Two different notions of "essential" subsemimodules were introduced in the theory of semimodules over a semiring with identity, in order to generalize the same notion of "essential" submodules in the theory of modules over a ring with identity. In this paper, we introduce a new class of essential subsemimodules called weakly essential subsemimodules. We prove that this new class contains the others two kind of classes of "essential" subsemimodules. Futhermore, we studie the properties of weakly essential subsemimodules. For applications we introduce and investigate the co-hopfian semimodules with this new definition of semi-essential. [ABSTRACT FROM AUTHOR]

Thyroid abscess is a very rare disease due to its anatomical position and the physiology of the gland. It most often occurs in the immunosuppressed population. The diagnosis is easy and is based on ultrasound. However it is often unrecognised. Bacteriological examination allows to identify the germ responsible for this condition. We report the case of a Mauritanian patient living in the said country presenting with painful cervical swelling associated with fever. The diagnosis was based on ultrasound and confirmed by fluid examination. Bacteriological assessment didn't identify the cause of this condition. Patient's outcome was marked by regression of symptoms under antibiotic therapy, with normalization of the gland structure after two months. [ABSTRACT FROM AUTHOR]

Introduction: this study aims to determine the clinical and evolutionary profile of skin and soft tissue lesions in diabetics followed up at the dressing room. Methods: we conducted an observational descriptive and analytical study in the dressing room of the Marc Sankalé Diabetes Center, Dakar from 1 January to 31 December 2017. Our study focused on diabetics who were examined in the dressing room. Results: a total of 37.173 procedures were recorded at the Marc Sankalé Diabetes Center; 16.418 patients were treated in the dressing room, representing a prevalence of 14.16%. The average age of patients was 56,6 ±12 years, the sex ratio (M/F) was 0,88. Type 2 diabetes predominated (78,97%) and the average disease duration was 8.06 ± 7.9 years. The mean capillary blood glucose concentration was 2.4±1 g/l. Diabetic neuropathy was found in 72.33% of patients. Limb lesions were found in 93,98% of patients(1185 cases). The most common lesions included: ulcer (46,76%), abscess (13.46%), phlegmon (13.20%), gangrene (8.41%), erysipelas (3.78%), perforating ulcer (3.53%), intertrigo (3.95%). The lesions were be divided into infectious lesions (61,41), non-infectious lesions(33,50%), pure vascular lesions (1.57%) and mixed lesions (3.70%). Out of 1189 patients 7.57% had had osteitis. The germs found were Gram-positive bacteria (12.70%), Gram-negative bacteria (23.80%). Amputation was performed according to the topographical features of the lesion (p=0.00), the type of lesion (p=0.000), the seniority of diabetes (p=0.02), the type of diabetes (p=0.008), the presence of osteitis (p=0.006). Minor amputation was performed in 43,33% of cases, major amputation in 37.43% of cases; 70 deaths were recorded (5.89%). Conclusion: skin and soft tissue lesions were dominated by diabetic foot. Mortality is not negligible and the risk of amputation was statistically related to the topographical features of the lesion, the type of lesion, the seniority and the type of diabetes and the presence of osteitis.
