Spots, Sleep and Staying Strong

This edition starts with skin, strength and a reminder that good care often means doing the basics well.

NICE’s acne guidance is pleasingly practical: match treatment to severity, use combination topical therapy for most people, avoid antibiotic monotherapy, and review after 12 weeks. It also rightly recognises that acne can cause real psychological distress, whatever its clinical severity.

In infant eczema, pimecrolimus and low- to medium-potency topical corticosteroids appear similarly effective and safe for mild to moderate disease. The less glamorous but useful message: topical steroids remain familiar, effective and much cheaper.

Frailty brings the biggest-picture lesson. The Australian consensus statement recommends proactive, personalised care: annual screening from 65, protein-rich nutrition, progressive exercise, social prescribing, medication review, and care planning aligned with the person’s goals.

Elsewhere, “less can be more” appears repeatedly: deprescribing PPIs can work better when both patient and GP are nudged; structured support can help opioid tapering; testosterone is not clearly useful without confirmed hypogonadism; and CBT-I remains the insomnia treatment to beat.

The theme this week? Treat early, review properly, avoid unnecessary medicines and tests, and never underestimate the value of a clear plan.

NICE

How should acne vulgaris be managed in primary and specialist care?

Clinical bottom line: Acne should be treated according to severity, with 12-week courses of combination topical therapy for most people and oral antibiotics added for moderate–severe acne when appropriate. Avoid antibiotic monotherapy, review treatment at 12 weeks, and refer urgently for acne fulminans or specialist input for severe, scarring, refractory, or psychologically distressing acne.

Brief summary: This NICE guideline covers acne care from skin advice to specialist treatment. It recommends gentle non-comedogenic skin care, no specific acne diet, and first-line combinations such as adapalene–benzoyl peroxide, tretinoin–clindamycin, or benzoyl peroxide–clindamycin. For moderate–severe acne, topical treatment plus doxycycline or lymecycline is recommended. Oral isotretinoin is reserved for severe acne resistant to adequate standard therapy, with pregnancy prevention and mental health monitoring.

In infants under 2 years with eczema, how effective and safe are topical treatments?

Clinical bottom line: In mild–moderate infant eczema, pimecrolimus and low- to medium-potency topical corticosteroids appear similarly effective, with similar short- and long-term safety. Steroids are much cheaper.

Brief summary: Pimecrolimus was better than vehicle in one RCT. In a large 5-year trial, pimecrolimus and topical corticosteroids produced similar clearance rates and adverse-event withdrawals. Evidence for steroid harms in children is generally reassuring when used intermittently and appropriately.

Australian Consensus Statement

How should frailty be prevented and managed in community-dwelling older adults?

Clinical bottom line: Frailty should be managed proactively using annual screening from age 65, personalised lifestyle counselling, protein-rich nutrition, progressive exercise, social prescribing, medication review, and person-centred care planning—especially in severe frailty. Evidence is partly consensus-based, but strongly supports a multidisciplinary, individualised approach.

Brief summary: This Australian consensus statement recommends integrated community frailty care across six areas: health promotion/screening, nutrition, exercise, social prescribing, medicines optimisation, and severe frailty management. Key actions include identifying frailty early, treating malnutrition and deficiencies, combining aerobic/resistance/balance training, supporting meaningful social engagement, reviewing medicines to reduce harm, and aligning severe-frailty care with patient goals, carers, advance care planning, and end-of-life preferences.

Should adults with chronic insomnia receive CBT-I plus medication, rather than either treatment alone?

Clinical bottom line: CBT-I remains the preferred first-line treatment. Adding medication is better than medication alone, but does not appear better than CBT-I alone, except possibly when rapid improvement in total sleep time is a high priority. Evidence certainty is low.

Brief summary: This AASM guideline suggests CBT-I plus insomnia medication over medication alone, but suggests against combination treatment over CBT-I alone. Combination treatment may modestly improve early sleep duration, but offers no clear added benefit for overall insomnia severity, sleep continuity, or daytime symptoms compared with CBT-I alone. Treatment choice should reflect patient priorities, access to CBT-I, costs, and medication risks.

Can a patient- and GP-facing deprescribing intervention reduce long-term proton pump inhibitor use in primary care?

Clinical bottom line: A simple deprescribing intervention sent to both patients and GPs roughly doubled the proportion of long-term PPI users achieving at least a 50% dose reduction, without worsening reflux symptoms.

Brief summary: In this large French cluster RCT, 34,409 long-term PPI users were allocated to usual care, GP-only deprescribing advice, or combined patient and GP deprescribing support. Dose reduction occurred in 14.9% with the combined intervention versus 7.0% with usual care and 7.7% with GP-only advice. Reflux symptom scores did not differ meaningfully between groups.

Do different antihypertensive drug classes affect incident dementia risk in older adults?

Clinical bottom line: Antihypertensive treatment may modestly improve cognitive scores in older adults with hypertension, but evidence that it reduces incident dementia is uncertain. Drug-class rankings are exploratory and should not drive prescribing.

Brief summary: This systematic review included 4 RCTs with 16,823 older adults followed for 2.0–3.9 years. Antihypertensive therapy slightly improved cognitive function but did not significantly reduce dementia incidence. Exploratory analysis suggested possible differences by drug class, but the evidence was sparse and highly uncertain. Current findings support good blood pressure control rather than choosing a specific antihypertensive solely for dementia prevention.

Can a group-based educational intervention help adults with chronic non-cancer pain reduce or stop strong opioid use?

Clinical bottom line: I-WOTCH helped substantially more people stop opioids at 12 months, without worsening pain interference. It may be cost-effective, but results apply mainly to people willing to reduce opioids.

Brief summary: In this primary-care RCT, 608 adults using strong opioids for chronic non-cancer pain received usual care or usual care plus I-WOTCH: group education, individual support, and nurse-led tapering follow-up. At 12 months, 29% in the intervention group versus 7% in usual care reported no opioid use, with no significant difference in pain interference. Opioid use was self-reported, and applicability to very high-dose or complex secondary-care patients is uncertain.

Does testosterone replacement improve sexual dysfunction in men without confirmed hypogonadism?

Clinical bottom line: In men with sexual dysfunction but no confirmed testosterone deficiency, testosterone replacement shows no clear short-term benefit over placebo, PDE5 inhibitors, or PDE5 inhibitors alone when used in combination. Long-term benefit is uncertain.

Brief summary: This review of 43 RCTs found little to no clinically important improvement in erectile function or sexual quality of life with testosterone therapy in men without known hypogonadism. Evidence for long-term outcomes and comparisons with PDE5 inhibitors was limited or very uncertain. Current guidance supports checking and confirming consistently low testosterone before considering testosterone therapy.

Which interventions safely and effectively reduce opioid use in adults with chronic non-cancer pain?

Clinical bottom line: Evidence for specific opioid tapering interventions is mixed and uncertain. Most studies found no worsening of pain, and serious harms were not reported, but tapering success varied and relapse occurred in some studies.

Brief summary: This systematic review included 44 studies of interventions to reduce or stop prescription opioids in chronic non-cancer pain. Interventions were heterogeneous, preventing meta-analysis. Across comparative studies, pain severity usually did not differ between intervention and control groups, but effects on opioid cessation, mental health, sleep, and acceptability were unclear. Successful tapering appears to depend on individual support, addressing fear and stigma, clinician skills, and attention to inequalities.

How should hemorrhoids be diagnosed and treated?

Clinical bottom line: Hemorrhoids should be diagnosed with history, examination, and ideally anoscopy before treatment. First-line management is fibre, constipation treatment, and avoiding straining; topical treatments may help symptoms but have limited evidence. For grades 1–3 hemorrhoids, office procedures such as rubber band ligation or infrared coagulation should usually be tried before surgery.

Brief summary: This AGA expert review gives best-practice advice for hemorrhoid care. Significant pain suggests thrombosis or another diagnosis such as fissure. Rubber band ligation and infrared coagulation are safe and effective office treatments, with banding offering longer-term benefit for prolapse or recurrent bleeding. Surgery is generally reserved for grade 4 disease, failed office treatment, or significant external hemorrhoids. Special caution is needed in pregnancy, active IBD, cirrhosis, and after procedures because rare pelvic sepsis can occur.

Is first-contact physical therapy better than usual primary care for musculoskeletal disorders?

Clinical bottom line: First-contact physical therapy appears to reduce imaging and prescription medication use compared with usual primary care, with little or no difference in disability or quality of life. Effects on pain and cost are uncertain.

Brief summary: This systematic review of 10 RCTs involving 2,081 patients found that first-contact physical therapy was associated with lower imaging rates and fewer prescriptions for musculoskeletal disorders. Clinical outcomes were broadly similar to usual primary care: disability and health-related quality of life showed little difference, while pain and cost estimates favoured first-contact physical therapy but were uncertain. Evidence quality ranged from very low to moderate.

Can a pelvic floor workout during pregnancy prevent postpartum stress urinary incontinence in first-time mothers?

Clinical bottom line: A structured pelvic floor workout from 28 weeks’ gestation reduced stress urinary incontinence at 6 weeks postpartum and improved pelvic floor muscle strength.

Brief summary: In this multicentre RCT of 764 primiparous women, PEFLOW plus usual care was compared with usual care alone. At 6 weeks postpartum, SUI occurred in 8.7% of the exercise group versus 13.9% of controls. More women in the exercise group also achieved higher pelvic floor strength scores. This suggests antenatal pelvic floor training can modestly reduce early postpartum SUI.

How should functional constipation in children be diagnosed and managed?

Clinical bottom line: Pediatric functional constipation should usually be diagnosed clinically, using history and examination, with tests reserved for alarm features or treatment failure. First-line care is education, diet/lifestyle advice, toilet routines, and laxatives—especially PEG—with escalation to specialist and advanced therapies only if refractory.

Brief summary: This AGA–NASPGHAN pathway provides a practical approach for primary care and pediatric gastroenterology. It recommends using Rome IV criteria as a guide, avoiding routine abdominal X-rays, treating fecal impaction before maintenance therapy, and using osmotic laxatives first line. Neurodivergent children may need tailored assessment and behavioural support. Persistent, complex, or refractory cases may need specialist referral, motility testing, transanal irrigation, ACE procedures, or structured transition to adult care.

Do weekly catheter washouts reduce blockage or infection in adults with long-term catheters?

Clinical bottom line: Weekly saline or acidic catheter washouts may reduce catheter blockages, and saline may reduce symptomatic catheter-associated UTI, but the evidence is inconclusive because the trial was stopped early and recruited only 80 participants.

Brief summary: In this UK pragmatic RCT, adults with long-term catheters were randomised to standard care, weekly saline washouts, or weekly acidic washouts. Washout groups had fewer catheter blockages requiring intervention, but differences were not statistically significant. Saline washouts reduced antibiotic-treated symptomatic catheter-associated UTI, though this finding should be interpreted cautiously. Washouts appeared acceptable and feasible for self-management after training, with few adverse events.

Are GLP-1 and dual GLP-1/GIP receptor agonists safe in preconception, pregnancy, and lactation?

Clinical bottom line: Inadvertent preconception or early-pregnancy exposure to GLP-1-based therapies has not shown a consistent signal of increased maternal, fetal, or neonatal harm, but evidence remains limited—especially for continued use during pregnancy and lactation.

Brief summary: This systematic review included 36 human studies of GLP-1 or dual GLP-1/GIP receptor agonist exposure before conception, during pregnancy, or during lactation. Observational data did not consistently show increased risks of major congenital malformations, fetal growth restriction, stillbirth, or neonatal mortality after early exposure. Maternal outcomes were mixed, and lactation evidence was sparse, though one study found no detectable semaglutide in breast milk. Continued use during pregnancy remains insufficiently studied.

Is as-needed budesonide–formoterol an effective reliever treatment for asthma?

Clinical bottom line: In adults, as-needed budesonide–formoterol reduces severe asthma exacerbations compared with SABA reliever alone and appears similar to maintenance inhaled corticosteroids for exacerbation prevention. Evidence in children is limited.

Brief summary: RCT evidence suggests budesonide–formoterol used as a reliever lowers exacerbation risk versus SABA, especially in mild asthma. Compared with regular maintenance ICS, exacerbation rates are similar, though symptom control may be slightly worse. Adverse events are similar or lower than SABA, but most trials were industry sponsored and paediatric evidence is sparse.

Which bedside tests best diagnose peripheral arterial disease in people with diabetes?

Clinical bottom line: Common bedside tests for peripheral arterial disease in people with diabetes had poor sensitivity and should not be relied on to rule out disease. Podiatry Ankle Duplex showed higher sensitivity, but was assessed only in selected centres.

Brief summary: This UK multicentre diagnostic accuracy study compared bedside tests with CT or MR angiography in adults with diabetes. PAD was present in 39% of those imaged. Sensitivity was low for audible waveform, visual waveform, toe–brachial pressure index, ankle–brachial pressure index, and exercise ankle–brachial pressure index. Podiatry Ankle Duplex performed better, but evidence was more limited.
