Septic arthritis is an infectious disease that commonly affects weight-bearing or proximal joints such as the knee and the hip. The sternoclavicular joint is an unusual site of this entity. It usually occurs in patients with diabetes mellitus, intravenous drug abusers, or those with rheumatoid arthritis. Analysis of the previous literature showed few articles and these described essentially cases of unilateral presentation. Case presentation: We report a rare case of a bilateral septicdoi:10.1186/s13256-018-1709-9 pmid:29973288 pmcid:PMC6033282 fatcat:lvfywxxmwzglbaac4ea7gbopsq

Imaging investigations revealed destruction of the medial extremities of her two clavicles and bilateral collections in the soft tissues around her sternoclavicular joints. She was treated successfully by needle aspiration drainage combined with a 12-week antibiotherapy. Conclusions: Bilateral septic arthritis of the sternoclavicular joint is an extremely rare entity, with a paucity of literature. Only early diagnosis, which is obtained from the culture of the joint fluid using needle aspiration, allows satisfactory functional outcome and a good prognosis. Osteoarticular infections should be considered in patients with recent infective endocarditis in cases of fever recurrence.
The implication of organic acids in Cd and Ni translocation was studied in the halophyte species Sesuvium portulacastrum. Citric, fumaric, malic, and ascorbic acids were separated and quantified by HPLC technique in shoots, roots and xylem saps of plants grown on nutrient solutions added with 50 µM Cd, 100 µM Ni and the combination of 50 µM Cd + 100 µM Ni. Results showed that Cd had no significant impact on biomass production while Ni and the combination of both metals drastically affecteddoi:10.3389/fpls.2015.00156 pmid:25821455 pmcid:PMC4358066 fatcat:3utnf3tcv5g53htgontyelfwu4

Cadmium and Ni concentrations in tissues and xylem sap were higher in plants subjected to individual metal application than those subjected to the combined effect of Cd and Ni suggesting a possible competition between these metals for absorption. Both metals applied separately or in combination induced an increase in citrate concentration in shoots and xylem sap but a decrease of this concentration in the roots. However, a minor relationship was observed between metal application and fumaric, malic, and ascorbic acids. Both observations suggest the implication of citric acid in Cd, Ni translocation and shoot accumulation in S. portulacastrum. The relatively high accumulation of citric acid in xylem sap and shoot of S. portulacastrum could be involved in metal chelation and thus contributes to heavy metal tolerance in this species.
Genetic polymorphisms in DNA repair genes might influence the repair activities of the enzymes predisposing individuals to cancer risk. Owing to the presence of these genetic variants, interethnic differences in DNA repair capacity have been observed in various populations. The present study was undertaken to determine the allele and genotype frequencies of two common non-synony- ) in a healthy Tunisian population and to compare them with HapMap (http://www.hapmap.org/) populations.

Our findings showed a close relatedness with Caucasians from European ancestry which might be explained by the strategic geographic location of Tunisia in the Mediterranean, thus allowing exchanges with Europeans countries. The in silico predictions showed that p.Thr241[Met substitution in XRCC3 protein was predicted as possibly damaging, indicating that it is likely to have functional consequences as well. To the best of our knowledge, this is the first study in this regard in Tunisia. So, these data could provide baseline database and help us to explore the relationship of XRCC3 and XPD polymorphisms with both cancer risk and DNA repair variability in our population.
Congenital adrenal hyperplasia (CAH) describes a group of inherited autosomal recessive disorders characterized by enzyme defects in the steroidogenic pathways that lead to the biosynthesis of cortisol, aldosterone, and androgens. Chronic excessive adrenocorticotropic hormone (ACTH) stimulation may result in hyperplasia of ACTH-sensitive tissues in adrenal glands and other sites such as the testes, causing testicular masses known as testicular adrenal rest tumors (TARTs). Leydig cell tumorsdoi:10.1155/2012/648643 pmid:22606635 pmcid:PMC3350130 fatcat:zbfdqr2nbvbsdnkhe2l4ozzrje

This distinction is interesting because LCTs and TARTs require different therapeutic approaches. Hereby, we present an unusual case of a 19-year-old patient with CAH due to 11β-hydroxylase deficiency, who presented with TARTs and an epididymal Leydig cell tumor.
Plants are an important source of pharmacologically active compounds. In the present work, we characterize the impact of black cumin (Nigella sativa L.) aqueous extracts on a yeast model of p53-dependent apoptosis. To this end, the Saccharomyces cerevisiae recombinant strain over-expressing p53 was used. The over-expression of p53 triggers the expression of apoptotic markers: the externalization of phosphatidylserine, mitochondrial defect associated with cytochrome-c release and the inductiondoi:10.3390/cells11050869 pmid:35269491 pmcid:PMC8909299 fatcat:jchc4kcs4vgslguuqksgugziea

Thus, we focus on the anti-apoptotic molecules present in the aqueous extract of Nigella sativa L. These extracts were purified and characterized by complementary chromatographic methods. Specific fluorescent probes were used to determine the effect of the extracts on yeast apoptosis. Yeast cells over-expressing p53 decrease in relative size and have lower mitochondrial content. The decrease in cell size was proportional to the decrease in mitochondrial content and of mitochondrial membrane potential (ΔΨm). These effects were prevented by the purified aqueous fraction obtained by fractionation with different columns, named C4 fraction. Yeast cell death was also characterized by reactive oxygen species (ROS) overproduction. In the presence of the C4 fraction, ROS overproduction was strongly reduced. We also noted that the C4 fraction promotes the cell growth of control yeast cells, which do not express p53, supporting the fact that this purified extract acts on cellular mediators activating cell proliferation independently of p53. Altogether, our data obtained on yeast cells over-expressing p53 demonstrate that anti-apoptotic molecules targeting p53-induced apoptosis associated with mitochondrial dysfunction and ROS overproduction are present in the aqueous extracts of Nigella seeds and in the purified aqueous C4 fraction.

Hypertension is the leading cause of morbi-mortality in our country. Thus, we conducted this national survey on hypertension to analyze the profile of the Tunisian hypertensive patient and to assess the level of blood pressure control. Nature HTN is an observational multicentric survey, including hypertensive individuals and consulting their doctors during the period of the study. Blood pressure measurements were conducted during consultation, using a standardized auscultatory or oscillometricdoi:10.1186/s12872-022-02584-y pmid:35351007 pmcid:PMC8966189 fatcat:edovesbjzfdvvi67su2ybadgxe

The primary endpoint of our study was uncontrolled hypertension defined by a systolic blood pressure ≥ 140 mmHg and/or diastolic blood pressure ≥ 90 mmHg. Three hundred twenty-one investigators participated in the study. We enrolled 25,890 patients with a female predominance (Sex ratio, 1.21) and an average age of 64.4 ± 12.2 years. Most individuals were treated in the public sector (74%), 39.4% of patients were diabetic, 25.8% were obese, 44.6% were overweight and 14% were smokers. Hypertension was controlled in 51.7% of cases if we consider 140/90 as a BP target, and only in 18.6% if we consider 130/80 as a target. The independent predictors of uncontrolled blood pressure were male sex (OR = 1.09, 95%CI [1.02-1.16]), age > 65 year-old (OR = 1.07, 95% CI[1.01-1.13], diabetes (OR = 1.18, 95% CI [1.11-1.25], Smoking (OR = 1.15, 95% CI [1.05-1.25]), Obesity (OR = 1.14, 95% CI[1.07-1.21]), management in public sector (OR = 1.25, 95% CI [1.16-1.34]), and Heart rate > 80 bpm (OR = 1.59, 95% CI [1.48-1.71]). Contrarily, high educational level (OR = 0.9, 95% CI [0.84-0.97], absence of history of coronary disease (OR = 0.86, 95% CI [0.8-0.93]), salt restriction (OR = 0.48, 95% CI [0.45-0.51]), drug compliance (OR = 0.57, 95% CI[0.52-0.61]), and regular physical activity (OR = 0.77, 95% CI[0.71-0.84]) are strong predictors of blood pressure control. NaTuRe HTN showed that blood pressure control was reached in more than half of the Tunisian people. The control remains low in patients with high cardiovascular profiles and in those treated in the public sector. A national health program based on therapeutic education, regular control and continuous support to the public institutions is needed to decrease the burden of hypertension incidence rate.
