From delay to diagnosis: Chronic invasive fungal rhinosinusitis presenting with facial and orbital complications.

Key Clinical Message: Early identification and management of chronic invasive fungal rhinosinusitis (CIFRS) is key to optimizing outcomes. A missed diagnosis can result in permanent vision loss, chronic facial pain, or death. We present a case of CIFRS and literature review. Abstract: This case report presents a 56-year-old female with CIFRS involving orbital and facial complications. The patient experienced delayed diagnosis despite multiple ED visits for sinusitis with progressive facial pain and ocular deficits not alleviated with antibiotics, emphasizing the importance of early identification and maintaining high clinical suspicion for CIFRS. Prompt recognition, initiation of antifungal therapy, and aggressive surgical debridement were crucial for preventing disease progression and improving the patient's quality of life.

Management and Follow-up of Massive Fetomaternal Hemorrhage Requiring High-Dose Rh Immune Globulin: A Case Report.

OBJECTIVES: Massive fetomaternal hemorrhage (FMH) is rare and reported to be the cause in approximately 3% of all fetal deaths. Maternal management of massive FMH includes prevention of Rh(D) alloimmunization in Rh(D)-negative mothers by administration of Rh(D) immune globulin (RhIG). METHODS: We describe a case of a 30-year-old O-negative, primigravida woman who presented at 38 weeks of gestation with decreased fetal movements. She underwent an emergency cesarean section and delivered an O-positive baby girl who died shortly after birth. RESULTS: The patient's FMH screen was positive, with a Kleihauer-Betke test demonstrating 10.7% fetal blood in maternal circulation. The calculated dose of 6,300 µg RhIG was given prior to discharge over 2 days using an intravenous (IV) preparation. Antibody screening a week after discharge showed anti-D and anti-C. The anti-C was attributed to acquired passive immunity from the large dose of RhIG. Anti-C reactivity waned and was negative at 6 months, but the anti-D pattern persisted at 9 months postdelivery. Negative antibody screens were noted at 12 and 14 months. CONCLUSIONS: This case highlights the immunohematology challenges of IV RhIG as well as the success in preventing alloimmunization with IV RhIG given the patient's complete resolution of anti-C and no anti-D formation, with a subsequent healthy pregnancy.

A Description of the Imaging Innovations for Placental Assessment in Response to Environmental Pollution Study.

OBJECTIVE: The aim of Placental Assessment in Response to Environmental Pollution Study (PARENTs) was to determine whether imaging of the placenta by novel multiparametric magnetic resonance imaging (MRI) techniques in early pregnancy could help predict adverse pregnancy outcomes (APOs) due to ischemic placental disease (IPD). Additionally, we sought to determine maternal characteristics and environmental risk factors that contribute to IPD and secondary APOs. STUDY DESIGN: Potential patients in their first trimester of pregnancy, who agreed to MRI of the placenta and measures of assessment of environmental pollution, were recruited into PARENTs, a prospective population-based cohort study. Participants were seen at three study visits during pregnancy and again at their delivery from 2015 to 2019. We collected data from interviews, chart abstractions, and imaging. Maternal biospecimens (serum, plasma, and urine) at antepartum study visits and delivery specimens (placenta, cord, and maternal blood) were collected, processed, and stored. The primary outcome was a composite of IPD, which included any of the following: placental abruption, hypertensive disease of pregnancy, fetal growth restriction, or a newborn of small for gestational age. RESULTS: In this pilot cohort, of the 190 patients who completed pregnancy to viable delivery, 50 (26%) developed IPD. Among demographic characteristics, having a history of prior IPD in multiparous women was associated with the development of IPD. In the multiple novel perfusion measurements taken of the in vivo placenta using MRI, decreased high placental blood flow (mL/100 g/min) in early pregnancy (between 14 and 16 weeks) was found to be significantly associated with the later development of IPD. CONCLUSION: Successful recruitment of the PARENTs prospective cohort demonstrated the feasibility and acceptability of the use of MRI in human pregnancy to study the placenta in vivo and at the same time collect environmental exposure data. Analysis is ongoing and we hope these methods will assist researchers in the design of prospective imaging studies of pregnancy. KEY POINTS: · MRI was acceptable and feasible for the study of the human placenta in vivo.. · Functional imaging of the placenta by MRI showed a significant decrease in high placental blood flow.. · Measures of environmental exposures are further being analyzed to predict IPD..

IgM Warm Autoantibodies Causing Autoimmune Hemolytic Anemia in a Pediatric Patient.

Most often, IgM-mediated autoimmune hemolytic anemia (AIHA) presents as cold agglutinin disease in the pediatric population. The IgM warm agglutinins are rare, with few reports in the literature. This case study describes a 5 year old girl with nausea, abdominal pain and jaundice, and a hemoglobin of 5.5 g/dL who was diagnosed with a warm reactive IgM AIHA. The laboratory workup revealed a pan-reactive antibody and a direct antiglobulin test negative for IgG and C3. A thermal amplitude assay revealed reactive IgM antibodies at 37°C, 30°C, 25°C, and 4°C and an antibody titer of 1:8. An adsorption for IgM-specific autoantibodies exposed underlying anti-E and anti-Cw alloantibodies. Transfusion of phenotypically matched red blood cell units supported ongoing hemolysis. The AIHA treatment included steroids followed by rituximab with complete resolution. A literature review shows variable outcomes for warm AIHA in the pediatric population and often describes the presence of warm reactive IgM-mediated AIHA as an indicator for poor prognosis.
