Gallstone ileus is a well-known complication of cholelithiasis, but is relatively rare. Most ectopic gallstones are located in the small bowel; they are rarely found in the stomach and duodenum. We describe the imaging findings of a case of intragastric gallstone, as well as a case in which duodenal obstruction was caused by a large gallstone (Bouveret's syndrome).

To measure the birth registration rate and the validity of birth registration data in rural area, all of the 4,014 married women under 49 years of age who had not been sterilized in Gunwee county of Kyungpook province were followed by Myun health workers for 2 years from April 1, 1985 to March 31, 1987 and 766 births were detected. All of the birth registration records of Myun offices were reviewed on September 30, 1987 and 944 births which occurred within the above mentioned period were found. Actual birth date obtained by follow-up study were compared with the birth date on registration card. Among 766 births detected by follow-up study, 576 births(75.2%) which were reported within 6 months after birth were ascertained on the official registration records and 96 births(12.5%) were not found on the records although mother stated that the birth was registered. The registration rate within legal due date was 61.3% among 576 births detected by follow-up study and also ascertained on the official records. The registration rate within legal due date was lower in mothers under 20 years of age and above 35 years and in mothers who had only primary education. It was decreased as the birth order increased. The registration rate was higher in births occurred from October to March than births occurred from April to September. All of the births of 7 neonatal deaths were not reported. The registered birth date was consistent with the actual birth date in 78.0%. Birth date on record was earlier than the actual birth date in 6.8% and later in 15.3%. The consistency rate was lower in mothers above 35 years of age(54.5%), and in infants of 4th birth order and above(56.3%). The rate was increased as the maternal education level increased. The rate of boys was higher than that of girls. A higher percentage(17.4%) of infants born in March was registered with earlier date than the actual birth date and most of these registered birth dates were lunar calendar date. This might be related with the age for entering the primary school. The study findings revealed that the birth registration rate within legal due date and accuracy of report have been increased in recent years, but the infant mortality rate derived from the birth registration seems to be very inaccurate. It is suggested to let the medical personnel who delivered the baby report the birth by mail directly to the current address of parent while infants delivered at home without professional attendant may comply with the present registration system.

PURPOSE: To evaluate the safety and efficacy of a laparoscopic nephroureterectomy in patients with a transitional cell carcinoma of the renal pelvis and ureter. MATERIALS AND METHODS: All patients underwent a nephroureterectomy for an upper tract transitional cell carcinoma. Of these, 23 and 22 underwent a laparoscopic nephroureterectomy (LNU) and open nephroureterectomy (ONU), respectively, between January 2002 and June 2006. After the nephrectomy had been performed, a 5-6cm modified Gibson incision was created to allow dissection of the lower ureter and bladder cuff, and extraction of the intact specimen. A retrospective analysis was performed on the operating time, blood loss, analgesic requirement, ambulation time, interval to resume oral intake, hospital stay, complications and follow-up results for both groups. RESULTS: The LNU was superior to the ONU with regard to the mean operation time; 275 (190-390) versus 258 (180-400) (p=0.259), blood loss; 188 (130-250) versus 488ml (350-750) (p<0.05), ambulation time; 2.5 versus 3.3 days (p<0.05), interval to resume oral intake 2.1 versus 2.8 days (p<0.05), and hospital stay; 8.3 versus 11.1 days (p<0.05). Complications developed in 4 and 5 of the LNU and ONU patients, respectively, but all were resolved with conservative management. The mean follow-up duration of the LNU and ONU groups were 29 versus 14 months, respectively. CONCLUSIONS: Based on our experience, a laparoscopic nephroureterectomy is better tolerated with respect to pain, has less blood loss, shorter hospital stays, ambulation time and time to oral intake. LNU is safe for an upper tract transitional cell carcinoma, and is also an efficacious alternative to open surgery. However, a long-term follow-up will be warranted to ascertain accurate oncologic data.

Lateral eyebrow mass with primary skull lesion are rare in pediatric population. Although epidermoid cyst and dermoid cyst are the most commonly encountered skull lesions in pediatric population, Langerhans cell histiocytosis (LCH) is rarely reported. We report a case of LCH arising from the lateral eyebrow with osteolytic lesion involving the frontal bone. A 5-year-old boy was presented with a hard, fixed mass in his lateral eyebrow. Contrast magnetic resonance imaging revealed inhomogeneous enhancement of the mass with direct invasion of the frontal bone and adjacent dura mater. Under general anesthesia, linear incision at the lateral eyebrow region was made. Intraoperative evaluation revealed hard, fixed and well-defined soft tissue mass. The final extirpated mass was 2.5 x 2.4 cm in size, and was accompanied by a 1 x 1 cm sized defect on the frontal bone with intact dura mater. The surgical wound was closed primarily by a layer-by-layer fashion. Histologic examination was later performed for definite diagnosis. The histologic examination revealed abnormal proliferation of Langerhans cell with granuloma formation. Radionuclide bone scan and positron emission tomography was taken and revealed free of multi-organ involvement. At 3 months after surgery, natural looking contour at the lateral eyebrow region was observed with no tumor recurrence. Differential diagnosis of the hard and fixed mass at the lateral eyebrow region affecting the primary skull lesion from pediatric population includes epidermoid cyst, dermoid cyst and LCH. Generally, brief physical examination with plain X-ray view can be performed for clinical evaluation, but for a definite diagnosis, contrast MRI may be helpful.

OBJECTIVE: The purpose of this study is to ascertain whether magnetic resonance(MR) images taken after ethanol injection or microwave irradiation into feline brain can verify changes within the brain and offer valuable information about the spatial extent of the induced lesion. METHODS: In the ethanol injection experiment, nine male cats were divided into three groups including group I(n =3) treated with 0.1cc ethanol injection, group II(n=3) 0.2cc ethanol, and group III(n=3) 0.3cc ethanol into the feline brains. In the microwave irradiation experiment, twelve male cats were divided into four groups including group I(n=3) irradiated with 30 watt electrical power with 10 sec duration, group II(n=3) same power with 30 sec duration, group III(n=3) irradiated with 60 watt power with 10 sec duration, and group IV irradiated with 60 watt power with 30 sec duration. MR images were obtained in both ethanol injection and microwave irradiation experiments. Pathologic examinations were done after completion of MR imagings. RESULTS: Contrast-enhanced T1-weighted MR images showing nodular or rim enhancement were most reliable in delineating the extent of the necrosis induced by ethanol injection and microwave irradiation. The contrast enhancement corresponded with gliosis in normal brain surrounding the necrotic area and hypervascularity in ongoing necrotic area and adjacent normal brain. There were various enhancement patterns after ethanol injection with reflux of ethanol. In case of microwave irradiation, round or oval enhancements were shown with clear margin. The size of the enhancement was well correlated with the amount of injected ethanol and the amount of electrical power. Application time was not correlated with the size of enhancement in high electrical power group. The feature of the edema after ethanol injection was unpredictable and predictable in case of microwave irradiation. CONCLUSION: It is easy to predict the result in case of microwave irradiation, and the achieved results can be used as basic information in performing these procedures.

Gastric bezoar has been known to occur occasionally in the gastrointestinal tract, as a result of foreign material accumulating in the stomach. Most case have been managed by surgical methods. Currently, the endoscopic mathod is after used for the gastrointestinal disease, and therefore we treated two cases of huge bezoars using the endoscopic polypectomy snare and lithotriptor. Subsequently, we are reporting these cases and have incorporated relevant literature which was reviewed for our report for the subject case.
