Post Dural Puncture Subdural Hematoma: A Rare Iatrogenic Complication of Neuraxial Anesthesia.

Although post-dural puncture headache is a well-known complication of neuraxial anesthesia, subdural hematoma following epidural injection is a rare but potentially under-recognized complication. The following is the case of a young female patient with no significant past medical history who developed a persistent and severe headache following the introduction of epidural anesthesia for labor induction. Imaging demonstrated multiple small subdural hematomas with findings concerning intracranial hypotension.

Acutely presenting congenital chest lesions: a primer for the radiologist.

Congenital chest lesions encompass several important entities. Without prompt intervention, many of these can culminate in serious complications. Timely and accurate radiologic interpretation of these entities is integral to patient management.

Role of Rituximab in miraculous cessation of ventricular tachycardia in Granulomatosis with polyangiitis: A case report.

Granulomatosis with polyangiitis (GPA) is a rare systemic disorder of unknown aetiology. The histological findings comprise necrotising granulomatous inflammation of small arteries, arterioles, and the capillaries mainly of upper and lower respiratory tract and the kidneys. However, the disease rarely involves the cardiovascular system but may manifest as pericarditis, myocarditis, coronary arteritis, valvular lesions, and severe conduction disorders.

High-gain observer-based nonlinear control scheme for biomechanical sit to stand movement in the presence of sensory feedback delays.

Sit-to-stand movement (STS) is a mundane activity, controlled by the central-nervous-system (CNS) via a complex neurophysiological mechanism that involves coordination of limbs for successful execution. Detailed analysis and accurate simulations of STS task have significant importance in clinical intervention, rehabilitation process, and better design for assistive devices. The CNS controls STS motion by taking inputs from proprioceptors.

Nonlinear postural control paradigm for larger perturbations in the presence of neural delays.

Maintaining balance is an essential skill regulated by the central nervous system (CNS) that helps humans to function effectively. Developing a physiologically motivated computational model of a neural controller with good performance is a central component for a large range of potential applications, such as the development of therapeutic and assistive devices, diagnosis of balance disorders, and designing robotic control systems. In this paper, we characterize the biomechanics of postural control system by considering the musculoskeletal dynamics in the sagittal plane, proprioceptive feedback, and a neural controller.

Obstructive Sleep Apnoea in Pakistan: A Single Tertiary Care Center Experience.

Introduction: Considerable interest has been shown in the field of sleep medicine in recent decades. Obstructive sleep apnoea (OSA) is a common condition that remains neglected in most parts of the world. Data are scarce, if any, when it comes to developing countries.
