[A search for the risk factors for hiccups and evaluation of antiemetic therapy in CDDP-based chemotherapy, using cluster analysis].
Hiccups are often observed in patients treated with cisplatin(CDDP)-based chemotherapy. It has been reported that gender and specific dosages of CDDP and antiemetic drugs(e.g., dexamethasone and 5-HT3 receptor antagonist)using standard therapy are major risk factors in the onset of hiccups. Recently, aprepitant has been added to the antiemetic therapy in CDDP-based chemotherapy. ⋯ Our analysis indicated that aprepitant was not a major risk factor for the onset of hiccups in the high CDDP dose group(≥70 mg/m(2)). However, an effect of antiemesis was confirmed in the standard therapy with aprepitant. In conclusion, we suggest that aprepitant is effective for CINV, without causing the onset of hiccups in patients treated with high-dose CDDP-based chemotherapy.

[A study on the antiemetic effect and extrapyramidal symptoms of prochlorperazine versus perospirone for the control of nausea and vomiting due to opioid introduction].
Prochlorperazine is often used to prevent opioid-induced nausea; however, this drug causes extrapyramidal symptoms. It is important to determine the incidence of such symptoms and identify coping mechanisms because these symptoms induce intense and possibly life-threatening patient suffering. The purpose of this study was to determine the incidences of nausea and extrapyramidal symptoms associated with the use of prochlorperazine and perospirone as preventive antiemetics when initiating opioid treatment(a sustained-release tablet of oxycodone at a dose of 10 mg/day)and to compare the benefits of the 2 drugs. ⋯ The results showed that the incidence of nausea and vomiting was 8. 0% for the prochlorperazine group and 4. 0% for the perospirone group, and this difference was not statistically significant; however, the incidence of extrapyramidal symptoms was significantly higher for the prochlorperazine group(14%)than for the perospirone group(0%). Furthermore, the extrapyramidal symptom observed in the prochlorperazine group was akathisia, which occurred within a week. The results of this study suggest that careful attention should be paid so as not to overlook akathisia when using prochlorperazine as an antiemetic in cancer patients and that atypical antipsychotics, such as perospirone, could be used as alternatives.
