Indigenous microalgae strains characterization for a sustainable biodiesel production.

Microalgae have been widely recognized as a promising feedstock for sustainable biofuels production to tackle global warming and pollution issues related to fossil fuels uses. This study identified and analyzed indigenous microalgae strains for biodiesel production, specifically Chlorella vulgaris and Coelastrella thermophila var. globulina, from two distinct locations in Algeria.

Characteristics of DRESS Syndrome in the Elderly: A Comparative Study of 55 Patients.

Drug reaction with eosinophilia and systemic symptoms (DRESS) is a rare drug reaction characterized by a skin rash, eosinophilia, and organ involvement. Our purpose is to focus on the clinical and epidemiological characteristics of DRESS in the elderly and to identify the incriminated drugs. This is a retrospective study including patients, hospitalized for DRESS with a RegiSCAR ≥4.

An unusual pigmented skin lesion on the nipple-areola area.

Considering the rarity and underdiagnoses of this disorder, a pigmented and hyperkeratotic skin lesion located on the trunk, resembling to acanthosis nigricans should always be investigated for terra firma-forme dermatosis (TFFD) and thus alcohol must be applied. TFFD should be known among dermatologists and can be easily diagnosed and treated with isopropyl alcohol.

Unusual malar rash with ulceration: What can we expect?

Considering the clinical polymorphism of the disease, longstanding skin lesions located on the face, resembling erysipelas in an endemic area should always be investigated for CL and thus, atypical presentations should be kept in mind.

Gingival Recession: An Unusual Oral Presentation of Morphea "en coup de sabre".

A 21-year-old woman presented with a 13-year history of a linear lesion on the lip. She experienced no pain and only had an esthetic complaint. Her personal and family history was otherwise unremarkable.

Acral blisters in neonates: Three rare and benign diseases.

Exclusive acral involvement in neonatal pemphigus is unusual. Blisters in neonatal bullous pemphigoid, affecting 2%-3% of newborns of mothers with gestational pemphigoid, can be located in the trunk, limbs and acral areas. Unlike neonatal bullous pemphigoid, which can appear up to 5 days after birth, neonatal pemphigus is often revealed at birth.

Comparative Assessment of Nitrogen Concentration Effect on Microalgal Growth and Biochemical Characteristics of Two Strains Cultivated in Digestate.

Microalgae have been recently recognized as a promising alternative for the effective treatment of anaerobic digestion effluents. However, to date, a widely applied microalgae-based process is still absent, due to several constraints mainly attributed to high ammonia concentrations and turbidity, both hindering microalgal growth. Within this scope, the purpose of the present study was to investigate the performance of two strains, SAG 211-11b and a local Algerian isolate, under different nitrogen levels, upon ammonia stripping.

A verrucous tumor of the leg: Atypical case of Syringocystadenoma Papilliferum.

Syringocystadenoma Papilliferum (SCAP) is a benign adnexal tumor. Most of the cases present with a solitary lesion in the head and neck region at birth or in early childhood. In fact, only two cases of SCAP on the lower leg have been reported in the literature.

Multiple nodules in the scrotal wall.

Herein, we report a rare case of extensive ISC. It affects dark-colored skin men aged from 20 to 40 years old, suggesting an ethnic susceptibility. Pathogenesis of scrotal calcinosis remains controversial.

A case of a verrucous and pseudotumoral mass on the leg that resolved with cryotherapy.

Various clinical forms of cutaneous leishmaniasis can be encountered such as: ulcerated, lupoïd, sporotrichoïd and other rare forms (eczematiform, erysipeloid, psoriasiform, verrucous, and pseudotumoral). We report an atypical presentation of verrucous and pseudotumoral cutaneous leishmaniasis that resolved following a course of cryotherapy.

[A rare cause of AA amyloidosis: Hereditary epidermolysis bullosa].

Introduction: Recessive dystrophic epidermolysis bullosa is a rare genetic condition characterized by fragile skin and mucous membrane, caused by mutations in the COL7A1 gene. AA amyloidosis is a rare complication of these genodermatosis.

Observations: Two patients with recessive dystrophic epidermolysis bullosa, generalized severe in the first case and generalized intermediate in the second case, developed at the age of 38 and 28, respectively, nephrotic syndrome.

Hydroxychloroquine-induced acute generalized exanthematous pustulosis: a series of seven patients and review of the literature.

Background: Hydroxychloroquine (HCQ)-induced acute generalized exanthematous pustulosis (AGEP) is poorly described in the literature. The aim of our study was to characterize the clinical, laboratory, allergological, and genetic features of HCQ-induced AGEP.

Methods: We conducted a retrospective study of patients with HCQ-induced AGEP diagnosed between 2011 and 2019.
