Risk Factors for Mortality Among Patients With Fournier Gangrene: A Systematic Review.

Background: Fournier gangrene (FG) is a form of necrotizing fasciitis involving the perineal, peri-anal, and genital structures, and has exceptionally high mortality rates. To help in early detection of high-risk patients, we aimed to systematically review factors associated with mortality from FG. Patients and Methods: Searches were conducted in PubMed, Embase and Scopus. In our review, a minimum of five patients were required and this was to exclude studies with exceedingly small sample sizes, such as case reports and small case series, with minimal relevance in comparison to larger scale studies. Patient characteristics, causative microbes, anatomic areas of infection, presence of comorbidities, severity scores, causes of FG, and complications were extracted and compared to identify factors related to mortality. Results: A total of 57 studies were included in the review. Across 3,646 study participants, the mortality rate of FG was 20.41%. The mean age of non-survivors was 61.27 years. There were more total male deaths, however, the mortality rate was higher in females. Diabetes mellitus was the most common comorbidity in those who died, but the highest mortality rate was seen in HIV patients (54.17%). Mortality rates did not differ widely among antibiotic agents. Regarding causative organisms, fungal infections had the highest rates of mortality (68.18%) and the most common microbe leading to death was Escherichia coli. Conclusions: Female gender, comorbidities, anatomic distribution, development of sepsis, and fungal infection all increased risk for mortality. Early identification of risk factors, and provision of appropriate treatment are crucial in reducing mortality rates of high-risk patients with FG.

The use of antidepressant drugs in pregnant women with epilepsy: A study from the Australian Pregnancy Register.

OBJECTIVE: To study interactions between first-trimester exposure to antidepressant drugs (ADDs) and antiepileptic drugs (AEDs), and a history of clinical depression and/or anxiety, on pregnancy outcomes and seizure control in pregnant women with epilepsy (WWE). METHODS: We examined data from the Australian Pregnancy Register of Antiepileptic Drugs in Pregnancy, collected from 1999 to 2016. The register is an observational, prospective database, from which this study retrospectively analyzed a cohort. Among the AED-exposed outcomes, comparisons were made among 3 exposure groups: (1) pregnancy outcomes with first-trimester exposure to ADDs; (2) outcomes with mothers diagnosed with depression and/or anxiety but who were not medicated with an ADD; and (3) those with mothers who were not diagnosed with depression and/or anxiety and were not medicating with ADD. Prevalence data was analyzed using Fisher's exact test. RESULTS: A total of 2124 pregnancy outcomes were included in the analysis; 1954 outcomes were exposed to AEDs in utero, whereas 170 were unexposed. Within the group of WWE taking AEDs, there was no significant difference in the prevalence of malformations in infants who were additionally exposed to ADDs (10.2%, 95% confidence interval [CI] 3.9-16.6), compared to individuals in the non-ADD-medicated depression and/or anxiety group (7.7%, 95% CI 1.2-14.2), or those without depression or anxiety (6.9%, 95% CI 5.7-8.1; P = 0.45). The malformation rates in pregnancy outcomes unexposed to AEDs were also similar in the above groups (P = 0.27). In WWE medicated with AEDs and ADDs, the frequency of convulsive seizures (P = 0.78), or nonconvulsive seizures (P = 0.45) throughout pregnancy, did not differ across comparative groups. SIGNIFICANCE: Co-medicating with ADDs in WWE taking AEDs does not appear to confer a significant added teratogenic risk, and it does not affect seizure control.
