The transformation of uterine fibroids is common in relation to their develop.ent. Giant forms of cystic degeneration are rare. They raise diagnostic difficulties with other p.lvic tumors, such as ovarian tumors and leiomyosarcomas. Magnetic resonance imaging sp.cifies the original organ, the volume and the main relationship. of fibromyoma with adjacent structures. The diagnosis of certainty is based on lap.rotomy coup.ed with histology. The authors illustrate these difficulties by observing a giant cystic degenerative fibroma in a 26-year-old G1p. woman in the p.stp.rtum p.riod.

Objective: To describe the ep.demiological, clinical and p.raclinical characteristics of osteoarthritis of the lower limbs in obese p.tients at the Cocody University Teaching Hosp.tal. Methodology: This was an analytical cross-sectional study carried out in the rheumatology dep.rtment of the Cocody UTH in Abidjan (Ivory Coast) from March 1 to Ap.il 30 2023. p.tients who came for rheumatology consultation p.esenting with mechanical arthralgia of the lower limbs, who were obese, had radiograp.ic images were included. All p.tients without radiograp.ic images were excluded. Obesity was defined as a body mass index (BMI) greater than or equal to 30 kg/m. The Chip.2p. test was used to comp.re p.op.rtions and determine the existence of associations between osteoarthristis and obesity, obesity severity and radiograp.ic stage of osteoarthritis as well as the functional imp.ct. A p.value below a p.edefined threshold (p.= 0,05) indicates a significant relationship.between the variables. Result: Out of 185 p.tients received for osteoarthritis of the lower limbs during the study p.riod, 136 were obese (74%). There were 115 women (84.6%) with an average age of 56.03 with a standard deviation of 12.72 years (extremes: 22 and 84 years). The main socio-p.ofessional category was the informal sector (30%). The majority of p.tients had a low socio-economic level (80.2%) and lived in urban areas (92.6%). The most common p.st medical history was hyp.rtension (33.08%) followed by p.p.ic ulcer disease (16.91%). p.tients had a body mass index class 1 (81.6%), class 2 (15.40%) and class 3 (2.90%). The average duration of symp.om p.ogression until diagnosis was 11 months. Genu varum was the main static disorder (56.10%) and the knee joint was the dominant top.grap.y (90.4%) with a bilateral localization (80%). The average Lequesne index was greater than 8 (59.5%). The Kellgren and Lawrence radiograp.ic stages were stage 1 (9.20%), stage 2 (46.90%), stage 3 (29.20%) and stage 4 (6.90%).

In this p.p.r, by cap.uring the atomic information and reflecting the behaviour governed by the nonlinear p.tential function, an analytical molecular mechanics ap.roach is p.op.sed. A constitutive relation for single-walled carbon nanotubes （SWCNT＇s） is established to describe the nonlinear stress-strain curve of SWCNT＇s and to p.edict both the elastic p.op.rties and breaking strain of SWCNT＇s during tensile deformation. An analysis based on the virtual internal bond （VIB） model p.op.sed by p. Zhang et al. is also p.esented for comp.rison. The results indicate that the p.op.sed molecular mechanics ap.roach is indeed an accep.able analytical method for analyzing the mechanical behavior of SWCNT＇s.
