With a median follow-up of 50.4 months, the 3-year overall survival (OS) was 70 % in the sarcopenic group and 85 % in the non-sarcopenic group (p?=?0.0260). In a subgroup analysis by gender, there was a significant difference in the OS when comparing sarcopenic and non-sarcopenic patients in males but not in females (p?=?0.0003, p?=?0.4440, respectively). Sarcopenia is an independent prognostic factor in male patients with DLBCL. PMID:26385388

    We report on five male subjects with a triad of signs compatible with Hartsfield syndrome: ectrodactyly, holoprosencephaly, and mental retardation. Only six patients with this distinctive association have been reported over the past 20 years, all of them being males. Of the patients described here, some have unreported findings such as vermian hypoplasia in one and prolonged survival into adulthood in two. Two patients developed central diabetes insipidus. All were mentally retarded. No abnormalities were found at the cytogenetic level, including array CGH in two. No known genes for holoprosencephaly or ectrodactyly were found, including GLI2. The cause of Hartsfield syndrome is unknown. An X-linked defect is possible, although no recurrences have been described to date. Our observations almost double the number of cases. They underscore the usefulness of fetal brain imaging in the differential diagnosis of syndromal clefting diagnosed in utero, particularly when ectrodactyly-ectodermal dysplasia-clefting syndrome is suspected.

    Peroral endoscopic myotomy (POEM) is a new endoscopic treatment for achalasia with very good short-term results in adults. Data about POEM in pediatric patients are missing. We present the case of a 10-year-old male patient with type I (classic) achalasia, successfully treated with POEM. The procedure was accomplished in a similar fashion to the technique used in adults. Short-term results were fine, with a complete control of dysphagia and absence of reflux. We suggest that POEM is a suitable option in pediatric patients—similar to adults—but long-term results must be awaited. PMID:26171309

    Extramammary Paget’s disease (EMPD) is a rare cutaneous neoplasm. The aim of this study was to elaborate the clinical and pathological features of Chinese EMPD male patients. The study comprised 246 patients with EMPD at our institute from January 1993 to December 2012. Scrotum was the most common initial site. The average age of onset was 63.9 years but the mean delay in diagnosis was 3.6 years. EPMD spread exclusively to the inguinal lymph nodes and the right inguinal lymph nodes are more likely to suffered Paget cells infiltration. Accompanying malignancies were found in 20 patients. Pathological examination revealed 63 patients defined as invasive EMPD. Immunohistochemical detection showed various expression levels of EMA, CEA, CK7, HER2/neu, Ki67, P53, CK20 and S100 in tumor tissues, but negative expression of VIM, LCA and HMB45. HER2/neu protein exhibited a significant association with invasive EMPD. A novel histological type of EMPD with CK7-/S100+ was identified. Elevated serum PSA level was observed in only 16% patients. Invasive EMPD often had advanced age of onset. Metastatic EMPD showed significantly shorter in the delay in diagnosis and the greater length of skin lesion in contrast to others. This study demonstrates the clinical and pathological features of Chinese male EMPD patients, and may provide implications for the management of Chinese EMPD patients. PMID:26722523

    Male accessory gland inflammation or infection (MAGI) is a potentially underdiagnosed complication of type 2 diabetes (DM2); specifically, we reported in a recent study that the frequency of MAGI was 43% among DM2 patients. In previous studies, we have demonstrated that diabetic autonomic neuropathy (DAN) is associated with a peculiar ultrasound characterization of the seminal vesicles (SVs) in DM2 patients. The aim of the present study was to evaluate the frequency of MAGI in two different categories of DM2 patients (i.e. patients with and without symptoms that possibly reflect DAN) and the respective ultrasound characterizations. Sixty DM2 patients with a mean (± s.e.m.) age of 42.0 ± 6.0 years (range: 34–47 years) were classified according to the presence or the absence of symptoms that could possibly reflect DAN (group A: DM2 with symptoms possibly reflecting DAN, n = 28 patients and group B: DM2 without symptoms possibly reflecting DAN, n = 32 patients). The patients in Group A exhibited a significantly higher frequency of MAGI compared with those in group B patients (P < 0.05); moreover, the Group A patients exhibited a significantly higher frequency of ultrasound signs suggestive of vesiculitis (P < 0.05). Finally, the concentrations of lymphocytes but not the concentrations of the leukocytes in the semen were significantly higher (P < 0.05) in group A compared with group B. PMID:24799635

    In 1765 Giovanni Morgagni described a syndrome consisting of hyperostosis frontalis interna (HFI), obesity and hirsutism. In 1928 Stewart and in 1930 Morel added neuropsychiatric symptoms, e.g. depression and dementia, which led to the definition of the Morgagni-Stewart-Morel Syndrome (MSM). Although mostly women were characterized in literature no gender specifity is demanded. This case report presents the rare case of a 66 year old male psychiatric patient with Morgagni-Stewart-Morel Syndrome. The patient complained of loss of concentration and difficulties with activities of daily living. Admission diagnosis was an opioid misuse on the basis of a chronic pain syndrome. In this case report we are describing clinical features, the patient history and technical (MRI) and neuropsychological tests. Although severe psychiatric symptoms and neuropsychological deficits are commonly seen in these patients, our patient showed only mild symptoms. This case reports shows the possibility of a male patient with MSM. If MSM is a separate entity or just an epiphenomena of hormone dysregulation should be investigated in further studies.

    Primary gallbladder lymphoma, although rare, usually presents in females with symptoms mimicking cholecystitis. We present a rare case of primary gallbladder in an 81-year-old male with no risk factors whose only symptom was weight loss. Routine blood tests including liver function tests were unremarkable. A CT colonography was carried out to exclude colonic malignancy. Unilateral gallbladder wall thickening and lymphadenopathy were incidentally detected and confirmed by ultrasound and a decision for the patient to undergo laparoscopic cholecystectomy and intraoperative cholangiogram was made. Histology confirmed extranodal marginal zone lymphoma with follow-up staging and biopsy of the bone marrow not demonstrating spread. Cholecystectomy was therefore deemed curative and no adjuvant therapy was necessary. Thickening of the gallbladder wall on any imaging with or without symptoms should not be ignored or assumed to be cholecystitis, even in males with no risk factors. In these patients urgent cholecystectomy with intraoperative cholangiogram is indicated with histology and haematology follow-up. PMID:26587306

    Non-Hodgkin lymphoma (NHL) of the breast is a rare disease. Herein, we report a rare case of secondary involvement of the breast by NHL in a male patient and the ultrasound imaging findings. A 70-year-old man noticed an induration of the subareolar region of the right breast. He had been diagnosed as having mantle cell lymphoma 5 years before and treated with several series of chemoradiotherapy. On supine examination, palpation revealed bilateral breast enlargement, but detection of a lump was difficult. Ultrasonography showed a hypoechoic non-mass image-forming lesion in the subareolar region of the right breast. The final pathological diagnosis was recurrence of mantle cell lymphoma in the right breast. The diagnosis of malignant lymphoma of the breast by imaging modalities is difficult because there are no specific features. Breast lymphoma should be included with gynecomastia and breast cancer in the differential diagnosis of male patients with breast enlargement. PMID:22396322

    Male breast cancer is a rare malignant disease characterized by hormonal imbalance. Hepatocellular carcinoma (HCC) is the most common neoplasm of the liver, and is generally correlated with hepatitis B or C virus-related cirrhosis. While to our knowledge a case with these two malignant diseases in a same male patient in the concomitant period is an exceptional event, rarely reported in literature. In this report, we present a case in which a Chinese patient with hepatitis B developed a tumor mass that originated from segment V of the liver and presented with right breast nodules at the same time. Synchronous mastectomy and hepatectomy were performed, and standard endocrine therapy and chemotherapy as adjuvant treatment were therefore followed. The diverse histogenesis of the two kinds of cancers highlights the need for us to investigate any common physiopathogenetic elements. PMID:26617917

    Proliferation activity has already been established as a prognostic marker or as a marker for anticancer drug sensitivity. In gastric cancer, however, the prognostic significance of proliferation activity is still being debated. Several studies evaluating proliferation activity using Ki-67 have shown controversial results in terms of the relationship between proliferation activity and overall survival (OS) or drug sensitivity in gastric cancer patients. Because cytoskeleton-associated protein 2 (CKAP2) staining has recently been introduced as a marker of proliferation activity, we analyzed 437 gastric cancer tissues through CKAP2 immunohistochemistry, and we evaluated the chromatin CKAP2-positive cell count (CPCC) for proliferation activity. Although the CPCC did not show any significant correlation with OS in the male, female or total number of cases, it did show a significant correlation in the T1 or T2 male patient subgroup, according to log-rank tests (P=0.001) and univariate analysis (P=0.045). Additionally, multivariate analysis with the Cox proportional hazard regression model showed a significant correlation between the CPCC and OS (P=0.039) for the co-variables of age, gender, T stage, N stage, histology, tumor location, tumor size and adjuvant chemotherapy. In male gastric cancer cell lines, faster-growing cancer cells showed higher sensitivity to cisplatin than slow-growing cells. Thus our study indicates that CPCC-measured proliferation activity demonstrates a significantly worse prognosis in T1 or T2 male gastric cancer patients. The CPCC will help to more precisely classify gastric cancer patients and to select excellent candidates for adjuvant chemotherapy, which in turn will facilitate further clinical chemotherapeutic trials.

    From 1980 to July 1997 sixty-one male-to-female gender transformation surgeries were performed at our university center by one author (A.M.). Data were collected from patients who had surgery up to 1994 (n = 47) to obtain a minimum follow-up of 3 years; 28 patients were contacted. A mail questionnaire was supplemented by personal interviews with 11 patients and telephone interviews with remaining patients to obtain and clarify additional information. Physical and functional results of surgery were judged to be good, with few patients requiring additional corrective surgery. General satisfaction was expressed over the quality of cosmetic (normal appearing genitalia) and functional (ability to perceive orgasm) results. Follow-up showed satisfied who believed they had normal appearing genitalia and the ability to experience orgasm. Most patients were able to return to their jobs and live a more satisfactory social and personal life. One significant outcome was the importance of proper preparation of patients for surgery and especially the need for additional postoperative psychotherapy. None of the patients regretted having had surgery. However, some were, to a degree, disappointed because of difficulties experienced postoperatively in adjusting satisfactorily as women both in their relationships with men and in living their lives generally as women. Findings of this study make a strong case for making a change in the Harry Benjamin Standards of Care to include a period of postoperative psychotherapy. PMID:10097806

    Background Androgenetic alopecia (AGA) is a common hair loss disease with genetic predisposition among men and women, and it may commence at any age after puberty. It may significantly affect a variety of psychological and social aspects of one's life and the individual's overall quality of life (QoL). Objective This study aimed to investigate the QoL of AGA patients and discover the factors that can influence the QoL of AGA patients, including previous experience in non-medical hair care, reasons for hospital visits, age, duration, and the severity of AGA. Methods A total of 998 male patients with AGA were interviewed, using the Hair Specific Skindex-29 to evaluate the QoL of AGA patients. Results The results of the Hair Specific Skindex-29 on patients with AGA were as follows: symptom scale: 26.3±19.5, function scale: 24.0±20.1, emotion scale: 32.1±21.8, and global score: 27.3±19.1. According to this assessment, QoL was more damaged if the patient had severe alopecia, a longer duration of AGA, younger age, had received previous non-medical hair care, and visited the hospital for AGA treatment. Conclusion This study showed that AGA could harmfully affect the patients' QoL. These findings indicate that dermatologists should address these QoL issues when treating patients with alopecia.

    Purpose: Recent studies have reported fluctuations in sex hormones during pelvic irradiation. The objective of this study was to observe the effects of radiation on hormonal profiles for two treatment modalities: conventional external beam radiotherapy (EBRT) and high-dose-rate brachytherapy (HDRBT) given neoadjuvantly for patients with rectal cancer. Methods and Materials: Routine serum follicle stimulating hormone (FSH), luteinizing hormone (LH), and testosterone levels were collected from 119 consecutive male patients receiving either EBRT, using 45.0-50.4 Gy in 25-28 fractions with concurrent 5-fluorouracil chemotherapy or HDRBT using 26 Gy in 4 fractions. Results: Thirty patients with initially abnormal profiles were excluded. Profiles included in this study were collected from 51 patients treated with EBRT and 38 patients treated with HDRBT, all of whom had normal hormonal profiles before treatment. Mean follow-up times were 17 months for the entire patient cohort-14 and 20 months, respectively-for the EBRT and HDRBT arms. Dosimetry results revealed a mean cumulative testicular dose of 1.24 Gy received in EBRT patients compared with 0.27 Gy in the HDRBT group. After treatment, FSH and LH were elevated in all patients but were more pronounced in the EBRT group. The testosterone-to-LH ratio was significantly lower (p = 0.0036) in EBRT patients for tumors in the lower third of the rectum. The 2-year hypogonadism rate observed was 2.6% for HDRBT compared with 17.6% for EBRT (p = 0.09) for tumors in the lower two thirds of the rectum. Conclusion: HDRBT allows better hormonal sparing than EBRT during neoadjuvant treatment of patients with rectal cancer.

    Fungus is one of the causes of chronic rhinosinusitis. If the fungus occupies the sinus but does not invade the sinonasal mucosa, this is called sinus fungus ball. Any association between anatomical variations and fungus ball remains unclear. Sinus fungus ball is defined as non-invasive chronic fungal rhinosinusitis occurring in immunocompetent patients, and the maxillary sinus is the most commonly affected. The etiology of maxillary sinus fungus ball remains unclear. This study assessed the potential contribution of anatomical variations, such as deviated nasal septum, concha bullosa, and Haller cell to the development of fungus ball in the maxillary sinus. Concha bullosa and Haller cell are structural variations that narrow the nasal airflow passage and contribute to chronic rhinosinusitis. The involvement of these variations has been investigated in chronic sinusitis but not in sinus fungus ball. Preoperative computed tomography findings of 103 patients with maxillary sinus fungus ball were evaluated retrospectively. Septal deviation and Haller cell were not correlated with the side of maxillary sinus fungus ball. Concha bullosa was more common on the unaffected side (p = 0.099). When we analyzed males and females separately, maxillary sinus fungus ball was more common on the concave side of the deviated septum in only male patients (p = 0.006). The high incidence of maxillary fungus ball in the concave side may reflect the consequences of the traumatic effects caused by wall shear stress of the high-velocity airflow and the increased chance of inhaling fungus spores.

    The purpose of this study was to examine the physiological responses to treadmill and cycle cardiopulmonary exercise testing (CPET) in male and female COPD patients. Fifty-five patients [28 males (FEV1=58.2±19.5% predicted), and 27 females (FEV1=65.3±16.6% predicted)] completed a treadmill and a cycle CPET in random order on two separate days. Respiratory and cardiovascular data were obtained. Compared to the cycle CPET, the treadmill elicited greater peak power output and peak oxygen uptake, while arterial saturation at peak exercise was lower with the treadmill; however, there were no differences between the responses in men and women. No differences were observed in heart rate, ventilation, tidal volume/breathing frequency, inspiratory capacity, or dyspnea responses between modalities or sex. The physiological responses between treadmill and cycle CPET protocols are largely similar for both men and women with COPD, indicating that either modality can be used in mild/moderate COPD patients.

    With the availability of a potential treatment to reverse male hypogonadism (MH), the primary aim of this case series study was to determine independent relationships between this condition and the nutritional, functional, and quality of life characteristics of advanced cancer patients (ACP). Free testosterone levels were measured in 100 male patients with advanced lung and gastrointestinal (GI) cancer. Routine blood markers of nutrition and inflammation, self-reporting questionnaires for symptom, nutrition, and functional status along with handgrip dynamometry were assessed for all patients at bedside. Almost half of this cohort underwent further assessments (body composition, lower body strength, in depth quality of life and fatigue questionnaires) at the McGill Nutrition and Performance Laboratory (mnupal.mcgill.ca). Multiple regression analyses were performed to identify independent correlations between free testosterone and the above measures. Seventy-six percent of patients were diagnosed with MH. Using multiple linear regression, low free testosterone (31.2 pmol/L) was independently associated with lower albumin (B = –3.8 g/L; 95% confidence interval CI –6.8:–0.8), muscle strength (–11.7 lbs; –20.4: –3.0) and mass in upper limbs (–0.8 kg; –1.4: –0.1), overall performance status (Eastern Cooperative Oncology Group Performance Scale, ECOG PS 0.6; 0.1:1.1), cancer-related fatigue (Brief Fatigue Inventory, BFI 16.7; 2.0: 31.3), and overall quality of life (MQoL total score –1.42; –2.5: –0.3). Thus MH seems to be highly prevalent in ACP, and it is independently associated with important nutritional, functional, and quality of life characteristics in this patient population. PMID:26316882

  2. Exercise increases serum endostatin levels in female and male patients with diabetes and controls

    PubMed Central

    2014-01-01

    Background Type 2 diabetes mellitus (T2DM) is often associated with atherosclerotic changes in coronary vessels, most notably plaques. The angiostatic parameter endostatin is able to inhibit angiogenesis in tissue as well as in plaques and therefore plays an important role in physiological and pathological neovascularisation. The aim of the present study was to investigate sex-specific differences and the influence of exercise on circulating endostatin levels in patients suffering from diabetes, and control subjects. Methods In total, 42 T2DM-patients and 45 control subjects were investigated. They underwent a graded physical stress test (ergometry). Serum endostatin levels were measured in venous blood at rest and directly after reaching maximum workload. Results Females showed significantly higher endostatin levels at baseline measurements compared to men, independently of their underlying disease. In both female and male T2DM-patients endostatin levels were significantly lower compared to controls. Both groups and sexes showed a significant increase of endostatin after physical stress, whereas the extent of endostatin-increase was between 10.59-15.05%. Conclusion Middle-aged healthy female individuals as well as female T2DM-patients showed higher circulating serum endostatin levels compared to males, suggesting a hormonal influence on baseline circulating endostatin amounts. Exercise-induced increase in endostatin is also observable in patients suffering from T2DM. Concerning vascularisation, lower endostatin levels in T2DM might be advantageous. Concerning plaque stability, lower levels might be prejudicial. Trial registration Clinical Trial Registration-URL: http://clinicaltrials.gov/ct2/results?term=NCT01165515 PMID:24393402

    Based on computer EEG (CEEG) profiles, in high doses, antidepressant properties of mesterolone, a synthetic androgen, were predicted. In a double-blind placebo controlled study, the clinical effects of 300-450 mg daily mesterolone were investigated in 52 relatively young (age range 26-53 years, mean 42.7 years) male depressed outpatients. During 6 weeks of mesterolone treatment, there was a significant improvement of depressive symptomatology. However, since an improvement was also established during the placebo treatment, no statistically appreciable difference in the therapeutic effects of mesterolone was established compared to placebo. Mesterolone treatment significantly decreased both plasma testosterone and protein bound testosterone levels. Patients with high testosterone levels prior to treatment seem to have had more benefit from mesterolone treatment than patients with low testosterone levels. The degree of improvement weakly correlated to the decrease of testosterone levels during mesterolone treatment. PMID:6431212

    Only a limited number of orthopedic oncologists make arrangements for pre-chemotherapy fertility preservation, such as sperm cryopreservation, for their patients. The purpose of this study was to offer fertility preservation to male patients with high-grade malignant bone and soft tissue tumors and assess the outcomes. The study included 14 male patients, aged <45 years, with high-grade bone and soft tissue tumors. The median age at diagnosis was 23.0±12.0 years (range, 8-42 years). Following pathological confirmation of high-grade malignant tumor, we informed all the patients and/or their guardians on the issue of chemotherapy-related male infertility. If the patients were interested in preserving fertility, they were referred to a team of reproductive specialists. We documented the patients' clinical characteristics and techniques used for fertility preservation. The majority of unmarried and childless patients were interested in fertility preservation. Four patients (28.5%) selected sperm cryopreservation and 1 patient (7.1%) selected hemi-testicular preservation, as he had developed erectile dysfunction following previous surgery for colon cancer. Married patients and those with children did not wish to preserve fertility. In conclusion, infertility following chemotherapy raises serious concerns for young male patients with high-grade bone and soft tissue tumors. Prior to initiating chemotherapy, the potential risks of chemotherapy should be explained, counseling should be provided and informed consent should be obtained from the patients, ideally without delaying commencement of cancer treatment. Prior to administering cancer chemotherapy, orthopedic oncologists are encouraged to offer sperm banking to young male patients at risk of infertility. PMID:25279207

    Benign multicystic peritoneal mesothelioma (BMPM) is a rare peritoneal tumor. Surgery is the only effective treatment for BMPM, and affected tissues occasionally must be sacrificed to achieve adequate debulking. A 25-year-old female was diagnosed with BMPM. She was counseled on fertility preservation and had oocyte cryopreservation prior to her debulking. Fertility preservation through embryo or oocyte cryopreservation is a valuable option for patients at risk of losing reproductive tissues during extensive surgery and chemotherapy. PMID:24861198

    Context. Breast cancer (BC) in men is a rare condition, corresponding to 1% of all neoplasms in this gender. Some studies show that up to 93% of BC cases in men are advanced disease. If its occurrence constitutes an uncommon fact, the appearance of a metastasis to the central nervous system (CNS) is extremely rare. The objective of the present study is to present the case of a male patient, bearer of HIV infection, who presented with BC and later metastasis to the CNS. We also include a brief review of the literature. Case Report. We describe a case of a male patient, 59 years old, with HIV infection and a history of BC treated 4 years earlier, which progressed into headache and vertigo. Neuroimaging exams showed lesions suggestive of cerebral metastasis and a stereotaxic biopsy confirmed BC metastasis. Conclusion. Breast cancer in men with metastasis to the CNS is a rare condition and similar reports were not found in the available databases. It should be pointed out that even though rare, it should be considered among the differential diagnoses for SNC metastases in men, although HIV infection favors the appearance of some types of cancer.

    2015-01-01

    Background: Surgeons performing an ilioinguinal exposure for acetabular fracture surgery need to be aware of aberrant findings such as inguinal hernias and spermatic cord lesions. The purpose of this study is to report these occurrences in a clinical series of adult males undergoing acetabular fracture fixation and a series of adult male cadavers. The secondary aim is to characterize these abnormalities to aid surgeons in detecting these abnormalities preoperatively and coordinating a surgical plan with a general surgeon. Methods: Clinical study- Retrospective review of treated acetabular fractures through an ilioinguinal approach. Incidence of inguinal canal and spermatic cord abnormalities requiring general surgery consultation were identified. Corresponding CT scans were reviewed and radiographic characteristics of the spermatic cord abnormalities and/or hernias were noted. Cadaveric study- 18 male cadavers dissected bilaterally using an ilioinguinal exposure. The inguinal canal and the contents of the spermatic cord were identified and characterized. Results: Clinical Study- 5.7% (5/87) of patients had spermatic cord lesion and/or inguinal hernia requiring general surgical intervention. Preoperative pelvic CT scan review identified abnormalities noted intraoperatively in four of the five patients. Cord lipomas visualized as enlargements of the spermatic cord with homogeneous density. Hernias visualized as enlarged spermatic cords with heterogeneous density. Cadaver Study- 31% (11/36) of cadavers studied had spermatic cord and/or inguinal canal abnormalities. Average cord diameter in those with abnormalities was 24.9 mm (15-28) compared to 16 mm (11-22) in normal cords, which was statistically significant. Discussion: The clinical and cadaveric findings emphasize the importance of understanding inguinal abnormalities and the value of detecting them preoperatively. The preoperative pelvic CT scans were highly sensitive in detecting inguinal abnormalities. PMID:26550593

    Background. BRCAPRO is a risk assessment model to estimate the risk of carrying a BRCA mutation. BRCA mutation carriers are at higher risk of developing breast, ovarian, pancreatic, and prostate cancer. BRCAPRO was developed for women and found to be superior to other risk assessment models. The present study evaluated the validity of BRCAPRO at predicting the risk of male patients carrying a BRCA mutation. Patients and Methods. A total of 146 men who presented for genetic counseling and testing from February1997 to September 2011, and their test results were included in the present study. BRCAPRO risk assessment for all patients was calculated using the BRCAPRO clinical CancerGene assessment software. Results. The mean age at presentation was 57 years. Of the 146 patients, 48 had breast cancer, 18 had pancreatic cancer, 39 had prostate cancer, 27 had other primary cancers, and 37 had no cancer. Fifty patients (34%) tested positive for a BRCA mutation (22 BRCA1, 27 BRCA2, and 1 BRCA1 and BRCA2). The mean BRCAPRO score for all patients was 24.96%. The BRCAPRO score was significantly higher for patients who tested positive for a BRCA mutation (46.19% vs. 13.9%, p < .01). The area under the receiver operating characteristics curve was 0.83 for all patients for the BRCAPRO score to predict the risk of carrying a BRCA mutation. At a cutoff point of 30.02%, the sensitivity, specificity, positive predictive value, and negative predictive value were 0.74, 0.81, 0.67, and 0.86, respectively. Conclusion. BRCAPRO appears to be a valid risk assessment tool for determining the risk of carrying a BRCA mutation in men. Implications for Practice: Men carrying genetic mutations in the BRCA gene have a greater risk than the general population of developing certain types of cancer, including breast, pancreatic, and prostate cancer. BRCAPRO is a risk assessment model that predicts the risk of carrying a BRCA mutation. The present study aimed at validating BRCAPRO for use with men seen for genetic counseling, whether affected by cancer or not. The data available for 146 patients revealed that BRCAPRO was effective at identifying patients at risk of BRCA mutation. These findings could help in identifying a subset of high-risk patients who should proceed to genetic testing. PMID:25948675

    Serotonin (5-HT)2C receptors in brain affect psychosis, reward, substance abuse, anxiety, other behaviors, appetite, body temperature, and other physiological measures. They also have been implicated in antipsychotic drug efficacy and side effects. We previously reported that the hyperthermia following administration of MK-212, a predominantly 5-HT(2C) receptor agonist, was diminished in a small sample of patients with schizophrenia (SCH), suggesting decreased 5-HT(2C) receptor responsiveness. We have now studied the responses to oral MK-212 and placebo in a larger sample of unmedicated male SCH (n = 69) and normal controls (CON) (n = 33), and assessed the influence of comorbid substance abuse (SA) on oral body temperature, behavioral responses, etc. The placebo-adjusted oral body temperature response to MK-212 was significantly lower in SCH compared to CON and not significantly different between the SCH with or without SA. Some behavioral responses to MK-212, e.g. self-rated feelings of increased anxiety, depression and decreased calmness, or good overall feeling, were significantly lower in the SCH patients compared to CON. These results add to the evidence for diminished 5-HT(2C) receptor responsiveness in SCH patients compared to CON and are consistent with reported association of HTR(2C) polymorphisms, leading to decreased expression or function of the HTR(2C) in patients with SCH.

    Background: Primary spontaneous pneumothorax (PSP) is usually seen in young male smokers. Pathophysiology of PSP remains unclear, and studies concerning emotional status are scarce. The aim of this study is to investigate psychological factors associated with primary spontaneous pneumothorax. Methods: The Beck Depression Inventory, Beck Anxiety Inventory, State-Trait Anger Expression Inventory, and State-Trait Anxiety Inventory were administered. Results: A total of 40 patients and 40 healthy controls were included in this study. The mean age in the patient group was 24.60 years, while that in the control group was 26.45 years. The difference was not significant. The weight and body mass index of the patient group were significantly lower compared to those of the control group. The mean Beck Anxiety Inventory scores in the patient and control groups were 10.37 ± 11.34 and 8.25 ± 10.60, respectively. Anxiety levels did not differ between the groups (p = 0.389). The mean Beck Depression Inventory scores of the patient and control groups were 8.20 ± 8.37 and 6.80 ± 7.57, respectively, but the difference was not significant (p = 0.435). When the anger structures of the groups were compared, no difference was found in any sub-scale. Trait anxiety scores were higher in the patient group compared to those in the control group, but the difference was not significant (p = 0.369). Conclusions: This study’s findings indicated that anger, anxiety, and depression levels did not differ between the primary spontaneous pneumothorax and healthy groups. PMID:24955190

    Background Little is known about physicians’ human papillomavirus (HPV) vaccine recommendations for males while the Advisory Committee on Immunization Practices’ (ACIP) permissive guidelines for male vaccination were in effect. The purpose of this study was to examine and explore factors associated with U.S. physicians’ HPV vaccine recommendations to early (ages 11–12), middle (13–17), and late adolescent/young adult (18–26) males. Methods Nationally representative samples of family physicians and pediatricians were selected in 2011 (n=1,219). Physicians reported the frequency with which they recommended HPV vaccine to male patients (“always” [>75% of the time] vs. other) for each age group. Statistically significant predictors of vaccine recommendation were identified using multivariable logistic regression. Results The prevalence of physicians reporting they “always” recommended HPV vaccination for males was 10.8% for ages 11–12, 12.9% for ages 13–17, and 13.2% for ages 18–26. Pediatrician specialty and self-reported early adoption of new vaccines were significantly associated with recommendation for all patient age groups. Additionally, physician race and patient payment method were associated with physician recommendations to patients ages 11–12, and patient race was associated with recommendations to ages 13–17 and 18–26. Conclusions Less than 15% of physicians surveyed reported “always” recommending HPV vaccine to male patients following national guidelines for permissive vaccination. Vaccine financing may have affected physicians’ vaccine recommendations. Impact If these recommendation practices continue following the ACIP’s routine recommendation for males in October 2011, then interventions designed to increase recommendations should target family physicians and possibly utilize early adopters to encourage support of HPV vaccination guidelines.

  14. Patient-specific FDG dosimetry for adult males, adult females, and very low birth weight infants

    NASA Astrophysics Data System (ADS)

    Niven, Erin

    Fluorodeoxyglucose is the most commonly used radiopharmaceutical in Positron Emission Tomography, with applications in neurology, cardiology, and oncology. Despite its routine use worldwide, the radiation absorbed dose estimates from FDG have been based primarily on data obtained from two dogs studied in 1977 and 11 adults (most likely males) studied in 1982. In addition, the dose estimates calculated for FDG have been centered on the adult male, with little or no mention of variations in the dose estimates due to sex, age, height, weight, nationality, diet, or pathological condition. Through an extensive investigation into the Medical Internal Radiation Dose schema for calculating absorbed doses, I have developed a simple patient-specific equation; this equation incorporates the parameters necessary for alterations to the mathematical values of the human model to produce an estimate more representative of the individual under consideration. I have used this method to determine the range of absorbed doses to FDG from the collection of a large quantity of biological data obtained in adult males, adult females, and very low birth weight infants. Therefore, a more accurate quantification of the dose to humans from FDG has been completed. My results show that per unit administered activity, the absorbed dose from FDG is higher for infants compared to adults, and the dose for adult women is higher than for adult men. Given an injected activity of approximately 3.7 MBq kg-1, the doses for adult men, adult women, and full-term newborns would be on the order of 5.5, 7.1, and 2.8 mSv, respectively. These absorbed doses are comparable to the doses received from other nuclear medicine procedures.

    Alström syndrome is a rare disorder typified by early childhood obesity, neurosensory deficits, cardiomyopathy, progressive renal and hepatic dysfunction, and endocrinological features such as severe insulin resistance, type 2 diabetes, hyperlipidemia, and hypogonadism. Widespread fibrosis leads to multiple organ failure. Mutations in ALMS1 cause Alström’s syndrome. Two age-matched, unrelated adolescent males of Serbian descent with Alström syndrome underwent an extensive workup of blood chemistries, and ophthalmological, audiological, and genetic evaluations. Although both showed typical features of Alström syndrome in childhood, several differences were observed that have not been reported previously. Patient 1 was first studied at the age of 13 years for multisystemic disease and re-evaluated at the age of 15.5 years. Patient 2 is a 15-year-old boy who presented at birth with epilepsy and psychomotor developmental delay and generalized tonic–clonic seizures with severe cognitive impairment, features not documented previously in this syndrome. Sequencing analysis indicated two novel ALMS1 mutations in exon 8: p.E1055GfsX4 and p.T1386NfsX15. Metabolic and physiological similarities were observed in both patients, including severe insulin resistance, and truncal obesity with fat loss suggestive of partial lipodystrophy, supporting evidence for a role for ALMS1 in adipose tissue function. The unusual phenotypes of clonic–tonic seizures and severe cognitive abnormalities and lipodystrophy-like adiposity pattern have not been documented previously in Alström syndrome and may be an under-reported abnormality.

    Dopamine plays an important role in the development of alcohol dependence, cognitive dysfunction, and is regulated via dopamine transporter activity. Although dopamine transporter activity is critically involved in alcohol dependence, studies observing this relationship are limited. Thus the current study examined whether dopamine transporter availability is associated with developing of alcohol dependence and cognitive dysfunction. Brain imaging with 99mTc-TRODAT-1 as a ligand was used to measure dopamine transporter availability among 26 male patients with pure alcohol dependence and 22 age- and sex- matched healthy volunteers. The Wisconsin Card Sorting Test (WCST) and Tridimensional Personality Questionnaire (TPQ) were administered to assess neurocognitive functioning and personality traits, respectively. Compared to healthy controls, patients with alcohol dependence showed a significant reduction in dopamine transporter availability (p < 0.001), as well as diminished performance on the WCST (p < 0.001). Dopamine transporter availability was negatively correlated with both total and perseverative WCST errors among healthy controls, but only patients with alcohol dependence showed a positive correlation between dopamine transporter availability and a harm avoidance personality profile. Thus, reductions in dopamine transporter availability may play a pathophysiological role in the development of pure alcohol dependence, given its association with neurocognitive deficits. Moreover, personality may influence the development of pure alcohol dependence; however, additional clinical subgroups should be examined to confirm this possibility. PMID:26120847

    Although aesthetic procedures are known to have a higher impact on women, men are becoming more inclined toward such procedures since the last decade. To determine the reason behind the increase in demand for male aesthetic procedures and to learn about the expectations and inquietude related to body contouring surgery, a prospective questionnaire study was conducted on 200 Turkish males from January 1, 2011-May 31, 2012. Demographic information, previous aesthetic procedures and thoughts on body contouring procedures with given reasons were questioned. The results of the study showed that 53 % of all participants considered undergoing body contouring surgery with the given reason that they believed their current body structure required it. For those who did not consider contouring operations, 92.5 % said they felt that they did not need such a procedure. The results of the statistical analysis showed that BMI was a significant factor in the decision making process for wanting to undergo body contouring procedures. The results of the study showed that men's consideration for aesthetic operations depends mainly on necessity and that the most considered region was the abdominal zone in regard to contouring. We can conclude that men are becoming more interested in body contouring operations and therefore different surgical procedures should be refined and re-defined according to the expectations of this new patient group.

    This systematic review assesses weight loss interventions in young adults (18-25 years), who are vulnerable to weight gain. This age group experience critical life course points (leaving home for higher studies or job, pregnancy, cohabitation) and develop/establish lifestyle and behavioural patterns making this an opportune intervention period. Medline, Embase, Cinahl, PsychINFO and Cochrane Library were searched (1980 to March 2008). All trials and cohort studies with control groups that assessed weight loss interventions in this specific age group were included finally identifying 14 studies. Before and after comparison of behavioural/motivational interventions (-2.40 kg; 95% CI -5.4 to 0.6) and combination interventions (-2.96; 95% CI -4.4 to -1.5) consistently showed weight loss. Behavioural/motivational interventions increased self-efficacy, the desire to control weight, boosted self-esteem, and increased satisfaction with body areas and appearance. Interventions also showed improvements in HDL cholesterol, insulin, glucose and maximum oxygen uptake. However, recruitment to participation in interventions was a barrier for this age group with small sample sizes and short-term interventions. There may be gender differences in preference to participation in certain type of interventions. Further research to understand attitudes towards healthy lifestyle and preferences of interventions is needed to develop suitable interventions for this vulnerable age group. PMID:19874531

    Abstract Purpose: To assess the impact of listening to preferred music on relieving male patients' pain and anxiety during flexible cystoscopy. Patients and Methods: A total of 124 male patients were admitted to our hospital for flexile cystoscopy by a single urologist between January 2013 and September 2013 and randomized to two equal groups. Group 2 included 62 patients who could select and listen to their preferred music during flexible cystoscopy. Group 1 included 62 patients who were unable to listen to the music. All patients were administered the same amount of lidocaine (10?mL) for 3 minutes for local anesthesia before flexible cystoscopy. A visual analog scale (VAS) ranging from 0 to 10 was used to assess patients' pain feeling after the cystoscopy procedure. Anxiety levels were calculated according to the State Instrument of State-Trait Anxiety Inventory (STAI-S), and the pulse rate were recorded 5 minutes before and immediately after the procedure. The duration of the procedure of each group were also analyzed. Results: Statistically significant differences were detected between group 1 and group 2 in the mean pain score on VAS (2.53±1.34 vs 1.63±1.09, P=0.002, Mann-Whitney U test), mean postprocedural State Anxiety Inventory pain score (39.4±6.5 vs 34.5±5.8), and postprocedural pulse rate (79.8±5.5 vs 76.0±7.3) (P<0.001 for both, t test). Patients who listened to their preferred music experienced less discomfort and lower anxiety at cystoscopy. Patient age, duration of the procedure, preprocedural STAI-S, and preprocedural pulse rate of each group were comparable. Conclusion: Listening to preferred music during flexible cystoscopy is an easy way to improves male patients' comfort and reduce their anxiety. It could be recommended for male patients.

    Background Testosterone deficiency in patients with heart failure (HF) is associated with decreased exercise capacity and mortality; however, its impact on hospital readmission rate is uncertain. Furthermore, the relationship between testosterone deficiency and sympathetic activation is unknown. Objective We investigated the role of testosterone level on hospital readmission and mortality rates as well as sympathetic nerve activity in patients with HF. Methods Total testosterone (TT) and free testosterone (FT) were measured in 110 hospitalized male patients with a left ventricular ejection fraction < 45% and New York Heart Association classification IV. The patients were placed into low testosterone (LT; n = 66) and normal testosterone (NT; n = 44) groups. Hypogonadism was defined as TT < 300 ng/dL and FT < 131 pmol/L. Muscle sympathetic nerve activity (MSNA) was recorded by microneurography in a subpopulation of 27 patients. Results Length of hospital stay was longer in the LT group compared to in the NT group (37 ± 4 vs. 25 ± 4 days; p = 0.008). Similarly, the cumulative hazard of readmission within 1 year was greater in the LT group compared to in the NT group (44% vs. 22%, p = 0.001). In the single-predictor analysis, TT (hazard ratio [HR], 2.77; 95% confidence interval [CI], 1.58–4.85; p = 0.02) predicted hospital readmission within 90 days. In addition, TT (HR, 4.65; 95% CI, 2.67–8.10; p = 0.009) and readmission within 90 days (HR, 3.27; 95% CI, 1.23–8.69; p = 0.02) predicted increased mortality. Neurohumoral activation, as estimated by MSNA, was significantly higher in the LT group compared to in the NT group (65 ± 3 vs. 51 ± 4 bursts/100 heart beats; p < 0.001). Conclusion These results support the concept that LT is an independent risk factor for hospital readmission within 90 days and increased mortality in patients with HF. Furthermore, increased MSNA was observed in patients with LT. PMID:26200897

    Background Schizophrenia is highly comorbid with cannabis use disorders (CUDs), and this comorbidity is associated with an unfavourable course. Early onset or frequent cannabis use may influence brain structure. A key question is whether comorbid CUDs modulate brain morphology alterations associated with schizophrenia. Methods We used surface-based analysis to measure the brain volume, cortical thickness and cortical surface area of a priori–defined brain regions (hippocampus, amygdala, thalamus, caudate, putamen, orbitofrontal cortex, anterior cingulate cortex, insula, parahippocampus and fusiform gyrus) in male patients with schizophrenia or related disorders with and without comorbid CUDs and matched healthy controls. Associations between age at onset and frequency of cannabis use with regional grey matter volume were explored. Results We included 113 patients with (CUD, n = 80) and without (NCUD, n = 33) CUDs and 84 controls in our study. As expected, patients with schizophrenia (with or without a CUD) had smaller volumes of most brain regions (amygdala, putamen, insula, parahippocampus and fusiform gyrus) than healthy controls, and differences in cortical volume were mainly driven by cortical thinning. Compared with the NCUD group, the CUD group had a larger volume of the putamen, possibly driven by polysubstance use. No associations between age at onset and frequency of use with regional grey matter volumes were found. Limitations We were unable to correct for possible confounding effects of smoking or antipsychotic medication. Conclusion Patients with psychotic disorders and comorbid CUDs have larger putamen volumes than those without CUDs. Future studies should elaborate whether a large putamen represents a risk factor for the development of CUDs or whether (poly)substance use causes changes in putamen volume. PMID:25510948

    The aim of this study was to examine whether an association exists between glutathione S-transferase Mu-1 (GSTM1) gene polymorphism and idiopathic male infertility. Sixty men with primary idiopathic infertility and 60 fertile men, serving as controls, were recruited for the study. The polymorphism was analysed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. The frequency of GSTM1 null genotype was observed to be higher in infertile men 40% in comparison with 33.3% in the fertile men, but this difference was not statistically significant. There was statistically significant difference between cases and controls as regards GSTM1 genotype distribution ((MC) P = 0.006*) in GSTM1-positive men. Patients with the GSTM1 null genotype had significantly lower sperm concentrations and total sperm count when compared with patients with GSTM1-positive genotype. In the control group, men with GSTM1 null genotype had significantly lower sperm concentrations but not total sperm count when compared with men with GSTM1-positive genotype. The results of this study suggest a possible negative effect of GSTM1 null genotype on the spermatogenic potential of the testis. PMID:25130880

    The breast is a rare primary site of hydatid disease and accounts for only 0.27% of cases. Mammary hydatidosis generally occurs in females and has never been described in male patients. In this paper, the authors report a new case of isolated hydatid cyst of the breast in a 35-year-old previously healthy man, who presented with a left breast painless lump of one year duration. Physical examination showed a non-tender and immobile mass in the upper lateral quadrant of the left breast, with normal overlying skin and nipple. There was no palpable lymph node in the left axilla and the contralateral breast was normal. Ultrasonography showed a 2.7 x 1.5 cm cystic lesion in the left breast. The patient underwent total excision of the mass, and histopathological examination confirmed the diagnosis of hydatid cyst. The authors conclude that although hydatid cyst of the breast is rare, it should be considered in the differential diagnosis of breast lumps especially in endemic areas. PMID:24049840

    Objective: To determine physical activity levels during phase IV cardiac rehabilitation in 31 male myocardial infarction patients (median age 62, range 53–77 years). Methods: Patients recorded daily physical activity over 16 weeks in a diary. Diaries were analysed for total general physical activity (TGPA), leisure time physical activity (LTPA), and "active for life" exercise classes (AFL). Pre- and post-observation period (OP) subjects underwent a 10 m shuttle walking test (SWT) to determine changes in aerobic fitness. Rate of perceived exertion (RPE) determined exercise intensity. Estimated gross energy expenditure (EEE) was determined by a regression equation between RPE and Vo2 (l min–1) during SWT. A total of 97% of subjects were on lipid lowering medication. Results: There were no correlations between Vo2 (l min–1) and body mass, therefore kcal min–1 indicated activity intensity. There were no significant changes in physical activity patterns or in aerobic fitness. Estimated total LTPA (median 1376, range 128–3380 kcal week–1) was less than that recommended to improve aerobic fitness and/or slow progression of coronary artery disease. Sixteen subjects attended a median of 29 (range 1–46) AFL during LTPA; one way ANOVA showed these subjects worked at greater EEE (AFL, n = 16, 6.6 (standard deviation 1.4) v no-AFL, n = 15, 5.1 (1.8) EEE kcal min–1, p = 0.017). Conclusion: Physical activity was stable, but patients' EEE appeared insufficient to improve aerobic fitness or slow progression of coronary artery disease. It was suggested that the promotion of LTPA and the availability of AFL classes should be reconsidered. PMID:15728680

    The present study aimed to assess the influence of long-term recombinant human erythropoietin therapy on selected parameters of sexual function in haemodialyzed males with chronic renal failure and severe nephrogenic anaemia. All patients were randomized into two groups. The first one consisted of 11 patients treated for 12 months with rHuEPO in order to achieve and maintain a target Hct value of 30-35% (EPO group). The other 9 male patients were only carefully monitored clinically and biochemically for 12 months similarly as patients of the EPO group but were not treated with rHuEPO (No-EPO group). After 12 months of monitoringan an anonimous questionnaire was completed by the patients describing selected parameters of quality of life and sexual function. Haemodialyzed males treated with rHuEPO showed a significantly higher score of improvement of well-being, exercise tolerance, erection quality and libido as compared with patients not treated with rHuEPO. Results obtained in this study suggest, that EPO therapy shows a beneficial effect on sexual function in haemodialyzed patients with chronic renal failure. PMID:8834648

    Background/Aims To explore and compare quality of life (QoL) differences in female and male patients with fecal incontinence. Methods Ninety-one patients with fecal incontinence (60 women, mean (SD) age 64.13 (9.72) years; 31 men, mean (SD) age 63.61 (13.33) years) were assessed for pathophysiology (anorectal manometry and ultrasound), clinical severity (Wexner and Vaizey scales), QoL (Fecal Incontinence Quality of Life Score [FIQL]) and health status (EQ-5D). Results External and internal anal sphincter impairment rates were 96.5% and 70.2%, respectively, in women, compared to 30% and 43.3% respectively in men (P < 0.05). Clinical severity was similar in both sexes, with mean (SD) Wexner scores of 10.95 (4.35) for women and 9.81 (4.30) for men, and mean (SD) Vaizey scores of 13.27 (4.66) for women and 11.90 (5.22) for men. Scores for women were significantly lower for all FIQL depression and coping subscales (P < 0.001) and the EQ-5D depression subscale (P < 0.01). EQ-5D index was 0.687 (0.20) for women and 0.835 (0.15) for men (P < 0.001). QoL was negatively affected by female gender (?1.336), anxiety/depression (?1.324) and clinical severity (?0.302), whereas age had a positive impact (0.055 per year) (P < 0.01). Conclusions The pathophysiology of fecal incontinence differed between the sexes. For similar severity scores, impact on QoL was higher in women. Gender had the highest impact on QoL compared to other factors. QoL measurements should be part of assessment and treatment protocols. PMID:26486375

    Purpose. The purpose of our study is to determine whether neuroretinal function, measured by the multifocal electroretinogram, differs between males and females with type 2 diabetes and no retinopathy. Methods. This study included 70 eyes from 70 adult subjects (14 control males, 22 control females, 16 males with type 2 diabetes, and 18 females with type 2 diabetes). A template-scaling technique was used to obtain first-order P1 implicit times and N1-P1 amplitudes from photopic multifocal electroretinograms within the central 45 degrees. Results. The males with type 2 diabetes were significantly more abnormal than their female counterparts in two separate analyses of local neuroretinal function. First, the total number of retinal locations with an abnormally delayed implicit time (z score ? 2) was higher (P < 0.001) in the diabetic males (482 locations = 29.2%) compared to the diabetic females (298 locations = 16.1%). Second, in the response topographies that consisted of 103 means of local implicit times for each group, the diabetic males were significantly delayed (P < 0.025) at 23 corresponding positions (22.3%) compared to the diabetic females. At the same time, no corresponding stimulus locations were significantly delayed in the diabetic females compared to the diabetic males. Conclusions. Neuroretinal function is more abnormal in males than in females for adults with type 2 diabetes and no retinopathy. These results suggest that, relative to males, females may have some protection from, or resistance to, neurodegenerative changes that precede the development of background retinopathy in type 2 diabetes.

    We herein present a case report and literature review of dermatofibrosarcoma protuberans in the breast of a male patient. A 27-year-old man presented with a painless lump in his right breast with areas of bluish skin discoloration. The diagnostic work-up comprised clinical examination, ultrasonography, core biopsy, mammography, and magnetic resonance imaging. After surgical excision, the preoperative diagnosis of dermatofibrosarcoma protuberans was proven by pathological examination and immunohistochemistry. The patient was still free of recurrence 1 year after surgical excision. This extremely rare case is, to the best of our knowledge, the fifth such case reported in the literature. PMID:25896773

    Guidelines for cervical cancer screening have evolved rapidly over the last several years, with a trend toward longer intervals between screenings and an increasing number of screening options, such as Pap/HPV co-testing and HPV testing as a primary screening. However, gynecological recommendations often do not include clinical considerations specific to patients on the female-to-male (FTM) spectrum. Both patients and providers may not accurately assess risk for HPV and other sexually transmitted infections, understand barriers to care, or be aware of recommendations for cervical cancer screening and other appropriate sexual and reproductive health services for this patient population. We review the evidence and provide guidance on minimizing emotional discomfort before, during, and after a pelvic exam, minimizing physical discomfort during the exam, and making adaptations to account for testosterone-induced anatomical changes common among FTM patients.

    Personal cooling systems are used to alleviate symptoms of multiple sclerosis and to prevent increased core temperature during daily activities. The objective of this study was to determine the thermal and physiologic responses of patients with multiple sclerosis to short-term maximal head and neck cooling. A Life Support Systems, Inc. Mark VII portable cooling system and a liquid cooling helmet were used to cool the head and neck regions of 24 female and 26 male patients with multiple sclerosis in this study. The subjects, seated in an upright position at normal room temperature (approximately 22 degrees C), were cooled for 30 min by the liquid cooling garment, which was operated at its maximum cooling capacity. Oral, right, and left ear temperatures and cooling system parameters were logged manually every 5 min. Forearm, calf, chest, and rectal temperatures, heart rate, and respiration rate were recorded continuously on a U.F.I., Inc. Biolog ambulatory monitor. This protocol was performed during the winter and summer to investigate the seasonal differences in the way patients with multiple sclerosis respond to head and neck cooling. No significant differences were found between the male and female subject group's mean rectal or oral temperature responses during any phase of the experiment. The mean oral temperature decreased significantly (P < 0.05) for both groups approximately 0.3 degrees C after 30 min of cooling and continued to decrease further (approximately 0.1-0.2 degrees C) for a period of approximately 15 min after removal of the cooling helmet. The mean rectal temperatures decreased significantly (P < 0.05) in both male and female subjects in the winter studies (approximately 0.2-0.3 degrees C) and for the male subjects during the summer test (approximately 0.2 degrees C). However, the rectal temperature of the female subjects did not change significantly during any phase of the summer test. These data indicate that head and neck cooling may, in general, be used to reduce the oral and body temperatures of both male and female patients with multiple sclerosis by the approximate amount needed for symptomatic relief as shown by other researchers. However, thermal response of patients with multiple sclerosis may be affected by gender and seasonal factors, which should be considered in the use of liquid cooling therapy.

    In the present study the occurrence of two heavy metals, arsenic and cadmium, have been reported in the drinking water and seminal plasma of infertile male patients as compared to a control group. The study originated from a survey of geogenic groundwater contamination with the heavy metals arsenic and cadmium in Southern Assam, India as an increase in the incidence of male infertility was being reported from these areas. According to WHO protocol, patients with sperm concentration < 20 x 10(6)/ml were selected as cases (oligozoospermic and azoospermic), and those with > 20 x 10(6)/ml, without any extreme pathological disorders and having fathered a child within 1-2 years of marriage were the control (normozoospermic) group. The study reports an inverse relationship between total sperm count and heavy metal content in drinking water as well as seminal plasma of the subjects. Moreover, a high correlation between altered semenological parameters and lower expression of accessory sex gland markers like fructose, acid phosphatase, and neutral ?-glucosidase in the seminal plasma of patients is reported. The study also highlights significant differences of the sperm function parameters like hypo-osmotic swelling, acrosome reaction, and nuclear chromatin decondensation in the patient group as compared to controls. These findings are significant as they address a likely association between heavy metal stress and altered sperm function as well as seminal enzyme inhibition. PMID:23651453

    This study investigates the prevalence and demographic characteristics of hypersexuality in Parkinson’s disease (PD). Impulse control disorders in PD patients have been associated with dopamine agonist therapy. Moreover, hypersexuality and pathological gambling have been associated with males, while females may be inherently thought to be more likely to participate in compulsive shopping and binge-eating behaviors. In this study, a screening mail-in survey was sent to all PD patients at a single Movement Disorders Center. One hundred forty one of 400 (35.3%) research packets were returned completed. Fifteen of 141 patients met initial screening criteria for hypersexual behavior. After detailed interview, only 6/141 (4.3%) of PD patients met criteria for pathologic hypersexual behavior. These behaviors included: compulsive masturbation, prostitution, and paraphilias. Patients with a younger age of PD onset were more likely to exhibit hypersexual behavior. Unlike previous report, no significant association was found between hypersexuality and gender or dopamine agonist use. Rather, this study suggests that physicians should be vigilant for hypersexual behavior in all PD patients, regardless of gender and PD medication regimen. Ultimately, given the innate sensitivity of the topic and survey limitations, it is very likely that hypersexual behavior in our cohort, as it is in the general PD population, has been under-reported.

    Prospective memory (PM) refers to the ability to remember to perform intended actions in the future. Although PM deficits are a prominent impairment in schizophrenia, little is still known about the nature of PM in symptomatically remitted patients with schizophrenia. To address this issue, event-related brain potentials (ERPs) were recorded from 20 symptomatically remitted patients with schizophrenia and 20 healthy controls during an event-based PM paradigm. Behavioral results showed that symptomatically remitted patients with schizophrenia performed poorly on the PM task compared with healthy controls. On the neural level, the N300, a component of the ERPs related to PM cue detection, was reliable across these two groups, suggesting a degree of functional recovery of processes supporting cue detection in patients with symptomatically remitted schizophrenia. By contrast, the amplitude of the prospective positivity, a component of the ERPs related to PM intention retrieval, was significantly attenuated in symptomatically remitted schizophrenia patients relative to healthy controls. Furthermore, a significant positive correlation between the amplitude of the prospective positivity and accuracy on the PM task was found in those patients, indicating that patients’ poor performance on this task may result from the failure to recover PM cue-induced intention from memory. These results provide evidence for the existence of altered PM processing in patients with symptomatically remitted schizophrenia, which is characterized by a selective deficit in retrospective component (intention retrieval) of PM. Therefore, these findings shed new light on the neurophysiological processes underlying PM in schizophrenia patients during clinical remission. PMID:26483650

    The interaction of advanced glycation end products (AGE) and their specific cell-surface receptor (RAGE) has an important role in the pathogenesis of cardiovascular disease and diabetic complications. Two isoforms of C-truncated RAGE, soluble RAGE (sRAGE) and endogenous secretory RAGE (esRAGE), may prevent activation of RAGE signaling by acting as decoys. This study investigated whether serum esRAGE and sRAGE levels are associated with blood pressure in nondiabetic patients with obstructive sleep apnea (OSA). Male nondiabetic patients (n=139) with OSA were enrolled. Serum esRAGE and sRAGE levels were examined using enzyme-linked immunosorbent assay. Three consecutive seated systolic blood pressure (SBP) and diastolic blood pressure (DBP) measurements were obtained at 5-min intervals in the morning. In univariate analysis, there was a significant correlation between serum esRAGE and SBP or DBP, but not between serum sRAGE and SBP or DBP. Multiple regression analysis showed that SBP was independently associated with waist circumference, HbA1c, minimum SaO2 and serum esRAGE, and that DBP was independently associated with low-density lipoprotein cholesterol, apnea-hypopnea index, serum AGE and body mass index, but not with serum esRAGE. These results indicated that serum esRAGE levels were inversely associated with blood pressure, especially SBP, in male nondiabetic patients with OSA. esRAGE may have a protective role against hypertension in patients with OSA, and it may be a novel biomarker for OSA patients at high risk of developing cardiovascular diseases.

    Background: Type 2 diabetes mellitus (DM) rates are increasing rapidly in South Asians. Cardiovascular complications are more frequent and occur earlier in our patients than patients in many other ethnic groups. Reasons for this are not fully understood. Aims: The aim of this study is to evaluate the body total and central fat percentage in type 2 Diabetes Mellitus patients and to check correlation with BMI, waist circumference and metabolic profile. Settings and Design: A cross-sectional study conducted at endocrine clinic, Aga Khan University Hospital Karachi, Pakistan, from May to December 2012. Materials and Methods: Patients of either gender with type 2 diabetes mellitus were randomly selected. A separate proforma for each patient was recorded for demographics, risk factors, bioelectrical impedance measurement for body fat and investigations. Statistical Analysis: Correlation between body fat and other covariate were compared by Pearson correlation coefficient test. A P < 0.05 was considered significant. SPSS19.0 was used to analyze the data. Results: One hundred and seventy five patients (95 male and 80 female) with mean age of 54.1 ± 12 years were evaluated. Mean duration of diabetes was 8.1 years, mean HbA1c was 8.1% and 53.7% were on oral agents and rest were on insulin with or without oral agents. Hypertension was present in 65.7%, 13.7% had known coronary artery disease and 2.3% had cerebrovascular disease. Mean BMI in males was 29.1 ± 4.74 kg/m2 and females 31.7 ± 5.3 kg/m2. Mean waist circumference in males was 107.3 ± 16.6 cm and 103 ± 12 cm in females. Total body fat percentage (%BF) in males was 30.9 ± 7.1% and females 40 ± 8.2% with 89% of the total cohort having total body fat percentage above the normal, less than 25% central fat percentage was 13.3 ± 5.2% in males and 14.6 ± 5.5% in females with 79.4% of cohort having increased central fat (normal <9%). Total and central body fat correlated with BMI (r = 0.68, P < 0.001) and waist circumference (r = 0.66, P < 0.001) but not with HbA1c, triglyceride level or with fasting or random blood glucose levels. Women had significantly higher total body fat percentage compared to men (P < 0.001) although central fat percentage was similar in both sexes. Conclusions: High body fat percentage, waist circumference are seen especially in woman and central body fat percentage in both sexes among patients with type 2 diabetes mellitus in Pakistan. Body fat percentage should be measured and followed as this may be an important contributing factor to the high macrovascular complication rate in this part of world. PMID:25593830

    Objectives: The purpose of this study was to determine if dynamic postural stability gained one year after ACL reconstruction in patients who received rehabilitation. Methods: Seven male patients (mean age=32,66 ±6,47) who had previously undergone ACL reconstruction (ACL-R) and 7 sex-and general physical activity matched uninjured controls included to study. Mean time since original injury was 13±3,31 months. Dynamic postural control was assessed with 20° knee flexion with Star Excursion Balance test. Each participant performed 3 trials of the anterior, posterior-medial, and posterior-lateral directional components of the SEBT. Reach distances for each directional component were compared with non-injured leg and healthy controls’. Results: There was no significant difference in all directions of Star Excursion Balance test between neither the operated and uninjured knees of patients nor between patients and healthy controls (p>0,05). Conclusion: No deficits in dynamic postural stability were present average one year after ACL reconstruction in patients who received rehabilitation. It can be said that rehabilitation is effective in the recovery of dynamic postural stability.

    All Afro-Caribbean patients admitted to the Mental Illness Division of Rampton Hospital (a Special Hospital) between 1977 and 1986 and a randomly selected control cohort of Non Afro-Caribbean patients admitted in the same period, were compared on a variety of sociodemographic, psychiatric, criminological, treatment and outcome variables. Significantly, fewer of the Afro-Caribbean patients attracted the legal classification of Psychopathic Disorder. Detailed analysis was thus restricted to mentally ill patients in the two ethnic groupings. Similarities outweighed differences. There was no difference between the groups in terms of index offence, previous custodial sentence, in-patient psychiatric admission (including previous Special Hospital admission), admission source, Mental Health Act section, length of admission (including readmission) to Special Hospitals, likelihood of discharge or place to which discharged. Medication history in Special Hospitals was similar at one year and three years after admission. Afro-Caribbean patients had a lower incidence of childhood institutional care, a decreased likelihood of a previous supervision order, an increased likelihood of a previous Court appearance and received higher doses of antipsychotic medication four weeks after admission to Special Hospital.

    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.

    Purpose: The specific aim of this study was to evaluate outcome differences by gender and partner status for patients treated on Radiation Therapy Oncology Group (RTOG) protocol 97-14. Methods and Materials: RTOG 97-14 randomized patients with metastatic breast or prostate cancer to bone to receive 8 Gy in 1 fraction or 30 Gy in 10 fractions. Retreatment rates and overall survival were made based upon gender, marital status, and Karnofsky Performance Status (KPS). The cumulative incidence method was used to estimate retreatment time at 36 months from enrollment, and Gray's test was used to test for treatment differences within the same groupings. Marital status, gender, KPS, and treatment were variables tested in a univariate Cox model evaluating the time to retreatment. Results: Married men and women and single women receiving 30 Gy had significantly longer time to retreatment, p = 0.0067, p = 0.0052, and p = 0.0009 respectively. We failed to show a difference in retreatment rates over time in single men receiving either 30 Gy or 8 Gy. Univariate analysis of the entire group determined patients receiving 30 Gy in 10 fractions significantly less likely to receive retreatment, p < 0.0001, with a trend toward single patients less likely to be re-treated, p = 0.07. Conclusion: Non-disease-related variables, such as social support, might influence the results of clinical trials with subjective endpoints such as retreatment rates. The statistically nonsignificant difference in the 36-month retreatment rates observed in single male patients receiving 8 Gy may be a result of inadequate social support systems in place to facilitate additional care. Patients receiving 8 Gy in a single fraction had significantly higher retreatment rates compared with patients receiving 30 Gy in 10 fractions.

    We evaluated adequate setup margins for the radiotherapy (RT) of pelvic tumors based on overall position errors of bony landmarks. We also estimated the difference in setup accuracy between the male and female patients. Finally, we compared the patient rotation for 2 immobilization devices. The study cohort included consecutive 64 male and 64 female patients. Altogether, 1794 orthogonal setup images were analyzed. Observer-related deviation in image matching and the effect of patient rotation were explicitly determined. Overall systematic and random errors were calculated in 3 orthogonal directions. Anisotropic setup margins were evaluated based on residual errors after weekly image guidance. The van Herk formula was used to calculate the margins. Overall, 100 patients were immobilized with a house-made device. The patient rotation was compared against 28 patients immobilized with CIVCO's Kneefix and Feetfix. We found that the usually applied isotropic setup margin of 8 mm covered all the uncertainties related to patient setup for most RT treatments of the pelvis. However, margins of even 10.3 mm were needed for the female patients with very large pelvic target volumes centered either in the symphysis or in the sacrum containing both of these structures. This was because the effect of rotation (p ? 0.02) and the observer variation in image matching (p ? 0.04) were significantly larger for the female patients than for the male patients. Even with daily image guidance, the required margins remained larger for the women. Patient rotations were largest about the lateral axes. The difference between the required margins was only 1 mm for the 2 immobilization devices. The largest component of overall systematic position error came from patient rotation. This emphasizes the need for rotation correction. Overall, larger position errors and setup margins were observed for the female patients with pelvic cancer than for the male patients.

    X-Linked adrenoleukodystrophy (ALD) is a genetic disease associated with demyelination of the central nervous system, adrenal insufficiency, and accumulation of very long chain fatty acids in tissue and body fluids. ALD is due to mutation of a gene located in Xq28 that encodes a peroxisomal transporter protein of unknown function. The most common phenotype of ALD is the cerebral form (45%) that develops in boys between 5-12 yr. Adrenomyeloneuropathy (AMN) involves the spinal cord and peripheral nerves in young adults (35%). Adrenal insufficiency (Addison`s disease) is frequently associated with AMN or cerebral ALD and may remain the only clinical expression of ALD (8% of cases). The prevalence of ALD among adults with Addison`s disease remains unknown. To evaluate this prevalence, we performed biochemical analysis of very long chain fatty acids in 14 male patients (age ranging from 12-45 yr at diagnosis) previously diagnosed as having primary idiopathic adrenocortical insufficiency. In 5 of 14 patients (35%), elevated plasma concentrations of very long chain fatty acids were detected. None of these patients had adrenocortical antibodies. By electrophysiological tests and magnetic resonance imaging it was determined that two patients had cerebral ALD, one had adrenomyeloneuropathy with cerebral involvement, and two had preclinical AMN. Our data support the hypothesis that ALD is a frequent cause of idiopathic Addison`s disease in children and adults. 30 refs., 5 tabs.

    The aim of the study was to determine whether different sleep stages, especially REM sleep, affect QT interval duration and variability in male patients without obstructive sleep apnea (OSA). Polysomnographic recordings of 30 patients were analyzed. Beat-to-beat QT interval variability was calculated using QTV index (QTVI) formula. For QTc interval calculation, in addition to Bazett's formula, linear and parabolic heart rate correction formulas with two separate ? values were used. QTVI and QTc values were calculated as means of 2 awake, 3 NREM, and 3 REM sleep episodes; the duration of each episode was 300?sec. Mean QTVI values were not statistically different between sleep stages. Therefore, elevated QTVI values found in patients with OSA cannot be interpreted as physiological sympathetic impact during REM sleep and should be considered as a risk factor for potentially life-threatening ventricular arrhythmias. The absence of difference of the mean QTc interval values between NREM and REM stages seems to confirm our conclusion that sympathetic surges during REM stage do not induce repolarization variability. In patients without notable structural and electrical remodeling of myocardium, physiological elevation in sympathetic activity during REM sleep remains subthreshold concerning clinically significant increase of myocardial electrical instability.

    Background Studies on the relationship between coronary artery calcium and aortic diameter are scarce. The aim of the current study was to evaluate the correlation between coronary artery calcium score (CACS) and maximal thoracic and abdominal aortic diameters in a population of elderly (>65 years) male hypertensive patients at high risk for coronary artery disease. Patients and methods From June 2012 to April 2013, we prospectively enrolled 393 male hypertensive patients older than 65 years of age who had no history of aortic aneurysm. Coronary artery calcium and maximal diameters of the ascending thoracic aorta (ATAmax), descending thoracic aorta (DTAmax), and abdominal aorta (AAmax) were measured using noncontrast computed tomography imaging. Aortic diameters are indexed to body surface area (BSA). Participants were divided into five groups according to CACS (0, 1–10, 10–100, 100–400, and > 400). Results The mean ATAmax/BSA, DTAmax/BSA, and AAmax/BSA were 22.0 ± 2.7, 16.3± 1.9, and 13.0± 2.9 mm, respectively. On multivariate analysis, ATAmax/BSA was associated independently with age, diabetes, and history of aortic valve replacement (all P < 0.001). DTAmax/BSA was associated independently with age (P < 0.001). However, there were no significant correlations between thoracic aorta diameter and CACS. In contrast, AAmax/BSA was associated independently with CACS as well as age and history of smoking (P = 0.014, 0.003, and 0.019, respectively). Abdominal aortic aneurysm (>30 mm) was more prevalent in patients with a CACS of 400 or more compared with the others (14 vs. 3%, P < 0.001). Conclusion CACS was associated with increased abdominal aorta diameter, but not with thoracic aorta diameter. Therefore, screening for an abdominal aortic aneurysm is warranted in patients with a high risk of coronary artery disease and a high CACS. However, the necessity for thoracic aortic aneurysm screening is not clear in these patients. PMID:25051100

    Evidence in rodents suggests that tacrolimus-induced posttransplant hypertension is due to upregulation of the thiazide-sensitive Na(+)-Cl(-) cotransporter NCC. Here, we analyzed whether a similar mechanism is involved in posttransplant hypertension in humans. From January 2013 to June 2014, all adult kidney transplant recipients receiving a kidney allograft were enrolled in a prospective cohort study. All patients received tacrolimus as part of the immunosuppressive therapy. Six months after surgery, we assessed general clinical and laboratory variables, tacrolimus trough blood levels, and ambulatory 24-h blood pressure monitoring. Urinary exosomes were extracted to perform Western blot analysis using total and phospho-NCC antibodies. A total of 52 patients, including 17 women and 35 men, were followed. At 6 mo after transplantation, of the 35 men, 17 developed hypertension and 18 remained normotensive, while high blood pressure was observed in only 3 of 17 women. The hypertensive patients were significantly older than the normotensive group; however, there were no significant differences in body weight, history of acute rejection, renal function, and tacrolimus trough levels. In urinary exosomes, hypertensive patients showed higher NCC expression (1.7 ± 0.19) than normotensive (1 ± 0.13) (P = 0.0096). Also, NCC phosphorylation levels were significantly higher in the hypertensive patients (1.57 ± 0.16 vs. 1 ± 0.07; P = 0.0049). Our data show that there is a positive correlation between NCC expression/phosphorylation in urinary exosomes and the development of hypertension in posttransplant male patients treated with tacrolimus. Our results are consistent with the hypothesis that NCC activation plays a major role in tacrolimus-induced hypertension. PMID:26336164

    Hypersexuality remains an increasingly common but poorly understood patient complaint. Despite diversity in clinical presentations of patients referred for hypersexuality, the literature has maintained treatment approaches that are assumed to apply to the entire phenomenon. This approach has proven ineffective, despite its application over several decades. The present study used quantitative methods to examine demographic, mental health, and sexological correlates of common clinical subtypes of hypersexuality referrals. Findings support the existence of subtypes, each with distinct clusters of features. Paraphilic hypersexuals reported greater numbers of sexual partners, more substance abuse, initiation to sexual activity at an earlier age, and novelty as a driving force behind their sexual behavior. Avoidant masturbators reported greater levels of anxiety, delayed ejaculation, and use of sex as an avoidance strategy. Chronic adulterers reported premature ejaculation and later onset of puberty. Designated patients were less likely to report substance abuse, employment, or finance problems. Although quantitative, this article nonetheless presents a descriptive study in which the underlying typology emerged from features most salient in routine sexological assessment. Future studies might apply purely empirical statistical techniques, such as cluster analyses, to ascertain to what extent similar typologies emerge when examined prospectively. PMID:25032736

    Medullary thyroid carcinoma (MTC) is a rare malignancy that may metastasize to liver, lungs and bones. Breast is an unusual metastatic site for MTC and only 20 female cases have been reported in the literature. We present a male patient in whom histological examination and immunohistochemistry of a breast mass were indicative of breast metastasis from MTC. A 67-year-old man with recent diagnosis of MTC and metastases to cervical and upper mediastinum lymph nodes was referred to our department for further treatment. At first evaluation, diagnostic imaging techniques showed lung and bone metastases and three months later the presence of liver metastases. Due to the extension of the disease, treatment with vandetanib was decided, but serious adverse events led to its interruption after two weeks. During follow-up, patient developed a painful swelling in the right breast. Ultrasound and mammography showed the presence of multiple masses to the right breast suspicious for malignancy. Core needle biopsy and histological examination of the specimen confirmed the presence of metastatic MTC. Palliative external beam irradiation was used to relieve local pain and, after one month, the patient died. Consequently, breast masses should be cautiously evaluated, mainly in the presence of a known primary malignancy. Histological and/or cytopathological examination are requisite diagnostic tools, while external beam irradiation and tyrosine kinase inhibitors may be used as palliative therapies in the concurrent presence of breast metastases from MTC.

    Ramadan fasting is believed to be beneficial. We assessed a random sample of 100 Egyptian male schizophrenia outpatients using the Positive and Negative Syndrome Scale (PANSS) and dietary, anthropometric, clinical, and laboratory measures at baseline (T1) before Ramadan of 2014 and during the fourth week of Ramadan (T2). The metabolic syndrome was identified in 31 patients and these showed a reduction of high-density lipoprotein cholesterol (HDLc) and brain-derived neurotrophic factor (BDNF) concentrations and increase in the levels of dietary intakes, body mass index (BMI), waste circumference, systolic and diastolic blood pressure, all PANSS subscales, glucose, insulin, HOMA-IR, total cholesterol, triglycerides, low-density lipoprotein-cholesterol (LDL-c), white blood cells, granulocytes, lymphocytes, monocytes, fibrinogen and high-sensitivity C-reactive protein (hs-CRP). In a multiple regression analysis, total energy intake and body mass index (BMI) emerged as the main independent predictors of deterioration in most inflammatory and psychopathology parameters. These findings did not support our hypothesis but suggested that Ramadan fasting has a negative impact on schizophrenia patients, especially those with metabolic syndrome. This could draw attention to the need in the psycho-education management of such patients to focus more on nutrition education for safe fasting. PMID:25529262

    Estrogens role in schizophrenia patients is a subject, which has gained an increased attention from the medical community. Estrogens have been shown to inhibit dopamine actions, improve neuronal regeneration, and overall, have a protective role in the pathology of schizophrenia. The adjunctive estrogen therapy for men is currently under debate. Antipsychotic medication is known to influence the hypothalamo-hypophyseal – gonadal axis by inducing variable degrees of hyperprolactinemia. Several studies have found that some of the atypical antipsychotics lower cortisol levels in patients and also in healthy controls. We have investigated the effects of clozapine and risperidone on estradiol levels in men with schizophrenia. We have also evaluated the levels of prolactin and cortisol, taking into account the possible influence of antipsychotic drugs on both these hormones. Both prolactin and cortisol also have the potential to regulate sexual hormones biosynthesis. Our study found decreased estradiol levels in men with schizophrenia treated with clozapine and risperidone, while prolactin levels were increased only in the risperidone treated group. Cortisol levels are not statistically significant different between groups.

    Finasteride at 1 mg/day and 5% topical minoxidil are effective in male androgenetic alopecia (MAGA). However, studies describing their effects in Chinese individuals are scarce. 450 Chinese MAGA patients were randomly assigned to receive finasteride (n = 160), minoxidil (n = 130) and combined medication (n = 160) for 12 months. The patients returned to the clinic every 3 months for efficacy evaluation. And efficacy was evaluated in 428 men at treatment end, including 154, 122, and 152 in the finasteride, 5% minoxidil, and combination groups, respectively. All groups showed similar baseline characteristics, including age at enrollment, and duration and severity of alopecia (p > 0.05). At 12 months, 80.5, 59, and 94.1% men treated with finasteride, 5% minoxidil and the combination therapy showed improvement, respectively. Adverse reactions were rare (finasteride, 1.8%; minoxidil, 6.1%), and disappeared right after drug withdrawal. In conclusion, finasteride is superior to 5% minoxidil, while the combined medication showed the best efficacy. PMID:26031764

    There is accumulating evidence that ceruloplasmin, a copper-containing protein with ferroxidase activity, plays an important role in iron metabolism. Reduction of ferroxidase activity secondary to ceruloplasmin deficiency may induce iron accumulation in various organs as the result of impaired iron transport. A 37-year-old man presented with intention tremor of the right hand. Liver function tests were almost normal, but parameters of trace elements were abnormal: hypocupremia, hypoceruloplaminemia, and hyperferritinemia. Imaging of the abdomen showed a cirrhotic liver with increased density. A diagnosis of the neurological form of Wilson disease was confirmed by copper deposits in the liver obtained by a blind biopsy, and the patient was diagnosed as compound heterozygous for ATP7B mutations. He was treated with 2500 mg/day trientine hydrochloride per os. The second examination was performed after 20 months of treatment. The treatment further reduced serum ceruloplasmin level from 8.9 to less than 4.0 mg/dl. Serum ferroxidase activity was as low as 70 U/l during treatment. Posttreatment liver histology became negative for copper but remained positive for iron. Copper X-rays from hepatocyte lysosomes were no longer detected, but the iron X-ray was still very high post treatment. Thus, microanalysis confirmed compound overload of copper and iron in this male patient with Wilson disease. PMID:11479773

    Purpose: To evaluate follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone levels after postoperative chemoradiation in men with rectal cancer. Methods and Materials: Forty-three men with rectal cancer had baseline and postchemoradiation FSH, LH, and testosterone measured. Adjuvant chemoradiation consisted of two 5-day cycles of bolus 5-fluorouracil (5-FU) every 4 weeks at a dose of 500 mg/m{sup 2}/d followed by concurrent chemoradiation followed by two additional 5-day cycles of 5-FU at a dose of 450 mg/m{sup 2}/d. Continuous-infusion 5-FU at 225 mg/m{sup 2}/d was given during radiation. Pelvic radiation consisted of a three- or four-field technique with a median dose of 54.0 Gy in 30 fractions. Results: Median follow-up was 6.1 years. Mean baseline FSH levels increased from 5.3 to a peak of 23.9 IU/L (p < 0.001) 13-24 months after chemoradiation. Mean baseline LH levels increased from 4.3 to a peak of 8.5 IU/L (p < 0.001) within 6 months after chemoradiation. Mean testosterone levels decreased from 15.4 nmol/L at baseline to 8.0 nmol/L more than 4 years after chemoradiation. Mean testosterone to mean LH ratio decreased from 4.4 at baseline to 1.1 after 48 months posttreatment, suggesting a continued decrease in Leydig cell function with time. Testicular dose was measured in 5 patients. Median dose was 4 Gy (range, 1.5-8.9 Gy). Conclusions: Chemoradiation in men with rectal cancer causes persistent increases in FSH and LH levels and decreases in testosterone levels.

    Background Heavy metal pollutants such as cadmium (Cd), lead (Pb), and mercury (Hg) are rarely the subjects of cardiovascular research although they have been suspected for decades to negatively impact the circulatory system. Methods Apart from detailed anamnestic data, urinary levels of Cd and full blood levels of Pb and Hg were measured in 53 female (mean age: 68.04±7.03 years) and 111 male (mean age: 60.68±11.43 years) nonsmoking or never-smoking patients with angiographically verified and precisely quantified coronary artery disease (CAD). Results Although Cd was quantifiable in 68.3% of subjects, only 34.1% of these patients exceeded the critical 1 ?g/L Human Biomonitoring (HBM)-I level. Median Pb (20 ?g/L) and Hg (0.55 ?g/L) levels were lower than the HBM-I, as well as reference levels of Pb. Wine consumption was the main source for Pb, fish and wine consumption for Hg, and previous nicotine abuse for Cd. There was no correlation between Cd, Pb, or Hg and severity of CAD although severity correlated positively with atherosclerosis parameters (uric acid, creatinine, triglycerides, blood urea nitrogen, C-reactive protein) and negatively with high density lipoprotein cholesterol. Conclusion Cd levels detected in CAD patients were high compared to German and European reference levels but it could not be proven that urine levels of Cd and blood levels of Hg or Pb played a major role in the genesis of CAD, particularly when compared to well-known biomarkers such as blood pressure, glucose, and lipids.

    Patients who have been discharged from forensic services often have conditions they have to abide by as part of their discharge, and failure to do so leads to recall. We interviewed six men who had been conditionally discharged from forensic services and then been recalled into hospital to find out what they thought went wrong. The reasons they gave for why things went wrong included feeling that the system was unfair and made them feel like criminals even though they did not feel they had put anyone at risk. Some of them were not fully aware of the conditions they needed to adhere to, and some of them had breached the conditions but did not take responsibility for what had happened. In addition, supervision was felt to be very controlling and disruptive rather than supportive when patients were often lonely, bored and needing support. Most participants reported that they experienced poor standards of aftercare in hostels they were required to reside in. In the future, care of patients after conditional discharge should include better communication between patients and their supervisory team, recognition of the need for more support and improvements in the standards of care in hostels, as well as a collaborative approach to risk assessment that might reduce the frequency of relapse and readmission. This study explores how male patients suffering from dual diagnosis in a forensic unit perceive being recalled and readmitted following conditional discharge and their views about how services might be improved. A qualitative approach was used drawing on grounded theory techniques. Audiotaped semistructured interviews collected data from a purposefully selected sample of six participants who had been recalled and met the inclusion criteria of the study. Data were analysed using the constant comparative method. Most participants perceived the recall system as unfair, inappropriately criminalized their behaviour and was based on an assessment of risk that they did not understand or accept. Participants were not fully aware of the conditions of their discharge, and most did not accept responsibility for their role in being recalled and blamed the system. Care following discharge was rarely seen as positive, and poor standards in hostels were reported by most participants. Supervision was often seen as disruptive and controlling, and focused more on surveillance rather than support. Better communication might have helped them understand and adhere to the conditions of their discharge. Participants identified the importance of family and friends to their recovery, the importance of having their own accommodation, and the need to be more independent. PMID:23651216

    This study determined the body burden of PBDEs in 100 California children, and evaluated associations with sociodemographic, household, and dietary factors. In national and international comparisons, California dust, breast milk, and human serum samples contain higher concentrations of PBDEs. Higher levels in children suggest exposure pathways depend upon age. Plasma samples were analyzed for PBDEs using GC/MS. Circulating levels of PBDEs were 10-to 1000-fold higher than similar aged populations in Mexico and Europe, 5-times higher than similar aged children across the U.S., and 2- to 10-fold higher than U.S. adults. Increased levels of higher-brominated congeners were associated with the recent purchase of new upholstered furniture or mattresses and consumption of pork. Concentrations of lower-brominated congeners increased with frequency of poultry consumption. Lower maternal education was independently and significantly associated with higher levels of most congeners in the children. PMID:20196589

    46 year old male with past medical history of schizoaffective disorder and chronic lower back pain, was admitted for management of worsening depression and anxiety. He was started on gabapentin, 300mg twice daily for his back pain and anxiety symptoms. His only other medication was hydrocodone. Over next few days, he started developing worsening bilateral lower extremity edema. He did not have any cardiovascular related symptoms. Physical exam was only significant for 3+ pitting edema with all laboratory values and imaging being unremarkable. Gabapentin was discontinued and his lower extremity swelling improved over subsequent days. Incidence of pedal edema with gabapentin use is approximately 7 to 7.5% with all studies being in elderly patients receiving doses above 1200 mg/day. This case illustrates that lower doses of gabapentin can also cause this adverse effect. It is important to recognize this adverse effect because gabapentin is used in conditions like diabetic neuropathy, which is associated with multiple co-morbidities that can give rise to bilateral leg swelling. Presence of gabapentin induced leg swelling can thus confound the clinical picture.

  5. H-Y antibody titers are increased in unexplained secondary recurrent miscarriage patients and associated with low male : female ratio in subsequent live births

    BACKGROUND The birth of a boy is significantly more common than a girl prior to secondary recurrent miscarriage (SRM) and is associated with a poorer chance of a subsequent live birth. Children born after SRM are more likely to be girls. High-titer antisera specific for male antigens (H-Y) have been shown to arrest development of male bovine embryos efficiently. We consequently questioned the role of H-Y antibodies in women with SRM. METHODS Serum samples from patients with unexplained SRM (n = 84), unexplained primary recurrent miscarriage (PRM) (n = 12) and healthy women (n = 37) were obtained. The samples were taken during pregnancy (gestational weeks 4–5) for 77 (80%) of the patients. Enzyme-linked immunosorbent assay was used to detect immunoglobulin G antibodies that specifically recognized any of the five recombinant H-Y proteins (EIF1AY, RPS4Y1, ZFY, DDX3Y and UTY) and their H-X homologs. RESULTS H-Y-specific antibodies were more frequent in SRM patients (46%) compared with female controls (19%, P = 0.004) and PRM patients (8%, P = 0.01). The presence of H-Y antibodies in early pregnancy was associated with a low male: female birth ratio among the subsequent live births, as only 12% of children born to H-Y antibody-positive patients were boys compared with 44% boys born to H-Y antibody negative patients (P = 0.03). CONCLUSIONS The high frequency of H-Y antibody-positive SRM patients and the association between the presence of these antibodies in early pregnancy and the low number of male offspring, suggest that maternal immune responses against H-Y antigens can cause pregnancy losses. Further exploring these mechanisms may increase our understanding of unexplained SRM. PMID:20823116

    Methylenetetrahydrofolate reductase (MTHFR), the key enzyme of the folate metabolic pathway, has been reported to be five times more active in the testicles compared to other organs in adult mice. The aim of this study was to investigate the relationship between MTHFR c.677C>T and c.1298A>C polymorphisms and infertility in nonobstructive azoospermic and oligozoospermic male patients living in the Trakya region of Turkey. The study population included 75 nonobstructive azoospermic and 62 oligozoospermic, nonconsanguineous patients who were referred to the Department of Medical Genetics of Trakya University between 01.03.2012 and 01.06.2013 due to infertility and who had been diagnosed based on clinical examinations and spermiograms. All of the patients had a normal karyotype without a Y chromosome microdeletion. Melting curve analysis with labelled probes and primers that were designed by the manufacturers and the real-time polymerase chain reaction method were used. The MTHFR c.677TT genotype frequency in the oligozoospermic infertile male patient group was greater than that of the fertile control group [odds ratio (OR) = 2.675 (95% CI: 0.979-7.305), (P < 0.048)]. The MTHFR c.677TT genotype may be a genetic risk factor for oligozoospermic infertile male patients who live in the Trakya region of Turkey. PMID:25428700

    Chromosomes occupy specific distinct areas in the nucleus of the sperm cell that may be altered in males with disrupted spermatogenesis. Here, we present alterations in the positioning of the human chromosomes 15, 18, X and Y between spermatozoa with the small supernumerary marker chromosome (sSMC; sSMC+) and spermatozoa with normal chromosome complement (sSMC?), for the first time described in the same ejaculate of an infertile, phenotypically normal male patient. Using classical and confocal fluorescent microscopy, the nuclear colocalization of chromosomes 15 and sSMC was analyzed. The molecular cytogenetic characteristics of sSMC delineated the karyotype as 47,XY,+der(15)(pter->p11.2::q11.1->q11.2::p11.2->pter)mat. Analysis of meiotic segregation showed a 1:1 ratio of sSMC+ to sSMC? spermatozoa, while evaluation of sperm aneuploidy status indicated an increased level of chromosome 13, 18, 21 and 22 disomy, up to 7?×?(2.7???15.1). Sperm chromatin integrity assessment did not reveal any increase in deprotamination in the patient’s sperm chromatin. Importantly, we found significant repositioning of chromosomes X and Y towards the nuclear periphery, where both chromosomes were localized in close proximity to the sSMC. This suggests the possible influence of sSMC/XY colocalization on meiotic chromosome division, resulting in abnormal chromosome segregation, and leading to male infertility in the patient.

    A 25-year-old gravid woman, homozygous for sickle cell anemia, with a history of recent deep venous thrombosis, was examined using Tc-99m labeled red blood cell venography for recurrent thrombosis. Although negative for thrombus, the study presented an unusual incidental finding: the patient's peripheral bone marrow was hyperemic in a distribution consistent with peripheral red bone marrow expansion. Such a pattern has not been documented before using this technique. This report supports other literature that has demonstrated hyperemia of peripheral red bone marrow in other hemolytic anemias. This finding may ultimately define an additional role of scintigraphy in assessing the pathophysiologic status of the sickle cell patient.

    Objective: The safest and most effective conservative treatment for patients with lumbar disc herniation (LDH) has not been established. The purpose of this study was to evaluate the effect of lumbar spine stabilization exercise (LSSE) and general exercise (GE) on pain intensity and functional capacity in young male patients with LDH. Methods: Sixty-three young male adults aged 20 to 29 years with the diagnosis of LDH were enrolled and divided into an LSSE group (n=30) and a GE group (n=33). Patients in both groups received low-power laser (LPL) therapy during the first week of the onset of LDH. Patients in the GE group underwent a GE program. Patients in the LSSE group followed an LSSE program for 3 months. All of the patients were subjected to pain intensity and functional capacity evaluations four times: at pre-and post-LPL therapy, and at 3 months and 1 year post-exercise. Pain intensity of the lower back and legs was evaluated with the visual analogue scale (VAS), and functional capacity was evaluated with the Oswestry Disability Index (ODI). Results: Both groups showed a significant reduction in VAS and ODI scores at 3 and 12 months post-exercise compared with before treatment (P<0.001). The LSSE group showed a significant reduction in the average score of the VAS for low back pain (P=0.012) and the ODI (P=0.003) at 12 months post-exercise compared with the GE group. Conclusions: LSSE and GE are considered as effective interventions for young male patients with LDH. Moreover, LSSE is more effective than GE, and physical therapy, such as LPL, is required during acute LDH. PMID:26309670

    Kartagener's syndrome (KS) is an autosomal recessive genetic disease accounting for approximately 50% of the cases of primary ciliary dyskinesia (PCD). As it is accompanied by many complications, PCD/KS severely affects the patient's quality of life. Therapeutic approaches for PCD/KS aim to enhance prevention, facilitate rapid definitive diagnosis, avoid misdiagnosis, maintain active treatment, control infection and postpone the development of lesions. In male patients, sperm flagella may show impairment in or complete absence of the ability to swing, which ultimately results in male infertility. Assisted reproductive technology will certainly benefit such patients. For PCD/KS patients with completely immotile sperm, intracytoplasmic sperm injection may be very important and even indispensable. Considering the number of PCD/KS susceptibility genes and mutations that are being identified, more extensive genetic screening is indispensable in patients with these diseases. Moreover, further studies into the potential molecular mechanisms of these diseases are required. In this review, we summarize the available information on various aspects of this disease in order to delineate the therapeutic objectives more clearly, and clarify the efficacy of assisted reproductive technology as a means of treatment for patients with PCD/KS-associated infertility.

    Skin samples taken from 6 female patients receiving allogeneic bone marrow transplants (BMT) from male siblings (n=5) or from unrelated human leukocyte antigen (HLA)-matched male donor (n=1) due to hematological malignancies were studied for the presence of donor cells. One nontransplanted male and 1 female control that received female BM were used as further controls of the technique. Skin biopsies were taken from the scalp and the back from each patient 12-16 years after the successful BMT. We have found donor chimerism in all of the 6 patients in both of their biopsies. Using single and double immunostainings in combination with Y chromosome hybridization, we observed that there are cytokeratin-expressing donor-derived cells in the epidermis of all the 6 patients, the numbers being slightly higher in the scalp (0.37%-1.78%) than in the back (0.32%-1.08%) biopsies. The indication for BMT, and the age of the patient did not seem to have any effect on the numbers found. A few of the double-labeled cells also stained for Ki67, a marker of cellular proliferation, suggesting that the engrafted cells were able to further divide in the epidermis. In 2 patients we observed patches of donor keratinocytes within the epidermis, suggesting a clonal origin. We conclude that in agreement with some and in contrast to other published studies, BM-derived circulating cells are able to engraft in the human skin and to further proliferate there and thus contribute to tissue renewal. These data raise the possibility to use BM cells in regenerative medicine to help in extended injuries, large surface burns, or lack of skin due to other reasons. PMID:21288071

    Increased awareness of the importance of fertility concerns to teenage cancer survivors is leading to growing numbers of male teenagers being offered sperm banking at the time of diagnosis. This is now extending to males diagnosed with other conditions where gonadotoxic agents are used in treatment. The storage of sperm in these circumstances is a challenging aspect of health care, given the complex issues and timescale involved. UK law has been enacted to protect legal minors from the potentially harmful effects of exposure to pornographic materials, yet there is reason to suppose that their use in this context could have therapeutic benefit in aiding successful masturbation. This paper uses material gained through consultation with the eleven largest UK sperm banks and 94 male teenage cancer survivors, to discuss the associated legal and ethical dilemmas, including those around the role of parents/carers. Findings suggest that there is variable practice in sperm banks, that almost a quarter of teenage males wanted access to soft porn when banking sperm, and half wanted to bring in their own materials. It concludes that there is an urgent need for any legal barriers to the therapeutic use of pornographic materials to be understood and examined. PMID:17786648

    The aim of our study was to compare short-term outcomes of robotic and laparoscopic sphincter-saving total mesorectal excision (TME) in male patients with mid-low rectal cancer (RC) after neadjuvant chemoradiotherapy (NCRT). The study was conducted as a retrospective review of a prospectively maintained database, and we analyzed 14 robotic and 65 laparoscopic sphincter saving TME (R-TME and L-TME, respectively) performed by one surgeon between 2005 and 2013. Patient characteristics, perioperative recovery, postoperative complications and and pathology results were compared between the two groups. The patient characteristics did not differ significantly between the two groups. Median operating time was longer in the R-TME than in the L-TME group (182 min versus 140 min). Only two conversions occurred in the L-TME group. No difference was found between groups regarding perioperative recovery and postoperative complication rates. The median number of harvested lymph nodes was higher in the RTME than in the L-TME group (32 versus 23, p = 0.008). The median circumferential margin (CRM) was 10 mm in the R-TME group, 6.5 mm in the L-TME group (p = 0.047. The median distal resection margin (DRM) was 27.5 mm in the R-TME, 15 mm in the L-TME group (p = 0.014). Macroscopic grading of the specimen in the R-TME group was complete in all patients. In the L-TME group, grading was complete in 52 (80 %) and incomplete in 13 (20 %) cases (p = 0.109). R-TME is a safe and feasible procedure that facilitates performing of TME in male patients with mid-low RC after NCRT. PMID:26531198

    The purpose of this study is to compare the racial differences in treatment and overall survival (OS) of male breast cancer (MBC) patients. Data were extracted from the NCI SEER database that included population-based registries from 1988 to 2010 and analyzed using SPSS 20.0. 4,279 MBC patients were identified. 3,266 (76.3%) patients were White, 552 (12.9%) Black, 246 (5.7%) Hispanic, and 215 (5.0%) Asian. Black patients were more likely to be diagnosed at younger age (P < 0.001), have advanced stage disease (P = 0.001), and be unmarried (P < 0.001) and less likely to undergo lymph node dissection (P = 0.006). When stratified by stage, there was no difference in receipt of primary treatment by race. The 5-year OS for White, Black, Hispanic, and Asian races was 73.8%, 66.3%, 74.0%, and 85.3% (P < 0.001). This significant worse 5-year OS for Blacks persisted regardless of age, stage II or III disease, and grade 2 or 3 disease. On multivariate analysis, Black race was a significant independent prognostic factor for worse OS. Blacks were less likely to receive lymph node dissection of which patients may derive benefit, though we did not observe receipt of primary treatment, after stratifying for disease stage, to be an underlying factor contributing to racial outcome differences.

    Objective Quantitative electroencephalography (qEEG) has been increasingly used to evaluate patients with attention deficit hyperactivity disorder (ADHD). The aim of this study was to assess the correlation between qEEG data and symptom severity in patients with ADHD. Methods Fifteen patients with ADHD and 20 healthy controls (HCs) were recruited. Electroencephalography was assessed in the resting-state, and qEEG data were obtained in the eyes-closed state. The Korean version of the ADHD Rating Scale (K-ARS) and continuous performance tests (CPTs) were used to assess all participants. Results Theta-band (4–7 Hz) power across the brain was significantly positively correlated with inattention scores on the K-ARS, reaction times and commission errors on the CPTs in ADHD patients. Gamma-band (31–50 Hz) power was significantly positively correlated with the results of the auditory CPTs in ADHD patients. The theta/alpha (8–12 Hz) and theta/beta (13–30 Hz) ratios were significantly negatively correlated with commission and omission errors on auditory CPTs in ADHD patients. No significant correlations between qEEG relative power and K-ARS and CPT scores were observed in HCs. Conclusion Our results suggest that qEEG may be a useful adjunctive tool in patients with ADHD.

    Isolated male hypogonadotropic hypogonadism (IHH) can be congenital or acquired. Mean platelet volume (MPV), determinant of platelet function, is an independent risk factor for cardiovascular disease (CVD). The aim of this study was to evaluate MPV values in male IHH and the relationships between MPV, low testosterone levels, metabolic syndrome, impaired fasting glucose (IFG) and cardiovascular risk. Thirty-one patients with untreated, normosmic, isolated, male IHH (mean age 22.5?±?7.58 years) and 30 age and BMI-matched healthy individuals (mean 22.51?±?4.94 years) were included in the study. All hormonal analyses were done by chemiluminesance assay. All study participants were evaluated by biochemical and platelet parameters. MPV were significantly higher in IHH than controls (8.6?±?0.65 and 7.6?±?0.54?fl, respectively; P?=?0.000). MPV had a positive correlation between metabolic syndrome (r?=?0.444; P?=?0000), IFG (r?=?0.371; P?=?0.04), insulin (r?=?0.820; P?=?0.02), homeostasis model assessment (HOMA)-IR (r?=?0.822; P?=?0.0023) and BMI (r?=?0.373; P?=?0.012). MPV had a negative correlation between total testosterone (r?=?-0.586; P?=?0.0000), free testosterone (r?=?-0.634; P?=?0.0000), luteinizing hormone (r?=?-0.471; P?=?0.0000) and FSH (r?=?-0.434; P?=?0.0000).

    The telomere length and subtelomeric methylated status of peripheral blood leukocytes has been reported to be correlated with many kinds of pathophysiological conditions. However, the correlation between the telomeric parameters and clinical laboratory data in metabolic disorders is not well known. This study investigated the correlation between the telomere length and subtelomeric methylated status in peripheral leukocytes and the laboratory data of male outpatients with combined metabolic disorders and no clinical history of cardiovascular or cerebrovascular event were assessed, to find good clinical laboratory markers reflecting the biological aging. The laboratory data were collected in 26 Japanese male outpatients with diabetes mellitus and hyperlipidemia, and no history of cardiovascular or cerebrovascular event, and the telomeric parameters in their peripheral leukocytes were determined by Southern blot with methylation-sensitive and insensitive isoschizomers. Any correlations between the laboratory data and the telomeric parameters were assessed. The patients showed a significant negative correlation among the bilirubin and creatine phosphokinase with the aging-associate change of the telomeric and subtelomeric parameters. Lowered serum bilirubin and creatinine phosphokinase level correlated to genomic aging represented by telomere attrition of patients with metabolic disorders. PMID:20670100

    Background. Prostate cancer in men raises many of the same issues that breast cancer does in women. Complications of prostate cancer treatment, including impotence and incontinence, affect the self-image and psyche of a man no less than does the loss of a breast in a woman. We present a pilot study in which 21 patients were treated with a focal cryoablation procedure. Methods. Focal cryoablation was performed using biplane transrectal ultrasound if the tumor was confined to only one prostate lobe. Preoperative PSA values were recorded. Cryoablation was planned to encompass the area of known tumor. PSA values were obtained every 3 months for 2 years and every 6 months thereafter. Potency and continence status was obtained at the same intervals. Routine biopsy was obtained at 1 year. Results. Twenty-one patients had focal cryoablation. Follow-up ranged from 24 to 105 months with a mean of 50 months. Twenty of 21 (95%) patients have stable PSA values with no evidence for cancer, despite 10 patients being at medium to high risk for recurrence. All patients biopsied (n = 19) were negative for tumor. Potency was maintained in 17 of 21 patients (80%). No other complications, including incontinence or fistula formation, were noted. Conclusion. These preliminary results indicate a 'male lumpectomy,' in which the prostate tumor region itself is destroyed, appears to preserve potency in a majority of patients and limits other complications, without compromising cancer control. If these results are confirmed by further studies and long-term follow-up, this treatment approach could have a profound effect on prostate cancer management.

    B cell chronic lymphocytic leukemia (CLL) also called chronic lymphocytic leukemia is a disease of elderly, but in rare cases it can occur in young adults. Majority of patients present with no specific symptoms, and CLL is suspected on the basis of high total and relative lymphocyte counts, discovered on routine blood examination. This patient was referred from medicine outpatient in our institute, Era's Lucknow Medical College & Hospital for routine complete blood count. His total leukocyte count came out to be alarmingly high. The general blood picture and bone marrow examinations were consistent with CLL. On immunophenotyping CD5 and CD23 were positive. His cervical lymph nodes biopsy was reported as a case of CLL/small lymphocytic lymphoma. On his complaint of hazy vision his funduscopy revealed maculopathy. This makes our case a unique and rare one, as maculopathy in a young patient of CLL has not yet been reported from India. PMID:25332614

    Currently, two classes of the computational phantoms have been developed for dosimetry calculation: (1) stylized (or mathematical) and (2) voxel (or tomographic) phantoms describing human anatomy through mathematical surface equations and three-dimensional labeled voxel matrices, respectively. Mathematical surface equations in stylized phantoms provide flexibility in phantom design and alteration, but the resulting anatomical description is, in many cases, not very realistic. Voxel phantoms display far better anatomical realism, but they are limited in terms of their ability to alter organ shape, position, and depth, as well as body posture. A new class of computational phantoms - called hybrid phantoms - takes advantage of the best features of stylized and voxel phantoms - flexibility and anatomical realism, respectively. In the current study, hybrid computational phantoms representing reference 15-year male and female body anatomy and anthropometry are presented. For the male phantom, organ contours were extracted from the University of Florida (UF) 14-year series B male voxel phantom, while for the female phantom, original computed tomography (CT) data from two 14-year female patients were used. Polygon mesh models for the major organs and tissues were reconstructed for nonuniform rational B-spline (NURBS) surface modeling. The resulting NURBS/polygon mesh models representing body contour and internal anatomy were matched to anthropometric data and reference organ mass data provided by the Centers for Disease Control and Prevention (CDC) and the International Commission on Radiation Protection (ICRP), respectively. Finally, two hybrid 15-year male and female phantoms were completed where a total of eight anthropometric data categories were matched to standard values within 4% and organ masses matched to ICRP data within 1% with the exception of total skin. To highlight the flexibility of the hybrid phantoms, 10th and 90th weight percentile 15-year male and female phantoms were further developed from the 50th percentile phantoms through adjustments in the body contour to match the total body masses given in CDC pediatric growth curves. The resulting six NURBS phantoms, male and female phantoms representing their 10th, 50th, and 90th weight percentiles, were used to investigate the influence of body fat distributions on internal organ doses following CT imaging. The phantoms were exposed to multislice chest and abdomen helical CT scans, and in-field organ absorbed doses were calculated. The results demonstrated that the use of traditional stylized phantoms yielded organ dose estimates that deviate from those given by the UF reference hybrid phantoms by up to a factor of 2. The study also showed that use of reference, or 50th percentile, phantoms to assess organ doses in underweight 15-year-old children would not lead to significant organ dose errors (typically less than 10%). However, more significant errors were noted (up to {approx}30%) when reference phantoms are used to represent overweight children in CT imaging dosimetry. These errors are expected to only further increase as one considers CT organ doses in overweight and obese individuals of the adult patient population, thus emphasizing the advantages of patient-sculptable phantom technology.

    Studies examining the sex differences in morbidity and mortality among HIV/AIDS patients have yielded inconsistent results. We conducted a meta-analysis of sex differences in disease progression and mortality among HIV/AIDS patients. Medical literature databases from inception to August 2014 were searched for published observational studies assessing sex differences in immunologic and virologic response, disease progression and mortality among HIV-infected patients. Random effects meta-analyses of 115 eligible studies were conducted to obtain pooled estimates of outcomes and heterogeneity was explored in sub-group analyses. Pooled estimates showed an increased risk of progression to AIDS (relative risk [RR]=1.11,95% CI=1.02-1.21) and all-cause mortality (RR=1.23, 95% CI=1.17-1.29) among males compared to females. All-cause mortality differed by sex only in low and middle income countries. The risk of AIDS-related mortality (RR=1.03, 95% CI=0.82-1.30), immunologic failure (RR=1.19,95% CI: 0.97-1.47), virologic suppression (RR=0.98, 95% CI=0.84-1.14), virologic failure (RR=1.26, 95% CI=0.99-1.61) and the change in CD4 cell count (Weighted mean difference [WMD] = -5.15, 95% CI= -13.57 to 3.28) did not differ by sex. These findings were modified by disease severity, adherence and use of highly active antiretroviral therapy. We conclude that HIV-related disease progression and survival outcomes are poorer in males. PMID:26695132

    Publications about men with eating disorders are still rare. Therefore, in view of the current status of the findings, it seems worthwhile to examine the differences that are empirically verified as well as the relevant common features between the sexes. Based on a representative sample, therefore, male and female patients with eating disorders in inpatient treatment are compared in terms of demographic and clinical variables (symptoms and personality), both at the beginning of treatment and two-and-a-half years after the inpatient treatment, and the findings are discussed with regard to their "gender specificity". The study covered 1,171 patients (male and female) with the diagnosis criteria for anorexia, bulimia and double diagnosis according to DSM-III-R; 33 of them were men. Anorexia cases (342 women and 13 men) and bulimia cases (629 women and 18 men) were compared at the beginning of treatment with the following instruments: Symptom Checklist 90-R; Eating Disorder Inventory; questionnaire for the symptom diagnosis of eating disorders; Freiburger Persönlichkeitsinventar and Narzissmus-Inventar. As a measure of success in the 2.5 year catamnesis (764 women and 20 men), operationalized criteria were defined using the LIFE. The 2.8 % share of men with eating disorders in inpatient treatment again confirms the special nature of this clinical disorder for men. An interesting result is the later onset of illness in male anorexia cases. Coinciding with comparable studies, there are only minor differences in eating behavior, but the differences in body experience are much more pronounced. In bulimic men, there is a higher percentage of homosexuals and they are more satisfied with their body. Anorectic men have a greater gain from the illness, are more concerned about their health and are less performance-minded than female anorectics. The differences that were found clearly indicate that these occur especially in the area of dealing with the body and the significance of the body. One of the reasons why the results in the area of personality and sexual identity are interesting is that they point to differences which definitely appear to be significant, not just between the sexes, but also between male anorexia and bulimia.

    Alcohol-dependent patients have been shown to faster approach than avoid alcohol stimuli on the Approach Avoidance Task (AAT). This so-called alcohol approach bias has been associated with increased brain activation in the medial prefrontal cortex and nucleus accumbens. Cognitive bias modification (CBM) has been used to retrain the approach bias with the clinically relevant effect of decreasing relapse rates one year later. The effects of CBM on neural signatures of approach/avoidance tendencies remain hitherto unknown. In a double-blind placebo-controlled design, 26 alcohol-dependent in-patients were assigned to a CBM or a placebo training group. Both groups performed the AAT for three weeks: in CBM training, patients pushed away 90 percent of alcohol cues; this rate was 50 percent in placebo training. Before and after training, patients performed the AAT offline, and in a 3?T magnetic resonance imaging scanner. The relevant neuroimaging contrast for the alcohol approach bias was the difference between approaching versus avoiding alcohol cues relative to soft drink cues: [(alcohol pull?>?alcohol push)??>?(soft drink pull?>?soft drink push)]. Before training, both groups showed significant alcohol approach bias-related activation in the medial prefrontal cortex. After training, patients in the CBM group showed stronger reductions in medial prefrontal cortex activation compared with the placebo group. Moreover, these reductions correlated with reductions in approach bias scores in the CBM group only. This suggests that CBM affects neural mechanisms involved in the automatic alcohol approach bias, which may be important for the clinical effectiveness of CBM. PMID:25639749

    Background More information is needed about the effect on mortality of continuous positive airway pressure (CPAP) in patients with obstructive sleep apnea (OSA), especially in women. Methods We employed a historical cohort study design, using data from 25,389 patients with a diagnosis of OSA selected from the Danish National Patient Registry for the period 1999–2009. We used Cox proportional hazard function to evaluate the all-cause mortality from OSA in middle-aged and elderly males and females who were treated, or not, with CPAP. Results Female OSA patients had a lower mortality than males, irrespective of whether they received CPAP treatment. CPAP treatment improved survival, as illustrated by the hazard ratio of 0.62 (P<0.001). This effect was dependent on gender: CPAP had no significant effect on 20- to 39-year-old males and females, but the overall mortality in this age group was small. Survival was increased by CPAP in 40- to 59-year-old and ?60-year-old males, but no such effect was observed in females. Positive predictors of survival were young age, female gender, higher educational level, and low 3-year prior comorbidity as estimated by the Charlson Comorbidity Index. Negative predictors for survival were male gender, age ?60 years, no CPAP treatment, prior comorbidity, and low educational level. Conclusion CPAP therapy is associated with reduced all-cause mortality in middle-aged and elderly males, but no significant effect was found in females. PMID:25914563

    Anthropomorphic computational phantoms are computer models of the human body for use in the evaluation of dose distributions resulting from either internal or external radiation sources. Currently, two classes of computational phantoms have been developed and widely utilized for organ dose assessment: (1) stylized phantoms and (2) voxel phantoms which describe the human anatomy via mathematical surface equations or 3D voxel matrices, respectively. Although stylized phantoms based on mathematical equations can be very flexible in regard to making changes in organ position and geometrical shape, they are limited in their ability to fully capture the anatomic complexities of human internal anatomy. In turn, voxel phantoms have been developed through image-based segmentation and correspondingly provide much better anatomical realism in comparison to simpler stylized phantoms. However, they themselves are limited in defining organs presented in low contrast within either magnetic resonance or computed tomography images-the two major sources in voxel phantom construction. By definition, voxel phantoms are typically constructed via segmentation of transaxial images, and thus while fine anatomic features are seen in this viewing plane, slice-to-slice discontinuities become apparent in viewing the anatomy of voxel phantoms in the sagittal or coronal planes. This study introduces the concept of a hybrid computational newborn phantom that takes full advantage of the best features of both its stylized and voxel counterparts: flexibility in phantom alterations and anatomic realism. Non-uniform rational B-spline (NURBS) surfaces, a mathematical modeling tool traditionally applied to graphical animation studies, was adopted to replace the limited mathematical surface equations of stylized phantoms. A previously developed whole-body voxel phantom of the newborn female was utilized as a realistic anatomical framework for hybrid phantom construction. The construction of a hybrid phantom is performed in three steps: polygonization of the voxel phantom, organ modeling via NURBS surfaces and phantom voxelization. Two 3D graphic tools, 3D-DOCTOR and Rhinoceros, were utilized to polygonize the newborn voxel phantom and generate NURBS surfaces, while an in-house MATLAB code was used to voxelize the resulting NURBS model into a final computational phantom ready for use in Monte Carlo radiation transport calculations. A total of 126 anatomical organ and tissue models, including 38 skeletal sites and 31 cartilage sites, were described within the hybrid phantom using either NURBS or polygon surfaces. A male hybrid newborn phantom was constructed following the development of the female phantom through the replacement of female-specific organs with male-specific organs. The outer body contour and internal anatomy of the NURBS-based phantoms were adjusted to match anthropometric and reference newborn data reported by the International Commission on Radiological Protection in their Publication 89. The voxelization process was designed to accurately convert NURBS models to a voxel phantom with minimum volumetric change. A sensitivity study was additionally performed to better understand how the meshing tolerance and voxel resolution would affect volumetric changes between the hybrid-NURBS and hybrid-voxel phantoms. The male and female hybrid-NURBS phantoms were constructed in a manner so that all internal organs approached their ICRP reference masses to within 1%, with the exception of the skin (-6.5% relative error) and brain (-15.4% relative error). Both hybrid-voxel phantoms were constructed with an isotropic voxel resolution of 0.663 mm--equivalent to the ICRP 89 reference thickness of the newborn skin (dermis and epidermis). Hybrid-NURBS phantoms used to create their voxel counterpart retain the non-uniform scalability of stylized phantoms, while maintaining the anatomic realism of segmented voxel phantoms with respect to organ shape, depth and inter-organ positioning.

    Background: C1q nephropathy (C1qN) is an uncommon glomerulopathy with a significant deposition of C1q in mesangium without clinical evidence of lupus.According to the best of our knowledge, there is not any report on coincidence of diabetes mellitus and C1qN. Case presentation: In this report, we presented a 28 years-old-patient with type 1 diabetes and nephrotic range proteinuria, glomerular hematuria and C1q glomerulopathy in renal biopsy. Conclusions: According to the best of our knowledge, there is no previous report about the association between type 1 DM and C1qN. Prevalence of autoimmune disease is higher in type 1 DM and this may explain the relation between DM and C1qN in our patient. PMID:24475450

    Background: The existence of membranous cytoplasmic bodies in biopsied kidney tissues is one of the important findings when considering Fabry disease as the first choice diagnosis. However, there are possible acquired lysosomal diseases associated with pharmacological toxicity, although less attention has been paid to them. Case Presentation: We experienced 3 male patients presenting with proteinuria and specific pathological changes strongly suggesting Fabry disease. We sought detailed clinical and biochemical information to avoid a wrong diagnosis. The patients were examined clinically and pathologically, and plasma ?-galactosidase A (GLA) activity and the globotriaosylsphingosine (lyso-Gb3) concentrations were measured. Electron microscopic examination revealed numerous membranous inclusion bodies in podocytes, and biochemical analysis revealed normal GLA activity and a normal lyso-Gb3 level in plasma, showing that they did not have Fabry disease. They suffered from hyperlipidemia, myeloma, or lupus nephritis. They had received pitavastatin calcium, clarithromycin, loxoprofen and/or prednisolone, and there was no medication history of cationic amphiphilic drugs. Conclusions: In this case series, the etiology of the inclusions was not clarified. However, these cases indicate that careful attention should be paid on diagnosis of patients exhibiting inclusion bodies in kidney cells, and it is important to confirm their past and present illnesses, and medication history as well as to measure the GLA activity and lyso-Gb3 level.

  14. Decisions to use complementary and alternative medicine (CAM) by male cancer patients: information-seeking roles and types of evidence used

    Background Complementary and Alternative Medicine (CAM) is increasingly popular with cancer patients and yet information provision or discussion about CAM by health professionals remains low. Previous research suggests that patients may fear clinicians' 'disapproval' if they raise the subject of CAM, and turn to other sources to acquire information about CAM. However, little empirical research has been conducted into how cancer patients acquire, and, more importantly evaluate CAM information before deciding which CAM therapies to try. Methods Qualitative study, comprising semi-structured interviews with 43 male cancer patients of varying ages, cancer type and stage of illness, 34 of whom had used CAM. They were recruited from a range of NHS and non-NHS settings in Bristol, England. Results As a result of the lack of CAM information from health professionals, men in this study became either 'pro-active seekers' or 'passive recipients' of such information. Their main information resource was the 'lay referral' network of family, friends and acquaintances, especially females. 'Traditional' information sources, including books, magazines, leaflets and the media were popular, more so in fact than the internet. Views on the internet ranged from enthusiasm or healthy scepticism through to caution or disinterest. CAM information was generally regarded as 'empowering' as it broadened treatment and self-care options. A minority of participants were information averse fearing additional choices that might disrupt their fragile ability to cope. There was general consensus that CAM information should be available via the NHS, to give it a 'stamp of approval', which combined with guidance from informed health professionals, could help patients to make 'guided' choices. However, a small minority of these men valued the independence of CAM from the NHS and deliberately sought 'alternative' information sources and treatment options. Men were selective in identifying particular therapies to use and sceptical about others, basing their choices on forms of 'evidence' that were personally meaningful: personal stories of individuals who had been helped by CAM; the long history and enduring popularity of some therapies; the plausibility of the mechanism of action; a belief or trust in individual therapies or their providers; scientific evidence. Scientific evidence ranked low in the men's personal decision-making about CAM, while it was recognised as important for NHS support for CAM. Conclusion These male cancer patients valued the support and guidance of 'trusted individuals' in making choices about CAM. Trusted health professionals could also play a significant role in helping patients to make informed choices. Any such dialogue must, however, acknowledge the different standards of evidence used by patients and clinicians to evaluate the benefits or otherwise of CAM therapies. Such open communication could help to foster an environment of mutual trust where patients are encouraged to discuss their interest in CAM, rather than perpetuate covert, undisclosed use of CAM with its attendant potential hazards.

    Primary cutaneous apocrine gland carcinoma, which is a type of sweat gland carcinoma, is an extremely rare type of cancer. Clinical courses of this type of cancer usually progress slowly but can, occasionally, be associated with rapid progression. This case report describes a 53-year-old Korean man with primary cutaneous apocrine gland carcinoma that arose from an apocrine gland in the areola tissue. The patient visited our hospital because of a large, painful chest wall mass beneath the right nipple. The mass had been present for more than eight years but had grown rapidly over the past few months. The patient was initially diagnosed with a benign cystic mass, and we performed a wide excision with a clear margin and without lymph node dissection. The mass was a well-encapsulated cystic lesion that contained old blood material, and there was no invasion into the surrounding tissue. The final pathology showed that the mass was a primary cutaneous apocrine gland carcinoma that arose from the areola apocrine sweat gland, not from the breast parenchymal tissue. Herein, we report an extremely rare chest wall mass unfamiliar to thoracic surgeons. PMID:26349536

    Although it is known that obesity has a profound effect on x-ray computed tomography (CT) image quality and patient organ dose, quantitative data describing this relationship are not currently available. This study examines the effect of obesity on the calculated radiation dose to organs and tissues from CT using newly developed phantoms representing overweight and obese patients. These phantoms were derived from the previously developed RPI-adult male and female computational phantoms. The result was a set of ten phantoms (five males, five females) with body mass indexes ranging from 23.5 (normal body weight) to 46.4 kg m?2 (morbidly obese). The phantoms were modeled using triangular mesh geometry and include specified amounts of the subcutaneous adipose tissue and visceral adipose tissue. The mesh-based phantoms were then voxelized and defined in the Monte Carlo N-Particle Extended code to calculate organ doses from CT imaging. Chest–abdomen–pelvis scanning protocols for a GE LightSpeed 16 scanner operating at 120 and 140 kVp were considered. It was found that for the same scanner operating parameters, radiation doses to organs deep in the abdomen (e.g., colon) can be up to 59% smaller for obese individuals compared to those of normal body weight. This effect was found to be less significant for shallow organs. On the other hand, increasing the tube potential from 120 to 140 kVp for the same obese individual resulted in increased organ doses by as much as 56% for organs within the scan field (e.g., stomach) and 62% for those out of the scan field (e.g., thyroid), respectively. As higher tube currents are often used for larger patients to maintain image quality, it was of interest to quantify the associated effective dose. It was found from this study that when the mAs was doubled for the obese level-I, obese level-II and morbidly-obese phantoms, the effective dose relative to that of the normal weight phantom increased by 57%, 42% and 23%, respectively. This set of new obese phantoms can be used in the future to study the optimization of image quality and radiation dose for patients of different weight classifications. Our ultimate goal is to compile all the data derived from these phantoms into a comprehensive dosimetry database defined in the VirtualDose software. PMID:22481470

    Trial Design This analysis characterizes the degree of early organ involvement in a cohort of oligo-symptomatic untreated young patients with Fabry disease enrolled in an ongoing randomized, open-label, parallel-group, phase 3B clinical trial. Methods Males aged 5–18 years with complete ?-galactosidase A deficiency, without symptoms of major organ damage, were enrolled in a phase 3B trial evaluating two doses of agalsidase beta. Baseline disease characteristics of 31 eligible patients (median age 12 years) were studied, including cellular globotriaosylceramide (GL-3) accumulation in skin (n = 31) and kidney biopsy (n = 6; median age 15 years; range 13–17 years), renal function, and glycolipid levels (plasma, urine). Results Plasma and urinary GL-3 levels were abnormal in 25 of 30 and 31 of 31 patients, respectively. Plasma lyso-GL-3 was elevated in all patients. GL-3 accumulation was documented in superficial skin capillary endothelial cells (23/31 patients) and deep vessel endothelial cells (23/29 patients). The mean glomerular filtration rate (GFR), measured by plasma disappearance of iohexol, was 118.1 mL/min/1.73 m2 (range 90.4–161.0 mL/min/1.73 m2) and the median urinary albumin/creatinine ratio was 10 mg/g (range 4.0–27.0 mg/g). On electron microscopy, renal biopsy revealed GL-3 accumulation in all glomerular cell types (podocytes and parietal, endothelial, and mesangial cells), as well as in peritubular capillary and non-capillary endothelial, interstitial, vascular smooth muscle, and distal tubules/collecting duct cells. Lesions indicative of early Fabry arteriopathy and segmental effacement of podocyte foot processes were found in all 6 patients. Conclusions These data reveal that in this small cohort of children with Fabry disease, histological evidence of GL-3 accumulation, and cellular and vascular injury are present in renal tissues at very early stages of the disease, and are noted before onset of microalbuminuria and development of clinically significant renal events (e.g. reduced GFR). These data give additional support to the consideration of early initiation of enzyme replacement therapy, potentially improving long-term outcome.

    Observations performed in a subset of patients treated for male pattern hair loss indicate that persistent sexual side effects as well as anxious/depressive symptomatology have been reported even after discontinuation of finasteride treatment. Due to the capability of finasteride to block the metabolism of progesterone (PROG) and/or testosterone (T) we have evaluated, by liquid chromatography-tandem mass spectrometry, the levels of several neuroactive steroids in paired plasma and cerebrospinal fluid (CSF) samples obtained from post-finasteride patients and in healthy controls. At the examination, post-finasteride patients reported muscular stiffness, cramps, tremors and chronic fatigue in the absence of clinical evidence of any muscular disorder or strength reduction. Although severity of the anxious/depressive symptoms was quite variable in their frequency, overall all the subjects had a fairly complex and constant neuropsychiatric pattern. Assessment of neuroactive steroid levels in CSF showed a decrease of PROG and its metabolites, dihydroprogesterone (DHP) and tetrahydroprogesterone (THP), associated with an increase of its precursor pregnenolone (PREG). Altered levels were also observed for T and its metabolites. Thus, a significant decrease of dihydrotestosterone (DHT) associated with an increase of T as well as of 3?-diol was detected. Changes in neuroactive steroid levels also occurred in plasma. An increase of PREG, T, 3?-diol, 3?-diol and 17?-estradiol was associated with decreased levels of DHP and THP. The present observations show that altered levels of neuroactive steroids, associated with depression symptoms, are present in androgenic alopecia patients even after discontinuation of the finasteride treatment.

    Mycoplasma infections are most frequently associated with disease in the urogenital or respiratory tracts and, in most cases, mycoplasmas infect the host persistently. In HIV-infected individuals the prevalence and role of genital mycoplasmas has not been well studied. To investigate the six species of Mycoplasma and the risk factors for infection in Jiangsu province, first-void urine and venous blood samples were collected and epidemiological questionnaires were administered after informed consent. A total of 1541 HIV/AIDS patients were recruited in this study. The overall infection rates of six Mycoplasma species were: Ureaplasma urealyticum (26·7%), Mycoplasma hominis (25·3%), M. fermentans (5·1%), M. genitalium (20·1%), M. penetrans (1·6%) and M. pirum (15·4%). The Mycoplasma infection rate in the unmarried group was lower than that of the married, divorced and widowed groups [adjusted odds ratio (aOR) 1·432, 95% confidence interval (CI) 1·077-1·904, P < 0·05]. The patients who refused highly active antiretroviral therapy (HAART) had a much higher risk of Mucoplasma infection (aOR 1·357, 95% CI 1·097-1·679, P < 0·05). Otherwise, a high CD4+ T cell count was a protective factor against Mycoplasma infection (aOR 0·576, 95% CI 0·460-0·719, P < 0·05). Further research will be required to confirm a causal relationship and to identify risk factors for Mycoplasma infection in HIV/AIDS populations. PMID:25792346

    Antipsychotics sometimes cause sexual dysfunction in people with schizophrenia. The authors report the effectiveness of Saikokaryukotsuboreito (Japanese traditional herbal medicine, Chai-Hu-Jia-Long-Gu-Mu-Li-Tang in Chinese) for antipsychotic-induced sexual dysfunction in two male patients with schizophrenia. The first patient was a 28-year-old man with schizophrenia who suffered erectile dysfunction induced by olanzapine 10?mg/day; the erectile dysfunction significantly improved following the treatment of Saikokaryukotsuboreito 7.5?g/day. The other case was a 43-year-old man with schizophrenia who was receiving fluphenazine decanoate at 50?mg/month and had difficulties in ejaculation; add-on of Saikokaryukotsuboreito 7.5?g/day recovered his ejaculatory function. There has been no report on the effectiveness of Japanese herbal medicine formulations for antipsychotic-induced sexual dysfunction. Although the effectiveness of Saikokaryukotsuboreito needs to be tested in systematic clinical trials, this herbal medicine may be a treatment option to consider for this annoying side effect.

    Men who have been incarcerated experience substantial changes in their sexual behavior after release from jail and prison, and high rates of incarceration may change sexual relationship patterns at a community level. Few studies, however, address how rates of incarceration affect community patterns of sexual behavior, and the implications of those patterns for HIV and STD risk. We describe a "proof of principle" computational model that tests whether rates of male incarceration could, in part, explain observed population-level differences in patterns of sexual behavior between communities with high rates of incarceration and those without. This validated agent-based model of sexual partnership among 20-25 year old heterosexual urban residents in the United States uses an algorithm that incarcerates male agents and then releases them back into the agent community. The results from these model experiments suggest that at rates of incarceration similar to those observed for urban African American men, incarceration can cause an increase in the number of partners at the community level. The results suggest that reducing incarceration and creating a more open criminal justice system that supports the maintenance of inmates' relationships to reduce instability of partnerships for men who are incarcerated may have important sexual health and public health implications. Incarceration is one of many social forces that affect sexual decision-making, and incarceration rates may have substantial effects on community-level HIV and STD risks. PMID:26610077

    Fungaemia due to Paecilomyces lilacinus is generally not considered in AIDS patients because this condition is not categorised as an AIDS-indicator illness. We report a case of a 25-year-old lady who presented to our hospital with Guillain-Barré Syndrome, with the subsequent development of refractory fungaemia, multi-organ failure and disseminated intravascular coagulopathy. Amphotericin B was given as empirical antifungal therapy. HIV screening was reactive and Paecilomyces lilacinus was isolated from her blood. The fungaemia did not resolve after one week of amphotericin B treatment. The addition of itraconazole was also unsuccessful in clearing the fungaemia. Accurate mycological diagnosis is important in the care of AIDS patients with fungaemia because of the risk of treatment failure with empirical therapy. PMID:25097544

    2011-08-01

    PCR amplification and nucleotide sequencing of the ompA gene of Chlamydia trachomatis were used to determine the prevalence and distribution of genotypes in 51 urine and urethral specimens from Greek male patients with urethritis, that were positive by the COBAS Amplicor test. A single C. trachomatis serovar was identified in 43 of the 51 amplified samples. Serovars F and E were the most prevalent (both 12, 28%), followed by D (9, 21%), G (4, 9%), B and K (both 2, 5%) and H and J (both 1, 2%). Over one third of the samples bared a variant ompA genotype that had been previously identified in other areas worldwide. Two results in this study, both observed for the first time, were of particular interest. First, the emergence of the unique variant genotype D/Ep6 (X77364.2) identified in 3 urethral samples. Second, the ompA genotype OCLH196 of the animal pathogen Chlamydophila abortus as well as a 23S rRNA gene fragment of this species detected by the assay ArrayTube™ was found in 7 urethral samples. The implications resulting from this observation for the health of the general population are discussed. PMID:21530642

    Background The majority of previous neuroimaging studies have demonstrated both structural and functional abnormalities in obstructive sleep apnea (OSA). However, few studies have focused on the regional intensity of spontaneous fluctuations during the resting state and the relationship between the abnormal properties and the behavioral performances. In the present study, we employed the amplitude of low-frequency fluctuation (ALFF) method to explore the local features of spontaneous brain activity in OSA patients (OSAs). Methods Twenty-five untreated male severe OSAs and 25 age-matched and years-of-education-matched male good sleepers (GSs) were included in this study. The ALFF method was used to assess the local features of spontaneous brain activity. The mean signal values of the altered ALFF areas were analyzed with receiver operating characteristic curve. Partial correlation analysis was used to explore the relationship between the observed mean ALFF values of the different areas and the behavioral performances. Results Compared with GSs, OSAs had significantly higher scores for body mass index, apnea–hypopnea index, arterial oxygen saturation <90%, arousal index, and Epworth Sleepiness Scale (ESS) score; furthermore, OSAs had significantly lower scores for rapid eye movement sleep and in the Montreal Cognitive Assessment (MoCA). Compared with GSs, OSAs showed significant lower-ALFF areas in the cluster of the right precuneus and bilateral posterior cingulate gyrus, as well as a higher-ALFF area in the left inferior frontal gyrus. The area under the curve values of the lower- and higher-ALFF areas were 0.90 and 0.93, respectively. Further diagnostic analysis exhibited that the sensibility and specificity of the two clusters were 80% and 92%, respectively. The mean signal value of the lower-ALFF cluster displayed significant positive correlations with lowest oxygen saturation (r=0.447, P=0.025) and MoCA score (r =0.405, P=0.045). Conclusion OSAs may involve in a dysfunction in the default mode network and an adaptive compensatory response in the frontal lobe, which reflect the underlying pathophysiology of cognitive impairment.

    Many cross-sectional analyses and longitudinal studies have examined the association between adiposity and pubertal development. In addition, the impact of an increased fat mass on reproduction and fertility in human obese men and in male animal models of obesity has been studied. A trend toward earlier pubertal development and maturation in both sexes has been shown, and the notion that obese boys might progress to puberty at a slower pace than their nonobese peers can no longer be substantiated. Impaired fertility markers and reduced reproductive functions have been observed in obesity. Obesity affects both pubertal development and fertility in men. PMID:26568491

    A 25-year-old woman presented with severe dyspnoea at an emergency care unit on her postpartum day 7. Her O2 saturation level was low. Blood tests showed a high blood D-dimer level; echocardiography showed a high pulmonary artery pressure. Initially, heparin was administered for suspicion of pulmonary embolism. After transfer to the intensive care unit, she suffered respiratory failure. A three-dimensional (3D) reconstruction CT angiography then revealed a giant patent ductus arteriosus. Extracorporeal membrane oxygenation was performed owing to low O2 saturation after ventilator use. After 1?month, she died of multiple organ failure. In postpartum patients with congenital heart disease, a diagnosis of pulmonary embolism should be immediately confirmed by 3D reconstruction CT angiography to rule out patent ductus arteriosus.

In the clinical practice, the desmoid fibromatosis of the lower abdominal wall is a very rare disease. We present a case of a 25-year-old pregnant and discuss diagnostic and therapeutic options by a PubMed literature review. With the knowledge of the prognosis of the desmoid fibromatosis and the respective treatment options including wait and see, complete surgical resection with macroscopically free margins and adjuvant approaches is essential to avoid further interventions and progression of the locally destructive tumor.

    Renal Angiomyolipoma (renal AML) is a benign clonal neoplasm with a incidence of 0.3-3%, occurring as isolated sporadic entity or in association with Tuberous sclerosis (TS) in 80% cases. Multiple, bilateral renal AML are considered diagnostic of Tuberous sclerosis. Wunderlich’s syndrome, a urological emergency is a spontaneous nontraumatic bleeding into subcapsular and or peri-renal space and is a life threatening complication of renal AML occurring in 10% cases which has to be timely diagnosed and treated. Here, we present an unusual case of TS with bilateral, multifocal renal AML in a 25-year-old female who presented with Wunderlich’s syndrome, which is a rare but life threatening complication that has to be suspected, timely diagnosed and treated. We have discussed the importance of early diagnosis, timely treatment, follow up and education of patient and relatives of the possible complications associated. PMID:26435953

    Introduction: Stevens–Johnson syndrome (SJS) is a severe adverse drug reaction that can result in disability and mortality. SJS is defined as having a widespread distribution throughout the whole body surface area with <10% extent of skin detachment and skin lesions. Some drugs, such as carbamazepine, have been reported to have a greater correlation to SJS. Although clozapine use has been mentioned as a risk factor for development of SJS, no report has clearly described the features of SJS as a reaction to clozapine use. Herein, we report the case of a patient presenting SJS after long-term clozapine treatment. Case report: Mr A was a 54-year-old male with a diagnosis of chronic schizophrenia. He was hospitalized in a mental institute and received clozapine 200 mg/day for 2 years, without discomfort or drug side effects. He developed acute-onset mouth edema, multiple oral and ocular ulcers, oral and ocular mucosa swelling, and multiple erythematous skin rashes over his entire body and extremities with hypertension and high fever. SJS was diagnosed after referral to a general hospital. Results The SJS subsided under supportive treatment. Conclusion Accumulated lymphocytes and macrophages in the epidermis and elevated TNF-? might cause an immune reaction and apoptosis and result in the clinical presentation of SJS. Clozapine is believed to modulate the immunologic reaction, and therefore might induce SJS through immunomodulation. This case highlights the importance of considering the possibility of SJS resulting from the use of drugs for which there are no reports of such a severe complication. PMID:25914536

    Background A substantial disadvantage of psychopharmacological treatment of major depressive disorder (MDD) with selective serotonin-reuptake inhibitors (SSRIs) is the impact on sexual dysfunction. The aim of the present study was to investigate whether the oil of Rosa damascena can have a positive influence on SSRI-induced sexual dysfunction (SSRI-I SD) of male patients who are suffering from MDD and are being treated with SSRIs. Method In a double-blind, randomized, and placebo-controlled clinical trial, a total of 60 male patients treated with an SSRI and suffering from MDD (mean age =32 years) and SSRI-I SD were randomly assigned to take either verum (R. damascena oil) or a placebo. Patients completed self-ratings of depression and sexual function at baseline, at 4 weeks later, and at the end of the study, 8 weeks after it started. Results Over time, sexual dysfunction improved more in the verum group than in the control group. Improvements were observed in the verum group from week 4 to week 8. Self-rated symptoms of depression reduced over time in both groups, but did so more so in the verum group than in the control group. Conclusion This double-blind, randomized, and placebo-controlled clinical trial showed that the administration of R. damascena oil ameliorates sexual dysfunction in male patients suffering from both MDD and SSRI-I SD. Further, the symptoms of depression reduced as sexual dysfunction improved. PMID:25834441

    We modified the Imaging Performance Assessment of CT scanners (ImPACT) to evaluate the organ doses and the effective dose based on the International Commission on Radiological Protection (ICRP) Publication 110 reference male/female phantom with the Aquilion ONE ViSION Edition scanner. To select the new CT scanner, the measurement results of the CTDI100,c and CTDI100,p for the 160 (head) and the 320 (body) mm polymethylmethacrylate phantoms, respectively, were entered on the Excel worksheet. To compute the organ doses and effective dose of the ICRP reference male/female phantom, the conversion factors obtained by comparison between the organ doses of different types of phantom were applied. The organ doses and the effective dose were almost identical for the ICRP reference male/female and modified ImPACT. The results of this study showed that, with the dose assessment of the ImPACT, the difference in sex influences only testes and ovaries. Because the MIRD-5 phantom represents a partially hermaphrodite adult, the phantom has the dimensions of the male reference man including testes, ovaries, and uterus but no female breasts, whereas the ICRP male/female phantom includes whole-body male and female anatomies based on high-resolution anatomical datasets. The conversion factors can be used to estimate the doses of a male and a female accurately, and efficient dose assessment can be performed with the modified ImPACT. PMID:25207566

    The present study aimed to assess the influence of long-term therapy with recombinant human erythropoietin (rHuEPO) for 12 months on follitropin (FSH), lutropin (LH), testosterone (TE) and estradiol (E2) serum concentrations in hemodialyzed males with chronic renal failure. Two groups of hemodialyzed males with chronic renal failure were examined. The first one consisted of 20 male patients with uraemia and renal anaemia (haematocrit value < 28%). Eleven of them were treated with rHuEPO for 12 months in order to achieve and maintain a target haematocrit value (Hct) of 30-35% (EPO group). The remaining 9 male patients were only carefully monitored both clinically and biochemically (No-EPO group). Patients of both groups (EPO and No-EPO) were intensively supervised according to the same clinical and biochemical protocol. Before (0) and after 3, 6, 9 and 12 months of the study, blood samples were withdrawn for the estimation of blood haemoglobin concentration, Hct, erythrocyte count, serum ferritin concentration, transferrin saturation and serum concentrations of FSH, LH, TE and E2. In patients of the EPO group a marked increase while of the No-EPO group, a slight, but statistically significant increase of the Hct value was found after 9 and 12 months and of E2 concentration after 3, 6, 9 and 12 months of clinical monitoring. In contrast in patients of the EPO group a statistically significant decrease of serum FSH and LH concentrations (during the first 9 months of treatment) and an increase of serum TE and E2 concentrations was observed. From results obtained in this study the following conclusions may be drawn: 1. The degree of anaemia does influence significantly the hormonal profile of the pituitary-gonadal axis in haemodialyzed males with chronic renal failure. 2. rHuEPO therapy for 12 months does exert a significant, although transitory (confined to the first 6-9 months of therapy) suppressive effect on serum follitropin and lutropin levels but increases serum testosterone and estradiol levels in these patients. 3. Alterations of both haematological parameters and of hormone serum levels of the pituitary-gonadal axis observed in EPO treated patients do not seem to be due only to the administration of this hormone.

    Clear evidence shows that many men and women would welcome new male methods of contraception, but none have become available. The hormonal approach is based on suppression of gonadotropins and thus of testicular function and spermatogenesis, and has been investigated for several decades. This approach can achieve sufficient suppression of spermatogenesis for effective contraception in most men, but not all; the basis for these men responding insufficiently is unclear. Alternatively, the non-hormonal approach is based on identifying specific processes in sperm development, maturation and function. A range of targets has been identified in animal models, and targeted effectively. This approach, however, remains in the pre-clinical domain at present. There are, therefore, grounds for considering that safe, effective and reversible methods of contraception for men can be developed. PMID:24947599

    2014-01-01

    Male face lifting is the cosmetic surgery which has witnessed the greatest rise in demand in recent years. A result of social evolution and development of non-surgical techniques for facial rejuvenation, this intervention represents a real challenge for the surgeon who operates mainly on women. Man has specific characteristics which include differences in the aging process, and a multitude of anatomical and psychosocial factors that will require adjustments in the patient's overall care. Indeed, the adaptation of the conventional technique of the female facelift would lead to an unnatural result, not satisfactory for the patient. To best meet the demands of the male patient, the surgeon must take into account the male facial characteristics in order to optimize the results. PMID:26521365

    Westwood, Michael; Pinzon, Jorge

    2008-01-01

    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

A 9-year-old male patient with Goltz syndrome presented with typical skin lesions along with progressive dimness of vision and mental retardation since birth. It is inherited in an X-linked dominant fashion and is normally lethal in male patients, and so very few male patients, like the index case, have been reported. PMID:23119212

    PubMed Central

    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

    Appearance of the male genitalia is linked with self-esteem and sexual identity. Aesthetic surgery of the male genitalia serves to correct perceived deficiencies as well as physical deformities, which may cause psychological distress. Attention to patient motivation for surgery and to surgical technique is key to achieving optimal results. In this review, the authors describe aesthetic surgical techniques for treatment of penile and scrotal deficiencies. They also discuss techniques for revision in patients with previous surgery.

    Introduction Spermatogenesis is a highly complex process involving several thousand genes, only a minority of which have been studied in infertile men. In a previous study, we identified a number of Copy Number Variants (CNVs) by high-resolution array-Comparative Genomic Hybridization (a-CGH) analysis of the X chromosome, including 16 patient-specific X chromosome-linked gains. Of these, five gains (DUP1A, DUP5, DUP20, DUP26 and DUP40) were selected for further analysis to evaluate their clinical significance. Materials and Methods The copy number state of the five selected loci was analyzed by quantitative-PCR on a total of 276 idiopathic infertile patients and 327 controls in a conventional case-control setting (199 subjects belonged to the previous a-CGH study). For one interesting locus (intersecting DUP1A) additional 338 subjects were analyzed. Results and Discussion All gains were confirmed as patient-specific and the difference in duplication load between patients and controls is significant (p?=?1.65×10?4). Two of the CNVs are private variants, whereas 3 are found recurrently in patients and none of the controls. These CNVs include, or are in close proximity to, genes with testis-specific expression. DUP1A, mapping to the PAR1, is found at the highest frequency (1.4%) that was significantly different from controls (0%) (p?=?0.047 after Bonferroni correction). Two mechanisms are proposed by which DUP1A may cause spermatogenic failure: i) by affecting the correct regulation of a gene with potential role in spermatogenesis; ii) by disturbing recombination between PAR1 regions during meiosis. This study allowed the identification of novel spermatogenesis candidate genes linked to the 5 CNVs and the discovery of the first recurrent, X-linked gain with potential clinical relevance.

    As a result of injury caused by chronic gastroesophageal reflux, Barrett's esophagus with high-grade dysplasia and esophageal adenocarcinoma are rapidly increasing problems in the United States. The current standard of care involves esophagectomy, a procedure associated with a high morbidity, a negative impact on long term quality of life, and a mortality rate of 1–6 percent. An entirely endoscopic technique for circumferential, long segment en bloc removal of the mucosa and submucosa with subsequent placement of a biologic scaffold material that promotes a constructive remodeling response and minimizes stricture is described herein. The results of this approach are reported for five patients with 4–24-month follow-up. Restoration of normal mature, K4+/K14+, squamous epithelium, and return to a normal diet without significant dysphagia is reported for all patients. Two of five patients show a small focus of recurrent Barrett's esophagus at the gastroesophageal junction, but the entire length and circumference of the reconstituted esophageal mucosa remains free of disease. This experience provides evidence that a regenerative medicine approach may, for the first time, enable aggressive endoscopic resection of early stage neoplasia without the need for esophagectomy and its associated complications.

    Introduction Sexuality is an important part of people’s physical and mental health. Patients with heart disease often suffer from sexual dysfunction. Sexual dysfunction has a negative impact on quality of life and well-being in persons with heart disease, and sexual dysfunction is associated with anxiety and depression. Treatment and care possibilities seem to be lacking. Studies indicate that non-pharmacological interventions such as exercise training and psychoeducation possess the potential of reducing sexual dysfunction in patients with heart disease. The CopenHeartSF trial will investigate the effect of a comprehensive sexual rehabilitation programme versus usual care. Methods and analysis CopenHeartSF is an investigator-initiated randomised clinical superiority trial with blinded outcome assessment, with 1:1 central randomisation to sexual rehabilitation plus usual care versus usual care alone. Based on sample size calculations, 154 male patients with impaired sexual function due to implantable cardioverter defibrillator or ischaemic heart disease will be included from two university hospitals in Denmark. All patients receive usual care and patients allocated to the experimental intervention group follow a 12-week sexual rehabilitation programme consisting of an individualised exercise programme and psychoeducative consultation with a specially trained nurse. The primary outcome is sexual function measured by the International Index of Erectile Function. The secondary outcome measure is psychosocial adjustment to illness by the Psychosocial Adjustment to Illness Scale, sexual domain. A number of explorative analyses will also be conducted. Ethics and dissemination CopenHeartSF is approved by the regional ethics committee (no H-4-2012-168) and the Danish Data Protection Agency (no 2007-58-0015) and is performed in accordance with good clinical practice and the Declaration of Helsinki in its latest form.

    2012-01-01

    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. PMID:23286540

    Objective Cigarette smoking is an important modifiable risk factor for cardiovascular diseases. However, the effect of smoking and its cessation on glycemic control in diabetic patients has not been fully examined yet. The aim of the present study was to examine the association of smoking status with glycemic level and markers of insulin resistance and secretion in patients with type 2 diabetes mellitus. Research Design and Methods A total of 2,490 Japanese male patients with type 2 diabetes mellitus aged ?20 years were divided according to smoking status, amount of cigarettes smoked and years since quitting. The associations with glycemic level and markers of insulin resistance and secretion were examined cross-sectionally. Results HbA1c levels increased progressively with increases in both number of cigarettes per day and pack-years of cigarette smoking compared with never smokers (P for trend = 0.001 and <0.001, respectively), whereas fasting plasma glucose did not. On the other hand, HbA1c, but not fasting plasma glucose, decreased linearly with increase in years after smoking cessation (P for trend <0.001). These graded relationships persisted significantly after controlling for the confounders, including total energy intake, current drinking, regular exercise, depressive symptoms, and BMI. In addition, a homeostasis model assessment of insulin resistance and high-sensitivity C-reactive protein also showed similar trends. Conclusions Smoking and its cessation showed dose- and time-dependent relationship with glycemic control and insulin resistance in patients with type 2 diabetes mellitus. These findings may highlight the importance of smoking cessation in the clinical management of diabetes mellitus. PMID:25822499

    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. PMID:25917068

    Insurance coverage has increased among young adults due to the 2010 dependent coverage provision of the Affordable Care Act. However, little is known about the provision's effects on clinical outcomes and insurance coverage of patients with trauma – the most frequent cause of death and physical disability among young adults. Using the 2007-2012 National Trauma Databank, we conducted a difference-in-differences analysis of coverage rates among 19-25 year-old trauma patients, compared to 26-34 year-old controls, and examined trauma-relevant outcomes by patient, injury, and hospital characteristics. We found a 3.4 percentage point decrease in uninsured status among younger trauma patients following the policy change, concentrated among nonminority patients, those with less severe injuries, and those with lower trauma-related mortality risk. We did not detect significant changes in intensive care use or overall mortality. The heterogeneous coverage impact of this provision on high- versus low-risk trauma patients has implications for future efforts to expand coverage. PMID:25561653

    We detail here the clinical description and the family genetic study of a male patient with global developmental delay, disruptive and obsessive behaviors and minor dysmorphic features and a combination of two rare genetic variants: a maternally inherited 16p13.11-p12.3 duplication and a de novo 12p12.1 deletion affecting SOX5. The 16p13.11 microduplication has been implicated in several neurodevelopmental and behavioral disorders and is characterized by variable expressivity and incomplete penetrance. The causes of this variation in phenotypic expression are not fully clear, representing a challenge in genetic diagnosis and counseling. However, several authors have proposed the two-hit model as one of the underlying mechanisms for this phenotypic heterogeneity. Our data could also support this two-hit model in which the 16p13.11-p12.3 duplication might contribute to the phenotype, not only as a single event but also in association with the SOX5 deletion. The SOX5 gene plays important roles in various developmental processes and has been associated with several neurodevelopmental disorders, mainly intellectual disability, developmental delay and language and/or speech delay as well as with behavior problems and dysmorphic features. However, many of the physical features and behavioral manifestations as well as language deficiencies present in our patient are consistent with those previously reported for SOX5 deletions. Patients carrying multiple genomic variants, as the one presented here, illustrate the difficulty in analyzing genotypes when the contribution of each variant results in overlapping phenotypes and/or, alternatively, in the modification of the clinical manifestations defined by the coexisting variant.

    OBJECTIVES: Describe rates of adherence for sickle cell disease (SCD) medications, identify patient and medication characteristics associated with nonadherence, and determine the effect of nonadherence and moderate adherence (defined as taking 60%–80% of doses) on clinical outcomes. METHODS: In February 2012 we systematically searched 6 databases for peer-reviewed articles published after 1940. We identified articles evaluating medication adherence among patients <25 years old with SCD. Two authors reviewed each article to determine whether it should be included. Two authors extracted data, including medication studied, adherence measures used, rates of adherence, and barriers to adherence. RESULTS: Of 24 articles in the final review, 23 focused on 1 medication type: antibiotic prophylaxis (13 articles), iron chelation (5 articles), or hydroxyurea (5 articles). Adherence rates ranged from 16% to 89%; most reported moderate adherence. Medication factors contributed to adherence. For example, prophylactic antibiotic adherence was better with intramuscular than oral administration. Barriers included fear of side effects, incorrect dosing, and forgetting. Nonadherence was associated with more vaso-occlusive crises and hospitalizations. The limited data available on moderate adherence to iron chelation and hydroxyurea indicates some clinical benefit. CONCLUSIONS: Moderate adherence is typical among pediatric patients with SCD. Multicomponent interventions are needed to optimally deliver life-changing medications to these children and should include routine monitoring of adherence, support to prevent mistakes, and education to improve understanding of medication risks and benefits.

    We report on a patient with type 1 diabetes mellitus who presented with recurrent episodes of hypoglycemia and a marked reduction in her daily insulin requirements after introduction of fluoxetine. This 25-year-old Caucasian woman had been followed up at the outpatient clinic for type 1 diabetes mellitus and pre-pregnancy care. She used a continuous subcutaneous insulin infusion with lispro and her daily insulin dose was 0.5 IU/kg per day. She had no chronic diabetic complications or hypoglycemia unawareness. Fluoxetine at a daily dose of 20 mg had been started because of depressive symptoms and within one week, she presented recurrent hypoglycemic episodes that prompted a progressive reduction in the insulin dose down to 0.3 IU/kg per day. The reduced insulin requirements continued during the period of fluoxetine treatment while glycated hemoglobin remained stable. She had no concurrent additional cause to explain the reduced insulin requirements. After fluoxetine was stopped, insulin requirements progressively increased and returned to the patient´s usual dose. PMID:24303494

    2004-06-01

    The objective of this report is to assess in men whether exercise affects the estimated age-related increase in adiposity, and contrariwise, whether age affects the estimated exercise-related decrease in adiposity. Cross-sectional analyses of 64,911 male runners who provided data on their body mass index (97.6 percent), waist (91.1 percent), hip (47.1 percent), and chest circumferences (77.9 percent). Between 18 to 55 years old, the decline in BMI with weekly distance run (slope+-SE) was significantly greater in men 25-55 years old (slope+-:-0.036+-0.001 kg/m2 per km/wk) than in younger men (-0.020+-0.002 kg/m 2 per km/wk). Declines in waist circumference with running distance were also significantly greater in older than younger men (P<10-9 for trend),i.e., the slopes decreased progressively from -0.035+-0.004 cm per km/wk in 18-25 year old men to -0.097+-0.003 cm per km/wk in 50-55 year old men. Increases in BMI with age were greater for men who ran under 16km/wk than for longer distance runners. Waist circumference increased with age at all running levels, but the increase appeared to diminish by running further (0.259+-0.015 cm per year if running<8 km/wk and 0.154+-0.003 cm per year for>16 km/wk). In men over 50 years old, BMI declined -0.038+-0.001 kg/m2 per km/wk run when adjusted for age and declined -0.054+-0.003 kg/m2 (increased 0.021+-0.007 cm) per year of age when adjusted for running distance. Their waist circumference declined-0.096+-0.002 cm per km/wk run when adjusted for age and increased 0.021+-0.007 cm per year of age when adjusted for running distance. These cross-sectional data suggest that age and vigorous exercise interact with each other in affecting mens adiposity, and support the proposition that vigorous physical activity must increase with age to prevent middle-age weight gain. We estimate that a man who ran 16 km/wk at age 25 would need to increase their weekly running distance by 65.7 km/wk by age 50 in order to maintain his same waist circumference.

    Summary: Cancer of a male breast represents less than 1% of all breast cancer. As with to female patients, mastectomy in men creates a substantial emotional burden. Breast reconstruction may improve the patient’s psychological well-being, compliance with adjuvant treatments, and overall outcome. However, due to the unique anatomy of the male breast, standard reconstructive strategies using anatomic or prosthetic modalities are not entirely applicable. We describe a case of a 68-year-old male patient who underwent successful unilateral breast reconstruction solely with fat grafting technique. PMID:25506540

    The evaluation of the subfertile male starts with the basic history and physical examination, which often provide indication of probable cause. Aside from analysis of properly collected semen, most cases require very few tests. Etiology can be classified as pretesticular, testicular, and post-testicular. Treatment can be more specific if a definite cause is found. Unfortunately, about 25% of patients are idiopathic, and non-specific treatments generally yield unacceptably low conception rates. Improvement will occur as more becomes known, through animal research and clinical application, about the physiology of spermatogenesis and the pathological processes that can affect it.

    Autoimmune polyendocrine syndrome type 1 (APS1), a monogenic disorder caused by AIRE gene mutations, features multiple autoimmune disease components. Infertility is common in both males and females with APS1. Although female infertility can be explained by autoimmune ovarian failure, the mechanisms underlying male infertility have remained poorly understood. We performed a proteome-wide autoantibody screen in APS1 patient sera to assess the autoimmune response against the male reproductive organs. By screening human protein arrays with male and female patient sera and by selecting for gender-imbalanced autoantibody signals, we identified transglutaminase 4 (TGM4) as a male-specific autoantigen. Notably, TGM4 is a prostatic secretory molecule with critical role in male reproduction. TGM4 autoantibodies were detected in most of the adult male APS1 patients but were absent in all the young males. Consecutive serum samples further revealed that TGM4 autoantibodies first presented during pubertal age and subsequent to prostate maturation. We assessed the animal model for APS1, the Aire-deficient mouse, and found spontaneous development of TGM4 autoantibodies specifically in males. Aire-deficient mice failed to present TGM4 in the thymus, consistent with a defect in central tolerance for TGM4. In the mouse, we further link TGM4 immunity with a destructive prostatitis and compromised secretion of TGM4. Collectively, our findings in APS1 patients and Aire-deficient mice reveal prostate autoimmunity as a major manifestation of APS1 with potential role in male subfertility. PMID:26084804

    2015-01-01

    Reproductive dysfunction and malignancies related to the male gender represent a serious health concern, whose incidence has significantly risen over the past years. Prior to treatment, testicular or prostate cancer patients often display poor semen characteristics similar to subfertile or infertile patients. This fact is underscored by cases where the malignancy is often diagnosed in males who undergo a general fertility screening. This review aims to examine the associations between male infertility and reproductive cancers focusing on common etiologies and biological mechanisms underlining these pathologies. Furthermore, we discuss compelling epidemiological data hypothesizing that male reproductive failure may act as a precursor of future andrological malignancies, including testicular or prostate cancer, thus providing a stimulus for a more specific research in male reproductive health and emphasizing the importance of this relation for physicians taking care of male patients with a reproductive disease.

    Objective The purpose of this case report is to describe the use of chiropractic care for a patient with neurogenic heterotopic ossification of the anterior longitudinal ligament in the cervical spine and soft tissues of the right hip after a traumatic brain injury and right femur fracture. Clinical Features A 25-year-old military officer was referred to a hospital-based chiropractic clinic with complaints of pain and stiffness of the neck and back along with reduced respiratory excursions that began several months after a motor vehicle accident in which he had a traumatic brain injury. The patient had a fractured right femur from the accident, which had since been treated surgically, but had complications of heterotopic ossification in the soft tissues of the hip. His overall pain level was 3 of 10 on a verbal pain scale during use of oxycodone HCL/acetaminophen. Chest excursion was initially measured at .5 cm. Intervention and Outcome With the intent to restore respiratory chest motion and to reduce the patient's back and neck pain, the patient was placed on a program of chiropractic and myofascial manipulation, exercise therapy, and respiratory therapy. After a year of care, the patient rated overall pain at 3 of 10 verbal pain scale level but was no longer taking medications for pain and an increase in respiratory chest excursions measured at 3.5 cm. Conclusion This case demonstrated that chiropractic treatment provided benefit to a patient with heterotopic ossification concurrent with musculoskeletal pain. PMID:25435839

    Although the male reproductive function is impaired in about half of infertile couples, the evaluation of male infertility is underrated or neglected even today. In addition to a physical examination and imaging techniques, semen analysis as well as endocrine and genetic analyses should be part of the routine investigation. Few disorders have become subjects of rational treatment of the infertile male, even though, as examples, hypogonadotropic hypogonadism is treatable by gonadotropins and obstructive azoospermia by reconstructive surgery. Early treatment of maldescended testes and sexually transmitted diseases can prevent infertility. Similar pregnancy rates from patients with varicocele following surgery or counseling demonstrate the important role of the physician in the treatment of infertility. In the age of evidence-based medicine, most empirical treatments have been demonstrated to be ineffective. Instead, symptomatic treatment by assisted reproductive techniques has become a central tool to overcome otherwise untreatable male infertility. PMID:24079474

    Major difficulties exist in the accurate and meaningful diagnosis of male reproductive dysfunction, and our understanding of the epidemiology and etiology of male infertility has proven quite complex.The numerous spermatozoa produced in mammals and other species provides some degree of protection against adverse environmental conditions represented by physical and chemical factors that can reduce reproductive function and increase gonadal damage even resulting in testicular cancer or congenital malformations. The wide fluctuations of sperm production in men, both geographical and temporal, may reflect disparate environmental exposures, occurring on differing genetic backgrounds, in varying psychosocial conditions, and leading to the diversified observed outcomes.Sperm analysis is still the cornerstone in diagnosis of male factor infertility, indeed, individually compromised semen paramaters while adequately address therapeutic practices is progressively flanked by additional tests. Administration of drugs, IUI, correction of varicocele, and, to a certain extent, IVF although they may not be capable of restoring fertility itself often result in childbearing. PMID:24782020

    Introduction: Paraquat is a widely used nitrogen-based herbicide which is lethal and causes multi-organ failure by accumulation in cells, which subsequently leads to death. Case Presentation: The present case report introduced a 25-year-old male with nausea, vomiting, and severe substernal burning sensation after incidentally ingestion of a large amount of paraquat. The treatment of the patient with antioxidants (N-acetylcysteine and vitamin E) and hemodialysis started immediately after arriving to the hospital. Conclusions: Immediate and adequate use of antioxidants and hemodialysis has an undeniable and important role in survival of patients after ingestion of a large amount of paraquat. PMID:26568853

    Sparganosis mansoni is a kind of parasitic infective disease, rarely seen in clinic. A case of sparganosis mansoni is reported in this article. The patient was a 25-year-old male, who came to Xiangya Hospital on September 26, 2007 because of a mass in the left cheek. A white tape-like body was found during the operation and recognized to be a live parasite. Enzyme linked immunosorbent assay of the serum revealed positivity against Spirometra mansoni. The final identification proved that the white tape-like body was Sparganum mansoni. The disease of this patient was caused by eating raw flesh of frogs infected with the Sparganum mansoni.

    Purpose Adolescents and young adults (AYAs) diagnosed with cancer face numerous physical, psychosocial, and practical challenges. This article describes the health-related quality of life (HRQOL) and associated demographic and health-related characteristics of this developmentally diverse population. Patients and Methods Data are from the Adolescent and Young Adult Health Outcomes and Patient Experience (AYA HOPE) study, a population-based cohort of 523 AYA patients with cancer, ages 15 to 39 years at diagnosis from 2007 to 2009. Comparisons are made by age group and with general and healthy populations. Multiple linear regression models evaluated effects of demographic, disease, health care, and symptom variables on multiple domains of HRQOL using the Pediatric Quality of Life Inventory (PedsQL) and the Short-Form Health Survey 12 (SF-12). Results Overall, respondents reported significantly worse HRQOL across both physical and mental health scales than did general and healthy populations. The greatest deficits were in limitations to physical and emotional roles, physical and social functioning, and fatigue. Teenaged patients (ages 15 to 17 years) reported worse physical and work/school functioning than patients 18 to 25 years old. Regression models showed that HRQOL was worse for those in treatment, with current/recent symptoms, or lacking health insurance at any time since diagnosis. In addition, sarcoma patients, Hispanic patients, and those with high school or lower education reported worse physical health. Unmarried patients reported worse mental health. Conclusion Results suggest that AYAs with cancer have major decrements in several physical and mental HRQOL domains. Vulnerable subgroups included Hispanic patients, those with less education, and those without health insurance. AYAs also experienced higher levels of fatigue that were influenced by current symptoms and treatment. Future research should explore ways to address poor functioning in this understudied group.

  9. Large and forgotten in rural Australia: assessment, attitudes and possible approaches to losing weight in young adult males

    2014-01-01

    Background Young Adult Males (YAMs) in rural Australia are poorly studied with respect to overweight and obesity. Firstly, we explored the feasibility of recruiting 17–25 year old YAMs to obtain baseline data on overweight and obesity rates, socio-demographics, nutrition, exercise and mobile phone usage. Secondly, we explored the views of YAMs with a waist measurement over 94 cm about using mobile phone text messages to promote weight loss and incentives to promote healthy lifestyles. Methods A two-staged, mixed-methods approach was used to study obesity and overweight issues in Dubbo, a regional city in New South Wales, Australia. In Phase I, socio-demographic, health behaviour and mobile phone usage data were collected using a questionnaire and anthropometric data collected by direct measurement. In Phase II, YAMs’ views were explored by focus group discussion using a semi-structured questionnaire. Results Phase I (145 participants): mean Body Mass Index (BMI) 25.06?±?5.01; mean waist circumference 87.4?±?15.4 cm. In total, 39.3% were obese (12.4%) or overweight (26.9%) and 24.1% had an increased risk of metabolic complications associated with obesity. 135 (93.1%) owned a mobile phone and sent on average 17?±?25 text messages per day and received 18?±?24. Phase II (30 participants): YAMs acknowledged that overweight and obesity was a growing societal concern with many health related implications, but didn’t feel this was something that affected them personally at this stage of their lives. Motivation was therefore an issue. YAMs admitted that they would only be concerned about losing weight if something drastic occurred in their lives. Text messages would encourage and motivate them to adopt a healthy lifestyle if they were individually tailored. Gym memberships, not cash payments, seem to be the most favoured incentive. Conclusion There is a clear need for an effective health promotion strategy for the almost 40% overweight or obese Dubbo YAMs. The high rate of text message usage makes it feasible to recruit YAMs for a prospective study in which personalized text messages are used to promote healthy behaviours. It may be important to target motivation specifically in any weight-related intervention in this group with incentives such as gym membership vouchers. PMID:24612872

    Metastases to the breast are uncommon, accounting for 0.5% of breast tumors, and most of them are originated from lymphoma, melanoma and carcinomas of various organs. Alveolar soft part sarcoma (ASPS) is a very rare neoplasm that is usually found in the lower extremities. Lungs are the common site of dissemination and may represent initial manifestation of disease. We report a clinically unsuspected case of ASPS presenting as a breast metastasis in a 25-year-old woman. The patient’s medical history was notable for a thyroid cancer treated by surgery and radioiodine ablation 2 years ago. Core needle biopsy of slowly growing breast mass yielded polygonal cells with abundant eosinophilic cytoplasm arranged into solid pattern. Differential diagnosis between apocrine cell carcinoma, paraganglioma, granular cell tumor, neuroendocrine carcinoma, ASPS and metastatic hepatocellular and renal cell carcinoma was rendered by immunohistochemistry. Strong nuclear TFE3 immunoreactivity confirmed a diagnosis of ASPS. Retrospectively a primary tumor was found in the thigh. Most likely, ASPS and thyroid cancer in the patient were growing synchronously and independently. PMID:26464747

    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

    2015-01-01

    The circumcision of newborn males in Canada has become a less frequent practice over the past few decades. This change has been significantly influenced by past recommendations from the Canadian Paediatric Society and the American Academy of Pediatrics, who both affirmed that the procedure was not medically indicated. Recent evidence suggesting the potential benefit of circumcision in preventing urinary tract infection and some sexually transmitted infections, including HIV, has prompted the Canadian Paediatric Society to review the current medical literature in this regard. While there may be a benefit for some boys in high-risk populations and circumstances where the procedure could be considered for disease reduction or treatment, the Canadian Paediatric Society does not recommend the routine circumcision of every newborn male.

    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.

  14. 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. PMID:25916694

    Most individuals with the rare 46,XX male {open_quotes}syndrome{close_quotes} arise due to an unequal interchange between Xp and Yp termini during paternal meiosis. The pattern of Y-sequences in these patients varies considerably, but very few cases have been reported showing only SRY. The phenotype in these patients is also variable ranging from severe impairment of the external genitalia through hypospadias and/or cryptorchidism to occasional normal male phenotype. We report a Mexican 46,XX male patient without genital ambiguities in whom DNA analysis showed the presence of SRY and the absence of ZFY. We conclude that in this case SRY alone was enough for complete male sexual differentiation. 25 refs., 1 fig.

    Gastric cavernous hemangioma is a relatively rare benign gastric disease. Here we report the case of a 25-year-old male patient who had been admitted complaining of epigastric pain and hematemesis. Preoperative imaging indicated that the mass lesion palpated in the epigastric region was a probable mesenchymal tumor of gastric origin. Due to the hypervascular nature and submucosal localization of the mass, we did not obtain definitive preoperative diagnosis by endoscopic biopsy. The histologic diagnosis of cavernous hemangioma was confirmed by post-resection histopathologial evaluation of the mass. PMID:23024741

    2014-08-01

    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. PMID:24578106

    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. PMID:26475094

    2010-01-01

    Male hypogonadism is a condition in which the body does not produce enough of the testosterone hormone; the hormone that plays a key role in masculine growth and development during puberty. There is a clear need to increase the awareness of hypogonadism throughout the medical profession, especially in primary care physicians who are usually the first port of call for the patient. Hypogonadism can significantly reduce the quality of life and has resulted in the loss of livelihood and separation of couples, leading to divorce. It is also important for doctors to recognize that testosterone is not just a sex hormone. There is an important research being published to demonstrate that testosterone may have key actions on metabolism, on the vasculature, and on brain function, in addition to its well-known effects on bone and body composition. This article has been used as an introduction for the need to develop sensitive and reliable assays for sex hormones and for symptoms and treatment of hypogonadism. PMID:22247861

    2008-11-01

    In order to study male gonadal function in Noonan syndrome, clinical and laboratory data, including inhibin B, were gathered in nine pubertal males diagnosed with Noonan syndrome. Bilateral testicular maldescent was observed in four, and unilateral cryptorchidism occurred in two. Puberty was delayed in three patients. Luteinising hormone (LH) levels were normal in all patients in our series, while follicle stimulating hormone (FSH) levels were raised in seven. Inhibin B was low in six males and just above the lower limit of normal in two. Importantly, all three men with normal testicular descent displayed signs of Sertoli cell dysfunction, indicating, in contrast to earlier reports, that bilateral cryptorchidism does not seem to be the main contributing factor to impairment of testicular function in Noonan syndrome. These findings suggest different mechanisms of disturbance in male gonadal function, which is frequently associated with Sertoli dysfunction. PMID:19189703

    Approximately 1% of all men in the general population suffer from azoospermia, and azoospermic men constitute approximately 10 to 15% of all infertile men. Thus, this group of patients represents a significant population in the field of male infertility. A thorough medical history, physical examination and hormonal profile are essential in the evaluation of azoospermic males. Imaging studies, a genetic workup and a testicular biopsy (with cryopreservation) may augment the workup and evaluation. Men with nonobstructive azoospermia should be offered genetic counseling before their spermatozoa are used for assisted reproductive techniques. This article provides a contemporary review of the evaluation of the azoospermic male. PMID:23503952

    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.

  7. Reduced male fertility in childhood cancer survivors

    PubMed Central

    Lee, Sun Hee

    2013-01-01

    With advances in cancer treatment, more pediatric cancer patients have increased their life expectancy. Because cancer-related therapy causes various physical and psychological problems, many male survivors experience later problems with thyroid and sexual functions, and with growth. As outcomes have improved, more survivors need to maintain their reproductive function to maximize their long-term quality of life. Cancer and cancer-related treatment can impair fertility by damage to the testes, to the hypothalamic-pituitary-gonadal axis, or to the genitourinary organs. Prior radiation therapy to the testes, the use of alkylating agents, and central hypogonadism further impair fertility in male survivors of childhood cancer. Following any course of chemotherapy, peripubertal maturation, any testicular volume changes, and symptoms of androgen deficiency should be monitored systematically. If patients request fertility testing, spermatogenesis status can be evaluated either directly by semen analysis or indirectly by determination of the levels of testosterone/gonadotropins and by monitoring any changes in testicular volume. According to the patient's condition, semen cryopreservation, hormonal therapy, or assisted reproduction technologies should be provided. PMID:24904872

    Purpose: Knowledge of sexual problems after pre- or postoperative radiotherapy (RT) with 50 Gy for rectal cancer is limited. In this study, we aimed to compare self-rated sexual functioning in irradiated (RT+) and nonirradiated (RT-) male patients at least 2 years after surgery for rectal cancer. Methods and Materials: Patients diagnosed with rectal cancer from 1993 to 2003 were identified from the Norwegian Rectal Cancer Registry. Male patients without recurrence at the time of the study. The International Index of Erectile Function, a self-rated instrument, was used to assess sexual functioning, and serum levels of serum testosterone were measured. Results: Questionnaires were returned from 241 patients a median of 4.5 years after surgery. The median age was 67 years at survey. RT+ patients (n = 108) had significantly poorer scores for erectile function, orgasmic function, intercourse satisfaction, and overall satisfaction with sex life compared with RT- patients (n = 133). In multiple age-adjusted analysis, the odds ratio for moderate-severe erectile dysfunction in RT+ patients was 7.3 compared with RT- patients (p <0.001). Furthermore, erectile dysfunction of this degree was associated with low serum testosterone (p = 0.01). Conclusion: RT for rectal cancer is associated with significant long-term effects on sexual function in males.

  13. Fertility preservation in the male with cancer.

    PubMed

    Williams, Daniel H

    2013-08-01

    This article reviews the current concepts, recommendations, and principles of fertility preservation in men with cancer. Obstacles to sperm banking are addressed, as well as future directions for fertility-preserving technologies. All cancer therapies--chemotherapy, radiation, and surgery--are potential threats to a man's reproductive potential. Additionally, cancer itself can impair spermatogenesis. Thus, sperm cryopreservation prior to initiating life-saving cancer treatment offers men and their families the best chances to father biologically-related children and should be offered to all men with cancer before treatment. Better patient and provider education, as well as deliberate, coordinated strategies at comprehensive cancer care centers, are necessary to make fertility preservation for male cancer patients a priority during pre-treatment planning.

  14. Male genital trauma

    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.

    Obesity is associated with significant disturbance in the hormonal milieu that can affect the reproductive system. Male infertility affects approximately 6% of reproductive-aged men. It has been suggested that overweight men or men with obese body mass index (BMI) experience prolonged time to pregnancy, although the influence of male BMI on fertility remains understudied. We hypothesised that BMI is inversely correlated with fertility, manifested by reduced sperm concentration and varicocele. Males of mean age 32.74 ± 6.96 years with semen analyses and self-reported BMI were included (n = 98). Patient parameters analysed included age, BMI, pubertal timing, the development of varicocele, and leutinizing hormone, follicle-stimulating hormone and testosterone (n = 18). The mean age of the study population was 32.74 ± 6.96 years. The incidence of azospermia, oligozoospermia, normospermia and the development of varicocele did not vary across BMI categories. Male obesity is not associated with the incidence of sperm concentration and the development of varicocele. PMID:24720635

    The main factor influencing sex determination of an embryo is the sex-determining region Y (SRY), a master regulatory gene located on the Y chromosome. The presence of SRY causes the bipotential gonad to differentiate into a testis. However, some individuals carry a Y chromosome but are phenotypically female (46,XY females) or have a female karyotype but are phenotypically male (46,XX males). 46, XX male is rare (1:20 000 in newborn males), and SRY positivity is responsible for this condition in approximately 90% of these subjects. External genitalia of 46,XX SRY-positive males appear as normal male external genitalia, and such cases are diagnosed when they present with small testes and/or infertility after puberty. Herein, we report an adolescent who presented with low testicular volume and who was diagnosed as a 46,XX male. SRY positivity was demonstrated in the patient by fluorescence in situ hybridization method. Conflict of interest:None declared. PMID:24379036

    Although common reproductive problems, such as male infertility and testicular cancer, present in adult life, strong evidence exists that these reproductive disorders might have a fetal origin. The evidence is derived not only from large epidemiological studies that show birth-cohort effects with regard to testicular cancer, levels of testosterone and semen quality, but also from histopathological observations. Many infertile men have histological signs of testicular dysgenesis, including Sertoli-cell-only tubules, immature undifferentiated Sertoli cells, microliths and Leydig cell nodules. The most severe gonadal symptoms occur in patients with disorders of sexual development (DSDs) who have genetic mutations, in whom even sex reversal of individuals with a 46,XY DSD can occur. However, patients with severe DSDs might represent only a small proportion of DSD cases, with milder forms of testicular dysgenesis potentially induced by exposure to environmental and lifestyle factors. Interestingly, maternal smoking during pregnancy has a stronger effect on spermatogenesis than a man's own smoking. Other lifestyle factors such as alcohol consumption and obesity might also have a role. However, increasing indirect evidence exists that exposure to ubiquitous endocrine disrupting chemicals, present at measurable concentrations in individuals, might affect development of human fetal testis. If confirmed, health policies to prevent male reproductive problems should not only target adult men, but also pregnant women and their children. PMID:24935122

    The purpose of this study was to describe surgical techniques and results of upper blepharoplasty for dermatochalasis to optimize cosmetic outcome in males, compared with females. We conducted a retrospective, interventional study on 156 eyes (78 patients) that had been diagnosed with dermatochalasis and had undergone upper lid blepharoplasty at the Korea University Hospital between August 2008 and October 2008 by a single surgeon. Twenty-eight male patients and 50 female patients were enrolled. Patient age, sex, follow-up duration, complications, and treatment were analyzed. We evaluated intraoperative (1) lid crease height, (2) skin-muscle excision amount, and (3) whether or not fat was removed. In total, 78 patients (28 men and 50 women: 156 procedures) who underwent upper eyelid blepharoplasty for dermatochalasis were identified. The mean age was 59.6 years in male patients, and 62 years in female patients (P = 0.165). No significant difference was observed between mean lid crease height and the distance between eyebrow lower margin to lid crease in males and females. The amount of skin-muscle excision in the female group was significantly greater than that in males. The frequency of fat removal was significantly lower in males than in females. For a good cosmetic outcome, we recommend (1) lower lid crease, (2) less skin-muscle excision using a scalpel shape design, (3) lateral orbicularis oculi muscle preservation, and (4) minimizing fat removal to avoid feminization in older male upper blepharoplasty.

    The absence of an ear is a considerable aesthetic problem which affects the patient’s psychology and social behaviour. We are describing a case of 25-year-old male reporting to the Department of Prosthodontics, with a chief complaint of deficient left auricular tissue. This can be corrected surgically, prosthetically or through a combination of these approaches; but the choice of treatment depends on patient. The patient chose prosthetic rehabilitation over surgical procedures & retention becomes a critical issue in this approach. Out of many types of retentive methods, we selectively incorporated new materials and used the latest technology to ensure the highest quality prosthesis. Creative approach for each patient with a focus on their individual needs was considered as it gives more satisfaction to the patient. This article describes a new, simple and cost effective technique by embedding Bluetooth-headset device into the silicone elastomer of a mechanically-retained auricular prosthesis. PMID:25302281

    The purpose of this research is to analyze aspects of the sexuality of people with mental disorders, an issue that influenced nursing care in the mixed nursing wards of the Institute of Psychiatry at the Federal University of Rio de Janeiro between 1996-2002. A qualitative Historical Social Study methodology used written and oral texts that were analyzed drawing on Michel Foucault's ideas about sexuality. Results of the study indicate that a rupture occurred in the distribution model according to gender at the Psychiatric Hospitalization Unit. This, in turn, influenced nursing care. From this study, we conclude that accommodating patients in mixed wards better facilitates the psychosocial rehabilitation process and changes nursing teams' conceptions about the sexuality of people with mental disorders.

    Hepatic adenoma is an uncommon benign lesion of the liver that occurs more frequently in women in their third and fourth decades. The female/male ratio is up to 11:1. Hepatic adenomas may be single or multiple occasionally reaching sizes up to 20?cm. They are non-cancerous lesions, however they can become malignant. We present a 21-year-old male patient with no medical history who presented with abdominal pain, a palpable abdominal mass, abnormal liver function tests and a 14?kg weight loss in a 2-year period. A CT scan was performed with a 17?cm tumour compressing intrahepatic bile ducts. The patient underwent a right hepatectomy with no complications. Histopathological analysis of the tumour revealed a hepatic adenoma with central necrosis. The patient is asymptomatic at 1-year follow-up. PMID:24306431

    A proper balance between androgen and oestrogen is fundamental for normal male reproductive development and function in both animals and humans. This balance is governed by the cytochrome P450 aromatase, which is expressed also under spatio-temporal control. Oestrogen receptors ER? and/or ER?, together with the membrane-associated G-protein-coupled functional ER (GPER), mediate the effects of oestrogen in the testis. Oestrogen action in male reproduction is more complex than previously predicted. The androgen/oestrogen balance and its regulation in the masculinisation programming window (MPW) during foetal life is the most critical period for the development of the male reproductive system. If this balance is impaired during the MPW, the male reproductive system may be negatively affected. Recent data from genetically modified mice and human infertile patients have shown that oestrogens may promote the engulfment of live Leydig cells by macrophages leading to male infertility. We also discuss recent data on environmental oestrogen exposure in men and rodents, where a rodent-human distinction is crucial and analyse some aspects of male fertility potentially related to impaired oestrogen/androgen balance.

    Pheromones function not only as mate attractors, but they may also relay important information to prospective mates. It has been shown that vertebrates can distinguish, via olfactory mechanisms, major histocompatibility complex types in their prospective mates. However, whether pheromones can transmit information about immunocompetence is unknown. Here, we show that female mealworm beetles (Tenebrio molitor) prefer pheromones from males with better immunocompetence, indicated by a faster encapsulation rate against a novel antigen, and higher levels of phenoloxidase in haemolymph. Thus, the present study indicates that pheromones could transmit information about males' parasite resistance ability and may work as a reliable sexual ornament for female choice. PMID:12204128

    Background Necrotizing fasciitis (NF) is a rapidly progressive infection of fascia and subcutaneous tissue resulting in serious outcomes. We aimed to evaluate the clinical presentations, hospital course and outcomes of NF based on patient gender. Patients and methods All patients admitted with NF were enrolled in the study over a 13-year period in the main tertiary hospital in Qatar. Clinical presentations, co-morbidities, severity and outcomes were analyzed and compared in male and female patients. Results A total of 331 NF patients were identified with a mean age of 51 ± 15 years and male to female ratio of 3:1. However, Arab Qatari females were more frequently affected by NF in comparison to their male counterparts and south Asian females (p < 0.001), respectively. Female patients were older and had significantly higher incidence of abdominal and groin NF (p < 0.004). There were 13 cases with recurrent NF; 85% of them were males. Male NF patients had significantly higher rate of organ failure (p = 0.02), but there was no significant difference in the hospital length of stay as well as mortality in both genders. Overall, there were 85 (25.7%) deaths (23 females and 62 males). Conclusion Necrotizing fasciitis remains a life threatening entity. Although, NF is more common in males, Qatari females are more likely to develop NF than males. NF of abdominal wall and groin is significantly higher in females. Development of organ failure is more common in males with NF. NF remains a challenging clinical problem in Qatar with a mortality rate ranging from 25 to 27% for both genders. PMID:26568823

  11. Effects of psychological stress on male fertility.

    PubMed

    Nargund, Vinod H

    2015-07-01

    Psychological stress can be defined as any uncomfortable 'emotional experience' accompanied by predictable biochemical, physiological and behavioural changes or responses. Many clinical studies looking at the effects of psychological stress on male fertility have shown that stress is associated with reduced paternity and abnormal semen parameters. Enough scientific evidence exists to suggest that psychological stress could severely affect spermatogenesis, mainly as a result of varying testosterone secretion. The hypothalamic-pituitary-adrenal axis has a direct inhibitory action on the hypothalamic-pituitary-gonadal (HPG) axis and Leydig cells in the testes. The newly discovered hormone, gonadotropin-inhibitory hormone (GnIH), also has an inhibitory effect on the HPG axis. Inhibition of the HPG axis results in a fall in testosterone levels, which causes changes in Sertoli cells and the blood-testis barrier, leading to the arrest of spermatogenesis. Germ cells also become vulnerable to gonadotoxins and oxidation. However, the extent and severity of the effects of psychological stress on human testes is difficult to study and data mostly come from animal models. Despite this limitation, stress as a causative factor in male infertility cannot be ignored and patients should be made aware of its effects on testicular function and fertility and helped to manage them.

    2012-01-01

    Contests among individuals over mating opportunities are common across diverse taxa, yet physical conflict is relatively rare. Due to the potentially fatal consequences of physical fighting, most animals employ mechanisms of conflict resolution involving signalling and ritualistic assessment. Here we provide the first evidence of ubiquitous escalated fighting in grasshoppers. The chameleon grasshopper (Kosciuscola tristis) is an Australian alpine specialist, in which males engage in highly aggressive combat over ovipositing females. We describe discrete agonistic behaviours including mandible flaring, mounting, grappling, kicking and biting, and their use depending on the individual's role as challenger or defender. We show that male role predicts damage, with challengers being more heavily damaged than males defending females (defenders). Challengers also possess wider mandibles than defenders, but are similar in other metrics of body size. Our data suggest that fights escalate between males matched in body size and that mandibles are used as weapons in this species. This system represents an exciting opportunity for future research into the evolution of costly fighting behaviour in an otherwise placid group. PMID:23166725

    A fundamental question in animal communication is whether the information provided is honest or deceptive [1, 2]. This problem has received much attention, both in theoretical [1, 3] and experimental [4] work. Here we show that male Atlantic mollies (Poecilia mexicana), when observed during mate choice by another male, reduce their mating activity and no longer prefer mating with one of two females presented, which can be interpreted as an attempt to avoid unintended interception of information by the rival male. Most importantly, focal males directed their first sexual interaction (after they were presented with the rival male) toward the initially nonpreferred female, suggesting that males deceive other males about their mating preferences. Deception by the choosing male may be an adaptation to avoid sperm competition, because surrounding males may use public information and copy the focal male's mate choice. PMID:18674912

    PubMed Central

    2015-01-01

    In damselflies, sexual colour dimorphism is commonly explained as a consequence of selection on traits that increase male attractiveness to females. However, while many species in the damselfly family Coenagrionidae (Insecta: Odonata) are sexually dimorphic, the males do not engage in displays, and male competition for mates resembles a “scramble”. An alternative explanation for the sexual differences in coloration within these species is that sexual dimorphism has evolved as a sex-related warning signal, with males signalling their uprofitability as mates to other males, thereby avoiding harassment from conspecifics. We evaluated an underlying assumption of the theory that male-male harassment rate is influenced by colour by comparing harassment of males of the species Nehalennia irene that had been painted to make them appear: (i) similar to an unaltered male (blue), (ii) different from a male (orange) and (iii) more similar to a female (black). When caged together we found that blue-painted males experienced significantly lower harassment than black-painted males. When unpainted males were caged with each type of painted male we found that blue-painted males and the unpainted males housed in the same cages experienced lower rates of harassment than males housed in cages where some males were painted black, suggesting that a single, reliable signal of unprofitability may benefit the individuals that carry it. While our results do not in themselves demonstrate that sexual colour dimorphism originally evolved as an intra-specific warning signal, they do show that harassment is influenced by coloration, and that such selection could conceivably maintain male coloration as a warning signal.

  1. The dynamics of male-male competition in Cardiocondyla obscurior ants

    PubMed Central

    2012-01-01

    Background The outcome of male-male competition can be predicted from the relative fighting qualities of the opponents, which often depend on their age. In insects, freshly emerged and still sexually inactive males are morphologically indistinct from older, sexually active males. These young inactive males may thus be easy targets for older males if they cannot conceal themselves from their attacks. The ant Cardiocondyla obscurior is characterised by lethal fighting between wingless (“ergatoid”) males. Here, we analyse for how long young males are defenceless after eclosion, and how early adult males can detect the presence of rival males. Results We found that old ergatoid males consistently won fights against ergatoid males younger than two days. Old males did not differentiate between different types of unpigmented pupae several days before emergence, but had more frequent contact to ready-to-eclose pupae of female sexuals and winged males than of workers and ergatoid males. In rare cases, old ergatoid males displayed alleviated biting of pigmented ergatoid male pupae shortly before adult eclosion, as well as copulation attempts to dark pupae of female sexuals and winged males. Ergatoid male behaviour may be promoted by a closer similarity of the chemical profile of ready-to-eclose pupae to the profile of adults than that of young pupae several days prior to emergence. Conclusion Young ergatoid males of C. obscurior would benefit greatly by hiding their identity from older, resident males, as they are highly vulnerable during the first two days of their adult lives. In contrast to the winged males of the same species, which are able to prevent ergatoid male attacks by chemical female mimicry, young ergatoids do not seem to be able to produce a protective chemical profile. Conflicts in male-male competition between ergatoid males of different age thus seem to be resolved in favour of the older males. This might represent selection at the colony level rather than the individual level. PMID:22703760

    Howard, Sasha; Dunkel, Leo

    2016-01-01

    Male delayed puberty is common, affecting up to 3% of the population. Management of patients with pubertal delay is dependent on the underlying cause. The main differential diagnoses of delayed puberty in males include constitutional delay of growth and puberty (CDGP), idiopathic hypogonadotropic hypogonadism and hypergonadotropic hypogonadism. Treatment of isolated CDGP involves expectant observation or short courses of low-dose sex steroid supplementation. More complex and involved management is required in males with hypogonadism to achieve both development of secondary sexual characteristics and to maximise the potential for fertility. This review will cover the options for management involving androgen or gonadotropin therapy, with discussion of benefits, limitations and specific considerations of the different treatment options.

    2015-12-01

    Male germ cell tumors (GCTs) are curable cancers, yet 10-15 % of patients with metastatic disease fail cisplatin-based first-line treatments. While therapeutic options have increased for various other cancers, little progress has been made in the management of GCT in the last decades. A better understanding of the molecular alterations underlying the disease and identification of new therapeutic targets are needed. Several phase I/II studies with promising new agents are ongoing or have been completed, but most of those trials have been small and have not included translational research. Therefore, molecular profiles predictive for response or new agents have not been identified in male GCT so far. The purpose of this review is to highlight emerging targets and therapies with the potential to improve systemic treatment of metastatic male GCT and to develop strategies for future clinical trials.

  4. Male-male competition and large size mating advantage in European earwigs, Forficula auricularia.

    PubMed

    Forslund

    2000-04-01

    European earwigs are sexually dimorphic in forceps shape and length. Male forceps are thought to be weapons in male contests for access to females, but recent findings suggest that females choose males on the basis of their forceps length. I investigated sexual selection on forceps length and body size and the occurrence of male-male competition. When I controlled for forceps length experimentally and statistically, relatively heavy males had greater copulation success than relatively light males. When I controlled for body size, males with relatively longer forceps had no tendency for greater copulation success than males with shorter forceps. Relatively heavy males more often took over copulations from smaller males than vice versa. Male contests were important for the outcome of mate competition, as males commonly interrupted and took over copulations. My results therefore suggest that intrasexual selection is significant in competition for copulations in male earwigs, and acts on body size. This contrasts with previous findings, which have shown intersexual selection on forceps length to be important. However, both modes of sexual selection may be acting through a two-stage process, where male-male competition first determines which males have access to females, and then through female choice among available males. Morphological measurements supported the conclusion that forceps length and body size are male secondary sexual characters, as these characters had large variance and skewed distributions in males, but were normally distributed in females.

  5. Homosexual behaviour increases male attractiveness to females.

    Male homosexual behaviour-although found in most extant clades across the Animal Kingdom-remains a conundrum, as same-sex mating should decrease male reproductive fitness. In most species, however, males that engage in same-sex sexual behaviour also mate with females, and in theory, same-sex mating could even increase male reproductive fitness if males improve their chances of future heterosexual mating. Females regularly use social information to choose a mate; e.g. male attractiveness increases after a male has interacted sexually with a female (mate choice copying). Here, we demonstrate that males of the tropical freshwater fish Poecilia mexicana increase their attractiveness to females not only by opposite-sex, but likewise, through same-sex interactions. Hence, direct benefits for males of exhibiting homosexual behaviour may help explain its occurrence and persistence in species in which females rely on mate choice copying as one component of mate quality assessment.

    Genital lymphedema is a debilitating condition. Currently, therapeutic concepts include conservative and surgical measures of genital volume reduction, but no therapy standards exist. The aim of this study was to analyze our experience with the treatment of male genital lymphedema and to describe our integrated concept, which combines perioperative complex decongestive physiotherapy (CDP) with surgical reduction. We conducted a retrospective study of 51 male patients who were treated in our clinic between 1998 and 2013, acquiring data on etiology, performed therapy, and complication rates. Forty-three (84%) of our patients suffered from primary and eight (16%) from secondary lymphedema. Two patients (4%) exhibited isolated penile affection and 22 (43%) isolated scrotal affection, while the majority (27 or 53%) exhibited penoscrotal lymphedema. All patients underwent inpatient CDP preceding and following surgery. Surgical therapy involved debulking the scrotum in 25 patients (49%), isolated penile reduction in two (4%), and penoscrotal reduction in 24 (47%). Hydrocoelectomy was performed in 22 (43%) patients. Following resection of the diseased tissue, the defects were closed primarily using adjacent healthy skin. There was no need for local flaps or skin grafts. Three patients suffered from complications requiring revision surgery: hematoma in two patients (4%) and wound dehiscence in one (2%). We measured the change in quality of life that was achieved by these procedures using the Glasgow Benefit Inventory questionnaire. The patients reported improvement in general functioning and physical health, whereas the social support score was largely unaffected by the procedure. Our results show that genital lymphedema patients can be reliably treated by combining conservative and surgical therapy. Prior conservative reduction of the genitals facilitates surgery and allows consistent results at a low complication rate, whereas surgical reduction serves to enhance and stabilize the results of conservative treatment.

    Mammalian reproductive tract development is a tightly regulated process that can be disrupted following exposure to drugs, toxicants, endocrine disrupting chemicals or other compounds via alterations to gene and protein expression or epigenetic regulation. Indeed, the impacts of developmental exposure to certain toxicants may not be fully realized until puberty or adulthood when the reproductive tract becomes sexually mature and altered functionality is manifested. Exposures that occur later in life, once development is complete, can also disrupt the intricate hormonal and paracrine interactions responsible for adult functions, such as spermatogenesis. In this chapter, the biology and toxicology of the male reproductive tract is explored, proceeding through the various life stages including in utero development, puberty, adulthood and senescence. Special attention is given to the discussion of endocrine disrupting chemicals, chemical mixtures, low dose effects, transgenerational effects, and potential exposure-related causes of male reproductive tract cancers.

    Different types of reproductive dysfunction with exposure of males and females during different stages of the reproductive process were correlated. It is a well-established principle that teratogenic exposure of the pregnant female, and thus of the embryo, during the organogenesis period of development can lead to birth defects in the offspring. The outcome of this exposure paradigm, as well as the outcomes associated with exposure during other stages of the reproductive process that have received less experimental attention are discussed. Insult to the germ cells of the male during spermatogenesis and to the female during oogenesis can also lead to reproductive dysfunction. The type of adverse outcome, however, is quite different from that occurring with embryonic exposure during the organogenesis period. An overview of this area will be given with the intent of focusing on those types of reproductive dysfunction that are most relevant to environmental exposure of men and women.

    Male-mediated developmental toxicity has been of concern for many years. The public became aware of male-mediated developmental toxicity in the early 1990s when it was reported that men working at Sellafield might be causing leukemia in their children. Human and animal studies have contributed to our current understanding of male-mediated effects. Animal studies in the 1980s and 1990s suggested that genetic damage after radiation and chemical exposure might be transmitted to offspring. With the increasing understanding that there is histone retention and modification, protamine incorporation into the chromatin and DNA methylation in mature sperm and that spermatozoal RNA transcripts can play important roles in the epigenetic state of sperm, heritable studies began to be viewed differently. Recent reports using molecular approaches have demonstrated that DNA damage can be transmitted to babies from smoking fathers, and expanded simple tandem repeats minisatellite mutations were found in the germline of fathers who were exposed to radiation from the Chernobyl nuclear power plant disaster. In epidemiological studies, it is possible to clarify whether damage is transmitted to the sons after exposure of the fathers. Paternally transmitted damage to the offspring is now recognized as a complex issue with genetic as well as epigenetic components. PMID:24369136

    Infertility in humans is surprisingly common occurring in approximately 15% of the population wishing to start a family. Despite this, the molecular and genetic factors underlying the cause of infertility remain largely undiscovered. Nevertheless, more and more genetic factors associated with infertility are being identified. This review will focus on our current understanding of the chromosomal basis of male infertility specifically: chromosomal aneuploidy, structural and numerical karyotype abnormalities and Y chromosomal microdeletions. Chromosomal aneuploidy is the leading cause of pregnancy loss and developmental disabilities in humans. Aneuploidy is predominantly maternal in origin, but concerns have been raised regarding the safety of intracytoplasmic sperm injection as infertile men have significantly higher levels of sperm aneuploidy compared to their fertile counterparts. Males with numerical or structural karyotype abnormalities are also at an increased risk of producing aneuploid sperm. Our current understanding of how sperm aneuploidy translates to embryo aneuploidy will be reviewed, as well as the application of preimplantation genetic diagnosis (PGD) in such cases. Clinical recommendations where possible will be made, as well as discussion of the use of emerging array technology in PGD and its potential applications in male infertility. PMID:22120929

    Non-hereditary angioedema is a common disease with a prevalence between 5% and 19% and approximately half of the patients experience a swelling of the tongue. We report a case of a 49-year-old Caucasian man with a gross life-threatening angioedema of the tongue, whose attacks occurred every 4 weeks. The most frequent causes of angioedema were excluded. We detected DNA and RNA from Bartonella henselae in the blood and saliva of the patient and in the saliva of the patient's hunting dog. Treatment with azithromycin plus minocycline cleared the blood and saliva of RNA and DNA of Bartonella species, and the patient has been free from angioedema for 1 year. None of the therapy modalities used to treat the hereditary form or ACE or allergy-induced angioedema affect the detrimental course caused by Bartonella species. We therefore suggest that a molecular Bartonella test be included in the analysis of angioedema. PMID:24654245

    The incidence of ketosis-prone diabetes mellitus (KPDM) shows a higher prevalence in men. The clear male predominance of this syndrome and its underlying pathogenesis mechanisms are unclear. KPDM, once described as atypical diabetes mellitus, idiopathetic type 1 diabetes (type 1B diabetes) and flatbush diabetes, is an uncommon form of diabetes characterized by severe reversible insulin deficiency. KPDM was first described and mostly observed in males of African-American descent and recently in Asian populations, including Japanese and Chinese. Patients with KPDM often present acutely with diabetic ketoacidosis without any immunological autoantibody to islet antigens of classic type 1 diabetes but demonstrate clinical and metabolic features of type 2 diabetes. Accumulating data indicated that gender-related body fat distribution, hormonal and genetic factors are associated with the diabetic process and the human glucose homeostasis and metabolism. A controversial question is whether and to what degree those factors contribute to the phenomenon of male predominance in KPDM. The present review focuses on the role of gender hormones and other potential precipitating factors in explaining the male predominance in KPDM patients. PMID:26171144

    To establish the extent of varicocele as the cause of infertility in men and compare the various techniques of treatment. We searched PubMed and the Cochrane Library database using varicocele, male infertility, varicocelectomy as keywords. Varicocele seems to be a growing problem considered to be one of the most common causes of male infertility in recent times. Nevertheless, its role remains unclear. The best treatment option seems to be microscopic surgery – the most effective and linked to rare surgical complications. But the greatest clinical problem remains the selection of patients to treat – recently it is believed that varicocelectomy is a possibly advisable option in patients with clinical varicocele and seminal parameter impairment [1]. More high-quality, multicenter, long-term randomized controlled trials (RCT's) are required to verify the findings. PMID:26568883

    Introduction Male circumcision practice is an invasive procedure that is using worldwide. It makes challenges to haemostatic system and its possible haemorrhagic side effects are more serious in bleeding individuals than normal subjects. In most cases, it can be complete controlled using infusion of appropriate amount of coagulation factors before and post circumcision. Aim We aim to documentation type of coagulation therapy and post circumcision practice haemorrhagic presentation among 463 bleeder males of both common and rare bleeding disorders in north eastern part of country. Methods We retrospectively gathered information using evaluation medical records in 3 major hospitals during last 15 years and list of patients with bleeding disorders that obtained from haemophilia center. Also a call phone established for each bleeder person to complete data and updating of them. The survey took time from Sep 2009 – Mar 2011. The designed question form included data on doing circumcision or not, types of treatment before and post the procedure and occurrence of bleeding episodes after the surgery. Results Overall among 424 cases with various common and rare bleeding disorders who had circumcised, 239 cases (56.3%) had passed the procedure with bleeding experience (indication of undiagnosed cases who underwent circumcision or inadequacy of coagulation therapy), while 185 cases (43.7%) had passed it successfully and without noticeable bleeding experience. The types of coagulation therapy in each group have been cited. Conclusion The circumcision practice in unequipped medical center for bleeder ones may make challenges for them and medical services.

    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 heritable studies with 1,3-butadiene have been used in the parallelogram approach to determine a risk assessment for the germ cells in man.

    Sex has always been a taboo subject in Asian society. However, over the past few years, awareness in the field of men's sexual health has improved, and interest in sexual health research has recently increased. The epidemiology and prevalence of erectile dysfunction, hypogonadism and premature ejaculation in Asia are similar in the West. However, several issues are specific to Asian males, including culture and beliefs, awareness, compliance and the availability of traditional/complementary medicine. In Asia, sexual medicine is still in its infancy, and a concerted effort from the government, relevant societies, physicians and the media is required to propel sexual medicine to the forefront of health care.

    Male Xenopus laevis frogs produce underwater advertisement calls that attract gravid females and suppress calling by male competitors. Here we explore whether groups of males establish vocal ranks and whether auditory cues alone suffice for vocal suppression. Tests of male–male pairs within assigned groups reveal linear vocal dominance relations, in which each male has a defined rank. Both the duration over which males interact, as well as the number of competitive opportunities, affect linearity. Linear dominance across the group is stable for about 2 weeks; rank is dynamic. Males engage in physical interactions (clasping) while paired but clasping and vocal rank are not correlated. Playbacks of advertisement calls suppress calling and calls from high- and low-ranking males are equally effective. Thus, auditory cues alone suffice to suppress vocal behavior. Playback intensities equivalent to a nearby male advertising effectively suppress calling while low-intensity playbacks are either ineffective or stimulate vocal behavior. X. laevis advertisement calls are biphasic, composed of alternating fast and slow click trills. Approximately half the males tested are more vocally suppressed by all slow than by all fast trills; thus, these males can distinguish between the two phases. The fully aquatic family Pipidae diverged from terrestrial ancestors approximately 170 mya. Vocal suppression in the X. laevis mating system may represent the translation of an ancient anuran social strategy to underwater life. PMID:21442049

    2010-09-01

    Lusitanian toadfish males that provide parental care rely on acoustic signals (the boatwhistle) to attract females to their nest. We test the hypothesis that male quality, namely male size and condition that are relevant for parental success, is reflected in vocal activity and boatwhistle characteristics and thus advertised to females. We recorded 22 males over a week during the peak of the breeding season. Calling rate and calling effort (percentage of time spent calling) strongly reflected male condition (lipid content of somatic muscles) and to a smaller extent sonic muscle hypertrophy and larger gonads. Males in better condition (increased body lipid and relative higher liver mass) also contracted the sonic muscles at faster rate as shown by the shorter boatwhistle pulse periods. Amplitude modulation reflected the degree of sonic muscle hypertrophy. None of the measured male quality parameters were good predictors of boatwhistle duration and dominant frequency. Altogether this study strongly suggests that Lusitanian toadfish males advertise their quality to females primarily with boatwhistle calling rate and calling effort, which mainly reflect male condition. Because pulse period had low variability, consistent with the existence of a vocal central pattern generator, we suggest that males that sustain sonic muscles contraction at a very fast rate close to their physiological limit may be honestly advertising their quality (condition). Similarly, males that produce boatwhistles with higher amplitude modulation, a feature that seems dependent on sonic muscle hypertrophy, could be more attractive to females. PMID:20709928

    There is mounting evidence that burnout is a risk factor for cardiovascular disease (CVD). Stress-related dysregulation of the sympathetic and parasympathetic system and the hypothalamic pituitary adrenal (HPA) axis may explain the enhanced risk for CVD. To test this hypothesis, 55 patients (34 males and 21 females) with burnout on sickness absence and 40 healthy participants (16 males and 24 females) were exposed to a psychosocial stressor consisting of mental arithmetic and public speech. Physiological variables (i.e., blood pressure, heart rate, cardiac output, vascular resistance, cortisol, and alpha-amylase) were measured. Basal levels, reactivity, and recovery were compared between groups. In male patients, baseline systolic blood pressure was higher, whereas basal alpha-amylase and cortisol reactivity were lower than in healthy males. In female patients, a tendency for lower basal cortisol was found as compared to healthy females. Furthermore, reduced basal heart rate variability and a trend for elevated basal cardiac output were observed in both male and female patients. Burnout is characterised by dysregulation of the sympathetic and parasympathetic system and the HPA axis, which was more pronounced in males than in females. This study further supports burnout as being a risk factor for CVD through dysregulation of the sympathetic and parasympathetic system and the HPA axis. PMID:26557670

    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.

    2011-01-01

    Objective Our primary aim was to compare the outcomes of synthetic bone-anchored male slings (BAMS) and transobturator male slings (TOMS), to identify preoperative risk factors for failure, and to evaluate patient satisfaction with each procedure. Patients and methods Charts were reviewed retrospectively of patients who underwent synthetic BAMS or TOMS from 2000 to 2011. Data were categorised into groups based on outcomes of ‘dry’, ‘improved’ and ‘failure’. Success was defined as completely dry or an improvement by >50% in daily pad use. The data analysed included demographics, daily pad use before and after surgery, previous urethral insult, type of prostatectomy, and urodynamic study variables. Data were analysed using logistical regression, the t-test and chi-square analysis, where appropriate. Results Sixty-eight men were analysed (30 in each group; eight patients were excluded). Daily pad use for the TOMS group changed from 3.5 before to 1.5 after surgery (P = 0.001), whilst the BAMS group was unchanged from 3.9 to 3.5 (P = 0.747). The TOMS group had a success rate of 23/30 (77%) and a mean (SD) patient global impression of improvement score of 1.67 (0.90), whilst the BAMS group had a success rate of 11/30 (37%) and mean (SD) score of 2.64 (1.12). Urethral insult (P = 0.001) and preoperative pad use (P = 0.047) were significant predictors of failure. Conclusion TOMS gave better outcomes than BAMS in both performance and patient satisfaction. Patients with a greater severity of incontinence and evidence of urethral insult before surgery should be counselled about the likelihood of suboptimal outcomes with any type of sling placement.

    Phenotypically plastic mating behavior may allow males to modify their reproductive behavior to suit the prevailing social conditions, but we do not know if males only react to immediate social stimuli or change their inherent mate preferences according to their social history. Here we examine the effect of social experiences on the subsequent reproductive behavior of male guppies under standard conditions, allowing us to distinguish the effect of past and immediate social conditions. Males experienced experimental conditioning periods during which they interacted with three females, either of variable size or of similar size. Females arrived either simultaneously or consecutively. In subsequent standard assays, only males that had experienced females of variable size preferentially courted large females. Further, males exposed to sequential female arrival courted subsequent females more vigorously than males that had experienced simultaneous female arrival. In contrast, males did not alter their coercive mating attempts in relation to their recent social history. These results demonstrate that males use past experiences to modify their subsequent reproductive behavior rather than reacting only to immediate stimuli, and reveal the sophisticated ways in which males alter their reproductive tactics to suit the social environment and maximize fitness across changing selective landscapes.

    Ocular involvement sometimes occurs with systemic lupus erythematosus (SLE) but enophthalmos with SLE is rare. We report a case of enophthalmos with SLE. A 25-year-old male was admitted for two weeks of fever, sore throat, arthralgia, chest pain and right arm weakness with pain. We diagnosed him with SLE with malar rash, arthritis, pleural effusion, proteinuria, leukopenia, positive antinuclear antibody, anti-dsDNA, and lupus anticoagulant. The patient was prescribed high-dose prednisolone and hydroxychloroquine 400?mg. One week after discharge, he complained about a sensation of a sunken right eye. CT showed right enophthalmos, a post-inflammatory change and chronic inflammation. Proteinuria increased to 3.8?g/day after the patient stopped taking prednisolone. Cyclophosphamide therapy was administered for three months without improvement. We decided to restart prednisolone and change cyclophosphamide to mycophenolate mofetil. Proteinuria decreased but enophthalmos remains as of this reporting. PMID:26306741

    Endovascular repair has become the first line of treatment in most patients with blunt aortic injury. The most common mechanism is deceleration injury affecting the aortic isthmus distal to the origin of the left subclavian artery. Injuries of the distal thoracic aorta are uncommon. We report the case of a 25-year-old male patient who presented with paraplegia and distal thoracic aortic pseudoaneurysm associated with severe thoracolumbar vertebral fracture and displacement after a motocross accident. Endovascular repair was performed using total percutaneous technique and conformable C-TAG thoracic stent-graft (WL Gore, Flagstaff, AZ). Following stent-graft placement and angiographic confirmation of absence of endoleak, thoracolumbar spinal fixation was performed in the same operative procedure. This case illustrates a multispecialty approach to complex aortic and vertebral injury and the high conformability of newer thoracic stent-grafts to adapt to tortuous anatomy. PMID:25406266

    The role of antisperm antibodies (ASA) in the aetiopathogenesis of varicocoele-related male infertility remains unclear. The objective of this study was to determine whether varicocoele is associated with antisperm immune response and whether this factor provides additional affect on male fertility. We performed a multicentral, prospective study that included the clinical examination of 1639 male subjects from infertile couples and 90 fertile men, the evaluation of the absolute and relative risks of immune infertility associated with varicocoele and the impact of the autoimmune response on the semen quality. The methods used were as follows: standard examination of seminal fluid according to WHO criteria; ASA detection in seminal fluid using mixed antiglobulin reaction (MAR) and direct flow cytometry; measurement of spontaneous and ionophore-induced acrosome reactions; oxidative stress evaluation with luminal-dependent chemiluminescence method and evaluation of DNA fragmentation by sperm chromatin dispersion. The prevalence of varicocoele-related immune infertility is about 15% and does not depend on the grade of vein dilatation both in primary and secondary fertility disorders. Varicocoele is not an immediate cause of autoimmune reactions against spermatozoa, but is a cofactor increasing ASA risk; the OR of immune infertility after a testicular trauma in varicocoele patients increases twofold. In varicocoele patients, the autoimmune antisperm reaction is accompanied by a more significant decrease in the semen quality (concentration and number of progressively motile and morphologically normal spermatozoa in the ejaculate), acrosome reaction disorders (presence of pre-term spontaneous and lack of induced reactions) and an increase in the proportion of spermatozoa with DNA fragmentation. These disorders correlate with the level of sperm oxidative stress; reactive oxygen species (ROS) production in ASA-positive varicocoele patients is 2.8 and 3.5 times higher than in ASA-negative varicocoele patients and fertile men respectively. We did not find correlation between the grade of spermatic cord vein dilatation and ROS production. PMID:24285668

    Background: Congenital bilateral absence of the vas deferens (CBAVD) is presumed to occur prenatally and is present in over 99% of adult males with cystic fibrosis (CF). Aims: To describe ultrasonic features in male children with CF. We aimed to describe urogenital anomalies, comparing pancreatic sufficient and insufficient CF patients. Methods: Pelvic and scrotal ultrasonography were performed in 12 boys with CF aged 2–12 years and 16 age matched healthy controls. Results: Nine patients had pancreatic insufficiency (PI): seven had two severe mutations and two had unknown mutations. Three boys were pancreatic sufficient (PS), two with splicing mutations (5T and 3849+10kb C–T respectively) and borderline sweat tests. Seminal vesicles were visualised in 5/12 patients and 8/16 controls, compared to non-visualisation reported in all adults with CBAVD. Testicular microlithiasis was found in 4/18 PI, 0/6 PS, and 0/32 control testes, compared to 0.6–1.4% in healthy males and 15% in CF adults; 7/18 PI, 4/6 PS, and 0/32 control testes were smaller than predicted for age. The epididymal head was non-homogeneous with cysts, hypo-, or hyper-echogenicity in 5/18 PI, 1/6 PS, and 0/32 control testes. Conclusions: Genital abnormalities may occur early in CF, but are less common than described in adults. They are found more often in pancreatic insufficient than in pancreatic sufficient CF patients. However, a positive finding, if present, may aid in the diagnosis of the latter. A larger longitudinal study is recommended to better define the onset and progression of urogenital abnormalities.

    Social interaction with conspecifics can influence the developing brain and behaviour of the exposed animal. This experience can involve the exchange and retention of visual, chemical, acoustic and tactile signals. When several Drosophila melanogaster male flies are associated with mated females in the presence of food, they show frequent aggressive interactions. To measure the role of social experience on male-male interaction, two tester males - naive or exposed to sibling(s) during a variable period of their adult development - were confronted in the absence of female and food. The two males displayed homosexual courtship and aggressive behaviours, the frequency, intensity and directionality of which varied according to their experience. The effect of social experience was greatly enhanced between transgenic males partially defective for pheromonal perception, indicating that male inhibitory pheromones are normally used to repress male-male interaction.

    The Anopheles gambiae species complex comprises the primary vectors of malaria in much of sub-Saharan Africa. Most of the mating in these species occurs in swarms composed almost entirely of males. Intermittent, organized patterns in such swarms have been observed, but a detailed description of male-male interactions has not previously been available. We identify frequent, time-varying interactions characterized by periods of parallel flight in data from 8 swarms of Anopheles gambiae and 3 swarms of Anopheles coluzzii filmed in 2010 and 2011 in the village of Donéguébogou, Mali. We use the cross correlation of flight direction to quantify these interactions and to induce interaction graphs, which show that males form synchronized subgroups whose size and membership change rapidly. A swarming model with damped springs between each male and the swarm centroid shows good agreement with the correlation data, provided that local interactions represented by damping of relative velocity between males are included.

    Sexually selected male weaponry is widespread in nature. Despite being model systems for the study of male aggression in Western science and for cricket fights in Chinese culture, field crickets (Orthoptera, Gryllidae, Gryllinae) are not known to possess sexually dimorphic weaponry. In a wild population of the fall field cricket, Gryllus pennsylvanicus, we report sexual dimorphism in head size as well as the size of mouthparts, both of which are used when aggressive contests between males escalate to physical combat. Male G. pennsylvanicus have larger heads, maxillae and mandibles than females when controlling for pronotum length. We conducted two experiments to test the hypothesis that relatively larger weaponry conveys an advantage to males in aggressive contests. Pairs of males were selected for differences in head size and consequently were different in the size of maxillae and mandibles. In the first experiment, males were closely matched for body size (pronotum length), and in the second, they were matched for body mass. Males with proportionately larger weaponry won more fights and increasing differences in weaponry size between males increased the fighting success of the male with the larger weaponry. This was particularly true when contests escalated to grappling, the most intense level of aggression. However, neither contest duration nor intensity was related to weaponry size as predicted by models of contest settlement. These results are the first evidence that the size of the head capsule and mouthparts are under positive selection via male-male competition in field crickets, and validate 800-year-old Chinese traditional knowledge.

    Male factor is a common cause of infertility and the male partner must be systematically evaluated in the workup of every infertile couple. Various Eastern medical strategies have been tried with variable success. This article describes the clinical effects of Eastern medicine approaches including acupuncture, Chinese herbal medicine, massage, yoga, tai chi, and qi gong, which could improve the sperm parameters and motility, genital inflammatory conditions, as well as immune system disorders, sexual dysfunction, and varicocele. Acupuncture reduces inflammation, increases sperm motility, improves semen parameters, modulates the immune system, and improves sexual and ejaculatory dysfunction in male infertility. The clinical effects may be mediated via activation of somatic afferent nerves innervating the skin and muscle. Chinese herbal medicines may also exert helpful effects in male infertility, and it is worth noting that some herbal drugs may result in male infertility. Massage also exerts positive effects in male infertility. Nevertheless, the mechanisms of clinical effects are unclear. Tai chi, qi gong, and yoga have not been investigated in male infertility, but it has been reported to regulate endocrine and central or autonomic nervous systems. In conclusion, Eastern medical approaches have beneficial on reproductive effects in male infertility. However, future well-designed, randomized, clinical control trials are needed to evaluate the safety, efficacy, and mechanisms of Eastern medical approaches for male infertility. PMID:23775386

    Sexually selected signals are common in many animals, though little reported in social insects. We investigated the occurrence of male visual signals mediating the dominance relationships among males and female choice of sexual partner in the paper wasp Polistes simillimus. Males have three conspicuous, variable and sexually dimorphic traits: black pigmentation on the head, a pair of yellow abdominal spots and body size differences. By conducting behavioral assays, we found that none of the three visual traits are associated with male-male dominance relationship. However, males with higher proportion of black facial pigmentation and bigger yellow abdominal spots are more likely chosen as sexual partners. Also, after experimentally manipulating the proportion of black pigment on males' face, we found that females may evaluate male facial coloration during the choice of a sexual partner. Thus, the black pigmentation on P. simillimus male's head appears to play a role as a sexually selected visual signal. We suggest that sexual selection is a common force in Polistes and we highlight the importance of this group as a model for the study of visual communication in insects. PMID:24849073

    The authors report on a series of 254 consecutive male patients who underwent transrectal US, sometimes combined with uroflowmetry, for the study of micturitonal phase. 170 patients were studied with both techniques. In 118 patients, there was complete agreement between the two methods about presence and degree of flow obstruction; partial disagreement was observed in 48 patients and complete disagreement in 4. On 44/52 patients with partial/complete disagreement diagnostic cystouretrography was performed. Our results demonstrate high agreement between the two techniques, except in case of micturition deficit with columnar hypertrophic bladder and in obstructive pathologic conditions of anterior urethra.

    Roper, W G

    1996-02-01

    This hypothesis agrees with Le Vay's suggestion that the two phenomena of childhood behavior and adult sexuality are induced by separate events rather than being two events in a single chain. However, it differs from Le Vay in that it includes the postnatal period, as being of crucial importance in the development of adult sexuality. Male homosexuality is portrayed as a biological variation of human sexuality and the hormonal changes which may produce it are described. It is postulated that sexual preference is dictated by testosterone action on the brain possibly commencing prenatally but certainly continuing during a critical postnatal period. It is proposed that reduction in testosterone action results in reduced proliferation of hypothalamic nuclei, which play a vital role in psycho-sexual orientation. The cause of this reduction in testosterone is the prolongation of hyperprolactinemia during this critical postnatal period, which is deemed to be secondary to prolactin microadenomata stimulated to secrete prolactin by high estrogen levels at the end of pregnancy and failing to turn off this secretion until after this critical postnatal period. It is postulated that there is a temporal dissociation between the development of masculine behaviour and psycho-sexual orientation, but that hormonal influences may overlap these periods. Hyperprolactinemia, caused by stress upon the infant, may also influence psycho-sexual orientation. PMID:8692050

    In contrast to women, men do not experience a sudden cessation of gonadal function comparable to menopause. However, there is a progressive reduction in male hypothalamic-pituitary-gonadal (HPG) axis function: testosterone levels decline through both central (pituitary) and peripheral (testicular) mechanisms, and there is a loss of the circadian rhythm of testosterone secretion. The progressive decline in testosterone levels has been demonstrated in both cross-sectional and longitudinal studies, and overall at least 25% of men over age 70 meet laboratory criteria for hypogonadism (ie, testosterone deficiency). Such age-associated HPG hypofunctioning, which has been termed "andropause," is thought to be responsible for a variety of symptoms experienced by elderly men, including weakness, fatigue, reduced muscle and bone mass, impaired hematopoiesis, sexual dysfunction (including erectile dysfunction and loss of libido), and depression. Although, it has been difficult to establish correlations between these symptoms and plasma testosterone levels, there is some evidence that testosterone replacement leads to symptom relief, particularly with respect to muscle strength, bone mineral density, and erectile dysfunction. There is little evidence of a link between the HPG axis hypofunctioning and depressive illness, and exogenous androgens have not been consistently shown to have antidepressant activity. This article reviews the relationship between androgens, depression, and sexual function in aging men. PMID:18227789

    Duchenne and Becker muscular dystrophy are allelic X-linked disorders causing progressive muscle weakness in males. Duchenne muscular dystrophy is caused by absence of dystrophin in muscle and brain; boys with Duchenne muscular dystrophy have a static cognitive impairment with mean Full Scale IQ approximately 1 standard deviation below the mean. Less is known of the cognitive profile of males with Becker muscular dystrophy, which is associated with variable alterations in the amount or size of the dystrophin protein. The aim of this study was to describe the cognitive and psychological profile of males with Becker muscular dystrophy. This was a prospective cohort study. Clinical data collected included age at diagnosis and assessment, socioeconomic status, serum creatine kinase level, and site of gene deletion/mutation (by exon number). The following psychological tests were used to assess general intellectual functioning, academic achievement, incidence and nature of behavioral problems: The Wechsler Intelligence Scales, The Wide Range Achievement Test-Revised, The Developmental Test of Visual-Motor Integration, The Child Behavior Checklist, and The Conner's Parent Rating Scale. Twenty-four males were enrolled. The Wechsler Full Scale IQ was normally distributed with a mean of 95.6 (SD 23.3), which did not differ significantly from the population mean. The frequency of learning difficulties for reading was 21%, for spelling was 32%, and for arithmetic was 26%, significantly higher than the frequency in the general population. The frequency of total behavioral problems in the clinical range was 67%, and the frequency of autism was 8.3%. Patients with Becker muscular dystrophy demonstrate a less homogeneous cognitive phenotype than that seen in Duchenne muscular dystrophy. Males with Becker muscular dystrophy have a high incidence of learning difficulties. Autism and behavioral and attention problems are also more common in Becker muscular dystrophy than in the general population. PMID:18056690

  12. Both male and female identity influence variation in male signalling effort

    PubMed Central

    2011-01-01

    Background Male sexual displays play an important role in sexual selection by affecting reproductive success. However, for such displays to be useful for female mate choice, courtship should vary more among than within individual males. In this regard, a potentially important source of within male variation is adjustment of male courtship effort in response to female traits. Accordingly, we set out to dissect sources of variation in male courtship effort in a fish, the desert goby (Chlamydogobius eremius). We did so by designing an experiment that allowed simultaneous estimation of within and between male variation in courtship, while also assessing the importance of the males and females as sources of courtship variation. Results Although males adjusted their courtship depending on the identity of the female (a potentially important source of within-male variation), among-male differences were considerably greater. In addition, male courtship effort towards a pair of females was highly repeatable over a short time frame. Conclusion Despite the plasticity in male courtship effort, courtship displays had the potential to reliably convey information about the male to mate-searching females. Our experiment therefore underscores the importance of addressing the different sources contributing to variation in the expression of sexually-selected traits. PMID:21827657

    Background Given recent assertions suggesting that gender role endorsement may be relevant in the divergence of male body image concerns, this study examined the self-reported gender role endorsement in opposing dimensional extremes of male body image disorders, namely, muscle dysmorphia and anorexia nervosa. This study further examined the relationship between gender role endorsement and eating disordered and muscle dysmorphia disorder pathology. Methodology Participants were 21 male muscle dysmorphia patients, 24 male anorexia nervosa patients, and 30 male gym-using controls from Australia, the United Kingdom, and the United States. All participants completed multidimensional measures of masculinity and femininity, and measures of eating disorder and muscle dysmorphia symptomatology. Results Patients with muscle dysmorphia reported significantly elevated adherence to masculine (but not feminine) norms relative to control gym-using men and men with anorexia nervosa, whereas patients with anorexia nervosa exhibited elevated feminine (but not masculine) gender role endorsement relative to control gym-using men and men with muscle dysmorphia. Conclusions Masculine and feminine gender role endorsement appear to be associated with the divergence of body image concerns towards muscularity and thinness-oriented ideals respectively.

    Different modes of fatigue onset in male Gulf War veterans versus male civilians raise the possibility that chronic fatigue syndrome (CFS) may not be a single disease entity. We addressed this issue by comparing 45 male veterans with CFS to 84 male civilians who satisfied identical case criteria. All were evaluated for fibromyalgia (FM), multiple chemical sensitivity and psychiatric comorbidity. CFS was more likely to present in a sudden flu-like manner in civilians than veterans (p < .01) and comorbid FM was more prevalent in civilians (p < .01). These findings question the assumption that all patients with CFS suffer from the same underlying disorder. PMID:18420761

    This paper provides a critical review of the literature relating to male sex work and outlines approaches to theorizing about and researching male sex work. The adequacy of these models to explain the male sex work industry is discussed. The literature reveals that earlier studies conceptualized male sex work as deviance and focused on the individual sex worker and his reasons for engaging in sex work. Although the research agenda has recently moved away from the individual sex worker towards the sex work industry, the focus of the investigation continues to be from a deviance rather than a work perspective. A number of aspects of male sex work have received little attention in the literature. These include the interpersonal dialogues and power relations that constitute the commercial sexual negotiation, the role of political and economic forces, and expressions of male sexuality within the practice of commercial sex. The paper suggests future research directions and argues that researchers need to draw on the strengths of the male sex work community in order to promote safe sex practices in commercial researchers need to draw on the strengths of the male sex work community in order to promote safe sex practices in commercial sexual settings.

  14. Flirtation reduces males' fecundity but not longevity.

    PubMed

    2015-08-01

    Theory predicts that due to limited resources males should strategically adjust their investment in reproduction and survival. Based on different conceptual framework, experimental designs, and study species, many studies support while others contradict this general prediction. Using a moth Ephestia kuehniella whose adults do not feed and thus have fixed resources for their lifetime fitness, we investigated whether males adjusted their investment in various life activities under dynamic socio-sexual environment. We allowed focal males to perceive rivals or additional females without physical contact. We show that males do not adjust the number of sperm they transfer to mates in a given copulation at different immediate or both immediate and mean sperm competition levels. Contradictory to general predictions, our results demonstrate that cues from additional females increase males' investment in courtship and reduce their lifetime number of copulations and sperm ejaculated, whereas cues from rivals have no effect on these parameters. Males have similar longevity in all treatments. We suggest that the sex pheromone produced by multiple females overstimulate males, increasing males' costly flirtations, and reducing their lifetime copulation frequency and fecundity. This finding offers a novel explanation for the success of mating disruption strategy using sex pheromones in pest management. PMID:26133013

  15. [Consideration of the concepts of "remission" and "cured" in schizophrenia: a male case who experienced schizophrenia with psycho-motoric excitation 30 years ago].

    Since the era of Kraepelin and Bleuler, schizophrenia has been considered to be very difficult to cure. Even if all symptoms of its acute phase have disappeared completely, it is customary to use the terms say "remission" instead of "cured". The chief reason why they have been unwilling to say "cured" is that, even if the present state seems to be "cured", there will be surely another attack in near future, so, the non-symptomatic state should not be understood as "cured". Whether schizophrenic patients can be cured or not is one of the great problems of modern psychiatry. Is there no probability for them to be cured? Recently, after a 30 years gap, I came to meet a man who had had a schizophrenic attack of the psychomotoric type when he was 25 years old and had been sent to the mental hospital where I had been at work and, by chance, had engaged in his treatment. After about 5 months' of acute state, he came at, so to speak, "Residualzustand" (Conrad) for about 1 year and then got insight into his psychosis. After the discharge, he had visited me as an outpatient once a month regularly. About one year thereafter, the change of my work place made us separate from each other. Since then, he stopped visiting the doctor and also stopped taking anti-psychotic drugs. He married at 29 years old and had 2 daughters and a son. In addition, he had started to work for his father's business. After his father's death, he became the owner of 5 shops and the supervisor of 50 workers. Is he not yet "cured"? Is he only in the state of "remission" even now? According to the principle of Kraepelin and Bleuler, he is not "cured" yet, because he will surely have a psychotic exacerbation in future. I wonder then, what is the difference of the two concepts of "remission" and "cured", and how is it possible to change "remission" to "cured"? Even Bleuler, E. has written in his world-famous textbook that the longer the duration of remission after the last attack, the smaller the probability of the next attack, and that after about 5 years free of attack, another exacerbation would be very improbable. Supported by the experiences of Utena, Miya and so forth, I proposed a thesis that if a person who had undergone schizophrenic attack has been in complete remission for more than 10 years, he can surely be counted as "cured". To verify this probability about the outcome of schizophrenia, it is very important for us to observe any patient who has attained the state of complete remission, and to describe and report his state thereafter as long enough as PMID:16408424

  16. Estimation of Male Gene Flow: Use Caution.

    PubMed

    Hedrick, Philip W; Singh, Sujeet; Aspi, Jouni

    2015-01-01

    Because male gene flow cannot easily be estimated directly in many organisms, Hedrick et al. (2013) provided an approach to estimate male gene flow given estimates of diploid nuclear and female differentiation. This approach appears to work well when there is lower female than male gene flow. However, in a tiger data set there was less female differentiation observed as estimated by mitochondrial DNA than expected given the observed overall nuclear diploid differentiation. To analyze these data, we suggest an alternative approach which allows incorporation of sex-specific gene flow and sex-specific effective population size. We find that the pattern of differentiation observed in tigers was consistent with a lower male than female effective population size using this alternative approach. Further, this finding is consistent with observed data in tigers where the male effective population size was 33% that of the female effective population size. PMID:26464090

    The use of non-ejaculated sperm coupled with intracytoplasmic sperm injection has become a globally established procedure for couples with azoospermic male partners who wish to have biological offspring. Surgical methods have been developed to retrieve spermatozoa from the epididymides and the testes of such patients. This article reviews the methods currently available for sperm acquisition in azoospermia, with a particular focus on the perioperative, anesthetic and technical aspects of these procedures. A critical analysis of the advantages and disadvantages of these sperm retrieval methods is provided, including the authors' methods of choice and anesthesia preferences. PMID:23503959

    Bart, Jonathan; Earnst, Susan L.

    1999-01-01

    We studied pairing success in male rock ptarmigan (Lagopus mutus) in northern Alaska to learn whether males obtaining more females possessed phenotypic traits that influenced female choice directly, whether these traits permitted males to obtain territories favored by females, or whether both processes occurred. The number of females per male varied from zero to three. Several male and territory traits were significantly correlated with number of females per male. We used multiple regression to obtain a single measure of male quality and a single measure of territory quality. These measures of male and territory quality correlated with each other and with male pairing success. We used path analysis to separate direct effects of male quality on pairing success from indirect effects due to high-quality males obtaining high-quality territories. Both direct and indirect pathways had significant effects on pairing success, and direct and indirect effects of male traits on pairing success were about equal. This study illustrates an analytical approach for estimating the relative importance of direct and indirect causal relationships in natural systems.

  2. The decline in Australian young male suicide.

    Morrell, Stephen; Page, Andrew N; Taylor, Richard J

    2007-02-01

    Since the late 1990s there has been a sharp downward trend in Australian young male suicide. It is possible that a major government youth suicide prevention initiative, the National Youth Suicide Prevention Strategy (NYSPS), implemented during 1995-1999 may have influenced the decline. In this article, we examine time trends in age- and means-specific male and female Australian suicide rates in relation to unemployment rates and the NYSPS. Based on Australian suicide data over the period 1966-2003, we assess secular changes in the 20-24 year male suicide to total (crude) male suicide rate ratio in relation to the NYSPS, using interrupted time series analysis (ARIMA), since this was previously found to be significantly associated with the 20-24 year male unemployment to total employment ratio. Results show that a dramatic reduction in Australian young male (aged 20-34 years) suicide has occurred since 1997-1998, declining from approximately 40 per 100,000 in 1997-1998 to approximately 20 per 100,000 in 2003. Most of the decline is due to a decrease in suicide by hanging and to a lesser extent from motor vehicle carbon monoxide and other gases. Further, the previously established strong secular association (lasting over 3 decades from 1966) between the rate ratio of 20-24 year male suicide to total (crude) male suicide, and the rate ratio of 20-24 year male unemployment to total unemployment, appears to have been disrupted. ARIMA modelling of the suicide ratio against the initiative indicates a highly significant statistical association between the NYSPS and the suicide ratio reduction but not between the NYSPS and the unemployment indicator trend, suggesting a break in the link between young male suicide and unemployment. The recent sudden turnaround in Australian young male suicide trends and its extent appears to preclude explanations centring on slow-moving social indices traditionally associated with suicide, or on possible cohort effects. This sudden decrease has occurred mainly in non-impulsive means, and at the same time has broken a long-standing secular link between 20 and 24-year-male suicide and unemployment, lending plausibility to the case for the NYSPS having had an impact on young male suicide in Australia.

    Posterior sternoclavicular joint dislocation (PSCJD) is quite a rare condition. Nearly half of the closed reduction attempts fail due to various reasons. In this paper, we present a 25-year-old male patient who was admitted to the emergency department in our hospital after having a motor-vehicle accident. It was decided to do PSCJD after physical and imaging studies. Following necessary preparations, closed reduction was attempted with abduction-traction maneuver under general anesthesia; however, adequate stabilization could not be achieved and redislocation was detected during control. Therefore, joint was stabilized with tension band technique using 6?mm polyamide nonabsorbable type suture during open reduction. Painless and complete range of motion in shoulder was achieved at the postoperative 10th week. PMID:26613059

    Two unusual cases of intravascular fasciitis arising in a 25-year-old female and a 26-year-old male are presented here. The lesions apparently presented as firm, raised, submucosal nodules on the tongue. Intravascular fasciitis (IVF) shares the microscopic features of nodular fasciitis (NF), but with intraluminal, intramural, and extramural involvement of small- to medium-sized veins and arteries with a multinodular or serpentine growth pattern along the course of affected blood vessels. NF is a benign lesion occurring on the trunk and upper extremities with a strong predilection for young adults 20 to 40 years of age. Intraoral NF is uncommon, and intraoral IVF is extremely rare, with only sporadic reports in the literature. In both of our cases, the patient's main concern was rapid growth of the lesion, which was nontender, on the tongue. The clinical, histologic, and immunohistochemical features and treatment are presented, along with a review of the literature. PMID:26163438

    Acquired external auditory canal atresia is a rare complication of chronic inflammatory otitis, and is generally fibrous or soft tissue in nature. Here, we present the first reported case of heterotopic ossification within chronic fibrosing otitis externa in a 25-year-old male patient with a childhood history of granular myringitis and failed tympanoplasty. A calcified mass was demonstrated adjacent to the tympanic membrane on CT imaging, and surgical exploration revealed a cohesive bar of bone traversing the medial external auditory canal. Drill canaloplasty and split-thickness skin graft coverage of the lateral tympanic membrane resulted in an improvement in the pure tone average from 79 to 55 dB. As the treatment for chronic fibrosing otitis externa involves the surgical widening of the external auditory canal, we alert surgeons to the possibility of cohesive bone formation as a potential cause of navigational confusion and inadvertent over- or under-drilling of the canal stenosis.

    Prostatic utricle cysts with calculus and hypospadias are rare. There are a few reported cases. We present a case of a prostatic utricle cyst with huge calculus in a 25-year-old male. He had a history of left cryptorchidism and surgery for penoscrotal hypospadias in his infancy. He was referred for frequent micturition, urgency of urination, urine pain, terminal hematuria, and dysuria. A computed tomography (CT) revealed a retrovesical cystic lesion of low density, showing a 5 × 5-cm calcification. Retrograde urethrocystography showed a 5 × 5-cm high-density shadow in the posterior urethra. The cyst was incised by transperineal approach and the stone was clearly observed and removed. Urethral stricture repair was performed simultaneously. The patient recovered smoothly after surgery. PMID:26029314

    Orofacial granulomatosis is an uncommon disease, usually presenting as recurrent or persistent swelling of the soft tissues, predominantly lips - termed as Cheilitis Granulomatosa. Though various aetiological factors like foreign body reactions, infections, Crohn’s disease and Sarcoidosis have been implicated in the disease process. Delayed Hypersensitivity reaction with a predominant Th1-mediated immune response provide further evidence to the etiopathogenesis in Orofacial granulomatosis. The term Idiopathic Orofacial Granulomatosis is used in cases with unknown aetiology. This case report describes Idiopathic Orofacial granulomatosis in a 25-year-old male patient with persistent upper lip swelling and gingival enlargement. Management with intralesional triamcinolone acetonide 40mg, twice a week for three weeks, resulted in significant remission without recurrence after a eight month follow up. PMID:25584331

    Desmoplastic small-round-cell tumor (DSRCT) is an uncommon type of malignancy, which primarily occurs in adolescent males and develops in the abdominal cavity. The present study reports the case of two manifestations of DSRCT complicated with other diseases, which involved the invasion of the pelvis or abdominal vessels. The first case was of a 25-year-old man with repeated diarrhea and abdominal distension for 9 months; the second case was of a 68-year-old man who presented with persistent abdominal pain for 20 days. In each patient, a mass was identified in the abdomen and biopsies were performed in order to reach a diagnosis. Immunohistochemical staining of the biopsy material revealed a diagnosis of DSRCT in each case. In addition, the present study aimed to discuss the use of imaging techniques in providing evidence for the early diagnosis of DSRCT.

    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. PMID:25215634

  14. Primate Socioecology: New Insights from Males

    NASA Astrophysics Data System (ADS)

    Kappeler, Peter M.

    Primate males have only recently returned to the center stage of socioecological research. This review surveys new studies that examine variation in the behavior of adult males and their role in social evolution. It is shown that group size, composition, and social behavior are determined not only by resource distribution, predation risk, and other ecological factors, but that life history traits and social factors, especially those related to sexual coercion, can have equally profound consequences for social systems. This general point is illustrated by examining male behavior at three levels: the evolution of permanent associations between males and females, the causes and consequences of variation in the number of males between group-living species, and the determinants of social relationships within and between the sexes. Direct and indirect evidence reviewed in connection with all three questions indicates that the risk of infanticide has been a pervasive force in primate social evolution. Several areas are identified for future research on male life histories that should contribute to a better understanding of male reproductive strategies and corresponding female counterstrategies.

  15. Variations in Antioxidant Genes and Male Infertility

    PubMed Central

    Yu, Bolan; Huang, Zhaofeng

    2015-01-01

    Oxidative stress and reactive oxygen species (ROS) are generated from both endogenous and environmental resources, which in turn may cause defective spermatogenesis and male infertility. Antioxidant genes, which include catalase (CAT), glutathione peroxidase (GPX), glutathione S-transferase (GST), nitric oxide synthase (NOS), nuclear factor erythroid 2-related factor 2 (NRF2), and superoxide dismutase (SOD), play important roles in spermatogenesis and normal sperm function. In this review, we discuss the association between variations in major antioxidant genes and male infertility. Numerous studies have suggested that genetic disruption or functional polymorphisms in these antioxidant genes are associated with a higher risk for male infertility, which include low sperm quality, oligoasthenoteratozoospermia, oligozoospermia, and subfertility. The synergistic effects of environmental ROS and functional polymorphisms on antioxidant genes that result in male infertility have also been reported. Therefore, variants in antioxidant genes, which independently or synergistically occur with environmental ROS, affect spermatogenesis and contribute to the occurrence of male infertility. Large cohort and multiple center-based population studies to identify new antioxidant genetic variants that increase susceptibility to male infertility as well as validate its potential as genetic markers for diagnosis and risk assessment for male infertility for precise clinical approaches are warranted.

    PubMed

    Young, Brent; Conti, David V; Dean, Matthew D

    2013-12-01

    In a variety of taxa, males deploy alternative reproductive tactics to secure fertilizations. In many species, small "sneaker" males attempt to steal fertilizations while avoiding encounters with larger, more aggressive, dominant males. Sneaker males usually face a number of disadvantages, including reduced access to females and the higher likelihood that upon ejaculation, their sperm face competition from other males. Nevertheless, sneaker males represent an evolutionarily stable strategy under a wide range of conditions. Game theory suggests that sneaker males compensate for these disadvantages by investing disproportionately in spermatogenesis, by producing more sperm per unit body mass (the "fair raffle") and/or by producing higher quality sperm (the "loaded raffle"). Here, we test these models by competing sperm from sneaker "jack" males against sperm from dominant "hooknose" males in Chinook salmon. Using two complementary approaches, we reject the fair raffle in favor of the loaded raffle and estimate that jack males were ?1.35 times as likely as hooknose males to fertilize eggs under controlled competitive conditions. Interestingly, the direction and magnitude of this skew in paternity shifted according to individual female egg donors, suggesting cryptic female choice could moderate the outcomes of sperm competition in this externally fertilizing species.

Interestingly, the direction and magnitude of this skew in paternity shifted according to individual female egg donors, suggesting cryptic female choice could moderate the outcomes of sperm competition in this externally fertilizing species.

    Purpose In male patients with congenital adrenal hyperplasia (CAH), the presence of testicular adrenal rest tumors (TARTs) have been reported, however their prevalence and clinical manifestations are not well known. Untreated TARTs may lead to testicular structural damage and infertility. This study was conducted to investigate the prevalence of TARTs in male patients with CAH, and characterize the manifestations to identify contributing factors to TART. Methods Among 102 CAH patients aged 0-30 years, 24 male patients have been regularly followed up in our outpatient clinic at Severance Children's Hospital from January 2000 to December 2014. In order to reveiw the characteristics of TART patients, we calculated the mean levels of hormones during the 5 years before the time of investigation. Five patients underwent follow-up scrotal ultrasonography (US) after adjusting the dosage of glucocorticoids. Results TARTs were detected in 8 of the 13 patients (61.5%). The median age of TARTs diagnosis was 20.2 years with the youngest case being 15.5 years old. The mean serum level of adrenocorticotropic hormone (ACTH) was higher in the TARTs patient group compared to the non-TARTs group (P<0.05). The tumor size decreased in 3 cases, slightly increased in 1 case, and had no change in another case. Conclusion The serum ACTH level might be associated with the growth promoting factor for TARTs, but the exact mechanism has not been clearly identified. Screening for TARTs using US is important in male patients with CAH for early-detection and prevention of ongoing complications, such as infertility. PMID:26512352

    Hybrid male sterility is a common barrier to gene flow between species. Previous studies have posited a link between misregulation of spermatogenesis genes in interspecies hybrids and sterility. However, in the absence of fully fertile control hybrids, it is impossible to differentiate between misregulation associated with sterility vs. fast male gene regulatory evolution. Here, we differentiate between these two possibilities using a D. pseudoobscura species pair that experiences unidirectional hybrid sterility. We identify genes uniquely misexpressed in sterile hybrid male reproductive tracts via RNA-seq. The sterile male hybrids had more misregulated and more over or under expressed genes relative to parental species than the fertile male hybrids. Proteases were the only gene ontology class overrepresented among uniquely misexpressed genes, with four located within a previously identified hybrid male sterility locus. This result highlights the potential role of a previously unexplored class of genes in interspecific hybrid male sterility and speciation. PMID:26146165

    Background Studies on adolescent idiopathic scoliosis have well documented the differences between natural history of male and female patients. There are also differences in responses to nonoperative treatment, but the results of operative treatment in male patients compared with females have not been widely reported. Only few studies had compared the outcomes of operative treatment between male and female patients with different results. Methods We retrospectively reviewed the outcome of 150 (112 girls and 38 boys) consecutive patients with diagnosis of adolescent idiopathic scoliosis who were managed surgically between May 1996 and September 2005. Next, male radiographic parameters were compared with female ones pre- and postoperatively. Then, a subgroup of 38 matched girls was compared regarding the age, curve type, curve magnitude, and the instrumentation we used. Results In comparing male patients with unmatched girls, the boys had greater mean age (17.3 ± 2.3 vs. 16.3 ± 2.9; p = 0.049), greater primary curve (71.4 ± 21.3° vs. 62.7 ± 17.5°; p = 0.013), less flexibility (30.1 ± 13.5% vs. 40.3 ± 17.8%; p = 0.01), and less correction percentage (51.3 ± 12.9% vs. 58.8 ± 16.5%; p = 0/013). The loss of correction was comparable between the two groups. In the matched comparison, the flexibility in boys was less than girls (30.1 ± 13.5% vs. 38.1 ± 17.5%; p = 0.027). Also, the boys had a smaller correction percentage compared to the girls, but this finding was not statistically significant. Conclusion There was similar distribution curve pattern between male and female patients with AIS. Males had more rigid primary curves compared to females but a similar degree of postoperative scoliosis correction. Male AIS patients were older at the time of surgery. These preoperative gender differences, however; did not compromise the radiological outcomes of surgical treatment and the results were comparable between the genders. PMID:18775076

  1. Conflict over Male Parentage in Social Insects

    PubMed Central

    2004-01-01

    Mutual policing is an important mechanism that maintains social harmony in group-living organisms by suppressing the selfish behavior of individuals. In social insects, workers police one another (worker-policing) by preventing individual workers from laying eggs that would otherwise develop into males. Within the framework of Hamilton's rule there are two explanations for worker-policing behavior. First, if worker reproduction is cost-free, worker-policing should occur only where workers are more closely related to queen- than to worker-produced male eggs (relatedness hypothesis). Second, if there are substantial costs to unchecked worker reproduction, worker-policing may occur to counteract these costs and increase colony efficiency (efficiency hypothesis). The first explanation predicts that patterns of the parentage of males (male parentage) are associated with relatedness, whereas the latter does not. We have investigated how male parentage varies with colony kin structure and colony size in 50 species of ants, bees, and wasps in a phylogenetically controlled comparative analysis. Our survey revealed that queens produced the majority of males in most of the species and that workers produced more than half of the males in less than 10% of species. Moreover, we show that male parentage does not vary with relatedness as predicted by the relatedness hypothesis. This indicates that intra- and interspecific variation in male parentage cannot be accounted for by the relatedness hypothesis alone and that increased colony efficiency is an important factor responsible for the evolution of worker-policing. Our study reveals greater harmony and more complex regulation of reproduction in social insect colonies than that expected from simple theoretical expectations based on relatedness only.

    Primary hyperparathyroidism (PHPT) is a disorder of calcium homeostasis. We report the case of a 17-year-old adolescent male, who presented with an acute psychosis coinciding with severe hypercalcemia and markedly elevated intact parathyroid hormone (iPTH) level and low vitamin D level. A Sestamibi scan showed a positive signal inferior to the left lobe of the thyroid gland. He had only a partial response to the initial medical and psychiatric management. The enlarged parathyroid gland was resected surgically and postoperatively serum calcium and iPTH levels normalized. The histopathology was compatible with a benign adenoma. Patient's acute psychotic symptoms resolved gradually after surgery; however he remained under psychiatric care for the behavioral issues for about 6 months after surgery. While psychosis is a rare clinical manifestation of hypercalcemia secondary to PHPT in pediatric population, it should be considered as a clinical clue in an otherwise asymptomatic pediatric patient.

    Male rejuvenation, defined as a process in men to both limit the impact of aging on body image and experience greater virility, is growing among middle-aged and older men. While rejuvenation was primarily in the domain of the younger male athlete with the use of performance enhancing hormones or in the aging woman through the use of cosmetic surgery, it is now more common among middle-aged and older men. Male rejuvenation can occur both through aesthetic surgical means and hormonal manipulation through anabolic steroid use. In this article, the authors review the psychological issues and perceptions surrounding male aesthetic surgeries and the resulting alteration of perception by peers and family; highlight the motives and desires behind the use of anabolic hormones at often supra-physiologic levels, and the intent to improve body image; and clarify the needs that remain to be examined in future research in this field.

    Male infertility has become an important public health problem worldwide. Nowadays the diagnosis of male infertility frequently depends on the results of semen quality or requires more invasive surgical intervention. Therefore, it is necessary to develop a novel approach for early diagnosis of male infertility. According to the presence or absence of normal sexual function, the male infertility is classified into two phenotypes, erectile dysfunction (ED) and semen abnormalities (SA). The aim of this study was to investigate the GC-MS plasma profiles of infertile male having erectile dysfunction (ED) and having semen abnormalities (SA) and discover the potential biomarkers. The plasma samples from healthy controls (HC) (n=61) and infertility patients with ED (n=26) or with SA (n=44) were analyzed by gas chromatography-mass spectrometry (GC-MS) for discrimination and screening potential biomarkers. The partial least squares-discriminant analysis (PLS-DA) was performed on GC-MS dataset. The results showed that HC could be discriminated from infertile cases having SA (AUC=86.96%, sensitivity=78.69%, specificity=84.09%, accuracy=80.95%) and infertile cases having ED (AUC=94.33%, sensitivity=80.33%, specificity=100%, accuracy=87.36%). Some potential biomarkers were successfully discovered by two commonly used variable selection methods, variable importance on projection (VIP) and original coefficients of PLS-DA (?). 1,5-Anhydro-sorbitol and ?-hydroxyisovaleric acid were identified as the potential biomarkers for distinguishing HC from the male infertility patients. Meanwhile, lactate, glutamate and cholesterol were the found to be the important variables to distinguish between patients with erectile dysfunction from those with semen abnormalities. The plasma metabolomics may be developed as a novel approach for fast, noninvasive, and acceptable diagnosis and characterization of male infertility. PMID:26592580

    2012-01-01

    Pre-determining fetal sex is against the random and equal opportunity that both conceptus sexes have by nature. Yet, under a wide variety of circumstances, populations shift their birth sex ratio from the expected unity. Here we show, using fluorescence in situ hybridization, that in a population of pygmy hippopotamus (Choeropsis liberiensis) with 42.5% male offspring, males bias the ratio of X- and Y-chromosome-bearing spermatozoa in their ejaculates, resulting in a 0.4337±0.0094 (mean±s.d.) proportion of Y-chromosome-bearing spermatozoa. Three alternative hypotheses for the shifted population sex ratio were compared: female counteract male, female indifferent, or male and female in agreement. We conclude that there appears little or no antagonistic sexual conflict, unexpected by prevailing theories. Our results indicate that males possess a mechanism to adjust the ratio of X- and Y-chromosome-bearing spermatozoa in the ejaculate, thereby substantially expanding currently known male options in sexual conflict.

    Most of the vocalizations of Antilopinae males are soft and usually only heard from a very close distance. The goitered gazelle is a rare exception to this rule, and during the rutting period territorial males of this species are among the noisiest antelopes. Rutting vocalization is such an essential part of the rutting behavior in goitered gazelle that adult males have a hypertrophic larynx, the muscle tissues of which increase considerably in size during the rut. We were interested in the frequency and variance with which male goitered gazelles emit their calls depending on an animal's age, reproductive status and time of the year in order to understand the main function of the rutting vocalizations. We found that roaring was mostly related to courting displays, while vocalizations during aggressive displays were less frequent in male-male interactions. Acoustic signals likely enhance courtship displays and also may aid in accelerating female ovulation, promoting synchronization of breeding cycles during the mating and birthing periods, which last only several days for most of the females in our population. We discuss the potential benefits of such behaviors and compare it to other species living in similarly extreme environments. PMID:24915642

    Background Multiple Sclerosis is more common in women than men and females have more relapses than men. In a large international cohort we have evaluated the effect of gender on disability accumulation and disease progression to determine if male MS patients have a worse clinical outcome than females. Methods Using the MSBase Registry, data from 15,826 MS patients from 25 countries was analysed. Changes in the severity of MS (EDSS) were compared between sexes using a repeated measures analysis in generalised linear mixed models. Kaplan-Meier analysis was used to test for sex difference in the time to reach EDSS milestones 3 and 6 and the secondary progressive MS. Results In relapse onset MS patients (n = 14,453), males progressed significantly faster in their EDSS than females (0.133 vs 0.112 per year, P<0.001,). Females had a reduced risk of secondary progressive MS (HR (95% CI) = 0.77 (0.67 to 0.90) P = 0.001). In primary progressive MS (n = 1,373), there was a significant increase in EDSS over time in males and females (P<0.001) but there was no significant sex effect on the annualized rate of EDSS change. Conclusion Among registrants of MSBase, male relapse-onset patients accumulate disability faster than female patients. In contrast, the rate of disability accumulation between male and female patients with primary progressive MS is similar. PMID:26046348

    One hundred and thirty-six cycles with a poor prognosis for full-term pregnancy underwent preimplantation genetic diagnosis (PGD) of aneuploidy. The mean maternal age was 31.8 +/- 2.5 years. Only patients younger than 36 years were included in the study with the aim of evaluating whether sperm indices have an effect on the chromosomal constitution of preimplantation embryos. No differences were detected in the percentage of aneuploid embryos; however a higher incidence of monosomies and trisomies was found in MESA-TESE embryos compared to the group of normospermic patients. In addition, an increase in the proportion of gonosomal aneuploidy seemed to be associated with the severity of the male factor parameters. The rate of de-novo chromosomal abnormalities in embryos from patients with a normal karyotype suggested an increased frequency proportional to the severity of the male factor condition, the proportion of monosomic and trisomic embryos, and the percentage of gonosomal aneuploidy increased accordingly. In the case of couples with a male altered karyotype, comparable frequency of chromosomally abnormal embryos, and monosomy and trisomy were observed irrespective of semen indices, gonosomal aneuploidy was only observed in one case where the patient had a karyotype with gonosomal mosaicism. These data confirm that the severe male infertility condition determines an increase in the rate of de-novo abnormalities, as anticipate by the follow-up of the children born after ICSI.

    Inbreeding depression results from mating among genetically related individuals and impairs reproductive success. The decrease in male mating success is usually attributed to an impact on multiple fitness-related traits that reduce the general condition of inbred males. Here, we find that the production of the male sex pheromone is reduced significantly by inbreeding in the butterfly Bicyclus anynana. Other traits indicative of the general condition, including flight performance, are also negatively affected in male butterflies by inbreeding. Yet, we unambiguously show that only the production of male pheromones affects mating success. Thus, this pheromone signal informs females about the inbreeding status of their mating partners. We also identify the specific chemical component (hexadecanal) probably responsible for the decrease in male mating success. Our results advocate giving increased attention to olfactory communication as a major causal factor of mate-choice decisions and sexual selection. PMID:23466986

    While the concept of male victimization is not a new phenomenon, the sexual assault of a male is a relatively new notion, emerging over the last 30 years in social research literature. Studies of female rape, pedophilia, and juvenile sex offenders have suggested that different styles of offending are reflected in the different types of behaviors committed by offenders at the crime scene. These studies suggest that there are three distinct themes of behavior: Control, Hostility, and Involvement. Using the crime scene actions of 305 male-on-male sexual assault from a U.K. national police database, multidimensional analysis was carried out. The proposed framework was found to be a useful way of classifying male-on-male sexual assaulters with 74% displaying a dominant theme. These resulted in 42% classified as displaying hostility, 23% as control, and 9% as involvement. Implications and suggestions for future research are discussed. PMID:24255070

    2015-01-01

    Background The auto-dissemination approach has been shown effective at treating cryptic refugia that remain unaffected by existing mosquito control methods. This approach relies on adult mosquito behavior to spread larvicide to breeding sites at levels that are lethal to immature mosquitoes. Prior studies demonstrate that ‘dissemination stations,’ deployed in mosquito-infested areas, can contaminate adult mosquitoes, which subsequently deliver the larvicide to breeding sites. In some situations, however, preventative measures are needed, e.g., to mitigate seasonal population increases. Here we examine a novel approach that combines elements of autocidal and auto-dissemination strategies by releasing artificially reared, male mosquitoes that are contaminated with an insecticide. Methodology Laboratory and field experiments examine for model-predicted impacts of pyriproxyfen (PPF) directly applied to adult male Aedes albopictus, including (1) the ability of PPF-treated males to cross-contaminate females and to (2) deliver PPF to breeding sites. Principal Findings Similar survivorship was observed in comparisons of PPF-treated and untreated males. Males contaminated both female adults and oviposition containers in field cage tests, at levels that eliminated immature survivorship. Field trials demonstrate an ability of PPF-treated males to transmit lethal doses to introduced oviposition containers, both in the presence and absence of indigenous females. A decline in the Ae. albopictus population was observed following the introduction of PPF-treated males, which was not observed in two untreated field sites. Conclusions/Significance The results demonstrate that, in cage and open field trials, adult male Ae. albopictus can tolerate PPF and contaminate, either directly or indirectly, adult females and immature breeding sites. The results support additional development of the proposed approach, in which male mosquitoes act as vehicles for insecticide delivery, including exploration of the approach with additional medically important mosquito species. The novelty and importance of this approach is an ability to safely achieve auto-dissemination at levels of intensity that may not be possible with an auto-dissemination approach that is based on indigenous females. Specifically, artificially-reared males can be released and sustained at any density required, so that the potential for impact is limited only by the practical logistics of mosquito rearing and release, rather than natural population densities and the self-limiting impact of an intervention upon them.

    DYNLT1 is a member of a gene family identified within the t-complex of the mouse, which has been linked with male germ cell development and function in the mouse and the fly. Though defects in the expression of this gene are associated with male sterility in both these models, there has been no study examining its association with spermatogenic defects in human males. In this study, we evaluated the levels of DYNLT1 and its expression product in the germ cells of fertile human males and males suffering from spermatogenic defects. We screened fertile (n = 14), asthenozoospermic (n = 15), oligozoospermic (n = 20) and teratozoospermic (n = 23) males using PCR and Western blot analysis. Semiquantitative PCR indicated either undetectable or significantly lower levels of expression of DYNLT1 in the germ cells from several patients from across the three infertility syndrome groups, when compared with that of fertile controls. DYNLT1 was localized on head, mid-piece, and tail segments of spermatozoa from fertile males. Spermatozoa from infertile males presented either a total absence of DYNLT1 or its absence in the tail region. Majority of the infertile individuals showed negligible levels of localization of DYNLT1 on the spermatozoa. Overexpression of DYNLT1 in GC1-spg cell line resulted in the up-regulation of several cytoskeletal proteins and molecular chaperones involved in cell cycle regulation. Defective expression of DYNLT1 was associated with male factor infertility syndromes in our study population. Proteome level changes in GC1-spg cells overexpressing DYNLT1 were suggestive of its possible function in germ cell development. We have discussed the implications of these observations in the light of the known functions of DYNLT1, which included protein trafficking, membrane vesiculation, cell cycle regulation, and stem cell differentiation.

  4. Female sticklebacks use male coloration in mate choice and hence avoid parasitized males

    1990-03-01

    AN important problem in evolutionary biology since the time of Darwin has been to understand why females preferentially mate with males handicapped by secondary sexual ornaments1-3. One hypothesis of sexual selection theory is that these ornaments reliably reveal the male's condition4-6, which can be affected for example by parasites4,7-13. Here we show that in the three-spined stickleback (Gasterosteus aculeatus) the intensity of male red breeding coloration positively correlates with physical condition. Gravid females base their active mate choice on the intensity of the male's red coloration. Choice experiments under green light prevent the use of red colour cues by females, and males that were previously preferred are now chosen no more than randomly, although the courtship behaviour of the males remains unchanged. Parasitieation causes a deterioration in the males' condition and a decrease in the intensity of their red coloration. Tests under both lighting conditions reveal that the females recognize the formerly parasitized males by the lower intensity of their breeding coloration. Female sticklebacks possibly select a male with a good capacity for paternal care14 but if there is additive genetic variation for parasite resistance, then they might also select for resistance genes, as proposed by Hamilton and Zuk4.

    Background Aedes aegypti, the principal vector of dengue fever, have been genetically engineered for use in a sterile insect control programme. To improve our understanding of the dispersal ecology of mosquitoes and to inform appropriate release strategies of ‘genetically sterile’ male Aedes aegypti detailed knowledge of the dispersal ability of the released insects is needed. Methodology/Principal Findings The dispersal ability of released ‘genetically sterile’ male Aedes aegypti at a field site in Brazil has been estimated. Dispersal kernels embedded within a generalized linear model framework were used to analyse data collected from three large scale mark release recapture studies. The methodology has been applied to previously published dispersal data to compare the dispersal ability of ‘genetically sterile’ male Aedes aegypti in contrasting environments. We parameterised dispersal kernels and estimated the mean distance travelled for insects in Brazil: 52.8m (95% CI: 49.9m, 56.8m) and Malaysia: 58.0m (95% CI: 51.1m, 71.0m). Conclusions/Significance Our results provide specific, detailed estimates of the dispersal characteristics of released ‘genetically sterile’ male Aedes aegypti in the field. The comparative analysis indicates that despite differing environments and recapture rates, key features of the insects’ dispersal kernels are conserved across the two studies. The results can be used to inform both risk assessments and release programmes using ‘genetically sterile’ male Aedes aegypti. PMID:26554922

    Many behaviors and physiological processes including locomotor activity, feeding, sleep, mating, and migration are dependent on daily or seasonally reoccurring, external stimuli. In D. melanogaster, one of the best-studied circadian behaviors is locomotion. The fruit fly is considered a diurnal (day active/night inactive) insect, based on locomotor-activity recordings of single, socially naive flies. We developed a new circadian paradigm that can simultaneously monitor two flies in simple social contexts. We find that heterosexual couples exhibit a drastically different locomotor-activity pattern than individual males, females, or homosexual couples. Specifically, male-female couples exhibit a brief rest phase around dusk but are highly active throughout the night and early morning. This distinct locomotor-activity rhythm is dependent on the clock genes and synchronized with close-proximity encounters, which reflect courtship, between the male and female. The close-proximity rhythm is dependent on the male and not the female and requires circadian oscillators in the brain and the antenna. Taken together, our data show that constant exposure to stimuli emanating from the female and received by the male olfactory and other sensory systems is responsible for the significant shift in intrinsic locomotor output of socially interacting flies.

    According to different geographical conditions, human health in different sub-regions of the world and cultural differences, the male factor infertility has heterogeneous causes in the world. This study was performed in an attempt to clarify the associated factors which might play a role in this respect in a group of Iranian infertile men. This study was a cross - sectional, descriptive and retrospective study. The information was obtained from the men who had attended the clinic from March 2004-2006. The factors which were studied in this research are the demographic characteristics, smoking, addiction, alcohol drinking, and exposure to lead, cimetidine and history of surgery. In 23.7 % of couples the cause of infertility was pure male factor and in 19.3 % of them the problem was related to male and female factor both. The most important associated factors for male factor included smoking (29%) and history of varicocele operation (22%). Since the quality of individual and social life is related to fertility state, it seems that more comprehensive studies on factors affecting male fertility at the community level are justified and recommended.

    Space use often correlates with reproductive success [1, 2]. Individual site fidelity is ubiquitous across a variety of taxa, including birds, mammals, insects, and reptiles [3-9]. Individuals can benefit from using the same area because doing so affords access to known resources, including food and/or breeding sites. The majority of studies on site fidelity have focused upon strictly territorial species in which individuals range in well-defined, exclusive areas (e.g., [4, 9]). By comparison, the transient groups that define fission-fusion species allow for considerable flexibility in individual space use. Although there is evidence that individual space use can influence reproductive success [2], relatively little is known about individual ranging patterns in fission-fusion species. Here, we investigate three potential correlates of male site fidelity (age, habitat quality, and maternal space use) in wild chimpanzees (Pan troglodytes). We found that when alone, each male preferentially concentrated his space use near the area where his mother ranged when he was dependent. We suggest that solitary ranging allows males to avoid direct competition with conspecifics and that foraging in familiar areas maximizes foraging efficiency. These results highlight the importance of male foraging strategies in a species in which male ranging is typically explained in terms of mating access to females. PMID:18158245

    Carcinoma of male breast constitutes 1% of total breast malignancy. Carcinoma arising from ectopic breast tissue in male is an extremely rare entity and can be misdiagnosed. Ectopic breast tissue may be supernumerary or aberrant one. Despite morphologic difference, ectopic breast tissue presents characteristics analogous to orthoptic breast in terms of functional and pathologic degeneration. Most of the ectopic breast tissue occurs in thoracic or abdominal portion of milk line. If found in a location outside the milk line, it proves a diagnostic dilemma. We are reporting a case of 60-year-old male who presented with a fixed mass of size 10cm×8cm, in right chest wall infraclavicular area of 6 months duration. Histopathology of the mass revealed invasive duct carcinoma. He had no evidence of malignant or occult primary lesion in the bilateral mammary glands. Due to the paucity of the literature, incidence of ectopic male breast cancer and its management is not well understood. There is high probability of misdiagnosis of this disease. To the best of our knowledge this is the first described case of ectopic male breast cancer in the chest wall, not along the milk line, which is being reported here for documentation. PMID:26436033

    At the international conference on Population and Development held in Cairo 1994, specific aspects of reproductive health addressed endorsed among others, were that unwanted pregnancies must always be given the highest priority and that every attempt should be made to eliminate the need for abortion. This paper focused on the involvement of males in promoting reproductive health through prevention of unplanned and unwanted pregnancies. A total of 71 males (48 adults and 23 adolescents) were selected conveniently from two health care centres, North of Tshwane, Gauteng province. Structured questionnaires having open and closed questions were used for data collection. Results indicated that most males (young and old) had general information about contraceptives and common side effects associated with contraceptive use. Despite this knowledge, only (29.2%) adults and almost half the number (50.0%) adolescents reportedly used condoms every time when having sex, whilst (35.0%) adults and only (13.6%) adolescents had never used condoms when having sex. Generally, males felt positive and wished to be involved in issues affecting their relationships, such as open communication about contraceptives used by their partners, discussing contraceptive problems together, planning families jointly with partner only, being informed about contraceptive failures and also playing a role in resolving such problems. Recommendations were made to encourage more visible involvement of males in promoting sexuality issues and reproductive health. PMID:17515319

    In sexual species, gametes have to find and recognize one another. Signaling is thus central to sexual reproduction and involves a rapidly evolving interplay of shared and divergent interests [1-4]. Among Caenorhabditis nematodes, three species have evolved self-fertilization, changing the balance of intersexual relations [5]. Males in these androdioecious species are rare, and the evolutionary interests of hermaphrodites dominate. Signaling has shifted accordingly, with females losing behavioral responses to males [6, 7] and males losing competitive abilities [8, 9]. Males in these species also show variable same-sex and autocopulatory mating behaviors [6, 10]. These behaviors could have evolved by relaxed selection on male function, accumulation of sexually antagonistic alleles that benefit hermaphrodites and harm males [5, 11], or neither of these, because androdioecy also reduces the ability of populations to respond to selection [12-14]. We have identified the genetic cause of a male-male mating behavior exhibited by geographically dispersed C. elegans isolates, wherein males mate with and deposit copulatory plugs on one another's excretory pores. We find a single locus of major effect that is explained by segregation of a loss-of-function mutation in an uncharacterized gene, plep-1, expressed in the excretory cell in both sexes. Males homozygous for the plep-1 mutation have excretory pores that are attractive or receptive to copulatory behavior of other males. Excretory pore plugs are injurious and hermaphrodite activity is compromised in plep-1 mutants, so the allele might be unconditionally deleterious, persisting in the population because the species' androdioecious mating system limits the reach of selection.

    Background Anticancer agents induce a variety of adverse effects when administered to cancer patients. Busulfan is a known antileukemia agent. When administered for treatment of leukemia in young patients, busulfan could cause damage to the male reproductive system as one of its adverse effects, resulting in sterility. Methods We investigated the effects of Korean Red Ginseng extract (KRGE) on busulfan-induced damage and/or dysfunction of the male reproductive system. Results We found that administration of busulfan to mice: decreased testis weight; caused testicular histological damage; reduced the total number of sperm, sperm motility, serum testosterone concentration; and eventually, litter size. Preadministration of KRGE partially attenuated various busulfan-induced damages to the male reproductive system. These results indicate that KRGE has a protective effect against busulfan-induced damage to the male reproduction system. Conclusion The present study shows a possibility that KRGE could be applied as a useful agent to prevent or protect the male reproductive system from the adverse side effects induced by administration of anticancer agents such as busulfan.

    One of four possible vignettes manipulated by (a) level of rape myth contained within them (low vs. high) and (b) type of rape (stranger vs. acquaintance) was presented to participants followed by scales measuring victim blame, perpetrator blame, belief in a just world, sex-role egalitarian beliefs, and male rape myth acceptance. Victim blaming was predicted by male rape myth acceptance. Perpetrator blaming was predicted by male rape myth acceptance and sex-role egalitarianism. Differences were found in victim and perpetrator blaming in terms of stranger and acquaintance rape and also in relation to manipulating the level of rape myths. Findings are discussed in relation to the previous literature on rape victim and perpetrator blaming. PMID:19738198

    Varicocele is a fairly common condition in male individuals. Although a minor disease, it may cause infertility and testicular pain. Consequently, it has high health and social impact. Here we review the current status of interventional radiology of male varicocele. We describe the radiological anatomy of gonadal veins and the clinical aspects of male varicocele, particularly the physical examination, which includes a new clinical and ultrasound Doppler maneuver. The surgical and radiological treatment options are also described with the focus on retrograde and antegrade sclerotherapy, together with our long experience with these procedures. Last, we compare the outcomes, recurrence and persistence rates, complications, procedure time and cost-effectiveness of each method. It clearly emerges from this analysis that there is a need for randomized multicentre trials designed to compare the various surgical and percutaneous techniques, all of which are aimed at occlusion of the anterior pampiniform plexus.

    2015-11-01

    The reproductive toxicity of environmental endocrine disruptors has attracted substantial attention from researchers in recent years. Bisphenol A (BPA) is among the most prominent environmental estrogens worldwide, demonstrated to be related with the impairment of male reproductive function as well as other health problems, such as diabetes, obesity, cardiovascular diseases, and cancer. BPA acts primarily by mimicking antiandrogenic and estrogenic effects, disturbing the hypothalamic-pituitary-testicular axis and modulating gene expressions and enzyme activities in the hormone biosynthesis affecting steroids or its receptors. BPA is also involved in DNA methylation and the effects of epigenetics, resulting in dyszoospermia, oligoasthenoteratospermia/azoospermia and/or infertility in males. This review addresses the effects of BPA on male reproductive function, focusing on the mechanisms of its toxicity on spermatogenesis, semen quality, and the reproductive system. PMID:26738332

    The plant life cycle alternates between a diploid sporophytic phase and haploid gametophytic phase, with the latter giving rise to the gametes. Male gametophyte development encompasses two mitotic divisions that results in a simple three-celled structure knows as the pollen grain, in which two sperm cells are encased within a larger vegetative cell. Both cell types exhibit a very different type of chromatin organization - highly condensed in sperm cell nuclei and highly diffuse in the vegetative cell. Distinct classes of histone variants have dynamic and differential expression in the two cell lineages of the male gametophyte. Here we review how the dynamics of histone variants are linked to reprogramming of chromatin activities in the male gametophyte, compaction of the sperm cell genome and zygotic transitions post-fertilization.

    Several studies have shown female preference for conspecific males with the attached artificial ornaments of more elaborate heterospecifics. However, preference for heterospecifics under natural conditions is relatively rare. We tested what factors affect behavioural mechanisms of species isolation using three species of estrildid finch (genus Uraeginthus) that occur in both sympatry and allopatry. These finches differ in degree of sexual dimorphism; male ornamentation; behavioural and morphological similarity; and phylogenetic distance. Paired mate-choice trials were used in which females were presented with a conspecific and heterospecific male to test which of the above between-species differences best predicted the degree of premating isolation. The three species differed in the degree of species-specific mate preference shown. Females from the brighter two species discriminated against dull males, independently of sympatry-allopatry, similarity and phylogenetic distance. Females from the dull species reacted to conspecific males and brighter heterospecific males equally strongly, independently of similarity and phylogenetic distance. In contrast to previous studies, an equal preference for heterospecific and conspecific males was found under natural conditions. It is suggested that differences between closely related species in male ornamentation affect the likelihood that premating isolation will occur due to the fact that sexual selection tends to drive preferences for exaggerated ornamentation.

    2014-03-01

    In their choice of mates, females may use alternative tactics, including a comparative assessment of males in a population, using one or several relative preference criteria. Traits involved in female choice should presumably be variable between, but not within males, thus potentially providing reliable cues of male identity and quality for prospecting females. In lekking species, sexual selection is usually intense, and females can freely choose mates. Studying the Little Bustard Tetrax tetrax, a bird with an exploded lek mating system, we first identified male phenotypic traits that showed higher among, than within variation (plumage pattern, display rates and call structure). Among those and other traits (ornaments and their symmetry, body condition, lek spatial organization and territory quality), we identified phenotypic traits that correlated with male attractiveness toward females. At least four phenotypic male traits were correlated with female attraction, i.e. body condition, lek attendance, ornamental symmetry and display rates. Traits related to the initial female attraction on male territory seem to differ from traits related to the decision of females to stay in the territory of attractive males. PMID:24440985

  7. Inbreeding depression in male gametic performance.

    Losdat, S; Chang, S-M; Reid, J M

    2014-06-01

    One key objective in evolutionary ecology is to understand the magnitude of inbreeding depression expressed across sex-specific components of fitness. One major component of male fitness is fertilization success, which depends on male gametic performance (sperm and pollen performance in animals and plants, respectively). Inbreeding depression in male gametic performance could create sex-specific inbreeding depression in fitness, increase the benefit of inbreeding avoidance and reduce the efficacy of artificial insemination and pollination. However, there has been no assessment of the degree to which inbreeding generally depresses male gametic performance and hence post-copulatory or post-pollination fertilization success. Because inbreeding depression is understood to be a property of diploid entities, it is not clear what degree of inbreeding depression in haploid gametic performance should be expected. Here, we first summarize how inbreeding depression in male gametic performance could potentially arise through gene expression in associated diploid cells and/or reduced genetic diversity among haploid gametes. We then review published studies that estimate the magnitude of inbreeding depression in traits measuring components of sperm or pollen quantity, quality and competitiveness. Across 51 published studies covering 183 study traits, the grand mean inbreeding load was approximately one haploid lethal equivalent, suggesting that inbreeding depresses male gametic performance across diverse systems and traits. However, there was an almost complete lack of explicit estimates from wild populations. Future studies should quantify inbreeding depression in systematic sets of gametic traits under naturally competitive and noncompetitive conditions and quantify the degree to which gamete phenotypes and performance reflect haploid vs. diploid gene expression.

    Background: Male breast cancer (MBC) is a rare disease and little is known about its etiopathogenesis. Array comparative genomic hybridization (aCGH) provides a method to quantitatively measure the changes of DNA copy number and to map them directly onto the complete linear genome sequences. The aim of this study was to investigate DNA imbalances by aCGH and compare them with a female breast cancer dataset. Methods: We used Agilent Human Genome CGH Microarray Kit 44B and 44K to compare genomic alterations in 25 male breast cancer tissues studied at NCC of Bari and 16 female breast cancer deposited with the Gene Expression Omnibus (GSE12659). Data analysis was performed with Nexus Copy Number 5.0 software. Results: All the 25 male and 16 female breast cancer samples displayed some chromosomal instability (110.93 alterations per patient in female, 69 in male). However, male samples presented a lower frequency of genetic alterations both in terms of loss and gains. Conclusion: aCGH is an effective tool for analysis of cytogenetic aberrations in MBC, which involves different biological processes than female. Male most significant altered regions contained genes involved in cell communication, cell division and immunological response, while female cell–cell junction maintenance, regulation of transcription and neuron development.

    Traditional Chinese medicine (TCM) is an important treatment for male infertility, and its application to therapy is dependent on differentiation of TCM syndromes. This study aims to investigate the changes in metabolites and metabolic pathways in infertile males with Kidney-Yang Deficiency syndrome (KYDS) via metabolomics approaches. Seminal plasma samples were collected from 18 infertile males with KYDS and 18 fertile males. Liquid chromatography and mass spectrometry were used to characterize metabolomics profiles. Principal component analysis (PCA), partial least squares-discriminate analysis (PLS-DA), and pathway analysis were used for pattern recognition and metabolite identification. PCA and PLS-DA results differentiated the two groups of patients. Forty-one discriminating metabolites (18 in positive mode and 23 in negative mode) were identified. Seven metabolites were related to five potential metabolic pathways associated with biosynthesis and metabolism of aromatic amino acids, tricarboxylic acid cycle, and sphingolipid metabolism. The changes in metabolic pathways may play an important role in the origin of KYDS-associated male infertility. Metabolomics analysis of seminal plasma may be used to differentiate TCM syndromes of infertile males, but further research must be conducted. PMID:25945117

    Several studies showed that the genetic mutations in the folate-related enzyme genes might be associated with male infertility; however, the results were still inconsistent. We performed a meta-analysis with trial sequential analysis to investigate the associations between the MTHFR C677T, MTHFR A1298C, MTR A2756G, MTRR A66G mutations and the MTHFR haplotype with the risk of male infertility. Overall, a total of 37 studies were selected. Our meta-analysis showed that the MTHFR C677T mutation was a risk factor for male infertility in both azoospermia and oligoasthenoteratozoospermia patients, especially in Asian population. Men carrying the MTHFR TC haplotype were most liable to suffer infertility while those with CC haplotype had lowest risk. On the other hand, the MTHFR A1298C mutation was not related to male infertility. MTR A2756G and MTRR A66G were potential candidates in the pathogenesis of male infertility, but more case-control studies were required to avoid false-positive outcomes. All of these results were confirmed by the trial sequential analysis. Finally, our meta-analysis with trial sequential analysis proved that the genetic mutations in the folate-related enzyme genes played a significant role in male infertility. PMID:26549413

    As the United States has become more multicultural and diverse, there has been an increase in violence motivated by hate. Hate crimes against gay males are the most prevalent of the hate crimes based on sexual orientation. Hate crimes have their roots in normative, individual, and societal attitudes and ideologies that lead to intimidation, bullying, teasing, physical assault, rape, and murder. This paper provides an overview of the issues specific to hate crime assaults against gay males. Mental health nurses may find this knowledge useful in developing further nursing inquiry, education, and clinical practice related to hate crime and violence prevention. PMID:14726266

    In a study of performance-enhancing substance use among 231 experienced young male weightlifters, we found that 27 (12%) reported illicit use of human growth hormone (HGH) or its bioactive derivative, insulin-like growth factor-1 (IGF-I). All of these 27 men also reported use of anabolic-androgenic steroids (AAS) and 22 (81%) met criteria for current or past AAS dependence. Fifteen (56%) also reported current or past dependence on opioids, cocaine, and/or ecstasy. These findings suggest that among young male weightlifters, illicit HGH use has become a common form of substance abuse, frequently associated with both AAS dependence and classical substance dependence.

    The aim was to understand experiences of male competitive bodybuilders from a non-pathologizing perspective. Six male Norwegian competitive bodybuilders were interviewed. The interviews were analysed using a meaning condensation procedure resulting in five themes: being proud of capacity for discipline, seeing a perfectionist attitude as a necessary evil, experiencing recognition within the bodybuilding community, being stigmatized outside the bodybuilding community and going on stage to display a capacity for willpower and discipline. We suggest that bodybuilders may be stigmatized for breaking social norms: by their distinctive appearance, by the way they handle suspected drug use and by challenging gender norms. PMID:23682065

    The purpose of this paper is to describe pertinent non-medical circumstances around male-on-male sexual assault, and supplements the earlier article in this journal regarding forensic medical aspects of this population. As services (medical, policing and judicial) see more males they will need to adapt themselves to their needs as well as those of their female clients. St. Mary's Sexual Assault Referral Centre (Greater Manchester, UK) opened in October 1986. Up to May 2003 it had seen 376 male (370 individual clients) and 7,789 female cases (7,403 clients). Of these, significantly fewer males reported to the police than females, although this difference has disappeared in recent years. There were also significant differences between the sexes regarding relationship, number of assailants, and assault location. There were no statistically significant differences between the sexes for age of the client, and presence in the assault of weapons or additional violence. PMID:16117283

    Male to female transsexuals frequently seek feminizing vaginoplasty for “below the waist” conformation, enhancement of sexual identity, and interactive sexual function. The author shares his experience with his first 250 primary surgical procedures. Included is a brief historical background, the patient selection process, some guidelines from the World Professional Association for Transgender Health (standards of care), preoperative evaluation and instructions, surgical technique, postoperative regimen, risk factors, results, complications and management. The patients all underwent feminizing vaginoplasty at the author's ambulatory surgical facility, which includes an overnight stay. The author's results suggest that feminizing vaginoplasty when performed vigilantly on a select group of patients is feasible. PMID:22547974

    Objective: Sperm analysis is an important step to evaluate and diagnose male’s infertility. The present study aimed to determine associated factors with males’ infertility by using semen analysis. Materials and Methods: In this study 96 men were evaluated who attended to the infertility clinics of Ilam province, western Iran between May 2010 to May 2011. Semen analysis was done using the Weili Dynamic Sperm Analysis software adapted to the WHO classification. Based on movement and speed characters, sperms were classified to either A, B, C or D classes. Participants were stratified into two groups that called “Oligospermia (OS)” with sperm counts of less than 20 million in mL (n=48) and “Non-Oligospermia (NOS)” with values more than determined cutoff point (n=48). Results: The Mean age ±SD for OS and NOS group were 29.9 ±5.1 y and 31.17 ±5.24 y, respectively (p>0.05). Overall, 62.5% of OS and 31.2% of NOS were clinically infertile (OR=3.6, CI, 1.5-8.5, p=0.01). A significant difference was found between job and live ratio(A+B+C) in NOS group (F=2.8, p<0.05). Conclusion: Prevalence of infertility was higher in the OS men compared to the NOS group. The main risk factors in the OS group were History of Varicocele surgery and residence site of patients that are totally similar to the NOS men. Further case-control studies and clinical trials are recommended to recognize infertility causes in men. PMID:25386439

    Progranulin (GRN) gene variability has been analyzed in a sample of 354 patients with multiple sclerosis (MS) compared with 343 controls. No significant differences were observed, but by stratifying according to MS subtypes, a significant increased frequency of the rs2879096 TT genotype was found in primary progressive MS (PPMS) patients versus controls (16.0 vs 3.5%, P=0.023, odds ratio (OR) 5.2, 95% confidence interval (CI) 1.2-21.4). In addition, in PPMS, an association with the C allele of rs4792938 was observed (55.3 vs 33.5%, P=0.011, OR 2.4, 95% CI 1.2-4.7). An independent population was studied as replication, failing to confirm results previously obtained. Stratifying according to gender, an association with rs4792938 C allele was found in male PPMS patients compared with controls (40.7 vs 26.9%, P=0.002, OR 1.87, 95% CI 1.2-2.8). An association with the rs2879096T allele was observed (29.2 in patients compared with 18.9% in controls, P=0.012, OR 1.77, 95% CI 1.1-2.8). Haplotype analysis showed that TC haplotype frequency is increased in PPMS male patients compared with male controls (25.7 vs 16.6%; P=0.02, OR 1.69, 95% CI 1.1-2.7), whereas the respective GC haplotype seems to exert a protective effect, as its frequency is decreased in patients compared with controls (55.8% vs 70.9%; P=0.001, OR 0.52, 95% CI 0.4-0.8). Therefore, GRN haplotypes likely influence the risk of developing PPMS in males. PMID:20463744

    Myofibroblastoma of the breast (MFB) is a very rare benign stromal tumor. In recent years, increase in mammographic screenings has resulted in increased diagnosis of MFB. Most cases are old males and postmenopausal women. MFB may be confused as malignant, clinically, morphologically, or by imaging. Immunohistochemistry is essential for final diagnosis in these cases. We report a case of a pathologically diagnosed MFB in an 80-year-old male patient who had coexisting prostate cancer and describe its imaging characteristics, especially magnetic resonance imaging (MRI). In this paper, histopathological and MRI findings of the MFB were discussed. PMID:26294999

    The objective of this investigation was to establish clinical 'norms' of craniofacial skeletal orientation and the associated soft tissue facial profile for adult white males. Lateral and frontal cephalometric radiographs and study casts taken on 305 white males, with 28 or more teeth and 25-75 years of age, were used to develop these craniofacial standards. The goal of the research program has been to develop a computerized approach based upon dentofacial templates for the fabrication of complete dentures and to define clinical standards that can be applied in assessing the prosthodontic and orthodontic treatment needs of adult patients.

    We have developed a protocol for the identification of aberrant chromosome behavior during human male meiosis up to metaphase of the secondary spermatocyte. Histological evaluation by the Johnsen score of a testicular biopsy was combined with immunofluorescence of first meiotic prophase spermatocytes, using antibodies against synaptonemal complex protein 3 (SYCP3) and the product of the ataxia telangiectasia and rad3-related gene (ATR). This combination enables accurate meiotic prophase substaging and the identification of pachytene spermatocytes with asynapsis. Furthermore, we also investigated the competence of late pachytene primary spermatocytes to complete the first meiotic division up to metaphase and of secondary spermatocytes to transform into metaphase by an in vitro challenge with okadaic acid (OA). We tested this protocol on five males with normal Johnsen scores that presented with obstructive azoospermia, five males with low Johnsen scores and non-obstructive azoospermia and six vasectomized control males of proven fertility and normal Johnsen scores. In all azoospermics, the profiling of meiotic prophase stages by immunofluorescence increases the resolving power of the Johnsen score. In both obstructive and non-obstructive azoospermic patients, relatively more leptotene meiotic prophase stages were counted compared to the controls. In non-obstructive azoospermics, a marked heterogeneity in spermatogenesis was found, after combining the results of all three approaches, pointing at functional mosaicism of the germinal epithelium. Asynaptic pachytene spermatocytes were rarely encountered. Also, when first meiotic metaphase could be induced by OA, chiasma counts were normal. In none of the non-obstructive azoospermic males did the pattern of spermatogenesis resemble that of knock-out mouse azoospermics. We conclude that this combined histological and cytological approach enables a detailed phenotypic classification of infertile males, at a level comparable to that applied for male-sterile knock-out mice with a meiotic defect. This may facilitate the identification of candidate genes for human male infertility. PMID:15218256

    2015-05-01

    Infertility derived from mate etiology is a health problem which has increased over the last decades. Varicocele is a common cause for mate infertility with incidence of 35% and 75% among males with primary and secondary infertility, respectively, compared to 10%-15% among the general population. VaricoceLe is defined as dilated and entangled pampiniform plexus and internal spermatic veins located in the spermatic cord. The effect of varicocele on male infertility was controversial due to lack of published data uniformity and high standard studies. During recent years several published researches supplied reliable evidence regarding the influence of varicocele on mate infertility, treatment options and appropriate indications. Adequate patient selection significantly improves the chances for spontaneous pregnancy. Treatment varies between surgical veins ligation by various means and embolization by the endovascular approlch of the dilated veins. The current article summarizes updated treatment indications, advantages and drawbacks of the optional approaches and describes the considerations for choosing the optimal treatment for the infertile couple due to varicocele.

    The Beckwith-Wiedemann syndrome (BWS) is a multiple congenital anomaly syndrome characterized by macrosomia, macro glossia, visceromegaly, characteristic facies, and in some cases omphalocele, hypoglycemia, hemihypertrophy, and risk of embryonal tumors. Most cases occur sporadically in chromosomally normal individuals, but a few BWS patients have anomalies of 11p and others have evidence of microduplications or paternal isodisomy in this region. In some families with autosomal dominant transmission, BWS maps to 11p15.5, but the mechanism of transmission is not fully understood. BWS has been reported in 11 sets of MZ twins, including 10 female pairs (9 discordant and 1 partially concordant) and one male pair concordant for both BWS & dup 15q11.2-q13. We report a pair of premature male MZ twins with macroglossia, postnatal overgrowth, characteristic BWS facies, and mild developmental delay. One twin had hypoglycemia, but neither had omphalocele or hemihypertrophy and serial abdominal ultrasounds have been normal. DNA fingerprinting confirmed monozygosity. Chromosome studies showed a marker 11p14.2 in one twin only, and molecular genetic studies of the 11p15.5 region showed no evidence of duplication or isodisomy in either twin.

    Society places great emphasis on the presence of hair. Some degree of hair loss is accepted as a normal part of the aging process, in line with the observation that more than 50% of men will develop androgenetic alopecia by the age of 50 years. However, it is possible to understand the psychosocial isolation and distress felt by men with a strong familial predisposition to androgenetic alopecia, who tend to display hair loss in their late teens or twenties. There are currently two drugs which have been licensed for the treatment of male androgenetic alopecia: oral finasteride and topical minoxidil solution which are effective to some extent. Furthermore, upon discontinuing treatment, any gain that has been achieved is quickly lost. Added to which there is an entire market of unproven over the counter products: advertised in the electronic media, local hair salons, and various departmental stores. In this review, we highlight the important advances in the management of male androgenetic alopecia with emphasis on approaches that can lead to more successful and long-term hair restoration for young adults. In particular, we discuss the evidence supporting the use of the follicular unit grafting technique in conjunction with medical treatment before and after the procedure. Moreover, some other alterations of this most popular state of the art hair restoration technique have been mentioned briefly. As a result, patients and physicians seem equally satisfied from this procedure for its naturally looking results which are cosmetically more acceptable and esthetically pleasing for longer period of time.

    A prospective clinical study was performed in the reproduction centre of Ichikawa General Hospital (Chiba, Japan) to investigate the relationship between sperm quality and serum oestradiol (E2) level in male partners of infertile couples. The semen parameters and blood samples were assessed in relation to several variables, including body mass index (BMI) and serum oestradiol (E2) levels. Four hundred and nine male partners of infertile couples aged 22-55 years (mean: 36.5 years) were referred to the reproduction centre. In total, 143 patients (35.0%) were included in the low E2 level group (18 pg ml(-1) ? E2). Serum E2 levels were slightly correlated with testosterone levels, BMI and serum FSH levels. Total motile sperm count and morphology were decreased in low E2 level group. In multivariate analysis, serum testosterone, E2 levels, existence of varicocele and age were risk factors for decreased semen quality. Serum E2 might be associated with BMI, serum testosterone level and spermatogenesis. PMID:25059733

    Salmon produced by hatcheries have lower fitness in the wild than naturally produced salmon, but the factors underlying this difference remain an active area of research. We used genetic parentage analysis of alevins produced by experimentally mixed groups of wild and hatchery coho salmon (Oncorhynchus kisutch) to quantify male paternity in spawning hierarchies. We identify factors influencing paternity and revise previously published behavioural estimates of reproductive success for wild and hatchery males. We observed a strong effect of hierarchy size and hierarchy position on paternity: in two-male hierarchies, the first male sired 63% (±29%; s.d.) of the alevins and the second male 37% (±29%); in three-male hierarchies, the first male sired 64% (±26%), the second male 24% (±20%) and the third male 12% (±10%). As previously documented, hatchery males hold inferior positions in spawning hierarchies, but we also discovered that hatchery males had only 55–84% the paternity of wild males when occupying the same position within a spawning hierarchy. This paternity difference may result from inferior performance of hatchery males during sperm competition, female mate choice for wild males, or differential offspring survival. Regardless of its cause, the combination of inferior hierarchical position and inferior success at a position resulted in hatchery males having only half (51%) the reproductive success of wild males.

    Chromosomal analyses were performed from peripheral blood samples from 20 adult rabbit males from Line R. This line has been selected for growth rate after weaning through 25 generations. Seminal characteristics and reproductive outcomes from these males were also examined. The chromosomal analysis results showed that one male had an aneuploidy rate of 16% (male A). The aneuploidies found represented both hypo- and hyper- haploidy. Differences between the male A and the contemporary males (males N), in fertility at 12 days post-insemination (44% vs. 66%) and at birth (31% vs. 59%) were observed. The male A also showed a high percentage of pregnancy losses (29% vs. 12%). For seminal characteristics, the percentage of abnormal spermatozoa was statistically different (P<0.05) between male A and males N (34+/-4 vs. 18+/-2), and concentration differed significantly between males, showing the male A reduced fewer spermatozoa than males N (67+/-23 vs. 172+/-10, x106/ml). Motility and kinematic parameters revealed no differences between males. Differences between male reproductive performance found in this study could be explained by the effect of aneuploidy on spermatogenesis and its deleterious effect on male reproduction. PMID:20207408

    Sex steroids are chief regulators of gender differences in the skeleton, and male gender is one of the strongest protective factors against osteoporotic fractures. This advantage in bone strength relies mainly on greater cortical bone expansion during pubertal peak bone mass acquisition and superior skeletal maintenance during aging. During both these phases, estrogens acting via estrogen receptor-? in osteoblast lineage cells are crucial for male cortical and trabecular bone, as evident from conditional genetic mouse models, epidemiological studies, rare genetic conditions, genome-wide meta-analyses, and recent interventional trials. Genetic mouse models have also demonstrated a direct role for androgens independent of aromatization on trabecular bone via the androgen receptor in osteoblasts and osteocytes, although the target cell for their key effects on periosteal bone formation remains elusive. Low serum estradiol predicts incident fractures, but the highest risk occurs in men with additionally low T and high SHBG. Still, the possible clinical utility of serum sex steroids for fracture prediction is unknown. It is likely that sex steroid actions on male bone metabolism rely also on extraskeletal mechanisms and cross talk with other signaling pathways. We propose that estrogens influence fracture risk in aging men via direct effects on bone, whereas androgens exert an additional antifracture effect mainly via extraskeletal parameters such as muscle mass and propensity to fall. Given the demographic trends of increased longevity and consequent rise of osteoporosis, an increased understanding of how sex steroids influence male bone health remains a high research priority.

    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.

    1985-02-01

    To investigate risk factors in male breast cancer, a case-control study of 52 histologically diagnosed cases and 52 controls--matched for age, race, marital status, and hospital--was conducted in 5 U.S. metropolitan areas. Cases were significantly more likely to be Jewish than were the controls, supporting earlier suggestions of an increased risk in Jewish males. A significant association of male breast cancer with mumps infections at age 20 years or older, along with the possible association with antecedent testicular injury and the excess frequency of mumps orchitis among cases, suggests that testicular factors may be important in the development of breast cancer among males. An increased frequency of breast cancer among persons who have worked in blast furnaces, steel works, and rolling mills is of interest because of the possible testicular effect of high environmental temperatures. The observed association between breast cancer and a prior history of swollen breast is difficult to interpret because of potential recall bias, and a possible relationship with military service needs further confirmation.

    The study found that mentally retarded males (N=18) above 12 years of age with a fragile site on the X chromosome exhibited a highly idiosyncratic stereotypic form of gaze avoidance during greeting ceremonies. Results suggest this aberrant greeting behavior may be uniquely associated with this syndrome of mental retardation. (Author/DB)

    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.

  11. Epidemiologic methods for investigating male fecundity

    Fertility is a couple concept that has been measured since the beginning of demography, and male fecundity (his biological capacity to reproduce) is a component of the fertility rate. Unfortunately, we have no way of measuring the male component directly, although several indirect markers can be used. Population registers can be used to monitor the proportion of childless couples, couples who receive donor semen, trends in dizygotic twinning, and infertility diagnoses. Studies using time-to-pregnancy (TTP) may identify couple subfecundity, and TTP data will correlate with sperm quality and quantity as well as sexual activity and a number of other conditions. Having exposure data available for couples with a fecund female partner would make TTP studies of interest in identifying exposures that may affect male fecundity. Biological indicators such as sperm quality and quantity isolate the male component of fertility, and semen data therefore remain an important source of information for research. Unfortunately, often over half of those invited to provide a sperm sample will refuse, and the study is then subject to a selection that may introduce bias. Because the most important time windows for exposures that impair semen production could be early fetal life, puberty, and the time of ejaculation; longitudinal data over decades of time are required. The ongoing monitoring of semen quality and quantity should continue, and surveys monitoring fertility and waiting TTP should also be designed. PMID:24369129

    Melatonin is a hormone produced by the pineal gland. There is much controversy about its relationship to the male reproductive process. In this study, seminal plasma as well as the serum melatonin levels were studied in different infertile male groups and were correlated with their semen parameters and hormonal levels. One hundred twenty male cases subdivided into six equal groups were consecutively included; fertile normozoospermic men, oligoasthenozoospermia (OA), OA with leucocytospermia, OA with varicocele, non-obstructive azoospermia (NOA) with high serum follicle stimulating hormone (FSH) and NOA with normal FSH. Semen analysis, estimation of melatonin, FSH, testosterone (T) and prolactin (PRL) hormone was carried out. Mean level of serum melatonin was higher than its corresponding seminal concentrations in all investigated groups with a positive correlation between their levels (r = 0.532, p = 0.01). Serum and seminal plasma melatonin levels in all infertile groups were reduced significantly compared with their levels in the fertile group. The lowest concentrations were in OA with leucocytospermia group. Melatonin in both serum and semen demonstrated significant correlation with sperm motility (r = 607, 0.623 respectively, p = 0.01). Serum melatonin correlated positively with serum PRL (r = 0.611, p = 0.01). It may be concluded that melatonin may be involved in the modulation of reproductive neuroendocrine axis in male infertility. Also, low levels of melatonin in semen were observed in infertile groups having reduced sperm motility, leucocytospermia, varicocele and NOA. PMID:16371109

    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.

    Mammary duct ectasia/periductal mastitis is exceedingly rare in males. Ten cases have been reported in the literature, the last 2 cases were associated with Human immunodeficiency virus. The previously reported cases presented in females with blood stained discharge or subareolar inflammatory process. All cases required surgical treatment, 7 out of 10 cases underwent a form of mastectomy. To the best of our knowledge this disease entity was not reported in patients suffering from Behcets disease. This article described 2 new cases, one of them is a young man who had associated Behcets disease. An immune mechanism may be responsible for such association, which was not reported before. The clinical presentation, pathological findings and management of these 2 new cases were outlined followed by literature review. PMID:11744981

    Hypertensive encephalopathy is believed to be caused by an abrupt elevation in systemic blood pressure. It rarely occurs in children and can be neurologically devastating if it is not recognized and treated immediately. This report describes an 11-year-old male who presented with edema and a cerebellar lesion, with acute obstructive hydrocephalus resulting from hypertensive encephalopathy. A shunt was inserted to relieve pressure in the acute stage. The patient's hydrocephalus and cerebellar swelling subsided when his blood pressure was controlled. The cerebellar lesion had been initially diagnosed as a glioma. In children, a cerebellar lesion occurring with acute obstructive hydrocephalus and hypertensive encephalopathy is rare but reversible. Clinicians should be aware of this condition because it might be misdiagnosed as a tumor of the posterior fossa. PMID:16376285

    Two hundred ischemic stroke patients and 193 age and sex matched healthy controls were studied for the presence of Angiotensin Converting Enzyme Insertion/Deletion (ACE I/D) gene polymorphism. The PCR studies revealed that ACE ‘II’ (OR = 2.055; p = 0.004) genotype and ‘I’ (OR = 1.411; p = 0.018) alleles were significantly associated with IS patients. Gender specific analysis revealed a strong association of ‘II’ (OR = 2.044; p = 0.014) genotype and ‘I’ (OR = 1.531; p = 0.011) allele with male sex. Classification of patients based on TOAST criteria, revealed a significant association for ‘II’ genotype (OR = 1.713; p = 0.043) and ‘I’ (OR = 1.382; p = 0.039) allele in LVD patients only. When the data was stratified based on age and sex, a statistically significant association was observed for ACE ‘II’ genotype (OR = 2.288; p = 0.006) and ‘I’ allele (OR = 1.395; p = 0.054) in IS male patients of > 50 years of age. The ACE ‘D’ allele was found to be increased in controls (OR = 0.709; p = 0.018) than IS patients. Multivariate logistic regression analysis showed that smoking and diabetes were the most powerful independent risk factor in LVD type of stroke. Thus, we presented here an evidence for a strong association of ACE ‘II’ genotype and ‘I’ allele compounded by factors such as smoking and diabetes among south Indian IS patients. PMID:25606450

    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), ?-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 boron displayed a significant loss of germinal elements, although most of the Leydig and Sertoli cells appeared normal. Testicular atrophy was associated with a decrease in seminiferous tubular diameter and a marked reduction of spermatocytes and spermatogenic cells. These morphologic alterations were associated with a concomitant reduction of H, SDH, and LDH-X specific activities. In contrast, the specific activities of G3PDH and MDH were significantly elevated above control. The increase in these enzyme activities can be attributed to the relative enrichment of spermatogonial cells during the loss of spermatocytes and spermiogenic cells. Boron-induced male germinal aplasia was also associated with significantly elevated plasma FSH while plasma LH and testosterone levels were not significantly altered. Plasma testosterone levels were unaltered. Male fertility studies demonstrated that at the 500 ppm boron level, fertility was unaffected. However, at 1000 and 2000 ppm boron, male fertility was significantly reduced. Most effects were reversible within 5 weeks. However, the male group receiving 2000 ppm boron for 60 days remained sterile. There was no dose-related decrease in litter size or fetal death in utero. Therefore, the boron-induced infertility was apparently not due to a dominant lethal effect but rather to germinal aplasia. Boron appears toxic to spermatogenic cells at testicular concentrations of 6–8 ppm. ImagesFIGURE 6.FIGURE 9. PMID:446458

    Male house mice (Mus musculus) emit ultrasonic vocalizations (USVs) during courtship, which attract females, and we aimed to test whether females use these vocalizations for species or subspecies recognition of potential mates. We recorded courtship USVs of males from different Mus species, Mus musculus subspecies, and populations (F1 offspring of wild-caught Mus musculus musculus, Mus musculus domesticus (and F1 hybrid crosses), and Mus spicilegus), and we conducted playback experiments to measure female preferences for male USVs. Male vocalizations contained at least seven distinct syllable types, whose frequency of occurrence varied among species, subspecies, and populations. Detailed analyses of multiple common syllable types indicated that Mus musculus and Mus spicilegus could be discriminated based on spectral and temporal characteristics of their vocalizations, and populations of Mus musculus were also distinctive regardless of the classification model used. Females were able to discriminate USVs from different species, and showed assortative preferences for conspecific males. We found no evidence that females discriminate USVs of males from a different subspecies or separate populations of the same species, even though our spectral analyses identified acoustic features that differ between species, subspecies, and populations of the same species. Our results provide the first comparison of USVs between Mus species or between Mus musculus subspecies, and the first evidence that male USVs potentially facilitate species recognition.

    Specialized signals emitted by competing males often convey honest information about fighting ability. It is generally believed that receivers use these signals to directly assess their opponents. Here, we demonstrate an alternative communication strategy used by males in a breeding system where the costs of conflict are extreme. We evaluated the acoustic displays of breeding male northern elephant seals (Mirounga angustirostris), and found that social knowledge gained through prior experience with signallers was sufficient to maintain structured dominance relationships. Using sound analysis and playback experiments with both natural and modified signals, we determined that males do not rely on encoded information about size or dominance status, but rather learn to recognize individual acoustic signatures produced by their rivals. Further, we show that behavioural responses to competitors' calls are modulated by relative position in the hierarchy: the highest ranking (alpha) males defend their harems from all opponents, whereas mid-ranking (beta) males respond differentially to familiar challengers based on the outcome of previous competitive interactions. Our findings demonstrate that social knowledge of rivals alone can regulate dominance relationships among competing males within large, spatially dynamic social groups, and illustrate the importance of combining descriptive and experimental methods when deciphering the biological relevance of animal signals.

    Animals exhibit a spectacular array of traits to attract mates. Understanding the evolutionary origins of sexual features and preferences is a fundamental problem in evolutionary biology, and the mechanisms remain highly controversial. In some species, females choose mates based on direct benefits conferred by the male to the female and her offspring. Thus, female preferences are thought to originate and coevolve with male traits. In contrast, sensory exploitation occurs when expression of a male trait takes advantage of preexisting sensory biases in females. Here, we document in Drosophila a previously unidentified example of sensory exploitation of males by other males through the use of the sex pheromone CH503. We use mass spectrometry, high-performance liquid chromatography, and behavioral analysis to demonstrate that an antiaphrodisiac produced by males of the melanogaster subgroup also is effective in distant Drosophila relatives that do not express the pheromone. We further show that species that produce the pheromone have become less sensitive to the compound, illustrating that sensory adaptation occurs after sensory exploitation. Our findings provide a mechanism for the origin of a sex pheromone and show that sensory exploitation changes male sexual behavior over evolutionary time. PMID:24516141

    The purpose of this study was to detect chromosomal aberrations and azoospermia factor (AZF) microdeletions in male patients with reproductive problems and to summarize related clinical features to provide reliable information for evaluating prenatal and preimplantation diagnoses. A large cohort of 5083 men with various phenotypes of male infertility was analyzed via G-banding karyotyping, and Origin 8.0 was used to analyze the prevalence of abnormalities. Additionally, patients with azoospermia, oligozoospermia, and oligoasthenozoospermia were analyzed using multiplex polymerase chain reaction to detect microdeletion in the AZF. We identified 387 patients with abnormal karyotypes, and the ratio was 7.61%. Among them were 175 patients with Klinefelter's syndrome, which was the most common numerical chromosomal abnormality and accounted for 45.22% of all chromosomal aberrations. The frequencies of increased satellites, balanced translocations, and Robertsonian translocations were 6.47, 7.00, and 3.62%, respectively. Multiplex polymerase chain reaction performed in 810 cases with azoospermia, oligozoospermia, and oligoasthenozoospermia found a ratio of AZF microdeletions of 4.94%. The finding suggests that chromosomal abnormalities and AZF deletion are main factors that result in male infertility. Detecting these common genetic variations is necessary in infertile men seeking assisted reproductive technology. PMID:24390997

    In order to establish a standard for sodium influx in erythrocytes for the black population, {sup 22}Na{sup +} uptake was measured in 29 normotensive black volunteers. Nineteen males and 10 females during the follicular phase of the menstrual cycle were studied. In the males, cell concentrations ranging from 0.64 to 2.0 X 10(9)/ml showed an influx of 0.42 to 1.34% of the total {sup 22}Na{sup +} added, and in the females, using the same erythrocyte concentrations, the {sup 22}Na{sup +} influx ranged from 0.37 to 1.1%; these differences were not significant. Intraassay variation of the {sup 22}Na{sup +} data was 4.8%. Interassay variations have been explained elsewhere. These data provided a range of observed values for {sup 22}Na{sup +} uptake in erythrocytes from a subpopulation of normotensive black males and females for comparison with hypertensive patients.

    X linked agammaglobulinemia (XLA) is the first described primary immunodeficiency and the most common form of agammaglobulinemia. It is characterized by susceptibility to recurrent infections, profound decrease of all immunoglobulin isotypes and very low level of B lymphocytes in peripheral blood. The disorder is caused by mutations in the Bruton's Tyrosine Kinase (BTK). Nine male patients suspected to have XLA from nine unrelated families were enrolled in this study. We performed sequencing of the BTK gene in all nine patients, and in the patients' relatives when possible. The XLA diagnosis was confirmed for six patients with six different mutations; we identified a novel mutation (c.1522G>A) and five known mutations. One third of nine unrelated patients do not have mutations in BTK and thus likely suffer from autosomal recessive agammaglobulinemia in the setting of consanguinity. Our results support that the autosomal recessive agammaglobulinemia can be more common in Algeria. PMID:26387629

    Gas chromatographic-electroantennographic detection (G3C-EAD) experiments showed that antennae of males and females of the goldeneyed lacewing, Chrysopa oculata Say (Co. = Chrysopa), consistently responded to four compounds extracted from the abdominal cuticle of males:nonanal, nonanol, nonanoic acid, and (1R*,2S*,5R*,8R*)-iridodial. These compounds were not detected from abdominal cuticle of females. Thoracic extracts of both sexes contained antennal-stimulatory 1-tridecene and EAD-inactive skatole. Chrysopa oculata adults were most sensitive to (1R,2S,5R,8R)-iridodial standard at an EAD-response threshold between 0.1 and 1 pg, which was 10-100 times lower than thresholds for nonanal and nonanoic acid, and up to 10,000 times lower than thresholds for other compounds tested. A similar EAD response pattern was also found in another Chrysopa sp. (Co. quadripunctata Burmeister). In field-trapping experiments, (1R,2S,5R,8R)-iridodial was the only male-specific compound that attracted Co. oculata males. Males also were weakly attracted to (1R,4aS,7S,7aR)-nepetalactol (an aphid sex pheromone component), probably due to the 5% (1R,2S,5R,8R)-iridodial present in the synthetic sample as an impurity. A herbivore-induced plant volatile, methyl salicylate, increased attraction of males to (1R,2S,5R,8R)-iridodial, whereas 1-tridecene was antagonistic. No females were caught in the entire study. Scanning electron micrographs revealed numerous male-specific, elliptical epidermal glands on the 3rd-8th abdominal sternites of Co. oculata, which are likely the pheromone glands. Another lacewing species, Chrysoperla rufilabris (Burmeister) (Cl. = Chrysoperla), did not produce male-specific volatiles or possess the type of gland presumed to produce pheromone in Co. oculata males, but (Z)-4-tridecene was identified as a major antennal-stimulatory compound from thoracic extracts of both sexes of Cl. rufilabris. Thus, (1R,2S,5R,8R)-iridodial (or its enantiomer) is now identified as a male-produced male aggregation pheromone for Co. oculata, the first pheromone identified for lacewings. PMID:15586679

    Abstract The primary aim was to compare postoperative radiographic outcomes between sexes among adolescent idiopathic scoliosis (AIS) patients. A total of 162 AIS patients (42 males and 120 females) undergoing pedicle screw instrumentation and posterior fusion were included. Coronal and sagittal curves and flexibilities were measured and calculated. The postoperative correction rate (CR), fulcrum bending correction index (FBCI), and Cincinnati correction index were evaluated to compare the surgical benefits between sexes. Males were older (16.79 vs 14.79 years, respectively; P?Males and females exhibited similar Lenke classification schemes (P?=?0.72), but had different Risser signs (P?males had greater postoperative curves (20.81° vs 16.83°, respectively; P?=?0.009), no obvious differences in the CRs were noted between males and females (FBCI: 145.20% vs 108.37%, respectively; P?=?0.92). Smaller preoperative lumbar lordosis was noted in males than in females (40.05° vs 45.72°, respectively; P?=?0.03), yet no statistically significant differences in the preoperative and postoperative sagittal curves were observed between the sexes. In conclusion, considering the preoperative flexibilities, the 2 sexes achieved comparable surgical benefits without sacrificing the sagittal balance. PMID:26469897

    Purpose Anemia could cause psychiatric symptoms such as cognitive function disorders and depression or could deteriorate an existing psychiatric condition when it is untreated. The objective of this study is to scrutinize the frequency of anemia in chronic psychiatric patients and the clinical and sociodemographic factors that could affect this frequency. Methods All inpatients in our clinic who satisfied the study criteria and received treatment between April 2014 and April 2015 were included in this cross-sectional study. Sociodemographic data for 378 patients included in the study and hemoglobin (Hb) and hematocrit values observed during their admission to the hospital were recorded in the forms. Male patients with an Hb level of <13 g/dL and nonpregnant female patients with an Hb level of <12 g/dL were considered as anemic. Findings Axis 1 diagnoses demonstrated that 172 patients had depressive disorder, 51 patients had bipolar disorder, 54 patients had psychotic disorder, 33 patients had conversion disorder, 19 patients had obsessive-compulsive disorder, 25 patients had generalized anxiety disorder, and 24 patients had other psychiatric conditions. It was also determined that 25.4% of the patients suffered from anemia. Thirty-five percent of females and 10% of males were considered as anemic. The frequency of anemia was the highest among psychotic disorder patients (35%), followed by generalized anxiety disorder patients (32%), and obsessive-compulsive disorder patients (26%). Anemia was diagnosed in 22% of depressive disorder patients, 25% of bipolar disorder patients, and 24% of conversion disorder patients. Results The prevalence of anemia among chronic psychiatry patients is more frequent than the general population. Thus, the study concluded that it would be beneficial to consider the physical symptoms and to conduct the required examinations to determine anemia among this patient group. PMID:26543367

    If a female mates with a male of a closely related species, her fitness is likely to decline. Consequently, females may develop behavioral mechanisms to avoid mating with heterospecific males. In some species, one such mechanism is for adult females to learn to discriminate against heterospecific males after exposure to such males. We have previously shown that adult, female Syrian hamsters (Mesocricetus auratus) learn to discriminate against male Turkish hamsters (Mesocricetus brandti) after exposure to a single heterospecific male during 8 days across a wire-mesh barrier. Here we repeated that experiment but this time we exposed female Turkish hamsters to a male Syrian hamster for 8 days and then measured sexual and aggressive behaviors towards that heterospecific male and towards a conspecific male. In contrast to female Syrian hamsters, female Turkish hamsters did not differ in their latency to go into lordosis or in any measure of aggression towards either type of male. Female Turkish hamsters spent less time in lordosis with the heterospecific male, but the percentage of trials in which females copulated with conspecific and heterospecific males did not differ. When comparing females from both species that had been exposed to a heterospecific male for 8days, female Syrian hamsters copulated less and were more aggressive towards the heterospecific male compared to the behavior of female Turkish hamsters. We discuss how this asymmetric response between females of the two species may be due to the much larger geographical range of Turkish hamsters compared to Syrian hamsters. PMID:22658324

  19. The puzzling attractiveness of male shame.

    Two studies examined the mechanisms underlying North American women's previously documented attraction to men displaying the nonverbal expression of shame (Tracy and Beall, 2011). In Study 1, American women at high-conception risk were found to be less attracted to men displaying shame compared to women at low-conception risk, suggesting that male shame displays indicate poor genetic fitness. In Study 2, Indian women were found to be less attracted to men displaying shame than American women, suggesting that American women's tendency to find shame-displaying men attractive is likely due to local socio-cultural factors rather than to universal genetically encoded predispositions. Together, findings suggest that the attractiveness of male shame displays, previously documented in several North American samples, is best explained by cultural rather than biological factors.

  20. Investigation and Management of Male Infertility

    Infertility is rarely due only to the male or female partner. Usually each partner's fertility is in some way diminished. Male infertility may be related to deficiencies in spermatogenesis or sperm transport. Accurate diagnosis can be achieved only by a careful evaluation including precise semen analyses and, where indicated, gonadotropin and other assays. Treatment may be specific for physical or endocrine deficits, but is often empirical. Factors other than the sperm count, such as emission of sperm mainly at the beginning of ejaculation, low seminal volume with good quality sperm, excessive seminal viscosity, pyospermia, and idiopathic oligospermia, may be responsible for infertility. These may respond to simple measures. Understanding and empathy for the infertile couple is of the utmost importance. PMID:21283272
