Inclusive education policies stimulate children with special educational needs, including autism, to attend regular education. We aimed to explore change over time in school placement and transitions of autistic children since the introduction of an inclusive education policy in the Netherlands (2014) and to examine the role of individual child characteristics. This study used longitudinal data from 2013 to 2021 on autistic children (N = 1463, aged 5-16 years).

To create and validate size guides for fitting Denovo plain molar bands and bands with tubes to 3M ESPE stainless steel crowned primary molars. Two size guides were created for fitting these bands to corresponding crown sizes, with an additional pre-existing guide available for comparison. Eight volunteer dentists chose their best-fit band sizes for stainless steel crowned typodont teeth, with each seeing a subset of clinical conditions as determined by a randomized factorial experiment.

The purpose of this study was to evaluate whether preoperative radiographic measurements could predict the final steel crown selection size for restoration of primary molars. A retrospective chart review of children two to 10 years old receiving oral rehabbilitation between July 2019 and May 2020 was completed. Bitewing radiographs were used to obtain two linear radiographic measurements (coronal and cervical) using DEXIS™ Imaging Software (KaVo Dental).

Stainless steel crown (SSC) placement is a common pediatric restorative treatment, generally completed with minimal complications. Discussed in this case series are two patients who presented to the emergency department (ED) with moderate oral bleeding persisting more than 12 hours after oral rehabilitation under general anesthesia. Bleeding incidence after pediatric oral rehabilitation has been found to range from 20% to 40%, with most being considered mild and significantly associated with extractions.

Despite the extensive literature regarding peripheral nerve stretch injuries, there are few studies that compare the nerve histology with the mechanical properties in humans. There is clinical evidence suggesting that the peroneal nerve is at greater risk for injury compared to the tibial nerve following total hip arthroplasty and hip trauma. We examined the two nerves from fresh human cadavers with or without controlled stretch.

Background: Successful surgical treatment of late-presenting infantile tibia vara (ITV) patient requires the correction of oblique deformities. The purpose of this study was to report on a new comprehensive approach to correct and prevent recurrence of these deformities with a single procedure.

Methods: Medical records of 23 consecutive children (7 to 18 y) with advanced ITV (29 knees) were retrospectively reviewed after a mean of 7.

Background: Amyotrophic lateral sclerosis (ALS) is poorly understood with no effective therapeutics. One long entertained observation is that ALS may be precipitated focally by nerve injury. Many patients with ALS are athletes or veterans, and some have suffered nerve injuries at the site where ALS first presents.

Background: Reinfected total knee arthroplasty can be managed with a second two-stage exchange or a knee arthrodesis procedure.

Methods: Twenty-three patients with knee arthrodesis after failed exchange arthroplasty for infection were reviewed. Patients were managed with a staged protocol of implant extraction, débridement, and implantation of an antibiotic spacer, with subsequent arthrodesis.

The purpose of this study was to quantify the changes in transfusion rates, both allogeneic blood transfusion (ALBT) and autogenic blood transfusion (ATBT) on a national scale, and determine patient factors associated with transfusions. The National Hospital Discharge Survey was evaluated between 2001 and 2010 for primary total hip arthroplasty (THA) patients and categorized on the basis of transfusion necessity, type, and comorbidity burden. A logistic regression comparison of ALBT, ATBT, and nontransfused patients was performed with respect to patient demographics and in-hospital complications.

Purpose: With the increasing number of primary total hip arthroplasties (THA) being performed, the frequency of revision surgery is also expected to increase. We analysed the immediate in-hospital complications and epidemiologic data of 3,469 revision and 18,186 primary THA cases.

Methods: The National Hospital Discharge Survey (NHDS) was evaluated between 2001 and 2010 for patients who underwent revision and primary THA.

The wish to prevent or improve scars, whether they are of surgical or traumatic origin, has led to the development of scar creams and gels that are said to influence the aesthetic appearance of a scar. In this article the literature on results of the topical application of various scar creams and gels is reviewed. It is concluded that no single modality has been proven to manage hypertrophic scarring except maybe silicone and BAPN.
