Artificial Intelligence-Based Teleopthalmology Application for Diagnosis of Diabetics Retinopathy.

Diabetic Retinopathy (DR) is one of the leading causes of blindness for people who have diabetes in the world. However, early detection of this disease can essentially decrease its effects on the patient. The recent breakthroughs in technologies, including the use of smart health systems based on Artificial intelligence, IoT and Blockchain are trying to improve the early diagnosis and treatment of diabetic retinopathy. In this study, we presented an AI-based smart teleopthalmology application for diagnosis of diabetic retinopathy. The app has the ability to facilitate the analyses of eye fundus images via deep learning from the Kaggle database using Tensor Flow mathematical library. The app would be useful in promoting mHealth and timely treatment of diabetic retinopathy by clinicians. With the AI-based application presented in this paper, patients can easily get supports and physicians and researchers can also mine or predict data on diabetic retinopathy and reports generated could assist doctors to determine the level of severity of the disease among the people.

Management of Chronic Non-healing Wounds by Hirudotherapy.

A chronic wound is a wound that does not heal in an orderly set of stages and in a predictable amount of time or wounds that do not heal within three months are often considered chronic. Chronic wounds often remain in the inflammatory stage for too long and may never heal or may take years. Chronic wound patients often report pain as dominant in their lives. Persistent pain is the main problem for patients with chronic ulcers. Many wounds pose no challenge to the body's innate ability to heal; some wounds, however, may not heal easily either because of the severity of the wounds themselves or because of the poor state of health of the individual. Any wound that does not heal within a few weeks should be examined by a healthcare professional because it might be infected, might reflect an underlying disease.

Vertical axis patellar dislocation with ipsilateral femoral fracture: use of a closed percutaneous technique for reduction of the dislocation.

Intra-articular vertical axis dislocations are rare injuries, which mostly occur after blunt trauma. In this type of dislocation, the patella rotates along its vertical axis, bringing the articular surface to face medially or laterally. A 13-year-old boy sustained an intra-articular lateral patellar dislocation with a 90 degrees vertical axis medial rotation, which resulted in the articular surface facing laterally, the medial edge of the patella pointing posteriorly, and the lateral edge of the patella pointing anteriorly. As a result, the patella was wedged between the medial and lateral femoral condyles. He also sustained an ipsilateral closed distal femoral shaft fracture. Closed reduction of the dislocation was not successful. Subsequently an A-O reduction clamp was used percutaneously to reduce the patellar dislocation. The femoral fracture was then stabilized by internal fixation using a dynamic compression plate. Isolated vertical and horizontal dislocations have been previously described, but the presence of an ipsilateral femoral shaft fracture makes this a unique case. The percutaneous method used for reduction of the patella has not been previously described. A focused review of the literature, pathoanatomy, and methods of treatment of this condition are presented.

Congenital aplasia or hypoplasia of extensor tendons of the hand--a case report and review of the literature.

An 8-year-old boy presented with inability to extend his fingers. Examination revealed congenital hypoplasia of the extensor tendons. He was treated with tendon transfers. We present a review of the literature and management of such cases.

The reliability of the American Knee Society Score.

We have investigated the reliability of the American Knee Society Score (AKS), a widely used functional outcome score for knee arthroplasty. 29 subjects were assessed in random order by 6 observers, each patient seen twice by each observer. The interobserver reference intervals were 16 points for the Knee Score (0-100 points) and 21 points for the Function Score (0-100 points). The intraobserver reference intervals were smaller, 11 points and 13 points for the Knee Score and the Function Score, respectively. The presence of arthritis in other joints and general debility did not affect the reliability of the scores. The more experienced observers had greater intraobserver reproducibility. Notably, we found moderate agreement between observers in the subjective variables, while the objective variables produced lower levels of agreement. The high inter- and intraobserver variations of the AKS makes estimation of score change questionable. Reliable use of the AKS would necessitate repeated evaluation by an experienced observer.
