This technique applies to electrical parameters such as the short-circuit current (Jcc) and the open-circuit voltage (Vco). These parameters are mainly related to the variations in the doping rate and the thickness of the solar cell. So, optimizing these parameters could offer the possibility of better taking into account the influence of temperature and improving the quality of the solar cell. This technique consists of determining the optimum thickness and the optimum doping rate. And this allowed us to observe using graphs the behavior of the solar cell under different values of temperature.展开更多

The prognosis depends on the diagnostic delay and above all on the speed of treatment. It usually occurs in a particular area such as myeloproliferative syndrome, sickle cell anemia, thalassemia etc. The objective of this work was to report a clinical case of necrosis of the spleen.展开更多

We report the case of a 35-year-old female with uncontrolled diabetes mellitus, presenting with edema of the neck, facial and left mammary gland, secondary to untreated dental infection, progressing to a full-blown necrotizing fasciitis in a short period of time with sepsis. The patient was managed with aggressive multidisciplinary medical and surgical treatment. Despite the technologic advances in diagnosis and treatment, complications still result with astounding high mortality. Clearly, the morbidity associated to this infection, even in diabetic patients, can be minimized if an early diagnosis and effective debridement are done.展开更多

This is evidenced by Ambroise Paré’s decision to publish his first work on this subject, “La manière de traiter les Plaies” (The Way of Treating Wounds) in 1545. Objective: To evaluate the therapeutic methods we practice and to describe the impact of the pathology on socio-economic and professional development. Patients and Method: This was a retrospective study carried out at the Fousseyni Daou Hospital in Kayes from January 1, 2018, to December 31, 2020. We included all patients with an ulcero-necrotic wound on immunocompetent terrain hospitalized in the department. Patients with ulcerative necrotic wounds of diabetes, HIV, or cancerous origin were not included. The parameters studied were: etiologies, local care, sequelae, and socio-economic and professional aspects. Results: We collected 57 patients of whom 43 were men and 14 were women, i.e. a sex ratio of 3. The mean age was 40.7 years with a standard deviation of 8.4 with extremes (7 years and 80 years). The average consultation time was 25.1 days. The most represented socio-professional stratum was agropastoralism in 37 cases (65%). The predominant etiological factor was neglected traumatic wounds in 34 cases (59.6%). The site was the lower limb in 39 cases (68.5%). The germ found was Staphylococcus aureus in 21 cases (36.8%). The particularity during local care was the use of table sugar in 9 cases (15.7%) and maggot therapy in 2 cases (3.5%). Hyperthermia was the clinical sign of aggravation in 22 cases (38.6%) and we diagnosed 2 cases (3.5%) of tetanus. The mortality rate was 15.7% (9 cases) and 30 cases (52.7%) of sequelae after recovery. The average length of hospitalization was 38 days. Hospital care was provided by the social welfare service in 35 cases (61.4%). Nineteen (19) patients (39.5%) were unable to resume their socio-professional activity. Conclusion: Ulcero-necrotic wounds are complex to manage and can have a lifelong influence on the socio-professional and economic activity of patients.展开更多

Because of its rarity and its coexistence with more injuries, the diagnosis is often delayed. Very little has been written about this condition in the pediatric age group. TDR, while uncommon, should be considered in cases of blunt thoracic trauma. All patients should undergo meticulous examination preoperatively. The clinical presentation and importance of making an accurate diagnosis and surgery is highlighted. We report a case of secondary spontaneous traumatic left-sided diaphragmatic rupture in a child that was managed by delayed surgical repair.展开更多
