A double-blind parallel group study was undertaken during May and June 1985 to compare the effect of nedocromil sodium (1% nasal spray) and placebo, taken twice daily, in relieving the symptoms of rhinitis caused by birch pollen. Two centres were involved. The 54 patients studied had a history of rhinitis in 2 previous birch pollen seasons and positive skin tests to birch pollen. Patients were treated for 4 weeks, but to compare the effects of the 2 treatments the peak pollen periods were used. For dairy card symptoms, results in the 2 centres differed: in Tampere, there were trends in favour of nedocromil sodium with respect to itching (P = 0.04, sneezing (P = 0.06) and total symptoms (P = 0.09); in Oulu no significant differences were seen. Nasal peak expiratory flow rates were slightly better in the nedocromil sodium group. In respect of antihistamine usage, results in the 2 centres were similar and significantly more were used in the placebo group (P less than 0.01). At the end of the trial, both the patients' and the investigators' opinions of treatment effect favoured nedocromil sodium. There were no serious side effects. The results suggest that nedocromil sodium 1% nasal spray, when given twice daily, is effective in the treatment of seasonal allergic rhinitis.

We report our experience in the treatment of two patients with aquagenic pruritus of the elderly and two patients with aquagenic pruritus. Our findings confirm previous reports by others indicating that aquagenic pruritus is not one homogenous entity but rather is composed of two similar but distinct entities, each of which responds to a different treatment. Patients with aquagenic pruritus were helped by adding sodium bicarbonate to the bath water while patients with aquagenic pruritus of the elderly responded to emollients. It is suggested that aquagenic pruritus and aquagenic pruritus of the elderly are two similar but distinct entities. Separating these two entities provides the key to successful treatment, because each of them responds to a different treatment without crossover. This report is only the second report indicating the effectiveness of sodium bicarbonate baths in patients with aquagenic pruritus. It is clear that further examples are needed to confirm these findings.

Seventy seven patients affected by postphlebitic syndrome (PPS) during acute inflammatory and/or obstructive complications were controlled. Thirty nine patients were treated with a new low molecular weight heparin (Fluxum), 16,000 I.U. AXa/day subcutaneously for 10 days and, subsequently, 8,000 I.U. AXa/day subcutaneously for up to 50 days. Thirty eight patients were treated with 20,000 I.U./day i.v. for 10 days of sodium heparin and, subsequently, with 12,500 I.U./day of calcium heparin by subcutaneous injection for up to 50 days. Clinical symptoms (pain, oedema, hyperemia, rashes, itching, dermatitis, ulceration) and instrumental patterns (Doppler) were recorded. Fluxum had an evident effect on the improvement of patient's clinical performance during acute complications of PPS.

To determine whether intrathecal morphine is effective in decreasing analgesic and antihypertensive drug requirements after coronary artery bypass (CAB) surgery, a prospective, randomized, double-blind study was designed. Approximately 30 minutes before induction of anesthesia with IV sufentanil and diazepam, and 2 hours before heparinization, one group of patients (n = 16) were given morphine 0.5 mg, while the control group (n = 14) were given placebo intrathecal injections through 22- or 25-gauge lumbar puncture needles. Intraoperatively, there were no differences in the numbers of patients requiring vasodilator drugs or volatile agent titration. During the postoperative period, the treated group required significantly less (P less than 0.05) IV morphine compared with the placebo group, during the first 24 hours (1.8 +/- 0.7 vs 5.4 +/- 1.5 mg) and 30 hours (2.4 +/- 0.8 vs 8.3 +/- 1.9 mg). The treated group also required significantly less (P less than 0.05) sodium nitroprusside in the first 24 hours (58.1 +/- 29.0 vs 89.1 +/- 18.4 mg). There were no differences in pain scores, and the only complications (itching, nausea and vomiting) were infrequent. It is concluded that an intrathecal dose of 0.5 mg of morphine is efficacious in reducing analgesic and antihypertensive drug requirements after CAB surgery. Whether these results are clinically important enough to warrant the theoretical risks of postheparinization lumbar hematoma is a topic for further investigation.

The efficacy of topical sodium cromoglycate and medrysone was evaluated in 38 patients suffering from atopic keratoconjunctivitis. It was found that medrysone (1%) significantly improved the symptoms of itching, watering, photophobia and hyperaemia, while sodium cromoglycate (2%) was found to be ineffective. Tear prostaglandin E2 and histamine levels did not decrease significantly after sodium cromoglycate therapy. The findings of the present study reveal that sodium cromoglycate has no significant role in the management of atopic keratoconjunctivitis.

In a 48-week, double-blind trial, 122 patients were randomly assigned to treatment with auranofin (60) and gold sodium thiomalate (GST) (62) at five centers. Both groups showed significant improvement (P less than 0.05) from baseline in parameters of disease activity. Results of the covariance analysis for all patients who completed the trial showed no significant differences (P less than 0.05) in efficacy between the two groups. The proportions of patients showing 50% or greater improvement in tender joints, swollen joints, activity index, severity of pain, general health rating, and erythrocyte sedimentation rate (ESR) were similar for both auranofin-treated and GST-treated patients who completed the 48-week trial. When all patients who entered the trial were evaluated, a slightly greater proportion of patients on auranofin had improved. Diarrhea occurred more frequently with auranofin (32%) compared to GST (19%), whereas rash and pruritus were twice as common in those patients treated with GST compared to those treated with auranofin. The withdrawal rate due to adverse reactions was 10% for auranofin vs 26% for GST. It was concluded that the efficacy of auranofin was comparable to that of injectable gold and was better tolerated, as evidenced by the lower withdrawal rate from adverse events for the auranofin patients.

In a double-blind parallel group comparison of efficacy and safety, 19 patients with peri-arthritis of the shoulder received 200 mg fentiazac twice daily and 19 received 50 mg diclofenac sodium twice daily, with both drugs given orally for 3 weeks. In both groups, observers' verbal rating scales of pain severity at rest and on movement showed decreases that were significant by week 1. Both groups also had significant improvement in abduction, external rotation, retroversion and anteversion. At week 1, the patients reported improvement, on a verbal rating scale, of global effectiveness, but there were no subsequent changes. There were no statistically significant differences between the treatments in any of these variables. Five (26%) fentiazac-treated patients and four (21%) diclofenac sodium-treated patients reported adverse effects, mostly gastro-intestinal. One case of rash in each group and one case of pruritus in a diclofenac sodium-treated patient were severe enough for the patients to be withdrawn from therapy. There were no clinically significant changes in laboratory values. It was concluded that fentiazac (400 mg/day) and diclofenac sodium (100 mg/day) were equally effective within 1 week in decreasing pain severity and improving shoulder mobility.

A health survey was conducted among spraymen exposed to 2.5% deltamethrin EC in the cotton fields. The subjects were exposed to deltamethrin at concentrations of 0.022-24.070 micrograms/m3 in respiratory zone air and of 0.013-0.347 micrograms/cm2 of skin contact. Results showed that one-half of the 44 subjects examined complained of itching and burning sensations on their faces. A few miliary red papules also appeared on the face of one subject but not sign of acute deltamethrin poisoning was evident on physical examination. There were no significant differences between the subjects examined and the controls in sodium, potassium, and urea contents in the serum, sodium potassium ATPase and serotonin in whole blood, and 3-methyl-4-hydroxymandelic acid and 5-hydroxyindoleacetic acid in the urine. Deltamethrin in the urine of spraymen was below the detection limit (0.20 microgram/liter) of the method used.

Subjective (sensory) irritation was studied with lactic acid test on 74 females; 8 reacted positively with "stinging" and/or itching or burning and another 5 had mild subjective sensations. History of previous corresponding sensations from contact with cosmetic products was significantly more common in stingers than in non-stingers (p less than 0.001); other factors, such as dermatologic history, sensitivity to ultraviolet light or skin dryness had no characteristic patterns. In the objective, immediate non-immunologic contact urticaria tests with sorbic acid and benzoic acid, the stingers developed significantly more erythema to 0.5% sorbic acid (p less than 0.05) and to 1% benzoic acid (p less than 0.02). 1% sorbic acid also induced more edema in stingers (p less than 0.02). Increased reactivity to a 24 h sodium lauryl sulfate (SLS) patch test was demonstrated only with laser Doppler velocimetry (p less than 0.05). Stingers and non-stingers reacted similarly to open, cumulative SLS irritation as measured with transepidermal water loss. These studies provide clinical and biological information about subjective irritation; the data suggest a functional correlation for the what had been considered a purely subjective (sensory) phenomena.

A case of phenytoin-induced hepatitis with mononucleosis is reported, and syndromes associated with phenytoin hypersensitivity reactions are discussed. A 23-year-old black woman with a two-month history of seizure disorder was admitted to a hospital with nausea, vomiting, fever, lymphadenopathy, diffuse maculopapular rash, left-upper-quadrant tenderness, and hepatomegaly. She was receiving phenytoin sodium 300 mg/day; carbamazepine 200 mg four times daily had been discontinued four days before admission because of leukopenia. Phenytoin was discontinued after admission; however, phenytoin 1 g i.v. was given for a tonic-clonic seizure two days after admission, after which swelling of the face and legs and pruritus developed. Over the next few days, signs and symptoms of hepatotoxicity progressed, and she became comatose. Seizures were treated with diazepam. She began to recover after 10 days of supportive therapy and was discharged several weeks later on primidone therapy. Serious phenytoin hypersensitivity reactions may appear as dermatologic, lymphoid, or hepatic syndromes. Fever, rash, and lymphadenopathy often accompany hepatic injury. Encephalopathy and death may occur. Proposed mechanisms for phenytoin hypersensitivity include antigen-antibody reactions, alteration of lymphocyte function, and an enzyme abnormality causing the production of toxic metabolites. Treatment is supportive; phenobarbital and carbamazepine may be used with caution as alternate anticonvulsant therapy. The possibility of phenytoin hypersensitivity reactions should be considered when patients receiving phenytoin have unusual symptoms, particularly fever, rash, and lymphadenopathy.
