Lead poisoning due to ingestion of lead-contaminated opium: A diagnostic study on patients’ imaging findings

Publication date: September 2019Source: Journal of Trace Elements in Medicine and Biology, Volume 55Author(s): Nasim Zamani, Hossein Hassanian-Moghaddam, Hooman Bahrami-Motlagh, Sara Ahmadi, Scott PhillipsAbstractObjectivesOur study attempts to determine if for patients following ingestion of lead-contaminated opium, radiographs [plain X-ray (KUB)] or unenhanced computed tomography (CT scan) of the abdomen may be predictive of lead poisoning.MethodsOur study is concerned with patients of>21 years with elevated lead concentrations, who had undergone KUB or CT. Patients with other toxicities who had undergone similar imaging profiles but who had low blood lead level (BLL) were enrolled as controls.ResultsWe evaluated a total of 79 cases and 79 controls with median [IQR] BLLs of 126 [97.4, 160] μg/dL and 8.7 [5.5, 15] μg/dL. All cases and eleven controls (13.9%) were addicted to oral opium, and of these cases, anemia (94.9%) and abdominal pain (92.4%) were the two most common clinical manifestations. Two radiologists reviewed the X-ray and non-contrast CTs. Fifty (63.3%) and 53 (67.1%) cases and controls underwent CT scanning with 34 (68%) vs. 6 (11.3%) positive CTs (P

This study was designed to evaluate the clinical and radiographic outcomes of patients with nutcracker syndrome (NCS) who were treated with three-dimensional printing (3DP) extravascular titanium stents (EVTSs). The 3DP EVTS was expected to release the hypertension of the left renal vein (LRV) produced by its compression between the superior mesenteric artery (SMA) and the aorta without causing any complications. METHOD: The pre-operative kidney model of each patient was printed out to enable surgical planning. After that, the EVTS was designed based on the LRV's primitive physiologic structure using computer-aided de...

Magnetic nanoparticles were synthesized and functionalized by l-alanine and l-cysteine amino acids in one step. Besides surface functionalization, amino acid coating also provided favourable particle size. Structural characterization was performed by scanning electron microscopy. We obta...

Almanza RoblesAbstractThe aim of the present work is to study the corrosion of NiAl2O4 spinel by V2O5, Fe2O3 and vanadium slag. Samples of NiAl2O4 spinel with the oxides mentioned above were heated at 10 °C/min from room temperature up to 1500 °C. Holding time was 12 h and cooling rate was 10 °C/min. The effects of these oxides on the corrosion of NiAl2O4 spinel were simulated at the beginning with HSC®5.1 so...

This study proposes a novel water in oil (W/O) nanoemulsion dielectric for use in high-speed compound sinking machining. The compound machining is the combination of arc machining and electric discharge machining (EDM). The performance of the compound machining using the proposed W/O nanoemulsion is investigated systemically by comparing with that using the traditional water based dielectric. The influences of electrode polarity, peak current, and pulse duration on the material removal rate (MRR) and relative electrode wear rate (REWR) are studied. Moreover, the characteristics of machined surface are investigated using sc...

RosembergAbstractThe ability to detect noxious stimuli is essential to survival. However, pathological pain is maladaptive and severely debilitating. Endogenous and exogenous opioids modulate pain responses via opioid receptors, reducing pain sensibility. Due to the high genetic and physiological similarities to rodents and humans, the zebrafish is a valuable tool to assess pain responses and the underlying mechanisms involved in nociception. Although morphi...
