Comparison of the Effectiveness of Three Lumbosacral Orthoses on Early Spine Surgery Patients: A Prospective Cohort Study

Objective@#To compare the convenience and effectiveness of the existing lumbosacral orthoses (LSO) (classic LSO and Cybertech) and a newly developed LSO (V-LSO) by analyzing postoperative data. @*Methods@#This prospective cohort study was performed from May 2019 to November 2019 and enrolled and analyzed 88 patients with degenerative lumbar spine disease scheduled for elective lumbar surgery. Three types of LSO that were provided according to the time of patient registration were applied for 6 weeks. Patients were randomized into the classic LSO group (n=31), Cybertech group (n=26), and V-LSO group (n=31). All patients were assessed using the Oswestry Disability Index (ODI) preoperatively and underwent plain lumbar radiography (anteroposterior and lateral views) 10 days postoperatively. Lumbar lordosis (LS angle) and frontal imbalance were measured with and without LSO. At the sixth postoperative week, a follow-up assessment with the ODI and orthosis questionnaire was conducted. @*Results@#No significant differences were found among the three groups in terms of the LS angle, frontal imbalance, ODI, and orthosis questionnaire results. When the change in the LS angle and frontal imbalance toward the reference value was defined as a positive change with and without LSO, the rate of positive change was significantly different in the V-LSO group (LS angle: 41.94% vs. 61.54% vs. 83.87%; p=0.003). @*Conclusion@#The newly developed LSO showed no difference regarding its effectiveness and compliance when compared with the existing LSO, but it was more effective in correcting lumbar lordosis.

Immobilization Effect and Abdominal Pressure of Newly-Developed Lumbosacral Spinal Orthosis during Task Performance

Objective@#We evaluated the efficacy of a newly-developed spinal orthoses (V-LSO) by comparing the stabilizing effect, abdominal pressure, and comfort of 3 different semirigid LSOs (classic LSO, V-LSO, and CybertechⓇ ) during various body movements. @*Methods@#Thirty healthy volunteers (23∼47 years, 24 males, 6 females) were selected. A dual inclinometer measured the range of motion (ROM) while the participants performed flexion/extension and lateral flexion of the lumbar spine with 3 LSOs.The LSO’s pressure on the abdominal surface was measured using 9 pressure sensors while lying, sitting, standing, flexion/extension, lateral flexion, axial rotation, and lifting a box. Comfort and subjective immobilization were analyzed by a questionnaire. @*Results@#V-LSO had a statistically significant effect on flexion over CybertechⓇ . No significant differences were noted during extension and lateral flexion between the 3 LSOs. The abdominal pressure showed no significant differences while supine. While sitting, standing, and lifting a box, the mean abdominal pressure for V-LSO were significantly higher than those for Cybertech Ⓡ . During lumbar flexion, the mean abdominal pressures for classic LSO and V-LSO were significantly higher than that of CybertechⓇ . For extension, lateral flexion and axial rotation, the abdominal pressure for V-LSO was significantly higher than those of classic LSO and CybertechⓇ . In the subjective analysis, V-LSO and CybertechⓇ scored best for comfort. @*Conclusion@#The V-LSO and CybertechⓇ were more comfortable than the classic LSO, and hence, may have improved compliance with decreased discomfort. V-LSO may be superior to the other LSOs in restricting lumbar movement and increasing intraabdominal pressure.

Continuous quality improvement program and its results of Korean Society for Cytopathology

Since 1995, the Korean Society for Cytopathology has overseen the Continuous Quality Improvement program for cytopathology laboratories. The Committee of Quality Improvement has carried out an annual survey of cytology data for each laboratory and set standards for proficiency tests. Methods: Evaluations were conducted four times per year from 2008 to 2018 and comprised statistics regarding cytology diagnoses of previous years, proficiency tests using cytology slides provided by the committee, assessment of adequacy of gynecology (GYN) cytology slides, and submission of cytology slides for proficiency tests. Results: A total of 206 institutes participated in 2017, and the results were as follows. The number of cytology tests increased from year to year. The ratio of liquid-based cytology in GYN gradually decreased, as most of the GYN cytology had been performed at commercial laboratories. The distribution of GYN diagnoses demonstrated nearly 3.0% as atypical squamous cells. The rate for squamous cell carcinoma was less than 0.02%. The atypical squamous cell/squamous intraepithelial lesion ratio was about 3:1 and showed an upward trend. The major discordant rate of cytology-histology in GYN cytology was less than 1%. The proficiency test maintained a major discordant rate less than 2%. The rate of inappropriate specimens for GYN cytology slides gradually decreased. Conclusions: The Continuous Quality Improvement program should be included in quality assurance programs. Moreover, these data can contribute to development of national cancer examination guidelines and facilitate cancer prevention and treatment.

MiR-9 Controls Chemotactic Activity of Cord Blood CD34⁺ Cells by Repressing CXCR4 Expression

Improved approaches for promoting umbilical cord blood (CB) hematopoietic stem cell (HSC) homing are clinically important to enhance engraftment of CB-HSCs. Clinical transplantation of CB-HSCs is used to treat a wide range of disorders. However, an improved understanding of HSC chemotaxis is needed for facilitation of the engraftment process. We found that ectopic overexpression of miR-9 and antisense-miR-9 respectively down- and up-regulated C-X-C chemokine receptor type 4 (CXCR4) expression in CB-CD34⁺ cells as well as in 293T and TF-1 cell lines. Since CXCR4 is a specific receptor for the stromal cell derived factor-1 (SDF-1) chemotactic factor, we investigated whether sense miR-9 and antisense miR-9 influenced CXCR4-mediated chemotactic mobility of primary CB CD34⁺ cells and TF-1 cells. Ectopic overexpression of sense miR-9 and antisense miR-9 respectively down- and up-regulated SDF-1-mediated chemotactic cell mobility. To our knowledge, this study is the first to report that miR-9 may play a role in regulating CXCR4 expression and SDF-1-mediated chemotactic activity of CB CD34⁺ cells.

Effects of Repetitive Transcranial Magnetic Stimulation on Behavioral Recovery during Early Stage of Traumatic Brain Injury in Rats

Repetitive transcranial magnetic stimulation (rTMS) is a promising technique that modulates neural networks. However, there were few studies evaluating the effects of rTMS in traumatic brain injury (TBI). Herein, we assessed the effectiveness of rTMS on behavioral recovery and metabolic changes using brain magnetic resonance spectroscopy (MRS) in a rat model of TBI. We also evaluated the safety of rTMS by measuring brain swelling with brain magnetic resonance imaging (MRI). Twenty male Sprague-Dawley rats underwent lateral fluid percussion and were randomly assigned to the sham (n=10) or the rTMS (n=10) group. rTMS was applied on the fourth day after TBI and consisted of 10 daily sessions for 2 weeks with 10 Hz frequency (total pulses=3,000). Although the rTMS group showed an anti-apoptotic effect around the peri-lesional area, functional improvements were not significantly different between the two groups. Additionally, rTMS did not modulate brain metabolites in MRS, nor was there any change of brain lesion or edema after magnetic stimulation. These data suggest that rTMS did not have beneficial effects on motor recovery during early stages of TBI, although an anti-apoptosis was observed in the peri-lesional area.

Interplay between Intestinal Microbiota and Host Immune System

Whether we are aware or not, diverse microorganisms are living on almost all environmentally exposed surfaces on our body without eliciting harmful immune responses. In fact, recent understanding from numerous studies indicates that our health is highly dependent on the contribution of intestinal commensal bacteria. It appears through its symbiotic interaction with the host, which is the result of millions of years of co-evolution, the microbiota shapes the immune system. In this review, we discuss the relationship between host physiology and commensal bacteria and explore the molecular mechanisms by which the adaptive immune system is influenced by the intestinal microbiota.

An Inverse Relationship between the Expression of the Gastric Tumor Suppressor RUNX3 and Infection with Helicobacter pylori in Gastric Epithelial Dysplasia

BACKGROUND/AIMS: This study was performed to determine the association between RUNX3 expression and Helicobacter pylori infection in premalignant gastric lesions. METHODS: We examined 107 patients with gastric epithelial dysplasia who had undergone endoscopic mucosal resection or submucosal dissection. All tissue samples were evaluated by RUNX3 staining and subclassified by immunophenotype. H. pylori infection in dysplastic lesions and the normal surrounding tissue was examined by silver staining, and cagA status was assessed by polymerase chain reaction. RESULTS: The loss of RUNX3 expression was observed in 62 cases (57.9%), and an association with H. pylori infection was found in 54 cases (50.5%). The infection rate with the cagA-positive H. pylori strain was 63.0%. In RUNX3-negative lesions, the rate of H. pylori infection (p=0.03) and the frequency of category 4 lesions (according to the revised Vienna classification) were high (p=0.02). In addition, the gastric mucin phenotype was predominant. In RUNX3-negative category 4 lesions, the rate of cagA-positive H. pylori infection rate was high but not significantly increased (p=0.08). CONCLUSIONS: Infection with H. pylori is associated with inactivation of RUNX3 in early gastric carcinogenesis. This mechanism was prominent in gastric cancer with a gastric mucin phenotype.

Differential LINE-1 Hypomethylation of Gastric Low-Grade Dysplasia from High Grade Dysplasia and Intramucosal Cancer

BACKGROUND/AIMS: Gastric epithelial dysplasia is considered a precancerous lesion with a variable clinical course. There is disagreement, however, regarding histology-based diagnoses, which has led to confusion in choosing a therapeutic plan. New objective markers are needed to determine which lesions progress to true malignancy. We measured LINE-1 methylation levels, which have been reported to strongly correlate with the global methylation level in gastric epithelial dysplasia and intramucosal cancer. METHODS: A total of 145 tissue samples were analyzed by two histopathologists. All tissues were excised by therapeutic endoscopic mucosal resection and paired with adjacent normal tissue samples. A modified long interspersed nucleotide elements-combined bisulfite restriction analysis (COBRA-LINE-1) method was used. RESULTS: Gastric epithelial dysplasia and intramucosal cancer tissues had significantly lower levels of LINE-1 methylation than adjacent normal gastric tissues. High-grade dysplasia and intramucosal cancer were distinguishable from low-grade dysplasia based on LINE-1 methylation levels. Furthermore, the distinction could be determined with high sensitivity and specificity, as shown by the receiver operating characteristic (ROC) curve (AUC, 0.82; 95% confidence interval, 0.74 to 0.88). CONCLUSIONS: LINE-1 methylation levels may provide a diagnostic tool for identifying high-grade dysplasia and intramucosal cancer.

A Case of Acinar Cell Carcinoma of the Pancreas

Pancreatic acinar cell carcinoma is an uncommon malignancy of the exocrine pancreas. Because of a higher recurrence rate and frequent metastases, this tumor, generally, has a poor prognosis. We report a case of pancreatic acinar cell carcinoma in a 60-year-old man. His chief complaint was jaundice. Abdominal CT revealed a heterogeneous enhancing mass in the pancreatic head measuring 8.2x7.5cm. After receiving the Whipple procedure, acinar cell carcinoma was diagnosed by pathological examination. Liver metastasis was found at one year after the curative resection.

A Cases of Paraganglioma in Bladder of Patient who Visited with Acute Renal Failure / 대한신장학회지

Pheochromocytoma is a catecholamines secreting tumor that usually appears in the adrenal medulla, sympathetic ganglia and extra-adrenal chromaffin tissue. About 10% of this disease is detected in the extra-adrenal chromaffin tissue which is called paraganglioma. The three major clinical symptoms of pheochromocytoma are headache, syncope and hypertension. Approximately 0.1% of hypertensive patients have pheochromocytoma. The extra-adrenal paraganglioma is found in abdominal sympathetic nerve ganglion or Zukerkandle's organ with great frequency, but it also appears, albeit rare, in the cervical ganglion, thoracic cavity, bladder, and pelvic cavity. Some cases of paraganglioma in bladder are being reported internationally, but domestic reports are rare. We report a case of paraganglioma originating in the urinary bladder of patient who visited with acute renal failure associated with malignant hypertension. We treated him with phenoxybenzamine and later with partial cystectomy. High blood pressure was well controlled and acute renal failure was resolved.

Expression of RUNX3 in Human Gastric Cancer

PURPOSE: RUNX3, a novel tumor suppressor, is frequently inactivated in gastric cancer. In the present study, we examined the pattern of RUNX3 expression in gastric cancer cells from gastric cancer specimens and the impact of its alteration on clinical outcome. MATERIALS AND METHODS: A total of 124 samples of both gastric cancer and normal tissue were obtained from 124 patients who underwent curative gastrectomy at the Seoul Medical Center from January 2001 to December 2005. RUNX3 expression was determined by immunohistochemical staining, and the results were analyzed. Statistical analysis wabased on clinicopathological findings and differences in survival rates. RESULTS: The mean age of the patients was 61 years, and the male:female ratio was 1.9:1. The expression rate of RUNX3 was 59.7% (74/124). The expression rate was higher in differentiated gastric cancers (nucleus: 9.1%, cytoplasm: 57.6%) than in the undifferentiated types (nucleus: 5.2%, cytoplasm: 46.6%) (P=0.133). The 5-year survival rates according to RUNX3 expression determined from cancer tissue were 88.9% for the nucleus +/- cytoplasm(+) group of patients, 76.1% for the cytoplasm only (+) group of patients, and 65.3% for the RUNX3 negative expression group of patients (P=0.626). Only UICC TNM staging showed statistical significance related to the survival rate, as determined by multivariate analysis. CONCLUSION: The RUNX3 expression rate was higher in differentiated gastric cancer than in the undifferentiated types without significance. Although RUNX3 expression predicted better survival, based on multivariate analysis, the finding was not statistically significant. More cases should be further evaluated.

Association of NQO1 Polymorphism with Multiple Myeloma Risk in Koreans / 대한진단검사의학회지

BACKGROUND: NAD(P)H:quinone oxidoreductase 1 (NQO1) is an important enzyme in the metabolism of xenobiotics. NQO1 609C -> T (NQO1*2) has been reported to be associated with reduced enzyme activity, benzene-induced hematotoxicity, and acute leukemia. Incidences of multiple myeloma show interethnic variation and exposure to asbestos, petroleum products, and diesel exhaust is a risk factor for multiple myeloma. We studied the associations of NQO1 polymorphism with multiple myeloma risk, stage, and prognostic factors (hemoglobin, calcium, beta2-microglobulin, M-protein and creatinine). METHODS: The frequency of NQO1 polymorphism was investigated in 117 myeloma patients and 166 controls. NQO1 genetic polymorphism was determined by TaqMan allelic discrimination assay. Prognostic factors were obtained from the patients' medical records. RESULTS: The frequencies of the NQO1*1/*1, *1/*2, and *2/*2 genotypes were 31.6%, 63.2%, and 5.1% in the patients, whereas the respective figures in the controls were 31.9%, 48.3%, and 19,9%. The frequency of NQO1*2/*2 was significantly lower in patients than in controls and the odds ratio (OR) was 0.24 (95% confidence interval: 0.01-0.68) to NQO1*1/*1 genotype, indicating a decreased risk for multiple myeloma. There were no significant differences in tumor stages and other prognostic factors among NQO1 genotypes. CONCLUSIONS: A risk for multiple myeloma decreased in NQO1*2/*2 genotype in Koreans. We report, for the first time, that NQO1 polymorphism is associated with multiple myeloma risk.

The Effect of Combined Immunosuppressive Treatment with FK 506-Cyclophosphamide on Surgical Angiogenesis / 대한정형외과연구학회지

PURPOSE: To evaluate the effect of combined immunosuppressive treatment with FK 506-cyclophosphamide on surgical angiogenesis in non-vascularized bone xenografts. MATERIALS AND METHODS: Twenty-seven hamster-to-rat non-vascularized bone xenografts were performed. For surgical angiogenesis, recipient origin saphenous arteriovenous bundles were implanted into the medullary canals of graft bones. Immunosuppression with FK 506-cyclophosphamide was performed in group 1, not in group 2, control group. At postoperative 4 weeks, microangiography with microfil was conducted. Decalcified bones were cleared and the area of newly formed capillary, capillary density, were quantitatively evaluated using Scion image program. Bone specimens stained with hematoxylin-eosin were evaluated histologically also. RESULTS: There was no significant difference of capillary densities between immunosuppressed group and non-immunosuppressed control group (0.37+/-0.03/0.39+/-0.02, P=0.58). On histological examination, both groups showed neoangiogenesis into the medullary canals and endosteal bones. CONCLUSION: FK 506-cyclophosphamide immunosuppression did not suppress the angiogenesis in non-vascularized bone xenografts, FK 506-cyclophosphamide combination of immunosuppression will be useful even in the condition of surgical angiogenesis.

Cases of Pathology-Proven Lung Adenocarcinoma Presenting as Pneumonic Pattern

Lung adenocarcinoma is the cancer originated in terminal bronchiole or alveolar epithelium and its incidence is on the increase. The most common radiologic pattern of lung adenocarcinoma is peripheral nodule or mass, but it can be showed various findings such as hilar mass, consolidation, atelectasis or multicentric lesions. Sometimes it is difficult to differentiate lung adenocarcinoma from other diseases, especially pneumonia. We experienced three patients with lung adenocarcinoma, just only presented as pneumonic consolidation on chest X-ray and CT scan. The clinician should consider seriously lung adenocarcinoma including bronchioloalveolar carcinoma in patients who did not respond to antibiotics. And in such cases, pathologic diagnosis must be perfomed at proper time to confirm disease.

Expression of the Peroxisome-proliferator-activated Receptor-gamma in Human Gastric Cancer

PURPOSE: Recently, interest in peroxisome-proliferator-activated receptors (PPAR) has increased, although clinical studies of the effect of PPAR-gamma expression on gastric cancer have not been reported yet. In this study, we investigated the role of PPAR-gamma expression in gastric cancer patients. MATERIALS AND METHODS: One hundred twenty-eight (128) samples of both gastric cancer and normal tissues were obtained from 128 patients who had undergone at a curative gastrectomy at Seoul Medical Center from Jan. 2001 to Dec. 2005. PPAR-gamma expression was determined by using immunohistochemical staining, and the results were analyzed. The statistical analysis was based on clinicopathological findings and the differences in survival rates. RESULTS: The mean age of the patients was 61, and the male:female ratio was 1.9:1. PPAR-gamma expression was significantly higher in cancer tissues than in normal tissue (81.3% vs. 57.0%, P<0.001). There was insignificant difference between well and moderately differentiated types and poorly differentiated types in terms of the expression of PPAR-gamma (87.0% vs. 74.6%, P=0.074). In the univariate analysis the survival rate was significantly increased when PPAR-gamma was expressed in normal tissue (P=0.003). In the multivariate analysis, only the UICC TNM staging had significance related to the survival rate. CONCLUSION: The rate of PPAR-gamma expression was higher in cancer tissue than it was in normal tissue from gastric cancer patients. In the univariate analysis, PPAR-gamma expression in normal tissue had significance with respect to survival, but the multivariate analysis showed no such significance. Thus, we should further evaluate more cases to determine whether or not such a significance exists.

Changes in serum and dialysate levels of Cancer Antigen 125 (CA125) in continuous ambulatory peritoneal dialysis patients / 대한내과학회지

BACKGROUND: Peritoneal mesothelial cells are the most important intraperitoneal cells quantitatively and have the capability to secret different types of substances. It may therefore be essential to have information on the mesothelial cell mass during peritoneal dialysis. Cancer Antigen 125 (CA125) is a 22KDa glycoprotein which is a clinically useful tumor marker of non-mucinous epithelial ovarian carcinoma. Recently, other cells including pleural and peritoneal mesothelial cell have been proved to express CA125. This study was undertaken to determine whether CA125 can be used as a marker of mesothelial cell mass in clinically stable 39 CAPD patients. METHODS: We checked serum and peritoneal dialysate CA125 level, D/P creatinine and D/Do glucose after 4 hours dwell in 39 stable continuous ambulatory CAPD patients. RESULTS: No statistically significant correlation was seen among the patient's age, sex, serum and dialysate levels of CA125. The dialysate CA125 levels correlated with the duration of CAPD, negatively (r=-0.345, p=0.039) and a significant positive correlation was seen between the duration of CAPD and D/Do glucose at 4 hours (r=0.523, p=0.001). But there were not a correlation between the dialysate CA125 levels and D/P creatinine after 4 hours dwell nor between the dialysate CA125 levels and D/Do glucose after 4 hours dwell. CONCLUSION: Although the duration of CAPD affects CA125 levels in dialysate, no specific alteration in peritoneal membrance transport properties can be detected or predicted by changes in dialysate concentration of CA125. However longitudinal follow-up of changes in concentration of dialysate CA125 may be useful in evaluating mesothelial cell mass in stable CAPD patients.Department of Internal Medicine, Chonnam National University Medical School, Gwangju, Korea.

A Case of Wernicke's Encephalopathy Associated with Hyperemesis Gravidarum / 영남의대학술지

Wernicke's encephalopathy is an acute-onset illness characterized by mental confusion, ataxia and ophthalmoplegia due to a thiamine deficiency. Immediate administration of thiamine prevents progression of the disease and reverses brain lesions. We have experienced a case of Wernicke's encephalopathy associated with hyperemesis gravidarum. As Wernicke's encephalopathy is mostly associated with chronic alcoholism, the possibility of Wernicke's encephalopathy may be ignored in young women. We emphasize the need for thiamine supplementation in the patient requiring intravenous alimentation such as hyperemesis gravidarum.

Neuro-Behcet's Disease Presented with Cerebral Venous Sinus Thrombosis: A Case Report / 영남의대학술지

Behcet's disease is a chronic, relapsing multisystem disorder, that may develop into variable neurological manifestations. They include vascular and parenchymal involvement. Vascular involvement is dominated by cerebral venous sinus thrombosis marked by benign intracranial hypertension. Cerebral venous sinus thrombosis can present with all the classical criteria for idiopathic intracranial hypertension, including normal brain CT findings with normal CSF content. But brain MRI is a useful diagnostic method in this situation to confirm the presence of cerebral venous sinus thrombosis. We experienced a case of raised intracranial pressure in a 21-year-old man, caused by cerebral venous sinus thrombosis. We disclosed his symptoms and signs thus fulfilling the diagnostic criteria for Behcet's disease.
