Scalp dysaesthesia and lichen simplex chronicus: diagnostic and therapeutic update with literature review.

Scalp dysaesthesia, considered a variant of the cutaneous dysaesthesia syndrome, is characterized by chronic sensory symptoms, including pruritus, pain, burning and stinging in a well-defined location, without objective findings. Its aetiology is not well elucidated and treatment options are limited, thus it can be challenging and frustrating for both patient and physician. It can be associated with lichen simplex chronicus. In this paper, we review the literature on the pathogenetic factors, diagnostic methods and therapeutic options in the management of scalp dysaesthesia. Dissociation, cervical spine disease and muscle tension seem to be the most important pathogenetic factors. Trichoscopy, reflectance confocal microscopy and biopsy are all helpful for the diagnosis of the disease. Therapies include high-potency topical or intralesional corticosteroids, capsaicin and topical anaesthetics, sedative antihistamines, tricyclic antidepressants, transcutaneous electric nerve stimulation, botulinum toxin and vitamin B12.

Comparison of efficacy and safety of high-intensity focused ultrasound at different powers for patients with vulvar lichen simplex chronicus.

OBJECTIVE: To compare the efficacy and safety of the treatment of vulvar lichen simplex chronicus (VLSC) using high-intensity focused ultrasound (HIFU) at different powers. METHODS: This retrospective study included 152 patients with VLSC. Among these patients, 70 were treated with HIFU at low power (level 2), and 82 were treated at normal power (level 3). The treatment responses, recurrence rates and intra- and postoperative complications were all compared. RESULTS: No statistically significant differences were found between the two groups in age, disease course, menopause status, lesion size and severity of symptoms. All patients received one session of HIFU therapy, and the treatment process was successful. No difference was found in the total response rate between the two groups at 1 (85.7% versus 87.8%, p = .35), 6 (80% versus 80.5%, p = .65) and 12 (80% versus 80.5%, p = .73) months after HIFU therapy. No significant difference was observed in the recurrence rate between the two groups at 6 (5.7% versus 9.8%, p = .36) and 12 (22.9% versus 26.8%, p = .57) months after HIFU treatment. Patients in the low-power group had a lower incidence of blisters (10% versus 23.3%, p = .04). CONCLUSION: Based on our results, low-power HIFU treatment can achieve a therapeutic effect similar to normal power HFU treatment for VLSC, but its incidence of side effects is lower.

Patterns of Skin Disease in the Context of a High Prevalence HIV Population in Botswana.

The authors reviewed outpatients in a tertiary dermatology clinic in Botswana to expand knowledge on patterns of skin disease in this population with a high prevalence of human immunodeficiency virus (HIV). Approximately one-third of new and follow-up patients were HIV positive. Common dermatologic conditions included eczematous eruptions, viral and fungal infections, malignant neoplasms, vascular disorders, disorders of pigmentation, and mechanical/physical injury-related disorders. HIV has impacted patterns of dermatologic disease in Botswana, with Kaposi sarcoma being the most frequently biopsied condition. Given the shortage of dermatology specialists, resources should be allocated toward education and management of these most prevalent skin conditions.

Common Benign Chronic Vulvar Disorders.

Common benign chronic vulvar conditions include genitourinary syndrome of menopause (formerly called vulvovaginal atrophy), lichen sclerosus, lichen planus, lichen simplex chronicus, and vulvodynia. Genitourinary syndrome of menopause results from the hypoestrogenic state that leads to atrophy of normal vulvar and vaginal tissues. It is typically treated with lubricants, moisturizers, and intravaginal estrogen. Lichen sclerosus is an inflammatory condition characterized by intense vulvar itching. It is treated with topical steroids or, in some cases, topical calcineurin inhibitors. Patients with lichen sclerosus are at risk of vulvar squamous cell carcinoma and should be monitored closely for malignancy. Lichen planus is an inflammatory autoimmune disorder that can affect the vulva and vagina in addition to other skin and mucosal surfaces. The first-line treatment is topical steroids, and significant scarring can occur if left untreated. Lichen simplex chronicus manifests as persistent itching and scratching of the vulvar skin that leads to thickened epithelium. Breaking the itch-scratch cycle, often with topical steroids, is the key to treatment. Vulvodynia is a common vulvar pain disorder and is a diagnosis of exclusion. A multimodal treatment approach typically includes vulvar hygiene, physical therapy, psychosocial interventions, and antineuropathy medications.

Therapeutic Effects of Focused Ultrasound on Expression of Notch1, C-Fos and Transforming Growth Factor-ß3 in Vulvar Skin of SD Rats with Vulvar Lichen Simplex Chronicus.

The purpose of this study was to investigate the therapeutic effects of focused ultrasound on the expression of notch1, c-fos and transforming growth factor-ß3 (TGF-ß3) in genital skin of SD rats with vulvar lichen simplex chronicus (LSC). Fifty-six female SD rats with LSC were randomly divided into therapy and sham groups. The therapy group was exposed to focused ultrasound. The sham group received the same therapy with an instrument that had no power output. Four wk after a singly focused ultrasound therapy, histologic analyses revealed that recovered SD rats accounted for 75% of SD rats in the therapy group and 10.7% in the sham group. Total collagen fiber density in the superficial layer of dermis in the therapy group was significantly lower than that in the sham group. Notch1 and c-fos protein expression in the therapy group was significantly lower than that in the sham group, with the opposite effect present for TGF-ß3. Focused ultrasound therapy may inhibit superficial collagen fibrosis in the dermis by affecting expression of notch1, c-fos and TGF-ß3 in vulvar skin tissue and consequently reduce the recurrence rate of LSC.

Vulvar Pruritus and Lichen Simplex Chronicus.

Vulvar pruritus and lichen simplex chronicus are common reasons for presentation to women's health practitioners, including gynecologists and dermatologists. Both conditions are multifactorial and are often confounded by other inflammatory, neoplastic, infectious, environmental, neuropathic, hormonal, and behavioral variables. Careful history taking and thorough physical examinations, including wet mount and potentially skin biopsy, are necessary for appropriate diagnosis. Treatment should focus on decreasing inflammation, reducing irritants, and providing symptomatic relief to achieve remission. Comprehensive treatment covering environmental, biological, and behavioral therapy can result in long-term cure for patients with these conditions.

[Requirements for quality indicators. The relevance of current developments in outcomes research for quality management]. / Anforderungsprofil an Qualitätsindikatoren. Relevanz aktueller Entwicklungen der Outcomes Forschung für das Qualitätsmanagement.

The assessment of the health state in patients and changes in their health state for the purpose of diagnosis, prognosis and monitoring of treatment response plays a central role in clinical practice. Quality criteria for measurements in medicine include validity, reliability, responsiveness, interpretability, and feasibility. High-quality measurement instruments are a prerequisite for evidence-based medicine. Therefore, international outcomes research groups have developed methods for quality assurance and for the standardisation of measurement instruments. Quality indicators are instruments to measure the quality of care. Due to the increasing relevance of quality assessment for all stakeholders in healthcare and due to the political intention to draw relevant conclusions from the assessment of the quality of care, quality indicators must at least meet the same high standards that are required for clinical trial end points. However, independent researchers and clinicians do not engage in the validation and standardisation of quality indicators in Germany; currently, only the AQUA institute (as assigned by the German GBA) deals with this important issue. Current activities concerning the validation of quality indicators do not meet the requirements of evidence-based healthcare. This is a critical barrier to achieving the political goals of quality medicine. Therefore, the authors propose a multi-step, multi-professional, evidence-driven and evidence-generating consensus process on the basis of established methods of outcomes research for the advancement of quality assessment with quality indicators in Germany. All relevant stakeholders should participate in this process.

Recognition and management of vulvar dermatologic conditions: lichen sclerosus, lichen planus, and lichen simplex chronicus.

Lichen sclerosus, lichen planus, and lichen simplex chronicus are dermatologic conditions that can affect the vulva. Symptoms include vulvar itching, irritation, burning, and pain, which may be chronic or recurrent and can lead to significant physical discomfort and emotional distress that can affect mood and sexual relationships. With symptoms similar to common vaginal infections, women often seek care from gynecological providers and may be treated for vaginal infections without relief. Recognition and treatment of these vulvar conditions is important for symptom relief, sexual function, prevention of progressive vulvar scarring, and to provide surveillance for associated vulvar cancer. This article reviews these conditions including signs and symptoms, the process of evaluation, treatment, and follow-up, with attention to education and guidelines for vulvar care and hygiene.

[Lichen simplex chronicus of the anal region and its differential diagnoses. A case series]. / Lichen simplex chronicus des Analbereiches und seine Differenzialdiagnosen. Darstellung einer Fallserie.

Lichen simplex chronicus (LSC) of the anal region is characterized by massive pruritus, constant itching and a chronic course. Histology is notable for a pseudoepitheliomatous hyperplasia. Correct diagnosis as well as therapy of anal LSC sometimes is difficult. Differential diagnostic considerations include verrucous lichen planus and squamous cell carcinoma. We present three cases and then summarize pathogenesis, diagnostics, differential diagnoses and therapeutic options for lichen simplex chronicus of the anal region.

Non-neoplastic epithelial disorders of the vulva.

Lichen sclerosus, lichen planus, and lichen simplex chronicus are three of the most common non-neoplastic epithelial disorders of the vulva. Lichen sclerosus is characterized by intense vulvar itching and can affect men and women of all ages, but it manifests most commonly in postmenopausal women. Patients with lichen sclerosus have an increased risk of developing squamous cell carcinoma, and they should be monitored for malignancy. Lichen planus is an inflammatory autoimmune disorder that can affect the vulva and the vagina; it peaks in incidence between ages 30 and 60. There are three clinical variants of lichen planus affecting the vulva: erosive, papulosquamous, and hypertrophic. Lichen simplex chronicus is caused by persistent itching and scratching of the vulvar skin, which results in a thickened, leathery appearance. It is thought to be an atopic disorder in many cases and may arise in normal skin as a result of psychological stress or environmental factors. Definitive diagnosis of non-neoplastic disorders depends on the histology of biopsied tissue. All three disorders are treated with topical corticosteroid ointments of varying potency. Lichen sclerosus and lichen planus are not routinely treated with surgery, which is necessary only in patients who have a malignancy or advanced scarring that causes dyspareunia or clitoral phimosis. Educational counseling teaches patients that even though these chronic disorders cannot be cured, they can be effectively managed.

[Neurodermatitis. A risk factor for the development of squamous cell carcinoma]. / Neurodermitis. Ein Risikofaktor für die Entstehung konjunktivaler Plattenepithelkarzinome.

Squamous cell conjunctival carcinomas (SCCC) are rare. We report on a 34-year-old patient with neurodermatitis and chronic conjunctivitis who presented with a therapy-resistant corneal ulcer induced by mechanical irritation diagnosed as SCCC. Chronic blepharoconjunctivitis seems to sustain the development of SCCC in patients with neurodermatitis because of their insufficient immune response.

Lichen simplex chronicus (atopic/neurodermatitis) of the anogenital region.

Lichen simplex chronicus (LSC) of the anogenital area is an eczematous disease characterized by unremitting itching and scratching. In most instances, it arises in individuals who are genetically atopic, and as such, LSC can be viewed as a localized variant of atopic/neurodermatitis. Common triggers for the development of the disease include psychological distress, and local environmental problems such as heat, sweating, and excess dryness. Lichen simplex chronicus may also develop as a superimposed condition in the presence of other anogenital diseases such as candidiasis, psoriasis, lichen sclerosus, tinea cruris, and neoplasia. Lichen simplex chronicus frequently persists as an itch-scratch cycle, even when environmental triggers are removed and the underlying disease is treated. For this reason, successful therapy requires attention not only to trigger factors, but also to repair of the damaged barrier layer, reduction in inflammation, and breakup of the itch-scratch cycle.

Aplicación de la técnica de Schultz a un caso de neurodermatitis / Application of the Schultz technique in a neurodermatitis case

Se presenta el tratamiento de un caso con neurodermatitis congénita, de una profesional psicóloga de 30 años, quien no podía controlar su conducta de rascarse, produciéndose permanentemente escoriaciones en su piel. Se aplicó el entrenamiento autógeno de Schultz, abreviado en ocho, registrándose los valores electromiográficos, a nivel frontal, y la temperatura de ambas manos, durante la práctica del procedimiento. Los resultados del tratamiento fueron exitosos en lo inmediato, con posterioridad a dicho tratamiento y a los tres meses de seguimiento. El éxito se operacionalizó en términos de lograr controlar la conducta de rascarse y posibilitar la cicatrización de las escoriaciones

Lichen simplex chronicus.

A review of the literature for the last 20 years shows no monumental advances in the diagnosis or treatment of the disease; however, there have been some very intriguing insights into the causes. The physical and emotional aspect of the skin condition is well known but the genetic, vascular, and neurogenic implications are of interest.

Structural changes in the blood mononuclear glycocalyx has been revealed in children suffering from neurodermatitis. These shifts correlated with the cellular ability to respond to mitogenic stimulation. Treatment by UV-irradiated blood autotransfusions normalized the structure and function of mononuclears whereas routine therapy has been ineffective.

Advances in behavioral approaches to adolescent health care.

Behavior change professionals have developed treatment programs for a wide variety of health care problems affecting adolescents. Although a substantial data base of experimentally tested techniques exists for obesity, smoking prevention, and dysmenorrhea, much work remains in other areas. For example, the case studies reported on neurodermatitis and the survey work in teenage alcohol abuse must give way to systematic interventions employing group experimental designs. In addition, behavioral procedures should be compared to other treatments. Also, component analysis should be performed when multiple treatment strategies are used. Finally, strategies aimed at increasing the generalization of treatment, such as from classrooms to different community settings in substance abuse prevention programs and maintenance of treatment effects over long follow-up periods, are necessary. Only in this way will the efficacy of behavioral interventions for specific health problems be established. The leading causes of mortality among adolescents are due to accidents. Of the total number of deaths due to accidents, approximately 50% are attributed to motor vehicle accidents (National Safety Council, 1977). Many of these accidents are due to negligence, substance abuse, and, in general, immature behavior (Bakwin & Bakwin, 1972). In spite of a slow but consistent trend toward lower accidental deaths over time (National Safety Council, 1977), there still is a need for interventions designed to decrease risk-taking behavior, substance abuse, and carelessness in adolescents. Again, behavior change professionals might follow the example set by researchers who have begun to develop successful strategies for decreasing onset of cigarette smoking. These interventions and research methods, designed for use in schools, may provide a promising approach for addressing other kinds of prevention problems. It also seems appropriate to categorize cigarette smoking not only as a risk factor in the development of cardiovascular disease (Kuller, 1976), but also as a member of the risk-taking behaviors. Thus, procedures used to prevent cigarette smoking might also be adapted to prevent other kinds of risk-taking behaviors among adolescents. The work of McAlister et al. (1980), in preventing alcohol abuse as well as cigarette smoking by use of the same or similar procedures, is a case in point. Use of a procedure designed to train competency in refusing peer pressure has clear implications for reducing other risk-taking behaviors, such as reckless driving, drug abuse, and swimming and boating accidents.(ABSTRACT TRUNCATED AT 400 WORDS)
