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). All subjects were asked to collect demographic data related to the risk factors of foot mycoses. A complete mycological diagnosis was carried out on all patients. Results. A total of 485 samples were collected; tinea pedis and tinea unguium were confirmed in 88.2% of cases. Dermatophytes were isolated in 70.5% and the most frequent pathogen was Trichophyton rubrum (98.1%), followed by yeasts (17.7%) commonly Candida parapsilosis. Non-dermatophyte molds (NDMs) were observed in 8.02% cases and Fusarium sp. was the frequent genus (29.1%). The main predisposing factors of fungal foot infections were practicing ritual washing (56.6%) and frequentation of communal showers (50.5%). Conclusion. This is a recent survey of foot mycoses in Tunisia. Epidemiological studies can be useful to eradicate these infections and to provide further measures of hygiene and education.

Bronchogenic Cyst of the Interatrial Septum Presenting as Atrioventricular Block

Introduction Tuberculosis is endemic in Tunisia Pulmonary tuberculosis is the most common presentation in our country Cutaneous presentations are rare (1–2% of cases) The diagnosis of cutaneous tuberculosis (CT) is difficult Histological and clinical presentations are polymorphous, many differential diagnoses are available, and it is difficult to isolate Mycobacterium  Objective We had for aim to study the epidemiological and clinical features of CT in Tunisia, and to compare presentations before and after 1990 Patients and methods We conducted a retrospective study between January 1991 and December 2011, in which we included all cases of CT observed at the Infectious Diseases and Dermatology Units of the Tunis la Rabta Hospital Results Hundred and thirty-seven patients were included, with a mean age of 438 years; 723% were female patients Hundred and fifty locations were observed, most of which on the head and neck Scrofuloderma was the most frequent presentation, observed in 65% of cases The diagnosis was confirmed by histology and/or microbiology in 758% of cases The treatment was prescribed for a mean 113 months, leading to full recovery in most cases Conclusion CT is still reported in Tunisia The diagnosis relies mainly on histology Controlling this mutilating tuberculosis requires a global control of this disease, and especially lymph node location, given the high rate of scrofuloderma

Cutaneous tuberculosis in Tunisia

Intrabronchial rupture of bronchogenic cyst.

Bronchogenic cyst is a benign congenital developmental abnormality of the embryonic foregut. The skin is a rare site for bronchogenic cysts, and in this location it is often a solitary lesion. It is poorly recognized by clinicians and in almost all cases the diagnosis is established by histopathologic examination. This report documents a new case of multiple cutaneous bronchogenic cysts bilaterally located on the neck and on the scalp, which are unusual locations of this lesion.

Multiple cutaneous bronchogenic cysts located on the neck and the scalp. A case report.

Resume La tuberculose cutanee se caracterise par la multiplicite des formes anatomocliniques. Elle represente 2 % des localisations extrapulmonaires de la tuberculose. Nous rapportons une observation de tuberculose cutanee particuliere par une discordance des aspects anatomoclinique. Cas clinique Nous rapportons le cas d’une patiente de 29 ans, presentant de multiples lesions dont l’aspect clinique evoquait un lupus tuberculeux. L’histologie reproduisait l’aspect d’une tuberculose caseeuse. Le bilan radiologique decouvrait des lesions de tuberculose pulmonaire. L’intradermoreaction a la tuberculine etait positive. La recherche de bacille de Koch etait negative sur les prelevements cutanes et dans les crachats. Les lesions cutanees et pulmonaires ont evolue favorablement sous quadruple antituberculeux. Commentaire Notre patiente illustre les difficultes du diagnostic et de la classification de certaines formes de tuberculose cutanee. La multiplicite des lesions et leur siege, la presence d’une necrose caseeuse a l’histologie, l’association a une tuberculose pulmonaire evolutive ne sont, en effet, pas habituels au cours du lupus tuberculeux.

Le lupus tuberculeux

Resume Introduction Le pied du diabetique est particulierement expose au risque d’infections mycosiques considerees comme facteurs de gravite avec risque de surinfection bacterienne parfois grave. Patients et methode Nous avons mene une etude transversale, portant sur tous les diabetiques hospitalises a l’hopital de jour de l’Institut national de nutrition de Tunis entre janvier et mars 2005. Le but de notre etude etait d’etudier la frequence des mycoses des pieds chez le diabetique (diagnostic porte sur un prelevement mycologique), les facteurs favorisant leur survenue, la flore mycosique du pied chez le diabetique et les eventuelles complications secondaires a ces mycoses. Resultats Durant la periode etudiee, 150 diabetiques ont ete hospitalises. Une mycose du pied a ete retrouvee dans 81 cas (54 % des patients). L’âge des patients, la neuropathie peripherique et l’hypercholesterolemie ont constitue les facteurs favorisant l’apparition de mycose des pieds chez nos patients. L’atteinte des espaces interorteils a constitue le principal siege des mycoses suivie par l’atteinte ungueale et l’atteinte plantaire. Trichophyton rubrum etait le champignon le plus frequent dans toutes les localisations. Les levures etaient principalement observees au niveau des plantes des pieds. Aucune complication n’a ete observee chez nos patients. Discussion et conclusion Si l’âge des patients et la neuropathie peripherique sont classiquement rapportes comme facteurs favorisant la survenue d’une mycose des pieds, les dyslipemies ne sont pas decrites comme telles dans la litterature.
