Delayed Uterine Rupture After Fetal Reduction in a Case of Cornual Heterotopic Pregnancy
SummaryObjectiveAssisted reproductive technology has contributed to the rising rate of multiple and ectopic pregnancies. We report a case of heterotopic cornual pregnancy with delayed uterine rupture despite successful fetal reduction. To our knowledge, this has not been previously reported.Case ReportA 32-year-old woman, gravida 2, para 0, had secondary infertility. She had undergone laparoscopic tuboplasty for bilateral tubal obstruction and laparoscopic bilateral salpingectomy for hydrosalpinx. Successful pregnancy was achieved after transfer of five frozen embryos for this pregnancy. At 7 weeks of gestation, routine pelvic sonography identified three gestational sacs, two in the intrauterine cavity and one in the right cornua. Fetal reduction with potassium chloride injection into the cornual pregnancy was performed at 8 weeks of gestation in a private clinic. At 13 weeks of gestation, she had sudden-onset low abdominal pain and hypovolemic shock. Emergency laparotomy revealed right cornual rupture, with a 3.4-cm translucent sac extruding into the peritoneal cavity. The uterus was repaired by simple closure of the right cornua. The twins survived the operation and were born smoothly at 34 weeks of gestation by cesarean section due to preterm labor and malpresentation.ConclusionUterine rupture can occur in women who have undergone successful fetal reduction for cornual heterotopic pregnancy
Acute Viral Hepatitis C-Induced Jaundice in Pregnancy
SummaryObjectiveAcute viral hepatitis C-induced jaundice in pregnancy is very rare and may be fatal. Here, we report a complicated case with acute hepatitis C-induced jaundice in pregnancy with successful managementCase ReportA 27-year-old pregnant woman, gravida 2, para 1, with gestational age of 36 weeks and 5 days, was referred to our hospital due to jaundice and elevated liver enzymes of undetermined cause. She had been suffering from general weakness, diarrhea and vomiting for 1 week, and jaundice with tea-colored urine for 3 days. At our medical center, acute viral hepatitis C-induced jaundice was suspected. Since her general condition deteriorated at 36 weeks and 6 days of gestation, we decided to induce labor. A male baby was born smoothly via the vaginal route, with birth weight 2,857 g, birth length 48.6 cm, and 1- and 5-minute Apgar scores of 7 and 9, respectively. Maternal condition improved dramatically after delivery and her serum liver enzymes and bilirubin levels gradually approached normal ranges.ConclusionMothers and fetuses with acute viral hepatitis C-induced jaundice during pregnancy are at great risk of mortality and morbidity. Timely termination may be one of the choices of treatment when fetal maturity has been reached and the maternal condition has deteriorated
Ring Chromosome 7 Presenting with Intrauterine Growth Restriction and Multiple Anomalies
SummaryObjectiveRing chromosome 7 is a very rare chromosomal anomaly that may have a grave prognosis. Nevertheless, the clinical features associated with ring chromosome 7 are highly variable. Here, we report a case with ring chromosome 7 and the perinatal findings.Case ReportA 32-year-old, gravida 1, para 0, woman was referred to our hospital because of intrauterine growth restriction (IUGR) and oligohydramnios at 35 weeks of gestation. Prenatal ultrasound revealed a severe IUGR fetus presenting with multicystic kidney, hydronephrosis and oligohydramnios. At parturition, the birth weight of this male infant was 1,720 g, and a battery of anomalies were also noted, including imperforate anus, hypospadia, micropenis, right cryptorchidism, severe IUGR, multiple nevi on the forehead, shoulder and left thigh, brain atrophy, right multicystic kidney, and left mild hydronephrosis. Cytogenetic study from cord blood revealed a ring chromosome 7.ConclusionRing chromosome 7 is extremely rare and our case might be the 15th and youngest case in the medical literature. Our case had multicystic kidney and imperforate anus, which have not been reported previously. Prenatal diagnosis of ring chromosome 7 is very difficult. When fetuses present with severe IUGR, oligohydramnios and multicystic kidney, chromosomal aberrations should be kept in mind, and perinatal cytogenetic workup is warranted
Burkitt's Lymphoma Mimicking a Primary Gynecologic Tumor
SummaryObjectiveBurkitt's lymphoma (BL) occurs mostly in children; bilateral ovarian involvement mimicking a gynecologic malignancy in adults is extremely rare. Here, we report a patient with BL mimicking a gynecologic tumorCase ReportA 50-year-old Taiwanese woman presented with the complaint of persistent lower abdominal distension with dull pain, easy satiety, and progressively increasing abdominal girth for 2 weeks. Amenorrhea was also noted for about 2 months, and her review of systems was negative for the common āBā symptoms associated with lymphoma. At our hospital, imaging studies revealed a huge pelvic mass (10.8 Ć8.7 cm), suggesting a large subserous myoma or an ovarian tumor. Under the impression of pelvic mass, she underwent exploratory laparotomy. Primary ovarian sex-cord malignancy with cecum involvement was impressed by the primitive intraoperative frozen section report. Subsequently, an optimal cytoreductive operation with right hemicolectomy was performed. However, final histopathologic report was an extranodal multifocal BL.ConclusionAlthough extranodal BL in ovaries is a rare condition, it should be noted in the differential diagnosis of pelvic gynecologic malignancies
Effects of Growth Hormone Treatment on Height, Weight, and Obesity in Taiwanese Patients with Prader-Willi Syndrome
BackgroundInformation regarding the efficacy of growth hormone (GH) therapy in Asian Prader-Willi syndrome (PWS) patients is lacking. We report our experience with GH treatment in children with PWS in Taiwan.MethodsForty-six PWS patients (27 males, 19 females; age range, 1 year 4 months to 13 years 7 months) who received and/or who are currently receiving GH treatment (0.1 IU/kg/day subcutaneously) for a period from 1 year to 3 years were retro-spectively analyzed. We evaluated height, weight, body mass index (BMI) and Rohrer index, before and after GH treatment.ResultsAfter patients had received GH for 1, 2 and 3 years, a significant improvement in mean height standard deviation score (SDS) was noted from ā1.24 to ā0.31 (p <0.01), 0.00 (p <0.001) and ā0.26 (p <0.001), respectively. Mean BMI SDS decreased significantly from 1.93 to 1.13 (p <0.05) after 1 year of treatment; however, no significant changes were observed afterward. Mean Rohrer index decreased significantly, from 224.2 to 186.6 (p <0.001), 178.9 (p <0.001) and 169.3 (p <0.001). No significant gender or genotype pattern differences were noted among the 4 parameters examined.ConclusionThis 3-year, retrospective study indicates that PWS patients benefit from GH therapy in height increase and improved body composition

Automated Classification Model With OTSU and CNN Method for Premature Ventricular Contraction Detection
Premature ventricular contraction (PVC) is one of the most common arrhythmias which can cause palpitation, cardiac arrest, and other symptoms affecting the work and rest activities of a patient. However, patients hardly decipher their own feelings to determine the severity of the disease thus, requiring a professional medical diagnosis. This study proposes a novel method based on image processing and convolutional neural network (CNN) to extract electrocardiography (ECG) curves from scanned ECG images derived from clinical ECG reports, and segment and classify heartbeats in the absence of a digital ECG data. The ECG curve is extracted using a comprehensive algorithm that combines the OTSU algorithm with erosion and dilation. This algorithm can efficiently and accurately separate the ECG curve from the ECG background grid. The performance of the classification model was evaluated and optimized using hundreds of clinical ECG data collected from Fujian Provincial Hospital. Additionally, thousands of clinical ECG reports were scanned to digital images as the test set to confirm the accuracy of the algorithm for practical application. Results showed that the average sensitivity, specificity, positive predictive value, and accuracy of the proposed model on the MIT-BIH dataset were 95.47%, 97.72%, 98.75%, and 98.25%, respectively. The classification average sensitivity, specificity, positive predictive value, and accuracy based on clinical scanned ECG images can reach to 97.24%, 81.6%, 83.8%, and 89.33%, respectively, and the clinical feasibility is high. Overall, the proposed method can extract ECG curves from scanned ECG images efficiently and accurately. Furthermore, it performs well on heartbeat classification of normal (N) and ventricular premature heartbeat
Transcriptome analysis of Dnmt3l knock-out mice derived multipotent mesenchymal stem/stromal cells during osteogenic differentiation
Multipotent mesenchymal stem/stromal cells (MSCs) exhibit great potential for cell-based therapy. Proper epigenomic signatures in MSCs are important for the maintenance and the subsequent differentiation potential. The DNA methyltransferase 3-like (DNMT3L) that was mainly expressed in the embryonic stem (ES) cells and the developing germ cells plays an important role in shaping the epigenetic landscape. Here, we report the reduced colony forming ability and impaire
