ABSTRACT

BACKGROUND AND OBJECTIVES: Intravenous immunoglobulin-SN (IVIG-SN) is a new human immunoglobulin product. Its safety is ensured by pathogen-elimination steps comprising solvent/detergent treatment and a nanofiltration process. This multicenter clinical study was designed to evaluate the efficacy and safety of combined aspirin and high-dose IVIG-SN therapy in pediatric patients with Kawasaki disease (KD). SUBJECTS AND METHODS: We evaluated coronary artery lesions (CALs) at 2 and 7 weeks after administering IVIG-SN; total fever duration; and variations in erythrocyte sedimentation rate, N-terminal pro B-type natriuretic peptide or B-type natriuretic peptide, and creatine kinase-myocardial band level before and after treatment with IVIG-SN (2 g/kg). Adverse events were monitored. RESULTS: Forty-five patients were enrolled, three of whom were excluded according to the exclusion criteria; the other 42 completed the study. The male:female ratio was 0.91:1, and the mean age was 29.11±17.23 months. The mean fever duration before IVIG-SN treatment was 6.45±1.30 days. Although most patients had complete KD (40 patients, 90.91%), four had atypical KD (9.09%). After IVIG-SN treatment, one patient (2.38%) had CALs, which was significantly lower than the incidence reported previously (15%) (p=0.022), but not significantly different from recent data (5%). There were no serious adverse events, though 28 patients (63.64%) had mild adverse events. Three adverse drug reactions occurred in 2 patients (eczema, anemia, and increased eosinophil count), all of which were transient. CONCLUSION: IVIG-SN treatment in patients with KD was safe and effective.

ABSTRACT

BACKGROUND AND OBJECTIVES: As most dizziness symptoms are vaigue, and misdiagnosis of central dizziness can be life threatening, diagnosis of the dizziness is difficult. Especially, in the emergency room with a restricted environment, it must be more difficult. The aim of this study is to find out and correct the aspects requiring a modification for diagnosis in patients of dizziness who visited emergency room. MATERIALS AND METHODS: The authors retrospectively have reviewed the charts of 458 patients with dizziness who visited the emergency room at Hanyang University Guri Hospital from April 2008 to March 2009 and researched the various informations such as diagnosis, clinical feature, physical findings, present illness, past history, consulted department, and visiting season, etc. RESULTS: The average age of patients was 61 years old. Even though there was a difference at the diagnosis distribution between age groups, non specific dizziness and benign paroxysmal positional vertigo was the most frequent diagnosis. Checking the dizziness characters like whirling sense, autonomic symptoms and progressing features was important. And vestibular function tests such as nystagmus test and rotatory test like post head shaking or head thrust test were helpful for differential diagnosis of dizziness in emergency room. Patients with central vertigo were older (71.2 year) and had more past medical histories. But there was no seasonal frequency difference of dizziness. CONCLUSION: As at emergency room, the differential diagnosis of dizziness is important but difficult, integrated medical knowledge of several departments associated with dizziness is required.

ABSTRACT

BACKGROUND AND OBJECTIVES: Thyroidectomy for Graves' disease is a rapid, safe, highly successful treatment modality. Also thyroidectomy allows pathological examination for diagnosis of suspected cancer. However, the extent of thyroidectomy in Graves' disease is still controversial. The aim of this study is to evaluate the appropriate surgical extent by comparing the postoperative outcomes of two groups of patients with Graves' disease who underwent total or less than total thyroidectomy. SUBJECTS AND METHOD: We carried out a retrospective review of 33 patients who underwent thyroidectomy for Graves' disease from January 2001 to December 2010. We investigated the postoperative thyroid hormone function and complication rate according to the extent of thyroidectomy. RESULTS: Among the 33 patients with Graves' disease, 19 patients underwent total thyroidectomy, six patients bilateral subtotal thyroidectomy (BST) and eight patients lobectomy and contralateral subtotal lobectomy (LCSL). Postoperative hypothyroidism, euthyroidism, and hyperthyroidism occurred in 27 (81.7%), 2 (6.1%) and 4 (12.2%) patients, respectively. Postoperative recurrent hyperthyroidism was observed in 2 (33.3%) patients of BST and in 2 (25.0%) of LCSL. One patient was found with permanent hypoparathyroidism, and two with transient vocal cord paralysis. According to histopathologic report, nine patients were accompanied with thyroid cancer. CONCLUSION: Thyroidectomy for Graves' disease has high success rate, low recurrence rate and low complication rate. In terms of surgical extent, total thyroidectomy is a more appropriate procedure because of its low recurrence of hyperthyroidism.

ABSTRACT

Frontal sinusitis can cause an intractable frontal headache. Frequently, the external approach is performed for a lesion located in the lateral aspect of the frontal sinus. This area is considered to be "out of reach" for standard endoscopic instruments. However, problems such as scars can be a serious handicap of the external approach for patients with cosmetic concerns. We experienced a case of lateral frontal sinusitis associated with an intractable frontal headache, which was successfully treated via endoscopic sinus surgery aided by sagittal CT and intraoperative C-arm using K-wire instead of the external approach.

ABSTRACT

Gossypiboma refers to a mass resulting from a retained gauze pad accidentally left within the body after surgery. Although the clinical features are diverse, it is often found incidentally as a mass having an internal cystic change and adhesion to adjacent organs. Abdominal computed tomography (CT) is helpful, yet the initial diagnosis can be misleading in cases with atypical findings. We report a case of gossypiboma in a 78-year-old woman that we suspected was a gastrointestinal stromal tumor according to abdominal CT and endoscopic ultrasound, yet was diagnosed as a gossypiboma postoperatively.

ABSTRACT

BACKGROUND AND OBJECTIVES: Voltage dependent calcium channel (VDCC) mediates calcium ion influx and controls neurotransmitter release in excitable cells. Hair cells in vertebrates cochlea are known to express L-type VDCC. The purpose of this study was to measure calcium current from hair cells to investigate basic activity and characteristics of VDCC. MATERIALS AND METHOD: We measured calcium current in hair cells of the chicken's auditory organ, the basilar papilla analogous to the mammalian cochlea, in whose L-type, dihydropyridinesensitive calcium channels predominate and in vestibular hair cells from cristae. Calcium currentthrough VDCC was isolated in voltage-clamp recording using Cesium, Tetraethylammonium, 4- aminopyridine and apamin to block the much larger potassium currents. Various concentrations of internal calcium buffer, ethylene glycol tetraacetic acid (EGTA) or 1,2-bis (o-aminophenoxy) ethane-N,N,N',N'-tetraacetic acid (BAPTA) were used. RESULTS: The higher the buffer concentration, the larger the current size were ; they were significantly larger in 10 mM of calcium buffer concentration (ANOVA, p< 0.05). There was no difference in calcium current between cochlear and vestibular hair cells. CONCLUSION: We could successfully isolate stable inward calcium current from chick hair cells. This experiment can be used as a basic method to understand neurotransmission process between hair cells and afferent neurons.

ABSTRACT

Right atrial aneurysm is a rare abnormality of unknown origin. Approximately half of patients with right atrial aneurysm show no symptoms. Right atrial aneurysm is usually detected by chance at any time between fetal and adult life and can be associated with atrial arrhythmia and systemic embolism. The diagnosis of right atrial aneurysm can be established with echocardiography, computed tomography (CT) or magnetic resonance imaging (MRI). Because of thromboembolic risk, aneurysmectomy is usually recommended. We review the case report of a 69-year-wold woman with right atrial appendiceal aneurysm, whose diagnosis was established by echocardiography and CT angiography.

ABSTRACT

mutation at position 3,243 in the mtDNA-encoded tRNALeu (UUR) gene is associated with the syndrome of maternally inherited diabetes and deafness (MIDD). It is a rare form of diabetes first described in 1992 characterized by maternal relatives with an early middle-aged onset of diabetes, bilateral sensorineural hearing loss, and a normal or low body mass index. A 37-year-old woman was admitted because of general weakness. She had diabetes mellitus (DM) and deafness. Her mother had DM, her second sister had DM and deafness, and her little brother had DM. The molecular genetic analysis identified the A3243G point mutation. In addition, rhabdomyolysis was diagnosed based on the initial laboratory findings and a whole-body bone scan. We report a case of MIDD with rhabdomyolysis due to a low carbohydrate intake and present it with a literature review.

ABSTRACT

BACKGROUND: Foot-and-mouth disease virus (FMDV) is a small single-stranded RNA virus which belongs to the family Picornaviridae, genus Apthovirus. It is a principal cause of FMD which is highly contagious in livestock. In a wild type virus infection, infected animals usually elicit antibodies against structural and non-structural protein of FMDV. A structural protein, VP1, is involved in neutralization of virus particle, and has both B and T cell epitopes. A RNA-dependent RNA polymerase, 3D, is highly conserved among other serotypes and strongly immunogenic, therefore, we selected VP1 and 3D as vaccine targets. METHODS: VP1 and 3D genes were codon-optimized to enhance protein expression level and cloned into mammalian expression vector. To produce recombinant protein, VP1 and 3D genes were also cloned into pET vector. The VP1 and 3D DNA or proteins were co-immunized into 5 weeks old BALB/C mice. RESULTS: Antigen-specific serum antibody (Ab) responses were detected by Ab ELISA. Cellular immune response against VP1 and 3D was confirmed by ELISpot assay. CONCLUSION: The results showed that all DNA- and protein-immunized groups induced cellular immune responses, suggesting that both DNA and recombinant protein vaccine administration efficiently induced Ag-specific humoral and cellular immune responses.

ABSTRACT

Blue rubber bleb nevus syndrome is a rare disorder that's characterized by multiple venous malformations of the skin and gastrointestinal tract, and these lesions usually cause episodes of occult gastrointestinal hemorrhage and iron deficiency anemia. We report here on a case of a 57-year-old woman who presented with intermittent melena and multiple cutaneous venous malformations. The endoscopic and radiologic examinations show multiple bluish polypoid venous malformations on the gastrointestinal tract, retroperitoneum, liver, mediastinum and lung. We were able to diagnose her as suffering from blue rubber bleb nevus syndrome and we treated her with iron supplementation for anemia. We report this case along with a brief review of the relevant literature.

ABSTRACT

The ingestion of foreign bodies into the gut is rather common. Most these foreign bodies are passed out spontaneously without complications. Our patient was hospitalized for fever, nausea and vomiting for one week. On the initial endoscopic examination, a toothpick was seen to be impacted in the wall of the duodenal bulb. Air bubbles were noted at the site where the toothpick was removed. The duodenal perforation was treated with endoscopic hemoclipping. Abdominal CT showed free air in the periduodenum and there was a liver abscess. Therefore, liver abscess associated with duodenal perforation by the toothpick was diagnosed. On the cytology of the aspirated materials from the liver abscess, sulfur granule formation was noted and hepatic actinomycosis was diagnosed. The liver abscess was successfully treated with CT-guided abscess drainage and antibiotics. We report here on an unusual case of a liver abscess associated with duodenal perforation by a toothpick, along with a review of the literature.

ABSTRACT

OBJECTIVE: The purpose of this study was to define the normal variation of fetal heart rate (FHR) and to analyze whether first-trimester fetal heart rate (FHR) are useful in predicting pregnancy outcome. METHODS: We prospectively studied 162 singleton pregnancies with gestational ages ranging from 5 to 10 weeks between Mar. 1999 and Jan. 2003 visting our hospital. Color doppler sonography was used to calculate the fetal heart rate in beats per minute as the mean of 3 waves. RESULTS: The following results were obtained. 1. Overall, 149 pregnancies reached viability and 13 resulted in fetal loss before 13 weeks' gestation. 2. A significantly higher number of viable pregnancies, compared with fetal losses, had FHR within one (73.1% compared with 38.5%, p<0.001) and two (94.6% compared with 69.2%, p<0.001) standard deviations of the mean for viable pregnancies at corresponding gestational ages. 3. A significant correlation was seen between gestational age and fetal heart rate (p<0.001). The regressing equation for heart rate was as follows: heart rate = 3.40 X gestational age (days)-30.15 (r = 0.87). 4. There was no significant difference in the fetal heart rates between male and female embryos during this early stage of pregnancy. CONCLUSION: First-trimester FHR can be helpful to predict pregnancy outcome. Women with FHR outside the reference range from the mean for viable pregnancies at corresponding gestational ages may be at risk for eventual pregnancy loss.

ABSTRACT

OBJECTIVE: Recently, with rising rates of repeat cesarean sections, enormous amount of the studies about trial of labor after cesarean section have been reported to decrease the rate of cesarean section. The purpose of this study is to provide data regarding the safety and the successful prognostic factors of VBAC (vaginal birth after cesarean section). METHODS: This retrospective study was performed based on 194 pregnant women who tried vaginal delivery after cesarean section at Eulji University Hospital from March 1997 to February 2002. The age of mother, gestational age, estimated fetal body weight by ultrasonography, neonatal body weight, cervical effacement, cervical dilatation, Bishop score, the number of previous vaginal delivery, and spontaneous labor were analyzed between successful group (177 patients) and failure group (17 patients) with trial of labor. Student T-test and Chi-square test were used for statistical analysis. RESULTS: 177 cases (91.24%) in 194 cases succeeded in VBAC and 17 cases (8.76%) failed. There was no maternal death or uterine rupture in the cases of trial of labor. The gestational age, estimated fetal body weight by ultrasonography, neonatal body weight, cervical effacement, cervical dilatation, Bishop score, the number of previous vaginal delivery, spontaneous labor had notable differences between the successful group and the failure group. But, There was no significant difference in maternal age. CONCLUSION: The trial of labor after cesarean section is relatively safe method of delivery if it is performed under strict indication. Above findings can be used as possible prognostic factors for the success of VBAC and may reduce the risk and complication of VBAC. The following studies with large populations and performed by multi-centers will be needed for the evaluation of safety and successful prognostic factors of VBAC.

ABSTRACT

OBJECTIVE: Computerized tomography(CT) and magnetic resonance imaging(MRI) are very useful in detection of structural change in the brain including tumors. However, they can not inform functional and biological behavior of such lesions. 99m Tc-Methoxyisobutyl isonitrile(MIBI) is considered as a substrate for MDR1 gene-encoded permeability glycoprotein(P-gp) and it has been used in the evaluation of multidrug resistance(MDR) in various tumors. The purpose of the study is to demonstrate the presence of MDR in brain tumor and brain tumor grading by an external imaging with 201Thallium and 99m Tc-MIBI SPECT. METHODS: 201Thallium and 99m Tc-MIBI SPECT were performed in 18 patients with malignant tumors and in six patients with benign tumors. Immunohistochemical staining(IHC) of the tumor specimen for P-gp was also performed. The histologic grading of the tumors and immunohistochemical staining for P-gp were compared to the dual brain SPECT findings of 201Thallium and 99m Tc-MIBI SPECT studies. Brain tumor with positive 201Thallium SPECT and negative 99m Tc-MIBI SPECT is considered to be multidrug resistance. An uptake index obtained from brain SPECT was used for tumor grading. MDR1 gene-encoded P-gp was assessed by immunohistochemical staining using a monoclonal antibody for P-gp. RESULTS: The malignant group showed significantly higher uptake indices in the 201Thallium and 99m Tc-MIBI SPECT than benign group. The uptake index of 99m Tc-MIBI SPECT was inversely correlated with P-gp immunohistochemical staining without statistical significance. CONCLUSION: 201Thallium and 99m Tc-MIBI SPECT are useful for predicting histologic grade of brain tumors, and 99m Tc-MIBI SPECT might be useful for predicting the presence of MDR protein.

ABSTRACT

PURPOSE: To analyze the results and complications arising from 1,000 cases of primary total knee arthroplasty (TKRA), as performed by one surgeon. MATERIALS AND METHODS: From February, 1992 to June, 2000, 1,000 cases of primary TKRA were performed by a single surgeon. Among the 1,000 cases, 573 cases followed up for more than one year (average 2.9 years) were evaluated try allocating special surgery (HSS) scores and by determining the range of motion (ROM), and presence of complications retrospectively. RESULTS: There were 872 cases of primary osteoarthritis, 70 cases of rheumatoid arthritis, 32 cases of osteonecrosis, and 26 cases of miscellaneous diseases. The HSS score increased from 57.8 preoperatively to 90.4 postoperatively, ROM increased from 111degrees to 113degrees and flexion contracture decreased from 9degrees to 2degrees, but no statistical differences in results were observed between diseases. Common causes of complications were superficial infection (3.6%), deep infection (2.4%) and deep vein thrombosis (1.8%). Two patients died, one due to myocardial infarct and the other due to an unknown etiology. Revision arthroplasties were performed in 19 cases. CONCLUSION: After primary TKRA, ROM and functional score improved satisfactorily. No statistical differences were apparent between diseases. Infection was the most common complication.

ABSTRACT

PURPOSE: To investigate the causes and to determine the most useful test for the early diagnosis of infected TKRA, and to present the treatment modality and its possible complications. MATERIALS AND METHODS: We reviewed 17 cases, with follow up, among the 18 infected TKRA cases registered from March 1992 to June 2000. Diagnosis of deep infection after TKRA was made by assessing clinical symptoms, laboratory and radiological findings, nuclear scan studies and aspirate culture results. Data were analyzed clinically by HSS score, recurrence of infection and postoperative complications. RESULTS: The overall incidence of deep infection after TKRA was 1.4%. In fourteen of the 17 cases TKRA was revised. In 13 cases, excluding 1 case of infection recurrence after 2-stage TKRA revision, the mean ROM increased from 55o to 86o and the mean HSS score increased from 53 points to 84. Knee fusion was performed in 4 cases, including one case of infection recurrence after 2-stage TKRA revision. CONCLUSION: The most reliable clinical results were achieved after a 2-stage TKRA revision. Knee joint fusion should be considered when the general condition is poor, with an initial diagnosis of infection, and in the presence of skin problems.

ABSTRACT

Endothelin derived from the endothelial cells of microvessel is a potent vasoactive peptide, which has various physiologic actions in many internal organs. The fact that endothelin receptors are present on the osteoblastic cells suggests that endothelin play a role in bone metabolism. This study was done to study the effect of endothelin-1 on osteoblast and the combined effect of dexamethasone and endothelin-1 on osteoblast. Human osteoblasts isolated from ilium were cultured in DME/F12 medium, and divided into 5 groups; Group 1 (control), Group 2(10(-7)M endothelin-1), Group 3(10(-7)M endothelin-1+1:2500 monoclonal antibody), Group 4(10(-7)M dexamethasone+10(-7)M endothelin-1), and Group 5(10(-7)M dexamethasone). [3H]-thymidine uptake in groups was 23373.2+/-2722.4 cpm/well, significantly higher than that of control (P<0.05), and the increase was blocked by the addition of monoclonal antibody to endothelin(group 3). [3H]-thymidine uptake in groups adding steroid with or without endothelin was significantly lower than that of other groups (P<0.05). Group 2 showed marked increase in type I procollagen mRNA compared with other groups, but group 3 and 4 showed no significant effect on the expression of type I procollagen mRNA. In histochemical staining for alkaline phosphatase activity, the cells in groups with steroid were strongly positive in staining, large in size and looked well differentiated. Osteocalcin synthesis was also increased in groups with steroid treatment compared with other groups. This study demonstrated that endothelin-1 stimulated DNA synthesis and the expression of type I procollagen mRNA in human osteoblasts, and inhibited alkaline phosphatase activity, but had no significant effect on osteocalcin. Dexamethasone stimulated alkaline phosphatase activity and osteocalcin synthesis, and inhibited DNA synthesis but had no significant effect on the expression of type I procollagen mRNA. Dexamethasone masked the effect of endothelin-1 on human osteoblastic cells, and the effect of dexamethasone was predominant in the group of a combination of endothelin-1 and dexamethasone.

ABSTRACT

Actinomycosis with spinal involvement is very rare. We report a case of spinal actinomycosis with symptoms of spnal cord compression. A 55-year-old women had quadriparesis without evidence of systemic infection. In MRI findings, perivertebral granulomaous mass was compressing the sipinal cord at the level of first thoracic sipine with the signal change of cord and bony destruction. The patient was treated with two-staged opreations, antibiotics and rehabilitation training. She has improved neurologically and also in general condition. Due to rarity of incidence of entity, we reviewed the pertinent literature with discussion of diagnosis, treatment and the prognosis of this disease.
