Abstract Background Battarrea puffball mushrooms are found extensively worldwide and contain spore-containing sacs. Inhalation of the spores of similar mushrooms, such as Lycoperdon, have been implicated in cases of lycoperdonosis—a syndrome of hypersensitivity pneumonitis. We report a case of hypersensitivity pneumonitis confirmed to be secondary to Battarrea spore exposure diagnosed by broad-range PCR. Methods A 23-year-old homeless man with a history of methamphetamine use presented to the emergency department with a 2-week history of fevers, chills, productive cough, and malaise. He reported his symptoms began soon after eating a long-stemmed mushroom he found growing next to a building. He reported inhaling particles from the mushroom when he picked it up prior to eating it. He vomited within 1 hour of ingestion, and then had a worsening progression of cough and malaise over the following 2 weeks. In the emergency department, he was noted to have leukocytosis and mild elevation of transaminases. He required supplemental oxygen due to hypoxemia. CT scan of his chest demonstrated extensive bilateral nodular pulmonary infiltrates. He was admitted and started on treatment for community-acquired pneumonia. Over the next several days, he had worsening respiratory failure, and routine work up for infectious etiologies was unrevealing. To further investigate, bronchoscopy and bronchoalveolar lavage (BAL) was performed and routine bacterial, fungal and mycobacterial cultures and cytology with Gomori Methanamine-silver and acid-fast stains were negative. BAL fluid was sent for broad range DNA testing by PCR. Antibiotic therapy was stopped, and he was started on steroids to treat presumed hypersensitivity pneumonitis. He recovered rapidly and was discharged on a course of oral corticosteroids. Results After the patient was discharged, molecular testing of BAL fluid resulted with detection of Battarrea species DNA using 28s and ITS primer sets. DNA from no other pathogens was detected. Conclusion Identified through broad range DNA PCR testing, exposure to Battarrea mushroom spores may be a previously unreported cause of hypersensitivity pneumonitis. PCR testing should be considered in the workup of hypersensitivity pneumonitis with known or suspected exposure to mushroom spores. Disclosures All authors: No reported disclosures.

A 23-year-old male presented to the emergency department with one-day history of right-sided pleuritic chest pain, haemoptysis, and fever. In the emergency department, the blood pressure was 140/60 mmHg, heart rate 89/min, body temperature 40°C, respiratory rates 20 breaths/min, and oxygen saturation 98% in room air. Physical examination revealed rales and bronchial breathing in the right infrascapular region. Laboratory analysis showed raised white blood cell counts and elevated inflammation markers. Chest X-ray showed right lower lobe consolidation. Intravenous(IV) ceftriaxone and doxycycline were started for the management of community-acquired pneumonia as per the local guideline. Later, on admission, blood culture was positive for Neisseria meningitidis (N. meningitidis). Ceftriaxone was continued for 4 days, and the patient was discharged while being on oral amoxicillin (1 gm TDS) for another 3 days. He remained well during the outpatient follow-up.

In this report, we present a complicated case of community-acquired pneumonia in a 5-year-old boy. The patient first presented to the pulmonology clinic with the diagnosis of asthma and a recent history of recurrent pneumonia. Poor compliance to two courses of outpatient oral antibiotics resulted in persistent pneumonia symptoms with unresolved radiographic findings warranting parenteral antibiotics. Despite 2 symptom-free weeks, the patient returned to the emergency department with recurrence of symptoms where imaging revealed a cavitary lesion requiring a prolonged course of parenteral antibiotics. This report further supports the detrimental impact of partially treated infections related to poor compliance to antibiotic regimens.

Obturator hernias are rare but pose a diagnostic challenge with relatively high morbidity and mortality. Our patient is an elderly, thin female with an initial evaluation concerning for gastroenteritis, and further evaluation revealed bilateral incarcerated obturator hernias, which confirmed postoperatively as well as a right femoral hernia. An 83-year-old female presented to the outpatient office initially with one-day history of diarrhea and one-week history of episodic colicky abdominal pain. She returned 4 weeks later with diarrhea resolved but worsening abdominal pain and left inner thigh pain while ambulating, without changes in appetite or nausea and vomiting. Abdominal CT scan then revealed bilateral obturator hernias. Patient then presented to the emergency department (ED) due to worsening pain, and subsequently underwent hernia repair. Intraoperatively, it was revealed that the patient had bilateral incarcerated obturator hernias and a right femoral hernia. All three hernias were repaired, and patient was discharged two days later. Patient remained well postoperatively, and 15-month CT of abdomen showed no hernia recurrence.

Abstract Background Malaria diagnosis in many malaria-endemic countries relies mainly on the use of rapid diagnostic tests (RDTs). The majority of commercial RDTs used in Africa detect the Plasmodium falciparum histidine-rich protein 2 (PfHRP2). pfhrp2/3 gene deletions can therefore lead to false-negative RDT results. This study aimed to evaluate the frequency of PCR-confirmed, false-negative P. falciparum RDT results in Monrovia, Liberia. Methods PfHRP2-based RDT (Paracheck Pf®) and microscopy results from 1038 individuals with fever or history of fever (n = 951) and pregnant women at first antenatal care (ANC) visit (n = 87) enrolled in the Saint Joseph’s Catholic Hospital (Monrovia) from March to July 2019 were used to assess the frequency of false-negative RDT results. True–false negatives were confirmed by detecting the presence of P. falciparum DNA by quantitative PCR in samples from individuals with discrepant RDT and microscopy results. Samples that were positive by 18S rRNA qPCR but negative by PfHRP2-RDT were subjected to multiplex qPCR assay for detection of pfhrp2 and pfhrp3. Results One-hundred and eighty-six (19.6%) and 200 (21.0%) of the 951 febrile participants had a P. falciparum-positive result by RDT and microscopy, respectively. Positivity rate increased with age and the reporting of joint pain, chills and shivers, vomiting and weakness, and decreased with the presence of coughs and nausea. The positivity rate at first ANC visit was 5.7% (n = 5) and 8% (n = 7) by RDT and microscopy, respectively. Out of 207 Plasmodium infections detected by microscopy, 22 (11%) were negative by RDT. qPCR confirmed absence of P. falciparum DNA in the 16 RDT-negative but microscopy-positive samples which were available for molecular testing. Among the 14 samples that were positive by qPCR but negative by RDT and microscopy, 3 only amplified pfldh, and among these 3 all were positive for pfhrp2 and pfhrp3. Conclusion There is no qPCR-confirmed evidence of false-negative RDT results due to pfhrp2/pfhrp3 deletions in this study conducted in Monrovia (Liberia). This indicates that these deletions are not expected to affect the performance of PfHRP2-based RDTs for the diagnosis of malaria in Liberia. Nevertheless, active surveillance for the emergence of PfHRP2 deletions is required.

Lymphocytic Esophagitis

Abstract Background Lymphocytic esophagitis is a new and rare clinicopathological entity. It is a histological pattern characterized by lymphocytic infiltrate without granulocytes. Its etiology and clinical significance remains unclear. The clinical manifestations are typically mild, with reflux and dysphagia the most commonly reported symptoms. Aims We describe a case report of spontaneous esophageal perforation associated with lymphocytic esophagitis. Methods Case report Results A previously well 31-year-old male presented to the emergency department with acute food impaction. His antecedent symptoms were acute chest discomfort and continuous odynophagia following his most recent meal, with persistent globus sensation. The patient had no reported history of allergies, atopy, rhinitis, or asthma. A previous history of non-progressive dysphagia was noted after resuscitation. Emergent endoscopy revealed no food bolus, but a deep 6 cm mucosal tear in the upper-mid esophagus extending 24 to 30 cm from the incisors. Chest computed tomography observed small volume pneumoperitoneum consistent with esophageal perforation. The patient’s recovery was uneventful; he was managed conservatively with broad-spectrum antibiotics, proton pump inhibitor therapy, and a soft-textured diet. Endoscopy was repeated 48 hours later and revealed considerable healing with only a residual 3-4cm linear laceration. Histology of biopsies taken from the mid and distal esophagus demonstrated marked infiltration of intraepithelial lymphocytes. There were no eosinophils or neutrophils identified, consistent with a diagnosis of lymphocytic esophagitis. Autoimmune indices including anti-nuclear antibodies and immunoglobulins were normal, ruling out a contributory autoimmune or connective tissue process. The patient was maintained on a proton pump inhibitor (pantoprazole 40 mg once daily) following discharge. Nearly six months following his presentation, the patient had a recurrence of symptoms prompting representation to the emergency department. He described acute onset chest discomfort while eating turkey. Computed tomography of the chest redemonstrated circumferential intramural gas in the distal esophagus and proximal stomach. Conclusions Esophageal perforation is a potentially life-threatening manifestation of what had been considered and described as a relatively benign condition. From isolated dysphagia to transmural perforation, this case significantly expands our current understanding of the clinical spectrum of lymphocytic esophagitis. Funding Agencies None

Background: We aimed to describe red blood cell (RBC) transfusions in the emergency department (ED) with a particular focus on the hemoglobin (Hb) level thresholds that are used in this setting. Methods: This was a cross-sectional study of 12 EDs including all adult patients that received RBC transfusion in January and February 2018. Descriptive statistics were reported. Logistic regression was performed to assess variables that were independently associated with a pre-transfusion Hb level ≥ 8 g/dL. Results: During the study period, 529 patients received RBC transfusion. The median age was 74 (59–85) years. The patients had a history of cancer or hematological disease in 185 (35.2%) cases. Acute bleeding was observed in the ED for 242 (44.7%) patients, among which 145 (59.9%) were gastrointestinal. Anemia was chronic in 191 (40.2%) cases, mostly due to vitamin or iron deficiency or to malignancy with transfusion support. Pre-transfusion Hb level was 6.9 (6.0–7.8) g/dL. The transfusion motive was not notified in the medical chart in 206 (38.9%) cases. In the multivariable logistic regression, variables that were associated with a higher pre-transfusion Hb level (≥8 g/dL) were a history of coronary artery disease (OR: 2.09; 95% CI: 1.29–3.41), the presence of acute bleeding (OR: 2.44; 95% CI: 1.53–3.94), and older age (OR: 1.02/year; 95% CI: 1.01–1.04). Conclusion: RBC transfusion in the ED was an everyday concern and involved patients with heterogeneous medical situations and severity. Pre-transfusion Hb level was rather restrictive. Almost half of transfusions were provided because of acute bleeding which was associated with a higher Hb threshold.

Abstract Introduction Acute encephalopathy, while a common presentation in the emergency department, is typically caused by a variety of metabolic, vascular, infectious, structural, or psychiatric etiologies. Among metabolic causes, hyperammonemia is relatively common and typically occurs in the setting of cirrhosis or liver dysfunction. However, noncirrhotic hyperammonemia is a rare occurrence and poses unique challenges for clinicians. Case presentation Here we report a rare case of a 50-year-old Caucasian female with history of bladder cancer status post chemotherapy, radical cystectomy, and ileocecal diversion who presented to the emergency department with severe altered mental status, combativeness, and a 3-day history of decreased urine output. Her laboratory tests were notable for hyperammonemia up to 289 μmol/L, hypokalemia, and hyperchloremic nonanion gap metabolic acidosis; her liver function tests were normal. Urine cultures were positive for Enterococcus faecium. Computed tomography imaging showed an intact ileoceal urinary diversion with chronic ileolithiasis. Upon administration of appropriate antibiotics, lactulose, and potassium citrate, she experienced rapid resolution of her encephalopathy and a significant reduction in hyperammonemia. Her hyperchloremic metabolic acidosis persisted, but her hypokalemia had resolved. Conclusion This case is an example of one of the unique consequences of urinary diversions. Urothelial tissue is typically impermeable to urinary solutes. However, when bowel segments are used, abnormal absorption of solutes occurs, including exchange of urinary chloride for serum bicarbonate, leading to a persistent hyperchloremic nonanion gap metabolic acidosis. In addition, overproduction of ammonia from urea-producing organisms can lead to abnormal absorption into the blood and subsequent oversaturation of hepatic metabolic capacity with consequent hyperammonemic encephalopathy. Although this is a rare case, prompt identification and treatment of these metabolic abnormalities is critical to prevent severe central nervous system complications such as altered mental status, coma, and even death in patients with urinary diversions.

A 79-year-old man presented to the emergency department with a 1-week history of worsening confusion, falls and hearing impairment. An initial workup for infectious, metabolic and structural causes was unrevealing. However, further history discovered that he had been ingesting one to two bottles of Pepto-Bismol (bismuth subsalicylate) daily for gastro-oesophageal reflux symptoms. On his second day of admission, the plasma salicylate concentration was 2.08 mmol/L (reference range 1.10–2.20 mmol/L), despite no sources of salicylate in hospital. He was diagnosed with chronic salicylate toxicity and Pepto-Bismol use was discontinued. The patient was treated supportively with isotonic intravenous fluids only and plasma salicylate concentration fell to less than 0.36 mmol/L. Concurrently, all his symptoms resolved. This case highlights the potential adverse effects of over-the-counter medications. The diagnosis of chronic salicylate toxicity is challenging, specifically in the elderly and in undifferentiated presentations, as it can be missed if not suspected.
