Background: We recently introduced the Barricor (BD, Franklin Lakes, NJ, USA) plasma separation tube, which uses a mechanical separator instead of a gel. We evaluated the effects of using the Barricor tube in a stat (statin) laboratory on the results and turnaround time (TAT) of routine chemical tests. We verified the impact of Barricor tube on reducing TAT and providing results similar to those obtained using serum separator tubes (SSTs). Methods: We collected venous blood samples from 166 outpatients in Barricor tubes and SSTs and measured 28 routine analytes using an AU5800 instrument (Beckman Coulter, Brea, CA, USA). TAT indexes were compared before and after using Barricor tube. Results: Mean percent differences were < 5%, except for alanine aminotransferase , total CO2, high-density lipoprotein, phosphate, total protein, and direct bilirubin. The median TAT decreased from 45 to 38 minutes, and the rate of a TAT > 60 minutes decreased from 7.84% to 2.66%, which was approximately one-third of that for SST. The reduction in TAT was attributable to a decrease in centrifugation time. Incomplete clotting and repeated centrifugation, which occurred frequently when using SST, also decreased after using the Barricor tubes. Conclusions The Barricor tube is an alternative to SST for routine chemical tests in institutions aiming to reduce TAT, with clinically allowable differences in test results.

BACKGROUND: The laparoscopic adrenalectomy has become the standard procedure of adrenal surgery owing to its advantage of minimally invasive surgery and to rapid developments in the laparoscopic technique and apparatus. A posterior retroperitoneoscopic adrenalectomy is a new alternative to both the conventional open approach and a transperitoneal laparoscopic adrenalectomy. This technique is known to be technically difficult and is less frequently done than a transperitoneal laparoscopic adrenalectomy. However, recently, a number of acceptable results have been reported for this procedure. GOAL: We report our experience with and the results from 16 cases involving a retroperitoneoscopic adrenalectomy and evaluate the advantages and disadvantages of this technique. MATERIALS AND METHOD: Between November 1996 and November 1997, a total of 16 retroperitoneoscopic adrenalectomies were performed. All 16 cases had unilateral adrenal tumors(size 1.5-6 cm): 8 Conn adenomas, 4 Cushing adenomas, 2 neurogenic tumors, 1 nonfunctioning adenoma, and 1 vascular cyst. The operations were carried out in the prone position in all cases. Three trochars were inserted below the lower posterior costal margin. The balloon dilatation technique with a surgical globe was used to induce pneumoretroperitoneum in the first 10 cases but in the last 6 cases, the cavity was made only by blunt dissection with the scope and laparoscopic dissector. RESULTS: Fourteen adrenalectomies were completed endoscopically. One was converted to an open posterior approach due to severe skin emphysema and the other case was converted to an open anterior approach due to technical difficulty. The average operating time of the completed endoscopic adrenalectomies was 183 minutes (85-315 minutes) and the average time of the last 8 cases was 148 minutes. There was no operative morbidity or mortality. Immediate mobilization and food uptake was possible on the day of the operation in all cases. Postoperative analgesic injection was needed only one time on the day of the operation in 12 cases and was not needed in 2 cases. The average hospital stay was 4 days after the surgery.

Purpose: This study morphologically compared and analyzed various measurements from initial radiograph and computed tomography scans of posterior malleolar fractures (PMFs) in tibial spiral fractures and ankle fractures. Materials and Methods: The measurements of PMFs in 31 TSFs and 53 AFs were analyzed. PMFs were classified using Bartoníček’s classification. The initial displacement (ID), cross angle (CA), fragment length ratio (FLR), fragment width ratio (FWR), fragment height ratio (FHR), fragment height (FH), sagittal angle (SA), articular step-off (AS), and inter-fragment distance (IFD) were measured. The presence of intercalary fragments and articular incongruity were identified. Results: Bartoníček types 2 and 3 in the AF group, type 3 in the supination-external rotation (SER) group, type 2 in the pronation-external rotation (PER) group, and type 4 in the TSF group accounted for the largest proportion. In the TSF group, the mean ID, FWR, SA, AS, and IFD were significantly smaller than in the AF group (p<0.001, p=0.003, p<0.001, p<0.001, and p<0.001, respectively). The CA, FLR, FH, and FHR were significantly larger than the AF group (p<0.001, p=0.019, p<0.001, and p<0.001, respectively). Conclusion In TSFs, posterior malleolar fragments tend to have longer anteroposterior lengths and heights, but shorter horizontal lengths than AFs. Most have minimal displacement, congruous joint, and no intercalary fragments. Understanding these morphological differences is necessary for the clinical approach to PMFs in TSFs and AFs.

Maternal and child health is an important issue throughout the world. Given their impact on maternal and child health, nutritional issues need to be carefully addressed. Accordingly, the effect of maternal, child, and nutritional disorders on disability-adjusted life years (DALYs) should be calculated. The present study used DALYs to estimate the burden of disease of maternal, neonatal, and nutritional disorders in the Korean population in 2012. For this purpose, we used claim data of the Korean National Health Insurance Service, DisMod II, and death data of the Statistics Korea and adhered to incidence-based DALY estimation methodology. The total DALYs per 100,000 population were 376 in maternal disorders, 64 in neonatal disorders, and 58 in nutritional deficiencies. The leading causes of DALYs were abortion in maternal disorders, preterm birth complications in neonatal disorders, and iron-deficiency anemia in nutritional deficiencies. Our findings shed light on the considerable burden of maternal, neonatal, and nutritional conditions, emphasizing the need for health care policies that can reduce morbidity and mortality.

A 19-year-old man was referred to Seoul National University Dental Hospital for evaluation of a large painless swelling of the left mandibular angle area in August, 1999. The growth had been first noted 6 years ago. He had visited other hospital in 1997. In spite of the treatment given at the hospital, the mass continued to grow rapidly. Conventional radiographs in 1999 showed an expansile, lobulated, and destructive lesion of the left mandibular body. CT scan demonstrated an expansile mass with a corticated margin. Bony septa were seen within the lesion. Internal calcification noted on the bone-setting CT image, and corresponded to the hypointense area in T1-weighted MRI image. MRI clearly delineated the extent of the lesion which had heterogenous intermediate signal intensity in T1-weighted images and heterogenous hyperintense signal intensity in T2-weighted images. The lesion was well-enhanced. Histopathologically, the lesion was completely encapsulated. Multinucleated giant cells were presented in a fibrous background, demonstrating a storiform pattern. Areas of osteoid rimmed by a few osteoblasts were scattered throughout the lesion. Inflammatory cells, blood vessels, and hemosiderin deposition were also shown. CGCG may show lots of internal calcification foci on the CT, and varied signal intensity in MRI. More cases will be needed to understand the features of the CT and MR finding of CGCG.

BACKGROUND: Non-small cell carcinoma (NSCC) has become the leading cause of cancer related death around the world. However, its prognostic factors remain poorly defined. Galectin-3 is an apoptosis related protein and its relationship with various cancers is presently the subject of research. This study was performed to investigate galectin-3 expression in NSCC and its value as a prognostic factor. METHODS: We examined the expression of galectin-3 and bcl-2 in surgically resected, lung NSCC, including 61 squamous cell carcinomas and 41 adenocarcinomas. PCNA staining was also performed. RESULTS: Each type of carcinoma showed cytoplasmic positivity in 18 (30.0%) and 25 (61.0%) cases, respectively. Squamous cell carcinoma showed increased galectin-3 expression in better differentiated tumors, whereas adenocarcinoma didn't show any relationship with the degree of differentiation. The cytoplasmic positivity of galectin-3 in both types of carcinoma was associated with poor prognosis. Bcl-2 expression didn't show any significant relationship with overall survival. Galectin-3 and bcl-2 expressions were positively correlated. However, co-expression of both proteins was not related to prognosis. CONCLUSIONS: These results indicate that galectin-3 expression in NSCC warrants attention as a possible prognostic factor.

OBJECTIVE: The purpose of this study was to investigate the relation between burden of caregivers in patient with dementia and personality trait of caregivers. METHODS: We interviewed 47 patients with dementia and their caregivers. We assessed patient factors with MMSE, Neuropsyhiatric Iventory(NPI), Activities of Daily Living(ADL) and Seoul-Instrumental Activities of Daily Living(S-IADL) scales. Caregiver factors were assessed by Beck Depression Inventory, Eysenck personality questionnaire(EPQ). We used Burden Interview(BI) to measure caregivers' burden. RESULTS: Among patient factors, NPI scores showed positive correlation with Burden Index(BI)(p<0.05). Among the caregiver factors, neuroticism showed positive correlation of marginal significance with Burden Index(BI)(p<0.06). Caregivers' neuroticsm, depressive symptoms and patients' NPI could explain 19% of caregivers' burden. NPI signi- ficantly affected caregivers' burden(beta=0.334, p<0.05) CONCLUSION: In desigining of the psychosocial service for caregivers of dementia, the psersonaly factors of the caregivers should be taken into account.

Cri du Chat syndrome (CdCS) is a chromosomal disease resulting from a deletion on the short arm of chromosome 5. Characteristic features include high pitched cat-like cry, distinguishing facial features, and mental retardation. Some cases have been reported in the Korean literature, but no case reports about the concrete aspects of developmental delay in CdCS patients have been published. Therefore, we report a CdCS patient with developmental delay who was misdiagnosed as fetal alcohol syndrome. The result of the Korean-Child Development Review and Sequenced Language Scale for Infants showed severe developmental retardation, especially in expressive language.

Understanding of morphological structures such as the sphenoid spine and pterygoid processes is important during lateral transzygomatic infratemporal fossa approach. In addition, osseous variations such as pterygospinous and pterygoalar bridges are significant in clinical practice because they can produce various neurological disturbances or block the passage of a needle into the trigeminal ganglion through the foramen ovale. Two hundred and eighty-four sides of Korean adult dry skulls were observed to carry out morphometric analysis of the lateral plate of the pterygoid process, to investigate, for the first time among Koreans, the incidence of the pterygospinous and pterygoalar bony bridges, to compare the results with those available for other regional populations, and to discuss their clinical relevance as described on literatures. The mean of maximum widths of the left and right lateral plates of the pterygoid process were 15.99 mm and 16.27 mm, respectively. Also, the mean of maximum heights of the left and right lateral plates were 31.02 mm and 31.01 mm, respectively. The ossified pterygospinous ligament was observed in 51 sides of the skulls (28.0%). Ossification of the pterygospinous ligament was complete in four sides (1.4%). In 47 sides (16.6%), the pterygospinous bridge was incomplete. The ossified pterygoalar ligament was observed in 24 sides of the skulls (8.4%). Ossification was complete in eight sides (2.8%) and incomplete in 16 sides (5.6%). This detailed analysis of the lateral plate of the pterygoid process and related ossification of ligaments can improve the understanding of complex clinical neuralgias associated with this region.

A 58-year-old male patient with chronic hepatitis B infection and hypertension was referred for the evaluation of a skin rash. The skin biopsy showed multiple hyaline thrombi in small blood vessels, red blood cell extravasation, and epidermal atrophy. The CBC, chemistry, UA, and radiological studies were unremarkable except for elevated AST/ALT on liver function tests. The hepatitis B virus markers were compatible with the diagnosis of acute replicative phase chronic hepatitis B; HBeAg 86,646 cpm (count per minute), anti-HBeAb (-), HBV PCR (Quantitative) >1.10x108 IU/mL, and >640,200,000 copies/mL. Rouleaux formation was seen on the peripheral blood smears. Serum PEP/IEP demonstrated an M-spike (27.53%) in the gamma region and abnormal bowed arcs in IgG, kappa light chain with Cryoglobulin (+), ANCA (+), FANA (-), and rheumatoid factor (-) on the serological test. The percent of plasma cells on the bone marrow biopsy was approximately 15%. Type I cryoglobulinemia is a rare disease that can be associated with hematologic disorders, but smoldering myeloma or/and hepatitis B has not been reported in association with Type I cryoglobulinemia. Here, we report a case of Type I cryoglobulinemia that showed multiple skin ulcers due to vascular occlusion related to the monoclonal cryoglobulin with smoldering myeloma and acutely reactivated chronic hepatitis B.
