Adult cystic acne

BACKGROUND: Relapse rates in patients with acne after treatment with oral isotretinoin vary between 10% and 60% depending on the dosage regimen used, the length of follow-up, and the characteristics of the study population. The aim of this study was to determine the acne relapse rate within 2 years of completion of isotretinoin therapy and to identify the prognostic factors associated with relapse. MATERIAL AND METHODS: We studied a series of patients with cystic acne who had received a cumulative therapeutic dose of at least 120 mg/kg of oral isotretinoin...

BACKGROUND: Isotretinoin (13-cis retinoic acid) is used for treatment of nodular cystic acne unresponsive to conventional therapy. It is an expensive, potent teratogenic drug with serious adverse drug reaction (ADRs). Recently, use of this drug has increased in Iran. To date, there are no published data about the use of isotretinoin in Iran; therefore, this study aims to assess its use in this country. METHODS: This was a prospective, drug utilization evaluation (DUE) study conducted in an institutional community pharmacy affiliated with Tehran University of Medical Sciences (TUMS)...

OBJECTIVE: To describe the genotypes, phenotypes, immunophenotypes, and treatments of PAPA syndrome (pyogenic sterile arthritis, pyoderma gangrenosum, and acne), a rare autoinflammatory disease, in 5 patients. METHODS: Clinical information was gathered from medical records and through interviews with 5 patients from 4 kindreds. PSTPIP1 (CD2BP1) exon 10 and exon 11 sequencing was performed in each patient. Neutrophil granule content and cytokine levels were determined in plasma and stimulated peripheral blood mononuclear cells (PBMCs) from patients and controls...

OBJECTIVE: To verify the clinical efficacy of warming moxibustion on cystic acne. METHODS: Ninety-four cases were randomized into an observation group, control group 1 and control group 2. The basic treatment of body acupuncture combined with fire needling was applied in all of three groups. In observation group, cone moxibustion was added on Guanyuan (CV 4), Qihai (CV 6) and Pishu (BL 20). In control group 1, Isotritinoin soft capsule was taken orally, and in control group 2, no any other therapy was administered...

BACKGROUND: Inflammatory cystic acne has been treated by a variety of modalities including antibiotics, topical agents, isotretinoin and chemical peels with variable degrees of success. Erbium:YAG lasers have been used for the treatment of acne scarring and photoaged skin but have not been thought of as treatment for actively inflamed lesions. OBJECTIVE: We sought to ascertain the effectiveness of using low fluence erbium:YAG settings without topical anesthesia for the treatment of two patients with inflamed cystic acne...

BACKGROUND: Keratitis-ichthyosis-deafness (KID) syndrome is a rare ectodermal dysplasia characterized by generalized erythrokeratotic plaques, sensorineural hearing loss, and vascularizing keratitis. Cutaneous changes and hearing loss typically present in early childhood, whereas ocular symptoms present later. Mutations in the connexin (Cx) 26 gene, GJB2, are now established to underlie many of the affected cases, with the majority of patients harboring the p.D50N mutation. METHODS: A rare patient demonstrating features of incomplete KID syndrome associated with an uncommon Cx26 gene mutation is described...

BACKGROUND: Isotretinoin (Accutane(R)) has been available for the treatment of severe cystic acne for about twenty-five years. There have been several reports of adverse psychiatric reactions to isotretinoin, including depressive symptoms and suicide. However, there have been only three case reports of patients with bipolar disorder (BD) who experienced an untoward psychiatric side effect while receiving isotretinoin treatment. In this study, the psychiatric side effects from isotretinoin were assessed in a larger group of BD patients than has previously been reported...

BACKGROUND: Acne vulgaris is a multifactorial inflammatory disease of the sebaceous follicles of the face and torso that frequently occurs in adolescence. Initially, acne starts as a non-inflammatory comedo. Subsequently, inflammatory reactions evolve to pustules, granulomas and cystic lesions. Many pathogenic mechanisms have been proposed including sebum excretion, obstruction of hair follicles, impaired keratinization of hair epithelium, bacterial overgrowth and immunological mechanisms; the role of Propionibacterium acnes (P...

PURPOSE: Isotretinoin (Iso) has marked side effects. Homocysteine (Hcy) metabolizes in the liver, requiring folate and vitamin B12. Elevated blood levels of Hcy have been linked to an increased risk of premature coronary artery disease (CAD). In this study, we evaluated Hcy levels, vitamin B12, and folate in patients on Iso treatment for cystic acne (CA). METHODS: Seventy-four patients with CA were included to the study group. Blood levels of Hcy, vitamin B12, and folate were assessed before and after 45 days of Iso therapy...

BACKGROUND: Acne, a chronic inflammatory dermatosis of the pilosebaceous follicle, is very widespread worldwide, affecting 75-80% of adolescents, with an impact on their quality of life. The etiologic factors are not always the same, and the treatments proposed are not always well tolerated in black individuals. AIMS: To determine how acne affects the black population in Dakar, Senegal, and to assess the results of and tolerance to treatment. METHODS: This was a prospective study conducted on a sample of patients who attended consultations for acne in our dermatology department between December 2002 and March 2003, and who agreed to take part in the study (informed consent was obtained)...

Acne vulgaris is the most common skin disease treated by physicians. Current topical and oral treatments may have short- and long-term negative consequences. Since radiofrequency (RF) energy has been shown to reduce sebum production and 410-nm blue light has been shown to kill Propionibacterium acnes (P. acnes) cells, these modalities in combination should be a highly effective treatment of acne vulgaris with little or no downtime or risk. This case report describes the efficacy and safety of RF energy (Accent, Alma Lasers Inc, Buffalo Grove, IL) and blue light (BLU-U, Dusa Pharmaceuticals, Inc, Wilmington, MA) used in combination to treat grade 4 cystic acne and acne scars in an Asian woman of skin type IV...

Acne conglobata is an uncommon disorder characterized by the presence of nodulocystic lesions. Conservative therapy with oral and topical antibiotics is of limited efficacy in many cases, and surgical excision is often needed for removal of the cystic lesions. Treatment is particularly difficult in cases with lesions located in aesthetically sensitive areas, such as the face. We successfully treated a case of acne conglobata by CO(2) laser ablation to remove the top of the sinuses and their tracts. In addition, topical tretinoin therapy was also initiated simultaneously to prevent the appearance of new acne lesions...

Aromatase deficiency is rare in humans. Affected individuals cannot synthesize endogenous estrogens. Aromatase is the enzyme that catalyzes conversion of androgens into estrogens, and if aromatase is nonfunctional because of an inactivating mutation, estrogen synthesis cannot occur. If the fetus lacks aromatase activity, dehydroepiandrosterone sulfate produced by the fetal adrenal glands cannot be converted to estrogen by the placenta, so is converted to testosterone peripherally and results in virilization of both fetus and mother...

INTRODUCTION: 47,XYY karyotype occurs in 1 out of 1,000 male births. Physical phenotype is normal, with tall stature by adolescence. Prenatal diagnosis of the 47,XYY syndrome is usually fortuitous. Some cases are being diagnosed when prenatal karyotyping is done for the detection of Down syndrome and other major aneuploidies. Some cases are diagnosed when prenatal ultrasonographic findings of fetal abnormalities are found. Herein, we report a case of 47,XYY after prenatal finding of fetal cystic hygroma with spontaneous resolution...

BACKGROUND: Acne vulgaris affects a large number of young adults and often presents with facial and truncal involvement. Systemic antibiotics are used for the treatment of papulopustular and cystic lesions. OBJECTIVE: We sought to determine the efficacy and safety of azithromycin versus tetracycline in the treatment of acne vulgaris. METHODS: A randomized, investigator-blind, clinical trial was carried out for 3 months at the outpatient clinic of Emam Khomeini University Hospital, Ahwaz, Iran...

CONTEXT: Nonclassical congenital adrenal hyperplasia (CAH) owing to steroid 21-hydroxylase deficiency (NC21OHD) is the most frequent of all autosomal recessive genetic diseases, occurring in one in 100 persons in the heterogeneous New York City population. NC21OHD occurs with increased frequency in certain ethnic groups, such as Ashkenazi Jews, in whom one in 27 express the disease. NC21OHD is underdiagnosed in both male and female patients with hyperandrogenic symptoms because hormonal abnormalities in NC21OHD are only mild to moderate, not severe as in the classical form of CAH...

Isotretinoin (13-cis-retinoic acid) is a retinoid that is used to treat cystic acne, comedonal acne, and other diseases. For the treatment of acne, isotretinoin is dosed at 0.5 to 2 mg/kg daily for 5 months with a target total dose of approximately 120 mg/kg. Its most common side effects are mucocutaneous and ocular in nature (ie, cheilitis, ocular sicca, and decreased dark adaptation). It can also cause xerosis. Patients should be made aware of these side effects before taking isotretinoin and also that utilization of moisturizers and eye drops can help to mitigate such side effects...

We report four patients diagnosed with black discoloration of the thyroid gland at surgery and a fifth patient in which the "black thyroid" was an incidental finding at autopsy. The four patients diagnosed at surgery had prior fine-needle aspirations (FNA), which did not reveal any characteristic pigmentation. One patient presented with cervical lymph node metastases from a papillary microcarcinoma of thyroid. The second patient was diagnosed as a cellular adenomatoid nodule, and suppressive therapy was recommended...

BACKGROUND: Acne patients who fail to respond to conventional treatments have been treated with isotretinoin, an effective treatment coming under strict regulation due to the risk of significant side effects. Photodynamic therapy (PDT) may be a viable alternative treatment for recalcitrant acne of various types and levels of severity. OBJECTIVE: To determine the safety and efficacy of combination PDT with topical 5-aminolevulinic acid (ALA) and activation by long-pulsed, pulsed dye laser (LP PDL, 595 nm) energy with topical therapy in patients with mild to severe acne...

Photodynamic therapy with short-contact 5-aminolevulinic acid (Levulan Kerastick, Dusa Pharmaceuticals, Inc.) and activation by intense pulsed light in an initial treatment and blue light in 3 subsequent treatments has resulted in significant improvement in severity of acne, reduction in the number of lesions, improvement in skin texture, and smoothing of scar edges in an Asian patient with severe (class 4) facial cystic acne and scarring.
