Burkitt lymphoma of the ovaries mimicking sepsis: a case report and review of the literature.

BACKGROUND: It is not unusual for systemic diseases to mimic sepsis and, in any case, the clinician should thoroughly investigate this possibility. CASE PRESENTATION: We present the case of a 21-year-old Greek woman who presented to the Intensive Care Unit of our hospital with severe septic shock - multiple organ failure as a result of a suspected gynecological infection of the ovaries. An immediate improvement of her clinical condition in combination with strong clinical suspicion and negative cultures led to the differential diagnosis of diseases other than sepsis. Based on the results of the biopsies that were obtained by research laparotomy, our patient suffered from primary Burkitt ovarian lymphoma. Her clinical condition improved with supportive treatment and chemotherapy. Chemotherapy is the dominant treatment for Burkitt's lymphoma, while surgery or radiotherapy has no place. CONCLUSIONS: All intensivists should be aware of clinical conditions that mimic sepsis as early diagnosis can lead to appropriate therapy and avoid unnecessary diagnostic tests and antibiotic abuse.

Incidence and predictors of new-onset atrial fibrillation in noncardiac intensive care unit patients.

BACKGROUND: Atrial fibrillation (AF) is thought to be a relatively common arrhythmia in the setting of noncardiac intensive care unit (ICU). However, data concerning AF deriving from such populations are scarce. In addition, it is unclear which of the wide spectrum of AF predictors are relevant to the ICU setting. OBJECTIVES: The aim of our study was to evaluate the incidence of new-onset AF and investigate the factors that contribute to its occurrence in ICU patients. METHODS: We prospectively studied all patients admitted to our ICU during a 1-year period. Patients admitted for brief postoperative monitoring and patients with chronic or intermittent AF and AF present upon admission were excluded. A number of conditions incriminated as AF risk factors or "triggers" from demographics, medical history, present disease, and cardiac echocardiography as well as circumstances of AF onset were recorded. RESULTS: The study population consisted of 133 patients (90 males). Atrial fibrillation was observed in 15% of them. Age older than 65 years (P=.001), arterial hypertension (P=.03), systemic inflammatory response syndrome (P<.001), sepsis (P=.001), left atrial dilatation (P=.01), and diastolic dysfunction (P=.04) were significantly associated with the occurrence of AF. By multivariate analysis, it was demonstrated that only older than 65 years (odds ratio, 7.0; 95% confidence interval, 2.0-24.6; P=.003) and sepsis (odds ratio, 6.5; 95% confidence interval, 2.0-21.1; P=.002) independently predict new-onset AF. Patients manifesting AF were frequently hypovolemic (30%) and had electrolyte disorders (40%) as well as elevated and rising serum C-reactive protein (70%). CONCLUSION: A significant fraction of ICU patients manifest AF. The predictors of interest for the ICU patients might be considerably different than those of the general population and other subgroups with systemic inflammation possibly having a pivotal role.
