The susceptibility of radiata pine sapwood to fungal attack and the ability of selected fungicides to control colonization of sapstain and mold fungi on green radiata pine sapwood were evaluated. Radiata pine sapwood was highly susceptible to fungal staining, suggesting that prompt application of fungicides after sawing is essential for preventing fungal colonization. The ability of commercial fungicides to prevent fungal discoloration on radiata pine sapwood was assessed using an accelerated 6-week test on small samples in the laboratory, and in field tests using bulk-piled boards exposed outdoors for 6 weeks during summer rainy season. In laboratory tests, Hylite extra provided excellent protection against fungal discoloration even at the lowest concentrations. Hylite clear, Britewood S, and NP-1 Plus provided good short-term protection (2 to 4 weeks), but higher chemical loadings were required for long-term protection (6 weeks). Woodguard produced little or no protection over the test periods. In field tests, Kathon 893 provided markedly superior protection at the concentration of 0.5 percent or higher. NP-1 Plus provided relatively good protection at all concentrations evaluated. Hylite extra was effective only for short-term protection (2 to 4 weeks) at all concentrations tested, but higher solution strengths were needed for long-term protection.

OBJECTIVE: Facial nerve palsy is a common complication of treatment for vestibular schwannoma (VS), so preserving facial nerve function is important. The preoperative visualization of the course of facial nerve in relation to VS could help prevent injury to the nerve during the surgery. In this study, we evaluate the accuracy of diffusion tensor tractography (DTT) for preoperative identification of facial nerve. METHODS: We prospectively collected data from 11 patients with VS, who underwent preoperative DTT for facial nerve. Imaging results were correlated with intraoperative findings. Postoperative DTT was performed at postoperative 3 month. Facial nerve function was clinically evaluated according to the House-Brackmann (HB) facial nerve grading system. RESULTS: Facial nerve courses on preoperative tractography were entirely correlated with intraoperative findings in all patients. Facial nerve was located on the anterior of the tumor surface in 5 cases, on anteroinferior in 3 cases, on anterosuperior in 2 cases, and on posteroinferior in 1 case. In postoperative facial nerve tractography, preservation of facial nerve was confirmed in all patients. No patient had severe facial paralysis at postoperative one year. CONCLUSION: This study shows that DTT for preoperative identification of facial nerve in VS surgery could be a very accurate and useful radiological method and could help to improve facial nerve preservation.

BACKGROUND: The effects of omega-3 polyunsaturated fatty acids (PUFAs) on cerebral vessels have not been clarified until now. Thus we investigated the efficacy of omega-3 PUFAs supplementation on cerebral blood flow velocity and vascular resistance via transcranial doppler (TCD). METHODS: Consecutive twenty patients (13 male and 7 female) with at least 1 cerebrovascular risk factor or a known cerebrovascular disease were enrolled. Patients were treated with omega-3 PUFAs (1 g, two times per day) for 12 weeks. Cerebral blood flow velocity, resistance index, and pulsatile index were checked before and after 12 weeks of treatment using TCD. RESULTS: The change of resistance index in right MCA (from 0.58 +/- 0.07 to 0.55 +/- 0.07, p = 0.042) and left PCA (from 0.56 +/- 0.07 to 0.53 +/- 0.06, p = 0.037) showed significant improvement after 12 weeks of omega-3 PUFAs treatment. The changes in other vessels, however, failed to show any significant changes compared to the baseline. CONCLUSIONS: Omega-3 PUFAs treatment showed feasible efficacies for cerebral vascular resistances in this open label trial. To confirm these results, larger samples of patients and longer period of follow-up is warranted.

The Korean sawmills have recently recognized the importance of prevention of fungal discoloration due to increased losses in revenue. Before establishing integrated control strategies of fungal discoloration, more complete knowledge about causal organisms is needed. As a first step, we initiated a through survey of fungi colonizing commercially important softwood (Pinus densiflora, Pinus koraiensis, and Pinus radiata) logs and lumber in Korea. In this paper we report results obtained from Japanese red pine (Pinus densiflora) log study. In summer 2000, fungi were isolated from Japanese red pine logs in storage, and identified based on their cultural and morphological characteristics. A total of 595 fungi were isolated, representing 21 genera and 30 species. Mold fungi, mostly Trichoderma species, were the most frequently isolating fungi, representing more than half of all isolates. Dematiaceous fungi represented approximately one fifth of the isolates, and Rhinocladiella atorvirens was the most abundant in all samples. Opiostoma species represented 7% of all isolates from cores planted on malt extract agar (MEA) and the incidence of these species doubled with the addition of streptomycin and cycloheximide to MEA. The results indicate that Japanese red pine sapwood is susceptible to colonization by a variety of fungal species. As a result, control strategies that concentrate on one fungus may have limited success because of interference from competing flora.

Klinefelter's syndrome (KFS) is a gonosomal aberration disease that occurs in males, and is characterized by 47, XXY karyotype, hypogonadism and a lack of secondary sexual characteristics. A potential link between this hormonally deficient syndrome and autoimmune disease, particularly systemic lupus erythematosus (SLE), has been reported. On the other hand, KFS is rarely reported to be accompanied by rheumatoid arthritis (RA), and there are no Korean cases reported. We report the first Korean case of a KFS patient with sero-positive RA and discuss the role of the pathogenesis of RA with KFS.

Sweet's syndrome is characterized by a constellation of clinical symptoms, physical features, and pathologic findings, which include fever, leukocytosis, tender erythematous skin lesions, and a diffuse infiltrate consisting predominantly of mature neutrophils in the upper dermis. Pulmonary involvement in Sweet's syndrome is rare. In addition, a pleural effusion has been rarely reported in the pulmonary involvement of Sweet's syndrome. We report a case of Sweet's syndrome presenting with pulmonary involvement and a bilateral pleural effusion in a patient with myelodysplastic syndrome.

PURPOSE: The purpose of this study is to analyze the treatment strategies of patients with endoscopic retrograde cholangiopancreatography (ERCP)-related perforations. This is a retrospective study. METHODS: We experienced 13 perforations associated with ERCP. We reviewed the medical recordsand classified ERCP-related perforations according to mechanism of injury in terms of perforating device. Injury by endoscopic tip or insertion tube was classified as type I, injury by cannulation catheter or sphincterotomy knife as type II, and injury by guidewire as type III. RESULTS: Of four type I injuries, one case was managed by conservative management after primary closure with a hemoclip during ERCP. The other three patients underwent surgical treatments such as primary closure orpancreatico-duodenectomy. Of five type II injuries, two patients underwent conservative management and the other three cases were managed by surgical treatment such as duodenojejunostomy, duodenal diverticulization and pancreatico-duodenectomy. Of four type III injuries, three patients were managed conservatively and the remaining patient was managed by T-tube choledochostomy. CONCLUSION: Type I injuries require immediate surgical management after EPCP or immediate endoscopic closure during ERCP whenever possible. Type II injuries require surgical or conservative treatment according to intra- and retro-peritoneal dirty fluid collection findings following radiologic evaluation. Type III injuries almost always improve after conservative treatment with endoscopic nasobilliary drainage.

The remnant cystic duct or gallbladder neck calculus may rarely result in post-cholecystectomy Mirizzi syndrome. Various managements have been proposed for the treatment of post-cholecystectomy Mirizzi syndrome. Some previous cases of post-cholecystectomy Mirizzi syndrome have been managed with open cholecystectomy and endoscopically. We report a case of a laparoscopic stone removal of post-cholecystectomy Mirizzi syndrome that developed 7 months after laparoscopic cholecystectomy. To our knowledge, this is the first case of laparoscopic management of post-cholecystectomy Mirizzi syndrome. The mechanism, diagnosis and treatment of post-cholecystectomy Mirizzi syndrome are discussed.
