A case of cystic lymphangioma of the mesentery with severe and persistent abdominal pain in a 22-year-old man is presented. The cyst was filled with chylous fluid. Microscopically, numerous nerve bundles were incorporated within the lymphangiomatous walls, and some protruded into the lumen. The above findings lead to a suggestion that mesenteric lymphangioma may differ from those in the other sites by its abundance of incorporation of nerve bundles into the lymphangiomatous walls, and that increase of tumor size by intracystic accumulation of chylous fluid may subsequently result in increase of intraluminal pressure to compress the nerve bundles with which abdominal pain is much enhanced.

BACKGROUND: Out-of-pocket health expenditures defined as the charges for services not covered by health insurance have received only sporadic attention. The purpose of this study was to determine the impact of sociodemographic and health characteristics on out-of-pocket health expenditures. METHODS: We used data from the 2001 National Public Health and Nutrition Survey, a nationally representative survey of community-dwelling individuals. The final sample size for this analysis was 61 individuals with age 20 and older cancer patients in Korea. Using a multiple linear regression model to control for differences in sociodemographics, self-reported health status, hospital length of stay, time since perception, and insurance status, the out-of-pocket health expenditures were estimated. RESULTS: Mean monthly out-of-pocket health expenditures were 399,300 won. The highest mean out-of-pocket health expenditures were paid by those with lung cancer, 820,000 won. In the regression analysis, insurance status, resident area, hospital length of stay, and time since perception were statistically significant determinants. Thus, those with higher hospital days, National Health Insurance, metropolitan, and more than 1 year of time since perception experienced higher economic burden. CONCLUSIONS: Policymakers should consider out-of-pocket health expenditure difference by diverse characteristics.

To evaluate the normal development of the paranasal sinuses in children with CT, authors prospectively studied with brain CT scans of 260 children without known sinus diseases, ranging in age from 7 days to 16 years. Maximal anteroposterior and transverse diameters(mm) and maximal cross-sectional area(mm2) of both sides of the maxillary sinus were measured with the aid of computer device. As to the ethmoidal and sphenoidal sinuses, we simply documented the presence of the aplastic ethmoidal sinus and calculated the age-incidence of the sphenoidal sinus pneumatization, respectively. There noted three phases in the development of the maxillary sinus. The anteroposterior and transverse diameters of the maxillay sinus increased nearly in parallel. The former was always greater than the latter. In no cases was the ethmoidal sinus aplastic and almost all sinuses were pneumatized even in infants as early as 7 days old. CT identified the conchal pattern of sphenoidal sinus pneumatization in infants as early as 11 days old. Sphenoidal sinus pueumatization was seen in 38% of the children under the age of 1 year, 82% of the children between the age of 1 and 2 years, and almost all children older than 2 years. The anteroposterior and transverse diameters of the maxillary sinus seem to reach the adult size by 8 years of age, and the conchal pattern of sphenoidal sinus pneumatization can be recognized earlier with CT than on the plain radiographs.

BACKGROUND: The maximal removal rate of indocyanine green (ICG Rmax), which has been used as a useful indicator of quantitative assessment of the hepatic function, has some disadvantages such as high cost, requirement of multiple sampling, and long turn-around time. This study was designed to clarify that the measurement of the lidocaine metabolite, monoethylglycinekylidide (MEGX) test, can replace the ICG Rmax. And in healthy adults, MEGX forma pion was measured and compared according to methods of measurement and serf. METHOD: In 18 patients to whom ICG Rmax test was requested, ICG Rmax test was carried out at two doses of 0.5 mg/kg and 5 mg/kg and MEGX formation after 15 minute of 1 mg/kg lidocaine Injection was measured by fluorescence polarization immunoassay (FPIA) method. The correlation between them was analyzed, To 25 healthy volunteers included in this study as normal control, lidocaine was given intravenously at, a dose of 1 mg/kg and MEGX forma pion was measured IS and 30 minute later (MEGX15, MEGX30) using both high performance liquid chromatography (HPLC) and FPIA methods. RESULT: Patient group resealed significant correlation between ICG Rmax and MEGX15 (r=0.7674, p<0.001) and also between ICG Rl5 and MEGX15 (r=0.5612, p=0.008). There was significant difference between MEGX15 of 9 patients with chronic liver diseases and those of normal controls (22.24+/- 13.18 and 35.40+/- 14.43 ng/mL, respectively) (p=0.01). In normal controls, the correlation between methods was significant (p=0.001) and the values measured by FPIA method was significantly higher than that by HPLG (p(0.001). Of the normal controls, male group had higher MEGX15 values than female group in both methods (in HPLC method 33.89+/-15.95 and 22.53+/- 8.36, and in FPIA method 41.48+/-16.61 and 28.81+/-7.88 ng/mL, respectively), and in female group MEGX30 values was significantly elevated compared to MEGX15 (p<0.001). CONCLUSION: Inferred from the fact that the correlation between ICG Rmax and MEGX was good, MEGX test can be considered a replacement for ICG Rmax. In healthy adults, it is considered that there is serf-related difference In the rate of lidocaine metabolism so we should pay attention to it in interpreting the MEGX results.

Cholesteatoma of the middle ear and mastoid sometimes destroys the posterior wall of the external auditory canal(EAC), and this phenomenon is termed as "automastoidectomy". During the past two years the authors reviewed the CT features of automastoidectomy in eight patients with middle ear cholesteatoma. There was a variable amount of the cholesteatomatous mass or debris within the mastoid cavity in all patients, of whom air collection was found in four. Interestingly, the site and pattern of the erosion of the EAC were nearly, identical between patients with air in the mastoid cavity and those without it . Air in the mastiod cavity was the only clue of the expulsion of the cholesteatoma. So, we think that the expulsion of the cholesteatoma might be predicted when the erosion of the EAC is present in patients with cholesteatoma in the mastoid cavity. CT clearly depicted associated complications caused by the cholesteatoma, such as ossicular destruction (n=8), the eroion of the facial nerve canal (n=2), the erosion of the lateral semicircular canal (n=2), the erosion of the tegmen (n=1), the erosion of the sigmoid sinus plate(n=1), the erosion of the superior esmicircular canal (n=1), and the erosion of the vestibule (n=1). Although much of the natural history of the middle ear cholesteatoma still remains to be determined, we think that careful evaluation of one type of possible progression of the disease will help us understand its clinical course. Moreover, our findings strongly support the use of CT for evaluation of "automustetomy" seen in many cases of cholesteatoma.es of cholesteatoma.

Primary hyperparathyroicism is a state of hypersecretion of PTH by the parathyroid. The etiology has not been established. The three possible etiologies of piimary hyperparathyroidism and incidences are adencena(83%), hyperplasia(15%), and carcinoma(1~2%). Parathyroid carcinoma usually presents in the fourth decades. The hallmark preoperative signs are hypercalcemia(serum calcium 15mg/dl). Palpable neck mass and bane and renal disease. Patients may present with multiple signs and syrnptoms, including recurrent nephrolithiasis, peptic ulcers, mental change, less frequently, extensive bone resorption. However, with greater awareness of the disease and wider use of screening tests, including blood calcium determinations, the diagnosis is frequently made in patients who have no symptoms and minimal, if any, signs of the disease ather than hypercalcemia and elevated levels of parathyroid Hormone. An 38-years-old woman was admitted to the hospital due to pain on the left knee joint. We experienced full-brown symptom pertaining to hyperpara- thyroidism. Thus we report a case herein and also discuss clinical anifestation, histologic features and treatment.
