Objective: To evaluate the visual evoked potentials (VEP) in Graves’ disease patients in order to reveal the possible presen- tation of subclinical optic neuropathy. Methods: Forty-seven Graves’ disease patients without symptoms of optic neuropathy were enrolled. Flash visual evoked potentials (F-VEP) and Pattern visual evoked potentials (P-VEP) were evaluated. Comparison of VEP with normal values was done, between the groups with and without the presentation of eye sign(s) and also among the groups that had differ- ences in thyroid hormone function. Results: The mean F-VEP amplitude and latency were 17.56±6.20 microvolts (μV) and 114.02±14.92 milliseconds (ms), respectively. The mean P-VEP amplitude and latency were 10.82±4.88 μV and 99.67±5.87 ms, respectively. These values were within normal values. Only the latency of P-VEP was increased signi cantly (P<0.001) when compared between the groups with (101.81±5.70 ms) and without eye signs (97.43±5.21ms) and it also increased signi cantly (P=0.033) when compared with normal values. The hyperthyroid group also had a signi cant increase in the latency of P-VEP when compared to other groups (P=0.002). Conclusion: Increase in the latency of P-VEP should be sought for and reminded the clinician to conduct close follow-up of this as an early sign of optic neuropathy, especially in the patients with eye manifestation.

Objective: To study the predictive power of systemic in ammatory response syndrome (SIRS) scores, platelet count, and blood glucose level for multiple organ dysfunction syndrome (MODS) in patients with major trauma. Methods: The sample was 87 patients with major trauma, hospitalized within 24 hours after injury. SIRS score, platelet count and maximum blood glucose level were measured within the rst 24 hours after injury, while MODS was measured by the Denver post-injury multiple organ failure (MOF) score at the 3rd day after injury. Multiple regression analysis, using the enter method, was employed to analyze the data with a signi cance level of .05. Results: The majority of the samples were male (85.1%) with an average age of 40.39 years. Most of them sustained multiple organ injuries and received surgical treatment within the rst 24 hours. It was found that 25.3% of these patients developed organ dysfunction on the 3rd day after injury while 9.2% experienced MODS. SIRS score, platelet count and blood glucose level could predict MODS in patients with major trauma, with 41.7% of the variance explained (R2= .417, p < .001). Conclusion: Patients with major trauma should receive close monitoring on their SIRS score, platelet count and blood glucose level within 24 hours after injury. Moreover, Denver post-injury MOF score should be routinely used for detection of organ dysfunction so that preventative measures can be appropriately implemented.

Intranasal tooth is a rare phenomenon. The clinical manifestations of an intranasal tooth are quite variable. Unila- teral nasal obstruction is a common complaint. In this case, a 14-year-old girl presented with left nasal obstruction. Anterior rhinoscopy and endoscopic examination showed the tooth-like lesion in the left nasal cavity. Computed Tomography (CT) scanning is helpful in the diagnosis and treatment planning. After a complete evaluation, the patient underwent transnasal endoscopic removal of the lesion. In the present study, the clinical and radiological ndings of a nasal tooth is reported.
