Acne is the most common skin disorder and can directly affect the patients' self-esteem. Systemic treatment has been indicated for nodular, cystic or persistent acne rather than another type of treatment, such as a topic one. Isotretinoin is an analogue of vitamin A and by suppressing the sebaceous glands the disease can be controlled. This study was designed to mimic the treatment performed in young patients using the dosage of 1mg/kg, and a higher one of 10mg/kg, for 60days in young male Wistar rats. 24 Wistar rats were divided into four groups: control(water), D0(soybean oil, control group), D1(1mg/kg of Isotretinoin solution), D10(10mg/kg of Isotretinoin solution)...

PURPOSE: To report a case unilateral excessive subretinal fluid during the use of isotretinoin. METHOD: A case report. A patient who used isotretinoin orally for nodular-cystic acne vulgaris developed concurrent unilaterally excessive subretinal fluid and serous retinal detachment. RESULTS: Fluorescein angiography did not demonstrate the leakage points throughout the subretinal fluid. Spectral-domain optical coherence tomography showed the excessive subretinal fluid and serous retinal detachment at macula...

Isotretinoin a synthetic analogue of vitamin A is primarily used for cystic acne not responding to conventional treatment. Several ocular side effects including blurring of vision, decreased dark adaptation, corneal opacities and meibomian gland atrophy have been reported with prolonged use of isotretinoin. There have been reports of muscular damage caused by isotretinoin. Extra ocular myopathy as an adverse effect of long term used of isotretinoin has never been mentioned in literature. We report a case of a young male who presented to us with complaints of diplopia after using isotretinoin for a prolonged period...

Acne is one of the most prevalent skin conditions seen by dermatologists. The cosmetic sequelae of severe acne, including scarring and pigmentation, have a profound psychological impact on those in icted. Topical (eg, retinoids, antibiotics, dapsone, hydroxyacids) and oral treatments (eg, antibiotics and/or spironolactone) are often bene cial to control acne or in the instance of oral isotretinoin use, rid the acne permanently; however, these treatments have very little affect on the ultimate cosmetic outcome of the acne scarring and skin texture that results...

A previously healthy 3-year-old boy presented to the emergency department with abdominal pain, fever, and emesis. Laboratory and radiologic evaluation for causes of acute abdomen were negative; however, review of the abdominal x-ray demonstrated cardiomegaly with the subsequent diagnosis of pericardial cyst by echocardiogram and computed tomography. The patient underwent surgical decompression and attempted removal of the cystic structure revealing that the cyst originated from the epicardium. His abdominal pain and fever resolved postoperatively and he completed a 3-week course of ceftriaxone for treatment of Propionibacterium acnes infected congenital epicardial cyst...

Acne is a chronic inflammatory disease whose psychosocial effects can greatly impair quality of life. Various scales are used to classify the severity of acne, and several treatment algorithms are currently applied: no consensus on a common scale or treatment guidelines has been reached. A group of Spanish experts therefore met to identify a scale the majority could accept as the most appropriate for classifying severity and treating accordingly. The group chose the following classifications: comedonal acne, mild or moderate papulopustular acne, severe papulopustular acne, moderate nodular acne, and nodular-cystic acne (or acne tending to leave scars)...

Sarah Qureshi, Jennifer Y Lin
Aminolevulinic acid (ALA) photodynamic therapy (PDT) is an emerging modality in the treatment of acne. While ablative fractional lasers have been used to enhance drug delivery into the epidermis, recent evidence suggests that non-ablative fractional photothermolysis may also improve uptake of ALA. We explored the use of non-ablative 1550 nm laser as a safe alternative in the delivery of ALA prior to red-light PDT for refractory inflammatory and cystic acne. Subjects referred for treatment of acne refractory to several topical and oral regimens, including isotretinoin, were pre-treated with non-ablative fractional photothermolysis (NAFP)...

INTRODUCTION: Acne vulgaris commonly affects adolescents. But recent reports suggest a rising prevalence of post-adolescence acne. While there are few reports on post-adolescence acne, there are even fewer reports comparing adolescence acne and post-adolescence. METHODS: Epidemiological data of adolescence (<25 years) and post-adolescence (≥25 years) acne patients diagnosed between 2004 and 2013 in a tertiary dermatology referral centre was analysed. From the pool of patients seen in 2010, 80 adolescence and 84 post-adolescence acne patients' epidemiological characteristics and treatment responses were analysed...

BACKGROUND: Cystic fibrosis (CF) is the most common severe autosomal recessive disorder in Caucasians. Viscous secretionstypically obstruct the lungs, pancreas, and gastrointestinal tract. As disease management improves, patients will increasingly seek care for conditions such as acne. Isotretinoin therapy for acne in patients with CF is controversial owing to concerns that the medication may exacerbate CF-related hepatic, pulmonary, and ocular complications. PURPOSE: We describe two patients with CF treated with isotretinoin from our clinic and also provide a literature review of 11 similar cases...

BACKGROUND: Isotretinoin, a teratogen, is widely used to treat cystic acne. Although the risks of pregnancy during isotretinoin therapy are well recognized, there are doubts about the level of adherence with the pregnancy prevention program in Canada. Our objective was to evaluate the effectiveness of the Canadian pregnancy prevention program in 4 provinces: British Columbia, Saskatchewan, Manitoba and Ontario. METHODS: Using administrative data, we identified 4 historical cohorts of female users of isotretinoin (aged 12-48 yr) for the period 1996 to 2011...

OBJECTIVE: The CYP19A1 gene product aromatase is responsible for estrogen synthesis and androgen/estrogen equilibrium in many tissues, particularly in the placenta and gonads. Aromatase deficiency can cause various clinical phenotypes resulting from excessive androgen accumulation and insufficient estrogen synthesis during the pre- and postnatal periods. In this study, our aim was to determine the clinical characteristics and CYP19A1 mutations in three patients from a large Turkish pedigree...

Acne vulgaris is a common disease of the pilosebaceous unit and affects adolescents and adults. Because high-quality guidelines regarding treatment of acne in pregnancy are scarce, management of this condition can be challenging. We describe the safety profile of common therapies and outline approaches based on available evidence. Topical azelaic acid or benzoyl peroxide can be recommended as baseline therapy. A combination of topical erythromycin or clindamycin with benzoyl peroxide is recommended for inflammatory acne...

BACKGROUND: Dioxins are persistent organic pollutants present in the environment. They exert their biological effects by binding to an intracellular receptor, the aryl hydrocarbon receptor (AhR). Activation of AhR leads to the induction of cytochrome p450 1A1 (CYP1A1). Expression of CYP1A1 in human skin is a key marker for AhR activation, and it may induce comedogenesis resulting in acne-like lesions known as chloracne/metabolising acquired dioxin-induced skin hamartomas (MADISH). The contribution of this pathway in patients seen in a busy acne clinic is unknown...

OBJECTIVE: The oral retinoid agent isotretinoin (13-cis-retinoic acid) is approved for the treatment of severe recalcitrant cystic acne. For registrational renewal of Oratane® in Mexico (isotretinoin; Laboratorios Dermatologicos Darier S.A. de C.V., Mexico), it was necessary to establish bioequivalence to the reference product Roaccutan® (Isotretinoin; Roche, Mannheim, Germany). Three prior studies failed to establish the bioequivalence of Oratane to Mexican-sourced Roaccutan. However, 13 studies demonstrated the bioequivalence of Oratane to Roaccutane® from multiple sources...

We present the case of a 35-year-old man with thoracic back pain and stiffness, whose only medical history was cystic acne treated with repeated courses of retinoids. His thoracic spine was severely limited in range of movement and was found, on X-ray, to have unilateral hyperostosis typical of diffuse idiopathic skeletal hyperostosis (DISH)--an often asymptomatic condition rarely found in those under 50. Back stiffness in young patients with prolonged retinoid exposure should be investigated.

Making accurate diagnoses when certain lesions are in a relatively young stage can prove challenging, as their "textbook descriptions" are often not fully apparent, and may in fact be markedly different. The authors present three interesting cases of early lesions that were clinically difficult to differentiate from one another: a cystic variation of a keratoacanthoma squamous cell carcinoma, a basal cell carcinoma, and an excoriated facial acne vulgaris. The subtle clinical nuances found in each of these cases demonstrated the importance of a careful clinical evaluation; however, this was not sufficient for adequate assessment of whether or not to biopsy...
