Objective: In the medical literature, thoracic disc protrusion has traditionally been considered a rare occurrence. We hypothesise that the incidence of such protrusions and their abdominal symptoms is higher than is generally believed and that their presence may account for a significant proportion of chronic non-visceral abdominal pains. Accordingly, the present study was designed to identify and quantify the symptoms experienced by patients with thoracic disc protrusion and to assess the relative risk of these symptoms being presented, compared to the general population.
Design: We conducted a cross-sectional study with a control group. The following comparison groups were analysed: case group, consisting of 100 patients diagnosed with thoracic disc protrusion in our hospital between February 2007 and October 2012, and control group consisting of 100 subjects from the general population, chosen at random. To compare the symptoms observed in each group, the following tests were applied to all study subjects: clinical examination, gastrointestinal-related quality of life (GIQLI) questionnaire and DN4 questionnaire. We also reviewed the subjects' medical records for the previous 3 years.
Results: The subjects in the case group had a significantly higher incidence of digestive-urologic symptoms, a poorer gastrointestinal quality of life and greater need of medical care than those in the control group. The differences were statistically significant for all the parameters studied. Almost all the case group subjects suffered chronic abdominal pain and/or digestive-urologic symptoms. We term this group of symptoms "chronic abdominal syndrome due to nervous compression". Nevertheless, in most cases, no neurologic aetiology was suspected, and therefore the treatment given was ineffective. In view of the results obtained, we propose a diagnostic-therapeutic algorithm for such patients.
Conclusion: Thoracic disc protrusion, as well as having a non-negligible incidence, is often associated with a digestive-urologic clinical syndrome, and this factor should be taken into account in all cases of chronic abdominal pain and other digestive-urologic symptoms when standard tests are negative, so that appropriate treatment may be given.

Acute thoracic disc herniation with severe spinal cord compression: a case report.
J Surg Case Rep
January 2025
Universidad Francisco Marroquín, 6A Calle final, Guatemala City 01010, Guatemala.
This case report highlights the rare presentation of an acute thoracic disc herniation in a 27-year-old male. Thoracic disc herniations are uncommon, accounting for less than 1% of all disc herniations, and acute presentations have scantly been recorded in literature. The patient, a mechanic, presented with a sudden onset of dorsal pain and bilateral lower limb weakness after lifting heavy equipment, leading to a sudden cease of most motor functions in the patient's lower limbs.

Background: Aneurysmal bone cysts (ABCs) are slow-growing, expansile bone tumors most often observed in the long bones and lumbar and thoracic spine. Anterior column ABCs of the spine are rare, and few cases have described their surgical management, particularly for lesions with extension into the odontoid process and the bilateral C2 pedicles. In the present case, the authors describe a two-stage strategy for resection of a symptomatic 2.

Objectives: To investigate through a meta-analysis of comparative studies the impact of donor type (brain death DBD vs circulatory death DCD) on the short- and long-term outcomes of lung transplantation(LTx).
Methods: Literature search (terms "lung transplantation" AND "donation after circulatory death") was performed up to July 2022 and studies comparing outcomes of LTx from DCD versus DBD were selected. Primary endpoints were early and long-term mortality.
Degeneration of the nucleus pulposus affects the internal volumetric strains and failure location of adjacent human metastatic vertebral bodies.

Department of Industrial Engineering, Alma Mater Studiorum - University of Bologna, Via Terracini 28, 40131 Bologna, Italy. Electronic address:
Intervertebral disc (IVD) degeneration is suspected to affect the distribution of stress and strain near the vertebral endplates and in the underlying bone. This scenario is worsened by the presence of metastatic lesions on the vertebrae (primarily thoracic vertebrae (60-80 %)) which increase the risk of fracture. As such, this study aimed to evaluate the effect of IVD degeneration on the internal volumetric strains and failure modes of human metastatic vertebral bodies.
