    ABSTRACT: To evaluate the role of oxidative stress in the pathogenesis of vitiligo and the effect of narrowband (NB) ultraviolet (UV) B phototherapy on oxidative stress markers. Patients with vitiligo and healthy control subjects were included in the study. Patients in the vitiligo group were treated with an NB-UVB regimen (3 × weekly for 6 months). Erythrocyte superoxide dismutase activity (SOD), erythrocyte malonyldialdehyde (MDA) and erythrocyte glutathione peroxidase activity (GSH-Px) levels were assessed in all participants at baseline, and after NB-UVB phototherapy in patients with vitiligo. A total of 24 patients with vitiligo and 27 control subjects were included in the study. Before treatment, erythrocyte MDA levels were significantly higher, and SOD and GSH-Px levels were significantly lower, in patients with vitiligo compared with controls. NB-UVB phototherapy was associated with a significant reduction in MDA levels and a significant increase in GSH-Px levels, compared with baseline, in patients with vitiligo. NB-UVB phototherapy may relieve oxidative stress in patients with vitiligo by reversing the oxidant-antioxidant imbalance that is considered to play a role in the pathogenesis of this disease.

    ABSTRACT: To assess clinical and laboratory parameters associated with metabolic syndrome in Turkish patients with moderate or severe plaque-type psoriasis and nonpsoriatic controls. Patients with moderate or severe plaque psoriasis (patient group) or with nonpsoriatic dermatological disease (controls) were included. Waist circumference, weight, height and arterial blood pressure were measured, together with fasting blood glucose, triglyceride, high density lipoprotein (HDL), fibrinogen, homocysteine and adiponectin levels. Metabolic syndrome was diagnosed using National Cholesterol Education Program-Adult Treatment Panel III criteria. Out of 90 patients (50 with psoriasis; 40 controls), metabolic syndrome was more frequent in the patient group than in controls. In terms of metabolic syndrome parameters, only hypertension was more frequent in patients with psoriasis compared with controls. There was no statistically significant difference between the patient and control groups for obesity, hypertriglyceridaemia, HDL levels or hyperglycaemia. Fibrinogen levels were increased and adiponectin levels were decreased in the psoriasis group. No between-group difference in homocysteine levels was found. In this small study, metabolic syndrome was found to be more frequently identified in Turkish patients with psoriasis than in controls; metabolic syndrome could lead to increased cardiovascular disease risk in patients with moderate to severe psoriasis.

    ABSTRACT: The serotonin (5-hydroxytryptamine; 5-HT) is a key neurotransmitter in the central nervous system and a responsible mediator for the itch. Dysregulation of serotonergic pathways has been implicated in the pathogenesis of many complex neuropsychiatric diseases. The purpose of this study was to evaluate the relationship between lichen simplex chronicus and dysfunction and serotonin transporter (5-HTT) gene polymorphism. Thirty-nine patients with lichen simplex chronicus and 61 healthy control subjects were examined. The results for the patients and control subjects were not significantly different (P > 0.05) in long/long (L/L) and long/short (L/S) genotypes of 5-HTT gene-linked polymorphic region (HTTLPR) polymorphism, but short/short S/S genotype was lower in lichen simplex chronicus patients (17.9%) than in controls (42.6%). This difference was statistically significant (P = 0.028). The results for the patients and control subjects were not significantly different in 12/12, 10/12 and 10/10 genotypes of variable number of tandem repeat (VNTR) polymorphism (P > 0.05). Beck depression inventory (BDI) scores and symptom checklist-90-revised (SCL-90) psychotic subscale were overrepresented significantly in the 12/12 genotypes than 10/12 genotypes. State and Trait Anxiety Inventory tests (STAI-I and -II) point averages were not statistically significant (P > 0.05) S/S genotypes of HTTLPR polymorphism in the 5-HTT gene may be related to lichen simplex chronicus and that patients who have 12/12 genotypes of VNTR polymorphism may be affected psychiatrically.

    ABSTRACT: The case of a 14-year-old girl suffering from Klippel-Trenaunay syndrome associated with multiple port-wine stain type vascular anomalies and varicose veins involving upper limbs is described. Finger deformations are common in Klippel-Trenaunay syndrome. In our patient, striking hypertrophy of soft tissues and overgrowth of bones were observed on both forearms and finger deformations were observed particularly on right thumb and index finger. Although lower limb involvement is very common amongst the patients with Klippel-Trenaunay syndrome, in our patient involvement of the lower limbs was not observed.

    ABSTRACT: Flutamide is an effective drug in treatment of hirsutism. Hepatotoxicity occasionally may occur with therapeutic doses (750-1500 mg/day), 3 months after initiation of treatment. Monitoring of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels is recommended to obviate serious hepatotoxicity. Two hundred and fourteen patients with mean age of 20.9+/-2.34 years suffering from hirsutism were included in the study. Of these 214 women, 117 had diagnosis of polycystic ovarian syndrome (PCOS), and 97 had diagnosis of idiopathic hirsutism. Thirty age-matched (mean age 20.3+/-2.0 years) normal women without signs of hirsutism and with normal menstrual cycle served as control group. Hirsutism was assessed using modified Ferriman-Gallwey method at the beginning and at the end of the treatment. Serum levels of luteinizing hormone (LH), follicle stimulant hormone (FSH), prolactin (PRL), estradiol (E2), androstenodion (A), testosterone (T), dehydrotestosterone (DHT), dehydroepiandrosterone sulfate (DHEAS), dehydroepiandrosterone (DHEA), 17-hydroxyprogesterone (17-P), sex hormone binding protein (SHBG), and ACTH were measured. Pelvic ultrasonography was performed for diagnosis of PCOS. Fifty-seven patients with PCOS (group 1) were given flutamide 125 mg/day + oral contraceptive. Sixty patients with PCOS (group 2) were given flutamide 250 mg/day + oral contraceptive. Forty-seven patients with IH (group 3) were given flutamide 125 mg/day alone, and 50 patients with IH (group 4) were given flutamide 250 mg alone. Thirty women in control group (group 5) were given placebo only. ALT and AST levels were measured in the beginning of the treatment, and repeated after 3, 6, 9 and 12 months. No incidence of increase in AST or ALT levels (>or= 45 U/L) was observed in any of the groups. No evidence of hepatotoxicity in any of the 214 hyperandrogenic women was observed on low-dose flutamide for 1 year. We conclude that flutamide in a dosage of 125 or 250 mg daily is a safe drug in the long-term treatment of hirsutism. The follow-up of patients receiving flutamide can be done by monitoring AST or ALT levels for hepatotoxicity.

    ABSTRACT: The present study aimed to evaluate the effectiveness of 2.5 mg/kg/day cyclosporin (CsA) treatment in patients with severe chronic idiopathic urticaria (CIU) and the impact of CsA treatment on several cytokines involved in the etiopathogenesis of CIU. Twenty-seven CIU patients and 24 healthy control subjects were included in the study. The autologous serum skin test (ASST) for autoantibodies and urticaria activity scoring (UAS) were measured for the evaluation of the clinical severity and the response to therapy, and the serum levels of interleukin (IL)-6, IL-8, IL-2 receptor, IL-1beta, tumor necrosis factor (TNF)-alpha and IL-5 were measured. The mean UAS score was 32.07 +/- 7.05 and 6.22 +/- 3.84 before and after CsA treatment, respectively. The serum IL-2 receptor, TNF-alpha and IL-5 levels of patients before CsA treatment were statistically higher than those of the control group (P = 0.001), and after 4 weeks of CsA therapy the mean IL-2R, TNF-alpha and IL-5 levels were significantly decreased. The data from this study demonstrate that CsA therapy is efficient and safe for CIU patients. Increase in clinical efficacy and marked decreases in serum cytokine levels suggest that inhibition of cytokine generation is involved in the action of the drug in this clinical setting.

    ABSTRACT: Chronic urticaria is defined as the daily or almost daily occurrence of weals for more than 6 weeks. The underlying pathophysiology is reported to be mast cell activation, with release of mast cell mediators, predominantly histamine. Substance P is a neuropeptide and has the capacity to provoke histamine release from skin mast cells. Angiotensin-converting enzyme (ACE), widely expressed in skin, is one of the major peptidase for the degradation of substance P. An insertion/deletion polymorphism (I/D) in the ACE gene has been reported to be related to the levels of enzyme. An increase in substance P levels due to a polymorphism in ACE gene might be related to the pathology. Thus, we aimed to investigate whether there is an association between ACE I/D polymorphism and chronic ordinary urticaria. Ninety-five patients with chronic ordinary urticaria were recruited and divided into two groups according to autologous serum skin test status and accompanying angio-oedema. One hundred and sixty-one healthy subjects were enrolled as control group. All participants were genotyped for I/D polymorphism in intron 16 of the ACE gene by polymerase chain reaction. A statistically significant association was not found between ACE I/D polymorphism and chronic ordinary urticaria. Further analyses of chronic ordinary urticaria patients showed that ACE I/D polymorphism was not associated with autologous serum skin test status of patients. However, the frequencies of II genotype and I allele were statistically significantly higher in chronic ordinary urticaria patients with accompanying angio-oedema with regard to angio-oedema-negative patients (II genotype: 24% vs. 9%, P = 0.0002; I allele: 58% vs. 27%, P = 0.0001) and control group (II genotype: 24% vs. 19%, P = 0.01; I allele: 58% vs. 41%, P = 0.03). The results of this study suggest no evidence of an association between ACE I/D polymorphism and risk of developing chronic ordinary urticaria. However, it can be a contributing factor to susceptibility of angio-oedema in chronic ordinary urticaria.

    ABSTRACT: This study aimed to detect metastases in patients with stage III or IV cutaneous melanoma by (18)F-fluorodeoxyglucose positron emission tomography combined with computed tomography (FDG-PET/CT). Thirty-nine patients with clinically evident stage III or IV melanoma underwent whole-body FDG-PET/CT scans for metastatic disease and these results were compared with those of biopsy. Scans for 38 of the patients were evaluated; one patient's scan could not be evaluated. There were 11 true-positive, two false-positive, 24 true-negative and one false-negative scans for the detection of melanoma metastases, with sensitivity 91%, specificity 92%, accuracy 92%, and positive and negative predictive values 84% and 96%, respectively. False-positive FDG-PET/CT scans were due to sarcoidosis in the lung and infected cyst in the liver. It is concluded that FDG-PET/CT scanning has high sensitivity and specificity for detecting stage III or IV metastatic melanoma.

    ABSTRACT: Anastrozole is a third-generation nonsteroidal aromatase inhibitor which is used in the treatment of breast cancers. Anastrozole has also been used in the treatment of dermatomyositis skin eruptions but its direct effects on skin have not been well documented. To study the effects of anastrozole administration on neonatal rat skin. Forty Sprague-Dawley female newborn rats were separated into two control groups and two experimental groups (n = 10). One day after birth the control group of newborn rats were given daily 0.02 ml saline subcutaneously for a period of 15 days. The first experimental group of rats were treated with 0.05 mg/100g/day anastrozole subcutaneously for 15 days whereas the second experimental group of rats were given 0.25 mg/100g/day anastrozole subcutaneously for 15 days. Histopathological assessments were made and compared with the control groups. Increased keratinization, strippling, hypertrophic epidermal cells and disorganization of the epidermal cells were observed in the first experimental group. In the second experimental group in addition to these pathologic findings acantholysis was observed. The administration of anastrazole in newborn rats showed considerable harmful effects.

    ABSTRACT: Brucellosis remains an important public health problem in Turkey, just as it is in other regions of the world. This study was conducted to determine the types and rates of cutaneous lesions that occur in patients with brucellosis. Brucellosis was diagnosed by standard tube agglutination testing for Brucella antibodies at a titer of 1/160 or higher in the presence of compatible clinical findings. A total of 140 patients who had been given a diagnosis of brucellosis were prospectively observed in the dermatology clinic. Of these patients, 102 (72.9%) were female, with a mean age of 44.11+/-18.22 y, and 38 (27.1%) were male, with a mean age of 46.44+/-14.58 y. The duration of symptoms was less than 2 mo (acute) in 75 patients (53.5%), from 2 to 12 mo (subacute) in 30 patients (21.4%), and longer than 12 mo (chronic) in 35 patients (25.0%). Cutaneous findings related to brucellosis were observed in 8 (5.71%) of the 140 cases. Maculopapular eruptions were observed in 2 patients (25%), erythema nodosum-like lesions in 2 (25%), psoriasiform lesions in 1 (12.5%), palmar erythema in 1 (12.5%), malar eruption in 1 (12.5%), and palmar eczema in 1 (12.5%). The investigators concluded that although cutaneous findings encountered in brucellosis are generally not specific to this disease, the presence of these findings may be useful in diagnosing brucellosis in persons who live in, or used to live in, endemic regions.

    ABSTRACT: The role of psychological factors in the pathogenesis of alopecia areata (AA) has long been the subject of debate. Numerous studies have provided controversial results. This case-control study was undertaken to determine the significance of stressful life events and other psychological factors in the etiopathogenesis of AA. The impact of the disease on the quality of life was also assessed. Fifty-two adult patients (18 females and 34 males) diagnosed with AA and 52 age- and sex-matched individuals selected from hospital staff without any hair loss (control group) were evaluated using the major life events scale, Beck depression and Beck anxiety inventories, and the Short Form-36 health survey (SF-36). In addition, comparison was performed between two patient groups created according to whether or not they linked emotional trauma with their AA attack. There was no statistically significant difference between the patient and control groups with regard to the total scores of stressful major life events, depression, and anxiety. Of the eight subscales on SF-36, vitality and mental health scores were higher in the control group, whereas social functioning scores were higher in the patients. The total number of stressful life events was higher in patients who attributed their disease to a stressful life event than in those who did not. It appears unlikely that anxiety and depression play a major role in the etiopathogenesis of AA, but stressful life events may act as a trigger in the onset and/or exacerbation of the disease. Furthermore, AA seems to have a partly negative impact on the health-related quality of life.

    ABSTRACT: Hydatid disease caused by Echinococcus often manifests as slowly growing cystic mass and mainly affects the liver or lung and rarely other parts of the body such as brain, heart, bone and muscle. Cyst may be single or multiple, uni-or multiloculated. In this paper 4 hydatic cases, multiple and atypically localized are presented. Of the 4 cases, 2 were known to suffer from hydatid disease, having had a hepatic cyst removal previously. Thus, when faced with a hydatid cyst in any part of the body, it is preferable to examine other parts of the body by radiological imaging methods.

    ABSTRACT: Treatment of atrophic acne scars is difficult and generally unsatisfactory. Although many clinical studies have been performed to investigate the efficacy of glycolic acid in the treatment of acne vulgaris, to the best of our knowledge no placebo-controlled study has been carried out to ascertain the effect of glycolic acid on atrophic postacne scars. A single, blind, placebo-controlled, randomized comparative clinical study was conducted in 58 women with atrophic acne scars. The subjects were randomly divided into three study groups. Glycolic acid peels with 20%, 35%, 50%, and 70% concentrations were applied serially at 2-week intervals to 23 patients in Group A. Twenty patients in Group B used a 15% glycolic acid cream once or twice daily for a period of 24 weeks. The remaining 15 patients in Group C applied a placebo cream twice daily during the same period. The differences between the results in the different groups were statistically significant at week 24 (P<0.001). Home application of low-strength glycolic acid was better tolerated and had less side-effects than glycolic acid peels; however, repeated short-contact 70% glycolic acid peels provided superior results compared with the maintenance regimen (P<0.05), and apparently good responses were observed only in the peel group (P<0.01). Glycolic acid peeling is an effective modality for the treatment of atrophic acne scars, but repetitive peels (at least six times) with 70% concentration are necessary to obtain evident improvement. Long-term daily use of low-strength products may also have some useful effects on scars and may be recommended for patients who cannot tolerate the peeling procedure.

    ABSTRACT: Cutis tricolor is a recently described skin disorder characterized by the coexistence of congenital hyper- and hypopigmented macules adjacent to each other on a background of normal skin. It has been considered to represent an example of didymosis (twin spotting), which is a particular form of loss of heterozygosity. Cutis tricolor may occur as a cutaneous feature of various multisystem birth defects. We report two sisters with cutis tricolor. One of them had, in addition, unilateral hypoplasia of the breast. This familial occurrence of cutis tricolor may best be explained by the concept of paradominant inheritance. 2003.
