INTRODUCTION The high rate of relapse of acne lesions following oral isotretinoin treatment is a common problem which remains unsolved. To avoid or minimize relapses, topical retinoids have been used for many years as maintenance treatment. However, adverse effects frequently occur. AIMS To determine the efficacy and safety of a new retinoid combination (Retinsphere technology) in maintaining...

BACKGROUND/AIM Systemic isotretinoin treatment is an effective treatment modality for nodulocystic acne, the clinical use of which has been associated with reports of adverse events. We conducted a prospective study with the aim of determining the possible gastrointestinal and laboratory findings of nodulocystic acne patients during systemic isotretinoin treatment. MATERIALS AND METHODS Seven...

To explore the possible mechanism of the third-generation retinoic acid drugs (isotretinoin, acitretin, adapalene) in inducing skin and mucosa dryness and rhagades; specifically, mechanism by which these drugs influence keratinocyte cell culture models in vitro (HaCaT) and aquaporin channel (AQP3) protein expression was investigated. Isotretinoin, acitretin, and adapalene were applied to human ...

Purpose. We report the effect of isotretinoin on corneal topography, corneal thickness, and biomechanical parameters in patients with acne vulgaris. Method. Fifty-four eyes of 54 patients who received oral isotretinoin for treatment of acne vulgaris were evaluated. All patients underwent a corneal topographical evaluation with a Scheimpflug camera combined with Placido-disk (Sirius), ultrasonic...

The aim of this study was to compare the clinical and microbiological effect on Propionibacterium acnes of oral tetracycline plus topical adapalene vs. oral isotretinoin in moderate to severe acne vulgaris. Male and female acne patients with moderate or severe inflammatory disease were enrolled and assigned randomly to 6 months of treatment with oral tetracycline hydrochloride plus topical adap...

Objective. This prospective open trial aimed to evaluate the efficacy and safety of isotretinoin (13-cis-retinoic acid) in patients with Cushing’s disease (CD). Methods. Sixteen patients with CD and persistent or recurrent hypercortisolism after transsphenoidal surgery were given isotretinoin orally for 6–12 months. The drug was started on 20mg daily and the dosage was increased up to 80mg dail...

In recent years, several cases pointing at sacroiliitis due to isotretinoin treatment have been reported, but a causal association remains unproven. The aim of this study was to assess the characteristics of patients in whom bilateral sacroiliitis was detected while using isotretinoin treatment for acne and to review previous sacroiliitis cases treated with isotretinoin. In total, 11 patients w...

IMPORTANCE Isotretinoin is the most effective treatment for acne. The ideal dosing regimen is unknown. OBJECTIVE To determine the rates of relapse of acne vulgaris and retrial of isotretinoin after high cumulative-dose treatment and the changes to the adverse effect profile. DESIGN, SETTING, AND PARTICIPANTS A prospective, observational, intervention study was conducted from August 1, 2008,...

In a busy practice, physicians may be discouraged by the prospect of having to log onto yet another website or navigate more protocols to carry out patient care.
