A 53-year-old man with a history of Crohn's disease on infliximab, presented with several weeks of cough and dyspnoea. He had a right-sided pleural effusion, found to be exudative with lymphocytic predominance. He underwent right-sided video-assisted thoracic surgery (VATS) with biopsies and pleurodesis. Histopathology showed pleural-based non-caseating granulomas with unremarkable lung parenchyma. Cultures were only positive for Propionibacterium acnes 8 months later, he was found to have a left-sided exudative, lymphocytic predominant pleural effusion...

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...

We have investigated the accumulation of porphyrins in Propionibacterium acnes (P.acnes) by 5-aminolevulinic acid hydrochloride (ALA) and its esters, ALA methyl ester hydrochloride (mALA), ALA octyl ester hydrochloride (oALA), and ALA benzyl ester hydrochloride (bALA). From the fluorescence spectra of porphyrins accumulated in P.acnes, the order of porphyrin accumulation is as follows: ALA≫mALA≈bALA>oALA (≈0). Moreover, the PDT efficacy is reduced in the order of ALA>mALA≈bALA>oALA (≈without additives)...

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...

Acute scrotal abscess is an extremely rare condition in neonates and may mimic testicular torsion. Most of these abscesses have reportedly been due to Staphylococcus and Salmonella spp. infections. We herein report a unilateral acute scrotal abscess in a preterm infant born at 26 weeks in whom Propionibacterium acnes was isolated from the collected scrotal fluid culture. To our knowledge, this is the first case report implicating P. acnes as a causative agent of neonatal scrotal abscess. Based on such findings, P...

BACKGROUND: Glycemic index (GI) and glycemic load (GL) may be implicated in acne pathogenesis. OBJECTIVE: This cross-sectional study examined differences between GI/GL and biological factors associated with acne among adults with and without moderate/severe acne. Secondary objectives included examining differences between food-aggravated acne beliefs and acne-specific quality of life among adults with and without moderate/severe acne. DESIGN: As part of a cross-sectional study, participants completed a 5-day food record; blood draw to measure biological factors associated with acne (ie, glucose, insulin, insulin-like growth factor-1, insulin-like growth factor binding protein-3, and sex hormone-binding globulin concentrations); body composition assessment; and questionnaire to evaluate food-aggravated acne beliefs and acne-specific quality of life...

A preliminary study is reported for a polycation antimicrobial peptide (AMP) mimic against Propionibacterium acnes, which is associated with acne vulgaris, a common skin condition. Antibiotics are commonly used against P. acnes but buildup of resistance is well-known. Worse, antibiotic regimens build up resistance for more sensitive bacteria such as Staphylococcus epidermidis. The polycation AMP mimic C12-50, 1, is chosen for the present study as it has been previously shown to have high antimicrobial effectiveness...

In vitro occurrence of levofloxacin (LVX) resistance in C. acnes and characterization of its molecular background were investigated. The mutation frequency was determined by inoculation of 10(8) cfu of C. acnes ATCC 11827 (LVX MIC = 0.25 mg/L) on LVX-containing agar plates. The progressive emergence of resistance was studied by a second exposure to increasing LVX concentrations. For mutants, the QRDR regions including the gyrA and parC genes were sequenced and compared to both C. acnes ATCC 11827 and C...

The object of this study was to discover an alternative therapeutic agent with fewer side effects against acne vulgaris, one of the most common skin diseases. Acne vulgaris is often associated with acne-related bacteria such as Propionibacteriumacnes, Staphylococcusepidermidis, Staphylococcusaureus, and Pseudomonasaeruginosa. Some of these bacteria exhibit a resistance against commercial antibiotics that have been used in the treatment of acne vulgaris (tetracycline, erythromycin, and lincomycin). In the current study, we tested in vitro antibacterial effect of chitosan-phytochemical conjugates on acne-related bacteria...

Acne vulgaris is a disease of pilosebaceous units with multifactorial pathogenesis, including hyperkeratinization, increased sebum secretion, and inflammation. Recently, it was suggested that acne subjects may have also impaired skin barrier. We hypothesized that excess unsaturated free fatty acids (UFFA) present in the sebum may cause barrier impairment associated with increased follicular stratum corneum (SC) thickening and inflammation seen in acne. Therefore, epidermal and sebaceous lipid profiles from acne and healthy subjects were analyzed and an in vitro epidermal tissue model was developed to validate this hypothesis...

INTRODUCTION: Multiple reports of bacterial isolates in human disc tissue have suggested a role of low-grade infection on intervertebral disc degeneration (IDD) and Modic Changes (MC) generation. Animal models have been extensively used to study IDD; however, until recently, no consideration had been given to eventual infectious processes. To reproduce the phenomena by inoculating an infecting agent would support the infectious hypothesis. Therefore, we studied the effect of Propionibacterium acnes (PA)inoculation on rat tails and determined whether it would produce MCs on the adjacent endplates...
