To develop a clinical practice guideline for vaccination in patients with autoimmune inflammatory rheumatic disease (AIIRD), the Korean College of Rheumatology and theKorean Society of Infectious Diseases developed a clinical practice guideline according to the clinical practice guideline development manual. Since vaccination is unlikely to cause AIIRD or worsen disease activities, required vaccinations are recommended. Once patients are diagnosed with AIIRD, treatment strategies should be established and, at the same time, monitor their vaccination history. It is recommended to administer vaccines when the disease enters the stabilized stage. Administering live attenuated vaccines in patients with AIIRD who are taking immunosuppressants should be avoided. Vaccination should be considered in patients with AIIRD, prior to initiating immunosuppressants. It is recommended to administer influenza, Streptococcus pneumoniae, hepatitis A, hepatitis B, herpes zoster, measlesmumps- rubella virus, human papillomavirus, and tetanus-diphtheria-pertussis vaccines in patients with AIIRD; such patients who planned to travel are generally recommended to be vaccinated at the recommended vaccine level of healthy adults. Those who live in a household with patients with AIIRD and their caregivers should also be vaccinated at levels that are generally recommended for healthy adults.

Paragangliomas are rare extra-adrenal neoplasms of neural crest origin. The neoplasms may develop at various sites, but most are located in the para-aortic space along the sympathetic chain. A paraganglioma in the bile duct is very rare; only four cases of such tumors in the hepatic bile duct have been reported to date. Herein, we report on the first Korean case of a malignant paraganglioma in the common hepatic duct (with hepatic metastases) in a 75-year-old male. Computed tomography of the abdomen revealed a heterogeneously enhancing lesion in the common hepatic duct with dilatation of the intrahepatic ducts. After balloon sweeping, the mass exited spontaneously through the Ampulla of Vater. The mass was about 1.5 × 1.3 × 0.5 cm in its dimensions and the surface appeared to be necrotic and edematous. Microscopically, the tumor cells were arranged in a Zellballen pattern. The tumor was diagnosed as a malignant paraganglioma.

BACKGROUND/AIMS: Gallbladder polyps (GBP) are a common clinical finding and may possess malignant potential. We conducted this study to determine whether visceral obesity is a risk factor for GBP. METHODS: We retrospectively reviewed records of subjects who received both ultrasonography and computed tomography with measurements of the areas of visceral adipose tissue and total adipose tissue (TAT) on the same day as health checkups. RESULTS: Ninety-three of 1,615 subjects (5.8%) had GBP and were compared with 186 age- and sex-matched controls. VAT (odds ratio [OR], 2.941; 95% confidence interval [CI], 1.325 to 6.529; p=0.008 for the highest quartile vs the lowest quartile) and TAT (OR, 3.568; 95% CI, 1.625 to 7.833; p=0.002 for the highest quartile vs the lowest quartile) were independent risk factors together with hypertension (OR, 2.512; 95% CI, 1.381 to 4.569; p=0.003), diabetes mellitus (OR, 2.942; 95% CI, 1.061 to 8.158; p=0.038), hepatitis B virus positivity (OR, 3.548; 95% CI, 1.295 to 9.716; p=0.014), and a higher level of total cholesterol (OR, 2.232; 95% CI, 1.043 to 4.778; p=0.039 for <200 mg/dL vs > or =240 mg/dL). Body mass index and waist circumference were not meaningful variables. CONCLUSIONS: Visceral obesity measured by VAT and TAT was associated with GBP irrespective of body mass index or waist circumference.

BACKGROUND/AIMS: Angiotensin receptor blockers (ARBs) inhibit activated hepatic stellate cell contraction and are thought to reduce the dynamic portion of intrahepatic resistance. This study compared the effects of combined treatment using the ARB candesartan and propranolol versus propranolol monotherapy on portal pressure in patients with cirrhosis in a prospective, randomized controlled trial. METHODS: Between January 2008 and July 2009, 53 cirrhotic patients with clinically significant portal hypertension were randomized to receive either candesartan and propranolol combination therapy (26 patients) or propranolol monotherapy (27 patients). Before and 3 months after the administration of the planned medication, the hepatic venous pressure gradient (HVPG) was assessed in both groups. The dose of propranolol was subsequently increased from 20 mg bid until the target heart rate was reached, and the candesartan dose was fixed at 8 mg qd. The primary endpoint was the HVPG response rate; patients with an HVPG reduction of >20% of the baseline value or to <12 mmHg were defined as responders. RESULTS: The mean portal pressure declined significantly in both groups, from 16 mmHg (range, 12-28 mmHg) to 13.5 mmHg (range, 6-20 mmHg) in the combination group (P<0.05), and from 17 mmHg (range, 12-27 mmHg) to 14 mmHg (range, 7-25 mmHg) in the propranolol monotherapy group (P<0.05). However, the medication-induced pressure reduction did not differ significantly between the two groups [3.5 mmHg (range, -3-11 mmHg) vs. 3 mmHg (range, -8-10 mmHg), P=0.674]. The response rate (55.6% vs. 61.5%, P=0.435) and the reductions in mean blood pressure or heart rate also did not differ significantly between the combination and monotherapy groups. CONCLUSIONS: The addition of candesartan (an ARB) to propranolol confers no benefit relative to classical propranolol monotherapy for the treatment of portal hypertension, and is thus not recommended.

BACKGROUND: Cellular phone has become a necessary device for communicating in hospitals. Cellular phones contaminated with bacteria may serve as a fomite in the transmission of pathogens by the hands of medical personnel. We investigated the bacterial contamination of cellular phones used by medical personnel in a tertiary hospital. METHODS: Culture swabs were obtained from 101 cellular phones and 99 anterior nasal cavities from medical personnel using cellular phones. The swabs were inoculated on blood agar, MacConkey agar, mannitol salt agar, and enterococcal broths containing 6microgram/mL vancomycin for 48 h at 37degrees C. The bacteria were identified on the basis of colony morphology, gram staining characteristics, catalase test, coagulase test, and DNase test; Microscan (Siemens, USA) was used for the identification of enterococci. RESULTS: Of the 101 cellular phones, 13 were contaminated with Staphylococcus aureus (including 4 methicillin-resistant S. aureus [MRSA]), 61 with coagulase-negative staphylococci (CoNS) (including 38 methicillin-resistant CoNS), 27 with Micrococcus spp., 11 with diphtheroids, 67 with Bacillus spp., and 4 with viridans streptococci. No gram-negative bacilli were isolated. Nasal swabs yielded 36 S. aureus, including 9 MRSA. Only 1 of 9 cellular phones used by the MRSA carriers was contaminated with MRSA. CONCLUSION: Cellular phones used by some medical personnel were contaminated with pathogens such as S. aureus or MRSA. Although, the clinical implications of pathogens isolated from cellular phones have not been fully investigated, pathogens could be transmitted by the hands of medical personnel who are cellular phone users.

BACKGROUND: The quality control for genetic tests would be of great importance as the test volume and clinical demands increase dramatically. Diagnostic genetics subcommittee of KSQACL performed two trials for cytogenetics and molecular genetics surveys in 2009. METHODS: A total of 67 laboratories participated in the cytogenetic surveys, 30 laboratories participated in the FISH surveys, and 94 laboratories participated in the molsecular genetics surveys in 2009. RESULTS: Almost of them showed acceptable results. However, some laboratories showed unacceptable results for the karyotype nomenclature and detection of complex cytogenetic abnormalities in hematologic neoplasms, and most of them except one showed acceptable results in FISH surveys. The molecular genetics surveys included various tests: M. tuberculosis detection, hepatitis B (HBV) and C virus (HCV) detection and quantification, human papilloma virus (HPV) genotyping, Influenza A (H1N1) detection, gene rearrangement tests for leukemias and lymphomas, apolipoprotein E (APOE) genotyping, methylenetetrahydrofolate reductase (MTHFR) genotyping, hereditary breast and ovarian cancer genes (BRCA1 and BRCA2), and genetic tests for achondroplasia (FGFR3), FMS-like tyrosine kinase 3 (FLT3), JAK2, BRAF, hereditary disorders such as spinal muscular atrophy, Huntington disease (HD), spinocerebellar ataxia (SCA), Prader-Willi/Angelman syndrome (PWS/AS), mitochondrial encephalopathy with lactic acidosis and strokelike episodes (MELAS), myoclonic epilepsy ragged red fiber (MERRF), wilson disease (ATP7B) and cancer-associated genes (KRAS). Molecular genetic surveys showed excellent results in most of the participants. CONCLUSIONS: External quality assessment program for genetic analysis in 2009 was proved to be helpful in continuous education and evaluation of quality improvement.

BACKGROUND: Novel swine influenza (H1N1) was first identified in Mexico in April 2009. Because of its high infectivity and worldwide distribution, a rapid and efficient screening test is necessary. Here we evaluated the usefulness of a rapid antigen test currently in use, compared to real-time RT-PCR (rRT-PCR) as a screening test for detection of novel swine influenza (H1N1). METHODS: A total of 1,228 patients who visited Hallym University Kangdong Sacred Heart Hospital with influenza-like illness between 14 August 2009 and 30 September 2009, and were tested by both rapid antigen and rRT-PCR tests, were enrolled in this study. RESULTS: Sensitivity, specificity, predictive value of a positive test, and predictive value of a negative test for the rapid antigen test were 30.5%, 99.2%, 86.4% and 90.1%, respectively. Fifty-one (4.2%) patients were positive for both rapid antigen test and rRT-PCR, and 1,053 (85.7%) were negative for both rapid antigen test and rRT-PCR. A total of 124 (10.1%) patients showed a discrepancy between the two tests. Among them, 116 (9.4%) were only positive for rRT-PCR and 8 (0.7%) were only positive for the rapid antigen test. The latter 8 patients all showed negative H1/M2 results in rRT-PCR. There were significant differences in detection rates of the rapid antigen test between different H1 Ct (threshold cycle) interval groups and for different age groups (P<0.05). CONCLUSION: Although the rapid antigen test is easy to perform and provides fast results, its limits as a screening test for detection of novel swine influenza (H1N1) due to its low sensitivity compared to rRT-PCR need to be considered in practical situations.

Lowe syndrome (the oculo-cerebro-renal syndrome of Lowe, OCRL) is a multi-system disorder that affects the eyes, nervous system, and kidney. OCRL is a rare X-linked recessive disease with a prevalence of approximately 1 : 500,000. The clinical features of OCRL include congenital cataracts, growth and mental retardation, areflexia, hypotonia, and renal tubular dysfunction (Fanconi-type). Chronic metabolic acidosis and hypotonia may be the most important component affecting management of the peri-anesthetic period during general anesthesia. However, problems such as electrolyte imbalance, seizure, fragility of the bone structures, and increased intraocular pressure should also be considered during the perioperative period. We report here the perioperative management of a patient with Lowe syndrome during the removal of multiple scalp cysts under general anesthesia.

Antiphospholipid syndrome (APS) is a rare coagulation disorder associated with recurrent arterial and venous thrombotic events. The hemostatic aspects of antiphospholipid syndrome (APS) in patients requiring thrombectomy along with cardiopulmonary bypass present unique challenges to anesthesiologists.We present the case of a 36-year-old woman with thrombosis of the inferior vena cava as a result of APS with particular reference to the precautions that are necessary during the perioperative care.The particularly important things are the prevention of thrombotic or hemorrhagic complications, management of the associated thrombocytopenia and the laboratory methods of monitoring the perioperative anticoagulation in the setting of a prolonged clotting time.
