This study was conducted to investigate the validity of using a cameraphone for a dietary intake survey method. The subjects were 28 female college students. After eating a standard lunch meal which consisted of plain rice, seaweed soup, bulgogi, cucumber salad, roasted anchovy and kimchi, the quantity of dietary intake, calorie intake & nutrients intake were analyzed by weighed method, diet record method and cameraphone method by dietitian with & without cameraphone analysis training. There were no significant differences in the quantity of 6 foods intake between weighted method and cameraphone method by dietitians with camera phone analysis training. However, the quantity of seaweed soup, bulgogi & cucumber salad intake analyzed by diet record method was significantly lower than the weighed method. And the quantity of seaweed soup, bulgogi, cucumber salad, roasted anchovy and kimchi intake analyzed by the cameraphone method by dietitians without cameraphone analysis training was significantly lower than the weighed method. There were no significant differences in the calorie intake and nutrients intake between the weighted method and camera phone method by dietitians with camera-phone analysis training. However, protein, calcium, iron, phosphorous, Vitamin A, Vitamin B2, Vitamin E and cholesterol intake analyzed by diet record method was significantly lower than the weighed method. And fat and Vitamin B2 intake analyzed by the camera phone method by dietitians without cameraphone analysis training was significantly lower than the weighed method. Therefore, this study suggests that the use of the camerephone may be a valid and convenient method for evaluating a dietary intake survey. However, systematic and standard education is necessary about the size and volume of dishes and angle of photo for more accurate results.

PURPOSE: In the present study, the dependence of intraocular pressure (IOP) on body position was compared between pseudophakic and phakic eyes after cataract surgery performed at least 3 months prior. METHODS: IOP was measured in 214 patients over 40 years of age who received cataract surgery at least 3 months prior. The present study included 104 patients who did not have any other ocular disease which could influence visual acuity or IOP. The IOP was measured in 4 different positions, sitting, supine, right decubitus, and left decubitus by a single skilled researcher using Icare tonometer. In addition, IOP was compared between the phakic and pseudophakic eyes, specifically, the dependent eye in the decubitus position. RESULTS: The comparison between the phakic and pseudophakic eyes in patients after cataract surgery in a single eye showed IOP was not different between the sitting and supine positions; however, in the decubitus position, IOP in the dependent eye was significantly higher than the non-dependent eye (p = 0.001). Additionally, regardless of lens status, IOP was significantly higher in the dependent eye than non-dependent eye. CONCLUSIONS: Both body position and lens status can affect IOP. After cataract surgery, regardless of lens status, IOP was higher in the dependent eye than non-dependent eye of patients in the decubitus position.

PURPOSE: To report peripheral vascular retinal leakage findings of asymptomatic eyes based on fluorescein angiography, and investigate the associated factors. METHODS: Data were collected retrospectively from 47 subjects (94 eyes) and the peripheral leakage results based on fluorescein angiography were analyzed. The relationship between peripheral leakage findings and other factors including-arm-retinal circulation time (ARCT) and venous filling time (VFT), refractive error, age, hypertension, and diabetes- was evaluated. RESULTS: Ten eyes had peripheral leakage (21.3%). The mean age was 34.7 +/- 7.86 years in the non-leakage group and 44.3 +/- 9.63 years in the leakage group; the difference between the groups was statistically significant (p = 0.001). The mean spherical equivalent was -2.85 +/- 2.71 diopter in the non-leakage group and -3.46 +/- 3.62 diopter in the leakage group; the difference between the groups were not significant (p = 0.471). The mean ARCT was 10.50 +/- 2.06 seconds in the non-leakage group and 11.76 +/- 2.47 seconds in the leakage group; the difference between the groups was statistically significant (p = 0.041). The mean VFT was 9.70 +/- 1.91 seconds in the non-leakage group and 10.75 +/- 1.40 seconds in the leakage group; the difference between the groups was statistically significant (p = 0.048). CONCLUSIONS: Peripheral leakage can be found in asymptomatic eyes. Age, VFT, and ARCT were correlated to peripheral leakage findings based on angiography. These leakage findings were thought to be related with histological properties and physiological changes in peripheral retina.

BACKGROUND: Neuromuscular blocking drugs are designed to specifically block nicotinic cholinergic receptors at the neuromuscular junction, but many bind to muscarinic cholinergic receptors on ganglia, nerve endings, and smooth muscles, thereby altering parasymphathetically mediated airway caliber and heart rate. METHODS: We studied the effects of mivacurium on the tension of tracheal smooth muscle by using an isolated rat tracheal preparation. We studied the cumulative effect of acetylcholine after pretreating the tracheal smooth muscle with mivacurium at different concentrations, as well as the effect of L-NAME and propranolol on the tension of tracheal smooth muscle after pretreating with mivacurium. RESULTS: Mivacurium shifted the acetylcholine dose-response curve to the right. L-NAME and propranolol had no effect on the tension of tracheal smooth muscle after pretreating with mivacurium. CONCLUSIONS: We have found that mivacurium relaxes isolated rat tracheal smooth muscle and this effect has no relationship to beta-receptors or nitric oxide.

PURPOSE: To determine the long-term repeatability of diurnal intraocular pressure (IOP) patterns in healthy Asian subjects without glaucoma. METHODS: Twenty-three eyes in 23 healthy Asian subjects without glaucoma underwent diurnal IOP measurements using Goldmann applanation tonometry every 2 hours from 9 AM to 11 PM during two visits that were 8 weeks apart. To validate repeatability between visits, we calculated intra-class correlation coefficients (ICCs) mean IOP, peak IOP, minimum IOP, and IOP fluctuation at each time point and expressed the results as the difference between peak IOP and minimum IOP or as the standard deviation of all diurnal IOP values in the diurnal IOP curve. RESULTS: IOP repeatability was excellent at all time points, with ICCs ranging from 0.812 to 0.946 (p < 0.001). The 9 AM IOP showed the best repeatability between visits (ICCs, 0.946). Repeatability of mean IOP, peak IOP, and minimum IOP was also excellent (ICCs ranging from 0.899 to 0.929). However, IOP fluctuations showed poor repeatability, with an ICC lower than 0.15. CONCLUSIONS: Long-term repeatability of diurnal IOP patterns in healthy Asian subjects was excellent. These findings suggest that IOP measurements at standardized times of the day will be useful for assessing the effectiveness of glaucoma therapy.

PURPOSE: Using transmission electron microscopy (TEM), we studied the ultrastructures of rapidly proliferating preretinal membranes of young patients with very extensive ischemic proliferative diabetic retinopathy and diabetes with uncontrollable blood sugar level. METHODS: Nine cases of preretinal membranes were obtained from six eyes of five patients with rapidly progressed proliferative diabetic retinopathy (mean age, 35 years) during vitrectomy. We obtained each preretinal membrane bimanually as one single sheet membrane using intraocular scissors and forceps. Each tissue was fixed in 3% glutaraldehyde in the operating room. All specimens were prepared and studied using TEM. RESULTS: The preretinal membranes were composed of blood vessels and some interstitial cells. The blood vessels within the preretinal membranes varied in developmental stages, from the immature stage to the mature stage. The blood vessels were highly active, in that primitive cells showed a large nucleus and prominent chromatin clumping with abundant cytoplasm. Highly active fibroblast-like cells were also noted. CONCLUSIONS: We observed highly active angiogenesis in preretinal membranes, which rapidly proliferated in cases of severe retinal ischemia in young diabetes patients. This is the first report of such a finding, which may help to explain the poor prognosis of this disease modality.

Brucella endocarditis is a rare complication, but it is responsible for the majority of deaths related to this illness. A 67 year-old man presented with complaints of fever and lower back pain that he had experienced during the previous four weeks. The laboratory finding showed pancytopenia and an inverted total protein/globulin ratio. Multiple myeloma was diagnosed by bone marrow biopsy and serum electrophorosis. The spine MRI scan demonstrated spondylitis with epidural abscess (L5-S1). On the echocardiographic examination, there was vegetation on the right coronary cusp of the aortic valve and perivalvular abscess. The blood isolate was confirmed as Brucella abortus by using DNA sequencing of the 16S rRNA and the omp2a and omp2b genes. The clinical manifestations improved after appropriate antibiotics and aortic valve replacement. We describe here the first Korean case of human brucella endocarditis that was treated by valve replacement.

We review the effect of methylphenidate, focusing on Osmotic-controlled Release Oral delivery System (OROS) methylphenidate, on cardiovascular system, appetite and growth, sleep, tic, epilepsy, psychiatric and rare adverse events. Although OROS methylphenidate has side effects including increased heart rate or blood pressure, decreased appetite, delayed sleep onset, emergence or aggravation of tics, withdrawal or changes in mood, these effects appeared to be minimal in impact or difficult to distinguish from risk to untreated population and tended to be improved by dose adjustment or drug discontinuation. However, in subjects with underlying cardiac problems, uncontrolled epilepsy, previous psychotic episode, clinicians should pay attention and balance the risk and benefit.
