ABSTRACT
Lumbar sympathetic blocks (LSBs) have long been used for the treatment of chronic lower extremity pain and for conditions such as complex regional pain syndrome (CRPS). With a better understanding of the autonomic nervous system and its function, these blocks have grown in their utility. Through this growth, however, our understanding of sympathetic-mediated pain is still vaguely understood. Here, we present a case of a patient who underwent a point-of-care ultrasound (POCUS) before and after an LSB, and we were able to show significant dilation of the posterior tibial artery (PTA) following the block. We propose that this arterial dilation plays a mechanistic role in providing pain relief to patients who undergo LSB. This increased blood flow can not only enhance healing properties to surrounding tissues but also allow for nitric oxide to play potential regulatory roles in pain pathways. Here, we also review potential mechanisms of the amelioration of sympathetic-mediated pain as well as the potential utilization of LSBs and neuromodulation in treating visceral pathologies through a better understanding of visceral somatic relationships.
ABSTRACT
Myasthenia gravis (MG) is a rare disorder that most commonly presents with ocular symptoms. Despite the highly sensitive blood work that can be used to diagnose the disease, it is frequently misdiagnosed until the disease becomes systemic. Literature, however, shows that those who begin treatment with acetylcholinesterase inhibitors before systemic presentation have a better prognosis. We discuss the case of a patient who presented to the clinic with a chief complaint of diplopia that was subsequently referred to ophthalmology. It was not until lab work was done by a subspecialist that the diagnosis of MG was made. The patient quickly responded to an acetylcholinesterase inhibitor and has since had a great prognosis. Here, we are advocating for the inclusion of routine lab work in the evaluation of patients who present to the primary care setting with diplopia in the absence of red flag symptoms. This approach aids in deciphering the potential involvement of MG in diplopia or ptosis. While such symptoms justify referral to ophthalmology, logistical challenges often hinder a prompt evaluation. Early diagnosis with the incorporation of routine lab work offers the potential to expedite the diagnosis of a rare disease. In doing so, providers can improve prognosis and potentially mitigate additive medical consultations.
ABSTRACT
Idiopathic brachial neuritis is an uncommon disorder that predominately affects the superior and middle trunks of the brachial plexus. Severe throbbing and aching shoulder pain is initially present for a period of days to weeks, followed by severe weakness and atrophy that can develop for an extended period of months to years. There are currently no known treatments for brachial neuritis, with the standard of care consisting of analgesics and corticosteroids, which typically provide minimal to no benefit in most cases. In this case, we will present a case of a patient who was diagnosed with idiopathic brachial neuritis and underwent an interlaminar epidural steroid injection (ESI) for treatment. Following treatment with the ESI, the patient had a subsequent resolution of symptoms. This case underscores the value of early recognition for the diagnosis of brachial neuritis and the utility of an ESI as a treatment option, thus preventing long-term pathological sequalae. To our knowledge, this is the first known reported case to have successfully cured brachial neuritis.
