Inborn Errors of Immunity in Algerian Children and Adults: A Single-Center Experience Over a Period of 13 Years (2008-2021).

Background: Inborn errors of immunity (IEI) predispose patients to various infectious and non-infectious complications. Thanks to the development and expanding use of flow cytometry and increased awareness, the diagnostic rate of IEI has markedly increased in Algeria the last decade.

Aim: This study aimed to describe a large cohort of Algerian patients with probable IEI and to determine their clinical characteristics and outcomes.

Numerical solution of fractional boundary value problem with caputo-fabrizio and its fractional integral.

In this article, we investigate the existence and uniqueness of the solution of a fractional boundary value problem with conformable fractional derivation of the Caputo-Fabrizio type. In order to study this problem we used a new definition of fractional integral as an inverse of the conformable fractional derivative of Caputo-Fabrizio, therefore, so we transformed the problem to a equivalent linear Volterra-Fredholm integral equations of the second kind, and taking sufficient conditions existence and uniqueness of this solution is proven based on the results obtained. The analytical study is followed by a complete numerical study.

Genomic basis of syndromic short stature in an Algerian patient cohort.

Short stature is one of the most common reasons for a referral to the pediatric endocrinology clinic. Thousands of patients with short stature are assessed annually at the Department of Endocrine and Metabolic Diseases (DEMD) at Bab el Oued University Hospital in Algiers, Algeria. However, diagnostic rates in patients with syndromic short stature are not optimal due to the unavailability of next generation sequencing (NGS) technology.

Amberlite IRC-718 ion chelating resin extraction of hazardous metal Cr (VI) from aqueous solutions: equilibrium and theoretical modeling.

Under varied conditions, the IRC 718 ion-exchange resin is used to extract chromium (VI) ions from aqueous solutions. On chromium (VI) removal effectiveness, the effects of adsorption dosage, contact time, beginning metal concentration, and pH were examined. The batch ion exchange process reached equilibrium after around 90 minutes of interaction.

Diagnostic and Predictive Contribution of Autoantibodies Screening in a Large Series of Patients With Primary Immunodeficiencies.

Objectives: To evaluate the diagnostic and predictive contribution of autoantibodies screening in patients with primary immunodeficiencies (PIDs).

Methods: In the present study, PID patients and healthy controls have been screened for 54 different autoantibodies. The results of autoantibodies screening in PID patients were correlated to the presence of autoimmune diseases.

Clinical lessons learned in constitutional hypopituitarism from two decades of experience in a large international cohort.

Context: The international GENHYPOPIT network collects phenotypical data and screens genetic causes of non-acquired hypopituitarism.

Aims: To describe main phenotype patterns and their evolution through life.

Design: Patients were screened according to their phenotype for coding sequence variations in 8 genes: HESX1, LHX3, LHX4, PROP1, POU1F1, TBX19, OTX2 and PROKR2.

Breastfeeding for Primary Prevention of Stroke.

A recent review by Zhang et al. published in the "Journal of the National Medical Association" focused on the major and emerging strategies for the prevention of stroke. We would highlight the evolving role of breastfeeding as an efficient intervention in primary prevention of such cardiovascular disease, including in black women.

Thyroid Cancer and Iodine Deficiency Status: A 10-Year Review at a Single Cancer Center in Tanzania.

Objective: To highlight the magnitude and distribution of thyroid cancer at the largest cancer center in Tanzania and to correlate patient region of residence with regions of dietary iodine adequacy and deficiency in the country.

Study Design: A retrospective cross-sectional chart review to characterize patients with thyroid cancer and regions of residence.

Setting: Ocean Road Cancer Institute (ORCI), the largest cancer center in Tanzania.

Chemical composition, antioxidant, anticholinesterase, antimicrobial and antibiofilm activities of essential oil and methanolic extract of Anthemis stiparum subsp. sabulicola (Pomel) Oberpr.

Anthemis species are traditionally used to treat infectious and inflammatory processes, among others clinical disturbances. In the current study, the chemical composition, the total phenolic and flavonoid contents, the antioxidant, anticholinesterase, antimicrobial, and antibiofilm activities of Anthemis stiparum subsp. sabulicola aerial parts methanolic extract (As-ME) and essential oil (As-EO) were investigated.

NNT mutations: a cause of primary adrenal insufficiency, oxidative stress and extra-adrenal defects.

Objective: Nicotinamide nucleotide transhydrogenase (NNT), one of the several genes recently discovered in familial glucocorticoid deficiencies (FGD), is involved in reactive oxygen species detoxification, suggesting that extra-adrenal manifestations may occur, due to the sensitivity to oxidative stress of other organs rich in mitochondria. Here, we sought to identify NNT mutations in a large cohort of patients with primary congenital adrenal insufficiency without molecular etiology and evaluate the degree of adrenal insufficiency and onset of extra-adrenal damages.

Methods: Sanger or massive parallel sequencing of NNT and patient monitoring.

Chemical constituents of essential oil of endemic Rhanterium suaveolens Desf. growing in Algerian Sahara with antibiofilm, antioxidant and anticholinesterase activities.

Twenty compounds were detected in the essential oil of Rhanterium suaveolens representing 98.01% of the total oil content. Perillaldehyde (45.

Trace elements profile is associated with insulin resistance syndrome and oxidative damage in thyroid disorders: Manganese and selenium interest in Algerian participants with dysthyroidism.

The relationship between dysthyroidism and antioxidant trace elements (ATE) status is very subtle during oxidative stress (OS). This relationship is mediated by thyroid hormone (TH) disorder, insulin resistance syndrome (IRS) and inflammation. The aim of this study was to investigate ATE such as selenium (Se), manganese (Mn), zinc (Zn) and copper (Cu) status on thyroid dysfunction, and their interaction with antioxidant enzyme activities, mainly, superoxide dismutase (SOD) and glutathione peroxidase (GPx), TH profile (TSH, T(3), T(4)) and IRS clusters.

Spontaneous resolution of pituitary apoplexy in a giant boy under 10 years old.

Aim: Pituitary gigantism is a very rare condition; the occurrence of pituitary apoplexy in children younger than 10 years old is even rarer. The aim of our study is to report this exceptional association.

Observation: A boy aged 9 years and 6 months was hospitalized for the first time in November 2011 for symptoms suggesting pituitary apoplexy.

Congenital craniopharyngioma: a case report and literature review.

Introduction: Although craniopharyngiomas are congenital tumors, they are rarely diagnosed in the prenatal or early neonatal period. Sometimes they are very large, debilitating and life-threatening, as in the case discussed here.

Observation: A 21-month-old girl was referred for craniopharyngioma that had been diagnosed at 5 months because of neurologic complications.
