INTRODUCTION
Lichen simplex chronicus has been defined as a localized skin condition characterized by thickening, hyperpigmentation and accentuated skin markings from chronic itching and from repeated scratching. The affected skin area is usually described as demarcated, and often circumscribed. It has even been defined as a "psychogenic pruritic disorder". The idea of a neurological component has also been suggested, hence the term 'neurodermatitis circumscripta'. However, the pathophysiology of this condition remains unclear. Several associations and etiologies have been reported in literature, including strong links with mental disorders-anxiety and obsessive compulsive disorder to be specific. We report this case, most importantly, to highlight the value of an open-minded approach to patients and the 'old-fashioned' physician character of empathy, the skill of detailed history taking and physical examination, and lastly to suggest that lichen simplex chronicus may not always present as a localized, 'circumscripta' or demarcated area of skin.
CASE DESCRIPTION
When a sixty-five year-old Caucasian female presented to our clinic agitated, intensely scratching her entire body and complaining of severe pruritus, an open-minded detailed approach during history taking and physical examination led to the working diagnosis of diffuse lichenification from chronic scratching secondary to a "possible" cutaneous disorder. Her medical history was unremarkable, but her psychiatric history was significant for Anxiety disorder. She remained on her anxiolytic medication. Her presenting symptom was reported to have persisted for more than 9 months. Review of previous unremarkable lab results and a remarkable findings on detailed skin inspection led to an empiric, trial regimen consisting of three topical preparations: an anti-pruritic-to break the itch-scratch cycle, anti-inflammatory-to curb any inflammatory/immune response and a 'last-ditch' scabicidal application. Follow-up was scheduled, but the patient called the office requesting an earlier follow up appointment. The lesions had significantly improved and the hyper-pigmented, indurated and escoriated skin appearance had resolved; and most importantly, the pruritus.
CONCLUSION
Thus we conclude that lichen simplex chronicus may not always present as circumscribed or localized area of skin as currently noted in literature. Also, in patients with psychiatric conditions including anxiety and obsessive-compulsive disorder in particular, effort should be made to avoid stereotyping their presentation as part of their mental disorder spectrum. The value of detailed history and physical examination, mixed with empathy is highlighted. We make our recommendation considering the profound turnaround in the patient's condition and quality of life after several months of emotional and psychological suffering.

Neurofibromatosis type 1 (NF1) is one of the most common tumor predisposition syndromes which primarily affects the skin. NF1 is characterized by various degrees of skin tumors and pigmentation abnormalities such as café-au-lait macules. Other skin diseases, such as psoriasis or neurodermatitis, have a negative influence on sexuality and quality of life and represent a psychological burden for those affected. The present study investigated the extent to which skin tumors (disfigurement) are related to sexuality and psychosocial factors in NF1 individuals. An anonymous online survey was carried out on Facebook and the webpage of the German Neurofibromatosis Association and a total of 166 persons participated. Of these participants, 92 were affected by NF1.74 healthy persons took part in the survey as a comparative group. Results show a significant relation between sexuality, body image, quality of life and the presence of depressive symptoms of the NF1 affected persons. Individuals with NF1 show a more negative sexual self-esteem. These concerns should be taken into account in NF1- related health care approaches.

BACKGROUND
This case report demonstrates the value of ultrasound measurements, and immunological and toxicological diagnostics in addition to current x-ray imaging procedures to diagnose hidden oral and maxillofacial infections. Using a clear scheme shows the procedure of the authors' steps. The positive impact on the patient's dermatological clinical picture is shown. Functional regeneration using metal-free ceramic implants and autologous bone augmentation is demonstrated. After a healing period, a postoperative control took place.
QUESTION
Are chronic inflammatory and chronic toxic stressors from the oral region affecting the patient's state of health and dermatological symptoms?
PATIENTS AND METHODS
A 52 year old female suffering from neurodermatitis, who had been therapy-resistant for several years, was rehabilitated by oral surgery and prosthetics. Radiological examinations with orthopantomogram (OPG) and three-dimensional imaging (DVT/CBCT) were inconclusive for possible jawbone inflammatory sites. Immunological, toxicological diagnostics and trans-alveolar bone densitometry with ultrasound (TAU), were able to show immunological and toxicological stressors and areas of reduced bone density. Bone densitometry with ultrasound raised the suspicion of silent inflammations in the jawbone with potentially increased cytokine levels.
RESULTS
For the patient incompatible materials, teeth with increased toxin exposure and surrounding softened, fatty, ischaemic bone was removed. Histologies and cytokine profiles were obtained. The resulting defects were functionally regenerated using ceramic implants and autologous augmentation. The cytokine profiles showed significantly elevated RANTES/CCL5, confirming the need for surgical intervention. The patient's atopic dermatitis improved significantly in this case.
SUMMARY
Individualized immunological and toxicological diagnostics and trans-alveolar bone density bone densitometry with ultrasound (TAU) identified immunological and toxicological stressors as well as reduced bone density with increased cytokine levels. A therapy-resistant neurodermatitis improved significantly after treatment.
CONCLUSION
This case report illustrates the need for patient-specific and individualized examinations that link dentistry more closely with other medical conditions in order to clarify possible interactions.

Meta-Analysis Review
BACKGROUND
The lack of standardized nomenclature for atopic dermatitis (AD) creates unnecessary confusion for patients, healthcare providers, and researchers. It also negatively impacts accurate communication of research in the scientific literature. We sought to determine the most commonly used terms for AD.
METHODS
A systematic review of the MEDLINE, EMBASE, and LILACS (1945-2016) for the terms AD, atopic eczema (AE), and multiple other eczematous disorders.
RESULTS
In MEDLINE, 33 060 were identified, of which 21 299 (64.4%) publications used the term 'AD', 15 510 (46.9%) 'eczema', and only 2471 (7.5%) AE. Most of these publications used the term AD (82.0%) or eczema (70.8%) without additional nomenclature; only 1.2% used AE alone. Few publications used the terminology 'childhood eczema', 'flexural eczema', 'infantile eczema', 'atopic neurodermatitis', or 'Besnier's prurigo'. AD was rarely used until the late 1970s, after which it became the most commonly used of the three terms and continuously increased until 2015. Atopic eczema decreased between 2008 and 2015. Atopic dermatitis was the most commonly used term in studies across almost all publication types, languages, and journals.
CONCLUSION
Atopic dermatitis is the most commonly used term and appears to be increasing in popularity. Given that eczema is a nonspecific term that describes the morphological appearance of several forms of dermatitis, we strongly suggest the use of a more specific term, AD, in publications, healthcare clinician training, and patient education. Support from researchers, reviewers, and editors is key to success.

BACKGROUND
Hypertrophic lichen planus (HLP) classically involves shin and ankles and is characterized by hyperkeratotic plaques and nodules. Prurigo nodularis (PN) is a chronic neurodermatitis that presents with intensely pruritic nodules. Histopathology of HLP and PN demonstrate epidermal hyperplasia, hypergranulosis, and compact hyperkeratosis. The dermis shows vertically arranged collagen fibers and an increased number of fibroblasts and capillaries in both conditions. Moreover, basal cell degeneration is confined to the tips of rete ridges, and band-like infiltration is conspicuously absent in HLP. Therefore, both conditions mimic each other clinically, which makes diagnosis difficult. Hence, there is a need for a diagnostic technique to differentiate both conditions.
OBJECTIVE
To evaluate dermoscopic patterns in HLP and PN and to study these patterns histopathologically.
MATERIALS AND METHODS
The study was conducted at S. Nijalingappa Medical College in Bagalkot. It was an observational case series study. Ethical clearance and informed consent was obtained. A Dermlite 3 dermoscope (3Gen, San Juan Capistrano, CA, USA) attached to a Sony Cyber Shot camera DSC-W800 (Sony Electronics Inc., San Diego, California, USA) was employed. Histopathology was done to confirm the diagnosis.
RESULTS
There were 10 patients each with HLP and PN. HLP was seen in 8 males and 2 females. PN was observed in 7 females and 3 males. Dermoscopy of HLP demonstrated pearly white areas and peripheral striations (100%), gray-blue globules (60%), comedo-like openings (30%), red dots (40%), red globules (10%), brownish-black globules (30%), and yellowish structures (90%). In PN, red dots (70%), red globules (60%), and pearly white areas with peripheral striations (100%) were observed under dermoscopy.
CONCLUSION
Both HLP and PN demonstrated specific dermoscopic patterns which can be demonstrated on histopathologic findings. The authors propose that these patterns are hallmarks of each condition. Thus, dermoscopy is a good diagnostic tool in the differentiation of HLP and PN.

A long-term review of 108 women suffering from various forms of vulval dermatosis is described and a detailed analysis of those with chronic hypertrophic vulvitis, lichen sclerosus et atrophicus, and neurodermatitis is made. One case of neurodermatitis and two cases of lichen sclerosus progressed to carcinoma but no case of chronic hypertrophic vulvitis became malignant. It is possible that vulval dermatoses occur more commonly in the nulliparous than in the parous women and there is a slight preponderance of women who are blood group A. It is suggested that the term "leukoplakia" should be abandoned and that vulval lesions should be described in precise and meaningful histological terms.

The tissues affected by histamine and anaphylactic reactions are identical. Epinephrine antagonizes the action of histamine by acting on effector cells in a direction opposite to that of histamine. The so-called antihistaminic drugs block rather than antagonize the action of histamine. The injection into the human body of epinephrine or certain antihistaminic substances provokes the release of histamine and thereby produces a rise in the histamine blood level. There is a remarkable conformity of potency of antihistaminics as determined by Dale experiments and by histamine intoxication experiments in the intact guinea pig. Neoantergan, Pyribenzamine and Histadyl are usually superior to other compounds when potency is assayed by these methods. All antihistaminics provide similar protection again animal anaphylaxis. Larger doses are necessary to protect against anaphylaxis than against histamine intoxication. The differences in potency as determined by Dale experiments and histamine experiments in animals are not found in clinical use. One compound is not generally superior to all others in the treatment of any one or several allergic disorders. The antihistaminic drugs are beneficial in the symptomatic treatment of allergic rhinitis, acute urticaria and angioneurotic edema, and mild non-infective bronchial asthma. Their effectiveness in the management of moderately severe and severe non-infective bronchial bronchial asthma; infective bronchial asthma; migraine; atopic dermatitis (disseminated neurodermatitis), and pruritus of skin disorders other than acute urticaria and angioneurotic edema, is not worthy of particular commendation. The size of the dose of any antihistaminic substance influences the incidence of but not the type of side-effect that may accompany its usage. The quality of side effects varies according to the drug, although there is an individuality of response for each patient which must be reckoned with. In selecting an antihistaminic compound it is necessary to consider the percentage of cases in which side effects occur, as well as the percentage of good results. Optimal results are obtained by employing combinations of compounds and changing from one to the other as the case demands.

The use of corticosteroids systemically in dermatology has benefited patients with pemphigus and systemic lupus erythematosus in that they now have a better chance to carry on a productive life. These hormones, used cautiously, can alleviate some of the tremendous suffering during the explosive exacerbations and acute crises of atopic and neurodermatitis. Corticosteroids are useful in the widespread and acute contact dermatitis and drug eruptions; they are contraindicated in the treatment of ordinary psoriasis. Every attempt should be made by history-taking, clinical examination and necessary laboratory studies to reach an accurate diagnosis before corticosteroids are used. If use of them is indicated, then total patient care is required to avoid complications, and a very careful follow-up is mandatory.
