    Proposing a Simpler Classification of Telogen Effluvium.
    Skin Appendage Disord 2016 Sep 18;2(1-2):35-38. Epub 2016 May 18.
    Department of Dermatology, University of Genoa, Genoa, Italy.
    Telogen effluvium (TE) is a pathogenically heterogeneous condition which so far has been classified into acute and chronic forms - or, according to Headington, into 5 different pathogenetic forms. Regrettably, Headington's classification is difficult to apply in the office, and most papers dealing with TE ignore it. The present review intends to propose a novel classification of TE and to introduce, tentatively, a new variety of TE. Read More

    Traditional Anticoagulants and Hair Loss: A Role for Direct Oral Anticoagulants? A Review of the Literature.
    Drugs Real World Outcomes 2016 Mar;3(1):1-6
    King's Thrombosis Centre, Department of Haematological Medicine, King's College Hospital, London, UK.
    Hair loss is associated with the anticoagulants heparin and warfarin. With the recent availability of direct oral anticoagulants (DOACs) it is of clinical interest to know if they are implicated with hair loss and/or whether they could be successfully prescribed for patients who suffer from coumarin- or heparin-related alopecia. Initially reports of heparin- and coumarin-associated alopecia available through PubMed and Medline were explored in order to establish the cause of this side effect. Read More

    Vitamin and Mineral Deficiencies in Patients With Telogen Effluvium: A Retrospective Cross-Sectional Study.
    J Drugs Dermatol 2016 Oct;15(10):1235-1237
    Telogen effluvium is one of the most common forms of non-scarring alopecia for which patients present to a dermatologist. It is a challenging disorder to treat and study, primarily owing to its multifactorial etiology which includes both physiologic and non-physiologic factors. Nutritional deficiency has been purported to contribute to hair shedding, and a patient's clinical history usually aids in directing laboratory evaluation. Read More

    Eccrine Duct Dilation as a Marker of Cicatricial Alopecia.

    Apoptosis May Explain the Pharmacological Mode of Action and Adverse Effects of Isotretinoin, Including Teratogenicity.
    Acta Derm Venereol 2017 Feb;97(2):173-181
    Department of Dermatology, Environmental Medicine and Health Theory, University of Osnabrück, DE-49076 Osnabrück, Germany.
    Isotretinoin (13-cis retinoic acid) is the most effective sebum-suppressive drug for the treatment of severe acne. Its effect depends on sebocyte apoptosis, which results from isotretinoin-induced expression of the apoptotic protein tumour necrosis factor-related apoptosis-inducing ligand, insulin-like growth factor-binding protein-3 and neutrophil gelatinase-associated lipocalin. This review proposes that the pharmacological mode of action of isotretinoin in the treatment of severe acne, acute promyelocytic leukaemia, and neuroblastoma results from apoptosis. Read More

    Hormones and clocks: do they disrupt the locks? Fluctuating estrogen levels during menopausal transition may influence clock genes and trigger chronic telogen effluvium.
    Dermatol Online J 2016 May 15;22(5). Epub 2016 May 15.
    Departments of Dermatology: The Permanente Medical Group (Vallejo, CA), University of California, San Francisco, Case Western Reserve University.
    Chronic telogen effluvium describes the clinical condition noted mostly in middle-aged women of increased, diffuse scalp hair shedding that is prolonged and often presents with a fluctuating course that may continue for years but does not lead to visible hair thinning. Despite its description almost 20 years ago, the underlying pathologic cause of CTE is yet to be identified. However the culmination of research in the field of hair biology and the burgeoning field of chronobiology may lead to exciting breakthroughs in our understanding of CTE. Read More

    Serum Biotin Levels in Women Complaining of Hair Loss.
    Int J Trichology 2016 Apr-Jun;8(2):73-7
    Center for Dermatology and Hair Diseases Professor Trüeb, Zurich-Wallisellen, Switzerland.
    Biotin is a coenzyme for carboxylase enzymes that assist various metabolic reactions involved in fatty acid synthesis, branched-chain amino acid catabolism, and gluconeogenesis important for maintenance of healthy skin and hair. Due to its availability, affordability, and effective marketing for this purpose, biotin is a popular nutritional supplement for treatment of hair loss. However, there are little data on the frequency of biotin deficiency in patients complaining of hair loss and on the value of oral biotin for treatment of hair loss that is not due to an inborn error of biotin metabolism or deficiency.

    Telogen elongation in the hair cycle of ob/ob mice.
    Biosci Biotechnol Biochem 2015 4;80(1):74-9. Epub 2015 Aug 4.
    a Department of Gerontological Nursing/Wound Care Management, Graduate School of Medicine , The University of Tokyo , Tokyo , Japan.
    Alopecia impairs the physical and mental health of patients. We have previously shown that 8-week-old ob/ob mice have no reactivity to depilation, which is a stimulus that induces anagen transition in normal mice, while no hair cycle abnormalities have been reported in other studies until mice reach 7 weeks of age. Therefore, we hypothesized that ob/ob mice have abnormalities in hair cycle progression beyond 7 weeks of age. Read More

    Psoriatic alopecia.
    Clin Exp Dermatol 2015 Oct 23;40(7):717-21. Epub 2015 Jul 23.
    Department of Dermatology, Brighton and Sussex University Hospitals NHS Trust, Brighton, UK.
    Alopecia and other hair abnormalities occurring in patients with psoriasis were first recognized over four decades ago, yet psoriatic alopecia is not a well-known concept among clinicians. Alopecia may be directly related to the psoriasis itself, and can affect both the scalp and other parts of the body. On the scalp, psoriatic alopecia most commonly affects lesional skin, but may present as a generalized telogen effluvium. Read More

    Actas Dermosifiliogr 2015 Apr 25;106(3):158-67. Epub 2014 Oct 25.
    Servicio de Dermatología, Fundación Jiménez Díaz, Universidad Autónoma de Madrid, Madrid, España.
    The diagnosis of disorders of the hair and scalp can generally be made on clinical grounds, but clinical signs are not always diagnostic and in some cases more invasive techniques, such as a biopsy, may be necessary. This 2-part article is a detailed review of the histologic features of the main types of alopecia based on the traditional classification of these disorders into 2 major groups: scarring and nonscarring alopecias. Scarring alopecias are disorders in which the hair follicle is replaced by fibrous scar tissue, a process that leads to permanent hair loss. Read More

    Telogen effluvium as the first symptom of Crohn's disease in a child.
    Ann Gastroenterol 2014 ;27(4):418-420
    Pediatric Gastroenterology Unit (Maria Rogalidou, Meropi Tzoufi, Antigoni Siamopoulou-Mavridou), University Hospital of Ioannina, Greece.
    Crohn's disease usually manifests gastrointestinal symptoms, however in some cases the patient presents with prominent or even exclusive extraintestinal involvement. Alopecia has been reported as a complication of therapeutic agents used in the treatment of inflammatory bowel disease, and, in a few cases of adult patients, prior to the appearance of gastrointestinal symptoms. We present a 10 year-old-child with telogen effluvium that appeared one year before the diagnosis of Crohn's disease, as the first and only symptom at that time. Read More
