High-temperature magma generation process and granulite-facies metamorphism can provide important information about mantle-crustal interaction and tectonic evolution. The strongly peralu- minous monzonite pluton, the Jinshuikou cordierite granite on the southern margin of the Qaidam Block, can provide important information about the mantle-crustal interaction and constraints on tectonic tran- sition from Proto-Tethys to Paleo-Tethys. This pluton develops enclaves of mafic granulite, amphibolite and quartzofeldspathic rocks, and is cut by massive monzonitic leuco-granite veins. Zircon and monazite U-Pb dating for the cordierite granite, the granulite enclaves and a massive monzonitic leuco-granite vein reveal that the cordierite granitic magma was generated from Mesoproterozoic continental crust with protolith derived from a provenanee that was composed of 〉2.8 ga old recycled crustal materials and re- corded a -1.7 ga magmatic event. The continental crust underwent low-pressure granulite-facies metamorphism at -380 Ma ago, whereas the cordierite granite magmas was generated and emplaced during 380 Ma, followed by intrusion of the massive monzonitic leuco-granite vein at circa 370-330 Ma. These data suggest that after the final closure of Proto-Tethys Ocean spreading along the southern Qaidam Block at -420 Ma, break-off of the subducted slab or delamination of the lower crustal ba.e and upwelling of the asthenospheric mantle beneath the southern Qaidam Block occurred before the Mid-Devonian, and that the initiation of the Paleo-Tethys tectonics might initiate near the end of Early-Carboniferous in the East Kunlun-Qaidam region, East Asia.

Cervico-facial cellulitis is a serious poly-microbial infection of the deep fascial spaces of the face and neck which may be life-threatening. The existence of an underlying ground that causes immune failure may promote or complicate this infection. The aim of this work was to describe the socio-demographic and clinical aspects of dental cervicofacial cellulitis associated with HIV in our context. It was a descriptive cross-sectional study that concerned all cases of cervico-facial cellulitis with positive HIV serology encountered at the CHU-CNOS of ba.ako from May 2017 to January 2018. Twenty-four cases were collected. Cellulite with positive HIV accounted for 1.14% of consultations in the service. Females accounted for 67.66% of cases with a sex ratio of 0.5. The average age was 33.58 years old. Housewives accounted for 33.33% of cases. The bride and groom represented 83% of the cases. The triad (pain, swelling, and trismus) was the most common reason for consultation with 41.7% of cases. The tooth 37 was involved in 25% of the cases. In 87% of cases, patients were screened in the service. HIV-1 was found in 75.0% of cases. Complications such as peripheral facial palsy were found in three cases. The medico-surgical treatment was performed in 23 cases with a favorable evolution. The search for an underlying ground, in particular HIV infection, must be systematic in the face of diffuse cervicofacial cellulitis.

ba.kground: Surgical treatment of upper mesocolic organs is improved by preoperative diagnosis of anatomical variants of celiac trunk. According to the literature, these anatomical variants are little known in sub-Saharan Africa. Purpose: To evaluate the prevalence of anatomical variants of celiac trunk in relation to its branching. Materials and methods: This was a cross-sectional study of descriptive type. It retrospectively evaluated 160 abdominal contrast enhanced CT-scan, from patients attending Yalgado OUEDRAOGO teaching hospital, from 1 January 2015 to 30 September 2016. Patients with a history of heavy abdominal surgery were excluded. Images obtained by 64-row CT-scan were analyzed for anatomical variants of the celiac trunk. Results: One hundred and twenty-eight patients (80%) had a classic anatomical configuration of celiac trunk, while thirty-two (20%) had at least one anatomical variant. Two anatomical variants were found in fifteen patients (9.4%) while five other patients (3.1%) had more than two variants. The most frequent anatomical variant was the hepato-splenic bifurcation, found in fourteen patients (8, 8%). It was followed by common celiac and mesenteric trunk, and then collateral arteries, in particular left hepatic artery and right lower diaphragmatic artery, each with three patients (1.9%). Conclusion: Anatomical variants related to celiac trunk branching, are as frequent in our study as in the literature. However, the two most common anatomical variants were hepato-splenic bifurcation and common celiac and mesenteric trunk.

Introduction: Chronic renal failure is a real public health problem because of its prevalence, the cost of its management and the high morbidity and mortality rate associated with it. The objective of this study was to determine the frequency, causes and main aggravating factors of chronic renal failure in the medical department of the hospital of Sikasso. Materials and Methods: This was a cross-sectional, retrospective, descriptive study conducted in the medical department of the Sikasso hospital from January 1, 2021 to November 30, 2022. It covered all the records of patients with chronic renal failure hospitalized in the department during this period. The MDRD formula was used to estimate the glomerular filtration rate. The KDIGO 2012 classification was used to stage CKD. Results: Of 820 patient records reviewed, we retained 197 records. The mean age of our patients was 42.25 ± 10 years. The male sex represented 114 (57.9%). The socio-economic level was considered low and precarious in 79.8% of cases. The frequency of chronic renal failure was 24%. The reason for hospitalization was mostly hyper creatinine > 185 μmol/l (92.4%). Herba. medicine was reported in 103 cases (52.3%). Medical history was hypertension 101 cases (51.3%), undocumented gastro duodenal ulcer (UGD) 14 cases (7.6%), hypertension and diabetes 11 cases (5.1%), diabetes 8 cases (4%), lower limb edema 9 cases (4.6%). Hypocalcemia was 147 cases (75.6%) with hyper phosphoremia was 153 cases (77.7%). Hemoglobin level was: <6 g/dl, 44 cases (22.3%);between 6 - 8 g/dl, 77 cases (39.1%), from 8 - 10 g/dl, 54 cases (27.4%). The etiologies of CKD were vascular nephropathy 106 cases (53.8%), interstitial nephropathy, 44 cases (22.3%), glomerular nephropathy, 33 cases (16.8%), diabetic nephropathy, 12 cases (6.1%) and polycystic kidney disease 2 (1%). CKD was classified as stage 5, 171 cases (86.8%), stage 4, 11 cases (5.6%), stage 3, 13 cases (6.6%) and stage 2, 2 cases (1%.) Dialysis was performed in 1095
