Abstract Background Aerococcus urinae is a Gram-positive coccus that is increasingly recognized as a urinary pathogen since the introduction of mass spectrometry for identification of bacteria. We report a case of abdominal aortitis (with aneurysm) caused by A urinae in a male with recurrent urinary tract infections and recently treated A urinae bacteremia. A 63-year-old gentleman with a history of A urinae urosepsis 7 weeks prior, presented to the Emergency Department with thoracolumbar back pain radiating bilaterally into the groin. Radiological and surgical findings were consistent with infective infrarenal aortitis with aneurysm. Methods The patient successfully underwent open surgical debridement and reconstruction of the infrarenal aorta with autologous vein graft. Results Aerococcus urinae was isolated from excised tissue. The patient completed a 4-week course of intravenous antimicrobial therapy. Conclusions Aurinae is a urinary pathogen with the ability to cause severe invasive disease including endovascular infections.

Abstract. Background: Surgical revascularization for chronic critical limb ischaemia in patients with thromboangiitis obliterans (TAO) still remains controversial. Generally, besides cessation of smoking, conservative treatment supported by intravenous administration of vasoactive agents is regarded as the treatment of choice, in combination with local wound therapy or minor amputation. Patients and methods: In four male patients (42-47 years) surgical revascularization was chosen as therapy for established gangrene or non-healing ulceration after unsuccessful conservative treatment and cessation of smoking. Angiography was able to identify a suitable distal arterial segment for the bypass which was revascularized by means of an autologous vein graft. Grafts were followed with repetitive duplex ultrasound. Revision of the bypass graft was initiated if indicated by pathological duplex findings. Results: In all cases a bypass could be constructed with either the ipsilateral greater saphenous vein or arm veins. A distal origin configuration was possible in three cases with popliteo-pedal or cruro-pedal bypasses. In the fourth case the distal superficial femoral artery was used for inflow. Two early graft thromboses underwent successful revision. During follow-up, duplex ultrasound identified graft stenoses in three bypasses which were successfully treated with endovascular techniques. All grafts are patent with complete resolution of ischaemic symptoms after 46, 42, 32, and 29 months. The patients remained non-smokers and returned to a professional life. Conclusions: Surgical therapy with distal vein bypass for persistent ischaemic symptoms after definitive cessation of smoking seems feasible in selected cases with TAO and a suitable distal artery. Close follow-ups of the patients with duplex ultrasound are necessary to identify developing vein graft stenoses. Angioplasty seems to be an important part of the long-term therapeutic concept.

Introduction: Epididymo-orchitis is a common urological disease among men. Little is known about the clinical and epidemiological aspects of the disease in Iran. Thus, the present study was aimed to investigate the etiology, clinical sequelae and risk factors of patients with epididymo-orchitis in Tehran, Iran. Materials and Methods: Patients presenting with epididymo-orchitis were prospectively analyzed in order to study the etiology and pattern of the disease. Bacteriological, molecular and serological tests were undertaken to look for Chlamydia trachomatis, Neisseria gonorrhoeae, Brucella spp., Mycoplasma spp, and other bacteria. Results: Fifty patients with epididymo-orchitis were evaluated according to their clinical symptoms, duration of symptoms, physical examination, and laboratory studies. The mean age of the patients was 53 years. Fever, dysuria, pain in the flanks, urinary frequency and discharges occurred in 58.0%, 50.0%, 50.0%, 28.0% and 6.0%, respectively. Bacterial pathogen was identified in 26% (13/50) of patients by urine culture. Escherichia coli was the etiological agent in 11/13 patients (84.6%). Two out of 50 patients (4.0%) were also positive for Chlamydia trachomatis. Two samples were serologically positive for Brucella spp. High Mean age, fever, urinary frequency, history of the underlying disease and history of urinary tract infections were found to have a significant association with the positive bacteriologic urine culture (P<0.05). Conclusions: The most common clinical manifestations were fever, dysuria, and abdominal pain. E. coli and C. trachomatis were the major causative agents. Use of a set of diagnostic approaches including clinical symptoms, urine culture and more precise techniques such as PCR should be taken into consideration for the definitive diagnosis.

AbstractTo describle how respiratory tract infections (RTIs) that occurred in children with allergic asthma (AA) on allergen immunotherapy (AIT) during an influenza season. Data including clinical symptoms and treatment history of children (those with AA on AIT and their siblings under 14 years old), who suffered from RTIs during an influenza season (Dec 1st, 2019–Dec 31st, 2019), were collected (by face to face interview and medical records) and analyzed. Children on AIT were divided into 2 groups: stage 1 (dose increasing stage) and stage 2 (dose maintenance stage). Their siblings were enrolled as control. During the study period, 49 children with AA on AIT (33 patients in stage 1 and 16 patients in stage 2) as well as 49 children without AA ( their siblings ) were included. There were no significant differences in occurrences of RTIs among the three groups (p > 0.05). Compared with children in the other two groups, patients with RTIs in stage 2 had less duration of coughing and needed less medicine. Children on AIT with maintenance doses had fewer symptoms and recovered quickly when they were attacked by RTIs, which suggested that AIT with dose maintenance may enhance disease resistance of the body.

Abstract Background Hydronephrosis (HN) is the most common abnormality detected on prenatal ultrasound. This study sought to stratify outcomes of patients by severity of prenatal HN with postnatal outcomes. Methods This was a retrospective review of patients referred to a tertiary care fetal-maternal clinic with diagnosis of prenatal HN from 2004 to 2019. HN severity was categorized as mild, moderate, or severe. Data were analyzed to determine the association between HN severity and surgical intervention. Decision for surgery was based on factors including history of multiple urinary tract infections, evidence of renal scarring, and/or reduced renal function. Surgery-free survival time was represented by the Kaplan–Meier method, and hazard ratios were calculated using the log-rank test. Results 131 kidneys among 101 infants were prenatally diagnosed with hydronephrosis; 35.9% had mild HN, 29.0% had moderate HN, and 35.1% had severe HN. 8.5% of patients with mild HN, 26.3% of patients with moderate HN, and 65.2% of patients with severe HN required surgery. Patients with severe HN were 12.2 (95% CI 6.1–24.4; p < 0.001) times more likely to undergo surgery for HN than patients with mild HN and 2.9 (95% CI 1.5–5.3; p = 0.003) times more likely to undergo surgery than patients with moderate HN. Patients with moderate HN were 4.3 times more likely to require surgery than patients with mild HN (95% CI 1.5–12.9; p = 0.01). Median age at surgery was 11.8 months among patients with mild HN (IQR 11.7–14.1 months), 6.6 months among patients with moderate HN (IQR 4.2–16.4 months), and 5.4 months among patients with severe HN (3.7–12.4 months). Conclusion Among this cohort of referrals from a fetal-maternal clinic, severity of HN correlated with increased likelihood of surgical intervention. Continued assessment of patients with prenatal HN should be evaluated to best determine the role of the pediatric urologist in cases of prenatal HN.

Since 2015, annual West Nile virus (WNV) outbreaks of varying intensities have been reported in France. Recent intensification of enzootic WNV circulation was observed in the South of France with most horse cases detected in 2015 (n = 49), 2018 (n = 13), and 2019 (n = 13). A WNV lineage 1 strain was isolated from a horse suffering from West Nile neuro-invasive disease (WNND) during the 2015 episode in the Camargue area. A breaking point in WNV epidemiology was achieved in 2018, when WNV lineage 2 emerged in Southeastern areas. This virus most probably originated from WNV spread from Northern Italy and caused WNND in humans and the death of diurnal raptors. WNV lineage 2 emergence was associated with the most important human WNV epidemics identified so far in France (n = 26, including seven WNND cases and two infections in blood and organ donors). Two other major findings were the detection of WNV in areas with no or limited history of WNV circulation (Alpes-Maritimes in 2018, Corsica in 2018–2019, and Var in 2019) and distinct spatial distribution of human and horse WNV cases. These new data reinforce the necessity to enhance French WNV surveillance to better anticipate future WNV epidemics and epizootics and to improve the safety of blood and organ donations.

Abstract Background Community-acquired extended-spectrum β-lactamase (ESBL) producing Enterobacteriaceae infections pose unique treatment challenges. Identifying risk factors associated with ESBL Enterobacteriaceae infections outside of prior colonization is important for empiric management in an era of antimicrobial stewardship. Methods We randomly selected 251 adult inpatients admitted to an Intermountain healthcare facility in Utah with an ESBL Enterobacteriaceae urinary tract infection (UTI) between January 1, 2001 and January 1, 2016. 1:1 matched controls had UTI at admission with Enterobacteriaceae but did not produce ESBL. UTI at admission was defined as urine culture positive for &gt; 100,000 colony forming units per milliliter (cfu/mL) of Enterobacteriaceae and positive symptoms within 7 days prior or 2 days after admission. Repeated UTI was defined as more than 3 episodes of UTI within 12 months preceding index hospitalization. Cases with prior history of ESBL Enterobacteriaceae UTIs or another hospitalization three months preceding the index admission were excluded. Univariate and multiple logistic regression techniques were used to identify the risk factors associated with first episode of ESBL Enterobacteriaceae UTI at the time of hospitalization. Results In univariate analysis, history of repeated UTIs, neurogenic bladder, presence of a urinary catheter at time of admission, and prior exposure to outpatient antibiotics within past one month were found to be significantly associated with ESBL Enterobacteriaceae UTIs. When controlling for age differences, severity of illness and co-morbid conditions, history of repeated UTIs (adjusted odds ratio (AOR) 6.76, 95% confidence interval (CI) 3.60–13.41), presence of a urinary catheter at admission (AOR 2.75, 95% CI 1.25 – 6.24) and prior antibiotic exposure (AOR: 8.50, 95% CI: 3.09 – 30.13) remained significantly associated with development of new ESBL Enterobacteriaceae UTIs. Conclusion Patients in the community with urinary catheters, history of recurrent UTIs, or recent antimicrobial use can develop de novo ESBL Enterobacteriaceae UTIs.

Xanthogranulomatous pyelonephritis is a rare form of chronic pyelonephritis that generally afflicts middle-aged women with a history of recurrent urinary tract infections. Its pathogenesis generally involves calculus obstructive uropathy and its histopathology is characterized by replacement of the renal parenchyma with lipid filled macrophages. This often manifests as an enlarged, nonfunctioning kidney that may be complicated by abscess or fistula. This case details the first reported case of xanthogranulomatous pyelonephritis complicated by urinothorax, which resolved on follow-up chest X-ray after robot-assisted nephrectomy.
