Objectives To assess the effect of thoracic paravertebral block (PVB) on pain management and preservation of pulmonary function compared with intravenous, patient-controlled analgesia (IVPCA) in patients with multiple rib fractures (MRFs). Methods Ninety patients with unilateral MRFs were included in this prospective study and randomly assigned to the TPVB or IVPCA group. The visual analogue scale (VAS) pain score, blood gas analysis, and bedside spirometry were measured and recorded at different time points after analgesia...

Burned-out tumor is a rare phenomenon in which a testicular tumor regresses in the primary lesion and progresses in a metastatic lesion. We report the case of a 30-year-old male with burned-out seminoma revealed by open biopsy of solitary 10th rib bone metastasis. He underwent inguinal orchiectomy, which revealed hyalinization, indicating a spontaneously regressed testicular tumor. Chemotherapy for seminoma was administered in three cycles of bleomycin + etoposide + cisplatin therapy. The chemotherapy was effective, and wide resection of the rib was subsequently performed...

BACKGROUND: The importance of the cervical vertebrae as part of the skull-neck system in facilitating the success and diversity of tetrapods is clear. The reconstruction of its evolution, however, is problematic because of the variation in the number of vertebrae, making it difficult to identify homologous elements. Quantification of the morphological differentiation in the neck of diverse archosaurs established homologous units of vertebrae (i.e. modules) resulting from Hox gene expression patterns within the cervical vertebral column...

BACKGROUND: Cardiac tamponade due to aortic injury after blunt trauma is a rare and potentially fatal injury. Most aortic injuries caused by blunt trauma present as aortic dissection or rupture of the aortic isthmus. Several cases of delayed aortic injury have been reported. However, all of these injuries were observed in the descending aorta because they had been caused by a posterior rib fracture. CASE PRESENTATION: We report the first case of cardiac tamponade associated with delayed ascending aortic perforation 2 weeks after blunt trauma...

Well preserved thoracic vertebrae of Neandertals are rare. However, such fossils are important as their three-dimensional (3D) spatial configuration can contribute to the understanding of the size and shape of the thoracic spine and the entire thorax. This is because the vertebral body and transverse processes provide the articulation and attachment sites for the ribs. Dorsal orientation of the transverse processes relative to the vertebral body also rotates the attached ribs in a way that could affect thorax width...

Thoracotomy results in chronic postoperative pain (CPTP) in half of the cases. Earlier findings in rat models of persistent post-surgical pain suggest that spinal pathways are critical for pain onset but not its maintenance. Descending systems from the brain stem modulate nociceptive transmission in the spinal cord and contribute to persistent pain, but their role in chronic postoperative pain has not been studied. Here, we ablated pronociceptive neurokinin-1 receptor (NK-1R)-expressing neurons in the rat rostral ventromedial medulla (RVM) to identify their role in CPTP...

Neurogenic thoracic outlet syndrome (nTOS) resulting from an isolated first rib fracture is extremely infrequent. We report a case of performance limiting nTOS in a college athlete who was initially evaluated and treated for upper extremity ligamentous injury with only transient improvement. Subsequent noninvasive studies were consistent with TOS physiology and MRA showed a large hypertrophic callus on the first rib adjacent to the brachial plexus. With continued athletic limitations and radiographic findings consistent with TOS, surgical decompression was performed resulting in resolution of symptoms...

AIM: There are few complications associated with harvesting of full thickness coastal cartilage grafts i.e., pneumothorax (0.9%), contour deformities and prolonged post-operative pain. To address these issues, authors devised special scalpel to harvest split-thickness costal cartilage grafts. MATERIALS AND METHODS: Standard inframammary incision was used for harvesting rib. Incision was made directly over the desired rib. Specially designed scalpel was used to cut through the rib cartilage to the half of the thickness...

OBJECTIVE: To optimize maximal respiratory responses with surface stimulation over abdominal and upper thorax muscles and using a 12-Channel Neuroprosthetic Platform. METHODS: Following instrumentation, six anesthetized adult canines were hyperventilated sufficiently to produce respiratory apnea. Six abdominal tests optimized electrode arrangements and stimulation parameters using bipolar sets of 4.5 cm square electrodes. Tests in the upper thorax optimized electrode locations, and forelimb moment was limited to slight-to-moderate...

Elderly populations have a higher risk of rib fractures and other associated thoracic injuries than younger adults, and the changes in body morphology that occur with age are a potential cause of this increased risk. Rib centroidal path geometry for 20 627 ribs was extracted from computed tomography (CT) scans of 1042 live adult subjects, then fitted to a six-parameter mathematical model that accurately characterizes rib size and shape, and a three-parameter model of rib orientation within the body. Multivariable regression characterized the independent effect of age, height, weight, and sex on the rib shape and orientation across the adult population, and statistically significant effects were seen from all demographic factors (P < 0...

Introduction: Deep sternal wound infections (DSWI) are a rare but devastating complication after median sternotomy. Minor perfusion in bone and soft tissue, especially after recruiting the internal mammary artery for bypass supports the development of wound infection and nonunion of the sternal bone. The aim of the study was the macroscopic and radiological presentation of the vascular system supplying the sternum, in particular the compensating blood supply routes in the event that the internal mammary artery is no longer available after use as a bypass vessel...

BACKGROUND: About 75% of patients with minor thoracic injury are discharged after an emergency department visit. However, complications such as delayed hemothorax can occur. We sought to derive and validate a clinical decision rule to predict hemothorax in patients discharged from the emergency department. METHODS: We conducted a 6-year prospective cohort study in 4 university-affiliated emergency departments. Patients aged 16 years or older presenting with a minor thoracic injury were assessed at 5 time points (initial visit and 7, 14, 30 and 90 d after the injury)...

The male imagoes, larvae, and eggs of Ameletus allengaensis sp. nov. and Ameletus sirotskii sp. nov. from the Russian Far East are described. Based on the structure of the male genitalia, the imago and larvae of A. allengaensis sp. nov. and A. sirotskii sp. nov. are similar to those of A. camtschaticus, but the discovery of these new species and separation from A. camtschaticus were confirmed by studies of the morphology of the larvae and male imago, as well as molecular analysis. Identity of various developmental stages of the new species were confirmed by analysis of the mitochondrial gene cytochrome oxidase 1 (COI) DNA barcode, which was also used to reconstruct the phylogenetic relationships within the genus Ameletus...
