Background: Patients with severe coronavirus disease-2019 (COVID-19) are susceptible to superimposed infections.

Objectives: To describe COVID-19 patients who presented with complications due to Candida bloodstream co-infection (candidemia) and their outcome in a single center in northern Israel (Emek Medical Center) during the second outbreak of COVID-19 in Israel (15 June 2020 to 20 September 2020).

Methods: A retrospective study of COVID-19 patients presenting with candidemia was conducted, including clinical and laboratory data. The incidence of candidemia among hospitalized COVID-19 patients was compared to a historical cohort of non-COVID-19 controls.

Results: Three COVID-19 patients complicated with candidemia were documented. All three patients died shortly after the detection of candidemia. Three different Candida sp. were isolated from the blood cultures: C. albicans, C. parapsilosis, and C. glabrata. The incidence of candidemia among COVID-19 patients was 0.679 episodes per 1000 hospital days.

Conclusions: Our small sample suggests a much higher incidence of candidemia among COVID-19 patients compared to a historical cohort of non-COVID-19 controls. All clinicians treating COVID-19 patients in GICU should be aware of this complication

Background: Urinary tract infection (UTI) is a common bacterial infection in children.

Early treatment may prevent renal damage in pyelonephritis. The choice of empiric antibiotic treatment is based on knowledge of the local susceptibility of urinary bacteria to antibiotics. In Israel the recommended empiric oral antibiotic treatment are First or second generation cephalosporin, trimethoprim-sulfamethoxazole or amoxicillin-clavulanic acid.

Objectives: To describe resistance rates of urine bacteria isolated from children with UTI in the community settings. Identify risk factors for resistance.

Methods: A retrospective cross-sectional study of UTI in children aged 3 months to 18 years diagnosed with UTI and treated as outpatients in a large community clinic between 7/2015 and 7/2017 with a diagnosis of UTI.

Results: A total of 989 urinary samples were isolated, 232 were included in the study. Resistance rates to cephalexin, cefuroxime, ampicillin/clavulanate and Trimethoprim-Sulfamethoxazole were 9.9%, 9.1%, 20.7%, and 16.5%, respectively. Urinary tract abnormalities and recurrent UTI were associated with an increase in antibiotic resistance rates. Other factors such as age, fever, and previous antibiotic treatment were not associated with resistance differences.

Conclusions: Resistance rates to common oral antibiotics were low compared to previous studies performed in Israel in hospital settings. First generation cephalosporins are the preferred empiric antibiotics for febrile UTI for outpatient children. Amoxicillin/clavulanate is not favorable due to resistance of over 20% and the broad spectrum of this antibiotic. Care should be taken in children with renal abnormalities as there is a worrying degree of resistance rates to the oral first line antibiotic therapy.

Background: The need for postnatal monitoring of infants exposed to intrauterine beta blockers (BBs) has not been clearly defined.

Objectives: To evaluate infants exposed to intrauterine BBs in order to estimate the need for postnatal monitoring.

Methods: This retrospective case-control study comprised 153 term infants born to mothers who had been treated with BBs during pregnancy. Treatment indications included hypertension 76 mothers (49.7%), cardiac arrhythmias 48 (31.4%), rheumatic heart disease 14 (9.1%), cardiomyopathy 11 (7.2%) and migraine 4 (2.6%). The controls were infants of mothers with hypertension not exposed to BBs who were born at the same gestational age and born closest (before or after) to the matched infant in the study group.

Results: Compared to the control group, the infants in the study group had a higher prevalence of early asymptomatic hypoglycemia (study 30.7% vs. control 18.3%, P = 0.016), short symptomatic bradycardia events, other cardiac manifestations (P = 0.016), and longer hospitalization (P < 0.001). No life-threatening medical conditions were documented. The birth weight was significantly lower for the high-dose subgroup compared to the low-dose subgroup (P = 0.03), and the high-dose subgroup had a higher incidence of small-for-gestational-age (P = 0.02).

Conclusions: No alarming or life-threatening medical conditions were observed among term infants born to BB treated mothers. These infants can be safely observed for 48 hours after birth close to their mothers in the maternity ward. Glucose follow-up is needed, especially in the first hours of life.

Background: The estimated incidence of esophageal atresia (EA) with or without tracheo-esophageal fistula (TEF) is 1:3500 live births. During childhood these patients have various co-morbidities, but the overall quality of life among adults is similar to that of the general population.

Objectives: To evaluate short- and long-term co-morbidities and quality of life among infants born with EA ± TEF at a large single medical center.

Methods: Medical records of 65 children born over a 21 year period were reviewed for short- and long-term medical data. Telephone interviews were conducted with 46 of their parents regarding medical problems and quality of life after home discharge.

Results: The main long-term co-morbidities during the first 2 years of life, 4–6 years of age, and during adolescence (12–16 years) included gastro-esophageal reflux disease (GERD) in 56.5%, 35.8%, and 18.7%, respectively; stridor in 84.8%, 45.2%, and 12.5%, respectively; hyper-reactive airway disease (HRAD) in 43.5%, 35.5%, and 36.5%, respectively; recurrent pneumonia in 43.5%, 32.3%, and 18.8%, respectively; and overall recurrent hospitalizations in 87%, 41.9%, and 25%, respectively. The quality of life was reportedly affected among 100%, 75%, and 33.3% respectively.

Conclusions: Long-term follow-up of patients with EA ± TEF indicates a high burden of co-morbidities during the first 6 years of life, with a gradual decrease in symptoms thereafter. Nevertheless, HRAD continued to impact the daily life of about one-third of the older adolescents, and GERD one-fifth. A long-term multidisciplinary follow-up should be conducted to prevent late onset complications that may affect the quality of life.

Background: Ureaplasma species (Usp) are the most prevalent genital Mycoplasma isolated from the urogenital tract of both men and women. Usp may be commensals in the genital tract but may also be contributors to a number of pathological conditions of the genital tract. Because they can also just colonize the genital tract of healthy people, their pathogenic role can be difficult to prove.

Objectives: The aim of the study was to evaluate the efficacy of a quantitative polymerase chain reaction (qPCR) method for the discrimination between infection and colonization by measuring prevalence of Usp in asymptomatic versus symptomatic patients.

Methods: Urine samples were tested for U. parvum and U. urealyticum using a semi-quantitative multiplex PCR technique for sexually transmitted diseases (Anyplex™ STI-7 Detection Kit, Seegene, South Korea). A total of 250 symptomatic and 250 asymptomatic controls were included.

Results: A strong positive result for U. parvum was significantly more prevalent in symptomatic compared to asymptomatic patients. This finding was observed especially in women and in the young group (15–35 years of age). No significant differences were observed between the prevalence in symptomatic and asymptomatic patients of U. parvum with low strength of positivity and for U. urealyticum in all groups by age, gender, and strength of positivity.

Conclusions: The significant difference between the symptomatic and asymptomatic group in the highest positivity group for U. parvum using the Anyplex™ STI-7 detection kit in urine may indicate a high probability of infection rather than colonization, especially in women and young patients.

Background: Recent studies show that vaccination of health care workers (HCW) might reduce influenza transmission and mortality among hospitalized patients. No studies have compared the incidence of laboratory-proven influenza in vaccinated versus unvaccinated hospital HCW. 

Objectives: To evaluate the effectiveness of influenza vaccination among hospital HCW and to examine the attitudes of this population towards influenza vaccination.

Methods: We performed a prospective cohort study between 1 January and 30 April 2014 of 1641 HCW at our medical center; 733 were vaccinated and 908 not vaccinated. A random sample of 199 subjects was obtained: 97 vaccinated and 102 non-vaccinated. Participating individuals were contacted on a weekly basis during the flu season and were asked to report any respiratory or flu symptoms and, if positive, to undergo a polymerase chain reaction (PCR) test for influenza. 

Results: In the general HCW population, vaccination was more frequent among physicians 298/498 (58%) than among nurses (324/862 (38%) and among males than females. Flu symptoms were reported by 20 of 199 participants, 13 in the non-vaccinated group (12.7%) and 7 in the vaccinated group (7.2%). A positive PCR test for influenza A virus was present in 4 of 20 people tested (20%). All positive cases were from the non-vaccinated group (P = 0.0953). 

Conclusions: Non-vaccinated HCW showed a higher, although not statistically significant, tendency for contracting laboratory-proven influenza than the vaccinated population. The main reasons for vaccination and non-vaccination were personal beliefs and habits. Education efforts are needed to improve compliance. Larger studies could further clarify this issue.

 Background: Radiation treatment of spinal and paraspinal tumors has been limited by the tolerance of the spinal cord. As such, therapeutic options are restricted to surgically accessible lesions or the use of suboptimal dosing of external beam irradiation.

Objectives: To evaluate the safety and applicability of the Elekta Synergy-S radiation unit for the treatment of spinal tumors.

Methods: We retrospectively reviewed all patients treated with stereotactic radiosurgery to spinal tumors between November 2007 and June 2011.

Results: Thirty-four patients were treated for 41 lesions. Treatment indications were local tumor control and pain palliation. The mean follow-up was 10.8 ± 11.6 months (range 0.5–38 months). No acute radiation toxicity or new neurological deficits occurred during the follow-up period. Local tumor control was achieved in 21 of the 24 lesions (87.5%) available for radiological follow-up at a median of 9.8 months (range 3–32 months). Good analgesia was achieved in 24/30 lesions (80%) that presented with intractable pain.

Conclusions: The safety and feasibility of delivering single and multiple-fraction stereotactic spinal irradiation was demonstrated and became a standard treatment option in our institution.

 Background: Contrast-induced nephropathy (CIN) is one of the major causes of new-onset renal failure in hospitalized patients. Although renin-angiotensin-aldosterone system (RAAS) blocking agents are widely used among patients requiring contrast studies, data on the effect of these agents on the development of CIN are sparse and inconsistent.  

Objectives: To evaluate in a randomized control trial whether uninterrupted administration of angiotensin II (AngII) blockade medications influence estimated glomerular filtration rate (eGFR) in patients undergoing non-emergent coronary angiography.

Methods: Patients receiving treatment with angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (ACE-I/ARB) were recruited consecutively. The enrolled subjects were randomized into three groups at a 1:1:1 ratio: group A (ACE/ARB stopped 24 hours prior to the procedure and restarted immediately after the procedure), group B (ACE/ARB stopped 24 hours prior to the procedure and restarted 24 hours after the procedure), and group C (ACE/ARB continued throughout the study period). Plasma creatinine was measured and eGFR was calculated according to the Cockroft-Gault equation before and 48 hours after the coronary angiography. The primary endpoint was a change in eGFR at 48 hours.

Results: Groups A, B and C comprised 30, 31 and 33 patients respectively. The mean age of the study population was 65 ± 12 years and 67% were males. Fifty percent of the subjects had diabetes mellitus. The primary endpoint analysis showed that at 48 hours after the procedure there was no difference in ΔeGFR between groups A and C (4.25 ± 12.19 vs. 4.65 ± 11.76, P = 0.90) and groups B and C (3.72 ± 17.42 vs. 4.65 ± 11.76, P = 0.82). In post-hoc analysis the patients were clustered according to the following groups: medical alternation (group A and B) versus control (group C) and to baseline eGFR ≥ 60 ml/min vs. eGFR < 60 ml/min. In patients with baseline eGFR < 60 ml/min the ΔeGFR (baseline eGFR-eGFR 48 hours post-angiography) was significantly different between the intervention vs. control group (median 5.61 vs. median -2.19, P = 0.03 respectively). While in patients with baseline eGFR ≥ 60 ml/min there was no significant difference in ΔeGFR between the intervention and control groups.

Conclusions: ACE-I and ARB can safely be used before and after coronary angiography in patients with eGFR ≥ 60 ml/min.

Background: Spinal epidural abscess (SEA) is a rare disease with a potentially devastating outcome, and a reported incidence traditionally estimated at 0.2–2 cases/10,000 hospital admissions. Since the implementation in October 2007 of a program to increase medical personnel’s awareness of SEA, we have documented a sharp increase in the incidence of SEA at our medical center

Objectives: To investigate the cause of the increased incidence of SEA.

Methods: All cases diagnosed with SEA during the period 1998–2010 were retrospectively reviewed. Cases diagnosed before 2007 were compared with those diagnosed thereafter.

Results: From January 1998 to October 2007 SEA was diagnosed in 22 patients (group A), giving an annual incidence of 0.14–0.6 cases per 10,000 admissions. During the period November 2007 to April 2010, 26 additional patients were diagnosed (group B), yielding an incidence of 0.81–1.7 cases per 10,000 admissions (P < 0.01). The two groups did not differ significantly in epidemiological, clinical or laboratory characteristics, or in the causative bacteria isolated.

Conclusions: The threefold rise in the incidence of SEA observed at a tertiary medical center in Tel Aviv since November 2007 was not explained by different host characteristics or by more virulent bacterial isolates. We suggest that heightened awareness of the clinical presentation and timely utilization of MR imaging has resulted in more cases being identified.
