Anatomic Anomalies of the Nerves Treated during Headache Surgery.

Background: Headache surgery is a well-established, viable option for patients with chronic head pain/migraines refractory to conventional treatment modalities. These operations involve any number of seven primary nerves. In the occipital region, the surgical targets are the greater, lesser, and third occipital nerves.

The features and processes underpinning high-quality data generation in participatory research and engagement activities.

Participatory approaches are widely used by researchers to gather data and insight about how the environment is perceived, valued and used. The participatory activities may be creating information as part of curiosity-driven blue-skies research or to inform policy/practise decision-making.The quality and usability of data derived from participatory approaches are heavily influenced by how activities are conducted.

Nature, smells, and human wellbeing.

The link between nature and human wellbeing is well established. However, few studies go beyond considering the visual and auditory underpinnings of this relationship, even though engaging with nature is a multisensory experience. While research linking smell to wellbeing exists, it focuses predominantly on smells as a source of nuisance/offence.

Do ecosystem service frameworks represent people's values?

Since the Millennium Ecosystem Assessment was published, a plethora of ecosystem service frameworks have been developed to conceptualise the links between the natural environment and society. The intended geographic scales of application, the policy/practice context, and the scientific disciplines involved have driven variations in how the frameworks are constructed. However, the frameworks are homogenous in that they have been created predominately based on expert opinions and views of how ecosystem services are structured.

Species identification by conservation practitioners using online images: accuracy and agreement between experts.

Emerging technologies have led to an increase in species observations being recorded via digital images. Such visual records are easily shared, and are often uploaded to online communities when help is required to identify or validate species. Although this is common practice, little is known about the accuracy of species identification from such images.

Discordance in investigator-reported and adjudicated sudden death in TIOSPIR.

Accurate and consistent determination of cause of death is challenging in chronic obstructive pulmonary disease (COPD) patients. TIOSPIR (N=17 135) compared the safety and efficacy of tiotropium Respimat 5/2.5 µg with HandiHaler 18 µg in COPD patients.

Species identification by experts and non-experts: comparing images from field guides.

Accurate species identification is fundamental when recording ecological data. However, the ability to correctly identify organisms visually is rarely questioned. We investigated how experts and non-experts compared in the identification of bumblebees, a group of insects of considerable conservation concern.

Higher lung deposition with Respimat Soft Mist inhaler than HFA-MDI in COPD patients with poor technique.

Aerosols delivered by Respimat Soft Mist Inhaler (SMI) are slower-moving and longer-lasting than those from pressurized metered-dose inhalers (pMDIs), improving the efficiency of pulmonary drug delivery to patients. In this four-way cross-over study, adults with chronic obstructive pulmonary disease (COPD) and with poor pMDI technique received radiolabelled Berodual (fenoterol hydrobromide 50 microg/ipratropium bromide 20 microg) via Respimat SMI or hydrofluoroalkane (HFA)-MDI (randomized order) on test days 1 and 2, with no inhaler technique training. The procedure was repeated on test days 3 and 4 after training.

Videoconferencing: what are the benefits for dental practice?

For more than 3 years members of the TeleDent team from Bristol University have been looking at the potential of videoconferencing technology for dentistry. Here they explain what videoconferencing is and how it can help the GDP. They discuss examples of its most promising uses for the profession, which include professional updating and providing diagnostic support at a distance.

Urologic complications of hip arthroplasty.

Significant intrapelvic injuries from routine hip surgery are rare but may result in long-term urologic morbidity. Two illustrative cases are presented with attention given to the close anatomic proximity of the intrapelvic structures to the hip joint and their potential for injury after hip surgery. A review of similar cases with their management is presented.

Morphology and pathogenesis of adrenal cysts.

Adrenal cysts represent a rare condition (approximately 250 cases have been reported). We report two additional cases: the first involved a huge lesion removed surgically and thoroughly studied preoperatively; the second was an incidental autopsy finding. Detailed ultrastructural studies have been made of both cases.

Penile carcinoma in renal transplant recipient.

A case of squamous cell carcinoma of the penis occurring in a renal transplant recipient is presented. Despite a markedly increased incidence of epidermoid carcinoma in the transplant population, this is the first reported case of penile carcinoma occurring in a renal transplant recipient. As with other superficial epithelial tumors in this population, conventional therapeutic techniques are recommended.

Management of prostatic fistulas.

Prostatic fistulas communicating with the rectum or perineal skin are unusual complications of a prostatic operation, pelvic trauma, prostatic abscess or other iatrogenic injury. A third of these fistulas may close spontaneously with proper urinary drainage and avoidance of fecal soilage. The many operative procedures described for the repair of these fistulas indicate that no ideal method of repair can be applied to every case.

Metastatic infection secondary to genitourinary tract sepsis.

Metastatic infections arising from sepsis in the genitourinary tract are reviewed in 175 cases, including five in which we treated the patients. The skeleton was the most common site of metastasis (59 per cent). The endocardium was next most frequently involved (28 per cent).
