Childhood eczema is a common condition that can have a substantial impact on quality of life for children and their families. Clinical guidelines recommend that total emollient therapy forms the main treatment with emollients applied by three ways, leave on creams, soap substitutes and bath emollients. There is evidence for the effectiveness of leave on emollients and clinical consensus on the use of soap substitutes, but uncertainty exists about the effectiveness of bath emollients with a lack of reliable evidence. Despite this lack of evidence, bath additives are widely prescribed at a cost of £23m per annum in the NHS in England.

The present trial was a pragmatic, multicentre, open-label parallel group design comparing emollient bath additives in addition to standard eczema care with standard care alone on childhood eczema. Participants were recruited from 96 general practices in Wales and England and eligible children were aged 1-11 years and excluded children with inactive or very mild eczema and who bathed less than once per week. Participants in the intervention group were prescribed bath additives and asked to use them regularly for 12 months. The control group were asked not to use bath additives for 12 months. The primary outcome was eczema severity measured by the patient oriented eczema measure (POEM) reported by parents or carers weekly over 16 weeks.

A total of 12,504 letters of invitation were sent to parents or carers and 1,451 responses were received. Overall, 662 met the eligibility criteria and were approached to participate and a total of 483 entered the trial. One participant subsequently withdrew giving a total randomised of 482 participants, comprising 264 participants in the intervention arm and 218 in the control arm. The groups were well balanced on a range of baseline characteristics. By contrast, the groups were clearly different according to bath additive use with 93% of participants in the intervention arm using bath additives all of the time or more than half of the time and in the control arm 92% of participants never used bath additives or used them less than half of the time.

The baseline POEM score was 9.5 (SD 5.7) in the bath additives group and 10.1 (SD 5.8) in the no bath additives group (POEM score range 0-28, the higher the score the more severe the eczema). The mean POEM score over the 16 week period was 7.5 (SD 6.0) in the bath additives group and 8.4 (SD 6.0) in the no bath additives group. No statistically significant difference was found in weekly POEM scores between the two groups over the 16 week period. In addition, no significant differences were seen between the groups for a range of secondary outcomes, including number of eczema exacerbations, or prescribing of flare up medication.

The authors conclude that the trial provides strong evidence that emollient bath additives provide minimal or no additional benefit beyond standard eczema care in the management of eczema in children.

Shoulder pain is common and subacromial decompression for subacromial shoulder pain is one of the commonest surgical procedures in orthopaedics. Despite a lack of reliable evidence for its effectiveness, the number of patients undergoing subacromial decompression has substantially increased in recent years; in 2000 around 2,500 patients in the UK underwent subacromial decompression and by 2010 this had increased to more than 21,000.

The present trial was a multicentre, randomised, pragmatic, parallel group, placebo controlled, three group trial at 30 hospital sites in the UK. The intervention arm was arthroscopic subacromial compression. The placebo surgical intervention was investigational arthroscopy only where no bone and tissue were removed. The third arm was a no treatment arm. Patients in the surgical arms were masked to their treatment assignment, but patients in the no treatment arm were unblinded. Blinded outcome assessment was done in all groups.

Eligible participants had to have subacromial shoulder pain of at least 3 months duration with intact rotator cuff tendons, be eligible for arthroscopic surgery, and to have previously completed a non-surgical management programme that included both exercise therapy and at least one steroid injection. The primary outcome measure was the Oxford Shoulder Score (a patient reported questionnaire and an effective measure of change in pain and function in shoulders over time) at 6 months. The main analysis was according to intention-to-treat.

A total of 313 participants were randomised comprising 106 patients to decompression surgery, 103 assigned to arthroscopy and 104 assigned to no treatment. At 6 months, data for the Oxford Shoulder Score were available for 90 patients assigned to decompression, 94 to arthroscopy, and 90 to no treatment. Mean Oxford Shoulder Score did not differ between the two surgical groups at 6 months (decompression 32·7 points [SD 11·6] vs arthroscopy 34·2 points [9·2]; mean difference −1·3 points (95% CI −3·9 to 1·3, p=0·3141). Both surgical groups showed a small benefit over no treatment (mean 29·4 points [SD 11·9], decompression was higher by 2·8 points [95% CI 0·5–5·2], p=0·0186; mean difference vs arthroscopy by 4·2 points [1·8–6·6], p=0·0014) but these differences were not clinically important. A range of secondary outcomes, comprising further shoulder pain scales and more general quality of life, showed the same pattern of results as the primary outcome.

In conclusion, the authors state that in patients with persistent subacromial shoulder pain due to impingement, improvement in Oxford Shoulder Scores with arthroscopic subacromial decompression did not differ to that achieved with arthroscopy only (placebo surgery). Although both types of surgery provide greater symptom improvement than no treatment, this difference was of uncertain clinical significance. The difference between surgery and no treatment might be due to a surgical placebo effect, or possibly caused by other factors, including rest and/or post-operative physiotherapy. There were also no differences in outcome between the two surgical groups at any time point. This finding suggests that the treatment effect is not due to the principal clinical justification for the surgery, which is the removal of bone, bursa, and soft tissue to relieve impingement on the underlying tendons during movement of the arm.

Hypertension is a leading risk factor for cardiovascular disease. Despite effective medication the management of hypertension in primary remains suboptimal. Previous studies of self-monitoring, where patients monitor their own blood pressure and report back to their GP, have shown contradictory results in terms of effectiveness. The present trial aimed to assess the efficacy of self-monitored blood pressure, with or without telemonitoring, for antihypertensive titration in primary care, compared with usual care.

The design of the trial was a three-arm parallel group with self-monitoring, with or without telemonitoring and compared to usual care. Eligible hypertensive patients were older than 35, with a blood pressure higher than 140/90 mm Hg and willing to self-monitor their blood pressure. The trial duration was 12 months.

Participants randomly assigned to self-monitoring were taught to use a validated automated electronic sphygmomanometer (Omron M10-IT). They were asked to monitor their own blood pressure in their non-dominant arm, twice each morning and evening, for the first week of every month using standard recommendations and their GPs were asked to use the self-monitored measurements for titration of antihypertensive medication. A simple colour chart was used to train participants to attend their practice for a blood pressure check as a result of very high or very low readings. At the end of each monitoring week they were asked to record their readings on paper and send them for review to their practice in a reply-paid envelope.

Participants in the telemonitoring group were asked to send their results via a simple SMS text service. The telemonitoring system incorporated an algorithm that alerted participants to contact their surgery in the light of very high or very low readings, reminded them if insufficient readings were transmitted, prompted them to make contact with their practice if their average blood pressure was above target, and presented readings to attending clinicians via a web interface. This secure web page automatically calculated mean blood pressure for each monitoring week, highlighted very high or very low readings, and presented a graphical display of blood pressure measurements.

General practitioners were asked to review both self-monitoring and telemonitoring groups’ readings on a monthly basis and usual care patients as often as they wished. Blood pressure targets were based on current National Guidelines adjusted for self-monitoring: lower than 140/90 mm Hg (<135/85 mm Hg at home) for those younger than 80 years, lower than 150/90 mm Hg (<145/85 mm Hg at home) for those 80 years or older, and lower than 140/80 mm Hg (<135/75 mm Hg at home) for those with diabetes.

A total of 142 general practices participated recruiting a total of 1182 participants, of which 1003 (85%) were included in the primary analysis.

Systolic blood pressure at baseline was around 153 mm Hg in all groups and at 12 months the blood pressure was lower in all of the groups, with the largest reduction seen in the self-monitoring and telemonitoring groups: blood pressure at 12 months, usual care group 140.4 (SD 16.5, n=348), self-monitoring group 137.0 (16.7, n=328), telemonitoring group 136.0 (16.1, n=327). At 12 months, the adjusted mean difference in systolic blood pressure compared to usual care was significantly lower for both the self-monitoring (-3.5 [95% CI -5.8 to -1.2] p=0.0029) and telemonitoring (-4.7 [-7.0 to -2.4] p<0.0001) groups. There was no difference in the adjusted mean difference between the self-monitoring and telemonitoring groups (-1.2 [-.3.5 to 1.2] p=0.3219).

After 12 months, the number of prescribed antihypertensives was higher in the self-monitoring (1.63 [SD 0.89]) and telemonitoring groups (1.70 [0.88]) compared to the usual care group (1.55 [0.85]). The adjusted mean difference was significantly higher in both the self-monitoring group (0.11 [95% CI 0.02 to 0.19] p=0.0129) and telemonitoring group (0.13 [0.04 to 0.21] p=0.0038) compared to the usual care group.

The authors conclude that after one year patients whose medication was adjusted using self-monitoring, with or without telemonitoring, has significantly lower systolic blood pressure than those receiving treatment adjusted using clinic blood pressure.

Children with persistent hearing loss due to otitis media with effusion are commonly managed by surgical intervention. A Cochrane review indicated that oral steroids might provide some short term benefit, but the studies included were underpowered and poor quality. The present randomised trial was undertaken to determine whether oral steroids improved hearing in children with hearing loss from otitis media with effusion.

Eligible children were those aged 2–8 years with symptoms of hearing loss attributable to otitis media with effusion for at least 3 months. The trial was double-blind with children randomised 1:1 to either a one week course of oral prednisolone or matching placebo. The primary outcome was acceptable hearing at 5 weeks with further follow-up at 6 and 12 months. Secondary outcomes included adverse events and quality of life. All analyses were intention to treat.

A total of 1,018 children were assessed for eligibility and of these 389 (38%) from 20 sites were randomly assigned. The majority of those excluded did not meet the inclusion criteria. After randomisation, a further 9 children were excluded (6 of them due to the hearing test result not meeting the pre-specified threshold and in a further 3 where consent was withdrawn). A total of 380 children (193 children in the steroid group and 187 in the placebo group) were included in the analyses.

Hearing at 5 weeks was assessed in 183 children in the oral steroid group and 180 in the placebo group. Acceptable hearing was observed in 73 (40%) children in the oral steroid group and in 59 (33%) in the placebo group (absolute difference 7% [95% CI −3 to 17]; the adjusted odds ratio was 1·36 [95% CI 0·88–2·11]; p=0·16). No significant differences were also observed in secondary outcomes for adverse events and for quality of life.

The authors conclude that a short course of oral steroids for otitis media with effusion is unlikely to be effective for most children aged 2–8 years.

The consumption of contaminated water, inadequate sanitation and hygiene are the main contributors to an estimated four billion cases of diarrhea every year, causing 1.8 million deaths, out of which about 90% are children under 5 years of age. In Ethiopia, nearly 40 million people, mostly in rural areas, do not have access to safe drinking water and 90% of households do not treat their drinking water at home. Studies conducted in different parts of Ethiopia indicated that a 2-week prevalence of diarrhea among under-five children ranged from 23 to 31%.

The installation of large-scale water treatment plants in rural Ethiopia is difficult due to the scarcity of resources and scattered settlement. Therefore, low-cost home water treatment kits have been proposed as a potential solution in rural areas. One home based water treatment is solar water disinfection where raw water is filled into polyethylene terephthalate (PET) bottles and relies on the germicidal effects of sunlight and heat.

The study was conducted in Dabat district, northwest Ethiopia. The study area was divided into an intervention area using solar disinfection of water and a control area separated by a buffer zone to avoid contamination of information. Clusters were chosen by randomly selecting 14 villages from within each of the intervention and control study areas.

A total of 397 under five children in 280 households in the intervention and 400 under fives in 293 households in the control group were enrolled in 28 clusters (villages). The baseline analysis compared the socio-demographic and economic factors and there were no significant differences between the two groups. Water analysis showed similar high rates of contamination of raw water in both groups. During the baseline period, a 2-week prevalence of diarrhea was 20.8% (80/384) in the intervention and 21.8% (86/394) in the control groups was recorded.

During the active intervention phase, there were significantly fewer cases of diarrhea, i.e., 8.3 episodes per 100 person-week observations (378 episodes of diarrhea) among under fives in the solar disinfection intervention group and 15.3 episodes of diarrhea per 100 person-week observations (720 episodes of diarrhea) in the control during the entire 6-month consecutive follow-up. The overall prevention of diarrheal incidence among under fives during the 6 month solar disinfection intervention was 40% (95% CI 30–48) compared to the control group.
