Malignant tenosynovial giant cell tumor (TsGCT) is a rare disease that can arise as a recurrent lesion or co-exist with a benign TsGCT lesion. Here we report a rare case of malignant TsGCT in a 73-year-old male with a history of lymphoma. The tumor appeared as a superficial soft-tissue mass in the subcutaneous fat tissue of the left knee.

Background: The present study was to compare the potential impact of remifentanil-based propofol-supplemented anesthesia regimen vs. conventional sevoflurane-sufentanil balanced anesthesia on postoperative recovery of consciousness indicated by c) values in patients undergoing cardiac surgery. Methods: Patients undergoing cardiac surgery were randomly allocated to get the remifentanil-based propofol-supplemented anesthesia employing target-controlled infusion (TCI) of remifentanil and propofol (Group-PR, n = 15) or a balanced-anesthesia employing sevoflurane-inhalation and TCI-sufentanil (Group-C, n = 19). In Group-PR, plasma concentration (Cp) of TCI-remifentanil was fixed at 20 ng/ml, and the effect-site concentration of TCI-propofol was adjusted within 0.8–2.0 μg/ml to maintain BIS value of 40–60. In Group-C, sevoflurane dosage was adjusted within 1–1.5 minimum alveolar concentration to maintain BIS of 40–60, and Cp of TCI-sufentanil was fixed at 0.4 ng/ml. The inter-group difference in the time for achieving postoperative BIS > 80 (T-BIS80) in the intensive care unit was determined as the primary outcome. The inter-group difference in the extubation time was determined as the secondary outcome. Results: T-BIS80, was shorter in Group-PR than Group-C (121.4 ± 64.9 min vs. 182.9 ± 85.1 min, respectively; the difference of means –61.5 min; 95% CI –115.7 to –7.4 min; effect size 0.812; P = 0.027). The extubation time was shorter in Group-PR than in Group-C (434.7 ± 131.3 min vs. 946.6 ± 393.3 min, respectively, P < 0.001). Conclusions Compared with the conventional sevoflurane-sufentanil balanced anesthesia, the remifentanil-based propofol-supplemented anesthesia showed significantly faster postoperative conscious recovery in patients undergoing cardiac surgery.

Radiography, ultrasonography with hydrogram, and contrast studies using radiopaque markers were applied to evaluate alimentary lymphoma in two cats. The hydrogram facilitated the differentiation of pseudo-thickening from true wall thickening, and enabled an evaluation of wall layering and lymph nodes. In case 1, mechanical obstruction of the duodenum was confirmed with barium-impregnated polyethylene spheres (BIPS), a radiopaque marker; however, results obtained in case 2 were not as definitive. We expect that hydrograms and BIPS can be used as valuable alternative methods to evaluate the gastrointestinal (GI) tract although further studies in cases involving GI tumors are needed.

We experienced one fatal case of biliary cast syndrome after cadaveric liver transplantation involving both intrahepatic ducts. A 58-year-old man underwent cadaveric liver transplantation because of hepatitis B virus related liver cirrhosis and concomitant hepatocellular carcinoma. Five weeks after the liver transplantation, postoperative course was complicated by development of acute cholangitis. Subsequent endoscopic retrograde cholangiography revealed diffuse intrahepatic bile duct strictures without filling defects. Percutaneous liver biopsy, which was done to exclude rejection, revealed biliary cast. Successful endoscopic removal was precluded due to its diffuse involvement. Because of the deterioration of patient's condition by refractory biliary obstruction and cholangitis, retransplantation from cadaveric donor was performed. Debridement of the biliary tree after graft removal yielded a near-complete cast of the intrahepatic ductal system. Biliary cast syndrome should be suspected when jaundice or cholangitis is associated with dilated ducts on abdominal imaging studies in cadaveric liver transplantation recipients. Initial therapeutic options include removal of biliary cast after endoscopic or percutaneous cholangiography. Although endoscopic retrieval of biliary cast by endoscopic retrograde cholangiopancreatography could be employed as a first-line management, other modalities such as endoscopic nasobiliary drainage, percutaneous transhepatic drainage, or retransplantation should be considered when complete removal is not feasible and the condition of the recipient deteriorates.

Drug-induced sleep endoscopy (DISE) is used to identify areas of upper airway obstruction, which occurs when patients with obstructive sleep apnea (OSA) snore. DISE enables effective diagnosis and appropriate treatment of the obstruction site. Among surgical treatment methods for OSA, maxillomandibular advancement surgery (MMA) is performed to move a jaw forward; the surgery has a high success rate for OSA treatment. In DISE, anesthetics such as propofol and midazolam must be administered to induce snoring while the patient is deeply sedated for an accurate diagnosis to be made. When inducing deep sedation in a patient with OSA, airway obstruction may increase, causing oxygen saturation to drop; airway interventions are necessary in such cases. Effective DISE and MMA surgery can be performed by administering propofol through target-controlled infusion while monitoring the bispectral index (BIS).

BACKGROUND/AIMS: Endoscopic papillectomy is reported to be relatively safe and reliable for complete resection of benign tumors of the major duodenal papilla. We evaluated methods and treatment outcome of the patients who have undergone endoscopic papillectomy. METHODS: Medical records of 22 consecutive patients with tumor of the major duodenal papilla (10 women, 12 men; mean age 55.8+/-2.8 yrs) who have undergone endoscopic papillectomy were reviewed retrospectively. Endoscopic papillectomy was defined the successful when complete excision of the tumor was achieved. RESULTS: Mean duration of follow-up was 8.4+/-2.4 months (range 1-43 months). Endoscopic papillectomy was successful in 16 patients (72.7%), but incomplete resection occurred in 6 patients. Only one patient showed recurrence. Histopathologic evaluation after endoscopic papillectomy revealed adenoma (n=11, 50%), high-grade dysplasia (n=3, 13.6%), adenocarcinoma (n=2, 9.1%), carcinoid (n=1), chronic inflammation (n=3, 13.6%), papillary adenomatous hyperplasia (n=1), and cavernous lymphangioma (n=1). The mean size of the resected lesions was 10.3+/-1.2 mm (range 2-20 mm). There was no factor which could predict the endoscopic success statistically. A pancreatic duct stent was placed in 11 patients (50.0%) and was removed after 3 to 39 days. There were 8 (36.8%) procedure-related complications: bleeding (n=4), papillary stenosis (n=1), perforation (n=1), cholangitis (n=1), and asymptomatic liver function abnormality (n=1). There was no pancreatitis or mortality. All the complications resolved with conservative management. CONCLUSIONS: Endoscopic papillectomy in selected patients seemed to be highly successful and safe. Longer follow-up is needed to assess the long-term efficacy.

Inflammatory linear verrucous epidermal nevi (ILVEN) were first described in the literature, in 1971, by Altman and Mehregan. Most cases were reported as solitary lesions. In contrast, systematized ILVEN, involving wide areas of the integument, has only rarely been reported. A variety of treatment modalities has been reported, ranging from topical medications, such as potent corticosteroids or tretinoin 0.1% to variable procedures, including CO2 and pulsed dye laser, cryotherapy, and surgical excision. However, multifocal skin lesion is more difficult to treat. An 8-year old boy was presented with an extensive thick scaly plaques and patches, affecting the trunk and the four extremities sparing face. It developed when he was 3 years old, and he complained pruritus. On physical examination, linear, or whirl-like scaly plaques were seen, along with Blaschko lines. Pathologic finding was in accordance to ILVEN. We treated him with topical calcipotriol, tacrolimus and systemic acitretin. After 8 months, the lesion and symptoms improved.

BACKGROUND: The aim of this study was to observe clinical outcomes of the mother and her infant who were possibly exposed to high blood glucose at least 2-3 months in the early and midterm pregnancy by checking gestational weeks (GW) and the first HbA1c level at initial diagnosis of gestational diabetes (GDM). METHODS: A total of 107 GDM patients and their newborns were subject of this study. GDM patients were newly diagnosed at the Holy Family Hospital of Catholic University from January 2003 until December 2007 and continuously managed in the diabetes center. Patients medical records were retrospectively reviewed to evaluate GW and HbA1c level at the time of diagnosis, and clinical outcomes of mother and newborn baby. RESULTS: The proportion of subjects who had been diagnosed of having GDM according to GW was 7.5%, in less than 24th week of pregnancy; 55.1% in the 24-28th week; 28.0% in the 29-32nd week; and 9.4% 33rd week or more. There were 39 out of 107 subjects (36.4%) with HbA1c levels > or =6.5% and 26 out of 39 subjects (24.3%) with HbA1c levels > or =7.0%. In clinical outcomes of newborn by HbA1c levels, the frequency of delivery of large for gestational age (LGA) infant was higher in mothers diagnosed with GDM after 29th week of pregnancy or with HbA1c levels 7.0% or more (P<0.001). CONCLUSIONS: If the screening test for gestational DM was delayed, HbA1c level and the risk for LGA seemed to be higher, so it may be necessary to screen GDM no later than 24th week of pregnancy.
