Four patients with fulminant myocarditis (two males and two females, age 21-67 years old) were examined during 1995-2001. Fulminant myocarditis was diagnosed based on clinical features, abnormal electrocardiographic and echocardiographic findings, and increased serum enzyme levels. In three of four cases, the diagnoses were confirmed histologically in autopsy. All four patients had flu-like symptoms and fever at the start. One patient died suddenly next day. Other three patients went into cardiogenic shock five and seven days after the onset of symptoms and hospitalized, and treated with temporary pacing, steroid pulse therapy, catecholamine (in all three patients) and percutaneous cardiopulmonary support : PCPS (in one patient), but they died within ten days. Electrocardigrams showed ventricular escape rhythm, ST elevation associated with Q wave, and low voltage of the QRS complex. Markedly increased serum enzyme levels, severe metabolic acidosis and disseminated intravascular coagulation were thought to be indicative of poor prognosis. Early recognition of cardiac involvement and using of PCPS without hesitation in an acute phase could improve the outcome of fulminant myocarditis.

OBJECTIVEThe aim of this study was to establish reference concentrations of urinary strontium by inductively coupled plasma atomic emission spectrometry (ICP-AES).

METHODSFor the determination of strontium, urine samples were collected from healthy Japanese (n=146; 115 males, 31 females; mean age, 33±9 years; age range, 18 to 58 years). The urine samples stored at or below -20°C were thawed with incubation at 40°C for 30 min and sediments were dissolved by vigorous shakings. Then, the samples were centrifuged at 3000 g for 5 min, and the supernatant was directly aspired into a P-5200-3600/1200 ICP-AES system from Hitachi Ltd., Tokyo, Japan.

RESULTSA steeper increase in the S/N ratio and a good effective linearity of the calibration line was obtained at 407.771 nm in the range of 0-300 μg/L strontium standard solution. Urine samples having the same background signal as that of 18 MΩ cm ultrapure blank water, a good correspondence of the single peak pattern of the spectra, accuracy and precision of spike recovery were also confirmed. Urinary strontium concentrations showed a log-normal distribution and a geometric mean concentration of 143.9 μg/L, with 5-95% confidential interval of 40.9-505.8 μg/L.

CONCLUSIONThe results of this study will be useful as guidelines for the biological monitoring of strontium in normal subjects and in individuals therapeutically or environmentally exposed to strontium.
