Christina M Huang, Mark G Kirchhof
BACKGROUND: Hidradenitis suppurativa (HS) is a disease characterized by the development of painful, deep-seeded nodules and abscesses. Treatment guidelines include a combination of lifestyle, surgical, and medical interventions. Isotretinoin has not been included in the treatment guidelines due to the limited number of studies and conflicting reports of efficacy. OBJECTIVES: The purpose of this study is to evaluate the clinical response to isotretinoin in HS patients and to determine whether there is a particular patient population that may benefit more from this treatment...

Rosacea is a chronic facial dermatosis considered to affect primarily white patients with light phototype skin, and is poorly documented in black patients. The aim of this study was to document the clinical features of rosacea in patients with phototypes V and VI. An 8-year retrospective chart review of patients with a clinical and histological diagnosis of rosacea or acne rosacea was undertaken. Of 6700 patients, 15 (0.2%) had rosacea. All were of African descent with skin phototype V or VI. Mean age was 47 years, and female : male ratio was 14 : 1...

Propionibacterium acnes (P. acnes) is a Gram-positive anaerobic rod and a common skin commensal that colonizes sebaceous glands. It has infrequently been associated with invasive opportunistic infections and can cause implant-associated infections through a biofilm mode of growth. Medical thoracoscopy is a common procedure for diagnosis and treatment of exudative pleural effusions; empyema is a recognized complication. We present a rare case of P. acnes pleural empyema 3 weeks following medical thoracoscopy and subsequent intercostal drain insertion for 3 days in a 75-year-old man...

Oral retinoids and tetracyclines have a major role in acne treatment. Here, we report for the first time the effect of isotretinoin and lymecycline therapy on the skin microbiota in cheek, back and armpit swab samples of acne vulgaris patients using 16S ribosomal RNA (16S rRNA) gene amplicon sequencing. Propionibacterium acnes was the most common in sebaceous areas of healthy and untreated acne skin and more abundant in back than cheek samples. Five taxa, including a Streptococcus taxon, differed significantly between the cheek samples of healthy controls and acne patients, and acne severity was positively correlated with the abundance of Propionibacterium...

Moyamoya disease is a unique occlusive disease of the internal carotid artery(ICA)with moyamoya vessels that can lead to transient ischemic attacks and hemorrhagic stroke. When other inherited or acquired disorders and conditions occur in conjunction with moyamoya disease, the syndrome is known as quasi-moyamoya disease. We report the case of a 34-year-old woman with a past history of SAPHO(Synovitis-Acne-Pustulosis-Hyperostosis-Osteomyelitis)syndrome, who presented with arm weakness and headache. Magnetic resonance angiography revealed severe terminal stenosis of the left ICA with moyamoya vessels, and she was diagnosed as moyamoya disease associated with SAPHO syndrome...

The search for new, effective and safe antimicrobial compounds from plant sources has continued to play an important role in the maintenance of human health since ancient times. Such compounds can be used to help to eradicate microorganisms from the root canal system, preventing/healing periapical diseases. Mikania glomerata (Spreng.), commonly known as "guaco," is a native climbing plant from Brazil that displays a wide range of pharmacological properties. Many of its activities have been attributed to its phytochemical composition, which is mainly composed of diterpenes, such as ent-kaurenoic acid (KA)...

Despite the impressive increase of knowledge on acne etiology accumulated during the last 20 years, few efforts have been overtaken to introduce new therapeutic regiments targeting the ideal treatment of acne. The increasing emergence of microbial resistance associated with antibiotics, teratogenicity, particularly associated with systemic isotretinoin, and the need for an adverse drug profile, which can be tolerated by the patient, make the need of new pathogenesis relevant anti-acne agents an emerging issue...

Chitosan (CS) is a material derived from chitin, the most abundant biopolymer on the planet. It has shown potential among a wide variety of biomedical applications especially within the context of self-assembling nanocarriers usable in biomedical applications such as drug delivery, macroscopic injectables, tissue-engineering scaffolds, and nano-imaging agents. To date, many reviews have been focused on the biomedical properties and applications of CS-based nanocarriers, but a review is lacking on the role and prospects of different factors such as formulation parameters and preparation conditions on the properties of amphiphilic chitosan nanocarriers (ACNs) that have shown critical value in advancing drug delivery...

BACKGROUND: The incidence of preadolescent acne among women is increasing. Acne deteriorates the quality of life; conventional treatment options are limited and have not been effective against acne, particularly acne associated with menstruation. Despite evidence that acne associated with menstruation abnormalities naturally improves when menstruation recovers to normal, there have only been few studies on the effects of dysmenorrhea treatment on acne. Therefore- we designed this study to assess the effects of gyejibokryung-hwan (GBH) and dangguijagyag-san (DJS), which are widely used in dysmenorrhea treatment, on acne associated with menstruation cycle...

The prevalence of antimicrobial-resistant Propionibacterium acnes strains isolated from acne patients has been increasing in Japan. Here, to estimate the current resistance rate, we tested antimicrobial susceptibility among P. acnes from acne patients having visited a specialized dermatology clinic between 2013 and 2015. Rates of resistance to macrolides and clindamycin were 44.3 (31/70) and 38.6% (27/70), respectively. erm(X), which confers high-level clindamycin resistance (minimum inhibitory concentration ≥256 μg/mL), was detected in six isolates, whereas no resistance determinants were identified in eight strains showing high-level resistance to clindamycin...

Contagious porcine pleuropneumonia (CPP), caused by Actinobacillus pleuropneumoniae (APP), is a highly transmissible and fatal respiratory illness that causes tremendous economic losses for the pig breeding industry worldwide. Propionibacterium acnes (PA) has a strong cross-reaction with anti-APP1 and anti-APP5 serum and can efficiently prevent APP infection, which was fortuitously found in researching the differential gene between the different APP serotypes. There seems to be some natural cross-protection between PA and APP...
