Severe odontogenic infection in pregnancy: a timely reminder

Severe Deep Fascial Spaces Infections with Pregnancy: A Retrospective Study

Background: Odontogenic infections are common and self-limiting in most cases, but, they can lead to severe consequences and considerable morbidity and can even be fetal in spite of modern medical therapy. Patients and Methods: Retrospective study included data of pregnant patients with deep fascial space infections, done in Oral & Maxillofacial Surgery Department, Faculty of Dentistry. Alexandria University, and Oral & Maxillofacial Surgery Department, King Fahd Specialist Hospital, Burayda, Qassim, Saudi Arabia, from June2017 to Dec2022. Data were analyzed to study incidence, etiology, pattern, treatment modalities, outcomes, complications, and effects on pregnancy. Results: Thirty-eight pregnant patients, with a mean age of 30.8 ± 6.21 years, were included. The mean age of pregnancy was 24.5 ± 4.3 weeks. Diabetes mellitus was identified in seven cases (18.42%) and combined with hypertension in one case (2.63%) and with valvular heart disease in another one. The commonest affected single space was the submandibular space that occurred in six cases (15.8%). Canine space was the second single commonly involved one which occurred in five patients (13.2%). Complications occurred in 11 patients. Unesthetic scar occurred in three patients (7.9%). Trismus was observed in two patients (5.3%). Recurrent abscess was found in one case. Complications affecting the developing fetus and considered the most serious occurred in four patients: two cases of preterm labor and two cases of abortion. Conclusion: These infections may lead to serious outcomes and may have irreversible effects on the pregnancy and the developing fetus. Urgent intervention with multidisciplinary team to provide adequate care.

Predictive Value of Inflammatory Cytokines in Early Pregnancy for Liver Dysfunction in Pregnant Women with Hepatitis B

The purpose of this study is to explore the predictive value of cytokine levels in the first trimester of pregnancy on abnormal liver function of pregnant women with hepatitis B in the third trimester of pregnancy. A total of 111 pregnant women with HBV infection at 12 weeks gestation participated in the study. The levels of IL-6, IL-8, TNF-α in peripheral blood of the patients and liver function indexes were detected. Subsequently, the pregnant women were followed up, and the liver function was detected at 36 weeks of gestation. According to liver function indexes, patients were divided into normal liver function group and abnormal liver function group to determine the correlation between cytokines in early pregnancy and abnormal liver function in late pregnancy. Kaplan-Meier survival curve and multivariate Cox analysis were used to evaluate the predictive value of cytokines for liver dysfunction. At 12 weeks of gestation, cytokine levels in the normal liver function group were significantly lower than that in the abnormal liver function group. Kaplan-Meier survival analysis showed that the increased IL-6 level was associated with abnormal liver function in late pregnancy. Multivariate Cox regression analysis revealed that IL-6 level was an independent predictor of abnormal liver function in patients with normal liver function in the late pregnancy. The high expression level of cytokine IL-6 at 12 weeks of pregnancy has noteworthy predictive significance for the abnormal liver function of hepatitis B pregnant women in third trimester of pregnancy.

Evolution of the treatment of severe odontogenic infections over 50 years: A comprehensive review

Objectives

Severe odontogenic infections remain a challenge for maxillofacial surgeons. The aim of this work is to review the literature to provide an update of knowledge on the topic.

Methods

A comprehensive review of articles in PubMed, Web of Science and Africa Journals Online was performed through searching for "severe odontogenic infections." No language restrictions were applied. Only articles pertaining to treatment options were retrieved. Articles from the past 50 years were included.

Results

A total of 84 articles from 39 countries worldwide were included. Severe odontogenic infections are not unique to low- and middle-income countries but also pose challenges in developed countries. Surgical management and antibiotic therapy for this type of infection is discussed. Some immunocompromised patients have high risks of complications and mortality rates. A world map of publications on the topic is provided.

Conclusions

Several important aspects of managing severe odontogenic infections are discussed. Predictors of severity in addition to recommended antibiotic choice have been debated. Diabetes mellitus is a poor predictor of the prognosis of odontogenic infections.

Severe Odontogenic Infections during Pregnancy and Related Adverse Outcomes. Case Report and Systematic Literature Review

Odontogenic infections have the potential to develop into deep-space infections and may cause severe diseases with possible life-threatening complications. Dental infections during pregnancy require special attention in terms of possible complications and treatments due to the potential to affect the lives of two individuals. A case of a 36-year-old pregnant patient with a submandibular abscess caused by an odontogenic infection is reported, followed by a comprehensive systematic review of the literature in order to retrieve information regarding severe odontogenic infections and adverse pregnancy outcomes. The review was conducted according to the PRISMA guidelines using PubMed, Scopus, and Google Scholar databases. A total of 69 cases were included in the qualitative analysis. The mean age was 27.72 years. Patients were managed with surgery in combination with antibiotics. Nine infectious-related cesarean sections were detected, and preterm birth was associated in 3 cases, low birth weight in 2 cases, death of the fetus in 9 cases (13%), and maternal death in 4 cases (5.8%). The possible compromise of oral health during pregnancy is well known; however, severe odontogenic infections are rarely considered in the literature, and they may be associated with severe and life-threatening complications for both mother and the fetus.

Odontogenic cervico-facial cellulitis during pregnancy: about 3 cases

Pregnancy is considered as a risk factor for development, severity, and complications of odontogenic infections. Without adequate treatment, the infection can spread and threaten both the mother's and the foetus lives. We aim to analyze the predisposing factors, diagnostic and therapeutic aspects of cervico-facial cellulitis during pregnancy, through a descriptive retrospective study conducted at oral and maxillofacial surgery department of Mohamed VI university hospital center at Marrakesh, between June 2017 and June 2019. A total of three patients; all patients were at their last trimester were recruited. Every patient was immediately given intravenous antibiotics, drainage was carried out under local anesthesia, and the causing tooth was removed. During hospitalization, one patient was referred to the gynaecology department for preterm labor, while the remaining two patients were discharged after the pus drainage has stopped. The possible compromise of oral health during pregnancy is well known, however severe odontogenic infections are rarely considered in the literature. It is essential to aggressively treat the gravid patient to minimize the risk of infection spreading to the facial spaces. Moreover, poor oral health in pregnancy has been implicated in adverse birth outcomes, specifically prematurity. We recommend upgrading communication between obstetrician and dentists so that regular routine dental visits are planned for pregnant patients during early stages of pregnancy in order to identify and manage the problem as early as possible.

Detection of opioids in umbilical cord lysates: an antibody-based rapid screening approach

In pregnancy, opioids may be used medically and also misused. We hypothesized that the umbilical cord (UC) could be a good screening tool for determining opioid exposure and improving medical care. One hundred and one UC, each with 50 associated ICD9/ICD10 codes were used. Using predictive pharmacokinetic analysis we determined that opioids could be detected since last ingestion prior to birth. The UC were lysed and screened using ELISA detecting multiple opioids and their metabolites. Statistical comparisons to obstetric and neonatal outcomes were performed. Although the commercial ELISA was less sensitive in UC than blood or urine, there was perfect method selectivity as compared to a subset of cords designated positive or negative by clinical diagnostics, so our results are accurate and reliable. Absolute quantitation was not possible because the antibody cross reacts with multiple compounds, but 'low' or 'high' levels of exposure were assigned. Prevalence of opioids was 11%, which reduced to 7% when cesarean-section births were eliminated. For non-cesarean-section infants adjusted for preterm birth, advanced maternal age and smoking (independent risk factors), opioids were significantly associated with intra-uterine growth restriction (p = 0.017) and admission to neonatal intensive care (p = 0.002). UC can be collected noninvasively and rapidly providing a reliable tools for semi-quantitative opioid screening using ELISA. Moreover, as UC are usually discarded collection presents few technical or safety concerns for staff or patients. Further development of this methodology may provide a rapid, noninvasive clinical screening tool to identify NAS and/or opioid use in late pregnancy.
