This article focuses on a new insight into the energy classification of sublayers. In this article, the study brings out very interesting and enriching information, knowledge and knowledge in atomistics. An affine function is represented in an orthonormal frame while assimilating a point to a sublayer. This made it possible to draw up a graph integrating each of the diagrams of the known energy levels. Our results are conclusive. We can then confirm that the research hypothesis is verified.

Introduction: Congenital heart disease includes all cardiac and vascular malformations. It accounts for approximately one third of all congenital malformations and is a public health problem, particularly in developing countries. The aim of this study was to analyze the epidemiological, clinical and paraclinical aspects of congenital heart disease. Methods: This was a retrospective descriptive and analytical study based on the records of 135 patients referred for surgery and followed up in the cardiology department of the Ignace Deen University Hospital, collected in November 2022. Results: Hospital prevalence was 5%. The mean age was 71 months, ranging from 1 month to 19 years. The age group over 24 months was the most represented (62%). The M/F sex ratio was 1.36. Urban origin was predominant (58%). The rate of children not attending school or dropping out was high (16%). Siblings with fewer than 4 children were the most common (88%). A heart murmur was the most frequent sign (78%), followed by cyanosis (36%) and heart failure (29%). The association between heart murmurs and CHD was proven with a p-value Conclusion: CHDs represent the main indication for paediatric cardiac surgery and follow-up (95%). We stress the importance of implementing a screening and management strategy for congenital heart disease.

This study aims to enhance the healthcare services for diabetic patients in the administrative region of Kindia by suggesting dietary interventions to assist diabetics in better managing their condition. Conducted over a period of six months, from February 18 to July 18, 2021, this prospective and descriptive cross-sectional study involved 220 diabetic patients. Among these, 48 patients (22%) maintained balanced glucose levels (2 g/l). Positive glycosuria was observed in 54% of the patients, whereas 46% demonstrated normal glycosuria. An analysis of urinary parameters revealed that 15% of the patients had abnormal Ketone Bodies. Normal HbA1c levels (9%) HbA1c levels. Hematological assessments indicated significant variation: 56% of the patients had low hemoglobin levels, 4% suffered from hyper-eosinophilia, and 1% each from hyper-basophilia and hyper-hemoglobinemia. The anemic profile was characterized as mild anemia in 75%, moderate anemia in 20%, and severe anemia in 5%. Furthermore, 25% of patients were affected by Microcytic anemia and 75% by Normocytic anemia. Demographically, women constituted 65% of the study group compared to 35% of men. The most represented age bracket was 41 to 60 years, accounting for 52% of the patients, while those between 61 and 80 years comprised 36%. Every district in Kindia was impacted by diabetes.

Introduction: Cystic lymphangiomas are rare benign malformative tumors of the lymphatic system of obscure etiopathogenesis. The cervico-facial location remains the most common (75%). Although benign, these tumors remain potentially fatal, due to possible compression of the upper aero-digestive tract. The aim of this work is to study the epidemiological, diagnostic and therapeutic characteristics of cervico-mandibular congenital cystic lymphangiomas in the pediatric surgery department of the Donka National Hospital (HND) Conakry. Patients and methods: This is a retrospective and descriptive study of 13 files lasting 7 years from January 2015 to December 31, 2021. The files of children whose age is less than or equal to 15 years operated on cervical tumor with histological evidence of cystic lymphangioma were retained. The data were analyzed using SPSS statistical software 21 and anonymously. Results: The incidence of this study was 1.86 cases per year and a sex ratio of 0.62 in favor of girls. The average age was 8 months 19 days. In the antecedents, we only find poorly monitored pregnancies. The average size of the tumors was 11.85 cm. Cervical ultrasound and standard x-ray of the cervical mass were the only examinations performed. Total surgical excision of the cervical tumor was performed in all patients. The mass was polycystic on exploration. The histological examination of the surgical specimens was in favor of a cystic lymphangioma. The surgical consequences were simple in 11 patients (84.62%) and complicated by parietal suppuration in 2 cases (15.38%). There were no cases of recurrence after one year of follow-up. Conclusion: Cervico-mandibular cystic lymphangiomas are the most frequent locations of congenital lymphangiomas in children. Their severity is linked to the risk of compression of the aero-digestive tracts. Their diagnosis must be confirmed by the histology of the surgical specimen. Despite the therapeutic arsenal, excision of the cystic mass remain

Vaccination against COVID-19 is the most recognised means of containing the pandemic. Vaccines are not without side effects, particularly vascular thrombosis. But before blaming the vaccines, a thorough assessment of thrombotic risk factors is necessary. We report a case of arterial and venous thrombosis after vaccination with AstraZeneca revealing an exaggeration of factor VIII in a 37-year-old female patient. The angioscanner showed a venous thrombosis of the right subclavian, a pulmonary embolism and the presence of a thrombus in the aorta. The biology was in favour of a high level of factor VIII. The patient was treated with an antivitamin K, and the clinical evolution was favourable.

The intercostobrachial nerve (ICBN) is responsible for the sensory innervation of a part of the inner side of the arm. Injury of the intercostobrachial nerve is a complication of axillary dissection during lymph node dissection. Objective: This study aimed to determine the effect of preservation of the intercostobrachial nerve on postoperative sensory disturbances. Methods: This is a prospective, single-center study which was carried out in 90 patients followed in the oncology department of the Aristide Le Dantec hospital in Dakar, suffering from breast cancer and having undergone breast surgery associated with axillary dissection, for a period of 6 months. The patients were divided into two groups depending on whether the intercostobrachial nerve (ICBN) was preserved or not. The two groups were compared in terms of the incidence of sensory disturbances. Results: Sixty patients without nerve preservation and 30 patients with nerve preservation were included in the study, i.e., 90 patients in total.

Non-isthmic coarctation of the aorta is a rare congenital malformation in adults. Arterial hypertension is a frequent circumstance of discovery. We reported the case of a 22-year-old Guinean man who had been followed for 5 years for hypertension. Clinically, he presented with hypertension of the upper limbs with a systolic pressure gradient of 100 mmHg. The diagnosis was confirmed by thoracic angioscan, which showed a 65.8% coarctation of the abdominal aorta. He was on triple antihypertensive therapy combining Atenolol 100 mg, Amlodipine 10 mg and Perindopril 10 mg. He is awaiting interventional treatment. His blood pressure is stable at around 140/90 mmHg.
