We report 2 cases of pediatric DNTs which presented with intractable seizures and no other associated neurologic abnormalities. They showed typical appearance of DNTs on neuroimaging and histopathology. Most patients with DNT can be cured by surgical treatment with exellent outcome and do not need ratio- or chemotheraphy. This study indicates that it is quite important to consider DNTs as one of differential diagnoses in patients with intractable seizures especially when they present only with seizures without other neurologic symptoms.

OBJECTIVE: To estimate the probable cause and the time of cerebral insult in cerebral palsy (CP) based on MRI findings and risk factors. METHOD: The subjects comprised all sixty-seven patients with CP showing abnormal MRI findings between March 1999 and September 2001 at the Catholic University of Korea, St. Mary's Hospital. A detailed medical history was available for all patients including those not born in our hospital. They ranged in age from two months to five years. We analyzed the brain magnetic resonance (MR) findings of patients with CP to correlate the probable cause and the time of cerebral insult through the consideration of medical histories including prenatal, perinatal and postnatal histories. RESULTS: Of the 67 MRIs, abnormalities were the followings; periventricular leukomalacias (PVLs) in 49 cases, cortical or subcortical infarction in 4 cases, brain atrophy in 7 cases, neuronal migration disorder in 4 cases, and delayed myelination in 3 cases. Among the patients with PVL, perinatal risk factors were responsible for cerebral insult in preterm, but pre- and perinatal contribution were similar in patients born at full term. Among the patients with cerebral infarction, only one case with meningitis at 11 months was suspected for cerebral insult. These patients had no risk factor as a peri- or post-natal etiology. Four patients with neuronal migration disorder had no risk factor for peri- or postnatal etiology except for the one who was a twin. CONCLUSION: Review of brain MRI findings such as PVL, infarct, neuronal migration disorder and a detailed medical history including prenatal and perinatal etiology would be a useful method to estimate the probable cause and the time of cerebral insult in CP.

BACKGROUND: Many patients with end-stage renal disease (ESRD) undergoing hemodialysis (HD) experience depression. Depression influences patient quality of life (QOL), dialysis compliance, and medical comorbidity. We developed and applied a group cognitive behavioral therapy (CBT) program including mindfulness meditation for ESRD patients undergoing HD, and measured changes in QOL, mood, anxiety, perceived stress, and biochemical markers. METHODS: We conducted group CBT over a 12-week period with seven ESRD patients undergoing HD and suffering from depression. QOL, mood, anxiety, and perceived stress were measured at baseline and at weeks 8 and 12 using the World Health Organization Quality of Life scale, abbreviated version (WHOQOL-BREF), the Beck Depression Inventory II (BDI-II), the Hamilton Rating Scale for Depression (HAM-D), the Beck Anxiety Inventory (BAI), and the Perceived Stress Scale (PSS). Biochemical markers were measured at baseline and after 12 weeks. The Temperament and Character Inventory was performed to assess patient characteristics before starting group CBT. RESULTS: The seven patients showed significant improvement in QOL, mood, anxiety, and perceived stress after 12 weeks of group CBT. WHOQOL-BREF and the self-rating scales, BDI-II and BAI, showed continuous improvement across the 12-week period. HAM-D scores showed significant improvement by week 8; PSS showed significant improvement after week 8. Serum creatinine levels also improved significantly following the 12 week period. CONCLUSION: In this pilot study, a CBT program which included mindfulness meditation enhanced overall mental health and biochemical marker levels in ESRD patients undergoing HD.

PURPOSE: We wanted to describe the MR imaging findings of endometrial cancer in patients with a history of prior radiation therapy for cervical cancer (ECRT) and we compare them to the MR imaging findings of patients with spontaneously occurring endometrial cancer (SEC). MATERIALS AND METHODS: Twenty-two patients with endometrial cancer that was diagnosed by operation or endometrial biopsy were included in the study. The patients were divided into two groups according to the presence of past RT for cervical cancer: ECRT (n = 4) and SEC (n = 18). The MR images were retrospectively analyzed by consensus of two experienced radiologists. The MR imaging findings were analyzed by the size, shape and signal intensity of the mass, distension of the uterine cavity, the presence of cervical stenosis and the nature of the fluid collection. RESULTS: For the mass shape, all the ECRT lesions were polypoid masses. However, the SEC patients had 5 polypoid masses and 13 wall thickenings. The maximal diameter, signal intensity and enhancement pattern of the masses were not different between the ECRT and SEC patients. The width of the endometrial cavity varied between 3.9 cm in the ECRT patients and 0.4 cm in the SEC patients (p =0.002). All the ECRT patients had cervical stenosis. However, none of the SEC patients had cervical stenosis. CONCLUSION: MR imaging of ECRT patients demonstrated prominent distension of their uterine cavity and cervical stenosis, which may be the result of radiation fibrosis in the uterus.

PURPOSE: In the Spring 1995, there was an outbreak of adenoviral infection, which caused four death out of ten patients with adenoviral pneumonia in our hospital. Clinical courses of ten patients with severe pneumonia were similar each other, and two were confirmed as adenoviral pneumonia by postmortem autopsy. Although not proven, we believe eight patients had adenoviral pneumonia. Therefore, we report clinical features in ten cases of severe adenoviral pneumonia. METHODS: Two cases with adenoviral pneumonia and eight cases with presumed adenoviral pneumonia were admitted in this hospital from March to June, 1995. Age and sex distribution, clinical manifestations, laboratory data, chest X-ray findings were reviewed. RESULTS: They were young children between 4 to 25 months of age(mean 12.7+/-6.1 months), and male to female ratio was 9:1. They presented with abrupt fever, cough, tachypnea, and dyspnea. Mean duration of fever were 12.7+/-6.1 days. Crackles on auscultation were heard in all patients. Studies for Mycoplasma and Tuberculosis were all negative. Cultures of bacteria and fungi were negative, and they did not respond to the antibiotics. The chest X-ray revealed the diffuse lobar consolidation with varying amount of pleural effusions. The findings of pleural fluid showed characteristics of transudate with predominant monocyte. Eight of our severe adenoviral pneumonia patients were enjoying normal health previously. Only two patients had previous medical problems, one with chronic cytomegalovirus pneumonia and the other with neutropenia induced by phenobarbital. The course of illness suggests that the infection was hospital acquired and the final outcome was fatal. Three of them developed seizure with fever, five change of consciousness, four conjunctivitis, three otitis media, and two gastro-intestinal symptoms. Autopsy was done in two of four patients. Grossly, the lungs were heavy and dark- red in color. There were bilateral pneumonic consolidation with patchy areas of hemorrhage. Microscopically, severe necrotizing bronchitis and bronchiolitis with numerous intranuclear inclusion of Cowdry type A and B were found. Alveoli were edematous and filled with fibrinous exudate, and covered with hyaline membrane. Ultrastructurally, typical adenoviral particles showing hexagonal shape in paracrystalline array symmetry were found in the nucleus of aleveolar lining cells. CONCLUSIONS: Yet, occasionally, adenoviral infection becomes most aggressive form of pneumonia. We should consider adenoviral pneumonia when clinical findings of pneumonia are very similar with baterial pneumonia except poor response to broad spectrum antibiotics. There is no specific treatment for adenoviral infection. So, for prevention of adenoviral pneumonia, we recommend isolation in suspicious adenoviral infection.

Congenital accessory limbs are very rare anomalies with many causative factors. We describe the case of a 1-day-old female neonate-born to a healthy, 27-year-old mother-who presented with an accessory limb (foot) attached to the buttock and an imperforate anus. We also provide a review of the relevant literature.

It is important to initialize Image Plate (IP) completely for removing residual latent image by sodium lamp for reliability and repeatability of computed radiography (CR) system. The purpose of this study was to evaluate latent images of computed radiography (CR) images respect to delay time after erasure of foregone latent image and its effect, and erasure level. Erasure thoroughness for CR acceptance test from American Association of Physicist in Medicine (AAPM) Report 93 (2006) was also evaluated. Measurements were made on a CR (Agfa CR 25; Agfa, BELGIUM) system. Chest postero-anterior (PA), Hand PA, L-spine lateral radiographs were chosen for evaluation. Chest phantom (3D-torso; CIRS, USA) was used for Chest PA and L-spine lateral radiography. For Hand PA radiography, projections was done without phantom. Except Hand PA radiographs, noise was increased with delay time, and ghost image was appeared on overexposed area. Effect of delay after erasure on latent image was not seen on naked eye, but standard deviation (SD) of pixel value on overexposed area was relatively higher than that of other areas. On Hand PA and Chest PA radiographs, noise were not occurred by adjustment of erasure level. On L-spine lateral images at lower erasure level than standard level, noise including ghost image were occurred because of high tube current. Erasure thoroughness of CR system in our department was to be proved by these evaluation. The results of this study could be used as a baseline for IP initialization and reliability of CR images.

STATEMENT OF PROBLEM: The effect of gold electroforming on gold alloy was not studied. PURPOSE: This in vitro study investigate the effect of gold electroforming on gold-silver-palladium alloy. MATERIAL AND METHODS: Three pieces of gold strips had undergone the electroforming procedures on one side and then half of the side again electroformed. The set mode for this study was program 1 (200 micrometer). And the processing time was 15min (1/20 time to form 200 micrometer coping). The confocal laser scanning microscope (PASCAL 5, Carl Zeiss, Bernried, Germany) was used to measure the thickness of the pure gold layer electroformed on the gold strips. Half of the gold strip was coated two times with electroformed gold, and the other half one time. The data from the cone focal laser system was processed to get the vertical profile of the strips and the difference of the vertical height between the double coated and single coated layer was regarded as the thickness of the gold coating. The layer thickness value to built 3D image of the cone-focal laser was set 0.5 micrometer. Next to the measurement of the thickness of the coating, the Vicker's hardness test was done. It was performed on the double coated surface, single coated surface and non-coated surface (back side) three times each. RESULTS: The mean thickness value gained from gold electroforming technique was measured to be 22 micrometer for sample 1, 23 micrometer for sample 2, 21 micrometer for sample 3. In the same condition of time, power and the amount of electrolyte, the data showed no difference between samples. According to the results of variance analysis, the differences among the variations in number of coating were statistically insignificant (p>0.05), meaning that the two times of gold electroforming coating did not change the hardness of gold-silver-palladium alloy. CONCLUSION: The test of thickness of gold coating proved the coherency of the gold electroforming procedure, in other words, when the power, the exposed surface area, processing time and the amount of electrolytes were set same, the same thickness of gold would be coated on. The hardness test showed that the electroformed gold coating did not change the hardness of the gold-silver-palladium alloy when it is coated not more than 45 micrometer.

Uterine adenosarcoma (AS) are rare tumors and have more favorable outcomes than the aggressive uterine carcinosarcomas. Uterine adenosarcoma with sarcomatous overgrowth (ASSO) is a variant form of AS and exhibits aggressive growth of tumor and the prognosis is relatively poor compared with typical AS. Usually patterns of metastasis have been known to behave like endometrial carcinoma and spread through the lymphatics. Brain metastasis from uterine AS is extremely rare. Herein, we report a case of successfully surgically removed solitary brain metastasis without any extracranial recurrence from uterine ASSO after 4 years of primary treatment.
