Scalp hair folliculitis is a relatively common condition in dermatological practice and a major diagnostic and therapeutic challenge due to the lack of exact guidelines. Generally, inflammatory ...diseases of the pilosebaceous follicle of the scalp most often manifest as folliculitis. There are numerous infective agents that may cause folliculitis, including bacteria, viruses and fungi, as well as many noninfective causes. Several noninfectious diseases may present as scalp hair folliculitis, such as folliculitis decalvans capillitii, perifolliculitis capitis abscendens et suffodiens, erosive pustular dermatitis, lichen planopilaris, eosinophilic pustular folliculitis, etc. The classification of folliculitis is both confusing and controversial. There are many different forms of folliculitis and several classifications. According to the considerable variability of histologic findings, there are three groups of folliculitis: infectious folliculitis, noninfectious folliculitis and perifolliculitis. The diagnosis of folliculitis occasionally requires histologic confirmation and cannot be based solely on clinical appearance of scalp lesions. This article summarizes prominent variants of inflammatory diseases of the scalp hair follicle with differential diagnosis and appertaining histological features.
The sunlight was one of the first agents recognized to be carcinogenic for humans. There is convincing evidence from epidemiologic studies that exposure to solar radiation is the major cause of ...cutaneous melanoma in light-pigmented populations and plays a role in the increasing incidence of this malignancy. The molecular mechanisms by which UV radiation exerts its varied effects are not completely understood, however, it is considered that UVA and UVB are equally critical players in melanoma formation. Whereas UVA can indirectly damage DNA through the formation of reactive oxygen radicals, UVB can directly damage DNA causing the apoptosis of keratinocytes by forming the sunburn cells. Besides action through mutations in critical regulatory genes, UV radiation may promote cancer through indirect mechanisms, e.g. immunosuppression and dysregulation of growth factors. The carcinogenic process probably involves multiple sequential steps, some, but not all of which involve alterations in DNA structure.
We describe a case of twins with sporadic Gorlin syndrome. Both twins had common Gorlin syndrome features including calcification of the falx cerebri, multiple jaw keratocysts, and multiple basal ...cell carcinomas, but with different expressivity. One brother also had benign testicular mesothelioma. We propose this tumor type as a possible new feature of Gorlin syndrome. Gorlin syndrome is a rare autosomal dominant disorder characterized by both developmental abnormalities and cancer predisposition, with variable expression of various developmental abnormalities and different types of tumors. The syndrome is primarily caused by mutations in the Patched 1 (PTCH1) gene, although rare mutations of Patched 2 (PTCH2) or Suppressor of Fused (SUFU) genes have also been found. Neither founder mutations nor hot spot locations have been described for PTCH1 in Gorlin syndrome patients. Although de novo mutations of the PTCH1 gene occur in almost 50% of Gorlin syndrome cases, there are a few recurrent mutations. Our twin patients were carriers of a de novo mutation in the PTCH1 gene, c.3364_3365delAT (p.Met1122ValfsX22). This is, to our knowledge, the first Gorlin syndrome-causing mutation that has been reported four independent times in distant geographical locations. Therefore, we propose the location of the described mutation as a potential hot spot for mutations in PTCH1.
Olea europea, the olive tree, is an ancient tree that originates from the Mediterranean environment of Asia Minor. The edible olive fruit is also used for its oil, gained by the process of pressing, ...a nutrient with proven beneficial effects. Virgin olive oil is the natural juice of the olive fruit, which plays a major role in the healthy Mediterranean diet. The source of its health effects are the biophenols and squalenes (oleocanthal, tyrosol, hydroxytyrosol, oleuropein) it contains. They provide an exceptional antioxidative activity, removing harmful compounds from the body. Oxidants are essential in the genesis of many diseases and conditions, such as cardiovascular disorders, cancer, osteoporosis, Alzheimer disease, and premenstrual syndrome. Oleic acid, an unsaturated fatty acid, has demonstrated a significant effect in the prevention of malignant diseases such as colon cancer and breast cancer. Biophenols from olive oil successfully suppress the synthesis of LDL, a protein that is crucial in the development of cardiovascular disease, by reducing blood pressure and the development of atherosclerotic plaques. In addition, there is strong evidence of the antimicrobic effect of the biphenols from olive oil that successfully destroy colonies of microorganisms which may cause respiratory tract, intestinal, and genital tract infections.
Melanoma incidence is increasing, especially in the younger population. The aim of this study was to investigate the cost of this disease in the Croatian population and to identify costs through ...types of care and types of costs. The secondary goal was to estimate the prevalence of certain types of melanoma (as well as staging distribution) and to connect each stage and its prevalence in Croatia to related costs. A cost-of-illness analysis was performed, mainly including direct costs (monitoring, drugs, primary health care services, hospitalizations, and diagnostics). The calculations were based on data collected from Sestre milosrdnice University Hospital Center in Zagreb and from Cancer Registry Data. The number of patients with melanoma was calculated using the Markov model for melanoma staging and 5-year survival. The estimated total prevalence of melanoma in 2011 in Croatia was 2,180. The total cost of melanoma was estimated to 1,063,488 EUR, with 46% used for hospitalization and chemotherapy, 10% for dermatoscopy, and the remaining 17% being monitoring costs. The average cost per patient was estimated to range between 98 and 4,333 EUR depending on the stage of the disease. The cost of melanoma in the adult population in Croatia in a one-year timeframe accounted for as much as 0.04% of the total Croatian national health care budget for 2011. Study findings indicate the need for a clear strategy to achieve regular screening in order to detect the disease at an early stage.
Sentinel lymph node biopsy (SLNB) is an established method for the assessment of tumor aggressiveness in patients with primary cutaneous melanoma (PCM). To improve the criteria for the selection of ...SLNB candidates, the aim of our study was to determine clinico-pathohistological parameters that can serve as predictors of metastatic progression. We retrospectively evaluated all available clinico-pathohistological parameters in 844 patients with PCM diagnosed between January 1, 2005 and December 31, 2010. SLNB was conducted in 484 (57.3%) patients, 122 (14.5%) of whom had a positive node. The association between predictors and SLNB outcomes (positive SLNB and metastatic development) was tested using logistic regression analysis. The main predictors of positive SLNB were Breslow thickness (adjusted odds ratio (AOR)=1.22; 95% confidence interval (CI)=1.11-1.33), Clark levels (AOR=1.78; 95% CI=1.31-2.40), ulceration (AOR=3.1; 95% CI=1.65-5.81), microsatellitosis, gender, and tumor localization. The predictors of metastatic spread were Breslow thickness (AOR=1,69; 95% CI=1.51-1.89), Clark level (AOR=3.59; 95% CI=2.79-4.62), nodular type of melanoma (AOR=8.21; 95% CI=1.70-39.53), ulceration, mitotic rate, microsatellitosis, gender, and tumor localization. It seems that these parameters should be taken into consideration when selecting patients for SLNB since tumor thickness is not a sufficient predictor of SLNB outcome, particularly in case of very thin lesions.
Bullous pemphigoid (BP) is an autoimmune disorder which is usually chronic, with blistering that predominantly affects the skin and occasionally the mucosa, and which includes several different ...types. One of them is a very rare dyshidrosiform type which is localized on the hands and feet with small or large blisters on the palmoplantar surfaces. BP resulting from a drug reaction is a relatively rare occurrence, and so far more than 50 different medications have been identified as triggers. The aim of this article was to present the case of a paraplegic patient who developed this rare dyshidrosiform type of BP while he was being neurologically treated with baclofen. In spite of therapy with systemic and topical corticosteroids and other measures, successful treatment was achieved only after eliminating baclofen from the patient's regimen. His general state of health was seriously endangered due to nasal and skin methicillin-resistant Staphylococcus aureus (MRSA), urinary infection, and oral mycosis (soor), and he was at high risk of sepsis and a fatal outcome. Through our efforts, however, we managed to achieve an excellent outcome. According to our knowledge, this was the first case of baclofen-induced dyshidrosiform BP.
Psoriatic patients, along with skin changes, frequently show various psychological changes such as depression, anxiety and have overall lower quality of life. The aim of this study was to evaluate ...the quality of life in patients with psoriasis compared to other dermatological patients, as well as to investigate the differences between the two subgroups--type I and type II psoriasis. A total of 94 dermatological patients were included. The patients were divided into two groups, the first group made of psoriatic patients which was further divided into two subgroups, and the second, control group made of patients with other skin diseases. DSQL quality of life questionnaire was used. The study showed that among psoriatic patients there was no significant difference in the quality of life, but there was a significant difference between the psoriasis type I and the control group, which could be explained by the strong influence of the disease on the quality of life in psoriatic patients.
Abstract A collaboration of multidisciplinary experts from the European Association of Dermato‐Oncology, the European Dermatology Forum, the European Academy of Dermatology and Venereology, and the ...European Union of Medical Specialists was formed to develop European recommendations on AK diagnosis and treatment, based on current literature and expert consensus. This guideline addresses the epidemiology, diagnostics, risk stratification and treatments in immunocompetent as well as immunosuppressed patients. Actinic keratoses (AK) are potential precursors of cutaneous squamous cell carcinoma (cSCC) and display typical histopathologic and immunohistochemical features of this malignancy in an early stage. They can develop into cSSC in situ and become invasive in a low percentage of cases. AK is the most frequent neoplasia in white populations, frequently occurring within a cancerous field induced by ultraviolet radiation. Since it cannot be predicted, which lesion will progress to cSCC and when treatment is usually recommended. The diagnosis of AK and field cancerization is made by clinical examination. Dermatoscopy, confocal microscopy, optical coherence tomography or line‐field confocal‐OCT can help in the differential diagnosis of AK and other skin neoplasms. A biopsy is indicated in clinically and/or dermatoscopically suspicious and/or treatment‐refractory lesions. The choice of treatment depends on patients' and lesion characteristics. For single non‐hyperkeratotic lesions, the treatment can be started upon patient's request with destructive treatments or topical treatments. For multiple lesions, field cancerization treatment is advised with topical treatments and photodynamic therapy. Preventive measures such as sun protection, self‐examination and repeated field cancerization treatments of previously affected skin areas in high‐risk patients are advised.
Stressful life events in response to a psychosocial trigger have been reported to negatively affect the course of infections. This study was based on patients with clinical manifestations of human ...papillomavirus (HPV) infection and a control group of patients with psoriasis who were admitted over a period of one year to the Dermatology Department of Karlovac General Hospital. A total of 122 patients participated in the study, either with a confirmed diagnosis of clinical manifestations of HPV infection (n=66) or in a psoriasis control group (n=56). The aim of this study was to determine which coping strategies are used in patients with clinical manifestations of HPV infection. We used the Recent Life Changes Questionnaire and Brief COPE test for stress evaluation. There were no statically significant differences between adaptive and maladaptive coping strategies comparing patients with HPV and a control group. The difference in specific coping strategies between HPV and control groups showed that self-blame and planning strategies were statistically significantly more common in the HPV group. Patients with HPV with genital warts used maladaptive coping statistically significantly more than patients with non-genital localization of HPV. Patients with HPV who had a higher score of life stress events used maladaptive coping statistically significantly more than patients with a lower life stress events score. The results point to the need for patients with HPV with genital localization and high numbers of stress events to learn how to cope with stress, enabling them to take action and change their ways of coping. There is also a need to integrate psychological intervention into standard care protocols of dermatologic diseases.
