Comparative Study
Ethnic comparison of haloperidol and reduced haloperidol plasma levels: Taiwan Chinese versus American non-Chinese.
Steady-state haloperidol (HAL) and reduced HAL (RHAL) plasma levels were measured in Chinese and non-Chinese schizophrenic patients. The patients (n = 38) were matched according to age (+/- 1 yr) and by HAL dose. In general, Chinese patients had higher mean plasma HAL levels and lower RHAL/HAL ratios compared to non-Chinese patients (23.6 +/- 14.9 ng/ml versus 17.1 +/- 10.1 ng/ml, p less than 0.05; 0.52 +/- 0.44 versus 0.82 +/- 0.62, p less than 0.05). ⋯ RHAL/HAL ratios were generally lower in the Chinese patients than in the non-Chinese patients, with a strong trend toward the significance level in the 20 mg and 30 mg groups (0.22 +/- 0.13 versus 0.58 +/- 0.57, p = 0.066 and 0.43 +/- 0.26 versus 0.71 +/- 0.34, p = 0.062). This study further suggests the possibility of different metabolic rates between Chinese and non-Chinese patients. Possible differences in the enzyme systems which relate to the metabolism of HAL and RHAL between Chinese and non-Chinese populations are discussed.

Prevalence of antibody to hepatitis C virus in pregnant Taiwanese.
To assess the prevalence of an antibody to hepatitis C virus (anti-HCV) in pregnant women in Taiwan, and elucidate whether or not there is superinfection of the hepatitis B virus (HBV) in such cases, we investigated two independent groups of pregnant women. Group A included 294 without serum alanine aminotranferase (ALT) screening, and group B included 171 pregnant women with an abnormal ALT level (greater than 45 IU/L) who were recruited from 9,523 pregnant women screened for ALT. Blood samplings were taken at early gestation and each serum sample was tested with an HCV EIA kit for anti-HCV. ⋯ Therefore, the prevalence of anti-HCV in pregnant women by current assay in Taiwan is 0.34% without ALT screening, but increases to 2.3% among abnormal ALT cases. The prevalence rate is less than the rates reported in other countries. If confirmed by subsequent study, the results suggest that infection with HCV is low among healthy young females in Taiwan today.

The prognostic value of blood glucose in patients with acute stroke.
We prospectively studied levels of blood glucose and glycohemoglobin, and their correlations with types, severity, and prognosis of stroke in 37 patients with brain infarction (BI) and 35 patients with brain hemorrhage (BH). We found that in the BH group, patients with an elevated glucose level due to stress, diabetes, or both, had a lower consciousness level on admission, larger hematoma size, higher incidence of rupture into the ventricles, and a worse 1-month outcome than patients with a normal glucose level (p less than 0.05). ⋯ However, it seems to be the severity of the stroke, not the hyperglycemia, that causes the poor outcome. Hyperglycemia may be an epiphenomenon of stroke severity.

To study the causes of burn injuries and the nature of their medical treatment, we investigated the medical histories of hospitalized patients admitted to the burn center of Taipei City Ho-Ping Hospital from June 6, 1983 to June 6, 1987. Additionally, a phone interview follow-up on recovery conditions was made. Among the 300 patients admitted, the majority (53.7%) were burned by scalding water, while fire was the second most common cause of burns. ⋯ Those with severe burns average 26.5 days. Half (50.7%) of the patients recovered by the time they left the hospital. Examining the death rate by type of burn, we found that the death rate for chemical burns was the highest (10.34%), while the rate was lowest for scalding.(ABSTRACT TRUNCATED AT 250 WORDS)

Hemodynamic and respiratory parameters were continuously monitored in 45 septic shock patients, 15 of whom developed adult respiratory distress syndrome (ARDS). Low oxygenation index (OI = PaO2/FIO2), pulmonary artery hypertension (high mean pulmonary artery pressure, MPAP) and elevated pulmonary vascular resistance (PVR) were observed in all ARDS, as well as in non-ARDS septic patients, as a baseline. These same pulmonary factors were compared between those who survived and those who died during the first few days (early fatalities) in both the ARDS group (5 patients) and the non-ARDS group (8 patients). ⋯ In the non-ARDS group, the MPAP of the early fatalities was significantly lower (p less than 0.01) than that of survivors, but their OI was not significantly lower. PVR, when compared between groups (ARDS versus non-ARDS) or between subgroups within each group, was elevated concurrently with the elevation of MPAP. It is concluded that patients with septic shock and ARDS who show a severely depressed OI and a modestly elevated MPAP and PVR during the first few days can be predicted to have a poor outcome.
