Resilience as a mediator of interpersonal relationships and depressive symptoms amongst 10th to 12th grade students.

BACKGROUND: The aim of this study was to explore the associations among interpersonal relationships, resilience and depressive symptoms, and to examine if resilience is a mediator between interpersonal relationships and depressive symptoms in senior high school students. METHODS: Of 463 randomly selected participants from among 3,900 high school students, 450 (97.19%) consented to and completed a structured 4-part questionnaire consisting of demographic items, Inventory of Adolescent Resilience, Taiwan Relationship Inventory for Children and Adolescents, and Center for Epidemiologic Studies Depression Scale for Children. The associations between interpersonal relations and resilience and their associations with depressive symptoms were analyzed using MPlus 8.0 software for structural equation modeling. RESULTS: Results from structural equation modeling indicate that resilience and interpersonal relationships were negatively associated with students' depressive symptoms, and resilience partially mediated the associations between interpersonal relationships and depressive symptoms after controlling for demographics. CONCLUSION: Findings support that resilience and better interpersonal relationships are protective factors against depressive symptoms in adolescents. The positive association between the two protectors implies that interpersonal relationships might increase resilience and then alleviate depression amongst adolescents.

Otocephaly.

Otocephaly is a rare lethal syndrome of microstomia, aglossia, agnathia, and synotia. This male infant was born to a 19-year-old, gravida 1, para 0, woman who received routine prenatal check-up. Polyhydramnios, low-lying ears, and proboscis were noted by sonography at 29 weeks of gestation. Amniocentesis showed a normal karyotype of 46, XY. Premature rupture of membranes and preterm labor were noted at 32 weeks of gestation. A male infant was delivered preterm and died shortly after birth. The infant showed midline proboscis and absence of mandible. The simple, soft ears were extremely low-set and were near the midline of the neck. Otocephaly is regarded as the most severe form of first arch anomalies. Prenatal diagnosis should be dependent on ultrasound analysis. In the face of polyhydramnios, otocephaly is one of the possible fetal anomalies.

Dandy-Walker syndrome with duplex kidney abnormalities in trisomy 18 - A rare case report.

OBJECTIVE: Trisomy 18 is one of the major numerical chromosomal disorders. The incidence of trisomy 18 is approximately one in 6000 live births. Dandy-Walker malformation (DWM) is the most common congenital malformation of the cerebellum, with an incidence of about one in 5000 live births. The incidence of trisomy 18 associated with DWM is rare and long-term survival rate is very low. CASE REPORT: A case involving a 39-year-old pregnant female with a case of trisomy 18 associated with DWM. CONCLUSION: The incidence of trisomy 18 associated with DWM is rare, and our report presents an unusual case that supplements our knowledge of this condition. We report a case involving a 39-year-old pregnant female with a case of trisomy 18 associated with Dandy-Walker malformation (DWM). Fetal ultrasonography showed hypoplasia of the cerebellar vermis and dilatation of the fourth ventricle and was characterized by an enlarged posterior fossa. Fetal magnetic resonance imaging showed inferior vermian hypoplasia and a large posterior fossa cyst communicating with the fourth ventricle causing high insertion of the torcular herophili, which was compatible with DWM. Furthermore, the karyotyping report revealed trisomy 18. The incidence of trisomy 18 associated with DWM is rare, and our report presents an unusual case that supplements our knowledge of this condition.

Myocardial infarction and ischemic hepatitis complicated by postpartum hemorrhage.

OBJECTIVE: To present a rare case of life-threatening postpartum hemorrhage due to uterine atony complicated by acute myocardial infarction and ischemic hepatitis. CASE REPORT: A 37-year-old parturient, gravida 1 para 0, presented with symptoms and signs of shock due to postpartum hemorrhage after delivery. Ischemic hepatitis, pulmonary edema, and adult respiratory distress syndrome developed the following morning. On the 7(th) postpartum day, she developed chest pain and was subsequently diagnosed with acute inferior myocardial infarction based on serial changes on the electrocardiogram (ECG) and myocardial enzymes. The clinical condition improved after a series of resuscitative efforts and percutaneous transluminal coronary angioplasty. CONCLUSION: The presented case demonstrated that when hypovolemic shock develops with complications of pulmonary edema or ischemic hepatitis, the possibility of cardiovascular disease should be immediately investigated and preventive measures initiated.

Cardiac arrest during emergency cesarean section for severe pre-eclampsia and peripartum cardiomyopathy.

OBJECTIVE: To present the correlation between severe pre-eclampsia and peripartum cardiomyopathy in pregnancy. CASE REPORT: A 41-year-old parturient, gravida 3, para 1, at 34 4/7 weeks' gestation, was diagnosed with severe pre-eclampsia. At the time of admission, a plain chest film disclosed bilateral pleural effusions. An emergent cesarean section was planned because of decreased fetal movement, heavy daily protein loss, and bilateral pleural effusions. During the cesarean section, she developed shock with acute respiratory failure. She underwent advanced cardiac life support and intubation with mechanical ventilator support. Peripartum cardiomyopathy was subsequently diagnosed by echocardiography. CONCLUSION: The presented case demonstrates that routine echocardiography is highly recommended for suspected peripartum cardiomyopathy in gravidas with severe pre-eclampsia and symptoms or signs of heart failure.

Pregnancy in a noncommunicating rudimentary horn of a unicornuate uterus: Prerupture diagnosis and management.

OBJECTIVE: The estimated incidence of rudimentary horn pregnancy is one in 76,000. It is a life-threatening entity with a 50% risk of uterine rupture. With advances in prenatal ultrasound in recent decades, there may be an opportunity to detect rudimentary horn pregnancy earlier, resulting in a lower incidence of maternal morbidity and mortality. Management is typically resection of the rudimentary horn and the ipsilateral fallopian tube by either laparotomy or laparoscopy. CASE REPORT: Here, we present the case of a 22-year-old woman with a suspected ectopic pregnancy of 12 weeks' gestation. Ultrasound and magnetic resonance imaging were performed as preoperative evaluations. A definitive diagnosis was made during laparotomy, and resection of the rudimentary horn pregnancy was performed. CONCLUSION: Diagnosis and management of rudimentary horn pregnancy remain a challenge. We should be alert to prenatal ultrasound with the intention of making an earlier diagnosis, thereby resulting in decreased maternal morbidity and mortality.

Successful treatment with granulocyte-colony stimulating factor for ritodrine-induced neutropenia in a twin pregnancy.

OBJECTIVE: Neutropenia developed after continuous intravenous infusion of ritodrine hydrochloride (Yutopar) for preterm uterine contractions in a twin pregnancy. We successfully returned the low neutrophil count to the normal range after discontinuation of infusion of ritodrine and treatment with granulocyte colony stimulating factor (G-CSF). CASE REPORT: A 34-year-old woman with twin pregnancy was treated with ritodrine for preterm uterine contractions at 27 weeks and 6 days gestation. Neutropenia developed after continuous intravenous infusion of ritodrine for about 4 weeks. We ceased the ritodrine infusion immediately and treated the neutropenia with G-CSF. A cesarean delivery was performed the day after cessation of the ritodrine infusion because of uncontrolled preterm labor. There were no adverse side effects or infectious complications in the mother or the newborns. The maternal neutrophil count recovered to the normal range 4 days after administration of G-CSF. CONCLUSION: Based on prior case reports and the clinical presentation of our case, G-CSF may be a useful treatment for pregnant women with ritodrine-induced neutropenia. However, more clinical studies are required to confirm the safety and efficacy of this treatment.

Chlamydia pneumoniae-related hemophagocytic lymphohistiocytosis in an adult patient with clonal karyotype abnormality.

Hemophagocytic lymphohistiocytosis (HLH) is a rare life-threatening disease characterized by a severe hyperinflammation caused by uncontrolled proliferation of activated lymphocytes and macrophages. Herein, we report a 58-year-old male who had Chlamydia pneumoniae-related pneumonia, followed by aggressive HLH. An abnormal cytogenetic profile was also detected. To our knowledge, this is the first report of an adult patient with C. pneumonia-associated HLH.

Prenatal diagnosis of a de novo 9p terminal chromosomal deletion in a fetus with major congenital anomalies.

OBJECTIVE: We describe a prenatal ultrasonography diagnosis of omphalocele and symbrachydactyly in a fetus and review the literature on prenatal diagnosis of 9p terminal chromosomal deletions. CASE REPORT: A 31-year-old woman (gravida 3, para 1) was referred for genetic counseling because a fetal omphalocele had been detected. Prenatal ultrasonography at 17+ weeks of gestational age revealed a singleton female fetus with biometry equivalent to 18 weeks with an omphalocele. In addition, symbrachydactyly was also noted in the right arm; the wrist bones as well as the metacarpals were missing. A chromosomal study was arranged for a congenital anomaly involving omphalocele. We obtained Giemsa-banded chromosomes from fetal tissue cells, and an abnormal male karyotype with a terminal deletion of the short arm of chromosome 9 at band 9p13 was noted. After delivery, the fetus showed omphalocele, symbrachydactyly, trigonocephaly, sex reversal, a long philtrum, low-set ears, telecanthus, and a frontal prominence. CONCLUSION: Prenatal diagnosis of abnormal ultrasound findings with omphalocele and symbrachydactyly should include the differential diagnosis of a chromosome 9p deletion.

Reevaluating reference ranges of oxygen saturation for healthy full-term neonates using pulse oximetry.

BACKGROUND: We compared our clinical experience with currently available reference oxygen saturation level (SpO(2)) values from the American Academy of Pediatrics/American Heart Association (AAP/AHA) neonatal resuscitation program guidelines. METHODS: We enrolled 145 healthy full-term neonates; infants showing respiratory distress and those with serious congenital anomalies were excluded. SpO(2) values at every 1 minute until 10 minutes after birth were measured and recorded. Infants were classified into the cesarean section (CS) and normal spontaneous delivery (NSD) groups for evaluating differences. The 10(th) percentiles of SpO(2) at each minute were used as the lower limits of normal oxygen saturation, and these were compared with the lowest target values recommended in the AAP/AHA guidelines. RESULTS: Overall, 130 vigorous full-term neonates (median gestational age: 38 5/7 weeks; body weight at birth: 2405-3960 g) were analyzed. The median SpO(2) were 67% and 89% at the 1(st) and 4(th) minute, respectively. On average, SpO(2) values reached >90% at the 5(th) minute. No statistical differences were noted in the SpO(2) values between the CS and NSD groups after 5 minutes; however, a trend of higher SpO(2) was observed in the NSD group. We noted a gradually increasing trend for SpO(2) values over time, similar to that noted in the AAP/AHA guidelines. However, SpO(2) values at the 10(th) percentiles of each minute within the first 5 minutes in our study were equal to or significantly lower than those in the AAP/AHA guidelines; moreover, at the 10(th) minute, SpO(2) values at the 10(th) percentiles were significantly higher than those in the guidelines. CONCLUSION: The delivery modes did not affect the SpO(2) values of full-term healthy neonates. Discrepancies in SpO(2) changes in full-term neonates not requiring resuscitation between this study and the AAP/AHA guidelines were significant. SpO(2) ranges for each time point within the first 10 minutes after birth should therefore be reevaluated locally.

Sublingual vaccination with sonicated Salmonella proteins and mucosal adjuvant induces mucosal and systemic immunity and protects mice from lethal enteritis.

Salmonella enteritidis is one of the most common pathogens of enteritis. Most experimental vaccines against Salmonella infection have been applied through injections. This is a new trial to explore the effect of sublingual administration of Salmonella vaccines on systemic and mucosal immunity. Adult BALB/c mice were sublingually vaccinated with sonicated Salmonella proteins (SSP) alone, or plus adjuvant CpG DNA (CpG) or cholera toxin (CT). They were boosted 2 weeks later. Saliva specific secretory IgA (SIgA) antibody responses were significantly stimulated in the mice vaccinated with SSP only or together with CpG or CT. Whereas the mice sublingually vaccinated with SSP and CpG had higher spleen cell IFN-γ production and serum specific IgG2a antibody responses, those receiving SSP and CT showed enhanced spleen cell IL-4, IL-5 and IL-6 production, and serum specific IgG1 antibody responses. After oral challenge with live S. enteritidis, the same strain of the source of SSP, immune protection in those sublingually vaccinated with SSP and CpG or CT was found to prevent intestinal necrosis and to render a higher survival rate. In conclusion, sublingual vaccination together with mucosal adjuvant CpG or CT is a simple but effective way against enteric bacterial pathogens.

Cryptic unbalanced translocation t(17;18)(p13.2;q22.3) identified by subtelomeric FISH and defined by array-based comparative genomic hybridization in a patient with mental retardation and dysmorphic features.

Molecular cytogenetics allows the identification of cryptic chromosome rearrangements, which is clinically useful in mentally retarded and/or dysmorphic individuals with normal results from conventional cytogenetics analysis. We report on a 3-year-old girl with mental retardation, growth deficiency, speech delay, and dysmorphic features including hypertelorism, upslanting palpebral fissures, midfacial hypoplasia, and posteriorly rotated ears. The G-banding analysis showed a 46,XX,t(3;8)(q26.2;p21.1)mat karyotype. However, her clinical features were suggestive of the 18q syndrome. Subtelomeric FISH analysis revealed a der(18) translocated material from chromosome 17. Array-based comparative genomic hybridization (array-CGH) with subtelomeric BAC and PAC clones confirmed the abnormality and refined the breakpoints to 18q22.3-qter and 17p13.2-pter (deletion of 8.5 Mb and duplication of 3.9 Mb, respectively). This case demonstrates the diagnostic utility of combining conventional cytogenetics with molecular chromosome analyses for the identification of subtle chromosome abnormalities.
