Physical and psychological effects of occupational stress were examined in a sample of 552 female blue collar employees of a microelectronics facility. After controlling for demographic and biological risk factors, non-work life events, and solvent exposure, job-related conflict was associated with depressive symptomatology, severe headaches, lightheadedness weakness/fatigue, rashes, and presence of multiple symptoms. Job demands were only associated with multiple symptoms. Solvent exposure did not interact with either of the job stress measures synergistically to increase symptom reports. Although the main effects of social support, when present, were in the direction of reducing symptomatology, the interactive effects of social support and stress on health were inconsistent and dependent on the source of support.

Cilazapril is a new once-daily angiotensin-converting (ACE) enzyme inhibitor which has been administered to 4,500 patients with mainly mild to moderate essential hypertension in a multinational clinical research program. Sitting diastolic blood pressure was reduced by about 9 mm Hg from baseline (p less than 0.01) after 4 weeks of treatment with cilazapril 1.25-10 mg/day in double-blind placebo-controlled studies. Total responder rates to cilazapril were usually 50-60% compared with 30% to placebo. Adding hydrochlorothiazide 12.5 mg/day to cilazapril 5.0 mg/day increased the total responder rate from 52 to 71%. Double-blind dose titration studies for 8 weeks showed that cilazapril 2.5-5 mg/day possessed equivalent efficacy to usual therapeutic regimens of sustained release propranolol, captopril, hydrochlorothiazide, atenolol and enalapril, Cilazapril did not affect heart rate. During long-term open administration for 52 weeks, or longer, cilazapril, either alone or in combination with hydrochlorothiazide, effectively maintained control of blood pressure. Treatment of patients with severe hypertension with cilazapril plus hydrochlorothiazide achieved a total responder rate of 73%. Adverse events were mostly observed within the first 8-16 weeks of treatment, with headache, dizziness, fatigue, nausea, cough and chest pain being the most frequent. Non-life-threatening angioedema, facial edema and mild hypotension occurred in less than or equal to 0.2% of patients, and orthostatic hypotension was reported in 2%. Abnormal laboratory test values were rarely found with cilazapril treatment. Of the 2.3% of patients with elevated serum creatinine, at any time point during the study and irrespective of outcome on continuation with cilazapril therapy, about two thirds had prior renal impairment.(ABSTRACT TRUNCATED AT 250 WORDS)

We compared the safety of a new dihydropyridine calcium entry blocker, isradipine, with an equipotent dose of diltiazem in 174 mild hypertensives (diastolic blood pressure [DBP] 95 to 105 mm Hg). After appropriate washout and placebo periods, patients were randomly assigned to receive either 1.25 mg isradipine twice daily (Group I) or 40 mg diltiazem thrice daily (Group D). If DBP remained above 90 mm Hg, doses were increased to a maximum of 5 mg isradipine twice daily or 120 mg diltiazem thrice daily. Active therapy was given for a total of 12 weeks. Only 18 patients (nine from each group) did not complete the protocol. The patients were well-matched at baseline with a mean BP of 149/100 mm Hg for those who were randomized to isradipine and completed the protocol and 153/99 mm Hg for the diltiazem group. The responses to each drug were excellent with 72% of the isradipine patients and 73% of the diltiazem group having DBP less than 90 mm Hg at the completion of the study. Of the 156 patients who completed the protocol, only 18 patients (ten in Group I and eight in Group D) failed to respond. Both drugs were well-tolerated. No adverse reactions were reported by 68 percent of the patients in Group I and 65% of those in Group D. The most common side effect was headache (9.0% in Group I and 7.8% in Group D) followed by fatigue (5.2% in Group I and 3.9% in Group D). Age and race did not predict response to either agent but men responded slightly better to diltiazem than women. We conclude that isradipine and diltiazem are equally well tolerated and can be used successfully as a monotherapy to treat hypertension in a wide variety of patients.

During the past decade, the development of various gonadotrophin-releasing hormone (Gn-RH) agonists, which induce reversible hypo-oestrogenism has opened a new area in the medical management of endometriosis. In an open, multicentre phase III study, the efficacy, tolerance and safety of the Gn-RH agonist leuprorelin acetate were tested. The preliminary results of 104 women treated in seven German centres are presented. Pelvic endometriosis was diagnosed by laparoscopy and classified according to the American Fertility Society scoring system: 33% of patients had minimal, 22% mild, 28% moderate and 8% severe endometriosis and in 9% no pathological results were obtained. The patients' mean age was 30 +/- 6 years and 66 had infertility problems. Treatment was started within the first 3 days of the menstrual cycle and consisted of a subcutaneous injection of leuprorelin acetate 3.75 mg, repeated once monthly over 24 weeks. A follow-up period of 12 months after the last injection has been completed in 70 patients, including a second laparoscopy. At all visits, symptoms were evaluated, physical examinations performed, and blood samples collected for haematological screening, serum chemistry determinations and measurement of the gonadotrophins oestradiol and progesterone and leuprorelin acetate. The median score at laparoscopy fell from 12 before operation to 8 after operation and 2 after treatment with leuprorelin acetate. Of the total number of patients, 89% had improvements in their endometriosis, 8% a deterioration and 3% no change. Patients reported improvement in the following: dysmenorrhoea 93%, dyspareunia 62% and pelvic pain 70%. However, all women complained of at least one of the following symptoms: hot flushes 86%, sleep disturbance 62%, sweating 61%, headache 41%, nausea 32% and depression 20%. Fifty-five percent of patients reported additional side effects such as vaginal dryness, fatigue and lower abdominal pain. After the third injection, amenorrhoea persisted in 94% of the women. Four weeks after the first leuprorelin acetate injection median concentrations of oestradiol fell from 45 pg/ml to 11 pg/ml, follicle-stimulating hormone from 7 U/L to 3 U/L and luteinising hormone from 5 U/L to 1 U/L and remained almost unchanged over the observation period. During the 6 months' treatment, laboratory parameters showed no significant deviations from normal; only total cholesterol, high-density lipoprotein cholesterol and alkaline phosphatase increased. Treatment results were judged as good and satisfactory in 82% and 11% of cases, respectively. On the basis of this study, it can be concluded that leuprorelin acetate treatment is safe, well tolerated and effective in the medical management of endometriosis and endometriosis-related complaints.

We report here the effects of in vivo administration of recombinant interleukin-1 alpha (rIL-1 alpha) to patients with severe, idiopathic aplastic anaemia. Four patients who were refractory to immunosuppressive therapy and were not bone marrow transplantation candidates received daily doses of 0.03 microgram/kg and 0.10 microgram/kg intravenously as 5 d courses. No significant changes in either peripheral blood counts or bone marrow cellularity were observed at either dose during or following therapy. Two patients showed increased numbers of bone marrow progenitor colonies. Lymphocyte phenotyping demonstrated an elevated percentage of CD8+/DR+ activated suppressor T lymphocytes prior to therapy. After rIL-1 alpha administration, the percentage of CD8+/DR+ cells was reduced or returned to normal in all patients. Significant side-effects included fever, rigours, fatigue, headache and nausea. Transient hypotension was observed at both doses in all patients. These results suggest that while rIL-1 alpha can be safely administered, no significant haematologic improvement was observed in patients with severe aplastic anaemia.

Gliadin antibodies of the IgG and IgA isotypes and IgG subclasses were measured in 200 adults who were randomly selected from the Icelandic National Register. Those with the highest gliadin antibody concentrations were invited with negative controls to participate in a clinical evaluation. Neither the study subjects nor the physicians who recorded and evaluated the clinical findings were aware of the antibody levels. Significantly higher proportion of the gliadin antibody positive individuals reported unexplained attacks of diarrhoea (p = 0.03), and IgA gliadin antibodies were associated with increased prevalence of chronic fatigue (p = 0.0037). The gliadin antibody positive group also showed significantly decreased transferrin saturation, mean corpuscular volume and mean corpuscular haemoglobin compared with the gliadin antibody negative controls. Serum folic acid concentrations were significantly lower in the IgA gliadin antibody positive individuals. On blind global assessment 15 of the 48 participants were thought to have clinical and laboratory features that are compatible with gluten sensitive enteropathy, and 14 of these were in the gliadin antibody positive group (p = 0.013). Complaints that have not been associated with gluten intolerance had similar prevalence in both groups with the exception of persistent or recurrent headaches that were more common in the gliadin antibody positive group. These findings raise the possibility that a subclinical form of gluten intolerance may be relatively common.

Nine patients with a recurrent malignant glioma were treated with repeated intracavitary or intracerebroventricular injections of human recombinant interleukin-2 (rIL-2) alone or in combination with systemic interferon-alpha (IFN-alpha). Five patients received only rIL-2 and four were treated with rIL-2 plus subcutaneous injections of IFN-alpha. Therapy was administered on a Monday, Wednesday, Friday schedule for up to 10 weeks, beginning with a dose of 10,000 IU rIL-2/injection. Doses were escalated every two weeks until some toxicity was apparent. The maximum amount of rIL-2 any one patient in this group received was 580,000 IU. Patients on combination immunotherapy were held at an rIL-2 dosage of 10,000 IU while IFN-alpha, which began at 3 million IU, was escalated every other week up to 18 million IU/dose. They were then held at that IFN-alpha dosage and rIL-2 was increased to 50,000 IU. The total amount of rIL-2 and IFN-alpha any one in this group received was 510,000 IU and 417 million IU, respectively. Repeated injections of 10,000 IU rIL-2 were well-tolerated by all nine patients and no change in their functional status was seen. At doses at 50,000 IU rIL-2, increased edema around the tumor cavity was observed by MRI/CT scand in 3/5 patients and clinical side-effects in the form of somnolence and headache along with some morbidity specifically associated with tumor location were also seen. Patients receiving rIL-2+ IFN-alpha showed progressive fatigue, muscle weakness, and occasionally nausea. Two of these patients showed increased peritumoral edema on MRI/CT scan.(ABSTRACT TRUNCATED AT 250 WORDS)

We report a case of cerebral tuberculosis following miliary tuberculosis. A 54-year-old man was admitted to our hospital in October 1990 because of fever and general fatigue. Chest x-ray film on admission showed diffuse granular shadows in both lungs. Tubercle bacilli were seen in the sputum (Gaffky 5) by the Ziehl Neelsen's staining, and anti-tuberculous therapy was quickly started. But a few days after admission, the disturbance of consciousness, neck stiffness, and headache appeared. The examination of cerebrospinal fluid disclosed that leucocytes was increased in number, and that ADA was elevated to 14.6 IU/l. Tubercle bacilli were detected from cerebrospinal fluid by culture. Although CT scan of the brain was normal at first week of admission, brain CT at eighth week of admission showed several nodulus enhanced with contrast medium. The findings were confirmed by T2 weighted magnetic resonance images (MRI) as high intense areas. Although T1 weighted MRI showed isointensity of the gray matter, T1 weighted MRI enhanced by Gd-DTPA revealed abnormal enhancement. At twenty-ninth week of admission CT showed no abnormality even by contrast enhancement, but enhanced T1 weighted MRI revealed a small lesion with enhancement which was not shown by CT. MRI enhanced by Gd-DTPA was more useful for evaluating cerebral tuberculosis than brain CT.

The application of recombinant DNA technology to the production of tumor necrosis factor has resulted in the availability of large quantities of a highly purified protein product. This product has been evaluated extensively in preclinical studies, which have documented a direct cytostatic and cytotoxic effect on human tumor cells, as well as a variety of immunomodulatory effects on various immune effector cells, including neutrophils, macrophages, and T cells. In addition, a number of anti-infective and metabolic effects have been documented. In addition to its in vitro effects, rTNF has been shown to have antitumor activity in vivo in preclinical studies involving both transplantable murine tumors and human tumor xenografts. Such observations have led to the evaluation of rTNF as a potential antineoplastic agent in humans. Both single- and multiple-dose phase I studies have confirmed that rTNF can be safely administered to patients with advanced malignancies in a dose range associated with anticancer effect without concomitant serious toxicities such as shock and cachexia. The most commonly observed clinical toxicities include constitutional symptoms, such as fever, chills, headache, and fatigue, and toxicities, which can be at least partially controlled with concomitant administration of nonsteroidal anti-inflammatory drugs, such as acetaminophen and meperidine. Hypotension, which occurs at high doses administered by short intravenous infusion, can usually be prevented by prehydration with intravenous fluids or otherwise controlled by the administration. An intense local inflammatory reaction at the injection site as well as thrombocytopenia appear to be the dose-limiting toxicities after subcutaneous and intramuscular administration. Neurologic toxicity is infrequent, except following continuous intravenous infusion, where it may manifest as transient focal neurologic deficits or seizure. Prolonged administration of rTNF at higher doses may be associated with transient, subclinical decreases in diffusing capacity. Patients with underlying cardiopulmonary disease should be excluded from rTNF therapy in future clinical studies until the end-organ toxicities of this agent are better defined. For at least one preparation of rTNF there appears to be no evidence for the formation of antibodies to rTNF in patients who receive multiple administrations of the agent. Pharmacokinetic studies have shown a relatively rapid clearance following intravenous infusion with a half-life of 15 to 30 min and dose-dependent pharmacokinetics. rTNF can be detected in the serum following intramuscular or subcutaneous injection at only relatively high doses, suggesting a decreased bioavailability with the routes of administration. Early phase I studies defined tolerable dose ranges for each route of administration and began to explore immunomodulatory and metabolic effects of rTNF.(ABSTRACT TRUNCATED AT 400 WORDS)

Fifty-one patients suffering from soft tissue injury of the cervical spine underwent clinical and psychometric examination. Clinical interview evaluated subjective complaints and formal testing of self-estimated cognitive impairment, divided attention, and speed of information processing. Results indicated at least two different syndromes: 1) the "cervicoencephalic syndrome," characterized by headache, fatigue, dizziness, poor concentration, disturbed accommodation, and impaired adaptation to light intensity; and 2) the "lower cervical spine syndrome," which is accompanied by cervical and cervicobrachial pain. When comparing patients with either of these two syndromes, those suffering from cervicoencephalic syndrome had significantly poorer results when tested for divided attention. Speed of information processing was reduced to a comparable extent in both syndromes. These findings were not related to the length of the post-traumatic interval. Reduced processing of working memory is assumed, which may account for more global cognitive problems as well as secondary neurotic reaction.
