PURPOSE: The correlation between sonographic findings and clinical symptoms was investigated in the patients with mesenteric lymphadenitis who had recurrent acute abdomen. MATERIALS AND METHODS: Seventy-eight children with recurrent acute abdominal pain without obvious primary disease were evaluated by sonography. The initial and follow-up sonography were performed in 17 children. The abdomen was divided into 3 areas. The number and size of mesenteric lymph nodes were observed in each zone, and was compared with the clinical findings. RESULTS: In 56(71.8%) of 78 cases, good correlation was seen in the area of the greatest size and number of the lymph nodes in the sonography. Most severe symptom, was seen in the right lumbar area(49 cases) and umbilical area(7 cases). In 17 cases of follow up, 14 cases showed decrease size and number of mesenteric lymph nodes while 2 cases showed increase in size and number of the nodes with aggravated symptoms. CONCLUSIONS: Ultrasonography was useful to detect and localize the enlarged mesenteric lymph nodes. Initial and follow-up sonography showed good correlation between the changes in number and size of the lymph nodes and symptoms.

BACKGROUND: This study aimed to assess the status of infection control during influenza A pandemic (H1N1) 2009. METHODS: A questionnaire survey was conducted in November 2009 at the 100 hospitals designated by the Korea Centers for Disease Control and Prevention (KCDC) as influenza A pandemic (H1N1) 2009-treatment institutions. RESULTS: In 32.3% of the hospitals, the ventilation system of the influenza A pandemic (H1N1) 2009 isolation ward was separated from the hospital's ventilation system. With regard to wearing personal protective equipment while caring for patients with H1N1 infection, during usual patient contact, masks were always worn by all medical staff at all the hospitals; however, medical staff at 38.7% and 51.6% of the hospitals did not wear gloves and gowns, respectively. During aerosol-generating procedures, some medical staff wore surgical masks, whereas medical staff at 10% and 23.3% of the hospitals did not wear gowns and protective goggles, respectively. In all, 64.5% of the hospitals responded that the contents of the guidelines established by the KCDC were insufficient for reference purposes in actual practice. CONCLUSION: Some of influenza A pandemic (H1N1) 2009-treatment institutions are believed to be inadequate in facilities, infection control during patient treatment, and administrative measures among their efforts to prevent transmission in hospital. In preparation against the outbreak of similar diseases in the future, the government needs to establish guidelines highly applicable by medical staff, to secure exclusive spaces and personnel for treating infectious disease patients, and to develop personal protective gear support and management systems.

Adenosis tumor is a ra re tumor of the breast and primarily consists of adenosis. Authors report a case of surgically proved adenosis tumor in a 31-year-old woman. Mammogram showed a Iobulated, well-circumscribed mass with several surrounding radiolucent halos. In the center of the mass several linear radiolucent densities were seen with the appearance of a conglomerated well-circumscribed mass such as fibroadenoma. These linear radiolucent densities were consistent with the fat between the fibrous sclerosis in pathologic specimen. Ultrasonogram showed a well-circumscribed mass with homogeneous low echogenicity, partial posterior enhancement, and bilateral acoustic shadowings.

Respiratory syncytial virus is the most common cause of lower respiratory infection (bronchiolitis and pneumonia) of infancy and early childhood. We analyzed clinical and radiological features of 76 patients with lower respiratory infections by respiratory syncytial virus, which were diagnosed by indirect immunofluorescent test or culture of nasal aspirate in Hep-2 cell monolayer, during the period of January-December, 1991. There were peaks of incidences in March-May and November-December, accounting for 87% of eases. Sixty-two cases (82%) were under 1 year of age. Fifty cases(66%) had underlying diseases. Major radiographical findings were overaeration (83%), parahilar peribronchial infiltrates(67%), segmental or subsegmental atelectasis(32%), and segmental or lobar consolidation(16%). In 15 cases(20%), overaeration was the only radiological findings. There was no evidence of pleural effusion or hilar lymph node enlargement in all cases. By considerig clinical features(symptoms, age. Underlying diseases, epidemic seasons) in addition to the radiological findings, radiologists would be familiar with lower respiratory infection by respiratory syncytial virus. Air space consolidation, which is generally though to represent bacterial pneumonia, is also observed not infrequently in respiratory syncytial virus infections.

PURPOSE: Piccolo et al. advocated the usefulness of Tc-99m-MDP breast scan in differential diagnosis of breast mass with high accuracy. But there are little or no follow-up studies about it as we know. We studied Tc-99m-MDP uptake pattern and lesions/background ratio in patients complaining palpable breast lesions to evaluate the clinical usefulness of Tc-99m-MDP scan. MATERIALS AND METHODS: Total 34 patients were studied with physical examination, mammogram and Tc-99m-MDP scan prospectively. Anteroposterior and both lateral view of breast were obtained 5 minutes after iv injection of 740 MBq Tc-99m-MDP. Breast uptake pattern of Tc-99m-MDP was analyzed by a grade system: 0=no uptake, grade 1=bilateral diffuse uptake, grade 2=asymmetric faint uptake, grade 3=focal hot uptake. 20 cases were pathologically confirmed by excision biopsy or aspiration biopsy. 14 cases were normal in physical examination and mammo-grain. RESULTS: Pathologic results showed 7 carcinomas, 6 benign solid tumors, and 7 fibrocystic changes. Grade 3 pattern of Tc-99m-MDP uptake was noted in 4/7 carcinomas, 3/6 benign solid tumors, and 1/7 fibrocystic changes. Grade 2 pattern was 2/7, 0/7, 3/7 respectively. The average L/B ratio was 1.66 in carcinomas, 1.68 in benign solid masses, 1.20 in fibrocystic diseases, 1.05 in normal patients. L/B ratio was higher in carcinoma and benign mass groups than in fibrocystic change and normal control groups(p=0.005). But there was no statistical difference between L/B ratio of malignant mass group and benign mass group. CONCLUSION: Tc-99m-MDP scan is not suitable to routine clinical use for breast mass diagnosis. It might be used in limited conditions when whole body bone scan is planned.

McCune-Albright syndrome, which consists of cafe-au lait spots, multiple fibrous dysplasia, sexual precocity and endocrinal dysfunction such as pituitary, thyroid and adrenal aberrations, has been increasingly recognized recently. The etiology is now suggested that activating mutations on the gene that encodes the alpha subunit of stimulatory G protein cause McCune-Albright syndrome. The child presented with sexual precocity and elevated estrogen level was still persisted after left oophorectomy and right partial oophorectomy due to misdiagnosed as ovarian granulosa-theca cell tumor. Whole body bone scan revealed abnormal radiotracer uptake on left facial bone and left proximal femur. Facial bone MRI showed marked thickening of facial bone from fibrous dysplasia. And the patient had cafe-au-lait pigmentations on neck and buttock area. Other endocrine function was normal. Pathologic finding of ovary was finally confirmed with cystic follicles. Skull biopsy revealed fibrous dysplasia. And she was finally diagnosed McCune-Albright syndrome.

BACKGROUND: Coagulase negative staphylococcus (CNS) spp. is a major pathogenic organism of nosocomial and community-acquired urianry tract infections, and causes infrctions in the immunocompromised host, and in particular, bloodstream infetions in patent with indwelling devices. High prevalance of methicillin resistance has been noticed in CNS which also have been recongnized as an important multidrug resistant pathogen. The optimal phenotypic method for detecting methicillin resistance still remains controversial, and new guidelines for detecting methicillin resistance of CNS was proposed by NCCLS in January 1999. We evaluated the relationship between mecA gene by PCR method and antimicrobial susceptibility tests according to the new NCCLS guidelines. METHODS: A total of 82 CNS isolates were examined for MICs and penicillin MICs by disk diffusion and agar dilution method according to NCCLS guidelines, and detections, and detection of mecA gene by PCR. RESULT: In disk diffusion method, 66 strains (80.5%) and 63 strains (76.8%) showed resistance to penicillin and oxacillin, respectively, and in agar dilution method, 71 strains(86.6%) and 53 strains (64.6%), respectively. In PCR method, mecA genes were detected in 49 strains(59.8%). Comparing with mecA gene detection by PCR method, the sensitivity of disk diffusion and agar dilution method was 95.8% and 89.8%, repectively. However, the sensitivity of disk diffusion and agar dilution method was 65.3% and 75.5%, respectively using previous NCCLS criteria. CONCLUSION: The new criteria of NCCLS detects the methicillin resistance induced by mecA gene more sensitively than previous one.
