The outcome of Graves' disease after treatment with antithyroid drugs (ATDs) varies widely among countries, and large-scale studies in Asia are rare. We investigated the associations of various clinical and laboratory features with the outcome of ATD therapy for Graves' disease in Taiwan. A total of 210 patients (177 women, 33 men; mean +/- SD age, 41.7 +/- 15.1 yr) treated with ATD in Taiwan were included. ⋯ Combination therapy with L-T4 yielded similar results to those achieved with ATD treatment alone. In conclusion, the relapse rate of Graves' disease after ATD treatment in Taiwanese patients was high, especially in those with a history of recurrence. The treatment duration and drug regimen did not affect the outcome.

Comparative Study
Anesthesia for pediatric herniorrhaphy or hydrocelectomy: comparison of propofol/ketamine and thiopentone/halothane.
Total intravenous anesthesia has recently become available for ambulatory surgery. It has the advantages of decreased air contamination from volatile anesthetics and decreased exposure of operating room personnel to volatile anesthetics. The purpose of this study was to compare the anesthetic properties of propofol/ketamine (total intravenous) anesthesia and thiopentone/halothane (intravenous and gaseous) anesthesia for herniorrhaphy or hydrocelectomy in children. ⋯ We conclude that propofol/ketamine allows patients to maintain spontaneous natural airway breathing during anesthesia, and its analgesic and anesthetic effects are comparable to those of thiopentone/halothane. Propofol/ketamine is appropriate for pediatric herniorrhaphy and hydrocelectomy. It can be recommended for pediatric ambulatory surgery.

We retrospectively evaluated the outcome and the risk factors for mortality among extremely low birth weight (ELBW) infants born at National Taiwan University Hospital. The records of all live-born infants with body birth weight of less than 1,000 g from January 1, 1993, to December 31, 1996, were evaluated. Infants with major anomalies or whose parents refused resuscitation were excluded from the analysis. ⋯ Cox regression analysis of survival showed that Apgar score at 1 minute (p = 0.0063), pulmonary hypertension (p = 0.012), and severe intraventricular hemorrhage (p = 0.0031) were the most important factors associated with mortality. Though the outcome of ELBW infants in our institute seems poorer than in some more developed countries, it is improving. The prognosis for ELBW infants of 24 to 25 weeks' GA remains guarded under our present care.

Femoral and sciatic nerve blocks have been used occasionally for unilateral total knee arthroplasty (TKA). In order to evaluate the effectiveness of this technique, combined femoral 3-in-1 and sciatic nerve blocks were performed in 20 cases of TKA, by the same surgeon. This surgeon also performed unilateral TKA under spinal anesthesia in another 20 cases. ⋯ Ten of the 20 patients who had spinal anesthesia complained of postoperative urinary retention, while none of those who had nerve block had this complaint. Neither group experienced postpunctural headache, neurovascular damage, or drug-over-dose toxicity. We conclude that combined femoral 3-in-1 and sciatic nerve block is an effective anesthetic alternative for unilateral TKA.

Case Reports
Extracorporeal membrane oxygenation in treatment of cardiogenic shock caused by acute myocarditis.
We report a 31-year-old woman with acute myocarditis who was transferred to our hospital because of rapidly progressive cardiogenic shock unresponsive to infusion of high doses of inotropic agents and intraaortic balloon pump support. Upon arrival at our hospital, extracorporeal membrane oxygenation (ECMO) was immediately established through a right femoral venoarterial route by percutaneous cannulation; the blood flow of ECMO was maintained at around 2,100 mL/min. ⋯ The patient was maintained on ECMO for 90 hours then successfully weaned from the machine without major complications. Our experience suggests that ECMO can be used for temporary mechanical circulatory support in patients with cardiogenic shock due to acute myocarditis.
