The subtrochanteric fractures are relatively rare in the child and they constitute a therapeutic problem. The pseudarthrosis of this fracture in the child is often the complication of a subtrochanteric fracture treated orthopedically. We report the case of a subtrochanteric pseudarthrosis in a 5 year-old child occurred following an orthopedic treatment. After surgical treatment by bloody reduction and pinning, the pseudarthrosis consolidated in 10 months with satisfactory functional results.

Background: Lumbar paraspinal hemangiopericytoma is rare. The hemorrhagic nature of the tumor causes problems of hemostasis and makes the resection delicate. We report a rare case of lumbar paraspinal hemangiopericytoma managed with preoperative embolization. Clinical Case: It is about a woman of 31 years, admitted for a large left lumbar paraspinal mass that evolved for 6 years. The clinical exam showed an asymmetry of the left paraspinal muscle. The mass painless was extended from the lumbar region. The neurological exam was normal. MRI showed the left large paraspinal mass tissue. It was extended from lumbar vertebrae, L1 to L4, and measured 100 × 50 × 50 mm. It was an iso-intense signal on T1-weighted with strong enhancement after gadolinium. It was hypervascular and supplied by left intercostal T12, L1, and L2 pedicles. The complete exclusion of the hyper-vascular left paraspinal tumor was obtained after selective embolization of the artery left L1 of the pedicle of the intercostal left L1 and trunks intercostal T12 and L2 left. The total resection of a mass encapsulated was performed. The operative outcome was good. The histology concluded to a hemangiopericytoma. No chemotherapy or radiotherapy was prescribed. After 5 years, the patient was asymptomatic. MRI control confirmed tumor resection with a residue at the level of the left intervertebral foramen L1 - L2. Conclusion: Lumbar paraspinal hemangiopericytoma is an extremely rare tumor. Selective preoperative embolization is recommended before the resection of large tumors to reduce vascular supply. A follow-up extended for these patients is necessary, given the frequency of recurrences.

Introduction: Para-spinal non-metallic foreign bodies (fabrics or plastics) are rare and poorly documented. They are often unknown and discovered at the stage of infectious complications and present big therapeutic challenges. We report a rare case of three para-spinal foreign bodies (fabric, plastic and postoperative gauze) discovered during surgery of a traumatic thoracic spine. Case report: A 32-year-old man admitted for a polytrauma (collision motorcycle-cart). The admission examination noted closed trauma of the thoracic spine, an ASIA score of A, dyspnea, a penetrating wound of the left side of the chest. The CT scan showed a compressive left pleural effusion, multiple ribs fractures, pulmonary contusion, unstable fracture of fifth and sixth thoracic vertebrae associated with posterior epidural hematoma responsible for medullar compression. There was a rounded, para-spinal image, dotted with small areas of low density, air bubbles. We lifted the vital emergency by draining the left pleural effusion, debriding the penetrating chest wound, and administering broad-spectrum antibiotic therapy. Fourteen days later, we decided to stabilize the spine. After a posterior approach, we discovered free pus and para-vertebral three foreign bodies. Enterobacter *** isolated in pus susceptible to imipenem. The immediate operative follow-up was simple. Conclusion: The best treatment remains preventive by simple measures, exploration of penetrating wounds, repeated count and careful verification of gauze, because the infectious complications that they generate are source of mortality and serious medico-legal implications.

Background: From May 2018 to September 2022, the Democratic Republic of Congo (DRC) experienced seven Ebola virus disease (EVD) outbreaks within its borders. During the 10th EVD outbreak (2018–2020), the largest experienced in the DRC and the second largest and most prolonged EVD outbreak recorded globally, a WHO risk assessment identified nine countries bordering the DRC as moderate to high risk from cross border importation. These countries implemented varying levels of Ebola virus disease preparedness interventions. This case study highlights the gains and shortfalls with the Ebola virus disease preparedness interventions within the various contexts of these countries against the background of a renewed and growing commitment for global epidemic preparedness highlighted during recent World Health Assembly *** text: Several positive impacts from preparedness support to countries bordering the affected provinces in the DRC were identified, including development of sustained capacities which were leveraged upon to respond to the subsequent coronavirus disease 2019 (COVID-19) pandemic. Shortfalls such as lost opportunities for operationalizing cross-border regional preparedness collaboration and better integration of multidisciplinary perspectives, vertical approaches to response pillars such as surveillance, over dependence on external support and duplication of efforts especially in areas of capacity building were also identified. A recurrent theme that emerged from this case study is the propensity towards implementing short-term interventions during active Ebola virus disease outbreaks for preparedness rather than sustainable investment into strengthening systems for improved health security in alignment with IHR obligations, the Sustainable Development Goals and advocating global policy for addressing the larger structural determinants underscoring these ***: Despite several international frameworks established at the global level for e
