The immunosuppressive regimens required for hematopoietic stem cell transplantation predispose recipients to complications, including avascular necrosis. Cancer-related comorbidities, immunosuppression, and poor bone quality theoretically increase the risk for perioperative medical complications, infection, and implant-related complications in total joint arthroplasty. This study reviewed 20 primary total hip arthroplasties for avascular necrosis in 14 patients. Outcomes were assessed at routine clinical visits and Harris hip scores were calculated...

Although the tuberculin test represents the main in vivo diagnostic method used in the control and eradication of bovine tuberculosis, few studies have focused on the identification of mycobacteria in the milk from cows positive to the tuberculin test. The aim of this study was to identify Mycobacterium species in milk samples from cows positive to the comparative intradermal test. Milk samples from 142 cows positive to the comparative intradermal test carried out in 4,766 animals were aseptically collected, cultivated on Lowenstein-Jensen and Stonebrink media and incubated for up to 90 days...

Background and purpose - Mobile-bearing total knee prostheses (TKPs) were developed in the 1970s in an attempt to increase function and improve implant longevity. However, modern fixed-bearing designs like the single-radius TKP may provide similar advantages. We compared tibial component migration measured with radiostereometric analysis (RSA) and clinical outcome of otherwise similarly designed cemented fixed-bearing and mobile-bearing single-radius TKPs. Patients and methods - RSA measurements and clinical scores were assessed in 46 randomized patients at baseline, 6 months, 1 year, and annually thereafter up to 6 years postoperatively...

Introduction: Currently, it is challenging to treat giant cell tumor (GCT) of distal radius. For Campanacci grade III or recurrent GCTs, en bloc resection has been accepted as a better treatment option. Although numerous methods are available for reconstruction, all of them have some limitations in joint function and complications. In this study, our aims were to treat the GCT of distal radius with uncemented three-dimensional (3D)-printed prosthesis and to present and evaluate the surgical techniques and short-term outcomes...

Prosthetic joint failure is mainly caused by infection, aseptic failure (AF), and mechanical problems. Infection detection has been improved with modified culture methods and molecular diagnostics. However, comparisons between modified and conventional microbiology methods are difficult, due to variations in specimen sampling. In this prospective, multidisciplinary study of hip or knee prosthetic failures, we assessed the contributions of different specimen types, extended culture incubations, and 16S rRNA sequencing for diagnosing prosthetic joint infections (PJI)...

Hengyan Zhang, Qiyi Li
RATIONALE: Surgical site infection (SSI) following spine surgeries involving internal fixation often require removing the instrument; however, this can cause spinal instability. Previous reports have demonstrated the usefulness of vacuum sealing drainage (VSD) therapy, but the cases require wound opening, aseptic condition to replace the VSD device, and a secondary operation to close the wound. Thus, to improve the VSD treatment and develop a maneuverable procedure, make sense in spine surgery...

Various therapeutic methods are available to treat patients with intertrochantric fracture, which is usually caused by falling down. This complication is usually observed among the elderly, particularly old women. The choice of the proper therapeutic method depends on many factors including patient's condition, type of fracture, and the amount of movement. Hip arthroplasty is one of these therapeutic methods, which have certain advantages and disadvantages. Immediate resumption of walking with the ability of weight toleration and absence of complications such as aseptic necrosis are some advantages of this method...

The assessment of antibody responses after immunization with radiation attenuated, aseptic, purified, cryopreserved Plasmodium falciparum (Pf) sporozoites (SPZ) (Sanaria® PfSPZ Vaccine) has focused on IgG isotype antibodies. Here, we aimed to investigate if Pf sporozoite binding and invasion inhibitory IgM antibodies are induced following immunization of malaria pre-exposed volunteers with PfSPZ Vaccine. We found that in addition to anti-PfCSP IgG, Malaria pre-exposed volunteers developed anti-PfCSP IgM antibodies after immunization with PfSPZ Vaccine and that these IgM antibodies inhibited Pf sporozoite-invasion of hepatocytes in vitro...

Enterovirus A71 (EV-A71), coxsackievirus A16 (CV-A16), and CV-A6 are the major causative agents of Hand-foot-and-mouth disease (HFMD). These viruses belong to the species Enterovirus A of the genus Enterovirus of the family Picornaviridae. These viruses can also cause aseptic meningitis (AM), encephalitis and/or paralysis. EV-A71 is one of the main infectious agents related to severe encephalitis. Between 1997 and 2013, East and Southeast Asia experienced large encephalitis outbreaks caused by EV-A71 infections, which ranged from severe to lethal...

BACKGROUND: Depression is common in the general population, and so it is likewise common among patients undergoing THA and TKA. Depression is associated with lower perioperative patient-reported outcomes and an increased risk of postoperative complications. Antidepressants are effective in managing symptoms of depression and may potentially contribute to better functional status and better clinical outcomes after THA and TKA. QUESTIONS/PURPOSES: We examined (1) whether perioperative depression is associated with all-cause revisions, revisions for aseptic loosening, revisions without infection, and periprosthetic joint infections (PJIs) in patients undergoing THA and TKA; and (2) whether perioperative antidepressant use reduces the risk of all-cause revisions, revisions for aseptic loosening, aseptic revisions, and PJIs in patients undergoing THA and TKA...
