Phenytoin intoxication with no symptoms correlated with serum drug level: a case study
In high-dose intake of phenytoin, which is used frequently to treatepilepsy, nystagmus, diplopia, nausea-vomiting, lethargy, confusion, seizure, and coma can be observed. In recent studies on phenytoin intoxication, in which seizure and coma were observed in drug levels greater than 50 ug/mL. The serum phenytoin level of apatient, who consumed approximately 100 pcs of 100 mg phenytoin tablets in an effort to commit suicide, and who had no pathological finding in her neurologic examination, was 124 ug/mL. High drug level and the absence of toxic effect (or the absence of toxic effect correlated with the drug level) indicates that cytochrome P450 is functioning, but there can be a mutation in the MDR1 gene. In our case study, we report on phenytoin intoxication in a patient having a high level of phenytoin but no symptoms correlated with serum drug level, as supported by the findings in the literature.Pan African Medical Journal 2015; 2
Increased fat graft survival with mesenchymal stem cell recruiting effect of PRP: in vitro and in vivo study of application techniques
Aim: Adding platelet-rich plasm (PRP) or mesenchymal stem cells are the most accepted methods to increase fat graft’s permanence. However, there is no consensus on timing and whether the effect of stem cells or PRP is observed more in the recipient area or in the donor area.
It is aimed to present the application method and localization of PRP to be combined with fat graft to increase the survival.
Material and Methods: in vitro part: Fat grafts were kept in a medium containing PRP. Cell output from the fat graft to the Petri dishes was examined every day. The time to recruit the maximum number of stem cells to the medium was determined (day 10). in vivo part: Eight group of rats were received PRP in different concentrations either to recipient or donor areas of fat grafts. After ten days, fat grafts were transferred to the recipient area. Ninety days after the transfer, histopathological examination and immunohistochemical staining were performed.
Results: The group which had received the full-dose PRP to the recipient area showed the highest cellular integrity and vascularity (p< 0.05). Vascularity was superior in the half-dose PRP group compared to the control group (p< 0.05); cellular integrity did not increase. Donor site groups did not show increase in cellular integrity.
Conclusion: Although PRP starts to increase fat graft permanence by increasing vascularity, it acts by preserving the cellular integrity of the fat cells as the concentrations increase. The PRP injection to the recipient area 10 days before fat grafting may provide higher survival rates
Efficacy of Hyaluronic Acid in The Selection of Human Spermatozoa with Intact DNA by The Swim-up Method
Objective: In 2014, enrolled 20 patients who applied to the Unit of Assisted Reproduction
Techniques, Konya Necmettin Erbakan University. Based on the presence of hyaluronic
acid (HA) in the oocyte-cumulus cell complex, sperm attached to HA in vivo were modeled
in vitro. Available healthy sperm obtained in the swim-up procedure using HA were
investigated.
Materials and Methods: This observational cohort study, a routine analysis was conducted
on the ejaculation samples obtained from 20 patients. We divided each sample
into two groups and the swim-up method was applied. Human serum albumin (HSA, 0.5%)
was added to samples from the first group. HA (10%) was added to samples from the second
group. We determined the floating linear and non-linear sperm concentrations of both
groups annexin V was used to determine the rate of apoptosis of these sperm.
Results: Following swim-up, linear and non-linear sperm concentrations were higher in
the group that contained HA compared to the group with HSA. However, there was a significantly
higher apoptosis rate in the HSA group compared to the HA group.
Conclusion: The addition of HA to the medium in the swim-up procedure positively affected
sperm parameters. Thus, healthier sperm cells were obtained without DNA damage
and with high motility
Influence of beta-1,3/1,6 glucan applications on some non-specific cellular immune response and haematologic parameters of healthy Nile tilapia (Oreochromis niloticus L., 1758)
WOS: 000274886800011In this study, the effects of beta-glucan administration at different dosages on non-specific immune response and haematological parameters in healthy Nile tilapia (Oreochromis niloticus L.) were investigated. Fish were fed with diets containing 0.5% and 0.1% glucan (experiment) and without glucan (control) for 2 weeks. After feeding for 2 weeks with 2 different dosages, erythrocyte (RBC), leukocyte (WBC), hematocrit (Hct), haemoglobin (Hb) amount, leukocyte cell types (percentage of lymphocyte, monocyte, neutrophil, eosinophil), the values of phagocytic activities, erythrocyte cell indexes (MCV and MCH) and blood cell sizes were determined. WBC and phagocytic activity amounts, percentages of lymphocyte and monocyte of fish fed with the diets containing 0.1% glucan were higher than 0.5% glucan and control groups (P 0.05).Academic Research Projects Unit of Cukurova UniversityCukurova University [FBE-2002-YL-211]This research was supported by the Academic Research Projects Unit of Cukurova University ( Project Number: FBE-2002-YL-211
Improvement In Rabbit Corneal Cell Suspension Viability After Freezing With Gingko Biloba Extrakt
We investigated whether the addition of Gingko Biloba extract (EGb 761) to rabbit corneal epithelial medium before cell freezing improved cell viability after freezing then thawing. After removal of corneas, they were treated with enzymes and the corneal epithelium was prepared as a single cell suspension in freezing media with or without EGb 761. After freezing for two weeks then thawing, a higher cell viability was found in the cornea cell suspensions which had been frozen pretreated with EGb 761 in the media. The improvement with corneal cell viability with EGb 761 pretreatment is postulated to be based on the antioxidant capacity of the plant extract
Balloon Dilatation of Iatrogenic Ureteral Strictures after Upper Urinary Tract Reconstruction
Purpose: Open pyeloplasty is the gold standard treatment of uretero-pelvic junction (UPJ) stenosis. Although failure after open pyeloplasty or uretero-neosistosmy is not common, percutaneous or endoscopic interventions must be necessary in some cases. We present treatment of 6 pediatric patients by balloon dilatation after failed surgery.
Material and Methods: Between 2008 and 2013 6 children were treated. Five patients had undergone open pyeloplasty for UP stenosis and, one has uretero-vesical anastomosis stricture after ureteroneosistostomy. Percutaneous antegrade balloon dilatation and double J stent placement were performed in three of six patients. In the other three patients retrograde endoscopic balloon dilatation and double J stent placement were performed.
Results: Primary technical success was %50 and %100 for antegrade and retrograde approach respectively. Antegrade approach has failed in 3 patients (%50) and, retrograde approach and treatment were successful in all of these patients. Secondary and tertiary balloon dilatations were done through antegrade approach in 3 patients. Mean duration of double J stent was 114 days. As of today, five patients are followed smoothly. One patient who has UP stenosis underwent secondary open surgery.
Conclusion: Balloon dilatation can be used safely in both antegrade and retrograde approaches because of lower profile of balloon catheters, so it could be considered as a first line treatment option after failed surgical treatment of upper urinary tract stenosis in children
Novel EYA1 variants causing Branchio-oto-renal syndrome
Branchio-oto-renal (BOR) syndrome is an autosomal dominant genetic disorder characterized by second branchial arch anomalies, hearing impairment, and renal malformations. Pathogenic mutations have been discovered in several genes such as EYA1, SIX5, and SIX1. However, nearly half of those affected reveal no pathogenic variant by traditional genetic testing.
Whole Exome sequencing and/or Sanger sequencing performed in 10 unrelated families from Turkey, Iran, Ecuador, and USA with BOR syndrome in this study.
We identified causative DNA variants in six families including novel c.525delT, c.979T > C, and c.1768delG and a previously reported c.1779A > T variants in EYA1. Two large heterozygous deletions involving EYA1 were detected in additional two families. Whole exome sequencing did not reveal a causative variant in the remaining four families.
A variety of DNA changes including large deletions underlie BOR syndrome in different populations, which can be detected with comprehensive genetic testing
