The injury mechanism of traumatic cervical spine injury varies, and Allen et al. divide cervical spine injuries into 6 types based on the direction of external force at the time of injury. In this report, we present 2 cases as Lateral Flexion Stage 2. A 51-year-old male (Case 1) was injured in a traffic accident. His conscious level was JCS III-200, and he was found to have a Frankel Grade of B. X-ray revealed a C5/6 fracture dislocation injury of Lateral Flexion Stage 2. We were unable to obtain good reduction. We planned to perform posterior fusion using a cervical spine pedicle screw but could not perform the procedure due to the patient’s poor general condition. A 32-year-old male (Case 2) was injured as a result of being hit by a steel sheet. He had Frankel Grade D paralysis. X-ray revealed a C5/6 fracture dislocation injury of Lateral Flexion Stage 2. We did not perform manual reduction. We performed posterior fixation, anterior decompression and anterior fixation. Bone union was confirmed, and the patient was able to return to work. In cases of this type of fracture dislocation of the cervical spine, the supporting structures of the spinal column circumferentially rupture and induce high instability. Since closed reduction is sometimes difficult and involves risk, strong internal fixation might be recommended.

A 59-year-old man with myocardial infarction underwent 4-vessel coronary artery bypass grafting. After operation, on the 9th hospital day, fever, dehiscence of the median wound, and pus discharge were observed. Methicillin-resistant Staphylococcus aureus (MRSA) was detected in the wound, and median wound curettage and removal of the sternal bone wire were performed. The infection also involved the substernal area and anterior mediastinum, and a diagnosis of mediastinitis was made. After wound cleansing and antibiotic (vancomycin) administration, inflammatory reactions decreased, and MRSA disappeared from the wound. The wound spontaneously closed, and complete closure required 60 days. On the 75th hospital day, pain from the right shoulder to the neck and numbness in the upper limbs suddenly developed. MRI revealed vertebral body destruction at C5-6, and a diagnosis of cervical osteomyelitis was made. The spinal cord was compressed, and there was a risk of spinal cord injury below the cervical spine. After consultation with orthopedic surgeons, cervical anteroposterior fixation was performed, he improved, and was discharged. We report a patient with MRSA mediastinitis complicated by cervical osteomyelitis who required emergency surgery.

It is often reported that the number of cases of cervical spinal cord injury without fracture resulting from falls have increased in recent years with a aging population. We reviewed the cases of cervical spinal cord injury in the patients who were admitted within two days after the injury to our department between January 2006 and December 2012, The subjects of this study numbered 167 cases;129 males and 38 females. The frequency of occurrence of cervical spinal cord injury, according to reports by the fire departments in the southwestern part of Ibaraki Prefecture is 32.0 per million individuals per year. In our cases under review, fractures were noted in 72 individuals, whereas 95 had no fractures. As to the causes of injury, traffic accidents topped the list with 38.9%, followed by falls with 28.7%, stumbles with 20.4%, and other factors with 12.0%. Cervical spinal cord injury account for 75% of all the cases of spinal cord injury with an incident of 30-40 cases per 100 million individuals per year. In 2011, the incidence of cervical spinal cord injuries resulting from traffic accidents decreased, while that of injuries related to falls increased. Six cases of injury resulting from falls happened during repairs on the damaged houses in the aftermath of the Great East Japan Earthquake of March 2013.

We report a 77-year-old woman who underwent mitral valve repair using leaflet folding plasty for mitral regurgitation due to bilatelal commissural prolapse. A Carpentier prosthetic ring was applied to remodel the annulus and to reinforce repair. Postoperative echocardiography revealed no regurgitation and good mitral valve opening. Leaflet folding plasty is considered to be a simple and effective technique to accomplish mitral valve repair for mitral regurgitation due to commissural prolapse.

A 41-year-old woman with neurofibromatosis (NF) was admitted to our hospital for severe pain and right leg swelling of 5 days duration. Paralysis of the right leg due to compartment syndrome was also recognized. She had been diagnosed as von Recklinghausen's neurofibromatosis, previously. 3 D-computed tomography showed a ruptured anterior tibial artery aneurysm. There was a normal patent posterior tibial artery. Since her complaint of pain was severe, we performed an emergency operation. Under the pneumatic tourniquet technique, the aneurysm was resected, and both the proximal and distal sides of the anterior tibial artery were ligated. A massive hematoma was completely removed. Postoperatively, the dorsalis pedis and posterior tibial pulses remained palpable. The paralysis improved considerably and she was given an ambulatory discharge from our hospital 21 days after the operation. Histological examination revealed proliferating wavy spindle cells infiltrating between the adventitia and mesothelium of the aneurysmal wall and staining positively for S 100 immunoperoxidase.

Background: Necrotizing fasciitis is a rare but severe condition associated with high mortality. We encountered a patient with severe and rapidly progressing necrotizing fasciitis. Patient: A 40-year-old male was hit by a tractor and received a wide laceration wound spanning the length of his posterior thigh. Soon after the accident, the wound was washed and debridement was performed. Two days postoperatively, we observed septic changes in the wound and diagnosed this condition as necrotizing fasciitis. Consequently, the patient's leg was amputated at the thigh. The patient, however, developed toxic shock syndrome after the amputation. Endotoxin adsorption using a polymyxin B-immobilized fiber column was performed for 2 days. Finally, a hip joint amputation was performed after 11 days, following which the patient's general condition gradually improved. Discussion: Treatment for necrotizing fasciitis should be initiated promptly. Early debridement is associated with a significant decrease in mortality. In severe conditions, endotoxin and cytokine removal by blood purification is one of the most effective treatments. Although group A streptococci are widely known as "flesh-eating bacteria," we should also consider a wide variety of pathogenic organisms to be the probable cause of severe necrotizing fasciitis. Conclusion: Management of necrotizing fasciitis requires careful investigation as well as an aggressive therapeutic approach, which may include urgent surgical intervention. In addition to surgery, endotoxin adsorption therapy should be considered.

Purpose: Escitalopram has been inadequately evaluated in cancer patients. Here, we report two patients with advanced cancer who benefited from escitalopram for depression. Case 1: A man aged in his 50s had postoperative recurrence of rectal cancer. He was diagnosed with a major depressive episode according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR). The score of the Hamilton Rating Scale for Depression (HAMD-17) was 20 points. He began treatment with 10 mg/day of escitalopram. His symptoms began to improve at about 14 days, and the HAMD-17 score was 4 points at 23 days, suggesting a marked improvement. Case 2: A woman aged in her 50s had cancer of the external auditory canal. She was diagnosed with a major depressive episode according to DSM-IV-TR. The score of HAMD-17 was 26 points. She began treatment with 10 mg/day of escitalopram. Her symptoms began to improve at 15 days, and the HAMD-17 score at 28 days was 13 points, suggesting a marked improvement. In both cases, serious side effects, clear exacerbation of depression, and withdrawal syndrome due to acute drug deprivation associated with worsening of the symptoms were not noted. Conclusion: Escitalopram is considered a useful drug for depression in patients with advanced cancer.

A total of 120 measurements were made for pulse waveform of the radial artery in 73 male subjects in their twenties to forties. We then calculated the parameters in the four-factor concentrated constant circuit model using the method we had developed. From the waveform of the radial artery, we extracted forms equivalent to those referred to as normal, slippery, and string-like pulses according to the pulse-wave models described in the literature. By comparing these parameters, we could show quantitatively the differences in waveforms and related diagnoses of pulses.

In engineering, when the degrce of distortion of the waveform of the signal is expressed numerically, a coefficient called a distortion factor is used. In order to determine whether or not itis possible to quantify the difference in pulse waveforms in terms of a distortion factor, the authors carried out a Fourier analysis of the pulse waves of 74 cases (74 males between 20 and 40 years of age), calculating the distortion factor of these pulse waves. Employing the pulse wave scale devised by Zhaofu Fei et al, the Ping mai, Hua mai and Xuan mai were differentiated by means of the amplitude ratio of the dicrotic notch to the ejection wave. As a result of a comparison between the distortion factors of these three groups, the authors were successful in quantifying the differences between the wave forms in terms of a distortion factor.

Objective: The hospital is changing its formulary reference from paper-based to intranet. There was concern that both paper-based and intranet versions of the formulary would be necessary. Revising the paper-based hospital formulary each time package inserts are revised is difficult. For your review we report on the creation of the iPhone® electronic formulary which enables rapid off-line formulary retrieval and easy updates while at the same time providing low cost service in a light device.
Methods: The CSV (Comma Separated Value) of the hospital formulary dictionary was made using a standard personal computer. The CSV data file was converted using JAMES2DIC into a HTML file format. Next, the converted HTML file is transformed into the EPWING (Electronic Publishing WING) format using EBStudio. Finally, we forward the EPWING dictionary file from the personal computer to the iPhone®. The retrieval becomes possible by using EBPocket for iOS of EPWING/electronic book viewer software for the iPhone®. The number of items was assumed to be 29 items thought for a lot of inquiries to exist.
Results: We compared the paper-based formulary with the iPhone® electronic formulary. As a result, the iPhone4® electronic formulary shortened the retrieval time, was smaller, lighter, and excellent at a lower price.
Conclusion: The iPhone4® electronic formulary enables the user to perform complex full-text searches and retrieve information at a much higher speed than is possible with paper based formularies. It has the additional advantage of seamless integration and deployment of formulary additions or reference material revisions. We believe we have successfully created a practical electronic formulary.
