Introducing holmium laser enucleation of the prostate alongside transurethral resection of the prostate improves outcomes of each procedure

INTRODUCTION

Holmium laser enucleation of the prostate (HoLEP) is recognised as an alternative to transurethral resection of the prostate (TURP). HoLEP has been demonstrated to be at least as effective as TURP with less morbidity but its introduction to practice has been limited in part by the learning curve of a novel procedure. This study examined the effects of introducing HoLEP alongside an established practice of TURP on early morbidity and length of hospital stay (LOS).

METHODS

A retrospective review of all patients who underwent HoLEP and TURP between April 2007 and July 2011 was undertaken. HoLEP was introduced in April 2008; patients undergoing TURP before this were considered as a historical control group. Data were collected concerning resection/enucleation weight, blood transfusions and LOS.

RESULTS

Overall, 772 patients underwent HoLEP or TURP within the 52-month study period: 164 underwent TURP prior to the introduction of HoLEP (TURP-A), 425 had TURP after the introduction of HoLEP (TURP-B) and 183 underwent HoLEP. The mean removed weight was 24g (standard deviation [SD]: 21g) for TURP-A, 19g for TURP-B (SD: 16g) and 38g (SD: 32g) for HoLEP (p<0.005). Blood transfusion rates were 5.5%, 2.2% and 1.6% for the TURP-A, TURP-B and HoLEP groups respectively (p<0.05). For TURP-A patients, the mean LOS was 5.6 days (SD: 3.5 days, 95% confidence interval [CI]: 5.3-6.0 days). The mean LOS for TURP-B patients was 4.4 days (SD: 4.4 days, 95% CI: 4.2-4.8 days). HoLEP patients had a mean LOS of 3.0 days (SD: 3.0 days, 95% CI: 2.6-3.4 days).

CONCLUSIONS

The introduction of HoLEP alongside TURP is associated with lower rates of blood transfusion and shorter LOS for all patients. This is likely to be due to the use of HoLEP rather than TURP in patients with larger prostates, who are more likely to have complications.

Does increased sunlight exposure work as a strategy to improve vitamin D status in the elderly: a cluster randomised controlled trial

SUMMARY

Sunlight exposure by improving vitamin D status could be a simple public health strategy in reducing falls among frail elder people. In a randomised controlled trial, adherence to sunlight exposure was low (median adherence, 26%) and no effect of increased UV exposure on falls risk was observed (incidence rate ratio (IRR) 1.06, P = 0.73).

INTRODUCTION

This study aimed to determine whether increased sunlight exposure was effective to improve vitamin D status and reduce falls in the elderly.

METHODS

In a cluster randomised controlled trial (NCT00322166 at ClinicalTrials.gov), 602 residents aged 70 or more (mean age, 86.4 years; 71% female) were recruited from 51 aged care facilities in Northern Sydney, Australia. Participants were randomised by facility to receive either increased sunlight exposure (additional 30-40 min/day in the early morning) with (UV+) or without (UV) calcium supplementation (600 mg/day) or neither (control) for a year. The co-primary endpoints were change in serum 25 hydroxy vitamin D (25OHD) and falls incidence after 12 months.

RESULTS

Adherence to sunlight exposure was low (median adherence, 26%; IQR, 7%-45%). Serum 25OHD levels were low at baseline (median, 32.9 nmol/L) and increased only slightly depending on the number of sunlight sessions attended over 12 months (P = 0.04). During the study, 327 falls occurred in 111 (54%) subjects in the control group, 326 falls in 111 (58%) subjects in the UV only group and 335 falls in 108 (52%) subjects in the UV+ group. By intention-to-treat analysis, there was no significant effect of increased UV exposure on falls risk (IRR, 1.06; 95% CI, 0.76-1.48; P = 0.73). However, in 66 participants who attended ≥130 sessions per year (adherence, ≥50% of 260 sessions-five per week), falls were significantly reduced (IRR, 0.52; 95% CI, 0.31-0.88; P = 0.01) compared with the control group.

CONCLUSIONS

Increased sunlight exposure did not reduce vitamin D deficiency or falls risk in frail older people. This public health strategy was not effective most likely due to poor adherence to the intervention.

An assessment of oral health promotion programmes in the United Kingdom

BACKGROUND

Improving oral health and reducing tooth decay is a key area for action, both in the United Kingdom (UK) and overseas. The World Health Organization (WHO) has highlighted the unique advantage schools have in promoting oral health.

AIM

We summarise current oral health promotion strategies in the United Kingdom and estimate the spread of their use as well as their impact on oral health and influence on the oral health-related knowledge and behaviour in a patient population.

METHODS

A structured overview of published papers, government publications, official government websites and policy reports. A cross-sectional study of patients referred for a tooth extraction in one dental surgery in south-east London. Statistical methods consisted of logistic and ordinal regressions to model the likelihood of exposure to oral health promotion and of obtaining higher levels of knowledge of oral health issues, respectively. Linear regression was used to model the level of oral health and knowledge of oral health issues.

RESULTS

We found three main promotion programmes, namely, National Healthy Schools (NHS), Sure Start and Brushing for life plus a small number of local initiatives. Sure Start targets disadvantaged areas, but is limited. In our observational study, 34% of the patients reported exposure to a settings-based oral health education programme: Sure Start (5%), NHS (7%) and other (22%). This exposure was not influenced by age or gender, but an association with education was detected. Although oral health promotion was not found to influence the actual knowledge of oral health issues, it was found to influence some oral health-related attitudes and perceptions.

CONCLUSIONS

Participation in an oral health promotion programme was found to be significantly associated with the patients' education, their belief that they can prevent oral disease and the subjective perception of their own oral health. The WHO principles need to be embedded across all schools to achieve a true national oral health promotion programme for the United Kingdom. The National Healthy Schools programme provides the perfect platform.
