Growth and Iron Sequestering of Pin Oak (Quercus palustris) Seedlings Inoculated with Soil Containing Ectomycorrhizal Fungi
Authors: Hauer Richard J. , Dawson Jeffrey O. 
Published: April 2022

AbstractEctomycorrhiza formation, biomass production, and iron accumulation were determined for pin oak (Quercus palustris) seedlings grown for 2 years in acidic (5.5 pH) or alkaline (7.5 pH) media and inoculated with soil from 1 of 3 sites: 1) a native pin oak forest, 2) an urban site with chlorotic pin oak trees, or 3) an urban site with non-chlorotic pin oak trees. Ectomycorrhiza formation on pin oak roots was similar for soil inocula from all 3 sites, similar for both pH treatments, and lacking on non-ectomycorrhizal seedlings that had been inoculated with autoclaved soil. Seedling biomass was greater in the acidic medium than the alkaline medium. Inoculated seedlings in the alkaline treatment had greater biomass than uninfected control seedlings inoculated with autoclaved soil in the alkaline treatment. The mean iron concentration of seedlings grown in the acidic medium (54.3 ppm) was significantly greater than that of seedlings grown in the alkaline medium (48.7 ppm). Inoculated seedlings had similar mean leaf iron concentrations despite pH differences (49.3 ppm under acidic conditions and 52.7 ppm under alkaline conditions). Mean leaf iron concentration was lowest for the uninoculated seedlings in alkaline medium (44.8 ppm), suggesting that ectomycorrhizae contribute to iron accumulation in pin oak under alkaline soil conditions. Results indicate that ectomycorrhizae influence both growth and iron sequestering under iron-limiting conditions and that some urban soils harbor infective pin oak ectomycorrhizal fungi.
Estimating Economic Activity and Impacts of Urban Forestry in California with Multiple Data Sources from the Early 1990s
Authors: Templeton Scott R. , Goldman George 
Published: April 2022

AbstractUrban forests provide tree products and aesthetic, recreational, health, and environmental benefits. Yet the expenditures that people make to secure these benefits are difficult to estimate for lack of comprehensive published data. Based on various sources of data, we estimate that Californians spent at least $947 million to obtain these benefits and the state’s urban forestry “sector” had sales of at least $1,115 billion in a 12-month period in the early 1990s. As a result of direct, indirect, and induced effects, urban forestry accounted for at least $3,384 billion in total sales. This level of sales became about $1,869 billion in annual income to individuals and supported about 57,200 jobs in this period within the state. Knowledge of this economic activity is important, in principle, to voters and public decision-makers who allocate human resources, tax revenue, and water for the management of community forests and other natural resources in California.

Arthroplasty after septic arthritis of the native hip and knee: retrospective analysis of 49 joints
Authors: Portier Elodie , Zeller Valérie , Kerroumi Younes , Heym Beate , Marmor Simon , Chazerain Pascal 
Published: April 2022

Abstract. Background: Arthroplasty after septic arthritis (SA) treatment raises
diagnostic and therapeutic questions. The main objective was to evaluate
infection-free survival of patients undergoing total knee arthroplasty (TKA) or total hip
arthroplasty (THA) post-SA. Other objectives were to describe the
population's characteristics, surgical strategies, results of preoperative
examinations and cultures of intraoperative samples taken at implantation,
and postoperative antibiotic therapy.
Methods: This is a retrospective, observational, monocenter study, from January 2005 to May 2019, including all patients undergoing TKA or THA with prior or ongoing SA
in the same joint. Infection–free survival was analyzed and reported.
Results: Forty-seven patients, 29 men, 49 joints operated on (30 knees, 19 hips),
were included. Median SA-to-arthroplasty interval was 32 [1–216] weeks. It
was <2 years for 43 joints and <6 months for 19 joints. Six
patients underwent arthroplasty while still on SA treatment. One-stage
arthroplasty was done for 43 joints and two-stage arthroplasty for 6 joints. Eight (16 %)
cultures of intraoperative specimens were positive. Median durations of
postoperative antibiotic therapy were 10 d for sterile cultures and 82 d for those that were positive. At 2 years, infection-free survival rate was
95.9 % (±0.02). After a median follow-up of 47 [18–142] months, no SA
relapse was observed, but five patients developed new periprosthetic joint infections (PJIs) with a different
microorganism.
Conclusion: Arthroplasty may be a post-SA option, even within a short period of time.
One-stage arthroplasty can be done if synovectomy is thorough,
intraoperative samples are taken and antibiotics are administered until those
culture results become available. We observed no SA relapse, but new PJIs
occurred.

Results of penicillin skin testing in patients with suspected penicillin allergy – the Qatar experience
Authors: Mudawi Dalal , Taha Salma , Ibrahim Yaldez , Omar Mervat , Mobayed Hassan 
Published: April 2022

Background: Unverified penicillin allergy has been linked to adverse patient events and increased healthcare expenditure owing to the usage of broad-spectrum, expensive antibiotics. Penicillin allergy test is the gold standard to diagnose penicillin allergy; and in this study, we present data from Qatar which have not been published before.
Methods: Patients with a history of penicillin allergy who underwent penicillin allergy testing between January 2015 and December 2020 at the Allergy Division of the Hamad General Hospital were retrospectively reviewed from the division registry. Benzylpenicilloyl-polylysine (PPL) and minor determinant mixture (MDM) kit DAP-penicillin (0.04 mg +0.5 mg)/vial) (penicillin G, amoxicillin (20 mg/vial), and lately clavulanic acid (20 mg/vial) (DAP, Diater, Madrid, Spain) were used for skin and intradermal testing according to published guidelines. Patients with negative skin tests were administered direct oral challenge with amoxicillin/clavulanate (500/125 mg) and observed for 2 hours.
Results: Of the 189 charts reviewed, 183 patients had a complete data set for analysis. Patients were predominantly women (n = 132, 72%) with an average age of 42 years. Of these patients, 149 (81.4%) had a history of an immediate allergic reaction to penicillin, 10 had a history of delayed reactions, and 24 had other or undefined reactions. A total of 39 (21.3%) patients were diagnosed with penicillin allergy (30 patients with positive skin test results and 9 using a direct oral challenge).
Of the 30 patients with positive skin testing, 5 reacted to PPL, 8 to MDM, 13 to amoxicillin, and 4 to clavulanic acid.
Conclusion: Previous studies indicate that 90% patients with a history of penicillin allergy were able to tolerate the drug (10% were truly allergic). Our data showed that 21% were truly allergic to penicillin. This high positive rate can be attributed to the high pretest probability based on the detailed history obtained before the test, which led to the exclusion of patients with symptoms incompatible with penicillin allergy from the test.
Correlation between skin test results and historical manifestations in patients with suspected lidocaine hypersensitivity
Authors: Khalil Sally , Taha Salma , Al-Nesf Maryam 
Published: April 2022

Background: Adverse reactions to local anesthetics (LA) are relatively common; however, true IgE-mediated allergy is extremely rare, estimated to occur in less than 1%. Investigating patients with suspected allergy to LA should begin with a detailed history to exclude other more common operation theater related culprit medications, followed by skin testing. The subcutaneous challenge is considered the gold standard for confirming true IgE-mediated allergy to LA. In this study, we have described the skin prick test results of patients with suspected lidocaine allergy who had historical reaction symptoms typical to IgE-mediated allergic reactions.
Methods: The data were retrieved from the allergy procedure log registry for patients who were referred to the allergy clinic with a suspected allergic reaction to lidocaine at the Hamad Medical Corporation between 2016 and 2020. These patients’ symptoms of historical reactions to lidocaine were compared to their skin test results.
Result: A total of 7 patients were identified. The skin test result for lidocaine was positive in only 1 patient; his historical reaction was anaphylaxis (urticaria/angioedema and shortness of breath). The remaining 6 patients had a negative result for skin and challenge tests. Of these 6 patients with negative results, 4 had only urticaria/angioedema as historical reactions; 1 had systematic manifestation (tachycardia) along with urticaria/angioedema, and 1 experienced systemic symptoms (shortness of breath, chest pain, and palpitation) with no skin or mucous membrane involvement ().
Conclusion: Negative skin test and subcutaneous challenge with a history of generalized cutaneous symptoms and/or systemic symptoms during the reaction to LA can be attributed to many causes, such as an IgE-mediated reaction against a component other than lidocaine (e.g., latex), medication side effects (adrenaline in combined preparations), and/or symptoms of primary disease (chronic spontaneous urticaria/angioedema).
Contact dermatitis in hemodialysis patients at Al Wakra hospital
Authors: Elmadhoun Ihab , Mahi Saad , Pulikkan Rony , Emam Ahmed 
Published: April 2022

Background: Patients undergoing hemodialysis are exposed to various potential allergens from medication, dialysis catheters, topical antiseptics, and different adhesive dressings. Many patients develop a local allergic reaction and get itchy rashes, which may get infected, leading to significant morbidity and preventable health cost. In this study, we aimed to report the incidence of contact dermatitis (CD) and its potential complications in hemodialysis (HD) patients at the Al Wakra Hospital Dialysis unit.
Methods: We performed a retrospective chart review of documented local allergic reactions at vascular access sites for the HD patients at the Al Wakra Hospital.
Results: Currently, 102 patients are getting maintenance HD through catheters or arteriovenous (AV) fistula. Twelve (14.4%) patients developed CD (7 [58%] had cuffed jugular dialysis catheter, and 5 [42%] had an AV fistula). Most patients (75%) developed CD in the early period of dialysis initiation, and 25% developed it later in the course. Most patients responded to removing adhesive plasters and dressing the vascular access site using gauze only and topical steroids (hydrocortisone 1% cream/mometasone 0.1% cream). Two (16.6%) of the 12 patients developed vascular access site infection, of whom 1 had an AV fistula and developed a severe rash with cellulitis leading to sepsis and 2 admissions, although blood cultures remained negative. The patient responded to IV antibiotics and local mometasone 0.1% cream. Complete removal of all adhesive tapes helped prevent recurrence of the rash. Later, dressing of the AV fistula site was performed only with a cotton gauze. The second patient had a jugular catheter and developed an allergic rash leading to cellulitis and tunnel infection. Swab culture showed Staphylococcus aureus from the exit site sensitive to cloxacillin/cefazolin. The patient improved after local and oral antibiotics and removal of adhesive tapes. The catheter was not removed, and the patient did well.
Conclusion: The incidence of CD at our dialysis unit is 14.4%. Previously published reports from other dialysis units showed a lower incidence of 1.25%. Early identification and diagnosis of allergic rash at the vascular access site and avoidance of adhesive plasters and other potential allergens prevent complications like infection and loss of precious vascular accesses in these patients.
Chronic urticaria and COVID-19 vaccination: Qatar data (preliminary report of COVAC-CU-international)
Authors: Purayil Saleema , Thalappil Sherin , Al-Nesf Maryam , Kocaturk Emek 
Published: April 2022

Background: It is a well-known fact that patients with chronic urticaria (CU) are not at a higher risk for a serious allergic reaction such as anaphylaxis from medications. However, there is a fear and some misconceptions regarding allergic reactions to the COVID-19 vaccine among patients and physicians, which might result in resistance to vaccination. Data about the incidence and severity of COVID-19 vaccine reactions in the CU population are scarce. In this study, we aimed to evaluate the real-world (Qatar) experience of the effects of COVID-19 vaccination on patients with CU and analyze the rates of vaccine-associated reactions and risk factors associated.
Methods: This is a cross-sectional questionnaire-based study conducted as a part of COVAC-CU international under the GALEN UCARE program. Adult patients with CU who received one or more doses of COVID-19 vaccination were administered a questionnaire regarding their demographic characteristics and any potential unfavorable effect of the vaccination from the November 03 to December 31, 2021.
Results: These are preliminary results from an ongoing study. The data were collected from 91 patients with CU, of whom 79.12% had chronic spontaneous urticaria, 15.3% had chronic inducible urticaria, and the remaining had both. Of these patients, 74.7% were women. The average age of the patients was 39.3 (range 15–68) years. The majority (84.6%) of them received 2 vaccine doses, 13.1% received 3 doses, and the remaining received 1 dose. Most (70.3%) of these patients did not experience any worsening in CU after vaccination. A total of 62.6% patients reported some type of side effects to the vaccine (16.4% had CU exacerbation and 46.1% other types of reactions, such as fever and muscle pain). None of the patients reported anaphylaxis. Two patients reported improvement in their symptoms.
Conclusion: Our local data suggest that patients with CU in Qatar can safely take the COVID-19 vaccine. Most patients with CU did not experience any worsening in symptoms, and there were no reports of a severe reaction (anaphylaxis). We recommend maximizing symptom control prior to vaccination to minimize the risk of worsening urticarial symptoms.
Labeling of penicillin allergy in patients admitted to a tertiary hospital in Qatar: A retrospective audit
Authors: Hasan Elajez Reem , Bakdach Dana , Al-Adawi Rana , Elgaily Dina , Karawia Ahmed , Mohamed Asmaa 
Published: April 2022

Background: Penicillin (PNC) allergy is a major healthcare concern that necessitates antibiotic substitution which is associated with increased costs, worse clinical outcomes, and increased risks of antimicrobial resistance. Many patients are labeled as PNC allergic; however, this has been rarely confirmed. In this audit, we aimed to determine the characteristics of PNC allergy labeling.
Methods: A list of all the patients labeled with PNC allergy who presented to the Hamad General Hospital (HGH) for any medical reason from January to December 2021 was generated from pharmacy system. Of those, 30% were randomly selected for audit review. Electronic health records of the selected patients were retrospectively reviewed to identify the allergy labeling characteristics and whether the patients had recently received an antibiotic within the PNC class without developing any allergic reaction.
Results: Of the 464 patients identified with labelled PNC allergy, 139 patients were randomly selected and reviewed. Of the reviewed patients, 82 (59%) were women with an average ( ± SD) age of 46 ( ± 16.5) years. Forty-six patients were categorized to have a mild PNC allergy, and only 18 were categorized as severe with the remaining patients categorized as having a moderate PNC allergy. Despite documentation of severity, an accurate description of the allergic reaction event was significantly lacking with only 30/139 (21.5%) patients having clear documentation of the event description. Twenty (14.4%) patients labeled as PNC allergic received at least one antibiotic within the PNC class (e.g., piperacillin-tazobactam, ampicillin-sulbactam, or amoxicillin-clavulanic acid) safely without any documented reactions. Interestingly, of those 20 patients, 4 were categorized as being severely allergic to PNC. However, as more than 80 patients presented to the hospital for reasons not requiring antibiotics; experiences with PNC could not be assessed effectively.
Conclusion: Poor documentation of the details of allergic reactions may falsely affect future antibiotic decisions. The results of this audit highlight the need for standardizing the documentation process of medication allergy. In addition, reviewing the patient's experience with other drugs within the PNC class can guide healthcare providers during the PNC allergy evaluation.
