肱骨在不属于工会一严重地如果破裂是横向的， osteoporotic 骨头特别是一个可能的事件。如此的联合的管理是挑战。当骨头失败领先，大多数常规固定方法是不大可能的成功在骨质疏松症植入失败。当外皮的厚度更严重地被影响时，挑战进一步在严重骨质疏松症被加重。我们在 5 种情况中与一个锁住的盘子使用了一根 intramedullary 腓骨的联合。当骨头力量被扩充，板撤退多半是更少，结果证明它可以是处于如此的状况的好联合。

OBJECTIVE:Rubber bullets are considered a non-lethal method of crowd control and are being used over the world. However the literature regarding the pattern and management of these injuries is scarce for the forensic pathologist as well as for the traumatologist. The objective of this report was to add our experience to the existing literature.;METHODS:From June 2008 to August 2010 the Government Hospital for Bone and Joint Surgery Barzulla and the Department of Orthopaedics, SKIMS Medical College/Hospital Bemina Srinagar received 28 patients for management of their orthopaedic injuries caused by rubber bullets. We documented all injuries and also recorded the management issues and complications that we encountered.;RESULTS:All patients weremales with an age range of 11e32 years and were civilians who had been hit by rubber bullets fired by the police and the paramilitary forces. Among them, 19 patients had injuries of the lower limbs and 9 patients had injuries of the upper limbs. All patients were received within 6 h of being shot.;CONCLUSIONS:Our findings suggest that these weapons are capable of causing significant injuries including fractures and it is important for the surgeon to be well versed with the management of such injuries especially in areas of unrest. The report is also supportive of the opinion that these weapons are lethal and should hence be reclassified.

Introduction: The treatment of viral hepatitis C (HCV), a major public health problem, has evolved considerably since the introduction of direct-acting anti-virals (DAAs). The aim of this study was to evaluate the strategy for initiating treatment with Sofosbuvir/Daclatasvir, and also to assess its efficacy. Patients and Methods: Included were patients aged at least 15 years, with detectable hepatitis C viremia and treated with a pan-genotypic Sofosbuvir/Daclatasvir regimen at the Centre “Hospitalier Universitaire la Référence Nationale de N’Djamena” between October 2019 and October 2023. The APRI score was used to assess fibrosis. Cure was defined by an undetectable viral load 12 weeks after the end of treatment. Results: A total of 835 patients were included (sex ratio 1.55, mean age 50.5 ± 13.73, extremes 20 and 84 years). The 60 - 69 age group was the most represented. The mean APRI score was 0.42 ± 0.29, with extremes of 0.019 and 1.84. The mean viral load was 2,316,193.086 IU/mL. All subjects had good renal function. Cytolysis was absent in 70% of cases. Without genotyping, a pan-genotypic regimen was used in all patients: Sofosbuvir (400 mg)/Daclatasvir (60 mg). The cure rate was 99.4%, with good tolerability. However, four cases of failure were recorded out of the 668 patients who underwent follow-up HCV-PCR testing after 12 weeks of treatment. Conclusion: The Sofosbuvir/Daclatasvir regimen is highly effective, with an excellent safety profile. However, the still high cost of these molecules limits their accessibility to a large proportion of patients.
