Tuberculosis of the pancreas is a rare disorder. The clinical presentation of pancreatic tuberculosis include nonspecific symptoms such as fever, fatigue and weight loss. The radiological features mimic pancreatic malignancy or pancreatitis. So, the diagnosis of pancreatic tuberculosis is very difficult. A 62-year-old man was referred for pancreatic mass. Findings on preoperative imaging modalities were consistent with pancreatic carcinoma, and fine needle aspiration test indicated microcystic adenoma or carcinoma. Pylorus-preserving pancreaticoduodenectomy was done. Final diagnosis was pancreatic tuberculosis combined with microcystic adenoma. We conclude in that patients who have a mass in the pancreas, pancreatic tuberculosis should be considered, particularly in the developing country and immunosuppressed individuals.

This paper reports a rare case of the symptomatic third metatarsal (MT3) - lateral cuneiform (LC) in a 55-year-old male who presented with complaints of severe intermittent pain in his right foot. Plain radiographs and computed tomography scans revealed sclerosis and irregularity at this joint. The intraoperative findings demonstrated a fibrocartilaginous coalition. The pain had improved one year after removing the MT3-LC joint by en bloc and arthrodesis.

BACKGROUND: The Quick Disabilities of the Arm, Shoulder, and Hand questionnaire (QuickDASH) is one of the most widely used questionnaires for assessing functional ability of the patients with upper extremity diseases. Carpal tunnel syndrome (CTS) is the most common neuropathic disease in the upper extremities. The aim of this study was to verify the validity, reliability, and responsiveness of Korean version of QuickDASH questionnaire (K-QuickDASH) in the patients with CTS. METHODS: In total, 83 subjects who underwent open carpal tunnel release (CTR) operation were selected. They fulfilled Korean version of Disabilities of the Arm, Shoulder and Hand questionnaire (K-DASH) and K-QuickDASH at two different time points: before and six months after the surgery. Both criterion-related and construct validities were evaluated using Pearson's correlation coefficient and factor analysis. Internal consistency was estimated using Cronbach's alpha, and test-retest reliability was assessed to verify the reliability of K-QuickDASH using intraclass correlation coefficient (ICC). The standardized response mean and the effect size were analyzed to confirm the responsiveness of the K-QuickDASH in CTS patients. RESULTS: Significant positive correlation was found between K-QuickDASH and K-DASH. All the questionnaire items were categorized into three factors. Acceptable internal consistency was confirmed in three categories of K-QuickDASH. A high test-retest reliability and responsiveness of K-QuickDASH were detected. CONCLUSION: K-QuickDASH in Korean patients with CTS was confirmed to have high degree of validity and reliability, and responsiveness after CTR. Therefore, the K-QuickDASH would be a good evaluation tool for evaluating clinical symptoms and determination of treatment outcomes in the patients with CTS.

Background: The nonunion rate for atypical femoral fractures (AFF) is known to be higher than that for typical fractures of the femur. We performed a meta-analysis to determine the incidence of nonunion necessitating reoperation following fixation for AFF and compare the rates according to the fracture site (subtrochanter or midshaft). Methods: A total of 742 AFFs from 29 studies were included. A proportion meta-analysis utilizing a random-effects model was conducted to estimate the prevalence of nonunion. The outcomes were the incidence of reoperations that included osteosynthesis. To determine the association of nonunion with patient mean age or average duration of bisphosphonate use, meta-regression analysis was done. Results: In proportion meta-analysis, the estimated pooled prevalence of nonunion was 7% (95% confidence interval [CI], 5%–10%) from all studies. There was a significant difference in nonunion rate between the 2 groups (I2 = 34.4%, p = 0.02); the estimated prevalence of nonunion was 15% (95% CI, 10%–20%) in subtrochanteric AFFs and 4% (95% CI, 2%–6%) in midshaft AFFs. From meta-regression analysis, significant correlations were identified between nonunion rate and patient mean age (coefficient:–0.0071, p = 0.010), but not in the average duration of bisphosphonate use (coefficient: –0.0024, p = 0.744). Conclusions A notable disparity existed in the nonunion rate among subtrochanteric AFFs and midshaft AFFs group. Therefore, it is critical for orthopedic surgeons to consider the complexity and challenges associated with AFF and to estimate the proper possibility of nonunion according to the fracture site.

PURPOSE: Hepatobiliary surgery has changed dramatically in recent decades with the advent of laparoscopic techniques. The aim of this retrospective study was to compare survival rates according to stages, adjusting for important prognostic factors. METHODS: A retrospective study of a 17-year period from January 1994 to April 2011 was carried out. The cases studied were divided into two time period cohorts, those treated in the first 9-years (n = 109) and those treated in the last 7-years (n = 109). RESULTS: An operation with curative intent was performed on 218 patients. The 5-year survival rates according to the depth of invasion were 86% (T1), 56% (T2), 45% (T3), and 5% (T4). The number of cases of incidental gallbladder cancer found during 3,919 laparoscopic cholecystectomies was 96 (2.4%). Incidental gallbladder cancer revealed a better survival rate (P = 0.003). Iatrogenic bile spillage was found in 20 perforations of the gallbladder during laparoscopic cholecystectomies, 16 preoperative percutaneous transhepatic gallbladder drainages and 16 percutaneous transhepatic biliary drainages; only percutaneous transhepatic biliary drainage patients showed a significantly lower survival rate than patients without iatrogenic bile spillage (P < 0.034). Chemoradiation appeared to improve overall survival (P < 0.001). Multivariate analysis also revealed that time period, type of surgery, surgical margin, lymphovascular invasion, lymph node involvement, and chemoradiation therapy had significant effects. CONCLUSION: This study found that the prognosis of gallbladder cancer is still determined by the stage at presentation due to the aggressive biology of this tumor. Early diagnosis, radical resection and appropriate adjuvant therapy can increase overall survival.

PURPOSE: The purpose of this study was to review the outcome of fixation of distal humerus fractures using recently-introduced double parallel plate system in sagittal plane. MATERIALS AND METHODS: From May 2004 to June 2008, seventeen patients with distal humerus fractures underwent primary open reduction and internal fixation with double parallel plates. According to the AO classification, there were 2 A3, 2 C1, 7 C2, and 6 C3 type fractures. Outcome assessment was performed by using the Mayo Elbow Performance index (MEPI). RESULTS: At a mean follow up of 18 (range, 12 to 32) months, 4 patients were rated as excellent, 8 as good, and 5 as fair in terms of MEPI. The average arc of elbow flexion after primary operation was 116 (range, 90~140) degrees with a mean flexion contracture of 13 (range, 0 to 30) degrees. One patient required reoperation due to fixation failure and six patients underwent capsulolysis and three patients underwent ulnar nerve neurolysis. The time to begin elbow motion exercise had negative correlation with total elbow range of motion and multiple trauma patients had significantly lower MEPI functional score compared to those without combined injury. CONCLUSION: Double parallel plating allowed adequate fixation for distal humerus fractures regardless of patient age and fracture pattern. Partial ankylosis and unlar nerve compression symptoms were the main causes of reoperation.

PURPOSE: To evaluate the changes in the clinical signs and symptoms of dry eye syndrome before and after cataract surgery according to the main incision location and the type of artificial tears. METHODS: Twenty-four eyes of 17 patients who underwent phacoemulsification and posterior chamber lens insertion from May 2009 to July 2009 were enrolled in the present study prospectively. The main incision location (temporal or superior incision) was determined according to the axis of astigmatism and the postoperative artificial tears (sodium hyaluronate with or without preservatives) were determined randomly. The tear film break-up time (TF-BUT), Schirmer test, esthesiometer, corneal surface grading with Oxford system and ocular surface disease index (OSDI) questionnaire before and 1, 2 and 6 months after surgery were evaluated. The corneal nerve was also analyzed using corneal confocal microscopy (Confoscan 4, Nidek, Italy) before, and 1 and 6 months after surgery. RESULTS: The TF-BUT was significantly longer (p = 0.010) and the OSDI score was significantly lower (p = 0.007) in the patient group with preservative-free sodium hyaluronate than the group with sodium hyaluronate containing preservatives at 6 months after cataract surgery. There were no statistically significant differences according to the main incision location in the sodium hyaluronate without preservatives group. CONCLUSIONS: Symptoms and several signs of dry eye syndrome triggered by cataract surgery decreased with preservative- free artificial tears compared to tears with preservatives.

PURPOSE: To compare the detection rate of the patients with retinal nerve fiber layer (RNFL) defect and the amount of RNFL defect according to the patients' age. METHODS: Retrospective chart reviews of 22,811 subjects, who visited the health care center from January 2009 to December 2009 were performed. The detection rate, location and average amount of RNFL defect and the proportions of the patients who were diagnosed with glaucoma through Humphrey visual field (HVF) test or determined as a glaucomatous optic disc were compared according to the patients' age. RESULTS: The proportions of the patients whose RNFL defect were detected was highest in the patients 60 years old or older (2.3%) and was statistically significant (p = 0.012). However, there was no significant difference among the other age groups (under 40 years: 1.7%, 40 thru 49 years: 1.5%, 50 thru 59 years: 2.0%). The proportions of the patients who were determined as glaucoma through the HVF test or glaucomatous optic disc were also highest in the patients 60 years old or older (1.4%), however, there was no statistically significant difference (p = 0.070) among the age groups (under 40 years: 1.1%, 40 thru 49 years: 0.9%, 50 thru 59 years: 1.2%). CONCLUSIONS: The RNFL defect is likely to be detected in subjects less than 40 years of age and the detection rate is similar to subjects in their 40's and 50's. The use of fundus photography to detect RNFL defect in a health care center is recommended in subjects under 40 years of age.

PURPOSE: To evaluate the predictability of intraocular lens (IOL) power calculations using the IOLMaster and four different IOL power calculation formulas (Haigis, Hoffer Q, SRK II, and SRK/T) for cataract surgery in eyes with a short axial length (AL). METHODS: The present study was a retrospective comparative analysis which included 25 eyes with an AL shorter than 22.0 mm that underwent uneventful phacoemulsification with IOL implantation from July 2007 to December 2008 at Seoul National University Boramae Hospital. Preoperative AL and keratometric power were measured by the IOLMaster, and power of the implanted IOL was determined using Haigis, Hoffer Q, SRK II, and SRK/T formulas. Postoperative refractive errors two months after surgery were measured using automatic refracto-keratometry (Nidek) and were compared with the predicted postoperative power. The mean absolute error (MAE) was defined as the average of the absolute value of the difference between actual and predicted spherical equivalences of postoperative refractive error. RESULTS: The MAE was smallest with the Haigis formula (0.37 +/- 0.26 diopter [D]), followed by those of SRK/T (0.53 +/- 0.25 D), SRK II (0.56 +/- 0.20 D), and Hoffer Q (0.62 +/- 0.16 D) in 25 eyes with an AL shorter than 22.0 mm. The proportion with an absolute error (AE) of less than 1 D was greatest in the Haigis formula (96%), followed by those in the SRK II (88%), SRK-T (84%), and Hoffer Q (80%). CONCLUSIONS: The MAE was less than 0.7 D and the proportion of AE less than 1 D was more than 80% in all formulas. The IOL power calculation using the Haigis formula showed the best results for postoperative power prediction in short eyes.

BACKGROUND: The Korean version of the Michigan Hand Outcomes Questionnaire (K-MHQ) was recently validated; however, the questionnaire's responsiveness as well as the degree to which the instrument is sensitive to change has not been thoroughly evaluated in a specific condition in Koreans. We evaluated the responsiveness of the K-MHQ in a homogenous cohort of patients with carpal tunnel syndrome (CTS) and we compared it with that of the Korean version of the Disability of the Arm, Shoulder, and Hand Questionnaire (K-DASH), which was found to have a large degree of responsiveness after carpal tunnel release for Korean patients with CTS. METHODS: Thirty-seven patients with CTS prospectively completed the K-MHQ and the K-DASH before and 6 months after surgery. The responsiveness statistics were assessed for both the K-MHQ and the K-DASH by using the standardized response mean (SRM), which was defined as the mean change of the original scores after surgery divided by the standard deviation of the change. RESULTS: All domains of the K-MHQ significantly improved after carpal tunnel release (p < 0.001). The SRM for all scales but one (the aesthetics scale) showed large responsiveness of > or = 0.8. The aesthetics scale showed medium responsiveness of 0.6. The combined function/symptom scale of the K-DASH significantly improved after surgery (p < 0.001). The SRM of the K-DASH revealed large responsiveness of 0.9. CONCLUSIONS: The K-MHQ was found to have a large degree of responsiveness after carpal tunnel release for Korean patients with CTS, which is comparable not only to the K-DASH, but also to the original version of the MHQ. The region-specific K-MHQ can be useful for outcomes research related to carpal tunnel surgery, especially for research comparing CTS with various other hand and wrist health conditions.
