Benign solitary osteochondroma are the most common benign bone tumor, and often arise in the long bone of the extremities about 80% of lesions, particulary about the knee and the upper extremity. In rare cases, the spine is involved. We describe a case in which a solitary sacral osteochondroma compressed the lumbosacral plexus, producing sensory disturbance. The tumor was removed through the anterior midline approach. The excised mass was round, lobulated, measuring 7. 5cm×6cm, pedunculated type and the cartilage cap is complete and is 4mm in thickness.

Small cell cancer commonly occurs in the lungs, but it is rarely found in other organs. Small cell cancer that occurs in the pancreas is rare and its progress very rapid, and most patoents' tumor has already spread by metastasis when it is discovered. Although this cancer has a poor prognosis, we report here on treating case with combined curative resection and chemotherapy and showed a good prognosis.

Alpha-fetoprotein (AFP) is a well-known tumor marker for hepatocellular carcinoma, hepatoblastoma, and yolk sac tumors. There are several studies on AFP-producing tumors that arose from the gastrointestinal tract, pancreas, lung, kidney, and urachal tract. AFP-producing carcinoma of the gallbladder is extremely rare. We report a case of AFP-producing carcinoma of the gallbladder without liver involvement in a 58-year-old man with a gallstone, on which clinical, morphologic, and immunohistochemical studies were performed.

OBJECTIVE: To identify useful imaging findings for the diagnosis of idiopathic adhesive capsulitis of the hip (ACH) on computed tomography arthrography (CTA). MATERIALS AND METHODS: Twenty-eight consecutive patients (29 hips; 7 males; mean age, 45.7 years; age range, 17–67 years) with ACH from October 2009 to March 2017 and 29 age- and sex-matched control patients from 2014 to 2016 were enrolled. All CTA images were evaluated by 2 radiologists independently for joint distensibility (anterior-posterior [AP] and superior-inferior [SI] joint cavity filling ratios), the presence of contrast filling around the ligamentum teres, and extracapsular contrast leakage. Fisher's exact test, Mann-Whitney U test, analysis of variance, and receiver operating characteristic curves were used for statistical analysis. P value less than 0.05 was considered to indicate statistical significance. RESULTS: The anterior joint cavity was significantly more obliterated in the ACH group (mean size, 3.7–4.0 mm) than in the control group (mean size, 4.8–5.0 mm; p < 0.05). The AP filling ratio was also significantly lower in the ACH group (0.6 vs. 1.1; p < 0.05) and decreased more as the ACH stage increased (mean anterior joint cavity size: 1.15 mm in stage 3 vs. 4.68 mm in stage 1; p < 0.05). Extracapsular contrast leakage was more common in the ACH group (27–28 vs. 20–21; p = 0.041 and 0.025, respectively). CONCLUSION: On CTA, the anterior joint cavity may have earlier and more marked obliteration than joint cavities on other sides, and may be accompanied by extracapsular contrast leakage in ACH. These CTA findings may be helpful in the diagnosis of ACH.

Background:
Spine-hip discordance (SHD) increases fracture risk. However, its prevalence and clinical implications have not been investigated in patients with hip fractures. This study determined the prevalence and association of SHD with mortality and investigated the cause of SHD in patients with hip fractures.
Methods:
This study included patients admitted for fragility hip fractures between 2011 and 2020. All patients underwent dual energy X-ray absorptiometry and anteroposterior and lateral views of the lumbosacral spine during admission. Data on demographics, diagnosis, American Society of Anesthesiologists score, and mortality were collected. A T-score difference of more than 1.5 between L1-4 and the femur neck was considered discordant, and 3 groups (lumbar low [LL] discordance, no discordance [ND], and femur neck low [FL] discordance) were compared. In the discordance group, lumbar radiographs were reviewed to determine the cause of discordance.
Results:
Among 1,220 eligible patients, 130 were excluded due to patient refusal or bilateral hip implantation; therefore, this study included 1,090 patients (271 male and 819 female). The prevalence of LL, ND, and FL was 4.4%, 66.4% and 29.2% in men and 3.9%, 76.1%, and 20.0% women. Mortality was not associated with discordance. The most common causes of discordance were physiological in the LL group and pathological in the FL group for both sexes.
Conclusions
Patients with hip fractures showed lower rates of ND and higher rates of FL compared to the general population. True discordance should be carefully judged for pathological and artifact reasons. The clinical implications of SHD require further investigation.

Intubating patients with a huge, fixed supraglottic mass causing an obstruction of the glottis is difficult to most anesthesiologists. We attempted awake fiberoptic orotracheal intubation assisted by Glidescope(R) Videolaryngoscope (GVL) following topical anesthesia with 4% lidocaine spray and remifentanil infusion. The glottis could not be identified by the GVL view. However, by entering toward the right side of the mass with bronchoscope, the glottis was found. Due to stiffness of the mass, we were unable to further enter the area using the bronchoscope. Alternatively, we attempted to expose the glottis by GVL blade and then successfully intubated the patient by manually pressing the cricoids cartilage. GVL is nonetheless an excellent instrument in airway management compared to fiberoptic bronchoscope for patients with a huge and fixed supraglottic mass.

PURPOSE: Epilepsy affects more than 0.5% of the world's population. It has a large genetic component and is caused by electrical hyperexcitability in the central nervous system. Despite its prevalence, the disease lacks definitive diagnostic serological biomarkers. To identify potential biomarkers for epilepsy by a convenient method, we analyzed the expression of serum proteins, reflecting alterations in the patient's proteomes. METHODS: We compared two-dimensional electrophoretic band patterns of human sera from eight patients with temporal lobe epilepsy (TLE) with those of eight control subjects. The differentially expressed bands were identified using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and electrospray ionization quadrupole time-of-flight mass spectrometry. RESULTS: Twelve proteins were differentially expressed in the TLE group, of which 6 were identified. Expression of haptoglobin Hp2, PRO2675, immunoglobulin heavy chain constant region gamma 2, an unnamed protein, and three unidentified proteins were upregulated in serum from the patients with TLE, whereas those of major histocompatibility complex (MHC) class I antigen, plasma retinol-binding protein precursor, and three unidentified proteins were downregulated in these patients. After resection of the epileptogenic zone, the expressions of MHC class I antigen, immunoglobulin heavy chain constant region gamma 2, two of the downregulated unidentified proteins, and one of the upregulated unidentified proteins returned to the normal range. CONCLUSIONS: The 12 serum proteins in this study are potentially useful biomarkers for the diagnosis and monitoring of TLE.

PURPOSE: Comparing with suture and staple, skin graft fixation with Histoacryl (N-butyl-cyanoacrylate, B.Braun, Germany) has two advantages. Fixation is simple, painless and removal process is unnecessary. There are few reports that compare histoacryl with conventional methods for skin graft fixation in FTSG. However, there are no comparative studies in STSG. The purpose of this study is to show our experience of skin graft fixation with histoacryl in STSG of burn patients. METHODS: This study included those who was burned less than 10% of TBSA and needed STSG. The patients who had underlying disease (DM, hypertension, liver disease, lung disease) were excluded. 29 patients who visited Bestian burn center from January to July 2009 was enrolled in the study. In STSG, skin graft was fixed with histoacryl and authors marked the fixed points with pen. Fixation rate was checked in 7 days after STSG and take rate was checked in 14 days after STSG. RESULTS: The patient group consisted of 7 males and 22 females. The mean extent of burn area was 2.3%. The type of injury consisted of 18 contact, 8 scald, 1 flame, 2 friction. 31 STSG of 29 patients was done. STSG was done at 24th day after burn, the mean area of wound for STSG was 51 cm2. Mean numbers of fixation point with histoacryl per patients were 14.1. 430 of 436 fixation were stable and fixation rate was 98.6%. There was no infection case. Take rate was 99.1% in 14 days after STSG and it took 21 days for wound opening. CONCLUSION: Until now, suture and staple are common methods in skin graft fixation. However, it is disadvantageous that suture and staples should be removed. Histoacryl does not need those process. This study showed that take rate was 99.1% and fixation rate was 98.6% in fixation with histoacryl. In STSG, Skin graft fixation with histoacryl could be alternative methods for suture and staple.

BACKGROUND: The Glidescope Videolaryngoscope (GVL) is a newly developed video laryngoscope. It offers a significantly improved laryngeal view and facilitates endotracheal intubation in difficult airways, but it is controversial in that it offers an improved laryngeal view in normal airways as well. And the price of GVL is expensive. We hypothesized that intubation carried out by fully experienced anesthesiologists using the GVL with appropriate pre-anesthetic preparations offers an improved laryngeal view and shortened intubation time in normal airways. Therefore, the aim of this study was to compare the GVL with the Macintosh laryngoscope in normal airways and to determine whether GVL can substitute the Macintosh laryngoscope. METHODS: This study included 60 patients with an ASA physical status of class 1 or 2 requiring tracheal intubation for elective surgery. All patients were randomly allocated into two groups, GVL (group G) or Macintosh (group M). ADS (airway difficulty score) was recorded before induction of anesthesia. The anesthesiologist scored vocal cord visualization using the percentage of glottic opening (POGO) visible and the subjective ease of intubation on a visual analogue scale (VAS). The time required to intubate was recorded by an assistant. RESULTS: There was a significant increase in POGO when using the GVL (P < 0.05). However, there was no difference in the time required for a successful tracheal intubation using the GVL compared with the Macintosh laryngoscope. The VAS score on the ease of intubation was significantly lower for the GVL than for the Macintosh laryngoscope (P < 0.05). CONCLUSIONS: GVL could be a first-line tool in normal airways.
