We reviewed retrospectively 135 cases of serologically-confirmed psittacosis that were admitted to Fairfield Hospital between January 1, 1972 and March 31, 1986. The average age of the patients was 46 years. The majority (85%) of patients described a history of recent exposure to birds. The clinical features, investigations, treatment and subsequent response were analysed in 129 patients. Psittacosis was a well-defined illness that was characterized by an abrupt onset of fever, rigors, sweats, and prominent headache, and a mild dry cough which appeared late frequently. However, respiratory symptoms were absent in 18% of patients. Diarrhoea and sore throat were occasional complaints. Over 90% of cases had an abnormal chest x-ray film, or abnormal chest signs, or a combination of both. Most patients had a normal leukocyte count. Tetracycline drugs were used for treatment in 87% of the patients. Defervescence occurred in 92% of patients after 48 h of tetracycline treatment. There were no recrudescences of psittacosis and no fatalities. The clinical diagnosis of psittacosis can be made early usually, particularly in the presence of pneumonitis on a chest x-ray film and a positive history of bird contact. Treatment with doxycycline (100 mg twice a day for 14 days) is recommended.

Epiglottitis may occur at any age. The typical presentation in the young child and young adult is well known, but the presentation in patients at the extremes of age has not been characterized. At our locale, from 1974 to 1984, 19 children 24 months of age or less and, from 1979 to 1984, 9 adults 50 years of age or greater with epiglottitis were seen in the emergency department. In the infantile group, rapidly progressive interference with swallowing, vocalization, and respiration was encountered in less than half the patients. Symptoms were often prolonged before parents sought attention for their child. No preference was shown for maintenance of the upright position while at rest, as recumbency did not promote stridor or initiate respiratory distress. Respiratory complaints were common and included cough, tachypnea, and retractions. Drooling or retention of pharyngeal secretions was uncommon. The adult population had a history of symptoms that spanned several days. Extreme sore throat, pooling of oral secretions, muffled voice, and elevated temperature were uncommon. Dysphagia and mild respiratory complaints were frequent. Upper airway obstruction did occur. At both extremes of age, exceptions to the classic clinical pattern of epiglottitis occurred with significant frequency. Despite this, diagnosis and management in the emergency department were appropriate in most cases.

A study was undertaken to determine disease prevalence of, choice of treatment for, as well as health services utilization by, preschool children living in a rural district of coastal Tanzania. Disease prevalence and choice of treatment were determined through seven-day recall; health services utilization through systematic analysis of Village Health Workers' service records over one calendar year. It was found that the main disease symptoms, i.e. fever, cough, diarrhea, difficult breathing, ear ache and sore throat occurred at frequencies of 15.6, 8.3, 5.7, 2.0, 1.7 and 0.4 episodes respectively, per child per year. Cough, difficult breathing, common cold and ear ache caused about 50% of all episodes of illness. The majority (61%) of all illness episodes were treated in dispensaries, health centres or hospitals. 18.9% were attended by Village Health Workers (VHWs), 14.5% received treatment at home and 3.5% were seen by traditional healers. The use of VHWs was associated with a reduction of home-treatment and reliance on traditional healers for the care of perceived illness. VHW's monthly reports revealed malaria to be the number one health problem both among children and adults, responsible for about 25% of all attendances.

To investigate the causes and clinical characteristics of acute pharyngitis among school-aged children (4 to 18 years), we obtained throat cultures for respiratory viruses, Mycoplasma pneumoniae, group A streptococcus, and Chlamydia trachomatis from 320 patients with sore throat and 308 controls without respiratory complaints. The study was conducted from January to April 1985 in a private pediatric practice in central New York State. Sixty percent of the patients and 26% of the control subjects had positive cultures for at least one organism. Forty percent of patients had positive cultures for group A streptococcus, compared with 11.9% of the controls. Fifty (16%) patients had positive viral cultures, compared with eight (2.6%) controls; the predominant viral isolate was influenza A Philippines. Patients infected with influenza A were significantly more likely to complain of cough and hoarseness, and were less likely to have pharyngeal exudate or tender cervical adenopathy, than were patients who had positive cultures for group A streptococcus. Although 49 (15.8%) patients with acute pharyngitis had cultures positive for M. pneumoniae, 53 (17.6%) asymptomatic controls were also had M. pneumoniae-positive cultures. Thus detection of M. pneumoniae in the throat of school-aged children with pharyngitis may not be sufficient to establish a diagnosis of disease caused by this organism. C. trachomatis was not isolated from any patient or control.

In a broom manufacturing factory the authors performed microclimatic measurements, measurements of sulfur dioxide concentration and dust content. Workers (n = 190) were polled regarding discomforts characteristic of sulfur dioxide effects. Sulfates were determined in urine of 56 subjects, and methemoglobin and sulfhemoglobin were determined in blood. Sulfates were determined in 43 controls and methemoglobin and sulfhemoglobin were determined in 39 controls. Sulfur dioxide concentration in work environment ranged from 17.1 to 149.4 mg/m3 in winter and from 0 to 0.75 mg/m3 in summer. The exposed workers complained most often of coughing (94.2%), dyspnea (91.0%), burning in nose, eyes and throat (from 74.7 to 83.7%), substernal pain (75.3%), sore throat (74.7%), tearing (64.7%), etc. Sulfate concentrations were found to be statistically significantly higher (P less than 0.01) in urine of workers exposed to sulfur dioxide than in the controls. Methemoglobin concentrations were also significantly higher in blood of the exposed workers, whereas no difference was found in concentrations of sulfhemoglobin.

We interviewed the parents of 128 asthmatic children about their knowledge and misconceptions of asthma. Two-third or more gave correct responses to questions on aetiology and pathogenesis, pathophysiology, symptomatology, precipitants and outcome of asthma. A control group of parents of 110 children admitted to the hospital with minor surgical complaints performed equally well on the knowledge questions, except for four sub-questions: (1) allergy as an aetiologic factor in asthma (64.5% vs 83.6%, P = 0.002), (2) constriction of airways as a bodily change during an asthmatic attack (75.4% vs 91.3%, P = 0.004), (3) cough as a symptom of asthma (82.7% vs 99.2%, P less than 0.001) and (4) change in weather (81.0% vs 95.5%, P = 0.002) or cold weather (60.9% vs 74.2%, P = 0.015) as triggers of asthma. However, a significant minority of both groups of parents were found to harbour misconceptions about asthma. Between 10-20% believed that poor care, inappropriate diet during pregnancy or premature birth can predispose a child to asthma. About one-third believed that bodily changes during an asthmatic attack include loss of control or paralysis of chest muscles, infection of lungs and compression of the lungs by the stomach. Also about one-third believed that swallowing a hard object or touching a poisonous plant can set off an asthmatic attack. Some 10% believed that diarrhoea is a symptom of asthma, while 50% regarded sore throat as a symptom. Up to 40% believed in restriction of outdoor play by asthmatic children.(ABSTRACT TRUNCATED AT 250 WORDS)

The relation of respiratory symptoms, pulmonary function, and abnormalities of chest radiographs to estimated exposures of borax dust has been investigated in a cross sectional study of 629 actively employed borax workers. Ninety three per cent of the eligible workers participated in the study and exposures ranged from 1.1 mg/m3 to 14.6 mg/m3. Symptoms of acute respiratory irritation such as dryness of the mouth, nose, or throat, dry cough, nose bleeds, sore throat, productive cough, shortness of breath, and chest tightness were related to exposures of 4.0 mg/m3 or more, and were infrequent at exposures of 1.1 mg/m3. Symptoms of persistent respiratory irritation meeting the definition of chronic simple bronchitis were related to exposure among non-smokers. Decrements in the FEV1 as a percentage of predicted were seen among smokers who had heavy cumulative borax exposures (greater than or equal to 80 mg/m3 years) but were not seen among less exposed smokers or among non-smokers. Radiographic abnormalities were uncommon and were not related to dust exposure. Borax dust appears to act as a simple respiratory irritant and perhaps causes small changes in the FEV1 among smokers who are heavily exposed.

Killed and live influenza virus vaccines were given to asthmatics and healthy subjects to investigate symptoms and alterations in their respiratory performance after vaccination. Polyvalent killed influenza virus vaccine was given to 16 asthmatics and live attenuated influenza virus vaccine to 23 asthmatics and 21 healthy subjects. Fourteen of the 16 asthmatics vaccinated with the killed vaccine displayed a significant rise in serum antibody level as measured by a single radial haemolysis in gel (SRH test). 11 of the 23 asthmatics and 14 of the 21 healthy subjects vaccinated with the live attenuated vaccine displayed a significant rise in the SRH test. Among the subjects with no measurable initial antibodies and with a significant rise in the SRH test, one asthmatic vaccinated with the killed vaccine experienced symptoms of common cold with fever and dyspnoea 1 week after vaccination. Three asthmatics and four healthy subjects vaccinated with live attenuated vaccine experienced mild symptoms, mainly rhinorrhoea, cough and sore throat 2 to 3 days after vaccination. No alterations in specific airway conductance in asthmatics or in healthy subjects were observed. We conclude that both killed and live attenuated influenza virus vaccines are tolerated well by asthmatics and appear to be safe for asthma patients.

Use of the antineoplastic agents frequently causes myelosuppression and neutropenia. Neutropenic patients often fail to manifest the usual signs and symptoms of infection; they are unable to mount an adequate inflammatory response and infection disseminates rapidly. There is a direct correlation between the degree of granulocytopenia and the incidence and severity of infections. During the period of granulocytopenia (the vulnerable period) the risk of infection is high. While safeguarding the patient throughout the entire period of hospitalization, nurses should be more vigilant during this time. They must be alert to subtle signs of infection and the patient should be monitored closely for increased temperature (greater than or equal to 101 degrees F), mouth sores, sore throat, cough, congestion, or dysuria. The patient undergoing chemotherapy faces many threats to survival. This patient also offers an extraordinary challenge to nursing practitioners because good care may significantly improve the patient's quality and length of life.

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.
