ABSTRACT

Ethylene glycol is a widely used and readily available substance. Ethylene glycol ingestion does not cause direct toxicity; however, its metabolites are highly toxic and can be fatal even in trace amounts. Poisoning is best diagnosed through inquiry, but as an impaired state of consciousness is observed in most cases, poisoning must be suspected when a significantly elevated osmolar gap or high anion gap metabolic acidosis is found in blood tests. Hemodialysis and alcohol dehydrogenase inhibitors such as ethanol and fomepizole are a part of the basic treatment, and timely diagnosis and treatment are crucial because any delays can lead to death. However, there are few reported cases in Korea, and no report on the use of fomepizole. Herein, we report a case of acute renal failure caused by ethylene glycol poisoning that was treated with fomepizole and hemodialysis and present a literature review.

ABSTRACT

Mycobacterium avium complex (MAC) comprises M. intracellulare and M. avium. MAC usually causes pulmonary diseases in individuals with intact immunity, disseminated disease in patients with acquired immunodeficiency syndrome, and cervical lymphadenitis. It can also cause cutaneous disease, but musculoskeletal infection is rare. Herein, we present a case of vertebral osteomyelitis due to M. intracellulare in an elderly immunocompetent patient who underwent vertebroplasty. The patient was successfully treated with antimycobacterial drugs without surgical intervention. MAC should be considered as a causative pathogen of vertebral osteomyelitis when the patient has a history of vertebroplasty.

ABSTRACT

Staphylococcus lugdunensis is a coagulase-negative staphylococcus. However, it causes various clinically important human infections and behaves similar to Staphylococcus aureus. S. lugdunensis reportedly causes infective endocarditis, skin and soft tissue infection, bone and joint infection, septicemia, endarteritis, urinary tract infection, ocular infection, and peritonitis. There are no reports of septic arthritis by this organism in Korea. We presented a case of septic arthritis due to S. lugdunensis in an elderly patient with diabetes mellitus after an intra-articular injection.

ABSTRACT

Good's syndrome is the rare association of immunodeficiency with thymoma, characterized by hypogammaglobulinemia, depleted B-cells, diminished T-cells and inversion of the CD4/CD8 ratio. Thymectomy does not usually improve hypogammaglobulinemia; thus, the patient remains prone to infections. Infections affect primarily the sinopulmonary and gastrointestinal system. Here we present a case of a 71-year-old woman with common manifestations of Good's syndrome who succumbed to disseminated tuberculosis. Serum immunoglobulin levels should be measured for patients with thymoma and susceptibility to infection.

ABSTRACT

<p><b>INTRODUCTION</b>The treatment of tendinosis of elbow can be challenging, yet rewarding. Nevertheless, for the patients who failed conservative management and develop persistent recalcitrant symptoms, surgical intervention should be considered. The hypothesis of this study is iliac bone marrow plasma injection after arthroscopic debridement of degenerative tissue will bring along biological cure. Thus, it will not only reduce pain but also improve function in patients with resistant elbow tendonitis.</p><p><b>MATERIALS AND METHODS</b>Twenty-four patients (26 elbows) with significant persistent pain for a mean of 15 months, despite of standard rehabilitation protocol and a variety of other nonsurgical modalities were treated arthroscopically. We applied autologous iliac bone marrow plasma injection following arthroscopic debridement. This material is produced by centrifugation of iliac bone marrow blood at 1,800 rpm for 20 to 30 minutes. Patients were allowed full range of motion (ROM) exercise after 2 to 3 days. Cytokine analyses for this injective material were done. Outcome was rated by postoperative sonography, visual analog pain scores (VAS) and Mayo elbow performance scores (MEPS) at 8 weeks and 6 months follow-up. Informed consent had been obtained from the subjects, and the study protocol was approved by the ethics committee of Chosun University Hospital, Korea.</p><p><b>RESULTS</b>All patients in this study noted improvement both in their VAS and MEPS. No complication occurred in any patient. Evidence of tendon healing was observed in postoperative sonographic examination. Predominant cytokines of this study were interleukin-12 (IL-12), interferon-gamma-inducible protein-10 (IP-10) and RANTES.</p><p><b>CONCLUSION</b>Biologic treatments in orthopaedics are just beginning to evolve. In the present investigation, the injection of iliac bone marrow plasma after arthroscopic debridement in severe elbow tendinosis demonstrated early recovery of daily activities and clear improvement.</p>

ABSTRACT

BACKGROUND AND OBJECTIVES: We designed this study to determine the therapeutic potentials of umbilical cord blood (UCB)-mesenchymal stem cells (MSCs), as compared with bone marrow (BM)-MSCs. MATERIALS AND METHODS: MSCs were isolated from UCB and BM. For the in vivo study, myocardial infarction was induced by ligation of the left anterior descending coronary artery (LAD) in rats for 30 min, and this was followed by release; the MSCs were then injected into a designated point around the infarcted area. Echocardiographs were performed two weeks after surgery. For the in vitro study, a cDNA microarray and cytokine array were performed to compare the MSCs from UCB and from BM. Cell migration was assessed by a wound scratch assay, and the level of cardiac ankyrin repeat protein (CARP) was determined by reverse transcriptase-polymer chain reaction (RT-PCR) or Western blot analysis. RESULTS: For the echocardiograph findings, the fractional shortening (FS) was 43.9% in the UCB-MSCs group and it was 38.6% in the BM-MSC group. The ejection fraction (EF) was 79.8% in the UCB-MSC group and it was 72.4% in the BM-MSC group (control FS: 26.2% and the control EF: 56.6%). CARP was one of the highly expressed genes in the UCB-MSCs on the cDNA microarray. The mRNA and the expressed level of CARP protein in the UCB-MSCs were higher than those in the BM-MSCs. The cell migration of the CARP small interfering ribonucleic acid (siRNA) transfected UCB-MSCs was delayed compared to that of the normal UCB-MSCs (p<0.05) CONCLUSION: Our study directly compared the two types of MSCs from UCB and BM, and we suggest that the CARP molecule might be responsible for the motility of UCB-MSCs.

ABSTRACT

Two sources of adult stem cells that have aroused great interest are human bone marrow-derived mesenchymal stem cells (hMSCs) and human umbilical cord blood cells. hMSCs have been reported to maintain their ability to differentiate into neuronal lineage cells in the central nervous system. Therefore, transplantation of hMSCs represents an attractive new form of cellular therapy for clinical application in spinal cord injury (SCI). The aim of this study was to investigate how transplanted hMSCs from the venous circulation moved into a target zone of compression injury in the spinal cord of rats, and if they ameliorated the behavioral impairments associated with SCI. SCI in rats was induced by compressing the spinal cord for 30 s with an aneurysm clip. hMSCs labeled with cholera toxin subunit B conjugated to fluorescein isothiocyanate (CTX B-FITC) were injected intravenously through the tail vein or directly on the SCI site using a 27-g needle. Suspensions of hMSCs collected from adult humans were delivered at concentrations (1x10(6)cells/200 microliter) in 1 or 5 d after experimental SCI. After transplantation of hMSCs, the SCI regions displayed some endogenous background fluorescence, but CTX B-FITC-labeled hMSCs were clearly identifiable. They were observed in injured but not in intact areas; they were usually round or slightly elongated with a prominent nucleus. Only a few hMSCs were found in the spinal cord in each case but there were more cells in the rats injected at day one than at day five. This study confirmed that these were indeed transplanted hMSCs using antisera recognizing human-specific nuclei or human-specific mitochondria. Double immunofluorescence analysis showed the production of some neuronal and glial cell markers in the SCI lesions. Behavioral test scores of SCI rats treated with hMSCs at day one were significantly better than those for rats treated at day five and for the untreated SCI group. Thus, hMSCs appear to be beneficial in reversing the behavioral effects of SCI in this rat model, even when infused one day after injury. They might be a viable source of stem cells for the treatment of human neurological disorders.

ABSTRACT

BACKGROUND: Propofol is an alternative to thiopental as an intravenous induction agent for cesarean section. It is also used as a sedative for supplementation of regional blockade during cesarean section. It has been reported that propofol relaxes not only vascular smooth muscle but also other smooth muscles. The aim of this study was to investigate the effect of propofol on rat uterine smooth muscle in an isolated preparation in the rat. METHODS: Uterine smooth muscle tissues were obtained from rats (n = 21). The muscle strips were suspended in tissue baths and isometric tension was recorded. After spontaneous or oxytocin induced activity had been accomplished in the buffer solution as a control, propofol (1 to 20microgram/ml) in fat emulsion was applied cumulatively to the bath and the effects were continuously recorded. RESULTS: In vitro, propofol induced a dose-dependent inhibition of spontaneous as well as oxytocin induced myometrial contractile activity. Propofol concentration of 1microgram/ml had no significant effects on the resting tension, active tention, and frequency of contraction developed by spontaneous and oxytocin induced uterine contractility. However, Complete muscular relaxations on spontaneous and oxytocin induced contractility were obtained at a concentration of 10microgram/ml and 20microgram/ml, respectively. CONCLUSIONS: Propofol inhibits spontaneous and oxytocin-induced uterine smooth muscle contractions in dose dependent pattern.

ABSTRACT

Benign or malignant tumors that arise in a benign cystic teratoma are rare. Malignant transformation in mature cystic teratoma of ovary is reported to occur in 1~3%. Several types of malignancy can occur from any of three germ-cell layers, but the most common malignancy is a squamous cell carcinoma derived from ectoderm. We experienced a papillary carcinoma arising in a struma ovarii of the complex teratoma. 74-year-old female presented with an abdominal discomfort. A pelvic ultrasonograph and computed tomography detected a 7 x 6 cm-sized and well-circumscribed cystic mass at the anterior to the uterus. The inner part of the mass was filled with cystic fluid showing low-density, however, solid portion including fat and soft tissue accompanied by calcification was identified in more than half of the entire tumor volume. The patient underwent a bilateral salpingo-oophorectomy. On histopathologic examination, the lesion was consistent with papillary carcinoma with squamoid features arising in a struma ovarii of the mature cystic teratoma. We herein report a case of the very rare papillary carcinoma arising in a struma ovarii of the complex teratoma and review the available literature.

ABSTRACT

PURPOSE: The aim of the this study was to evaluate the effect of various perinatal conditions on TSH and thyroid hormone levels in cord blood. METHODS: Cord blood samples were collected from 130 neonates immediately after birth. TSH, T3, and free T4 levels were measured by the radioimmunoassay(RIA) method. The effects of gestational age, sex, birth weight, delivery method, perinatal asphyxia, maternal diabetes mellitus(DM), and preeclampsia on TSH and thyroid hormone levels were assessed by ANOVA test, Student t-test, and multiple regression analysis. RESULTS: Birth weight and sex did not affect TSH and thyroid hormone levels. TSH level increased according to gestational age(P<0.05). TSH level was 4.42+/-0.66 microIU/mL in infants born vaginally, which was higher than that of cesarian section delivery(3.31+/-0.33 microIU/mL)(P<0.05). TSH level was 5.18+/-0.93 microIU/mL in asphyxiated newborns and 2.97+/-0.84 microIU/mL in non-asphyxiated newborns(P< 0.05). TSH level in infants with maternal DM(8.911+/-1.25 microIU/mL) was higher than that of infants without maternal DM(4.32+/-0.42 microIU/mL)(P<0.05). TSH level was 5.28+/-0.42 microIU/mL in infants with maternal preeclampsia and 3.65+/-0.46 microIU/mL in infants without maternal preeclampsia(P<0.05). Thyroid hormones were lower in infants with perinatal asphyxia(P<0.05). In asphyxiated infants, T3 level was 75.33+/-55.65 ng/mL and free T4 was 0.54+/-0.21 ng/mL. T3 and free T4 level was 109.85+/-41.77 ng/mL and 0.76+/-0.22 ng/mL each in infants without perinatal asphyxia. Among the perinatal factors, gestational age, 1 min Apgar score and maternal DM influenced TSH level independently. CONCLUSION: In our study, cord blood TSH and thyroid hormone levels were affected by perinatal stress events.

ABSTRACT

OBJECTIVE: Fetal adrenal gland hormone was known to have close association with fetal weight and labor pain in response to fetal stress. Our purpose was to analyze the correlation between cortisol, DHEA-S in cord blood and obstetric status of fetuses. METHODS: We collected cord blood samples from 60 neonates immediately after delivery of baby. Six cases were complicated by intrauterine growth restriction and fourteen patients were complicated by preeclampsia. We measured cortisol, DHEA-S levels by using the RIA commercial Kits for the ELISA. We performed statistic analysis of the data on the SPSS computer program. RESULTS: Cortisol was significantly higher in intrauterine growth restriction (23.4 +/- 16.2 microgram/dL) statistically than control group (13.7 +/- 9.5 microgram/dL) (P=0.022). Cortisol and DHEA-S had negative correlation each other (P=0.025). DHEA-S was significantly lower in intrauterine growth restriction (1202.2 +/- 1005.9 ng/ mL) than control group (1714.8 +/- 978.6 ng/mL) (P=0.01). DHEA-S had increased with advancing gestational age (P=0.03) and fetal weight (P=0). CONCLUSION: Cord blood cortisol level and DHEA-S level has close association with intrauterine growth restriction and negative correlation with each other.

ABSTRACT

OBJECTIVE: The aim of this article was investigated whether changes of superoxide dismutase isozymes in the placenta of patients with preeclampsia contribute to radical-induced tissue injury. METHODS: The activities of antioxidant enzymes (superoxide dismutase (SOD), catalase, glutathione peroxidase (GSHPx)) and the contents of thiobarbituric acid reactive substance (TBARS) in the erythrocytes and in the placenta were assayed from 35 women with preclampsia and 35 normotensive pregnant women. RESULTS: The superoxide dismutase (SOD) activities were significantly reduced in the erhtyrocytes and the placenta of patients with pre-eclampsia compared with normotensive pregnant women. The activity of catalase was increased in the erythrocytes of patients with preeclampsia but the statistically significant difference of catalase activity in the placenta and GSHPx activity in both erythrocytes and placenta were not observed. The contents of TBARS were increased significantly in the erythrocytes and placenta of patients with preeclampsia. In preeclamptic placenta, copper and zinc containing superoxide dismutase (CuZn-SOD) was decreased (3.9+/-0.5 vs 5.1+/-0.6 U/mg protein) whereas manganeus containing superoxide dismutase (Mn-SOD) was increased (2.0+/-0.3 vs 2.7+/-0.4 U/mg protein). CONCLUSION: In these results, the decreased CuZn-SOD activity may some roles in increment of TBARS contents in pre-eclamptic placenta and decreased CuZn-SOD activity may be more prone to oxidative stress in the placenta.

ABSTRACT

PURPOSE: Endocrine abnormalities are common feature of chronic renal failure. The purpose of this study is to understand women's hormonal changes in connection with renal transplantation and to verify improved quality of life of recipient by comparing level of sexual hormone between renal transplant recipients and dialyzed patients. METHODS: To evaluate the level of hormones before and after female renal transplantation, we measured FSH, LH, estradiol, progesterone and prolactin (PRL) in 10 renal transplant recipients (RTR), 10 chronic renal failure patients (CRF) undergoing dialysis (hemodialysis or peritoneal dialysis) and 10 healthy, regularly menstruating women (controls). RESULTS: All 30 females' mean age was 37.83 years. All 10 RTR were menstruating and mean age was 38.6 years and mean serum creatinine (sCr) level was 1.09 mg/dL. Of ten dialyzed patients (6 hemodialysis and 4 peritoneal dialysis), nine of ten dialyzed patients had menstrual disturbance and their mean age was 37.5 years and mean sCr level was 9.8 mg/dL. In RTR, serum PRL and LH level were reduced compared with CRF patients, but these hormones were increased compared with controls. In RTR, progesterone level was significantly lower compared with controls, whereas slightly decreased compared with CRF patients. Estradiol level in dialyzed patients was significantly higher compared with RTR or controls and in RTR was increased compared with controls. CONCLUSION: Following successful renal transplantation, uremic hormonal abnormalities were ameliorated. However, these hormonal changes are not always fully restored which can be attributed to renal insufficiency grade or result from the administered immunosuppressive treatment.

ABSTRACT

PURPOSE: Long-term stress to the fetus causes alterations in adrenal steroidogenesis. The purpose of this study was to analyze the association of cord blood cortisol with stress during delivery. METHODS: Cord blood samples were collected from 58 neonates at once to labor. Cortisol was measured by RIA method(DPC, USA). Cortisol level according to gestational age(38 wks) and method of delivery(Cesarean section vs. vaginal delivery), Apgar score and uterine contraction, were compared to know stress during labor. RESULTS: Cortisol of cord blood had considerable differences between each group, according to gestational age(P<0.001). It was statistically higher in the cases of vaginal delivery than cessarian delivery(P<0.001). The concentration of cortisol was significantly higher according to duration of labor (P<0.05). There was a significant relationship between cortisol level and uterine contraction(P<0.05). The concentration of cortisol was significantly low when Apgar score at 1 min was low(P<0.05). CONCLUSION: Cord cortisol has close association with stress during labor. And so do with post birth prognosis of neonate.

ABSTRACT

BACKGROUND: The extrauterine fetal incubation system must meet stable blood gas exchange and sufficient oxygen supply to provide the physiologic oxygen consumption of the fetus. In the fetus, blood gas exchange is totally sustained by the placental circulation. The placenta can be regarded as an extracorporeal organ, and the basic structure of placental circulation comprises arteriovenous (AV) bypass. To mimic this mode of circulation, we used AV ECMO (extracorporeal membrane oxygenation) in the goat fetus, and attempted to achieve stable blood gas exchange and oxygen supply to the fetus. METHODS: Pregnant goats, weighting 30 - 35 kg, were anesthetized with N2O-O2-enflurane. We performed a cesarean section with a midline incision, and cannulated via the umbilical vessels after a hysterotomy, and connected the fetuses to an ECMO circuit. The fetus was transferred to an incubator containing normal saline mixed with antibiotics. Blood samples were obtained every 4 to 6 hours from the circuit for electrolytes, hemoglobin and blood gas analysis and arterial blood pressure and heart rate were monitored through the umbilical artery. Oxygen delivery and consumption were calculated from the measured parameters. Microscopic examinations of the liver, kidney and lung were performed 24 hours after ECMO to know the effect of AV ECMO on the circulation of the organ. RESULTS: AV ECMO was done for 24 hours in the six goat fetuses and the main cause of death was circulatory failure. Heart rates and blood pressure were stable during ECMO. Sodium bicarbonate was injected when mild acidosis occurred and blood gas exchange was maintained stable. Mean pump flow rate was 156 +/- 62 ml/min/kg and oxygen extraction ratio was 30.4%. The liver function tests were sustained within normal limits both before and 24 hours after ECMO, but BUN and creatininincreased beyond upper normal limits 24 hours after ECMO. Microscopic features of the liver and kidney showed congestion 24 hours after ECMO. The fetal lung after 24 hours of ECMO especially showed an increase of mature capillaries in the septum and wall of alveoli compared with the twin fetal lung. CONCLUSIONS: These results indicate that the extrauterine fetal incubation model used for this study was suitable to blood gas exchange and utility of oxygen for goat fetuses.

ABSTRACT

The fetus is an unstable subject for an isolated physiological and biochemical study. To study the fetus in a controlled and stable environment, a trial was done using 12 goat fetuses. Extrauterine incubation system was devised using an extracorporeal membrane oxygenation system. The system consisted of a venous reservoir with a servo-controlled roller pump and a membrane oxygenator. The extra-corporeal circuit and membrane oxygenator were primed with the maternal whole blood of 200 mL. Fetal umbilical cords was exposed by Cesarean section. Fetal umbilical arterial blood was drained via the drainage cannula. The drained blood was perfused to the oxygenator by the roller pump. The highly oxygenated and decarboxylated blood was returned to an umbilical vein via the perfusion catheter. The blood flow rate was controlled manually using a roller pump. Fetal heart rate, blood pressure, and electrocardiogram were continuously recorded. Gas analysis of drained and perfused bood was performed hourly. With this system, the fetuses were able to survive under fairly stable physiological condition for periods of up to 34 hr. The extrauterine incubation system used in this study could therefore be a encouraging future experimental model in researching the artificial placenta for premature fetuses.

ABSTRACT

OBJECTIVES: The purpose of this study is to establish animal model of extracorporeal membrane oxygenation (ECMO) system that uses membreane type oxygenator and circulation circuit of umbilical artery and vein. Blood gas and hemodynamic changes in the fetal goat undergoing ECMO were also evaluated. METHODS: Total 15 pregnant goat had been used to perform extrauterine fetal incubation using ECMO through umbilical artery and vein. Cesarean-section was performed to pregnant goat (35 kg) of 120-130 days of gestation to insert catheters (8 Fr) into the umbilical artery and vein. The tip of inserted catheter's the other end was connected with the circuit system including membrane type oxygenator (Polystan) and roller pump. A total of 300 ml of blood was drawn from donor nonpregnant goat and primed into circuit on the day of surgery. The goat fetus was immersed in a chamber filled with artificial amniotic fluid to monitor blood flow dynamics and blood gas was analyzed. RESULTS: The ECMO system using umbilical cord in the extrauterine incubation of fetal goat was developed and maximum survival of goat fetus was 34.5 hrs (mean survival was 856.6+/-688 min). Oxygen tension (PO2) in umbilical artery and vein were 20.53+/-2.54 mmHg, 31.03+/-13.03 mmHg and oxygen saturation (SO2) in umbilical artery and vein were 46.61+/-18.14 mmHg, 71.56+/-15.39 mmHg. Mean blood flow was 176+/-62 ml/min/kg. CONCLUSION: We suggest that our experimental model as an extrauterine fetal research could be a reasonable method in future advanced studies. However, longterm survival of extrauterine fetus needs more suitable hemodynamic and blood gas condition supported by further researches.
