Prevalence of lumbar high-intensity zone: assessment using a screening tool independent of spinal symptoms.
Prevalence of lumbar high-intensity zone: assessment using a screening tool independent of spinal symptoms. Acta Orthop Belg. 2019 Mar;85(1):47-53 Authors: Campos M, Vial R, Castro J, Urrutia J Abstract High-intensity zone is an area of high-intensity signal within the posterior annulus fibrosus observed in magnetic resonance imaging; initially described in painful discs, recent studies have described similar prevalence in symptomatic and asymptomatic subjects. Since its' prevalence in the general population has not been established, we used a screening tool independent of spinal symptoms to determine high-intensity zone prevalence. We studied 217 patients evaluated with abdominal-pelvic magnetic resonance imaging; we looked for high-intensity zone, disc degeneration, spondylolysis, spondylolisthesis, Modic changes and scoliosis. We determined if these variables, age and sex affected the presence of high-intensity zone; through a logistic regression analysis we evaluated their independent effect. Patients' mean age was 56.3±17.4 years; 66.8% were females. Prevalence of high-intensity zone (11.06%) was larger in males (18.06%) than females (7.59%), p = 0.02. Patients with and without high-intensity zone did not differ in age or presence of scoliosis. High-intensity zone was more frequent in degenerated discs, but not in levels with spondylolisis, spondylolisthesis or Modic changes. Male sex (OR = 2.3, 1.04-5.38) and disc degeneration (OR = 6.76, 1.7...
Atypical chest pain is of diverse origin. Typically, we initially consider cardiac etiology. When pain appears non-cardiac, there is a tendency to underestimate the illness, especially if the patient has neuropsychiatric illness. Our resident with dementia and anxiety disorder had chest pain; the diagnosis was unexpected.
Chronic pain is common among older adults, as is the use of medications to treat these symptoms. Aging physiology, in combination with a higher likelihood of medication use and declining renal function, makes older adults more susceptible to adverse drug effects. As such, monitoring for side effects and changes in renal function is important to avoid drug toxicity, especially during acute illness when medication errors and acute changes in renal function are more likely to occur among older adults.
Many patients are discharged to post-acute care facilities (PACFs) following surgery. These patients have either had major surgery and require close monitoring and intensive rehabilitation, or have significant medical co-morbidities. Currently they are transported, sometimes at considerable cost, to the surgeon ’s office for post-surgery visits (PSVs). These trips can be painful and uncomfortable. A staff member from the PACF may need to accompany the patient. During PSVs surgeons observe the patient's incision(s), and assess potential complications following surgery, pain, and functional recovery.
Chronic pain is among the most common reasons for seeking medical attention. In the United States, 1 in 5 adults had chronic pain in 2016 and it is estimated to cost over $500 billion annually in direct medical costs and disability. It is a prevalent problem among residents in the nursing home. Non-pharmacologic therapies are the most preferred treatment for chronic pain as pharmacological therapies, such as opioids, have proven to be less effective and associated with numerous side effects among older adults.
CONCLUSIONS.: Our results confirm orbitofrontal structural deficits in BPD, while providing a framework and preliminary findings on identifying structural correlates of symptom dimensions in BPD, especially with dorsolateral and orbitofrontal cortices. PMID: 32093800 [PubMed - in process]
CONCLUSIONS.: Despite sharing a lower IQ and a higher prevalence of psychiatric disorders, brain abnormalities in BDo appear less pronounced (but are not absent) than in SZo. Lower ICV in SZo implies that familial risk for schizophrenia has a stronger association with stunted early brain development than familial risk for bipolar disorder.

Authors: Watanabe H, Bagarinao E, Yokoi T, Yamaguchi H, Ishigaki S, Mausuda M, Katsuno M, Sobue G Abstract Misfolded and aggregated tau and amyloid β (Aβ) proteins are the pathological hallmarks of Alzheimer's disease (AD). These aberrant proteins lose their physiological roles, acquire neurotoxicity, and propagate across neural systems. Despite the growing understanding of the molecular pathophysiology, the relationship among molecular alterations, pathological changes, and dementia onset and progression remain to be elucidated. Connectivity is an exclusive characteristic of the brain, and the integrity ...
Background: Back pain in adolescents is very common and often seen in the office for evaluation of potential spinal pathology. Pediatric back pain has often thought to be from serious identifiable causes such as spondylolysis, spondylolisthesis, tumor, or infection. A follow-up analysis of adolescents initially presenting with back pain to their eventual subsequent diagnosis within 1 year has not been reported on a large scale with a national sample. Methods: A national insurance database (PearlDiver Patient Records Database) was queried for ICD-9 codes to identify patients aged 10 to 19 years with back pain from 2007 to ...
