STUDY DESIGN: A retrospective study. OBJECTIVE: The goal of this retrospective study was to describe the uncommon presentation of neurological deficits in patients with congenital kyphosis of the upper thoracic spine (T1-T4). SUMMARY OF BACKGROUND DATA: Congenital kyphosis is an uncommon deformity but can potentially lead to spinal cord compression and paraplegia, particularly in type I (failure of formation) deformities. Few reports have described compressive myelopathy associated with congenital kyphosis of the upper thoracic spine...

STUDY DESIGN: A retrospective comparative study OBJECTIVE:: To compare 1-stage posterior corpectomy to decompression with fusion for the control of thoracic cord compression due to a metastatic tumor. SUMMARY OF BACKGROUND DATA: Thoracic cord compression by a metastatic tumor can cause back pain, paralysis, and urinary/bowel dysfunction and is generally treated by palliative decompressive surgery. However, no studies have assessed the advantages of 1-stage posterior corpectomy compared with decompression with fusion...

A bronchopleural fistula (BPF) is a communication between the pleural space and the bronchial tree. BPFs are challenging to diagnose and are associated with a high morbidity and mortality. Sequential balloon occlusion is commonly used for localization of a BPF. We describe our experience with 4 cases of successful localization of the BPF by instillation of methylene blue into the pleural space through a pigtail catheter, with simultaneous bronchoscopic visualization of dye in the tracheobronchial tree. Two patients were treated with endobronchial valves and 3 had a surgical thoracic muscle flap placed...

Regional procedures for postthoracotomy pain control have classically focused on paravertebral blocks and thoracic epidurals; however, these techniques may be challenging in an increasingly obese population and contraindicated with numerous anticoagulant and antiplatelet agents. While less studied, truncal blocks allow analgesic intervention for this growing patient cohort. This case report describes placement of a deep serratus anterior plane catheter in an intubated, morbidly obese patient with a lumbar drain who failed extubation secondary to acute postthoracotomy pain...

We report the use of continuous electrical stimulation to assist with the preoperative placement of a thoracic epidural which was used to provide postoperative analgesia in a patient undergoing excision of a large scapular sarcoma. The size of the sarcoma and the surrounding area required to maintain a sterile surgical field necessitated that the epidural catheter be inserted several vertebral interspaces caudal to the level of desired catheter tip termination. The use of electrical stimulation allowed for sequential intercostal muscle stimulation during threading, which enabled the placement of the catheter tip at the appropriate spinal level to optimize analgesia...

In previous studies, one of the systolic time intervals - preejection period (PEP) - was used as an index of sympathetic activity reflecting the cardiac contractility. However, PEP could be also influenced by several other cardiovascular variables including preload, afterload and diastolic blood pressure (DBP). The aim of this study was to assess the behavior of the PEP together with other potentially confounding cardiovascular system characteristics in healthy humans during mental and orthostatic stress (head-up tilt test - HUT)...

Hospital acquired pneumonia (HAP) and ventilatorassociated pneumonia (VAP) are common hospital-acquired infections with higher mortality, longer hospital stay and more hospitalization expenses. With the latest research results and evidence-based guideline methodology, Infectious Diseases Society of America (IDSA) and American Thoracic Society (ATS) have collaborated to create updated guidelines for the diagnosis and treatment of HAP and VAP in 2016. It is worth critically reading and thinking that most recommendations are supported by low-quality or very-low quality evidence and some strong recommendations is different from the actual clinical work in China...

PURPOSE: To determine the incidence of pseudarthrosis at the osteotomy site after three-column spinal osteotomies (3-COs) with posterior column reconstruction. METHODS: 82 consecutive adult 3-COs (66 patients) with a minimum of 2-year follow-up were retrospectively reviewed. All cases underwent posterior 3-COs with two-rod constructs. The inferior facets of the proximal level were reduced to the superior facets of the distal level. If that was not possible, a structural piece of bone graft either from the local resection or a local rib was slotted in the posterior column defect to re-establish continual structural posterior bone across the lateral margins of the resection...

Liposarcoma, one of the most common soft-tissue sarcomas, originates from primitive mesenchymal cells, and its diagnostic criteria have been well established. Myxoid liposarcoma is the second most common histological subtype, occurring more frequently during the fourth and fifth decades of life. There are only a few sporadic published cases of spinal liposarcomas, whatever primary or metastatic. We describe an unusual case of primary myxoid liposarcoma of the thoracic spine in a 79-year-old male, presented with a 2-month history of intractable dorsal pain and progressive weakness of lower limbs...

Ascending thoracic aortic aneurysm (ATAA) is a multifactorial disease with a strong inflammatory component. Surgery is often required to prevent aortic rupture and dissection. We performed gene expression analysis (Illumina HumanHT-12 version 3 Expression BeadChip) for 32 samples from ATAA (26 without/6 with dissection), and 28 left internal thoracic arteries (controls) collected in Tampere Vascular study. We compared expression profiles and conducted pathway analysis using Ingenuity Pathway Analysis (IPA) to reveal differences between ATAA and a healthy artery wall...

We assayed the toxicity of polystyrene nanoparticles (PS-NP, 52 nm) to Daphnia galeata. Survival and reproduction were significantly decreased in individuals exposed to 5 mg/L of PS-NP for 5 days, and embryos showed abnormal development, including a low hatching rate. Using fluorescence confocal microscopy, we recorded the transfer of PS-NP from the external surface of the body to the internal organs, including the thoracic appendices, ovaries, caudal appendices, and brood chamber, as well as PS-NP storage in lipid droplets...

In persons with spinal cord injury, lower thoracic low frequency spinal cord stimulation (LF-SCS, 50Hz,15mA) is a useful method to restore an effective cough. Unfortunately, the high stimulus amplitude requirements and potential activation of pain fibers significantly limits this application in persons with intact sensation. In this study, the mechanism of the expiratory muscle activation, via high frequency SCS (HF-SCS;500Hz,1mA) was evaluated in dogs. In group one, the effects of electrode placement on airway pressure generation (P) was evaluated...

Ontogenetic studies help us understand the processes of evolutionary change. Previous studies on Neandertals have focused mainly on dental development and inferred an accelerated pace of general growth. We report on a juvenile partial skeleton (El Sidrón J1) preserving cranio-dental and postcranial remains. We used dental histology to estimate the age at death to be 7.7 years. Maturation of most elements fell within the expected range of modern humans at this age. The exceptions were the atlas and mid-thoracic vertebrae, which remained at the 5- to 6-year stage of development...

Variation in the origin of the internal thoracic arteries has been previously described and reported in the literature; however, there has been no report of an anomalous termination of the right internal thoracic artery (RITA) in the pulmonary vein persisting and presenting in adult life. We report the case of a right internal thoracic artery originating from the first part of the subclavian artery but terminating in the right superior pulmonary vein that presented during the third decade of life.
