Furthermore, we recapitulate the major theoretical architectures in the FEP by comparing our approach with the common state-space formulations.
Heterotopic ossification (HO) may cause unintended fusion in artificial disk replacement (ADR), failing to preserve motion. The reported incidence of HO varies hugely. This study aimed to determine prevalence of HO, progression, predisposing factors to occurrence and to progression, and potential effect on clinical outcomes.
Eighty-three patients treated with ADRs for cervical radiculopathy at one or two segments were extracted from a previously published RCT. Of the 83 patients, 59 had remaining ADR (79 implants) and sufficiently high-quality X-rays at 5years of follow-up to allow analysis. HO was graded on plain films according to Mehren/Suchomel. Prevalence, progression, predisposing factors and effect on clinical outcome (Neck Disability Index-NDI) were analyzed.
At 2years, HO was seen in 46/55 ADR implants (84%), severe enough to affect mobility in 27/55 (49%). At 5years, HO was seen in 92% of 79 implants, severe in 71%. Male sex was a predisposing factor to HO. No predisposing factors to progression were identified. NDI was not affected by the severity of HO.
Almost all ADR implants in our study have HO at 5years of follow-up. Male sex is a risk factor. Severe HO did not affect clinical outcome.

To identify and critically appraise studies evaluating psychometric properties of functionally oriented diagnostic classification systems for Non-Specific Chronic Low Back Pain (NS-CLBP).
This review employed methodology consistent with PRISMA guidelines. Electronic databases and journals (PubMed, EMBASE, Cochrane, PEDro, CINAHL, Index to chiropractic literature, ProQuest, Physical Therapy, Journal of Physiotherapy, Canadian Physiotherapy and Physiotherapy Theory and Practice) were searched from inception until January 2020. Included studies evaluated the validity and reliability of NS-CLBP diagnostic classification systems in adults. Risk of bias was assessed using a Critical Appraisal Tool.
Twenty-two studies were eligible Five investigated inter-rater reliability, and 17 studies analyzed validity of O'Sullivan's classification system (OCS, n = 15), motor control impairment (MCI) test battery (n = 1), and Pain Behavior Assessment (PBA, n = 1). Evidence from multiple low risk of bias studies demonstrates that OCS has moderate to excellent inter-rater reliability (kappa > 0.4). Also, two low risk of bias studies support of OCS-MCI subcategory. Three tests within the MCI test battery show acceptable inter- and intra-rater reliability for clinical use (the "sitting knee extension," the "one leg stance," and the "pelvic tilt" tests). Evidence for the reliability and validity of the PBA is limited to one high bias risk study.
Multiple low risk of bias studies demonstrate strong inter-rater reliability for OCS classification specifically OCS-MCI subcategory. Future studies with low risk of bias are needed to evaluate reliability and validity of the MCI test battery and the PBA.

Optical coherence tomography-based criteria and classification systems were recently proposed for uniform diagnoses and treatment recommendations for patients with vitreomacular traction, epiretinal gliosis and the various forms of macular holes. learn more This article provides an overview of the different retinal imaging modalities as well as the currently recommended classification for vitreomacular traction pathologies.
Bilateral medial rectus muscle recession with or without Cüppers' posterior fixation suture and recess and resect surgery are used to correct for large angle esotropia. There are only few reports on three muscle surgery (3MS). We analyzed the results of 3MS.
Between June 2016 and May 2020, 61patients received 3MS for esotropia ≥ 27° (50PD) together with oblique muscle surgery, if needed. Angles of strabismus were measured by simultaneous prism and cover testing (SPCT) and alternating prism and cover testing (APCT) at 5 m and 0.3 m. Grading was around 0.51 mm/degree (at 5 m). Medium-term results of 57patients were available.
Medians and ranges (min-max) were age, 6years (3-56 years). Preoperative APCT, far 34° (27-45°), near 36° (27-50°). Amount of surgery, 17 mm (15-21 mm), oblique muscle recession in 21cases. The APCT after 5months (3-24 months), far 2° (-10-18), near 2° (-8-18). Success rates (absolute deviation ≤ 6° [10PD]), APCT far 68%, near 67%, SPCT far 79%, near 74%. Exotropia > 6° occurred in 4cases (7%) at far and 3(5%) at near, esotropia > 6° in 14cases (25%) at far and 16 (28%) at near.
The use of 3MS is asuitable first step procedure to correct for large angle esotropia.

Laparoscopic Heller Myotomy (LHM) with partial anterior or posterior fundoplication is the standard surgical procedure for treating achalasia patients. The results reported are mainly based on symptomatic evaluations and have less than 5years of follow-up and none more than ten.
To determine the late results of LHM, performing endoscopic, histologic, manometric, and functional studies in addition to clinical evaluations.
Eighty-nine consecutive patients were included in a prospective study from 1993 to 2008. Inclusion criteria corresponded to achalasia patients with Types I to III (radiological evaluation). Exclusion criteria included patients with grade IV, patients with previous procedures (surgical or endoscopic), or giant hiatal hernia. They were submitted to a radiological evaluation, over two endoscopic procedures with biopsy samples, manometric assessments, and 24-h pH monitoring late after surgery.
There was no operative mortality nor postoperative complications. The average hospital stay was two days.
