Background/aim: Head injuries are commonly seen in the pediatric population. Noncontrast enhanced cranial CT is the method of choice to detect possible traumatic brain injury (TBI). Concerns about ionizing radiation exposure make the evaluation more challenging. ⋯ With "cranial CT/observation of patient; both are appropriate" results, pathology presence was predicted 11,457-fold compared to "not appropriate for cranial CT" results. Conclusion: PECARN rules can predict pathology presence successfully in pediatric TBI. Using PECARN can decrease resource waste and exposure to ionizing radiation.

Background/aim: Various flap procedures have been described and used for the lower eyelids; however, the nasolabial flap is rarely employed. We herein aimed to present the clinical results of using the superiorly based nasolabial island flap for repair of surgical defects extending to the lateral lower eyelid. Materials and methods: Nine patients with a mean age of 62 +- 6 years underwent surgery for reconstruction of the lower eyelid. ⋯ Conclusion: Despite the low number of patients, the present series demonstrated that lower eyelid defects involving zone IV or zone V can be repaired safely and reliably with the superiorly based nasolabial island flap, along with its use shown in the literature for zone II or zone III defects. The technique for raising the flap is fairly simple, with predictable surgical results. In addition, the superiorly based nasolabial island flap provides a reliable means of obtaining good wound healing with acceptable aesthetics, as well as functional results of both the donor site and reconstructed area.

Background/aim: The purpose of this study was to analyze the clinicopathological characteristics of patients with papillary thyroid carcinoma (PTC) and papillary thyroid microcarcinoma (PTMC) and predictive factors for central lymph node metastasis (CLNM). Materials and methods: Patients diagnosed as having PTC and PTMC were evaluated. Clinical and laboratory parameters were recorded. ⋯ However, multivariate logistic regression analysis showed that sex, age, tumor size, multifocality, bilaterality, extrathyroidal extension, clinical suspicion, and chronic lymphocytic thyroiditis were not significantly correlated with an increased risk for CLNM. Conclusion: Lymph node metastasis is known to be a significant predictor of locoregional recurrence in patients with PTC and PTMC. Further prospective studies are needed to identify the extent of surgery such as central lymph node dissection in patients with PTC or PTMC.

Background/aim: Isolated cell cultures are widely used to study neuronal properties due to their advantages. Although embryonic animals are preferred for culturing, their morphological or electrophysiological properties may not reflect adult neurons, which may be important in neurodegenerative diseases. This paper aims to develop a method for preparing isolated cell cultures of medial vestibular nucleus (MVN) from adult mice and describe its morphological and electrophysiological properties. ⋯ Current-clamp recording of the cultured neurons revealed tonic and phasic-type neurons with similar input resistance, resting membrane potential, action potential amplitude, and duration. Conclusion: Vestibular neurons from adult mice can be cultured, and regenerate axons in a medium containing appropriate growth factors. Culturing adult vestibular neurons provides a new method to study age-related pathologies of the vestibular system.

The reno-protective effects of atorvastatin in crush syndrome and rhabdomyolysis:is there a dilemma?
Background/aim: We aim to determine the effects of low-dose atorvastatin treatment together with crush fluid resuscitation on renal functions and muscle enzyme levels in a rat model of crush syndrome. Materials and methods: The study involved female Wistar Albino rats weighing 250-300 g that were housed with free access to food and water. The crush model was obtained by compression. ⋯ However, there was no statistically significant difference among treatment groups regarding any of the parameters. Conclusion: This is the first study determining the role of atorvastatin in the treatment of renal ischemia/reperfusion injury in a crush syndrome and rhabdomyolysis model setting. Larger studies with different atorvastatin doses are required to define the role of this drug in the treatment of renal ischemia/reperfusion injury during crush syndrome.
