Vein Patch Closure Using Below the Knee Greater Saphenous Vein for Femoral Endarterectomy Procedures is Not Always a Safe Choice

Background

The complication of vein patch rupture is well described after carotid patch angioplasty; however, there is a paucity of data about the safety of vein patch closure in the setting of femoral endarterectomy.

Methods/results

From May 2012 to May 2015, 115 femoral endarterectomies with patch closure were performed. A patch rupture occurred in three cases (2.6%) with a mortality rate of 66% (2/3). In all cases the greater saphenous vein below the knee was used as patch material.

Discussion/conclusion

Vein patches, particularly from small calibre veins, should be excluded in femoral endarterectomy procedures as they pose a substantial risk of rupture.

•

Choice of patch material for endarterectomy procedures of the common femoral artery may be crucial.

•

Patch rupture after use of the greater saphenous vein occurs in 3% of cases.

•

A particular risk of rupture occurs after the use of below knee greater saphenous vein patches.

•

Patch rupture is associated with a high mortality rate.

[Sexual dysfunction associated with psychotropic drugs and treatment options]

BACKGROUND

Sexual dysfunction associated with psychotropic drugs is a threat to patient quality of life and a major reason for non-compliance. Psychotropic agents can impair the sexual response in different ways due to their neurobiological mode of action.

OBJECTIVE

Presentation of the frequencies of sexual functional disorders for selected psychopharmacological groups and the available treatment modalities.

METHODS

Literature search, selection and review of relevant studies.

RESULTS

The most relevant groups for impairments are antidepressants and antipsychotics due to the serotonin agonistic and anti-dopaminergic properties as well as the prolactin increasing characteristics. Agents with a favorable side effects profile are now available. All phases of the sexual response are affected.

DISCUSSION

The treatment of psychiatric disorders should follow a comprehensive treatment plan that anticipates a likely sexual dysfunction at the initiation of treatment. The main aim is improvement of the underlying primary disorder. Some limited evidence-based treatment strategies are available.

Cluster-randomized controlled trial of dissemination strategies of an online quality improvement programme for alcohol-related disorders

AIMS

This project investigated different dissemination strategies of an online quality improvement programme for alcohol-related disorders into routine care in South Baden and South Württemberg in Germany.

METHODS

In a cluster-randomized controlled trial, 112 general practices were randomized into three groups. The first group (n = 43) received access to the online system and a training programme for the general practitioners (GPs). The second group (n = 42) additionally received education for the whole practice team. The third group (n = 27) acted as control and received only access to the online system.

RESULTS

Two thousand six hundred and forty-seven practitioners were asked to take part in the study, and it was possible to randomize 112 (4%) practices. There were no significant differences concerning the use of the system between the groups: 41.9% of the GPs in the first group, 42.9% in the second group and 44.4% in the control group used the system. In terms of only the system users, 55.6% of the GPs in the first group, 33.3% in the second group and 8.3% in the control group used the system six times or more (P = 0.019). Diagnostic assessments made by the GPs in the groups differed substantially: 72.2% of diagnoses in the first group were correct, while this figure lay at 69.7% in the second group and 36.4% in the control group (P = 0.034).

CONCLUSIONS

No effect of the additional training on the primary outcome (acceptance) was identified, but on two of the secondary outcomes. Further cost-effectiveness studies should investigate whether the effort involved in providing training additionally to the system is justifiable. The study is registered at ClinicalTrials.gov: NCT00314067. This article conforms to the guidelines in the Consolidated Standards of Reporting Trials (CONSORT) statement (Moher et al., 2001; Campbell et al., 2004).

Finding the ideal place for a psychotherapeutic intervention in a stepped care approach--a brief overview of the literature and preliminary results from the Project PREDICT

AIMS

To provide an overview over empirical evidence regarding stepped care approaches that include psychotherapies. To present own preliminary study results in alcohol dependent patients.

METHODS

Publications were searched in the databases Medline, PsycINFO and the internet search engine Google Scholar. Inclusion criteria were psychosocial treatment and psychiatric disorders. Our own study consists of two steps. In step 1 patients receive anti-craving medication or placebo and Medical Management (MM). After a relapse to heavy drinking patients can step up and after randomization they either continue with the same treatment or they receive additional alcoholism specific psychotherapy (ASP).

RESULTS

Evidence suggests that stepped care might be efficacious in patients with obsessive-compulsive behavior and depression. There is no evidence for efficacy in problem drinkers. Results of our own study show that the completer rate in MM alone is higher than in ASP with MM, but there are no significant differences concerning age, sex and disease severity between completer and non-completer in both study arms.

CONCLUSIONS

Further research with regard to stepped care in alcohol dependent patients is needed. An introduction of the psychotherapy at earlier stages might be sensible.

St John's wort for depression

BACKGROUND

Extracts of the plant Hypericum perforatum L. (popularly called St. John's wort) have been used in folk medicine for a long time for a range of indications including depressive disorders.

OBJECTIVES

To investigate whether extracts of hypericum are more effective than placebo and as effective as standard antidepressants in the treatment of depressive disorders in adults; and whether they have have less adverse effects than standard antidepressant drugs.

SEARCH STRATEGY

Trials were searched in computerized databases (Cochrane Collaboration Depression, Anxiety & Neurosis Group Clinical Trials Registers; PubMed); by checking bibliographies of pertinent articles; and by contacting manufacturers and researchers.

SELECTION CRITERIA

Trials were included if they: (1) were randomized and double-blind; (2) included patients with depressive disorders; (3) compared extracts of St. John's wort with placebo or standard antidepressants; and (4) included clinical outcomes such as scales assessing depressive symptoms.

DATA COLLECTION AND ANALYSIS

Information on patients, interventions, outcomes and results was extracted by at least two independent reviewers using a standard form. The main outcome measure for comparing the effectiveness of hypericum with placebo and standard antidepressants was the responder rate ratio (responder rate in treatment group/responder rate in control group). The main outcome measure for adverse effects was the number of patients dropping out for adverse effects.

MAIN RESULTS

A total of 37 trials, including 26 comparisons with placebo and 14 comparisons with synthetic standard antidepressants, met the inclusion criteria. Results of placebo-controlled trials showed marked heterogeneity. In trials restricted to patients with major depression, the combined response rate ratio (RR) for hypericum extracts compared with placebo from six larger trials was 1.15 (95% confidence interval (CI), 1.02-1.29) and from six smaller trials was 2.06 (95% CI, 1.65 to 2.59). In trials not restricted to patients with major depression, the RR from six larger trials was 1.71 (95% CI, 1.40-2.09) and from five smaller trials was 6.13 (95% CI, 3.63 to 10.38). Trials comparing hypericum extracts and standard antidepressants were statistically homogeneous. Compared with selective serotonin reuptake inhibitors (SSRIs) and tri- or tetracyclic antidepressants, respectively, RRs were 0.98 (95% CI, 0.85-1.12; six trials) and 1.03 (95% CI, 0.93-1.14; seven trials). Patients given hypericum extracts dropped out of trials due to adverse effects less frequently than those given older antidepressants (Odds ratio (OR) 0.25; 95% CI, 0.14-0.45); such comparisons were in the same direction, but not statistically significantly different, between hypericum extracts and SSRIs (OR 0.60, 95% CI, 0.31-1.15).

AUTHORS' CONCLUSIONS

Current evidence regarding hypericum extracts is inconsistent and confusing. In patients who meet criteria for major depression, several recent placebo-controlled trials suggest that the tested hypericum extracts have minimal beneficial effects while other trials suggest that hypericum and standard antidepressants have similar beneficial effects. As the preparations available on the market might vary considerably in their pharmaceutical quality, the results of this review apply only to the products tested in the included studies.

Long term inhalation of iloprost in a child with primary pulmonary hypertension: an alternative to continuous infusion

Primary pulmonary hypertension is a rare disease in childhood associated with a poor prognosis. However, during the past 10 years, pulmonary vasodilator treatment has somewhat improved its prognosis. Long term continuous infusion of prostacyclin (epoprostenol) has been shown to improve physical capacity and to reduce mortality in primary and secondary pulmonary hypertension. It has been reported in adults that daily repetitive inhalation of iloprost, a prostacyclin analogue, seems also suitable for long term therapy of pulmonary hypertension. Repetitive inhalation of iloprost was administered to a 5 year old boy with severe primary pulmonary hypertension. He showed continuous clinical improvement without any side effects over the three years of treatment. This treatment may offer an alternative to continuous intravenous prostacyclin infusion and obviates the need for a permanent central venous catheter.

Choosing a strategy to prevent neonatal early-onset group B streptococcal sepsis: economic evaluation

OBJECTIVE

To determine the most appropriate strategy to prevent neonatal streptococcal sepsis in a setting with a low incidence of the disease.

DESIGN

Decision analysis and economic evaluation.

SETTING

Geneva University Hospitals, Switzerland.

POPULATION

Pregnant women at 35-37 weeks of gestation and in labour.

METHODS

Local data and data from the literature were used in a decision analysis to compare the current policy of antibiotic administration at Geneva University Hospitals with the recommended preventive strategies.

MAIN OUTCOME MEASURES

Number of episodes of sepsis averted; cost and number needed to treat to prevent one episode of sepsis; and proportion of women receiving antibiotics during labour.

RESULTS

Compared with the current policy, the risk factors strategy would prevent 69 streptococcal sepsis per million deliveries and the screening strategy would prevent 102 cases of sepsis per million deliveries. Cost per averted sepsis case would be 60 pounds, 700 and 473 pounds, 600, respectively. The number needed to treat to prevent one sepsis would be 1,087 with a risk factors strategy and 1,029 with a screening strategy. Preventive strategies would increase the proportion of women receiving antibiotics during labour from 6% with the current policy, to 13.5% and 16.5% respectively.

CONCLUSIONS

Preventive strategies are more effective than the current policy, but imply increased hospital costs and a notable increase in the proportion of women receiving antibiotics during labour, which may be unjustified in a low incidence setting.

Inhaled nitric oxide versus aerosolized iloprost in secondary pulmonary hypertension in children with congenital heart disease: vasodilator capacity and cellular mechanisms

BACKGROUND

Inhaled nitric oxide (iNO) has been used to assess the vasodilator capacity of the pulmonary vascular bed in children with congenital heart disease and elevated pulmonary vascular resistance. Inhaled iloprost is a pulmonary vasodilator for the long-term treatment of pulmonary hypertension (PHT). Because these 2 vasodilators act through different pathways (release of cGMP or cAMP, respectively), we compared the pulmonary vasodilator capacity of each.

METHODS AND RESULTS

A total of 15 children with congenital heart disease and PHT who had elevated pulmonary vascular resistance (preoperative, n=10; immediately postoperative, n=5) were first given 20 ppm of iNO for 10 minutes; then, after baseline values were reached again, they were given aerosolized iloprost at 25 ng. kg(-1). min(-1) for another 10 minutes. Finally, iNO and iloprost were given simultaneously for 10 minutes. With iNO, the pulmonary vascular resistance and systemic vascular resistance ratio decreased from 0.48+/-0.38 to 0.27+/-0.16 (P:<0.001). Similarly, iloprost decreased the ratio from 0.49+/-0.38 to 0.26+/-0.11 (P:<0.05). The combination had no additional effect on the resistance ratio. Plasma cGMP increased from 17.6+/-11.9 to 34.7+/-21.4 nmol/L during iNO (P:<0.01), and plasma cAMP increased from 55.7+/-22.9 to 65.1+/-21.2 nmol/L during iloprost inhalation (P:<0.05).

CONCLUSIONS

In children with PHT and congenital heart disease, both iNO and aerosolized iloprost are equally effective in selectively lowering pulmonary vascular resistance through an increase in cGMP or cAMP, respectively. However, the combination of both vasodilators failed to prove more potent than either substance alone. Aerosolized iloprost might be an alternative to iNO for early testing of vascular reactivity and for the postoperative treatment of acute PHT.

[Prescribing of sildenafil by national insurance program physicians. What basic sexual medicine qualification is required?]

The role of sildenafil in the treatment of erectile dysfunction is discussed. Especially in primary care there is a necessity to weigh the individual cost-benefit-ratio. Functional analysis of erectile dysfunction, exclusion of psychiatric and organic comorbidity, identification of sexual deviance and couple counseling about the advantages and disadvantages of sildenafil prescription are the core prerequisites of sildenafil application in primary care. The counseling model of PLIS-SIT is proposed as a guideline for counseling process. Current approaches of education for general practitioners are reviewed and the integration in a recently developed training for management of psychiatry and psychosomatic illness in general medical settings is proposed. Finally open questions for research and quality management are discussed.

[Colonization by Ureaplasma urealyticum and chronic lung disease in premature newborn infants under 32 weeks of gestation]

Colonization of the respiratory tract of premature newborn infants by genital mycoplasma is suspected to be associated with chronic lung disease.

METHODS AND PATIENTS

We prospectively determined the prevalence of genital mycoplasma colonization with nasopharyngeal or endotracheal culture in preterm neonates younger than 32 weeks gestation and its possible association with the development of chronic lung disease in a prospective study.

RESULTS

Fifty-nine infants were enrolled and 11 (19%) were colonized with Ureaplasma urealyticum. In the subgroup of 45 ventilated infants, seven of seven U. urealyticum-positive infants developed chronic pulmonary disease versus ten of 38 (26%) of U. urealyticum-negative infants (relative risk [RR] = 3.8; 95% confidence interval [CI] 2.2 to 6.5, P < 0.001). U. urealyticum-colonized infants had a lower median birth weight (760 vs 1,083 g, P = 0.04), a lower gestational age (26 vs 28 weeks, P = 0.03), and a higher incidence of symptomatic patent ductus arteriosus (P = 0.03). These potential confounding factors may partially explain the association between U. urealyticum and chronic pulmonary disease. However, this association remained statistically significant when the analysis was restricted to infants with birth weight of 1,000 g or less (RR = 2.3; 95% CI 1.3 to 4, P = 0.02) or to infants with a patent ductus arteriosus (RR = 2; 95% CI 1.3 to 3.1, P = 0.02).

CONCLUSION

Colonization with U. urealyticum in ventilated preterm neonates younger than 32 weeks gestation is a significant risk factor of developing chronic pulmonary disease.

Hospital stay and short-term follow-up of children of drug-abusing mothers born in an urban community hospital--a retrospective review

In order to assess the current use of medical and social services of children of drug-abusing mothers in regard to their short term outcome in a Swiss urban community hospital, we compared hospital, private paediatricians and home nursing records of 37 of these children with 37 matched control children from birth to 18 months of age. Children of drug-abusing mothers (CDAM) experienced a longer neonatal hospital stay than control children with a median (25%-75%) of 26 days (10.5-52.5 days) versus 5 (5-6) days (P < 0.001), a substantial part of which, 8 days (3.5-26 days) versus 0 days (0-1 day) (P < 0.001) was not motivated by any specific medical treatment or nursing care. Before discharge, CDAM were referred to out of hospital nursing and social services for further management, but only 13% were effectively followed. More than 50% were lost to follow-up by their initial paediatrician after 1 year of life.

CONCLUSION

New ways to ensure better co-ordination between paediatricians and the social services (inside and outside the hospital) should be developed to shorten the neonatal hospitalisation period and improve the quality of follow-up.

First intention high-frequency oscillation with early lung volume optimization improves pulmonary outcome in very low birth weight infants with respiratory distress syndrome

OBJECTIVES

The lack of decline in chronic lung disease of prematurity despite the generalized use of surfactant and alternative modes of ventilation such as high-frequency oscillation (HFO) has been attributed to some misunderstanding of how HFO has to be used. We used a new ventilatory strategy in very low birth weight (VLBW) infants, by initiating HFO immediately after intubation and attempting early lung volume optimization before surfactant was administered.

STUDY DESIGN

The outcome of 32 VLBW infants, managed with first intention HFO over a period of 24 months (September 1, 1996 and August 31, 1998) was compared by chart review with 39 historical controls, consecutively managed with conventional mechanical ventilation (CMV) over a period of 24 months (January 1, 1994 and December 31, 1995).

SETTING

An 11-bed tertiary care pediatric and neonatal intensive care unit of a university teaching hospital.

RESULTS

The 2 groups of patients were similar in demographic distribution of birth weight, gestational age, race, and gender. Patients on first intention HFO were ventilator-dependent (median [95% confidence interval]: 5 [3-6] vs 14 [6-23] days) and oxygen-dependent (12 [4-17] vs 51 [20-60] days) for a shorter time than patients on CMV. The incidence of chronic lung disease at 36 weeks of gestational age was significantly lower in the HFO group compared with the CMV group (0% vs 34%).

CONCLUSIONS

First intention HFO with early lung volume optimization shortened the need for respiratory support and improved pulmonary outcome of VLBW infants with respiratory distress syndrome significantly.
