Surgical site infections (SSIs) following major lower limb amputation (MLLA) in vascular patients are a major source of morbidity. The objective of this systematic review was to determine the incidence of SSI following MLLA in vascular patients. This review was prospectively registered with the International Prospective Register of Systematic Reviews (CRD42023460645). Databases were searched without date restriction using a pre-defined search strategy. The search identified 1427 articles. Four RCTs and 21 observational studies, reporting on 50 370 MLLAs, were included. Overall SSI incidence per MLLA incision was 7.2% (3628/50370). The incidence of SSI in patients undergoing through-knee amputation (12.9%) and below-knee amputation (7.5%) was higher than the incidence of SSI in patients undergoing above-knee amputation, (3.9%), p < 0.001. The incidence of SSI in studies focusing on patients with peripheral arterial disease (PAD), diabetes or including patients with both was 8.9%, 6.8% and 7.2%, respectively. SSI is a common complication following MLLA in vascular patients. There is a higher incidence of SSI associated with more distal amputation levels. The reported SSI incidence is similar between patients with underlying PAD and diabetes. Further studies are needed to understand the exact incidence of SSI in vascular patients and the factors which influence this.

UNASSIGNED: Operations for malignant diseases of the bile duct, pancreas, and esophagus are the most invasive gastroenterological surgeries. The frequency of complications after these surgeries is high, which affects the postoperative course and mortality. In patients who undergo these types of surgeries, continuous monitoring of the perioperative central venous oxygen saturation (ScvO2) is possible via a central venous catheter. We aimed to investigate the relationship between continuously monitored perioperative ScvO2 values and postoperative complications.
UNASSIGNED: The medical records of 115 patients who underwent highly invasive gastroenterological surgeries and ScvO2 monitoring from April 2012 to March 2014 were analyzed. Sixty patients met the inclusion criteria, and their ScvO2 levels were continuously monitored perioperatively. The relationship between ScvO2 levels and major postoperative complications, defined as Clavien-Dindo grade ≥ III, was examined using uni- and multivariate analysis.
UNASSIGNED: Thirty patients developed major postoperative complications. The adequate cut-off value derived from receiver operating curves of the postoperative average ScvO2 levels for predicting major complications was 75%. Multivariate analysis revealed that low average postoperative ScvO2 levels (p = 0.016) and blood loss ≥ 1000 mL (p = 0.039) were significant predictors of major postoperative complications.
UNASSIGNED: Low perioperative ScvO2 values were associated with an increased risk of major postoperative complications. Continuous ScvO2 monitoring will help prevent postoperative complications.

UNASSIGNED: Patients requiring surgery for secondary peritonitis demonstrate a significantly increased risk for incisional surgical site infection. This study aimed to evaluate the efficacy of subcutaneous wound drain post-laparotomy for contaminated surgical wounds.
UNASSIGNED: This was a prospective comparative hospital-based study.
UNASSIGNED: Patients who had surgery for secondary peritonitis in Irrua Specialist Teaching Hospital were studied.
UNASSIGNED: Fifty patients aged 16 years and above who presented with secondary peritonitis.
UNASSIGNED: Patients who met the inclusion criteria were randomized into two equal groups. Group A had a suction drain placed in the subcutaneous space after laparotomy while Group B did not.
UNASSIGNED: Development of incisional surgical site infection, wound dehiscence, and duration of post-operative hospital stay.
UNASSIGNED: The incidence of incisional surgical site infection was significantly less in Group A (20%) than in Group B (68%). There was no case of wound dehiscence in Group A as against 3 (12%) in Group B. The difference was not statistically significant. The mean duration of hospital stay was significantly less with subcutaneous suction drain (8.96+2.81 Vs 14.04+8.05; p = 0.005).
UNASSIGNED: Subcutaneous suction drainage is beneficial in abdominal wall closure in cases of peritonitis as it significantly reduces the incidence of incisional surgical site infection and the duration of postoperative hospital stay. The reduction in surgical wound dehiscence observed in this study was, however, not statistically significant.
UNASSIGNED: None declared.

We present a case report about a 26-year-old female with a Mycobacterium wolinskyi surgical site infection after bilateral breast augmentation. In a unique approach compared with previously reported cases, the patient was successfully treated in an outpatient setting using only orally administered cotrimoxazole (trimethoprim-sulfamethoxazole) and ciprofloxacin with one-sided preservation of the breast prothesis. We also provide a comprehensive overview of all report cases of M. wolinskyi infections available in the PubMed database until December 2023 and compare the different diagnostic and therapeutic approaches.

BACKGROUND: Open long bone fractures are a major concern for pediatric patients due to the risk of surgical site infection (SSI). Early studies have recommended irrigation and debridement of open fractures within 6 hours-8 hours for the prevention of SSI. According to the American College of Surgeons (ACS) Best Practice Guidelines, in 2015, irrigation and debridement should be done within 24 hours.
OBJECTIVE: To identify whether early irrigation and debridement, within 8 hours, vs late, between 8 hours and 24 hours, for pediatric open long bone fractures impacts rate of SSI.
METHODS: Using retrospective data review from the National Trauma Data Bank, Trauma Quality Improvement Project (TQIP) of 2019. TQIP database is own by the ACS and it is the largest database for trauma quality program in the world. Propensity matching analysis was performed for the study.
RESULTS: There were 390 pediatric patients with open long bone fractures who were included in the study. After completing propensity score matching, we had 176 patients in each category, irrigation and debridement within 8 hours and irrigation and debridement between 8 hours and 24 hours. We found no significant differences between each group for the rate of deep SSI which was 0.6% for patients who received surgical irrigation and debridement within 8 hours and 1.1% for those who received it after 8 hours [adjusted odd ratio (AOR): 0.5, 95%CI: 0.268-30.909, P > 0.99]. For the secondary outcomes studied, in terms of length of hospital stay, patients who received irrigation and debridement within 8 hours stayed for an average of 3.5 days, and those who received it after 8 hours stayed for an average of 3 days, with no significant difference found, and there were also no significant differences found between the discharge dispositions of the patients.
CONCLUSIONS: Our findings support the recommendation for managing open long bone fractures from the ACS: Complete surgical irrigation and debridement within 24 hours.

This report highlights two cases of surgical site infections (SSIs) caused by Mycobacterium fortuitum (Mf) following abdominal mesh implantation. The first case involved an 83-year-old male experiencing non-healing erythema and wounds post-operation, which persisted despite multiple treatments, until effective management was achieved with targeted antibiotics after Mf identification. The second case concerned a female patient with a gynecological postoperative hernia, where Mf was quickly detected following SSI onset three weeks after surgery. Prompt mesh removal and appropriate antibiotic treatment led to a rapid and full recovery. These cases emphasize the importance of early detection and intervention in managing Mf infections effectively, illustrating how the timing of diagnosis can significantly influence treatment outcomes.

UNASSIGNED: Accurate identification of the etiology of orthopedic infection is very important for correct and timely clinical management, but it has been poorly studied. In the current study we explored the association of multiple bacterial pathogens with orthopedic infection.
UNASSIGNED: Hospitalized orthopedic patients were enrolled in a rural hospital in Qingdao, China. Wound or exudate swab samples were collected and tested for twelve bacterial pathogens with both culture and multiplex real time PCR.
UNASSIGNED: A total of 349 hospitalized orthopedic patients were enrolled including 193 cases presenting infection manifestations upon admission and 156 with no sign of infection. Orthopedic infection patients were mainly male (72.5%) with more lengthy hospital stay (median 15 days). At least one pathogen was detected in 42.5% (82/193) of patients with infection while 7.1% (11/156) in the patients without infection (P < 0.001). S. aureus was the most prevalent causative pathogen (15.5%). Quantity dependent pathogen association with infection was observed, particularly for P. aeruginosa and K. pneumoniae, possibly indicating subclinical infection. Most of the patients with detected pathogens had a previous history of orthopedic surgery (odds ratio 2.8, P = 0.038). Pathogen specific clinical manifestations were characterized. Multiplex qPCR, because of its high sensitivity, superior specificity, and powerful quantification could be utilized in combination with culture to guide antimicrobial therapy and track the progression of orthopedic infection during treatment.

Ramakrishna Pai JakribettuBackground  Surgical site infections (SSIs) in head and neck cancer (HNC) patients can significantly affect the outcome of the surgery. Appropriate antimicrobial prophylaxis is needed for prevention of SSI. Aim  To study the causative agents causing SSI among the HNC patients and their drug resistance pattern. Materials and Methods  This was a retrospective study. The antibiotic suspectibility pattern of the aerobic bacteria isolated from the wound infection in the patients underwent surgery for head and neck cancer, admitted from January 2015 to December 2016 were added in the study. The demographic details of patients, pathogens isolated, and their antimicrobial susceptibility were collected, entered into Microsoft Excel, and statistical analysis was done as per percentage of isolates and drug resistance. Results  A total of 130 culture-positive pus samples were included in the study. The majority of the samples were from males (71.5%), one-third of the patients belonged to the sixth decade of their life. Buccal mucosa and tongue were the common cancer in the head and neck region. The common gram-negative pathogens were Klebsiella sp. and Acinetobacter sp. and Staphylococcus aureus and Enterococcus sp. among the gram-positive bacteria. Methicillin-resistant S. aureus isolation rate was noted to be as high as 64.28%. High levels of resistance to aminopenicillins, third generation cephalosporins, co-trimoxazole and fluoroquinolones among the gram-negative pathogens. Anti-MRSA drugs such as vancomycin, linezolid, and teicoplanin resistance was not seen among S. aureus . Conclusion  The resistance pattern among the pathogens isolated from SSI in HNC patients is alarming. So, implementation of strict infection control practices to prevent SSI rather than treating them with high end antimicrobials is the best option.

The association of Staphylococcus aureus with vasculitis remains relatively rare and poorly understood. In this report, we present a case of Methicillin-sensitive Staphylococcus aureus (MSSA)-associated leukocytoclastic vasculitis (LCV) following a surgical site infection, adding to the limited body of knowledge on this intriguing clinical entity. A 52-year-old male with a medical history significant for type 2 diabetes mellitus, hypertension, hyperlipidemia, and coronary artery disease presented with progressively worsening generalized petechial rash and migratory joint pains with associated joint swelling. The patient\'s symptoms began following surgical repair for a rectus abdominis incisional hernia with mesh placement that was complicated by an abdominal wall abscess at the surgical site, prompting drain placement. Cultures from the abscess aspirate revealed Methicillin-sensitive Staphylococcus aureus infection. A punch biopsy of the petechial lesions revealed findings consistent with leukocytoclastic vasculitis. The rash and joint pains resolved approximately one week after initiation of treatment with antibiotics and steroids. This case sheds light on the rare but clinically significant association between Methicillin-sensitive Staphylococcus aureus infection and leukocytoclastic vasculitis, particularly following surgical site infections. The prompt recognition and treatment of underlying MSSA infection, along with the targeted management of LCV, resulted in the resolution of symptoms in our patient. This case emphasizes the importance of a comprehensive diagnostic approach and highlights the efficacy of antibiotic therapy in mitigating MSSA-associated vasculitic manifestations.

BACKGROUND: As surgery is an essential aspect of healthcare around the globe, it is necessary to consider complications related to it. Therefore, this study was conducted to evaluate the impact of the World Health Organization Surgical Safety Checklist (WHO SSC) on reducing the incidence of postoperative complications Methods: This single-center, prospective, comparative study was conducted at the Department of Gynecology and Obstetrics in a government hospital in Patna, Bihar. To assess the efficacy of the WHO SSC, the patients were divided into two groups, in which one group undergoing surgery was assessed with the checklist, and the other group was not. The rates of surgery-related complications were then compared in both groups.
RESULTS: Our results showed a reduction in surgery-related complications in patients assessed with the WHO SSC. No statistically significant difference in duration of surgery was found between the groups. However, a statistically significant difference was observed in the rates of surgery-related complications between groups, especially in sepsis (p=0.0009), hemorrhage (p<0.0001), and infection at the site of surgery (p<0.0001). Mortality rates were not affected by the use of the SSC.
CONCLUSIONS: The WHO SSC is a simple yet effective tool for reducing postoperative complications by improving communication between the various team members working in the operation theatre, although it has no effect on reducing mortality. Further research is needed to enhance its successful implementation and ensure its sustained use.
