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.

An outbreak of influenza virus type B infection occurred in Philadelphia from December, 1985, to April, 1986. During this epidemic 24 patients were admitted to Children's Hospital from whom influenza B was isolated from routine respiratory viral cultures. All were younger than 3 years of age. Clinical findings included fever (greater than or equal to 38 degrees C) (88%), rhinorrhea (62.6%), cough (50%), otitis (50%), rhonchi (42%), vomiting (38%), diarrhea (33%), rales (21%), pharyngitis (13%) and croup (4%). Remarkably 75% of the patients had underlying diseases which may have contributed to the severity of the infection. Nine (41%) patients had pneumonia. Two patients died of respiratory failure caused by overwhelming influenza B virus infection. Patients admitted to the hospital with respiratory and underlying diseases should have viral respiratory cultures which include influenza B.

Recently many refugees from Sri Lanka have arrived in Europe. The purpose of the present investigation was to analyze the subjective complaints and diagnoses in these refugees. One hundred refugees (97 males, 3 females, age 19 to 42 years) were investigated. The most common reasons for consulting a general internist were cough (23%), general pain in soft tissue and joints (21%), disorders of the gastrointestinal tract (19%) and ear or throat complaints (15%). In 43% of the patients no diagnosis could be established. 58 patients were investigated for parasites in stool: 57% of these patients had hookworms, 12% non-pathogenic protozoon, 9% Entamoeba histolytica cysts, and 2% Giardia lamblia. In 12% of the patients the diagnosis was tonsillitis or pharyngitis, in 7% bronchitis, pneumonia or asthma and in 5% arterial hypertension. Various other diagnoses were established in 48 patients. With the exception of the high frequency of intestinal parasites, complaints and diagnoses in these refugees were the same as in a comparable European population.

This paper describes the results of a study of live attenuated measles vaccines (one in a series of WHO-sponsored field trials) carried out in children 6-33 months old at an orphanage in Quebec City. The Enders Edmonston B vaccine alone and the same vaccine administered with gamma-globulin were compared with the Schwarz further-attenuated vaccine. The over-all seroconversion rates were found to be 96.9%, 98.1% and 98.8% respectively. Severe clinical reactions, except for high fever, were not observed in any of the groups. Rectal temperatures over 103 degrees F (39.5 degrees C) were noted in 16.2% of the children given Schwarz vaccine, in 59.2% of the children receiving the Enders Edmonston B vaccine alone and in 27.8% of the children inoculated with the Enders Edmonston B vaccine plus gamma-globulin. The high incidence of mild pharyngitis following inoculation of these vaccines was not observed in the group of children who had received vaccine plus gamma-globulin. No significant differences were noted in the frequency of other symptoms, such as cough, coryza, conjunctivitis and diarrhoea, between vaccinated and control groups.

Acute respiratory tract infections represent the major cause of morbidity in younger age groups. Most of these infections involve the upper respiratory tract. The frequency of respiratory tract infections vary not only with age, but also with season of the year and the epidemiological situation. Surveys of the incidence and aetiology of these infections must therefore cover large populations during relatively long periods of time. In the developed countries, the mortality in respiratory tract infections in patients below the age of 60 years is low, while it increases markedly in elderly patients, mainly due to involvement of the lower respiratory tract. Aetiologically, viral infections dominate but bacterial pathogens often cause pharyngitis/tonsillitis, otitis media and sinusitis. In longstanding cough in children, Branhamella catarrhalis has been found to be a pathogen of probably high significance. Other factors increasing the clinical importance of colonisation of the upper respiratory tract with potentially pathogenic bacterial species, are various immune defects, especially reduced IgA production, and granulocytopenia. In the latter case, Gram-negative bacteria seem to be more pathogenic than Gram-positive ones. The clinical differentiation between viral and bacterial upper respiratory tract infections is difficult and sometimes not possible. However, based on the knowledge that acute tracheitis, laryngitis and common cold are normally caused by viral agents, it seems reasonable not to use antibiotics for those patients.

In a clinical and bacteriological study of 42 patients with acute tonsillo-pharyngitis or chronic tonsillo-pharyngitis with acute exacerbation, patients were allocated at random to receive either a 3-day course of spiramycin or a 5-day course of erythromycin, both antibiotics being given in a dosage of 500 mg 3-times daily. The median time to disappearance of patient complaints such as fever, difficulty in swallowing, sore throat, cough and mucus was 3 days in each group and there was a significant reduction from pre-treatment to normal levels in total white cell count and erythrocyte sedimentation rate after treatment. Although more patients were considered to have shown a good clinical response to spiramycin, the difference was not statistically significant. From a bacteriological point of view, however, treatment with the regimen used was considered a failure in all cases in that neither antibiotic completely eradicated the pathogens identified at the start of treatment even though, with 3 exceptions, all of the micro-organisms were shown to be sensitive to the antibiotics before and after treatment. Few side-effects were reported in either group.

Selected events in rhinovirus infection of the normal human airway can be regarded as occurring sequentially. Initial steps in rhinovirus pathogenesis are believed to include viral entry into the nose, mucociliary transport of virus to the posterior pharynx, and initiation of infection in ciliated and non-ciliated epithelial cells of the upper airway. Viral replication peaks on average within 48 h of initiation of infection and persists for up to 3 wk. Infection is followed by activation of several inflammatory mechanisms, which may include release or generation of interleukins, bradykinins, prostaglandins, and possibly histamine and stimulation of parasympathetic reflexes. Pathophysiologic processes are initiated, which include vasodilatation of nasal blood vessels, transudation of plasma, glandular secretion, and stimulation of nerve fibers, causing pain and triggering sneeze and cough reflexes. The resultant clinical illness is a rhinosinusitis, pharyngitis, and bronchitis, which, on average, lasts 1 wk.

Patients with asthma-like symptoms may not have asthma but obstruction of the extrathoracic airway (EA). To evaluate if dysfunction of the EA causes asthma-like symptoms, we assessed bronchial and EA responsiveness to inhaled histamine in 441 patients who presented with at least one of three key symptoms--cough, wheeze, dyspnoea--but had neither documented asthma nor bronchial obstruction. The histamine concentrations causing a 20% fall in forced expiratory volume in 1 s (PC20FEV1) and a 25% fall in maximal mid-inspiratory flow (PC25MIF50) were used as respective thresholds of bronchial and EA responsiveness. Values 8 mg/mL or less indicated bronchial (B-HR) or EA hyper-responsiveness (EA-HR). The influence of concurrent upper respiratory tract diseases, such as post-nasal drip (PND), pharyngitis, laryngitis and sinusitis, was also assessed. We found four response patterns to the histamine challenge: EA-HR in 26.5% of the patients, B-HR in 11.1%, combined EA-HR and B-HR in 40.6%, and no-HR in 21.8%. Cough was reported by 79% of the patients, wheeze by 53%, and dyspnoea by 40%. Patients with cough as the sole presenting symptom (34.2%), as compared with those with wheeze and/or dyspnoea (20%), had significantly greater probability of having EA-HR (OR 5.35, 95% CI 3.25-8.82) and lower probability of having B-HR (OR 0.45, CI 0.28-0.70); patients with cough plus wheeze and/or dyspnoea (45.8%) had significantly greater probability of having both EA-HR and B-HR than either those with cough alone (OR 2.48, CI 1.49-4.13), or those with wheeze and/or dyspnoea but not cough (OR 1.74, CI 1.36-2.22). EA-HR alone or combined with B-HR was strongly associated with EA diseases, particularly pharyngitis and PND. Cough was significantly associated with PND, either when it was the sole symptom (OR 2.16, CI 1.14-4.09) or when it was combined with wheeze and/or dyspnoea (OR 3.53, CI 1.97-6.33). Our results suggest that extrathoracic airway dysfunction may account for asthma-like symptoms, particularly chronic cough. This abnormality seems to be sustained by chronic diseases of the upper respiratory tract.

Adenoviral pneumonia, while most common in infancy and young childhood, is rare in school childhood. Here, we report one case, a 13 years old otherwise healthy girl, suffered from fulminating pneumonia caused by adenovirus infection. She had dry cough, pharyngitis, lethargy, myalgia and fever in the beginning. Four days later, the patient became tachypneic, dyspneic and drowsy, and developed hypoxemia and diffuse bilateral infiltrates on chest radiographs. The laboratory data revealed elevated SGOT, CPK and LDH. Adenovirus was isolated from patient's endotracheal suction tube tips. Fortunately, weaning from mechanical ventilation was accomplished on the fifth day of hospitalization, despite of the high fatality rate of adenoviral pneumonia in this age group. The clinical characteristics and therapeutic management of our case are discussed and literatures reviewed.

We reviewed the thirty cases of cytomegalovirus infections with occurred in previously healthy patients, hospitalised for fever from 1981 to 1992. Pregnant women, transplant recipients, HIV infected persons and all immunocompromised subjects were excluded. We observed 34 cases (18 women, 16 men) whose mean age was 34 years (17 to 79). Fever appeared progressively (73%), persisted more than 15 days (87%) and was well tolerated. The main functional symptoms were headaches, myalgia (53%), profuse sweat (50%), abdominal pain, diarrhea, recent loss of weight, dry cough (51%). Splenomegaly was present in 24% of the cases. Chest X ray was always normal. Differential blood count was always inverse and an authentic mononucleosis syndrome was present in 91%: it appeared mainly 13 days after onset of symptoms. Hepatic abnormalities were nearly constant, especially cytolytic (97%) (transaminases three or four times upper the normal limit) but also cholestatic (62%). Thrombopenia has been noticed once (48,000/mm3). Serological diagnosis was confirmed with Elisa test (anti CMV Ig M: 30 cases) or complement fixation test (seroconversion: one, significant increase of the titers: two). CMV viremia, studied in seven patients, was positive in three. Spontaneous or treated (NSAI in 30%) outcome was nearly always favourable (97%). Two patients presented severe complications: meningo encephalitis and spleen rupture. CMV infection in previously healthy patients has to be suspected, without waiting for the mononucleosis syndrome, in view of a prolonged, well tolerated febrile illness, without pharyngitis, associated with hyperlymphocytosis and mild cytolysis. A careful follow-up is needed to detect the rare but severe complications.
