We experienced a patient with panhypopituitarism which occurred following extensive brainstem and cerebellar infarction due to dissection of basilar artery (BAD). Panhypopituitarism followed by BAD has not yet been reported in the literature. The patient was a 67-years-old man who was admitted to our hospital because of a sudden onset of consciousness disturbance and vomiting. On the day of admission, he was drowsy and had left IIIrd nerve palsy, skew deviation, occular bobbing, and left hemiparesis. His neurological state was rapidly deteriorated, and fell almost into apneic state, requiring artificial ventilation for a week. Cerebral angiography demonstrated a double lumen sign of the basilar artery confirming the diagnosis of dissection. There were extensive hypodensities in the brainstem and bilateral cerebellar hemispheres on CT. On day 20, he suddenly became shocked following infection. Even after the effective and successful treatment of infection, severe hypotension continued that required administration of chatecholamine agents. Laboratory examinations revealed that he had panhypopituitarism. Supplement therapy with adrenocortical hormones made his circulatory state improved, and could finally be stopped on day 100. In the present case, subclinical hypopituitarism was considered to occur mainly from compression of the pituitary stalk and hypothalamus by the enlarged BAD. Increased intracranial pressure and upward herniation may also have made the pituitary function worse, and the infection finally triggered the adrenal crisis. The BAD occurs more frequently than previously considered, and should be kept in mind as a cause of secondary panhypopituitarism.

The purpose of this study was to determine the optimal schedule of i.v. granisetron and dexamethosone for control of nausea and emesis in patients receiving high-dose chemotherapy (HDC). Seventy patients with breast cancer received high-dose cyclophosphamide, thiotepa and carboplatin (CTCb) for 3 consecutive days. All 70 received dexamethasone 12 mg i.v. and granisetron 1 mg i.v. prior to infusion of CTCb and were randomized to receive placebo (n = 37) or an additional identical dose of granisetron (n = 33) 12 h later. Beginning on day 2 of chemotherapy administration, 55 patients evaluable later self-administered a cocktail of diphenhydramine (benadryl), lorazepam (ativan) and dexamethasone (BAD). Fourteen of 37 patients (38%) receiving granisetron once a day and 15/33 (44%) receiving it twice a day had a complete response during the first 24 h following the first doses of chemotherapy (P = 0.52). In the 55 evaluable patients receiving BAD, 18 of 29 (62%) in the once daily group and 14/26 (54%) in the twice daily group required additional medications (P = 0.54). The median time to first emetic episode was 20 h (range 6.6-79.5) for patients receiving once a day and 21.4 hours (range 5.8-105.3) for patients receiving twice a day granisetron (P = 0.48). Five patients in the once daily and seven patients in the twice daily group had complete control of nausea and emesis throughout the study period (P = 0.37). It was concluded that there were no statistically significant differences in nausea and emetic control between dexamethasone with once daily or twice daily i.v. granisetron administration in patients receiving high-dose CTCb.

We evaluated the combination of diphenhydramine, lorazepam, and dexamethasone delivered as a continuous i.v. infusion via an ambulatory infusion pump with patient-activated intermittent dosing (BAD pump) for prevention of acute and delayed nausea/vomiting in patients receiving high-dose chemotherapy (HDC) for peripheral blood progenitor cell (PBPC) mobilization (MOB) or prior to autologous PBPC rescue. The BAD pump was titrated to patient response and tolerance, and continued until the patient could tolerate oral anti-emetics. Forty-four patients utilized the BAD pump during 66 chemotherapy courses, 34 (52%) for MOB and 32 (48%) for HDC with autologous PBPC rescue. The median number of days on the BAD pump during MOB and HDC was 3 (1-6) and 9 (2-19) days, respectively. Complete overall or complete emesis control occurred on 94% of MOB and 89% of HDC treatment days during chemotherapy administration and 72% and 43%, respectively, following chemotherapy administration. Eighty-three percent of MOB and 55% of HDC treatment days were associated with no nausea. While on the BAD pump, no patient experienced severe toxicity or required hospitalization for management of nausea/vomiting. The BAD pump was safe and effective in minimizing nausea and vomiting associated with HDC, and thus, eliminated the need for hospitalization for management of chemotherapy-induced nausea and vomiting.

This study assessed the efficacy and safety of dolasetron compared with ondansetron for the prevention of nausea and vomiting during high-dose myeloablative chemotherapy followed by peripheral blood stem cell support. Twenty centers randomized 197 patients to receive dolasetron 100 mg intravenously (I.V.) followed 8-12 hours later by a single oral dose of dolasetron 100 mg or ondansetron 32 mg I.V., followed 8-12 hours later by a single oral dose of ondansetron 8 mg during high-dose chemotherapy (HDC) regimens for breast cancer (n = 96; 48.7%), non-Hodgkin's lymphoma (n = 83; 42.1%), or Hodgkin's disease (n = 18; 9.1%). All patients received a daily I.V. bolus of dexamethasone 10 mg with study antiemetic agents and a continuous infusion of diphenhydramine, lorazepam, and dexamethasone (ie, BAD pump) throughout the course of the study, with patient-controlled on-demand bolus doses as needed. After completing a daily diary of emetic episodes and rescue medication use, 164 of 197 patients were evaluable. Total plus complete responses (no emesis, no nausea, no rescue) over the entire study period were achieved in 45.7% and 46.9% of patients on the dolasetron and ondansetron arms, respectively. Dolasetron and ondansetron were well-tolerated. This study demonstrates that dolasetron and ondansetron are equally safe and effective in the prevention of nausea and vomiting associated with HDC (P = 0.955).
