Matrix metalloproteinase-7 could be a predictor for acute inflammation in psoriatic patients.

Purpose: The pathogenesis of psoriasis is characterized by a disruption of extracellular matrix (ECM) in which matrix metalloproteinases (MMPs) participate actively. We aimed to determine MMP-7 level and its association with the inflammatory response in order to determine its usefulness as a biomarker for psoriasis prediction. We also aimed to determine its distribution in uninvolved and involved psoriatic skin to evaluate the probable role of MMP-7 in psoriasis pathogenesis.

In vitro biofilms and antifungal susceptibility of dermatophyte and non-dermatophyte moulds involved in foot mycosis.

Tinea pedis and onychomycosis are among the commonest fungal diseases in the world. Dermatophytes and, less frequently, non-dermatophyte moulds are aetiological agents of foot mycosis and are capable of forming biofilms. Fungal biofilm has demonstrated increasing drug resistance.

Prevalence, Etiology, and Risk Factors of Tinea Pedis and Tinea Unguium in Tunisia.

Background: Foot mycoses are a frequent disease that represents a public health problem worldwide.

Objectives: This study aims to evaluate the epidemiology of foot mycoses among Tunisian patients, in order to determine the fungal etiological agents and to identify possible risk factors.

Patients And Methods: A prospective study of three hundred and ninety-two patients was undertaken during one year (2013-2014).

Keratoacanthoma Centrifugum Marginatum: Response to Acitretin.

A previously healthy 70-year-old woman presented with a 5-month history of an asymptomatic keratotic, papulonodular plaque on her right forearm. The lesion started as a follicular papule followed by progressive peripheral proliferation. No record of trauma, contact with any chemicals, use of immunosuppressive drugs, or history of neoplasm was noted.

Lipomembranous Panniculitis Associated With Venous Insufficiency, Morphea, and Psoriasis.

A 45-year-old obese woman diagnosed with morphea on her leg, presented with a 7-year history of cutaneous depressions on her thigh, chest, and back. She recalled that the lesions followed a three-phase course: edema, hardening, and atrophy. Clinical examination revealed a cutaneous indurated depression localized to the thigh, chest, and the back (Figure 1).

Methotrexate-induced necrolysis in tumoral-stage mycosis fungoides: a challenging diagnosis.

Methotrexate-induced cutaneous ulceration is a rare but potentially serious drug adverse reaction. This adverse reaction of methotrexate therapy has been initially described in psoriasis patients and is unusual in patients with cutaneous T-cell lymphoma. In 1978, Mc Donald et al reported the first three cases of cutaneous ulcerations in patients treated for a mycosis fungoides with intravenous infusions of methotrexate.

MALDI-TOF typing highlights geographical and fluconazole resistance clusters in Candida glabrata.

Utilizing matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectra for Candida glabrata typing would be a cost-effective and easy-to-use alternative to classical DNA-based typing methods. This study aimed to use MALDI-TOF for the typing of C. glabrata clinical isolates from various geographical origins and test its capacity to differentiate between fluconazole-sensitive and -resistant strains.

Comparison of MALDI-TOF mass spectra with microsatellite length polymorphisms in Candida albicans.

Candida albicans is the most frequent yeast involved in human infections. Its population structure can be divided into several genetic clades, some of which have been associated with antifungal susceptibility. Therefore, detecting and monitoring fungal clones in a routine laboratory setting would be a major epidemiological advance.

Phenotypical and molecular characterization of Microsporum canis strains in North-Tunisia.

In this study, 40 Microsporum canis isolates were obtained from different patients from the Mycology Unit of the Hospital La Rabta (Tunis) during a 3 month period. The phenotypic identification was done by morphological characterization and biochemical tests. Molecular analysis was performed by amplification of the ITS region of rDNA, the amplified region was subjected to enzymatic digestion and sequenced to evaluate phylogenetic relationships.

[Severe childhood atopic dermatitis].

Atopic dermatitis (AD) is a chronic relapsing eczematous skin disease. It represents one of the symptoms of atopic diathesis. DA affects usually infants and children.

Proliferative fasciitis in the abdominal region.

A 30-year old man with no trauma history presented to our department of dermatology with a 2-year history of abdominal painful masses. The spontaneous pain and tenderness in the abdominal region gradually worsened. Physical examination revealed 3 firm, irregular subcutaneous nodules measuring 1 x 0.

[Cutaneous carcinoma induced by radiotherapy: a report of 31 cases].

Background: Depilatory radiotherapy was used in the sixties as a treatment for ringworm in Tunisia. Subsequently some of these patients developed radio-induced carcinomas of the scalp.

Aim: To present the epidemiological, clinical, pathological,therapeutic features and out come of radio-induced cutaneous carcinomas.

Lichen planus pemphigoides: four new cases and a review of the literature.

Lichen planus pemphigoides (LPP) is a rare autoimmune blistering disease. It appears to be combination of lichen planus and bullous pemphigoid. We describe four new cases of LPP and discuss the epidemiological, clinical, pathological, and therapeutic features of this singular association through a review of the 74 published cases within the English literature.

A case of pellagra associated with megaduodenum in a young woman.

Pellagra is a rare condition that has been known for many years to be related to niacin deficiency. Clinically known as the 4 "D" symptoms for dermatitis, diarrhea, dementia, and even death, skin changes remain one of the most important features of this pathology, leading frequently to the diagnosis. Pellagra is mostly seen in poor populations with a deficient diet; still, it is sporadically observed in developed countries, usually in association with digestive disorders.

[Tuberculosis of the breast: a rare often unrecognized diagnosis].

Unlabelled: Tuberculosis of the breast (BT) is a rare extrapulmonary localization for tuberculosis that mainly affects young women during their child-bearing years.

Objective: We report eight cases of BT and describe its clinical characteristics, outcomes, and differential diagnoses.

Patients And Methods: This retrospective study collected all cases of BT diagnosed at our hospital's infectious disease department in Tunisia from 2000 through 2009.

Letter: Tinea capitis in infants in their first 2 years of life: A 12-year study and a review of the literature.

Background: Tinea capitis (TC) is a dermatophyte infection that occurs mainly in childhood; but it is uncommon in infants. The aim of this study was to review the clinical and mycological profile of TC in infants.
