Background: This study evaluated the level of burden in pediatric and adolescent atopic dermatitis (AD) patients in Japan, the associated burden on caregivers/families, and whether this burden varied with age. Methods: Data were drawn from the Adelphi Pediatric AD Disease Specific Programme (DSP)™, a cross‐sectional survey of physicians and their patients conducted in Japan between July and December 2022. Physicians reported patient demographics, clinical characteristics, disease burden, and current/previous therapies. Patients and/or caregivers reported perceived disease severity and impact of AD, including the Children's Dermatology Life Quality Index (CDLQI) and Dermatitis Family Impact questionnaire (DFI). Results: Overall, 55 physicians provided data for 537 AD patients aged ≤17. Mean (SD) overall scores for CDLQI, POEM, and DFI were 9.3 (6.3), 8.3 (6.8), and 11.7 (7.2), respectively. Age was associated with higher patient and/or caregiver‐reported CDLQI scores, which increased by 0.543 points per year of age (P = 0.01). Patients with severe disease reported a more significant impact on quality of life factors compared with mild patients (P < 0.001). Age was associated with higher caregiver‐reported burden, with DFI scores increasing by 0.325 per year (P = 0.01). Physician‐reported impact on caregivers showed that age was significantly associated with increased burden on sleep, daily activities, work, and mood (P < 0.05), with disease severity associated with impact across all factors (P < 0.01). Conclusions: Both increasing age and disease severity were associated with the increased impact of AD on patients and their caregivers. Disease control/modification through appropriate therapeutic intervention at a younger age may relieve the burden of pediatric AD on patients and their families. [ABSTRACT FROM AUTHOR]

Background Buerger disease, also known as Winiwarter–Buerger disease or thromboangiitis obliterans (TAO), is a non-specific inflammation of small- and medium-sized arteries with thrombus obliteration and without atherosclerotic changes. Patients with TAO can develop chronic limb-threatening ischaemia (CLTI) and are at risk of limb amputation despite smoking cessation and exercise therapy recommendations. Case summary A 72-year-old Japanese man presented with painful discolouration of toes and renal impairment. He was diagnosed with Rutherford classification Stage 6 CLTI with immunoglobulin A nephropathy. He refused limb amputation. Clinical symptoms reduced after treatment with low-intensity pulsed ultrasound (LIPUS). LIPUS is a non-invasive option to alleviate peripheral arterial disease symptoms. Despite the initiation of conventional therapy measures, there was a worsening of the limb condition. The non-invasive investigational treatment option of LIPUS was initiated after the poor clinical outcomes of the conventional therapy measures. The patient's symptoms in the bilateral lower limbs, ulcers, and the blue-coloured toes gradually lessened. After 1 year of treatment with LIPUS, he had achieved better walking independence with improved quality of life. Discussion Low-intensity pulsed ultrasound is a non-invasive option for therapeutic angiogenesis with the potential to improve ischaemic limb conditions in patients with peripheral arterial disease and to avoid major amputation procedures.

Background: Moderate-to-severe atopic dermatitis (AD) impacts patients' quality of life (QOL). More treatment options are urgently needed to manage this chronic disease. Lebrikizumab is a monoclonal antibody that binds to IL-13, a key mediator in AD pathogenesis. In Japanese patients, lebrikizumab has been evaluated through week (W) 16 in the randomized, placebo-controlled, phase III ADhere-J study., Objectives: To evaluate long-term efficacy and safety of lebrikizumab in combination with topical corticosteroids (TCS) in the ADhere-J study., Methods: Patients aged ≥12 years and weighing ≥40 kg with moderate-to-severe AD, and receiving either subcutaneous lebrikizumab 250 mg every 2 weeks (Q2W)/every 4 weeks (Q4W) or placebo during the 16-week induction period, were evaluated during the long-term maintenance period from W16 to W68. Responders achieved co-primary endpoints at W16: Investigator's Global Assessment score of 0 or 1 (IGA [0,1]) with ≥2-point improvement from baseline, and/or ≥75% improvement from baseline in Eczema Area and Severity Index (EASI 75). In this analysis, W16 responders received lebrikizumab 250 mg Q2W or Q4W combined with TCS during the maintenance period (maintenance primary population; MPP); W16 per-protocol nonresponders received lebrikizumab Q2W with TCS (maintenance escape population; MEP). Major endpoints included IGA (0,1) with ≥2-point improvement from baseline and EASI 75 through W68. Other outcomes included QOL, itch, and serum thymus and activation-regulated chemokine., Results: At W68, 66-81% of 103 patients in the MPP and 32-38% of 168 patients in the MEP achieved IGA (0,1) with ≥2-point improvement from baseline. EASI 75 was maintained by 83-89% of patients in the MPP, while 71-80% of patients in the MEP achieved this outcome by W68. Across treatment arms, patients in the MPP tended to maintain improvements recorded at W16, while patients in the MEP steadily improved across the maintenance period. No new safety signals were reported, and most treatment-emergent adverse events were mild or moderate in severity in both populations. Safety outcomes were consistent with previous reports for lebrikizumab treatment in global studies., Conclusions: These results support the use of lebrikizumab in combination with TCS for moderate-to-severe AD in the Japanese population over the long term., Clinical Trial Registration: ClinicalTrials.gov (NCT04760314)., (© The Author(s) 2024.

Pencil-core granulomas grow rapidly after a long incubation period, typically taking years to decades after penetration by the pencil core. However, colored pencil-core granulomas, which have different core components, have been reported to form just a few days after the core has pierced the skin. It is understood that this difference in incubation period is due to differences in reactivity to different types of foreign bodies. However, we report a rare case of colored pencil-core granuloma that took a three-month incubation period despite being caused by a green pencil-core., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Urticaria is characterized by the development of wheals which usually disappear within a day, and are not present beyond a few days. A 58-year-old man began to develop edematous, partially ring-shaped erythematous lesions accompanied by severe body itching without any particular cause, approximately 2 months before his first visit to our hospital. Each rash emerged as being about 5 mm in diameter, gradually enlarging over several days, and disappeared in up to 10 days. Despite oral treatment with several antihistamines and 10 mg of prednisolone, there was no improvement. Most eruptions disappeared without a trace, but the erythema that appeared on the palms left desquamation. The patient had a history of shellfish allergy, but otherwise no atopic diseases. Drug eruption was ruled out due to a lack of regular taking other medications. Histopathological findings of the skin lesions showed moderate lymphocytic and few eosinophilic infiltrates with edema, but no evidence of vasculitis. Despite the concomitant use of two second-generation antihistamines and montelukast, the rash did not improve. The symptoms began to improve following oral intake of 1.5 mg of betamethasone, which was tapered off with the addition of 150 mg of cyclosporin. The use of all medications was stopped at 4 months from the first visit without recurrence. Wheals of chronic spontaneous urticaria may last for longer than a week without apparent histopathological findings of vasculitis., (© 2024 The Author(s).

Lebrikizumab has previously demonstrated efficacy in Phase 3 trials: ADvocate1 and ADvocate2 (as monotherapy), ADhere, and ADhere-J (in combination with topical corticosteroids). Here, the impact of lebrikizumab combined with low- to mid-potency topical corticosteroids on patient-reported outcomes at 16 weeks in Japanese patients with moderate-to-severe atopic dermatitis is evaluated. Eligible patients (n = 286) were randomized 2:2:3 to receive placebo+ topical corticosteroids, 250 mg lebrikizumab every 4 weeks (LEBQ4W+topical corticosteroids, 500 mg loading dose at baseline), or 250 mg lebrikizumab every 2 weeks (LEBQ2W+ topical corticosteroids, 500 mg loading dose at baseline and Week 2) by subcutaneous injection. All PRO endpoints for the study were met; patients in the lebrikizumab in combination with topical corticosteroids groups demonstrated statistically significant and clinically meaningful improvements compared with placebo in combination with topical corticosteroids in Skin Pain NRS, DLQI, POEM, WPAI-AD, and SCORAD scales. Lebrikizumab combined with topical corticosteroids compared with placebo+topical corticosteroids improved patient-reported outcomes in Japanese patients with moderate-to-severe atopic dermatitis.
