RESUMO
BACKGROUND: Despite contributing to significant morbidity in working-age adults, there is no consensus on the optimal treatment for prepatellar bursitis. Much of the existing literature combines prepatellar and olecranon bursitis. This systematic review aims to determine the optimal management of prepatellar bursitis. STUDY DESIGN AND METHODS: A primary search of electronic published and unpublished literature databases from inception to November 2019 was completed. Articles over 25 years old, case reports with less than four patients, paediatric studies, and non-English language papers were excluded. Our primary outcome was recurrence after 1 year. Comparisons included endoscopic vs open bursectomy, duration of antibiotics. Methodological quality was assessed using the Institute of Health Economics and Revised Cochrane Risk of Bias scoring systems. Meta-analyses were conducted where appropriate. RESULTS: In total 10 studies were included (N = 702). Endoscopic and open bursectomy showed no difference in recurrence after 1 year (OR 0.41, 95% CI 0.05-3.53, p = 0.67), and surgical complications (OR 1.44, 95% CI 0.34-6.08, p = 0.44). 80% endoscopically-treated patients were pain free after 1 year. Patients treated with antibiotics for less than 8 days were not significantly more prone to recurrence (2/17 vs 10/114, OR 0.66, 95% CI 0.13-3.29, p = 0.64) compared to 8 days plus at minimum 1 year post injury. CONCLUSIONS: Our study represents the largest cohort of patients evaluating management strategies for prepatellar bursitis, and includes data not previously published. Endoscopic bursectomy is non-inferior to open bursectomy, enabling a shorter hospital stay. It also offers a relatively low risk of post-operative pain. Endoscopic bursectomy is a viable option to treat both septic and aseptic prepatellar bursitis. Our small cohort suggests recurrence and hospital stay are not improved with antibiotic treatment exceeding 7 days for septic prepatellar bursitis.

BACKGROUND: Umbilical vein bacterial infections may cause liver abscesses during bacterial ascent. A single liver abscess can be surgically treated by marsupialization, but a risk of recurrence or non-healing remains. Moreover, there is no effective treatment for multiple abscesses. CASE PRESENTATION: A 17-day-old Holstein female calf exhibited reduced general condition, swelling and drainage of the umbilicus, and pressure sores in the area of the carpus, resulting in reluctance to stand up. The umbilicus showed pain at palpation; deep abdominal palpation indicated a swollen umbilical vein coursing from the umbilicus toward the liver. Ultrasonography confirmed a swollen umbilical vein with pus accumulation and multiple abscesses in the liver. Contrast-enhanced computed tomography (CT) examination confirmed that the swollen umbilical vein with fluid continued to the liver, and multiple unenhanced lesions, most likely abscesses, were confirmed in the liver. Partial hepatectomy was performed to remove as many abscesses as possible. For the resection, a vessel sealing device (LigaSureTM) was used to excise a part of the left liver lobe. As we could not remove all the abscesses in the liver during the operation, cefazolin sodium (5 mg/kg) was administered for 14 days after surgery. Post-operatively, blood accumulation was observed in the abdominal cavity, but no signs of peritonitis were found. The calf returned to the farm on day 38 after surgery. Follow-up information was obtained after 1 year, and complications were not reported. CONCLUSIONS: To our knowledge, this is the first report of partial hepatectomy using a vessel sealing device for a calf with multiple liver abscesses. This case report suggests that the combination of partial hepatectomy and long-term administration of antibacterial drugs may restore the health of calves with multiple liver abscesses.

Chronic, severe otitis media was diagnosed in four Atlantic harbor seals (Phoca vitulina concolor), three of which were stranded animals undergoing rehabilitation. All seals presented with unilateral purulent aural discharge that would intermittently recur despite prolonged topical and systemic antimicrobial therapy. Aerobic culture from aural discharge isolated multidrug-resistant organisms in all seals, including Pseudomonas aeruginosa, Staphylococcus pseudintermedius, Klebsiella pneumoniae, and/or Enterococcus faecalis. Computed tomography was used in three cases to confirm otitis media and positive contrast ear canalography was used in one case to confirm tympanic membrane rupture. Given the persistent nature of otitis, surgical intervention in the form of a total ear canal ablation and lateral bulla osteotomy (TECA-LBO) was indicated. Surgery was successful in achieving complete clinical resolution of otitis in all seals. Postoperative complications included temporary unilateral paralysis of the left nare (2/4) and a transient left ptosis (1/4). Partial to complete surgical site dehiscence occurred in all cases; however, complete healing was achieved by second intention in 60 d or less. One rehabilitated seal was fitted with a satellite tag that confirmed normal swimming and diving patterns post release. In harbor seals, TECA-LBO can be performed safely to treat persistent cases of otitis media and should be considered in cases of chronic otitis that are not responsive to medical management.

As antimicrobial resistance increases, it is crucial to develop new treatment strategies to counter the emerging threat. In this paper, we consider combination therapies involving conventional antibiotics and debridement, coupled with a novel anti-adhesion therapy, and their use in the treatment of antimicrobial resistant burn wound infections. Our models predict that anti-adhesion-antibiotic-debridement combination therapies can eliminate a bacterial infection in cases where each treatment in isolation would fail. Antibiotics are assumed to have a bactericidal mode of action, killing bacteria, while debridement involves physically cleaning a wound (e.g. with a cloth); removing free bacteria. Anti-adhesion therapy can take a number of forms. Here we consider adhesion inhibitors consisting of polystyrene microbeads chemically coupled to a protein known as multivalent adhesion molecule 7, an adhesin which mediates the initial stages of attachment of many bacterial species to host cells. Adhesion inhibitors competitively inhibit bacteria from binding to host cells, thus rendering them susceptible to removal through debridement. An ordinary differential equation model is developed and the antibiotic-related parameters are fitted against new in vitro data gathered for the present study. The model is used to predict treatment outcomes and to suggest optimal treatment strategies. Our model predicts that anti-adhesion and antibiotic therapies will combine synergistically, producing a combined effect which is often greater than the sum of their individual effects, and that anti-adhesion-antibiotic-debridement combination therapy will be more effective than any of the treatment strategies used in isolation. Further, the use of inhibitors significantly reduces the minimum dose of antibiotics required to eliminate an infection, reducing the chances that bacteria will develop increased resistance. Lastly, we use our model to suggest treatment regimens capable of eliminating bacterial infections within clinically relevant timescales.

PURPOSE OF REVIEW: Biofilm-associated infections cause difficulties in the management of childhood chronic infections and other diseases, due to the invasive nature of interventions which are often necessary for definitive management. Despite their importance, there are challenges in diagnosing biofilm infections and gaps in clinicians' understanding regarding the significance of biofilms. RECENT FINDINGS: Many chronic infections associated with biofilms remain difficult or impossible to eradicate with conventional therapy. Surgical intervention, implant removal or long-term intermittent or suppressive antimicrobial therapy may be required. There are still significant challenges in detecting biofilms which presents a barrier in clinical practice and research. Novel therapies to disrupt biofilms are currently under investigation, which may help reduce the impact of antimicrobial resistance. SUMMARY: Biofilm-associated infection should be considered wherever there is clinical concern for an infection affecting prosthetic material, where there is a predisposing condition such as suppurative lung disease; or in the setting of chronic or relapsing infections which may be culture negative. New diagnostic methods for detecting biofilms are a research priority for both clinical diagnosis and the ability to conduct high quality clinical trials of novel antibiofilm interventions.

PURPOSE: Controversy exists over whether bacterial flora within the appendix differs between patients with and without appendicitis. To examine these potential differences, we cultured the appendiceal luminal microbiota of patients with and without acute appendicitis, and identified the bacterial species therein. METHODS: Fifty-seven patients with acute appendicitis and 37 patients without acute appendicitis who underwent curative resection of colorectal cancer and prophylactic appendectomies (control group) were included. Appendicitis patients were classified into the phlegmonous group or the gangrenous appendicitis group histopathologically. There was no patient with perforated appendicitis. Aerobic isolates were identified using standard identification schemata, and anaerobic isolates were identified according to the Japanese guidelines. RESULTS: There were no significant differences among the three groups in the median number aerobe species present per patient. However, the median number anaerobe species in the gangrenous appendicitis group was significantly higher than that of the control group and the phlegmonous appendicitis group. In addition, the incidence of patients with Bacillus species, Fusobacterium nucleatum, and Bilophila wadsworthia increased as the disease progressed from phlegmonous to gangrenous appendicitis. CONCLUSION: The present results suggest that increased diversity of anaerobes and the translocation of Bacillus species, F. nucleatum, and B. wadsworthia are associated with the progression of acute appendicitis.

Culture-independent studies have identified DNA of bacterial pathogens in the gallbladder under pathological conditions, yet reports on the isolation of corresponding live bacteria are rare. Thus, it is unclear which pathogens, or pathogen communities, can colonize the gallbladder and cause disease. Using light microscopy, scanning electron microscopy, culture techniques, phylogenetic analysis, urease assays and Western blotting, we investigated the presence of live bacterial communities in the gallbladder of a cholecystitis patient after cholecystectomy. 16S rRNA gene sequencing of isolated bacterial colonies revealed the presence of pathogens most closely resembling Corynebacterium urinapleomorphum nov. sp., Staphylococcus saprophyticus and Helicobacter pylori. The latter colonies were confirmed as H. pylori by immunohistochemistry and biochemical methods. H. pylori cultured from the gallbladder exhibited both the same DNA fingerprinting and Western cagA gene sequence with ABC-type EPIYA (Glu-Pro-Ile-Tyr-Ala) phosphorylation motifs as isolates recovered from the gastric mucus of the same patient, suggesting that gastric H. pylori can also colonize other organs in the human body. Taken together, here we report, for the first time, the identification and characterization of a community consisting of live S. saprophyticus; C. urinapleomorphum, and H. pylori in the gallbladder of a patient with acute cholecystitis. Their potential infection routes and roles in pathogenesis are discussed.

The management of infected pancreatic necrosis has historically been based on early, open necrosectomy, associated with significant mortality. In recent years, an evidence based transformation has occurred towards the step-up approach consisting of percutaneous catheter drainage, if necessary, followed by minimally invasive necrosectomy. More recently the endoscopic step-up approach has gained popularity. This review evaluates the diagnosis, prevention and treatment of infected necrotizing pancreatitis. Key points in managing infected pancreatic necrosis: - multidisciplinary team approach in tertiary level centres; - no indication for prophylactic antibiotics or probiotics; - nasogastric, enteral nutrition indicated after 72 hours, if oral feeding is insufficient; - only intervene in infected necrosis; - delay intervention until "walled-off necrosis"; - step-up approach of percutaneous or endoscopic catheter drainage, followed by minimally invasive necrosectomy, if required; - endoscopic strategies are preferable where possible.

PURPOSE: The clinical term "prostatitis" refers to a clinical syndrome defined by the following 4 distinct entities: acute bacterial prostatitis (category 1), chronic bacterial prostatitis (category 2), chronic prostatitis/chronic pelvic pain syndrome (category 3), and asymptomatic prostatitis (category 4) The etiology of the chronic forms is still not fully understood and choice of therapy is often debated. The objective of this systematic review is to collect evidence on the surgical treatment of the chronic form of prostatitis and to evaluate its clinical implication. METHODS: We performed a systematic literature search and identified 6683 relevant publications, of which 16 were included in the review. RESULTS: Transurethral prostate resection was performed in 110 patients; 78 patients (70%) were reported as "cured", 16 patients (15%) as improved, and 16 patients (15%) as unchanged. Radical prostatectomy was performed in 21 patients; a full resolution of prostatitis related symptoms was reported for 20 patients (95%). No increased rates of complications or unusual complications were noted. CONCLUSIONS: Surgical therapy of chronic bacterial prostatitis or chronic pelvic pain syndrome might be a viable option; however, since little evidence is currently available and no randomized controlled trials have been conducted, the presently available data does not provide a base for clinical decisions.

BACKGROUND: Spontaneous bacterial peritonitis (SBP) is a common infection in cirrhosis associated with high mortality. More than 20% of patients with SBP do not respond to initial antibiotics. Guidelines differ in recommendations to repeat paracentesis (retap) to confirm antibiotic efficacy. We aim to evaluate the effect of retap-guided management of SBP on antibiotic escalation and 30-day transplant-free survival. MATERIALS AND METHODS: Retrospective cohort study of cirrhotic patients with SBP admitted to a single transplant center from 2010 to 2014. Patients were divided into 2 groups: retap-guided management versus no retap. Prevalence of initial antibiotic treatment failure, defined as <25% decrease in ascitic polymorphonuclear cells, and factors associated with treatment failure, antibiotic escalation and 30-day transplant-free survival were evaluated. RESULTS: Out of 210 patients, 146 (age 58, 74% male, mean model for end-stage liver disease score, 25) had retap and treatment failure was noted in 28 (22%). Gram-positive bacteria accounted for 44% of all positive cultures and third-generation cepahalosporin resistance was noted in 23%. Thirty-day transplant-free survival was 72% and 62% in retap and control groups, respectively (P=0.07). Treatment failure independently doubled the 30-day mortality rate (hazard ratio: 2.15, 1.03 to 4.50, P=0.04). After adjusting for age, model for end-stage liver disease and nosocomial infection, retap-guided management was not associated with improved survival (P=0.34). CONCLUSIONS: The prevalence of initial treatment failure is high (22%) in patients with SBP and doubles the 30-day mortality risk, supporting recommendations to retap all patients with SBP.

PURPOSE: Bacterial infections are a factor for morbidity in patients with acute appendicitis (AA). The spreading of multidrug-resistant (MDR) bacteria is a significant problem in surgery, and the most relevant MDR pathogens are summarized as Enterobacteriaceae, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterococci (ESKAPE) bacteria. Data regarding the species and distribution of bacteria in AA are available, but information about the resistances and their relevance is deficient. METHODS: In this retrospective study, we analyzed microbiological swabs of patients with AA. The outcome parameters of patients after laparoscopic appendectomy were analyzed against microbiological results, including antibiotic resistance testing. Positive swabs were compared with bacteria cultivated after alternative abdominal emergency surgery (AES). RESULTS: In total, 584 patients with AA were included and had a mean age of 35.5 years. In 216 patients (36.9%), a swab was taken, and in 128 (59.3%) swabs, bacteria could be cultivated. The most frequent organisms were Escherichia coli, Bacteroides species, and Pseudomonas. In 9.4% of the positive AA swabs, MDR germs were cultivated, and all of them were ESKAPE pathogens. Patients with MDR bacteria in AA suffered more infectious complications (p = 0.006) and needed longer hospitalizations (p < 0.009). In AES, aside from appendicitis, a different spectrum containing more MDR bacteria was cultivated (5.9 vs. 20.9%; p < 0.0001). CONCLUSIONS: Although they occur less frequently in appendectomy compared to emergency surgeries for other abdominal diseases, MDR bacteria are traceable in this common disease and contribute to additional morbidity.

The aim of this study is to evaluate the clinical and microbiological effect of the systemic antibiotic therapy of proanthocyanidins and secnidazole on periodontitis. Seventy-five subjects with chronic periodontitis were randomly divided into two treatment groups (secnidazole or proanthocyanidins) and one placebo control group (25 cases each). Plaque index (PI), gingival index (GI), gingival bleeding index (BI), probing pocket depth (PPD), and clinical attachment level (CAL) were carried out at baseline, post-treatment and 3 months after treatment. Microbial analysis was performed at baseline and post-treatment. The results show that the two treatment groups had greater mean reduction in BI, GI, and PPD evaluated at both post-treatment and 3 months after treatment compared to the control group (p less than 0.05), but there were no significant differences in those of PI and CAL (except CAL evaluated at post-treatment, p 0.05). After treatment, culturable bacteria counts significantly decreased. In conclusion, the adjunctive use of proanthocyanidins or secnidazole in combination with scaling and root planing in adults with periodontitis is effective in reducing the pathogenic flora and achieves significantly better clinical results to a certain degree.

OBJECTIVE: To report the short- and long-term outcomes of surgical management of umbilical infection in foals. STUDY DESIGN: Retrospective case series. ANIMALS: Foals (n = 65). METHODS: Medical records (2010-2015) of foals up to 1 month of age, surgically treated for an umbilical infection were reviewed. Short-term (at the time of discharge from hospital) and long-term (1 year after surgery) survival rates were obtained. Clinical variables influencing survival were assessed. Chi-square or Fisher's exact test were used to evaluate the relationship between the data retrieved and outcome. P ≤ .05 was considered statistically significant. RESULTS: Sixty-five foals were included in the study, representing 17.2% of all foals admitted to the hospital. Fifty foals were discharged from hospital (77%) and 43 foals (66%) were alive 1 year after surgery. Lower long-term survival rates were associated with: younger age at presentation, septic joints, multiple pathologies, higher creatinine level, higher heart rate, umbilical infection diagnosed at the hospital rather than prior to referral, prolonged hospitalization, longer period between arrival and surgery, and postoperative complications. The most common surgical findings were urachal enlargement followed by right arterial enlargement. CONCLUSION: Younger foals with worse systemic condition and concurrent disorders are at higher risk for treatment failure. Early diagnosis improves the outcome. Surgical treatment yields good results and should be considered upon diagnosis, after taking into account the clinical situation. CLINICAL SIGNIFICANCE: Based on the results of this study, diagnosis and surgical management of umbilical infection in neonatal foals should be performed as early as possible, and a good outcome can be expected after surgery.

Inflammatory markers are essential tools in the decision-making process for lower extremity infections. When coupled with objective findings, clinicians can more accurately diagnose and treat these entities. Typically, markers such as the white blood cell count, erythrocyte sedimentation rate, and C-reactive protein are used to initially assess these patients or monitor the progression of medical or surgical therapy. Procalcitonin is a newer inflammatory marker that is specific for an infectious process. Originally, procalcitonin was used to monitor antibiotic therapy and sepsis for patients in the intensive care setting, but it has now been expanded to other facets of medicine. The utility of procalcitonin has been described for diagnosing infection or osteomyelitis in diabetic foot ulcers. However, limited research has compared inflammatory marker levels and the level of amputation. A retrospective inpatient medical record review was performed of 156 consecutive patient occurrences during 25 months in which surgical intervention was required for a lower extremity infection and an initial procalcitonin level had been obtained. This initial procalcitonin value was then compared with the level of amputation at the final surgical intervention. A highly statistically significant difference was found when comparing those who underwent a below-the-knee or above-the-knee amputation (median procalcitonin 1.72 ng/mL) and those who did not (median procalcitonin 0.105 ng/mL; p < .001). Therefore, patients with higher initial procalcitonin values were more likely to undergo below-the-knee or above-the-knee amputation or require aggressive surgical intervention. Thus, the procalcitonin level can provide valuable initial information to the clinician.

Hip disarticulation is a major ablative procedure with serious risks as well as consequences for the patient, performed rarely for a lower extremity infection. According to literature, the mortality rate in these procedures reaches up to 60%. Unfavourable prognostic factors are emergency surgeries without adequate preparation of the patient and surgeries indicated for an ischemic terrain infection. The authors present four cases of hip disarticulation for severe lower extremity infection. In one patient, the procedure was performed urgently for necrotising fasciitis in the lower extremity extending up to the groin area, in the other three patients for non-healing femoral stump infection following the lower extremity amputation for vascular causes, of which two cases got complicated by the presence of TKA. Two of the patients treated surgically for stump infection died two months after the surgery due to respiratory complications. The two surviving patients underwent the last check one year following the surgery, they are both capable of independent locomotion with two underarm crutches and use the prosthesis only rarely. In the discussion, the factors influencing the mortality rate of the procedure, the principles of surgical and antimicrobial therapy, and the use of the negative-pressure wound therapy are analysed. The underlying principles of the care for patients with severe infections of the musculoskeletal system are infection focus debridement with the removal of foreign material, antibiotic (anti-infective) therapy targeted based on the cultivation results, wound management aimed to prevent contamination with nosocomial strains, and multidisciplinary cooperation - orthopaedist/surgeon, infectious disease physician, intensive care specialist, nutrition and rehabilitation specialist, nursing and prosthetic care providers. Key words: hip disarticulation, infection, necrotizing fasciitis.

The purpose of this investigation was to evaluate the patient characteristics, clinical manifestations, microbiology, and modes of treatment of a large cohort of women with acute Bartholin's abscess, from a single medical center. A retrospective study was undertaken of all women diagnosed with acute Bartholin's gland abscess who were admitted to the gynecology department in a university-affiliated tertiary hospital in central Israel from January 2004 to December 2013. A total of 267 women were included in the study. The mean age at diagnosis was 33.5 ± 12.1 years and the mean hospitalization period was 1.4 ± 0.9 days. Pain presented in 152 (56.9 %), swelling in 81 (30.3 %), and fever in 34 (12.7 %). Leukocytosis was detected in 149 (55.8 %). The three main treatment modalities were: antibiotics (75.7 %), abscess drainage (19.1 %), and marsupialization (80.9 %). Bacterial infections were detected in 154 (57.7 %) cultures, Escherichia coli presented in 59 (22.1 %), and Streptococcus species in 27 (10.1 %). The clinical and patient characteristics were similar between women with bacterial and sterile Bartholin's abscesses, though leukocytosis was more prevalent among women with bacterial infections. E. coli was the single most frequent pathogen in cultures of acute Bartholin's abscess. Respiratory tract-associated organisms were also common. This study indicates the polymicrobial spectrum of acute Bartholin's abscess.

PURPOSE: The purpose of this study is to report the results of a series of infected forearm nonunions treated from 1998 to 2012 using a staged reconstruction technique. METHODS: At a median of 42 months follow-up, 7 patients who had an average segmental defect of 4.9 cm (range, 2.3-10.4 cm) were available for clinical and radiographic evaluation. Treatment consisted of serial debridement, implantation of an antibiotic cement spacer, and staged reconstruction using a bulk radius or ulna allograft with intramedullary fixation. RESULTS: All 7 patients ultimately achieved solid bone union, although 4 patients (57%) required additional surgery, consisting of autologous bone grafting and plating, to achieve healing at 1 of the allograft-host junction sites. No patient had recurrence of infection, and all reported substantial improvement with increased function and decreased pain. CONCLUSIONS: Our approach ultimately resulted in a 100% union rate without recurrence of infection, although many patients may require additional surgery to attain healing at both allograft-junction sites.

Radiotherapy is mandatory for aggressive cancer treatment. Unfortunately, the high-energy radiation used can lead to severe osteoradionecrosis. Radical debridement of devitalized bone and soft tissue coupled with reconstruction using well-vascularized tissues is the accepted treatment for this condition. However, osteoradionecrosis cannot be controlled easily or rapidly. The aim of this study was to present the results of the use of serial negative-pressure wound therapy (NPWT) in combination with a latissimus dorsi myocutaneous flap for treatment of gluteal osteoradionecrosis in a consecutive series of patients. Between January 2003 and December 2012, nine patients underwent reconstruction using serial NPWT and latissimus dorsi myocutaneous flaps. We applied negative-pressure dressings for at least 8 weeks. Final reconstruction was performed after the infection was controlled. The superior gluteal artery and vein were used as recipient vessels in all the cases. The mean interval between operation and radiation therapy was 28.3 ± 8.3 years, and the mean number of debridement performed was 6.3 ± 1. NPWT dressings were applied for 8-12 weeks (mean, 9.3 ± 2 weeks). The defects ranged in size from 14 × 8 cm to 18 × 15 cm. The flap size ranged from 15 × 10 cm to 18 × 15 cm. All flaps survived uneventfully except in one patient who experienced chronic seroma and wound dehiscence. There were no recurrences of osteomyelitis during the follow-up periods (mean, 14 ± 6.1 months). Based on the results obtained from this consecutive series of patients, we suggest that this methodology may provide an alternative approach for the treatment of severe osteoradionecrosis of the gluteal region.

BACKGROUND: The surgical treatment of pleural empyema should be carried out depending on the stage of the disease and the patient's symptoms. The aim of this study was to evaluate the outcomes of surgical pleural empyema treatment. PATIENTS AND METHODS: Retrospective analysis of all patients with pleural empyema treated surgically between January 2008 and December 2013. The primary endpoint of the study was inpatient lethality. Secondary endpoints included duration of inpatient stay, type of treatment (surgical/conservative), proof of pathogen and type, alteration and duration of antibiotic therapy. RESULTS: Of 359 patients, 0.8â% (n = 3) had stage I empyema, 50.4â% (n = 181) had stage II and 48.7â% (n = 175) had stage III. The most frequent causes (32.4â%) included acute pneumonia (parapneumonic pleural empyema), surgery (usually thoracic) in 18.0â% of cases and previous pneumonia (postpneumonic pleural empyema) in 15.4â%. Surgery was performed in 86â% of cases (operative procedures: open thoracotomy 85â%, VATS 15â%). The average duration of inpatient stay was 20 days for stages II and III. Recovery following VATS was significantly shorter in stage II compared to thoracotomy (p = 0.022). Hospital lethality amounted to 7.0â% (25 patients). The lethality rate was 5.5â% (10/185) in stage II and 8.6â% (15/175) in stage III. Patients with confirmed pathogens had a significantly worse mortality rate across all stages (9.8â%) than patients with no confirmed pathogens (4.0â%, p = 0.034). Age, malignant underlying disease, multiple comorbidities, immunosuppression, a change in antibiotic regimens and sepsis were significant risk factors. CONCLUSION: The inpatient lethality of patients with pleural empyema correlates with the stage of the condition. Positive confirmation of pathogens, sepsis, a higher age, multiple comorbidities, malignant tumour disease, immunosuppression and a change of antibiotics are negative prognostic factors.

OBJECTIVES: Current guidelines tell us that intervention in severe necrotizing pancreatitis ought to be performed as late as possible. However, when pancreatic necrosis becomes infected, the necrotic tissue needs to be removed. Unfortunately, bacterial infection can only be proven by invasive methods. METHODS: Necrotizing pancreatitis with sterile or infected necrosis was induced in mice. Mice serum samples were examined by antibody-based protein array. After identifying candidate proteins that showed strong regulation, the serum concentration of these proteins was examined by sandwich ELISA. Then, human serum samples were collected from patients with mild pancreatitis, severe pancreatitis with and without pancreatic necrosis and patients with microbiologically proven infection of pancreatic necrosis. These serum samples were then analyzed by sandwich ELISA. RESULTS: In mice 6 proteins were strongly up-regulated and were further investigated by ELISAs. Of these proteins, CXCL16 and TRANCE (RANKL) concentrations were analyzed in human serum samples. CXCL16 and TRANCE were increased in patients with pancreatic necrosis and abdominal infection. Receiver operated characteristics showed that CXCL16 was superior in predicting infected pancreatic necrosis when compared to C-reactive protein and TRANCE. CONCLUSIONS: Serum CXCL16 is increased in severe pancreatitis with infected pancreatic necrosis and identifies patients who benefit from surgical necrosectomy.
