Several rhinoplasty and nasal reconstruction procedures require cartilage. Various studies have reported on the nasal septal cartilage as a donor site for Caucasian and Asian populations. However, studies regarding the Thai nasal septal cartilage dimensions are rare. This study aimed to examine the length, height, area, and thickness of the nasal septal cartilage, along with implications of the size and quantity of the available cartilage, for grafting in Thai cadavers.

We analyzed the nasal septal cartilage in 42 Thai cadavers. The length, height, area, and thickness were digitally measured using ImageJ 1.52 software, along with the size and area of the available cartilage for grafting after preserving a 10-mm L-strut. Data were compared between sexes.

The mean height, length, and area of the nasal septal cartilage were 30.96 ± 5.90 mm, 26.13 ± 6.90 mm, and 636.10 ± 196.13 mm
, respectively. The length did not differ significantly between sexes. However, the height and area in male cadavers were greate online Instructions to Authors www.springer.com/00266.
3D computer-simulated technology is becoming popular in China. Rhinoplasty with costal cartilage is a good option for Asians. However, the application of 3D imaging in Asian rhinoplasty with costal cartilage has not been systematically assessed.

To analyze the effect of 3D imaging in Asian rhinoplasty with costal cartilage.

In this study, 44 patients were included and randomly divided into 3D and non-3D imaging groups. Selleck CADD522 We performed a prospective survey on the aesthetic scores for preoperative, simulated, and postoperative images and calculated the relative nasal index scores of patients in both groups. Additionally, surveys on satisfactions with surgical outcomes and doctor-patient communication in both groups were conducted.

The actual postoperative result was well consistent with the preoperative simulation result. The 3D computer simulation did not impact the satisfaction with surgical outcomes but increased that with doctor-patient communication. The 3D computer-simulated technology was an effective tool for doctor-patient communication and surgery planning in Asian rhinoplasty with costal cartilage.

Indocyanine green (ICG) fluorescence imaging is increasingly being used in various areas of abdominal surgery. The constant improvement in the technology enables easy intraoperative use and progressively influences operative decision-making, also in robotically assisted colorectal surgery.

Summation of current evidence on the use of ICG fluorescence imaging in robotically assisted colorectal surgery.

The assessment of evidence is based on acomprehensive literature search (PubMed).

First individual studies (feasibility, case matched, prospective cohort, multicenter phaseII, single center randomized controlled study/trial) showed asignificant reduction in the incidence of anastomotic leakage (AL) after colorectal anastomosis through the use of ICG fluorescence angiography (FA, 9.1% vs. 16.3%; p = 0.04). First feasibility studies demonstrated lymph node detection or navigation as well as ureter visualization.

The ICG-FA reliably detects tissue perfusion, quickly and effectively with few side effects. Ies require further convincing multicenter, randomized controlled trials (mRCT).
Thoracoabdominal esophagectomy still plays a major role in the oncological treatment for esophageal cancer. Minimally invasive procedures were developed to reduce the high rate of postoperative morbidity and mortality without negatively affecting the oncological outcome.

What evidence supports minimally invasive oncological surgery of the esophagus? Do patients benefit from minimally invasive esophagectomy compared to an open approach? Is the reduction of surgical access trauma specifically advantageous?

Review, evaluation and critical analysis of the international literature.

Areduction in postoperative morbidity by decreasing surgical trauma was confirmed by three prospective randomized clinical trials, while showing at least similar oncological outcomes. Diverse retrospective analyses and meta-analyses also came to the same result.

A minimization of surgical access trauma during thoracoabdominal esophagectomy reduces postoperative morbidity compared to conventional open surgery. Recent evidence suggests that oncological outcomes are not altered depending on the surgical approach.

After a very slow development over the last two decades minimally invasive pancreatic surgery has currently gained wider acceptance especially in centers. This is due if nothing else, to the increasing availability of robotic assistance systems, which provide maneuverable instruments as well as a 3‑dimensional and enlarged view. Meanwhile, the technical feasibility for even complex pancreatic resections has been shown. This gives rise to the question whether laparoscopic or robotic techniques can generate equal or better results (evidence) with respect to perioperative morbidity, survival after oncological resection and the quality of life. As with all innovative techniques, which are implemented in surgery, the transferability to a wider audience, teaching methods and cost-effectiveness have to be evaluated. This article presents the current scientific evidence for laparoscopic and robotic pancreatic head and left-sided pancreatic surgery.
An individual dosimetry system is essential for the evaluation of precise doses in nuclear medicine. The purpose of this study was to develop a system for calculating not only absorbed doses but also EQDX(α/β) from the PET-CT images of patients for targeted alpha therapy (TAT), considering the dose dependence of the relative biological effectiveness, the dose-rate effect, and the dose heterogeneity.

A general-purpose Monte Carlo particle transport code PHITS was employed as the dose calculation engine in the system, while the microdosimetric kinetic model was used for converting the absorbed dose to EQDX(α/β). PHITS input files for describing the geometry and source distribution of a patient are automatically created from PET-CT images, using newly developed modules of the radiotherapy package based on PHITS (RT-PHITS). We examined the performance of the system by calculating several organ doses using the PET-CT images of four healthy volunteers after injecting
F-NKO-035.

The deposition energy map obtles us to predict the therapeutic and side effects of TAT based on the clinical data largely available from conventional external radiotherapy.Segmented polyurethanes show extraordinary physicochemical properties, mainly owing to the nature and the chemistry of the hard segment domains. There are yet many inexplicable physiochemical properties of MDI-BDO-based hard polyurethane segments such as the geometry, cis-trans isomerism, electronic structure, chemical reactivity, the inter-hard-segment interactions, and the photo-response. In the present study, it was attempted to develop and validate a model system that would facilitate further research on the structural and chemical properties of the MDI-BDO hard segments. It was found that the trans isomer of urethane bond is more stable than the cis isomer, and it is argued here that thermal transformation from trans to cis not possible due to the high rotational energy barrier. The differences between the calculated IR spectra of the cis and trans isomers are proposed as a powerful differentiation tool. The calculated Fukui indices show that cis and trans isomers are different in their chemical reactivity. The findings of the present study suggest intermolecular and intramolecular pi-stacking and highly plausible two significant types of hydrogen bond types between hard segments. In the present study, a model system for MDI-BDO hard segment was developed and successfully validated via computational experiments. Further calculations done with the new model provided an indispensable understanding of the structure, cis-trans isomerism, reactivity, and intermolecular interactions of the MDI-BDO hard segments. The proposed model can be further improved in the future by incorporating suitable soft segments. In summary, the model system developed and validated in the present study has provided new opportunities to understand and further study the structural and chemical features of the hard segments of the MDI-BDO-based polyurethane.A short ssDNA (Apt-21) rationally truncated from the parent 100 nt As(III) aptamer was used for colorimetric determination of As(III). Apt-21 serves dual functions, i.e., recognition of trace As(III) and regulation of AuNPs dispersion by surface attachment, while gold nanoparticles (AuNPs) functioned as colorimetric signal reporters. Under the optimal conditions, the ratio of the absorbance at 650 nm to 520 nm (A650/A520) of AuNPs changed proportionally with increasing concentration of As(III), which showed a linear relationship within the concentration ranges 1-30 ppb and 30-100 ppb with a detection limit of 0.18 ppb. The feasibility of this assay was demonstrated by determining As(III) in spiked water samples with mean recoveries ranging from 96.5-107.1%. Schematic representation of colorimetric detection of As(III) based on the short ssDNA (Apt-21) and gold nanoparticles (AuNPs).
The role of immunotherapy for metastatic melanoma has expanded over the past decade triggering questions regarding the combination and timing of immunotherapy and radiation for brain metastases. We used the National Cancer Database (NCDB) to see if the time from radiation to immunotherapy in patients with melanoma brain metastases had an impact on survival.

We queried the NCDB from 2010 to 2015 for patients with melanoma brain metastases treated with immunotherapy and stereotactic radiosurgery (SRS). Receiver operator characteristic (ROC) curve analysis was done to determine a timepoint associated with outcome. Cox regression was used to identify predictors of survival. Propensity matching was done to account for indication bias.

We identified 247 patients meeting the above criteria. The median patient age was 62years (27-90) and the vast majority were Caucasian (99%). The median SRS dose was 22Gy (18-24Gy).The median time to SRS was 39days (0-344) and the median time to immunotherapy was 56days (6-454). The ROC analysis revealed 8days from SRS to immunotherapy as associated with outcome. Fifty-six patients had immunotherapy prior to SRS, 30 patients had immunotherapy within 0-7days of SRS, and the remaining 161 had immunotherapy greater than 7days from SRS. Three year survival rates were 21%, 55%, and 35% for those timeframes, respectively (p = 0.0153). Propensity matching of the 0-7day and > 7day groups yielded 28 pairs and Kaplan Meier analysis showed 3year overall survival of 55% and 35%, in favor of immunotherapy within 7days of SRS (p = 0.0357). Multivariable Cox regression identified lack of extracranial disease, more recent year of treatment, and time from SRS to immunotherapy of 0-7days as predictors of improved survival.

Immunotherapy within 7days of SRS shows a possible association with improve outcomes in patients with brain metastases from melanoma.
