Small cell carcinoma of the gallbladder is a type of neuroendocrine tumor and very rare. We report ultrasound, CT and MR findings of a small cell carcinoma of the gallbladder that was confirmed by pathology. Small cell carcinoma of the gallbladder was seen as a well-defined mass with peripheral rim enhancement in the gallbladder. In spite of the large size of the mass, direct and extensive invasion of the liver was not detected. However, there were many metastatic lymph nodes.

Purpose: To report a case of acute angle-closure attack resulting from hemorrhagic retinal detachment after a double retinal pigment epithelium (RPE) tear in exudative age-related macular degeneration (AMD) with large pigment epithelial detachment (PED).Case summary: A 66-year-old female visited with a complaint of poor vision in left eye, which began 1 month prior. She was diagnosed with exudative AMD with a large PED using optical coherence tomography and indocyanine green angiography. Intravitreal aflibercept injection was performed. The RPE tear occurred at 2 weeks after the intravitreal anti-vascular endothelial growth factor injection for AMD, after which the range of the RPE tear expanded and included the macular area at 4 weeks after the second injection. At 3 months after the third injection, massive submacular hemorrhage occurred; aflibercept injection was repeated. At 3 days after the fourth injection, the patient’s intraocular pressure (IOP) was 60 mmHg, and massive hemorrhagic serous retinal detachment and anterior movement of the lens with total angle closure were observed. Therefore, we performed a sclerotomy; a large amount of dark blood and subretinal fluid was drained. The IOP decreased, and the retinal detachment improved somewhat. The patient was kept under observation for careful monitoring of her condition. Conclusions It is very rare to experience a double RPE rupture after intravitreal anti-vascular endothelial growth factor injection in AMD. We report on our experience and treatment of acute angle-closure attack. The IOP increased due to hemorrhagic retinal detachment after a double RPE tear over the treatment course.

Seborrheic keratosis is one of the most common benign epithelial tumors, especially in elderly patients. Squamous cell carcinoma is the second most common malignant tumor of the skin. Despite the fact that both tumors are common, malignant transformation of seborrheic keratosis rarely occurs. Herein we report a case of squamous cell carcinoma arising in a patient with pre-existing seborrheic keratosis.

PURPOSE: Non-alcoholic fatty liver disease (NAFLD) has been recognized as an important childhood liver disease, especially where the prevalence of childhood obesity is increasing. The purpose of this study is to clarify the usefulness of elevated serum aminotransferase activities and their ratio for predicting the presence of fatty liver and its severity in obese children. METHODS: Forty-four children (M/F 29/15, age 4 to 16 years) with obesity (weight excess>20%) were analyzed retrospectively with medical records based on degree of obesity, bioelectrical impedence, serum aminotransferase activities, lipid profiles and ultrasonography. RESULTS: 1) Ultrasonography was carried out in 34 cases. Elevated serum ALT was found in 89.7% (26/29) of the patients diagnosed as fatty liver by ultrasonography and decreased AST/ALT ratio (<1) was found in 96.6% (28/29). There was a strong correlation between elevated serum ALT (>45 IU/L) or decreased AST/ALT ratio (<1) and the fatty liver in obese children (p<0.05). 2) There was no significant correlation between the serum ALT or AST/ALT ratio and the degree of fatty liver (p>0.05). 3) There was a significant correlation between total cholesterol, triglyceride and fatty liver (p<0.05). CONCLUSION: Serum ALT activity and AST/ALT ratio were useful to predict the presence of fatty liver diagnosed by ultrasonography in obese children, whereas they were not useful to predict the degree of fatty liver. Therefore, to prevent fatty liver progressing to advanced liver disease, it is necessary to manage and monitor the obese children continuously, especially those who have predicting factors of fatty liver.

OBJECTIVE: To evaluate the accuracy and safety of C1-C2 transarticular screw insertion, we retrospectively review surgical records and postoperative radiological findings. METHODS: From January 2001 to October 2003, the C1-C2 transarticular screw fixation and posterior wiring with iliac bone grafts was performed in 16 pateints. 6 patients had rheumatoid arthritis which caused cervical instability, 3 patients had os odontoideum, 3 patients had type 2 odontoid process fracture, 3 patients had traumatic transverse ligament injury and 1 patients who had been managed with C1-C2 wire fixation had psoriatic arthritis. RESULTS: Osseous fusion was documented in 15 patients(93.8%). Only one patient was recorded screw loosening because of postoperative infection. One patient had only one screw placed because of abnormal anatomical structure, one patients was breakage of a Kirschner wire, and one screw was medial location to lateral mass of C1, but clinical results was excellent and radiological instability was not noted. CONCLUSION: The author's experience demonstrates that C1-C2 transarticular screw fixation with wired bone graft is a safe procedure with higher fusion rate but precaution is needed to avoid the neural damage, vertebral artery injury, and hardware failure.

PURPOSE: Rotavirus is one of the most important causes of nosocomial infections among children. The aim of this study is to determine the risk of nosocomial rotavirus infections and to evaluate the effectiveness of breast-feeding and probiotics in the prevention of nosocomial rotavirus infections. METHODS: This study was carried out on admitted children without diarrhea between March 1, 2003 and February 29, 2004. Three hundred ninety patients aged 4 days to 13 years during this study were available. We examined the feces of all children for rotavirus by latex agglutination on admission, during hospital, and after discharge, to see whether they developed diarrhea or not. RESULTS: Nosocomial rotavirus infections was significantly increased with children under 12 months of age(P=0.008). The monthly attack rate was great between December and March(P=0.046). Prolonged hospital stay was associated with an increased attack rate of nosocomial rotavirus infections (P=0.003). The risk of nosocomial rotavirus infections was not associated with the number of roommates and whether or not they were breast-fed or fed on probiotics. CONCLUSION: Nosocomial rotavirus infections are significantly more likely to occur in children under 12 months of age, admitted between December and March, and with prolonged hospital stays. Prompt identification and isolation of children with nosocomial rotavirus infections, even without diarrhea, may decrease rates of nosocomial rotavirus infections.

OBJECTIVES: Benzodiazepines are most often used for the treatment of alcohol withdrawal, but they also may result in several adverse consequencies such as sedation, respiratory depression, cognitive impairment, disinhibition, and abuse. New anticonvulsants, topiramate may have a potential to treat alcohol withdrawal effectively. This study compared the therapeutic responses of a benzodiazepine, lorazepam, and an anticonvulsant, topiramate, for the treatment of alcohol withdrawal. METHODS: Fifty-two hospitalized patients with the diagnosis of DSM-IV Alcohol dependence, after obtaining written informed consent, were randomely divided into the either lorazepam (N=27) or the topiramate (N=25) groups. Subjects were assessed with CIWA-Ar scores at the time of baseline, 1, 3, 5 day after the last alcohol drinking. Lorazepam was given 4 mg divided by 4 on day 1, tapering to 2 mg divided by 2, and topiramate was given fixed single dose of 50 mg a day. RESULTS: There were no significant differences between two groups in demographic or clinical characteristics except marital status and s-ALT level. Two groups had similar ADS scores and baseline withdrawal severity. There were no significant differences by treatment group in CIWA-Ar scores over time (F=0.883, p>0.05). CONCLUSION: Efficacy and safety were not different between the two groups. Therefore our results suggest that topiramate is a promising alternative agent to benzodiazepine for treating alcohol withdrawal.

PURPOSE: To evaluate the role of curative radiotherapy alone in the treatment of uterine cervical carcinomas, by a retrospective analysis with respects to survival and pelvic control, and to find any risk factors of failure MATERIALS AND METHODS: Between Jan. 1990 and Dec. 1995, a total of 187 patients, diagnosed with uterine cervical carcinomas in FIGO stages greater than IA, were treated by curative radiotherapy alone with no chemotherapy. The ages of the patients ranged from 26 to 80 years, with a median of 60 years. The number of patients diagnosed with squamous cell carcinomas were 183 (97.9%). The number of patients with FIGO stage IB1, IB2, IIA, IIB, IIIA, IIIB and IVA were 61 (32.6%), 7 (3.7%), 43 (23.0%), 62 (33.3%), 3 (1.6%), 7 (3.7%) and 4 (2.1%), respectively. External radiotherapy was performed with 6 MV or 10 MV X-rays, with a dose range of 19.8 Gy~ 50.4 Gy (median; 30.6), to whole pelvis. Intracavitary radiation (ICR) was then performed using a high-dose rate remote controlled afterloader with radioisotopes of Co-60 and Cs-137. The fraction size of the ICR was 5 Gy twice a week, and was delivered up to total doses of 10 Gy~ 55 Gy (median; 40). After the ICR, additional pelvic external radiotherapy with midline shielding width of 4 cm was performed with the dose range of 0~30.6 Gy (median; 19.8), and the resultant total doses of A points ranged between 49.8 Gy and 86.0 Gy (median; 70.6). RESULTS: The five-year overall survival rates of FIGO IB1, IB2, IIA, IIB, III and IVA were 88.3%, 83.3%, 86.1%, 65.2%, 60.0% and 50.0%, respectively (p=0.005). The pelvic control rates of each stage were 90.1%, 85.7%, 86.1%, 69.4%, 68.6% and 50.0%, respectively (p=0.03). From the multivariate analysis, the radiation response and tumor diameter were found to be significant factors affecting the overall survival. The significant factors influencing pelvic control were the radiation response and pre-treatment hemoglobin level. CONCLUSION: The radiation response and tumor diameter were significant factors affecting survival, so patients with tumor diameters greater than 4 cm should be considered for a combined modality, such as concurrent chemoradiotherapy.

BACKGROUND: It has been sugested that excessive airway narrowing in asthma may be detected by a decrease in forced vital capacity (FVC). A volume differrence between slow vital capacity (SVC) and FVC may be used as a surrogate index of airway collapse. OBJECTIVE: To investigate the relationship between an airway collapsibility index (CI) and airflow limitation or airway hyperresponsiveness in asthma. METHODS: Forty-six patients with suspected asthma and 21 normal control subjects were enrolled. CI was defined as a difference between SVC and FVC, and measured before and after a methacholine (MCh) bronchoprovocation test. Positive response to MCh was defined as a fall of FEV1 by more than 12%. RESULTS: CI significantly increased from 1.10+/-3.86% to 5.52+/-7.91% after MCh in the positive MCh group (n=19, p<0.01). Not only FVC but also SVC was significantly decreased after MCh. One-fifth of the decrease in FVC was caused by the increase in CI. Both FVC and SVC were significantly related to baseline FEV1 values and in percent change after MCh. Although CI was also significantly related to FEV1 in percent change after MCh. CI was significantly higher in the positive MCh group than in the control and was not significantly related to baseline FEV1 values. Furthermore, the relationship of CI values between before and after MCh was significant (r=0.622, p<0.01). CI was not significantly different according to the severity of MCh-PC20. CONCLUSION: Because the relationship between CI and the severity of airflow limitation or MCh-PC20 was less significant. CI may be better than FVC to represent the characteristic of excessive airway narrowing in asthma.
