Spinal epidural abscesses were evaluated using Gadolinium-enhanced magnetic resonance imaging (MRI) in 19 surgically and clinically confirmed cases, including 13 with tuberculous spondylitis and 6 with pyogenic spondylitis. We observed rim enhancement patterns in 10 patients and diffuse enhancement patterns in 9 patients. The spread patterns were localized to ventral or dorsal epidural space and encircled entire epidural space. We conclude that rim enhancement indicates abscess and diffuse enhancement indicates granulation tissue and fibrosis. Tuberculous epidural abscess spreads to ventral epidural space and pyogenic epidural abscess encircles entire epidural space.

Milk of calcium located in the breast is typically a benign entity. However, carcinoma may incidentally arise adjacent to or even within milk of calcium. Consequently, the characteristics of all observed calcific particles should be carefully analyzed. In this study, we report a case of carcinoma presented as malignant microcalcifications mixed within milk of calcium in a breast.

PURPOSE: To evaluate the incidence of sacral insufficiency fracture in osteoporotic patients with compression fracture of the thoracolumbar (T-L) spine on magnetic resonance image (MRI), and to analyze the correlation of variable clinical factors and the incidence of sacral insufficiency fracture. MATERIALS AND METHODS: We retrospectively reviewed 160 patients (27 men, 133 women; age range of 50 to 89 years) who underwent spinal MRI and had compression fracture of the T-L spine. Compression fractures due to trauma or tumor were excluded. We evaluated the incidence of sacral insufficiency fracture according to the patients' age, sex, number of compression fractures, and the existence of bone marrow edema pattern of compression fracture. During the same period, we evaluated the incidence of spinal compression fracture in the patients of pelvic insufficiency fracture. RESULTS: Out of the 160 patients who had compression fracture in the T-L spine, 17 (10.6%) had insufficiency fracture of the sacrum. Compression fracture occurred almost 5 times more frequently in women (27:133), but the incidence of sacral insufficiency fracture was 2/27 for men (7.4%) and 15/133 for women (11.3%), with no statistically significant difference (p = 0.80). According to age, the ratio of insufficiency fracture to compression fracture was 0% (0/23) in the 50's, 10.6% (7/66) in the 60's, 12.5% (7/56) in the 70's, and 20.0% (3/15) in the 80's. In respect of single and multiple compression fracture, the incidence of sacral insufficiency fracture was 8/65 for men (12.3%) and 9/95 for women (9.5%), showing no significant difference (p=0.37). In the patients with and without compression fracture with bone marrow edema, insufficiency fracture occurred in 5/76 (6.6%) and 12/84 (14.3%), respectively. On the other hand, of the 67 patients who had pelvic insufficiency fracture, 27 (40.3%) also had spinal compression fracture. CONCLUSION: About 10% of the patients with osteoporotic compression fracture in the T/L spine also had pelvic sacral insufficiency fracture, which was not uncommon. These findings suggest the need to consider the possibility of pelvic sacral insufficiency fracture in cases of T/L spinal MRI for patients with osteoporotic compression fracture.

The purpose of this study was to evaluate changes in the microbiological safety of food ingredients supplied to elementary school food services during processing. For this purpose, fifteen food ingredients and twelve factories were chosen in the provinces of Daegu and Gyeongbuk. Total plate counts and coliform counts were reduced in the ingredients after washing, but they increased after packing. After packing, the following levels of total plate counts and coliforms were detected, respectively: peeled bellflower roots (1.2~3.6x10(6), 3.1~4.6x10(5) CFU/g), blanched vegetables (5.6x10(3)~2.0x10(5), <5~1.5x10(4) CFU/g), soybean curd ( <5~5.4x10(3), <5~2.2x10(3) CFU/g), buckwheat starch jelly ( <5, <5 CFU/g), soybean sprouts (1.2x10(6)~1.8x10(7), 2.4x10(5)~4.3x10(6) CFU/g), mackerel (2.2x10(2), 1.3x10(2) CFU/g), chicken (3.8x10(4), 6.7x10(2) CFU/g), pork (6.7x10(2), <5 CFU/g), and beef (9.4x10(2)~5.2x10(4), <5~2.1x10(3) CFU/g). Generally, the microbiological safety of the food ingredients was better during the processing stage than during the other stages, with the exception of packing. Staphylococcus aureus, E. coli, and Bacillus cereus were detected in small amounts on the peeled bellflower roots, chicken, and pork, respectively. These results indicate that peeled bellflower roots, chicken, and pork need to be sanitized at the washing stage and cross contamination must be prevented at the packing stage.

OBJECTIVE: The purpose of this retrospective study was to investigate short-term and long-term skeletodental outcomes of Class III activator treatment. METHODS: A Class III activator treatment group (AG) comprised of 22 patients (9 boys, 13 girls) was compared with a Class III control group (CG) comprised of 17 patients (6 boys, 11 girls). The total treatment period was divided into three stages; the initial stage (T1), the post-activator treatment or post-mandibular growth peak stage (T2), and the long-term follow-up stage (T3). Cephalometric changes were evaluated statistically via the Mann-Whitney U-test and the Friedman test. RESULTS: The AG exhibited significant increases in the SNA angle, ANB angle, Wits appraisal, A point-N perpendicular, Convexity of A point, and proclination of the maxillary incisors, from T1 to T2. In the long-term follow-up (T1-T3), the AG exhibited significantly greater increases in the ANB angle, Wits appraisal, and Convexity of A point than the CG. CONCLUSIONS: Favorable skeletal outcomes induced during the Class III activator treatment period were generally maintained until the long-term follow-up period of the post-mandibular growth peak stage.

Anti-GQ1 antibody is found in patients with Miller-Fisher syndrome (MFS), atypical MFS, and Bickerstaff's brainstem encephalitis (BBE). These conditions are various manifestations of post-infectious autoimmune disorders, and anti-GQ1b antibodies play a core pathogenic role. So they are referred as the 'anti-GQ1b antibody syndrome'. We report two cases of recurrent anti-GQ1b antibody syndrome.

OBJECTIVE: The purpose of this study was to assess rotational patterns of dentofacial structures according to different vertical skeletal patterns by cone-beam computed tomography (CBCT) and analyze their influence on menton deviation in skeletal Class III deformity with mandibular asymmetry. METHODS: The control group consisted of 30 young adults (15 men, 15 women) without any severe skeletal deformity. The asymmetry group included 55 adults (28 men, 27 women) with skeletal Class III deformity and at least 3-mm menton deviation from the midsagittal plane; it was divided into the hyperdivergent and hypodivergent subgroups using a mandibular plane angle cutoff of 35degrees. Fourteen rotational variables of the dental arches and mandible were measured and compared among the groups. Correlations between menton deviation and the other variables were evaluated. RESULTS: The asymmetry group showed significantly larger measurements of roll and yaw in the mandible than the control group. The hypodivergent subgroup showed significant differences in maxillary posterior measurements of yaw (p < 0.01) and maxillary anterior shift (p < 0.05) compared with the hyperdivergent subgroup. All the mandibular measurements had significant correlations with menton deviation (p < 0.01). Most measurements of roll were positively correlated with one another (p < 0.01). Measurements of yaw and roll in the posterior regions were also positively correlated (p < 0.05). CONCLUSIONS: Menton deviation in skeletal Class III deformity with mandibular asymmetry is influenced by rotation of mandibular posterior dentofacial structures. The rotational patterns vary slightly according to the vertical skeletal pattern.

BACKGROUND: Pain on injection of rocuronium is a common clinical problem. We compared the efficacy of lidocaine, ketorolac, and the 2 in combination as pretreatment for the prevention of rocuronium-induced withdrawal movement. METHODS: For this prospective, randomized, placebo-controlled, double-blind study a total of 140 patients were randomly allocated to one of 4 treatment groups to receive intravenously placebo (saline), lidocaine (20 mg), ketorolac (10 mg), or both (n = 35 for each group), with venous occlusion. The tourniquet was released after 2 min and anesthesia was performed using 5 mg/kg thiopental sodium followed by 0.6 mg/kg rocuronium. The withdrawal response was graded on a 4-point scale in a double-blind manner. RESULTS: The overall incidence of withdrawal movements after rocuronium was 34.3% with lidocaine (P = 0.001), 40% with ketorolac (P = 0.004), and 8.6% with both (P < 0.001), compared with 74.3% with placebo. There was a significantly lower incidence of withdrawal movements in patients receiving the lidocaine/ketorolac combination than in those receiving lidocaine or ketorolac alone (P = 0.009 and 0.002, respectively). The incidence of moderate to severe withdrawal movements was 14.3% with lidocaine, 17.2% with ketorolac, and 2.9% with lidocaine/ketorolac combination, as compared to 45.7% with the placebo. There was no significant difference in withdrawal movement between the lidocaine group and the ketorolac group. CONCLUSIONS: Ketorolac pretreatment had an effect comparable to that of lidocaine in attenuating rocuronium-induced withdrawal movements and the lidocaine/ketorolac combination pretreatment, compared with lidocaine or ketorolac alone, effectively reduced withdrawal movements during rocuronium injection.

PURPOSE: This study aimed to determine the amino acids composition, safety and efficacy of formulas recently developed by Korean dairy companies for children with inherited metabolic disorder. METHODS: The determination of amino acids concentration was performed on eight Korean formula samples. The samples were hydrolyzed with 6N HCL or performic acid and analyzed by amino acid analyzer. RESULTS: No phenylalanine, methionine or leucine was observed in PKU-1 and PKU-2 Formulas, Methionine-Free and Leucine-Free Formula, respectively. BCAA-Free Formula was free from leucine, isoleucine, and valine and MPA Formula did not contain methionine and valine. Protein-Free formula did not include any amino acids. UCD Formula contained arginine but was free of alanine, aspartic acid, glutamic acid, glycine, histidine, proline and serine. Methionine-Free Formula contained higher amounts of cystine and tyrosine was higher in PKU-1 and 2 Formulas. The amounts of isoleucine and threonine were minimal in MPA Formula. CONCLUSION: This study confirmed that the eight special formulas, developed for the first time by a Korean dairy company for children with inherited metabolic disorder contain appropriate amino acids with proper contents. Both the total amino acid amounts and specific amino acid concentrations of the formulas were appropriate for related diseases, which could be used safely by the patients with inherited metabolic disorder. For UCD Formula that contains arginine, we suggest that arginine be removed from the formula in order to use for any urea cycle defect patients before the specific diagnosis is made.

BACKGROUND: Spinal anesthesia causes hypotension and bradycardia due to sympathetic nerve block and it is difficult to predict the level of sensory block and the duration of blockade. Recent studies have reported that intravenous phenylephrine can reduce the rostral spread of spinal anesthesia in pregnant women. We think a phenylephrine infusion will be useful for maintaining the baseline blood pressure by reducing the rostral spread of spinal anesthesia during the elective surgery of non-obstetric patients. METHODS: Sixty patients who were undergoing urologic surgery were randomized into two groups: Group C (the control group without phenylephrine) and Group P (with the addition of phenylephrine). After a bolus infusion of 50 microg phenylephrine following the spinal injection, phenylephrine was continuously infused at the rate of 200 microg/hr. We compared the dermatomal spreads of spinal anesthesia, the hemodynamic parameters (blood pressure, heart rate) and the incidences of hypotension between the two groups. RESULTS: At 20 minutes, the level of the upper dermatome blocked against cold sensation was a median of T8 (interquartile range: T8-T10) for the phenylephrine group, as compared with T4 (interquartile range: T4-T6) for the control group (P < 0.001). CONCLUSIONS: Intravenous phenylephrine can decrease the rostral spread of spinal anesthesia during urologic surgery.
