Journal of Korean Academy of Fundamental Nursing 2005;12(2):215-222
PURPOSE: To identify the incidence of cutaneous injury in clinical nurses. METHOD: From Feb.1 to 28, 2005, 276 clinical nurses were surveyed by questionnaire. RESULTS: 1. Of the nurses, 53.6% had at least one incidence of cutaneous injury, and the mean number of injuries was 1.34. A higher incidence rate for cutaneous injury was found in nurses who were under the age of 25, unmarried and who had less than 3 years career experience. 2. The major causes of injury were syringe needles at 65.0%, and medical instrument were next followed by sharp objects or blades. The injuries occurred when the nurses were rearranging equipment after care (25.2%), taking blood samples (22.8%), separating syringes and needles (17.1%), during surgical operations (14.2%), and distribution of medications, treatments and recapping of needles (5.7% each). The hands were the most common body parts injured, and the most prevalent pathogens contaminating the instruments causing the injury were HBV, syphilis, HCV and HIV in that order. 3. Of the injured nurses, 77.9% did not report the accident and 25.8% did not receive any treatment because there were no pathogens, it was a bother or there was difficulty reporting the incident. CONCLUSION: To reduce cutaneous injuries, intensive training and supervision may be needed for those of nurses under the age of 25, unmarried and with less than 3 years career experience.

Cytologic findings of malignant cells obtained by fine needle aspiration from a huge retroperitoneal malignant fibrous histiocytoma were described. The smears contained numerous malignant cells, isolated or in clusters, in a bloody background. The malignant cells had abundant pleomorphic foamy or acidophilic cytoplasm with occasional multilobated vesicular nuclei and prominent nucleoli. Dual differentiation, both histiocytic and fibroblastic types, and neutrophilic inflammatory background were diagnostic of this neoplasm. The report indicated that study of aspiration cytology specimen from a soft tissue tumor was a valuable adjunct to histologic examination.

For the nonunion of humeral shaft, there have been many methods of treatment. We are aimed to analyse the causes of nonunion of humeral shaft fracture and present the direction of treatment. We reviewed total 21 cases which were diagnosed as delayed or nonunion of humeral shaft and analysed the causes. l. Initial method of treatment was surgical in 19 out of 21 cases. Among these 19 cases, 14 cases were operated with internal fixation with plate and screw. 2. The most common cause of nonunion was inadequate internal fixation in 26 cases(81%) in which were unstable fixation in 13 cases, choice of inadequate internal fixator in 11 cases, and failure of operative technique in 2 cases. Other causes were distraction between fracture fragments in 4 cases(13%) and open comminuted fracture in 2 cases. 3. Eighteen cases of established nonunion due to inadequate internal fixation were treated by rigid fixation with longer and broader plate and bone graft, and 1 case interlocking IM nailing, 1 case Ender nailing and 1 case bone graft only. 4. Union was obtained in all cases at least in 5 months. And there were no specific complications. In conclusion, surgeons should contemplate the operative indication and principles in primary treatment. In treatment of nonunion, surgeons should treat by more longer and broder internal fixator and additional bone graft.

The cytologic findings in fine needle aspiration of a case of myxoid liposarcoma of the mediastinum are described. The smear and cell block of the aspirate revealed solid clusters with background of amorphous material and scattered single tumor cells. The clusters were moderately cellular and consisted of atypical lipoblasts in varying stages of differentiation and delicate plexiform capillaries. Good correlation was found between the histologic and cytologic findings in the fine needle aspirates. The differential diagnosis between myxoid liposarcoma and other myxoid soft tissue tumors is discussed,

This study examined factors related to high fear of coronavirus disease 2019 (COVID-19) infection in healthcare workers (HCWs) in COVID-19 dedicated teams. We assigned 371 HCWs to low, medium, and high COVID-19 infection fear groups, and investigated factors associated with COVID-19 infection fear. High COVID-19 infection fear was significantly associated with being a woman and poor professional quality of life. High COVID-19 infection fear group had higher burnout levels and secondary traumatic stress scores than the low and medium fear groups. These findings deepen our understanding of risk factors for and psychological outcomes of COVID-19 infection fear in HCWs.

OBJECTIVE: Alendronate, a widely used bisphosphonates, acts to inhibit bone resorption by interfering with the activity of osteoclasts. Recently, it has been reported that alendronate also may increase bone proliferation and osteoblastic differentiation. However, little is known about mechanism of the action of alendronate on osteoblast differentiation, especially in transcription level. Inhibitors of DNA binding/ differentiation (Ids) are helix-loop-helix (HLH) transcription factors and play an important role in BMP-induced osteoblast lineage-specific differentiation. Therefore, this study was aimed to investigate the effect of alendronate on osteoblast differentiation and expression of Id-1 and Id-2. METHODS: MC3T3-E1, pre-osteoblast cell line, were treated with alendronate of various concentrations (10(-9) M-10(-4) M) and time periods (24, 48 and 72 hours). And then, the effect of alendronate on osteoblast differentiation was examined by alkaline phosphatase (ALP) activity and RT-PCR for osteoblast differentiation markers such as ALP, type 1 collagen (Col 1), and osteocalcin (OCN). The expressions of Id-1 and Id-2 were measured by RT-PCR. RESULTS: Alendronate treatment increased not only ALP activity, but also expressions of ALP, Col 1, and OCN. Also, alendronate treatment up-regulated the mRNA levels of Id-1 and Id-2 genes. This alendronate-induced osteoblastic differentiation is more effective in lower doses rather than high doses. CONCLUSION: This study shows that the expression of transcription factor Id-1 and Id-2 was increased in a dose-dependent manner during alendronate-induced osteoblast differentiation.

PURPOSE: This study was intended to investigate the migrating motor complex (MMC) changes after ileal bypass in ex-vivo mouse models. METHODS: Partial (side-to-side) and total bypass (occlusion of proximal part of bypassed loop) were performed on ileums of female Institute of Cancer Research mice. After 2 and 4 weeks, the bypassed segments were harvested and MMCs were recorded at 4 different sites ex-vivo. Amplitude, duration, interval, direction of propagation, and the area under the curve (AUC) of MMCs were measured and compared to those of the controls. RESULTS: In control mice (n = 7), most MMCs propagated aborally (91.1%). After 2 weeks of partial bypass (n = 4), there was a significant decrease in both amplitude and AUC, and orally-propagating MMCs increased significantly (45%, P = 0.002). Bidirectional MMCs (originating in the bypassed loop and propagating in both directions) were also observed (10%). The amplitude of the MMCs remained decreased at 4 weeks after partial bypass (n = 4), and neither the AUC nor the direction of propagation showed significant changes compared to 2 weeks. Similarly, in the total bypass model, both the amplitude and AUC of the MMCs decreased significantly compared to controls. In contrast to partial bypass, 95% of the MMCs within the bypassed loop propagated aborally after 2 weeks (n = 6), which was similar to the control state. After 4 weeks (n = 5), however, MMCs either lost their temporal relationship or completely disappeared. CONCLUSION: The changes in propagation direction of the MMCs in the partially bypassed loop may contribute to stagnation of bowel contents and the development of blind loop syndrome.

The glomus tumor is a distinct neoplasm composed of modified perivascular smooth-muscle cells identical to those described in the glomus body. Malignant glomus tumor, also referred to as glomangiosarcoma, is exceedingly rare. It has been subdivided into locally infiltrative glomus tumor, glomangiosarcoma arising in a benign glomus tumor, and glomangiosarcoma arising in de novo. A few cases of malignant glomus tumor arising in a benign glomus tumor have been reported. A 55-year-old man underwent resection of a solitary nodule in the right shoulder area. The tumor was biphasic with a typical benign glomus tumor at the periphery and the central sarcomatous area composed of oval to elongated pleomorphic cells with a single prominent nucleolus and occasional mitotic figures. Both tumor components showed intense staining for vimentin, smooth muscle actin, and muscle specific actin. Herein, we report a case of a malignant glomus tumor arising in a benign glomus tumor with an immunohistochemical study and a review of literatures.
