Immunogenicity and Safety of Vaccines against Coronavirus Disease in Actively Treated Patients with Solid Tumors: A Prospective Cohort Study / Journal of the Korean Cancer Association, 대한암학회지

Purpose@#We aimed to assess the humoral response to and reactogenicity of coronavirus disease 2019 (COVID-19) vaccination according to the vaccine type and to analyze factors associated with immunogenicity in actively treated solid cancer patients (CPs). @*Materials and Methods@#Prospective cohorts of CPs, undergoing anticancer treatment, and healthcare workers (HCWs) were established. The participants had no history of previous COVID-19 and received either mRNA-based or adenovirus vector–based (AdV) vaccines as the primary series. Blood samples were collected before the first vaccination and after 2 weeks for each dose vaccination. Spike-specific binding antibodies (bAbs) in all participants and neutralizing antibodies (nAbs) against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) wild-type, Delta, and Omicron variants in CPs were analyzed and presented as the geometric mean titer. @*Results@#Age-matched 20 HCWs and 118 CPs were included in the analysis. The bAb seroconversion rate and antibody concentrations after the first vaccination were significantly lower in CPs than in HCWs. After the third vaccination, antibody levels in CPs with a primary series of AdV were comparable to those in HCWs, but nAb titers against the Omicron variant did not quantitatively increase in CPs with AdV vaccine as the primary series. The incidence and severity of adverse reactions post-vaccination were similar between CPs and HCWs. @*Conclusion@#CPs displayed delayed humoral immune response after SARS-CoV-2 vaccination. The booster dose elicited comparable bAb concentrations between CPs and HCWs, regardless of the primary vaccine type. Neutralization against the Omicron variant was not robustly elicited following the booster dose in some CPs, implying the need for additional interventions to protect them from COVID-19.

Clinical Implication of Candida Score in Multidrug-Resistant Pneumonia with Airway Candida Colonization

Background@#The growth of Candida in respiratory secretions is usually considered colonization, and antifungal therapy is rarely required. The role of Candida colonization in the progression of bacterial pneumonia remains controversial. The aim of this study was to identify the clinical implication of Candida score by analyzinge the relationship with multidrug-resistant (MDR) pneumonia and prognosis in patients with airway Candida colonization. @*Materials and Methods@#This study was a retrospective review of patients with airway Candida colonization by bronchial washing or bronchoalveolar lavage. The Candidascore was calculated according to the four factors (severe sepsis, surgery at baseline, total parenteral nutrition, and multifocal Candida colonization). Pneumonia related mortality or hopeless discharge expecting death was defined as a poor outcome. @*Results@#A total of 148 patients were enrolled in the study. In a multivariate analysis model, Candida score was identified as an independent predictor of poor outcomes (odds ratio 2.23;95% confidential interval 1.57 – 3.17; P<0.001) in pneumonia patients with airway Candida colonization. With a Candida score of three or higher compared with low score group, it was associated with bacterial pneumonia, especially methicillin-resistant Staphylococcus aureus (MRSA) infection (0.0% vs. 15.2%, P = 0.004). In addition, patients with a high Candida score had a longer hospital stay (13 vs. 38 days, P <0.001), longer duration of intensive care (7 vs.18 days, P <0.001), and higher pneumonia-related mortality (0.0% vs. 45.5%,P <0.001) as compared to the low Candida score group. The Candida score showed a positive correlation with other pneumonia severity scales such as CURB-65 (Confusion, Urea, Respiratory rate, Blood pressure, and age ≥65 years) (r = 0.461, P <0.001), Pneumonia Severity Index (r = 0.397, P <0.001), and predisposition, insult, response, and organ dysfunction (PIRO) score (r = 0.425, P <0.001). @*Conclusion@#This study revealed that Candida is no longer a bystander of airway colonization, and that it affects the progression of bacterial pneumonia, including multidrug-resistant pathogens, particularly MRSA infection. Also Candida score can be used to predict the prognosis of patients with pneumonia.

Epidemiological Study of an Outbreak of KPC-2-producing Klebsiella pneumoniae in a Tertiary Hospital in Korea / 대한임상미생물학회지

Background@#The prevalence of carbapenemase-producing Enterobacteriaceae (CPE), especially the KPC-2-producing Klebisella pneumoniae, is rapidly increasing and becoming a menace to global public health. This study aims to present the molecular epidemiology of the KPC-2-producing K. pneumoniae isolates emerged in a tertiary hospital in South Korea and describe its clinical significance. @*Methods@#This study included carbapenem-resistant K. pneumoniae isolates collected from a tertiary hospital from April to December in 2018. Antimicrobial susceptibility of K. pneumoniae isolates was tested using disk diffusion method. PCR and DNA sequence analyses were performed to identify the resistance genotype. In addition, the molecular epidemiology was investigated using pulsed-field gel electrophoresis (PFGE) and multilocus sequencing typing (MLST). @*Results@#Total 100 KPC-2-producing K. pneumoniae isolates were collected, which were mainly classified into two pulsotypes according to the XbaI restriction digestion pattern by PFGE analysis (pulsotype A, n = 31; pulsotype B, n = 63). The isolates exhibiting pulsotype A belonged to ST395 and the remaining isolates exhibiting pulsotype B were attributed to ST307 by MLST analysis. @*Conclusion@#This study investigated clinical information and molecular bacterial profiles for KPC-2-producing K. pneumoniae isolates. These findings indicate that the proper infection control activities are needed to prevent the spread of multidrug-resistant organisms such as CPE, which could cause high mortality in clinical field.

Impact of Cytomegalovirus Disease on New-Onset Type 2 Diabetes Mellitus: Population-Based Matched Case-Control Cohort Study

BACKGROUND: A latent cytomegalovirus (CMV) cause chronic inflammation through undesirable inflation of cell-mediated immune response. CMV immunoglobulin G has been associated with cardiovascular disease and type 1 diabetes mellitus. We evaluated impact of CMV diseases on new-onset type 2 diabetes mellitus (T2DM).METHODS: From the Korean Health Insurance Review and Assessment Service claim database of entire population with 50 million, we retrieved 576 adult case group with CMV diseases diagnosed with International Statistical Classification of Diseases and Related-Health Problems 10th Revision (ICD-10) B25 code between 2010 and 2014 after exclusion of patients with T2DM to 2006. The 2,880 control patients without T2DM from 2006 to cohort entry point were selected between 2010 and 2014 by age, sex matching with case group. The subjects without new-onset T2DM were followed until 2015. T2DM, hypertension (HTN), dyslipidemia (DYS), and end-stage renal disease (ESRD) were coded as ICD-10.RESULTS: The frequency of new-onset T2DM in case group was significantly higher than that in control (5.6% vs. 2.2%, P<0.001). The group with T2DM (n=95) had higher incidence of CMV diseases than the group without T2DM (n=3,361) (33.7% vs. 16.2%, P<0.001). In multivariate regression model adjusted by age, sex, lower income, HTN, and DYS, the incidence rate (IR) of T2DM in case group was significantly higher than that in the control group (IR per 1,000, 19.0 vs. 7.3; odds ratio, 2.1; 95% confidence interval, 1.3 to 3.2). The co-existence of HTN, DYS, and ESRD with CMV diseases did not influence the IR of T2DM.CONCLUSION: CMV diseases increase the patients' risk of developing T2DM.

Can Aminoglycosides Be Used as a New Treatment for Helicobacter pylori? In vitro Activity of Recently Isolated Helicobacter pylori

BACKGROUND@#Smectite can serve as a drug delivery system and gentamicin-intercalated smectite hybrids are expected to supersede the standard therapy for Helicobacter pylori eradication. The aim of this study was to confirm whether the minimum inhibitory concentration (MIC) of aminoglycosides applied as smectite hybrids remained low against recently isolated H. pylori strains.@*MATERIALS AND METHODS@#A total of 140 strains were collected for a minimum period of 3 years. Antimicrobial susceptibility tests were performed, and the MICs of eight antibiotics (amoxicillin, clarithromycin, metronidazole, tetracycline, levofloxacin, gentamicin, netilmicin, and tobramycin) were determined by using the Epsilometer test and following the European Committee on Antimicrobial Susceptibility Testing recommendations.@*RESULTS@#The resistance rate of clarithromycin was high, up to 30.7%, although it is a major antimicrobial agent used in standard therapy. The MIC50 and MIC90 of gentamicin (0.25 mg/L and 0.75 mg/L) and netilmicin (0.19 mg/L and 0.75 mg/L) were lower than other alternative therapies for H. pylori eradication. In clarithromycin-resistant strains, the MIC50 was 0.25 mg/L and the MIC90 was 1 mg/L for gentamicin; for netilmicin, the values were 0.25 mg/L and 0.75 mg/L, respectively.@*CONCLUSION@#Through the use of gentamicin and netilmicin, which have low MICs for H. pylori, aminoglycoside-intercalated smectite hybrids are expected to emerge as a new standard therapy for H. pylori eradication.

Peptide Nucleic Acid Probe-Based Analysis as a New Detection Method for Clarithromycin Resistance in Helicobacter pylori

BACKGROUND/AIMS: Helicobacter pylori eradication rates are decreasing because of increases in clarithromycin resistance. Thus, finding an easy and accurate method of detecting clarithromycin resistance is important. METHODS: We evaluated 70 H. pylori isolates from Korean patients. Dual-labeled peptide nucleic acid (PNA) probes were designed to detect resistance associated with point mutations in 23S ribosomal ribonucleic acid gene domain V (A2142G, A2143G, and T2182C). Data were analyzed by probe-based fluorescence melting curve analysis based on probe-target dissociation temperatures and compared with Sanger sequencing. RESULTS: Among 70 H. pylori isolates, 0, 16, and 58 isolates contained A2142G, A2143G, and T2182C mutations, respectively. PNA probe-based analysis exhibited 100.0% positive predictive values for A2142G and A2143G and a 98.3% positive predictive value for T2182C. PNA probe-based analysis results correlated with 98.6% of Sanger sequencing results (κ-value=0.990; standard error, 0.010). CONCLUSIONS: H. pylori clarithromycin resistance can be easily and accurately assessed by dual-labeled PNA probe-based melting curve analysis if probes are used based on the appropriate resistance-related mutations. This method is fast, simple, accurate, and adaptable for clinical samples. It may help clinicians choose a precise eradication regimen.

An atypical case of Lemierre syndrome following oropharyngeal infection / 고신대학교의과대학학술지

Lemierre syndrome is characterized by anaerobic bacterial infection in the head and neck and clinical or radiological evidence of internal jugular vein thrombophlebitis. The most common pathogens are Fusobacterium species, particularly Fusobacterium necrophorum. Septic emboli resulting from infected thrombophlebitis of the internal jugular vein leads to metastatic infections involving lung, liver, kidney, bone and central nervous system. The accurate diagnosis and treatment is important because it may be associated with a high mortality rate if untreated. We present a case of 28-year-old man with an atypical history for the diagnosis of Lemierre syndrome, which showed no definite evidence of internal jugular thrombophlebitis.

Effect of Central Line Bundle Compliance on Central Line-Associated Bloodstream Infections

PURPOSE: The present study aimed to evaluate the effect of central line (CL) bundle compliance on central line-associated bloodstream infections (CLABSIs) in different departments of the same hospital, including the intensive care unit (ICU) and other departments. MATERIALS AND METHODS: The four components of the CL bundle were hand hygiene, use of maximal sterile barrier precautions, chlorhexidine use, and selection of an appropriate site for venous access. Compliance of the CL bundle and CLABSIs were measured for every department [emergency room (ER), ICU, general ward (GW), and operating room (OR)]. A total of 1672 patients were included over 3 years (August 2013 through July 2016). RESULTS: A total of 29 CLABSI episodes (1.73%) were identified, and only 53.7% of the patients completed CL bundles. The performance rates of all components of the CL bundle were 22.3%, 28.5%, 36.5%, and 84.6% for the ER, ICU, GW, and OR, respectively. The highest CLABSI rate was observed in patients of the ICU, for whom all components were not performed perfectly. Conversely, the lowest CLABSI rate was observed for patients of GWs, for whom all components were performed. Among individual components, femoral insertion site [relative risk (RR), 2.26; 95% confidence interval (CI), 1.09–4.68], not using a full body drape (RR, 3.55; 95% CI, 1.44–8.71), and not performing all CL bundle components (RR, 2.79; 95% CI, 1.19–6.54) were significant variables associated with CLABSIs. CONCLUSION: This study provides direct evidence that completing all CL bundle components perfectly is essential for preventing CLABSIs. Customized education should be provided, according to specific weaknesses of bundle performance.

Change in Renal Function among HIV-Infected Koreans Receiving Tenofovir Disoproxil Fumarate-Backbone Antiretroviral Therapy: A 3-Year Follow-Up Study

PURPOSE: Tenofovir disoproxil fumarate (TDF) is commonly prescribed as a fixed-dose, co-formulated antiretroviral drug for HIV-1 infection. The major concern of long-term TDF use is renal dysfunction. However, little is known about the long-term patterns of changes in renal function in HIV-infected Koreans receiving TDF. MATERIALS AND METHODS: We prospectively followed 50 HIV-infected Koreans, performing laboratory tests every 3 months during the first year and every 6 months for the next 2 years. Urine N-acetyl-β-D-glucosaminidase (NAG) and plasma cystatin-C were measured using samples collected in the first year. Data on renal function were retrospectively collected on HIV-infected patients receiving first-line TDF (n=40) and in antiretroviral therapy (ART)-naïve patients (n=24) for 3 years. Renal function was evaluated as estimated glomerular filtration rate (eGFR) from serum creatinine [Modification of Diet in Renal Disease (MDRD)] and cystatin-C. RESULTS: The eGFR (cystatin-C) showed significant changes from 0 to 48 wks (p=0.002), with the lowest levels at 24 wks (84.3±18.8 mL/min vs. 90.3±22.5 mL/min, p=0.021 by post hoc test). Urine NAG levels did not differ at 0, 12, 24, and 48 wks, although eGFR (MDRD) significantly decreased from 0 (98.7±18.9 mL/min/1.73 m²) to 144 wks (89.0±14.7 mL/min/1.73 m²) (p=0.010). The first-line TDF group had significantly lower eGFR (MDRD) than the ART-naïve group at 144 wks (89.7 mL/min/1.73 m² vs. 98.4 mL/min/1.73 m², p=0.036). Thirteen (26%) participants experienced a decrease in renal impairment of 10 mL/min/1.73 m² in eGFR (MDRD) at 144 wks. CONCLUSION: These data suggest that clinically meaningful renal injury can develop in HIV-infected Koreans receiving long-term TDF.

Long Pentraxin 3 as a Predictive Marker of Mortality in Severe Septic Patients Who Received Successful Early Goal-Directed Therapy

PURPOSE: Pentraxin 3 (PTX3) has been suggested to be a prognostic marker of mortality in severe sepsis. Currently, there are limited data on biomarkers including PTX3 that can be used to predict mortality in severe sepsis patients who have undergone successful initial resuscitation through early goal-directed therapy (EGDT). MATERIALS AND METHODS: A prospective cohort study was conducted among 83 severe sepsis patients with fulfillment of all EGDT components and the achievement of final goal. Plasma PTX3 levels were measured by sandwich ELISA on hospital day (HD) 0, 3, and 7. The data for procalcitonin, C-reactive protein and delta neutrophil index were collected by electric medical record. The primary outcome was 28-day all-cause mortality. RESULTS: 28-day all-cause mortality was 19.3% and the median (interquartile range) APHCH II score of total patients was 16 (13–19). The non-survivors (n=16) had significantly higher PTX3 level at HD 0 [201.4 (56.9–268.6) ng/mL vs. 36.5 (13.7–145.3) ng/mL, p=0.008]. PTX3 had largest AUC(ROC) value for the prediction of mortality among PTX3, procalcitonin, delta neutrophil index, CRP and APACHE II/SOFA sore at HD 0 [0.819, 95% confidence interval (CI) 0.677–0.961, p=0.008]. The most valid cut-off level of PTX3 at HD 0 was 140.28 ng/mL (sensitivity 66.7%, specificity 73.8%). The PTX3 and procalcitonin at HD 0 showed strong correlation (r=0.675, p<0.001). However, PTX3 at HD 0 was the only independent predictive marker in Cox's proportional hazards model (≥140 ng/mL; hazard rate 7.16, 95% CI 2.46–15.85, p=0.001). CONCLUSION: PTX3 at HD 0 could be a powerful predictive biomarker of 28-day all-cause mortality in severe septic patients who have undergone successful EGDT.

Chronic Myeloid Leukemia Following Radioactive Iodine Treatment for Thyroid Cancer: Two Case Reports and a Literature Review / 대한내과학회지

The incidence of thyroid cancer has increased rapidly worldwide, although most patients can survive for a long time without developing symptoms. While most thyroid cancers are treated with thyroidectomy alone, some patients are given additional radioactive iodine (RAI) in the form of 131I to treat thyroid cancer metastasis. RAI is associated with acute and chronic complications. Secondary malignancies are the most important in long-term cancer survivors. While many studies have reported the occurrence of acute myeloid leukemia after high-dose RAI, there are few reports on chronic myeloid leukemia (CML) after low-dose RAI treatment. Moreover, previous cases of CML following thyroid cancer were reported before the tyrosine kinase inhibitor (TKI) era. Here, we describe two cases of CML following thyroid cancer that were successfully treated with second-generation TKIs.

Acute Fulminant Myocarditis Recovered from Electro-Mechanical Dissociation in Scrub Typhus / 이화의대지

Scrub typhus, caused by Orientia tsutsugamushi, is an acute febrile illness. Characteristics of tsutsugamushi disease are fever, rash and eschar. However, severe complications might rarely occur, such as acute fulminant myocarditis caused by scrub typhus. Thus, there are few reports of recovery from seriously complicated cases. We report on an adult male with scrub typhus complicated with acute fulminant myocarditis with no previous comorbid illness who recovered successfully with proper treatment including antibiotics, ventilator support, percutaneous cardiopulmonary support, and continuous renal replacement therapy.

Oxaliplatin-Induced Immune-Mediated Thrombocytopenia: A Case Report / Journal of the Korean Cancer Association, 대한암학회지

Oxaliplatin is a third-generation platinum derivative used for metastatic or advanced colorectal cancer treatment. Although myelosuppression is the most common cause of oxaliplatin-induced thrombocytopenia, rare cases of oxaliplatin-induced immune-mediated thrombocytopenia are reported. We report a case of a 57-year-old woman with colon cancer who developed gum bleeding and petechiae after oxaliplatin infusion. Laboratory tests revealed grade 4 thrombocytopenia and grade 4 neutropenia. She recovered from the thrombocytopenia and accompanying neutropenia within 4 days with no recurrence following discontinuation of oxaliplatin. Physicians need to be aware of the risk of severe acute thrombocytopenia following oxaliplatin administration.

Chronic Tophaceous Gout in Multiple Spines: A Case Report and Literature Review

Gout typically affects the 1st metatarsophalangeal joint. Spinal gout is rarely reported. Moreover, involvement of extensive spines is remarkably unusual. We describe a case of a 76-year-old woman with gout involving cervical, thoracic, and lumbar spines and sacroiliac joint. She presented with fever, severe back pain, and polyarthralgia and had multiple tophi on both elbows and the left 2nd and 5th proximal interphalangeal (PIP) joints. Monosodium urate crystals were confirmed from tophi on the left 5th PIP joint by polarized optical microscopy. Magnetic resonance imaging and computed tomography showed joint space narrowing and bony erosions on cervical, thoracic, and lumbar spines, and sacroiliac joint. Fever, back pain, and polyarthralgia improved significantly with oral steroid therapy. Spinal gout can involve multiple spines and other joints and it can be improved by medical treatment only. It should be considered in patients with uncontrolled gout who have acute severe back pain.

Successful Treatment of Primary Biliary Cirrhosis with Adalimumab in a Patient with Overlap Syndrome

Primary biliary cirrhosis (PBC) is occasionally developed in patients with rheumatic diseases, such as systemic sclerosis or Sjogren's syndrome. However, there are a few reports of overlap syndrome with PBC. The authors report a case of a 36 year-old female with PBC and overlap syndrome. Systemic sclerosis was diagnosed in 2007, and rheumatoid arthritis in 2010. Adalimumab stopped because of her pregnancy plan in January 2012. One month after delivery, she felt increased hand joint pain and fatigue. Laboratory findings were as follows: elevated AST, ALT, ALP, r-GTP and positive anti-mitochondrial antibody. Histology of a liver biopsy revealed moderate porto-periportal and mild lobular inflammation with bile duct inflammation, which was consistent with PBC. She was treated with prednisolone and UDCA (urosodeoxycholic acid), but her disease was not controlled. From May 2013, she has been treated with adalimumab. Her arthritis was improved and liver function test normalized up until now.

Bile Acid Inhibition of N-type Calcium Channel Currents from Sympathetic Ganglion Neurons

Under some pathological conditions as bile flow obstruction or liver diseases with the enterohepatic circulation being disrupted, regurgitation of bile acids into the systemic circulation occurs and the plasma level of bile acids increases. Bile acids in circulation may affect the nervous system. We examined this possibility by studying the effects of bile acids on gating of neuronal (N)-type Ca2+ channel that is essential for neurotransmitter release at synapses of the peripheral and central nervous system. N-type Ca2+ channel currents were recorded from bullfrog sympathetic neuron under a cell-attached mode using 100 mM Ba2+ as a charge carrier. Cholic acid (CA, 10(-6) M) that is relatively hydrophilic thus less cytotoxic was included in the pipette solution. CA suppressed the open probability of N-type Ca2+ channel, which appeared to be due to an increase in null (no activity) sweeps. For example, the proportion of null sweep in the presence of CA was ~40% at +40 mV as compared with ~8% in the control recorded without CA. Other single channel properties including slope conductance, single channel current amplitude, open and shut times were not significantly affected by CA being present. The results suggest that CA could modulate N-type Ca2+ channel gating at a concentration as low as 10(-6) M. Bile acids have been shown to activate nonselective cation conductance and depolarize the cell membrane. Under pathological conditions with increased circulating bile acids, CA suppression of N-type Ca2+ channel function may be beneficial against overexcitation of the synapses.

CaMKII Inhibitor KN-62 Blunts Tumor Response to Hypoxia by Inhibiting HIF-1alpha in Hepatoma Cells

In rapidly growing tumors, hypoxia commonly develops due to the imbalance between O2 consumption and supply. Hypoxia Inducible Factor (HIF)-1alpha is a transcription factor responsible for tumor growth and angiogenesis in the hypoxic microenvironment; thus, its inhibition is regarded as a promising strategy for cancer therapy. Given that CamKII or PARP inhibitors are emerging anticancer agents, we investigated if they have the potential to be developed as new HIF-1alpha-targeting drugs. When treating various cancer cells with the inhibitors, we found that a CamKII inhibitor, KN-62, effectively suppressed HIF-1alpha specifically in hepatoma cells. To examine the effect of KN-62 on HIF-1alpha-driven gene expression, we analyzed the EPO-enhancer reporter activity and mRNA levels of HIF-1alpha downstream genes, such as EPO, LOX and CA9. Both the reporter activity and the mRNA expression were repressed by KN-62. We also found that KN-62 suppressed HIF-1alpha by impairing synthesis of HIF-1alpha protein. Based on these results, we propose that KN-62 is a candidate as a HIF-1alpha-targeting anticancer agent.

Acute Lymphoblastic Leukemia in a Jehovah's Witness Girl / 대한소아혈액종양학회지

Recent advances in the treatment of leukemia are closely related to the development of intensive chemotherapy, which needs multiple blood transfusions during bone marrow suppression. Patients of the Jehovah's Witness refuse blood transfusions and therefore hematologists are faced with major dilemma in the treatment of these patients with leukemia. We report an 11-year-old girl of Jehovah's Witness with acute lymphoblastic leukemia, who refused blood transfusions during chemotherapy. She was treated by intensive chemotherapy and her remission and induction was successful with the support of G-CSF and erythropoietin. She has been in remission state for over 6 years since the completion of chemotherapy. We also made a brief review of related literatures.

A Clinical Study of Aseptic Meningitis in Busan and Kyoungsangnamdo from April to July, 2002

PURPOSE: There was an outbreak of aseptic meningitis in Busan and Kyoungsangnamdo area from April to July, 2002. In this study, we reported the clinical manifestations, laboratory data and causative viruses. METHODS: 184 children with aseptic meningitis who had been admitted to Department of Pediatrics, Inje Paik Hospital in Kaegum and Dongrae between April and July 2002 were assessed. Virus isolation and serotype identification were performed by cell culture and reverse transcription-polymerase chain reaction(RT-PCR) of cerebrospinal fluid. RESULTS: The peak incidence was noted in May. Male-to-female ratio was 2:1. The age ranged from 2 years to 16 years. Mean age was 8.7+/-7.1 years. Clinical manifestations were fever(95.1%), headache(91.8%) and vomiting(89.7%). Mean duration of fever was 2.6 days. The numbers of peripheral blood leukocytes were 1,400-20,000/mm3 and mean value was 9,829/mm3. On cerebrospinal fluid examinations, leukocyte count was in range of 10-2,000(mean 301)/mm3, protein level in range of 10-196(mean 36.7)mg/dL and glucose level from 17 to 155(mean 58.3)mg/dL. Viruses were isolated 13(8.4%) out of 154 patients and serotypes were 6 cases of echovirus 6, 3 cases of echovirus 9, 1 case of echovirus 13, 2 cases of echovirus 25 and 1 case of echovirus 30. CONCLUSION: Aseptic meningitis was prevalent in Busan and Kyoungsangnamdo area from April to July, 2002. We thought that causative viruses were echovirus 6, 9, 13, 25, 30.

A Case of Pregnant Woman with 46 , X , del ( X ) ( q 26 ) Turner Karyotype Whose Fetus Shows the Same Karyotype / 대한산부인과학회잡지

Turner syndrome with abnormalities of X chromosome is generally characterized by gonadal dysgenesis causing premature ovarian failure, primary and secondary amenorrhea. Premature ovarian failure is often caused by X chromosome aberrations. It has been shown that gross X chromosome abnormalities such as monosomy X usually result in primary amenorrhea and poor pubertal development, whereas mild X chromosome abnormalities such as partial X deletions usually lead to secondary amenorrhea and fairly good pubertal development. Fertility has been reported in several patients with relatively small Xq deletions before the onset of premature ovarian failure, and the X chromosome abnormality is often inherited by offspring. We describe a 46,X,del(X)(q26) female with normal pregnancy, in whom same karyotype was found in the fetus by amniocentesis. We report this case with brief review of related literatures.
