Non-HACEK Gram-negative bacillus endocarditis.

PATIENTS AND METHODS: Retrospective analysis of clinical data using 26 diagnosed non-HACEK Gram-negative infective endocarditis cases from nine hospitals in Turkey. RESULTS: Mean age of patients was 53 (28-84) years, with a 23% case fatality. Nineteen (73%) of the 26 patients had at least one predisposing factor. The presence of a central venous catheter was the most common predisposing factor (7/26 patients). Pseudomonasaeruginosa (7/26 patients) and Escherichiacoli (7/26 patients) were the most common pathogens. The median duration of the antibiotic therapy was 42 days (range 3-84 days). Surgical procedures were performed in 10 patients. The case fatality was similar in patients who did or did not undergo surgery (20% vs. 25%).

Comparision of Ureteral Stent Colonization Between Deceased and Live Donor Renal Transplant Recipients.

BACKGROUND: The use of a ureteral stent can cause a urinary tract infection (UTI), although it reduces urologic complications. UTIs are associated with a higher rate of ureteral stent colonization (USC). The aim of this study was to compare USC in living and deceased donor renal transplant recipients. MATERIAL AND METHODS: We conducted a prospective study of 48 patients who underwent renal transplantation between January and December 2016. The stents were removed aseptically, the inner surface of proximal and distal ends of stents were irrigated with liquid culture medium, and then they were vortexed for bacteriological investigation. Urine cultures were taken at the same time. RESULTS: A total of 45 renal transplantation patients (21 from cadavers, 24 from live donors) were evaluated in the study. The duration time of stent retention in patients with live donors was 25.04 ± 4.55 and in patients with deceased donors was 26.19 ± 4.08 days (P = .376). USC was observed in 12 (57.1%) and 6 (25%) patients while positive urine culture (PUC) was detected in 5 (23.8%) and 2 (8.3%) patients in deceased and live donor transplant recipients, respectively. Although the USC rate was significantly higher in the deceased donor renal transplant group (P = .022), there was no significant different in the rates of PUC (P = .137). Enterecoccus species was the common pathogen isolated from ureteral stent and urine. The micro-organisms isolated from ureteral stent in deceased and live donors, respectively, were distributed as follows: Enterococcus 5/3, Candida 3/1, Escherichia coli 2/1, Klebsiella pneumonia 1/1, and staphylococci in 1/0 patients. All E coli and K pneumoniae are extended spectrum beta-lactamase (ESBL)-positive isolates and resistant to sulfamethoxazole-trimethoprim (SMX/TMP). CONCLUSIONS: We report a high incidence of USC in deceased renal transplants. Enterecoccus instead of E coli is the most common pathogen during the first month after transplantation. Transplantation centers should be aware that deceased donor renal transplant recipients are more prone to stent-related infection and the antibacterial resistance rapidly increases in uropathogens.

Acute Brucellosis Following Accidental Exposure to Brucella melitensis Rev 1 Vaccine.

Brucellosis is mainly transmitted to humans by direct contact with infected animals, consumption of non-pasteurized dairy products or through inhalation of aerosols. However, the disease may also be transmitted by exposure to Brucella vaccination that is used in veterinary medicine. In the literature, there were a few case reports of persons who developed brucellosis after unintentional inoculation or conjunctival exposure to the live Brucella vaccine. Here, we describe a sheep farmer with acute brucellosis that occurred as a result of unintentional percutaneous exposure to Brucella melitensis Rev 1 animal vaccine while vaccinating lambs.

Evaluation of tularaemia courses: a multicentre study from Turkey.

In this multicentre study, which is the largest case series ever reported, we aimed to describe the features of tularaemia to provide detailed information. We retrospectively included 1034 patients from 41 medical centres. Before the definite diagnosis of tularaemia, tonsillitis (n = 653, 63%) and/or pharyngitis (n = 146, 14%) were the most frequent preliminary diagnoses. The most frequent clinical presentations were oropharyngeal (n = 832, 85.3%), glandular (n = 136, 13.1%) and oculoglandular (n = 105, 10.1%) forms. In 987 patients (95.5%), the lymph nodes were reported to be enlarged, most frequently at the cervical chain jugular (n = 599, 58%), submandibular (n = 401, 39%), and periauricular (n = 55, 5%). Ultrasound imaging showed hyperechoic and hypoechoic patterns (59% and 25%, respectively). Granulomatous inflammation was the most frequent histological finding (56%). The patients were previously given antibiotics for 1176 episodes, mostly with ß-lactam/ß-lactamase inhibitors (n = 793, 76%). Antituberculosis medications were provided in seven (2%) cases. The patients were given rational antibiotics for tularaemia after the start of symptoms, with a mean of 26.8 ± 37.5 days. Treatment failure was considered to have occurred in 495 patients (48%). The most frequent reasons for failure were the production of suppuration in the lymph nodes after the start of treatment (n = 426, 86.1%), the formation of new lymphadenomegalies under treatment (n = 146, 29.5%), and persisting complaints despite 2 weeks of treatment (n = 77, 15.6%). Fine-needle aspiration was performed in 521 patients (50%) as the most frequent drainage method. In conclusion, tularaemia is a long-lasting but curable disease in this part of the world. However, the treatment strategy still needs optimization.
