RESUMO
STUDY DESIGN: Retrospective study. PURPOSE: We examined the clinical and radiological outcomes of patients who received revision surgery for pseudarthrosis or adjacent segment disease (ASD) following decompression and instrumented posterolateral fusion (PLF). OVERVIEW OF LITERATURE: At present, information regarding the outcomes of revision surgery for complications such as pseudarthrosis and ASD following instrumented PLF is limited. METHODS: This study examined 60 patients who received PLF for degenerative lumbar spinal stenosis and subsequently developed pseudarthrosis or ASD leading to revision surgery. Subjects were divided into a group of 21 patients who received revision surgery for pseudarthrosis (Group P) and a group of 39 patients who received revision surgery for ASD (Group A). Clinical outcomes were evaluated using the visual analogue scales for back pain (VAS-BP) and leg pain (VAS-LP), the Korean Oswestry disability index (K-ODI), and each patient's subjective satisfaction. Radiological outcomes were evaluated from the extent of bone union, and complications in the two groups were compared. RESULTS: VAS-LP at final follow-up was not statistically different between the two groups (p =0.353), although VAS-BP and K-ODI at final follow-up were significantly worse in Group P than in Group A (all p <0.05), and only 52% of the patients in Group P felt that their overall well-being had improved following revision surgery. Fusion rates after the first revision surgery were 71% (15/21) in Group P and 95% (37/39) in Group A (p =0.018). The rate of reoperation was significantly higher in Group P (29%) than in Group A (5%) (p =0.021) due to complications. CONCLUSIONS: Clinical and radiological outcomes were worse in patients who had received revision surgery for pseudarthrosis than in those who had revision surgery for ASD. Elderly patients should be carefully advised of the risks and benefits before planning revision surgery for pseudarthrosis.

PURPOSE: Both column and T-shaped acetabular fractures are frequently presented with difficulty in reduction. Incomplete reduction may cause traumatic arthritis in the hip joint, resulting in inferior clinical outcomes. The purpose of this study is to introduce our wiring technique and to report the clinical and radiological outcomes of such technique. MATERIALS AND METHODS: Eight patients who underwent our proposed technique for having acetabular fracture with displaced quadrilateral plate between March 2013 and December 2014 were enrolled. All patients were followed-up more than 1 year. The wire passer was set up from an anterolateral aspect of the iliac crest to the greater sciatic notch, between the abductor muscle and the periosteum. The quadrilateral plate of acetabular fracture was reduced with wiring. Internal fixation was added to the pelvic brim. An analysis of the clinical and radiological outcomes was performed. RESULTS: Reduction was performed within the 3 mm intra-articular step-off in all patients. The mean duration of union was 11.8 weeks (9-15 weeks). Five patients (62.5%) showed excellent results, and radiologically, three patients (37.5%) showed good results, and seven patients (87.5%) showed better than good results. CONCLUSION: The cerclage wiring fixation technique using a large cerclage passer instrument can be a useful and safe reduction method in some cases of acetabular fractures.

OBJECTIVES: The objective of this study was to examine the perinatal and developmental risk factors of attention-deficit hyperactivity disorder (ADHD) diagnosed with a structured interview among Korean children. METHODS: The current study included 924 children (6-15 years) recruited from schools in five Korean cities or a child psychiatry outpatient clinic of Seoul National University Children's Hospital. The parents of the children completed the structured diagnostic interview for attention-deficit hyperactivity disorder, as well as questionnaires on perinatal and developmental risk factors. RESULTS: Preterm delivery, severe maternal stress during pregnancy, change in primary care taker during the first three years, postpartum depression, and delayed first sentence showed a significant association with ADHD diagnosis. CONCLUSION: These findings suggest that perinatal and developmental factors contribute to development of ADHD in Korean children. Conduct of future research using a prospective design is needed in order to identify the causal relationship between observed risk factors and development of ADHD.

OBJECTIVE: To assess prosthetic use by upper extremity amputees, and their difficulties with prostheses in activities of daily living and occupations. METHOD: This study is based on a survey of 307 subjects, who were using prostheses manufactured in the Center of Prosthetics and Orthotics. The survey questionnaire included items about general demographic characteristics, side and level of amputation, type of prosthesis and its use, and difficulties in the activities of daily living, employment and driving. RESULTS: The most common type of prosthesis was the cosmetic hand type (80.2%). There were no statistically significant correlations between satisfaction with prosthesis and the amputation level or type of prosthesis. The most common difficulties in daily living activities experienced by amputees were lacing shoes, removing bottle-tops with a bottle opener, and using scissors. Only 7.3% of amputees received rehabilitation services. Less than half of the amputees (44.7%) used their prostheses for eight or more hours a day, and 76.9% used their prostheses for regular or irregular cosmetic purposes. After amputation, most of the respondents (69.0%) became unemployed or changed workplaces. CONCLUSION: In our study, respondents preferred cosmetic usage to functional usage. Only 30.0% of respondents reported satisfaction with their prostheses. Many of the amputees had difficulties in complex tasks and either changed jobs or became unemployed. Clerical workers were the occupation group, which was most likely to return to work. The development of a more functional prosthetic hand and additional rehabilitation services are required.

OBJECTIVE: To evaluate characteristic gait patterns of transfemoral amputees who have been using polycentric knee for a long time. METHOD: Subjects were 22 transfemoral amputees using prosthesis for 29.0 years and 23 age-matched healthy adults. The three-dimensional gait analysis was performed. Temporospatial, kinematic and kinetic parameters were measured. RESULTS: Cadence and walking velocity of amputees decreased (p<0.05). Single support period decreased in amputee limb. There were no significant differences in hip flexion moment and power. In amputated limb, knee flexion in loading response was not observed and ankle plantar flexion was less than sound limb and control group. Excessive compensations of amputee side hip joint were not significant. CONCLUSION: Long term polycentric knee unit transfemoral prosthesis users show asymmetry of gait pattern which can increase the risk of musculoskeletal problems. Epidemiologic investigation would be necessary for prevention and proper management.

Aphasia, result from damage of language-dominant area of the brain, usually accompanied hemiparesis due to proximity of language centers and motor control areas. So, global aphasia without hemiparesis is a rare stroke syndrome. We report a case of right handed man with language disturbance after stroke. He showed global aphasia without hemiparesis. We use diffusion tensor image tractography (DTT) for evaluation of global aphasia without hemiparesis. DTT demonstrated that preservation of the corticospinal tract. After speech therapy, he showed improvement of language profile on K-WAB.
RESUMO
Dieulafoy's lesion is a rare cause of severe gastrointestinal bleeding. In most cases, Dieulafoy's lesion is typically found in the stomach within 6 cm from the gastroesophageal junction, but the presence of lesions has also been described throughout the gastrointestinal tract. A jejunal Dieulafoy's lesion is extremely rare, and only a few cases have been reported in the Korean population. We experienced a case of a jejunal dieulafoy's lesion mimicking a submucosal tumor that presented with massive gastrointestinal bleeding. The lesion was diagnosed by the use of double balloon enteroscopy and was then confirmed by a pathological examination of the surgical specimen.

Squamous cell carcinoma of the duodenum is an extremely rare neoplasm worldwide. A 44-year-old female patient was admitted to our institution for abdominal pain, and she was diagnosed with primary squamous cell carcinoma of the duodenum. The duodenal cancer was inoperable due to vascular invasion and regional lymph node metastasis. The patient was treated with palliative chemotherapy, but her disease progressed, and she was eventually referred to a local hospital for supportive care. The prognosis of squamous cell carcinoma of the duodenum is poor compared with that of usual duodenal adenocarcinoma. We report the details of this case of squamous cell carcinoma of the duodenum along with a review of the literature.
