  • Thoracic posture-related morphological changes in patients with pectus excavatum versus healthy controls

    　View Summary

    OBJECTIVES. Cases of severe pectus excavatum presenting with worsening cardiopulmonary symptoms in the upright position have been reported. However, the underlying mechanism remains unclear. We evaluated posture-related morphological changes of the thorax in patients with pectus excavatum. METHODS. Chest morphology was evaluated preoperatively using upright and supine computed tomography in 21 patients with pectus excavatum and 35 healthy volunteers. The minimum anterior–posterior thoracic diameter, depression depth, and Haller index on horizontal sections, as well as the T6-12 plumb line distance on sagittal sections, were compared between the 2 positions. RESULTS. In patients with pectus excavatum (median age, 22 years; 18 males and 3 females), the minimum anterior–posterior diameter was smaller (4.5 vs 5.1 cm, P < 0.001) and the Haller index was greater (10.1 vs 6.4, P < 0.001) in the upright position than in the supine position. The T6-T12 plumb line distance was longer in the upright position (2.4 vs 0.8 cm, P < 0.001), while the depression depth showed no significant difference. Healthy volunteers exhibited similar changes. The degree of spinal curvature increased in the upright position due to the anterior shift of the lower thoracic vertebrae, resulting in a shorter anterior–posterior diameter, irrespective of chest wall deformity. One patient with dyspnoea only in the upright position exhibited compression of the right inferior pulmonary vein only on upright computed tomography. CONCLUSIONS. The minimum anterior–posterior diameter is shorter in the upright position. This may explain the worsening of cardiopulmonary symptoms in patients with severe pectus excavatum when in an upright position.

  • Clinical impact of multiple pectus bars on surgical outcomes following pectus excavatum repair

    　View Summary

    OBJECTIVES: The Nuss procedure, a minimally invasive surgery for pectus excavatum, has undergone various improvements. However, the impact of using multiple bars on thoracic shape changes and surgical outcomes remains unclear. METHODS: We retrospectively evaluated patients who underwent the Nuss procedure for pectus excavatum between August 2014 and September 2021. We divided the patients into 2 groups based on the number of bars placed and identified differences in surgical outcomes and morphological characteristics. RESULTS: A total of 225 patients were evaluated, of whom 132 were classified into the ≤2 bar group (using 1 or 2 bars) and 93 into the ≥3 bar group (using 3 or more bars). There was no difference in the preoperative Haller index [median (interquartile range), 4.59 (3.67–6.16) vs 4.67 (4.12–6.14), P ¼ 0.227], and asymmetric excavatum was more frequently observed in the ≥3 bar group (81% vs 51%, P < 0.001). The preoperative sternal torsion angle was larger in the ≥3 bar group, but no difference was found between the 2 groups postoperatively. The incidence of postoperative complications (≥grade 3) was comparable between groups (10% vs 17%, P ¼ 0.105); however, postoperative pleurisy was more frequently observed in the ≥3 bar group (12% vs 4%, P ¼ 0.021). In univariable and multivariable analyses, ≥3 bar placement was the only risk factor for postoperative pleurisy. CONCLUSIONS: The placement of multiple bars (≥3 bars) is useful for the correction of asymmetric pectus excavatum, but attention should be paid to the potential risk of postoperative pleurisy.

    　View Summary

    Cryotherapy and cryoimmunotherapy were performed to 1.5cm femoral tumor that originated from Lewis Lung Cancer cell. Histologically, the area of nonviable tumor was significantly increased in size in cryoimmunotherapy group than cryotherapy group (Average: 88% vs 73%). Our data suggest that cryoimmunotherapy is superior than cryotherapy in local control and the most effective route is local administration. On the other hand, there was no difference in the effectiveness of local control between these three immune checkpoint inhibitors.

  • Hemoglobin vesicles ameriolate allograft airway rejection

    　View Summary

    Acute rejection after lung transplantation is the main risk factor for the development of bronchiolitis obliterans (BO). Hemoglobin-vesicles (HbV) have been developed for use as artificial oxygen carriers and this can provide anti-inflammatory effects and may serve to limit tissue injury in airway transplant. Here, we tested the ability of HbV to prevent airway rejection. Tracheal grafts from BALB/c or C57BL/6 were transplanted to C57BL/6 recipients. Experimental groups were treated with HbV. Histopathological evaluation of luminal obliteration was blindly reviewed. Immunohistochemistry and real-time RT-PCR analyses were performed. Allografts treated with HbV revealed a reduction of thickening in epithelial and subepithelial airway layers at day 7 in orthotopic trachea transplantation model compared with allografts treated with vehicle. There was also a concordant decrease in CD3+ lymphocytes and macrophages in HbV treated allografts.
