BackgroundPyogenic spinal infections (PSIs) are a group of uncommon but serious infectious diseases that are characterized by inflammation of the endplate-disc unit. PSIs are considered more prevalent and aggressive among patients with chronic immunocompromised states. Association between PSIs and liver disease has not been systematically analyzed. The authors performed a systematic review to study baseline characteristics, clinical presentation, and mortality of patients with PSI in the setting of chronic liver disease.ObservationsThe authors presented the case of a 72-year-old female patient with chronic liver disease who presented with severe low back pain and bilateral lower weakness. Imaging studies showed T10-11 spondylodiscitis. The patient received decompression and fusion surgery with partial neurological improvement. The authors performed a systematic literature search of spondylodiscitis and liver disease, and eight published articles met the studies inclusion and exclusion criteria. These studies featured a total of 144 patients, of whom 129 met inclusion criteria (mean age, 60.5 years, range 40 to 83 years; 62% males). Lumbar infection was the most common report (67%), with Staphylococcus aureus (48%) as the main causative microorganism. Neurological compromise was present in 69% of patients. Surgical intervention occurred in 70.5% of patients, and the average duration of antibiotic treatment was 69.4 days. Postoperative complication rate was 28.5%, with a 30- and 90-day mortality of 17.2% and 24.8%, respectively.LessonsPyogenic spondylodiscitis in patients with liver disease was associated with a high rate of neurological compromise, postoperative complications, and mortality.

BackgroundPrimary spinal infections (PSIs) are a group of uncommon but serious infectious diseases that are characterized by inflammation of the endplate-disc unit. Pediatric spinal infection is rare and challenging to diagnose due to vague presenting symptoms. Most cases are conservatively managed with surgery rarely indicated. The authors performed a systematic review to study the baseline characteristics, clinical presentation, and outcomes of pediatric patients with PSIs who underwent surgical treatment.ObservationsPSI in pediatric patients might behave differently in terms of epidemiology, clinical presentation, and outcomes when compared with nonpediatric patients. Overall, PSI ultimately managed surgically in pediatric patients is associated with a high rate of localized pain, neurological compromise, and treatment failure when compared with nonsurgically managed pediatric spinal infections.LessonsPSIs managed surgically in the pediatric population were found to be caused by Mycobacterium tuberculosis in 74.4% of cases and were associated with higher rates of localized pain, neurological compromise, and treatment failure than nonsurgically managed pediatric spinal infections. Thoracic involvement (71.8%) in the spinal infection was reported most commonly in our review. When omitting the cases involving M. tuberculosis infection, it was revealed that 50% of the pediatric cases involved infection in the cervical region, suggesting increased severity and disease course of cervical spinal infections in the pediatric population. Surgical treatment is indicated only in cases of severe neurological compromise and treatment failure.

BackgroundPrimary spinal infections (PSIs) are a group of uncommon but serious infectious diseases considered more prevalent and aggressive among patients with chronic immunocompromised states. Association of PSI and solid organ transplant has not been systematically analyzed. The authors performed a systematic review analyzing clinical presentation and mortality of patients with PSI in the setting of solid organ transplant.ObservationsPSIs in patients with immunosuppressive therapy, such as those with solid organ transplant, may behave differently in terms of epidemiology, clinical presentation, and outcomes compared with nonimmunosuppressed patients. Overall PSI in solid organ transplant patients is associated with a high rate of neurological compromise, postoperative complications, and mortality.LessonsAccurate diagnosis and appropriate treatment of PSI require a multidisciplinary effort. Localized pain is the most frequently reported symptom associated with PSI. As opposed to PSI in patients without transplant, inflammatory and infectious markers such as white blood cells and C-reactive protein are often not elevated. Furthermore, the causative microorganism profile varies significantly when compared to pyogenic spinal infection in patients without transplant. Aspergillus species was responsible for spondylodiscitis in transplant patients in more than 50% of cases, and the incidence of Aspergillus infection is projected to rise in the coming years.

Objectives/Hypothesis: To determine the effect of povidone‐iodine (PVP‐I) nasal sprays on nasopharyngeal (NP) viral load as assessed by cycle threshold (Ct) on quantitative polymerase chain reaction (qPCR) of SARS‐CoV‐2 in outpatients. Study Design: Three arm, triple blinded, randomized, placebo‐controlled clinical trial. Methods: Participants were randomized within 5 days of testing positive for COVID‐19 to receive nasal sprays containing placebo (0.9% saline), 0.5% PVP‐I, or 2.0% PVP‐I. NP swabs for qPCR analysis were taken at baseline, 1‐hour post‐PVP‐I spray (two sprays/nostril), and 3 days post‐PVP‐I spray (20 sprays/nostril). Symptom and adverse event questionnaires were completed at baseline, day 3, and day 5. University of Pennsylvania Smell Identification Tests (UPSIT) were completed at baseline and day 30. Results: Mean Ct values increased over time in all groups, indicating declining viral loads, with no statistically significant difference noted in the rate of change between placebo and PVP‐I groups. The 2.0% PVP‐I group showed statistically significant improvement in all symptom categories; however, it also reported a high rate of nasal burning. Olfaction via UPSIT showed improvement by at least one category in all groups. There were no hospitalizations or mortalities within 30 days of study enrollment. Conclusions: Saline and low concentration PVP‐I nasal sprays are well tolerated. Similar reductions in SARS‐CoV‐2 NP viral load were seen over time in all groups. All treatment groups showed improvement in olfaction over 30 days. These data suggest that dilute versions of PVP‐I nasal spray are safe for topical use in the nasal cavity, but that PVP‐I does not demonstrate virucidal activity in COVID‐19 positive outpatients.

Objective: We aimed to elucidate associations between geographic location, size, and ranking of medical schools that orthopaedic surgery residents graduate from and the residencies that they match both pre-COVID-19 and post-COVID-19 pandemic by examining the 2017 to 2022 orthopaedic surgery residency cohorts., Methods: Demographics were extracted using Doximity Residency Navigator platform, the 2021 US News and World Report, and program websites. Medical schools were classified as large if they had >613 medical students. Postgraduate year 1 (PGY-1) (2021 match) and PGY-2 (2022 match) residents were classified as the COVID-19 cohort. Location was categorized as Northeast, Midwest, South, and West. Chi-square tests, Cohen's H value, and descriptive statistics were used for analysis with statistical significance set at p <0.05., Results: Four thousand two hundred forty-three residents from 160 accredited US orthopaedic residency programs (78.4%) were included. Northeastern applicants were most likely to match in the same region (p <0.01), and southern applicants were most likely to match at their home program (p <0.001). Applicants affected by the COVID-19 pandemic did not differ from their predecessors with regards to matching to the same region (p = 0.637) or home program (p = 0.489). Applicants from public medical schools were more likely to match in the same region and at their home program (p <0.001), whereas those from private medical schools were more likely to match at top-ranked residencies (p <0.001). Students from both top 25- and top 50-ranked medical schools were more likely to match at their home program (p <0.01) and attend top 20-ranked residency programs (p <0.0001)., Conclusion: These results demonstrate significant associations between matched residencies and attended medical schools' geographic location, school type, and ranking. During the pandemic, geographic trends were overall unchanged, whereas residents from large or lower-ranked schools were more likely to match at home programs, and those from private or top-ranked schools were less likely to attend top residencies., Competing Interests: Disclosure: The Disclosure of Potential Conflicts of Interest forms are provided with the online version of the article (http://links.lww.com/JBJSOA/A584)., (Copyright © 2024 The Authors.
