The results of surgery for Dupuytren's disease were prospectively assessed to see if there is a correlation between hand function, the degree of deformity and the post-operative result. A total of 42 patients were followed-up for 6 months. The mean flexion deformity was 81 degrees pre-operatively and 32 degrees post-operatively. The mean Sollerman score improved from 71 (out of 80) pre-operatively to 77 post-operatively. There was a significant correlation between the degree of deformity and the Sollerman score, and also between the improvement in deformity after surgery, and the Sollerman score. We conclude that hand function is worsened by increasing deformity in Dupuytren's disease and improved by correction of the deformity.

The use of eight-plates in the proximal tibia for deformity correction and limb-length equalization causes a change in the bony morphology of the tibial plateau in a significant number of patients and the effect is more pronounced in the correction of LLD.

COVID-19 epidemic has swiftly disrupted our day-to-day lives affecting the international trade and movements. Wearing a face mask to protect one's face has become the new normal. In the near future, many public service providers will expect the clients to wear masks appropriately to partake of their services. Therefore, face mask detection has become a critical duty to aid worldwide civilization. This paper provides a simple way to achieve this objective utilising some fundamental Machine Learning tools as TensorFlow, Keras, OpenCV and Scikit-Learn. The suggested technique successfully recognises the face in the image or video and then determines whether or not it has a mask on it. As a surveillance job performer, it can also recognise a face together with a mask in motion as well as in a video. The technique attains excellent accuracy. We investigate optimal parameter values for the Convolutional Neural Network model (CNN) in order to identify the existence of masks accurately without generating over-fitting.

Calcific tendinitis occurs frequently in shoulder and hip region. Its occurrence in elbow joint is frequently misdiagnosed because of its rare incidence and similar clinical presentation with other acute conditions of elbow like trauma, infection and tennis elbow. Characteristic symptoms of this condition are acute onset of pain, tenderness and swelling on the lateral aspect the elbow. Plain Radiograph is the primary modality to distinguish and evaluate this condition. Awareness and familiarity with this condition helps in early diagnosis and avoids unnecessary treatments and biopsy as this condition is self-limited.Keywords: Calcific tendinitis; self-limited; tennis elbow.

The need for fail-slow fault tolerance in modern distributed systems is highlighted by the increasingly reported fail-slow hardware/software components that lead to poor performance system-wide. We argue that fail-slow fault tolerance not only needs new distributed protocol designs, but also desires programming support for implementing and verifying fail-slow fault-tolerant code. Our observation is that the inability of tolerating fail-slow faults in existing distributed systems is often rooted in the implementations and is difficult to understand and debug. We designed the Dependably Fast Library (DepFast) for implementing fail-slow tolerant distributed systems. DepFast provides expressive interfaces for taking control of possible fail-slow points in the program to prevent unexpected slowness propagation once and for all. We use DepFast to implement a distributed replicated state machine (RSM) and show that it can tolerate various types of fail-slow faults that affect existing RSM implementations.

Background:Injury to the underlying structures of the hand carries the potential for serious handicap. To reduce this risk, even the smallest hand injuries require proper medical care.Aims:To assess wound healing, mobility, and the ability to perform normal essential function post-operatively in open hand injuries associated with fracture.Materials and Methods:Thirty patients with 45 metacarpal and phalangeal fractures of the hand were divided into three groups: Group 1 (n = 13) cases with single fractures of hand, excluding thumb; Group 2 (n = 9) cases with multiple fracture of hand, excluding thumb; Group 3 (n = 8) cases with fractures involving thumb and first metacarpal. Tendon injuries were repaired. For fractures, Kirschner wire fixation was done. In two cases with multiple fractures, Joshi's external support system (JESS) fixator was applied. Patients were followed up for 12 weeks.Results:One patient with proximal phalangeal fracture developed extension lag. No stiffness was observed in any of the cases treated by intramedullary Kirschner wire fixation. No non-union or delayed union was observed following cross-wire fixation with two Kirschner wires. Two case of open fracture developed superficial infection. Two patients with multiple fractures developed angulation at fracture site after the Kirschner wires were removed 4 weeks postoperatively, and two cases of multiple fractures developed hypertrophic non-union.Conclusions:Delicate handling of tissues, preservation of gliding planes for tendons, prevention of infection, accurate reduction and fixation, and early and appropriate physiotherapy affect prognosis in case of hand injuries.
