Extensive bullous lichen sclerosus et atrophicus

Abstract Lichen sclerosus et atrophicus is a chronic disease of unknown etiology characterized by atrophic and sclerotic plaques in both genital and extragenital regions. Extensive bullous lichen sclerosus et atrophicus (BLSA) is a severe variant of the disease with no widely accepted treatment. We present a 63-year-old woman with extensive extragenital, ivory-colored, atrophic plaques on her trunk and extremities and disseminated hemorrhagic bullae. The patient was unsuccessfully treated with standard topical corticosteroid therapy, doxycycline and chloroquine. According to the literature, there is little evidence of the efficacy of doxycycline and hydroxychloroquine in the treatment of BLSA. We report a rare case of extensive BLSA that is unresponsive to these drugs.

Prevalence and antibiotic susceptibility of Mycoplasma hominis and Ureaplasma urealyticum in genital samples collected over 6 years at a Serbian university hospital.

BACKGROUND: Mycoplasma hominis and Ureaplasma urealyticum are implicated in a wide array of infectious diseases in adults and children. Since some species have innate or acquired resistance to certain types of antibiotics, antibiotic susceptibility testing of mycoplasma isolated from the urogenital tract assumes increasing importance. AIMS: To evaluate the prevalence and antibiotic susceptibility of M. hominis and U. urealyticum in genital samples collected between 2007 and 2012. METHODS: Three hundred and seventy three patients presenting with symptoms of sexually transmitted diseases, infertility or risky sexual behaviour, who had not taken antibiotics in the previous 6 weeks and had ≥10 WBC per high power field on genital smears were studied. Urethral samples were taken in men and endocervical samples in women. The mycoplasma IST-2 kit was used for organism identification and for testing susceptibility to doxycycline, josamycin, ofloxacin, erythromycin, tetracycline, ciprofloxacin, azithromycin, clarithromycin and pristinamycin. RESULTS: U. urealyticum was isolated from 42 patients and M. hominis from 11 patients. From 9.8% of isolates, both organisms were grown. All M. hominis isolates were resistant to tetracycline, clarithromycin and erythromycin while U. urealyticum was highly resistant to clarithromycin (94.6%), tetracycline (86.5%), ciprofloxacin (83.8%) and erythromycin (83.8%). M. hominis was sensitive to doxycycline (83.3%) and ofloxacin (66.7%) while most U. urealyticum strains were sensitive to doxycycline (94.6%). LIMITATIONS: Inability of the commercial kit used in the study to detect other potentially pathogenic urogenital mycoplasmas (Ureaplasma parvum, Mycoplasma genitalium). CONCLUSION: There is significant resistance of U. urealyticum and M. hominis to tetracycline and macrolides. The most active tetracycline for genital mycoplasmas was found to be doxycycline, which continues to be the drug of first choice.

The Children's Dermatology Life Quality Index (CDLQI): linguistic and cultural validation in Serbian.

BACKGROUND: The Children's Dermatology Life Quality Index (CDLQI) evaluates the impact of skin diseases on the patient's quality of life. OBJECTIVE: The purpose of the study was to translate and to validate the CDLQI into Serbian. METHODS: The CDLQI was translated into Serbian following international recommendations for translation and cultural adaptation. The validation study was carried out on a large cohort of secondary schoolchildren who self-reported acne. RESULTS: Translating the CDLQI consisted of forward translation, reconciliation, back translation, back-translation review, and cognitive debriefing. The good internal consistency of the scale was demonstrated with a Cronbach alpha coefficient of 0.87. A Spearman correlation coefficient of 0.66 between the CDLQI and the Cardiff Acne Disability Index (CADI) was deemed satisfactory to demonstrate concurrent validity. CONCLUSION: The translation, cross-cultural adaptation, and psychometric qualities of the CDLQI were satisfactory, enabling its application in clinical practice and future studies.

Quality of life in patients with toenail onychomycosis.

Onychomycosis is a common, chronic fungal nail infection that can have a significant negative impact on patients' physical and social functioning and emotional well-being. This study was undertaken to assess health-related quality of life (HRQoL) in patients with toenail onychomycosis. The Onychomycosis QoL questionnaire (ONYCHO), as a disease-specific instrument, and the Short Form 36 Health Survey (SF-36) as a generic instrument, were applied in 140 consecutive patients affected by onychomycosis. Women and patients who were experiencing toenail onychomycosis for more than 2 years were reporting worse disease-specific HRQoL. The patients working in blue-collar occupations and patients with greater involvement of individual nails were more affected by onychomycosis regarding symptoms. The results of this study confirm that although onychomycosis is not a life-threatening disease, it can significantly reduce patients' QoL.

The Cardiff Acne Disability Index (CADI): linguistic and cultural validation in Serbian.

PURPOSE: The aims of this study were to translate the Cardiff Acne Disability Index (CADI) into Serbian and to assess its validity and reliability in Serbian acne patients. METHODS: The CADI was translated and linguistically validated into Serbian according to published guidelines. This version of CADI, along with the Serbian version of Children's Dermatology Life Quality Index (CDLQI) and a short demographic questionnaire, was administrated to a cohort of secondary school pupils. The Global Acne Grading Score was used to measure the clinical severity of acne. The internal consistency reliability of the Serbian version of CADI was assessed by Cronbach's alpha coefficient while its concurrent validity was assessed by Spearman's correlation coefficient. Construct validity was examined by factor analysis. RESULTS: A total of 465 pupils completed questionnaires. Self-reported acne was present in 76% of pupils (353/465). The Serbian version of CADI showed high internal consistency reliability (Cronbach's alpha coefficient = 0.79). The mean item-total correlation coefficient was 0.74 with a range of 0.53-0.81. The concurrent validity of the scale was supported by a moderate but highly significant correlation with the CDLQI (Spearman's rho = 0.66; P < 0.001). Factor analysis revealed the presence of two dimensions underlying the factor structure of the scale. CONCLUSIONS: The Serbian version of the CADI is a reliable, valid, and valuable tool for assessing the impact of acne on the quality of life of Serbian-speaking patients.

Quality of life among schoolchildren with acne: results of a cross-sectional study.

BACKGROUND: Acne is a common problem in adolescent children and has a considerable impact on their quality of life. AIMS: The purpose of this study was to assess health-related quality of life (HRQoL) among Serbian adolescents with acne, using 2 questionnaires: The Children's Dermatology Life Quality Index (CDLQI) and the Cardiff Acne Disability Index (CADI) and to provide a cross validation of 2 scales. METHODS: This cross-sectional study was conducted among the pupils of the secondary railway-technical school in Belgrade, Serbia. 478 pupils (aged 15 - 18 years) completed 2 HRQoL questionnaires: CDLQI and CADI. We used t-test for differences between mean values of CDLQI and CADI and Spearman's rho coefficient for correlation between 2 questionnaires. RESULTS: Self-reported acne was present in 71.6% of pupils (64.3% boys and 35.7% girls). The overall mean CDLQI score (4.35 of max. 30) and the overall mean CADI score (3.57 of max. 15) were low, indicating a mild impairment of HRQoL among adolescants. There was good correlation between the 2 questionnaires (Spearman' rho = 0.66). CONCLUSION: The CADI and the CDLQI questionnaires represent simple and reliable instruments for the assesment of HRQoL among schoolchildren with acne. In this study, we identified 17% of boys and 18% of girls perceived their acne as a major problem. It is important to detect and treat such adolescents on time to reduce the psychosocial burden associated with acne.

[Chlamydia trachomatis and urogenital mycoplasms in nonconococcal urethritis in men].

INTRODUCTION: Nongonococcal urethritis is the most common sexually transmitted infection in men, with vast majority of the etiological agents such as Chlamydia trachomatis, followed by urogenital mycoplasmas. The aim of this study was to determine the prevalence of Chlamydia trachomatis, Ureaplasma urealyticum and Mycoplasma hominis in nongonococcal urethritis in men, and to examine infections associated with these agents. Material and methods 299 sexually active, heterosexual men with nongonococcal urethritis were included into the study. Urethral samples were taken with a dacron swab placed into the urethra up to 2-3 cm. The Direct immunofluorescence technique was performed for identification of Chlamydia trachomatis. Ureaplasma urealyticum and Mycoplasma hominis were detected with Mycoplasma IST assay. RESULTS: Chlamydia trachomatis was detected in 22.75%, Uraeplasma urealyticum in 21.08% and Mycoplasma hominis in 8.02% cases. We found no significant differences in prevalence between Chlamydia trachomatis and Ureaplasma urealyticym (p > 0.05). Monoinfections were found in 51.85% with significantly higher rate (p < 0.01) than associated infections (11.70%). Among associated infections, coinfection of Chlamydia trahomatis and Ureaplasma urealyticum was predominant. Association of Chlamydia trachomatis with urogenital mycoplasmas was significantly higher (p < 0.05) than the one between Ureaplasma urealyticum and Mycoplasma hominis. In 36.45% patients no patogenic microorganisms were detected. CONCLUSION: These results confirmed the etiological role of Chlamydia trachomatis and urogenital mycoplasmas in nongonococcal urethritis with prevalence of 51.85% in monoinfections and 11.70% in associated infections. In 36.45% of cases the etiology of urethritis was not elucidated. These results suggest that more sensitive diagnostic tool should be applied when searching for the derailed etiology of nongonococcal urethritis.

Unilateral multiple lichen striatus treated with tacrolimus ointment: a case report.

A previously healthy 11-year-old boy with multiple, unilateral lichen striatus (LS) on the left side of the body is described. The distribution of the lesions corresponded to the lines of Blaschko. Histology of the lesional skin was compatible with LS. Two years after the onset of the linear eruption, treatment with tacrolimus ointment resulted in significant improvement over a short period of time. To our knowledge, this is the first time that the use of tacrolimus for successful treatment of LS with multiple lesions has been reported.

[Dermatomyositis associated with metastatic rectal adenocarcinoma: case report].

INTRODUCTION: Dermatomyositis is an idiopathic inflammatory myopathy with characteristic cutaneous changes. The disease belongs to paraneoplastic dermatosis. Association of dermatomyositis with malignant conditions has been described in various studies. We present a patient with paraneoplastic dermatomyositis associated with metastatic rectal adenocarcinoma. CASE REPORT: A 66-year-old man was hospitalized in our Institute due to skin changes and myopathy in October 2006. According to the medical documents and history, he underwent surgery because of rectal adenocarcinoma in April 2006. Skin changes appeared 5 months before, while aggravation occurred 6 months after the surgery. The diagnosis of dermatomyositis was based on: characteristic clinical picture; the elevated serum level of following enzymes: creatinine kinase, lactate dehydrogenase; the presence of anti-Mi 2 antibodies in serum; electromyographic finding; and by histology of the muscle biopsy. Paraneoplastic nature of dermatomyositis was confirmed by computer tomography of the abdomen which revealed multiple deposits in the liver, by explorative laparotomy showing peritoneal dissemination and histopathological analysis that verified metastatic adenocarcinoma of the rectum. The oncological consulting team suggested chemotherapy which was not carried out because of the rapid lethal outcome. CONCLUSION: We report a case of paraneoplastic dermatomyositis associated with metastatic rectal adenocarcinoma and lethal outcome, and suggest a comprehensive evaluation of patients with dermatomyositis older than 50 years in order to exclude or verify the occult malignancy.

Two cases of probable endogenous extensive cutaneous larva migrans in Serbia.

Cutaneous larva migrans (CLM) is a skin infestation clinically characterized by erythematous serpiginous lesions caused by nematode larvae, usually of animal hookworms. It is most commonly seen in tropical and subtropical geographic areas. It is occasionally seen in Europe and other temperate climates, most often in patients that have previously traveled to tropical areas. We present two male patients that did not travel abroad with clinical features of extensive CLM located on the trunk acquired in an unusual way. CLM is not characteristic of Serbia, which is located in southeast Europe Unusually hot and sunny weather with heavy rainfall and high humidity during the summers of 2005 and 2006 were favorable conditions for the development of parasites in the soil and infestation with large numbers of larvae. To the best of our knowledge, this is the first report of extensive CLM in Serbia.

Contact sensitivity in patients with venous leg ulcers in Serbia: comparison with contact dermatitis patients and relationship to ulcer duration.

BACKGROUND: Contact hypersensitivity is a common occurrence in patients with chronic venous leg ulcers (CVLU) with allergen profiles depending upon the local treatment policies. OBJECTIVE: This study was to determine the frequency of contact sensitivity, prevalence of individual allergens, polyvalent sensitization, and/or their relationship to ulcers duration in the population of CVLU and contact dermatitis patients in Serbia. PATIENTS: 75 patients with CVLU and 82 patients with clinically suspected contact dermatitis were prospectively included in the study. The patients were patch tested with a series of 21 standard and 22 supplemental allergens. RESULTS: 73% (n = 55) of CVLU and 52% (n = 43) of control subjects had 1 or more positive patch test results (P < 0.01). Polysensitization was found in 53% of patients and 21% of controls (P < 0.01). CVLU patients run 2.5 and 4.3 higher risk for contact sensitization and polysensitization, respectively. The most common allergens were Balsam of Peru (21.3%), carba mix (18.7%), fusidic acid (17.3%), colophony (13.3%), paraben mix (12%), chloramphenicol (12%), silver nitrate (12%), and neomycin (10.7%). Polivalent sensitization and higher mean number of allergens were associated with ulcer duration >5 years. CONCLUSIONS: The results confirm a high rate of contact (poly)sensitization in patients with CVLU and local variability in allergen prevalence.

[Specific dermatoses of pregnancy--new classification and differential diagnosis].

INTRODUCTION: The specific dermatoses of pregnancy represent heterogeneous group of pruritic skin disorders that occur exclusively in pregnancy. SPECIFIC DERMATOSES OF PREGNANCY: The updated classification proposed subdividing specific dermatoses of pregnancy into four main categories: 1. atopic eruption of pregnancy; 2. polymorphic eruption of pregnancy; 3. pemphigoid gestationis; 4. intrahepatic cholestasis of pregnancy. Severe pruritius, which is the main symptom in all 4 entities, can impair maternal quality of life. Significant maternal risks are not associated with specific dermatoses of pregnancy; however, pemphigoid gestationis and intrahepatic cholestasis of pregnancy are associated with fetal risks. CONCLUSION: Pathognomonic laboratory tests are not available, except direct immunofluorescence which is diagnostic of pemphigoid gestationis and elevated serum level of bile acids of intrahepatic cholestasis of pregnancy. Characteristic clinical features provide discrimination between polymorphic eruption of pregnancy and atopic eruption of pregnancy.

Male urethritis with and without discharge: relation to microbiological findings and polymorphonuclear counts.

OBJECTIVE: We studied the relation between the presence or absence of urethral discharge, urethral pathogens, and polymorphonuclear (PMN) counts on Gram stained urethral smears in men with symptomatic urethritis. METHODS: The study population was composed of 630 sexually active heterosexual men (aged 18-45 years) who had urethral symptoms and signs (discharge, dysuria or urethral discomfort). Participants were divided into two groups: the first (n=320) was comprised of men with urethral discharge confirmed on examination, while the other (n=310) was composed of patients with urethral symptoms but without discharge. Urethral swabs for Gram stained smears and microbiological analyses (N. gonorrhoeae, C. trachomatis, T. vaginalis and U. urealyticum) were taken from all study participants. Polymorphonuclear leukocytes (PMN) on Gram-stained urethral smears were counted in 5 oil immersion x1000 PMN per high power fields (phpf). Urethritis was defined as the presence of > or =5 PMN/hpf. RESULTS: N. gonorrhoeae was isolated only in men with urethritis accompanied by discharge. The prevalence of T. vaginalis, C. trachomatis and U. urealyticum was significantly higher (F=8.854, P<0.01) in urethral swabs of urethritis patients with discharge compared to patients with no discharge. The most common urethral pathogen in both groups of patients was T. vaginalis (31.56% and 26.45%, respectively). One or more microorganisms were isolated in 258 (81%) subjects with urethritis with discharge, and in 166 (53.5%) urethritis patients without discharge. There was a positive correlation between the significant number of PMN in Gram stained urethral smears and positive microbiological findings in men with urethritis both with and without urethral discharge (Spearmanns coefficients rho=0.986 and rho=0.993, respectively; P<0.01). CONCLUSIONS: The study found a relatively high prevalence of T. vaginalis among our men with urethritis irrespective of the presence or absence of urethral discharge, and showed that taking into account both discharge found on examination, and relevant PMN counts on Gram stained urethral smears fails to detect only 4.2% of oligosymptomatic urethritis patients who are infected with one of the strict urethral pathogens.

[Therapeutic aspects of trichomoniasis]. / Terapijski aspekt trihomonijaze.

INTRODUCTION: Trichomoniasis is frequent, parasitic and sexually transmitted infection of genitourinary tract. It is treated by metronidazole (5-nitroimidazole), according to protocol recommended by Center for Disease Control (CDC, formerly called: Communicable Disease Center) [19]. The resistance of Trichomonas vaginalis (TV) strains to metronidazole (MND) was described in USA in 1960, and later on in many European countries [8, 9, 10, 11, 12, 13]. In these cases, due to persistent trichomonas infection, it is necessary to repeat MND treatment with moderate modification of dose and/or length of its application. Nevertheless, oncogenic and toxic effects of MND have to be taken into consideration. AIM: The aim of this study was to investigate and analyse the incidence of TV in STD and lower susceptibility of certain TV strains to MND were analyzed. METHODS: In three-year period (1999-2001) 612 patients (244 females and 368 males) suspected of STD were examined clinically and microbiologically at the Institute of Dermatovenereology in Belgrade. The patients detected for TV were treated according to CDC protocol. The affected were considered cured if there was no manifest clinical infection, and no TV verified by microbiological test. RESULTS: TV was isolated in 216 patients (35.29% of all subjects). Trichomonas infection was found in 90 (36.88%) out of 244 tested females and in 126 (32.34%) of 368 males. Clinically manifested infection, with extensive urethral and vaginal secretion, was recorded in 161 patients, while the asymptomatic form was found in 55 subjects. This result indicates the predominance of manifested trichomonas infections (75.54% of cases). The difference of distribution of clinical forms of trichomoniasis, in relation to sex, was not statistically significant (chi 2 = 0.854; p > 0.05). The patients with verified trichomonas infection were treated by metronidazole according to CDC protocol. The recommended therapeutical scheme consisted of three phases proceeding in succession, in so far TV had not been eliminated by previous one. The number of cured patients, according to therapeutical phases, was shown in Table 4. Three patients (1.39%, 2 males and 1 female) were not cured in spite of all three completed phases of therapeutical protocol. In all three cases, TV was eliminated by MND application in dose of 3 g/daily, during two days. The failure of minute MND treatment was analyzed in relation to clinical forms of the infection (manifested or asymptomatic), as well as in relation to types of infection (single- or associated infection). The incidence of refractory trichomoniasis treated by a single metronidazole dose of 2 g was significantly higher in the group of patients with polyinfection (c2 = 18.270; p < 0.01). There was no significant difference of resistance to a single MND dose between the groups with manifested and asymptomatic trichomoniasis (chi 2 = 0.321; p < 0.01). DISCUSSION: The prevalence of TV in vaginal and urethral smears indicates the significant incidence of trichomoniasis in STD. TV was more frequently isolated in patients with clinically manifested infection. TV susceptibility to MND was tested in vitro in aerobic and anaerobic conditions. The resistance of strains under in vitro conditions did not correlate with refractory feature of trichomoniasis to MND application [7, 17, 18]. The success of trichomoniasis treatment depends upon multiple factors, including: a) TV susceptibility to drug, b) intravaginal redox potential, c) drug concentration in situ, d) associated microorganisms that may modify the amount of the drug available in situ [7, 18, 21]. The results of our investigation argue for the latter item, verifying that TV resistance to MND is higher in patients with polyinfection in relation to those with monoinfection (significant difference, chi 2 = 18.270; p < 0.01). Repeated administration of low metronidazole doses may prolong the therapy of trichomonas infections, while application of high doses (over 3 g/day) may result in undesired complications. Given the well-known fact that repeated sublethal doses induce the resistance, would it be more beneficial to begin with slightly higher metronidazole dose (3 g/day) during short period of time (3-5 days)? This will be the subject of our further investigation.
