Assessment of patients who presented to the emergency department with mushroom poisoning.

OBJECTIVE: This study aimed to assess the demographic characteristics, emergency department (ED) complaints, laboratory findings, and latent phase periods of patients who presented to the ED due to mushroom poisoning (MP) as well as the efficacy of conventional and hemofiltration therapies. METHOD: The study was conducted on patients who presented to the ED with MP between 2010 and 2012. The patient's demographic characteristics, complaints at the ED, latent phases, laboratory findings, and treatments of MP cases were evaluated. RESULTS: The mean age of patients was 38.03 ± 15.96, where 63.8% of them were female and 36.2% were male. Visits occurred most frequently in the autumn (32.6%). When presenting to the ED, the most frequent complaint was nausea-vomiting. The aspartate aminotransferase (AST), alanine aminotransferase (ALT), international normalised ratio (INR), and blood urea nitrogen values of patients with a latent phase between 0 h and 5 h were significantly lower than the values of patients with a latent phase between 6 h and 24 h. In this study, 62% of the patients (n = 36) had stomach lavage and received activated charcoal. Altogether, 55.2% of the patients had received conventional therapy, 37.9% of them received hemofiltration, and all of them received supportive treatment. The AST, ALT, and INR values of those who had received hemofiltration and conventional therapies were significantly higher than of those who received only supportive treatment (p < 0.01). CONCLUSION: Hemofiltration, in combination with conventional therapy, seems to be an effective treatment for reducing mortality in suspected MP cases involving late acting toxins.

Short aggrecan gene repetitive alleles associated with lumbar degenerative disc disease in Turkish patients.

We investigated a possible association between aggrecan gene polymorphism and lumbar degenerative disc disease in Turkish patients. One hundred 20-30-year-old patients with or without low back pain were selected for the study. Lumbar magnetic resonance imaging was performed on all patients. The patient group had low back pain clinically and degenerative disc disease radiographically. The control group included patients with and without low back pain: all were negative radiographically for degenerative disc disease. Genomic DNA was extracted from all participants. A PCR assay were used to evaluate variable number of tandem repeat polymorphism of aggrecan gene alleles to determine if there was any correlation with degenerative disc disease. Significant associations were found between short repeated alleles of the aggrecan gene and severe disc degeneration. A significant association was also found between short repeated alleles of the aggrecan gene and multilevel disc herniation as well as extrusion and sequestration types of disc herniation. In Turkish population, short repeated alleles of the aggrecan gene are associated with increased disc degeneration and disc herniation.

Association of estrogen receptor alpha and collagen type I alpha 1 gene polymorphisms with bone mineral density in postmenopausal women.

UNLABELLED: In this study, ERα gene PvuII and XbaI polymorphisms and COL1A1 gene Sp1 polymorphisms in postmenopausal women were compared with lumbar vertebra and femoral neck BMD values. In conclusion, it was designated that PvuII polymorphism was effective on average lumbar vertebra BMD value in postmenopausal women of our study group. INTRODUCTION: Bone mineral density (BMD), the major determinant of osteoporotic fracture risk, has a strong genetic component. Several candidate gene polymorphisms have been implicated in the regulation of this process. In this study, the relationship among BMD values of lumbar vertebra and femoral neck and ERα gene PvuII and XbaI polymorphisms and COL1A1 gene Sp1 polymorphism in 126 postmenopausal women (30 normal, 46 osteopenic, and 50 osteoporotic in terms of bone mineral density) was researched. METHODS: The ERα gene PvuII and XbaI genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) whereas the COL1A1 gene Sp1 genotype was determined by real-time PCR. BMDs at the lumbar spine (vertebrae L1-L4) and hip (femur neck) were measured by dual-energy X-ray absorptiometry. RESULTS: According to our study results, the significant difference was found in women with normal, osteopenic, and osteoporotic bone mass in terms of ERα gene PvuII polymorphism "pp" genotype frequency. The "pp" genotype frequency was significantly lower in women with normal bone mass. Average lumbar vertebra BMD value of women with "PP" genotype was significantly higher than that with "pp" genotype. On the other hand, in the evaluations on ERα gene XbaI polymorphism and COL1A1 gene Sp1 polymorphism, it was noted that there was no difference in terms of average BMD values, genotype, and allele frequencies among groups. CONCLUSION: In conclusion, it was designated that ERα gene PvuII polymorphism was effective on average lumbar vertebra BMD value in postmenopausal women of our study group.

C677T polymorphism of the methylenetetrahydrofolate reductase gene does not affect folic acid, vitamin B12, and homocysteine serum levels in Turkish children with neural tube defects.

Association between neural tube defects (NTDs) and C677T polymorphism of the methylenetetrahydrofolate reductase (MTHFR) gene was suspected, because the MTHFR gene codes for a key enzyme in folate metabolism. Its deficiency usually leads to significant reductions in plasma concentrations of folate, vitamin B(12) and methionine, whereas homocysteine levels are increased. We examined folate, vitamin B(12) and homocysteine serum concentrations and polymorphism of the C677T MTHFR gene in Turkish children with neural tube defects. Thirty-three children with NTDs, 26 mothers and 48 healthy individuals were studied. C677T MTHFR polymorphism was determined by melting curve analyses (LightCycler). The levels of folate, vitamin B(12) and homocysteine serum concentrations in NTDs were evaluated and compared, along with information concerning alleles of the MTHFR gene. C677T allele frequencies in NTD children and their mothers were similar to those found in controls. Serum folate and vitamin B(12) concentrations were significantly higher in NTD children than that of controls. Serum homocysteine concentrations were not significantly higher in NTD children and mothers. We concluded that C677T MTHFR gene polymorphism does not affect folic acid, vitamin B(12) and homocysteine metabolism in Turkish children with NTDs. C677T polymorphism of the MTHFR gene cannot be regarded as a major risk factor for NTDs in Turkish children.
