Bisphosphonates and Atypical Femur Fractures: Is the Relationship Causal or Casual?

Bisphosphonates (BPs) are a time-tested drug class with multivariate use cases. They are used in pathologies ranging from osteoporosis to Paget's disease, and also help in accelerated fracture healing. They have been used to treat both benign and malignant lesions of the skeletal system since a long time. However, there have been reports of increased incidences of atypical femoral fractures (AFFs) in patients exhibiting chronic use of bisphosphonates in the past years. This has led to the widespread dissuasion of physicians and practitioners from using the drug class. By means of this review of the literature, the authors aim to investigate the relationship between BP use and its association with AFFs. The review focuses on and elucidates the basic pharmacology of BPs and goes on to illustrate the indications of BPs in various pathologies of the musculoskeletal system, further exploring the effects of BPs on the healing of various bony fractures. The authors also explore the incidences of other pathologies, such as osteonecrosis of the jaw and nephropathies associated with BP use, and elaborate on their features. Through this review, the authors have tried to educate and induce critical thinking on the part of clinicians and medical professionals in regard to prescribing BPs to patients that need them, by keeping in mind the risk-reward relationship that accompanies their use.

Management of Eustachian Tube Dysfunction: A Review.

The Eustachian tube is a crucial pneumatic component of the head and neck region and is often neglected as an important site of insidious pathologies. In our literature review, we negotiate the management of eustachian tube dysfunction and explore the various therapeutic and surgical options available at our disposal. We begin by investigating the physiological nature of the eustachian tube and its role in the body's functioning. We also list and elaborate on the various pathologies affecting the Eustachian tube and its associated structures. The review then outlines eustachian tube dysfunction and discusses the pathophysiology involved in the genesis of the condition and its progression. Further, the review explores the tools most commonly used to diagnose or alleviate the condition, including, but not limited to, the Valsalva maneuver, Toynbee maneuver, tympanometry, pressure chamber test, and video nasopharyngoscopy. We also touch on The ETS-7 questionnaire and then on the various surgical interventions that may be used to manipulate the condition. The review also describes conventional tympanostomy and myringotomy, along with more novel techniques such as microwave ablation, laser eustachian tuboplasty, and balloon eustachian tuboplasty. We conclude by establishing the most favorable course of treatment in cases of eustachian tube dysfunction.
