Two cases of occupational asthma due to styrene are described. The subjects complained of cough, breathlessness, and symptoms of asthma when coming into contact with styrene; in patient 1 the respiratory reaction was followed by a late cutaneous rash. The symptoms disappeared when the subjects were away from work on weekends or holidays. In both cases, inhalation challenge with styrene produced an immediate bronchospastic reaction which was followed by a late cutaneous rash in patient 1. Prior administration of disodium cromoglycate (40 mg from a spinhaler) prevented the respiratory reactions completely, but failed to prevent the late skin response in case 1. Styrene removal was followed by complete disappearance of the symptoms. We conclude that styrene can be a primary cause of occupational asthma.

In an ongoing prospective study of homosexual men conducted in Vancouver since November 1982, 87 cases of human immunodeficiency virus (HIV) seroconversion have been documented to date. Comparison of laboratory results obtained a mean of 4.9 months before and 5.4 months after the estimated date of seroconversion revealed that a significant increase in the serum IgG level (from 1149 to 1335 mg/dl on average) and in C1q binding (from 8.8% to 14.2% on average) was associated with early HIV infection (p less than 0.001). A marginally significant decrease in the ratio of helper to suppressor (CD4 to CD8) cells (from 1.55 to 1.29 on average) was also noted (p = 0.025). A marked decrease in absolute number of CD4 cells was not seen with seroconversion, which suggests that profound loss of these cells may be a long-term effect of HIV infection. The occurrence of symptoms (including fatigue, fever, night sweats, unintentional weight loss, diarrhea, joint pains, cough unrelated to smoking, shortness of breath, oral thrush, herpes zoster and rash) did not increase with seroconversion. This finding suggests that most cases of HIV seroconversion may be asymptomatic or associated with relatively minor symptoms. On the other hand, generalized lymphadenopathy was found to develop after HIV seroconversion in about 50% of cases.

This was a study of 50 patients, aged 3 months to 10 years. There were 27 males and 23 females. Symptoms varied from respiratory complaints to rash, headaches, and gastrointestinal symptoms. Twenty-seven patients had runny nose, 15 wheezing, 19 frequent infections, 10 coughing, 10 ear infections, 9 rash, 6 gastrointestinal symptoms, and 6 with headaches. Laboratory evaluation showed that 16 patients had elevated IgE. Forty-six patients had IgE RAST evaluation. Of these, only 17 had positive IgE RAST for foods including corn, egg, wheat, and milk. In contrast, 32 of 46 patients had positive IgG RAST for foods including corn, egg, wheat, and milk. Elimination diet of IgE RAST-positive and IgG RAST-positive foods caused a 70% reduction of symptoms. Although the data suggest that IgG antibodies may be helpful, further studies are warranted.

Rat-bite fever results from an infection with the organism Streptobacillus moniliformis. Symptomatic patients often present with fever, malaise, cough, maculopapular rash, and occasional arthritis, and usually have a history of rodent exposure. This report describes a patient with rat-bite fever resulting in suppurative arthritis. The patient's diagnosis was made by culture of S moniliformis from his left wrist. The diagnosis was delayed, however, owing to the lack of an exposure history, atypical clinical presentation, and the unusual microbiologic characteristics shown by this organism.

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.

In February 1981, a measles outbreak occurred in a pediatric practice in DeKalb County, GA. The source case, a 12-year-old boy vaccinated against measles at 11 1/2 months of age, was in the office for one hour on the second day of rash, primarily in a single examining room. On examination, he was noted to be coughing vigorously. Seven secondary cases of measles occurred due to exposure in the office. Four children had transient contact with the source patient as he entered or exited through the waiting room; only one of the four had face-to-face contact within 1 m of the source patient. The three other children who contracted measles were never in the same room with the source patient; one of the three arrived at the office one hour after the source patient had left. The risk of measles for unvaccinated infants (attack rate 80%, 4/5) was 10.8 times the risk for vaccinated children (attack rate 7%, 2/27) (P = .022, Fisher exact test, two-tailed). Airflow studies demonstrated that droplet nuclei generated in the examining room used by the source patient were dispersed throughout the entire office suite. Airborne spread of measles from a vigorously coughing child was the most likely mode of transmission. The outbreak supports the fact that measles virus when it becomes airborne can survive at least one hour. The rarity of reports of similar outbreaks suggests that airborne spread is unusual. Modern office design with tight insulation and a substantial proportion of recirculated ventilation may predispose to airborne transmission.

The effectiveness and the safety of a new chemotherapeutic phenol derivative, clofoctol, was evaluated in adult hospitalized patients affected by infectious diseases of the bronchopulmonary tract. The clinical diagnosis included acute exacerbation of chronic bronchitis, acute bronchitis, bronchiectasis, pneumonia, bronchopneumonia and lung cavitary neoplasm. Expectoration, cough, dyspnoea, respiratory murmur and body temperature were considered as clinical factors to which an arbitrary score was given. Functional respiratory parameters including FVC, FEV1 and FEV1/FVC X 100 were also evaluated. All the patients were treated rectally with clofoctol 1500 mg daily for five days. Bacterial evidence of infection was obtained by sputum culture, which was repeated at the end of treatment. At that time, bacteriological results were 72.4% disappearance of baseline pathogens, 20.7% persistence of baseline pathogens and 6.9% presence of different organisms. Functional respiratory parameters were found to be significantly improved by treatment. Clinical results, arbitrarily evaluated on the basis of the overall assessment of laboratory and functional data, were excellent in 33.3%, good in 44.4%, fair in 5.6% and poor in 16.7% of patients. Tolerance was generally good; side-effects included maculopapular rash in 2 patients and rectal disturbances in 10 patients. In conclusion, for the treatment of bronchopulmonary diseases clofoctol offers an interesting alternative to antibiotic therapy.

Since 1960, smallpox has been introduced into 10 European countries on 28 separate occasions. Most commonly, the index case was infected in Asia and returned to Europe by air during the period December-May. Subsequent cases have occurred mainly among persons exposed by direct, face-to-face, contact in the household or hospital. Medical and hospital personnel, patients and visitors constituted approximately half of all cases in these outbreaks.In a recent outbreak in Meschede, Federal Republic of Germany, detailed epidemiological studies have clearly indicated that 17 of the cases were infected by virus particles disseminated by air over a considerable distance within a single hospital building. Several features believed to be of importance in this unusual pattern of transmission were common to a similar outbreak in the Federal Republic of Germany in 1961 in which airborne transmission also occurred. These features include a source case with extensive rash and cough, low relative humidity in the hospital and air currents which caused rapid dissemination of the virus. While airborne transmission of this sort is rarely observed in smallpox outbreak, it is important to recognize that it may occur under certain circumstances.Proper vaccination of travellers prior to their departure from their native countries and a regular programme for vaccination of medical and hospital personnel could have prevented at least half of the cases which occurred in Europe during the past decade. Although progress in the global smallpox eradication programme has been accompanied by a decreased frequency of importations into Europe, no country should relax its vigilance until smallpox has been eliminated everywhere.

In children vaccinated with killed measles vaccine, exposure to natural rubeola within two to four years can result in a clinical syndrome of altered measles reactivity.During a small epidemic of measles in Edmonton, Alberta, 51 children who had received their last killed measles vaccination 27 to 45 months before, were admitted to hospital with this syndrome.The syndrome consists of a prodromal cough and high fever followed by a maculopapular rash appearing on the extremities and progressing centrally. Pulmonary consolidations with or without pleural effusions were evident, but these cleared rapidly in four or five days. Initial WBC and ESR values suggested a bacterial etiology, but no pathogens could be isolated.Complement fixation titres for rubeola are present in acute and convalescent sera and indicate a definite measles infection.Previous killed measles vaccination excites a delayed hypersensitivity which is activated by the natural measles infection to account for this syndrome.It is recommended that killed measles vaccine be no longer used in routine vaccinations.

This article reports a case of needlestick transmission of human T-lymphotropic virus type III (HTLV-III) infection to a health care worker in the UK from a patient who was presumably infected while in Africa. The patient, a white woman who had lived in central southern Africa, presented at the hospital with general malaise, dry cough, and fever. Lung biopsy revealed Pneumocystis carinii pneumonia infection, and the patient was seropositive for HTLV-III infection with a titer of 260. The patient reported that she had been unwell for 2-3 years. She had none of the accepted risk factors for acquired immunodeficiency syndrome (AIDS), and neither she nor her husband had visited the US, the Caribbean, or Zaire. Serum from the husband was positive for HTLV-III antibodies at a titer of 450. Despite intensive management and treatment with pentamidine, the patient died. During management of this case, a nursing staff member sustained a needlestick injury to the finger while resheathing a hypodermic needle. A small amount of blood was probably injected. 13 days later, the health care worker developed a severe flu-like illness with sore throat, headache, myalgia, and facial neuralgia. A macular rash and generalized lymphadenopathy were also noted. Serum drawn 27 days after the incident was negative for anti-HTLV-III infection, but titers on days 49 and 57 were 12 and 24, respectively. This contrasts with experience in the US, where needlestick injuries in health care workers have not resulted in either disease or transmission. It is assumed that the patient acquired AIDS in Africa, and that the infection was transmitted heterosexually. This case raises the possibility of differences in infectivity and other characteristics between HTLV-III viruses of US and African origin.
