How to avoid complications of distraction osteogenesis for first brachymetatarsia

Background and purpose Distraction osteogenesis may be used for the treatment of brachymetatarsia. However, few reports have been published on first metatarsal lengthening by this method. We evaluated the complications of distraction osteogenesis for first brachymetatarsia and here we provide a solution

Mislocalization of Visual Stimuli: Independent Effects of Static and Dynamic Attention

Shifts of visual attention cause systematic distortions of the perceived locations of visual objects around the focus of attention. In the attention repulsion effect, the perceived location of a visual target is shifted away from an attention-attracting cue when the cue is presented before the target. Recently it has been found that, if the visual cue is presented after the target, the perceived location of the target shifts toward the location of the following cue. One unanswered question is whether a single mechanism underlies both attentional repulsion and attraction effects. We presented participants with two disks at diagonal locations as visual cues and two vertical lines as targets. Participants were asked to perform a forced-choice task to judge targets' positions. The present study examined whether the magnitude of the repulsion effect and the attraction effect would differ (Experiment 1), whether the two effects would interact (Experiment 2), and whether the location or the dynamic shift of attentional focus would determine the distortions effects (Experiment 3). The results showed that the effect size of the attraction effect was slightly larger than the repulsion effect and the preceding and following cues have independent influences on the perceived positions. The repulsion effect was caused by the location of attnetion and the attraction effect was due to the dynamic shift of attentional focus, suggesting that the underlying mechanisms for the retrospective attraction effect might be different from those for the repulsion effect

Application of a target array Comparative Genomic Hybridization to prenatal diagnosis

<p>Abstract</p> <p>Background</p> <p>While conventional G-banded karyotyping still remains a gold standard in prenatal genetic diagnoses, the widespread adoption of array Comparative Genomic Hybridization (array CGH) technology for postnatal genetic diagnoses has led to increasing interest in the use of this same technology for prenatal diagnosis. We have investigated the value of our own designed DNA chip as a prenatal diagnostic tool for detecting submicroscopic deletions/duplications and chromosome aneuploidies.</p> <p>Methods</p> <p>We designed a target bacterial artificial chromosome (BAC)-based aCGH platform (MacArray™ M-chip), which specifically targets submicroscopic deletions/duplications for 26 known genetic syndromes of medical significance observed prenatally. To validate the DNA chip, we obtained genomic DNA from 132 reference materials generated from patients with 22 genetic diseases and 94 clinical amniocentesis samples obtained for karyotyping.</p> <p>Results</p> <p>In the 132 reference materials, all known genomic alterations were successfully identified. In the 94 clinical samples that were also subjected to conventional karyotyping, three cases of balanced chromosomal aberrations were not detected by aCGH. However, we identified eight cases of microdeletions in the Yq11.23 chromosomal region that were not found by conventional karyotyping. This region harbors the DAZ gene, and deletions may lead to non-obstructive spermatogenesis.</p> <p>Conclusions</p> <p>We have successfully designed and applied a BAC-based aCGH platform for prenatal diagnosis. This platform can be used in conjunction with conventional karyotyping and will provide rapid and accurate diagnoses for the targeted genomic regions while eliminating the need to interpret clinically-uncertain genomic regions.</p

Adenoid cystic carcinoma of the sinonasal tract: treatment results

OBJECTIVES: Malignancies arising from the sinonasal tract, which includes the nose, paranasal sinuses, and nasopharynx, are uncommon. Although adenoid cystic carcinoma (ACC) is the second most common cancer occurring in the sinonasal tract, only few studies have been reported. This retrospective review was performed to identify the clinical features and treatment outcomes of sinonasal ACC. METHODS: Thirty-five patients diagnosed and treated for ACC of the sinonasal tract were included in this study. Medical records, radiographs, and pathologic slides were retrospectively reviewed. RESULTS: In two thirds of the patients, the maxillary sinus was the site of origin and cribriform was the most common histologic subtype (61%). Seventy-one percent of the patients had advanced disease (T3, T4) at the time of diagnosis. Five-year overall survival rate was 86% and treatment failure occurred in 18 patients (51%). Five-year local recurrence rate and distant metastasis rate were 30% and 25%, respectively. Adjunctive radiotherapy appeared to reduce local recurrence. Presence of distant metastasis correlated with decreased 5-year survival (P = .001). Five-year survival rate after development of distant metastasis or local recurrence were 17% and 58%, respectively. CONCLUSIONS: Based on our findings, we suggest that sinonasal ACC be treated by a combined modality of radical surgery followed by postoperative radiation. The prognosis of sinonasal ACC seems to be determined by the presence of distant metastasis

Detection of primary sites in unknown primary tumors using FDG-PET or FDG-PET/CT

<p>Abstract</p> <p>Background</p> <p>Carcinoma of unknown primary tumors (CUP) is present in 0.5%-9% of all patients with malignant neoplasms; only 20%-27% of primary sites are identified before the patients die. Currently, 18F-fluorodeoxy-glucose positron-emission tomography (18F-FDG PET) or PET combined with computed tomography (PET/CT) is widely used for the diagnosis of CUP. However, the diagnostic yield of the primary site varies. The aim of this study was to determine whether PET or PET/CT has additional advantages over the conventional diagnostic workup in detecting the primary origin of CUP.</p> <p>Findings</p> <p>Twenty patients with unknown primary tumors that underwent PET or PET/CT were included in this study. For all patients, the conventional diagnostic workup was unsuccessful in detecting the primary sites. Among 20 patients, 11 had PET scans. The remaining nine patients had PET/CT. In all 20 patients, neither the PET nor PET/CT identified the primary site of the tumor, including six cases with cervical lymph node metastases. The PET and PET/CT revealed sites of FDG uptake other than those associated with known metastases in seven patients, but these findings did not influence patient management or therapy. Two patients had unnecessary invasive diagnostic procedures due to false positive results on the PET or PET/CT.</p> <p>Conclusions</p> <p>Although it is inconclusive because of small sample size of the study, the additional value of PET or PET/CT for the detection of primary sites in patients with CUP might be less than expected; especially in patients that have already had extensive conventional diagnostic workups. Further study is needed to confirm this finding.</p
