    A review of case material (1970-1987) from the Mayo Clinic revealed a variety of seminal vesicle abnormalities (and associated genitourinary anomalies). Sixteen cases of congenital seminal vesicle cysts were studied. Ipsilateral renal agenesis or dysgenesis was associated with 11 of the 16 cases. Other associated genitourinary anomalies included ipsilateral ureteral ectopy, agenesis of the vas deferens, and cryptorchidism. Diagnostic imaging studies were reviewed and the results tabulated. The spectrum of urographic and surgical findings in patients is presented and compared with those in cases previously reported in the literature

    PURPOSE: Adult polycystic kidney disease (APKCD), an autosomal dominant disorder, causes cyst formation in the kidney, liver, pancreas, esophagus, ovaries, uterus, and brain. This paper describes four APKCD patients with CT evidence of seminal vesicle cysts (SVCs). Four patients (aged 45-65 years) underwent abdominal/pelvic CT with oral and intravenous contrast material. Three were evaluated for possible renal transplantation and one for sepsis material. All seminal vesicles contained cystic masses with fluid that measured between 0 and 30 HU. Seminal vesicle thickness was 3-4 cm (normal, 1.5 cm). High-density walls separated the 3-12-mm diameter cysts. All patients demonstrated typical renal stigmata of APKCD. One patient had hepatic cysts, and none had cysts elsewhere. Postmortem examination in one patient confirmed the SVCs

    Full Text Available Primary tumors of the seminal vesicle are extremely rare. Among them, there is a spectrum of tumors derived from both epithelium and stroma and so classified as epithelial-stromal tumors. Herein, we report a case of a cystadenoma in a 49-year-old asymptomatic man, detected in a routine ultrasonography for liver disease follow-up. The digital rectal examination detected a large mass anterior to rectum and posterior to bladder. Computed tomography scan and magnetic resonance imaging showed a normal prostate and a 9.0 cm cystic tumor, replacing the left seminal vesicle. The gross appearance and microscopic aspect was compatible with cystadenoma of seminal vesicle. Patient's postoperative recovery was uneventful. He is currently alive, 3 years after the diagnosis, with no signs of recurrence.

    Full Text Available Herein is a case of a 23-year-old man with recurrence of a seminal vesicle cyst after percutaneous drainage and laparoscopic excision complicated by hemorrhage requiring embolization. He presented to the emergency department for pain after ejaculation. Computed tomographic scan of his pelvis revealed extravasation of contrast near his cyst and pelvic fluid collection suspicious for a hematoma. The patient had steadily decreasing hemoglobin and hematocrit levels. An interventional radiologist performed an embolization of the left seminal vesicle cystic arteries. Hemoglobin and hematocrit values improved and he was discharged. Hemorrhage resolved with embolization procedure and pain dissipated over the course of follow up care.

    Terrone, C; Ceratti, G; Bonazzi, A; Rocca Rossetti, S; Bianchi, M

    1996-12-01

    About 10% of the cases of male infertility is represented by the obstruction of the seminal tract, which may be congenital or secondary to inflammatory events or surgery. The most frequent obstructive malformation of the seminal tract is the bilateral agenesia of the vas deferens. Such malformation is typical of the cystic fibrosis (CF), an autosomal recessive disorder determining chronic respiratory infections with bronchiectasia, and pancreatic failure. Recently the defective gene responsible for CF has been identified on the long arm of the chromosome 7. Congenital bilateral absence of the vas deferens (CBAVD) may be present in otherwise healthy males without clinical evidence of CF. Genetics studies demonstrated that most CBAVD display at least one detectable CF mutation, therefore this disease can be considered as an incomplete clinical form of CF. With the realization that a man with CBAVD may have CF, albeit a genital form, considerable care is required not only to document his specific mutations, but also to test his partner for CF mutations to evaluate the risk that their child would have CF. The association of chronic suppurating respiratory disease with obstructive azoospermia characterizes also the Young's syndrome. In this disease the obstruction could possibly be the result of defective epididymal sperm transport, related to an abnormality in the mucus. Despite some clinical common aspects, CF and Young's syndrome are two distinct entity. In fact, no CF mutations have been demonstrated in Young's syndrome. Congenital obstructive abnormalities of the vas deferens and epididymis are often associate to cryptorchidism (36-68% of the cases) and to patent processus vaginalis. The degree of testicular retention and processus vaginalis closure correlates well with the incidence of associated epididymal defects. Rare causes of congenital obstructive azoospermia are represent by the cyst of Müllerian or Wolffian origin. An obstruction to the progression of the

    The involvement of seminal vesicles in prostate cancer can affect the prognosis and determine the treatment. The objective of this study was to determine whether we could predict its infiltration at the time of the prostate biopsy to know when to indicate the biopsy of the seminal vesicles. observational retrospective study of 466 patients who underwent seminal vesicle biopsy. The indication for this biopsy was a prostate-specific antigen (PSA) level greater than 10 ng/ml or an asymmetric or obliterated prostatoseminal angle. The following variables were included in the analysis: PSA level, PSA density, prostate volume, number of cores biopsied, suspicious rectal examination, and preservation of the prostatoseminal angle, studying its relationship with the involvement of the seminal vesicles. Forty-one patients (8.8%) had infiltrated seminal vesicles and 425 (91.2%) had no involvement. In the univariate analysis, the cases with infiltration had a higher mean PSA level (P 19.60 ng/dL (P < .01) and 2.95 times higher if there is a suspicious rectal examination (P = .014). Furthermore, this probability increases by 1.04 times for each unit of prostate volume lower (P < .01). The ROC curves showed maximum sensitivity and specificity at 19.6 ng/mL for PSA and 0.39 for PSA density. In this series, greater involvement of seminal vesicles was associated with a PSA level ≥20 ng/ml, a suspicious rectal examination and a lack of prostatoseminal angle preservation.

    Durupt, S; Nove Josserand, R; Durieu, I

    2014-06-01

    We present the recent therapeutic advances in the cystic fibrosis care. It concerns improvements in symptomatic treatment with the development of dry powder inhaled antibiotics that improved quality of life, and innovative treatments namely the modulators of the cystic fibrosis transmembrane protein conductance regulator (CFTR), molecules which act specifically at the level of the defective mechanisms implied in the disease. The life expectancy of cystic fibrosis patients born after 2000, is estimated now to be about 50 years. This improvement of survival was obtained with the organization of the care within the specialized centers for cystic fibrosis (Centre de ressource et de compétences de la mucoviscidose) and remains still based on heavy symptomatic treatments. Dry powder inhaled antibiotics constitute a significant time saving for patients to whom all the care can achieve two hours daily. Since 2012, the modulators of CFTR, molecules allowing a pharmacological approach targeted according to the type of the mutations, allows a more specific approach of the disease. Ivacaftor (Kalydeco(®)) which potentialises the function of the CFTR protein expressed on the cellular surface is now available for patients with the G551D mutation. Lumacaftor is going to be tested in association with ivacaftor in patients with the F508del mutation, that is present in at least 75% of the patients. The ataluren which allows the production of a functional protein CFTR in patients with a no sense mutation is the third representing of this new therapeutic class. We presently have numerous symptomatic treatments for the cystic fibrosis care. The development of CFTR modulators, today available to a restricted number of patients treated with ivacaftor represents a very promising therapeutic avenue. It will represent probably the first step to a personalized treatment according to CFTR genotype. Copyright © 2013 Société nationale française de médecine interne (SNFMI). Published by

    Sublett, J Wesley; Bernstein, Jonathan A

    2011-01-01

    Seminal plasma hypersensitivity manifests as a spectrum of systemic and/or localized clinical symptoms after exposure to specific protein components in seminal fluid. The prevalence of this disease is largely unknown, but it is believed to affect up to 40,000 women in the United States. Although no definitive risk factors have been confirmed, women with systemic reactions are frequently atopic. Prostate-specific antigen is believed to be the major allergen involved in the disorder, but other proteins are likely involved. Interestingly, up to 40%-50% of both systemic and localized seminal plasma hypersensitivity cases can occur after first-time intercourse. Diagnosis is based on clinical history. The gold standard for diagnosing seminal plasma hypersensitivity is prevention of symptoms with the use of a condom. Patients with seminal plasma hypersensitivity demonstrate positive prick skin test and/or serum-specific immunoglobulin E to whole seminal fluid or fractionated seminal plasma proteins. Treatment of seminal plasma hypersensitivity involves either avoidance with the use of condoms, intravaginal graded challenge using dilutions of whole seminal fluid, or subcutaneous desensitization to relevant fractionated seminal plasma proteins obtained from the woman's sexual partner. In most cases, treatment using one or more of the above approaches has been very successful. Infertility has not been demonstrated to be directly related to seminal plasma hypersensitivity, although women with the condition frequently have difficulty conceiving due to their inability to have unprotected sexual intercourse. © 2011 Mount Sinai School of Medicine.

    To describe the epidemiological, physiopathological, clinical and therapeutic knowledge concerning cystic fibrosis (CF). Important modifications in the health organization of the care concerning this orphan disease have been implemented in France. The life expectancy has dramatically increased, as well as the knowledge concerning the pathological structure and function of the CFTR gene and protein. This will lead to the development of emerging drug treatments for this lethal disease. The life expectancy is predicted to exceed 40 years for children born in the 2000s. As a result, there has been a tremendous growth of the adult population that reached 40% of the overall approximately 5000 patients included in the CF French registry (Observatoire National de la Mucoviscidose). Lung disease remains the primary cause of morbidity and mortality. The characteristic phenotypic presentation associates bronchial and rhinosinusal symptoms, pancreatic insufficiency and liver disease. Bronchial damage leads to progressive chronic respiratory insufficiency. Diabetes mellitus and osteoporosis frequently appears in adulthood. Neonatal screening has been implemented in France since 2002. It will prevent delayed diagnosis and its deleterious consequences. Some atypical cases of CF presenting only with one or two organ system involvement can be diagnosed in adulthood. Isolated chronic rhinosinusitis, bronchiectasis, congenital bilateral absence of vas deferens, recurrent pancreatitis, allergic bronchopulmonary aspergillosis, and some case of cholangitis may so revealed late form of cystic fibrosis. The health care is organized in cystic fibrosis centres. Despite gene discovery, treatment still remains symptomatic, based on intensive pulmonary and nutritional treatments. Challenges for new treatments are to correct the basic defect, either by gene therapy or by pharmacological modulation of the abnormal physiological processes.

    Full Text Available Seminal fluid proteins show striking effects on reproduction, involving manipulation of female behavior and physiology, mechanisms of sperm competition, and pathogen defense. Strong adaptive pressures are expected for such manifestations of sexual selection and host defense, but the extent of positive selection in seminal fluid proteins from divergent taxa is unknown. We identified adaptive evolution in primate seminal proteins using genomic resources in a tissue-specific study. We found extensive signatures of positive selection when comparing 161 human seminal fluid proteins and 2,858 prostate-expressed genes to those in chimpanzee. Seven of eight outstanding genes yielded statistically significant evidence of positive selection when analyzed in divergent primates. Functional clues were gained through divergent analysis, including several cases of species-specific loss of function in copulatory plug genes, and statistically significant spatial clustering of positively selected sites near the active site of kallikrein 2. This study reveals previously unidentified positive selection in seven primate seminal proteins, and when considered with findings in Drosophila, indicates that extensive positive selection is found in seminal fluid across divergent taxonomic groups.

    Edson, S.B.; Hricak, H.; Chun-Fang Chang, Y.

    1987-01-01

    The seminal vesicles of 56 healthy males and 23 males with pathologic conditions were studied with a .35-T magnet and spin-echo (SE) techniques (repetition time/echo time [msec] = 500/30 and 2,000/60). The authors analyzed (1) the size and relative signal intensity of seminal vesicles compared to surrounding fat, muscle, or urine; (2) the effect of aging on the size and signal intensity of the vesicles, and (3) the appearance of the seminal vesicles in different pathologic conditions. In the transverse plane, the normal seminal vesicle measures 31 +- 7 mm in length and 17 +- 4 mm in width. Its size or signal intensity did not change significantly with age. On SE = 500/30 images the seminal vesicles were isointense with muscle; on SE = 2,000/60 images they were isointense or slightly hypointense relative to fat. MR imaging was highly sensitive for displaying seminal vesicle pathology, based on asymmetry in size and changes in signal intensities. MR imaging provides unique information but its role in pathologic conditions needs to be further explored

    Cystic meningiomas are rare. A 60-year-old housewife was admitted because of headache and left hemiparesis. An enhanced CT scan revealed a high-density area in the right frontotemporal region, while several well-circumscribed low-density areas were seen in the high-density area. Angiography showed a sun-burst appearance fed by the middle meningeal artery. At surgery, xanthochromic fluid was aspirated and the tumor was removed completely. The pathohistological finding was meningothelial meningioma with an intratumoral cyst. There were variable-sized vacuoles among the tumor cells, and there were some tumor cells with intracytoplasmic fat-stain-positive granules. We speculated that the mechanism of cyst formation is as follows: in the first step, far droplets are stored in the tumor cells; the numbers and/or sizes of the fats gradually increase, and then the intracytoplasmic fats disappear by an unknown mechanism and these cells become vacuoles. In the second step, these vacuoles fuse to microcysts, and the microcysts fuse to macrocysts. (author)

    Acid neutralization during chemical clearance is significantly prolonged in children with cystic fibrosis, compared to symptomatic children without cystic fibrosis. The absence of available reference values impeded identification of abnormal findings within individual patients with and without cystic fibrosis. The present study aimed to test the hypothesis that significantly more children with cystic fibrosis have acid neutralization durations during chemical clearance that fall outside the physiological range. Published reference value for acid neutralization duration during chemical clearance (determined using combined impedance/pH monitoring) was used to assess esophageal acid neutralization efficiency during chemical clearance in 16 children with cystic fibrosis (3 to cystic fibrosis. Duration of acid neutralization during chemical clearance exceeded the upper end of the physiological range in 9 of 16 (56.3%) children with and in 3 of 16 (18.8%) children without cystic fibrosis ( p =0.0412). The likelihood ratio for duration indicated that children with cystic fibrosis are 2.1-times more likely to have abnormal acid neutralization during chemical clearance, and children with abnormal acid neutralization during chemical clearance are 1.5-times more likely to have cystic fibrosis. Significantly more (but not all) children with cystic fibrosis have abnormally prolonged esophageal clearance of acid. Children with cystic fibrosis are more likely to have abnormal acid neutralization during chemical clearance. Additional studies involving larger sample sizes are needed to address the importance of genotype, esophageal motility, composition and volume of saliva, and gastric acidity on acid neutralization efficiency in cystic fibrosis children.

    Cystic fibrosis is an autosomal recessive genetic disease. Among Caucasians, it is the most common cause of pulmonary insufficiency during the first three decades of life. The prevalence of cystic fibrosis varies according to ethnic origin: it is common among Caucasians but rare among Asians. We report a case in which cystic fibrosis with bronchiectasis and hyperaeration was revealed by high-resolution CT, and mutation of the cystic fibrosis conductance transmembrane regulator gene (CFTR) by DNA analysis

    Full Text Available Primary adenocarcinoma of the seminal vesicle is a rare condition with only about 60 cases described in the literature. The unusual characteristics of this disease makes diagnosis difficult and treatment strategies differ as there are no specific guidelines available. This report presents a case of adenocarcinoma of the seminal vesicle with lung metastases in which surgical and chemotherapeutic treatments have been carried out. The MVAC dose dense regimen following local resection seems effective in this scenario and may be used in the treatment of this disease.

    Varicocele has been associated with decrease in seminal parameters. Selenium (Se), copper (Cu), and zinc (Zn) are trace elements essential for normal spermatogenesis of mammals and play a critical role as antioxidant defense system enzymes. Se, Cu, and Zn are associated with sperm quality in fertile and infertile men. However, there is little information about Se, Cu, and Zn concentrations in semen in patients with varicocele and its association with seminal parameters. The purpose of this study was to determine the concentrations of Se, Cu, and Zn in semen of patients with varicocele and the relationship with seminal parameters. Total Reflection X-Ray Fluorescence was used for the fist time in the seminal fluid analysis. The concentration of selenium in men with varicocele was smaller than the normozoospermic group, while no differences were observed for both concentrations of zinc and copper. A significant positive correlation between zinc and selenium concentration was observed. Selenium in seminal plasma correlates with a good spermatozoa concentrations, motility, and morphology. Additionally, a significant positive correlation was observed between zinc levels and sperm count. In conclusion, a decrease in selenium concentration was associated with detriment of seminal parameters. A study should be conducted to evaluate the benefits of both zinc and selenium supplementation to improve seminal parameters in patients with varicocele.

    Congenital seminal vesicle cysts associated with ipsilateral renal agenesis or dysplasia are rare malformations. Even though they are more often diagnosed today due to the introduction of advanced, sectional imaging techniques as CT and MRI, no reliable data about the prevalence of this malformation are available. This study reports seven consecutive cases, with long-term follow-up in five cases (26-119 months, mean 52 months). All patients underwent sonography, excretory urography, CT and MRI. Only two of seven patients presented nonspecific symptoms of the lower urinary tract; five were asymptomatic. In all cases sonography revealed the cystic character of the retrovesical enlargement. The anatomy of the lower pelvis was most accurately shown on MRI, which depicted the ectopic insertion of the ureter into the seminal vesicle in five cases. Cysts demonstrated high signal intensities in T1- and T2-weighted spin-echo images. In five cases the CT density was over 40 HU. Whereas one patient (15 years) presented significant enlargement of the cysts 10 years after primary diagnosis with compression of the urinary bladder, four patients showed no changes of their malformation in the follow-up examinations. The present data therefore support the concept of treating only symptomatic patients. (orig.)

    Reduction of lung inflammation is one of the goals of cystic fibrosis therapy. Inhaled corticosteroids are often used to treat children and adults with cystic fibrosis. The rationale for this is their potential to reduce lung damage arising from inflammation, as well as their effect on symptomatic wheezing. It is important to establish the current level of evidence for the risks and benefits of inhaled corticosteroids, especially in the light of their known adverse effects on growth. This is an update of a previously published review. To assess the effectiveness of taking regular inhaled corticosteroids, compared to not taking them, in children and adults with cystic fibrosis. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register, comprising references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings. We requested information from pharmaceutical companies manufacturing inhaled corticosteroids and authors of identified trials.Date of most recent search of the Group's Trials Register: 15 August 2016. Randomised or quasi-randomised trials, published and unpublished, comparing inhaled corticosteroids to placebo or standard treatment in individuals with cystic fibrosis. Two independent authors assessed methodological quality and risk of bias in trials using established criteria and extracted data using standard pro formas. The searches identified 34 citations, of which 26 (representing 13 trials) were eligible for inclusion. These 13 trials reported the use of inhaled corticosteroids in 506 people with cystic fibrosis aged between six and 55 years. One was a withdrawal trial in individuals who were already taking inhaled corticosteroids. Methodological quality and risk of bias were difficult to assess from published information. Many of the risk of bias judgements were unclear due to a lack of available information. Only two trials specified how

    The diagnosis of cystic fibrosis (CF) has evolved over the past decade as newborn screening has become universal in the United States and elsewhere. The heterogeneity of phenotypes associated with CF transmembrane conductance regulator (CFTR) dysfunction and mutations in the CFTR gene has become clearer, ranging from classic pancreatic-insufficient CF to manifestations in only 1 organ system to indeterminate diagnoses identified by newborn screening. The tools available for diagnosis have also expanded. This article reviews the newest diagnostic criteria for CF, newborn screening, prenatal screening and diagnosis, and indeterminate diagnoses in newborn-screened infants and symptomatic adults.

    More than 20 years after the gene discovery, without specific treatment, the observed improvement of the cystic fibrosis prognosis appears due to management's organization as well as early diagnosis (neonatal screening) or progress in symptomatic treatment. The CF Centers (CRCM) official recognition was a necessary step before generalization of routine neonatal screening (October, 2002). Actually French CF management relies on three levels of organization: CF centers, regional care networks and French CF Society, in close relationship with patients association (Vaincre la Mucoviscidose).

    Full Text Available Cystic kidney disease is an important cause of chronic renal failure. Since the utili-zation of imaging techniques in the diagnosis of diseases has become widespread, cystic kidney disease is now being increasingly diagnosed. This study is designed to determine the prevalence and pattern of cystic kidney disease at the Nephrology Unit of University of Ilorin Teaching Hospital (UITH, Ilorin. All consecutive adult patients seen in the Nephrology Unit of UITH during a ten-year period (January 1999-December 2008 were studied for the presence of cystic kidney disease. The results were analyzed with specific reference to age, gender, annual inci-dence, type of cystic disease, location of cyst, mode of presentation, complications and prognosis. A total of 67 out of 436 renal patients (15.4% studied had cystic kidney disease. A progressive annual increase in the number of cases was noticed. The age-range was 20-83 years with a mean of 47.4 +/- 16.2 years and the peak incidence was in the third and sixth decades with male to female ratio of 1.3:1. The types of cystic kidney disease identified in the study were: 26 simple cysts (38.8%, 35 polycystic kidney disease (53.3% and six multicystic kidney disease (8.9%. The most common mode of presentation was abdominal pain followed by hypertension, urinary tract infection, chronic renal failure and palpable abdominal mass, in decreasing order. Our study indicates that cystic kidney disease is not an uncommon problem among our renal patients and the incidence is on the increase. Although, routine screening of family members with cystic kidney disease still remains a contentious issue because the knowledge may evoke anxiety in terms of employment and insurance, screening of symptomatic cases or those that develop hypertension, hematuria and proteinuria is strongly recommended.

    Seminal plasma represents a unique environment for maturation, nutrition, and protection of male germ cells from damaging agents. It contains an array of organic as well as inorganic chemicals, encompassing a number of biologically and immunologically active compounds, including hormones. Seminal plasma contains also various pollutants transferred from outer environment known as endocrine disruptors. They interfere with hormones at the receptor level, act as inhibitors of their biosynthesis, and affect hormone regulation.In this minireview, the main groups of hormones detected in seminal plasma are summarized. Seminal gonadal steroids were investigated mostly with aim to use them as biomarkers of impaired spermatogenesis (sperm count, motility, morphology). Concentrations of hormones in the seminal plasma often differ considerably from the blood plasma levels in dependence on their origin. In some instances (dihydrotestosterone, estradiol), their informative value is higher than determination in blood.Out of peptide hormones detected in seminal plasma, peptides of transforming growth factor beta family, especially antimullerian hormone, and oligopeptides related to thyrotropin releasing hormone have the high informative value, while assessment of seminal gonadotropins and prolactin does not bring advantage over determination in blood.Though there is a large body of information about the endocrine disruptors' impact on male reproduction, especially with their potential role in decline of male reproductive functions within the last decades, there are only scarce reports on their presence in seminal plasma. Herein, the main groups of endocrine disruptors found in seminal plasma are reviewed, and the use of their determination for investigation of fertility disorders is discussed.

  15. Lactoferrin binding molecules in human seminal plasma.

    During ejaculation, the iron binding protein lactoferrin binds to sperm and forms a major component of sperm-coating antigens. Physicochemical properties of lactoferrin in seminal plasma (SP) and on sperm differ from those of purified lactoferrin. These differences have been attributed to the binding of unknown seminal macromolecules to lactoferrin. We have studied lactoferrin binding molecules in SP. The SP samples were coated onto microtiter plates and tested for binding of biotinylated lactoferrin. SP was found to specifically bind biotinylated lactoferrin. This binding was competitively inhibited by coincubation with unlabeled lactoferrin but was not affected by control incubations done with human IgG or transferrin. Lactoferrin binding molecules in SP were biochemically characterized by using SDS-PAGE and ligand blotting. Biotinylated lactoferrin bound to SP molecules of approximately 120, 60 and 30 kDa. No binding was observed with biotinylated transferrin. The presence of molecules that associate with lactoferrin in SP was further studied by using crossed immunoelectrophoresis. Lactoferrin in SP immunoprecipitated as two peaks, one of which corresponded to purified lactoferrin. These results suggest that some lactoferrin molecules in SP are free and that others are associated with lactoferrin binding molecules. Binding of lactoferrin to lactoferrin binding molecules appears to change its physicochemical properties and thus could influence its biologic activity and its affinity to sperm.

    Fewer than 40 cases of primary pleural synovial sarcoma have been reported so far with only 3 cases of cystic synovial sarcoma including cases originating from sites other than the pleura. Here, we present an exceedingly rare case of cystic synovial sarcoma originating from the mediastinal side of the visceral pleura in a 25-year man presenting with hemoptysis. On contrast-enhanced computed tomography (CT), cystic synovial sarcoma and cystic thymoma were difficult to be distinguished due to mediastinal location. Histopathological examination showed spindled morphology of tumor cells with hypercellularity and nuclear atypia. As these features are associated with both monophasic fibrous synovial sarcoma and type Athymoma, immunohistochemistry was performed. Adiagnosis of synovial sarcoma was confirmed by detection of CD99 and EMAand negativity of other markers. Fluorescence in situhybridization (FISH) was not done. Surgical excision was done and followed by oncology referral.

    Although the iron-chelating protein lactoferrin is secreted by the seminal vesicles, the precise role of lactoferrin in semen is unclear. This study aimed to determine whether there is any association between seminal lactoferrin concentrations and normal and abnormal semen samples with and without leucocytospermia. Lactoferrin concentrations were measured by radial immunodiffusion of semen samples from 368 men attending a regional andrology referral center. Routine seminal analysis, including the presence of leucocytospermia, was also performed. Results showed increased seminal lactoferrin in samples showing oligospermia (13.3 mg/100 ml) and oligoasthenospermia (13.4 mg/100 ml) compared to normospermic samples (11.2 mg/100 ml). There were no significant differences in seminal lactoferrin between normospermic samples and azoospermic samples or asthenospermic samples with normal sperm density. Although there was a trend toward increased lactoferrin concentration with leucocytospermia, this was not significant. Possible causes for raised lactoferrin in association with oligospermia are discussed.

    2017-07-01

    Full Text Available Cystic nephroma is a rare, benign multicystic lesion of the kidney. This tumor occurs both in children and in adults. In children, it is highly prevalent in males; in adults, it is more frequent in women. The term “cystic nephroma” represents two apparently different entities: pediatric cystic nephroma, a benign form thought to originate from metanephric tissue, and adult cystic nephroma, considered as a lesion of mixed epithelial stromal tumor. The clinical presentation may be a palpable mass or nonspecific symptoms such as abdominal pain, hematuria, and urinary tract infections. In this review, we summarize the ultrasound imaging features of cystic nephroma and describe the characteristics of the most common renal cystic lesions and the differential diagnosis of cystic nephroma with other renal cystic lesions.

    Flavia Angélica Ferreira Francisco

    2015-12-01

    Full Text Available Multiple cystic lung disease represents a diverse group of uncommon disorders that can present a diagnostic challenge due to the increasing number of diseases associated with this presentation. High-resolution computed tomography of the chest helps to define the morphological aspects and distribution of lung cysts, as well as associated findings. The combination of appearance upon imaging and clinical features, together with extrapulmonary manifestations, when present, permits confident and accurate diagnosis of the majority of these diseases without recourse to open-lung biopsy. The main diseases in this group that are discussed in this review are lymphangioleiomyomatosis, pulmonary Langerhans cell histiocytosis and folliculin gene-associated syndrome (Birt–Hogg–Dubé; other rare causes of cystic lung disease, including cystic metastasis of sarcoma, are also discussed. Disease progression is unpredictable, and understanding of the complications of cystic lung disease and their appearance during evolution of the disease are essential for management. Correlation of disease evolution and clinical context with chest imaging findings provides important clues for defining the underlying nature of cystic lung disease, and guides diagnostic evaluation and management.

    This study analyses seminal vesicle displacement relative to the prostate and in relation to treatment time. A group of eleven patients undergoing prostate cancer radiotherapy were imaged with a continuous 3 T cine-MRI in the standard treatment setup position. Four images were recorded every 4 seconds for 15 minutes in the sagittal plane and every 6.5 seconds for 12 minutes in the coronal plane. The prostate gland and seminal vesicles were contoured on each MRI image. The coordinates of the centroid of the prostate and seminal vesicles on each image was analysed for displacement against time. Displacements between the 2.5 percentile and 97.5 percentile (i.e. the 2.5% trimmed range) for prostate and seminal vesicle centroid displacements were measured for 3, 5, 10 and 15 minutes time intervals in the anterior-posterior (AP), left-right (LR) and superior-inferior (SI) directions. Real time prostate and seminal vesicle displacement was compared for individual patients. The 2.5% trimmed range for 3, 5, 10 and 15 minutes for the seminal vesicle centroids in the SI direction measured 4.7 mm; 5.8 mm; 6.5 mm and 7.2 mm respectively. In the AP direction, it was 4.0 mm, 4.5 mm, 6.5 mm, and 7.0 mm. In the LR direction for 3, 5 and 10 minutes; for the left seminal vesicle, it was 2.7 mm, 2.8 mm, 3.4 mm and for the right seminal vesicle, it was 3.4 mm, 3.3 mm, and 3.4 mm. The correlation between the real-time prostate and seminal vesicle displacement varied substantially between patients indicating that the relationship between prostate displacement and seminal vesicles displacement is patient specific with the majority of the patients not having a strong relationship. Our study shows that seminal vesicle motion increases with treatment time, and that the prostate and seminal vesicle centroids do not move in unison in real time, and that an additional margin is required for independent seminal vesicle motion if treatment localisation is to the prostate

    Methodologies for the analysis of cadmium, copper, iron, lead, selenium and zinc in human seminal plasma and spermatozoa have been developed. Analyses were made directly in a dilution of seminal plasma or nitric acid digest of lyophilized cells using Zeeman-effect atomic absorption spectroscopy. Within-run coefficients of variation (CV's) for pooled specimens ranged from 0.5% to 9%. Between-run CV's ranged from 4% to 13%. Analysis of a seminal plasma specimen at 1/2, 1, 1 1/2, 3 1/2 and 5 hours post emission indicated that no change in seminal plasma trace element concentrations occurred on standing in contact with spermatozoa. Trace element concentrations were determined in specimens from patients undergoing infertility studies.

    Full Text Available The aim of this study was to determine the effect of sperm and seminal plasma (SP on the freezability of porcine semen. Semen of eight commercial males from two farms in the central-western region of Colombia (four boars in each farm was frozen and tested to select two males with high freezability (MHF and two with low freezability (MLF, according to the percentage of functionally competent sperm (FCS. Immediately after the collection was completed, the SP and sperm from the males selected were separated by centrifugation to combine the two types of plasma with the two types of sperm, incubate them for three hours and then freeze them. The variables evaluated were: sperm morphology, structural and functional integrity of plasmatic membrane, progressive and total motility, DNA fragmentation, acrosome integrity, capacitated sperm and FCS. The combination of sperm and plasma of MHF recorded the highest value (P<0.01 of acrosome integrity (24.3 ± 0.082 vs 6.076 ± 0.16 when compared to MLF plasma and cells. Membrane structural integrity was higher (P<0.01 with MHF (53.56 ± 0.0395 than with MLF plasma (47.49 ± 0.0419. The differences in porcine semen freezability depend on interactions between seminal plasma and sperm.

    The improvement over the last two decades in the treatment of cystic fibrosis led to an increase in life expectancy approaching 40 years at birth. Logically, the population of adult patients has been increasing and is currently 50% of patients followed in France. These therapeutic advances have justified the establishment in 2003 of a generalized neonatal screening for cystic fibrosis. The latest data of this screening show an incidence of CF of 1/5359 live births, far below the incidence of 1/2500 which was widely accepted twenty years ago. The performance of this screening is currently based on the dosage of trypsin immuno reactive, followed in case of exceeding the threshold of a search of the 30 most common mutations, can detect around 96% of 150 to 200 CF cases every year. Therefore, the possibility of a false negative of the screening cannot be excluded and evocative symptoms of cystic fibrosis, even for children born after 2003, will lead to prescribe a sweat test. While treatments available so far goal consequences of cystic fibrosis, a new therapeutic class to correct the functional defect of the mutated protein, called CFTR modulators, is emerging. Ivacaftor, leader of this new class, belonging to the category of "CFTR potentiator" got its access on the market in September 2012 for patients carrying the G551D mutation. New other molecules, named "CFTR correctors" which can have synergistic effect with ivacaftor and concern patients carrying the most common mutation--DF 508--are under development. Copyright © 2013.

    Full Text Available Background: Levels of serum gonadotropins have direct effects on testicular functions and spermatogenesis. Assessment of levels of serum gonadotropins from fathered subjects and infertile patients indicates wide range diversity. In this study, we tried to find out whether the levels of seminal FSH and LH affect the parameters of seminal fluid analysis (SFA and if there is any correlation between levels of serum FSH and LH in healthy men and infertile patients.Materials and Methods: Levels of FSH and LH in serum and seminal plasma were assessed randomly, in addition to examination of seminal fluid analysis from 12 normozoospermic subjects (age range: 33-56 years and 66 infertile patients (age range: 20-62 years with duration of infertility (15-201 months. Macroscopic and microscopic parameters of semen specimens were determined. Data were statistically analyzed using multiple correlation and regression, and MANOVA tests.Results: Result of the present study observed significant positive correlation between FSH levels in serum and seminal plasma (r=0.984; p<0.001 of normozoospermic subjects as compared to other groups of infertile patients. No correlations were noticed between LH levels in serum and seminal plasma of normozoospermic subjects and groups of infertile patients. Significant and positive correlation was assessed between sperm concentration and levels of seminal FSH (r=0.822; p<0.05 and r=0.940; p<0.01 and seminal LH (r=0.989; p<0.001 and r=0.999; p<0.001 of asthenozoospermic and OAT patients respectively. In asthenozoospermic patients, significant and positive correlations were observed between seminal FSH and percentages of sperm motility, progressive motility, sperm normal morphology and total progressive motile sperm/ejaculate.Conclusion: This study shows a strong association and effect between seminal FSH and serum FSH and parameters of SFA for normozoospermic men and different groups of infertile patients. These finding may call

  15. Seminal Quality Prediction Using Clustering-Based Decision Forests

    2014-08-01

    Full Text Available Prediction of seminal quality with statistical learning tools is an emerging methodology in decision support systems in biomedical engineering and is very useful in early diagnosis of seminal patients and selection of semen donors candidates. However, as is common in medical diagnosis, seminal quality prediction faces the class imbalance problem. In this paper, we propose a novel supervised ensemble learning approach, namely Clustering-Based Decision Forests, to tackle unbalanced class learning problem in seminal quality prediction. Experiment results on real fertility diagnosis dataset have shown that Clustering-Based Decision Forests outperforms decision tree, Support Vector Machines, random forests, multilayer perceptron neural networks and logistic regression by a noticeable margin. Clustering-Based Decision Forests can also be used to evaluate variables’ importance and the top five important factors that may affect semen concentration obtained in this study are age, serious trauma, sitting time, the season when the semen sample is produced, and high fevers in the last year. The findings could be helpful in explaining seminal concentration problems in infertile males or pre-screening semen donor candidates.

    In the study, the combination of protein fractionation by 1DE and HPLC-ESI-MS/MS was used to characterize the rainbow trout seminal plasma proteome. Our results led to the creation of a catalogue of rainbow trout seminal plasma proteins (152 proteins) and significantly contributed to the current knowledge regarding the protein composition of fish seminal plasma. The major proteins of rainbow trout seminal plasma, such as transferrin, apolipoproteins, complement C3, serum albumin, and hemopexin-, alpha-1-antiproteinase-, and precerebellin-like protein, were recognized as acute-phase proteins (proteins that plasma concentration changes in response to inflammation). This study provides the basis for further functional studies of fish seminal plasma proteins, as well as for the identification of novel biomarkers for sperm quality.

    Kershaw-Young, C M; Maxwell, W M C

    2012-08-01

    Camelid semen is characterized by a highly viscous, low-volume ejaculate with a low concentration of spermatozoa that exhibit low progressive motility. The viscous seminal plasma is currently the major impediment to the development of assisted reproductive technologies (ARTs) in camelids. To advance ARTs such as sperm cryopreservation and artificial insemination in camelids, it is necessary to identify the cause of the viscosity and gain an understanding of the role of seminal plasma components on sperm function and fertility. Numerous compounds and proteins have been identified as mediators of sperm function and predictors of fertility in other livestock species, and understanding the importance of specific proteins has progressed the success of ARTs in these species. Current knowledge on the components of camelid seminal plasma is outlined, together with the implications of these components for the development of ARTs in camelids. The cause of semen viscosity, as well as proteins that are present in camelid seminal plasma, is described for the first time. Seminal plasma components are compared with those of other species to hypothesize their role in sperm function and fertility. © 2012 Blackwell Verlag GmbH.

    Full Text Available Abstract The identification of the cystic fibrosis (CF gene opened the way for gene therapy. In the ten years since then, proof of principle in vitro and then in animal models in vivo has been followed by numerous clinical studies using both viral and non-viral vectors to transfer normal copies of the gene to the lungs and noses of CF patients. A wealth of data have emerged from these studies, reflecting enormous progress and also helping to focus and define key difficulties that remain unresolved. Gene therapy for CF remains the most promising possibility for curative rather than symptomatic therapy.

    2000-09-01

    In the present study, the concentrations of copper, iron, zinc, and malondialdehyde in human seminal plasma were measured and correlated with the sperm count and motility in human semen. Copper, iron, and zinc were analyzed by atomic absorption spectrometry, whereas malondialdehyde was measured by high-performance liquid chromatography. The malondialdehyde concentrations in asthenospermia and oligoasthenospermia were significantly higher than in normospermia. Copper and iron levels were higher in asthenospermia, whereas the zinc concentrations in both oligospermia and asthenospermia were lower than in normal controls. A negative correlation (r = -0.28, p iron, zinc, and malondialdehyde in seminal plasma. We concluded that changes in trace elements may be related to sperm quality and that lipid peroxidation, although it is not promoted in the seminal plasma by copper or iron or ameliorated by zinc, may be involved in the loss of sperm motility.

    PIXE has been applied to the multielemental and microanalysis of human spermatozoa. This is the first attempt to determine the chemical compositions of the motile spermatozoa free from contaminations of seminal plasma without loss of component elements during washing. The spermatozoa were isolated from semen by letting them swim into a kind of physiological saline, Tyrode's solution. Relative concentrations of P, K, Ca, Ti, Fe, Zn and Br in motile spermatozoa were determined by the use of the chlorine K X-ray peak intensity for evaluating the amount of Tyrode's solution contained in the sample targets. The concentrations of calcium and iron in spermatozoa were considerably higher than in seminal plasma. The concentrations of P, K, Zn and Br in spermatozoa were not so different from those in seminal plasma.

    To discuss the current status of treatment and the key points of nursing for seminal vesiculoscopy. The indication of seminal vesiculoscopy includes relapse or refractory hemospermia, ejaculatory duct stones and ejaculatory duct obstruction while acute infection of the genitourinary tract, hemorrhagic disease, and severe organ dysfunction are primary contraindications. Key points for perioperative care are as follows, we should focus on patients’ psychological disorders such as depression and anxiety, for example, intractable hemospermia may predispose patients to psychological problems. Postoperative routine care includes close observation for patients, infection prevention, and analgesia.

    Background: Abdominal lymphangioma is a rare benign congenital malformation of the mesenteric and/or retroperitoneal lymphatics. Clinical presentation is variable and may be misleading; therefore, complex imaging studies are necessary in the evaluation of this condition. US and CT have a major role in the correct preoperative diagnosis and provide important information regarding location, size, adjacent organ involvement, and expected complications. Objective: To evaluate the clinical and imaging findings of seven children with proven abdominal cystic lymphangioma. Materials and methods: Clinical and imaging files of seven children with pathologically proven abdominal lymphangioma, from three university hospitals, were retrospectively evaluated. Patient's ages ranged from 1 day to 6 years (mean, 2.2 years). Symptoms and signs included evidence of inflammation, abnormal prenatal US findings, chronic abdominal pain, haemorrhage following trauma, clinical signs of intestinal obstruction, and abdominal distension with lower extremities lymphoedema. Plain films of five patients, US of six patients and CT of five patients were reviewed. Sequential imaging examinations were available in two cases. Results: Abdominal plain films showed displacement of bowel loops by a soft tissue mass in five of six patients, two of them with dilatation of small bowel loops. US revealed an abdominal multiloculated septated cystic mass in five of six cases and a single pelvic cyst in one which changed in appearance over 2 months. Ascites was present in three cases. CT demonstrated a septated cystic mass of variable sizes in all available five cases. Sequential US and CT examinations in two patients showed progressive enlargement of the masses, increase of fluid echogenicity, and thickening of walls or septa in both cases, with multiplication of septa in one case. At surgery, mesenteric lymphangioma was found in five patients and retroperitoneal lymphangioma in the other two

    Cystic fibrosis (CF) is the most frequent metabolic disorder with autosomal recessive inheritance in the Caucasian population. The gene defect is located on the long arm of chromosome 7. In Germany today, the actual median survival is 37 years. The genetic defect caused by chloride anion disturbances affects multiple body systems but the morbidity and mortality is due to lung disease. The secretion of highly viscous mucus promotes viral and bacterial pulmonary infections leading to airway obstruction and consecutive destruction of the lung parenchyma. This article will review and discuss both the clinical aspects of the disease and the diagnostic methods, referring in particular to new imaging strategies. (orig.)

    Full Text Available Abstract Background Persistent dyspnea is a common finding in the cystic fibrosis patient that typically leads to further work up of an alternative pulmonary etiology. Adult cystic fibrosis patients; however, are growing in numbers and they are living into the ages in which coronary artery disease becomes prevalent. Coronary disease should be included in the consideration of diagnostic possibilities. Case presentation A 52-year-old white male with cystic fibrosis was evaluated for exertional dyspnea associated with vague chest discomfort. Diagnostic testing revealed normal white blood cell, hemoglobin and platelet count, basic metabolic panel, fasting lipid profile, HbA1c, with chest radiograph confirming chronic cystic findings unchanged from prior radiographs and an electrocardiogram that revealed sinus rhythm with left anterior fascicular block. Stress thallium testing demonstrated a reversible anteroseptal perfusion defect with a 55% left ventricular ejection fraction. Heart catheterization found a 99% occlusion of the left anterior descending artery extending into the two diagonal branches, with 100% obstruction of the left anterior descending artery at the trifurcation and 70% lesion affecting the first posterior lateral branch of the circumflex artery. Conclusion This case report represents the first description in the medical literature of a cystic fibrosis patient diagnosed with symptomatic coronary artery disease. Applying a standard clinical practice guide proved useful toward evaluating a differential diagnosis for a cystic fibrosis patient presenting with dyspnea and chest discomfort.

    There is increasing evidence that intestinal inflammation plays a major role in gastrointestinal symptoms in cystic fibrosis (CF). Fecal calprotectin is a marker that is elevated in several gastrointestinal inflammatory diseases, but little is known about its value in CF. We aimed to look for associations of elevated fecal calprotectin among CF patients and whether its level correlates with the clinical manifestations of CF. A single stool specimen was collected from 62 patients with CF. Fecal calprotectin was measured using the commercially available ELISA kits (PhiCal™ test). Clinical data were collected from patients' records and CF registry. There were no significant differences between CF patients with normal and abnormal fecal calprotectin levels. However, patients who were not receiving inhaled antibiotics had higher fecal calprotectin levels than those who were. Elevated fecal calprotectin may not accurately predict intestinal inflammation in CF. However, the fact that it was elevated in both pancreatic sufficient and insufficient groups supports the concept of "cystic fibrosis enteropathy" regardless of the pancreatic status.

    Full Text Available Water availability is a major limiting factor for crop production, making drought adaptation and its many component traits a desirable attribute of plant cultivars. Previous studies in cereal crops indicate that root traits expressed at early plant developmental stages, such as seminal root angle and root number, are associated with water extraction at different depths. Here, we conducted the first study to map seminal root traits in barley ( L.. Using a recently developed high-throughput phenotyping method, a panel of 30 barley genotypes and a doubled-haploid (DH population (ND24260 × ‘Flagship’ comprising 330 lines genotyped with diversity array technology (DArT markers were evaluated for seminal root angle (deviation from vertical and root number under controlled environmental conditions. A high degree of phenotypic variation was observed in the panel of 30 genotypes: 13.5 to 82.2 and 3.6 to 6.9° for root angle and root number, respectively. A similar range was observed in the DH population: 16.4 to 70.5 and 3.6 to 6.5° for root angle and number, respectively. Seven quantitative trait loci (QTL for seminal root traits (root angle, two QTL; root number, five QTL were detected in the DH population. A major QTL influencing both root angle and root number (/ was positioned on chromosome 5HL. Across-species analysis identified 10 common genes underlying root trait QTL in barley, wheat ( L., and sorghum [ (L. Moench]. Here, we provide insight into seminal root phenotypes and provide a first look at the genetics controlling these traits in barley.

    Cystic fibrosis has historically been considered a pulmonary disease, but with the increasing life expectancy of these patients, gastrointestinal manifestations are becoming more important. Furthermore, nutritional status is closely linked to pulmonary function and, thus, overall mortality. This article discusses gastrointestinal manifestations (which involve nutritional, pancreatic, hepatobiliary, and, in particular, gastrointestinal tract issues) of cystic fibrosis as well as management of the disease. In addition, the article discusses studies that have been critical to our understanding of gastrointestinal manifestations of cystic fibrosis. PMID:27330503

    Full Text Available Aim: To investigate various biochemical components of seminal plasma in Marwari stallions and Poitou Jacks and to find out their correlation with that of the seminal characteristics. Materials and Methods: In this study, semen was collected from six Marwari stallions and six Poitou jacks aged from 4 to 6 years and with known fertility status. The semen collection from the stallions were collected during the breeding season, i.e., between the months of April and June. From the collected semen ejaculates, we estimated the values of some biochemical components, viz., total protein content, total lipid content, and enzymes such as glutamic pyruvic transaminase (GPT, glutamic oxaloacetic transaminase (GOT, alkaline phosphatase (ALP, acid phosphatase (ACP, and lactate dehydrogenase (LDH as well as concentrations of glucose, cholesterol, total calcium (Ca, and phosphorus (P and correlations among different seminal parameters were statistically examined using the Pearson correlation coefficient. Results: In this study, we found positive correlations between semen volume as well as sperm concentration and GOT, GPT, ALP and ACP for both the group stallions. Significant correlation between motility and glucose, GOT and GPT could be an indication for their role metabolism and protection against free radicals to the spermatozoa. Conclusion: Based on the results, it is concluded that there is a positive correlation between some biochemical values such as glucose, Ca, ALP, and LDH and seminal parameters which play a key role in capacitation and onward movement of the spermatozoa.

    2015-01-01

    Full Text Available Spinal epidural arachnoid cyst (EAC is a rare, usually asymptomatic condition of unknown origin, which typically involves the lower thoracic spine. We report a case of posttraumatic symptomatic EAC with lumbar disc herniation. A 22-year-old man experienced back pain and sciatica after a traffic accident. Neurological examination revealed a right L5 radiculopathy. Magnetic resonance imaging demonstrated a cystic lesion at the L3 to L5 level and an L4-5 disc herniation; computed tomography myelography showed that the right L5 root was sandwiched between the cyst and the herniation. A dural defect was identified during surgery. The cyst was excised completely and the defect was repaired. A herniation was excised beside the dural sac. Histology showed that the cyst wall consisted of collagen and meningothelial cells. Postoperatively the symptoms resolved. Lumbar spinal EACs are rare; such cysts may arise from a congenital dural crack and grow gradually. The 6 cases of symptomatic lumbar EAC reported in the literature were not associated with disc herniation or trauma. In this case, the comorbid disc herniation was involved in symptom progression. Although many EACs are asymptomatic, comorbid spinal disorders such as disc herniation or trauma can result in symptom progression.

    This unit describes a recommended approach to identifying causal genetic variants in an individual suspected of having cystic fibrosis. An introduction to the genetics and clinical presentation of cystic fibrosis is initially presented, followed by a description of the two main strategies used in the molecular diagnosis of cystic fibrosis: (1) an initial targeted variant panel used to detect only the most common cystic fibrosis-causing variants in the CFTR gene, and (2) sequencing of the entire coding region of the CFTR gene to detect additional rare causal CFTR variants. Finally, the unit concludes with a discussion regarding the analytic and clinical validity of these approaches. Copyright © 2016 John Wiley & Sons, Inc.

    Full Text Available It was generally believed that Cystic fibrosis (CF is rare among Arabs; however, the few studies available from Egypt and other Arabic countries suggested the presence of many undiagnosed patients. The aim of the present study was to determine the frequency of CF patients out of the referred cases in a single referral hospital in Egypt. A total of 100 patients clinically suspected of having CF were recruited from the CF clinic of the Allergy and Pulmonology Unit, Children’s Hospital, Cairo University, Egypt, throughout a 2 year period. Sweat chloride testing was done for all patients using the Wescor macroduct system for collection of sweat. Quantitative analysis for chloride was then done by the thiocyanate colorimetric method. Patients positive for sweat chloride (⩾60 mmol/L were tested for the ΔF508 mutation using primer specific PCR for cystic fibrosis transmembrane conductance regulator (CFTR gene. Thirty-six patients (36% had a positive sweat chloride test. The main clinical presentations in patients were chronic cough in 32 (88.9%, failure to thrive in 27 (75%, steatorrhea in 24 (66.7%, and hepatobiliary involvement in 5 (13.9%. Positive consanguinity was reported in 50% of CF patients. Thirty-two patients were screened for ΔF508 mutation. Positive ΔF508 mutation was detected in 22 (68.8% patients, 8 (25% were homozygous, 14 (43.8% were heterozygous, and 10 (31.3% tested were negative. CF was diagnosed in more than third of patients suspected of having the disease on clinical grounds. This high frequency of CF among referred patients indicates that a high index of suspicion and an increasing availability of diagnostic tests lead to the identification of a higher number of affected individuals.

    Introduction Azoospermia affects more than 10% - 15% of infertile male subjects attending infertilty clinics. At present, testicular biopsy is the golden standard procedure for evaluating spermatogenesis status in men with azoospermia. Semen collection and analysis is a non-invasive method and has proven to be valuable in the evaluation of spermatogenesis. Identification of seminal plasma markers with testicular or extra-testicular origins have a great value in predicting the prescence of sperm in testicular tissue and presumptive cause of azoospermia. The aim of this study was to find such markers by comparing the content of seminal plasma using different methods in normospermic and azoospermic men. Materials and Methods Semen samples were collected from 200 men attending Avicenna Infertility Clinic (AIC) in Tehran, Iran. Semen samples were analysed according to WHO guidlines. The subjects were divided into two groups: normospermic (n = 100; group one) and azoospermic men (n = 100; group two) according to semen analysis results. Seminal plasma was separated by high speed centrifuagation and stored in -20° C. Four markers including fructose, neutral alpha glucosidase (NαG), inhibin B and anti-Müllerian hormone (AMH) were measured in seminal plasma. Fructose and NαG were evaluated by spectrophotometry, while inhibin B and AMH were assessed by ELISA method. The spermatogenesis status in the azoospermic group was evaluated by histopathological method following testicular biopsy. Results Fructose concentration showed no difference between the two groups. However, it was significantly correlated with sperm count (p < 0.01, r = -0.408). Seminal plasma inhibin B (OR: 1.01; 95%: CI: 1.005 - 1.016), AMH (OR: 1.63; 95% CI: 1.17 - 2.28) and NαG, (OR: 1.07; 95% CI: 1.04 - 1.1) levels were higher in normospermic subjects compared to azoospermic men. There were significant differences in inhibin B and AMH concentrations between the two groups based on the presence or

    The purpose of this study is to assess the MR findings of symptomatic osteochondromas. We evaluated 31 patients who between July, 1994 and May, 1997 underwent MR imaging for symptomatic osteochondroma. Fourteen were males and 17 were females, and their ages ranged from 8 to 49 (mean, 23) years. Using T1WI, T2WI and gadolinium-DTPA-enhanced T1WI, images were analysed according to signal intensity in the osseous component of the osteochondroma, thickness of the cartilage cap, and associated change in surrounding soft tissue. Clinical manifestation included a palpable mass or tendency to grow (n=22) and pain on movement (n=9). Complications were of three types : that which followed change in the osseous component of the tumor, associated change in surrounding soft tissue, and malignant transformation. In the osseous component, bone marrow edema or contusion was seen in 21 cases (67.7%), and in two (65%), fracture was observed. In surrounding soft tissue, muscle impingement was seen in 21 cases (67.7%), bursitis was in 7 cases (22.6 %), tenosynovitis in seven (22.6 %), and vascular compression in five (16.1 %). In three cases (9.7%), transformation to chondrosarcoma had occurred; two of these were derived from osteochondromatosis and one from a single osteochondroma. The thickness of the cartilage cap was as follow : 10 mm (n=3). In patients with symptomatic osteochondroma, MR imaging is useful for detecting both complications and malignant transformation.

    To describe the imaging features of unusual intracranial cystic meningiomas in infants and adults. We retrospectively reviewed the magnetic resonance and computed tomography findings for 2 female patients and 3 male patients, ranging in age from 1 to 73 years (median 41 years), with histopathologically proven cystic meningioma. Although cystic meningiomas usually appear as solid and cystic masses, they may present as a mainly multicystic lesion. The wall of a cystic part of the meningioma may include both enhancing and unenhancing areas at imaging. The cystic portion of a meningioma is hypointense on diffusion-weighted images and markedly hyperintense on corresponding apparent diffusion coefficient maps. (author)

    Queens of ants and bees normally obtain a lifetime supply of sperm on a single day of sexual activity, and sperm competition is expected to occur in lineages where queens receive sperm from multiple males. We compared singly mated (monandrous) and multiply mated (polyandrous) sister groups of ants...... and bees and show that seminal fluid of polyandrous species has a more positive effect on the survival of a male's own sperm than on other males' sperm. This difference was not observed in the monandrous species, suggesting that incapacitation of competing sperm may have independently evolved in both bees...... and ants. In Atta leafcutter ants, the negative effect of the seminal fluid of other males was negated by secretion from the queen sperm-storage organ, suggesting that queens may control ejaculate competition after sperm storage....

    Full Text Available Evidence suggests that each male may have a unique semen signature, and there are reasons to consider the possibility that semen sampling (i.e., being inseminated by different prospective mates during courtship may be part of an evolved female mate assessment strategy. Here we theorize that seminal plasma hypersensitivity represents the extreme negative end of this continuum and functions as a deterrent to mating with genetically incompatible suitors.

    Twenty-five years after the cystic fibrosis (CF) gene identification, this discovery actually begins to benefit to patients. Increasing our knowledge on CFTR biology, as well as technical progress made in order to screen for new drugs have made therapeutic strategies move an important step forward. It is likely that in the forthcoming years, the panel of molecules available for CF patients will be larger, with new activators and potentiators. The disease by itself may consequently change in its natural history. CF is an example of the so-called personalized medicine, aiming to fit treatment according to patient's genetic background. Ongoing clinical trials may enlarge the actually limited eligible number of CF patients for new drugs such as ivacaftor. Beyond this exciting and promising new therapeutic approach, one may not push symptomatic treatments on the side. Improvements have been made for inhaled antibiotics administration, aiming to simplify patient's life; clinical trials using new molecules able to liquefy mucus or with anti-inflammatory properties are actually underway. One important next step in the care for CF will be to design and conduct early intervention trials in CF infants. Newborn screening program have been widely implanted around the word, and cohorts studies have shown that both functional and structural abnormalities occurred very early, making the therapeutic window of opportunity tight.

    ABSTRACT Purpose Congenital and acquired pathologies of the seminal vesicles (SV) are rare diseases. The diagnosis of SV anomalies is frequently delayed or wrong due to the rarity of these diseases and the lack of adequate evaluation of SV pathology. For this reason, we aimed to comprehensively evaluate SV pathologies and accompanying genitourinary system abnormalities. Materials and Methods Between March 2012 and December 2015, 1455 male patients with different provisional diagnosis underwent MRI. Congenital and acquired pathology of the SV was identified in 42 of these patients. The patients were categorized according to their SV pathologies. The patients were analyzed in terms of genitourinary system findings associated with SV pathologies. Results SV pathologies were accompanied by other genitourinary system findings. Congenital SV pathologies were bilateral or predominantly in the left SV. Patients with bilateral SV hypoplasia were diagnosed at an earlier age compared to patients with unilateral SV agenesis. There was a significant association between abnormal signal intensity in the SV and benign prostate hypertrophy (BPH) and patient age. Conclusion SV pathologies are rare diseases of the genitourinary system. The association between seminal vesicle pathology and other genitourinary system diseases requires complete genitourinary system evaluation that includes the seminal vesicles. PMID:28853814

  12. Glycoprotein fucosylation is increased in seminal plasma of subfertile men

    Directory of Open Access Journals (Sweden)

    Beata Olejnik

    2015-04-01

    Full Text Available Fucose, the monosaccharide frequent in N- and O-glycans, is a part of Lewis-type antigens that are known to mediate direct sperm binding to the zona pellucida. Such interaction was found to be inhibited in vitroby fucose-containing oligo- and polysaccharides, as well as neoglycoproteins. The objective of this study was to screen seminal plasma proteins of infertile/subfertile men for the content and density of fucosylated glycoepitopes, and compare them to samples of fertile normozoospermic subjects. Seminal proteins were separated in polyacrylamide gel electrophoresis and blotted onto nitrocellulose membrane and probed with fucose-specific Aleuria aurantia lectin (AAL. Twelve electrophoretic bands were selected for quantitative densitometric analysis. It was found that the content, and especially the density of fucosylated glycans, were higher in glycoproteins present in seminal plasma of subfertile men. No profound differences in fucosylation density were found among the groups of normozoospermic, oligozoospermic, asthenozoospermic, and oligoasthenozoospermic subfertile men. According to the antibody probing, AAL-reactive bands can be attributed to male reproductive tract glycoproteins, including prostate-specific antigen, prostatic acid phosphatase, glycodelin and chorionic gonadotropin. Fibronectin, α1 -acid glycoprotein, α1 -antitrypsin, immunoglobulin G and antithrombin III may also contribute to this high fucosylation. It is suggested that the abundant fucosylated glycans in the sperm environment could interfere with the sperm surface and disturb the normal course of the fertilization cascade.

  13. Proteomics reveals novel Drosophila seminal fluid proteins transferred at mating.

    2008-07-01

    Full Text Available Across diverse taxa, seminal fluid proteins (Sfps transferred at mating affect the reproductive success of both sexes. Such reproductive proteins often evolve under positive selection between species; because of this rapid divergence, Sfps are hypothesized to play a role in speciation by contributing to reproductive isolation between populations. In Drosophila, individual Sfps have been characterized and are known to alter male sperm competitive ability and female post-mating behavior, but a proteomic-scale view of the transferred Sfps has been missing. Here we describe a novel proteomic method that uses whole-organism isotopic labeling to detect transferred Sfps in mated female D. melanogaster. We identified 63 proteins, which were previously unknown to function in reproduction, and confirmed the transfer of dozens of predicted Sfps. Relative quantification of protein abundance revealed that several of these novel Sfps are abundant in seminal fluid. Positive selection and tandem gene duplication are the prevailing forces of Sfp evolution, and comparative proteomics with additional species revealed lineage-specific changes in seminal fluid content. We also report a proteomic-based gene discovery method that uncovered 19 previously unannotated genes in D. melanogaster. Our results demonstrate an experimental method to identify transferred proteins in any system that is amenable to isotopic labeling, and they underscore the power of combining proteomic and evolutionary analyses to shed light on the complex process of Drosophila reproduction.

    To describe CT findings and differential points of cystic thymic lesions. We evaluated retrospectively total 19 masses with well marginated cystic lesions at thymic area on CT scans. They were 10 teratomas, 3 congenital thymic cysts, 2 multilocular thymic cysts(associated with thymoma and myasthenia gravis in each), 2 cysts Assciated with thymic Hodgkin's lymphomas an ectopic parathyroid cyst, and an infected thymic cyst. The radiological abnormalities evaluated were thickness of the wall, presence or abscene of septa, mural nodule, solid component, calcification and fat component. All three cases of congenital thymic cysts and an ectopic parathyroid cyst appeared as thin-walled unilocular cyst with homogeneous internal density and without identifiable solid component. In multilocular thymic cyst, there were thick wall and solid components(n =2), thick internal septa and calcifications(n = 1). The cysts of teratomas manifested thick walls(n = 9), internal septa(n = 4), calcifications(n = 6), fat components(n = 4), and solid components(n = 4). Cysts in Hodgkin's diseases appeared as multilocular or unilocular and had thick wall and septa without calcification. Infected thymic cyst presented with multilocular cystic mass with identifiable wall and septa, calcification, and solid components. The thymic diseases with cystic lesion include teratomas, congenital thymic cysts, multilocular thymic cysts, parathyroid cyst, and Hodgkin's disease. Congenital thymic cyst and ectopic parathyroid cyst are thin-walled unilocular cystic lesions. Cystic lesions associated with teratoma, Hodgkin's disease, and multilocular thymic cyst are thick-walled cystic lesions with or without solid component.

    We have recently shown seminal vesicle intraepithelial involvement of prostate cancer in cases with seminal vesicle invasion (pT3b). Based on the manner of seminal vesicle invasion, there could be 2 possible mechanisms of seminal vesicle intraepithelial involvement: direct intraepithelial invasion from prostate carcinoma in the muscular wall of seminal vesicles or intraepithelial involvement of cancer from the invaginated extraprostatic space (IES)/ejaculatory duct system to extraprostatic seminal vesicle. We aimed to clarify the manner and clinicopathological significance of seminal vesicle intraepithelial involvement. Of 1629 consecutive radical prostatectomies, 109 cases (6.7%) showed seminal vesicle invasion in whole-mounted radical prostatectomy specimens. In these pT3b cases, 18 (17%) showed seminal vesicle intraepithelial involvement by prostate cancer. Stromal invasion of the IES/ejaculatory duct system and ejaculatory duct intraepithelial invasion by prostate cancer were identified in 62 and 5 of 109 pT3b cases, respectively. However, the presence/absence of IES/ejaculatory duct system involvement by prostate cancer does not predict seminal vesicle intraepithelial involvement. No statistically significant correlation was observed between all pathologic parameters/biochemical recurrence and the presence/absence of seminal vesicle intra-epithelial involvement in the pT3b cases. These findings suggest that seminal vesicle intraepithelial involvement is more likely due to direct invasion of carcinoma from the muscular wall of seminal vesicles rather than intraepithelial extension from the ejaculatory duct system in the IES. Further studies with a substantially greater case number are needed to clarify the clinicopathological significance of seminal vesicle intraepithelial involvement in a better manner.

    Full Text Available Multiple sclerosis (MS is the commonest cause of disability in young adults. While there is increasing choice and better treatments available for delaying disease progression, there are still, very few, effective symptomatic treatments. For many patients such as those with primary progressive MS (PPMS and those that inevitably become secondary progressive, symptom management is the only treatment available. MS related symptoms are complex, interrelated, and can be interdependent. It requires good understanding of the condition, a holistic multidisciplinary approach, and above all, patient education and empowerment.

    Full Text Available Autoimmune pancreatitis (AIP can be chronic or recurrent, but frequently completely reversible after steroid treatment. A cystic lesion in AIP is a rare finding, and it can mimic a pancreatic cystic neoplasm. Difficulties in an exact diagnosis interfere with treatment, and surgery cannot be avoided in some cases. We report the history of a 63-year-old male presenting with jaundice and pruritus. AIP was confirmed by imaging and elevated IgG4 blood levels, and the patient completely recovered after corticosteroid therapy. One year later, he presented with a recurrent episode of AIP with elevated IgG4 levels, accompanied by the appearance of multiple intrapancreatic cystic lesions. All but 1 of these cysts disappeared after steroid treatment, but the remaining cyst in the pancreatic head was even somewhat larger 1 year later. Pancreatoduodenectomy was finally performed. Histology showed the wall of the cystic lesion to be fibrotic; the surrounding pancreatic tissue presented fibrosis, atrophy and lymphoplasmacytic infiltration by IgG4-positive cells, without malignant elements. Our case illustrates the rare possibility that cystic lesions can be part of AIP. These pseudocysts appear in the pancreatic segments involved in the autoimmune disease and can be a consequence of the local inflammation or related to ductal strictures. Steroid treatment should be initiated, after which these cysts can completely disappear with recovery from AIP. Surgical intervention may be necessary in some exceptional cases.

    Abstract Seminal plasma HIV-1 RNA level is an important determinant of the risk of HIV-1 sexual transmission. We investigated potential associations between seminal plasma cytokine levels and viral concentration in the seminal plasma of HIV-1-infected men. This was a prospective, observational study of paired blood and semen samples from 18 HIV-1 chronically infected men off antiretroviral therapy. HIV-1 RNA levels and cytokine levels in seminal plasma and blood plasma were measured and analyzed using simple linear regressions to screen for associations between cytokines and seminal plasma HIV-1 levels. Forward stepwise regression was performed to construct the final multivariate model. The median HIV-1 RNA concentrations were 4.42 log10 copies/ml (IQR 2.98, 4.70) and 2.96 log10 copies/ml (IQR 2, 4.18) in blood and seminal plasma, respectively. In stepwise multivariate linear regression analysis, blood HIV-1 RNA level (pplasma HIV-1 RNA level. After controlling for blood HIV-1 RNA level, seminal plasma HIV-1 RNA level was positively associated with interferon (IFN)-γ (p=0.03) and interleukin (IL)-17 (p=0.03) and negatively associated with IL-5 (p=0.0007) in seminal plasma. In addition to blood HIV-1 RNA level, cytokine profiles in the male genital tract are associated with HIV-1 RNA levels in semen. The Th1 and Th17 cytokines IFN-γ and IL-17 are associated with increased seminal plasma HIV-1 RNA, while the Th2 cytokine IL-5 is associated with decreased seminal plasma HIV-1 RNA. These results support the importance of genital tract immunomodulation in HIV-1 transmission. PMID:25209674

    Bronchiectasis is characterized by irreversible widening of the medium-sized airways, with inflammation, chronic bacterial infection and destruction of the bronchial walls. Exercise or inspiratory muscle training may improve quality of life and exercise endurance in people with non-cystic fibrosis bronchiectasis. Prolonged-use antibiotics improve clinical response rates, but may not reduce exacerbation rates or lung function. Surgery is often considered for people with extreme damage to one or two lobes of the lung who are at risk for severe infection or bleeding. In this review, the authors will focus on non-cystic fibrosis bronchiectasis, pointing out the differences in management when compared with the cystic fibrosis context, with special emphasis on surgical management.

    Males of many species fine-tune their ejaculates in response to sperm competition risk. Resource availability and the number of competitors during development can also strongly influence sperm production. However, despite the key role of seminal proteins in mediating reproductive processes, it is unclear whether seminal protein investment is dependent on the developmental environment.We manipulated the developmental environment of Drosophila melanogaster by rearing flies at low and high density. As expected, this resulted in large and small (i.e. high and low condition) adult phenotypes, respectively.As predicted, large males produced more of two key seminal proteins, sex peptide (SP) and ovulin, and were more successful at obtaining matings with both virgin and previously mated females. However, there was only a weak and non-significant trend for large males to transfer more absolute quantities of SP at mating, and thus, small males ejaculated proportionally more of their stored accessory gland SP resources.Males transferred more receptivity-inhibiting SP to large females. Despite this, large females remated more quickly than small females and thus responded to their developmental environment over and above the quantity of SP they received.The results are consistent with two non-mutually exclusive hypotheses. First, flies might respond to condition-dependent reproductive opportunities, with (i) small males investing heavily in ejaculates when mating opportunities arise and large males strategically partitioning SP resources and (ii) small females remating at reduced rates because they have higher mating costs or need to replenish sperm less often.Second, flies may be primed by their larval environment to deal with similar adult population densities, with (i) males perceiving high density as signalling increased competition, leading small males to invest proportionally more SP resources at mating and (ii) females perceiving high density as signalling abundant

    Quantitative high performance liquid chromatography (HPLC) to detect semen was investigated in this study. Briefly, 1cm of a gauze thread with a seminal stain was soaked in the reaction mixture (phenolphthalein diphosphate tetrasodium dissolved in acetate buffer) for 5-10 min, and the supernatant was analyzed by HPLC with a spectrophotometric detector. Phenolphthalein was liberated from the reagent in the presence of acid phosphatase, and the liberated phenolphthalein was detected objectively and was unaffected by blood contamination. Since liberation of phenolphthalein from the reagent occurred slightly in control negative samples, the cut-off value of the examination should be set at 1.0 microg/ml.

    Objective: To evaluate the clinical significance of corrected seminal prolactin assay in men with asthenospermia. Methods: Routine semen analysis and seminal plasma prolactin assay were performed on the men with asthenospermia, oligo-asthenospermia, normospermia. Prolactin was assessed by radioimmunoassay. The relationship between the level of corrected seminal plasma prolactin and the quality of semen was analyzed. Results: The mean level of the corrected seminal prolactin in the men with asthenospermia was (26.1±12.8) μg/L and was significantly higher than that of the men with normospermia. Seminal plasma prolactin concentration showed linear increasing alongside with the decreasing of the semen motility and motility degrees. Conclusion: The detection of corrected seminal plasma prolactin level will provide an objective index for evaluating the semen quality of asthenospermic men

    2018-01-01

    This paper conceptualises organisational diversity as constituted by psychoanalytic lack. Empirically, we show how diversity as Lacanian lack is understood as nothing in or of itself, but as an empty signifier with no signified. The lack of diversity becomes a catalyst for desiring particular ideas...... of diversity that, however, constantly change due to the empty form of diversity. Anxiety manifests itself in the obsession of unobtainable idealised forms of diversity as well as in the uncertainty associated with the traumatic experience of always falling short of what is desired in an object...... – the experience of failed diversity. Conclusively, we discuss the productive potential of the power of lack. The impossibility of diversity is what, at once, conditions the possibility of diversity. We therefore suggest that the symptomatic anxiety provoked by the lack should be enjoyed in order to engage...

    Patients with gallstones often present with multiple complaints. We wanted to study the major complaints of our patients undergoing laparoscopic cholecystectomy and the symptomatic relief afforded by the operation. We studied 113 patients with symptomatic gallstone disease who underwent laparoscopic cholecystectomy in a single surgical unit. Patients with proven common bile duct stones, obstructive jaundice, cholangitis, present or past associated abdominal pathology or cholecystoenteric fistula were excluded from the study. The mean follow up period was 18 months (range 10-22 months). A detailed account of the symptoms of gallstones, length of post-operative stay, persistence of symptoms, development of fresh symptoms and resumption of fat containing diet were assessed. The male to female ratio was 1:4. Common presenting symptoms were abdominal pain (96%), flatulence or feeling of fullness of abdomen (85%), heartburn (66%), belching (62%), sour eructation (52%), vomiting (48%) and nausea (45%). Mean postoperative hospital stay was 28 hours (range 9-68 hours). Biliary pain was relieved in 99% of patients after laparoscopic cholecystectomy (p cholecystectomy. Fresh symptoms that developed after laparoscopic cholecystectomy were heart-burn (6%), belching (3.5%), sour eructation (1%) and vomiting (0.5%). Post-cholecystectomy post-prandial diarrhoea occurred in 20% of the patients. The patients' appreciation of a satisfactory cosmetic result of operation scars was 100 percent. Fifteen female patients (13.5%) complained of increased weight gain of more than 5 kg after laparoscopic cholecystectomy [(p > 0.05; not significant (NS)]. Laparoscopic cholecystectomy significantly relieved symptoms of gall stone disease. Biliary pain, nausea, vomiting and sour eructations had better outcome compared to belching, flatulence and heartburn, which are also relieved in majority. Postcholecystectomy post-prandial diarrhea was a significant new symptom after cholecystectomy. Pre

    The incidental presence of seminal vesicle epithelium in prostate needle biopsies is generally recognisable through routine microscopy. However, the biopsy can sometimes be erroneously interpreted as malignant due to its architectural and cytological characteristics, and immunohistochemistry can be useful for correctly identifying the biopsy. Our objective was to analyse the potential usefulness of GATA-3 as a marker of seminal epithelium. Through immunohistochemistry with a monoclonal anti-GATA-3 antibody (clone L50-823), we studied seminal vesicle sections from 20 prostatectomy specimens, 12 prostate needle biopsies that contained seminal vesicle tissue and 68 prostate biopsies without seminal vesicle epithelium, 36 of which showed adenocarcinoma. Staining for GATA-3 was intense in the 20 seminal vesicles of the prostatectomy specimens and in the 12 prostate needle biopsies that contained seminal epithelium. In the 60 biopsies without a seminal vesicle, GATA-3 was positive in the prostate basal cells and even in the secretory cells (57 cases), although with less intensity in 55 of the cases. One of the 36 prostatic adenocarcinomas tested positive for GATA-3. The intense immunohistochemical expression of GATA-3 in the seminal vesicle epithelium can help identify the epithelium in prostate biopsies. This marker is also positive in the basal cells of healthy prostates and, with less intensity, in the secretory cells. Positivity, weak or moderate, is observed on rare occasions in prostatic adenocarcinomas. Copyright © 2017 AEU. Publicado por Elsevier España, S.L.U. All rights reserved.

    Full Text Available Introduction. CD59 is one of the complement regulatory proteins (CRPs which exert inhibitory function by blocking the formation of C5b-9 complex or Membrane Attacks complex (MAC. Regarding the therapeutic role of CD59 in treatment of pathological effects in uncontrolled activation of complements system and its efficiency to overcome the hyper-acute rejection, CD59 was suggested for maintenance of transplanted organ. In this study We determined and isolated CD59 from seminal plasma. Methods. Six normospermic sample according to WHO standards were chosen. Plasma of samples was separated and to remove the postasomes, the seminal plama was ultra centrifuged. CD59 was detected by Dot-Blot using CD59 mAb (MEM43. The molecular weight and purity of protein was detected by SOS-PAGE method follwed by Westerm Blot. Results. Protein was present in the 6.5 ml and 15ml of gel fitration fractions. Molecular weight based on marker size in these two fractions was 65 and 21KD respectively. Discussion. CD59 had previously beem purified by lysis of erythrocyte cell membrane. Because of use of detergent and preservative agents, this method decreased physiologic effects of the protein. In this study the isolation was performed from prostasome granules" without using of any detergent and preservative agents.

    Full Text Available Cystic fibrosis (CF is the most frequent lethal autosomal recessive disorder among Caucasians (incidence: 1:2,500 newborn. In the last two decades CF prognosis considerably improved and many patients well survive into their adulthood. Furthermore, milder CF with a late onset was described. CF is a challenge for laboratory of molecular genetics that greatly contributes to the natural history of the disease since fetal age. Carrier screening and prenatal diagnosis, also by non-invasive analysis of maternal blood fetal DNA, are now available, and many labs offer preimplantation diagnosis. The major criticism in prenatal medicine is the lack of an effective multidisciplinary counseling that helps the couples to plan their reasoned reproductive choice. Most countries offer newborn screening that significantly reduce CF morbidity but different protocols based on blood trypsin, molecular analysis and sweat chloride cause a variable efficiency of the screening programs. Again, laboratory is crucial for CF diagnosis in symptomatic patients: sweat chloride is the diagnostic golden standard, but different methodologies and the lack of quality control in most labs reduce its effectiveness. Molecular analysis contributes to confirm diagnosis in symptomatic subjects; furthermore, it helps to predict the disease outcome on the basis of the mutation (genotype-phenotype correlation and mutations in a myriad of genes, inherited independently by CF transmembrane conductance regulator (CFTR, which may modulate the clinical expression of the disease in each single patient (modifier genes. More recently, the search of the CFTR mutations gained a role in selecting CF patients that may benefit from biological therapy based on correctors and potentiators that are effective in patients bearing specific mutations (personalized therapy. All such applications of molecular diagnostics confirm the “uniqueness” of each CF patient, offering to laboratory medicine the

    Full Text Available The cystic swellings of scrotum are one among the commonest clinical entities faced by a surgeon in day to day practice and a cause of concern to the patient more with his fertility. Presenting with varied etiology they can represent a wide range of medical issues. Gold standard for the management of such cystic swellings of scrotum continues to be surgical extirpation of the lesion. Objective: To identify the cause, mode of presentation, various modalities of treatment and outcome of these with their complications. Method: A total of 170 cases of cystic swellings of scrotum fulfilling the methodology criteria were subjected to the preformatted study. Diagnosis was mostly by clinical examination and supported by ultrasonography. All cases were treated surgically with the appropriate surgical procedure. Results: Maximum patients were in the age group of 31-50 years and presented with scrotal swelling (59% and more commonly affecting the right side. The commonest cause for cystic swelling of the scrotum was primary vaginal hydrocele (55%. Surgical procedure using Lords Plication was found to be simple, effective and associated with minimum post operative complications; the other conventional techniques like Partial/sub-total excision of sac, everson of sac were associated with more complications like haematoma, scrotal edema and infection. Majority of patients were discharged on 7th Post-operative day. Conclusion: The present study, primary vaginal hydrocele was the commonest cystic swelling of scrotum and treated surgically showed good results. Lord’s procedure was associated with the less post-operative complications, minimal tissue handling and good haemostatic control.

    We analysed the effect of irradiation of an enlarged spleen in some hematologic diseases: chronic myelaemia, osteomyelophybrosis and chronic lymphadenosis, where splenectomy had been contraindicated and where pain has been a leading symptom and also the discomfort because of an enlarged spleen. For 20 years in the Clinic of Radiotherapy have been treated 23 patients with the above mentioned diseases. We have irradiated all patients using X-ray and later- Co-60. To reach a palliative effect we have irradiated patients with single doses from 50 cGy to 100 cGy with an interval of 2-3 days between each fraction, but the total doses have been different- from 400 cGy to 1500 cGy. The enlarged spleen has reached the pelvis in 3 cm to 17 cm below the costal margin, and in some patients has crossed the median line of the body going in some centimetres on the other side. The reduction of splenic size and volume is as follows: full reduction in 6 patients (26.1%) and partial in 17 (73.9%). All patients resulted in decreases in pain and tension in abdomen and the total discomfort. No serious side haematologic effects were encountered. Our experience indicates that cautious splenic irradiation can be a safe and useful therapeutic alternative. The symptomatic palliation in patients, where splenectomy is not an option, is effective and is an additional alternative for an improvement of their general condition

  7. Role of ATP binding and hydrolysis in the gating of the cystic fibrosis transmembrane conductance regulator

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available The CFTR gene is unique within the ATP-binding cassette (ABC protein family, predominantly of transporters, by coding a chloride channel. The gating mechanism of ABC proteins has been characterized by the ATP Switch model in terms cycles of dimer formation and dissociation linked to ATP binding and hydrolysis, respectively. It would be of interest to assess the extent that Cystic Fibrosis Transmembrane Conductance Regulator (CFTR, a functional channel, fits the ATP Switch model for ABC transporters. Additional transporter mechanisms, namely those of Pgp and HlyB, are discussed for perspective. Literature search of databases selected key references in comparing and contrasting the gating mechanism. CFTR is a functional chloride channel facilitating transmembrane anion flow down electrochemical gradients. A dysfunctional CFTR protein results in cystic fibrosis, a fatal pleiotropic disease currently managed symptomatically. Understanding the gating mechanism will help target drug development aimed at alleviating and curing the disease.

    To analyze the relationship between seminal vesicle cysts (SVC) and the presence of congenital malformations of the genitourinary tract. The authors analyzed retrospectively the abdominal images of eight patients who fulfilled the ultrasound criteria for a definitive diagnosis of SVC: the patients had been studied over a seven-year period. The diagnostic assessment was supported by magnetic resonance in 5 cases, computed tomography in 3, intravenous urography in 1 and vesiculo-deferentography in 2. SVC were associated with congenital malformations of the genitourinary tract in six cases (75%): autosomal dominant polycystic kidney disease in 3, renal agenesis-hypoplasia in 2 and stenosis of the pyeloureteral junction in 1. The cysts were bilateral in six cases. In the remaining two cases in which the cysts were unilateral, renal agenesis-hypoplasia was also present and the cysts were ipsilateral to the renal malformation. In one case, hypoplasia was accompanied by ectopic ureter inserted into the affected seminal vesicle. In two cases, the presence of SVC was the only abnormal finding. One of these two patients had a history of genitourinary tuberculosis and the other had no medical history of interest. When SVC are detected, it is necessary to examine the entire urinary tract of the patient given the frequency with which they are associated with congenital malformations of the renal and excretory systems. In those cases in which there is no accompanying anomaly, the patient should be studied to detect a possible infectious episode to which an obstructive etiology could be attributed. (Author) 17 refs

    Full Text Available La función reproductiva masculina se ha visto deteriorada significativamente en los últimos 50 años y dicha alteración podría estar relacionada con la exposición a diferentes tóxicos y contaminantes ocupacionales y ambientales. El objetivo de este trabajo es resumir el impacto de la exposición humana a metales pesados y plaguicidas sobre la función reproductiva masculina. La mayoría de los plaguicidas y metales pesados se consideran tóxicos reproductivos y podrían afectar negativamente al sistema reproductivo masculino debido al efecto alterador sobre el eje hipotálamo-pituitario-gonadal, o directamente afectando a la espermatogénesis, dando lugar a una alteración de la calidad seminal. Los efectos negativos de estos compuestos se han relacionado con los principales parámetros espermáticos (concentración, morfología y movilidad normal, volumen seminal y recuento total espermático, alteración del ADN espermático, así como con cambios en los niveles de hormonas reproductivas. El uso de algunas de estas sustancias ya está prohibido mientras que se continúa comercializando con otras. Sería recomendable una legislación más severa que impida cualquier exposición a este tipo de tóxicos debido a su confirmado efecto perjudicial sobre la salud reproductiva masculina.

    Cystic fibrosis (CF) is a multi-systemic disease with major impact on the lungs. Pulmonary manifestation is crucial for the prognosis and life expectancy of patients. Imaging modalities and lung function tests reflect the pulmonary status in these patients. The standard imaging modality for diagnosis and follow-up of pulmonary changes is chest x-ray. The gold standard for the detection of parenchymal lung changes remains high resolution computed tomography (HRCT), but this is not used routinely for CF-patients due to radiation exposure. Magnetic resonance imaging (MRI) used to be of no importance in monitoring cystic fibrosis lung disease, as shown in studies from the 1980s and early 1990s. The continuing improvement of MRI techniques, however, has allowed for an adequate application of this non-radiation method in diagnosing the major pulmonary findings in CF, in addition to the assessment of lung function.

    Full Text Available A 14-year-old was girl admitted to our hospital with a subcutaneous mass of the occipital head. The mass had grown for 6 years, after she had sustained a head injury at the age of 6, and was located directly under a previous wound. Skull X-ray Photograph (xp, computed tomography (CT, and magnetic resonance imaging (MRI showed a bony defect and cystic changes in the skull corresponding to a subcutaneous mass. Bone scintigraphy revealed partial accumulation. The patient underwent total removal of the skull mass, and the diagnosis from the pathological findings of the cyst wall was fibrous dysplasia (FD. The radiographic findings for cystic cranial FD can be various. Progressive skull disease has been reported to be associated with head trauma, but the relationship between cranial FD and head trauma has not been previously reported. Previous studies have suggested that c-fos gene expression is a key mechanism in injury-induced FD.

    Autosomal dominant polycystic kidney disease (ADPKD) is a systemic hereditary disorder characterized by bilateral diffuse renal cysts. Extrarenal involvement is a well known manifestation of ADPKD. Cysts in the liver, pancreas, lung, spleen, oesophagus, ovary, testis, epididymis, prostate, thyroid, bladder, uterus, brain, paraespinal, and seminal vesicle have also been described. The occurrence of seminal vesicle cysts is often unrecognised. We report here a man with seminal vesicle cysts and azoospermia associated with ADPKD. Seminal vesicle cysts are not uncommon in ADPKD and in some cases it is associated with infertility. Ultrasound and computed tomography imaging were effective in documenting the underlying lesions non-invasively. Studies evaluating fertility in patients with seminal vesicle cysts and ADPKD are needed.

  18. Male mating rate is constrained by seminal fluid availability in bedbugs, Cimex lectularius.

    Directory of Open Access Journals (Sweden)

    Klaus Reinhardt

    Full Text Available Sexual selection, differences in reproductive success between individuals, continues beyond acquiring a mating partner and affects ejaculate size and composition (sperm competition. Sperm and seminal fluid have very different roles in sperm competition but both components encompass production costs for the male. Theoretical models predict that males should spend ejaculate components prudently and differently for sperm and seminal fluid but empirical evidence for independent variation of sperm number and seminal fluid volume is scarce. It is also largely unknown how sperm and seminal fluid variation affect future mating rate. In bedbugs we developed a protocol to examine the role of seminal fluids in ejaculate allocation and its effect on future male mating rate. Using age-related changes in sperm and seminal fluid volume we estimated the lowest capacity at which mating activity started. We then showed that sexually active males allocate 12% of their sperm and 19% of their seminal fluid volume per mating and predicted that males would be depleted of seminal fluid but not of sperm. We tested (and confirmed this prediction empirically. Finally, the slightly faster replenishment of seminal fluid compared to sperm did not outweigh the faster decrease during mating. Our results suggest that male mating rate can be constrained by the availability of seminal fluids. Our protocol might be applicable to a range of other organisms. We discuss the idea that economic considerations in sexual conflict research might benefit from distinguishing between costs and benefits that are ejaculate dose-dependent and those that are frequency-dependent on the mating rate per se.

    The objective of this paper is to apply the transurethral endoscopic technique with the ureteroscope for diagnosis and treatment of the seminal vesicle and ejaculatory duct disorders. At present there is no special equipment designed to enter directly into the seminal vesicle cavity under direct vision. Sixty patients with disorders of the seminal vesicle were included in this study. A 6.5 F rigid ureteroscope (Richard Wolf GmbH, Knittlingen, Germany) was inserted into the posterior urethra to find the verumontanum. Then a 3F catheter (Shanghai Kangge JJMC, Shanghai, China) was inserted into the verumontanum. After that the 6.5 F ureteroscope was introduced into the ejaculatory duct and seminal vesicle to examine them under direct observation. A total of 55 patients were diagnosed and cured successfully with the ureteroscope; 42 (76.4%) patients were discovered to have hemospermia. They were given an anti-inflammatory and seminal vesicle washing. Eight (14.5%) patients who had small stones in the seminal vesicle were offered the operation of the stones removal. Five (9.1%) patients were found to have seminal vesicle gland cysts. The orifices of ejaculatory duct were not found in 3 patients among 5 who were operated unsuccessfully. The ureteroscope failed to enter the seminal vesicle in 2 patients. Some diseases of the seminal vesicle and ejaculatory duct can be easily diagnosed and treated in the clinical practice using a ureteroscope. Transurethral endoscopy technique with the ureteroscope for diagnosis and therapy of the seminal vesicle and ejaculatory duct disorders is safe and practicable.

    Full Text Available Abstract Background Camelids are induced (reflex ovulators. We have recently documented the presence of an ovulation-inducing factor (OIF in the seminal plasma of alpacas and llamas. The objective was to test the hypothesis that OIF exerts its effect via a systemic rather than a local route and that endometrial curettage will enhance the ovulatory response to intrauterine deposition of seminal plasma in alpacas. Methods Female alpacas were assigned randomly to 6 groups (n = 15 to 17 per group in a 2 × 3 factorial design to test the effect of seminal plasma versus phosphate-buffered saline (PBS given by intramuscular injection, by intrauterine infusion, or by intrauterine infusion after endometrial curettage. Specifically, alpacas in the respective groups were given 1 2 ml of alpaca seminal plasma intramuscularly, 2 2 ml of PBS intramuscularly (negative control group, 3 2 ml of alpaca seminal plasma by intrauterine infusion, 4 2 ml of PBS by intrauterine infusion (negative control group, 5 2 ml of alpaca seminal plasma by intrauterine infusion after endometrial curettage, or 6 2 ml of PBS by intrauterine infusion after endometrial curettage (negative control group. The alpacas were examined by transrectal ultrasonography to detect ovulation and measure follicular and luteal diameters. Results Intramuscular administration of seminal plasma resulted in a higher ovulation rate than intrauterine administration of seminal plasma (93% versus 41%; P Conclusion We conclude that 1 OIF in seminal plasma effects ovulation via a systemic rather than a local route, 2 disruption of the endometrial mucosa by curettage facilitated the absorption of OIF and increased the ovulatory effect of seminal plasma, and 3 ovulation in alpacas is not associated with a physical stimulation of the genital tract, and 4 the alpaca represents an excellent biological model to evaluate the bioactivity of OIF.

    The sinonasal involvement is one of the most common manifestations in cystic fibrosis. Data show a high incidence of chronic rhino sinusitis in these patients. Although it has been found radiographic opacification of the sinus in more than 90% of cases, few are symptomatic. So that, it is difficult to recognize nasossinusal disease in patients with cystic fibrosis. Questionnaire, nasal endoscopy and CT-scan are very important methods in this approach. Aim: to evaluate the diagnosis of chronic rhino sinusitis in patients with cystic fibrosis by anamnesis, nasal endoscopy and CT-scan and compare those results.Study Design: Clinical prospective. Material and method: evaluation of 34 patients - older than 6 years and with a confirmed diagnoses of cystic fibrosis - by anamnesis (questionnaire), nasal endoscopy (score Lund-Kennedy) and CT-scan (score Lund-Mackay). Results: chronic rhino sinusitis was confirmed in: 20,58% of cases by the questionnaire, 73,52% of the cases by the nasal endoscopy and in 93,54% of the cases by the CT-scan. The results showed significant differences. The correlation between nasal endoscopy score (Lund-Kennedy score) and CT-scan score (Lund-Mackay score) was statistically significant. Conclusion: the diagnosis of chronic rhino sinusitis was statistically different between the three methods. It was higher in imaging analysis and lower in questionnaire. The nasal endoscopy is an excellent method to evaluate nasossinusal disease in cystic fibrosis. (author)

    Nasal polyps frequently occur in people with cystic fibrosis. Sinus infections have been shown to be a factor in the development of serious chest complications in these people. Nasal polyps have been linked to a higher risk of lower respiratory tract infections with Pseudomonas aeruginosa . Topical nasal steroids are of proven efficacy for treating nasal polyposis in the non-cystic fibrosis population. There is no clear current evidence for the efficacy of topical steroids for nasal polyps in people with cystic fibrosis. This is an updated version of a previously published review. To assess the effectiveness of topical nasal steroids for treating symptomatic nasal polyps in people with cystic fibrosis. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register comprising references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Latest search: 10 June 2015. Randomised and quasi-randomised controlled comparing the effects of topical nasal steroids to placebo in people with nasal polyps with cystic fibrosis. Two authors independently assessed risk of bias in the included trial and extracted data. One single-centred trial (46 participants) was identified comparing a topical steroid (betamethasone) given as nasal drops to placebo. Treatment was given twice daily for six weeks; 22 participants received the active drug.Subjective symptom scores, change in polyp size, and side effects were assessed. There was no difference in nasal symptom scores between the treatment and placebo groups. Betamethasone was effective in reducing the size of polyps, but was associated with increased reports of mild side effects, nasal bleeding and discomfort.Risk of bias was high since over 50% of people enrolled did not complete the study. Follow-up of participants was short (six weeks) also reducing the significance of the results for clinical practice. This review

    Adenoid cystic carcinoma (ACC) is a rare cancer, and there are no standard-of-care treatments for patients with metastatic ACC. We herein report a patient with lung metastasis of ACC who achieved a favorable response to levetiracetam. A 52-year-old Japanese man was admitted to our hospital because of multiple lung metastases of ACC. We performed first-line chemotherapy with cisplatin plus gemcitabine, and subsequently oral S-1 as second-line chemotherapy, which resulted in disease progression. The patient developed symptomatic epilepsy and received levetiracetam (250 mg twice daily). At five months after the initiation of levetiracetam, chest computed tomography showed regression of the metastatic lung lesions.

    2015-05-01

    Individuals with cystic fibrosis (CF) suffer progressive airway inflammation, infection and lung damage. Airway inflammation and infection are present from early in life, often before children are symptomatic. CF gene mutations cause changes in the CF transmembrane regulator protein that result in an aberrant airway microenvironment including airway surface liquid (ASL) dehydration, reduced ASL acidity, altered airway mucin and a dysregulated inflammatory response. This review discusses how an altered microenvironment drives CF lung disease before overt airway infection, the response of the CF airway to early infection, and methods to prevent inflammation and early lung disease. © 2015 Asian Pacific Society of Respirology.

    Profound pulpal anesthesia after a successful inferior alveolar nerve block can be difficult to achieve when the clinical condition is a pulpal diagnosis of symptomatic irreversible pulpitis. The authors reviewed the literature as it relates to the anesthesia necessary for endodontic therapy of patients with painful, vital, mandibular teeth diagnosed with symptomatic irreversible pulpitis. Supplemental anesthetic techniques and medications are available that can be used to improve pulpal anesthesia for patients with the clinical condition of symptomatic irreversible pulpitis. The authors identified treatment recommendations for anesthesia in the case of symptomatic irreversible pulpitis based on a review of the available evidence.

    Pericardial cysts are most commonly located at the cardiophrenic angle or, rarely, in the posterior or anterior superior mediastinum. The majority of pericardial cysts are asymptomatic and are found incidentally. Symptomatic pericardial cysts present with dyspnoea, chest pain, or persistent cough. We describe four patients with symptomatic pericardial cysts who were treated with either echocardiographically guided percutaneous aspiration or video-assisted thoracoscopic surgery, or both; thoracotomy; or conservative therapy.

    Human seminal plasma is a natural reservoir of antioxidants that protect spermatozoa from oxidative damages. There is evidence in literature supports the fact that impairments in seminal antioxidant and lipid per-oxidation status play important roles in the physiopathology of male infertility. Our present study forms the first one which was carried out in Tunisia. We evaluated the antioxidant status in the seminal plasma of 120 infertile men programmed to In Vitro Fertilization (IVF) for the first tentative. Patients were characterized by an idiopathic infertility. They were divided into three groups: normozoospermics who were considered as controls (n=40), asthenozoospermics (Astheno; n=45) and oligoasthenoteratozoospermics (OAT; n=35). Seminal activities of superoxide dismutase (SOD) and glutathione peroxidase (GPX) and the levels of glutathione (GSH), zinc (Zn) and malondialdehyde (MDA) were measured. With the significant increase of the seminal activities of SOD and GPX in normozoospermics group, there were positive correlations observed between this enzymes and sperm quality. Also, significant elevated rates of seminal zinc and GSH were observed in control group, but there was contradictory associations reflecting the effects of these antioxidants on semen parameters. However, we noted significant increase of MDA levels in groups with abnormal seminogram. We showed negative associations between this per-oxidative marker and sperm parameters. These results obviously suggested that impairment on seminal antioxidants is an important risk factor for low sperm quality associated to idiopathic infertility and as a result can lead to poor IVF outcome.

    In a region of humid tropical forest, ten boars of from 12 to 24 months of age were selected to evaluate the effect of climatic variables measured on the day of semen collection and for each of preceding 45 days. On seminal characteristics, the variability of each characteristic was separated into an intra individual component and an interindividual component, using maximum likelihood estimators (PROC VARCOMP of SAS). In order to relate the seminal characteristics with the climatic variables, morphological abnormalities were grouped according to the affected spermatic region, into head. Midsection and main section abnormalities; the other characteristics were evaluated without any modification. Possible correlations between seminal characteristics and climatic variables were evaluated. In a total of 298 ejaculates collected weekly during a period of 30 weeks, except for total volume and morphological abnormalities. The seminal characteristics presented low or moderate intra and interindividual variation and were similar to those found in other latitudes, with a tendency to present greater seminal volumes and concentrations maximum temperature minimum temperature. Range among temperatures. Relative humidity and precipitation of the day of the semen collection and on each of the preceding 45 days had low effects on the seminal characteristics. It is possible that the boars in warm humid tropical areas develop a high level of adaptation that permits an adequate testicular thermoregulation that favors the spermatogenic function of the seminiferous tubules in a way that does not perceptibly affect production the seminal quality

    It is generally accepted that dopamine agonists (DA) represent the first-line treatment for most patients with prolactinoma, and patients become candidates for surgical intervention when DA is contraindicated. Surgical indication for cystic prolactinoma remains controversial. This study was performed to investigate the significance of surgery for cystic prolactinoma. A total of 28 patients that underwent transsphenoidal resection of prolactinoma between February 2004 and May 2016 were reviewed. Five consecutive patients with cystic prolactinoma were included in this study. Our surgical strategy for cystic prolactinoma was categorized as follows: first, when the purpose of surgical resection was normalization of the prolactin level, aggressive resection was performed; second, when volume reduction was essential to relieve the visual symptoms and headache, internal decompression was performed followed by DA therapy. The clinical outcomes were analyzed accordingly. All cystic prolactinoma were resected via the transsphenoidal approach without any complications, and all symptoms including visual impairment and hypogonadal activity were finally relieved combined with medication. Surgery for cystic prolactinoma could be a better option. Transsphenoidal surgery is relatively safe to remove the cystic prolactinoma, additionally it can normalize the prolactine level and achieve adequate and rapid decompression of optic chiasm. The risk of transsphenoidal surgery is highly dependent on the skill of the surgeon and treatment decision for cystic prolactinoma needs to be individualized for each patient.

    Full Text Available Seminal vesicle tumors are very rare malignancies which are not diagnosed in daily clinical oncology practice. Primary malignant tumors in seminal vesicle are difficult to define due to the lack of specific symptoms in the early stages of the disease. Another obstacle of proper diagnosis is the frequent invasion of tumors of the surrounding organs, especially the prostate, rectum and bladder which is difficult to differentiate. Very often seminal vesicle tumors are difficult to detect. Digital rectal examination as well as transrectal ultrasound scan (US could reveal a bulky mass in the retrovesical space. Computed tomography and magnetic resonance imaging (MRI are the main diagnostic methods which could help to reveal pathologic masses in the region of seminal vesicles. Levels of prostate-specific antigen, carcinoembryonic antigen and tumor markers specific for colorectal cancer are negative in seminal vesicle tumors.The world experience of treating seminal vesicle tumors is very limited. There is paucity of data regarding appropriate choice of surgical approach and further treatment strategy and most of the time the treatment is individualized and based on very scarce information. At the same time surgical approach may vary significantly from vesiculectomy to pelvic exenteration. Possibility of using any regimens of adjuvant radiation therapy, chemotherapy or hormone therapy is highly debatable. However, aggressive surgical approach with radical tumor removal followed by extended lymphodissection shows the most favorable results in survival of patients suffering from seminal vesicle cancer.Squamous cell carcinoma of the seminal vesicles is presumed to be an extremely rare disease as there are only 3 reports of it in the world literature. We report a case of patient B. suffering from squamous cell carcinoma of the right seminal vesicle whom we conducted an aggressive surgical approach – prostatovesiculectomy followed by resection of the

  19. Seminal plasma aids the survival and cervical transit of epididymal ram spermatozoa.

    Seminal plasma purportedly plays a critical role in reproduction, but epididymal spermatozoa are capable of fertilisation following deposition in the uterus, calling into question the biological requirement of this substance. Through a combination of direct observation of spermatozoa in utero using probe-based Confocal Laser Endomicroscopy, in vivo assessment of sperm fertility and in vitro analysis of various sperm functional parameters, this study investigated the role of seminal plasma in spermatozoa transit through the cervix of the ewe. Following deposition in the cervical os, epididymal spermatozoa previously exposed to seminal plasma displayed an enhanced ability to traverse the cervix as evidenced by both significantly higher pregnancy rates and numbers of spermatozoa observed at the utero-tubal junction when compared with epididymal spermatozoa not previously exposed to seminal plasma. The beneficial effect of seminal plasma on sperm transport was clearly localised to transit through the cervix as pregnancy rates of spermatozoa deposited directly into the uterus were unaffected by exposure to seminal plasma. This phenomenon was not explained by changes to sperm motion characteristics, as seminal plasma had no effect on the motility, kinematic parameters or mitochondrial membrane potential of spermatozoa. Rather, in vitro testing revealed that seminal plasma improved the ability of epididymal spermatozoa to penetrate cervical mucus recovered from ewes in oestrus. These results demonstrate that the survival and transport of ram spermatozoa through the cervix of the ewe is not linked to their motility or velocity but rather the presence of some cervical penetration trait conferred by exposure to seminal plasma. © 2014 Society for Reproduction and Fertility.

Ultrasonography showed absence of the right kidney, a bladder tumour and a round retrovesical hypoechogenic mass with posterior acoustic enhancement. It showed low attenuation on CT, low signal intensity on T1-weighted MR images and high signal intensity on T2-weighted MR images. Intravenous urography (IVU) and cystoscopy were also performed. After surgery, it proved to be a seminal vesicle cyst. The embryology, imaging characteristics and differential diagnosis of seminal vesicle cysts are discussed.

    #  1. Many internally-fertilizing animals produce seminal fluid which is transferred along with sperm during mating. Seminal fluid typically contains a diverse range of chemicals that coordinate sperm storage, moderate sperm motility, provide advantages in sexual selection and influence female...... a different male. This study therefore provides strong evidence that seminal fluid does not kill rival sperm, and instead can actually protect them. This study also tested whether chemicals in the female reproductive tract harm sperm as in another Drosophila species, but found no evidence of this. # 3...

    The life expectancy of patients with cystic fibrosis (CF) has steadily increased over recent decades with a corresponding increase in the frequency of complications of the disease. Radiologists are increasingly involved with managing and identifying the pulmonary complications of CF. This article reviews the common manifestations of CF lung disease as well as updating radiologists with a number of less well-known complications of the condition. Early and accurate detection of the pulmonary effects of CF are increasingly important to prevent irreversible lung damage and give patients the greatest possibility of benefiting from the new therapies becoming available, which correct the underlying defect causing CF

    Chronic liver disease is one of the major complications of cystic fibrosis (CF). Significant liver disease is seen in 13-25% of children with CF. Improved life expectancy and prolonged follow-up have favored better characterization of the hepatic manifestations of CF and allowed direct observation of an increasing number of liver-related events. Liver disease typically develops in the first decade of life, with the incidence dropping rapidly after the age of 10 years. The wide spectrum of liver disease ranging from asymptomatic gallbladder abnormalities to biliary cirrhosis will be reviewed in this article

    Screening for cystic fibrosis (CF) is suggested in patients with rectal prolapse (RP). Little is known about the association between CF and RP in the era of newborn screening for CF. Our retrospective review showed that 3.6% of patients with RP had CF, and 3.5% of patients with CF had RP. No demographic or clinical factors appear to predict the likelihood of RP in patients with CF. Sweat chloride testing for patients with RP has a low yield in the era of newborn screening but may still need to be considered in children with RP to avoid missing the rare child with CF.

    2011-07-01

    Full Text Available Difficulties in obtaining equine frozen semen with potential fertility are recognized. This study was designed to investigate the effect of seminal plasma on frozen/thawing of eight stallion semen from different breed using the following treatments: Seminal plasma with ten-fold concentrated proteins with molecular weight above 10 kDa on frozen extender; Part of seminal plasma with proteins under 10 kDa on frozen extender; Conventional freezing, using whole seminal plasma on frozen extender. Using the parameter of 30% of seminal motility post-thawing as index of good freezability, it was verified an increased percentage of stallions that presented good freezability when semen was frozen with seminal plasma containing ten-fold concentrated proteins with molecular weight above 10 kDa on frozen extender. These results, suggested the use of seminal plasma concentrated proteins from own stallion to freezing/thawing semen.

  8. Gene therapy for cystic fibrosis.

    Science.gov (United States)

    Mueller, Christian; Flotte, Terence R

    2008-12-01

    Cystic Fibrosis (CF) is an autosomal recessive disorder due to mutations in the CF transmembrane conductance regulator (CFTR) gene that lead to defective ion transport in the conducting pulmonary airways and exocrine glands. Through a process that is not fully understood, CFTR defects predispose affected patients to chronic endobronchial infections with organisms such as Pseudomonas aeruginosa and Staphylococcus aureus. Following the discovery of the CFTR gene in 1989, CF became one of the primary targets for gene therapy research. Early enthusiasm surrounded the new field of gene therapy during most of the 1990s and it led academics and clinicians on a big effort to apply gene therapy for cystic fibrosis. Clinical studies have been pursued using recombinant adenovirus, recombinant adeno-associated virus, cationic liposomes, and cationic polymer vectors. Although to this date no dramatic therapeutic benefits have been observed, a lot of information has been gained from the pre-clinical and clinical studies that were performed. This learning curve has led to the optimization of vector technology and an appreciation of immune and mechanical barriers that have to be overcome for successful delivery.

    The iron content in seminal plasma of normal (n19), oligozoospermic (n11), azoospermic (n12), oligoasthenozoospermic (n19), and asthenozoospermic (n17) subjects was estimated by using atomic absorption spectrophotometer. The concentration of iron in normal seminal plasma varied from 265 to 365 mg%. The source of iron in seminal plasma seems to be the adnexal glands and not spermatozoa, as azoospermic semen also contained it. A statistically highly significant difference was seen when normal was compared with azoospermia and with asthenozoospermia. The necessary average wastage of iron through semen is calculated as 2.52 mg/day. This value is highly variable according to the seminal volume and frequency of ejaculation.

    Perinatal detection of neonatal suprarenal masses has increased. Here, we report an unusual case of an adrenal cystic neuroblastoma that presented as a purely cystic lesion upon initial postnatal ultrasonography (US) and showed rapid evolution to a mixed cystic and solid mass during follow-up US and MRI. We suggest a short-term (two weeks) follow-up US for neonatal adrenal cystic lesions, even if they appear as purely cystic.

    Report of 16 cases of cystic tumors of pancreas(CTP) consisting of 5 serous cystoadenomas(SC), 6 mucigenous cystoadenomas(MC) and 5 cystoadenocarcinomas(CC) pertaining to11 women and 5 men.Mean age 63 years(ranging from 44 to 89).Four of these patients were asymptomatic, 6 of them had lost between 3 and 20 kilos.One patient with a CC developed jaundice.CTPS were diagnosed by ultrasound or CT scans. CTPs were topographed ten times at the level of pancreatic head, twice in its body and four in its tail.At end of preoperative explorations conducted for the purpose of diagnosis,CTPs went undetected in four cases.The exact diagnosis of tumor nature was made during preoperative in five cases:two SCs, one MC and two CCs. Unequivocal diagnosis was made through the histological study of surgical specimen in eleven cases,by the existence of liver metastases in one case and by citopunture under CT in the remainder.One patient refused to be operated.Thirteen patientys were operate:in four a cephalic duodenopancreatectomy was performed (1 SC and 4 MCs);in 2, a distal pancreatectomy was performed 1 MC and 1 CC); and 2 underwent surgical pucture (SCs).Asymptomatic SCs may remain unoperated under surveillance provided diagnosis be unequivocal.All other cystic tumors have to be resected, either,due to the fact that there is doubt as to their nature or because it is a symptomatic CS, or an MC or a CC.In the latter case, prognosis is better that in cases of exocrine non metastasic pancreatic cancer

    2008-01-01

    Purpose: To quantify the interfraction variability in prostate and seminal vesicle (SV) positions during a course of intensity-modulated radiotherapy (IMRT) using an integrated computed tomography (CT)-linear accelerator system and to assess the impact of rectal and bladder volume changes. Methods and Materials: We studied 15 patients who had undergone IMRT for prostate carcinoma. Patients had one pretreatment planning CT scan followed by three in-room CT scans per week using a CT-on-rails system. The prostate, bladder, rectum, and pelvic bony anatomy were contoured in 369 CT scans. Using the planning CT scan as a reference, the volumetric and positional changes were analyzed in the subsequent CT scans. Results: For all 15 patients, the mean systematic internal prostate and SV variation was 0.1 ± 4.1 mm and 1.2 ± 7.3 mm in the anteroposterior axis, -0.5 ± 2.9 mm and -0.7 ± 4.5 mm in the superoinferior axis, and 0.2 ± 0.9 mm and -0.9 ± 1.9 mm in the lateral axis, respectively. The mean magnitude of the three-dimensional displacement vector was 4.6 ± 3.5 mm for the prostate and 7.6 ± 4.7 mm for the SVs. The rectal and bladder volume changes during treatment correlated with the anterior and superior displacement of the prostate and SVs. Conclusion: The dominant prostate and SV variations occurred in the anteroposterior and superoinferior directions. The systematic prostate and SV variation between the treatment planning CT and daily therapy as a result of the rectal and bladder volume changes emphasizes the need for daily directed target localization and/or immobilization techniques

    The relationship between volume of the seminal vesicles and the frequency of sex and sexual function in middle-aged men is not clear. This study included 81 patients who were diagnosed with localized prostate cancer. Volume of the seminal vesicles was examined using a volume analyser from computed tomography. Sexual function was subjectively evaluated using the Expanded Prostate Cancer Index Composite and Erection Hardness Score. The frequency of sex was surveyed using our original questionnaire. The mean ± SD age of the patients was 67.7 ± 5.3 years. There was no relationship between the volume of seminal vesicles and age of the patients. Volume of the seminal vesicles in patients who answered that they had sexual activity at least once a year was significantly larger than in those who answered no sexual activity for several years (P < .01) Moreover, among sexually active, middle-aged men, volume of the seminal vesicles was significantly larger in those who had a sexual frequency once every 3 months than in those who had a sexual frequency once every 6 months or once a year (P < .05). Our study suggests that the volume of seminal vesicles of middle-aged men is correlated with sexual activity. © 2016 Blackwell Verlag GmbH.

    Full Text Available Background/objectives: Studies on environmental exposure to toxic metals and their effects on male reproductive function are scare in our setting. This study evaluates the levels of lead and mercury in seminal plasma of infertile males who are non-occupationally exposed in Benin City, Nigeria and to determine the relationship between seminal quality and these toxic metals. Materials and Methods: A total of 80 subjects participated in this study which includes 60 infertile males on routine visit to the infertility clinics in Benin City and 20 fertile males as controls. The concentration of lead in seminal plasma was assayed by atomic absorption spectrophotometer while the concentration of mercury was measured using inductively coupled plasma Mass spectrometry. Semen analyses were performed using standard techniques as recommended by World Health Organization. Results: Mean seminal plasma lead and mercury levels were significantly higher (p<0.001 in infertile males compared with controls. Mercury and lead correlated negatively (p<0.001 with sperm count, progressive motility, total motility and morphology but not with semen volume. There was no significant correlation between toxic metals and sperm indices in fertile males (controls. Conclusion: The levels of the studied toxic metals were higher in seminal plasma of infertile males and appear to have adverse effect on seminal indices in non -occupationally exposed males.

    To assess the effect of treatment of seminal Helicobacter pylori in infertile asthenozoospermic men. In all, 223 infertile asthenozoospermic men were consecutively selected. They were subjected to history taking, clinical examination, semen analysis, and estimation of H pylori IgA antibodies in their seminal fluid. Infertile men with high seminal H pylori IgA were subjected to triple drug treatment, omeprazole, 20 mg; tinidazole, 500 mg; and clarithromycin, 250 mg twice a day for 2 weeks. Semen analysis as well as H pylori IgA antibodies was estimated after 3 months. In all, 22 of 223 men (9.87%) demonstrated H pylori IgA antibodies in their seminal plasma. After treatment, mean seminal H pylori IgA levels demonstrated significant decrease (1.55 ± 0.4 vs 0.52 ± 0.26; 95% confidence interval, 0.83-1.21; P = .001) concomitant with improved progressive as well as nonprogressive sperm motility. H pylori IgA antibodies demonstrated significant negative correlation with progressive sperm motility, nonprogressive sperm motility, normal sperm morphology, and significant positive correlation with immotile sperm motility. H pylori treatment significantly improves sperm motility in infertile asthenozoospermic men with elevated seminal H pylori IgA. Copyright © 2014 Elsevier Inc. All rights reserved.

  4. Reproductive hacking. A male seminal protein acts through intact reproductive pathways in female Drosophila.

    2014-01-01

    Seminal proteins are critical for reproductive success in all animals that have been studied. Although seminal proteins have been identified in many taxa, and female reproductive responses to receipt of these proteins have been documented in several, little is understood about the mechanisms by which seminal proteins affect female reproductive physiology. To explore this topic, we investigated how a Drosophila seminal protein, ovulin, increases ovulation rate in mated females. Ovulation is a relatively simple physiological process, with known female regulators: previous studies have shown that ovulation rate is promoted by the neuromodulator octopamine (OA) in D. melanogaster and other insects. We found that ovulin stimulates ovulation by increasing OA signaling in the female. This finding supports a model in which a male seminal protein acts through "hacking" a well-conserved, regulatory system females use to adjust reproductive output, rather than acting downstream of female mechanisms of control or in parallel pathways altogether. We also discuss similarities between 2 forms of intersexual control of behavior through chemical communication: seminal proteins and pheromones.

    CT was undertaken and CT numbers were measured in 47 patients with cystic ovarian lesions. CT features particularly for chocolate cyst revealed the uniform thickness of the whole cystic wall, findings suggesting adhesion to the surrounding organs, circular or oval shape, and higher CT numbers within the cyst than those in the other cystic ovarian lesions. However, because these features are not always observed in cases of chocolate cyst, one should not rely solely on CT findings in the diagnosis of chocolate cyst. (Namekawa, K.)

    Several agents are used to clear secretions from the airways of people with cystic fibrosis. Mannitol increases mucociliary clearance, but its exact mechanism of action is unknown. The dry powder formulation of mannitol may be more convenient and easier to use compared with established agents which require delivery via a nebuliser. Phase III trials of inhaled dry powder mannitol for the treatment of cystic fibrosis have been completed and it is now available in Australia and some countries in Europe. This is an update of a previous review. To assess whether inhaled dry powder mannitol is well tolerated, whether it improves the quality of life and respiratory function in people with cystic fibrosis and which adverse events are associated with the treatment. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register which comprises references identified from comprehensive electronic databases, handsearching relevant journals and abstracts from conferences.Date of last search: 28 September 2017. All randomised controlled studies comparing mannitol with placebo, active inhaled comparators (for example, hypertonic saline or dornase alfa) or with no treatment. Authors independently assessed studies for inclusion, carried out data extraction and assessed the risk of bias in included studies. The quality of the evidence was assessed using GRADE. Six studies (reported in 50 publications) were included with a total of 784 participants.Duration of treatment in the included studies ranged from 12 days to six months, with open-label treatment for an additional six months in two of the studies. Five studies compared mannitol with control (a very low dose of mannitol or non-respirable mannitol) and the final study compared mannitol to dornase alfa alone and to mannitol plus dornase alfa. Two large studies had a similar parallel design and provided data for 600 participants, which could be pooled where data for a particular outcome and time point were

    Full Text Available Abstract: Symptomatic intracranial atherosclerotic disease (ICAD is responsible for approximately 10% of all ischemic strokes in the United States. The risk of recurrent stroke may be as high as 35% in patient with critical stenosis greater than 70% in diameter narrowing. Recent advances in medical and endovascular therapy have placed ICAD at the forefront of clinical stroke research to optimize the best medical and endovascular approach to treat this important underlying stroke etiology. Analysis of symptomatic ICAD studies lead to the question that whether angioplasty and or stenting is a safe, suitable and efficacious therapeutic strategy in patients with critical stenoses that are deemed refractory to medical management. Most of the currently available data in support of angioplasty and or stenting in high risk patients with severe symptomatic ICAD is in the form of case series and randomized trial results of endovascular therapy versus medical treatment are awaited. This is a comprehensive review of the state of the art in the endovascular approach with angioplasty and or stenting of symptomatic intracranial atherosclerotic disease.

    2016-01-01

    In most prostate biopsies, the seminal epithelium is easily recognised because it meets characteristic histological criteria. However, some biopsies can mimic malignant or premalignant prostatic lesions. The aims of this study were to analyse the histological appearance of the biopsies that mimic adenocarcinomas or preneoplastic prostatic lesions, discuss the differential diagnosis and determine the frequency of seminal epithelia in prostate biopsies. We consecutively reviewed 500 prostate puncture biopsies obtained using the sextant method and selected those cases in which we observed seminal vesicle or ejaculatory duct epithelium. In the biopsies in which the seminal epithelium resembled malignant or premalignant lesions, immunohistochemical studies were conducted that included prostate-specific antigen and MUC6. The most important clinical data were recorded. Thirty-six (7.2%) biopsies showed seminal epithelium, and 7 of them (1.4%) resembled various prostate lesions, including high-grade prostatic intraepithelial neoplasia, atypical acinar proliferations, adenocarcinomas with papillary patterns and poorly differentiated carcinoma. The seminal epithelium resembled prostate lesions when the lipofuscin deposit, the perinuclear vacuoles or the nuclear pseudoinclusions were inconspicuous or missing. Five of the 7 biopsies showed mild to moderate cellular atypia with small and hyperchromatic nuclei, and only 2 showed cellular pleomorphism. The patients were alive and asymptomatic after an average of 6 years of progression. The seminal epithelium resembles prostatic intraepithelial neoplasia, atypical acinar proliferations and various types of prostatic adenocarcinomas in approximately 1.4% of prostate biopsies.

  2. Lactotransferrin in Asian elephant (Elephas maximus seminal plasma correlates with semen quality.

    Directory of Open Access Journals (Sweden)

    Wendy K Kiso

    Full Text Available Asian elephants (Elephas maximus have highly variable ejaculate quality within individuals, greatly reducing the efficacy of artificial insemination and making it difficult to devise a sperm cryopreservation protocol for this endangered species. Because seminal plasma influences sperm function and physiology, including sperm motility, the objectives of this study were to characterize the chemistry and protein profiles of Asian elephant seminal plasma and to determine the relationships between seminal plasma components and semen quality. Ejaculates exhibiting good sperm motility (≥65% expressed higher percentages of spermatozoa with normal morphology (80.3±13.0 vs. 44.9±30.8% and positive Spermac staining (51.9±14.5 vs. 7.5±14.4%, in addition to higher total volume (135.1±89.6 vs. 88.8±73.1 ml and lower sperm concentration (473.0±511.2 vs. 1313.8±764.7×10⁶ cells ml⁻¹ compared to ejaculates exhibiting poor sperm motility (≤10%; P<0.05. Comparison of seminal plasma from ejaculates with good versus poor sperm motility revealed significant differences in concentrations of creatine phosphokinase, alanine aminotransferase, phosphorus, sodium, chloride, magnesium, and glucose. These observations suggest seminal plasma influences semen quality in elephants. One- and two-dimensional (2D gel electrophoresis revealed largely similar compositional profiles of seminal plasma proteins between good and poor motility ejaculates. However, a protein of ∼80 kDa was abundant in 85% of ejaculates with good motility, and was absent in 90% of poor motility ejaculates (P<0.05. We used mass spectrometry to identify this protein as lactotransferrin, and immunoblot analysis to confirm this identification. Together, these findings lay a functional foundation for understanding the contributions of seminal plasma in the regulation of Asian elephant sperm motility, and for improving semen collection and storage in this endangered species.

    Renal cystic disease includes a group of lesions with extremely diverse clinical, radiographic, and pathologic findings. The recent development of multiple imaging systems to study renal cystic disease has resulted in considerable interest in correlating the images obtained by different modalities with each other and with the underlying gross pathology. A thorough knowledge of the disturbed morphology and natural history of these diseases will lead to a better understanding of their appearance on radiologic imaging. This refresher course correlates disturbed morphology with appearances on diagnostic imaging, urography, US, angiography, CT, and MR imaging. The advantages and limitations of each imaging method are detailed. A practical classification emphasizing differential features is presented. The presentation is divided into two parts. In the first part typical and atypical cystic masses, including acquired cystic disease (from dialysis), Von Hippel-Lindau disease, and the cystic disease of tuberous sclerosis are discussed. In the second part, polycystic kidney disease (dominant and recessive), medullary cystic disease, medullary sponge kidney, multicycle-dysplastic kidney, renal sinus cysts (peripelvic), and pluricystic kidney disease are discussed

    Ring-tailed coati is listed as a species of least concern in the International Union for Conservation of Nature (IUCN) Red List, however, there has been a sharp decline in their population. The present study was conducted to evaluate the major proteins of both seminal plasma and sperm in ring-tailed coatis. Semen sample was collected from three adult coatis and evaluated for their morphological characteristics. Further, the sample was centrifuged to separate spermatozoa from seminal plasma, and then stored in liquid nitrogen. The seminal plasma and sperm proteins were subjected to one-dimensional (1-D) sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and identified by mass spectrometry. Gene ontology and protein networks were analyzed using bioinformatics tools. Based on sperm concentration and average protein content of the semen, the concentration of protein/spermatozoon was found to be 104.69 ± 44.43 μg. The analysis of SDS-PAGE gels showed 20.3 ± 3.1 and 17 ± 2 protein bands/lane for seminal plasma and sperm, respectively. In-gel protein digestion and peptide analysis by mass spectrometry revealed 238 and 246 proteins in the seminal plasma and sperm, respectively. The gene ontology analysis revealed that the proteins of seminal plasma mainly participated in cellular (35%) and regulatory (21%) processes. According to their cellular localization, seminal plasma proteins were categorized as structural (18%), extracellular (17%), and nuclear (14%) proteins with molecular functions, such as catalytic activity (43%) and binding (43%). The sperm proteins were also involved in cellular (38%) and regulatory (23%) processes, and mainly categorized as extracellular (17%), nuclear (13%), and cytoplasmic (10%) proteins. The major molecular functions of the sperm proteins were catalytic activity (44%) and binding (42%). These results indicated that the seminal plasma of ring-tailed coati has an array of proteins that can potentially

    Progressive lung disease in cystic fibrosis (CF) is the life-limiting factor of this autosomal recessive genetic disorder. Increasing implementation of CF newborn screening allows for a diagnosis even in pre-symptomatic stages. Improvements in therapy have led to a significant improvement in survival, the majority now being of adult age. Imaging provides detailed information on the regional distribution of CF lung disease, hence longitudinal imaging is recommended for disease monitoring in the clinical routine. Chest X-ray (CXR), computed tomography (CT) and magnetic resonance imaging (MRI) are now available as routine modalities, each with individual strengths and drawbacks, which need to be considered when choosing the optimal modality adapted to the clinical situation of the patient. CT stands out with the highest morphological detail and has often been a substitute for CXR for regular severity monitoring at specialized centers. Multidetector CT data can be post-processed with dedicated software for a detailed measurement of airway dimensions and bronchiectasis and potentially a more objective and precise grading of disease severity. However, changing to CT was inseparably accompanied by an increase in radiation exposure of CF patients, a young population with high sensitivity to ionizing radiation and lifetime accumulation of dose. MRI as a cross-sectional imaging modality free of ionizing radiation can depict morphological hallmarks of CF lung disease at lower spatial resolution but excels with comprehensive functional lung imaging, with time-resolved perfusion imaging currently being most valuable.

  6. Soluble human leukocyte antigen-G in seminal plasma is associated with HLA-G genotype

    PROBLEM: We have previously shown that human seminal plasma contains immunomodulatory soluble HLA-G (sHLA-G). We investigated whether sHLA-G levels in seminal plasma are associated with a specific 14 base pair (bp) insertion/deletion (ins/del) polymorphism in the 3'-untranslated region of the HLA......-G gene and/or with the outcome of assisted reproduction treatments (ART) in couples attending a fertility clinic. METHOD OF STUDY: In a total of 54 unselected couples, sHLA-G levels were measured in seminal plasma samples and blood samples, HLA-G genotyping was performed, and clinical data were collected...... for higher seminal plasma levels of sHLA-G/total protein and total sHLA-G in cases with reduced semen quality, where the female partner became pregnant after ART, compared with those couples in which no pregnancy was achieved. CONCLUSION: These first results are in accordance with a possible role of seminal...

    Homozygous beta-thalassemia is a haemolytic disorder with a high potential for oxidative damage, due to the high circulating iron levels. Enzymatic and non enzymatic antioxidant capacities, as well as lipoperoxide content, were investigated in seminal plasma of these patients to evaluate a possible oxidative stress. Semen samples from 10 transfusion-dependent beta-thalassemic patients and 18 control subjects were examined. The assessment of the seminal antioxidant capacity included spectrophotometrical assays for determination of superoxide dismutase and catalase activity and of the total antioxidant status value. Furthermore, malondialdehyde level was detected as marker of lipoperoxidation. All the beta-thalassemic patients showed high serum ferritin levels, progressive sperm motility below 50 %, and normal sperm count (median: 43 x 10 (6) sperm/ml). Increased superoxide dismutase ( p seminal plasma. Furthermore, augmented malondialdehyde levels ( p Seminal antioxidant pattern of iron overloaded beta-thalassemic patients indicated the hyperactivation of the enzymatic free-radical scavengers which could be explained as a compensatory mechanism to possible high levels of reactive oxygen species. Furthermore, the increase of seminal lipoperoxidation suggested an oxidative stress in semen of these patients and it could have contributed to the impairment of sperm motility.

    Transferrin (Tf) in fish is recognized as a component of non-specific humoral defense mechanisms against bacteria. It is a major protein of common carp seminal plasma but its structure and localization in carp testis is unknown. In this study we developed a simple and efficient three-step purification procedure consisting of affinity chromatography (Con A-Sepharose), hydrophobic interaction chromatography (Phenyl Sepharose) and gel filtration (Superdex 200). The molecular mass of Tf has been determined to be 73.6 kDa and isoelectric point 5.1. The peculiar characteristics of carp transferrin were the lack of carbohydrate component and binding of iron ions by only one functional iron-binding site. Western blot analysis revealed a strong similarity of carp seminal plasma Tf to carp blood Tf and Tf from seminal plasma of other cyprinids but a lower similarity to salmonid and percid fishes. Tf was localized to the blood vessels of the carp testis which strongly suggest that most Tf of carp seminal plasma originates from blood. In conclusion, seminal plasma Tf has a unique structure and is similar or identical to blood Tf. 2010 Elsevier Ltd. All rights reserved.

    Excessive apoptotic spermatozoon death is associated with male infertility. Leptin regulates apoptosis in several cell types. We prospectively investigated if seminal plasma leptin mediates spermatozoon apoptosis in 74 varicocele (VC) patients and 70 leucocytospermia patients. Spermatozoa from 40 normospermic men were used as controls. Routine semen analysis, spermatozoon apoptosis rate, seminal plasma leptin, reactive oxygen species (ROS) and tumour necrosis factor-alpha (TNF-α) levels were measured. In VC and leucocytospermia patients, seminal plasma leptin levels and spermatozoon apoptosis rates were significantly higher compared with controls. In the VC group, seminal plasma ROS levels were significantly higher compared with controls; there were no significant differences in TNF-α levels. In the leucocytospermia group, both ROS and TNF-α levels were significantly higher compared with controls. In both the VC and leucocytospermia groups, there was a significant positive correlation between the spermatozoon apoptosis rate and leptin levels and ROS and leptin levels. There was a significant correlation between leptin and TNF-α levels in the leucocytospermia group. Seminal plasma leptin levels correlate significantly with spermatozoon apoptosis rate, and leptin may be a spermatozoon pro-apoptotic factors. The generation of ROS is a possible mechanism. Leptin may induce apoptosis via TNF-α in leucocytospermia patients. © 2014 Blackwell Verlag GmbH.

    Full Text Available The connection between human papillomavirus (HPV infection and the consequent sequelae which establishes cervical neoplastic transformation and invasive cervical cancer has redefined many aspects of cervical cancer research. However there is still much that we do not know. In particular, the impact of external factors, like seminal fluid in sexually active women, on pathways that regulate cervical inflammation and tumorigenesis, have yet to be fully understood. HPV infection is regarded as the initiating noninflammatory cause of the disease; however emerging evidence points to resident HPV infections as drivers of inflammatory pathways that play important roles in tumorigenesis as well as in the susceptibility to other infections such as human immunodeficiency virus (HIV infection. Moreover there is emerging evidence to support a role for seminal fluid, in particular, the inflammatory bioactive lipids, and prostaglandins which are present in vast quantities in seminal fluid in regulating pathways that can exacerbate inflammation of the cervix, speed up tumorigenesis, and enhance susceptibility to HIV infection. This review will highlight some of our current knowledge of the role of seminal fluid as a potent driver of inflammatory and tumorigenic pathways in the cervix and will provide some evidence to propose a role for seminal plasma prostaglandins in HIV infection and AIDS-related cancer.

    Seminal roots are initiated at the scutellar node during maize (Zea mays L.) embryo development. The maize mutant rtcs (rootless concerning crown and seminal roots) does not initiate seminal roots while its wild-type siblings form on average 2.9 seminal roots per seedling. In this study, proteome profiles of 25-day-old immature maize embryos were compared between wild-type and rtcs plants via two-dimensional electrophoresis (2-DE). Electrospray ionization tandem mass spectrometry (ESI-MS/MS) identified 23 proteins encoded by 21 different genes that were differentially accumulated between wild-type and rtcs embryos (Fc> or =2; FDRenergetics in plants. Comparison of embryonic proteins differentially accumulated between wild-type and rtcs embryos revealed little overlap with proteins differentially accumulated between wild-type and rum1 embryos which also do not initiate seminal roots. This might be due to distinct influences of RTCS and RUM1 on the composition of the embryo proteome, but could also be explained by different stages of embryo development that were analyzed in these studies.

    The most serious complications of cystic fibrosis (CF) relate to respiratory insufficiency. Oxygen supplementation therapy has long been a standard of care for individuals with chronic lung diseases associated with hypoxemia. Physicians commonly prescribe oxygen therapy for people with CF when hypoxemia occurs. However, it is unclear if empiric evidence is available to provide indications for this therapy with its financial costs and often profound impact on lifestyle. To assess whether oxygen therapy improves the longevity or quality of life of individuals with CF. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register, comprising references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Latest search of Group's Trials Register: 15 May 2013. Randomized or quasi-randomized controlled trials comparing oxygen, administered at any concentration, by any route, in people with documented CF for any time period. Authors independently assessed the risk of bias for included studies and extracted data. This review includes 11 published studies (172 participants); only one examined long-term oxygen therapy (28 participants). There was no statistically significant improvement in survival, lung, or cardiac health. There was an improvement in regular attendance at school or work in those receiving oxygen therapy at 6 and 12 months. Four studies examined the effect of oxygen supplementation during sleep by polysomnography. Although oxygenation improved, mild hypercapnia was noted. Participants fell asleep quicker and spent a reduced percentage of total sleep time in rapid eye movement sleep, but there were no demonstrable improvements in qualitative sleep parameters. Six studies evaluated oxygen supplementation during exercise. Again, oxygenation improved, but mild hypercapnia resulted. Participants receiving oxygen therapy were able to exercise for a

    Theoretically, cystic fibrosis transmembrane conductance regulator (CFTR) gene replacement during the neonatal period can decrease morbidity and mortality from cystic fibrosis (CF). In vivo gene transfers have been accomplished in CF patients. Choice of vector, mode of delivery to airways, translocation of genetic information, and sufficient expression level of the normalized CFTR gene are issues that currently are being addressed in the field. The advantages and limitations of viral vectors are a function of the parent virus. Viral vectors used in this setting include adenovirus (Ad) and adeno-associated virus (AAV). Initial studies with Ad vectors resulted in a vector that was efficient for gene transfer with dose-limiting inflammatory effects due to the large amount of viral protein delivered. The next generation of Ad vectors, with more viral coding sequence deletions, has a longer duration of activity and elicits a lesser degree of cell-mediated immunity in mice. A more recent generation of Ad vectors has no viral genes remaining. Despite these changes, the problem of humoral immunity remains with Ad vectors. A variety of strategies such as vector systems requiring single, or widely spaced, administrations, pharmacologic immunosuppression at administration, creation of a stealth vector, modification of immunogenic epitopes, or tolerance induction are being considered to circumvent humoral immunity. AAV vectors have been studied in animal and human models. They do not appear to induce inflammatory changes over a wide range of doses. The level of CFTR messenger RNA expression is difficult to ascertain with AAV vectors since the small size of the vector relative to the CFTR gene leaves no space for vector-specific sequences on which to base assays to distinguish endogenous from vector-expressed messenger RNA. In general, AAV vectors appear to be safe and have superior duration profiles. Cationic liposomes are lipid-DNA complexes. These vectors generally have been

    Approximately 28% of the patients with cystic fibrosis are affected by cholelythiasis. More than 40% of them have a symptomatic disease, which would mandate cholecystectomy. The aim of this study was to review surgical and respiratory outcomes and quality of life scores of cystic fibrosis patients undergoing laparoscopic cholecystectomy for symptomatic cholelythiasis to verify the hypothesis that cholecystectomy is a low-risk operation by laparoscopy, not affecting unfavorably respiratory function and quality of life. Study group was consisted of 9 patients with a mean age of 24.8±8.1 years (range, 15 to 38 y), 2 male and 7 female patients, with cystic fibrosis and symptomatic cholelithiasis. Three patients also presented common bile duct stones. All the patients underwent perioperative Positive End-Expiratory Pressure mask sessions and aggressive antibiotic regimens. At the middle of the antibiotics regimen period, a standard laparoscopic cholecystectomy was performed. In the 3 cases with common duct lithiasis, the so-called "rendezvous" technique was carried out. Preoperatively, intraoperatively, and postoperatively, respiratory function was strictly monitored by the evaluation of SO2 and of the forced expiratory volume in 1 second (FEV1). Preoperatively and 6 months after laparoscopic cholecystectomy the Gastro Intestinal Quality of Life Index was evaluated on all patients. All the operations were completed laparoscopically. No mortality was observed. The intraoperative mean SO2 was 89.0%±5.6% (range, 80% to 95%), versus 82.8%±8.5% (range, 66% to 91%) at the extubation (P=0.006). Intraoperative respiratory functions were stable in 6 patients. In 3 patients, a severe bronchospasm occurred determining marked desaturation. Preoperative mean FEV1 was 70.5%±7.0% (range, 55% to 75%) versus 61.8%±13.2% (range, 39% to 80%) 48 hours after the operation (P=0.132). The 3 patients, who experienced intraoperatively severe bronchospasm, reported a 48 hours postoperative

    In this research, the concentration and activity of oxidants and anti-oxidants in turbot semen, and their effects on sperm quality were studied. The results showed that superoxide dismutase (SOD), catalase, glutathione reductase (GR), uric acid, vitamin E (VE) and vitamin C (VC) were more abundant in seminal plasma than in spermatozoa. The variation for each of them was specific. In seminal plasma, the activity of SOD and GR increased from November 15, November 30 to December 15, and then decreased on December 30. The concentrations of both VC and uric acid decreased during the first 3 sampling times and increased on December 30. The oxidants in seminal plasma accumulated to the highest on December 30. Lactic acid (LA) and ATP levels decreased to the lowest on December 30. The correlation analysis showed that GR had the significant positive relevance to sperm motility and VSL/VCL, while ·OH had negative relevance to them.

    The clinical fertility tests, available in the market, fail to define the exact cause of male infertility in almost half of the cases and point toward a crucial need of developing better ways of infertility investigations. The protein biomarkers may help us toward better understanding of unknown cases of male infertility that, in turn, can guide us to find better therapeutic solutions. Many clinical attempts have been made to identify biomarkers of male infertility in sperm proteome but only few studies have targeted seminal plasma. Human seminal plasma is a rich source of proteins that are essentially required for development of sperm and successful fertilization. This viewpoint article highlights the importance of human seminal plasma proteome in reproductive physiology and suggests that differential proteomics integrated with functional analysis may help us in searching potential biomarkers of male infertility. © 2012 WILEY-VCH Verlag GmbH & Co.

    We report on a remarkable diagnostic work up of suspect rectal palpation results in a 54-year-old patient. According to a transrectal ultrasound-guided punch biopsy the patient was suspected of having a carcinoma of the seminal vesicles and an aggressive operational approach was considered. After a median laparotomy a generalized peritoneal carcinomatosis was found. A goblet cell carcinoid of the vermiform appendix was identified as the primary tumor. This case report deals with metastazation of a primary goblet cell carcinoma into the seminal vesicles on both sides as an extremely rare reason for suspicious rectal palpation results. The tumor valency, diagnostic work up, therapy and further differential diagnoses are described.

    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.

    Cystic fibrosis (CF), a monogenic disease caused by mutations in the CFTR gene on chromosome 7, is complex and greatly variable in clinical expression. Airways, pancreas, male genital system, intestine, liver, bone, and kidney are involved. The lack of CFTR or its impaired function causes fat malabsorption and chronic pulmonary infections leading to bronchiectasis and progressive lung damage. Previously considered lethal in infancy and childhood, CF has now attained median survivals of 50 years of age, mainly thanks to the early diagnosis through neonatal screening, recognition of mild forms, and an aggressive therapeutic attitude. Classical treatment includes pancreatic enzyme replacement, respiratory physiotherapy, mucolitics, and aggressive antibiotic therapy. A significant proportion of patients with severe symptoms still requires lung or, less frequently, liver transplantation. The great number of mutations and their diverse effects on the CFTR protein account only partially for CF clinical variability, and modifier genes have a role in modulating the clinical expression of the disease. Despite the increasing understanding of CFTR functioning, several aspects of CF need still to be clarified, e.g., the worse outcome in females, the risk of malignancies, the pathophysiology, and best treatment of comorbidities, such as CF-related diabetes or CF-related bone disorder. Research is focusing on new drugs restoring CFTR function, some already available and with good clinical impact, others showing promising preliminary results that need to be confirmed in phase III clinical trials.

    Hepatic cysts are increasingly found as a mere coincidence on abdominal imaging techniques, such as ultrasonography (USG), computed tomography (CT) and magnetic resonance imaging (MRI). These cysts often present a diagnostic challenge. Therefore, we performed a review of the recent literature and developed an evidence-based diagnostic algorithm to guide clinicians in characterising these lesions. Simple cysts are the most common cystic liver disease, and diagnosis is based on typical USG characteristics. Serodiagnostic tests and microbubble contrast-enhanced ultrasound (CEUS) are invaluable in differentiating complicated cysts, echinococcosis and cystadenoma/cystadenocarcinoma when USG, CT and MRI show ambiguous findings. Therefore, serodiagnostic tests and CEUS reduce the need for invasive procedures. Polycystic liver disease (PLD) is arbitrarily defined as the presence of > 20 liver cysts and can present as two distinct genetic disorders: autosomal dominant polycystic kidney disease (ADPKD) and autosomal dominant polycystic liver disease (PCLD). Although genetic testing for ADPKD and PCLD is possible, it is rarely performed because it does not affect the therapeutic management of PLD. USG screening of the liver and both kidneys combined with extensive family history taking are the cornerstone of diagnostic decision making in PLD. In conclusion, an amalgamation of these recent advances results in a diagnostic algorithm that facilitates evidence-based clinical decision making. PMID:23801855

    Full Text Available Introduction: Cystic fibrosis is one of the most common autosomal recessive diseases that affects sweat glands and mucosa. CF is a hereditary disease with annual incidence of about 2500 new cases in United Kingdom. Insulin-like growth factor-1 (IGF-1 and insulin-like growth factor binding protein-3 levels decrease in CF. The aim of this study was to assess the role of growth peptides in patients with CF. Method: We searched PubMed, Google scholar, IranMedex, and Scientific Information Database (SID in September 2012 to April 2014. We included clinical studies with available abstracts and full texts that were in English or Persian languages. Manual searching was conducted within the reference lists of articles. Two reviewers independently applied eligibility criteria, assessed quality, and extracted data.Result: The earliest study was published in 1997 and the most recent one was in 2014. Study participants were adults in 3 studies (20% and 12 studies (80% were conducted in children. Patients with CF have lower levels of IGF-1 and there is a significant correlation between IGF-1 levels and growth index in patients with CF.Conclusions: IGF-1 decreases in children with CF and might be the cause of poor growth and low body mass index in these children.

  6. TRY-5 is a sperm-activating protease in Caenorhabditis elegans seminal fluid.

    Directory of Open Access Journals (Sweden)

    Joseph R Smith

    2011-11-01

    Full Text Available Seminal fluid proteins have been shown to play important roles in male reproductive success, but the mechanisms for this regulation remain largely unknown. In Caenorhabditis elegans, sperm differentiate from immature spermatids into mature, motile spermatozoa during a process termed sperm activation. For C. elegans males, sperm activation occurs during insemination of the hermaphrodite and is thought to be mediated by seminal fluid, but the molecular nature of this activity has not been previously identified. Here we show that TRY-5 is a seminal fluid protease that is required in C. elegans for male-mediated sperm activation. We observed that TRY-5::GFP is expressed in the male somatic gonad and is transferred along with sperm to hermaphrodites during mating. In the absence of TRY-5, male seminal fluid loses its potency to transactivate hermaphrodite sperm. However, TRY-5 is not required for either hermaphrodite or male fertility, suggesting that hermaphrodite sperm are normally activated by a distinct hermaphrodite-specific activator to which male sperm are also competent to respond. Within males, TRY-5::GFP localization within the seminal vesicle is antagonized by the protease inhibitor SWM-1. Together, these data suggest that TRY-5 functions as an extracellular activator of C. elegans sperm. The presence of TRY-5 within the seminal fluid couples the timing of sperm activation to that of transfer of sperm into the hermaphrodite uterus, where motility must be rapidly acquired. Our results provide insight into how C. elegans has adopted sex-specific regulation of sperm motility to accommodate its male-hermaphrodite mode of reproduction.

    Objective: To investigate the CT spectral imaging features of pancreatic serous oligocystic adenoma and mucinous cystic neoplasms and to assess the value of spectral CT in differentiating between pancreatic serous oligocystic adenoma and mucinous cystic neoplasms. Methods: From Feb. 2010 to Dec. 2010, 27 patients with cystic neoplasms of the pancreas (group one with 15 serous oligocystic adenomas and group two with 12 mucinous cystic neoplasms) underwent dual-phase CT spectral imaging followed by surgery. Quantitative values (age, tumor size, CT value change as function of photon energy, effective-Z, iodine-water concentration, and calcium-water concentration) were compared with independent samples t test and Mann-Whitney test and non-quantitative parameters (gender, symptom, and tumor location) were compared with Chi-square test (Fisher exact). The parameters with significant differences between two groups were analyzed further and the performance of multiple parameters for joint differential diagnosis was evaluated with discriminant analysis. Results: Compared to patients with mucinous cystic neoplasms, patients with serous oligocystic adenoma had younger age, lower frequency of being symptomatic and smaller tumor size. The CT values on 40 keV to 60 keV (with 10 keV increment) in late arterial phase [(36±13) HU vs. (62±23) HU, (26±8) HU vs. (40±15) HU, and (19±6) HU vs. (27±10) HU respectively] and 40 keV to 50 keV (with 10 keV increment) in portal venous phase [(43±14) HU vs. (61±25) HU and (30±10) HU vs. (40±16) HU respectively], effective-Z (late arterial phase 7.80± 0.16 vs. 8.05±0.21, and portal venous phase 7.87±0.15 vs 8.02±0.22), concentration of calcium (water) [late arterial phase (5±3) g/L vs. (11±4) g/L, t=-3.836, P=0.001 and portal venous phase (7±3) g/L vs. (10±5) g/L, t=-2.071, P=0.049] and iodine (water) [late arterial phase (0.38±0.24) g/L vs. (0.78±0.32) g/L, t=-3.755, P=0.001 and portal venous phase (0.48± 0.24) g/L vs. (0

    The primary imaging modality for evaluation of ovarian cystic lesions is pelvic ultrasonography. Most ovarian cysts are benign and demonstrate typical sonographic features that support benignity. However, some ovarian cystic lesions have indeterminate imaging features, and the approach to management varies. This article discusses how to recognize and diagnose different types of ovarian cystic lesions, including an approach to management. The learning objective is to recognize imaging features of ovarian cystic lesions. Copyright © 2013 Elsevier Inc. All rights reserved.

    Three cases of cystic astrocytomas are reported in children. Two are supratentorial and one is a cerebellar tumor. The authors insist on the difficulties of the diagnosis. They emphasize the role of NMR which enables distinction between cystic astrocytomas and other cysts. In agreement with Kjos, the 3 cystic astrocytomas demonstrate an increased T1 and T2 and belong to the group of cystic tumors (type II) [fr

    1985-09-01

    Seminal plasma antioxidant inhibited ascorbate/iron-induced lipid peroxidation in spermatozoa, brain and liver mitochondria. The concentration required to produce inhibition in brain and liver mitochondria was high. Denaturation of spermatozoa resulted in complete loss of antioxidant action. Maintenance of native structure was essential for action of seminal plasma antioxidant in spermatozoal lipid peroxidation. The antioxidant inhibited NADPH, Fe3+-ADP induced lipid peroxidation in microsomes and consequences of lipid peroxidation such as glucose-6-phosphatase inactivation were prevented by presence of antioxidant. It did not inhibit microsomal lipid peroxidation induced by ascorbate and iron and xanthine-xanthine oxidase.

    The aim of this study was to investigate the effect of dog semen dialysis on sperm characteristics and some biochemical components of seminal plasma. Whole ejaculates were dialyzed against Tris-citrate-fructose extender for a 5 h period at room temperature (using semi-permeable cellulose tubing of 12-14 kDa molecular weight cut-off). It has been demonstrated that the long-term dialysis of dog semen causes a significant decrease in sperm quality parameters and disrupts the biochemical properties of seminal plasma. This procedure requires further improvement.

    Purpose: To identify prostate cancer patients who will have the most likely benefit from sparing the seminal vesicles during 3D conformal radiation therapy. Methods and materials: From 1988 to 2001, 532 patients underwent radical prostatectomy for clinically localized prostate cancer. Primary endpoint was the pathological evidence of seminal vesicle invasion. Variables for univariate and multivariate analyses were age, prostate weight, clinical stage, PSA level, Gleason score, number and site of positive prostate sextant biopsies. Multivariate logistic regression with backward stepwise variable selection was used to identify a set of independent predictors of seminal vesicle invasion, and the variable selection procedure was validated by non-parametric bootstrap. Results: Seminal vesicle invasion was reported in 14% of the cases. In univariate analysis, all variables except age and prostate weight were predictors of seminal vesicle invasion. In multivariate analysis, only the number of positive biopsies (P<0.0001), Gleason score (P<0.007) and PSA (P<0.0001) were predictors for seminal vesicles invasion. Based on the multivariate model, we were able to develop a prognostic score for seminal vesicle invasion, which allowed us to discriminate two patient groups: A group with low risk of seminal vesicles invasion (5.7%), and the second with a higher risk of seminal vesicles invasion (32.7%). Conclusions: Using the number of positive biopsies, Gleason score and PSA, it is possible to identify patients with low risk of seminal vesicles invasion. In this population, seminal vesicles might be excluded as a target volume in radiation therapy of prostate cancer

    2018-02-01

    There are limited data from randomized clinical trials to guide optimal options for pharmacological treatment of cystic fibrosis related diabetes (CFRD). Current guidelines recommend insulin as the only treatment option for CFRD. Areas covered: Current guidelines for screening, diagnosis and pharmacological agents for treatment of impaired glucose tolerance and CFRD in patients with cystic fibrosis are reviewed. Insights from clinical studies examining the role of insulin therapy in CFRD are presented. Expert commentary: CFRD is the most common extra pulmonary complication of cystic fibrosis, and is primarily related to insulin insufficiency. Insulin is the treatment of choice for CFRD. Insulin treatment is associated with improvement in glycemic control, nutritional status and lung function. Current data does not support use of oral hypoglycemic agents for treatment of CFRD.

    Full Text Available The calcifying cystic odontogenic tumor normally presents as apainless, slow-growing mass, involving both maxilla and mandible,primarily the anterior segment (incisor/canine area. It generallyaffects young adults in the third to fourth decades, with no genderpredilection. Computerized tomography images revealed importantcharacteristics that were not detected by panoramic radiography,such as fenestration, calcification and tooth-like structures. Thetypical microscopic feature of this lesion is the presence of variableamounts of aberrant epithelial cells, without nuclei, which arenamed “ghost cells”. In addition, dysplastic dentine can be foundand occasionally the cyst can be associated with an area of dentalhard tissue formation resembling an odontoma. The treatment forcalcifying cystic odontogenic tumor involves simple enucleationand curettage. The purpose of this article is to present two differentmanifestation of calcifying cystic odontogenic tumor in whichcomputerized tomography, associated to clinical features, servedas an important tool for diagnosis, adequate surgical planning andfollow-up of patients.

    2010-01-01

    This review highlights the changes that have occurred in the general approach to cystic renal diseases in children. For instance, genetic mutations at the level of the primary cilia are considered as the origin of many renal cystic diseases. Furthermore, these diseases are now included in the spectrum of the hepato-renal fibrocystic diseases. Imaging plays an important role as it helps to detect and characterize many of the cystic diseases based on a detailed sonographic analysis. The diagnosis can be achieved during fetal life or after birth. Hyperechoic kidneys and/or renal cysts are the main sonographic signs leading to such diagnosis. US is able to differentiate between recessive and dominant polycystic kidney diseases, hepatocyte nuclear factor 1 Beta mutation, glomerulocystic kidneys and nephronophtisis. MR imaging can, in selected cases, provide additional information including the progressive associated hepatic changes. (orig.)

    Enteral tube feeding is routinely used in many cystic fibrosis centres when oral dietary and supplement intake has failed to achieve an adequate nutritional status. The use of this method of feeding is assessed on an individual basis taking into consideration the patients age and clinical status. To examine the evidence that in people with cystic fibrosis, supplemental enteral tube feeding improves nutritional status, respiratory function, and quality of life without significant adverse effects. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register which comprises references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings. We also contacted the companies that market enteral feeds and reviewed their databases.Date of the most recent search of the Group's Cystic Fibrosis Trials Register: 13 February 2015.Date of the most recent hand search of PubMed and conference abstract books: 13 February 2015. All randomised controlled trials comparing supplemental enteral tube feeding for one month or longer with no specific intervention in people with cystic fibrosis. The searches identified 38 trials; however, none were eligible for inclusion in this review. There are no trials included in this review. Supplemental enteral tube feeding is widely used throughout the world to improve nutritional status in people with cystic fibrosis. The methods mostly used, nasogastric or gastrostomy feeding, are expensive and may have a negative effect on self-esteem and body image. Reported use of enteral tube feeding suggests that it results in nutritional and respiratory improvement; but, efficacy has not been fully assessed by randomised controlled trials. It is acknowledged, however, that performing a randomised controlled trial would be difficult due to the ethics of withholding an intervention in a group of patients whose nutritional status necessitates it.

    Context Cystic fibrosis (CF) is the most widespread autosomal recessive genetic disorder that limits life expectation amongst the Caucasian population. As the median survival has increased related to early multidisciplinary intervention, other manifestations of CF have emergedespecially for the broad spectrum of hepatobiliary involvement. The present study reviews the existing literature on liver disease in cystic fibrosis and describes the key issues for an adequate clinical evaluation and management of patients, with a focus on the pathogenetic, clinical and diagnostic-therapeutic aspects of liver disease in CF. Evidence Acquisition A literature search of electronic databases was undertaken for relevant studies published from 1990 about liver disease in cystic fibrosis. The databases searched were: EMBASE, PubMed and Cochrane Library. Results CF is due to mutations in the gene on chromosome 7 that encodes an amino acidic polypeptide named CFTR (cystic fibrosis transmembrane regulator). The hepatic manifestations include particular changes referring to the basic CFTR defect, iatrogenic lesions or consequences of the multisystem disease. Even though hepatobiliary disease is the most common non-pulmonary cause ofmortalityin CF (the third after pulmonary disease and transplant complications), only about the 33%ofCF patients presents clinically significant hepatobiliary disease. Conclusions Liver disease will have a growing impact on survival and quality of life of cystic fibrosis patients because a longer life expectancy and for this it is important its early recognition and a correct clinical management aimed atdelaying the onset of complications. This review could represent an opportunity to encourage researchers to better investigate genotype-phenotype correlation associated with the development of cystic fibrosis liver disease, especially for non-CFTR genetic polymorphisms, and detect predisposed individuals. Therapeutic trials are needed to find strategies of

    The diagnosis of cystic fibrosis (CF) is being made with increasing frequency in adults. Patients with CF diagnosed in adulthood typically present with respiratory complaints, and often have recurrent or chronic airway infection. At the time of initial presentation individuals may appear to have clinical manifestation limited to a single organ, but with subclinical involvement of the respiratory tract. Adult-diagnosed patients have a good response to CF center care, and newly available cystic fibrosis transmembrane receptor-modulating therapies are promising for the treatment of residual function mutation, thus increasing the importance of the diagnosis in adults with unexplained bronchiectasis.

    In the first instance, polyneuropathies are treated causally. The most common underlying cause is diabetes mellitus or alcohol abuse. In a large number of patients with polyneuropathy, however, the underlying cause cannot be definitively identified. For these--but equally for patients with etiologically clear polyneuropathy--a stock-taking of clinical symptoms should be carried out and, where indicated, symptomatic treatment initiated. In addition to medication aimed at combating pain, muscular spasm, autonomic functional disorders, and for the prevention of thrombosis, physical measures (physiotherapy, foot care, orthopedic shoes) are of primary importance.

    The aim of the present study was to measure zinc (Zn) and iron (Fe) concentration in human semen and superoxide dismutase (SOD) activity in seminal plasma and correlate the results with sperm quality. Semen samples were obtained from men (N = 168) undergoing routine infertility evaluation. The study design included two groups based on the ejaculate parameters. Group I (n = 39) consisted of males with normal ejaculate (normozoospermia), and group II (n = 129) consisted of males with pathological spermiogram. Seminal Zn and Fe were measured in 162 samples (group I, n = 38; group II, n = 124) and SOD activity in 149 samples (group I, n = 37; group II, n = 112). Correlations were found between SOD activity and Fe and Zn concentration, and between Fe and Zn concentration. SOD activity was negatively associated with volume of semen and positively associated with rapid progressive motility, nonprogressive motility, and concentration. Negative correlation was stated between Fe concentration and normal morphology. Mean SOD activity in seminal plasma of semen from men of group I was higher than in seminal plasma of semen from men of group II. Fe concentration was higher in teratozoospermic males than in males with normal morphology of spermatozoa in group II. Our results suggest that Fe may influence spermatozoa morphology.

    The spermatozoon ultrastructure in the seminal receptacle of the liver fluke Opisthorchis felineus (Digenea, Opisthorchiidae), the agent of human opisthorchiasis endemic to Russia and Eastern Europe, was examined. The bean-shaped seminal receptacle of O. felineus has a wall consisting of epithelial and muscle layers. Mature spermatozoa are located in the interior of the seminal receptacle, whereas vacuoles containing degenerating spermatozoa are detectable at the periphery. The mature spermatozoon of O. felineus has two axonemes of a 9 + "1" pattern, a nucleus, two mitochondria, a lamellar body, two bundles of parallel cortical microtubules and an external ornamentation of the plasma membrane in the anterior area of the sperm. The lamellar body is likely to be the third mitochondrion of a small size. The cytoplasm of the spermatozoon is filled with numerous electron-dense granules of storage polysaccharides. Additionally, the ultrastructural characteristics of the seminal receptacle and spermatozoa of O. felineus were compared to available published data on other trematode species. The functional roles of the observed structures of this spermatozoon are discussed.

    2016-01-01

    To understand the mechanisms underlying ejaculation dysfunction caused by α1A-adrenocetor (AR) antagonists, the effects of α1A-AR antagonists on the contractile responses of the seminal vesicle were investigated. Isolated seminal vesicles from guinea pigs were cannulated and pressurized, and the changes in the intraluminal pressure were recorded. Periodic applications of electrical stimulation (ES) caused biphasic increase in the intraluminal pressure, that is, initial and subsequent contractions. The effects of silodosin and tamsulosin, α1A-AR antagonists, on the contractile responses were examined. The ES-induced biphasic contractions were blocked by tetrodotoxin (TTX). Silodosin and tamsulosin suppressed the initial contractions in a dose-dependent manner, while also exerting various inhibitory effects on the subsequent contractions. Increases in the intraluminal pressure facilitated spontaneous phasic contractions. The spontaneous contractions were not affected by TTX or α1A-AR antagonists, but were abolished by nifedipine. The initial contractions triggered by neuronal excitations were suppressed by silodosin and tamsulosin, suggesting that the ejaculation dysfunction may be attributed to the α1A-AR antagonist-mediated suppression of nerve-evoked contractions in the seminal vesicle. The subsequent contractions may be induced by mechanical stimulation associated with the initial, nerve-evoked contractions. Alternatively, other transmitters may be involved to various degrees in the neuromuscular transmission of the seminal vesicle. © 2014 Wiley Publishing Asia Pty Ltd.

    Anti-Müllerian hormone (AMH) also known as Müllerian inhibiting substance or factor, is a Sertoli cell-secreted glycoprotein responsible in male embryos for Müllerian duct regression. However, its role in adults remains unknown. AMH seminal concentrations have been evaluated using an enzyme-linked immunoassay in three groups of young men: group 1, fertile donors (n = 18); group 2, obstructive azoospermia (n = 9) after vasectomy or associated with deferent duct agenesia; and group 3, non-obstructive azoospermia with spermatogenesis deficiency and normal karyotype (n = 23). AMH was present in seminal plasma of most fertile donors at concentrations ranging from undetectable (testicular origin. In non-obstructive azoospermia (group 3), seminal AMH concentration was lower (range testicular biopsies revealed that undetectable AMH found in 14 cases was associated in 11 of them with lack of spermatozoa, while detectable concentrations of AMH (10-68.5 pmol/l) found in nine cases were associated in seven of them with persistent spermatogenesis. In the adult, AMH is secreted preferentially towards the seminiferous lumen. Although its relationship with spermatogenesis requires further investigation, our results suggest that seminal AMH may represent a non-invasive marker of persistent hypospermatogenesis in cases of non-obstructive azoospermia which may indicate the likely success of testicular spermatozoa recovery before intracytoplasmic sperm injection.

    Full Text Available The detection rate of pancreatic cystic neoplasms obviously increases with the development of imaging technology. However, it is still difficult to make the differential diagnosis between different types of pancreatic cystic neoplasms. For pancreatic cystic neoplasms, the physical condition of the patient, tumor size, location, patient preference, and other potential factors should be considered to develop an individualized treatment. The incidence rate of complications is high, although the operative mortality of pancreatic cystic neoplasms is very low. Therefore, it is necessary to strictly make the treatment decision for pancreatic cystic neoplasms.

    Full Text Available This prospective study was designed to investigate the relationship between lipids levels in both serum and seminal plasma and semen parameters.631 subfertile men were enrolled. Their obesity-associated markers were measured, and semen parameters were analyzed. Also, seminal plasma and serum TC, TG, HDL and LDL and serum FFA, FSH, LH, total testosterone (TT, estradiol (E2 and SHBG levels were detected.Seminal plasma and serum TG, TC and LDL levels were positively related to age. Serum TC, TG and LDL were positively related to obesity-associated markers (P < 0.001, while only seminal plasma TG was positively related to them (P < 0.05. For lipids levels in serum and seminal plasma, only TG level had slightly positive correlation between them (r = 0.081, P = 0.042. There was no significant correlation between serum lipids levels and semen parameters. However, seminal plasma TG, TC, LDL and HDL levels were negatively related to one or several semen parameters, including semen volume (SV, sperm concentration (SC, total sperm count (TSC, sperm motility, progressive motility (PR and total normal-progressively motile sperm counts (TNPMS. Moreover, seminal plasma TG, TC, LDL and HDL levels in patients with oligospermatism, asthenospermia and teratozoospermia were higher than those with normal sperm concentration, motility or morphology. After adjusting age and serum LH, FSH, TT, E2 and SHBG levels, linear regression analysis showed that SV was still significantly correlated with seminal plasma LDL (P = 0.012, both of SC and TSC with seminal plasma HDL (P = 0.028 and 0.002, and both of PR and sperm motility with seminal plasma TC (P = 0.012 and 0.051.The abnormal metabolism of lipids in male reproductive system may contribute to male factor infertility.

    This study aimed to examine the incidence, epidemiology, and clinical characteristics of symptomatic and asymptomatic candidiasis in a pediatric intensive care unit (PICU), and to determine the risk factors associated with symptomatic candidiasis. This retrospective study included 67 patients from a 7-bed PICU in a tertiary care hospital that had Candida-positive cultures between April 2007 and July 2009. Demographic and clinical characteristics of the patients, Candida isolates, antimicrobial and antifungal treatments, and previously identified risk factors for symptomatic candidiasis were recorded, and symptomatic and asymptomatic patients were compared. In all, 36 (53.7%) of the patients with Candida-positive cultures had asymptomatic candidiasis and 31 (46.3%) had symptomatic candidiasis. Candida albicans was the most common Candida sp. in the asymptomatic patients (n = 20, 55.6%), versus Candida parapsilosis in the symptomatic patients (n = 15, 48.4%). The incidence of central venous catheter indwelling, blood transfusion, parenteral nutrition, and surgery was higher in the symptomatic patient group than in the asymptomatic patient group (P candidiasis according to forward stepwise multivariate logistic regression analysis (OR: 6.1; 95% CI: 1.798-20.692). Surgery was the only risk factor significantly associated with symptomatic candidiasis and non-albicans Candida species were more common among the patients with symptomatic candidiasis. While treating symptomatic candidiasis in any PICU an increase in the incidence of non-albicans candidiasis should be considered.

  2. Effect of Seminal Vesicles and Dithiotritol (Dtt on Stability of Sperm Chromatin

    2005-04-01

    Full Text Available Introduction: Different studies have shown that there is no relation between sperm chromatin stability and fertilization rate in both IVF and ICSI patients. However, the relation between SDS tests, as a detergent, along with DTT as reducer of disulphide bridges has not been studied so far in ICSI patients. Since different concentrations of DTT can induce different degrees of sperm chromatin decondensation, the aim of this study was to evaluate the effect of different concentrations of DTT on sperm chromatin decondensation in IVF and ICSI cases. Methods: During this study, 85 patients were divided into two groups according to their treatment procedure (IVF or ICSI.Semen samples of each patient was evaluated for sperm chromatin tests including SDS, SDS+EDTA & SDS+DTT for assessment of free thiole groups level (-SH, amount of non covalent bond between Zn and thioles(-SH Zn SH- and levels of disulfide bond (-S-S- in sperm chromatin, respectively. In this study, seminal fructose concentration, corrected seminal fructose level and true corrected fructose level as indicators of seminal vesicle function on sperm chromatin stability were assessed. Results: No correlation was observed between any of the above tests and rate of fertilization, both in IVF and ICSI cases. However, in IVF patients, a significant correlation was observed between SDS, SDS+DTT test and seminal fructose level, while in ICSI patients, only a significant correlation was observed between SDS+DTT and corrected or true fructose concentration. Conclusion: Since no correlation was observed between sperm chromatin test and fertilization rate, it is suggested that the chromatin status of these samples are adequate for fertilization to take place and extent of disulphide bridges has no effect on fertilization rate. However, the amount of disulphide bound present in sperms of ICSI and IVF patients are different, and this difference is related to seminal vesicle performance in these patients.

  3. The Drosophila melanogaster seminal fluid protease "seminase" regulates proteolytic and post-mating reproductive processes.

    2012-01-01

    Full Text Available Proteases and protease inhibitors have been identified in the ejaculates of animal taxa ranging from invertebrates to mammals and form a major protein class among Drosophila melanogaster seminal fluid proteins (SFPs. Other than a single protease cascade in mammals that regulates seminal clot liquefaction, no proteolytic cascades (i.e. pathways with at least two proteases acting in sequence have been identified in seminal fluids. In Drosophila, SFPs are transferred to females during mating and, together with sperm, are necessary for the many post-mating responses elicited in females. Though several SFPs are proteolytically cleaved either during or after mating, virtually nothing is known about the proteases involved in these cleavage events or the physiological consequences of proteolytic activity in the seminal fluid on the female. Here, we present evidence that a protease cascade acts in the seminal fluid of Drosophila during and after mating. Using RNAi to knock down expression of the SFP CG10586, a predicted serine protease, we show that it acts upstream of the SFP CG11864, a predicted astacin protease, to process SFPs involved in ovulation and sperm entry into storage. We also show that knockdown of CG10586 leads to lower levels of egg laying, higher rates of sexual receptivity to subsequent males, and abnormal sperm usage patterns, processes that are independent of CG11864. The long-term phenotypes of females mated to CG10586 knockdown males are similar to those of females that fail to store sex peptide, an important elicitor of long-term post-mating responses, and indicate a role for CG10586 in regulating sex peptide. These results point to an important role for proteolysis among insect SFPs and suggest that protease cascades may be a mechanism for precise temporal regulation of multiple post-mating responses in females.

    Symptomatic splenic hamartomas are rare in the pediatric age group, with only four previous reports in the literature. Splenic hamartoma has been reported as a solid homogeneous mass without calcification on CT and ultrasound (US), and only one previous report of the findings on MRI has been published. We report a case of a large symptomatic splenic hamartoma in a 14-year-old girl who presented with splenomegaly, pancytopenia and growth retardation. A solid mass with multiple punctate foci resembling calcifications was seen on US. The mass was heterogeneous and better demarcated on enhanced CT. Radiocolloid scintigraphy demonstrated uptake within the lesion, but less than that of normal spleen. The mass was isointense relative to normal splenic tissue on T1-weighted MRI (0.5 T) and of increased intensity with T2 weighting. At splenectomy, a red pulp hamartoma was identified, which contained nodules of hyalinization and necrosis thought to account for the punctate foci seen on US. (orig.). With 4 figs

    Bone matastases are one of the most common and serious conditions requiring radiotherapy, but there is still a considerable lack of agreement on optimal radiation schedule. We analyzed patients with symptomatic osseous matastases from lung (72 patients) and breast (63 patients) carcinoma treated by palliative radiotherapy between 1983 and 1992. In this series, the incidences of symptomatic bone metastases appearing within 2 years after the first diagnosis of the primary lesion were 96% and 36% for lung and breast carcinomas, respectively. Thirty percent of bone metastases from breast carcinoma were diagnosed more than 5 years after the first diagnosis. Thus careful follow-up must be carried out for a prolonged period. Pain relief was achieved at almost the same rate for bone metastases from lung and breast carcinomas (81% and 85%, respectively), an the rapid onset of pain relief (15 Gy or less) was obtained in about half the patients for both diseases. The rapid onset of pain relief and the lack of association between the onset of pain relief and primary tumor argued against the conventional theory that tumor shrinkage is a component of the initial response. In contrast to the fact that almost all lung carcinoma patients had very poor prognoses, one third of the breast carcinoma patients were alive more than 2 years after palliative radiotherapy. Thust, the late effects of radiation, such as radiation myelopathy, must be always considered especially in breast carcinoma patients even when it is 'just' palliative radiotherapy for bone metastases.

    To evaluate the incidence of acute symptomatic urolithiasis in the Auckland region. Associated epidemiological factors and stone characteristics were also studied and compared to previous research conducted in order to analyse trends. All patients that presented acutely with symptomatic urolithiasis to the Auckland District Health Board (AHDB) between July 2014 and June 2015 were studied. Clinical data was obtained from medical records and population data was based on estimates provided by the Ministry of Health. Two-tailed tests and the Pearson Chi-Square tests were used for analysis. Overall, 1,125 patients (1,328 events) presented with an incidence of 85 per 100,000 per year, which was lower than that reported in 2006. The highest incidence was found among the Middle Eastern ethnic subgroup (0.130 %), followed by Māori (0.102%), Asian (0.087%), European (0.084%) and Pacific (0.041%) ethnicity. Males were more likely to be affected than females. Urolithiasis was most common in the fifth decade of life (25%). Forty-seven percent of the study population presented with multiple stones and 64% had recurrent urolithiasis or were 'high risk' stone formers. Distal ureteric stones Auckland. This deviation could be attributed to the large influx of Asian immigrants observed in this period of time. A caucasian male, between 40-49 years, with a calculus <5mm in the distal ureter with a history of a previous urolithiasis has the highest chance to present with renal colic.

  8. The diagnosis of cystic fibrosis.

    Establishing the diagnosis of cystic fibrosis (CF) is straight forward in the majority of patients: they present with a clear clinical picture (most frequently chronic respiratory symptoms plus malabsorption), the sweat chloride value is>60mmol/L and two known disease causing CFTR mutations are identified. In less than 5% of subjects, mainly those with a milder or limited phenotype, the diagnostic process is more complex, because initial diagnostic test results are inconclusive: sweat chloride concentration in the intermediate range, less than 2 CF causing mutations identified or both. These patients should be referred to expert centers where bioassays of CFTR function like nasal potential difference measurement or intestinal current measurement can be done. Still, in some patients, despite symptoms compatible with CF and some indication of CFTR dysfunction (e.g. only intermediate sweat chloride value), diagnostic criteria are not met (e.g. only 1 CFTR mutation identified). For these subjects, the term CFTR related disorder (CFTR-RD) is used. Patients with disseminated bronchiectasis, congenital bilateral absence of the vas deferens and acute or recurrent pancreatitis may fall in this category. CF has a very wide disease spectrum and increasingly the diagnosis is being made during adult life, mainly in subjects with milder phenotypes. In many countries, nationwide CF newborn screening (NBS) has been introduced. In screen positive babies, the diagnosis of CF must be confirmed by a sweat test demonstrating a sweat chloride concentration above 60mmol/L. To achieve the benefit of NBS, every baby in whom the diagnosis of CF is confirmed must receive immediate follow-up and treatment in a CF reference center. CF NBS is not full proof: some diagnoses will be missed and in some babies the diagnosis cannot be confirmed nor ruled out with certainty. Screening algorithms that include gene sequencing will detect a high number of such babies that are screen positive with an

  9. Laryngeal adenoid cystic carcinoma: case report

    Directory of Open Access Journals (Sweden)

    André Del Negro

    Full Text Available CONTEXT: Adenoid cystic carcinomas are malignant tumors that occur in both the major and the minor salivary glands. A laryngeal location is rare because of the paucity of accessory salivary glands in this area. Adenoid cystic carcinomas account for less than 1% of all malignant tumors in the larynx, and only about 120 cases have been reported in the literature. These tumors have a slight female predisposition, and their peak incidence is in the fifth and sixth decades of life. In this article, we describe a case of laryngeal adenoid cystic carcinoma and discuss its clinical characteristics and treatment. CASE REPORT: We report on a case of laryngeal adenoid cystic carcinoma in a 55 year-old female patient who presented with dyspnea and hoarseness. Features of the diagnostic and therapeutic evaluation are described and the clinical management of such cases is outlined. The clinical course, definitive treatment strategy and surgical procedure, and also adjuvant treatment with irradiation are discussed. Although the tumor is radiosensitive, it is not radiocurable.

    Immunoreactive trypsin (IRT) was measured in dried blood spots from 160.822 five-day-old babies as a part of a regionwide neonatal screening program for cystic fibrosis. A second test was performed for 492 babies in whom blood IRT levels were found greater than 900 μg/l; retesting revealed persistent elevation in 55. Sweat testing confirmed cystic fibrosis in 43 babies, but results were normal in 12. During the course of this study, a total of 51 cystic fibrosis babies were identified: 43 by newborn screening, 6 because they had meconium ileus; so, early diagnosis was achieved in 49 cases out of 51. Two newborn babies did not have elevated IRT and they were missed by the screening test. Our results confirm that elevated blood IRT is characteristic of newborn babies with cystic fibrosis and show that this test has an excellent specificity (99.7%) and a good sensitivity (95%) when used as a neonatal screening test [fr

    Nutrition is thought to influence disease status in patients with cystic fibrosis (CF). This cross-sectional study sought to evaluate nutrient intake and anthropometric data from 64 adult outpatients with cystic fibrosis. Nutrient intake from food and supplements was compared with the Dietary Reference Intakes for 16 nutrients and outcomes influenced by nutritional status. Attention was given to vitamin D and calcium given potential skeletal implications due to cystic fibrosis. Measurements included weight, height, body composition, pulmonary function, and serum metabolic parameters. Participants were interviewed about dietary intake, supplement use, pulmonary function, sunlight exposure, and pain. The participants’ mean body mass index (±standard deviation) was 21.8±4.9 and pulmonary function tests were normal. Seventy-eight percent used pancreatic enzyme replacement for malabsorption. Vitamin D deficiency [25-hydroxyvitamin D (25OHD)<37.5 nmol/L] was common: 25 (39%) were deficient despite adequate vitamin D intake. Lipid profiles were normal in the majority, even though total and saturated fat consumption represented 33.0% and 16.8% of energy intake, respectively. Reported protein intake represented 16.9% of total energy intake (range 10%–25%). For several nutrients, including vitamin D and calcium, intake from food and supplements in many participants exceeded recommended Tolerable Upper Intake Levels. Among adults with cystic fibrosis, vitamin D deficiency was common despite reported adequate intake, and lipid profiles were normal despite a relatively high fat intake. Mean protein consumption was adequate, but the range of intake was concerning, as both inadequate or excessive intake may have deleterious skeletal effects. These findings call into question the applicability of established nutrient thresholds for patients with cystic fibrosis. PMID:18060897

    To compare single-session radiofrequency ablation (RFA) and ethanol ablation (EA) for treating predominantly cystic thyroid nodules (PCTNs). This single-blind, randomized trial was approved by the Institutional Review Board of two centers and informed consent was obtained from all patients before enrollment. Fifty patients with a single PCTN (cystic portion less than 90% and greater than 50%) were randomly assigned to be treated by either RFA (25 patients) or EA (25 patients) at two hospitals. The primary outcome was the tumor volume reduction ratio (%) at the six-month follow-up and the superiority margin was set at 13% (RFA minus EA). Analysis was performed primarily in an intention-to-treat manner. The secondary outcomes were the therapeutic success rate, improvement of symptomatic and cosmetic problems, and the number of major complications. The mean volume reduction was 87.5 ± 11.5% for RFA (n = 22) and 82.4 ± 28.6% for EA (n = 24) (p = 0.710; mean difference [95% confidence interval], 5.1% [-8.0 to 18.2]), indicating no significant difference. Regarding the secondary outcomes, therapeutic success (p = 0.490), mean symptom (p = 0.205) and cosmetic scores (p = 0.710) showed no difference. There were no major complications in either group (p > 0.99). The therapeutic efficacy of RFA is not superior to that of EA; therefore, EA might be preferable as the first-line treatment for PCTNs.

    Obesity appears to be associated with male reproductive dysfunction and infertility, although this has been inconsistent and inconclusive. Insulin and leptin are known mediators and modulators of the hypothalamus-pituitary-testes axis, contributing to the regulation of male reproductive potential and overall wellbeing. These hormones are also present in semen influencing sperm functions. Although abdominal obesity is closely associated with insulin resistance (hyperinsulinaemia), hyperleptinaemia and glucose dysfunction, changes in seminal plasma concentrations of insulin, leptin and glucose in obese males has not previously been investigated. This small case controlled study assessed serum and seminal concentrations of insulin, leptin and glucose in obese (BMI > =30; n = 23) and non-obese (BMI Obesity was associated with increased serum and seminal insulin and leptin, with no significant difference in seminal glucose. Serum and seminal concentrations of insulin and leptin were positively correlated. Furthermore, obesity was associated with decreased sperm concentration, sperm vitality and increased MMP and DF, with a non-significant impact on motility and morphology. Hyperinsulinaemia and hyperleptinaemia are associated with increased seminal insulin and leptin concentrations, which may negatively impact male reproductive function in obesity. Insulin was also found to be highly concentrated in the seminal plasma of both groups. This data will contribute to the contradictive information available in the literature on the impact of obesity and male reproduction.

    Full Text Available Abstract A family of proteins designated BSP-A1, BSP-A2, BSP-A3 and BSP-30 kDa (collectively called BSP proteins for Bovine Seminal Plasma proteins constitute the major protein fraction in the bull seminal plasma. These proteins interact with choline phospholipids on the sperm surface and play a role in the membrane stabilization (decapacitation and destabilization (capacitation process. Homologous proteins have been isolated from boar and stallion seminal plasma. In the current study we report the isolation and preliminary characterization of homologous proteins from goat seminal plasma. Frozen semen (-80°C was thawed and centrifuged to remove sperm. The proteins in the supernatant were precipitated by the addition of cold ethanol. The precipitates were dissolved in ammonium bicarbonate and lyophilised. The lyophilised proteins were dissolved in phosphate buffer and loaded onto a gelatin-agarose column, which was previously equilibrated with the same buffer. The column was successively washed with phosphate buffer, with phosphate buffer saline and with 0.5 M urea in phosphate buffer saline to remove unadsorbed proteins, and the adsorbed proteins were eluted with 5 M urea in phosphate buffer saline. Analysis of pooled, dialysed and lyophilised gelatin-agarose adsorbed protein fraction by SDS-PAGE indicated the presence of four protein bands that were designated GSP-14 kDa, GSP-15 kDa, GSP-20 kDa and GSP-22 kDa (GSP, Goat Seminal Plasma proteins. Heparin-affinity chromatography was then used for the separation of GSP-20 and -22 kDa from GSP-14 and -15 kDa. Finally, HPLC separation permitted further isolation of each one from the other. Amino acid sequence analysis of these proteins indicated that they are homologous to BSP proteins. In addition, these BSP homologs bind to hen's egg-yolk low-density lipoproteins. These results together with our previous data indicate that BSP family proteins are ubiquitous in mammalian seminal plasma, exist in

    Objective This prospective study was designed to investigate the relationship between lipids levels in both serum and seminal plasma and semen parameters. Methods 631 subfertile men were enrolled. Their obesity-associated markers were measured, and semen parameters were analyzed. Also, seminal plasma and serum TC, TG, HDL and LDL and serum FFA, FSH, LH, total testosterone (TT), estradiol (E2) and SHBG levels were detected. Results Seminal plasma and serum TG, TC and LDL levels were positively related to age. Serum TC, TG and LDL were positively related to obesity-associated markers (P lipids levels in serum and seminal plasma, only TG level had slightly positive correlation between them (r = 0.081, P = 0.042). There was no significant correlation between serum lipids levels and semen parameters. However, seminal plasma TG, TC, LDL and HDL levels were negatively related to one or several semen parameters, including semen volume (SV), sperm concentration (SC), total sperm count (TSC), sperm motility, progressive motility (PR) and total normal-progressively motile sperm counts (TNPMS). Moreover, seminal plasma TG, TC, LDL and HDL levels in patients with oligospermatism, asthenospermia and teratozoospermia were higher than those with normal sperm concentration, motility or morphology. After adjusting age and serum LH, FSH, TT, E2 and SHBG levels, linear regression analysis showed that SV was still significantly correlated with seminal plasma LDL (P = 0.012), both of SC and TSC with seminal plasma HDL (P = 0.028 and 0.002), and both of PR and sperm motility with seminal plasma TC (P = 0.012 and 0.051). Conclusion The abnormal metabolism of lipids in male reproductive system may contribute to male factor infertility. PMID:26726884

    Splenic cysts are rare diseases that are diagnosed incidentally during imaging studies. When cysts are recognized, surgical treatment is recommended adapted to the particular case, depending on the size and location of the cyst and the age of the patient in order to avoid dangerous complications such as spleen rupture or cyst infection with abscess. We report 2patients with symptomatic splenic epidermoid cyst treated by laparoscopic cleavage. Laparoscopic cleavage is a surgical option for splenic cyst, with the goal of reducing postoperative complications while preserving splenic function.

    OBJECTIVE: We tested the hypothesis that low plasma concentrations of 25-hydroxyvitamin D are associated with increased risk of symptomatic ischemic stroke in the general population. METHODS: We measured plasma 25-hydroxyvitamin D in 10,170 individuals from the general population, the Copenhagen...... City Heart Study. During 21 years of follow-up, 1,256 and 164 persons developed ischemic and hemorrhagic stroke, respectively. In a meta-analysis of ischemic stroke, we included 10 studies, 58,384 participants, and 2,644 events. RESULTS: Stepwise decreasing plasma 25-hydroxyvitamin D concentrations...... were associated with stepwise increasing risk of ischemic stroke both as a function of seasonally adjusted percentile categories and as a function of clinical categories of 25-hydroxyvitamin D (p for trend ≤ 2 × 10(-3) ). In a Cox regression model comparing individuals with plasma 25-hydroxyvitamin D...

    Physical exercise training may form an important part of regular care for people with cystic fibrosis. This is an update of a previously published review. To assess the effects of physical exercise training on exercise capacity by peak oxygen consumption, pulmonary function by forced expiratory volume in one second, health-related quality of life and further important patient-relevant outcomes in people with cystic fibrosis. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register which comprises references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Date of the most recent search: 04 May 2017.We searched ongoing trials registers (clinicaltrials.gov and the WHO ICTRP). Date of most recent search: 10 August 2017. All randomised and quasi-randomised controlled clinical trials comparing exercise training of any type and a minimum duration of two weeks with conventional care (no training) in people with cystic fibrosis. Two authors independently selected studies for inclusion, assessed methodological quality and extracted data. The quality of the evidence was assessed using the GRADE system. Of the 83 studies identified, 15 studies which included 487 participants, met the inclusion criteria. The numbers in each study ranged from nine up to 72 participants; two studies were in adults, seven were in children and adolescents and six studies included all age ranges. Four studies of hospitalised participants lasted less than one month and 11 studies were outpatient-based, lasting between two months and three years. The studies included participants with a wide range of disease severity and employed differing levels of supervision with a mixture of types of training. There was also wide variation in the quality of the included studies.This systematic review shows very low- to low-quality evidence from both short- and long-term studies that in people

    Male Sickle cell disease (SCD) patients often have moderate to severe hypogonadism resulting in abnormal seminal fluid parameters due to testicular dysfunction. Hydroxyurea (HU), the only drug found to be effective in preventing morbidity and mortality in sickle cell disease patients has been found to further aggravate the testicular dysfunction. This was a prospective study done at a tertiary care hospital over 26 months between September 2011 to October 2013. 100 male sickle cell disease patients of age group 15 to 45 years were recruited in the study. We evaluated seminal fluid indices in all patients and the effect of hydroxyurea on seminal fluid parameters. Hydroxyurea was given at low dose of 10mg/kg/day orally to patients with frequent vaso-occlusive crisis and frequent need of blood transfusion. Seminal fluid analysis was done according to WHO criteria before starting hydroxyurea and every 3 months after initiation of hydroxyurea. Patients with abnormal seminal parameters before hydroxyurea therapy were not given hydroxyurea therapy. Patients with abnormal sperm parameters were subjected for FNAC of testis. In sickle cell disease patients with hydroxyurea therapy, who developed abnormal seminal fluid parameters, hydroxyurea was stopped for 3 months and seminal fluid parameters were re-evaluated. Patients who had recovery of seminal indices after hydroxyurea cessation were restarted with hydroxyurea therapy at low dose. Among Sickle cell disease patients without hydroxyurea therapy, 18% of patients developed oligospermia and 4% developed azoospermia. Among sickle cell disease patients with hydroxyurea therapy, 20% of patients developed oligospermia and 10% developed azoospermia. Seminal fluid parameters reverted back to normal after stoppage of hydroxyurea for 3 months in 73% of patients. Alteration of sperm parameters is seen in a significant number of sickle cell disease patients. Also, alterations of seminal fluid parameters are exacerbated by hydroxyurea

    Semen samples from 100 beef breed bulls were evaluated for sperm morphology (phased contrast microscopy), seminal white blood cells, and the presence of potential reproductive pathogens. Eligibility required visualization of the glans penis throughout semen collection. Based on clinical spermiograms, bulls were grouped into normal, marginal, or unsatisfactory morphology classifications. The 3 experimental groups were similar in age and scrotal circumference and differed significantly in the percentage of primary sperm abnormalities. Most semen samples (94%) contained one or more potential reproductive pathogens (Hemophilus somnus. Mycoplasma bovigenitalium, Arcanobacterium pyogenes and Ureaplasma diversum). No significant relationship could be demonstrated between primary abnormalities and the assigned culture score. Our experimental results suggest that clinicians should interpret clinical semen culture results with great care. No significant relationship could be demonstrated between primary abnormalities and assigned white blood cell (WBC) score, although, only 1% of the samples was scored >5 WBC per high power field. The use of seminal WBC score may be valid adjunct to routine semen evaluation when that threshold is the basis for clinical decisions.

    2011-01-01

    Introduction: we present the case of a 43-year-old male patient who was admitted to the urology service with symptoms of bladder irritation. Workup included ultrasound, cystoscopy, CT and MRI, revealing a seminal vesicle cyst associated with renal agenesis and ectopic ureter insertion. Objective: to demonstrate the relationship between the findings of this case and the embryological development of the urinary tract, using different imaging methods. Materials and methods: clinical case presentation and imaging studies. Conclusion: congenital anomalies of the seminal vesicles may be classified according to their number, position, or maturation, among other things. The most frequent, although rare are cysts and agenesis. With regard to their assessment, magnetic resonance imaging is the technique of choice because of its greater accuracy in demonstrating the nature of the anomaly, and its ability to show associated abnormalities.

    Full Text Available In this study, selected components of seminal plasma in equine semen were evaluated. Levels of enzymes, electrolytes, microelements and some other components were observed. The aim of this study was to fi nd some important differences between the levels of these components and the total sperm motility after freezing and thawing (freezability of the semen. Total of 32 ejaculates from 7 stallions were collected, assessed and prepared in 0,5 ml straws for freezing. After thawing, the sperm motility was analyzed and ejaculates were divided into two groups: “good” freezable and “poor” freezable. The only statistically significant difference between groups of „good“ and „poor“ freezable ejaculates was in the concentration of vitamin E in the seminal plasma. In the group of „good“ freezable ejaculates, the level of vitamin E was significantly lower (p≤0,05 than in the group of “poor” freezable ejaculates.

    Full Text Available The population of anoa, which is an endemic fauna to Indonesia, was getting decrease caused by the illegal hunting and deforestation. Anoa is included in endangered species by IUCN, and Appendix I by CITES. The experiment aimed to characterize the seminal plasma contents and to cryopreserve the anoa semen for artificial insemination application in captivity. The experiment was carried out in Taman Safari Indonesia (Bogor. Semen was collected from 2 anesthetized males (4-10 years by electroejaculation. Seminal plasma gained by centrifugation of ejaculate (3000 rpm, 20 minutes, and then was evaluated the biochemical contents. Other ejaculates were evaluated macroscopically and microscopically, and then extended in Tris and Na-citrate media to a total concentration of 100 billion cells mL-1. Extended semen was stored at 4oC, and evaluated the motility and viability every 12 h. Frozen semen was made in Tris medium added with 5% of glycerol. The seminal plasma of anoa contained total lipid, Na, Ca and Mg higher than the buffalo, but its total protein, K and Cl were lower. Electrophoresis of seminal plasma using by SDS-PAGE method showed 10 bands of proteins (17-148 kDa. The motility and viability of chilled-extended semen in Tris and Na-citrate media were not significantly different (P > 0.05 during 72 h of evaluation. Extended semen in both of media may applicable for AI program for 24-48 h. Post thawing motility of frozen semen was still low, 26.00 ± 9.62%. Therefore, it is necessary to improve each stages of semen processing, so the motility will increased and resulted high pregnancy in AI program.

    Purpose: To quantify the residual geometric uncertainties after on-line corrections with intraprostatic fiducial markers, this study analyzed the deformation of the prostate and, in particular, the seminal vesicles relative to such markers. Patients and Methods: A planning computed tomography (CT) scan and three repeat CT scans were obtained for 21 prostate cancer patients who had had three to four cylindrical gold markers placed. The prostate and whole seminal vesicles (clinical target volume [CTV]) were delineated on each scan at a slice thickness of 1.5 mm. Rigid body transformations (translation and rotation) mapping the markers onto the planning scan positions were obtained. The translation only (T only ) or both translation and rotation were applied to the delineated CTVs. Next, the residue CTV surface displacements were determined using nonrigid registration of the delineated contours. For translation and rotation of the CTV, the residues represented deformation; for T only , the residues stemmed from deformation and rotation. T only represented the residues for most currently applied on-line protocols. The patient and population statistics of the CTV surface displacements were calculated. The intraobserver delineation variation was similarly quantified using repeat delineations for all patients and corrected for. Results: The largest CTV deformations were observed at the anterior and posterior side of the seminal vesicles (population average standard deviation ≤3 mm). Prostate deformation was small (standard deviation ≤1 mm). The increase in these deviations when neglecting rotation (T only ) was small. Conclusion: Although prostate deformation with respect to implanted fiducial markers was small, the corresponding deformation of the seminal vesicles was considerable. Adding marker-based rotational corrections to on-line translation corrections provided a limited reduction in the estimated planning margins

    2014-01-01

    Over the previous 50 years survival of patients with cystic fibrosis has progressively increased. As a result of improvements in health care, increasing numbers of patients with cystic fibrosis are now considering starting families of their own. For the health care professionals who look after these patients, the assessment of the potential risks, and the process of guiding prospective parents through pregnancy and beyond can be both challenging and rewarding. To facilitate appropriate discussions about pregnancy, health care workers must have a detailed understanding of the various important issues that will ultimately need to be considered for any patient with cystic fibrosis considering parenthood. This review will address these issues. In particular, it will outline pregnancy outcomes for mothers with cystic fibrosis, issues that need to be taken into account when planning a pregnancy and the management of pregnancy for mothers with cystic fibrosis or mothers who have undergone organ transplantation as a result of cystic fibrosis.

    Full Text Available Abstract Background Cystic fibrosis (CF is an autosomal recessive disease that is predominantly seen in the Caucasian population and involves multiple organs. Traditionally it has been thought that the kidney is the only organ which does not seem to be generally affected by the disease although the cystic fibrosis transmembrane conductance regulator (CFTR gene is expressed in the kidney. Case presentation We report the case of an 11 year old boy with cystic fibrosis and nephrotic syndrome and review the literature that describes nephrotic syndrome and renal involvement in cystic fibrosis. Conclusion With continued advances in the management of cystic fibrosis and improvement in life expectancy, several unrecognized co-morbidities are expected to emerge. It is important to screen patients for possible co-morbidities. Urine analysis may be helpful in this group of patients and any proteinuria should raise the suspicion of cystic fibrosis-related renal disease.

    Full Text Available Although cystic fibrosis (CF is an irreversible genetic disease, advances in treatment have increased the life expectancy of CF patients. Upper airway involvement, which is mainly due to pathological changes in the paranasal sinuses, is prevalent in CF patients, although many are only mildly symptomatic (with few symptoms. The objective of this literature review was to discuss the pathophysiology and current therapeutic management of chronic rhinosinusitis (CRS in CF patients. The review was based on current evidence, which was classified in accordance with the Oxford Centre for Evidence-Based Medicine criteria. When symptomatic, CRS with nasal polyps can affect quality of life and can lead to pulmonary exacerbations, given that the paranasal sinuses can be colonized with pathogenic bacteria, especially Pseudomonas aeruginosa. Infection with P. aeruginosa plays a crucial role in morbidity and mortality after lung transplantation in CF patients. Although clinical treatment of the upper airways is recommended as initial management, this recommendation is often extrapolated from studies of CRS in the general population. When sinonasal disease is refractory to noninvasive therapy, surgery is indicated. Further studies are needed in order to gain a better understanding of upper airway involvement and improve the management of CRS in CF patients, with the objective of preserving lung function and avoiding unnecessary invasive procedures.

    Full Text Available Aim: The aim of this work was: i to evaluate the prevalence of male partners of subfertile couples being treated with long/short term therapies for non andrological diseases; ii to study their seminal profile for the possible effects of their treatments on spermatogenesis and/or epididymal maturation. Methods: The study group was made up of 723 subjects, aged between 25 and 47 years. Semen analysis was performed according to World Health Organization (WHO guidelines (1999. The Superimposed Image Analysis System (SIAS, which is based on the computerized superimposition of spermatozoa images, was used to assess sperm motility parameters. Results: The prevalence of subjects taking pharmacological treatments was 22.7% (164/723. The prevalence was 3.7% (27/723 for the Short-Term Group and 18.9% (137/723 for the Long-Term Group. The subjects of each group were also subdivided into subgroups according to the treatments being received. Regarding the seminal profile, we did not observe a significant difference between the Long-Term, Short-Term or the Control Group. However, regarding the subgroups, we found a significant decrease in sperm number and progressive motility percentage in the subjects receiving treatment with antihypertensive drugs compared with the other subgroups and the Control Group. Conclusions: In the management of infertile couples, the potential negative impact on seminal parameters of any drugs being taken as Long-Term Therapy should be considered. The pathogenic mechanism needs to be clarified.

    Sibutramine is an inhibitor of norepinephrine and 5-HT reuptake largely used in the management of obesity. Although a fairly safe drug, postmarketing adverse effects of sibutramine were reported including abnormal ejaculation in men. This study investigates the effects of sibutramine on ejaculation and vas deferens and seminal vesicle contractility. Adult male rats received sibutramine (5; 20; or 50 mg kg -1 , ip) and after 60 min were exposed to receptive females for determination of ejaculation parameters. The vasa deferentia and seminal vesicles of untreated rats were mounted in isolated organ baths for recording of isometric contractions and HEK293 cells loaded with fluorescent calcium indicator were used to measure intracellular Ca 2+ transients. Sibutramine 5 and 20 mg kg -1 reduced ejaculation latency whereas 50 mg kg -1 increased ejaculation latency. Sibutramine 3 to 30 μM greatly increased the sensitivity of the seminal vesicle and vas deferens to norepinephrine, but at concentrations higher than 10 μM there were striking depressions of maximal contractions induced by norepinephrine, carbachol and CaCl 2 . In HEK293 cells, sibutramine 10 to 100 μM inhibited intracellular Ca 2+ transients induced by carbachol. Depending on the doses, sibutramine either facilitates or inhibits ejaculation. Apart from its actions in the central nervous system, facilitation of ejaculation may result from augmented sensitivity of smooth muscles to norepinephrine while reductions of intracellular Ca 2+ may be involved in the delayed ejaculation observed with high doses of sibutramine.

    To evaluate protein expression profile and to quantify proteins present in seminal plasma from men with spinal cord injury (SCI) and healthy men without SCI. Experimental study. University hospital. Twelve SCI patients divided into two groups, six who underwent electroejaculation (EEJ) and six who underwent penile vibratory stimulation (PVS); and ten control subjects presenting normal sperm motility and concentration. EEJ and PVS. The seminal plasma protein profile was analyzed by two proteomic strategies: data-independent label-free quantitative proteomics (MS(E)) and two-dimensional sodium dodecyl sulfate-polyacrylamide gel electrophoresis (2D SDS-PAGE). A total of 638 different proteins were identified by MS(E) and 18 by 2D SDS-PAGE followed by tandem mass spectrometry. Interactome analysis showed key reproductive biologic processes-insemination, sperm and oocyte fusion, and acrosome reaction-related to all groups, as were triglyceride stimuli. Processes related to actin and muscle function and to iron oxidation, transportation, and homeostasis were found only in the EEJ and PVS groups; response to hydrogen peroxide and increased immune response was found only in the PVS group. This study was able to demonstrate differential protein expression among control, PVS, and EEJ groups; SCI is responsible for alterations in seminal plasma protein profile leading to a deviation from homeostasis; proteins reported in both PVS and EEJ groups correlate with the pathophysiology of SCI-related infertility.

    Transferrin (Tf) is a major protein of carp (Cyprinus carpio) seminal plasma. Its relationship with milt quality is unknown. In this study, we sought to determine if Tf is polymorphic in carp seminal plasma and if this polymorphism is related to sperm motility characteristics. We screened males of purebred common carp line (Polish line R6) for Tf polymorphism in blood plasma. The majority of Tf genotypes represented only DD and DG variants. We then collected milt from preselected DD and DG genotypes and tested their sperm motility characteristics using computer-aided sperm analysis (CASA). Tf polymorphism in seminal plasma was found to be identical with that of blood. However, the relationships between Tf polymorphism and iron metabolic parameters were different for blood and semen. These data suggest different regulation of Tf in liver and testis. We found substantial differences in sperm motility characteristics between both genotypes. Spermatozoa of DG males were characterized by lower curvilinear velocity (VCL), amplitude of lateral head displacement (ALH), higher linearity (LIN) and straightness (STR) of movement as compared to DD males. No differences were found in other sperm characteristics such as sperm concentration and percentage of sperm motility. Our results suggest that sperm motility parameters are related to Tf polymorphism and therefore this polymorphism may be related to sperm competitive ability.

    N-acetyl-beta-D-glucosaminidase from human seminal plasma has been separated by the cellulose acetate electrophoresis into two components, isoenzyme I and II. The two isoenzymes are readily separated on a DEAE-Sephadex column. Isoenzyme I which has adsorbed to the column, is eluted at 0.1 M NaCl, whereas isoenzyme II has passed through the column. The following enzyme properties have been obtained: 1) Both isoenzymes show the same Km values (0.27 X 10(-3) M) towards sodio-m-cresol-sufonphtaleinyl-N-acetyl-beta-D-glucosaminide . 2) Both isoenzymes show the same pH optima of 5.4. 3) Optimal temperature for isoenzyme I is 50 degrees C, while that for isoenzyme II is 65 degrees C. Isoenzyme II is heat stable, while isoenzyme I is easily denatured by heat. These characteristics of isoenzyme I and II coincide with previous reports of NAG A and B from the spleen and the kidney, respectively. The activity ratio of isoenzyme I and II has been studied for the reproductive tissues. The % ratio of isoenzyme I and II in the epididymal head is 62 and 38, that in the epididymal tail is 42 and 58, and 38:62 in the seminal vesicle, 35:65 in the prostatic gland and 27:73 in the seminal plasma.

  19. Use of alpaca seminal plasma on ovulation rate and embryonic survival

    Full Text Available The South American camelids are a domesticated species adapted to the high Andes, they are considered as a species of induced ovulation. In these species, so that the release of the oocyte occurs, a neuroendocrine interaction and stimulation during intercourse (which have to lasts on average 18 minutes is necessary. In recent years, several studies have demonstrated the presence of an inducing factor for the ovulation found in the seminal plasma of the male that is crucial for ovulation to occurs in camelids. From 1968 researches were initiated to confirm and determine the inductor factor. The works have shown that ovulation in alpacas occurs after intramuscular and intravaginal application of seminal plasma. Recent studies showed the luteotropic effect of this factor, which is evidenced by the increase and retention of circulating concentrations of LH, the rapid change in the vascularization of the pre-ovulatory follicle and corpus luteum development, this contributes to the increase of the embryonic survival rate, due to the stimulus that causes this hormone in the pituitary to release LH, triggering an additional luteotropic effect on the corpus luteum with increased secretion of progesterone. At the field, level the results are not as manifest in relation to the results obtained when the ultrasound monitoring is performed. However, the work done by different research groups confirm the contribution of seminal plasma in increasing fertility rates and embryonic survival in domestic camelids such as alpaca and llama.

    Malignant tumors of the larynx are extremely rare in children and adolescents. Adenoid cystic carcinoma accounts for less than 1% of all malignant tumors in the larynx. We presented a 16-year-old girl with subglottic adenoid cystic carcinoma, whose symptoms of prolonged and exacerbating dyspnea had been attributed to asthma at another medical center. Indirect flexible and rigid laryngoscopy revealed a smooth mass in the subglottic region occupying 80% of the airway passage. The lesion was also confirmed by both CT and MRI. There was no lymphadenopathy in the neck. The patient was successfully treated by surgery and postoperative radiotherapy. Pathological staging was T4N0M0 according to the AJCC, 2003. During six years of follow-up, there was no evidence for local recurrence or regional and distant metastasis.

    A nonerosive form of rheumatoid arthritis (R.A.) was found in 62 patients out of 660 patients with R.A.. These 62 patients exhibit slowly progressive cystic changes in about the same joints in which usually erosions develop in classic R.A.. The E.S.R. is often low, half of the patients remained seronegative and there are 35 males and 27 females in the group. A smaller group of 15 out of these patients could be followed from a stage wherein the radiographs were normal to a stage of extensive cystic changes, over a period of at least 6 years. An attempt is made to delineate this group within the rheumatoid arthritis disease entity. (orig.) [de

  7. Symptomatic unruptured cerebral aneurysms. Features and surgical outcome

    2010-01-01

    Development of less invasive imaging studies, such as magnetic resonance angiography, has increased the chances that unruptured cerebral aneurysms are found. The rupture risk of 'symptomatic' aneurysms is higher than for 'asymptomatic' aneurysms; so 'symptomatic' aneurysms are more often surgically treated. Many reviews examine 'asymptomatic' unruptured cerebral aneurysms, but few evaluate 'symptomatic' aneurysms. The author has treated many patients with symptomatic unruptured cerebral aneurysms and found that improved cranial nerve signs can be expected if the surgical treatment is performed before the symptoms become irreversible; the critical period is approximately 3 months. It is important to suppress the pulsation of the aneurysms compressing the cranial nerves; both a clipping procedure and endovascular coiling are effective. Cranial nerve signs are more commonly the symptoms of unruptured cerebral aneurysms, but large to giant aneurysms can also be the causes of hemiparesis, hydrocephalus, epilepsy, or even cerebral infarction. This review summarizes the features and surgical outcome of symptomatic unruptured cerebral aneurysms. (author)

    Zinc-binding properties were studied in 'prostatic fluid', i.e. in seminal plasma from patients with agenesis of the Wolffian ducts, and in split-ejaculate fractions dominated by seminal vesicular fluid. The effect of seminal fluid, with different zinc-binding properties, on the stability of zinc-dependent sperm chromatin was assessed by exposing sperm to 1% sodium dodecyl sulphate (SDS) for 60 min. Citrate was the only zinc ligand in 'prostatic fluid', as revealed by gel chromatography. Zinc in this fluid enhanced the stability of sperm chromatin. In contrast, the stability of sperm chromatin was decreased in seminal plasma dominated by vesicular fluid. These results are in accordance with the concept that prostatic fluid ensures the appropriate zinc content and stability of sperm chromatin, whereas abundance of vesicular fluid may jeopardize chromatin stability by reducing chromatin zinc content.

    Cystic fibrosis is the most common life-limiting genetic condition in Caucasians and the life-expectancy of those newly diagnosed is increasing. Inspiratory muscle training may be a way of improving the lung function and quality of life of people with cystic fibrosis. Hence there is a need to establish whether this intervention is beneficial. To determine the effect of inspiratory muscle training on health-related quality of life, pulmonary function and exercise tolerance. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials register comprising of references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Date of most recent search: 08 July 2013. Randomised or quasi-randomised clinical controlled trials comparing different inspiratory muscle training regimens with each other or a control in people with cystic fibrosis. Three review authors independently applied the inclusion and exclusion criteria to publications and assessed the quality of the included studies. Fourteen studies were identified. Of these eight studies with 180 participants met the review inclusion criteria. There was wide variation in the quality of the included studies. Data were not published in sufficient detail or with sufficiently similar outcome measures in these studies to perform meta-analyses. We have not found any evidence to suggest that this treatment is either beneficial or not. We would advise that practitioners evaluate on a case-by-case basis whether or not to employ this therapy. We recommend that future studies make more use of health-related quality of life and exercise tolerance measures; and that there is an agreement upon a single standard measure of classifying the clinical status of the participants.

    A mature cystic teratoma presented as an adrenal mass in a 57-yr-old woman. The tumor was found to be predominantly paraadrenal but focally interrupted the adrenal cortex so that an intraadrenal origin could not be ruled out. Similar lesions have been reported extremely rarely and should be considered in the differential diagnosis of hormonally silent adrenal tumors. The findings of rimlike calcification and fatty density on computed tomography may be helpful diagnostically.

    Neuroblastoma is one of the most common malignant tumors of childhood, with 40 % arising in the adrenal glands. Bilateral adrenal involvement from synchronous development or metastatic spread of the tumor is seen in less than 10 % of children with neuroblastoma [1[. Neuroblastoma rarely presents as a cystic suprarenal mass that is difficult to differentiate from adrenal hemorrhage, extralobar sequestration, or dilated upper-pole renal calyces. To our knowledge, bilateral cystic neuroblastoma has not been previously reported. We present a case of bilateral cystic adrenal neuroblastoma to demonstrate the imaging features of this unusual entity, and to expand the differential diagnosis of bilateral cystic suprarenal masses in an infant.

    Cohen, Taylor Sitarik; Prince, Alice

    2013-01-01

    Cystic fibrosis transmembrane conductance regulator (CFTR) functions as a channel that regulates the transport of ions and the movement of water across the epithelial barrier. Mutations in CFTR, which form the basis for the clinical manifestations of cystic fibrosis, affect the epithelial innate immune function in the lung, resulting in exaggerated and ineffective airway inflammation that fails to eradicate pulmonary pathogens. Compounding the effects of excessive neutrophil recruitment, the mutant CFTR channel does not transport antioxidants to counteract neutrophil-associated oxidative stress. Whereas mutant CFTR expression in leukocytes outside of the lung does not markedly impair their function, the expected regulation of inflammation in the airways is clearly deficient in cystic fibrosis. The resulting bacterial infections, which are caused by organisms that have substantial genetic and metabolic flexibility, can resist multiple classes of antibiotics and evade phagocytic clearance. The development of animal models that approximate the human pulmonary phenotypes—airway inflammation and spontaneous infection—may provide the much-needed tools to establish how CFTR regulates mucosal immunity and to test directly the effect of pharmacologic potentiation and correction of mutant CFTR function on bacterial clearance.

    Calcifying epithelial odontogenic tumor (CEOT) is a benign, locally aggressive odontogenic neoplasm characterized by sheets and nests of epithelial cells with deeply eosinophilic or occasionally clear cytoplasm, calcifications, and eosinophilic amorphous material that stains positive for amyloid. Although many cases of CEOT are associated with impacted teeth and occasionally appear radiographically as dentigerous cysts, a true cystic variant has not been previously reported. We report a 15-year-old white male with a large cystic maxillary lesion that filled most of the left maxillary sinus. It deformed the medial wall, the inferior orbital floor, and caused narrowing of the left inferior meatus. Histologically, the cystic lining showed characteristics of CEOT. An intraluminal component that featured histologic characteristics of CEOT was identified during surgery. The lesion was enucleated and the postsurgical course of the patient was uneventful. Because follow-up has been for less than 1 year, a meaningful long-term prognosis cannot be determined at present. However, the patient has not reported any symptoms or signs of recurrence during the follow-up period.

    Purpose: The aim of the study concerning congenital cystic lung malformations was to evaluate prenatal diagnoses postnatally to determine prognostic factors as well as to define optimized perinatal management. Materials and Methods: The study is based on 45 prenatal ultrasound examinations depicting fetal cystic lung lesions. 32 of the mothers had follow-up examinations. 5 pregnancies were terminated due to CCAM and additional malformations. Complete regression of the lesions was seen prenatally in 8 cases and postnatally in 5 children. Results: Surgical intervention due to respiratory insufficiency was necessary in 4 neonates. According to the imaging results, CCAM was present in 4 cases and sequestration in 7 patients. No correlation between the imaging findings and the surgical results was found in 3 children: One child suffered from rhadomyoid dysplasia, and in the case of the second child, a left-sided hernia of the diaphragm and additional sequestration were detected. The third child showed AV malformation. The cystic lesions of the 14 children operated upon were proven histologically. The degree of accuracy in the present study was high. Conclusion: Precise perinatal management is warranted in order to determine according to the clinical relevance surgical intervention and to prevent complications after the first year of life. This is performed during the neonatal period for respiratory insufficient neonates and within the first year of life for clinically stable children. (orig.)

    Full Text Available Background. Nephronophthisis and medullary cystic kidney disease complex refers to the genetic heterogeneous group of inherited tubulointerstital nephritis. Nephronophthisis comprises at last 3 clinical manifestations, has the autosomal recessive pattern of inheritance, appears early in life and is the most frequent inherited kidney disease that causes terminal renal failure in childhood, while medullary cystic kidney disease has the autosomal dominant pattern of inheritance, is less frequent, and terminal renal failure appears later in life. These two forms have similar clinical and morphological findings but extrarenal manifestations, the median ages of occurrence of terminal renal failure, and siblings presence help us distinguish these diseases. Case report. In this article we illustrated the case of a 20- years old patient with the suspicion of having complex nephornophthisis and medullary cystic kidney disease based upon mild renal failure, seen in routinely taken laboratory findings and bilateral cysts in corticomedullary region of the kidneys verified on abdominal ultrasound examination. Conclusion. This disease should rise suspicion in children or adolescents with progressive renal failure, a typical clinical manifestation, blood and urine samples results, bilateral cysts in the corticomedullary region of the kidneys seen during ultrasound examination of the kidneys and family inheritance.

    Full Text Available As espécies S. elegans (Bong. Ruhl. e S. niveus (Kunth. Ruhl. (Eriocaulaceae são conhecidas como sempre-vivas e ocorrem nos campos rupestres da Serra do Cipó - MG. Devido a sua utilização como ornamental, ressalta-se a importância dos dados sobre sua germinação e desenvolvimento pós-seminal. As sementes foram colocadas para germinar em câmara de germinação, em condições controladas, e no ambiente de laboratório no claro e no escuro. Para cada tratamento foram utilizadas 4 repetições com 25 sementes em placas de Petri com papel de filtro umedecido. Os resultados mostraram que as sementes de S. elegans e S. niveus são fotoblásticas positivas. As etapas do desenvolvimento pós-seminal são semelhantes para ambas espécies e, na germinação, observa-se a protrusão do eixo embrionário, de onde se desenvolvem primeiramente as folhas e posteriormente as raízes adventícias. O opérculo da semente fica aderido à testa e a raiz primária se degenera ainda no eixo embrionário.The species S. elegans (Bong. Ruhl. and S. niveus (Kunth. Ruhl. (Eriocaulaceae are known in Brazil as star flowers and they grow in the rupestrian fields of Serra do Cipó - MG. They are used for ornamental purposes so data on their germination and postseminal development are important. In this study the seeds were germinated in growth chamber under controled conditions and in the laboratory under light and dark conditions. For each treatment four repetitions of 25 seeds on Petri plates with humid filter paper were used. The results show that the seeds of S. elegans and S. niveus are positive photoblastic. The post-seminal development stages are the same for both species and during the germination period the undifferentiated axis of the embryo becomes apparent. The observation of the development of this axis shows that the growth of the leaves occurs first than that of the adventitious root. The seed operculum adheres to the testa and the primary root

    There is a paucity of data regarding the association between occupational radiation exposure and risk to human fertility. Recently, we provided the first evidence on altered sperm functional characteristics, DNA damage and hypermethylation in radiation health workers. However, there is no report elucidating the association between seminal plasma antioxidants and sperm chromatin integrity in occupationally exposed subjects. Here, we assessed the seminal plasma antioxidants and lipid peroxidation level in 83 men who were occupationally exposed to ionizing radiation and then correlated with the sperm chromatin integrity. Flow cytometry based sperm chromatin integrity assay revealed a significant decline in αt value in the exposed group in comparison to the non-exposed group (P<0.0001). Similarly, both total and reduced glutathione levels and total antioxidant capacity in the seminal plasma were significantly higher in exposed group than the non-exposed group (P<0.01, 0.001 and 0.0001, respectively). However, superoxide dismutase level and malondialdehyde level, which is an indicator of lipid peroxidation in the seminal plasma, did not differ significantly between two groups. The total antioxidant capacity (TAC) and GSH level exhibited a positive correlation with sperm DNA integrity in exposed subjects. To conclude, this study distinctly shows that altered sperm chromatin integrity in radiation health workers is associated with increase in seminal plasma antioxidant level. Further, the increased seminal plasma GSH and TAC could be an adaptive measure to tackle the oxidative stress to protect genetic and functional sperm deformities in radiation health workers. - Highlights: • Seminal plasma antioxidants were measured in men occupationally exposed to radiation. • Sperm chromatin integrity was significantly affected in the exposed group. • Glutathione and total antioxidant capacity was significantly higher in exposed group. • Sperm DNA damage in exposed subjects

    Antibiotic treatment for pulmonary symptoms in preschool children with cystic fibrosis (CF) varies among clinicians. The lung clearance index (LCI) is sensitive to early CF lung disease, but its utility to monitor pulmonary exacerbations in young children has not been assessed. We aim to (1) understand how LCI changes during lower respiratory tract symptoms relative to a recent clinically stable measurement, (2) determine whether LCI can identify antibiotic treatment response and (3) compare LCI changes to changes in spirometric indices. LCI and spirometry were measured at quarterly clinic visits over a 12-month period in preschool children with CF. Symptomatic visits were identified and classified as treated or untreated. Treatment response was estimated using propensity score matching methods. 104 symptomatic visits were identified in 78 participants. LCI increased from baseline in both treated (mean relative change +23.8% (95% CI 16.2 to 31.4)) and untreated symptomatic visits (mean relative change +11.2% (95% CI 2.4 to 19.9)). A significant antibiotic treatment effect was observed when LCI was used as the outcome measure (average treatment effect -15.5% (95% CI -25.4 to -5.6)) but not for z-score FEV 1 . LCI significantly deteriorated with pulmonary symptoms relative to baseline and improved with antibiotic treatment. These data suggest that LCI may have a role in the routine clinical care of preschool children with CF. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    The sinonasal involvement is one of the most common manifestations in cystic fibrosis. Data show a high incidence of chronic rhino sinusitis in these patients. Although it has been found radiographic opacification of the sinus in more than 90% of cases, few are symptomatic. So that, it is difficult to recognize nasossinusal disease in patients with cystic fibrosis. Questionnaire, nasal endoscopy and CT-scan are very important methods in this approach. Aim: to evaluate the diagnosis of chronic rhino sinusitis in patients with cystic fibrosis by anamnesis, nasal endoscopy and CT-scan and compare those results.Study Design: Clinical prospective. Material and method: evaluation of 34 patients - older than 6 years and with a confirmed diagnoses of cystic fibrosis - by anamnesis (questionnaire), nasal endoscopy (score Lund-Kennedy) and CT-scan (score Lund-Mackay). Results: chronic rhino sinusitis was confirmed in: 20,58% of cases by the questionnaire, 73,52% of the cases by the nasal endoscopy and in 93,54% of the cases by the CT-scan. The results showed significant differences. The correlation between nasal endoscopy score (Lund-Kennedy score) and CT-scan score (Lund-Mackay score) was statistically significant. Conclusion: the diagnosis of chronic rhino sinusitis was statistically different between the three methods. It was higher in imaging analysis and lower in questionnaire. The nasal endoscopy is an excellent method to evaluate nasossinusal disease in cystic fibrosis. (author)

    Colonic diverticulosis is a common condition in Western industrialized countries occurring in up to 65% of people over the age of 60 years. Only a minority of these subjects (about 10-25%) experience symptoms, fulfilling Rome III Diagnostic Criteria for irritable bowel syndrome (IBS) diagnosis (IBS-like symptoms) in 10% to 66% of cases. Symptomatic uncomplicated diverticular disease (SUDD) is a syndrome characterized by recurrent abdominal symptoms attributed to diverticula in the absence of macroscopically evident alterations other than the presence of diverticula. Due to the different peak of incidence, the overlap between SUDD and IBS is predominantly present in middle-aged or older patients. In these cases, it is very complex to establish if the symptoms are related to the presence of diverticula or due to an overlapping IBS. In fact, the link between gastrointestinal symptoms and diverticula is unclear, and the mechanism by which diverticula may induce the development of IBS-like symptoms remains to be elucidated. Currently, the etiology and pathophysiology of SUDD, particularly when IBS-like symptoms are present, are not completely understood, and thus these two entities remain a diagnostic challenge not only for the general practitioner but also for the gastroenterologist. Although many issues remain open and unresolved, some minimize the importance of a distinction of these two entities as dietary and pharmacological management may be largely overlapping.

    Acquired urachal anomalies are a rare pathology. Gold-standard treatment for this clinical situation remains the resection of the urachus in its entire tract with or without partial resection of the bladder. Our aim is to up-date authors's experience in the minimally invasive surgical treatment of acquired urachal disease. From 2001 to 2007, 14 patients were operated for acquired urachal disease at our institution. A three portal technique previously described by the authors was employed. The diagnosis of acquired uracal disease was confirmed in all cases and the resection of the urachus in its entire tract performed in cephalocaudal direction onto the bladder. Operative and demographic data was prospectively collected and analysis retrospectively performed. Mean operative time was 63 minutes (45,110), minimal blood loss, and no conversions to open surgery or perioperative complications were verified. The majority of the patients were discharged in the first 24 hours. At a follow-up of 22 months no recurrences of urachal pathology recurrences have been verified. Laparoscopy plays a significant role in the management of symptomatic urachus anomalies. It allows objective confirmation of clinical diagnosis and adequate resection of the urachus in a safe and efficient fashion, while providing the well-known advantages of minimally acces surgery. Preoperative evaluation work-up has minimal impact of therapeutical decision.

    Acute symptomatic hyponatremia after thiazide diuretic initiation is a medical emergency. Here we describe the case of a flight attendant who developed acute hyponatremia during a flight and the potential risk factors for developing this condition. A 57-year-old flight attendant with history of essential hypertension was recently started on a thiazide diuretic. As she did routinely when working, she increased her water intake during a flight from London to Mexico City. She complained of nausea and headache during the flight. Upon arrival, she developed severe disorientation and presented to the hospital emergency room (ER) with a Glasgow scale of 12, hypoxia, and a generalized tonic clonic seizure. Her laboratory results on arrival were consistent with severe hyponatremia (serum Na 116 mEql/L) and severe cerebral edema by CT scan. She was treated with hypertonic saline, with complete resolution of the neurologic symptoms. We describe high water intake and hypoxia related to decreased partial pressure of oxygen in the cabin as the two main risk factors for thiazide-induced acute hyponatremia in this case.

    This study reports the first case of symptomatic placental transfer of cryoglobulins and discusses the potential pathogenic processes and the basic guidelines for neonatal management. A 32-y-old woman was affected by essential type I cryoglobulinaemia and displayed the cold-triggered cutaneous symptoms of the disease due to a monoclonal immunoglobulin G (IgG) cryoglobulin. She gave birth to healthy dizygotic twins who were placed in incubators immediately after birth and did not show any cutaneous or visceral lesion in the first 2 d. Cyanotic macules appeared on the hand and foot of one of the newborns when they were removed from the incubators. The same monoclonal IgG-lambda cryoglobulin was identified in the two newborns' cord blood and in the mother's serum. The skin lesions disappeared within 1 wk as both twins were transiently replaced in incubators. No recurrence of skin lesions was observed even at room temperature and, 6 mo later, both twins were healthy and their clinical examination was normal. To the authors' knowledge, this is the first report of placental transfer of cryoglobulins and the first description of any neonatal effect. Neonates born to mothers suffering from IgG cryoglobulinaemia should be protected against cold to avoid precipitation of the pathogenic cryoglobulins, until spontaneous resolution.

    Poor nutrition occurs frequently in people with cystic fibrosis and is associated with other adverse outcomes. Oral calorie supplements are used to increase total daily calorie intake and improve weight gain. However, they are expensive and there are concerns they may reduce the amount of food eaten and not improve overall energy intake. This is an update of a previously published review. To establish whether in people with cystic fibrosis, oral calorie supplements: increase daily calorie intake; and improve overall nutritional intake, nutritional indices, lung function, survival and quality of life. To assess adverse effects associated with using these supplements. We searched the Cochrane Cystic Fibrosis Trials Register comprising references from comprehensive electronic database searches, handsearches of relevant journals and abstract books of conference proceedings. We contacted companies marketing oral calorie supplements.Last search: 18 October 2016. Randomised or quasi-randomised controlled trials comparing use of oral calorie supplements for at least one month to increase calorie intake with no specific intervention or additional nutritional advice in people with cystic fibrosis. We independently selected the included trials, assessed risk of bias and extracted data. We contacted the authors of included trials and obtained additional information for two trials. We identified 21 trials and included three, reporting results from 131 participants lasting between three months and one year. Two trials compared supplements to additional nutritional advice and one to no intervention. Two of the included trials recruited only children. In one trial the risk of bias was low across all domains, in a second trial the risk of bias was largely unclear and in the third mainly low. Blinding of participants was unclear in two of the trials. Also, in one trial the clinical condition of groups appeared to be unevenly balanced at baseline and in another trial there were

    Previous small studies have shown either no difference or a lower risk of symptomatic gallstone disease in vegetarians than in non-vegetarians. This study examined the incidence of symptomatic gallstone disease in a cohort of British vegetarians and non-vegetarians, and investigated the associations between nutrient intake and risk of symptomatic gallstone disease. The data were analysed from 49 652 adults enroled in the European Prospective Investigation into Cancer and Nutrition (EPIC)-Oxford study, one-third of whom were vegetarian. The linked databases of hospital records were used to identify incident cases. Risk by diet group was estimated using Cox proportional hazards models. Further analysis quantified risk by intakes of selected macronutrients. There were 1182 cases of symptomatic gallstone disease during 687 822 person-years of follow-up (mean=13.85 years). There was a large significant association between increasing body mass index (BMI) and risk of developing symptomatic gallstone disease (overall trend Pvegetarians had a moderately increased risk compared with non-vegetarians (HR: 1.22; 95% CI: 1.06-1.41; P=0.006). Although starch consumption was positively associated with gallstones risk (P=0.002 for trend), it did not explain the increased risk in vegetarians. There is a highly significant association of increased BMI with risk of symptomatic gallstone disease. After adjusting for BMI, there is a small but statistically significant positive association between vegetarian diet and symptomatic gallstone disease.

    Seizures are believed to be common presenting symptoms in neonates and children with spontaneous intracerebral hemorrhage (ICH). However, few data are available on the epidemiology of acute symptomatic seizures or the risk for later epilepsy. To define the incidence of and explore risk factors for seizures and epilepsy in children with spontaneous ICH. Our a priori hypotheses were that younger age at presentation, cortical involvement of ICH, acute symptomatic seizures after presentation, ICH due to vascular malformation, and elevated intracranial pressure requiring urgent intervention would predict remote symptomatic seizures and epilepsy. Prospective cohort study conducted between March 1, 2007, and January 1, 2012. Three tertiary care pediatric hospitals. Seventy-three pediatric subjects with spontaneous ICH including 20 perinatal (≥37 weeks' gestation to 28 days) and 53 childhood subjects (>28 days to Acute symptomatic seizures (clinically evident and electrographic-only seizures within 7 days), remote symptomatic seizures, and epilepsy. Acute symptomatic seizures occurred in 35 subjects (48%). Acute symptomatic seizures as a presenting symptom of ICH occurred in 12 perinatal (60%) and 19 childhood (36%) subjects (P = .07). Acute symptomatic seizures after presentation occurred in 7 children. Electrographic-only seizures were present in 9 of 32 subjects (28%) with continuous electroencephalogram monitoring. One-year and 2-year remote symptomatic seizure-free survival rates were 82% (95% CI, 68-90) and 67% (95% CI, 46-82), respectively. One-year and 2-year epilepsy-free survival rates were 96% (95% CI, 83-99) and 87% (95% CI, 65-95), respectively. Elevated intracranial pressure requiring acute intervention was a risk factor for seizures after presentation (P = .01; Fisher exact test), remote symptomatic seizures, and epilepsy (P = .03, and P = .04, respectively; log-rank test). Presenting seizures are common in perinatal and childhood ICH. Continuous

    Cystic fibrosis (CF) is a genetic disorder with multiorgan effects. In a subgroup with pancreatic insufficiency malabsorption of the fat soluble vitamins (A, D, E, K) may occur. Vitamin D is involved in calcium homeostasis and bone mineralisation and may have extraskeletal effects. This review examines the evidence for vitamin D supplementation in cystic fibrosis. To assess the effects of vitamin D supplementation on the frequency of vitamin D deficiency, respiratory outcomes and vitamin D toxicity in the cystic fibrosis population. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register comprising references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Date of the most recent search: 08 July 2013. Randomised and quasi-randomised controlled studies of vitamin D supplementation compared to placebo in the cystic fibrosis population regardless of exocrine pancreatic function. Both authors independently assessed the risk of bias of each included study and extracted outcome data (from published study information) for assessment of bone mineralization, growth and nutritional status, frequency of vitamin D deficiency, respiratory status, quality of life and adverse events. Six studies (239 participants) are included, although only three studies provided data from 69 adults and children with cystic fibrosis for analysis. One study compared a single high dose of vitamin D (250,000 IU) to placebo at the time of hospital admission with a respiratory exacerbation in 30 pancreatic insufficient adults with cystic fibrosis. The second study compared supplemental 800 international units (IU) vitamin D and placebo for 12 months in 30 osteopenic pancreatic insufficient adults; both groups continued 900 IU vitamin D daily. The third study compared supplemental 1 g calcium alone, 1600 IU vitamin D alone, 1600 IU vitamin D and 1 g calcium and placebo in a double

    Full Text Available Mucinous cystic neoplasms (MCNs make up a morphologic family of similar appearing tumors arising in the ovary and various extraovarian organs such as pancreas, hepatobiliary tract and mesentery. MCNs of the pancreas occur almost exclusively in women. Here, we report a rare case of MCN in a male patient. A 39-year-old man was admitted to our hospital with the chief complaint of back pain. Abdominal computed tomography revealed a multilocular cyctic mass 6.3 cm in diameter in the pancreatic tail. In addition, the outer wall and septae with calcification were demonstrated in the cystic lesion. On magnetic resonance imaging , the cystic fluid had low intensity on T1-weighted imaging and high intensity on T2-weighted imaging. Endoscopic retrograde cholangio-pancreatography (ERCP showed neither communication between the cystic lesion and the main pancreatic duct nor encasement of the main pancreatic duct. Endoscopic ultrasonography revealed neither solid component nor thickness of the septae in the cystic lesion. Consequently, we performed distal pancreatectomy with splenectomy under the diagnosis of cystic neoplasia of the pancreas. Histopathologically, the cystic lesion showed two distinct component: an inner epithelial layer and an outer densely cellular ovarian-type stromal layer. Based on these findings, the cystic lesion was diagnosed as MCN.

    The mechanisms involved in bleeding in cases of placenta previa (PP) and the effect on pregnancy outcome is unclear. We aimed to compare pregnancy outcome and placental histopathology in pregnancies complicated with symptomatic (bleeding) vs. non-symptomatic PP, and to study the effects of the co-existence of histopathological retro-placental hemorrhage (RPH) in cases of symptomatic PP on neonatal and maternal outcomes. Labor and maternal characteristics, neonatal outcome and placental histopathology lesions of pregnancies with PP, delivered between 24 and 42weeks, during 2009-2015, were reviewed. Results were compared between PP who had elective cesarean delivery (CD) (previa group) and PP with bleeding necessitating emergent CD (symptomatic previa group). Placental lesions were classified to lesions consistent with maternal malperfusion or fetal thrombo-occlusive disease (vascular and villous changes), and inflammatory lesions. Compared to the previa group (n=63), the symptomatic previa group (n=74) was characterized by older patients (pPlacentas within the symptomatic previa group were smaller, with higher rates of weightplacenta previa is associated with increased placental malperfusion lesions suggesting an association of maternal malperfusion with abnormal placental separation. The coexisting finding of RPH with symptomatic placenta previa can be seen as a marker for more extensive/severe placental separation, hence the association with maternal transfusion requirements and poorer fetal outcome.

    Roots play a key role in water acquisition and are a significant component of plant adaptation to different environmental conditions. Although maize (Zea mays L.) is one of the most important crops worldwide, there is limited information on the function of different root segments and types in extracting water from soils. Aim of this study was to investigate the location of root water uptake in mature maize. We used neutron radiography to image the spatial distribution of maize roots and trace the transport of injected deuterated water (D2O) in soil and roots. Maize plants were grown in aluminum containers filled with a sandy soil that was kept homogeneously wet throughout the experiment. When the plants were five weeks-old, we injected D2O into selected soil regions. The transport of D2O was simulated using a diffusion-convection numerical model. By fitting the observed D2O transport we quantified the diffusion coefficient and the water uptake of the different root segments. The model was initially developed and tested with two weeks-old maize (Ahmed et. al. 2015), for which we found that water was mainly taken up by lateral roots and the water uptake of the seminal roots was negligible. Here, we used this method to measure root water uptake in a mature maize root system. The root architecture of five weeks-old maize consisted of primary and seminal roots with long laterals and crown (nodal) roots that emerged from the above ground part of the plant two weeks after planting. The crown roots were thicker than the seminal roots and had fewer and shorter laterals. Surprisingly, we found that the water was mainly taken up by the crown roots and their laterals, while the lateral roots of seminal roots, which were the main location of water uptake of younger plants, stopped to take up water. Interestingly, we also found that in contrast to the seminal roots, the crown roots were able to take up water also from their distal segments. We conclude that for the two weeks

    Human seminal plasma contains a variety of macro and trace elements including magnesium (Mg), copper (Cu), zinc (Zn), and iron (Fe) that have essential roles in normal functioning of semen and its quality. The imbalance of these elements has been reported in several pathologic and male infertility disorders. Therefore, this study aimed to determine the levels of these elements in seminal plasma samples, their relationships with each other and their impact on sperm motility. Overall, 192 males (96 normospermic and 96 asthenospermic males) were enrolled in the study. Semen samples were collected by masturbation and computer-assisted/aided semen analysis of sperm motility was performed. The samples were centrifuged and seminal levels of Mg, Cu, Zn and Fe were measured using atomic absorption spectroscopy. The levels of Zn did not differ between the two groups, while the levels of Mg, Cu, and Fe were significantly higher in normospermic males. Fe showed a positive correlation with Mg and Cu in asthenospermic group. However, a negative relationship was found between Mg and Fe levels and between Mg and sperm concentration in the normospermic group. Fe levels were higher in the normospermic group compared to the asthenospermic group. Nevertheless, increased Fe levels caused a decrease in most of sperm motility fractions. Elements play major roles in male fertility and directly affect sperm quality. According to the results of this study, the levels of Zn do not affect the sperm quality and motility, while Fe, Cu and Mg are decreased in males with sperm motility problems. Nevertheless, Fe levels can adversely affect sperm motility in normospermic men.

    This study proposed lipid fingerprinting of human seminal plasma by mass spectrometry as an analytical method to differentiate biological conditions. For this purpose, we chose infertile men as a model to study specific conditions, namely: high and low seminal plasma lipid peroxidation levels (sub-study 1.1), high and low sperm nuclear DNA fragmentation (sub-study 1.2), and intervention status: before and after subinguinal microsurgical varicocelectomy (study 2). Study 1 included 133 patients, of which 113 were utilized for sub-study 1.1 and 89 for sub-study 1.2. Study 2 included 17 adult men submitted to subinguinal varicocelectomy, before and 90 days after varicocelectomy. Lipids were extracted from seminal plasma and submitted to Matrix-Assisted Laser Desorption Ionization Quadrupole-Time-of-Flight Mass Spectrometry in the positive ionization mode. Spectra were processed using Waters(®) MassLynx, and MetaboAnalyst online software was used for statistical analyses. For sub-studies 1.1 and 1.2, and study 2, univariate analysis revealed 8, 87 and 34 significant ions, respectively. Multivariate analysis was performed through PCA and PLS-DA. PCA generated 56, 32 and 34 components respectively for each study and these were submitted to logistic regression. A ROC curve was plotted and the area under the curve was equal to 97.4, 92.5 and 96.5%. PLS-DA generated a list of 19, 24 and 23 VIP ions for sub-studies 1.1 and 1.2, and study 2, respectively. Therefore, this study established the lipid profile and comparison of patterns altered in response to specific biological conditions.

    Full Text Available Cervical cancer is one of the leading causes of cancer-related death in women in sub-Saharan Africa. Extensive evidence has shown that cervical cancer and its precursor lesions are caused by Human papillomavirus (HPV infection. Although the vast majority of HPV infections are naturally resolved, failure to eradicate infected cells has been shown to promote viral persistence and tumorigenesis. Furthermore, following neoplastic transformation, exposure of cervical epithelial cells to inflammatory mediators either directly or via the systemic circulation may enhance progression of the disease. It is well recognised that seminal plasma contains an abundance of inflammatory mediators, which are identified as regulators of tumour growth. Here we investigated the role of seminal plasma in regulating neoplastic cervical epithelial cell growth and tumorigenesis. Using HeLa cervical adenocarcinoma cells, we found that seminal plasma (SP induced the expression of the inflammatory enzymes, prostaglandin endoperoxide synthase (PTGS1 and PTGS2, cytokines interleukin (IL -6, and -11 and vascular endothelial growth factor-A (VEGF-A. To investigate the role of SP on tumour cell growth in vivo, we xenografted HeLa cells subcutaneously into the dorsal flank of nude mice. Intra-peritoneal administration of SP rapidly and significantly enhanced the tumour growth rate and size of HeLa cell xenografts in nude mice. As observed in vitro, we found that SP induced expression of inflammatory PTGS enzymes, cytokines and VEGF-A in vivo. Furthermore we found that SP enhances blood vessel size in HeLa cell xenografts. Finally we show that SP-induced cytokine production, VEGF-A expression and cell proliferation are mediated via the induction of the inflammatory PTGS pathway.

    Cystic fibrosis (CF) is an incurable, chronic disease, which causes severe damages to respiratory and digestive tracts. It is the most common genetically inherited disease among caucasians. This disease is caused by defects in CF genes, the so-called mutations in cystic fibrosis transmembrane conductance regulator (CFTR) gene population. At present over 100,000 people suffer from this disease worldwide. The purpose of this review study is to describe the pathophysiology of CF and provide the latest information on its diagnosis and treatment therapies with respect to the improvement of patient's quality of life and emphasis on targeted specialized care. The methodological approaches include a method of literature review of available sources exploring the issue of cystic fibrosis both from a global and specific perspective point of view. A search was performed in the databases PubMed, MEDLINE, Web of Science, Scopus, Springer and ScienceDirect. Furthermore, other sources cited in the analyzed studies were also examined. On the basis of evaluation of these literature sources, the research issue was explored. The main benefits (e.g., specialized centres for the treatment of CF exist or a new breakthrough in the gene therapy of CF has been made) and limitations (e.g., comorbidity of CF, lifelong and costly treatment, or adverse impact on patient's and caregiver's quality of life) in the treatment of narcolepsy are highlighted. CF requires an integrated treatment approach in specialized CF centers, involving various factors contributing to a better patient's state of health in the form of relevant and well-balanced non-pharmacological and pharmacological therapies. In addition, further large scale clinical trials are needed in order to develop compounds that are aimed at the most common classes of CFTR.

    Cystic fibrosis is a genetic disorder which can lead to multiorgan dysfunction. Malabsorption of fat and fat-soluble vitamins (A, D, E, K) may occur and can cause subclinical deficiencies of some of these vitamins. Vitamin K is known to play an important role in both blood coagulation and bone formation. Supplementation with vitamin K appears to be one way of addressing the deficiency, but there is very limited agreement on the appropriate dose and frequency of use of these supplements. This is an updated version of the review. To assess the effects of vitamin K supplementation in people with cystic fibrosis and to determine the optimal dose and route of administration of vitamin K for both routine and therapeutic use. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Trials Register comprising references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Most recent search: 30 January 2017. Randomised and quasi-randomised controlled trials of all preparations of vitamin K used as a supplement compared to either no supplementation (or placebo) at any dose or route and for any duration, in children or adults diagnosed with cystic fibrosis (by sweat test or genetic testing). Two authors independently screened papers, extracted trial details and assessed their risk of bias. Two trials (total of 32 participants) each lasting one month were included in the review and were assessed as having a moderate risk of bias. One was a dose-ranging parallel group trial in children (aged 8 to 18 years); and the other (with an older cohort) had a cross-over design comparing supplements to no treatment, but no separate data were reported for the first intervention period. Neither of the trials addressed any of the primary outcomes (coagulation, bone formation and quality of life). Both trials reported the restoration of serum vitamin K and undercarboxylated osteocalcin

    Symptomatic uncomplicated diverticular disease is considered to be a discreet clinical entity distinct from irritable bowel syndrome (IBS), but population-based data are unavailable. We aimed to investigate the prevalence and location of diverticulosis in the general population, and its association with colonic symptoms and mental health. We propose that individuals with diverticulosis would report more constipation and IBS. We performed a population-based study of randomly selected adults born in Sweden (age, 18-70 y; 57.2% women); 745 received a gastroenterology consultation, completed validated abdominal symptom and mental health questionnaires, and were examined by colonoscopy. Logistic regression was used to calculate the associations between diverticulosis and age, sex, gastrointestinal symptoms, anxiety, depression, and self-rated health. Among the 742 participants (54.6% women), 130 (17.5%) had diverticulosis. Age was the strongest predictor of diverticulosis (P diverticulosis was rare in participants younger than 40 years (0.7%). All participants with diverticulosis had sigmoid involvement. Participants with diverticulosis were more likely to report loose stools (odds ratio [OR], 1.88; 95% confidence interval [CI], 1.20-2.96), urgency (OR, 1.64; 95% CI, 1.02-2.63), passing mucus (OR, 2.26; 95% CI, 1.08-4.72), and a high stool frequency (OR, 2.02; 95% CI, 1.11-3.65). Diverticulosis was associated with abdominal pain (OR, 2.10; 95% CI, 1.01-4.36; P = .047) and diarrhea-predominant IBS (OR, 9.55; 95% CI, 1.08-84.08; P = .04) in participants older than 60 years. The presence of anxiety and depression and self-rated health were similar in participants with and without diverticulosis. The prevalence of diverticulosis is age-dependent. Diverticulosis is associated with diarrhea in subjects across all age ranges. In subjects older than age 60, diverticulosis is associated with abdominal pain and diarrhea-predominant IBS.

    Sperms induced IgE production by seminal B cells from patients with atopic eczema via interaction of B cells with galectin-3 on sperms. We studied the effect of viewing a humorous film on IgE production by seminal B cells cultured with sperms. Twenty-four male patients with atopic eczema viewed a humorous film (Modern Times, featuring Charlie Chaplin). Just before and immediately after viewing, semen was collected, and seminal B cells and sperms were purified. Seminal B cells were cultured with sperms and IgE production was measured, while expression of galectin-3 on sperms was assessed. After viewing the humorous film, IgE production by B cells cultured with sperms was significantly decreased. Moreover, expression of galectin-3 on sperms was reduced. Viewing a humorous film reduced galectin-3 expression on sperms, which in turn decreased IgE production by seminal B cells cultured with sperms. These results indicate that viewing a humorous film may be helpful for the study and treatment of local IgE production and allergy in the reproductive tract.

    The ejaculate of diverse primate species consists of two portions, liquid and solid; the latter, known as the seminal coagulum, is thought to sequester large numbers of sperm. In the black-handed spider monkey (Ateles geoffroyi), ejaculates collected by electroejaculation did not always contain seminal coagulum. The objective of the present study was to determine seasonal emission of seminal coagulum and in vivo sperm dynamics in the black-handed spider monkey. Seminal coagulum emission was related to season; it was more frequent in the dry season, coincident with maximal female fertility. Sperm concentration was higher (P = 0.02) in the dry season (dry vs. rainy season: 137.9 +/- 15.7 sperm/mL vs. 82.56 +/- 14.7 x1 0(6) sperm/mL; mean +/- S.E.M.) but also in ejaculates (collected during the rainy season) that had seminal coagulum (coagulum vs. no coagulum: 140.0 +/- 29.3 sperm/mL vs. 31.2+/-0.1 x 10(6) sperm/mL, P<0.001). In semen samples collected from the uterus after AI, the percentage of linearly motile sperm was higher during the dry season (dry vs. rainy: 9.1+/-2.1% vs. 5.9+/-2.5%), as well as whenever coagulum was present (coagulum vs. no coagulum: 13.0+/-3.2% vs. 2.0+/-0.9%, P<0.001).

  15. Terminal Mannose Residues in Seminal Plasma Glycoproteins of Infertile Men Compared to Fertile Donors

    Full Text Available The impact of seminal plasma components on the fertilization outcomes in humans is still under question. The increasing number of couples facing problems with conception raises the need for predictive biomarkers. Detailed understanding of the molecular mechanisms accompanying fertilization remains another challenge. Carbohydrate–protein recognition may be of key importance in this complex field. In this study, we analyzed the unique glycosylation pattern of seminal plasma proteins, the display of high-mannose and hybrid-type oligosaccharides, by means of their reactivity with mannose-specific Galanthus nivalis lectin. Normozoospermic infertile subjects presented decreased amounts of lectin-reactive glycoepitopes compared to fertile donors and infertile patients with abnormal semen parameters. Glycoproteins containing unveiled mannose were isolated in affinity chromatography, and 17 glycoproteins were identified in liquid chromatography-tandem mass spectrometry with electrospray ionization. The N-glycome of the isolated glycoproteins was examined in matrix-assisted laser desorption ionization mass spectrometry. Eleven out of 27 identified oligosaccharides expressed terminal mannose residues, responsible for lectin binding. We suggest that lowered content of high-mannose and hybrid type glycans in normozoospermic infertile patients may be associated with impaired sperm protection from preterm capacitation and should be considered in the search for new infertility markers.

    Human seminal plasma (HSP) No. 7 antigen was purified by immunoaffinity chromatography on bound 1C4 monoclonal antibody (Moab) (Shigeta et al., 1980b). The pooled HSP protein was applied to a CNBr-activated Sepharose 4B column of bound 1C4 Moab gamma globulin and the antibody bound fraction (fr) eluted was further purified by rechromatography in the same way. The purified antigen in the antibody bound fr obtained by rechromatography gave a single band on SDS-PAGE in a position corresponding to a molecular weight of 15,000 daltons. This preparation was 196.2 times more effective than the original HSP protein in neutralizing the sperm immobilizing activity of 1C4 Moab. The purified HSP No. 7 antigen contained iron, but was different from lactoferrin and transferrin. It did not show any enzymatic activities, such as those of acid phosphatase, LDH or trypsin inhibitor, and shared antigenicity with human milk protein. It was present in seminal plasma as a molecule with a higher molecular weight but seemed to be cleaved to a monomer of 15,000 daltons during purification procedures. This antigen is present on spermatozoa as sperm-coating antigen and the corresponding antibody can immobilize spermatozoa with complement.

    Sperm proteomes have emerged for several species; however, the extent of species similarity is unknown. Sheep are an important agricultural species for which a comprehensive sperm proteome has not been produced. In addition, potential proteomic factors from seminal plasma that may contribute to improved fertility after cervical insemination are yet to be explored. Here we use liquid chromatography-tandem mass spectrometry to investigate the proteome of ejaculated ram spermatozoa, with quantitative comparison to epididymal spermatozoa. We also present a comparison to published proteomes of five other species. We identified 685 proteins in ejaculated ram spermatozoa, with the most abundant proteins involved in metabolic pathways. Only 5% of ram sperm proteins were not detected in other species, which suggest highly conserved structures and pathways. Of the proteins present in both epididymal and ejaculated ram spermatozoa, 7% were more abundant in ejaculated spermatozoa. Only two membrane-bound proteins were detected solely in ejaculated sperm lysates: liver enriched gene 1 (LEG1/C6orf58) and epidermal growth factor-like repeats and discoidin I-like domains 3 (EDIL3). This is the first evidence that despite its relatively complex proteomic composition, seminal plasma exposure leads to few novel proteins binding tightly to the ram sperm plasma membrane.

    To understand sperm plug dissolution and spermatophore dehiscence in Portunidae, histological and ultrastructural changes in the seminal receptacle (SR) of Arenaeus cribrarius were investigated during ovarian development. In juvenile females the SR was filled with acid polysaccharides and the dorsal epithelium was stratified. Mated females with rudimentary ovaries showed a large SR filled by a glycoprotein sperm plug. This plug was present until the developing-ovary stage, when spermatophore dehiscence and intense holocrine secretions in the dorsal dense layer occurred. The plug was absent after the intermediate stage, and the SR became flaccid. The secretion produced moved the spermatophores into the ventral region. The modified dorsal epithelium in the transition between the dorsal and ventral regions released acid polysaccharides, which were found among the sperm, by exocytosis. The morphological changes of the SR in A. cribrarius, including the presence of the sperm plug, followed the macroscopic pattern observed in other members of Portunidae, such as blue crabs. However, in this species dissolution of the sperm plug was synchronized with ovarian development and occurred simultaneously with spermatophore dehiscence, showing the evolutionary relationship of the seminal receptacle and the female reproductive system to the storage of spermatophores and spermatozoa. © 2014 Marine Biological Laboratory.

    2015-10-01

    Full Text Available The migratory species piabanha does not reproduce in lentic environments since it requires environmental stimuli for the maturation and extrusion of gametes, and therefore hormonal induction is mandatory. Current study compares the seminal characteristics of Brycon insignis without any hormonal induction (Control - Ctrl and with two types of hormonal inductors, or rather, carp pituitary extract (T1 - 2.5 mg kg-1 body weight and GnRH analogues, the latter applied in two different concentrations (T2 - 0.7 mg kg-1 body weight and T3 - 1.4 mg kg-1 body weight. Post-induction analyses showed that the hormones increased the motility rate - Ctrl (95%, T1 (100%, T2 (100% and T3 (98%, although sperm concentration - Ctrl (11.52 x 109; T1 (4.37 x 109; T2 (4.34 x 109; T3 (4.01 x 109 decreased. Assessments for sperm vigor, motility time and spermatic morphology did not vary with hormonal induction. Hormonal inducer does not alter negatively the seminal characteristics of the piabanha, and the choice for the proper hormone depends on the preference of the dispenser.

    2007-07-01

    Molecules in male seminal fluid transferred to female insects during mating can have potent effects on their subsequent sexual and reproductive behaviour. Like many other tephritids, female Queensland fruit flies (Bactrocera tryoni) typically have diminished sexual receptivity after their first mating. Also, copulations of females that do remate tend to be shorter than those of virgins. We here find that virgin females injected with small doses (0.1, 0.2 or 0.5 male equivalents) of extracts from the male reproductive tract accessory tissues, which consist of male accessory glands, ejaculatory apodeme and ejaculatory duct (AG/EA/ED), have diminished receptivity and short copula duration very similar to naturally mated females. In contrast, virgin females injected with saline or with high doses of AG/EA/ED (1 or 2 male equivalents) that likely exceed the range of natural variation retain the higher levels of sexual receptivity and longer copulations of un-injected virgins. We conclude that reduced sexual receptivity and shorter copulations of mated female Q-flies are mediated by products in the male seminal fluid derived from the male reproductive tract accessory tissues.

    2013-01-01

    Background: Advances in the care of patients with cystic fibrosis (CF) have improved pulmonary outcomes and survival. In addition, rapid developments regarding the underlying genetic and molecular basis of the disease have led to numerous novel targets for treatment. However, clinical and basic scientific research focusing on therapeutic strategies for CF-associated chronic rhinosinusitis (CRS) lags behind the evidence-based approaches currently used for pulmonary disease. Methods: This review evaluates the available literature and provides an update concerning the pathophysiology, current treatment approaches, and future pharmaceutical tactics in the management of CRS in patients with CF. Results: Optimal medical and surgical strategies for CF CRS are lacking because of a dearth of well-performed clinical trials. Medical and surgical interventions are supported primarily by level 2 or 3 evidence and are aimed at improving clearance of mucus, infection, and inflammation. A number of novel therapeutics that target the basic defect in the cystic fibrosis transmembrane conductance regulator channel are currently under investigation. Ivacaftor, a corrector of the G551D mutation, was recently approved by the Food and Drug Administration. However, sinonasal outcomes using this and other novel drugs are pending. Conclusion: CRS is a lifelong disease in CF patients that can lead to substantial morbidity and decreased quality of life. A multidisciplinary approach will be necessary to develop consistent and evidence-based treatment paradigms. PMID:24119602

    Full Text Available Cystic fibrosis (CF is a multisystem disease with a range of abdominal manifestations including those involving the liver, pancreas, and kidneys. Recent advances in management of the respiratory complications of the disease has led to a greater life expectancy in patients with CF. Subsequently, there is increasing focus on the impact of abdominal disease on quality of life and survival. Liver cirrhosis is the most important extrapulmonary cause of death in CF, yet significant challenges remain in the diagnosis of CF related liver disease. The capacity to predict those patients at risk of developing cirrhosis remains a significant challenge. We review representative abdominal imaging findings in patients with CF selected from the records of two academic health centres, with a view to increasing familiarity with the abdominal manifestations of the disease. We review their presentation and expected imaging findings, with a focus on the challenges facing diagnosis of the hepatic manifestations of the disease. An increased familiarity with these abdominal manifestations will facilitate timely diagnosis and management, which is paramount to further improving outcomes for patients with cystic fibrosis.

    To understand variation in the aetiology, microbiology and burden of bronchiectasis and cystic fibrosis across different global healthcare systems.; Bronchiectasis is the term used to refer to dilatation of the bronchi that is usually permanent and is associated with a clinical syndrome of cough, sputum production and recurrent respiratory infections. It can be caused by a range of inherited and acquired disorders, or may be idiopathic in nature. The most well recognised inherited disorder in Western countries is cystic fibrosis (CF, an autosomal recessive condition that leads to progressive bronchiectasis, bacterial infection and premature mortality. Both bronchiectasis due to CF and bronchiectasis due to other conditions are placing an increasing burden on healthcare systems internationally. Treatments for CF are becoming more effective leading to more adult patients with complex healthcare needs. Bronchiectasis not due to CF is becoming increasingly recognised, particularly in the elderly population. Recognition is important and can lead to identification of the underlying cause, appropriate treatment and improved quality of life. The disease is highly diverse in its presentation, requiring all respiratory physicians to have knowledge of the different “bronchiectasis syndromes”. The most common aetiologies and presenting syndromes vary depending on geography, with nontuberculous mycobacterial disease predominating in some parts of North America, post-infectious and idiopathic disease predominating in Western Europe, and post-tuberculosis bronchiectasis dominating in South Asia and Eastern Europe. Ongoing global collaborative studies will greatly advance our understanding of the international impact of bronchiectasis and CF.

  4. Cystic Fibrosis and the Nervous System.

    Reznikov, Leah R

    2017-05-01

    Cystic fibrosis (CF) is a life-shortening autosomal recessive disorder caused by mutations in the gene encoding the cystic fibrosis transmembrane conductance regulator (CFTR). CFTR is an anion channel that conducts bicarbonate and chloride across cell membranes. Although defective anion transport across epithelial cells is accepted as the basic defect in CF, many of the features observed in people with CF and organs affected by CF are modulated by the nervous system. This is of interest because CFTR expression has been reported in both the peripheral and central nervous systems, and it is well known that the transport of anions, such as chloride, greatly modulates neuronal excitability. Thus it is predicted that in CF, lack of CFTR in the nervous system affects neuronal function. Consistent with this prediction, several nervous system abnormalities and nervous system disorders have been described in people with CF and in animal models of CF. The goal of this special feature article is to highlight the expression and function of CFTR in the nervous system. Special emphasis is placed on nervous system abnormalities described in people with CF and in animal models of CF. Finally, features of CF that may be modulated by or attributed to faulty nervous system function are discussed. Copyright © 2016 American College of Chest Physicians. Published by Elsevier Inc.

    Tuberculosis (TC) is very common and significant cause of morbidity and mortality worldwide. Isolated cystic duct lymph node TC cases without involvement of gallbladder are exceedingly rare. It is difficult to diagnose preoperatively because of lack of characteristic signs and symptoms of TC. We report a man aged 45 years who presented with right upper abdominal pain since 1week. It was associated with nausea and postprandial fullness. There was no evidence of jaundice and lymphadenopathy. Abdominal examination showed moderate right upper quadrant tenderness with positive Murphy's sign and splenomegaly but no signs of peritonism. Abdomen ultrasound revealed sludge in gallbladder, dilated pancreatic duct, coarse exotexture of liver, splenomegaly and no lymphadenopathy. He underwent laparoscopic cholecystectomy; histological report showed chronic caseating granulomatous lymphadenitis with Langhans type of giant cells in lymph node near cystic duct with chronic cholecystitis of gallbladder. Standard antituberculosis therapy was given for 12 months. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017. All rights reserved.

    In 1992 France set up a national cystic fibrosis observatory (Observatoire national de la mucoviscidose, ONM) to monitor the state of health of patients on an annual basis. Using the ONM data, this study estimates the main indicators for life expectancy and assesses the total number of cystic fibrosis patients. The data for the years 1994 to 2003 are divided into 3-year periods. Life tables are drawn up for these periods, from which mean and median lengths of life are determined. Using the most recent life table, the number of births in 2003 and the incidence of the disease, the total population of patients can be estimated, assuming a stationary population. In 2001-2003, life expectancy at birth of patients registered with the ONM was 39.1 years and median length of life was 36.4 years. These results, substantially better than those of 1994-1996, are linked to improved conditions of patient inclusion in the ONM database, to improvements in their healthcare, but also to the limitations of the life tables. Based on the 2003 data, the total theoretical number of patients is 6490, and coverage by the ONM database is thus 63.2%. These provisional results demonstrate the need to convert the ONM observatory into a registry providing exhaustive coverage of all patients.

    Diffuse cystic lung disease represents a diverse group of uncommon disorders with characteristic appearance on high resolution CT imaging. The combination of imaging appearance with clinical features and genetic testing where appropriate permits a confident and accurate diagnosis in the majority of the diseases without recourse for open lung biopsy. The mechanism of cyst development disease is unclear but in some disorders appears to be related to small airways obstruction. These diseases are incurable, with the exception of Langerhans cell histiocytosis which may spontaneously remit or resolve on smoking cessation. Disease progression is unpredictable; in general older patients have a more benign disease, while young patients may progress rapidly to respiratory failure. An understanding of the complications of cystic lung disease and the appearance of disease progression is essential for the management of these patients. A number of these disorders are associated with malignancy, recognition of the potential tumors permits appropriate imaging surveillance. Due to the widespread use of CT, pulmonary cysts are increasingly discovered incidentally in an asymptomatic individual. The diagnostic challenge is to determine whether these cysts represent an early feature of a progressive disease or have no clinical significance. In the elderly population the cysts are unlikely to represent a progressive disease. In individuals <50 years further evaluation is recommended.

    Full Text Available The incidence of cystic fibrosis-related diabetes (CFRD has increased, since the life expectancy of cystic fibrosis (CF patients continues to improve. CFRD increases the mortality in patients, because of the negative impacts of CFRD on pulmonary functions. Knowledge of the pathogenesis and course of the disease is essential to administer the appropriate therapy. A thirty-one-year-old CFRD patient, who had hypoglycemia and weight loss under the calorie restriction diet and basal insulin therapy, was admitted to the Endocrinology Department for revision of her therapy. A high-calorie diet considering increased energy demand and multiple insulin injections according the carbohydrate counting were administered to the patient. She gained weight and target blood glucose levels were achieved as a result of this therapy. We present the first case with CFRD followed in our clinic with the review of the literature about the pathogenesis, course and therapy of this disease to draw attention to a special kind of diabetes, which we will encounter more frequently.

    Airway infection and inflammation play major roles in the progression of cystic fibrosis (CF) lung disease. In patients with mild disease, airway inflammation is a clinically relevant and often underdiagnosed feature. Lung function, sputum cell counts, and cytokine profiles in CF with mild disease might be different in patients with and without involvement of small airway disease (SAD). Patients with mild CF (n=32) and 22 healthy controls were enrolled in this study. Patients with CF were assigned to two groups: (1) patients without SAD (n=19, median age 12.3years, MEF 25 >50% predicted), and (2) patients with SAD (n=13 median age, 13.2years, MEF 25 inflammation compared to controls as indicated by elevated levels of sputum biomarkers like total cells, neutrophils, and IL6. Our study demonstrated that patients with CF with mild disease defined by lung function might be further endotyped according to their involvement of SAD. In patients with CF and SAD, airway neutrophilic inflammation is more pronounced and is in part distinct from that seen in patients without SAD. Copyright © 2016 European Cystic Fibrosis Society.

    Waters, Valerie; Smyth, Alan

    2015-09-01

    Much of the improvement in the survival of individuals with cystic fibrosis (CF) is due to advancements in antimicrobial treatments. New aerosolized antibiotic formulations have recently been introduced (such as inhaled aztreonam), and others are in development (inhaled levofloxacin and liposomal amikacin). Licensed dry powder formulations include tobramycin inhalation powder and dry powder colistimethate (available in Europe). Although inhaled antibiotics have the advantage of being able to deliver high intrapulmonary concentrations of drug, antimicrobial resistance can still develop and is a concern in CF. Antimicrobial resistance might be mitigated by using non-antibiotic treatments, antibiotic adjuvants, which have activity against bacteria. Examples include agents such as gallium, antimicrobial peptides and anti-biofilm compounds such as alginate oligosaccharides (OligoG) and garlic. Vaccination strategies and antibody therapy (IgY) against Pseudomonas aeruginosa have also been attempted to prevent initial infection with this organism in CF. Although aggressive and long-term use of antibiotics has been crucial in slowing lung function decline and improving survival in people with CF, it has added a significant burden of care and associated toxicities in these individuals. Careful surveillance and the use of preventative strategies for antibiotic related toxicity (such as nephrotoxicity and ototoxicity) are essential. Continued development of effective antimicrobial agents that can function in the conditions encountered in the CF lung, such as against bacterial biofilm growth and under anaerobic conditions, is needed.

    1999-11-01

    When Watson and Crick determined the structure of DNA in 1953, a biological revolution began. One result of this revolution is the Human Genome Project. The primary goal of this international project is to obtain the complete nucleotide sequence of the human genome by the year 2005. Although molecular biologists and geneticists are most enthusiastic about the Human Genome Project, all areas of clinical medicine and fields of biology will be affected. Cystic fibrosis is the most common, inherited, lethal disease of white persons. In 1989, researchers located the cystic fibrosis gene on the long arm of chromosome 7 by a technique known as positional cloning. The most common mutation (a 3-base pair deletion) of the cystic fibrosis gene occurs in 70% of patients with cystic fibrosis. The knowledge gained from genetic research on cystic fibrosis will help researchers develop new therapies (e.g., gene) and improve standard therapies (e.g., pharmacologic) so that a patient's life span is increased and quality of life is improved. The purpose of this review is twofold. First, the article provides an overview of the Human Genome Project and its clinical significance in advancing interdisciplinary care for patients with cystic fibrosis. Second, the article includes a discussion of the genetic basis, pathophysiology, and management of cystic fibrosis.

    Cystic fibrosis-related diabetes (CFRD) is the end-point of a spectrum of glucose abnormalities in cystic fibrosis that begins with early insulin deficiency and ultimately results in accelerated nutritional decline and loss of lung function. Current diagnostic and management regimens are unable to entirely reverse this clinical decline. This review summarises the current understanding of the pathophysiology of CFRD, the issues associated with using oral glucose tolerance tests in CF and the challenges faced in making the diagnosis of CFRD. Medline database searches were conducted using search terms "Cystic Fibrosis Related Diabetes", "Cystic Fibrosis" AND "glucose", "Cystic Fibrosis" AND "insulin", "Cystic Fibrosis" AND "Diabetes". Additionally, reference lists were studied. Expert commentary: Increasing evidence points to early glucose abnormalities being clinically relevant in cystic fibrosis and as such novel diagnostic methods such as continuous glucose monitoring or 30 minute sampled oral glucose tolerance test (OGTT) may play a key role in the future in the screening and diagnosis of early glucose abnormalities in CF.

Esta espécie possui importância medicinal, pela presença dos vitaesteróides conhecidos como fisalinas e, atualmente, na alimentação. Essa espécie se propaga facilmente por sementes, motivo pelo qual ela é tida como infestante de outras culturas. Nesse sentido, a identificação da espécie ainda nos estágios iniciais de crescimento confunde com as demais infestantes, tornando difícil a sua caracterização taxonômica. Assim, o objetivo deste trabalho foi caracterizar morfologicamente as sementes e o desenvolvimento pós-seminal de Physalis angulata. Os ensaios foram desenvolvidos no Laboratório de Germinação da Unidade Experimental Horto Florestal, Feira de Santana - BA. Para tanto foram realizadas análises morfométricas das sementes (4 repetições de 25 e analisadas suas características externas e internas com auxilio de microscópico estereoscópico. Para a descrição das plântulas da espécie foram utilizadas placas de petri contendo duas folhas de papel filtro (4 repetições de 20 sementes e umedecidos com água destilada. As sementes foram colocadas em câmara de germinação à 35ºC (fotoperíodo de 12 horas até a emissão dos cotilédones. A metodologia para descrição do desenvolvimento pós-seminal foi realizada em condições de casa de vegetação e consistiu em avaliações realizadas cinco dias após a semeadura (emissão dos cotilédones e no intervalo de até 15 dias (emissão de eófilos e metáfilos no qual foram utilizados 2 repetições de 20 vasos. As sementes apresentaram em média 1,55 mm de comprimento, 1,26 mm de largura e 0,43 mm de espessura. O período de análise foi suficiente para caracterizar as sementes e plântulas da espécie, permitindo a adoção de critérios de anormalidade.Physalis angulata is also known as camapu, mullaca or juá-de-capote it belongs to the Solanaceae family

    Full Text Available The objective of the present study was detection, isolation, partial purification and immunobiochemical characterization of fertility associated protein in the seminal plasma of high prolific Karan fries bull. Seminal plasma of Karan Fries bull was partially purified by gel filtration chromatography and analyzed by 10% SDS-PAGE for their polypeptide profile. PAGE analysis revealed major band of 55 kDa, and 26 kDa. Hyperimmune serum was raised in rabbit against crude seminal plasma protein. Single precipitin line was observed in DID test when each of the partially purified 26 kDa and 55 kDa proteins were reacted with hyperimmune serum. These proteins were also found to be immunoreactive against hyperimmune serum in Western blot technique.

    Full Text Available De 1939 a 1940, a Fundação Rockefeller promoveu, nos Estados Unidos, o Rockefeller Foundation Communication Seminar, que discutiu os rumos dos estudos sobre comunicação. Em plena eclosão da Segunda Guerra Mundial, o seminário acabou se tornando um marco na história do campo da Comunicação. Este artigo busca examinar uma consequência pouco visível do Seminário Rockefeller: a substituição progressiva do vocábulo propaganda nos estudos sobre os media, nos Estados Unidos, pelo termo comunicação. Concluí-se que as atividades do seminário foram decisivas para a mudança de terminologia, que, por sua vez, teve impacto epistemológico no campo.

  18. The Analysis of Sialylation, N-Glycan Branching, and Expression of O-Glycans in Seminal Plasma of Infertile Men

    Full Text Available Carbohydrates are known to mediate some events involved in successful fertilization. Although some studies on the glycosylation of seminal plasma proteins are available, the total glycan profile was rarely analyzed as a feature influencing fertilization potential. In this work we aimed to compare some glycosylation traits in seminal plasma glycoproteins of fertile and infertile men. The following findings emerge from our studies: (1 in human seminal plasma the presence and alterations of O-linked glycans were observed; (2 the expression of SNA-reactive sialic acid significantly differs between asthenozoospermia and both normozoospermic (fertile and infertile groups; (3 the expression of PHA-L-reactive highly branched N-glycans was significantly lower in oligozoospermic patients than in both normozoospermic groups. Indication of the appropriate lectins that would enable the possibly precise determination of the glycan profile seems to be a good supplement to mass spectrum analysis. Extension of the lectin panel is useful for the further research.

    A major morbidity after total thyroidectomy is hypocalcemia. Although many clinical factors and laboratory studies have been correlated with both biochemical and symptomatic hypocalcemia, the ideal use and timing of these tests remain unclear. We hypothesize 1-h (PACU) parathyroid hormone (PTH) will identify patients at risk for symptomatic hypocalcemia. This prospective study evaluated 196 patients undergoing total thyroidectomy. Serum calcium and PTH levels were measured 1 h after surgery and on postoperative day 1 (POD1). Performance of a central compartment lymph node dissection, parathyroid autotransplantation, indication for procedure, pathology, and presence of parathyroid tissue in the pathology specimen were recorded. Of 196 patients, nine (4.6%) developed symptomatic hypocalcemia. Thirty four (17.3%) had a 1-h PACU PTH ≤10 pg/dL, whereas 31 (15.8%) had a POD1 PTH of ≤10. Five (56%) of the nine symptomatic patients underwent central compartment lymph node dissection, four (44%) had parathyroid autotransplantation, and four (44%) had a PACU PTH ≤10. PACU and POD1 PTH levels were correlated (R(2) = 0.682). Multivariate regression identified central compartment dissection, autotransplantation, and PACU or POD1 PTH correlated with symptomatic hypocalcemia. PACU PTH, POD1 PTH, PACU Ca, malignant final pathology, and age ≤45 y correlated with biochemical hypocalcemia. A 1-h postoperative PACU PTH is equivalent to POD1 PTH in predicting the development of symptomatic hypocalcemia. Biochemical hypocalcemia was not predictive of symptoms in the immediate postoperative period. Lymph node dissection and parathyroid autotransplantation correlated with symptomatic hypocalcemia and improve the sensitivity of biochemical screening alone. Copyright © 2016 Elsevier Inc.

    Cystic fibrosis is a genetically inherited, life-threatening condition that affects major organs. The management of cystic fibrosis involves a multi-faceted daily treatment regimen that includes airway clearance physiotherapy, taking pancreatic enzymes and other medications. Previous studies identified that compliance with this intensive treatment especially among adolescents with cystic fibrosis is poor. Because of both the nature and consequences of the illness and the relentless demands of treatments, many individuals with cystic fibrosis are likely to have a poor quality of life. Anecdotal evidence suggests that singing may provide rigorous exercises for the whole respiratory system as well as a means for emotional expression, which may enhance quality of life. To evaluate the effects of a singing intervention in addition to usual therapy on the quality of life, morbidity, respiratory muscle strength and pulmonary function of children and adults with cystic fibrosis. We searched the Group's Cystic Fibrosis Trials Register, the Cochrane Central Register of Controlled Trials, major allied complementary data bases, and clinical trial registers. Hand searching for relevant conference proceedings and journals was also carried out.Date of search of Trials Register: 02 September 2009.Date of additional searches: 17 September 2009. Randomised controlled trials in which singing (as an adjunctive intervention) is compared with either a sham intervention or no singing in people with cystic fibrosis. No trials were found that met the selection criteria. No meta-analysis could be performed. As no studies that met the criteria were found, this review is unable to support or refute the benefits of singing as a therapy for people with cystic fibrosis. Future randomised controlled trials are required to evaluate singing therapy for people with cystic fibrosis.

    Introduction and objective: Vasectomy is a well-established method in family control. Even though it is a safe and low risk operation, this surgery is invasive and difficult to reverse. Therefore the aim of this study was to investigate new non-invasive methods for occlusion of the seminal duct. Material and Methods: Seminal duct tissue was obtained from patients (n=30) suffering from prostate cancer and therefore undergoing prostatectomy. In a first set of experiments, the seminal duct was occluded by intraluminal application of Histoacryl® (Braun Aesculap AG, Tuttlingen, Germany). In a 2nd set of experiments, endoluminal laser induced occlusion was performed. Four different laser wavelengths (1940nm, 1470nm, 1064nm, 940nm) and different sets of laser parameters (e.g. power, exposure duration, fibre diameter, energy applied) were compared. Effectiveness of occlusion of the seminal duct was proven by post-treatment irrigation flow measurement, as well as by morphological analyses. To evaluate a potential damage of the surrounding tissue, external temperature was measured using a thermometer during laser application. Results: Intraluminal application of Histoacryl® induced an immediate and complete occlusion of the seminal duct. The underlying connective tissue maintained its functional integrity after this treatment. By laser light application to a Histoacryl® block, a hole could be created into the block thus indicating the possibility of recanalization. Treatment with laser energy resulted in shrinkage of the ductal lumen. The laser application generally caused necrosis in the epithelium and induced formation of vacuoles in the underlying connective tissue. As described for endoluminal varicose treatment, this distinct local reaction might result in an intense inflammation leading to a functional occlusion of the vas deferens. Conclusions: Both laser-induced occlusion and application of Histoacryl® are fast and simple techniques which may be able to achieve a

    Full Text Available It was demonstrated that combination antiretroviral therapy (cART reduces the HIV-1 viral load (VL in the blood and the seminal compartment. Some studies have reported that the seminal HIV-1 VL is undetectable in individuals with an undetectable blood plasma viral load (bpVL under cART. However, some recent studies have demonstrated that seminal HIV-1 RNA may still be detected, and potentially infectious, even in the case of an undetectable bpVL. The aim of this retrospective study was to determine the detection rate of a seminal VL and whether shedding could be intermittent over a very short time. From January 2006 to December 2011, 88 HIV-1 infected men, enrolled in an Assisted Reproduction program, provided 306 semen samples, corresponding to 177 frozen sperm samples (two samples delivered at a one-hour interval (n = 129 or one sample (n = 48. All enrolled men were under cART, with an undetectable bpVL for more than 6 months. HIV-1 RNA was quantified in seminal plasma using a Roche COBAS Ampliprep COBAS TaqMan HIV-1 test. Seminal HIV-1 RNA was detected in 23 samples (7.5% from 17 patients (19.3%. This detection rate was stable over years. With regards to the freezing of two samples delivered at a one-hour interval, the proportion of discordance between the first and second samples was 9.3% (12/129. Our results confirm the intermittent shedding of HIV-1 in semen. While this finding has been shown by studies examining longer time intervals, to our knowledge, this has never been demonstrated over such a short time interval.

    Full Text Available OBJECTIVE: To determine through preoperative serum PSA level, Gleason score on biopsy and percentage of fragments affected by tumor on biopsy, the probability of involvement of the seminal vesicles. MATERIALS AND METHODS: During the period between March 1991 to December 2002, we selected 899 patients undergoing radical prostatectomy for treatment of localized prostate adenocarcinoma. The analyzed preoperative variables were PSA, percentage of positive fragments and Gleason score on the biopsy. Pre-operative PSA was divided in scales from 0 to 4.0 ng/mL, 4.1 to 10 ng/mL, 10.1 to 20 ng/mL and > 20 ng/mL, Gleason score was categorized in scales from 2 to 6. 7 and 8 to 10, and the percentage of affected fragments was divided in 0 to 25%, 25.1% to 50%, 50.1% to 75%, and 75.1% to 100%. All these variables were correlated with the involvement of seminal vesicles in the surgical specimen. RESULTS: Of the 899 patients under study, approximately 11% (95% CI, [9% - 13%] had involvement of seminal vesicles. On the multivariate analysis, when PSA was < 4, the Gleason score was 2 to 6, and less than 25% of fragments were involved on the biopsy, only 3.6%, 7.6% and 6.2% of patients respectively, had involvement of seminal vesicles. On the multivariate analysis, we observed that PSA, Gleason score and the percentage of involved fragments were independent prognostic factors for invasion of seminal vesicles. CONCLUSION: The preoperative variables used in the present study allow the identification of men with minimal risk (lower than 5% if involvement of seminal vesicles.

    Cystic fibrosis is an inherited, autosomal, recessive disease. This disorder is caused by defects in the gene for cystic fibrosis transmembrane conductance regulator (CFTR), which encodes for a protein that functions as a chloride channel. Mutations in the gene for CFTR result in ion disorders, and consequently in disturbances of exocrine glands in the respiratory, gastrointestinal, and genitourinary tracts. Pulmonary involvement occurs in 90% of patients, and is the main cause of death. The diagnosis of CF in Poland is based on clinical symptoms and positive results of the sweat test. Diacrisis is usually reached late in the 3 rd year of life. In 1999-2003, newborn screening examinations were performed at the Mother and Child Institute. The idea of these studies was to establish a diagnosis and begin treatment as early as possible, even in the asymptomatic period of the disease. The level of immunoreactive trypsinogen was determined in the blood of 4-6-day-old newborns, as well as the mutation of gene CFTR. The mean age of CF diagnosis was about 38 days. The aim of our study was to assess the influence of early commencement of treatment on the rapidity of progression of pulmonary involvement. 59 children with CF diagnosed by screening were examined by chest radiography in various periods of the disease, the earliest in the neonatal period. Pulmonary involvement (hyperinflation, periobronchial thickening, pulmonary nodules, cysts, parenchymal density, atelectasis and fibrous changes) were assessed according to Brasfield score. The control group consisted of 19 children with symptomatic CF, born in 1997-2003.They were also examined by chest radiography. Various pulmonary changes were recognized in 42 children diagnosed by screening. In the control group pulmonary involvement was found in 16 children. In both groups progression was found in 28% of the children, but significant progression was seen in 7% of those children with a screening diagnosis, and in 25% of the

    Segmental cystic disease of the kidney is a rare form of cystic disease of the kidney that manifests as variable sized, numerous cysts that are localized in a segment of one kidney. Morphologically and pathologically, it is indistinguishable from autosomal dominant polycystic kidney disease except for its unilateral localization, the lack of an autosomal dominant genetic background and the progressive deterioration of the renal function. We experienced a case of surgically confirmed segmental cystic disease of the kidney in a 49-year-old patient and we report on its ultrasonographic and CT findings, along with a brief review of the relevant literature

    Full Text Available Pneumomediastinum usually occurs after assisted ventilation. Spontaneous pneumomediastinum without preceding assisted ventilation, and presenting as a huge cystic mass in a term newborn infant has rarely been reported. We report a term baby who developed respiratory distress at 2 days of age. A huge cystic tumor of the thymus or a congenital mediastinal cystic tumor was initially suggested by chest radiography and computed tomography. Follow-up chest film revealed a “spinnaker sail sign” which is a typical radiographic presentation of pneumomediastinum.

    Quantitative immunoprecipitation and immunoradiometric assays have been developed for a protein present in the serum of cystic fibrosis homozygotes, and to a lesser extent in the serum of heterozygotes. When tested on a panel of sera from 14 cystic fibrosis patients, 29 heterozygotes and 23 controls, the immunoprecipitation assay allowed correct assignments to be made on 94% of occasions with one batch of antiserum and 95% with another. With the same panel of sera, the immunoradiometric assay allowed 94% correct assignments. It is suggested that such accuracy is the maximum that can be expected in the present state of knowledge of cystic fibrosis. (author)

    Five cystic mass lesions of the pancreas were exemined by MRI. Multiplocular fluid components were demonstrated as areas of various signal intensity in mucinous cystadenoma and cystadenocarcinoma. Gas within the cystic mass was noted in ductectatic mucinous cystadenocarcinoma. Honeycomb pattern and classification were not depicted in serous cystadenoma. Necrotic matter was demonstrated as area of lower signal than liver in pseudocyst. These results were then compared with CT and ultrasound and at present enhanced CT combined with ultrasound is more diagnostic than MRI for cystic mass lesions of the pancreas.

    We report the case of a 43-year-old man who presented with an osteolytic and expansive lesion in the left distal femur mimicking a giant cell tumor. Magnetic resonance imaging (MRI) showed that most of the lesion was cystic, and histological examination revealed fibrous dysplasia with marked cystic degeneration. Radiographic findings of cystic fibrous dysplasia in the end of a long bone may be similar to those of a giant cell tumor, and a biopsy is essential for the final diagnosis. (orig.)

    Surgery has been the classic treatment of choice for benign cystic diseases, including lymphatic malformation, ranula, branchial cleft cyst, thyroglossal duct cyst, thyroid cyst, parathyroid cyst, and lymphocele. However, surgery is associated with a tendency toward recurrence and may be accompanied by various complications, such as nerve injuries, vascular injuries, and scar formation. Therefore, sclerotherapy using various agents has been applied successfully to treatment of benign cystic diseases in the neck. This editorial reviews the use of various sclerotic agents and application of sclerotherapy to benign cystic diseases in the neck.

    Cystic lymphangioma is an uncommon mesenteric tumor which is usually reported in children. We describe a case of a 12-years old girl who was admitted in our hospital with abdominal distension and pain. Physical examination showed an abdomino-pelvic mass. Preoperative studies including abdominal ultrasonography and computed tomography failed to determine the cause of the pain. Laparotomy found a giant cystic tumor of the small bowel mesentery. Histological studies confirm the diagnosis of cystic lymphangioma. Based on this case, a review of the literature is suggested. PMID:22145071

    A case of a surgically confirmed cystic lymphangioma of the spleen is presented. Preoperative imaging consisted of US, contrast-enhanced CT and MRI, all showing a multiloculated lesion with small cystic cavities divided by thin septa, corresponding to dilated lymphatic spaces. Preoperative studies correlated well with the pathologic findings. Cystic lymphangioma of the spleen is a very rare condition and is usually solitary and asymptomatic. Large lymphangiomas may be an indication for splenectomy, since the risk of rupture is high even from minor abdominal trauma. Preoperative diagnosis may be achieved with correlated noninvasive imaging. (orig.)

    The Republic of Ireland has one of the highest reported incidences of cystic fibrosis (CF) in the world (1/1353) with an estimated carrier rate of 1/20. No cure exists, however there have been significant advances in available treatments. Newborn bloodspot screening (NBS) for CF was added to the NBS programme in Ireland in July 2011. Little is known about antenatal or postnatal women's knowledge about CF. This was a cross-sectional study of 662 antenatal (≥36weeks gestation) and 480 postnatal women (post NBS). Women were asked to self-complete a questionnaire including 14 CF knowledge questions. Among the respondents significantly more postnatal than antenatal women were aware that CF is included on the NBS (81.8% vs 63.5%; pdiagnosis. Copyright © 2015 European Cystic Fibrosis Society.

    Non-invasive ventilation may be a means to temporarily reverse or slow the progression of respiratory failure in cystic fibrosis by providing ventilatory support and avoiding tracheal intubation. Using non-invasive ventilation, in the appropriate situation or individuals, can improve lung mechanics through increasing airflow and gas exchange and decreasing the work of breathing. Non-invasive ventilation thus acts as an external respiratory muscle. This is an update of a previously published review. To compare the effect of non-invasive ventilation versus no non-invasive ventilation in people with cystic fibrosis for airway clearance, during sleep and during exercise. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register comprising references identified from comprehensive electronic database searches, handsearching relevant journals and abstract books of conference proceedings. We searched the reference lists of each trial for additional publications possibly containing other trials.Most recent search: 08 August 2016. Randomised controlled trials comparing a form of pressure preset or volume preset non-invasive ventilation to no non-invasive ventilation used for airway clearance or during sleep or exercise in people with acute or chronic respiratory failure in cystic fibrosis. Three reviewers independently assessed trials for inclusion criteria and methodological quality, and extracted data. Ten trials met the inclusion criteria with a total of 191 participants. Seven trials evaluated single treatment sessions, one evaluated a two-week intervention, one evaluated a six-week intervention and one a three-month intervention. It is only possible to blind trials of airway clearance and overnight ventilatory support to the outcome assessors. In most of the trials we judged there was an unclear risk of bias with regards to blinding due to inadequate descriptions. The six-week trial was the only one judged to have a low risk of bias for all

    Dutch (ex-)servicemen who encounter health problems since return from the 1992-3 peace operation UNTAC, commonly complain of reduced activity levels, decreases in physical fitness and aggravation of symptoms after strenuous exercise. To evaluate these symptoms. A prospective study of 26 symptomatic Cambodia veterans and 26 matched controls (healthy Cambodia veterans). Using an actometer and diaries, both groups were followed for a 12-day baseline period prior to an incremental maximal exercise test on a bicycle ergometer, followed by 7 days of post-ergometer data. During baseline, symptomatic Cambodia veterans reported more symptoms, had lower levels of physical activity and took longer periods of rest after high activity periods. Symptomatic veterans did not perceive the exercise test needing more exertion than healthy veterans did, although their physical fitness was decreased. Post-ergometer, daily observed symptoms did not aggravate in symptomatic veterans. Four days post-ergometer, actometer and daily observed activity scores were lowered in both groups. As compared to baseline, one day post-ergometer, levels of physical activity were changed in healthy veterans, but not in controls. Complaints about reduced activity levels and decreases in physical fitness in symptomatic Cambodia veterans were confirmed. Post-exertion malaise was not found. The observed post-exertion effects were traced back to weekday patterns.

    DYT1 mutation is characterized by focal to generalized dystonia and incomplete penetrance. To explore the complex perturbations in the different neural networks and the mutual interactions among them, we studied symptomatic and asymptomatic DTY1 mutation carriers by resting-state functional MRI. A total of 7 symptomatic DYT1, 10 asymptomatic DYT1, and 26 healthy controls were considered.

DYT1 mutation signature (symptomatic DYT1 and asymptomatic DYT1) was characterized by increased connectivity in the dorsal attention network and in the left fronto-parietal network. Functional correlates of symptomatic DYT1 patients (symptomatic DYT1 vs healthy controls) showed increased connectivity in the sensorimotor network. This study argues that DYT1 dystonia is a network disorder, with crucial nodes in sensory-motor integration of posterior parietal structures. A better characterization of cortical networks involved in dystonia is crucial for possible neurophysiological therapeutic interventions. © 2016 International Parkinson and Movement Disorder Society. © 2016 International Parkinson and Movement Disorder Society.

    Full Text Available The objective of this study was to evaluate the effects of egg yolk and seminal plasma on the viability of cryopreserved goat semen. To this end, four fertile Saanen bucks, aged between 10 months and 1 year, and weighing 18 to 25 kg, were used. Semen was collected from each buck by the artificial vagina method at the end of breeding season (June-July. The extender used was the yolk citrate, which was split into two equal aliquots: 5% egg yolk (2.5 mL egg yolk: 47.5 mL citrate solution were added to one of the samples and 10% egg yolk (5.0 mL egg yolk: 45.0 mL citrate solution were added to another. The sperm motility and vigor after thawing and post thermal resistance test (TRT were evaluated and the data were subjected to analysis of variance and means were compared by the F test at 5.0% probability. The observed values for motility and vigor after thawing and post thermal resistance test (TRT, fast and slow, according to the presence of seminal plasma and egg yolk percentage were: 5% egg yolk with plasma (25.0% and 3.3; 1.60% and 0.7; 12.36% and 1.6, respectively; 5% egg yolk without plasma (23.61% and 3.1; 1.25% and 0.2; 9.93% and 1.3, respectively; 10% egg yolk with plasma (30.8% and 3.3; 4.4% and 1.9; 19.5% and 2.7, respectively; and 10% egg yolk without plasma (13.4% and 2.5; 4.1% and 0.5; 17.0% and 1.0, respectively. There were significant differences between the analyzed data in relation to semen with or without plasma at different percentages of egg yolk, and the group that presented the best results was 10% egg yolk citrate in extender with plasma. The presence of seminal plasma and higher concentration of egg yolk in extender provide a higher viability of cryopreserved goat semen.

    Full Text Available Introcuction: Adenoid cystic carcinoma (ACC is the second most common salivary glands tumor and the most common malignant tumor of minor salivary glands and also submandibular glands; however ACC of the larynx and trachea is rare. These tumors generally present in subglottic region as smooth submucosal solid mass without ulceration. Their primary symptoms are often as respiratory problems. Materials and Methods: This study was done on a woman, 54 years, with subglottic ACC that presented with exertional dyspnea, stridor, cough and hoarseness. After confirmation of diagnosis with biopsy, the patient underwent a total laryngectomy and then postoperative radiotherapy. Conclusion: During one year follow up, the patient did not show any evidence of local recurrence or distant metastasis. Surgery with free margins in combination with postoperative radiotherapy was recommended to treat laryngeal ACC in order to obtain better survival.

    Cystic fibrosis (CF) is an autosomal recessive disease characterized by respiratory and intestinal insufficiencies. It has been reported in the literature that patients with CF show delayed growth and puberty and girls with CF achieve menarche at older age than normal females. Infertility, in both sexes, and menstrual dysfunction, in girls, are common in patients with CF. Previous data suggest that the degree of failure of growth and development is correlated with malnutrition and severity of progressing pulmonary disease. Despite improved nutrition and intensive treatment, patients with CF have delayed puberty and growth pubertal spurt. This maturational lag is accompanied by a significant delay in attaining pubertal levels of insulin-like growth factor-I (IGF-I), luteinizing hormone (LH), follicle-stimulating hormone (FSH) and sex steroid hormones.

    A 22 years-old female patient who began feeling some pain in the upper hemi abdomen that became intensive after food consumption and the feeling of having eaten too much. The serum amylase levels were within the normal limits. The imaging studies both echography and computerized axial tomography disclosed a well-defined and vascularized tumor mass in the tail of pancreas. She was operated on to completely remove the lesion. The anatomopathological study confirmed the diagnosis of solid and cystic pancreatic papillary carcinoma. Later on, the patient received chemotherapy and radiotherapy. The evolutional imaging tests did not show either local relapses or distant metastasis. The patient responded well to treatment and her health status is good nowadays

    Patients with cystic fibrosis (CF) are at increased risk of nasal polyps. We present the case of a 17-month-old Caucasian patient with CF who presented with hypertelorism causing cycloplegic astigmatism, right-sided mucoid discharge, snoring and noisy breathing. Imaging suggested bilateral mucoceles in the ethmoid sinuses. Intraoperatively, bilateral soft tissue masses were noted, and both posterior choanae were patent. Polypectomy and bilateral mega-antrostomies were performed. Histological examination revealed inflammatory nasal polyposis typical of CF. The role of early functional endoscopic sinus surgery (FESS) in children with CF nasal polyposis remains questionable as the recurrence rate is higher, and no improvement in pulmonary function has been shown. Our case, however, clearly demonstrates the beneficial upper airway symptom relief and normalisation of facial appearance following FESS in a child with this condition. 2016 BMJ Publishing Group Ltd.

  4. Diabetes mellitus in childhood cystic fibrosis.

    2012-02-03

    Since 1984, five patients in the cystic fibrosis (CF) clinic at Cork Regional Hospital have developed diabetes mellitus (DM) and were treated with Insulin. None had received systemic corticosteroids but two had high calorie naso-gastric feeding regimes. Two died from lung disease. A fifteen year old boy developed bilateral cataracts. In nine other paediatric CF clinics in the Republic of Ireland (total: 420 patients), three patients have DM, two receiving Insulin. Abnormal glucose tolerance is becoming more common in CF as patients survive longer. The possible role of corticosteroid treatment and intensive carbohydrate feeding regimes in development of glucose intolerance must be considered. DM in CF differs from the usual childhood DM. Regular screening and early Insulin supplementation may be beneficial.

    Poly Cystic Ovarian Syndrome (PCOS) is one of the most common metabolic and reproductive disorders among women of reproductive age. Women suffering from PCOS present with a constellation of symptoms associated with menstrual dysfunction and androgen excess, which significantly impacts their quality of life. They may be at increased risk of multiple morbidities, including obesity, insulin resistance, type II diabetes mellitus, cardiovascular disease (CVD), infertility, cancer, and psychological disorders. This review summarizes what the literature has so far provided from guidelines to diagnosis of PCOS. It will also present a general overview about the morbidities associated with this disease, specifically with its more severe classic form. Finally, the review will stress on the various aspects of treatment and screening recommendations currently used in the management of this condition.

    We report the case of a 23-year-old female patient, who was admitted to our hospital because of aggravating pain in the right shoulder, right chest and ear accompanied by cough and dyspnea. Imaging revealed a soft tissue mass in the mediastinum in close relation with an additional large mass extending in the right upper thorax, right axilla and neck. The tissue obtained during surgery showed the former mass to be a cystic thymoma, being in contact with an extensive vascular dysplasia. The characteristic clinical presentation, the contribution of imaging, the results of operation, and the follow-up are rather unique. The review of the literature did not reveal similar cases.

    Fibroadenoma is the most common breast tumor in adolescent and young women. Fibroadenomas that consist of sclerosing adenosis, papillary apocrine metaplasia, epithelial calcifications, and/or cysts greater than 3 mm are considered as complex fibroadenoma. The relative risk of developing breast cancer in patients with complex fibroadenoma is increased, compared to women with noncomplex fibroadenoma. Extensive cystic degeneration in a fibroadenoma, so called "cystic fibroadenoma" is very rare. Herein, we present a case of such a lesion in a 43-year-old female who has been on follow-up for fibrocystic changes of the breast, and discuss both radiological and histopathologic differential diagnosis of this lesion with other cystic lesions of the breast, including cystic papilloma. The patient is free of disease after 17 months of clinical follow-up.

    The addition of Doppler technology to an ultrasound imaging system allows easy differentiation of vascular from nonvascular masses. In addition, the characteristic flow in different arteries, veins, and arteriovenous communications allows accurate diagnosis of vascular structures. Cystic lesions in the region of the midbrain are uncommon but not rare in neonates, and it is important to differentiate between quadrigeminal plate cysts and vein of Galen aneurysms. Six neonates with cystic midbrain structures lying above the tectum were studied over a 2-year period. All were examined with duplex Doppler imaging and followed up by CT and angiography, when indicated. In two of the six infants a highly vascular signal was demonstrated with high flow rates and low impedance. Subsequent CT and angiography revealed typical vein of Galen aneurysms. The remaining four infants had cystic lesions that were avascular on Doppler imaging and demonstrated no enhancement on CT. Duplex Doppler imaging is helpful in the initial investigation of patients with midbrain cystic lesions

    Cystic fibrosis is the most common fatal autosomal recessive disease affecting Caucasian populations. It remains a puzzle how this disease is maintained at such a remarkably high incidence, however, it could be due to a reproductive advantage in cystic fibrosis heterozygotes. We tested...... this hypothesis. An adult Danish general population sample of 9141 individuals was screened for cystic fibrosis DeltaF508 heterozygotes; 250 carriers of this mutation were identified (2.7%). In the total sample DeltaF508 heterozygotes did not have more children than noncarriers; however, smoking interacted.......001). In conclusion, overall these results do not support a reproductive advantage for cystic fibrosis DeltaF508 heterozygotes. However, the data cannot totally exclude the possibility that nonsmoking DeltaF508 heterozygotes experience a reproductive advantage while smoking DeltaF508 heterozygotes experience...

    2003-01-01

    Full Text Available Cystic fibrosis is a genetic disease usually diagnosed by abnormal sweat testing. We report a case of an 18-year-old female with bronchiectasis, chronic P. aeruginosa infection, and normal sweat chloride concentrations who experienced rapid decrease of lung function and clinical deterioration despite treatment. Given the high suspicion ofcystic fibrosis, broad genotyping testing was performed, showing a compound heterozygous with deltaF508 and 3849+10kb C->T mutations, therefore confirming cystic fibrosis diagnosis. Although the sweat chloride test remains the gold standard for the diagnosis of cystic fibrosis, alternative diagnostic tests such as genotyping and electrophysiologic measurements must be performed if there is suspicion of cystic fibrosis, despite normal or borderline sweat chloride levels.

    Cystic duct remnant mucocele is an extremely rare complication of liver transplantation in children. Surgical correction is usually required for cystic duct remnant mucocele when it causes biliary obstruction. We describe a 14-month-old liver transplant recipient who presented with biliary obstruction 1 month after orthotopic liver transplantation with an end-to-end choledochocholedocal biliary anastomosis for hepatoblastoma. US, CT and cholangiography findings were consistent with mucocele of the allograft cystic duct remnant. Surgery was not needed in our patient because the mucocele and biliary obstruction had resolved on repeat imaging most likely due to guidewire manipulation during cholangiography, resulting in opening of the cystic duct remnant orifice and drainage into the common duct.

    Full Text Available Gene therapy is an alternative treatment for genetic lung disease, especially monogenic disorders such as cystic fibrosis. Cystic fibrosis is a severe autosomal recessive disease affecting one in 2500 live births in the white population, caused by mutation of the cystic fibrosis transmembrane conductance regulator (CFTR. The disease is classically characterized by pancreatic enzyme insufficiency, an increased concentration of chloride in sweat, and varying severity of chronic obstructive lung disease. Currently, the greatest challenge for gene therapy is finding an ideal vector to deliver the transgene (CFTR to the affected organ (lung. Adeno-associated virus is the most promising viral vector system for the treatment of respiratory disease because it has natural tropism for airway epithelial cells and does not cause any human disease. This review focuses on the basic properties of adeno-associated virus and its use as a vector for cystic fibrosis gene therapy.

    To estimate the overall prevalence of complementary and alternative medicine use among children with cystic fibrosis, determine specific modalities used, predictors of use and subjective helpfulness or harm from individual modalities. Of 53 children attending the cystic fibrosis clinic in London, Ontario (100% recruitment), 79% had used complementary and alternative medicine. The most commonly used modalities were air purifiers, humidifiers, probiotics, and omega-3 fatty acids. Family complementary and alternative medicine use was the only independent predictor of overall use. The majority of patients perceived benefit from specific modalities for cystic fibrosis symptoms. Given the high frequency and number of modalities used and lack of patient and disease characteristics predicting use, we recommend that health care providers should routinely ask about complementary and alternative medicine among all pediatric cystic fibrosis patients and assist patients in understanding the potential benefits and risks to make informed decisions about its use.

  2. Interdisciplinary Management of Cystic Neoplasms of the Pancreas

    Directory of Open Access Journals (Sweden)

    Linda S. Lee

    2012-01-01

    Full Text Available Cystic neoplasms of the pancreas are increasingly recognized due to the frequent use of abdominal imaging. It is reported that up to 20% of abdominal cross-sectional scans identify incidental asymptomatic pancreatic cysts. Proper characterization of pancreatic cystic neoplasms is important not only to recognize premalignant lesions that will require surgical resection, but also to allow nonoperative management of many cystic lesions that will not require resection with its inherent morbidity. Though reliable biomarkers are lacking, a wide spectrum of diagnostic modalities are available to evaluate pancreatic cystic neoplasms, including radiologic, endoscopic, laboratory, and pathologic analysis. An interdisciplinary approach to management of these lesions which incorporates recent, specialty-specific advances in the medical literature is herein suggested.

    Adenoid cystic carcinoma is a malignant minor salivary gland tumor that represents laryngeal tumors. The submucosal location of laryngeal adenoid cystic carcinoma (LACC) results in delayed presentation. Here, we present the first systematic review of reported cases of LACC to determine trends in presentation, diagnostic and treatment modalities, and patient outcome. PubMed, Web of Science, MEDLINE, and EMBASE databases. A search of the above databases was done to identify articles reporting cases of LACC. The variables included in the analysis were patient demographics, presenting symptoms, tumor location, imaging, treatment, follow-up time, recurrence, and outcome. A total of 50 articles and 120 cases were included in the review. The most common presenting symptom was dyspnea (48.8%), followed by hoarseness (43.9%). LACC arose most frequently from the subglottis (56.7%). At presentation, 14.6% (13 of 89) of patients had regional disease. The average follow-up time was 54.0 months. At follow-up, distant metastasis was reported in 30 cases (33.3%). Surgery alone (43.3%) and surgery with radiotherapy (43.3%) were used most frequently and resulted in 57.1% and 55.3% of patients alive with no evidence disease at follow-up, respectively. LACC was most often located in the subglottis. Patients commonly presented with dyspnea and hoarseness. In this systematic review, surgery with radiotherapy and surgery alone were the most commonly employed treatment modalities, and both resulted in slightly more than 50% of patients alive with no evidence of disease at follow-up. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

    Electrochemical skin conductance measurement is an active electrophysiologic method in which incremental low direct voltage is applied on the skin. It generates a current due to reverse iontophoresis which previous studies suggested to be mostly related to chloride anion movements. As sweat chloride movements upon electric stimulation were likely to be impaired in cystic fibrosis (CF) patients, we designed a proof-of-concept study to measure electrochemical skin conductance in CF patients and control subjects and to test the ability of this method to discriminate CF from controls. Electrochemical skin conductance was measured in 41 adult patients with classical CF and 20 healthy control subjects. Patients placed their hands and feet on nickel electrodes and an incremental low direct voltage was applied on the anode during 2min. The resulting voltage on the cathode and the current generated between anode and cathode were measured and from them, two electrochemical skin conductance variables were calculated: ESC, obtained when a low voltage of 1.6V was applied, and dESC which took into account electrochemical skin conductances obtained when low and high voltages were applied. ESC measurements on hands and feet were significantly different in CF patients (on feet: 75±10μSi), as compared with control subjects (62±13μSi, pconductance which is easily and rapidly measured is abnormal in CF patients.

    Full Text Available Cystic echinococcosis (CE is caused by the tapeworm, Echinococcus granulosus. The tapeworms resides in the small intestines of canids and the lifecycle involves both intermediate and definitive hosts. Humans are accidental intermediate hosts. Cystic echinococcosis is an economically important infection constituting a threat to public health, and is considered an emerging disease around the world. There are at least 10 Echinococcus strain types (G1 – G10, each exhibiting diversity of morphology, development and host range. The epidemiology of CE is poorly understood in South Africa. A retrospective data analysis of the National Health Laboratory Service (NHLS laboratory information system on echinococcosis serology, microscopy and histopathology results in eight provinces (excluding KwaZula-Natal showed an overall positivity rate in submitted diagnostic samples of 17.0% (1056/6211, with the Eastern Cape (30.4%, North West (19.0% and Northern Cape (18.0% provinces showing highest rates. The data showed considerable variability between provinces. The review also showed that most proven cases were negative on serology, implying that the actual number of patients could be underestimated. To our knowledge, no data exist about the prevalent strains of E. granulosus and this prospective study will attempt to fill that gap. The aim is to genotype strains causing the disease in South Africa. Two different polymerase chain reaction (PCR methods will be used to respectively target the 12S rRNA and nad 1 genes. To date, three samples have been genotyped as G1, G5 and G6; suggesting diversity of strains prevalent in the country, but more data is needed for a clearer picture.

    The authors retrospectively assessed the usefulness of postoperative radiation therapy after local resection of adenoid cystic carcinoma, with emphasis on organ-conserving treatment and the cosmetic results. Between 1985 and 1995, 32 patients underwent local resection followed by postoperative radiation therapy with curative and organ-conserving intent. None of patients received any form of chemotherapy as part of their initial treatment. Radiation therapy was carried out by techniques that were appropriate for the site and extension of each tumor. The 5-year local control, disease-free, and overall survival rates of all patients were 76%, 68%, and 86%, respectively. The 5-year local control rate and disease-free survival rate of patients with microscopically positive margins were 89% and 75%, respectively, and higher than in patients with macroscopically residual disease, but no significant difference in 5-year overall survival rate was observed. The postoperative cosmetic results in 29 patients with head and neck lesions were evaluated. No difference was documented between the cosmetic results postoperatively setting and after postoperative radiotherapy, and no significant differences in cosmetic results were observed according to radiation dose. The combination of local resection with organ-conserving intent and postoperative radiation therapy provided good cosmetic results in patients with T1 or T2 lesions. Postoperative radiation therapy with smaller fractions is useful, because good local control can be achieved in patients with adenoid cystic carcinoma having microscopically positive margins without inducing any late adverse reactions. However, the number of patients was too small and the follow-up period was too short to draw any definite conclusion in regard to fraction size. A much longer follow-up study with a larger number patients will be required to accurately determine the optimal treatment intensity and duration of treatment. (K.H.)

    The objectives of this study were to determine the influence of breed and hybrid genetic traits of boars on lipid and protein concentrations and antioxidative system variables in seminal plasma (SP) and spermatozoa and their correlations with semen quality variables. Semen samples from 27 boars: Swedish Landraces (SL), German Landraces (GL), Large Whites (LW), Pietrains (P) and Pig Improvement Company hybrids (PIC-hybrid), aged from 1.5 to 3 years old, were collected. SP was spectrophotometrically analyzed to determine total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triacylglycerol (TAG), total protein (TP), albumin, and zinc concentrations. The antioxidative system in SP and spermatozoa was established spectrophotometrically by determining total antioxidative status (TAS), total superoxide dismutase (TSOD) and glutathione peroxidase (GSH-Px) parameters, as well as copper-zinc superoxide dismutase (CuZnSOD) and manganese superoxide dismutase (MnSOD) activity in spermatozoa. The hybrid boars had higher (Pspermatozoa of: TAS and CuZnSOD than SL; TSOD and GSH-Px than SL and P; and MnSOD than SL and LW. Differences in SP and spermatozoa antioxidative system variables and the significant differences in SP protein and lipid variables exist among boars of different breeds and hybrid. Novel data and observed differences in semen variables among boar breeds and hybrids and their correlations with semen quality parameters in this study could contribute to better assessment of boar semen quality.

    Optimizing cryopreservation protocols for nondomestic felids contributes to the successful development of assisted reproduction techniques and genetic resource banking. In this study, we describe a simple cryopreservation procedure for African lion (Panthera leo) ejaculates, which was tested with different packaging options and different sperm numbers per dose. By applying urethral catheterization and electroejaculation, 17 ejaculates with greater than 20% motile and greater than 5% progressively motile sperm were collected. A lyophilized extender (a modified egg yolk-Tes-Tris-fructose-glycerol medium) was rehydrated and added in one step at ambient temperature (∼25 °C) to semen, which was prediluted in cell culture medium M199. After slow cooling of insulated samples to 15 °C in a refrigerator (4 °C), the samples were fast frozen over the surface of liquid nitrogen or in a dry shipper. Aliquots of 300 μL containing 20 × 10 6 sperm were frozen in cryovials and in 0.5-mL straws. Differences were observed in the total motility after thawing between vial (31.5 ± 14.1%) and straw freezing (20.1 ± 8.6%). However, the subpopulations of vital (22.7 ± 7.8% for vial and 19.8 ± 8.5% for straw) and progressively motile (10.0 ± 7.9% for vial and 10.0 ± 6.4% for straw) sperm after washing and 1 hour incubation at 38 °C were of similar magnitude, velocity, and linearity for both packaging options. After freezing of five ejaculates with 20, 60, and 100 × 10 6 sperm per dose, best results were achieved at the lowest concentration. In general, post-thaw results were highly variable (2.2% and 56.5% total motility) and not correlated to motility or morphology of the fresh semen. To further characterize semen quality, we assessed the protective potential of seminal fluid against oxidative stress, which might be challenged on freeze thawing. The capacity of seminal fluid to reduce radicals was measured in 10 semen samples by electron spin resonance

    Gastrointestinal manifestations of disease are present in most adults with cystic fibrosis. Radiologists are familiar with the classical imaging characteristics of end-stage pulmonary disease and the radiological findings of meconium ileus in neonates. As most patients now live into adulthood, recognition of the imaging appearances of abdominal disease is important to enable prompt diagnosis and treatment. Accordingly, this article presents typical imaging appearances of the adult gastrointestinal manifestations of cystic fibrosis. Copyright (2004) Blackwell Science Pty Ltd

    Purpose: To assess the role of Gamma Knife radiosurgery (GKRS) in the treatment of nonsurgical cystic brain metastasis, and to determine predictors of response to GKRS. Methods: We reviewed a prospectively maintained database of brain metastases patients treated at our institution between 2006 and 2010. All lesions with a cystic component were identified, and volumetric analysis was done to measure percentage of cystic volume on day of treatment and consecutive follow-up MRI scans. Clinical, radiologic, and dosimetry parameters were reviewed to establish the overall response of cystic metastases to GKRS as well as identify potential predictive factors of response. Results: A total of 111 lesions in 73 patients were analyzed; 57% of lesions received prior whole-brain radiation therapy (WBRT). Lung carcinoma was the primary cancer in 51% of patients, 10% breast, 10% colorectal, 4% melanoma, and 26% other. Fifty-seven percent of the patients were recursive partitioning analysis class 1, the remainder class 2. Mean target volume was 3.3 mL (range, 0.1-23 mL). Median prescription dose was 21 Gy (range, 15-24 Gy). Local control rates were 91%, 63%, and 37% at 6, 12, and 18 months, respectively. Local control was improved in lung primary and worse in patients with prior WBRT (univariate). Only lung primary predicted local control in multivariate analysis, whereas age and tumor volume did not. Lesions with a large cystic component did not show a poorer response compared with those with a small cystic component. Conclusions: This study supports the use of GKRS in the management of nonsurgical cystic metastases, despite a traditionally perceived poorer response. Our local control rates are comparable to a matched cohort of noncystic brain metastases, and therefore the presence of a large cystic component should not deter the use of GKRS. Predictors of response included tumor subtype. Prior WBRT decreased effectiveness of SRS for local control rates.

    Full Text Available Cysts in the lung can arise due to large number of causes out of which tuberculosis is very rare, We report a case of tuberculosis in a young female presenting as a febrile illness and respiratory failure with radiological features of cystic lung disease. With treatment,fever and respiratory distress subsided and cysts in the lungs showed partial regression. We highlight the need to consider tuberculosis in the differential diagnoses of cystic lung disease under appropriate circumstances.

    Full Text Available To investigate the effects of iron (Fe and copper (Cu content on basic motility characteristics (motility, progressive motility and total antioxidant status (TAS in the bovine seminal plasma semen samples were collected from breeding bulls and used in the study. Motility analysis was carried out using the Computer Assisted Sperm Analysis (CASA system. Subsequently, the samples were centrifuged and seminal plasma was collected. Fe and Cu concentrations were determined by flame absorption spectrophotometry (FAS, TAS was analyzed by UV/VIS spectrophotometry. The analysis showed that the average concentrations of the trace elements were 39.95±0.07 μg/mL for Fe and 1.55±0.22 μg/mL for Cu. The correlation analysis revealed that both metals were positively correlated with motility (r=0.527; P<0.05 for Fe and r=0.571; P<0.05 for Cu, progressive motility (r=0.496; P<0.05 for Fe and r=0.513; P<0.05 for Cu, as well as TAS (r=0.694; P<0.01 for Cu; r=0.519; P<0.05 for Fe. Moreover, the samples were categorized in three quality groups (Excellent, Good, Moderate according to their motility values. The highest Cu and Fe concentrations together with the best antioxidant characteristics were found in samples of excellent quality, moderate quality samples were described by the lowest Fe and Cu concentration and the worst antioxidant power. This study demonstrates that Cu and Fe are important for the preservation of sperm motility and antioxidant power, however this property is bound to their physiological amounts only.

    Full Text Available In order to determine the profile of leptin and insulin values in seminal plasma and their correlations with sperm patterns during the peripuberty, a total of 16 crossbred Gyr dairy bulls were monitored from 60 days before to 60 days after puberty, separated into two groups, early and regular, according to the onset of puberty. Hormone values were determined by radioimmunoassay after gel filtration in fast performance liquid chromatography and semen patterns, according to the Brazilian College of Animal Reproduction. Insulin concentrations in seminal plasma did not differ between groups, nor between the ages, with the pooling of the data showing average of 35.15±16.93, 36.60±26.21, 26.82±09.81, and 43.56±31.71 32.24±16.71 U/mL for the pubertal period of -60, -30, 0, +30 and +60 days, respectively. These values were not correlated with sperm parameters, but differed in the group of animals with the highest percentage of major defects (31.08±18.58 U/mL compared with those with lower percentage of these sperm defects (40.01±25.37 U/mL. Leptin was not correlated with sperm parameters and did not differ between groups or stage of sexual development, with concentrations of 23.10±10.43, 24.35±9.42, 22.41±9.90, 23.76±9.69 and 24.99±11.42 ng/mL for the periods of puberty aforementioned, respectively, after being grouped. These results demonstrated the binding of insulin to the structural quality of the sperm cell, and this hormone is indicated in andrologycal evaluation of future breeding soundness.

    The copulating plug collected from the tip of the penis from rats immediately after decapitation contains a protein very similar and probably identical to PSP (prostatic secretion protein); this protein has earlier been purified from rat prostatic cytosol and characterized. The protein present in the copulating plug interacts with [3H]estramustine and binds to the antibody raised against rat PSP. The concentration of the protein in the copulating plug is 400 ng/mg of total protein, when measured using the radioimmunoassay technique developed earlier for measurement of PSP in rat prostate. The [3H]estramustine-protein complex formed in a preparation of the copulating plug has an apparent molecular weight of about 50,000 and a sedimentation coefficient of about 3S when analyzed using sucrose density gradient centrifugation. The complex was retained on Concanavalin-A Sepharose indicating that the protein is a glycoprotein. Binding of the complex was also observed on hydroxylapatite and DEAE-Sephadex columns, from which it was eluted at 0.18 M KCl. Light microscope autoradiograms of rat sperms incubated with 125I-labeled PSP indicated that PSP is bound to all parts of the sperms. A macromolecule interacting with the PSP-antibodies is also present in human seminal fluid but at a concentration considerably lower than in rat seminal fluid. The present study shows that a macromolecule probably identical to prostatic secretion protein is present in the copulating plug from the rat. The biological role of this protein in normal male fertility is discussed
