Plasma-Lyte A outperformed 0.9% NaCl for rehydration in children with acute gastroenteritis showing a more rapid improvement in serum bicarbonate levels and dehydration scores.
--Massive PE is defined as PE with obstructive shock (hypotension [SBP <90] or end-organ malperfusion)
--Consider venoarterial (VA) ECMO in massive PE for hemodynamic support, particularly prior to intubation
--VA ECMO may prevent intubation/mechanical ventilation, surgical intervention, systemic and local thrombolysis

US, Canadian and European critical care and toxicology societies recently published a consensus recommendation is the management of CCB poisoning.
Bottom line:
1. First line therapy remains unchanged: IV calcium, atropin, high-dose insulin (HIE) therapy, vasopressor support (norepinephrine and/or epinephrine).
2. Refractory to first line therapy: increase HIE, lipid-emulsion, transvenous pacemaker
3. Refractory shock, periarrest or cardiac arrest: Above (#1 & #2) plus ECMO if available.

Oxygen-ICU Trial
57 year-old female with history of bilateral lung transplants presents with fever, and 2 days of a painful, red, bumpy rash over the left labia and left buttock, but also notes a small tender area on the plantar surface of the left foot.
Below is a figure depicting the location of the rash, as well as a photo of her foot.

Recurrence depends on age and activity level
27% if >30yo and 72% if <23yo
Surgical Recommendations:
Large bony Bankart lesion, glenoid or humeral head defect >25%, recurrent instability, event near the end of season
Non surgical return to play:
If event occurs at beginning/early in season
Rehabilitation for 2 to 3 weeks (most return to play in this time frame)
Immobilization for 3 to 7 days in simple sling, gentle range of motion, cryotherapy
Physical therapy to strengthen dynamic stabilizers
Shoulder stabilization brace for non overhead throwing and contact sports
Fall clean up = Poison Ivy, oak, sumac (Toxicodendron species) which is ubiquitous in North America but it can also be found in British Columbia, Mexico and in parts of Asia. These plants are truly the scourge of outdoor enthusiasts and agricultural workers responsible for up to 40 million cases of miserable often temporarily incapacitating rashes annually.

What is the FASH Exam?
Submitted by Dr. Laura Diegelmann
The delta gap is a measurement intended to assess for mixed acid-base disorders. A straightforward alternative, the strong ion difference (SID), allows for a quick and simple assessment of any non-gap acidosis or alkalosis that may be present.
The SID is simply the difference between the strong cations (Na+, K+, Mg+, Ca+) and the strong anions (Cl-) present in the serum. The abbreviated SID is the difference between the serum sodium and serum chloride levels (approximately 138-102). Values typically range from 36-40 mg/dl. Values less than 36 denote the presence of some degree of hyperchloremic, non-gap, acidosis. While values greater than 40 demonstrate the presence of hypochloremic, non-gap, alkalosis. And while on rare occasions, variations in albumin or elevated levels of cations other than sodium can lead you astray, the SID is as accurate as a delta gap at identifying mixed acid-based disorders without the added mathematical complexity.
A 41 year old female presenting with intermittent RUQ abdominal pain for 1 week. An ultrasound of the right upper quadrant was performed. What is the diagnosis ?

Application to clinical practice:
A 12 year old male who recently started middle school presents to the ED with a rash in the periumbilical region that has been developing over the last few weeks. The rash is scaly, somewhat itchy, but otherwise benign appearing. The patient has no known medical conditions other than eczema, and is otherwise well. What is the diagnosis?

You have a patient in whom you suspect meningitis, but he is on warfarin for a history of pulmonary embolism. You started empirical antibiotics. His INR is 2.6, and you want to do a lumbar puncture (LP) to confirm your diagnosis. Can you use Prothrombin Complex Concentrate to lower his INR and safely perform the LP?
Take Home Point:
Using PCC to lower INR to enable LP is relatively safe and effective in patients on vitamin K antagonists. The dose used was individually determined by the physician according to initial INR.
Limitation:
This is a retrospective study, with no control group. One patient (2.7%) had a myocardial infarction that was “possibly related” to the PCC administration.
TAKE HOME POINTS:
-- High chloride load is associated with adverse outcomes in large-volume resuscitation (>60mL/kg in 24h), including increased risk of death [1]
-- Avoid supraphysiologic chloride solutions (i.e. normal saline) when resuscitation volumes are likely to exceed 60mL/kg (e.g. sepsis, DKA)
22-year-old male with history of autism, mental retardation who is non-verbal presents with abdominal pain and vomiting for one day. Patient was found clutching his abdomen and moaning. What's the diagnosis?
Retroperitoneal hemorrhage
The pathophysiology is unknown. Some hypothesize that occult vasculopathy and arteriosclerosis of the small vessels in the retroperitoneum may render them friable and therefore prone to rupture. This can be seen in minor trauma in sports and forceful vomiting or coughing. Spontaneous bleeding starts at the microvascular level, and large vessels become disrupted or stretched as the hematoma enlarges.
Retroperitoneal hemorrhage occurs in a variety of clinical circumstances, including spontaneous hemorrhage into a pre-existing benign adrenal cyst or bleeding from a left inferior phrenic artery, tumors of the adrenal gland and kidney, rupture of any blood vessel (most commonly infrarenal aorta); percutaneous interventions (such as cardiac catheterization), trauma, and polycythemia vera,
It is most commonly seen in association with patients with bleeding abnormalities, in HD patients and with anticoagulation therapy,. Risk is much greater with unfractionated heparin therapy than with warfarin. In most of the heparin patients studied, their coagulation parameters were in the therapeutic range.
Patients may present to the non acute area of the ED with back, lower abdominal or groin discomfort, Over time, this may progress to hemodynamic instability, and a fall in hemoglobin, Early identification is crucial to improving patient morbidity and mortality. Early symptoms depend on the location of the bleeding.
Hematoma near or within the iliopsoas muscle usually presents as femoral neuropathy (groin pain or leg weakness).
Femoral neuropathy caused by retroperitoneal hematoma can present with sudden onset severe pain in the affected groin and hip, with radiation to the anterior thigh and the lumbar region. This can easily be missed as the presentation is similar to a pulled msucle or strained hip/back. Iliopsoas muscle spasm often results in the characteristic flexion and external rotation of the hip, and any attempt to extend the hip will result in severe pain. Over time, pain and parasthesia in the antero-medial thigh and leg is seen.
Non –communicable diseases (NCDs), primarily cardiovascular diseases, cancer, respiratory diseases and diabetes, are significantly increasing globally. According to the WHO, cardiovascular diseases alone account for 17.5 million deaths annually- the most of any NCD.
If someone has return of spontaneous circulation after cardiac arrest, but does not have ST-elevations on their post-arrest ECG, should you emergently activate the cath lab?
In a just released systematic review and meta-analysis in Resuscitation, Dr. Millin and colleagues found that almost one third of patients successfully resuscitated without ST elevation on their ECG had a culprit lesion that would benefit from emergent intervention.
Bottom Line: While this is not definitive proof to emergently activate the cath lab for a NSTEMI, it is another strong indication that post cardiac arrest patients without ST elevation may benefit from emergent percutaneous coronary intervention.
