We present a case of inflammatory abdominal arterial aneurysms, which demonstrates the potential usefulness of PET/CT with 18F-FDG in long-term monitoring of this disease, but also demonstrates potential pitfalls in abdominal arterial aneurysm imaging with PET/CT. Imaging may be challenged as the initial presentation prior to therapy may mimic an infected aneurysm. Follow-up images may be mistaken for vascular graft infection or persistent disease.

An 80-year-old man developed high-risk prostate cancer after 7 years of active surveillance. For staging and treatment planning, a 68Ga-PSMA PET/MRI was performed. Besides the PSMA-positive primary tumor and a solitary bone metastasis in the fifth thoracic vertebral body, an intensive intrahepatic PSMA expression (SUVmax, 16.3) was suspicious for a liver metastasis. The results of a previously performed contrast-enhanced CT, a consecutively performed contrast-enhanced ultrasound, and a follow-up...

Yolk sac tumor is a rare and highly malignant germ cell tumor. We report a case of yolk sac tumor primarily in the pancreas in a 32-year-old man. He presented with pancreatitis at presentation with significantly increased serum alpha-fetoprotein (AFP). 18F-FDG PET/CT revealed diffuse enlargement of the pancreas in the neck, body, and tail portion with homogeneously increased FDG uptake, similar to the change of pancreatitis. The lesion progressively developed to a huge pancreatic mass in the follow-up...

A 51-year-old man with 30-year neurofibromatosis and 2-month elevated prostate-specific antigen and back pain underwent a 68Ga–prostate-specific membrane antigen (PSMA) PET/CT scan for possible prostate cancer. Prostate-specific membrane antigen PET/CT imaging showed no abnormal uptake of the prostate. However, in addition to PSMA uptake in his left lung, thorax, and right ilium, which was confirmed being a lung squamous cell carcinoma by a lung biopsy, widespread uptake was also observed in his...

Neurological symptoms and gastrointestinal symptoms were rare at onset in COVID-19. Here we report a 37-year-old man with vertigo, fever, and diarrhea symptoms as the first manifestation. 18F-FDG PET/CT spotted multiple ground glass opacity (GGO) lesions in the lungs, with increased tracer uptake in both lung GGOs and the whole colon. Serial CT examinations showed the emersion and dissipation of lung GGOs. We illustrate the symptoms initiation, the laboratory test results, the imaging examination,...

It is estimated that half of the adult population older than 60 years snores. This article discusses the many aspects of snoring, including impacts on bed partners, the individual who snores, and when and how to appropriately evaluate, diagnose, and treat the perpetrator. The goal is for clinicians to expand their knowledge regarding diagnosis and treatment of the phenomenon of snoring.It is estimated that half of the adult population over the age of 60 years of age snores. This chapter discusses...

A residual bone defect at the distal aspect of the adjacent second molar may occur after total removal of the lower third molar. Lower third molar coronectomy has been proved to be a safe alternative to total removal, but the extent of bone regeneration at the adjacent tooth after coronectomy is not well reported. The aim of this prospective study was to investigate the long-term bone regeneration at the distal aspect of the adjacent second molar after lower third molar coronectomy. Preoperative...

Abstract Mutations can occur throughout the virus genome and may be beneficial, neutral or deleterious. We are interested in mutations that yield a C next to a G, producing CpG sites. CpG sites are rare in eukaryotic and viral genomes. For the eukaryotes, it is thought that CpG sites are rare because they are prone to mutation when methylated. In viruses, we know less about why CpG sites are rare. A previous study in HIV suggested that CpG-creating transition mutations are more...

Abstract Arm swing movement is coordinated with movement of the legs during walking, where the frequency of coordination depends on walking speed. At typical speeds, arm and leg movements, respectively, are frequency locked in a 1:1 ratio but at slow speeds this changes to a 2:1 ratio. It is unknown if the changes in interlimb ratio that accompany slow walking speeds alters regulation of somatosensory feedback. To probe the neural interactions between the arms and legs, somatosensory...

Abstract Because the human brain is considerably larger than those of other primates, it is not surprising that its energy requirements would far exceed that of any of the species within the order. Recently, the development of stem cell technologies and single‐cell transcriptomics provides novel ways to address the question of what specific genomic changes underlie the human brain's unique phenotype. In this review, we consider what is currently known about human brain metabolism using a variety...

Abstract Sepsis is a lethal syndrome with multiple organ failure caused by an inappropriate host response to infection. Cardiac dysfunction is one of the important complications of sepsis, termed sepsis-induced myocardial dysfunction (SIMD), which is characterized by systolic and diastolic dysfunction of both sides of the heart. Mechanisms that contribute to SIMD include an excessive inflammatory response, altered circulatory, microvascular status, nitric oxide (NO) synthesis...
