STUDY DESIGN: Thirteen patients with cervical interlocked facets dislocation in whom closed reduction by skull traction was failed were evaluated about the patterns of ruptured disc fragment. Objects : To evaluate the causes of failure at closed reduction, and the relation between ruptured discs and interlocked facets, and the treatment results through an anterior approach. SUMMARY OF LITERATURE REVIEW: In traumatic dislocation of the cervical facet joints, spinal cord or nerve roots injury associated with the ruptured disc fragment has been reported. However, there is few report evaluating the patterns of ruptured disc fragment as a cause of reduction failure. MATERIALS AND METHODS: Between 1988 and 1997, thirteen patients were treated by anterior fusion with plate after complete removal of the intervertebral disc through anterior approach and reduction of interlocked facets by O1iveira method. They have been followed for an average of 36 months(range : 12-96 months). The interlocking was bilateral in seven cases and unilateral in six cases. We assessed the types of ruptured disc fragment by preoperative MRI and CT and the clinical and radiological results. RESULTS: Ruptured disc fragment was found in all thirteen patients with interlocked facets dislocation. The patterns of ruptured discs were within the uncovertebral joints in 5 cases, posterioly under the posterior longitudinal ligament in 3 cases, anteriorly under intact anterior longitudinal ligament in 3 cases and combined under the anterior and posterior longitudinal ligament in 2 cases. The displacement of ruptured disc fragment were seemed to be the cause of failure in closed reduction. CONCLUSIONS: Intervertebral disc injury should be evaluated carefully with MRI and CT in the lower cervical interlocked facet dislocations before trial of reduction or decision makings of treatment.

OBJECTIVES: Numerous studies have revealed the adverse health effects of acute and chronic exposure to particulate matter less than 10 mum in aerodynamic diameter (PM10). The aim of the present study was to examine the spatial distribution of PM10 concentrations and cardiovascular mortality and to investigate the spatial correlation between PM10 and cardiovascular mortality using spatial scan statistic (SaTScan) and a regression model. METHODS: From 2008 to 2010, the spatial distribution of PM10 in the Seoul metropolitan area was examined via kriging. In addition, a group of cardiovascular mortality cases was analyzed using SaTScan-based cluster exploration. Geographically weighted regression (GWR) was applied to investigate the correlation between PM10 concentrations and cardiovascular mortality. RESULTS: An examination of the regional distribution of the cardiovascular mortality was higher in provincial districts (gu) belonging to Incheon and the northern part of Gyeonggido than in other regions. In a comparison of PM10 concentrations and mortality cluster (MC) regions, all those belonging to MC 1 and MC 2 were found to belong to particulate matter (PM) 1 and PM 2 with high concentrations of air pollutants. In addition, the GWR showed that PM10 has a statistically significant relation to cardiovascular mortality. CONCLUSIONS: To investigate the relation between air pollution and health impact, spatial analyses can be utilized based on kriging, cluster exploration, and GWR for a more systematic and quantitative analysis. It has been proven that cardiovascular mortality is spatially related to the concentration of PM10.

BACKGROUND: To clarify the clinical significance of CEA and CA19-9 in patients with gastric cancer, we evaluated the correlation between tissue expression, the peripheral and the portal levels of these tumor markers, and ten clinicopathological factors, as well as the prognosis. METHODS: Surgical specimens from 40 patients with gastric cancer were examined by using immunohistochemical staining with anti-CEA and anti-CA19-9 monoclonal antibodies. Serum levels of CEA and CA19-9 in the portal and the peripheral blood were measured by using immunoradiometric assays. RESULTS: Positive values of the portal venous CEA were more common in patients with lymph-node metastasis, distant metastasis, and lymphatic invasion than in those without these factors. Curative surgery was performed in 50.5% of the patients with high portal CEA levels and in 90.6% of the patients with low portal CEA levels. Positive values of the peripheral venous CEA were significantly higher in cases with lymph-node metastasis. The positive rate of CA19-9 immunohistochemistry was significantly higher in patients with distant metastasis and in non-curative surgery. The positive rate of peripheral venous CA19-9 was higher in cases with distant metastasis. The three-year survival rate of patients with negative tissue CEA was significantly higher than that of patients with a positive result. The peripheral venous levels of CEA and CA19-9 reflected the portal venous levels accurately. CONCLUSIONS: These results suggest that immunohistochemical examination of CEA in patients with gastric cancer is useful for the evaluation of the biological aggressiveness and progression of the disease and can be used for making a prognosis.

PURPOSE: We designed this study to identify and suggest the reasonable timing of adjuvant radiotherapy in the treatment of uterine carcinosarcoma according to the surgical intent and patterns of progression. MATERIALS AND METHODS: We retrospectively analyzed a total of 50 carcinosarcoma patients diagnosed between 1995 and 2010. Among these 50 patients, 32 underwent curative surgery and 13 underwent maximal tumor debulking surgery. The remaining five patients underwent biopsy only. Twenty-six patients received chemotherapy, and 15 patients received adjuvant radiotherapy. RESULTS: The median follow-up period was 17.3 months. Curative resection (p < 0.001) and stage (p < 0.001) were statistically significant factors affecting survival. During follow-up, 30 patients showed progression. Among these, eight patients (16.0%) had loco-regional progression only. The patients who had received adjuvant radiotherapy did not show loco-regional progression, and radiotherapy was a significant negative risk factor for loco-regional progression (p = 0.01). The time to loco-regional progression was much earlier for non-curative than curative resection (range, 0.7 to 7.6 months vs. 7.5 to 39.0 months). CONCLUSION: Adjuvant radiotherapy in the treatment of carcinosarcoma might be related to a low loco-regional progression rate. Radiotherapy should be considered in non-curatively resected patients as soon as possible.

Purpose: Cancer survivors and family caregivers may experience a vague sense of fear or worry about the possibility of recurrence.The family caregivers of cancer survivors experience numerous psychological hardships because, depending on the patient’s state, they must play various roles and accompany the patient through a series of events. Accordingly, this study aimed to investigate the nature and structure of the experiences of family caregivers of cancer survivors in relation to the fear of cancer recurrence. Additionally, it sought to obtain the central meanings associated with these experiences. Methods: We recruited four adult family caregivers of patients who were diagnosed with cancer between February and October 2020. The caregiver participants voluntarily agreed to participate in the study. To analyze their experiences regarding fear of cancer recurrence, we collected data using the qualitative case study and by conducting individual in-depth interviews. Results: Family caregivers’ experiences comprised four themes (“Standing at the edge of a cliff,” “Ambushed by worries,” “Anxiety I never want to experience again,” and “Making efforts to relieve anxiety”) and 11 subthemes. Conclusion Family caregivers of cancer survivors experience daily psychological hardships owing to fear of cancer recurrence. It is important to identify the unmet needs of family caregivers and provide practical and professional nursing interventions.
