This paper describes a case of lung injury attributed to the use of Nitrofurantoin and a review of the relevant literature. An 88-year-old woman was admitted to the floor for the evaluation of recent symptoms of dyspnea, fatigue and productive cough. She was initiated on nitrofurantoin 300 mg per day for the treatment of a urinary tract infection 3 days earlier. Upon examination, chest auscultation revealed bilateral inspiratory crackles. Chest radiograph showed bilateral airspace and interstitial infiltrates. Laboratory studies revealed an elevated white blood cell count of 13,500/μL (reference range = 5200-12,400/μL) and blood eosinophilia (10%, reference range: 0-7%). Using clinical judgment and the algorithm of Naranjo, it was determined that nitrofurantoin use was the probable cause of the patient's lung injury. Symptomatic improvement was observed shortly after the drug was discontinued. A review of information from several European and North American pharmacovigilance databases (through June 2014) identified several reports of suspected nitrofurantoin-induced toxicity, including reports of acute toxicity reactions, which were related in many ways to the case we are reporting here.
Objective The purpose of this study is to evaluate antibiotic-prescribing practices and adherence to IDSA guidelines for the treatment of uncomplicated urinary tract infections in Lebanon. Methods This observational prospective study was conducted in 15 community pharmacies in Lebanon over 1 year in adult females. A regimen of nitrofurantoin 100 mg bid for 5 days or fosfomycin 3 grams single dose were considered appropriate. For the bivariate analysis, the chi-square test was used. Results A total of 376 patients were included in this study. The prescribed antibiotic was appropriate in 35 percent of the patients. Age (more than 50 years) did not significantly affect the appropriateness of the prescribed antibiotic (p=0.508). The frequency of attacks per year (more than 3) negatively affected the choice of antibiotic (p=0.025). The dose and duration of the prescribed antibiotic was appropriate in 73 and 58 percent of the patients, respectively, with a significant inappropriate dose and duration with fluoroquinolones as compared to nitrofurantoin and fosfomycin (p < 0.001 for the dose and p=0.014 for the duration of therapy). Conclusions In an era of increasing bacterial resistance, interventions that improve physicians' prescribing practices for uncomplicated urinary tract infections are needed.
BackgroundThe aim of the study was to evaluate the simplicity, safety, patients’ preference, and convenience of the administration of insulin using the pen device versus the conventional vial/syringe in patients with diabetes.MethodsThis observational study was conducted in multiple community pharmacies in Lebanon. The investigators interviewed patients with diabetes using an insulin pen or conventional vial/syringe. A total of 74 questionnaires were filled over a period of 6 months. Answers were entered into the Statistical Package for Social Sciences (SPSS) software and Excel spreadsheet. t-test, logistic regression analysis, and correlation analysis were used in order to analyze the results.ResultsA higher percentage of patients from the insulin pen users group (95.2%) found the method easy to use as compared to only 46.7% of the insulin conventional users group (P 0.001, relative risk [RR]: 2.041, 95% confidence interval [CI]: 1.178–3.535). Moreover, 61.9% and 26.7% of pen users and conventional users, respectively, could read the scale easily (P 0.037, RR 2.321, 95% CI: 0.940–5.731), while 85.7% of pen users found it more convenient shifting to pen and 86.7% of the conventional users would want to shift to pen if it had the same cost. Pain perception was statistically different between the groups. A much higher percentage (76.2%) of pen users showed no pain during injection compared to only 26.7% of conventional users (P 0.003, RR 2.857, 95% CI: 1.194–6.838).ConclusionThe insulin pen was significantly much easier to use and less painful than the conventional vial/syringe. Proper education on the methods of administration/storage and disposal of needles/syringes is needed in both groups.
Simple and cost-effective methods are needed to extract DNA in order to use it in large-scale studies. Blood is an excellent DNA source; however, it is costly and invasive thus an alternative is needed. Several kits and chemical protocols using buccal cells have been proposed for DNA extraction. The objective of the study is to evaluate buccal NaOH chemical protocol and Nucleospin Tissue Kit (BD Biosciences, Macery-Nagel, Germany) for DNA extraction. DNA swab samples were collected from 300 voluntary participants. DNA yields and purity were measured by NaOH and Nucleospin Tissue Kit techniques; the cost and time consumption for DNA extraction per sample were assessed as well. Results have shown that DNA amount and purity extracted by NaOH procedure was compared to that of the kit (p = 0.164; p = 0.249, respectively). NaOH method was considered cheaper and less time consuming (0.06 versus 3.80 USD, and 1.33 versus 3.59 minutes per sample, p < 0.001). Buccal cell derived DNA extracted by NaOH protocol can be considered a feasible substitute for more expensive and time-consuming kits.
A 68-year-old man diagnosed with a diabetic foot infection caused by R. ornithinolytica was successfully treated with amoxicillin-clavulanate and ciprofloxacin.
