Changes in the Use of Hydrochlorothiazide and Other Antihypertensive Drugs in Switzerland in Association With the Swissmedic Safety Alert Regarding Non-melanoma Skin Cancer: An Interrupted Time-Series Analysis Using Swiss Claims Data.

Purpose: Long-term use of hydrochlorothiazide increases the risk of non-melanoma skin cancer. We aimed to evaluate potential changes in the use of hydrochlorothiazide in Switzerland after a direct healthcare professional communication (DHPC) in November 2018 by Swissmedic.

Methods: We performed interrupted time-series analyses using a large Swiss healthcare claims database (2015-2021).

Importance of histopathological analysis and molecular genetics in a rare neonatal case of rhabdomyosarcoma.

We present a case of a neonate who presented with multiple cutaneous and subcutaneous nodules, which was found to be metastatic embryonal rhabdomyosarcoma. Rhabdomyosarcoma is a soft tissue malignancy that usually occurs in children aged one to five but is rare in neonates. The histopathological analysis and molecular genetics are important in the classification of subtype and in guiding treatment options and informing prognosis.

Improving the patient-centred care of children with life-altering skin conditions using feedback from electronic patient-reported outcome measures: protocol for a hybrid effectiveness-implementation study (PEDS-ePROM).

Introduction: Using patient-reported outcome measures (PROMs) with children have been described as 'giving a voice to the child'. Few studies have examined the routine use of these measures as potentially therapeutic interventions. This study aims to investigate: (1) the of feedback using graphical displays of information from electronic PROMs (ePROMs) that target health-related quality of life, to improve health outcomes, referrals and treatment satisfaction and (2) the of ePROMs and graphical displays by assessing acceptability, sustainability, cost, fidelity and context of the intervention and study processes.

Consensus statement for the treatment of infantile haemangiomas with propranolol.

Although most infantile haemangiomas do not require treatment due to a natural history of spontaneous involution, some require early intervention. The Australasian Vascular Anomalies Network and the Australasian Paediatric Dermatology Network have developed a consensus statement for the treatment of infantile haemangiomas with oral propranolol. Infants with haemangiomas that are life threatening, at risk of ulceration, or at risk of causing a significant functional impairment, psychological impact or physical deformity should be treated early with oral propranolol.

Red-white and blue baby: a case of phacomatosis pigmentovascularis type V.

Phacomatosis pigmentovascularis is a rare genodermatosis characterized by the combination of an extensive pigmentary nevus with a widespread vascular nevus. The coexistence of aberrant dermal melanocytosis and cutis marmorata telangiectatica congenita has been termed phacomatosis pigmentovascularis type V or phacomatosis cesiomarmorata. Phacomatosis pigmentovascularis type V was first described in a 3-month-old boy in 2000.

Dermatological reactions to ophthalmic preparations: more than meets the eye.

Ophthalmic preparations are commonly used medications that have been implicated in causing a variety of dermatological reactions. These reactions include toxic epidermal necrolysis, anaphylaxis, fixed drug eruption, lichenoid drug reaction and local and systemic contact dermatitis. This article reviews the dermatological and systemic reactions associated with ophthalmic preparation use and highlights the need for a thorough medication history to be done for all patients presenting with a suspected drug reaction.

Toxic epidermal necrolysis caused by over the counter eyedrops.

We present a case of a 15-year-old boy who developed toxic epidermal necrolysis (TEN) from sulfacetamide eyedrops. He presented with conjunctival injection and an erythematous rash that rapidly progressed to epidermal necrosis of over 30% of his body. A skin biopsy revealed an acute lichenoid reaction pattern consistent with TEN.

Hydroxyurea induced dermatomyositis-like eruption.

Medication-induced dermatomyositis (DM) is rare, but a recent review highlighted hydroxyurea (HU) as the most common inciting agent. To aid diagnosis, HU-induced DM-like eruption (HU DM-LE) forms a distinct dermopathy where the typical cutaneous features of DM are without systemic involvement and co-exist with other HU-induced cutaneous findings such as severe xerosis, atrophy, stomatitis, cutaneous and mucosal ulceration and melanonychia. On cessation of HU the DM-LE clears avoiding unnecessary immunosuppression and demonstrating the importance of consideration of medication aetiology in DM presentations.
