Radiopharmaceutical and also Eu3+ doped gadolinium oxide nanoparticles mediated triple-excited fluorescence imaging along with image-guided surgery.
Metastasis of head and neck squamous cell carcinoma (SCC) to the skin of this region is extremely rare and reported in 1-2% of cases. The cutaneous metastases of head and neck cancers often present as multiple papulonodular lesions; however, sporadic cases of solitary or multiple keratoacanthoma-like lesions are reported. We describe a rare case of cutaneous metastases of laryngeal SCC presenting as multiple eruptive keratoacanthoma-like lesions with concomitant scrofuloderma in an area of previous radiotherapy.The original version of this article unfortunately contained a mistake. Three values in Table 1 were incorrect. In "months of recurrence", range row, the intervals should be in numbers. They should read as 3-83 instead of Mar-83, 9-83 instead of Sep-83 and 3-36 instead of Mar-36. The corrected Table 1 is given below. The original article has been corrected.A 48-year-old man with a pulmonary artery aneurysm was referred to our hospital. Enhanced computed tomography revealed an aneurysm extending from the main trunk to the bilateral pulmonary branch (maximum diameter 6.4 cm) of the artery. Echocardiography revealed moderate pulmonary valve (PV) regurgitation with right ventricle dilatation. Surgery was indicated because of the pulmonary aneurysm and dyspnea on exertion due to moderate PV regurgitation. Intra-operatively, two cusps were found to be normal in shape, whereas a third left-facing cusp was thick and resembled a small ridge. Therefore, we created one neo-cusp with autologous pericardium using a custom-made template and sutured it along a new, predetermined annulus. We then replaced the pulmonary aneurysm with a T-shaped artificial graft. Postoperative echocardiography showed satisfactory movement of the neo-cusp without pulmonary regurgitation and reduced right ventricular size.Using autologous common femoral artery and external oblique muscle fascia is a simple and reliable option for repairing infected aortic pseudoaneurysms. Reoperation of infected pseudoaneurysms is challenging and requires secure aortic repair with complete infection eradication. Here, we report two cases of infected pseudoaneurysms in the ascending aorta cannulation site after cardiac surgeries. Common femoral arteries and fascia were harvested in the same lesion as repair materials. The aortic pseudoaneurysms were repaired under deep hypothermic circulatory arrest. Femoral arterial patches were reinforced with circumferential aponeurosis strips. There was no infection recurrence or repair site dilatation in the long-term follow up of both patients.OBJECTIVE Septal myectomy is the most effective treatment modality for hypertrophic obstructive cardiomyopathy. A retrospective study was conducted to evaluate outcomes of surgical myectomy alone or with concomitant mitral valve procedures. METHODS From December 2011 through December 2016, a total of 41 patients with symptomatic hypertrophic obstructive cardiomyopathy were operated. There were 14 females and 27 males, aged between 18 and 73 years (mean 49.8 years). All patients had drug refractory symptoms (dyspnea, palpitation, chest pain, fainting, limitation of daily physical activities). Twenty-one patients received septal myectomy alone, 10 patients had SM with mitral valve repair and 10 patients had SM with mitral valve replacement. The average follow-up was 38.45 ± 12.18 months. RESULTS Surgery led to symptomatic improvement in all patients. None of the patients were left with NYHA Class III and IV symptoms after surgery. The improvement in left ventricular outflow tract gradient was from 116.65 mmHg preoperatively to 22.47 mmHg. Mean septal thickness decreased from 2.35 to 1.74 cm. Post procedure permanent pacemaker implantation was required for one patient due to complete heart block, and 2 intracardiac devices were implanted due to resistant arrthymia. None of the patients required a repeat procedure during follow-up period. Operative mortality was 2.4%. CONCLUSION Septal myectomy is safe and effective. Concomitant mitral operations do not increase morbidity and mortality.OBJECTIVE Idiopathic interstitial pneumonias (IIPs) are predominantly encountered in the lower lobe, and frequently with concomitant emphysema that is predominantly in the upper lobe. BI-3231 in vitro However, the impact of the resection site on surgical outcomes of lung cancer with IIPs remains unclear. This study was conducted to evaluate the surgical outcome between patients undergoing upper or lower lobe resection. METHODS This retrospective study was performed on 1972 patients who underwent surgical resection for lung cancer at our institute between 2009 and 2018. Review of CT findings revealed that 337 (14.1%) patients had IIPs. Morbidity, mortality, and postoperative pulmonary function test (PFT) were compared between patients who underwent upper or lower lobectomy and stratified by presence or absence of emphysema (CPFE and non-CPFE). RESULTS Surgical mortality and morbidity were not statistically different between the two groups regardless of CPFE. The difference between actual and predicted postoperative PFTs was statistically larger in the upper lobectomy compared to the lower lobectomy among the non-CPFE patients. (FVC p = 0.019, FEV1.0 p = 0.001, %DLCO p = 0.090) CONCLUSIONS Site of the resected lobe in lung cancer is not a prognostic factor of surgical mortality and morbidity in patients with IIPs. However, the impact of upper lobectomy on postoperative respiratory function reduction is larger than lower lobectomy in non-CPFE patients.INTRODUCTION Robotic-assisted techniques are widespread in urology. However, prolonged preparation time for robotic cases hinders operating room (OR) efficiency and frustrates robotic surgeons. Pre-operative times are an opportunity for quality improvement (QI) and enhancing OR throughput. We have previously shown that pre-operative times in robotic cases are highly variable and that increasing patient complexity was associated with longer times. Our objective was to characterize set-up times in robotic urology cases and to determine whether prolongation was due to robot set-up, in particular. MATERIALS AND METHODS Patients undergoing robotic-assisted urology procedures at our academic institution had routine peri-operative collection of demographic data and OR time stamps. Following IRB approval, we retrospectively reviewed set-up times from an OR database. Multivariable analysis was used to assess the influence of independent patient variables-gender (M/F), smoking history, age, BMI, American Society of Anesthesiologists (ASA) Physical Status Classification, and Charlson Comorbidity Index (CCI)-on robot set-up times.
