Tips and Tricks

What organisms do Cephalosporins not cover? Remember LAME: Listeria, Atypicals, MRSA, and Enterococci

Picture this: you’re seeing a 3 year old girl with fever for 4 days, cough and runny nose (her parents estimate that since starting preschool she has had cough and runny nose 75% of the time). She has no evidence of otitis media, or strep throat; her lung exam is difficult because she is uncooperative, but she is not tachypneic, has no increased work of breathing, and her O2 sat is 97% on room air. A clean-catch urine shows 1+ leukocytes with 6-10 wbc/hpf on micro; urine culture has been sent. A chest x-ray shows some vague haziness along the right heart border; radiologist read will not be available until tomorrow. Both diagnoses of UTI and pneumonia are possible but not clear-cut. What antibiotic covers both situations? While high-dose amoxicillin and augmentin are first-line for community-acquired pneumonia (CAP) in < 5-year-olds, resistance by UTI bugs to these antibiotics is high. While cephalexin is often used to treat pediatric UTI, first-generation cephalosporins are not a good choice for CAP. Your best bet is a 2nd or 3rd generation cephalosporin such as cefixime, cefdinir, or cefibuten. (Cefuroxime is not available in suspension form in the USA).

The use and interpretation of rapid COVID-19 tests to reduce transmission is changing slightly with new variants and increased natural and vaccine-induced immunity in the population. A positive rapid test (even a very faint line) remains a good indicator of infectivity. However, some COVID-19 symptoms are now seen early in the disease course before the rapid test is positive. These are symptoms produced by the body’s immune response (something we now have due to natural or vaccine-induced immunity) to the virus – symptoms such as nasal congestion and runny nose, fever, sore throat. Symptoms produced by the virus damaging body cells (loss of taste or smell, diarrhea, shortness of breath) come later. Thus, if someone begins having scratchy throat and runny nose, rapid tests negative, and assumes they “just have a cold,” they may unwittingly build to a higher viral load in the next few days (that would turn a rapid test positive) and infect others with COVID-19. This is the reasoning behind recommendations for repeat testing 48 hours after an initial negative in symptomatic patients and for doing throat + nasal swabs to increase test sensitivity.

We are seeing unprecedented numbers of cases of RSV, and many of our patients are older school-age children. Ever wonder when those kids can return to school? RSV is contagious up to 8 days after symptom onset, so children can return to school on the 9th day after symptoms started. However, young infants and immunosuppressed children may shed active virus for up to 4 weeks.

While up to 10% of patients may think they have an allergy to beta-lactam antibiotics, fewer than 1% have a true IgE-mediated hypersensitivity, with concomitant risk of anaphylaxis. However, even if a true allergy is confirmed, this does not mean that the patient cannot receive any beta-lactam antibiotics. Whether or not there is likely to be cross-reactivity between the antibiotic to which the patient is allergic and another beta-lactam antibiotic depends on whether their structures share similar R side chains, as explained in this article. A handy can be kept on your mobile phone delineating which antibiotics cross react.

Parent / guardian unsure of the child's immunization history? Almost every state has an immunization registry, and EMRs are often configured to be able to access them - ask your institution's IT person how if that's possible. For a quick powerpoint on the immunizations that matter for ED care, check this out.

You've probably heard... AAP Subcommittee on Febrile Infants came out with new guidelines. The algorithms have been posted on PEMsource algorithms page, and the fever table updated to reflect them.

Also, the CDC came out with new guidelines regarding STI treatment. The summary wall poster can be found on the PEMsource On Shift tab. Some highlights: higher dose of ceftriaxone recommended for uncomplicated gonococcal infections, doxycycline only is 1st line for chlamydial infection (azithromycin no longer 1st line), and sex-specific dosing for trichomoniasis treatment. Also recommended IV regimen to treat PID is ceftriaxone + doxycycline + metronidazole; clindamycin & gentamicin now an alternate regimen.

Treating abscesses by making two smaller incisions and placing a loop through them is becoming popular, preferred by many over traditional I&D. For a review of the technique: https://pemcincinnati.com/blog/loop-abscess/ Don’t have a vessel loop? You can use the cuff of any glove – doesn’t need to be sterile as abscesses themselves aren’t! 

Of course, we're going to test everyone for COVID, but this handy chart from National Jewish helps differentiate the common symptoms and course of COVID-19 with those of colds, influenza, and allergies

A trio of recent publications on pediatric UTI offer some insights. First, Mattoo et al offer a review of UTI diagnosis and management in children. Nadeem et al studied the optimal WBC cutoffs for diagnosing UTI, balancing overdiagnosis/overtreatment with underdiagnosis/missed UTIs, based on the specific gravity and found them to be: 3 WBC/hpf for spec grav < 1.011, 6 WBC/hpf for 1.011-1.020, and 8 WBC/hpf for spec grav > 1.020. And Liang et al reviewed 2144 PED visits in < 2yo and calculated likelihood ratios and posttest probabilities for various urinalysis findings. UTI prevalence was 9.2%, which the authors used as the pretest probability. Likelihood ratios for leukocytes were: 1+ 2.79. 2+ 7.53, 3+ 37.68. Nitrite positivity carried a LR of 25.35. WBC/hpf at 5-10 had a LR of 1.2 (95CI 0.7-2.04), 10-20 LR 1.82, 20-50 LR 11.18. Few bacteria had an LR of 1.46, moderate 6.05, many 14.04. 

To remember the difference in antibiotic regimens for chlamydia cervicitis / urethritis vs pelvic inflammatory disease, rap this in your head: Ceph 10 x 50 for GC is nifty; give Zith 1 gram for the chlam, but doxy 14 days BID is needed for PID
Here's a great way to store your N-95 for re-use
Respiratory virus season is here, and we all know that the FDA recommends against the use of OTC cough medications in children < 4 years old (due to too many adverse effects and lack of efficacy). Some studies have shown honey to be something useful we can recommend to frustrated parents, but how exactly is it administered? Studies tested from 2.5mL to 10gm (5mL of honey = ~ 7gm). Pulling the results together, 5mL of honey can be mixed in any non-caffeinated drink, such as warm lemon water, herbal tea, or warm skim milk, and given at bedtime or up to TID. Giving it longer than 3 days had no added benefit. There is some evidence that dark honey is more effective. (Oduwole et al Cochrane Database Syst Rev 2018 Apr 10;4:CD007094).
Staying with the topic of urine... investigators at University of Pittsburgh have derived and validated a UTI risk calculator for patients aged 2-23 months. The calculator (UTICalc) is linked from the On Shift page of PEMsource under the heading Neonatal / Infant, and can be found at https://uticalc.pitt.edu/ The study by Shaikh et al was published online on April 16, 2018 at JAMA pediatrics here. Some highlights: derived on consecutive 2-23mo old febrile patients evaluated in ED for UTI, 542 with UTI and 1144 matched controls without UTI. Validated on a dataset of 380 patients, 30 with UTI. Investigators estimate sensitivity of UTICalc at 95-100% and state that use of the calculator results in approximately 10 patients tested for every 1 UTI found; UTICalc outperformed the current AAP algorithm in both of these outcomes. Users can also enter urinalysis dip, micro, and gram stain results to obtain post-test probabilities. Investigators suggest testing when pre-test probability is 2% or higher, and treating when post-test probability is 5% or higher. Further validation is warranted, but UTICalc may be useful in shared decision making with parents to give a ballpark risk estimate.
Placing topical anesthetic (EMLA, LMX4) on skin abscesses may result in spontaneous drainage, precluding need for incision. If topical anesthetic doesn't result in spontaneous drainage, it at least provides some skin anesthesia prior to local anesthetic injection for incision and drainage procedure. In one published retrospective study, 26 of 110 patients with the topical anesthetic LMX4 placed had spontaneous drainage, 3 of whom required no further intervention: https://www.ncbi.nlm.nih.gov/pubmed/21129885
Use a glass test tube or specimen tube to press on a rash to see if it blanches - remember, petechiae and purpura don't blanch. You can also use a glass test tube as a mini-anoscope to blanch surrounding mucosa and assist in identifying anal fissures in infants.

Parents bring in their 11 month old baby for a new-onset rash. The baby is unimmunized by parent choice. The baby had fever for the last 3 days to a maximum of 104 F. Although he had fever, he was well-appearing and still eating normally and playful. But since the fever was persistent, they took him to a clinic yesterday and he was diagnosed with a throat infection and started on amoxicillin. He has received 2 doses. Today he awoke with a fine morbilliform blanching pink rash that started on the neck and trunk, then has spread to the face and extremities. It does not seem itchy and it does not involve the mucosa. The only other medication he has had was acetaminophen yesterday at 5pm. On exam, he is nontoxic and interactive. Vital signs: temp 98.9 F, HR 132, RR 28, O2 sat 99% on room air. ENT, chest, and abdomen exams are unremarkable.

You are seeing a 3 year old boy with unresolving right-sided ear infection. He was first seen 1 month ago and diagnosed with right AOM and prescribed 10 days of amoxicillin. He returned after completing that course with ongoing pain, was diagnosed with persistent right AOM, and prescribed 10 days of augmentin. He has completed the augmentin and was feeling a little bit better for a few days before his symptoms returned and then became worse. He now also has a fever to 101. During the few days he felt better, he did go to a waterpark. On exam, his external auditory canal is swollen and red. Partial view of his tympanic membrane reveals it to be bright red and bulging. He indicates his entire ear when asked where it hurts, and he has swelling and redness and tenderness to palpation behind his ear as well.

The AAP Otitis Media (OM) guidelines note that the majority of OM spontaneously resolves, with a number needed to treat (NNT) with antibiotics of 15-20 in low risk cases. Clinicians and parents can elect an "observation option" in select patients that are nontoxic, have temperature < 39 C, have had ear pain for < 48 hours, and have mild ear pain, and have no otorrhea; this applies to children aged 6-23 months with unilateral OM, and children > 24 months with bilateral OM. If symptoms persist for 48-72 hours, then antibiotics should be started.

The new AAP Subcommittee on the Febrile Infant guidelines for managing febrile 8-60 day olds gives the option to perform an LP for febrile 22-28 day olds only if inflammatory markers, if obtained, are abnormal (Temp > 38.5, Procalcitonin > 0.5 ng/mL, CRP > 20 mg/dL, ANC > 4500-5200). This is an option even for the infant with a + UA. If an LP is not performed, they do recommend admission to the hospital and treatment with parenteral antibiotics. This is a change from prior practice, where concerns about masking meningitis obviated administration of parenteral antibiotics without performing the LP. What are your thoughts?
