Trace elements are essential components of biological structures, but alternatively, they can be toxic at concentrations beyond those necessary for their biological functions. Changes in the concentration of essential trace elements and heavy metals may affect acute hemorrhagic stroke. The aim of this study was to measure serum levels of essential trace elements [iron (Fe), zinc (Zn), manganese (Mn), copper (Cu), and magnesium (Mg)] and heavy metals [cobalt (Co), cadmium (Cd), and lead (Pb)] in patients with acute hemorrhagic stroke. Twenty-six patients with acute hemorrhagic stroke and 29 healthy controls were enrolled. Atomic absorption spectrophotometry (UNICAM-929) was used to measure serum Fe, Cu, Pb, Cd, Zn, Co, Mn and Mg concentrations. Serum Cd, Pb and Fe levels were significantly higher in patients with acute hemorrhagic stroke than controls (p < 0.001), while serum Cu, Zn, Mg and Mn levels were significantly lower (all p < 0.001). However, there was no significant difference between the groups with respect to serum Co levels (p > 0.05). We first demonstrate increased Cd, Pb, and Fe levels; and decreased Cu, Zn, Mg, and Mn levels in patients with acute hemorrhagic stroke. These findings may have diagnostic and prognostic value for acute hemorrhagic stroke. Further studies are required to elucidate the roles of trace elements and heavy metals in patients with acute hemorrhagic stroke.
Purpose: It is well known that trace elements and heavy metals play a significant role in human health and disease. These elements play an important role in different metabolic pathways of cells and tissues. Trace element deficiency or excess is implicated in the development or progression of some cancers. We present a study which investigates serum/ plasma levels of trace-heavy elements in metastatic colon cancer patients and healthy subjects. Methods: Blood samples were collected from 29 healthy subjects and 40 patients with metastatic colon cancer in Oncology Department of Medical School of Yuzuncu Yil University. In both groups, the serum levels of copper (Cu), magnesium (Mg), lead (Pb), chromium (Cr), zinc (Zn) selenium (Se), manganese (Mn), and cadmium (Cd) were determined. Results: Higher levels of Cu, Mg, Pb, Cr, Zn, Mn and Cd were seen in patients with metastatic colon cancer compared to healthy subjects and these findings were statistically significant (p < 0.05). Se levels were noted to be lower in patients with colon cancer in comparison to healthy subjects and this finding was also statistically significant (p < 0.05). Conclusions: According to our findings there was significant diffence in trace elements and heavy metals levels between healthy subjects and metastatic colon cancer patients. Therefore heavy metal and trace elements may have prognostic significance in complex disorders including colon cancer. However, further comprehensive studies are needed in order to advance our understanding of the relationship between heavy metal and trace elements and their role in cancers.
IntroductionBoth hepatitis B virus (HBV) and hepatitis D virus (HDV) infection play an increasingly important role in liver diseases. The main objective of this study was to investigate the socio-epidemiological, laboratory and radiological aspects of both HBV and HDV infection near the Iranian border of Turkey.Material and methodsThe study included 3352 patients with HBV and HDV infection. Socioepidemiological, laboratory and radiological aspects of the study subjects were retrospectively examined. Comorbid metabolic diseases were not assessed due to the retrospective design of the study.ResultsMost of the study subjects were HBe antigen negative. No significant difference in terms of HBV-DNA levels or HBe antigen seropositivity was detected between the city centre and rural areas (p > 0.005). The mean HBV-DNA level in the anti-HDV-positive group was significantly lower than in the anti-HDV-negative group (p < 0.001). The rate of HDV-RNA positivity in women was higher than in their male counterparts (p = 0.017). Anti-HDV-IgG was detected in 18.4% of tested subjects who came from an urban area. In contrast, 12.5% of subjects of the rural group had a positive result for anti-HDV-IgG. Among 134 ultrasonographically evaluated delta hepatitis patients, 37.3% had liver cirrhosis. On the other hand, in 1244 patients with hepatitis B monoinfection, there were 90 patients with liver cirrhosis. Radiologically, the rate of hepatic steatosis in delta hepatitis patients was lower than in those with HBV monoinfection.ConclusionsHepatitis D virus infection was particularly prevalent among the urban population as well as in female subjects. More broadly, the current observations are the first to suggest an inverse correlation between delta hepatitis and ultrasonography-proven hepatic steatosis.
The results were shown that administration of dexmedetomidine reduced the renal IR injury histomorphologically. Administration of dexmedetomidine in the reperfusion period was considered as more effective due to increase in urinary output and decrease in BUN levels.
A 33-year-old male patient experienced temporary sensory loss and weakness in the right lower extremity one month prior to admission. The patient was admitted to a private clinic with a three-day history of acute onset of sensory loss and weakness in both lower extremities and was treated and followed up with a prediagnosis of transverse myelitis and the Guillain-Barre syndrome (GBS). The patient was subsequently transferred to our clinic and the neurologic examination revealed paraplegia in both lower extremities, positive bilateral Babinski signs, and hypesthesia below the T10 dermatome with saddle anesthesia. The patient had urinary incontinence and thoracic magnetic resonance imaging (MRI) showed an image of a mass compressing the medulla.
