Consideration of the nutritional status of patients with acute respiratory failure and mechanical ventilation is important for effective patient assessment and management. Patients with acute respiratory failure are at a high risk for developing malnutrition. High glucose intakes given during the administration of total parenteral nutrition (TPN) have been demonstrated to increase CO2 production. The workload imposed by the high CO2 production may precipitate respiratory distress in patients experiencing compromised pulmonary function. The authors report a case of successful weaning from mechanical ventilation in patient with post-operative ARDS by proper nutritional support and by changing the proportion of calories derived from carbohydrates and fats. Substitution of fat calories for carbohydrate in TNA solutions can reduce CO2 production and help wean patients from mechanical ventilation. Conclusively, the TNA (total nutrients admixture) system is more beneficial to patients with acute respiratory failure due to less CO2 production and surfactant production than TPN. For patients with hypercapnia, providing 25% to 30% of calories as carbohydrate and 50% to 55% of calories from fat may be beneficial.

Although rare, renal arteriovenous fistulas have been discovered with increasing frequency since they were first described by Varela in 1923. Arteriovenous fistulas are classified as either congenital or acquired. The diagnosis of this condition is usually made by use of renal angiograms. In case of hematuria and/or hypertension either intra-arterial embolization or surgical excision and clipping of the arterial branch can be done. Intra-arterial superselective embolization seems to cause less functional loss of the renal parenchyme, whereas excision often leads to heminephrectomy or even total nephrectomy. Herein, we describe a case treated successfully in recurred renal A-V fistula after transcatheter embolization by Gianturco steel coil and reviewed the literature of renal A-V fistulas.

PURPOSE: Various factors have been cited in the morbidity of small bowel resections, but their clinical importance is uncertain. We wanted to know what were the significant risk factors elevating the morbidity and how to reduce the morbidity of small bowel resections effectively. METHODS: A retrospective study was done for 107 patients who had undergone small bowel resections from Jan. 1992 to Jul. 1999. The patients were evaluated based on sex and age, the cause and site of resection, the presence of previous abdominal operations, the morbidity, the mortality, and the cause of death in order to determine their clinical significance for small bowel resections. Also the differences of morbidity were analyzed according to the risk factors of old age, pre-op hypotension and hypoalbuminemia, the cause of resection, emergency operation, the presence of a previous abdominal operation, the length of the resection, the presence of associated chronic illness, and spillage of the intestinal content. RESULTS: Complications after small bowel resections occurred in 41 cases (38.3%). The morbidity was significantly increased in the cases with associated chronic illness and spillage of intestinal content by perforation combined with strangulation (p<0.05). Factors such as old age, hypotension, hypoalbuminemia, cause of resection, emergency operation, the length of the resection and spillage of intestinal contents by simple perforation elevated the morbidity, but this result is not statistically significant (0.05
0.5). CONCLUSIONS: We concluded that intensive peri-operative care, a rapid and precise operative technique, and the surgeon's efforts can decrease the morbidity and the mortality after small bowel resections. The selection of the high risk patients should be done based on the surgeon's knowledge of the risk factors including associated chronic illness, and cumulative data obtained by using instituted surveillance for morbidity.

Gymnopilus spectabilis, a hallucinogenic mushroom belonging to the family Cortinariaceae, is found growing in dense clusters on stumps and logs of hardwoods and conifers. It contains the hallucinogenic alkaloid psilocybin and its strongly bitter taste makes it undesirable as an edible. In an effort to identify chemical constituents of Korean native wild mushrooms, 4,6-decadiyne-1,3,8-triol (1), ergosta-4,6,8(14), 22-tetraen-3-one (2), bisnoryangonin (3), and hispidin (4) were isolated from the methanolic extract of the fruiting bodies of G. spectabilis. Their structures were assigned on the basis of various spectroscopic studies. Compounds 3 and 4 displayed significant scavenging activity against the ABTS radical cation, DPPH radical, and superoxide radical anion, while 1 and 2 exhibited no antioxidant activity.

OBJECTIVE: The purpose of this study was to evaluate the ultrasonographic (US) findings in the shoulder impingement syndrome and to correlate them with the Hawkins and Kennedy's clinical stages. METHOD: 41 patients with suspected shoulder impingement syndrome were evaluated. All patients were divided into 3 clinical groups according to Hawkins and Kennedy and US examination was done in each group. RESULTS: US findings were as follows. In stage I, there were 3 normal findings, 5 tendinitis of the rotator cuff (RC), 2 partial thickness tear of RC, and 0 full thickness tear of RC. In stage II, 6 normal findings, 13 tendinitis of RC, 3 partial thickness tear of RC and 2 full thickness tear of RC. In stage III, 0 normal findings, 1 tendinitids of RC, 1 partial thickness tear of RC, and 5 full thickness tear of RC. The most common findings in the tendinits of RC were tendon thickness, focal hypoechogenicity and calcification. In partial thickness tear of RC, focal hypoechogenicity and impingement in abduction were most common findings. In full thickness tear of RC, the irregular humeral head surface and the biceps tendon effusion were most common findings CONCLUSION: The ultrasonography is a valuable means of evaluating the shoulder impingement syndrome and its findings have good correlation with clinical stages

PURPOSE: We evaluated the effect of early chemoradiotherapy on the treatment of patients with limited stage small cell lung cancer (LS-SCLC). MATERIALS AND METHODS: Between January 2006 and December 2011, thirty-one patients with histologically proven LS-SCLC who were treated with two cycles of chemotherapy followed by concurrent chemoradiotherapy and consolidation chemotherapy were retrospectively analyzed. The chemotherapy regimen was composed of etoposide and cisplatin. Thoracic radiotherapy consisted of 50 to 60 Gy (median, 54 Gy) given in 5 to 6.5 weeks. RESULTS: The follow-up period ranged from 5 to 53 months (median, 22 months). After chemoradiotherapy, 35.5% of the patients (11 patients) showed complete response, 61.3% (19 patients) showed partial response, 3.2% (one patient) showed progressive disease, resulting in an overall response rate of 96.8% (30 patients). The 1-, 2-, and 3-year overall survival (OS) rates were 66.5%, 41.0%, and 28.1%, respectively, with a median OS of 21.3 months. The 1-, 2-, and 3-year progression free survival (PFS) rates were 49.8%, 22.8%, and 13.7%, respectively, with median PFS of 12 months. The patterns of failure were: locoregional recurrences in 29.0% (nine patients), distant metastasis in 9.7% (three patients), and both locoregional and distant metastasis in 9.7% (three patients). Grade 3 or 4 toxicities of leukopenia, anemia, and thrombocytopenia were observed in 32.2%, 29.0%, and 25.8%, respectively. Grade 3 radiation esophagitis and radiation pneumonitis were shown in 12.9% and 6.4%, respectively. CONCLUSION: We conclude that early chemoradiotherapy for LS-SCLC provides feasible and acceptable local control and safety.

The histological distinction between benign and malignant phyllodes tumors (PT) is often difficult and arbitrary. We analyzed clinical, histological features and expressions of Ki-67 and p53 using immunohistochemistry and estimate its significance in assessing the grade of malignancy and in predicting the clinical behavior of these tumors on 20 cases of PT of the breast (11 benign, 3 low-grade malignancy and 6 high-grade malignancy). Statistically significant differences between benign, low-grade malignant, and high-grade malignant PT by size of tumor, cellular atypism, stromal cellularity, margin of tumor, and number of mitotic figures. The mean labeling index (LI) of Ki-67 in high-grade malignant PT (9.6+/-9.6) was three-fold higher than that in benign PT (2.7+/-2.2), but this difference was not statistically significant (P=0.074). None of the benign PT were positive for p53, whereas 2 of 3 low-grade malignant and 3 of 6 high-grade malignant PT were positive for p53. Statistically significant differences in the pattern of p53 expression existed among the benign, low-grade malignant, and high-grade malignant lesions (P=0.018). Ki-67 LI and p53 expression were associated with numbers of mitotic figure, but were not associated with metastasis (P=0.546 and 0.216). Increased p53 immunoreactivity is present in high-grade and low-grade malignant PTs in contrast to benign PTs, and malignant PT had a higher Ki-67 LI than benign PT. Thus, p53 and Ki-67 expression may assist in distinguishing benign from malignant PT in diagnostically difficult cases.

PURPOSE: Multiple clinical, biological, and pathologic factors correlate with the outcomes in patients with invasive breast cancer. The utility of a peritumoral vascular invasion (PVI) as an additional prognostic indicator has been poorly defined. The aim of this study was to determine if the presence or absence of PVI can be used to help assess the survival and recurrence. METHODS: An invasion of the vascular space (lymphatic and/or blood vessel) by a tumor, as assessed on routine hematoxylin and eosin sections, was investigated in a 146 women with primary operable invasive breast carcinoma. The presence of PVI was compared with the established prognostic factors such as age, tumor size, axillary lymph node involvement, histological grade, hormonal receptor status, and expression of c-erb B2, Ki-67 and p53. Survival analysis was performed using Kaplan-Meier method and log-rank test. RESULTS: PVI was found in 35.6% of cases and was significantly associated with an increasing tumor size (P=0.033) and metastatic axillary lymph nodes (P=0.012). The 5 year disease free survival (DFS) and overall survival (OS) were significantly lower in the patients with PVI than without PVI (P=0.0431 and 0.0445, respectively). In multivariate analysis, the axillary lymph node status (P=0.001), the tumor size (P=0.044) and PVI (P=0.050) were significant independent prognostic factors for the DFS. In the node- negative breast cancer group and in the node-positive breast cancer group, the 5 year DFS and OS were lower in the patients with PVI than in those without, but this did not show significant difference. CONCLUSION: Cox multivariate analysis showed that PVI is a strong prognostic factor for patients with operable invasive breast cancer and an independent prognostic factor for a recurrence. A histological assessment of PVI can provide prognostic information on primary operable invasive breast carcinoma and might be helpful in making a clinical decision.

PURPOSE: High resolution ultrasonography has made it possible to detect many non-palpable small nodules in thyroid gland. We investigated the prevalence and clinical features of non-palpable thyroid nodule and carcinoma discovered incidentally at screening ultrasonography in healthy women. METHODS: A retrospective review was undertaken on the previous healthy asymptomatic 1, 714 women where selected to undergo screening ultrasonography for the detection of the presence of non-palpable thyroid nodules from January 2004 to December 2004. The aims of study were to define the prevalence of thyroid nodule and carcinoma in healthy asymptomatic women and to access the extent of disease in patients with malignant nodule by surgery. RESULTS: Of the 1, 714 subject, thyroid nodule were detected in 822 (48.0%) women with their prevalence increasing with the increasing age of patients. The malignant detection rate based on the USG-guided fine-needle aspiration (USGFNA) results, including both suspicious and malignant groups, was 2.8% (48/1, 714) of all subjects. 38 of 50 patients with malignant, suspicious or indeterminate cytology underwent surgery and all of them were confirmed to have papillary carcinoma on histological results. In 38 patients with papillary thyroid carcinoma, the average size of tumors was 0.87+/-0.33 cm, a range of 0.3 to 1.5 cm, multifocal tumors were found in 50% (19/38), bilaterality was found in 44.7% (17/38), extrathyroidal extension was observed in 50.0% (19/38), and regional lymph node metastasis was found in 29.4% (5/17). CONCLUSION: High resolution ultrasonography detected a high percentage (48%) of nonpalpable thyroid nodules. Characteristics of thyroid nodules on ultrasonography can be used to decision of optimal management strategies. Total thyroidectomy with lymph node dissection may be suitable in patients with non-palpable papillary thyroid carcinoma due to its high incidence of extrathyroidal extension, bilaterality and regional lymph node metastasis.

PURPOSE: Among persons sustaining severe burns, burn wound infection may develop into devastating sepsis. The purpose of this study is to validate the risk factors for burn wound infection in order to increase the effectiveness of the early treament of those patients at high risk for burn wound infection. METHODS: We retrospectively evaluated 155 hospitalized burn patients with an affected burn area greater than 20% extent and who underwent wound culture because of clinically suspected wound infection from March 1997 to December 2000. RESULTS: When patient age, cause of burn, total burn surface area (TBSA), full thickness burn area (FTBA), anatomical distribution of burn, dehydration at admission treated as independent variables, TBSA and FTBA were seen to significantly influence the burn wound infection rate (p<0.05). When the length of hospital stay, interval from burn to skin graft, outcome of burn were taken as independent variables, the length of hospital stay and outcome of burn were significantly influenced by burn wound infection (p<0.05). CONCLUSION: The high risk group for wound infection comprises patients with extensive TBSA or FTBA and should be selected early to undergo intensive treatment as follows ; meticulous wound monitoring and aseptic maneuver, early eschar excision and early skin graft, adequate nutritional support, isolation against hospital-acquired infection, judicious antibiotic management based on antimicrobial susceptibility testing and control of emergent antibiotic-resistant bacteria.
