Objective: Primary ciliary dyskinesia (PCD) is characterized by upper and lower airway disease. Multiple studies have demonstrated the progression of pulmonary disease; however, longitudinal changes in the otologic and nasal symptoms have not been well described in patients. This study defines age-related prevalence, age of onset, and age-related trends in self-reported otologic and sinonasal comorbidities in individuals with PCD.

Article Synopsis
  • This study evaluates cardiovascular health (CVH) from early childhood to late adolescence, finding that while most children maintain high CVH during early years, there is a noticeable decline by late adolescence.
  • Using data from 1530 youths, researchers calculated CVH scores based on behaviors like diet and physical activity, revealing stability in scores until late adolescence when only 39.4% had high CVH.
  • The study highlights key sociodemographic factors associated with high CVH, such as being non-Hispanic White and having educated parents, suggesting that behavioral factors are crucial for targeted cardiovascular disease prevention efforts.

Article Synopsis
  • Prostacyclin therapy is essential for treating pulmonary arterial hypertension (PAH).
  • Inhaled prostacyclins are effective and safer than other methods since they minimize side effects throughout the body.
  • This text discusses a unique case where the use of inhaled prostacyclin led to serious complications, including bronchospasm and acute respiratory failure.

Key Clinical Message: Large uterine fibroids during pregnancy are associated with increased maternal and fetal complications. Large uterine fibroids should be kept in mind as a cause for arrest of labor and the need for cesarean delivery.

Abstract: Uterine fibroids >5 cm in diameter are more likely to grow during pregnancy and cause obstetrical complications.

Delayed Diagnosis of Ectopic Cushing Syndrome.

JCEM Case Rep

March 2024

Department of Medicine, Division of Endocrinology and Metabolism, University of North Carolina at Chapel Hill School of Medicine, Chapel Hill, NC 27599-7170, USA.

Here, we present the case of a 40-year-old man in whom the diagnosis of ectopic adrenocorticotropin (ACTH) syndrome went unrecognized despite evaluation by multiple providers until it was ultimately suspected by a nephrologist evaluating the patient for edema and weight gain. On urgent referral to endocrinology, screening for hypercortisolism was positive by both low-dose overnight dexamethasone suppression testing and 24-hour urinary free cortisol measurement. Plasma ACTH values confirmed ACTH-dependent Cushing syndrome.

Article Synopsis
  • Research shows that better rest-activity rhythms (RARs) can lower the risk of cardiovascular disease (CVD) and related health issues like hypertension and obesity.
  • Participants with more consistent and active daily patterns had significantly lower odds of prevalent CVD and obesity.
  • The study highlights the importance of stable sleep-wake routines, with earlier and restful sleep periods linked to better cardiovascular health outcomes.

Perioperative fluid administration impacts the rate of complications following surgery. VExUS grading system is a standardized point of care ultrasound (POCUS)-based, comprehensive method to assess volume status. VExUS could serve as a tool to guide fluid management, if validated perioperatively.

Rationale & Objective: Children born before 28 weeks' gestation are at increased risk of chronic kidney disease (CKD). Urine biomarkers may shed light on mechanistic pathways and improve the ability to forecast CKD. We evaluated whether urinary biomarkers in neonates of low gestational age (GA) are associated with a reduced estimated glomerular filtration rate (eGFR) over time.

Objective: Despite the increasing racial diversity of the United States, representation in academic medicine faculty does not reach concordance with the general population and worsens with higher rank. Few studies have examined this within academic Otolaryngology and surgical subspecialties. This project aims to compare rank equity in academic Otolaryngology on self-reported gender and race/ethnicity between the years 2000 and 2020.

Key Clinical Message: Amniotic band sequence (ABS) should be on the differential for newborns with limb defects. ABS is diagnosable prenatally with prenatal ultrasound; however, there are cases where the diagnosis of ABS is made only after delivery of the newborn.

Abstract: Amniotic band sequence (ABS) is an uncommon congenital disorder where strands of amniotic tissue cause entrapment of the limbs, body wall, and viscera leading to an array of congenital malformations.

Article Synopsis
  • Deprived living environments increase the risk of heart failure (HF) in non-Hispanic Black individuals, especially those in disadvantaged neighborhoods, highlighting the need for better understanding of individual risk factors.
  • The study used data from 1,448 Black individuals to examine how neighborhood disadvantage contributes to HF through accelerated biological aging and is influenced by psychosocial factors like negative affect and optimism.
  • Results showed that higher negative affect increased the risk of HF linked to neighborhood disadvantage, indicating the importance of addressing both neighborhood and individual psychosocial factors in interventions.

Article Synopsis
  • Prevention strategies for standard modifiable cardiovascular risk factors (SMuRFs) are crucial for improving outcomes in cardiovascular disease, but acute myocardial infarction (AMI) can still occur in individuals without SMuRFs.
  • A study analyzed AMI hospitalizations from 2000 to 2014 and found that 3.6% of patients had no documented SMuRFs, often receiving fewer medical treatments and procedures.
  • Patients without SMuRFs had significantly higher mortality rates within 28 days and 1 year after hospitalization for AMI compared to those with SMuRFs, highlighting the need for better early risk identification and tailored treatment strategies for this group.

While regional anaesthesia plays a pivotal role in the perioperative management of patients undergoing upper extremity surgery, its utility can be limited by the risk of hemi-diaphragmatic paresis. Furthermore, each approach to blocking the brachial plexus has associated limitations that may result in incomplete upper extremity anaesthesia. We describe the combination of three upper extremity nerve blocks to achieve surgical anaesthesia of the whole arm for a patient who had previously undergone a contralateral pneumonectomy.

Background: Endovascular management of thoracoabdominal aneurysms (TAAA) is becoming more common. Technological advances including custom devices under the Physician-Sponsored Investigational Device Exemption (PS-IDE), physician-modified endografts (PMEG), and parallel stenting techniques have expanded the extent of disease that is amenable to endovascular treatment. Patients within the PS-IDE studies are a highly selected group of patients, whereas patients treated with PMEG as captured within the Society for Vascular Surgery Vascular Quality Initiative (SVS VQI) represent a real-world experience.

Objective: The purpose of this 2-part study is to determine opioid prescribing patterns and opioid use and pain control after discharge following closed reduction of pediatric forearm fractures.

Methods: A retrospective study was conducted from December 2016 to January 2018 at a level 1 trauma center to determine opioid prescribing habits for patients 1-17 years old with forearm fractures treated with closed reduction. A prospective study was then conducted from August 2019 to October 2020 to determine pain control and opioid use after discharge.

Article Synopsis
  • Mechanical circulatory support devices like the intra-aortic balloon pump (IABP) and Impella are commonly used in patients experiencing cardiogenic shock on veno-arterial extracorporeal life support (VA-ECLS), despite a lack of extensive clinical trial data.
  • Between 2016 and 2018, the use of Impella with VA-ECLS increased from 10% to 18%, while IABP usage only saw a modest rise from 25% to 26%.
  • Despite a decrease in in-hospital mortality rates, adding IABP or Impella to VA-ECLS did not significantly change mortality or length of hospital stay, indicating the need for further research on the best practices for timing

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are conditions characterized by an immune-mediated skin reaction that results in blistering and epidermal detachment. Most cases are caused by drug hypersensitivity; however, recently there have been many publications documenting the association between coronavirus disease 2019 (COVID-19) and SJS/TEN. Our objective is to explore a case of a 4-year-old female who presented with a papular rash on her thighs that progressively worsened and spread to her face, trunk, and genital area.
