RESUMO

BACKGROUND: Narrowband ultraviolet B (NB-UVB) phototherapy has become a widely used, standard treatment modality in dermatology. The effect of 8-methoxypsoralen plus ultraviolet A on antinuclear antibody (ANA) formation has been investigated extensively, but there are very scarce data about the potential risk of NB-UVB phototherapy inducing production of ANAs. The aims of this study were evaluation of ANA status before and after NB-UVB treatment and comparison of ANA status with the healthy control group. METHODS: Phototherapy unit database was used to identify patients who had received whole body NB-UVB treatment. Analyses of ANA were performed twice in the study group that were before initiation of the NB-UVB phototherapy and after cessation of the therapy. Also, ANAs were screened in the control group. RESULTS: A total of 95 patients (50 males and 45 females; mean age: 43.03 ± 13.40) treated with NB-UVB radiation and 90 age- and sex-matched controls were included in the study. Thirteen patients (13.7%) were found to develop ANAs at the end of the treatment. ANA positivity was significantly more common in patients after phototherapy than in patients before phototherapy and than in the control group. None of the patients in the positive ANA group was diagnosed with any connective tissue diseases. CONCLUSION: This study revealed that ANA positivity increased after NB-UVB phototherapy. However, it did not provide evidence for increased connective tissue disease risk. Therefore, ANA might not need to be routinely checked before treatment unless the patients have signs and symptoms indicating autoimmune diseases.

RESUMO

Amyloidosis cutis dyschromica (ACD) is a rare form of primary cutaneous amyloidosis. ACD, first described by Morishima in 1970 is characterized by (i) macular, speckled, reticular hyperpigmentation with hypopigmented spots distributed extensively over the body; (ii) little or no pruritus; (iii) prepubertal onset; and (iv) focal subepidermal amyloid deposition. A 49-year-old woman presented with a 20-year history of progressive, asymptomatic, generalized mottled hyper- and hypopigmented macules all over the body. Histopathological examination of a punch biopsy specimen showed deposition of homogeneous, eosinophilic material in the papillary dermis. This amorphous, eosinophilic material was stained metachromatically with crystal violet stain and found to be compatible with amyloid. Based on the clinical and histopathological findings, the patient was diagnosed as having ACD. Amyloidosis cutis dyschromica must be considered in the differential diagnosis of patients with diffuse dyschromatosis including both hyperpigmented and hypopigmented lesions and histopathological confirmation is necessary in order to reach a correct diagnosis.

RESUMO

BACKGROUND: Endocan is a novel human endothelial cell-specific molecule. The central role of leukocytes and endothelial dysfunction in the development of Behçet disease (BD) led us to hypothesize that endocan might be a marker of this disease. OBJECTIVE: We investigated the relationship between serum levels of endocan and disease activity in patients with BD. METHODS: In all, 33 patients (16 active, 17 inactive) with BD and 35 healthy persons were included in the study. Endocan and C-reactive protein were measured in all subjects. RESULTS: Patients with BD had significantly higher serum endocan levels. Mean serum levels of endocan were 1.29 ± 0.60 ng/mL (range: 0.58-2.99) in patients with BD and 0.75 ± 0.16 ng/mL (range: 0.48-1.21) in control subjects (P < .001). In patients with BD, serum endocan levels correlated moderately but significantly with C-reactive protein, erythrocyte sedimentation rate, and disease activity. Receiver operating characteristic curve analysis suggested that the optimum endocan level cut-off point for patients with BD was 0.87 ng/mL, with a sensitivity and specificity of 75.8% and 80%, respectively (area under curve 0.835, 95% confidence interval 0.738-0.932). LIMITATIONS: The main limitation of our study is the relatively small sample size. CONCLUSIONS: Circulating endocan may be a marker of BD activity.

RESUMO

OBJECTIVES: Regardless of methicillin resistance, Panton-Valentine leucocidin (PVL)-positive Staphylococcus aureus isolates are associated with various types of infections and outbreaks. Limited data exist about the PVL content of S. aureus strains in Turkey. In this multicentre study, we aimed to assess the PVL positivity and antimicrobial susceptibilities of S. aureus isolates recovered from skin and soft tissue samples of both community and nosocomial origin in the study period, 2007-08. METHODS: Two hundred and forty-two [92 community-acquired (CA) and 150 hospital-acquired (HA)] isolates were included in the study. Analysis of mecA and PVL was carried out using PCR. All isolates underwent susceptibility testing according to the CLSI. RESULTS: Out of 242 isolates, 77 were mecA positive. PVL was not found among methicillin-resistant S. aureus (MRSA) isolates, but 8 (5.3%) HA methicillin-susceptible S. aureus (MSSA) and 14 (15.2%) CA-MSSA, mostly isolated from furuncles (71.4%), were positive for PVL. Among PVL-positive strains, the penicillin resistance rate was 90.9%. Low resistance rates, <10%, were detected for erythromycin, fusidic acid and co-trimoxazole. PVL-positive strains showed higher rates of susceptibility to erythromycin, gentamicin and rifampicin than negative isolates. CONCLUSIONS: Based on the findings of this study, infection related to PVL-carrying CA-MRSA is not at an alarmingly high level, but population-based surveillance studies should be done to determine the real status.

RESUMO

BACKGROUND: Our aim was to document the frequency of gastrointestinal (GI) involvement of Behçet's disease (BD) at endoscopic examination. Also, we aimed to analyze whether GI lesions were correlated with other systemic components of BD. METHODS: Fifty patients with BD were enrolled in the study. Patients in whom optimal colonoscopic examination of both the colon and terminal ileum could be performed were included. An ileum biopsy was taken from all cases. Upper GI endoscopy findings, presence of genital ulcers, uveitis, dermatological lesions, pathergy test, neurological involvement and peripheral vasculitis, and laboratory findings were recorded. Thirty age- and sex-matched persons who had perfect bowel cleansing and had a macroscopically normal colon and terminal ileum at colonoscopy without any systemic diseases were enrolled as the control group. RESULTS: Nine patients and 1 case had macroscopic ileum and colon lesions, respectively. Microscopic examination of BD patients with normal colon and terminal ileum at colonoscopy revealed 61% abnormal ileum histologies. That ratio was 30% for the control group (p < 0.001). None of the patients had any lesions suggesting BD at upper GI endoscopy. There was no correlation between macro- or microscopic GI involvement and other components of BD. CONCLUSIONS: Lower GI tract, especially ileum involvement, is frequent in BD. Most of the patients have inflammation in the ileum even in the absence of macroscopic lesions.

RESUMO

Narrow-band ultraviolet B (NB-UVB) phototherapy is an effective and widely used treatment modality for psoriasis and other inflammatory skin diseases. The carcinogenic effect of PUVA treatment has been investigated extensively, but there is very scarce data about the role of NB-UVB in the development of skin cancer. The aim of this study was to investigate the potential carcinogenic risk of NB-UVB therapy in various skin disorders. In this cross-sectional study, we evaluated 100 patients who had received whole-body NB-UVB treatment and 100 age- and sex-matched controls. Phototherapy unit database was used to identify patients. A total of 100 patients (53 males and 47 females) treated with NB-UVB and 100 controls were included in the study. The patient group revealed no cases of melanoma or non-melanoma skin cancer, while ten of them were found to have solar lentigines. Basal cell carcinoma in a patient and nine patients with solar lentigines were detected in the control group. There was no statistically significant difference between patient and control groups in terms of skin cancer and solar lentigines. This study does not provide evidence for an increased skin cancer risk in patients treated with NB-UVB phototherapy. However, we have detected the occurence of 10 cases of solar lentigines. Still, definitive prospective longitudinal studies with a greater number of patients and prolonged follow-up are required to specifically address skin cancer risk in relation to NB-UVB phototherapy.

RESUMO

The objective of our study was to elucidate serum levels of atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), and C-type natriuretic peptide (CNP) in Behcet's disease (BD) patients with active and inactive period. The multicenter study included 53 patients with active (n = 28) and inactive (n = 25) BD (mean age, 34.3 +/- 9 years; 15 men and 38 women) satisfying the International Study Group criteria and 26 healthy controls (mean age, 34.4 +/- 6.1 years; seven men and 19 women) matched for age and gender from a similar ethnic background. Serum natriuretic peptides levels were determined by enzyme immunoassay kit. Mean serum ANP concentrations in the active patients (4.01 +/- 1.21 ng/ml) were significantly lower than in the healthy controls (5.76 +/- 1.99 ng/ml, p = 0.004). Mean serum BNP levels were found to be significantly higher in both the active (6.19 +/- 2.97 ng/ml) and inactive (6.49 +/- 2.88 ng/ml) BD groups compared with the control group (3.82 +/- 1.1 ng/ml, p = 0.004 and p = 0.001, respectively). Mean serum CNP concentrations in the active patients (0.49 +/- 0.12 ng/ml) were significantly lower than in the inactive patients (0.65 +/- 0.2 ng/ml, p = 0.017) and the healthy controls (0.8 +/- 0.27 ng/ml, p < 0.001). Our results suggest that changes in natriuretic peptide levels may be associated with vasculitis that play role in the etiopathogenesis of the BD.

RESUMO

Psoriasis is a common inflammatory and hyperproliferative skin disease characterized by hyperproliferation of keratinocytes. The pathogenesis of psoriasis has yet to be determined. The control of cell growth is a delicately balanced process, regulated by external signals or the internal genetic program of an individual cell. In psoriasis, these processes are disturbed and some candidate genes like p53 are suspected of being involved in the pathogenesis of the disease. The p53 protein is essential for the regulation of cell proliferation. The study was performed on 32 patients with psoriasis (24 plaque type, eight guttate type). Biopsy specimens for immunohistochemical determination of p53 protein expression were collected from both the lesional and the nonlesional skin sites that were not exposed to sun in all of the patients (n = 32). Taking the ultraviolet (UV) exposure of the skin into consideration, a third skin sample was taken from each patient (n = 7) who had lesions on the sun-exposed areas. Immunohistochemical assessment of p53 expression in skin was determined as p53 protein expression per 1000 cells (keratinocytes). The statistical analysis revealed that the expressions of p53 per 1000 cells were higher in non-sun-exposed lesional skin than the non-sun-exposed nonlesional skin, also in plaque-type psoriasis than guttate-type psoriasis (P = 0.000, P = 0.046, P = 0.037, respectively). There was a positive correlation between the p53 expression in non-sun-exposed lesional skin versus expression in sun-exposed lesional skin (cubic centimeters = 0.811, P = 0.027). Our results show a stronger association of elevated p53 expression with chronic rather than acute inflammatory psoriasis. This may indicate a mechanistic difference between plaque-type and guttate psoriasis. Alternatively, this could reflect a chronological course as the disease transitions from an acute to a chronic phase.

RESUMO

Paraneoplastic acrokeratosis of Bazex (PAB) or Bazex's syndrome is a rare, paraneoplastic syndrome that mostly affects men over 40 years old, and generally associates with squamous cell carcinoma of the upper aerodigestive tract. We describe a 57-year-old woman with the characteristic features of PAB, including violaceous erythematous, scaling eruption, palmoplantar keratoderma and nail dystrophy. Further analysis revealed the underlying neoplasm to be cholangiocarcinoma. The clinical aspects of PAB and associated neoplasms are reviewed.

RESUMO

CONTEXT: Behçet's disease (BD) is a multisystem inflammatory disorder with unknown etiology characterized by recurrent oral and genital aphthous ulcers and uveitis. Behçet's disease can affect the central nervous system. AIMS: We aimed to investigate subclinical neurological involvement in patients who were suffering from BD and who had no neurological symptoms. SETTINGS AND DESIGN: A total of 49 patients were included in the study. For the investigation of subclinical neurological involvement, the patients received imaging and/or neurophysiologic evaluations. MATERIALS AND METHODS: The evaluation techniques were as follows: single photon emission computed tomography, 33 patients; cranial magnetic resonance imaging (MRI), 25 patients; brainstem auditory evoked potential examination, 36 patients; and electroencephalography (EEG), 30 patients. STATISTICAL ANALYSIS USED: The Mann-Whitney U test and Wilcoxon Rank-Sum W test were used. RESULTS: Patients in the MRI and EEG groups showed significantly more abnormalities than did age- and gender-matched controls. CONCLUSIONS: Early diagnosis of neurological involvement in BD is important in reducing or preventing complications. Cranial MRI and EEG were found to be useful for detecting subclinical neurological abnormalities in patients with Behçet's disease.

RESUMO

BACKGROUND: Vitiligo is a common, acquired, pigmentary disorder characterized by the loss of melanocytes. In this study, we evaluated the ophthalmalogic abnomalies of patients with vitiligo with regard to tear functions. METHODS: The patients and control subjects underwent examinations via the Schirmer's test, tear film break-up time (BUT), and Rose Bengal staining. RESULTS: Schirmer test values in patients with vitiligo were lower than those in the control subjects, but the differences were not statistically significant (P = 0.200). In addition, the BUT values of patients with vitiligo were also significantly lower (P < 0.001), and the Rose Bengal scores of patients with vitiligo were significantly higher (P < 0.001) than the scores of the control subjects. When comparing only the vitiligo subgroups, the Schirmer test scores and BUT values of patients with acrofacial vitiligo were significantly lower than those of patients with generalized vitiligo (P = 0.001). Furthermore, the Rose Bengal scores of patients with acrofacial vitiligo were significantly higher than the scores of patients in the generalized subgroup (P = 0.011). CONCLUSION: This study revealed that there is a decrease in tear production in patients with vitiligo, particularly in those with the acrofacial type of vitiligo.

RESUMO

Behçet disease (BD) is associated with endothelial dysfunction and chronic inflammation. The neutrophil-lymphocyte (N/L) ratio and carotid intima-media thickness (cIMT) are markers of inflammation and vascular risk, respectively. We assessed the relationship between cIMT values and N/L ratio in BD (65 patients and 62 control participants). There were statistically significant differences in N/L ratios and cIMT values between the patients with BD and control group (P < .001). There were moderate positive correlations between cIMT value, C-reactive protein, and N/L ratio in patients with BD. Receiver-operating characteristic curve analysis suggested that the optimum N/L ratio cutoff point for patients with BD was 1.29, with a sensitivity, specificity, negative predictive value, and positive predictive value of 97, 77, 96, and 75%, respectively (area under curve: 0.691, 95% confidence interval = 0.600-0.782, P < .001). The N/L ratio may be a useful index of BD activity.

RESUMO

BACKGROUND: Post-adolescent acne has been defined as acne in a patient aged >25 years. Acne vulgaris first develops at the onset of puberty as a result of hormonal changes. During puberty, there is a transient decline in insulin sensitivity. We hypothesized that insulin resistance might persist after puberty in patients with post-adolescent acne. OBJECTIVES: This study was conducted in order to investigate the relationship between post-adolescent acne and insulin resistance. METHODS: The study population comprised 35 patients with post-adolescent acne and 35 healthy control subjects. The parameters measured were fasting blood glucose, insulin, aspartate aminotransferase (AST) and alanine aminotransferase (ALT), total cholesterol (TC), triglycerides, high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C). The homeostasis model assessment of insulin resistance (HOMA-IR) index was calculated for each individual. RESULTS: No significant differences were observed between patients with post-adolescent acne and control subjects in fasting blood glucose, fasting insulin, AST, ALT, triglyceride and HDL-C levels, and HOMA-IR index. There were also no correlations between these parameters and the severity of acne. CONCLUSIONS: This study suggests that insulin resistance may not play a major role in the pathogenesis of post-adolescent acne. Hormonal changes, genetic susceptibility, stress, the use of cosmetics, drugs, and environmental factors should be considered in the development of post-adolescent acne.

RESUMO

Tinea capitis is a fungal infection of the skin and the hair with involvement of the hair shaft and the pilosebaceous unit. It may be the most common of all cutaneous mycoses in children. Tinea capitis can be inflammatory or noninflammatory. It is thought that humoral and cell-mediated immunities play a role in the formation of the clinical types of the disease. We studied twelve patients with acute inflammatory disease, four patients with chronic non-inflammatory disease, and one patient with a black-dot variant of tinea capitis. The composition of inflammatory infiltrates present in lesional skin was analyzed by antibodies to T cells (CD3) and B cells (CD20). Anti-CD3 revealed large numbers of T cells in twelve patients with acute, inflammatory dermatophytosis, whereas anti-CD20 revealed marked infiltrates of both B and T cells in all patients with chronic, non-inflammatory dermatophytosis. As a result, we thought that cell-mediated immunity might play a role in the acute, inflammatory type of tinea capitis and that humoral immunity might do so in the chronic, non-inflammatory type of tinea capitis.

RESUMO

BACKGROUND: The aim of this study is to reveal demographic and clinical features of Behçet's disease (BD) in a Turkish population. METHODS: We retrospectively evaluated the clinical findings of 521 patients with BD. RESULTS: A total of 521 patients (287 female and 234 male) were included in this study. Onset signs: oral ulceration (72.7%) was followed by genital ulceration (3.1%), ocular involvement (1.0%), and erythema nodosum-like lesions (ENLL) (0.2%). In 120 patients (23%), the onset manifestation compromised more than one symptom. During follow-up, in females and males respectively, oral ulceration was found in 100%, genital ulceration in 90.9% and in 82.5%, papulopustular lesions in 52.6% and in 71.4%, positive pathergy test in 45.3% and in 48.7%, ENLL in 43.6% and in 31.6%, ocular involvement in 36.9% and in 58.1%, gastrointestinal involvement in 6.6% and in 5.6%, joint involvement in 4.2% and in 6.4%, vascular involvement in 1.7% and in 10.6%, neurological involvement in 0% and in 4.7% and pulmonary involvement in 0.7% and in 0.7%. Genital ulceration and ENLL were found to be statistically higher in females than males. Papulopustular lesions and ocular, neurological, and vascular involvement were significantly higher in males than females. CONCLUSIONS: In our study, systemic involvement was higher in males than females, as the disease is more severe in males than females. As the only initial finding of the disease can be genital ulceration or ocular manifestations, gynecologists, urologists, ophthalmologists, and family practitioners must keep in mind BD as a differential diagnosis.

RESUMO

BACKGROUND: Helicobacter pylori is a worldwide bacteria that may affect several extra-gastric systems, including the endocrine, hematologic, vascular, respiratory, immune, and skin. Several skin diseases, including chronic urticaria, alopecia areata, psoriasis, and systemic lupus erythematosis have been found to be associated with H. pylori infection. AIM: To our knowledge, there are no data showing an association between H. pylori and vitiligo. Therefore, in this study, we wanted to evaluate the relationship between H. pylori and vitiligo. METHODS: This study is a prospective study carried out in our Gastroenterology and Dermatology and Venereology departments of the Ankara Education and Research Hospital (Ankara, Turkey) between July 2013 and December 2013. Seventy-nine consecutive patients with vitiligo and 72 patients with telogen effluvium (TE) were recruited from the dermatology outpatient clinic. A total of 133 patients with vitiligo (n=68) and TE (n=65) [excluding 18 patients who had suspicious urea breath test (UBT) results] were included in the study. All individuals were tested for H. pylori IgG and CagA. Also, a UBT was performed to detect the presence of H. pylori infection. RESULTS: There were significantly higher rates of H. pylori positivity, H. pylori CagA, and IgG in serum in the vitiligo group than in the TE group (p<0.05). The number of patients with dyspepsia was significantly higher in the vitiligo group than in the TE group. No statistically significant relationship was seen between H. pylori positivity, CagA, H. pylori IgG, dyspepsia, and the Vitiligo Disease Activity score (p>0.05). Also, when patients with vitiligo were divided into localized and generalized types of vitiligo, there was no association between vitiligo involvement pattern and H. pylori positivity, CagA, H. pylori IgG, and dyspepsia (p>0.05). CONCLUSION: Additional studies are necessary to evaluate the effect of H. pylori eradication on the clinical course of vitiligo. Further studies are also needed to explain the relationship between H. pylori and the pathogenesis of vitiligo.

RESUMO

BACKGROUND: The pathergy test (PT) is important in the diagnosis of Behçet's disease (BD). However, misinterpretation of the test might cause false-positive or false-negative results. Therefore, immunopathologic and histopathologic tests are recommended with PT. AIMS AND OBJECTIVES: The aim of this study is to determine histopathologic findings of positive pathergy reaction at BD. MATERIALS AND METHODS: This study was performed on 23 patients with BD. All patients were in active period of the disease. After 48 h from the injection, biopsy was performed on positive pathergy lesions. RESULTS: Of the specimen from positive PT lesions of patients with BD, nine revealed mixed type inflammatory cell infiltration (39.1%), two revealed lobular panniculitis without vasculitis (8.7%), two revealed neutrophil rich infiltration (8.7%), and five revealed lymphocyte rich infiltration (21.7%) at the subcutaneous tissue. Mixed type inflammatory cell infiltration (43.4%), endothelial swelling and thickening (17.3%), erythrocyte extravasation (26.0%), perivascular cell infiltration (13.0%), lymphocytic vascular reaction (8.6%), lymphocytic vasculitis (13.0%), and leukocytoclastic vasculitis (21.7%) were detected in dermis by histopathologic examinations. There was no statistically significant difference between histopathologic findings and sex, family history, and systemic involvement except uveitis. CONCLUSION: This is an exceptional study since it is the first study that determines subcutaneous tissue findings of positive pathergy reaction in Behçet patients. In our study, uveitis was found to be statistically significant in the patients who had vasculitis in dermis. It can be a clue for prediction of disease severity and course. Further, studies that include wide number of patients will better illuminate the correlation between subcutaneous tissue findings and disease severity and clinical course.

RESUMO

Studies that have evaluated autonomic nervous system (ANS) function in Behçet disease (BD) are rare and have indicated conflicting results with different degrees of involvement. The aim of this study was to investigate ANS function by using electrophysiological tests in patients with BD and to determine the relationship between the disease activity parameters and the indicators of autonomic activity. We included 70 BD patients and 50 healthy controls. Demographic characteristics including age, sex, and disease duration were recorded. A detailed neurological examination was performed, and clinical autonomic symptoms were recorded. The Behçet Disease Current Activity Form (BDCAF) was used to determine the disease activity. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels were determined for laboratory activity. The electrophysiological assessments of ANS function were performed by sympathetic skin response (SSR) and R-R interval variation (RRIV) tests. The mean values of sympathetic (SSR latency and amplitude) and parasympathetic (RRIV at rest [R%] and deep breathing [D%], D% - R%, and D%/R%) parameters were compared, and any correlations between ANS parameters and clinical disease characteristics were determined. Seventy BD patients (23 males, 47 females) with a mean age of 41.2 ± 10.01 years and 50 control subjects (18 males, 32 females) with a mean age of 39.5 ± 8.94 years were included in the study. All the subjects were totally symptom free with respect to ANS involvement, and the subjects in both groups had normal neurological examination findings. The demographic characteristics were similar between the groups. The mean latency of SSR was increased (1.4 ± 0.4 vs 0.7 ± 0.8), and R% (0.3 ± 0.3 vs 0.5 ± 0.4) and D% (0.3 ± 0.3 vs 0.6 ± 0.5) values were decreased in BD patients compared to control subjects. No correlation was found between BDCAF scores and ANS variables. However, there was a significant correlation between SSR latency and ESR and CRP values (p < 0.01, r = -0.25, r = -0.31, respectively) in the patient group, indicating a more sympathetic dysautonomia in patients with active laboratory parameters. In conclusion, our study indicates a subclinical sympathetic and parasympathetic autonomic dysfunction in patients with BD, which may be related with disease activity. As the early recognition of abnormalities in ANS may be very important in order to prevent excessive morbidity, simple electrophysiological methods are suggested to identify Behçet patients at high risk for symptomatic dysautonomia.

RESUMO

A 46-year-old man complained of ulcerovegetative lesions in the anogenital region, which he had noted one month prior to presentation. The patient had a history of travel to African countries. Therefore, the ulcerovegetative lesions of the patient were suspected to be granuloma inguinale (GI). Calymmatobacterium granulomatis was not observed in the direct examination of scrapings collected from the base of the ulcerovegetative lesion. Instead, a histological examination revealed cutaneous metastasis of mucinous adenocarcinoma of the rectum. Therefore, a diagnosis of GI was eliminated. As the patient did not report his history of rectal cancer and had travelled to African countries, we had primarily focused on the diagnosis of GI.
