We conducted a single-arm prospective study in 50 patients who received the combination of an haploidentical stem cell graft and an unrelated umbilical cord blood unit for the treatment of hematological malignancies. The median time for neutrophil engraftment was 13 days (11-20 days), and for platelets was 15 days (11-180 days). All surviving patients attained complete haploidentical engraftment except three patients who presented a mixed engraftment with increasing cord blood and decreasing haplo mismatch chimerism during the first 4 months after transplantation. The cumulative incidence of grade II-IV acute GVHD was 20% ± 0.327% at day þ 100, and the incidence of chronic GVHD was 19.26% ± 1.0% at 1 year. The 1-year cumulative incidence of relapse was 19.78%±1%, and the TRM was 16.2%±0.54%. At 1 year, overall survival was 78.6%±7.6% and PFS 64.0%±11.0%. The BU/CY-based conditional regimen showed a significant superiority over TBI/CY on PFS (relative risk ¼ 5.012, 95% confidence interval, 1.146-21.927, P ¼ 0.032). In conclusion, the co-infusion of an unrelated cord blood unit may potentially improve the outcome of haploidentical allogeneic hematopoietic SCT.

ObjectiveTo clarify the relationship of skin temperature changes to clinical, radiologic, and electrophysiological findings in unilateral lumbosacral radiculopathy and to delineate the possible temperature-change mechanisms involved.MethodsOne hundred and one patients who had clinical symptoms and for whom there were physical findings suggestive or indicative of unilateral lumbosacral radiculopathy, along with 27 normal controls, were selected for the study, and the thermal-pattern results of digital infrared thermographic imaging (DITI) performed on the back and lower extremities were analyzed. Local temperatures were assessed by comparing the mean temperature differences (ΔT) in 30 regions of interest (ROIs), and abnormal thermal patterns were divided into seven regions. To aid the diagnosis of radiculopathy, magnetic resonance imaging (MRI) and electrophysiological tests were also carried out.ResultsThe incidence of disc herniation on MRI was 86%; 43% of patients showed electrophysiological abnormalities. On DITI, 97% of the patients showed abnormal ΔT in at least one of the 30 ROIs, and 79% showed hypothermia on the involved side. Seventy-eight percent of the patients also showed abnormal thermal patterns in at least one of the seven regions. Patients who had motor weakness or lateral-type disc herniation showed some correlations with abnormal DITI findings. However, neither pain severity nor other physical or electrophysiological findings were related to the DITI findings.ConclusionSkin temperature change following lumbosacral radiculopathy was related to some clinical and MRI findings, suggesting muscle atrophy. DITI, despite its limitations, might be useful as a complementary tool in the diagnosis of unilateral lumbosacral radiculopathy.

ObjectiveTo assess head posture using cervical spine X-rays to find out whether forward head posture is related to myofascial pain syndrome (MPS) in neck and shoulder.MethodsEighty-eight participants who were diagnosed with MPS in neck and shoulder were evaluated in this study. Four parameters (distance among head, cervical spines, and shoulder, and cervical angle) were measured from lateral view of cervical spine X-ray. The location and number of trigger points in the neck and shoulder and symptom duration were evaluated for each patient.ResultsBoth horizontal distances between C1 vertebral body and C7 spinous process and between the earhole and C7 vertebral body were negatively correlated with cervical angle reflecting cervical lordosis (p<0.05). Younger patients had significantly (p<0.05) less cervical angle with more forward head posture. There was no relationship between MPS (presence, location, and number of trigger points) and radiologic assessments (distance parameters and the cervical angle).ConclusionForward head posture and reduced cervical lordosis were seen more in younger patients with spontaneous neck pain. However, these abnormalities did not correlate with the location or the number of MPS. Further studies are needed to delineate the mechanism of neck pain in patients with forward head posture.
