Respiratory distress syndrome (RDS) in the newborn infants remains a major cause of mortality and morbidity in the newborn period despite much improvements in neonatal intensive care and artificial ventilatory techniques. Gastric fluid was obtained from 151 patients within 6 hours after delivery. The sensitivity, specificity, and predictive value of the simple shake test (133 cases) and stable microbubble rating (SMR) test (151 cases) were assessed in the diagnosis of RDS, as well as the relation between both tests and RDS. We carried out both tests of on gastric aspirates all newborn who admitted to NICU of Presbyterian Medical Center from June 1991 to August 1992. The results were summarized as follows: 1) Among the total 151 cases, RDS were found in 41 cases(27.2%). 2) RDS occurence rate of the simple shake test was 11/11 in 0 group, 17/26 in +1 group, 8/28 in +2 group, 2/41 in +3 group, and 2/27 in +4 group. RDS occurence rate was high the 0 and +1 group. 3) RDS occurence rate of the SMR test was 4/4 in very weak group, 32/36 in weak group, 1/33 in medium group, and 4/78 in strong group. RDS occurence rate was high in the very weak and weak group. 4) Among the positive group of the SMR test 95 cases, positive group of the shake test were found in 87 cases. Among negative group of the SMR test 38 cases, negative of the shake test were found in 29 cases (correlation coefficient=0.763). 5) Sensitivity of the shake test and SMR test were 70%, 87.8% respectively. Specificity of the shake test and SMR test were 93.3%, 96.4% respectively. Positive predictability were 75.7%, 90% respectively and negative predictability were 87.5%, 95.5% respectively. The shake test, as Well as SMR test, has significant value to diagnosis of the RDS. We predict RDS occurence rate of the SMR test was significantly higher than shake test.

The VATER syndrome is a group of congenital anomalies with a nonrandom tendency for concurrence. Defects include vertebral, anorectal malformation, tracheoesophageal fisutla with esophageal atresia, radial-limb, vascular, and renal abnormalities. The critical period of organogenesis is at or before the sixth or seventh week of gestation. We experienced one case of VATER syndrome in a 1 day old male neonate having vertebral anomalies, esophageal atresia with tracheoesophageal fistula to the distal esophageal segment, imperforated anus, left renal dysplasia with hydronephrosis of the right kidney and both hydroureter, patent ductus arteriosus. We report a case of VATER syndrome with brief review of related literature.

While there is little controversy about the surgical resection for the torn discoid lateral meniscus, there are some contradictory reports for the treatment of discoid lateral meniscus without tear. Some authors argue that initial treatment should be observation after diagnostic arthroscopy in the cases without tear. Others reported that excellent results were obtained after partial resection of the discoid lateral meniscus without tear or with slight degeneration. We reviewed our series of symptomatic discoid lateral menisci without tear, confirmed by arthroscopic examination. We retrospectively reviewed 8 knees in 8 patients who had had partia! Meniscectomy for discoid latera1 meniscus without tear, confirmed by arthroscopic examination. They were 5 males and 3 females. The average age was 22.8 years (range, 7 to 57 years). The average duration of follow-up was 2 years and three months. The patients had continuing pain and locking or snapping preoperatively. Preoperative MRI had grade Il intrameniscal signal in all the cases. The patients were evaluated hy Lysholm pain score and total Lysholm score. There were 7 complete types and one incomplete type. The average Lysholm pain score and the total Lysholm score improved from 13.1, 67.8 preoperatively to 28.8. 97.9, at the last follow-up, respectively. Mechanical symptoms including click and 1ocking were disappeared in all, and no complication was obser ved. We suggest that symptomatic discoid lateral meniscus should he resected e.ven though there is no tear visible on arthroscopy, especially when the MRl shows grade lI intrameniscal signal.

PURPOSE: Authors investigated the associated findings and their value in the diagnosis of anterior cruciate ligament(ACL) injury in MR image. MATERIAL AND METHODS: The knee MR images of 47 patients with ACL injury(complete; 24, partial; 23) and 61 patients with normal ACL confirmed by the knee arthroscopy or operation were reviewed retrospectively. The degree of anterior translocation of tibia and the degree of posterior cruciate ligament(PCL) buckling were evaluated. The prevalence and pattern of associated adjacent bone, ligament and meniscus injuries were studied. RESULTS: The means( +/- 2standard errors) of anterior translocation were different significantly in statistical analysis(p<0.001, student t-test) between injury group(7.51 +/- 1.16mm) and normal group(-0.56 +/- 0.92mm). In the level of 5mm of anterior translocation for the criteria of ACL injury, the sensitivity, specificity, accuracy were 78.7%, 89.5%, 84.3% for each. The means of PCL buckling ratio were also different statistically b. etween injury group(0.23 +/- 0.02) and normal group(0.17 +/- 0.01)(p<0.001). In the level of 0.20 for diagnostic criteria of ACL injury, the sensitivity, specificity, accuracy were 71.4%, 83.6%, 78.4% for each. Thirty one medial meniscus tear(66%), thirteen lateral meniscus tear(28%), ten medial collateral ligament injury(28%), one PCL injury (2%) were associated with ACL injury. The twenty nine bone marrow changes were found in twenty patients {43%) which included acutely injured seven patients. In acute cases, the bone marrow changes were depicted as diffuse or focal high signal intensity lesions in lateral femoral or tibial condyles in contrast to the changes in chronic cases depicted as focal low signal intensity lesions in variable location. Lateral femoral condylar notch depression were found in nine patients(19%) and avulsion fractures of anterior tibial spine in four patients(9%). CONCLUSION: The associated findings with ACL injury (anterior translocation, buckling of PCL, associated bone, ligament and meniscus injuries) are considered to be helpful in the diagnosis of ACL injury on Knee MR images, when the findings of anterior cruciate ligament itself are not confirmative.

BACKGROUND: Anesthetic techniques for laryngeal microsurgery aims on modulation of sympathetic stimulation, good relaxation and rapid recovery from deep anesthesia. This study was designed to compare the influence of the different anesthetic methods on the cardiovascular responses and the recovery patterns during suspension laryngoscopic surgery. METHOD: Sixty patients of ASA class 1 or 2 scheduled for suspension laryngoscopic surgery were divided into 4 groups randomly. Two groups were anesthetized with inhalational anesthetic, enflurane, and other two groups were anesthetized with intravenous anesthetic, propofol. In each groups, esmolol or fentanyl was used as an adjunctive during anesthesia. When blood pressures increased above 30% of baseline value each adjunctive was added. The changes of blood pressure and heart rate were compared with each others during operation. Postoperatively, the start of spontaneous respiration, consciousness, memory, and the frequencies of other complications were also compared with each others. RESULT: The results were as follows; 1) The blood pressures and heart rates during operations were not different among the groups. 2) The recovery of spontaneous respiration was early in propofol esmolol group. 3) 30 minutes after operation, the consciousness state was better and complications were less in propofol groups compared with enflurane groups. CONCLUSION: From this results, it seems that propofol with nitrous oxide and supplemental fentanyl or esmolol may be useful in laryngeal microsurgery. Especially, esmolol can be a good substitute for those who can't be treated with opioids.

BACKGROUND AND OBJECTIVES: Platelets play an important role in the pathogenesis of acute coronary syndrome. Prostacyclin inhibits platelet aggregation, smooth muscle cell proliferation and vasoconstriction, and it counteracts thromboxane A2 activity. The purpose of this study is to evaluate the association between a single nucleotide polymorphism in the prostacyclin synthase gene and myocardial infarction in Koreans. SUBJECTS AND METHODS: We studied total 119 patients (M: F=72: 47, mean ages=57.9). We compared 60 acute coronary syndrome patients who underwent coronary angiography with the diagnosis of acute myocardial infarction (MI), with 59 normal control group patients who had normal coronary angiograms. With the use of polymerase chain reaction-restriction fragment length polymorphism analysis, we identified a single nucleotide polymorphism, C1117A, in exon 8. RESULTS: The genotype distribution and allele frequencies were significantly different between the control group and MI group. Frequency of the genotype C1117A was: AA: AC: CC=3.4%: 30.5%: 66.1% in control group, respectively, and AA: AC: CC=1.7%: 10.0%: 88.3% in MI group, respectively. Prostacyclin synthase polymorphism was observed in the MI group and the control group, but the frequency of the CC genotype was high in MI group (odds ratio, 3.88; 95% CI 1.49-10.88, p=0.003). Compared to control group, being male, having diabetes, hypertension or obesity, and the smoking rate were high in MI group. There were not significantly differences between genotypes for clinical characteristics. CONCLUSION: We conclude that the C1117A polymorphism in exon 8 of the prostacyclin synthase gene is associated with MI, and it may be a genetic marker of MI in Koreans.

PURPOSE: We evaluated the early outcomes of Gortex patch sling operation in the management of women with intrinsic sphincter deficiency(ISD). MATERIALS AND METHODS: 20 women underwent Gortex patch sling operation to treat genuine stress urinary incontinence and all patients had ISD. Patients were interviewed by telephone for incontinence, self-catheterization, and voiding symptoms at a mean of 16.6 months(range 6-35) after surgery. RESULTS: The mean age of the patients was 54.2 years and mean parity was 2. Mean operation time was 55 minutes(range 45-90) and mean duration of postoperative catheterization was 7.0 days(range 5-12). Success rate(complete dry) was 90% and de novo urge incontinence occurred in 3(15%). CONCLUSIONS: Gortex patch sling operation is a safe, simple and effective procedure for the treatment of stress incontinence due to ISD. However, further follow-up of longterm results is needed.
