Hydranencephaly is congenital absence of the cerebral hemispheres which are replaced by a large fluid-filled cavity. The brain stem and basal ganglia are well formed and rudiments of frontal k occipital cortex may be present. We experienced a case of hydranencephaly caused by both internal carotid artery stenosis. We diagnosed it through the brain CT sonogram and doppler sonogram. A brief review of the related literatures was made.

PURPOSE: This study was conducted to identify the effects of depression on the survival of patients with cancer over a 10 year period. METHODS: A retrospective review was conducted to examine survival of 218 patients with stomach, colorectal and breast cancer, who had been treated for cancer from 2002 to 2011. Depression was assessed by using the Symptom Check List-90 Revision in 2002, and hope, fighting spirit and other potential confounders were also measured to control for their effects on the association between depression and the survival time. Data on survival were collected from the Statistics Korea and also from medical record in 2011. Kaplan-Meier survival analysis and Cox proportional hazard regression model were used to examine if depression affected survival. RESULTS: The total number of death was 106, and the non-survivors scored higher on depression than survivors. Depression was found to be one of the influencing factors on survival from cancer. CONCLUSION: Depression was significantly associated with the increased risk of death in cancer patients. Further research is needed to identify in details which type of emotional interventions can extend the survival time of cancer patients in depression.

PURPOSE: Conventional indomethacin therapy(0.2mg/kg every 12 hours for three doses) has been used for closure of PDA. The effect of prolonged low dose of indomethacin therapy(0.1mg/kg daily for six days)had been reported in foreign country but, nothing had been reported in our country. So we attempted this study to examine effects of these two methods. METHODS: Forty one infants with PDA of prematurity from January 1992 to July 1995 who were admitted in NICU of Il Sin Christian Hospital were included. 27 of these infants received conventional dose of indomethacin therapy and 14 received prolonged low dose of indomethacin therapy, and we examined with closure rate and complication etc. RESULTS: 1) Closure of PDA was observed in 15(55.6%) and relapse was 3(11.1%) in conventional dose therapy group. In prolonged low dose therapy group, closure was 8(57.1%) and relapse was none. 2) Intraventricular hemorrhage was observed in 20(74.1%), 6(42.9%) and gastrointestinal tract bleeding was 6(22.2%), 13(92.2%) in each group. There was statistically significant between the two groups(p<0.05). 3) The rise of serum BUN, creatinine was observed in 9(33.3%), 6(46.2%), bleeding tendency was 9(33.3%), 8(57.1%), necrotizing enterocolitis was 2(7.4%), 0 and retinopathy of prematurity was 8(29.6%), 3(21.4%) in each group.But there was not statistically significant correlation between the two groups. 4) The development of sepsis and broncopulmonary dysplasia was slightly more in prolonged low dose therapy group. 5) The reduction of urine output was observed in 11(40.7%), 2(14.3%) in each group but, absolute oliguria was not observed in both groups. CONCLUSIONS: Though the closure rate of PDA was similar in both groups, prolonged low dose indomethacin therapy can be recommanded with its effectiveness on preventing the relapse of PDA and the accurrence of necrotizing enterocolitis.

PURPOSE: Failure of adequate gastric emptying frequently interferes with successful enteral nutrition in infants. Study of gastric emptying in preterm infants has been hampered by the absence of a suitable and, valid technique, but ultrasonic assessment is well tolerated by infants. The aim of this study is to compare gastric emptying rates of breast milk and formula within preterm infants using an ultrasonic technique. METHODS: Ten infants(6 males, 4 females) were studied on 20 occasions. Median gestation of the group was 33 wks(29-38 wks), birthweight was 1506gms(850-1870gms). Each infant was receiving a minimum of 150 ml/kg/day of breast milk. We conducted the study with breast milk first and with formula milk 2 days later. With the infant in the right lateral position, ultrasonic images of the gastric antrum were obtained using the aorta bifurcational branch of superior mesenteric artery as constant landmarks. Measurements of antral cross sectional area(ACSA) were made before the feed and then sequentially, following its completion until ACSA returned to its pre-feeding state. Half-emptying time(t1/2) was calculated as the time taken for the ACSA to fall to half the maximal increment. The test was well tolerated by all subjects. RESULTS: There was a strong linear relationship between gastric volume and ACSA. The half-emptying time for breast milk was less than formula : t1/2 breast milk 32.0+/-9.8 min; t1/2 formula 45.0+/-11.6 min, P=0.0004. CONCLUSION: The data demonstrate that human milk increases gastric emptying compared to formula. This has important implications for the management of preterm infants who have feeding intolerances.

The purpose of this study was to compare the effects of different light direction, exposure times and setting times when using plasma arc light on shear bond strength of metal brackets. 240 extracted human premolars were randomly assigned to one of 16 groups. Standardized brackets were bonded to enamel using different light curing units (Plasma arc light and Halogen light), exposure times (Plasma arc light 2, 4, 6 seconds and Halogen light 20 seconds), and light directions (Vertical direction [V] and Oblique direction [O]). 8 groups were tested after 5 minutes and the remaining 8 groups after 24 hours. The metal brackets were bonded with Transbond XT. Shear bond strength was measured by a universal testing machine. The results were as follows: There were no differences between the shear bond strengths of the Vertical groups (V) and Oblique groups (O), regardless of exposure times and types of light curing units (p > 0.05). The shear bond strength of the group with 2 seconds of plasma light were significantly lower than other exposure time groups (p < 0.05). The shear bond strength tested after 5 minutes was lower than after 24 hours (p < 0.05). The Adhesive Remment Index (ARI) score showed no statistically significant difference among the different groups. The results of this study suggested that the light direction of plasma arc light had no influence on the shear bond strength of metal brackets to enamel, and exposure times more than 4 seconds produced shear bond strengths similar to those produced with a conventional halogen curing light.

A ruptured brain arteriovenous malformation (bAVM) presenting with a hematoma may have unseen parts of the shunts in diagnostic angiography in the acute phase, which may lead to innate incomplete evaluation for the whole angioarchitecture of the bAVM. Even though it is generally accepted that the nidus of a ruptured bAVM may be underestimated in angiography during the acute phase due to hematoma compression, documentation of the underestimated parts has not been described in the literature. The authors report 2 cases of ruptured bAVMs in which the obscured segments were cast with liquid embolic material, which suggests a potential presence of obscured segments in bAVMs.

Cancer of the vulva accounts for approximately 0.5% of all gynecologic malignancies. At diagnosis, one-third of these cases is detected in an advanced stage (FIGO stages III, IV), and local extension of primary vulvar cancer may involve adjacent midline structures such as the clitoris, urethra, vagina, and anus. Initial surgical therapy of such locally advanced primary cancers may compromise the functional integrity of midline structures, necessitating ultraradical surgery including pelvic exenteration. In view of the relatively elderly age of the patients and the morbidity of this ultraradical dissection, concomitant chemoradiation therapy - that the efficacy had been proven in head and neck cancer, anal cancer has approached for patients with locally advanced vulvar cancer. We experienced a case of stage III vulvar cancer patient, who underwent concomitant chemoradiation therapy with 5-fluorouracil(FU) and cisplatin and who showed complete response. So, we report this case with brief review of the literatures.

BACKGROUND: This study was performed to investigate the clinical usefulness of acute normovolemic hemodilution to reduce homologous transfusion in revision total hip arthroplasty. To avoid complications of homologous transfusion, many methods are being used in patients who undergo an operation, and autologous transfusion is the most popular modality. METHODS: Fifty-five patients operated on for revision THRA were reviewed. In the hemodilution group (n = 21), 2-4 units of autologous blood were procured immediately after anesthetic induction while Ringer's lactate and 6% Haes-steril were infused to maintain normovolemia. Differences in the amounts of transfusions and postoperative drainage were compared. Statistical analyses were performed by using the Student's t-test. RESULTS: No significant differences were observed between groups in terms of preoperative hematocrit and hematocrit at postoperative 7 days. However, in the homologous transfusion group, 10.1 +/- 3.2 units of RBC products were used in 34 patients. In the autologous transfusion group, 7.5 +/- 2.6 units of RBC products were transfused in 21 patients. And this difference in RBC produce usage was significantly different (P < 0.05). The amount of postoperative wound drainage in the two groups was comparable. CONCLUSIONS: ANH could reduce the reqirement for homologous transfusion in revision total hip arthroplasty.

BACKGROUND/AIMS: Markers of inflammation have been associated with outcomes in various cancers. The purpose of this study was to evaluate whether systemic inf lammatory markers and their f luctuations can predict survival and chemotherapy response in patients with metastatic gastric cancer (mGC). METHODS: We retrospectively reviewed the records of 502 patients who received first-line palliative chemotherapy for mGC between 2007 and 2013. The neutrophil-to-lymphocyte ratio (NLR) and modified Glasgow prognostic score (mGPS) were assessed before and after chemotherapy to evaluate their association with survival. The NLR values were categorized into two groups based on a cut-off value of 3; mGPS values were classified as high versus low. RESULTS: High prechemotherapy NLR was significantly associated with poor overall survival on univariate analysis (p = 0.002). On multivariate analysis, high prechemotherapy NLR (hazard ratio, 1.43; p < 0.001) was an independent prognostic factor for poor overall survival. However, the prechemotherapy mGPS was not significantly associated with survival. Continuously high NLR or a shift to high NLR postchemotherapy was associated with poor chemotherapy response as well as survival, while NLR reduction was associated with a good response (linear by linear association, p < 0.001) and a favorable prognosis. CONCLUSIONS: Prechemotherapy NLR can be used as a prognostic factor in mGC, while the postchemotherapy NLR value may predict the chemotherapeutic response and prognosis. In contrast, mGPS has limited prognostic utility in mGC.

BACKGROUND: Intracerebral hemorrhage (ICH) is associated with a considerable proportion of stroke and head injuries, but except for supportive care, there is no medical therapy available. Transplantation of human neural stem cells (NSCs) can be used to reduce behavioral deficit in experimental ischemic infarct model. However, effect of stem cell transplantation in experimental intracerebral hemorrhage (ICH) is unknown. We hypothesized that NSCs could migrate and differentiate into neurons or glial cells, and improve functional outcome in ICH. METHODS: Experimental ICH was made by intrastriatal administration of bacterial collagenase in adult rats. Animals were randomized to receive intravenously either immortalized Lac-Z positive human NSCs (5x1 06 in 500microL, n=15) or same volume of saline (n=12) on the following day. Animals were evaluated for 8 weeks after surgery with behavioral test battery. After 8 weeks, animals were sacrificed and the brains were sectioned. Transplanted NSCs were detected by X-gal histochemistry or beta-gal immunohistochemistry, and differentiation of grafted NSCs were evaluated by double labeling of GFAP, NeuN, or neurofilament. RESULTS: Transplanted NSCs migrated to the side of peri-hematomal areas, and differentiated into neurons and astrocytes. NSCs injection group showed improved performances on rotarod test after 2 weeks and on limb placing test after 5 weeks compared with control group (p<0.05) and these effect persisted up to 8 weeks. CONCLUSIONS: Intravenously injected NSCs enter rat brain with ICH, and differentiate into astrocytes or neuronal cell, which lead to functional recovery. These findings show the possibility that NSCs can be used to reduce neurological deficits in the experimental ICH.
