Purpose: This study aimed to analyze interventions for bereaved families and evaluate their effectiveness, with the ultimate goal of supporting evidence-based nursing for bereaved families. Methods: Research trends were identified based on a search of domestic databases from January 2000 to December 2022, and a meta-analysis was conducted on interventions for bereaved families. Forty-five papers were selected, and information was extracted on participants, research design, and interventions. A meta-analysis of seven papers was performed, and the effect size was calculated. Results: Fourteen papers dealt with interventions for middle-aged women who had lost their spouses, 20 used qualitative research methods, and 20 were on art therapy programs. Thirty studies had fewer than 10 participants, and most interventions had 60~120 minutes per session and 9~16 sessions in total.There were seven randomized controlled trials, and all studies included in the quality evaluation showed a low risk of bias. Four papers measured grief as an outcome, and the effect size was -1.9577 (95% CI: -2.9206 to -0.9947), indicating that the treatment significantlydecreased grief (P＜0.001). Six papers measured depression as an outcome, and the effectsize was -1.6775 (95% CI: -2.1835 to -1.1716), showing that the treatment significantly decreased depression (P＜0.001). Conclusion Intervention programs for bereaved families were shown to be effective in relieving grief and depression. However, programs should be developed that target middle-aged men who have lost their spouses and children who have lost their parents. Randomized controlled trials should also be conducted on interventions to reduce grief and depression.

Upper gastrointestinal tract angiodysplasia is rare, but it is an important cause of upper gastrointestinal bleeding. We experienced a case of hemorrhagic angiodysplasia of duodenal bulb in a patient under chronic hemodialysis due to chronic renal failure. Repeated upper GI endoscopy revealed an angiodysplasia at the posterior wall of the duodenal bulb. It was successfully treated by bipolar electrocoagulation. We report a case of angiodysplasia in chronic renal failure patient with the review of the literatures.

A ruptured aneurysm of the pancreaticoduodenal arteries is an emergency condition, with a high mortality rate. Therefore, early diagnosis and adequate management are needed. Recently, treatment with a transcatheter arterial embolization has decreased the mortality rate. A 68-year-old man presented with persistent abdominal pain and dyspnea. Contrast abdominal computed tomography revealed a large retroperitoneal hematoma, with an actively bleeding focus. An urgent celiac and superior pancreaticoduodenal arteriogram showed a contrast extravasation, about 15 X 8 mm in size, with a saccular aneurysm of the distal anterior superior pancreaticoduodenal artery; therefore transcatheter arterial embolization was performed. The patient's condition improved without complication after the embolization.

PURPOSE: Suppression of the relatively high signal intensity of fat leads to more efficient use of thedynamic range for display of tissue contrast. In order to evaluate meniscal tears, we compared a fat-suppressedturbo spin-echo(FSTSE) sequence with turbo SE(TSE). MATERIALS AND METHODS: One hundred and seven knees in 103consecutive patients referred for MR study of the knee were imaged using both FSTSE and TSE sequence. The turbo SEsequence provided proton density-weighted and T2-weighted images (dual echo technique) with an effectiveecho-train length of five. For fat-suppression, a frequency-selective chemical presaturation pulse was applied.Forty-two knees (84 menisci) were studied arthroscopically and the findings were taken as the reference standard.FSTSE and TSE images were reviewed retrospectively by two radiologists. Next, for each patient, the quality ofFSTSE and TSE images was compared;the former were scored by each reviewer as either superior to, equal to, orinferior to TSE images. RESULTS: Among the 214 menisci evaluated, the results of FSTSE and TSE imaging were verysimilar (kappa index 0.87). Twenty four tears were found during arthroscopy in 84 menisci. FSTSE imaging was moresensitive than TSE (96% versus 83%), though specificity was equal(98%). Among the 107 cases, FSTSE images wererated by both observers as superior to TSE images for overall quality and visualization of the meniscus itself.CONCLUSION: For the evaluation of meniscal tears, FSTSE sequences were more sensitive than those obtained withTSE, and their image quality was superior. For the study of meniscus tears among a large population, FSTSE istherefore more useful than TSE.

In an effort to facilitate fabrication procedure of all ceramic crowns, a novel preparation method for all ceramic crown using alumina tape was developed. The alumina tape having a uniform thickness was cast by using Doctor blade method. The physical properties of newly introduced alumina tape has biaxial flexure strength of 500.600 MPa. The value of toughness is 3.18~3,28 MPa.m(1/2) which corelates with facture and the linear shrinkage rate of the alumina tape is 0.44% during core production. The marginal fitness of the alumina tape all-ceramic restoration with 90degrees shoulder margin had average marginal discrepancy at 78.3micrometer and average marginal gap at 44.4micrometer. At the marginal preparation of 135degrees deep chamfer, the average marginal discrepancy at 82.1micrometer and the average marginal gap at 40.2micrometer had been reported. This fabrication procedure of all ceramic crowns with alumina tapes is easier and less technical sensitive for dental technicians. After restoration with new all ceramic crowns we followed the patients 2 years later, there were no complications as porcelain fractures or periodontal disease. We had good esthetic clinical results with new all ceramic crowns.

The diagnosis of neurocysticercosis is relatively easy with brain computed tomo-grarhy(CT) and/or magnetic resonance imaging(MRI) and ELISA test of serum and cerebrospinal fluid(CSF). The clinical manifestation of the disease are varied and correlated with the infection sites. The use of praziquantel and/or surgical excision are effective in treatment of the disease. The effect of treatment has been evaluated with imaging studies and changes of clinical manifestation. The authors reviewed 97 neurocysticercosis patients to evaluate the prognostic predictability of serum and CSF ELISA titers after treatment . We classified the patients into two groups. Rebound group was patients which showed higher ELISA titers after praziquantel medication than pretreatment. The responses to treatment were evaluated with the changes on brain CT or MRI. The Initial ELISA titers were lower in rebound group than those of nonrebound group, but three month after treatment, rebound group showed higher titers. The changes of ELISA titers in rebound group were greater in CSF than those in serum. The reduction of cyst on brain CT or MRI was more remarkable in rebound group than in nonrebound group and the prognosis of rebound group was better. Changes of ELISA titers was valuable in predicting the effect of treatment and prognosis.

PURPOSE: To localize and compare the neural basis of verbal and visual human working memory, we erforrned functional activation study using H2O PET. MATERIALS AND METHODS: Repeated H213O PET scans with one control and three different activation tasks were performed on six right-handed narmal volunteers. Each activation task was composed of 13 matching trials. On each trial, four targets, a fixation dot and a probe were presented sequentially and subjects task was to press a response button to indicate whether or nat the probe was one of the previous targets. Short meaningful Korean words, simple drawings and monochromic pictures of human faces were used as matching objects for verbal or visual memory. All the images were spatially normalized and the differences between control and activation states were statistically analyzed using SPM96. RESULTS: Statistical analysis of verbal memory activation with short words showed activation in the left Broca's area, premotor cortex, cerebellum and right cingulate gyrus. In verbal memory with simple drawings, activation was shown in the larger regions including where activated with short words and left superior temporal cortex, basal ganglia, thalamus, prefrontal cortex, anterior portion of right superior temporal gyrus and right infero-lateral frontal cortex. On the other hand, the visual memory task activated predominantly right-sided structures, especially inferior frontal cortex, supplementary motor cortex and superior parietal cortex. CONCLUSION: The results are :consistent with the hypothesis of the laterality and dissociation of the verbal and visual workmg memory from the invasive electrophysiological studies and emphasize the pivotal role of frontal cortex and cingulate gyrus in working memory system.

PURPOSE: To assess the changes in mean corneal refractive power (DeltaK) following pterygium surgery and to predict DeltaK in cases of combined cataract and pterygium surgery. METHODS: Thirty-seven eyes of unilateral pterygium patients who underwent pterygium surgery were analyzed retrospectively with at least more than 1 month of follow-up. Preoperative and postoperative 1 month corneal refractive power was measured using auto-keratometer (RK-F1, Canon, Tokyo, Japan). Pterygium horizontal extension, width, and area were measured and correlation with DeltaK before and after surgery analyzed. We also compared DeltaK of the contralateral normal eye. RESULTS: The mean corneal refractive (Km) power measured before and 1 month after surgery was 43.30 +/- 1.66 D and 44.07 +/- 1.42 D, respectively. The Km significantly increased at 4 weeks after surgery (p < 0.001). However, postoperative Km was not significantly different when compared with the contralateral normal eye (43.86 +/- 1.34 D; p = 0.59). All parameters of pterygium size including horizontal extension, width, and area were positively correlated with the mean DeltaK. Among parameters, horizontal extension was best correlated with mean DeltaK (p < 0.001). The mean DeltaK with horizontal extension was predicted using linear regression (2.5 mm to 1 D, 4.0 mm to 1.8 D). CONCLUSIONS: We recommend contralateral corneal refractive power or prediction of corneal refractive power using linear regression with pterygium horizontal extension for determining intraocular lens power in cases of combined cataract and pterygium surgery.
