In recent years, since the accidents during bathing had become a social problem, we analyzed the trend of them in Sapporo city and aimed to make the results well-known to citizens for prevention. Although bathing-related ambulance runs were 0 .71% of all the called emergency cases, the accidental death accounted for 7.4% of the total death toll, and was 1.5 times the traffic death. 11.7% of the bathing-related ambulance runs was the accidental death and they are estimated about 100,000 or more affairs in the whole country. The elderly aged 65 and over occupied 83.9% of the accidental death during bathing. The incidence of cardio-respiratory arrest showed a lower value of 17.6 persons per 100,000 populations than that of other cities. In the elderly, the sum of cardio-respiratory arrest and a loss-of-consciousness reached by 1.7 times of accidental death. In hot spring areas, compared with Sapporo city excluding hot spring areas, there was lesser proportion of accidental death and serious injury. The proportion in which children and adult ages get injured by fall was higher in the hot spring areas. Since it is thought that accidental death continues to increase, and the role in which bathing plays as a preventive care such as recovery from fatigue and a health promotion is large, the preventive emergency is absolutely important.

A 6-month-old baby boy had undergone the Jatene procedure at 4 days. Four months later, catheter intervention (balloon angioplasty) was performed because of severe stenosis at the bifurcation of the pulmonary arteries. Twenty days later, several episodes of cyanosis occurred and he was readmitted. The existence of shunt flow between the sinus of valsalva and the pulmonary bifurcation was detected by echocardiography and examination by 16-row MDCT revealed 2 holes at this site. Under a diagnosis of aortopulmonary (AP) window, the patient was placed on cardiopulmonary bypass and the pulmonary artery was opened after aortic clamping. There was a ridge between the bifurcation of the pulmonary arteries. After removing it, 2 holes were visualized that resembled the findings on 16-row MDCT. These holes were closed with Xenomedica patches and the main pulmonary artery was also extended with a Xenomedica patch. AP window is a rare complication after balloon angioplasty for pulmonary stenosis, but we must take great care to prevent this complication.

A 29-year-old woman, who had been diagnosed with Ebstein's anomaly associated with paroxysmal supraventricular tachycardia due to Wolff-Parkinson-White (WPW) syndrome, was referred to our hospital for treatment of congestive heart failure and tachycardia. She had undergone a catheter ablation for WPW syndrome at the age of 28 years. Subsequently, surgical treatment for Ebstein's anomaly was indicated because of persistent symptoms of heart failure due to tricuspid regurgitation (TR). The echocardiogram and pathologic findings corresponded to Ebstein's anomaly of the Carpentier type B classification, with severe displacement of the septal and posterior leaflets resulting in moderate TR. A mobile anterior leaflet of sufficient size without a cleft enabled us to successfully perform Hetzer's procedure. In this procedure, the large mobile anterior leaflet was approximated to the opposing true tricuspid annulus with a mattress suture of 3-0 polypropylene passed from the anterior leaflet annulus to the true tricuspid annulus at the site of atrialized right ventricle near the coronary sinus. The postoperative course was uneventful, and the cardiothoracic ratio reduced from 56% to 48% with mild TR. In this adult case of Carpentier's type B adult Ebstein's anomaly, Hetzer's procedure allowed reconstruction of the tricuspid valve mechanism of “leaflet-to-septum” coaptation at the level of the true annulus by approximating the anterior leaflet. This was, effective in reducing the patient's moderate TR. We conclude that this procedure is a simple and reproducible method for repairing the tricuspid valve in Ebstein's anomaly, especially for cases with a large mobile anterior leaflet.

Primary repair of the tetralogy of Fallot with absent pulmonary valve syndrome (TOF/APV) is associated with high mortality rates of 17-33%, especially in neonates. Our standard strategy involves a staged repair with a first palliation, performed during the neonatal period, that includes main pulmonary septation with an ePTFE patch, pulmonary arterioplasty for reduction of vascular dilation, and a modified Blalock-Taussig shunt. We performed successful repairs on two neonates with TOF/APV, one symptomatic and the other non-symptomatic, with this strategy. Case 1 : A 7-day-old boy had TOF/APV, with progressively worsening respiratory distress. His left bronchi, superior vena cava and left atrium were compressed by a dilated pulmonary artery, which was repaired by emergency surgery. Decreasing the diameter of the pulmonary artery (PA index from 2,550 to 525) relieved the compressed organs. Case 2 : A 16-day-old boy with TOF/APV with a main pulmonary artery that increased in diameter from 8 to 17 mm in the course of a single day. He was treated in the same fashion as Case 1. At 1 year of age, an intracardiac repair with tricuspid anuuloplasty was performed successfully. This strategy is much safer than a primary repair and is a good choice for neonatal repair of TOF/APV.

A 9-month-old boy who had been given a diagnosis of double outlet right ventricle (DORY), partial anomalous pulmonary venous return (PAPVR), ventricular septal defect (VSD), pulmonary hypertension (PH) and polysplenia with azygos connection, underwent pulmonary artery banding at the age of 6 months. At 2 months after surgery, a chest computed tomogram revealed a main pulmonary artery aneurysm and a main pulmonary artery-right pulmonary artery fistula caused by bacterial endocarditis due to a methicillin-resistant Staphylococcus epidermidis. We performed pulmonary arterioplasty and re-pulmonary artery banding for acute aggravation of cardiac insufficiency and obtained good results. This is an extremely rare case that was treated infectious pulmonary artery aneurysm and fistula after pulmonary artery banding.

We describe a case of postoperative aortic valve regurgitation (AR) after arterial awitch operation (ASO) successfully managed by the modified Konno procedure. A 4-year-old girl with complete transposition of the great arteries (TGA, Type II) had undergone the ASO (LeCompte maneuver) at 10 days of age. Because of progression of moderate AR 4 years after ASO, the modified Konno procedure with aortic valve replacement (SJM 21mm) was successfully performed. She remains in good clinical condition at the last follow-up at 5 years.

This paper presents the case of a man in his 70's with local advanced bladder cancer with hospital-developed Fournier's gangrene. The patient was hospitalized at the palliative care unit, and drainage with incision of the scrotum for symptom relief was performed to relieve severe pain. The patient experienced pain only during changing of the wound's dressing and no pain at rest after the operation. Furthermore, he reached his birthday and spent time in peace with his family. Fournier's gangrene is the necrotizing fasciitis of perineal and anal lesions, in which inflammation progresses rapidly in wide lesions, and it is associated with a high mortality rate. For Fournier's gangrene in a terminally ill patient, current agreement might depend on the patient's goal of treatment. The drainage provided for spiritual care of the patient and his family as well as pain relief. In conclusion, local drainage for Fournier's gangrene can be feasible as a choice of palliative treatment. Palliat Care Res 2011; 6(2): 340-343

Objective: Similarity of drug names is one factor of dispensing incidents.  The aim of this study was to survey the relation between sensual similarities of drug names and the occurrence of taking errors for pharmacists who actually prepare medicine.
Methods: A pair of drugs (15 incident pairs and 104 control pairs) was displayed on a computer screen at random.  The subject’s task was to determine the sensual similarity of them.  Thirteen pharmacists who prepared these pairs and caused their incidents participated in the experiment.
Results: The result showed that the sensual similarity of drug names of incident pairs was found to be highly significant in comparison to one of the control pairs [p=0.026].  However, the similarity in incident pairs is not necessarily high.  It was suggested that the similarity of drug name was not the only factor of taking error.  Multiple linear regression analyses of the sensual similarity in control pairs were performed, in which 10 variables were reported as quantitative indicators of similarity of drug name and were able to be measured on the internet.  The correlation was good [R²=0.828].  However, this regression model was not useful when adjusting to incident pairs.  In incident pairs, the similarity value calculated by the regression model was lower than the measured sensual similarity.
Conclusion: The result suggested that measured sensual similarity includes other risk factors of taking error, such as appearance similarity and/or efficacy similarity and/or short distance arrangement.  It seemed that the pharmacist’s ability complicated the factor of taking error.

Objective: Taking the wrong medicine or medication error is a serious concern to patient safety.  The aim of this study was to statistically survey the relation between the placement of drugs on medicine shelf and the occurrence of error in taking a medicine.
Methods: The study comprised 2 groups.  The incident group contained 43 cases that were erroneously taken in the Obihiro Kosei General Hospital.  The control group contained 43 drug pairs matched by the similarity index of the drug names from among the drugs used in the hospital at random.  The similarity index of drug names was based on 10 quantitative indicators.  The distance of medicine shelf arrangement was represented by three variables: the horizontal distance, the vertical distance and the distance of shelf block.  Conditional logistic regression analyses of the occurrence of medication errors were performed by evaluating the three variables of the distance factor and their interaction for error in taking a similar-sounding named drugs.
Results: Conditional logistic regression analysis revealed that the vertical distance (OR: 0.64, 95%CI: 0.42-0.99) and the distance of the shelf block (OR: 0.74, 95%CI: 0.57-0.97) were significant risk-reduction factors of medication errors.  Four variables were extracted as the most suitable logistic regression model in terms of the interaction between them.  As the interaction between 3 variables (the horizontal distance, the vertical distance and the distance of shelf block) was significant (OR: 0.93, 95%CI: 0.86-0.99), they may be considered as synergistic risk-reduction factors.  Moreover, the horizontal distance was found to be a risk-enhancement factor (OR: 1.52, 95%CI: 0.93-2.48).
Discussion: In order to reduce the risk of medication errors due to similar-sounding drug names, placement of drug on the medicine shelf should take into consideration the three coordinates of the distance factor.

(Objective) Neoadjuvant hormonal therapy (NHT) before radical prostatectomy promotes the downstaging of primary lesions. A retrospective analysis was conducted of the relationship between NHT durations and positive surgical margin rates, as well as between positive surgical margin rates and three types of prostatectomy (antegrade radical prostatectomy, retrograde radical prostatectomy, and laparoscopic radical prostatectomy (LRP)).;(Materials and Methods) This study was a retrospective analysis of 257 patients treated with radical prostatectomy during the three years between April 2002 and March 2005. Of the 257 patients, 190 were treated by NHT. NHT durations were classified into “not conducted,” “<1 month,” “1-3 month,” “3-6 month” and “>6 month,” and the relationship between positive surgical margin rates and NHT durations was investigated. Seventy-four patients underwent antegrade radical prostatectomy, 131 were treated with retrograde radical prostatectomy, and 52 underwent LRP. Positive surgical margin rates were investigated according to the types of prostatectomy, as well as according to prostate-specific antigen (PSA) levels upon diagnosis.;(Results) Positive surgical margin rates were 53.8% in the “not conducted” and “<1 month” groups, 38.8% in the “1-3 month” group, 32.4% in the “3-6 month” group, and 10.7% in the >6 month” group. Positive surgical margin rates after open surgery (antegrade and retrograde) tended to decrease when NHT durations were longer, while those after LRP tended to increase inversely. No correlation was observed between PSA levels upon diagnosis and positive surgical margin rates or between presurgical PSA levels and NHT durations.;(Conclusion) Positive surgical margin rates were not significantly different when patients were treated with NHT for 1-3 months, but they tended to decrease when NHT was for >6 months. However, positive surgical margin rates after LRP increased when NHT continued for longer periods of time. This may the result of fibrous adhesion in the vicinity of the prostate due to long-term NHT which made the surgical margins unclear.
