Abstract

INTRODUCTION: Campylobacter is an important causative agent of intestinal infections in humans. Bacteremia is detected in less than 1% of patients, mainly in immunocompromised patients and in extreme age groups. Cellulitis is a relatively common manifestation of Campylobacter infection, but concomitant bacteremia is a rare event. Infections of the pacemaker area are caused primarily by staphylococci, followed by fungi, streptococci and Gram-negative rods. To the best of our knowledge, this is the first case report of pacemaker pocket infection and bacteremia caused by Campylobacter fetus.

CASE PRESENTATION:

A 72-year-old Croatian Caucasian man with myelodysplasia, impaired fasting glucose levels and a recently implanted permanent pacemaker was admitted to hospital after six days of fever, development of red swelling of the pacemaker pocket area and worsening of his general condition. No antibiotic therapy was introduced in the outpatient setting. He denied any recent gastrointestinal disturbances. With the exception of an elevated leukocyte count, erythrocyte sedimentation rate, and C reactive protein and blood glucose levels, other laboratory findings were normal. Treatment with vancomycin plus netilmicin was introduced, and a surgical incision with drainage of the pacemaker pocket was performed. The entire pacemaker system was removed and a new one re-implanted after 14 days of antibiotic therapy. Transesophageal echocardiography showed no pathological findings. Three subsequent blood cultures obtained on admission as well as swab culture of the incised pacemaker area revealed Campylobacter fetus; stool and pacemaker lead cultures were negative. According to the microbiological results, antibiotic therapy was changed to ciprofloxacin plus netilmicin  A clinical examination and the results of a laboratory analysis performed after two weeks of therapy were within normal limits.

CONCLUSION:

Myelodysplasia, impaired fasting glucose levels and older age could be contributing factors for the development of bacteremic Campylobacter fetus cellulitis. Emergent surgical and antibiotic treatment are mandatory and provide the optimal outcome for such types of pacemaker pocket infection.

PURPOSE: To describe risk factors predisposing patients to orbital cellulitis and potential complications in patients treated at a tertiary eye care referral center in the Middle East.

DESIGN: Noncomparative, interventional, retrospective case series.

PARTICIPANTS: Patients diagnosed with orbital cellulitis.

METHODS: A 15-year clinical review of patients with a diagnosis of orbital cellulitis referred to King Khaled Eye Specialist Hospital, an accredited (Joint Council on Accreditation of Healthcare Organizations, Washington, DC) tertiary care center in Riyadh, Saudi Arabia, was performed. Only those patients who had clinical signs and symptoms or radiologic evidence suggestive of orbital cellulitis were included in the study.

MAIN OUTCOME MEASURES: Patient demographics, factors predisposing to orbital cellulitis, and resulting complications.

RESULTS: A total of 218 patients (136 male, 82 female) fulfilling the diagnostic criteria for orbital cellulitis were identified. The average age of these patients was 25.7 years (range, 1 month-85 years). On imaging studies, there was evidence of inflammatory or infective changes to orbital structures; orbital abscesses were identified in 116 patients (53%). Sinus disease was the most common predisposing cause in 86 patients (39.4%), followed by trauma in 43 patients (19.7%). All patients received systemic antibiotic treatment before the identification of any responsible organisms. Of the 116 patients with orbital abscess, 101 patients (87%) required drainage. The results of cultures in patients in whom an orbital abscess was drained were positive for 91 patients (90%). The most common microorganisms isolated from the drained abscesses were Staphylococci and Streptococci species. Blood cultures were positive in only 4 patients from whom blood was drawn for cultures. Visual acuity improved in 34 eyes (16.1%) and worsened in 13 eyes (6.2%), including 9 (4.3%) eyes that sustained complete loss of vision, which was attributed to the delay in correct diagnosis and timely intervention (average 28 days vs. 9 days in patients with no loss of vision.

CONCLUSIONS: Untreated sinusitis and prior history of orbital trauma were the 2 major causes of orbital cellulitis in patients referred to a tertiary care eye center in the Middle East. Although rare, severe visual loss still remains a serious complication of delayed detection and intervention in most cases of orbital cellulitis.
