Five Times Reactivation of COVID-19 in a Patient with Thymoma.

Background: The possibility of recurrence in COVID-19 is very rare and hence mostly underdiagnosed. In the face of pandemic, this can lead to circulation of the virus like a hidden iceberg. Better understanding about this topic can improve our knowledge of the COVID-19 pathogenesis and ways to control the transmission.

Role of anti-oxidant (vitamin-C) in post-operative pain relief in foot and ankle trauma surgery: A prospective randomized trial.

Background: Post-operative pain may adversely affect a patient's quality of life. Studies have shown that vitamin C, being an anti-oxidant and neuro-modulating agent, can help to reduce pain in a variety of clinical settings. The objective of this randomized controlled trial was to assess the effectiveness of vitamin C in reducing post-operative pain, analgesia requirements and improving functional outcome.

Comparison of Plantar Fasciitis Injected With Platelet-Rich Plasma vs Corticosteroids.

Background: Plantar fasciitis is one of the most common causes of heel pain. This prospective study compared the efficacy of local injection of corticosteroids vs platelet-rich plasma (PRP) in the treatment of plantar fasciitis.

Methods: Patients were randomly allocated into 2 groups of 40 each (group A and group B).

Obturator Dislocation of Hip with Ipsilateral Fracture Neck Femur-A Case Report.

Introduction: Traumatic dislocation of the hip with ipsilateral fracture neck femur is a rare injury because of the different mechanism of both these injuries. The management of such injuries is a challenge as the chances of nonunion and avascular necrosis of femoral head are very high with fixation methods. We report a case of obturator dislocation of the hip with ipsilateral fracture neck of the femur which was treated with uncemented total hip replacement.

Analysis of risk factors for failure of arthroscopic ankle fusion in a series of 52 ankles.

Background: The purpose of this retrospective study is to analyze the effect of different variables on union rate and functional outcome in patients who underwent arthroscopic ankle fusion for end-stage arthritis of ankle.

Methods: Clinical records and radiographs were reviewed to evaluate the variables that could predispose patients to non-union and poor functional outcome. Union and functional outcomes were correlated with different variables.

Electronic transport properties of BN sheet on adsorption of ammonia (NH3) gas.

We report the detection of ammonia gas through electronic and transport properties analysis of boron nitride sheet. The density functional theory (DFT) based ab initio approach has been used to calculate the electronic and transport properties of BN sheet in presence of ammonia gas. Analysis confirms that the band gap of the sheet increases due to presence of ammonia.

Hoffa's fracture - lateral meniscus obstructing the fracture reduction - a case report.

Hoffa's fracture is a coronal fracture of the posterior femoral condyle and is an unusual injury. It can be easily missed on plain radiographs. There is no dearth of literature on Hoffa's fracture, its various presentations, management and rehabilitation principles.

Ligamentous advancement for the treatment of subacute syndesmotic injuries. Report of a new technique in 5 cases.

Background: Integrity and optimum functioning of the syndesmotic ligament complex is of paramount importance for stability of the ankle joint during various ankle movements. Persistent widening and chronic isolated instability of the distal tibio-fibular syndesmosis leads to poor functional outcome and the development of osteoarthritis. In subacute total ruptures the focus of treatment is to restore the normal anatomy by repair of the ruptured ligament and to protect the reconstruction for a period of time.

Ipsilateral Radial Head Dislocation and Radial Shaft Fracture in a Child-A Case Report.

Introduction: Traumatic dislocation of the radial head in paediatric population is a well described injury, it is usually associated with an injury to the ulna in the Monteggia lesion (1), but can occur as an isolated injury also (2,3).

Case Report: A 4.5 year old girl presented to emergency department with her right upper limb held in pronation and flexion following isolated closed injury.

Ab-initio study of structural, electronic, and transport properties of zigzag GaP nanotubes.

Stability and electronic properties of zigzag (3 ≤ n ≤ 16) gallium phosphide nanotubes (GaP NTs) have been analyzed by employing a systematic ab-intio approach based on density functional theory using generalized gradient approximation with revised Perdew Burke Ernzerhoff type parameterization. Diameter dependence of bond length, buckling, binding energy, and band gap has been investigated and the analysis shows that the bond length and buckling decreases with increasing diameter of the tube, highest binding energy of (16, 0) confirms this as the most stable amongst all the NTs taken into consideration. The present GaP NTs shows direct band gap and it increases with diameter of the tubes.

Efficacy of intra-articular tranexamic acid in blood loss reduction following primary unilateral total knee arthroplasty.

Purpose: The surgical stress of total knee arthroplasty (TKA) procedure and the application of intra-operative pneumatic thigh tourniquet increases local fibrinolytic activity, which contributes significantly to post-operative blood loss. Tranexamic acid, an antifibrinolytic drug, is commonly used to control post-operative blood loss. The recommended mode of administration of tranexamic acid is either oral or intravenous.

Treatment of Osteoporosis with Antiresoptive agent, Alendronate - warrants careful follow-up.

Introduction: Alendronate is the most popular bisphosphonate used to prevent fragility fracture of postmenopausal osteoporosis. There is common belief among physicians that Alendronates are very safe without many side effects and they continue it for long time. Recent papers have shown that, some patients who are on this drug from a long period suffered a rare type of fracture.

An unusual presentation of a simple bone cyst in the scapula.

A 38-year-old man presented with pain in the left shoulder following a fall. A rotator cuff tear was suspected but roentgenograms revealed a lytic, expanded, multiseptate lesion of the scapula adjacent to glenoid. This was compatible with a giant cell tumor, aneurysmal bone cyst or simple bone cyst.

Unusual presentation of altered bone metabolism with long-term antiepileptic therapy: pathological fracture of neck of femur due to brown tumor at calcer.

The antiepileptic drugs are known to alter the bone metabolism and result in various range of pathological conditions (osteoporosis, osteomalacia, vitamin D deficiency, secondary hyperparathyroidism). These clinical conditions developed either due to direct effect of these therapeutic agents on bone or due to alteration in the homeostasis of other regulators of bone metabolism like serum calcium, vitamin D, and parathyroid hormone. Long-term therapy with antiepileptic agents results in higher incidence of pathological fracture, which is a consequence of either osteoporotic or osteomalasic (secondary to vitamin D deficiency) changes in bone produced by these drugs.
