    Anesthesia dolorosa caused by penetrating cranial injury
    (Karger, 2006) Tatli, Mehmet; Keklikci, Ugur; Aluclu, Ufuk; Akdeniz, Sedat
    Anesthesia dolorosa (AD) is an uncommon complication of surgical treatments for trigeminal neuralgia. Its incidence is around 0.8%. To our best knowledge, AD caused by a penetrating cranial injury has not been reported previously. We report the case of a 31-year-old male patient with left-sided neuropathic keratitis and AD that began 18 years earlier, following a penetrating cranial injury with a knife to the left postauricular area. The patient was successfully treated by a carbamazepine and gabapentin combination. In conclusion, penetrating cranial injury is uncommon but may cause a serious neurologic disturbance. In the differential diagnosis of AD, a penetrating injury should be kept in mind. In these cases, treatments should be effective and immediate; otherwise, this may result in catastrophic consequences such as neurotrophic keratitis and blindness. Ophthalmologists should be aware of these potential problems. Copyright (c) 2006 S. Karger AG, Basel.

    Elevated plasma N-terminal pro-brain natriuretic peptide levels in acute ischemic stroke
    (Mosby-Elsevier, 2006) Iltumur, Kenan; Karabulut, Aziz; Apak, Ismail; Aluclu, Ufuk; Ariturk, Zuhal; Toprak, Nizamettin
    Background B-type natriuretic peptide (BNP) is a neurohormone secreted mainly in the cardiac ventricles in response to volume expansion and pressure overload. The aim of this study was to assess plasma N-terminal proBNP (NT-proBNP) changes in acute ischemic stroke (AIS). Methods The study group consisted of 57 (37 women aged 64 12 years) patients who had their first AIS and no history or signs of cardiovascular disease. An age-matched control group was also included (n = 57, 36 women aged 61 6 years). NT-proBNP, troponin I (TnI), and creatine kinase-MB were evaluated. A thorough cardiovascular and neurological investigation, including imaging techniques and lesion size determination, was also performed. Results The log NT-proBNP peak levels, TnI, and creatine kinase-MB levels were significantly higher in AIS compared with controls (7.25 +/- 1.77 vs 3.48 +/- 0.76 mu g/mL, P < .0001; 0.76 +/- 0.54 vs 0.5 +/- 0.0 ng/mL, P < .001; 57 +/- 37 vs 13 +/- 4 U/L, P < .001, respectively). The log NT-proBNP correlated positively with TnI (r = 0.29, P = .03) and heart rate (r = 0.41, P = .002), and negatively with left ventricular ejection fraction (r = -0.67, P < .0001). Patients with signs of marked myocardial ischemia and patients with insular cortex involvement had even higher NT-proBNP levels. After adjustment for relevant factors, the relation between the log NT-proBNP and AIS as well as insular cortex involvement was observed to be insignificant (P > .05 for both). Conclusions Our results show that NT-proBNP plasma levels are significantly elevated in AIS and might be of clinical importance as a supplementary tool for the assessment of cardiovascular function in patients with AIS.

    An experimental Staphylococcus aureus meningitis model for investigating induced leptomeningeal and subpial inflammation in rats
    (Maghira & Maas Publications, 2007) Guzel, Aslan; Er, Uygur; Tatli, Mehmet; Aluclu, Ufuk; Ozekinci, Tuncer; Nergiz, Yusuf; Ahishali, Bulent
    OBJECTIVE: To evaluate leptomeningeal and subpial inflammatory responses of experimental Staphylococcus aureus bacteriemia following intraperitoneal and intravenous applications and to compare the inflammatory reactions in different regions of central nervous system. MATERIAL AND METHODS: Forty anesthetized rats were divided into four groups equal in number. The rats in group-I were given 1 ml suspension of Staphylococcus aureus intraperitoneally. Group-II was the control group of group I; it was administrated 1 ml 0.9% NaCl in water intraperitoneally. The rats in group-III were given the same amount of bacteria intravenously. Group IV was the control group of the group-III; it was administrated 1 ml 0.9% NaCl solution intravenously. The rats were sacrificed on the 21st day. Inflammatory changes of different regions of the central nervous system were examined under transmission electron microscopy. Statistical analysis was done by using variance analysis, Bonferroni, Tamhane post hoc, Student's t and univariate tests. RESULTS: Thoracic and occipital regions were the most vulnerable zones. Increasing of collagen tissue was the most detected inflammatory change. CONCLUSION: This experimental model can be used for inducing subpial and leptomeningeal inflammations and it maybe developed for investigations of pathogenesis of leptomeningitis during systemic infections.

    Serum neuron-specific enolase as a predictor of short-term outcome and its correlation with Glasgow Coma Scale in traumatic brain injury
    (Springer, 2008) Guzel, Aslan; Er, Uygur; Tatli, Mehmet; Aluclu, Ufuk; Ozkan, Umit; Duzenli, Yucel; Satici, Omer
    Elevated serum neuron-specific enolase levels are correlated with brain cell damage. Low scores according to Glasgow Coma Scale are also considered as serious poor prognostic factor. The aims of the study were to investigate whether there is a correlation between the two measurements in patients with traumatic brain injury and whether serum neuron-specific enolase levels have potential as a screening test to predict outcome. A total of 169 consecutive patients with traumatic brain injury admitted to our clinic between 2002 and 2005 are included in this study. Those patients, who had any major health problem before trauma, were excluded from the study. However, patients with isolated head injury were included in the study. Serial serum neuron-specific enolase concentrations taken at the first 2, 24, and 48 h after traumatic brain injury were analyzed. A computed tomography was performed on each patient on admission. Their Glasgow Coma Scale scores were recorded serially. The relationship between Glasgow Coma Scale scores and the serum neuron-specific enolase levels were assessed by statistical methods. There was a significant negative correlation between the serum neuron-specific enolase levels and Glasgow Coma Scale scores. The levels of neuron-specific enolase were significantly higher in the patients who died in 30 days after trauma and whose scores were lower than or equal to 8 points in Glasgow Coma Scale. Although there are several serious limitations of the use of neuron-specific enolase as a biomarker in traumatic brain injury (i.e., hypoperfusion, extracranial trauma, bleeding, liver, or kidney damage also increase the level of neuron-specific enolase), its concentrations may be useful as a practical and helpful screening test to identify neurotrauma patients who are at increased risk and may provide supplementary estimation with radiological and clinical findings.
