Introduction: Hypertensive emergencies are a reality in the cardiology department of the Ignace Deen National Hospital. The aim of this study was to determine the clinical, therapeutic and evolutionary profile of hypertensive emergencies in the cardiology department of the Ignace Deen National Hospital. Methods: This was a longitudinal descriptive study of patients admitted to the cardiology department of the Ignace Deen National Hospital for hypertensive emergencies, over a period of six (6) months from 1 October 2020 to 31 March 2021. Results: Among the 638 patients admitted to the cardiology department during the study period, 102 cases of hypertensive emergencies were identified, representing a frequency of 15.99%. The mean age of the patients was 56.65 ± 13.33 years, with extremes of 23 and 90 years, and the sex ratio was 1.91 in favour of men. The associated cardiovascular risk factors were: age (76.47%), smoking (41.18%), sedentary lifestyle (31.37%), obesity (16.67%), dyslipidaemia (12.75%), diabetes (11.76%) and excessive alcohol consumption (11.76%). The various clinical pictures found were: acute pulmonary oedema 39 cases (38.23%), acute coronary syndrome 31 cases (30.39%), stroke 17 cases (16.67%), hypertensive encephalopathy 11 cases (10.78%), acute renal failure 3 cases (2.94%) and aortic dissection 1 case (0.98%). The drugs used on admission were calcium antagonists (Nicardipine 10mg) in 58 cases (56.86%), diuretics (Furosemide 20mg) in 44 cases (43.13%), nitrates (Risordan 20mg) in 39 cases (38.23%) and beta-blockers in 31 cases (30.39%). In terms of outcome, 88 (86.27%) patients had improved. However, 12 (11.76%) deaths were recorded. Conclusion: Hypertensive emergencies are a worrying condition with a high prevalence in the cardiology department of the Ignace Deen National Hospital.

Statistical Study of the Geoeffectivity of Halo Coronal Mass Ejections Associated with X-Class Flares during Solar Cycles 23 and 24

引用

Open Journal of Applied Sciences 2024年第4期14卷 950-960页

作者： Younoussa diakite Christian Zoundi M’Bi Kabore Jean Louis Zerbo Laboratoire de Chimie Analytique de Physique Spatiale et Energ&#233tique (L@CAPSE) Physics Department Universit&#233 Norbert Zongo Koudougou Burkina Faso Laboratoire de Maté riaux d&#8217H&#233liophysique et Environnement (LAMHE) Physics Department Universit&#233 Nazi Boni Bobo-Dioulasso Burkina Faso

By analysing a long series of data (1996-2019), we show that solar cycle 23 was more marked by violent solar flares and coronal mass ejections (CMEs) compared to solar cycle 24. In particular, the halo coronal mass ejections associated with X-class flares appear to be among the most energetic events in solar activity given the size of the flares, the speed of the CMEs and the intense geomagnetic storms they produce. Out of eighty-six (86) X-class halo CMEs, thirty-seven (37) or 43% are highly geoeffective;twenty-four (24) or approximately 28% are moderately geoeffective and twenty-five (25) or 29% are not geoeffective. Over the two solar cycles (1996 to 2019), 71% of storms were geoeffective and 29% were not. For solar cycle 23, about 78% of storms were geoeffective, while for solar cycle 24, about 56% were geoeffective. For the statistical study based on speed, 85 halo CMEs associated with X-class flares were selected because the CME of 6 December 2006 has no recorded speed value. For both solar cycles, 75.29% of the halo CMEs associated with X-class flares have a speed greater than 1000 km/s. The study showed that 42.18% of halo (X) CMEs with speeds above 1000 km/s could cause intense geomagnetic disturbances. These results show the contribution (in terms of speed) of each class of halo (X) CMEs to the perturbation of the Earth’s magnetic field. Coronal mass ejections then become one of the key indicators of solar activity, especially as they affect the Earth.

Introduction: Ureteroscopy is a minimally invasive endoscopic surgery which provides access to the ureter, pyelon and calyceal cavities via the urethra and the bladder. Laser ureteroscopy uses the laser as an energy source to treat the stone and eliminate it naturally. Minimally invasive endoscopic methods are struggling to become popular in sub-Saharan African countries, especially for the upper urinary tract. The objective of our work was to report the results of our first laser ureteroscopy experience in the department. Materials and Methods: This was a prospective and descriptive study running from December 1, 2023 to February 19, 2024. Included in our study was any case of upper urinary tract stone operated by Laser ureteroscopy. The characteristics of the lithiasis were determined by CT scan. Sterilization of urine was verified by carrying out a cytobacteriological examination of urine. Ureteral lithiasis was approached by semi-rigid ureteroscopy. Renal lithiasis was immediately addressed by flexible ureteroscopy. Ureteroscopy was coupled with a Holmium YAG laser. A double J ureteral catheter was placed after the operation. A 230 µm laser fiber was used in each case with a generator with a power of 35 watts (Storz Calculase III type). An access sheath was used in all cases of flexible ureteroscopy. The parameters studied were: sociodemographic characteristics, lithiasis (site, size, number, density, topography), type of anesthesia, duration of laser use, duration of intervention, postoperative outcomes. Data entry and analysis were carried out using the software (Word 2016 and SPSS). Result: We collected 30 cases of laser ureteroscopy. The average age was 37 years with extremes of 9 and 79 years. The male gender was more represented. The most common age group was 24-39 years old. Renal colic was the most frequent reason for admission, 12 patients (40%). On physical examination, lumbar tenderness was present in 47% (14 patients). ECBU was positive in 4 patients

Introduction: Deep vein thrombosis is a frequent disease, its origin is most often multifactorial. Venous thromboembolic disease (MVTE) and cancer are two frequently entangled pathologies. Here we report the diagnosis of deep vein thrombosis that discovered prostate cancer in an 88-year-old Guinean man. On clinical examination, there was a painful and hot swelling of the right leg, an absence of sloshing of the calf, a positive sign of Homans. The digital rectal examination revealed an enlarged prostate with an irregular surface. Cardiopulmonary auscultation was normal. The electrocardiogram showed a regular sinus rhythm at 65 cycles/min, with no sign of enlarged cavities or conduction disturbance. Venous Doppler ultrasound of the lower limbs showed the presence of an extensive acute deep venous thrombosis of the right sural vein extended to the popliteal and to the homolateral deep femoral. The reino-vesico-prostatic ultrasound concluded in a heterogeneous prostatic hypertrophy with projection of a median lobe associated with a bladder of fight with an important post voiding residue evaluated at 170 ml;the rate of specific antigen of the prostate PSA was at 84.87 ng/ml. The pathology analysis made after a prostate biopsy puncture concluded with an adenocarcinoma with a Gleason score of 3. Conclusion: The association of venous thromboembolic disease (MVTE) and neoplasia is frequent. The existence of active cancer in a patient is a known risk factor for MVTE and, conversely, the discovery of a first episode of deep vein thrombosis (DVT) or pulmonary embolism (PE) may be the mode of revelation of cancer.

Introduction: Bladder tumors are common in our country;Mali is a bilharzial endemic country. In our context, urinary bilharzia is common, and bladder tumors arouse particular interest in the field of urological oncology, because of their frequency, their diagnosis, their difficulty in management and their histological particularity. The objective of our work was to study the epidemiological, clinical and therapeutic aspects of bladder tumors. Materials and Methods: This is a cross-sectional, descriptive study with a retrospective and prospective collection that took place over 3 years from January 1, 2020 to December 31, 2022. Results: We identified 316 cases of bladder tumors during this period. Bladder tumors are a common pathology representing 35.95% of all hospitalized patients, and occupying the 1st rank of tumors in urology in the Urology Department of the Pr Bocar Sidy Sall University Hospital in Kati. Bladder tumors were more common in men with 56.33%. The average age of our patients was 50 years ± 25.8 years and the extreme ages were 20 and 87 years. Urinary schistosomiasis, considered a predisposing factor, was found in 66.78% of cases in our patients as a history. Transurethral resection of the bladder was performed in 100% of our patients, nephrostomy in 1.90% of cases, ureterostomy in 1.58% of cases, Bricker type urinary diversion in 1.27% of cases, and a neobladder in 0.32% of cases. Squamous cell carcinoma is the dominant histological type (88.29%). The postoperative outcome was 99% favorable after resection. Conclusion: Bladder tumors were mainly tumors infiltrating the bladder muscle. The main risk factor was urinary bilharzia. Squamous cell carcinoma is the most common histological type with a diagnostic delay, thus limiting radical treatment after resection of the bladder tumor.

Nephroblastoma is the most common malignant renal tumor in children and is related to an abnormal proliferation of cells resembling those of the embryonic kidney (metanephroma), hence the terminology;embryonal tumor. These are tumors that remain and remain unstudied in Mali because they are common in adults in our context. Its annual incidence is estimated at approximately 1/10,000 births. Nephroblastoma is a rare or even exceptional tumor in adults. The clinical manifestation was a large swelling of the right hypochondrium;abdominal pain for a year;unquantified fever, hypertension, initial hematuria associated with burning during urination and anemia. The main clinical manifestation remained fever and abdominal pain. This renal tumor posed a diagnostic problem which was previously labeled as a mesenteric tumor in our general surgery department. The diagnosis was made by imaging: CT and magnetic resonance imaging. The treatment is multidisciplinary and combines chemotherapy, surgery with or without radiotherapy. The prognosis is poor due to late diagnosis and less effectiveness of chemotherapy compared to the child. Survival did not exceed a year and a half because the renal tumor in our patient was surgically overcome. We report a case of nephroblastoma in an 86-year-old patient with unfavorable histology (hematogenous metastases), operated on in the general surgery department and whose postoperative course was simple and who was referred to oncology for treatment.

Introduction: HIV, the human immunodeficiency virus, is the etiological agent of acquired immunodeficiency syndrome (AIDS). The aim of this study was to assess the evolution of the viral load in patients under treatment. Methodology: This was a study carried out from July 2017 to June 2022 at the Point G University Hospital laboratory. The determination of the viral load of patients was carried out by PCR on the ABOTT M2000sp/rt platform. Results: A total of 129 patients infected with HIV-1, aged 19 to 72 years with a mean age of 40.05 years ± 10.71;all on antiretroviral chemotherapy. The female gender predominated among our patients. The most common treatment regimen was 2INTI + 1INNTI with 72.9% followed by 2INTI + 1INI with 13.2%. As for the combinations of molecules, the combination TDF + 3TC + EFV and TDF + 3TC + DTG predominated, respectively 65.1% and 13.2%. 89.9% of our patients had undetectable viremia after 12 months of treatment (p < 0.005) with an average viral load which had evolved from 681315.65 copies/ml ± 1616908.484 to M0 at 5742.36 copies /ml ± 35756.883 at M12 (p Conclusion: Generally speaking, antiretroviral treatment had contributed to controlling viral loads, however the therapeutic combination TDF + 3TC + DTG had made it possible to obtain more patients with undetectable viremia instead.

Non-isothermal Decomposition Mechanism and Kinetics of LiClO_4 in Nitrogen

引用

Chemical Research in Chinese Universities 2010年第2期26卷 300-303页

作者： diakite Kahirou College of Chemistry and Molecular Sciences Wuhan University

The non-isothermal decomposition kinetics of LiClO4 in flow N2 atmosphere was studied. TG-DTA curves show that the decomposition proceeded through two well-defined steps below 900℃, and the mass loss was in agreement with the theoretical value. XRD profile demonstrates that the product of the thermal decomposition at 500℃ is LiCI. For the decomposition kinetics study, the activation energies calculated with the Friedman method were considered as the initial values for non-linear regression and were used for verifying the correctness of the fired models. The decomposition process was fitted by a two-step consecutive reaction： extended Prout-Tompkins equation[Bna, f（α） is （1-α）^nα^α] followed by a lth order reaction（F1）. The activation energies were （215.6±0.2） and （251.6±3.6） kJ/mol, respectively. The exponentials n and a for Bna reaction were （0.25±0.05） and （0.795±0.005）, respectively. The reaction types and activation energies were in agreement with those obtained from the isothermal method, but the exponentials were optimized for better firing and prediction.
