OBJECTIVES: In patients with acute aortic dissection involving the arch and the descending aorta (AADA DeBakey type I), performing a total aortic arch replacement with the frozen elephant trunk (FET) procedure for supposedly better long-term results is still controversial. METHODS: From February 2004 to April 2016, 94 patients with AADA DeBakey type I had an FET procedure (80% men, age 58 ± 12 years). During the early period (Group 1, 2004-10), the FET technique was performed using non-branched grafts...

PURPOSE OF REVIEW: Despite nerve-sparing surgery, postoperative shoulder morbidity remains high and significantly impacts patient's quality of life. This review will focus on recent findings of anatomical nuances of the cranial nerve XI (CN XI) along its course in the neck and possible reasons for postoperative morbidity. RECENT FINDINGS: The most recent studies identified three different branching patterns of the CN XI in the neck. In type 1 (66%), the branch for trapezius muscle exits at the posterior border of the sternocleidomastoid muscle (mSCM)...

REVIEW
Falk Roeder, Robert Krempien
Soft-tissue sarcoma (STS) represent a rare tumor entity, accounting for less than 1% of adult malignancies. The cornerstone of curative intent treatment is surgery with free margins, although the extent of the surgical approach has been subject to change in the last decades. Multimodal approaches usually including radiation therapy have replaced extensive surgical procedures in order to preserve functionality while maintaining adequate local control. However, the possibility to apply adequate radiation doses by external beam radiation therapy (EBRT) can be limited in some situation especially in case of directly adjacent organs at risk with low radiation tolerance...

BACKGROUND: Lateral interbody cages have been proven useful in spinal fusions. Spanning both lateral cortical rims while sparing the Anterior Longitudinal Ligament, the lateral interbody cages restore and maintain disc height while adding stability prior to supplemental fixation. The standard approach for their insertion is by a 90-degree lateral transpsoas method. This is relatively bloodless compared to other techniques although has its limitations, requiring neuro-monitoring and being, at times, very difficult at L4/5 due to iliac crest obstruction or an anterior plexus position...

Ernst Wertheim was a pioneer in the history of the surgical treatment of cervical cancer. His English-language manuscript "The extended abdominal operation for carcinoma uteri (based on 500 operative cases)," which was published in 1912, detailed his standardization of the radical hysterectomy and formed the basis of the current treatment for early stage cervical cancer. We contextualize the Wertheim hysterectomy, emphasizing medical advances that allowed for its development and subsequent modification. We then discuss modifications to the originally proposed procedure, including a maximally extended parametrical resection pioneered by Takayama, and the addition of the Taussig en bloc lymph node dissection by Meigs, both of which afforded an improved mortality profile due to decreased disease recurrence...

BACKGROUND AND OBJECTIVES: Spinal cord stimulation (SCS) has been shown to influence pain-related genes in the spinal cord directly under the stimulating electrodes. There is limited information regarding changes occurring at the dorsal root ganglion (DRG). This study evaluates gene expression in the DRG in response to SCS therapy. METHODS: Rats were randomized into experimental or control groups (n = 6 per group). Experimental animals underwent spared-nerve injury, implantation of lead, and continuous SCS (72 hours)...

Femoral nerve blocks (FNB) can provide effective pain relief but result in quadriceps weakness with increased risk of falls following total knee arthroplasty (TKA). Adductor canal block (ACB) is a relatively new alternative providing pure sensory blockade with minimal effect on quadriceps strength. The meta-analysis was designed to evaluate whether ACB exhibited better outcomes with respect to quadriceps strength, pain control, ambulation ability, and complications. PubMed, Embase, Web of Science, Wan Fang, China National Knowledge Internet (CNKI) and the Cochrane Database were searched for RCTs comparing ACB with FNB after TKAs...

BACKGROUND AND OBJECTIVE: Various irradiances have been reported to be beneficial for the treatment of neuropathic pain with near infrared light. However, the mechanistic basis for the beneficial outcomes may vary based on the level of irradiance or fluence rate used. Using in vivo and in vitro experimental models, this study determined the mechanistic basis of photobiomodulation therapy (PBMT) for the treatment of neuropathic pain using a high irradiance. STUDY DESIGN/MATERIALS AND METHODS: In vitro experiments: Cultured, rat DRG were randomly assigned to control or laser treatment (LT) groups with different irradiation times (2, 5, 30, 60, or 120 seconds)...

BACKGROUND AND OBJECTIVES: Due to its consistent vascular and lymphatic anatomy, the vascularized submental lymph node flap is a reliable option for lymphedema treatment. Despite these advantages, flap harvest requires resection of platysma, which may cause a marginal mandibular nerve pseudo-paralysis. The aim of this study was to investigate the donor site morbidity of an innovative platysma-sparing vascularized submental lymph node flap transfer for treating extremity lymphedema. METHODS: Ten patients undergoing platysma sparing submental lymph-node flap harvest were prospectively enrolled in the study and compared with a control group of 10 patients who underwent standard submental lymph-node flap harvest...

PURPOSE: To calculate the delivered dose for head and neck SBRT patients using pre-treatment images. This delivered dose was then used to determine the viability of 2.5 mm margins. METHODS: Daily cone beam CTs (CBCTs) were collected for 20 patients along with a planning CT, planned dose, and planning structures. The day 1 CBCT was aligned to the planning CT using the treatment shifts (six degrees of freedom) and then the dose and contours were transferred to the CBCT...

PURPOSE: Thinning of the cerebral cortex has been observed in patients treated with fractionated partial brain radiation therapy and may contribute to cognitive decline following treatment. The extent of this thinning is dose-dependent, and was shown comparable to that of neurodegenerative diseases such as Alzheimer's disease at one year post-therapy. This study investigates whether 4π radiotherapy can enable better sparing of the cortex and other critical structures when compared to conventional clinical IMRT plans...

PURPOSE: Recurrent chordomas are difficult to control locally. This dosimetric study investigates the feasibility of dose escalation to hypoxic regions, visualized on FMISO-PET, while respecting the dose constraints to the neighboring normal tissues/organs. We propose to deliver a higher dose to the areas of hypoxia (84.5Gy) using IMPT with the goal of improving local control. METHODS: We currently have four patients with hypoxic subvolumes (HSV) greater than 10cc from the FMISO-PET image...
