Abstract:Purpose: To describe a case of cocaine-induced midline destructive lesions (CIMDL) associated with ocular autoimmune disease. Methods: Observational case report. Results: A 45-year-old man with history of chronic osteolytic sinusitis due to cocaine abuse presented with sudden vision loss in right eye. Ophthalmic examination revealed fixed right mydriasis with extraocular movements limitation and optic disc swelling. Computed tomography showed an orbital infiltrating mass. The diagnosis of orbital-apex syndrome… Show more
“…Consequently, adverse effects within the nasal tract from intense local vasoconstriction are common, and long-term abuse can potentially lead to chronic osteolytic sinusitis, mucoperichondrial ischemia, necrosis, nasal septum perforation, and saddle nose deformity. [14][15][16][17][18] Although CIMDL occurs in only a small minority of cocaine users, it has been well documented in the literature; pathogenesis is believed to involve inflammatory, infective, proapoptotic, and autoimmune mechanisms. 13,19 Vasoconstriction of the small vessels, chemical irritation by adulterants in inhaled cocaine, and repeated mechanical trauma likely play a role.…”
The authors present a case of a non-traumatic, spontaneous subperiosteal orbital hematoma in a woman with a history of chronic pansinusitis and absence of midline nasal cavity structures due to chronic inhalational cocaine use. The patient underwent left orbitotomy and drainage of the lesion, showing mostly blood with a small amount of purulence that grew methicillin-resistant Staphylococcus aureus when cultured. The patient received 4 weeks of intravenous antibiotics in addition to functional endoscopic sinus surgery. At 1 month after surgery, her vision had returned to baseline, and proptosis was resolved. Fewer than 20 cases of subperiosteal orbital hematomas associated with chronic sinusitis have been reported. To the authors’ knowledge, this is the first reported case of a subperiosteal orbital hematoma associated with cocaine-induced midline destructive lesions. Patient consent to obtain photographs was obtained and archived. All collection and evaluation of patient health information were compliant with the Health Insurance Portability and Accountability Act, and this report adheres to the Declaration of Helsinki.

“…Furthermore, despite the global COVID-19 pandemic, European authorities have intercepted at seaports growing amounts of cocaine in 2020 [5]. All the while, case reports detailing the harmful consequences of cocaine use abound [7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”
Cocaine is one of the most consumed stimulants throughout the world, as official sources report. It is a naturally occurring sympathomimetic tropane alkaloid derived from the leaves of Erythroxylon coca, which has been used by South American locals for millennia. Cocaine can usually be found in two forms, cocaine hydrochloride, a white powder, or ‘crack’ cocaine, the free base. While the first is commonly administered by insufflation (‘snorting’) or intravenously, the second is adapted for inhalation (smoking). Cocaine can exert local anaesthetic action by inhibiting voltage-gated sodium channels, thus halting electrical impulse propagation; cocaine also impacts neurotransmission by hindering monoamine reuptake, particularly dopamine, from the synaptic cleft. The excess of available dopamine for postsynaptic activation mediates the pleasurable effects reported by users and contributes to the addictive potential and toxic effects of the drug. Cocaine is metabolised (mostly hepatically) into two main metabolites, ecgonine methyl ester and benzoylecgonine. Other metabolites include, for example, norcocaine and cocaethylene, both displaying pharmacological action, and the last one constituting a biomarker for co-consumption of cocaine with alcohol. This review provides a brief overview of cocaine’s prevalence and patterns of use, its physical-chemical properties and methods for analysis, pharmacokinetics, pharmacodynamics, and multi-level toxicity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
