Adenoid is a kind of tonsil located in the posterior wall of nasopharynx. Enlargement of the adenoid can produce obstruction of the nasopharynx and Eustachian tube. Disturbance in discharge of nasal and paranasal secretions can be a cause of chronic rhinitis, sinusitis, and otitis media. Diagnosis of enlarged adenoid simply by inspection is difficult due to its location. Measurement of nasopharyngeal airway and adenoid using lateral radiographs of nasopharynx may be inaccurate for magnification and rotation. It was some limitations in demonstrating the actual state of nasopharyngeal airway and adenoid because it gives only two-dimensional informations. The authors measured the sizes and areas of nasopharyngeal airway and adenoid using MRI with sagittal and oblique coronal pilot views of T1 weighted spin echo. We categorized the patients into 4 groups according to the scoring system by symptoms such as apnea, mouth breathing, and snoring. The results of several measurements and their ratios were evaluated in these 4 categorized patients. The ratios of area of adenoid and nasopharyngeal airway(AA/Na) in each patient group were 6.52, 7.76, 10.53, 15.93, respectively. And the ratios of adenoid and nasopharyngeal airway (A/N) by Fujioka's method were 0.6, 0.65, 0.69, 0.71, respectively. We found that AA/Na might be the most effective index as an objective indicator in the evaluation of nasopharyngeal obstruction by the enlarged adenoid.

The authors reviewed findings of enhanced abdominal computed tomographic (CT) scans to the difference between a higher dose of conventional ionic contrast media(iothalamate meglumine) and a lower dose of a new, nonionic contrast material (ioversol). One hundred adult patients were divided into two groups. Each group consisted of 50 patients. Iothalamate meglumine and ioversol were intravenously administered in each group. The ratio of the male to female in the former was 28.22, and the latter 29:21. We examine the degree of renal streak artifact and measure the Hounsfield number of urine in renal collecting system. There were significant differences of the degree of the streak artifact depending upon the osmolality of contrast media used and that was related with urine CT number (P value<0.005). We authors conclude that nonionic low osmolar contrast media is prone to cause streak artifacts and distortions of renal image than conventional ionic high osmolar contrast media.

PURPOSE: It is suggested that persistent hypocarbia caused by ventilator therapy could be a risk factor in PVL. The study is aimed to discover whether for preventing hypocarbia with combined use of gentle ventilation and high frequency ventilation, other factors would be causers of PVL. METHODS: Among 45 infants who were born and survived through ventilator treatment in the Fatima neonatal intensive care unit for four years from April 1996 to June 1999, 15 infants with PVL were classified as a study group and 30 without PVL as control group. The analysis was performed retrospectively with medical records. Ventilator treatment was based on the combined use of ventilation by means of the flow interruptor type of Infant Star . The aggressive weaning was performed when the clinical state, chest X-ray and arterial blood gas analysis became stabilized. RESULTS: Among 15 cases with PVL : 9 cases(60.0%) with fetal distress, 1 case(6.6%) with placenta previa, 1 case(6.6%) with placenta abruptio. In the relationship between PaCO2 variance on arterial blood gas analysis and PVL, the highest average of PaCO2 is 44.9 +/- 7.8 mmHg in the study group and 45.0 +/- 10.5 mmHg in the control group, which means there was not statistically significant difference. The PaCO2 concentration lower than 25 mmHg for three days appeared in one case in the study group. CONCLUSIONS: In cases of preventing hypocarbia by combined use of ventilation, it is suggested that the birth history and weaning method is important as risk factor of PVL.

It has been known that estradial(E2) level is concerned with the quality, number and growing of follicles. Determination of the serum levels of E2 has been used to predict the oocyte maturity. We experienced the rare case who has significantly low serum E2 level(551.26 pg/ml) in spite of multiple ovarian responses by sonographic finding, but from her we obtained 23 oocytes on MCD#16 after COH with ultrashort protocol(HP-FSH 150 IU, daily). The numbers of retrieved oocyte were 23 and fertilization rate was 56.6%, so the result of IVF-ET was successful twin pregnancy. Serum estradiol level and sonographic finding are essential to measure the number and growing of follicles, but E2 levels may be too unreliable to be used as sole parameter for the number and maturity of oocytes.

The role of amino acids in culture media for IVF-ET was examined in a total of 76 cycles. Patients received clomiphene citrate (CC) followed by hMG or GnRH-a combined with gonadotropins (FSH/hMG) for controlled ovarian hyperstimulation. Severe male (<4 x10(6) motile sperm) or age factor (>39 y) patients were excluded in this study. Pregnancy was classified as clinical if a gestational sac or fetal cardiac activity was seen on ultrasound. No significant differences were found in age, duration of infertility, follicle size, the level of E2 on the day of hCG injection, the mean number of oocytes retrieved, total motile sperm count, fertilization rate and the mean number of embryos transferred between bHTF (without amino acids) and mHTF (with amino acids) groups. However, total ampules of gonadotropins were higher (p<0.01) in mHTF group than bHTF group. Significantly (p<0.05) more clinical pregnancies were recorded in mHTF group (13/30) compared with bHTF group (9/46). The multiple pregnancy rates were 11.1% in bHTF group and 77% in mHTF group. There were one ectopic pregnancy in mHTF group and one heterotopic pregnancy in bHTF group. Abortion rates were 22.2% in bHTF group and 7.7% in mHTF, respectively The ongoing pregnancy or livebirth .ate was significantly (p<0.05) higher in mHTF group (12/30) than bHTF group (7/46). These results suggest that the addition of amino acids in culture media is essential for culture of zygotes in vitro and adjustment of energy substrates in phosphate-free culture media appears to be beneficial for human IVF-ET procedure.

The aims of this study were to document bronchiolitis obliterans(BO), the long term pulmonary sequelae after mycoplasma pneumonia, and to evaluate the difference of development of BO according to antibody titer and X-ray pattern. Twenty five subjects who had mycoplasma pneumonia underwent high resolution CT(HRCT) 1.3 years(1.0-2.0 years) after the initial infection. Fifteen boys and 10 girls, with mean age of 6.3 years(3-15 year) at the time of the infection, were included. The clinical diagnosis of Mycoplasma pneumoniae(M. pneumoniae) pneumonia was confirmed by a fourfold or higher rise in the antibody titers between acute and convalescent phase or a single very high titers(> or = 1:640) and abnormal chest radiographs. The subjects were divided into two groups as high titer group(antibody titer 1:5120 1:20480, n=15) and low titer group(antibody titer 1:640-1:2560, n=10). Nine of 25 subjects(36.0%) demonstrated BO findings on HRCT which included mosaic perfusion in 8 of 9 subjects(88.9%), bronchiectasis in 6(66.7%), mosaic perfusion associated with bronchiectasis in 6(66.7%), bronchial wall thickening in two(22.2%), and decreased pulmonary vascularity in one(11.1%). Those findings were more commonly seen in high titer group compared to low titer group[53.3%(8/15) vs 10.0%(1/10), P<0.05] and lobar type compared to linear type[58.0%(7/12) vs 15.4% (2/13), P<0.05]. The involved areas on HRCT exactly corresponded with initially involved area on chest radiographs in 8 of 9 subjects (88.9%). The development of BO was closely related to the M. pneumoniae pneumonia and was noted significantly in individuals with high antibody titer and lobar type x-ray pattern. We suggest that it is necessary to pay attention to the development of BO after M. pneumoniae pneumonia with high antibody titer and lobar type x-ray pattern.

Journal of Korean Burn Society 2010;13(2):121-123
PURPOSE: The last decade has focused on healing as the major outcome of burn management with little attention paid to other important patient-centered outcomes, such as pain. Traditional standard dressings using silver sulfadiazine cream and vaseline gauze may result in significant pain at dressing change, wound dryness, increase necessity for dressing change, and also traumatizing the skin and wound bed. In this paper we introduce Mepitel(R), a new silicone dressing material showing satisfactory result than previous traditional standard dressings in burn dressing. METHODS: We conducted a prospective, observational study of 15 adult patients with second degree burn. At the arrive, we initially applied Mepitel(R) after bullae aspiration and changed the cover dressing depending on the degree of exudate from burn while still applying Mepitel(R) for 3 days. After dressing change, pain intensity was measured on an 11-point numeric rating scale. RESULTS: Mean time to wound reepithelization was 10.2 days and mean pain scores on a 11-point scale associated with dressing changes was 5.2 while requiring 0.5 intravenous narcotic administrations per dressing change. CONCLUSION: Mepitel(R) is a new grid like silicone coated nylon dressing containing no additional biologic compounds. The advantages of the Mepitel(R) are easy of use, non-adhesion to the wound, very good tolerance, keep moisture of wound and absence of pain during dressing change. This product has been used in our clinics and this paper serves as a report on our experiences with it.
