Tibialis anterior muscle hernia is the most common hernia among lower extremity muscles. This condition can be diagnosed by physical examination and radiologic findings, especially by dynamic ultrasonography. There are surgical methods of treatment for muscle hernia, including direct repair, fasciotomy, fascial patch grafting using autologous fascia lata or synthetic mesh. We report a case of tibialis anterior muscle hernia treated with local periosteal rotational flap. Because there are several advantages to the local periosteal rotational flap, such as lack of donor site morbidity, lack of skin irritation, low cost, simplicity, and an easy approach, this technique could be an option for tibialis anterior muscle hernia.

PURPOSE: We performed this study to evaluate the usefulness and the limitation of magnetic resonance angiography in imaging portal vein and hepatic vein. MATERIALS AND METHODS: Magnetic resonance portography was performed in five normal subjects and seven patients with hepatomas, two patients with Budd-Chiari syndromes, one patient with liver cirrhosis and one patient with hepatic metastasis from stomach cancer. Magnetic resonance angiography was done with a 1.5-T Scanner. Breath-hold two-dimensional time-of flight images with spoiled gradient echo technique were acquired. Scan parameters were 34/8/40degrees(TR ms/TE ms/flip angle). The portal vein and the hepatic vein were selectively imaged by applying two presaturation bands. These images were then postprocessed by a maximum intensity projection algorithm. MRA findings were compared with ultrasonography in all cases of the hepatic disease, and conventional angiography (SMA portography) in four cases. RESULTS: In normal subjects, the splenic vein, intrahepatic and extrahepatic portions of the portal vein, and the hepatic veins were well visualized. In the patients with hepatic diseases, the varices (4 cases), the splenorenal shunts (2 cases), and the recanalized umbilical vein (1 case) were demonstrated. There were portal vein thrombosis in the cases of hepatomas and hepatic metastasis. In the cases of Budd-Chiari syndrome, the hepatic veins were not visualized and there were inferior vena cava obstructions with multiple collateral vessels. CONCLUSION: Compared with ultrasonography, MRP may be useful in evaluation of varices, splenorenal shunts, and other collaterals, though less accurate than conventional angiography. MRP can be useful as a noninvasive screening alternative in the evaluation of portal vein and hepatic veins.

As a series of systematic classification for Korean common liver fluke, Fasciola sp., karyotype was investigated by means of the modified air-drying technique and of the regular Giemsa staining, Also, C-staining method was applied for detailed karyological analysis from the germ cells of the fluke. The following is a brief summary of the leading facts gained through the experiment. Korean Fasciola sp. was classified into three types based on their chromosomal complements; individuals with 20 or 30 chromosomes and with a 20/30 mosaic constitution. Worms having 30 chromosomes represent a triploid form with 3 sets of 10 basic chromosomes, while those with 20 chromosomes were diploid and mosaic individuals were 2n/3n mixoploid. The frequency of the individual type calculated is as follows; 67.45% of 212 flukes examined was of diploid, 10.85%, triploid, and the rest, 21.7%, mixoploid, respectively. In many cases, two or three types were found in the peculiar bovine host while single type inhabitant was about 20% out of 52 cases. The twenty chromosomes consisted of 1 parir of large metacentrics, 4 pairs of medium-sized subtelocentrics, and 5 pairs of small submetacentrics, while constitution of the thirty chromosomes was nearly interpreted as a triploid form with 3 sets of 10 basic chromosomes. The high centromeric indexes of both types are the first pairs among all the examined, and 37.93% was of diploid and 47.93%, triploid, respectively. In mixoploid individuals, constitution of the chromosomes of diploid or triploid cells was the same as that of diploid or triploid individuals. All the chromosomes of the germ cells in both types showed C-band around the centromeic region and especially the chromosomes no's 3, 7, and 8 showed a remarkable C-band distinguished from other chromosomes. The variance for the sizes of the worms and the eggs were not parallel with three different genotypes in Korean common liver fluke.

PURPOSE: Besides interferencence of esophageal motor function by the nasogastric tube, a decline of the positive gastro-esophageal pressure gradient caused by intermittent positive pressure ventilation seems to have a major role in the pathogenesis of gastroesophageal reflux (GER) in mechanically ventilated preterm infants. The aim of this study was to determine the incidence of GER and associated risk factors in mechanically ventilated preterm infants. METHODS: Twenty four hour esophageal pH monitorings were performed using a antimony electrode on 11 mechanically ventilated preterm infants in Neonatal Intensive Care Unit in Pusan National University Hospital. We evaluated the following reflux parameters; reflux index, reflux episodes/ hour, reflux episodes > or =5 min/hour, duration of longest episode, and percent episodes > or =5 min. Patients were considered to have significant GER if more than 2 among 5 parameters were satisfied. RESULTS: The mean gestational age of the patients was 30.9 weeks, mean birth weight was 1,568 g, and mean age at the time of pH monitoring was 2.8 days. Significant GER was detected in 4 patients (36.4%). There was no relationship between the incidence of GER and gestational age, birth weight, postnatal age, or the ventilator settings. CONCLUSION: The incidence of GER in mechanically ventilated preterm infants was similar, compared with other previous studies. Associated risk factors of GER in these patients were not detected. Therefore, mechanical ventilation in preterm infants does not seem to be the high risk factor of GER.

BACKGROUND AND OBJECTIVES: There are caloric test, SCEP, DP in Step velocity and VOR asymmetry in SHA test as parameters for evaluation in unilateral peripheral vestibulopathy in parameter of vestibular function test. The aim of this study is to assess the correlation between these parameters and intensity of spontaneous nystagmus in vestibular neuritis. MATERIALS AND METHOD: We evaluated 75 patients who were diagnosed as vestibular neuritis with 3 degree spontaneous nystagmus at vestibular function test lab from January 2000 to July 2005 in Dankook university hospital. The correlations between direction and intensity of spontaneous nystagmus and monothermal caloric test, SCEP and DP in step velocity, VOR asymmetry (0.01, 0.04, 0.16 Hz) in SHA test were analysed. And correlations according to sex, age were also analysed. RESULTS: The correlation coefficient between intensity of spontaneous nystagmus and monothermal caloric test was 0.60. The correlation coefficient between intensity of spontaneous nystagmus and SCEP was 0.35. The correlation coefficient between intensity of spontaneous nystagmus and Tc DP was 0.36 and it showed no significant correlation. The correlation coefficient between intensity of spontaneous nystagmus and VOR asymmetry (0.01, 0.04, 0.16) was 0.57, 0.46, 0.51, respectively and there was higher correlation in man, age under 60. CONCLUSION: Intensity of spontaneous nystagmus showed close relations to monothermal caloric test, VOR asymmetry of SHA, Tc DP, SCEP DP in sequence. In addition, young male patients tends to be closely related to intensity of spontaneous nystagmus.

BACKGROUND: Corticobasal degeneration (CBD) is a rare neurodegenerative disorder involving the cortical and subcortical areas enabling it to cause abnormalities of both cognition and movement. In some reports, CBD has been known to develop variable degrees of intellectual, memory and language impairment. However, detailed neuropsychological assessments of CBD up to now have been few. We conducted a detailed neuropsychological investigation and FDG-PET to delineate the pattern of neuropsychological dysfunction of CBD and to correlate neuropsychological dysfunction with FDG-PET findings. METHODS: All 6 patients (5; right handedness, 1; left handedness) were diagnosed with CBD using clinical criteria. All the patients underwent detailed neuropsychological and brain FDG-PET tests. RESULTS: Neuropsychological tests showed multiple cognitive dysfunctions with moderate memory impairment. FDG-PET scans showed asymmetric decreased metabolism in bilateral fronoto-temporo-parietal cortical and subcortical areas. The extent of asymmetricity was greater on the subcortical than cortical areas. Unlike previous reports, the medial temporal and fronto-parietal metabolisms were similarly depressed. CONCLUSIONS: All CBD patients displayed prominent deficits on mostly cognitive domains. FDG-PET may explain the relation between cognitive dysfunctions and cortical hypometabolism and help differentiate CBD with other dementing disorders.

PURPOSE: To report one case of recurrent Valsalva retinopathy presented as subretinal hemorrhage associated with exercising a barbell in a healthy man. METHODS: A 47-year-old healthy man visited our hospital complaining of a pericentral blind-spot in the right visual field. At first visit, visual acuity was 20/20 without correction. Anterior segment examination was unremarkable and dilated fundus examination revealed a subretinal hemorrhage in the inferior area of the macula. We followed up the visual acuity, anterior segment exam, fundus examination, and fluorescein angiography for several weeks. RESULTS: Three weeks after the first visit, the size of subretinal hemorrhage decreased, but recurrent subretinal hemorrhage presented after exercising a barbell at the existing hemorrhagic part and its inferior area. Six weeks after the recurrent hemorrhage, the hemorrhage was resolved completely and the pericentral blind-spot was recovered. CONCLUSIONS: Valsalva hemorrhagic retinopathy is characterised by retinal hemorrhage occurring in healthy individuals due to a rapid rise in intrathoracic or intra-abdominal pressure. In this case, there was recurrent subretinal hemorrhage after repeatedly exercising a barbell. So, it is very important to educate patients about the restriction of excessive Valsalva maneuver to prevent recurrent Valsalva retinopathy.
