In Europe it is estimated that around 13. million of adults (15-64. years) have used cocaine at least once in their lifetime. The most frequently used route of administration for the drug is intranasal inhalation, or "snorting", and thus the adverse effects of cocaine on the nasal tract are very common. Habitual nasal insufflations of cocaine may cause mucosal lesions, and if cocaine use becomes chronic and compulsive, progressive damage of the mucosa and perichondrium leads to ischemic necrosis of septal cartilage and perforation of the nasal septum. Occasionally, cocaine-induced lesions cause extensive destruction of the osteocartilaginous structures of nose, sinuses and palate that can mimic other diseases such as tumors, infections, and immunological diseases. Thorough diagnostic workup, including endoscopic, radiologic, histopathologic and serologic testing is imperative to arrive at the proper diagnosis and to initiate appropriate local and systemic treatment. Positive antineutrophil cytoplasmic antibody (ANCA) test results may be found in an unexpectedly large proportion of patients with CIMDL. In several instances their lesions are clinically indistinguishable from granulomatosis with polyangiitis (Wegener's) limited to the upper respiratory tract. CIMDL seem to be the result of a necrotizing inflammatory tissue response triggered by cocaine abuse in a subset of patients predisposed to produce ANCA, particularly those reacting with HNE. The presence of these HNE-ANCA seems to promote or define the disease phenotype. CIMDL do not respond well to immunosuppressive therapy. Only the consistent removal of persistent stimuli of autoantibody production (cocaine, bacterial superinfections) can halt the disease process, prevent the progression of the lesions and promise success of surgical repair procedures. © 2012 Elsevier B.V.

Mental health and addiction services have traditionally evolved separately in many European countries, with policy reflecting this. Differences in severity profiles between users of the community addiction services with comorbidities of mental illness and substance misuse and those with substance misuse only were studied using a matched case-control study design, with regard to the main substance (opiates or cocaine) patients were dependent on. Patterns of substance abuse and diagnostic features were evaluated according to the Addiction Severity Index (ASI) and DSM-IV. Mentally ill substance abusers are significantly more likely to have used amphetamines, inhalants and having been polydrug users. They are particularly impaired in medical and family/social relationships ASI composite scores, but less in drug use. Severity profiles and needs of dually diagnosed patients require assessment and treatment skills that should be provided through adequate links with mental health system. Copyright © 2006 S.

We report the case of a 35-year-old man who presented at our institution with intramural aortic hematoma shortly after inhaling cocaine and smoking crack cocaine. To our knowledge, such a case has not previously been reported in the English medical literature. Problems of diagnosis and the mechanisms of intramural hematoma and aortic dissection are discussed.
