Intestinal malrotation with volvulus is generally presented as a bilious vomiting and acute intestinal obstruction in the newborn period. It could compromise vascular supply of the small bowel secondary to torsion of superior mesenteric artery (SMA) and without urgent surgical management, it could lead to detrimental outcomes such as transmural bowel infarction and sepsis. However, in chronic cases, it is rarely obstructs the vascular supply and propagates to an acute bowel infarction. Rarely, chronic malrotation with midgut volvulus may not reduce the mesenteric blood supply because of collateral vessels, and the chronically stagnated blood flow of the superior mesenteric vein (SMV) favors thrombus formation within the lumen. The recommended treatment is Ladd's procedure and anticoagulation therapy. The authors present an unusual case of intestinal malrotation with chronic volvulus resulting in superior mesenteric vein and portal vein thrombosis in a 28-year-old patient.

Microsatellites are short nucleotide repeat sequences present throughout the human genome. Alterations of microsatellites, comprising extra or missing copies of these se quences, have been termed microsatellite instability(MSI, genetic instability, replication errors, RER(+) phenotype). To date, at least four genes involved in DNA mismatch repair, hMSH2, hMLH1, hPMS1 and hPMS2, are thought to account for the observation of microsatellite instability in tumor from Hereditary nonpolyposis colorectal cancer (HNPCC) patients. The genetic defect responsible for the MIN+ phenotype in sporadic colorectal cancer, however, has yet to be clearly delineated. The purpose of this study was to determine the presence of MSI in sporadic cancer and to correlate its occurrence with clinicopathological parameters, we have studied six microsatellite loci by use of polymerase chain reaction amplification and denaturing polyacrylamide gel electrophoresis. We found that 20%(9 of 46 cases) sporadic colorectal cancers showed RER at two or several loci(RER+). Microsatellite instability was associated with location of the tumor in the proximal colon 66%(6 of 9 cases) and with poorly differentiated tumor phenotype 56%(5 of 9 cases). In order to better understand the role of somatic alterations within hMSH2 in the process of colorectal tumorigenesis, we examined the most conserved regions(codon 598~789) of this gene in nine patients with MIN spotadic colorectal cancer. 6 patient of RER(+) colorectal ca. patients had a polymorphism which was a T to C base change in the intron sequence at -6 position of the splice acceptor site at the 5'end of exon 13. This particular sequence variation is a polymorphism rather than a mutation which increase cancer susceptability. These data suggest that the genetic instability is detect ed in some colorectal cancers and play an important role in the pathogenesis of sporadic colorectal cancer.

OBJECTIVE: To evaluate the efficacy of sonohysterography on exact submucosal myoma. methods: Transvaginal sonohysterography was performed on 45 patients who diagnosed as submucosal myoma and 29 patients who diagnosed as endometrial polyp by classic abdominal or vaginal sonogram, and then they received the diagnostic hysteroscopy at all. RESULTS: In 24 of 45 patients on sonohysterogram, submucosal myoma was diagnosed that was protruded to uterine cavity more than 2/3 of mass. Nine patients had intramural myoma and 12 patients had myoma that protruded only lesser than 1/3 of mass on sonohysterogram. These 21 patients revealed the same finding on hysteroscopy. On hysteroscopy, submucosal myomas were in 20 of 24 patients and polyps were in 3 patients and synechia was in one patients. In 8 of 29 patients on sonohysterogram, endometrial hyperplasia was found and confirmed by hysteroscopy. In 16 of 21 patients whose finding was polyp on sonohsyterogram, polyp was confirmed by hysteroscopy. However hysteroscopic findings were myomas in 3 of 21 patients and synechia in one patients. Therefore in 29 of 74 patients (39.2%), further hysteroscopy was not needed by sonohysterogram. In 65 of 74 patients (87.8%), sonohysterographic findings were same as hysteroscopic findings. CONCLUSION: Sonohysterogram for diagnosis of submucosal myoma and polyp is essential procedure in order to avoid unnecessary hysteroscopy. However differentiation between polyp and submucosal myoma has still some difficulty.

The authors have analyzed the factors influencing the outcome of the 168 patients with acute epidural hematoma who had been managed in our hospital for 3 years from July 1986 to June 1989. 1) Sex incidence showed that male patients were 4.8 times more commonly affected than females, and the most commonly affected age group was the 3rd decade. 2) The most common cause of injury was motor vehicle accidents. The patients with unknown cause of injury which probably suggested significant delay in starting the clinical managements had a higher mortality rate. 3) The most common site of hematoma was the FTP convexity(63.6%). The patients with diffuse hematoma in the fronto-temporo-parietal region had a high mortality and deteriorated level of consciousness. 4) Skull fractures were not seen only in 9.5% of the patients with acute epidural hematoma. 5) The main factors associated with the higher mortality rate were rapid development of hematoma, pupillary dilatation, low score in Glasgow Coma Scale on arrival, and more midline shifting on brain CT. 6) The patients with concomitant intracranial lesions had a high mortality rate(25.8%), and the patients with acute epidural hematoma alone had a low rate(2%), and the overall mortality rate of the patients with acute epidural hematoma was 11.3%.

BACKGROUND: Despite numerous investigations, the pathogenesis of Meniere's disease is uncertain. Endolymphatic hydrops (ELH) has been the main histologic finding of Meniere's disease. Experimentally induced ELH in animal model has been developed in order to understand better the consequences of this morphopathology on inner ear structure and function. OBJECTIVES: The aim of this study is to develope the animal model of ELH. MATERIAL AND METHODS: We made an animal endolymphatic hydrops model on giunea pigs by mechanically obliterating the right endolympatic sac and duct. The left ears were used as a controls. RESULTS: After twelve weeks, the temporal bones were prepared for light and electron microscopic examination. The light microscopic study showed the distension and folding of Reissner's membrane, however other pathologic changes were uncertain in hydropic aminal. Under scanning electron microscopic examination, the cellular population of Reissner membrane remained normal but the microvilli of Reissner membrane were significantly decreased in hydrops group. The damage pattern of stereocilia were most severe in the apical turns, followed by the middle and the basal turns, in the order of severeity. The outer hair cell third row was most severely damaged in the entire cochlea, whereas the outer hair cell first row was relatively spared. On the single hair cell examination, abnormal distensions of the tip of stereocilia started from longer stereocilia. The number of microvilli on marginal cell was reduced in stria vascularis, but atrophic change was not observed.

BACKGROUND: Merkel cell carcinoma (MCC) is a rare locally aggressive cutaneous neuroendocrine carcinoma with a high incidence of local recurrence, regional lymph node metastasis, followed by distant metastasis. Because of shortage of the retrospective study, standard treatment has not been established. The purpose of this study was to present the surgical treatment and outcome of 8 patients with MCC. METHODS: We report our experiences with 8 patients who underwent treatment for MCC at our institution from 2000 through 2012. Two men and 6 women received treatment for MCC. The mean age was 76.4 years (range, 53 to 93 years). RESULTS: The follow-up period ranged from 7 to 26 months (mean, 22.9). During the follow-up period, three of 8 patients had a relapse (mean time before recurrence, 10 months; 1 month, 7 months, and 22 months). After primary surgery, 3 patients underwent radiotherapy, and 1 patient received chemotherapy. CONCLUSION: MCC is an aggressive skin cancer with a high rate of local recurrence. Complete surgical excision is the mainstay of local treatment, but adjuvant radiotherapy should be considered for better local control.

Epidermolysis bullosa dystrophica is a rare skin disease characterized by milia, nail dystrophy, andblistering of the skin and mucous membranes in response to minimal trauma. A forty years old man had typical skinlesions on the extremities, and the presence of distal phalangeal wedge deformity with soft tissue webbing wasnoted. multiple segmental strictures and ulceration involved the cervical and distal esophagus. Esophageal balloondilatation was therefore performed and dysphagia was relieved. The authors describe a case involving multipleesophageal strictures and musculoskeletal lesion, with clinically and radiologically documented epidermolysisbullosa dystrophica.

Perforations that occur during colonoscopy are usually managed by surgical repair. When the patient's symptoms are mild and laboratory findings show minor abnormalities, a conservative treatment can be considered. Although an operation is the treatment of choice in patients with generalized peritonitis, in some selected patients, percutaneous abscess drainage can be an alternative to surgical intervention for drainage of deep-infected fluid collections or can act as a temporary measure until the patient becomes sufficiently stable for surgery. We report here on a 53-yr-old male patient who developed signs of localized peritonitis and had a pelvic abscess due to a colonic perforation after colonoscopy and was treated successfully by using percutaneous abscess drainage.

BACKGROUND: Severe acute lung injury(ALI), also known as the adult respiratory distress syndrome(ARDS), is a heterogenous nature of dynamic and explosive clinical synrome that exacts a mortality of approximately 50%. Endotoxin(ETX) is an abundant component of the outer membrane of gram-negative bacteria capable of inducing severe lung injury in gram-negative sepsis and gram-negative bacterial pneumonia, which are among the most common predisposing causes of ARDS. The influx of PMNs into airway tissue is a pathological hallmark of LPS-induced lung injury. And th3re is a substantial evidence suggesting that cytokines are important mediators of lung injury in gram-negative sepsis. However, the kinetics of phagocytes and cytokines by an exact time sequence and their respective pathogenic importance remain to be elucidated. This study was performed to investigate the role of phagocytes and proinflammatory cytokines in ETX-induced ALl through a time course of changes in the concentration of protein, TNFa and IL-6, and counts of total and its differential cells in BALF. The consecutive histologic findings were also evaluated. METHOD: The experimental animals, healthy male Sprague-Dawley, weighted 200+/-50g, were divided into controland ALI-group. ALI was induced by an intravenous administration of ETX, 5mg/kg. Above mentioned all parameters were examined at 0(control), 3, 6, 24, 72 h after administration of ETX. TNFa and IL-6 conc. in BALE were measured by a bioassay. RESULTS: The protein concentration and total leukocyte count(TC) in BALF was significantly increased at 3h compared to controls(p<0.05). The protein conc. was significantly elavated during observation period, but TC was significantly decreased at 72h(p<0.05 vs. 24h). There was a close relationship between TC and protein cone. in BALF(r = 0.65, p <0.001). The PMN and monocyte count was well correlated with TC in BALF, and the correlation of PMN(r=0.97, p<0.001) appeared to be more meaningful than that of monoeyte(r = 0.61, p<0.001). There was also a significant correlation between protein cone. and PMN or monocyte count in BALF(PMN vs. monocyte r = 0.55, p<0.005 vs. r = 0.64, p<0.001). The count of monocyte was significantly elavated during observation period though a meaningful reduction of PMN count in BALF at 72h, this observation suggested that monocyte may, at least, partipate in the process of lung injury steadly. In this sudy, there was no relationship between IL-6 and TNFt conc., and TNFa but not IL-6 was correlated with TC(r 0.61, p <0.05) and monocyte(r = 0.67, p<0.05) in BALF only at 3, 6h after ETX introduced. In particular, the IL-6 cone. increased earlier and rapidly peaked than TNFz cone. in BALF. In histologic findings, the cell counts of lung slices were increased from 3 to 72h(p<0.001 vs. NC). Alveolar wallthickness was increased from 6 to 24h(p<0.001 vs. NC). There was a significant correlation between the cell counts of lung slices and alveolar wall-thickness(r= 0.61, p<0.001). This result suggested that the cellular infiltrations might be followed by the alterations of interstitium, and the edematous change of alveolar wall might be most rapidly recovered to its normal condition in the process of repair. CONCLUSION: We concluded that although the role of PMIN is partly certain in ETX-induced ALI, it is somewhat inadequate to its known major impact on ALL Alveolar macrophage and/or non-immune cells such as pulmonary endothelial or epithelial cells, may be more importantly contributed to the initiation and perpetual progression of ETX-induced ALI. The IL-6 in ETX-induced ALI was independent to TNFa, measured by a bioassay in BALF. The early rise in IL-6 in BALF implies multiple origins of the IL-6.

PURPOSE: In advanced colorectal cancer, 5-Fluorouracil (5-FU) and Leucovorin (LV) have been used as a standard chemotherapy regimen. 5-FU is a popular chemotherapeutic drug for colorectal cancers and LV is the most effective modulator of 5-FU. Recently, some studies using Interferon (INF) combination therapy with 5-FU to enhance the anti-tumor effect of 5-FU have been performed. The outcomes were reportet to be better than those of studies using single agent therapy. However, the clinical effect of a combination therapy with INF is still controversial. So that, we performed this study to understand the advantages of INF combination therapy in advanced colorectal cancers in the Korean population. METHODS: We recruited patients who had been diagnosed with for colorectal cancers and received operations and postoperative adjuvant chemotherapy in Uijongbu St. Mary's hospital, from July, 1995, to June, 1999. The patients were divided into two groups; control group treated with the Mayo clinic chemotherapy regimen of 5-FU plus LV, and study group treated with additional INF-alpha to 5-FU-LV combination treatment. We evaluated the clinical outcomes such as the overall survival rate, the recurrence rate, and the chemotoxicity between two groups. RESULTS: In comparison of 5 year survival rates of two groups for each stage of the colorectal cancer, those of stage B2 were 90.9% in the control group and 80.0% in the study group. For stage C patients, the values were 80.2% in control group and 52.5% in the study group. The overall 5-year survival rates of the control group and the study group regardless of stages were 77.1%, and 63.4%, respectively. The 5-year disease-free survival rates for stage B2 were 82.8% in the control group and 72.9% in the study group. For stage C patients, those were 42.6% in the control group and 34.4% in the study group. The recurrence and metastatic rates were 19.2% (local recurrence; 2, metastasis; 12) in the control group and 36.1% (local recurrence; 3 metastasis; 27) in the study group. The overall incidences of chemotoxicity were 24.7% in the control group and 31.3% in the study group. CONCLUSIONS: There was no evidence that chemotherapy using 5-FU and LV combined with INF-alpha in advanced colorectal cancer patients was more effective than the Mayo regimen of 5-FU and LV. More large scale clinical studies are warranted to evaluate the efficacy of additional INF therapy in colorectal cancer patients.
