Pneumatosis intestinalis (PI), defined as intestinal intra- and extramural gas accumulation, is a rare radiographic finding in conditions of intestinal wall damage of varied etiology. Here, we report on a 56-year-old female with multiple myeloma who presented with undulating fever, fluctuating abdominal symptoms, and a distended abdomen 5 months after allogeneic hematopoietic stem cell transplantation (HSCT). Abdominal X-ray and CT scan documented PI with gas accumulation both in the intestinal and colonic bowel walls...

The circadian clock is rhythmically expressed in blood vessels, but the interaction between the circadian clock and disturbed blood flow remains unclear. We examined the relationships between BMAL1 and CLOCK and 2 regulators of endothelial function, AKT1 and endothelial nitric oxide synthase (eNOS), in vascular regions of altered blood flow. We found that the aortic arch from WT mice exhibited reduced sensitivity to acetylcholine (Ach)-mediated relaxation relative to the thoracic aorta. In Clock-mutant (mut) mice the aorta exhibited a reduced sensitivity to Ach...

OBJECTIVE: Increased use of robotically assisted thoracic surgery (RATS) necessitates effective credentialing guidelines to ensure safe outcomes. We provide a stepwise algorithm for granting privileges and credentials in RATS. This algorithm reflects graduated responsibility and complexity of the surgical procedures performed. Furthermore, it takes into account volume, outcomes, surgeon's competency, and appropriateness of robot usage. METHODS: We performed a literature review for available strategies to grant privileges and credentials for implementing robotic surgery...

BACKGROUND AND OBJECTIVES: Thoracic epidural analgesia can reduce postoperative pain and cardiopulmonary morbidity, but it is associated with a high rate of clinical failure. Up to 50% of clinical failure is thought to be related to technical insertion. In this study, patients undergoing thoracic surgery were randomized to one of two catheter insertion techniques: fluoroscopically guided or conventional loss of resistance with saline/air. Our primary aim was to examine whether fluoroscopic guidance could increase the incidence of correct catheter placement and improve postoperative analgesia...

Aneurysms are local dilations of an artery that predispose the vessel to sudden rupture. They are often asymptomatic and undiagnosed, resulting in a high mortality rate. The predisposition to develop thoracic aortic aneurysms is often genetically inherited and associated with syndromes affecting connective tissue homeostasis. This review discusses how elucidation of the genetic causes of syndromic forms of thoracic aortic aneurysm has helped identify pathways that contribute to disease progression, including those activated by TGF-β, angiotensin II and Notch ligands...

Companion rats are often presented to veterinarians for respiratory difficulties. Dyspnea in rats is most commonly due to infectious pneumonia, and thoracic neoplasia can go undiagnosed ante mortem due to a mistaken interpretation of pneumonia. In domestic carnivores, pulmonary nodular patterns have been shown to correlate with lung neoplastic diseases and infectious diseases. The main objective of this retrospective case series study was to determine whether certain radiographic criteria could be correlated with the presence of thoracic infectious disease and neoplastic disease in companion rats...

Wei Ding, Yinjia Ding, Hua Jiang
BACKGROUND: Although reduction mammaplasty is one of the most common procedures in plastic surgery, it is associated with some serious complications, especially in cases of severe hypertrophy or advanced ptosis, including necrosis of the nipple and areola, absence of normal sensation of the nipple-areolar complex, and loss of lactational function for future nursing. A thorough understanding of the breast anatomy is vital for successful reduction mammaplasty. This article describes the blood supply and innervation of the breasts, and introduces a modified round block technique for reduction mammaplasty based on this anatomy...

REVIEW
Hitoshi Matsuda
Hospital mortality after the replacement of chronic type B aortic dissection is around 8-10% and adverse outcomes include paraplegia and stroke. However, the level of evidence for indication of thoracic endovascular aortic repair (TEVAR) for type B chronic aortic dissection is Class IIa. Results of the INSTEAD-XL trial have verified that preemptive TEVAR for uncomplicated type B aortic dissection improves prognosis. The indication for this procedure is reportedly a maximum aortic diameter >40 mm during the acute phase and a patent primary entry site in the thoracic aorta, while the optimal timing for TEVAR would be the subacute phase, from 2 weeks to 3-6 months after onset...

BACKGROUND: Only a few studies, involving small numbers of patients, have globally assessed the curvature of the thoracic aorta but without any details concerning the location of the supra-aortic trunks. OBJECTIVES: Using CT to describe normal aortic-arch morphology and its changes with age and sex. METHODS: 344 CT scans were studied. We measured the distances from the apex to the ascending and descending aorta, the curvilinear length of the entire arch, that of the segment, including bifurcations of supra-aortic vessels, and the angle, height, and shift of the arch...

Group B streptococcus (GBS) is a commonly recognized cause of sepsis and meningitis in neonatal and young infants. Invasive GBS infection is classified into early onset GBS disease (EOD, day 0-6), late onset GBS disease (LOD, day 7-89) and ultra late onset GBS disease (ULOD, after 3 months of age). ULOD is uncommon and recurrence is especially rare. We present the first recurrent case of ULOD GBS sepsis in 3-year-old girl with a past medical history of hydrops fetalis and thoracic congenital lymphatic dysplasia...

Solitary fibrous tumors (SFTs) of the spine are exceedingly rare tumors of mesenchymal origin. Most spinal SFTs arise from the thoracic spine, followed by cervical spine, and last lumbar spine with only 6 cases reported in literature. SFTs represent a wide range of neoplasms, ranging from benign to malignant. These tumors can develop a late recurrence, even after a decade or more of initial presentation, requiring long-term follow-up. We present a case of recurrent SFT of the lumbar spine with vertebral body involvement, presenting more than a decade after initial resection...

Bullet embolism to the peripheral arterial system is a rare phenomenon which frequently results in misdiagnosis due to lack of early symptoms. Embolisms can go to either arterial or venous systems with common sites of injury including the left ventricle, pulmonary vein, thoracic and abdominal aorta and peripheral arteries. Herein we present a case of a 19 year old patient with multiple gunshot wounds to the torso with a bullet embolism to the left popliteal artery necessitating embolectomy. This subsequently led to diagnosis and repair of an abdominal aortic psuedoaneurysm not clearly evident on initial imaging...

A 63-year-old man visited the clinic with numbness in the right hand. Magnetic resonance imaging demonstrated multiple low-intensity lesions in the cervical vertebrae and sacrum, which was suspicious of cervical bone metastasis. Fluorodeoxyglucose positron emission tomography/computed tomography revealed areas of increased fluorodeoxyglucose uptake in the thoracic esophagus, sternum and sacrum. A flat, elevated esophageal cancer was identified by upper gastrointestinal endoscopy, and the macroscopic appearance indicated early-stage disease...
