Common symptoms account for substantial patient disability and health services utilization. To determine the prevalence of 15 symptoms and the adequacy of therapy, 500 medical outpatients were surveyed. The 410 respondents indicated which symptoms were "major problems" and what therapy, if any, had been helpful. Each symptom was present in at least 10% of patients, with the most prevalent symptoms being fatigue (33%) and back pain (32%). Patients were clustered into three groups: (1) 140 were asymptomatic or monosymptomatic, (2) 135 reported 2 or 3 symptoms, and (3) 135 had 4 or more symptoms. The majority (77%) of these symptoms had been previously reported to a physician. Whereas 80% of patients with pain syndromes and gastrointestinal complaints had obtained some therapeutic benefit, only 39% of the individuals with fatigue, dyspnea, dizziness, insomnia, sexual dysfunction, depression, and anxiety reported any relief. Better therapy is needed for these common outpatient complaints.

We studied the effect of nalbuphine on the ventilatory and occlusion pressure responses to carbon dioxide rebreathing in six healthy male volunteers (mean age 25.5 yr) in a single-blind laboratory study. On four separate days volunteers were assigned randomly to receive either placebo (0.9% sodium chloride) or three i.v. doses of nalbuphine (15, 30 and 60 mg 70 kg-1), followed 90 min later by naloxone 0.4 mg 70 kg-1. Duplicate rebreathing tests were performed and the mean intercept at PE'CO2 7 kPa and the slopes of the linear relationship between inspiratory minute ventilation (Vl) or occlusion pressure (P0.1) with PE'CO2 were measured. Nalbuphine significantly decreased the mean intercept of the Vl (P less than 0.01) and P0.1 (P less than 0.05) responses, but caused no changes in the slopes. No significant difference between the doses was noted, suggesting that an Effect maximum (E'max) for respiratory depression was reached with a dose of approximately 15 mg 70 kg-1. Naloxone was less effective in antagonizing the depression in Vl at the higher dose of nalbuphine. Similar P0.1 values were associated with the same inspiratory flow rate (1 litre s-1) before and after drug treatment, suggesting that nalbuphine acts centrally to depress ventilation. Sedation increased significantly following each dose of nalbuphine (P less than 0.001). No demonstrable difference between the doses was shown, suggesting an Effect maximum (E'max) for sedation was reached at about 15 mg 70 kg-1. Administration of nalbuphine was associated with pain at the injection site, dizziness, dreaming, nausea and vomiting. Cardiovascular stability was maintained in all subjects.

The effect of gamma-hydroxybutyric acid (GHB) on ethanol withdrawal syndrome in alcoholics was investigated in a randomised double-blind study. Patients with withdrawal symptoms were treated either with GHB (orally in a syrup preparation) (11 patients) or with the syrup alone (12). GHB treatment (50 mg/kg) led to a prompt reduction in withdrawal symptoms, such as tremors, sweating, nausea, depression, anxiety, and restlessness. The only side-effect was dizziness. GHB may be useful in the management of alcohol withdrawal syndrome in man.

Flunarizine hydrochloride (FZ), a calcium entry blockade, has been used nationwide in Japan as a cerebral active vasodilator since October, 1984. The present paper reports 31 cases of FZ-induced Parkinsonism, depression and akathisia, referred to our hospital between October 1986 and September 1988. Out of the 31 patients, four including two with Parkinson's disease and one each with progressive supranuclear palsy and olivopontocerebellar atrophy showed worsening of their parkinsonian symptoms within a few months after FZ administration. The remaining 27 patients (7 males and 20 females) newly developed Parkinsonism after treatment with FZ. Symptoms appeared one week to two years (mean: 6.1 months) after starting FZ of a daily dose of 10 mg. FZ had been used in 6 patients for cerebrovascular episodes confirmed by clinical history or brain CT, and in the remainder, for dizziness, light-headedness, hypertension, amnesia or hypochondric neurotic complaints. Akinesia and bradykinesia progressed rather rapidly after onset, and patients became unambulatory within several months. Symptoms had worsened, and L-dopa, anticholinergic drugs, and bromocriptine had been ineffective until FZ was discontinued. Their Parkinsonism was characterized by marked akinesia, bradykinesia, and moderate rigidity. Masked face was seen in most of them. Tremor was absent at rest, and induced in 12 patients by posture and/or action. Sixteen patients were accompanied by depression, and five, by akathisia. Improvement began several weeks after withdrawal of FZ, and most patients recovered almost completely within a few months although mild rigidity and bradykinesia remained in some.(ABSTRACT TRUNCATED AT 250 WORDS)

Epidural analgesia is an important intervention in patients with pain after surgery. This article presents a brief overview of the anatomy of the epidural space and the physiology of pain transmission, including the action of narcotics in pain relief. The importance of written nursing protocols and in-service education for nursing staff members is discussed as being a necessary prerequisite for the safe use of epidural analgesia. A flow diagram with rationale illustrates the epidural injection technique. Nursing care of patients receiving epidural narcotics is detailed. The discussion emphasizes the management of potential side effects from epidural narcotics (respiratory depression, urinary retention, pruritus, pain on injection, dizziness, nausea, and vomiting) and includes information on the use of a narcotic antagonist. Recommendations are made for preoperative and postoperative teaching of the patient and family. A variety of tools for assessing patients' pain levels are described, and a comprehensive nursing care plan with nursing diagnoses and nursing interventions is provided.

A randomized, prospective, comparative study was performed to evaluate induction characteristics, haemodynamic changes and recovery in 60 ASA I-II patients undergoing mainly gynaecological laparotomies with either propofol or thiopentone-enflurane anaesthesia. The propofol group (n = 30) received 2 mg.kg-1 propofol for induction of anaesthesia followed by propofol infusion. The thiopentone-enflurane group (n = 30) received thiopentone 4 mg.kg-1 for induction followed by enflurane (0.5-2 per cent). All patients received nitrous oxide (66 per cent] in oxygen begun one minute after tracheal intubation, and fentanyl (1.5 micrograms.kg-1) four minutes prior to induction. Other drugs administered during or after anaesthesia were similar among the groups. Haemodynamic measurements were similar between propofol and enflurane groups except after tracheal intubation when the mean arterial pressure was lower in the propofol group (P less than 0.05). The propofol group had significantly less (P less than 0.01) emesis in the recovery room than the enflurane group. The propofol group experienced significantly less (P less than 0.05) dizziness, depression/sadness and hunger than the enflurane group in the postoperative period as assessed with a visual analogue questionnaire. We conclude that propofol provided better outcome than enflurane in terms of these nonvital but annoying outcome measures after relatively long intra-abdominal operations.

Regional cerebral blood flow (CBF), mood states and somatic symptoms were measured before and after inhalation of amyl nitrite in 10 physically healthy volunteers with a prior history of using volatile nitrites for recreational purposes. CBF was measured with the same technique, under identical laboratory conditions, in an equal number of normal volunteers. During CBF measurements, blood pressure, pulse rate, respiratory rate and end-tidal levels of carbon dioxide were monitored. The amyl nitrite group and the control group were compared on CBF, rating scale scores and physiological indices via analysis of variance. Amyl nitrite inhalation was associated with significant global increases in CBF, while the control group did not show any change. Pulse rate increase was the only physiological change associated with administration of the drug. Subjects who received the drug reported significant decrease in anger, fatigue and depression and increased palpitation, breathing difficulty, dizziness and headache. Changes in the rating scale scores, physiological indices, and somatic symptoms after amyl nitrite did not correlate with regional CBF change.

A Caucasian male contracted acquired immune deficiency syndrome (AIDS) following a blood transfusion during heart surgery. Four years later he developed dizziness, dysequilibrium, and emotional disturbances. Neurotologic evaluation implicated central vestibular and auditory dysfunction. Electronystagmographic findings showed ataxic pursuit and optokinetic nystagmus, with a total loss of caloric excitability. The auditory brain stem response indicated delayed absolute and interpeak latencies, and the synthetic sentence identification test yielded abnormally reduced scores bilaterally. Psychological tests suggested organic brain disease with severe anxiety and depression. At autopsy, the AIDS retrovirus was found in mononuclear and multinucleated giant cells in the cortical and subcortical gray matter, cerebral and cerebellar white matter, and throughout the brain stem. Pathologic changes were consistent with the patient's neurotologic profile.

Dizziness was studied in 1,622 community-dwelling adults aged 60 and older who were interviewed as part of the Duke Epidemiologic Catchment Area study. The lifetime prevalence of dizziness (defined as severe enough to see a physician, to take a medication, or to interfere with daily activities) was 29.3%; the 1-year prevalence was 18.2%. When the subgroup with dizziness was compared with those who never suffered dizziness, using logistic regression, four variables displayed the strongest associations: a constructed variable of risk for multiple neurosensory deficits, a cardiovascular risk score, a depression symptom inventory, and perception of self as a nervous person. In this population, dizziness was not associated with increased risk of death or institutionalization at the 1-year follow up.

A 15-year-old boy with diarrhea, dizziness, dysesthesias, and depression is described. On admission, his blood pressure was 110/84 reclining but less than 40 systolic while standing. Vibratory sensation and nerve conduction velocities were decreased in his lower extremities. CSF protein concentration was normal but sural nerve biopsy demonstrated generalized demyelination. Extensive toxicologic and metabolic screening proved unremarkable. Norepinephrine concentrations in plasma and urine, and CSF concentration of 3-methoxy-4-hydroxy phenylglycol (MHPG) were markedly reduced. The patient demonstrates a combination of autonomic dysfunction, peripheral neuropathy, and affective disorder. This collection of clinical and neurochemical findings represents a previously unreported entity involving a defect of both central and peripheral noradrenergic systems.
