Simultaneous isolated bilateral patellar fractures are very rare injuries and most often associated with systemic disorders such as hyperparathyroidism, osteoporosis, stress fracture and kidney failure. Isolated bilateral traumatic fracture of patella following an unusual mode of injury is seldomly reported in the literature. We reported such a case following a road traffic accident without any associated injuries or co-morbid condition. The patella on the right side had transverse open fracture which was fixed with two Kirschner wires following tension band principle, and that on the left side sustained upper pole comminution which was treated by partial patellectomy. The patient achieved good outcome： at 6 months he was able to squat and sit cross legged; at one year he obtained nearly normal muscle strength and full range of motion. We discussed the injury mechanism, management and rehabilitation in such a case and reviewed the available literature regarding such a presentation.

Lung cancer is the leading cause of cancer-related mortality worldwide. Non-small cell carcinoma and small cell carcinoma are the main histological subtypes and constitutes around 85% and 15% of all lung cancer respectively. Multimodality treatment plays a key role in the successful management of lung cancer depending upon the histological subtype, stage of disease, and performance status. Imaging modalities play an important role in the diagnosis and accurate staging of the disease, in assessing the response to neoadjuvant therapy, and in the follow-up of the patients. Last decade has witnessed voluminous upsurge in the use of positron emission tomography-computed tomography(PET-CT); role of PET-CT has widened exponentially in the management of lung cancer. The present article reviews the role of 18-fluoro-deoxyglucose PET-CT in the management of non small cell lung cancer with emphasis on staging of the disease and the assessment of response to neoadjuvant therapy based on available literature.

Gastrointestinal stromal tumours(GISTs) are mesen-chymal neoplasms originating in the gastrointestinal tract, usually in the stomach or the small intestine, and rarely elsewhere in the abdomen. The malignant potential of GISTs is variable ranging from small lesions with a benign behaviour to fatal sarcomas. The majo-rity of the tumours stain positively for the CD-117(KIT) and discovered on GIST-1(DOG-1 or anoctamin 1) expression, and they are characterized by the presence of a driver kinase-activating mutation in either KIT or platelet-derived growth factor receptor α. Although surgery is the primary modality of treatment, almost half of the patients have disease recurrence following surgery, which highlights the need for an effective adjuvant therapy. Traditionally, GISTs are considered chemotherapy and radiotherapy resistant. With the advent of targeted therapy(tyrosine kinase inhibitors), there has been a paradigm shift in the management of GISTs in the last decade. We present a comprehensive review of targeted therapy in the management of GISTs.
