BACKGROUND: Pressure support ventilation(PSV) is a new form of mechanical ventilatory support that assists spontaneous inspiratory effort of an intubated patient with a clinician-selected amount of positive airway pressure. Low level pressure support during inspiration can overcome the resistive component of inspiratory work imposed by ah endotracheal tube. However the clinical efficacy of PSV as a weaning method has not been established yet. Object : The aim of study was to evaluate the efficacy of PSV when it is added to intermittent mandatory ventilation (IMV) in facilitating weaning process compared to IMV mode alone. METHOD: When the subject patients became clinically stable with their arterial blood gas analysis in acceptable range, they underwent weaning process either by IMV alone or by IMV plus PSV. The level of pressure support was held constant through the weaning period. For the patients who required mechanical ventilation for less than 72hr, 2h weaning trial was performed with IMV rate starting from 6/min. For the patients who required mechanical ventilation more than 72 hr, 7 hr weaning retrial was performed with IMV rate starting from 8/min. For the patients who failed three consecutive trials of weaning, retrial of weaning was attempted over 3 days with IMV rate starting from 8/min. Clinical characteristics, APACHE II score and nutritional status were compared. For all patients, heart rate, mean blood pressure and respiratory rate were mornitored for 48 hrs after weaning trial started. RESULTS: The total number of weaning trial was 37 in 23 patients(18 by IMV, 19 by IMV+PSV). Total ventilation time, APACHE II score and nutritional status were not statistically different between the two groups. The weaning success rate were not statistically different(38.3% by IMV, 42.1% by IMV+PSV) and the changes of mean blood pressure, heart rate, respiratory rate during first 48 hours were not different between the two groups. CONCLUSION: Low level PSV when added to IMV for weaning trial does not seem to improve the success rate of weaning from mechanical ventilation. PSV at 10cm H2O did not induce significant physiologic changes during weaning process.

PURPOSE: One of the most important adverse effects of long-term cyclosporine therapy is nephrotoxicity, the morphologic changes of which include interstitial fibrosis and arteriolar hyalinization. Recently, several authors have shown that osteopontin plays an important role in the development of interstitial fibrosis by acting as a macrophage chemoattractant and stimulating the production of TGF-beta in experimental cyclosporine nephrotoxicity. However, the relationship between osteopontin and TGF-beta in humans has not been clearly documented so far. We studied the expression of osteopontin and TGF-beta in children with minimal change nephrotic syndrome treated with cyclosporine to demonstrate whether there is a relationship between cyclosporine toxicity and osteopontin expression as previously shown in animal models. MATERIALS AND METHODS: Nineteen children (15 males and 4 females) were the subject of this study. Renal biopsies had been performed before and after the cyclosporine therapy (mean duration: 15.9 months). In 5 patients, additional biopsies were performed after completing the cyclosporine treatment (mean: 26 months). The expressions of osteopontin and TGF-beta were evaluated by immunohistochemistry in the glomeruli and tubulointerstitium. RESULTS: Osteopontin expression was significantly increased in the glomerular mesangium and tubules after cyclosporine treatment. But there was no statistically significant increase of TGF-beta in the interstitium. There was no significant increase in tubular osteopontin and interstitial TGF-beta expression in those cases developing interstitial fibrosis after cyclosporine treatment compared with cases those not developing interstitial fibrosis. No significant changes in osteopontin or TGF-beta expression were observed in subsequent 5 biopsy samples after discontinuation of cyclosporine compared with the first follow up biopsies. CONCLUSION: These results suggest that osteopontin is a nonspecific marker of renal injury rather than a mediator of interstitial fibrosis in cyclosporine nephrotoxicity of human.

Somatostatinoma is a rare form of neuroendocrine tumor that was first described in 1977. Most tumors have involved the pancreas, and gastrointestinal tract involvement is rare. Somatostatinomas of the ampulla of Vater are extremely rare and present distinct clinical and pathologic differences. Pancreatic somatostatinoma has been associated with a clinical syndrome of dyspepsia, mild diabetes, cholelithiasis, steatorrhea, and hypochlorhydria, but duodenal somatostatinoma, in general, has been clinically silent. A further contrast is that duodenal carcinoid tumors, mainly gastrinoma, tended to be benign, whereas ampullary carcinoid tumors, mainly somatostatinoma, exhibited malignant behavior. Therefore, definite diagnosis is important for treatment and prognosis, and is performed by image study, immunohistochemistry and electron microscopic examination. We report a case of somatostatinoma of the ampulla of Vater in a 51-year-old male. He complained of generalized abdominal pain for a few days. Gastrofiberscopically, a 1.2 cm sized bulging mass was observed on the ampulla of Vater. Radiologically, on abdomen CT, a protruding enhancing mass was revealed in the duodenum. In octreoscan, there was an abnormal focus off increased radiouptake in the infrahepatic area. He underwent a pancreatoduodenectomy. Grossly, the mass was an intraluminary protruding polypoid submucosal mass with focal ulceration in the ampulla of Vater. Histologically, it showed well-differentiated nonpleomorphic tubular cell nest and psammoma bodies. Immunohistochemically, the tumor cells showed a neuroendocrine nature with synaptophysin immunostain and intense staining only for somatostatin.

BACKGROUND: Pressure support(PS) is becomimg a widely accepted method of mechanical ventilation either for total unloading or for partial unloading of respiratory muscle. The aim of the study was to find out if PS exert different effects on respiratory mechanics in synchronized intermittent mandatory ventilation(SIMV) and continuous positive airway pressure (CPAP) modes. METHODS: 5, 10 and 15 cm H2O of PS were sequentially applied in 14 patients(69+/-12 yrs, M:F=9:5) and respiratory rate (RR), tidal volume(VT), work of breathing(WOB), pressure time product(PTP), P(0.1), and T(1)/T(TOT) were measured using the CP-100 pulmonary monitor(Bicore, USA) in SIMV and CPAP modes respectively. RESULTS: 1) Common effects of PS on respiratory mechanics in both CPAP and SIMV modes As the level of PS was increased(0, 5, 10, 15 cm H2O), VT was increased in CPAP mode(0.28+/-0.09, 0.29+/-0.09, 0.31+/-0.11, 0.34+/-0.12 L, respectively, p=0.001), and also in SIMV mode(0.31+/-0.15, 0.32+/-0.09, 0.34+/-0.16, 0.36+/-0.15 L, respectively, p=0.0215). WOB was decreased in CPAP mode(1.40+/-1.02, 1.01+/-0.80, 0.80+/-0.85, 0.68+/-0.76 joule/L, respectively, p=0.0001), and in SIMV mode(0.97+/-0.77, 0.76+/-0.64, 0.57+/-0.55, 0.49+/-0.49 joule/L, respectively, p=0.0001). PTP was also decreased in CPAP mode(300+/-216, 217+/-165, 179+/-187, 122+/-114cm H2O * sec/min, respectively, p=0.0001), and in SIMV mode(218+/-181, 178+/-157, 130+/-147, 108+/-129cm H2O.sec/min, respectively, p=0.0017). 2) Different effects of PS on respiratory mechanics in CPAP and SIMV modes By application of PS (0, 5, 10, 15 cm H2O), RR was not changed in CPAP mode(27.9+/-6.7, 30.0+/-6.6, 26.1+/-9.1, 27.5+/-5.7/min, respectively, p=0.505), but it was decreased in SIMV mode (27.4+/-5.1, 27.8+/-6.5, 27.6+/-6.2, 25.1+/-5.4/min, respectively, p=0.0001). P(0.1) was reduced in CPAP mode(6.2+/-3.5, 4.8+/-2.8, 4.8+/-3.8, 3.9+/-2.5 cm H2O, respectively, p=0.0061), but not in SIMV mode(4.3+/-2.1, 4.0+/-1.8, 3.5+/-1.6, 3.5+/-1.9 cm H2O, respectively, p=0.054). T(1)/T(TOT) was decreased in CPAP mode(0.40+/-0.05, 0.39+/-0.04, 0.37+/-0.04, 0.35+/-0.04, respectively, p=0.0004), but not in SIMV mode(0.40+/-0.08, 0.35+/-0.07, 0.38+/-0.10, 0.37+/-0.10, respectively, p=0.287). 3) Comparison of respiratory mechanics between CPAP+PS and SIMV alone at same tidal volume. The tidal volume in CPAP+PS 10 cm H2O was comparable to that of SIMV alone. Under this condition, the RR(26.1+/-9.1, 27.4+/-5.1/min, respectively, p=0.516), WOB(0.80+/-0.85, 0.97+0.77 joule/L, respectively, p=0.485), P0.1(3.9+/-2.5, 4.3+/-2.1 cm H2O, respectively, p=0.481) were not different between the two methods, but PTP(179+/-187, 218+/-181 cmH2O.sec/min, respectively, p=0.042) and T(1)/T(TOT)(0.37+/-0.04, 0.40+/-0.08, respectively, p=0.026) were significantly lower in CPAP+PS than in SIMV alone. CONCLUSION: PS up to 15 cm H2O increased tidal volume, decreased work of breathing and pressure time product in both SIMV and CPAP modes. PS decreased respiration rate in SIMV mode but not in CPAP mode, while it reduced central respiratory drive(P(0.1)) and shortened duty cycle (T(1)/T(TOT)) in CPAP mode but not in SIMV mode. By 10 cm H2O of PS in CPAP mode, same tidal volume was obtained as in SIMV mode, and both methods were comparable in respect to RR, WOB, P(0.1), but CPAP+PS was superior in respect to the efficiency of the respiratory muscle work (PTP) and duty cycle(T(1)/T(TOT)).

Background: We prospectively evaluated the applicability and effect of noninvasive ventilation (NIV) in acute respiratory failure and tried to find out the parameters that could predict successful application of NIV. Methods: Twenty-six out of 106 patients with either acute ventilatory failure (VF: PaCO2> 43 mm Hg with pH <7.35) or oxygenation failure (OF: PaO2/FIO2 < 300 mm Hg with pH> or = 7.35) requiring mechanical ventilation were managed by NIV (CPAP + pressure support, or BiPAP) with face mask. Eleven out of 19 cases with VF (57.9%) (M: F=7: 4, 55.4 +/-14.6 yrs) and 15 out of 87 cases with OF (17.2%) (M: F= 12: 3, 50.6+/-15.6 yrs) were suitable for NIV. Respiratory rates, arterial blood gases and success rate of NIV were analyzed in each group. Results: 81.8% (9/11) of VF and 40% (6/15) of OF were successfully managed on NIV and were weaned from mechanical ventilator without resorting to endotracheal intubation. Complications were noted in 2 cases (nasal skin necrosis 1, gaseous gastric distension 1). In NIV for ventilatory failure, the respiration rate was significantly decreased at 12 hour of NIV (34+/-9 /min pre-NIV, 26+/-6 /min at 12 hour of NIV, p=0.045), while PaCO2 (87.3+/-20.6 mm Hg pre-NIV, 81.2+/-9.1 mm Hg at 24 hour of NIV) and pH (7.26 +/-0.04, 7.32 +/-0.02, respectively, p< 0.05) were both significantly decreased at 24 hour of NIV. In NIV for oxygenation failure, PaO2 were not different between the successful and the failed cases at pre-NIV and till 12 hours after NTV. The PaO2/FIO2 ratio, however, significantly improved at 0.5 hour of NIV in successful cases and were maintained at around 200 mm Hg (n=6: at baseline, 0.5h, 6h, 12h: 120.0+/-19.6, 218.9+/-98.3, 191.3+/-55.2, 232.8+/-17.6 mm Hg, respectively, p=0.0211), but it did not rise in the failed cases (n=9: 127.9+/-63.0, 116.8+/-24.4, 100.6 +/-34.6, 129.8+/-50.3 mm Hg, respectively, p=0.5319). Conclusion: From the above results we conclude that NIV is effective for hypercapnic respiratory failure and its success was heralded by reduction of respiration rate before the reduction in PaCO2 level. In hypoxic respiratory failure, NIV is much less effective, and the immediate improvement of PaO2/FIO2 ratio at 0.5h after application is thought to be a predictor of successful NIV.

Inflammatory bowel disease, such as ulcerative colitis and Crohn's disease, has a potential risk of developing into colorectal cancer. However, there is little relationship between intestinal tuberculosis and colon cancer because intestinal tuberculosis is a curable disease and has a relatively short disease course. Nevertheless, there have been a few case reports of intestinal tuberculosis associated with colon cancer. There was a case report in which the carcinoma facilitated entry of tubercle bacilli with development of a secondary infection, and ulcerative lesions of tuberculosis may be precursors of carcinomas. We experienced a 77-year-old woman who had intestinal tuberculosis combined with ascending colon cancer. She visited our hospital because of abdominal pain and constipation. Colonoscopy showed a luminal obstruction mass in the ascending colon. Histologic examination revealed an adenocarcinoma. After surgery, the surgical specimen disclosed an adenocarcinoma in the cecum and ascending colon and intestinal tuberculosis around the cancer site of the cecum. Herein, we report a rare case of colon cancer co-existing with colonic tuberculosis with a review of the literature.

BACKGROUND: Tracheal Gas Insufflation (TGI) is one of the newer ancillary measures in mechanical ventilation employed to enhance carbon dioxide elimination.7G1 exerts its effect through reduction of deadspace ventilation, but the factors determining its effect are not well studied yet. METHOD: The subjects were seven mechanically-ventilated patients (58.8+/-10.6 yrs) who showed increased Physiologic deadspace greater than 60%. After 30 min of stabilization with 100% oxygen on pressure control ventilation, continuous flow TGI was administered via the insufflation lumen of Hi-Lo Jet Tracheal Tube (Mallincrodt, USA) for 15 min at 3 L/min and 5 L/min each. RESULTS: PaCO2 was decreased (51.4+/-17.6 at baseline,49.1+/-18.9 at TGI 3 L/min, 45.0+/- 14.9 mmHg at TGI 5 L/min, p=0.050), and pH was increased (7.37+/-0.12, 7.38+/-0.13, 7.39+/-0.12, respectively, p=0.037) while mixed expired CO2 (PECO2) was not changed significantly from baseline (p=0.336) by TGI. Physiologic deadspace(Vdphy) was decreased (73.0+/-7.9% at baseline, 69.8+/-10.0% at TGI 3 L/min, and 67.1+/-10.1% at TGI 5 L/mi% p=0.015). AaDO2(p=0.147), Vt(p=0.2140), Pmean(p=0.7788) and mean arterial pressure(p=0.4169) were not changed. The correlation between % maximal decrease of Vdphy were r=0.790 with the ratio of baseline Vdana/vdphy(p=0.035) and r=-0.754 with baseline Vdalv(p=0.050). CONCLUSION: TGI was effective in reducing PaCO2 and deadspace, and the deadspace-reducing effect was best correlated with baseline anatomic/physiologic deadspace ratio.

BACKGROUND: The index which could predict the prognosis of critically ill patients is needed to find out high risk patients and to individualize their treatment. The APACHE III scoring system was established in 1991, but there has been only a few studies concerning its prognostic value. We wanted to know whether the APACHE III scores have prognostic value in discriminating survivors from nonsurvivors in sepsis. METHODS: In 48 patients meeting the Bones criteria for sepsis, we retrospectively surveyed the day 1 (Dl), day 2(D2) and day 3(D3) scores of patients who were admitted to intensive care unit. The scores of the sepsis survivors and nonsurvivors were compared in respect to the Dl score, and also in respect to the changes of the updated D2 and D3 scores. RESULTS: 1) Of the 48 sepsis patients, 21(43.5%) survived and 27(56.5%) died. The nonsurvivors were older(62.7+/-12.6 vs 51.1+/-18.1 yrs), presented with lower mean arterial pressure(56.9+/-26.2 vs 67.7 +/-14.2 mmHg) and showed greater number of multisystem organ failure(1.2+/-0.8 vs 0.2+/-0.4) than the survivors(p <0.05, respectively). There were no significant differences in sex and initial body temperature between the two groups. 2) The Dl score was lower in the survivors (n=21) than in the nonsurvivors (44.1 +/-14.6, 78.5+/- 18.6, p=0.0001). The D2 and D3 scores significantly decreased in the survivors (Dl vs D2, 44.1+/- 14.6: 37.9+/-15.0, p=0.035; D2 vs D3, 37.9+/-15.0: 30.1 +/-9.3, p=0.0001) but showed a tendency to increase in the nonsurvivors (Dl vs D2 (n=21), 78.5+/-18.6: 81.3+/-23.0, p=0.1337; D2 vs D3 (n=11), 68.2+/-19.3: 75.3+/-18.8, p=0.0078). 3) The D1 scores of 12 survivors and 6 nonsurvivors were in the same range of 42~67 (mean D1 score, 53.8+/-10.0 in the survivors, 55.3+/-10.3 in the nonsurvivors). The age, sex, initial body temperature, and mean arterial pressure were not different between the two groups. In this group, however, D2 and D3 was significantly decreased in the survivors(Dl vs D2, 53.3+/-10.0: 43.6+/- 16.4, p=0.0278; D2 vs D3, 43.6+/-16.4: 31.2+/-10.3, p=0.0005), but showed a tendency to increase in the nonsurvivors(Dl vs D2 (n=6), 55.3+/-10.3:66.7+/-13.9, p=0.1562; D2 vs D3 (n=4), 64.0+/- 16.4:74.3+/-18.6, p=0.1250). Among the individual items of the first day APACHE III score, only the score of respiratory rate was capable of discriminating the nonsurvivors from the survivors (5.5 +/-2.9 vs 1.9+/-3.7, p=0.046) in this group. CONCLUSION: In sepsis, nonsurvivors had higher first day APACHE III score and their updated scores on the following days failed to decline but showed a tendency to increase. Survivors, on the other hand, had lower first day score and showed decline in the updated APACHE scores. These results suggest that the first day and daily updated APACHE III scores are useful in predicting the outcome and assessing the response to management in patients with sepsis.

PURPOSE: Idiopathic granulomatous mastitis is a rare benign inflammatory breast disease of an unknown etiology and the optimal treatment remains controversial. The aim of this study is to evaluate the efficacy of surgically complete excision in patients with idiopathic granulomatous mastitis. METHODS: Between March 2005 and November 2008, we treated 14 cases that were diagnosed with idiopathic granulomatous mastitis. Prospectively, we treated the cases with complete surgical excision with or without steroid therapy in all patients. RESULTS: The mean age of the patients was 36 years (range 30 to 53 years). All cases performed were complete excision with or without steroid therapy. The median follow up period was 26 months (range 5 to 50 months) and all cases had no recurrence. 13 patients out of the 14 were satisfied with the cosmesis of the treated breast. CONCLUSION: We conclude that the treatment of choice for idiopathic granulomatous mastitis is surgically complete excision.
