A Practical Ambulatory Approach to Atrioventricular Block Secondary to Lyme Carditis.

Lyme carditis (LC) is a potentially reversible cause of complete atrioventricular (AV) dissociation that rarely requires a permanent pacemaker. The time to resolution is variable, sometimes requiring weeks, making a temporary permanent pacemaker (TPPM) a suitable bridge to recovery. We report on a 31-year-old man with serology-confirmed Lyme disease with complete heart block during the peak of the coronavirus disease 2019 pandemic.

Comparison of the major intraoperative and postoperative complications between unilateral and sequential bilateral total knee arthroplasty in a high-volume community hospital.

Background: Total knee arthroplasty (TKA) is a common surgical treatment for arthritis. In the event of bilateral knee symptoms, a patient may elect for bilateral TKA (BTKA) under 1 anesthetic or 2 separate unilateral TKAs (UTKA). Controversy exists in the literature regarding the safety of BTKA versus UTKA.

Understanding the neuropsychiatric consequences associated with significant traumatic brain injury.

Background: Traumatic brain injury (TBI) can give rise to a variety of neuropsychiatric syndromes. The objective of this review is to describe the neurobiological mechanisms that have been proposed to underlie many of these post-TBI syndromes, explore the utility of various investigative modalities and review the mechanisms of treatment available for them.

Methods: Six authors reviewed PubMed and Ovid literature that addressed TBI in the context of the neuropsychiatric sequelae, evaluation and management.
