Bullous Pemphigoid Associated With Dipeptidyl Peptidase-4 Inhibitors: A Case Report and Review of Current Evidence.

Dipeptidyl peptidase-4 inhibitors (DPP-4i), or gliptins, are a widely used glucose-lowering agents. A growing amount of evidence pointed to a possible role of DPP-4i in the induction of bullous pemphigoid (BP), which is an auto-immune skin blistering disease that mainly affects the elderly. In this article we discuss a case of DPP-4i associated BP and we provide an updated review of the current knowledge regarding this emerging entity.

Dermoscopy of Onychomycosis: A Systematic Review.

Introduction: Onychomycosis represents a global burden accounting for about 50% of nail consultations. Several studies have tried to assess the dermoscopic features of onychomycosis. With the multiplication of papers, several "new" dermoscopic signs keep being added leading to some inconsistency in onychoscopic terminology.

Whitish patches on the buccal mucosa: Role of dermoscopy.

Morsicatio is caused by chronic self-inflicted biting of the buccal mucosa that results in clinically whitish plaques. It is frequently confused with other dermatological mucosal disorders. To avoid needless invasive procedures, dermoscopy can help with differential diagnosis.

Efficiency and herding analysis in gold-backed cryptocurrencies.

This study analyses and compares the behavior of the gold-backed, conventional cryptocurrency, and gold markets capable of detecting the existence of herding and deducing the efficiency degree. In addition, this empirical work tried to examine the COVID-19 pandemic's influence on both cryptocurrency performances. This work developed a new method that discloses herding biases using persistence and efficiency metrics.

How the cryptocurrency market has performed during COVID 19? A multifractal analysis.

Cryptocurrency markets are complex systems based on speculation. Where investors interact using strategies that generate some biases responsible for endogenous instabilities. This paper investigated the herding biases by quantifying the self-similarity intensity of cryptocurrency returns' during the COVID-19 pandemic.

[Kinetics, diagnostic and prognostic value of procalcitonin after cardiac surgery].

Cardiac surgery with cardiopulmonary bypass (CPB) can cause a systemic inflammatory response (SIRS) making difficult the interpretation of inflammatory markers. Procalcitonin (PCT) is a marker of inflammation that appears to be a good early marker of infection after cardiac surgery. To study the kinetics of PCT after cardiac surgery with CPB and to determine its diagnostic and prognostic value.

[Increased cardiovascular risk and premature atherosclerosis in rheumatoid arthritis].

Unlabelled: Patients with rheumatoid arthritis (RA) are at increased risk of mortality compared with the general population. Evidence suggests that this increased mortality can largely be attributed to increased cardiovascular (CV) death. In a prospective study, 34 patients with RA were compared with age- and sex-matched controls.

N-terminal pro-brain natriuretic peptide identifies patients at risk for occurence of postoperative atrial fibrillation in cardiac surgery with cardiopulmonary bypass.

Atrial fibrillation (AF) is the most common arrhythmia after cardiac surgery with cardiopulmonary bypass (CPB).The value of N-terminal (Nt)-pro brain natriuretic peptide (BNP) in predicting AF complicating cardiac surgery is not well studied. Our objective is to determine its predictive value in the occurrence of AF after cardiac surgery with CPB.

[Usefulness of magnetic resonance imaging in the diagnosis of early rheumatoid arthritis: a prospective study of 20 cases].

Background: Diagnosing early rheumatoid arthritis is difficult and radiographic signs are often late. MRI detects erosions at an early stage and visualizes synovitis, bone edema and tenosynovitis.

Aim: To assess the value of MRI for diagnosis of early forms of rheumatoid arthritis.

Acute myocardial infarction in a patient with hypofibrinogenemia: a case report.

Introduction: Congenital fibrinogen deficiency is a rare coagulation disorder usually responsible for hemorrhagic diathesis. However, it can be associated with thrombosis and there have been limited reports of arterial thrombotic complications in these patients.

Case Presentation: A 42-year-old Tunisian man with congenital hypofibrinogenemia and no cardiovascular risk factors presented with new onset prolonged angina pectoris.

A delayed diagnosis of lepromatous leprosy: pitfalls and clues to early recognition.

Purpose: To remind special attention to atypical symptoms of Hansen's disease, we report a case of an atypical case due to a delayed diagnosis.

Background: Clinical features of leprosy are well known, cutaneous lesions and involvement of the peripheral nerves being the cardinal clinical signs. Among these presentations, systemic involvement, including mucous membranes of the upper respiratory tract and eyes, is rarely reported even if it is still commonly seen in endemic areas, in particular lepromatous leprosy.

[Rosai-Dorfman disease: therapeutic issues in 2 cases].

Rosai-Dorfman disease (RDD) is a benign lymphoproliferative disorder characterized by cervical lymph node enlargement with a consistent risk of airway compression and esthetic damage. Extranodal localizations are also described. There is no therapeutic consensus for pediatric forms of RDD.

Atherogenic lipid profile in Behçet's disease: evidence of alteration of HDL subclasses.

Background And Aims: Behçet's disease (BD) is an inflammatory vasculitis, most common in the Mediterranean area and Asia. Evidence for accelerated atherosclerosis in BD has been observed. The relationship between cardiovascular risk factors and accelerated atherosclerosis in patients with BD is still controversial.

[Sciatica in a Tunisian teenager: pelvic hydatid cyst].

The purpose of this report is to describe the case of a 13-year-old boy presenting typical sciatica leading to the discovery of primary pelvic hydatid cyst extending to the ischiatic bone. Diagnosis was suspected based on echography and magnetic resonance imaging and confirmed by surgical exploration.

[Rosai -Dorfman disease: a two cases report].

Background: Rosai-Dorfman disease (RDD) is a benign lymphoproliferatif disorder characterized by cervical lymphadenopathies with a consistent risk of airways' compression and esthetical prejudice. Extra nodal localizations are also described.

Aim: To report two pediatric cases of RDD.

Brucellar spondylodiscitis affecting non-contiguous spine levels.

Brucellosis is a zoonosis that affects several organs. The spine is the most common site of musculoskeletal involvement. However, multiple-level spinal involvement is rare in brucella spondylodiscitis.
