BACKGROUND: Pontocerebellar hypoplasia (PCH) describes a rare, heterogeneous group of neurodegenerative disorders mainly with a prenatal onset. Patients have severe hypoplasia or atrophy of cerebellum and pons, with variable involvement of supratentorial structures, motor and cognitive impairments. Based on distinct clinical features and genetic causes, current classification comprises 11 types of PCH. MAIN TEXT: In this review we describe the clinical, neuroradiological and genetic characteristics of the different PCH subtypes, summarize the differential diagnosis and reflect on potential disease mechanisms in PCH...

INTRODUCTION: Considering the large number of fixed functional appliances, choosing the best device for your patient is not an easy task. OBJECTIVE: To describe the development of fixed functional appliances as well as our 20-year experience working with them. METHODS: Fixed functional appliances are grouped into flexible, rigid and hybrid. They are different appliances, whose action is described here. Four clinical cases will be reported with a view to illustrating the different appliances...

A search of the medical and dental records at Evidensia Lørenskog Dyreklinikk, in Lørenskog, Norway, was conducted to identify dogs that received temporary crown extensions (TCEs) to correct linguoverted mandibular canine (LMC) teeth over a 54-month investigation period (2012-2016). Criteria for inclusion into the study were the presence of complete medical and dental records, pre- and postoperative clinical photographs and intraoral radiographs of the affected canine teeth, adequate information pertaining to the procedures performed, and at least 1 follow-up >3 months after appliance removal...

OBJECTIVE: To assess the impact of two early treatment protocols for anterior dental crossbite on children's quality of life. METHODS: Thirty children, 8 to 10 years of age, with anterior dental crossbite, participated in this study. Individuals were divided into two groups: Group 1 - 15 children undergoing treatment with an upper removable appliance with digital springs; Group 2 - 15 children undergoing treatment with resin-reinforced glass ionomer cement bite pads on the lower first molars...

The aim of this study was to investigate environmental and lifestyle factors affecting exposure to PAHs in the general population in a large city of the Middle East (Tehran) by measuring urinary monohydroxy polycyclic aromatic hydrocarbons (OH-PAHs) and establishing relationships between PAHs exposure and related factors. Urine samples were collected from 222 randomly chosen subjects who were living in the urban area of Tehran, Iran. Subjects were required to complete a detailed questionnaire aimed to document their personal and sociodemographic information, activities, cooking-related appliances, smoking history/exposure, and consumed foodstuff...

REVIEW
Mona K Marei, Rania M El Backly
Dentistry is a continuously changing field that has witnessed much advancement in the past century. Prosthodontics is that branch of dentistry that deals with replacing missing teeth using either fixed or removable appliances in an attempt to simulate natural tooth function. Although such "replacement therapies" appear to be easy and economic they fall short of ever coming close to their natural counterparts. Complications that arise often lead to failures and frequent repairs of such devices which seldom allow true physiological function of dental and oral-maxillofacial tissues...

Children with an overjet of more than 6 mm are three times more likely to receive trauma to their upper incisors than children with an average overjet. This could be complicated with avulsion of permanent incisor and with space loss for the tooth. Functional appliances are usually used to treat Class II skeletal pattern and increased overjet in growing patients. The following is a case in which the Twin Block functional appliance was used, while its classic design was modified to treat a Class II skeletal problem and to open a space for a missing maxillary central incisor...

OBJECTIVE: This study was designed to assess the morphological and histological alterations of the condyle of rats undergoing forward mandibular repositioning via functional appliance. MATERIALS AND METHODS: Functional appliances were mounted onto the upper jaws of rats. Morphological analysis was conducted on micro-CT images of sacrificed animals. Histological changes in condyle were examined by immunohistochemistry using proliferating cell nuclear antigen (PCNA), matrix metalloproteases (MMPs), vascular endothelial growth factor (VEGF), tissue inhibitors of matrix metalloproteinases (TIMP-1), interleukin 1b (IL-1β), Aggrecan and Type II collagen...

This report presents a follow up of a clinical case published five years ago by the same authors. In the previous report, the authors showed a young girl treated with a myofunctional appliance due to a mandibular condylar agenesia. After a traditional graft had failed, the patient successfully responded to the functional treatment by forming a mandibular condyle. In this new report, the authors are showing how the mandibular condyle has continued developing within normal limits and, the mandibular ramus has continued positively remodeling...

Background: Lateral Cephalometric Radiographs (LCR) are a common decision-making aid in orthodontic treatment planning and are routinely used in clinical practice. The aim of this present study was to test the null hypothesis that LCR evaluation does not alter specific components of orthodontic treatment planning in Class II patients. Materials and Methods: Records of 75 patients, who had been treated at the Department of Orthodontics, Centre of Dental Medicine, University of Zurich comprised the study material...

Epidemiological studies have illustrated that PM2.5 is closely related to cardiovascular disease (CVD), but underlying toxicological mechanisms are not yet clear. The main purpose of this study is to disclose the potential biological mechanisms responsible for PM2.5-dependent adverse cardiovascular outcomes through the appliance of genome-wide transcription microarray. From results, compared with the control group, there are 97 genes significantly altered in 2.5 μg/cm2 PM2.5 treated group and 440 differentially expressed genes in 10 μg/cm2 group...

Surgery accounts for an important part of the therapeutic arsenal of colorectal cancer treatment. In digestive cancers, ostomy devices induce the loss of anal function and control. This medical appliance generates changes affecting all aspects of patients' lives. This study explores, on the one hand, the psychological impact of colostomy on colorectal cancer patients' quality of life and on the other hand, it analyzes the correlational links between body image, self-esteem and anxiety during the stoma. Thirty-five patients with colorectal cancer participated in the study, divided into 2 subgroups: 23 were carriers of a definitive stoma and the 12 others with a temporary stoma...

Background: Patients present with malocclusions in the form of bilateral open bite with functional and esthetic challenges. These are particularly so whereby these are acquired through growth anomalies that create a change in the occlusal status whereby a patient has to adapt to the challenge of the occlusal change. While surgical intervention is a considered option to correct such changes, not all patients are willing to endure the consequences of this intervention and as such this report presents a conservative minimally invasive approach...
