Abstract
Domestic cats are susceptible to infection with at least 11 species of Babesia. In Hong Kong, where dogs are commonly infected with B. gibsoni, a single infection in a cat by a novel species, B. hongkongensis, was reported previously. The aim of this study was to investigate the frequency of Babesia spp. detection in cats in Hong Kong. Residual blood-derived DNA from healthy free-roaming community cats (n = 239), and privately-owned cats with and without anaemia undergoing diagnostic investigations (n = 125) was tested for Babesia spp. DNA using a pan-Babesia PCR targeting mitochondrial Cytochrome B, and a B. hongkongensis specific PCR targeting 18S rRNA. Positive samples were confirmed by sequencing and comparative sequence analysis against the GenBank nucleotide database. Babesia hongkongensis was detected in 4/239 (1.7 %) community cats, and 0/125 (0.0 %) privately-owned cats. Babesia gibsoni was detected in 0/239 community cats and 1/125 (0.8 %) privately-owned cats. Cats infected with B. hongkongensis were clinically healthy at the time of sampling. The B. gibsoni-infected cat was anaemic and thrombocytopenic. Cats in Hong Kong can be infected with B. hongkongensis and B. gibsoni, albeit at low frequency. The tick vector for B. hongkongensis is yet to be identified.

Abstract
BACKGROUND The purpose of this study was to find the factors influencing successful bone union for isolated subtalar arthrodesis in posttraumatic subtalar arthritis following calcaneal fracture. MATERIAL AND METHODS We retrospectively analyzed the rate of successful bone union of 119 cases of isolated subtalar arthrodesis for posttraumatic subtalar arthritis performed at five university hospitals between January 2010 and December 2019. Multivariate logistic regression analysis was used to find the factors associated with successful bone union. Successful bone union was defined as resolution of hindfoot pain with the presence of osseous trabecular bridging involving more than 50% of the posterior facet within 6 months postoperatively. RESULTS There were 77 (64.7%) cases of successful bone union, 11 (9.2%) cases of delayed union, 8 (6.7%) cases of questionable union, and 23 (19.3%) cases of nonunion. Use of fully threaded screws was 5.90 times [odds ratio (OR) = 5.90, 95% confidence interval (CI) = 1.42-24.49, p = 0.02] more likely to achieve successful bone union compared to the use of partially threaded screws. Use of two parallel screws or the two divergent screws were 3.71 times (OR = 3.71, 95% CI = 1.05-13.14, p = 0.04) and 4.65 times (OR = 4.65, 95% CI = 1.23-17.53, p = 0.02) more likely to achieve successful bone union compared to the use of a single screw. Use of cancellous autograft or structural autograft was 4.72 times (OR = 4.72, 95% CI = 1.17-19.06, p = 0.03) and 7.12 times (OR = 7.12, 95% CI = 1.46-34.68, p = 0.02) more likely to achieve successful bone union compared to no graft use. CONCLUSION Use of fully threaded screws, autograft, and two screws compared to a single screw were the factors associated with successful bone union within six postoperative months after subtalar arthrodesis for the posttraumatic arthritis.

Abstract
Tick-borne haemoparasite Babesia gibsoni has been detected rarely in cats, in surveys of apparently healthy animals. In stored blood from a 6-year-old male-neutered domestic shorthair cat in Hong Kong, B. gibsoni DNA was detected retrospectively using PCR for Babesia spp. 18S rRNA and mitochondrial cytochrome B genes, followed by sequencing and basic local alignment search tool (BLAST) analysis. The cat presented with severe haemolytic anaemia and thrombocytopenia. The cat responded to supportive care and glucocorticoids and was clinically normal despite persistent subclinical thrombocytopenia until six months after presentation, when it succumbed to a fatal haemorrhagic episode. Necropsy revealed severe intestinal and pulmonary haemorrhage and hypocellular bone marrow with megakaryocytosis but no other causes of immune-mediated thrombocytopenia (IMTP) or immune-mediated haemolytic anaemia (IMHA). Blood stored on days 158 and 180 tested PCR negative for Babesia spp. This report demonstrates that geographic range of B. gibsoni detection in cats includes Hong Kong. The exclusion of other causes suggests that B. gibsoni might have potentially played a role in triggering immune-mediated disease in this case.

Abstract
OBJECTIVES Diagnosis of flatfoot using a radiograph is subject to intra- and inter-observer variabilities. Here, we developed a cascade convolutional neural network (CNN)-based deep learning model (DLM) for an automated angle measurement for flatfoot diagnosis using landmark detection. METHODS We used 1200 weight-bearing lateral foot radiographs from young adult Korean males for the model development. An experienced orthopedic surgeon identified 22 radiographic landmarks and measured three angles for flatfoot diagnosis that served as the ground truth (GT). Another orthopedic surgeon (OS) and a general physician (GP) independently identified the landmarks of the test dataset and measured the angles using the same method. External validation was performed using 100 and 17 radiographs acquired from a tertiary referral center and a public database, respectively. RESULTS The DLM showed smaller absolute average errors from the GT for the three angle measurements for flatfoot diagnosis compared with both human observers. Under the guidance of the DLM, the average errors of observers OS and GP decreased from 2.35° ± 3.01° to 1.55° ± 2.09° and from 1.99° ± 2.76° to 1.56° ± 2.19°, respectively (both p < 0.001). The total measurement time decreased from 195 to 135 min in observer OS and from 205 to 155 min in observer GP. The absolute average errors of the DLM in the external validation sets were similar or superior to those of human observers in the original test dataset. CONCLUSIONS Our CNN model had significantly better accuracy and reliability than human observers in diagnosing flatfoot, and notably improved the accuracy and reliability of human observers. KEY POINTS • Development of deep learning model (DLM) that allows automated angle measurements for landmark detection based on 1200 weight-bearing lateral radiographs for diagnosing flatfoot. • Our DLM showed smaller absolute average errors for flatfoot diagnosis compared with two human observers. • Under the guidance of the model, the average errors of two human observers decreased and total measurement time also decreased from 195 to 135 min and from 205 to 155 min.

Abstract
BACKGROUND Recurrence is one of the most common complications following hallux valgus surgery. Moreover, hallux varus occurs in cases of overcorrection. We aimed to quantitatively measure, using radiographic examination, the dynamics of the soft tissues that act on deformities (recurrence of valgus and occurrence of varus) after the surgery. METHODS This retrospective single-institution study included 60 patients (98 feet) who underwent hallux valgus surgery between 2009 and 2018. According to radiographic findings of the foot under weightbearing conditions at postoperative month 1, we examined the tendons' pathway and calculated the forces on the first metatarsophalangeal joint, which we termed the deformity force angle (DFA). We compared whether there was a significant difference in DFAs between the groups in which deformities occurred and those in which deformities did not occur after correction. In addition, the DFA was compared to known radiographic measurements of hallux valgus recurrence (hallux valgus angle, distal metatarsal articular angle, intermetatarsal angle, and sesamoid position) to assess association with recurrence. RESULTS We observed a significant difference in the DFA between patients with and without hallux valgus recurrence (P < .001) and between those with and without hallux varus (P < .001) based on standing radiographs taken at a minimum of 6 months postoperation. For predicting the deformities, the areas under the curve were 0.863 (hallux valgus recurrence) and 0.831 (hallux varus occurrence), respectively, which was greater than other factors evaluated. The DFA values greater than 9.5 degrees and less than 5.5 degrees were associated with the recurrence of valgus and occurrence of varus, respectively. CONCLUSION In our study, DFA was associated with hallux valgus recurrence when it exceeded 9.5 degrees and hallux varus when it was less than 5.5 degrees. Moreover, in the hallux valgus surgery we performed, a DFA from 5.5 to 9.5 degrees appeared to be a "safe zone" for preventing early deformity after surgery. LEVEL OF EVIDENCE Level III, prognostic.

Abstract
The purpose of this study was to evaluate cartilage quality after internal fixation of osteochondral lesion of the talus (OLT) using second-look arthroscopies and MRIs. Thirty-four patients underwent internal fixation of OLTs involving large bone fragments. Twenty-one of these patients underwent second-look arthroscopies and 23 patients underwent MRIs postoperatively. The arthroscopic findings were assessed using the International Cartilage Repair Society (ICRS) grading system, and the MRI findings were evaluated using the Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score. Five of the patients who underwent second-look arthroscopies showed normal cartilage, 12 showed nearly normal cartilage, 3 showed abnormal cartilage, and 1 showed severely abnormal cartilage, according to the overall ICRS repair grades. All the patients who achieved bone fragment union showed normal, or nearly normal cartilage upon second-look arthroscopy. The ICRS and MOCART scores were significantly higher for the patients with bone fragment union compared to those with nonunion (ICRS scores: 10.3 ± 1.5 vs. 6.0 ± 2.0, p < 0.001, MOCART score: 88.3 ± 10.0 vs. 39.0 ± 20.4, p < 0.001). Low signal intensities of the bone fragments on preoperative T1-weighted MRIs were not associated with nonunion (Fisher's exact test, p = 0.55), and the signal intensities increased postoperatively to levels similar to the underlying talus when bone union was achieved. Second-look arthroscopy and MRI showed normal, or nearly normal, cartilage after internal fixation of OLTs when bone union was achieved. The nonunion of bone fragments resulted in inferior cartilage quality.

Abstract
There are numerous studies recommending fibular groove deepening in the surgical treatment of peroneal tendon dislocation; however, there are some disadvantages to fibular groove deepening procedures. In this study, we evaluated the results of anatomic reattachment of the peroneal retinaculum without fibular groove deepening as a treatment for traumatic peroneal tendon dislocation. Thirty-six patients with recurrent peroneal tendon dislocation, who underwent retinaculum repair without a fibular groove deepening procedure performed by 2 surgeons between March 2004 and March 2017, were enrolled in this study. Resubluxation of tendon, pain on inversion and eversion power of the ankle were monitored. The range of motion of inversion and eversion were measured and then compared to that of the contralateral side. American Orthopedic Foot and Ankle Society (AOFAS), visual analog scale (VAS), Foot Function Index (FFI) scores were obtained for all patients preoperatively and at the final follow-up. Postoperative complications such as infection, sural nerve injury, and recurrence were monitored. Thirty-four patients fully recovered without resubluxation of tendon. Two patients were injured again while playing soccer 6 months after the surgery and fast running 20 months after the surgery respectively. One patient had sural nerve injury. But the symptom was relieved at 6 months after the surgery. None of the patients had weakness of evertor. None of the patients had limited ankle motion. Mean AOFAS, VAS, FFI score improved significantly (p = .02, .01, .02). In conclusion, for the treatment of recurrent dislocation of the peroneal tendon reattachment of the superior retinaculum only without groove deepening followed by proper rehabilitation is sufficient.

Abstract
BACKGROUND Acute ankle fractures can occur during sports activities, and unstable ankle fractures are commonly treated operatively. However, controversy exists about the optimal time to allow weightbearing. HYPOTHESIS Early weightbearing after the stable fixation of an ankle fracture is not inferior to nonweightbearing in terms of ankle function assessed at 12 months after injury. STUDY DESIGN Randomized controlled trial; Level of evidence, 1. METHODS A total of 258 patients were assessed for eligibility. Of these patients, 194 were randomly allocated to either the early weightbearing group (95 patients who were allowed weightbearing at 2 weeks postoperatively) or the nonweightbearing group (99 patients who were not allowed weightbearing until 6 weeks postoperatively). The primary outcome measure was the mean difference in the Olerud-Molander ankle score (OMAS) between the groups, assessed at the 12-month follow-up examination. The secondary outcome measures were the time to return to preinjury activities and patients' subjective satisfaction. Complications such as hardware loosening or failure, fracture displacement, and nonunion were evaluated. RESULTS The mean difference in the OMAS for the early weightbearing group compared with the nonweightbearing group was 1.6 (95% CI, -1.9 to 5.0) in the intention-to-treat analysis. The lower limit of the 95% CI (-1.9) exceeded the noninferiority margin of -8, indicating that early weightbearing was not inferior to nonweightbearing. The difference in the proportion of patients who were satisfied or very satisfied with their treatment was not statistically significant (84.3% vs 76.2%; P = .19); however, the time taken to return to preinjury activities was shorter with early weightbearing than with nonweightbearing (9.1 ± 3.0 vs 11.0 ± 3.0 weeks; P < .001). No cases of nonunion were observed in either group. CONCLUSION Early weightbearing after the operative treatment of an unstable ankle fracture was not inferior to nonweightbearing in terms of OMAS assessed at 12 months after injury. The patients' subjective satisfaction was similar between the groups, although the time taken to return to preinjury activities was shorter in the early weightbearing group.

Abstract
BACKGROUND The purpose of this study was to compare radiographic outcomes of simultaneous bilateral and unilateral distal chevron metatarsal osteotomy (DCMO) in hallux valgus patients aged ≥60 years. METHODS This retrospective study analyzed consecutive outcomes of simultaneous bilateral DCMO and unilateral DCMO performed between June 2010 and August 2018 in 90 feet of 60 patients. Thirty patients underwent simultaneous bilateral DCMO, and 30 underwent unilateral DCMO. Comparative analysis of radiographic and clinical parameters between a simultaneous bilateral DCMO group (SB) and a unilateral DCMO group (U) was performed. RESULTS Mean age at surgery (65.7±4.8 vs 65.2±5.2 years), mean length of follow-up period (20.0 vs 18.6 months), and preoperative radiographic parameters were similar between the 2 groups (SB vs U). Mean hallux valgus angle (HVA) improved from 34.2 to 5.4 degrees (correction angle SB 28.8 vs U 28.8 degrees). Mean first-to-second intermetatarsal angle improved from 15.8 to 6.8 degrees (correction angle SB 8.9 vs U 8.9 degrees). Hallux varus deformity was observed in 4 feet (SB 3 vs U 1), and mechanical instability with callus formation in 1 foot in the unilateral group. CONCLUSION DCMOs in patients aged ≥60 years were radiographically effective and safe, even performed in one stage bilaterally. Radiographic parameters were similar in patients who underwent simultaneous bilateral and unilateral DCMO. LEVEL OF EVIDENCE Level III, retrospective cohort study.

Abstract
PURPOSE The purpose of this study was to evaluate the radiographic and clinical outcomes of patients with hallux valgus (HV) with concomitant metatarsus adductus (MA) treated with distal chevron metatarsal osteotomy (DCMO), without any procedure for the second or third metatarsal. METHODS A multicentre retrospective study involving four hospitals was conducted. A total of 45 feet from 38 patients who had received DCMO for HV with MA with at least one year post-operative follow-up were analysed. HV angle (HVâ), inter-metatarsal angle (IMâ), MA angle (MAâ), and the lateral sesamoid grade were measured. Foot function index (FFI) and visual analogue scale (VAS) were recorded. Patients were divided into mild (18° ≤ MAâ < 20°) and moderate (20° ≤ MAâ) MA groups, and results were compared. RESULTS The mean HVâ and IMâ improved significantly from 35.1° and 14.4° pre-operatively to 10.6° and 7.1° one year post-operatively (p < 0.001). There were no differences in pre-operative HVâ, IMâ, or the sesamoid grade, and also no difference in post-operative HVâ or the sesamoid grade between mild and moderate MA groups. Only the mean post-operative IMâ showed a difference between the two groups (8.3° vs. 6.3°; p = 0.019). All clauses of FFI and VAS improved significantly (p < 0.001). When the extent of improvement was compared between the two groups, there were no significant differences in any category (p > 0.05). The total rate of recurrence (HVâ ≥ 20°) was 11.1% (5/45), and although the moderate group (4/29, 13.8%) had a higher proportion than the mild group (1/16, 6.3%), this was not statistically significant (p = 0.641). CONCLUSION DCMO for patients with HV with MA had satisfactory radiographic and clinical outcomes with minimal recurrence. Except in cases of severe combined deformity, we recommend performing DCMO alone without any additional procedure or manipulation of the other metatarsals as a viable treatment option.

Abstract
BACKGROUND Internal fixation of an osteochondral lesion of the talus (OLT) can restore the congruency of the talus and maintain the subchondral bone and innate hyaline cartilage. However, OLT that is indicated for fixation is rarely encountered; hence, not many studies report on the results after the procedure. PURPOSE To evaluate the clinical and radiological outcomes after internal fixation of chronic OLT involving a large bone fragment of at least 10 mm in diameter and 3 mm in depth on computed tomography (CT). STUDY DESIGN Case series; Level of evidence, 4. METHODS We retrospectively reviewed the data of 26 patients with OLT treated with internal fixation between August 2014 and April 2018. Of the patients, 15 were male and 11 were female, with a mean age of 16 years (range, 11-29 years). The primary radiological outcome measurement was bone union assessed on the 6-month postoperative CT scan. Clinical outcomes were assessed at a mean of 27.7 months postoperatively. RESULTS Twenty patients (77%) achieved bone union on postoperative CT scan. The mean 100-mm visual analog scale (VAS) improved from 30.5 ± 8.5 preoperatively to 13.4 ± 9.7 postoperatively (P < .001). The mean Foot Function Index (FFI) improved from 30.5 ± 6.7 preoperatively to 13.7 ± 9.8 postoperatively (P < .001). A malleolar osteotomy was not necessary to approach the lesion in 88% of patients. A bone fragment with an irregular margin and low density on the preoperative CT scan was significantly associated with nonunion (odds ratio: 7.67, 95% confidence interval: 2.67 to 22.02, P = .008). The difference in clinical outcomes between patients with skeletally immature ankles and those with skeletally mature ankles was not statistically significant. Patient age did not correlate with postoperative 100-mm VAS (Pearson correlation coefficient, r = -0.07, P = 0.72) or the postoperative FFI (Pearson correlation coefficient, r = -0.05, P = .80). CONCLUSION Internal fixation of an OLT involving a large bone fragment resulted in satisfactory clinical and radiologic outcomes. We found that patients with skeletally immature and mature ankles attained healing at comparable rates after the internal fixation of OLT.

Abstract
BACKGROUND The purpose of this study was to determine whether tolerated weight-bearing in a hard-soled shoe was noninferior to the use of a short leg cast for the treatment of a fifth metatarsal base avulsion fracture, as assessed with use of a 100-mm visual analog scale (VAS) for pain at 6 months after the fracture. METHODS A total of 145 patients were assessed for eligibility. Of these, 96 patients were randomly assigned to either the hard-soled shoe group (46 patients) or the cast group (50 patients). The primary outcome measure was the mean difference on the 100-mm VAS between groups at 6 months after the fracture. Secondary outcome measures included the time to return to preinjury activity and patient-reported satisfaction. Analysis was performed according to both an intention-to-treat basis (i.e., patients were included in the assessment of their assigned treatment arm, even if they crossed over to the other treatment arm prior to completing the 6-month follow-up) and a per-protocol basis (i.e., patients who completed the 6-month follow-up were analyzed according to the treatment they received). RESULTS At 6 months after the fracture, the mean 100-mm VAS was 8.6 ± 7.0 mm in the hard-soled shoe group and 9.8 ± 7.3 mm in the cast group (p = 0.41) according to intention-to-treat analysis. The mean difference in 100-mm VAS between the 2 groups was -1.3 mm (95% confidence interval, -4.3 to 1.8 mm). The upper limit of the 95% confidence interval did not exceed the noninferiority margin of 10 mm, indicating that treatment with the hard-soled shoe was noninferior to treatment with the short leg cast. The proportion of patients who reported satisfaction with their treatment was similar between the hard-soled shoe and cast groups (89.5% compared with 87.5%, respectively; p = 0.79), but the time to return to preinjury activity was significantly shorter in the hard-soled shoe group (37.2 ± 14.4 days compared with 43.0 ± 11.1 days in the cast group; p = 0.04). There were no cases of nonunion in either group. CONCLUSIONS Weight-bearing as tolerated in a hard-soled shoe for a fifth metatarsal base avulsion fracture was noninferior to the use of a short leg cast as assessed with use of a 100-mm VAS at 6 months after the fracture. Patient-reported satisfaction was similar between groups, but the time to return to preinjury activity was shorter in the hard-soled shoe group. LEVEL OF EVIDENCE Therapeutic Level I.

Abstract
OBJECTIVE Recently, two influential articles that reported the association of (hydroxy)chloroquine or angiotensin converting enzyme (ACE) inhibitors and coronavirus disease 2019 (COVID-19) mortality were retracted due to significant methodological issues. Therefore, we aimed to analyze the same clinical issues through an improved research method and to find out the differences from the retracted papers. We systematically reviewed pre-existing literature, and compared the results with those of the retracted papers to gain a novel insight. MATERIALS AND METHODS We extracted common risk factors identified in two retracted papers, and conducted relevant publication search until June 26, 2020 in PubMed. Then, we analyzed the risk factors for COVID-19 mortality and compared them to those of the retracted papers. RESULTS Our systematic review demonstrated that most demographic and clinical risk factors for COVID-19 mortality were similar to those of the retracted papers. However, while the retracted paper indicated that both (hydroxy)chloroquine monotherapy and combination therapy with macrolide were associated with higher risk of mortality, our study showed that only combination therapy of hydroxychloroquine and macrolide was associated with higher risk of mortality (odds ratio 2.33; 95% confidence interval 1.63-3.34). In addition, our study demonstrated that use of ACE inhibitors or angiotensin receptor blockers (ARBs) was associated with reduced risk of mortality (0.77; 0.65-0.91). CONCLUSIONS When analyzing the same clinical issues with the two retracted papers through a systematic review of randomized controlled trials and relevant cohort studies, we found out that (hydroxy)chloroquine monotherapy was not associated with higher risk of mortality, and that the use of ACE inhibitors or ARBs was associated with reduced risk of mortality in COVID-19 patients.

Abstract
PURPOSE To analyze the outcome of distal chevron metatarsal osteotomy (DCMO) with lateral release for moderate to severe hallux valgus patients aged 60 years or more. METHODS Consecutive 77 DCMOs in 54 patients were evaluated. Average age at operation was 65.1 ± 4.3 (range 60~79) years; the mean follow-up period was 20.5 ± 14.2 (range 12~93) months. Hallux valgus angle (HVA), first to second inter-metatarsal angle (IMA), and lateral sesamoid grades were measured. Considering the weak bone quality of the patients, fixation failures such as pin migration, callus formation, delayed union, and first metatarsal bone shortening were reviewed. Osteoarthritis (OA) of the first metatarsophalangeal joint (MTPJ), limitation of 1st MTPJ motion (LOM), and transfer metatarsalgia were also reviewed. RESULTS HVA, IMA, and sesamoid grades were improved at three months and final follow-up. The mean HVA was 36.9° ± 7.0° preoperatively and 6.8° ± 7.1° at final follow-up. The mean correction angle of HVA was 31.3° ± 8.5° at three months and 30.1° ± 8.9° at final follow-up. The mean IMA was 16.3° ± 3.0° pre-operatively and 7.7° ± 2.7° at final follow-up. Hallux varus deformity was observed in three feet. Instability of osteotomy site was observed in one foot. Mean metatarsal shortening length was 1.26 ± 2.1 mm at three month follow-up. There were no cases of transfer metatarsalgia after operation. OA was observed in four feet post-operatively. LOM was observed in ten feet (13.0%). There were no instances of re-fracture or avascular necrosis (AVN). CONCLUSION Despite concerns about aggravation of OA and fixation failure, distal chevron osteotomy with lateral release was safe on patients aged 60 years and over.

Abstract
Desmoplastic fibroblastoma is an uncommon, benign fibrous soft tissue tumor that usually occurs in the arms, shoulders, neck, hands, and feet in the fifth to seventh decades of life. In general, it is commonly located in the subcutaneous tissue and skeletal muscle. The authors report an unusual case of a desmoplastic fibroblastoma mimicking tenosynovial giant cell tumor encasing a tendon of the foot in a 72-year-old woman. Ultrasonography revealed an inhomogeneously hypoechoic lobulated soft tissue lesion completely wrapped around the extensor digitorum longus tendon. Color Doppler study revealed increased vascularity in the internal and peripheral portions of the lesion. Magnetic resonance imaging revealed a well-defined, lobulated soft tissue mass encasing the extensor digitorum longus tendon with predominantly isointense signal with some areas of hypointense signal on T1-weighted images, predominantly hyperintense signal with some areas of hypointense signal on T2-weighted images, and inhomogeneous enhancement on fat-suppressed contrast-enhanced T1-weighted images. Surgical excision was performed, and the mass was diagnosed on pathological examination as a desmoplastic fibroblastoma. There has been no previously published radiologic case of a desmoplastic fibroblastoma encasing a tendon of the foot in the literature.

Abstract
Herpes zoster is a common viral disorder that typically shows characteristic painful skin lesion. Motor neuropathy rarely complicates herpes zoster infection, and it may be overlooked without suspicion. Here, we report a case of a herpes zoster patient who presented with sciatica and paresis, but without the typical skin lesion. The patient was initially misdiagnosed as having other disorders including trauma or spine lesion. Electrodiagnostic study and magnetic resonance imaging (MRI) helped to make an accurate diagnosis and localize the motor nerve involvement of herpes zoster.

Abstract
Background Incomplete sesamoid reduction is a potential risk factor for the recurrence of hallux valgus. The purpose of this study was to radiologically investigate changes in sesamoid position after chevron osteotomy and the open lateral soft tissue procedure. Methods Sixty-eight feet that underwent operative correction for hallux valgus deformity were reviewed consecutively. The hallux valgus angle (HVA), first to second intermetatarsal angle (IMA), tibial sesamoid position (TSP), distance of the fibular sesamoid (DFS), and translation of the metatarsal head (TMH) were evaluated preoperatively and at final follow-up. Results While most parameters were significantly decreased after surgery, no significant change in DFS (correction − 1.45 mm, p = 0.08) was noted. The difference between preoperative and postoperative TSP values (ΔTSP) has a moderately positive correlation with difference in TMH values (ΔTMH) (Rho 0.475, p = .000). Other parameters were similarly correlated. Conclusions First, metatarsal bone realignment reduced the sesamoid, but its position, relative to the second metatarsal axis (DFS), was unchanged. The sesamoid is reduced by the lateral translation of the first metatarsal but not by medial sesamoid migration.

Abstract
PURPOSE As outdoor activities participation increase, Achilles tendon rupture incidence also tends to increase. There are a number of treatment and rehabilitation options for a ruptured Achilles tendon. However, the optimal rehabilitation protocols are still under debate. The purpose of this study is to determine whether early rehabilitation is more effective than conventional rehabilitation. METHODS Medical records of 56 patients who had been treated with open repair after a ruptured Achilles tendon were retrospectively reviewed. 24 patients were treated postoperatively with below knee cast immobilization for four weeks, and they started tolerable weight-bearing rehabilitation at four weeks' follow-up. The remaining 32 patients were managed postoperatively with short leg splint immobilization for two weeks and started the tolerable weight-bearing at two weeks' follow-up. We evaluated the patients several times to identify when the single heel raise was possible and measured the American Orthopedic Foot and Ankle Society (AOFAS) scores and Achilles tendon total rupture scores (ATRS) as a functional outcome. RESULTS The single heel raise test was positive in all patients at the last assessment. But there were no statistically significant differences between the groups (p=0.137). The patients in the Cast group took significantly more time to return to work than did the patients in the Splint group (p=0.032). And AOFAS scores and ATRS were slightly higher in the Splint group than in the Cast group. There were statistically significant differences (p=0.042, p=0.028) between the two groups. CONCLUSION The early rehabilitation did not lead to greater endurance, but it showed better results in the return to work and the Achilles functional score. Early rehabilitation after open repair for patients with a ruptured Achilles tendon is helpful for functional recovery. Type of study / Level of evidence: Therapeutic, Level III.

Abstract
BACKGROUND The impact of chemotherapy-associated liver injury (CALI) on postoperative outcome in patients undergoing partial hepatectomy for colorectal liver metastases (CRLM) remains controversial. The objective of this study was to clarify the effect of CALI (sinusoidal dilatation (SD), steatosis and steatohepatitis) on postoperative morbidity and mortality by investigating a large data set from multiple international centres. METHODS PubMed and Embase were searched for studies published between 1 January 2004 and 31 December 2013 with keywords 'chemotherapy', 'liver resection', 'outcome' and 'colorectal metastases' to identify potential collaborating centres. Univariable and multivariable analyses were performed using binary logistic regression models, with results presented as odds ratios (ORs) with 95 per cent confidence intervals. RESULTS A consolidated database comprising 788 patients who underwent hepatectomy for CRLM in eight centres was obtained. In multivariable analyses, severe SD was associated with increased major morbidity (Dindo-Clavien grade III-V; OR 1·73, 95 per cent c.i. 1·02 to 2·95; P = 0·043). Severe steatosis was associated with decreased liver surgery-specific complications (OR 0·52, 95 per cent c.i. 0·27 to 1·00; P = 0·049), whereas steatohepatitis was linked to an increase in these complications (OR 2·08, 1·18 to 3·66; P = 0·012). Subgroup analysis showed that lobular inflammation was the sole component associated with increased overall morbidity (OR 2·22, 1·48 to 3·34; P = 0·001) and liver surgery-specific complications (OR 3·35, 2·11 to 5·32; P < 0·001). Finally, oxaliplatin treatment was linked to severe SD (OR 2·74, 1·67 to 4·49; P < 0·001). CONCLUSION An increase in postoperative major morbidity and liver surgery-specific complications was observed after partial hepatectomy in patients with severe SD and steatohepatitis. Postoperative liver failure occurred more often in patients with severe SD.

Abstract
Abstract
Background
Although transarterial chemoembolization is recommended as the standard treatment for Barcelona Clinic Liver Cancer stage B hepatocellular carcinoma (BCLC-B HCC), other treatments including liver resection have been used. This study aimed to determine the survival benefit of treatment strategies including resection for BCLC-B HCC compared with non-surgical treatments.
Methods
The nationwide multicentre database of the Korean Liver Cancer Association was reviewed. Patients with BCLC-B HCC who underwent liver resection as a first or second treatment within 2 years of diagnosis and patients who received non-surgical treatment were selected randomly. Survival outcomes of propensity score-matched groups were compared.
Results
Among 887 randomly selected patients with BCLC-B HCC, 83 underwent liver resection as first or second treatment and 597 had non-surgical treatment. After propensity score matching, the two groups were well balanced (80 patients in each group). Overall median survival in the resection group was better than that for patients receiving non-surgical treatment (50·9 versus 22·1 months respectively; P < 0·001). The 1-, 2-, 3- and 5-year overall survival rates in the resection group were 90, 88, 75 and 63 per cent, compared with 79, 48, 35 and 22 per cent in the no-surgery group (P < 0·001). In multivariable analysis, non-surgical treatment only (hazard ratio (HR) 3·35, 95 per cent c.i. 2·16 to 5·19; P < 0·001), albumin level below 3·5 g/dl (HR 1·96, 1·22 to 3·15; P = 0·005) and largest tumour size greater than 5·0 cm (HR 1·81, 1·20 to 2·75; P = 0·005) were independent predictors of worse overall survival.
Conclusion
Treatment strategies that include liver resection offer a survival benefit compared with non-surgical treatments for potentially resectable BCLC-B HCC.

Abstract
BACKGROUND AND PURPOSE Generalized cerebral ischaemia from cardiovascular dysfunction usually leads to presyncopal dizziness, but several studies reported a higher frequency of rotatory vertigo in cardiovascular patients. Whether generalized cerebral ischaemia due to cardiovascular disorders may produce objective vestibular dysfunction was investigated. METHODS Thirty-three patients with orthostatic dizziness/vertigo due to profound orthostatic hypotension and 30 controls were recruited. All participants underwent recording of eye movements during two orthostatic challenging tests: the Schellong and the squatting-standing tests. Most patients had neuroimaging, and patients with abnormal eye movements were subjected to follow-up evaluations. RESULTS Symptoms associated with orthostatic dizziness/vertigo included blurred vision, fainting and tinnitus. Ten (30%) of 33 patients developed rotatory vertigo and nystagmus during the Schellong (n = 5) or squatting-standing test (n = 5). Four of them showed pure downbeat nystagmus whilst five had downbeat and horizontal nystagmus with or without torsional component. Patients with orthostatic nystagmus had shorter duration of orthostatic intolerance than those without nystagmus (1.0 ± 1.6 vs. 11.0 ± 9.7 months, P < 0.001). In two patients, orthostatic nystagmus disappeared during follow-up despite the persistence of profound orthostatic hypotension. CONCLUSIONS Generalized cerebral ischaemia caused by orthostatic hypotension induces rotatory vertigo due to objective vestibular dysfunction. The presence of orthostatic vertigo and nystagmus has an association with the duration of orthostatic intolerance.

Abstract
Pedobarography can quantify static and dynamic foot pressure. Despite an increase in the clinical use of pedobarography, the results and the clinical diagnosis do not always correlate, leading to confusion and misdiagnosis. The authors evaluated the potential of pedobarography to diagnose several diseases associated with abnormal pressure across the plantar surface. The study included 72 patients (96 cases) between January 2009 and August 2012 with symptoms of excessive plantar pressure. The average age was 50.9 years (range, 18-92). Patients had the lesion for an average of 17 months (range, 8-29). Pedobarographic measurements were used to evaluate the compatibility between the highest pressure on pedobarography and the clinical peak pressure with plantar ulcers or calluses. Maximal peak pressure was evaluated by static and dynamic measurements using numeric and graphic measurements in pedobarography. The diagnostic validity of pedobarography was analyzed by comparing clinical peak pressure and pedobarographic measurements. The diagnostic validity of pedobarography was 17.7% to 51% for static measurement and 13.5% to 49% for dynamic measurement. The diagnostic validity of pedobarography was low for intractable plantar keratosis and metatarsal head callus associated with metatarsophalangeal dislocation in rheumatoid arthritis. However, it was 57% to 100% for Charcot arthropathy with midfoot ulcers. When used to compare numeric pressure and graphic peak pressure for each part of the foot, pedobarography showed low diagnostic correlation. Based on the study results, the diagnostic validity of pedobarography is low.

Abstract
BACKGROUND During lower limb lengthening, poor bone regeneration is a devastating complication. Several local or systemic applications have been used to promote osteogenesis, and biologic stimulations are gaining attention, but their utility has not been proven in this setting. QUESTIONS/PURPOSES In patients undergoing bilateral tibial lengthening, we compared those receiving an osteotomy site injection of autologous bone marrow aspirate concentrate (BMAC) plus platelet-rich plasma (PRP) with those not receiving such an injection in terms of external fixator index (time in external fixation divided by amount of lengthening), full weightbearing index (time until a patient was permitted to do full weightbearing divided by amount of lengthening), four cortical healing indexes (time until each cortical union divided by amount of lengthening), and callus shape and type. METHODS Twenty-two patients (44 tibias) undergoing bilateral tibial lengthening enrolled in this randomized trial. Two patients were excluded, one due to insufficient radiographic evaluation and one who was lost to followup, leaving 20 patients (40 segments) for inclusion. Ten patients (20 segments) received BMAC combined with PRP injection (treatment group) and 10 patients (20 segments) received no injection (control group). All patients underwent stature lengthening for familial short stature with the lengthening over nail technique. Autologous BMAC combined with PRP was injected at the tibial osteotomy site at the end of the index surgery. Mean distraction rates were similar between groups (0.75 mm/day in the treatment group versus 0.72 mm/day in the control group; p = 0.24). Full weightbearing was permitted when we observed radiographic evidence of healing at two cortices; this assessment was made by the surgeon who was blinded to the treatment each patient received. Minimum followup was 24 months (mean, 28 months; range, 24-34 months). RESULTS There was no difference in mean external fixator index between groups. However, mean cortical healing indexes (anterior/posterior/medial/lateral) were 1.14/0.81/0.96/0.88 months/cm in the treatment group and 1.47/1.26/1.42/1.22 months/cm in the control group (all p < 0.001), showing faster healing in the treatment group at each cortex. Full weightbearing was permitted earlier in the treatment group than in the control group (index: 0.99 months/cm and 1.38 months/cm, respectively, p < 0.001). Callus shape and type were not different between groups. CONCLUSIONS Autologous BMAC combined with PRP injection at the osteotomy site helped improve bone healing in distraction osteogenesis of the tibia, although the effect size was small. LEVEL OF EVIDENCE Level I, therapeutic study. See Instructions for Authors for a complete description of levels of evidence.

Abstract
BACKGROUND The aim of this study was to investigate the outcomes of cement arthroplasty used as a primary salvage procedure to treat ankle joint destruction. METHODS This study included sixteen patients who underwent primary cement arthroplasty from May 2004 to March 2012 because of an ankle disorder, including intractable infection, nonunion, or a large bone defect or tumor. The mean age of the patients was fifty-seven years (range, twenty-three to seventy-four years), and the mean follow-up period was thirty-nine months (range, fourteen to 100 months). The cement spacer position, cement breakage, osteolysis around the inserted cement, and alignment of the joint were evaluated radiographically. American Orthopaedic Foot & Ankle Society (AOFAS) scores and visual analogue scale (VAS) pain scores were recorded preoperatively and at the time of final follow-up. Functional questionnaires were used to assess the duration for which the patient could walk continuously, use of walking aids, sports activity, consumption of pain medication, and the patient's subjective assessment of the percentage of overall improvement compared with before the cement arthroplasty. RESULTS The cement spacer was retained without breakage for a mean of thirty-nine months (range, fourteen to 100 months). Osteolysis around the cement was observed in one patient at seventy-eight months, and subluxation developed in one patient. The mean AOFAS and VAS pain scores improved from 39 (range, 11 to 71) preoperatively to 70 (range, 47 to 88) postoperatively (p = 0.001) and from 8 (range, 4 to 9) to 3 (range, 1 to 7) (p = 0.001), respectively. At the final follow-up evaluation, nine of the sixteen patients did not require walking aids, ten used no pain medication, and nine were able to walk continuously for more than an hour. One patient complained of persistent pain and was considered to have had a failure of the procedure. CONCLUSIONS Primary cement arthroplasty might be a treatment option for advanced ankle destruction in elderly and less active patients. LEVEL OF EVIDENCE Therapeutic Level IV.

Abstract
Pulmonary alveolar proteinosis is a rare disorder characterized by alveolar accumulation of surfactant phospholipids and protein components. The symptoms and prognosis are extremely variable. Bronchoalveolar lavage fluid and/or transbronchial lung biopsy are useful for diagnosis; surgical lung biopsy is often unnecessary but useful in the focal involvement. We report a case of pulmonary alveolar proteinosis in a 50-year-old woman, confirmed by a video-assisted thoracoscopic surgery biopsy from the initial focal involvement, with normal bronchoalveolar lavage and transbronchial lung biopsy findings.

Abstract
Glomus tumors are rare benign neoplasms. They typically present with a triad of severe pain, point tenderness, and cold sensitivity. Most glomus tumors will form well-circumscribed nodules, and excisional biopsy of masses detected by ultrasonography or magnetic resonance imaging of the lesion can relieve the symptoms. We describe a 30-year-old female patient with nontumorous glomus cell proliferation with clinical symptoms similar to those of glomus tumors. The lesion was treated by exploration and excision, with a satisfactory clinical outcome.

Abstract
BACKGROUND Prior to 1994, plantar fascia ruptures were considered as an acute injury that occurred primarily in athletes. However, plantar fascia ruptures have recently been reported in the setting of preexisting plantar fasciitis. We analyzed risk factors causing plantar fascia rupture in the presence of preexisting plantar fasciitis. METHODS We retrospectively reviewed 286 patients with plantar fasciitis who were referred from private clinics between March 2004 and February 2008. Patients were divided into those with or without a plantar fascia rupture. There were 35 patients in the rupture group and 251 in the nonrupture group. The clinical characteristics and risk factors for plantar fascia rupture were compared between the 2 groups. We compared age, gender, the affected site, visual analog scale pain score, previous treatment regimen, body mass index, degree of ankle dorsiflexion, the use of steroid injections, the extent of activity, calcaneal pitch angle, the presence of a calcaneal spur, and heel alignment between the 2 groups. RESULTS Of the assessed risk factors, only steroid injection was associated with the occurrence of a plantar fascia rupture. Among the 35 patients with a rupture, 33 had received steroid injections. The odds ratio of steroid injection was 33. CONCLUSION Steroid injections for plantar fasciitis should be cautiously administered because of the higher risk for plantar fascia rupture. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
BACKGROUND/AIMS Real-time, convex probe endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is used for the staging of malignant mediastinal lymph nodes. We evaluated the diagnostic efficacy and safety of EBUS-TBNA when used as an initial diagnostic tool. METHODS We retrospectively studied 56 patients who underwent EBUS-TBNA as an initial diagnostic tool between August 2010 and December 2011. Procedure purpose were classified into four categories: 1) intrathoracic masses adjacent to the central airway; 2) enlarged lymph nodes for concurrent diagnosis and staging in suspected malignancy; 3) enlarged lymph nodes in suspected malignancy cases with inability to perform percutaneous core needle biopsy (PCNB); and 4) solely mediastinal masses/lymph nodes in lieu of mediastinoscopy. RESULTS The diagnostic accuracy of EBUS-TBNA regardless of procedure purpose was calculated to be 83.9%. Furthermore, the diagnostic accuracy of malignant disease was significantly higher than benign disease (93.9% vs. 70.6%, p < 0.001). The diagnostic accuracy of EBUS-TBNA for each disease is as follows: tuberculosis, 50%; sarcoidosis, 60%; aspergillosis, 100%; lung abscess, 100%; lung cancer, 93%; and lymphoma, 100%. There were minor complications in seven patients during the EBUS-TBNA procedure. The complications included mild hypoxia and bleeding. CONCLUSIONS In conclusion, EBUS-TBNA is a useful initial diagnostic tool for both benign and malignant diseases. EBUS-TBAN is also a very safe procedure and less invasive compared to mediastinoscopy or PCNB.

Abstract
The purpose of this study was to compare the outcome and complications of endoscopic versus open release for the treatment of de Quervain's tenosynovitis. Patients with this condition were randomised to undergo either endoscopic (n = 27) or open release (n = 25). Visual Analogue Scale (VAS) pain and Disabilities of Arm, Shoulder, and Hand (DASH) scores were measured at 12 and 24 weeks after surgery. Scar satisfaction was measured using a VAS scale. The mean pain and DASH scores improved significantly at 12 weeks and 24 weeks (p < 0.001) in both groups. The scores were marginally lower in the endoscopic group compared to the open group at 12 weeks (p = 0.012 and p = 0.002, respectively); however, only the DASH score showed a clinically important difference. There were no differences between the groups at 24 weeks. The mean VAS scar satisfaction score was higher in the endoscopic group at 24 weeks (p < 0.001). Transient superficial radial nerve injury occurred in three patients in the endoscopic group compared with nine in the open release group (p = 0.033). We conclude that endoscopic release for de Quervain's tenosynovitis seems to provide earlier improvement after surgery, with fewer superficial radial nerve complications and greater scar satisfaction, when compared with open release.

Abstract
Primary aortoenteric fistula (PAEF) is a rare disease with a high mortality rate due to massive hemorrhaging and diagnostic difficulties. Although hemorrhagic regions can be identified by endoscopy, it is difficult to diagnose PAEF by this method. If PAEF is suspected, endoscopic procedure should be terminated and abdominal CT should be performed. Overlooking the herald bleeding of PAEF can lead to massive bleeding and death. An 85-year-old previously healthy male presented with a complaint of melena. Gastrointestinal endoscopy identified a hemorrhagic site in the third portion of the duodenum and endoscopic hemostasis was performed. However, during the procedure, it became apparent that the hemorrhage was probably not the result of a simple duodenal ulceration and abdominal CT was performed immediately. An aortic aneurysm connected to the duodenum was identified, confirming the diagnosis of PAEF. However, the patient died of massive hemorrhaging before an operation could be performed.

Abstract
AIM: To determine the efficacy of a cap-assisted endoscopy (CAE) to completely visualize the ampulla of Vater (AV) in patients failed by conventional endoscopy.
METHODS: A prospective study was conducted on 120 patients > 20 years of ages who visited the Health Promotion Center of Chungbuk National University Hospital for conscious sedation esophagogastroduodenoscopy (EGD) as a screening test from July to October, 2011. First, forward-viewing endoscopy was performed with reasonable effort using a push and pull method. We considered complete visualization of the AV when we could observe the entire AV including the orifice clearly, and reported the observation as complete or incomplete (partial or not found at all). Second, in cases of complete failure of the observation, an additional AV examination was conducted by attaching a short cap (D-201-10704, Olympus Medical Systems, Tokyo, Japan) to the tip of a forward-viewing endoscope. Third, if the second method failed, we replaced the short cap with a long cap (MH-593, Olympus Medical Systems) and performed a re-examination of the AV.
RESULTS: Conventional endoscopy achieved complete visualization of the AV in 97 of the 120 patients (80.8%) but was not achieved in 23 patients (19.2%). Age (mean ± SD) and gender [male (%)] were not significantly different between the complete observation and the incomplete observation groups. Additional short CAE was performed in patients in whom we could not completely visualize the AV. This group included 13 patients (10.9%) with partial observation of the AV and 10 (8.3%) in which the AV was not found. Short CAE permitted a complete observation of the AV in 21 of the 23 patients (91.3%). Patients in whom visualization of the AV failed with short CAE had satisfactory outcomes by replacing the short cap with a long cap. The additional time for CAE took an average of 141 ± 88 s. There were no complications and no significant mucosal trauma.
CONCLUSION: CAE is safe to use as a salvage method to achieve complete visualization of the AV when a regular EGD examination fails.

Abstract
An adult with ulcerative colitis and diabetes presented with a painful, swollen, edematous left foot. Diagnostic images and laboratory tests were inconclusive. Antibiotics were started immediately but aggravated his symptoms, and the laboratory results worsened. His foot was debrided twice per protocol for treating diabetic foot ulcers or cellulitis. After debridement, his condition worsened rapidly. Pyoderma gangrenosum was correctly diagnosed on the basis of massive neutrophilic infiltration detected in the biopsy tissue and because the lesion was well-defined and colored deep red to violet, unlike the bullosis diabeticorum blisters observed in the diabetic foot. His foot improved with systemic corticosteroids and topical wound care, and a skin defect was treated with a skin graft. After 9 months, his foot was well healed. Pyoderma gangrenosum can be diagnosed by careful examination and must be distinguished from an ulcerated diabetic foot lesion.

Abstract
BACKGROUND Transarticular lateral release through a medial incision can avoid a dorsal incision. This study investigated outcomes following hallux valgus correction using transarticular lateral release, distal chevron metatarsal osteotomy and Akin phalangeal osteotomy through one medial incision. METHODS Between June 2004 and May 2009, a single surgeon performed a transarticular lateral release, distal chevron metatarsal osteotomy and Akin phalangeal osteotomy through one medial incision for hallux valgus on a total of 103 feet of 68 patients. The average patient age at the time of surgery was 51 years, and the average followup was 27 months. RESULTS The average preoperative and final followup results were: 1) hallux valgus angle improvement from 29 degrees to 5 degrees, 2) intermetatarsal angle from 13 degrees to 5 degrees and 3) medial sesamoid bone position from 3 to 1 (p < 0.05 for each variable). The average AOFAS scores were improved from 49 to 92, and the VAS pain scores were improved from 7 to 1 (p < 0.05 for both variables). No patient had a serious complication such as infection, avascular necrosis, nonunion, transfer-metatarsalgia, or first metatarsophalangeal joint arthritis. CONCLUSION Hallux valgus correction using transarticular lateral release, distal chevron metatarsal osteotomy and Akin phalangeal osteotomy through one medial incision was found to be effective and safe. The advantages include that the procedure is simple, early ambulation is possible, and there is no dorsal scarring.

Abstract
Invasive pulmonary aspergillosis (IPA) has emerged as a severe infection in patients with immunocompromised hosts. However, recently, several IPA cases, without an apparent predisposition to immunodeficiency, has been reported. A 72-year-old woman was admitted for evaluation of general weakness and poor oral intake. She reported no medical history, except for intraarticular injection of a corticosteroid for joint pain for the duration of two months. A chest radiography revealed multiple cavitary nodules in both lungs. Examination of specimens, obtained by percutaneous needle biopsy, led to a diagnosis of invasive aspergillosis. Brain magnetic resonance imagining revealed numerous peripheral thin enhancing cystic nodules in both cerebral hemispheres. We initiated intravenous administration of amphotercin B. However, the patient died after nine days. Here, we report an invasive aspergillosis case, which involves the lungs and brain after a short period of steroid injection.

Abstract
BACKGROUND We evaluated the clinical characteristics and treatment outcomes of patients with chronic osteomyelitis in the foot and ankle in patients without diabetes. METHODS We reviewed 15 patients treated for chronic osteomyelitis involving the foot and ankle between September 2004 and March 2007. Patients with diabetes mellitus or who were immunocompromised were excluded. The cause of osteomyelitis, sites of occurrence, causative pathogens, and invasion of the adjacent joint(s) were reviewed, then the clinical characteristics were analyzed. Magnetic resonance imaging was performed to clarify the extent of infection and invasion of the adjacent joint. Surgical management included wide debridement, dead space control, and arthrodesis if there was invasion of the adjacent joint. The mean postoperative followup period was 3.3 years, during which recurrences and complications were evaluated. RESULTS Extrinsic causes accounted for 86.7% of the chronic osteomyelitis involving the foot and ankle. The most common cause of osteomyelitis was trauma with ten cases due to complications following fractures or dislocation. Methicillin-resistant Staphylococcus aureus and Pseudomonas were the most common causative pathogens. In 46.7% of the patients, the adjacent joint was involved and an arthrodesis was performed. The mean length of the hospital stay was 39.1 days. The average of number of surgeries was two. Fourteen of 15 patients had no recurrence. CONCLUSION For the successful treatment of chronic osteomyelitis involving the foot and ankle, an arthrodesis based on invasion of the adjacent joint as well as wide debridement and dead space control was successful in this series.

Abstract
We reviewed the outcome of distal chevron metatarsal osteotomy without tendon transfer in 19 consecutive patients (19 feet) with a hallux varus deformity following surgery for hallux valgus. All patients underwent distal chevron metatarsal osteotomy with medial displacement and a medial closing wedge osteotomy along with a medial capsular release. The mean hallux valgus angle improved from -11.6° pre-operatively to 4.7° postoperatively, the mean first-second intermetatarsal angle improved from -0.3° to 3.3° and the distal metatarsal articular angle from 9.5° to 2.3° and the first metatarsophalangeal joints became congruent post-operatively in all 19 feet. The mean relative length ratio of the metatarsus decreased from 1.01 to 0.99 and the mean American Orthopaedic Foot and Ankle Society score improved from 77 to 95 points. In two patients the hallux varus recurred. One was symptom-free but the other remained symptomatic after a repeat distal chevron osteotomy. There were no other complications. We consider that distal chevron metatarsal osteotomy with a medial wedge osteotomy and medial capsular release is a useful procedure for the correction of hallux varus after surgery for hallux valgus.

Abstract
This study was designed to determine the optimal dose of remifentanil required for the successful insertion of Streamlined Liner of the Pharynx Airway (SLIPA) and to compare it to that required for laryngeal mask airway (LMA) insertion in patients receiving a propofol infusion at a standard effect-site concentration. Fifty-eight patients scheduled to undergo general anaesthesia were randomly assigned to either the SLIPA (n = 29) or LMA (n = 29) group. All patients were premedicated with midazolam 0.05 mg x kg(-1) and glycopyrrolate 0.004 mg x kg(-1) intramuscularly. After the administration of lignocaine 1 mg x kg(-1) intravenously, a propofol infusion was started at an effect-site concentration of 3.5 microg x ml(-1) with a remifentanil infusion without a neuromuscular blocking agent. The remifentanil dose was determined by the modified up-and-down method starting in each group at 4 ng x ml(-1). Six minutes after induction, the airway device was inserted. Airway device insertion was classified as 'success' or 'failure' based on patient response. From the isotonic regression analysis and bootstrap distribution, the EC50 of remifentanil for SLIPA and LMA were 0.93 ng x ml(-1) (95% confidence interval [CI] 0.81 to 1.50 ng x ml(-1) and 1.36 ng x ml(-1) (95% CI 1.19 to 2.06 ng x ml(-1)) respectively, and the EC95 for SLIPA and LMA insertions were 1.90 ng x ml(-1) (95% CI 1.39 to 1.95) and 2.43 ng x ml(-1) (95% CI 1.80 to 2.46 ng x ml(-1)) respectively. Using the 83% CIs from the bootstrap distribution, EC50 for SLIPA was significantly less than that of LMA (0.83 to 1.23 vs 1.26 to 2.00, respectively) (P < 0.05). These findings suggest that the insertion of SLIPA needs about a 32% lower depth of anaesthesia than LMA insertion.

Abstract
A completely extruded talus without any remaining soft tissue attachments is extremely rare. The present report describes treatment of a 45-year-old man who sustained a completely extruded talus injury following a rock-climbing fall. Upon admission, the extruded talus was deep-frozen in our bone bank. The open ankle joint underwent massive wound debridement and irrigation for 3 days. Four days later we performed a primary subtalar fusion between the extruded talus and the calcaneus, anticipating revascularization from the calcaneus. However, aseptic loosening and osteolysis developed around the screw and talus. At 12 months post-trauma we performed a tibiocalcaneal ankle fusion with a femoral head allograft to fill the talar defect. Follow-up at 24 months post-trauma showed the patient had midfoot motion, tibio-talar-calcaneal fusion, and was able partake in 4-hour physical activity twice per week.

Abstract
Microsatellite instability (MSI) and frameshift mutations in genes containing nucleotide repeats have been reported in a subset of colorectal and gastric carcinomas. This study describes the analysis of MSI-positive colorectal (39 cases) and gastric carcinomas (36 cases) for the presence of frameshift mutations of the six genes known to be involved in DNA repair and containing mononucleotide repeats in their coding region. Our mutational study of the 75 MSI-positive tumors revealed frequent mutations in hRAD50 (23 cases, 31%), BLM (16 cases, 21%), and hMSH6 (16 cases, 21%); rare mutations in BRCA1 (1 case, 1%) and ATM (3 cases, 4%); and no mutation in NBS1. In contrast, no frameshift mutation was found in 60 MSI-negative colorectal and gastric carcinomas. The mutation of hRAD50, a gene that is involved in the response to cellular DNA damage and forms a complex with hMRE11 and NBS1, has not been reported previously. Our results suggest that frameshift mutations of hRAD50, BLM, and hMSH6 are selected and play a role in the tumorigenesis of colorectal and gastric carcinomas with MSI. The MSI targeting of the hRAD50 and BLM genes represents an additional link between MSI and DNA repair because alteration of these genes could accelerate defective DNA repair.

Abstract
Activity-dependent changes of conduction velocity (CV) and conduction block in single A(delta) fibers of primary afferent neurons were characterized in a rat model of neuropathy (NP). Injured dorsal root (DR) fiber in NP rats exhibited profoundly greater decreases of CV following impulse activity than did DR fiber in normal rats. Activity-dependent conduction block was absent up to 100 Hz of activity rate in DR fiber of NP rats, but was present above 25 Hz in normal rats. Profiles of activity dependence in sciatic fibers were similar in both NP and normal rats. These results suggest that nerve injury may alter activity-dependent hypoexcitability of A(delta) DR fibers. Furthermore, this excitability change may be responsible for the elevated pain perception in neuropathy.

Abstract
Activity-dependent changes of the conduction latency of single A beta fibers of primary afferent neurons were characterized in both neuropathic (L4 and L6 ligated) and normal rats. Activity-dependent increases in conduction latency of dorsal root fibers in neuropathic rats were significantly stronger than those in normal rats. Different profiles of activity dependence were also observed between injured and adjacent intact dorsal root fibers of neuropathic rats. However, activity-dependent latency changes in sciatic nerves distal to the dorsal root ganglion were not different between neuropathic and normal rats. These results suggest that partial nerve injury induces activity-dependent excitability changes in the dorsal root fibers of neuropathic rat and that these changes may be responsible for the altered sensory processing such as those seen in allodynia.

Abstract
The capacity of mitochondria isolated from livers of 5-day-old piglets to convert pyruvate to phosphoenolpyruvate, malate and citrate has been investigated. These mitochondria have a large capacity to flux pyruvate through the pyruvate carboxylase reaction causing an accumulation of malate, citrate and phosphoenolpyruvate. As much as 70% of the pyruvate utilized during state 3 respiration can flux through the pyruvate carboxylase reaction. The data indicate that phosphoenolpyruvate from mitochondria can contribute a significant fraction of the carbon skeletons of pyruvate converted to glucose by piglet liver (estimated to be 30%).

Abstract
Mitochondria from beef liver oxidize isobutyrylcarnitine at approximately 50% the rate of succinate in the presence of rotenone. However, the oxidation rate of isobutyryl coenzyme A in the presence of l(-)-carnitine is very low and can be negligible in both rat and beef liver mitochondria. The limited stimulation of isobutyryl-CoA oxidation by l(-)-carnitine appears to be due to inhibition of isobutyrylcarnitine translocation rather than lack of formation of isobutyrylcarnitine. This conclusion is supported by the fact that: 1) isobutyrylcarnitine oxidation is inhibited by l(-)-carnitine; 2) some oxidation of isobutyryl-CoA is obtained when a low concentration (50 microM) of l(-)-carnitine is used; and 3) under conditions of high isobutyryl-coenzyme A and l(-)-carnitine concentrations (1 mM), isobutyryl-carnitine is produced in near theoretical amounts by these rat liver mitochondria. Other studies demonstrated that less than 25% of the carnitine isobutyryl transferase activity of beef liver mitochondria and rat liver mitochondria is located on the cytosol side of the acylcoenzyme A barrier of these mitochondria.
