STUDY OBJECTIVES: To characterize the early cytokine response of patients presenting to the emergency department with necrotizing fasciitis (NF) and to determine whether serum cytokine levels and white blood cell (WBC) counts may be useful in distinguishing NF from other severe soft-tissue infections. METHODS: White blood cell counts and cytokine levels (IL-1beta, IL-1Ra, IL-6, IL-8, IL-18, and IFN-gamma) were measured in patients presenting to the emergency department with severe soft-tissue infections and high suspicion of NF. Necrotizing fasciitis was confirmed intraoperatively and by surgical pathology. Cytokines were measured via the liquid-phase electrochemiluminescence method. RESULTS: Thirty-five patients were enrolled, 18 were diagnosed with NF, and 17 were diagnosed with cellulitis and/or abscess (CAB). On admission, patients with NF had significantly higher WBC counts and lower levels of interleukin 1beta (IL-1beta) compared with patients with CAB. There were no statistically significant differences in the levels of the other cytokines between the 2 groups. CONCLUSION: Patients with NF have higher WBC counts and lower IL-1beta levels compared with patients with CAB.
OBJECTIVE: Reactive thrombocytosis can be found in patients with different types of infections, including upper urinary tract infection (UTI). In this study, we determined whether thrombocytosis in patients with upper UTI is a random phenomenon or is related to complications associated with the UTI. METHODS: We reviewed the charts of patients admitted to the urology department with a diagnosis of upper UTI and thrombocytosis (platelet count >500 x 10(9)/L) in the years 1991 to 2003 (study group). Patients admitted to the urology department in the year 2003 with a diagnosis of upper UTI without thrombocytosis served as the control group. RESULTS: The study group consisted of 83 patients admitted to the urology department with a diagnosis of upper UTI and thrombocytosis (mean platelet count, 593 x 10(9)/L; SD, 88; range, 501-949). The control group consisted of 99 patients. An obstructed kidney was found in 54 patients (65%) of the study group and in 18 patients (18%) of the control group (P < .00001). Perinephric abscess was found in 7 patients (8%) in the study group compared with none in the control group (P < .003). The positive predictive value of thrombocytosis for kidney obstruction or abscess in patients with upper UTI was 71%. Nephrectomy of a nonfunctioning infected kidney was required in 6 patients of the study group (7%) and 2 of the control group (P = .14). In 26 patients (31%) of the study group, the finding of thrombocytosis preceded the diagnosis of the complication (by a median period of 3 days). In these patients, thrombocytosis was essentially an early marker for the complication. CONCLUSIONS: Thrombocytosis in a patient with upper UTI is not a random phenomenon. It is a marker of kidney obstruction or perinephric abscess. The finding of thrombocytosis in a patient with upper UTI should alert the attending physician to actively search for these complications. Cross-sectional imaging study (abdominal ultrasonography or computed tomography) should be performed.
PURPOSE: The purpose of this preliminary retrospective study was to review the demographics and outcome of patients with a variety of facial fractures that were stabilized with PL bone plates and screws. MATERIALS AND METHODS: The records of 295 consecutive patients with facial fractures treated by open reduction and internal fixation, performed by the author from 2001 through 2004, were retrospectively reviewed. Patients were selected to receive biodegradable fixation on the basis of mechanism of injury, the degree of bony displacement demonstrated on clinical and radiographic examination, patient age, and fracture pattern or location. Outcome measures such as infection, non-union, and mal-union were identified and subjectively assessed. Descriptive statistics were recorded and analyzed. RESULTS: Two hundred eighty-one patients met the criteria for inclusion in the study with follow-up of 3 weeks to 3 years. Fifty-nine (21%) patients were identified as having received biodegradable plates and screws. All patients eventually went on to satisfactory healing with favorable restoration of form and function. Complications occurred in 16 patients overall (6%). Of these, 2 patients were treated with resorbable plates and screws; 1 patient with a zygomatico-maxillary complex fracture developed a sterile abscess that presented 1 year postoperatively and responded to local measures. Another patient with a Le Fort I fracture developed an anterior open bite necessitating Le Fort I osteotomy for correction. CONCLUSIONS: Favorable healing can be observed through the use of biodegradable PL plates and screws to stabilize selected midface fractures in patients of all ages, as well as mandible fractures in early childhood.
