BACKGROUND: It is a routine practice that High Frequency Jet Ventilation (HFJV) is applied through a 14~16 gauge (about 12 French (Fr.)) angiocath. The 14 Fr. suction catheter which is similar to angiocath in its internal diameter is commonly available in the operating room. We evaluated the suction catheter as a carrier of HFJV in point of ventilation, oxygenation and operating field during HFJV at microlaryngeal endoscopic surgery (MES). METHODS: Fifteen adult patients undergoing HFJV via 14 Fr. suction catheter during MES were studied. Time-based arterial blood gas analyses were done before and after HFJV. The movement of operating field was examined using laryngoscopic examination by surgeon and anesthesiologist. We also evaluated complications such as abdominal distension, barotrauma and so on. RESULTS: The mean arterial oxygen tension was maintained above 250 mmHg all the time during HFJV. The mean carbon dioxide tension was less than 51 mmHg. There were no remarkable catheter movement and complications. CONCLUSION: The 14 Fr. suction catheter is a good replacement of angiocath. It provided good operating field, ventilation and oxygenation without complications.

This study was performed to examine the combined effects of L-carnitine and isoflavone supplementation on weight reduction and body fat distribution in overweight women. Overweight/obese women (body mass index > 23 kg/m2) who were not diagnosed any type of diseases were included in this study and sixty subjects (41.1 +/- 1.5 years, 25.9 +/- 0.3 kg/m2) were randomly assigned to a placebo (n = 30) or a supplement group (n = 30, L-carnitine 300 mg + isoflavone 40 mg/day). We measured anthropometric parameters, abdominal fat distribution by computerizd tomography and blood components before and after the 12 week intervention period. After the 12 weeks of supplementation, subjects in L-carnitine and isoflavone supplement group showed a significant reduction of body weight (p < 0.001), body fat % (p < 0.05), and waist to hip ratio (p < 0.01) whereas placebo group did not show any changes. In a CT-scanned results, total fat area at L4 level was significantly reduced by 8.1% (p < 0.01) with the reduction of visceral fat area (-11.1%, p < 0.001) and subcutaneous fat area (-7.0%, p < 0.05) in the supplement group. The supplementation of L-carnitine and isoflavone showed the significant improvement of HDL-C (p < 0.01) and apoB (p < 0.05) concentrations, however, change values in those markers were not significant compared with those of the placebo group. In addition, a significant increase of adiponectin level (p < 0.001) was observed in the supplement group after the intervention. The result of present study demonstrated that supplementation of 300 mg L-carnitine and 40 mg isoflavone per day for 12 weeks can give beneficial effects on weight reduction and visceral fat accumulation. These potential antiobesity supplement can produce more favorable effects when combined with lifestyle modification.

PURPOSE: Local recurrence is a major concern in patients who have undergone surgery for ductal carcinoma in situ (DCIS). The present study assessed whether the expression levels of hormone receptors, human epidermal growth factor receptor 2 (HER2), and Ki-67, as well as resection margin status, tumor grade, age at diagnosis, and adjuvant hormonal therapy and radiotherapy (RT) are associated with recurrence in women with DCIS. METHODS: In total, 111 patients with DCIS were included in the present study. The invasive and noninvasive recurrence events were recorded. The clinicopathological features; resection margins; administration of hormonal therapy and RT; expression statuses of estrogen receptor (ER), progesterone receptor (PR), and HER2; Ki-67 expression; and molecular subtypes were evaluated. Logistic regression analysis was performed to examine the risk factors for recurrence. RESULTS: Recurrence was noted in 27 of 111 cases (24.3%). Involvement of resection margins, low tumor grade, high Ki-67 expression, and RT were independently associated with an increase in the recurrence rate (p<0.05, Pearson chi-square test). The recurrence rate was not significantly associated with patient age; ER, PR, and HER2 statuses; molecular subtype; and hormonal therapy. CONCLUSION: The results of the present study suggested that the involvement of resection margins, low tumor grade, high Ki-67 index, and the absence of adjuvant RT were independently associated with increased recurrence in patients with DCIS. Future studies should be conducted in a larger cohort of patients to further improve the identification of patients at high-risk for DCIS recurrence.

BACKGROUND: Mucinous carcinoma of the breast is an indolent tumors with a favorable prognosis; however, micropapillary features tend to lead to aggressive behavior. Thus, mucinous carcinoma and micropapillary carcinoma exhibit contrasting biologic behaviors. Here, we review invasive mucinous carcinoma with a focus on micropapillary features and correlations with clinicopathological factors. METHODS: A total of 64 patients with invasive breast cancer with mucinous or micropapillary features were enrolled in the study. Of 36 pure mucinous carcinomas, 17 (47.2%) had micropapillary features and were termed mucinous carcinoma with micropapillary features (MUMPC), and 19 (52.8%) had no micropapillary features and were termed mucinous carcinoma without micropapillary features. MUMPC were compared with 15 invasive micropapillary carcinomas (IMPC) and 13 invasive ductal and micropapillary carcinomas (IDMPC). RESULTS: The clinicopathological factors of pure mucinous carcinoma and MUMPC were not significantly different. In contrast to IMPC and IDMPC, MUMPC had a low nuclear grade, lower mitotic rate, higher expression of hormone receptors, negative human epidermal growth factor receptor 2 (HER2) status, lower Ki-67 proliferating index, and less frequent lymph node metastasis (p < .05). According to univariate analyses, progesterone receptor, HER2, T-stage, and lymph node metastasis were significant risk factors for overall survival; however, only T-stage remained significant in a multivariate analysis (p < .05). CONCLUSIONS: In contrast to IMPC and IDMPC, the micropapillary pattern in mucinous carcinoma does not contribute to aggressive behavior. However, further analysis of a larger series of patients is required to clarify the prognostic significance of micropapillary patterns in mucinous carcinoma of the breast.

Resection of large sacrococcygeal teratomas (SCTs) in premature neonates has been associated with significant perinatal mortality, making this a high risk procedure requiring careful anesthetic management. Most deaths during resection of SCTs are due to cardiac arrest caused by electrolyte imbalances, such as hyperkalemia, and massive bleeding during surgery. We describe two premature neonates who experienced cardiac arrest, one due to hyperkalemia and the other not due to hyperkalemia, during excision of large, prenatally diagnosed SCTs. We present here the considerations for anesthesia in premature neonates with huge SCTs.

PURPOSE: Valid determination of HER2 status is a prerequisite to establish an adequate treatment strategy for breast cancer patients, regardless of the disease stage. The goal of this study was to examine the feasibility of the newly developed silver-enhanced in situ hybridization (SISH) technique as an alternative to fluorescence in situ hybridization (FISH) for HER2 assay in primary invasive breast cancer. METHODS: FISH and SISH for HER2 amplification were performed using tissue microarray. Both methods were used in 257 consecutive primary breast cancers. RESULTS: HER2 amplification was observed in 62 (23.1%) of a total of 257 breast cancers based on SISH. Of the 257 breast cancers measured using both methods, the results of the two methods were consistent in 248 (concordance, 96.5%; kappa=0.903). When we compared HER2 amplification in the primary tumor with the metastatic lymph nodes of the same patients, HER2 amplification was observed in nine cases (14.0%) out of 64 cases in which HER2 was not amplified in the primary tumors. In contrast, HER2 status was completely preserved in metastatic lymph nodes showing HER2 amplification in the primary tumor. CONCLUSION: These results indicate that SISH can be a feasible alternative to FISH in the clinical setting. In node-positive breast cancer, confirmation of the HER2 status of the metastatic lymph nodes appears to be mandatory, regardless of the HER2 status of the primary tumors.

Journal of the Korean Society of Neonatology 2012;19(3):121-126
PURPOSE: Young infants with suspected sepsis routinely undergo laboratory evaluation. In particular, when an infant is a newborn baby, evaluation of the cerebrospinal fluid (CSF) has been frequently included, because the prognosis is poor, irrespectively of the etiology of meningitis. We aimed to examine the clinical predictors of CSF pleocytosis among the newborns. METHODS: We retrospectively reviewed the records of all infants, aged 30 days or younger, requiring lumbar puncture. Electronic data sources provided the demographic data of the newborns, the clinical manifestations, and all laboratory values. After a univariate analysis, logistic regression analysis was performed to predict newborns at increased risk for CSF pleocytosis. RESULTS: One hundred thirteen newborns were studied; 20 of whom (17.7%) had CSF pleocytosis. Fever was significantly associated with CSF pleocytosis (P=0.008, OR=5.08, 95% CI, 1.39-18.54). The infants with lethargic appearance also had an increased risk for CSF pleocytosis. Blood urea nitrogen level was higher in patients with pleocytosis. Logistic regression analysis revealed that other clinical features and laboratory data were not significant, except for fever and lethargy. A total of 45% of the infants with CSF pleocytosis were diagnosed with serious bacterial infection, as opposed to 19.4% of those without CSF pleocytosis. CONCLUSION: In case of neonates, it would be better to perform lumbar puncture, when the infant has fever or lethargic appearance, although, the results of routine laboratory tests were nonspecific.

BACKGROUND: Poly (ADP-ribose) polymerase (PARP) has been described as an important candidate for mediation of neurotoxicity after brain ischemia. This study was purposed to evaluate the effects of a PARP inhibitor on hypoxic-ischemic injury in the neonatal rat brain. In this study, a highly potent inhibitor of PARP, 3, 4-Dihydro-5-[4-(1-piperidinyl) butoxy]-1 (2H)-isoquinolinone (DPQ) was investigated. METHODS: Seven-day old Sprague-Dawley rat pups were used. The right common carotid artery was ligated under halothane anesthesia. After a recovery period of 3 hours, they were exposed to 8% oxygen at 37degreesC for about 120 minutes. The animals were divided into four groups: the pre-treatment group (n = 13) and post-treatment group (n = 21) were given DPQ 10 mg/kg and the pre-control group (n = 7) and post-control group (n = 14) were given a vehicle for controls. Pre-treatment and pre-control groups were injected 30 minutes prior to the hypoxic injury while post-treatment and post-control groups were injected 30 minutes after the hypoxic period intraperitoneally. The right cerebral hemisphere of the rats were examined with localized (1)H magnetic resonance spectroscopy on day 1 and 7 after the hypoxic insult. Lipid/N-acetyl aspartate (Lip/NAA) and lipid/creatine (Lip/Cr) ratios were used as apoptotic markers. On day 14, the degree of brain injury was scored by morphological changes. RESULTS: In the DPQ treated groups, the Lip/NAA and Lip/Cr ratios were lower than those of the control groups on day 1 after the hypoxic-ischemic injury (P < 0.05). However on day 7, only the ratios of the pre-treatment group were lower than those of the control group (P < 0.05). The degree of morphological changes of the brain injury on day 14 were lower in the DPQ treated groups (P < 0.05). CONCLUSIONS: These results suggest that DPQ exerts a neuroprotective effect in cerebral hypoxic-ischemic injury probably by inhibiting apoptosis especially in the early stage after an insult. Acute inhibition of PARP can have a therapeutic value in preventing ischemic brain injury.

A 4-year old boy with supravalvular ascending aortic stenosis underwent sliding aortoplasty. After cardiopulmonary bypass weaning, aorta suture site was torn accidentally and the patient was in hypovolemic shock. Emergency cardiopulmonary bypass was reinstituted and the aorta was repaired. After removal of the aortic clamp, bradycardia and hypertension were noted. We suspected increased intracranial pressure due to hypoxic brain damage after massive blood loss and the patient was treated to lower the intracranial pressure. Physicians should be aware of the significance of the hemodynamic change associated with increased intracranial pressure to prevent further neurologic damage.
