Abstract Aim Epidemiological studies of deoxyribonucleic acid ( DNA ) methylation in airway disease have largely been conducted using blood or buccal samples. However, given tissue specificity methylation, these surrogate tissues may not allow reliable inferences about the lung. We sought to compare pattern blood, and nasal epithelial cells that from children. Methods Samples buccal, epithelium were obtained six children undergoing elective anaesthesia for adenotonsillectomy. was assessed at...
Abstract Objective To review the management of temporal bone fractures at a major trauma centre and introduce an evidence-based protocol. Methods A reports head computed tomography performed for from January 2012 to July 2018 was conducted. Recorded data fields included: mode trauma, patient age, associated intracranial injury, mortality, fracture pattern, symptoms intervention. Results Of 815 cases, records 165 patients met inclusion criteria; detailed analysis on these patients. Conclusion...
Evidence for the management of acute otitis externa (AOE) is limited, with unclear diagnostic criteria and variably reported outcome measures that may not reflect key stakeholder priorities. We aimed to develop 1) a definition, 2) 3) core set (COS) AOE.COS development according Core Outcome Measures in Effectiveness Trials (COMET) methodology parallel consensus selection criteria/definition.Stakeholders from United Kingdom.Comprehensive literature review identified candidate items COS,...
Abstract Background Epistaxis can be life-threatening. Simple first aid management stem bleeding. This study compared knowledge of methods epistaxis between the general public and healthcare workers. Method A cross-sectional 100 workers 103 adult members was conducted at a large London teaching hospital. Respondents completed survey assessing on nasal pinching site, head tilt appropriate adjunct treatment use for epistaxis. Results Twenty-four per cent 68 with 25.2 37.9 answered correctly...
ABSTRACT In the period May 1991 to April 1992 Ranger Oil (U.K.) Ltd., drilled five separate wells close salt diapir structures in Central Graben area of North Sea. Two different diapirs were appraised, one block 23/27 and other straddling blocks 29/2a 22/27a. Without exception all exceeded their planned dry hole drilling time estimates. addition two geological sidetracks, there three further unplanned mechanical caused by unstable conditions. A breakdown non-productive associated with is...
ABSTRACT During the 1980's exploration activity in North Sea turned towards deep, high pressure, Jurassic gas condensate reservoirs. These reservoirs occur at 16 – 18,000 ft, are abnormally pressured with pore pressures of approximately 15,500 psi, and temperatures approaching 400 deg F. This presented a new challenge to drilling industry which required development techniques, equipment philosophies. By 1985 considerable experience had been gained testing these wells. In mid Ranger Oil...
Summary Significant quantities of hydrocarbon reserves are contained in North Sea high-temperature, high-pressure (HTHP) reservoirs. De-velopment these will require deviated wells. This paper outlines the planning, drilling, and testing first HTHP well U.K. sector Sea.
ABSTRACT Critical aspects of the well design, notably, casing design are reviewed in relation to drilling well. The role pore pressure prediction and relevance kick tolerance is discussed. Problems associated with situations where pressure, mud weight fracture converge It concluded that control crucial different weights may be required for tripping. criteria led an integrated 20,000 psi system a Central Graben area North Sea reviewed. problems designing incorporating dual 15,000/20,000...

Introduction: Large primary middle cranial fossa tumors that extend into the spheno-ethmoido-clival regions and infratemporal often require combined approaches may be performed at same sitting or in staged procedures. We applied a low pterional approach with zygomatic arch osteotomy midfacial degloving to large, predominantly right-sided skull base meningioma threatened contralateral vision. This unique surgical was used successfully debulk massive originating from right sphenoid wing...
Abstract The Niger Delta is a prolific oil and gas province with almost 160 oilfields 1,500 wells put on production since the 1960s. Many of these have been producing for decades now find themselves in hands new operating companies limited resources. There are strong commercial drivers to keep through rapidly planned workover operations. historical records poor many instances nonexistent, often being no more than very simplistic A4 completion diagram lacking details summary. basis design...
Granular myringitis is a chronic and difficult-to-treat condition of the tympanic membrane. This paper presents minimally invasive treatment technique using potassium titanyl phosphate laser.A retrospective case review patients who underwent laser between 2015 2020 was performed. All final telephone follow up in to ascertain whether they had any ongoing symptoms, all were offered further face-to-face up.Fourteen with identified, one patient having both ears affected. Of 15 affected ears, 2...
