The authors analysed 261 cases of mycoplasmal pneumonia in children who were admitted to the pediatric department of Seoul Adventist Hospital between July 1986 and June 1991. The result obtained were as follows; 1) Yearly distribution of the cases showed high in 1987 and 1991, but no significant difference was noted in seasonally or monthly distribution. 2) The peak incidence of age was between 2 and 6 years of age, and the sex ratio of boy to girl was 1.1:1. 3) pulmonary manifestations were asthma in 21 cases (8.0%), atelectasis in 5 cases (1.9%), emphysema in 3 cases (1.2%), pleural effusion in 16 cases (6.1%), otitis media in 4 cases (1.2%) and sinusitis in 9 cases (3.4%). 4) Extrapulmonary complication were hepatitis in 53 cases (20.3%), skin rash in 9 cases (2.4%), proteinuria in 6 cases (2.3%), and hematuria in 4 cases (1.5%). 5) On the chest X-ray examination, the most common type of pneumonia was interstitial pneumonia (94 cases, 39.8%), and unilateral involvement was common (85.6%), and the most common involvement was right lower lobe (83 cases, 41.4%). 6) The relationship between the type of pneumonia and cold agglutinini titer, and between the type of pneumonia and Mycoplasma antibody titer were not found (P>0.05). 7) In the 16 cases of pleural effusion, The type of pneumonia was lobar, lobular (9 cases), bronchopneumonia (7 cases), and interstitial type was not present. The site of pneumonia was left (6 cases), right (9 cases), and 1 case showed bilatrality. The extent of pleural effusion was mild (10 cases), moderate (3 cases), and severe (3 cases). The result of pleural fluid exam in severe cases was all exudate. 8) The mean duration of admission was most common from 6 to 10 days. the mean duration of admission by the type of pneumonia was lobar, lobar (10.71+/-3.40), interstitial (8.78+/-2.14), and bronchopneumonia (8.83+/-2.47). 9) Both mycoplasma antibody test and cold agglutinin test were carried out in 185 cases and sensitivity of mycoplasma antibody test was 55.1%.

STUDY DESIGN: This is a retrospective study analyzing the results of chip PLIF with pedicle screw instrumentation for various spinal lesions. OBJECTIVES: To analyze the clinical and radiologic results of chip PLIF and to compare the amount of blood loss and transfusion and operation time with the ordinary PLIF. SUMMARY OF LITERATURE REVIEW: The ordinary PLIF has 86-95% of radiologic union rate and 80% of clinical satisfactory rate. The problems of ordinary PLIF were donor site morbidity, limited bone resources, prolonged operation time and excessive blood loss. MATERIALS AND METHODS: Forty patients were treated by chip PLIF utilizing cubical chip bone obtained from spinous process, facets and lamina from October 1995 to October 1997. Twenty-four patients, followed up over 12 months, were included in this study. Radiologic union, disc space collapse and change of kyphotic angle were assessed by simple X-ray and clinical results by improvement of back pain, radicular pain and change of neurological deficits. Twenty-nine patients treated by ordinary PLIF were compared concerning the operation time, amount of blood loss and transfusion. RESULTS: The mean age was 51.5 years(27-68 years) and mean follow-up was 20.7 months(12-30 months). Complete radiologic union rate was 47.6%, which was lower than ordinary PLlf. Satisfactory clinical result rate was 79%, which was similar with other fusion methods. Operation time, amount of blood loss and transfusion were less than the ordinary PLIF. There were three complications that were one dural tear ailed two pedicle screw breakages. CONCLUSION: There was no relationship between radiologic union rate and clinical satisfactory result after chip PLIF. Although operation time is relatively short and blood loss is less, it's not a good method to obtain nice bony union in spinal lesions.

The purpose of this study was to evaluate the human pulpal response to Dentin Bonding Desensitizer. Class v cavities were prepared on the buccal surfaces of the first premolars and Dentin Bonding Desensitizer(ALL-BOND Desensitizer, Bisco, Inc. U.S.A.) was applicated in ten experimental teeth, or ZOE(PROPAC, GC Co. TOKYO, JAPAN) cement in eight control teeth and cavities were filled with light curing glass ionomer(Fuji II LC, GC Co., TOKYO, JAPAN). At 3-day and 25-day postoperative interval, pulpal response was observed and evaluated histologically with light microscope. The results were as follows. : 1. At 3-day postoperative interval, the control teeth were grade 1 inflammatory cell response and grade 1 connective tissue response. 2. At 25-day postoperative interval, all control teeth were grade 1 inflammatory cell response and in three control teeth grade 1 connective tissue response were observed, and one teeth showed grade 2 connective tissue response. 3. At 3-day postoperative interval, the experimental teeth were grade 1 inflammatory cell response and grade 1 connective tissue response. Below the cavity a few inflammatory cell(PMNs) in odontoblastic layer, increased blood vessels and pulpal cells were seen and this pulpal response was similar to control teeth. 4. At 25-day postoperative interval, in four experimental teeth grade 1 inflammatory cell response and grade 1 connective tissue response were observed, and one experimental teeth showed mild inflammatory response. 5. At 3-day and 25-day postoperative interval, no reparative dentin deposition was seen. 6. Both experimental and control group, pulpal response showed difference between 3 and 25-day of postoperative interval. In control teeth, increased predentin and pulpal cells were seen and in experimental teeth, congestion of blood vessels and increased pulpal cells were seen. In conclusion, the pulpal irritation due to this Dentin Bonding Desensitizer was not severe, and it was considered that agent was not harmful to the human pulp.

We aimed to identify the clinical variables associated with a better glucose-lowering response to the sodium glucose cotransporter 2 inhibitor ipragliflozin in people with type 2 diabetes mellitus (T2DM). We especially focused on urinary glucose excretion (UGE). This was a single-arm multicenter prospective study. A total of 92 people with T2DM aged 20 to 70 years with glycosylated hemoglobin (HbA1c) levels ≥7.0% and ≤9.5% were enrolled. Ipragliflozin (50 mg) was added to the background therapy for these people for 12 weeks. After 3 months treatment with ipragliflozin, the mean HbA1c levels were decreased from 7.6% to 6.9% and 62.0% of the people reached the HbA1c target of less than 7.0% (P<0.001). In addition, body weight, blood pressure, and lipid parameters were improved after ipragliflozin treatment (all P<0.001). The baseline HbA1c (r=0.66, P<0.001) and morning spot urine glucose to creatinine ratio (r=−0.30, P=0.001) were independently associated with the HbA1c reduction. Ipragliflozin treatment for 12 weeks improves glycemic control and other metabolic parameters. A higher HbA1c and lower UGE at baseline predicts a better glucose-lowering efficacy of ipragliflozin.

Mycobacterium neoaurum is rapidly growing mycobacteria that can cause human infections. It commonly causes bloodstream infections in immunocompromised hosts, and unlike other mycobacteria species, it rarely causes pulmonary infections. We confirmed the first pulmonary infection case in Korea caused by M. neoaurum using full-length 16S rRNA gene sequencing.

Fifty nine patients who had been admitted to Seoul National University Hospital from April to October in 1986 were prospectively examined by a pulsed Doppler echocardiography on one day before cardiac catheterization. The sample volume was placed both just proximal and distal to pulmonic valve on 2-D echocardiogram. 1) Among the three morphologic patterns of the flow velocity, triangular and intermediate types indicate pulmonary hypertension (sensitivity 84%, specificity 86%), and round type indicates normal pulmonary arterial pressure (sensitivity 86%, specificity 84%). 2) In the group with pulmonary hypertension acceleration time and ejection time were measured shorter (P<0.01), and prejection period was measured longer than the group without pulmonary hypertension (P<0.05). 3) The best correlation was obtained between PEP/AT and mean pulmonary arterial pressure (r=0.77). Acceleration time alone also correlated well with mean arterial pulmonary pressure(r=-0.69). 4) In STI measurement and its correlation with pulmonary arterial pressure, no significant difference was observed when recorded in main pulmonary artery or right ventricular outflow tract. But in the latter position, late, systolic fluttering and variation in curve morphology occured less likely. 5) Our results indicate that the pulsed Doppler echocardiography is useful not only in the diagnosis of pulmonary hypertension but also in the quantitative estimation of pulmonary arterial pressure in different heart diseases. Futhermore this method may be a good tool for follow-up evaluation after surgical or medical treatment of patients with pulmonary hypertension.

Journal of the Korean Radiological Society 2007;57(3):235-238
PURPOSE: To determine computed tomography (CT) criteria for cardiomegaly. MATERIALS AND METHODS: We analyzed posteroanterior chest radiographs and CT scans of 200 patients (M:F=130:70, mean age 49 years old) that were performed on the same day. On plain radiographs, the cardiothoracic ratio (R) was calculated using a standard method. On CT, we measured the maximal cardiac width (D(c)) and the maximal thoracic width of a patient (D(t1)). A second thoracic width was measured at the same scan level of D(c). Thus, two cardiothoracic ratios were derived in one patient-D(c)/D(t1) (R(1)) and D(c)/D(t2) (R(2)). We analyzed the appropriateness of R(1) and R(2) in the diagnosis of cardiomegaly to establish criteria for the use of the cardiothoracic ratio (ROC curve). RESULTS: When cardiomegaly was defined as a value of R that was greater than 0.5, both R(1) and R(2) were useful indicators of cardiomegaly. For a cut-off value of 0.5 for the cardiothoracic ratio for cardiomegaly, the sensitivity of R(1) and R(2) was 84% and 68%, respectively, and the specificity of R(1) and R(2) was 72% and 86%, respectively. CONCLUSION: The cardiothoracic ratio on CT can be easily obtained by measurement of the maximal cardiac width divided by the maximal thoracic width at the same scan level. When the cardiothoracic ratio on CT is over 0.5, the presence of cardiomegaly can be suggested.

STUDY DESIGN: The authors retrospectively analysed the recovery of clinical symptoms after surgical treatment of lumbar HIVD. OBJECTIVES: To investigate the incidence of clinical symptoms, the recovery rate and time after surgical treatment and the difference between L4-5 and L5-S1 lesion. SUMMARY OF LITERATURE REVIEW: There are many reports concerning the clinical result of surgical treatment for the HIVD. They usually describe the result as excellent, good, fair and poor. We can't get any information about the recovery rate and recovery time of each clinical symptom from the reports . MATERIALS AND METHODS: Thirty-eight patients were treated by one level open discectomy from march 1991 to december 1995, The clinical symptoms and signs including SLR, motor deficit, sensory deficit, change of DTR and severity of radiating pain were periodically followed up on the predesigned protocol. RESULTS: In preoperative examination, SLR was positive in 82%, motor deficit in 76%, sensory deficit in 74%, DTR change in 50%, and radiating pain in 100%. The recovery rate of SLR was 96.8%, motor deficit ; 93.6%, sensory deficit ,78.6%, DTR change ; 21% and radiating pain ,84.2%. The average recovery time of SLR was 3.4 months, motor deficit ; 1.9 months, sensory deficit ; 5.3 months, DTR change ; 4.1 months and radiating pain ; 3.2 months. Motor and sensory deficit was more frequent in L4-5 lesion but DTR change was usually noted in L5-S1 lesion. The recovery rate and time showed no great difference between the two level. CONCLUSIONS: The recovery rate was higher in SLR, motor deficit and radiating pain rather than sensory deficit and DTR change. The recovery time was fastest in radiating pain but variable nature was noted in sensory deficit. Above results may be helpful to explain the prognosis of the lumbar HIVD.
