Pharyngitis, bronchitis, and pneumonia represent the most common respiratory tract infections. With a view to establishing effective management strategies, the origins of these illnesses and the diagnostic techniques that have been developed to discover them are reviewed. Therapeutic regimens with documented efficacy are outlined with emphasis on specific rather than empiric treatment. Although many respiratory tract pathogens remain exquisitely sensitive to penicillin, the emergence of resistant strains underscores the need for safe and effective alternative therapies.

A total of 560 patients were treated in two double-blind, randomized multicenter studies to compare the safety and efficacy of cefixime (400 mg administered once daily) and amoxicillin (250 or 500 mg administered three times daily) for the treatment of bacterial respiratory tract infections. Eighty percent of the 244 patients treated in the lower respiratory tract infections (LRTI) study had acute bronchitis. Streptococcus pneumoniae (13 percent), Haemophilus influenzae (28 percent), and Escherichia coli (10 percent) were the pathogens most frequently isolated from sputum in these patients. Among evaluable patients with positive bacterial culture results at baseline, a favorable clinical response (cured or improved) was obtained in 100 percent of the cefixime-treated patients (22 of 22) and in 96 percent of the amoxicillin-treated patients (23 of 24). Bacteriologic eradication rates were 100 percent and 83 percent for cefixime and amoxicillin, respectively. In the upper respiratory tract infections (URTI) study, 316 patients with pharyngitis (80 percent) or tonsillitis (14 percent) were treated. Group A, beta-hemolytic Streptococcus (69 percent) and H. influenzae (8 percent) were the pathogens most frequently isolated from the throat culture specimens of these patients. Favorable clinical results were obtained in 99 percent of the evaluable cefixime-treated group (n = 73) and in 98 percent of the amoxicillin-treated group (n = 66). The bacteriologic eradication rates were 93 percent and 100 percent, respectively. The adverse experiences reported during both studies were similar in nature and frequency to those reported for other beta-lactam antibiotics with the exception of a higher incidence of altered bowel movement (diarrhea and stool changes) with both drugs. These episodes usually resolved without remedial medication when the treatment was withdrawn. No significant adverse laboratory findings were observed. Results of these trials demonstrate that cefixime at a dosage of 400 mg once daily is an effective and safe oral antibiotic for the treatment of acute respiratory tract infections.

A 35-year-old woman developed pharyngitis with high fever and painful joint swellings. A severe cholestatic hepatitis occurred 40 days later with a rise of bilirubin to 32 mg/dl. "Nuclear dot" antibodies were demonstrated in the immunofluorescence test on cell cultures, confirming a diagnosis of primary biliary cirrhosis which had followed an atypical course. After nine days of cefotaxime administration, commenced because of persistent fever of 40 degrees C, an agranulocytosis was demonstrated, which regressed within a week of discontinuing the drug. The allergic genesis of the agranulocytosis was proven by repeated lymphocyte stimulation tests in the presence of cefotaxime. The autoimmune hepatitis was probably a predisposing factor in the genesis of the allergically induced agranulocytosis.

Cyclic neutropenia is a benign, hematologic disorder characterized by recurrent episodes of severe neutropenia at 21 day intervals. There are associated cyclical variations in other blood cells. Patients with this disease have malaise, stomatitis, cervical lymphadenopathy and fever during the recurrent neutropenic periods. The exact cause of cyclic neutropenia is unknown. About one third of human cases appear to be inherited in an autosomal dominant pattern. In the other cases, the disease appears to arise spontaneously with symptoms usually beginning in infancy or early childhood. In adult patients, the disease may be acquired and occur in association with a clonal proliferation of large granular lymphocytes. Clinical studies in man and investigations in grey collie dogs, which have a very similar disease, strongly suggest that cyclic neutropenia is due to an abnormality in the regulation of early hematopoietic precursor cells. Therapy for cyclic neutropenia involves local and symptomatic therapy for the recurrent mouth ulcers and pharyngitis, and antibiotics for episodes of sinusitis, pneumonia, peritonitis, or bacteremia. Therapy with glucocorticosteroids, androgens, and plasmapheresis has been efficacious in a few adult patients, but no therapy has been proven to alter the cycling of blood counts in children. Despite their repetitive illnesses, patients with cyclic neutropenia grow and develop normally. With the help of attentive physicians and dentists, their quality of life and life expectancy are good. Current research on hematopoietic growth factors offers promise of new approaches to therapy.

To determine if a single daily dose of cefadroxil would be effective in the treatment of group A beta-hemolytic streptococcal (GABHS) pharyngitis, 196 patients with GABHS pharyngitis were randomly assigned to receive either penicillin V 250 mg three times daily or cefadroxil 30 mg/kg once daily, for 10 days. Outcome was measured by the ability to isolate GABHS from the upper respiratory tract 18 to 24 hours after the onset of therapy, the impact on the clinical course, and the bacteriologic treatment failure rate. There was no significant difference in the number of patients in the cefadroxil and penicillin V treatment groups with throat cultures positive for GABHS at the 18 to 24-hour follow-up visit (0% and 2%, respectively), and the clinical responses of the patients in the two treatment groups were similar. Of the 99 patients in the three times daily penicillin V group, six (6%) had strains of GABHS isolated on one of the follow-up cultures that were identical to the strains isolated from their initial throat cultures and were considered to have bacteriologic treatment failures. Of the 96 patients in the once daily cefadroxil group, two (2%) were considered to have bacteriologic treatment failures. A single daily dose of cefadroxil appears to be as effective in the treatment of GABHS pharyngitis in this population as penicillin V given three times daily.

Mother, father (26 y.o.) and their only child (5 y.o.) developed nonproductive cough, fever (39.5 to 40.4 degrees C) and bilateral pulmonary infiltrates within three weeks. In addition the mother developed a small left pleural effusion and a pericardial effusion, a relative bradycardia, a pruritic vesicular exanthem of the extremities and the trunk, an erythema nodosum and arthritis of the tarsal joints. The father's coulter counter red blood count was distorted by microagglutination at room temperature (hemoglobin 13.2 gr/dl; erythrocytes 1,91 X 10(6) mm-3 and MCH 69.1 pg; MCV 120 fl and hematocrit 23.8%) but not at 37 degrees C (13.2; 4.15 and 31.8; 92 and 39.3, respectively). In the daughter myringitis, pharyngitis, cervical lymphadenopathy and splenomegaly were observed. Cold agglutinins and serologic evidence for mycoplasma pneumoniae infection were demonstrable in all three. Treatment with Tetracycline (parents) and Erythromycin (child) was effective.

Three horses were examined for ulcerative pharyngitis, which had been unresponsive to treatment. Biopsy specimens of the pharyngeal lesions were characterized histologically by a mixed population of lymphocytes and histiocytes, suggesting chronic inflammation. Only when biopsy specimens of regional lymph nodes revealed this cell population disrupting the lymph node architecture was the diagnosis of malignant lymphoma made.

Early diagnosis of acute human immunodeficiency virus (HIV) infection is difficult because patients may be seronegative for HIV at the time of presentation. We have used a serum HIV antigen (HIV-Ag) enzyme immunoassay (EIA) to diagnose acute HIV infection in four high-risk patients. The clinical syndrome in these four patients was characterized by fever (four), rash (three), myalgias-arthralgias (three), and pharyngitis (two). All patients had spontaneous resolution of their symptoms within eight to 12 days. Serum HIV antibody, as measured by a commercially available screening EIA and by Western blot analysis, was negative in all patients at time of presentation and all seroconverted on subsequent testing. Human immunodeficiency virus was isolated from two of two patients during the acute illness. Initial serum samples from all four patients were positive for HIV-Ag. Serum samples of three of four patients became negative for HIV-Ag and positive for HIV antibody. These data suggest that serum HIV-Ag detection by EIA may be useful in the diagnosis of the acute syndrome caused by HIV infection.

A group of 146 children with acute rheumatic fever and 256 members from their families, and a group of 125 children with post-streptococcal glomerulonephritis and 199 family members, together with a group of 145 children with non-complicated group A streptococcal pharyngitis were examined over a period of three years. The purpose of the study was to explore the concurrent association and distribution of group A streptococcal serotypes among the three groups. Strains isolated from the children with non-complicated group A streptococcal pharyngitis represented the prevalent strains of group streptococci in the childhood community during the period of study. Rheumatic fever was encountered in a non epidemic situation. As expected, the recovery of group A streptococci was low. The strains however belonged mainly to two patterns, namely type M1 and M non-typable strains. Nephritis was pharyngitis-associated and occured also sporadically throughout the year. Types M12 and 49 accounted for the majority of the isolates. Type M12 accounted for 34.4% of the group A isolates from family members of children with nephritis and was totally absent in family members of children with rheumatic fever (p less than 0.001). The T pattern 8/25/Imp. 19 accounted for 40% of the group A isolates from family members of rheumatic patients compared to 3.3% from family members of nephritis patients (p less than 0.005). Data from this study show that the group A streptococcal serotypes, concurrently isolated from children with acute rheumatic fever and their families are disparately different from those of children with pharyngitis-associated glomerulonephritis and their families in the same population. These findings support the concept of "nephritogenicity" and "rheumatogenicity" and indicated the important role of the biological characteristics of the streptococcal serotypes in the aetiology of acute rheumatic fever and acute poststreptococcal glomerulonephritis.

A virus, identified as Tettnang virus, was isolated from the cerebrospinal fluid (CSF) of an 18 months old child with pharyngitis accompanied by an encephalitic reaction. The isolation of virus was followed by seroconversion. The aetiological role of the virus in the given disease is discussed.
