RESUMEN

Background@#The prone position is used for a variety of procedures and surgeries, and hypotension is a commonly encountered complication. Case : A 75-year-old obese woman with lumbar spinal stenosis underwent posterior lumbar spinal fusion and posterolateral interbody fusion under general anesthesia. Before the surgery, when she was positioned on a Jackson spinal table in the prone position, sudden severe hypotension and hemodynamic collapse developed. The circulatory collapse was refractory to intravascular volume expansion and administration of inotropes and vasopressors. However, the application of external abdominal support immediately restored hemodynamic stability. The patient successfully underwent the surgery using an external abdominal support, and no post-operative complication was noted, including abdominal compartment syndrome. @*Conclusions@#The Jackson spinal table allowed the abdomen to hang freely, providing abdominal decompression while resulting in a severely sagged abdomen. We suspected that the sagging abdomen had pulled the abdominal contents downwards, kinking the inferior vena cava or causing a venous pool in the abdomen, resulting in the obstruction of venous return to the heart.

RESUMEN

Objective of this study was to compare the color stability, mechanical and chemical properties of three different types of temporary crown resins. Commercially available powder-liquid (Group PL), light-cured (Group LC) and auto-mix syringe (Group AM) types' temporary crown resins were used as experimental groups for each of the evaluation. All the test groups were evaluated after 1 day and 7 days of immersion in various staining solutions. The colors of all groups before and after storage in the staining solutions were measured by a spectrophotometer based on CIE Lab system, and the color differences (ΔE(*)) thereby calculated. Micro hardness test was performed before water storage and aging after 7 days at 37 ℃. In addition, flexural strength, water sorption and solubility tests were performed according to international standard, ISO 10477. All experimental groups showed significant color change in staining solutions when compared to those stored in the control solution (distilled water) (p PL > LC (p<0.05). Water sorption and solubility increased in the following order: AM < PL < LC (p<0.05). The results of this study would provide useful information when choosing temporary crown resin types in various clinical situations.

RESUMEN

Uterine adenosarcoma (AS) are rare tumors and have more favorable outcomes than the aggressive uterine carcinosarcomas. Uterine adenosarcoma with sarcomatous overgrowth (ASSO) is a variant form of AS and exhibits aggressive growth of tumor and the prognosis is relatively poor compared with typical AS. Usually patterns of metastasis have been known to behave like endometrial carcinoma and spread through the lymphatics. Brain metastasis from uterine AS is extremely rare. Herein, we report a case of successfully surgically removed solitary brain metastasis without any extracranial recurrence from uterine ASSO after 4 years of primary treatment.

RESUMEN

PURPOSE: The prognosis of gastric cancer patients with bone marrow metastases is extremely poor. The current study was conducted to evaluate the clinical outcomes of advanced gastric cancer patients with bone marrow metastases. MATERIALS AND METHODS: We retrospectively reviewed the medical records of 26 advanced gastric cancer patients with bone marrow metastases who were treated at Soonchunhyang University Hospital between September 1986 and February 2009. RESULTS: The median age was 46 years (range, 24 to 61 years). All patients had poorly differentiated adenocarcinoma, including 17 signet ring cell carcinomas. The majority of the patients had thrombocytopenia, anemia, and elevated lactate dehydrogenase levels. Sixteen patients (61.5%) received palliative chemotherapy (median, 4 cycles; range, 1 to 13 cycles). The median overall survival after detection of bone marrow metastases for the cohort of patients was 37 days (95% confidence interval, 12.5 to 61.5 days). The median overall survival after detection of bone marrow involvement was 11 days in the best supportive care group (range, 2 to 34 days) and 121 days (range, 3 to 383 days) in the palliative chemotherapy group (p<0.001). The causes of death were tumor progression (11 patients, 45%), brain hemorrhage (6 patients, 25%), infection (5 patients, 21%), and disseminated intravascular coagulation (1 patient, 4%). There were no chemotherapy-related deaths. CONCLUSION: Palliative chemotherapy could be considered in advanced gastric cancer patients with bone marrow metastases as a treatment option.

RESUMEN

BACKGROUND: Currently, the incidence of hepatitis A is on the increase in Korea. Although there is emphasis on contact precautions, the nosocomial outbreak of hepatitis A virus (HAV) in healthcare personnel has increased within endemic areas because these workers inevitably come in close contact with patients and work under suboptimal hygiene conditions. In this study, we evaluated the necessity of immunization against HAV for healthcare personnel. METHODS: We investigated the seropositivity of serum immunoglobulin G (IgG) anti-HAV antibody (Ab) in 672 healthcare personnel on the basis of their age-group, sex, and occupation in Soon Chun Hyang University Hospital and Soon Chun Hyang University Bucheon Hospital. RESULTS: The subjects were divided into 6 groups on the basis of their ages to identify differences among the various age groups in the number of cases with HAV Ab seropositivity. Significant intergroup differences were noted in this respect: 21-25 years, 2/152 (1.3%); 26-30 years, 33/245 (13.5%); 31-35 years, 70/148 (47.3%); 36-40 years, 52/79 (65.8%); >40 years, 44/48 (91.7%). CONCLUSION: The number of seropositive cases was low among young healthy personnel: low seropositivity is an emerging risk for vulnerable population. With the increase in the incidence of hepatitis A, healthcare personnel have become a risk population for hepatitis A, as are community residents. Therefore, for healthcare personnel working in hospitals, immunization against HAV should be recommended for personnel younger than 30 years, and serological testing for older personnel.

RESUMEN

Post-cardiac injury syndrome (PCIS) includes post-myocardial infarction syndrome and post-pericardiotomy syndrome. PCIS is usually observed 1~6 weeks after cardiac surgery or myocardial infarction, and rarely after pacemaker implantation, coronary perforation, pulmonary thromboembolism, or radio-frequency ablation. PCIS is characterized by a low-grade fever, pleuritic chest pain, myalgia, a pericardial friction rub, increased inflammatory markers, and pericardial and pleural effusions. Although the pathophysiology of PCIS is controversial, the presence of anti-heart antibodies has implicated an autoimmune response, which has been widely accepted. The treatment of PCIS includes nonsteroidal anti-inflammatory drugs and corticosteroids. Currently, intervention is being performed increasingly in complicated obstructive coronary artery disease, such as chronic total occlusion, long-segment obstructive lesion, and left main coronary artery disease. We report a very rare case of PCIS following coronary artery perforation during PCI.
