Evaluation of simple blood counts as inflammation markers for brain tumor patients.

AIMS: Hemogram parameters in routine blood panels have been proposed as inflammation markers. These parameters, especially the red cell distribution width (RDW) and mean platelet volume (MPV), were evaluated as surrogate inflammatory markers in brain tumor patients. We aimed to observe RDW and MPV values of tumor patients and compare to those in healthy population. METHODS: We recorded white blood cell count, neutrophil count, lymphocyte count, hemoglobin, hematocrit, RDW, platelet count, and MPV of the study group at the time of diagnosis and compared to those of the control subjects. RESULTS: The RDW was significantly elevated in study group compared to that of the control subjects (p=0.001). The MPV was significantly lower in study group than that of the control group (p=0.01). CONCLUSION: Decreased MPV and increased RDW were both associated with brain tumor. However, prospective studies with larger sample sizes are needed to support the results and expose MPV and RDW variations between metastatic and primary brain tumors.

Investigation of the relationship between kinesiophobia, physical activity level and quality of life in patients with chronic low back pain1.

OBJECTIVE: The aim of our study is to examine the relationship between kinesiophobia (fear of movement), physical activity level and quality of life. METHODS: In this study, we assessed 112 patients consulting for low back pain (LBP) of ≥ 3 month's duration. We used Visual Analog Scale (VAS) for pain intensity, the International Physical Activity Questionnaire (IPAQ) for physical activity level, Tampa Kinesiophobia Scale for perception of kinesiophobia, Oswestry Disability Index for disability status of low back. RESULTS: The results of this study, there was no statistically significant correlation between International Physical Activity Questionnaire, duration of pain, intensity of pain at rest and Tampa Kinesiophobia Scale (p> 0.05). It was found a statistically significant correlation between pain intensity at activity (p= 0.009), disability level (p= 0.000) and Tampa Kinesiophobia Scale. Tampa Kinesiophobia Scale were highly negative correlated with sub-scale of SF-36 Quality of Life Index (general health, physical function, social status, bodily pain, role limitations due to physical health) (p= 0.000). CONCLUSION: The kinesiophobia adversely affect the quality of life limiting the physical activity status of patients with chronic low back pain.

Spontaneous recovery of post-traumatic cerebrospinal fluid rhinorrhea following meningitis: A case report.

The aim of the present report was to present the patient with an anterior cranial base fracture who developed post-traumatic cerebrospinal fluid rhinorrhea, which recovered after onset of meningitis complication. A 26-year-old male patient who had a traffic accident one week ago was sent to our clinic because of his rhinorrhea persisting for 4 days. On cranial computed tomography, fracture of the left frontal skull base and sinus walls, a fracture line on temporal bone, parenchymal bleeding in the vicinity of the frontal sinus, subarachnoidal bleeding and left temporal extradural hematoma were detected. Then he underwent sinus wall repair and extradural hematoma was drained through bifrontal craniotomy. However, rhinorrhea persisted which resulted a deterioration in consciousness and he entered into a deep somnolent state. When his symptoms of meningitis became apparent, rhinorrhea of the patient disappeared. The patient transferred in intensive care unit and re-connected to a lumbar drainage system. On cerebral magnetic resonance imaging, regression of contrast-enhanced lesions localized in the left anterotemporal and frontal and in the regions lateral to the right trigon and medial to the right thalamus and in the right posteroparietal regions was observed. Despite repair of the anterior cranial fracture and lumbar drainage, rhinorrhea may persist. Herein, development of meningitis caused disappearing of rhinorrhea symptoms without any need for surgical intervention.

Spontaneous remission of a big subligamentous extruded disc herniation: case report and review of the literature.

Spontaneous Regression of a Big Subligamentous Extruded Disc Herniation: Case Report And Review of The Literature The most efficient method for the treatment of lumbar disc herniation is still controversial. The most important aspect is the application of the suitable conservative or surgical treatment to the right patient at the right time. In lumbar disc herniation patients, one must not precipitate except for cases that require surgical indications as in cauda equina syndrome, evolutive motor deficit and persistence of pain in spite of the narcotics. However, the spontaneous regression mechanism has not been completely determined yet. The proposed hypotheses are; dehydration, retraction of the disc to the hernia in the annulus fibrosis, enzymatic catabolism and phagocytosis. In this study, the case of a patient with huge lumbar disc hernia regressing by itself has been presented and the potential mechanisms of disc regression have been discussed.

Temozolomide may induce cell cycle arrest by interacting with URG4/URGCP in SH-SY5Y neuroblastoma cells.

Temozolomide (TMZ) is an alkylating drug used usually in glioma treatment by inducing the apoptosis in glioma cell. The aim of the study is to investigate the anticancer mechanism of TMZ in SH-SY5Y human neuroblastoma cell line. Cytotoxic effects of TMZ were determined by using XTT assay. IC50 doses in the SH-SY5Y were detected as 5 mM. Expression profiles of novel genes URG4/URGCP, CCND1, CCND2, CDK4, and BCL2 were determined by real-time PCR. The apoptotic effects of TMZ were evaluated with TUNEL method. Furthermore, effects of TMZ on colony formation and invasion were investigated in this study. It was observed that TMZ in SH-SY5Y cell line caused a significant decrease in the gene expressions of URG4/URGCP, CCND1, CCND2, CDK4, and BCL2. According to TUNEL assay results, TMZ markedly induced apoptosis in SH-SY5Y cell line. It was found that TMZ in SH-SY5Y cell line suppressed invasion and colony formation using matrigel invasion chamber and colony formation assay, respectively. To conclude, it is thought that TMZ demonstrates anticarcinogenesis activity by affecting cell cycle arrest, apoptosis, invasion, and colony formation on SH-SY5Y cells. TMZ may be an effective agent for treatment of neuroblastoma as a single or in combination with other drugs.

Choroidal thickness and retinal vascular caliber correlations with internal carotid artery Doppler variables.

PURPOSE: Decreased retinal arteriolar caliber and increased retinal venular caliber have been associated with increased cardiovascular mortality. This study aimed to evaluate correlations of choroidal thickness and retinal vascular caliber measurements with internal carotid artery (ICA) Doppler ultrasound variables. METHODS: In this cross-sectional and observational study, 43 eyes and ICAs of 43 healthy volunteers were examined. Spectral domain optical coherence tomography was used to measure subfoveal choroidal thickness (SFCT) and retinal vascular caliber. The ICA Doppler ultrasonographic parameters were diameter, flow volume, peak-systolic velocity, end-diastolic velocity, resistance index (RI), and pulsatility index (PI). RESULTS: Negative correlations emerged between ICA RI and SFCT (p = 0.017, r = -0.36) as well as between ICA PI and retinal arteriolar caliber (p = 0.015, r = -0.37). A negative linear correlation appeared between ICA diameter and SFCT (p = 0.005, r = -0.42), although ICA diameter and flow volume showed no association with retinal vessel caliber (p > 0.05). CONCLUSIONS: Choroidal thickness is negatively correlated with ICA diameter and ICA RI, while retinal arteriolar caliber is inversely related with ICA PI in normal volunteers.

Unusual presentation of multiple nerve entrapment: a case report.

Cubital tunnel syndrome is the most common form of ulnar nerve entrapment and the second most common entrapment neuropathy of the upper extremity after carpal tunnel syndrome. However, bilateral compressive ulnar neuropathy is a rare condition. Electro diagnostic studies are a valid and reliable means of confirming the diagnosis.
