Review
Periprosthetic joint infection (PJI) is a catastrophic complication following joint replacement surgery, posing significant challenges to orthopedic surgeons. Due to the lack of a definitive diagnostic gold standard, timely treatment initiation is problematic, resulting in substantial economic burdens on patients and society. In this review, we thoroughly analyze the complexities of PJI and emphasize the importance of accurate diagnosis and effective treatment. The article specifically focuses on the advancements in diagnostic techniques, ranging from traditional pathogen culture to advanced molecular diagnostics, and discusses their role in enhancing diagnostic accuracy. Additionally, we review the latest surgical management strategies, including everything from debridement to revision surgeries. Our summary aims to provide practical information for the diagnosis and treatment of PJI and encourages further research to improve diagnostic accuracy and treatment outcomes.

Prolonged fever for more than a week or fever of unknown origin in pediatric patients with or without soft tissue infection should raise suspicion for infection. A 10-year-old female presented to urgent care with a "bug bite" on the left ring finger, cough, and 2 to 3 days of low-grade fever. Ten days later, her symptoms progressed to soft tissue swelling of the left elbow without fracture on radiograph. Magnetic resonance imaging revealed multiple reniform masses with avid contrast enhancement consistent with suppurative adenitis. She was admitted for irrigation and debridement. The patient underwent surgical debridement with removal of infected lymph nodes. Histology revealed necrotizing granulomatous lymphadenitis. Polymerase chain reaction was positive for . Antibody titer revealed immunoglobulin G titer of 1:512 (reference, 1:64), and negative immunoglobulin M titers were indicative of mature immune response. The patient was treated with azithromycin 250 mg tablets twice daily for 3 days followed by 3 days of the 250 mg tablet once daily. Follow-up showed resolution of infection without symptoms concerning for visceral organ infection. While the patient's initial presentation was vague, a complete history, quick follow-up, and decisive intervention prevented significant sequelae such as visceral organ involvement.

INTRODUCTION
Tuberculosis (TB) is one of the most prevalent infectious diseases globally, often presenting with nonspecific symptoms that can obscure diagnosis, especially when it manifests in uncommon sites such as osteoarticular tuberculosis (OA-TB).
CASE PRESENTATION
We report a rare case of a 9-year-old male diagnosed with right knee tuberculosis after enduring severe symptoms for several months. Despite multiple negative biopsies and aspirates during initial debridement surgeries, a biopsy taken 6 months later confirmed the presence of (MTB). The patient was subsequently treated with debridement and anti-tubercular therapy.
CONCLUSION
This case underscores the critical need to consider tuberculosis in patients presenting with chronic bone pain to avoid misdiagnosis, particularly in the developing world. The atypical presentation of osteoarticular tuberculosis in this young patient emphasizes the need for healthcare professionals to recognize subtle symptoms. Advanced imaging studies like MRI and microbiological evaluations, including site biopsies, are essential for accurate diagnosis. Increased awareness and collaborative research are crucial to improving the understanding and management of pediatric osteoarticular tuberculosis and extrapulmonary tuberculosis.

BACKGROUND
Breast reconstruction following mastectomy is a critical component of breast cancer treatment, aimed at improving patient quality of life. However, the management is fraught with potential complications, including skin necrosis and wound dehiscence, which can significantly impact clinical outcomes.
CASE PRESENTATION
We report a unique case of a patient, 5 years post-breast reconstruction following mastectomy and radiation therapy, who developed severe skin necrosis and wound dehiscence due to a brown recluse spider bite on the reconstructed breast. The complication necessitated the debridement of skin, removal of the implant, and further reconstruction with a latissimus flap.
DISCUSSION
The case underscores the unusual etiology of spider bite-induced necrosis in breast reconstruction and highlights the challenges and strategic considerations in managing such complications. Upon presentation, the patient's affected breast area showed signs of extensive necrosis and wound dehiscence, directly attributed to the cytotoxic effects of the brown recluse spider's venom. The venom's pathophysiology involves a complex cascade, leading to local and systemic effects. The local effects, marked by dermonecrosis, com- promised skin integrity in this instance. Systemic effects, not observed in this patient but potentially severe, can include hemolysis, coagulopathy, and acute renal failure, highlighting the seriousness of brown recluse spider bites.
CONCLUSION
In conclusion, this case illustrates the complexities of managing breast reconstruction post-mastectomy complications, particularly those caused by external factors such as brown recluse spider bites. It highlights the need for meticulous attention to unusual etiologies of necrosis and dehiscence, demonstrating the importance of adaptable surgical strategies and a thorough understanding of venom pathophysiology in ensuring successful patient outcomes.

Western armies have relied on surgical field manuals to help physicians deal with unfamiliar combat medical conditions from the Napoleonic wars to the present day, but there has been little discussion of whether these handbooks have been used or improved outcomes. Recent research shows that the Union Army's American Civil War (1861-1865) surgical case fatality rates improved as the war progressed, much like the US Army's experience in later wars, and were generally superior to comparable European results. These positive Civil War outcomes have been attributed to field experience, adoption of best practices, and enhanced communication, without consideration of New York surgeon Stephen Smith's widely-used . The Army of the Potomac added Smith's pocket-sized to its supply table in 1862. Northern medical journals applauded it, and Smith's contemporaries documented its wide use. Smith's handbook explained and demonstrated surgical techniques that were adopted as the war progressed, such as the use of general anesthesia and limb-sparing resection (debridement) of gunshot wounds. It offered pithy, well-documented advice from recognized experts along with numerous illustrations, which allowed untrained physicians to visualize anatomical relationships and see contemporary best practices in a way that no other wartime publication provided, making it an exemplar of a mass-media surgical improvement change agent.

Penile strangulation secondary to utilization of a constrictive ring is a rare urologic emergency that requires urgent decompression to prevent prolonged vascular obstruction resulting in necrosis and gangrene. Current literature is mainly comprised of case presentations that focus on management in the acute setting via removal of the ring. Herein, we describe surgical management of a patient who presents in delayed fashion after self-removal of the constrictive ring. We discuss our penectomy-sparing technique of debridement and split thickness skin graft.

INTRODUCTION
Cryptococccus neoformans is a fungus which typically presents in immunocompromised hosts, commonly presenting as meningoencephalitis. There have been very few documented incidents of intramuscular manifestations of this pathogen.
CASE REPORT
We report on a case of a 45-year-old caucasian male with disseminated Cryptococcus neoformans who developed cryptococcal intramuscular abscesses of all extremities and osteomyelitis of the left upper limb. Clinical treatment and surgical debridement of the forearm was performed. Persistent infection resulted in a left humeral amputation and ultimately the patient's death. This is one of the few documented intramuscular abscesses of Cryptococcus neoformans.
CONCLUSION
Orthopedic manifestations of cryptococcal infections are rare; however, awareness and prompt diagnosis may improve outcomes.

Increased CD56 expression after photodynamic therapy indicates an increased natural killer cell count following early photodynamic therapy for cutaneous squamous cell carcinoma.
Cutaneous squamous cell carcinoma (cSCC) is the second most common type of skin cancer. Photodynamic therapy (PDT) is a promising therapeutic method for managing cSCC due to its proven ability to target specific areas over time and its low risk of side effects. PDT may cause tissue damage and vascular shutdown, and may regulate local immunological responses. The present study aimed to investigate and compare the early lymphocyte modifications before and after PDT for SCC. A total of 10 patients with SCC were identified by pathological investigation. Initially, all wounds were treated with 20% aminolevulinic acid (ALA)-PDT as the initial stage in the therapeutic procedure. The wounds were treated by exposing them to red LED light with a wavelength of 635 nm, an energy density of 100 J/cm and an intensity of 80 mW/cm. The tumor tissue was surgically removed 24 h later, and another round of PDT therapy was administered. Immunohistochemistry for CD3 and CD56 was conducted on the wound tissue post-surgery. If the wound showed granulation, necrosis or secretion, debridement was added to the therapy. All patients were monitored for 0.6-1.0 year post-treatment. ALA-PDT combination surgery fully controlled the tumor tissue in all 10 patients. The immunohistochemical analysis of the wound tissues showed that the expression of CD56 increased, while the expression of CD3 was not different after photodynamic therapy. These results also indirectly indicated that the overall count of NK cells in the 10 patients increased, nevertheless, there was no alteration in the T lymphocyte count. In conclusion, the ALA-PDT combination surgical therapy for cSCC demonstrates favorable results. An increase in CD56 expression may be a mechanism for the effective treatment of cSCC with PDT.

BACKGROUND
Open, grossly contaminated femoral shaft fractures pose a significant threat for fracture-related infection. Traditional treatment for these injuries consists of irrigation and debridement with temporizing external fixation placement and staged conversion to definitive fixation.
METHODS
We describe a protocol for acute antibiotic cement nailing of open femoral shaft fractures as an infection prophylaxis modality in fractures with a high risk of infection and present three cases.
RESULTS
Three patients presented with open femoral shaft fractures with large soft tissue defects and gross contamination and were successfully treated with acute retrograde antibiotic nailing and external fixation with later conversion to definitive metallic nailing. They did not develop infection and had acceptable postoperative function and fracture alignment.
CONCLUSION
This technique of early infection prophylaxis after open femoral shaft fracture is reproducible, pragmatic, and cost-effective.

Necrotizing fasciitis (NF) poses a diagnostic challenge due to its rarity and similarity in presentation with other critical conditions. We report a case of a 79-year-old male who initially presented with altered mental status and stroke-like symptoms; he was ultimately diagnosed with abdominal wall NF spreading to the lower extremity. Despite a history of cecal mass perforation noted in prior imaging, the patient had been discharged from an outside emergency room on antibiotics, highlighting a missed opportunity for early intervention. Subsequent deterioration led to sepsis, organ failure, and ultimately, the detection of NF. Prompt recognition of subtle skin changes and laboratory abnormalities, along with a detailed physical examination, is essential for a timely and accurate diagnosis. Surgical debridement, coupled with broad-spectrum antibiotics, remains the cornerstone of treatment. Delays in surgical management significantly increase mortality, emphasizing the importance of prompt diagnosis and intervention. This case underscores the necessity for heightened awareness among healthcare providers to recognize NF promptly, especially when its clinical presentation overlaps with other critical conditions. Multidisciplinary collaboration and continued education are imperative to improve outcomes and prevent delays in the diagnosis and treatment of NF.
