Ostéchondromatose synoviale de l’articulation carpo-métacarpienne du pouce chez une patiente atteinte d’un lupus érythémateux systémique

L'ostéchondromatose synoviale est une métaplasie du tissu synovial. Elle engendre de petites masses  cartilagineuses qui font saillie à la face interne de la synoviale, puis, se pédiculisent et enfin s'en détachent en développant des chondromes libres. On en distingue deux formes d'ostéchondromatose , la forme primitive, qui est rare, et la forme secondaire plus fréquente dont l'origine est généralement l'arthrose. Nous rapportons un cas d'ostéchondromatose synoviale de l'articulation carpo-métacarpienne du pouce chez une patiente  atteinte d'un lupus érythémateux systémique.Key words: Ostéochondromatose, lupus, arthros

Nous avons étudié les caractéristiques de la DM du sujet âgé à travers une étude rétrospective dans laquelle nous avons comparé 4 patients âgés de plus de 65 ans au début de la myosite avec 40 sujets jeunes.Pan African Medical Journal 2012; 13:2

ANTIDIABETIC ACTIVITY OF CAFFEIC ACID AND 18Î’-GLYCYRRHETINIC ACID AND ITS RELATIONSHIP WITH THE ANTIOXIDANT PROPERTY

Objective: This study was performed to investigate the antidiabetic effect of caffeic acid and 18 β -glycyrrhetinic acid against diabetic rats.Methods: In this experiment, the animals were divided into five groups. Group I: Normal rats. Group II: diabetic control rats.Group III: diabetic rats treated with 18β-glycyrrhetinic. Group IV: diabetic rats treated with caffeic acid. Group V: diabetic rats treated with 18β-glycyrrhetinic and caffeic acid. Fasting blood glucose, insulin, glutathione reductase (GR), glutathione peroxidase (GPx), total antioxidant (TAO), catalase , and superoxide dismutase (SOD) and malondialdehyde (MDA) were analyzed.Results: Fasting blood glucose and MDA were significantly increased, whereas insuline, GR, GPx, TAO, catalase , SOD were decreased significantly in diabetic rats. Though the diabetic rats treated with caffeic acid and 18β-glycyrrhetinic acid individual exerts beneficial effects in all the biochemical parameters in diabetic rats. The combined treatment with caffeic acid and 18β-glycyrrhetinic acid normalized all the above-mentioned biochemical parameters in diabetic rats.Conclusion: our findings demonstrated that 18β-glycyrrhetinic acid and  caffeic acid either used individually or in combination to diabetic rats have an antidiabetic effect and a good antioxidant property .From the results, the combined dose of 18β-glycyrrhetinic acid and caffeic acid to diabetic rats showed promising antidiabetic effect and antioxidant property compared to individual treatments.Keywords: Diabetes, Caffeic acid, 18β-glycyrrhetinic acid, Streptozotocin, Antioxidant

La périartérite noueuse : un diagnostic à ne pas méconnaitre! : Polyarteritis nodosa: a diagnosis not to be ignored!

Polyarteritis nodosa (PAN) is a systemic necrotizing vasculitis, which typically affects medium-sized muscular arteries. With the decline of hepatitis B virus (HBV) and the evolving definitions of vasculitis, PAN is becoming a rare disease. It's certainly become a rare disease, but it still exists. It has its own clinical and laboratory characteristics. A well-chosen treatment adapted to the severity of the disease allows an improvement in symptoms. We report 3 cases of PAN with different clinical presentations. La périartérite noueuse est une vascularite systémique touchant des artères de petit et moyen calibre . C’est une maladie certes devenue rare, mais elle est bien individualisée des autres vascularites systémiques. Elle reste un diagnostic à ne pas méconnaitre devant un tableau systémique. Elle possède des caractéristiques cliniques et paracliniques bien distinctes. Un traitement bien choisi adapté à la sévérité de la maladie permet une amélioration de la symptomatologie. Les auteurs Nous rapportent cependant, 3 cas de PAN avec des présentations cliniques différentes

Bioactive Metabolites from Propolis Inhibit Superoxide Anion Radical, Acetylcholinesterase and Phosphodiesterase (PDE4)

Cycloartane-triterpenes (cycloartenol, 3α-cycloartenol-26-oic acid and 3β-cycloartenol-26-oic acid) together with α-amyrin acetate and flavonoids (pinostrobin, tectochrysin and chrysin) were isolated from Egyptian propolis for the first time. Their antioxidant activity was evaluated with DPPH and superoxide anion radical (O2.-). All compounds possessed both (O2.-) scavenging as well as XOD inhibitory activity in the range of 50 – 75 %. With DPPH, only the flavonoids showed scavenging activity (48 – 83 %). Acetylcholinesterase (AChE) and phosphodiesterase type 4 (PDE4) inhibitors are currently considered as intracellular targets for treatment of Alzheimer’s disease and Chronic obstructive pulmonary disease (COPD). 3β-cycloartenol-26-oic acid moderately inhibited AChE and PDE4 activities in vitro with IC50 values of 0.8±0.2 and 1.9±0.4 μM, respectively, while 3-cycloartenol-26-oic acid inhibited AChE activity with an IC50 value of 2.1±0.1 μM. The flavonoids pinostrobin and chrysin reduced PDE4 activity by 43 and 40 %, respectively (10 μM) as well as moderately inhibited the growth of the HepG2 cell line, whereas chrysin reduced proliferation of NIH-3T3 cells at 50 μM. Therefore, our results with 3β- and 3-cycloartenol-26-oic acids can contribute to further research on alternative drugs for the treatment of neurological and neurodegenerative diseases, as well as asthma and COPD

Parents’ Acceptance to Alveolar and Nasoalveolar Molding Appliances during Early Cleft Lip and Palate Care: A Call for High-Quality Research

AIM: Acceptance and compliance of the parents are an essential pillar in the success of pre-surgical infant orthopedic (PSIO) treatment. The aim of this systematic review is to evaluate the burden of care associated with the alveolar molding (AM) and nasoalveolar molding (NAM) appliances as experienced by the parents with unilateral complete cleft lip and palate (UCLP) infants. METHODS: An electronic search was carried on by two reviewers in eight search engines, as well as a manual search till July 2019. Randomized controlled trials (RCTs) comparing AM/NAM appliances to controls in infants with UCLP were selected. Risk of bias was evaluated using Cochrane risk of bias assessment tool for RCTs. RESULTS: One RCT was included in the qualitative analysis. Non-significant differences were found in the amount of mothers’ satisfaction between the intervention and control groups. CONCLUSIONS: Insufficient low-quality evidence is available regarding the effects of AM and NAM on parents’ satisfaction and burden of care. No conclusions can be withdrawn from the existing studies. High-quality research is needed to elucidate the degree of parents’ acceptance to the molding appliances. PROSPERO registration number: CRD42016043174

Workaholism, sleep disorders, and potential e-learning impacts among Menoufia university staff during COVID–19 pandemic

Background: Workaholism is described as a constant, internal drive to work and behavioral addiction to work. Studies have shown the negative associations between workaholism, job performance, and health results as disrupted sleep. The purpose of this research was to compare the prevalence of workaholics among the academic staff of practical and theoretical Faculties in Egyptian universities using the Dutch Workaholism Scale (DUWAS) and to determine associated sleep problems. Also, it studied the added impact of E-learning on the prevalence of workaholism frequency during the COVID-19 pandemic. Design and Methods: A cross-sectional study was conducted among 336 participants. Work addiction was assessed using DUWAS (17 items) as well as questionnaires on personal, occupational characteristics, and sleep problems. DUWAS scale was repeated after six months during COVID 19 pandemic to investigate the impact of E-learning on the workaholic behavior of the studied groups. Results: Our study revealed that the prevalence of workaholism was 33 percent. 32.8% and 33.7% were listed for the faculties of Medicine and Arts, respectively. After the COVID-19 pandemic, workaholic frequency was significantly increased to be 46.4%. Adjusted logistic regression analysis showed that workaholism had negatively impacted sleep in terms of difficulty initiating sleep, difficulty maintaining sleep, and insufficient sleep. Conclusion: The prevalence of workaholism appears to be high among university staff members especially after COVID-19 crisis. Sleep problems were linked to workaholics more than other workers. We recommend encouraging employees to work to their contracted hours, as excess work over extended periods may have adverse effects not only on organizational productivity but also on their health

Transverse Skeletal Effects of Rapid Maxillary Expansion in Pre and Post Pubertal Subjects: A Systematic Review: A Systematic Review.

OBJECTIVE: The aim of this systematic review was to assess the transverse skeletal effects of rapid maxillary expansion (RME) in pre and post-pubertal subjects. MATERIAL AND METHODS: Five databases were searched till May 2018; Pubmed, Cochrane, Scopus, Lilacs and Web of science in addition to the manual search of other sources. There were no language restrictions. Methodological Index for Non-Randomized Studies MINORS was used to assess the quality and risk of bias of the trials included. RESULTS: Six studies were finally included in the qualitative analysis. A meta-analysis wasn’t performed due to the heterogeneity of methodologies and outcomes. All of the included studies showed drawbacks in their structure yielding weak evidence. On the short term, RME caused an increase in the maxillary and lateral-nasal widths in pre-pubertal subjects by 3.4 mm and 3.3 mm, and by 2.8 and 2.2 mm respectively in post-pubertal subjects. Although statistically insignificant, the maxillary width increase was more than that of the post-pubertal subjects by 0.6 mm. Over the long term, expansion produced permanent increases in the transverse dimensions of both the dento-alveolar and skeletal components of the maxilla and circum-maxillary structures in pre-pubertal subjects. The post-pubertal subjects presented with a statistically significant increase only in the later-nasal width by 1.3 mm than the untreated controls with no permanent increase in the skeletal maxillary width. CONCLUSION: The literature is very deficient regarding the use of skeletal age as a reference in the treatment of skeletal crossbites using RME. Only weak evidence exists supporting the increased maxillary and lateral-nasal widths after tooth-tissue borne RME in pre-pubertal subjects, with these effects being less in the post-pubertal ones
