Although prenatal and neonatal intensive care in recent years improved survival of infants, the risk of cerebral palsy (CP) in infants with perinatal asphyxia persisted. Screening criteria for risk factors of cerebral palsy and delayed development (DD) in term infants with perinatal asphyxia are required so that early diagnosis and rehabilitation and physical therapy could decrease the neurologic complications and maximize quality of life. To identify the risk factors of CP and DD in infants with perinatal asphyxia, we undertook a case-control study of 25 infants with perinatal asphyxia (5 min Apgar score below 6). At one year follow-up, 12 infants developed CP and DD and 13 control infants showed normal development. Risk factors associated with an increased risk of CP and DD were the number of abortion (p=0. 031), history of neonatal seizure (p=0.021), hypoxic ischemic encephalopathy (p=0.046), and poor response to resuscitation immediately after birth (p=0.017). In term infants with perinatal asphyxia, the risk factors of CP and DD were increased number of abortion, history of neonatal seizure, and hypoxic ischemic encephalopathy and poor response to resuscutation. Thus infants with these risk factors should be carefully followed up after hospital discharge and further extensive and prospective study in term infants with perinatal asphyxia could elucidate possible mechanisms related to cerebral palsy and delayed development.

PURPOSE: The purpose of this study was to examine 2-year follow-up results of cytoreductive surgery (CRS) and intraperitoneal chemotherapy (IPC) for peritoneal carcinomatosis (PC) of colorectal cancer. METHODS: We performed 54 cases of CRS and IPC in 53 patients with PC of colorectal cancer from December 2011 to December 2013. We collected data prospectively and analyzed the grade of PC, morbidity and mortality, and short-term follow-up (median, 10 months; range, 2–47 months) results. RESULTS: Mean peritoneal cancer index (PCI) was 15 (range, 1–35), and complete cytoreduction was possible in 35 patients (64.8%). Complications occurred in 25 patients (46.3%) and mortality occurred in 4 patients (7.4%). Excluding the 4 mortalities, 17 patients out of 49 patients (31.5%) were alive at the time of the last follow-up and the overall median survival was 10.3 months. Patients with complete cytoreduction had a median survival of 22.6 months, which was significantly longer than the median survival of 3.5 months for patients without complete cytoreduction (P < 0.001). PCI grade, CCR grade, cell type, and postoperative chemotherapy were significant prognostic factors by univariate analysis. Positive independent prognostic factors by multivariate analysis included PCI grade and postoperative chemotherapy. CONCLUSION: CRS and IPC increased the survival of patients with low PCI and postoperative systemic chemotherapy was mandatory. However, this combined therapeutic approach showed high rate of complications and mortality. Therefore, this aggressive treatment should be performed in only selected patients by considering the general condition of the patient and the extent of PC.

We report a case of urinary bladder perforation during colonoscopy. A 67-year-old female, who had undergone a transabdominal hysterectomy for uterine myomas 15 years ago, visited the emergency department with complaint of abdominal pain after a screening colonoscopy. Laparoscopic examination revealed severe adhesion between the sigmoid colon and the urinary bladder. The urinary bladder wall was weakened, and several perforation sites were found. The surgery was converted to a laparotomy. After a thorough examination, we performed primary repair for the perforation sites, followed by an omentopexy.

Congenital fiber type disproportion (CFTD) has been related with mutations in ACTA1, SEPN1, RYR1 and tropomyosin 3 (TPM3) genes. Particularly, TPM3 mutation was identified as one of the most frequent cause of CFTD and was also detected in cap myopathy and nemaline myopathy. Herein we report patients of autosomal dominant TPM3 missense mutations with CFTD in a Korean family over twogenerations. Two of our patients, who developed mild muscle weakness in infancy, presented with altered mentality and respiratory distress despite relatively mild limb weakness.

Ischemic stroke caused by spontaneous thrombosis of posterior inferior cerebellar artery (PICA) aneurysm has been rarely reported. A 52-year-old man presented with sudden headache, dizziness, and gait disturbance. Diffusion-weighted MRI showed acute infarction in left PICA territory. A saccular aneurysm with internal thrombus at the distal PICA was detected by CT angiography and conventional angiography. The thrombus resolved spontaneously at 2 months after stroke onset with aspirin medication. At that time, endovascular coiling was underwent successfully to prevent aneurysmal rupture.

Many kinds of degenerative, psychiatric, and cerebrovascular diseases can mimic behavioral variant frontotemporal dementia. We present a 73-year-old woman who presented with apathy, inappropriate social behavior, and persecutory delusion. A neuropsychological examination revealed frontal/executive dysfunction with relative sparing of episodic memory. Magnetic resonance imaging and F-18 fluorodeoxyglucose positron-emission tomography produced normal findings. However, magnetic resonance angiography revealed severe right internal carotid stenosis. After carotid stenting, her behavioral symptoms disappeared and did not recur during an 18-month follow-up.

PURPOSE: We previously reported modified bovine lung surfactant YY-38(Newfactan ) had a low surface tension, good hysteresis, and exhibited good pressure-volume curve in animal experiment(J Korean Pediatr Asso 1997;40:771-85). We performed multicenter clinical trial of Newfactan in neonatal RDS. METHODS: Seventy-seven infants with RDS(GA 31.8+/-2.9 wks and BW 1,809+/-592 gm) in 4 NICU were enrolled. After administration of Newfactan , we analyzed ventilator parameters and outcomes in 71 infants excluding mortality cases(n=6), and also compared risk factors between response(n=53) and redosing group(n=18). RESULTS: Newfactan was administered at 6.8+/-7.2 hr after birth. Ventilator parameters such as FiO2, alveolar-arterial oxygen difference(a-A PO2) and oxygenation index(OI) except mean airway pressure(MAP) were significantly improved from six hours after administration. All parameters were improved at 24 hours after administration and persisted for 5 days. Outcomes were as follows; PDA(n=24), BPD(n=16), IVH(n=13), sepsis(n=9), ROP(n=7), pneumothorax(n=4) NEC(n=3), PIE(n=2), and pulmonary hemorrhage(n=1). All patients survived 30 days after birth. Redosing rate was 25%. The incidence of PDA was greater in redosing(56%) than in response group(26 %)(P=0.025). CONCLUSION: In prospective multicenter clinical trial, Newfactan was effective in the treatmentof RDS.

Prematurity, intrauterine infection and perinatal brain injury have been reported to be significant risk factors of cerebral palsy (CP). We examined the perinatal predictors of cerebral palsy and delayed development (DD) in 184 high risk infants. Thirty-five infants were diagnosed as cerebral palsy and delayed development at 12 months corrected age. Antenatal, intrapartum, and neonatal factors were prospectively evaluated in 2 groups of high risk infants compared with controls; Group A (n = 79), infants weighing less than 2,000 g; Group B (n = 43), infants weighing 2,000 g or more. In univariate analysis, there were no significant antenatal and intrapartum factors associated with cerebral palsy and delayed development in either group. We found that significant postnatal risk factors of CP in group A included sepsis (p = 0.008), BPD (bronchopulmonary dysplasia) (p = 0.028), IVH (intraventricular hemorrhage) (p = 0.042), ventriculomegaly (VM) (p = 0.001) and a longer duration of mechanical ventilation (p = 0.001); while in group B, sepsis (p = 0.047) and neonatal seizure (p = 0.027) were significant risk factors. In multivariate analysis, sepsis in group B was a moderate risk factor of CP (OR (odds ratio) 1.47; 95% CI (confidence interval) 1.02-2.13). In conclusion, neonatal sepsis may contribute to the development of cerebral palsy and delayed development. We suggest that high risk infants who have sepsis should be carefully followed for cerebral palsy and delayed development. The prevention of cerebral palsy may be feasible by decreasing neonatal risk factors such as sepsis during the neonatal period.

PURPOSE: Neonatal respiratory distress syndrome is caused by the deficiency of lung surfactant in premature babies. For the treatment of RDS at present surfactants such as Surfacten (Tokyo-Tanabe Co., Japan) and Exosurf (Wellcome Co., USA) are used. As awarded the grant from the Ministry of Science and Technology for a model research project of Medium-Technology program, we have modified (supplemented) the bovine lung extracts to get YY-38, for which we have performed physical and biological activities. METHODS: For physical properties, we performed stable microbubble test (SMR) and measured surface tension lowering activity using a pulsating bubble surfactometer. Minimum and maximum surface tensions measured at 1 and 5 minutes gave surface tension-surface area diagrams, from which compressibility at surface tension 10mN/m was also calculated. As to the biological activity, we used premature rabbit fetuses as a model for the study of pressure-lung volume relationship. The lung pathology was examined on the lung tissues subsequently obtained, and aerated area ratios were calculated based on the area measured by an image analyzer. RESULTS: The minimum surface tensions of YY-38 at 1 and 5 minutes for all different concentrations were low at 10mN/m, while the maximum surface tensions ranged from 33.01mN/m to 41.07mN/m. The surface tension-surface area curve showed a definite hysteresis at 1 and 5 minutes for all concentrations, and the surface tension fell below 10mN/m with 20% surface area compression. The compressibilities at surface tension 10mN/m at 5minutes for all concentrations were all below 0.02. In animal experiments, the mean lung volume of premature rabbit fetuses was inflated to 80.9ml/kg at maximum 30cmH2O, while the lung volume was maintained at 38.3mg/kg when the lung was deflated to 5cmH2O. The overall aerated area ratio was 45.4%. CONCLUSIONS: YY-38 formed sufficient amount of stable microbubbles and had a surface tension low enough to maintain alveolar stability and to exhibit a good hysteresis curve. In animal experiments it helped the expansion of premature lungs during inspiratory phase and was effective in the prevention of collapse during expiratory phase.
