OBJECTIVES: To explore the method and significance of prenatal counseling in cardiac surgery for fetal congenital heart disease (CHD). METHODS: The prenatal counseling should be provided by experienced CHD experts. The preliminary clinical diagnosis based on relevant data was carried out, the prognosis risk for fetal CHD was graded, and the pathophysiological process and potential hazards of the disease were analyzed. The current condition of CHD in the treatment plan, the long-term quality of life, and the special requirements of parturition in place, period and mode were described. A reliable follow-up system of the fetuses was established, the diagnosis after delivery was verified, and surgical treatment was carried out timely. RESULTS: From January 2016 to December 2018, 225 parents with fetal CHD received prenatal counseling, including 60 fetuses (26.7%) with simple CHD and 165 (73.3%) with complex CHD, among which 59 cases (98.3%) and 93 cases (56.4%) decided to continue the pregnancy, respectively. During the follow-up, 118 fetuses were born, of which 66 infants received surgical treatment within 6 months after birth, 63 infants (95.5%) recovered and 3 infants (4.5%) died. The rest 52 infants continued to be followed up. CONCLUSIONS The prenatal counseling for fetal CHD can provide the parents a comprehensive medical information about CHD, which is beneficial to making appropriate pregnancy decisions, and can turn the fetuses from unreasonable birth and passive treatment to selective birth and active treatment in CHD.

OBJECTIVE: To assess the value of fetal anteroposterior renal pelvic diameter (APD) in predicting antenatal hydronephrosis requiring surgical treatment after birth. METHODS: A total of 525 cases of antenatal hydronephrosis detected by prenatal ultrasonography (ultrasound index APD ≥ 4 mm in the second trimester and APD ≥ 7 mm in the third trimester) in Zhejiang Prenatal Diagnosis Center from June 2007 to June 2018 were retrospectively analyzed. ROC curve was used to analyze the relationship between these ultrasound indicators and the requirement for surgical treatment after birth. RESULTS: There were 162 cases (30.9%) diagnosed in the second trimester and 363 cases (69.1%) diagnosed in the third trimester; 131 cases were diagnosed pathologically after birth, of which 121 finally underwent surgical treatment. The area under ROC curve (AUC) of APD in middle pregnancy for prediction of requiring surgery 1-12 years after birth was 0.910; the cut-off value of APD was 8.45 mm with a sensitivity of 97.1%, specificity of 70.9%, positive predictive value (PPV) of 47.9%, and negative predictive value (NPV) of 98.9%. The AUC of APD in late pregnancy for prediction of requiring surgery 1-12 years after birth was 0.800; the cut-off value of APD was 12.25 mm with a sensitivity of 66.7%, specificity of 81.2%, PPV of 51.7%, and NPV of 89.1%. CONCLUSIONS APD in pregnancy can be used to predict whether the fetus with hydronephrosis needs surgical treatment after birth, and the prediction value of APD in the middle pregnancy is better.

Fetal adenocarcinoma of the lung (FLAC) is an extremely rare subtype of lung cancer, accounting for only 0.1% to 0.5% of primary pulmonary malignancy. In 2011, international multidisciplinary classification of lung adenocarcinoma developed by the International Association for the Study of Lung Cancer (IALSC), the American Thoracic Society (ATS) and the European Respiratory Society (ERS) classified FLAC as a variant of invasive adenocarcinoma. FLAC has been further divided into low-grade fetal adenocarcinoma (L-FLAC) and high-grade fetal adenocarcinoma (H-FLAC) as these two categories exhibit different clinicopathological features and biological behaviors. Here we report a case of high-grade fetal adenocarcinoma and summarize clinicopathologic features of fetal lung adenocarcinoma.

BACKGROUND: Frequency and distribution of unexpected red cell antibodies vary according to study population and method of antibody detection. The frequency and specificities of unexpected red cell antibodies were analyzed and compared in adults and children. METHODS: We analyzed the results of antibody screening and identification tests performed from November of 2008 to June of 2015 at Pusan National University Yangsan Hospital. A commercially available three-cell antigen panel, DiaCell I, II and Dia (DiaMed, Murten, Switzerland) for antibody screening, LISS/Coombs and NaCl/Enzyme card and the ID-Dia Panel (DiaMed, Murten, Switzerland) for antibody identification were used. RESULTS: Among the 91,145 adults, 1,804 (1.97%) had positive results for antibody screening test and 11,457 children, 447 (3.90%) had positive results. In adults, the most frequently detected unexpected antibody was anti-E (103 samples), followed by by anti-E&c (51 samples), anti-Lea (27 samples), and anti-Dia (27 samples). In children, anti-M (7 samples), anti-E&c (5 samples), anti-E (4 samples), and anti-D (4 samples) were most frequently detected. Among 9 pediatric patients with anti-E or anti-E&c, 5 patients were proven as hemolytic disease of the fetus and newborn. CONCLUSION: In this study, the positive rate of unexpected antibody screening in children was higher than in adults. Distribution of unexpected antibody differed between children and adults. It may be related to the frequent cardiac surgery performed in children at our hospital. No studies have been conducted in children. Our research may provide data for the frequency and characteristics of red cell antibodies in children.

BACKGROUND/AIMS: Endoscopic therapy with endoscopic retrograde cholangiopancreatography (ERCP) has been suggested as an effective diagnostic and therapeutic tool for biliary and pancreatic disorders during pregnancy. In this report, we describe our experiences with pancreatobiliary endoscopic procedures during pregnancy. METHODS: We reviewed ERCP and endoscopic ultrasonography (EUS) procedures that were performed at a single tertiary care referral center between January 2002 and October 2013. Medical records were reviewed for the procedure indication, the duration of fluoroscopy, postprocedure complications, etc. Pregnancy outcomes and fetal complications were identified by chart review and phone calls to patients. RESULTS: A total of 10 ER-CPs and five EUSs were performed in 13 pregnant patients: four of whom underwent the procedure in the first trimester, eight in the second trimester, and one in the third trimester. Indications for endoscopic therapy included gallstone pancreatitis, obstructive jaundice with common bile duct (CBD) stone, asymptomatic CBD stone, pancreatic cyst, choledochal cyst, and acute cholecystitis. Only one patient had a complication, which was postprocedural hyperamylasemia. Two patients underwent an artificial abortion, one according to her own decision and the other due to an adverse drug reaction. CONCLUSIONS: ERCP seems to be effective and safe for pregnant women. Additionally, EUS can be an alternative to ERCP during pregnancy.

Clinical features of 1 case of retroperitoneal parasitic fetus (PF) were retrospectively analyzed and Chinese literatures were reviewed. PF in China has 4 clinical features: 1) The incidence was extremely low and it was more common in infants and children. 2) The parasitic parts showed centrality. 3) The retroperitoneum and abdominal cavity were the most common parasite locations. 4) There was no gender difference in the incidence. Retroperitoneal PF should be distinguished from various benign and malignant abdominal tumors. Imaging was the optimal option for PF diagnosis and the axis bone system was its typical manifestation. Complete excision was the optimal treatment. Thick and large nutrient vessels may be found at where the placenta was attached, and should be ligated carefully. The outcome of this case was good because PF was completely excised.

To investigate the ability of composite graft of osteobalsts and deproteinized bone-titanium mesh (DPB-TM) scaffold to repair cranial bone defect. 30 rabbits were randomly divided into 3 groups. The passage 3 fetal rabbit osteoblasts were seeded into porous DPB-TM scaffolds at the density of 5 x 10(6) ml(-1) as the experimental group. The same defects were respectively reconstructed by DPB-TM or osteoblasts as the control groups. After 12 weeks, the result was evaluated by three-dimensional computed tomographic scanning, gross inspection, scanning electron microscopy, histological examination and mechanics test, respectively. In the experimental group, bone trabecula was observed to pass the defect and interface was mixed. No demarcation between the region of the bone defect and the normal bone was observed. There was plenty of new bone on the scaffold. Part of the scaffold was absorbed. In view of mechanics, the intensity of artificial bone (18.93+/-1.12 MPa) was higher than that of normal bone (16.96+/-1.60 MPa) (P<0.05). In the control groups, only fibrous tissue was observed in the defect region, there was no new bone formation. The tissue engineering bone constructed by osteoblasts and DPB-TM scaffold can be applied to the repair of bone defect.

BACKGROUND: We tested the effect of indomethacine and total spinal anesthesia on the improvement of placental flow during cardiopulmonary bypass on fetal lamb. MATERIAL AND METHOD: Twenty fetuses at 120 to 150 days of gestation were subjected to bypass via trans-sternal approach with a 12 G pulmonary arterial cannula and 14 to 18 F venous cannula for 30 minutes. All ewes received general anesthesia with ketamine. In all the fetuses, no anesthetic agents were used except muscle relaxant. Ten served as a control group in which placenta was worked as an oxygenator during bypass (Control group). The remainder worked as an experimental group in which pretreatment with indomethacine and total spinal anesthesia was performed before bypass with the same extracorporeal circulation technique as control group (Experimental group). Observations were made every 10 minutes during a 30-minute bypass and 30-minute post bypass period. RESULT: Weights of the fetuses ranged from 2.2 to 5.2 kg. In Control group, means of arterial pressure decreased from 44.7 to 14.4 mmHg and means of PaCO2 increased from 61.9 to 129.6 mmHg at each time points during bypass. Flow rate was suboptimal (74.3 to 97.0 ml/kg/min) during bypass. All hearts fibrillated immediately after the discontinuation of bypass. On the contrary, in Experimental group, means of arterial pressure reamined higher (45.8 to 30 mmHg) during bypass (p<0.05). Means of PaCO2 were less ranging from 59.8 to 79.4 mmHg during bypass (p<0.05). Flow rates were higher (78.8 to 120.2 ml/ kg/min) during bypass (p<0.05). There were slower deterioration of cardiac function after cessation of bypass. CONCLUSION: In this study, we demonstrated that the placental flow was increased during fetal cardiopulmonary bypass in the group pretreated with indomethacine and total spinal anesthesia. However, further studies with modifications of the bypass including a creation of more concise bypass circuit, and a use of axial pump are mandatory for the clinical application.

OBJECTIVETo investigate the role of EGF and TNF in the fetal wound healing process.

METHODSOn a fetal wound healing model with the maternal rabbit on 22-23 days of pregnancy (term = 31-32 days), the contents of EGF and TNF were analyzed with a RIA kit, compared to the maternal rabbit group and the adult rabbit group.

RESULTSThe EGF and TNF contents in the fetal wound were both increasing 3 days after the operation and maintained in a high level until the 7th day of the wound healing process(P < 0.05). However, the EGF and TNF contents in the maternal and adult rabbit groups were only kept at a high level during the 3 days after the surgery.

CONCLUSIONThe results are indicated that the EGF and TNF may play an important role in fetal wound healing.
