Abnormalities in serum phosphate levels are more prevalent in certain subsets of Emergency Department patients than in the general population. Patients with diabetic ketoacidosis, chronic obstructive pulmonary disease, alcoholism, malignancy, and renal failure are at increased risk. Multiple factors, including nutritional intake, medications, renal or intestinal excretion, and cellular redistribution, are potential etiologies. ⋯ Patients with severe or symptomatic hypophosphatemia should be treated with IV phosphate therapy (0.08-0.16 mg/kg over 6 h) and admitted for monitoring and subsequent serum electrolyte testing. Mild asymptomatic hyperphosphatemia is commonly managed in renal failure by limiting dietary intake and reducing absorption with phosphate-binding salts. Hemodialysis may be required for severe hyperphosphatemia with symptomatic hypocalcemia.

To record the outcome, with regard to infection rate, of patients with rattlesnake bites (RSBs) who do not receive prophylactic antibiotics, a prospective observational study was performed of patients with RSBs treated at our institution during a consecutive 18-month period. The inclusion criteria were RSBs <24 h old and completion of follow-up (telephone call, mail reply, medical toxicologist, or private physician examination) 7-10 days following envenomation. Fifty-six consecutive patients (Median age: 32.8 years [range 4-67 years]) were enrolled. ⋯ Fifty-three patients (100%) had extremity swelling and 38 patients (72%) had tender proximal lymph nodes. Of the 53 patients who completed the study, 3 (6%) received antibiotics from their primary care physicians at 7-10 day follow-up, with no cases (0%) of documented infection. Prophylactic antibiotics are not indicated in patients with rattlesnake bites.

Review Comparative Study
Computed tomography diagnosis of facet dislocations: the "hamburger bun" and "reverse hamburger bun" signs.
Unilateral or bilateral facet dislocations are difficult to diagnose. Computed tomography (CT) is being used more extensively to screen patients with suspected cervical vertebral injury. ⋯ Normal facet joints are oriented on a CT examination so that they resemble the sides of a hamburger bun. Facet dislocations upset this relationship and reverse the orientation of the "bun" halves to each other.

We report an atypical case of ovarian torsion, an uncommon cause of abdominal pain in a very young girl. She presented with intermittent episodes of groin and thigh pain over a 10-week period. ⋯ Despite the delay in diagnosis, the ovary was preserved. Despite its rarity, ovarian torsion must be considered in the differential diagnosis of abdominal pain in young girls.
