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.

PURPOSE: Preoperative on-screen templating is a method of using acetate templates on digital images. The aim of the present study was to evaluate the accuracy, intra- and interobserver reliabilities of preoperative on-screen templating using digital radiographs for total hip arthroplasty (THA). MATERIALS AND METHODS: Two hundred patients with hip disease who were treated with primary cementless THA were retrospectively evaluated. The accuracy of on-screen templating was assessed by comparing the predicted prosthesis sizes with the actual sizes used operatively. The inter- and intraobserver reliabilities of the templating results were also evaluated. RESULTS: The prosthesis prediction accuracy within ±one size was 96.6% for the cup size and 97.8% for the stem size. The inter- and intraobserver reliabilities for the implant size were substantial (kappa>0.70). The intra- and interobserver reliabilities for the leg length discrepancy and femoral offset difference using the intraclass correlation coefficient ranged from 0.89 to 0.97. CONCLUSION: Preoperative on-screen templating using digital radiographs showed substantial accuracy and reliability for implant prediction. It is an effective method for predicting the size of implant, correcting the leg length discrepancy and restoring the femoral offset.

We experienced a case of Ebstein's anomaly prenatally by fetal sonography. Ebstein's anomaly is a rare congenital heart defect characterized by abnormally downward displacement of the septal and posterior leaflets of the tricuspid valve. In the absence of tricuspid regurgitation, this condition may be completely asymptomatic. On the other hand, symptomatic newborns often develop life-threatening congestive heart failure. A 30-year-old multiparous woman was referred for the evaluation of fetal cardiac defect at 26th gestational week from a private clinic. Fetal ultrasonography showed markedly enlarged right atrium and downward displacement of tricuspid valve into the right ventricle. After discussion with the patient, the pregnancy was terminated and Ebstein's anomaly was confirmed by autopsy.

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.

PURPOSE: To gain insight on transcriptional repression of Topo II a in HL-60 cells arrested to G2/M and M phase, the levels of Topo IIa mRNA and the binding activity of ATF have been investigated with Northern blot hybridization and DNA mobility shift assay, respectively. MATERIALS AND METHODS: HL-60 cells were grown in RPMI 1640 medium supplemented with 10% heat-mactivated fetal bovine serum and antibiotics in a humidified 5% CO2 at 37C degree. Total RNA was prepared by a modification of the method of Karlinsey et al. Northern blot hybridization was performed by the method of Virca et al. A Xho I-Mlu I fragment of phTOP2 was used as probe for Northern blot analysis of Topo II a mRNA. DNA mobility shift assay was performed by the method of Lim et al. End labeled DNA oligomer (upper strand, 5-TCTCCGCTATGACGCCGAGTGGTG-3) for ATF binding activity was mixed with nuclear extracts in a 20 pl reaction volume containing 60 mM KC1, 12 mM HEPES, pH 7.9, 5 mM MgCl2, 0.2 mM EDTA, 0.2 mM DTT, 12% glycerol, and 2 ug of poly [dI-dC]. RESULTS: HL-60 cells were arrested at G2/M phase and M phase after taxol or nocodazole treatment. The levels of Topo II a mRNA were reduced at 24 hours after exposure with nocodazole or taxol but the unknotting activities were not changed. DNA mobility shift assay using oligonucleotide containing the ATF binding site showed that ATF binding activity was reduced after pretreatment of nododazole or taxol. CONCLUSIONS: These results suggest that the reduction of ATF binding activity may be important to transcriptional repression of Topo II a gene by nocodazole and taxol in HL- 60 cells.
