Hypoglossal Nerve* ; Spine*

A recurrent laryngeal nerve injury is known as a complication referring to an anterior cervical spine surgery. However, hypoglossal nerve injury is not well known yet. Herein we report a rare case of a 39-years-old male with a hypoglossal nerve injury after C3/4 osteophyte resection with Smith-Robinson approach. In this case there appeared difficulties of articulation and tongue movement with deviation of the tongue to the left side after the surgery and we diagnosed a hypoglossal nerve injury due to retraction against the nerve during the operation. During the operative approach to the upper cervical spine we had to retract the internal carotid artery and the soft tissue to reach the vertebrae. This retract was the cause of the hypoglossal nerve injury. A gently traction and intermittent release is important to avoid a hypoglossal nerve damage.

Pulmonary embolism (PE) is a common disease with a high mortality rate due to right ventricular dysfunction and underfilling of the left ventricle. We present a case of a 33-year-old man with hemodynamically compromised massive PE. His left atrium was collapsed with marked dilatation of the right atrium and ventricle on multi-detector-row CT scans. The patient was treated with an intracatheter injection of a mutant tissue-type plasminogen activator and subsequently showed clinical and radiological improvements. The small left atrial size in combination with a right ventricular pressure overload was considered to be an adjunctive sign of hemodynamically compromised massive PE.

STUDY DESIGN: A prospective, randomized, controlled study. PURPOSE: The objective of this study was to evaluate the effectiveness of two techniques of skin preparation with povidone-iodine. OVERVIEW OF LITERATURE: Preoperative skin preparation is important for preventing surgical site infection by reducing the bacteria in the surgical area. Povidone-iodine is a commonly used agent for preoperative skin preparation, and further decrease in surgical site infections can be expected by understanding how to apply it more effectively. METHODS: Eighty-nine spine surgery patients were randomly allocated to two groups. In group A, povidone-iodine was applied to the surgical site just before starting the operation; in group B, povidone-iodine was applied several minutes prior to starting the operation and was allowed to dry. We collected samples from the wound edge before suturing, and we compared the rates of positive culture between the two groups. RESULTS: The rate of positive culture was 30.2% (13 out of 43 patients) in group A, and 6.5% (3 out of 46 patients) in group B. This indicates that there was a significant difference in postoperative infection rates between group A and group B. CONCLUSIONS: Because bacteria on the skin appeared significantly reduced by allowing povidone-iodine to dry for several minutes prior to surgery, we recommend this approach to reduce the incidence of postoperative infections.

STUDY DESIGN: Case series. PURPOSE: The objective of this study was to investigate the change in pulmonary function in adult patients with a spinal deformity who underwent spinal corrective surgery. OVERVIEW OF LITERATURE: Degenerative lumbar and/or thoraco-lumbar deformities are is often prominent in adult spinal deformity cases, whereas a thoracic deformity involving the chest wall is inconspicuous. A lumbar spine deformity could affect the pulmonary function; however, few reports have investigated pulmonary function in adult patients with a spinal deformity. METHODS: This study included 14 adult patients with a spinal deformity who underwent posterior corrective fusion (3 males, 11 females; mean age, 67.4 years). We measured percent vital capacity (%VC) and percent forced expiratory volume in 1 second (%FEV1) before surgery and six months after surgery. We investigated the change in pulmonary function after corrective surgery and the correlation between radiographic parameters and pulmonary function. RESULTS: Mean preoperative %VC and %FEV1 values were 99.9% and 79.3%, respectively. Two cases were diagnosed with restrictive impairment, and two cases were diagnosed with obstructive impairment before surgery. %VC improved in the restrictive impairment cases six months after surgery. However, %FEV1 did not improve significantly after surgery in the obstructive impairment cases. CONCLUSIONS: Restrictive impairment was improved in adult patients with a spinal deformity by corrective spinal surgery. However, spinal surgery did not improve obstructive impairment.

BACKGROUND: Bone mineral density (BMD) is the indicator of bone quality in at-risk individuals. Along with the fracture risk assessment tool (FRAX), a quick assessment of BMD from routine radiographs may be useful in the case of lacking X-ray absorptiometry data. This study aimed to investigate the correlation of cortical thickness index (CTI) and canal flare index (CFI) with BMD and FRAX and to evaluate their ability to predict femoral neck BMD (nBMD) and FRAX in the general elderly population. METHODS: A total of 560 volunteers (age ≥ 50 years) who underwent hip-spine X-ray, BMD scanning and FRAX calculation were retrospectively reviewed. CTI and CFI were measured on anteroposterior radiographs and analyzed for their correlation with BMD and FRAX and for their ability to predict nBMD. The ability of CTI to predict osteoporosis status (OPS) and fracture risk status (FRS) was also investigated and the threshold values were calculated. All the analyses were performed separately on male and female subjects. RESULTS: Significant differences in CTI, CFI, nBMD and FRAX between males and females were observed. CTI and CFI demonstrated significant positive correlation with nBMD and FRAX (all p < 0.001) in both males and females. CTI, height, and weight significantly predicted nBMD. CTI statistically predicted OPS and FRS, and the values of 0.56 and 0.62 were computed as CTI thresholds for males and females, respectively. CONCLUSIONS: CTI was significantly correlated with nBMD and it predicted nBMD at good prediction levels. Therefore, CTI may be used as a supportive tool in the assessment of OPS and FRS besides BMD and FRAX in clinical practice.

Performing external beam radiotherapy alone without chemotherapy or brachytherapy for locally advanced cervical cancer with multiple lymph node metastases is challenging. The purpose of this case report is to present the efficacy of high‑dose adaptive extended‑field intensity‑modulated radiotherapy (IMRT) with simultaneous integrated boost (SIB) in treating locally advanced cervical cancer with multiple lymph node metastases. A 67‑year‑old woman with locally advanced squamous cell carcinoma of the uterine cervix was treated by external beam radiotherapy alone due to the refusal of chemotherapy and intracavitary brachytherapy. In order to maximize the efficacy of treatment, extended‑field radiotherapy that includes the paraaortic lymph nodes as well as an adaptive IMRT‑SIB plan, was applied. The treatment was successful, resulting in complete tumor disappearance without severe adverse events. In conclusion, high‑dose adaptive IMRT‑SIB may be an alternative treatment option for locally advanced cervical cancer with multiple lymph node metastases.
