Fournier Gangrene as a Complication of a Perinephric Abscess After Kidney Transplant: A Case Report.

Fournier gangrene is a progressive necrotizing infection of the external genitalia or perineum that constitutes a urologic emergency. Incidence of Fournier gangrene is rising because of population aging, increasing comorbidities, and widespread use of immunosuppressive therapy, including immunosuppressive regimens used in kidney transplants. This is a rapidly progressive and potentially lethal disease without treatment, and early recognition of the disease, proper management of the predisposing factors, and aggressive surgical debridement are the most essential interventions. We report a rare case of Fournier gangrene in the early postoperative period of a kidney transplant due to a perinephric abscess.

Rare case of perforated appendicitis presenting as persistent perineal discharge following laparoscopic abdominoperinal excision of rectum (APER).

Abdominoperineal excision of rectum (APER) is one of the widely used surgical procedures to treat low rectal cancer, benign conditions like Crohn's proctitis with anal involvement and as a salvage procedure for anal cancer. Perineal wound infection is a well-recognised complication following such major surgery. Occurrence of appendicitis in a few weeks' time following such a major surgery is uncommon. However, here we present a rare case report of perforated appendicitis presenting as persistent perineal discharge in an elderly man, following laparoscopic APER for a low rectal tumour. To our knowledge, this is the first time such a rare clinical presentation of appendicitis is reported in the history of medical literature. Through this case report, we aim to highlight the importance of considering such an uncommon presentation in patients with perineal discharge, following APER.

Comparative Evaluation of Translocation of GFP Producing Escherichia coli Strains in Acute Intestinal Obstruction.

Comparative evaluation of translocation of E. coli GFP-producing strains in experimental rats with obturation and strangulated intestinal obstruction was carried out. Translocation of infused GFP-producing E. coli strain was studied by bacteriological methods in male rats with experimental obturation and strangulated intestinal obstruction with various ischemia/reperfusion cycles. The maximum incidence of translocation in obturation intestinal obstruction was observed after 24 h. In strangulated intestinal obstruction, the highest incidence was recorded in ischemia/reperfusion cycles of 1 h/2 h and 2 h/6 h. No appreciable differences in the incidence of translocation in animals with two types of intestinal obstruction were detected.

The pathogens and curative effects analysis of perianal abscess of infants under 3 months.

Zhu Y, Xu F. The pathogens and curative effects analysis of perianal abscess of infants under 3 months. Turk J Pediatr 2019; 61: 40-43. In order to guide clinical treatment for perianal abscess of young infants, the characteristics of pathogens and curative effects analysis were conducted. Bacterial culture results, antibiotics susceptibility tests and curative effects of abscess incision were retrospectively analyzed in 66 cases of perianal abscess of infants under 3 months. There were 48 cases of Klebsiella pneumoniae, 7 cases of Staphylococcus, 6 cases of Escherichia coli, 5 cases of Proteus in the pathogen culture results. Klebsiella pneumoniae, the predominant pathogen, was susceptible to most antibiotics, especially to imipenem, cefoperazonesulbactam and amikacin with low drug resistance rates. However, high drug resistance rates were found to ampicillin and nitrofurantion. After abscess incision, the complication rate of anal fistula was 6.6％ in infants under 3 months and 60.3％ in the adult group. There was significant difference P＜0.01. In conclusion, Klebsiella pneumoniae was the most common pathogen in perianal abscess of infants under 3 months and was commonly resistant to ampicillin and nitrofurantion. Since perianal abscess of infants under 3 months is a self-limited disorder, simple surgical intervention and synchronous sensitive antibiotic administration are suggested as the optimal management.

Infected Abdominal Aortic Aneurysm After Transrectal Ultrasound-Guided Biopsy of the Prostate: A Report of Two Cases.

Primary infected abdominal aortic aneurysm (AAA) is an uncommon presentation which can be associated with significant morbidity and mortality. In this report, we present 2 cases of infected AAAs less than 10 days after a transrectal ultrasound-guided (TRUS) prostate biopsy. A 63-year-old male presenting with sepsis and back pain 9 days after TRUS biopsy was found to have a 27-mm ectatic abdominal aorta which expanded to 59 mm in the course of a week, despite antibiotic therapy. He underwent successful surgical excision of the infected aortic aneurysm and reconstruction using a vein. A 55-year-old male presented similarly, 7 days after prostate biopsy with a 60-mm aortic aneurysm. His aneurysm ruptured 2 days before planned intervention-he did not survive an emergency repair. In both cases, aortic tissue biopsies confirmed growth of Escherichia coli. Preexistence of an aortic aneurysm was not known in either case as neither patient had imaging of the abdominal aorta. We postulate the pathophysiology was due to hematogenous spread.

Spinal Intradural Escherichia coli Abscess Masquerading as a Neoplasm in a Pediatric Patient with History of Neonatal E. coli Meningitis: A Case Report and Literature Review.

BACKGROUND: Central nervous system abscesses frequently can be seen in the immunocompromised population and most commonly consist of intracranial collections in the adult patient. Spinal intradural abscesses are less commonly encountered, and there are even fewer numbers in the pediatric population with a concordant absence of documentation in the published literature. CASE DESCRIPTION: In this case report, we describe the presentation of a 2-year-old boy with a history of perinatal Escherichia coli meningitis at 2.5 months of age who was found to have an intradural spinal lesion, initially concerning for neoplasm, but later confirmed as an E. coli abscess following biopsy. He was managed with surgical aspiration of the abscess and a long course of intravenous antibiotics. The patient was treated with antibiotics with repeat imaging studies that revealed residual abscess that required re-aspiration at a later date. CONCLUSIONS: Here we present an unusual disease process with an unusual disease pathogenesis in a pediatric patient currently residing in a developed country.

Tunneled Pleural Catheters for Patients With Chronic Pleural Infection and Nonexpandable Lung.

Chronic pleural infection is characterized by thickened pleura and nonexpandable lung often requiring definitive surgical intervention, such as decortication and/or pleural obliteration procedures. Such procedures are associated with significant morbidity and require proper patient selection for a successful outcome. We report a cohort of 11 patients with pleural space infection and a nonexpandable lung treated with tunneled pleural catheters (TPCs). Following placement, hospital discharge and TPC removal occurred after a median of 5 and 36 days, respectively. Three patients presented with residual loculated effusion that resolved with instillation of intrapleural fibrinolytic therapy. One patient eventually required open window thoracostomy for ongoing pleural infection due to poor medical compliance with TPC care and drainage instructions. TPCs represent an alternative option for drainage of an infected pleural space in nonsurgical candidates with a nonexpandable lung. Their use, as a compliment to traditional treatment, may facilitate prompt hospital discharge and ambulatory management in patients with limited life expectancy.

Treatment-refractory Escherichia coli subdural empyema caused by infection of a chronic subdural hematoma in an infant.

INTRODUCTION: Subdural empyema (SDE) is a neurosurgical emergency that is typically treated with surgical drainage, either by burr hole or by craniotomy. Escherichia coli is an uncommon cause of SDE and is associated with infection of a pre-existing subdural hematoma. CASE REPORT: We report the case of an otherwise healthy, immunocompetent 4-month-old infant girl with an E. coli-infected subdural hematoma. The infection persisted despite aggressive neurosurgical treatment that included drainage of the subdural space through burr holes and, subsequently, a wide craniotomy was performed. Ultimately, after 30 days, the SDE resolved with good neurological outcome. A review of prior literature indicates that infected subdural hematomas (including those caused by E. coli) are typically less aggressive and respond to burr hole drainage. CONCLUSION: We illustrate the fulminant progression of the SDE in the face of neurosurgical treatment. Our experience suggests lowering the threshold for wide craniotomy in these incompletely understood cases.

Pyogenic Spondylodiscitis of the Thoracic Spine: Outcome of 1-Stage Posterior Versus 2-Stage Posterior and Anterior Spinal Reconstruction in Adults.

OBJECTIVE: The aim of this study was to compare the clinical, radiologic, and functional outcomes of a 1-stage posterior treatment versus a 2-stage posterior-anterior treatment in patients with pyogenic thoracic spondylodiscitis. METHODS: A 1-stage posterior debridement, stabilization, and fusion with titanium-coated polyetheretherketone (PEEK) or mesh cage through a dorsolateral approach was performed in group A. A 2-stage procedure with initial posterior stabilization and debridement and second-stage fusion with a PEEK cage or mesh cage was performed with an anterior approach in group B. Clinical outcomes included Oswestry Low Back Pain Disability Questionnaire and visual analog scale score. Radiologic outcomes included fusion rate and kyphotic angle correction. Secondary variables included pathogens, complications, blood loss, and operative time. RESULTS: One-level spondylodiscitis was treated surgically in the thoracic spine of 47 patients: 25 patients in group A and 22 patients in group B. The most frequent segment was T12-L1 (27%). There was a significantly longer operative time and greater blood loss (P > 0.001) in group B. At last follow-up, sagittal profile reconstruction was significantly better (P > 0.05) in group B. Both groups showed similar radiologic results with fusion in 92% of cases. Improved clinical outcomes, pain, and quality of life were achieved in both groups with no significant differences between the 2 groups. CONCLUSIONS: Better reconstruction of the sagittal profile was achieved in the posterior-anterior-treated group, but this did not affect the clinical outcome. No significant differences were found in the clinical and functional outcomes between the 2 groups. Posterior-anterior combined treatment should be considered in cases of large anterior defects if a posterior reconstruction is inadequate.

Clinical predictors of escalating care in hepatic and renal cyst infection in autosomal dominant polycystic kidney and liver disease.

BACKGROUND: Cyst infection may occur in autosomal dominant polycystic kidney disease (ADPKD) and autosomal dominant polycystic liver disease (ADPLD). Antimicrobial agents often fail to control infection, leading to invasive action. We aimed to identify factors predicting escalation of care. METHODS: ADPKD and ADPLD patients were identified from local/national databases (2001-2013). Records were screened for patients meeting criteria for cyst infection (positive cyst aspirate and/or clinical findings). Factors that predict escalated care were identified with multivariate modified Poisson regression. RESULTS: We screened 1773 patients. A total of 77 patients with cyst infection (4.3%) were included for analysis (hepatic 36%; male 49%; age 54 ±; 13 years; ADPKD 95%; dialysis 9%, diabetes 18%, renal transplant 56%, eGFR [IQR 24-78] ml/min/1.73 m2 (excluding patients with a history of renal transplant or receiving dialysis)). A pathogen was identified in 71% of cases. Escherichia coli was the most common pathogen and accounted for 69% of cases. Initial treatment was limited to antibiotics in 87% of patients (n = 67), 40% included a fluoroquinolone. Ultimately, 48% of patients underwent some form of invasive action (escalation of care). Increasing white blood cell count (WBC) (RR 1.04 95%-CI 1.01-1.07, p = 0.008) was associated with escalating care, whereas an increase in time between transplant and infection (RR 0.92 95% CI 0.86-0.97, p = 0.005) and E. coli isolation (RR 0.55 95% CI 0.34-0.89, p = 0.02) were protective. CONCLUSION: High serum WBC, isolation of atypical pathogens and early infection after transplantation are factors that increase the risk of escalation of care in hepatic and renal cyst infection patients.

[FOUR CASES OF THE PROSTATIC ABSCESS IN WHICH DRAINAGE WAS EFFECTIVE].

We encountered four prostatic abscess patients. Although antimicrobial therapies were ineffective, drainage was effective in all cases. Patient 1 had lung cancer and diabetes mellitus (DM), and patient 2 developed acute prostatitis after transrectal prostatic biopsy. Culture of the urine and blood revealed extended-spectrum beta lactamase (ESBL) -producing Escherichia coli (E.coli). Patient 3 had previously sustained spinal cord injury, and urinated by self-catheterization. Patient 4 had untreated, severe DM. Patient 1, 2 and 3 had been treated by transurethral resection of the prostate (TURP). Patient 2 complained of ejaculatory incompetence after the surgery, and the symptom caused mental distress. Patient 4 was a 43-year-old man who had undergone transperineal needle aspiration under ultrasound guidance to avoid ejaculatory incompetence. The prostatic abscess disappeared in all cases after drainage without recurrence.

[Retropharyngeal abscess with cervical discitis and vertebral osteomyelitis caused by Escherichia coli in a patient with liver cirrhosis].

We describe the case of a 67-year-old male with liver cirrhosis who presented with fever and neck pain. Magnetic resonance imaging of the spine detected cervical vertebral osteomyelitis, and enhanced CT of the neck and spine revealed retropharyngeal abscess. The patient was treated with empirical antimicrobial therapy and surgical drainage due to significant airway involvement. Escherichia coli was cultured from the blood and pus in inferior cervical vertebrae which was a rare pathogen. Haematogenous spread may have resulted in cervical vertebral osteomyelitis and retropharyngeal abscess. With high mortality rates, early diagnosis of retropharyngeal abscess is required to avoid debilitating complications such as airway obstruction.

[COMPARATIVE ESTIMATION OF THE APPLICATION EFFICACY FOR THE COMPOSITION, BASING ON NANODISPERSE SILICA, OWING ANTIMICROBIAL PROPERTIES FOR LOCAL TREATMENT OF PURULENT-INFLAMMATORY PROCESSES].

Comparative estimation of the local treatment results for purulent-inflammatory diseases of soft tissues, using standard methods and composition, owing sorption and antimicrobial properties and basing on a nanodispersedsilica, was conducted. The composition application in complex of treatment have promoted more rapid clearance from necrotized tissues and microorganisms, rapid appearance of granulations, the intoxication severity reduction, the phase I of the wound process duration shortening, what have permitted to put secondary sutures on the wound on the 6 ­ 7th postoperative day, and total duration of the patients' stationary treatment have reduced by 3.7 days.

[APPLICATION OF VACUUM-THERAPY ON STAGES OF SURGICAL TREATMENT OF THE DIABETIC FOOT SYNDROME].

Vacuum therapy of an acute and chronic wounds was used in a complex of surgical treatment of 228 patients, suffering diabetic foot syndrome. There was established a positive local and systemic action of this method for the treatment of the wound defect. Vacuum therapy of the wounds guarantees the wound process clinical course stabilization, improvement of microcirculation, reduction of their microbial soiling, stimulation of regenerative processes, elimination of endogenous intoxication.

Feasibility of radiofrequency ablation as an alternative to surgical intervention in patients with huge multiloculated pyogenic liver abscesses: A retrospective cohort study.

This retrospective cohort study investigated the feasibility of radiofrequency (RF) ablation as an alternative to surgical intervention in patients with huge multiloculated pyogenic liver abscesses (PLAs).From August 2010 to April 2016, 83 patients with PLA were admitted to Beijing Chao-Yang Hospital, China. Four of these patients had huge multiloculated PLAs and underwent RF ablation plus antibiotics. The inclusion criteria for RF ablation were as follows: multiloculated PLA confirmed by computed tomography (CT) or magnetic resonance imaging (MRI), widest diameter of the PLA ≥5 cm, failure to respond to or not suitable to treatment with percutaneous drainage (PD), and patient refusal of surgery. The safety and effectiveness of RF ablation were initially assessed. All patients were commenced on antibiotics on admission to our hospital. CT-guided percutaneous catheter drainage was attempted in one patient but was unsuccessful. The main organism isolated from cultures of these patients' blood or abscess samples was Klebsiella pneumoniae (3/4). RF ablation was performed as soon as eligibility according to the above criteria was established.RF ablation was technically successful in all 4 study patients, all PLAs being completely eradicated. The median duration of fever after RF ablation was 4.5 days. No abscesses recurred; thus, this strategy for managing PLA was 100% successful (4/4). No procedure-related deaths or major complications occurred. One patient had an asymptomatic right pleural effusion that resolved with conservative treatment including albumin infusion and diuretics.Our preliminary data indicate that RF ablation is a safe, feasible, and effective treatment for huge multiloculated PLAs. It should be considered as an alternative treatment for patients who fail to respond to or not suitable for PD plus antibiotics and refuse surgical intervention.
