Purpose: There is a high possibility of trauma patients being referred to an unsuitable medical institution for their rehabilitation treatment since the decision is made by them. This study sought to develop a standardized scale to evaluate the need for specialized rehabilitation in patients with multiple traumas and evaluate the effectiveness of the developed scale. Methods: This study employed a systematic review of existing literature to inform the development of a specialized rehabilitation evaluation scale. An expert panel consisting of trauma surgeons, orthopedic surgeons, and rehabilitation medicine physicians collaborated to create a discharge-planning checklist by assessing the need for specialized rehabilitation. The checklist was validated using retrospective data from trauma patients treated at Seoul National University Hospital. Results: We identified 12 studies, providing factors influencing the discharge location and rehabilitation needs of trauma patients. The checklist was developed through expert consensus and comprised 3 criteria: discharge feasibility to specialized rehabilitation facilities, diagnostic eligibility for specialized rehabilitation, and functional assessment. Validation of the checklist demonstrated that the percentage agreement, likelihood ratio of a positive test, and Cohen’s kappa value were 82.1%, 5.21, and 0.375, respectively when comparing whether the checklist was met and the actual discharge location, indicating its effectiveness. Conclusion This study established standardized criteria for assessing the need for specialized rehabilitation in trauma patients, offering a practical tool for clinical use. Implementation of this assessment scale has the potential to improve the trajectory of trauma survivors by facilitating access to appropriate rehabilitation services.

Partially thrombosed intracranial aneurysm was difficult to treat because of higher recurrence rate compared to non-thrombosed saccular aneurysm. The author reports a case of partially thrombosed intracranial aneurysm causing transient ischemic symptom. A 40-year-old man presented with transient right hemiparesis. Brain magnetic resonance imaging (MRI) depicted low-signal intensity target-like mass lesion on left sylvian fissure, and magnetic resonance angiography (MRA) showed aneurysm on left middle cerebral artery bifurcation (MCBF), suggested thrombosed aneurysm. On operative finding, aneurysm wall had thick and atherosclerotic change, and it was fusiform aneurysm not saccular type. We initially planned direct clip for the aneurysm, but it was failed due to collapse of parent artery after clipping on aneurysm neck. To prevent ischemia, extracranial-intracranial bypass was performed and then thrombectomy with clip reconstruction. To remodeling the fusiform aneurysm, stent-assisted coiling was performed for remnant portion of aneurysm. With staged hybrid technique, giant thrombosed fusiform aneurysm was completely obliterated and the patient did not suffer any neurologic symptoms no longer.

PURPOSE: Recently, randomized controlled trials have reported that conservative therapy can be a treatment option in patients with noncomplicated appendicitis. However, preoperative diagnosis of noncomplicated appendicitis is difficult. In this study, we determined predictive factors to distinguish patients with noncomplicated appendicitis from those with complicated appendicitis. METHODS: A total of 351 patients who underwent surgical treatment for acute appendicitis from January 2011 to December 2012 were included in this study. We classified patients into noncomplicated or complicated appendicitis groups based on the findings of abdominal computed tomography and pathology. We performed a retrospective analysis to find factors that could be used to discriminate between noncomplicated and complicated appendicitis. RESULTS: The mean age of the patients in the complicated appendicitis group (54.5 years) was higher than that of the patients in the noncomplicated appendicitis group (40.2 years) (P < 0.001), but the male-to-female ratios were similar. In the univariate analysis, the appendicocecal junction's diameter, appendiceal maximal diameter, appendiceal wall enhancement, periappendiceal fat infiltration, ascites, abscesses, neutrophil proportion, C-reactive protein (CRP), aspartate aminotransferase, and total bilirubin were statistically significant factors. However, in the multivariate analysis, the appendiceal maximal diameter (P = 0.018; odds ratio [OR], 1.129), periappendiceal fat infiltration (P = 0.025; OR, 5.778), ascites (P = 0.038; OR, 2.902), and CRP (P < 0.001; OR, 1.368) were statistically significant. CONCLUSION: Several factors can be used to distinguish between noncomplicated and complicated appendicitis. Using these factors, we could more accurately distinguish patients with noncomplicated appendicitis from those with complicated appendicitis.

BACKGROUND: Ferulic acid (FA) is a naturally occurring nutritional compound. Although it has been shown to have antihypertensive effects, its effects on vascular function have not been intensively established. The aim of this study was to assess the vasoreactivity of FA in chronic two-kidney, one-clip (2K1C) renal hypertensive rats. METHODS: Hypertension was induced in 2K1C rats by clipping the left renal artery and age-matched rats that received a sham treatment served as a control. Thoracic aortas were mounted in tissue baths to measure isometric tension. The effects of FA on vasodilatory responses were evaluated based on contractile responses induced by phenylephrine in the aortic rings obtained from both 2K1C and sham rats. Basal nitric oxide (NO) bioavailability in the aorta was determined by the contractile response induced by NO synthase inhibitor NG-nitro-L-arginine methyl ester (L-NAME). RESULTS: FA induced concentration-dependent relaxation responses which were greater in 2K1C hypertensive rats than in sham-clipped control rats. This relaxation induced by FA was partially blocked by the removal of endothelium or by pretreating with L-NAME. L-NAME-induced contractile responses were augmented by FA in 2K1C rats, while no significant differences were noted in sham rats. FA improved acetylcholine-induced endothelium-dependent vasodilation in 2K1C rats, but not in sham rats. The simultaneous addition of hydroxyhydroquinone significantly inhibited the increase in acetylcholine-induced vasodilation by FA. CONCLUSION: These results suggest that FA restores endothelial function by altering the bioavailability of NO in 2K1C hypertensive rats. The results explain, in part, the mechanism underlying the vascular effects of FA in chronic renal hypertension.

PURPOSE: The aim of this study was to evaluate the quality of the trauma care system of our hospital, in which emergency physicians care for major trauma patients in the emergency intensive care unit (ICU) in consultation with intervention radiologists and surgeons. METHODS: This was a retrospective observational study conducted in an emergency ICU of a tertiary referral hospital. We enrolled consecutive patients who had been admitted to our emergency ICU with major trauma from March 2007 to September 2010. We collected data with respect to demographic findings, mechanisms of injury, the trauma and injury severity score (TRISS), emergency surgery, angiographic intervention, and 6-month mortality. Then, we compared the observed and predicted survivals of the patients. The Hosmer-Lemeshow test and calibration plots by using 10 groups, one for each decile, of predicted mortality were used to evaluate the fitness of TRISS. P-values of greater than 0.05 represent a fair calibration. RESULTS: Among 116 patients, 12 (10.34%) were dead within 6 months after admission to the ICU, and 29 (25.00%) and 38 (32.80%) patients received emergency surgery and angiographic intervention, respectively. The mean injury severity score and revised trauma score were 36.97+/-17.73 and 7.84+/-6.75, respectively. The observed survival and the predicted survival of the TRISS were 89.66% (95% confidence interval [CI]: 84.03~95.28%) and 69.85% (95% CI: 63.80~75.91%), respectively. The calibration plots showed that the observed survival of our patients was consistently higher than the predicted survival of the TRISS (p<0.001). CONCLUSION: The observed survival for the trauma care system of our hospital, in which emergency physicians care for major trauma patients in the emergency ICU in consultation with intervention radiologists and surgeons, was higher than the predicted survival of the TRISS.

PURPOSE: To compare the clinical outcomes of the ulnar shortening osteotomy alone and the ulnar shortening osteotomy with arthroscopic debridement in the idiopathic ulnar impaction syndrome with positive ulnar variance. MATERIALS AND METHODS: Twenty seven cases, who underwent the ulnar shortening osteotomy with or without arthroscopic debridement for treatment of the idiopathic ulnar impaction syndrome with positive ulnar variance, were included. The mean age was 40.3 years (range, 21 to 63 years) and the mean follow-up period was 20.6 months (range, 12 to 60 months). The ulnar shortening osteotomy alone and the ulnar shortening osteotomy with arthroscopic debridement were performed in 14 and 13 cases respectively. Pre- and postoperative functional results of the wrist were evaluated by the modified Mayo wrist score. RESULTS: The ulnar variance was corrected from 4.61 mm (range, 1.8~10 mm) to -0.06 mm (range, -3.3~3.1 mm) in the ulnar shortening osteotomy alone group and from 3.01 mm (range, 1.2~7.6 mm) to -0.74 mm (range, -1.8~0 mm) in the ulnar shortening osteotomy with arthroscopic debridement group. The final results of the ulnar shortening osteotomy alone were excellent in 4 cases, good in 5 cases, and fair in 5 cases. Those of the ulnar shortening osteotomy with arthroscopic debridement group were excellent in 6 cases, good in 2 cases, fair in 1 case, and poor in 2 cases. The modified Mayo wrist score at the last follow-up were 83.57(range, 75~100) in the ulnar shortening osteotomy alone group and 83.35(range, 40~100) in the ulnar shortening osteotomy with arthroscopic debirdement group. No statistically significant difference was demonstrated between two groups (p=0.43). CONCLUSION: The ulnar shortening osteotomy is valuable treatment for the idiopathic ulnar impaction syndrome with positive ulnar variance. The combined arthroscopic debridment does not appear to have positive influence to the final results.

PURPOSE: Cyclosporine A (CsA) is a versatile immunosuppresive agent used to prevent graft rejection syndrome and treat autoimmune disease. One of the major side effects associated with CsA is the abnormal gingival hyperplasia. The purpose of this study was to investigate the relationship between the mRNA expression of the MMP-1, TIMP-1, and TGF-beta1 and the concentration of CsA in cultured human gingival keratinocytes. MATERIALS AND METHODS: Gingival keratocytes were obtained from gingival tissues of 4 healthy donors. The cultured gingival keratocytes were incubated with increasing concentrations of CsA (0-2000 ng/ml) for 24 hours and the expression of MMP-1, TIMP-1, and TGF-beta1 were determined by reverse transcription-polymerase chain reaction (RT-PCR). RESULTS: The expressions of MMP-1 and TGF-beta1 were not significantly different according to the concentrations of CsA. The expression of TIMP-1 was significantly increased at the CsA concentration of 500 ng/ml. CONCLUSION: We concluded that the gingival hyperplasia induced by CsA was more related with TIMP-1 than MMP-1 or TGF-beta1 on gingival collagen metabolism in patients treated with CsA.

BACKGROUND AND OBJECTIVES: Inverted papilloma is a benign tumor of nasal cavity and paranasal sinuses with a propensity for local invasiveness, recurrence, and malignant transformation. Proteomics is a powerful tool for protein analysis, providing valuable information on biochemical processes involved in diseases, monitoring of cellular processes, and characterizing the protein expression levels. We tried to find the proteins that are associated with pathophysiology of the inverted papilloma and mechanisms of the disease by proteomic approach. MATERIALS AND METHOD: Normal nasal mucosa and inverted papilloma tissue was obtained during augmentation rhinoplasty and endoscopic surgery, respectively. Total protein was isolated and separated into numerous spots by two-dimensional electrophoresis. Twenty four protein spots that were only detected in inverted papilloma were selected and subsequently analyzed with matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS). RESULTS: About 700 protein spots were detected. Selected spots were analyzed, and various proteins were identified. These include T-cell receptor beta chains, Ca2+ binding proteins, caltractin, calneuron, ras-related proteins, a rab-2b oncogene family, chloride intracellular channel proteins, tumor protein D53, and tumor necrosis factor precursors. CONCLUSION: We identified the proteins expressed in the inverted papilloma with proteomic approach. These proteins may help us in understanding the mechanisms of pathogenesis of inverted papilloma, and may be used as possible tumor markers.
