BACKGROUND: The number of patients of doxylamine overdose has increased, but there were little clinical reports. The purpose of this study is review the patients of doxylamine overdose for aid clinical decision making of patients disposition. METHODS: We reviewed medical records of patients who ingested doxylamine succinate retrospectively from Jan. 1, 1996 to Dec. 31. 1996. Data that was recorded were followed: age, sex, psychiatric history, amounts of ingestion, time interval from ingestion to arrival to hospital, initial vital signs and symptoms, EKG, chest PA, Lab. findings, treatment, patients disposition, length of hospital stay, complication. RESULTS : 1) Total number of patients was ninety and average dosage of ingestion was 1062mg. 2) Tachycardia was the most frequent anticholinergic symptom(46%). 3) Routine lab. findings was not abnormal except one patient who was diagnosed as Rhabdomyolysis. 4) Gut decontamination was performed in patients who had arrived at hospital in 2-3 hours, and who had ingested large dose of drug. 5) Five patients were admitted to Psychiatric dept. and one patient was admitted to emergency dept. for treatment of rhabdomyolysis. 6) The mean duration of hospital stay was 6.5 hours. CONCLUSION: The patients who ingested overdose of doxylamine was managed safely in emergency department, but we should warn against the possibility of rhabdomyolysis.

We report of a successfully treated case of fatal bronchospasm, which developed after N-acetylcysteine bolus intratracheal instillation in a 49-year-old female patient with bronchial asthma undergoing laparoscopic cholecystectomy. N-acetylcysteine has been widely used as a potent mucolytic agent since 1963, with few reported adverse reactions. Its mucolytic action is due to the breakage of disulfide bonds in mucus mucoproteins. Most adverse reactions to N-acetylcysteine are usually mild and respond to the termination of the medication and symptomatic treatment with antihistamine. However, several cases of fatal bronchospasm have been reported in asthmatic patients after inhaled or intravenous N-acetylcysteine. N-acetylcysteine induced bronchospasm could be avoided in most asthmatic patients if its concentration is not allowed to exceed 10%, and concomitant beta2-selective bronchodilators are utilized. Nevertheless, asthma is still a potent risk factor and requires special precautions, including careful risk-versus-benefit assessment, close observation and the immediate availability of resuscitation equipment and staff in the event of life-threatening bronchospasm.

PURPOSE: Postoperative voiding dysfunction is a bothersome complication after mid-urethral sling surgery. The current study presents multiple repeated postoperative voiding trials against a urine load of preoperative functional bladder capacity, as estimated by a preoperative frequency volume chart, to identify the relevance of preoperative and immediate factors to the outcome. METHODS: A total of 180 patients were enrolled from August 2008 to August 2011. Patients received mid-urethral sling surgery with a transobturator tape, with or without concomitant cystocele repair. Patients reported relevant medical histories and a 3-day frequency volume chart and underwent urodynamic studies. After surgery, patients were filled to their maximum bladder capacity as dictated by their frequency volume chart and performed the first voiding trial. Two subsequent voiding trials were performed after natural filling. Failure of any single voiding trial was considered failure. Patients who failed the final voiding trial received intermittent catheterization to follow-up. After screening for relevant factors with the use of univariate analyses, preoperative, surgical, and postoperative factors predicting outcome were estimated by logistic regression analysis. RESULTS: The urine load at the voiding trial and the peak flow rate immediately preceding the voiding trial predicted voiding trial success in the multivariate analysis. Urine load and previous trial peak flow rate were relevant when tested against each individual voiding trial. Preoperative and surgical factors, such as age, parity, and concomitant cystocele repair, showed significance in the univariate analysis. Overall, 16.1% of patients who passed the first voiding trial failed on subsequent trials, whereas 36.8% of patients who failed the first voiding trial succeeded. CONCLUSIONS: Postoperative voiding dysfunction is transient and is associated with the immediate voiding conditions following surgery. Close observation against urine overload in the bladder is important when weaning patients back to normal voiding conditions.

PURPOSE: Treatment of impotence has advanced considerably by an orally active, effective and well-tolerated drug, sildenafil citrate. However, Sildenafil citrate is not so effective for the treatment of severe organic impotence patients. Intracavernosal injection of vasoactive substance is still the most effective therapy for those patients but side effects, e.g. pain, priapism, require a more comfortable therapy. We performed this study to assess the feasibility of sildenafil citrate as a new intracavernosal agent. MATERIALS AND METHODS: In New Zealand white male rabbits (n=11), relaxations of precontracted cavernosal smooth muscle strips were studied after administration of sildenafil citrate, acetylcholine and sodium nitroprusside (SNP), respectively. In separate in vivo experiment, changes of intracavernosal pressure (ICP), duration of increased ICP and changes of systemic arterial blood pressure after retrograde selective internal pudendal arterial administration of four separate doses (0.1 mg, n=5; 0.3 mg, n=6; 0.5 mg, n=7; 1.0 mg, n=7) of sildenafil citrate were monitored in adult male cats (n=25). RESULTS: Acetylcholine, SNP and sildenafil citrate effectively relaxed the precontracted strips in a dose-dependent manner (3x10 8-3x10 3 M), respectively. Maximal relaxation of strips to acetylcholine, SNP and sildenafil citrate were 50.11%, 98.65%, and 68.32%, respectively.

Nuclear protein-1 (NUPR1) is a small nuclear protein that is responsive to various stress stimuli. Although NUPR1 has been associated with cancer development, its expression and roles in cholangiocarcinoma have not yet been described. In the present study, we found that NUPR1 was over-expressed in human cholangiocarcinoma tissues, using immunohistochemistry. The role of NUPR1 in cholangiocarcinoma was examined by its specific siRNA. NUPR1 siRNA decreased proliferation, migration and invasion of human cholangiocarcinoma cell lines (HuCCT1 and SNU1196 cells). From these results, we conclude that NUPR1 is over-expressed in cholangiocarcinoma and regulates the proliferation and motility of cancer cells.

Bladder leiomyoma is a very rare tumor, and only 0.43% of bladder tumors are of this type. Bladder leiomyoma may cause various symptoms depending on its anatomical location and size. The most common voiding symptoms manifested by leiomyoma are the obstructive symptoms. We report a case of a 42 year old woman who had voiding symptoms for 3 years while visiting the outpatient department of genito-urology due to acute urinary retention. We performed ultrasonography, computed tomography, MRI and transurethral resection, and from these test, the pathologic diagnosis revealed a leiomyoma of bladder.

Takayasu's arteritis is a chronic inflammatory disease of unknown etiology involving the thoracic and abdominal aorta and its major branches. In some cases other vessel such as renal arteries, coronary arteries, and even pulmonary arteries may be involved. Total aortography is very important, because the clinical features are determined by the extent and severity of the specific artery involved in the occlusive phase of the disease. We report a case of Takayasu's arteritis type IV in a 38 year man with pulmonary arterial involvement and pulmo-nary hypertension.

PURPOSE: Successful treatment of bladder cancer greatly depend upon the regular surveillance for early detection of persistent or recurrent cancer. We assessed the efficacy of urinary NMP22 test in screening and post-trearment follow-up for bladder cancer. MATERIALS AND METHODS: Urinary NMP22 test kit, which is based on an enzyme-linked immunosorbent assays, were used to measure the values of urinary NMP22 in 30 patients of transitional cell carcinoma of the bladder, 32 healthy volunteers, 12 patients of urinary tract infection and 13 patients of other urinary malignancy. RESULTS: Median values of urinary NMP22 in patients with bladder cancer were significantly greater than in healthy volunteers(p<0.05). With a cutoff value of 15units/ml, urinary NMP22 test had a 90.0% of sensitivity and a 90.6% of specificity in predicting bladder cancer. There was significant postoperative decrease of urinary NMP22 values in all patients with bladder cancer(p<0.05). CONCLUSIONS: These results suggest that urinary NMP22 test is useful for screening and postoperative surveillance of patients with transitional cell carcinoma of urinary bladder. Further comparative studies of urinary NMP22 test with the results of postoperative cystoscopy or cold cup biopsies are requested to enhance the practical utility of urinary NMP22 test.

Localized scleroderma is a disease of unknown origin and is characterized by circumscribed sclerotic skin changes. When occurring in a linear pattern, it is called linear scleroderma. 'En coup de sabre' is a subtype of linear scleroderma which is characterized by band-like, ivory-colored depressions on the frontoparietal scalp region. Several treatment modalities have been used. However, they have not been effective or safe. We report our experience of two patients with 'en coup de sabre' on the forehead, who were treated successfully with polymethylmethacrylate microspheres (PMMA-NewPlastic(R)).

PURPOSE: The present study was done to define the degree of intravesical prostatic protrusion (IPP) causing bladder outlet obstruction (BOO) in patients with benign prostatic hyperplasia (BPH)/lower urinary tract symptoms. MATERIALS AND METHODS: We retrospectively evaluated 239 patients with BPH, analyzing age, IPP, prostate volume, International Prostate Symptom Score (IPSS), and the results from a pressure-flow study. Urethral resistance was quantified by using the BOO index (BOOI), according to the formula BOOI=PdetQmax-2xQmax (where Pdet is detrusor pressure at the peak flow rate and Qmax is peak flow rate). BOO was defined by a BOOI above 40. Patients with a BOOI below 20 were excluded. Patients were classified into two groups (obstructed and unobstructed groups) by the BOOI. Correlations were determined by logistic regression analysis, and receiver operating characteristic curves were plotted to estimate the optimal cutoff for IPP. RESULTS: There were significant differences in total prostate volume, postvoiding residual urine (PVR), IPP, and Qmax (p<0.001, p<0.001, p<0.001, and p=0.026, respectively) between the obstructed and unobstructed groups, but there were no significant differences in age (p=0.653), IPSS total score (p=0.624), or quality of life score (p=0.138). IPP had a significant prognosis (p<0.001) but was weakly correlated with prostate volume (p=0.026). The correlation coefficients between IPP and Qmax, PVR, prostate volume, and BOO were 0.551, -0.159, 0.225, and 0.391, respectively. For IPP, the area under the curve was 0.759 (95% confidence interval, 0.657 to 0.861) and the cutoff to indicate BOO was 5.5 mm with 66.7% sensitivity and 80.5% specificity. CONCLUSIONS: An IPP exceeding 5.5 mm was significantly associated with BOO.
