    When Acne is Not Acne.
    Dermatol Clin 2016 Apr;34(2):225-8
    Department of Dermatology, Icahn School of Medicine at Mount Sinai, 5 East 98 Street, 5th Floor, New York, NY 10029, USA.
    Acne vulgaris (AV) is considered a straightforward diagnosis made clinically without specific diagnostic testing. However, certain disorders may simulate AV, such as multiple small epidermal cysts or deep milia, multiple osteoma cutis, multiple small adnexal neoplasms, and follicular and/or infections characterized by multiple small papules and/or pustules such as gram-positive folliculitis, gram-negative folliculitis, Malassezia folliculitis, keratosis pilaris, and flat warts. This can lead to an erroneous diagnosis and improper management. Read More

    Differential diagnosis of facial acne on black skin.
    Int J Dermatol 2012 Nov;51 Suppl 1:24-6, 27-9
    The diagnosis of acne is usually easy, but there are some pitfalls to be avoided. 'Keloid acne of the neck' and beard folliculitis are not acnes in the usual sense: both are inflammatory and fibrous reactions of the hair follicles and frizzy hair; no retentional lesions, blackheads and microcysts--are visible. Gram negative folliculitis classically occurs in acneic male subjects who have undergone extensive treatment with general antibiotics or local antiseptics, but 'de novo' cases do exist. Read More

    Crit Rev Microbiol 2013 Feb 29;39(1):9-25. Epub 2012 May 29.
    Başkent University, Department of Dermatology, Adana Hospital, Adana, Turkey.
    Folliculitis is a superficial inflammation of the hair follicles, and can be observed in individuals of any age or race. The incidence of folliculitis is unknown because most patients only consult a doctor in cases of increasing lesions. There are various infectious and non-infectious causes of folliculitis, and the most common causative agent is Staphylococcus aureus. Read More

    Current concepts in the management of bacterial skin infections in children.
    Indian J Dermatol Venereol Leprol 2010 Sep-Oct;76(5):476-88
    Department of Dermatology, Venereology and Leprosy, SBMP Medical College, Hospital and Research Center, BLDE University, Bijapur, Karnataka, India.
    Bacterial skin infections in children vary widely clinically, starting from mild superficial folliculitis to deep necrotizing fasciitis. The causative organisms are mostly Staphylococcus aureus and Streptococcus, with occasional involvement of Gram-negative organisms. Treatment of even the milder forms of bacterial skin infections is of importance because of the long-term morbidity associated with them. Read More

    Induction of inflammatory reactions by lipopolysaccharide in hamster sebaceous glands and pilosebaceous units in vivo and in vitro.
    Exp Dermatol 2010 Dec 18;19(12):1107-9. Epub 2010 Aug 18.
    Lipopolysaccharide (LPS) from Gram-negative bacteria has been reported to exert inflammatory reactions in epidermis, dermis, and sebaceous glands. Here, we demonstrated that the intradermal administration of Escherichia coli-derived LPS, three times a week for 4 weeks, to hamster auricle skin did not influence sebaceous morphology or sebum accumulation in sebaceous glands but in fact induced epidermal thickness. In addition, the administration of LPS, once a day for 2 days, augmented the production of cyclooxygenase 2 (COX-2) in sebaceous glands. Read More

    PCR analysis for Wolbachia in human and canine Demodex mites.
    Arch Dermatol Res 2009 Oct 4;301(10):747-52. Epub 2009 Aug 4.
    Department of Dermatology and Allergology, Ludwig-Maximilian-University, Munich, Germany.
    In many skin diseases such as Demodex folliculitis, rosacea- or steroid-induced rosacea Demodex mites are present in abundance and are at least partially held responsible for causing these disorders. Although it is known that these diseases respond well to tetracyclines, it is unclear if this is due to the antiinflammatory effects of the antibiotics or to an antibacterial effect on so far unknown bacteria within the Demodex mites. As in filariasis, where the response to doxycycline can be explained by the presence of Wolbachia within the filarial nematodes, this study was performed to see whether Wolbachia also use Demodex mites as their hosts.

    J Dtsch Dermatol Ges 2006 Apr;4(4):293-300
    Department of Dermatology and Venereology, Technical University of Munich, Germany.
    Benzoyl peroxide (BPO) was introduced in the treatment of acne in 1934. Despite the fact that only few randomized trials have been published, BPO is considered the standard in topical acne treatment. Anaerobic bacteria are reduced by oxidative mechanisms and the induction of resistant strains is reduced. Read More

    Update on treating uncomplicated skin and skin structure infections.
    J Drugs Dermatol 2005 Nov-Dec;4(6 Suppl):s9-14
    Baylor College of Medicine, Houston, TX 77030-2725, USA.
    Dermatologists treat a variety of uncomplicated skin and skin structure infections (uSSSIs) such as folliculitis, impetigo, erysipelas, cellulitis, furuncles, carbuncles, and non-perirectal abscesses. Most uSSSIs are caused by Staphylococcus aureus and Streptococcus pyogenes. The new extended-spectrum cephalosporins (cefdinir, cefpodoxime) offer efficacy against most Gram-positive and Gram-negative pathogens. Read More

    Bacterial diseases of the skin.
    J Long Term Eff Med Implants 2005 ;15(5):499-510
    University of Virginia Health System, Charlottesville, Virginia, USA.
    When considering common bacterial diseases of the skin, rather distinct clinical responses to a variety of bacterial infections have been identified. In these cases, it is the specific site of infection and the attendant inflammatory responses that provide the characteristic clinical picture. When the pyoderma extends just below the stratum corneum, it is called impetigo. Read More

A wide variety of SSSIs exist, with cellulitis, impetigo and folliculitis being the most common. Most SSSIs are caused by aerobic staphylococci and streptococci, with aerobic Gram-negative bacilli and anaerobes being involved in more complicated infections. Read More

    Antibacterial therapy for acne: a guide to selection and use of systemic agents.
    Am J Clin Dermatol 2003 ;4(5):307-14
    National Skin Centre, Singapore.
    Acne vulgaris is a very common disorder, affecting virtually every adolescent at some point in time. Systemic antibacterials have been used in the treatment of acne for many years, and there are several commonly used antibacterials which have established efficacy and safety records. In recent years, the issue of antibacterials resistance has become more prominent, especially with concerns that Propionibacterium acnes can transfer antibacterials resistance to other bacteria within the resident skin flora.

    Treatment of gram-negative folliculitis in patients with acne.
    Am J Clin Dermatol 2003 ;4(4):273-6
    Department of Dermatology, University Hospital, Zürich, Switzerland.
    Gram-negative folliculitis may be the result of long-term antibacterial treatment in acne patients. It is caused by bacterial interference and replacement of the Gram-positive flora of the facial skin and the mucous membranes of the nose and infestation with Gram-negative bacteria. These Gram-negative bacteria include Escherischia coli, Pseudomonas aeruginosa, Serratia marescens, Klebsiella and Proteus mirabilis. Read More

    Utah Valley Family Practice Residency, Provo 84604, USA.
    Family physicians frequently treat bacterial skin infections in the office and in the hospital. Common skin infections include cellulitis, erysipelas, impetigo, folliculitis, and furuncles and carbuncles. Cellulitis is an infection of the dermis and subcutaneous tissue that has poorly demarcated borders and is usually caused by Streptococcus or Staphylococcus species. Read More

    Citrobacter koseri in scalp folliculitis.
    Cutis 2002 May;69(5):393-4
    Department of Dermatology, Hospital Universitario de Canarias, University of La Laguna, Tenerife, Canary Islands, Spain.
    Gram-negative folliculitis, an uncommon condition, is most often seen in older patients who have acne and who either have received prolonged courses of antibiotic therapy or have used antibacterial cleansers that selectively inhibit gram-positive organisms. Citrobacter infections are uncommon, and dermatologists seldom encounter them. In the past, these infections occurred in hospitals, particularly in neonatal intensive care units. Read More

    Skin microflora and bacterial infections of the skin.
    J Investig Dermatol Symp Proc 2001 Dec;6(3):170-4
    Department of Dermatology, University of California at San Francisco, USA.
    The skin is a milieu for controlled bacterial growth. Skin supports the growth of commensal bacteria, which protect the host from pathogenic bacteria. Environmental and local factors, host immunity, and organism adherence and virulence are intricately related to cutaneous infection. Read More

    Methods: The bacteriologic and immunologic findings are reported in 46 patients, 39 men and 7 women, aged 16-79 (median, 28) years, with gram-negative folliculitis. Hypersensitivity reactions to various microbial recall antigens as well as granulocyte functions were evaluated. Read More

    Bacterial skin infections at a tertiary dermatological centre.
    Singapore Med J 1998 Aug;39(8):353-6
    National Skin Centre, Singapore.
    Background: Bacterial skin infections are common clinical problems encountered in most fields of clinical medicine. Staphylococcus aureus and group A streptococci are common invaders of eczematous, traumatised or immunocompromised skin. Advances in pharmacology have introduced a wide array of new antibiotics into the physician's armamentarium, but the rising incidence of bacterial resistance continues to be a problem. Read More

    Oral isotretinoin treatment policy. Do we all agree?
    Dermatology 1997 ;195 Suppl 1:34-7; discussion 38-40
    Service de Dermatologie, Hôpital de l'Archet, Nice, France.
    A consensus meeting was held in Brussels in 1995 to review current oral isotretinoin (Roaccutane/Accutane) treatment policies among internationally renowned experts and to improve service to needy patients by proposing treatment guidelines based upon a review of 1,000 acne patients who received this therapy. The group agreed that acne conditions warranting oral isotretinoin treatment include severe acne and poorly responsive acne which improves less than 50% after 6 months of therapy with combined oral and topical antibiotics. Furthermore, acne which relapses, scars or induces consequential psychological distress should be treated with oral isotretinoin. Read More

    New cutaneous manifestations of systemic diseases.
    Am Fam Physician 1995 Feb;51(3):625-30
    Mount Sinai Medical Center, New York, New York.
    In recent years, especially with the advent of acquired immunodeficiency syndrome, new skin disorders associated with systemic disease have been described in the literature. Eosinophilic folliculitis and pruritic papules of human immunodeficiency virus (HIV) infection are clinically similar lesions that respond to phototherapy. Bacillary angiomatosis, another HIV-related skin disease that is caused by a pleomorphic gram-negative organism, resembles Kaposi's sarcoma clinically but is curable if treated early with antibiotics.

    Loofah sponges as reservoirs and vehicles in the transmission of potentially pathogenic bacterial species to human skin.
    J Clin Microbiol 1994 Feb;32(2):469-72
    Clinical Microbiology Laboratories, Mount Sinai Hospital, New York, New York 10029.
    Loofah sponges are natural products used as exfoliative beauty aids. As a consequence of tracing a case of Pseudomonas aeruginosa folliculitis to a contaminated loofah sponge, we assessed the role of loofah sponges in supporting the growth of a wide variety of bacterial species. Our data show growth enhancement of sterile loofah fragments for numerous gram-negative (Pseudomonas, Xanthomonas, and Klebsiella) and gram-positive (Enterococcus and group B Streptococcus) species of human and environmental origin.
