Background/aim: The pathogenesis of Raynaud's phenomenon (RP) has not yet been fully elucidated. RP is characterized by exaggerated cold-induced vasoconstriction. Urotensin II (UII) is a potent vasoconstrictor. ⋯ Conclusion: The results of the present study suggest that UII is not associated with primary RP. Its level was lower in the secondary RP (SSc) patients. Therefore, it can be concluded that decreased UII level is related to SSc instead of RP.

Background/aim: This study aimed to evaluate the relationship between the Trendelenburg position and cerebral hypoxia in robot-assisted hysterectomy and prostatectomy. Materials and methods: A standardized mini-mental state examination was administered to 50 patients enrolled in the study 1 h before and after surgery. Near infrared spectroscopy (NIRS) values and hemodynamic and respiratory parameters were recorded after induction of anesthesia (baseline) and once every 20 min in the Trendelenburg position and supine positions. ⋯ The relationship between NIRS values and cognitive dysfunction was not significant. Conclusion: We found that cerebral saturation decreases as age increases, and cerebral desaturation may occur owing to the Trendelenburg position. There was no correlation between patients? cognitive function and NIRS values.

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.
