Risk of uterine, ovarian and breast cancer following pelvic inflammatory disease: a nationwide population-based retrospective cohort study.

BACKGROUND: Pelvic inflammatory disease (PID) is characterized by infection and inflammation of the upper genital tract in women and is associated with health sequelae. We used a nationwide population-based retrospective cohort study to explore the relationship between PID and the subsequent development of gynecological cancers including ovarian, breast or uterine cancer. METHODS: We identified subjects diagnosed with PID between January 1st, 2000 and December 31st, 2002 in the Taiwan National Health Insurance Research Database. A comparison cohort constructed for patients without PID were matched according to age and sex. All PID patients and control groups were observed until diagnosed with ovarian, breast or uterine cancer, or until death, withdrawal from the NHI system, or until December 31st, 2009. RESULTS: The PID cohort consisted of 32,268 patients, and an equal number of matched controls without PID. The adjusted hazard ratio (HR) of ovarian, breast or uterine cancer in subjects with PID were: HR 1.326 (95 % confidence interval: 0.775-2.269), HR: 1.039 (95 % confidence interval: 0.862-1.252), and HR: 1.439 (95 % confidence interval: 0.853-2.426) respectively in comparison with controls during follow-up. CONCLUSIONS: This large nationwide population-based cohort study suggests that there is no increased risk for ovarian, breast or uterine cancer among women who have PID compared to a matching population.

A nationwide population-based retrospective cohort study of the risk of uterine, ovarian and breast cancer in women with polycystic ovary syndrome.

BACKGROUND: Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders among women of reproductive age. We used a nationwide population-based retrospective cohort study to explore the relationship between PCOS and the subsequent development of gynecological cancers including uterine, breast, or ovarian cancer. METHODS: We identified subjects who were diagnosed with PCOS between January 1, 2000, and December 31, 2004, in the Taiwan National Health Insurance (NHI) Research Database. A comparison cohort was constructed for patients without known PCOS who were also matched according to age. All PCOS and control patients were observed until diagnosed with breast cancer, ovarian cancer, or uterine cancer or until death, withdrawal from the NHI system, or December 31, 2009. RESULTS: The PCOS cohort consisted of 3,566 patients, and the comparison cohort consisted of 14,264 matched control patients without PCOS. The adjusted hazard ratio (HR) of uterine cancer and breast cancer in subjects with PCOS were higher (HR: 8.42 [95% confidence interval: 1.62-43.89] and HR: 1.99 [95% confidence interval: 1.05-3.77], respectively) than that of the controls during the follow-up. With the Monte Carlo method, only the mean adjusted HR of 1,000 comparisons for developing uterine cancer during the follow-up period was greater for the PCOS group than for the control groups (HR: 4.71, 95% confidence interval: 1.57-14.11). CONCLUSION: PCOS might increase the risk of subsequent newly diagnosed uterine cancer. It is critical that further large-scale, well-designed studies be conducted to confirm the association between PCOS and gynecological cancer risk.

An analysis of Chinese nursing electronic medical records to predict violence in psychiatric inpatients using text mining and machine learning techniques.

BACKGROUND: The prevalence of violence in acute psychiatric wards is a critical concern. According to a meta-analysis investigating violence in psychiatric inpatient units, researchers estimated that approximately 17% of inpatients commit one or more acts of violence during their stay. Inpatient violence negatively affects health-care providers and patients and may contribute to high staff turnover. Therefore, predicting which psychiatric inpatients will commit violence is of considerable clinical significance. OBJECTIVE: The present study aimed to estimate the violence rate for psychiatric inpatients and establish a predictive model for violence in psychiatric inpatients. METHODS: We collected the structured and unstructured data from Chinese nursing electronic medical records (EMRs) for the violence prediction. The data was obtained from the psychiatry department of a regional hospital in southern Taiwan, covering the period between January 2008 and December 2018. Several text mining and machine learning techniques were employed to analyze the data. RESULTS: The results demonstrated that the rate of violence in psychiatric inpatients is 19.7%. The patients with violence in psychiatric wards were generally younger, had a more violent history, and were more likely to be unmarried. Furthermore, our study supported the feasibility of predicting aggressive incidents in psychiatric wards by using nursing EMRs and the proposed method can be incorporated into routine clinical practice to enable early prediction of inpatient violence. CONCLUSIONS: Our findings may provide clinicians with a new basis for judgment of the risk of violence in psychiatric wards.

Quantification of prenatal exposure and maternal-fetal transfer of nonylphenol.

Nonylphenol (NP) is an environmental hormone commonly found in daily foodstuffs. This study examined maternal and umbilical-cord blood samples to explore prenatal exposure levels to nonylphenol and placental protection against NP exposure. One hundred and seventy-four mixed cord blood samples were collected. Among them, 42 pairs of expectant mothers and their prenatal fetus were matched to compare nonylphenol levels between mothers and fetuses. An additional 30 mother-infant dyads were chosen to give maternal, umbilical arterial and venous blood samples. Plasma samples were enzymatically deconjugated and then cleaned up with solid-phase extraction. After extraction, samples were analyzed with reversed-phase high-performance liquid chromatography coupled with fluorescence detection. Analytical results identified prenatal exposure to NPs and relatively high prenatal exposure levels in metropolitan areas. The concentrations ranged from undetectable (below 1.82 ng/g plasma) to 211 ng/g plasma. Concentrations of NP in mother-infant dyads showed the NP concentrations in maternal plasma were not definitely higher than that in fetal plasma. Still, 63.6% of NP detectable mother-infant dyads showed a higher concentration in umbilical venous plasma than those in umbilical arterial plasma. Through the repeated exposure from expectant mothers' dietary intake, fetuses could encounter high NP exposure level due to transplacental absorption, partitioning between the maternal and fetal compartments, as well as poor detoxification mechanisms of the developing organism. Some mechanisms may contribute to the reduction of NP levels in fetal blood circulation but those remain unclear.

Prenatal diagnosis of tetralogy of Fallot with pulmonary atresia.

Tetralogy of Fallot involves an abnormal embryological development in which an unequal conotruncal division results in a small pulmonary artery and a great aortic artery. In its most severe form, the infundibulum of the right ventricle and the pulmonary artery can be atretic with the anomaly commonly referred to as pulmonary atresia with ventricular septal defect. Reported here is a case of prenatal diagnosis of tetralogy of Fallot with pulmonary atresia. The characteristic ultrasonographic findings included a small pulmonary artery, a large aorta, and a ventricular septal defect. The search for an atretic pulmonary valve and a ductus arteriosus with reversed blood flow was emphasized in the presence of asymmetrically dilated fetal heart. After birth, the newborn received single-stage total correction for the tetralogy of Fallot and was discharged a month later in stable condition. In this case report, the neonatal angiogram is added for confirming the prenatal diagnosis, which is of value in teaching fetal echocardiography to novice practitioners. We believe a prenatal diagnosis of tetralogy of Fallot can improve neonatal outcome.

Hyperbaric oxygen therapy for cesarean section wound in diabetes mellitus gravida.

We report the use of hyperbaric oxygen (HBO) therapy to treat the complication of necrotizing fasciitis following Cesarean section in a postpartum gravida with diabetes mellitus. Our patient was a 25-year-old, gravida 1, para 1, woman with a history of type 1 diabetes mellitus since the age of 18. The patient experienced preterm labor at 31+1 gestational weeks and was treated with magnesium sulfate for tocolytic therapy. The patient then went into labor at 39+6 gestational weeks. She received Cesarean section due to prolonged labor associated with non-reassuring fetal status of both smooth baseline and fetal tachycardia. An ultrasound scan of the lower abdomen on the 4th postoperative day revealed fluid collection measuring 4 mm over the rectus fascia and edematous change of the surrounding soft tissues under the Cesarean section incision site. The patient eventually received HBO for a total of 7 days. Following HBO, the condition of the surgical wound improved dramatically. The results of this case showed that HBO has the potential to be a cost-effective way to enhance the healing of necrotizing fasciitis in diabetes mellitus gravida.

Lamivudine therapy in the treatment of chronic hepatitis B with acute exacerbation during pregnancy.

We report a case of chronic hepatitis B carrier gravida who had acute exacerbation during pregnancy. She had been taking lamivudine 100 mg/qd for 17 months when hepatitis B virus (HBV) DNA in the YMDD region of the polymerase gene (YMDD motif) mutant was noted. After discontinuing lamivudine, she became pregnant. HBeAg became positive again and liver enzymes were elevated during the first trimester of pregnancy. She received the hepatoprotective agent silymarin 150 mg bid at 13+2 gestational weeks. Serum aspartate aminotransferase (AST) dropped to 757 U/L at 15+0 gestational weeks, but serum alanine aminotransferase (ALT) flared up to 2,230 U/L and AST to 2,250 U/L at 17+1 gestational weeks. Serum HBV-DNA test revealed serum HBV-DNA concentration of 7.31 x 10(8) copies/mL. Lamivudine 100 mg/qd and silymarin 150 mg/bid were initiated at 17+1 gestational weeks. Liver function showed gradual decline to ALT 341 U/L and AST 91 U/L at 21+0 gestational weeks, while HBeAg(+) converted to (-) and anti-HBe(-) converted to (+). Further treatment with lamivudine 100 mg/qd continued for 3 months. Serum HBV-DNA concentrations decreased to 3.19 x 10(2) copies/mL at 36+6 gestational weeks. Spontaneous delivery of a male baby weighing 3314 g occurred at 38+3 gestational weeks. The neonatal physical check-up revealed no congenital anomalies, and fetal growth was within normal reference ranges, suggesting that lamivudine may be safely used in the treatment of chronic hepatitis B with acute exacerbation during the second trimester of pregnancy.

Prenatal diagnosis of pulmonary sequestration by ultrasound and magnetic resonance imaging.

A 36-year-old multigravida, G2P1, underwent routine ultrasound scan at 22+1 weeks of gestation, which revealed a single normally growing fetus with left intrathoracic mass and left displacement of the cardiac apex. The left intrathoracic wedge-shaped hyperechogenic mass, measuring 32 x 25 mm in size, was situated at the lower portion of the left lung. A combination of color and power Doppler ultrasound allowed visualization of a vessel arising from the descending aorta, which supplied the mass. The diagnosis of extralobar pulmonary sequestration was made. Magnetic resonance imaging (MRI) was also performed and revealed a well-defined mass with homogeneous high-signal intensity when compared with normal lung tissue in the left upper lung field, which was compatible with pulmonary sequestration. The pulmonary mass was followed up by color and power Doppler every 2 weeks. The peak velocity of 11.85 cm/sec and the diameter of the feeding artery of 1.19 mm gradually decreased and disappeared 8 weeks later. The intrathoracic mass disappeared 10 weeks later at 32+1 gestational weeks. Repeat MRI also revealed spontaneous regression of the mass in favor of resorption of sequestration. The fetus was delivered at 38+1 gestational weeks. A male newborn weighing 2,520 g was spontaneously delivered with an Apgar score of 8 at 1 minute and 9 at 5 minutes. In our patient, it is suggested that progressive decreases in the peak velocity of the feeding vessel heralded the spontaneous regression of pulmonary sequestration not associated with hydrops/hydrothorax.

Prenatal diagnosis of dextrotransposition of the great arteries.

Dextrotransposition of the great arteries (DTGA) is a common cardiac cause of cyanosis in newborn infants that can cause acidosis and death within a short period of time unless there is a large atrial-level shunt or a patent ductus arteriosus. Here, we report a case of prenatal diagnosis of DTGA at 24+1 gestational weeks. In a tilted 4-chamber view, the pulmonary trunk branched to the left and the right pulmonary, with its root connected to the left ventricle outflow tract. In the short-axis view, the pulmonary trunk was shown to be parallel with the ascending aortic root. Cesarean section was performed due to the nonreassuring fetal status at 38+5 gestational weeks. The male neonate appeared to have mild cyanotic symptoms and weighed 3,108 g. Apgar scores were 8 and 9 at 1 and 5 minutes, respectively. Neonatal echocardiography was performed immediately after birth and the findings confirmed DTGA associated with atrial septal defect secundum. Postnatally, angiography confirmed the echocardiographic diagnosis of DTGA with a large atrial septal defect secundum and a large patent ductus arteriosus. Jatene arterial switch operation and atrial septal defect closure with Gore-Tex patch were performed. The neonate withstood the operation well and was discharged 27 days after birth weighing 2,950 g and in a stable condition. Prenatal diagnosis of DTGA can greatly aid to prepare the patient's family and the surgeon and significantly improve the outcome of complex heart disease in the neonatal period.

Risk of sexually transmitted infections following depressive disorder: A nationwide population-based cohort study.

Depressive disorder is a severe mental disorder associated with functional and cognitive impairment. Numerous papers in the literature investigated associations between sexually transmitted infections (STIs) and psychiatric illnesses. However, the results of these studies are controversial.We explored the relationship between depressive disorder and the subsequent development of STIs including human immunodeficiency virus (HIV) infection, primary, secondary, and latent syphilis, genital warts, gonorrhea, chlamydial infection, and trichomoniasis.We identified patients who were diagnosed with the depressive disorder in the Taiwan National Health Insurance Research Database. A comparison cohort was constructed of patients without the depressive disorder who were matched according to age and sex. The occurrence of subsequent new-onset STIs was evaluated in both cohorts.The depression cohort consisted of 5959 patients, and the comparison cohort consisted of 23,836 matched control patients without depressive disorder. The incidence of subsequent STIs (hazard ratio [HR] 1.54, 95% confidence interval [CI] 1.34-1.76) was higher among the depressed patients than among the patients in the comparison cohort. Furthermore, female gender compared to male (HR 1.58, 95% CI 1.24-2.01) and young age <40-year-old (HR 1.79, 95% CI 1.38-2.32) are both risk factors for acquisition of STIs in depression patient. For individual STI, the results indicated that the patients with depressive disorder exhibited a markedly higher risk for subsequent STIs including HIV infection, syphilis, genital warts, gonorrhea, chlamydial infection, and trichomoniasis.Depressive disorder might increase the risk of subsequent newly diagnosed STIs including HIV infection, syphilis, genital warts, gonorrhea, chlamydial infection, and trichomoniasis in Taiwan population. Clinicians should pay particular attention to STIs in depression patients. Depression patients, especially those with the history of high-risk sexual behaviors, should be routinely screened for STIs.

Risk of sexual transmitted infection following bipolar disorder: a nationwide population-based cohort study.

BACKGROUND: Bipolar disorder is a severe mental disorder associated with functional and cognitive impairment. Numerous studies have investigated associations between sexually transmitted infections (STIs) and psychiatric illnesses. However, the results of these studies are controversial. OBJECTIVE: We explored the association between bipolar disorder and the subsequent development of STIs, including human immunodeficiency virus infection; primary, secondary, and latent syphilis; genital warts; gonorrhea; chlamydial infection; and trichomoniasis. RESULTS: The bipolar cohort consisted of 1293 patients, and the comparison cohort consisted of 5172 matched control subjects without bipolar disorder. The incidence of subsequent STIs (hazard ratio (HR) = 2.23, 95% confidence interval (CI) 1.68-2.96) was higher among the patients with bipolar disorder than in the comparison cohort. Furthermore, female gender is a risk factor for acquisition of STIs (HR = 2.36, 95% CI 1.73-4.89) among patients with bipolar disorder. For individual STIs, the results indicated that the patients with bipolar disorder exhibited a markedly higher risk for subsequently contracting syphilis, genital warts, and trichomoniasis. CONCLUSIONS: Bipolar disorder might increase the risk of subsequent newly diagnosed STIs, including syphilis, genital warts, and trichomoniasis. Clinicians should pay particular attention to STIs in patients with bipolar disorder. Patients with bipolar disorder, especially those with a history of high-risk sexual behaviors, should be routinely screened for STIs. METHODS: We identified patients who were diagnosed with bipolar disorder in the Taiwan National Health Insurance Research Database. A comparison cohort was constructed of patients without bipolar disorder who were matched with the bipolar cohort according to age and gender. The occurrence of subsequent new-onset STIs was evaluated in both cohorts.

Pregnancy complicated with maternal pulmonary hypertension and placenta accreta.

Pregnancy is contraindicated in cases of maternal pulmonary hypertension, a highly morbid disease affecting young women of childbearing age. The rate of heart failure increases gradually with the severity of pulmonary hypertension. In certain instances, the severity of maternal pulmonary hypertension in rheumatic heart diseases can be higher than in congenital heart diseases. Placenta accreta is an important cause of bleeding in the second half of pregnancy and in labor. In severe cases, hysterectomy is the only way to manage the bleeding during cesarean section. A 33-year-old gravida, G2P0AA1, suffering from rheumatic heart disease with mitral valve stenosis and pulmonary hypertension, was referred to our high-risk pregnancy center at 10(+3) weeks of gestation due to lower abdominal pain and brownish vaginal bleeding. She had received 2 mitral valve replacements in Shenzhen, China, at the ages of 22 and 26, respectively. Ultrasound scan of the abdomen at 12(+2) gestational weeks showed that the internal cervix was completely covered with the placenta, and a retroplacental hypoechoic space measuring 35 x 13 mm was observed at the upper posterior margin of the placenta. On color Doppler scan, an area of lacunar lake flow was observed in the hypoechoic space of the placenta and a spiral artery with low blood flow resistance was detected. The pulsation of the placental flow was synchronized with the maternal pulse rate. Team specialists, including neonatologists, pulmonary physicians, pediatric cardiologists, hematologists, anesthesiologists, psychiatrists and social workers, as well as high-risk obstetricians were consulted in an effort to minimize fetal and maternal morbidity and mortality. At 29(+2) weeks, the patient developed preeclampsia and delivered a healthy newborn by cesarean section, the uterus being preserved by square compression sutures. The gravida tolerated the procedures and was discharged in stable condition.

Ultrasound and magnetic resonance images of endodermal sinus tumor.

Endodermal sinus tumor, also known as yolk sac tumor, is a rare malignant ovarian tumor that usually occurs in the second decade of life. Here, we report a case of endodermal sinus tumor which occurred in a 14-year-old girl. She presented with lower abdominal pain for about 4 months. Initial ultrasound findings revealed a large ovarian multilocular solid tumor. Doppler study revealed multiple arteriole vessels running in the solid section of the tumor from which the lowest resistance index of 0.30 was recorded. The lactate dehydrogenase level was 261 U/L, and alpha-fetoprotein marker was 131,630 ng/mL. Axial contrast-enhanced T1-weighted magnetic resonance imaging showed a large cystic mass with solid components in the peripheral portions of the mass. The peripheral solid portions showed strong enhancement, indicating their hypervascularity. She received staging operation for malignant ovarian tumor, and the pathology reports revealed ovarian malignance of endodermal sinus tumor with omental invasion, stage IIIc. This case report suggests that in an adolescent female with elevated alpha-fetoprotein, low resistance index in the tumor mass and hypervascularity on contrast-enhanced T1-weighted magnetic resonance image, the probability of an endodermal sinus tumor should be highly suspected preoperatively.

Dynamic motion analysis of fetuses with central nervous system disorders by cine magnetic resonance imaging using fast imaging employing steady-state acquisition and parallel imaging: a preliminary result.

OBJECT: The authors present a novel cine magnetic resonance (MR) imaging, two-dimensional (2D) fast imaging employing steady-state acquisition (FIESTA) technique with parallel imaging. It achieves temporal resolution at less than half a second as well as high spatial resolution cine imaging free of motion artifacts for evaluating the dynamic motion of fetuses in utero. The information obtained is used to predict postnatal outcome. METHODS: Twenty-five fetuses with anomalies were studied. Ultrasonography demonstrated severe abnormalities in five of the fetuses; the other 20 fetuses constituted a control group. The cine fetal MR imaging demonstrated fetal head, neck, trunk, extremity, and finger as well as swallowing motions. Imaging findings were evaluated and compared in fetuses with major central nervous system (CNS) anomalies in five cases and minor CNS, non-CNS, or no anomalies in 20 cases. Normal motility was observed in the latter group. For fetuses in the former group, those with abnormal motility failed to survive after delivery, whereas those with normal motility survived with functioning preserved. The power deposition of radiofrequency, presented as specific absorption rate (SAR), was calculated. The SAR of FIESTA was approximately 13 times lower than that of conventional MR imaging of fetuses obtained using single-shot fast spin echo sequences. CONCLUSIONS: The following conclusions are drawn: 1) Fetal motion is no longer a limitation for prenatal imaging after the implementation of parallel imaging with 2D FIESTA, 2) Cine MR imaging illustrates fetal motion in utero with high clinical reliability, 3) For cases involving major CNS anomalies, cine MR imaging provides information on extremity motility in fetuses and serves as a prognostic indicator of postnatal outcome, and 4) The cine MR used to observe fetal activity is technically 2D and conceptually three-dimensional. It provides four-dimensional information for making proper and timely obstetrical and/or postnatal management decisions.

Risk of psychiatric disorders following pelvic inflammatory disease: a nationwide population-based retrospective cohort study.

Pelvic inflammatory disease (PID) a common infection in women that is associated with significant morbidity and is a major cause of infertility. A clear temporal causal relationship between PID and psychiatric disorders has not been well established. We used a nationwide population-based retrospective cohort study to explore the relationship between PID and the subsequent development of psychiatric disorders. We identified subjects who were newly diagnosed with PID between 1 January 2000 and 31 December 2002 in the Taiwan National Health Insurance Research Database. A comparison cohort was constructed for patients without PID. A total of 21 930 PID and 21 930 matched control patients were observed until diagnosed with psychiatric disorders, or until death, withdrawal from the NHI system, or until 31 December 2009. Adjusted hazard ratio (HR) of bipolar disorder, depressive disorder, anxiety disorder and sleep disorder in subjects with PID were significantly higher (HR: 2.671, 2.173, 2.006 and 2.251, respectively) than that of the controls during the follow-up. PID may increase the risk of subsequent newly diagnosed bipolar disorder, depressive disorder, anxiety disorder and sleep disorder, which will impair life quality. Our findings highlight that clinicians should pay particular attention to psychiatric comorbidities in PID patients.

Risk of Psychiatric Disorders Following Symptomatic Menopausal Transition: A Nationwide Population-Based Retrospective Cohort Study.

Menopausal transition is highly symptomatic in at least 20% of women. A higher prevalence of psychiatric symptoms, including depression, anxiety, and sleep disturbance, has been shown in women with symptomatic menopausal transition. However, a clear correlation between symptomatic menopausal transition and psychiatric disorders has not been established.We explored the association between symptomatic menopausal transition and subsequent newly diagnosed psychiatric disorders, including schizophrenia as well as bipolar, depressive, anxiety, and sleep disorders.We investigated women who were diagnosed with symptomatic menopausal transition by an obstetrician-gynecologist according to the data in the Taiwan National Health Insurance Research Database. A comparison cohort comprised age-matched women without symptomatic menopausal transition. The incidence rate and the hazard ratios of subsequent newly diagnosed psychiatric disorders were evaluated in both cohorts, based on the diagnoses of psychiatrists.The symptomatic menopausal transition and control cohorts each consisted of 19,028 women. The incidences of bipolar disorders (hazard ratio [HR] = 1.69, 95% confidence interval [CI] = 1.01-2.80), depressive disorders (HR = 2.17, 95% CI = 1.93-2.45), anxiety disorders (HR = 2.11, 95% CI = 1.84-2.41), and sleep disorders (HR = 2.01, 95% CI = 1.73-2.34) were higher among the symptomatic menopausal transition women than in the comparison cohort. After stratifying for follow-up duration, the incidence of newly diagnosed bipolar disorders, depressive disorders, anxiety disorders, and sleep disorders following a diagnosis of symptomatic menopausal transition remained significantly increased in the longer follow-up groups (1-5 and ≥ 5 years).Symptomatic menopausal transition might increase the risk of subsequent newly onset bipolar disorders, depressive disorders, anxiety disorders, and sleep disorders. A prospective study is necessary to confirm these findings.

Risk of Psychiatric Disorders following Irritable Bowel Syndrome: A Nationwide Population-Based Cohort Study.

BACKGROUND: Irritable bowel syndrome (IBS) is the most common functional gastrointestinal (GI) disorder observed in patients who visit general practitioners for GI-related complaints. A high prevalence of psychiatric comorbidities, particularly anxiety and depressive disorders, has been reported in patients with IBS. However, a clear temporal relationship between IBS and psychiatric disorders has not been well established. OBJECTIVE: We explored the relationship between IBS and the subsequent development of psychiatric disorders including schizophrenia, bipolar disorder, depressive disorder, anxiety disorder, and sleep disorder. METHODS: We selected patients who were diagnosed with IBS caused by gastroenteritis, according to the data in the Taiwan National Health Insurance Research Database. A comparison cohort was formed of patients without IBS who were matched according to age and sex. The incidence rate and the hazard ratios (HRs) of subsequent new-onset psychiatric disorders were calculated for both cohorts, based on psychiatrist diagnoses. RESULTS: The IBS cohort consisted of 4689 patients, and the comparison cohort comprised 18756 matched control patients without IBS. The risks of depressive disorder (HR = 2.71, 95% confidence interval [CI] = 2.30-3.19), anxiety disorder (HR = 2.89, 95% CI = 2.42-3.46), sleep disorder (HR = 2.47, 95% CI = 2.02-3.02), and bipolar disorder (HR = 2.44, 95% CI = 1.34-4.46) were higher in the IBS cohort than in the comparison cohort. In addition, the incidence of newly diagnosed depressive disorder, anxiety disorder, and sleep disorder remained significantly increased in all of the stratified follow-up durations (0-1, 1-5, ≥5 y). CONCLUSIONS: IBS may increase the risk of subsequent depressive disorder, anxiety disorder, sleep disorder, and bipolar disorder. The risk ratios are highest for these disorders within 1 year of IBS diagnosis, but the risk remains statistically significant for more than 5 years. Clinicians should pay particular attention to psychiatric comorbidities in IBS patients.

Nuchal translucence incorporated into a one-stage multifactorial screening model for Down syndrome prediction at second-trimester pregnancy.

The aim of this study was to achieve one-stage screening for trisomy 21 using a combination of nuchal translucency (NuT) measurement and maternal serum alpha-fetoprotein (AFP) and free beta-human chorionic gonadotrophin (hCG) biochemistry levels in the second trimester among a high-risk study population. From January 1998 to June 2001, 45 cases of trisomy 21 were prenatally found and confirmed in the hospital-based cytogenetic diagnosis laboratory. A total of 867 normal singleton pregnancies were enrolled as controls from the antenatal care clinics in the hospital. All study and control subjects between 13 weeks and 18 weeks of gestation with a mean age of 15.2 +/- 1.3 weeks underwent one-stage nuchal translucence measurements and maternal serum biochemical screening for Down syndrome. The final logistic model contained beta-hCG (multiples of the gestational median or MoM), maternal age (matA), nuchal translucence (NuT MoM) and AFP (MoM) as covariates. Also, the estimated coefficients of the regression were highly significant. This model provided the estimated probability of Down syndrome as follows: Pr (Down syndrome) = exp (Z)/ [1 + exp (Z)], where Z = -11.18 + 0.64 x (beta-hCG MoM) + 0.25 x matA + 1.32 x NuT MoM -2.23 x AFP MoM. The logistic regression with estimated coefficients was installed in a Palm digital assistant (PDA) equipped with Excel (Microsoft). The risk probability of Down syndrome could be readily calculated after inputting data for all four predictor variables.

Leptin concentrations in the umbilical vein and artery. Relationship to maternal and neonatal anthropometry.

OBJECTIVE: To determine the relationships between serum leptin levels in the umbilical vein (UV) and artery (UA) and the anthropometry of mothers and neonates. STUDY DESIGN: Blood was taken from 61 pregnant women who were admitted for delivery and from the umbilical vein and artery just before delivery of the placenta. Leptin level was measured by immunoradiometric assay. Comparisons between serum leptin concentrations in UVs and both maternal and neonatal anthropometry were made according to neonatal sex. RESULTS: Mean leptin UA and UV concentrations in female infants were significantly higher than those in male infants (both, P = .002). Leptin concentrations in UVs of the total infants were related to maternal body weight and body mass index preconceptionally as well as at birth, to neonatal birth weight, to gestational age, to Kaup index and to body fat content of the infants. CONCLUSION: A sex difference was observed not only in serum leptin concentrations UA and UV but also in the degree of significance between the relationship of cord leptin and both maternal and neonatal anthropometry. Also, the UA leptin level had a closer relationship to neonatal anthropometry, but the UV leptin level was more closely related to maternal anthropometry.

Successful conservative treatment for advanced interstitial pregnancy. A case report.

BACKGROUND: Interstitial pregnancy is a relatively rare and life-threatening disease, occurring in 2-4% of all extrauterine pregnancies, and the maternal mortality rate is 2-2.5%. Laparoscopic surgery and, less commonly, methotrexate are the treatments of choice for interstitial pregnancy. However, there is another treatment, ultrasound-guided direct injection of etoposide, the effect and safety of which are unclear. CASE REPORT: In a 32-year-old woman with interstitial pregnancy at 12 weeks of gestation, ultrasound-guided direct injection of etoposide (100 mg) was used successfully after intravenous high-dose methotrexate, 300 mg (200 mg/m2), therapy failed to produce a response. The patient's posttherapeutic course was smooth. Twelve months after treatment, she conceived and later delivered a healthy infant vaginally without adverse events. CONCLUSION: Ultrasound-guided direct injection of etoposide offers another choice for treating advanced interstitial pregnancy, but further study is needed to define its efficacy and safety.
