Amniotic fluid embolism (AFE) is a rare but potentially fatal complication that occurs acutely during pregnancy or within 12 h of delivery. The management of AFE focuses initially on supportive measures for cardiopulmonary stabilization. Extracorporeal membrane oxygenation should be considered in patients who are unresponsive to medical treatment in order to prevent additional hypoxia and subsequent organ failure. We present a 41-year-old woman with clinical AFE who developed acute respiratory distress syndrome and was treated successfully with extracorporeal membrane oxygenation.

Colonization of the pre-transplant lung by multidrug-resistant bacteria affects short- and long-term outcomes of lung transplantation. However, there are no case reports on the colonization of a pre-transplant lung by drug-resistant Acinetobacter baumannii. We report a case of extensively drug resistant (XDR) A. baumannii colonization in the tracheobronchial tree that caused severe infectious complications after bilateral lung transplantation. A 23-year-old man diagnosed with bronchiolitis obliterans syndrome (BOS) 4 years earlier with a history of allogenic bone marrow transplantation for acute lymphoblastic leukemia was admitted to the hospital with dyspnea. Due to progressive hypercapnic respiratory failure, long-term mechanical ventilation was started after a tracheostomy was performed, and the patient underwent a bilateral lung transplantation to treat end-stage BOS. After the transplantation, the colonization of XDR A. baumannii caused severe bacterial pneumonia in the early postoperative period. Combined treatment with colistin and meropenem led to recovery from the pneumonia but caused drug-induced renal failure. Because many centers are willing to transplant candidates who are on mechanical ventilation or extracorporeal life support, the incidence of XDR A. baumannii colonization of pretransplant lungs is expected to increase. Further studies are needed to examine pre-transplant management strategies in patients colonized with XDR A. baumannii.

Purpose: To investigate the biometric characteristics of eyes with pseudoexfoliation syndrome (PEX) according to the anterior chamber depth (ACD) by comparing them to patients with acute angle closure (AAC) and a control group. Methods: A total of 130 eyes of 121 subjects (PEX, 49 eyes; AAC, 28 eyes; and control, 53 eyes) were included in the study. Axial length (AL), ACD, and lens thickness (LT) were measured with an IOL Master® 700 (Carl Zeiss Meditec, Jena, Germany). The total PEX (PXall) group was divided into a PEX with deep ACD group (PXd) and a shallow ACD group (PXs) based on an ACD of 2.70 mm. We compared the biometric results among the PXall, PXd, PXs, AAC, and control groups. Results: There was no significant difference in AL between the PXall and control groups; however, the PXall group had a shallower ACD and thicker lenses. After dividing the PXall group into two groups based on ACD, the PXd group showed no difference in LT compared to the control group (p = 0.113). The LT of the PXs group was thicker than those of the PXd and control groups (p < 0.001 and p < 0.001, respectively). The PXs group had longer ALs than the AAC group (p = 0.025); however, there was no difference in LT or in the ratio of LT to AL (p = 0.222 and p = 0.076, respectively). Conclusions The biometric characteristics were different in eyes with PEX based on ACD. PEX patients with deep ACDs showed no difference in biometry compared to the control group; however, PEX patients with shallow ACDs showed characteristics of a thick LT, similar to AAC patients. There was no difference in the ratio of LT to AL among groups.

A 36-year-old female patient with aplastic anemia developed massive hemoptysis and was placed on ventilator support. However, airway obstruction by blood clots triggered desaturation and ventilator malfunction. Manual ventilation was initiated to improve oxy-genation, and emergency flexible bronchoscopy was performed to clear the airway. Nevertheless, the patient developed extensive subcutaneous emphysema, pneumothorax, and pneumomediastinum.

Atypical hemolytic uremic syndrome (HUS) in adults is a life-threatening disorder characterized by acute renal failure, microangiopathic hemolytic anemia, and thrombocytopenia, which is not related to E. coli. Digital gangrene is one of the grave signs in emergency medicine because it requires prompt evaluation and treatment. We describe a 37 year-old Thailand woman, initially treated for suspected Neisseria septicemia, who went on to develop renal complications, thrombocytopenia and hemolytic anemia, which made the diagnosis of atypical hemolytic uremic syndrome. The patient was complaining of dysesthesia on all extremities and severe pain in both legs. Serologically, she was diagnosed as systemic lupus erythematosus (SLE). She was treated with plasma exchanges using fresh frozen plasma, parenteral steroid, anticoagulant and antibiotics, successfully. This is the first report of digital gangrene complicated by atypical HUS in a patient with SLE in Korea.

PURPOSE: 1) to construct cohorts according to risk scores calculated with the Gail Breast Cancer Risk Assessment Tool (Gail et al., 1989) (Gail) and the Breast Cancer Risk Appraisal (Lee et al,. 2003) (Lee) 2) to identify the distribution of risk factors and preventive behavior stages between the cohorts 3) to identify abnormal breast conditions in risk cohort. METHOD: Using convenience sampling, 775 rural women were selected. Risk appraisal was scored using Gail and Lee. Preventive behavior stages for BSE (Breast self examination) and mammography were measured using 4 stages of the Transtheoretical Model (Prochaska & DiClemente, 1983). RESULTS: 1) The risk cohort according to Gail was 12.3% (n=95), and Lee, 3.1% (n=24). 2) There were significant differences in the distribution of risk factors (age, family history, age at 1st live birth, age at menarche, number of breast biopsy, history of breast disease, and breast-feeding) between cohorts. 3) There was a significant difference in the distribution of the stage of BSE according to Lee. 4) Six women in the risk group detected masses or nodules and physician consultation and ultrasonography were recommended. CONCLUSION: On the basis of the constructed cohorts, further longitudinal studies of cohorts are recommended with interventions according to characteristics of cohorts.

Pneumatosis intestinalis (PI) is a very rare condition that is defined as the presence of gas within the subserosal or submucosal layer of the bowel. PI has been described in association with a variety of conditions including gastrointestinal tract disorders, pulmonary diseases, connective tissue disorders, organ transplantation, leukemia, and various immunodeficiency states. We report a rare case of a 74-year-old woman who complained of dyspnea during the management of acute asthma exacerbation and developed PI; but, it improved without any treatment.

BACKGROUND/AIMS: Vascular endothelial growth factor (VEGF) is an important mediator of angiogenesis. However, little is known about the potential use of serum levels of VEGF as a biomarker for asthma. We investigated the differences in VEGF levels among normal controls, stable asthma patients, and those with exacerbation of acute asthma. All subjects were young males. METHODS: We measured VEGF levels in each patient group, and examined any serial changes in those with acute exacerbation. RESULTS: VEGF levels were significantly higher in stable asthmatic patients and even more so in acute asthmatic patients, compared to healthy controls. However, there was no correlation between VEGF levels and forced expiratory volume in 1 second in patients with stable asthma. In addition, there were no correlations between VEGF levels and asthma control test scores. In patients with acute exacerbation, VEGF levels significantly increased during the acute period; their levels decreased gradually at 7 and 14 days after treatment. CONCLUSIONS: Compared to normal control patients, the serum levels of VEGF were elevated in stable asthma patients and even more elevated in patients with acute exacerbation. However, the role of VEGF as a biomarker in stable asthma is limited. In patients with acute exacerbation, VEGF levels were associated with clinical improvements.

Background/Aims: Thymic stromal lymphopoietin (TSLP) is an epithelial cell-derived cytokine that plays a key role in Th2-mediated inflammation, both directly by promoting the proliferation of naïve CD4 Th2 cells, and indirectly by activating dendritic cells (DCs). TSLP-activated DCs induce the expansion of chemoattractant receptor homologous molecule expressed on Th2 (CRTH2)+ CD4+ Th2 memory cells, which undergo a Th2 response and express prostaglandin D2 (PGD2) synthase. CRTH2, a PGD2 receptor, is a selective Th2-cell surface marker. We investigated the effects of an anti-TSLP antibody (Ab) and a CRTH2 antagonist, as well as their mechanisms of action, in a mouse model of acute asthma. Methods: BALB/c mice were sensitized and challenged with ovalbumin. We then evaluated the effects of the administration of an anti-TSLP Ab either alone or together with a CRTH2 antagonist on cell counts, Th2 cytokine levels in bronchoalveolar fluid, and the levels of epithelium-derived cytokines such as TSLP, interleukin (IL) 33, and IL-25 in lung homogenates, as well as airway hyper-responsiveness (AHR). Results: Anti-TSLP Ab and the CRTH2 antagonist significantly attenuated eosinophilic airway inflammation, AHR, and the expression of Th2 cytokines. The expression of GATA-3 and the levels of IL-33 and IL-25 in lung tissues were affected by the combined anti-TSLP and CRTH2 antagonist treatment. Conclusions These results suggest that the dual blockade of TSLP and CRTH2 may serve as an effective treatment target for eosinophilic asthma.
