We report a 73-year-old right-handed female who presented with an acute amnesic syndrome. On November 18, 1991, she was admitted to a local hospital complaining of sudden-onset vertigo and nausea, but immediately after the admission she developed an amnesic syndrome. On November 27, she was transferred to our hospital for further assessment of her memory disturbance. Neurologically she was normal except for mild right hemianopsia and increased deep tendon reflexes in the extremities. Neuropsychological assessments were performed over 3 weeks. She was always alert, attentive, and cooperative. She had no confabulation. On the Wechsler Adult Intelligence Scale revised (WAIS-R), her total IQ was 110. Frontal, verbal, and perceptual functions and motor performance were normal. She had no signs of a callosal disconnection. Despite these preserved functions, her memory function was obviously disturbed. Several memory betteries showed that her recent memory for both verbal and visual modalities was impaired, while her immediate memory such as digit span was preserved. For remote memory her retrograde episodic memory concerning both personal and public events was almost intact, although she had a profound anterograde amnesia. In particular she recalled her personal information about just-premorbid events in detail. On the other hand, her semantic memory, for example understanding of proverbs, geography, and scientific law, was preserved. Taken together, her procedural memory on learning tasks, such as "Tower of Hanoi" and mirror drawing, was intact. Computed tomography demonstrated a low-density area medial to the trigon of the left ventricle.(ABSTRACT TRUNCATED AT 250 WORDS)

300 women aged 16-37 received analgesic-sedative preparations for miniabortions preprandially after admittance to the clinic. Anamnesis was followed by routine blood pressure check, then 0.01 mg/kg-1 atropine, 0.1 mg/kg-1 diazepam iv, or 0.05 mg/kg-1 midazolam iv was given to 25 women. 1-2 minutes later 0.5 mg/kg-1 ketamine iv was given, and at the time of insertion of the aspiration cannula into the cervix, another dose of 0.25 mg/kg-1 of ketamine was given iv. The total dose did not exceed 1 mg/kg-1 iv. All patients also received a ketamine-benzodiazepine combination of analgesia prior to the miniabortion procedure. In psychic, unstable women anxiolytic effects were apparent, but in all of them vertigo and the sensation of floating ensued with horizontal and vertical nystagmus, although information could be extracted from them depending on the degree of analgesia. Anterograde amnesia followed, and the systolic and diastolic pressure increased. The maximum duration of analgesic effect was 3-5 minutes, most women became well-oriented without ataxia and returned home 4 hours after the operation. No psychic effects lasted, and nausea or vomiting was minimal. The hallucinogenic effect of ketamine was attributable to the stimulation of the central dopaminergic system, while diazepam (Spofa) influenced the limbic system causing anterograde amnesia. The potential of midazolam-benzodiazepine combination for future sue lies in its very short biological half-life (1.5-2.5 hours) compared with diazepam (24-36 hours).

In a randomized, prospective, double-blind trial we investigated the efficacy and safety of the benzodiazepine antagonist RO 15-1788 in 57 patients undergoing general surgery. Anesthesia was induced and maintained by a combination of Flunitrazepam-Fentanyl-Pancuronium. Inhalation anesthetics were excluded from the study. After reversal of any residual relaxant effect we titrated RO 15-1788 or placebo by repeated i.v. administration of 0.1 mg (= 1.0 ml) up to a maximum dosage of 1.0 mg or to a definite arousal reaction. Before as well as 5, 10, 15, 30, 60, and 120 min after injection of the trial substance we evaluated efficacy (sedation, comprehension and collaboration, orientation in time and space), presence of anterograde amnesia, side-effects, hemodynamics, and subjective patient assessment by a point scale. RO 15-1788 significantly improved the level of consciousness (P less than 0.005) at a dosage of 0.59 +/- 0.29 mg at 5, 15, 30, and 60 min after administration as well as orientation in time and space (P less than 0.005) after 30 min. There was significantly less anterograde amnesia (P less than 0.005) after 15, 30, and 60 min. Symptoms of a benzodiazepine rebound effect after 120 min indicate a short half-life time of RO 15-1788. We did not observe any hemodynamic side effects. Local tolerance was good. Side effects in terms of nausea (1 case), vomiting (4), euphoria or dysphoria (2), benign cardiac arrhythmias (1) or a state of excitation (1) occurred several times after RO 15-1788 as well as after placebo (nausea 2, vomiting 6, muscular tremor 1). Our results indicate the efficacy and safety of RO 15-1788.

Forty female out-patients undergoing therapeutic abortion participated in a double-blind study comparing flunitrazepam 0.05 mg . kg-1 with thiopentone 6.0 mg . kg-1 as induction agents for general anaesthesia. Induction time, as measured by the time to loss of lid reflex and voluntary speech, was not only significantly longer in patients receiving flunitrazepam, but also much more variable and imprecise than with thiopentone. The Steward recovery room scores and psychomotor drawing test results revealed that recovery was significantly slower in the flunitrazepam group. Anterograde amnesia was observed in all patients who had received flunitrazepam and in one patient who had received thiopentone. No retrograde amnesia was found in either group. Flunitrazepam produced postoperative drowsiness, sedation, ataxia and nausea while with thiopentone discomfort from surgery and discomfort at the intravenous injection site were the main complaints. Because of the slowness of induction with flunitrazepam and marked individual variation, we do not feel that this drug can be considered a suitable agent for routine induction of general anaesthesia.

A 71-year-old woman with myelofibrosis on chemotherapy experienced an acute illness with nausea, vomiting, and diarrhea. Two weeks later, she developed an acute confusional state characterized by disorientation and fluctuating alertness with normal speech and language. Her neurologic examination demonstrated an upper motor neuron pattern of right hemiparesis. She reported double vision though ophthalmoparesis was not appreciated. Her gait was normal. While hospitalized, she developed generalized tonic-clonic seizures. Brain MRI revealed a small area of restricted diffusion of the left precentral gyrus (figure). She was diagnosed with a stroke with secondary seizures; however, as the confusional state resolved, she developed profound retrograde and anterograde amnesia. Review of the brain MRI showed high T2 signal in the medial thalamus and contrast enhancement of the mamillary bodies; a diagnosis of Wernicke-Korsakoff syndrome was entertained and she was started on thiamine replacement. The encephalopathy and hemiparesis resolved though she remains severely amnestic.
