Efficacy of topical gabapentin in women with primary macular amyloidosis: A side-by-side triple-blinded randomized clinical trial. J Cosmet Dermatol 2024; 23:1677-1684. [PMID: 38291677 DOI: 10.1111/jocd.16180] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Revised: 12/08/2023] [Accepted: 12/31/2023] [Indexed: 02/01/2024]
Abstract
BACKGROUND Primary cutaneous macular amyloidosis (PCMA) is a chronic pruritic cutaneous disease characterized by heterogeneous extracellular deposition of amyloid protein in the skin. AIMS This study aimed to evaluate the efficacy of topical 6% gabapentin cream for the treatment of patients with PCMA. MATERIALS AND METHODS In this triple-blind clinical trial, a total of 34 patients, who were diagnosed with PCMA, treated using two different strategies of topical gabapentin as the active group and vehicle cream as the control group. RESULTS Pruritus score reduction in both groups was statistically significant compared with the baseline value (p < 0.001). There was a significant pigmentation score reduction in intervention group compared with control group after 1 month of the study (p < 0.001). The differences of pigmentation score changes between the groups were not significant at month 2 (p = 0.52) and month 3 (p = 0.22). CONCLUSIONS The results of this study suggest that topical gabapentin cream may be effective as a topical agent in the treatment of pruritus associated with PCMA without any significant adverse effects. It is recommended to perform similar studies with a larger sample size and longer duration in both sexes.

Abstract
This review provides an overview of considerations in geriatric dermatopathology. The nuances of specimen collection and reporting in this population, including the importance of obtaining adequate tissue, providing detailed clinical information and ethical considerations surrounding specimen collection will be discussed. The histopathologic changes associated with aging and the morphologic features of common lesions related to photoaging are outlined followed by a discussion of common interpretation pitfalls, specifically entities at risk of overinterpretation and those related to hyper- and hypopigmentation. Finally, the recent literature is reviewed regarding special cases and what this implies for future research both in dermatology and dermatopathology.

Abstract
Dysesthesia is an abnormal sensation in the skin that occurs in the absence of any extraordinary stimulus or other primary cutaneous disorders, excluding any delusions or tactile hallucinations. Clinicians have characterized dysesthesias to include sensations such as burning, tingling, pruritus, allodynia, hyperesthesia, or anesthesia. The etiology and pathogenesis of various generalized dysesthesias is largely unknown, though many dysesthesias have been associated with systemic pathologies including malignancy, infection, autoimmune disorders, and neuropathies. Dermatologists are often the first-line clinicians for patients presenting with such cutaneous findings, thus it is crucial for these physicians to be able to methodically work-up generalized dysesthesias to build a working differential diagnosis, follow up with key labs and/or imaging, and offer patients evidence-based treatment to relieve their symptoms. This broad literature review is an attempt to centralize key studies, cases, and series to help guide dermatologists in their assessment and evaluation of complaints of abnormal cutaneous sensations.

Abstract
Dysesthesia is an abnormal sensation typically described as tingling, burning, or itching. Dysesthesia may occur in the presence or absence of causative dermatologic or medical pathology. Sensory abnormalities have been well documented in patients suffering from Alzheimer's disease (AD), though reported abnormalities typically affect the olfactory, visual, and auditory systems. Research describing dysesthetic symptoms in AD is scarce. Major depressive disorder (MDD) is another phenomenon commonly associated with AD, though depressive symptoms are frequently masked by cognitive deficits. Less attention has been given to the reverse of this relationship, in which MDD masks the symptoms of AD. Here, we present a case of undiagnosed AD in a geriatric patient presenting with primary complaints of depression and dysesthesia. We then discuss the pathophysiology of dysesthesia, MDD, and AD, as well as how these entities may interact in a single patient. Lastly, we emphasize the importance of thorough history-taking and multi-specialty collaboration in the care of older adults.

Abstract
PURPOSE PUVA phototherapy is indicated for various dermatological conditions. Adverse events due to PUVA phototherapy are seen in a sizable number of patients and can result in therapy cessation. This review will focus on PUVA pricks, an adverse event first reported by Tegner in 1979. METHODS Articles were retrieved from PubMed starting from January 1979 until February 2021 yielding 1228 unique articles. Articles were included when they described individual patient characteristics, and patients were treated with PUVA therapy. RESULTS After screening, 33 patients were extracted from 9 articles, published between 1979 and 2005. CONCLUSION PUVA pricks are paroxysmal episodes of burning or prickling pain, akin to peripheral neuropathy of the unmyelinated C-fibers. Increased excitability of TRPV1 and TRPA1 channels while under PUVA therapy might be a contributing factor. Effective topical treatment options for PUVA pricks are capsaicin 8% cream, urea 4%, or petrolatum emollients. Antiepileptics such as phenytoin, clonazepam, and gabapentin are acceptable oral treatment options. A possible role of N-acetylcysteine in the prevention of PUVA pricks is discussed, though further research is required.

Abstract
Sensitive scalp is sensitive skin located on the scalp. Sensitivity is considered primary in the absence of an associated scalp disorder and secondary when caused by conditions such as psoriasis, seborrheic dermatitis, and atopic dermatitis. The clinical manifestations of primary sensitive scalp are subjective. Common presenting symptoms are burning, itching, trichodynia, and dysesthesia, often coinciding with hair loss. Clinically, the skin appears normal or red. An objective diagnosis based on laboratory or histologic findings is not possible. Triggers may be endogenous (e.g., stress and emotional or psychopathological disturbances) or exogeneous (e.g., topical products and cosmetics). Treatment must be individualized. Options include pimecrolimus, hydration with hyaluronic acid, and mesotherapy with plasma rich in growth factors.

Abstract
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.

Abstract
Scalp dysesthesia is an abnormal sensation of the scalp in the absence of cutaneous disease. It is characterized by a burning and/or itching sensation and can be related to a variety of neurogenic or psychogenic causes. This condition is extremely bothersome and is also common- especially amongst the geriatric population, in women, in patients with diabetes mellitus and patients with psychiatric history. However, despite its prevalence in many populations, there is limited data about its causes and characteristics. Given its limited cutaneous manifestations it is also easily misdiagnosed and an underrecognized cause of scalp pruritus in the dermatological community. Therefore, education on scalp dysesthesia is paramount to helping physicians identify and provide appropriate treatment for these patients. This review focuses predominately on the neurogenic causes (with a brief review of psychogenic itch) of scalp dysesthesia and the therapeutics that have been found to be effective for this condition. Neurogenic causes of scalp dysesthesia occur with damage to the central or peripheral pathways of itch sensation, resulting in modification and heightened sensitivity of nerves that result in abnormal sensations in the absence of or out of proportion to external stimuli. A comprehensive review of etiologies is provided here, ranging from lesions to the central nervous system caused by cervical spine disease, trigeminal trophic syndrome, tumor, stroke, and multiple sclerosis, to small fiber neuropathies caused by diabetes, brow lifts, keloid and burn scarring. Recently, there have also been reports of scalp dysesthesias associated with post-infectious COVID-19. Treatment options tailored towards disease severity and different causes of disease will also be discussed. By elucidating the different mechanisms and therapeutic treatments of scalp dysesthesia, we hope to provide clinicians with the tools to identify and treat this condition as well as encourage further research into its etiologies and therapeutics.

Abstract
Scalp dysaesthesia, considered a variant of the cutaneous dysaesthesia syndrome, is characterized by chronic sensory symptoms, including pruritus, pain, burning and stinging in a well‐defined location, without objective findings. Its aetiology is not well elucidated and treatment options are limited, thus it can be challenging and frustrating for both patient and physician. It can be associated with lichen simplex chronicus. In this paper, we review the literature on the pathogenetic factors, diagnostic methods and therapeutic options in the management of scalp dysaesthesia. Dissociation, cervical spine disease and muscle tension seem to be the most important pathogenetic factors. Trichoscopy, reflectance confocal microscopy and biopsy are all helpful for the diagnosis of the disease. Therapies include high‐potency topical or intralesional corticosteroids, capsaicin and topical anaesthetics, sedative antihistamines, tricyclic antidepressants, transcutaneous electric nerve stimulation, botulinum toxin and vitamin B12.

Abstract
Neuropathic itch occurs due to damage of neurons of the peripheral or central nervous system. Several entities, including metabolic, neurodegenerative, orthopedic, infectious, autoimmune, malignant, and iatrogenic conditions, may affect the somatosensory system and induce neuropathic itch. Due to the complex nature of neuropathic itch, particularly concerning its clinical presentation and possible etiological factors, diagnostic work-up of this condition is challenging. A detailed medical history, especially in regard to the itch, and a comprehensive physical examination are relevant to detect characteristic signs and symptoms of neuropathic itch and to rule out other possible causes for chronic itch. Complementary diagnostic exams, especially laboratory tests, determination of the intraepidermal nerve fiber density via a skin biopsy and radiological examinations may be indicated to confirm the diagnosis of neuropathic itch and to identify underlying etiological factors. Functional assessments such as quantitative sensory testing, nerve conduction studies, evoked potentials, or microneurography may be considered in particular cases. This review article provides a comprehensive overview of the diagnostic work-up recommended for patients with neuropathic itch.

Abstract
BACKGROUND Notalgia paresthetica (NP) is a neuropathic itching condition unilaterally localized in the midscapular area. It is a common but an underdiagnosed disease, and only a few studies investigating NP etiology with a limited number of patients have been reported in the literature. OBJECTIVE We aimed to evaluate the demographic, clinical, histopathological, neurological, and radiological findings of NP patients and investigate correlations between them and symptoms of NP to elucidate the etiology of NP. METHODS One hundred and seventeen consecutive patients diagnosed with NP were included and assessed in a multidisciplinary and prospective manner. We recorded demographic and clinical data and obtained a skin biopsy from the pruritic or hyperpigmented region. Pruritus severity was assessed by visual analogue scale (VAS). All patients were evaluated neurologically with magnetic resonance imaging. RESULTS The mean age of the patients was 47.08 ± 12.28 years. The disease was more common in females (87.2%). Statistical analysis revealed that VAS scores were independent of the age, gender, and skin type of the patient. We found no significant difference in VAS scores between NP patients with or without comorbidities. Vertebral pathologies detected by MRI and amyloid deposition revealed in histopathology were not among the main factors affecting VAS scores. STUDY LIMITATION Since consecutive patients enrolled into the study, we could not include equal number of male and female patients. CONCLUSION We found no correlation between symptom severity and findings from neurological and histopathological evaluations. Further microneurological studies should be carried out to elucidate the etiology of NP.

Abstract
Paroxysmal symptoms are well-recognized manifestations of multiple sclerosis (MS). These are characterized by multiple, brief, sudden onset, and stereotyped episodes. They manifest as motor, sensory, visual, brainstem, and autonomic symptoms. When occurring in the setting of an established MS, the diagnosis is relatively straightforward. Conversely, the diagnosis is significantly more challenging when they occur as the initial manifestation of MS.

Abstract
This paper describes two clinical cases of a rare auto-destructive hair pathology trichoteiromania. In the literature a few cases of trichoteiromania are described, it leads to non-cicatricial hair loss as a result of their rubbing and is characterized by splitting and damaging of the hair shaft.
The clinical picture features, trichoscopic signs of the disease are presented: foci of baldness in the scalp, hair shafts not more than 1.5 cm long, curved, scaling as a result of scratching the skin. Trichoscopic features: broken hair up to 1,5 сm length, splitting of the distal end of the hair shaft (trichoptilosis), scaling.
The data on the differential diagnosis of the disease with other hair pathologies, the possible symptomatic, psychotherapeutic, psychopharmacological treatment of trichoiteromania are presented.
These clinical cases are of interest in connection with rare descriptions in the literature, the importance of trichoscopy in the differential diagnosis of alopecia, the possibility of interaction between a dermatologist and a psychiatrist, a psychotherapist are indicated.

Abstract
Patients with psychocutaneous disorders often refuse psychiatric intervention in their first consultations, leaving initial management to the dermatologist. The use of psychotropic agents in dermatological practice, represented by antidepressants, antipsychotics, anxiolytics, and mood stabilizers, should be indicated so that patients receive the most suitable treatment rapidly. It is important for dermatologists to be familiar with the most commonly used drugs for the best management of psychiatric symptoms associated with dermatoses, as well as to manage dermatologic symptoms triggered by psychiatric disorders.

Abstract
Notalgia paresthetica is a rarely reported T2-T6 sensory neuropathy whose etiology and treatment are not fully established. Although it is believed to be common in dermatological practice, it remains underrecognized, underdiagnosed, and therefore underreported. This case-report provides a physical medicine and rehabilitation perspective on notalgia paresthetica diagnosis and treatment. This article presents a case report of a 39-yr-old woman with pain, pruritus, and a hyperpigmented area in the right dorsal infra scapular region. The diagnosis of notalgia paresthetica was established. She was successfully treated with topical anesthetics, postural corrective exercises, scapular muscle strengthening, and pectoral muscle stretching. In this context, different treatment options were reviewed. A small set of pharmacological and nonpharmacological techniques were identified. Several of these modalities belong to the physical medicine and rehabilitation field of action.

Abstract
Scalp dysesthesia may be underrecognized but is an important condition which requires special management strategies. Through our case series of four patients, we have noted that patients were frequently misdiagnosed with seborrheic dermatitis and failed standard treatment. However, patients did benefit from low doses of oral pregabalin and a topical compound of amitriptyline, lidocaine and ketamine. Oral antihistamines and topical corticosteroids did not work sufficiently on their own but added value when used in conjunction with analgesic agents. Our experience and published work also suggest the association of cervical spinal changes, psychiatric disorders, and other environmental and habitual factors.

Abstract
- Notalgia paresthetica is a common, although under-recognized condition characterized by localized chronic pruritus in the upper back, most often affecting middle-aged women. Apart from pruritus, patients may present with a burning or cold sensation, tingling, surface numbness, tenderness and foreign body sensation. Additionally, patients often present with hyperpigmented skin at the site of symptoms. The etiology of this condition is still poorly understood, although a number of hypotheses have been described. It is widely accepted that notalgia paresthetica is a sensory neuropathy caused by alteration and damage to posterior rami of thoracic spinal nerves T2 through T6. To date, no well-defined treatment has been found, although many treatment modalities have been reported with varying success, usually providing only temporary relief.

Abstract
Musculoskeletal (MSK) conditions are growing in prevalence. Ultrasound (US) is increasingly used for managing MSK conditions due to its low cost and ability to provide real-time image guidance during therapeutic interventions. As MSK US becomes more widespread, familiarity and comfort with US-guided interventions will become increasingly important. This article focuses on general concepts regarding therapeutic US-guided injections of corticosteroids and platelet-rich plasma and highlights several of the US-guided procedures commonly performed, involving the pelvis and lower extremity.

Abstract
Unlike conventional itch, neuropathic itch develops in normal skin from excess peripheral firing or dampened central inhibition of itch pathway neurons. Neuropathic itch is a symptom of the same central and peripheral nervous system disorders that cause neuropathic pain, such as sensory polyneuropathy, radiculopathy, herpes zoster, stroke, or multiple sclerosis, and lesion location affects symptoms more than aetiology. The causes of neuropathic itch are heterogeneous, and thus diagnosis is based primarily on recognising characteristic, disease-specific clinical presentations. However, the diagnosis of neuropathic itch is challenging, different subforms exist (eg, focal vs widespread, peripheral vs central), and the mechanisms of neuropathic itch are poorly understood, resulting in reduced treatment availability. Currently available strategies include treating or preventing causal diseases, such as diabetes or herpes zoster, and topical or systemic medications that calm excess neuronal firing. Discovery of itch mediators such as gastrin releasing peptide, receptors (eg, neurokinin-1), and pathways (eg, Janus kinases) might encourage much needed new research into targeted treatments of neuropathic itch.

Abstract
A good understanding of cutaneous nerve entrapment syndromes is important for physicians to provide early and accurate diagnosis and treatment. These syndromes have traditionally been managed with analgesics, antidepressants or antiepileptic medication but this approach is often inadequate and causes frequent adverse medication effects. With early diagnosis and treatment, many nerve entrapment syndromes can be successfully managed with physical, non-pharmacological approaches including stretches, exercises and physiotherapy.

Abstract
Notalgia paresthetica, a neurosensory syndrome that typically occurs on the upper back, has multiple clinical symptoms with variable degrees of expression in each individual afflicted with the condition. The involved site is usually hyperpigmented and is associated with burning, coldness, hypoesthesia, increased pain, pruritus and/or tingling. In the affected area, the number of nerve fibers may be increased and the cutaneous sensory nerves are altered secondary to localized impingement, central injury, or both. Although multiple therapeutic approaches for notalgia paresthetica have been described, none specifically address the essential pathogenesis of the condition—the altered cutaneous nerves. Cryolipolysis is a well-tolerated nonsurgical technique to reduce the subcutaneous fat layer. Selective apoptosis of adipocytes occurs since the lipid-rich fat cells are more susceptible to cold injury than the surrounding water-rich cells. Not only a marked decrease in pain sensitivity but also a sustained reduction in the density of myelinated and unmyelinated cutaneous nerves has been observed in cryolipolysis-treated skin. Therefore, cryolipolysis is a logical approach to the treatment of notalgia paresthetica. One or more cryolipolysis treatments may be necessary for complete or partial resolution of the individual’s notalgia paresthetica-related cutaneous symptoms. In conclusion, evaluation of cryolipolysis as a noninvasive treatment of patients with notalgia paresthetica is warranted.

Abstract
Objective Vitiligo usually presented as asymptomatic depigmented macules and patches. Little is known regarding itch in vitiligo. This study aimed to evaluate the prevalence and characteristics of itch in vitiligo patients. Patients and Methods A cross-sectional study was conducted on vitiligo patients. Itch character and intensity were determined through questionnaires. Evaluation was also made by dermatologists to define vitiligo subtype, body surface area, Koebner phenomenon (KP), and so on. Data were assessed by computer software. Results were considered statistically significant if p < 0.05. Results Among 402 patients, itch on vitiliginous lesion presented in 20.2%. Prevalence of itch was most common in focal vitiligo (29.4%), followed by segmental vitiligo (20.3%) and nonsegmental vitiligo (19.6%), respectively. Tingling sensation was the most common itch-related symptom (82.7%). The median itch intensity is 5 by 10-point visual analog scale. Daily activity and sleep disturbance were observed in 60.5% and 39.5% of patients who experience itch. Itch occurred approximately 3 days prior to the development of lesions in 48.1% of patients. Thirty-two patients (78.1%) with both itch and KP type IIb had active disease. Conclusions Itch in vitiligo is not uncommon. The presence of itch with KP type IIb may warrant the active vitiligo.

Abstract
Polymorphous light eruption (PLE) is the commonest immuno-mediated photodermatosis. It occurs after solar or artificial UV-light exposure and affects only the sun-exposed areas with preference of the V-area of the chest, of arms and forearms, legs, upper part of the back, and rarely the face. The lesions are itching or burning, and vary morphologically from erythema to papules, vesico-papules and occasionally blisters, plaques, sometimes erythema multiforme-like, insect bite-like wheals and purpura. The clinical manifestations befall within a few hours to days from light exposure, last a few days, and subside in about a week without sequelae. Its diagnosis is based on history, morphology and phototests. PLE is considered as a delayed hypersensitivity response to newly UV induced, but still unidentified, antigen(s). Usually, MED is normal, but the provocative phototests with UVA or UVB reproduce the spontaneous lesions in about 50% of the patients. Broad spectrum sunscreens and antioxidants, photohardening with PUVA or narrow band UVB may be beneficial to prevent the disease. Therapy is based mainly on topical or systemic corticosteroids.

Abstract
Dermatologists face a wide range of pain control challenges in daily practice, from the transient pain of dermatologic surgery to the persistent pain that plagues some chronic dermatologic conditions. Although the pathophysiology of pain is well described and the profound impact of dermatological pain on patients' quality of life is well appreciated, there is an identified need for clear therapeutic plans for providing symptomatic pain relief of common painful dermatoses. In this paper, we will review and clearly outline approaches to pain management of a number of common painful dermatoses such as herpes zoster and post-herpetic neuralgia, ulcers, oral dermatoses, dysesthesias, and many others.

Abstract
OBJECTIVE Peripheral nerves are well seen using ultrasound (US) imaging, making US an ideal modality for image-guided nerve injections. This article provides a technical guide for common upper and lower extremity peripheral nerve injections, including the median, ulnar, and radial nerves in the upper extremity and the lateral femoral cutaneous, sciatic, common peroneal, tibial, and sural nerves in the lower extremity. CONCLUSION US is an effective modality for use in common upper and lower extremity peripheral nerve injections. With correct technique, peripheral nerve injections can be performed safely and are useful for both diagnostic evaluation of and therapy for peripheral neuropathy.
