  1. 1. Paediatric surgical care in Sweden. Studies on incidence, outcome and access

    Författare :Erik Omling; Lund Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PUBLIC HEALTH; Surgery; Paediatric surgery; Access to care; Quality of care; Epidemiological studies; Appendicitis; Cryptorchidism; Centralisation;

    Sammanfattning : Abstract Background: Advanced paediatric surgery is increasingly centralised in Sweden in order to improve treatment outcomes and reduce surgical risks. However, the overall need for surgery in the paediatric population has not been estimated, and the association between geographic access to surgical facilities and timely treatment for common surgical conditions in children is largely unknown.

  3. 2. The impact of genetic, environmental and life-style factors on male reproductive function

    Författare :Jonas Richthoff; Malmö Reproduktionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; male reproductive function; testicular cancer; smoking; Medicin människa och djur ; Medicine human and vertebrates ; cryptorchidism; sperm concentration;

    Sammanfattning : Recent studies have indicated a decline in sperm number in the western world during the past 50 years, sperm concentration changing from 113 to 66 millions per mL. Furthermore, significant geographical differences in male reproductive function have been observed. LÄS MER

  4. 3. A prospective randomized study of congenital cryptorchidism

    Författare :Claude Kollin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Cryptorchidism is the most common anomaly in newborn boys. Despite its frequency there are controversies regarding many aspects, including the optimal timing of surgery, natural course of the spontaneously descended testes, frequency of acquired cryptorchidism, risk of infertility and testicular cancer.

  5. 4. Etiological insights into the testicular cancer epidemic

    Författare :Olof Akre; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Testicular neoplasms; seminoma; nonseminoma; epidemiology; etiology; risk factors; prenatal; fertility; birth weight; placenta; neonatal jaundice; cryptorchidism; hypospadias; preterm birth; Epstein-Barr virus; cytomegalovirus; Body Mass Index; height;

    Sammanfattning : The aim of this thesis was to search for causes of the testicular cancer epidemic through epidemiologic studies of testicular cancer and possibly related conditions, such as urogenital birth defects and subfertility. First, we assessed changes in fertility over time by studying time-to-pregnancy among primiparous women in Sweden from 1983 through 1993 using data from the Medical Birth Registry. LÄS MER

  7. 5. Male Subfertility and Prostate Cancer Risk: Epidemiological and Genetic Studies

    Författare :Yasir Ruhayel; Malmö Molekylärgenetisk reproduktionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cytoplasmic and nuclear; Receptors; Prostatic neoplasms; genetic; Polymorphism; male; Infertility; Hypogonadism; Genetic association studies; Case–control studies; Androgens;

    Sammanfattning : Androgen action plays a pivotal role in male reproductive tract physiology and pathology. The androgen receptor (AR) gene harbors two codon repeat tracts: the CAG and GGN repeats, encoding corresponding amino acid sequences of variable length; the polyglutamine and polyglycine stretches, respectively.
