The role of neuromodulation in chronic functional constipation: a systematic review.

BACKGROUND: Chronic functional constipation is a highly prevalent disorder in which, when conservative measures fail to relieve symptoms, surgical interventions are sometimes indicated. In recent years, neuromodulation for the treatment of functional constipation has gained interest but its role and effectiveness are still unclear. The purpose of this review is to provide a systematic overview on the current literature on the different modalities of neurostimulation and their effect on chronic functional constipation in adults as reported in the literature. METHODS: A search in the literature for articles concerning the effect of different types of neuromodulation on constipation was performed in PubMed using extensive search terms for the different modalities of neuromodulation. Studies and trials were checked for eligibility. For all types of neuromodulation together, 27 articles were included. RESULTS: 17 studies were included on SNM (sacral nerve modulation). Although multiple studies show positive results on the effect of SNM in constipation, double-blind crossover RCT's (randomised controlled trials) showed no significant effect. 3 studies were included for tSNS (transcutaneous sacral nerve stimulation), 2 for PTNS (percutaneous tibial nerve stimulation) and 2 for TTNS (transcutaneous tibial nerve stimulation). Studies and trials on these modalities of neuromodulation reported ambiguous results on statistical significance of the effect. For transcutaneous IFC (interferential current therapy) 2 studies were included, which both reported a statistically significant effect on all outcomes. CONCLUSION: The beneficial effect of neuromodulation in chronic functional constipation remains questionable. However, neuro-modulation might be worth considering in patients refractory to treatment before turning to more invasive measures. Future research should shed more light on the effects of neuromodulation in constipation.

Therapeutic processes in multi-family groups for major depression: results of an interpretative phenomenological study.

BACKGROUND: Recent research indicates that different couple and family interventions are effective in the treatment of depressed patients. However, how these psychosocial interventions work, has been less well investigated. In order to better understand the underlying treatment processes, helpful treatment experiences of depressive patients and their partners were examined in a multi-family therapy group. METHOD: 24 patients hospitalized for depression and 20 partners participated in this study. Therapeutic factors were assessed using an open-ended questionnaire. Responses were analyzed using interpretative phenomenological approach (IPA). RESULTS: Eight recurring therapeutic factors were reported by both the patients and their partners: (1) Presence of others, (2) cohesion and understanding, (3) self-disclosure, (4) openness, (5) discussion, (6) insights, (7) observational experiences and (8) guidance from the therapist. LIMITATIONS: Results were not fed back to the participants following analysis and only therapeutic factors that operate on a conscious level could be identified. CONCLUSIONS: Several important therapeutic factors were identified in multi-family therapy groups for depression. These factors help to gain understanding into the processes, which should be emphasized in treatment and ought to be explored in future outcome and process research.

Post-traumatic severe fat embolism syndrome with uncommon CT findings.

Although the diagnosis of fat embolism syndrome is usually based on clinical findings, we describe ill-defined centrilobular and subpleural nodules in addition to ground-glass opacities and consolidation on a computed tomography scan of the chest in a trauma patient with fat embolism syndrome. The nodules presumably represent alveolar oedema, microhaemorrhage and an inflammatory response secondary to ischaemia and cytotoxic emboli in fat embolism syndrome. The literature of computed tomography findings in patients with fat embolism syndrome is reviewed and summarized.

Coronary involvement in the Churg-Strauss syndrome.

The Churg-Strauss syndrome (CSS) is a rare systemic disease characterised by vasculitis and peripheral eosinophilia in patients with an atopic constitution. Cardiac involvement is an important cause of morbidity and mortality yet coronary involvement is very rarely documented. We report the case of a 38 year old man presenting with fulminant heart failure. Coronary arteriography demonstrated extensive focal vasculopathy consistent with vasculitis. The diagnosis of CSS was established based upon the classical diagnostic criteria and corticosteroid treatment resulted in a spectacular remission of disease activity.
