PURPOSE: This study attempts to know functional results and gait analysis usefulness in patients with bone tumor around knee joint tumors who underwent prosthesis knee joint reconstruction. MATERIALS AND METHODS: Retrospective study was conducted with 7 patients out of 30 patients who underwent prosthesis knee joint reconstruction after wide marginal excision for bone tumor around knee in orthopedics of this hospital from 2001 to 2010. Functional assesment and gait analysis were perforemed. RESULTS: For the SF-36 score, while 'role physical' and 'role emotional' items showed 100% (100 points) high scores individually, general health, physical function, vitality, and social function showed low scores. The mean score of MSTS was 88.1% (23.8 points [17-27]), indicating a relatively high score. For the gait analysis, mean gait velocity was 97.2 m/s, mean cadence was 105.6 step/min, mean stride length was 111.3 m, mean step length was 61.5 cm, swing phase was 39.8%cycle, stance phase was 60.1%cycle, mean single limb support was 37.1%cycle, mean double limb support was 13.0%cycle, and mean push off was 60.7%cycle. CONCLUSION: It is expected that prosthesis reconstruction after wide marginal excision for bone tumor around knee has relatively good functional results. Gait analysis was considered one of method which showed gait phase and assessed functional ability objectively by quantitative assessment post operative patient condition. It might help treatment and post operative rehabilitation planning with the fuctional assessment.

PURPOSE: To evaluate the anatomical relation between anterior ethmoidal sinus and the lacrimal sac fossa, and thus help prevent complications during dacryocystorhinostomy. MATERIALS AND METHODS: Fifty three people without previous history of trauma, surgery, or paranasal sinus disease were randomly selected, and the 106 lacrimal sac fossas of these subjects were evaluated by high resolution CT. A series of three 2-mm thick axial sections at least 2 mm from the inferior orbital wall were obtained. The bony landmarks of the lacrimal sac fossa were established and the location of the most anterior ethmoid sinus was classified as one of three types. In type 1, no sinuses were anterior to the posterior lacrimal crest. while in type 2, sinuses extended anterior to this crest but remained behind the suture at the anterior edge of the lacrimal bone. In type 3, sinuses extended into the frontal process of the maxilla, anterior to the lacrimal bone suture. In addition, the category of both orbits of the same patient was compared. RESULTS: Among the 106 orbits examined, only seven (6.6%) were classified as type 1, with no ethmoid air cells positioned under the lacrimal sac fossa. Seventy six (71.7%) qualified as type 2, while the remaining 23 (21.7%) were type 3, demonstrating anterior ethmoid air cells within the nasal process of the maxilla. The position of the air cells was symmetric in 41 of the 53 subjects (77.4%) and asymmetric in 12 (22.6%). CONCLUSION: In cases involving surgery of the lacrimal sac fossa, such as dacryocystorhinostomy, a knowledge of the consistent anatomic relationship between the anterior ethmoidal sinus and the lacrimal sac fossa is invaluable.

Trigeminal neuralgia (TN) is a common condition that produces pain in the orofacial area. However, the exact cause of TN is still unknown. Various etiologies such as tumor, multiple sclerosis and other compressive lesions have been implicated as possible causes. A 35-year-old woman was admitted due to right facial pain which was diagnosed as TN. A brain MRI revealed sphenoidal sinusitis with epidural empyema. We report a case of complicated sinusitis with epidural empyema presenting as TN.

BACKGROUND: A systematic literature review of interspinous dynamic stabilization, including DIAM, Wallis, Coflex, and X-STOP, was conducted to assess its safety and efficacy. METHODS: The search was done in Korean and English, by using eight domestic databases which included KoreaMed and international databases, such as Ovid Medline, Embase, and the Cochrane Library. A total of 306 articles were identified, but the animal studies, preclinical studies, and studies that reported the same results were excluded. As a result, a total of 286 articles were excluded and the remaining 20 were included in the final assessment. Two assessors independently extracted data from these articles using predetermined selection criteria. Qualities of the articles included were assessed using Scottish Intercollegiate Guidelines Network (SIGN). RESULTS: The complication rate of interspinous dynamic stabilization has been reported to be 0% to 32.3% in 3- to 41-month follow-up studies. The complication rate of combined interspinous dynamic stabilization and decompression treatment (32.3%) was greater than that of decompression alone (6.5%), but no complication that significantly affected treatment results was found. Interspinous dynamic stabilization produced slightly better clinical outcomes than conservative treatments for spinal stenosis. Good outcomes were also obtained in single-group studies. No significant difference in treatment outcomes was found, and the studies compared interspinous dynamic stabilization with decompression or fusion alone. CONCLUSIONS: No particular problem was found regarding the safety of the technique. Its clinical outcomes were similar to those of conventional techniques, and no additional clinical advantage could be attributed to interspinous dynamic stabilization. However, few studies have been conducted on the long-term efficacy of interspinous dynamic stabilization. Thus, the authors suggest further clinical studies be conducted to validate the theoretical advantages and clinical efficacy of this technique.

OBJECTIVES: Mild Alzheimer's disease(AD) is uncertain to be related to visuospatial working memory subsystem dysfunction. We used the self ordered pointing test(SOPT) to find the characteristics of visuospatial working memory in mild AD. METHODS: We compared the visuospatial working memory abilities of 20 patients with mild AD and 20 normal elderly controls(NC) using SOPT, of which stimuli consisted of two stimuli types(A: abstract, C: concrete) and two stimuli numbers(8 and 12). Therefore, working memory was tested using C8, C12, A8, and A12 stimuli conditions in SOPT. Mixed-model ANOVA was conducted with the AD and NC groups as between-subjects factor, with stimuli types and stimuli numbers as the within-subjects factors and with SOPT error rates as the dependent variable. RESULTS: The AD group showed higher error rates in SOPT than the NC group. The NC group showed low error rates in concrete stimuli than in abstract stimuli and in small stimuli numbers than in large stimuli numbers. And the AD group showed no differences between stimuli types or stimuli numbers. CONCLUSION: AD patients showed a poor performance in visuospatial working memory using concrete stimuli. The result suggests that there is a non-transformation from visual input to phonological working memory in AD. Patients with AD showed a poor performance although in small stimuli number condition of SOPT. It suggests that in AD, visuospatial working memory is not working well although in low central executive loads.

Hypercalcemia is one of the most common paraneoplastic syndromes and believed to occur through two general mechanisms, one humoral and the other local. The former mechanism has been termed humoral hypercalcemia of malignancy (HHM) and has been associated with the secretion of various cytokines, including parathyroid hormone-related protein (PTHrP). PTHrP beats sttuctural and functional similarities to PTH and seems to play a key role in the pathogenesis of HHM. We experienced the case of HHM associated with hepatoma, a rare cause of HHM, in 48 year-old male. We found no evidence of bone metastasis. In this case, contrary to our general acknowledgment, serum 1,25 (OH)D concentration was elevated. We report this case with a brief review of related literatures.

PURPOSE: The aim of the study was to investigate the change in usage and clinical outcomes of using a humidified high flow nasal cannula (HHFNC) in preterm infants. METHODS: A retrospective review of patients with gestational age <32 weeks born at our neonatal intensive care unit from January 2008 to March 2011 was performed. First, data were compared between Era 1 (January 2008 to February 2009) and Era 2 (March 2009 to March 2011) to describe the increased usage of HHFNC. Second, the patients (gestational age 25-30 weeks) were divided into two groups to compare clinical outcomes. nasal continuous positive airway pressure (NCPAP) and HHFNC groups who received either NCPAP or HHFNC as a respiratory support within 14 days of birth. RESULTS: Compared to Era 1, HHFNC usage increased from 10 to 55% in Era 2, whereas NCPAP usage decreased from 40 to 5%. No difference in pulmonary or adverse outcomes including the incidence of reintubation and bronchopulmonary dysplasia (BPD), days on oxygen and a ventilator, and other outcomes was observed between the HHFNC and NCPAP groups. Days to reach full feed (32.2+/-16.7 vs. 24.7+/-10.2, P=0.05) and regain birth weight (20.9+/-16.9 vs. 17.2+/-4.3, P=0.04) decreased in the HHFNC group. CONCLUSION: HHFNC was feasible and did not differ in respiratory and other outcomes, but days to reach full feed and regain birth weight decreased in the HHFNC, when compared with the NCPAP. An additional prospective multicenter designed study is needed to better define safety and efficacy of HHFNC.
