 = 0.005, odds ratio  - 4.48) (95% CI  - 8.29,  - 1.47).The surgical duration was less in the nailing group but was not significant.

Considering lesser time for union, early weight bearing, lower chances of infection and lesser surgical duration, nailing seems to be more promising for extra articular proximal tibia fractures.Further research is required on this topic to provide a definitive evidence.

They are well-established and frequently encountered in the field of orthopedics. Stress fractures occur in the bone because of low-bone strength and high chronic mechanical stress placed on the bone. Stress riser fractures are also stress fractures that occur because of the presence of cortical defects (holes), changes in stiffness, sharp corners, and cracks (fracture lines). Periprosthetic or peri-implant fractures are good examples of stress riser fractures that occur in regions where stress forces are higher than those in the surrounding material. Most stress riser fractures are related to technical errors (iatrogenic causes) and are difficult to manage. It is possible and more effective to prevent the creation of stress riser fractures through better surgical techniques. The proper terminology for stress fractures, stress riser fractures, periprosthetic fractures, peri-implant fractures, interprosthetic fractures, and interimplant fractures is discussed. This review of the current state of knowledge, diagnosis, treatment, and prevention of stress riser fractures is based on clinical evidence and recent literature.Remodeling follows inflammatory and reparative phases of bone healing and is very pronounced in children. Unlike adults, in growing children, remodeling can restore the alignment of initially malunited fractures to a certain extent, making anatomic reduction less essential. Remodeling is not universal and ubiquitous. Animal experiments and clinical studies have proven that in a malunited fracture, the angulation corrects maximally by physeal realignment (75%) and partly by appositional remodeling of the diaphysis also known as the cortical drift (25%). Remodeling potential reduces with the increasing age of the child; lower extremities have higher remodeling potential compared to the upper extremity. Remodeling is most pronounced at the growing end of the bone and in the axis of the adjacent joint motion. Correction of a very small amount of rotational malalignment is possible, but it is clinically not relevant. Overgrowth of the bone after a fracture occurs due to hyperaemia of fracture healing. Overgrowth is the most common after paediatric femur fractures, though it is reported after fractures of the tibia and humerus as well. The orthopaedic surgeon treating children's fractures should be familiar with regional variations of remodeling and limits of acceptance of angulation in different regions. Acceptability criteria for different bones are though well defined, but serve best as guidelines only. For the final decision-making patient's functional capacity, parents' willingness to wait until the completion of the remodeling process, and the experience of treating doctor should be considered concurrently. In case of the slightest doubt, a more aggressive approach should be taken to achieve a satisfactory result.TRASH lesions are a group of special injuries around the elbow resulting from high energy trauma that are routinely missed at initial presentation because of seemingly normal X-rays. These are a group of osteochondral injuries having a high propensity for surgical intervention and usually have poor outcomes if not treated adequately. Prompt diagnosis warrants a high index of suspicion even when a radiograph appears to be normal with a disproportionately swollen elbow in a child. TRASH lesions include radial head osteochondral fractures, medial condylar fractures in unossified elbow, transphyseal separations of the distal humerus, monteggia lesions, entrapped incarcerated medial epicondylar fractures, capitellar shear fractures, lateral condylar fractures extending to the cartilage. This article attempts to review in brief, the approach to early diagnosis and management with literature review and case examples.

Physis is the weakest structure in the skeleton of a child and a frequent site of an injury or fracture. A physeal fracture presents a unique challenge in the management as the sequalae of such an injury could lead to growth disturbances.

In this review, mainly focussing on traumatic physeal injuries, the authors discuss the applied anatomy, different fracture patterns, clinical assessment and management of physeal fractures in children.

Discussion on acute physeal injuries as well as physeal arrest and approach to its management is presented. Past attempts for treatment of physeal injuries and recent advances in their management is also discussed.

The ideal approach to treat physeal injuries should take into account the location of injury, age of the patient, fracture type and growth potential of the involved physis. Prompt diagnosis and physeal-respecting treatment techniques are important.

Behavior analyst supervisors and their trainees may face challenges fulfilling their responsibilities in the midst of barriers that include competing contingencies, transitions, and interruptions. In this article, we review potential obstacles faced by supervisors in designing effective supervision through site closures and transitions to telepractice as a result of the COVID-19 pandemic. We explore related potential barriers faced by trainees serving clients through public school settings, as well as through insurance-funded agencies in the United States. We review some practical solutions and offer tools for supervisors and trainees to consider at this time. We present a template for trainees to help them develop a personalized applied behavior analysis fieldwork plan for their supervision, a client/family needs assessment, and a corresponding trainee needs assessment to assist with adaptations to supervision and service delivery in an individualized manner.

Type 1 diabetes originates from gene-environment interactions, with increasing incidence over time.

To identify correlates of childhood type 1 diabetes in European countries using an ecological approach. Several environmental variables potentially influencing the onset of type 1 diabetes have been previously evaluated. However, the relationships between epidemiologic data and exposure to toxic airborne molecules are scarcely studied.

We employed an ecological model to explore, in a wide time period (1990-2018), associations between type 1 diabetes incidence in 19 European countries (systematic literature review) and the nationwide production of five widely diffused air pollutants particulate matter < 10 μm (PM10), nitrogen oxides (NO), non-methane volatile organic compounds (VOCs), sulphur oxide (SO

), and ammonia.

Data confirm a raising incidence of type 1 diabetes in 18 out of 19 explored countries. The average difference (last

first report, all countries) was +6.9 × 100000/year, with values uture type 1 diabetes incidence throughout Europe.

Evidence justify further studies to explore better links between long-term air quality and type 1 diabetes onset at the individual level, which should include exposures during pregnancy. In this respect, type 1 diabetes could be, at least in part, a preventable condition. Folinic mw Thus, primary prevention policies acting through a marked abatement of pollutant emissions might attenuate future type 1 diabetes incidence throughout Europe.

The importance of the neuronal microenvironment has been recently highlighted in gut region-specific diabetic enteric neuropathy. Regionally distinct thickening of endothelial basement membrane (BM) of intestinal capillaries supplying the myenteric ganglia coincide with neuronal damage in different intestinal segments. Accelerated synthesis of matrix molecules and reduced degradation of matrix components may also contribute to the imbalance of extracellular matrix dynamics resulting in BM thickening. Among the matrix degrading proteinases, matrix metalloproteinase 9 (MMP9) and its tissue inhibitor (TIMP1) are essential in regulating extracellular matrix remodelling.

To evaluate the intestinal segment-specific effects of diabetes and insulin replacement on ganglionic BM thickness, MMP9 and TIMP1 expression.

Ten weeks after the onset of hyperglycaemia gut segments were taken from the duodenum and ileum of streptozotocin-induced diabetic, insulin-treated diabetic and sex- and age-matched control rats. The der control conditions. In the diabetic ileum, the number of MMP9-indicating gold particles decreased in myenteric ganglia, endothelial cells of capillaries and intestinal smooth muscle cells, however, it remained unchanged in all duodenal compartments. The MMP9/TIMP1 ratio was also decreased in ileal ganglia only. However, a marked segment-specific induction was revealed in MMP9 and TIMP1 at the mRNA levels.

These findings support that the regional decrease in MMP9 expression in myenteric ganglia and their microenvironment may contribute to extracellular matrix accumulation, resulting in a region-specific thickening of ganglionic BM.

Since then, several measures to limit virus transmission have been imposed; among them, home confinement has been the most severe, with drastic changes in the daily routines of the general population. The "stay at home" rule has impaired healthcare service access, and patients with chronic conditions were the most exposed to the negative effects of this limitation. There is strong evidence of the worsening of obesity and diabetes mellitus in children during this period. To overcome these issues, healthcare providers have changed their clinical practice to ensure follow-up visits and medical consultation though the use of telemedicine. Telemedicine, including telephone calls, videocalls, data platforms of shared telemedicine data platforms mitigated the negative effect of pandemic restrictions. Published evidence has documented good metabolic control and weight management outcomes in centers that performed extensive telemedicine services last year during the pandemic.
