OBJECTIVE: Conization is used for diagnosis and treatment of cervical neoplasia. Our purpose of this investigation is to determine the efficacy of loop conization for the treatment of cervical dysplasia and the significance of the clinical and histological factors used to predict residual dysplasia after loop conization. METHODS: We reviewed the charts of patients who were received conization and subsequently total hysterectomy at Kangnam St Mary Hospital during 1989 and 2000. Logistic regression and Chi-square test were used for analysis. RESULTS: Total 257 patients were included. The mean age of the patients was 44.7 years. Of these patients, 87 (33.8%) had residual disease in the hysterectomy specimens. Age, the involvement of cut surface of endocervix and exocervix, severity and extent of the lesion, and scattering lesion were associated with the residual disease. But preoperative HPV infection, which is known as the cause of cervical neoplasia was not associated with the residual disease. CONCLUSION: When the high risk factors are present, the validity of conservative treatment should be considered and more careful follow up with pap smear, HPV test and colposcopy is necessary. Because about one thirds of patient has residual disease after conization, LEEP conization should be used for diagnosis of cervical neoplasia rather than treatment.

Background: Failure of mitral valve repair sometimes may be ascribed to severe or progressive alteration of the subvalvar apparatus. The aim of this study was to evaluate the effects of new chordae formation on mitral repair. Material and Method: From March 1997 to February 1999, 26 patients underwent mitral valve repairs with new chordae formation, we compared the symptoms and echocardiographic findings checked at preoperative state, and intraoperative period, discharge, and their last OPD visit. There were 15 male , and 11 female patients, and their mean age was 51.2+/-13.4 years. Etiology of the lesions was degenerative (18), rheumatic (6), infective (1) and ischemic (1). Chordal lesions were caused by rupture (18), elongation (6), and a combination of two causes (2). Associated lesions included atrial septal defect (2), tricuspid insufficiency (7), aortic insufficiency(4), and a combination of previous two factors (2). The number of mean artificial chordae was 3.6+/-1.6. Annuloplasty was performed in all cases. The CPB time was 182.1+/-63.7 minutes and the ACC time was 133.1+/-45.6 minutes. Average follow up period was 49.2+/-7.1 months. Result: There was no early death. Early reoperation was performed in two patients, one patient received mitral valve replacement because of an abnormality of annuloplasty and another received pericardiostomy due to postoperative pericardial effusion. During the follow up of 49.2+/-7.1 moths, there was no late mortality. Postoperative NYHA functional class checked at last OPD visit was class I in 22 patients (88%), class II in 2 (8%), and class III in 1 (4%). Regarding the late echocardiogram MR was absent in 20 patients (78%), I in 4 (15%), and II in 1 (4%). The postrepair mitral valve area was 2.2+/-0.35 cm(2). Conclusion: This study suggests that mitral valve repair using new chordae formation provides good early and mid term survivals and functional improvement. We think that the artificial chorda formation with polytetrafluoroethylene suture might be safe and effective technique for mitral valve repair.

Uterine arteriovenous malformations are considered very rare conditions, potentially life-threatening lesions combined with various degrees of menorrhagia, postpartum bleeding, postmenopausal bleeding, an asymptomatic mass, and congestive heart failure. Clinical suspicion is essential for a prompt diagnosis and treatment. They may be diagnosed by gray-scale ultrasonography and Color Doppler imaging. Additionally, they can be detected using contrast material-enhanced computed tomography (CT), conventional angiography, hysteroscopy and hysterosalpingogram. More recently, diagnosis of uterine AVM with magnetic resonance imaging (MRI) has been reported. In the past, laparotomy with uterine artery ligation or hysterectomy was the only treatment available. However, successful conservative management with embolization of the affected vessels or methylergonovine maleate has been reported recently. A 37-year-old woman, gravida 3, para 1, presented with massive uterine bleeding that started abruptly four weeks after D and C. We promptly performed non-invasive diagnositic evaluations including color Doppler, MRI and MRA, with a clinical impression of uterine AVM. In this case, we describe the appropriate diagnosis and management of uterine AVMs with literatures.

OBJECTIVE: Most of the studies that have described surgical procedures for moyamoya disease(MMD) have had the aim to improve the blood flow mainly in the middle cerebral artery(MCA) territory. The purpose of this study is to clarify the good indications for a multiple burrhole operation to treat MMD. METHODS: With the patient under local anesthesia, burrhole trephination with a diameter of 1.5 to 2cm at 3 to 5cm lateral to the midline was performed in a total of 18 hemispheres during 12 procedures. The burrholes were opened in the frontal lobe at 19 sites in 10 patients and in the parietal lobe at 22 sites in 12 patients. Revascularization through multiple burrholes and arachnoid openings was performed in 12 patients who suffered from MMD. RESULTS: As seen on the follow up angiograms, good revascularization was achieved in 27 of 41 burrholes, and mainly from the middle meningeal artery and then from the superficial temporal artery. The moyamoya vessels were decreased in four patients. The neovascularization covered 68.4% of the frontal lobe and 63.5% of the parietal lobe. Compared with the preoperative 99mTc-HMPAO-SPECT, 6 patients showed improvement of cerebral blood flow on the postoperative 99mTc-HMPAO-SPECT. Transient ischemic attack disappeared in three of the four patients who presented with this symptom, and the preoperative symptoms improved in both of the patients who presented with headache and cerebral infarction. CONCLUSIONS: A multiple burrhole operation is a simple technique. The results of our series suggest that the revascularization obtained for adult MMD patients who underwent a multiple burrhole operation is similar to that obtained with other indirect surgeries, but long term follow up studies are needed.

OBJECTIVE: To identify the differences in the movement of the hyoid bone and the vocal cord with and without electrical stimulation in normal subjects. METHODS: Two-dimensional motion analysis using a videofluoroscopic swallowing study with and without electrical stimulation was performed. Surface electrical stimulation was applied during swallowing using electrodes placed at three different locations on each subject. All subjects were analyzed three times using the following electrode placements: with one pair of electrodes on the suprahyoid muscles and a second pair on the infrahyoid muscles (SI); with placement of the electrode pairs on only the infrahyoid muscles (IO); and with the electrode pairs placed vertically on the suprahyoid and infrahyoid muscles (SIV). RESULTS: The main outcomes of this study demonstrated an initial downward displacement as well as different movements of the hyoid bone with the three electrode placements used for electrical stimulation. The initial positions of the hyoid bone with the SI and IO placements resulted in an inferior and anterior displaced position. During swallowing, the hyoid bone moved in a more superior and less anterior direction, resulting in almost the same peak position compared with no electrical stimulation. CONCLUSION: These results demonstrate that electrical stimulation caused an initial depression of the hyoid bone, which had nearly the same peak position during swallowing. Electrical stimulation during swallowing was not dependent on the position of the electrode on the neck, such as on the infrahyoid or on both the suprahyoid and infrahyoid muscles.

OBJECTIVE: Surgical site infection (SSI) is a problem constantly uppermost in the minds of all surgeons, although the actual rate of occurrence is only 1-5% in general surgery. In neurosurgical fields, there have been a few papers published about efficacy of post-operative antimicrobial prophylaxis (PAMP) to prevent SSI, compared to well known effectiveness of pre-operative antibiotics. Thus, infection rates of short-term PAMP groups and those of long-term PAMP groups were investigated to evaluate the effectiveness of PAMP and the efficacy of short-term PAMP compared to long-term PAMP for prevention of SSI. METHODS: Between April 2010 and April 2012, we retrospectively analyzed the data of 35 patients in the aneurysmal neck clipping groups (short-term PAMP group: PAMP for 3 days and fewer, long-term PAMP group: PAMP for 10 days and more) and 79 patients in the microdiscectomy groups (short-term PAMP group: 3 days and fewer, long-term PAMP group: PAMP for 6 days and more). RESULTS: In aneurysmal neck clipping groups, SSI occurred 23.1% of short-term PAMP group and 9.1% of long-term PAMP group (p=0.3370). And in microdiscectomy groups, SSI occurred 6.7% of short-term PAMP group and 4.1% of long-term PAMP group (p=0.9840). CONCLUSION: There is no significant difference between the short-term PAMP group and the long-term PAMP group in terms of SSI, regardless of operation type. We therefore suggest that short-term PAMP usage could be an appropriate therapy for preventing SSI in clean neurosurgical operations.

Fetal tachycardia (FT) is a rare disorder and is associated with significant mortality of fetus. Digoxin is one of the antiarrhythmic agents used to treat FT via transplacental therapy. In this report, we describe a therapeutic drug monitoring (TDM) case of digoxin during the treatment of FT. A 40-year-old woman, gravida 2 para 1, hospitalized to control FT as the fetal heart rate (FHR) showed over 200 bpm on ultrasonography at 29 weeks of gestation. She did not have any medical or medication history and showed normal electrolytes level on clinical laboratory test results. For the treatment of FT loading and maintenance dose of intravenous digoxin (loading dose: 0.6 mg; maintenance dose: 0.3 mg every 8 hours) were administered. To monitor the efficacy and safety of the treatment, TDM was conducted with a target maternal serum trough digoxin concentration of 1.0 to 2.0 ng/mL, as well as ultrasonography and maternal electrocardiogram. The observed digoxin serum concentrations were 0.67, 0.83, and 1.05 ng/mL after 1, 2, and 5 days after the initiation of digoxin therapy, respectively. Although the serum digoxin concentrations reached the target range, the FHR did not improve. Therefore, digoxin was discontinued, and oral flecainide therapy was started. The FHR adjusted to the normal range within 2 days from changing treatment and remained stable. TDM of digoxin along with the monitoring of clinical responses can give valuable information for decision-making during the treatment FT.

The chromosome band 11q23 is a common target region of chromosomal translocation in different types of leukemia, including infantile leukemia and therapy-related leukemia. The target gene at 11q23, MLL, is disrupted by the translocation and becomes fused to various translocation partners. We report a case of AML with a rare 3-way translocation involving chromosomes 1, 9, and 11: t(1;9;11)(p34.2;p22;q23). A 3-yr-old Korean girl presented with a 5-day history of fever. A diagnosis of AML was made on the basis of the morphological evaluation and immunophenotyping of bone marrow specimens. Flow cytometric immunophenotyping showed blasts positive for myeloid lineage markers and aberrant CD19 expression. Karyotypic analysis showed 46,XX,t(1;9;11)(p34.2;p22;q23) in 19 of the 20 cells analyzed. This abnormality was involved in MLL/MLLT3 rearrangement, which was confirmed by qualitative multiplex reverse transcription-PCR and interphase FISH. She achieved morphological and cytogenetic remission after 1 month of chemotherapy and remained event-free for 6 months. Four cases of t(1;9;11)(v;p22;q23) have been reported previously in a series that included cases with other 11q23 abnormalities, making it difficult to determine the distinctive clinical features associated with this abnormality. To our knowledge, this is the first description of t(1;9;11) with clinical and laboratory data, including the data for the involved genes, MLL/MLLT3.
