The therapeutic profile of enalapril in mild to moderate uncomplicated essential hypertension was assessed in 265 patients who participated in a multicenter, open-label, prospective study lasting eight weeks. There were 54 younger (aged 39 years or less), 136 middle-aged (40 to 59 years), and 75 older patients (60 years or over). Monotherapy with enalapril in a single daily dosage regimen ranging between 5 and 40 mg resulted in normotension (in the sitting position) in 73% of the younger, 50% of the middle-aged, and 56% of the older patients. Normotension was achieved with 5 mg/day of enalapril in 41%, 18%, and 37% of the subgroups, respectively. Both systolic and diastolic pressures at the end of eight weeks of treatment were significantly lower (P less than 0.01) in the younger patients than in the other two age groups. White patients had significantly greater (P less than 0.001) response of both systolic and diastolic blood pressures than did black patients and required significantly smaller (P less than 0.01) average daily dosages of enalapril (14 mg versus 22 mg, respectively). The overall incidence of side effects was 14% among all 276 patients enrolled in the study. Most were mild and transient, but six patients discontinued enalapril during the first week of therapy because of side effects. There were no cases of rash, dysgeusia, hematological disorders, or deterioration in renal function, but there were two cases of pruritus, one of glossitis associated with an upper respiratory infection, and three of dry cough or wheezing. Angioedema was not observed. Monotherapy with enalapril, usually in a single daily dose of 10 to 20 mg, was effective in inducing normotension in approximately half of the middle-aged and older hypertensive individuals and in nearly three fourths of those below age 40. In this study it was generally well tolerated, with a relatively small incidence of side effects.

Seven subjects, who experienced systemic allergic reactions after the ingestion of a newly marketed food supplement, were evaluated to identify the responsible ingredient. Skin testing with extracts prepared from ingredients in the food supplements revealed marked sensitization of all of the subjects to cottonseed protein. Double-blind, placebo-controlled food challenges performed in two subjects with cottonseed flour produced reactions consisting of oropharyngeal pruritus, rhinitis, nausea, diaphoresis, dyspnea, cough, and a fall in pulmonary function tests of 45% or more. All placebo challenges were negative. Because of the reactions observed during these challenges, other subjects were not challenged orally with cottonseed protein but consumed without incident other ingredients in the supplement to which they were skin test positive. Our evaluation strongly incriminates cottonseed protein as the cause of the systemic allergic reactions in these subjects and is consistent with earlier articles in the literature describing the potent allergenicity of cottonseed protein.

Rhodamine B is a red colored dye that is used in cosmetic products. We report a case of 17 patients who were exposed to aerosolized Rhodamine B inside a maintenance shop. The mean duration of exposure was 26 minutes (range 2-65). Sixteen of the patients (94%) complained of acute symptoms including: burning of the eyes (82%), excessive tearing (47%), nasal burning (41%), nasal itching (35%), chest pain/tightness (35%), rhinorhea (29%), cough (29%), dyspnea (29%), burning of the throat (24%), burning/pruritic skin (24%), chest burning (12%), headache (6%), and nausea (6%). All of the patients had resolution of their symptoms within 24 hours (less than 4 hours in 63%). Acute exposure to Rhodamine B resulted in transient mucous membrane and skin irritation without evidence of serious sequellae.

One hundred and thirty four ambulatory children with bronchial asthma were investigated in the Pediatric Pulmonary-Allergic Service. In 95 patients an interval characterised by prodromal respiratory symptoms (cough, rhinorrhoea, and wheezing), behavioural changes (irritability, apathy, anxiety, and sleep disorders), gastrointestinal symptoms (abdominal pain and anorexia), fever, itching, skin eruptions, and toothache preceded the onset of the attack of asthma. Each child had his own constant set of prodromal findings. A significant age related increase in serum IgE concentrations was observed in these patients. No such relation was observed in children with an acute onset of attack of asthma without any preceding symptoms. We suggest that awareness of these prodromal symptoms may lead to an early introduction of treatment, thus avoiding or abbreviating some of the acute attacks of asthma.

We describe a patient presenting with painless jaundice, anorexia and pruritus. The gall bladder was found to be lying above and behind a hypoplastic right lobe of liver. There was no evidence of cholangitis or biliary obstruction. The patient subsequently developed a bronchobiliary fistula with severe wheeze, cough and bile-stained sputum. Emergency percutaneous drainage of the gall bladder led to immediate cessation of bronchospasm and biloptysis, rendering the patient fit for definitive surgery.

History of acute symptoms (cough, wheezing, shortness of breath, fever, stuffy nose, and skin itching/rash) following exposure to grain dust was obtained from 661 male and 535 female current and former farmers. These symptoms were relatively common: 60% of male and 25% of female farmers reported at least one such symptom on exposure to grain dust. Association of cough, wheezing, shortness of breath, and stuffy nose with skin reactivity and capacity to form IgE is consistent with an allergic nature of these symptoms. Barley and oats dust were perceived as dust most often producing symptoms. On the other hand, grain fever showed a different pattern, i.e., it was not associated with either skin reactivity or total IgE. Smoking might modify the susceptibility to react to grain dust with symptoms. Only those who reported wheezing on exposure to grain dust may have an increased risk to develop chronic airflow obstruction.

A single capsule of sustained release pseudoephedrine (SUDAFED S.A., Burroughs Wellcome Co.) was shown by objective and subjective measurements to be superior to placebo in relieving nasal congestion associated with allergic rhinitis. The drug had no discernible effect on (1) the degree of wetness perceived in the mouth or nose, (2) a complex of symptoms which included sneezing, coughing, sniffing, swallowing, itching of eyes and nose or (3) number of nose blows. The study was marked by an absence of serious adverse reactions.

Fifteen patients with the hypereosinophilic syndrome were studied during a period of 6.5 years. The mean age at onset was 36 years. Two were female. The commonest presenting symptoms were nocturnal sweating with or without severe coughing attacks, symptoms of cardiovascular disease, anorexia and weight loss, neurological and gastrointestinal symptoms and itching with or without skin lesions. The mean blood eosinophil counts at presentation were 20.1 X 10(9)/l. Eight patients had previous allergic or parasitic disease which could have predisposed them to the development of hypereosinophilia. Eight patients had raised serum immunoglobulin levels: IgM in five, IgE in four and IgG in one. Five of nine patients had raised serum eosinophil cationic protein levels. Episodes of clinical relapse occurred with increased white blood counts and were treated with prednisolone and cytotoxic drugs. Thrombotic and embolic complications developed in 10 patients, despite treatment with anticoagulants and inhibitors of platelet function, and were the cause of death in three. Two patients with severe endomyocardial fibrosis responded well to cardiac surgery, and a third required emergency mitral valve replacement. The 12 surviving patients have lived 0.8-11.5 years (mean 4.4), since the onset of their illness. It is concluded that the hypereosinophilic syndrome has distinctive features with an episodic course. The principal complications affect the cardiovascular system, especially endomyocardial fibrosis and thromboembolic occlusion of large and small blood vessels in many organs. Although treatment is usually effective in overcoming relapses, the underlying disease process appears to be unaffected. Despite this, patients can have prolonged periods of remission and may survive for many years.

Allergic reactions to food colors have been known since 1958. Reactions to tartrazine, our example, include generalized pruritus, urticaria, angioedema, paresthesias, vomiting, migraine, rhinorrhea and nasal obstruction, coughing, asthma attacks and purpura. Many patients who are allergic to antiinflammatory drugs such as acetyl-salicylic acid and indomethacin show cross-reaction to tartrazine. Doses producing these reactions range from minimal amounts up to 750 mg. Symptoms appear after periods of time ranging from minutes to 6 to 14 hours. In view of these facts (some of which represent a threat to the patient's life), additives, colouring matter, etc, do not usually appear in product labels or specifications, or in handbooks or catalogues used in practice. We drew up a list of drugs which may contain food dyes and coloring matter, yellow No. 5. A letter was written to 233 laboratories of which 159 (68%) replied. 72 (45%) in the affirmative and 87 (55%) in the negative, 74 (32%) did not reply.

There is a broad spectrum of disease encompassed by the various forms of eosinophilic pneumonia. Variations in both clinical course and histologic picture make these conditions difficult to classify. A case is reported of an 18-year-old black female, seven weeks postpartum, who presented with distinctive subcutaneous nodules on her extremities. These progressed to include edema and pruritus of both feet and one arm. She had been taking only oral contraceptives for six weeks. While in the hospital, she developed fevers to 104 F, cough, shortness of breath, and eventual respiratory insufficiency requiring intubation and ventilatory assistance. Chest x-ray films revealed diffus infiltrates. Lung biopsy revealed chronic interstitial organizing pneumonia with vasculitis and marked eosinophilia. She responded dramatically to high dose steroids and recovered. After careful literature review, this case fits best in the category of Carrington chronic eosinophilic pneumonia. It is unusualy in its dermatologic presentation and its fulminant development of respiratory insufficiency.
