In this study noise source in a ward at four general hospitals in Seoul area has investigated and analysed. The degree of reaction against noise by 171 randomly has also been examined. The results of the study have shown that the source of noise is the speakers of wired broadcasting or from visiting guests in two hospitals located in residential area. The patients at the two other hospitals located at commercial site have been suffered more from traffic noise, However, because of their separated living at hospital from their ordinary houselife, sixty on percent of the inpatients have wished a music sound of around 60 dB (A). After having considered the results of the investigation and wishes of the inpatients, following suggestions have been made: 1. Reduce the number of guests or their length of stay. 2. Wired bodadcasting system should be substitued by sireless one, or if it's unavoidable, it should be used in office rooms only. 3. Since the stops and starts of vehicles induce much noise, Seoul City Government be requested to prepare an appropriate administrative measure for the vehicles around hospital area and ti should prevent the establishment of new hospitals along high way site. 4. By using earphone, inpatients can choose a wireless channel according to each individual's taste. This through the masking effect, would cover up the noise source. 5. Rooms along the streets should be utilized as offices, otherwise double windows should be set up for inpatient's wards.

Rahnella aquatilis, an infrequently isolated gram-negative rod, is the only species of the genus Rahnella within the Enterobacteriaceae family. The organism's natural habitat is water, from which most isolates have been recoverd. Infecions in humans have only occasionally been reported, especially in immunocompromised patients. We reort a case of bacteremia caused by this organism in a hemodialysis patient.

PURPOSE: The aim of this study was to evaluate the effectiveness and indication of radiofrequency ablation(RFA) using renal VX2 tumors by implantation of VX2 tumor cells under the renal capsule in rabbits. MATERIALS AND METHODS: Ten rabbits were injected with 30-40microliter VX2 tumor cells(1.2x10(7) viable cells/ml) under the renal capsule of the right kidney by right subcostal incision. On the 14th day after the tumor cells were implanted, we checked for the development of renal tumors, and the sizes and shapes(exophytic or central) of the tumors by the use of computed tomography. We performed RFA in the renal VX2 tumors with a 17G StarBurst electrode through kidney exposure. After the first and third day following RFA, renal function was checked. On the third day, we performed CT and harvested the kidneys for gross and microscopic evaluation. RESULTS: We confirmed the development of renal VX2 tumors in nine cases. Tumor shapes were exophytic in seven cases and central in two cases; the mean size of the tumors was 2.1 cm(range, 1.1-3.8cm). In all tumors, RFA was performed. From the use of enhanced CT after RFA on the third day, all of the lesions treated with RFA showed no enhancement. From the pathological findings, coagulative necroses were seen on all of the lesions treated with RFA. The necrotized tumor size after RFA was not different statistically as measured by CT and a pathological examination (p=0.833) CONCLUSIONS:: In centrally located renal tumors, we experienced thermal injury in pelvocalyceal systems. RFA is an effective method for nephron sparing surgery as the tumor cells completely disappear and there is preserved renal function and the procedure is easy to apply. We suggest that the RFA method for exophytic renal tumors is more effective than other procedures.

Rectal syphilis, known as a great masquerader, can be difficult to diagnose because of its variable symptoms. Gastroenterologists should be aware of the possibility of rectal syphilis when confronted with anorectal ulcers, and should gather a detailed history about sexual preferences and practices, including homosexuality. We report a case of primary rectal syphilis mimicking rectal cancer on radiologic imaging. In this report, we described the clinical, endoscopic, and radiologic features of this rare case.

PURPOSE: The purpose of this study was to compare the surgical outcomes of two different surgical methods for varicocelectomy, and to assess the effects of varicocelectomy on semen parameters in subinfertile men. MATERIALS AND METHODS: This study included 63 patients with clinically palpable varicocele and abnormal semen parameters who underwent varicocelectomy. Thirty-three patients underwent laparoscopic varicocelectomy, and 30 received microsurgical inguinal varicocelectomy. Semen analyses were performed 5.3 months later, and compared with the pre-operative data. RESULTS: The mean age of patients was 32.1+/-1.3 years old. Comparison of the semen parameters between pre and post-varicocelectomy revealed significant improvement in the sperm count (p<0.05). In laparoscopic and microsurgical inguinal varicocelectomy, the sperm counts were increased from 16.2+/-4.3 to 30.6+/-7.5 and from 15.4+/-3.8 to 37.5+/-7.7, respectively. Sperm motility also tended to improve. CONCLUSIONS: Varicocelectomy enhanced semen parameters after both laparoscopic and microsurgical methods. In subfertile men, early varicocelectomy is recommended.
