Neonatal morbidity and care-seeking behaviour in rural Bangladesh.

The present study was undertaken to assess the pattern of reported neonatal morbidity and the care-seeking behaviour for neonates in rural Bangladesh. Data were collected from 1511 women who had live births during January 1996-August 1998 in four rural subdistricts, which are the field sites of the Operations Research Project of the International Centre for Diarrhoeal Disease Research, Bangladesh. A structured questionnaire was used to collect information from the mothers who were interviewed in their homes. Forty-nine per cent of the neonates were reported to have suffered from some kind of morbidity. Fever was the most common morbidity reported in the study population (21 per cent), followed by breathing difficulty (11 per cent). Birth order, complications during pregnancy, and/or delivery and death of a sibling were found to be significantly associated with reported neonatal morbidity. Eighty-seven per cent of the mothers sought care for their newborns. Some were taken to several different providers, the commonest being homeopaths (38 per cent) and village doctors (37 per cent). Seventeen per cent were taken to trained providers, and only 5 per cent to government health facilities. Seeking care from trained providers was found to be associated with the gender of the neonate, birth order, antenatal care of the mother from trained providers, father's education and monthly expenditure of the family. The results of this study suggest that efforts should be made to raise community awareness regarding neonatal morbidity, the importance of seeking care from trained personnel and the availability of services for these conditions.

Does the formulation of enteral feeding products influence infectious morbidity and mortality rates in the critically ill patients? A critical review of the evidence.

OBJECTIVE: To examine the relationship between the formulation of enteral nutrition and nosocomial infection in critical illness. DATA SOURCES: Computerized search of published research and reference list review. STUDY SELECTION: Review of 151 citations. Included are 31 primary studies in which the authors described the formulation of enteral nutrition and its effect on infectious morbidity and mortality rates in critically ill humans or animals. DATA EXTRACTION: Abstraction of the methods of primary studies and the impact of the composition of enteral nutrition on infectious morbidity and mortality rates. DATA SYNTHESIS: There is no evidence that the addition of branch-chain amino acids or nucleotides to enteral nutrition reduces infectious morbidity in animals or humans. Supplementation with fish oil, arginine, or glutamine has a variable impact on survival in animal models; there are no clinical trials in critically ill patients that demonstrate reduced infectious morbidity or mortality rates. Some animal studies suggest that intestinal overgrowth and bacterial translocation may be related to the type of fiber used, or elemental or polymeric formulas. Preliminary evidence suggests that Modular Tube Feeds (an enteral formula developed at the Shriner's Burn Institute, Cincinnati, OH), and a commercially available enteral formula (enhanced with omega-3-fatty acids, arginine, and yeast RNA; Impact, Sandoz Nutrition, Minneapolis, MN) may result in decreased infections in burn and postoperative cancer patients, respectively, but not in critically ill patients. Acidification of enteral feeding results in decreased bacterial colonization of the stomach in critically ill patients. CONCLUSIONS: Insufficient experimental data exist to permit conclusions that enteral nutrition formulations or supplements reduce infectious morbidity and mortality rates, but results are promising enough to warrant further research.

Perioperative determinants of morbidity and mortality in elderly patients undergoing cardiac surgery.

OBJECTIVE: To determine perioperative predictors of morbidity and mortality in patients > or =75 yrs of age after cardiac surgery. DESIGN: Inception cohort study. SETTING: A tertiary care, 54-bed cardiothoracic intensive care unit (ICU). PATIENTS: All patients aged > or =75 yrs admitted over a 30-month period for cardiac surgery. INTERVENTION: Collection of data on preoperative factors, operative factors, postoperative hemodynamics, and laboratory data obtained on admission and during the ICU stay. MEASUREMENTS AND MAIN RESULTS: Postoperative death, frequency rate of organ dysfunction, nosocomial infections, length of mechanical ventilation, and ICU stay were recorded. During the study period, 1,157 (14%) of 8,501 patients > or =75 yrs of age had a morbidity rate of 54% (625 of 1,157 patients) and a mortality rate of 8% (90 of 1,157 patients) after cardiac surgery. Predictors of postoperative morbidity included preoperative intraaortic balloon counterpulsation, preoperative serum bilirubin of >1.0 mg/dL, blood transfusion requirement of >10 units of red blood cells, cardiopulmonary bypass time of >120 mins (aortic cross-clamp time of >80 mins), return to operating room for surgical exploration, heart rate of >120 beats/min, requirement for inotropes and vasopressors after surgery and on admission to the ICU, and anemia beyond the second postoperative day. Predictors of postoperative mortality included preoperative cardiac shock, serum albumin of <4.0 g/dL, systemic oxygen delivery of <320 mL/ min/m2 before surgery, blood transfusion requirement of >10 units of red blood cells, cardiopulmonary bypass time of >140 mins (aortic cross-clamp time of >120 mins), subsequent return to the operating room for surgical exploration, mean arterial pressure of <60 mm Hg, heart rate of >120 beats/min, central venous pressure of >15 mm Hg, stroke volume index of <30 mL/min/m2, requirement for inotropes, arterial bicarbonate of <20 mmol/L, plasma glucose of >300 mg/dL after surgery, and anemia beyond the second postoperative day. During the study period, the study cohort used 6,859 (21.5%) ICU patient-days out of a total 31,867 ICU patient-days. Nonsurvivors used 2,023 (30%) ICU patient-days and patients with morbidity used 5,903 (86%) ICU patient-days. CONCLUSIONS: Severe underlying cardiac disease (including shock, requirement for mechanical circulatory support, hypoalbuminemia, and hepatic dysfunction), intraoperative blood loss, surgical reexploration, long ischemic times, immediate postoperative cardiovascular dysfunction, global ischemia and metabolic dysfunction, and anemia beyond the second postoperative day predicted poor outcome in the elderly after cardiac surgery. Postoperative morbidity and mortality disproportionately increased the utilization of intensive care resources in elderly patients. Future efforts should focus on preoperative selection criteria, improvement in surgical techniques, perioperative therapy to ameliorate splanchnic and global ischemia, and avoidance of anemia to improve the outcome in the elderly after cardiac surgery.

Prognostic significance of 24-h ambulatory blood pressure characteristics for cardiovascular morbidity in a population of elderly men.

OBJECTIVE: This study aimed to investigate the prognostic significance of 24-h ambulatory systolic (SBP), diastolic (DBP) and pulse pressure (PP), and blood pressure (BP) variability for cardiovascular morbidity in elderly men. DESIGN AND METHODS: Twenty-four hour ABP monitoring was performed in 70-year-old men (n = 872) participating in a longitudinal population-based study. The population was followed for up to 9.5 years, and the relationship between different blood pressure components and cardiovascular (CV) morbidity was assessed by Cox proportional hazard analysis. RESULTS: During follow-up, 172 CV events occurred (2.97 per 100 person-years). SBP and PP, both office and ambulatory, were significant predictors of CV morbidity. Twenty-four hour ambulatory PP [hazard ratio (HR) for 1 SD increase in BP 1.32, 95% confidence interval (CI) 1.15-1.52] and daytime ambulatory PP (HR 1.29, 95% CI 1.13-1.48) predicted CV morbidity independently of office PP and other established CV risk factors. Addition of night-time PP to a regression model with daytime PP and covariates did not increase the predictive value. However, the variability of daytime SBP (adjusted HR 1.24, 95% CI 1.07-1.42) provided additional prognostic power, independently of the 24-h SBP level. CONCLUSIONS: Ambulatory PP was a powerful predictor of CV morbidity in elderly men, independently of office PP and other established cardiovascular risk factors. Moreover, variability of daytime SBP added important prognostic information, suggesting that 24-h ambulatory BP monitoring may contribute to an improved risk assessment in elderly subjects.

The impact of the quantity of skeletal injury on mortality and pulmonary morbidity.

OBJECTIVE: To determine if the quantity of skeletal injuries (and the timing to fixation) increases the mortality or pulmonary morbidity in patients with and without chest injuries. DESIGN: Retrospective analysis of trauma registry. Statistical analysis with multiple logistic regression and chi(2) analysis. METHODS: Looking specifically at adult patients (> 16 years), skeletal injury was quantified by determining the presence or absence of a fracture in specific body regions (humeri, forearm, femur, tibia, spine, and pelvis) for a maximum of 10 skeletal injuries. The timing of fixation for fractures was categorized as < 24 hours, < 48 hours, < 72 hours, < 5 days, > 5 days, or no fixation. Chest injuries and pulmonary morbidity were based on the accepted list of complications reported in the literature. RESULTS: Three groups were analyzed according to the presence or absence of a chest or skeletal injury: those without skeletal injury (group NSI, n = 59), those without chest injuries (group NCI, n = 108), and those with both skeletal and chest injuries (group B, n = 59) Pulmonary Complications: When all patient groups (NCI, NSI, and B) were pooled, greater chest injury (p < 0.0008), greater skeletal injury (p < 0.02), and delayed fixation (p < 0.04) were associated with increased risk of developing a pulmonary complication. In the group of patients without a chest injury (NCI), this risk was associated with greater head injury (p < 0.005) and greater skeletal injury (p < 0.04), whereas in the group without a skeletal injury (NSI), only chest injury demonstrated significance (p < 0.05). When both skeletal and chest injuries were present, greater head injury (p < 0.03) and fixation time (p < 0.03) increased the risk of developing a pulmonary complication. Mortality: With all patients pooled (NCI, B, and NSI), head injury (p < 0.02), abdominal injury (p < 0.012), and fixation time (p < 0.01) were risk factors. In patients without a chest injury (NCI), none of the indexed variables were associated with mortality. In patients without a skeletal injury (NSI), greater head injury (p < 0.01), greater chest injury (p < 0.01), and greater abdominal injury (p < 0.04) were risk factors for mortality. When both chest and skeletal injuries were present (B), only head injury (p < 0.0003) was associated with mortality. The prevalence of mortality and pulmonary complications were compared between groups NCI, NSI, and B. Group NCI had fewer pulmonary complications (p < 0.004) than the other groups (difference not significant). When examining mortality, group NCI had less mortality than groups NSI and B. CONCLUSION: The combination of skeletal and chest injuries does not seem to amplify the pulmonary morbidity and mortality compared with chest injury alone. The quantity of the skeletal injury and the time to fixation of structures affecting mobilization seem to have an effect on pulmonary morbidity and mortality. Better scientific studies on the effects of skeletal injury and timing to fixation in relation to pulmonary morbidity and mortality are required.

Postoperative morbidity in cases of cervical conization followed by vaginal hysterectomy.

In an attempt to define a group of patients at risk for relatively increased morbidity who have had vaginal hysterectomy after conization, we retrospectively analyzed patients who had hysterectomy for cervical intraepithelial neoplasia. Patients who had hysterectomy within 24 hours of conization had an overall morbidity rate of 42% and are compared to a second group of patients who had hysterectomy six weeks or more after conization, with a morbidity rate of 24%. A third group of patients who had hysterectomy without conization had an overall morbidity of 19%. These data suggest that a period of less than 24 hours from conization to hysterectomy, particularly in large teaching hospitals, leads to relatively greater morbidity.

Psychiatric morbidity in patients with chronic whiplash-associated disorder.

STUDY DESIGN: Prospective cohort with age- and gender-matched controls. OBJECTIVES: To compare psychiatric morbidity between two groups: patients having chronic symptoms after a whiplash injury and patients who recovered completely. SUMMARY OF BACKGROUND DATA: Psychiatric morbidity may influence the outcome of somatic diseases, and it has been suggested that psychological factors are often involved in the development of chronic symptoms after whiplash injuries, but there is no study assessing psychiatric morbidity in whiplash-associated disorder (WAD) using the Structured Clinical Interview for DSM-IV. METHODS: We studied a consecutive sample of 278 patients with a whiplash injury. Eighty-five had persisting neck pain after 1 year, and 38 of these participated in this study. For each patient with chronic neck pain at the 1 year follow-up, a gender- and age-matched recovered patient was selected from the study cohort of 278 cases. Psychiatric morbidity was determined using the Structured Clinical Interview for DSM-IV (SCID). The interview was conducted at 1 year after the accident (360 days, SD 2 days). RESULTS: The chronic WAD group had a significantly (P < 0.05) greater number of diagnoses 22 (58%) according to Axis I (acquired psychiatric disorders) than 11 (29%) the patients who were free of symptoms. This was also the case for Axis I diagnoses that were reported to have occurred before the accident (13 [34%]vs. 3 [8%]; P < 0.01). The most common diagnosis was depression; indeed, the number of patients with a history of depression at the time of the accident was significantly higher in the group who developed chronic pain compared to the group who recovered (11 [29%]vs. 3 [8%]; P < 0.05). CONCLUSIONS: A history of psychiatric disease was more common in patients with chronic symptoms (chronic WAD). The dominating, retrospectively reported psychiatric diagnosis both before and after the accident was depression. Psychiatric morbidity may be a patient-related risk factor for chronic symptoms after a whiplash injury. The development of chronic symptoms after awhiplash injury seems to be associated with psychiatric vulnerability.

HIV-1-related morbidity in adults, Abidjan, Côte d'Ivoire: a nidus for bacterial diseases.

We studied mortality and morbidity in 270 HIV-1-infected adults (60% women, median age 31 years, mean baseline CD4 count 331/mm(3) ) observed in a follow-up that lasted a median 10 months in Côte d'Ivoire. Survival and probability of remaining free from any episode of morbidity at 12 months were 0.80 and 0.50, respectively. Baseline CD4 count <200/mm(3) was the only variable associated with global morbidity and mortality, with hazard ratios of 2.50 and 7.57, respectively. The most frequent causes of morbidity were severe bacterial infections (incidence rate: 26.1 per 100 person-years [py]), followed by oral candidiasis (22.3% py), unexplained weight loss over 10% of baseline body weight (13.3% py), tuberculosis (10.1% py), unexplained chronic diarrhea (9.7% py), and isosporiasis (5.1% py). Nontyphoid Salmonella accounted for 37% of isolated strains during severe bacterial infections, followed by Streptococcus pneumoniae (34%), Escherichia coli (15%), and Shigella species (7%). A significant part of bacterial morbidity occurred in patients with baseline CD4 count > or = 200/mm(3), in whom the incidence rate of bacterial diseases was 21.3% py and the probability of remaining free from any bacterial infection at 12 months was 0.80 (vs. 36.4% py and 0.71 in patients with baseline CD4 count <200/mm(3); p =.07).

Smoking and morbidity frequency in a working population.

As part of Shell's health surveillance program, morbidity frequency and severity by smoking status (current smoker, exsmoker, nonsmoker) were compared for the 3-year period 1985 through 1987. Morbidity data for this study were extracted from the morbidity section of the Shell Health Surveillance System, which included all illness and absence events in excess of 5 days. Statistically significant positive associations were seen between smoking habits and overall morbidity, diseases of the circulatory system, and diseases of the respiratory system for both male and female employees. In addition, a significantly increased association between smoking and both non-motor vehicle accidents and motor vehicle accidents among current smokers was noted. Current smokers had a greater than 60% higher frequency rate (P less than .05) for non-motor vehicle accidents than nonsmokers for both men and women. Male smokers also had a 75% increased (P less than .05) motor vehicle accident rate. These results suggest that it may be possible to reduce overall illness and injury morbidity through implementation of successful smoking cessation programs.

Morbidity and mortality related to anaesthesia outside the operating room.

PURPOSE OF REVIEW: The purpose of this review is to provide information related to morbidity and mortality associated with anaesthesia outside the operating room. RECENT FINDINGS: There is an increasing demand for anaesthesia at remote locations. Because of its specific characteristics, resulting from the location and the patient, morbidity and mortality rates of remote location anaesthesia could differ from conventional operating room anaesthesia. However, no studies are currently available. On the basis of morbidity and mortality data from conventional operating room anaesthesia, we reached some important conclusions with regard to the safety of anaesthesia outside the operating room. A well-equipped anaesthesia machine, standard monitoring (electrocardiogram, oxygen saturation and non-invasive blood pressure), trained personnel and adequate planning should be standard for all out of the operating room procedures. When all these are in place, the incidence of morbidity or mortality should be comparable to that of anaesthesia provided in the operating room. SUMMARY: There is certainly a need for studies concerning morbidity and mortality at remote location anaesthesia. Special care for the prevention of hypothermia should be given to those patients undergoing long-lasting diagnostic procedures, e.g. magnetic resonance imaging scans or cardiological investigations.

Diarrhea morbidity and mortality in Mexican children: impact of rotavirus disease.

AIM: To analyze changes in prevalence and seasonality of diarrhea morbidity and mortality and to evaluate the impact of rotavirus disease among Mexican children younger than 5 years old. METHODS: Diarrhea surveillance was performed from 1990 to 2002. Rotavirus testing was performed on stool specimens from 1996 to 2002. Data were obtained from different surveillance systems considering a nationwide representation in Mexico. Diarrhea morbidity and mortality rates were analyzed against time to determine trends or seasonal patterns. RESULTS: Improvement of surveillance for all diarrhea episodes denoted an initial morbidity increase from 1995 to 1999, followed by a decrease by 2002, without any seasonal pattern. However, from 1990 to 1995, morbidity for severe diarrhea decreased 63%. From 1996 to 2002, 62-68% of severe diarrhea episodes occurring during the fall-winter season (FWS) were rotavirus-positive compared with 6-12% in the spring-summer season (SSS). From 1990 to 2002, diarrhea mortality decreased 84%. Higher mortality rates for children younger than 1 year old coincided precisely during the FWS, annually. Both severe diarrhea episodes and diarrhea deaths denoted a changing seasonal pattern. In 1990-1991, 2 waves of increased diarrhea activity occurred. The increase in SSS was much more pronounced than that in FWS. From 1992 to 1995 for severe diarrhea and from 1993 to 2002 for diarrhea deaths, the SSS frequencies subsequently reduced, whereas the FWS peaks remained annually. CONCLUSIONS: A significant reduction in morbidity and mortality of severe diarrhea has occurred from 1990 and 2002 in Mexican children younger than 5 years old. This is a consequence of preventive programs initiated for cholera control since 1991, which had greater impact on SSS diarrhea and limited response for FWS diarrhea, when rotavirus is mainly present. Currently rotavirus diarrhea requires new prevention strategies and specific control measures, such as a specific national vaccine program.

Donor-site morbidity after free vascularized autogenous fibular transfer: subjective and quantitative analyses.

The purpose of this study was to determine the subjective and quantitative donor-site morbidity after removal of a free vascularized fibula flap for autoreconstruction. Ten patients and six age-matched, healthy control subjects were included in this study. The postoperative periods ranged from 6 to 87 months. Subjective donor-site morbidity was assessed with a patient questionnaire and the Enneking system. For quantification of donor-site morbidity, gait was evaluated during normal walking, walking under visual and cognitive constraints, and walking at a velocity higher than the preferred one. In general, the patient perception of donor-site morbidity was low. Complaints were frequently mentioned, however, including pain (60 percent), dysesthesia (50 percent), a feeling of ankle instability (30 percent), and inability to run (20 percent). Gait analyses revealed that patients walked at a lower preferred velocity, compared with control subjects. Furthermore, they demonstrated significant increases in the coefficients of variation of stride time during walking under visual and cognitive loads and during walking at a velocity higher than the preferred one, compared with normal walking. These increases were not observed for control subjects. These findings suggest that the reautomatization of gait is affected among patients. This study demonstrates that fibula harvesting is associated with low subjective morbidity but frequent complaints. Walking during complex tasks and at high velocities reveals that restoration of gait is not complete after partial fibulectomy.

Predictive indices of morbidity and mortality after liver resection.

OBJECTIVE: To determine if use of Model for End-Stage Liver Disease (MELD) scores to elective resections accurately predicts short-term morbidity or mortality. SUMMARY BACKGROUND DATA: MELD scores have been validated in the setting of end-stage liver disease for patients awaiting transplantation or undergoing transvenous intrahepatic portosystemic shunt procedures. Its use in predicting outcomes after elective hepatic resection has not been evaluated. METHODS: Records of 587 patients who underwent elective hepatic resection and were included in the National Surgical Quality Improvement Program Database were reviewed. MELD score, CTP score, Charlson Index of Comorbidity, American Society of Anesthesiology classification, and age were evaluated for their ability to predict short-term morbidity and mortality. Morbidity was defined as the development of one or more of the following complications: pulmonary edema or embolism, myocardial infarction, stroke, renal failure or insufficiency, pneumonia, deep venous thrombosis, bleeding, deep wound infection, reoperation, or hyperbilirubinemia. The analysis was repeated with patients divided according to their procedure and their primary diagnosis. Parametric or nonparametric analyses were performed as appropriate. Also, a new index was developed by dividing the patients into a development and a validation cohort, to predict morbidity and mortality in patients undergoing elective hepatic resection. ROC curves were also constructed for each of the primary indices. RESULTS: CTP and ASA scores were superior in predicting outcome. Also, patients undergoing resection of primary malignancies had a higher rate of mortality but no difference in morbidity. CONCLUSION: MELD scores should not be used to predict outcomes in the setting of elective hepatic resection.

Morbidity following dental treatment of children under intubation general anaesthesia in a day-stay unit.

OBJECTIVES: To determine which variables were best related to the overall morbidity of a child undergoing dental general anaesthetic (GA) and then to use these variables to determine those factors that might influence the extent and severity of morbidity experienced by healthy children following dental GA. SAMPLE AND METHODS: Data were collected on anxiety, pain and morbidity, GA procedure and dental procedure from 121 children attending a day stay GA unit for dental treatment. Patients were interviewed preoperatively, postoperatively before discharge then four further times over the next 148 h. Data were analysed using multivariate regression. RESULTS: Thirty-one per cent of subjects had restorative work, 60% had at least one tooth extracted, 54% had a surgical procedure. Use of local analgesia reduced postoperative pain whilst an increase in the number of surgical procedures increased it. Increase in anaesthetic time was related to increased odds of feeling sleepy and nauseous, females were more likely to complain of sleepiness or weakness. Feelings of dizziness were increased if the patient was given local analgesia during the procedure. CONCLUSIONS: Pain following dental GA was the most prevalent and long lasting symptom of postoperative morbidity in this study. Reductions in operating time and improvement in pain control have the potential to reduce reported morbidity following dental GA.

Living or deceased donor kidney transplants for candidates with significant extrarenal morbidity.

BACKGROUND: Individuals with end-stage renal disease (ESRD) must weigh the benefits and risks of dialysis vs. a transplant. However, if the patient has extrarenal morbidity, survival may be limited. We have recommended that, when possible, recipients have a living donor (LD) transplant. However, it could be argued that for recipients with extrarenal morbidity, the potential benefit does not justify the donor risks and that, therefore, recipients with increased risks should be denied an LD transplant. MATERIALS AND METHODS: We studied the outcome of LD vs. deceased donor (DD) transplants in recipients with extrarenal morbidity. For recipients with extrarenal morbidity, patient survival (p < 0.01) and graft survival (p < 0.01) rates were significantly better for LD (vs. DD) transplant recipients. We found no difference in death-censored graft survival rates. CONCLUSION: Kidney transplant recipients with extrarenal morbidity benefit from an LD transplant. Both donor and recipient informed consent is important.

Effect of treating lower urinary tract symptoms on anxiety, depression and psychiatric morbidity: a one-year study.

BACKGROUND: The present study aimed to evaluate the effects of treating lower urinary tract symptoms (LUTS) on anxiety, depression and psychiatric morbidity following one year of follow-up. METHODS: A total of 297 patients were involved in this study. Patients were recruited into a surgical group (patients underwent transurethral resection of the prostate, n = 111), a medical group (underwent alpha-blockers treatment, n = 116) and a control group (renal stones patients with no or mild symptoms of severity, n = 70). Patients were assessed on anxiety, depression and psychiatric morbidity levels before and after treatment and were followed at 3, 6 and 12 months. RESULTS: The study showed that before treatment for LUTS, most of the patients, especially the surgical group compared to the medical and control groups, were more anxious, depressed and psychiatrically morbid. However, after treatment, most of the patients in the surgical group experienced a great improvement in their anxiety, depression and psychiatric morbidity level when compared to the medical and control groups. The reduction or improvement of their psychological profile was due to the reduction or total withdrawal of LUTS after treatment. CONCLUSION: Both medical and surgical treatment improved patient LUTS and thus improved their overall anxiety, depression and psychiatric morbidity.

Fetal fibronectin, endotoxin, bacterial vaginosis and cervical length as predictors of preterm birth and neonatal morbidity in twin pregnancies.

OBJECTIVE: To evaluate the predictive values of fetal fibronectin, bacterial vaginosis, endotoxin and cervical length for preterm birth (< 35 and < 37 weeks) and neonatal morbidity in twin pregnancies. PARTICIPANTS: One-hundred and twenty-one women with twin pregnancies recruited into a prospective longitudinal study at three antenatal clinics in the southwest of Sweden. METHODS: Cervical or vaginal fluid was sampled and determined for fetal fibronectin (> or = 0.05 microgram/mL was used as cutoff), endotoxin (> or = 100 pg/mL) and bacterial vaginosis (presence of clue cells) at two week intervals from 24 to 34 weeks of gestation. The cervical length was measured with transvaginal sonography at the same time intervals. MAIN OUTCOME MEASURES: Occurrence of preterm birth (< 35 and < 37 weeks of gestation) and neonatal morbidity. RESULTS: All positive fetal fibronectin samples obtained at screening between 24 and 34 weeks predicted birth < 35 weeks (RR 18.0; 95% CI 2.2-145.9). A positive fetal fibronectin at 28 weeks of gestation predicted delivery < 35 weeks (RR 6.3; 95% CI 2.6-15.1) with a sensitivity, specificity, positive and negative predictive value of 50.0, 92.0, 62.5 and 87.3%, respectively. An independent association between fetal fibronectin at 28 weeks and preterm birth (< 35 weeks) was verified with logistic regression (P = 0.03). A positive fetal fibronectin at 28 weeks of gestation predicted neonatal morbidity (RR 5.1; 95% CI 2.4-11.0) and a longer period of care at the neonatal intensive care unit. The predictive power of cervical sonography was generally low but cervical length (cutoff < or = 33 mm) measured at 28 weeks of gestation was significantly associated with birth < 37 weeks (RR 2.2; 95% CI 1.1-4.2). The presence of endotoxin correlated to bacterial vaginosis, but these tests were not significantly related to preterm birth or neonatal morbidity. CONCLUSIONS: Fetal fibronectin predicted preterm birth and neonatal morbidity in twin pregnancies. The predictive value of cervical length determinations was low. Endotoxin and bacterial vaginosis had no predictive power for preterm delivery in this study.

Maternal and neonatal morbidity after first vaginal delivery using Thierry's spatulas.

OBJECTIVE: To analyse maternal and neonatal morbidity associated with instrumental delivery using Thierry's spatulas. METHODS: Between January 2001 and December 2003, 570 nulliparous women with term, singleton, cephalic pregnancies gave birth by either instrumental (n = 279) or spontaneous vaginal delivery (n = 291) and were studied in a retrospective case-control study. Maternal and neonatal morbidity were compared in the instrumental vs. spontaneous delivery groups. RESULTS: Women who underwent instrumental delivery using Thierry's spatula were more likely to have severe perineal tears (ORa 7.5, 95% CI 1.5, 32.3), urinary retention (OR 2.7, 95% CI 1.3, 5.6), postpartum blood loss (ORa 3.4, 2.4, 4.9) and extended hospital stay (OR 3.21, 95% CI 2.3, 4.6) than women having a spontaneous vaginal birth. Regarding the infant, one case of subgaleal haematoma was noted. No significant difference was noted in neonatal period. CONCLUSION: This data support the safety of Thierry's spatula on infant outcome. Maternal morbidity observed with Thierry spatulas was similar to that reported in the literature for other modes of instrumental delivery but the risk for perineal morbidity was higher than for spontaneous delivery. Neonatal morbidity appeared to be limited.
