The Huizhou sag is situated on the continental shelf of the northern continental margin of the South China Sea. In this paper we present a grid of reflection seismic and well data to characterize the basin structure and prominent unconformities. We employ EbM and 2DMOVE softwares to explore the subsidence history and stratigraphic development history of the basin. We found a rapid subsidence period since 15.5 Ma. Moreover, we calculated the stretching factors of the upper crust and the whole crust in the Huizhou sag. The results show the values are 1.10–1.13 and 1.08–1.31, respectively, indicating faulting in Huizhou sag is relatively small. It is noteworthy that the faults map reveals en echelon distribution at the north and south margins of the basin. We suggest en echelon faults here are caused by the subduction of Proto-South China Sea toward NW borneo block and cease of the South China Sea. Considering the pronounced unconformities, subsidence rates, fault activities and sediment thickness, the Cenozoic tectonic evolution of the basin can be divided into rifting（49–32 Ma）, post-rifted（32–15.5 Ma） and rapid subsidence（15.5–0 Ma） stages. Our study will shed new light on the tectonics of SE Asia and petroleum exploration in the South China Sea.

Takayasu disease is a chronic vasculitis of the large vessels. It is rare in sub- Saharan Africa and probably under-diagnosed. Arterial hypertension (AH) is a frequent finding. We report the case of a 46-year-old man with Takayasu disease revealed by hypertension. The American College of Rheumatology (ACR) criteria were used for diagnosis, with 4 out of 6 criteria. Echodoppler and angioscanner showed signs of left subclavian stenosis and circumferential, regular arterial thickening. He had a biological inflammatory syndrome. He was treated with prednisone and amlodipine. After 6 months of follow-up, he was diagnosed with tuberculosis and put on anti-tuberculosis treatment.

Scleroderma (or systemic sclerosis) is a disease characterized by abnormalities in the functioning of small blood vessels and the immune system, ultimately leading to inflammation and excessive fibrosis of the skin and various organs, including the heart. Management must be multidisciplinary, to avoid complications that are often serious. We report the case of a 20-year-old patient with no known cardiovascular history who consults for dyspnea, and retrosternal pain associated with a dry cough. On physical examination, she had tachycardia, swelling of the lower limbs, jugular turgidity, and deafening heart sounds. Cardiac Doppler ultrasound shows dilation of the right cavities, paradoxical septum and significant pulmonary arterial hypertension, pericardial effusion of medium abundance. On oral examination, it presents an ulceration of the lips, dermatological examination finds scattered hypo chromic spots in the body, more accentuated in the face. before the hypo chromic dermatosis, a dermatological consultation was carried out with an autoimmune assessment that came back positive for systemic scleroderma.

Introduction: High blood pressure is a major public health problem worldwide due to its frequency and cardiovascular complications. Adherence to treatment for chronic diseases is a global problem. The aim was to study therapeutic adherence in hypertensive patients followed in ambulatory. Materials and Methods: This was a cross-sectional, descriptive study with prospective recruitment that took place from July 1 to December 31, 2022 (6 months) in the cardiology department of the university hospital of Kati. The variables studied were sociodemographic data, cardiovascular risk factors, comorbidities, the possession of insurance and compliance (the Girerd questionnaire was used to assess adherence). Results: A total of 1182 patients were consulted, including 887 for hypertension, a frequency of 75%. Fifty-six patients were included in the study. The average age was 58.18 ± 13.25 years with extremes of 30 and 80 years. There was a female predominance (75%) with a sex ratio of 0.3. The majority of patients lived in urban areas (89.3%). Out-of-school patients accounted for 44.6%, more than half of patients or 55.4% had no income, patients with medical coverage accounted for 67.9% of cases. The main risk factors were physical inactivity (25%) followed by smoking 14.3%. More than 71% of patients had a compliance problem and the main reasons were forgetting to take the drug with 73.2%, followed by delayed treatment of 50% and drug discontinuation of 28.6%. Conclusion: Compliance is a real challenge and a major public health issue. This study allowed us to find a real problem of compliance in our hypertensive patients. There was a statistically significant relationship between drug adherence and forgetting to take the drug and drug discontinuation.

Objective: Renal failure (RF) is a serious condition that is still insufficiently evaluated in our context. We wanted to know its epidemiology at the Pediatrics University Hospital Center Charles De-Gaulle (PUHC-CDG) of Ouagadougou. Patients and Methods: We retrospectively studied all children aged from three to fifteen years old who were diagnosed with renal failure (RF) in the Department of Medical Pediatrics, from January 1, 2011 to December 31, 2013. RF was defined by a glomerular filtration rate (GFR) less than 80 mL/min/1.73m2, estimated by the formula of Pottel et al., which ignored the size that was rarely found in the medical records. The department constantly lacked pediatric blood pressure monitors or urinary strips. Results: In total, 119 cases of RF (3.3% of all admissions) were collected. They were about acute RFs (ARFs), chronic RFs (CRFs), and Unclassified RFs (URFs), respectively in 28.6%, 2.5% and 68.9% of cases. The overall average age of patients was 6.7 ± 3.4 years old. The average GFR was 35.2 ± 22.2 mL/min/1.73m2. The mechanism of ARF was presumed to be organic in 26 cases (76.5%). The most common presumed etiology was malaria (47.9%). Twelve patients (10.1%) died. Conclusion: RF was common at the PUHC-CDG but it was unclassified in over half of the cases. The diagnosis was based on the estimation of the GFR by Pottel et al.’s formula which was a good alternative to the Schwartz’s formula. The improvement of human and material resources would certainly help for a screening and characterization of RF at the PUHC-CDG.

background: A cardiovascular assessment is rarely performed among athletes despite more and more frequently reported fatal events. Most of these accidents are of cardiovascular origin. Moreover, data on ECG or Echocardiography are rare in our context justifying our study to assess electrical and echocardiographic pattern among high-level footballer in bamako. Methods: It was a cross-sectional study conducted in bamako from April 2015 to?March 2016 among high-level footballers aged 14 to 35 years old without distinction of sex with at least 10 hours weekly training since one year. The ECG and echocardiographies were recorded respectively with a 12-lead CONTEC and an ATL 5000 echocardiographic machine. Each ECG record was analyzed by a cardiologist in accordance with the Seattle 2013 criteria and those pathological reviewed by a second cardiologist according to the same criteria and definitively classified as normal (physiological) or abnormal ECG (requiring complementary explorations). A third cardiologist was associated in case of discordance of the first results. The collected data were inserted in a Microsoft Excel sheet and analyzed with SPSS version 20. Chi Square and Fisher statistical tests were used to compare our results. The significance level was set at 0.05. Results: We collected data of 227 top footballers with male sex represented in 90.3% giving a sex ratio of 3.04. Means for age, weight, height, body mass index (bMI) were respectively 22 years, 69.90 kg, 177.21 cm and 22.21 kg/m2. Sinus bradycardia was found in a proportion of 45.8% more represented in the age group of 30 and more years (p = 0.275). First-degree atrioventricular block (AVb) was present in 19.4%. Short PR was found in 0.4% of the sample. Left ventricular hypertrophy (LVG) according to the Sokolow index was found in 70.5% (96.9% males and 3.1% females) with p Conclusion: Many electrical and echocardiographic signs of cardiac adaptation were found in our sample and must lead to a closer
