introduction : very severe head trauma cases, defined as glasgow coma scale (gcs) scores of less than 6, have a higher mortality rate and poorer outcome. the purpose of this study was to recognize factors associated with survival and 6-month favorable outcome of very severe head trauma patients presenting to emergency department.  methods: in this historical cohort study, the authors retrospect...

background: venoarterial extracorporeal membrane oxygenation (ecmo) provides systemic arterial support without directly unloading the left heart, which causes an elevated left ventricular (lv) pressure. the aim of the present study was to investigate the adjunctive application of the impella device for lv unloading in patients during ecmo. methods: this retrospective cohort study included patie...

introduction: allogeneic hematopoietic stem cell transplantation is a potentially curative treatment modality for hematological malignancies. we evaluated the outcome of patients suffering from hematological malignancies, including acute leukemias, chronic myeloid leukemia and myelodysplastic syndrome after allogeneic transplantation. methods: all patients having hematological malignancies with...

background: c linical trials of revascularization have routinely under-enrolled elderly subjects. thus, symptom relief and improved survival might not apply to elderly patients, in whom the risk of mortality and disability from revascularization procedures seems to be high and co-morbidity is more prevalent. the present case control study was performed to draw a comparison in terms of the proce...

purpose: to report the clinical findings and compare the outcomes of different surgical techniques evolved over time in a large series of patients with delayed-onset mustard gas keratitis (mgk). methods: this interventional retrospective case series includes patients with complications of delayed mgk. medical and surgical interventions to address dry eye, limbal ischemia and limbal stem cell de...

purpose: mesh technique is the standard for inguinal hernia repair because of less recurrence,   but it is inferior or equal to sutured technique in case of other post-operative complications   such as chronic pain. this clinical trial set out to compare these two techniques.   materials and methods: a total number of 322 cases of unilateral inguinal hernia in participants   older than 18 years...

purpose: in this study, we have focused on antibacterial effect of newly synthesized thiazole, imidazole and tetrahydropyrimidine derivatives in iran on listeria monocytogenes. materials and methods: for evaluation of antibacterial effect, the disk diffusion method was applied to measure the growth inhibition zone diameter and broth micro dilution was performed to determine the minimum inhibito...

nocardiosis has been reported increasingly in recent two decades, probably due to improvement in isolation of the organism and increased burden of immune compromised patients. nocardia occasionally has been reported in healthy people. a case series of definitive nocardiosis (2002 to 2010), clinical characteristics, underlying diseases, immune status and in-patient outcome were studied in a tert...

background: the aim of this study was to determine the treatment outcome of humeral shaft fractures with a locked rigid intramedullary nail in patients indicated for surgical treatment. methods: in this descriptive-cross sectional study, all patients were followed up for one, six, and 18 months post operatively. the short form questionnaire (sf-36) and constant shoulder score were applied. resu...

background: mean platelet volume (mpv) correlates with platelet activity. the relation between mpv and long-term outcome in patients undergoing percutaneous coronary intervention (pci) has been investigated in several studies. the aim of the present study was to investigate the utility of mpv in prognosticating the long-term outcome after elective pci. methods: the study cohort included 2627 pa...
