Purpose: The purpose of this study was to identify factors influencing chemotherapy-induced peripheral neuropathy among colorectal cancer patients receiving oxaliplatin. Methods: A total of 132 patients hospitalized for chemotherapy were surveyed at K University Hospital in Seoul, Korea. This study was a descriptive causal relationship study using a self-report questionnaire survey method. Correlation and multiple regression analysis between the factors were performed using SPSS 18.0. Results: The regression model was significant (F=31.64, p<.001), which meaned that the experience of chemotherapy-induced peripheral neuropathy among the participants was statistically significant. The factors influencing the chemotherapy-induced peripheral neuropathy were depression (${\beta}=.34$, p<.001), followed by anxiety (${\beta}=.32$, p<.001), medical staff support (${\beta}=-.17$, p=.037) and the level of knowledge of anticancer drugs (${\beta}=-.16$, p=.045). The explanatory power of these factors on the chemotherapy-induced peripheral neuropathy of colorectal cancer patients was 69%. Conclusion: The factors influencing the chemotherapy-induced peripheral neuropathy of colorectal cancer patients receiving oxaliplatin were identified as depression, anxiety, level of knowledge of anticancer drugs and medical staff support.

We investigated perceptual similarity and the difference between client and vendor in information technology (IT) outsourcing projects. Specifically, we focused on each player's perception of how the fit of governance and peripheral knowledge affects the performance of IT project outsourcing. For 107 IT projects, we surveyed both client and vendor in the same IT projects and compared the responses of each side. Through a dyadic analysis, we first found that both client and vendor put more weight on the vendor's peripheral knowledge than that of the client as a positive influencer of project performance. However, regarding the governance style of an IT project, client and vendor showed completely different perspectives. The client believed that the vendor's peripheral knowledge positively contributes to the performance of IT project under the governance of outcome control. However, the vendor showed that its peripheral knowledge creates synergy effects under the governance of process control. Our interpretation of the perceptual similarity and difference between client and vendor delivers managerial implications for businesses that process IT projects.

Purpose: The aim of this study was to compare the effect of training and implementation of a pediatric peripheral intravenous infusion protocol on the nurses' performance and infusion complication rate. Methods: A quasiexperimental study using a posttest comparison of a one group pretest-time series design was utilized. This method was developed to measure nursing knowledge and performance based on a pediatric peripheral intravenous infusion protocol. To calculate the occurrence rate of complications, the number of complications were divided into the number of intravenous insertions. Results: It was shown that the training developed by the study team in 2015 contributed to nurses' increased knowledge, as well as improved job performance. Furthermore, the implementation of the protocol revealed that the number of peripheral intravenous insertions, an invasive procedure, decreased. Additionally, the nursing workload related to pediatric intravenous infusions was reduced. Conclusion: This protocol may contribute to the improved scientific quality and efficiency of nursing management of peripheral intravenous infusions.

Posttraumatic vertigo can be defined as the vertiginous disorder occurred after head and neck trauma without other pre-existing vestibular disorder. Central, peripheral, and combined deficits might cause this condition. Especially, various peripheral vestibulopathies are possible causes of posttraumatic vertigo; benign paroxysmal positional vertigo, temporal bone fracture, perilymphatic fistula, labyrinthine concussion, posttraumatic hydrops, and cervical vertigo. Since the differential diagnosis of the posttraumatic vertigo is often difficult, it is essential to acquire knowledge of their pathophysiology and clinical features. In this review, peripheral vestibulopathy as the possible causes of posttraumatic vertigo were described according to the current literature.

Purpose: The purpose of this study was to investigate foot ulcer risk factors, foot care knowledge, and foot care practice in patients with type 2 diabetes. Method: One hundred fifty type 2 diabetic patients were in and out-patients in a large urban hospital. The data were collected using a self-report questionnaire, chart review and foot examination. The questionnaires were developed by the researchers through the experts consultation and literature review. High risk for foot ulcer was evaluated by peripheral neuropathy(PN), peripheral vascular disease(PVD), and prior foot ulcer. Foot risk scores(FRS) means numbers of present risk factors. Results: 31.3% of subjects show 1 FRS, and 13.3% showed 2 FRS. Mean foot care frequency was 3.5 times per week. There were significant differences in foot care knowledge according to DM education (t=2.96, p=.004) and foot care education (t=3.65, p=.001). There were significant differences in the foot care practice activities according to duration of DM (t=3.48, p=.010) and educational levels. Conclusion: There were high proportion of foot ulcer risk among the patients. It is necessary to screen high risk foot ulcer patients and provide practical education for foot care practice of diabetic patients.

Dizziness can be classified mainly into 4 types: vertigo, disequilibrium, presyncope, and lightheadedness. Among these types, vertigo is a sensation of movement or motion due to various causes. The main causes of peripheral vertigo are benign paroxysmal positional vertigo (BPPV), acute vestibular neuritis (AVN), and Meniere's disease. BPPV is one of the most common causes of peripheral vertigo. It is characterized by brief episodes of mild to intense vertigo, which are triggered by specific changes in the position of the head. BPPV is diagnosed from the characteristic symptoms and by observing the nystagmus such as in the Dix-Hallpike test. BPPV is treated with several canalith repositioning procedures. AVN is the second most common cause of peripheral vertigo. Its key symptom is the acute onset of sustained rotatory vertigo without hearing loss. It is treated with symptomatic therapy with antihistamines, anticholinergic agents, anti-dopaminergic agents, and gamma-aminobutyric acid-enhancing agents that are used for symptoms of acute vertigo. Meniere's disease is characterized by episodic vertigo, fluctuating hearing loss, and tinnitus. It is traditionally relieved with life-style modification, a low-salt diet, and prescription of diuretics. However, diagnosis and treatment of the peripheral vertigo can be difficult without knowledge of BPPV, AVN, and Meniere's disease. This article provides information on the differential diagnosis of peripheral vertigo in BPPV, AVN, and Meniere's disease.

The task for chromosome analysis and diagnosis by experienced cytogenetists are being concerned as repetitive, time consuming job and expensive. For that reason, intelligent agent based on chromosome knowledge base has been established to be able to analyze chromosomes and obtain necessary advises from the knowledge base instead of human experts. That is to say, knowledge base by IF THEN production rule was implemented to a knowledge domain with normal and abnormal chromosomes, and then the inference results by knowledge base could enter the inference data into the database. Experimental data were composed of normal chromosomes of 2,736 patients 'cases and abnormal chromosomes of 259 patients' cases that have been obtained from GTG-banding metaphase peripheral blood and amniotic fluid samples. The completed intelligent agent for chromosome knowledge base provides variously morphological information by analysis of normal or abnormal chromosomes and it also has the advantage of being able to consult with user on chromosome analysis and diagnosis.

The peripheral ossifying fibroma(POF) is a relatively common, non-neoplastic gingival growth that is classified as a reactive hyperplastic inflammatory lesion. The clinical appearance of POF is generally a small, well-circumscribed, focal mass with a sessile or pedunculated base. The pathogenesis of this lesion is uncertain. POFs are believed to arise from cells of the periodontal ligament as hyperplastic growth of tissue that is unique to the gingival mucosa. Approximately 60% of POFs occur in the maxilla, and 55%-60% of all cases occur in the incisor-canine area. Most lesions are less than 2 cm in size. To our knowledge, huge POF of approximately 8 cm in size in the lower posterior edentulous ridge has not been previously described in the English literature. We report an unusually huge POF overlying the lower posterior edentulous ridge mucosa, along with long-term follow up result.

Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis has been reported in Graves' disease patients treated with antithyroid drugs (ATDs), especially propylthiouracil. ATD-induced ANCA-associated vasculitis usually involved the kidneys followed by the respiratory organs and skin. The treatment of ANCA-associated vasculitis induced by ATDs is to stop ATD therapy immediately, which often leads to an overall good prognosis. We report a case of ANCA-associated vasculitis in the peripheral nerves of the lower extremities in a 66-year-old woman who was treated with methimazole (MMI) for Graves' disease. To our knowledge, this is the third case of peripheral nervous system (PNS) involvement of ATD-induced vasculitis and the first case of PNS vasculitis associated with MMI.
