Accidental acute mercury vapor poisoning in three persons is reported. Three hours after exposure, symptomatology began by chills, vomiting, diarrhea and chest pain. Two patients, respectively 67 and 77 year old, presented severe pulmonary edema, then neurological symptoms with tremor and coma. This toxic pulmonary edema, which entailed artificial ventilation, was followed in both cases by an acute interstitial pulmonary fibrosis which led to death respectively after six and sixteen days. In the third case (a thirty eight year old patient) a skin rash, erythematous and pustuliform was observed. Analysis for total mercury by flameless atomic absorption showed very high mercury levels in blood and urine of the three patients. The effect of treatment by Dimercaptopropanol on renal excretion of mercury was studied. Optic and electron microscopy of the lung of the two patients who died showed the pulmonary changes of acute interstitial fibrosis.

For phenomenological elucidation of panic attacks, 26 patients with panic attacks were requested to name the panic symptoms in order of their occurrence and specify the patterns of their abatement. Panic symptoms were found to be classifiable into three categories: early symptoms consisting of dizziness or faintness, palpitations, and sweating; intermediate symptoms dyspnea, nausea or abdominal distress, flush or chills, chest pain or discomfort, shaking, and choking; late symptoms paresthesias, fear of dying, and fear of going crazy. Panic symptoms disappeared in 61.6% irrespective of the sequence of their occurrence. Twenty-one patients were interviewed about the experience of nocturnal panic attacks, and 23.8% experienced them. These findings suggest that fear is caused by sudden physical abnormality triggered by some biological factors.

Persons with Q fever usually present with severe retrobulbar headache, a fever to 104 degrees F or higher with shaking chills, general malaise, myalgia, chest pain, and sometimes pneumonia and hepatitis. Cattle, sheep, goats, and ticks are the primary reservoirs of the etiologic agent, Coxiella burnetii. Humans are usually infected by inhaling infectious aerosols. Because C. burnetii can survive for long periods in the environment, it poses a continuing health hazard once it is disseminated. Q fever usually occurs sporadically, but large outbreaks are frequently observed throughout the world, particularly among abattoir workers and personnel working in research centers. Q fever endocarditis follows a chronic course and is frequently fatal. Tests for antibodies to C. burnetii are required for confirmation of the diagnosis. Tetracyclines remain the mainstay of treatment for acute Q fever, and tetracyclines in combination with other antibiotics have been advocated for patients with Q fever endocarditis. Vaccines for Q fever have been proven effective in clinical trials.

Dopexamine, a new compound with postjunctional dopamine receptor activating and beta adrenoceptor agonist properties, was given to 10 patients with chronic heart failure at diagnostic cardiac catheterisation to investigate its acute haemodynamic and metabolic effects. The drug was administered by intravenous infusion in three incremental doses and produced significant dose related increases in cardiac index, stroke volume index, and heart rate and falls in systemic vascular resistance and left ventricular end diastolic pressure; aortic and pulmonary artery pressures were unchanged. Isovolumic phase (max dP/dt and KVmax) and ejection phase (peak aortic blood velocity, maximum acceleration of blood, and maximum rate of change of power with time during ejection) indices of myocardial contractility were all increased by dopexamine but these changes were hard to interpret in the presence of an increase in heart rate. Myocardial efficiency and ejection fraction were both increased and left ventricular end diastolic and end systolic volumes fell. These largely beneficial changes were achieved without a statistically significant increase in myocardial oxygen consumption or disturbance of myocardial metabolic function. Dopexamine was well tolerated but tremor was reported by two patients at the intermediate dose and mild chest pain by two patients at the high dose.

Thirty-four patients were submitted to the conventional cervical myelography by administration of metrizamide (Amipaque) through three routes (lumbar 23, suboccipital 6, C1-C2 lateral 5). After the injection of metrizamide (4-11 ml, 170-250 mgI/ml), all procedures of the cervical myelography were done as soon as possible within 9 minutes. The adverse reactions of Amipaque were observed in 29 cases (85%) out of 34 cases initially 1 hour after cervical myelography and disappeared completely in an average of 16 hours. The total number of the side effects was 140 incidences such as meningeal irritation (headache 18, nausea 17, vomiting 17), cerebellar signs (dizziness 11, dysarthria 8, tremor 5, bradylalia 2, dysmetria 2, tipsy feeling 2, dysdiadochokinesis 1), autonomic signs (flushing 7, pale face 4, fever 4, sweating 2, hiccup 2, fatigability 2, micturition disturbance 1), sensory signs (exacerbation of numbness 6, perioral numbness 3, back pain 1, chest pain 1), motor signs (focal muscle spasm 5, exacerbation of paresis 4, areflexia 1), psychiatric signs (dysphasia 3, disturbance of consciousness 2, euphoria 1, persecutory delusion 1) and muddiness 7. We observed that waxing and waning of side effects correlated tightly with transient cortical penetration of dye in CT and cortical dysfunction mainly slowing of the background activity and slow wave burst in EEG. According to high frequency of side effects in our study, we suggest that a greater incidence of side effects may result when high concentration of Amipaque comes in contact with the cerebral cortex by using an inadequate fluoroscopic table which has only fixed one plane image and rough positioning control. Slow absorption into blood stream may affect appearance and maintenance of side effects. In order to decrease side effects after Amipaque cervical myelography, we propose that we should introduce a mobile rotating chair coupled with high power image and chose C1-C2 lateral route using 1500-1700mgI of Amipaque.

Panic disorder is a chronic illness that affects at least 3 percent of the population. Panic disorder is associated with significant morbidity and an increased risk of suicide. Patients generally present with multiple somatic and psychologic complaints, including heart palpitations, chest pain, tremor, shortness of breath, choking, nausea or abdominal distress, dizziness, derealization, fear of losing control or going crazy, fear of dying, paresthesias, chills or hot flushes, headache, diarrhea, insomnia, chronic fatigue, anxiety and depression. To make the correct diagnosis, these symptoms must be evaluated carefully since they also occur with serious cardiovascular, pulmonary, endocrinologic and neurologic disorders. Many effective treatments are available, including tricyclic antidepressants, selective serotonin reuptake inhibitors, monoamine oxidase inhibitors, benzodiazepines such as alprazolam and clonazepam, and psychotherapy.

Thalamic structures involved in the unpleasant emotional or affective aspect of pain are poorly understood. We now describe studies of the region of the thalamic principal somatosensory nucleus (Vc) performed before thalamotomy for tremor in a patient who also had panic disorder. Microstimulation in the region posterior to Vc evoked chest pain, including a strong affective dimension, almost identical to that occurring during his panic attacks, as measured using a questionnaire. Results in our other patients indicate that stimulation-associated pain with a strong affective dimension occurred only in those patients who had previously experienced spontaneous pain with a strong affective component. These results are consistent with stimulation-evoked activation of limbic structures, which are connected through cortex with the region posterior to Vc and involved in the affective dimension of pain through conditioning by previous experience.

Using cluster analysis of 207 patients with panic disorder (PD), we investigated the relationships between several panic symptoms at the time of panic attacks, which included anticipatory anxiety, agoraphobia, and 13 clinical symptoms based on the Diagnostic and Statistics Manual-III-Revised. Cluster analysis revealed three panic symptom clusters: cluster A (dyspnea, choking, sweating, nausea, flushes/chills); cluster B (dizziness, palpitations, trembling or shaking, depersonalization, agoraphobia, and anticipatory anxiety); and cluster C (fear of dying, fear of going crazy, paresthesias, and chest pain or discomfort). Generally, cluster A was comprised exclusively of physiological symptoms, among which respiratory symptoms were prominent, cluster B included both panic and non-panic symptoms such as agoraphobia and anticipatory anxiety, and cluster C was comprised chiefly of fear symptoms.

During December 1993-September 1995, the Bureau of Food and Drug Safety, Texas Department of Health (TDH), received approximately 500 reports of adverse events in persons who consumed dietary supplement products containing ephedrine and associated alkaloids (pseudoephedrine, norephedrine, and N-methyl ephedrine). This total included reports by individuals and reports identified by the Bureau of Epidemiology, TDH, in a review of records from the six centers of the Texas Poison Center Network. Reported adverse events ranged in severity from tremor and headache to death in eight ephedrine users and included reports of stroke, myocardial infarction, chest pain, seizures, insomnia, nausea and vomiting, fatigue, and dizziness. Seven of the eight reported fatalities were attributed to myocardial infarction or cerebrovascular accident. This report describes three patients in which the recommended dosage for the dietary supplements reportedly was not exceeded, summarizes results from ongoing investigations, and underscores the potential health risks associated with the use of products containing ephedrine.
