As part of the determination of the possible impact of human activities on surface waters, case of Lake Sonfonia, six sampling sites were selected according to their solicitation by the population and their exposure to probable sources of pollution. The objective of this work is to monitor the physico-chemical quality of the waters of Lake Sonfonia during the low water level (March) and during the flood period (August) of the year 2021. Two sampling campaigns of water were carried out in dry weather and two others in cold weather. Parameters such as temperature, pH, EC (Electrical Conductivity), dissolved oxygen, TDS (Total Dissolved Solids) were measured in situ. Suspended matter, phosphate, nitrate, nitrite, sulphates, total iron, COD (Chemical Oxygen Demand) were measured in the laboratory by the colorimetric method. Stata 15 software was applied for the statistical analysis of the data and the correlation test between the parameters gave highly significant correlations. It has been noted that the situation is not very good and that this pollution comes mainly from human activities.

One of the most devastating diseases of rice worldwide is bacterial blight (BLB) caused by Xanthomonas oryzae pv. Oryzae (Xoo). In Benin, Xoo was first described in 2013 on wild rice Oryzae longistaminata. So far, no study has been done on Beninese Xoo strains. We do not know whether the pathogen has already passed into the rice varieties grown, or if they are exposed to other bacteria. Whereas the use of resistant varieties, carrying resistance genes, is the only highly effective and environmentally friendly way to control this disease, no information is available on these Xoo resistance genes in rice varieties grown in Benin apart from the one we recently. This study aims to identify Beninese Xoo strains, causing BLB and screen rice varieties grown in Benin for the main resistance genes. Diseased rice leaves showing typical symptoms of fire blight collected from different rice fields in the three phytogeographic areas of Benin were analyzed by PCR for Xoo-specific sequence identification. Furthermore, seventy-five collected rice accessions were screened to identify xa5, Xa7, xa13, and Xa21 resistance genes to Xoo. The results reveal that Xanthomonas oryzae was identified in two fields in Banikouara and one in Malanville. On the other hand, Sphingomonas sp. has been identified in several other rice fields in Benin. Forty-seven of seventy-five rice accessions examined (62.66%) carried Xoo resistance genes with 3 (4%) and 40 (53.33%) of xa5 and Xa21 respectively. None of the accessions had either Xa7 or xa13 resistance genes. Three accessions possess both xa5 and Xa21 genes. Isogenic lines IRBB60 and IRBB21, supposed to be a positive control, presented a Xoo sensitivity allele. These results indicate that Xoo has moved from the wild rice variety to the cultivated variety in northern Benin and varietal improvement programs must be implemented with varieties having several resistance genes for the efficient response against a possible BLB pandemic in Benin.

Introduction: Fatigue fractures are secondary to excessive, unusual, repeated mechanical stress, occurring on healthy bone. Bone scintigraphy (BS) with 99mTc-HMDP is an excellent means of diagnosis. We report a case of stress fracture of the calcaneus with scintigraphic diagnosis, in a marathon runner. Patient and Methods: He is a 40-year-old athlete in overtraining with right calcaneal pain on running, intense at first, moderate in the middle and then persistent after exercise. The interrogation found no trauma to the right foot and the x-ray of the foot was without abnormality. The so 3 phases were performed following an injection of 564 MBq of 99mTc-HMDP, with a SPECT gamma camera. Results: Bone scintigraphy found in the early phase, hyper-perfusion and hyper-fixation of the right calcaneal region compared to its left counterpart and in the bone phase persistence of focal hyperfixation opposite the right calcaneus. This scintigraphic aspect of the right calcaneus in an overtrained marathon runner, in a painful context and in front of a normal X-ray, made us evoke a fracture of fatigue. A complementary CT scan performed two days after the BS was without abnormality. Conclusion: Fatigue fractures are micro-fractures generally not noticed on radiography and CT. BS due to its high sensitivity is an excellent or the best tool for the early diagnosis of stress fractures.

We report a case of torsion of an ovarian tumor in a 68-year-old woman with no medical and surgical history. The diagnosis was made in front of an intermittently painful pelvic mass. The treatment consisted of a left annexectomy;the anatomopathological examination revealed a fibro-inflammatory and hemorrhagic cyst. Postoperative results were simple with a 12-month follow-up.

AIM:To assess the feasibility of volumetric intensity-modulated arc radiotherapy (VMAT) in patients with limited polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes syndrome. METHODS:A 70-year-old male with histologically confirmed osteosclerotic myeloma was treated in our department in July 2010 with VMAT. Fourty-six Gray in 23 fractions were given on three bone lesions. Doses delivered to target volume and critical organs were compared with a tridimensional conformal radiotherapy (3D-RT) plan. Treatment was well tolerated without any side ***:VMAT improved dose homogeneity within the target volume, as compared to 3D-RT (standard deviations:2.9 Gy and 1.6 Gy for 3D and VMAT, respectively). VMAT resulted in a better sparing of critical organs. Dose delivered to 20% of organ volume (D20) was reduced from 22 Gy (3D-RT) to 15 Gy (VMAT) for small bowel, from 24 Gy (3D-RT) to 17 Gy (VMAT) for bladder and from 47 Gy (3D-RT) to 3 Gy (VMAT) for spinal cord. Volumes of critical organs that received at least 20 Gy (V20) were decreased by the use of VMAT, as compared to 3D-RT (V20 bladder:10% vs 99%; V20 small bowel:6% vs 21%). One year after treatment completion, no tumor progression has been reported. CONCLUSION:VMAT improved dose distribution as compared to 3D-RT for limited osteosclerotic myeloma, with better saving of critical organs.
