ABSTRACT

Background: Sonographic measurement of optic nerve sheath diameter (ONSD) can reflect intracranial pressure (ICP) indirectly and determine the neurology intensive care unit (NICU) requirement and mortality in acute ischemic stroke (AIS). Aim: To demonstrate the effectiveness of ONSD to determine mortality, morbidity, and NICU requirement on patients with the AIS. Methods: The sonographic ONSD measurements were performed on each patient with AIS, over 18 years old. All patients were categorized according to the Oxfordshire Community Stroke Project (OCSP) classification system. MRI images were examined for increased ICP, and the patients were categorized into two groups as increased ICP (i-ICP) and normal ICP. The ONSD results were evaluated in terms of classifications, outcomes, and prognosis of the patients. Results: One hundred and five patients were included and 31 (35.2%) were in the i-ICP group. The median ONSDs were 5.26 mm in the i-ICP group and 4.62 mm in the normal ICP group (P < 0.001). The median ONSDs were 5.13 mm in the NICU group and 4.69 mm in the neurology ward (NW) group (P = 0.001). The total anterior circulation infarction (TACI) subgroup had higher ONSDs than the others (TACI: 5.27 mm; PACI: 4.73 mm; POCI: 4.77 mm; and LACI: 4.64 mm, P < 0.001). The NICU requirements were higher in the TACI subgroup. The median ONSD was 5.42 mm in the deceased group (survived: 4.77 mm, P < 0.001). Conclusion: ONSD may be favorable for predicting the increased ICP and the NICU requirement in OCSP subgroups. Moreover, ONSD can be used to foresee the mortality of AIS.

ABSTRACT

OBJECTIVE: In this study, we aimed to investigate the relation between the mRNA expression levels of VHL, TIMP-3 and RASSF1A genes, and the histopathological and clinical characteristics of patients with renal tumors. PATIENTS AND METHODS: Radical nephrectomy specimens of cases presented without neoadjuvant treatment were confirmed to be cancerous, non-cancerous, benign, and healthy after removal from separate localizations. A total of 69 patients with kidney tumors (138 tissue samples) were included in the study group. RNA isolation, reverse transcriptase PCR (RT-PCR), and quantitative real time PCR (qPCR) were performed, and the GAPDH gene was used to normalize mRNA levels. RESULTS: In the RCC cancerous tissue, TIMP-3 levels increased 1.3 times and RASSF1A levels increased 1.4 times compared to the corresponding levels in non-cancerous tissues, and there was no statistically significant difference in these values. On the other hand, VHL gene expression levels in cancerous tissue were 2.8 times higher than in matched adjacent non-cancerous tissues (p < 0.05). In the case of oncocytomas, TIMP-3 levels were found to be 3.2 times higher, RASSF1A levels 3.8 times higher, and VHL levels 2.2 times lower than the corresponding levels in healthy tissues (p < 0.05). CONCLUSIONS: The roles of VHL, TIMP-3, and RASSF1A mRNA expression in contributing to the development of renal tumors could not be clearly established. Further studies are therefore required to elucidate the mechanisms underlying renal tumors.

ABSTRACT

BACKGROUND: There is an increasing trend for administration of invasive radiological interventions, laparoscopic surgery, and transplantation procedures in recent years, and determining the vascular variations prior to these procedures is crucially important. Coeliacomesenteric trunk (CMT) is among these variations. This study aimed to retrospectively evaluate this rare anomaly by computed tomography (CT). MATERIALS AND METHODS: A total of 1000 CT angiography images were analysed retrospectively, and the patients with mesenteric and coeliac arteries arising from the abdominal aorta with a single root were identified. The level that CMT arose, and its branching patterns were determined individually for all patients. RESULTS: Ten patients (6 males and 4 females) with a mean age of 50.2 years (17-87 years) had CMT in CT images. CONCLUSIONS: The knowledge of variations in the CMT prior to vascular or laparoscopic interventions will contribute to early intervention in case of a complication, or to avoid from a potential damage.
