A case of cocaine-induced panhypopituitarism with human neutrophil elastase-specific anti-neutrophil cytoplasmic antibodies

Are We Witnessing a New Wave of Substance Use Disorders?: A Spotlight on Stimulant Use Disorders

Stimulant use disorders are emerging as a serious global threat to health. Although research, clinical, and policy efforts have largely concentrated on opioid use disorders over the past decade, exponential rises in prevalence and overdose deaths attributable to stimulant use disorders warrant renewed attention. To date, no approved medications are available to treat stimulant use disorders; however, behavioral interventions have been effective and should be proactively promoted. Similarly, complementary and integrative therapies and harm reduction services have emerging evidence for effectiveness in treating these conditions. Research, practice, and policy interventions should address stigma for medications for stimulant use disorders when available, vaccine hesitancy if vaccines are approved and safe, environmental surveillance to reduce population exposure to toxic effects of methamphetamines, and educational interventions for health providers to increase competency to reduce the long-term effects on various body systems.

Cocaine-Induced Pituitary and Subdural Brain Abscesses and the Treatment Challenges

Cocaine is a well-known recreational drug with stimulant effects associated with relevant social, economic, and clinical implications. The most common route of abuse is via snorting. It has high addictive potential. Furthermore, one of the most well-known symptoms of a chronic user is chronic rhinitis. In the medical journals, there are numerous reports of complications, including lesions affecting the nasal septum, nasal sinuses, and even brain abscesses. We came across a 41-year-old male patient with severe manifestations of chronic cocaine use involving nasal, paranasal, and visual symptoms and signs. However, the most devastating was the complication of pituitary abscess, as a sequela to chronic cocaine sniffing. This case highlights the clinical, diagnostic, and management challenges with a multi-disciplinary approach. Last but not least, was the role of patient counselling and education. This ensured compliance towards management with a favourable outcome, which was rewarding for both the patient and the medical team involved in the care of the patient. It would hopefully create more awareness and assist in abstinence. We also hope it would incite more effort towards data collection and analysis, as well as allow us to explore the actual incidence of its use and devastating complications, which to date, for reasons of disguise and denial, remain somewhat ambiguous.

Substance Abuse and Male Hypogonadism

Progressive deterioration of male reproductive function is occurring in Western countries. Environmental factors and unhealthy lifestyles have been implicated in the decline of testosterone levels and sperm production observed in the last fifty years. Among unhealthy lifestyles, substance and drug abuse is a recognized cause of possible alterations of steroidogenesis and spermatogenesis. Alcohol, opioids and anabolic-androgenic steroids are capable to reduce testosterone production in male interfering with testicular and/or hypothalamic-pituitary function. Other substances such as nicotine, cannabis, and amphetamines alter spermatogenesis inducing oxidative stress and subsequent apoptosis in testicular tissue. Substance and drug abuse is a potentially reversible cause of hypogonadism, defined as the failure of the testis to produce physiological concentrations of testosterone and/or a normal number of spermatozoa. The identification of the abuse is important because the withdrawal of substance intake can reverse the clinical syndrome. This review summarizes the most important clinical and experimental evidence on the effect of substance abuse on testosterone and sperm production.

Vascular disease in cocaine addiction

Cocaine, a powerful vasoconstrictor, induces immune responses including cytokine elevations. Chronic cocaine use is associated with functional brain impairments potentially mediated by vascular pathology. Although the Crack-Cocaine epidemic has declined, its vascular consequences are increasingly becoming evident among individuals with cocaine use disorder of that period, now aging. Paradoxically, during the period when prevention efforts could make a difference, this population receives psychosocial treatment at best. We review major postmortem and in vitro studies documenting cocaine-induced vascular toxicity. PubMed and Academic Search Complete were used with relevant terms. Findings consist of the major mechanisms of cocaine-induced vasoconstriction, endothelial dysfunction, and accelerated atherosclerosis, emphasizing acute, chronic, and secondary effects of cocaine. The etiology underlying cocaine's acute and chronic vascular effects is multifactorial, spanning hypertension, impaired homeostasis and platelet function, thrombosis, thromboembolism, and alterations in blood flow. Early detection of vascular disease in cocaine addiction by multimodality imaging is discussed. Treatment may be similar to indications in patients with traditional risk-factors, with few exceptions such as enhanced supportive care and use of benzodiazepines and phentolamine for sedation, and avoiding β-blockers. Given the vascular toxicity cocaine induces, further compounded by smoking and alcohol comorbidity, and interacting with aging of the crack generation, there is a public health imperative to identify pre-symptomatic markers of vascular impairments in cocaine addiction and employ preventive treatment to reduce silent disease progression.

The manifestation of cocaine-induced midline destructive lesion in bone tissue and its identification in human skeletal remains

Cocaine-induced midline destructive lesion (CIMDL) is a condition that may arise in response to chronic insufflation ("snorting") of cocaine. It is clinically diagnosed when the nasal septum, lateral nasal walls, and/or hard palate show signs of destruction in association with cocaine use. Although its true incidence is unknown, CIMDL is not an uncommon clinical finding amongst intranasal cocaine abusers and is likely to be encountered by forensic anthropologists and medical examiners working worldwide. Given the preponderance of drug abusers amongst the subjects of forensic casework, the ability to diagnose CIMDL in dry bone may provide crucial insight into an investigation and even help confirm an individual identification. This paper aims to make practicing forensic anthropologists aware of CIMDL. Through the analysis of existing clinical literature, patient CT scans, and histology sections, it works toward the establishment of formal diagnostic criteria for identifying CIMDL in human skeletal remains. Lytic destruction regularly involves the vomer and frequently extends to the perpendicular plate of the ethmoid, the palatal process of the maxillae or the palatine bones, and the inferior nasal conchae. The middle nasal conchae, medial walls of the maxillary sinuses, ethmoid sinuses, and cribriform plate are often damaged. Destruction may also implicate the superior nasal conchae, the orbit, and the sphenoid. Bones affected by CIMDL may contain necrotic lesions or may be absent entirely. Lesions show minimal, if any, signs of repair. The author proposes that this lack of new bone formation may be mediated by potentially elevated leptin levels in cocaine abusers and CIMDL patients and may be the key to differentiating CIMDL from other lytic processes of the midface.

Acute hypopituitarism in a pregnant patient after cardiac gunshot injury

Sheehan's syndrome is a well described entity that refers to hypopituitarism with pituitary infarction secondary to postpartum shock or hemorrhage. Antepartum pituitary infarction is a very rare condition that has been reported only in patients with longstanding type 1 diabetes mellitus or uncontrolled gestational diabetes. A case of severe, acute hypopituitarism in the setting of hemorrhagic shock from a gunshot wound is presented. Our case report highlights the importance of including hypopituitarism in the differential diagnosis of a critically ill parturient.

Diagnostic approach to ANCA-associated vasculitides

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) include Wegener's granulomatosis, microscopic polyangiitis, and Churg-Strauss syndrome. Given their rarity, protean clinical manifestations, imperfect diagnostic tests, and wide differential diagnosis, they pose a diagnostic challenge even to experienced clinicians. This article describes diagnostic approaches for patients suspected of having one of the ANCA-associated vasculitides. The clinical findings at presentation, the role of laboratory and imaging tests, and the importance of tissue diagnosis are presented. In each section, issues relevant to the differential diagnosis of AAV are discussed.
