OBJECTIVE: Intranasal substance abuse with cocaine or opioids can result in complications involving the midline nasal and oral structures. When the defect involves the velopharyngeal musculature, this leads to velopharyngeal dysfunction (VPD). This article aims to illustrate this clinical entity through a series of four patients and a review of the literature. METHODS: A series of four cases of VPD due to intranasal narcotic use and their management are discussed...

A 50-year-old man presented with acute onset dyspnea following cocaine use. He had severe aortic stenosis (AS), mild mitral regurgitation (MR) due to mitral valve prolapse, and no coronary artery disease on recent coronary angiography. He was in acute heart failure with signs of impending cardiogenic shock. Urgent bedside echocardiography revealed hyperdynamic left ventricular systolic function with acute severe MR from a ruptured chordae tendineae. The acute cocaine-induced spike of his already elevated left ventricular systolic pressure from severe AS likely precipitated chordal rupture of his vulnerable mitral valve...

Cocaine, a natural alkaloid derived from the coca plant, is one of the most commonly used illicit drugs. Cocaine abuse causes systemic adverse effects like stroke, myocardic infarction, arterial dissection, vascular thrombosis and rhabdomyolysis. Cocaine use is, also, associated with renal complications such as acute kidney injury, vasculitis, acute interstitial nephritis, chronic kidney disease, malignant hypertension with thrombotic microangiopathy. Acute kidney injury may or may be not associated to rhabdomyolysis...

Aortic dissection is a rare and fatal complication of cocaine-induced hypertension. The injury mechanism is through shear stress that penetrates the intimal vessel layer, allowing blood flow to separate intimal and medial layers. Due to its scarcity and the paucity of related literature, our knowledge of this condition is limited. We present a rare case of a cocaine-induced aortic dissection, which extended continuously from the aortic root to the common iliacs, along with a literature review of similar cases...

Isolated spontaneous renal artery dissection (RAD) without known trauma is rare, and its etiology has not been determined. However, notable risk factors including hypertension, strenuous exercise, connective tissue disorders, atherosclerosis, extracorporeal shock wave lithotripsy, and cocaine abuse have been reported. To the best of our knowledge, isolated RAD caused by lumbar vertebra osteophytes in patients with degenerative lumbar scoliosis has not been reported in the literature. In this article, we present a case of RAD caused by lumbar vertebra osteophyte in a patient with degenerative scoliosis and discuss the management of the disease...

Aims: Despite alcohol being the most often used addictive substance among addicted patients, use of other substances such as cocaine has increased over recent years, and the combination of both drugs aggravates health impairment and complicates clinical assessment. The aim of this study is to identify and characterize heterogeneous subgroups of cocaine- and alcohol-addicted patients with common characteristics based on substance use disorders, psychiatric comorbidity and impulsivity. Methods: A total of 214 subjects with cocaine and/or alcohol use disorders were recruited from outpatient treatment programs and clinically assessed...

RATIONALE: Paper spray ionization (PSI) is an attractive ambient ionization source for mass spectrometry (MS) since it allows the combination of surface sampling and ionization. The minimal sample preparation inherent in this approach greatly reduces the time needed for analysis. However, the ions generated from interfering compounds in the sample and the paper substrate may interfere with the analyte ions. Therefore, the integration of PSI with high-field asymmetric ion mobility spectrometry (FAIMS) is of significant interest since it should reduce the background ions entering the mass analyzer without complicating the analysis or increasing analysis time...

Advances in medical diagnosis reveal that coronary artery aneurysms (CAAs) may develop in several clinical scenarios and manifest variable symptoms, imaging appearances, and outcomes. Aneurysms are pathologically classified into three groups: atherosclerotic, inflammatory, and noninflammatory. The last category is associated with congenital, inherited, and connective tissue disorders. Overlap exists among the groups, because secondary atherosclerotic change may be present in an aneurysm of any cause. Atherosclerosis is the most common cause of CAAs in adults, and inflammation is considered the underlying mechanism...

Background Marijuana is a widely used recreational substance. Few cases have been reported of acute myocardial infarction following marijuana use. To our knowledge, this is the first ever study analyzing the lifetime odds of acute myocardial infarction (AMI) with marijuana use and the outcomes in AMI patients with versus without marijuana use. Methods We queried the 2010-2014 National Inpatient Sample (NIS) database for 11-70-year-old AMI patients. Pearson Chi-square test for categorical variables and Student T-test for continuous variables were used to compare the baseline demographic and hospital characteristics between two groups (without vs...

Robert W Harkness V, Philip E Johnson, Anthony K Mittermaier
Differential scanning calorimetry (DSC) is a powerful technique for quantifying thermodynamic parameters governing biomolecular folding and binding interactions. This information is critical in the design of new pharmaceutical compounds. However, many pharmaceutically relevant ligands are chemically unstable at the high temperatures used in DSC analyses. Thus, measuring binding interactions is challenging because the concentrations of ligands and thermally-converted products are constantly changing within the calorimeter cell...

HIV-1 and addictive drugs, such as cocaine (COC), may act in combination to produce serious neurological complications. In the present experiments, striatal brain slices from HIV-1 transgenic (Tg) and F344 control female rats were studied. First, we examined dopamine (DA) reuptake in control, HIV-1, COC-treated (5µM) and HIV-1+COC-treated, striatal slices using fast scan cyclic voltammetry. COC-treated striatal slices from F344 control animals significantly increased DA reuptake time (T80), relative to untreated control slices...

Local anesthetics are commonly used medicines in clinical settings. They are used for pain management during minor interventional treatments, and for postoperative care after major surgeries. Cocaine is the well-known origin of local anesthetics, and the drug and related derivatives have long history of clinical usage for more than several centuries. Although illegal use of cocaine and its abuse are social problem in some countries, other local anesthetics are safely and effectively used in clinics and hospitals all over the world...

REVIEW
Helen E Ritchie, Diana J Oakes, Debra Kennedy, Jaimie W Polson
Hypoxia is a normal and essential part of embryonic development. However, this state may leave the embryo vulnerable to damage when oxygen supply is disturbed. Embryofetal response to hypoxia is dependent on duration and depth of hypoxia, as well as developmental stage. Early postimplantation rat embryos were resilient to hypoxia, with many surviving up to 1.5 hr of uterine clamping, while most mid-gestation embryos were dead after 1 hour of clamping. Survivors were small and many had a range of defects, principally terminal transverse limb reduction defects...
