The AMBU bag is a useful equipment at the cardiopulmonary resuscitation (CPR) or the respiratory therapy. The AMBU bag eonsists simply of a self-reflating bag, a patient valve and a inlet valve. The patient valve is a non-rebreathing valve and the self-inflating bag is a recoiled rubber bag. The inlet valve on the posterior site of self-inflstion bag is closed during the bag is squeezed, and opened during the bag is released. During reflation of bag, fresh room air through the one-way valve and fresh oxygen through the orifice for oxygen supply will mix. Therefore the inspiratory oxygen concentration is decided by a speed of re- flation of the self-reflating bag. We measured inspiratory oxygen concentration during AMBU bag ventilation under different inspiration : expiration (I:E) ratio, frequency of venti- lation, ventilatory volume and flow rate of oxygen. The results were that factors increase a inspirstory oxygen concentration are 1) decrease of I:E ratio, 2) decrease of frequency of ventilation, 3) decrease of ventilatory volume, 4) inerease of flow rate. We found that haste of physician makes frequent squeezing of AMBU bag and the haste results a decrease of inspiratory oxygen concentration.

Irreparable obstructive azoospermic patients can be treated successfully with microsurgical epididymal sperm aspiration(MESA) o. testicular sperm extraction (TESE) by intracytoplasmic sperm injection(ICSI). Obstructive azoospermic patients generally have normal spermatogenesis. The aim of this study was to see if any spermatozoa could be retrieved from non-obstructive azoospermia and to assess the efficacy of ICSI with TESE in germinal failure. 42 non-obstructive azoospermic patients revealed no spermatozoa at all in their ejaculates, even after centrifuge. The histology of 42 patients revealed 15 Sertoli cell only Syndrome, 4 maturation arrest and 23 severe hypospermatogenesis. All patients underwent extensive multiple testicular biopsy for sperm retrieval. These patients were scheduled for ICSI using testicular spermatozoa. In 25 out of 42 non-obstructive azoospermic patients, spermatozoa were recovered from multiple testicular biopsy specimen and 11 ongoing pregnancies were achieved. There are usually some tiny foci of spermatogenesis which allow TESE with ICSI in non-obstructive azoospermia. Also these patients may have sufficient sperm in the testes for ICSI, despite extremely high FSH level and small testes.

PURPOSE: Thanks to advancements in surgical techniques and instruments, many surgical modalities have been developed to replace transurethral resection of the prostate (TURP). However, TURP remains the gold standard for the surgical treatment of benign prostatic hyperplasia (BPH). We conducted a meta-analysis on the efficacy and safety of minimally invasive surgical therapies for BPH compared with TURP. METHODS: This meta-analysis used a Medline search assessing the period from 1997 to 2011. A total of 784 randomized controlled trials were identified in an electronic search. Among the 784 articles, 36 randomized controlled trials that provided the highest level of evidence (level 1b) were included in the meta-analysis. We also conducted a quality analysis of selected articles. RESULTS: Only 2 articles (5.56%) were assessed as having a low risk of bias by use of the Cochrane collaboration risk of bias tool. On the other hand, by use of the Jadad scale, there were 26 high-quality articles (72.22%). Furthermore, 28 articles (77.78%) were assessed as high-quality articles by use of the van Tulder scale. Holmium laser enucleation of the prostate (HoLEP) showed the highest reduction of the International Prostate Symptom Score compared with TURP (P<0.0001). Bipolar TURP, bipolar transurethral vaporization of the prostate, HoLEP, and open prostatectomy showed superior outcome in postvoid residual urine volume and maximum flow rate. The intraoperative complications of the minimally invasive surgeries had no statistically significant inferior outcomes compared with TURP. Also, there were no statistically significant differences in any of the modalities compared with TURP. CONCLUSIONS: The selection of an appropriate surgical modality for BPH should be assessed by fully understanding each patient's clinical conditions.

This study was carried to determine the possibility of finding motile spermatozoa and fertilization, pregnancy rate after testicular sperm extraction(TESE) with ICSI in obstructive and non-obstructive azoospermic patients. In 154 cases(132 patients), obstructive azoospermia was 77 cases and non-obstructive azoospermia was 77 cases. In obstructive azoospermia, patients generally showed normal spermatogenesis and included vas agenesis(n=8), multiple vas obstruction(n=7), epididymal obstruction (n=54). Total of 982 retrieved oocytes were obtained and 84.4% were injected. The fertilization rates with 2 PN and cleavage rate were 72.5% and 62.3%, .respectively. 30 pregnancies(38.9%) were achieved and the ongoing pregnancies were 22 cases (28.6%). In non-obstructive azoospermia, patients showed hypospermatogenesis(n=49), maturation arrest(n=4), Sertoli cell only syndrome (n=24). The various stages of spermatogenic cell could be retrieved by TESE and could be reached normal fertilization and embryo development with ICSI. Total of 1072 retrieved oocytes obtained and 80.2% were injected. The fertilization rates with 2 PN and cleavage rate were 52.8% and 68.9%, respectively. 22 pregnancies(30.1%) were achieved and the ongoing pregnancies were 19 cases(26.0%). Conclusively, the combination of TESE with ICSI using testicular spermatozoa can achieve normal fertilization and pregnancy rate and effective method in obstructive and non-obstructive azoospermic patients.

Acute malperfusion syndrome is a serious complication of acute aortic dissection. A 76-year-old female patient was admitted with acute type B aortic dissection and developed renal malperfusion during medical therapy. We are reporting a clinically successful result from the thoracic endovascular aortic repair used for malperfusion syndrome that occurred by acute type B aortic dissection.

This study was designed to analyze the prevalence rates of laboratory animal allergy (LAA) in laboratory workers who perform researches with animals, and detect the mouse urinary allergen (Mus m 1) level in animal facilities for the purpose of establishing program for prevention of exposure to allergen. Study subjects were 240 employees who were working for two animal research institutions in Korea. Then the questionnaire and skin prick tests (SPTs) using twenty allergens were conducted with them. Presence of Mus m 1 in each air borne sample collected from animal facility was determined by using enzyme-linked immunosorbent assay. Through 240 questionnaire sheets, we found that; (1) 17.0% of workers in the direct exposure group answered that they had allergic symptoms due to laboratory animals; and (2) 6.2% of them had asthmatic symptoms. Twenty one subjects (27.6%) among the subjects with common allergens positive result and five subjects (6.6%) among the subjects with negative result showed a positive response to LAA under the SPTs. The Mus m 1 concentration (1.339 ng/m3) in the sample collected during cage exchange in mouse breeding room was up to 2.8 times higher than its concentration (0.483 ng/m3) in the sample collected at the stationary state. We suggest that LAA management programs including control of exposure to laboratory animal allergens should be considered as a measure to reduce the incidence of LAA and relieve the laboratory worker's allergic sensitivity to laboratory animals.

Diffuse mesotheliomas of the pleura and peritoneum are considered "signal tumors" of asbestos exposure. Although asbestos use in Korea started before the national liberation, it rose abruptly with economic development in 1970's. Considering latent period of mesotheliomas as twenty years, occupational mesothelioma cases would increase rapidly. In Korea construction is a major industry which use asbestos. Because workers in construction industry are mostly composed of daily based workers, it is hard to calculate the number of workers involving asbestos related work, to manage them with organized method, to educate them about adverse effects of asbestos and protection methods, to check health status of them periodically, and to follow them up. Although a case of occupational mesothelioma which was found in a asbestos textile worker have been reported, no case related with construction workers have been reported so far in Korea. The authors experienced occupational malignant pleural mesothelioma combined with asbestosis in a boilermaker and plumber in a construction industry.
