    The male germinal cells constitute a heterogeneous cell population including pre-meiotic proliferating cells (spermatogonia) and meiotic cells and post meiotic cells in differentiation (spermatocytes and spermatids). We study the involvement in vivo of the p53 protein in the death of these cells with the help of two models, (1) a transgenic model of infertility, MTp53, in which the p53 is over expressed in the differentiated cells and induced their death, (2) the response of these cells to gamma irradiation, where only the spermatogonia die by apoptosis dependent of p53. We showed that the caspases (cysteine-aspartic proteases) are involved in the terminal differentiation of normal germinal cells. But in the MTp53 model, the p53 induces the death of differentiated cells via the activation of calpains and not of caspases. We studied the response of spermatogonia, to gamma irradiation by a transcriptomic approach, by DNA chips and semi-quantitative RT-PCR. we showed that the puma and dr5 genes are induced by the p53 after irradiation. more, the study of mice invalidated for trail ( the dr5 ligand) or for puma, allowed to demonstrate that the two effectors are essential to the activation of intrinsic and extrinsic ways of apoptosis.

    Cellulitis is an acute infection of the dermal and subcutaneous layers of the skin, often occurring after a local skin trauma. It is a common diagnosis in both inpatient and outpatient dermatology, as well as in the primary care setting. Cellulitis classically presents with erythema, swelling, warmth, and tenderness over the affected area. There are many other dermatologic diseases, which can present with similar findings, highlighting the need to consider a broad differential diagnosis. Some of the most common mimics of cellulitis include venous stasis dermatitis, contact dermatitis, deep vein thrombosis, and panniculitis. History, local characteristics of the affected area, systemic signs, laboratory tests, and, in some cases, skin biopsy can be helpful in confirming the correct diagnosis. Most patients can be treated as an outpatient with oral antibiotics, with dicloxacillin or cephalexin being the oral therapy of choice when methicillin-resistant Staphylococcus aureus is not a concern.

    The Authors report a case of eosinophilic cellulitis (Wells' syndrome). The patient was a 61 year old woman, diabetic, with a cardio-respiratory insufficiency and a maniaco-depressive psycosis. She presented, on the upper arms and trunk, a cutaneous eruption of erythematous-urticarial plaques, that histopathologically were characterized by a dermic leukocyte population, with a prevalence of eosinophils, distributed in the perivascular site. Laboratory tests revealed eosinophilia and circulating immune complexes. The etiopathogenesis of the disease is discussed as is the possible role of immune complexes in eosinophilic cellulitis.

    Full Text Available Preseptal cellulitis (PC is defined as an inflammation of the eyelid and surrounding skin, whereas orbital cellulitis (OC is an inflammation of the posterior septum of the eyelid affecting the orbit and its contents. Periorbital tissues may become infected as a result of trauma (including insect bites or primary bacteremia. Orbital cellulitis generally occurs as a complication of sinusitis. The most commonly isolated organisms are Staphylococcus aureus, Streptococcus pneumoniae, S. epidermidis, Haempphilus influenzae, Moraxella catarrhalis and S. pyogenes. The method for the diagnosis of OS and PS is computed tomography. Using effective antibiotics is a mainstay for the treatment of PC and OC. There is an agreement that surgical drainage should be performed in cases of complete ophthalmoplegia or significant visual impairment or large abscesses formation. This infections are also at a greater risk of acute visual loss, cavernous sinus thrombosis, meningitis, cerebritis, endophthalmitis, and brain abscess in children. Early diagnosis and appropriate treatment are crucial to control the infection. Diagnosis, treatment, management and complications of PC and OC are summarized in this manuscript.

    Full Text Available Background: odontogenic facial cellulitis is an acute inflammatory process manifested in very different ways, with a variable scale in clinical presentation ranging from harmless well defined processes, to diffuse and progressive that may develop complications leading the patient to a critical condition, even risking their lives. Objective: To characterize the behavior of odontogenic facial cellulitis. Methods: A descriptive case series study was conducted at the dental clinic of Aguada de Pasajeros, Cienfuegos, from September 2010 to March 2011. It included 56 patients who met the inclusion criteria. Variables analyzed included: sex, age, teeth and regions affected, causes of cellulite and prescribed treatment. Results: no sex predilection was observed, lower molars and submandibular anatomical region were the most affected (50% and 30 4% respectively being tooth decay the main cause for this condition (51, 7%. The opening access was not performed to all the patients in the emergency service. The causal tooth extraction was not commonly done early, according to the prescribed antibiotic group. Thermotherapy with warm fomentation and saline mouthwash was the most prescribed and the most widely used group of antibiotics was the penicillin. Conclusions: dental caries were the major cause of odontogenic cellulite. There are still difficulties with the implementation of opening access.

    Full Text Available Pediatric preseptal and orbital cellulitis are infectious disorders that result in periorbital inflammation. Preseptal cellulitis is often associated with breaches in the skin barrier whereas orbital cellulitis is commonly associated with paranasal sinusitis. Orbital cellulitis may be associated with subperiosteal abscess. It is important to distinguish between preseptal from orbital cellulitis. Clinical examination and diagnostic imaging are useful in determining appropriate management. Patients are usually treated with broad spectrum antibiotics and surgery when indicated.

    Full Text Available Bacteria of the genus Salmonella are highly adapted for the growth in both humans and animals and cause a wide spectrum of disease. The growth of Serotypes S. typhi and S. paratyphi is restricted to human hosts, in whom these organisms cause enteric (typhoid fever. The remaining Serotypes (non typhoidal Salmonella or NTS can colonize the gastrointestinal tracts of the broad range of animals, including mammals, reptiles, birds and insects. The usual clinical presentation of non-typhoidal salmonellae (NTS infection is self limited gastroenteritis; however bacteremia and focal extra intestinal infection may occur. However salmonella localization to the skin presenting as cutaneous ulceration is regarded as a rare event. Rates of morbidity and mortality associated with NTS are highest among the elderly, infants, and immunocompromised individuals, including those with hemoglobinopathies, HIV infection, or infections that cause blockade of the reticuloendothelial system. We isolated S.infantis in 50 years old man with left leg cellulitis. The serotype was confirmed at Central Research Institute, Kasauli.

    2016-10-01

    Dacryocystitis-related orbital cellulitis is a relatively rare condition, and large case series of this clinical entity have been reported. This study was undertaken to identify a larger cohort of patients with this ailment, with the intent of defining its clinical and microbiologic features. Case logs from four institutions were reviewed to identify patients that suffered from dacryocystitis-related orbital cellulitis. A retrospective chart review was then performed to identify clinical features, management strategies, microbiologic features, and outcomes. A dedicated statistical software package was utilized to identify correlations between these variables. 13 patients (7 females, 6 males; mean age = 57.2 years, range = 7-89 years) were identified. One patient carried a diagnosis of immunosuppressive disease. All patients underwent emergent surgical drainage and received intravenous antibiotics. Primary acquired nasolacrimal duct obstruction was found to be the underlying etiology in nine cases (69.2%), whereas four patients suffered from specific causes of their obstructions. An average of 1.07 organisms/patient (standard deviation = 0.49 organisms/patient) were recovered from microbiologic cultures, and Gram-positive bacteria represented the majority of cultured organisms. All patients experienced either stable or improved vision upon discharge. The relationships between a specific etiology and the possibility of vision loss or the number of organisms cultured, between the number of organisms cultured and vision loss, and immunosuppression and vision loss or the number of organisms cultured were all not statistically significant (p > 0.05). Dacryocystitis-related orbital cellulitis most commonly occurs in adult patients who do not carry immunosuppressive diagnoses and suffer from primary obstructions. Multiple microbiologic species may cause this problem, although Gram-positive organisms are most common. With appropriate management, stable or improved vision

    Full Text Available OBJECTIVE: The flood after a typhoon may lead to increase in patients with cellulitis of lower limbs. However, the microbiological features of these cases are rarely reported. We conducted a study of patients with lower extremity cellulitis after a typhoon followed in southern Taiwan to study the risk factors of cellulitis and the bacteriological features of the patients. METHODS: We reviewed all the medical records of cellulitis at emergency departments of two teaching hospitals in southern Taiwan 30 days before and after the landing of Typhoon Morakot and collected data on the demographic and bacteriological characteristics. In addition, we evaluated the relationship between the daily number of patients and the rainfall in the Tainan area. RESULTS: The number of cellulitis patients increased from 183 to 344 during the 30-day period after the typhoon. The number peaked in the third and fourth days and lasted for 3 weeks. The proportion of patients with water immersion of the affected limb was higher after the typhoon (6% vs. 37%, odds ratio [OR]: 9.0, 95% Confidence interval [CI]: 4.7-17.2. We found cultures from the infected limbs with immersion had more polymicrobial (73% vs. 26%, OR: 7.8, 95% CI: 3.2-19.2 and Gram-negative bacilli infection (86% vs. 34%, OR: 11.8, 95% CI: 4.1-34.5. CONCLUSIONS: Flood arose from Typhoon Morakot caused increases in cellulitis patients, which lasted for 3 weeks. Antibiotic treatment that were effective to both Gram-positive cocci and Gram-negative bacilli are recommended for patients with limbs emerged in the water.

    Full Text Available Avian cellulitis is an inflammatory process in the subcutaneous tissue, mainly located in the abdomen and thighs. This problem is commonly observed in poultry at slaughter and it is considered one of the major causes of condemnation of carcasses in Brazil. The aim of this study was to perform the microbial isolation of lesions of avian cellulitis from a processing plant located in the State of Goiás in order to analyze antimicrobial resistance by antibiogram test and to detect resistance genes by polymerase chain reaction. A total of 25 samples of avian cellulitis lesions were analyzed, from which 30 bacterial strains were isolated. There were eleven (44% strains of Escherichia coli, nine (36% strains of Staphylococcus epidermidis, seven (28% strains of Proteus mirabilis and three (12% strains of Manheimiahaemolytica. The antibiogram test showed that all strains were resistant to at least one antimicrobial. The gene of antimicrobial resistance tetB was detected in E. coli, S. epidermidis and P. mirabilis strains, and was the most frequently observed gene. The gene of antimicrobial resistance Sul1 was detected in all bacterial species, while tetA was found in E. coli and S. epidermidis strains, SHV in E. coli strains, S. epidermidis and P. mirabilis,and cat1 in one P. mirabilis strain. The results suggest a potential public health hazard due to the ability of these microorganisms to transmit antimicrobial resistancegenes to other microorganisms present in the intestinal tract of humans and animals, which may affect clinical-medical usage of these drugs.

    Objective To evaluate the prevalence and associated factors involved in cellulitis with lymphangitis among a group of Korean patients who were being treated for lymphedema. We present our epidemiologic research and we also report a systematic review of these types of cases. Methods This was a retrospective medical record study among 1,246 patients diagnosed with lymphedema. The study was carried out between January 2006 and December 2012 at the Kosin University Gospel Hospital and Seoul National University Bundang Hospital. Cases were examined for onset time, affected site, seasonal trend, and recurrence pattern of lymphedema, lymphangitis, and cellulitis. We also evaluated the history of blood-cell culture and antibiotic use. Results Ninety-nine lymphedema patients experienced complications such as cellulitis with accompanying lymphangitis. Forty-nine patients had more than two recurrences of cellulitis with lymphangitis. The incidence and recurrence of cellulitis with lymphangitis were significantly higher in the patients with lower-extremity lymphedema. There was a significant trend toward higher cellulitis prevalence in the lower-extremity lymphedema group according to the time of lymphedema onset. Among the cellulitis with lymphangitis cases, 62 cases were diagnosed through blood-cell culture; 8 of these 62 cultures were positive for β-hemolytic streptococci. Conclusion The prevalence rate of cellulitis with lymphangitis in patients with lymphedema was 7.95%, and the prevalence of recurrent episodes was 3.93%. Especially, there was high risk of cellulitis with lymphangitis after occurrence of lower-extremity lymphedema with passage of time. Lymphedema patients should be fully briefed about the associated risks of cellulitis before treatment, and physicians should be prepared to provide appropriate preventive education. PMID:27152284

    Erosive pustular dermatosis (EPD) of the leg is an unusual form of amicrobial pustulosis, which typically affects elderly patients with chronic venous insufficiency. We report a patient who presented with painful erythema, crusted erosions and pustules on her right lower leg. Histology showed a dermal infiltration made up predominantly of neutrophils. Bacteria were isolated from the lesions. The condition was initially diagnosed as cellulitis, but antibiotic treatment was unsuccessful. After the correct diagnosis was made, complete resolution was obtained with betamethasone 0.05%. PMID:25476720

    We report a case of acute neck cellulitis and mediastinitis complicating a continuous interscalene brachial plexus block. A 61-yr-old man was scheduled for an elective arthroscopic right shoulder rotator cuff repair. A continuous interscalene block was done preoperatively and 20 mL of 0.5% bupivacaine and 20 mL of 2% mepivacaine were injected through the catheter. Postoperative analgesia was provided by a continuous infusion of bupivacaine, 0.25% at 5 mL/h for 39 h using a 240-mL elastomeric disposable pump. The day after surgery, the patient complained of neck pain. The analgesic block was not fully effective. He was discharged home. Three days later, the patient was readmitted with neck edema and erythema, fever and fatigue. Neck ultrasonography and computed tomographic scan revealed an abscess of the interscalene and sternocleidomastiod muscles and cellulitis, as well as acute mediastinitis. Two blood cultures and surgical samples were positive for Staphylococcus aureus. The infection was treated with surgery, the site was surgically debrided, and a 2-mo course of vancomycin, imipenem, and oxacilline. The technique of drawing local anesthetic from the bottle and filling the elastomeric pump was the most likely cause of infection. This case emphasizes the importance of strict aseptic conditions during puncture, catheter insertion, and management of the local anesthetic infusate. PMID:18806062

    2008-12-01

    Full Text Available The aim of this study was to assess the use of magnetic resonance as a new method for evaluating the manual lymphatic drainage technique in treating cellulitis. Cellulitis is one of the main esthetic problems that lead women toward seeking guidance and specific treatments. There are various therapeutic approaches, owing to the multi-factorial nature of its pathogen, although the effectiveness of most of these has not been definitively proven, given that the assessment methods used are mostly subjective or do not provide enough information on subcutaneous tissue. The introduction of magnetic resonance as a means of assessing a lymphatic drainage technique in cellulitis treatment makes the evaluation more accurate, since it enables a detailed study of subcutaneous architecture.Objetivo: Este estudo objetiva avaliar o uso da Ressonância Magnética como uma nova técnica de avaliação de uma técnica de drenagem linfática no tratamento do Fibro Edema Gelóide (FEG. O FEG, popularmente conhecido como "celulite" é um dos principais problemas de estética corporal que leva as mulheres a procurar orientações e tratamentos específicos. Devido à natureza multifatorial da sua patogenia, existem várias abordagens terapêuticas, mas a maioria desses não tem sua eficácia comprovada de maneira acurada, pois os métodos de avaliação utilizados, em sua maioria, são subjetivos ou não provêem informações suficientes para o estudo do tecido subcutâneo. A introdução da ressonância magnética como meio de avaliação de uma técnica de drenagem linfática no tratamento do FEG a torna mais acurada, uma vez que a mesma possibilita o estudo detalhado da arquitetura do subcutâneo.

  1. Acetaminophen-induced cellulitis-like fixed drug eruption

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available Acetaminophen is a widely used analgesic drug. Its adverse reactions are rare but severe. An 89-year-old man developed an indurated edematous and erythematous plaque on his left arm 1 day after acetaminophen ingestion. Cellulitis was suspected and antibiotictherapy was started but there was no improvement of the rash; there was a spectacular extension of the lesion with occurrence of flaccid vesicles and blisters in the affected sites. The diagnosis of generalized-bullous-fixed drug eruption induced by acetaminophen was considered especially with a reported history of a previous milder reaction occurring in the same site. Acetaminophen was withdrawn and the rash improved significantly. According to the Naranjo probability scale, the eruption experienced by the patient was probably due to acetaminophen. Clinicians should be aware of the ability of acetaminophen to induce fixed drug eruption that may clinically take several aspects and may be misdiagnosed.

    Risk factors for recurrent cellulitis were assessed in a case-control study including 398 patients receiving prophylactic treatment with benzathine penicillin and 8,005 controls derived from a national population-based health survey. In the multivariate analysis, psoriasis [odds ratio (OR) 3.69], other chronic dermatoses (OR 4.14), diabetes (OR 1.65), increasing body mass index (OR 1.17), increasing age (OR 1.06) and history of previous tonsillectomy (OR 6.82) were independently associated with recurrent cellulitis. Forty percent of the patients reported a cellulitis recurrence, despite ongoing benzathine penicillin prophylaxis. The role of previous tonsillectomy in recurrent cellulitis needs further evaluation.

    Full Text Available Background: Pegylated interferon and ribavirin are currently one of the accepted treatment for chronic Hepatitis C. Dermatologic complications of interferon have been reported, but to date a few cases of bacterial cellulitis; a rare and severe complication, have been published. Cellulitis is a common infectious process affecting the skin and subcutaneous tissues which results in significant morbidity and holds considerable healthcare costs.Cases Report: Herein, we report a case of chronic hepatitis C genotype 1a who was on medication since 8 weeks prior to developing leg cellulitis, an uncommon pegylated interferon injection site. Considering no other possible risk factors were found to be in favor of bacterial cellulitis, our case is unique in its kind. Some reports reveal necrotizing vasculitis as basis for cutaneous lesions, which could be due to the high concentrations of drug at the injection site, a toxic effect of the diluents, or an immunological reaction.Conclusion: According to the latter mechanism patients could develop bacterial cellulitis in their different organs. Conclusively, we propose the hypothesis of a possible association between cellulitis to occur at any site as the complication of pegylated interferon Alfa 2b and would highlight the role of a careful skin examination that could be an asset in preventing local skin infections.

    Räßler, F; Lukács, J; Elsner, P

    2016-09-01

    Eosinophilic cellulitis (Wells syndrome) is a rare inflammatory skin disease defined by erythematous, tender, sometimes urticarial plaques, possibly with vesicles and bullae, and granulomatous eosinophilic infiltrates in the dermis. Usually the disease has a benign course with spontaneous remission within a few weeks. Nevertheless, recurrences are quite frequent and may occur for several years. The objective of this study was to review the so far reported treatment options for Wells syndrome in a systematic manner. This systematic review is based on a search on Medline, Embase and Cochrane Central Register for English and German articles from 1970 to 2015. Advices on the treatment of Wells syndrome are limited predominately to case reports or to small case series. There are no randomized controlled trials, and control groups are missing. A variety of treatment options for Wells syndrome were reported including topical and systemic corticosteroids, antihistamines, cyclosporine, dapsone, azathioprine, griseofulvin, doxycycline, minocycline, antimalarial medications, oral tacrolimus/topical tacrolimus, sulfasalazine, interferon alpha and gamma, TNF alpha inhibitors, colchicine and PUVA therapy. As well-designed, randomized controlled trials are missing, no guidelines for the treatment of this disease can be given. Due to the small number of patients and the frequent misdiagnosis of this clinical entity, the aim of this systematic overview is to call attention to this rare condition and to help clinicians to diagnose and treat Wells syndrome effectively. Due to the good prognosis and tendency to resolve, systemic treatment should be limited to cases resistant to local therapy or with widespread lesions. PMID:27357601

    Bacteriological diagnosis is rarely achieved in acute cellulitis. Beta-haemolytic streptococci and Staphylococcus aureus are considered the main pathogens. The role of the latter is, however, unclear in cases of non-suppurative cellulitis. We conducted a serological study to investigate the bacterial aetiology of acute non-necrotising cellulitis. Anti-streptolysin O (ASO), anti-deoxyribonuclease B (ADN) and anti-staphylolysin (ASTA) titres were measured from acute and convalescent phase sera of 77 patients hospitalised because of acute bacterial non-necrotising cellulitis and from the serum samples of 89 control subjects matched for age and sex. Antibiotic treatment decisions were also reviewed. Streptococcal serology was positive in 53 (69%) of the 77 cases. Furthermore, ten cases without serological evidence of streptococcal infection were successfully treated with penicillin. Positive ASO and ADN titres were detected in ten (11%) and three (3%) of the 89 controls, respectively, and ASTA was elevated in three patients and 11 controls. Our findings suggest that acute non-necrotising cellulitis without pus formation is mostly of streptococcal origin and that penicillin can be used as the first-line therapy for most patients.

    Full Text Available Introduction. Infectious diseases caused by Streptococcus pyogenes, a member of the group A Streptococci (GAS are among the most common life threatening ones. Patients with GAS infections have a poor survival rate. Cellulitis is a severe invasive GAS infection and the most common clinical presentation of the disease associated with more deaths than it can be seen in other GAS infections. According to the literature data, most cases of GAS toxic shock syndrome are developed in the puerperium. However, there are two main problems with GAS infection in early puerperium and this case report is aimed at reminding on them. The first problem is an absence of awareness that it can be postpartal invasive GAS infection before the microbiology laboratory confirms it, and the second one is that we have little knowledge about GAS infection, in general. Case report. A 32- year-old healthy woman, gravida 1, para 1, was hospitalized three days after vaginal delivery with a 38-hour history of fever, pain in the left leg (under the knee, and head injury after short period of conscious lost. Clinical picture of GAS infection was cellulites. Group A Streptoccocus pyogenes was isolated in vaginal culture. Rapid antibiotic and supportive treatment stopped development of streptococcal toxic shock syndrome (STSS and potential multiorganic failure. Signs and symptoms of the infection lasted 25 days, and complete recovery of the patient almost 50 days. Conclusion. In all women in childbed with a history of fever early after delivery, vaginal and cervical culture specimens should be taken as soon as possible. Early recognition of GAS infection in early puerperium and prompt initiation of antimicrobial drug and supportive therapy can prevent development of STSS and lethal outcome.

  11. Delayed breast cellulitis: An evolving complication of breast conservation

    International Nuclear Information System (INIS)

    Purpose: Delayed breast cellulitis (DBC) is characterized by the late onset of breast erythema, edema, tenderness, and warmth. This retrospective study analyzes the risk factors and clinical course of DBC. Methods and Materials: From 1985 through 2004, 580 sequential women with 601 stage T0-2N0-1 breast cancers underwent breast conserving therapy. Cases of DBC were identified according to accepted clinical criteria: diffuse breast erythema, edema, tenderness, and warmth occurring >3 months after definitive surgery and >3 weeks after radiotherapy. Potential risk factors analyzed included patient comorbidity, operative technique, acute complications, and details of adjunctive therapy. Response to treatment and long-term outcome were analyzed to characterize the natural course of this syndrome. Results: Of the 601 cases, 16%, 52%, and 32% were Stage 0, I, and II, respectively. The overall incidence of DBC was 8% (50/601). Obesity, ecchymoses, T stage, the presence and aspiration of a breast hematoma/seroma, removal of >5 axillary lymph nodes, and arm lymphedema were significantly associated with DBC. The median time to onset of DBC from the date of definitive surgery was 226 days. Ninety-two percent of DBC patients were empirically treated with antibiotics. Fourteen percent required more invasive intervention. Twenty-two percent had recurrent episodes of DBC. Ultimately, 2 patients (4%) underwent mastectomy for intractable breast pain related to DBC. Conclusion: Although multifactorial, we believe DBC is primarily related to a bacterial infection in the setting of impaired lymphatic drainage and may appear months after completion of radiotherapy. Invasive testing before a trial of antibiotics is generally not recommended

    Acute non-necrotizing cellulitis is a skin infection with a tendency to recur. Both general and local risk factors for erysipelas or cellulitis have been recognized in previous studies using hospitalized controls. The aim of this study was to identify risk factors for cellulitis using controls recruited from the general population. We also compared patients with a history of previous cellulitis with those suffering a single episode, with regard to the risk factors: length of stay in hospital, duration of fever, and inflammatory response as measured by C-reactive protein (CRP) level and leukocyte count. Ninety hospitalized cellulitis patients and 90 population controls matched for age and sex were interviewed and clinically examined during the period April 2004 to March 2005. In multivariate analysis, chronic oedema of the extremity, disruption of the cutaneous barrier and obesity were independently associated with acute cellulitis. Forty-four (49%) patients had a positive history (PH) of at least one cellulitis episode before entering the study. Obesity and previous ipsilateral surgical procedure were statistically significantly more common in PH patients, whereas a recent (<1 month) traumatic wound was more common in patients with a negative history (NH) of cellulitis. PH patients had longer duration of fever and hospital stay, and their CRP and leukocyte values more often peaked at a high level than those of NH patients. Oedema, broken skin and obesity are risk factors for acute cellulitis. The inflammatory response as indicated by CRP level and leukocyte count is statistically significantly more severe in PH than NH patients. PMID:19694769

    Full Text Available Context: Preseptal cellulitis is the commonest orbital disease which frequently needs to be differentiated from orbital cellulitis. Prompt diagnosis and treatment with appropriate antibiotics can prevent vision loss and life-threatening complications of orbital cellulitis. Aims: To describe the clinical profile of cases with preseptal and orbital cellulitis admitted to a tertiary care hospital during a period of nine years. The causative organisms and the clinical outcome were analyzed. Settings and Design : Retrospective descriptive case study done in a tertiary care hospital in South India. Material and Methods: The in-patient records of patients with preseptal and orbital cellulitis were reviewed from 1998 to 2006. The factors reviewed included ocular findings aiding in the distinction of the two clinical conditions, the duration of symptoms, the duration of hospital stay, microbiological culture report of pus or wound swab, blood culture, drugs used for treatment, the response to therapy and complications. Statistical Analysis Used: Descriptive analysis. Results: One hundred and ten cases, 77 patients with preseptal cellulitis and 33 patients with orbital cellulitis were reviewed. Five percent of children and 21% of adults presented with cutaneous anthrax contributing to preseptal cellulitis. Thirty-nine percent cases with orbital cellulitis were caused by methicillin-resistant Staphylococcus aureus (MRSA. Conclusions: This study has helped in identifying organisms which cause orbital infections, especially community-acquired MRSA. It indicates the need for modifying our empirical antimicrobial therapy, especially in orbital cellulitis.

  20. Facing the danger zone: the use of ultrasound to distinguish cellulitis from abscess in facial infections.

    Science.gov (United States)

    Lewis, Dywanda L; Butts, Christine J; Moreno-Walton, Lisa

    2014-01-01

    Physical exam alone is often insufficient to determine whether or not cellulitis is accompanied by an abscess. Bedside ultrasound can be a valuable tool in ruling out suspected abscess by allowing direct visualization of a fluid collection. The proximity of the infection to adjacent structures can also be determined, thus aiding clinical decision making. Patients with cellulitis near the eye and nose are of particular concern due to the adjacent facial structures and the anatomy of the venous drainage. Accurately determining the presence or absence of an associated abscess in these patients is a crucial step in treatment planning. The purpose of this report is to (1) emphasize the benefits of bedside ultrasound when used in conjunction with the physical exam to rule out abscess; (2) demonstrate the utility of bedside ultrasound in planning a treatment strategy for soft tissue infection; (3) depict an instance where ultrasound detected an abscess when computed tomography (CT) scan did not.

    2001-06-01

    Eight African hedgehogs (Atelerix albiventris) were presented with unilateral proptosis. Six animals presented specifically for an ocular problem, whereas two had concurrent neurologic disease. Enucleation and light microscopic examination of tissues was performed in five animals, and euthanasia followed by complete postmortem examination was performed in three animals. Histopathologic findings in all hedgehogs included orbital cellulitis, panophthalmitis, and corneal ulceration, with perforation in seven of eight eyes. The etiology of the orbital cellulitis was not determined, but it appeared to precede proptosis. Orbits in hedgehogs are shallow and the palpebral fissures are large, which may predispose them to proptosis, similar to brachycephalic dogs. This clinical presentation was seen in 15% (8/54) of African hedgehogs presented to the Western College of Veterinary Medicine over a 2-yr period from January 1995 to December 1996 and warrants further investigation.

    Full Text Available Abstract Background Cellulitis caused by Mycobacterium avium-intracellulare has rarely been described. Mycobacterium avium-intracellulare is a rare cause of septic arthritis after intra-articular injection, though the causative role of injection is difficult to ascertain in such cases. Case presentation A 57-year-old with rheumatoid arthritis treated with prednisone and azathioprine developed bilateral painful degenerative shoulder arthritis. After corticosteroid injections into both acromioclavicular joints, he developed bilateral cellulitis centered over the injection sites. Skin biopsy showed non-caseating granulomas, and culture grew Mycobacterium avium-intracellulare. Joint aspiration also revealed Mycobacterium avium-intracellulare infection. Conclusion Although rare, skin and joint infections caused by Mycobacterium avium-intracellulare should be considered in any immunocompromised host, particularly after intra-articular injection. Stains for acid-fast bacilli may be negative in pathologic samples even in the presence of infection; cultures of tissue specimens should always be obtained.

  6. A case of dissecting cellulitis and a review of the literature.

    Scheinfeld, Noah S

    2003-02-01

    Dissecting cellulitis (also called perifolliculitis capitis abscedens et suffodiens) manifests with perifollicular pustules, nodules, abscesses and sinuses that evolve into scarring alopecia. It predominantly occurs in African American men between 20-40 years of age, but can occasionally affect other races and women too. Associated musculoskeletal findings are sometimes reported. When it occurs with acne conglobata, hidradenitis suppurativa, and pilonidal cysts, the syndrome is referred to as the follicular occlusion triad or tetrad. Its course is chronic and relapsing, and treatment is often difficult. Medical therapies include isotretinoin, antibiotics, and prednisone. Destructive therapies include X-ray therapy, surgical excision, and skin grafting. Laser epilation of hair follicles is a promising new therapy for dissecting cellulitis. PMID:12639466

  7. Facing the Danger Zone: The Use of Ultrasound to Distinguish Cellulitis from Abscess in Facial Infections

    2014-01-01

    Full Text Available Physical exam alone is often insufficient to determine whether or not cellulitis is accompanied by an abscess. Bedside ultrasound can be a valuable tool in ruling out suspected abscess by allowing direct visualization of a fluid collection. The proximity of the infection to adjacent structures can also be determined, thus aiding clinical decision making. Patients with cellulitis near the eye and nose are of particular concern due to the adjacent facial structures and the anatomy of the venous drainage. Accurately determining the presence or absence of an associated abscess in these patients is a crucial step in treatment planning. The purpose of this report is to (1 emphasize the benefits of bedside ultrasound when used in conjunction with the physical exam to rule out abscess; (2 demonstrate the utility of bedside ultrasound in planning a treatment strategy for soft tissue infection; (3 depict an instance where ultrasound detected an abscess when computed tomography (CT scan did not.

  8. Radionuclide imaging in early detection of childhood osteomyelitis and its differentiation from cellulitis and bone infarction

    International Nuclear Information System (INIS)

    In children, radionuclide skeletal imaging with sup(99m)Tc-phosphate compounds is significantly more sensitive than roentgenographic studies in the early detection of osteomyelitis and septic arthritis. The scintigraphic patterns are usually characteristic. Cellulitis and some cases of early infarction are easily differentiated from osteomyelitis. However, some cases of infarction are indistinguishable from osteomyelitis on sup(99m)Tc-phosphate scan. In these cases 67Ga-citrate may prove helpful

    2015-01-01

    Full Text Available Cellulitis in the setting of lymphedema is an uncommon but clinically important presentation to the emergency department. Stagnant lymph is an ideal medium for bacterial growth and progression can be rapid due to decreased ability to fight infection in the affected area. Infections are commonly caused by gram-positive cocci, though blood cultures are often negative. Treatment should be aimed at rapid initiation of antibiotics targeting these species. There may be a role for antibiotic prophylaxis in recurrent cases.

    A working Border collie suffered a puncture wound to the metacarpal pad. No fractures or luxations were identified at initial presentation. Treatment was instigated with various antibacterials for a period of months. At subsequent visits, the dog's condition progressed with development of metacarpophalangeal joint luxation and phalangeal fractures secondary to cellulitis and chronic osteomyelitis. Amputation was curative. Prompt treatment of the acute condition with debridement and drainage may have prevented osteomyelitis becoming established in the first instance. PMID:15266860

    2015-05-01

    Infratemporal fossa cellulitis is rare and mostly occurs because of sinusitis and dental procedures. Furthermore, cellulitis caused by iatrogenic foreign bodies is very rare. A 28-year-old woman who had previously undergone cosmetic bimaxillary operation visited our hospital complaining of left facial swelling, oppressive pain, and nasal obstruction since 2 years. She had been attending another clinic, but despite having additional procedures and taking medications, her symptoms persisted. A subsequent operation was performed, during which we found a remnant surgical gauze from the previous operation, which was decomposed and trapped around the necrotic soft tissue and had eroded the bony structure around the pterygoid fossa. The material was successfully removed by endoscopic surgery, and the necrotic tissue was debrided. After the operation, all symptoms disappeared, and the patient was discharged without sequelae. During any procedure, surgeons must meticulously check for remnant material. Additionally, physicians must carefully note patient history and perform a physical examination, even in patients without serious symptoms. We report a case of advanced infratemporal fossa cellulitis due to remnant gauze material during a previous operation that was undetected. PMID:25950522

    The objective of this work was to analyze the predisposing factors, diagnostic and therapeutic aspects of cervico-facial cellulitis on pregnancies and to determine maternal-fetal prognosis. We conducted a longitudinal observational descriptive study from January 2011 to March 2013 including records from pregnant women with cervicofacial cellulitis treated at the Oto-Rhino-Laryngology (ORL) and cervico-facial surgery department at Gabriel Touré Hospital in Bamako. Ten women met our inclusion criteria. The median age was 23 years. The entry way was dental in all cases. Three women had taken antibiotics and 3 others antibiotics associated with non steroidal anti-inflammatory. The medico-surgical treatment had permitted to cure 8 cases. Two cases of death were recorded and 4 cases of stillbirths. The cervico-facial cellulitis during pregnancy is a serious pathology that can be life-threatening to the mother and or child. Prevention is based on the control of dental status and informing women about the importance of dental hygiene. PMID:25304000

    Full Text Available Abstract Background Methicillin-resistant Staphylococcus aureus is a serious cause of morbidity and mortality in hospital environment, but also, lately, in the community. This case report is, to our knowledge, the first detailed description of a community-associated methicillin-resistant S. aureus ST80 orbital cellulitis in a previously healthy neonate. Possible predisposing factors of microbial acquisition and treatment selection are also discussed. Case presentation A 28-day-old Caucasian boy was referred to our hospital with the diagnosis of right orbital cellulitis. His symptoms included right eye proptosis, periocular edema and redness. Empirical therapy of intravenous daptomycin, rifampin and ceftriaxone was initiated. The culture of pus yielded a methicillin-resistant S. aureus isolate and the molecular analysis revealed that it was a Panton-Valentine leukocidine-positive ST80 strain. The combination antimicrobial therapy was continued for 42days and the infection was successfully controlled. Conclusions Clinicians should be aware that young infants, even without any predisposing condition, are susceptible to orbital cellulitis caused by community-associated methicillin-resistant S. aureus. Prompt initiation of the appropriate empirical therapy, according to the local epidemiology, should successfully address the infection, preventing ocular and systemic complications.

    Full Text Available A 34-year-old male with diabetes presented to the emergency department with four days of progressively worsening redness, swelling and pain to his left buttock. The patient denied fevers, chills, rectal pain or purulent drainage from his rectum. His initial vital signs were heart rate of 82; blood pressure of 146/92; and temperature of 98.2°F. The left buttock had a poorly circumscribed area of induration; however, there was no fluctuance or crepitace. Rectal exam was unremarkable. Because the patient’s buttock pain was disproportionate to his exam findings, a point-of-care ultrasound was performed to determine if a more extensive process was present. The ultrasound demonstrated cobblestoning, fascial thickening with edema, and a large 4.5cm fluid collection extending and adjacent to the rectum.

    Full Text Available Objectives: Ambient air pollution, as many publications indicate, may have associations with skin condition. The aim of this study has been to examine such common relations for cellulitis and pharyngitis. The hypothesis is that ambient ground-level ozone may help bacteria to penetrate skin or throat. Material and Methods: We used the emergency department (ED visits data in Edmonton, Canada for the period from 1992 (April to 2002 (March. We retrieved all the diagnosed ED visits for cellulitis and pharyngitis. Case-crossover design was used to study potential association between ozone and those visits. Conditional logistic regression was used to estimate odds ratios (OR and their 95% confidence intervals (95% CI. Results: The results are reported for the interquartile range (IQR = 17.9 ppb for 8 h maximum ozone. Positive and statistical significant results were obtained as follows: for lags from 0 to 3 (OR = 1.07, 95% CI: 1.03–1.12, lag 2; for lags from 0 to 6 days (OR = 1.08, 95% CI: 1.03–1.12, lag 3; for lags from 0 to 4 (OR = 1.06, 95% CI: 1.03–1.09, for lag 2 and 3. Conclusions: The findings suggest the response to exposure to ambient ground-level ozone for skin and pharyngitis considered separately and jointly.

    To characterise the Emergency Department (ED) prevalence of cellulitis, factors predicting oral antibiotic therapy and the utility of the Clinical Resource Efficiency Support Team (CREST) guideline in predicting patient management in the ED setting, a prospective, cross-sectional study of consecutive adult patients presenting to 3 Irish EDs was performed. The overall prevalence of cellulitis was 12 per 1,000 ED visits. Of 59 patients enrolled, 45.8% were discharged. Predictors of treatment with oral antibiotics were: CREST, Class 1 allocation (odds ratio (OR) 6.81, 95% Cl =1.5-30.1, p=0.012), patient self-referral (OR= 6.2, 95% Cl 1.9- 20.0, p=0.03) and symptom duration longer than 48 hours (OR 1.2, 95% Cl = 1.0-1.5,p=0.049). In conflict with guideline recommendation, 43% of patients in CREST Class 1 received IV therapy. Treatment with oral antibiotics was predicted by CREST Class 1 allocation, self-referral, symptom duration of more than 48 hours and absence of pre-EO antibiotic therapy.

    Full Text Available We illustrate a case involving a 51-year-old man who presented to a tertiary hospital with sepsis secondary to an abscess of the nasal vestibule and pustular eruptions of the nasal mucosa. Associated cellulitis extended across the face to the eye, and mucosal thickening of the sinuses was seen on computed tomography. The patient underwent incision and drainage and endoscopic sinus surgery. Blood cultures and swabs were positive for a gram-negative bacillus, Burkholderia pseudomallei. He had multiple risk factors including travel to an endemic area. The patient received extended antibiotic therapy in keeping with published national guidelines. Melioidosis is caused by Burkholderia pseudomallei, found in the soil in Northern Australia and Asia. It is transmitted via cutaneous or inhaled routes, leading to pneumonia, skin or soft tissue abscesses, and genitourinary infections. Risk factors include diabetes, chronic lung disease, and alcohol abuse. It can exist as a latent, active, or reactivated infection. A high mortality rate has been identified in patients with sepsis. Melioidosis is endemic in tropical Northern Australia and northeastern Thailand where it is the most common cause of severe community-acquired sepsis. There is one other report of melioidosis in the literature involving orbital cellulitis and sinusitis.

    Full Text Available Juvenile cellulitis or juvenile sterile granulomatous lymphadenitis is a rare disorder that affects puppies between three weeks to six months years old. Clinical signs include alopecia, edema, papules, pustules and crusts especially on eyelids. Definitive diagnosis requires cytological and histological evaluation and early and aggressive therapy is recommended, once scars after recovery can be severe .The choice treatment is the high dose of corticosteroids use such as prednisone. Three animals of canine species were attended at the Veterinary Hospital Clinical Small Animal Service presenting different clinical signs. Hemogram, skin lesions and submandibular lymph nodes cytological examination was collected and analyzed. The treatment was instituted, using cephalexin (22mg/kg, twice daily up to control of secondary bacterial infection, and prednisone (2mg/kg, once a day until clinical resolution. Complete cure was obtained at the end of treatment. The aim of this work is to report three clinical cases of juvenile cellulitis in dogs. A celulite juvenil ou linfadenite granulomatosa estéril juvenil, é um distúrbio raro que acomete filhotes com idade entre três semanas a seis meses. Os sinais clínicos incluem alopecia, edema, pápulas, pústulas e crostas especialmente em pálpebras. O diagnóstico definitivo requer exames citológico e histopatológico e a terapia precoce e agressiva é preconizada, pois as cicatrizes após recuperação podem ser graves. O tratamento de escolha consiste no uso de altas doses dos glicocorticoides, como prednisona. Foram atendidos no Hospital Veterinário, três animais da espécie canina, apresentando sinais clínicos variados. Foram realizados hemograma, exame citológico das lesões de pele e dos linfonodos submandibulares. O tratamento foi instituído, utilizando-se cefalexina na dose de 22 mg/kg, duas vezes ao dia, até controle de infecção bacteriana secundária e prednisona na dose de 2mg/kg, uma vez

    Full Text Available Abstract Background Cryptococcus neoformans is an encapsulated yeast and the most frequent cryptococcal species found in humans. Cryptococcosis is considered an opportunistic infection as it affects mainly immunosuppressed individuals. In humans, C. neoformans causes three types of infections: pulmonary cryptococcosis, cryptococcal meningitis and wound or cutaneous cryptococcosis. Case Presentation An 81-year-old woman developed severe necrotizing cellulitis on her left arm without any preceding injury. The patient had been treated with systemic corticosteroids over twenty years for rheumatoid arthritis (RA. Skin biopsies of the wound area were initially interpreted as cutaneous vasculitis of unknown etiology. However, periodic acid Schiff staining and smear analysis later revealed structures consistent with Cryptococcus neoformans, and the infection was subsequently confirmed by culture. After the initiation of therapy with fluconazole 400 mg per day the general condition and the skin ulcers improved rapidly and the patient was discharged to a rehabilitation facility. Subsequently surgical debridement and skin grafting were performed. Conclusions Opportunistic infections such as cryptococcosis can clinically and histologically mimic cutaneous vasculitis and have to be investigated rigorously as a differential diagnosis in immunosuppressed patients.

    Serratia marcescens is an unusual cause of severe skin infection initially described in immunocompromised patients. We report a case of necrotizing cellulitis of the leg caused by S marcescens in a 68-year-old woman with diabetes mellitus and a history of chronic lymphoedema of the leg. We reviewed the literature and found 49 cases of severe skin infections from S marcescens that included 20 cases of necrotizing fasciitis (NF) as well as 29 cases of severe skin infections without NF (non-NF cases). Patients were immunocompromised in 59% to 70% of cases. The mortality rate was high in NF cases (60%) versus non-NF cases (3%). Surgery was required in 95% of NF cases and in 24% of non-NF cases. The other clinical manifestations of S marcescens skin infection reported in the literature included disseminated papular eruptions in patients infected with human immunodeficiency virus with folliculitis on the trunk. Serratia marcescens is naturally resistant to amoxicillin alone and amoxicillin associated with clavulanic acid. Broad-spectrum antibiotics are indicated to treat S marcescens skin infections, and surgery should be promptly considered in cases of severe skin infections if appropriate antibiotic therapy does not lead to rapid improvement.

    We report a rare case of orbital cellulitis occurring secondary to a dental infection followed by therapeutic (orthodontic) extraction. A 16 year old female patient presented to the dental office with a left orbital proptosis for the past 4 days. PNS view, CT scan revealed an abscess in relation to medial, lateral superior inferior walls of the orbit associated with naso ethmoidal and left maxillary sinus. Through nasal endoscopy, middle meatus antrostomy and ethmoidectomy was performed for the drainage of pus from the orbit, ethmoid and maxillary sinus under general anesthesia. Immediately regression of orbital swelling was noticed. Eyeball movements improved. Epiphora reduced and proptosis declined. With the advent of higher antibiotics, orbital infection rarely occurs secondary to dental causes except in a very few cases. Complete elimination of pus from orbital cavity, para nasal air sinuses and appropriate antibiotic coverage at the earliest forms the mainstay of treatment. The nasal endoscopic approach with orbital decompression is the most acceptable atrumatic, cosmetic and functional procedure. PMID:22942598

    Many species have been drastically affected by rapid urbanization. Harris's hawks from their natural habitat of open spaces and a supply of rodents, lizards and other small prey have been forced to change their natural environment adapting to living in open spaces in sub- and peri-urban areas. Specific areas include playgrounds, parks and school courtyards. The migration of this predatory species into these areas poses a risk to individuals, and especially the children are often attacked by claws, talons and beaks intentionally or as collateral damage while attacking rodent prey. In addition, the diverse micro-organisms harbored in the beaks and talons can result in wound infections, presenting a challenge to clinical management. Here we would like to present a case of an80-year-old man with cellulitis of both hands after sustaining minor injuries from the talons of a Harris's hawk and review the management options. We would also like to draw attention to the matter that, even though previously a rarity, more cases of injuries caused by birds of prey may be seen in hospital settings.

    Full Text Available Introduction: Comparative effectiveness and efficacy research for analysis and practice (CEERAP was performed to assess the effects of penicillin-based versus erythromycin-based antibiotic treatments in patients with skin and soft tissue infections (SSTIs including cellulitis, impetigo, and erysipelas. Because SSTIs, especially orofacial cellulitis, are volatile infectious diseases of a life-threatening nature, research on the most efficacious remedies is necessary. Methods: The stringent bibliome yielded three systematic reviews, which were examined for quality of research synthesis protocol and clinical relevance. Results: The sample size of three, rendered the statistical analyses and cumulative meta-analysis problematic. Conclusion: The systematic review outlined here should aid in increasing clinical awareness, improving patient health literacy, and promoting consensus of the best evidence base (BEB to mitigate the threat of sepsis and potential death caused by cellulitis infections.

    Human immunodeficiency virus (HIV)-infected patients are at a high risk of cancer compared with the general population. As the use of antiretroviral therapy (ART) has increased, non-AIDS-defining cancers have also increased in the past decade. A 61-year-old man with HIV infection on ART developed a painful, erythematous and oedematous lower left leg and an associated fever. He was initially treated with antibiotics for cellulitis but there was no improvement, which warranted further investigation. A translucent lesion was found by X-ray imaging and bone scintigraphy showed bone metastasis from a primary adenocarcinoma of the lung, documented by chest computed tomography and an axillary lymph node biopsy. The patient died three months after the diagnosis despite undergoing chemotherapy. This case demonstrates that physicians should consider metastatic malignancies as a differential diagnoses for diverse skin changes in HIV-infected patients. PMID:26404113

    The chlorophyllin (CHLN) is a porphyrin of nutritious grade and soluble in water, derived of the chlorophyll. It has been reported that this pigment is a good anti mutagen since it reduces the damage to the DNA caused by physical or chemical agents of direct or indirect action. Their anti carcinogenic action has also been demonstrated when it is administered itself during the induced post-initiation phase by aflatoxins and heterocyclic amines. However in the last decade it has been reported that it also has promoter activity against the genetic damage induced by diverse agents like the alkyl ants of direct and indirect action, the gamma radiation and some heterocyclic amines. This effect has been observed in testing systems like Salmonella, Drosophila, rainbow trout and rodents. In the mouse spermatogonia it has been reported that it reduces the damage to the DNA but with the test of lethal dominant in Drosophila increment the damage induced by gamma radiation. The present study consisted on evaluating the effect of the CHLN in the line germinal masculine of Drosophila by means of the lethal recessive test bound to the sex (LRLS) with the stump Muller 5 and a litters system. Its were pretreated wild males with CHLN and 24 h later were irradiated with 0, 10, 20 and 40 Gy of gamma radiation immediately later were crossed with virgin females of the stump Basc and at 72 h the male was transferred to a cultivation media with three new virgin females, this process repeated three times until completing 3 litters. The F1 it was crossed among itself and in the F2 it was analysed the presence or absence of lethals. The results indicated that the CHLN per se incremented the basal frequency of damage due to the pigment can act as an agent that is inserted to the ADN causing pre mutagenic leisure. Nevertheless with the groups treated with the different doses of gamma radiation the CHLN does not present any protector action, neither promoter except in the litter I of the group

    The chlorophyllin (CHLN) is a derived of the chlorophyll in the one which the atom of Mg is replaced by Cu. It has been broadly used as preservative in those foods, and in the treatment of geriatric patients. The results using different test systems have demonstrated that the CHLN reduces the DNA damage caused by different physical agents or chemical of direct action or insinuation. Another of the properties of the CHLN is it anti carcinogenic action, because it has been that inhibits the carcinogen activity of B1 (AFB1) aflatoxin and it diminishes the incidence of tumors caused for 2-amine-3-methylimidazo [4- 5f] quinoline (IQ) and it inhibits the development of colon cancer during the post-initiation phase. Recently the reports of the activity promoter of the CHLN have been increased on the genetic damage. This effect observed in Salmonella and later on in Drosophila melanogaster using, physical and chemical agents. Presently study determines the action of the CHLN before the genetic effect induced in germinal cells of Drosophila melanogaster by means of the test of the lost one of the X chromosome in ring using two protocols; the first one consisted on pretreatment with CHLN to the male ones and later on to irradiate them and in the second protocol the pretreatment with CHLN administers to the females, in both protocols its were used a litter systems.

    Full Text Available Abstract Background This paper describes the results of a feasibility study for a randomised controlled trial (RCT. Methods Twenty-nine members of the UK Dermatology Clinical Trials Network (UK DCTN expressed an interest in recruiting for this study. Of these, 17 obtained full ethics and Research & Development (R&D approval, and 15 successfully recruited patients into the study. A total of 70 participants with a diagnosis of cellulitis of the leg were enrolled over a 5-month period. These participants were largely recruited from medical admissions wards, although some were identified from dermatology, orthopaedic, geriatric and general surgery wards. Data were collected on patient demographics, clinical features and willingness to take part in a future RCT. Results Despite being a relatively common condition, cellulitis patients were difficult to locate through our network of UK DCTN clinicians. This was largely because patients were rarely seen by dermatologists, and admissions were not co-ordinated centrally. In addition, the impact of the proposed exclusion criteria was high; only 26 (37% of those enrolled in the study fulfilled all of the inclusion criteria for the subsequent RCT, and were willing to be randomised to treatment. Of the 70 participants identified during the study as having cellulitis of the leg (as confirmed by a dermatologist, only 59 (84% had all 3 of the defining features of: i erythema, ii oedema, and iii warmth with acute pain/tenderness upon examination. Twenty-two (32% patients experienced a previous episode of cellulitis within the last 3 years. The median time to recurrence (estimated as the time since the most recent previous attack was 205 days (95% CI 102 to 308. Service users were generally supportive of the trial, although several expressed concerns about taking antibiotics for lengthy periods, and felt that multiple morbidity/old age would limit entry into a 3-year study.

In the present study, we examined 19 men who did not have major risk factors that might affect bone mass. Parathormone(PTH, osteocalcin (marker of bone formation, OC and deoxypyridinoline (marker of bone resorption, DPD were measured. The bone mineral density (BMD measurements in 16 men were performed by dual-energy X-ray absorbtiometry (DXA from lumbar spine (L2-4, and left hip. Bone density at each site was categorized as osteoporosis or osteopenia according to World Health Organization (WHO criteria. In 19 patients with a mean age of 69 years, PTH levels were in the normal range except one patient. OC levels were elevated in %42.1 and DPD levels were elevated in 74 % of patients. L2-4 T score was osteoporotic (25% in 4 patients and osteopenic (25% in 4 patients. Femur Ward’s T score was osteoporotic (37.5% in 7 patients and osteopenic (37.5% in 7 patients. Osteoporosis is a significant problem in older men. Increased awareness for the risk factors of male osteoporosis is an important issue. Early diagnosis and treatment would help to reduce morbidity and mortality resulting from osteoporotic fractures.

    Full Text Available PURPOSE: To describe the CT findings of orbital cellulitis due to sinusitis. METHODS: The records and CT scans of 45 consecutive patients with orbital cellulitis due to sinusitis treated at the Hospital of the Medical School of Ribeirão Preto were analyzed by a radiologist and two orbital surgeons. RESULTS: Three major types of CT changes were observed: diffuse fat infiltration, subperiosteal abscess and orbital abscess. Diffuse fat infiltration (characterized by an increased density of the extra- or intraconal fat was seen in 11 patients (24.44%. A subperiosteal abscess was diagnosed in 28 patients (62.23%. A surgically proved orbital abscess was detected in 6 patients (13.33%. CONCLUSIONS: In all cases of orbital cellulitis due to sinusitis intraorbital changes can be detected by CT scans either as a diffuse infiltration of the orbital fat or as a detachment of the periorbita (subperiosteal abscess or a true orbital abscess. Category I of Chandler orbital cellulitis classification (inflammatory edema must be understood as a stage of a process that is already happening within the orbit and, as the term "preseptal cellulitis" means a palpebral infection, this designation should not be used to stage orbital cellulitis.OBJETIVO: Descrever os achados tomográficos em celulites orbitárias secundárias à sinusite.

  1. The role of 99mTc-labelled stannous colloid white blood cells scanning in the evaluation of and differentiation between cellulitis and osteomyelitis

    International Nuclear Information System (INIS)

    Full text: Sequential 99mTc-MDP and 67Ga-citrate scanning have been extensively used in the evaluation of infection. 99mTc-labelled stannous colloid white blood cell (Tc-WBC) is not widely reported. A prospective study was undertaken in 92 patients to assess Tc-WBC and Tc-MDP scanning in this clinical application. Labelling efficiency (LE) was calculated with a mean ± SD of 94 ± 4.8 %. Patients (6) who were treated with gentamycin had an LE ± SD of 70 ± 9%. Twenty six patients treated as osteomyelitis had congruent abnormalities on Tc-WBC and Tc-MDP scans. Twenty one patients treated as cellulitis had abnormalities demonstrated on Tc-WBC but not on Tc-MDP scans. Tc-WBC appeared to define areas of inflammation of bone and soft-tissue in the hands or feet more distinctly than Tc-MDP. Fourteen patients had progress Tc-WBC scans 4-6 weeks following antibiotic treatment. Changes in scan appearances seemed to mirror the clinical course of the patients. Tc-WBC and Tc-MDP scans were useful complementary studies in the diagnosis, evaluation and assessment of treatment in patients with cellulitis and osteomyelitis

    Full Text Available Abstract Background Diabetic muscle infarction is a rare complication of diabetes mellitus (DM and is often misdiagnosed as cellulitis. This complication is usually associated with poor disease prognosis and high mortality with previous studies reporting a risk of 50% recurrence or another macrovascular complication occurring within one year. Thus, there needs to be greater awareness of this complication of diabetes. Case presentation In the current work, we present a case report and literature review of DMI occurring in a calf of a 57 year old male. However, unlike the suspected trend, our patient has performed well after this incident and has not sustained another macrovascular event now > 15 month since his original diabetic muscle infarction. Conclusion Even though diabetic muscle infarction is an uncommon condition, it is important to consider this diagnosis in a diabetic patient. We hope that our findings and literature review will aid clinicians to better diagnose and manage this condition.

    Full Text Available Abstract Introduction Campylobacter is an important causative agent of intestinal infections in humans. Bacteremia is detected in less than 1% of patients, mainly in immunocompromised patients and in extreme age groups. Cellulitis is a relatively common manifestation of Campylobacter infection, but concomitant bacteremia is a rare event. Infections of the pacemaker area are caused primarily by staphylococci, followed by fungi, streptococci and Gram-negative rods. To the best of our knowledge, this is the first case report of pacemaker pocket infection and bacteremia caused by Campylobacter fetus. Case presentation A 72-year-old Croatian Caucasian man with myelodysplasia, impaired fasting glucose levels and a recently implanted permanent pacemaker was admitted to hospital after six days of fever, development of red swelling of the pacemaker pocket area and worsening of his general condition. No antibiotic therapy was introduced in the outpatient setting. He denied any recent gastrointestinal disturbances. With the exception of an elevated leukocyte count, erythrocyte sedimentation rate, and C-reactive protein and blood glucose levels, other laboratory findings were normal. Treatment with vancomycin plus netilmicin was introduced, and a surgical incision with drainage of the pacemaker pocket was performed. The entire pacemaker system was removed and a new one re-implanted after 14 days of antibiotic therapy. Transesophageal echocardiography showed no pathological findings. Three subsequent blood cultures obtained on admission as well as swab culture of the incised pacemaker area revealed Campylobacter fetus; stool and pacemaker lead cultures were negative. According to the microbiological results, antibiotic therapy was changed to ciprofloxacin plus netilmicin. A clinical examination and the results of a laboratory analysis performed after two weeks of therapy were within normal limits. Conclusion Myelodysplasia, impaired fasting glucose levels

  10. Etude des phenomenes chimiques au contact entre le bloc cathodique et la barre collectrice d'une cellule d'electrolyse d'aluminium

    Science.gov (United States)

    Lebeuf, Martin

    La production d'aluminium est une industrie importante au Québec. Les propriétés de ce métal le vouent à de multiples usages présents et futurs dans le cadre d'une économie moderne durable. Toutefois, le procédé Hall-Héroult est très énergivore et des progrès demeurent donc nécessaires pour en diminuer les coûts financiers et environnementaux. Parmi les améliorations envisageables de la cellule d'électrolyse se trouve le contact entre la cathode et la barre collectrice, qui doit offrir une faible résistivité au passage du courant électrique. En cours d'opération de la cellule, ce contact a tendance à se dégrader, générant des pertes énergétiques significatives. Les causes de cette dégradation, pouvant provenir de phénomènes chimiques, thermiques, mécaniques et/ou électriques, demeurent mal comprises. Le but du présent projet était donc d'étudier les phénomènes chimiques se produisant au contact bloc-barre de la cellule d'électrolyse Hall-Héroult. En premier lieu, un aspect crucial à considérer est la pénétration du bain électrolytique dans la cathode, car des composés de bain atteignent éventuellement la barre collectrice et peuvent y réagir. A cet effet, une méthode novatrice a été développée afin d'étudier les cathodes et la pénétration du bain dans celles-ci à l'aide de la microtomographie à rayons X. Cette méthode rapide et efficace s'est avérée fort utile dans le projet et a un potentiel important pour l'étude future des cathodes et des phénomènes qui s'y produisent. Ensuite, une cellule d'électrolyse rectangulaire à petite échelle a été développée. Plusieurs phénomènes observés 'en industrie sur des autopsies de cellules post-opération et rapportés dans la littérature ont été reproduis avec succès à l'aide de cette cellule expérimentale. Puis, des tests sans électrolyse, ciblant l'effet du bain électrolytique sur l'acier, ont aussi été conçus et complétés afin de s

    2016-09-01

    Precautionary recommendations conveyed to survivors of cancer by health-care practitioners to reduce the risk of breast cancer-related lymphoedema are indispensable aspects of clinical care, yet remain unsubstantiated by high-level scientific evidence. By reviewing the literature, we identified 31 original research articles that examined whether lifestyle-associated risk factors (air travel, ipsilateral arm blood pressure measurements, skin puncture, extreme temperatures, and skin infections-eg, cellulitis) increase the risk of breast cancer-related lymphoedema. Among the few studies that lend support to precautionary guidelines, most provide low-level (levels 3-5) or inconclusive evidence of an association between lymphoedema and these risk factors, and only four level 2 studies show a significant association. Skin infections and previous infection or inflammation on the ipsilateral arm were among the most clearly defined and well established risk factors for lymphoedema. The paucity of high-level evidence and the conflicting nature of the existing literature make it difficult to establish definitive predictive factors for breast cancer-related lymphoedema, which could be a considerable source of patient distress and anxiety. Along with further research into these risk factors, continued discussion regarding modification of the guidelines and adoption of a risk-adjusted approach is needed. PMID:27599144

    Full Text Available Infertility by definition, is not to get pregnant within one year of regular sexual relationship without protection, affects 15-20% of reproductive age couples. Approximately 30% of infertility cases are male originated. Male infertility is caused by endocrine-related genetic defects affecting urogenital system function. These defects adversely affect subsequent spermatogenesis, sexual function, fertility, early embryonic stage of sexual maturation. Autosomal and gonosomal, numerical and structural chromosome abnormalities and related syndromes rank at the top causes of male infertility. Similar chromosome abnormalities are detected in male infertility and as the rate of these abnormalities increase, it was found to reduce sperm count especially in azospermic and oligozoospermic men.

  15. Targeting the adolescent male.

    Pitt, E

    1986-01-01

    The National Urban League regards too early parenting among adolescents as an issue requiring high level, active attention from all segments of the Black community. Poverty, single parent households and adolescent pregnancies are not exclusively female problems. The role that males play has been missing from too many studies of these phenomena. In light of the fact that most sexual activity is male initiated, and most sexual behavior is male influenced, it becomes clear that there will be no resolution of the problem of teenage pregnancy without directing greater attention to the male. The issue of male responsibility is skirted too often due to parental pride on the part of mothers and fathers when their male children seek sexual relations with female partners. It is viewed as a sign that they are developing sexually within the norm. This is especially true, in many instances, in female headed households where the mother is concerned that she may not be providing her son with an adequate male role model. Sexual activity by female adolescents, however, is generally not condoned. This confusing double standard is further compounded by the disjointed fashion in which American society responds to adolescent sexuality on the whole. Although the home should be the focal point, many parents reluctantly admit an inability to communicate effectively about sex with their pre-adolescent children. Thus, the school, church, community and social agencies have all been enlisted in this task. The National Urban League's initiative in this area is expected to have significant impact on the course of adolescent sexuality and reproductive responsibility.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:3745498

    Within the framework of the 'Rapsodie' fast reactor program, prototype plutonium fuel elements are irradiated and then examined in an {alpha} {beta} {gamma} laboratory at Saclay. This laboratory consists of five in line cells and a lead enclosure microscope. Each cell contains an {alpha} sealed removable box 4 ft 3 in. high, 4 ft 11 in. wide and 5 ft 1 in. deep, fitted with one or two magnetic transmission indirect manipulators. The boxes are contained in an {beta} {gamma} shielded enclosure whose front face is constructed of cast iron panels 21-2/3 in. thick. Nitrogen circulating in a closed loop forms the atmosphere of the boxes. This laboratory is essentially intended for metallurgical research. The functions of the various cells are as follows: transferring and packing, cutting, density measurement and cathodic etching, storage and metallography. Work on radioactive materials began in April 1961. Operational incidents have always been of a material nature only.

    Homosexology is that branch of the science of sexology that deals with same sex relationships. It is subdivided into ideation, imagery, and praxis. Praxeology is the science of praxis. There are two doctrines by which homosexuality is defined: elective and developmental. Elective is like joining a political party and is more likely bisexual than exclusively homosexual. Complete developmental homosexuality is a state of being and is characteristically immutable. Both types of homosexuality are determined multivariately and sequentially, not univariately. Male and female mammals are phylogenically programmed to be reciprocal, not identical, in the praxeology of their courtship and mating. In primate, notably human, evolution, the eyes have taken over from the nose as organs of erotic arousal, but the molecular biology of how this happens in individual development, gay, straight or ambivalent, remains to be ascertained. The different personal histories of homosexual development also remain to be ascertained and cataloged. PMID:15506674

  20. Genetically conditioned male sterility

    International Nuclear Information System (INIS)

    A survey is given of two different types of genetically controlled male sterility in higher plants. 'Functional' male sterility is due to the action of mutated genes causing a misdifferentiation of the growing points in different specific ways. Under the influence of the genes of this group either the stamens or the archespore tissues are not differentiated. In other mutants functionable male germ cells are produced but cannot be used for fertilizing the egg cells because the anthers remain closed or anthers and stigma become spatially separated from each other. Other genes of the group are responsible for the transformation of stamens into carpels, i.e. for a change of the hermaphrodite flower into a unisexually female one. A second type of male sterility is due to the action of ms genes influencing the course of micro-sporogenesis directly. They cause the breakdown of this process in a specific meiotic stage characteristic for each gene of the group. This breakdown is introduced by the degeneration of PMCs, microspores, or pollen grains preventing the production of male germ cells. The female sex organs remain uninfluenced. (author)

    The cupro-sodium chlorophyllin (CCS) it is a soluble porphyrin in water that it includes in its it structures a copper atom instead of the magnesium that has the chlorophyll. Diverse experiments have demonstrated that it possesses a potent activity, reducing or inhibiting, the DNA damage caused by physical and chemical agents of direct action or insinuation. Most of the knowledge about their anti genotoxic activity has been obtained using somatic cells of different organisms, on the other hand it is known very little of their effect in germinal cells. At the moment in the Drosophila laboratory of the ININ it is investigating the protective action of the CCS in germinal cells, with these studies has been observed that its administration to females that were crossed with males irradiated with 20 Gy of gamma radiation, promotes the induction of lethal dominant in the embryonic and post-embryonic states causing a diminution in the viability egg-adult. With the test of lethal recessive bound to the sex one has evidence that it increases the basal frequency of lethal recessive and it doesn't reduce those induced by radiation. In contrast, with the present investigation when the CCS was administered to males that later on were treated with ethyl-nitroso-urea (ENU) caused a reduction of the lethal frequency in all the monitored cellular states, but only it was significant in the post-meiotic cells. On the contrary, when the CCS was administered to the female ones and then they crossed with males treaties with ENU, it was observed a tendency to increase the lethal ones in all the cellular types. With both protocols the CCS caused a diminution of the sterility. The fact that the CCS has antagonistic activities, it deserves special attention to investigate with different protocols and systems, the conditions in that this pigment can work as a true antimutagenic and/or anti carcinogenic before being able to him to propose as a chemopreventor.

    Tortoiseshell coat color is normally restricted to female cats due to X-linkage of the gene that encodes the orange coat color. Tortoiseshell male cats do, however, occur at a low frequency among tortoiseshell cats because of chromosome aberrations similar to the Klinefelter syndrome in man...... tissue from a tortoiseshell male cat referred to us. Chromosome analysis using RBA-banding consistently revealed a 39,XXY karyotype. Histological examinations of testis biopsies from this cat showed degeneration of the tubules, hyperplasia of the interstitial tissue, and complete loss of germ cells....... Immunostaining using anti-vimentin and anti-VASA (DDX4) showed that only Sertoli cells and no germ cells were observed in the testicular tubules. As no sign of spermatogenesis was detected, we conclude that this is a classic case of a sterile, male tortoiseshell cat with a 39,XXY chromosome complement. © 2013 S...

    Full Text Available Abstract Before sterile mass-reared mosquitoes are released in an attempt to control local populations, many facets of male mating biology need to be elucidated. Large knowledge gaps exist in how both sexes meet in space and time, the correlation of male size and mating success and in which arenas matings are successful. Previous failures in mosquito sterile insect technique (SIT projects have been linked to poor knowledge of local mating behaviours or the selection of deleterious phenotypes during colonisation and long-term mass rearing. Careful selection of mating characteristics must be combined with intensive field trials to ensure phenotypic characters are not antagonistic to longevity, dispersal, or mating behaviours in released males. Success has been achieved, even when colonised vectors were less competitive, due in part to extensive field trials to ensure mating compatibility and effective dispersal. The study of male mating biology in other dipterans has improved the success of operational SIT programmes. Contributing factors include inter-sexual selection, pheromone based attraction, the ability to detect alterations in local mating behaviours, and the effects of long-term colonisation on mating competitiveness. Although great strides have been made in other SIT programmes, this knowledge may not be germane to anophelines, and this has led to a recent increase in research in this area.

    Male breast cancer (MaleBC) is a rare disease, accounting for development; low-penetrance gene mutations (i.e. CHEK-2) are more common but involve a lower risk increase. About 90% of all male breast tumors have proved to be invasive ductal carcinomas, expressing high levels of hormone receptors with evident therapeutic returns. The most common clinical sign of BC onset in men is a painless palpable retroareolar lump, which should be evaluated by means of mammography, ultrasonography and core biopsy or fine needle aspiration (FNA). To date, there are no published data from prospective randomized trials supporting a specific therapeutic approach in MaleBC. Tumor size together with the number of axillary nodes involved are the main prognostic factors and should guide the treatment choice. Locoregional approaches include surgery and radiotherapy (RT), depending upon the initial clinical presentation. When systemic treatment (adjuvant, neoadjuvant and metastatic) is delivered, the choice between hormonal and or chemotherapy (CT) should depend upon the clinical and biological features, according to the FBC management guidelines. However great caution is required because of high rates of age-related comorbidities. PMID:19427229

Ces travaux ont permis de préciser le rôle essentiel joué par les micro-domaines de glycosphingolipides au cours de la fusion virus-cellule. En particulier, nous avons pu reconstituer un complexe de fusion fonctionnel faisant intervenir les différents partenaires moléculaires de la fusion : un micro-domaine de glycosphingolipide se présentant sous la forme d’un film monomoléculaire à l’interface eau-air, le récepteur CD4 et la glycoprotéine externe de l’enveloppe du virus, la gp120. La dynamique des interactions moléculaires dans ce complexe de fusion a pu être mesurée à l’aide d’un micro-tensiomètre. Ce système expérimental pourrait permettre d’évaluer l’activité d’inhibiteurs de fusion tels que des analogues synthétiques de glycosphingolipides.

    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

    1998-04-01

    DNA double-strand breaks (DSB) are the likely event which may explain the radiation-induced killing effect in mammalian cells. An overview of the litterature shows that, to the exception of a small group of human tumours, the repair defect rather than the induction rate of DSB plays the major role. However, the arguments supporting the relationship between DSB and intrinsic radiosensitivity are most often indirect. Our results dealing with intrinsic radiosensitivity, residual DNA DSB and chromosome breaks have been achieved with untransformed human fibroblasts (5 control and 18 hypersensitive cell lines). We describe a quantitative relationship between the intrinsic radiosensitivity and the residual breaks. The death of a human fibroblast is linked to 1.3 unrepaired chromosome break and 6.6 unrepaired DSB. Les cassures double-brin (CDB) de l'ADN constituent l'événement-clé susceptible d'expliquer l'effet létal des radiations ionisantes. Une revue générale de la littérature montre que, à l'exception d'un groupe minoritaire de tumeurs humaines, c'est surtout une déficience de réparation plutôt que l'incidence des dégâts qui est associée à la mort des cellules de mammifères irradiées. Toutefois, les arguments en faveur d'un lien entre radiosensibilité et CDB sont généralement indirects. À partir de 23lignées fibroblastiques humaines (5témoins et 18hypersensibles), nous décrivons une relation quantifiée entre la radiosensibilité intrinsèque et les cassures résiduelles de l'ADN et des chromosomes. La mort d'un fibroblaste humain irradié est associée à 6,6 CDB et 1,3 cassure chromosomique non réparées.

    A sample of 100 adolescent males enrolled in 2 high schools in suburban New Jersey completed a 30 item questionnaire in 1980 to explore further the attitudes and intended behavior of white, middle-class adolescent males regarding their reproductive responsibility. Data were sought on attitudes toward sex, contraception, pregnancy, and fatherhood. Also questioned were preferences about contraceptive use as well as anticipated behavior in the event of a partner's pregnancy. The study also was designed to obtain information on responses the subjects anticipated from their paretns on preferred pregnancy outcome. All respondents were white. 94%, based on data on the subjects' fathers, were ranked middle class and higher according to Hollingshead's Two Factor Index of Social Position. Ages ranged from 15-19 with a mean age of 16. 88% were living in households with both parents. Only 4% agreed that there was nothing wrong with telling a girl that you love her (even if you do not) so that she will agree to have sexual relations. This contrasts markedly with 61% of Vadies and Hale's lower-class sample of adolescent males who felt that deception was acceptable to obtain sex. 59% of the study group agreed that contraceptive use "shows concern for the girl," but the percentage dropped slightly to 53% regarding attitude toward using "protection whenever possible." The subjects demonstrated a contrast between attitude and intended behavior with 67% indicating an intention to use contraception when participating in sex regularly. 62% thought that for most of their peers would have sex and count on luck. 54% assumed that the "girl will protect herself." Respondents were more often willing either to help the close girlfriend range an abortion (28%), to marry her (21%), or to help her seek an adoption (20%). They were less likely to do the same for a casual girlfriend except in the case of abortion. A double standard was significantly evident on the basis of several preferred types

    Progress in medically assisted procreation has made it possible to obtain an embryon with a single spermatozoid or even a single spermatid. But such advanced technology must not overshadow the basic principles of patient management since there are many other medical or surgical possibilities for improving male fertility. Although the physiological mechanisms leading to azoospermia are relatively well understood, many questions remain as to the origin of oligo-asthenoteratospermia. Varicocela had been incriminated by many authors: in 25% of the cases, surgical care is followed by pregnancy. Other factors including autoimmunity, infection, environment and drugs also have an effect. Careful history taking can identify the main causes of male infertility before the problem of procreation occurs and in cases of definitive azoospermia the principles of management are relatively simple. The true problem is the fact that new techniques such as in vitro fertilization have acquired popularity in the general population but cannot be accepted as the gold standard by the medical community. It must not be forgotten that these artificial techniques cause a major psychological trauma to the couple and can lead to difficult situations (multiple pregnancies, extra embryos) with no totally satisfactory solution.

    In young male patients who suffered several kinds of trauma with subsequent suspicious reflex sympathetic dystrophy syndrome, we performed three-phasic bone scan in order to investigate its usefulness. Patients with narrow range of age (21-25. mean 22.8 {+-}1.3, all male) were included with suspicious reflex sympathetic dystrophy syndrome of 12 feet and 5 hands. Only one was bilateral feet case and 16 were ipsilateral (Rt:13, Lt:3). The etiologic traumas were 4 fractures, 4 sprains, 3 blunt trauma, 2 cellulitis, 1 tendon teat, 1 crush injury, 1 overexercise, and 1 unknown. Radiologically 3 showed osteoporotic changes. Three-phasic bone scans were performed 21.1 {+-}7.3 wks after trauma. According to symptom complex, confirmatory reflex sympathetic dystrophy syndrome 4 cases and suspicious 13 were analyzed. All confirmatory cases (100%) showed increased uptake at delay phase with periarticular accentuation. Of confirmatory 4 cases, 2 showed increased uptake in all three phases (perfusion: P, blood pool: B, and delay: D), and other 2 revealed decreased P but, both increased B and D. Of suspicious 13 cases, 9(69.2%) had increased D (4 periarticular and 5 focal), 2 decreased D, and 2 symmetric D. In 12 foot cases, so-called weight bearing patterns-increased contralateral sole at P and B- were revealed in 7(58.3%). Diffuse periarticular increased uptake at delay phase of three-phasic bone scan was a compatible finding to reflex sympathetic dystrophy syndrome in young male patients whose symptom complex strongly designated post traumatic reflex sympathetic dystrophy syndrome.

  20. The sterile male technique: irradiation negatively affects male fertility but not male courtship.

    The sterile male technique is a common method to assign paternity, widely adopted due to its relative simplicity and low cost. Male sterility is induced by exposure to sub lethal doses of chemosterilants or irradiation, the dosage of which has to be calibrated for every species to provide successful male sterilisation, without affecting male physiology and behaviour. While the physiological effects of sterilisation are usually assessed for each study, the behavioural ones are rarely analysed in detail. Using the orb web spider Argiope keyserlingi as a model we first tested (1) the validity of the thread assay, which simulates male courtship behaviour in a standardised context, as a proxy representing courtship on a female web. We then investigated (2) the effectiveness of male sterilisation via irradiation and (3) its consequences on male courtship behaviour. Our results validate the thread assay and the sterile male technique as legitimate tools for the study of male courtship behaviour and fertilisation success. We show that these techniques are time and cost effective and reduce undesirable variation, thereby creating opportunities to study and understand the mechanisms underlying sexual selection.

    14 isoplasmic and allonuclear cytoplasmic male sterile lines were used as female parents, 8 tester lines as male parents, 101 F1 progenies were obtained. Fertility restoration response of 101 F1 progenies were investigated through field observation and pollen stainability examination under microscope. 14 isoplasmic and allonuclear cytoplasmic male sterile lines were developed by repeated backcross with recurrent male parent lines for more than 8 generations. The result shows: tester line Zifeng1 not only restored the isoplasmic and allonuclear sterile lines of group C backcrossed with Mo17, Yu30 and Heer, but also completely restored the isoplasmic and allonuclear cytoplasm male sterile lines of group T backcrossed with Mo17, HZS , 1792 ,292 and Yu30. Therefore, nuclear background limits the use of Zifeng1 as a tester for identification of cytoplasmic male sterility. Furthermore RFLPs of mitochondrial DNA of 6 isonuclear and alloplasmic cytoplasmic male sterile lines were analyzed with Bam H Ⅰ and Hind Ⅲ restriction endonuclease and mitochondrial DNA probes pBcmH3 and Cox Ⅱ. The same RFLPs were found within sterile cytoplasm of group C, including C,Chuan G, Lei 2 and Lei 3, but a different RFLP pattern was observed among sterile cytoplasm of group S, C,T and the normal cytoplasm. This result suggested that the RFLP markers tightly linked to sterile mitochondrial genes of different groups could be applied in the identifcation of cytoplasmic male sterility.

    alpha estradiol have been synthesized some of which show selectivity for the central nervous system. CNS effects have been demonstrated in female and male animals. Cardiovascular protection by estrogens has been shown in animal and human studies. Atherosclerotic plaque size was reduced after estrogen injections in cholesterol-fed rabbits. Phytoestrogen-fed monkeys had lower total cholesterol and LDL cholesterol and higher HDL cholesterol. Apart from atherosclerotic lesions, coronary artery vascular reactivity was improved. Some of these experimental findings were confirmed in human studies in postmenopausal women with and without estrogen treatment.

    As men are less likely than women to develop osteoporosis, male osteoporosis remains poorly understood. However, elderly men have a clearly reduced bone mineral density and increased risk for fractures. In Japan, one in four patients with osteoporosis is male. Male osteoporosis is associated with not only reduction in androgen, but also estrogen, and differs from postmenopausal osteoporosis in that decreased bone formation is involved and that age-related changes in cortical bone structure and perforation of the trabeculae of cancellous bone are unlikely to occur. The proportion of secondary osteoporosis is higher for men than women;therefore, differential diagnosis is important in the diagnosis of male osteoporosis. In addition, it is recommended that bone mineral density be measured at the femoral neck or total hip in men. Men have a worse prognosis following fractures than women, and management of male osteoporosis is highly important for extending healthy life expectancy. PMID:27346307

    Since the identification of thyroid hormone receptors on the testes, thyroid has been suggested to have a significant impact on the male reproductive tract, spermatogenesis, and male fertility. Several research articles on the role of thyroid in spermatogenesis or male infertility have been published in the last three decades. We conducted an exhaustive literature search was conducted in order to create an up-to-date review of literature. This review aims to discuss the impact of thyroid on testicular development, spermatogenesis, hypo- or hyper- thyroidism and male infertility, and the management of thyroid related abnormal semen profile. The literature revealed that thyroid significantly impacts testicular development and that abnormal thyroid profile affects semen quality and male fertility by compromising testicular size, sperm motility and ejaculate volume. A clear link exists between thyroid hormones, testicular development and spermatogenesis. Thyroid disease negatively affects spermatogenesis and consequently may cause male infertility. In such cases, infertility is reversible, but more studies need to be conducted, especially in post-pubertal males to cement the current findings. PMID:21622096

    Full Text Available Abstract Background Male breast cancer is a comparatively rare disease, and simultaneous bilateral male breast cancer is considered to be an extremely rare event. Risk factors are said to be genetic factors and hormonal abnormalities due to obesity or testicular diseases. Case presentation The patient was a 47-year-old Japanese male. His family had no history of female breast cancer. This patient also had hypospadias and hormonal examination indicated the presence of primary testicular potential hypogonadism, and these hormonal abnormalities seemed to be present since childhood or the fetal period. The bilateral breast cancer developed in this man at a comparatively young age, and histopathological studies of multiple sections showed that there was almost no normal epithelial cell in the ducts, while the ducts were almost completely filled with breast cancer cells. Conclusion It is thought that male breast cancer is caused by an imbalance between estrogen and testosterone. We cannot rule out the possibility that the breast cancer developed due to the effect of the slight elevation of estrogen over a long period of time, but the actual causative factors in this patient were unable to be definitively identified. In the future, we hope to further elucidate the causes of male breast cancer.

  18. [Male sexual and reproductive rights].

    In late 1997, PROFAMILIA began a study of the role of male sexual and reproductive rights as part of the construction of new masculine identities. The work was approached from the disciplines of law and sociology. Patriarchy, as a system of domination, permeated most cultures, giving men a position of power in relation to women and leading to a series of violent and self-destructive male behaviors. The patriarchal system imposed aggressive, promiscuous, risky, and irresponsible behaviors on men, which created a climate for sexual abuse, unwanted pregnancy, propagation of sexually transmitted diseases, and violence against women. Changes in female roles have created the need for changes in male roles. The most visible sexual and reproductive needs of men were studied through literature reviews and semistructured questionnaires with PROFAMILIA clients. Among the needs identified were a new type of male participation in family and domestic life, a new content for male sexual freedom, greater participation of men in reproductive decisions and in raising their children, and new ways of relating to others and sharing feelings and emotions. The need to avoid behaviors that put health at risk was also identified. A review of the evolution of existing sexual and reproductive rights and of the documents that constitute their ethical and juridical framework led to the conclusion that the construction of new rights specifically for men is not necessary, or juridically possible, in the current historical context.

    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 linea...

  1. Ferocious fighting between male grasshoppers.

    Directory of Open Access Journals (Sweden)

    Kate D L Umbers

    Full Text Available 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.

    Infertility rates among males with cystic fibrosis (CF) approximate 97%. No information is currently available within Ireland determining an understanding of fertility issues and the best methods of information provision to this specialized group. This study aimed to determine understanding and preferred approaches to information provision on fertility issues to Irish CF males. A Descriptive Study utilizing prospective coded questionnaires was mailed to a male CF cohort (n=50). Sections included demographics, fertility knowledge & investigation. Response rate was 16\\/50 (32%). All were aware that CF affected their fertility. More than two-thirds (n=11) were able to provide explanations whilst only one-third (n=5) provided the correct explanation. Significant numbers stated thoughts of marriage and a future family. Half have discussed fertility with a healthcare professional (HCP). Mean age of discussion was 21.9 years. One third preferred an earlier discussion. The commonest first source for information was written material which was also the preferred source. Three-quarters requested further information preferring again, written material. Significant gaps in sex education of Irish CF males exist. Discussion should be initiated by HCPs and centre-directed written material devised to address deficiencies.

  6. Conspicuous Coloration in Males of the Damselfly Nehalennia irene (Zygoptera: Coenagrionidae: Do Males Signal Their Unprofitability to Other Males?

    Directory of Open Access Journals (Sweden)

    Christopher D Beatty

    Full Text Available 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.

    Little documentation exists about male community health workers (promotores) networks. The experiences of promotores can provide input on how to attract, train, supervise and maintain male promotores in CHW programs. We present the experience and perspectives of promotores who participated in a male promotores network assisting Latino immigrant men in an emerging Latino community. All promotores in this community-based participatory study received payment for work 10 hours a week. We conducted qualitative interviews with all promotores starting the program, after 5 and 13 months. Three main themes emerged: 1) Men decided to become promotores to help others, yet appreciated being paid. 2) Promotores' learning experience was ongoing and was facilitated by a cooperative dynamic among them. Learning how to listen was crucial for promotores 3) Promotores experienced difficulty separating their personal lives form their role as a promotor We conclude that paying promotores facilitates the fulfillment of their drive to serve the community. Enhancing listening abilities needs to be part of promotores' training curricula. Finally, it is advisable to build a project with many opportunities for promotores and project staff to share professional and non-professional time and discuss their challenges. PMID:27102810

    It has been previously established that the BT type of cytoplasmic male sterility (CMS) is induced by high temperatures,while photosensitive genic male sterility (PGMS) seed sets by low temperatures induce. In the current study, we have bred photosensitive cytoplasmic male sterility (PCMS) lines (2308SA and 2310SA) by crossing the CMS line with the PGMS japonica line with maintainer genes. The sterility of PCMS japonica was consequently controlled by two groups of male sterile genes resulting from the integration of PGMS and CMS genes. The results on plant fertility, at different sowing times, were as follows: (a) Under conditions of natural long-day photoperiod and at temperatures above 35℃, the PGMS gene regulated PCMS japonica sterility - the higher the temperature, the lower the pollen fertility. However, bagged seed sets of PCMS japonica, not exposed to high temperatures, induced the CMS seed set. (b) Exposure to long-day photoperiod and temperature conditions between 35℃ and the critical sterility inducing temperature of PGMS resulted in both PGMS and CMS gene controlled sterility of PCMS japonica, which exhibited stable characteristics. (c) When exposed to critical sterility inducing temperatures or short-day photoperiod and daily high temperatures below 32℃, the BT type of the CMS gene regulated PCMS sterility. Under these conditions, the PGMS gene rendered male sterility insusceptible to occasional cool summer days when this PCMS line, adopted for hybrid seed production, develops into panicle differentiation stage.The present study also investigated the fertility restoration, seed production and combining ability of PCMS japonica so as to optimize its use.

  12. Measuring male infertility: epidemiological aspects

    2003-01-01

    Full Text Available Evidence suggests that human semen quality may have been deteriorating in recent years. Most of the evidence is retrospective, based on analysis of data sets collected for other purposes. Measures of male infertility are needed if we want to monitor the biological capacity for males to reproduce over time or between different populations. We also need these measures in analytical epidemiology if we want to identify risk indicators, risk factors, or even causes of an impaired male fecundity-that is, the male component in the biological ability to reproduce. The most direct evaluation of fecundity is to measure the time it takes to conceive. Since the time of conception may be missed in the case of an early abortion, time to get pregnant is often measured as the time it takes to obtain a conception that survives until a clinically recognized pregnancy or even a pregnancy that ends with a live born child occurs. A prolonged time required to produce pregnancy may therefore be due to a failure to conceive or a failure to maintain a pregnancy until clinical recognition. Studies that focus on quantitative changes in fecundity (that does not cause sterility should in principle be possible in a pregnancy sample. The most important limitation in fertility studies is that the design requires equal persistency in trying to become pregnant and rather similar fertility desires and family planning methods in the groups to be compared. This design is probably achievable in exposure studies that make comparisons with reasonable comparable groups concerning social conditions and use of contraceptive methods.

    Objective: To determine the leptin levels in the serum of normal, sub fertile and infertile men. Study Design: Analytical study. Place and Duration of Study: Department of Animal Sciences Quaid-e-Azam University, Islamabad, National Institute of Health (NIH), Islamabad and Dr. Salma and Kafeel Medical Centre, Islamabad, from April to December 2009. Methodology: Serum leptin levels hormonal concentrations (LH, FSH and testosterone) were determined by EIA in 154 males including 24 (15.58%) fertile, 19 (12.34%) polyzoospermic (PZs), 26 (16.88%) teratozoospermic (TZs), 27 (17.53%) astheno-teratozoospermic (ATZs), 18 (11.69%) oligozoospermic (OZs), 18 (11.69%) oligo-astheno-teratozoospermic (OATZs), 11 (7.14%) obstructive azoospermic (OBST-AZOOs) and 11 (7.14%) non-obstructive azoospermic (NON-OBST-AZOOs). BMI was also determined, divided into groups of greater than 24. Hormonal concentrations were compared by ANOVA and correlation was performed by using Graph pad prism version 5. Results: Significantly high levels of leptin concentrations were found in fertile (p 24 compared to fertile and infertile male patients with BMI 24. Leptin showed a significant positive correlation with LH (p < 0.01) and FSH (p < 0.002) and a significant negative correlation with testosterone (p < 0.001). Conclusion: Abnormal leptin level was significantly associated with fertility problems in males. Providing a link between leptin and reproduction factors contributing in control of testosterone and gonadotropins secretion in many aspects depending on fertility status in male subjects. BMI appears to have significant association with serum leptin levels. (author)

    For years,the management and treatment of male factor infertility has been ‘experience’ and not ‘evidence’ based.Although not evidence-based,current clinical practice involves extensive use of assisted reproductive techniques (ART).Where specific treatments are not indicated or have failed,ART have become popular adjunctive treatments for alleviating male factor infertility.According to the limited evidence available,intrauterine insemination (IUI) may be considered as a first-line treatment in a couple in which the female partner has a normal fertility status and at least 1x 106 progressively motile spermatozoa are recovered after sperm preparation.If no pregnancy is achieved after 3-6 cycles of IUI,optimized in vitro fertilization (IVF) can be proposed.When less than 0.5x 106 progressively motile spermatozoa are obtained after seminal fluid processing or sperm are recovered surgically from the testis or epididymis,intracytoplasmic sperm injection (ICSI) should be performed.Although the outcome of no other ART has ever been scrutinized as much before,no large-scale ‘macroproblems’ have as yet been observed after ICSI.Yet,ICSI candidates should be rigorously screened before embarking on IVF or ICSI,and thoroughly informed of the limitations of our knowledge on the hereditary aspects of male infertility and the safety aspects of ART.

  20. Male-mediated developmental toxicity

    International Nuclear Information System (INIS)

    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 F1 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 F1 male offspring. This suggests the endpoints are determined by independent genetic events. The results from heritable

    1985-10-01

    This study examined the relationships among homophobia, perceived fathering, and male intimacy with significant male and female best friends. A questionnaire, administered to 130 adult heterosexual males, included McDonald and Game's homophobia measure (ATHMS), eight intimacy scales, and four scales measuring subjects' recollections of their fathers' parenting styles. Correlations of ATHMS and individual intimacy scales revealed a significant relationship between homophobia and intimacy in male-male relationships. Homophobia was related to male-female intimacy on those measures which reflected subjects' perception of their female partner's sensitivity to them. Although homophobia was related to perception of the father as enforcing sex roles, none of the perceived fathering variables were directly related to intimacy with males. The findings provide evidence for a direct relationship between male homophobia and lack of intimacy in friendships between men. PMID:4067792

    Theory predicts that mate choice can lead to an increase in female fecundity if the secondary sexual traits used by females to assess male quality covary with the number of sperm transferred during copulation. Where females mate multiply, such a relationship between male attractiveness and ejaculate size may, additionally (or alternatively), serve to augment the effect of indirect selection by biasing paternity in favour of preferred males. In either case, a positive correlation between male ...

    Full Text Available Objective To investigate the therapeutic effect of autologous peripheral blood stem cell transplantation (APBSCT in combination with rituximab in treatment of CD20+ B cellulous non-Hodgkin's lymphoma (B-NHL. Methods Sixty patients with CD20+ aggressive or refractory and recurrent B-NHL and treated with APBSCT in our department from Jan. 2005 to Jan. 2011 were admitted. All the subjects were divided into 2 groups according to their own choice: 25 patients received rituximab treatment (treatment group and 35 patients were treated without rituximab treatment (control group. All patients underwent chemotherapy and APBSCT. For patients in treatment group, rituximab was used with CHOP before collecting the stem cells and after the transplantation. After transplantation, rituximab and IL-2 were used in treatment group every 3-6 months as maintenance treatment. Results No side effect was observed during the use of rituximab either before or after transplantation. The mononuclear cell count in treatment and control group was (8.2±2.9×108/kg and (8.4±3.9×108/kg (P=0.822, respectively; CD34+cell count was (12.3±12.7×106/kg and (13.2±13.9×106/kg (P=0.799, respectively. Haemopoiesis reconstruction was successfully achieved in the patients of treatment group, while 3 patients in control group failed to have haemopoiesis reconstruction. No significant difference was found between two groups on the recovery time of neutrophilic granulocytes and platelets. All patients achieved complete remission. The average follow-up time was 22 months. The disease relapsed in two patients in treatment group and six in control group. The 3-year overall survival rate in treatment group (91.6% was a little higher than that in control group (69.5%, P=0.060. Conclusion To patients of CD20+ B lymphoma, the use of rituximab shows no side effect before or after collection of stem cell and hemopoiesis reconstruction, and the overall survival rate may be improved.

    The poly(ADP-ribose)polymerase is a nuclear ubiquitous enzyme capable of binding to DNA breaks. Chinese hamster ovary cells were (CHO-K1) cultured on slides and γ-irradiated (137Cs) at a high (12.8 Gy/min) or medium dose rate (5 Gy/min), and immunolabelling against (ADP-ribose) polymers immediatly or three hours after irradiation. Quantification and localisation of γ-ray induced breaks was performed by confocal microscopy. The results show a dose effect relationship, a dose-rate effect and the signal disappearence after 3 hours at 37 °C. The presence of PARP activity appears to reflect γ-rays induced DNA fragmentation. Le poly(ADP-ribose)polymérase est une enzyme nucléaire ubiquitaire capable de se fixer sur les cassures de l'ADN. Sur une lignée sauvage de cellules d'ovaire de hamster chinois (CHO-K1) cultivée sur lame et irradiée aux rayons γ à haut débit de dose (HD) 12,8 Gy/min ou à moyen débit de dose (MD) 5 Gy/min, nous avons réalisé un immunomarquage anti-polymères d'ADP-ribose immédiatement après l'irradiation γ ou après trois heures d'incubation à 37 °C. La quantification et la localisation des lésions radioinduites ont été réalisées par microscopie confocale. Les résultats montrent une relation dose-effet et un effet de débit de dose, ainsi qu'une disparition du signal après 3 heures à 37 °C. La présence de la PARP semble donc bien refléter la fragmentation radioinduite de l'ADN.

    Full Text Available 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.

    Infanticide by primate males was considered rare if groups contain more than one adult male because, owing to lower paternity certainty, a male should be less likely to benefit from infanticide. Guided by recent evidence for strong variation of infanticide in primate multi-male groups, we modelled the conditions for when infanticide should occur for a group with a resident and an immigrant male. Setting the parameters (e.g. infant mortality, reduction of interbirth interval, life-time reprodu...

    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 wa...

    2005-01-01

    Breast cancer in men is a rare disease, accounting for approximately 1% of all breast cancer cases. Although the epidemiologic literature regarding female breast cancer is extensive, relatively little is known about the etiology of male breast cancer (MBC). This review is intended to summarize the existing body of evidence on genetic and epidemiologic risk factors for breast cancer in men. Overall, the epidemiology of MBC presents similarities with the epidemiology of female breast cancer. Major genetic factors associated with an increased risk of breast cancer for men include BRCA2 mutations, which are believed to account for the majority of inherited breast cancer in men, Klinefelter syndrome, and a positive family history. Suspected genetic factors include AR gene mutations, CYP17 polymorphism, Cowden syndrome, and CHEK2. Epidemiologic risk factors for MBC include disorders relating to hormonal imbalances, such as obesity, testicular disorders (e.g., cryptorchidism, mumps orchitis, and orchiectomy), and radiation exposure. Suspected epidemiologic risk factors include prostate cancer,prostate cancer treatment, gynecomastia, occupational exposures (e.g., electromagnetic fields, polycyclic aromatic hydrocarbons, and high temperatures), dietary factors (e.g., meat intake and fruit and vegetable consumption), and alcohol intake.

    The role of androgens in cardiovascular disease is still controversial in men. In this study, we investigated metabolic disorders in Tunisian hypogonadal men compared with healthy controls. Forty hypogonadal men and 80 control subjects were enrolled. Patients with a history of pre-existing panhypopituitarism, thyroid dysfunction or inflammatory disease were excluded. Glycaemia, glycated haemoglobin (HbA1c), high-sensitive C-reactive protein (hsCRP), lipid profile, insulin, testosterone and gonadotrophins were measured. Insulin resistance was assessed by homoeostasis model assessment of insulin resistance (Homa IR). Waist circumference, body mass index and blood pressure were significantly higher in patients compared with controls. Glycemia, HbA1c, fasting serum insulin and Homa IR were significantly increased among hypogonadal men. In univariate analysis, testosterone levels were inversely correlated with body mass index, waist circumference, blood pressure, glycaemia, HbA1C, insulin, Homa IR and hsCRP. In multivariate analysis including all significant variables, initial testosterone level was the only independent risk factor for developing dyslipidaemia. With logistic regression, male hypogonadism was an independent risk factor for MS (P < 0.001). We conclude that low testosterone level plays a central role in the development of metabolic syndrome. Further prospective data are required to establish the causative link. PMID:25040289

  2. Hypogonadism in male cancer patients.

    2012-09-01

    Prevalence of hypogonadism in men with cancer has been reported between 40% and 90%, which is significantly higher than in the general population. Hypogonadism is likely to affect the quality of life in these patients by contributing to non-specific symptoms, including decreased energy, anorexia, sarcopenia, weight loss, depression, insomnia, fatigue, weakness, and sexual dysfunction. Pathogenesis of hypogonadism in cancer patients is thought to be multi-factorial. Inflammation may play an important role, but leptin, opioids, ghrelin, and high-dose chemotherapy through different mechanisms have all been implicated as the cause. Hypogonadism is also associated with poor survival in cancer patients. Data looking into the treatment of hypogonadal male cancer patients with testosterone are limited. However, improvements in body weight, muscle strength, lean body mass, and quality of life have been shown in hypogonadal men with other chronic diseases on testosterone replacement therapy. Prospective and interventional trials are needed to test the efficacy and safety of testosterone treatment in improving quality of life of these patients. PMID:22528986

    Although homosexual activity is prevalent among US teenagers, adolescent homosexuality per se has been a poorly understood phenomenon. The purpose of this investigation is to describe the meaning and experience of homosexuality from the adolescent's perspective. Twenty-nine male teenagers, self-described as gay (79%) or bisexual (21%), volunteered to participate in a structured interview, the purpose of which was to examine the definition of homosexuality, the acquisition of a gay identity, and the impact of sexuality on family, peers, and community. The youths demonstrated well-established sexual identities by the consistency of their sexual fantasies, interests, and behaviors over time. Homosexuality was more frequently described as a general attraction to men (48%) and an indicator of positive personal attributes (33%) than as an isolated sexual behavior. The subjects reported strong negative attitudes from parents (43%) and friends (41%) toward their sexualities. Discrimination (37%), verbal abuse from peers (55%), and physical assaults (30%) were frequently cited problems. These stressors may place the boys at high risk for physical and psychosocial dysfunction. PMID:3822631

    Full Text Available 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.

    Summary In sexually reproducing animals, male and female reproductive strategies often conflict [1]. In some species, males use aggression to overcome female choice [2, 3], but debate persists over the extent to which this strategy is successful. Previous studies of male aggression toward females among wild chimpanzees have yielded contradictory results about the relationship between aggression and mating behavior [4-11]. Critically, however, copulation frequency in primates is not always predictive of reproductive success [12]. We analyzed a 17-year sample of behavioral and genetic data from the Kasekela chimpanzee (Pan troglodytes schweinfurthii) community in Gombe National Park, Tanzania, to test the hypothesis that male aggression toward females increases male reproductive success. We examined the effect of male aggression toward females during ovarian cycling, including periods when the females were sexually receptive (swollen) and periods when they were not. We found that, after controlling for confounding factors, male aggression during a female’s swollen periods was positively correlated with copulation frequency. However, aggression toward swollen females was not predictive of paternity. Instead, aggression by high-ranking males toward females during their nonswollen periods was positively associated with likelihood of paternity. This indicates that long-term patterns of intimidation allow high-ranking males to increase their reproductive success, supporting the sexual coercion hypothesis. To our knowledge, this is the first study to present genetic evidence of sexual coercion as an adaptive strategy in a social mammal. PMID:25454788

  12. Sexy faces in a male paper wasp.

    Directory of Open Access Journals (Sweden)

    André Rodrigues de Souza

    Full Text Available 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.

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.

    Full Text Available Abstract Introduction Male monogyny in the absence of paternal investment is arguably one of the most puzzling mating systems. Recent evidence suggests that males of monogynous species adjust their life-history and their mating decision to shifting spatial and temporal selection regimes. In the cannibalistic wasp spider Argiope bruennichi males can be either monogynous or mate with a maximum of two females. We studied factors underlying male mating decisions in a natural population over a whole mating season. We documented all matings and categorized the males into single-mated and double-mated monogynous as well as bigynous males. Results We found that all categories were continuously present with relatively stable frequencies despite changes in the operational sex ratio. Males were more likely monogynous when copulating with relatively heavy and old females and otherwise bigynous. Conclusion Our results imply that males make conditional mating decisions based on the quality of the first female they encounter but do not adjust their mating tactic to the local selection regime.

  5. A high aggression strategy for smaller males.

    Directory of Open Access Journals (Sweden)

    P Andreas Svensson

    Full Text Available Male-male conflict is common among animals, but questions remain as to when, how and by whom aggression should be initiated. Factors that affect agonistic strategies include residency, the value of the contested resource and the fighting ability of the two contestants. We quantified initiation of aggression in a fish, the desert goby, Chlamydogobius eremius, by exposing nest-holding males to a male intruder. The perceived value of the resource (the nest was manipulated by exposing half of the residents to sexually receptive females for two days before the trial. Resident male aggression, however, was unaffected by perceived mating opportunities. It was also unaffected by the absolute and relative size of the intruder. Instead resident aggression was negatively related to resident male size. In particular, smaller residents attacked sooner and with greater intensity compared to larger residents. These results suggest that resident desert goby males used set, rather than conditional, strategies for initiating aggression. If intruders are more likely to flee than retaliate, small males may benefit from attacking intruders before these have had an opportunity to assess the resident and/or the resource.

  11. Male skin care: shaving and moisturization needs.

    Oblong, John E

    2012-01-01

    Historically, most cosmetic and medical cosmetic research has been focused on the female consumer. Advancements in the development of grooming instruments as well as changing consumer habits and attitudes toward male cosmetic skin care needs support the need to develop a deeper understanding of male skin biology and how that can be used to improve the quality of life relative to societal interactions. Male skin biology has been found to have unique properties that are distinct from females and have a significant impact on the way males groom and maintain their overall appearance. Research to date has found that male skin has a different response profile to such environmental insults as UV, heat, and stress that is based not on just differences in cosmetic or dermatological product usage but also on underlying biological differences. These differences are discussed with the implications to a broader understanding of male facial skin care needs that spans from daily grooming practices to overall health status that impacts higher incidence rate of skin cancer among males. This highlights that male skin care has a holistic need to ensure proper grooming and sunscreen moisturizer usage. PMID:22913441

  12. Male Infertility and Its Causes in Human

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Infertility is one of the most serious social problems facing advanced nations. In general, approximate half of all cases of infertility are caused by factors related to the male partner. To date, various treatments have been developed for male infertility and are steadily producing results. However, there is no effective treatment for patients with nonobstructive azoospermia, in which there is an absence of mature sperm in the testes. Although evidence suggests that many patients with male infertility have a genetic predisposition to the condition, the cause has not been elucidated in the vast majority of cases. This paper discusses the environmental factors considered likely to be involved in male infertility and the genes that have been clearly shown to be involved in male infertility in humans, including our recent findings.

  13. Ocean acidification changes the male fitness landscape

    2016-01-01

    Sperm competition is extremely common in many ecologically important marine taxa. Ocean acidification (OA) is driving rapid changes to the marine environments in which freely spawned sperm operate, yet the consequences of OA on sperm performance are poorly understood in the context of sperm competition. Here, we investigated the impacts of OA (+1000 μatm pCO2) on sperm competitiveness for the sea urchin Paracentrotus lividus. Males with faster sperm had greater competitive fertilisation success in both seawater conditions. Similarly, males with more motile sperm had greater sperm competitiveness, but only under current pCO2 levels. Under OA the strength of this association was significantly reduced and there were male sperm performance rank changes under OA, such that the best males in current conditions are not necessarily best under OA. Therefore OA will likely change the male fitness landscape, providing a mechanism by which environmental change alters the genetic landscape of marine species. PMID:27531458

  16. Anorexia nervosa and bulimia in adolescent males.

    Science.gov (United States)

    Andersen, A E

    1984-12-01

    Anorexia nervosa or bulimia in adolescent males occurs ten times less frequently than in adolescent females. When they occur, however, they can be clearly identified and differentiated from disorders also associated with weight loss such as swallowing phobias. Early diagnosis and treatment leads to improved outcome. While the formal psychopathology of male anorectics is similar to that of females, there is often a different motivation for the initial weight loss in males. They are more often concerned with attaining an idealized male body and avoiding teasing or criticism about their appearance. When males become ill, they tend to develop the full anorectic syndrome or not to become ill at all. Recognition of the special needs of adolescent males for individualized treatment increases the change of optimal outcome. Anorexia nervosa and bulimia in the teenage male should be seen as an ineffective method of dealing with developmental crises by gaining a sense of effectiveness and control through weight reduction and food restriction. Treatment seeks to improve quickly the starvation-related aspects of the illness while attempting to find more appropriate methods of dealing with the life crises prompting the illness. The real goal of treatment is to make the anorectic or bulimic illness unnecessary by encouraging the patient to continue the work of individuation and separation so that challenges in development and problems in living are resolved in a direct rather than an indirect way through an eating disorder.

    2008-01-01

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

    Oliva, Clelia F; Damiens, David; Benedict, Mark Q

    2014-04-01

    Among Aedes mosquitoes are species responsible for transmission of serious pathogens to humans. To cope with the current threats to long-term effectiveness of the traditional vector control methods, non-conventional control strategies are being developed. These include autocidal control such as the release of sterile males (sterile insect technique) and the release of Wolbachia-infected males to induce sexual sterility (incompatible insect technique) and pathogen-refractory strain replacement variations using Wolbachia. Sterile male types of techniques particularly depend on released males' ability to successfully mate with wild females. For that reason, a good understanding of male mating biology, including a thorough understanding of the reproductive system and mating capacity, increases the likelihood of success of such genetic vector control programmes. Here we review the literature concerning the reproduction of Aedes mosquitoes with an emphasis on the male biology. We consider sexual maturation, mate finding, insemination, male reproductive capacity, and the occurrence of multiple matings. We also discuss which parameters are of greatest importance for the successful implementation of autocidal control methods and propose questions for future research. PMID:24308996

    Full Text Available In humans, naturally acquired microchimerism has been observed in many tissues and organs. Fetal microchimerism, however, has not been investigated in the human brain. Microchimerism of fetal as well as maternal origin has recently been reported in the mouse brain. In this study, we quantified male DNA in the human female brain as a marker for microchimerism of fetal origin (i.e. acquisition of male DNA by a woman while bearing a male fetus. Targeting the Y-chromosome-specific DYS14 gene, we performed real-time quantitative PCR in autopsied brain from women without clinical or pathologic evidence of neurologic disease (n=26, or women who had Alzheimer's disease (n=33. We report that 63% of the females (37 of 59 tested harbored male microchimerism in the brain. Male microchimerism was present in multiple brain regions. Results also suggested lower prevalence (p=0.03 and concentration (p=0.06 of male microchimerism in the brains of women with Alzheimer's disease than the brains of women without neurologic disease. In conclusion, male microchimerism is frequent and widely distributed in the human female brain.

  1. Primate Socioecology: New Insights from Males

    Science.gov (United States)

    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.

  2. Conflict over Male Parentage in Social Insects

    2004-01-01

    Full Text Available 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.

  3. Sneaker "jack" males outcompete dominant "hooknose" males under sperm competition in Chinook salmon (Oncorhynchus tshawytscha).

    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.

    Most seasonally reproducing vertebrates show pronounced changes in testosterone levels throughout the year. The Challenge Hypothesis [Wingfield, J.C., Hegner, R.E., Dufty, A.M., Ball, G. F., 1990. The "challenge hypothesis": theoretical implications for patterns of testosterone secretion, mating systems, and breeding strategies. Am. Nat. 136, 829-846] predicts that seasonal patterns in circulating androgen concentrations vary as a function of mating system, male-male aggression and paternal care. In most comparative studies, the predictions of the Challenge Hypothesis have been tested primarily by calculating the ratio between breeding peak and breeding baseline testosterone concentrations, using this ratio as a proxy for the effect that social interactions have on testosterone levels (androgen responsiveness R). Recently, we suggested that it is preferable to separate the seasonal testosterone response (R(season)) from the androgen responsiveness to male-male interactions (R(male-male)), as these two measures do not correlate and can differ both in magnitude and direction [Goymann, W., Landys, M.M., Wingfield, J.C., 2007. Distinguishing seasonal androgen responses from male-male androgen responsiveness-revisiting the Challenge Hypothesis. Horm. Behav. 51, 463-476]. Here, I discuss several methodological and ecological factors that may explain why R(season) and R(male-male) differ. Furthermore, I describe three other kinds of androgen responsiveness, namely the androgen responsiveness of males to receptive females (R(male-female)), to non-social environmental cues (R(environment)), and the potential androgen responsiveness (R(potential)). The latter is measured before and after an injection of gonadotropin releasing hormone (GnRH), which typically leads to a maximal release of testosterone from the testes. I argue that separation of different kinds of androgen responsiveness and putting them into context with the natural history and ecology of a study species may

    Effective regulation of human fertility has global consequences in terms of resource depletion, pollution and poverty. Current family planning services predominantly target a female clientele with few significant developments in male fertility regulation for over a century. The last two decades have witnessed a gathering interest, initially from the scientific community, and laterally from industry, in the development of safe, reliable, reversible methods of contraception for men. This review summarises the methods of male fertility regulation which are currently available and critically examines the published data on novel developments in male hormonal contraception which offer the potential of improved contraceptive choice for all in new millennium.

  9. God as Father: The maleness of God

    Directory of Open Access Journals (Sweden)

    D. T. Williams

    1990-03-01

    Full Text Available It is fashionable today to try to avoid sexist language in theology, despite the Bible’s consistent use of the masculine pronoun when referring to God. Although such an attempt has largely been engendered by modem culture, the maleness of God is not simply a hangover from a patriarchal society, but reflects a fundamental maleness in God’s dealing with man. It emphasises the idea of redemption by grace alone over against creation, and such aspects as the adoption of Christians as sons. The maleness of Christ likewise has not simply been cultural, but is significant theologically. This is not to deny any femininity in God, but to assert that male features predominate. Such an idea does not reduce the status of women, but rather an emphasis on redemption raises it. Raising the status of women in society would in fact reduce the pressure to demasculinize God.

    Selenium concentration in the sera and seminal plasma of 60 infertile males (40 oligospermia and 20 azoospermia) and 40 males with proven evidence of fertility (normospermia; control group) were estimated using atomic absorption spectrophotometry. Results were correlated with spermatogram and hormonal levels in order to determine their relationship and significance in male infertility. The mean serum concentrations of selenium was found to be significantly increased in oligospermic compared to azoospermic subjects and controls (p physiological balance in the distribution of selenium in serum and seminal plasma compartment of control males. A disturbance in this balance has a significant influence on spermatogenesis. Selenium appears to have a positive influence on Leydig cells, thus influencing the secretion of testosterone.

    Full Text Available Unexplained male infertility is a diagnosis reserved for men in whom routine semen analyses results are within normal values and physical as well as endocrine abnormalities were ruled out. In addition to erectile problems and coital factors, immunologic causes and sperm dysfunction may contribute to such condition. New etiologies of unexplained male infertility include low level leukocytospermia and mitochondrial DNA polymerase gene polymorphism. Contemporary andrology may reveal cellular and sub-cellular sperm dysfunctions which may explain subfertility in such cases, thus aiding the clinician to direct the further work-up, diagnosis and counseling of the infertile male. The objective of this article is to highlight the concept of unexplained male infertility and focuses on the diagnosis and treatment of this condition in the era of modern andrology and assisted reproductive techniques. Extensive literature review was performed using the search engines: Pubmed, Science-direct, Ovid and Scopus.

    Full Text Available Abstract Background The overall incidence of male breast cancer is around 1% of all breast cancers and is on the rise. In this review we aim to present various aspects of male breast cancer with particular emphasis on incidence, risk factors, patho-physiology, treatment, prognostic factors, and outcome. Methods Information on all aspects of male breast cancer was gathered from available relevant literature on male breast cancer from the MEDLINE database over the past 32 years from 1975 to 2007. Various reported studies were scrutinized for emerging evidence. Incidence data were also obtained from the IARC, Cancer Mondial database. Conclusion There is a scenario of rising incidence, particularly in urban US, Canada and UK. Even though more data on risk factors is emerging about this disease, more multi-institutional efforts to pool data with large randomized trials to show treatment and survival benefits are needed to support the existing vast emerging knowledge about the disease.

    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...

    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 ...

    Exocrine gland-secreting peptide 1 (ESP1) released into male tear fluids is a male pheromone that stimulates sexually receptive behavior in female mice via the vomeronasal sensory system. ESP1 also induces c-Fos expression in male brain regions distinct from those in females. However, behavior in males following ESP1 exposure has not been examined. In the present study, we show that ESP1, in conjunction with unfamiliar male urine, enhances male aggression via the specific vomeronasal receptor V2Rp5. In addition, male mice that secrete ESP1 but lack V2Rp5 exhibit a lower level of aggressiveness than do mice that express V2Rp5. These results suggest that ESP1 not only acts as a male pheromone in both sexes but also serves as an auto-stimulatory factor that enhances male aggressiveness by self-exposure. Finally, re-activation of ESP1-induced c-Fos-positive neurons by using the designer receptor exclusively activated by designer drug (DREADD) approach resulted in enhancement of sexual and aggressive behaviors in female and male mice, respectively, indicating that sexually dimorphic activation in the brain is a neural basis for the sex-specific behavioral responses to ESP1.

    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

  6. Genetic Studies on Wheat Genic Male Sterility and Inheritance Mode of Male Sterility in Plant

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    Advance in the genetic study on male sterility in plant was reviewed. A dominant gene Ms2(Ta1) for male sterility, which hasa recombination percentage of 31. 16 with the centromere , is located on the short arm of chromosome 4D in Taigu wheat. Dwarfing male sterile wheat is a dwarf marked male sterile material, carrying the gene Ms2 for male sterility and dominant dwarf gene Rht10. The two genes, Ms2 and Rht10, are closely linked with a crossing-over value as small as 0. 18. The linkage character of genes Ms2 and Rht10 was transferred to CS ph1b mutant and octoploid triticale. A female-male sterility controlled by a set of genes and a male sterility carrying double recessive genes were discovered in wheat. The hypothesis of the origin of the male sterile form for gene interaction was proposed. An inheritance mode of fertility in sib-mating progenies of reces sive genic male sterile material in plant was established.

    Cytoplasmic male sterility (cms) is determined by nuclear-cytoplasmic interactions. Up tonow, most studies are focused on the comparison of cytoplasmic DNAs of male-sterile lines and male-fertilelines, and analysis of nuclear DNA has not been documented yet. In order to find out the possible difference innuclear genome of male-sterile line A1 Tx623 and corresponding male-fertile line Tx623 of sorghum, randomamplified polymorphic DNA (RAPD) approach was used to analyze their cytoplasmic and nuclear genomes.Total DNAs of them were amplified at first to screen primers, which were able to generate reproducible bandsspecific to male-sterile line or male-fertile line. Then the selected primers were used to amplify their mitochon-drial DNA (mtDNA) and chloroplast DNA (cpDNA). The origins of all the polymorphic fragments were ana-lyzed. After ruling out those amplified from cytoplasmic DNA, seventeen polymorphic fragments were deter-mined to be amplified from nuclear DNA. These fragments originated from nuclear DNA indicate that diffe-rences in sequence exist between the nuclear DNA of male-sterile line and male-fertile line of sorghum, whichdo not agree with the traditional standpoint that they have identical nucleus.

    Full Text Available 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.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: 52.8 m (95% CI: 49.9 m, 56.8 m and Malaysia: 58.0 m (95% CI: 51.1 m, 71.0 m.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.

    Full Text Available Aim: Halitosis is an unpleasant alteration of the halitus. The aim of the study is to assess the quality of sexual life of males with and without halitosis. Material and Method: Males between 20-50 years old; with a complaint of halitosis; married and able to complete the study were included in the study. The control group were healthy, adult, married males who have normal otorhinolaryngologic examination. The International Index of Erectile Function questionnaire(IIEF were used to assess the quality of sexual life  of males with halitosis and the results were compared with a similar group of healthy men. Results: A total of 80 adult subjects completed the study. When the groups were compared in terms of age, body mass index(BMI and duration of marriage, they were similar (p=0.65, p= 0.20, p= 0.08 respectively.The halitosis group had significantly lower scores for all function domains (p=0.0001.There was no correlation between degree of halitosis and the scores of IIEF (p< 0.05. Discussion: This is the first study investigating the sexual health of males with halitosis. Halitosis not only effects oral health status but also strongly declines quality of life. The otorhinolaryngologist must not only treat halitosis but also help the patient to stand up to social and sexual problems concomitting halitosis.

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

    Previous research on nonconscious mimicry suggests that females mimic their communication partners more often than males. Many studies have investigated the association between mimicry, emotion recognition, and empathy. However, there is a trend in this research area to recruit same-sex samples......, thus neglecting a discussion regarding the role of sex or gender as a moderator of nonconscious mimicry. This article reviews the research on nonconscious mimicry – facial, behavioural, and verbal, in order to identify whether or not there are male and female differences. The results indicate that...... mimicry may be moderated by participant sex or gender depending upon, among others, choice of mimicry measurement, stimulus exposure length, and social context. However, few studies address male and female differences in mimicry and many have methodological limitations. The review concludes with a...

    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.

    The preservation of reproductive health of the population is an important factor of demographic policy of the state. According to some authors from 14 to 30% of couples of reproductive age suffer from infertility, malefactor in such marriages is detected in more than half of the cases. As you know, in recent years there has been a significant deterioration in the main indicators of reproductive function of men. Increased the number of andrological diseases, morphological disorders of the male reproductive system, almost halved the production of sperm in men of reproductive age. The reason probably lies behind a whole range ofstressfactors, such as medical ignorance, uncontrolled and inappropriate use of medication, metabolic disturbances, lack of vitamins and minerals, the impact of industrial pollutants, as well as the growth of addictive disorders (alcoholism, smoking and drug addiction). The forms of infertility differ according to its etiology and severity from minor changes to complete spermatogenesis dysfunction of the gonads, and can also occur due to genetic disorders. The lack of analysis of the relationship between clinical and genetic-biochemical components in men with infertility makes it impossible to understand the pathogenesis of infertility and to assess the risks of male infertility. High level of current medicine does not always guarantee an identification of the cause of male infertility. The article analyzes data from the review of specialized literature on the diagnosis and etiopathogenesis of male infertility. Frequency and clinical signs of pathology of the male reproductive system depend on the combinatorial effects of environmental influences, manifested most often in mutually reinforcing effect. A combination of several, seemed to be imperceptible factors makes the risk of development of male reproductive pathology very high. This situation compels specialists to conduct comprehensive studies on the men reproductive potential. PMID

  16. The importance of female choice, male-male competition, and signal transmission as causes of selection on male mating signals.

    Sullivan-Beckers, Laura; Cocroft, Reginald B

    2010-11-01

    Selection on advertisement signals arises from interacting sources including female choice, male-male competition, and the communication channel (i.e., the signaling environment). To identify the contribution of individual sources of selection, we used previously quantified relationships between signal traits and each putative source to predict relationships between signal variation and fitness in Enchenopa binotata treehoppers (Hemiptera: Membracidae). We then measured phenotypic selection on signals and compared predicted and realized relationships between signal traits and mating success. We recorded male signals, then measured lifetime mating success at two population densities in a realistic environment in which sources of selection could interact. We identified which sources best predicted the relationship between signal variation and mating success using a multiple regression approach. All signal traits were under selection in at least one of the two breeding seasons measured, and in some cases selection was variable between years. Female preference was the strongest source of selection shaping male signals. The E. binotata species complex is a model of ecological speciation initiated by host shifts. Signal and preference divergence contribute to behavioral isolation within the complex, and the finding that female mate preferences drive signal evolution suggests that speciation in this group results from both ecological divergence and sexual selection.

    Existing theory predicts that male signalling can be an unreliable indicator of paternal care, but assumes that males with high levels of mating success can have high current reproductive success, without providing any parental care. As a result, this theory does not hold for the many species where offspring survival depends on male parental care. We modelled male allocation of resources between advertisement and care for species with male care where males vary in quality, and the effect of c...

    It is fashionable today to try to avoid sexist language in theology, despite the Bible’s consistent use of the masculine pronoun when referring to God. Although such an attempt has largely been engendered by modem culture, the maleness of God is not simply a hangover from a patriarchal society, but reflects a fundamental maleness in God’s dealing with man. It emphasises the idea of redemption by grace alone over against creation, and such aspects as the adoption of Christians as sons. The mal...

    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

    Full Text Available Research has established the principle of hormonal male contraception based on suppression of gonadotropins and spermatogenesis. All hormonal male contraceptives use testosterone, but only in East Asian men can testosterone alone suppress spermatogenesis to a level compatible with contraceptive protection. In Caucasians, additional agents are required of which progestins are favored. Clinical trials concentrate on testosterone combined with norethisterone, desogestrel, etonogestrel or depot-medroxyprogesterone acetate. The first randomized, placebo-controlled clinical trial performed by the pharmaceutical industry demonstrated the effectiveness of a combination of testosterone undecanoate and etonogestrel in suppressing spermatogenesis in volunteers.

  4. Distinguishing seasonal androgen responses from male-male androgen responsiveness-revisiting the Challenge Hypothesis.

    Goymann, Wolfgang; Landys, Meta M; Wingfield, John C

    2007-04-01

    Androgen levels show strong patterns throughout the year in male vertebrates and play an important role in the seasonal modulation of the frequency, intensity and persistence of aggression. The Challenge Hypothesis (Wingfield, J.C., Hegner, R.E., Dufty, A.M., Ball, G.F., 1990. The "Challenge Hypothesis": Theoretical implications for patterns of testosterone secretion, mating systems, and breeding strategies. Am. Nat. 136, 829-846) predicts that seasonal patterns in androgen levels vary as a function of mating system, male-male aggression and paternal care. Although many studies have addressed these predictions, investigators have often assumed that the ratio of the breeding season maximum and breeding baseline concentrations (termed "androgen responsiveness") reflects hormonal responses due to social stimulation. However, increasing evidence suggests that seasonal androgen elevations are not necessarily caused by social interactions between males. Here, we separate the seasonal androgen response (R(seasonal)) and the androgen responsiveness to male-male competition (R(male-male)) to begin to distinguish between different kinds of hormonal responses. We demonstrate that R(seasonal) and R(male-male) are fundamentally different and should be treated as separate variables. Differences are particularly evident in single-brooded male birds that show no increase in plasma androgen levels during simulated territorial intrusions (STIs), even though R(seasonal) is elevated. In multiple-brooded species, STIs typically elicit a rise in androgens. We relate these findings to the natural history of single- and multiple-brooded species and suggest a research approach that could be utilized to increase our understanding of the factors that determine different types of androgen responses. This approach does not only include R(seasonal) and R(male-male), but also the androgen responsiveness to receptive females (R(male-female)) and to non-social environmental cues (R

    The aim of this article is to discuss critical issues in treating males with eating disorders, and to present assessment and treatment outcome data for 111 males who received residential treatment for moderate to severe eating disorders. Males with eating disorders are often not included in eating disorder research as the population of individuals with eating disorders has historically been predominantly female. Whether this is due to actual lower prevalence of this disorder among males or to fewer males seeking treatment is not clear. In any case, there is limited empirical research on the particular treatment issues of males, and in treatment environments males are frequently in the minority. We have found that an all-male treatment environment is helpful in allowing males to benefit from treatment with less stigma. Data are presented which characterize psychiatric co-morbidity, excessive exercise, body image, sexuality, and spirituality in males. Treatment outcomes for males in this environment are positive.

    A consistent conclusion within the extant literature is that victimization and in particular polyvictimization leads to adverse mental health outcomes. A large body of literature exists as it pertains to the association between victimisation and mental health in studies utilising samples of childhood victims, female only victims, and samples of male and female victims; less research exists as it relates to males victims of interpersonal violence. The aim of the current study was therefore to identify profiles of interpersonal victimizations in an exclusively male sample and to assess their differential impact on a number of adverse mental health outcomes. Using data from 14,477 adult males from Wave 2 of the NESARC, we identified interpersonal victimization profiles via Latent Class Analysis. Multinomial Logistic Regression was subsequently utilized to establish risk across mental health disorders. A 4-class solution was optimal. Victimisation profiles showed elevated odds ratios for the presence of mental health disorders; suggesting that multiple life-course victimisation typologies exists, and that victimization is strongly associated with psychopathology. Several additional notable findings are discussed. PMID:27130979

    Full Text Available Sam ShusterNewcastle University, Newcastle Upon Type, NE1 7RU, UKAbstract: The response to seeing a man riding a unicycle was reported to be consistently related to the viewer's sex and stage of physical development. To see if this observation was universal, observations of responses were collected from 23 male and 9 female unicyclists aged 15–69 years, with 2–40 years cycling experience across four continents. With two exceptions among men, the findings were the same as those originally reported: children showed interest and curiosity, young girls showed little interest, while adult women showed a kindly, concerned, praising response. By contrast, boys showed physical aggression, which became more verbal, merging in the later teens to the snide, aggressive, stereotyped humorous response shown by adult males, which became less frequent in elderly men. The universality of the response across different individuals, environments, and dates of observation suggests an endogenous mechanism, and the association with masculine development relates this to androgen. The theoretical consequences are discussed. It is concluded that humor develops from aggression in males and is evolutionarily related to sexual selection.Keywords: humor evolution, male aggressive behavior

It was proved to influence woman's behaviour and mental functioning as well as that of a man. Cyclic changes throughout the menstrual cycle in women are known. To search for the infradian variations of human male testosterone levels in a follow up study, which was held in autumn 1999 (one month of continuous sampling) and in autumn 2000 (two and a half months of continuous sampling). Testosterone was determined in saliva, which contains biologically active fraction, unbound to proteins. In autumn 2000 sampling of 31 males (mean age 21.3 ± 1.3) collected saliva in the morning 30 minutes after waking-up every second day during one month and every third day during the following 6 weeks. Saliva was deeply frozen and analyzed by radioimmunoassay. Data of our preliminary study (based on samples collected in 1999) indicated circatrigintan variations of male salivary testosterone. By the use of two different methods (zones of minimum-moving averages and analysis of variance) circatrigintan and circavigintan cycles of salivary testosterone were found in the collected data of our subjects. The article considerates clinical applications of variation of hormonal levels. (authors)

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

  17. The Male Predominance in Esophageal Adenocarcinoma.

    2016-03-01

    The incidence of esophageal adenocarcinoma (EAC) has increased rapidly during the past 4 decades in many Western populations, including North America and Europe. The established etiological factors for EAC include gastroesophageal reflux and obesity, Helicobacter pylori infection, tobacco smoking, and consumption of fruit and vegetables. There is a marked male predominance of EAC with a male-to-female ratio in incidence of up to 9:1. This review evaluates the available literature on the reasons for the male predominance, particularly an update on epidemiologic evidence from human studies during the past decade. The striking sex difference does not seem to be explained by established risk factors, given that the prevalence of the etiological factors and the strengths of associations between these factors and EAC risk are similar between the sexes. Sex hormonal factors may play a role in the development of EAC; estrogenic exposures may prevent such development, whereas androgens might increase the risk of EAC. However, continuing research efforts are still needed to fully understand the reasons for the male predominance of EAC. PMID:26484704

  18. Epidemiologic methods for investigating male fecundity

    Directory of Open Access Journals (Sweden)

    2014-02-01

    Full Text Available 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.

  7. Relationship between blood groups and male infertility

    International Nuclear Information System (INIS)

    Background: Blood is man's complete and unchangeable identity. The ABO and Rh groups are recognised as major and clinically significant blood groups. Blood group antigens are not only important in relation to blood transfusion and organ transplantation, but also have been utilised in genetic research, anthropology and tracing ancestral relation of humans. The objective the present study is to examine the blood group antigens in infertile men for assessing the relationship to male infertility and to know the frequency of various blood groups among infertile males in our population. Method: A total of 1,521 patients along with 460 proven fathers as controls were recruited for the present study from both rural and urban areas of Pakistan and referred to Department of Reproductive Physiology/Health, Public Health Divisions, NIH, Islamabad, during 2002 to 2006. Blood grouping (ABO) and Rhesus factors (Rh) was done by the antigen antibody agglutination test. Results: Overall distribution of blood groups in the studied population of 1,521 subjects was 35.50%, 28.27%, 26.89% and 9.34% for blood groups O, B, A and AB respectively. The ratio of control to patient was 1:3.3. Conclusions: The present preliminary study revealed that in our population the prevalence of male infertility in blood group O is invariably higher than in all other ABO blood groups, showing a strong relationship between blood group O and male infertility.

  12. Utilization of male sterility in forage crops

    International Nuclear Information System (INIS)

    The genetic nature of male sterility in forage crops was reviewed. Many workers have suggested that hybrids in forage crops are quite promising. First, the selection of the most desirable parental genotype from a large original population is improtant in heterosis breeding programs. After the more promising inbreds or clones have been selected on the basis of good general combining ability, it is necessary to identify the particular single, three-way or double cross that will produce the highest yields. A high seed yield potential is also important in a new variety so that the seeds can be sold at lower prices than other varieties. A tentative scheme for hybrid seed production by using inbred lines of male sterile or normal parents is proposed. At a breeding station, the seeds for male sterile F1(AB), maintainer S1(C-S1) and either maintainer or restorer S1s(D-S1, E-S1) are produced from the parental clones. At a seed increase agency, the seeds for male sterile F1(ABC) and either maintainer or restorer S2(D-S2) are produced. In the case that D-S2 seed production is difficult, maintainer or restorer F1(DE) should be produced from D-S1 x E-S1. These seeds are used for commercial seed production. Seeds of hybrid F1(ABCD) or hybrid F1(ABCDE) are for practical use. (Kaihara, S.)

  13. Induced mutant for male sterility in niger

    Full text: Niger (Guizotia abyssinica Cass.), an important oilseed crop of the family Compositae is highly cross-pollinated due to the twin mechanisms of protandry and incompatibility. Studies revealed the functional nature of protandry and the breakdown of incompatibility with alteration in temperature. It has very small flowers (disc florets) arranged in a capitulum that open on 3-4 consecutive days which pose problems in emasculation for cross-breeding. To induce mutations, seeds of variety 'IGP-76' were irradiated with γ-rays 200 to 1000 Gy. All seeds of M1 plants were sown separately in individual plant-to progeny rows. The results of screening of M2 segregating material indicated that γ-ray treatment was effective in induction of male sterility. Frequency of visible mutations were higher in sibbed progeny as compared to open pollinated population and male sterile plants were observed only in sibbed population (1000 Gy). Male sterile plants could easily be identified at the flowering stage by their altered floral morphology (disc florets transformed into ligulate ray florets) and complete absence or presence of a rudimentary anther column. Seeds were collected following sib-mating with the fertile counterparts. Progeny segregated in a ration of 3 normal : 1 male sterile. Further work on the mechanism of sterility, maintenance and linkage relationships with associated characters is under progress. This is the first report of induction of male sterility in niger through the use of physical mutagens. The availability of this mutant will be of great value for exploitation of heterosis on commercial basis. (author)

    Full Text Available Introduction: Despite a recent focus on intimate partner violence (IPV among men who have sex with men (MSM, the male-male couple is largely absent from the IPV literature. Specifically, research on dyadic factors shaping IPV in male-male couples is lacking.Methods: We took a subsample of 403 gay/bisexual men with main partners from a 2011 survey of approximately 1,000 gay and bisexual men from Atlanta. Logistic regression models of recent (,12 month experience and perpetration of physical and sexual IPV examined dyadic factors, including racial differences, age differences, and social network characteristics of couples as key covariates shaping the reporting of IPV.Results: Findings indicate that men were more likely to report perpetration of physical violence if they were a different race to their main partner, whereas main partner age was associated with decreased reporting of physical violence. Having social networks that contained more gay friends was associated with significant reductions in the reporting of IPV, whereas having social networks comprised of sex partners or closeted gay friends was associated with increased reporting of IPV victimization and perpetration.Conclusion: The results point to several unique factors shaping the reporting of IPV within male-male couples and highlight the need for intervention efforts and prevention programs that focus on male couples, a group largely absent from both research and prevention efforts.

    Meiotic recombination is believed to produce greater genetic variation despite the fact that deoxyribonucleic acid (DNA)-replication errors are a major source of mutations. In some vertebrates, mutation rates are higher in males than in females, which developed the theory of male-driven evolution (male-biased mutation). However, there is little molecular evidence regarding the relationships between meiotic recombination and male-biased mutation. Here we tested the theory using the frog Rana rugosa, which has both XX/XY- and ZZ/ZW-type sex-determining systems within the species. The male-to-female mutation-rate ratio (α) was calculated from homologous sequences on the X/Y or Z/W sex chromosomes, which supported male-driven evolution. Surprisingly, each α value was notably higher in the XX/XY-type group than in the ZZ/ZW-type group, although α should have similar values within a species. Interestingly, meiotic recombination between homologous chromosomes did not occur except at terminal regions in males of this species. Then, by subdividing α into two new factors, a replication-based male-to-female mutation-rate ratio (β) and a meiotic recombination-based XX-to-XY/ZZ-to-ZW mutation-rate ratio (γ), we constructed a formula describing the relationship among a nucleotide-substitution rate and the two factors, β and γ. Intriguingly, the β- and γ-values were larger and smaller than 1, respectively, indicating that meiotic recombination might reduce male-biased mutations. PMID:26791621

  5. Will male advertisement be a reliable indicator of paternal care, if offspring survival depends on male care?

    Science.gov (United States)

    Kelly, Natasha B.; Alonzo, Suzanne H.

    2009-01-01

    Existing theory predicts that male signalling can be an unreliable indicator of paternal care, but assumes that males with high levels of mating success can have high current reproductive success, without providing any parental care. As a result, this theory does not hold for the many species where offspring survival depends on male parental care. We modelled male allocation of resources between advertisement and care for species with male care where males vary in quality, and the effect of care and advertisement on male fitness is multiplicative rather than additive. Our model predicts that males will allocate proportionally more of their resources to whichever trait (advertisement or paternal care) is more fitness limiting. In contrast to previous theory, we find that male advertisement is always a reliable indicator of paternal care and male phenotypic quality (e.g. males with higher levels of advertisement never allocate less to care than males with lower levels of advertisement). Our model shows that the predicted pattern of male allocation and the reliability of male signalling depend very strongly on whether paternal care is assumed to be necessary for offspring survival and how male care affects offspring survival and male fitness.

    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....... 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......, increasing indirect evidence exists that exposure to ubiquitous endocrine disrupting chemicals, present at measurable concentrations in individuals, might affect development of human fetal testis.

    2013-01-01

    Many drugs have been reported to impair semen parameters, leading to temporary or persistent infertility. Therefore, potential fathers may be concerned about the effect of medications on fertility. We searched the MEDLINE database of articles in English combining key terms including "male infertility," "spermatogenesis," "fertility," "drug effects," and "dermatology." Administration of methotrexate and finasteride has resulted in severe oligospermia and reversible infertility. Ketoconazole has had negative effects on sperm motility and testosterone production. Few individual case reports and a limited number of studies have demonstrated negative effects of tetracyclines, erythromycin, chloroquine, glucocorticoids, spironolactone, and antihistamines on fertility. It is important to counsel male patients when appropriate about the reversible negative effect on fertility when taking methotrexate and finasteride, and the adverse effect of ketoconazole. Patients may be reassured that taking oral retinoids, cyclosporine, azathioprine, and tumor necrosis factor alpha inhibitors should not affect their fertility. PMID:23914891

  9. Periductal mastitis in a male breast

    International Nuclear Information System (INIS)

    Periductal mastitis and mammary duct ectasia are now considered as separate disease entities in the female breast, and these two disease affect different age groups and have different etiologies and clinical symptoms. These two entities have very rarely been reported in the male breast and they have long been considered as the same disease as that in the female breast without any differentiation. We report here on the radiologic findings of a rare case of periductal mastitis that developed during the course of chemotherapy for lung cancer in a 50-year-old male. On ultrasonography, there was a partially defined mass with adjacent duct dilatation and intraductal hypoechogenicity, and this correlated with an immature abscess with a pus-filled, dilated duct and periductal inflammation on the pathologic examination

  12. Darcin: a male pheromone that stimulates female memory and sexual attraction to an individual male's odour

    2010-06-01

    Full Text Available Abstract Background Among invertebrates, specific pheromones elicit inherent (fixed behavioural responses to coordinate social behaviours such as sexual recognition and attraction. By contrast, the much more complex social odours of mammals provide a broad range of information about the individual owner and stimulate individual-specific responses that are modulated by learning. How do mammals use such odours to coordinate important social interactions such as sexual attraction while allowing for individual-specific choice? We hypothesized that male mouse urine contains a specific pheromonal component that invokes inherent sexual attraction to the scent and which also stimulates female memory and conditions sexual attraction to the airborne odours of an individual scent owner associated with this pheromone. Results Using wild-stock house mice to ensure natural responses that generalize across individual genomes, we identify a single atypical male-specific major urinary protein (MUP of mass 18893Da that invokes a female's inherent sexual attraction to male compared to female urinary scent. Attraction to this protein pheromone, which we named darcin, was as strong as the attraction to intact male urine. Importantly, contact with darcin also stimulated a strong learned attraction to the associated airborne urinary odour of an individual male, such that, subsequently, females were attracted to the airborne scent of that specific individual but not to that of other males. Conclusions This involatile protein is a mammalian male sex pheromone that stimulates a flexible response to individual-specific odours through associative learning and memory, allowing female sexual attraction to be inherent but selective towards particular males. This 'darcin effect' offers a new system to investigate the neural basis of individual-specific memories in the brain and give new insights into the regulation of behaviour in complex social mammals.

    2012-01-01

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

    To increase fertilization success, males transfer accessory gland products (Acps). Several species have evolved unconventional Acps transfer modes, meaning that Acps are transferred separately from the sperm. By surveying the sperm-free Acps transfer cases, we show that these animals have evolved a common strategy to deliver Acps: they all inject Acps directly through the partner’s body wall into the hemolymph. Our review of this mode of Acps transfer reveals another striking similarity: they...

    2006-12-01

    If there is a cost to producing a dark color patch, the size of a patch may not correspond with its pigment concentration. The plumage of male house sparrows represents a case of dark, melanin-based ornamentation, but also a case of neglecting the composite nature of dark signals in birds. Here, I investigated what kind of associations exist between the brightness, chroma, and hue of dark integumentary patches and the size of a secondary sexual trait, the bib, in male house sparrows. I found that males with a larger bib also had a darker bib and bill, and a more saturated bib, bill, epaulets, head crown, and breast than small-bibbed males. Male bib coloration in terms of brightness and chroma was more strongly related to bib size than the coloration of other integumentary patches. However, with respect to hue, only the hue of the bill and cheeks was related to bib size. My results indicate that size, brightness, and chroma of the bib, but also chroma of other deeply colored patches, convey redundant information about the signaler's quality in male house sparrows.

  19. The male role in cervical cancer

    2003-01-01

    Full Text Available Experimental, clinical, and epidemiological evidence strongly suggests that genital Human Papillomaviruses (HPVs are predominantly sexually transmitted. Epidemiological studies in virginal and HPV-negative women clearly indicate that sexual intercourse is virtually a necessary step for acquiring HPV. As with any other sexually transmitted disease (STD men are implicated in the epidemiological chain of the infection. Penile HPVs are predominantly acquired through sexual contacts. Sexual contacts with women who are prostitutes play an important role in HPV transmission and in some populations sex workers may become an important reservoir of high-risk HPVs. Acting both as "carriers" and "vectors" of oncogenic HPVs male partners may markedly contribute to the risk of developing cervical cancer in their female partners. Thus, in the absence of screening programs, a woman's risk of cervical cancer may depend less on her own sexual behavior than on that of her husband or other male partners. Although more rarely than women, men may also become the "victims" of their own HPV infections as a fraction of infected men are at an increased risk of developing penile and anal cancers. Male circumcision status has been shown to reduce the risk not only of acquiring and transmitting genital HPVs but also of cervical cancer in their female partners. More research is needed to better understand the natural history and epidemiology of HPV infections in men.

    Full Text Available Androgenetic alopecia (AGA is one of the most common causes of hair loss in genetically predisposed men and women. We studied the therapeutic efficacy and safety of oral finasteride in male patients with AGA. A total of 40 male AGA patients, 18-35 years of age, wad enrolled in the study for a period of 9 months. Oral finasteride, 1mg/day, was started and the drug efficacy was assessed on the basis of pre- and post-treatment clinical photographs, trichogram, hair pull test and self assessment of hair re-growth by the investigators. Routine hematological and bio-chemical investigations and a questionnaire related to sexual disturbances were carried out to assess the safety profile of the drug at each follow-up visit every three months. Improvement in hair growth was observed by comparing the paired pre- and post-treatment global photographs (p<0.05, decreased hair shedding by the patients’ self assessment (p<0.05, hair pull test evaluation (p<0.001 and increase in anagen-telogen hair ratio (p<0.001 with the trichogram, as early as 3 months of finasteride therapy with maximum benefit in the mid-area followed by vertex and frontal areas. No significant side effect related to the drug was observed. It is concluded that oral finasteride is a relatively safe, well tolerated and efficacious drug for AGA in Males.

The aims of this study were twofold: to describe game performance of elite male goalball players based upon the degree of visual impairment, and to determine if game performance was related to anthropometric characteristics of elite male goalball players. The study sample consisted of 44 male goalball athletes. A total of 38 games were recorded during the Summer Paralympic Games in London 2012. Observations were reported using the Game Efficiency Sheet for Goalball. Additional anthropometric measurements included body mass (kg, body height (cm, the arm span (cm and length of the body in the defensive position (cm. The results differentiating both groups showed that the players with total blindness obtained higher means than the players with visual impairment for game indicators such as the sum of defense (p = 0.03 and the sum of good defense (p = 0.04. The players with visual impairment obtained higher results than those with total blindness for attack efficiency (p = 0.04, the sum of penalty defenses (p = 0.01, and fouls (p = 0.01. The study showed that athletes with blindness demonstrated higher game performance in defence. However, athletes with visual impairment presented higher efficiency in offensive actions. The analyses confirmed that body mass, body height, the arm span and length of the body in the defensive position did not differentiate players’ performance at the elite level.

    2009-12-01

    The rise in life expectancy over the last century, together with higher maternal and paternal ages and have highlighted the issue of reduced fertility with advancing age. Aging of the male reproductive system is incited by multi-factorial changes at molecular, cellular and regulatory levels, and individual characteristics are highly variable, although strongly influenced by lifestyle and environmental factors. Damage accumulated with age leads to progressive deregulation of the hypothalamic-pituitary-gonadal axis and of local auto/paracrine interactions, thereby inducing changes in target organs such as the testis, penis and prostate. Elderly human males produce less testosterone, have fewer motile sperm and a higher incidence of erectile dysfunction and prostate disorders, all of which contribute to lower fertility. Cellular aging can manifest itself at several levels. Aging cells progressively accumulate "waste" products, resulting in a decreased functionally. Changes to mitochondria are among the most remarkable features observed in aging cells and several theories place mitochondria at the hub of cellular events related to aging, namely in terms of the accumulation of oxidative damage to cells and tissues, a process in which these organelles may play a prominent role, although alternative theories have also emerged. Furthermore, mitochondrial energy metabolism is also crucial for male reproductive function and mitochondria may therefore constitute a common link between aging and fertility loss. PMID:20021411

  4. From pollen actin to crop male sterility

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    Actin plays an important role in the life activity of animal and plant cells. Pollen cells have plenty of actin whose structure and characteristics are very similar to the animal actin. The nucleotide sequence and amino acid sequence of plant actin gene are very similar to those of the animal gene. The content of pollen actin from male sterile plants is much more lower than that from its maintainer plants. The expression of actin gene is organ-specific during the plant development. The expression quantity of actin gene in pollen is much more higher than those from root, stem and leaf. The expression plasmid of the anti-sense actin gene was constructed, transferred to the protoplasts of wheat and tomato to inhibit the expression of actin gene in pollen and thus the male sterile plants of wheat and tomato were obtained. The actin in pollens from the transgenic plants was reduced significantly, whereas the pistil was not affected. This study might pave a new way to breeding male sterile lines for the application of hybrid vigor of wheat and tomato.

    Aim: To evaluate the role of polychlorinated biphenyls (PCBs) as a potential environmental hazard in the deterioration of male fertility. Methods: Fifty-three males were studied. After a thorough case history evaluation and relevant clinical and laboratory investigations, PCBs were estimated in the seminal plasma of 21 infertile men with “Unexplained Male Factor” and 32 fertile controls. Peak retention times of the eluants were compared with those of the commercially available standard PCB Mix, and the results confirmed spectrophotometrically. Seminal PCB concentrations were compared between i) fertile and infertile men and ii) men from different areas and diets. The relationship between PCB concentrations and measures of sperm quality such as the total motile sperm count, was assessed. Results: PCBs were detected in seminal plasma of infertile men but absent from controls. Sperm quantity and quality were significantly lower in infertile men compared to controls. The highest average PCB concentrations were found in fish-eating urban dwellers, and followed in succession by fish-eating rural dwellers, non fish-eating urban dwellers and non fish-eating rural dwellers. The total motile sperm counts were inversely proportional to the PCB concentrations and were significantly lower than those of the respective controls. Conclusion: PCBs may be instntmental in the deterioration of sperm quantity and quality, a contaminated fish diet being the main source of exposure.(Asian J Androl 2000 Dec;2:263-269)

  6. Eating disorders in the male athlete.

    2006-01-01

    Eating disorders do occur in male athletes. They are less prominent than in female athletes, and therefore in danger of being missed. The high-risk sports fall into the same categories as with females: aesthetic sports, sports in which low body fat is advantageous, such as cross-country and marathon running, and sports in which there is a need to "make weight", including wrestling and horse racing. Athletic involvement may foster the development of an eating disorder. Some male athletes, in their preoccupation with body image, will abuse anabolic steroids. While sports participation may contribute to the aetiology of an eating disorder, the converse is also true. Exercise may be used as therapy for some cases of eating disorder. In order to adequately treat eating disorders in the male athlete, it is first essential to identify cases. Psychoeducation of athletes, their families, coaches and trainers is an important first step. Counselling an athlete to pursue a sport appropriate to his body type, or to leave his sport behind altogether (an unpopular recommendation from a coach's perspective) can be important to treatment. Treatment of co-morbid psychiatric conditions is essential. Treatment can be structured using a biopsychosocial approach, and all appropriate modalities of therapy, including individual, family and group, as well as psychopharmacotherapy, where appropriate, should be applied.

    The present study reviews the use of assisted reproductive technology in male cancer survivors and their partners. As antineoplastic treatment with chemotherapy or radiation therapy, has the potential of inducing impairment of spermatogenesis through damage of the germinal epithelium, many male cancer survivors experience difficulties in impregnating their partners after treatment. The impairment can be temporary or permanent. While many cancer survivors regain spermatogenesis months to years after treatment, some become infertile with a-, oligo- or azoospermia. An option to secure the fertility potential of young cancer patients is to cryopreserve semen before cancer treatment for later use. A desired pregnancy may be obtained in couples where the husband has a history of cancer, using assisted reproductive technology with either fresh or cryopreserved/thawed semen. Successful outcomes have been obtained with intrauterine insemination (IUI) as well as in vitro fertilization (IVF) with or without the use of intracytoplasmic sperm injection (ICSI). In conclusion, male cancer survivors and their partners who have failed to obtain a pregnancy naturally within a reasonable time frame after end of treatment should be referred to a fertility clinic.

  8. Competition for trophies triggers male generosity.

    Directory of Open Access Journals (Sweden)

    Xiaofei Sophia Pan

    Full Text Available BACKGROUND: Cooperation is indispensable in human societies, and much progress has been made towards understanding human pro-social decisions. Formal incentives, such as punishment, are suggested as potential effective approaches despite the fact that punishment can crowd out intrinsic motives for cooperation and detrimentally impact efficiency. At the same time, evolutionary biologists have long recognized that cooperation, especially food sharing, is typically efficiently organized in groups living on wild foods, even absent formal economic incentives. Despite its evident importance, the source of this voluntary compliance remains largely uninformed. Drawing on costly signaling theory, and in light of the widely established competitive nature of males, we hypothesize that unique and displayable rewards (trophies out of competition may trigger male generosity in competitive social environments. PRINCIPAL FINDINGS: Here, we use a controlled laboratory experiment to show that cooperation is sustained in a generosity competition with trophy rewards, but breaks down in the same environment with equally valuable but non-unique and non-displayable rewards. Further, we find that males' competition for trophies is the driving force behind treatment differences. In contrast, it appears that female competitiveness is not modulated by trophy rewards. SIGNIFICANCE: Our results suggest new approaches to promoting cooperation in human groups that, unlike punishment mechanisms, do not sacrifice efficiency. This could have important implications in any domain where voluntary compliance matters--including relations between spouses, employers and employees, market transactions, and conformity to legal standards.

    Because cancer of the male breast is rare knowledge about its biology and behavior is essentially due to a compilation of pooled experiences. Hence, a continued report of cases appears to be important. Therefore a retrospective review of patients suffering from male breast cancer was carried out. Twenty-four evaluable cases were analyzed. Eight patients (1 patient with bilateral Stage I carcinoma was included) were in Stage I, 7 in Stage II, 2 in Stage IIIa, 4 in Stage IIIb, and 3 in Stage IV. Of 23 patients who were treated with mastectomy, 22 had modified radical mastectomy and postoperative irradiation to the chest wall as well as to the peripheral lymphatic areas in most cases. One patient underwent radical mastectomy. Another patient had an excision biopsy only, followed by irradiation. One of 24 patients received tamoxifen; another received cyclophosphamide, methotrexate, 5-fluorouracil, prednisone (CMF) regimen in an adjuvant setting. Local recurrence developed in one of 23 (4%) patients treated with mastectomy and radiation therapy to the chest wall and peripheral lymphatics. Four (17%) patients developed distant metastases. The 5-year overall survival (Kaplan-Maier) was 90% for the entire group, 100% for patients in Stage I-III disease, and 60% in Stage IV disease (P = < 0.005). As observed in former reports the stage of disease at initial presentation seems to be a parameter that significantly contributes to survival in male breast cancer patients. To what extent improved local control by adequate local therapy, such as surgery and postoperative radiotherapy, may improve overall survival remains to be discussed. (orig.)

    Male sexual responses are reflexes mediated by the spinal cord and modulated by neural circuitries involving both the peripheral and central nervous system. While the brain interact with the reflexes to allow perception of sexual sensations and to exert excitatory or inhibitory influences, penile reflexes can occur despite complete transections of the spinal cord, as demonstrated by the reviewed animal studies on spinalization and human studies on spinal cord injury. Neurophysiological and neuropharmacological substrates of the male sexual responses will be discussed in this review, starting with the spinal mediation of erection and its underlying mechanism with nitric oxide (NO), followed by the description of the ejaculation process, its neural mediation and its coordination by the spinal generator of ejaculation (SGE), followed by the occurrence of climax as a multisegmental sympathetic reflex discharge. Brain modulation of these reflexes will be discussed through neurophysiological evidence involving structures such as the medial preoptic area of hypothalamus (MPOA), the paraventricular nucleus (PVN), the periaqueductal gray (PAG), and the nucleus para-gigantocellularis (nPGI), and through neuropharmacological evidence involving neurotransmitters such as serotonin (5-HT), dopamine and oxytocin. The pharmacological developments based on these mechanisms to treat male sexual dysfunctions will complete this review, including phosphodiesterase (PDE-5) inhibitors and intracavernous injections (ICI) for the treatment of erectile dysfunctions (ED), selective serotonin reuptake inhibitor (SSRI) for the treatment of premature ejaculation, and cholinesterase inhibitors as well as alpha adrenergic drugs for the treatment of anejaculation and retrograde ejaculation. Evidence from spinal cord injured studies will be highlighted upon each step. PMID:23360268

    To gain better understanding into the causes of molesting behaviour in males, we examined a prison cohort of molesters and compared them with a control group comprising thieves. The molesters were older, had attained a higher educational level and were more likely to be married. They had their initial sexual intercourse at an older age but tended to have multiple sexual relationships and were less likely to report having viewed pornographic material. Three months prior to committing their offences, molesters seemed to engage in less sexual activity. The implications are that molesters had a need for more explicit sexual contact but were unable to sustain ongoing, stable, intimate sexual relationships. PMID:11281351

Methods:This study examined 390 male school children aged 10-19 years in the rural and urban areas of district Aligarh, Uttar Pradesh, India. Data was analyzed by SPSS -10. Findings:Substance abuse was prevalent in 13.3% of adolescents of whom 96.1% were using various forms of tobacco and 3.8% were taking alcohol. While there was statistically significant association between the substance abuse and the age group of adolescents and size of their families, variables such as religion, socioeconomic status, place of residence were not associated with substance use. Most of the students reported initiation of substance use at 14 yrs of age due to peer pressure. Conclusion:Peer educators would be a useful strategy for communication with adolescents to counter peer pressure. The prevention and control measures should be started at primary education level.

    2016-07-01

    World population continues to grow at an unprecedented rate, doubling in a mere 50years to surpass the 7-billion milestone in 2011. This steep population growth exerts enormous pressure on the global environment. Despite the availability of numerous contraceptive choices for women, approximately half of all pregnancies are unintended and at least half of those are unwanted. Such statistics suggest that there is still a gap in contraceptive options for couples, particularly effective reversible contraceptives for men, who have few contraceptive choices. Male hormonal contraception has been an active area of research for almost 50years. The fundamental concept involves the use of exogenous hormones to suppress endogenous production of gonadotropins, testosterone, and downstream spermatogenesis. Testosterone-alone regimens are effective in many men but high dosing requirements and sub-optimal gonadotropin suppression in 10-30% of men limit their use. A number of novel combinations of testosterone and progestins have been shown to be more efficacious but still require further refinement in delivery systems and a clearer understanding of the potential short- and long-term side effects. Recently, synthetic androgens with both androgenic and progestogenic activity have been developed. These agents have the potential to be single-agent male hormonal contraceptives. Early studies of these compounds are encouraging and there is reason for optimism that these may provide safe, reversible, and reliable contraception for men in the near future. PMID:27016468

    Contraception is important from a health, psychological and socioeconomic point of view. Due to the fact that male-based contraceptive methods are mostly represented by condoms and vasectomy, researchers are working on the new solutions, which could let the men be more involved in a conscious family planning. In this review we will present the current state of knowledge on this subject. There is a lot going on in the field of hormonal contraception. Studies including testosterone, progestins, synthetic androgens and other derivatives are on a different stages of clinical trials and mostly demonstrate high efficacy rates. Recent discovers of Izumo and Juno proteins, essential for the fertilization process, give hope for an easily reversible, non-hormonal method. Researchers are also trying to interfere with the process of spermatogenesis using BRDT inhibitor - JQ1, or neutralize the sperm by injecting styrene maleic anhydride (SMA) into the lumen of the vas deferens. The other studies explore processes involved in proper sperm motility. A vaccine which induces an immune response to the reproductive system is also an interesting method. The latest research use ultrasound waves and mechanical device which blocks the patency of vas deferens. The aim of the study current state of knowledge male contraception. PMID:27591451

    To expand our present understanding of the effects of chromium on male fertility a number of studies were designed to achieve this through the use of chromium intoxicated experimental animals and through investigation of sexual hormones and sperm quality in welders. Also in view of the lack of an experimental model for effects of noxious substance on the epididymal spermatozoa the main objectives of the series of studies reviewed here were: A. To establish a model for evaluation of epididymal sperm count and motility in the rat. B. To investigate and compare the effects of tri- and hexavalent chromium on epididymal spermatozoa. Further to describe the effects of low-dose long-time exposure of rats to the most toxicological interesting chromium oxidative state - hexavalent chromium. C. By the use of autoradiography and γ-countinuing to expand the present knowledge on the distribution of chromium in the body with special reference to the male reproductive organs. D.

    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

  14. Male infertility: an obstacle to sexuality?

    2016-05-01

    Interactions between infertility and sexuality are numerous and complex. Infertile men may suffer from sexual dysfunction (SD) when undergoing an assisted reproductive technology programme. We undertook a review both in French and English of the available data on male SD when being diagnosed with a fertility problem with a specific focus on azoospermic men. The review was performed over a 30-year time period using PubMed/Medline. The sexual concerns and needs of infertile/sterile men for whom potential parenting can be compromised were evaluated. When diagnosed with infertility, men usually go through a crisis that can have a deleterious effect on their sexuality with sometimes a feeling of sexual inadequacy. Infertile men will feel stigmatized because they are perceived as being deficient in a specific component of their masculinity. Hence, subsequent SD may occur that can impact the couple sexuality and the infertility management. However, little is known on how the announcement of azoospermia may affect male on a sexual and psychological point of view. The present review suggests that a global management through a healthcare network (biologist, andrologist, sexologist and psychologist) is required which will allow to consider infertility and its subsequent sexual disorders as a whole and not as dichotomized issues.

    2002-05-01

    Researchers have suggested that human voices are represented in memory in terms of prototypes [e.g., Kreiman and Papcun (1991); Papcun et al. (1989)]. Others have suggested that speech utterances are stored in memory via detailed exemplar-based representations [e.g., Lachs et al. (2000)]. The goal of the present study was to provide the first step toward assessing the viability of a prototype view of voice. Ten hVd utterances were recorded from each of 20 male and 20 female speakers. The utterances were blocked by speaker gender and presented to male and female listeners who rated each stimulus on a 1-7 typicality scale from ``least typical voice'' to ``most typical voice.'' There were significant effects of the type of vowel and speaker voice on the ratings, as well as interactions of vowel type with gender of subject and speaker voice. The results are discussed in terms of the strength of evidence for a graded category structure of voice categories that would be consistent with a prototype perspective of long-term memory representations of voice.

    2014-01-01

    Using in-depth interviews with 74 men across different ranks in biology and physics at prestigious US universities, we ask to what extent changing norms of fatherhood and a flexible workplace affect men working in a highly male-dominated profession and what variation exists in family forms. We conceptualize four typologies of men: those forgoing children, egalitarian partners, neo-traditional dual-earners, and traditional breadwinners. Findings suggest male scientists hold strong work devotions yet a growing number seek egalitarian relationships, which they frame as reducing their devotion to work. The majority of men find the all-consuming nature of academic science conflicts with changing fatherhood norms. PMID:25419040

    Analyses of spatial relationships and social interactions provide insights into the social structure of animal societies and the ways in which social preferences among and between dyads affect higher order social relationships.In this paper we describe the patterns of spatial associations and social interactions among adult male northern muriquis in order to evaluate the dynamics of their social networks above the dyadic levels.Systematic observations were made on the 17 adult males present in a multi-male/multi-female group from April 2004 through February 2005,and in July 2005.Analyses of their spatial relationships identified two distinct male cliques; some adult males (called "N" males) were more connected to the females and immatures than other adult males ("MU" males),which were more connected to one another.Affiliative interactions were significantly higher among dyads belonging to the same clique than to different cliques.Although frequencies of dyadic agonistic interactions were similarly low among individuals within and between cliques,MU males appeared to be subordinate to N males.Nonetheless,there were no significant differences in the copulation rates estimated for MU males and N males.Mutual benefits of cooperation between MU and N cliques in intergroup encounters might explain their ongoing associations in the same mixed-sex group [Current Zoology 58 (2):342-352,2012].

    We propose a new mechanism for diversification of male nuptial-colour patterns in the rapidly speciating cichlid fishes of Lake Victoria. Sympatric closely related species often display nuptial colours at opposite ends of the spectrum with males either blue or yellow to red. Colour polymorphisms within single populations are common too. We propose that competition between males for breeding sites promotes such colour diversification, and thereby speciation. We hypothesize that male aggression...

  8. Male-male sexual behavior in Japanese quail: being "on top" reduces mating and fertilization with females.

    Science.gov (United States)

    Adkins-Regan, Elizabeth

    2014-10-01

    Male Japanese quail (Coturnix japonica) engage in vigorous same-sex sexual interactions that have been interpreted as aggressive behavior reflecting dominance relationships. The consequences of this behavior for reproductive success, and whether it is a form of competition over mating and fertilization, are unclear. Three experiments were conducted to determine the effect of seeing or interacting with another male on a male's subsequent mating and fertilization success with females. A vigorous interaction with another male in which the subject performed more cloacal contact movements (movements to try to make contact with the other bird's cloacal opening) reduced subsequent mating and fertilization success with a female to a similar extent as a prior mating with a different female. Receiving one or more cloacal contacts from another male was less detrimental for subsequent success. The mere presence of another (stimulus) male delayed mating initiation in those male subjects that approached the stimulus first instead of the female. These results do not support the idea that the male "on top" in male-male sexual interactions is the dominant bird who goes on to achieve greater reproductive success. Instead, the results are consistent with male-male sexual behavior as an occasionally costly by-product of strong mating motivation. PMID:25264235

  12. Male-to-male transmission in extended pedigrees with multiple cases of autism

    1996-02-16

    Despite strong genetic influences in autism, the true mode of inheritance remains unknown. Sex differences in autism have been described in both singleton and multiplex families: boys outnumber girls by 3 or 4 to 1, and so a sex-linked mode of transmission must also be considered. The key characteristic of X-linkage is that all sons of affected men are unaffected (no male-to-male transmission). In the present study, which is part of an ongoing linkage project in autism, we describe 77 multiplex autism families, 11 of who are affected cousin or half-sibling families. By using these families, it is possible to trace the path of genetic transmission and observe whether the hypothesis of X-linkage is tenable. Of 11 extended pedigrees from 77 multiplex families, six show male-to-male transmission; in these families, X-linkage can be excluded as the genetic basis for their autism. The data from the other five families are compatible with either an autosomal or an X-linked mode of transmission. The key point to emerge, then, is that autism cannot be exclusively an X-linked disorder; there must be an autosomal mode of transmission at least in some families. Thus we must consider the alternative hypotheses that autism is either entirely autosomal, or it is genetically heterogeneous, involving at least one autosomal locus with gender-specific expression, as well as a possible locus on the X-chromosome. 28 refs., 1 fig.

  14. Variation in male mate choice in Drosophila melanogaster.

    Directory of Open Access Journals (Sweden)

    Dominic A Edward

    Full Text Available Male mate choice has been reported in the fruit fly, Drosophila melanogaster, even though males of this species were previously thought to maximise their fitness by mating with all available females. To understand the evolution of male mate choice it is important to understand variation in male mating preferences. Two studies, using different stock populations and different methods, have reported contrasting patterns of variation in male mate choice in D. melanogaster. Two possible explanations are that there are evolved differences in each stock population or that the methods used to measure choice could have biased the results. We investigated these hypotheses here by repeating the methods used in one study in which variable male mate choice was found, using the stock population from the other study in which choice was not variable. The results showed a significant resource-independent male preference for less fecund, smaller females, which contrasts with previous observations of male mate choice. This indicates that different selection pressures between populations have resulted in evolved differences in the expression of male mate choice. It also reveals phenotypic plasticity in male mate choice in response to cues encountered in each choice environment. The results highlight the importance of variation in male mate choice, and of identifying mechanisms in order to understand the evolution of mate choice under varying ecological conditions.

  15. Evolution of male-killer suppression in a natural population.

    Emily A Hornett

    2006-09-01

    Full Text Available Male-killing bacteria are widespread in arthropods, and can profoundly alter the reproductive biology of their host species. Here we detail the first case of complete suppression of a male killer. The nymphalid butterfly Hypolimnas bolina is infected with a strain of the bacterium Wolbachia, wBol1, which kills male host embryos in Polynesian populations, but does not do so in many areas of Southeast Asia, where both males and female adults are naturally infected, and wBol1-infected females produce a 1:1 sex ratio. We demonstrate that absence of male killing by wBol1 is associated with dominant zygotic suppression of the action of the male killer. Simulations demonstrate host suppressors of male-killer action can spread very rapidly, and historical data indicating the presence of male killing in Southeast Asia in the very recent past suggests suppressor spread has been a very recent occurrence. Thus, male killer/host interactions are much more dynamic than previously recognised, with rapid and dramatic loss of the phenotype. Our results also indicate that suppression can render male killers completely quiescent, leading to the conclusion that some species that do not currently express a male killer may have done so in the past, and thus that more species have had their biology affected by these parasites than previously believed.

    2013-06-01

    Although researchers have examined the negative effects of viewing reality television (RTV) on women's body image, this research has not been extended to men. Exploring the extent to which RTV depicts men who embody the muscular ideal may enhance our understanding of the potential influence of this media genre. We explored the extent to which RTV depicted men who embodied the muscular ideal using a quantitative content analysis. Based on binomial tests, the primary male cast members of programs airing on networks popular among young adult men during the Fall 2009 broadcast season were more muscular, with lower levels of body fat, than average U.S. men. The chest-to-waist and shoulder-to-waist ratios of these cast members did not differ as a function of program type (i.e., reality drama, endurance, and romance). Young men who view RTV programs included in the present study would be exposed to an unrepresentative muscular ideal. PMID:23523084

    Environmental contaminants such as persistent organic pollutants (POPs) are man-made bioaccumulative compounds with long half-lives that are found throughout the world as a result of heavy use in a variety of consumer products during the twentieth century. Wildlife and animal studies have long...... suggested adverse effects of exposure to these compounds on human reproductive health, which, according to the endocrine disrupter hypothesis, are ascribed to the compounds' potential to interfere with endocrine signaling, especially when exposure occurs during certain phases of fetal and childhood...... development. An extensive number of epidemiological studies have addressed the possible effects of exposure to POPs on male reproductive health, but the results are conflicting. Thus far, most studies have focused on investigating exposure and the different reproductive health outcomes during adulthood. Some...

    2010-01-01

    Full Text Available Ghrelin and one of its functional receptors, GHS-R1a (Growth Hormone Secretagogue Receptor 1a, were firstly studied about 15 years. Ghrelin is a multifunctional peptide hormone that affects several biological functions including food intake, glucose release, cell proliferation… Ghrelin and GHS-R1a are expressed in key cells of both male and female reproductive organs in several species including fishes, birds, and mammals suggesting a well-conserved signal through the evolution and a role in the control of fertility. Ghrelin could be a component of the complex series of nutrient sensors such as adipokines, and nuclear receptors, which regulate reproduction in function of the energy stores. The objective of this paper was to report the available information about the ghrelin system and its role at the level of the hypothalamic-pituitary-gonadal axis in both sexes.

    2014-03-01

    Prevalence, pathophysiology, diagnostic and therapeutic approaches of urinary incontinence are well studied in women; however, studies on male urinary incontinence focus on incontinence following surgery of the bladder or prostate, predominantly incontinence after radical prostatectomy. Aging men suffer from incontinence, most frequently urge incontinence (overactive bladder, OAB), nearly as often as women do.The domain of conservative therapy of urinary stress incontinence in men is pelvic floor training. It remains unclear whether biofeedback procedures, electrostimulation therapy, or magnetic stimulation therapy can enhance pelvic floor training. There are data suggesting that an off-label therapy with Duloxetin®, a selective serotonin-noradrenaline reuptake inhibitor (SSNRI), improves urinary incontinence following radical prostatectomy. Antimuscarinic agents in combination with bladder training have been proven as safe and effective treatment in men with OAB. Data, however, suggest that men with OAB are far less frequently treated than women. PMID:24585116

    Conflicting evidence exists regarding whether bisexual-identified men are sexually aroused to both men and women. We hypothesized that a distinct characteristic, level of curiosity about sexually diverse acts, distinguishes bisexual-identified men with and without bisexual arousal. Study 1 assessed men's (n=277) sexual arousal via pupil dilation to male and female sexual stimuli. Bisexual men were, on average, higher in their sexual curiosity than other men. Despite this general difference, only bisexual-identified men with elevated sexual curiosity showed bisexual arousal. Those lower in curiosity had responses resembling those of homosexual men. Study 2 assessed men's (n=72) sexual arousal via genital responses and replicated findings of Study 1. Study 3 provided information on the validity on our measure of sexual curiosity by relating it to general curiosity and sexual sensation seeking (n=83). Based on their sexual arousal and personality, at least two groups of men identify as bisexual. PMID:24055219

    Full Text Available The first operative procedure in sex reassignment surgery (SRS for female-to-male transsexuals (FTMTS is mastectomy. This procedure includes the removal of mammary tissue, removal of excess skin, and reduction and proper repositioning of the nipple and areola complex. We have performed mastectomies in over 120 patients since January 2001 and want to describe the operative procedures we have developed. We classified our patients into 3 groups according to the patient's breast volume and the degree of ptosis, and we selected the operative procedure that was suitable for each group. At present all costs for SRS are assumed by the patient in Japan. If the FTMTS patient undergoes the entire series of SRS operations, he has to pay more than 3,000,000 yen. Thus the surgeon should select the proper operative procedure so that the patient can avoid unnecessary additional operations. We describe herein the techniques and the strategy for performing mastectomy in FTMTS.

    A cross-sectional study was conducted to explore the prevalence and severity of health-related complaints perceived by adult males of Hong Kong by using the Hong Kong Traditional Chinese versions of the Aging males' symptoms (AMS) scale and the 5-dimensional and 3-level European Quality of life (EQ-5D-3L) questionnaire. A total of 825 adult males aged 40 years or above were surveyed, and observed that 80% of the population was living with little-to-mild levels of aging symptoms with mean total scores ranged between 26.02 ± 7.91 and 32.99 ± 7.91 in different age groups. Such symptoms were correlated with age, especially for the somato-vegetative and sexual symptoms. The most severe AMS symptoms were observed in the oldest age group at 70 years or above, with 76%, 34% and 70% living with moderate-to-severe levels of somato-vegetative, psychological and sexual symptoms, respectively. The result was highly correlated with the EQ-5D-3L questionnaire. Secondly, the Hong Kong Aging males' symptoms (AMS) scale was shown to have good reliability with test-retest coefficient at 0.79 (ranged 0.66-0.87) and Cronbach's alpha coefficient at 0.88 (ranged 0.70-0.84). In summary, the population of Hong Kong male adults was commonly living with little-to-mild levels of aging symptoms, whereas their severity was correlated with age. PMID:27068128

    2013-01-01

    This paper analyses the views of 20 Japanese mothers concerning paediatric male circumcision and penile hygiene. In Japan, routine male circumcision has never been implemented for newborns and children, and adult males are mostly circumcised at aesthetic clinics. However, media reports indicate a trend of Japanese mothers willing to have their sons circumcised. In discussing penile hygiene and male circumcision, the construct of a 'sexual script' becomes relevant to understanding how linguistic and gender barriers made references to male genitalia and penile hygiene largely appear as 'vulgar' and 'unfeminine' in daily life conversations. Peers were often identified as the main source of information and only mothers who have struggled with their children's penile infections have learnt about male genital hygiene, a domain of knowledge largely transmitted by men. Male circumcision becomes a double-edged sword that could help prevent penile infections but also an embarrassing conversational topic that could elicit discrimination because most Japanese children are uncircumcised.

    Full Text Available A prospective placebo controlled double blind study was conducted in patients attending male infertility clinics of our hospital to evaluate effects of a herbal formulation for male infertility--′Y-virilin′. In phase 1 forty patients with oligospermia with or without asthenospermia were randomly allocated to 2 treatment groups--Treatment Group A i.e. formulation under test and treatment Group B (Placebo. Therapy with these agents was given twice a day for 6 months. In phase 2, 12 patients with azospermia were administered either ′Y virilin′ or the placebo (n = 6/Gp. In all patients along with semen analysis (sperm count, percentage of motile sperms and grade of motility was done monthly for 6 months. Serum FSH levels were estimated before and at the end of therapy. A significant increase in sperm count was observed from 2-3 months in oligospermics receiving Y virilin as compared to basal values (p < 0.05. In Group B the follow-up sperm counts were either comparable to basal values or were lesser. However, the percentage and grade of motility did not differ in two groups at the end of respective treatment. No change was found in mean FSH value. During the therapy period incidence of conception was 20% in treatment Group A and 5% in Group B. Of the azospermic receiving ′Y-virilin′ 50% showed a count of 10-20 millions/cmm while none from the placebo group. This study highlights the therapeutic potential of the tested formulation in the patients with infertility.

  5. The epididymis, cytoplasmic droplets and male fertility

    2011-01-01

    The potential of spermatozoa to become motile during post-testicular maturation,and the relationship between the cytoplasmic droplet and fertilizing capacity are reviewed.Post-testicular maturation of spermatozoa involves the autonomous induction of motility,which can occur in vivo in testes with occluded excurrent ducts and in vitro in testicular explants,and artefactual changes in morphology that appear to occur in the testis in vitro.Both modifications may reflect time-dependent oxidation of disulphide bonds of head and tail proteins.Regulatory volume decrease(RVD),which counters sperm swelling at ejaculation,is discussed in relation to loss of cytoplasmic droplets and consequences for fertility.It is postulated that:(i)fertile males possess spermatozoa with sufficient osmolytes to drive RVD at ejaculation,permitting the droplet to round up and pinch off without membrane rupture; and(ⅱ)infertile males possess spermatozoa with insufficient osmolytes so that RVD is inadequate,the droplet swells and the resulting flagellar angulation prevents droplet loss.Droplet retention at ejaculation is a harbinger of infertility caused by failure of the spermatozoon to negotiate the uterotubal junction or mucous and reach the egg.In this hypothesis,the epididymis regulates fertility indirectly by the extent of osmolyte provision to spermatozoa,which influences RVD and therefore droplet loss.Man is an exception,because ejaculated human spermatozoa retain their droplets.This may reflect their short midpiece,approximating head length,permitting a swollen droplet to extend along the entire midpiece; this not only obviates droplet migration and flagellar angulation but also hampers droplet loss.

  6. Oxidative stress and male reproductive health

    Directory of Open Access Journals (Sweden)

    Robert J Aitken

    2014-02-01

    Full Text Available One of the major causes of defective sperm function is oxidative stress, which not only disrupts the integrity of sperm DNA but also limits the fertilizing potential of these cells as a result of collateral damage to proteins and lipids in the sperm plasma membrane. The origins of such oxidative stress appear to involve the sperm mitochondria, which have a tendency to generate high levels of superoxide anion as a prelude to entering the intrinsic apoptotic cascade. Unfortunately, these cells have very little capacity to respond to such an attack because they only possess the first enzyme in the base excision repair (BER pathway, 8-oxoguanine glycosylase 1 (OGG1. The latter successfully creates an abasic site, but the spermatozoa cannot process the oxidative lesion further because they lack the downstream proteins (APE1, XRCC1 needed to complete the repair process. It is the responsibility of the oocyte to continue the BER pathway prior to initiation of S-phase of the first mitotic division. If a mistake is made by the oocyte at this stage of development, a mutation will be created that will be represented in every cell in the body. Such mechanisms may explain the increase in childhood cancers and other diseases observed in the offspring of males who have suffered oxidative stress in their germ line as a consequence of age, environmental or lifestyle factors. The high prevalence of oxidative DNA damage in the spermatozoa of male infertility patients may have implications for the health of children conceivedin vitro and serves as a driver for current research into the origins of free radical generation in the germ line.

  7. Erectile Dysfunction in Males on Hemodialysis

    International Nuclear Information System (INIS)

    Objective: The determine the frequency of erectile dysfunction in males on hemodialysis. Study Design: Descriptive study. Place and duration: Hemodialysis unit, Combined Military Hospital Kharian from October 2011 to April 2012. Patients and Methods: A total of 150 married male patients of end stage renal disease (ESRD) on hemodialysis were included in the study. Patients with cognitive and/or communication deficits and on hemodialysis for less than 06 months were excluded from the study. Erectile dysfunction (ED) was assessed using International Index of Erectile Function-5 (IIEF-5). Frequency of erectile dysfunction (ED) was analyzed using Statistical Package for Social Sciences (SPSS) version 17. Results: Mean age of the patients were 52.89 = 8.25 years. Mean duration of hemodialysis was 34 +- 9.62 months. The underlying etiology of end stage renal disease were diabetic nephropathy 69(46%), hypertensive nephropathy 51(34%), obstructive nephropathy 18(12%), glomerulonephritis 9(6%), autosomal polycystic kidney disease 3(2%). Mean IIEF-5 score was 13.29 +- 6.38. The frequency of erectile dysfunction was 74%. The majority of the patients, 73(48.7%) had moderate erectile dysfunction, while 24 (16%) had severe and 14 (9.3%) had mild erectile dysfunction. Out of total 150 patients enrolled, 39 (26%) patients had no erectile dysfunction. Conclusion: ED is a highly prevalent problem in men with ESRD. Physicians are urged to recognize the high prevalence of erection problems in men with ESRD and proactively question all patients regarding their sexual function. This will not only improve the recognition of this condition among these patients but also improve the quality of life after adequate treatment. (author)

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, 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. Also it needed supervision of expert haematologist for adjusting treatment to ensure control of unwanted bleeding.

    Purpose/ Chemoradiotherapy is the standard treatment of inoperable and/or non-resectable IIIA/B non-small-cell lung cancer (N.S.C.L.C.). Aware of the necessity to increase local control in locally advanced N.S.C.L.C., we analyzed the feasibility of high-dose three-dimensional conformal radiation therapy (3D-C.R.T.) in the treatment of localised N.S.C.L.C. Patients and methods: We undertook a retrospective analysis of consecutive patients with non-resectable N.S.C.L.C. treated with high-dose (74 Gy) standard-fractionation 3D-C.R.T., with particular attention to the relationship between lung and heart radiation-induced toxicities. Results: Fifty patients (41 males, 9 females) were included. A total of 35 (70%) patients received the planned total dose of 74 Gy. Patients irradiated to inferior doses interrupted the treatment because of limiting toxicities. Induction and concurrent chemotherapy was delivered to 39 (78%) and 14 (28%) patients, respectively. Eight (16%) patients experienced grade 3-4 acute lung toxicity, all of them having a history of pulmonary disease, a FEV1 below 1.6 L, and a lung V20 of at least 25%. Three (6%) patients were deemed to experience radiation-induced cardiac toxicity. Conclusions: This study assesses the feasibility of delivering a total dose of 74 Gy combined with chemotherapy in locally advanced N.S.C.L.C.. High lung and heart V20 increases the risk of radiation-induced lung and cardiac toxicity, the later being highly difficult to precisely assess, as late deaths are rarely documented, and responsibility of the treatment might be often underestimated. The precise evaluation of cardiac condition may be helpful to spare fragile patients from potentially toxic effects of high-dose radiation, especially in controlled trials. (authors)

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

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

  11. Male Headship as Male Agency: An Alternative Understanding of a ‘Patriarchal’ African Pentecostal Discourse on Masculinity

    Directory of Open Access Journals (Sweden)

    Adriaan S. van Klinken

    2011-09-01

    Full Text Available In some Christian circles in Africa, male headship is a defining notion of masculinity. The central question in this article is how discourses on masculinity that affirm male headship can be understood. A review of recent scholarship on masculinities and religion shows that male headship is often interpreted in terms of male dominance. However, a case study of sermons in a Zambian Pentecostal church shows that discourse on male headship can be far more complex and can even contribute to a transformation of masculinities. The main argument is that a monolithic concept of patriarchy hinders a nuanced analysis of the meaning and function of male headship in local contexts. The suggestion is that in some contexts, male headship can be understood in terms of agency.

    Infertility is a common condition experienced by many men and women, and treatments are expensive. The World Health Organization and American Society of Reproductive Medicine define infertility as a disease, yet private companies infrequently offer insurance coverage for infertility treatments. This is despite the clear role that healthcare insurance plays in ensuring access to care and minimizing the financial burden of expensive services. In this review, we assess the current knowledge of how male infertility care is covered by insurance in the United States. We begin with an appraisal of the costs of male infertility care, then examine the state insurance laws relevant to male infertility, and close with a discussion of why insurance coverage for male infertility is important to both men and women. Importantly, we found that despite infertility being classified as a disease and males contributing to almost half of all infertility cases, coverage for male infertility is often excluded from health insurance laws. Excluding coverage for male infertility places an undue burden on their female partners. In addition, excluding care for male infertility risks missing opportunities to diagnose important health conditions and identify reversible or irreversible causes of male infertility. Policymakers should consider providing equal coverage for male and female infertility care in future health insurance laws. PMID:27030084

  14. Induced mutant for male-sterility of lentil

    International Nuclear Information System (INIS)

    Full text: Lentil has very small flowers which pose problems in emasculation for cross-breeding. To induce mutations, seeds of variety LL-78 were irradiated with gamma rays 5 to 20 krad. In M2 some male-sterile plants were observed. Male-sterile plants could easily be identified at the start of maturity. They remain green and continue flowering when other plants mature. Due to natural outcrossing a few seeds formed on these male-sterile plants. These were grown in M2 for progeny testing. Some M3 lines were having both normal seed set and male-sterile plants in the ratio of 3 normal : 1 male-sterile, whereas in other lines all the plants were male-sterile. The former are assumed to be genic male-sterile and the latter cytoplasmic male-sterile. When the putative cytoplasmic male-sterile plants were selfed, there was no seed setting. Cytoplasmic male-sterility has not yet been reported in lentil. its use could make cross-breeding easier. (author)

    Cooperative behaviors are promoted by kin selection if the costs to the actor are smaller than the fitness benefits to the recipient, weighted by the coefficient of relatedness. In primates, cooperation occurs primarily among female dyads. Due to male dispersal before sexual maturity in many primate species, however, it is unknown whether there are sufficient opportunities for selective tolerance and occasional coalitionary support for kin selection to favor male nepotistic support. We studied the effect of the presence of male kin on correlates of male reproductive success (residence time, duration of high dominance rank) in non-natal male long-tailed macaques (Macaca fascicularis). We found that "related" (i.e., related at the half-sibling level or higher) males in a group have a significantly higher probability to remain in the non-natal group compared to males without relatives. Moreover, males stayed longer in a group when a relative was present at group entry or joined the same group within 3 months upon arrival. Males with co-residing relatives also maintained a high rank for longer than those without. To our knowledge, this is the first demonstration of a potential nepotistic effect on residence and rank maintenance among non-natal males in a social system without long-term alliances.

    Full Text Available BACKGROUND: The issues of the age effect (the theory of the age influence have been shown in sport sciences since the 1980s. The theory of age effect works on the assumption that athletes born in the beginning of a calendar year are, particularly in children’s and junior age, more successful than athletes born in the end of the year. This fact has been proved by a number of research studies, mainly in ice hockey, soccer, and tennis but also in other sports. OBJECTIVE: The submitted contribution is aimed at verifying of the age effect in junior tennis. The research objective was to find out the distribution of birth date frequencies in a population of tennis players’ in individual months, quarters, and half-years in the observed period 2007–2011 and to check the significance of differences. METHODS: The research was conducted on male tennis players aged 13–14 (N = 239, participants of the World Junior Tennis Finals. From the methodological point of view, it was an intentional selection. The birth dates of individual tennis players were taken from official materials of the ITF, the research data were processed using Microsoft Excel. The personal data were processed with the approval of players and the hosting organization (ITF. RESULTS: Testing of the hypothesis on the significance of differences in the distribution of frequencies between individual quarters (Q1–Q4 has proved statistically relevant differences between Q1 and Q3, Q1 and Q4, Q2 and Q3, and Q2 and Q4; a statistically relevant difference has been also found in the distribution of frequencies between the first and second half of the year. On the basis of the results of the presented research, the age effect in the studied population of junior male tennis players can be regarded as significant. CONCLUSIONS: The results of the analysis of the research data confirm the conclusions of similar studies in other sports and prove that in the population of elite junior players

    Full Text Available Amputation is considered as a defect and its outcome is person's disability and the incidences of psychological problems. This study examined psychophysiological of disability in male mice with amputed limb. This experimental study was conducted on 30 male mice were randomly divided into 6 groups of 5 animals each: two intact control groups (NC, two groups  that their right hands (RH amputed from elbow joint and two other groups that their right feet (RF amputed from knee joint. Behavioral tests were performed in each group either after 30 or 60 days after amputation. To investigate the behavior paradigms, we used of forced swimming test for depression, elevated plus maze for anxiety, tail pinch test for stress, Morris water maze for spatial memory and object recognition test for learning. This study demonstrated that the immobility time in FST was RF group on day 30 significant increased compared to NC group on day 60. The open arms entries in EPM were significant decrease in RH and RF groups on days 30 and 60 compared to NC group on day 60. The time in closed arms in EPM was RF group on day 60 significant increased compared to NC group on day 30. RH and RF groups on days 30 and 60 significant increased in this parameter when compared to NC group on day 60. The time in open arms in EPM was significant different in NC group on day 30 as compared to NC group on day 60. RH and RF groups on days 30 and 60 significant decrease compared to NC group on day 60. To sum, limb amputation increased anxious behavior. The trend of working memory in ORT was deteriorated following limb amputation. The response to stress stimulus in TPT was increased post-amputation (P>0.05. The spatial memory in MWM also showed moderate deficit following amputation. Results from present study indicated that amputation can created some psychophysiological disorders. Major reason for which is probably animal's motor behavior defects, although further studies need to be done on

    Full Text Available Abstract Background Rates of suicide and undetermined death increased rapidly in Scotland in the 1980's and 1990's. The largest increases were in men, with a marked increase in rates in younger age groups. This was associated with an increase in hanging as a method of suicide. National suicide prevention work has identified young men as a priority group. Routinely collected national information suggested a decrease in suicide rates in younger men at the beginning of the 21st century. This study tested whether this was a significant change in trend, and whether it was associated with any change in hanging rates in young men. Methods Joinpoint regression was used to estimate annual percentage changes in age-specific rates of suicide and undetermined intent death, and to identify times when the trends changed significantly. Rates of deaths by method in 15 – 29 year old males and females were also examined to assess whether there had been any significant changes in method use in this age group. Results There was a 42% reduction in rates in 15 – 29 year old men, from 42.5/100,000 in 2000 to 24.5/100,000 in 2004. A joinpoint analysis confirmed that this was a significant change. There was also a significant change in trend in hanging in men in this age group, with a reduction in rates after 2000. No other male age group showed a significant change in trend over the period 1980 – 2004. There was a smaller reduction in suicide rates in women in the 15 – 29 year old age group, with a reduction in hanging from 2002. Conclusion There has been a reduction in suicide rates in men aged 15 – 29 years, and this is associated with a significant reduction in deaths by hanging in this age group. It is not clear whether this is related to a change in method preference, or an overall reduction in suicidal behaviour, and review of self-harm data will be required to investigate this further.

    During courtship, many animals, including insects, birds, fish, and mammals, utilize acoustic signals to transmit information about species identity. Although auditory communication is crucial across phyla, the neuronal and physiologic processes are poorly understood. Sound-evoked chaining behavior, a display of homosexual courtship behavior in Drosophila males, has long been used as an excellent model for analyzing auditory behavior responses, outcomes of acoustic perception and higher-order...

    Full Text Available In the present study a proteomics approach has been taken to analyze differential protein expression between mature male and sex reversed male of Nemacheilus angorae In regard to the fruitful studies of sex reversal in mammalian species and the fact that some major sex determination molecules are conserved among vertebrates, Nemacheilus angorae (Angorae loach seems to be a good model system in studying molecules involved in sex differentiation.N. angorae is a teleports fish exhibiting a spontaneous sex reversal (male to female pattern. The gonads of adult individuals were dissected and used for histological investigation and protein analysis. Proteins were next analyzed using two-dimensional gel electrophoresis and the distinguished spots have been compared in two experimental samples. Among them, 23 differentially expressed proteins spots were identified by MALDI-TOF/TOF analysis. Two spots in sex reversed testis with high score showed significant similarity to Vasa (assembling of the pole plasm and the pronuclear region of the oocyte and Proline 4-hydroxylase proteins. Vasa are involved in germ cell development both in invertebrates and vertebrates. This data could be considered as starting base for subsequent studies to identify proteins involved in sex reversal and differentiation at different stages of gonadal maturation in fish.

    The molecular pathways controlling gender are highly variable and have been identified in only a few nonmammalian model species. In many insects, maleness is conferred by a Y chromosome-linked M factor of unknown nature. We have isolated and characterized a gene, Yob, for the M factor in the malaria mosquito Anopheles gambiae Yob, activated at the beginning of zygotic transcription and expressed throughout a male's life, controls male-specific splicing of the doublesex gene. Silencing embryonic Yob expression is male-lethal, whereas ectopic embryonic delivery of Yob transcripts yields male-only broods. This female-killing property may be an invaluable tool for creation of conditional male-only transgenic Anopheles strains for malaria control programs. PMID:27365445

  3. Dosimetric evaluation in teletherapy for male breast cancer treatment

    International Nuclear Information System (INIS)

    The present study evaluated dose distribution in the male breast using thermoluminescent dosimeters (TLDs). The rate of male breast cancers has increased in recent years, due to the deficiency of preventive examinations (male mammography). Still, male breasts have smaller volumes than female breasts, thus, from the point of view of radiation protection, it is essential to monitor the doses received by the male breast, as well as those received by healthy and critical organs in order to evaluate radiotherapy performance and aid treatment planning. For this reason, the treatment of male breast cancer was simulated with the radiation by linear accelerator in Alderson Rando phantom and doses were measured with thermoluminescent dosimeters. The results of the treatment planning and measured were compared. (author)

    International Nuclear Information System (INIS)

    The dry seeds of the high yielding cultivar, Yuzhi-4, were irradiated with 300, 500 and 700 Gy of 60Co- gamma rays. 3277 M1 plants were harvested separately as single plants and also in bulk, by doses. In M2, the single plant seeds were grown in progeny rows and the bulked seeds were grown as bulks. 25 male sterile plants were screened from M2. 10 of the 25 male sterile plants were from the progenies of the single plant seeds and 15 were from the progenies of the bulked seeds. In further genetic research of the 25 male sterile plants in M3 and M4, 6 separate genic male sterile (GMS) lines were identified. Their male sterility was stable and was controlled by a pair of alleles, male fertility being dominant to sterility. (author)

  5. The cost of the sword: escape performance in male swordtails.

    Directory of Open Access Journals (Sweden)

    Alex Baumgartner

    Full Text Available The handicap theory of sexual selection posits that male display traits that are favored in mate choice come at a significant cost to performance. We tested one facet of this hypothesis in the green swordtail (Xiphophorus helleri. In this species, the lower ray of male caudal fin is extended into a 'sword', which serves to attract potential mates. However, bearing a long sword may increase drag and thus compromise a male's ability to swim effectively. We tested escape performance in this species by eliciting C-start escape responses, an instinctive escape behavior, in males with various sword lengths. We then removed males' swords and retested escape performance. We found no relationship between escape performance and sword length and no effect of sword removal on escape performance. While having a large sword may attract a predator's attention, our results suggest that sword size does not compromise a male's escape performance.

    In human evolution, social group living and Pavlovian fear conditioning have evolved as adaptive mechanisms promoting survival and reproductive success. The evolutionarily conserved hypothalamic peptide oxytocin is a key modulator of human sociality, but its effects on fear conditioning are still elusive. In the present randomized controlled study involving 97 healthy male subjects, we therefore employed functional magnetic resonance imaging and simultaneous skin conductance response (SCR) measures to characterize the modulatory influence of intranasal oxytocin (24 IU) on Pavlovian fear conditioning. We found that the peptide strengthened conditioning on both the behavioral and neural levels. Specifically, subjects exhibited faster task-related responses and enhanced SCRs to fear-associated stimuli in the late phase of conditioning, which was paralleled by heightened activity in cingulate cortex subregions in the absence of changes in amygdala function. This speaks against amygdalocentric views of oxytocin having pure anxiolytic-like effects. Instead, it suggests that the peptide enables extremely rapid and flexible adaptation to fear signals in social contexts, which may confer clear evolutionary advantages but could also elevate vulnerability for the pathological sequelae of interpersonal trauma.

    2015-12-01

    Arsenic is a toxic metalloid that exists ubiquitously in the environment, and affects global health problems due to its carcinogenicity. In most populations, the main source of arsenic exposure is the drinking water. In drinking water, chronic exposure to arsenic is associated with increased risks of various cancers including those of skin, lung, bladder, and liver, as well as numerous other non-cancer diseases including gastrointestinal and cardiovascular diseases, diabetes, and neurologic and cognitive problems. Recent emerging evidences suggest that arsenic exposure affects the reproductive and developmental toxicity. Prenatal exposure to inorganic arsenic causes adverse pregnancy outcomes and children's health problems. Some epidemiological studies have reported that arsenic exposure induces premature delivery, spontaneous abortion, and stillbirth. In animal studies, inorganic arsenic also causes fetal malformation, growth retardation, and fetal death. These toxic effects depend on dose, route and gestation periods of arsenic exposure. In males, inorganic arsenic causes reproductive dysfunctions including reductions of the testis weights, accessory sex organs weights, and epididymal sperm counts. In addition, inorganic arsenic exposure also induces alterations of spermatogenesis, reductions of testosterone and gonadotrophins, and disruptions of steroidogenesis. However, the reproductive and developmental problems following arsenic exposure are poorly understood, and the molecular mechanism of arsenic-induced reproductive toxicity remains unclear. Thus, we further investigated several possible mechanisms underlying arsenic-induced reproductive toxicity. PMID:26973968

    Full Text Available This paper presents a case study of women in the academic teaching profession in the context of the Criminal Police Academy, a Belgrade higher education institution of a typically male-dominant type. The aim of the paper is to describe and analyze women's current position and upward career mobility, as well as to discover the causes and mechanisms limiting their weaker (slower professional recognition. Multiple case method was deployed, on the basis of data collected from various sources: relevant literature on gender inequality of women in the academic profession, official documents of the institution in which the study was conducted, and personal life stories of women research subjects taken through in-depth semi-structured interviews. The results indicate that women who are part of a masculine climate in their academic teaching profession and in their personal life, are arguably in a subordinate position compared to men, and accept their position as quite natural. The research was limited to six typical cases, so that the conclusions may be generalized only with the greatest care; however, researchers who are interested in checking the study's objectivity and validity are provided with the adequate basis for further testing. The research shows that personal perspectives and testimonies of women can contribute to a deeper understanding of their disadvantage in academia, while at the same time contributing to the sociology of the 'individual' and the 'qualitative' by expanding the database on gender issues.

    2014-11-01

    The National Family Planning Programme of India had introduced condom as one of the family planning methods in the late 1960s. Condom was promoted as a family planning method through social marketing since its inception. With the increasing prevalence and incidence of sexually transmitted infections (STIs) including HIV/AIDS, condom was also promoted as a dual method for protection against both unintended pregnancies as well as sexually transmitted infections. Despite efforts at various levels, the overall use of condom among couples in India is low. Here we present literature review of studies to understand the condom acceptability among couples in India. Specifically, the paper assesses research and programmes that have been carried out to increase the use of condom among couples; determinants of condom use; reason for not using condom; and perception versus experience of condom failure. The reported problems related to condom use included non acceptance by partner, perceived ineffectiveness, less comfort, lack of sexual satisfaction, husband's alcohol use, depression, and anxiety, and not available at that instant. The role of media in the promotion of condom use was indicated as an important way to increase awareness and use. Multiple strategies would help in acceptance of male condom. PMID:25673537

    2014-10-01

    Older adults (≥60 years) perform worse than young adults (18-30 years) when recognizing facial expressions of emotion. The hypothesized cause of these changes might be declines in neurotransmitters that could affect information processing within the brain. In the present study, we examined the neuropeptide oxytocin that functions to increase neurotransmission. Research suggests that oxytocin benefits the emotion recognition of less socially able individuals. Men tend to have lower levels of oxytocin and older men tend to have worse emotion recognition than older women; therefore, there is reason to think that older men will be particularly likely to benefit from oxytocin. We examined this idea using a double-blind design, testing 68 older and 68 young adults randomly allocated to receive oxytocin nasal spray (20 international units) or placebo. Forty-five minutes afterward they completed an emotion recognition task assessing labeling accuracy for angry, disgusted, fearful, happy, neutral, and sad faces. Older males receiving oxytocin showed improved emotion recognition relative to those taking placebo. No differences were found for older females or young adults. We hypothesize that oxytocin facilitates emotion recognition by improving neurotransmission in the group with the worst emotion recognition. PMID:24856057

    Male homosexual preference (MHP) has long been of interest to scholars studying the evolution of human sexuality. Indeed, MHP is partially heritable, induces a reproductive cost and is common. MHP has thus been considered a Darwinian paradox. Several questions arise when MHP is considered in an evolutionary context. At what point did MHP appear in the human evolutionary history? Is MHP present in all human groups? How has MHP evolved, given that MHP is a reproductively costly trait? These questions were addressed here, using data from the anthropological and archaeological literature. Our detailed analysis of the available data challenges the common view of MHP being a "virtually universal" trait present in humans since prehistory. The conditions under which it is possible to affirm that MHP was present in past societies are discussed. Furthermore, using anthropological reports, the presence or absence of MHP was documented for 107 societies, allowing us to conclude that evidence of the absence of MHP is available for some societies. A recent evolutionary hypothesis has argued that social stratification together with hypergyny (the hypergyny hypothesis) are necessary conditions for the evolution of MHP. Here, the link between the level of stratification and the probability of observing MHP was tested using an unprecedented large dataset. Furthermore, the test was performed for the first time by controlling for the phylogenetic non-independence between societies. A positive relationship was observed between the level of social stratification and the probability of observing MHP, supporting the hypergyny hypothesis. PMID:26267276

    Full Text Available The National Family Planning Programme of India had introduced condom as one of the family planning methods in the late1960s. Condom was promoted as a family planning method through social marketing since its inception. With the increasing prevalence and incidence of sexually transmitted infections (STIs including HIV/AIDS, condom was also promoted as a dual method for protection against both unintended pregnancies as well as sexually transmitted infections. Despite efforts at various levels, the overall use of condom among couples in India is low. Here we present literature review of studies to understand the condom acceptability among couples in India. Specifically, the paper assesses research and programmes that have been carried out to increase the use of condom among couples; determinants of condom use; reason for not using condom; and perception versus experience of condom failure. The reported problems related to condom use included non acceptance by partner, perceived ineffectiveness, less comfort, lack of sexual satisfaction, husband′s alcohol use, depression, and anxiety, and not available at that instant. The role of media in the promotion of condom use was indicated as an important way to increase awareness and use. Multiple strategies would help in acceptance of male condom.

    Many aspects of fertility rely on intact neurologic function and thus neurologic diseases can result in infertility. While research into general female fertility and alterations in male semen quality is limited, we have an abundance of knowledge regarding ejaculatory dysfunction following nerve injury. Normal ejaculation is the result of coordinated reflex activity involving both the sympathetic and somatic nervous systems. Nerve injury can result in retrograde ejaculation, and anejaculation. With retrograde ejaculation, the ejaculate is propelled into the bladder instead of out through the urethra. In mild cases this condition can be reversed by sympathomimetic medications and, in more severe cases, sperm cells can be extracted from the bladder following ejaculation. With anejaculation, the ejaculatory reflex is not activated by normal sexual stimulation. In such cases, the first choice of treatment is assisted ejaculation, preferably by penile vibratory stimulation. If vibratory stimulation is unsuccessful, then ejaculation can almost always be induced by electroejaculation. In cases where assisted ejaculation fails, sperm can be retrieved surgically from either the epididymis or from the testis. Once viable sperm cells have been obtained, these are used in assisted reproductive techniques, including intravaginal insemination, intrauterine insemination, and in vitro fertilization/intracytoplasmic sperm injection.

    Full Text Available Objective: The objective of the present study was to verify if there is any relation between diabetes mellitus and male infertility. Methods: the spermograms of 43 non-diabetic subjects and 12 diabetic patients (type 1 and 2 aged 20-60 years were compared. Spermiological findings in diabetic patients were compared with those of normal individuals of the same age. Serum testosterone, prolactin, follicle-stimulant hormone, luteinizing hormone, glucose and glycosilated hemoglobin were assayed in diabetic patients. Rresults: Six diabetic patients (four type 1 and two type 2 presented chronic complications attributed to neuropathy and vascular insufficiency. No difference was observed in the semen characteristics (odor, color, viscosity and pH between the control group and the diabetic patients. There were no differences between seminal concentrations and percentage of motile spermatozoa during the first hour of observation in the two groups (p < 0.05. Impotence was reported by four diabetic patients (33.3%. Erectile failure was associated with diabetic microangiopathy and neuropathy. There were no controls with impotence. No significant hormonal changes were found in the diabetic patients. Cconclusions: The present results suggest that neuropathy and vascular insufficiency  may be  implicated in sexual dysfunction in type 1 and 2 diabetic patients, without significantly affecting the hypothalamic-pituitary-gonadal axis.

    Full Text Available The purpose of this study was to compare the serum levels of androgens between hyposexual and non-hyposexual patients with epilepsy. Adult male patients with epilepsy were investigated. Serum levels of testosterone (T and free-T, estradiol, and sex hormone binding globulin (SHBG were measured and the free androgen index (FAI was calculated. While there were no differences between hyposexual and non-hyposexual patients in the serum levels of T, free-T, and estradiol, or to the FAI, the serum levels of SHBG were significantly higher in hyposexual patients than in non-hyposexual patients. Thus, the effects of increased SHBG upon serum levels of testosterone biologically active in patients with epilepsy and hyposexuality were not detected by the methods used in this study. Four (44% of nine hyposexual patients who were re-evaluated after two years follow-up improved sexual performance. Thus, clinical treatment that results in good seizure control may improve sexual performance in some patients with epilepsy.

  17. Male infertility in spinal cord trauma

    Full Text Available Every year there are 10 thousand new cases of patients victimized by spinal cord trauma (SCT in the United States and it is estimated that there are 7 thousand new cases in Brazil. Eighty percent of patients are fertile males. Infertility in this patient group is due to 3 main factors resulting from spinal cord lesions: erectile dysfunction, ejaculatory disorder and low sperm counts. Erectile dysfunction has been successfully treated with oral and injectable medications, use of vacuum devices and penile prosthesis implants. The technological improvement in penile vibratory stimulation devices (PVS and rectal probe electro-ejaculation (RPE has made such procedures safer and accessible to patients with ejaculatory dysfunction. Despite the normal number of spermatozoa found in semen of spinal cord-injured patients, their motility is abnormal. This change does not seem to be related to changes in scrotal thermal regulation, frequency of ejaculation or duration of spinal cord damage but to factors related to the seminal plasma. Despite the poor seminal quality, increasingly more men with SCT have become fathers through techniques ranging from simple homologous insemination to sophisticated assisted reproduction techniques such as intracytoplasmic sperm injection (ICSI.

    The influence of sex difference on symptoms, behavior during illness, the interactional dynamics of conflict, and external society reality is studied here in two random samples of 615 and 739 patients who sought psychotherapeutic treatment. The comparison shows that greater importance is attached to interpersonal relations and social reality (early marriage with child, separation, divorce) as well as to coming to terms with these things emotionally among women, who were in the majority in all clinical studies. Women often fall ill because of difficult relationships from which they cannot free themselves inwardly and toward which the remain oriented with disappointment and complaints, even after actual separation. A stronger need for close personal relationships leads them (often against the background of a conflict-ridden parental family) to an early partnership that is often cemented by pregnancy, only to be dissolved later by divorce. The counter-image of such relational problems is more often found among male patients, who show difficulties in limiting their own autonomy and in establishing dependable emotional ties and social relations. The relationships between the different realities of the two sexes, the structure of their needs and the resulting predilection to illness are examined in detail. PMID:2763723

    Full Text Available Over the last two decades RISUG has been drawing attention in the field of male contraception. It promises to sterile men for a period of up to 10-15 years. According to recent studies in animal models, it proves to be completely reversible. Practically, there are no better options available that can assure complete sterility and precise reversibility. Regardless of so much of information available, RISUG is still holding up for many reasons, firstly, the available information engender bewilderment such as what is this copolymer, how does it work and is reversal really possible? Secondly, advancement of this outstanding invention is drastically slow and thirdly, effects of long-term contraception with RISUG and reports on evaluation of anomalies (if any in F 1 , F 2 progenies, are lacking. In this review the lacunae as well as advances in the development of RISUG in the light of published work and available resources are pointed out. Formulation of the RISUG, its mode of action and clinical trials have been addressed with particular emphasis.

  20. Disposition of citral in male Fischer rats

    International Nuclear Information System (INIS)

    The disposition of citral, an essential oil occurring in many foods and fragrances, was studied in male Fischer rats after iv, po, and dermal treatments. The pattern of distribution and elimination was the same after iv or oral exposure. Urine was the major route of elimination of citral-derived radioactivity, followed by feces, 14CO2, and expired volatiles. However, after dermal exposure, relatively less of the material was eliminated in the urine and more in the feces, suggesting a role for first-pass metabolism through the skin. Citral was almost completely absorbed orally; due to its extreme volatility, much of an applied dermal dose was lost. The citral remaining on the skin was fairly well absorbed. No effect of oral dose, from 5 to 500 mg/kg, was detected on disposition. Although the feces was a minor route of excretion, approximately 25% of the administered dose was eliminated via the bile within 4 hr of an iv dose. The metabolism of citral was both rapid and extensive. Within 5 min of an iv dose, no unmetabolized citral could be detected in the blood. Repeated exposure to citral resulted in an increase in biliary elimination, without any significant change in the pattern of urinary, fecal, or exhaled excretion. This suggests that citral may induce at least one pathway of its own metabolism. The rapid metabolism and excretion of this compound suggest that significant bioaccumulation of citral would not occur
