The unpredictable nature of patient visits poses considerable challenges to the staffing of emergency department (ED) medical personnel. There is a lack of common physician usage parameters at present. ⋯ A queueing model was built to model traffic intensity of physicians and patients, the physician utility trend disclosed the fluctuation of manpower utility. The estimated parameters serve as important factors for developing tailored staffing policies for minimizing ED waiting and improving ED crowding.

Pathological laughter is defined as uncontrollable and inappropriate laughter unrelated to an emotion or a mood. This symptom can reveal a stroke. ⋯ We described the case of a 57-year-old patient who presented to the emergency department 2 h after a sudden onset of left hemiparesis preceded by pathological laughter. The left motor weakness was very discrete and underestimated because of severe behavioral changes, that is, laughter, joviality, and motor restlessness. Despite abnormal brain imaging results, symptoms were considered as atypical to evoke a stroke. The patient did not receive intravenous thrombolysis. Brain magnetic resonance imaging performed 2 days after admission confirmed the diagnosis of stroke. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Emergency physicians are at the forefront of stroke management. They should be aware that the initial symptom of a stroke can be atypical and lead to misunderstanding the diagnosis. Because the treatment of stroke requires the fastest care, it is important for emergency physicians to know that sudden behavioral troubles and pathological laughter can reveal strokes.

Malpractice in emergency medicine is of high concern for medical providers, the fear of which continues to drive decision-making. The body of evidence evaluating risk specific to emergency physicians is disjointed, and thus it remains difficult to derive cohesive themes and strategies for risk minimization. ⋯ There are consistent diagnoses that are associated with increased litigation incidence. A combination of mitigation approaches may assist providers in mitigation of malpractice risk.

Autoamputation of the appendix is a condition associated with the Ladd's procedure, a pediatric surgical technique for correction of intestinal malrotation. A 4-year-old male patient with a history of a Ladd's procedure performed as a newborn was brought in by his mother for "passing intestine" just prior to arrival. She reported that for several weeks her son had intermittent, crampy abdominal pain that resolved after the unusual-appearing bowel movement. After reviewing an image of the bowel movement, and in consultation with pediatric surgery, it was concluded that the patient had passed a devascularized appendix in his stool immediately prior to arrival. ⋯ A 4-year-old boy with a past medical history of heterotaxy syndrome (inversion of the thoraco-abdominal organs), a double outlet right ventricle, and Ladd's procedure presented to the Emergency Department (ED) after "passing intestine" in his stool. Close examination of the photo demonstrated a tubular structure with taenia, consistent with an appendix. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Autoamputation of the appendix is an uncommon presentation in the ED. Passing a devascularized appendix is a benign condition and can present with weeks of intermittent abdominal pain that resolves with passage of appendix in the stool. Remnants of the appendix can remain within the intestinal lumen years after the Ladd's procedure. Emergency physicians with a general awareness of this rare phenomenon can confidently make the diagnosis and reassure worried parents.

Unusual Complications From Babesia Infection: Splenic Infarction and Splenic Rupture in Two Separate Patients.
Babesiosis is a zoonotic parasitic infection transmitted by the tick, Ixodes scapularis. Splenic infarct and rupture are infrequent complications of Babesia parasitemia, and have not been previously reported in the emergency medicine literature. ⋯ We present two separate cases seen within 1 month at our institution: a case of splenic rupture and another case of splenic infarction due to Babesia parasitemia. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Babesia infection in humans is increasingly prevalent in both the United States and worldwide, and clinical manifestations can range from subclinical to fulminant infections. An unusual but potentially fatal complication of babesiosis is splenic infarctions and rupture. Due to the endemicity of this parasite, a careful history and level of suspicion will enable the emergency physician to consider and test for babesiosis in patients with splenic injuries and without obvious traditional risk factors.
