A comparison of the academic impact of plastic surgery units in the United Kingdom and Ireland using bibliometric analysis

Academic output is just one aspect of a successful career as a plastic surgeon. However, for those with a strong interest in academia, the academic output of a department will likely be a key factor when deciding how to rank jobs. The aim of this study was to quantify and rank the academic output of plastic surgery units across the UK and Ireland. The Institute for Scientific Information (ISI) Web of Science Bibliometric analysis tool was used to collate cumulative (1950–2016), 10 year (2006–2016) and 3 years (2013–2015) research output data for plastic surgery units in the UK and Ireland. Sixty-six plastic surgery units were identified. Departments were ranked for each time period according to the number of papers produced, number of citations (Nc) and h-index (a measure of the impact of scientific output). The top 3 departments for number of papers in the last 10 years were The Royal Free Hospital, London (226) Broomfield Hospital, Chelmsford (218), and Morriston Hospital and Swansea (188). The top 3 for h-number were The Royal Free Hospital (21) Wythenshawe Hospital, Manchester (18) and Morriston Hospital (17). Academic output varies across plastic surgery units in the UK and Ireland. A number of departments have consistently maintained high academic outputs across the years and will be of interest to surgeons hoping to pursue a career in academia.     

Blur adaptation: clinical and refractive considerations

The human visual system is amenable to a number of adaptive processes; one such process, or collection of processes, is the adaptation to blur. Blur adaptation can be observed as an improvement in vision under degraded conditions, and these changes occur relatively rapidly following exposure to blur. The potential important future directions of this research area and the clinical implications of blur adaptation are discussed.     

Mucinous adenocarcinoma arising from chronic perianal fistula

Perianal mucinous adenocarcinoma is a rare tumour which may be associated with long‐standing chronic perianal sepsis. Early diagnosis is challenging and is based on a high index of clinical suspicion and specific histological features. Definitive treatment is surgical, in the form of an abdomino‐perineal resection. We hereby describe a case of a perianal mucinous adenocarcinoma arising from long‐standing recurrent perianal fistula and complement this with a brief review of the literature pertaining in particular to the management of this condition.     

Validity and reliability of the Bengali version of the Hepatitis Quality of Life Questionnaire

Purpose  

Hepatitis B virus (HBV) is endemic in Bangladesh, and the quality of life (QoL) of these patients remains unknown as there is no instrument available in the native language. In this study, we translated the 56-item Hepatitis Quality of Life Questionnaire (HQLQ) into Bengali and evaluated its validity and reliability.     

Presentation and outcome of Marfan's syndrome patients with dissection and thoraco-abdominal aortic aneurysm.

BACKGROUND: In Marfan's syndrome, there is a paucity of data regarding intervention criteria for surgery of the dissected thoraco-abdominal aorta. METHODS: A retrospective analysis of 22 Marfan's patients with distal aortic dissection managed between September 1999 and April 2006 was performed. Serial diameters and linear expansion rates were calculated from imaging studies and the outcome of intervention was analysed. RESULTS: There were 14/22 male patients (median age 38 years), and 18 had prior aortic surgery. Surgery was recommended in 20 patients and undertaken in 19 (1 died prior to operation). Of the operated patients, 2 presented with rupture, 2 with airway obstruction, 1 with intermittent paraplegia and 14 underwent planned surgery for increased expansion rate or pain. All patients had residual type A or chronic type B dissection. The median aortic dimension at surgery was 6.7 cm (interquartile range (IQR) 5.5-8.2). The preoperative mean expansion rate increased from 0.5 cm/year to 1.7 cm/year (p<0.001), prior to operation. Fifteen patients underwent Crawford Extent II, two underwent Extent I and two underwent Extent III repair. Profound hypothermia and CSF drainage was used in 16 and 18 patients, respectively. There was no early mortality, paraplegia or renal failure. At a median postoperative follow-up of 56 months (range 6-86), the survival of the operated cohort was 90%. CONCLUSIONS: Thoraco-abdominal aortic aneurysm repair in Marfan's syndrome can be performed with good outcomes. Intervention should be based on size or accelerated expansion. Any role of endovascular management needs careful consideration.     

Workers' sleep quality as determined by shift system and demographic factors

The present paper is based on the results of a study conducted to examine whether there are any differences in sleep quality between permanent day workers and rotating shift workers working under two- and three-shift systems. Influences of demographic variables such as subjects' age and experience on sleep were also explored. The subjects studied consisted of 125 permanent day workers, 125 fortnightly rotating two-shift workers, and 50 weekly rotating three-shift workers. The method of data collection was that of field study through questionnaire. The results show that, compared to the permanent day workers, sleep quality is poorer for the rotating shift workers and, between the two groups of shift workers, it is poorer for the three-shift workers. These findings imply that a discontinuous two-shift system (without night work) is more convenient than a continuous three-shift system (including night work).     

Aging: changes in distribution of diazepam and metabolites in the rat

The brain levels of diazepam and its metabolites after a single iv injection of diazepam were measured over a 2-hr time period in young (3-4-month-old), mature (12-15-month-old), and senescent (29-31-month-old) male Fischer 344 rats. The areas under the brain level time curves were used as an index of exposure. Senescent rats were exposed to significantly more diazepam, N-desmethyldiazepam, and oxydiazepam between 0 and 120 min after an injection of 180 micrograms/kg of diazepam than the young or mature animals. The unbound plasma level failed to adequately account for the age-related increase in brain exposure to diazepam. Mechanisms other than the unbound diazepam in plasma are probably involved in eliciting the age-associated increase in brain levels of diazepam and its metabolites.
