A heavy infestation of the tussock moth caterpillar (Orgyia pseudotsugata McDonnough) in forested areas of Oregon was associated with itching of the skin and eyes, nasal discharge, cough, and, at times, respiratory difficulty, Personal interviews and inspection of forty-one occupationally exposed persons were supplemented by a questionnaire administered to 428 individuals, composing three groups at various degrees of risk and a control group. There was a cause and effect relationship between the adverse symptoms and the exposure to tussock moth larvae. The specific etiologic agent was not identified, but it was felt that the secretion, hairs, or other substances in the larvae or cocoons of the moth acted as a potent allergenic substance and, for some persons, was also a primary skin irritant.

A survey was made on workers handling powdered drugs in a pharmaceutical factory. In this factory, two kinds of anti-inflammatory enzyme (bromelain and trypsin), one anti-inflammatory agent (flufenamic acid), one antispasmodic (flopropion) and two kinds of antibiotics (ampicillin and cephalexin) are mainly produced. Twenty four workers were examined by interviews and checked by Cornell Medical Index, and 18 of them complained of respiratory symptoms. These 18 workers were physically examined by skin scratch tests, pulmonary function tests and serum immunological tests. Among 24 workers, 9 handled powdered drugs (A group), 5 handled the same in the past and had already been transferred to other sections for their symptoms (B group), 3 engaged in the process of capsul-filling (C group) and 7 handled several times occasionally during one year (D group). Their average months spent in handling powdered drugs were, in the case of anti-inflammatory enzyme, A group 53.2, B group 66.2, and in the case of antibiotics, 5 workers in A group 24.0, 2 workers in B group 7.0, 3 workers in C group 25.7. Twenty workers complained of symptoms which were mainly irritation of mucosa including the respiratory system and itching of the skin while they were working, and accelerated nasal discharge, urticaria and asthma after working. Group A and group B were higher than group D in the rate of respiratory complaints in C.M.I. (p less than 0.001). Fourteen workers pointed out anti-inflammatory enzyme as a cause of main symptoms, 7 workers flufenamic acid, 3 workers flopropion, 4 workers antibiotics. Three workers who had past history of asthma or articular rheumatism had been transferred to other sections. Of 18 workers who were physically examined, 11 workers showed positive reactions to skin scratch tests with handling drugs. On 8 workers of them, some kinds of drugs which were pointed out as drugs causing main symptoms reacted positively. Numbers of workers with increased immunoglobin values were, IgE 3, IgM 2, IgA 4, IgM 2. Two workers showed decreased FVC and FEV (1.0 sec.) values in pulmonary function tests. The causes of the occupational allergic reaction in this factory are guessed as follows: 1) control of powdered materials was incomplete in the process of production, 2) various kinds of sensitizing drugs were handled by the same workers.

A randomized, double-blind, placebo-controlled, parallel group study was conducted in 11 centers to evaluate the safety and efficacy of a once-a-day regimen of 110 micrograms, 220 micrograms; and 440 micrograms of triamcinolone acetonide intranasal aerosol versus placebo in relieving the symptoms of rhinitis in 305 adult and older pediatric patients with perennial allergic rhinitis. Nasal stuffiness, nasal discharge, sneezing, nasal itching and the nasal index (the sum of the mean scores of the first three symptoms) averaged over the first 6 weeks and second 6 weeks of the study were significantly reduced in patients who received the 220 micrograms/day and the 440 micrograms/day dosages. The 110 micrograms/day group had a reduction in these nasal symptoms, but only the sneezing and nasal index were significantly (P less than .05) better than placebo. During the last 6 weeks of the study, patients were allowed to take oral back-up medication for their nasal symptoms; all three groups receiving triamcinolone nasal aerosol took less back-up medication than did the placebo group. There were no significant adverse effects or laboratory abnormalities noted during this study. Intranasal triamcinolone acetonide 220 micrograms and 440 micrograms, used once-a-day for 12 weeks is clinically and statistically superior to placebo for the treatment of perennial allergic rhinitis.

Two hours after ingestion of improperly cooked meat a German tourist in Tunisia showed coughing, hoarseness, dysphagia, anosmia, frontal headache and epistaxis. At the same time a papular non-itching exanthema developed. The nasal discharge contained nymphs of Linguatula serrata. Histological examination of the papules revealed tissue eosinophilia and 'flame figures'. Nasopharyngeal and skin signs subsided spontaneously within 10 days. The possible role of major basic protein in the pathogenesis of nasopharyngeal linguatulosis is discussed.

The possible role of leukotriene D4 (LTD4) in nasal allergy was investigated in healthy volunteers. Nasal blood flow, nasal airway resistance, nasal discharge and nasal itching and sneezing were examined. LTD4 was found to induce a dose-response related increase in nasal mucosal blood flow as measured by laser-Doppler flowmetry. Histamine exhibited similar effects on blood flow in the same concentration range. Nasal airway resistance as recorded by rhinomanometry, increased in a dose-related manner after topical LTD4. Nasal secretion was obtained by nasal lavage and estimated from a dilution principle. Topical LTD4 did not increase the amount of nasal secretion, whereas a dose-related increase was found after topical histamine. LTD4 did not cause itching, sneezing or other irritative symptoms. In conclusion, LTD4 may play a role in nasal allergy by increasing blood flow and nasal airway resistance. Itching, sneezing and discharge, however, are apparently not caused by LTD4 but can be accounted for by the release of histamine or other mediators.

A total of 317 patients received loratadine, 10 mg once daily, terfenadine 60 mg twice daily, or placebo in a 14-day, double-blind, randomized study in seasonal allergic rhinitis. Four nasal and four nonnasal symptoms were evaluated. At the end point evaluation, mean total scores of combined nasal and nonnasal symptoms decreased from baseline (improved) 46%, 44%, and 35%, respectively, for loratadine, terfenadine, and placebo. The difference between loratadine and placebo treatment was significant (p = 0.03). Loratadine was particularly effective compared with placebo in relieving nasal discharge, sneezing, and itching/burning eyes. Therapeutic response to treatment was good or excellent in 66 (64%) of 103 loratadine-treated patients, 58 (56%) of 104 terfenadine-treated patients, and 48 (47%) of 102 placebo-treated patients. Adverse experiences reported during the study were usually mild or moderate and were not significantly different among the three treatment groups. Sedation (somnolence) was reported by 10 loratadine-treated patients, seven terfenadine-treated patients, and eight placebo-treated patients. Loratadine, 10 mg once daily, was comparable to terfenadine, 60 mg twice daily, and significantly superior to placebo in the symptomatic relief of seasonal allergic rhinitis.

Forty-four patients, with symptoms of nasal obstruction, sneezing, itching and/or rhinorrhea, were entered into a placebo-controlled, double-blind study to evaluate the clinical efficacy of a topical antihistamine drug, levocabastine, applied 4 times a day for 14 days. At the end of the treatment the placebo patients were treated with levocabastine and the levocabastine patients were treated with beclomethasone dipropionate in a single-blind design for another 14 days. This study showed that levocabastine is significantly more active than placebo with reference to nasal discharge and sneezing. Placebo application improved the symptom score. Levocabastine could not be proved to be more effective against nasal obstruction than placebo in the double-blind trial. In the single-blind set-up, levocabastine resulted in an additional improvement in the score for obstruction, after the placebo period. Although the allergic group tended to respond better, no statistically significant difference could be detected between allergic and non-allergic patients. After treatment with levocabastine, beclomethasone dipropionate administration could not improve the results for nasal discharge and sneezing. For nasal congestion, beclomethasone dipropionate proved to be superior to levocabastine.

Otorhinolaryngological manifestations of 13 patients with von Recklinghausen's disease appearing at Lagos University Teaching Hospital over a five-year period have been studied. Among patients with ENT manifestations of the disease, the most common general features exhibited were cutaneous neurofibromas (100 per cent), headache (69.23 per cent) and pruritus (46.15 per cent). But the head and neck findings included external meatal canal stenosis (30.77 per cent), conductive deafness (30.77 per cent), nasal discharge (30.77 per cent), cranial nerve involvement (30.77 per cent) and disfigurement of the soft tissues of the face (30.77 per cent). Involvement of pinna (23.31 per cent), rhinolalia aperta (15.38 per cent), mental retardation (15.38 per cent) and pharyngeal swelling (7.69 per cent) also featured. Clinically detectable bilateral acoustic neurofibromas in adults or astrocytomas in children were not found in this series. Involvement of the frontoparietal bone (7.65 per cent) presented with skull bossing which had to be differentiated from that due to sickle cell disease in the African. There was also a singular case of phrenic nerve involvement. However, malignancy occurred in one (7.69 per cent) of these patients. Thus, it is important always to follow-up these patients closely so as to detect malignant transformation in time.

A group of Angus X Holstein cattle were determined to have allergic rhinitis. Clinical signs included nasal discharge, tearing, sneezing, and nasal pruritus. The diagnosis was made on the basis of intradermal skin testing of affected and clinically normal cattle. The affected cattle had positive test results to various tree, grass, weed, and mold allergens. The clinical signs and seasonal occurrence were similar to those features for allergic rhinitis in man. Breeding data indicated an inherited mode of transmission, although only females were affected.

Allergic rhinitis was identified in a herd of Hereford cattle. Affected cattle had clinical signs of rhinitis (eg, nasal discharge, sneezing, nasal irritation, and nasal pruritus) and multiple small proliferative lesions in the nasal passages. Eosinophils were the predominant cell type in nasal discharges, and histologic examination of nasal mucosa biopsy specimens revealed chronic proliferative eosinophilic rhinitis. Results of CBC were normal; plasma fibrinogen concentrations were within reference limits. Results of intradermal allergen sensitivity testing and an ELISA for allergen-specific IgE only suggested an exaggerated IgE-mediated response to environmental allergens. Allergen-specific IgG may have acted as a competitive blocking antibody and limited clinical signs of disease in some cattle.
