In a double-blind clinical trial with 20 patients suffering from endogenous depression statistically significant changes (improvement) were present in the scores of all assessment instruments. Although no statistically significant differences occurred between the groups, significant improvement on the HAM-D occurred earlier for amitriptyline and significant improvement occurred earlier on HAM-A for viloxazine. 2 patients were discontinued due to adverse reactions; one for nausea and vomiting while receiving viloxazine and one for paroxysmal atrial tachycardia while receiving amitriptyline. The same number of TES occurred for each group with seven unique to viloxazine (numbness, tingling, palpitation, ejaculation difficulty, nausea/vomiting, diarrhea, epigastric pain and gustatory disturbances) and seven unique to amitriptyline (insomnia, irritability, syncope, tremor, nasal congestion, orthostatic hypertension and paroxysmal atrial tachycardia). Other than for 1 patient who developed syncope and orthostatic hypotension and the patient who developed paroxysmal atrial tachycardia, there were no clinically significant changes in pulse rate, blood pressure and weight. There were no clinical laboratory findings with either drug that were judged to be pathological.

We examined the discriminant ability and responsiveness of the General Well-Being Adjustment Scale in patients enrolled in a randomized clinical trial of antihypertensive therapy. We also tried to translate the effects of physical symptoms on general well-being. This secondary analysis used demographic, clinical, physical symptom, and general well-being data for 545 white, male hypertensive patients. General well-being was measured by the General Well-Being Adjustment Scale (GWB) collected on 2 occasions over 8 weeks of treatment. Patients with any one of 14 physical symptoms or problems, compared to those without symptoms, had lower GWB scores (p < 0.003 to p < 0.0001). Decreases of 2.83-8.76 points in GWB scores were observed in patients developing physical symptoms over the 8 week study period (p < 0.05 to p < 0.0001). These effects were demonstrated in patients developing cold sensitivity, sexual problems, chest pain, shortness of breath, loss of taste, nausea, hot or cold spells, numbness and tingling, dry mouth, blurred vision, and dizziness. We conclude that the GWB is responsive to clinically meaningful changes in symptoms and may provide a more complete evaluation of the effects of medical treatment. The GWB is a valid and responsive measure of health status outcomes in the evaluation of antihypertensive treatment.

A 32-year-old man developed a rash on his body and extremities following acute fever of a few days duration, and also noticed pain and spontaneous tingling sensations in his lower extremities. Because severe pneumonia with dyspnea and low arterial blood oxygen concentration were found on examination, he was admitted and treated. After recovering from pneumonia in two months, he complained of abdominal symptoms, such as constipation, nausea and vomiting, spontaneous tingling sensations in the lower extremities, and orthostatic dizziness and fainting. On neurological examination, a mild to moderate muscle weakness was found in the distal muscles of both extremities. The ankle jerk was absent. Both superficial and deep sensations were moderately to severely decreased in the feet with positive Romberg's sign. Constipation and vomiting with nausea were noted. Clinical and laboratory examinations revealed marked orthostatic hypotension and hypohidrosis. Motor and sensory conduction studies indicated the presence of axonal degeneration and segmental demyelination and remyelination in the limbs nerves. CSF examination indicated that protein was 150 mg/dl and the cell count to be 18/mm3. Titer of antibody to rubella virus was significantly elevated. There were no other abnormalities to indicate the cause of motor, sensory and autonomic neuropathies. Therefore, the diagnosis of acute polyradiculoneuropathy with autonomic disturbances after rubella infection, which is rare in the literature, was made.

The estuarine dinoflagellate Pfiesteria piscicida gen. et sp. nov. produces exotoxin(s) that can be absorbed from water or fine aerosols. Culture filtrate (0.22 microns porosity filters, > 250 toxic flagellated cells/ml) induces formation of open ulcerative sores, hemorrhaging, and death of finfish and shellfish. Human exposure to aerosols from ichthyotoxic cultures (> or = 2000 cells/ml) has been associated with narcosis, respiratory distress with asthma-like symptoms, severe stomach cramping, nausea, vomiting, and eye irritation with reddening and blurred vision (hours to days); autonomic nervous system dysfunction [localized sweating, erratic heart beat (weeks)]; central nervous system dysfunction [sudden rages and personality change (hours to days), and reversible cognitive impairment and short-term memory loss (weeks)]; and chronic effects including asthma-like symptoms, exercise fatigue, and sensory symptoms (tingling or numbness in lips, hands, and feet; months to years). Elevated hepatic enzyme levels and high phosphorus excretion in one human exposure suggested hepatic and renal dysfunction (weeks); easy infection and low counts of several T-cell types may indicate immune system suppression (months to years). Pfiesteria piscicida is euryhaline and eurythermal, and in bioassays a nontoxic flagellated stage has increased under P enrichment (> or = 100 micrograms SRP/L), suggesting a stimulatory role of nutrients. Pfiesteria-like dinoflagellates have been tracked to fish kill sites in eutrophic estuaries from Delaware Bay through the Gulf Coast. Our data point to a critical need to characterize their chronic effects on human health as well as fish recruitment, disease resistance, and survival.

1. Despite advances in the art and science of fluid balance, exertional heat illness -- even life-threatening heat stroke -- remains a threat for some athletes today. 2. Risk factors for heat illness include: being unacclimatized, unfit, or hypohydrated; certain illnesses or drugs; not drinking in long events; and a fast finishing pace. 3. Heat cramps typically occur in conditioned athletes who compete for hours in the sun. They can be prevented by increasing dietary salt and staying hydrated. 4. Early diagnosis of heat exhaustion can be vital. Early warning signs include: flushed face, hyperventilation, headache, dizziness, nausea, tingling arms, piloerection, chilliness, incoordination, and confusion. 5. Pitfalls in the diagnosis of heat illness include: confusion preventing self-diagnosis; the lack of trained spotters; rectal temperature not taken promptly; the problem of "seek not, find not;" and the mimicry of heat illness. 6. Heat stroke is a medical emergency. Mainstays of therapy include: emergency on-site cooling; intravenous fluids; treating hypoglycemia as needed; intravenous diazepam for seizures or severe cramping or shivering; and hospitalizing if response is slow or atypical. 7. The best treatment is prevention. Tips to avoiding heat illness include: rely not on thirst; drink on schedule; favor sports drinks; monitor weight; watch urine; shun caffeine and alcohol; key on meals for fluids and salt; stay cool when you can; and know the early warning signs of heat illness.

The flight crews of aircraft often report symptoms including dizziness, nausea, disorientation, blurred vision and tingling in legs and arms. Many of these incidents have been traced to contamination of cabin air with lubricating oil, as well as hydraulic fluid, constituents. Considering that these air contaminants are often subjected to temperatures in excess of 500 degrees C, a large number of different exposures can be expected. Although the reported symptoms are most consistent with exposures to volatile organic compounds, carbon monoxide, and the organophosphate constituents in these oils and fluids, the involvement of these agents has not been clearly demonstrated. Possible exposure to toxic elements, such as lead, mercury, thallium and others, have not been ruled out. In order to assess the potential of exposure to toxic elements a multi-elemental analysis was done on two hydraulic fluids and three lubricating oils which have been implicated in a number of air quality incidents. A secondary objective was to establish if the multi-elemental concentrations of the fluids tested are different enough to allow such an analysis to be used as a possible method of identifying the source of exposure that might have been present during aircraft air quality incidents. No significant concentrations of toxic elements were identified in any of the oils or hydraulic fluids. The elemental compositions of the samples were different enough to be used for identification purposes and the measurement of only three elements was able to achieve this. Whether these findings have an application, in aircraft air quality incident investigations, needs to be established with further studies.

As part of a safety and tolerability study, a 65-year-old man with Parkinson's disease (PD) received monthly intracerebroventricular injections of glial-derived neurotrophic factor (GDNF). His parkinsonism continued to worsen following intracerebroventricular GDNF treatment. Side effects included nausea, loss of appetite, tingling, L'hermitte's sign, intermittent hallucinations, depression, and inappropriate sexual conduct. There was no evidence of significant regeneration of nigrostriatal neurons or intraparenchymal diffusion of the intracerebroventricular GDNF to relevant brain regions. Alternative GDNF delivery systems should be explored.

The purpose of the study was to assess the safety, adverse effects and complications of the dobutamine stress echocardiography (ED). 582 patients without previous infarction were prospectively studied with ED. There were 196 female and 368 male, age varied from 27 to 74 years, mean 52. Dobutamine was given in stepwise increasing doses from 5 to 40 mcg/kg/min. Mean maximal dose achieved was 33 mcg/kg/min. Atropine was added in 253 (43%) cases. Significant coronary artery disease was present in 323 patients (53%). There were no death, no myocardial infarction or episodes of sustained ventricular tachycardia as a result of ED. The test was terminated when following conditions were revealed: target heart rate (28.9%), maximal established dose achieved (25.3%), left ventricular asynergy (19.6%), angina pectoris (10.8%), increase of systolic blood pressure above 220 mm Hg (2.6%), hypotension (7.6%), nonsustained ventricular tachycardia (1.7%). The most common non-cardiac side effects were skin tingling (19.8%), atypical chest pain(16.3%), palpitations (13.9%) and headache (7.9%). The most side effects were usually well tolerated, without the need for test cessation. The ED was terminated only in 4 (0.6%) patients because of non-cardiac side effects including nausea (0.3%) and headache (0.3%). We conclude that ED may be safely performed in routine clinical practice. Side effects were rare and usually minor. Most severe ischemic pain was relieved by test interruption and sublingual nitro-glycerine or short acting beta-blocker administration.

Incidents of smoke in aircraft cabins often result from jet engine oil and/or hydraulic fluid that leaks into ventilation air, which can be subjected to temperatures that exceed 500 degrees C. Exposed flight-crew members have reported symptoms, including dizziness, nausea, disorientation, blurred vision, and tingling in the legs and arms. In this study, the authors investigated pyrolysis products of one jet engine oil and two hydraulic fluids at 525 degrees C. Engine oil was an important source of carbon monoxide. Volatile agents and organophosphate constituents were released from all the agents tested; however, the neurotoxin trimethyl propane phosphate was not found. The authors hypothesized that localized condensation of pyrolysis products in ventilation ducts, followed by mobilization when cabin heat demand was high, accounted for mid-flight incidents. The authors recommended that carbon monoxide data be logged continuously to capture levels during future incidents.

Dosage guidelines and side effects of three currently available protease inhibitors (saquinavir, ritonavir, indinavir) reveal very different patterns. Dosage regimens are as follows: saquinavir, 3 capsules every 8 hours with food; ritonavir, 6 capsules every 12 hours with food; and indinavir, 2 capsules every 8 hours on an empty stomach. Ritonavir has the severest side effects, including nausea, diarrhea, and initially, tingling feeling of the mouth, arms, or legs. The drugs work best when taken with well-studied medicines such as AZT, d4T, and ddI.
