Febrile seizures occur in children 6 months through 5 year olds. A complex febrile seizure occurs when the seizure is focal, prolonged (> 15 min), or occurs more than once in 24 hours.
The prevalence of bacterial meningitis in children with fever and seizure after the H flu and Strep pneumomoniae vaccine was introduced is 0.6% to 0.8%. The prevalence of bacterial meningitis is 5x higher after a complex than simple seizure.
From the study referenced, those children with complex febrile seizures who had meningitis all had clinical exam findings suggestive of meningitis. More studies are needed to provide definitive guidelines about when lumbar punctures are needed in these patients.

In patients presenting to the ED with suicidal ideation, physicians should not use currently available risk-assessment tools in isolation to identify low-risk patients who are safe for discharge. The best approach to determine risk is an appropriate psychiatric assessment and good clinical judgment, taking patient, family, and community factors into account. (Level C Recommendation, based upon the quality of the research.)

Catastrophic Antiphospholipid Syndrome (CAPS):
A life-threatening “thrombotic storm” of multi-organ micro & macro thrombosis in patients with antiphospholipid syndrome (known or unknown).
Triggered circulating antibodies (usually by infection, but can be prompted by malignancy, pregnancy, and lupus itself) cause endothelial disruption and inflammation leading to prothrombotic state, commonly with SIRS response.
Mortality is high at an estimated 40%.
Confirm diagnosis with antiphospholipid antibody titers.
Treat ASAP with unfractionated heparin, corticosteroids, and Hematology consultation for plasma exchange and/or IVIG.

- It most commonly occurs in patients with preexisting pituitary adenomas, but 3 out of 4 patients with pituitary adenomas are unaware of their diagnosis.
- Patients may acutely present with thunderclap headache, with or without visual field deficits or cranial nerve dysfunction. They may also have meningeal symptoms due to extravasation of blood into the subarachnoid space.
- Endocrine dysfunction is common but not readily diagnosed in the ED.
- Symptoms may be triggered by some hormonal treatments (e.g. GnRH agonists for prostate CA), head trauma, angiographic procedures, or anticoagulation therapy.
- CT is diagnostic in only one-third of cases, but can reveal the intrasellar mass in 80% of cases, and therefore should be the initial test. Blood may be missed in subacute cases.
- MRI is the test of choice, with a sensitivity of over 90%.
Bottomline: Keep pituitary apoplexy in your differential when considering SAH or meningitis, especially in the presence of risk factors, and have a low threshold to order an MRI.

Patients with psychiatric disorders are found globally, with a recent global burden of disease estimate that mental illness accounted for 32.4% of years lived with disability and 13.0% of disability-adjusted life-years.
The American College of Emergency Physicians just published a methodological rigorous clinical policy entitled “Critical Issues in the Diagnosis and Management of the Adult Psychiatric Patient in the Emergency Department.”
One question they sought to answer was “In the alert adult patient presenting to the ED with acute psychiatric symptoms, should routine laboratory tests be used to identify contributory medical conditions (nonpsychiatric disorders)?”
Their assessment was: “Do not routinely order laboratory testing on patients with acute psychiatric symptoms. Use medical history, previous psychiatric diagnoses, and physician examination to guide testing.” This was a Level C recommendation, based upon the quality of the research.
Bottom Line: Current literature does not support routinely ordering laboratory testing on patients with acute psychiatric symptoms. However, the quality of the evidence was not strong and local clinical context should be considered.

Early Oseltamivir Treatment in Influenza in Children1-3 Years of Age: A Randomized Controlled Trial
A study in 2010 out of Finland by Heinonen, et al showed that if given in the first 12 hours of symptom onset to otherwise healthy pediatric patients between the age of 1-3 years:
- decrease incidence of acute otitis media by 85%
- no difference if given within 24 hours
Among children with influenza A, oseltamivir started within 24 hours of symptom onset
- shortened medium time to resolution of illness by 3.5 days (3.0 versus 6.5) in all children
- shortened median time to resolution of illness by 4.0 days in UNvaccinated children
- Reduced parental work absenteeism by 3 days
* no differences were seen in children with influenza B *
Limitations***
- Single Center study in Finland
- The authors received support from the drug manufacturer
- The sample size of children with confirmed influenza cases with small (influenza A: 79, influenza B: 19)
Takeaway:
If you have a patient between the age of 1-3 years with very early symptoms concerning for flu, a positive rapid influenza A test could allow you to cut her symptoms by 3 days, prevent complications, and allow parents to go back to work sooner.

Patients with severe salicylate poisoning may require endotracheal intubation due to fatigue from hyperventilation or mental status change.
A previously published study (Stolbach et al. 2008) showed that mechanical ventilation increases the risk of acidemia and clinical deterioration.
A small retrospective study investigated the impact of hemodialysis (HD) in intubated patients with salicylate poisoning.
Findings:
53 cases with overall survival rate of 73.2%
In patients with salicylate level > 50 mg/dL
- No HD: 56% survival (14/25)
- HD: 83.9% survival (0/9)
If salicylate level > 80 mg/dL
- No HD: 0% survival (26/31)
- HD: 83.3% survival (15/18)
Bottom Line:
There is moratality benefit of HD in intubated salicylate-poisoned patient.

Improving Resuscitation Performance
- Resuscitating the critically ill patient can often be quite stressful.
- Stress has been shown to decrease the quality and effectiveness of decisions, decrease the amount of information a person can process, and lead to short-term memory deficits.
- Recently, there has been emphasis on the use of performance-enhancing psychological skills (PEPS) to allow providers to think clearly, maintain situational awareness, recall important information, and perform skills efficiently.
- A recent article highlights 4 key elements of an EM model for PEPS that can be used to improve performance in resuscitations.
- Breathe - consider tactical breathing
- Talk - positive instructional or motivational self-talk
- See - visualize the steps of a procedure before actually performing it
- Focus - use a trigger word as a prompt to shift attention to a prioritized task

PCL injuries can sometimes have involvement of the posterolateral corner (PLC)
The dial test can be used to diagnose posterior lateral instability and help differentiate it from isolated PCL injuries
The dial test involves comparing the amount of external rotation of the lower leg at the knee while the knees are in 30° and in 90° of knee flexion.
https://www.youtube.com/watch?v=rnk62Y-nDSQ
An isolated injury to the posterolateral corner will result in more than 10° of external rotation in the injured knee that is present at 30° but not at 90° of knee flexion.

Ventricular shunt (VP) malfunction can be severe and life-threatening and evaluation has typically included a dry CT brain and a shunt series which includes multiple x-rays of the skull, neck, chest and abdomen. The goal of this study was to decrease the amount of radiation used in the evaluation of these patients since these patients will likely present many times over their lifetime. Several institutions have more towards a rapid cranial MRI, however, this modality may not be readily available.
This multidisciplinary team decreased the CT scan radiation dose from 250mA (the reference mA in the pediatric protocol at this institution) to 150 mA which allows for a balance between reducing radiation exposure and adequate visualization of the ventricular system. They also added single view chest and abdominal x-rays.
The authors found that after implementing this new protocol, there was a reduction in CT radiation doses and number of x-rays ordered with no change in the return rate.

Vaginal douching is a common and potentially dangerous practice. Women engage in this practice predominately for personal hygiene reasons but also with the false belief it will prevent or treat infections and for contraception. Numerous public health agencies and medical societies discourage douching as it has been associated with many adverse outcomes including pelvic inflammatory disease, bacterial vaginosis, cervical cancer, low birth weight, preterm birth, human immunodeficiency virus transmission, sexually transmitted diseases, ectopic pregnancy, recurrent vulvovaginal candidiasis, and infertility.
An increasing fad is the use of intravaginal detox products. Claiming to enhance female health by removing toxins, these mesh cloth-covered balls containing herbs such as mothersworth, osthol, angelica, borneol, and rhizoma, not FDA-approved, are inserted into the vagina for 3 days. Clinical experience demonstrates these products decompose into numerous pieces which become scattered retained intravaginal foreign bodies, cause mucosal irritation, and thereotically could serve as a nidus for serious infections.

When surveyed, half of general medicine patients interviewed stated that they would prefer to have a loved one present if they were to develop cardiac arrest and require CPR. So far, studies have demonstrated that…
Allowing family presence during CPR is associated with the following benefits to family members:
- Decreased rates of PTSD-related symptoms
- Decreased scores on anxiety and depression scales
- Decreased incidence of complicated grief
- Decreased incidence of family member regret (at having been present vs absent during CPR)
And is NOT associated with a difference in:
- Survival rate
- Duration of resuscitation efforts
- Type or dose of administered medications
- Number of shocks delivered
- Emotional stress level of medical providers
- Occurrence of medicolegal conflict

Hydrogen peroxide (H2O2) is a common household liquid that is used for wound irrigation/antiseptic and cosmetic purposes. The concentration of household product is 3% to 5% and is considered to be relatively safe except in large volume ingestion.
High-concentration H2O2 (>10%) is commercially available as “food grade” (35%) that is diluted for household use or for alternative medicine therapy (i.e. hyperoxygenation).
Ingestion of high-concentration of H2O2 can result in caustic injury as well as ischemic injury from gas embolism.
Ingestion of 1 mL of 3% H2O2 produces 10 mL of O2 gas while 1 mL of 35% H2O2 produces 115 mL of O2 gas.
Common symptoms/findings of H2O2 ingestions includes:
- Nausea/vomiting
- Abdominal pain due to gas in portal venous system
- Caustic injury of GI track (ingestion of > 10% H2O2)
- Arterialization of O2 gas result in end-organ injury (e.g. CVA)
A retrospective review of >10% H2O2 ingestion from National Poison Data System showed:
- 13.9% developed gas embolic event
- 6.8% experienced permanent disability, including 5 deaths.
Management
- Minor symptoms: primary supportive
- CT ABD/Pelvis should be considerd if abdominal pain is present
- If significant gas is present in portal vein or evidence of end-organ injury (i.e. CVA), HBO therapy is recommended (limited evidence).
- Endoscopy should be considered in concentrated H2O2 ingestion to evaluate for caustic injury.

Idiopathic osteonecrosis of the femoral head
Children as young as 2 or as old as 12 but generally 4 to 8 (worse in older children)
Fare better than adults with osteonecrosis of femoral head
1 in 10,000
4-5x more common in males, much less common ini African Americans
Unilateral femoral head involvement 90% of the time (Bilateral 10% of the time)
Long term consequences are deformity and arthritis
Typical presentation: Subacute limping for weeks (Painless)
As activity worsens limp, it is maximal at the end of the day (Intermittent)
As in adults with hip pathology, IF pain is reported, it is located at the upper anterior thigh and groin
On examination, look for restriction in range of motion of the hip (compare with contralateral side)
May only present with mild to moderate decreased range of motion of the hip
30 versus 60 degrees for example
ABduct both legs with pelvis in neutral OR Place one hand on contralateral pelvis and ABduct affected leg with other hand.

Cholera is an acute diarrheal disease that can kill within hours if left untreated.
Rising cholera, diarrhea and malnutrition is a deadly combination in war torn countries, such as Yemen, South Sudan, Somalia and Sudan, especially for children.
Yemen currently has the worst outbreak globally, with over 260,000 suspected cases and over 1,600 deaths. In Yemen:
o Half the suspected cases are children
o A quarter of the deaths are among children
Bottom Line:
Cholera remains a major cause of morbidity and mortality globally, especially in areas of conflict.
