Skull base osteomyelitis is 1 of the complications of a middle ear infection seen mainly in immunocompromised individuals. A 3-phase bone scan and clinical, laboratory, and other radiological imaging are used for the diagnosis. However, in previously operated cases, bone scan findings are not reliable. We present a case of a 70-year-old man with persistent ear discharge postsurgery and with 3-phase bone scan negative for active infection. However, a subsequent 18F-FDG-labeled autologous leukocyte PET/CT study was able to diagnose the presence of active infection.

Recent evidence has demonstrated high expression of somatostatin receptors in neuroblastoma (NB) cells. Because of this, we endeavored to evaluate the diagnostic performance and clinical efficacy of 68Ga-DOTATATE PET/CT and peptide receptor radionuclide therapy (PRRT) using 177Lu-DOTATATE combined with chemotherapy in pediatric NB patients.

In total, 14 pediatric patients with histopathologically confirmed NB underwent 68Ga-DOTATATE PET/CT. Among them, the patients who were refractory or relapsed after therapy with 131I-MIBG and had intensive uptake of 68Ga-DOTATATE were referred for PRRT using 177Lu-DOTATATE. Treatment response based on follow-up imaging was classified into complete response, partial response, stable disease, and progressive disease. After each cycle of PRRT, laboratory tests were performed for evaluation of hematological, renal, and hepatic toxicities. The CTCAE (Common Terminology Criteria for Adverse Events; version 4.03) was used for grading adverse event. Curie score and Internationaging with 68Ga-DOTATATE PET/CT in such patients has a relatively high detection efficacy, demonstrating its potential use as an alternative imaging tool to conventional modalities such as 123I/131I-MIBG. However, further well-designed trials are highly warranted.
Solitary non-Hodgkin lymphoma of the trachea is extremely rare. Herein, we reported a case of solitary laryngotracheal lymphoma in a 55-year-old man. He complained of cough, tachypnea, and dyspnea. Mezigdomide 18F-FDG PET/CT showed a hypermetabolic lesion in the subglottic larynx and upper cervical trachea. The subsequent histology and immunohistochemistry of the laryngotracheal lesion tissue confirmed the diagnosis of non-Hodgkin lymphoma (mucosa-associated lymphatic tissue lymphoma).

It is largely unknown how often physicians in emergency helicopter medical services (HEMS) encounter various critical care events and if HEMS exposure is associated with particular practice patterns or outcomes.

This study aimed to describe the frequency and distribution of critical care events; to investigate whether HEMS exposure is associated with differences in practice patterns and determine if HEMS exposure factors are associated with mortality.

A retrospective registry-based study.

Physician-staffed HEMS in Finland between January 2012 and August 2019.

Ninety-four physicians who worked at least 6 months in the HEMS during the study period. Physicians with undeterminable HEMS exposure were excluded from practice pattern comparisons and mortality analysis, leaving 80 physicians.

The primary outcome measure was a physician's average annual frequencies for operational events and clinical interventions. Our secondary outcomes were the proportion of missions cancelled or denied, time onsite (OST)ated with differences in practice patterns. Rare HEMS patient contacts may be associated with increased mortality.
Prehospital exposure is distributed unevenly, and some physicians receive limited exposure to prehospital critical care. This seems to be associated with differences in practice patterns. Rare HEMS patient contacts may be associated with increased mortality.
Our objective was to investigate whether women, people 65 yrs and older, or individuals who identify with racial and/or ethnic minority groups, were underrepresented among participants in rehabilitation clinical trials.

This is a cross-sectional study of completed rehabilitation clinical trials investigating the number and percentage of women, older adults, and racial and/or ethnic minorities enrolled in rehabilitation clinical trials between January 1, 2011, and January 1, 2020. Secondary outcome measures were inclusion by diagnostic group, as well as International Classification of Functioning, Disability and Health category, and intervention by diagnostic group.

Of the 108 studies meeting inclusion criteria, a majority (69%) were based in the United States. Stroke was the most frequent diagnostic group, followed by musculoskeletal conditions. Ninety-six percent of the United States-based trials included at least one female participant in their study, but among specific diagnostic groups, this ranged clinical trials women, older individuals, and racial/ethnic minorities were generally underrepresented. In contrast, Black or African American participants were overrepresented with the exception of cardiac trials. An important finding was that many trials did not report age and/or race/ethnicity. Investigators should aim to include underrepresented populations and improve reporting.
