BACKGROUND: The histologic findings of scalp involvement in dermatomyositis are not well characterized due to lack of large series. OBJECTIVE: To systematize the histologic features of scalp involvement in dermatomyositis on horizontal and vertical sections. MATERIALS AND METHODS: A descriptive, prospective, cross-sectional study recruited 31 patients with pathologically and serologically confirmed dermatomyositis in Mexico City from June 2014 to June 2015...

Throughout pregnancy, the body undergoes a variety of physiologic changes. The cutaneous findings can be most noticeable and often worrisome to both physicians and patients. Obstetricians and dermatologists must be able to differentiate between changes that are benign and those that may be pathologic. Most physicians recognize benign changes that are commonly described in literature such as hyperpigmentation, melasma, striae gravidarum, and telogen effluvium; however, they may be unaware of changes that tend to be less frequently discussed...

Non-scarring hair loss is a common problem that affects both male and female patients. Since any disturbances in the hair follicle cycle may lead to hair shedding, or alopecia, it is not surprising that the possible role of vitamin D in alopecia was investigated in many studies. Vitamin D has been shown to have many important functions. A growing body of evidence shows that vitamin D and its receptor are responsible for maintaining not only calcium homeostasis but also skin homeostasis. Moreover, vitamin D could also regulate cutaneous innate and adaptive immunity...

There has been a resurgence of syphilis in the last decade. Although alopecia is not a common manifestation of the disease, the "moth-eaten" pattern is considered patognomonic. However, diffuse hair loss, termed essential alopecia, sometimes can be the only sign of syphilis infection and mimic other conditions, such as alopecia areata and telogen effluvium. We describe three patients with syphilis in whom the pattern of alopecia was not typical. Although clinical, histopathological, and trichoscopic examinations may share some similar findings with other hair diseases, the inclusion of syphilis in the differential diagnosis of hair loss causes is fundamental to a correct screening and diagnosis...

Contrary to the classical view of the hair cycle, in which telogen is the resting phase that precedes the release of the hair shaft, another phase has been introduced, exogen. Exogen is the phase wherein the processes for the release of the hair shaft are initiated and successfully executed. Exogen ends when the shaft is liberated. Accordingly, human hairs would be preferably released not with telogen but with exogen roots. To better understand this somehow revolutionary point and what occurs in telogen effluvium (TE) and in androgenetic alopecia (AGA), we undertook a morphological study...

Background : Chronic telogen effluvium (CTE) may be primary or secondary to various causes, including drug reaction, nutritional deficiency and female pattern hair loss (FPHL).  Oral minoxidil stimulates hair growth, and topical minoxidil is used in the treatment of FPHL and male androgenetic alopecia. minoxidil has not been used to treat CTE. This study aimed to assess the treatment of CTE with once daily oral minoxidil. Methods : Women with a diagnosis of CTE based on >6 month history of increased telogen hair shedding, no visible mid frontal scalp hair loss (Sinclair stage 1) and no hair follicle miniaturization on scalp biopsy were treated with once daily oral minoxidil...

Psychotrichology is the science, which covers the psychosomatics applied to hair problems, i.e., body-psyche phenomena involving scalp and hair disorders. The approaches involving psychotricology are varied and may include psychiatric,[1] psychoanalytical,[23] and those involving knowledge related to analytical psychology.[4] An analysis from the analytical psychology point of view, a theory developed by the physician Carl Gustav Jung, favors a symbolic view to the disease, providing it attributions and meanings that go beyond those related to physical body signs and symptoms only...

BACKGROUND: Focal atrichia is a common clinical finding in female pattern hair loss whose specificity and histologic findings need further clarification. OBJECTIVE: To determine the frequency of focal atrichia in various types of hair loss and its histologic characteristics in female pattern hair loss. METHODS: Part 1: Review of 250 consecutive female patients seen with hair loss for the presence of focal atrichia and Part 2: paired biopsies of haired areas vs focal atrichia in 18 subjects with female pattern hair loss RESULTS: Focal atrichia was seen in 46/104 (44%) of women with female pattern hair loss, including 67% of late onset vs 15% of early onset, compared to 3/146 (2%) of those with other hair disorders Biopsy findings of focal atrichia in female pattern hair loss showed primarily a more progressive miniaturization process than that of haired areas of the scalp...

BACKGROUND: Nutritional deficiencies are known to be associated with hair loss; however, the exact prevalence is not known. AIMS: The aim of this study is to evaluate the prevalence of nutritional deficiencies in participants with hair loss. MATERIALS AND METHODS: In this cross-sectional study, 100 enrolled participants were divided into telogen effluvium (TE), male-pattern hair loss (MPHL), and female-pattern hair loss (FPHL) based on the type of hair loss...

Hair loss is often distressing and can have a significant effect on the patient's quality of life. Patients may present to their family physician first with diffuse or patchy hair loss. Scarring alopecia is best evaluated by a dermatologist. Nonscarring alopecias can be readily diagnosed and treated in the family physician's office. Androgenetic alopecia can be diagnosed clinically and treated with minoxidil. Alopecia areata is diagnosed by typical patches of hair loss and is self-limited. Tinea capitis causes patches of alopecia that may be erythematous and scaly and must be treated systemically...

BACKGROUND: Accurate identification of follicular streamers versus follicular scars on horizontal scalp biopsy sections is important to differentiate between cicatricial and noncicatricial alopecias. However, distinguishing between them can be difficult especially in nonoptimal specimens. The utility of elastic Verhoeff-Van Gieson (EVG) stain in cicatricial alopecias has been described on vertical sections, but its evaluation on horizontal sections has not been performed. METHODS: Sixty-four cicatricial alopecias (25 lichen planopilaris, 29 central centrifugal cicatricial alopecias, and 10 discoid lupus erythematosus) and 53 noncicatricial alopecias (34 androgenic alopecia, 8 telogen effluvium, and 11 alopecia areata) were identified, and EVG staining was performed on horizontal sections...

BACKGROUND: Telogen effluvium (TE) is a type of acquired, diffuse alopecia that occurs due to an abnormal shift of scalp hair follicles from anagen to telogen, leading to premature shedding of hair. Previous studies have suggested the existence of a neuroimmunologic "brain-hair follicle" axis, in which mast cells have been implicated as an important link between the nervous system and immunologic system. OBJECTIVE: The current study sought to investigate the role of mast cell presence and mast cell degranulation in the pathogenesis of TE...

Mesotherapy (from Greek meso = in between, therapeia = treat) is a non-surgical, mostly cosmetic therapy, where active substances are injected intradermally into a depth of about 4 mm. It is an effective and easy-to-use method in the treatment of alopecia. It is effective both in the therapy of androgenetic alopecia and telogen effluvium. In recent years, it has been massively expanded also among non-medical fields, which has caused its contradictory perception by professional medical circles outside dermatologists...

Chronic telogen effluvium is most often intermittent, alternating periods of spontaneous remissions with episodes of unexplained relapses. This article reports the case of a male who was able to graphically depict the sequence of emotional events and the corresponding severity of his telogen effluvium during 31 months. The case is interesting as it documents for the first time the intermittency of chronic telogen effluvium and the pathogenetic role of emotional strains, and it stresses the importance of the modified wash test in evaluating the severity of hair shedding...

BACKGROUND: Androgenetic alopecia (AGA) is a patterned hair loss occurring due to systemic androgen and genetic factors. It is the most common cause of hair loss in both genders. In recent years, many studies investigating the relation between systemic diseases and androgenetic alopecia presented controversial results. OBJECTIVES: In this study we aimed to investigate the frequency of androgenetic alopecia, the presence of accompanying systemic diseases, the relation between body mass index and androgenetic alopecia severity and the association of hyperandrogenemia signs with androgenetic alopecia in patients who referred to our outpatient clinic...

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. Three pathogenetic types of TE can be identified, whose common clinical element is the profuse shedding of hairs: (1) premature teloptosis, (2) collective teloptosis, and (3) premature entry into the telogen phase...

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. Currently there is a lack of unanimity on why anticoagulants cause alopecia...
