Religiousness, Anxiety and Depression in Patients with Glaucoma, Age-Related Macular Degeneration and Diabetic Retinopathy.

BACKGROUND: Many chronic medical conditions such as glaucoma, senile macular degeneration and diabetic retinopathy are further complicated by emotional and psychological disorders. Religiousness represents a part of a social culture and has a significant role in the prevention of mental difficulties of the patients, especially those belonging to older population. The aim of this study was to investigate the connection between religiousness, anxiety, and depression in patients with glaucoma, age-related macular degeneration and diabetic retinopathy and to test their connection related to different diagnosis. SUBJECTS AND METHODS: This cross-sectional study included 163 patients divided into three groups (glaucoma group, senile macular degeneration group and diabetic retinopathy group). Respondents voluntarily agreed to participate in the study and with assistance they fully completed the Scale of Religiousness, Hospital Anxiety and Depression Scale, General Health Questionnaire and demographic information (age, gender, education, employment and marital status). RESULTS: The results showed noticeable religiosity of the respondents (M=18.31, SD=5.28), but also the presence of anxiety (M=7.55, SD=3.73), especially in patients with glaucoma, as well as impaired mental health in AMD patients (M=19.56, SD=4.14). No differences were found in the severity of anxiety, depression, general health and religiosity between groups, but the presence of depression in subjects with age-related macular degeneration significantly affects the level of religiosity (p=0.032). CONCLUSION: These results unequivocally point to the need for further research and raising awareness of all health professionals about the importance of a holistic approach to the patient regardless of his diagnosis in order to identify the possible effective ways to deal with chronic disease considering all levels of patient's needs.

[EFFECTS OF PLATELET-RICH PLASMA IN THE TREATMENT OF CHRONIC ULCER]. / UCINCI PRIMJENE PLAZME BOGATE TROMBOCITIMA (PRP) U LIJECENJU KRONICNOG VRIJEDA.

A venous ulcer is area of discontinuity of the skin, usually localised in distal parts of the lower legs. The aetiology is associated with chronic venous disease-venous hypertension. The size and shape of venous ulcer can be different and it may even cover all circumferential of extremity. Additionally, along with basic therapy possibilities, there are many different dressings. Therefore the knowledge of each characteristic of dressing on process of epithelisation is essential as well as treating the biofilm that is responsible for complications and persistence of ulcer. One of additional therapy possibility is platelet-rich plasma.

Dermoscopy and Early Melanoma.

The lack of effective therapies for patients with advanced melanoma establishes an early recognition as the aim of clinical and dermoscopic examination, which is the most important factor for improving patient survival and decreases the treatment and management costs. Melanoma in situ is the earliest stage of melanoma. The features of early melanomas, especially in those lesions smaller than 3mm, can be very subtle clinically, dermoscopically and pathohistologically, and it is often impossible to discriminate between a melanoma and nevus. Clinically, de novo melanomas are small brown to black macula with an irregular outline. In melanomas developing in a nevus, there is an asymmetry of the lesion with marked change in color and/or shape of the pre-existing nevus. Dermoscopically, early stages of melanoma show the same global features as thicker melanomas, but in a more subtle way. Asymmetry is the most important parameter; multiple colors are rare. Significant local melanoma-specific criteria, especially when present at the periphery, are irregular pigment network, irregular streaks, and irregular dots/globules, while blue-white structures are rarely found.

Risk factors for acute respiratory tract infections in children.

Acute respiratory tract infections (ARTI) are the most common cause of childhood morbidity and an important public health problem. The aim of this study was to identify the significant risk factors for ARTI in children. The study took place in Ivankovo which is a rural area of Eastern Slavonia and with small socio-economic differences. The study population were 159 children who were 3-5 years old at the time of the study, and who were registrated at doctor's office Ivankovo. The study was conducted retrospectively through a questionnaire from January 2008 to December 2008. The risk factors studied were the gender, breastfeeding history, any atopic manifestation in the form of atopic eczema, rhinoconjuctivitis and/or asthma, the size of the family, parents smoking habits and main form of childcare. The number of ARTI requiring the consultation of a doctor throughout 2007 were measured; and whether ARTI had been treated with antibiotic or there were recommendation for symptomatic treatment only. Results of this research show that the risk factor for consulting a doctor because ofARTI in children was passive exposure to cigarette-smoke. For receiving antibiotics because of ARTI in children, the risk factors were passive exposure to cigarette-smoke and atopic manifestation. By giving the available evidence, parents must be told that ceasing smoking offers a significant opportunity to reduce the risk of ARTI in their children.

Photodynamic therapy in dermatology: current treatments and implications.

This article provides an update on photodynamic therapy by discussing each of the essential components in sequence: mechanisms of action, common photosensitizers, typical light sources, and indications. In dermatology, photodynamic therapy (PDT) is mainly used in the treatment of superficial skin cancers: actinic keratoses, Bowen's disease and superficial basal cell carcinomas. However the range of indications has been expanding continuously. PDT is also used for the treatment of other oncological indications and non-malignant conditions such as acne vulgaris and photoaged skin. The 5-aminolevulinic acid (ALA) or its methyl ester (MAL) is applied topically as photosensitizer before activation with visible light. The advantages of topical PDT are: ability to treat multiple lesions simultaneously, low invasiveness, good tolerance and excellent cosmetic results.

Dermoscopy and in vivo reflectance confocal microscopy of a congenital nevus of the nipple.

We report a 26-year-old male with a 4 mm diameter, asymmetric, irregularly pigmented and bordered, brown maculopapular lesion on the right nipple present since childhood with enlargement of the lesion within the last 3 months. Dermoscopy revealed a global globular pattern with the presence of focally light brown globules and irregular black globules in its centre. In vivo reflectance confocal microscopy (RCM) revealed dense junctional and dermal melanocytic nests of different sizes and shapes that appeared as sharply demarcated round to oval reflective structures; cellular outlines of single melanocytes were not always detected. In the centre of the lesion within the upper dermis, irregularly shaped, homogeneously reflecting structures were observed. As a clear differentiation between clusters of melanophages and melanocytic nests could not be made with certainty, an excisional biopsy was performed to establish the diagnosis of compound nevus with features of congenital nevus. Therefore, to prove that dermoscopic globules correlated with melanophages, the correlation between dermoscopic RCM and histopathology was necessary.

The role of CD4 and CD8 lymphocytes and macrophages in psoriasis vulgaris.

Current knowledge of the immunopathogenesis of psoriasis vulgaris is based on the crucial role of CD4 and CD8 lymphocytes. Also, the connection of activated lymphocytes with macrophages, especially dendritic cells and plasmacytoid dendritic cells, is considered to be significant. In the present study, the expression of CD4+ lymphocytes as well as CD8+ lymphocytes (P < 0.001) and macrophages (P < 0.001) was found to be significantly increased in lesional skin epidermis and dermis in psoriasis vulgaris patients as compared with healthy skin. These findings suggested a cascade or chain reaction with cells and cytokines playing an important role to be involved in the immunopathogenesis of psoriasis vulgaris.

Immunologic aspects of atopic dermatitis.

Atopic dermatitis/eczema is a chronically relapsing, pruritic, and inflammatory skin disease. The term "atopic eczema/dermatitis syndrome" covers the "extrinsic" and "intrinsic" atopic dermatitis. The pathogenesis of atopic dermatitis includes complex interaction between the genetic background, skin barrier defects, abnormalities in innate and adaptive immunity, abnormalities of humoral and cellular immunity, and environmental influences. Understanding the immunopathogenesis of atopic dermatitis leads to new diagnostic and therapeutic approaches. The targets in atopic dermatitis are innate immunity including improvement of skin barrier defects by supplementing lipids or inhibiting proteases, and regulating antimicrobial peptides, adaptive immunity, and induction of regulatory T cells.

Neurofibromatosis type 1 associated with dysplastic nevus syndrome.

Neurofibromatosis type 1 (NF-1) is an autosomal dominant disorder that primarily affects the development and growth of neural cell tissues. It causes tumors to grow on nerves and produces other abnormalities such as skin changes and bone deformities. Dysplastic nevus syndrome (DNS) represents multiple atypical nevi associated with polygenetic inheritance pattern and may rarely occur together with NF-1. DNS type A is a marker of increased melanoma risk, while melanoma has been rarely reported in patients with NF-1. We describe a case of NF-1 type A with DNS presenting with multiple neural tumors, cafe-au-lait spots, hamartomas in globus pallidus and pigmented melanocytic iris hamartomas (Lisch nodules). The importance of close follow up of nevi in such patients with NF-1 and DNS for the development of melanoma as well as other NF-1 associated skin disorders and with multidisciplinary approach to other associated diseases is highlighted.

Halo phenomenon with regression of acquired melanocytic nevi: a case report.

We report a case of halo-phenomenon in excisional biopsy of junctional nevi in a 19-year-old girl. The diagnosis was established histopathologically because of the lack of clinical halo and unspecific dermoscopic features. Clinicopathologic difficulties in establishing the diagnosis of these pigmented lesions, etiopathogenesis and differential diagnosis of halo nevi are emphasized. Dermatologists should be familiar with the possible changes in benign melanocytic nevi, halo reactions and possible complete regression of melanocytic nevi. Diagnostic difficulties are seen in the ultimate phase of regression when melanocytes are diminished or destroyed with immune reaction.

Keratosis follicularis spinulosa decalvans associated with acne keloidalis nuchae and tufted hair folliculitis.

Keratosis follicularis spinulosa decalvans is a rare, X-linked disorder characterized by scarring alopecia of the scalp and eyebrows in the setting of widespread keratosis pilaris. Less frequent associations are ocular abnormalities and palmoplantar keratoderma. Acne keloidalis nuchae has previously been described in one patient with keratosis follicularis spinulosa decalvans. We report another case of keratosis follicularis spinulosa decalvans with acne keloidalis nuchae and tufted hair folliculitis, thus further establishing this association.

Orthopedic and Cutaneous Reactions to Nickel after Total Hip Replacement.

Implant degradation products have shown signs of a cutaneous allergic response after implantation of a metal orthopedic replacement, loosening and failure of the joints as well as skin rashes, general fatigue, pain, and impaired wounds and bone healing. The prevalence of contact skin sensitivity in patients with a joint replacement device is higher than that in the general population. This delayed hypersensitivity to metallic orthopedic implants is more clearly defined and is a contributing factor to implant failure. Nickel was associated with hypersensitivity responses as the first cause in metallic orthopedic implants as early as 1966 by Foussereau and Laugieru and is a commonly used metal in alloys because it grants necessary strength and durability to the implant. Herein we report on delayed hypersensitivity to nickel sulfate in a patient with pain, fatigue, and contact allergic dermatitis in both inguinal regions, with instability of the left acetabular part and with five hip replacements from 1987 to 2013. The findings of this report support that primary sensitization to a metal due to an implant itself might develop. Proper investigation in patients with history or prior hypersensitivity reactions to metals and test evaluation before orthopedic device implantation is needed. before orthopedic device implantation is needed.

Treatment of vitiligo with narrow-band UVB and topical gel containing catalase and superoxide dismutase.

Narrow-band UVB has been reported to be efficacious in patients with vitiligo. The epidermis of patients with vitiligo showed reduction in the levels of catalase, in association with high levels of hydrogen peroxidase (H2O2) that is toxic for melanocytes. Based on these findings, we studied the efficacy and safety of a topical gel containing catalase and superoxide dismutase (Vitix) in combination with narrow-band UVB. The study included 22 patients of which 19 completed the 6-month study period. Patients applied the gel containing catalase and superoxide dismutase twice a day and received narrow-band UVB 3 times per week. Two different dermatologists evaluated the grade of repigmentation by photograph comparison. At the end of therapy, more than 50% of overall repigmentation was noticed in 11 of 19 (57.9%) patients. More than 75% repigmentation was recorded in three (15.79%), 26%-50% repigmentation in six (31.58%) patients and 1%-25% repigmentation in one (5.26%) patient, whereas one (5.26%) of 19 patients showed no repigmentation at all. The best response was achieved on the face and neck, with more than 50% repigmentation observed in 11 of 14 (78.6%) patients. Development of new lesions was not observed. Adverse events were mild and transient. The study showed that the combination therapy of narrow-band UVB and gel containing catalase and dismutase is a therapeutic option that could be considered in the management of vitiligo. Further evaluation of this combination in multicenter, double-blind, placebo-controlled studies should be undertaken.

Regressing seborrheic keratosis - clinically and dermoscopically mimicking a regressing melanoma.

The diagnosis of seborrheic keratosis is a clinical diagnosis. In a certain percentage of cases, differential diagnosis between seborrheic keratosis and malignant melanoma is difficult. We describe a case of regressing seborrheic keratosis simulating malignant melanoma. Clinical, dermoscopic and histopathologic examinations were performed for the occurrence of an asymmetric, irregularly demarcated, irregularly pigmented lesion measuring 1.3 x 1.5 cm on the right part of the abdomen in a 76-year-old male Caucasian. In order not to miss melanoma, the excision and histopathologic examination of the lesion with peppering is essential.

Most common inhalant allergens in atopic dermatitis, atopic dermatitis/allergic rhinitis, and atopic dermatitis/bronchial asthma patients: a five-year retrospective study.

Atopic dermatitis (AD) is a chronic relapsing inflammatory skin disease with a distinctive clinical appearance and distribution. Around 85% of patients have positive immediate skin reaction or specific IgE to different airborne allergens that are in association with respiratory allergy. The aim of this retrospective, open and uncontrolled study was to identify the most common inhalant allergens in AD patients, AD/allergic rhinitis patients, and AD/bronchial asthma patients by skin prick test per year during the 2001-2005 period.

Moisturizers.

Moisturizers combine occlusives and humectants to enhance the water-holding capacity of the skin. Further diversity in moisturizer formulation is created through the addition of special ingredients, designed to enhance the functions of the skin. These agents mimic natural ingredients. Application of moisturizers can serve as important adjunctive therapy for patients with various dermatologic disorders.

Neurofibromatosis--review of the literature and case report.

Neurofibromatoses are genetic disorders of the nervous system that primarily affect the development and growth of neural (nerve) cell tissues. These disorders cause tumors to grow on nerves, and produce other abnormalities such as skin changes and bone deformities. Although many affected persons inherit the disorder, between 30 and 50 percent of new cases arise spontaneously through mutation in the individual's genes. We report on seven cases of type 1 neurofibromatosis (NF1) diagnosed from 2001 to 2006 at our Department. There were four female and three male patients, mean age 46.1 and 49 years, respectively. All patients showed neurofibromas accompanied by fibromas, café au lait spots, cases showed five axillary freckling (lentigines) and one case showed five plexiform neurofibromas and pruritus belonging to NF1 category. All patients had affected first degree relatives. Systemic findings were rare and included optic glioma in one case and Lisch hamartoma nodules in three cases. In all cases, the diagnosis was established according to the National Institutes of Health criteria, including at least two of the diagnostic criteria for NF1 diagnosis. None of our cases had malignancies or gastrointestinal tract involvement.

Adverse reactions to food and clinical expressions of food allergy.

Adverse reactions to foods are frequent in everyday life. They are divided into toxic and immunologic food reactions. The awareness of toxic food reactions among adverse reactions to food is essential for correct diagnosis. Enzymatic food intolerance, adverse reactions to food or food additives, pharmacologic food intolerance, psychosomatic factors, food allergy with classic symptoms (anaphylaxis, urticaria-angioedema), atopic dermatitis, contact dermatitis (protein), upper and lower respiratory symptoms like rhinitis or asthma, and gastrointestinal disorders (oral allergy syndrome, colic, nausea, vomiting, diarrhea, abdominal pain) are discussed. Target organs throughout the body-ear, eye, pharynx, skin, lung, joints, and muscles-can be involved. The gold standard in diagnosis is a double-blind, placebo-controlled food challenge test. The diagnostic tools available for most food-related disorders are the skin-prick test and radioallergosorbent test. The treatment of food-induced urticaria consists of elimination of the offending food or substance from the diet, use of antihistamines, and immunotherapy.

Contact allergy and sociodemographic characteristics.

The aim of the study was to determine the frequency of positive patch test reaction to different contact allergens according to patients age, sex, occupation and clinical features. Between 1999 and 2003, patch testing was performed in 3,293 patients with respective clinical diagnoses. Patch testing was done by the standard technique proposed by the International Contact Dermatitis Research Group (ICDRG). Study results showed statistically significant differences in patch test response according to sex and age for three allergens (cobalt chloride, nickel sulphate and thiomersal); according to occupation for nine allergens (cobalt chloride, nickel sulphate, balsam of Peru, fragrance mix, thiuram mix, wood tars, neomycin sulphate, thiomersal and detergents), and clinical diagnosis for two allergens (nickel sulphate, and wood tars). The most common and relevant allergens were: nickel sulphate, cobalt chloride and carba mix. They were found in all examinees regardless of age, sex, occupation and diagnoses. The increased awareness of allergens and their potential sources may help to limit the usage of these chemicals in manufacture of consumer products.

Drug-Induced Rosacea-like Dermatitis.

Rosacea is a common, chronic cutaneous disorder with a prevalence of 0.5-10%, predominantly affecting women. The disease presents with a heterogeneous clinical picture characterized by transient flushing, persistent facial redness, telangiectasias, and, in more severe clinical forms, the presence of inflammatory papules and pustules in the central third of the face. Although its pathophysiology is complex and still remains unknown, factors that exacerbate the disease are well defined. They include genetic predisposition as well as external factors such as exposure to UV light, high temperature, and diet. Besides these well-known factors, recent studies suggest that drugs and vitamins could also be possible factors inducing rosacea-like dermatitis or aggravating pre-existing rosacea. Although these are less common possible triggering factors, the aim of this article is to present the current knowledge on the association between use of certain drugs or vitamins and rosacea.
