Dental personnel are exposed to low concentrations of mercury vapor in their working environment and from their own amalgam fillings. This study included 505 occupationally exposed individuals working at 82 dental clinics in northern Sweden and 41 controls without occupational mercury exposure. The concentration of mercury in air was measured. Urine mercury was determined for all participants, who also answered a questionnaire focused on four symptoms known from the literature to be connected with mercury exposure, namely loss of appetite, tremor, insomnia and anxiety. The median value of mercury vapor in air in the dental surgeries was low compared with other investigations; 1.5 micrograms m-3 in public dental care and 3.6 micrograms m-3 in private dental care. The urine mercury concentrations (HgU) were low, and of the same order of magnitude as for the Swedish population as a whole. Median values among different groups of dental personnel ranged from 1.4 to 2.9 nmol Hg/mmol creatinine. For those occupationally exposed, the load from their own amalgam fillings was estimated to be of the same order of magnitude as from the working environment. The prevalence of any of the four symptoms investigated in the groups of exposed personnel and controls as low, less than or equal to 11%. In our study, which included mercury intakes up to twice the contribution from amalgam fillings, no increase in the prevalence of symptoms could be detected in relation to mercury concentrations in urine.

The care given to 26 dying patients, and their families, being nursed in a hospital where there was no specific terminal care facility was studied. These patients were dying from both malignant and non-malignant disease. Anorexia, sleeplessness, coated or infected mouths, pain, and pressure sores were seen in half of the patients. Fear about caring for the patient at home and lack of information were the problems most frequently identified by the relatives. As a result of this study a multidisciplinary team specialising in symptom control and supportive care has been established. On average half of the total number of patients dying from cancer in the hospital are supported by the team. The number of complaints from relatives of dying patients has been drastically reduced since the team was formed.

A multicenter, randomized, double-blind, comparative study was conducted in 274 patients with mild to moderate hypertension to assess the impact of nitrendipine and propranolol on quality of life. After placebo baseline, 136 patients were given nitrendipine (5-20 mg b.i.d.) and 138 were given propranolol (40-120 mg b.i.d.). Quality of life was evaluated at baseline, weeks 6-10, and weeks 14-18 of the maintenance period. At weeks 6-10, the nitrendipine group became significantly more vigorous (p less than 0.01) and less fatigued (p less than 0.05) than the propranolol group. Propranolol subjects noted decreased problems of trembling hands (p less than 0.01) and alcohol use (p less than 0.05) than the nitrendipine subjects. No other significant differences between groups in mood states, troublesome conditions (insomnia, headaches, and loss of appetite), or sexual satisfaction were noted at this visit, and patient willingness to continue study medication was marginally significantly higher (p less than 0.1) in the nitrendipine group than in the propranolol group. At weeks 14-18, the propranolol subjects perceived significantly decreased problems with the "felt worried, tense, and drank alcohol to cope" factor (p less than 0.05); however, there were no differences between groups at this visit for Profile of Mood States (POMS) scores, sex life variables, or medication preference. Based on within-group analysis, the propranolol group perceived a reduction in partner sexual satisfaction (p less than 0.05). Overall, nitrendipine seemed to be better tolerated than propranolol.

A yin-yang hypothesis is presented linking noradrenergic activity, thromboxane, melatonin, left hemisphere functioning, and cyclic AMP on the one hand, and dopamine, beta-endorphin, calcium, right hemisphere functioning, and cyclic GMP on the other. It is further suggested that there is a yoking of NA, TXA2, serotonin and melatonin in the left hemisphere, and a similar yoking of DA, BE, calcium and cGMP in the right. Evidence is presented to support the hypothesis that each element (NA, TXA2, etc.) on one side can modulate or balance a corresponding element (DA, BE, etc.) on the other. It is suggested that thromboxane is the key element in noradrenergic overactivity and that not taking this into consideration has confounded much prior research. This theory takes into account information processing models as well as pharmacological data and neurochemical theory on coupling of adenylate cyclase to its hormone receptors. Inhibiting noradrenergic overactivity can be obtained by inhibiting thromboxane and concomitantly activating opiate receptors. This protocol may have clinical utility in treating a wide range of disorders such as: anxiety, depression, schizophrenia, sleeplessness, withdrawal states, enuresis, Gilles de la Tourette syndrome, Parkinsonism, Alzheimers, dementia, anorexia, infant ruminations, essential tremor, spasticity of spinal cord injury, diarrhoea, ulcerative colitis, extrapyramidal symptoms, akathisia, neuroleptic malignant syndrome, attention deficit disorder, hyperhidrosis, and possibly AIDS.

A case of psychosis occurring 13 days after 1st trimester abortion in a 17-year old primigravida without family history of mental illness of postpartum psychosis is described. The young woman denied any ambivalence or guilt concerning abortion. The abortion itself involved repeat hospitalization for evacuation of retained products, and a course of antibiotics (metronidazole). The illness was marked by insomnia, anorexia, labile mood, auditory hallucinations, inappropriate speech, flat affect, and withdrawal alternating with disinhibition. She was hospitalized 10 days after onset, and treated with neuroleptics (pimozide 4 mg/day). She improved rapidly, and was discharged, taking medication for a few more weeks. After stopping medication she became pregnant, and delivered without any further psychotic symptoms. It is unlikely that metronidazole caused the illness, although it has been associated with confusion, disorientation and hallucinations, because the symptoms occurred 2 days after discontinuing the drug. On the other hand, the patient's flat affect after recovery suggests she might have had incipient schizophrenia.

This is a report of the clinical analysis of 250 cases of dengue fever-like patients during the 1987-1988 epidemic in Southern Taiwan at Harn's clinic, Kaohsiung city. The results were: The peak age groups were between 20-40 years old. The ratio of male to female was 1:14. 98% patients presented with fever of mainly 3 to 6 days duration. 98% reported body pain, which included headache (82%), generalized soreness (65%), low back pain (50%). 95% patients had GI symptoms, such as anorexia (73%), nausea (60%), vomiting (45%). 97% patients complained of dizziness and weakness, and 22.4% patients had a bleeding tendency. The common bleeding sites were involving the subcutaneous (skin), gum, uterus, nasal cavity, GI tract, retina, and GU tract. The eruption rate was 78%. A majority of rashes appeared on the extremities, and then spread to the trunk. Less common symptoms were insomnia, chest tightness, urgency of urination, cough, running nose, palpitation, and shock. 45% patients were noted with hair loss. The hair loss was the latest presenting symptom, which tended to occur about two months after the recovery stage, and lasted for about one month. On physical examination, 62.6% patients had conjunctivitis, while only 1.3% had lymph node enlargement. Usually, the whole clinical course lasted for 7 to 14 days. Laboratory examination showed that leukopenia was noted from the second day and reached the lowest count on the fifth day, and recovered on 9th or 10th day. In 247 blood sera tested serologically for dengue fever, 84 were confirmed, while 157 were not confirmed yet due to patients' reluctance to accept a second blood drawing.(ABSTRACT TRUNCATED AT 250 WORDS)

The authors review the literature discribing non-dyskinetic antipsychotic withdrawal phenomena. Withdrawal of these agents can cause nausea, emesis, anorexia, diarrhea, rhinorrhea, diaphoresis, myalgia, paresthesia, anxiety, agitation, restlessness, and insomnia. Psychotic relapse is often presaged by increased anxiety, agitation, restlessness and insomnia, but the temporal relationship of these prodromal symptoms to reduction in the dosage or discontinuation of neuroleptics distinguishes them from the effects of abrupt withdrawal.

The literature describing nondyskinetic antipsychotic withdrawal symptoms is reviewed. The withdrawal of antipsychotic agents can result in nausea, emesis, anorexia, diarrhea, rhinorrhea, diaphoresis, myalgias, paresthesias, anxiety, agitation, restlessness, and insomnia. Psychotic relapse is often presaged by increased anxiety, agitation, restlessness, and insomnia. However, the temporal relationship of these prodromal symptoms to reduction in the dosage or discontinuation of neuroleptics distinguishes them from the effects of abrupt withdrawal.

The incidence of acute mountain sickness was determined by questionnaire in 454 individuals who attended week-long continuing medical education programs at ski resorts in the Rocky Mountains with base elevations of about 2000 m. As a control group, 96 individuals who attended continuing medical education programs at sea level in San Francisco completed similar questionnaires. Study subjects were classified as having acute mountain sickness when they reported three or more of the five possible cardinal symptoms: headache, insomnia, dyspnea, anorexia, and fatigue. Only symptoms with an intensity of at least grade 2 (moderate) out of 5 were analyzed. Acute mountain sickness-like symptoms occurred in 25% of subjects at 2000 m compared with 5% of subjects at sea level. The incidence of acute mountain sickness at 2000 m was greatest among subjects who had come from lower altitudes. Half of the subjects with symptoms took medication. The duration of symptoms was short, with 90% of all symptoms that were reported occurring in the first 72 hours. Acute mountain sickness is common at intermediate altitudes, and it is frequently severe enough to prompt self-medication.

To test the value of dexamethasone acetate for ameliorating acute mountain sickness (AMS), we conducted a double-blind, randomized study that compared the effects of 4 mg of dexamethasone acetate or a placebo (given every six hours for six doses beginning at the time of exposure) at 2700 and 2050 m. Study subjects, who were recruited from health professionals who attended continuing medical education programs at ski resorts in the Rocky Mountains, were classified as having AMS when they reported three or more of the five usual symptoms (headache, insomnia, dyspnea, anorexia, and/or fatigue) on a single day. All symptoms with an intensity of at least grade 2 (moderate) out of 5 were analyzed. At 2700 m, there was a 50% decrease in the mean AMS symptom score in the dexamethasone group (0.94 +/- 1.11 vs 1.84 +/- 1.44 [mean +/- SD]) and the incidence of AMS was 20% of that in the control group (3/38 vs 14/35). At 2050 m, there was no difference between dexamethasone and a placebo in the mean AMS symptom score (1.52 +/- 1.50 vs 1.24 +/- 1.33) and the incidence of AMS (5/25 vs 4/25). Dexamethasone ameliorates the usual symptoms of AMS at 2700 m but not at 2050 m.
