PURPOSE: We performed dynamic MR imaging using GdDTPA to find characteristic enhancement pattern of hepatic hemangioma distinguishing from hepatocellular carcinoma. METHODS AND MATERIALS: 28 hepatic hemangiomas and 10 hepatocellular carcinomas were evaluated. Serial dynamic scans after Gd-DTPA(0.1mmol/kg) intravenous injection were obtained by using 0.5T machine and analyzed contrast-to-noise ratio(CNR) of the lesion and enhancement pattern on each scan. RESULTS: Hepatic hemangiomas had positive CNR from 1-2 minute images, and revealed typical "fill-in phenomenon" on early phase with prolonged enhancement in 26 cases(92.8%), and early homogeneous enhancement with isointensity on delayed phase in 2 cases(7.2%) of small hemangiome~ Hepatocellular carcinomas revealed inhomogeneous enhancement with hypointensity on delayed phase in 10 cases(100%) and 3 cases (30%) of capsular enhancement. CONCLUSION: Hepatic hemangioma can be easily distinguished from hepatocellular carcinoma by using Gd DTPA enhanced dynamic MR imaging according to its typical enhancement pattern of "fill-in phenomenon" and prolonged enhancement.

Subcutaneous granuloma pyogenicum (SGP) is a rare variant of granuloma pyogenicum. In general, it appears as a single subcutaneous nodule with a slight tenderness. We report herein an unusual case of SGP arising from the left palm of an 11-year-old girl. Two mild-tender bean-sized reddish or flesh colored subcutaneous nodules on the lateral border of the left palm, and medial side of 5th left finger, respectively, were noted on physical examination. Histopathologic examination revealed the findings of lobular capillary hemangioma, characterized by localized proliferation of capillary lined by a single endothelial cell layer. Intralesional injection of triamcinolone acetonide (TA) were performed for the treatment. However two new erythematous nodules developed at another area of the left palm, which disappeared without any treatment.

OBJECTIVE: Adult onset Still s disease is an acute systemic inflammatory disorder. There are no pathognomonic symptoms or specific laboratory abnormalities. In recent reports, serum ferritin concentration is increased in active disease phase and decreased after defervescence. Our purpose was to determine the clinical significance of serum ferritin as an indicator for disease activity. METHODS: Seven patients who were diagnosed as adult onset Still s disease at Samsung Medical Center between October 1994 and March 1997, were reviewed. In these patients we checked leukocyte count, ESR, CRP and serum ferritin concentrations at the time of diagnosis and during follow-up periods and recorded febrile events during follow-up periods. RESULTS: At the time of diagnosis and during febrile periods, the concentrations of ferritin were extremely high(927ng/ml to 96,650ng/ml normal 10-290.8 ng/ml). The values were unrelated to other manifestations of the disease or laboratory findings. The ferritin concentrations decreased rapidly after adequate treatment. Eleven febrile reattacks happened in 7 patients. Serum ferritin concentrations were increased in 8 febrile attacks, while leukocyte count, ESR, and CRP were increased in 5, 5, 6 febrile attacks respectively, There were 10 events of increased serum ferritin concentrations in 7 patients during follow-up periods and 8 events were related with fever. The increases of other laboratory tests were similar. CONCLUSIONS: In all patients, serum ferritin concentrations were increased at the time of diagnosis and closely related to fever. During follow-up periods, serum ferritin concentrations are helpful in monitoring disease activity and guiding decisions about treatment.

PURPOSE: Laparoscopic approaches to the anterior abdominal wall are difficult because of the inherent limitations of laparoscopic surgery. METHODS: A 25-year-old young female visited to our hospital with an incidentally-found palpable abdominal mass. Computed tomography revealed a 7-cm round enhancing mass arising from the left posterior rectus sheath. The patient underwent laparoscopic excision of the inner mass arising from the anterior abdominal wall. RESULTS: The operation lasted for 45 minutes and there was no measurable bleeding during the procedure. Pathological assessment revealed that the tumor was a DTF 7.0 cm in size. The patient was discharged on the second postoperative day in good condition, and is currently being followed on a routine basis for surveillance without adjuvant therapy. CONCLUSION: Laparoscopic approach for the anterior abdominal wall tumor could be feasible in select patients. This minimally-invasive approach helps to ensure good cosmetic outcomes and quality of life.

PURPOSE: Minimally invasive central pancreatectomy has rarely performed because of its technical difficulty. Robot system enhances surgical dexterity to perform such complex procedures. METHODS: A 29-year-old woman was admitted with acute cholecystitis and an 1.4 cm enhancing mass was incidentally found at the pancreatic proximal body on computed tomography. Preoperative image studies suggested a neuroendocrine tumor or solid pseudopapillary neoplasm. The patient underwent robotic cholecystectomy and central pancreatectomy with pancreaticojejunostomy. RESULTS: The total operation time was 280 minutes and the estimated amount of intraoperative bleeding was 100 ml. The postoperative recovery was uneventful and she was discharged on the 7(th) postoperative day. Pathologic examination reported a solid pseudopapillary neoplasm. CONCLUSION: The technical difficulties associated with the procedure can be overcome with the help of the wrist-like movement of the robotic instruments, especially for the preservation of splenic vessels and for creating precise anastomoses in narrow spaces.

X-linked myotubular myopathy (XLMTM) is a rare congenital muscle disorder, caused by mutations in the MTM1 gene. Affected male infants present severe hypotonia, and generalized muscle weakness, and the disorder is most often complicated by respiratory failure. Herein, we describe a family with 2 infants with XLMTM which was diagnosed by gene analysis and muscle biopsy. In both cases, histological findings of muscle showed severely hypoplastic muscle fibers with centrally placed nuclei. From the family gene analysis, the Arg486STOP mutation in the MTM1 gene was confirmed.

PUPOSE: Through a survey on an Internet homepage, we conducted research concerning the need of patients and their families for information on gastric cancer. We also assessed their interest in gastric cancer. MATERIALS AND METHODS: We analyzed 619 inquiries presented from June 2002 to September 2003 and 524 replies submitted to a questionnaire survey delivered by the Internet homepage (www.gastriccancer.co.kr) from August to October 2003 to gastric cancer patients and their families. RESULTS: Analysis of Inquiries: The classified inquiries listed in order of frequency are as follows: treatment, prognosis, stages, symptoms, pathophysiology, diagnostic modalities, favorable food, etiology, follow-up, etc. Among the inquiries about treatment, the most frequent subgroup was about the scope of surgery or perioperative implications. Next came questions concerning chemotherapy. Among the questions from patients yet to be operated, on those about operability and the prognosis were most frequent. Among the patients who had undergone a resection, questions on complications and the corresponding prognosis were most frequent. The concern from patients with inoperable or recurrent cancers was related to terminal care and/or chemotherapy. Analysis of Questionnaires: The respondents acquired information on gastric cancer from the Internet (40%), doctors (32%), the mass media (15%) and acquaintances (13%). Only 6% of the respondents were sufficiently satisfied with the information provided by doctors. Among the respondents, 89.9% were interested in complementing treatment with folk remedies while only 5% were not. CONCLUSION: Patients and their families were eager to get information about gastric cancer. However, many of them found the doctors' information to be insufficient. Our suggestion is that the public health, academic societies, medical institutions, and public organizations should endeavor to provide through an activated Internet network correct information on gastric cancer.

BACKGROUND: Clinical trials have shown that b-adrenergic blocking drugs are effective and well tolerated in patients with mild to moderate congestive heart failure. Carvedilol is a mild b1-selective adrenergic blocking agent with vasodilating properties due to a blocker and antioxidant and anti-proliferative properties. This study assessed the efficacy and safety of carvedilol in patients with moderate to severe congestive heart failure caused by idiopathic dilated cardiomyopathy. METHODS: We enrolled 27 patients with moderate to severe congestive heart failure with a left ventricular ejection fraction of 35% by MUGA scan. Each patient was randomly assigned to either control (n-9) or carvedilol (n-18, target dose 25 mg bid) for 6 months while background therapy with digoxin, diuretics, and ACE inhibitor remained constant. RESULTS: Compared to the control group, patients in the carvedilol group showed significant increase of left ventricular ejection fraction (p<0.05). In addition, patients in the carvedilol group had a tendency to show a decrease in left ventricular end-diastolic dimension and heart rate. Also, the carvedilol group had a greater frequency of symptomatic improvement than the control group. There was neither serious side effects nor hospitalization. CONCLUSION: These finding indicate that carvedilol produces important clinical benefits in patients with moderate to severe heart failure treated with digoxin, diuretics, and ACE inhibitor without serious side effects.

Plastic bronchitis is a rare disease characterized by marked airway obstruction, via the formation of large gelatinous or rigid airway cast. In Korea, there were a few case reports with plastic bronchitis not in adults, but in children. So we report a case of an adult who was diagnosed as plastic bronchitis with eosinophilic casts, with no history of atopic and cardiac disease.
