Therapy side-effects and predictive factors for preterm delivery in patients undergoing tocolysis with atosiban or ritodrine for threatened preterm labour.

The objective of this study was to compare the safety and efficacy of atosiban and ritodrine in the treatment of threatened preterm labour (TPL) and to analyse the predictive factors of preterm delivery. We retrospectively sampled data on 380 women hospitalised for TPL (24-35 weeks' gestation), in our clinic between 2004 and 2007. All were subjected to tocolysis with ritodrine and/or atosiban. Data were analysed using R (version 2.12.1), considering p < 0.05 as significant. We had 69 women treated with atosiban, 242 treated with ritodrine and 69 treated with ritodrine changed for atosiban, if adverse effects occurred. In the multivariate logistic regression, the use of atosiban vs ritodrine does not play any role in delaying delivery after 48 h or 7 days, whereas the cervical change at the digital examination, high contractions pre/post-therapy ratio, pPROM, cervical length and fibronectin result as predictive factors for both delivery before 48 h or 7 days. Maternal adverse drug effects were significantly more frequent in patients treated with ritodrine, and one single case of pulmonary oedema was observed. We found fewer side-effects in the atosiban than in the ritodrine group and no difference in efficacy. Moreover, the most predictive factors for preterm delivery were fibronectin test, pPROM, digital vaginal examination and uterine contraction persistence. We believe that predictive capacity of these tests could give the opportunity for targeting therapy and limiting drug side-effects and cost.

[Intrahepatic cholestasis of pregnancy: diagnosis and obstetric management]. / Colestasi intraepatica della gravidanza: diagnosi e management ostetrico.

AIM: The aim of this study was to suggest a possible obstetric management of patients with intrahepatic cholestasis of pregnancy (ICP). METHODS: We performed a retrospective analysis enrolling 44 women with ICP deliveries at our Obstetrics and Gynaecology clinic of the University of Udine between January 2005 and July 2008. Data on patient age, body mass index, weight, gestational age, parity, symptoms, comorbidity, value of liver test, APGAR score and fetal weight were prospectively recorded in a computed database and clinical folder. RESULTS: The intensification of maternal and fetal surveillance in patients with ICP (liver function tests, ultrasound and cardiotocography), can significantly reduce perinatal mortality (no case of stillbirth in ours study) but, inevitably, increases the cesarean delivery rate (65.1%), the induction of labor rate (38.4%) and the preterm delivery rate (58.13 %, median gestational age 35 sg+/-1.46). CONCLUSION: Obstetric management of ICP consist of weighing the risk of premature delivery against the risk of sudden death in utero. To date, no ideal method of fetal surveillance has been determined for ICP; the intrauterine deaths are thought to occur suddenly and fetal cardiac monitoring cannot forecast an acute event. Nevertheless, we think that a management strategy, inclusive of induction of labor at 37 weeks, can reduces the risk of fetal death. In most severe cases, no responsive to ursodeoxycholic acid and S-adenosylmethionine treatment, delivery has been initiated even before the 37 weeks, as soon as lung maturity has been established.

Prepregnancy body mass index and adverse pregnancy outcomes.

OBJECTIVE: The aim of this study was to evaluate the association between prepregnancy BMI, and adverse maternal and neonatal outcomes. METHOD: In this retrospective cohort study 916 consecutive singleton gestations were included who gave birth between 1 January 2006 and 31 August 2006 at the Department of Obstetrics and Gynecology, University of Udine, Italy. Statistical analysis was performed using univaried logistic regression and measured by odds ratio. RESULTS: The obese patients had a statistically, significantly increased incidence of Caesarean section (OR = 2.17, p = 0.009). Women with overweight (OR = 2.43, p = 0.002) and obese weight (OR = 4.86, p < 0.0001) were at increased risk for preterm deliveries. The pre-eclampsia and the fetal macrosomia (> or =4,000 g) were increased in obese women (OR = 5.68, p < 0.0001; OR = 2.58, p = 0.033, respectively). CONCLUSION: Maternal prepregnancy obesity is significantly associated with increased risk of Caesarean section, preterm delivery, pre-eclampsia and macrosomia.

Varicose symptoms without varicose veins: the hypotonic phlebopathy, epidemiology and pathophysiology. The Acireale project.

Ever since 1982 the authors have been interested in varicose symptoms without varicose veins. Carrying out several pilot studies with infrared photoplethysmography (PPG) and strain gauge plethysmography they suggest that the pathophysiology of this behaviour could be caused by the reduction of the venous wall tone. They propose the name of Hypotonic Phlebopathy (HP). The diagnosis criteria are focused by symptoms (heavy legs in upright position, restless leg syndrome, sub-oedema and/or evening oedema) and signs detected by PPG, s.g plethysmography and duplex scanning (reduction of the muscle-venous calf pump and increase of the venous wall compliance). Epidemiology, assessed between 1989 and 1992 (Acireale Project), showed a 15.90% morbidity, with higher prevalence in females; the most important risk factors are pregnancy and family history. HP is not rare in males; the principal risk factor is work involving standing for long periods. These behaviours have been independently confirmed by two studies carried out in France in 1992, which showed a 15% prevalence in a similar group of subjects with functional venous insufficiency. The authors suggest the introduction of the term of Hypotonic Phlebopathy, the symptoms of which are significantly improved by phlebotonic drugs, especially when they are stronger.

Three-month therapy with calcium-heparin in comparison with ticlopidine in patients with peripheral arterial occlusive disease at Leriche-Fontaine IIb class.

Forty patients with a mean age of 62.6 +/- 6 years, 36 men and 4 women, with peripheral arterial occlusive disease (PAOD) at Leriche-Fontaine IIb class, were randomly allocated to one of two treatment groups, receiving either 12,500 IU/day of subcutaneous (sc) calcium-heparin (CAE) or 250 mg/day of oral ticlopidine, each given for ninety days. The following parameters were evaluated before the start of the active treatment period and after thirty and ninety days of treatment: pain-free walking distance (PWD), maximum walking distance (WDmax), systolic and diastolic blood pressure (BP), posterior tibial arterial pressure and Winsor index at rest and after exercise (treadmill), transcutaneous oxygen and carbon dioxide pressures at rest (TcPO2 and TcPCO2 respectively), and time to 50% TcPO2 recovery after three-minute ischemia. Both treatments induced an improvement in PWD/WDmax, which, at the end of the study, were increased by 50.7/58.7% and 31.7/36.2%, respectively, for CAE and ticlopidine treatments, respectively.

False positive 131I total body scan due to an ectasia of the common carotidis.

A cervical accumulation of radioiodine at Total Body Scan (TBS) in a patient who had been thyroidectomized for a follicular thyroid carcinoma led to unnecessary radioiodine treatment. Thyroglobulin measurements indicated constantly low levels. Following ultrasound scanning of the neck, echo-doppler examination of the cervical vessels and angiography with 99Tc, this area of increased activity at TBS imaging was shown to be due to an ectasia of the right common carotidis causing blood stasis and reverse flow.

Cholelithiasis and urolithiasis in ileostomy patients.

Terminal ileostomy is at present less frequently performed in favour of the use of surgical techniques which allow for the maintenance of continence. The problem of long-term metabolic complications is still open, though it has been stated that 1 year postoperatively, the life expectancy of ileostomy patients is similar to that of the general population. The series here reported consists of 13 patients only, however the increased risk of cholelithiasis and urolithiasis in ileostomy patients can be confirmed (15.4% in this study). These complications should be carefully examined in the follow-up of patients: while cholelithiasis cannot be prevented, for early diagnosis liver scanning every 24-36 months is advisable. As for urolithiasis, the patients should be encouraged to drink large amounts of water daily. Water does not cause an increase in ileostomy output while allowing a satisfactory renal flow. For early diagnosis direct abdominal X-ray with renal tomography every 24-36 months is suggested. In case of suspected kidney or ureteral stones, perfusion urography should be performed.

Effects of mesoglycan sulfate on the arterial elastic module.

Ten patients with peripheral obstructive arterial disease (POAD) in stages I and II according to Leriche-Fontaine, were subjected to therapy with mesoglycan sulfate (60 mg/day for twenty days), to evaluate the effect of the drug on the elastic module of the arterial wall. The wall elasticity was deduced from some Doppler velocitographic indices (arterial dynamics index, resistance index, perfusion pressure index, tibial distensibility index); from the analysis of systolic, protodiastolic, and end diastolic velocity variations; and from computerized analysis of the Doppler sound spectrum. The results show a significant improvement of arterial wall elasticity, which suggests a rational use for the drug in the initial stages of peripheral obstructive arterial disease.

Burn and stricture of the ostomy due to colostomy irrigation. Report of a case.

A case of burn and stricture of the ostomy subsequent to colostomy irrigation is reported. Heretofore, perforation has been the only serious complication noted. In this case, it was necessary to reconstruct the ostomy because of the development of postburn stricture.
