BACKGROUND: Periprosthetic joint infection after total knee arthroplasty is commonly treated via 2-stage revision utilizing either articulating or static antibiotic cement spacers. While recent literature exhibits a slight functional advantage in favor of articulating spacers, those patients with a history of recurrent infection/multiple revision procedures are frequently excluded from these studies. The purpose of this study was to report infection eradication rates and efficacy of utilizing antibiotic-loaded locked intramedullary nail for infection for the multiply revised, infected total knee arthroplasty...

Engineering cardiac implants for treating myocardial infarction (MI) has advanced, but challenges persist in mimicking the structural properties and variability of cardiac tissues using traditional bioconstructs and conventional engineering methods. This study introduces a synthetic patch with a bioactive surface designed to swiftly restore functionality to the damaged myocardium. The patch combines a composite, soft, and conductive hydrogel-based on (3,4-ethylenedioxythiophene):polystyrene-sulfonate (PEDOT:PSS) and polyvinyl alcohol (PVA)...

PURPOSE: Resection of sacral neoplasms such as chordoma and chondrosarcoma with subsequent reconstruction of large soft tissue defects is a complex multidisciplinary process. Radiotherapy and prior abdominal surgery play a role in reconstructive planning; however, there is no consensus on how to maximize outcomes. In this study, we present our institution's experience with the reconstructive surgical management of this unique patient population. METHODS: We conducted a retrospective review of patients who underwent reconstruction after resection of primary or recurrent pelvic chordoma or chondrosarcoma between 2002 and 2019...

AIMS: Surgical site infection (SSI) after soft-tissue sarcoma (STS) resection is a serious complication. The purpose of this retrospective study was to investigate the risk factors for SSI after STS resection, and to develop a nomogram that allows patient-specific risk assessment. METHODS: A total of 547 patients with STS who underwent tumour resection between 2005 and 2021 were divided into a development cohort and a validation cohort. In the development cohort of 402 patients, the least absolute shrinkage and selection operator (LASSO) regression model was used to screen possible risk factors of SSI...

Ticks are arachnid ectoparasites that rank second only to mosquitoes in the transmission of human diseases including bacteria responsible for anaplasmosis, ehrlichiosis, spotted fevers, and Lyme disease among other febrile illnesses. Due to the paucity of data on bacteria transmitted by ticks in Kenya, this study undertook a bacterial metagenomic-based characterization of ticks collected from Isiolo, a semi-arid pastoralist County in Eastern Kenya, and Kwale, a coastal County with a monsoon climate in the southern Kenyan border with Tanzania...

Rheumatic diseases are a group of conditions including arthritis and various other conditions that can lead to chronic inflammation within the musculoskeletal system, which can have negative effects on soft tissues, bones, muscles, joints, and connective tissue. One form of arthritis is gout, which is an inflammatory condition in which urate acid crystals build up in joints. Gout is associated with joint swelling, pain, redness, and joint mobility issues. Early diagnosis and treatment are essential to prevent joint degradation and other adverse complications...

METHODS: This study is a single-institution retrospective review of consecutive patients who required plastic surgery intervention for wound infection following spinal procedures between the years 2010 and 2021 (n = 70)...

BACKGROUND: Nearly 25% of antibiotics prescribed to children are inappropriate or unnecessary, subjecting patients to avoidable adverse medication effects and cost. METHODS: We conducted a quality improvement initiative across 118 hospitals participating in the American Academy of Pediatrics Value in Inpatient Pediatrics Network 2020 to 2022. We aimed to increase the proportion of children receiving appropriate: (1) empirical, (2) definitive, and (3) duration of antibiotic therapy for community-acquired pneumonia, skin and soft tissue infections, and urinary tract infections to ≥85% by Jan 1, 2022...

INTRODUCTION: Olecranon fractures with compromised overlying skin such as superficial and deep abrasions and puncture wounds pose a challenge to manage as they are at a higher risk of wound and hardware-associated complications such as wound dehiscence, infection, gaping, and prominent hardware. Management of such fractures requires a holistic approach with special attention to the skin and soft tissues. CASE REPORT: This case highlights a 28-year-old male with a history of falls from a bike resulting in the right comminuted displaced olecranon fracture with multiple superficial abrasions which was managed with a thorough wound wash, antibiotics for 3 days after which percutaneous tension band wiring was performed through a 3 cm incision to prevent any wound complications...

Osteolyses are common findings in elderly patients and most frequently represent malignant or locally aggressive bone tumors, infection, inflammatory and endocrine disorders, histiocytoses, and rare diseases such as Gorham-Stout syndrome. We here report on a novel entity of massive multifocal osteolyses in both shoulders, the right hip and left knee joint and the dens of an 83-year-old patient not relatable to any previously known etiopathology of bone disorders. The soft tissue mass is of myxoid stroma with an unspecific granulomatous inflammatory process, aggressively destroying extensive cortical and cancellous bone segments and encroaching on articulating bones in diarthrodial large joints...

Introduction: Failure of alloplastic breast reconstruction is an uncommon occurrence that may result in abandonment of reconstructive efforts or salvage with conversion to autologous reconstruction. The purpose of this study was to identify factors that predict failure of alloplastic breast reconstruction and conversion to autologous reconstruction. Methods: A retrospective chart review was conducted of patients who underwent mastectomy and immediate alloplastic breast reconstruction between 2008 and 2019. Inclusion criteria included patients 18 years or older who underwent initial alloplastic reconstruction with a minimum of 3-year follow-up...

Larva migrans is a cutaneous parasitic infection that occurs when an immature hookworm larva inadvertently penetrates the dermis of a human, typically on the extremities. Traditionally, a clinical diagnosis is made when a tortuous/serpiginous eruption is seen superficially in the skin with complaints of intense pruritus. Point of care ultrasound (POCUS) is a useful diagnostic tool for soft tissue complaints in the emergency department (ED). We describe a case of an 18-year-old woman who presented to the ED with foot pruritis four days after walking on the beach barefoot...

A 30-year-old man presented to otolaryngology department complaining of nasal congestion and runny nose for six months, with repeated fever, and shortness of breath.The weight loss in the past 20 days was about 5 kg. At first, he was diagnosed with respiratory infection and was treated with antibiotics, but it didn't work. Nasopharynx CT scan showed soft tissue thickening without bone destruction, with obvious inhomogeneous enhancement. Chest CT scan revealed multiple patchy clouding nodules and ground-glass opacity with poorly-defined border...

Information was obtained on personal history, antimicrobial therapy received, and clinical evolution...

BACKGROUND: Esthetic complications, such as capsular contracture and soft-tissue contour defects, hinder the desired outcomes of breast reconstruction. As subclinical infection is a prevailing theory behind capsular contracture, we investigated the effects of post-operative infections on these issues and revision procedures. METHODS: We conducted a retrospective database study (2007-2021) on breast reconstruction patients from the MarketScan® Databases. Esthetic complications were defined by their associated revision procedures and queried via CPT codes...

BACKGROUND: Uterine necrosis is a rare condition and is considered a life-threatening complication. However, cases of uterine necrosis were rarely reported, particularly those caused by infection. In terms of treatment, no minimally invasive treatment for uterine necrosis has been reported, and total hysterectomy is mostly considered as the treatment option. OBJECTIVE: The article specifically focuses on minimally invasive treatments and provides a summary of recent cases of uterine necrosis...

Group B Streptococcus (GBS; also known as Streptococcus agalactiae) is an opportunistic bacterial pathogen that causes sepsis, meningitis, pneumonia and skin and soft tissue infections in neonates and healthy or immunocompromised adults. GBS is well-adapted to survive in humans due to a plethora of virulence mechanisms that afford responses to support bacterial survival in dynamic host environments. These mechanisms and responses include counteraction of cell death from exposure to excess metal ions that can cause mismetallation and cytotoxicity, and strategies to combat molecules such as reactive oxygen and nitrogen species that are generated as part of innate host defence...
