Vaping is affecting the younger and healthier population which is a public concern. Mycoplasma pneumoniae pneumonia is a benign condition and is usually underdiagnosed and is managed in an outpatient setting. Here we present a case of fulminant MPP in a young adult probably associated with VAPI. A 24-year-old woman presented to our hospital for severe hypoxic respiratory failure needing intubation and intensive care unit admission. She had a history for vaping for 2 years prior to presentation. She had fever and an elevated white count. Her Chest X-Ray and CT scan of the chest were consistent with bilateral predominantly lower lobe patchy opacities. She had mildly elevated serum LDH and Urine toxicology screen was positive for THC. Serum IgM Mycoplasma level was positive and her BAL fluid analysis showed lipid-laden macrophages. She was diagnosed as a probable case of VAPI per CDC guidelines with superimposed fulminant MPP. Vaping is known to increase the risk of viral and bacterial pneumonia by compromising the respiratory local immune response. Vaping also causes lipoid pneumonia where the alveoli are filled with lipid-laden macrophages with surrounding inflammation. We hypothesize that this patient had fulminant MPP in the setting of background VAPI. The association between vaping and MPP infection has not been established in the literature and this is the first documented report to establish a link between e-cigarettes and fulminant MPP. Further research is needed to confirm this association. © 2020 The Authors.Lateral meniscus lesions result in loss of meniscus hoop stresses and can lead to lateral compartment overload and early degenerative changes. Arthroscopic suture repair provides good long-term results. However, posterior vertical tears in the peripheral area of the meniscus can be technically challenging to resolve. This Technical Note describes the suture hook technique using an accessory posterolateral portal. We believe it is a safe, effective method for repairing full vertical tears of the lateral meniscus. © 2019 by the Arthroscopy Association of North America. Published by Elsevier.Small intercondylar notch size is associated with increased risk of anterior cruciate ligament (ACL) injuries and increased difficulty of ACL reconstruction. When encountering a small notch during surgery, some surgeons may resort to a notchplasty, which has been shown to have associated morbidity. The ability to predict notch size on preoperative imaging could allow the orthopaedic surgeon to anticipate surgical difficulty such as an oversized graft and graft impingement and possibly avoid a notchplasty. Many methods have been proposed for measuring intercondylar notch size, but they do not correlate with intraoperative measurements or they utilize computed tomography scanning, which is not readily obtained before ACL reconstruction. The purpose of this study was to develop a method of notch measurement on preoperative radiography and magnetic resonance imaging that match intraoperative arthroscopic measurements. The method presented here can be used to identify narrow intercondylar notches, prepare for potential intraoperative challenges, and formulate surgical plans such as for graft choice in individualized ACL reconstruction. © 2019 by the Arthroscopy Association of North America. Published by Elsevier.Abductor tendon tears are one of the common causes of recalcitrant laterally based hip pain and dysfunction. In most cases, abductor tendon tears are associated with chronic nontraumatic tearing of the gluteus medius tendon. Restoring abductor function of the hip by primary repair of the gluteus medius tendon has been reported to have good and excellent outcomes. [https://www.selleckchem.com/products/importazole.html Importazole ic50] However, primary repair might not be as effective for chronic detachment of the gluteus medius tendon with a wide separation from the femoral footprint or severe tendon loss. The lack of tendinous foot for repair and the intrinsically degenerative condition of the tendon may create high tension at the repair site thereby predisposing to surgical failure. We believe that the use of soft-tissue allograft from the Achilles tendon or human dermal allograft may help strengthen the surgical site. We describe a superior gluteal reconstruction technique that is suitable for cases with abductor tendon tear with severe tendon loss. © 2019 by the Arthroscopy Association of North America. Published by Elsevier.This is a technique guide for open anterior capsule reconstruction in unstable native hips due to Ehlers-Danlos syndrome. Ehlers-Danlos syndrome is a connective tissue disease that predisposes an individual to hypermobility of their soft tissues and recurrent subluxations and dislocations of their joints. This may lead to constant instability, guarding of the hip, and subsequent arthritic changes and poor quality of life. We demonstrate anterior capsule reconstruction of the hip using an Achilles tendon allograft performed through a direct anterior approach to the hip (Heuter's approach). This technique guide outlines in detail the surgical steps required to accomplish this reconstructive procedure. Furthermore, a narrated surgical video is provided that clearly depicts the anticipated result of the increased constrained provided to the hip from the anterior capsule reconstruction using an Achilles tendon allograft. © 2019 by the Arthroscopy Association of North America. Published by Elsevier.Revision surgery after failed primary anterior cruciate ligament reconstruction is technically demanding. In cases in which the tunnels of the primary anterior cruciate ligament reconstruction are widened to greater than 10&nbsp;mm and/or are incorrectly positioned, a 2-stage procedure enables restoration of bone stock and thus free placement of the tunnels during the revision. The gold standard for tunnel augmentation is an autologous iliac crest cancellous bone graft. However, harvesting the graft is associated with high morbidity. This article describes an alternative method for managing bone deficiencies using the synthetic bone graft substitute silicate-substituted calcium phosphate. © 2019 by the Arthroscopy Association of North America.
