Periorbital cellulitis is a commonly occurring infectious process limited to the eyelids in the preseptal region. It occurs with greater frequency in the pediatric age group. It is important to distinguish this disease from orbital cellulitis, a potentially lethal infectious process involving the contents of the orbit. A retrospective study of clinical and laboratory data from 137 cases with orbital and periorbital cellulitis was performed. Periorbital cellulitis was documented in 98 cases (71%) in contrast to orbital cellulitis, which was noted in 39 (28%) patients. Sinusitis was the most frequently encountered predisposing factor for the development of periorbital cellulitis occurring in 29 patients. All patients with a diagnosis of periorbital cellulitis were hospitalized and received antibiotics, the majority (95%) receiving intravenous therapy. Hemophilus influenzae was the most frequently isolated pathogenic organism. It was necessary to operate on eight patients. Six patients underwent incision and drainage of an eyelid or periorbital abscess. A distinction between periorbital and orbital cellulitis is clarified. The separation of these entities on the basis of physical examination and radiographic studies is stressed.

Acute sphenoid sinusitis is an uncommon disease with a significant morbidity. This paper reviews 14 patients presenting with acute sphenoid sinusitis between 1978 and 1987. Fifty-seven percent of patients had signs of neurological or ophthalmological complications, and 29% were left with permanent disabilities. Delay in diagnosis and treatment resulted in a morbidity of 80%. The organism most commonly cultured was Staphylococcus aureus, followed by Streptococcus pneumoniae. Haemophilus influenza, and other streptococci. While a trial of medical therapy for 24 hours is warranted in uncomplicated cases, we recommend surgical drainage of the sinus if medical therapy fails, and for all patients with complications.

The clinical and diagnostic features of 29 adult patients with H. influenzae septic arthritis are reviewed. Twelve men and 17 women ranging in age from 22 to 82 years developed the infection. H. influenzae septic arthritis is an acute, febrile disease with a mean duration of symptoms before diagnosis of 4 days. Fifteen patients had monoarticular arthritis, 6 with an infected knee. Polyarticular involvement, with a range of 2 to 9 joints, was diagnosed in 14 patients. Nineteen patients had concurrent extraarticular sites of infection, including meningitis, pneumonia, pharyngitis, sinusitis, conjunctivitis, and cellulitis. Twenty-two of 29 patients had predisposing factors for infection, including ethanolism, trauma, rheumatoid arthritis, systemic lupus erythematosus, diabetes mellitus, splenectomy, multiple myeloma, lymphoma, gout, and acquired common variable hypogammaglobulinemia. Characteristic synovial fluid findings included purulent, greenish fluid, elevated WBC count, and gram-negative pleomorphic microorganisms. Treatment for these patients included antibiotic therapy, most often ampicillin and chloramphenicol, and joint drainage by repeated arthrocentesis or arthrotomy. A favorable outcome was reported in 25 of 29 patients. Hemophilus influenzae septic arthritis should be suspected in adults who are immunocompromised and have a concurrent extraarticular source of infection.

An average of 1.4% of the more than 30,000 participants in a treatment study were diagnosed as having acute sinusitis. 62% of all cases of sinusitis arose in patients aged between 15 and 44 years. Treatment with antibiotics is indicated in purulent sinusitis whilst non-purulent sinusitis is treated either with local or systemic antiphlogistic agents. The secondary bacterial infection is usually caused by Haemophilus influenzae, Streptococcus pneumoniae and anaerobic bacteria. In Scandinavia these probably account for 90% of the purulent sinusitis cases whilst Branhamella catarrhalis is responsible for the remaining 10%. Penicillin V is the agent of choice in acute sinusitis. Cefaclor is preferable in combatting H. influenzae. In a double blind study comparing doxycycline to cefaclor in the management of acute sinusitis (108 patients with cefaclor, 105 patients with doxycycline, no difference emerged between the two groups in the subjective assessment of the treatment results. Objective evaluation recorded excellent results for 88% and 83% of the patients in the cefaclor and doxycycline groups, respectively. Side-effects were noted by 7% of the cefaclor and by 13% of the doxycycline patients. The difference between the incidence of side-effects was not statistically significant. Taking into account the treatment results, the side-effects and ecological aspects, cefaclor is second only to penicillin as the agent of choice in suspected or confirmed purulent sinusitis (e. g. in presence of penicillin allergies or failure of the infection to respond to penicillin V).

Cyclacillin, a new aminosalicylic semisynthetic penicillin, was compared with amoxicillin for the therapy of acute bacterial maxillary sinusitis in 80 patients (ages, 12 to 70 years) in a prospective, double-blind, randomized clinical trial. Direct sinus aspirations for quantitative culture were done for all patients before and after 10 days of therapy. Both drugs were administered at a dosage of 500 mg orally three times daily. Among culture-positive patients, clinical cure was achieved in 23 of 26 patients and 25 of 27 patients treated with cyclacillin and amoxicillin, respectively, for an overall cure rate of 91%. Bacteriologic failure occurred in 9% (4 of 44 patients); 3 of the 4 failures were in the cyclacillin group. There was no correlation between clinical or bacteriologic cure and the results of sinus transillumination (clear, dark) at follow-up. Initial direct sinus aspirates were positive in 57 of 80 cases (70%): 25 (44%) of these were the result of Streptococcus pneumoniae and 23 (40%) were the result of Haemophilus influenzae. All of these isolates were susceptible (MIC, less than or equal to 0.5 microgram/ml) to both study drugs; no ampicillin-resistant H. influenzae was recovered. On day 10 of therapy, mean concentrations of both drugs in serum were 2.5 to 2.7 micrograms/ml, but no antibiotic was detectable in 20 of 21 simultaneous sinus aspirates. Adverse effects (rash, diarrhea) were infrequent and similar in both groups. Cyclacillin appears equivalent to amoxicillin in the therapy of acute maxillary sinusitis.

An in vitro comparison of the activities of 13 oral antimicrobial agents against clinical isolates of bacteria commonly responsible for causing upper respiratory tract infections was performed. With regard to Haemophilus influenzae, beta-lactamase-negative strains were susceptible to amoxycillin, augmentin, cefaclor, erythromycin, trimethoprim, cotrimoxazole and tetracycline, with CL 284,635 being the most active agent. With the exception of amoxycillin these drugs were also active against beta-lactamase-producing strains. CL 284,635 was also very active against Branhamella catarrhalis isolates, including beta-lactamase-producing strains, but was less active against the Gram-positive bacteria tested. Cefadroxil, cephradine and cephalexin were mainly active against Gram-positive pathogens. Based on minimum inhibitory concentration determinations, cefaclor, augmentin and co-trimoxazole would be appropriate drugs for the treatment of those cases of otitis media and sinusitis where H. influenzae and Streptococcus pneumoniae are important pathogens provided they are susceptible to these agents.

Serum immunoglobulins and IgG subclasses were measured in 30 children with recurrent infections. Seven patients had low IgG2 concentrations (less than 3SD below the geometric mean for age). Four of these seven patients had normal concentrations of IgG, IgA and IgM, and thus would have been considered immunologically normal by routine criteria. The seven children with IgG2 deficiency had more severe infections than the 23 children with normal IgG2. Five children had recurrent pneumonia or sinusitis, one had recurrent invasive Haemophilus influenzae type b infections, and one had severe pneumococcal meningitis. Their immunologic abnormalities were heterogeneous. Two children had isolated IgG2 deficiency, two had IgG2-IgG4 deficiency, one had IgG2-IgG4-IgA deficiency, one had IgG2-IgA deficiency, and one had severe IgG1-IgG2 deficiency with abnormal T cell function and thrombocytopenia. Thus IgG2 deficiency occurs frequently among children with recurrent infections, and is associated with a variety of clinical and immunologic abnormalities.

Maxillary and ethmoid sinusitis may occur at any age. Frontal sinus infections first appear in adolescence. The bacteria that cause sinusitis are similar to those associated with otitis media. Streptococcus pneumoniae and Hemophilus influenzae are recovered from 50 to 70 percent of isolates. Anaerobes are also important pathogens in adults. Fungal sinusitis usually occurs only in diabetics or immunosuppressed individuals.

Ceftriaxone is a new semisynthetic cephalosporin with broad-spectrum in vitro activity and an unusually long serum half-life. The clinical efficacy of ceftriaxone was evaluated in 35 infections in 34 patients; 12 of these patients had skin and soft tissue infections, 10 had infections of the urinary tract, 8 had pneumonia, 2 had biliary tract infections, 1 had sinusitis, 1 had diverticulitis, and 1 had a retroperitoneal abscess. Of the 35 infections, 9 were bacteremic. The bacteria isolated included Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pneumoniae, Streptococcus faecalis, other streptococcal species, Escherichia coli, Proteus mirabilis, Klebsiella pneumoniae, Serratia marcescens, Enterobacter cloacae, Haemophilus influenzae, Pseudomonas aeruginosa, Bacteroides fragilis, other Bacteroides species, and anaerobic cocci. Improvement or cure occurred in 32 episodes, for a response rate of 91%. There were three treatment failures in patients with soft tissue infections. No serious drug toxicities were observed. At a dosage regimen of 1 g every 12 h the peak and trough serum antibiotic concentrations were well above the minimal inhibitory concentrations of most pathogens. Our findings suggest that ceftriaxone is a safe and effective antibiotic for therapy of serious bacterial infections.
