One hundred sixty three patients were hysteroscoped for various reasons at our department over 10 year period. Ninety eight patients out of 163 who were diagnosed and treated for their intrauterine adhesions(IUAs) by hysteroscopy were analysed retrospectively. Patients were classified as having mild, moderate or severe stage of IUAs according to American Fertility Society classification. Twenty nine patients(29.6%) had mild IUAs, 43 patients (43.9%) had moderate IUAs, and 26 patients(26.5%) were classified as having severe stage IUAs. The predisposing causal factors of IUAs were abortion, full-term delivery, H. mole, pelvic tuberculosis and myomectomy in order of frequency but in eight cases no cause was identified. After hysteroscopic surgery, although high rate(83.9%) of restoration of normal menstruation was attained but term pregnancy rate was only 53.3% and rather high rate (32%) of preterm or abortion were identified and those pregnancy outcomes were correlated with the stage of IUAs. Complications of surgery consisted of uterine or bladder perforation, pulmonary edema and hemorrhage.

Spontaneous rupture of an ovarian artery aneurysm is an extremely rare, life-threatening disease and has been reported to be most highly associated with pregnancy. The current study presents a case of intraperitoneal and retroperitoneal hematoma caused by spontaneous rupture of a right ovarian artery aneurysm in a 56-year-old woman. A 56-year-old woman visited the emergency room with right lower quadrant abdominal pain. Contrast-enhanced computed tomography showed a large retroperitoneal and intraperitoneal hematoma and active extravasation of contrast medium in the right retroperitoneum. Consequently, transcatheter arterial embolization was successfully performed. Spontaneous rupture of an ovarian artery aneurysm should be suspected in multiparous women with abdominal or flank pain even if it is unrelated to pregnancy. Suspicion of this entity is needed for earlier diagnosis and management.

The course of diabetic retinopathy following cataract extraction was studied prospectively in 45 eyes of 33 diabetics for 4-50 weeks(average duration: 20 weeks). The results were as follows: 1. Twenty two(81.4%) of the 29 eyes with preoperative existence of diabetic retinopathy showed a statistically higher incidence of postoperative progression of diabetic retinopathy than eight(50%) of the 16 eyes with no pre-existing diabetic retinopathy(p<0.05). 2. Ten(83.3%) of the 12 eyes with posterior chamber lens in the sulcus showed a statistically higher incidence of postoperative progression of diabetic retinopathy than sixteen(55.2%) of the 23 eyes with posterior chamber lens in the bag(p<0.05). 3. The final corrected visual acuity of better than 20/40 was achieved in eleven(68.7%) of the 16 eyes with no pre-existing diabetic retinopathy and in ten(58.8%) of the 17 eyes with nonproliferative diabetic retinopathy. It revealed no significant difference between them(p>0.05). 4. Nephropathy is the most common preoperative systemic disease and eighteen of the 19 eyes showed the postoperative progression of diabetic retinopathy. There was no statistically significant difference regarding fasting blood sugar, pp2hr, HbA1c, total cholesterol, triglyceride, or the presence of hypertension, atherosclerosis, cardiac disease, and anemia. The only significant difference was related to the presence of nephropathy(p<0.05).

OBJECTIVE: Acute basilar artery occlusion (BAO) is associated with severe neurological dysfunction and high mortality rates. The benefits of mechanical thrombectomy in BAO have not been explored in recent clinical trials. Therefore, we analyzed outcomes of stent retriever mechanical thrombectomy for BAO, and compared with anterior circulation occlusions (ACO). METHODS: In total, 161 consecutive patients (24 BAO, 137 ACO) who underwent mechanical thrombectomy with the stent retriever between January 2013 and August 2016 enrolled in our study. All patients underwent clinical assessment with the National Institutes of Health Stroke Scale (NIHSS) and modified Rankin scale (mRS). Radiological results were used to evaluate thrombolysis in cerebral infarction (TICI) scores and successful recanalization was defined by TICI 2b or 3. RESULTS: Mean NIHSS scores at 24 hours and 30 days were significantly higher in the BAO group than the ACO group (p=0.021, p=0.001). mRS at 90 days was significantly higher in the BAO group (4.2) compared with the ACO group (3.0) (p=0.003). The BAO group (2.0) performed fewer stent retriever passages than the ACO group (2.7) (p=0.049). There were no significant differences between the two groups in terms of complications, but the BAO patients experienced a higher mortality (16.6%) rate than ACO patients (5.8%) (p=0.001). In subgroup analysis of BAO, patients with short procedure times achieved successful recanalization (p=0.001) and successfully recanalized patients exhibited more favorable mRS at 90 days (p=0.027). CONCLUSION: In our study, mechanical thrombectomy of BAO patients showed worse clinical outcome and higher mortality rate than ACO patients. However, mechanical thrombectomy with a stent retriever in BAO is an effective treatment, because successfully recanalized patients showed good clinical outcome in BAO patients.

STUDY DESIGN: Retrospective chart review. PURPOSE: To assess whether spontaneous reduction of spondylolisthesis, as seen on magnetic resonance imaging (MRI), is related to the degree of segmental instability and low back pain. OVERVIEW OF LITERATURE: The flexion-extension radiographs obtained in the sagittal plane are frequently used when segmental instability of spondylolisthesis is evaluated. METHODS: We retrospectively reviewed 137 patients and measured the differences of the percentage of sagittal translation and sagittal angulation to determine the segmental instability between the flexion and extension radiographs, and the spontaneous reduction on MRI. We then compared the degrees of segmental instability and the degrees of spontaneous reduction. To assess the effect of low back pain on segmental motion in regards to the flexion-extension radiographs, we compared the preoperative visual analogue scales (VAS) score for low back pain between the more and the less spontaneous reduction groups. RESULTS: The mean degree of spontaneous reduction was 5.2%. A statistically significant correlation was found between the sagittal translation on the flexion-extension radiographs and the degree of spontaneous reduction (r = 0.557, p < 0.001) and between the sagittal angulation on the flexion-extension radiographs and the degree of spontaneous reduction (r = 0.215, p = 0.012). The preoperative VAS scores for low back pain of the more spontaneous reduction group and the less spontaneous reduction group were 4.6 and 3.6 points, respectively, and this difference was statistically significant (p = 0.002). CONCLUSIONS: Spontaneous reduction of spondylolisthesis on MRI was found to be closely related to segmental instability, and the degree of spontaneous reduction seen on MRI could be useful for the evaluation of segmental instability in patients with spondylolisthesis, especially with severe low back pain.

Mixed connective tissue disease (MCTD) was first described by Sharp and coworkers in 1972, characterized by symptoms of Raynaud's phenomenon or swollen hands, overlapping clinical features of systemic lupus erythematosus, systemic sclerosis, or polymyositis/dermatomyositis, and the presence of anti-U1 RNP antibody. MCTD is rare in children and constitutes 0.3~0.6% of all rheumatologic patients in pediatric rheumatology database of the United States. Here, we report the first Korean case of a 10-year-old female patient with MCTD, presenting Raynaud's phenomenon in the hands, feet, and tongue.

Plasmodium vivax reemerged in 1993. It has been sustained for more than 25 years and become one of the important indigenous parasitic diseases in northern and western parts of the Republic of Korea near the demilitarized zone. In particular, relapse is a significant concern for the control of malaria, as short- and long-term incubation periods vary among those infected in Korea. In this study, the prevalence of asymptomatic carriers was examined among residents of high endemic areas of vivax malaria during nonseasonal transmission of mosquitoes. Blood samples from 3 endemic regions in northwestern Korea were evaluated by microscopic examination, rapid diagnostic testing, and nested PCR to identify asymptomatic patients carrying malaria parasites in the community. However, no positive malaria case among residents of endemic areas was detected. Additionally, serological analysis was carried out to measure antibodies against 3 antigenic recombinant proteins of P. vivax, merozoite surface protein 1-19, circumsporozoite surface protein-VK210, and liver-stage antigen (PvLSA-N), by the protein array method. Interestingly, seropositivity of sera between previous exposure and samples without exposure to malaria was significantly higher using the PvLSA-N antigen than the other antigens, suggesting that PvLSA-N can be used as a serological marker to analyze the degree of exposure for malaria transmission in endemic areas. This indicates a very low asymptomatic carrier prevalence during the nonmalaria season in the endemic areas of Korea.
