Background Pulmonary aspergilloma presents in two clinical and radiological forms: simple and complex aspergilloma. Surgery is the best therapeutic option, most often by anatomic lung resection. Our aim was to report the surgical outcomes according to our experience. Methods A retrospective study was conducted on data of 79 patients operated on for pulmonary aspergilloma over a period of 10 years. There were 57 (72.15%) men and 22 women (27.84%), with a mean age of 40.45 years. Results Tuberculosis, all-form combined, was the predominant pathological antecedent in 57 (72.15%) patients, and hemoptysis was the most frequent functional sign in 43 (54.43%). The right side was involved in 39 (49.36%) patients. All patients were operated on via a posterolateral thoracotomy, and an extrapleural plane was necessary in 40 (50.63%). The surgical procedure was a lobectomy in 38 (48.10%) patients and a pneumonectomy in 14 (17.72%). Transfusion of red blood cells was carried out in 10 (12.65%) patients, with one (1.26%) requiring a rethoracotomy for postoperative clotted hemothorax. Two (2.53%) patients presented with empyema after pneumonectomy. The mortality rate was 2.53% (2 patients), and the mean follow-up was 2.5 years. Conclusion Surgery for pulmonary aspergilloma is associated with a high rate of morbidity and mortality. This surgery has been performed in our department with a very acceptable rate of mortality, especially considering that all patients were operated on by open surgery.
BackgroundMalignant mediastinal germ cell tumors are a rare disease and represent only 1% to 4% of all mediastinal tumors. Gonadal germ cell tumors are generally the most common type and constitute 90% of germ cell tumors. The mediastinum is the second most frequently affected area ahead of other extragonadal areas, which include the retroperitoneum, the sacrococcygeal area, and the central nervous system. We report on the case of a mediastinal yolk sac tumor with a complete histological response to chemotherapy.Case presentationA 26-year-old Moroccan man, without a medical or surgical history, presented with a four-month history of chest distress, dyspnea, and a frequent dry cough for the previous month. A computed tomographic scan of the chest revealed a bulky mediastinal mass, which was biopsied. Histologically, the tumoral mass proved to be a yolk sac tumor. The serum level of alpha-fetoprotein of this patient was elevated to 19052 ng/ml.After 4 courses of preoperative chemotherapy, the patient underwent a surgical resection of the tumor, with a complete pathologic response.At the time of writing, the patient is alive with complete remission without any evidence of recurrence.ConclusionPrimary mediastinal Yolk sac neoplasm represent a unique entity, and as such require specialized management. The diagnosis should be made not only by morphological studies but the patient’s age and the elevation of serum alpha-fetoprotein should also be considered. The utilization of cisplatin-based chemotherapy is associated with the best chance of a cure for this disease. This should be followed by surgical resection of the residual tumor in the nonseminomatous germ cell tumor.
Background Neonatal sepsis remains an important cause of morbidity and mortality. The ability to quickly and accurately diagnose neonatal sepsis based on clinical assessments and laboratory blood tests remains difficult, where haemoculture is the gold standard for detecting bacterial sepsis in blood culture. It is also very difficult to study because neonatal samples are lacking. Methods Forty-eight newborns suspected of sepsis admitted to the Neonatology Department of the Mother-Child Specialized Hospital of Tlemcen. From each newborn, a minimum of 1–2 ml of blood was drawn by standard sterile procedures for blood culture. The miRNA-23b level in haemoculture was evaluated by RT-qPCR. Results miR-23b levels increased in premature and full-term newborns in early onset sepsis (p < 0.001 and p < 0.005 respectively), but lowered in late onset sepsis in full-term neonates (p < 0.05) compared to the respective negative controls. miR-23b levels also increased in late sepsis in the negative versus early sepsis negative controls (p < 0.05). miR-23b levels significantly lowered in the newborns who died from both sepsis types (p < 0.0001 and p < 0.05 respectively). In early sepsis, miR-23b and death strongly and negatively correlated (correlation coefficient = − 0.96, p = 0.0019). In late sepsis, miRNA-23b and number of survivors (correlation coefficient = 0.70, p = 0.506) positively correlated. Conclusions Lowering miR-23b levels is an important factor that favours sepsis development, which would confirm their vital protective role, and strongly suggest that they act as a good marker in molecular diagnosis and patient monitoring.
Leiomyoma of the mediastinum is rare. We report a case of a 57-year-old woman with a cervical mass diving to the intrathoracic. Chest radiography and computed tomography revealed a mass in the right superior mediastinum. The tumor was enucleated by cervicotomy. Histologically, the tumor was diagnosed as leiomyoma.
