BACKGROUND: Recently developed electrically stimulated gracilis neosphicter or artificial sphincter is quite a promising trial in fecal incontinence However, surgical technique is not simple, the devices are expensive and only specialists can perform the procedures successfully. The aim of this study is to evaluate the efficacy of a newly developed simple silicon device in incontinent dog model. METHODS: A New Colostomy Device (NCD; US Patent No. 5,569,216) for fixing in the stoma or rectum of human body, includes an internal balloon, a ring figured extemal balloon surrounding the internal balloon, a connecting tube disposed under the both infernal and external balloons and supply tube containing a pair of air passages and an enema fluid passage. It is designed to be inserted into the rectum and is held in place by an inflatable external balloon and drains irrigated fecal matter through a thin collapsible connecting tube which exist in the anal canal. Six mongrel dog with 22~26 kg of body weight were prepared. Anal incontinence was made by bilateral severing of the internal and external sphincters and puborectalis muscle under the general anesthesia. Marlex mesh ring was applied to the anal canal as Thiersch wire for the prevention of NCD expulsion in straining. After then, NCD with 2.5 cm of luminal diameter was inserted to the rectum proximal to the Malex mesh ring. Daily irrigation and evacuation was done with 800~1000 cc of tepid water in each dogs. Daily food contained 30 gm of Psyllium dextrose. RESULTS: Initially 6 dogs were observed for 7 days. Daily irrigation made evacuation of fecal matter well in each dogs. There was no prolapse of device through the anal orifice. Anoscopic examination after 7 days showed no rectal and anal mucosal injury. Two dogs were kept for 40 days as same manner. Sometimes spontaneous bowel movement without water irrigation was noted when the stool were loose. Weelky anoscopic examination revealed no evidence of mucosal injuries for 40 days also. There was no septic or other complication. CONCLUSION: NCD evacuated fecal matter well enough to empty the rectum in all incontinence dog model. Adequate sized NCD could be used for clinical trials in selected incontinence patients.

Vivax malaria, which was once thought to be eradicable since more than 20 years ago, has made a dramatic resurgence since 1993 in the northern parts of Kyeonggi-do in the background of 0.13 of the annual parasite incidence in the population of 956,773 and 2 positives (0.07%) of asymptomatic parasitaemia among the 2,937 residents of mass blood survey in the area in 1969. The majority of the cases were soldiers infected in several counties located within 5 km from the Demilitarized Zone (DMZ) in 1994. Since then, malaria cases have increased and have tended to expand toward eastern and southern areas. Korean malaria is characterized by asymptomatic parasitaemia with long prepatent period, so malaria cases, including those manifesting as general fever should be treated with a combination of chloroquine and pyrimethamine to prevent the completion of sporogonic cycle in the mosquitoes. For the most effective control of vector mosquitoes, residual insecticides should be applied in the military houses and animal shelters with thermal fogging, including the control of the pre-stages of physiological age of the mosquitoes within 25 km from the DMZ. It is strongly suggested that military uniforms be treated with 0.5% permethrin complex (permethrin 39%+cyfluthrin 1%) or permethrin formulation. Further genetic studies are desired to determine the subspecies of Plasmodium vivax because Korean strain of malaria is likely to be a complex form of Plasmodium vivax vivax and Plasmodium vivax hibernans.

BACKGROUND: Postherpetic neuralgia is usually defined as pain persisting for more than one month after the onset of the eruption of herpes zoster, although there is a overlap between this and the pain of the acute zoster. Many approaches have been proposed to treat postherpetic neuralgia, however, it remains a source of frustration for both patients and physicians. OBJECTIVE: The purpose of this study was to determine more precisely the relationship between the effects of continuous epidural blockade and the time of treatment on postherpetic neuralgia. METHODS: We analyzed the results of 5 patients with postherpetic neuralgia for whom continuous epidural blockade was performed within 1 month after the onset of postherpetic neuralgia, and compared them with the results of 5 patients for whom continuous epidural blockade was performed after 1 month after the onset of postherpetic neuralgia. RESULTS: Continuous epidural blockade performed within 1 month after the onset of postherpetic neuralgia reduced pain significantly, compared to the results of continuous epidural blockade performed after 1 month after the onset of postherpetic neuralgia. CONCLUSION: Continuous epidural blockade performed within 1 month after the onset of postherpetic neuralgia may be the treatment of choice for the pain.

An epidemiological study on brugian filariasis was carried out in endemic areas including Cheju Island in Korea, with a brief review of literatures.The results showed that the incidence among residents has remarkably decreased in Cheju Island, which was the main endemic area. Reviewing available informations on the prevalence of filariasis reported in recent years and also judging from the present socio-economic conditions which enable people to practice personal protection against mosquitos, it can be said with confidence that filariasis has almost disappeared from Cheju Island and inland areas. The disease is considered to remain at a low level of endemicity in Hugsan Islands. Certainly mass diethylcarbamazine (DEC) treatment carried out in Cheju Island in the 1960s and 1970s and remarkable economic growth followed by improved living standard and altered life-style of inhabitants could all have combined effects on the disappearance of this mosquito-borne diseae in this island. If the present trends go on, the possibility of resurgence of filariasis in Cheju Island is hardly postulated.

Since the national malaria eradication service (NMES) was implemented in 1959, extensive malariometric survey were conducted throughout the country. A total of 73,859 malaria cases of Plasmodium vivax were confirmed out of 268,259 blood smears through passive and active case detection (PCD and ACD) in 1960~1969 including chloroquine/ pyrimethamine combined tablets for the presumptive treatment of all of fever cases. The majority of the positive cases occurred in Gyeongsang buk-do, revealing 62,859 cases as of 85.2%, followed by Gyeonggi-do 5,844 cases (7.9%), Chungcheong buk-do 3,458 cases (4.7%), Gangwon-do 812 cases (1.1%), and 29 cases developed in Jeju-do. ACD was more sensitive and advantageous for detecting the malaria cases over PCD in the pilot study area. The high endemic area was located in the north Gyeongsang buk-do and north east Gyeonggi-do. The malaria incidence was high in the age group under 14 years in malaria foci, and that was low in non-malarious area. High parous rate (77.7%) and survival rate (91.4%) of the vector mosquitoes were shown in malaria foci, which were hilly or mountainous area. On the other hand, low parous rate (50.6%) and survival rate (42.7%) were found in non-malarious area, the rice field of south western part of the country even in abundance of vector mosquitoes. NMES had contributed the control of the malaria by carring out the residual DDT focal spray, mass drug administration, radical treatment of the positive cases, and mass blood survey in the heavy malarious area. Since then malaria disappeared rapidly, and no indigenous case was reported after 1984. In order to ascertain whether this country was malaria-free or not, mass blood survey was carried out for the juveniles, adolescents and adults in Yeongju-gun Gyeongsangbuk-do in 1986 where the highest incidence of malaria was recorded during the 1960s. The result showed no positive case at all. However vivax malaria reemerged, and made a dramatic resurgence since 1993 in the demilitarized zone (DMZ) bordering North Korea, and expanded toward eastern and southern part of the country year after year, totaling 14,089 cases including U.S. army by the end of 2000 in spite of the strong activities of antimalaria in the Republic of Korea. So vector control including the encouragement of the livestock farming in the malaria endemic area must be more sensitive and effective measure to reduce the risk of malaria transmission by the eliminating the dangerous age of mosquitoes in the points of characteristics of the Korean strain of parasites such as the mild symptoms, long-term incubation period and asymptomatic parasitaemia. Focal application of thermal fogging and mist spray of insecticides would be certainly effective in preventing the vector mosquitoes from infecting the gametocytes of malaria for the first peak of multi malaria cases in the early season of the year. All of the civilians who are in the high risk area for malaria should be forced to sleep under the permethrin impregnated mosquito nets. All of the soldiers near the DMZ are strongly recommended to take the combined tablets of chloroquine/ pyrimethamine instead of the single base of chloroquine at present to prevent the action of source of infection of the reservoirs and the completion of the sporogonic stages of the vector mosquitoes because the vector control activities are not allowed in the DMZ. The experts of entomologists and malariologist of the South and North Korea should discuss the antimalaria programme to eradicate the malaria from the Korean peninsular near future.

PURPOSE: Recently developed BMS(TM) (Zassi Bowel Management System(TM): Hollister Inc., Illinois, USA) can provide effective nonsurgical fecal diversion without the risks associated with colostomy creation and subsequent closure. Our aim is to evaluate the effectiveness of the BMS in diverting feces from the perianal wide surgical wound in patients with Fournier's gangrene. METHODS: BMS(TM) was applied in five patients (male: 2, median age; 44) with Fournier's gangrene from January 2000 to September 2001. The treatments consist of three times a day wound dressing after wide surgical debridement and intravenous antibiotic therapy. For evacuation of feces, twice daily warm saline irrigation was administered via BMS(TM) or low daily doses of polyethylene glycol solutions were orally taken in. An endoscopic and anorectal manometric study was done to evaluate possible mucosal complications and anorectal functional changes. RESULTS: The average duration of the BMS application was 41 (range, 22~63) days. The result of a manometric study after immediate removal of the BMS(TM) showed a decreased mean resting pressure (range: 22~36 mmHg) and a decreased mean squeezing pressure (range: 32~39 mmHg). After 3 days, the sphincter pressure had improved markedly: mean resting pressures of 38, 45, 60, and 63 mmHg and mean squeezing pressure of 78, 89, 91, and 101 mmHg respectively. Fecal incontience was not noted in any patient. Other possible mucosal complications were not noted. There were no mortalit. CONCLUSIONS: BMS(TM) application in Fournier's gangrene patients after surgery successfully avoids a defunctioning colostomy. Furthermore, no significant complications were noted over a prolonged period up to 63 days.

BACKGROUND: The purpose of this study was to evaluate the postoperative magnetic resonance imaging (MRI) results of minimal-tying (one medial-row tie among 4 medial-row sutures) on the medial-row in double-row suture-bridge configuration (2x2 anchor with 4x4 suture stands). METHODS: From 2011 March to 2012 July, 79 patients underwent arthroscopic rotator cuff repair using 2x2 anchor double-row configuration. The mean age was 61.3 years (range, 31-81 years). Two double-loaded suture anchors were used for medial-row. Four medialrow stitches were made with only one medial-row knot-tying (the most anterior suture). Lateral-row was secured using the conventional suture-bridge anchor technique; all 4 strands were used for each anchor. Repair integrity was evaluated with MRI at mean 6.2 months postoperatively. Retear and the pattern of retear, change of fatty infiltration, and muscle atrophy of supraspinatus were evaluated using pre- and postoperative MRI. RESULTS: Repaired tendon integrity was 38 for type I, 30 for type II, 6 for type III, 4 for type IV, and 1 for type V, according to Sugaya classification. Considering type IV/V as retear, the rate was 6.3% (5 out of 79 patients). Medial cuff failure was observed in 4 patients. Fatty atrophy of supraspinatus was significantly improved postoperatively according to Goutallier grading (p=0.01). The level of muscle atrophy of supraspinatus was not changed significantly after surgery. CONCLUSIONS: Minimal tying technique with suture configuration of four-by-four strand double-row suture-bridge yielded a lower retear rate (6.3%) in medium to large rotator cuff tears.
