An Ancient Disease Hepatosplenic Schistosomiasis.

Schistosomiasis is an ancient disease still affecting more than 200 million people worldwide; calcified Schistosome eggs were discovered in Egyptian mummies (1200-900 BC). A 25-year-old man presented to the emergency department with heartburn. He immigrated to the United States from Sub-Saharan Africa. His physical exam revealed hepatosplenomegaly, and he was eventually diagnosed with Schistosomiasis.

A Zebra Diagnosis: A Case of Spontaneous Hematomyelia Associated With COVID-19.

Spontaneous non-traumatic spinal hematomyelia, characterized by intramedullary spinal hematoma, is a rare neurological emergency. Bleeding arteriovenous malformation, coagulopathies, and neoplasms are reported causes of this rare diagnosis. The authors present a case of a previously healthy man who presented with acute paraplegia and was found to have a spontaneous hematomyelia in association with covid infection. He underwent laminectomy and hematoma evacuation but did not recover any neurological function.

Impact of Preoperative Echocardiograms on In-Hospital Outcomes of Patients Undergoing Surgical Hip Fracture Repair and Their Clinical Appropriateness.

OBJECTIVES: Preoperative transthoracic echocardiograms (TTE) before hip fracture repairs are controversial. This study aimed to quantify the frequency of ordering TTE, the appropriateness of testing based on current guidelines, and the impact of TTE on in-hospital morbidity and mortality outcomes. METHODS: This retrospective chart review of adult patients admitted with hip fracture compared the length of stay (LOS), time to surgery, in-hospital mortality, and postoperative complications between TTE and non-TTE groups. TTE patients were risk stratified using the Revised Cardiac Risk Index (RCRI) to compare TTE indication according to current guidelines. RESULTS: Of the 490 patients included in this study, 15% received preoperative TTE. The median LOS of the TTE and non-TTE groups was 7.0 and 5.0 d, respectively, whereas the median time to surgery was 34 and 14 h, respectively. The odds of in-hospital mortality remained significantly higher in the TTE group after adjusting for RCRI but not when adjusted for the Charlson Comorbidity Index. Significantly more patients in the TTE groups had postoperative heart failure and up triage in the intensive care unit. Furthermore, 48% of patients with an RCRI score of 0 received preoperative TTE, with cardiac history as the most typical indication. TTE changed perioperative management in 9% of patients. CONCLUSIONS: Patients subjected to TTE before hip fracture surgery had a longer LOS and time to surgery, with higher mortality and intensive care unit up triage rates. TTE evaluations were typically conducted for inappropriate indications, which rarely made meaningful changes to patient management.

False Elevation of Troponin in a Case of Multiple Myeloma.

Falsely elevated troponin has been reported in the literature. The authors present a case of a 51-year-old man who was admitted with nausea, vomiting, and chest discomfort. He was found to have elevated troponin with no electrocardiographic changes. He has normal coronaries on angiogram and normal echocardiogram. A diagnostic time-out and second look at the laboratory values captured abnormalities that triggered a workup that ruled in a multiple myeloma diagnosis. We suspected falsely elevated troponin levels secondary to macrotroponin, a complex of elevated immunoglobulin levels and troponin, which has been rarely reported to cause elevated troponin levels in patients with multiple myeloma.

It Is Not a Boerhaave! A Case of Spontaneous Pneumothorax.

Spontaneous pneumothorax is a pneumothorax that is not caused by trauma or an apparent precipitating factor. This report presents a case of a 91-year-old man with no history of lung disease who developed pneumothorax after two days of persistent nausea and vomiting. He was misdiagnosed as a case of Boerhaave's syndrome. A chest computed tomography with iohexol oral contrast showed no evidence of esophageal rupture, and an upper endoscopy revealed a small gastric ulcer and no gastric outlet obstruction. The patient was managed conservatively; his spontaneous pneumothorax, nausea, and vomiting resolved.

Diagnostic Overshadowing and Pain Insensitivity in a Schizophrenic Patient With Perforated Duodenal Ulcer.

Some patients with schizophrenia and psychotic illnesses have reduced pain perception, and others have decreased pain expression. The diagnosis of the acute abdomen can be delayed, and its outcomes can be worse in psychiatric patients than in non-psychiatric patients. We present a case of perforated peptic ulcer (PPU) in a schizophrenic woman and discuss how the phenomenon of pain insensitivity and diagnostic overshadowing-a process in which a person with mental illness receives inadequate treatment due to a misattribution of physical symptoms to their mental illness-nearly contributed to a missed diagnosis.

A Dangerous and Unrecognized Interaction of Apixaban.

Direct oral anticoagulants (DOACs) drug-to-drug interactions are underrecognized by clinicians. Apixaban has cytochrome 450 (CYP) mediated metabolism (primarily by CYP3A4). Strong inducers and inhibitors of this enzyme may cause variations in the blood level of apixaban. This report presents a patient who received a femoral artery stent and developed a large retroperitoneal hemorrhage after she was prescribed apixaban in addition to her antiretroviral therapy (AVT) regimen that included cobicistat, a strong CYP3A4 inhibitor. The patient was managed conservatively, and a repeat computed tomography scan in a subsequent admission revealed near resolution of the hematoma. The treating physicians realized that apixaban should not be prescribed with a potent CYP3A4 inhibitor like cobicistat and discontinued it.

Discrepancy between emergency department admission diagnosis and hospital discharge diagnosis and its impact on length of stay, up-triage to the intensive care unit, and mortality.

OBJECTIVES: Published discrepancy rates between emergency department (ED) and hospital discharge (HD) diagnoses vary widely (from 6.5 to 75.6%). The goal of this study was to determine the extent of diagnostic discrepancy and its impact on length of hospital stay (LOS), up-triage to the intensive care unit (ICU) and in-hospital mortality. METHODS: A retrospective chart review of adult patients admitted from the ED to a hospitalist service at a tertiary hospital was performed. The ED and HD diagnoses were compared and classified as concordant, discordant, or symptom diagnoses according to predefined criteria. Logistic regression analysis was conducted to examine the associations of diagnostic discordance with in-hospital mortality and up-triage to the ICU. A linear regression model was used for the length of stay. RESULTS: Of the 636 patients whose records were reviewed, 418 (217 [51.9%] women, with a mean age of 64.1 years) were included. Overall, 318 patients (76%) had concordant diagnoses, while 91 (21.77%) had discordant diagnoses. Only 9 patients (2.15%) had symptom diagnoses. A discordant diagnosis was associated with increased mortality (OR: 3.64; 95% CI: 1.026-12.91; p=0.045) and up-triage to the ICU (OR: 5.51; 95% CI: 2.43-12.5; p<0.001). The median LOS was significantly greater for patients with discordant diagnoses (7 days) than for those with concordant diagnoses (4.7 days) (p=0.004). Symptom diagnosis did not affect the mortality or ICU up-triage. CONCLUSIONS: One in five hospitalized patients had discordant HD and admission diagnoses. This diagnostic discrepancy was associated with significant impacts on patient morbidity and mortality.

A Double Whammy: A Case Report and Review of the Literature on Pneumococcal Coinfection in COVID-19 Patients.

Bacterial coinfections which are infections present early in the course of coronavirus disease 2019 (COVID-19) infections before hospitalizations during the 2020 pandemic are rare. A 66-year-old male presented to the ED with a two-week history of subjective fever, dyspnea, and productive cough. He was diagnosed with coinfection of severe COVID-19 pneumonia and pneumococcal infection. He recovered from both infections and was discharged home. This report presents the features of this case and reviews the literature of similar cases of coinfection of COVID-19 pneumonia and pneumococcal infection.

Unexpected Diagnosis.

A 74-year-old man presented to the ER with an eight-month history of shortness of breath, cough, anorexia, and weight loss. He had emigrated from sub-Saharan African to the USA, where he was diagnosed and treated for coronary artery disease, heart failure, and stroke; was hospitalized several times; and underwent hernia surgery. Despite the complex care that he received in the USA for many years, the diagnosis of AIDS was continually missed for years, and the patient was eventually diagnosed at the age of 74.

Pyroglutamic Acidemia: An Underrecognized and Underdiagnosed Cause of High Anion Gap Metabolic Acidosis - A Case Report and Review of Literature.

Pyroglutamic acidemia (oxoprolinemia) is an underrecognized cause of high anion gap acidosis resulting from derangement in the gamma-glutamyl cycle. Pyroglutamic acidemia is most commonly diagnosed in the pediatric population in patients with inherited autosomal recessive enzyme deficiencies. However, acquired pyroglutamic acidemia can present in the adult population. Patients often present with confusion, nausea, and vomiting as well as an elevated anion gap metabolic acidosis. This article describes a case of acquired pyroglutamic acidemia and emphasizes the need to consider this entity.

Prevalence and Predictors of Pulmonary Embolism in Hospitalized Patients with Syncope.

OBJECTIVES: Approximately one in six patients hospitalized with syncope have pulmonary embolism (PE), according to the PE in Syncope Italian Trial study. Subsequent studies using administrative data have reported a PE prevalence of <3%. The aim of the study was to determine the prevalence and predictors of PE in hospitalized patients with syncope. METHODS: We retrospectively reviewed the records of patients who were hospitalized in the MedStar Washington Hospital Center between May 1, 2015 and June 30, 2017 with deep venous thrombosis, PE, and syncope. Only patients who presented to the emergency department with syncope were included in the final analysis. PE was diagnosed by either positive computed tomographic angiography or a high-probability ventilation-perfusion scan. Univariate and multivariate logistic regressions were used to assess the associations between clinical variables and the diagnosis of PE in patients with syncope. RESULTS: Of the 408 patients hospitalized with syncope (mean age, 67.5 years; 51% men [N = 208]), 25 (6%) had a diagnosis of PE. Elevated troponin levels (odds ratio 6.6, 95% confidence interval 1.9-22.9) and a dilated right ventricle on echocardiogram (odds ratio 6.9, 95% confidence interval 2.0-23.6) were independently associated with the diagnosis of PE. Age, active cancer, and history of deep venous thrombosis were not associated with the diagnosis of PE. CONCLUSIONS: The prevalence of PE in this study is approximately one-third of the reported prevalence in the PE in Syncope Italian Trial study and almost three times the value reported in administrative data-based studies. PE should be suspected in patients with syncope and elevated troponin levels or a dilated right ventricle on echocardiogram.

Expanding the differential: toluene-induced toxicity.

A 31-year-old woman presented to the hospital with generalised weakness and lower back and abdominal pain. The only significant finding on physical examination was the weakness of the legs. Laboratory analysis in the emergency department revealed that she was hypokalaemic with metabolic acidosis. She was treated with oral and intravenous potassium, which resolved her weakness. During the search for an explanation for her renal tubular acidosis, she said she was exposed to paint exposure while working on a friend's house. She was discharged on correction of her hypokalaemia, and a subsequent test revealed elevated blood toluene level.
