admission. This proportion could already be greater in some parts of the country and may increase if referrals of cases of self-poisoning increase faster than the facilities for their assessment and management. The provision of social work and psychiatric expertise in casualty departments may be one means of preventing unnecessary medical admissions without risk to the patients. Dr Blake's and Dr Bramble's figures do not demonstrate, however, that any advantage would attach to medical teams taking over assessment from psychiatrists except that, by implication, assessments would be completed sooner by staff working on the ward full time. What the figures actually suggest is that if assessment of overdoses were left to house doctors there would be an increase in admissions to psychiatric units (by 19°U), outpatients (by 5O°'), and referrals to social services (by 140o). So for house doctors to assess overdoses would provide no economy for the psychiatric or social services. The study does not tell us what the consequences would have been for the six patients who the psychiatrists would have admitted but to whom the house doctors would have offered outpatient appointments.

ACOG practice bulletin: Clinical management guidelines for obstetrician-gynecologists

Pre-eclampsia is a common disorder that particularly affects first pregnancies. The clinical presentation is highly variable but hypertension and proteinuria are usually seen. These systemic signs arise from soluble factors released from the placenta as a result of a response to stress of syncytiotrophoblast. There are two sub-types: early and late onset pre-eclampsia, with others almost certainly yet to be identified. Early onset pre-eclampsia arises owing to defective placentation, whilst late onset pre-eclampsia may center around interactions between normal senescence of the placenta and a maternal genetic predisposition to cardiovascular and metabolic disease. The causes, placental and maternal, vary among individuals. Recent research has focused on placental-uterine interactions in early pregnancy. The aim now is to translate these findings into new ways to predict, prevent, and treat pre-eclampsia.

Pre-eclampsia: pathophysiology and clinical implications

Pregnancy in Adolescence: Is It an Obstetrical Risk?

Neutrophil-to-lymphocyte ratio as a diagnostic marker of intrahepatic cholestasis of pregnancy.

INTRODUCTION Preeclampsia is a serious disease which may result in maternal and neonatal mortality and morbidity. Improving the outcome for preeclampsia necessitates early prediction of the disease to identify women at high risk. Measuring blood cell subtype ratios, such as the neutrophil to lymphocyte (NLR) and platelet to lymphocyte (PLR) ratios, might provide prognostic and diagnostic clues to diseases. AIM To investigate hematological changes in early pregnancy, using simple complete blood count (CBC) and blood concentrations of beta-human chorionic gonadotropin (β-hCG) and pregnancy-associated plasma protein-A (PAPP-A) to determine whether these measures are of any value in the prediction and early diagnosis of preeclampsia. MATERIALS AND METHODS Six hundred fourteen consecutive pregnant women with preeclampsia (288 with mild disease and 326 with severe disease) and 320 uncomplicated pregnant women were included in the study. Blood samples for routine CBC and first trimester screen, which combines PAPP-A and free β-hCG blood concentrations, were analyzed. RESULTS The NLR values were significantly higher in the severe preeclampsia group compared with the control group (p<0.001). We also confirmed that levels of PAPP-A were lower in patients who developed preeclampsia. CONCLUSION Because measuring CBC parameters, particularly NLR, is fast and easily applicable, they may be used to predict preeclampsia.

Objective To evaluate the use of the Bakri balloon in postpartum hemorrhage (PPH) resistant to medical treatment. Methods The Bakri balloon was applied to 45 women with PPH after failure of initial management. Bilateral internal iliac artery ligation (BIIAL) and hysterectomy were performed if necessary. Results The Bakri balloon was applied in 45 women; an additional BIIAL was required in nine women. The mean inflation volume of the Bakri balloon was 571±264 mL (range: 240-1300 mL). Hemostasis was achieved in 34 (75.5%) women with the Bakri balloon alone, and in six women with an additional BIIAL. The Bakri balloon was effective with additional procedures overall in 40 of 45 (88.8%) women. In 34 women with uterine atony, the Bakri balloon was successful alone in 27 (79.4%) and with an additional BIIAL in 30 (88.2%) women. An inflation volume of >500 mL was necessary in 18 women with uterine atony. Conclusion The Bakri balloon may be performed as a first line of treatment for PPH resistant to uterotonic agents, and can be used not only in tertiary centers but also in limited-resource centers. The inflation volume of the Bakri balloon should be adjusted according to the type of PPH; a volume exceeding 500 mL may be necessary in uterine atony.

Balloon tamponade for the management of postpartum uterine hemorrhage

Aim

Intrahepatic cholestasis of pregnancy (ICP), the most common liver disease in pregnancy, is characterized by elevated serum total bile acid and/or transaminase concentration, and pruritus. Interleukin-6 (IL-6) is a key regulator of the immune response, hematopoiesis and inflammation. We examined both IL-6 and the frequently used inflammatory marker high-sensitivity C-reactive protein (hs-CRP) at baseline in the same study population as for the primary endpoint, in order to provide a new perspective on the pathogenesis of ICP.



Methods

In this controlled cross-sectional study 65 consecutive pregnant women with ICP (34 with mild and 31 with severe disease) and 40 healthy women with uncomplicated pregnancies (control group) were examined. IL-6 and hs-CRP were compared between the groups.



Results

While serum IL-6 was significantly higher in the mild ICP (P = 0.01) and severe ICP (P = 0.001) groups than in the control group, hs-CRP was similar between the groups.



Conclusion

Interleukin-6 may have an essential role, apart from CRP, in the pathogenesis of ICP and, also, is a more sensitive marker of inflammation.
