Zolpidem is widely used for insomnia and is known to have relatively few side effects. There have been several reports of side effects, but only a few for withdrawal symptoms. A 41-year-old woman developed convulsions 4 days after discontinuing zolpidem. She was taking more than 10 times the standard dosage. After electroencephalography monitoring without antiseizure medications, she showed no more seizures. This case highlights the danger of zolpidem withdrawal and warns about the easy accessibility of zolpidem for individuals.

Many patients regard tonsillectomy as a minor operation because it is performed frequently. Although tonsillectomy is considered a relatively safe surgical procedure, numerous complications have been described. The common complications are hemorrhage, infection, and following anesthesia, aspiration, cardiac arrhythmia, and laryngeal trauma. Cervicofacial emphysema and pneumomediastinum are rarely observed sequelae of surgical intervention in the upper aerodigestive tract. Although these complications resolve spontaneously in most cases, a few cases result in tension pneumothorax and other life-threatening conditions. Symptoms include chest pain, neck pain, dyspnea and odynophagia. Treatment involves frequent assessment of the airway and extent of the emphysema. The authors of the present study report of a patient who developed pneumomediastinum shortly after an adenotonsillectomy as well as a review of the related literature.

PURPOSE: The Src homology 2 domain–containing adaptor protein B (SHB) is widely expressed in immune cells and acts as an important regulator for hematopoietic cell function. SHB silencing induces Th2 immunity in mice. SHB is also involved in T-cell homeostasis in vivo. However, SHB has not yet been studied and addressed in association with dendritic cells (DCs). MATERIALS AND METHODS: The effects of SHB expression on the immunogenicity of DCs were assessed by Shb gene silencing in mouse bone marrow–derived DCs (BMDCs). After silencing, surface phenotype, cytokine expression profile, and T-cell stimulation capacity of BMDCs were examined. We investigated the signaling pathways involved in SHB expression during BMDC development. We also examined the immunogenicity of SHB-knockdown (SHB(KD)) BMDCs in a mouse atopic dermatitis model. RESULTS: SHB was steadily expressed in mouse splenic DCs and in in vitro–generated BMDCs in both immature and mature stages. SHB expression was contingent on activation of the mitogen- activated protein kinase/Foxa2 signaling pathway during DC development. SHB(KD) increased the expression of MHC class II and costimulatory molecules without affecting the cytokine expression of BMDCs. When co-cultured with T cells, SHB(KD) in BMDCs significantly induced CD4+ T-cell proliferation and the expression of Th2 cytokines, while the regulatory T cell (Treg) population was downregulated. In mouse atopic dermatitis model, mice inoculated with SHB(KD) DCs developed more severe symptoms of atopic dermatitis compared with mice injected with control DCs. CONCLUSION: SHB expression in DCs plays an important role in T-cell homeostasis in vivo by regulating DC-mediated Th2 polarization.

BACKGROUND: Coronary arterioveonus fistula(CAVf) is a rare congerital coronary artery anomaly in adults. CAVF is related with some clinincal significances, such as angina, congestive heart failure and bacterial endocarditis. METHOD: We analyzed clincial characteristics in 10 patients(mean age=52.1 +/- 12.5 year) of adult CAVF, who were diagnosed as CAVF by coronary angiogram from Jan. 1993 to Mar. 1997 in Chonnam University Hosptial. RESULTS: Five out of 10 patients complained of chest pain, four had dyspnea and one had hemoptysis. In seven patients, arteries of CAVF were originated from left coronary arteries, from right coronary artery in one, and from both coronary arteries in two. CAVF was drained into pulmonary artery in six patients, right ventricle in two, right atrium in one, and left ventricle in one. CONCLUSION: Chest pain and dyspnea are common in symptomatic patients with CAVF are originated most commonly from left coronary arteries and drained into pulomonary arteries in Korean adults.

OBJECTIVE: This study was performed to evaluate the influence of maternal age on embryo quality and the frequency of multiple pregnancy in IVF-ET program. METHOD: 86 conventional IVF-ET cycles were divided into three groups according to the age by 5 year (group A: 26-30, group B: 3135, group C: 36-40 yrs). The in vitro fertilization and development outcome (fertilization, cleavage and high quality embryo rate) and the pregnancy outcome (pregnancy, implantation, G-sac/high quality embryo and multiple pregnancy rate) were examined. And then, these results were compared among the groups. RESULTS: The rates of fertilization (62.7, 68.5 and 65.4%, respectively) and cleavage (95.6, 97.6 and 98.0%, respectively) were not different among the groups. And the high quality embryo (HQE) rate also was not different among the groups (61.8, 62.9 and 62.8%, respectively). The pregnancy rate of group C (23.3%) was significantly lower than that of group A (41.2%) and B (48.7%). And the implantation rate was significantly decreased to group B (32.2%) and C (14.3%) when compared to group A (71.4%) and B (36.8%). CONCLUSION: The pregnancy rate was significantly decreased over 35 years. The G-sac/HQE and multiple pregnancy rate were significantly high below 31 years. Thus, these results suggest that the number of high quality embryo transferred should be limited by the age and another criteria for embryo quality evaluation were required for single embryo transfer.

BACKGROUND: Indications and applications of percutaneous transluminal coronary angioplasty(PTCA) has been broaden in reccent years. However,we considered many aspects in performing angioplasty in patient with multivessel disease. There were procedural success rate, complication, risk, restenosis and long-term effect. So we evaluated the initial success rate, safety and follow-up results. METHODS: To assess the likelihood of initial success in patients with multivessel coronary artery disease, single or multiple site angioplasy were performed at 449 lesions from 273 patients(Male 202,Female 71, Mean age 60.0+/-9.4 years). To evaluate the restenosis rate of angioplasty in multivessel disease, follow-up coronary angiogram were performed at 164 lesions from 95 patients at average 6months after angioplasty. RESULTS: The extent of coronary artery disease revealed that two vessel disease were 200(73.3%) and triple vessel disease were 73(26.7%). Single vessel angioplasty(SVA) was performed in 180(40.1%) lesions and multivessel angioplasty(MVA) was performed in 269(59.9%) lesions. Procedural success was achieved 377(84.0%) out of total 449 lesions. The proccdural success rate was 81.1% in SVA and 85.9% in MVA. According to major epicardial coronary artery, procedural success rate of left anterior descending artery was 82.0%, left circumflex artery 92.4% and right coronary artery 79.4%. According to angiographic morphology of lesions, procedural success rate of type A was 95.7%, type B 88.9% and type C 56.4%. Complete revascularization was done in 87 patients(31.9%) out of 273 patients. Major cause of failure of angioplasty in multivessel disease was inability to pass the guide wire cross the lesion due to total occlusion. Complications included dissection in 101, acute closure in 7(9.7%), coronary artery perforation in 2, cardiogenic shock in 1 and ventricular fibrillation in 1. Follow-up coronary angiography revealed the restenosis rate was 42.2%. CONCLUSION: Coronary angioplasty in selected patients with multivessel coronary artery disease might be useful and have relatively good immediate and long-term results.
