Road ecology has traditionally focused on the impact of in-situ and functional roads on wildlife. However, road construction also poses a major, yet understudied, threat and the implications for key aspects of animal behaviour are unknown. Badgers (Meles meles) have been implicated in the transmission of tuberculosis to cattle.

European badgers (Meles meles) in medium and high density populations show strong territorial behaviour. Territories in these populations are contiguous, well-marked and often unchanging over many years. However, badgers do not always stay within their territorial boundaries.

European badgers () are group-living mustelids implicated in the spread of bovine tuberculosis (TB) to cattle and act as a wildlife reservoir for the disease. In badgers, only a minority of individuals disperse from their natal social group. However, dispersal may be extremely important for the spread of TB, as dispersers could act as hubs for disease transmission.

Background: Clinician and patient factors impact on the management of chronic pelvic pain (CPP) with medical, surgical or combined approaches possible, although none have proven superior.

Aims: To understand the characteristics of women offered laparoscopic pelvic surgery for CPP.

Materials And Methods: We performed an observational study of women referred with CPP.

Background and aims Chronic pelvic pain (CPP) impacts significantly on the lives of women. Negative coping responses such as pain catastrophizing are thought to be significant in predicting both pain severity and outcome. The combined effect of the individual's response to pain and its severity on their quality of life (QoL) has not been well studied in women with CPP.

Background: In Australia, gynaecologists continue to investigate women with abnormal bleeding and suspected intrauterine pathology with inpatient hysteroscopy despite some evidence in the literature that that there is no difference in safety and outcome when compared to an outpatient procedure.

Aims: This prospective study assessed the safety, effectiveness and acceptability of outpatient hysteroscopy over 11 years at a tertiary hospital in Australia. Resource savings were then calculated.

Study Question: Can the presence of endometrial nerve fibres be used as a diagnostic test for endometriosis in women with pelvic pain?

Summary Answer: Endometrial fine nerve fibres were seen in the endometrium of women both with and without endometriosis, making their detection a poor diagnostic tool for endometriosis.

What Is Known Already: Laparoscopy and biopsy are currently the gold standard for making a diagnosis of endometriosis. It has been reported that small density nerve fibres in the functional layer of the endometrium are unique to women with endometriosis and hence nerve fibre detection could function as a less invasive diagnostic test of endometriosis.

Purpose: To determine if the menstrual cycle affects MR interpretation in patients with pelvic endometriosis.

Materials And Methods: Thirty-one patients with either laparoscopically proven endometriosis, or a high clinical suspicion of deep infiltrative endometriosis, were prospectively recruited from May 2008 to October 2009 and January to June 2012. Two pelvic MR scans were performed for pre-operative planning; during menses and the other mid-cycle.

Introduction: Over the past three decades, rates of overweight and obesity internationally have risen to epidemic proportions. There are currently no published prospective studies examining the effect of obesity on gynaecologic laparoscopy for benign indications within a population with obesity rates comparable to Australian women.

Aims: To assess and quantify whether increasing patient body mass index negatively impacted upon the ability to successfully complete planned laparoscopic surgery.

Background: Surgical treatment of deep infiltrating endometriosis (DIE) is complex, and preoperative diagnosis benefits both surgeon and patient. Studies in expert centres have reported high accuracy for transvaginal ultrasound (TVUS) diagnosis of DIE. External validation of these findings has been limited, and no information is available on how quickly these skills can be acquired.

Background: Correctly placed levonorgestrel-releasing intrauterine systems (LNG-IUSs) are rarely associated with intrauterine pregnancy when pregnancy occurs. LNG-IUS retrieval, termination of pregnancy and conservative management if retracted strings prevent ready removal are the usual clinical options given to women. The conservative course raises concerns about teratogenesis related to high local progestin exposure for the developing fetus.

Damage to the peritoneum during abdominal surgery triggers a cascade of events aimed at repairing the damage. As part of this process, fibrin is deposited, which is the precursor to the formation of an adhesion between 2 damaged peritoneal surfaces. This can have a significant impact on morbidity and even mortality as well as large cost implications.
