The intravenous administration of midazolam is widely used as sedative premedication for upper gastrointestinal endoscopy. We performed a study to evaluate the effectiveness and safety of midazoiam as premedication for upper gastrointestinal endoscopy. Between June 1995 and October 1995, 112 patients of diagnostic esophago-gastroduodenoseopy were enrolled in the study. The patients were recieved a bolus midazolam 0.~03mg/kg or placebo, followed by typical anesthesia. The blood pressure, pulse and oximeter values were monitored. The systolic blood pressure and heart rate were increased during endoscopy in compared with before premedication, and normalized immediately. There was no significant change of arterial oxygen saturation. Midazolam induced amnesia completely in 49.2% and partially in 27.2%, and all patients were recovered completely in 1 hour. The tolerance score is higher in the midazolam group as compared with the placebo group(p<0.05), and midazolam group would accept the same sedation for repeated endoscopies(p<0.01). We conclude that midazolam has beneficial effects as premedication for upper gastrointastinal endoscopy without significant altteration in cardiopulmonary parameters. This suggest that midazolam may be used more frequently as premedication, especially in the cases of repeated endoscopy.

We report a case of B-cell chronic lymphocytic leukemia (CLL) with trisomy 12 detected by FISH using chromosome 12 alpha-satellite Probe (Oncor , USA) in uncultured interphase cells. Chromosome studies did not produce an analyzable metaphase by standard short term culture and revealed only normal female karyotype by B cell mitogen (phorbol 12-myristate 13-acetate) stimulated 96 hr culture. The patient, a 59-year-old female, did not have hepatomegaly, splenomegaly, lymphadenopathy and any other symptoms. The peripheral blood of the patient showed marked lymphocytosis (WBC : 28,300/microL, Lymphocyte: 80%) and the diagnosis by immunophenotyping was B cell CLL:CD5, CDl9, CD2O, SmIg, HLA-DR positive.

PURPOSE: To determine the presence of cruciate ligament tears following avulsion injuries involving the ACL and PCL, and to correlate the findings with those of surgery. MATERIALS AND METHODS: Between March 1997 and May 2002, avulsion injury involving the ACL or PCL was diagnosed in 19 patients. Ten of these [8 males and 2 females aged 10-51 (avergae, 27.7) years] were included in this study. We assessed the presence of cruciate ligament tears at MR imaging, correlating the findings with those of surgery. Associated intra-articular injuries, treatment methods and follow-up results were also evaluated. RESULTS: Among Seven patients with ACL avulsion injury, this was assessed at MR imaging as complete tear (n=1), partial tear (n=5), or intact (n=1), while all MR images of PCL avulsion injury (n=3) showed that this was partial tear. All imaging findings corresponded with the surgical findings. In four patients there was associated knee injury involving, respectively, tears of the medial meniscus, lateral meniscus, PCL and MCL, and popliteal ligament. CONCLUSION: Our findings showed that with one exception, patients with avulsion injury of the ACL or PCL had suffered either a partial or complete tear. MR imaging may be useful in the diagnosis of tears of the cruciate ligament which have not been noticed at surgery or arthroscopy in avulsion injuries involving the ACL and PCL.

BACKGROUND: Fanconi's anemia (FA) is an autosomal recessive disease characterized by aplastic anemia, pre-malignancy, congenital malformations and chromosome breakage syndromes. As up to 30% of patients have no detectable congenital anomalies, the modern diagnosis of FA rests on chromosomal breakage of patient's cells induced by chemical clastogens such as diepoxybutane (DEB) or mitomycin-C (MMC). METHODS: We have done chromosome breakage test to differentiate FA from 11 aplastic anemia, three Diamond-Blackfan syndrome, three myelodysplastic syndrome, one acute leukemia with congenital anomaly and three siblings of FA. The peripheral blood lymphocytes from each individual were co-cultured in phytohemagglutinin-containing medium by the three methods, i.e., DEB treated, MMC treated and un-treated. RESULTS: Five cases were found to have increased chromosomal breakages to DEB and MMC, confirming diagnosis of FA. Other 21 cases showed no increased chromosomal breakages. No overlap was found between FA group and others (P<0.01). In one FA, there was no increased spontaneous breakage, but increased breakage to DEB and MMC. Of five FA, one case showed no congenital anomalies. CONCLUSIONS: Chromosme breakage test was shown to be simple, reliable and useful in ascertaining the diagnosis of FA.

In our previous study, we observed that hydrosalpingeal fluid (HSF) adversely effect mouswe embryo development and hatching. The aim of this study was to evaluate the effect of HSF as assessed by the blastocyst development rate (BDR) and by cell counting in vitro HSF was collected from nine patients undergoing salpingoneostomy to correct hydrosalpinx. Two-cell embryos were obtained from superovulated ICR mice. T6 medium and T6+/-0.4% bovine serum albumin were used as control media. T6 medium containing 10% or 50% HSF and 100% HSF from each patient were used as test media. Nine to 15 embryos were cultured in microdrops prepared from each of these media. To assess the total cell number within each blastocyst, the blastocysts were fixed and stained with Hoechst 33342 to facilitate cell counting. The mean BDR in two control media were 88.89% and 85.40%. The mean BDR in media containing 10%, 50%, 100% HSF were 85.87%, 89.58% and 75.57%, respectively (*: p<0.05). The overall mean cell count (+/-SEM) in control media were 87.6+/-9.65 and 90.12+/-11.38. The BDR was affected adversely only by 100% HSF and not in media containing 10% or 50% HSF. Mean cell counts were decreased significantly only in blastocysts cultured 100% HSF (63.8+/-13.66; p<0.01) but not in blastocysts cultured in 10% or 50% HSF (91.3+/-12.44 and 82.9+/-18.27, respectively). Thus, it is concluded that HSF has no embyotoxic effect but has a mildly negatively effect on embryonic growth and development.

Vibrio damsela was isolated from a wound infection of a 71 year-old patient with chronic renal failure. She complained of severe pain, swelling and erythema in her right hand and fingers, which developed after a puncture injury by a crab, Portunus trituberculatus. Her wound infection was improved after pus drainage and antibiotic therapy. This represents the first reported case of wound infection due to V. damsela in Korea.

Bacillus Calmette-Guerin(BCG) has been widely used for the prophylaxis of superficial bladder tumor recurrence and for the treatment of bladder carcinoma in situ. More than 95% of patients who receive BCG instillation tolerate the treatment well and side reactions have been reported in less than 5% of patients. Most side effects are minor and self-limiting. However, a rear occurrence of severe systemic reactions have been reported. Among the severe systemic reactions, hypersensitivity pneumonitis should be considered in patients with pneumonic complications after BCG instillation in cases where the culture for mycobacteria is negative in the sputum, brochoalveolar lavage and blood specimen. In addition, a fiberoptic bronchoscopy with transbronchial lung biopsy demonstrates a fibrosis of the alveolar septums, where there is and an increased lymphocyte count without tuberculous inflammatory changes, the and CD4:CD8 ratio is increased and no symptomatic response to antituberculosis chemotherapy is observed. Here we report a 68 years old man with interstitial pneumonitis following intravesical BCG instillation.

The digital impression technique has been developed for more precise restorations and convenient procedures in prosthodontic treatment compared to the conventional impression technique. Along with the utilization of CAD/CAM, the introduction of digital impression technique actualizes the digitalization of dental treatments. This case is to compare two different prostheses introducing each procedure in detail; one from CAD/CAM after taking digital impression and the other from the conventional technique. A 22-year-old female visited the clinic with the chief complaint of correction of discoloration and shape on maxillary right central incisor. Due to the trauma 8 years ago, the tooth was endodontically treated with post and resin core. The treatment was planned and the procedures were conducted under the patient's consent to treat the tooth with all ceramic crowns in two different ways for comparison. In conclusion, both prostheses presented clinically acceptable results with comparing the internal fitness of two all ceramic crowns. The prosthesis from digital impression, however, showed more errors in respect of internal fitness.
