RESUMO

Keratosis pilaris (KP) is a benign cutaneous disorder characterized by folliculocentric hyperkeratotic papules most often occurring on the proximal extremities. Erythema is usually limited to perifollicular skin, but when keratosis pilaris presents on a background of confluent erythema, the term keratosis pilaris rubra (KPR) is used. The histological findings associated with KP have not been well described in the literature. Herein, we present a case of a 14-year-old male with a 7-year history of erythema and follicular-based papules over his bilateral cheeks, consistent with KPR. Histological examination revealed abundant mucin, keratotic follicular plugging, and periadnexal lymphocytosis. Our novel finding of abundant dermal mucin expands the histopathologic description of KPR.

RESUMO

Keratosis pilaris (KP) is a common skin finding that presents as follicular hyperkeratotic papules on the proximal extremities in patients with a propensity for atopy. Although often asymptomatic, the stippled appearance is cosmetically disturbing to patients and difficult to treat as current therapies are limited in availability and efficacy. Nitric oxide (NO) has been found to be essential in basic systemic and cutaneous physiologic function, specifically in terms of its anti-microbial and anti-inflammatory properties, which evolutionarily was maintained by ammonia-oxidizing bacteria (AOB). As modern hygiene practices have improved, there has been a gradual loss of cutaneous AOB and, therefore, the availability of an important source of human physiologic NO. We propose that restoring this dermal microflora with a purified strain of AOB, Nitrosomonas eutropha (D23), may reduce the overall cutaneous inflammatory state and, thus, be a potential therapeutic option for improving the cosmetic appearance of a skin condition such as KP which is often found in association with xerosis and atopic dermatitis.

RESUMO

BACKGROUND: Human papillomaviruses (HPVs) of the beta genus (beta-PV), especially HPV5 and HPV36, are proposed to play a pathogenic role in psoriasis, but many previous studies have failed to control for potential confounders, including treatment. OBJECTIVES: To re-examine the relationship between beta-PV and psoriasis addressing limitations present in previous studies and analyse intra-patient concordance for carriage of HPV. METHODS: Plucked eyebrow hairs and forearm skin scrapes were collected from 20 newly diagnosed, previously untreated adult patients with psoriasis and 23 normal controls. A combination of type-specific and degenerate polymerase chain reaction methods was used to achieve comprehensive HPV DNA detection. RESULTS: The prevalence of HPV in hair and skin from psoriasis patients was higher than in controls (83.3% vs. 46.7%, respectively, P < 0.03 corrected for age and clustering). HPV5 or HPV36 were not over-represented. The profile of diverse beta-PV types was comparable in the two groups. Intra-patient concordance for HPV DNA at separate sites was high (P < 0.00001). CONCLUSIONS: Our data do not support a specific causal role for HPV5 or HPV36 in psoriasis, but suggest that psoriatic skin may be more permissive for viral presence than normal skin. High intra-patient concordance for specific HPV types at separate sites, together with the ubiquity of HPV DNA in normal human skin, suggests that an individual becomes colonized with a particular beta-PV profile presumably to the exclusion of other types. To what extent this HPV profile is then causal in the subsequent development of hyperproliferative skin disease is unknown.

RESUMO

Organ representation areas of different internal organs were localized on the eyebrows for the first time in 2005 and localized on the surrounding tissue around the eye in 2008 using the Bi-Digital O-Ring Test (BDORT) electromagnetic resonance phenomenon between 2 identical tissue. The appearance of white hairs at specific organ representation areas of eyebrows represent an abnormal condition of the specific internal organ if the BDORT grading is (-)4 or a higher negative value. When one of these white hairs on the eyebrows is examined at any location along its entire length by the BDORT, if the grading is a very abnormal negative value of (-)6 or a higher (-) value, significantly abnormal conditions exist or existed at the corresponding time at the specific location of the hair. The heart representation area on the eyebrow is located nearest to the bridge of the nose on each side, where abnormally increased BNP (Brain Natriuretic Peptide) and cardiac Troponin I content is detected on the part of the white hair where the BDORT grading is (-)6 or a higher negative value. In the very abnormal part of the white hair representing the heart, Asbestos, TXB2, and PLGF (Placental Growth Factor) are markedly increased, while DHEA is markedly reduced. If Integrin alpha5beta1 and Oncogene C-fos Ab2 are more than 5-10 ng (BDORT units), malignancy can be suspected. When one optimal dose of DHEA, 8.5 mg, was taken once, normal body tissue telomere was increased from less than 1 ng (during which time the patient experienced extreme tiredness and frequent urination), to 525 ng (BDORT units), not only did severe tiredness & frequent urination completely disappear, but also the white hair representing the left ventricle changed to black hair, and the semi-transparent white hair representing the kidney changed to a non-transparent white hair, with significant decreases in the abnormal parameters. Thus, it is possible to detect unrecognized serious heart conditions or early-stage cancer that are currently present or that were present in the recent past by examining the white hairs of the eyebrows, and these diseases can be improved by one optimal dose of DHEA or Astragalus.

RESUMO

Epidermodysplasia-verruciformis-associated human papillomavirus DNA has been demonstrated in squamous cell carcinomas and plucked hair from immunocompetent patients and renal transplant recipients. This study investigated the association between infection with epidermodysplasia-verruciformis-associated human papillomavirus, identified by the detection of viral DNA in plucked eyebrow hairs, and solar keratoses. These lesions are strongly predictive of squamous cell carcinoma. In a cross-sectional study 518 individuals were enrolled from a randomly selected sample of a subtropical Australian community. Epidermodysplasia-verruciformis-associated human papillomavirus DNA in eyebrow hair was detected using a nested polymerase chain reaction specific for epidermodysplasia-verruciformis-associated human papillomavirus types. Epidermo dysplasia-verruciformis-associated human papillomavirus DNA was present in 121 (49%) of 245 men and 116 (44%) of 262 women. There was a strongly significant increase in epidermodysplasia-verruciformis-associated human papillomavirus infection with age (p < 0.00001), with prevalences of 29% in the 25-39 y age group, 42% at 40-59 y and 65% in the 60-79 y age group. Among men there was a strong association between epidermodysplasia-verruciformis-associated human papillomavirus and solar keratoses with an odds ratio, adjusted for age, skin color, and occupational sun exposure, of 3.40 (95% confidence interval, 1.77-6.53). No such association was found among women [odds ratio 1.03 (95% confidence interval 0.59-1.77, after adjustment for the same factors)]. Differences in occupational sun exposure and smoking histories could not explain these apparently different associations between epidermodysplasia-verruciformis-associated human papillomavirus infection and solar keratoses in men and women. In conclusion, epidermodysplasia-verruciformis-associated human papillomavirus infection is associated with solar keratoses in men suggesting that epidermodysplasia-verruciformis-associated human papillomavirus infection, in conjunction with sex specific factors (like androgens), may be involved in neoplastic changes of keratinocytes.
