A 75-year-old woman who underwent a total thyroidectomy for papillary thyroid cancer 7 years previously presented with a palpable neck mass. Computed tomography (CT) showed two metastatic masses on the thyroid bed and another mass that looked benign originating from the esophageal wall. Endoscopic ultrasonography (EUS) showed a hypoechoic mass in the esophageal wall that looked similar to a gastrointestinal stromal tumor. The mass on the esophagus had intense fluorodeoxyglucose (FDG) uptake in positron emission tomography-computed tomography (PET-CT), which suggested the possibility of malignancy. Subsequently, after surgery, the mass in the esophagus was confirmed as a metastasis from the thyroid papillary carcinoma. Here we report this unusual case of papillary thyroid cancer that recurred as an esophageal submucosal tumor.

Mucoceles are common benign cystic lesions of the oral cavity that develop following extravasation or retention of mucous material from the major or minor salivary glands. Mucoceles are usually located in the lower lip (60 to 70% of cases), and the floor of the mouth is only involved in 6 to 15% of cases. Submandibular gland mucocele is extremely rare but should be considered in the differential diagnosis of swelling at the submandibular triangle in young children. We present the rare case of a 16-month-old child who was diagnosed with bilateral submandibular gland mucocele, presenting as serial swellings in both submandibular regions. We removed the cystic mass with the submandibular and sublingual glands to prevent recurrence.

BACKGROUND: Recent studies have suggested that the outcomes of the patients with acute renal failure (ARF) may related to delivered dose of dialysis. In such context, a number of investigators have reported about delivered dose of dialysis and its contribution to outcomes of ARF, using Kt/V. The purpose of the study was to evaluate actual delivered dose of dialysis in intermittent hemodialysis (HD) in critically ill ARF patients, clinical factors contributing delivery of dialysis dose, and relationship of delivered dialysis dose and survival. METHODS: Delivered and prescribed dose of dialysis, presented as Kt/V, were measured in ARF patients intermittent HD in intensive care unit of Inha University Hospital from January 1999, until December 1999, using single pool urea kinetic model. RESULTS: All subjects received intermittent HD of 6.4+/-4.8 times with mean of 225.6+/-40.4 min per session. Overall survival was 55.5%. Prescribed Kt/V in all subjects was 1.24+/-0.39, but actual delivered Kt/ V was 1.08+/-0.17. A mean delivered/prescribed Kt/V ratio was 87.1+/-43%. Duration of HD session (R= -0.547, p=0.019), Cleveland Clinic Foundation Severity Score (R=-0.486, p=0.041), and frequency of hypotensive episodes (R=-0.419, p=0.043) were significantly correlated with delivered/prescribed Kt/V ratio. Delivered dose was under 1.2 in 66.7% of the subjects. Survival rate of these patients was 50.0%, which was lower as compared to 66.6% of the patients with delivered dose over 1.2. Patients with low delivered dose (Kt/V<1.2) showed significantly low prescribed dose and short HD time (p<0.05). Delivered Kt/V was correlated with BUN at initiation of dialysis, HD duration, and prescribed Kt/V (p<0.05). Non-survivors showed significantly low initial serum creatinine, low CCF severity score, high frequency of hypotensive episodes, and less use of heparin (p< 0.05). Prescribed Kt/V was not different between survivors and non-survivor (1.22+/-0.30 vs 1.31+/-0.45), but delivered Kt/V (1.17+/-0.17 vs. 1.04+/-0.17; p<0.05) and delivered/prscribed Kt/V (95.9+/-22.6% vs. 73.9+/-15.6%; p<0.05) were significantly higher in survivors than in non-survivors. CONCLUSION: In ARF patients, the delivery of dialysis was significantly lower than as was expected. Delivered/prescribed Kt/V was about 87% and more than half of the patients received intermittent HD of Kt/V less than 1.2. Better survival was associated with higher delivered dose of dialysis. We need further prospective studies about the causal relationship between delivered dose of dialysis and outcomes in ARF patients.

For developing race-specific anthropometry-based total body water (TBW) equations, we measured TBW using bioelectrical impedance analysis (TBW(BIA)) in 2,943 healthy Korean adults. Among them, 2,223 were used as a reference group. Two equations (TBW(K1) and TBW(K2)) were developed based on age, sex, height, and body weight. The adjusted R2 was 0.908 for TBW(K1) and 0.910 for TBW(K2). The remaining 720 subjects were used for the validation of our results. Watson (TBW(W)) and Hume-Weyers (TBW(H)) formulas were also used. In men, TBW(BIA) showed the highest correlation with TBW(H), followed by TBW(K1), TBW(K2) and TBW(W). TBW(K1) and TBW(K2) showed the lower root mean square errors (RMSE) and mean prediction errors (ME) than TBW(W) and TBW(H). On the Bland-Altman plot, the correlations between the differences and means were smaller for TBW(K2) than for TBW(K1). On the contrary, TBW(BIA) showed the highest correlation with TBW(W), followed by TBW(K2), TBW(K1), and TBW(H) in females. RMSE was smallest in TBW(W), followed by TBW(K2), TBW(K1) and TBW(H). ME was closest to zero for TBW(K2), followed by TBW(K1), TBW(W) and TBW(H). The correlation coefficients between the means and differences were highest in TBW(W), and lowest in TBW(K2). In conclusion, TBW(K2) provides better accuracy with a smaller bias than the TBW(W) or TBW(H) in males. TBW(K2) shows a similar accuracy, but with a smaller bias than TBW(W) in females.

Cushing's syndrome is produced by the hypersecretion of adrenal glucocorticoids and is characterized by moon face, central obesity, disappearance of diurnal variation of plasma cortisol and unsuppressibility of plasma cortisol by low-dose dexamethasone. On the other hand, hyperaldosteronism is produced by the hypersecretion of aldosterone and is characterized by hypertension and hypokalemia. We report a rare case of adrenal adenoma with concurrent hypercortisolism and hyperaldosteronism manifestated with hypertension, cushingoid appearance, left adrenal mass with low-normal plasma potassium. Laparoscopic unilateral tumor excision was performed and hypertension disappeared after the operation.

Efferent loop bezoars rarely occur. However when patients have a history of gastrectomy and gastrojejunal anastomosis, they are sometimes found. Small bowel obstruction by efferent loop bezoar has a mortality rate as high as 30%. Although various endoscopic procedures were reported to remove gastric bezoars, the traditional treatment option of small bowel bezoars is operative management. But as in the cases we describe here, endoscopic procedure may offer an effective alternative for efferent loop bezoars. Bezoars obstructing efferent loop were found in patients with history of gastrectomy and they were removed by endoscopy successfully.

Diabetic muscle infarction (DMI) is a rare complication of long-standing diabetes mellitus. The typical feature of DMI is abrupt onset of thigh pain, tenderness, and swelling and then spontaneous resolution over several months and frequent recurrence. Until 2004, a case of DMI has been reported among end-stage renal disease patients on dialysis in korea. Under-recognition or misdiagnosis (cellulitis, myositis, abscess, hemorrhage, and tumor) by physicians may contribute to the relative rarity of the diagnosis. We report a case of recurrent diabetic muscle infarction in a hemodialysis patient.

BACKGROUND AND OBJECTIVES: Congestive heart failure is one of the most frequent problems in cardiovascular patients. However, very little data concerning this syndrome in Korea was available. The objectives of this study were to evaluate the demographic and clinical characteristics, and the prognostic factors of patients hospitalized with congestive heart failure in Korea. SUBJECTS AND MEHTODS: Six university hospitals, fulfilling the protocol for clinical information of patients with heart failure, were prospectively engaged in this study. One thousand and forty seven patients, admitted between Jan.1. 1998 and Dec. 31. 2000 were enrolled. RESULTS: The cumulative survival rates at 3 and 6 month, and 1 and 2 years were 90.5, 87.5, 82 and 75.9%, respectively. Ischemic heart disease was the most frequent underlying disease (36.7%). Diabetes mellitus (OR : 1.626, 95% CI : 1.156-2.289, p=0.005), previous history of myocardial infarction (OR : 2.044, 95% CI : 1.488-2.808, p<0.0001), atrial fibrillation (OR : 1.516, 95% CI : 1.042-2.206, p=0.02), and cerebrovascular accident (OR : 2.187, 95% CI : 1.366-3.501, p=0.001) were the worse prognostic factors. CONCLUSION: Ischemic heart disease was the major cause of heart failure. The cumulative 1 year survival rate, of the patients of congestive heart failure was 82%. The poor prognostic factors were diabetes, old myocardial infarction, atrial fibrillation and cerebrovascular accident.
