Hematologic and inflammatory parameters for determining severity of odontogenic infections at admission: a retrospective study. BMC Infect Dis 2022; 22:931. [PMID: 36503406 PMCID: PMC9743669 DOI: 10.1186/s12879-022-07934-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Accepted: 12/07/2022] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND Severe odontogenic infections in the head and neck region, especially necrotizing soft tissue infection (NSTI) and deep neck abscess, are potentially fatal due to their delayed diagnosis and treatment. Clinically, it is often difficult to distinguish NSTI and deep neck abscess in its early stage from cellulitis, and the decision to perform contrast-enhanced computed tomography imaging for detection is often a challenge. This retrospective case-control study aimed to examine the utility of routine blood tests as an adjunctive diagnostic tool for NSTI in the head and neck region and deep neck abscesses. METHODS Patients with severe odontogenic infections in the head and neck region that required hospitalization were classified into four groups. At admission, hematologic and inflammatory parameters were calculated according to the blood test results. In addition, a decision tree analysis was performed to detect NSTI and deep neck abscesses. RESULTS There were 271 patients, 45.4% in Group I (cellulitis), 22.5% in Group II (cellulitis with shallow abscess formation), 27.3% in Group III (deep neck abscess), and 4.8% in Group IV (NSTI). All hematologic and inflammatory parameters were higher in Groups III and IV. The Laboratory Risk Indicator for Necrotizing Fasciitis score, with a cut-off value of 6 and C-reactive protein (CRP) + the neutrophil-to-lymphocyte ratio (NLR), with a cut-off of 27, were remarkably useful for the exclusion diagnosis for Group IV. The decision tree analysis showed that the systemic immune-inflammation index (SII) of ≥ 282 or < 282 but with a CRP + NLR of ≥ 25 suggests Group III + IV and the classification accuracy was 89.3%. CONCLUSIONS Hematologic and inflammatory parameters calculated using routine blood tests can be helpful as an adjunctive diagnostic tool in the early diagnosis of potentially fatal odontogenic infections. An SII of ≥ 282 or < 282 but with a CRP + NLR of ≥ 25 can be useful in the decision-making for performing contrast-enhanced computed tomography imaging.

Diagnostic accuracy of contrast-enhanced CT for neck abscesses: A systematic review and meta-analysis of positive predictive value. PLoS One 2022; 17:e0276544. [PMID: 36288374 PMCID: PMC9604924 DOI: 10.1371/journal.pone.0276544] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Accepted: 10/08/2022] [Indexed: 12/02/2022] Open
Abstract
OBJECTIVES To review the diagnostic accuracy of contrast-enhanced computed tomography (CT) in differentiating abscesses from cellulitis in patients with neck infections, using surgical findings as the reference standard. MATERIALS AND METHODS Previous studies in the last 32 years were searched from PubMed and Embase. Because of partial verification bias (only positive abscess findings are usually verified surgically), sensitivity and specificity estimates are unreliable, and we focused on positive predictive value (PPV). For all studies, PPV was calculated as the proportion of true positives out of all positives on imaging. To estimate pooled PPV, we used both the median with an interquartile range and a model-based estimate. For narrative purposes, we reviewed the utility of common morphological CT criteria for abscesses, such as central hypodensity, the size of the collection, bulging, rim enhancement, and presence of air, as well as sensitivity and specificity values reported by the original reports. RESULTS 23 studies were found reporting 1453 patients, 14 studies in children (771 patients), two in adults (137 patients), and seven including all ages (545 patients). PPV ranged from 0.67 to 0.97 in individual studies, had a median of 0.84 (0.79-0.87), and a model-based pooled estimate of 0.83 (95% confidence interval 0.80-0.85). Most morphological CT criteria had considerable overlap between abscesses and cellulitis. CONCLUSIONS The pooled estimate of PPV is 0.83 for diagnosing neck abscesses with CT. False positives may be due to limited soft tissue contrast resolution. Overall, none of the morphological criteria seem to be highly accurate for differentiation between abscess and cellulitis.

[PMID: 35733094 PMCID: PMC9215011 DOI: 10.1186/s12879-022-07545-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2021] [Accepted: 06/16/2022] [Indexed: 02/08/2023] Open
Abstract
Background Cervicofacial space infections are potentially life-threatening, which require accurate diagnosis, early incision, and adequate drainage. The utilization of computed tomography (CT) in cervicofacial space infections has significantly increased for its advantages in the evaluation of abscesses, its availability, and low cost. However, the clinical value of preoperative CT imaging in cervicofacial space infections remains controversial for its poor specificity, radiation exposure, potential complications, and extra cost. We, therefore, investigated whether CT examination should be used as a routine examination in the treatment of patients with cervicofacial space infections. Methods A retrospective study of all patients affected by cervicofacial space infections that received incision and drainage surgery from Jan 2016 to Dec 2020 was performed at West China Hospital of Stomatology at Sichuan University. Patients were divided into two groups: the group with preoperative CT and without preoperative CT. Outcomes, including reoperation rate, missed diagnosis rate, days of symptom relief, length of stay, duration of surgery, and total cost of hospitalization, were analyzed. Results Out of n = 153 patients, 108 patients underwent surgery with preoperative CT and 45 patients without preoperative CT. The reoperation rate in the preoperative CT group (6/108, 5.6%) was significantly lower (P = 0.00) than that in the group without preoperative CT (10/45, 22.2%). Significant reduction of missed diagnosis rate (P = 0.00), days of symptom relief (P = 0.01), length of stay(P = 0.03), and duration of surgery (P = 0.01) were detected in the preoperative CT group. The results demonstrated that the utilization of preoperative CT can reduce the missed diagnosis rate and repeated surgery complications. Conclusions We recommend preoperative CT as a routine examination in cervicofacial space infections.

Abstract
Despite the wide availability of antibiotics and medical care, deep neck infections requiring hospitalization are associated with significant morbidity and mortality. Thus, early recognition and aggressive treatment are key in preventing unfavorable outcomes. We present the case of a patient who rapidly progressed from nonspecific upper respiratory symptoms to obstructive airway loss and death due to a swiftly worsening deep neck infection.

Abstract
PURPOSE To determine whether intensive care unit (ICU) admissions for odontogenic infections have increased during the past decade and whether certain clinical features are associated with a greater rate of ICU admission. MATERIALS AND METHODS The data from patients undergoing surgery for odontogenic infections at the Royal Brisbane and Women's Hospital in the 24 month from January 2003 to December 2004 were compared with those from patients treated from January 2013 to December 2014. A χ2 analysis was used to compare the demographic, admission, and clinical patient data in each cohort. A multiple logistic regression model was used to determine which clinical features were associated with greater rates of ICU admission. RESULTS The rate of ICU admission increased significantly from 7 to 24% during the decade (χ2 = 12.74; P = .000), although the clinical presentation of patients admitted to the ICU was similar in both cohorts. The mean number of days spent in the ICU increased significantly from 1.7 ± 0.5 to 3.24 ± 2.5 days (t = -3.63; P = .001), and the overall length of stay increased from 1.7 ± 0.5 to 3.5 ± 4.1 days (t = 2.99; P = .004). The use of preoperative computed tomography (CT) increased significantly from 42.9 to 93.3% (χ2 = 13.25; P = .000). The most significant predictors of ICU admission were lower third molar involvement (P = .026), dysphagia (P = .020), and C-reactive protein (CRP) levels exceeding 150 mg/L (P = .039). CONCLUSIONS The use of the ICU in the management of odontogenic infection has increased significantly at the Royal Brisbane and Women's Hospital over 1 decade. The demographic data and clinical presentation of the patients admitted to the ICU did not change significantly. However, the length of ICU stay and the total length of stay have both increased. A significant increase in CT usage for odontogenic infections also occurred. Third molar infections, dysphagia, and elevated CRP might be relevant clinical predictors of a more complicated course of care requiring ICU admission. More judicious use of CT scanning, combined with prompt surgical consultation and intervention, might reduce the rate of ICU admissions for odontogenic infections.

Abstract
Odontogenic and oropharyngeal infections are
relatively common in the cervicofacial region. In rare
cases, odontogenic or peritonsillar abscesses may
spread through the deep fascial cervical spaces and
cause life-threatening complications. Odontogenic
infection is the most common cause of deep neck
infections and it accounts for 43% of the cases.
Early diagnosis, immediate antibiotic treatment, and
surgical drainage are the basis of therapeutic success.
Deep neck infections are potentially life threatening
complications if they are not diagnosed in time and
treated quickly. This case report presents clinical,
radiological features and treatment of the spread of
abscesses through cervical spaces of an unusual case
of deep neck infection that was caused by the secondary
infection of the root remnants after extraction.

Abstract
OBJECTIVE There are no studies comparing the accuracy of ultrasound and computed tomography in the same population of pediatric patients with lateral neck abscesses. This case series assesses the accuracy of the two imaging techniques. METHODS One hundred and forty imaging studies (ultrasound n=39 or CT n=101) that were performed from 2005 to 2011 prior to incision and drainage of a lateral neck mass at a tertiary care academic institution were retrospectively reviewed. All children 0-18 years of age with lateral neck abscesses who underwent CT or ultrasound imaging prior to drainage were included. Sensitivity, specificity, and positive and negative predictive values of ultrasound and CT were determined as compared to the gold standard, incision and drainage of the suspected abscess. RESULTS In children undergoing incision and drainage, the prevalence of an abscess was 89%. Ultrasound has a high specificity (100%) but a low sensitivity (53%). The positive predictive value (96%) is high while the negative predictive value is low (16%), assuming a positive abscess prevalence of 0.9. In contrast, CT has low specificity (18%) but slightly higher sensitivity (68%) compared to ultrasound. Similar to ultrasound, CT had low negative (6%) and high positive (88%) predictive values. CONCLUSIONS This study demonstrates that ultrasound may be an equivalently sensitive and more specific diagnostic tool when compared to CT in the work-up of lateral neck abscesses in children. It is safe and effective in diagnosis when there is an undetermined probability of an abscess.

Abstract
The advent and wide use of antibiotics have decreased the incidence of deep neck infection. When a deep neck infection does occur, however, it can be the cause of significant morbidity and death, resulting in airway obstruction, mediastinitis, pericarditis, epidural abscesses, and major vessel erosion. In our clinic, a patient with diffuse chronic osteomyelitis of mandible and fascial space abscess and necrotic fasciitis due to odontogenic infection at the time of first visit came. We successfully treated the patient by early diagnosis using contrast-enhanced CT and follow up dressing through the appropriate use of radiographic images.
