Trajectory of lumbar and sacral pedicular screws: Comparison between midline versus wiltse approach.

[Trajectory of lumbar and sacral pedicular screws: Comparison between midline versus wiltse approach]. Surg Neurol Int. 2017;8(Suppl 2):S18-S24 Authors: Gagliardi M, Guiroy A, Molina FF, Fasano F, Ciancio AM, Mezzadri JJ, Jalón P Abstract Objectives: To compare the posterolateral Wiltse approach and conventional Midline approach in short lumbosacral fusions in terms of the angle of convergence of pedicle screws. Methods: We retrospectively reviewed computed tomography (CT) images of 76 lumbar and sacral pedicular screws that had been placed using a conventional midline approach (CA) (n = 38) and a Wiltse posterolateral approach (WA) (n = 38). All patients underwent short lumbosacral fusions from L3 to S1 for degenerative spinal disease. Screws with a bone gap>4 mm in any direction, cases with previous pedicular implants, and those with coronal plane curves>20° were excluded. Results: Considering all implants, the angle of convergence was 23.3° (±15.8). The mean angulation in the WA group was 29.3° (±9.7), whereas in the CA group it was 17.2° (±0.6). This difference was statistically significant (P

We report the case of a 35-year-old woman who presented with sudden unexpected cardiac arrest and was brought to the emergency ward. Cardiopulmonary resuscitation was started by ambulance paramedic. On arrival, the patient was transferred to the catheterization laboratory due to sudden aborted cardiac death. The angiography was performed and dissection of the left main coronary artery, extended to the left anterior descending artery was detected. Pathological study confirmed ECPA. It appears that young and healthy patients with a history of intermittent vasospastic angina should be evaluated for ECPA.

ConclusionSingle isocenter technique was not feasible as the telecobalt unit did not have multileaf collimators and asymmetric jaws. With improved image based planning, a multi-isocentric technique was planned. By evaluating the dose distribution, beam modifications can be made and treatments can be given with acceptable toxicity.

ConclusionsIPAF seems to a distinct entity, with a low tendency to evolve in a definite CTD. Nevertheless, further studies are needed to better define the clinical evolution and the outcome of IPAF.

Authors: Chang MS, Chen NC, Hsu CY, Huang CW, Lee PT, Chou KJ, Fang HC, Chen CL Abstract Background: Encapsulating peritoneal sclerosis (EPS) is a serious complication of peritoneal dialysis (PD), with high morbidity and mortality that requires an early diagnosis for effective treatment. PD withdrawal and bacterial peritonitis are important triggers for the onset of EPS. However, few studies have focused on cases of PD withdrawal without a clinical diagnosis of peritonitis, cirrhosis, or carcinomatosis. We aimed to compare the clinical characteristics and computed tomography (CT) images of patients with or without ...

While excess regional adiposity can be partially inferred from clinical measurements, noninvasive imaging allows for direct quantification of specific fat depots. E...

Conclusion: FDG-PET/CT findings were shown to be more accurate for assessing MPM recurrence and more often led to therapy change than contrast-enhanced CT. PMID: 31827724 [PubMed]

In this study, we aimed to stress the importance of antrum wall thickness in CT examination. Method: The study included 111 patients between ages of 18 and 95 who had antral wall thickening in computed tomography and also had endoscopic evaluation performed in the same clinic. The patients were divided into two groups as benign and malignant according to the pathology results. The thickness of the antrum wall in computed tomography, hemoglobin and albumin levels, and age was compared among these two groups. Parameters with significant differences were further analyzed by multivariate analysis using logistic regression ...

Conclusion: A routine ophthalmic follow-up is recommended for all patients with established or suspected amyloidosis, independent of the biochemical type of the amyloid. Close collaboration between the ophthalmologist and the internist will facilitate a more precise diagnosis of ocular involvement in amyloidosis and allow the multidisciplinary management of these patients.Abbreviations: CD: corneal dystrophy; CLA: corneal lattice amyloidosis; CNS: central nervous system; CT: computed tomography; FAP: familial amyloidotic polyneuropathy; GDLCD: gelatinous drop-like corneal dystrophy; GLN: gelsolin; LCD: lattice corneal dyst...
