Latent Tuberculosis in Psoriasis Patients on Biologic Therapies: Real-World Data from a Care Center in Romania.

Background and Objectives: Psoriasis is a chronic and inflammatory condition that has a huge impact on the patient's quality of life. Biological treatment improved psoriasis therapy, with impressive results seen in the evolution of the disease and the patient's quality of life. However, the risk of mycobacterium tuberculosis (MTB) infection reactivation is well-known to biological therapy, which raises problems especially in an endemic country. Materials and Methods: In this study, we followed moderate to severe psoriasis patients who had latent tuberculosis infection (LTBI) following treatment with a biological therapy approved in Romania. Results: The patients were evaluated at baseline and then followed-up with Mantoux tests and chest X-rays every year, resulting in 54 patients being diagnosed with LTBI. At the initial evaluation, 30 patients with LTBI were identified, and 24 more were identified during biological therapy. These patients were given prophylactic treatment. Out of the 97 participants in this retrospective study, 25 required association of methotrexate (MTX) alongside biological therapy. We compared the prevalence of positive Mantoux tests in patients with combined therapy with that of patients only on biological treatment, and the results were higher in the combined therapy group. Conclusion: All the patients in the study were vaccinated against tuberculosis (TB) after birth, and none were diagnosed with active tuberculosis (aTB) before or after the start of therapy according to the pulmonologist.

From Benign Inflammatory Dermatosis to Cutaneous Lymphoma. DNA Copy Number Imbalances in Mycosis Fungoides versus Large Plaque Parapsoriasis.

Background and Objectives: Mycosis fungoides (MF) and large plaque parapsoriasis (LPP) evolution provide intriguing data and are the cause of numerous debates. The diagnosis of MF and LPP is associated with confusion and imprecise definition. Copy number alterations (CNAs) may play an essential role in the genesis of cancer out of genes expression dysregulation. Objectives: Due to the heterogeneity of MF and LPP and the scarcity of the cases, there are an exceedingly small number of studies that have identified molecular changes in these pathologies. We aim to identify and compare DNA copy number alterations and gene expression changes between MF and LPP to highlight the similarities and the differences between these pathologies. Materials and Methods: The patients were prospectively selected from University Clinic of Dermatology and Venereology Timișoara, Romania. From fresh frozen skin biopsies, we extracted DNA using single nucleotide polymorphism (SNP) data. The use of SNP array for copy number profiling is a promising approach for genome-wide analysis. Results: After reviewing each group, we observed that the histograms generated for chromosome 1-22 were remarkably similar and had a lot of CNAs in common, but also significant differences were seen. Conclusions: This study took a step forward in finding out the differences and similarities between MF and LPP, for a more specific and implicitly correct approach of the case. The similarity between these two pathologies in terms of CNAs is striking, emphasizing once again the difficulty of approaching and differentiating them.

A preliminary study of microRNA expression in different types of primary melanoma.

MicroRNAs (miRNAs) have been proven to regulate the development and progression of cancer through various mechanisms. The aim of the present study was to compare miRNA expression between primary melanomas from different sites. We analyzed the expression of 84 miRNAs in 27 primary melanoma and 5 nevus formalin-fixed paraffin-embedded (FFPE) samples using the Human Cancer PathwayFinder miScript miRNA PCR Array. The FFPE samples were obtained from the archives of the Municipal Clinical Emergency Hospital of Timisoara and included 10 cutaneous melanomas, 10 uveal melanomas, 7 mucosal melanomas, and 5 cutaneous nevi. Out of 84 miRNAs, 11 miRNAs showed altered expression in all types of melanoma compared with the nevi. Among these, miR-155-5p, miR-9-5p, miR-142-5p, miR-19a-3p, miR-134-5p, and miR-301a-3p were upregulated, while miR-205-5p, miR-203a-3p, miR-27b-3p, miR-218-5p, and miR-23b-3p were downregulated. The highest similarity in miRNA expression pattern was found between uveal and mucosal melanoma groups, i.e., 15 miRNAs had altered expression in both groups. Overall, we identified several miRNAs with significantly altered expression in primary melanomas, including those reported for the first time in this type of cancer. Among them, mir-9-5p, mir-203a-3p, mir-19a-3p, mir-27b-3p, and mir-218-5p showed altered expression in all three melanoma types vs. nevi. Further research should explore the potential of these miRNAs in melanoma.

Lymphangioma Circumscriptum Post Radiotherapy for Penile Cancer Treated with CO2 Laser.

Lymphangioma circumscriptum (LC) is a rare, benign condition, predominantly characterized by the malformation of lymphatic skin vessels. Its onset may be congenital or due to secondary causes such as radiotherapy, infections, or surgical procedures. We present the case of a 55-year-old patient with a pathologic history of squamous cell carcinoma of the penis followed by radical penectomy. Due to metastasis to the locoregional lymph nodes, the entire affected area was subsequently treated with radiation therapy, receiving a total dose of 55.8 Gray. Eight years after this treatment, translucent vesicles filled with a clear liquid appeared on the scrotum. Histopathology confirmed the diagnosis of LC and therapy with CO2 laser was applied, resulting in a favorable outcome. LC of the scrotum may present a long-term radiotherapy-induced complication of this site. Our clinical experience showed that the CO2 laser was the therapy of choice as the vesicles entirely disappeared and healed as white scar-like lesions.

CNARA: reliability assessment for genomic copy number profiles.

BACKGROUND: DNA copy number profiles from microarray and sequencing experiments sometimes contain wave artefacts which may be introduced during sample preparation and cannot be removed completely by existing preprocessing methods. Besides, large derivative log ratio spread (DLRS) of the probes correlating with poor DNA quality is sometimes observed in genome screening experiments and may lead to unreliable copy number profiles. Depending on the extent of these artefacts and the resulting misidentification of copy number alterations/variations (CNA/CNV), it may be desirable to exclude such samples from analyses or to adapt the downstream data analysis strategy accordingly. RESULTS: Here, we propose a method to distinguish reliable genomic copy number profiles from those containing heavy wave artefacts and/or large DLRS. We define four features that adequately summarize the copy number profiles for reliability assessment, and train a classifier on a dataset of 1522 copy number profiles from various microarray platforms. The method can be applied to predict the reliability of copy number profiles irrespective of the underlying microarray platform and may be adapted for those sequencing platforms from which copy number estimates could be computed as a piecewise constant signal. Further details can be found at https://github.com/baudisgroup/CNARA . CONCLUSIONS: We have developed a method for the assessment of genomic copy number profiling data, and suggest to apply the method in addition to and after other state-of-the-art noise correction and quality control procedures. CNARA could be instrumental in improving the assessment of data used for genomic data mining experiments and support the reliable functional attribution of copy number aberrations especially in cancer research.

Cutaneous lymphoma misdiagnosed as chronic lymphadenitis.

Cutaneous lymphomas (CLs) represent a group of lymphoproliferative disorders that can be difficult to diagnose in the early stage because they could mimic many benign inflammatory dermatoses (chronic eczema, bullous dermatosis, idiopathic erythroderma, psoriasis, lymphadenitis). Primary cutaneous B-cell lymphomas are a unique and controversial group of skin lymphomas characterised by the absence of extracutaneous manifestations at diagnosis. We present the case of a 60-year-old man with 7-month history of a growing inguinal mass/tumour, which was misdiagnosed as inguinal chronic lymphadenitis. Recognition of the correct entity, primary cutaneous diffuse large B-cell lymphoma leg type, led to an appropriate therapeutic strategy, knowing that these types of tumours behave more aggressively than other types of primary cutaneous B-cell lymphomas. The patient was discharged with rituximab + chemotherapy indication and favourable outcome. The aim of the presentation is to describe these common skin manifestations, however seen in a primary cutaneous B-cell lymphoma, which underlines the necessity of rigorous monitoring/long-term follow-up as well as exhaustive histopathological analysis for the diagnosis.

Unusual foreign body in the sigmoid colon, chronic alcohol abuse, and Fournier gangrene: a case report.

Fournier gangrene (FG) is an infectious condition with fulminant evolution and is sometimes life-threatening. Here, we present the case of an immunocompromised 59-year-old male with surgical history of a pancreatic pseudocyst stented endoscopically. After unrecognized stent migration in the sigmoid without colonic perforation, he developed severe necrosis of the scrotum and perineum, which spontaneously perforated, presenting a smell suggesting moist gangrene. FG that has spread to the male genital organs presents therapeutic challenges. The purpose of our study is to present this case, typical for FG, with an educational aim both for the internal and surgical specialties, and the goal of further multidisciplinary collaboration for the optimal management of the patient with personalized treatment.

Mucosal melanomas in the elderly: challenging cases and review of the literature.

Melanomas are malignant tumors that originate from melanocytes. They are most frequently localized in the skin, but 5% of all melanomas interest also extracutaneous sites as mucosal surfaces, parenchymatous organs, the retroperitoneum area, and the ocular ball. The purpose of this study was to investigate the epidemiologic and morphologic data of mucosal melanomas diagnosed at Emergency City Hospital (Timisoara, Romania) during a period of 12 years. The study included 17 cases of extracutaneous, extraocular melanomas, with 16 primary melanomas and one secondary melanoma. All our patients were older than 53 years and were mostly men. Most of the patients presented with localized disease; only one case had regional lymph node metastases, and another one had systemic metastases at the time of diagnosis. Regarding localization, nine of 16 melanomas were in the head and neck region, six were diagnosed in the gastrointestinal and urogenital tracts (three cases each), and one case had a rare localization (retroperitoneum). The most common histologic type was represented by epithelioid cells, and the majority of the tumors were achromic. Mucosal melanoma is a tumor associated with aging, all our patients being older than 53 years. Because of unspecific symptoms and low incidence, the diagnosis is often delayed and requires teamwork among the clinician, pathologist, radiologist, and oncologist. Different genetic fingerprints impose a correct diagnosis to offer the patient the best novel, personalized therapy.

Improvement in severe psoriasis associated with isoniazid treatment.

A 67 year-old man was diagnosed 10 years ago with severe plaque psoriasis and was hospitalized for re-evaluation of therapy. He was treated previously with topical corticosteroids, methotrexate, and phototherapy. As part of the assessment protocol for initiation of biological treatment, a tuberculin skin test was done, which was positive without signs of active tuberculosis. Isoniazid therapy was started with marked improvement of psoriatic lesions before biologic treatment could be initiated.

Ingrown toenails (unguis incarnatus): Nail braces/bracing treatment.

Nail bracing is a safe, simple, and inexpensive treatment option that avoids surgery, requires no anesthetic, requires no recovery period, allows wearing the existing shoes, offers immediate relief from pain, and allows the practice of daily activities. Braces can be used for prolonged periods of times. If recurrence occurs, reapplication of bracing is usually required.

Life satisfaction and beliefs about self and the world in patients with psoriasis: a brief assessment.

BACKGROUND: Psoriasis is a chronic skin condition that can decrease the level of self-esteem, leading to self-devaluation, emotional distress, irrational beliefs and discomfort in everyday life. In this study, we aimed to provide a deeper understanding of lifestyle satisfaction and to identify the nature and magnitude of irrational beliefs in patients with psoriasis. MATERIAL AND METHODS: A two-year case-control study was carried out between 2010 and 2012. The study enrolled 100 consecutive patients with psoriasis vulgaris, admitted to a dermatology clinic and 101 healthy volunteers with similar demographic characteristics, willing to subject themselves to the testing. A series of standardized questionnaires were used, including: The Anamnestic Questionnaire, The General Attitudes and Beliefs Scale - Short version, The Rosenberg Self-Esteem Scale, The Self-Efficacy Scale and The Unconditional Self-Acceptance Questionnaire. RESULTS: The tests revealed a strong correlation between the presence of the disease and the decrease of subject's satisfaction regarding: body satisfaction, sexual satisfaction, social satisfaction, family satisfaction, professional satisfaction and satisfaction concerning their own health condition; p<0.01. There were highly significant differences with a large effect regarding the level of irrational beliefs between the two groups of subjects (p<0.01; f > 0.35). CONCLUSION: The focus on psychological impacts of the disease provides important data for a holistic approach to patients with psoriasis. Effective cooperation between all the parties involved (physicians, family and social network) is necessary to improve the patient's psychological status.

The cytotoxicity of dental alloys studied on cell culture.

The metal alloys used in dental practice are the subject of numerous discussions referring to the effect they have on oral cavity tissues. Numerous scientists established that the organic molecules did not exert a significant influence on the degradation of metallic implants. The aim of this study was to test the cytotoxic potential of the most used dental alloys, the Ni-Cr alloy and the Co-Cr alloy. The tests were made on cell culture of pure cell line dermal fibroblasts and of those obtained from skin biopsies, for both, dental alloys and their eluates. The results were compared with control samples. At seven days after inoculation, we observed the relative similarity between the Ni-Cr alloy and the Co-Cr alloy, where the cells did not detach from the plate and they grow to the edge of the material. In case of the eluates, there were no fragments detached, the cells having a relatively high confluence. Therefore, the cytotoxic effects of the two alloys are similar, even if there are speculations in the literature according to which Ni-Cr alloys would have a more pronounced effect. In conclusion, our study revealed non-cytotoxicity of these two dental alloys, and we believe so they can be used successfully in dental practice.

Cutaneous factitia in elderly patients: alarm signal for psychiatric disorders.

BACKGROUND: The factitious disorders, more commonly known in daily practice as pathomimia, are expressed in dermatology units by skin lesions induced voluntarily by the patient, in order to draw attention of the medical staff and/or the family members. The disorder is often challenging to diagnose and even more difficult to document in front of the patient or relatives. It represents a challenge for the physician, and any attempt at treatment may be followed by recurrence of the self-mutilation. This paper describes two cases of pathomimia diagnosed by dermatologists and treated in a psychiatry unit, highlighting the importance of collaboration in these situations. PATIENTS AND METHODS: Two case reports, describing old female patients with pathomimia, hospitalized in a department of dermatology for bizarre skin lesions. RESULTS: The first case was a 77-year-old female with unknown psychiatric problems and atrophic skin lesions on the face, self-induced for many months, with multiple hospitalizations in dermatology units, with no response to different therapeutic patterns, and full recovery after psychiatric treatment for a major depressive syndrome. The second case was a 61-year-old female patient with disseminated atrophic scars on the face, trunk, and limbs. She raised our interest because of possible psychiatric issues, as she had attempted to commit suicide. The prescription of antidepressants led to a significant clinical improvement. CONCLUSION: These cases indicate that a real psychiatric disease may be recorded in patients suffering from pathomimia. Therefore, complete psychiatric evaluation in order to choose the proper therapy is mandatory for all these cases. Dermatologists and all physicians who take care of old patients must recognize the disorder in order to provide optimum care for this chronic condition. We emphasize therefore the importance of psychiatric evaluation and treatment to avoid the major risk of suicide. Skin lesions must be regarded as an alarm signal in critical cases, especially in senior people.

Biopsying parapsoriasis: quo vadis? Are morphological stains enough or are ancillary tests needed?

BACKGROUND: Parapsoriasis represents a group of cutaneous disorders that shows variable clinical aspects somehow resembling to psoriasis, how is reflecting by its name. It was first named by Brocq, in 1902, as an entity with three components: pityriasis lichenoides, small plaque parapsoriasis and large plaque parapsoriasis. Nowadays, under the name of parapsoriasis are included only the last two categories, that are considered disorders characterized by the presence of a mononuclear infiltrate in the dermis, composed of T-cells. Until now, there were not established pathognomonic histopathological features to diagnose parapsoriasis. AIM: The aim of the study was to investigate the epidemiological and morphological data of parapsoriasis cases diagnosed at Emergency City Hospital, Timisoara, Romania for a period of 12 years. MATERIALS AND METHODS: The study had two parts; one was retrospective and another one prospective. For the retrospective part, we searched 210111 patient files recorded in our Pathology Service for a period of 11 years, from January 2002 to December 2012. The slides were searched from the archive and re-read by two individual pathologists. For prospective part of the study, we reviewed 11815 histological slides read between January and June 2013. After inspection of the recorded files, the pathologists noted, were available, the localization and number of the lesions, together with symptoms. The biopsied specimens were initially processed with routine histological technique, the archive slides being stained with Hematoxylin and Eosin. While reading the slides, the pathologists paid attention to the architecture of the epidermis, the presence of epidermotropism and interface dermatitis, type of the dermal infiltrate and its distributions. CONCLUSIONS: In the present study, we emphasized the histopathological aspects of parapsoriasis in order to create a basic line that could help in the establishment of a uniformly accepted definition of parapsoriasis on histopathological grounds.

Epidemiological aspects of genital warts in romania - a 2012 retrospective survey.

OBJECTIVES: Genital infection with human papillomavirus (HPV) has become one of the most frequently viral sexually transmitted diseases. The infection may remain asymptomatic, may take the form of external genital warts and may give raise to cervical cancers. The aim of this study was to assess the frequency of the patients with genital warts addressing to five tertiary referral dermato-venereological units in Romania (where patients from several counties are referred) and to compare the results with the out-patient data reported by all Romanian hospitals. MATERIAL AND METHODS: Data regarding patients with external genital warts who addressed to the hospital emergency rooms, in five tertiary referral dermato-venerological units in Romania (Bucharest, Timisoara, Craiova, Constanta, Târgu-Mures) were collected for the year 2012. For comparison there have been used data collected by the National School of Public Health, Management and Professional Development, during the same year. OUTCOMES: Data reported at national level in 2012 included 952 patients (731 women and 221 men) with 26 males under 20 years of age and 251 female patients in the age group 0-20 years. In the overall population (males and females combined) the total number of genital warts cases registered at the hospital emergency rooms in the five centers, in the year 2012, was 266 patients (119 men and 147 women) with 4 girls under 14 years of age and 6 male patients in the age group 0-14 years. CONCLUSIONS: The high prevalence of the infection with HPV, the costs of treatment and the psychological impact prove that prevention of the disease is the most important step for decreasing the incidence of this disease. General measures for patients awareness regarding the disease and its complications need to be completed with the recommendation for vaccination. A closer monitoring of patients would provide information for a strategic national approach leading to a better outcome.
