Review
Chronic periodontitis is a ubiquitous inflammatory disease in dental healthcare that is challenging to treat due to its impact on bone and tooth loss. Conventional mechanical debridement has been challenging in eliminating complex subgingival biofilms. Hence, adjunctive approaches like low-level laser antimicrobial photodynamic therapy (A-PDT) utilising methylene blue (MB) have been emerging approaches in recent times. This review evaluates the latest research on the use of MB-mediated A-PDT to decrease microbial count and enhance clinical results in chronic periodontitis. Studies have shown the interaction between laser light and MB generates a phototoxic effect thereby, eliminating pathogenic bacteria within periodontal pockets. Moreover, numerous clinical trials have shown that A-PDT using MB can reduce probing depths, improve clinical attachment levels, and decrease bleeding during probing in comparison to traditional treatment approaches. Notably, A-PDT shows superior antibiotic resistance compared to conventional antibiotic treatments. In conclusion, the A-PDT using MB shows promise as an adjunctive treatment for chronic periodontitis. Additional research is required to standardize treatment protocols and assess long-term outcomes of A-PDT with MB in the treatment of periodontitis.

Deep sternal wound infection is a rare complication of cardiac surgery that is typically caused by skin resident flora, such as species of and . Infections caused by fungi are less common and are generally caused by species. Regardless of etiology, these infections are associated with significant morbidity and mortality. We present a case of postoperative mediastinitis that occurred following a 5-vessel coronary artery bypass graft and was caused by a filamentous fungus of the genus. The patient was treated with serial debridement, liposomal amphotericin B, and isavuconazonium and was discharged from the hospital in stable condition. Fungal mediastinitis is a rare entity, and clinicians must maintain a high level of suspicion to make the diagnosis. A fungal cause of postoperative mediastinitis should be considered in patients with negative bacterial cultures, uncontrolled diabetes, or current immunosuppression or those who present weeks after surgery with a subacute onset of symptoms.

Necrotizing fasciitis (NF) of the face is a rare yet serious condition requiring prompt and comprehensive management. This approach typically involves input from various medical specialties such as infectious disease specialists, critical care physicians, and surgeons. The primary goals are early recognition, aggressive surgical debridement, appropriate antibiotic therapy, and supportive care. Prompt diagnosis is crucial, based on symptoms like severe pain, rapidly spreading erythema, and systemic signs of infection. Broad-spectrum antibiotics are initiated empirically, and adjusted based on culture results. Urgent surgical debridement is crucial, removing all necrotic tissue. Careful consideration must be given to preserve vital structures. Close monitoring and intensive care may be necessary, especially for severe cases. Soft tissue reconstruction may follow once the infection is controlled, aiming to restore function and aesthetics. Long-term follow-up is essential to observe for complications and recurrence.

Variation in North American Infectious Disease Specialists' Practice Regarding Oral and Suppressive Antibiotics for Adult Osteoarticular Infections: Results of an Emerging Infections Network (EIN) Survey.
BACKGROUND
Osteoarticular infections (OAIs) are commonly treated with prolonged intravenous (IV) antimicrobials. The Oral versus Intravenous Antibiotics for Bone and Joint Infection (OVIVA) trial demonstrated that oral (PO) antibiotics are noninferior to IV antibiotics in the treatment of OAIs. We surveyed infectious disease (ID) physicians about their use of PO antibiotics in the treatment of OAIs.
METHODS
An Emerging Infection Network survey with 9 questions regarding antibiotic prescribing for the treatment of OAIs was sent to 1475 North American ID physicians. The questions were mostly multiple choice and focused on the use of definitive oral antibiotic therapy (defined as oral switch within 2 weeks of starting antibiotics) and chronic suppressive antibiotic therapy (SAT).
RESULTS
Of the 413 physicians who reported treating OAIs, 91% used oral antibiotics at least sometimes and 31% used them as definitive therapy, most often for diabetic foot osteomyelitis and native joint septic arthritis. The oral antibiotics most frequently used for OAIs included trimethoprim-sulfamethoxazole, doxycycline/minocycline, and linezolid for , amoxicillin/cefadroxil/cephalexin for streptococci, and fluoroquinolones for gram-negative organisms. The most common rationales for not transitioning to oral antibiotics included nonsusceptible pathogens, comorbidities preventing therapeutic drug levels, and concerns about adherence. SAT use was variable but employed by a majority in most cases of periprosthetic joint infection managed with debridement and implant retention.
CONCLUSIONS
North American ID physicians utilize oral antibiotics and SAT for the management of OAIs, although significant practice variation exists. Respondents voiced a need for updated guidelines.

BACKGROUND
Armed conflict injury is a growing public health concern, particularly in regions like the Middle East and North Africa (MENA). The protracted conflicts and political unrest in this region have led to a substantial number of injuries. Despite this, there is still limited understanding of the specific injury patterns stemming from conflicts, such as the 2006 Lebanon conflict. This study aimed to assess the characteristics and burdens of injuries resulting from this conflict, which occurred 16 years prior to this research.
METHODS
This retrospective study analyzed data of individuals affected by the 2006 Lebanon conflict, across three tertiary care centers. Demographics, injuries, complications, injury management, and hospitalization expenses were extracted from medical records and analyzed using SPSS version 29.0. Categorical variables were presented as counts and proportions, and continuous variables as mean ± standard deviation (SD). Hospital comparisons utilized chi-square or Fisher's exact tests for categorical variables, and one-way ANOVAs for continuous variables. Analysis was conducted from September to November 2023.
RESULTS
Across three hospitals, 341 patients were studied, comprising 73.6% males and 26.4% females. Among them, a notable proportion (57.3% males and 34.1% females) fell within the 18-39 age range. Children and adolescents under 18 years accounted for 15.9% of males and 25.9% of females. Blast-related injuries predominated, with 24.5% resulting from direct damage caused by explosive parts and 33.3% from blast wave forces. Extremity trauma occurred in 49.0% of patients, and head/neck trauma in 24.9%. Common injuries, including penetrating, musculoskeletal, and traumatic brain injuries affected 34.9%, 31.1, and 10.0% of patients, respectively. Wound repair, fracture treatment, and debridement were the most performed procedures on 15.5, 13.5 and 9.7% of the patients, respectively. The total cost of care was USD 692,711, largely covered by the Ministry of Public Health (95.9%).
CONCLUSION
Conflict-related injuries significantly contribute to the global burden of disease. Therefore, there is a pressing need to improve national guidelines to prioritize life-threatening cases and potential long-term disabilities. Furthermore, enhancing electronic registry systems to collect clinical data on injured patients is essential for conducting research and better understanding the needs of conflict casualties.

Necrotizing fasciitis, a rare, potentially life-threatening infection, often necessitates urgent medical intervention and surgical excision of the affected tissue. We present a 55-year-old male patient with a progressively enlarging lump in the left breast that was diagnosed as a breast carcinoma. Post-modified radical mastectomy, histopathological examination revealed Grade II invasive ductal carcinoma with neuroendocrine features. Due to financial constraints, the patient missed post-operative follow-ups and did not complete the prescribed radiotherapy sessions. Three months later, the patient returned with fever, swelling alongside sharp pain in the left arm and oozing blood. A clinical diagnosis of necrotizing fasciitis was made, leading to urgent surgical debridement. While the wound progressively healed, a contracture developed restricting elbow movement. An Orthopedic Review and Bone scintigraphy revealed metastasis of breast carcinoma to the sternum. This case report highlights the multi-disciplinary management required in such financially constrained rare cases in low- and middle-income countries.

BACKGROUND
This controlled experimental study aimed to compare ectopic replantation with other replantation techniques in a rat model of crush amputations. It also assessed the impact of different replantation methods on the viability of amputates.
METHODS
Forty male Wistar albino rats were divided into four groups. Groin flaps served as the amputation model. Group 1 un-derwent guillotine-style amputation followed by orthotopic replantation, Group 2 experienced crush-type amputation and orthotopic replantation, Group 3 had crush-type amputation and orthotopic replantation with a vein graft, and Group 4 underwent crush-type amputation followed by ectopic replantation. Flap viability and perfusion rates were assessed on day 3 using an infrared perfusion as-sessment system. The ratio of viable area to total flap area and thrombus formation in the pedicle vessels were evaluated on day 7.
RESULTS
Infrared evaluations on day 3 post-replantation revealed flap perfusion percentages of 73.5% in Group 1, 11.1% in Group 2, 65% in Group 3, and 64.1% in Group 4. Statistical analysis indicated that Group 1 exhibited the highest perfusion rates, while Group 2 showed the lowest. No differences were observed between Groups 3 and 4. On the seventh day, the average surviving flap areas were found to be 74.6% in Group 1, 2.5% in Group 2, 64.5% in Group 3, and 64% in Group 4. Statistically, Group 1 exhibited the best outcomes, while Group 2 had the poorest, with no differences between Groups 3 and 4. Additionally, thrombus formation was observed in the vessels of two animals in Group 1, nine in Group 2, and three each in Groups 3 and 4. Significant statistical differences were noted among the groups.
CONCLUSION
The results indicate that ectopic replantation and replantation with a vein graft are equally effective. The preferred method for crush-type replantations may depend on the patient's and the amputated limb's conditions. In crush-type amputations, we recommend vein graft repair if the patient's overall condition supports replantation and if crushed segments can be debrided without excessive shortening of the amputated part. If these conditions are not met, temporary ectopic replantation is advised to preserve the amputated limb.

Clinical Trial
BACKGROUND
Diabetic foot ulcers (DFUs) pose significant challenges for patients, often leading to chronic inflammation, reduced mobility, and chronic pain. Despite being less prevalent in the United States compared to other nations, the economic burden of DFUs remains substantial, with an estimated annual cost ranging from $9 billion to $13 billion. Furthermore, DFUs are a leading cause of nontraumatic lower extremity amputations and significantly impact health care systems and work productivity.
OBJECTIVE
This study aimed to evaluate the effectiveness of a polyvinyl alcohol (PVA) foam dressing containing gentian violet/methylene blue (GV/MB) in managing chronic DFUs.
MATERIALS AND METHODS
A single-center study was conducted involving 20 patients with full-thickness chronic lower extremity wounds, including DFUs. Patients received treatment with a PVA foam dressing with GV/MB applied in an outpatient setting over a period of 4 weeks. Wound size, bacterial presence, and healing progress were assessed using fluorescence imaging and wound measurements.
RESULTS
The study included 13 males and 7 females with an average age of 64.2 years. After 4 weeks of treatment, the average DFU size decreased by 53%, with 4 patients achieving complete wound closure. Reduction in ulcer size was strongly correlated with the use of surgical debridement and PVA GV/MB foam. Fluorescence imaging demonstrated a significant reduction in bacterial presence in all patients by the end of the study. Follow-up at 3 and 6 months showed no recurrent ulcerations, indicating the potential for long-term efficacy.
CONCLUSION
The findings suggest that PVA GV/MB foam dressings, when combined with surgical debridement, are effective in promoting the healing of chronic DFUs. Further research with larger, controlled studies is warranted to confirm these findings and assess cost-effectiveness.

BACKGROUND
The use of negative pressure wound therapy with instillation and dwell time (NPWTi-d) has been shown to be effective in removing nonviable tissue, reducing bioburden, and promoting granulation tissue formation in acute and chronic infected wounds.
OBJECTIVE
To illustrate the clinical efficacy of the use of pure hypochlorous acid (pHA) antimicrobially preserved wound cleansing solution as the instillation fluid for NPWTi-d (NPWTi-d/pHA) in wound bed preparation in patients with complex wounds.
CASE REPORT
The treatment protocol for use of NPWTi-d/pHA in preparing wound beds for final closure is demonstrated in 3 illustrative cases of patients with complex wounds resulting from necrotizing infection and trauma with heavy contamination. All 3 patients developed a healthy-appearing wound bed deemed suitable for primary closure an average of approximately 1 month following initial surgical debridement.
CONCLUSION
The cases presented demonstrate the ability of a pHA antimicrobially preserved wound cleansing solution used as the instillation fluid with NPWTi-d to aid in bacterial reduction, mechanical debridement, and promotion of wound healing. Use of NPWTi-d/pHA in these cases of extensive necrotizing infection and posttraumatic injury with heavy contamination allowed for final closure an average of 1 month after initial surgical debridement.
