Continuing with the electrolyte derangements in children: Hyponatremia
Hyponatremia is defined as a Sodium of less than 135 mmol/L and does not depend on patient age.
This is the most common electrolyte abnormality in pediatric patients. Excessive free water is often the culprit and is usually thought of in the neonate or infant whose guardians are mixing formula incorrectly. * Additional causes include inappropriate ADH (Antidiuretic hormone) secretion, or in the case of dehydrated patients appropriate ADH secretion. Sodium wasting is rare.
Total body water (TBW) is important to consider, and preterm neonates have higher TBW (80%) than full term (70%) and 1 year old infants (~60%) putting them at higher risk of hyponatremia.
Recognizing the volume status of the patient aids in determining the etiology of the hyponatremia and allows for appropriate treatment. This may require obtaining urine sodium.
Treatment:
Hypertonic saline should be used only for patients with severe neurologic complications including seizures or altered mentation. In these patients, a hypertonic saline bolus should be given at 3-5 ml/kg of 3% NaCl over 10-15 minutes.
In hypovolemic patients without neurologic symptoms, fluid resuscitation is the mainstay with caution to increase sodium levels by no more than 6-8mmol/L/day. For euvolemic or hypervolemic patients, fluid restriction is advised.
Prevention:
Importantly, when children receive IV fluids, the choice should be made to select isotonic fluids (0.9% NaCl) rather than hypotonic fluids (0.45% NaCl) to avoid iatrogenic development of hyponatremia.
*Reminder: 2 ounces (about 60 ml) of water should be placed in the bottle, and then 1 full scoop of formula, unless directed to have higher caloric content by their doctor- in which case the amount of formula in the mixture should be higher

Mycoplasma genitalium (M.genitalium, or Mgen) is a pathogen that is increasingly associated with cervicitis, pelvic inflammatory disease, preterm labor, spontaneous abortion, and infertility. Although many are asymptomatic, M.genitalium can be found in 10-30% of women with symptoms/exam findings of cervicitis.
NAAT testing for M.genitalium is FDA-approved for use with urine and urethral, penile meatal, endocervical, and vaginal swab samples.
According to CDC guidelines, women with recurrent or persistent cervicitis should be tested for M.genitalium, and testing should be considered among women with PID. It is not recommended to test for asymptomatic infections at this time, even in pregnancy.
High rates of macrolide resistance in this pathogen make 1 g of Azithromycin insufficient. The recommended regimen for NAAT-positive M.genitalium infections is: Doxycycline 100 mg PO BID x 7 days to reduce bacterial load, followed by moxifloxacin 400 mg PO daily x 7 days.
Overall, more studies are needed to truly determine the clinical relevance of this pathogen.
Consider testing for M.genitalium in patients presenting with recurrent or persistent cervicitis or pelvic inflammatory disease, as this may not respond to typical antibiotic regimens.

The incidence of opioid-overdose-related deaths has clearly increased in the past decade, with recent estimates of up to 17% of OHCA being opioid-related in 2023. [1,2] The use of naloxone for opiate reversal in overdose is well-established, with reasonable inference but no formal proof that its use could help in opioid-associated out of hospital cardiac arrest (OA-OHCA). [3] The August publication of two trials [4,5] retrospectively examining naloxone administration in OHCA offers some perspectives…

[View “Visual Diagnosis” for slightly more detail on the referenced studies.]
Bottom Line: While prospective trials are absolutely needed to offer more definitive evidence regarding the use of empiric naloxone in nontraumatic OHCA, the rising incidence of OA-OHCA in the U.S. and current findings are convincing enough to encourage early naloxone administration, especially in populations with higher incidence of opioid use.

In this systemic literature review of orthopedic injuries identified in intimate partner violence (IPV) the authors remind us that finger, hand, and especially isolated ulnar fractures are very commonly associated with IPV. When we see these injury patterns extra effort is required to determine if IPV is involved.

Autism Spectrum Disorder (ASD) can often be a diagnosis that complicates usual ED evaluation and management. One of the frequently asked questions is “what medications work well for patients with autism?” It is often said, although with quite variable evidence in the literature, that benzodiazepines should be avoided in patients with ASD due to the risk of paradoxical reaction.
This study was a meta-analysis that included 20 different studies that looked at efficacy and adverse effect of various medications and medication combinations for procedural sedation for a variety of painful and nonpainful procedures. Although the heterogeneity of the indications, medications, and other details of study design of the studies included precludes a definitive recommendation as to the best medication or regimen, it does suggest overall reasonable efficacy of midazolam both as a single agent as well as in combination with dexmedetomidine, especially when balanced against adverse effects noted with some of the more efficacious regimens.
Take Home Point: Medication choice for patients with ASD should be individualized to the patient based on prior experiences, parental or patient input, and prescriber experience given proven efficacy of multiple regimens. Benzodiazepines should be considered within the toolkit.

This retrospective study of Swiss trauma patients looked at blood gas oxygen levels within 3 hours of arrival to the trauma bay in severely injured patients over age 16. When comparing hypoxic, hyperoxic and normo-oxic patients there was no difference in 28 day mortality. Those with above normal oxygen levels tended toward longer hospital stays. The above normal oxygen cohort also were more likely to be intubated in the field.
This study fits with others showing around 20% of trauma patients arrive to our trauma bays over oxygenated. More research is needed to see the impact this has on care. Be mindful of over oxygenation especially in intubated trauma patients.

Traditional Medicare now covers < 50% of Medicare beneficiaries. It reimburses on a fee-for-service basis. For beneficiaries, it includes deductibles and coinsurance requirements that yield average annual out-of-pocket expenses measured in the thousands of dollars.
Medicare Advantage, the new alternative, has grown quickly. Plans typically promise beneficiaries fewer co-pays and more services. It relies on private insurers (think United, Blue Cross, Kaiser Permanente) to coordinate care and rein in costs. Subsidies to Medicare Advantage have helped spur growth, subsidies that mean costs per beneficiary for Medicare Advantage exceed those for traditional Medicare.
Which means Medicare still needs to figure out how to save money and remain viable while the US population over 65 grows.
When listening to a lecture about Medicare or reading a study that uses Medicare data, take a moment to ask “Which Medicare? Fee-for-service? Or Advantage?”

Let's not forget about hypercalcemia in the differential, especially in patients with a known malignancy! Many tumor types secrete a Parathyroid hormone (PTH)- related protein that mimics PTH and leads to high calcium levels.

When it comes to walking, recent research and public health strategies have focused on how much you do that helps. This idea frequently comes up in the form of the 10,000 step goal.
A recent study in the British Journal of Sports Medicine found that walking between 9,000 and 10,000 steps/day could reduce the risk of death by 39% and cardiovascular disease by 21%.
For both outcomes (all-cause mortality and incident CVD), approximately 50% of the benefit was achieved between 4,000-4,500 steps per day.
Study accessed data on greater than 72,000 individuals (avg age 61, 58% female) using accelerometer data over an average of 6.9 years.
Instead of volume, a recent study in the same journal looked at the benefits of walking speed.
The study looked at pooled data from 10 studies involving more than 500,000 people from the U.S., Japan and the U.K.
Walking speed definitions:
Easy or casual walking - less than 2 mph.
Average or normal pace was defined as 2-3mph.
A “fairly brisk” pace was 3-4 mph
A “brisk/striding walking pace” was greater than 4mph
Compared with people who walked at a casual/easy speed, those who walked at a normal/avg speed (2–3 mph) had a 15% lower risk of Type 2 diabetes.
Walking at a fairly brisk pace (3–4 mph) was associated with a 24% lower risk of Type 2 diabetes.
Walking at a brisk or striding pace (over 4 mph) was associated with a 39% reduced risk of Type 2 diabetes.
Globally, 537 million adults have type 2 diabetes, a figure that is expected to reach 783 million by 2045.
Take home: Consider recommending tips on walking pace and distance for our sedentary patient population to optimize health.

“I’m not going to the hospital, my father died in a hospital.”
In planning a study it’s a good practice to consider what confounding variables you may need to look out for.
Confounding variables are associated with the predictor (independent) and outcome (dependent) variables, but they are not in the causal chain. In the above example, disease is likely the predictor variable, death is the outcome variable, and going to the hospital is a confounder. Of course, this assumes the death was not iatrogenic; then the hospital would be in the causal chain.
Patients may be selected for interventions based on severity of disease, functional status, education level, and other factors, and these may be confounders.
Confounding can be addressed at the design stage, by:

Previous literature has shown that there is a survival difference between White and Black palpitations with regards to out of hospital cardiac arrest (OHCA) in the US.
This study looked at OHCA variables and outcomes among 5 racial/ethnic groups (White, Black, Asian, Hispanic, and Pacific Islander). Data was collected from the CARES registry from 3 racially diverse counties. The adjusted risk ratio for survival to hospital discharge was lower in all 4 other groups compared to patients where data entry identified the patient as White. The risk difference for positive neurologic outcomes was also lower among Black, Asian, Hispanic, and Pacific Islander patients.
When looking at variables associated with the cardiac arrests, there were differences between the groups with regards to response location and bystander CPR.
Bottom line: Cardiac arrest recognition and CPR education needs to be inclusive of all racial/ethnic groups and focus on areas where disparities exist.

Euglycemic DKA (eDKA) is a medical emergency requiring prompt attention. It is caused by an imbalance of insulin and glucagon leading to ketone accumulation (1-3). In addition to typical risk factors for DKA, those for eDKA include SGLT-2 inhibitor use and pregnancy, with 30% of DKA cases in pregnancy presenting euglycemic (4, 5).
eDKA presents with an anion gap metabolic acidosis, ketosis/ketonuria, & blood glucose less than 250 mg/dL.
Diagnosis requires ruling out other causes of anion gap metabolic acidosis, including toxic ingestions.
The cornerstone of eDKA management is ensuring enough dextrose to allow needed insulin administration to reverse ketone accumulation.

To obtain a posterior shoulder view: Have the patient sit up with the back of the bed down. Position the curvilinear probe in the posterior aspect of the shoulder with the probe parallel to the patient bed, at the level just below the scapular spine and the marker towards the patient's left. You can have the patient rotate their arm to help you visualize the movement of the humeral head.
In the normal anatomy, the humeral head should be at the level of the glenoid (this is a patient's left shoulder):
Locate the glenohumeral joint space. You can evaluate the GH joint for effusion, perform joint arthrocentesis/injection and look for signs of shoulder dislocation.
If you are evaluating for signs of a dislocation:
Posterior dislocation: the humeral head will be more SUPERFICIAL in the image than the scapular spine
Anterior dislocation: the humeral head will be DEEPER in the image than the scapular spine.

This was an observational study where ultrasound was used to evaluate if the diaphragm came into view at the 5th intercoastal space (ICS) at the midaxillary line in pediatric patients during maximal respiration. A convenience sample of pediatric patients who presented to the an academic pediatric emergency department was used.
In 10.3% of patients, the diaphragm crossed the 5th ICS during normal respirations and 27.2% crossed during maximal respirations. This was a more common occurrence on the right compared to the left. An increase in body mass index was also associated with an increased risk of the diaphragm crossing the during both tidal respiration and maximal respirations.
Bottom line: Using a blind insertion of a chest tube at the 5th ICS, midaxillary line in the pediatric patient poses a not insignificant risk of piercing the diaphragm. this study recommends using ultrasound prior to chest tube placement.

A study looking at patients over age 65 with head injuries from falls assessed the association of alcohol use with severity of injury. The alcohol use was self-reported which does limit the findings. The study found “Of 3128 study participants, 18.2% (n = 567) reported alcohol use: 10.3% with occasional use, 1.9% with weekly use, and 6.0% with daily use.” Those daily drinkers had a higher incidence of intercranial injuries.
The authors concluded: “Alcohol use in older adult emergency department patients with head trauma is relatively common. Self-reported alcohol use appears to be associated with a higher risk of ICH in a dose-dependent fashion. Fall prevention strategies may need to consider alcohol mitigation as a modifiable risk factor.”

This study, done out of Australia, examined the association between abdominal pain and severity of liver injury in patients presenting after acute acetaminophen overdose.
539 cases were identified where N-acetylcysteine was administered to patients with acetaminophen overdose. The investigators explored parameters including presence of abdominal pain, time post-ingestion, and peak ALT.
Patients less than 8 hours post overdose WITH abdominal pain were as likely to develop hepatotoxicity as those presenting WITHOUT abdominal pain. (OR=1.18 [0.07 to 19.4])
Patients presenting 8 or more hours post overdose WITH abdominal pain were as likely to develop hepatotoxicity as those WITHOUT abdominal pain (OR=1.28 [0.39 to 4.21])
