Intravenous lipid rescue therapy (LRT) may be implemented to attenuate drug toxicity. Little is known about LRT interference with laboratory tests in overdose settings. A 54-year-old man with a history of depression consumed unknown amounts of diphenhydramine, amitriptyline, and acetaminophen (APAP). ⋯ This conclusion is limited by the lack of repeat measurement of liver enzymes or measurement of serum lipid levels. Lipid rescue therapy may cause lipemia that interferes with the assay for liver enzymes. Suspected abnormal laboratory values should be repeated, or other techniques can be used to remove lipemic interference.

Patients with pelvic fracture usually require transfers to trauma centers for additional advanced treatment. Patient safety during the transfer should always be a priority. The noninvasive pelvic circumferential compression device (PCCD) can reportedly provide a tamponade effect, which reduces hemorrhage. In the present study, we evaluated the feasibility and efficiency of PCCD in patients with pelvic fracture who required transfer to trauma centers. ⋯ Pelvic circumferential compression devices benefit patients with pelvic fracture who need to be transferred to trauma centers. Pretransfer PCCDs appeared to be a feasible and safe procedure during the transfer. In discussions between the referring physicians and the receiving physicians, we recommend using pretransfer PCCDs.

It is known that patients with convulsion often present hyperammonemia. The elevation of ammonia levels in convulsion is considered to occur along with extensive muscle contractions, but the details remain unclear. In emergency pathologies, such as cardiopulmonary arrest or hemorrhagic shock without muscle contraction, red blood cells are known to produce ammonia through acidosis, leading to hyperammonemia. A similar effect would be considered to be involved in idiopathic epileptic seizure patients as well. ⋯ Idiopathic epileptic seizures can present with prominent hyperammonemia with acidosis. Because high ammonia level in epileptic seizure was strongly correlated with pH and BE, we speculate that hyperammonemia is not only because of extensive muscle contractions but is also related to ammonia production in the red blood cells through acidosis like other emergency conditions.

We report a rare case of rhabdomyolysis caused by peripheral T-cell lymphoma (PTCL) in skeletal muscle. A 62-year-old man was admitted with complaints of sudden muscle weakness. Laboratory abnormalities were identified including markedly elevated creatinine-phosphokinase, peaking at 62,640 IU/L and serum creatinine (Cr) at 5.0 mg/dL. ⋯ Finally, he was diagnosed with rhabdomyolysis caused by PTCL. Methylprednisolone pulse therapy markedly improved his general condition and renal function (Cr 1.48 mg/dL), and computed tomography scans revealed that tumorous swelling was greatly diminished. Except when the cause of rhabdomyolysis is readily apparent, such as in cases of trauma, drug and thrombophlebitis, one should consider that rhabdomyolysis may be a sequel of lymphoma.

Observational Study
A new method to detect cerebral blood flow waveform in synchrony with chest compression by near-infrared spectroscopy during CPR.
The objective of the study is to demonstrate the utility of near-infrared spectroscopy (NIRS) in evaluating chest compression (CC) quality in cardiac arrest (CA) patients as well as determine its prognosis predictive value. ⋯ Near-infrared spectroscopy reliably assesses the quality of CCs in patients with CA demonstrated by synchronous waveforms during CPR and possible prognostic predictive value, although further investigation is warranted.
