80 strictly selected patients with chronic renal insufficiency with plasma creatinine values of 1.4--14.5 mg% were examined according to a fixed scheme to determine the presence of symptoms and signs of renal encephalopathy. The general cerebral symptoms complained of were headache in 33.4% of the patient material, dizziness in 30.3%, easy fatigability in 62.5%, giddiness in 18.8% and insomnia in 37.5%. The most prominent neurological findings were hyperactive deep reflexes in 30% and action tremor in 23.8%. The symptoms of organic brain syndrome were impairment of memory in 32.5%, weakness of concentration in 28.8% and lability of affect in 63.7%. Diffuse EEG abnormalities were found in 26.2%. While the clinical neuropsychiatric symptoms did not show any statistically significant correlation with the various internal medical data, a trend was observed in the greater number of pathological EEGs with an increase in the impairment of renal function. Furthermore, there was a statistically significant correlation, (alpha less than or equal to0.015) between the occurrence of pathological EEGs and the plasma creatinine and BUN values. It is remarkable that the patients with abnormal EEGs had a relatively low mean creatinine level of 5.89 mg%. The strict dietetic management of the patients is regarded as one of the deciding factors for the relatively low frequency of neuropsychiatric symptoms in the material studied.

A good tumoricidal activity of vindesine (VDS) has been reported in a variety of animal tumors and in human leukemias and lymphomas. We treated 22 patients who had received no prior chemotherapy and were suffering from a variety of malignant neoplasms with 0.5 mg/m2 to 3.0 mg/m2 VDS i. v. once or three times at weekly intervals and recorded the clinical, hematologic, and especially, neurological side effects. Clinically we observed fatigue in nine patients, paresthesias in seven, myalgias in three, vertigo and diarrhea in two, and skin pains, tinnitus, gastric pains, alopecia, and tremor in one patient each. There was no obvious dose-action relationship. Paravenous injection caused cellulitis similar to that seen with vincristine. No side effects were apparent in liver (SGPT) and renal (creatinine) function tests. Hematologically there was a clear trend toward leukopenia with higher doses of DVA and a mean increase in the thrombocyte count by 51 X 10(3)/mm3 was found (sign test: P greater than 0.05). The hemoglobin level did not change. Clinical neurological examination and monitoring by electroneurography revealed no changes in tensiometer performance, motor and sensory nerve conduction velocity, motor or sensory nerve action potential amplitudes, or H-reflex responses. There was dose-related diminution of the proprioceptive reflexes, especially in the lower extremities. Even with as little as 2.0 mg/m2 VDS i. v. at weekly intervals for 3 weeks Achilles and patellar tendon reflexes were diminished or absent in all patients.

42 episodes of verified or clinically suspected cytomegalovirus (CMV) infection in 40 bone marrow transplant (BMT) recipients were treated with foscarnet (trisodium phosphonophormate hexahydrate). CMV infection was verified in 31/42 treatment episodes. Symptoms treated were pneumonia (n = 17), pancytopenia with or without fever (n = 12), enteritis (n = 5), fever (n = 4), encephalitis (n = 2), retinitis (n = 1) and hepatitis (n = 1). Foscarnet was given as a continuous intravenous infusion. Side-effects observed were increase in serum creatinine (38%), decrease in serum calcium (19%), increase in serum bilirubin (12%), decrease in hemoglobin concentration (7%), increase in serum calcium (5%), increase in serum transaminase (5%), hypophosphatemia (2%) and tremor (2%). CMV was eradicated from blood and/or urine in 11/25 (44%) of assessable treatment episodes with infection verified by isolation. Overall clinical improvements including eradication of CMV, afebrility and/or improvements in laboratory abnormalities were seen in 14/31 (45%) episodes of verified infection. All 15 patients with CMV interstitial pneumonia (CMV IP) died. We conclude that foscarnet is nephrotoxic but otherwise well tolerated with moderate clinical and virostatic effects on CMV infection. The effect on CMV IP is discouraging.

Possible effects of mercury on the central nervous system (CNS) were examined in a group of chloralkali workers exposed to mercury (n = 89) and compared with a control group (n = 75), by registration of subjective symptoms, personality changes, forearm tremor, and performance on six computerised psychometric tests in the two groups. The groups were similar in age, education, verbal comprehension, and work tasks. In the chloralkali group, median blood mercury concentration (B-Hg) was 55 nmol/l, serum mercury concentration (S-Hg) 45 nmol/l, and urine mercury concentration (U-Hg) 14.3 nmol/mmol creatinine (25.4 micrograms/g creatinine). Corresponding concentrations in the control group were 15 nmol/l, 4 nmol/l, and 1.1 nmol/mmol creatinine (1.9 micrograms/g creatinine) respectively. The number of self reported symptoms, the scores for tiredness and confusion in the profile of mood states (POMS), and the degree of neuroticism in the Eysenck personality inventory (EPI), were significantly higher in the mercury exposed group compared with the controls. Performance on the psychometric tests and tremor frequency spectra did not differ significantly between the two groups. Dose-response calculations showed weak but statistically significant relations between symptom prevalence and current mercury concentrations in both blood and urine. The performance on three of the psychometric tests was negatively correlated with earlier peak exposures. The findings indicate a slight mercury induced effect on the CNS among the chloralkali workers.

The prevalence of neuropsychological and respiratory symptoms, lung ventilatory parameters, neurofunctional performances (visual reaction time, eye-hand coordination, hand steadiness, audioverbal short term memory), and several biological parameters (calcium, iron, luteinising hormone (LH), follicle stimulating hormone (FSH), and prolactin concentrations in serum, blood counts, manganese (Mn) concentration in blood and in urine) were examined in a group of workers (n = 92) exposed to MnO2 dust in a dry alkaline battery factory and a matched control group (n = 101). In the battery plant, the current exposure of the workers to airborne Mn was measured with personal samplers and amounted on average (geometric mean) to 215 and 948 micrograms Mn/m3 for respirable and total dust respectively. For each worker, the lifetime integrated exposure to respirable and total airborne Mn dust was also assessed. The geometric means of the Mn concentrations in blood (MnB) and in urine (MnU) were significantly higher in the Mn exposed group than in the control group (MnB 0.81 v 0.68 microgram/100 ml; MnU 0.84 v 0.09 microgram/g creatinine). On an individual basis, MnU and MnB were not related to various external exposure parameters (duration of exposure, current exposure, or lifetime integrated exposure to airborne Mn). On a group basis, a statistically significant association was found between MnU and current Mn concentrations in air. No appreciable difference between the exposed and the control workers was found with regard to the other biological measurements (calcium, LH, FSH, and prolactin in serum). Although the erythropoietic parameters and serum iron concentration were in the normal range for both groups, there was a statistically significant trend towards lower values in the Mn exposed workers. The prevalences of reported neuropsychological and respiratory symptoms, the lung function parameters, and the audioverbal short term memory scores did not differ between the control and exposed groups. The Mn workers, however, performed the other neurofunctional tests (visual reaction time, eye-hand coordination, hand steadiness) less satisfactorily than the control workers. For these tests, the prevalences of abnormal results were related to the lifetime integrated exposure to total and respirable Mn dust. On the basis of logistic regression analysis it may be inferred that an increased risk of peripheral tremor exists when the lifetime integrated exposure to Mn dust exceeds 3575 or 730 micrograms Mn/m3 x year for total and respirable dust respectively. The results clearly support a previous proposal by the authors to decrease the current time weighted average exposure to Mn dust.

Severe uveitis is a relatively common and difficult clinical management problem in ophthalmology. Recently, cyclosporine-A (Cs-A) has been shown to be of therapeutic benefit in the management of sight threatening inflammatory eye disease. In order to examine the efficacy and long term safety of Cs-A, we conducted an open uncontrolled study in 22 patients with sight threatening uveitis whose disease had previously been refractory to treatment with systemic corticosteroids (22 patients), azathioprine (5 patients) and cyclophosphamide (2 patients). Uveitis was idiopathic in 16 cases, one patient had Reiter's syndrome, two had Vogt Koyanagi Harada disease and one patient had sarcoidosis. There were twelve males and ten females with a mean age of 40.5 years (range 22-67 yrs). Nineteen patients (86%) showed significant clinical improvement after treatment with Cs-A (10 mgm/kg/day) with decreased inflammatory activity and improved visual acuity. Three patients failed to respond to Cs-A therapy, while 4 subjects whose disease had initially responded to Cs-A relapsed on attempted withdrawal of this medication. Side effects were common in patients receiving Cs-A [5 mgm/kg/day (or greater)], with hypertension, tremor, hirsutism and raised serum creatinine being most frequent. We conclude that CS-A is an effective immunosuppressive agent in the treatment of patients with uveitis; however, its usefulness is limited by frequent side effects and disease relapse on attempted drug withdrawal.

Ten patients with severe progressive systemic sclerosis were treated with cyclosporin A at dosages of 1.5-7.5 mg/kg per day:two patients showed a marked improvement with softening of the involved skin; in one patient there was healing of persistent digital ulcers; one patient showed initial improvement followed by a marked exacerbation; one patient was slightly improved; two patients were unchanged. The clinical results correlated well with levels of serum aminoterminal propeptide of type III procollagen. In the eight patients completing treatment, side-effects such as slight tremor and a transient increase in the serum creatinine and blood pressure were either absent or reverted to normal when the dosage was decreased, except one case who had to be treated with anti-hypertensive drugs.

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.

A lithium long-term catamnesis of 124 patients (107 manic-depressive and 17 schizoaffective psychoses) after more than 8 years of lithium prophylaxis led to the following results: 1.) Recovering: 30.3%. Improvement - particularly mitigation of the episodes of illness -: 56%. Lack of efficiency: 13%. Mean incidence of episodes of illness before lithium 0.57 per year, during lithium 0.36. Mean incidence of hospitalisation before lithium 3.4 years, during Lithium 7.1 years. Deterioration following discontinuation of lithium: 21 of 22 cases. 2.) Side effects at the beginning: 61.2%, finally 42.7% (incidence of struma 19.5% of tremor 19%, of polydipsia/polyuria 9.1%). 3.) EEG changes (general slowing-down and dysrhythmia, to a quarter focally accentuated): 59%. 4.) Normal results of haematologic and clinical-chemical investigations (28 parameter) except serum creatinine (10%), creatinine clearance (20.5%) and leucocytosis (13%). The authors discuss the reduced incidence of recovery and the quantity of side effects based on the aspect of long-term catamnesis. Further studies are necessary with regard to the selection of lithium-treated patients, to the duration of prophylaxis without efficiency and to the shift from initial efficiency to later inefficiency.

To determine the role played by stagnant peritoneal fluid layers in the diffusion of solutes between peritoneal cavity and blood, we measured peritoneal transfer of urea, creatinine, [14C]-L-glucose and protein in anesthetized rats shaken at varying rates on an orbital platform shaker. The diffusion transfer rates of the low molecular weight solutes increased dramatically with shaking, with near maximal values obtained at a shaking rate of 250 RPM. The permeability area product (PA) for each of the low molecular weight solutes increased about fourfold with rapid shaking while the PA of protein increased by only about 50%. It seems likely while the PA of protein increased by only about 50%. It seems likely that shaking increased PA primarily via reduction of the thickness of stagnant peritoneal fluid layers, although increases in surface area or changes in tissue permeability cannot be excluded with certainty. We conclude that stagnant fluid layers probably are the rate limiting step in diffusive peritoneal transfer of low molecular weight solutes in stationary rats.
