Management of Pain Associated with Selected Conditions in Dermatology

Neuropathic Pain Masquerading as Dermatologic Symptoms: A Case of Misleading Cutaneous Presentation

Neuropathic pain presenting as dermatologic symptoms can occur when damaged or dysfunctional nerves manifest with symptoms that resemble skin-related conditions. We present a case of a 62-year-old male who presented with burning pain and redness in the perineum and gluteal cleft. Initially, the patient was treated for dermatologic symptoms, resulting in the resolution of erythema. However, the pain persisted, prompting a neurologic workup. Despite the improvement of skin symptoms, the patient's pain persisted, prompting a neurological workup. Diagnostic imaging revealed significant degenerative changes in the lumbar spine, supporting a neuropathic etiology. This case highlights the importance of considering neurologic disorders in dermatologic practice, especially when cutaneous symptoms persist despite appropriate dermatological treatments.

Management of pain in the inpatient and non-surgical outpatient dermatology settings: A narrative review

Pain is frequently encountered in dermatology practice, which impairs the activities of daily living, adds to psychological morbidity, and therefore compromises the quality of life. It ranges from mild to severe in intensity across various dermatoses and requires prompt addressal and treatment. Diseases such as extensive pemphigus vulgaris and Stevens-Johnson syndrome are especially painful and require a multidisciplinary approach with the involvement of a pain specialist in their management. The main pathogenic types of pain include visceral nociceptive, somatic nociceptive, and neuropathic types, the latter two being most relevant in dermatological disorders. Somatic nociceptive pain is often seen in patients of Stevens-Johnson syndrome/ Toxic epidermal necrolysis, epidermolysis bullosa, pemphigus vulgaris, erythema nodosum, and hidradenitis suppurativa, while neuropathic pain is part of the disease process in dermatoses like leprosy, herpes zoster, and dysesthesia syndromes. Therapeutic approaches to pain management include the use of non-opioids (acetaminophen, non-steroidal anti-inflammatory agents), opioids, and non-pharmacological therapies, along with appropriate management of the underlying dermatosis. World Health Organisation (WHO) analgesic ladder remains the most commonly employed guideline for the management of pain, although treatment needs individualisation depending on the nature and severity of pain (acute/chronic), type of dermatosis, and patient factors. There is a paucity of literature pertaining to pain management in dermatology and this topic is often neglected due to a lack of awareness and knowledge of the topic. The present review aims to discuss the pain pathway, various painful conditions in the setting of medical dermatology practice, and their management along with relevant pharmacology of the commonly used analgesics.

Dermatological Conditions Inducing Acute and Chronic Pain

Pain is a common condition in dermatology. The aim of this review is to analyse the characteristics of pain in dermatology. Some skin diseases are conventionally known to cause pain; e.g. ulcers, pyoderma gangrenosum and herpes zoster. Common dermatoses, such as psoriasis or atopic dermatitis, can also cause significant pain. Some conditions are characterized by neuropathic pain and/or pruritus, without visible primary lesions: e.g. the neurocutaneous diseases, including small fibre neuropathies. Patients often fear pain in skin surgery; however, surgical procedures are rather well tolerated and any pain is mainly due to administration of local anaesthetic. Some therapies may also be uncomfortable for the patient, such as photodynamic therapy or aesthetic procedures. Thus, pain in dermatology is common, and its aetiology and characteristics are very varied. Knowledge of the different situations that cause pain will enable dermatologists to propose suitable analgesic solutions.

Dermatologists are increasing their use of non-opioid pain medications faster than opioids

INTRODUCTION

There is a lack of consensus in the literature on how and when dermatologists should prescribe pain medications. As there is an ongoing opioid abuse epidemic driven by prescription opioids, it is important for all fields to investigate their own prescribing patterns.

METHODS

We analyzed the National Ambulatory Medical Care Survey from 2007 to 2016 to assess the usage of systemic pain medications amongst dermatologists.

RESULTS

There were 16,777 total visits with dermatologists which represents 368 (95% confidence interval 363, 373) million estimated visits. Opioids were used at 1.4% (1.3, 1.6) of visits. As relative proportions, opioids were 35.6 (31.7, 39.6) of all systemic pain medication and non-opioids were 64.4% (53.8, 74.9). The use of opioid (p=.01 [odds ratio 1.08 (1.02, 1.14)]) and non-opioid (p<.001 [odds ratio 1.12 (1.07, 1.17)]) medications increased over the study interval.

CONCLUSION

Pain medications were used at a relatively small proportion of visits with dermatologists. Opioids were nearly half of all pain medications used. The use of opioids and non-opioids rose over the study interval, however, non-opioids rose at a faster rate. The faster rise of non-opioids may indicate that dermatologists are making an effort to use medications with less potential for abuse.
