PURPOSE: Forty percent of the newly diagnosed bladder cancer patients are over the age of 70 years, but it is said that over 75% of them are excluded from active programs of management. This study was to evaluate the usefulness of M-VAC(methotrexate, vinblastine, adriamycin and cisplatin) chemotherapy for invasive bladder cancer patients over the age of 70 years compared with that of patients under the age of 70 years. MATERIALS AND METHODS: Sixty patients with invasive bladder cancer were treated with M-VAC chemotherapy. We divided the patients into group 1- 20 patients over the age of 70 years and group 2- 40 patients under the age of 70 years. We compared cycle length, toxicity and clinical response of M-VAC chemotherapy in group 1 with those of group 2. RESULTS: The Karnofsky performance score was 85.5% in group 1 and 96.3% in group 2. The cycle length needed for 2 cycle of M-VAC chemotherapy was 67.2(range, 56-92) days in Group 1 and 61.5(range, 56-78) days in Group 2(p>0.05). Hematologic toxicities had not significant difference between two groups. Vomiting and stomatitis occurred more common in group 1. In 3 patients of group 1, the serum creatinine level rose to more than 3 mg/dl. The clinical response was 50% in Group 1 and 67% in Group 2(p>0.05). CONCLUSIONS: The bladder cancer patients over the age of 70 years had much more toxicity, longer cycle length and lower response rate, but these differences had not statistical significance. These results suggest that M-VAC chemotherapy in patients over the age of 70 years will achieves the therapeutic effects when the patients have a good physical condition and toxicities to chemotheraphy are monitored closely.

We report a case of renoduodenal fistula resulting from papillary renal cell carcinoma. A 72-year-old woman presented with nausea, diarrhea and abdominal discomfort. Abdominal CT, UGI and sinography revealed fistula between the right renal mass and the duodenum. Radical nephrectomy and duodenal wedge resection was performed and a friable mass with a fistula between the lower pole mass of the right kidney and second portion of the duodenum was found. Histologic evaluation for renal mass showed papillary renal cell carcinoma. We describe this case and review the previously reports of renoduodenal fistulae.

PURPOSE: The detection of bladder cancers by noninvasive techniques remains an unsolved problem. We evaluate the availability of an immunoassay for urinary nuclear matrix protein, NMP 22, as an indicator for transitional cell carcinoma of the bladder. MATERIALS AND METHODS: Three groups of subjects participated in this trial of NMP 22: 22 patients with transitional cell carcinoma (group 1), 12 patients with urinary tract infection (group 2) and 31 healthy volunteers (group 3). NMP 22 was determined by ELISA using a commercial test kit (NMP 22 Test Kit, Matritech Inc., USA), We compared urinary NMP 22 levels to the grade, stage, cytology and DNA flowcytometry of transitional cell carcinoma of bladder. RESULTS: NMP 22 values in these 3 groups were significantly different (group 1, median 24.81 U/mL; group 2, median 8.41 U/mL; and group 3, median 5.12 U/mL; Mann-Whitney U test for differences between 3 medians, p < 0.05). The patients with transitional cell carcinoma had significantly greater urinary NMP 22 levels than those with no evidence of tumor (Mann-Whitney U test for differences between 2 medians, p<0.01). There was no zelationship between the urinary NMP 22 levels and tumor grade, stage, cytology or DNA flowcytometry. CONCLUSIONS: It is possible that urinary NMP 22 could improve the detection of bladder transitional cell carcinoma.

PURPOSE: Sexual dysfunction has been reported to be frequent in patients with acute myocardial infarction. One aim was to correlates the erectile function with the severity of coronary arterial disease in the acute myocardial infarction patients. MATERIALS AND METHODS: A total of 57 men, median age 55.7 years (range 29 to 81), with acute myocardial infarction who had received coronary angiography were evaluated about their erectile function with 15-item questionnaire, the International Index of Erectile Function (IIEF). History of vascular risk factors such as smoking, diabetes mellitus, and hypercholesterolemia were obtained. We compared the erectile function score to the number of occluded coronary vessels or patients age. RESULTS: One coronary vessel was involves in 16 patients (28.1%), more than 2 coronary vessels were involved in 25 patients (43,9%) while 16 patients (28.1%) showed free of occlusion. Seventy-four percent of patients claimed abnormal erectile function, mild erectile dysfunction in 19 patients (33.3%), moderate in 9 patients (15.8%), severe in 14 patients (24.6%). Erectile function score decreased significantly according to increasing in the number of coronary vessels involved (p<0.05) and in patients age (p<0.01). CONCLUSIONS: There was a significant correlation between erectile function and the severity of the coronary arterial disease in acute myocardial infarction patients. The age of patients also had a negative effects on the erectile function.

Background:
Recurrent hemarthrosis following total knee arthroplasty (TKA) is a rare complication. Its pathophysiology and standard treatments have not yet been established. In this study, we report 7 cases of recurrent hemarthrosis after TKA in which failure of the initial conservative treatment was followed by angiographic embolization; in 1 of the 7 cases, arthroscopic electrocauterization was also performed after treatment failure with selective embolization.
Methods:
From January 2015 to May 2018, 7 patients visited our hospital due to recurrent hemarthrosis after TKA. Their medical records and serologic test results were reviewed to check for the presence of any bleeding disorder and history of anticoagulant use. Implant malalignment and instability were checked using X-ray. In all cases, the conservative treatment failed, so interventional angiography with selective embolization was performed, which was also followed by arthroscopic electrocauterization if the outcome was unsatisfactory.
Results:
The interval between TKA and the onset of hemarthrosis ranged from 3 to 76 months (average, 34.1 months). There was no coagulopathy and instability. All patients underwent conservative treatment at an interval of 4.3 months and the rate of relapse was 3.1 on average. On the interventional angiography, 6 cases showed vascular blush, and 1 case had pulsatile bleeding. The average duration for interventional angiography was 90.9 minutes. The average length of follow-up was 38.8 months. Embolization was successfully performed in 4 cases. In 2 of 3 failed cases, the symptoms improved without further treatment. In the remaining 1 failed case, the patient had a relapse of hemarthrosis, so an arthroscopic procedure was performed, which led to identification of the suspicious bleeding point by using preoperative angiographic findings. Electrocauterization was performed and active bleeding was stopped. All cases with recurrent hemarthrosis achieved improvement.
Conclusions
Interventional angiography was used to aid in the diagnosis of recurrent hemarthrosis, and therapeutic selective embolization provided satisfactory clinical results. Even if selective embolization fails, interventional angiography may be helpful for further surgical procedures because it reveals vascular blush of a bleeding site. Therefore, interventional angiography and selective embolization should be considered to be a useful treatment for recurrent hemarthrosis after TKA.

Antipsychotics are the drug of choice for patients with schizophrenia, but they can induce hyperprolactinemia and growth of pituitary adenomas by blocking dopamine 2 receptors in the pituitary gland. In contrast, the medical treatment for a prolactinoma is a dopamine agonist. Therefore, managing a patient concurrently diagnosed with a prolactinoma and psychosis is challenging. We describe a patient with schizophrenia who was diagnosed with a prolactinoma. We changed his neuroleptic to quetiapine and prescribed bromocriptine for the prolactinoma. As a result, the patient was successfully treated with a dopamine agonist and antipsychotic without psychotic exacerbation. Our case suggests that dopamine agonists can be administrated to patients with schizophrenia and a prolactinoma without adversely affecting their psychopathological status.

Clinical and Molecular Hepatology 2021;27(3):451-462
Background/Aims:
To analyze the incidence and risk factors of outcomes after liver transplantation (LT) in the Korean population.
Methods:
This study analyzed data from the liver cohort of Korean Organ Transplantation Registry (KOTRY) who had LT between May 2014 and December 2017. Study measures included the incidence of post-LT outcomes in recipients of living donor LT (LDLT) and deceased donor LT (DDLT). Cox multivariate proportional hazards model was used to determine the potential risk factors predicting the outcomes.
Results:
A total of 2,563 adult recipients with LT (LDLT, n=1,956; DDLT, n=607) were included, with mean±standard deviation age of 53.9±8.9 years, and 72.2% were male. The post-LT outcomes observed in each LDLT and DDLT recipients were death (4.0% and 14.7%), graft loss (5.0% and 16.1%), rejection (7.0% and 12.0%), renal failure (2.7% and 13.8%), new onset of diabetes (12.5% and 15.4%), and hepatocellular carcinoma (HCC) recurrence (both 6.7%). In both LDLT and DDLT recipients, the most common post-LT complications were renal dysfunction (33.6% and 51.4%), infection (26.7% and 48.4%), and surgical complication (22.5% and 23.9%). Incidence of these outcomes were generally higher among recipients of DDLT than LDLT. Multivariate analysis indicated recipient age and DDLT as significant risk factors associated with death and graft loss. DDLT and ABO incompatible transplant were prognostic factors for rejection, and HCC beyond Milan criteria at pre-transplant was a strong predictor of HCC recurrence.
Conclusions
This study is a good indicator of the post-LT prognosis in the Korean population and suggests a significant burden of post-LT complications.
